Ladies and Gentlemen:

     UDR, Inc., a Maryland corporation (the “Company”), and United Dominion Realty, L.P., a Delaware limited partnership (the “Operating Partnership”), each confirms its agreement with Citigroup Global Markets Inc., Deutsche Bank Securities Inc., J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, Morgan Stanley & Co. Incorporated and Wells Fargo Securities, LLC (each, an “Agent,” and together, the “Agents”) with respect to the issue and sale by the Company of its Medium-Term Notes, Series A, Due Nine Months or More From Date of Issue (the “Notes”). The Notes will be fully and unconditionally guaranteed as to payment of the principal thereof, and premium, if any, and interest thereon (the “Guarantee” and, together with the Notes, the “Securities”) by the Operating Partnership. The Securities will be issued pursuant to an indenture, dated as of November 1, 1995, between the Company (successor by merger to United Dominion Realty Trust, Inc., a Virginia corporation) and U.S. Bank National Association (successor trustee to Wachovia Bank, National Association, formerly known as First Union National Bank of Virginia), as trustee (the “Trustee”), as supplemented by the first supplemental indenture thereto, dated as of May 3, 2011, among the Operating Partnership, the Company and the Trustee (such indenture, as supplemented and as further

amended, supplemented and modified from time to time, the “Indenture”). All references herein to any “subsidiary” or “subsidiaries” of the Company shall be deemed to include the Operating Partnership unless otherwise expressly stated.

     This Agreement provides both for the sale of the Securities by the Company to one or more Agents as principal for resale to investors and other purchasers and for the sale of the Securities by the Company directly to investors (as may from time to time be agreed to by the Company and the applicable Agent), in which case such Agent will act as an agent of the Company in soliciting purchases of the Securities.

     The Company and the Operating Partnership have filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3 (No. 333-156002), as amended by Post-Effective Amendment No. 1 thereto on October 15, 2010, which provides for the registration of securities (including the Notes), and guarantees of the Operating Partnership, including the Guarantee, under the Securities Act of 1933, as amended (the “1933 Act”), and the offering thereof from time to time in accordance with Rule 415 of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”), and the Company and the Operating Partnership have filed such post-effective amendments thereto as may have been required prior to the Company’s acceptance of an offer to purchase the Securities. Such registration statement (as so amended), including any document incorporated therein by reference pursuant to the Securities Exchange Act of 1934, as amended (the “1934 Act”), and any prospectus, prospectus supplement and/or pricing supplement deemed or retroactively deemed to be a part thereof that has not been superseded or modified is referred to herein as the “Registration Statement.” “Registration Statement” without reference to a time means the Registration Statement as of the time of the first contract of sale of any issue of the Securities, which time shall be considered the “effective date” of the Registration Statement with respect to such Securities. For purposes of the definition of Registration Statement as used herein, information contained in a form of prospectus, prospectus supplement or pricing supplement that is deemed retroactively to be a part of the Registration Statement pursuant to Rule 430B of the 1933 Act Regulations (“Rule 430B”) shall be considered to be included in the Registration Statement at the time specified in Rule 430B. The prospectus supplement relating to the series of Securities and the base prospectus and all applicable amendments or supplements thereto, in each case immediately prior to the Applicable Time (as defined in the applicable Terms Agreement), including any document incorporated by reference therein, is herein called the “Statutory Prospectus.” The “Prospectus” means the Statutory Prospectus and the final pricing supplement in the form first filed with the Commission pursuant to Rule 424(b) of the 1933 Act Regulations (“Rule 424(b)”) that discloses the public offering price and other final terms of the Securities of any issue and otherwise satisfies Section 10(a) of the 1933 Act. A “preliminary prospectus” shall be deemed to refer to any prospectus, any prospectus supplement and any pricing supplement used before the acceptance by the Company of an offer for the purchase of the Securities which omitted information to be included upon pricing in a form of prospectus filed with the Commission pursuant to Rule 424(b). For purposes of this Agreement, all references to the Registration Statement, Statutory Prospectus, Prospectus or preliminary prospectus or to any amendment or supplement thereto shall be deemed to include any copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”).

     All references in this Agreement to financial statements and schedules and other information which is “disclosed,” “contained,” “included” or “stated” (or other references of like import) in the Registration Statement, Statutory Prospectus, Prospectus or preliminary prospectus shall be deemed to include all such financial statements and schedules and other information which is incorporated by reference in or otherwise deemed by the 1933 Act Regulations to be a part of or included in the Registration Statement, Statutory Prospectus, Prospectus or preliminary prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, Statutory Prospectus, Prospectus or preliminary prospectus shall be deemed to include the filing of any document under the 1934 Act which is incorporated by reference in or otherwise deemed by the 1933 Act Regulations to be a part of or included in the Registration Statement, Statutory Prospectus, Prospectus or preliminary prospectus, as the case may be.

SECTION 1. Appointment as Agents .

     (a)  Appointment . Subject to the terms and conditions stated herein and subject to the reservation by the Company of the right to sell Securities directly on its own behalf, the Company hereby agrees that the Securities will be sold to or through the Agents. Notwithstanding any provision herein to the contrary, the Company reserves the right to appoint additional agents for the offer and sale of Securities, which agency may be on an on-going basis or on a one-time basis. Any such additional agent shall become a party to this Agreement and shall thereafter be subject to the provisions hereof and entitled to the benefits hereunder upon the execution of a counterpart hereof or other form of acknowledgement of its appointment hereunder, including the form of letter attached hereto as Exhibit B, and delivery to the Company of addresses for notice hereunder and under the Procedures.

     (b)  Sale of Securities . The Company shall not sell or approve the solicitation of purchases of Securities in excess of the amount which shall be authorized by the Company from time to time. The Agents shall have no responsibility for maintaining records with respect to the aggregate initial offering price of Securities sold, or of otherwise monitoring the availability of Securities for sale, under the Registration Statement.

     (c)  Purchases as Principal . The Agents shall not have any obligation to purchase Securities from the Company as principal, but one or more Agents may agree from time to time to purchase Securities as principal for resale to investors and other purchasers determined by such Agent or Agents. Any such purchase of Securities from the Company by an Agent as principal shall be made in accordance with Section 3(a) hereof.

     (d)  Solicitations as Agents . If agreed upon by an Agent and the Company, such Agent, acting solely as agent for the Company and not as principal, will solicit purchases of the Securities. Unless otherwise instructed by the Company, such Agent will communicate to the Company, orally, each offer to purchase Securities solicited by it on an agency basis other than those offers rejected by such Agent. Such Agent shall have the right, in its discretion reasonably exercised, to reject any proposed purchase of Securities, as a whole or in part, and any such rejection shall not be deemed a breach of its agreement contained herein. The Company may accept or reject any proposed purchase of Securities, in whole or in part. Such Agent shall make reasonable efforts to assist the Company in obtaining performance by each purchaser whose

offer to purchase Securities has been solicited by it and accepted by the Company. Such Agent shall not have any liability to the Company in the event that any such purchase is not consummated for any reason. If the Company shall default on its obligation to deliver Securities to a purchaser whose offer it has accepted, the Company shall (i) hold such Agent harmless against any loss, claim or damage arising from or as a result of such default by the Company and (ii) pay to such Agent any commission to which it would otherwise be entitled absent such default.

     (e)  Reliance . The Company and the Agents agree that any Securities purchased from the Company by one or more Agents as principal shall be purchased, and any Securities the placement of which an Agent arranges as agent of the Company shall be placed by such Agent, in reliance on the representations, warranties, covenants and agreements of the Company and the Operating Partnership contained herein and on the terms and conditions and in the manner provided herein.

SECTION 2. Representations and Warranties .

No stop order suspending the effectiveness of the Registration Statement, or notice objecting to its use, has been issued under the 1933 Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company and the Operating Partnership, are contemplated by the Commission, and any request on the part of the Commission for additional information has been complied with; the Indenture has been duly qualified under the Trust Indenture Act of 1939 as amended (the “1939 Act”); at the respective times that the Registration Statement and any post-effective amendment thereto (including the filing of the Company’s most recent Annual Report on Form 10-K with the Commission (the “Annual Report on Form 10-K”)) became effective, at each deemed effective date with respect to the Agents pursuant to Rule 430B(f)(2) of the 1933 Act Regulations and at the date hereof, the Registration Statement and any amendments thereto complied in all material respects with the requirements of the 1933 Act, the 1933 Act Regulations, the 1939 Act and the rules and regulations of the Commission under the 1939 Act (the “1939 Act Regulations”) and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; each preliminary prospectus and the Statutory Prospectus filed as part of the Registration Statement as originally filed or as part of any amendment thereto, or filed pursuant to Rule 424 under the 1933 Act Regulations, complied when so filed in all material respects with the 1933 Act Regulations; each preliminary prospectus and the Statutory Prospectus delivered to the applicable Agent(s) for use in connection with the offering of Securities are identical to any electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T; and at the date hereof, at the date of the Statutory Prospectus and at each Representation Date, neither the Statutory Prospectus nor any amendment or supplement thereto included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

     Any offer that is a “written communication” as defined in Rule 405 relating to the Securities made prior to the filing of the Registration Statement by the Company or any person acting on its behalf (within the meaning, for this paragraph only, of Rule 163(c)) has been filed with the Commission in accordance with the exemption provided by Rule 163 and otherwise complied with the requirements of Rule 163, including without limitation the legending requirement, to qualify such offer for the exemption from Section 5(c) of the 1933 Act provided by Rule 163.

SECTION 3. Purchases as Principal; Solicitations as Agent .

     (a)  Purchases as Principal .

     Each sale of Securities to an Agent shall be made in accordance with the terms of this Agreement and the Procedures (as defined in Section 3(c) below) and a supplemental agreement which will provide for the sale of such Securities to, and the purchase and reoffering thereof by, an Agent. Each such supplemental agreement (which may be an oral agreement and confirmed in writing between an Agent and the Company and the Operating Partnership) is herein referred to as a “Terms Agreement”. Each such Terms Agreement, whether oral (and confirmed in writing, which may be by facsimile transmission) or in writing, shall be with respect to such information (as applicable) as is specified in Exhibit A hereto. An Agent’s commitment to purchase Securities shall be deemed to have been made on the basis of the representations and

SECTION 4. Covenants of the Company and the Operating Partnership .

     The Company and the Operating Partnership covenant with the Agents as follows:

     (a) The Company and the Operating Partnership will file each Statutory Prospectus pursuant to and in accordance with Rule 424(b) within the time period prescribed therein. Prior to the termination of the offering of any issue of Securities, the Company and the Operating Partnership will not file any amendment to the Registration Statement or supplement to the Prospectus or Statutory Prospectus (except for a supplement relating to an offering of securities other than the Securities) unless the Company and the Operating Partnership have furnished to the related Agent(s) a copy for their review prior to filing and will not file any such proposed amendment or supplement to which such Agent(s) may reasonably object. Subject to the foregoing sentence, the Company and the Operating Partnership will cause each supplement to the Prospectus or Statutory Prospectus to be filed (or mailed for filing) with the Commission as required pursuant to Rule 424 of the 1933 Act Regulations (without reliance on Rule 424(b)(8)). The Company and the Operating Partnership will promptly advise such Agent(s) (i) when each supplement to the Prospectus or Statutory Prospectus shall have been filed (or mailed for filing) with the Commission pursuant to Rule 424 of the 1933 Act Regulations (the filing of any such supplement on EDGAR shall be deemed notice by the Company and the Operating Partnership to the Agents), (ii) when any amendment to the Registration Statement shall have become effective (for so long as the Registration Statement is an “automatic shelf registration statement” within the meaning of Rule 405, the filing of any such amendment on EDGAR shall be deemed notice of effectiveness by the Company and the Operating Partnership to the Agents), (iii) of any request by the Commission for any amendment to the Registration Statement or amendment to or supplement to the Prospectus or Statutory Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or threatening of any proceeding for that purpose or of any examination pursuant to Section 8(e) of the 1933 Act with respect to the Registration Statement, (v) if the Company or the Operating Partnership becomes the subject of a proceeding under Section 8A of the 1933 Act in connection with the offering of the Securities, (vi) of the receipt by the Company or the Operating Partnership of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose and (vii) any change in the rating assigned by any nationally recognized statistical rating organization to any debt securities of the Company or the public announcement by any nationally recognized statistical rating organization that it has under surveillance or review, with possible negative implications, its rating of any debt securities of the Company. The Company and the Operating Partnership will use their best efforts to prevent the issuance of any such stop order and, if issued, to obtain as soon as possible the withdrawal thereof. The Company and the Operating Partnership shall pay the required Commission filing fees relating to the Securities within the time required by Rule 456(b)(1)(i) of the 1933 Act Regulations without regard to the proviso therein and otherwise in accordance with

Rules 456(b) and 457(r) of the 1933 Act Regulations (including, if applicable, by updating the “Calculation of Registration Fee” table in accordance with Rule 456(b)(1)(ii) of the 1933 Act Regulations either in a post-effective amendment to the Registration Statement or on the cover page of a prospectus filed pursuant to Rule 424(b)).

     (b) The Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405, that initially became effective within three years of the date hereof. If immediately prior to the third anniversary (the “Renewal Deadline”) of the initial effective date of the automatic shelf registration statement relating to the Securities, any of the Securities remain unsold by the Agent(s), the Company and the Operating Partnership will, prior to the Renewal Deadline, file, if it has not already done so and is eligible to do so, a new automatic shelf registration statement relating to the Securities, in a form satisfactory to the Agents. If the Company and the Operating Partnership are no longer eligible to file an automatic shelf registration statement, the Company and the Operating Partnership will, prior to the Renewal Deadline, if they have not already done so, file a new shelf registration statement relating to the Securities, in a form satisfactory to the Agents, and will use their best efforts to cause such registration statement to be declared effective within 180 days after the Renewal Deadline. The Company and the Operating Partnership will take all other action necessary or appropriate to permit the public offering and sale of the Securities to continue as contemplated in the expired registration statement relating to the Securities. References herein to the Registration Statement shall include such new automatic shelf registration statement or such new shelf registration statement, as the case may be.

     (c) If, at any time when a prospectus relating to the Securities is required to be (or, but for the exemption in Rule 172 of the 1933 Act Regulations, would be required to be) delivered under the 1933 Act, any event occurs as a result of which the Registration Statement, General Disclosure Package or the Prospectus, as then supplemented, would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading, any facts or events arise which, individually or in the aggregate, would represent a fundamental change in the information set forth in the Registration Statement, the General Disclosure Package or the Prospectus, or if it shall be necessary to amend the Registration Statement, file a new registration statement or to supplement the Prospectus to comply with the 1933 Act or the 1934 Act or the respective rules and regulations thereunder, the Company and the Operating Partnership promptly will (i) notify such Agent to suspend the solicitation of offers to purchase Securities (and, if so notified, such Agent shall forthwith suspend such solicitation and cease using the Prospectus as then amended or supplemented), (ii) prepare and file with the Commission, subject to the first sentence of paragraph (a) of this Section 4, an amendment or supplement or new registration statement which will correct such statement or omission or an amendment or supplement which will effect such compliance and (iii) will supply any such amended or supplemented Prospectus or new registration statement to such Agent in such quantities as such Agent may reasonably request. If such amendment or supplement, and any documents, certificates and opinions furnished to such Agent pursuant to paragraph (i) of this Section 4 in connection with the preparation or filing of such amendment or supplement are reasonably satisfactory in all respects to such Agent, such Agent will, upon the filing of such amendment or supplement with the Commission and upon the effectiveness of an amendment to the Registration Statement (or new registration statement) if such an amendment is required, resume such Agent’s obligation to solicit offers to purchase Securities hereunder. If

at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information then contained in the Registration Statement or Prospectus or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company and the Operating Partnership will (i) promptly notify the applicable Agent(s) and (ii) promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

     (d) With respect to any issue of Securities, the Company and the Operating Partnership represent and agree that, unless they obtain the prior written consent of the related Agent(s), they will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, that is required to be filed with the Commission or retained by the Company and the Operating Partnership under Rule 433; provided that the prior written consent of the Agent(s) hereto shall be deemed to have been given in respect to the Issuer Free Writing Prospectus(es) listed in the applicable Terms Agreement. Any such free writing prospectus consented to by such Agent(s) is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company and the Operating Partnership represent that they have treated and agree that they will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping.

     (e) The Company will prepare a final term sheet relating to the final terms of the Securities, in the form attached to the form of Terms Agreement, and will file such final term sheet within the period required by Rule 433(d)(5)(ii). Any such final term sheet is an Issuer Free Writing Prospectus and a Permitted Free Writing Prospectus for purposes of this Agreement. In addition to the foregoing, the Agent may, without consent of the Company or the Operating Partnership, use a free writing prospectus that contains only (a) (i) information describing the preliminary terms of the Securities or their offering, (ii) information that describes the final terms of the Securities or their offering and that is included in the final term sheet of the Company and the Operating Partnership contemplated in the first sentence of this subsection or (iii) information permitted by Rule 134 under the 1933 Act or (b) other information that is not “issuer information,” as defined in Rule 433.

     (f) The Company will deliver to the Agents as many signed and conformed copies of the Registration Statement (as originally filed) and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated by reference in the Prospectus) as the Agents reasonably request. The Company will furnish to the Agents as many copies of the Prospectus and any Issuer Free Writing Prospectus (in each case, as amended or supplemented) as the Agents reasonably request so long as the Agents are required to deliver a Prospectus in connection with sales or solicitations of offers to purchase the Securities.

     (g) As soon as practicable, but in any event not later than 16 months after any Settlement Date, the Company and the Operating Partnership will make generally available to the Company’s security holders and to the Agents earnings statements covering a period of at least 12 months beginning after the effective date of the Registration Statement and otherwise satisfying the provisions of and provide the benefits contemplated by Section 11(a) of the 1933 Act and Rule 158 under the 1933 Act.

     (h) The Company and the Operating Partnership will endeavor, in cooperation with the Agents, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions of the United States as the Agents may designate, and will maintain such qualifications in effect for as long as may be required for the distribution of the Securities; provided , however , that the Company and the Operating Partnership shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation in any jurisdiction in which they are not so qualified. The Company and the Operating Partnership will file such statements and reports as may be required by the laws of each jurisdiction in which the Securities have been qualified as above provided. The Company will promptly advise the Agents of the receipt by the Company or the Operating Partnership of any notification with respect to the suspension of the qualification of the Securities for sale in any such state or jurisdiction or the initiating or threatening of any proceeding for such purpose.

     (i) The Company and the Operating Partnership, during the period when the Prospectus is required to be delivered under the 1933 Act or the 1934 Act in connection with sales of the Securities (or but for the exemption afforded by Rule 172 of the 1933 Act would be required to be delivered), will file all documents required to be filed with the Commission pursuant to Sections 13, 14 or 15(d) of the 1934 Act within the time periods prescribed by the 1934 Act and the rules and regulations of the Commission thereunder (the “1934 Act Regulations”).

     (j) If specified by the applicable Agent or Agents in connection with a purchase of Securities from the Company as principal, between the date of the agreement to purchase such Securities and the Settlement Date with respect to such purchase, the Company will not, without the prior written consent of such Agent or Agents, offer or sell, grant any option for the sale of, or enter into any agreement to sell, any debt securities of the Company (other than the Securities that are to be sold pursuant to such agreement, commercial paper in the ordinary course of business or assumptions of mortgages on acquired properties).

     (k) The Company will continue to elect to qualify as a “real estate investment trust” under the Code and will use its best efforts to continue to qualify as a “real estate investment trust” for so long as the Company’s board of directors deems it in the best interest of the Company and its shareholders to remain so qualified.

     (b)  Subsequent Delivery of Certificates . Each time that (i) the Registration Statement or the Statutory Prospectus shall be amended or supplemented (other than by an amendment or supplement providing solely for a change in the interest rate or formula applicable to the Securities or relating solely to the issuance and/or offering of securities other than the Securities), (ii) there is filed with the Commission any document incorporated by reference into the Registration Statement, the General Disclosure Package or the Prospectus (other than any Current Report on Form 8-K relating solely to the issuance and/or offering of securities other than the Securities, unless the Agents shall otherwise specify), (iii) (if required in connection with the purchase of Securities from the Company by one or more Agents as principal) the Company sells Securities to such Agent or Agents as principal or (iv) the Company sells Securities in a form not previously certified to the Agents by the Company, the Company and the Operating Partnership shall furnish or cause to be furnished to the Agent(s), forthwith a certificate dated the date of filing with the Commission of such supplement or document, the date of effectiveness of such amendment, or the date of such sale, as the case may be, in form satisfactory to the Agent(s) to the effect that the statements contained in the certificate referred to in Section 5(b) hereof which were last furnished to the Agents are true and correct at the time of such amendment, supplement, filing or sale, as the case may be, as though made at and as of such time (except that such statements shall be deemed to relate to the Registration Statement, the General Disclosure Package and the Prospectus as amended and supplemented to such time) or, in lieu of such certificate, a certificate of the same tenor as the certificate referred to in Section 5(b) hereof, modified as necessary to relate to the Registration Statement, the General Disclosure Package and the Prospectus as amended and supplemented to the time of delivery of such certificate.

     (c)  Subsequent Delivery of Legal Opinions . Each time that (i) the Registration Statement or the Statutory Prospectus shall be amended or supplemented (other than by an amendment or supplement providing solely for a change in the interest rate or formula applicable to the Securities, providing solely for the inclusion of additional financial information, or, unless the Agents shall otherwise specify, relating solely to the issuance and/or offering of securities other than the Securities), (ii) there is filed with the Commission any document incorporated by reference into the Registration Statement, General Disclosure Package or the Prospectus (other than any Current Report on Form 8-K relating solely to the issuance and/or offering of securities other than the Securities, unless the Agents shall otherwise specify), (iii) (if required in connection with the purchase of Securities from the Company by one or more Agents as principal) the Company sells Securities to such Agent or Agents as principal or (iv) the Company sells Securities in a form not previously certified to the Agents by the Company, the Company and the Operating Partnership shall furnish or cause to be furnished forthwith to the Agents and

to counsel to the Agents the written opinion of Morrison & Foerster LLP, counsel to the Company, or other counsel satisfactory to the Agents, dated the date of filing with the Commission of such supplement or document, the date of effectiveness of such amendment, or the date of such sale, as the case may be, in form and substance satisfactory to the Agents, of the same tenor as the opinion referred to in Section 5(a)(i) hereof (and including the statement required by Section 5(a)(iv)), but modified to state that (x) the Registration Statement has become effective under the 1933 Act; any required filing of the preliminary prospectus or the Statutory Prospectus, and any supplements thereto, pursuant to Rule 424(b) has been made in the manner and within the time period required by Rule 424(b); any required filing of any Issuer Free-Writing Prospectus pursuant to Rule 433(b) has been made in the manner and within the time period required by Rule 433(b); to the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement, or notice objecting to its use, has been issued, no proceedings for that purpose have been instituted or threatened and the Registration Statement, the preliminary prospectus, the Statutory Prospectus and any such Issuer Free Writing Prospectus (other than (i) the financial statements and other financial and statistical information contained therein and (ii) the Statement of Eligibility on Form T-1 filed as an exhibit thereto, as to which such counsel need express no opinion), as of their respective effective or issue dates, as the case may be, complied as to form in all material respects with the applicable requirements of the 1933 Act and the 1933 Act Regulations and the 1939 Act and the 1939 Act Regulations of the Commission thereunder and (y) no facts have come to such counsel’s attention that have caused it to believe that (A) the Registration Statement, at the later of the time of the filing of the Annual Report on Form 10-K or as of the “new effective date” with respect to the Agents and the Securities pursuant to, and within the meaning of, Rule 430B(f)(2) under the 1933 Act, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and (B) (1) the General Disclosure Package, as of the Applicable Time specified in the applicable Terms Agreement and (2) the Prospectus, as of its date and as of the Closing Date, included or includes, as the case may be, any untrue statement of material fact or omitted or omits, as the case may be, to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

     (d)  Delivery of Comfort Letters . Each time that the Agents purchase Securities from the Company as principal or solicit offers to purchase Securities as agent of the Company, the Agents shall receive (1) a letter from Ernst & Young LLP, dated as of the date of the applicable pricing supplement, in form and substance satisfactory to the Agents, to the effect that: (i) they are independent accountants with respect to the Company and its subsidiaries within the meaning of the 1933 Act and the applicable published rules and regulations thereunder; (ii) it is their opinion that the consolidated financial statements and supporting schedules of the Company and its subsidiaries included or incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus as amended and supplemented to the date of such letter, and covered by their opinions therein comply in form in all material respects with the applicable accounting requirements of the 1933 Act and the 1934 Act and the related published rules and regulations thereunder; (iii) based upon limited procedures set forth in detail in such letter (which shall include, without limitation, the procedures specified by the American Institute of Certified Public Accountants for a review of interim financial information as described in SAS No. 100, Interim Financial Information, with respect to the unaudited condensed consolidated financial statements of the Company and its subsidiaries included or incorporated by reference in the

Registration Statement), nothing came to their attention that caused them to believe that (1) any material modifications should be made to the unaudited financial statements and financial statement schedules of the Company and its subsidiaries included or incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus for them to be in conformity with accounting principles generally accepted in the United States, (2) the unaudited financial statements and financial statement schedules of the Company included or incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus do not comply as to form in all material respects with the applicable accounting requirements of the 1934 Act and the related published rules and regulations thereunder, or (3) at a specified date not more than three days prior to the date of such letter, there has been any change in the capital stock of the Company and the Operating Partnership or in the secured and unsecured debt of the Company and the Operating Partnership or any decrease in the total assets of the Company and the Operating Partnership, as compared with the amounts shown in the most recent consolidated balance sheet included or incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus or, during the period from the date of the most recent consolidated statement of operations included or incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus to a specified date not more than three days prior to the date of such letter, there were any decreases, as compared with the corresponding period in the preceding year, in rental income or in the total or per share amounts of net income or income before gains (losses) on investments, minority interests, discontinued operations and extraordinary items of the Company and the Operating Partnership, except in all instances for changes, increases or decreases which the Registration Statement, the General Disclosure Package and the Prospectus disclose have occurred or may occur or except for such exceptions enumerated in such letter as shall have been agreed to by the Agents and the Company and the Operating Partnership; (iv) they have compared the information in the Prospectus under selected captions with the disclosure requirements of Regulation S-K and on the basis of limited procedures specified in such letter nothing came to their attention as a result of the foregoing procedures that caused them to believe that this information does not conform in all material respects with the disclosure requirements of Items 301, 402 and 503(d) of Regulation S-K; and (v) in addition to the audit referred to in their opinions and the limited procedures referred to in clause (iii) and (iv) above, they have carried out certain specified procedures, not constituting an audit, with respect to certain amounts, percentages and financial information which are included or incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus and which are specified by the Agents, and have found such amounts, percentages and financial information to be in agreement with the relevant accounting, financial and other records of the Company and its subsidiaries identified in such letter; and (2) a letter from Ernst & Young LLP, dated as of the Settlement Date, in form and substance satisfactory to the Agents, to the effect that they reaffirm the statements made in the letter furnished by them pursuant to Section 7(d)(1) hereof, except that the specified date referred to therein for the carrying out of procedures shall be no more than three business days prior to such Settlement Date.

SECTION 8. Indemnification .

     (a)  Indemnification of the Agents . The Company and the Operating Partnership, jointly and severally, agree to indemnify and hold harmless each Agent and each person, if any, who controls such Agent within the meaning of Section 15 of the 1933 Act as follows:

     (i) against any and all loss, liability, claim, damage and expense whatsoever as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, in the Statutory Prospectus, the Prospectus, any preliminary prospectus, or in any amendment thereof or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the 1933 Act or arising out of or based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading;

     (ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission referred to in subsection (i) above, or any such alleged untrue statement or omission, if such settlement is effected with the written consent of the Company and the Operating Partnership; and

     (iii) against any and all expense whatsoever, as incurred (including, the fees and disbursements of counsel chosen by the Agents), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceedings by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided , however , that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company or the Operating Partnership by any Agent expressly for use in any such document referred to (i) above. This indemnity agreement will be in addition to any liability which the Company or the Operating Partnership may otherwise have.

     (b)  Indemnification of the Company . Each Agent severally and not jointly agrees to indemnify and hold harmless the Company and the Operating Partnership, the Company’s directors, each of the Company’s officers who signed the Registration Statement on behalf of the Company or the Operating Partnership and each person, if any, who controls the Company or the Operating Partnership within the meaning of Section 15 of the 1933 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, but only with respect to written information relating to such Agent furnished to the Company or the Operating Partnership by or on behalf of such Agent expressly for use in any document referred to in (a)(i) above. This indemnity agreement will be in addition to any liability which such Agent may otherwise have.

     (c)  Actions Against Parties; Notification . Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the

extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 8(a) hereof, counsel to the indemnified parties shall be selected by the applicable Agent(s) and, in the case of parties indemnified pursuant to Section 8(b) hereof, counsel to the indemnified shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided , however , that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances.

     No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 8 or 9 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

SECTION 9. Contribution .

     In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in Section 8 is for any reason held to be unenforceable by the indemnified parties although applicable in accordance with its terms, the Company and the Operating Partnership, on one hand, and the Agents, on the other, shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the Company and the Operating Partnership and one or more of the Agents, as incurred, in such proportions that each Agent is responsible for that portion represented by the percentage that the commission or underwriting discount received by such Agent bears to the total sales price from the sale of the Securities sold to or through such Agent that were the subject of the claim for indemnification and the Company and the Operating Partnership are responsible for the balance; provided, however, that no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 9, each person, if any, who controls an Agent within the meaning of Section 15 of the 1933 Act shall have the same rights to contribution as such Agent, and each director of the Company, each officer of the Company who signed the Registration Statement on behalf of the Company or the Operating Partnership, and each person, if any, who controls the Company or the Operating Partnership within the meaning of Section 15 of the 1933 Act shall have the same rights to contribution as the Company and the Operating Partnership.

     If the foregoing correctly sets forth our agreement, please indicate your acceptance hereof in the space provided for that purpose below. This action will confirm your appointment and your acceptance and agreement to act as Agent in connection with the issue and sale of the Securities under the terms and conditions of the Distribution Agreement.
