CAUTIONARY NOTICE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements contained in or incorporated by reference into this prospectus supplement, including, without limitation, those related to our future operations, constitute “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 Exchange Act. The words “believe,” “estimate,” “expect,” “anticipate,” “intend,” “plan,” “seek,” “may” and similar

S-2

expressions or statements regarding future periods are intended to identify forward-looking statements. These forward-looking statements involve known and unknown risks, uncertainties and other important factors that could cause our actual results, performance or achievements, or industry results to differ materially from any predictions of future results, performance or achievements that we express or imply in this prospectus supplement or in the information contained in or incorporated by reference into this prospectus supplement. Some of the risks, uncertainties and other important factors that may affect future results include, among others:

•

Changes in general economic and business conditions, including the financial condition of our tenants and the value of our real estate assets;

•

Our continued qualification as a REIT for U.S. federal income tax purposes;

•

Heightened competition for tenants and potential decreases in property occupancy;

•

Potential changes in the financial markets and interest rates;

•

Volatility in our stock price and trading volume;

•

Our continuing ability to raise funds on favorable terms;

•

Our ability to successfully identify, acquire, develop and/or manage properties on terms that are favorable to us;

Potential increases in real estate construction costs;

Our ability to successfully dispose of properties on terms that are favorable to us, including, without limitation, through one or more transactions that are consistent with our previously disclosed strategic plans;

•

Other risks and uncertainties described herein, as well as those risks and uncertainties discussed from time to time in our other reports and other public filings with the SEC.

Although we presently believe that the plans, expectations and results expressed in or suggested by the forward-looking statements are reasonable, all forward-looking statements are inherently subjective, uncertain and subject to change, as they involve substantial risks and uncertainties beyond our control. New factors emerge from time to time, and it is not possible for us to predict the nature, or assess the potential impact, of each new factor on our business. Given these uncertainties, we caution you not to place undue reliance on these forward-looking statements. We undertake no obligation to update or revise any of our forward-looking statements for events or circumstances that arise after the statement is made, except as otherwise may be required by law.

This list of risks and uncertainties, however, is only a summary of some of the most important factors and is not intended to be exhaustive.

PROSPECTUS SUPPLEMENT SUMMARY

This summary highlights selected information about us. It may not contain all the information that may be important to you in deciding whether to invest in our common stock. You should read this entire prospectus supplement and the accompanying prospectus, together with the information incorporated by reference herein and therein, including the risk factors, financial data and related notes, before making an investment decision.

Company Overview

As of September 30, 2012, we:

•

Owned or jointly controlled 759 industrial, office, medical office and other properties, of which 741 properties with approximately 137.3 million square feet are in service and 18 properties with more than 4.7 million square feet are under development. The 741 in-service properties are comprised of 616 consolidated properties with more than 112.0 million square feet and 125 jointly controlled unconsolidated properties with more than 25.2 million square feet. The 18 properties under development consist of 15 consolidated properties with approximately 3.5 million square feet and three jointly controlled unconsolidated properties with more than 1.2 million square feet.

•

Owned, including through ownership interests in unconsolidated joint ventures, approximately 4,650 acres of land and controlled more than 1,600 acres through purchase options.

A key component of our overall strategy is to increase our investment in quality industrial properties in both existing and select new markets, expand our medical office portfolio nationally to take advantage of demographic trends and to reduce our investment in suburban office properties and other non-strategic assets.

Our headquarters and executive offices are located in Indianapolis, Indiana. In addition, we have 17 regional offices or significant operations in Alexandria, Virginia; Atlanta, Georgia; Baltimore, Maryland; Chicago, Illinois; Cincinnati, Ohio; Columbus, Ohio; Dallas, Texas; Houston, Texas; Minneapolis, Minnesota; Nashville, Tennessee; Orlando, Florida; Phoenix, Arizona; Raleigh, North Carolina; St. Louis, Missouri; Savannah, Georgia; Tampa, Florida; and Weston, Florida. We had more than 800 employees as of September 30, 2012.

Recent Developments

Acquisitions and Dispositions

During the third and fourth quarters, we executed acquisitions aggregating over $526.0 million in cost, which included the assumption of approximately $78.0 million in secured debt. The buildings are located in Chicago, Houston, Cincinnati, Northern California and Georgia and total 3.3 million square feet, and were 93% leased at closing. Acquisitions during the quarters consisted of 22 medical office buildings and four industrial buildings.

During the fourth quarter we sold a portfolio of six industrial properties in Indianapolis and one office property in Raleigh, totaling 471,584 square feet, for $26.0 million. We also entered into an agreement to sell an office building with proceeds anticipated to be approximately $34.0 million. This transaction is subject to certain closing conditions and is expected to close in the first quarter of 2013. These acquisitions and dispositions are in line with our asset strategy.

S-4

At December 31, 2012, our $519.0 million development pipeline, including joint ventures at our ownership share, was 73% pre-leased. 89% of the pipeline is built to suit projects. We estimate additions to projects in our development pipeline totaled approximately $119.0 million during the quarter. We selectively manage the size of our pipeline to be less than 10% of our total asset base.

Financing

During the fourth quarter we repaid loans of $60.5 million which primarily included $50.0 million of 5.450% Medium Term Unsecured Notes. We also sold 5,809,034 shares of common stock pursuant to our equity sales program with gross proceeds to us of $80.7 million. See below “Underwriting (Conflicts of Interest)”.

SUPPLEMENTAL RISK FACTORS

Investing in our common stock involves risks. In deciding whether to invest in our common stock, you should carefully consider the following risk factors and the risk factors included in our 2011 Annual Report on Form 10-K, in addition to the other information contained in this prospectus supplement and the accompanying prospectus and the information incorporated by reference herein and therein. The risks and uncertainties described below and in our 2011 Annual Report on Form 10-K are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently deem immaterial, also may become important factors that affect us. If any of these risks occurs, our business, financial condition or results of operations could be materially and adversely affected. In that case, the value of our common stock and your investment could decline.

Future sales or issuances of our common stock may dilute the ownership interest of existing shareholders and depress the trading price of our common stock.

Future sales or issuances of our common stock may dilute the ownership interests of our existing shareholders. In addition, future sales or issuances of substantial amounts of our common stock may be at prices below the offering price of the shares offered by this prospectus supplement and may adversely impact the market price of our common stock.

The price of our common stock may fluctuate significantly.

The market price of our common stock may fluctuate significantly in response to many factors, including:

•

actual or anticipated variations in our operating results or dividends;

•

changes in our funds from operations or earnings estimates;

•

our ability to meet quarterly estimates published by securities analysts, which may be based on assumptions which differ from our actual results;

•

publications of research reports about us or the real estate industry, generally;

•

increases in market interest rates that lead purchasers of our shares to demand a higher dividend yield;

•

changes in market valuations of similar companies;

•

adverse market reaction to any additional debt we incur in the future;

•

additions or departures of key management personnel;

•

actions by institutional shareholders;

•

speculation in the press or investment community;

•

the passage of legislation or other regulatory developments that adversely affect us or our industry;

•

the realization of any of the other risk factors included in, or incorporated by reference to, this prospectus supplement; and

•

general market and economic conditions.

In addition, many of the factors listed above are beyond our control. These factors may cause the market price of our common stock to decline, regardless of our financial condition, results of operations, business or prospects. It is impossible to ensure that the market price of our common stock will not fall in the future.

S-6

USE OF PROCEEDS

We expect to receive net proceeds from the sale of the common stock of approximately $497,225,000 million, after deducting underwriting discounts and estimated offering expenses. If the underwriters’ option to purchase additional shares is exercised in full, our net proceeds from the offering will be approximately $571,866,500 million, after deducting underwriting discounts and estimated offering expenses.

The underwriters and/or their affiliates act as documentation agent and/or lender under the revolving credit facility. As a result, the underwriters and/or their affiliates may receive more than five percent of the net proceeds of this offering. See “Underwriting (Conflicts of Interest).”

S-7

ADDITIONAL FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of certain additional federal income tax considerations with respect to our qualification as a REIT and the ownership of our common stock. Investors should review the discussion in the accompanying prospectus under the heading “Federal Income Tax Considerations” for a more detailed summary of the federal income tax consequences of the purchase, ownership and disposition of our common stock and our election to be subject to federal income tax as a REIT.

New Tax Rates for U.S. Individuals, Estates and Trusts

In the accompanying prospectus under the heading “Federal Income Tax Considerations,” there are various references to maximum tax rates applicable to U.S. individuals, estates and trusts through the end of 2012, when such reduced rates were scheduled to expire. On January 2, 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, or the 2012 Relief Act, which, among other things, permanently extends most of the reduced rates for U.S. individuals, estates and trusts with respect to ordinary income, qualified dividends and capital gains that had expired on December 31, 2012. The 2012 Relief Act, however, does not extend all of the reduced rates for high-income taxpayers. Beginning January 1, 2013, in the case of married couples filing joint returns with taxable income in excess of $450,000, heads of households with taxable income in excess of $425,000 and other individuals with taxable income in excess of $400,000, the maximum rates on ordinary income will be 39.6% (as compared to 35% prior to 2013) and the maximum rates on long-term capital gains and qualified dividend income will be 20% (as compared to 15% prior to 2013). REIT dividends generally are not treated as qualified dividend income. Estates and trusts have more compressed rate schedules. Prospective shareholders are urged to consult their tax advisors regarding the effect of the new tax rates and other tax provisions in the 2012 Relief Act on an investment in our common stock.

Unearned Income Medicare Tax

Under the Health Care and Education Reconciliation Act of 2010, amending the Patient Protection and Affordable Care Act, high-income U.S. individuals, estates, and trusts will be subject to an additional 3.8% tax on net investment income in tax years beginning after December 31, 2012. For these purposes, net investment income includes dividends and gains from sales of stock. In the case of an individual, the tax will be 3.8% of the lesser of the individuals’ net investment income or the excess of the individuals’ modified adjusted gross income over $250,000 in the case of a married individual filing a joint return or a surviving spouse, $125,000 in the case of a married individual filing a separate return, or $200,000 in the case of a single individual. U.S. shareholders that are individuals, estates or trusts should consult their tax advisors regarding the effect, if any, of this legislation on their ownership and disposition of our common stock.

Recent Changes in U.S. Federal Income Tax Withholding

After December 31, 2013, withholding at a rate of 30% will be required on dividends in respect of, and after December 31, 2016, withholding at a rate of 30% will be required on gross proceeds from the sale of shares of our common stock held by or through certain foreign financial institutions (including investment funds), unless such institution enters into an agreement with the Secretary of the Treasury (unless alternative procedures apply pursuant to an applicable intergovernmental agreement between the United States and the relevant foreign government) to report, on an annual basis, information with respect to shares in, and accounts maintained by, the institution to the extent such shares or accounts are held by certain U.S. persons or by certain non-U.S. entities that are wholly or partially owned by U.S. persons. Accordingly, the entity through which our shares are held will affect the determination of whether such withholding is required. Similarly, after December 31, 2013, dividends in respect of, and after December 31, 2016, gross proceeds from the sale of, our shares held by an investor that is a non-financial non-U.S. entity will be subject to withholding at a rate of 30%, unless such entity either (i) certifies to us that such entity does not have any “substantial U.S. owners” or (ii) provides certain information regarding the entity’s “substantial U.S. owners,” which we will in turn provide to the Secretary of the Treasury. Non-U.S. shareholders are encouraged to consult with their tax advisers regarding the possible implications of these rules on their investment in our common stock.

S-8

UNDERWRITING (CONFLICTS OF INTEREST)

Under the terms and subject to the conditions contained in the terms agreement and the underwriting agreement attached as Annex A thereto, which are collectively referred to herein as the “underwriting agreement,” dated the date of this prospectus supplement, the underwriters named below, for whom Morgan Stanley & Co. LLC and UBS Securities LLC are acting as representatives, have severally agreed to purchase, and we have agreed to sell to them, severally, the number of shares indicated below:

Wells Fargo Securities, LLC		1,200,000
Credit Suisse Securities (USA) LLC		1,200,000
Evercore Group LLC		1,200,000
Total:		36,000,000

The underwriters and the representatives are collectively referred to as the “underwriters” and the “representatives,” respectively. The underwriters are offering the shares of common stock subject to their acceptance of the shares from us and subject to prior sale. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the shares of common stock offered by this prospectus supplement are subject to the approval of certain legal matters by their counsel and certain other conditions. The underwriters are obligated to take and pay for all of the shares of common stock offered by this prospectus supplement if any such shares are taken. However, the underwriters are not required to take or pay for the shares covered by the underwriters’ option to purchase additional shares described below.

The underwriters initially propose to offer part of the shares of common stock directly to the public at the offering price listed on the cover page of this prospectus supplement and part to certain dealers. After the offering of the shares of common stock, the offering price and other selling terms may from time to time be varied by the representatives.

We have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus supplement, to purchase up to 5,400,000 additional shares of common stock at the public offering price listed on the cover page of this prospectus supplement, less underwriting discounts. To the extent the option is exercised, each underwriter will become obligated, subject to certain conditions, to purchase about the same percentage of the additional shares of common stock as the number listed next to the underwriter’s name in the preceding table bears to the total number of shares of common stock listed next to the names of all underwriters in the preceding table.

The following table shows the per share and total public offering price, underwriting discounts, and proceeds before expenses to us. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase up to an additional 5,400,000 shares of common stock.


			Total
	Per Share		No Exercise		Full Exercise
Public offering price	$	14.25	$	513,000,000	$	589,950,000
Underwriting discounts to be paid by us	$	0.43	$	15,390,000	$	17,698,500
Proceeds, before expenses, to us	$	13.82	$	497,610,000	$	572,251,500

The estimated offering expenses payable by us, exclusive of the underwriting discounts, are approximately $385,000.00.

We and our Operating Partnership have agreed with Morgan Stanley & Co. LLC and UBS Securities LLC that, subject to certain limited exceptions, without their prior written consent, we and our Operating Partnership will not directly or indirectly, during the period commencing on the date hereof and ending 45 days after the date hereof, sell, offer to sell, grant any option for the sale of, enter into any agreement to sell, or otherwise dispose of any shares of our common stock.

indirectly, any common stock or any securities convertible into or exercisable or exchangeable for common stock, (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the common stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of common stock or such other securities, in cash or otherwise, or (3) make any demand for or exercise any right with respect to, the registration of any common stock or any security convertible into or exercisable or exchangeable for common stock. The foregoing sentence does not apply, however, to (1) transactions relating to shares of common stock or other securities acquired in open market transactions after the completion of this offering, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made in connection with subsequent sales of common stock or other securities acquired in such open market transactions, (2) transfers of shares of common stock or any security convertible into or exercisable or exchangeable for common stock as a bona fide gift or (3) distributions of common stock or any security convertible into or exercisable or exchangeable for common stock to limited partners or shareholders, provided that in the case of any transfer or distribution pursuant to clause (2) or (3), (i) each donee or distributee shall sign and deliver a lock-up letter substantially in the form attached to the underwriting agreement and (ii) no filing under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of shares of common stock, shall be required or shall be voluntarily made during the restricted period referred to in the foregoing sentence. Morgan Stanley & Co. LLC and UBS Securities LLC, in their sole discretion, may release the common stock and other securities subject to the lock-up agreements described above in whole or in part at any time with or without notice.

In order to facilitate the offering of the common stock, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the common stock. Specifically, the underwriters may sell more shares than they are obligated to purchase under the underwriting agreement, creating a short position. A short sale is covered if the short position is no greater than the number of shares available for purchase by the underwriters under the option. The underwriters can close out a covered short sale by exercising the option or purchasing shares in the open market. In determining the source of shares to close out a covered short sale, the underwriters will consider, among other things, the open market price of shares compared to the price available under the option. The underwriters may also sell shares in excess of the option, creating a naked short position. 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 common stock in the open market after pricing that could adversely affect investors who purchase in this offering. As an additional means of facilitating this offering, the underwriters may bid for, and purchase, shares of common stock in the open market to stabilize the price of the common stock. These activities may raise or maintain the market price of the common stock above independent market levels or prevent or retard a decline in the market price of the common stock. The underwriters are not required to engage in these activities and may end any of these activities at any time.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or if indemnification is not allowed, to contribute to payments the underwriters may be required to make because of those liabilities.

A prospectus supplement in electronic format may be made available on websites maintained by one or more underwriters participating in this offering. The representatives may agree to allocate a number of shares of common stock to underwriters for sale to their online brokerage account holders. Internet distributions will be allocated by the representative to underwriters that may make Internet distributions on the same basis as other allocations.

Conflicts of Interest

From time to time, the underwriters and certain of their affiliates have engaged, and may in the future engage, in transactions with, and perform investment banking and/or commercial banking services for, us and our affiliates in the ordinary course of business and have received, and may in the future receive, compensation for their services. In addition, in the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and instruments of ours or our affiliates. If any of the underwriters or their affiliates has a lending relationship with us, certain of those underwriters

S-10

and their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the shares offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the shares offered hereby. The underwriters and their respective affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or financial instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

In September 2012, each of Morgan Stanley & Co. LLC, UBS Securities LLC and Wells Fargo Securities, LLC acted as a joint book-running manager and Credit Suisse Securities (USA) LLC acted as a co-manager in connection with the offering of $300 million of our Operating Partnership’s 3.875% Senior Notes Due 2022 and received an underwriting discount related thereto. In addition, each of Morgan Stanley & Co. LLC, UBS Securities LLC and Credit Suisse Securities (USA) LLC is a sales agent for our equity sales program pursuant to which we may issue and sell up to $200,000,000 in shares of common stock from time to time.

As described above under “Use of Proceeds,” we intend to use the net proceeds from this offering to reduce our outstanding indebtedness, including all or a portion of our outstanding borrowings under our existing revolving credit facility, and to redeem all of the outstanding shares of our Series O Preferred Shares. Wells Fargo Securities, LLC is a joint lead arranger and joint book runner, Wells Fargo Bank, National Association, an affiliate of Wells Fargo Securities, LLC, is a syndication agent and lender, Morgan Stanley Bank, N.A., an affiliate of Morgan Stanley & Co. LLC, is a documentation agent and lender, UBS Securities LLC is a documentation agent, and Credit Suisse AG, Cayman Islands Branch, an affiliate of Credit Suisse Securities (USA) LLC, and UBS AG, Stamford Branch, an affiliate of UBS Securities LLC, are lenders under the revolving credit facility. Additionally, UBS Securities LLC owns approximately 22,849 Series O Preferred Shares, which we intend to redeem with the net proceeds from this offering. As a result, the underwriters and/or their affiliates may receive a portion of the net proceeds of this offering and the amount received by them may exceed 5% of the net proceeds of this offering (not including the underwriting discounts). Nonetheless, in accordance with FINRA Rule 5121, the appointment of a qualified independent underwriter is not necessary in connection with this offering because, under FINRA Rule 5121, REITs are excluded from that requirement.

This prospectus supplement does not constitute an issue prospectus pursuant to Article 652a or Article 1156 of the Swiss Code of Obligations (“CO”) and our shares of common stock will not be listed on the SIX Swiss Exchange. Therefore, this prospectus supplement may not comply with the disclosure standards of the CO and/or the listing rules (including any prospectus schemes) of the SIX Swiss Exchange.

This offering is being made in Australia solely to “wholesale clients” for the purposes of section 761G of the Corporations Act 2001 (Australia) and, as such, no prospectus, product disclosure statement or other disclosure document in relation to our shares of common stock has been, or will be, prepared.

This prospectus supplement does not constitute an offer in Australia other than to wholesale clients. By submitting an application for our shares of common stock, you represent and warrant to us that you are a wholesale client for the purposes of section 761G of the Corporations Act 2001 (Australia).

Any offer to a recipient in Australia, and any agreement arising from acceptance of such offer, is personal and may only be accepted by the recipient. In addition, by applying for our shares of common stock you undertake to us that, for a period of 12 months from the date of issue of such shares, you will not transfer any interest in such shares to any person in Australia other than to a wholesale client.

S-12

or (iii) in other circumstances which do not result in the document being a “prospectus” within the meaning of the Companies Ordinance (Cap.32, Laws of Hong Kong).

Singapore

This prospectus supplement has not been registered as a prospectus with the Monetary Authority of Singapore, and in Singapore, the offer and sale of our shares of common stock is made pursuant to exemptions provided in sections 274 and 275 of the Securities and Futures Act, Chapter 289 of Singapore (“SFA”). Accordingly, this prospectus supplement and any other document or material in connection with the offer or sale, or invitation for subscription or purchase, of our shares of common stock may not be circulated or distributed, nor may our shares of common stock be offered or sold, or be made the subject of an invitation for subscription or purchase, whether directly or indirectly, to persons in Singapore other than (i) to an institutional investor as defined in Section 4A of the SFA pursuant to Section 274 of the SFA, (ii) to a relevant person as defined in section 275(2) of the SFA pursuant to Section 275(1) of the SFA, or any person pursuant to Section 275(1A) of the SFA, and in accordance with the conditions specified in Section 275 of the SFA or (iii) otherwise pursuant to, and in accordance with the conditions of, any other applicable provision of the SFA, in each case subject to compliance with the conditions (if any) set forth in the SFA. Moreover, this document is not a prospectus as defined in the SFA. Accordingly, statutory liability under the SFA in relation to the content of prospectuses would not apply. Prospective investors in Singapore should consider carefully whether an investment in our shares of common stock is suitable for them.

Where our shares of common stock are subscribed or purchased under Section 275 of the SFA by a relevant person which is:

(a)	a corporation (which is not an accredited investor as defined in Section 4A of the SFA), the sole business of which is to hold investments and the entire share capital of which is owned by one or more individuals, each of whom is an accredited investor; or

(b)	for a trust (where the trustee is not an accredited investor) whose sole purpose is to hold investments and each beneficiary of the trust is an individual who is an accredited investor,

shares of that corporation or the beneficiaries’ rights and interest (howsoever described) in that trust shall not be transferable for six months after that corporation or that trust has acquired the shares under Section 275 of the SFA, except:

(1)

to an institutional investor (for corporations under Section 274 of the SFA) or to a relevant person defined in Section 275(2) of the SFA, or any person pursuant to an offer that is made on terms that such shares of that corporation or such rights and interest in that trust are acquired at a consideration of not less than S$200,000 (or its equivalent in a foreign currency) for each transaction, whether such amount is to be paid for in cash or by exchange of securities or other assets, and further for corporations, in accordance with the conditions specified in Section 275 of the SFA;

S-13

(2)

where no consideration is given for the transfer; or

(3)

where the transfer is by operation of law.

In addition, investors in Singapore should note that our share of common stock acquired by them are subject to resale and transfer restrictions specified under Section 276 of the SFA, and they, therefore, should seek their own legal advice before effecting any resale or transfer of their shares.

CAUTIONARY NOTICE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements contained in or incorporated by reference into this prospectus, including, without limitation, those related to our future operations, constitute “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. The words “believe,” “estimate,” “expect,” “anticipate,” “intend,” “plan,” “seek,” “may” and similar expressions or statements regarding future periods are intended to identify forward-looking statements.

These forward-looking statements involve known and unknown risks, uncertainties and other important factors that could cause our actual results, performance or achievements, or industry results, to differ materially from any predictions of future results, performance or achievements that we express or imply in this prospectus or in the information incorporated by reference into this prospectus. Some of the risks, uncertainties and other important factors that may affect future results include, among others:

•

Changes in general economic and business conditions, including, without limitation, the continuing impact of the economic down-turn, which is having and may continue to have a negative effect on the fundamentals of our business, the financial condition of our tenants and the value of our real estate assets;

•

Our continued qualification as a real estate investment trust, or “REIT” for U.S. federal income tax purposes;

•

Heightened competition for tenants and potential decreases in property occupancy;

•

Potential changes in the financial markets and interest rates;

•

Volatility in our stock price and trading volume;

•

Our continuing ability to raise funds on favorable terms;

•

Our ability to successfully identify, acquire, develop and/or manage properties on terms that are favorable to us;

•

Potential increases in real estate construction costs;

•

Our ability to be flexible in the development and operation of joint venture properties;

•

Our ability to successfully dispose of properties on terms that are favorable to us;

•

Our ability to retain our current credit ratings;

•

Inherent risks in the real estate business, including, but not limited to, tenant defaults, potential liability relating to environmental matters and liquidity of real estate investments; and

•

Other risks and uncertainties described or incorporated by reference herein, including, without limitation, those risks and uncertainties discussed from time to time in our other reports and other public filings with the SEC.

This list of risks and uncertainties, however, is only a summary of some of the most important factors and is not intended to be exhaustive. Additional information regarding risk factors that may affect us is included under the caption “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011, which we filed with the SEC on February 24, 2012, and is updated by us from time to time in our subsequent Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and in other filings we make with the SEC.

Although we presently believe that the plans, expectations and results expressed in or suggested by the forward-looking statements are reasonable at the time they were made, all forward-looking statements are inherently uncertain, and subject to change, as they involve substantial risks and uncertainties beyond our control. New factors emerge from time to time, and it is not possible for us to predict the nature or assess the potential impact of each new factor on our business. Given these uncertainties, we caution you not to place undue reliance on these forward-looking statements. We have and undertake no obligation to update or revise any of our forward-looking statements for events or circumstances that arise after the statement is made, except as may be required by law.

DUKE REALTY AND THE OPERATING PARTNERSHIP

We are a self-administered and self-managed REIT, which began operations upon completion of our initial public offering in February 1986. In October 1993, we completed an additional common stock offering and acquired the rental real estate and service businesses of Duke Associates, whose operations began in 1972. As of December 31, 2011, our diversified portfolio of 748 rental properties (including 126 jointly controlled in-service properties with approximately 25.3 million square feet, five consolidated properties under development with more than 639,000 square feet and one jointly controlled property under development with approximately 274,000 square feet) encompasses more than 136.5 million rentable square feet and is leased by a diverse base of approximately 3,000 tenants whose businesses include government services, manufacturing, retailing, wholesale trade, distribution, healthcare and professional services. We also own, including through ownership interests in unconsolidated joint ventures, more than 4,800 acres of land and control an additional 1,630 acres through purchase options.

RISK FACTORS

An investment in our securities involves significant risks. You should carefully consider the risks and uncertainties and the risk factors set forth in the documents and reports filed with the SEC that are incorporated by reference into this prospectus, as well as any risks described in any applicable prospectus supplement, before you make an investment decision regarding the securities. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business operations and financial condition.

USE OF PROCEEDS

As required by the terms of the partnership agreement of the Operating Partnership, we must contribute to the Operating Partnership, in exchange for additional common or preferred units of the Operating Partnership, the net proceeds from any sale of shares of our capital stock (including any shares of our common stock or preferred stock or any depositary shares) and from the exercise of rights contained in any options, warrants or convertible or exchangeable securities containing the right to subscribe for or purchase such shares of capital stock. Unless otherwise specified in the prospectus supplement, we will use the net proceeds from the sale of the securities offered by this prospectus for general corporate purposes. These purposes may include, but are not limited to, the development and acquisition of additional rental properties and other acquisition transactions, the repayment of outstanding debt and improvements to properties in our portfolio.

Unless otherwise set forth in a prospectus supplement, we will not receive any proceeds in the event that securities are sold by a selling securityholder.

(6)	The ratio is less than 1.0; deficit of $35.9 million exists for the year ended December 31, 2008.

For purposes of computing these ratios, earnings have been calculated by adding fixed charges, excluding capitalized interest, to income (loss) from continuing operations before gains or losses on land and depreciated property sales and (if applicable) minority interest in the Operating Partnership. Fixed charges consist (if applicable) of interest costs, whether expensed or capitalized, the interest component of rental expense and amortization of debt issuance costs.

DESCRIPTION OF DEBT SECURITIES

The following summary outlines some of the material terms of the Operating Partnership’s non-convertible debt securities which could be senior debt securities or subordinated debt securities. The debt securities may consist of debentures, notes or other evidences of indebtedness, which may be guaranteed on a senior or subordinated basis by Duke Realty. The specific terms of any debt securities and the extent, if any, to which these general terms and provisions may or may not apply to the debt securities will be described in the prospectus supplement relating to the particular series of debt securities.

The Operating Partnership’s debt securities will be issued under an indenture, dated as of July 28, 2006, by and between the Operating Partnership and The Bank of New York Mellon Trust Company, N.A. (as successor to J.P. Morgan Trust Company, National Association), as trustee. The trustee’s office is currently located at Global Corporation Trust, 2 N. LaSalle Street, Suite 1020, Chicago, Illinois 60602. We have filed the indenture with the SEC, and the Trust Indenture Act of 1939 governs the indenture. The following description summarizes only the material provisions of the indenture. Accordingly, you should read the indenture, together with any applicable supplemental indenture(s), because it, and not this description, defines your rights as a holder of debt securities issued by the Operating Partnership.

General

The debt securities will be direct, unsecured obligations of the Operating Partnership. The senior debt securities will rank equally with all other senior debt of the Operating Partnership and the subordinated debt securities will rank equally with all other subordinated debt of the Operating Partnership, and will be subordinated to all of our existing and future senior debt. The debt securities will be effectively subordinated to the prior claims of each secured mortgage lender to any specific property that secures such lender’s mortgage.

The Operating Partnership may issue debt securities in one or more series without limit as to aggregate principal amount. We can establish an issue of debt securities as sole general partner of the Operating Partnership by a resolution of our board of directors or by a supplemental indenture. All debt securities of one series need not be issued at the same time, and a series may generally be reopened for additional issuances without the consent of the holders of the debt securities of the series.

The indenture provides that there may be more than one trustee, each with respect to one or more series of debt securities. Any trustee under the indenture may resign or be replaced with a successor trustee. Upon written notice, a trustee may be removed by act of the holders of a majority in principle amount of the outstanding debt securities of the series with respect to which the trustee acts as trustee. Except as otherwise described in this prospectus, any action by a trustee may be taken only with respect to the debt securities for which it is trustee under the indenture.

A prospectus supplement will describe the specific terms of any series of debt securities the Operating Partnership offers, including:

•

the title and type of the debt securities;

•

whether that series of debt securities constitutes senior or subordinated debt securities;

•

the aggregate principal amount of the series of debt securities and any limit on the total principal amount of that series;

•

the price at which the Operating Partnership will issue the debt securities;

•

the dates on which the Operating Partnership will pay the principal of the debt securities;

•

the fixed or variable rate at which the debt securities will bear interest, or the method to determine the interest rate;

•

the basis upon which the Operating Partnership will calculate interest on the debt securities if other than a 360-day year of twelve 30-day months;

•

the timing and manner of making principal, interest and any premium payments on the debt securities;

•

the circumstances under which the Operating Partnership may defer interest payments;

•

if other than the trustee, the identity of each registrar and/or paying agent for the debt securities of the series;

•

the place where:

•

the Operating Partnership can make payments of the debt securities;

•

the debt securities can be surrendered; and

•

the holder may serve notices about the debt securities and the indenture, if other than as described in this prospectus;

•

the portion of the principal amount of the debt securities payable upon acceleration, if it is other than the full principal amount;

•

whether and under what conditions the Operating Partnership or the holders may redeem the debt securities;

•

any sinking fund or similar provisions;

•

the currency in which the Operating Partnership will pay principal, interest and any premium payments on the debt securities, if other than U.S. dollars;

•

the events of default or covenants of the debt securities, if they are different from or in addition to those described in this prospectus;

•

whether the Operating Partnership will issue the debt securities in certificated or book-entry form;

•

whether the Operating Partnership will issue the debt securities in registered or bearer form and their denominations, if other than $1,000 for registered form or $5,000 for bearer form;

•

whether the defeasance and covenant defeasance provisions described in this prospectus apply to the debt securities or are different in any manner;

•

the time, manner and place for the debt securities to be authenticated and delivered, if the debt securities are to be issued upon the exercise of debt warrants;

•

whether and under what circumstances the Operating Partnership will pay additional amounts on the debt securities for any tax, assessment or governmental charge and, if so, whether the Operating Partnership will have the option to redeem the debt securities instead of paying these amounts; and

•

any other terms of the debt securities.

Some debt securities may provide for less than the entire principal amount to be payable upon acceleration of their maturity, which we refer to as “original issue discount securities.” The prospectus supplement will describe any material federal income tax, accounting and other considerations applicable to any such original issue discount securities.

Denominations, Interest, Registration and Transfer

Unless otherwise described in the prospectus supplement, the Operating Partnership will issue debt securities in denominations of:

•

$1,000 if they are in registered form;

•

$5,000 if they are in bearer form; or

•

any denomination if they are in global form.

Unless otherwise specified in the prospectus supplement, the principal, interest and any premium on debt securities will be payable at the corporate trust office of the trustee. The Operating Partnership may change the paying agent or registrar for a series of debt securities without prior notice to the holders of the debt securities, and the Operating Partnership or any of its subsidiaries may act as paying agent or registrar.

If any interest date or a maturity date falls on a day that is not a business day, the required payment will be made on the next business day as if it were made on the date the payment was due and no interest will accrue on the amount so payable for the period from and after such interest payment date or such maturity date, as the case may be. For purposes of the indenture, a “business day” is any day, other than a Saturday or Sunday, on which banking institutions in New York City are open for business.

Subject to limitations imposed upon debt securities issued in book-entry form, you may exchange debt securities for different denominations of the same series or surrender debt securities for transfer at the corporate trust office of the trustee. Every debt security surrendered for transfer or exchange must be duly endorsed or accompanied by a written instrument of transfer. The Operating Partnership will not require the holder to pay any service charge for any transfer or exchange, but the trustee or the Operating Partnership may require the holder to pay any applicable tax or other governmental charge.

Neither the Operating Partnership nor the trustee is required to:

•

issue, transfer or exchange any debt security if the debt security may be among those selected for redemption during a 15-day period prior to the date of selection;

•

transfer or exchange any registered security selected for redemption in whole or in part, except, in the case of a registered security to be redeemed in part, the portion not to be redeemed;

•

exchange any bearer security selected for redemption, except that the holder may exchange the bearer security for a registered security of that series if the holder simultaneously surrenders the registered security for redemption; or

•

issue, transfer or exchange any debt security that the holder surrenders for repayment.

Guarantees

The debt securities issued by the Operating Partnership may be guaranteed on a senior or subordinated basis by Duke Realty, which guarantees would guarantee the due and punctual payments of principal, premium, if any, and interest on such debt securities, and the due and punctual payment of any sinking fund payments, if any, thereon, when and as the same shall become due and payable, including without limitation, at maturity, whether scheduled or as the result of acceleration, call for redemption or otherwise. The applicability and terms of any such guarantees relating to a series of debt securities of the Operating Partnership will be set forth in the prospectus supplement relating to such debt securities.

Merger, Consolidation or Sale

The Operating Partnership may consolidate with, or sell, lease or convey all or substantially all of its assets to, or merge into, any other entity, provided that:

•

the Operating Partnership is the continuing entity, or the successor entity formed by the transaction or which received the transfer of assets is organized and existing under the laws of the United States or a state thereof and expressly assumes payment of the principal, interest and any premium on all the debt securities and the performance and observance of all of the covenants and conditions contained in the indenture;

•

immediately after giving effect to the transaction and treating any debt that becomes an obligation of the Operating Partnership or any subsidiary as a result of the transaction as having been incurred by the Operating Partnership or such subsidiary at the time of such transaction, no event of default under the indenture, and no event which, after notice or the lapse of time, would become an event of default, has occurred and is continuing; and

•

the Operating Partnership delivers to the trustee an officers’ certificate and legal opinion covering these conditions.

Except for the above restrictions, the indenture does not limit the ability of the Operating Partnership to enter into any of the following types of transactions:

•

a highly leveraged or similar transaction involving the Operating Partnership, the management of the Operating Partnership or Duke Realty, or any affiliate of any such party;

•

a change of control; or

•

a reorganization, restructuring, merger or similar transaction involving the Operating Partnership that may adversely affect the holders of the debt securities.

In addition, subject to the limitations on merger, consolidation or sale described above, the Operating Partnership may enter into transactions in the future, such as the sale of all or substantially all of its assets or the merger or consolidation of the Operating Partnership, that would increase the amount of the Operating Partnership’s debt or substantially reduce or eliminate its assets, which may have an adverse effect on the Operating Partnership’s ability to service its debt, including the debt securities.

Financial Covenants

Limitations on Incurrence of Debt. The Operating Partnership will not directly or indirectly incur any debt, other than subordinate intercompany debt, if, after giving effect to the incurrence of the additional debt, the aggregate principal amount of all outstanding debt of the Operating Partnership on a consolidated basis determined in accordance with generally accepted accounting principles, or “GAAP,” is greater than 60% of its then-current total assets.

The Operating Partnership also will not directly or indirectly incur any debt if the ratio of consolidated income available for debt service to the amount that is expensed for interest on debt for the four most recent fiscal quarters would have been less than 1.5 to 1.0 on a pro forma basis after giving effect to the incurrence of the debt and to the application of the proceeds from the debt. In making this calculation, we assume that:

•

the new debt and any other debt incurred by the Operating Partnership since the first day of the four-quarter period and the application of the proceeds from the new debt, including to refinance other debt, had occurred at the beginning of the period;

•

the repayment or retirement of any other debt by the Operating Partnership since the first day of the four-quarter period had been repaid or retired at the beginning of the period (except that the amount of debt under any revolving credit facility is computed based upon the average daily balance of that debt during the period);

•

the income earned on any increase in total assets since the end of the four-quarter period had been earned, on an annualized basis, during the period; and

•

in the case of any acquisition or disposition by the Operating Partnership of any assets since the first day of the four-quarter period, the acquisition or disposition or any related repayment of debt had occurred as of the first day of the period with the appropriate adjustments with respect to the acquisition or disposition being included in the pro forma calculation.

In addition, the Operating Partnership will not directly or indirectly incur any secured debt if, after giving effect to the incurrence of the additional secured debt, the aggregate principal amount of all outstanding secured debt of the Operating Partnership on a consolidated basis determined in accordance with GAAP is greater than 40% of its then-current total assets.

Maintenance of Total Unencumbered Assets. The Operating Partnership must maintain total unencumbered assets of at least 150% of the aggregate outstanding principal amount of all outstanding unsecured debt.

Operating Covenants

Existence. Except as described above under “—Merger, Consolidation or Sale,” the Operating Partnership must preserve and keep in full force and effect its existence, rights and franchises. However, the Operating Partnership need not preserve any right or franchise if we determine that its preservation is no longer desirable in the conduct of our business and that its loss is not materially disadvantageous to the holders of the debt securities.

Maintenance of Properties. The Operating Partnership must maintain all of its material properties in good condition, repair and working order, supply all properties with all necessary equipment and make all necessary repairs, renewals, replacements and improvements so that we may properly and advantageously conduct our business at all times. However, the Operating Partnership may sell its properties for value in the ordinary course of business.

Insurance. The Operating Partnership must keep all of its insurable properties fully insured against loss or damage with financially sound and reputable insurance companies.

Payment of Taxes and Other Claims. The Operating Partnership must pay, before they become delinquent:

•

all taxes, assessments and governmental charges; and

•

all lawful claims for labor, materials and supplies that, if unpaid, might by law become a lien upon any property.

However, the Operating Partnership is not required to pay any tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings.

Provision of Financial Information. The Operating Partnership will provide the trustee and the holders of debt securities with copies of its annual reports and quarterly reports. The Operating Partnership will continue to file timely all annual, quarterly and other periodic reports with the SEC regardless of whether or not the securities laws require the Operating Partnership to do so.

Events of Default, Notice and Waiver

The following are events of default with respect to any series of debt securities issued under the indenture:

•

default for 30 days in the payment of any installment of interest on any debt security of the series;

•

default in the payment of the principal or any premium on any debt security of the series at its maturity;

•

default in making any sinking fund payment as required for any debt security of the series;

•

default in the payment of an aggregate principal amount exceeding $5,000,000 of any recourse debt of the Operating Partnership (or of any subsidiary which the Operating Partnership has guaranteed or for which it is liable), if the default continued beyond the expiration of any applicable grace period and resulted in the acceleration of the maturity of the debt, but only if such debt is not discharged or such acceleration is not rescinded or annulled after notice;

•

bankruptcy, insolvency or reorganization, or court appointment of a receiver, liquidator or trustee of the Operating Partnership or any significant subsidiary or any of their respective property;

•

default in the performance of any other covenant contained in the indenture, other than covenants that do not apply to the series, and the default continues for 60 days after notice; and

•

any other event of default provided with respect to that particular series of debt securities.

If an event of default occurs and continues, the trustee or the holders of at least 25% in principal amount of the outstanding debt securities of that series may declare the principal amount of all of the debt securities of that series to be due and payable immediately. If the debt securities of that series are original issue discount securities or indexed securities, the prospectus supplement will describe the portion of the principal amount required to make the declaration. If this happens and the Operating Partnership thereafter cures the default, the holders of at least a majority in principal amount of outstanding debt securities of that series can void the acceleration.

The indenture also provides that the holders of at least a majority in principal amount of the outstanding debt securities of a series may waive any past default with respect to that series, except a default in payment or a default of a covenant or other indenture provision that can only be modified with the consent of the holder of each outstanding debt security affected.

The indenture provides that no holders of any series may institute any judicial or other proceedings with respect to the indenture or for any remedy under the indenture, except in the case of failure of the trustee to act for 60 days after it has received a written request to institute proceedings for an event of default from the holders of at least 25% in principal amount of the outstanding debt securities of that series and an offer of indemnity reasonably satisfactory to it. However, this provision will not prevent any holder from instituting suit for the enforcement of any payment due on the debt securities.

Subject to provisions in the indenture relating to its duties in case of default, the trustee is under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any holders, unless the holders offer to the trustee reasonable security or indemnity. The holders of at least a majority in principal amount of the outstanding debt securities of a series (or of all debt securities then outstanding under the indenture, if applicable) have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee. However, the trustee may refuse to follow any direction that:

•

is in conflict with any law or the indenture;

•

may subject the trustee to personal liability; or

•

may be unduly prejudicial to the holders not joining in the direction.

The Operating Partnership must file annually with the trustee an officers’ certificate regarding the Operating Partnership’s compliance with the indenture, and in the event of noncompliance, specifying such noncompliance and the nature and status thereof. The trustee must give notice to the holders of debt securities within 90 days of a default unless the default has been cured or waived. However, if the trustee considers it to be in the interest of the holders, the trustee may withhold notice of any default except a payment default.

Modification of the Indenture

The consent of the holders of at least a majority in principal amount of all outstanding debt securities affected by a modification or amendment of the indenture is required to modify or amend the indenture. However, holders of each of the debt securities affected by the modification must consent to modifications that have the following effects:

•

change the stated maturity of the principal, interest or premium on any debt security;

•

reduce the principal amount of, or the rate or amount of interest on, or any premium payable on redemption of, any debt security, or adversely affect any right of repayment of the holder of any debt security;

•

change the place or currency for payment of principal, interest or premium on any debt security;

•

impair the right to institute suit for the enforcement of any payment on any debt security;

•

reduce the percentage of outstanding debt securities of a series necessary to modify or amend the indenture, waive compliance with provisions of the indenture or defaults and consequences under the indenture or reduce the quorum or voting requirements set forth in the indenture; or

•

modify any of the provisions discussed above or any of the provisions relating to the waiver of past defaults or covenants, except to increase the required percentage to take the action or to provide that other provisions may not be modified or waived without the consent of the holder.

The indenture provides that the holders of at least a majority in principal amount of a series of outstanding debt securities is required to waive compliance by the Operating Partnership with covenants relating to that series.

The Operating Partnership and the trustee can modify the indenture without the consent of any holder for any of the following purposes:

•

to evidence the succession of another person to the Operating Partnership as obligor;

•

to add to the covenants of the Operating Partnership for the benefit of the holders or to surrender any right or power conferred upon the Operating Partnership;

•

to add events of default for the benefit of the holders;

•

to add or change any provisions of the indenture to facilitate the issuance of, or to liberalize the terms of, debt securities in bearer form, or to permit or facilitate the issuance of debt securities in uncertificated form, so long as it does not materially adversely affect the interests of any of the holders;

•

to change or eliminate any provision of the indenture, so long as any such change or elimination becomes effective only when there are no debt securities outstanding of any series previously created which are entitled to the benefit of those provisions;

•

to secure the debt securities;

•

to establish the form or terms of debt securities of any series;

•

to provide for the acceptance of appointment by a successor trustee to facilitate the administration of the trusts under the indenture by more than one trustee;

•

to cure any ambiguity, defect or inconsistency in the indenture, so long as the action does not materially adversely affect the interests of any of the holders;

•

to supplement any of the provisions of the indenture to the extent necessary to permit or facilitate defeasance and discharge of any series, so long as the action does not materially adversely affect the interests of any of the holders.

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

•

the principal amount of an original issue discount security that is deemed to be outstanding is the amount of its principal that would be due and payable as of the date of determination upon declaration of acceleration of maturity;

•

the principal amount of a debt security denominated in a foreign currency that is deemed outstanding is the U.S. dollar equivalent of the principal amount, determined on the issue date for the debt security;

•

the principal amount of an indexed security that is deemed outstanding is the principal face amount of the indexed security at original issuance, unless otherwise provided with respect to the indexed security; and

•

debt securities that are directly or indirectly owned by the Operating Partnership are disregarded.

The indenture contains provisions for convening meetings of the holders of debt securities of a series. The trustee, the Operating Partnership or the holders of at least 10% in principal amount of the outstanding debt securities of a series may call a meeting. Except for any consent that the holder of each debt security affected by modifications and amendments of the indenture must give, the affirmative vote of the holders of a majority in principal amount of the outstanding debt securities of that series will be sufficient to adopt any resolution presented at a meeting at which a quorum is present. However, except as referred to above, any resolution with respect to any request, demand, authorization, direction, notice, consent, waiver or other action that may be made, given or taken by the holders of a specified percentage less than a majority in principal amount of the outstanding debt securities of a series may be adopted at a meeting at which a quorum is present only by the affirmative vote of the holders of the specified percentage. Any resolution passed or decision taken at any meeting of holders duly held in accordance with the indenture will be binding on all holders of debt securities of that series. The quorum at any meeting will be persons holding or representing a majority in principal amount of the outstanding debt securities of a series. However, if any action is to be taken at a meeting with respect to a consent or waiver that may be given by the holders of not less than a specified percentage in principal amount of the outstanding debt securities of a series, the persons holding or representing that specified percentage will constitute a quorum.

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

•

there will be no minimum quorum requirement for such meeting; and

•

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

Discharge, Defeasance and Covenant Defeasance

Some debt securities may provide that the Operating Partnership may discharge obligations to holders of any series of debt securities that have not already been delivered to the trustee for cancellation and that either have

become due and payable or will become due and payable within one year or scheduled for redemption within one year by irrevocably depositing with the trustee, in trust, funds sufficient to pay the principal, interest and any premium on the series to the stated maturity or redemption date.

As long as the holders of the debt securities will not recognize any resulting income, gain or loss for federal income tax purposes, the Operating Partnership may elect either:

•

to defease and discharge itself from all of its obligations with respect to the debt securities, which we refer to as “defeasance;” or

•

to release itself from its obligations under particular sections of the indenture, which we refer to as “covenant defeasance.”

In order to make a defeasance election, the Operating Partnership must irrevocably deposit with the trustee a sufficient amount to pay the principal, interest and any premium on the debt securities, and any mandatory sinking fund or analogous payments on the debt securities, on the scheduled due dates. The deposit may be either an amount in the currency in which the debt securities are payable at stated maturity, or government obligations, or a combination of both.

If the Operating Partnership elects covenant defeasance with respect to any debt securities and the debt securities are declared due and payable because of the occurrence of any event of default still applicable to the debt securities, the amounts deposited with the trustee may not be sufficient to pay amounts due on the debt securities at the time of the acceleration resulting from the event of default. If this occurs, the Operating Partnership will remain liable to make payment of these amounts due at the time of acceleration.

The prospectus supplement may exclude or may further describe any provisions permitting defeasance or covenant defeasance with respect to the debt securities of a particular series.

Book-Entry Debt Securities

The debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with a depositary identified in the prospectus supplement. Global securities may be issued in either registered or bearer form and in either temporary or permanent form. Payments of principal, interest and any premium on a series of debt securities represented by a global security will be made to the depositary.

We anticipate that any global securities will be deposited with The Depository Trust Company, or “DTC,” New York, New York, that the global securities will be registered in the name of DTC’s nominee, and that the following provisions will apply to the depository arrangements with respect to the global securities. The prospectus supplement will describe additional or differing terms of the depository arrangement involving any series of debt securities issued in the form of global securities.

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

•

will not be entitled to have debt securities represented by the global security registered in their names;

•

will not receive or be entitled to receive physical delivery of debt securities in the form of a certificate; and

•

will not be considered the record owners or holders of debt securities under the indenture.

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

Debt securities represented by a global security will be exchangeable for debt securities in certificated form with the same terms in authorized denominations only if:

•

DTC notifies us that it is unwilling or unable to continue as depository or if DTC ceases to be a clearing agency registered under applicable law and the Operating Partnership does not appoint a successor depository within 90 days;

•

an event of default under the indenture with respect to the debt securities has occurred and is continuing and the beneficial owners representing a majority in principal amount of the debt securities represented by the global security advise DTC to cease acting as depository; or

•

the Operating Partnership determines at any time that all debt securities of a series will no longer be represented by a global security.

We obtained the following information concerning DTC and its book-entry system from sources, including DTC, that we believe to be reliable, but we take no responsibility for the accuracy of this information.

DTC will act as securities depository for the debt securities. The debt securities will be issued as fully registered securities registered in the name of Cede & Co., which is DTC’s partnership nominee. One fully-registered debt security certificate will be issued for each issue of debt securities, each in the aggregate principal amount of such issue, and will be deposited with DTC. If, however, the aggregate principal amount of any issue exceeds $500 million, one certificate will be issued with respect to each $500 million of principal amount, and an additional certificate will be issued with respect to any remaining principal amount of such issue.

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that its participants deposit with DTC. DTC also facilitates the settlement among participants of securities transactions, including transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, thereby eliminating the need for physical movement of securities certificates. Direct participants of DTC include securities brokers and dealers, banks, trust companies, clearing corporations and other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to DTC’s system also is available to others, including securities brokers and dealers and banks and trust companies that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC.

Purchases of debt securities under the DTC system must be made by or through direct participants, which will receive a credit for the debt securities on DTC’s records. The ownership interest of each beneficial owner or each actual purchaser of each debt security is to be recorded on the direct and indirect participants’ records. A beneficial owner of debt securities will not receive written confirmation from DTC of its purchase, but is expected to receive a written confirmation providing details of the transaction, as well as periodic statements of its holdings, from the participant through which the beneficial owner entered into the transaction. Transfers of ownership interests in debt securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the debt securities, unless the use of the book-entry system for the debt securities is discontinued.

To facilitate subsequent transfers, any certificate representing debt securities that is deposited with, or on behalf of, DTC is registered in the name of its nominee, Cede & Co, or such other name as may be requested by an authorized representative of DTC. The deposit of the certificate with, or on behalf of, DTC and its registration in the name of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of the actual beneficial

owners of the certificate representing the debt securities. DTC’s records reflect only the identity of the direct participants to whose accounts the debt securities are credited, which may or may not be the beneficial owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers.

Delivery of notices and other communications by DTC to direct participants, by direct participants to indirect participants, and by direct and indirect participants to beneficial owners, will be governed by arrangements among them and any statutory or regulatory requirements as may be in effect from time to time.

Redemption notices shall be sent to DTC. If less than all of the debt securities within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in such issue to be redeemed.

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

Redemption proceeds, distributions, and dividend payments on the debt securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information from the Operating Partnership or paying agent, on payable date in accordance with their respective holdings shown on DTC’s records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such participant and not of DTC, the paying agent, or the Operating Partnership, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds, distributions, and dividend payments to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of the Operating Partnership or paying agent, disbursement of such payments to direct participants will be the responsibility of DTC, and disbursement of such payments to the beneficial owners will be the responsibility of direct and indirect participants.

A beneficial owner will give notice of any option to elect to have its debt securities repaid by the Operating Partnership, through its participant, to the trustee, and will effect delivery of the debt securities by causing the direct participant to transfer the participant’s interest in the global security or securities representing the debt securities, on DTC’s records, to the trustee. The requirement for physical delivery of debt securities in connection with a demand for repayment will be deemed satisfied when the ownership rights in the global security or securities representing the debt securities are transferred by direct participants on DTC’s records.

DTC may discontinue providing its services as securities depository with respect to a series of debt securities at any time by giving reasonable notice to the Operating Partnership or the paying agent. Under such circumstances, in the event that a successor depository is not obtained, Security certificates are required to be printed and delivered.

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

Unless stated otherwise in the applicable prospectus supplement, any underwriters, dealers or agents with respect to any series of debt securities issued as global securities will be direct participants in DTC.

None of the Operating Partnership, Duke Realty, any underwriter, dealer or agent, the trustee or any paying agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial interests in a global security, or for maintaining, supervising or reviewing any records relating to these beneficial interests.

Any additional or different terms of the depositary arrangement with respect to a series of debt securities will be described in the prospectus supplement relating to such series.

DESCRIPTION OF PREFERRED STOCK

General

Under Duke Realty’s articles of incorporation, the board of directors is authorized to issue up to 5 million shares of preferred stock in one or more series and with rights, preferences, privileges and restrictions that they may fix or designate without any further vote or action by Duke Realty’s shareholders. As of December 31, 2011, the following series of preferred stock were outstanding:

•

6.625% Series J Cumulative Redeemable Preferred Stock, of which 396,230 shares are outstanding;

•

6.500% Series K Cumulative Redeemable Preferred Stock, of which 598,200 shares are outstanding;

•

6.600% Series L Cumulative Redeemable Preferred Stock, of which 796,300 shares are outstanding;

•

6.950% Series M Cumulative Redeemable Preferred Stock, of which 673,090 shares are outstanding; and

•

8.375% Series O Cumulative Redeemable Preferred Stock, of which 711,820 shares are outstanding.

Terms

When Duke Realty issues shares of preferred stock, those shares will be fully paid and non-assessable. The preferred stock will not have any preemptive rights.

The specific terms of any new series of preferred stock offered will be reflected in an amendment to Duke Realty’s articles of incorporation. A prospectus supplement will describe these specific terms, including:

•

the title and stated value;

•

the number of shares, liquidation preference and offering price;

•

the dividend rate, dividend periods and payment dates;

•

the date on which dividends begin to accrue or accumulate;

•

any auction and remarketing procedures;

•

any retirement or sinking fund requirement;

•

the price and the terms and conditions of any redemption right;

•

the price and the terms and conditions of any conversion or exchange right;

•

any listing on any securities exchange;

•

whether interests will be represented by depositary shares;

•

any voting rights;

•

the relative ranking and preferences as to dividends, liquidation, dissolution or winding up;

•

any limitations on issuing any series of preferred stock ranking senior to or on a parity with the series of preferred stock as to dividends, liquidation, dissolution or winding up;

•

any limitations on direct or beneficial ownership and restrictions on transfer; and

•

any other specific terms, preferences, rights, limitations or restrictions.

Rank

Unless otherwise described in the prospectus supplement, the preferred stock will have the following ranking as to dividends, liquidation, dissolution or winding up:

•

senior to Duke Realty’s common stock and to all other equity securities ranking junior to the preferred stock;

•

on a parity with all equity securities issued by Duke Realty which by their terms rank on a parity with the preferred stock; and

•

junior to all equity securities issued by Duke Realty which by their terms rank senior to the preferred stock.

Dividends

If declared by Duke Realty’s board of directors, preferred shareholders will be entitled to receive cash dividends at the rate set forth in the prospectus supplement. Duke Realty will pay dividends to shareholders of record on the record date fixed by Duke Realty’s board of directors.

The prospectus supplement will specify whether dividends on any series of preferred stock are cumulative or non-cumulative. If dividends are cumulative, they will be cumulative from the date set forth in the prospectus supplement. If dividends are non-cumulative and Duke Realty’s board of directors does not declare a dividend payable on a dividend payment date, then the holders of that series will have no right to receive a dividend, and Duke Realty will have no obligation to pay an accrued dividend later for the missed dividend period, whether or not the board of directors declares dividends on the series on any future date.

If any preferred stock is outstanding, Duke Realty will not declare or pay dividends on, or redeem, purchase or otherwise acquire any shares of, its common stock or any capital stock ranking junior to a series of preferred stock, other than dividends paid in or conversions or exchanges for common stock or other capital stock junior to the preferred stock, unless:

•

if the series of preferred stock has cumulative dividends, Duke Realty has declared and paid full cumulative dividends for all past and current dividend periods or declared and reserved funds for payment before or at the same time as the declaration and payment on the junior series; or

•

if the series of preferred stock does not have cumulative dividends, Duke Realty has declared and paid full dividends for the current dividend period or declared and reserved funds for payment before or at the same time as the declaration and payment on the junior series.

When Duke Realty does not pay dividends on shares from more than one series of preferred stock ranking in parity as to dividends in full (or has not reserved a sufficient sum for full payment), all of these dividends will be declared on a pro rata basis so that the amount of dividends declared per share in each series will in all cases bear the same ratio of accrued dividends owed. These pro rata payments per share will not include interest, nor will those payments include any accumulated unpaid dividends from prior periods if the dividends in question are non-cumulative.

Redemption

If specified in the applicable prospectus supplement, Duke Realty will have the right to redeem all or any part of the preferred stock in each series at its option, or the preferred stock will be subject to mandatory redemption. The redemption price may be payable in cash or other property.

If the series of preferred stock is subject to mandatory redemption, then the prospectus supplement will specify:

•

the number of shares Duke Realty will redeem in each year;

•

the date after which Duke Realty may or must commence the redemption; and

•

the redemption price per share, which will include all accrued and unpaid dividends other than non-cumulative dividends for prior dividend periods.

Duke Realty will not redeem less than all of a series of preferred stock, or purchase or acquire any shares of a series of preferred stock, other than conversions or exchanges for common stock or other capital stock junior to the preferred stock, unless:

•

if the series of preferred stock has cumulative dividends, Duke Realty has declared and paid full cumulative dividends for all past and current dividend periods for this series or declared and reserved funds for payment; or

•

if the series of preferred stock does not have cumulative dividends, Duke Realty has declared and paid full dividends for the current dividend period or declared and reserved funds for payment.

Duke Realty may, however, purchase or acquire preferred stock of any series to preserve its status as a REIT, pursuant to an offer made on the same terms to all holders of preferred stock of that series or pursuant to open market purchases.

If Duke Realty redeems fewer than all outstanding shares of preferred stock of any series, it will determine the number of shares to be redeemed and whether it will redeem shares on a pro rata basis by shares held or shares requested to be redeemed or by lot in a manner determined by Duke Realty.

Duke Realty will mail redemption notices at least 30 days, but not more than 60 days, before the redemption date to each holder of record of a series of preferred stock to be redeemed at the address shown on the share transfer books. Each notice will state:

•

the redemption date;

•

the number of shares and series of the preferred stock to be redeemed;

•

the redemption price;

•

the place to surrender certificates for payment of the redemption price;

•

that dividends on the shares redeemed will cease to accumulate on the first calendar day after the redemption date; and

•

the date upon which any conversion rights will terminate.

If Duke Realty redeems fewer than all outstanding shares of a series of preferred stock, the notice also will specify the number of shares Duke Realty will redeem from each holder. If Duke Realty gives notice of redemption and has set aside sufficient funds necessary for the redemption in trust for the benefit of stock it will redeem, then Dividends will cease to accumulate on the first calendar day after the redemption date and all rights of the holders of the shares will terminate on the redemption date, except the right to receive the redemption price. If the board of directors declares a dividend payable after the redemption date with a record date prior to or on the redemption date, such dividend shall only accumulate up to and including the redemption date.

Liquidation Preference

If Duke Realty liquidates, dissolves or winds up its affairs, then holders of each series of preferred stock will receive out of Duke Realty’s legally available assets a liquidating distribution in the amount of the liquidation preference per share for that series as specified in the prospectus supplement, plus an amount equal to all dividends accrued and unpaid, but not including amounts from prior periods for non-cumulative dividends, before Duke Realty makes any distributions to holders of its common stock or any other capital stock ranking junior to the preferred stock. Once holders of outstanding preferred stock receive their respective liquidating distributions, they will have no right or claim to any of Duke Realty’s remaining assets. In the event that Duke Realty’s assets are not sufficient to pay the full liquidating distributions to the holders of all outstanding preferred stock and all other classes or series of its capital stock ranking on a parity with its preferred stock, then Duke Realty will distribute its assets to those holders in proportion to the full liquidating distributions to which they would otherwise have received.

After Duke Realty has paid liquidating distributions in full to all holders of its preferred stock, it will distribute its remaining assets among holders of any other capital stock ranking junior to the preferred stock according to their respective rights and preferences and number of shares. For this purpose, a consolidation or merger of Duke Realty with any other corporation or entity, or a sale, lease or conveyance of all or substantially all of Duke Realty’s property or business, does not constitute a liquidation, dissolution or winding up of Duke Realty’s affairs.

Voting Rights

Holders of preferred stock will not have any voting rights, except as set forth below or in the prospectus supplement or as otherwise required by law.

Whenever Duke Realty has not paid dividends on any shares of preferred stock for six or more quarterly periods, the holders of such shares may vote, separately as a class with all other series of preferred stock on which Duke Realty has not paid dividends, for the election of two additional directors of Duke Realty. In this event, Duke Realty’s board of directors will be increased by two directors. The holders of record of at least 10% of any series of preferred stock on which Duke Realty has not paid dividends may call a special meeting to elect these additional directors unless Duke Realty receives the request less than 90 days before the date of the next annual or special meeting of shareholders. Whether or not the holders call a special meeting, the holders of a series of preferred stock on which Duke Realty has not paid dividends may vote for the additional directors at the next annual meeting of shareholders and at each subsequent annual meeting until:

•

if the series of preferred stock has a cumulative dividend, Duke Realty has fully paid all unpaid dividends on the shares for the past dividend periods and the then current dividend period, or Duke Realty has declared the unpaid dividends and set apart a sufficient sum for their payment; or

•

if the series of preferred stock does not have a cumulative dividend, Duke Realty has fully paid four consecutive quarterly dividends, or Duke Realty has declared the dividends and set apart a sufficient sum for their payment.

Unless the prospectus supplement provides otherwise, Duke Realty cannot take any of the following actions without the affirmative vote of holders of at least two-thirds of the outstanding shares of each series of preferred stock:

•

authorize, create or increase the authorized or issued amount of any class or series of capital stock ranking senior to the series of preferred stock as to dividends or liquidation distributions;

•

reclassify any authorized capital stock into shares ranking senior to the series of preferred stock as to dividends or liquidation distributions;

•

issue any obligation or security convertible into or evidencing the right to purchase any share ranking senior to the series of preferred stock as to dividends or liquidation distributions; or

•

amend, alter or repeal any provision of Duke Realty’s articles of incorporation, whether by merger, consolidation or other event, in a manner that materially and adversely affects any right, preference, privilege or voting power of the preferred stock.

For these purposes, the following events do not materially and adversely affect a series of preferred stock:

•

an increase in the amount of the authorized shares of preferred stock;

•

the creation or issuance of any other series of preferred stock; or

•

an increase in the amount of authorized shares of the series of preferred stock or any other series of preferred stock ranking the same as or junior to such series as to dividends and liquidation distributions.

The holders of a series of preferred stock will have no voting rights, however, if Duke Realty redeems or calls for redemption all outstanding shares of the series and deposits sufficient funds in a trust to effect the redemption on or before the time the act occurs requiring the vote.

Under Indiana law, holders of each series of preferred stock are entitled to vote as a class upon any proposed amendment to Duke Realty’s articles of incorporation, if the amendment would:

•

increase or decrease the aggregate number of authorized shares of such series;

•

effect an exchange or reclassification of all or part of the shares of the series into shares of another series;

•

effect an exchange or reclassification or create the right of exchange of all or part of the shares of another class or series into shares of the series;

•

change the designation, rights, preferences or limitations of all or a part of the shares of the series;

•

change the shares of all or part of the series into a different number of shares of the same series;

•

create a new series having rights or preferences with respect to distributions or dissolution that are prior, superior or substantially equal to the shares of the series;

•

increase the rights, preferences or number of authorized shares of any class or series that, after giving effect to the amendment, have rights or preferences with respect to distributions or to dissolution that are prior, superior or substantially equal to the shares of the series;

•

limit or deny an existing preemptive right of all or part of the shares of the series; or

•

cancel or otherwise affect rights to distributions or dividends that have accumulated but have not yet been declared on all or part of the shares of the series.

Conversion Rights

If any series of preferred stock is convertible into common stock, the prospectus supplement will describe the following terms:

•

the number of shares of common stock into which the shares of preferred stock are convertible;

•

the conversion price or manner by which Duke Realty will calculate the conversion price;

•

the conversion period;

•

whether conversion will be at the option of the holders of the preferred stock or Duke Realty;

•

any events requiring an adjustment of the conversion price; and

•

provisions affecting conversion in the event of the redemption of the series of preferred stock.

Shareholder Liability

Indiana law provides that no shareholder, including holders of preferred stock, will be personally liable for Duke Realty’s acts and obligations except that a shareholder may become personally liable by reason of the shareholder’s own acts or conduct.

Change of Control Provisions

As discussed below under “Description of Common Stock – Change of Control Provisions,” Duke Realty’s articles of incorporation contain provisions which may discourage certain types of transactions involving an actual or threatened change of control.

Restrictions on Ownership

As discussed below under “Description of Common Stock – Restrictions on Ownership,” for Duke Realty to qualify as a REIT, not more than 50% in value of its outstanding capital stock may be owned, directly or indirectly, by five or fewer individuals during the last half of a taxable year. As a result, Duke Realty’s articles of incorporation provide generally for certain restrictions on transfer of Duke Realty’s issued and outstanding capital stock. The amendment to Duke Realty’s articles of incorporation designating the terms of each series of preferred stock may contain additional provisions restricting the ownership and transfer of the preferred stock. The prospectus supplement will specify any additional ownership limitation relating to a series of preferred stock.

Limitations of Liability and Indemnification of Directors and Officers

Indiana law and Duke Realty’s articles of incorporation generally exculpate each director and officer in actions by Duke Realty or by its shareholders in derivative actions from liability, except as described below under “Description of Common Stock — Limitation of Liability and Indemnification of Directors and Officers.”

Transfer Agent

The prospectus supplement will identify the transfer agent for the preferred stock.

DESCRIPTION OF DEPOSITARY SHARES

General

Duke Realty may issue depositary shares, each of which would represent a fractional interest of a share of a particular series of preferred stock. Duke Realty will deposit shares of preferred stock represented by depositary shares under a separate deposit agreement among Duke Realty, a preferred stock depositary and the holders of the depositary shares. Subject to the terms of the deposit agreement, each owner of a depositary share will possess, in proportion to the fractional interest of a share of preferred stock represented by the depositary share, all the rights and preferences of the preferred stock represented by the depositary shares.

Depositary receipts will evidence the depositary shares issued pursuant to the deposit agreement. Immediately after Duke Realty issues and delivers preferred stock to a preferred stock depositary, the preferred stock depositary will issue the depositary receipts.

Dividends and Other Distributions

The depositary will distribute all cash dividends on the preferred stock to the record holders of the depositary shares. Holders of depositary shares generally must file proofs, certificates and other information and pay charges and expenses of the depositary in connection with distributions.

If a distribution on the preferred stock is other than in cash and it is feasible for the depositary to distribute the property it receives, the depositary will distribute the property to the record holders of the depositary shares. If such a distribution is not feasible, the depositary, with Duke Realty’s approval, may sell the property and distribute the net proceeds from the sale to the holders of the depositary shares.

Withdrawal of Stock

Unless Duke Realty has previously called the underlying preferred stock for redemption or the holder of the depositary shares has converted such shares, a holder of depositary shares may surrender them at the corporate trust office of the depositary in exchange for whole or fractional shares of the underlying preferred stock together with any money or other property represented by the depositary shares. Once a holder has exchanged the depositary shares, the holder may not redeposit the preferred stock and receive depositary shares again. If a depositary receipt presented for exchange into preferred stock represents more shares of preferred stock than the number to be withdrawn, the depositary will deliver a new depositary receipt for the excess number of depositary shares.

Redemption of Depositary Shares

Whenever Duke Realty redeems shares of preferred stock held by a depositary, the depositary will redeem the corresponding amount of depositary shares with funds it receives from Duke Realty for the preferred stock. The depositary will notify the record holders of the depositary shares to be redeemed not less than 30 days nor more than 60 days before the dated fixed for redemption at the holders’ addresses appearing in the depositary’s books. The redemption price per depositary share will be equal to the applicable fraction of the redemption price and any other amounts payable with respect to the preferred stock. If Duke Realty intends to redeem less than all of the underlying preferred stock, Duke Realty and the depositary will select the depositary shares to be redeemed on as nearly a pro rata basis as practicable without creating fractional depositary shares or by any other equitable method determined by Duke Realty that preserves its REIT status. All dividends relating to the shares of preferred stock called for redemption will cease to accrue on the first calendar day after the redemption date.

On the redemption date:

•

Duke Realty and the depositary will no longer deem the depositary shares called for redemption to be outstanding; and

•

all rights of the holders of the depositary shares called for redemption will cease, except the right to receive any money payable upon the redemption and any money or other property to which the holders of the depositary shares are entitled upon redemption.

Voting of the Preferred Stock

When a depositary receives notice regarding a meeting at which the holders of the underlying preferred stock have the right to vote, it will mail that information to the holders of the depositary shares. Each record holder of depositary shares on the record date may then instruct the depositary to exercise its voting rights for the amount of preferred stock represented by that holder’s depositary shares. The depositary will vote in accordance with these instructions. The depositary will abstain from voting to the extent it does not receive specific instructions from the holders of depositary shares. A depositary will not be responsible for any failure to carry out any instruction to vote, or for the manner or effect of any vote, as long as any action or non-action is in good faith and does not result from negligence or willful misconduct of the depositary.

Liquidation Preference

In the event of Duke Realty’s liquidation, dissolution or winding up, a holder of depositary shares will receive the fraction of the liquidation preference accorded each share of underlying preferred stock represented by the depositary share.

Conversion of Preferred Stock

Depositary shares will not themselves be convertible into common stock or any other securities or property of Duke Realty. However, if the underlying preferred stock is convertible, holders of depositary shares may surrender them to the depositary with written instructions to convert the preferred stock represented by their depositary shares into whole shares of common stock, other shares of Duke Realty’s preferred stock or other shares of stock, as applicable. Upon receipt of these instructions and any amounts payable in connection with a conversion, Duke Realty will convert the preferred stock using the same procedures as those provided for delivery of preferred stock. If a holder of depositary shares converts only part of its depositary shares, the depositary will issue a new depositary receipt for any depositary shares not converted. Duke Realty will not issue fractional shares of common stock upon conversion. If a conversion will result in the issuance of a fractional share, Duke Realty will pay an amount in cash equal to the value of the fractional interest based upon the closing price of the common stock on the last business day prior to the conversion.

Amendment and Termination of a Deposit Agreement

Duke Realty and the depositary may amend any form of depositary receipt evidencing depositary shares and any provision of a deposit agreement. However, unless the existing holders of at least two-thirds of the applicable depositary shares then outstanding have approved the amendment, Duke Realty and the depositary may not make any amendment that:

•

would materially and adversely alter the rights of the holders of depositary shares; or

•

would be materially and adversely inconsistent with the rights granted to the holders of the underlying preferred stock.

Subject to exceptions in the deposit agreement and except in order to comply with the law, no amendment may impair the right of any holders of depositary shares to surrender their depositary shares with instructions to deliver the underlying preferred stock and all money and other property represented by the depositary shares. Every holder of outstanding depositary shares at the time any amendment becomes effective who continues to hold the depositary shares will be deemed to consent and agree to the amendment and to be bound by the amended deposit agreement.

Duke Realty may terminate a deposit agreement upon not less than 30 days’ prior written notice to the depositary if:

•

the termination is necessary to preserve Duke Realty’s REIT status; or

•

a majority of each series of preferred stock affected by the termination consents to the termination.

Upon a termination of a deposit agreement, holders of the depositary shares may surrender their depositary shares and receive in exchange the number of whole or fractional shares of preferred stock and any other property represented by the depositary shares. If Duke Realty terminates a deposit agreement to preserve its status as a REIT, then Duke Realty will use its best efforts to list the preferred stock issued upon surrender of the related depositary shares on a national securities exchange.

In addition, a deposit agreement will automatically terminate if:

•

Duke Realty has redeemed all underlying preferred stock subject to the agreement;

•

a final distribution of the underlying preferred stock in connection with any liquidation, dissolution or winding up has occurred, and the depositary has distributed the distribution to the holders of the depositary shares; or

•

each share of the underlying preferred stock has been converted into other capital stock of Duke Realty not represented by depositary shares.

Expenses of a Preferred Stock Depositary

Duke Realty will pay all transfer and other taxes and governmental charges and expenses arising in connection with a deposit agreement. In addition, Duke Realty will generally pay the fees and expenses of a depositary in connection with the performance of its duties. However, holders of depositary shares will pay the fees and expenses of a depositary for any duties requested by the holders that the deposit agreement does not expressly require the depositary to perform.

Resignation and Removal of Depositary

A depositary may resign at any time by delivering to Duke Realty notice of its election to resign. Duke Realty may also remove a depositary at any time. Any resignation or removal will take effect upon the appointment of a successor depositary. Duke Realty will appoint a successor depositary within 60 days after delivery of the notice of resignation or removal. The successor must be a bank or trust company with its principal office in the United States and have a combined capital and surplus of at least $50 million.

Miscellaneous

The depositary will forward to the holders of depositary shares any reports and communications from Duke Realty with respect to the underlying preferred stock.

Neither the depositary nor Duke Realty will be liable if any law or any circumstances beyond their control prevent or delay them from performing their obligations under a deposit agreement. The obligations of Duke Realty and a depositary under a deposit agreement will be limited to performing their duties in good faith and without negligence in regard to voting of preferred stock, gross negligence or willful misconduct. Neither Duke Realty nor a depositary must prosecute or defend any legal proceeding with respect to any depositary shares or the underlying preferred stock unless they are furnished with satisfactory indemnity.

Duke Realty and any depositary may rely on the written advice of counsel or accountants, or information provided by persons presenting shares of preferred stock for deposit, holders of depositary shares or other persons they believe in good faith to be competent, and on documents they believe in good faith to be genuine and signed by a proper party.

In the event a depositary receives conflicting claims, requests or instructions from Duke Realty and any holders of depositary shares, the depositary will be entitled to act on the claims, requests or instructions received from Duke Realty.

Depositary

The prospectus supplement will identify the depositary for the depositary shares.

Listing of the Depositary Shares

The applicable prospectus supplement will specify whether or not the depositary shares will be listed on any securities exchange.

DESCRIPTION OF COMMON STOCK

The following description of shares of our common stock, par value $.01 per share, is a summary only and is subject to applicable provisions of the Indiana Business Corporation Law and to our articles of incorporation and bylaws. You should refer to, and read this summary together with, our articles of incorporation and bylaws to review all of the terms of our common stock.

General

Duke Realty’s authorized capital stock includes 400 million shares of common stock, $.01 par value per share. Each outstanding share of common stock entitles the holder to one vote on all matters presented to shareholders for a vote. Holders of common stock have no preemptive rights.

Holders of common stock have no right to cumulative voting for the election of directors. Consequently, because each member of Duke Realty’s board of directors serves only a one-year term, a majority of the shareholders present in person or represented by proxy and entitled to vote are able to elect all of the directors at each annual shareholders’ meeting.

Duke Realty’s shares of common stock currently outstanding are listed on the New York Stock Exchange under the symbol “DRE.” Duke Realty will apply to the New York Stock Exchange to list additional shares of common stock to be sold pursuant to any prospectus supplement, and Duke Realty anticipates that any such shares will be listed on the New York Stock Exchange.

All shares of common stock issued will be duly authorized and issued, fully paid, and non-assessable. Distributions may be paid to the holders of common stock if and when declared by Duke Realty’s board of directors out of funds legally available for such distributions. Duke Realty intends to continue to pay quarterly dividends.

Duke Realty’s shareholders are entitled to share ratably in its assets legally available for distribution to shareholders in the event of its liquidation, dissolution or winding up, voluntarily or involuntarily, after payment of, or adequate provision for, all of its known debts and liabilities. These rights are subject to the preferential rights of any other class or series of Duke Realty’s stock that may then be outstanding and to the provisions of its articles of incorporation regarding restrictions on transfer of Duke Realty stock to preserve its status as a REIT for federal income tax purposes.

Holders of Duke Realty’s shares of common stock have no preference, conversion, exchange, sinking fund or redemption rights and have no preemptive rights to subscribe for any of Duke Realty’s securities. Duke Realty’s board of directors may issue additional shares of common stock without the approval of Duke Realty’s shareholders.

Under Indiana law, shareholders are generally not liable for Duke Realty’s debts or obligations. If Duke Realty is liquidated, after payment or provision for all of Duke Realty’s known debts and liabilities and any preferential distributions required to be made to holders of preferred stock, each outstanding share of common stock will be entitled to participate on a pro rata basis in the remaining assets.

Dividends

Holders of Duke Realty’s shares of common stock are entitled to receive dividends only when, as and if approved by Duke Realty’s board of directors out of assets legally available for the payment of dividends. Please see “Federal Income Tax Considerations — Taxation of U.S. Shareholders” for a description of the tax effect of dividends and distributions to Duke Realty’s shareholders, and the dividend requirements that Duke Realty must satisfy to maintain its status as a REIT.

Change of Control Provisions

Under Indiana law, shareholders holding a majority of the shares voting must approve any transaction pursuant to which Duke Realty would merge with another entity or would sell all or substantially all of its assets. Duke Realty’s articles of incorporation also contain provisions which may discourage certain types of transactions involving an actual or threatened change of control, including:

•

a requirement that certain mergers, sales of assets, liquidations or dissolutions, or reclassifications or recapitalizations involving persons owning 10% or more of Duke Realty’s capital stock:

•

be approved by a vote of the holders of 80% of the issued and outstanding shares of Duke Realty’s capital stock;

•

be approved by three-fourths of the continuing directors; or

•

provide for payment to shareholders for their shares of at least a specified price;

•

a requirement that any amendment or alteration of certain provisions of the articles of incorporation affecting change of control be approved by the holders of 80% of Duke Realty’s issued and outstanding capital stock; and

•

a limitation that directors may be removed only for “cause” and only with the affirmative vote of at least a majority of the total votes eligible to be cast by shareholders at a duly constituted meeting of shareholders called expressly for such purpose.

The partnership agreement for the Operating Partnership also contains provisions that could discourage transactions involving an actual or threatened change of control of Duke Realty, including:

•

a requirement that holders of at least 90% of the outstanding partnership units held by Duke Realty and other unit holders approve any voluntary sale, exchange, merger, consolidation or other disposition of all or substantially all of the assets of the Operating Partnership in one or more transactions other than a disposition occurring upon a financing or refinancing of the Operating Partnership;

•

a restriction against any assignment or transfer by Duke Realty of its interest in the Operating Partnership; and

•

a requirement that holders of more than 90% of the partnership units approve:

•

any merger, consolidation or other combination of Duke Realty with another entity, unless after the transaction substantially all of the assets of the surviving entity are contributed to the Operating Partnership in exchange for units;

•

any sale of all or substantially all of Duke Realty’s assets; or

•

any reclassification or recapitalization or change of outstanding shares of common stock other than certain changes in par value, stock splits, stock dividends or combinations.

Duke Realty’s directors who are not officers or employees and who do not hold partnership units will vote on these matters.

Restrictions on Ownership

For Duke Realty to qualify as a REIT under the Internal Revenue Code:

•

no more than 50% in value of Duke Realty’s outstanding stock may be owned, directly or indirectly, by five or fewer individuals (including certain entities) at any time during the last half of a taxable year; and

•

Duke Realty’s stock must be beneficially owned by 100 or more persons during at least 335 days of each taxable year or during a proportionate part of a shorter taxable year.

Because Duke Realty expects to continue to qualify as a REIT, its articles of incorporation contain restrictions on the acquisition of common stock intended to ensure compliance with these requirements. Specifically, Duke Realty’s articles of incorporation contain restrictions that:

•

authorize but do not require Duke Realty’s board of directors to refuse to give effect to a transfer of common stock which, in its opinion, might jeopardize the status of Duke Realty as a REIT;

•

nullify any attempted acquisition of shares which would result in the disqualification of Duke Realty as a REIT;

•

give the board of directors the authority to take any actions it deems advisable to enforce the restrictions, which might include refusing to give effect to or seeking to enjoin a transfer which might jeopardize Duke Realty’s status as a REIT; and

•

require any shareholder to provide Duke Realty such information regarding his or her direct and indirect ownership of common stock as Duke Realty may reasonably require.

Limitations of Liability and Indemnification of Directors and Officers

•

any breach of the director’s duty of loyalty to Duke Realty or its shareholders;

•

acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

•

voting for or assenting to an unlawful distribution; or

•

any transaction from which the director derived an improper personal benefit.

The articles of incorporation also provide that Duke Realty will indemnify a present or former director or officer against expense or liability in an action to the fullest extent permitted by Indiana law. Indiana law permits a corporation to indemnify its present and former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses they incur in connection with any proceeding to which they are a party, so long as:

•

the individual’s conduct was in good faith;

•

the individual reasonably believed, in the case of conduct in the individual’s official capacity with the corporation, that the conduct was in the corporation’s best interests and, in all other cases, that the individual’s conduct was at least not opposed to the corporation’s best interests; and

•

in the case of a criminal proceeding, the individual either had reasonable cause to believe the individual’s conduct was lawful or had no reasonable cause to believe the individual’s conduct was unlawful.

We believe that the exculpation and indemnification provisions in Duke Realty’s articles of incorporation help induce qualified individuals to agree to serve as officers and directors of Duke Realty by providing a degree of protection from liability for alleged mistakes in making decisions and taking actions. You should be aware, however, that these provisions in Duke Realty’s articles of incorporation and Indiana law give you a more limited right of action than you otherwise would have in the absence of such provisions. Duke Realty also maintains a policy of directors and officers liability insurance covering certain liabilities incurred by Duke Realty’s directors and officers in connection with the performance of their duties.

The above indemnification provisions could operate to indemnify directors, officers or other persons who exert control over Duke Realty against liabilities arising under the Securities Act. Insofar as the above provisions may allow that type of indemnification, the SEC has informed us that, in its opinion, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

Shareholder Liability

Indiana law provides that no shareholder, including holders of common stock, will be personally liable for Duke Realty’s acts and obligations except that a shareholder may become personally liable by reason of the shareholder’s own acts or conduct.

Registrar and Transfer Agent

The registrar and transfer agent for the common stock is American Stock Transfer & Trust Company, New York, New York.

DESCRIPTION OF WARRANTS

General

Duke Realty may issue warrants to purchase preferred stock, depositary shares, common stock or any combination of these securities, and these warrants may be issued independently or together with any underlying securities and may be attached to or separate from the underlying securities. Duke Realty will issue each series of warrants under a separate warrant agreement to be entered into between us and a warrant agent. The warrant agent will act solely as our agent in connection with the warrants of such series and will not assume any obligation or relationship of agency for or on behalf of holders or beneficial owners of warrants. The following outlines some of the general terms and provisions of the warrants. Further terms of the warrants and the applicable warrant agreement will be stated in the applicable prospectus supplement. The following description and any description of the warrants in a prospectus supplement may not be complete and is subject to and qualified in its entirety by reference to the terms and provisions of the warrant agreement, which we will file with the SEC in connection with an issuance of the warrants.

The applicable prospectus supplement will describe the terms of any warrants, including the following:

•

the title of the warrants;

•

the total number of warrants;

•

the price or prices at which we will issue the warrants;

•

any applicable anti-dilution provisions to adjust the number of shares to be delivered upon exercise of warrants to purchase common stock;

•

the currency or currencies investors may use to pay for the warrants;

•

the designation and terms of the underlying securities purchasable upon exercise of the warrants;

•

the price at which and the currency or currencies, including composite currencies, in which investors may purchase the underlying securities purchasable upon exercise of the warrants, as well as related adjustment provisions affecting that exercise price;

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

Warrant certificates may be exchanged for new warrant certificates of different denominations, and warrants may be exercised at the warrant agent’s corporate trust office or any other office indicated in the applicable prospectus supplement. Prior to the exercise of their warrants, holders of warrants exercisable for debt securities will not have any of the rights of holders of the debt securities purchasable upon such exercise and will not be entitled to payments of principal (or premium, if any) or interest, if any, on the debt securities purchasable upon such exercise. Prior to the exercise of their warrants, holders of warrants exercisable for shares of preferred stock, common stock or for depositary shares will not have any rights of holders of the preferred stock, common stock or depositary shares purchasable upon such exercise and will not be entitled to dividend payments, if any, or voting rights of the preferred stock, common stock or depositary shares purchasable upon such exercise.

Exercise of Warrants

A warrant will entitle the holder to purchase for cash an amount of securities at an exercise price that will be stated in, or that will be determinable as described in, the applicable prospectus supplement. Warrants may be exercised at any time up to the close of business on the expiration date set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

Warrants may be exercised as set forth in the applicable prospectus supplement. Upon receipt of payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement, we will, as soon as practicable, forward the securities purchasable upon such exercise. If less than all of the warrants represented by such warrant certificate are exercised, a new warrant certificate will be issued for the remaining warrants.

Enforceability of Rights; Governing Law

The holders of warrants, without the consent of the warrant agent, may, on their own behalf and for their own benefit, enforce, and may institute and maintain any suit, action or proceeding against us to enforce their rights to exercise and receive the securities purchasable upon exercise of their warrants. Unless otherwise stated in the applicable prospectus supplement, each issue of warrants and the applicable warrant agreement will be governed by the laws of the State of Indiana.

DESCRIPTION OF STOCK PURCHASE CONTRACTS

Duke Realty may issue stock purchase contracts, representing contracts obligating holders to purchase from or sell to it, and obligating it to purchase from or sell to the holders, a specified or variable number of shares of Duke Realty’s capital stock at a future date or dates. The price per share of capital stock may be fixed at the time the stock purchase contracts are entered into or may be determined by reference to a specific formula contained in the stock purchase contracts. Any stock purchase contract may include anti-dilution provisions to adjust the number of shares to be delivered pursuant to such stock purchase contract upon the occurrence of certain events. Duke Realty may issue the stock purchase contracts in such amounts and in as many distinct series as we wish.

The stock purchase contracts may be entered into separately or as a part of units consisting of a stock purchase contract and a beneficial interest in debt securities, debt obligations of third parties, including U.S. Treasury securities, other stock purchase contracts or shares of our capital stock securing the holders’ obligations under the stock purchase contracts to purchase or to sell the shares of our capital stock. The stock purchase contracts may require Duke Realty to make periodic payments to holders hereunder and such payments may be unsecured or prefunded and may be paid on a current or on a deferred basis. The stock purchase contracts may require holders to secure their obligations under those contracts in a specified manner. The applicable prospectus supplement may contain, where applicable, the following information about the stock purchase contracts issued under it:

•

whether the stock purchase contracts obligate the holder to purchase or sell, or both purchase and sell, Duke Realty’s common stock or preferred stock or depositary shares, as applicable, and the nature and amount of each of those securities, or the method of determining those amounts;

•

whether the stock purchase contracts are to be prepaid or not;

•

whether the stock purchase contracts are to be settled by delivery, or by reference or linkage to the value, performance or level of our common stock or preferred stock or depositary shares;

•

any acceleration, cancellation, termination or other provisions relating to the settlement of the stock purchase contracts; and

•

whether the stock purchase contracts will be issued in fully registered or global form.

The applicable prospectus supplement will describe the specific terms of any stock purchase contracts. The preceding description and any description of stock purchase contracts in the applicable prospectus supplement is a general summary and is subject to and is qualified in its entirety by reference to the stock purchase contract agreement and, if applicable, collateral arrangements and depositary arrangements relating to such stock purchase contracts.

DESCRIPTION OF UNITS

Duke Realty may issue units comprised of one or more of the securities described in this prospectus in any combination. Units may also include debt obligations of third parties, such as debt securities of the Operating Partnership or U.S. Treasury securities. Each unit will be issued so that the holder of the unit also is the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately at any time or at any time before a specified date.

The applicable prospectus supplement may describe, among other things:

•

the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

•

any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units; and

•

whether the units will be issued in fully registered or global form.

The applicable prospectus supplement will describe the terms of any units and the securities comprising those units. The preceding description and any description of units in the applicable prospectus supplement is a summary and is subject to, and is qualified in its entirety by, reference to the unit agreement and, if applicable, collateral arrangements and depositary arrangements relating to such units.

FEDERAL INCOME TAX CONSIDERATIONS

The following discussion summarizes the material federal income tax consequences relating to the taxation of us as a REIT and to the purchase, ownership and disposition of our common stock.

If we offer one or more additional series of preferred stock or the Operating Partnership offers one or more additional series of debt securities, the prospectus supplement will include information about any additional material federal income tax consequences to holders of those shares of preferred stock or debt securities.

Because this summary is intended only to address material federal income tax consequences relating to the ownership and disposition of our common stock, it may not contain all the information that may be important to you. As you review this discussion, you should keep in mind that:

•

the tax consequences to you may vary depending upon your particular tax situation;

•

special rules that we do not discuss below may apply if, for example, you are a tax-exempt organization, a broker-dealer, a non-U.S. person, a trust, an estate, a regulated investment company, a financial institution, an insurance company or otherwise subject to special tax treatment under the Internal Revenue Code;

•

this summary generally does not address state, local or non-U.S. tax considerations;

•

this summary deals only with shareholders that hold our stock as “capital assets” within the meaning of Section 1221 of the Internal Revenue Code; and

•

we do not intend this discussion to be, and you should not construe it as, tax advice.

You should review the following discussion and consult with your own tax advisor to determine the effect of ownership and disposition of our stock on your individual tax situation, including any state, local or non-U.S. tax consequences.

We base the information in this section on the current Internal Revenue Code, current final, temporary and proposed Treasury regulations, the legislative history of the Internal Revenue Code, current administrative interpretations and practices of the IRS, including its practices and policies as endorsed in private letter rulings, which are not binding on the IRS, and existing court decisions. Future legislation, regulations, administrative interpretations and court decisions could change current law or adversely affect existing interpretations of current law. Any change could apply retroactively. It is possible that the IRS could challenge the statements in this discussion, which do not bind the IRS or the courts, and that a court could agree with the IRS.

Taxation of Our Company as a REIT

We believe that, commencing with our taxable year ended December 31, 1986, we have been organized and have operated in such a manner as to qualify for taxation as a REIT under the Internal Revenue Code, and we intend to continue to be organized and to operate in such a manner. However, we cannot assure you that we have operated or will operate in a manner so as to qualify or remain qualified as a REIT. This section discusses the laws governing the federal income tax treatment of a REIT and its shareholders. These laws are highly technical and complex.

Federal Income Taxation of Our Company

If we have qualified and continue to qualify for taxation as a REIT, we generally will not be subject to federal corporate income tax on that portion of our ordinary income or capital gain that is timely distributed to shareholders. The REIT provisions of the Internal Revenue Code generally allow a REIT to deduct distributions paid to its shareholders, substantially eliminating the federal “double taxation” on earnings (once at the corporate level when earned and once again at the shareholder level when distributed) that usually results from investments in a corporation. Nevertheless, we will be subject to federal income tax as follows:

First, we will be taxed at regular corporate rates on our undistributed “REIT taxable income,” including undistributed net capital gains.

Second, under some circumstances, we may be subject to the “alternative minimum tax” as a consequence of our items of tax preference.

Third, if we have net income from the sale or other disposition of “foreclosure property” that we hold primarily for sale to customers in the ordinary course of business or other non-qualifying income from foreclosure property, we will be subject to tax at the highest corporate rate on such income.

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

Fifth, if we should fail to satisfy either the 75% gross income test or the 95% gross income test (discussed below) but have nonetheless maintained our qualification as a REIT because we have met other requirements, we will be subject to a 100% tax on the greater of the amount by which the 75% gross income test was not satisfied or the amount by which the 95% gross income test was not satisfied, in each case, multiplied by a fraction intended to reflect our profitability.

Sixth, if we fail to satisfy any of the asset tests (described below) or any of the REIT qualification requirements other than the gross income and asset tests and such failure is due to reasonable cause, we may avoid disqualification as a REIT by, among other things, paying a penalty of $50,000 or more in certain cases.

Seventh, if we fail to distribute during each year at least the sum of

•

85% of our ordinary income for such year,

•

95% of our capital gain net income for such year, and

•

any undistributed taxable income from prior periods,

then we will be subject to a 4% excise tax on the excess of this required distribution amount over the amounts actually distributed.

Eighth, if we should acquire any asset from a “C” corporation (i.e., a corporation generally subject to full corporate-level tax) in a carryover-basis transaction and provided no election is made for the transaction to be currently taxable, and we subsequently recognize gain on the disposition of such asset during the 10-year period beginning on the date on which we acquired the asset, we generally will be subject to tax at the highest regular corporate rate on the lesser of the amount of gain that we recognize at the time of the sale or disposition and the amount of gain that we would have recognized if we had sold the asset at the time we acquired the asset, the “Built-in Gains Tax.”

We own direct or indirect interests in a number of taxable REIT subsidiaries, such as Duke Realty Construction, Inc. Our “taxable REIT subsidiaries” are corporations in which Duke Realty directly or indirectly owns stock and that elect, together with us, to be treated as our taxable REIT subsidiaries. In addition, if one of our taxable REIT subsidiaries owns, directly or indirectly, securities representing 35% or more of the vote or value of a subsidiary corporation, that subsidiary will also be treated as our taxable REIT subsidiary. A taxable REIT subsidiary is subject to federal income tax, and state and local income tax where applicable, as a regular “C” corporation.

Generally, a taxable REIT subsidiary may perform certain tenant services without causing us to receive impermissible tenant services income under the REIT income tests. However, several provisions regarding the arrangements between a REIT and its taxable REIT subsidiaries ensure that a taxable REIT subsidiary will be subject to an appropriate level of federal income taxation. For example, the Internal Revenue Code limits the ability of a taxable REIT subsidiary to deduct interest payments in excess of a certain amount made to us. In addition, we must pay a 100% tax on some payments that we receive or on certain expenses deducted by the taxable REIT subsidiary if the economic arrangements between us, our tenants, and the taxable REIT subsidiary

are not comparable to similar arrangements among unrelated parties. Our taxable REIT subsidiaries make interest and other payments to Duke Realty and to third parties in connection with activities related to our properties. We cannot assure you that our taxable REIT subsidiaries will not be limited in their ability to deduct interest payments made to us. In addition, we cannot assure you that the IRS might not seek to impose the 100% tax on services performed by taxable REIT subsidiaries for our tenants, or on a portion of the payments received by us from, or expenses deducted by, our taxable REIT subsidiaries.

As noted above, we are subject to a 100% penalty tax on income from prohibited transactions (generally, income derived from the sale of property primarily held for sale to customers in the ordinary course of business). The Internal Revenue Code provides a safe harbor that, if met, allows us to avoid being treated as engaged in a prohibited transaction. In order to meet the safe harbor, among other things, (i) we must have held the property for at least 2 years (and, in the case of property which consists of land or improvements not acquired through foreclosure, we must have held the property for 2 years for the production of rental income) and (ii) during the taxable year the property is disposed of, we must not have made more than 7 property sales or, alternatively, the aggregate adjusted basis or fair market value of all of the properties sold by us during the taxable year must not exceed 10% of the aggregate adjusted basis or 10% of the fair market value, respectively, of all of our assets as of the beginning of the taxable year. Any foreign currency gain (as defined in Section 988(b)(1) of the Internal Revenue Code) and any foreign currency loss (as defined in Section 988(b)(2) of the Internal Revenue Code) will be taken into account in determining the amount of income subject to the 100% penalty tax.

Requirements For Qualification

To qualify as a REIT, we must elect to be treated as a REIT and must meet the requirements, discussed below, relating to our organization, sources of income, nature of assets and distributions.

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

•

that is managed by one or more trustees or directors;

•

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

•

that would be taxable as a domestic corporation but for application of the REIT rules;

•

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

•

that has at least 100 persons as beneficial owners;

•

during the last half of each taxable year, not more than 50% in value of the outstanding stock of which is owned, directly or indirectly, through the application of certain attribution rules, by five or fewer individuals (as defined in the Internal Revenue Code to include certain entities);

•

that files an election or continues such election to be taxed as a REIT on its return for each taxable year;

•

that uses the calendar year as its taxable year; and

•

that satisfies the income tests, the asset tests, and the distribution tests, described below.

The Internal Revenue Code provides that REITs must satisfy all of the first four preceding requirements during the entire taxable year. REITs must satisfy the fifth requirement 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. For purposes of the sixth requirement, the beneficiaries of a pension or profit-sharing trust described in Section 401(a) of the Internal Revenue Code, and not the pension or profit-sharing trust itself, are treated as REIT shareholders. We will be

treated as having met the sixth requirement if we comply with certain Treasury Regulations for ascertaining the ownership of our stock for such year and if we did not know (or after the exercise of reasonable diligence would not have known) that the sixth condition was not satisfied for such year. Our articles of incorporation currently include restrictions regarding transfer of our stock that assist us in continuing to satisfy the fifth and sixth of these requirements.

If a REIT owns a corporate subsidiary that is a “qualified REIT subsidiary,” the separate existence of that subsidiary will be disregarded for federal income tax purposes. Generally, a qualified REIT subsidiary is a corporation, other than a taxable REIT subsidiary, all of the capital stock of which is owned by the REIT. All assets, liabilities and items of income, deduction and credit of the qualified REIT subsidiary will be treated as assets, liabilities and items of income, deduction and credit of the REIT itself. Our qualified REIT subsidiaries will not be subject to federal corporate income taxation, although they may be subject to state and local taxation in some states.

A REIT that is a partner in a partnership is deemed to own its proportionate share of the assets of the partnership and to earn its proportionate share of the partnership’s income, in both cases being based on its relative capital interest in the partnership. The character of the assets and gross income of the partnership retain the same character in the hands of the REIT for purposes of the gross income and asset tests. Thus, our proportionate share of the assets, liabilities and items of income of the Operating Partnership (including the Operating Partnership’s share of the assets, liabilities and items of income with respect to any partnership in which it holds an interest) is treated as our assets, liabilities and items of income for purposes of applying the requirements described herein.

Income Tests. In order to maintain qualification as a REIT, we must satisfy two gross income requirements. First, we must derive, directly or indirectly, at least 75% of our gross income (excluding gross income from prohibited transactions) for each taxable year from investments relating to real property or mortgages on real property, including “rents from real property,” gains on disposition of real estate, dividends paid by another REIT and interest on obligations secured by real property or on interests in real property, or from certain types of temporary investments. Second, we must derive at least 95% of our gross income (excluding gross income from prohibited transactions) for each taxable year from any combination of income qualifying under the 75% test and dividends, interest and gain from the sale or disposition of stock or securities.

Any income from (i) a hedging transaction that is clearly and timely identified and that hedges indebtedness incurred or to be incurred to acquire or carry real estate assets or (ii) a clearly and timely identified transaction entered into primarily to manage the risk of currency fluctuations with respect to any item of income that would qualify under a 75% or the 95% gross income tests, will not constitute gross income (rather than being treated either as qualifying income or non-qualifying income) for purposes of the 75% and the 95% gross income tests. Income from such transactions that does not meet these requirements will be treated as non-qualifying income for purposes of the 75% and the 95% gross income tests. Any income from foreign currency gain that is “real estate foreign exchange gain” as defined in the Internal Revenue Code will not constitute gross income for purposes of the 75% gross income tests. “Real estate foreign exchange gain” includes foreign currency gains attributable to (i) any item of income or gain that would qualify under the 75% gross income test, (ii) the acquisition or ownership of obligations secured by mortgages on real property or interests in real property, (iii) becoming or being the obligor under obligations secured by mortgages on real property or on interests in real property, (iv) remittances from qualified business units that meet the 75% gross income test for the taxable year and the 75% asset test at the close of each quarter, and (v) any other foreign currency gain as determined by the Internal Revenue Service. Other foreign currency gain, if such currency gain is “passive foreign exchange gain” as defined in the Internal Revenue Code, will not constitute gross income for purposes of the 95% gross income test (but will be treated as income that does not qualify under the 75% gross income test). “Passive foreign exchange gain” includes foreign currency gains attributable to (i) real estate foreign exchange gain, (ii) any item of income or gain that would qualify under the 95% gross income test, (iii) the acquisition or ownership of obligations, (iv) becoming or being the obligor under the obligations, and (v) any other foreign currency gain as determined by the Internal Revenue Service.

Rents that we receive will qualify as “rents from real property” in satisfying the gross income requirements for a REIT described above only if several conditions are met. First, the amount of rent must not be based in whole or in part on the income or profits of any person but can be based on a fixed percentage of gross receipts or gross sales. Second, “rents from real property” generally excludes any amount received directly or indirectly from any tenant if we, or an owner of 10% of more of our outstanding stock, directly or constructively, own 10% or more of such tenant taking into consideration the applicable attribution rules, which we refer to as a “related party tenant.” Third, “rents from real property” excludes rent attributable to personal property except where such personal property is leased in connection with a lease of real property and the rent attributable to such personal property is less than or equal to 15% of the total rent received under the lease. Finally, amounts that are attributable to services furnished or rendered in connection with the rental of real property, whether or not separately stated, will not constitute “rents from real property” unless such services are customarily provided in the geographic area. Customary services that are not considered to be provided to a particular tenant (e.g., furnishing heat and light, the cleaning of public entrances, and the collection of trash) can be provided directly by us. Where, on the other hand, such services are provided primarily for the convenience of the tenants or are provided to such tenants, such services must be provided by an independent contractor from whom we do not receive any income or a taxable REIT subsidiary. Non-customary services that are not performed by an independent contractor or taxable REIT subsidiary in accordance with the applicable requirements will result in impermissible tenant service income to us to the extent of the income earned (or deemed earned) with respect to such services. If the impermissible tenant service income exceeds 1% of our total income from a property, all of the income from that property will fail to qualify as rents from real property. If the total amount of impermissible tenant services does not exceed 1% of our total income from the property, the services will not cause the rent paid by tenants of the property to fail to qualify as rents from real property, but the impermissible tenant services income will not qualify as “rents from real property.”

We do not currently charge and do not anticipate charging rent that is based in whole or in part on the income or profits of any person. We also do not anticipate either deriving rent attributable to personal property leased in connection with real property that exceeds 15% of the total rents or receiving rent from related party tenants.

The Operating Partnership does provide some services with respect to the properties. We believe that the services with respect to the properties that are and will be provided directly are usually or customarily rendered in connection with the rental of space for occupancy only and are not otherwise considered rendered to particular tenants and, therefore, that the provision of such services will not cause rents received with respect to the properties to fail to qualify as rents from real property. Services with respect to the properties that we believe may not be provided by us or the Operating Partnership directly without jeopardizing the qualification of rent as “rents from real property” are and will be performed by independent contractors or taxable REIT subsidiaries.

We, including the Operating Partnership, receive fees for property management and brokerage and leasing services provided with respect to some properties not owned entirely by the Operating Partnership. These fees, to the extent paid with respect to the portion of these properties not owned, directly or indirectly, by us, will not qualify under the 75% gross income test or the 95% gross income test. The Operating Partnership also may receive other types of income with respect to the properties it owns that will not qualify for either of these tests. We believe, however, that the aggregate amount of these fees and other non-qualifying income in any taxable year will not cause us to exceed the limits on non-qualifying income under either the 75% gross income test or the 95% gross income test.

If we fail to satisfy the 75% gross income test or the 95% gross income test for any taxable year, we may nevertheless qualify as a REIT for that year if we are eligible for relief under the Internal Revenue Code. This relief provision generally will be available if:

•

Our failure to meet these tests was due to reasonable cause and not due to willful neglect; and

•

We file a disclosure schedule with the IRS after we determine that we have not satisfied one of the gross income tests.

We cannot state whether in all circumstances we would be entitled to the benefit of this relief provision. For example, if we fail to satisfy the gross income tests because non-qualifying income that we intentionally incur exceeds the limits on such income, the IRS could conclude that our failure to satisfy the tests was not due to reasonable cause. Even if this relief provision applies, the Internal Revenue Code imposes a 100% tax with respect to a portion of the non-qualifying income, as described above.

Asset Tests. At the close of each quarter of our taxable year, we also must satisfy four tests relating to the nature and diversification of our assets:

•

At least 75% of the value of our total assets must be represented by real estate assets, cash and cash items (including receivables) and government securities.

•

No more than 25% of the value of our total assets may be represented by securities other than those in the 75% asset class.

•

Except for equity investments in REITs, qualified REIT subsidiaries or taxable REIT subsidiaries or other securities that qualify as “real estate assets” for purposes of the 75% asset test:

•

the value of any one issuer’s securities that we own may not exceed 5% of the value of our total assets;

•

we may not own more than 10% of any one issuer’s outstanding voting securities; and

•

we may not own more than 10% of the value of the outstanding securities of any one issuer.

•

No more than 25% of our total assets may be represented by securities of one or more taxable REIT subsidiaries.

Certain types of securities are disregarded as securities for purposes of the 10% value limitation discussed above including, (i) straight debt securities (including straight debt that provides for certain contingent payments); (ii) any loan to an individual or an estate; (iii) any rental agreement described in Section 467 of the Internal Revenue Code, other than with a “related person”; (iv) any obligation to pay rents from real property; (v) certain securities issued by a State or any political subdivision thereof, the District of Columbia, a foreign government, or any political subdivision thereof, or the Commonwealth of Puerto Rico; (vi) any security issued by a REIT; and (vii) any other arrangement that, as determined by the Secretary of the Treasury, is excepted from the definition of a security. In addition, (a) a REIT’s interest as a partner in a partnership is not considered a “security” for purposes of applying the 10% value test to securities issued by the partnership; (b) any debt instrument issued by a partnership (other than straight debt or other excluded security) will not be considered a security issued by the partnership if at least 75% of the partnership’s gross income is derived from sources that would qualify for the 75% gross income test, and (c) any debt instrument issued by a partnership (other than straight debt or other excluded security) will not be considered a security issued by the partnership to the extent of the REIT’s interest as a partner in the partnership. Special look-through rules for determining a REIT’s share of securities held by a partnership in which the REIT holds an interest.

We believe that the aggregate value of our securities issued by our taxable REIT subsidiaries does not exceed 25% of the aggregate value of our gross assets. With respect to each issuer in which we currently own an interest that does not qualify as a REIT, a qualified REIT subsidiary or a taxable REIT subsidiary, we believe that the value of the securities, including debt, of any such issuer owned (or treated as owned) by us does not exceed 5% of the total value of our assets and that we comply with the 10% voting securities limitation and 10% value limitation with respect to each such issuer. In this regard, however, we cannot provide any assurance that the IRS might not disagree with our determinations.

After initially meeting the asset tests at the close of any quarter, we will not lose our qualification as a REIT for failure to satisfy the asset tests at the end of a later quarter solely by reason of changes in asset values. If the failure to satisfy the asset tests results from an acquisition of securities or other property during a quarter, we can cure the

failure by disposing of a sufficient amount of non-qualifying assets within 30 days after the close of that quarter. We intend to maintain adequate records of the value of our assets to ensure compliance with the asset tests and to take such other actions within 30 days after the close of any quarter as necessary to cure any noncompliance.

After the 30-day cure period, a REIT may avoid disqualification as a REIT by disposing of sufficient assets to cure such a violation that does not exceed the lesser of 1% of the REIT’s assets at the end of the relevant quarter or $10,000,000, provided that the disposition occurs within six months following the last day of the quarter in which the REIT first identified the assets. For violations of any of the REIT asset tests due to reasonable cause that are larger than this amount, a REIT may avoid disqualification as a REIT after the 30-day cure period, if such failure was due to reasonable cause and not due to willful neglect, by taking certain steps, including the disposition of sufficient assets within the six-month period described above to meet the applicable asset test, paying a tax equal to the greater of $50,000 or the highest corporate tax rate multiplied by the net income generated by the non-qualifying assets during the period of time that the assets were held as non-qualifying assets, and filing a schedule with the IRS that describes the non-qualifying assets.

Annual Distribution Requirements

To qualify for taxation as a REIT, the Internal Revenue Code requires that we make distributions (other than capital gain distributions) to our shareholders in an amount at least equal to (a) the sum of: (1) 90% of our “REIT taxable income” (computed without regard to the dividends paid deduction and our net capital gain), and (2) 90% of the net income, if any, from foreclosure property in excess of the special tax on income from foreclosure property, minus (b) the sum of certain items of non-cash income.

We must pay distributions in the taxable year to which they relate. Dividends paid in the subsequent year, however, will be treated as if paid in the prior year for purposes of the prior year’s distribution requirement if the dividends satisfy one of the following two sets of criteria:

•

We declare the dividends in October, November or December, the dividends are payable to shareholders of record on a specified date in such a month, and we actually pay the dividends during January of the subsequent year; or

•

We declare the dividends before we timely file our federal income tax return for such year, we pay the dividends in the 12-month period following the close of the prior year and not later than the first regular dividend payment after the declaration, and we elect on our federal income tax return for the prior year to have a specified amount of the subsequent dividend treated as if paid in the prior year.

Even if we satisfy the foregoing distribution requirements, we will be subject to tax thereon to the extent that we do not distribute all of our net capital gain or “REIT taxable income” as adjusted. Furthermore, if we fail to distribute at least the sum of 85% of our ordinary income for that year; 95% of our capital gain net income for that year; and any undistributed taxable income from prior periods, we would be subject to a 4% excise tax on the excess of the required distribution over the amounts actually distributed.

In addition, if during the 10-year recognition period, we dispose of any asset subject to the Built-in Gains Tax Rules described above, we must, pursuant to guidance issued by the IRS, distribute at least 90% of the built-in gain (after tax), if any, recognized on the disposition of the asset.

We may elect to retain rather than distribute all or a portion of our net capital gains and pay the tax on the gains. In that case, we may elect to have our shareholders include their proportionate share of the undistributed net capital gains in income as long-term capital gains and receive a credit for their share of the tax we paid. For purposes of the 4% excise tax described, any such retained amounts would be treated as having been distributed.

We intend to make timely distributions sufficient to satisfy the annual distribution requirements. In this regard, the partnership agreement of the Operating Partnership authorizes us, as general partner, to take such steps as may be necessary to cause the Operating Partnership to distribute to its partners an amount sufficient to permit us to meet these distribution requirements.

We expect that our REIT taxable income will be less than our cash flow due to the allowance of depreciation and other non-cash charges in computing REIT taxable income. Accordingly, we anticipate that we generally will have sufficient cash or liquid assets to enable us to satisfy the 90% distribution requirement. It is possible, however, that we, from time to time, may not have sufficient cash or other liquid assets to satisfy the 90% distribution requirement or to distribute such greater amount as may be necessary to avoid income and excise taxation. In this event, we may find it necessary to arrange for borrowings or, if possible, pay taxable stock dividends in order to satisfy the distribution requirement or avoid such income or excise taxation.

In the event that we are subject to an adjustment to our REIT taxable income (as defined in Section 860(d)(2) of the Internal Revenue Code) resulting from an adverse determination by either a final court decision, a closing agreement between us and the IRS under Section 7121 of the Internal Revenue Code, or an agreement as to tax liability between us and an IRS district director, or, an amendment or supplement to our federal income tax return for the applicable tax year, we may be able to rectify any resulting failure to satisfy the 90% annual distribution requirement by paying “deficiency dividends” to shareholders that relate to the adjusted year but that are paid in a subsequent year. To qualify as a deficiency dividend, we must make the distribution within 90 days of the adverse determination and we also must satisfy other procedural requirements. If we satisfy the statutory requirements of Section 860 of the Internal Revenue Code, a deduction is allowed for any deficiency dividend we subsequently paid to offset an increase in our REIT taxable income resulting from the adverse determination. We, however, must pay statutory interest on the amount of any deduction taken for deficiency dividends to compensate for the deferral of the tax liability.

Failure To Qualify

A violation of a REIT requirement other than the gross income tests or the asset tests will not cause us to lose our qualification as a REIT if the violation is due to reasonable cause and not due to willful neglect and we pay a penalty of $50,000 for each failure to satisfy the provision. If we fail to qualify for taxation as a REIT in any taxable year and the relief provisions do not apply, we will be subject to tax (including any applicable alternative minimum tax) on our taxable income at regular corporate rates. Distributions to shareholders in any year in which we fail to qualify as a REIT will not be deductible by us nor will they be required to be made. In that event, to the extent of our positive current and accumulated earnings and profits, distributions to shareholders will be dividends, generally taxable at long-term capital gains tax rates (as described below), subject to certain limitations of the Internal Revenue Code, and corporate distributees may be eligible for the dividends-received deduction. Unless we are entitled to relief under specific statutory provisions, we also will be disqualified from taxation as a REIT for the four taxable years following the year during which we lost our REIT qualification. We cannot state whether in all circumstances we would be entitled to such statutory relief. For example, if we fail to satisfy the gross income tests because non-qualifying income that we intentionally incur exceeds the limit on such income, the IRS could conclude that our failure to satisfy the tests was not due to reasonable cause.

Taxation of U.S. Shareholders

As used in this prospectus, the term “U.S. Shareholder” means a holder of our stock that, for federal income tax purposes:

•

is a citizen or resident of the United States;

•

is a corporation (including an entity treated as a corporation for federal income tax purposes) created or organized in or under the laws of the United States or of any political subdivision thereof;

•

is an estate, the income of which is subject to federal income taxation regardless of its source;

•

is any trust if a court within the United States is able to exercise primary supervision over the administration of the trust, and one or more United States persons have the authority to control all substantial decisions of the trust; or

•

is an eligible trust that elects to be taxed as a U.S. person under applicable Treasury Regulations.

For U.S. federal income tax purposes, income earned through an entity that is classified as a partnership for U.S. federal income tax purposes, regardless of where it was organized, is generally attributed to its partners. Accordingly, the U.S. federal income tax treatment of a partner in a partnership that holds our stock will generally depend on the status of the partner and the activities of the partnership. Prospective shareholders that are partnerships should consult their tax advisers concerning the U.S. federal income tax consequences to their partners of the acquisition, ownership and disposition of our stock.

For any taxable year for which we qualify for taxation as a REIT, taxable U.S. Shareholders will be taxed as discussed below.

Distributions Generally. Distributions to U.S. Shareholders, other than capital gain dividends discussed below, will constitute dividends up to the amount of our positive current and accumulated earnings and profits and, to that extent, will be taxable to the U.S. Shareholders. These distributions are not eligible for the dividends-received deduction for corporations. Certain “qualified dividend income” received by U.S. non-corporate shareholders in taxable years 2003 through 2012 is subject to tax at the same tax rates as long-term capital gain (generally, a maximum rate of 15% for such taxable years). Dividends received from REITs, however, generally are not eligible for these reduced rates and, therefore, will continue to be subject to tax at ordinary income rates (generally, a maximum rate of 35% for taxable years 2003-2012), subject to two narrow exceptions. Under the first exception, dividends received from a REIT may be treated as “qualified dividend income” eligible for the reduced tax rates to the extent that the REIT itself has received qualified dividend income from other corporations (such as taxable REIT subsidiaries). Under the second exception, dividends paid by a REIT in a taxable year may be treated as qualified dividend income in an amount equal to the sum of (i) the excess of the REIT’s “REIT taxable income” for the preceding taxable year over the corporate-level federal income tax payable by the REIT for such preceding taxable year and (ii) the excess of the REIT’s income that was subject to the Built-in Gains Tax in the preceding taxable year over the tax payable by the REIT on such income for such preceding taxable year. We do not anticipate that a material portion of our distributions will be treated as qualified dividend income.

To the extent that we make a distribution in excess of our positive current and accumulated earnings and profits, the distribution will be treated first as a tax-free return of capital, reducing the tax basis in the U.S. Shareholder’s stock, and then any distribution in excess of such basis will be taxable to the U.S. Shareholder as gain realized from the sale of its stock. Dividends we declared in October, November or December of any year payable to a U.S. Shareholder of record on a specified date in any such month will be treated as both paid by us and received by the shareholders on December 31 of that year, provided that we actually pay the dividends during January of the following calendar year.

Capital Gain Dividends. Distributions to U.S. Shareholders that we properly designate as capital gain dividends will be treated as long-term capital gains (to the extent they do not exceed our actual net capital gain) for the taxable year without regard to the period for which the U.S. Shareholder has held his or her stock. However, corporate shareholders may be required to treat up to 20% of certain capital gain dividends as ordinary income. Capital gain dividends are not eligible for the dividends-received deduction for corporations.

We may elect to retain and pay income tax on net long-term capital gain that we received during the tax year. In this instance, U.S. Shareholders will include in their income their proportionate share of the undistributed long-term capital gains as we designated. The U.S. Shareholders will also be deemed to have paid their proportionate share of the tax, which would be credited against such shareholders’ U.S. income tax liability (and refunded to the extent it exceeds such liability). In addition, the basis of the U.S. Shareholders’ shares will be increased by the excess of the amount of capital gain included in its income over the amount of tax it is deemed to have paid.

Any capital gain with respect to capital assets held for more than one year that is recognized or otherwise properly taken into account before January 1, 2013, generally will be taxed to a non-corporate taxpayer at a

maximum rate of 15%. In the case of capital gain attributable to the sale of real property held for more than one year, such gain will be taxed at a maximum rate of 25% to the extent of the amount of depreciation deductions previously claimed with respect to such property. With respect to distributions we designate as capital gain dividends (including any deemed distributions of retained capital gains), subject to certain limits, we may designate, and will notify our shareholders, whether the dividend is taxable to non-corporate shareholders at regular long-term capital gains rates (currently at a minimum rate of 15%) or at the 25% rate applicable to unrecaptured depreciation.

Passive Activity Loss and Investment Interest Limitations. Distributions from us and gain from the disposition of our stock will not be treated as passive activity income, and, therefore, U.S. Shareholders will not be able to apply any “passive losses” against such income. Dividends from us (to the extent they do not constitute a return of capital) generally will be treated as investment income for purposes of the investment interest limitation. Net capital gain from the disposition of our stock or capital gain dividends generally will be excluded from investment income unless the U.S. Shareholder elects to have the gain taxed at ordinary income rates. Shareholders are not allowed to include on their own federal income tax returns any tax losses that we incur.

Dispositions of Shares. In general, U.S. Shareholders will realize capital gain or loss on the disposition of our stock equal to the difference between the amount of cash and the fair market value of any property received on the disposition and that shareholder’s adjusted basis in the stock. This gain or loss will be a capital gain or loss if the U.S. Shareholder has held the shares as a capital asset. The applicable tax rate will depend on the shareholder’s holding period in the asset (generally, if the shareholder has held the asset for more than one year, it will produce long-term capital gain) and the shareholder’s tax bracket (the maximum rate for non-corporate taxpayers currently being 15% through 2012). The IRS has the authority to prescribe, but has not yet prescribed, regulations that would apply a capital gain tax rate of 25% (which is generally higher than the long-term capital gain tax rates for non-corporate shareholders) to a portion of capital gain realized by a non-corporate shareholder on the sale of our stock that would correspond to our “unrecaptured Section 1250 gain.” Shareholders should consult with their own tax advisors with respect to their capital gain tax liability. In general, any loss recognized by a U.S. Shareholder upon the sale or other disposition of stock that the shareholder has held for six months or less, after applying the holding period rules, will be treated as a long-term capital loss, to the extent of distributions received by the U.S. Shareholder from us that were required to be treated as long-term capital gains.

New Unearned Income Medicare Tax. Under the Health Care and Education Reconciliation Act of 2010, amending the Patient Protection and Affordable Care Act, high-income U.S. individuals, estates, and trusts will be subject to an additional 3.8% tax on net investment income in tax years beginning after December 31, 2012. For these purposes, net investment income includes dividends and gains from sales of stock. In the case of an individual, the tax will be 3.8% of the lesser of the individuals’ net investment income or the excess of the individuals’ modified adjusted gross income over $250,000 in the case of a married individual filing a joint return or a surviving spouse, $125,000 in the case of a married individual filing a separate return, or $200,000 in the case of a single individual. U.S. Shareholders that are individuals, estates or trusts should consult their tax advisors regarding the effect, if any, of this legislation on their ownership and disposition of our common stock.

Extension of Reduced Tax Rate Provisions. The Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 extended the sunset provisions described herein. For taxable years beginning after December 31, 2012, the 15% capital gains tax rate for non-corporate taxpayers is currently scheduled to increase to 20%, and the rate applicable to qualified dividend income will increase to the tax rate then applicable to ordinary income, the maximum rate for which is scheduled to increase to 39.6%.

Treatment of Tax-Exempt Shareholders. Distributions from us to a tax-exempt employee pension trust or other domestic tax-exempt shareholder generally will not constitute “unrelated business taxable income,” which we refer to as “UBTI,” unless the shareholder has borrowed to acquire or carry its stock or has used the shares in a trade or business.

However, for tax-exempt shareholders that are social clubs, voluntary employee benefit associations, supplemental unemployment benefit trusts and qualified group legal services plans exempt from federal income taxation under Sections 501(c)(7), (c)(9), (c)(17) and (c)(20) of the Internal Revenue Code, respectively, income from an investment in us will constitute UBTI unless the organization properly sets aside or reserves such amounts for purposes specified in the Internal Revenue Code. These tax-exempt shareholders should consult their own tax advisors concerning these “set aside” and reserve requirements.

Qualified trusts that hold more than 10% (by value) of the shares of a “pension-held REIT” may be required to treat a certain percentage of such a REIT’s distributions as UBTI. A REIT is a “pension-held REIT” only if the REIT would not qualify as such for federal income tax purposes but for the application of a “look-through” exception to the five or fewer requirement applicable to shares held by qualified trusts and the REIT is “predominantly held” by qualified trusts. A REIT is predominantly held if either at least one qualified trust holds more than 25% by value of the REIT interests or qualified trusts, each owning more than 10% by value of the REIT interests, holds in the aggregate more than 50% of the REIT interests. The percentage of any REIT dividend treated as UBTI is equal to the ratio of (a) the UBTI earned by the REIT (treating the REIT as if it were a qualified trust and therefore subject to tax on UBTI) to (b) the total gross income (less certain associated expenses) of the REIT. In the event that this ratio is less than 5% for any year, then the qualified trust will not be treated as having received UBTI as a result of the REIT dividend. For these purposes, a qualified trust is any trust described in Section 401(a) of the Internal Revenue Code and exempt from tax under Section 501(a) of the Internal Revenue Code.

Special Tax Considerations For Non-U.S. Shareholders

In general, non-U.S. Shareholders will be subject to regular federal income tax with respect to their investment in us if the income from the investment is “effectively connected” with the non-U.S. Shareholder’s conduct of a trade or business in the United States. A corporate non-U.S. Shareholder that receives income that is (or is treated as) effectively connected with a U.S. trade or business also may be subject to the branch profits tax under Section 884 of the Internal Revenue Code, which is imposed in addition to regular federal income tax at the rate of 30%, subject to reduction under a tax treaty, if applicable. Effectively connected income that meets various certification requirements will generally be exempt from withholding. The following discussion will apply to non-U.S. Shareholders whose income from their investments in us is not so effectively connected (except to the extent that the FIRPTA rules discussed below treat such income as effectively connected income).

Distributions by us that are not attributable to gain from the sale or exchange by us of a “United States real property interest” and that we do not designate as a capital gain distribution will be treated as an ordinary income dividend to the extent that we pay the distribution out of our current or accumulated earnings and profits. Generally, any ordinary income dividend will be subject to a federal income tax, required to be withheld by us, equal to 30% of the gross amount of the dividend, unless an applicable tax treaty reduces this tax. Such a distribution in excess of our earnings and profits will be treated first as a return of capital that will reduce a non-U.S. Shareholder’s basis in its stock (but not below zero) and then as gain from the disposition of such stock, the tax treatment of which is described under the rules discussed below with respect to dispositions of stock.

Distributions by us with respect to our common stock that are attributable to gain from the sale or exchange of a United States real property interest will be treated as ordinary dividends (taxed as described above) to a non-U.S. Shareholder as long as our common stock is “regularly traded” on an established securities market if the non-U.S. Shareholder did not own more than 5% of such class of stock at any time during the one-year period preceding the distribution. Capital gain dividends distributed to a non-U.S. Shareholder that held more than 5% of our common stock in the year preceding the distribution will be taxed under the Foreign Investment in Real Property Tax Act of 1980, or “FIRPTA.” Such distributions are taxed to a non-U.S. Shareholder as if the distributions were gains “effectively connected” with a United States trade or business. Accordingly, a non-U.S. Shareholder will be required to report such gains on U.S. federal income tax returns and will be taxed at the normal capital gain rates applicable to a U.S. Shareholder (subject to any applicable alternative minimum tax and

a special alternative minimum tax in the case of nonresident alien individuals). Such distributions also may be subject to a 30% branch profits tax when made to a foreign corporation that is not entitled to an exemption or reduced branch profits tax rate under a tax treaty.

Although the law is not clear on this matter, it appears that amounts designated by us as undistributed capital gains in respect of our stock generally should be treated with respect to non-U.S. Shareholders in the same manner as actual distributions by us of capital gain dividends.

Although tax treaties may reduce our withholding obligations, we generally will be required to withhold from distributions to non-U.S. Shareholders, and remit to the IRS, 30% of ordinary dividends paid out of earnings and profits. Special withholding rules apply to capital gain dividends that are not recharacterized as ordinary dividends. In addition, we may be required to withhold 10% of distributions in excess of our current and accumulated earnings and profits. If the amount of tax withheld by us with respect to a distribution to a non-U.S. Shareholder exceeds the shareholder’s United States tax liability, the non-U.S. Shareholder may file for a refund of such excess from the IRS.

We expect to withhold federal income tax at the rate of 30% on all distributions (including distributions that later may be determined to have been in excess of current and accumulated earnings and profits) made to a non-U.S. Shareholder unless:

•

a lower treaty rate applies and the non-U.S. Shareholder files with us an IRS Form W-8BEN evidencing eligibility for that reduced treaty rate;

•

the non-U.S. Shareholder files with us an IRS Form W-8ECI claiming that the distribution is income effectively connected with the non-U.S. Shareholder’s trade or business so that no withholding tax is required; or

•

the distributions are treated for FIRPTA withholding tax purposes as attributable to a sale of a U.S. real property interest, in which case tax will be withheld at a 35% rate.

Unless our stock constitutes a “United States real property interest” within the meaning of FIRPTA, a sale of our stock by a non-U.S. Shareholder generally will not be subject to federal income taxation. Our stock will not constitute a United States real property interest if we are a “domestically controlled qualified investment entity.” A domestically controlled qualified investment entity is a REIT in which at all times during a specified testing period less than 50% in value of its shares is held directly or indirectly by non-U.S. Shareholders. We currently anticipate that we will be a domestically controlled qualified investment entity and, therefore, that the sale of our stock will not be subject to taxation under FIRPTA. However, because our stock will be publicly traded, we cannot assure you that we will be a domestically controlled qualified investment entity. If we were not a domestically controlled qualified investment entity, a non-U.S. Shareholder’s sale of our stock would be subject to tax under FIRPTA as a sale of a United States real property interest unless the stock were “regularly traded” on an established securities market (such as the New York Stock Exchange) on which the stock will be listed and the selling shareholder owned no more than 5% of the common stock throughout the applicable testing period. If the gain on the sale of stock were subject to taxation under FIRPTA, the non-U.S. Shareholder would be subject to the same treatment as a U.S. Shareholder with respect to the gain (subject to applicable alternative minimum tax and a special alternative minimum tax in the case of nonresident alien individuals). However, even if our stock is not a United States real property interest, a nonresident alien individual’s gains from the sale of stock will be taxable if the nonresident alien individual is present in the United States for 183 days or more during the taxable year and certain other conditions apply, in which case the nonresident alien individual will be subject to a 30% tax on his or her U.S.-source capital gains.

Recently enacted amendments to the Code generally impose a U.S. federal withholding tax of 30% on certain types of payments, including dividends on and gross proceeds from a sale or exchange of shares of our common stock to (i) a foreign financial institution unless the foreign financial institution enters into an agreement

with the U.S. government to undertake to obtain and provide to the U.S. tax authorities substantial information regarding certain direct and indirect U.S. accountholders and to collect the withholding tax on payments to certain accountholders (generally where the actions of the accountholders prevent compliance with reporting and other requirements), and the foreign financial institution meets certain other specified requirements or (ii) a non-financial foreign entity unless the foreign entity certifies that it does not have any direct or indirect substantial U.S. owners or provides the name, address and taxpayer identification number of each direct and indirect substantial U.S. owner, and the foreign entity meets certain other specified requirements. While the Code would apply such withholding obligations to payments made after December 31, 2012, recent proposed regulations would delay withholding with respect to dividends to payments made after December 31, 2012 and with respect to payments of gross proceeds from dispositions of stock occurring after December 31, 2012. Under certain circumstances, a non-U.S. Shareholder might be eligible for refunds or credits of any withholding taxes. Non-U.S. Shareholders are encouraged to consult their tax advisors regarding the possible implications of these new provisions of the Code on their investment in our common stock.

A purchaser of our stock from a non-U.S. Shareholder will not be required to withhold under FIRPTA on the purchase price if the purchased stock is “regularly traded” on an established securities market. Otherwise, the purchaser of our stock from a non-U.S. Shareholder may be required to withhold 10% of the purchase price and remit this amount to the IRS. Our common stock currently is traded on the New York Stock Exchange. We believe that we qualify under the regularly traded exception to withholding, but we cannot provide any assurance to that effect.

Upon the death of a nonresident alien individual, that individual’s ownership of our stock will be treated as part of his or her U.S. estate for purposes of the U.S. estate tax, except as may be otherwise provided in an applicable estate tax treaty.

Information Reporting Requirements and Backup Withholding Tax

U.S. Shareholders. In general, information reporting requirements will apply to payments of distributions on our stock and payments of the proceeds of the sale of our stock, unless an exception applies. Further, the payer will be required to withhold backup withholding tax if:

•

the payee fails to furnish a taxpayer identification number to the payer or to establish an exemption from backup withholding;

•

the IRS notifies the payer that the taxpayer identification number furnished by the payee is incorrect;

•

a notified payee has been under-reporting with respect to interest, dividends or original issue discount described in Section 3406(c) of the Internal Revenue Code; or

•

the payee has failed to certify under the penalty of perjury that the payee is not subject to backup withholding under the Internal Revenue Code.

Some shareholders, including corporations, will be exempt from backup withholding. Any amounts withheld under the backup withholding rules from a payment to a shareholder will be allowed as a credit against the shareholder’s federal income tax and may entitle the shareholder to a refund, provided that the shareholder furnishes the required information to the IRS.

Non-U.S. Shareholders. Generally, information reporting will apply to payments of distributions on Duke Realty’s stock, and backup withholding may apply, unless the payee certifies that it is not a U.S. person or otherwise establishes an exemption.

The payment of the proceeds from the disposition of our stock to or through the U.S. office of a U.S. or foreign broker will be subject to information reporting and, possibly, backup withholding unless the non-U.S. Shareholder certifies as to its non-U.S. status or otherwise establishes an exemption, provided that the broker

does not have actual knowledge that the shareholder is a U.S. person or that the conditions of any other exemption are not, in fact, satisfied. The proceeds of the disposition by a non-U.S. Shareholder of our stock to or through a foreign office of a broker generally will not be subject to information reporting or backup withholding. However, if the broker is a U.S. person, a controlled foreign corporation for U.S. tax purposes or a foreign person 50% or more whose gross income from all sources for specified periods is from activities that are effectively connected with a U.S. trade or business, information reporting generally will apply unless the broker has documentary evidence as to the non-U.S. Shareholder’s foreign status and has no actual knowledge to the contrary.

Applicable Treasury regulations provide presumptions regarding the status of shareholders when payments to the shareholders cannot be reliably associated with appropriate documentation provided to the payer. Under these Treasury regulations, some shareholders are required to have provided new certifications with respect to payments made after December 31, 2000. Because the application of these Treasury regulations varies depending on the shareholder’s particular circumstances, you should consult your tax advisor regarding the information reporting requirements applicable to you.

Tax Basis and Other Information Reporting. Brokers are subject to information reporting requirements relating to certain transactions involving shares of our capital stock acquired on or after January 1, 2011 by a shareholder other than an exempt recipient (“covered stock”). Specifically, upon the transfer or redemption of shares of covered stock, the broker must report certain information to the shareholder and the IRS, including the adjusted tax basis of the shares and whether any gain or loss recognized on the transfer or redemption is long-term or short-term. Shares of covered stock will be transferred or redeemed on a “first in/first out” basis unless the shareholder identifies specific lots to be transferred or redeemed in a timely manner.

If we take an organizational action such as a stock split, merger, or acquisition that affects the tax basis of shares of covered stock or even make distributions that exceed our current or accumulated earnings and profits, we will report to each shareholder and the IRS (or post on our primary public Web site) a description of the action and the quantitative effect of that action on the tax basis of the applicable shares. Although corporations generally qualify as exempt recipients, an S corporation will not qualify as an exempt recipient with respect to shares of our common stock that the S corporation acquires on or after January 1, 2012. Thus, the transfer or redemption of shares of our capital stock acquired by an S corporation on or after January 1, 2012 will be subject to the reporting requirements discussed above.

Brokers may be subject to transfer statement reporting on certain transactions not otherwise subject to the reporting requirements discussed above (excluding transactions involving shares acquired before January 1, 2011). Transfer statements, however, are issued only between “brokers” and are not issued to shareholders or the IRS.

Shareholders are encouraged to consult their tax advisors regarding the application of the information reporting rules discussed above to their investment in our common stock.

Tax Aspects of the Operating Partnership

General. The Operating Partnership holds substantially all of our investments. In general, partnerships are “pass-through” entities that are not subject to federal income tax. Rather, partners are allocated their proportionate shares of the items of income, gain, loss, deduction and credit of a partnership, and are potentially subject to tax thereon, without regard to whether the partners receive a distribution from the partnership. We include in our income our proportionate share of these Operating Partnership items for purposes of the various REIT income tests and in the computation of our REIT taxable income. Moreover, for purposes of the REIT asset tests, we include our proportionate share of assets held by the Operating Partnership.

Tax Allocations with Respect to the Properties. Pursuant to Section 704(c) of the Internal Revenue Code, income, gain, loss and deduction attributable to appreciated or depreciated property that is contributed to a

partnership in exchange for an interest in the partnership, must be allocated in a manner such that the contributing partner is charged with the unrealized gain, or benefits from the unrealized loss, associated with the property at the time of the contribution. The amount of the unrealized gain or unrealized loss is generally equal to the difference between the fair market value of contributed property at the time of contribution and the adjusted tax basis of the property at the time of contribution, which we refer to as a “book-tax difference.” These allocations are solely for federal income tax purposes and do not affect the book capital accounts or other economic or legal arrangements among the partners. The Operating Partnership was formed by way of contributions of appreciated property. Consequently, the partnership agreement of the Operating Partnership requires allocations to be made in a manner consistent with Section 704(c) of the Internal Revenue Code.

In general, the partners who have contributed interests in appreciated properties to the Operating Partnership will be allocated lower amounts of depreciation deductions for tax purposes than such deductions would be if determined on a pro rata basis. In addition, in the event of the disposition of any of the contributed assets that have a book-tax difference, all taxable income attributable to the book-tax difference generally will be allocated to the contributing partners, and we generally will be allocated only our share of capital gains attributable to appreciation, if any, occurring after the closing of the acquisition of the properties. This will tend to eliminate the book-tax difference over the life of the Operating Partnership. However, the special allocation rules of Section 704(c) of the Internal Revenue Code do not always entirely eliminate the book-tax difference on an annual basis or with respect to a specific taxable transaction such as a sale. Thus, the carryover basis of the contributed assets in the hands of the Operating Partnership will cause us to be allocated lower depreciation and other deductions and possibly amounts of taxable income in the event of a sale of the contributed assets in excess of the economic or book income allocated to it as a result of the sale. This may cause us to recognize taxable income in excess of cash proceeds, which might adversely affect our ability to comply with the REIT distribution requirements.

Treasury Regulations under Section 704(c) of the Internal Revenue Code provide partnerships with a choice of several methods of accounting for book-tax differences, including the “traditional method” that may leave some of the book-tax differences unaccounted for, or the election of certain methods which would permit any distortions caused by a book-tax difference to be entirely rectified on an annual basis or with respect to a specific taxable transaction such as a sale. For most property contributions, we, along with the Operating Partnership, have determined to use the “traditional method” for accounting for book-tax differences with respect to the properties contributed to the Operating Partnership. As a result of this determination, distributions to shareholders will be comprised of a greater portion of taxable income and less return of capital than if another method for accounting for book-tax differences had been selected. We, along with the Operating Partnership, have not determined which of the alternative methods of accounting for book-tax differences will be elected with respect to properties contributed to the Operating Partnership in the future.

With respect to any property purchased by the Operating Partnership, this property initially will have a tax basis equal to its fair market value and Section 704(c) of the Internal Revenue Code will not apply.

Basis in Operating Partnership Interest. Our adjusted tax basis in our interest in the Operating Partnership generally:

•

will equal the amount of cash and the basis of any other property that we contributed to the Operating Partnership;

•

will increase by our allocable share of the Operating Partnership’s income and our allocable share of debt of the Operating Partnership; and

•

will decrease, but not below zero, by our allocable share of losses suffered by the Operating Partnership, the amount of cash distributed to us, and constructive distributions resulting from a reduction in our share of debt of the Operating Partnership.

If the allocation of our distributive share of the Operating Partnership’s loss exceeds the adjusted tax basis of our partnership interest in the Operating Partnership, the recognition of the excess loss will be deferred until such time and to the extent that we have an adjusted tax basis in our interest in the Operating Partnership. To the extent that the Operating Partnership’s distributions, or any decrease in our share of the debt of the Operating Partnership (such decreases being considered a cash distribution to the partners) exceed our adjusted tax basis, the excess distributions (including such constructive distributions) constitute taxable income to us. This taxable income normally will be characterized as long-term capital gain if we have held our interest in the Operating Partnership for longer than one year, subject to reduced tax rates described above for non-corporate U.S. Shareholders, to the extent designated by us as a capital gain dividend. Under current law, capital gains and ordinary income of corporations generally are taxed at the same marginal rates.

Sale of the Properties. Our share of gain realized by the Operating Partnership on the sale of any property held by the Operating Partnership as inventory or other property held primarily for sale to customers in the ordinary course of the Operating Partnership’s trade or business will be treated as income from a prohibited transaction that is subject to a 100% penalty tax. Prohibited transaction income also may have an adverse effect upon our ability to satisfy the income tests for qualification as a REIT. Under existing law, whether the Operating Partnership holds its property as inventory or primarily for sale to customers in the ordinary course of its trade or business is a question of fact that depends on all the facts and circumstances with respect to the particular transaction. The Operating Partnership intends to hold the properties for investment with a view to long-term appreciation, to engage in the business of acquiring, developing, owning and operating the properties and to make such occasional sales of the properties, including peripheral land, as are consistent with the Operating Partnership’s investment objectives.

State and Local Tax

We and our shareholders may be subject to state and local tax in various states and localities, including those in which we or they transact business, own property or reside. The tax treatment of us and the shareholders in such jurisdictions may differ from the federal income tax treatment described above. Consequently, prospective shareholders should consult their own tax advisors regarding the effect of state and local tax laws on an investment in our stock.

SELLING SECURITYHOLDERS

Selling securityholders are persons or entities that, directly or indirectly, have acquired or will from time to time acquire from us or the Operating Partnership common stock, preferred stock, depositary shares, warrants, stock purchase contracts, debt securities or units, as applicable, in various private transactions. Such selling securityholders may be parties to registration rights agreements with us, or we otherwise may have agreed or will agree to register their securities for resale. The initial purchasers of our securities, as well as their transferees, pledgees, donees or successors, all of whom we refer to as “selling securityholders,” may from time to time offer and sell the securities pursuant to this prospectus and any applicable prospectus supplement.

The selling securityholders may offer for sale all or some portion of the securities that they hold. To the extent that any of the selling securityholders are broker or dealers, they are deemed to be, under interpretations of the SEC, “underwriters” within the meaning of the Securities Act.

The applicable prospectus supplement will set forth the name of each of the selling securityholders and the number and classes of our securities beneficially owned by such selling securityholders that are covered by such prospectus supplement. The applicable prospectus supplement will also disclose whether any of the selling securityholders has held any position or office with, has been employed by or otherwise has had a material relationship with us during the three years prior to the date of the prospectus supplement.

PLAN OF DISTRIBUTION

Duke Realty, the Operating Partnership and the selling securityholders may sell the securities offered under this prospectus:

•

through underwriting syndicates represented by one or more managing underwriters;

•

to or through underwriters or dealers;

•

to or through agents;

•

directly to one or more purchasers; or

•

through a combination of any such method of sale.

Such sales may be made from time to time in one or more transactions at:

•

a fixed price;

•

market prices prevailing at the time of sale;

•

prices related to prevailing market prices; or

•

negotiated prices.

Any of the prices may represent a discount from the prevailing market prices.

Duke Realty, the Operating Partnership and the selling securityholders will describe the name or names of any underwriters, dealers or agents and the purchase price of the securities in a prospectus supplement relating to the securities.

Any underwritten offering may be on a best efforts or a firm commitment basis. If underwriters are used in the sale, the securities acquired by the underwriters will be for their own account. The underwriters may resell such securities from time to time in one or more transactions, including, without limitation, negotiated transactions, at fixed public offering prices or at varying prices determined by the underwriters, at the time of sale. Securities may be offered to the public either through underwriting syndicates represented by managing underwriters or directly by one or more underwriters. The obligations, if any, of the underwriter to purchase any securities will be subject to certain conditions. The underwriters will be obligated to purchase all of the securities if any are purchased.

In connection with the sale of the securities, underwriters may receive compensation from Duke Realty, the Operating Partnership, selling securityholders or from purchasers of the securities, for whom they may act as agents, in the form of discounts, concessions or commissions. Underwriters may sell the securities to or through dealers, and these dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. Any public offering price and any discounts or concessions allowed, reallowed, or paid to dealers may be changed from time to time. Underwriters, dealers and agents that participate in the distribution of the securities may be deemed to be underwriters, and any discounts or commissions they receive from Duke Realty or the Operating Partnership, and any profit on the resale of the securities they realize, may be deemed to be underwriting discounts and commissions, under the Securities Act. The prospectus supplement will identify any underwriter or agent and will describe any compensation they receive from Duke Realty or the Operating Partnership.

We may also make direct sales through subscription rights distributed to our shareholders on a pro rata basis, which may or may not be transferable. In any distribution of subscription rights to shareholders, if all of the securities are not subscribed for, we may then sell the unsubscribed securities directly to third parties or may engage the services of one or more underwriters, dealers, or agents, including standby underwriters, to sell the unsubscribed securities to third parties.

Pursuant to this registration, we intend to provide applicable selling securityholders with freely tradable securities, although the registration of these securities does not necessarily mean that securities will be offered or sold by such selling securityholders under this prospectus.

We will not receive any proceeds from the sale of the securities by the selling securityholders, but in certain cases we may pay fees and expenses relating to the registration or an offering of such securities, such as registration and filing fees, fees and expenses for complying with federal and state securities laws and FINRA rules and regulations, and fees and expenses incurred in connection with a listing, if any, of any of the securities on any securities exchange or association.

The selling securityholders and any dealers or agents that participate in the distribution of such securities may be deemed to be “underwriters” within the meaning of the Securities Act and any profit on the resale of the securities by them and any commissions received by any of these dealers or agents might be deemed to be underwriting commissions under the Securities Act.

To the extent required, the securities to be sold, the names of the selling securityholders, the respective purchase prices and public offering prices, the names of any agent, dealer or underwriter, and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement of which this prospectus is a part.

If we reach an agreement with an underwriter on a placement, including the number of shares of common stock to be offered in the placement and any minimum price below which sales may not be made, such underwriter would agree to use its commercially reasonable efforts, consistent with its normal trading and sales practices, to try to sell such shares on such terms. Underwriters could make sales in privately negotiated transactions and/or any other method permitted by law, including sales deemed to be an “at-the-market” offering as defined in Rule 415 promulgated under the Securities Act, sales made directly on the New York Stock Exchange, the existing trading market for Duke Realty’s common stock, or sales made to or through a market maker other than on an exchange. The name of any such underwriter or agent involved in the offer and sale of Duke Realty’s common stock, the amounts underwritten, and the nature of its obligations to take Duke Realty’s common stock will be described in the applicable prospectus supplement.

Unless otherwise specified in the prospectus supplement, each series of the securities will be a new issue with no established trading market, other than Duke Realty’s common stock, which is currently listed on the New York Stock Exchange. We currently intend to list any shares of common stock sold pursuant to this prospectus on the New York Stock Exchange. We may elect to list any series of debt securities, preferred stock or depositary shares on an exchange, but are not obligated to do so. It is possible that one or more underwriters may make a market in a series of the securities, but underwriters will not be obligated to do so and may discontinue any market making at any time without notice. Therefore, we can give no assurance about the liquidity of the trading market for any of the securities.

Under agreements we may enter into, we may indemnify underwriters, dealers and agents who participate in the distribution of the securities against certain liabilities, including liabilities under the Securities Act, or contribute with respect to payments that the underwriters, dealers or agents may be required to make.

From time to time, we may engage in transactions with these underwriters, dealers and agents in the ordinary course of business.

If indicated in the prospectus supplement, we may authorize underwriters or other persons acting as our agents to solicit offers by institutions to purchase securities from us pursuant to contracts providing for payment and delivery on a future date. Institutions with which we may make these delayed delivery contracts include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and others. The obligations of any purchaser under any such delayed delivery contract will be subject to the condition that the purchase of the securities shall not at the time of delivery be prohibited under the laws of the jurisdiction to which the purchaser is subject. The underwriters and other agents will not have any responsibility with regard to the validity or performance of these delayed delivery contracts.
