(each, a “Forward Seller” and, collectively, the “Forward Sellers”), acting severally and not jointly, of the respective numbers of an aggregate of 4,500,000 common shares of beneficial interest, par value $0.01 per share (the “Shares”) of the Company to be sold by them as set forth opposite their respective names under the column “Number of Forward Firm Shares to be Sold” appearing in the second table in Schedule A (the “Forward Firm Shares”) and the purchase by

the Underwriters, acting severally and not jointly, of the respective numbers of Forward Firm Shares to be purchased by each one of them from the Forward Sellers set forth opposite the names of the respective Underwriters appearing in the first table in Schedule A. The Forward Firm Shares and any Company Top-Up Firm Shares (as defined below) are collectively referred to as the “Firm Shares.”

In connection with the Forward Sale, Xxxxxx Xxxxxxx and Citibank, N.A., in their capacity as forward purchasers party to Forward Sale Agreements (as defined herein) (each, a “Forward Purchaser” and, collectively, the “Forward Purchasers”) have entered into letter agreements dated September 22, 2020 (the “Forward Sale Agreements”) with the Company, pursuant to which the Company has agreed to initially sell, and each Forward Purchaser has agreed to initially purchase, the number of Shares set forth opposite such Forward Purchaser’s name under the heading “Initial Number of Confirmation Shares to be Purchased” in Schedule A, subject to the terms and conditions of the Forward Sale Agreements, including the Company’s right to elect Cash Settlement or Net Share Settlement (each as defined in the Forward Sale Agreements).

In addition, the Forward Sellers have granted to the Underwriters an option to purchase all or any part of an aggregate of 675,000 Shares (the “Forward Optional Shares”) if and to the extent that the Representatives (as defined below) shall have determined to exercise, on behalf of the Underwriters, the right to purchase all or any part of such Forward Optional Shares pursuant to Section 2 hereof. The Forward Optional Shares and any Company Top-Up Optional Shares (as defined below) are collectively called the “Optional Shares.”

The Company Top-Up Firm Shares and the Company Top-Up Optional Shares are hereinafter collectively referred to as the “Company Shares.” The Forward Firm Shares and the Forward Optional Shares are herein referred to collectively as the “Forward Shares.” The Firm Shares and, if and to the extent such option is exercised, the Optional Shares are collectively called the “Offered Shares.” The Shares that the Company is or may be required to deliver in settlement of the Forward Sale Agreements are hereinafter sometimes called the “Confirmation Shares.” This Agreement and the Forward Sale Agreements are hereinafter collectively referred to as the “Transaction Documents.” Xxxxxx Xxxxxxx and Citigroup have agreed to act as representatives of the several Underwriters (in such capacity, the “Representatives”) in connection with the offering and sale of the Offered Shares.

Section 1. Representations and Warranties of the Company and the Operating Partnership.

Each of the Company and the Operating Partnership hereby represents, warrants and covenants to each Underwriter, Forward Seller and Forward Purchaser as of the date of this Agreement, as of the First Closing Date and as of each Option Closing Date (as hereinafter defined), if any, as follows:

(a) Compliance with Registration Requirements. The Registration Statement has become effective under the Securities Act. The Company has complied, to the Commission’s satisfaction with all requests of the Commission for additional or supplemental information, if any. No stop order suspending the effectiveness of the Registration Statement is in effect and no proceedings for such purpose have been instituted or are pending or, to the best knowledge of the Company, are contemplated or threatened by the Commission. At the time the Registration Statement was originally filed with the Commission, the Company met the then-applicable requirements for use of Form S-3 under the Securities Act. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the Time of Sale Prospectus and the Prospectus, at the time they were or hereafter are filed with the Commission, or became effective under the Exchange Act, as the case may be, complied and will comply at the time of such filing or effectiveness, as the case may be, in all material respects with the requirements of the Exchange Act.

(b) Disclosure.

Each of the Registration Statement and any post-effective amendment thereto, at the time it became or becomes effective, complied and will comply in all material respects with the Securities Act and did not and will not at the time of effectiveness, as

the case may be, contain any 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. As of the Applicable Time, the Time of Sale Prospectus did not, and at the First Closing Date (as defined in Section 2) and at each applicable Option Closing Date (as defined in Section 2), will not, contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Prospectus as of its date, did not, and at the First Closing Date and at each applicable Option Closing Date, will not, contain any untrue statement of a material fact or 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. The representations and warranties set forth in the three immediately preceding sentences do not apply to statements in or omissions from the Registration Statement or any post-effective amendment thereto, or the Prospectus or the Time of Sale Prospectus, or any amendments or supplements thereto, made in reliance upon and in conformity with written information relating to any Underwriter furnished to the Company in writing by or on behalf of the Representatives expressly for use therein, it being understood and agreed that the only such information consists of the information described in Section 9(b) below.

Each free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or that was prepared by or on behalf of or used or referred to by the Company complies or will comply in all material respects with the requirements of Rule 433 under the Securities Act, including timely filing with the Commission or retention where required and legending, and each such free writing prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Offered Shares did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, the Prospectus or any preliminary prospectus and not superseded or modified.

The supporting schedule included in the Registration Statement presents fairly the information required to be stated therein. The statements of revenues and certain expenses filed with the Commission as a part of the Registration Statement, the Time of Sale Prospectus and the Prospectus present fairly the revenues and certain expenses related to the operations of each of properties or group of properties identified in statements of revenues and certain expenses for the periods specified. Such financial statements and supporting schedule and statements of revenues and certain expenses have been prepared in conformity with generally accepted accounting principles (“GAAP”) applied on a consistent basis throughout the periods involved, except as may be expressly stated in the related notes thereto. The interactive data in eXtensible Business Reporting Language included or incorporated by reference in the Registration Statement fairly presents the information called for in all material respects and has been prepared in accordance with the Commission’s rules and guidelines applicable thereto.

To the Company’s knowledge, no person who has been suspended or barred from being associated with a registered public accounting firm, or who has failed to comply with any sanction pursuant to Rule 5300 promulgated by the PCAOB, has participated in or otherwise aided the preparation of, or audited, the financial statements, supporting schedules, statements of revenues and certain expenses or other financial data filed with the Commission as a part of the Registration Statement, the Time of Sale Prospectus and the Prospectus.

management’s general or specific authorization; (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences; and (v) the interactive data in eXtensible Business Reporting Language included or incorporated by reference in the Registration Statement, the Time of Sale Prospectus and the Prospectus fairly presents the information called for in all material respects and is prepared in accordance with the Commission’s rules and guidelines applicable thereto.

The Company has established and maintains disclosure controls and procedures (as defined in Rules 13a-15 and 15d-15 under the Exchange Act), which (i) are designed to ensure that material information relating to the Company, including its consolidated Subsidiaries, is made known to the Company’s principal executive officer and its principal financial officer by others within those entities, particularly during the periods in which the periodic reports required under the Exchange Act are being prepared; (ii) have been evaluated by management of the Company for effectiveness as of the end of the Company’s most recent fiscal quarter; and (iii) are effective in all material respects to perform the functions for which they were established. Since the end of the Company’s most recent audited fiscal year, there have been no significant deficiencies or material weakness in the Company’s internal control over financial reporting (whether or not remediated) and no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Neither the Company nor any Subsidiary is in violation of its declaration of trust, charter or bylaws, partnership agreement or operating agreement or similar organizational documents, as applicable, or is in default (or, with the giving of notice or lapse of time, would be in default) (“Default”) under any indenture, loan, credit agreement, note, lease, license agreement, contract, franchise or other instrument (including, without limitation, any pledge agreement, security agreement, mortgage or other instrument or agreement evidencing, guaranteeing, securing or relating to indebtedness) to which the Company or any Subsidiary is a party or by which it or any of them may be bound, or to which any of their respective properties or assets are subject (each, an “Existing Instrument”), except for such Defaults as would not be expected, individually or in the aggregate, to have a material adverse effect on the condition (financial or otherwise), earnings, business, properties, operations, assets, liabilities or prospects of the Company and the Subsidiaries, considered as one entity (a “Material Adverse Effect”). The Company’s and the Operating Partnership’s execution, delivery and performance of the Transaction Documents, consummation of the transactions contemplated hereby and thereby and by the Registration Statement, the Time of Sale Prospectus and the Prospectus and the issuance and sale of the Company Shares (including the use of proceeds from the sale of the Company Shares as described in the Registration Statement, the Time of Sale Prospectus and the Prospectus under the caption “Use of Proceeds”) (i) have been duly authorized by all necessary real estate investment trust or limited partnership action, as applicable, and will not result in any violation of the provisions of the declaration of trust or bylaws, partnership agreement, operating agreement or similar organizational documents, as applicable, of the Company or any Subsidiary; (ii) will not conflict with or constitute a breach of, or Default or a Debt Repayment Triggering Event (as hereinafter defined) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any Subsidiary pursuant to, or require the consent of any other party to (except for such consents as have been obtained or made by the Company or any such Subsidiary and are in full force and effect), any Existing Instrument, except as would not be expected, individually or in the aggregate, to have a Material Adverse Effect; and (iii) will not result in any violation of any law, administrative regulation or administrative or court decree applicable to the Company or any Subsidiary, except for such violations that would not be expected, individually or in the aggregate, to result in a Material Adverse Effect. No consent, approval, authorization or other order of, or registration or filing with, any court or other governmental or regulatory authority or agency (including, but not limited to, in connection with the Alternative Investment Fund Managers Directive 2011/61/EU (“AIFMD”) or any laws and regulations implementing AIFMD), is required for the Company’s or the Operating Partnership’s execution, delivery and performance of this Agreement and consummation of the transactions contemplated hereby and by the Registration Statement, the Time of Sale Prospectus and the Prospectus, except (i) such as have been obtained or made by the Company or the Operating Partnership and are in full force and effect under the Securities Act and (ii) such as may be required under applicable state securities or blue sky laws or by FINRA. As used herein, a “Debt Repayment Triggering Event” means any event or condition

which gives, or with the giving of notice or lapse of time would give, the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any Subsidiary.

(u) Compliance with Laws. The Company and the Subsidiaries have been and are in compliance with all applicable laws, rules and regulations, except where failure to be so in compliance would not be expected, individually or in the aggregate, to have a Material Adverse Effect.

(v) No Material Actions or Proceedings. There is no action, suit, proceeding, inquiry or investigation brought by or before any governmental entity now pending or, to the knowledge of the Company or the Operating Partnership, threatened, against or affecting the Company or any Subsidiary, which would be expected, individually or in the aggregate, to have a Material Adverse Effect or materially and adversely affect the consummation of the transactions contemplated by this Agreement or the performance by the Company or the Operating Partnership of its respective obligations hereunder; and the aggregate of all pending legal or governmental proceedings to which the Company or any Subsidiary is a party or of which any of their respective properties or assets is the subject, including ordinary routine litigation incidental to the business, if determined adversely to the Company or any Subsidiary, would not be expected to have a Material Adverse Effect. No material labor dispute with the employees of the Company or any Subsidiary exists or, to the knowledge of the Company and the Operating Partnership, is threatened or imminent, which, in either case, would, individually or in the aggregate, result in a Material Adverse Effect.

(w) Intellectual Property Rights. The Company and the Subsidiaries own or possess all inventions, patent applications, patents, trademarks (both registered and unregistered), trade names, service names, copyrights, trade secrets and other proprietary information described in the Registration Statement, the Time of Sale Prospectus or the Prospectus and as being owned or licensed by any of them or which is necessary for the conduct of, or material to, any of their respective businesses (collectively, the “Intellectual Property”), and the Company is unaware of any claim to the contrary or any challenge by any other person to the rights of the Company or any Subsidiary with respect to the Intellectual Property, which would be expected, individually or in the aggregate, to result in a Material Adverse Effect; neither the Company nor any Subsidiary has infringed or is infringing the intellectual property of a third party, which infringement would be expected, individually or in the aggregate, to result in a Material Adverse Effect, and neither the Company nor any Subsidiary has received notice of a claim by a third party to the contrary.

(x) All Necessary Permits, etc. The Company and the Subsidiaries possess such valid and current certificates, authorizations or permits required by state, federal or foreign regulatory agencies or bodies to conduct their respective businesses as currently conducted and as described in the Registration Statement, the Time of Sale Prospectus or the Prospectus (“Permits”). Neither the Company nor any Subsidiary is in violation of, or in default under, any

of the Permits or has received any notice of proceedings relating to the revocation or modification of, or non-compliance with, any such Permit.

(y) Title to Properties. (i) The Operating Partnership holds, directly or indirectly through another Subsidiary, good and marketable title (fee or, in the case of ground leases and as disclosed in the Registration Statement, the Time of Sale Prospectus and the Prospectus, leasehold) to all real property described in the Registration Statement, the Time of Sale Prospectus or the Prospectus as owned by it and the improvements located thereon (individually, a “Property,” and, collectively, the “Properties”), and the Company and the Subsidiaries have good and marketable title to all other assets, if any, owned by them, in each case, free and clear of all mortgages, deeds of trust, pledges, liens, security interests, claims, restrictions or encumbrances of any kind, except as (A) are described in the Registration Statement, the Time of Sale Prospectus and the Prospectus or (B) would not be expected, individually or in the aggregate, to result in a Material Adverse Effect; (ii) neither the Company nor any Subsidiary owns any real property other than the Properties that are described in the Registration Statement; (iii) (X) each ground lease relating to a Property under which the Company or a Subsidiary is a tenant is in full force and effect; (Y) neither the Company nor any Subsidiary has received any notice of any event which, with or without the passage of time or the giving of notice, or both, would constitute a material default under any such ground lease; and (Z) neither the Company nor any Subsidiary has received any notice of any material claim of any sort that has been asserted by anyone adverse to the rights of the Company or any Subsidiary under any such ground lease or affecting or questioning the rights of the Company or any Subsidiary to the continued possession of the leased premises under such ground lease; (iv) all liens, charges, encumbrances, claims or restrictions on any of the Properties or other assets of the Company or any Subsidiary that are required to be disclosed in the Registration Statement, the Time of Sale Prospectus and the Prospectus are disclosed therein; and (v) and no third party has any option or right of first refusal to purchase any Property or any portion thereof or interest therein (other than with respect to one Property that does not constitute a material portion of the Properties, taken as a whole).

Neither the Company nor the Operating Partnership has knowledge of any violation of any municipal, state or federal law, rule or regulation concerning any Property, except as would not be expected, individually or in the aggregate, to result in a Material Adverse Effect; each of the Properties complies with all applicable zoning laws, ordinances, regulations and deed restrictions or other covenants, except where the failure to comply would not be expected, individually or in the aggregate, to result in a Material Adverse Effect; neither the Company nor any Subsidiary has received from any governmental authority any written notice of any condemnation of or zoning change, and neither the Company nor any Subsidiary has received written notice of any such threatened condemnation or zoning change, that, in either case, if consummated, would not be expected, individually or in the aggregate, to have a Material Adverse Effect.

Except as disclosed in the Registration Statement, the Time of Sale Prospectus and the Prospectus, no mortgages encumbering the Properties are or will be: (i) convertible into an equity interest of the Company or any Subsidiary; (ii) cross-defaulted to any indebtedness other than

indebtedness of the Company or any Subsidiary; or (iii) cross-collateralized to any property or assets not owned directly or indirectly by the Company or any Subsidiary.

To the knowledge of the Company and the Operating Partnership, water, stormwater, sanitary sewer, electricity and telephone service are all available at the property lines of each Property over duly dedicated streets or perpetual easements of record benefiting the applicable Property, except as would not be expected, individually or in the aggregate, to result in a Material Adverse Effect.

(z) Tax Law Compliance. The Company and the Subsidiaries have filed all material federal, state and foreign income and franchise tax returns or have properly requested extensions thereof and have paid all material taxes required to be paid by any of them and, if due and payable, any related or similar material assessment, fine or penalty levied against any of them except as may be being contested in good faith and by appropriate proceedings. The Company has made adequate charges, accruals and reserves in the applicable financial statements referred to in Section 1(j) above in respect of all federal, state and foreign income and franchise taxes for all periods as to which the tax liability of the Company or any Subsidiary has not been finally determined. No material deficiency for taxes has been asserted against the Company or any Subsidiary, and there are no current, pending or threatened audits, assessments or other actions relating to any material tax liability of the Company or any Subsidiary.

(aa) Real Estate Investment Trust. Commencing with its taxable year ended December 31, 2015, the Company has been organized and operated in conformity with the requirements for qualification and taxation as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”), and the Company’s proposed method of operation will enable it to continue to meet the requirements for qualification and taxation as a REIT under the Code. All factual statements regarding the Company’s qualification and taxation as a REIT and descriptions of the Company’s organization and proposed method of operation set forth in the Registration Statement, the Time of Sale Prospectus and the Prospectus are true, complete and accurate in all material respects.

(bb) Insurance. Each of the Company and the Subsidiaries are insured by recognized, financially sound and reputable institutions with policies in such amounts and with such deductibles and covering such risks as are generally deemed adequate and customary for their businesses including, but not limited to, policies covering real and personal property owned or leased by the Company and the Subsidiaries against theft, damage, destruction, and acts of vandalism. Neither the Company nor the Operating Partnership has reason to believe that it or any Subsidiary will not be able (i) to renew its existing insurance coverage as and when such policies expire or (ii) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct its business as now conducted and at a cost that would not be expected to have a Material Adverse Effect. Neither the Company nor any Subsidiary has been denied any insurance coverage which it has sought or for which it has applied; provided that the representation in this sentence, as it relates to the DownREIT Partnerships, shall be to the knowledge of the Company.

(cc) Compliance with Environmental Laws. Except as would not be expected, individually or in the aggregate, to have a Material Adverse Effect: (i) neither the Company nor any Subsidiary is in violation of any federal, state, local or foreign statute, law, rule, regulation, ordinance, code, policy or rule of common law or any judicial or administrative interpretation thereof, including any judicial or administrative order, consent, decree or judgment, relating to pollution or protection of human health, the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including, without limitation, laws and regulations relating to the release or threatened release of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum or petroleum products (collectively, “Hazardous Materials”) or to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials (collectively, “Environmental Laws”); (ii) the Company and the Subsidiaries have all permits, authorizations and approvals required under any applicable Environmental Laws and are each in compliance with their requirements; (iii) there are no pending or threatened administrative, regulatory or judicial actions, suits, demands, demand letters, claims, liens, notices of noncompliance or violation, investigation or proceedings relating to any Environmental Law against the Company or any Subsidiary; and (iv) to the Company’s knowledge, there are no events or circumstances that might reasonably be expected to form the basis of an order for clean-up or remediation, or an action, suit or proceeding by any private party or governmental body or agency, against or affecting the Company or any Subsidiary relating to Hazardous Materials or any Environmental Laws.

(dd) ERISA Compliance. The Company and the Subsidiaries and any “employee benefit plan” (as defined under the Employee Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, “ERISA”)) established or maintained by the Company, the Subsidiaries or their “ERISA Affiliates” (as defined below) are in compliance in all material respects with ERISA. “ERISA Affiliate” means, with respect to the Company or any Subsidiary, any member of any group of organizations described in Sections 414(b), (c), (m) or (o) of the Internal Revenue Code of 1986, as amended, and the regulations and published interpretations thereunder (the “Code”) of which the Company or such Subsidiary is a member. No “reportable event” (as defined under ERISA) has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by the Company, the Subsidiaries or any of their ERISA Affiliates that are subject to Title IV of ERISA. No “employee benefit plan” subject to Title IV of ERISA established or maintained by the Company, the Subsidiaries or any of their ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit liabilities” (as defined under ERISA). Neither the Company, the Subsidiaries nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan” or (ii) Sections 412, 4971, 4975 or 4980B of the Code, other than as would not result in a Material Adverse Effect. Each employee benefit plan established or maintained by the Company, the Subsidiaries or any of their ERISA Affiliates that is intended to be qualified under Section 401(a) of the Code is so qualified and nothing has occurred, whether by action or failure to act, which would cause the loss of such qualification.

(ee) Company and Operating Partnership Not an “Investment Company.” Neither the Company nor the Operating Partnership is, or will be, either after receipt of payment for the Offered Shares or after the application of the proceeds therefrom as described under “Use of Proceeds” in the Registration Statement, the Time of Sale Prospectus or the Prospectus, required to register as an “investment company” under the Investment Company Act of 1940, as amended (the “Investment Company Act”).

(ff) No Price Stabilization or Manipulation; Compliance with Regulation M. Neither the Company nor any Subsidiary has taken, directly or indirectly, any action designed to or that might cause or result in stabilization or manipulation of the price of the Shares or of any “reference security” (as defined in Rule 100 of Regulation M under the Exchange Act (“Regulation M”)) with respect to the Shares, whether to facilitate the sale or resale of the Offered Shares or otherwise, and has taken no action which would directly or indirectly violate Regulation M.

Neither the Company nor any Subsidiary nor, to the best knowledge of the Company and the Operating Partnership, any employee or agent acting on behalf of the Company or any Subsidiary, in the course of its actions for, or on behalf of, the Company or any Subsidiary, has made any contribution or other payment to any official of, or candidate for, any federal, state or foreign office in violation of any law.

Neither the Company nor any Subsidiary nor, to the knowledge of the Company, any trustee, officer, agent, employee, affiliate or person acting on behalf of the Company or any Subsidiary is, or is controlled by a person or entity that is, (i) currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”), (ii) located, organized or resident in a country or territory that is the subject of sanctions (including, without limitation, Cuba, Iran, North Korea, Crimea, Sudan and Syria); neither the Company nor the Operating Partnership will directly or indirectly use the proceeds of this offering, or lend, contribute or otherwise make available such proceeds to any Subsidiary, or any joint venture partner or other person or entity, for the purpose of financing the activities of or business with any person, or in any country or territory, that currently is the subject to any U.S. sanctions administered by OFAC or in any other manner that will result in a violation by any person (including any person participating in the transaction whether as underwriter, advisor, investor or otherwise) of U.S. sanctions administered by OFAC. For the past five years, the Company and the Subsidiaries have not knowingly engaged in, are not now knowingly engaged in and will not engage in, any dealings or transactions with any person, or in any country or territory, that at the time of the dealing or transaction is or was the subject of sanctions.

No such statement was made with the knowledge of an executive officer or trustee of the Company that is was false or misleading.

(qq) Dividend Restrictions. Except as disclosed in the Registration Statement, the Time of Sale Prospectus and the Prospectus, or upon certain customary events of default under any mortgage or other loan document, no Subsidiary is prohibited or restricted, directly or indirectly, from paying dividends to the Company or the Operating Partnership, or from making any other distribution with respect to such Subsidiary’s equity securities or from repaying to the Company, the Operating Partnership or any other Subsidiary any amounts that may from time to time become due under any loans or advances to such Subsidiary from the Company or the Operating Partnership.

(rr) Credit Rating. Other than the Company's 6.000% Series A Cumulative Redeemable Preferred Shares of Beneficial Interest, par value $0.01 per share, and the Operating Partnership's senior unsecured notes due August 30, 2029, August 30, 2031, August 5, 2030 and August 5, 2032 respectively, neither the Company nor any Subsidiary has any debt securities or preferred stock that are rated by any “nationally recognized statistical rating agency” (as defined in Section 3(a)(62) of the Exchange Act).

Any certificate signed by any officer of the Company or any Subsidiary and delivered to any Underwriter, Forward Purchaser, Forward Seller or to counsel for the Underwriters and the Forward Purchasers and the Forward Sellers in connection with the offering, or the purchase and sale, of the Offered Shares shall be deemed a representation and warranty by the Company and the Operating Partnership to each Underwriter, Forward Purchaser and Forward Seller as to the matters covered thereby.

The Company and the Operating Partnership acknowledge that the Underwriters, the Forward Purchasers and the Forward Sellers and, for purposes of the opinions to be delivered pursuant to Section 6 hereof, counsel to the Company and the Operating Partnership and counsel to the Underwriters, the Forward Purchasers and the Forward Sellers, will rely upon the accuracy and truthfulness of the foregoing representations and hereby consents to such reliance.

Section 2. Purchase, Sale and Delivery of the Offered Shares.

(a) The Firm Shares. Upon the terms herein set forth, the Forward Sellers (with respect to the Forward Firm Shares) and the Company (with respect to any Company Top-Up Firm Shares), severally and not jointly, agree to issue and sell to the several Underwriters an aggregate of 4,500,000 Firm Shares. On the basis of the representations, warranties and agreements herein contained, and upon the terms but subject to the conditions herein set forth, the Underwriters agree, severally and not jointly, to purchase from the Forward Sellers (with respect to the Forward Firm Shares) and the Company (with respect to any Company Top-Up Firm Shares) the respective number of Firm Shares set forth opposite their names on Schedule A. The purchase price per Firm Share to be paid by the several Underwriters to the Forward Sellers (with respect to the Forward Firm Shares) or the Company (with respect to any Company Top-Up Firm Shares) shall be $32.832 per share. For the avoidance of doubt, the obligations of the Forward Sellers to sell Forward Shares under this Agreement are several and not joint. Each Forward Seller’s obligations extend solely to the number of Forward Firm Shares and the maximum number of Forward Optional Shares set forth opposite its name in the second table on Schedule A.

(b) The First Closing Date. Delivery of the Firm Shares to be purchased by the Underwriters and payment therefor shall be made at the New York offices of Xxxxxx & Xxxxxxx LLP (or such other place as may be agreed to by the Company and the Representatives) at 9:00 a.m. New York City time, on September 25, 2020, or such other time and date not later than 1:30 p.m. New York City time, September 25, 2020, as the Representatives shall designate by notice to the Company (the time and date of such closing are called the “First Closing Date”). Each of the Company and the Forward Sellers hereby acknowledges that circumstances under which the Representatives may provide notice to postpone the First Closing Date as originally scheduled include, but are not limited to, any determination by the Company or the Representatives to recirculate to the public copies of an amended or supplemented Prospectus, or a delay as contemplated by the provisions of Section 11 of this Agreement.

(c) The Optional Shares; Option Closing Date. In addition, on the basis of the representations, warranties and agreements herein contained, and upon the terms but subject to the conditions herein set forth, each Forward Seller (with respect to any Forward Optional Shares to be sold by such Forward Seller) and the Company (with respect to any Company Top-Up Optional Shares), severally and not jointly, hereby grants an option to the several Underwriters to purchase, severally and not jointly, up to the number of Forward Optional Shares set forth opposite the name of such Forward Seller under the caption "Maximum Number of

Forward Optional Shares to be Sold" in the second table on Schedule A, at the purchase price per share to be paid by the Underwriters for the Firm Shares; provided, however, that the amount paid by the Underwriters for any Optional Shares shall be reduced by an amount per share equal to any dividends declared by the Company and payable on the Firm Shares but not payable on such Optional Shares. The option granted hereunder may be exercised at any time and from time to time in whole or in part upon notice by the Representatives to the Forward Sellers and the Company, which notice may be given at any time within 30 days from the date of this Agreement. Such notice shall set forth (i) the aggregate number of Optional Shares as to which the Underwriters are exercising the option and (ii) the time, date and place at which the Optional Shares will be delivered (which time and date may be simultaneous with, but not earlier than, the First Closing Date; and in the event that such time and date are simultaneous with the First Closing Date, the term “First Closing Date” shall refer to the time and date of delivery of the Firm Shares and such Optional Shares). Any such time and date of delivery, if subsequent to the First Closing Date, is called an “Option Closing Date,” shall be determined by the Representatives and shall not be earlier than three or later than five full business days after delivery of such notice of exercise. If any Optional Shares are to be purchased, (i) each Underwriter agrees, severally and not jointly, to purchase the number of Optional Shares (subject to such adjustments to eliminate fractional shares as the Representatives may determine) that bears the same proportion to the total number of Optional Shares to be purchased as the number of Firm Shares set forth on Schedule A opposite the name of such Underwriter bears to the total number of Firm Shares bears to the total number of Optional Shares and (ii) each Forward Seller (with respect to any Forward Optional Shares) and the Company (with respect to any Company Top-Up Optional Shares), agrees, severally and not jointly, to sell (A) in the case of such Forward Seller, the number of Optional Shares that bears the same proportion to the total number of Optional Shares to be purchased as the number of Firm Shares set forth on Schedule A opposite the name of such Underwriter bears to the total number of Firm Shares bears to the total number of Optional Shares and (ii) in the case of the Company, the applicable number of Company Top-Up Optional Shares, if any (in each case subject to such adjustments to eliminate fractional shares as the Representatives may determine).

(d) The Representatives may cancel the option at any time prior to its expiration by giving written notice of such cancellation to the Company and the Forward Sellers.

(e) Public Offering of the Offered Shares. The Representatives hereby advise the Company that the Underwriters intend to offer for sale to the public, initially on the terms set forth in the Registration Statement, the Time of Sale Prospectus and the Prospectus, their respective portions of the Offered Shares as soon after this Agreement has been executed and the Registration Statement has been declared effective as the Representatives, in their sole judgment, have determined is advisable and practicable.

(f) Payment for the Offered Shares.

(i) Payment for the Offered Shares shall be made at the First Closing Date (and, if applicable, at each Option Closing Date) by wire transfer of immediately available

funds to the order of the Forward Sellers (with respect to any Forward Shares) or the Company (with respect to any Company Shares), as applicable.

(ii) It is understood that the Representatives have been authorized, for their own account and the accounts of the several Underwriters, to accept delivery of and receipt for, and make payment of the purchase price for, the Firm Shares and any Optional Shares the Underwriters have agreed to purchase. Each of Xxxxxx Xxxxxxx and Citigroup, individually and not as the Representatives of the Underwriters, may (but shall not be obligated to) make payment for any Offered Shares to be purchased by any Underwriter whose funds shall not have been received by the Representatives by the First Closing Date or the applicable Option Closing Date, as the case may be, for the account of such Underwriter, but any such payment shall not relieve such Underwriter from any of its obligations under this Agreement.

(g) Delivery of the Offered Shares. The Forward Sellers (with respect to the Forward Firm Shares) or the Company (with respect to any Company Top-Up Firm Shares), as applicable, shall deliver, or cause to be delivered the Firm Shares to the Representatives through the facilities of the Depository Trust Company (“DTC”) for the accounts of the several Underwriters at the First Closing Date, against release of a wire transfer of immediately available funds for the amount of the purchase price therefor. The Forward Sellers (with respect to any Forward Optional Shares) or the Company (with respect to any Company Top-Up Optional Shares) shall also deliver, or cause to be delivered the Optional Shares to the Representatives through the facilities of DTC for the accounts of the several Underwriters, at the First Closing Date or the applicable Option Closing Date, as the case may be, against the release of a wire transfer of immediately available funds for the amount of the purchase price therefor. The Offered Shares shall be registered in such names and denominations as the Representatives shall have requested at least two full business days prior to the First Closing Date (or the applicable Option Closing Date, as the case may be) and shall be made available for inspection on the business day preceding the First Closing Date (or the applicable Option Closing Date, as the case may be) at a location in New York City as the Representatives may designate. Time shall be of the essence, and delivery at the time and place specified in this Agreement is a further condition to the obligations of the Underwriters.

(h) Conditions to Borrow. If with respect to the Forward Shares (i) any of the conditions to effectiveness of a Forward Sale Agreement set forth therein have not been satisfied at the First Closing Date or the applicable Option Closing Date, as the case may be; (ii) the Company and the Operating Partnership have not performed all of their respective obligations required to be performed by them under this Agreement on or prior to the First Closing Date or the applicable Option Closing Date, as the case may be; or (iii) any of the conditions set forth in Section 6 hereof have not been satisfied on or prior to the First Closing Date or the applicable Option Closing Date, as the case may be (clauses (i) through (iii), together, the “Conditions”), each Forward Seller, in its sole discretion, may elect not to borrow and deliver for sale to the Underwriters the Forward Shares otherwise deliverable on such date by such Forward Seller hereunder. In addition, in the event that a Forward Purchaser determines in good faith, after using commercially reasonable efforts, that (A) it or its affiliate, as Forward Seller, is unable to borrow and deliver, on the First Closing Date or any Option Closing Date, as the case may be,

for sale under this Agreement a number of Shares equal to the number of Forward Shares otherwise deliverable on such date by such Forward Seller hereunder or (B) such Forward Seller would incur a stock loan cost of more than a rate equal to 25 basis points per annum to do so, then, in each case, such Forward Seller shall only be required to deliver for sale to the Underwriters on such date the aggregate number of Shares that such Forward Seller is able to so borrow at or below such cost.

The Company shall furnish to each Underwriter, Forward Purchaser and Forward Seller, without charge, as many copies of any free writing prospectus prepared by or on behalf of, used by or referred to by the Company as such Underwriter, Forward Purchaser and/or Forward Seller may reasonably request.

If the Time of Sale Prospectus is being used to solicit offers to buy the Offered Shares at a time when the Prospectus is not yet available to prospective purchasers, and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus so

that the Time of Sale Prospectus does not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances when delivered to a prospective purchaser, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement, or if, in the reasonable opinion of counsel for the Underwriters, the Forward Purchasers or the Forward Sellers, it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, the Company shall (subject to Section 3(b) and Section 3(c) hereof) promptly prepare, file with the Commission and furnish, at its own expense, to the Underwriters, the Forward Purchasers, the Forward Sellers and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances when delivered to a prospective purchaser, not misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the information contained in the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law.

(f) Certain Notifications and Required Actions. After the date of this Agreement and prior to the earlier of (A) the end of the 30 day period set forth in Section 2(c) and (B) the First Closing Date or the Option Closing Date, as the case may be, following the full exercise of the Underwriters’ option to purchase Optional Shares set forth in Section 2(c), the Registration Statement, the Time of Sale Prospectus and the Prospectus, the Company shall promptly advise the Representatives, the Forward Purchasers and the Forward Sellers in writing of: (i) the receipt of any comments of, or requests for additional or supplemental information from, the Commission; (ii) the time and date of any filing of any post-effective amendment to the Registration Statement or any amendment or supplement to any preliminary prospectus, the Time of Sale Prospectus, any free writing prospectus or the Prospectus; (iii) the time and date that any post-effective amendment to the Registration Statement becomes effective; and (iv) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto or any amendment or supplement to any preliminary prospectus, the Time of Sale Prospectus or the Prospectus or of any order preventing or suspending the use of any preliminary prospectus, the Time of Sale Prospectus, any free writing prospectus or the Prospectus, or of any proceedings to remove, suspend or terminate from listing or quotation the Shares from any securities exchange upon which they are listed for trading or included or designated for quotation, or of the threatening or initiation of any proceedings for any of such purposes. If the Commission shall enter any such stop order at any time, the Company will use its best efforts to obtain the lifting of such order at the earliest possible moment. Additionally, the Company agrees that it shall comply with all applicable provisions of Rule 424(b), Rule 433 and Rule 430A under the Securities Act and will use its reasonable efforts to confirm that any filings made by the Company under Rule 424(b) or Rule 433 were received in a timely manner by the Commission.

of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances when the Prospectus is delivered (whether physically or through compliance with Rule 172 under the Securities Act or any similar rule) to a purchaser, not misleading, or if in the reasonable opinion of the Representatives, the Forward Purchasers, the Forward Sellers or counsel for the Underwriters, the Forward Purchasers or the Forward Sellers it is otherwise necessary to amend or supplement the Prospectus to comply with applicable law, the Company agrees (subject to Section 3(b) and Section 3(c)) hereof to promptly prepare, file with the Commission and furnish, at its own expense, to the Underwriters, the Forward Purchasers, the Forward Sellers and to any dealer upon request, amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances when the Prospectus is delivered (whether physically or through compliance with Rule 172 under the Securities Act or any similar rule) to a purchaser, not misleading or so that the Prospectus, as amended or supplemented, will comply with applicable law. Neither the Representatives’ consent to, nor delivery of, any such amendment or supplement shall constitute a waiver of any of the Company’s obligations under Section 3(b) or Section 3(c).

(h) Blue Sky Compliance. The Company shall cooperate with the Representatives, the Forward Purchasers, the Forward Sellers and counsel for the Underwriters, the Forward Purchasers and the Forward Sellers to qualify or register the Offered Shares for sale under (or obtain exemptions from the application of) the state securities or blue sky laws or Canadian provincial securities laws (or other foreign laws) of those jurisdictions designated by the Representatives, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Offered Shares.

material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus, the Time of Sale Prospectus, any free writing prospectus that the Company has used, referred to or filed, or is required to file, pursuant to Rule 433(d) of the Securities Act, any Marketing Material or the Prospectus (or any amendment or supplement to the foregoing) or any prospectus wrapper material distributed in connection with the foregoing, or the omission or alleged omission to state therein a material fact necessary in order to make the statements, in the light of the circumstances under which they were made, not misleading; and to reimburse each Underwriter, Forward Purchaser, Forward Seller and each such affiliate, director, officer, employee, agent and controlling person for any and all expenses (including the fees and disbursements of counsel) as such expenses are incurred by such Underwriters, Forward Purchaser, Forward Seller or such affiliate, director, officer, employee, agent or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with information relating to any Underwriter, Forward Purchaser or Forward Seller furnished to the Company by the Representatives in writing expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any such free writing prospectus, any Marketing Material or the Prospectus (or any amendment or supplement thereto), it being understood and agreed that the only such information consists of the information described in Section 9(b) below. The indemnity agreement set forth in this Section 9(a) shall be in addition to any liabilities that the Company and the Operating Partnership may otherwise have.

(b) Indemnification of the Company and the Operating Partnership. Each Underwriter, Forward Purchaser and Forward Seller agrees, severally and not jointly, to indemnify and hold harmless the Company, the Operating Partnership, each of the Company’s trustees, each of its officers who signed the Registration Statement and each person, if any, who controls the Company or the Operating Partnership within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company, or any such trustee, officer or controlling person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Underwriter), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus, the Time of Sale Prospectus, any free writing prospectus, that the Company has used, referred to or filed, or is required to file, pursuant to Rule 433 of the Securities Act or the Prospectus (or any such amendment or supplement) or the omission or alleged omission to state therein a material fact necessary in order to make the statements, in the light of the circumstances under which they were made, not misleading, in each case to the

extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, such preliminary prospectus, the Time of Sale Prospectus, such free writing prospectus or the Prospectus (or any such amendment or supplement), in reliance upon and in conformity with information relating to such Underwriter, Forward Purchaser or Forward Seller, as applicable, furnished to the Company by the Representatives in writing expressly for use therein; and to reimburse the Company, the Operating Partnership, or any such trustee, officer or controlling person for any and all expenses (including the fees and disbursements of counsel) as such expenses are incurred by the Company, the Operating Partnership, or any such trustee, officer or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The Company and the Operating Partnership hereby acknowledge that the only information that the Representatives, the Forward Purchasers and the Forward Sellers have furnished to the Company expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) of the Securities Act or the Prospectus (or any amendment or supplement to the foregoing) are the statements set forth in paragraph 3 under the caption “Underwriting”, paragraph 1 under the caption “Underwriting—Underwriting Discounts and Expenses,” paragraphs 1 through 4 under the caption “Underwriting—Stabilization Transactions,” and “Underwriting—Electronic Distribution” in the Preliminary Prospectus Supplement and the Final Prospectus Supplement. The indemnity agreement set forth in this Section 9(b) shall be in addition to any liabilities that each Underwriter, Forward Purchaser or Forward Seller may otherwise have.

(c) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 9, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve the indemnifying party from any liability which it may have to any indemnified party to the extent the indemnifying party is not materially prejudiced (through the forfeiture of substantive rights and defenses) as a proximate result of such failure and shall not in any event relieve the indemnifying party from any liability that it may have otherwise than on account of this indemnity agreement. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, that if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action

on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 9 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the fees and expenses of more than one separate counsel (together with local counsel), representing the indemnified parties who are parties to such action), which counsel (together with any local counsel) for the indemnified parties shall be selected by the Representatives (in the case of counsel for the indemnified parties referred to in Section 9(a) above) or by the Company (in the case of counsel for the indemnified parties referred to in Section 9(b) above)) or (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action or (iii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party and shall be paid as they are incurred.

(d) Settlements. The indemnifying party under this Section 9 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 party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 9(c) hereof, the indemnifying party shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and does not include an admission of fault or culpability or a failure to act by or on behalf of such indemnified party.

Section 10. Contribution. If the indemnification provided for in Section 9 is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to

therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Operating Partnership, on the one hand, and the Underwriters, the Forward Purchasers and the Forward Sellers on the other hand, from the offering of the Offered Shares pursuant to this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Operating Partnership, on the one hand, and the Underwriters, the Forward Purchasers and the Forward Sellers, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Operating Partnership, on the one hand, and the Underwriters and the Forward Purchasers and the Forward Sellers, on the other hand, in connection with the offering of the Offered Shares pursuant to this Agreement shall be deemed to be in the same respective proportions as (X) in the case of the Company and the Operating Partnership, the total proceeds from the offering of the Offered Shares pursuant to this Agreement (before deducting expenses) received by the Company and the Operating Partnership (which total proceeds shall include the total proceeds that would be received by the Company pursuant to the Forward Sale Agreements assuming full Physical Settlement (as such term is defined in the Forward Sale Agreements) of the Forward Sale Agreements at the Initial Forward Price (as such term is defined in the Forward Sale Agreements), (Y) in the case of the Underwriters, the total underwriting discounts and commissions received by the Underwriters, and (Z) in the case of the Forward Purchasers and the Forward Sellers, the aggregate Spread (as defined in the Forward Sale Agreements) retained by the Forward Purchasers under the Forward Sale Agreements, net of any costs associated therewith, as reasonably determined by the Forward Purchasers, in each case as set forth in the Prospectus, bear to the sum of the amounts set forth in (X), (Y) and (Z) above. The relative fault of the Company and the Operating Partnership, on the one hand, and the Underwriters, the Forward Purchasers and the Forward Sellers, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Operating Partnership, on the one hand, or the Underwriters, the Forward Purchasers and the Forward Sellers, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 9(c), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 9(c) with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 10; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 9(c) for purposes of indemnification.

The Company, the Operating Partnership, the Underwriters, the Forward Purchasers and the Forward Sellers agree that it would not be just and equitable if contribution pursuant to this Section 10 were determined by pro rata allocation (even if the Underwriters, the Forward Sellers

and the Forward Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 10.

Notwithstanding the provisions of this Section 10, (i) no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions received by such Underwriter in connection with the Offered Shares underwritten by such Underwriter and distributed to the public and (ii) no Forward Seller shall be required to contribute any amount in excess of the amount by which the aggregate Spread (as defined in the applicable Forward Sale Agreement) retained by its affiliated Forward Purchaser under the applicable Forward Sale Agreement, net of any costs associated therewith, as reasonably determined by such Forward Seller, exceeds the aggregate amount of any damages that such Forward Seller and Forward Purchaser have otherwise been required to pay. 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 10 are several, and not joint, in proportion to their respective underwriting commitments as set forth opposite their respective names on Schedule A. The Forward Sellers' obligations to contribute pursuant to this Section 10 are several, and not joint, in proportion to their respective selling commitments as set forth opposite their respective names on Schedule A. For purposes of this Section 10, each affiliate, director, officer, employee and agent of an Underwriter, Forward Purchaser or Forward Seller and each person, if any, who controls an Underwriter, Forward Purchaser or Forward Seller within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as such Underwriter, Forward Purchaser or Forward Seller, as the case may be, and each trustee of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company or the Operating Partnership within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company and the Operating Partnership.

Section 11. Default of One or More of the Several Underwriters. If, on the First Closing Date or any Option Closing Date any of one or more of the several Underwriters shall fail or refuse to purchase Offered Shares that it or they have agreed to purchase hereunder on such date, and the aggregate number of Offered Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Offered Shares to be purchased on such date, the Representatives may make arrangements satisfactory to the Company for the purchase of such Offered Shares by other persons, including any of the Underwriters, but if no such arrangements are made by such date, the other Underwriters shall be obligated, severally and not jointly, in the proportions that the number of Firm Shares set forth opposite their respective names on Schedule A bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as may be specified by the Representatives with the consent of the non-defaulting Underwriters, to purchase the Offered Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the First Closing Date or any Option Closing Date any one or more of the Underwriters shall fail or refuse to purchase Offered Shares and the aggregate number of Offered Shares with

respect to which such default occurs exceeds 10% of the aggregate number of Offered Shares to be purchased on such date, and arrangements satisfactory to the Representatives, the Forward Purchasers, the Forward Sellers and the Company for the purchase of such Offered Shares are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Section 4, Section 7, Section 9 and Section 10 shall at all times be effective and shall survive such termination. In any such case either the Representatives, the Forward Purchasers, the Forward Sellers or the Company shall have the right to postpone the First Closing Date or the applicable Option Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Registration Statement and the Prospectus or any other documents or arrangements may be effected.

As used in this Agreement, the term “Underwriter” shall be deemed to include any person substituted for a defaulting Underwriter under this Section 11. Any action taken under this Section 11 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

Section 12. Termination of this Agreement. Prior to the purchase of the Firm Shares by the Underwriters on the First Closing Date, this Agreement may be terminated by the Representatives, the Forward Purchasers or the Forward Sellers by notice given to the Company if at any time: (i) trading or quotation in any of the Company’s securities shall have been suspended or limited by the Commission or by the NYSE, or trading in securities generally on either the NASDAQ or the NYSE shall have been suspended or limited, or minimum or maximum prices shall have been generally established on any of such stock exchanges; (ii) a general banking moratorium shall have been declared by any of federal, New York or Colorado authorities; (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in the judgment of the Representatives is material and adverse and makes it impracticable to market the Offered Shares in the manner and on the terms described in the Time of Sale Prospectus or the Prospectus or to enforce contracts for the sale of securities; (iv) in the judgment of the Representatives, the Forward Purchasers or the Forward Sellers, there shall have occurred any Material Adverse Change; or (v) the Company shall have sustained a loss by strike, fire, flood, earthquake, accident or other calamity of such character as in the judgment of the Representatives, Forward Purchasers or Forward Sellers may interfere materially with the conduct of the business and operations of the Company or the Operating Partnership regardless of whether or not such loss shall have been insured. Any termination pursuant to this Section 12 shall be without liability on the part of (a) the Company and the Operating Partnership to any Underwriter, Forward Purchaser or Forward Seller, except that the Company and the Operating Partnership shall be obligated to reimburse the expenses of the Representatives and the Underwriters pursuant to Section 4 or Section 7 hereof or (b) any Underwriter, Forward Purchaser or Forward Seller to the Company or the Operating Partnership; provided, however, that the provisions of Section 9 and Section 10 shall at all times be effective and shall survive such termination.

Section 13. (a) In the event that (i) a Forward Seller elects not to borrow Shares pursuant to the first sentence of Section 2(h) hereof, or (ii) a Forward Purchaser determines in good faith, after using commercially reasonable efforts, that (A) it or its affiliate, as Forward Seller, is unable to borrow and deliver, on the First Closing Date or any Option Closing Date, as the case may be, for sale under this Agreement a number of Shares equal to the number of Forward Shares otherwise deliverable on such date by such Forward Seller hereunder or (B) such Forward Seller would incur a stock loan cost of more than a rate equal to 25 basis points per annum to do so, then, in each case, upon notice by such Forward Seller to the Company and the Operating Partnership (which notice shall be delivered no later than 5:00 p.m., New York City time, on the business day immediately preceding the First Closing Date or such Option Closing Date, as the case may be), the Company shall issue and sell to the Underwriters, pursuant to Section 3 hereof, on the First Closing Date or such Option Closing Date, as the case may be, an aggregate number of Shares equal to the number of Forward Shares otherwise deliverable on such date by the applicable Forward Seller hereunder that such Forward Seller is not required to so deliver and sell to the Underwriters. In connection with any such issuance and sale by the Company, the Company or the Representatives shall have the right to postpone the First Closing Date or any Option Closing Date, as the case may be, for one business day in order to effect any required changes in any documents or arrangements. Any Shares sold by the Company to the Underwriters pursuant to this Section 13(a) in lieu of any Forward Firm Shares are referred to herein as the “Company Top-Up Firm Shares,” and (ii) any Shares sold by the Company to the Underwriters pursuant to this Section 13(a) in lieu of Forward Optional Shares are referred to herein as the “Company Top-Up Optional Shares.”

(b) A Forward Seller shall not have any liability whatsoever for any Forward Shares that such Forward Seller does not deliver and sell to the Underwriters or any other party if (i) all of the relevant Conditions are not satisfied on or prior to the First Closing Date or any Option Closing Date, as the case may be, and such Forward Seller validly elects pursuant to the first sentence of Section 2(h) hereof not to borrow and deliver and sell to the Underwriters the Forward Shares otherwise deliverable on such date by such Forward Seller hereunder, or (ii) the relevant Forward Purchaser determines in good faith, after using commercially reasonable efforts, that (A) it or its affiliate, as Forward Seller, is unable to borrow and deliver, on the First Closing Date or any Option Closing Date, as the case may be, for sale under this Agreement a number of Shares equal to the number of Forward Shares otherwise deliverable on such date by such Forward Seller hereunder or (B) such Forward Seller would incur a stock loan cost of more than a rate equal to 25 basis points per annum to do so (it being understood that the foregoing exclusion of liability shall not apply in the case of fraud and/or any intentional misconduct).

Section 14. No Advisory or Fiduciary Relationship. The Company and the Operating Partnership acknowledge and agree that (a) the purchase and sale of the Offered Shares pursuant to this Agreement, including the determination of the price of any Company Shares paid by the Underwriters to the Company, is an arm’s-length commercial transaction between the Company, on the one hand, and several Underwriters, Forward Sellers and Forward Purchasers, on the other hand, (b) in connection with the offering contemplated hereby and the process leading to such transaction, each Underwriter, Forward Purchaser and Forward Seller is and has been acting solely as a principal and is not the agent or fiduciary of the Company or the

Operating Partnership, or the Company’s other shareholders, creditors, employees or any other party, (c) no Underwriter, Forward Purchaser or Forward Seller has assumed or will assume an advisory or fiduciary responsibility in favor of the Company or the Operating Partnership with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter, Forward Purchaser or Forward Seller has advised or is currently advising the Company or the Operating Partnership on other matters) and no Underwriter, Forward Purchaser or Forward Seller has any obligation to the Company or the Operating Partnership with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, (d) the Underwriters, the Forward Purchasers, the Forward Sellers and each of their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and the Operating Partnership, (e) the Underwriters, the Forward Purchasers and the Forward Sellers have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company and the Operating Partnership have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate and (f) none of the activities of the Underwriters, the Forward Purchasers and the Forward Sellers in connection with the transactions contemplated herein constitutes a recommendation, investment advice, or solicitation of any action by the Underwriters the Forward Purchasers or the Forward Sellers with respect to any entity or natural person.

Section 15. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Company and the Operating Partnership, of their officers and of the several Underwriters, Forward Purchasers and Forward Sellers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriters, Forward Purchasers, Forward Sellers or the Company and the Operating Partnership or any of its or their partners, officers, trustees or directors or any controlling person, as the case may be, and, anything herein to the contrary notwithstanding, will survive delivery of and payment for the Offered Shares sold hereunder and any termination of this Agreement.

The term “successors” shall not

include any purchaser of the Offered Shares as such from any of the Underwriters merely by reason of such purchase.

Section 18. Partial Unenforceability. The invalidity or unenforceability of any section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other section, paragraph or provision hereof.

Section 19. Governing Law Provisions. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York applicable to agreements made and to be performed in such state.

Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum.

Section 20. General Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument and may be delivered by facsimile transmission or by electronic delivery of a portable document format (PDF) file. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The Article and Section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

The words “execution,” signed,” “signature,” and words of like import in this Agreement or in any other certificate, agreement or document related to this Agreement or the Shares shall include images of manually executed signatures transmitted by facsimile or other electronic format (including, without limitation, “pdf”, “tif” or “jpg”) and other electronic signatures (including, without limitation, DocuSign and AdobeSign). The use of electronic signatures and

electronic records (including, without limitation, any contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall be of the same legal effect, validity and enforceability as a manually executed signature or use of a paper-based recordkeeping system to the fullest extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act and any other applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act or the Uniform Commercial Code.

Each of the parties hereto acknowledges that it is a sophisticated business person who was adequately represented by counsel during negotiations regarding the provisions hereof, including, without limitation, the indemnification provisions of Section 9 and the contribution provisions of Section 10, and is fully informed regarding said provisions. Each of the parties hereto further acknowledges that the provisions of Section 9 and Section 10 hereof fairly allocate the risks in light of the ability of the parties to investigate the Company, its affairs and its business in order to assure that adequate disclosure has been made in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, each free writing prospectus and the Prospectus (and any amendments and supplements to the foregoing), as contemplated by the Securities Act and the Exchange Act.

Section 21. Recognition of the U.S. Special Resolution Regimes.

RE: National Storage Affiliates Trust (the “Company”)

Ladies & Gentlemen:

The undersigned is an owner of common shares of beneficial interest, par value $0.01 per share, of the Company (“Shares”) or of securities convertible into or exchangeable or exercisable for Shares. The Company proposes to conduct a public offering of Shares (the “Offering”) for which Xxxxxx Xxxxxxx & Co. LLC (“Xxxxxx Xxxxxxx”) and Citigroup Global Markets Inc. (“Citigroup”) will act as the representatives of the underwriters. The undersigned recognizes that the Offering will benefit each of the Company, NSA OP, LP (the “Operating Partnership”) and the undersigned. The undersigned acknowledges that the Underwriters are relying on the representations and agreements of the undersigned contained in this letter agreement in conducting the Offering and, at a subsequent date, in entering into an underwriting agreement (the “Underwriting Agreement”) and other underwriting arrangements with the Company and the Operating Partnership with respect to the Offering.

Annex A sets forth definitions for capitalized terms used in this letter agreement that are not defined in the body of this agreement. Those definitions are a part of this agreement.

In consideration of the foregoing, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned hereby agrees that, during the Lock-up Period, the undersigned will not (and will cause any Family Member not to), without the prior written consent of Xxxxxx Xxxxxxx and Citigroup, which may withhold their consent in their sole discretion:

i. Sell or Offer to Sell any Shares or Related Securities currently or hereafter owned either of record or beneficially (as defined in Rule 13d-3 under the Exchange Act) by the undersigned or such Family Member,

ii. enter into any Swap,

iii. make any demand for, or exercise any right with respect to, the registration under the Securities Act of the offer and sale of any Shares or

Related Securities, or cause to be filed a registration statement, prospectus or prospectus supplement (or an amendment or supplement thereto) with respect to any such registration, or

iv. publicly announce any intention to do any of the foregoing.

The foregoing will not apply to the registration of the offer and sale of the Shares, and the sale of the Shares to the underwriters, in each case as contemplated by the Underwriting Agreement. In addition, the foregoing restrictions shall not apply to the transfer of Shares or Related Securities (A) by bona fide gift or gifts, (B) by will or intestate succession to a Family Member, (C) to a trust whose beneficiaries consist exclusively of one or more of the undersigned and/or a Family Member, (D) as a distribution to limited partners, members, shareholders or other equity holders of an entity controlled by the undersigned, (E) to the Company to satisfy tax withholding obligations (including estimated tax withholding obligations) incurred by the undersigned as a result of the exercise of any option to purchase Shares or in connection with the vesting of restricted share awards issued pursuant to the Company’s 2015 Equity Incentive Plan, (F) in connection with a conversion of Class A OP Units into Class B OP Units and LTIP Units into Class A OP Units in accordance with, and as defined by, the limited partnership agreement of the Operating Partnership, (G) constituting a pledge, hypothecation or grant of a security interest to a qualified financial institution that has been initiated, but not finalized, prior to the date hereof, (H) with respect to Shares or Related Securities that have been pledged or hypothecated or for which a security interest has been granted to a qualified financial institution prior to the date hereof, any transfer in connection with the enforcement of, or foreclosure upon, such Shares or Related Securities by such qualified financial institution; (I) in connection with a conversion of Class B OP Units into Class A OP Units in accordance with, and as defined by, the limited partnership agreement of the Operating Partnership; provided, however, that in the case of clause (A), (B), (C), (D), (F), (G), (H) or (I) above, it shall be a condition to such transfer that:

· each transferee executes and delivers to Xxxxxx Xxxxxxx and Citigroup an agreement in form and substance reasonably satisfactory to Xxxxxx Xxxxxxx and Citigroup stating that such transferee is receiving and holding such Shares and/or Related Securities subject to the provisions of this letter agreement and agrees not to Sell or Offer to Sell such Shares and/or Related Securities, engage in any Swap or engage in any other activities restricted under this letter agreement except in accordance with this letter agreement (as if such transferee had been an original signatory hereto), and

in the case of clause (A), (C), (D), (E), (G) or (I) above, it shall be a condition to such transfer that:

· prior to the expiration of the Lock-up Period, no public disclosure or filing under the Exchange Act by any party to the transfer (donor, donee, transferor or transferee) shall be required, or made voluntarily, reporting a reduction in beneficial ownership of Shares in connection with such transfer (or, in the case of clause (G), in connection with any subsequent foreclosure on the Shares or Related Securities subject to such security interest by the transferee).

Furthermore, the undersigned may transfer Common Shares of the Company purchased by the undersigned on the open market following the Public Offering, without the prior written consent of Xxxxxx Xxxxxxx and Citigroup, if and only if prior to the expiration of the Lock-up Period, no public disclosure or filing under the Exchange Act by any party to the transfer shall be required, or made voluntarily, reporting a reduction in beneficial ownership of Shares in connection with such transfer.

The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of Shares or Related Securities held by the undersigned and the undersigned’s Family Members, if any, except in compliance with the foregoing restrictions.

With respect to the Offering only, the undersigned waives any registration rights relating to registration under the Securities Act of the offer and sale of any Shares and/or any Related Securities owned either of record or beneficially by the undersigned, including any rights to receive notice of the Offering.

The undersigned confirms that the undersigned has not, and has no knowledge that any Family Member has, directly or indirectly, taken any action designed to or that might reasonably be expected to cause or result in the stabilization or manipulation of the price of any security of the Company to facilitate the sale of the Shares. The undersigned will not, and will cause any Family Member not to take, directly or indirectly, any such action.

Whether or not the Offering occurs as currently contemplated or at all depends on market conditions and other factors. The Offering will only be made pursuant to the Underwriting Agreement, the terms of which are subject to negotiation between the Company, the Operating Partnership and the underwriters.

The undersigned understands that, if the Underwriting Agreement does not become effective by September 22, 2020, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Shares to be sold thereunder, the undersigned shall be released from all obligations under this letter agreement automatically and without any action on the part of Xxxxxx Xxxxxxx and Citigroup.

The undersigned hereby represents and warrants that the undersigned has full power, capacity and authority to enter into this letter agreement. This letter agreement is irrevocable and will be binding on the undersigned and the successors, heirs, personal representatives and assigns of the undersigned.

This letter agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to the conflict of law principles thereof.
