STATEMENT REGARDING FORWARD-LOOKING INFORMATION

This prospectus supplement, the accompanying prospectus and the documents incorporated by reference in this prospectus supplement and the accompanying prospectus, contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Such forward-looking statements include, without limitation, statements concerning property acquisitions and dispositions, development activity and capital expenditures, capital raising activities, rent growth, occupancy, and rental expense growth. Words such as “expects,” “anticipates,” “intends,” “plans,” “likely,” “will,” “believes,” “seeks,” “estimates,” and variations of such words and similar expressions are intended to identify such forward-looking statements. Such statements involve known and unknown risks, uncertainties and other factors which may cause our actual results, performance or achievements to be materially different from the results of operations or plans expressed or implied by such forward-looking statements. Such factors include, among other things, unfavorable changes in the apartment market, changing economic conditions, the impact of inflation/deflation on rental rates and property operating expenses, expectations concerning availability of capital and the stabilization of the capital markets, the impact of competition and competitive pricing, acquisitions, developments and redevelopments not achieving anticipated results, delays in completing developments, redevelopments and lease-ups on schedule, expectations on job growth, home affordability an demand/supply ratio for multifamily housing, expectations concerning development and redevelopment activities, and expectations on occupancy levels.

The following factors, among others, could cause our future results to differ materially from those expressed in the forward-looking statements:

general economic factors;

unfavorable changes in apartment market and economic conditions that could adversely affect occupancy levels and rental rates;

the failure of acquisitions to achieve anticipated results;

possible difficulty in selling apartment communities;

competitive factors that may limit our ability to lease apartment homes or increase or maintain rents;

insufficient cash flow that could affect our debt financing and create refinancing risk;

failure to generate sufficient revenue, which could impair our debt service payments and reduce distributions to stockholders;

development and construction risks that may impact our profitability;

potential damage from natural disasters, including hurricanes and other weather-related events, which could result in substantial costs to us;

risks from extraordinary losses for which we may not have insurance or adequate reserves;

uninsured losses due to insurance deductibles, self-insurance retention, uninsured claims or casualties, or losses in excess of applicable coverage;

delays in completing developments and lease-ups on schedule;

our failure to succeed in new markets;

iii

changing interest rates, which could increase interest costs and affect the market price of our securities;

potential liability for environmental contamination, which could result in substantial costs to us;

the imposition of federal taxes if we fail to qualify as a REIT under the Internal Revenue Code in any taxable year;

our internal control over financial reporting may not be considered effective which could result in a loss of investor confidence in our financial reports, and in turn have an adverse effect on our stock price; and

changes in real estate laws, tax laws and other laws affecting our business.

Please also refer to the section entitled “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011 and our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2012 for further information on these and other risks affecting us.

Although we believe that the assumptions underlying the forward-looking statements contained or incorporated by reference herein are reasonable, any of the assumptions could be inaccurate, and therefore such statements included or incorporated by reference herein may not prove to be accurate. In light of the significant uncertainties inherent in the forward-looking statements included or incorporated by reference herein, the inclusion or incorporation by reference of such information should not be regarded as a representation by us or any other person that the results or conditions described in such statements or our objectives and plans will be achieved.

Forward-looking statements and such risks, uncertainties and other factors speak only as of the date they are made, and we expressly disclaim any obligation or undertaking to update or revise any forward-looking statement contained or incorporated by reference herein, to reflect any change in our expectations with regard thereto, or any other change in events, conditions or circumstances on which any such statement is based, except to the extent otherwise required by law.

PROSPECTUS SUPPLEMENT SUMMARY

This summary highlights information more fully described elsewhere in this prospectus supplement and the accompanying prospectus. Before investing in our common stock, you should read carefully this entire prospectus supplement and the accompanying prospectus including the risks set forth under the caption “Risk Factors” beginning on page S-4 of this prospectus supplement, and the risks set forth under the caption “Risk Factors” included in our most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, which are incorporated by reference herein and in the accompanying prospectus, as the same may be updated from time to time by filings under the Exchange Act that we incorporate by reference herein and in the accompanying prospectus.

Our Company

We are a self-administered real estate investment trust, or REIT, that owns, operates, acquires, renovates, develops, redevelops and manages multifamily apartment communities generally located in high barrier-to-entry markets located throughout the United States. These high barrier-to-entry markets are characterized by limited land for new construction, difficult and lengthy entitlement processes, expensive single-family home prices and significant employment growth potential. As of March 31, 2012, our consolidated apartment portfolio included 157 communities located in 22 markets, with a total of 45,969 completed apartment homes which are held through the Operating Partnership and our subsidiaries. In addition, we have an ownership interest in 44 communities including 11,110 completed apartment homes through unconsolidated joint ventures. At March 31, 2012, the Company is developing five wholly-owned communities with 1,748 apartment homes, none of which have been completed.

We have elected to be taxed as a REIT under the applicable provisions of the Internal Revenue Code. To continue to qualify as a REIT under the Internal Revenue Code, we must continue to meet certain tests which, among other things, generally require that our assets consist primarily of real estate assets, our income be derived primarily from real estate assets, and that we distribute at least 90% of our REIT taxable income (other than our net capital gain) to our stockholders. As a qualified REIT, we generally will not be subject to U.S. federal income taxes on our REIT taxable income to the extent we distribute such income to our stockholders.

Additional information regarding UDR and the Operating Partnership is set forth in documents on file with the SEC and incorporated by reference in this prospectus supplement and the accompanying prospectus, as described in the sections entitled “Where You Can Find More Information” and “Incorporation of Certain Documents by Reference.”

Recent Developments

In March 2012, we entered into an agreement to sell 15 unencumbered communities containing 4,931 homes for $477 million in gross proceeds. The anticipated dispositions are located in Phoenix, AZ, Jacksonville, FL, Dallas, TX and Richmond, VA, and will mark our exit from the Phoenix and Jacksonville markets. The sale is expected to close during the second quarter of 2012, subject to customary closing conditions.

On April 27, 2012, we announced that we will redeem all issued and outstanding shares of our 6.75% Series G Cumulative Redeemable Preferred Stock on May 31, 2012. We will redeem the Series G Preferred Stock at a redemption price of $25 per share in cash, plus accrued and unpaid dividends to the redemption date. There are currently 3,264,362 shares of Series G Preferred Stock issued and outstanding. The total cash cost of

S-1

the redemption will be $81.6 million plus accrued and unpaid dividends up to the redemption date. Dividends will cease to accrue on all shares of Series G Preferred Stock on the redemption date.

On April 4, 2012, we entered into a new equity distribution agreement with respect to our “At the Market” equity distribution program, under which we may offer and sell up to 20 million shares of our common stock, from time to time, to or through our sales agents. As of May 21, 2012, we had sold 71,000 shares of common stock under our new equity distribution agreement.

You should read carefully the risks set forth under the caption “Risk Factors” beginning on page S-4 of this prospectus supplement and the risks set forth under the caption “Risk Factors” included in our most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, for certain considerations relevant to an investment in our common stock.

RISK FACTORS

Investing in our common stock involves risks. Before investing in our common stock, you should carefully consider, among other matters, the risks set forth under the caption “Risk Factors” included in our most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, which are incorporated by reference into this prospectus supplement and the accompanying prospectus, as the same may be updated from time to time by filings under the Exchange Act that we incorporate by reference herein and in the accompanying prospectus.

The market value of our common stock could be substantially affected by various factors.

Market volatility may adversely affect the market price of our common stock. As with other publically traded securities, the share price of our common stock depends on many factors, which may change from time to time, including:

the market for similar securities issued by REITs;

changes in estimates by analysts;

our ability to meet analysts’ estimates;

prevailing interest rates;

general economic and financial market conditions; and

our financial condition, performance and prospects.

Our issuance of additional capital stock or debt securities, whether or not convertible, may reduce the market price for shares of our common stock and dilute the ownership interests of existing stockholders.

We cannot predict the effect, if any, that future sales of our capital stock or debt securities, including sales pursuant to the sales agreement, or the availability of our securities for future sale, will have on the market price of shares of our common stock. Sales of substantial amounts of our common stock or preferred shares, or debt securities convertible into or exercisable or exchangeable for common stock in the public market, or the perception that such sales might occur, could negatively impact the market price of our common stock and the terms upon which we may obtain additional equity financing in the future. The issuance of any additional shares of our common stock or securities convertible into or exchangeable for common stock or that represent the right to receive common stock, or the exercise of such securities, could be substantially dilutive to holders of our common stock, including purchasers of common stock in this offering.

In addition, we may issue additional capital stock in the future to raise capital or as a result of the following:

the issuance and exercise of options to purchase our common stock;

the issuance of shares pursuant to our dividend reinvestment plan; and

the issuance of debt securities exchangeable for our common stock.

Legislative or regulatory action could adversely affect purchasers of our common stock.

In recent years, numerous legislative, judicial and administrative changes have been made in the provisions of the federal income tax laws applicable to investments similar to an investment in our common

S-4

stock. Changes are likely to continue to occur in the future, and we cannot assure you that any of these changes will not adversely affect our stockholders’ stock. Any of these changes could have an adverse effect on an investment in our common stock or on market value or resale potential of our common stock. Stockholders are urged to consult with their own tax advisor with respect to the impact that recent legislation may have on their investment and the status of legislative, regulatory or administrative developments and proposals and their potential effect on their investment in our stock.

S-5

USE OF PROCEEDS

We estimate that the net proceeds to us from this offering will be approximately $ million, or approximately $ million if the underwriters exercise their option to purchase additional shares in full, in each case after deducting underwriting discounts and estimated offering expenses.

We intend to use the net proceeds from this offering to repay approximately $364 million of our 3.3% secured debt due 2012-2014, to redeem all of our 6.75% Series G Preferred Stock for a total cash cost of $81.6 million plus accrued and unpaid dividends up to the redemption date, to repay approximately $28 million of indebtedness currently outstanding under our unsecured credit facility, which based on our current credit ratings carries an interest rate equal to LIBOR plus a spread of 122.5 basis points and has an initial term that expires on October 23, 2015 and the balance for working capital and general corporate purposes. As of May 25, 2012, the balance under our unsecured credit facility was approximately $322 million.

Banking affiliates of Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC are lenders under our unsecured credit facility. Certain of these affiliates may receive proceeds from the repayment of our secured debt from the net proceeds of this offering. See “Underwriting (Conflict of Interest)—Conflict of Interest.”

As of May 25, 2012, there were 243,244,277 shares of our common stock issued and outstanding, which does not include 9,415,819 shares of common stock issuable upon the exercise of outstanding operating partnership units; 3,035,548 shares of common stock issuable upon the conversion of outstanding preferred stock; and 2,430,127 shares of common stock issued or issuable in connection with the exercise of outstanding stock options. Our common stock is traded on the NYSE under the symbol “UDR.”

UNDERWRITING (CONFLICT OF INTEREST)

Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC are acting as representatives of each of the underwriters named below. Subject to the terms and conditions set forth in an underwriting agreement among us and the underwriters, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the number of shares of common stock set forth opposite its name below.


	Underwriter	Number of Shares
Merrill Lynch, Pierce, Fenner & Smith Incorporated
J.P. Morgan Securities LLC


	Total		19,000,000

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the shares sold under the underwriting agreement if any of these shares are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated.

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

The underwriters are offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the shares, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Commissions and Discounts

The representatives have advised us that the underwriters propose initially to offer the shares to the public at the public offering price set forth on the cover page of this prospectus supplement and to dealers at that price less a concession not in excess of $ per share. After the initial offering, the public offering price, concession or any other term of the offering may be changed.

The following table shows the public offering price, underwriting discount and proceeds before expenses to us. The information assumes either no exercise or full exercise by the underwriters of their option to purchase additional shares.


	Per Share	Without Option	With Option
Public offering price	$	$	$
Underwriting discount	$	$	$
Proceeds, before expenses, to us	$	$	$

The expenses of the offering, not including the underwriting discount, are estimated at $ and are payable by us.

S-8

Option Shares

We have granted an option to the underwriters, exercisable for 30 days after the date of this prospectus supplement, to purchase up to 2,850,000 additional shares at the public offering price, less the underwriting discount. If the underwriters exercise this option, each will be obligated, subject to conditions contained in the underwriting agreement, to purchase a number of additional shares proportionate to that underwriter’s initial amount reflected in the table above.

No Sales of Similar Securities

We have agreed for a period ending 60 days after the date of the underwriting agreement, with certain exceptions, not to (i) offer, pledge, sell, contract to sell, solicit offers to purchase, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by us or any of our affiliates or any person in privity with our company or any of our affiliates), directly or indirectly, or announce the offering of any shares of any class of our common stock or any securities convertible into, or exercisable or exchangeable for shares of any class of our common stock (whether such shares or any such securities are now owned or hereafter acquired) or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of shares of any class of our capital stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of shares of any class of our capital stock or such other securities, in cash or otherwise, without the prior written consent of the representatives.

Certain of our officers and our directors have agreed for a period ending 60 days after the date of the underwriting agreement, with certain exceptions including transfers to immediate family members and certain trusts by gift, will, intestate succession or domestic relations order or sales pursuant to pre-existing Rule 10b5-1 plans, not to sell, solicit offers to purchase, pledge or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by such officer or director or any affiliate of the officer or director or any person in privity with the officer or director or any affiliate of the officer or director), directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Securities and Exchange Commission, or the SEC, in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act and the rules and regulations of the SEC promulgated thereunder with respect to, any shares of capital stock of the Company or any securities convertible or exercisable or exchangeable for such capital stock, or publicly announce an intention to effect any such transaction, without the prior written consent of the representatives.

New York Stock Exchange Listing

Our shares are listed on the NYSE under the symbol “UDR.”

Price Stabilization, Short Positions

Until the distribution of the shares is completed, SEC rules may limit underwriters and selling group members from bidding for and purchasing our common stock. However, the representatives may engage in transactions that stabilize the price of the common stock, such as bids or purchases to peg, fix or maintain that price.

In connection with the offering, the underwriters may purchase and sell our common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of

S-9

shares than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ option to purchase additional shares described above. The underwriters may close out any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the option granted to them. “Naked” short sales are sales in excess of such option. 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 our common stock in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of shares of common stock made by the underwriters in the open market prior to the completion of the offering.

Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. The underwriters may conduct these transactions on the NYSE, in the over-the-counter market or otherwise.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we nor any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Electronic Offer, Sale and Distribution of Shares

In connection with the offering, certain of the underwriters or securities dealers may distribute prospectuses by electronic means, such as e-mail. In addition, Merrill Lynch, Pierce, Fenner & Smith Incorporated may facilitate Internet distribution for this offering to certain of its Internet subscription customers. Merrill Lynch, Pierce, Fenner & Smith Incorporated may allocate a limited number of shares for sale to its online brokerage customers. An electronic prospectus is available on the Internet web site maintained by Merrill Lynch, Pierce, Fenner & Smith Incorporated. Other than the prospectus in electronic format, the information on the Merrill Lynch, Pierce, Fenner & Smith Incorporated web site is not part of this prospectus.

Conflict of Interest

As described above under “Use of Proceeds,” a portion of the net proceeds of this offering will be used to repay amounts outstanding under our unsecured credit facility. Banking affiliates of Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC are lenders under our unsecured credit facility. Because affiliates of the underwriters are lenders under our unsecured credit facility, certain of the underwriters or their affiliates may receive more than 5% of the proceeds of this offering. Nonetheless, in accordance with Rule 5121 of the Financial Industry Regulatory Authority, Inc., the appointment of a qualified independent underwriter is not necessary in connection with this offering because, as a REIT, we are excluded from that requirement.

Other Relationships

Some of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions.

In addition, in the ordinary course of their business activities, the underwriters and their 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. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

S-10

Each of the underwriters may arrange to sell the shares offered hereby in certain jurisdictions outside the United States, either directly or through affiliates, where they are permitted to do so.

Each person in a Relevant Member State who initially acquires any shares or to whom any offer is made will be deemed to have represented, acknowledged and agreed that (A) it is a “qualified investor” within the meaning of the law in that Relevant Member State implementing Article 2(1)(e) of the Prospectus Directive, and (B) in the case of any shares acquired by it as a financial intermediary, as that term is used in Article 3(2) of the Prospectus Directive, the shares acquired by it in the offering have not been acquired on behalf of, nor have they been acquired with a view to their offer or resale to, persons in any Relevant Member State other than “qualified investors” as defined in the Prospectus Directive, or in circumstances in which the prior consent of the representatives has been given to the offer or resale. In the case of any shares being offered to a financial intermediary as that term is used in Article 3(2) of the Prospectus Directive, each such financial intermediary will be deemed to have represented, acknowledged and agreed that the shares acquired by it in the offer have not been acquired on a non-discretionary basis on behalf of, nor have they been acquired with a view to their offer or resale to, persons in circumstances which may give rise to an offer of any shares to the public other than their offer or resale in a Relevant Member State to qualified investors as so defined or in circumstances in which the prior consent of the representatives has been obtained to each such proposed offer or resale.

The Company, the representatives and their affiliates will rely upon the truth and accuracy of the foregoing representation, acknowledgement and agreement.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission (the “SEC”) using a “shelf” registration process. Under the shelf process, we may sell any combination of the securities described in this prospectus in one or more offerings.

This prospectus only provides you with a general description of the securities we may offer. Each time we sell securities, we will provide a supplement to this prospectus that will contain specific information about the terms of that offering, including the specific amounts, prices and terms of the securities offered. The prospectus supplement may also add, update or change information contained in this prospectus. You should carefully read both this prospectus and any accompanying prospectus supplement or other offering materials, together with the additional information described under the heading “Where You Can Find More Information.”

You should rely only on the information contained or incorporated by reference in this prospectus. We have not authorized anyone to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. We are not making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted.

This prospectus and any accompanying prospectus supplement or other offering materials do not contain all of the information included in the registration statement as permitted by the rules and regulations of the SEC. For further information, we refer you to the registration statement on Form S-3, including its exhibits. We are subject to the informational requirements of the Securities Exchange Act of 1934, as amended (“Exchange Act”), and, therefore, file reports and other information with the SEC. Statements contained in this prospectus and any accompanying prospectus supplement or other offering materials about the provisions or contents of any agreement or other document are only summaries. If SEC rules require that any agreement or document be filed as an exhibit to the registration statement, you should refer to that agreement or document for its complete contents.

You should not assume that the information in this prospectus, any prospectus supplement or any other offering materials is accurate as of any date other than the date on the front of each document. Our business, financial condition, results of operations and prospects may have changed since then.

In this prospectus, unless otherwise specified or the context requires otherwise, we use the terms “UDR,” the “Company,” “we,” “us” and “our” to refer to UDR, Inc., and the term “Operating Partnership” to refer to United Dominion Realty, L.P.

OUR COMPANY

We are a self-administered real estate investment trust, or REIT, that owns, acquires, renovates, develops and manages apartment communities nationwide. As of June 30, 2011, our consolidated apartment portfolio included 48,556 homes located in 25 markets, with a total of 23,693 completed apartment homes, which are held through the Operating Partnership, together with its consolidated subsidiaries, our subsidiaries and our consolidated joint ventures. In addition, we have an ownership interest in 10,650 homes including 9,891 completed apartment homes through unconsolidated joint ventures. At June 30, 2011, the Operating Partnership’s consolidated apartment portfolio included 80 communities located in 21 markets.

We have elected to be taxed as a REIT under the applicable provisions of the Internal Revenue Code of 1986, or the “Internal Revenue Code.” To continue to qualify as a REIT under the Internal Revenue Code, we must continue to meet certain tests which, among other things, generally require that our assets consist primarily of real estate assets, our income be derived primarily from real estate assets, and that we distribute at least 90% of our REIT taxable income (other than our net capital gain) to our stockholders. As a qualified REIT, we generally will not be subject to U.S. federal income taxes on our REIT taxable income to the extent we distribute such income to our stockholders.

We were formed in 1972 as a Virginia corporation and reincorporated in the State of Maryland in June 2003. The Operating Partnership was formed in 2004 as a Delaware limited partnership. The Operating Partnership is the successor-in-interest to United Dominion Realty, L.P., a limited partnership formed under the laws of Virginia, which commenced operations in 1995. Our principal offices are located at 1745 Shea Center Drive, Suite 200, Highlands Ranch, Colorado 80129 and our telephone number at that address is (720) 283-6120. Our website address is www.udr.com. The information on, or accessible through, our website is not part of this prospectus and should not be relied upon in connection with making any investment decision with respect to the securities offered by this prospectus.

Additional information regarding UDR and the Operating Partnership is set forth in documents on file with the SEC and incorporated by reference in this prospectus and any accompanying prospectus supplement, as described in the section of this prospectus entitled “Where You Can Find More Information.”

RISK FACTORS

You should consider the specific risks described in our Annual Report on Form 10-K for the year ended December 31, 2010, our Quarterly Report on Form 10-Q for the quarter ended June 30, 2011, the risk factors described under the caption “Risk Factors” in any applicable prospectus supplement and any risk factors set forth in our other filings with the SEC, pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act, before making an investment decision. Each of the risks described in these documents could materially and adversely affect our business, financial condition, results of operations and prospects, and could result in a partial or complete loss of your investment. See “Where You Can Find More Information” beginning on page 52 of this prospectus.

USE OF PROCEEDS

Unless we state otherwise in the applicable prospectus supplement, we intend to use the net proceeds from the sale of the securities offered by this prospectus and the accompanying prospectus supplement for general corporate purposes. General corporate purposes may include additions to working capital, capital expenditures, repayment of debt, funding improvements to properties, and acquiring and developing additional properties. Pending application of the net proceeds, we intend to invest the proceeds in interest bearing accounts and short-term, interest bearing securities. Unless otherwise set forth in a prospectus supplement, we will not receive any proceeds in the event that the securities are sold by a selling security holder.

Common Stock

We have one class of common stock. All holders of our common stock are entitled to the same rights and privileges, as described below.

Voting Rights. Holders of our common stock are entitled to one vote per share with respect to each matter presented to our stockholders on which the holders of common stock are entitled to vote and do not have cumulative voting rights. An election of directors by our stockholders is determined by a plurality of the votes cast by the stockholders entitled to vote on the election.

Dividends. Holders of our common stock are entitled to receive proportionately any dividends as may be declared by our board of directors, subject to any preferential dividend rights of outstanding preferred stock.

Liquidation and Dissolution. In the event of our liquidation or dissolution, the holders of our common stock are entitled to receive ratably all assets available for distribution to stockholders after the payment of all debts and other liabilities and subject to the prior rights of any outstanding preferred stock.

Other Rights. Holders of our common stock have no preemptive, subscription, redemption or conversion rights. The rights, preferences and privileges of holders of our common stock are subject to and may be adversely affected by the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.

Restrictions on Ownership and Transfer. Our charter contains ownership and transfer restrictions relating to our stock that are designed primarily to preserve our status as a REIT. These restrictions include but are not limited to the following:

•

no person may beneficially own or constructively own shares of our outstanding “equity stock” (defined as stock that is either common stock or preferred stock) with a value in excess of 9.9% of the value of all outstanding equity stock unless our board of directors exempts the person from such ownership limitation, provided that any such exemption shall not allow the person to exceed 13% of the value of our outstanding equity stock;

•

any transfer that, if effective, would result in any person beneficially owning or constructively owning equity stock with a value in excess of 9.9% of the value of all outstanding equity stock (or such higher value not to exceed 13% as determined pursuant to an exemption from our board of directors) shall be void as to the transfer of that number of shares of equity stock which would otherwise be beneficially owned or constructively owned by such person in excess of such ownership limit; and the intended transferee shall acquire no rights in such excess shares of equity stock;

•

except as provided in the charter, any transfer that, if effective, would result in the equity stock being beneficially owned by fewer than 100 persons shall be void as to the transfer of that number of shares which would be otherwise beneficially owned or constructively owned by the transferee; and the intended transferee shall acquire no rights in such excess shares of equity stock; and

•

any transfer of shares of equity stock that, if effective, would result in us being “closely held” within the meaning of Section 856(h) of the Internal Revenue Code shall be void as to the transfer of that number of shares of equity stock which would cause us to be “closely held” within the meaning of Section 856(h) of the Internal Revenue Code; and the intended transferee shall acquire no rights in such excess shares of equity stock.

Listing. Our common stock is listed on the NYSE under the symbol “UDR.”

Our board of directors may authorize the issuance of preferred stock in one or more series and may determine, with respect to any such series, the powers, preferences and rights of such series, and its qualifications, limitations and restrictions. We currently have three designated series of Preferred Stock that are outstanding or could be issued.

•

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

any additional rights, preferences, qualifications, limitations and restrictions of the series.

Upon issuance, the shares of preferred stock will be fully paid and nonassessable, which means that its holders will have paid their purchase price in full, and we may not require them to pay additional funds. Holders of preferred stock will not have any preemptive rights.

Series E Preferred Stock

Ranking. The Series E Preferred Stock ranks pari passu with the Series G Preferred Stock and any of our other capital stock designated as ranking on parity with the Series E Preferred Stock and the Series G Preferred Stock (collectively, “Parity Stock”), with respect to payment of dividends and amounts upon liquidation, dissolution or winding up, and senior to our common stock, the Series F Preferred Stock and any other class of our capital stock now or hereafter issued and outstanding that ranks junior as to the payment of dividends or amounts upon liquidation, dissolution and winding up to the Series E Preferred Stock or any Parity Stock (collectively, “Junior Stock”). While any shares of Series E Preferred Stock are outstanding, we may not authorize or create any class or series of capital stock that ranks senior to the Series E Preferred Stock with respect to the payment of dividends or amounts upon liquidation, dissolution or winding up, or reclassify any of our authorized capital stock into any such shares, or create, authorize or issue any obligation or security convertible into or evidencing the right to purchase any such shares, without the consent of the holders of a majority of the outstanding Series E Preferred Stock.

Dividends. Holders of the Series E Preferred Stock are entitled to receive, out of funds legally available for payment, cumulative preferential cash dividends at an annual rate of 8% of the liquidation preference (equivalent to $1.3288 per share of Series E Preferred Stock), until such time as the dividend on the common stock is equal to or exceeds this amount for four consecutive calendar quarters, at which time the dividends will adjust to match the dividend on the common stock. Dividends on each share of Series E Preferred Stock accrue and are cumulative from and including the date of original issue and are paid quarterly in arrears on the last day, or the next business day, of January, April, July and October, commencing July 31, 2003. Dividends on each share of Series E Preferred Stock are cumulative to the extent not declared and paid in full whether or not there exists funds legally available for the payment of such dividends or such dividends have been authorized.

Accumulations of dividends on the Series E Preferred Stock do not bear interest and holders of the Series E Preferred Stock are not entitled to any dividends in excess of full cumulative dividends. Dividends payable on the Series E Preferred Stock for any partial dividend period will be computed on the basis of a 360-day year consisting of twelve 30-day months. Dividends payable on the Series E Preferred Stock for each full dividend period are computed by dividing the annual dividend rate by four.

Until such time as the dividend on the common stock is equal to or exceeds $1.3288 per share per annum for four consecutive calendar quarters, no dividend (other than in Junior Stock) will be declared or paid on any Junior Stock unless full cumulative dividends have been declared and paid or are contemporaneously declared and funds sufficient for payment set aside on the Series E Preferred Stock for all prior dividend periods, nor shall any Junior Stock or any Parity Stock be redeemed, purchased or otherwise acquired for any consideration (or any moneys paid to or made available for a sinking fund for redemption of any shares of Junior Stock or Parity Stock) (except by conversion into or exchange for other Junior Stock or Parity Stock).

We may not declare, pay or set apart funds for the payment of any dividend on share of Series E Preferred Stock at such time as the terms and provisions of any agreement to which we are bound, including any agreement relating to out indebtedness, prohibits such declaration, payment or setting apart for payment or provides that such declaration, payment or setting apart for payment would constitute a breach or a default under such an agreement, or if such declaration or payment is restricted or prohibited by law.

Liquidation Preference. The holders of Series E Preferred Stock are entitled to receive in the event of any liquidation, dissolution or winding up of UDR, whether voluntary or involuntary, $16.61 per share of Series E Preferred Stock, which we refer to in this prospectus as the “Series E Liquidation Preference,” plus an amount per share of Series E Preferred Stock equal to all dividends (whether or not earned or declared) accrued and unpaid thereon to, but not including, the date of final distribution to such holders. If, upon any liquidation, dissolution or winding up of UDR, the Series E Liquidation Preference and any amounts payable as a liquidation preference to other shares of Parity Stock are not paid in full, the holders of the shares of the Series E Preferred Stock and any such Parity Stock will share ratably in the distribution of our assets in proportion to the full respective liquidation preferences to which they are entitled.

Voting Rights. The holders of our outstanding Series E Preferred Stock are entitled to vote on an “as converted” (one-for-one) basis as a single class in combination with the holders of our common stock at any meeting of stockholders for the election of directors or for any other purpose on which holders of our common stock are entitled to vote.

Conversion Rights. Each share of the Series E Preferred Stock is convertible into one share of common stock, subject to adjustment for (a) capital reorganization or reclassification, (b) a merger, consolidation, statutory share exchange, self tender offer for all or substantially all of the outstanding shares of our common stock or sale of all or substantially all of our assets or (c) a dividend or other distribution payable in securities issued by us. No fractional shares will be issued upon conversion of the Series E Preferred Stock. In lieu of issuing fractional shares that would otherwise be deliverable upon the conversion of one share of Series E Preferred Stock, we will pay to the holder of such share an amount in cash equal to such fraction multiplied by the closing sale price on the trading day immediately preceding the date of conversion.

If after the original date of issue we make or issue, or fix a record date for the holders of our common stock entitled to receive, a dividend or other distribution payable in securities issued by us, then and in each event, we shall make such provision so that each holder of Series E Preferred Stock will be entitled to receive, upon conversion of the Series E Preferred Stock, in addition to the shares of our common stock receivable upon conversion, such number of such securities as such holder would have received if the holder had converted the Series E Preferred Stock immediately prior to the date of such event and had continued to hold such securities until the conversion date.

Listing. The Series E Preferred Stock is not listed on any exchange.

Transfer Agent, Registrar, Dividend Disbursing Agent and Redemption Agent. The transfer agent, registrar, dividend disbursing agent and redemption agent for the Series E Preferred Stock is Wells Fargo Bank, N.A., South St. Paul, Minnesota.

Series F Preferred Stock

No Dividends or Liquidation Rights. The Series F Preferred Stock is not entitled to receive dividends or otherwise participate in our earnings or assets. Upon a voluntary or involuntary dissolution, liquidation or winding up, the holders of shares of the Series F Preferred Stock then outstanding will not be entitled to receive or be paid out of the assets of the corporation legally available for distribution to its stockholders. The holders of the Series F Preferred Stock as such will have no right or claim to any of our assets.

Voting Rights. Except as otherwise required by law or provided in our charter, and subject to the express terms of any other series of Preferred Stock, each share of Series F Preferred Stock will entitle the holder thereof to one vote for each share of Series F Preferred Stock held by such holder on each matter submitted to a vote at a meeting of the stockholders upon which holders of common stock are entitled to vote. The holders of Series F Preferred Stock will be entitled to receive notice of all meetings of the stockholders at which the holders of common stock are entitled to such notice.

Conversion Rights. The Series F Preferred Stock is not convertible into or exchangeable for any other property or securities of the corporation.

Redemption. Each share of Series F Preferred Stock will automatically be redeemed by UDR for no consideration without notice to its holder and without further action by UDR if either (A) the Partnership Unit (as defined in that certain Amended and Restated Agreement of Limited Partnership of United Dominion Realty, L.P., dated as of February 23, 2004) or (B) the Limited Partnership Interest (as defined in that certain Second Amended and Restated Agreement of Limited Partnership of Heritage Communities L.P., dated as of September 18, 1997) underlying such share of Series F Preferred Stock is no longer outstanding.

Series G Preferred Stock

Ranking. The Series G Preferred Stock ranks senior to the Junior Stock, including shares of our common stock and the Series F Preferred Stock, with respect to payment of dividends and amounts upon liquidation, dissolution or winding up. While any shares of Series G Preferred Stock are outstanding, we may not authorize or create any class or series of capital stock that ranks senior to the Series G Preferred Stock with respect to the payment of dividends or amounts upon liquidation, dissolution or winding up without the consent of the holders of two-thirds of the outstanding Series G Preferred Stock voting as a single class. However, we may create additional classes or series of stock, amend our charter to increase the authorized number of shares of preferred stock or issue series of Parity Stock without the consent of any holder of Series G Preferred Stock.

Dividends. Holders of Series G Preferred Stock are entitled to receive, when, as and if authorized by our board of directors, out of funds legally available for payment, and declared by us, cumulative cash dividends at the annual rate of 6.75% per share of its liquidation preference (equivalent to $1.6875 per annum per share of Series G Preferred Stock). However, if following a “change of control” (as defined below), the Series G Preferred Stock is not listed on the NYSE or the NYSE AMEX or quoted on NASDAQ (or listed or quoted on a successor exchange or quotation system), holders of the Series G Preferred Stock will be entitled to receive, when and as authorized by our board of directors and declared by us, out of funds legally available for the payment of dividends, cumulative cash dividends from, but not including, the first date on which both the change of control has occurred and the Series G Preferred Stock is not so listed or quoted at the increased annual rate of 7.75% of its liquidation preference, equivalent to $1.9375 per annum per share of Series G Preferred Stock for as long as the Series G Preferred Stock is not so listed or quoted. Dividends on each share of Series G Preferred Stock are cumulative from the date of original issue and are payable quarterly in arrears on or about the 30th of each January, April, July and October, commencing on or about July 30, 2007 at the then applicable annual rate. Each dividend is payable to holders of record as they appear on our stock records at the close of business on the record date, not exceeding 30 days preceding the payment dates thereof, as fixed by our board of directors. Dividends are cumulative from the most recent dividend payment date to which dividends have been paid, whether or not in any dividend period or periods there shall be funds legally available for the payment of such dividends. Accumulations of dividends on the Series G Preferred Stock do not bear interest and holders of the Series G Preferred Stock are not entitled to any dividends in excess of full cumulative dividends. Dividends

payable on the Series G Preferred Stock for any period greater or less than a full dividend period will be computed on the basis of a 360-day year consisting of twelve 30-day months. Dividends payable on the Series G Preferred Stock for each full dividend period are computed by dividing the annual dividend rate by four.

No dividend will be declared or paid on any Parity Stock unless full cumulative dividends have been declared and paid or are contemporaneously declared and funds sufficient for payment set aside on the Series G Preferred Stock for all prior dividend periods; provided, however, that if accrued dividends on the Series G Preferred Stock for all prior dividend periods have not been paid in full or a sum sufficient for such payment is not set apart, then any dividend declared on the Series G Preferred Stock for any dividend period and on any Parity Stock will be declared ratably in proportion to accrued and unpaid dividends on the Series G Preferred Stock and such Parity Stock. All of our dividends on the Series G Preferred Stock, including any capital gain dividends, will be credited first to the earliest accrued and unpaid dividend date.

We may not (i) declare, pay or set apart funds for the payment of any dividend or other distribution with respect to any Junior Stock (other than a dividend or distribution payable in Junior Stock) or (ii) redeem, purchase or otherwise acquire for consideration any Junior Stock through a sinking fund or otherwise (other than a redemption or purchase or other acquisition of shares of common stock made for purposes of an employee incentive or benefit plan of UDR or any subsidiary, or a conversion into or exchange for Junior Stock or redemptions for the purpose of preserving our qualification as a REIT), unless all cumulative dividends with respect to the Series G Preferred Stock and any Parity Stock at the time such dividends are payable have been paid or funds have been set apart for payment of such dividends.

As used herein, the term “dividend” does not include dividends payable solely in Junior Stock on Junior Stock, or in options, warrants or rights to holders of Junior Stock to subscribe for or purchase any Junior Stock.

A “change of control” shall be deemed to have occurred at such time as (i) the date a “person” or “group” (within the meaning of Sections 13(d) and 14(d) of the Exchange Act) becomes the ultimate “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act, except that a person or group shall be deemed to have beneficial ownership of all shares of voting stock that such person or group has the right to acquire regardless of when such right is first exercisable), directly or indirectly, of voting stock representing more than 50% of the total voting power of our total voting stock; (ii) the date we sell, transfer or otherwise dispose of all or substantially all of our assets; or (iii) the date of the consummation of a merger or stock exchange of our company with another entity where our stockholders immediately prior to the merger or stock exchange would not beneficially own, immediately after the merger or stock exchange, shares representing 50% or more of all votes (without consideration of the rights of any class of stock to elect directors by a separate group vote) to which all stockholders of the corporation issuing cash or securities in the merger or stock exchange would be entitled in the election of directors, or where members of our board of directors immediately prior to the merger or stock exchange would not immediately after the merger or stock exchange constitute a majority of the board of directors of the corporation issuing cash or securities in the merger or stock exchange. “Voting stock” shall mean stock of any class or kind having the power to vote generally in the election of directors.

Redemption. We may not redeem the Series G Preferred Stock prior to May 31, 2012, except in certain limited circumstances relating to the ownership limitation necessary to preserve our qualification as a REIT or at any time the Series G Preferred Stock is not listed on the NYSE or the American Stock Exchange or quoted on NASDAQ (or listed or quoted on a successor exchange or quotation service) following a “change of control.” On or after May 31, 2012, we, at our option, may redeem the Series G Preferred Stock, in whole, at any time, or in part, from time to time, for cash at a redemption price of $25.00 per share, plus all accrued and unpaid dividends thereon to, but not including, the date fixed for redemption, without interest. If at any time following a change of control, the Series G Preferred Stock is not listed on the NYSE or the American Stock Exchange or quoted on NASDAQ (or listed or quoted on a successor exchange or quotation service), we will have the option to redeem the Series G Preferred Stock, in whole but not in part, within 90 days after the first date on which both the change of control has occurred and the Series G Preferred Stock is not so listed or quoted, for cash at $25.00 per share plus accrued and unpaid dividends (whether or not declared) to, but not including, the date of redemption.

On the redemption date, we must pay on each share of Series G Preferred Stock to be redeemed any accrued and unpaid dividends, in arrears, for any dividend period ending on or prior to the redemption date. In the case of a redemption date falling after a dividend payment record date and prior to the related payment date, the holders of Series G Preferred Stock at the close of business on such record date will be entitled to receive the dividend payable on such shares on the corresponding dividend payment date, notwithstanding the redemption of such shares prior to such dividend payment date. Except as provided for in the two preceding sentences, no payment or allowance will be made for unpaid dividends, whether or not in arrears, on any Series G Preferred Stock called for redemption.

If full cumulative dividends on the Series G Preferred Stock and any Parity Stock have not been paid or declared and set apart for payment, the Series G Preferred Stock may not be redeemed in part and we may not purchase, redeem or otherwise acquire Series G Preferred Stock or any Parity Stock other than in exchange for Junior Stock; provided, however, that the foregoing shall not prevent the purchase by us of shares held in excess of the limits in our charter in order to ensure that we continue to meet the requirements for qualification as a REIT.

On and after the date fixed for redemption, dividends will cease to accrue on the shares of Series G Preferred Stock called for redemption (except that, in the case of a redemption date after a dividend payment record date and prior to the related payment date, holders of Series G Preferred Stock on the dividend payment record date will be entitled on such dividend payment date to receive the dividend payable on such shares on the corresponding dividend payment date), such shares shall no longer be deemed to be outstanding and all rights of the holders of such shares as holders of Series G Preferred Stock shall cease except the right to receive the cash payable upon such redemption, without interest from the date of such redemption.

Liquidation Preference. The holders of Series G Preferred Stock will be entitled to receive in the event of any liquidation, dissolution or winding up of UDR, whether voluntary or involuntary, $25.00 per share of Series G Preferred Stock, which we refer to in this prospectus as the “Series G Liquidation Preference,” plus an amount per share of Series G Preferred Stock equal to all dividends (whether or not earned or declared) accrued and unpaid thereon to, but not including, the date of final distribution to such holders.

Until the holders of Series G Preferred Stock have been paid the Series G Liquidation Preference and all accrued and unpaid dividends in full, no payment will be made to any holder of Junior Stock upon the liquidation, dissolution or winding up of UDR. If, upon any liquidation, dissolution or winding up of UDR, our assets, or proceeds thereof, distributable among the holders of the Series G Preferred Stock are insufficient to pay in full the Series G Liquidation Preference and all accrued and unpaid dividends and the liquidation preference and all accrued and unpaid dividends with respect to any other shares of Parity Stock, then such assets, or the proceeds thereof, will be distributed among the holders of Series G Preferred Stock and any such Parity Stock ratably in accordance with the respective amounts that would be payable on such Series G Preferred Stock and any such Parity Stock if all amounts payable thereon were paid in full. None of (i) a consolidation or merger of UDR with one or more entities, (ii) a statutory stock exchange by UDR or (iii) a sale or transfer of all or substantially all of our assets will be considered a liquidation, dissolution or winding up, voluntary or involuntary, of UDR.

Voting Rights. Except as indicated below, the holders of Series G Preferred Stock will have no voting rights. If and whenever six quarterly dividends (whether or not consecutive) payable on the Series G Preferred Stock are in arrears, whether or not earned or declared, the number of members then constituting our board of directors will be increased by two and the holders of Series G Preferred Stock, voting together as a class with the holders of any other series of Parity Stock upon which like voting rights have been conferred and are exercisable (any such other series, the “Voting Preferred Shares”), will have the right to elect two additional board members at an annual meeting of stockholders or a properly called special meeting of the holders of the Series G Preferred Stock and such Voting Preferred Shares and at each subsequent annual meeting of stockholders until all such dividends and dividends for the then current quarterly period on the Series G Preferred Stock and such other Voting Preferred Shares have been paid or declared and set aside for payment. Whenever all arrears in dividends on the Series G Preferred Stock and the Voting Preferred Shares then outstanding have been paid and full dividends on the Series G Preferred Stock and the Voting Preferred Shares for the then current quarterly dividend period have been paid in full or declared and set apart for payment in full, then the right of the holders of the

Series G Preferred Stock and the Voting Preferred Shares to elect two additional board members will cease, the terms of office of the board members will forthwith terminate and the number of members of the board of directors will be reduced accordingly. However, the right of the holders of the Series G Preferred Stock and the Voting Preferred Shares to elect the additional board members will again vest if and whenever six quarterly dividends are in arrears, as described above. In no event shall the holders of Series G Preferred Stock be entitled pursuant to these voting rights to elect a director that would cause us to fail to satisfy a requirement relating to director independence of any national securities exchange on which any class or series of our stock is listed.

In addition, the approval of two-thirds of the votes entitled to be cast by the holders of outstanding Series G Preferred Stock, voting separately as a class, either at a meeting of stockholders or by written consent, is required (i) to amend, alter or repeal any provisions of our charter or the Articles Supplementary relating to the Series G Preferred Stock, whether by merger, consolidation or otherwise, to affect materially and adversely the voting powers, rights or preferences of the holders of the Series G Preferred Stock, unless in connection with any such amendment, alteration or repeal, the Series G Preferred Stock remains outstanding without the terms thereof being materially changed in any respect adverse to the holders thereof or is converted into or exchanged for preferred stock of the surviving entity having preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends, qualifications and terms and conditions of redemption thereof that are substantially similar to those of the Series G Preferred Stock, or (ii) to authorize, create, or increase the authorized amount of any class or series of capital stock having rights senior to the Series G Preferred Stock with respect to the payment of dividends or amounts upon liquidation, dissolution or winding up (provided that if such amendment affects materially and adversely the rights, preferences, privileges or voting powers of one or more but not all of the other series of Voting Preferred Shares, the consent of the holders of at least two-thirds of the outstanding shares of each such series so affected is required). However, we may create additional classes of Parity Stock and Junior Stock, amend our charter to increase the authorized number of shares of Parity Stock (including the Series G Preferred Stock) and Junior Stock and issue additional series of Parity Stock and Junior Stock without the consent of any holder of Series G Preferred Stock.

Conversion Rights. The Series G Preferred Stock is not convertible into or exchangeable for any other property or any other securities except as set forth in Article VI of our charter dealing with restrictions on ownership and transfer in connection with the preservation of our REIT status.

Listing. The Series G Preferred Stock is listed on the NYSE under the symbol “UDRPrG.”

Transfer Agent, Registrar, Dividend Disbursing Agent and Redemption Agent. The transfer agent, registrar, dividend disbursing agent and redemption agent for the Series G Preferred Stock is Wells Fargo Bank, N.A., South St. Paul, Minnesota.

Anti-takeover Effects of Our Bylaws and Maryland Law

Our bylaws and Maryland law contain provisions that could have the effect of delaying, deferring or discouraging another party from acquiring control of us. These provisions, which are summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors.

Bylaws. Our bylaws establish an advance written notice procedure for stockholders seeking to nominate candidates for election as directors at any annual meeting of stockholders and to bring business before an annual meeting of our stockholders. Our bylaws provide that only persons who are nominated by our board of directors or by a stockholder who has given timely written notice to our secretary before the meeting to elect directors will be eligible for election as our directors. Our bylaws also provide that any matter to be presented at any meeting of stockholders must be presented either by our board of directors or by a stockholder in compliance with the procedures in our bylaws. A stockholder must give timely written notice to our secretary of its intention to present a matter before an annual meeting of stockholders. Our board of directors then will consider whether the matter is one that is appropriate for consideration by our stockholders under the Maryland General Corporation Law and the SEC’s rules.

Certain Maryland Law Provisions. As a Maryland corporation, we are subject to certain restrictions concerning certain “business combinations” (including a merger, consolidation, share exchange or, in certain circumstances, an asset transfer or issuance or reclassification of equity securities) between us and an “interested stockholder.” Interested stockholders are persons: (i) who beneficially own 10% or more of the voting power of our outstanding voting stock, or (ii) who are affiliates or associates of us who, at any time within the two-year period prior to the date in question, were the beneficial owners of 10% or more of the voting power of our outstanding stock. Such business combinations are prohibited for five years after the most recent date on which the interested stockholder became an interested stockholder. Thereafter, any such business combination must be recommended by the board of directors and approved by the affirmative vote of at least: (i) 80% of the votes entitled to be cast by holders of the outstanding voting shares voting together as a single voting group, and (ii) two-thirds of the votes entitled to be cast by holders of the outstanding voting shares other than voting shares held by the interested stockholder or an affiliate or associate of the interested stockholder with whom the business combination is to be effected, unless, among other things, the corporation’s stockholders receive a minimum price for their shares and the consideration is received in the form of cash or other consideration in the same form as previously paid by the interested stockholder for its shares. These provisions of Maryland law do not apply, however, to business combinations that are approved or exempted by the board of directors prior to the time that the interested stockholder becomes an interested stockholder.

Also under Maryland law, “control shares” of a Maryland corporation acquired in a “control share acquisition” have no voting rights except to the extent approved by a vote of two-thirds of the votes entitled to be cast on the matter, excluding shares owned by the acquirer or by officers or directors who are employees of the corporation. “Control shares” are shares of stock which, if aggregated with all other shares of stock owned by the acquirer or shares of stock for which the acquirer is able to exercise or direct the exercise of voting power except solely by virtue of a revocable proxy, would entitle the acquirer to exercise voting power in electing directors within one of the following ranges of voting power:

•

one-tenth or more but less than one-third,

•

one-third or more but less than a majority, or

•

a majority or more of all voting power.

Control shares do not include shares the acquiring person is then entitled to vote as a result of having previously obtained stockholder approval. A “control share acquisition” means, subject to certain exceptions, the acquisition of, ownership of or the power to direct the exercise of voting power with respect to, control shares.

The control share acquisition statute does not apply to shares acquired in a merger, consolidation or share exchange if the corporation is a party to the transaction or to acquisitions approved or exempted by the charter or bylaws of the corporation. Our bylaws contain a provision exempting from the control share acquisition statute any acquisitions by any person of shares of our stock.

Under Title 3, Subtitle 8 of the Maryland General Corporation Law, a Maryland corporation that has a class of equity securities registered under the Securities Exchange Act of 1934 and that has at least three directors who are not officers or employees of the corporation, are not acquiring persons, are not directors, officers, affiliates or associates of any acquiring person, or are not nominated or designated as a director by an acquiring person, may elect in its charter or bylaws or by resolution of its board of directors to be subject to certain provisions of Subtitle 8 that may have the effect of delaying or preventing a change in control of the corporation. These provisions relate to a classified board of directors, removal of directors, establishing the number of directors, filling vacancies on the board of directors and calling special meetings of the corporation’s stockholders. We have not made the election to be governed by these provisions of Subtitle 8 of the Maryland General Corporation Law. However, our charter and our bylaws permit our board of directors to determine the number of directors subject to a minimum number and other provisions contained in such documents.

The debt securities may be original issue discount securities, which are debt securities that may provide for less than their entire principal amount to be payable upon declaration of acceleration of their maturity. Special U.S. federal income tax, accounting and other considerations applicable to original issue discount securities will be described in the prospectus supplement.

Unless we specify otherwise in the applicable prospectus supplement, we will issue our senior debt securities under an indenture dated as of November 1, 1995, between us and the trustee under the indenture, which is U.S. Bank National Association (successor trustee to Wachovia Bank, National Association, formerly known as First Union National Bank of Virginia). We refer to this indenture as the “Senior Indenture.” Unless we specify otherwise in the applicable prospectus supplement, we will issue our subordinated debt securities under

the indenture dated as of August 1, 1994, between us and the trustee under the indenture, which is U.S. Bank National Association (successor trustee to SunTrust Bank, formerly known as Crestar Bank). We refer to this indenture as the “Subordinated Indenture.” The Senior Indenture and the Subordinated Indenture are sometimes referred to in this prospectus individually as an “Indenture” and collectively as the “Indentures.” As trustees, U.S. Bank serves two roles. First, the trustees can enforce your rights against us if we default on the debt securities. Second, the trustees assist in administering our obligations under the debt securities, such as payments of interest.

Below, we describe the Indentures and summarize some of their provisions. However, we have not described every aspect of the Indentures or the debt securities that we may issue under the Indentures. You should refer to the actual Indentures for a complete description of their provisions and the definitions of terms used in them. In this prospectus, we provide only the definitions for some of the more important terms in the Indentures. Wherever we refer to defined terms of the Indentures in this prospectus or in the prospectus supplement, we are incorporating by reference those defined terms. The Senior Indenture and Subordinated Indenture are exhibits to the registration statement of which this prospectus is a part.

General Terms. The Indentures do not limit the aggregate principal amount of debt securities that we may issue and provide that we may issue debt securities from time to time in one or more series, except that the Senior Indenture contains limitations on the amount of indebtedness that we may incur, as described in more detail below.

The senior debt securities issued under the Senior Indenture will be unsecured obligations and will rank on a parity with all of our other unsecured and unsubordinated indebtedness. The subordinated debt securities issued under the Subordinated Indenture will be our unsecured obligations and will be subordinated in right of payment to all senior debt.

Each Indenture allows for any one or more series of debt securities to have one or more trustees. Any trustee under either Indenture may resign or be removed with respect to one or more series of debt securities, and a successor trustee may be appointed to act with respect to the series. If two or more persons are acting as trustee with respect to different series of debt securities, each trustee will be a trustee of a trust under the applicable Indenture separate and apart from the trust administered by any other trustee. Unless this prospectus or the applicable prospectus supplement states differently, each trustee of a series of debt securities may take any action that we may take under the applicable Indenture.

We will provide you with more information in the applicable prospectus supplement regarding any deletions, modifications or additions to the events of default or covenants that are described below, including any addition of a covenant or other provision.

Denominations, Interest, Registration and Transfer. Unless the applicable prospectus supplement states differently, the debt securities of any series issued under an Indenture in registered form will be issuable in denominations of $1,000 and integral multiples of $1,000. Unless the prospectus supplement states otherwise, the debt securities of any series issued under an Indenture in bearer form will be issuable in denominations of $5,000.

Unless otherwise provided in the applicable prospectus supplement, the trustees will pay the principal of and any premium and interest on the debt securities issued under an Indenture and will register the transfer of any debt securities at their offices. However, at our option, we may distribute interest payments by mailing a check to the address of each holder of debt securities that appears on the register for the debt securities.

Any interest on the debt securities not punctually paid or duly provided for on any interest payment date will cease to be payable to the holder on the applicable regular record date. This defaulted interest may be paid to the person in whose name the debt security is registered at the close of business on a special record date for the payment of the defaulted interest. We will set the special record date and give the holder of the debt security at least 10 days’ prior notice. In the alternative, this defaulted interest may be paid in any other lawful manner, all as more completely described in the applicable Indenture.

Subject to any limitations imposed upon debt securities issued under an Indenture in book-entry form, the debt securities of any series will be exchangeable for other debt securities of the same series and of a like aggregate principal amount and tenor of different authorized denominations upon surrender to the applicable trustee of the debt securities. In addition, subject to any limitations imposed upon debt securities issued under an Indenture in book-entry form, a holder may surrender the debt securities to the trustee for conversion or registration of transfer. Debt securities surrendered for conversion, registration of transfer or exchange will be duly endorsed or accompanied by a written instrument of transfer from the holder. A holder will not have to pay a service charge for any registration of transfer or exchange of any debt securities, but we may require payment of a sum sufficient to cover any applicable tax or other governmental charge.

If the prospectus supplement refers to any transfer agent, in addition to the applicable trustee that we initially designated with respect to any series of debt securities, we may at any time rescind the designation of the transfer agent or approve a change in the location through which the transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the series. We may at any time designate additional transfer agents with respect to any series of debt securities issued under an Indenture.

Neither we nor the trustees under the Indentures will be required to:

issue, register the transfer of or exchange debt securities of any series during a period beginning at the opening of business 15 days before any selection of debt securities of that series to be redeemed and ending at the close of business on the day of mailing of the relevant notice of redemption,

•

register the transfer of or exchange any debt security, or portion thereof, called for redemption, except the unredeemed portion of any debt security being redeemed in part, or

•

issue, register the transfer of or exchange any debt security that has been surrendered for repayment at the holder’s option, except the portion, if any, of the debt security not to be repaid.

Merger, Consolidation or Sale. The Indentures generally provide that we may consolidate with, or sell, lease or convey all or substantially all of our assets to, or merge with or into, any other entity, provided that:

•

either we will be the continuing entity, or the successor entity formed by or resulting from the consolidation or merger or that will have received the transfer of the assets is an entity organized and existing under the laws of the United States or any state and will expressly assume payment of the principal of, and any premium or make-whole amount, if any, and interest on all of the debt securities issued under the Indenture and the due and punctual performance and observance of all of the covenants and conditions contained in the Indenture,

•

immediately after giving effect to the transaction and treating any resulting indebtedness that becomes our or any subsidiary’s obligation as having been incurred by us or the subsidiary at the time of the transaction, no event of default under the Indenture, and no event which, after notice or the lapse of time, or both, would become an event of default, will have occurred and be continuing, and

•

we receive an Officers’ Certificate and legal opinion as to compliance with these conditions.

Covenants Under the Senior Indenture. The Senior Indenture provides that we will not, and will not permit any subsidiary to, incur any Debt (as defined below) if, immediately after giving effect to the incurrence of the additional Debt and the application of the proceeds from the Debt, the aggregate principal amount of all of our outstanding Debt on a consolidated basis determined in accordance with generally accepted accounting principles is greater than 60% of the sum of, without duplication:

•

our Total Assets (as defined below) as of the end of the calendar quarter covered in our Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most recently filed with the SEC, or, if the filing is not permitted under the Exchange Act, with the trustee, prior to the incurrence of the additional Debt, and

•

the purchase price of any real estate assets or mortgages receivable acquired, and the amount of any securities offering proceeds received, to the extent the proceeds were not used to acquire real estate assets or mortgages receivable or used to reduce Debt, by us or any subsidiary since the end of the calendar quarter, including those proceeds obtained in connection with the incurrence of the additional Debt.

In addition to the foregoing limitations on the incurrence of Debt, the Senior Indenture provides that we will not, and will not permit any subsidiary to, incur any Debt secured by any mortgage, lien, charge, pledge, encumbrance or security interest of any kind upon any of our or any subsidiary’s property if, immediately after giving effect to the incurrence of the Debt and the application of the proceeds from the Debt, the aggregate principal amount of all of our outstanding Debt on a consolidated basis that is secured by any mortgage, lien, charge, pledge, encumbrance or security interest on our or any subsidiary’s property is greater than 40% of our Total Assets.

In addition to the foregoing limitations on the incurrence of Debt, the Senior Indenture provides that we will not, and will not permit any subsidiary to, incur any Debt if the ratio of Consolidated Income Available for Debt Service (as defined below) to the Annual Service Charge (as defined below) for the four consecutive fiscal quarters most recently ended prior to the date on which the additional Debt is to be incurred will have been less than 1.5, on a pro forma basis after giving effect to the Debt and to the application of the proceeds from the Debt, and calculated on the assumption that:

•

the Debt and any other Debt incurred since the first day of the four-quarter period and the application of the proceeds therefrom, including to refinance other Debt, had occurred at the beginning of the period,

•

our repayment or retirement of any other Debt since the first day of the four-quarter period had been incurred, repaid or retired at the beginning of the period, except that, in making the computation, the amount of Debt under any revolving credit facility will be computed based upon the average daily balance of the Debt during the period,

•

in the case of Acquired Debt (as defined below) or Debt incurred in connection with any acquisition since the first day of the four-quarter period, the related acquisition had occurred as of the first day of the period with the appropriate adjustments with respect to the acquisition being included in the pro forma calculation, and

•

in the case of our acquisition or disposition of any asset or group of assets since the first day of the four-quarter period, whether by merger, stock purchase or sale, or asset purchase or sale, 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.

The Subordinated Indenture does not limit the incurrence of Debt.

The following terms used in the covenants summarized above have the indicated meanings:

“Acquired Debt” means Debt of a person (i) existing at the time the person becomes a subsidiary or (ii) assumed in connection with the acquisition of assets from the person, in each case, other than Debt incurred in connection with, or in contemplation of, the person becoming a subsidiary or the acquisition. Acquired Debt will be deemed to be incurred on the date of the related acquisition of assets from any person or the date the acquired person becomes a subsidiary.

“Annual Service Charge” as of any date means the maximum amount that is payable in any period for interest on, and original issue discount of, our Debt and the amount of dividends that are payable in respect of any Disqualified Stock (as defined below).

“Capital Stock” means, with respect to any person, any capital stock, including preferred stock, shares, interests, participations or other ownership interests, however designated, of the person and any rights (other than

debt securities convertible into or exchangeable for corporate stock), warrants or options to purchase any capital stock.

“Consolidated Income Available for Debt Service” for any period means Funds From Operations (as defined below) plus amounts that have been deducted for interest on Debt.

“Debt” of UDR or any subsidiary means any indebtedness of UDR, or any subsidiary, whether or not contingent, in respect of, without duplication:

•

borrowed money or evidenced by bonds, notes, debentures or similar instruments,

•

indebtedness secured by any mortgage, pledge, lien, charge, encumbrance or any security interest existing on property owned by UDR or any subsidiary,

•

the reimbursement obligations, contingent or otherwise, in connection with any letters of credit actually issued or amounts representing the balance deferred and unpaid of the purchase price of any property or services, except any balance that constitutes an accrued expense or trade payable, or all conditional sale obligations or obligations under any title retention agreement,

•

the principal amount of all obligations of UDR or any subsidiary with respect to redemption, repayment or other repurchase of any Disqualified Stock, or

•

any lease of property by UDR or any subsidiary as lessee that is reflected on UDR’s consolidated balance sheet as a capitalized lease in accordance with generally accepted accounting principles to the extent, in the case of items of indebtedness under the first three bullet points above, that any of the items, other than letters of credit, would appear as a liability on UDR’s consolidated balance sheet in accordance with generally accepted accounting principles, and also includes, to the extent not otherwise included, any obligation of UDR or any subsidiary to be liable for, or to pay, as obligor, guarantor or otherwise, other than for purposes of collection in the ordinary course of business, debt of another person, other than UDR or any subsidiary.

Debt will be deemed to be incurred by us or any subsidiary whenever we or a subsidiary creates, assumes, guarantees or otherwise becomes liable for that Debt.

“Disqualified Stock” means, with respect to any person, any capital stock of the person that by the terms of the capital stock, or by the terms of any security into which it is convertible or for which it is exchangeable or exercisable, upon the happening of any event or otherwise:

•

matures or is mandatorily redeemable, pursuant to a sinking fund obligation or otherwise,

•

is convertible into or exchangeable or exercisable for Debt or Disqualified Stock, or

•

is redeemable at the option of the holder thereof, in whole or in part, in each case on or prior to the Stated Maturity of the series of debt securities.

“Funds From Operations” for any period means income before gains or losses on investments and extraordinary items plus amounts that have been deducted, and minus amounts that have been added, for the following items, without duplication:

•

provision for preferred stock dividends,

•

provision for property depreciation and amortization, and

•

the effect of any adjustments for significant non-recurring items, including any noncash charge resulting from a change in accounting principles in determining income before gains or losses on investments and extraordinary items for the period, as reflected in our financial statements for the period determined on a consolidated basis in accordance with generally accepted accounting principles.

“Total Assets” as of any date means the sum of:

•

our Undepreciated Real Estate Assets, and

•

all of our other assets determined in accordance with generally accepted accounting principles, but excluding intangibles.

“Undepreciated Real Estate Assets” as of any date means the original cost plus capital improvements of our real estate assets on the date, before depreciation and amortization determined on a consolidated basis in accordance with generally accepted accounting principles.

Except as described above, the Indentures do not contain any provisions that would limit our ability to incur indebtedness or that would afford holders of the debt securities protection in the event of a highly leveraged or similar transaction involving us or in the event of a change of control. However, our charter, contains ownership and transfer restrictions relating to our stock that are designed primarily to preserve our status as a REIT for U.S. federal income tax purposes. The Internal Revenue Code generally provides that concentration of more than 50% in value of direct or indirect ownership of our stock in five or fewer individual stockholders during the last six months of any year, or ownership of our stock by fewer than 100 persons on more than a limited number of days during any taxable year, will result in our disqualification as a REIT for such purposes. Provisions of our charter that are intended to prevent concentration of ownership may prevent or hinder a change of control. You should refer to the applicable prospectus supplement for information with respect to any deletions from, modifications of or additions to the events of default or covenants of UDR that are described in this section, including any addition of a covenant or other provision providing event risk or similar protection.

Covenants Under Both Indentures. Each Indenture includes the following covenants:

Existence. Except as described above under “Merger, Consolidation or Sale,” we will do or cause to be done all things necessary to preserve and keep in full force and effect our existence, rights, both under our charter and statutory, and franchises. However, we will not be required to preserve any right or franchise if our board of directors determines that its preservation is no longer desirable in the conduct of our business and the business of our subsidiaries as a whole and that the loss thereof is not disadvantageous in any material respect to the holders of the debt securities of any series.

Maintenance of Properties. We will cause all of our properties used or useful in the conduct of our business or the business of any subsidiary to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in our judgment may be necessary so that our business may be properly and advantageously conducted at all times. However, we will not be prevented from selling or otherwise disposing of for value our properties in the ordinary course of business.

Insurance. We will, and will cause each of our subsidiaries to, keep all of our insurable properties insured against loss or damage in an amount at least equal to their then full insurable value with financially sound and reputable insurance companies.

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

•

all taxes, assessments and governmental charges levied or imposed upon us or any subsidiary or upon our or any subsidiary’s income, profits or property, and

•

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

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

Provision of Financial Information. Whether or not we are subject to Sections 13 or 15(d) of the Exchange Act, we will, to the extent permitted under the Exchange Act, file with the SEC the annual reports, quarterly

reports and other documents that we would have been required to file with the SEC pursuant to Sections 13 and 15(d) if we were subject to those Sections. We will also in any event:

•

within 15 days of each required filing date

•

transmit by mail to all holders of debt securities, as their names and addresses appear in the security register, without cost to the holders, copies of the annual reports and quarterly reports that we would have been required to file with the SEC pursuant to Sections 13 or 15(d) of the Exchange Act if we were subject to those Sections, and

•

file with the trustee copies of the annual reports, quarterly reports and other documents that we would have been required to file with the SEC pursuant to Sections 13 or 15(d) of the Exchange Act if we were subject to those Sections, and

•

if our filing the documents with the SEC is not permitted under the Exchange Act, promptly upon written request and payment of the reasonable cost of duplication and delivery, supply copies of the documents to any prospective holder.

Events of Default, Notice and Waiver. Each Indenture provides that the following events are “events of default” with respect to any issued series of debt securities:

•

default for 30 days in the payment of any installment of interest or additional amounts payable on any debt security of the series,

•

default in the payment of the principal of, or any premium or make-whole amount 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 performance of any other covenant of UDR contained in the Indenture, other than a covenant added to the Indenture solely for the benefit of a series of debt securities issued under the Indenture other than the series, continued for 60 days after written notice as provided in the Indenture,

•

default under any bond, debenture, note, mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by us, or by any subsidiary, the repayment of which we have guaranteed or for which we are directly responsible or liable as obligor or guarantor, having an aggregate principal amount outstanding of at least $10,000,000, whether the indebtedness now exists or will later be created, which default will have resulted in the indebtedness being declared due and payable prior to the date on which it would otherwise have become due and payable, without the acceleration having been rescinded or annulled within 10 days after written notice as provided in the Indenture,

•

the entry by a court of competent jurisdiction of one or more judgments, orders or decrees against us or any subsidiary in an aggregate amount, excluding amounts covered by insurance, in excess of $10,000,000 and those judgments, orders or decrees remain undischarged, unstayed and unsatisfied in an aggregate amount, excluding amounts covered by insurance, in excess of $10,000,000 for a period of 30 consecutive days,

•

certain events of bankruptcy, insolvency or reorganization, or court appointment of a receiver, liquidator or trustee of UDR or any significant subsidiary or for all or substantially all of either of their properties, and

•

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

The term “significant subsidiary” means each significant subsidiary, as defined in Regulation S-X promulgated under the Securities Act of 1933, as amended, or the Securities Act, of UDR.

If an event of default under either Indenture with respect to debt securities of any series at the time outstanding occurs and is continuing, then in every case the trustee or the holders of not less than 25% in

principal amount of the outstanding debt securities of that series may declare the principal amount, or, if the debt securities of that series are original issue discount securities or indexed securities, the portion of the principal amount as may be specified in their terms, of, and any make-whole amount on, all of the debt securities of that series to be due and payable immediately by written notice to us, and to the trustee if given by the holders. However, at any time after the declaration of acceleration with respect to debt securities of the series, or of all debt securities then outstanding under the applicable Indenture, as the case may be, has been made, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of not less than a majority in principal amount of the outstanding debt securities of the series, or of all debt securities then outstanding under the applicable Indenture, as the case may be, may rescind and annul the declaration and its consequences if:

•

we will have deposited with the trustee all required payments of the principal of and any premium or make-whole amount and interest, and any additional amounts, on the debt securities of the series, or of all debt securities then outstanding under the applicable Indenture, as the case may be, plus certain fees, expenses, disbursements and advances of the trustee, and

•

all events of default, other than the nonpayment of accelerated principal, or specified portion thereof and any premium or make-whole amount, or interest, with respect to the debt securities of the series, or of all debt securities then outstanding under the applicable Indenture, as the case may be, have been cured or waived as provided in the Indenture.

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

•

in the payment of the principal of, or any premium or make-whole amount, or interest or additional amounts payable on any debt security of the series, or

•

in respect of a covenant or provision contained in the applicable Indenture that cannot be modified or amended without the consent of the holder of each affected outstanding debt security.

Each trustee is required to give notice to the holders of debt securities within 90 days of a default under the applicable Indenture. However, the trustee may withhold notice to the holders of any series of debt securities of any default with respect to that series, except a default in the payment of the principal of, or any premium or make-whole amount, or interest or additional amounts payable, on any debt security of the series or in the payment of any sinking fund installment in respect of any debt security of the series, if the trustee considers the withholding to be in the interest of the holders.

Each Indenture provides that no holders of debt securities of any series may institute any proceedings, judicial or otherwise, with respect to the Indenture or for any remedy thereunder, except in the case of failure of the trustee for 60 days to act after it has received a written request to institute proceedings in respect of an event of default from the holders of not less than 25% in principal amount of the outstanding debt securities of the series, as well as an offer of reasonable indemnity. This provision will not prevent, however, any holder of debt securities from instituting suit for the enforcement of payment of the principal of, and any premium or make-whole amount, interest on and additional amounts payable with respect to, the debt securities at their respective due dates.

Modification of the Indentures. We and the applicable trustee may modify and amend either Indenture with the consent of the holders of not less than a majority in principal amount of all outstanding debt securities issued under the Indenture affected by the modification or amendment. However, we must have the consent of the holders of all affected outstanding debt securities to:

•

change the stated maturity of the principal of, or any premium or make-whole amount, or any installment of principal of or interest or additional amounts payable on, any debt security,

•

reduce the principal amount of, or the rate or amount of interest on, or any premium or make-whole amount payable on redemption of, or any additional amounts payable with respect to, any debt security,

or reduce the amount of principal of an original issue discount security or make-whole amount, if any, that would be due and payable upon declaration of acceleration of its maturity or would be provable in bankruptcy, or adversely affect any right of repayment of the holder of any debt security,

•

change the place of payment, or the coin or currency, for payment of principal of, and any premium or make-whole amount, or interest on, or any additional amounts payable with respect to, a debt security,

•

impair the right to institute suit for the enforcement of any payment on or with respect to any debt security,

•

reduce the percentage of outstanding debt securities of any series necessary to modify or amend the applicable Indenture, to waive compliance with any provisions of that Indenture or any defaults and consequences thereunder or to reduce the quorum or voting requirements set forth in the Indenture, or

•

modify any of the foregoing provisions or any of the provisions relating to the waiver of certain past defaults or certain covenants, except to increase the required percentage to effect the action or to provide that certain other provisions may not be modified or waived without the consent of the holder of the debt security.

The holders of not less than a majority in principal amount of outstanding debt securities issued under either Indenture have the right to waive our compliance with some covenants in the Indenture.

Subordination. Upon any distribution to our creditors in a liquidation, dissolution, reorganization or similar proceeding, the payment of the principal of and interest on subordinated debt securities issued under the Subordinated Indenture will be subordinated to the extent provided in the Subordinated Indenture in right of payment to the prior payment in full of all senior debt. Our obligation to make payment of the principal and interest on the subordinated debt securities will not otherwise be affected.

No payment of principal or interest may be made on the subordinated debt securities at any time if a default on senior debt exists that permits the holders of the senior debt to accelerate its maturity and the default is the subject of judicial proceedings or we receive notice of the default. After all senior debt is paid in full and until the subordinated debt securities are paid in full, holders will be subrogated to the rights of holders of senior debt to the extent that distributions otherwise payable to holders have been applied to the payment of senior debt. By reason of this subordination, in the event of a distribution of assets upon insolvency, certain of our general creditors may recover more, ratably, than holders of the subordinated debt securities.

Senior debt is defined in the Subordinated Indenture as the principal of and interest on, or substantially similar payments to be made by UDR in respect of, the following, whether outstanding at the date of execution of the Subordinated Indenture or thereafter incurred, created or assumed:

•

our indebtedness for money borrowed or represented by purchase-money obligations,

•

our indebtedness evidenced by notes, debentures, or bonds, or other securities issued under the provisions of an indenture, fiscal agency agreement or other instrument,

•

our obligations as lessee under leases of property either made as part of any sale and lease-back transaction to which we are a party or otherwise,

•

indebtedness of partnerships and joint ventures that is included in our consolidated financial statements,

•

indebtedness, obligations and liabilities of others in respect of which we are liable contingently or otherwise to pay or advance money or property or as guarantor, endorser or otherwise or which we have agreed to purchase or otherwise acquire, and

•

any binding commitment of us to fund any real estate investment or to fund any investment in any entity making a real estate investment, in each case other than the following:

•

any indebtedness, obligation or liability referred to in the above bullet points as to which, in the instrument creating or evidencing the same pursuant to which the same is outstanding, it is provided that the indebtedness, obligation or liability is not superior in right of payment to the subordinated debt securities or ranks pari passu with the subordinated debt securities,

•

any indebtedness, obligation or liability that is subordinated to indebtedness of UDR to substantially the same extent as or to a greater extent than the subordinated debt securities are subordinated, and

•

the subordinated debt securities.

At June 30, 2011, our senior unsecured debt totaled approximately $1,702,148,000.

Discharge, Defeasance and Covenant Defeasance. Under each Indenture, we may discharge certain obligations to holders of any series of debt securities issued under the Indenture that have not already been delivered to the applicable 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 applicable trustee, in trust, funds in the currency or currencies, currency unit or units or composite currency or currencies in which the debt securities are payable in an amount sufficient to pay the entire indebtedness on the debt securities in respect of principal, and any premium or make-whole amount, and interest and any additional amounts payable to the date of the deposit, if the debt securities have become due and payable, or to the stated maturity or redemption date, as the case may be.

Each Indenture provides that, if the provisions of its Article Fourteen are made applicable to the debt securities of or within any series pursuant the Indenture, we may elect:

•

“defeasance,” which is to defease and be discharged from any and all obligations with respect to the debt securities, except for the obligation to pay additional amounts, if any, upon the occurrence of certain events of tax, assessment or governmental charge with respect to payments on the debt securities and the obligations to register the transfer or exchange of the debt securities, to replace temporary or mutilated, destroyed, lost or stolen debt securities, to maintain an office or agency in respect of the debt securities and to hold moneys for payment in trust, or

•

“covenant defeasance,” which is to be released from our obligations with respect to the debt securities under provisions of each Indenture described under “Covenants Under the Senior Indenture” and “Covenants Under Both Indentures” above, or, if provided pursuant to Section 301 of each Indenture, our obligations with respect to any other covenant, and any omission to comply with the obligations will not constitute a default or an event or default with respect to the debt securities issued under the Indenture.

In either case upon our irrevocable deposit with the applicable trustee, in trust, of an amount, in the currency or currencies, currency unit or currency units or composite currency or currencies in which the debt securities are payable at stated maturity, or Government Obligations (as defined below), or both, applicable to the debt securities that through the scheduled payment of principal and interest in accordance with their terms will provide money in an amount sufficient to pay the principal of, and any premium or make-whole amount, and interest on the debt securities, and any mandatory sinking fund or analogous payments thereon, on the scheduled due dates therefor.

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

“Government Obligations” means securities that are:

•

direct obligations of the United States of America or the government that issued the foreign currency in which the debt securities of a particular series are payable, for the payment of which its full faith and credit is pledged, or

•

obligations of a person controlled or supervised by and acting as an agency or instrumentality of the United States of America or the government that issued the foreign currency in which the debt securities of the series are payable, the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America or any other government, which, in either case, are not callable or redeemable at the option of the issuer, and will also include a depository receipt issued by a bank or trust company as custodian with respect to any Government Obligation or a specific payment of interest on or principal of any Government Obligation held by the custodian for the account of the holder of a depository receipt, provided that, except as required by law, the custodian is not authorized to make any deduction from the amount payable to the holder of the depository receipt from any amount received by the custodian in respect of the Government Obligation or the specific payment of interest on or principal of the Government Obligation evidenced by the depository receipt.

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

•

the holder of a debt security of the series is entitled to, and does, elect pursuant to Section 301 of the Indenture or the terms of the debt security to receive payment in a currency, currency unit or composite currency other than that in which the deposit has been made in respect of the debt security, or

•

Conversion Event (as defined below) occurs in respect of the currency, currency unit or composite currency in which the deposit has been made, the indebtedness represented by the debt security will be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of, and any premium or make-whole amount, and interest on the debt security as they become due out of the proceeds yielded by converting the amount deposited in respect of the debt security into the currency, currency unit or composite currency in which the debt security becomes payable as a result of the election or cessation of usage based on the applicable market exchange rate.

“Conversion Event” means the cessation of use of:

•

a currency, currency unit or composite currency, other than the ECU or other currency unit, both by the government of the country that issued the currency and for the settlement of transactions by a central bank or other public institutions of or within the international banking community,

•

the ECU both within the European Monetary System and for the settlement of transactions by public institutions of or within the European Communities, or

•

any currency unit or composite currency other than the ECU for the purposes for which it was established.

Unless otherwise provided in the prospectus supplement, all payments of principal of, and any premium or make-whole amount, and interest on any debt security issued under an Indenture that is payable in a foreign currency that ceases to be used by its government of issuance will be made in United States dollars.

If we effect covenant defeasance with respect to any debt securities and those debt securities are declared due and payable because of the occurrence of any event of default, the amount in the currency, currency unit or composite currency in which the debt securities are payable, and Government Obligations on deposit with the trustee, will be sufficient to pay amounts due on the debt securities at the time of their stated maturity but may

not be sufficient to pay amounts due on the debt securities at the time of the acceleration resulting from the event of default. This situation will not apply in the case of an event of default described in the fourth bullet point under “Events of Default, Notice and Waiver” of either Indenture, which sections would no longer be applicable to the debt securities or described in the last bullet point under “Events of Default, Notice and Waiver” with respect to a covenant as to which there has been covenant defeasance. However, we would remain liable to make payment of the amounts due at the time of acceleration.

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

Book-Entry System. We may issue debt securities of a series as one or more fully registered global securities. We will deposit the global securities with, or on behalf of, a depository bank identified in the prospectus supplement relating to the series. We will register the global securities in the name of the depository bank or its nominee. In that case, one or more global securities will be issued in a denomination or aggregate denominations equal to the aggregate principal amount of outstanding debt securities of the series represented by the global security or securities. Until any global security is exchanged in whole or in part for debt securities in definitive certificated form, the depository bank or its nominee may not transfer the global certificate except to each other, another nominee or to their successors and except as described in the applicable prospectus supplement.

The prospectus supplement will describe the specific terms of the depository arrangement with respect to a series of debt securities that a global security will represent. We anticipate that the following provisions will apply to all depository arrangements.

Upon the issuance of any global security, and the deposit of the global security with or on behalf of the depository bank for the global security, the depository bank will credit, on its book-entry registration and transfer system, the respective principal amounts of the debt securities represented by the global security to the accounts of institutions, also referred to as “participants,” that have accounts with the depository bank or its nominee. The accounts to be credited will be designated by the underwriters or agents engaging in the distribution or placement of the debt securities or by us, if we offer and sell the debt securities directly. Ownership of beneficial interests in the global security will be limited to participants or persons that may hold interests through participants.

Ownership of beneficial interests by participants in the global security will be shown by book-keeping entries on, and the transfer of that ownership interest will be effected only through book-keeping entries to, records maintained by the depository bank or its nominee for the global security. Ownership of beneficial interests in the global security by persons that hold through participants will be shown by book-keeping entries on, and the transfer of that ownership interest among or through the participants will be effected only through book-keeping entries to, records maintained by the participants.

The laws of some jurisdictions require that some of the purchasers of securities take physical delivery of the securities in definitive certificated form rather than book-entry form. Such laws may impair the ability to own, transfer or pledge beneficial interests in any global security.

So long as the depository bank for a global security or its nominee is the registered owner of the global security, the depository bank or the nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the global security for all purposes under the Indenture. Except as described below or otherwise specified in the applicable prospectus supplement, owners of beneficial interests in a global security:

•

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

•

will not receive or be entitled to receive physical delivery of debt securities of the series in definitive certificated form, and

•

will not be considered the holders thereof for any purposes under the applicable indenture.

Accordingly, each person owning a beneficial interest in the global security must rely on the procedures of the depository bank and, if the person is not a participant, on the procedures of the participant through which the person directly or indirectly owns its interest, to exercise any rights of a holder under the applicable indenture. The depository bank may grant proxies and otherwise authorize participants to give or take any request, demand, authorization, direction, notice, consent, waiver or other action that a holder is entitled to give or take under the indenture.

We understand that under existing industry practices, if we request any action of holders or any owner of a beneficial interest in the global security desires to give any notice or take any action that a holder is entitled to give or take under the indenture, the depository bank for the global security would authorize the participants holding the relevant beneficial interest to give notice or take action, and the participants would authorize beneficial owners owning through the participants to give notice or take action or would otherwise act upon the instructions of beneficial owners owning through them.

Principal and any premium and interest payments on debt securities represented by a global security registered in the name of a depository bank or its nominee will be made to the depository bank or its nominee, as the case may be, as the registered owner of the global security. None of us, the trustee or any paying agent for the debt securities will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in any global security or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests.

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

If the depository bank for any series of debt securities represented by a global security is at any time unwilling or unable to continue as depository bank and we do not appoint a successor depository bank within 90 days, we will issue the debt securities in definitive certificated form in exchange for the global security. In addition, we may at any time and in our sole discretion determine not to have the debt securities of a series represented by one or more global securities and, in that event, will issue debt securities of the series in definitive certificated form in exchange for the global security representing the series of debt securities.

Debt securities of the series issued in definitive certificated form will, except as described in the applicable prospectus supplement, be issued in denominations of $1,000 and integral multiples thereof and will be issued in registered form.

Trustees. U.S. Bank National Association (successor trustee to Wachovia Bank, National Association, formerly known as First Union National Bank of Virginia) is the trustee under the Senior Indenture and is the trustee (as successor trustee to SunTrust Bank, formerly known as Crestar Bank) under the Subordinated Indenture. Both U.S. Bank and SunTrust Bank have lending relationships with us.

DESCRIPTION OF GUARANTEES OF THE DEBT SECURITIES

If specified in the applicable prospectus supplement, certain of our subsidiaries, including the Operating Partnership, will guarantee the debt securities. The particular terms of any guarantee will be described in the related prospectus supplement.

We may issue warrants for the purchase of common stock, preferred stock or debt securities. We may issue warrants independently or together with any offered securities. The warrants may be attached to or separate from those offered securities. We will issue the warrants under one or more warrant agreements to be entered into

between us and a warrant agent to be named in the applicable prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.

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

•

the title of the warrants;

•

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

•

the designation, amount and terms of the securities for which the warrants are exercisable;

•

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

•

the aggregate number of warrants;

•

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

•

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

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

Exercise of Warrants

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

The description in the applicable prospectus supplement of any warrants we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable warrant agreement and warrant certificate, which will be filed with the SEC if we offer warrants. For more information on how you can obtain copies of any warrant certificate or warrant agreement if we offer warrants, see “Where You Can Find More Information” beginning on page 52 of this prospectus. We urge you to read the applicable warrant certificate, the applicable warrant agreement and any applicable prospectus supplement in their entirety.

DESCRIPTION OF SUBSCRIPTION RIGHTS

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

For more information on how you can obtain copies of any subscription rights certificate or subscription rights agreement if we offer subscription rights, see “Where You Can Find More Information” beginning on page 52 of this prospectus. We urge you to read the applicable subscription rights certificate, the applicable subscription rights agreement and any applicable prospectus supplement in their entirety.

DESCRIPTION OF PURCHASE CONTRACTS AND PURCHASE UNITS

We may issue purchase contracts for the purchase or sale of common stock, preferred stock or debt securities issued by us or by third parties as specified in the applicable prospectus supplement. Each purchase contract will entitle the holder thereof to purchase or sell, and obligate us to sell or purchase on specified dates, such securities at a specified purchase price, which may be based on a formula, all as set forth in the applicable prospectus supplement. We may, however, satisfy our obligations, if any, with respect to any purchase contract by delivering the cash value of such purchase contract or the cash value of the securities otherwise deliverable, as set forth in the applicable prospectus supplement. The applicable prospectus supplement will also specify the methods by which the holders may purchase or sell such securities, and any acceleration, cancellation or termination provisions or other provisions relating to the settlement of a purchase contract. The price per security and the number of securities may be fixed at the time the purchase contracts are entered into or may be determined by reference to a specific formula set forth in the applicable purchase contracts.

The purchase contracts may be issued separately or as part of units consisting of a purchase contract and debt securities or debt obligations of third parties, including U.S. treasury securities, or any other securities described in the applicable prospectus supplement or any combination of the foregoing, securing the holders’ obligations to purchase the securities under the purchase contracts, which we refer to herein as “purchase units.” The purchase contracts may require holders to secure their obligations under the purchase contracts in a specified manner. The purchase contracts also may require us to make periodic payments to the holders of the purchase contracts or the purchase units, as the case may be, or vice versa, and those payments may be unsecured or pre-funded on some basis.

The prospectus supplement relating to any purchase contracts or purchase units we may offer will contain the specific terms of the purchase contracts or purchase units. These terms may include the following:

•

whether the purchase contracts obligate the holder to purchase or sell, or both, our common stock, preferred stock, or debt securities, and the nature and amount of each of those securities, or method of determining those amounts;

•

whether the purchase contracts are to be prepaid or not;

•

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

•

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

•

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

The description in the applicable prospectus supplement of any purchase contract or purchase unit we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable purchase contract or purchase unit, which will be filed with the SEC if we offer purchase contracts or purchase units. For more information on how you can obtain copies of any purchase contract or purchase unit we may offer, see “Where You Can Find More Information” beginning on page 52 of this prospectus. We urge you to read the applicable purchase contract or applicable purchase unit and any applicable prospectus supplement in their entirety.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of the material U.S. federal income tax consequences of an investment in common stock of UDR, Inc. For purposes of this section under the heading “U.S. Federal Income Tax Considerations,” references to “UDR,” “we,” “our” and “us” mean only UDR, Inc. and not its subsidiaries or other lower-tier entities, except as otherwise indicated. This summary is based upon the Internal Revenue Code, the regulations promulgated by the U.S. Treasury Department, rulings and other administrative pronouncements issued by the IRS, and judicial decisions, all as currently in effect, and all of which are subject to differing interpretations or to change, possibly with retroactive effect. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax consequences described below. We have not sought and will not seek an advance ruling from the IRS regarding any matter discussed in this prospectus. The summary is also based upon the assumption that we will operate UDR and its subsidiaries and affiliated entities in accordance with their applicable organizational documents or partnership agreements. This summary is for general information only and is not tax advice. It does not purport to discuss all aspects of U.S. federal income taxation that may be important to a particular investor in light of its investment or tax circumstances or to investors subject to special tax rules, such as:

•

financial institutions;

•

insurance companies;

•

broker-dealers;

•

regulated investment companies;

•

partnerships and trusts;

•

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

•

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

•

persons holding UDR stock as part of a “straddle,” “hedge,” “conversion transaction,” “synthetic security” or other integrated investment;

and, except to the extent discussed below:

•

tax-exempt organizations; and

•

foreign investors.

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

The U.S. federal income tax treatment of holders of our common stock depends in some instances on determinations of fact and interpretations of complex provisions of U.S. federal income tax law for which no clear precedent or authority may be available. In addition, the tax consequences to any particular stockholder of holding our common stock will depend on the stockholder’s particular tax circumstances. You are urged to consult your tax advisor regarding the federal, state, local, and foreign income and other tax consequences to you in light of your particular investment or tax circumstances of acquiring, holding, exchanging, or otherwise disposing of our common stock.

Taxation of UDR

We elected to be taxed as a REIT under the U.S. federal income tax laws commencing with our taxable year ended December 31, 1972. We believe that we have been organized and operated in such a manner as to qualify for taxation as a REIT.

The law firm of Morrison & Foerster LLP has acted as our tax counsel in connection with the registration statement of which this prospectus is a part. In connection with the filing of this prospectus, we expect to receive an opinion of Kutak Rock LLP to the effect that commencing with UDR’s taxable year ending on December 31,

2007, we have been organized in conformity with the requirements for qualification and taxation as a REIT under the Internal Revenue Code, and that our actual and proposed method of operation will enable us to continue to meet the requirements for qualification and taxation as a REIT. It must be emphasized that the opinion of Kutak Rock LLP will be based on various assumptions relating to our organization and operation and will be conditioned upon fact-based representations and covenants made by our management regarding our organization, assets, and income, and the future conduct of our business operations. While we intend to operate so that we will qualify as a REIT, given the highly complex nature of the rules governing REITs, the ongoing importance of factual determinations, and the possibility of future changes in our circumstances, no assurance can be given by Kutak Rock LLP or by us that we will qualify as a REIT for any particular year. We have asked Kutak Rock LLP to assume for purposes of its opinion that any prior legal opinions we received to the effect that we were taxable as a REIT are correct and the conclusions reached in the opinion of Kutak Rock LLP are expressly conditioned on the accuracy of such assumption. The opinion will be expressed as of the date issued. Kutak Rock LLP will have no obligation to advise us or our stockholders of any subsequent change in the matters stated, represented or assumed, or of any subsequent change in the applicable law. You should be aware that opinions of counsel are not binding on the IRS, and no assurance can be given that the IRS will not challenge the conclusions set forth in such opinions.

Qualification and taxation as a REIT depends on our ability to meet on a continuing basis, through actual operating results, distribution levels, and diversity of stock and asset ownership, various qualification requirements imposed upon REITs by the Internal Revenue Code, the compliance with which will not be reviewed by Morrison & Foerster LLP. Our ability to qualify as a REIT also requires that we satisfy certain asset tests, some of which depend upon the fair market values of assets that we own directly or indirectly. Such values may not be susceptible to a precise determination. Accordingly, no assurance can be given that the actual results of our operations for any taxable year will satisfy such requirements for qualification and taxation as a REIT.

Taxation of REITs in General

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

Provided that we qualify as a REIT, generally we will be entitled to a deduction for dividends that we pay and therefore will not be subject to U.S. federal corporate income tax on our taxable income that is currently distributed to our stockholders. This treatment substantially eliminates the “double taxation” at the corporate and stockholder levels that generally results from investment in a corporation. In general, the income that we generate is taxed only at the stockholder level upon a distribution of dividends to our stockholders.

For tax years through 2012, most domestic stockholders that are individuals, trusts or estates are taxed on corporate dividends at a maximum rate of 15% (the same as long-term capital gains). With limited exceptions, however, dividends from us or from other entities that are taxed as REITs are generally not eligible for this rate and will continue to be taxed at rates applicable to ordinary income, which will be as high as 35% through 2012. See “Taxation of Stockholders—Taxation of Taxable Domestic Stockholders—Distributions.”

Net operating losses, foreign tax credits and other tax attributes generally do not pass through to our stockholders. See “Taxation of Stockholders.”

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

•

We will be taxed at regular corporate rates on any undistributed “real estate investment trust taxable income,” including undistributed net capital gains.

•

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

•

If we have net income from prohibited transactions, which are, in general, sales or other dispositions of inventory or property held primarily for sale to customers in the ordinary course of business, other than foreclosure property, such income will be subject to a 100% tax. See “—Prohibited Transactions,” and “—Foreclosure Property,” below.

•

If we elect to treat property that we acquire in connection with a foreclosure of a mortgage loan or certain leasehold terminations as “foreclosure property,” we may thereby avoid the 100% tax on gain from a resale of that property (if the sale would otherwise constitute a prohibited transaction), but the income from the sale or operation of the property may be subject to corporate income tax at the highest applicable rate (currently 35%).

•

If we should fail to satisfy the 75% gross income test or the 95% gross income test, as discussed below, but nonetheless maintain our qualification as a REIT because we satisfy other requirements, we will be subject to a 100% tax on an amount based on the magnitude of the failure, as adjusted to reflect the profit margin associated with our gross income.

•

If we should violate the asset tests (other than certain de minimis violations) or other requirements applicable to REITs, as described below, and yet maintain our qualification as a REIT because there is reasonable cause for the failure and other applicable requirements are met, we may be subject to an excise tax. In that case, the amount of the excise tax will be at least $50,000 per failure, and, in the case of certain asset test failures, will be determined as the amount of net income generated by the assets in question multiplied by the highest corporate tax rate (currently 35%) if that amount exceeds $50,000 per failure.

•

If we should fail to distribute during each calendar year at least the sum of (a) 85% of our REIT ordinary income for such year, (b) 95% of our REIT capital gain net income for such year, and (c) any undistributed taxable income from prior periods, we would be subject to a nondeductible 4% excise tax on the excess of the required distribution over the sum of (i) the amounts that we actually distributed and (ii) the amounts we retained and upon which we paid income tax at the corporate level.

•

We may be required to pay monetary penalties to the IRS in certain circumstances, including if we fail to meet record keeping requirements intended to monitor our compliance with rules relating to the composition of a REIT’s stockholders, as described below in “—Requirements for Qualification—General.”

•

A 100% tax may be imposed on transactions between us and a “taxable REIT subsidiary” (“TRS”) (as described below) that do not reflect arms-length terms.

•

If we acquire appreciated assets from a corporation that is not a REIT (i.e., a corporation taxable under subchapter C of the Internal Revenue Code) in a transaction in which the adjusted tax basis of the assets in our hands is determined by reference to the adjusted tax basis of the assets in the hands of the subchapter C corporation, we may be subject to tax on such appreciation at the highest corporate income tax rate then applicable if we subsequently recognize gain on a disposition of any such assets during the ten-year period following their acquisition from the subchapter C corporation.

•

The earnings of our subsidiaries, including any TRS, are subject to federal corporate income tax to the extent that such subsidiaries are subchapter C corporations.

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

Requirements for Qualification—General

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

(1)

that is managed by one or more trustees or directors;

(2)

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

(3)

that would be taxable as a domestic corporation but for its election to be subject to tax as a REIT;

(4)

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

(5)

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

(6)

in which, during the last half of each taxable year, not more than 50% in value of the outstanding stock is owned, directly or indirectly, by five or fewer “individuals” (as defined in the Internal Revenue Code to include specified tax-exempt entities); and

(7)

which meets other tests described below, including with respect to the nature of its income and assets.

The Internal Revenue Code provides that conditions (1) through (4) must be met during the entire taxable year, and that condition (5) must be met during at least 335 days of a taxable year of 12 months, or during a proportionate part of a shorter taxable year. Conditions (5) and (6) need not be met during a corporation’s initial tax year as a REIT. Our charter provides restrictions regarding the ownership and transfers of our shares, which are intended to assist us in satisfying the share ownership requirements described in conditions (5) and (6) above.

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

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

The Internal Revenue Code provides relief from violations of certain of the REIT requirements, in cases where a violation is due to reasonable cause and not to willful neglect, and other requirements are met, including, in certain cases, the payment of a penalty tax that is based upon the magnitude of the violation. See “—Income Tests” and “—Asset Tests” below. If we fail to satisfy any of the various REIT requirements, there can be no assurance that these relief provisions would be available to enable us to maintain our qualification as a REIT, and, if such relief provisions are available, the amount of any resultant penalty tax could be substantial.

Effect of Subsidiary Entities

Ownership of Partnership Interests. If we are a partner in an entity that is treated as a partnership for U.S. federal income tax purposes, Treasury regulations provide that we are deemed to own our proportionate share of the partnership’s assets, and to earn our proportionate share of the partnership’s income, for purposes of the asset and gross income tests applicable to REITs. Our proportionate share of a partnership’s assets and

income is based on our capital interest in the partnership (except that for purposes of the 10% value test, our proportionate share of the partnership’s assets is based on our proportionate interest in the equity and certain debt securities issued by the partnership). In addition, the assets and gross income of the partnership are deemed to retain the same character in our hands. Thus, our proportionate share of the assets and items of income of any of our subsidiary partnerships will be treated as our assets and items of income for purposes of applying the REIT requirements. A summary of certain rules governing the federal income taxation of partnerships and their partners is provided below in “Tax Aspects of Investments in Affiliated Partnerships.”

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

In the event that a disregarded subsidiary of ours ceases to be wholly-owned—for example, if any equity interest in the subsidiary is acquired by a person other than us or another disregarded subsidiary of ours—the subsidiary’s separate existence would no longer be disregarded for U.S. federal income tax purposes. Instead, the subsidiary would have multiple owners and would be treated as either a partnership or a taxable corporation. Such an event could, depending on the circumstances, adversely affect our ability to satisfy the various asset and gross income requirements applicable to REITs, including the requirement that REITs generally may not own, directly or indirectly, more than 10% of the securities of another corporation. See “—Asset Tests” and “—Income Tests.”

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

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

Income Tests

In order to qualify as a REIT, we must satisfy two gross income requirements on an annual basis. First, at least 75% of our gross income for each taxable year, excluding gross income from sales of inventory or dealer property in “prohibited transactions” and certain hedging transactions, generally must be derived from investments relating to real property or mortgages on real property, including interest income derived from mortgage loans secured by real property (including certain types of mortgage backed securities), “rents from real property,” dividends received from other REITs, and gains from the sale of real estate assets, as well as specified

income from temporary investments. Second, at least 95% of our gross income in each taxable year, excluding gross income from prohibited transactions and certain hedging transactions, must be derived from some combination of such income from investments in real property (i.e., income that qualifies under the 75% income test described above), as well as other dividends, interest, and gain from the sale or disposition of stock or securities, which need not have any relation to real property.

Rents we receive from a tenant will qualify as “rents from real property” for the purpose of satisfying the gross income requirements for a REIT described above only if all of the following conditions are met:

•

The amount of rent must not be based in any way on the income or profits of any person. However, an amount we receive or accrue generally will not be excluded from the term “rents from real property” solely because it is based on a fixed percentage or percentages of receipts or sales;

•

We, or an actual or constructive owner of 10% or more of our stock, must not actually or constructively own 10% or more of the interests in the assets or net profits of the tenant, or, if the tenant is a corporation, 10% or more of the voting power or value of all classes of stock of the tenant;

•

Rent attributable to personal property, leased in connection with a lease of real property, is not greater than 15% of the total rent received under the lease. If this condition is not met, then the portion of the rent attributable to personal property will not qualify as “rents from real property”; and

•

We generally must not operate or manage the property or furnish or render services to our tenants, subject to a 1% de minimis exception and except as provided below. We may, however, perform services that are “usually or customarily rendered” in connection with the rental of space for occupancy only and are not otherwise considered “rendered to the occupant” of the property. Examples of these services include the provision of light, heat, or other utilities, trash removal and general maintenance of common areas. In addition, we may employ an independent contractor from whom we derive no income to provide customary services, or a taxable REIT subsidiary, which may be wholly or partially owned by us, to provide both customary and non-customary services to our tenants without causing the rent we receive from those tenants to fail to qualify as “rents from real property.” Any amounts we receive from a taxable REIT subsidiary with respect to the taxable REIT subsidiary’s provision of non-customary services will, however, be nonqualifying income under the 75% gross income test and, except to the extent received through the payment of dividends, the 95% REIT gross income test.

We generally do not intend, and as the general partner of certain subsidiary partnerships do not intend to permit our subsidiary partnerships, to take actions we believe will cause us to fail to satisfy the rental conditions described above. In addition, with respect to the limitation on the rental of personal property, we have not obtained appraisals of the real property and personal property leased to tenants. Accordingly, there can be no assurance that the IRS will agree with our determinations of value.

Income we receive that is attributable to the rental of parking spaces at the properties will constitute rents from real property for purposes of the REIT gross income tests if certain services provided with respect to the parking facilities are performed by independent contractors from whom we derive no income, either directly or indirectly, or by a taxable REIT subsidiary, and certain other conditions are met. We believe that the income we receive that is attributable to parking facilities meets these tests and, accordingly, will constitute rents from real property for purposes of the REIT gross income tests.

From time to time, we may enter into hedging transactions with respect to one or more of our liabilities. The term “hedging transaction” generally means any transaction we enter into in the normal course of our business primarily to manage risk of interest rate changes or fluctuations with respect to borrowings made or to be made. The hedging activities may include entering into interest rate swaps, caps, and floors, options to purchase these items, and futures and forward contracts. Income from a hedging transaction, including gain from the sale or disposition of such a transaction, that is clearly identified as such as specified in the Internal Revenue Code will

not constitute gross income for purposes of the 75% or 95% gross income test (for transactions entered into prior to July 31, 2008, hedging transaction income will not constitute gross income for purposes of the 95% gross income test only), and therefore will be exempt from this test. To the extent that we do not properly identify such transactions as hedges, the income from those transactions is not likely to be treated as qualifying income for purposes of the gross income tests. We intend to structure any hedging transactions in a manner that does not jeopardize our status as a REIT.

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

Interest income constitutes qualifying mortgage interest for purposes of the 75% gross income test to the extent that the obligation upon which such interest is paid is secured by a mortgage on real property. If we receive interest income with respect to a mortgage loan that is secured by both real property and other property, and the highest principal amount of the loan outstanding during a taxable year exceeds the fair market value of the real property on the date that we acquired or originated the mortgage loan, the interest income will be apportioned between the real property and the other collateral, and our income from the arrangement will qualify for purposes of the 75% gross income test only to the extent that the interest is allocable to the real property. Even if a loan is not secured by real property, or is undersecured, the income that it generates may nonetheless qualify for purposes of the 95% gross income test.

If we fail to satisfy one or both of the 75% or 95% gross income tests for any taxable year, we may still qualify as a REIT for such year if we are entitled to relief under applicable provisions of the Internal Revenue Code. These relief provisions will be generally available if (1) our failure to meet these tests was due to reasonable cause and not due to willful neglect and (2) following our identification of the failure to meet the 75% or 95% gross income test for any taxable year, we file a schedule with the IRS setting forth each item of our gross income for purposes of the 75% or 95% gross income test for such taxable year in accordance with Treasury regulations yet to be issued. It is not possible to state whether we would be entitled to the benefit of these relief provisions in all circumstances. If these relief provisions are inapplicable to a particular set of circumstances, we will not qualify as a REIT. As discussed above under “—Taxation of REITs in General,” even where these relief provisions apply, the Internal Revenue Code imposes a tax based upon the amount by which we fail to satisfy the particular income test.

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

Asset Tests

At the close of each calendar quarter, we must also satisfy four tests relating to the nature of our assets. First, at least 75% of the value of our total assets must be represented by some combination of “real estate assets,” cash, cash items, U.S. government securities, and, under some circumstances, stock or debt instruments purchased with new capital. For this purpose, real estate assets include interests in real property, such as land, buildings, leasehold interests in real property, stock of other corporations that qualify as REITs, and some kinds of mortgage-backed securities and mortgage loans. Assets that do not qualify for purposes of the 75% gross test are subject to the additional asset tests described below.

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

Third, we may not own more than 10% of any one issuer’s outstanding securities, as measured by either voting power or value. The 5% and 10% asset tests do not apply to securities of TRSs and qualified REIT

subsidiaries and the 10% asset test does not apply to “straight debt” having specified characteristics and to certain other securities described below. Solely for purposes of the 10% asset test, the determination of our interest in the assets of a partnership or limited liability company in which we own an interest will be based on our proportionate interest in any securities issued by the partnership or limited liability company, excluding for this purpose certain securities described in the Internal Revenue Code.

Fourth, the aggregate value of all securities of TRSs that we hold may not exceed 25% (20% with respect to taxable years commencing prior to July 31, 2008) of the value of our total assets.

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

Certain securities will not cause a violation of the 10% asset test described above. Such securities include instruments that constitute “straight debt,” which includes, among other things, securities having certain contingency features. A security does not qualify as “straight debt” where a REIT (or a controlled TRS of the REIT) owns other securities of the same issuer which do not qualify as straight debt, unless the value of those other securities constitute, in the aggregate, 1% or less of the total value of that issuer’s outstanding securities. In addition to straight debt, the Internal Revenue Code provides that certain other securities will not violate the 10% asset test. Such securities include (1) any loan made to an individual or an estate, (2) certain rental agreements pursuant to which one or more payments are to be made in subsequent years (other than agreements between a REIT and certain persons related to the REIT under attribution rules), (3) any obligation to pay rents from real property, (4) securities issued by governmental entities that are not dependent in whole or in part on the profits of (or payments made by) a non-governmental entity, (5) any security (including debt securities) issued by another REIT, and (6) any debt instrument issued by a partnership if the partnership’s income is of a nature that it would satisfy the 75% gross income test described above under “—Income Tests.” In applying the 10% asset test, a debt security issued by a partnership is not taken into account to the extent, if any, of the REIT’s proportionate interest in the equity and certain debt securities issued by that partnership.

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

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

In the case of de minimis violations of the 10% and 5% asset tests, a REIT may maintain its qualification despite a violation of such requirements if (1) the value of the assets causing the violation does not exceed the lesser of 1% of the REIT’s total assets and $10,000,000, and (2) the REIT either disposes of the assets causing

the failure within six months after the last day of the quarter in which it identifies the failure, or the relevant tests are otherwise satisfied within that time frame.

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

Annual Distribution Requirements

In order to qualify as a REIT, we are required to distribute dividends, other than capital gain dividends, to our stockholders in an amount at least equal to:

(a)

the sum of

(1)

90% of our “REIT taxable income,” computed without regard to our net capital gains and the deduction for dividends paid, and

(2)

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

(b)

the sum of specified items of non-cash income.

We generally must make these distributions in the taxable year to which they relate, or in the following taxable year if declared before we timely file our tax return for the year and if paid with or before the first regular dividend payment after such declaration. In order for distributions to be counted as satisfying the annual distribution requirements for REITS, and to provide us with a REIT-level tax deduction, the distributions must not be “preferential dividends.” A dividend is not a preferential dividend if the distribution is (1) pro rata among all outstanding shares of stock within a particular class, and (2) in accordance with the preferences among different classes of stock as set forth in our organizational documents.

To the extent that we distribute at least 90%, but less than 100%, of our “REIT taxable income,” as adjusted, we will be subject to tax at regular corporate tax rates on the retained portion. We may elect to retain, rather than distribute, our net long-term capital gains and pay tax on such gains. In this case, we could elect for our stockholders to include their proportionate shares of such undistributed long-term capital gains in income, and to receive a corresponding credit for their share of the tax that we paid. Our stockholders would then increase their adjusted basis of their stock by the difference between (a) the amounts of capital gain dividends that we designated and that they include in their taxable income, and (b) the tax that we paid on their behalf with respect to that income.

To the extent that in the future we may have available net operating losses carried forward from prior tax years, such losses may reduce the amount of distributions that we must make in order to comply with the REIT distribution requirements. Such losses, however, will generally not affect the character, in the hands of our stockholders, of any distributions that are actually made as ordinary dividends or capital gains. See “—Taxation of Stockholders—Taxation of Taxable Domestic Stockholders—Distributions.”

If we should fail to distribute during each calendar year at least the sum of (a) 85% of our REIT ordinary income for such year, (b) 95% of our REIT capital gain net income for such year, and (c) any undistributed taxable income from prior periods, we would be subject to a non-deductible 4% excise tax on the excess of such required distribution over the sum of (x) the amounts actually distributed, and (y) the amounts of income we retained and on which we paid corporate income tax.

It is possible that, from time to time, we may not have sufficient cash to meet the distribution requirements due to timing differences between our actual receipt of cash, including receipt of distributions from our subsidiaries and our inclusion of items in income for U.S. federal income tax purposes. Alternatively, we may

declare a taxable dividend payable in cash or stock at the election of each shareholder, where the aggregate amount of cash to be distributed in such dividend may be subject to limitation. In such case, for federal income tax purposes, the amount of the dividend paid in stock will be equal to the amount of cash that could have been received instead of stock.

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

We may be able to rectify a failure to meet the distribution requirements for a year by paying “deficiency dividends” to stockholders in a later year, which may be included in our deduction for dividends paid for the earlier year. In this case, we may be able to avoid losing REIT qualification or being taxed on amounts distributed as deficiency dividends. We will be required to pay interest and a penalty based on the amount of any deduction taken for deficiency dividends.

Prohibited Transactions

Net income that we derive from a prohibited transaction, is subject to a 100% tax. The term “prohibited transaction” generally includes a sale or other disposition of property (other than foreclosure property, as discussed below) that is held primarily for sale to customers in the ordinary course of a trade or business by us or by a borrower that has issued a shared appreciation mortgage or similar debt instrument to us. We intend to conduct our operations so that no asset that we own (or are treated as owning) will be treated as, or as having been, held for sale to customers, and that a sale of any such asset will not be treated as having been in the ordinary course of our business. Whether property is held “primarily for sale to customers in the ordinary course of a trade or business” depends on the particular facts and circumstances. No assurance can be given that any property that we sell will not be treated as property held for sale to customers, or that we can comply with certain safe-harbor provisions of the Internal Revenue Code that would prevent such treatment. The 100% tax does not apply to gains from the sale of property that is held through a TRS or other taxable corporation, although such income will be subject to tax in the hands of the corporation at regular corporate rates.

Foreclosure Property

Foreclosure property is real property and any personal property incident to such real property (1) that we acquire as the result of having bid in the property at foreclosure, or having otherwise reduced the property to ownership or possession by agreement or process of law, after a default (or upon imminent default) on a lease of the property or a mortgage loan held by us and secured by the property, (2) for which we acquired the related loan or lease at a time when default was not imminent or anticipated, and (3) with respect to which we made a proper election to treat the property as foreclosure property.

We generally will be subject to tax at the maximum corporate rate (currently 35%) on any net income from foreclosure property, including any gain from the disposition of the foreclosure property, other than income that constitutes qualifying income for purposes of the 75% gross income test. Any gain from the sale of property for which a foreclosure property election has been made will not be subject to the 100% tax on gains from prohibited transactions described above, even if the property would otherwise constitute inventory or dealer property. To the extent that we receive any income from foreclosure property that does not qualify for purposes of the 75% gross income test, we intend to make an election to treat the related property as foreclosure property.

Derivatives and Hedging Transactions

We and our subsidiaries may enter into hedging transactions with respect to interest rate exposure on one or more of our assets or liabilities. Any such hedging transactions could take a variety of forms, including the use of derivative instruments such as interest rate swap contracts, interest rate cap or floor contracts, futures or forward

contracts, and options. Except to the extent provided by Treasury regulations, any income from a hedging transaction we enter into (1) in the normal course of our business primarily to manage risk of interest rate or price changes or currency fluctuations with respect to borrowings made or to be made, or ordinary obligations incurred or to be incurred, to acquire or carry real estate assets, which is clearly identified as specified in Treasury regulations before the close of the day on which it was acquired, originated, or entered into, including gain from the sale or disposition of such a transaction, and (2) primarily to manage risk of currency fluctuations with respect to any item of income or gain that would be qualifying income under the 75% or 95% income tests which is clearly identified as such before the close of the day on which it was acquired, originated, or entered into, will not constitute gross income for purposes of the 75% or 95% gross income test (for transactions entered into prior to July 31, 2008, hedging transaction income will not constitute gross income for purposes of the 95% gross income test only). To the extent that we enter into other types of hedging transactions, the income from those transactions is likely to be treated as non-qualifying income for purposes of both of the 75% and 95% gross income tests. We intend to structure any hedging transactions in a manner that does not jeopardize our qualification as a REIT. We may conduct some or all of our hedging activities (including hedging activities relating to currency risk) through a TRS or other corporate entity, the income from which may be subject to federal income tax, rather than by participating in the arrangements directly or through pass-through subsidiaries. No assurance can be given, however, that our hedging activities will not give rise to income that does not qualify for purposes of either or both of the REIT income tests, or that our hedging activities will not adversely affect our ability to satisfy the REIT qualification requirements.

Failure to Qualify

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

If we fail to qualify for taxation as a REIT in any taxable year, and the relief provisions described above do not apply, we would be subject to tax, including any applicable alternative minimum tax, on our taxable income at regular corporate rates. We cannot deduct distributions to stockholders in any year in which we are not a REIT, nor would we be required to make distributions in such a year. In this situation, to the extent of current and accumulated earnings and profits, distributions to domestic stockholders that are individuals, trusts and estates will generally be taxable at capital gains rates (through 2012). In addition, subject to the limitations of the Internal Revenue Code, corporate distributees may be eligible for the dividends-received deduction. Unless we are entitled to relief under specific statutory provisions, we would also be disqualified from re-electing to be taxed as a REIT for the four taxable years following the year during which we lost qualification. It is not possible to state whether, in all circumstances, we would be entitled to this statutory relief.

Tax Aspects of Investments in Partnerships

General

We may hold investments through entities that are classified as partnerships for U.S. federal income tax purposes. In general, partnerships are “pass-through” entities that are not subject to U.S. federal income tax. Rather, partners are allocated their proportionate shares of the items of income, gain, loss, deduction and credit of a partnership, and potentially are subject to tax on these items, without regard to whether the partners receive a distribution from the partnership. We will include in our income our proportionate share of these partnership items for purposes of the various REIT income tests and in computation of our REIT taxable income. Moreover, for purposes of the REIT asset tests, we will include in our calculations our proportionate share of any assets held by subsidiary partnerships. Our proportionate share of a partnership’s assets and income is based on our capital interest in the partnership (except that for purposes of the 10% value test, our proportionate share is based on our proportionate interest in the equity and certain debt securities issued by the partnership). See “Taxation of UDR—Effect of Subsidiary Entities—Ownership of Partnership Interests.”

Entity Classification

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

Tax Allocations with Respect to Partnership Properties

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

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

Taxation of Stockholders

Taxation of Taxable Domestic Stockholders

Distributions. So long as we qualify as a REIT, the distributions that we make to our taxable domestic stockholders out of current or accumulated earnings and profits that we do not designate as capital gain dividends will generally be taken into account by stockholders as ordinary income and will not be eligible for the dividends-received deduction for corporations. With limited exceptions, our dividends are not eligible for taxation at the preferential income tax rates (i.e., the 15% maximum federal rate through the end of 2012) for

qualified dividends received by domestic stockholders that are individuals, trusts and estates from taxable C corporations. Such stockholders, however, are taxed at the preferential rates on dividends designated by and received from REITs to the extent that the dividends are attributable to:

•

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

•

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

•

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

Distributions that we designate as capital gain dividends will generally be taxed to our stockholders as long-term capital gains, to the extent that such distributions do not exceed our actual net capital gain for the taxable year, without regard to the period for which the stockholder that receives such distribution has held its stock. We may elect to retain and pay taxes on some or all of our net long-term capital gains, in which case provisions of the Internal Revenue Code will treat our stockholders as having received, solely for tax purposes, our undistributed capital gains, and the stockholders will receive a corresponding credit for taxes that we paid on such undistributed capital gains. See “Taxation of UDR—Annual Distribution Requirements.” Corporate stockholders may be required to treat up to 20% of some capital gain dividends as ordinary income. Long-term capital gains are generally taxable at maximum federal rates of 15% (through 2012) in the case of stockholders that are individuals, trusts and estates, and 35% in the case of stockholders that are corporations. Capital gains attributable to the sale of depreciable real property held for more than 12 months are subject to a 25% maximum federal income tax rate for taxpayers who are taxed as individuals, to the extent of previously claimed depreciation deductions.

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

To the extent that we have available net operating losses and capital losses carried forward from prior tax years, such losses may reduce the amount of distributions that we must make in order to comply with the REIT distribution requirements. See “Taxation of UDR—Annual Distribution Requirements.” Such losses, however, are not passed through to stockholders and do not offset income of stockholders from other sources, nor would such losses affect the character of any distributions that we make, which are generally subject to tax in the hands of stockholders to the extent that we have current or accumulated earnings and profits.

Dispositions of UDR Stock. In general, capital gains recognized by individuals, trusts and estates upon the sale or disposition of our stock will be subject to a maximum federal income tax rate of 15% (through 2012) if the stock is held for more than one year, and will be taxed at ordinary income rates (of up to 35% through 2012) if the stock is held for one year or less. Gains recognized by stockholders that are corporations are subject to federal income tax at a maximum rate of 35%, whether or not such gains are classified as long-term capital gains. Capital losses recognized by a stockholder upon the disposition of our stock that was held for more than one year at the time of disposition will be considered long-term capital losses, and are generally available only to offset capital gain income of the stockholder but not ordinary income (except in the case of individuals, who may offset up to $3,000 of ordinary income each year). In addition, any loss upon a sale or exchange of shares of our stock by a stockholder who has held the shares for six months or less, after applying holding period rules, will be

treated as a long-term capital loss to the extent of distributions that we make that are required to be treated by the stockholder as long-term capital gain.

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

Moreover, you should be aware that we and other participants in the transactions in which we are involved (including their advisors) might be subject to disclosure or other requirements pursuant to these regulations.

Additional Medicare Tax on Unearned Income. With respect to taxable years beginning after December 31, 2012, certain taxable domestic stockholders, including individuals, estates and trusts, will be subject to an additional 3.8% Medicare tax on unearned income. For individuals, the additional Medicare tax applies to the lesser of (i) “net investment income” or (ii) the excess of “modified adjusted gross income” over $200,000 ($250,000 if married and filing jointly or $125,000 if married and filing separately). “Net investment income” generally equals the taxpayer’s gross investment income reduced by the deductions that are allocable to such income. Investment income generally includes passive income such as interest, dividends, annuities, royalties, rents, and capital gains. Investors are urged to consult their own tax advisors regarding the implications of the additional Medicare tax resulting from an investment in our stock.

Passive Activity Losses and Investment Interest Limitations. Distributions that we make and gain arising from the sale or exchange by a domestic stockholder of our stock will not be treated as passive activity income. As a result, stockholders will not be able to apply any “passive losses” against income or gain relating to our stock. To the extent that distributions we make do not constitute a return of capital, they will be treated as investment income for purposes of computing the investment interest limitation.

Taxation of Foreign Stockholders

The following is a summary of certain U.S. federal income and estate tax consequences of the ownership and disposition of our stock applicable to non-U.S. holders. A “non-U.S. holder” means a beneficial owner of a share of our stock that, for U.S. federal income tax purposes, is a non-resident alien individual, a foreign corporation, or a foreign estate or trust.

Ordinary Dividends. The portion of dividends received by a non-U.S. holder that is (1) payable out of our earnings and profits, (2) not attributable to our capital gains and (3) not effectively connected with a U.S. trade or business of the non-U.S. holder, will be subject to U.S. withholding tax at the rate of 30%, unless reduced or eliminated by treaty.

In general, non-U.S. holders will not be considered to be engaged in a U.S. trade or business solely as a result of their ownership of our stock. In cases where the dividend income from a non-U.S. holder’s investment in our stock is, or is treated as, effectively connected with the non-U.S. holder’s conduct of a U.S. trade or business, the non-U.S. holder generally will be subject to federal income tax at graduated rates, in the same manner as domestic stockholders are taxed with respect to such dividends. Such income generally must be reported on a U.S. income tax return filed by or on behalf of the non-U.S. holder. The income may also be subject to the 30% branch profits tax in the case of a non-U.S. holder that is a corporation.

Non-Dividend Distributions. Unless our stock constitutes a U.S. real property interest (a “USRPI”), distributions that we make which are not dividends out of our earnings and profits will not be subject to U.S. income tax. If we cannot determine at the time a distribution is made whether or not the distribution will exceed current and accumulated earnings and profits, the distribution will be subject to withholding at the rate

applicable to dividends. A non-U.S. holder may seek a refund from the IRS of any amounts withheld if it subsequently is determined that the distribution was, in fact, in excess of our current and accumulated earnings and profits. If our stock constitutes a USRPI, as described below, distributions that we make in excess of the sum of (a) the stockholder’s proportionate share of our earnings and profits, and (b) the stockholder’s basis in its stock, will be taxed under the Foreign Investment in Real Property Tax Act of 1980, or FIRPTA, at the rate of tax, including any applicable capital gains rates, that would apply to a domestic stockholder of the same type (e.g., an individual or a corporation, as the case may be), and the collection of the tax will be enforced by a refundable withholding at a rate of 10% of the amount by which the distribution exceeds the stockholder’s share of our earnings and profits.

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

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

Dispositions of UDR Stock. Unless our stock constitutes a USRPI, a sale of our stock by a non-U.S. holder generally will not be subject to U.S. taxation under FIRPTA. Our stock will not be treated as a USRPI if less than 50% of our assets throughout a prescribed testing period consist of interests in real property located within the United States, excluding, for this purpose, interests in real property solely in a capacity as a creditor.

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

In the event that we are not a domestically-controlled qualified investment entity, but our stock is “regularly traded,” as defined by applicable Treasury regulations, on an established securities market, a non-U.S. holder’s sale of our common stock nonetheless would not be subject to tax under FIRPTA as a sale of a USRPI, provided that the selling non-U.S. holder held 5% or less of our outstanding common stock any time during the one-year

period ending on the date of the sale. We expect that our common stock will be regularly traded on an established securities market.

If gain on the sale of our stock were subject to taxation under FIRPTA, the non-U.S. holder would be required to file a U.S. federal income tax return and would be subject to the same treatment as a U.S. stockholder with respect to such gain, subject to applicable alternative minimum tax and a special alternative minimum tax in the case of non-resident alien individuals, and the purchaser of the stock could be required to withhold 10% of the purchase price and remit such amount to the IRS.

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

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

The U.S. federal taxation of non-U.S. holders is a highly complex matter that may be affected by many other considerations. Accordingly, non-U.S. holders should consult their tax advisors regarding the income and withholding tax considerations with respect to owning UDR stock.

Taxation of Tax-Exempt Stockholders

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

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

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

generally should prevent a tax-exempt entity from owning more than 10% of the value of our stock and generally should prevent us from becoming a pension-held REIT.

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

Other Tax Considerations

Dividend Reinvestment Program

Stockholders participating in our common stock dividend reinvestment program are treated as having received the gross amount of any cash distributions which would have been paid by us to such stockholders had they not elected to participate in the program. These distributions will retain the character and tax effect applicable to distributions from us generally. Participants in the dividend reinvestment program are subject to U.S. federal income and withholding tax on the amount of the deemed distributions to the extent that such distributions represent dividends or gains, even though they receive no cash. Shares of our common stock received under the program will have a holding period beginning with the day after purchase, and a tax basis equal to their cost (which is the gross amount of the distribution).

Legislative or Other Actions Affecting REITs

The present federal income tax treatment of an investment in us may be modified by legislative, judicial or administrative action at any time and that any such action may affect investments and commitments previously made. The rules dealing with federal income taxation are constantly under review by persons involved in the legislative process, the IRS and the Treasury, resulting in revisions of regulations and revised interpretations of established concepts as well as statutory changes. Revisions in federal tax laws and interpretations of these laws could adversely affect the tax consequences of your investment.

In addition, legislation was enacted on March 18, 2010 that will impose a 30% U.S. withholding tax on U.S. source dividends and on the gross proceeds from a disposition of property that produces such income, paid to a foreign financial institution, unless such institution enters into an agreement with the U.S. Treasury Department to collect and provide to the Treasury Department certain information regarding U.S. account holders, including certain account holders that are foreign entities with U.S. owners, with such institution. The legislation also generally imposes a withholding tax of 30% on such amounts when paid to a non-financial foreign entity unless such entity provides the withholding agent with a certification that it does not have any substantial U.S. owners or a certification identifying the direct and indirect substantial U.S. owners of the entity. Under certain circumstances, a taxpayer may be eligible for refunds or credits of such taxes. These withholding and reporting requirements generally will apply to payments made after December 31, 2012. However, the withholding tax will not be imposed on payments pursuant to debt obligations outstanding as of March 18, 2012 and the IRS has issued a notice indicating that any withholding obligations will begin no earlier than January 2014.

Recently enacted legislation has also temporarily shortened the recognition period during which the disposition of any asset we acquire from a “C” corporation in a transaction in which the basis of the asset in our hands is determined by reference to the basis of the asset (or any other property) in the hands of the C corporation will cause gain to be taxed at the highest regular corporate rate to the extent of any built-in, unrealized capital gain at the time of the acquisition. For the 2011 taxable year, the recognition period is shortened from 10 years to 5 years if the fifth taxable year of the recognition period preceded such taxable year.

Stockholders are urged to consult with their tax advisors regarding the possible implications of this recently enacted legislation on their ownership and disposition of our common stock.

State, Local and Foreign Taxes

We and our subsidiaries and stockholders may be subject to state, local or foreign taxation in various jurisdictions including those in which we or they transact business, own property or reside. We may own properties located in numerous jurisdictions, and may be required to file tax returns in some or all of those jurisdictions. Our state, local or foreign tax treatment and that of our stockholders may not conform to the federal income tax treatment discussed above. We may pay foreign property taxes, and dispositions of foreign property or operations involving, or investments in, foreign property may give rise to foreign income or other tax liability in amounts that could be substantial. Any foreign taxes that we incur do not pass through to stockholders as a credit against their U.S. federal income tax liability. Prospective investors should consult their tax advisors regarding the application and effect of state, local and foreign income and other tax laws on an investment in our stock.

SELLING SECURITY HOLDERS

Information about selling security holders, where applicable, will be set forth in a prospectus supplement, in a post-effective amendment, or in filings we make with the SEC under the Exchange Act which are incorporated by reference.

PLAN OF DISTRIBUTION

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

•

directly to one or more purchasers;

•

through agents;

•

to or through underwriters, brokers or dealers;

•

through a combination of any of these methods.

A distribution of the securities offered by this prospectus may also be effected through the issuance of derivative securities, including without limitation, warrants, subscriptions, exchangeable securities, forward delivery contracts and the writing of options.

In addition, the manner in which we may sell some or all of the securities covered by this prospectus includes, without limitation, through:

•

a block trade in which a broker-dealer will attempt to sell as agent, but may position or resell a portion of the block, as principal, in order to facilitate the transaction;

•

purchases by a broker-dealer, as principal, and resale by the broker-dealer for its account;

•

ordinary brokerage transactions and transactions in which a broker solicits purchasers; or

•

privately negotiated transactions.

We may also enter into hedging transactions. For example, we may:

•

enter into transactions with a broker-dealer or affiliate thereof in connection with which such broker-dealer or affiliate will engage in short sales of the common stock pursuant to this prospectus, in which case such broker-dealer or affiliate may use shares of common stock received from us to close out its short positions;

•

sell securities short and redeliver such shares to close out our short positions;

•

enter into option or other types of transactions that require us to deliver common stock to a broker-dealer or an affiliate thereof, who will then resell or transfer the common stock under this prospectus; or

•

loan or pledge the common stock to a broker-dealer or an affiliate thereof, who may sell the loaned shares or, in an event of default in the case of a pledge, sell the pledged shares pursuant to this prospectus.

In addition, we may enter into derivative or hedging transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. In connection with such a transaction, the third parties may sell securities covered by and pursuant to this prospectus and an applicable prospectus supplement or pricing supplement, as the case may be. If so, the third party may use securities borrowed from us or others to settle such sales and may use securities received from us to close out any related short positions. We may also loan or pledge securities covered by this prospectus and an applicable prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities pursuant to this prospectus and the applicable prospectus supplement or pricing supplement, as the case may be.

A prospectus supplement with respect to each offering of securities will state the terms of the offering of the securities, including:

•

the name or names of any underwriters or agents and the amounts of securities underwritten or purchased by each of them, if any;

•

the public offering price or purchase price of the securities and the net proceeds to be received by us from the sale;

•

any delayed delivery arrangements;

•

any underwriting discounts or agency fees and other items constituting underwriters’ or agents’ compensation;

•

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

•

any securities exchange or markets on which the securities may be listed.

The offer and sale of the securities described in this prospectus by us, the underwriters or the third parties described above may be effected from time to time in one or more transactions, including privately negotiated transactions, either:

•

at a fixed price or prices, which may be changed;

•

at market prices prevailing at the time of sale;

•

at prices related to the prevailing market prices; or

•

at negotiated prices.

General

Any public offering price and any discounts, commissions, concessions or other items constituting compensation allowed or reallowed or paid to underwriters, dealers, agents or remarketing firms may be changed from time to time. Underwriters, dealers, agents and remarketing firms that participate in the distribution of the offered securities may be “underwriters” as defined in the Securities Act. Any discounts or commissions they receive from us and any profits they receive on the resale of the offered securities may be treated as underwriting discounts and commissions under the Securities Act. We will identify any underwriters, agents or dealers and describe their commissions, fees or discounts in the applicable prospectus supplement or pricing supplement, as the case may be.

Underwriters and Agents

If underwriters are used in a sale, they will acquire the offered securities for their own account. The underwriters may resell the offered securities in one or more transactions, including negotiated transactions.

These sales may be made at a fixed public offering price or prices, which may be changed, at market prices prevailing at the time of the sale, at prices related to such prevailing market price or at negotiated prices. We may offer the securities to the public through an underwriting syndicate or through a single underwriter. The underwriters in any particular offering will be mentioned in the applicable prospectus supplement or pricing supplement, as the case may be.

Unless otherwise specified in connection with any particular offering of securities, the obligations of the underwriters to purchase the offered securities will be subject to certain conditions contained in an underwriting agreement that we will enter into with the underwriters at the time of the sale to them. The underwriters will be obligated to purchase all of the securities of the series offered if any of the securities are purchased, unless otherwise specified in connection with any particular offering of securities. Any initial offering price and any discounts or concessions allowed, reallowed or paid to dealers may be changed from time to time.

We may designate agents to sell the offered securities. Unless otherwise specified in connection with any particular offering of securities, the agents will agree to use their best efforts to solicit purchases for the period of their appointment. We may also sell the offered securities to one or more remarketing firms, acting as principals for their own accounts or as agents for us. These firms will remarket the offered securities upon purchasing them in accordance with a redemption or repayment pursuant to the terms of the offered securities. A prospectus supplement or pricing supplement, as the case may be will identify any remarketing firm and will describe the terms of its agreement, if any, with us and its compensation.

In connection with offerings made through underwriters or agents, we may enter into agreements with such underwriters or agents pursuant to which we receive our outstanding securities in consideration for the securities being offered to the public for cash. In connection with these arrangements, the underwriters or agents may also sell securities covered by this prospectus to hedge their positions in these outstanding securities, including in short sale transactions. If so, the underwriters or agents may use the securities received from us under these arrangements to close out any related open borrowings of securities.

Dealers

We may sell the offered securities to dealers as principals. We may negotiate and pay dealers’ commissions, discounts or concessions for their services. The dealer may then resell such securities to the public either at varying prices to be determined by the dealer or at a fixed offering price agreed to with us at the time of resale. Dealers engaged by us may allow other dealers to participate in resales.

Direct Sales

We may choose to sell the offered securities directly. In this case, no underwriters or agents would be involved.

Institutional Purchasers

We may authorize agents, dealers or underwriters to solicit certain institutional investors to purchase offered securities on a delayed delivery basis pursuant to delayed delivery contracts providing for payment and delivery on a specified future date. The applicable prospectus supplement or pricing supplement, as the case may be will provide the details of any such arrangement, including the offering price and commissions payable on the solicitations.

We will enter into such delayed contracts only with institutional purchasers that we approve. These institutions may include commercial and savings banks, insurance companies, pension funds, investment companies and educational and charitable institutions.

Indemnification; Other Relationships

We may have agreements with agents, underwriters, dealers and remarketing firms to indemnify them against certain civil liabilities, including liabilities under the Securities Act. Agents, underwriters, dealers and remarketing firms, and their affiliates, may engage in transactions with, or perform services for, us in the ordinary course of business. This includes commercial banking and investment banking transactions.

Market-Making, Stabilization and Other Transactions

There is currently no market for any of the offered securities, other than the common stock and the 6.75% Series G Cumulative Redeemable Preferred Stock which are both listed on the NYSE. If the offered securities are traded after their initial issuance, they may trade at a discount from their initial offering price, depending upon prevailing interest rates, the market for similar securities and other factors. While it is possible that an underwriter could inform us that it intends to make a market in the offered securities, such underwriter would not be obligated to do so, and any such market-making could be discontinued at any time without notice. Therefore, no assurance can be given as to whether an active trading market will develop for the offered securities. We have no current plans for listing of the debt securities, preferred stock or warrants on any securities exchange or on the National Association of Securities Dealers, Inc. automated quotation system; any such listing with respect to any particular debt securities, preferred stock or warrants will be described in the applicable prospectus supplement or pricing supplement, as the case may be.

In connection with any offering of common stock, the underwriters may purchase and sell shares of common stock in the open market. These transactions may include short sales, syndicate covering transactions and stabilizing transactions. Short sales involve syndicate sales of common stock in excess of the number of shares to be purchased by the underwriters in the offering, which creates a syndicate short position. “Covered” short sales are sales of shares made in an amount up to the number of shares represented by the underwriters’ over-allotment option. In determining the source of shares to close out the covered syndicate short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option. Transactions to close out the covered syndicate short involve either purchases of the common stock in the open market after the distribution has been completed or the exercise of the over-allotment option. The underwriters may also make “naked” short sales of shares in excess of the over-allotment option. The underwriters must close out any naked short position by purchasing shares of common stock in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of bids for or purchases of shares in the open market while the offering is in progress for the purpose of pegging, fixing or maintaining the price of the securities.

In connection with any offering, the underwriters may also engage in penalty bids. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.

Fees and Commissions

In compliance with the guidelines of the Financial Industry Regulatory Authority (the “FINRA”), the aggregate maximum discount, commission or agency fees or other items constituting underwriting compensation to be received by any FINRA member or independent broker-dealer will not exceed 8% of any offering pursuant to this prospectus and any applicable prospectus supplement or pricing supplement, as the case may be; however, it is anticipated that the maximum commission or discount to be received in any particular offering of securities will be significantly less than this amount.

If more than 10% of the net proceeds of any offering of securities made under this prospectus will be received by FINRA members participating in the offering or affiliates or associated persons of such FINRA members, the offering will be conducted in accordance with FINRA Conduct Rule 2710(h)

LEGAL MATTERS

Unless otherwise indicated in the applicable prospectus supplement, Morrison & Foerster LLP, New York, New York will provide opinions regarding the authorization and validity of the securities and certain U.S. federal income tax matters, and certain U.S. federal income tax matters will be passed upon for us by Kutak Rock LLP, Little Rock, Arkansas. Any underwriters will also be advised about legal matters by their own counsel, which will be named in the prospectus supplement.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, any accompanying prospectus supplements and the documents incorporated by reference contain forward-looking statements that involve risks and uncertainties, which are based on beliefs, expectations, estimates, projections, forecasts, plans, anticipations, targets, outlooks, initiatives, visions, objectives, strategies, opportunities, drivers and intents of our management. Such statements are made in reliance upon the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.

Our actual results may differ materially from those discussed in such forward-looking statements.

Statements that are not historical facts, including statements about our beliefs and expectations, are forward-looking statements. Forward-looking statements can be identified by, among other things, the use of forward-looking language, such as “believes,” “expects,” “estimates,” “projects,” “forecasts,” “plans,” “anticipates,” “targets,” “outlooks,” “initiatives,” “visions,” “objectives,” “strategies,” “opportunities,” “drivers,” “intends,” “scheduled to,” “seeks,” “may,” “will,” or “should” or the negative of those terms, or other variations of those terms or comparable language, or by discussions of strategy, plans, targets, models or intentions. Forward-looking statements speak only as of the date they are made, and except for our ongoing obligations under the U.S. federal securities laws, we undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise. Such forward-looking statements include, without limitation, statements concerning property acquisitions and dispositions, development activity and capital expenditures, capital raising activities, rent growth, occupancy, and rental expense growth. In addition to factors that may be described in this prospectus, any accompanying prospectus supplement and the documents

incorporated by reference, our determination not to, or difficulties, delays or unanticipated costs in or our inability to, including as a result of unanticipated adverse business developments affecting us, or our properties, adverse changes in the real estate markets and general and local economies and business conditions, among others factors, could cause our actual results to differ materially from those expressed in any forward-looking statements made by us.
