As Representatives of the several Underwriters listed in Schedule 1 hereto

Ladies and Gentlemen:

Mid-America Apartments, L.P., a Tennessee limited partnership (the “Operating Partnership”) and majority owned subsidiary of Mid-America Apartment Communities, Inc., a Tennessee corporation (the “Company”), proposes to issue and sell to the several Underwriters listed in Schedule 1 hereto (the “Underwriters”), for whom you are acting as representatives (the “Representatives”), $600,000,000 aggregate principal amount of the Operating Partnership’s 3.600% Senior Notes due 2027 (the “Securities”). The Securities will be issued pursuant to the Indenture to be dated as of May 9, 2017 (the “Base Indenture”), as amended and supplemented by a First Supplemental Indenture to be dated as of May 9, 2017 (the “Supplemental Indenture;” the Base Indenture, as amended and supplemented by the Supplemental Indenture, is hereinafter called the “Indenture”), each between the Operating Partnership and U.S. Bank National Association, as trustee (the “Trustee”).

As used herein, the term “Transaction Documents” means this underwriting agreement (this “Agreement”), the Securities, the Base Indenture and the Supplemental Indenture.

The Operating Partnership hereby confirms its agreement with the several Underwriters concerning the purchase and sale of the Securities, as follows:

1. Registration Statement. The Operating Partnership and the Company have prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration statement on Form S-3 (File Nos. 333-208398 and 333-208398-01), including a prospectus, relating to the Securities, which registration became effective upon filing under Rule 462(e) of the Securities Act. Such registration statement, as amended at each time of effectiveness under the Securities Act, including the information deemed pursuant to Rule 430B under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary Prospectus” means each prospectus included in such registration statement (and any amendments thereto) before it became effective, any prospectus or prospectus supplement filed with the Commission pursuant to Rule 424(b) under the Securities Act that relates to the offering of the Securities, the prospectus and any prospectus supplement included in the Registration Statement at the time of its effectiveness that omits Rule 430 Information and the Time of Sale Prospectus (as defined below), and the term “Prospectus” means the prospectus supplement dated May 2, 2017 (the “Prospectus Supplement”), together with the accompanying prospectus dated December 9, 2015 (the “Base Prospectus”), in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Securities. Any reference in this Agreement to the Registration Statement, the Base Prospectus, any Preliminary Prospectus (including, without limitation, the Time of Sale Prospectus) or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, as of the effective date of the Registration Statement or the date of the Base Prospectus, such Preliminary Prospectus or the Prospectus, as the case may be, and any reference to “amend”, “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include (a) in the case of the Registration Statement, any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”) that are deemed to be incorporated by reference therein and (b) in the case of the Base Prospectus, any Preliminary Prospectus and the Prospectus, any documents filed after the date of the Base Prospectus, such Preliminary Prospectus or the Prospectus, respectively, under the Exchange Act that are deemed to be incorporated by reference therein. As used in this Agreement, references to the date of any Preliminary Prospectus or Prospectus that consists of a prospectus supplement and accompanying prospectus mean the date of such prospectus supplement. References in this Agreement to financial statements or other information that is “contained,” “included,” “described,” “set forth” or “provided” in the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Prospectus and similar references shall, unless stated otherwise, include any information incorporated or deemed to be incorporated by reference therein; and references in this Agreement to “subsidiaries” or any “subsidiary” of the Company shall include, without limitation, the Operating Partnership. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Time of Sale Prospectus.

At or prior to 2:40 p.m. (New York time) on May 2, 2017, the time when sales of the Securities were first made (the “Time of Sale”), the Operating Partnership had prepared the following information (collectively, the “Time of Sale Information”): a preliminary prospectus supplement dated May 2, 2017 (the “Preliminary Prospectus Supplement”) and accompanying Base Prospectus (such documents, in the form first made available to the Underwriters for use in the offering of the Securities, are hereinafter called, collectively, the “Time of Sale Prospectus”), and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex A hereto.

2. Purchase of the Securities by the Underwriters.

(a) The Operating Partnership agrees to issue and sell the Securities to the several Underwriters as provided in this Agreement, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the Operating Partnership the respective principal amount of Securities set forth opposite such Underwriter’s name in Schedule 1 hereto at a price equal to 98.930% of the principal amount thereof. The Operating Partnership will not be obligated to deliver any of the Securities except upon payment for all the Securities to be purchased as provided herein.

(b) The Operating Partnership understands that the Underwriters intend to make a public offering of the Securities as soon after the effectiveness of this Agreement as in the judgment of the Representatives is advisable, and initially to offer the Securities on the terms set forth in the Time of Sale Information. The Operating Partnership acknowledges and agrees that the Underwriters may offer and sell Securities to or through any affiliate of an Underwriter and that any such affiliate may offer and sell Securities purchased by it to or through any Underwriter.

(c) Payment for and delivery of the Securities will be made at the offices of Sidley Austin LLP, ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇ at 10:00 a.m., New York City time, on May 9, 2017, or at such other time or place on the same or such other date, not later than the fifth business day thereafter, as the Representatives and the Operating Partnership may agree upon in writing.

The Global Note will be made available for inspection by the Representatives not later than 1:00 p.m., New York City time, on the business day prior to the Closing Date.

(e) The Operating Partnership acknowledges and agrees that each Underwriter is acting solely in the capacity of an arm’s length contractual counterparty to the Operating Partnership with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Operating Partnership or any other person. Additionally, neither the Representatives nor any other Underwriter is advising the Operating Partnership or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Operating Partnership shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and neither the Representatives nor any other Underwriter shall have any responsibility or liability to the Operating Partnership with respect thereto. Any review by the Representatives or any Underwriter of the Operating Partnership, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Representatives or such Underwriter and shall not be on behalf of the Operating Partnership or any other person.

3. Representations and Warranties of the Operating Partnership. The Operating Partnership represents and warrants to, and agrees with, each Underwriter that:

(a) Preliminary Prospectus. No order preventing or suspending the use of any Preliminary Prospectus has been issued by the Commission, and each Preliminary Prospectus, at the time of filing thereof, complied in all material respects with the Securities Act and did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that the Operating Partnership makes no representation or warranty with respect to any statements or omissions made in reliance upon and in conformity with information relating to any Underwriter furnished to the Operating Partnership in writing by such Underwriter through the Representatives expressly for use in any Preliminary Prospectus.

The Company has been duly incorporated and is validly existing and in good standing under the laws of the State of Tennessee, with all power and authority to own, lease and operate its properties and conduct its business as described in the Registration Statement, the Prospectus and the Time of Sale Information. The Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not reasonably be expected to result in a Material Adverse Effect (as defined below). The Company is the sole general partner of the Operating Partnership and the Company owns the percentage of the outstanding equity interests in the Operating Partnership disclosed in the Registration Statement, the Time of Sale Information and the Prospectus. As used herein, “Material Adverse Effect” means a material adverse effect on the properties, financial condition, results of operations or business affairs of the Company and its subsidiaries considered as one enterprise or of the Operating Partnership and its subsidiaries considered as one enterprise; for purposes of clarity, it is hereby understood and agreed that statements to the effect that certain matters will not or could not reasonably be expected to have or result in a Material Adverse Effect (and statements of like effect) mean that such matters will not have a Material Adverse Effect on the Company or on the Operating Partnership.

The Operating Partnership has been duly organized and is validly existing as a limited partnership and in good standing under the laws of the State of Tennessee and has limited partnership power and authority to own, lease and operate its properties and to conduct its business as described in the Registration Statement, the Prospectus and the Time of Sale Information. The Operating Partnership is duly qualified as a foreign entity to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not reasonably be expected to result in a Material Adverse Effect. Each Significant Subsidiary (as defined below) of the Company in addition to the Operating Partnership has been duly organized and is validly existing and in good standing under the laws of the jurisdiction of its organization, has power and authority to own, lease and operate its properties and to conduct its business as described in the Registration Statement, the Prospectus and the Time of Sale Information and is duly qualified to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not reasonably be expected to result in a Material Adverse Effect. All of the issued and outstanding shares of capital stock, limited liability company interests, partnership interests or other equity interests, as the case may be, of each such Significant Subsidiary (i) have been duly authorized and validly issued, are fully paid and non-assessable and (ii) except for the Operating Partnership or as otherwise disclosed in the Registration Statement, the Prospectus and the Time of Sale Information, are owned by the Company, directly or through subsidiaries, free and clear of any security interest, mortgage, pledge, lien, encumbrance, claim or equity; no outstanding shares of capital stock, limited liability company interests, partnership interests or other equity interests, as the case may be, of any Significant Subsidiary were issued in violation of the preemptive or similar rights of any security holder of such Significant Subsidiary. As used in this Agreement, the term “Significant Subsidiary” means each subsidiary of the Company that would be deemed a “Significant Subsidiary” of the Company under either clause (1) or (2) of the definition of “significant subsidiary” appearing in Rule 1-02 of Regulation S-X.

(l) Partnership Capitalization. Without limitation to any other representations and warranties set forth herein, all of the outstanding partnership interests of the Operating Partnership have been duly authorized and validly issued and the capital contributions with respect thereto have been made in full; and the partnership interests of the Operating Partnership that are owned, directly or indirectly, by the Company are owned in the percentage set forth in the Registration Statement, the Prospectus and the Time of Sale Information, free and clear (except as may otherwise be specifically described in the Registration Statement, the Prospectus and the Time of Sale Information) of any lien, charge, encumbrance, security interest, restriction on voting or transfer or any other claim of any third party.

None of the outstanding partnership interests of the Operating Partnership were issued in violation of the preemptive or other rights of the security holders of the Operating Partnership.

(m) Due Authorization. The Operating Partnership has full right, power and authority to execute and deliver the Transaction Documents and to perform its obligations thereunder, including, without limitation, the issuance, sale and delivery of the Securities, as contemplated by this Agreement and the Indenture; and all action required to be taken for the due and proper authorization, execution and delivery by the Operating Partnership of the Transaction Documents and the consummation by it of the transactions contemplated thereby has been duly and validly taken.

(p) Description of Transaction Documents. Each of the Transaction Documents conforms in all material respects to the descriptions thereof contained in the Registration Statement, the Prospectus and the Time of Sale Information.

(q) Indenture. Each of the Base Indenture and the Supplemental Indenture has been duly authorized by the Operating Partnership and, prior to the delivery and payment for the Securities on the Closing Date, will have been duly executed and delivered by the Operating Partnership and will constitute a valid and legally binding agreement of the Operating Partnership, enforceable against the Operating Partnership in accordance with its terms, subject to the Enforceability Exceptions; and the Indenture has been duly qualified under the Trust Indenture Act.

(r) Securities. The Securities have been duly authorized by the Operating Partnership and, when duly authenticated, issued and delivered as provided in the Indenture and paid for as provided herein, will have been duly executed and delivered by the Operating Partnership, will be duly and validly issued and outstanding and will constitute valid and legally binding obligations of the Operating Partnership, enforceable against the Operating Partnership in accordance with their terms, subject to the Enforceability Exceptions, and will be entitled to the benefits of the Indenture.

(s) No Violation or Default. Neither the Company nor any of its subsidiaries is (i) in violation of its charter or by-laws, partnership agreement, limited liability company agreement or other Organizational Documents (as defined below), (ii) in default, and no event has occurred that, with notice or lapse of time or both, would constitute such a default, in the due performance or observance of any term, covenant or condition contained in any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which the Company or any of its subsidiaries is bound or to which any of the property or assets of the Company or any of its subsidiaries is subject, or (iii) in violation of any law or statute or any judgment, order, rule or regulation of any court or arbitrator or governmental or regulatory authority, except, in the case of clauses (ii) and (iii) above, for any such default or violation that would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

The execution, delivery and performance by the Operating Partnership of the Transaction Documents, the issuance and sale of the Securities, the compliance by the Operating Partnership with the terms of the Transaction Documents and the consummation of the transactions contemplated by the Transaction Documents will not (i) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which the Company or any of its subsidiaries is bound or to which any of the property or assets of the Company or any of its subsidiaries is subject, (ii) result in any violation of the provisions of the charter or bylaws of the Company, the Operating Partnership’s certificate of limited partnership or Partnership Agreement or the Organizational Documents of any of the Company’s other subsidiaries or (iii) result in the violation of any law or statute or any judgment, order, rule or regulation of any court or arbitrator or governmental or regulatory authority, except, in the case of clauses (i) and (iii) above, for any such conflicts, breaches, violations or defaults that would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect or to adversely affect the consummation of the transactions contemplated by the Transaction Documents or the performance by the Operating Partnership of its obligations under the Transaction Documents; and no consent, approval, authorization, order, registration or qualification of or with any court or governmental agency or body is required for the execution, delivery and performance by the Operating Partnership of the Transaction Documents, the issuance and sale of the Securities, compliance by the Operating Partnership with the terms of the Transaction Documents or the consummation of the transactions contemplated by the Transaction Documents, except as have been made or obtained under the Securities Act and the Exchange Act and except as may be required by and made in accordance with or obtained under state securities laws or regulations.

(a) Indemnification of the Underwriters. The Operating Partnership agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable out of pocket legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto) or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus, any Issuer Free Writing Prospectus or any Time of Sale Information (or any amendment or supplement to any of the foregoing) or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Operating Partnership in writing by such Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in paragraph (b) below.

(b) Indemnification of the Operating Partnership. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Operating Partnership, any director or officer of the Company acting in its capacity as general partner of the Operating Partnership who signed the Registration Statement and each person, if any, who controls the Operating Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Operating Partnership in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or any Time of Sale Information (or any amendment or supplement to any of the foregoing), it being understood and agreed that the only such information consists of the following paragraphs in the Time of Sale Prospectus and the Prospectus: (i) the first full paragraph under the subcaption “Underwriting (conflicts of interest)—Commissions and discounts” concerning the public offering price, concession and reallowance; (ii) the third sentence under the subcaption “Underwriting (conflicts of interest)—No prior market for the notes” concerning market-making; and (iii) the paragraph under the subcaption “Underwriting (conflicts of interest)—Price stabilization and short positions” but only insofar as concerns the Underwriters, regarding stabilization, overallotments and short positions.

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. Subject to the proviso to this sentence, the Indemnifying Person shall be entitled to participate in the defense of any claim, and to the extent that it may wish, assume the defense thereof with counsel reasonably satisfactory to the Indemnified Person; provided, however, that in any such proceeding, any Indemnified Person shall have the right to retain its own counsel (in which case the Indemnifying Person shall not be entitled to participate in or assume the defense of any suit, action, proceeding, investigation, claim or demand brought or asserted against such Indemnified Person), but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in

writing by the Representatives and any such separate firm for the Operating Partnership, any director or officer of the Company acting in its capacity as general partner of the Operating Partnership who signed the Registration Statement and any control persons of the Operating Partnership shall be designated in writing by the Operating Partnership. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification has been or could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraph (a) or (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Operating Partnership on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Operating Partnership on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Operating Partnership on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Operating Partnership from the sale of the Securities and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Securities. The relative fault of the Operating Partnership on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Operating Partnership or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Operating Partnership and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any reasonable legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an

Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

8. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

9. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Operating Partnership, if after the execution and delivery of this Agreement and on or prior to the Closing Date (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange or the over-the-counter market; (ii) trading of any securities issued or guaranteed by the Operating Partnership or the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

10. Defaulting Underwriter.

(a) If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Operating Partnership on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Operating Partnership shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters or the Operating Partnership may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Operating Partnership or counsel for the Underwriters may be necessary in the Registration Statement, the Time of Sale Information and the Prospectus or in any other document or arrangement, and the Operating Partnership agrees to promptly prepare any amendment or supplement to the Registration Statement, the Time of Sale Information and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and by other persons satisfactory to the Operating Partnership as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Operating Partnership shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the principal amount of Securities that such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and by other persons satisfactory to the Operating Partnership as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Operating Partnership shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Operating Partnership, except that the Operating Partnership will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Operating Partnership, the Company or any non-defaulting Underwriter for damages caused by its default.

11. Payment of Expenses.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Operating Partnership agrees to pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in connection therewith; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, each Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Operating Partnership’s counsel and of Ernst & Young LLP and Deloitte & Touche LLP; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representatives may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related and reasonable fees and expenses of counsel for the Underwriters); (vi) any fees charged by rating agencies for rating the Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (viii) all expenses (including reasonable fees and expenses of counsel for the Underwriters) and application fees incurred in connection with any filing with, and clearance of the offering by, the Financial Industry Regulatory Authority, and all expenses and application fees incurred in connection with the approval of the Securities for book-entry transfer by DTC; and (ix) all expenses incurred by the Operating Partnership in connection with any “road show” presentation to potential investors.

(b) If (i) this Agreement is terminated pursuant to Section 9, (ii) the Operating Partnership for any reason fails to tender the Securities for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Securities for any reason permitted under this Agreement, the Operating Partnership agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

12. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein, and the affiliates of each Underwriter referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

13. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Operating Partnership and the Underwriters contained in this Agreement or made by or on behalf of the Operating Partnership or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Operating Partnership or the Underwriters.

14. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; and (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act.

15. Compliance with USA Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Operating Partnership and the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.
