ARTICLE II

ISSUANCE AND SALE OF COMMON SHARES

Section 2.01 Issuance.

(a) Upon the terms and subject to the conditions of this Agreement, EQR may issue Program Shares through JPMorgan and JPMorgan shall use its commercially reasonable efforts to sell Program Shares, up to the Maximum Program Amount, based on and in accordance with such number of Issuance Notices as EQR in its sole discretion shall choose to deliver during the Commitment Period until the number of the Program Shares sold under the Sales Agency Agreements equals the Maximum Program Amount or this Agreement is otherwise terminated. Subject to the foregoing and the other terms and conditions of this Agreement, upon the delivery of an Issuance Notice, and unless the sale of the Issuance Shares described therein has been suspended, cancelled or otherwise terminated in accordance with the terms of this Agreement, JPMorgan will use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such Issuance Shares up to the amount specified into the Principal Market, and otherwise in accordance with the terms of such Issuance Notice. JPMorgan will provide written confirmation to EQR no later than the opening of the Trading Day next following the Trading Day on which it has made sales of Issuance Shares hereunder setting forth the portion of the Actual Sold Amount for such Trading Day, the corresponding Sales Price and the Issuance Price payable to EQR in respect thereof. JPMorgan may sell Issuance Shares in the manner described in Section 2.01(b) herein. Each of the Transaction

Entities acknowledges and agrees that (i) there can be no assurance that JPMorgan will be successful in selling Issuance Shares and (ii) JPMorgan will incur no liability or obligation to the Transaction Entities or any other Person if it does not sell Issuance Shares for any reason other than a failure by JPMorgan to use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such Issuance Shares as required under this Section 2.01. In acting hereunder, JPMorgan will be acting as agent for EQR and not as principal.

(b) Method of Offer and Sale. The Program Shares may be offered and sold in (1) privately negotiated transactions (if and only if the parties hereto have so agreed in writing), or (2) by any other method or payment permitted by law deemed to be an “at the market” offering as defined in Rule 415 of the Securities Act, including sales made directly on the Principal Market or sales made to or through a market maker or through an electronic communications network. Nothing in this Agreement shall be deemed to require either party to agree to the method of offer and sale specified in clause (1) above, and either party may withhold its consent thereto in such party’s sole discretion.

(c) Issuances. Upon the terms and subject to the conditions set forth herein, on any Trading Day as provided in Section 2.03(b) hereof during the Commitment Period on which the conditions set forth in Section 5.01 and 5.02 hereof have been satisfied, EQR may exercise an Issuance by the delivery of an Issuance Notice, executed by the Chief Executive Officer, the President, the Chief Financial Officer, the Senior Vice President-Finance or the Treasurer of EQR, to JPMorgan. JPMorgan shall use its commercially reasonable efforts to sell pursuant to such Issuance a number of Program Shares equal to the Issuance Amount. Each Issuance will be settled on the applicable Settlement Date following the Issuance Date.

Section 2.02 Effectiveness. The effectiveness of this Agreement shall be deemed to take place concurrently with the execution and delivery of this Agreement by the parties hereto. Prior to the first Issuance Notice delivered following the date hereof, the following closing transactions shall take place, each of which shall be deemed to occur simultaneously (the “Closing”): (i) EQR shall deliver to JPMorgan a certificate executed by the Secretary of EQR, signing in such capacity, on behalf of EQR and in its capacity as general partner of ERP, dated the date of the Closing (A) certifying that attached thereto are true and complete copies of the resolutions duly adopted by the Board of Trustees of EQR authorizing the execution and delivery of this Agreement by EQR and the consummation of the transactions contemplated hereby (including, without limitation, the issuance of the Program Shares pursuant to the Sales Agency Agreements), which authorization shall be in full force and effect on and as of the date of such certificate and (B) certifying and attesting to the office, incumbency, due authority and specimen signatures of each Person who executed the Agreement for or on behalf of EQR; (ii) EQR shall deliver to JPMorgan a certificate executed by the Chief Executive Officer, the President or any Senior or Executive Vice-President of EQR and by the Chief Financial Officer of EQR, signing in such capacity, on behalf of EQR and in its capacity as general partner of ERP, dated the date of the Closing, confirming (x) that there has been no Material Adverse Effect since the date as of which information is given in the Prospectus as then amended or supplemented, (y) that the representations and warranties of the Transaction Entities contained in this Agreement are true and correct and (z) that each of the Transaction Entities has performed all of its obligations hereunder to be performed on or prior to the Closing Date and as to the matters set forth in Section 5.01(a) hereof; (iii) DLA Piper LLP (US), counsel to EQR, shall deliver to JPMorgan

opinion letters, dated the date of the Closing and addressed to JPMorgan, substantially in the forms of Exhibit B and Exhibit C attached hereto; (iv) the General Counsel of EQR shall deliver to JPMorgan an opinion, dated the date of the Closing and addressed to JPMorgan, substantially in the form of Exhibit D attached hereto; (v) Xxxxxxxx & Xxxxxxxx LLP, counsel to JPMorgan and the Alternative Sales Agents, shall deliver to JPMorgan and the Alternative Sales Agents an opinion, dated the date of the Closing and addressed to JPMorgan and the Alternative Sales Agents, in form and substance satisfactory to JPMorgan and the Alternative Sales Agents; (vi) Ernst & Young LLP shall deliver to JPMorgan a letter, dated the Closing Date, in form and substance satisfactory to JPMorgan, containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters, with respect to the financial statements of EQR included or incorporated by reference in the Registration Statement, the Prospectus and the General Disclosure Package; and (vii) EQR shall pay the expenses that are payable to JPMorgan pursuant to Section 9.02 hereof by wire transfer to the account designated by JPMorgan in writing prior to the Closing.

Section 2.03 Mechanics of Issuances.

(a) Issuance Notice. On any Trading Day during the Commitment Period, EQR may deliver an Issuance Notice to JPMorgan, subject to the satisfaction of the conditions set forth in Sections 5.01 and 5.02; provided, however, that notwithstanding anything in this Agreement to the contrary, (1) JPMorgan shall not be obligated to sell on any Trading Day a number of Issuance Shares in excess of 25% of the Average Daily Trading Volume of Common Shares on the Principal Exchange without the prior written consent of JPMorgan, which may be withheld in JPMorgan’s sole discretion, and (2) JPMorgan shall have no further obligations with respect to any Issuance Notice if and to the extent the number of the Issuance Shares sold pursuant thereto, together with the aggregate number of the Program Shares previously sold under the Sales Agency Agreements, shall exceed the Maximum Program Amount. EQR shall have the right, in its sole discretion, to amend at any time and from time to time any Issuance Notice; provided, however, that EQR may not amend the Issuance Amount if such amended Issuance Amount is less than the Actual Sold Amount as of the date of such amendment.

(b) Delivery of Issuance Notice. An Issuance Notice shall be deemed delivered on the Trading Day that it is received by facsimile or otherwise (and EQR confirms such delivery by e-mail notice or by telephone (including voicemail message)) by JPMorgan. No Issuance Notice may be delivered other than on a Trading Day during the Commitment Period.

(c) Floor Price. JPMorgan shall not sell Program Shares below the Floor Price during any Selling Period and such Floor Price may be adjusted by EQR at any time during any Selling Period upon notice to JPMorgan and confirmation to EQR.

(d) Determination of Issuance Shares to be Sold. The number of Issuance Shares to be sold by JPMorgan with respect to any Issuance shall be the Actual Sold Amount during the Selling Period.

(e) Trading Guidelines. EQR consents to JPMorgan trading in Program Shares for JPMorgan’s own account and for the account of its clients at the same time as sales of

Program Shares occur pursuant to this Agreement, provided, however, that such consent is expressly limited to trading activity that complies with applicable federal and state laws, rules and regulations.

Section 2.04 Settlements. Subject to the provisions of Article V, on or before each Settlement Date, EQR will, or will cause its transfer agent to, electronically transfer the applicable Issuance Shares that have been sold by crediting JPMorgan or its designee’s account at the Depository Trust Company through its Deposit/Withdrawal At Custodian (DWAC) System, or by such other means of delivery as may be mutually agreed upon by the parties hereto and, upon receipt of such Issuance Shares, which in all cases shall be freely tradeable, transferable, registered shares in good deliverable form, JPMorgan will deliver the related Issuance Price in same day funds delivered to an account designated by EQR prior to the Settlement Date. If EQR defaults in its obligation to deliver Issuance Shares on a Settlement Date, EQR agrees that it will (i) hold JPMorgan harmless against any loss, claim, damage or expense (including, without limitation, penalties, interest and reasonable legal fees and expenses), as incurred, arising out of or in connection with such default by EQR, and (ii) pay to JPMorgan any Selling Commission to which it would otherwise have been entitled absent such default. The parties acknowledge and agree that, in performing its obligations under this Agreement, JPMorgan may borrow Common Shares from stock lenders, and may use the Issuance Shares to settle or close out such borrowings.

Section 2.05 Use of Free Writing Prospectus. Neither EQR nor JPMorgan has prepared, used, referred to or distributed, or will prepare, use, refer to or distribute, without the other party’s prior written consent, which consent shall not be unreasonably withheld, any “written communication” which constitutes a “free writing prospectus” as such terms are defined in Rule 405 under the Securities Act with respect to the offering of Program Shares contemplated by this Agreement.

Section 2.06 Alternative Sales Agents. EQR agrees that any offer to sell, any solicitation of an offer to buy, or any sales of Program Shares or any other equity security of EQR shall only be effected by or through only one of JPMorgan or the Alternative Sales Agents on any single given day, but in no event by more than one, and EQR shall in no event request that JPMorgan and any other Alternative Sales Agent sell Program Shares on the same day.

Section 2.07 Exemption from Regulation M. If any party believes that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act (applicable to securities with an average daily trading volume of $1,000,000 that are issued by an issuer whose common equity securities have a public float value of at least $150,000,000) are not satisfied with respect to EQR or the Program Shares, it shall promptly notify the other party and sales of Program Shares under the Sales Agency Agreements shall be suspended until that or other exemptive provisions have been satisfied in the reasonable judgment of all parties.

Section 2.08 Distributions under Regulation M. Notwithstanding any other provision of this Agreement, in the event EQR engages JPMorgan for a sale of Program Shares that would constitute a “distribution” within the meaning of Rule 100 of Regulation M under the Exchange Act, EQR and JPMorgan will agree to compensation that is customary for JPMorgan with respect to such transactions.

Section 2.09 Material Non-Public Information. Notwithstanding any other provision of this Agreement, JPMorgan shall not be obligated to sell any Program Shares hereunder during (i) any period in which it reasonably believes that EQR is, or could be deemed to be, in possession of material non-public information or (ii) during the fourteen (14) calendar days prior to any public announcement or release disclosing EQR’s results of operations or financial condition for a completed quarterly or annual fiscal period.

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF THE TRANSACTION ENTITIES

Each of EQR and ERP, jointly and severally, represent and warrant to JPMorgan, as of the Closing Date, each Issuance Date, each Settlement Date, each Registration Statement Amendment Date, each Request Date and each Applicable Time (each, a “Representation Date”), as follows:

Section 3.01 EQR and ERP have jointly filed with the Commission an automatic shelf registration statement on Form S-3 (No. 333-190248) for the registration of EQR’s securities, including the Common Shares, under the Securities Act, and the offering thereof from time to time in accordance with Rule 430A or Rule 415 of the rules and regulations of the Commission under the Securities Act (the “Securities Act Regulations”), and EQR and ERP have filed such amendments thereto as may have been required prior to the execution of this Agreement. Such registration statement (as amended, if applicable) became effective upon filing with the Commission. Such registration statement and the base prospectus constituting a part thereof (including in each case the information, if any, deemed to be part thereof pursuant to Rule 430A, Rule 430B or Rule 430C of the Securities Act Regulations) (the “Base Prospectus”) and the Prospectus Supplement and any pricing supplement relating to a particular issuance of the Issuance Shares (the “Issuance Supplement”), including all documents incorporated therein by reference, as from time to time amended or supplemented pursuant to the Securities Act, the Exchange Act or otherwise, are collectively referred to herein as the “Registration Statement.” The term “Prospectus” means the Prospectus Supplement together with the Base Prospectus and any Issuance Supplements; provided, that if any revised prospectus shall be provided to JPMorgan by EQR for use in connection with the offering of Program Shares, including any prospectus included in any new registration statement filed prior to the Renewal Deadline as contemplated in Section 4.01 below, which differs from the Prospectus on file at the Commission at the time the Registration Statement became effective (whether or not such revised prospectus is required to be filed by EQR and ERP pursuant to Rule 424(b) of the Securities Act Regulations), the term “Prospectus” shall refer to each such revised or new prospectus from and after the time it is first provided to JPMorgan for such use; provided, further, that a Prospectus Supplement shall be deemed to have supplemented the Prospectus only with respect to the offering of Program Shares hereunder. If EQR and ERP file a registration statement with the Commission pursuant to Rule 462(b) of the Securities Act Regulations (the “Rule 462 Registration Statement”), then, after such filing, all references to “Registration Statement” shall also be deemed to include the Rule 462 Registration Statement. Any prospectus included in the Rule 462 Registration Statement shall be deemed to be part of the Prospectus. All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Registration Statement or the Prospectus (and all other references of like import) shall be deemed to mean and include all such financial statements and

schedules and other information which is or is deemed to be incorporated by reference in the Registration Statement or the Prospectus; and all references in this Agreement to amendments or supplements to the Registration Statement and the Prospectus shall be deemed to mean and include the filing of any document under the Exchange Act which is or is deemed to be incorporated by reference in the Registration Statement or the Prospectus, as the case may be.

Section 3.02 The Registration Statement and the Prospectus, at the time the Registration Statement and any post-effective amendment thereto (including the filing of the most recent Annual Report on Form 10-K and the most recent Quarterly Report on Form 10-Q of EQR and ERP with the Commission) became effective, complied, and as of each Representation Date will comply, in all material respects with the requirements of the Securities Act and the Securities Act Regulations; the Prospectus, at the time of filing thereof, complied, and as of each Representation Date will comply, in all material respects with the requirements of the Securities Act and the Securities Act Regulations; the Registration Statement, at the time the Registration Statement became effective, did not, and as of each Representation Date, will not, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; the Prospectus, at the time of filing thereof, did not, and as of each Representation Date, 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 under which they were made, not misleading; the Prospectus, as of each Representation Date, and the applicable Issuer Free Writing Prospectus(es), if any, issued at or prior to the Applicable Time, taken together (collectively, and, with respect to any Program Shares, together with the public offering price of such Program Shares, the “General Disclosure Package”) as of each Applicable Time and the Closing Date, as the case may be, will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the representations and warranties in this subsection shall not apply to statements in, or omissions from, the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus(es) made in reliance upon, and in conformity with, information furnished to EQR and ERP in writing by JPMorgan expressly for use in the Registration Statement, the Prospectus or the Issuer Free Writing Prospectus(es), as applicable; and provided further, that the foregoing representations and warranties are given on the basis that any statement contained in a document incorporated or deemed to be incorporated in the General Disclosure Package prior to any Settlement Date shall be deemed not to be contained in the General Disclosure Package to the extent that such statement has been modified or superseded by any subsequent statement in the General Disclosure Package.

Section 3.03(A) At the time of filing the Registration Statement, (B) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Securities Act (whether such amendment was by post-effective amendment or incorporated report filed pursuant to Section 13 or 15(d) of the Exchange Act or form of prospectus), (C) at the time EQR or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c) of the Securities Act) made any offer relating to the Program Shares in reliance on the exemption of Rule 163 of the Securities Act, and (D) as of the date of the execution and delivery of this Agreement, EQR was and is a “well-known seasoned issuer” as defined in Rule 405 of the Securities Act. The Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405 of the Securities Act, that initially became effective within three years of the

date hereof, EQR has not received from the Commission any notice pursuant to Rule 401(g)(2) of the Securities Act objecting to use of the automatic shelf registration statement form and EQR has not otherwise ceased to be eligible to use the automatic shelf registration statement form. EQR and ERP meet the eligibility requirements for use of a registration statement on Form S-3 in connection with the offer and sale of the Program Shares.

Section 3.04(A) At the earliest time after the filing of the Registration Statement relating to the Program Shares that EQR or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) of the Securities Act) and (B) as of the date of the execution and delivery of this Agreement, EQR was not and is not an Ineligible Issuer (as defined in Rule 405 of the Securities Act), without taking into account any determination by the Commission pursuant to Rule 405 of the Securities Act that it is not necessary that EQR be considered an Ineligible Issuer.

Section 3.05 Other than the Prospectus, neither EQR nor ERP (including their agents and representatives, other than JPMorgan and the Alternative Sales Agents in their capacity as such) has made, used, prepared, authorized, approved or referred to, nor will they make, use, prepare, authorize, approve or refer to, any “written communication” (as defined in Rule 405 under the Securities Act) that constitutes an offer to sell or solicitation of an offer to buy the Program Shares (each such communication by EQR, ERP or their respective agents and representatives (other than a communication referred to in clause (i) below) an “Issuer Free Writing Prospectus”) other than (i) any document not constituting a prospectus pursuant to Section 2(a)(10)(a) of the Securities Act or Rule 134 under the Securities Act or (ii) other written communications approved in writing in advance by JPMorgan. Each such Issuer Free Writing Prospectus complied in all material respects with the requirements of the Securities Act Regulations, has been filed in accordance with the Securities Act Regulations (to the extent required thereby) and, when taken together with the Prospectus filed prior to the first use of such Issuer Free Writing Prospectus, did not, and at the time of Closing 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 under which they were made, not misleading; provided that neither Transaction Entity makes any representation or warranty with respect to any statements or omissions made in each such Issuer Free Writing Prospectus in reliance upon and in conformity with information relating to JPMorgan or any Alternative Sales Agent and furnished to EQR and ERP in writing by JPMorgan or such Alternative Sales Agent expressly for use in any Issuer Free Writing Prospectus.

Section 3.06 No stop order suspending the effectiveness of the Registration Statement or any part thereof has been issued and no proceeding for that purpose has been instituted or, to the knowledge of EQR and ERP, threatened by the Commission or by the state securities authority of any jurisdiction. No order preventing or suspending the use of the Prospectus has been issued and no proceeding for that purpose has been instituted or, to the knowledge of EQR and ERP, threatened by the Commission or by the state securities authority of any jurisdiction. Any request on the part of the Commission for additional information relating to the Program Shares or the Prospectus has been complied with.

INDEMNIFICATION AND CONTRIBUTION

Section 6.01 Indemnification by the Transaction Entities. Each of EQR and ERP hereby agrees, jointly and severally, to indemnify and hold harmless JPMorgan and each person, if any, who controls JPMorgan within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and any director, officer, employee or affiliate thereof, as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or

supplement thereto), the Prospectus Supplement, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or the omission, or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation or of any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, provided that (subject to Section 6.03 below) any such settlement is effected with the written consent of EQR; and

(iii) against any and all expense whatsoever as incurred (including, without limitation, the fees and other charges of counsel chosen by you) reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent such loss, liability, claim, damage or expense arises out of any untrue statement or omission or alleged untrue statement or omission made in the Registration Statement (or any amendment thereto), the Prospectus (or any amendment or supplement thereto), the Prospectus Supplement, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, in reliance upon and in conformity with written information furnished to EQR by JPMorgan expressly for use in the Registration Statement (or any amendment thereto), the Prospectus (or any amendment or supplement thereto), the Prospectus Supplement, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act.

Section 6.02 Indemnification by JPMorgan. JPMorgan agrees to indemnify and hold harmless each of EQR and ERP, and each person, if any, who controls EQR or ERP within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and any trustee, director, officer, employee or affiliate thereof, against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 6.01, as incurred; but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), the Prospectus (or any amendment or supplement thereto), the Prospectus Supplement, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, in reliance upon, and in conformity with, written information furnished to EQR by JPMorgan expressly for use in the Registration Statement (or any amendment thereto), the Prospectus (or any amendment or supplement thereto), the Prospectus Supplement, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act.

Section 6.03 Conduct of Indemnification Proceedings.

(a) Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6.01 above, counsel to the indemnified parties shall be selected by JPMorgan, and, in the case of parties indemnified pursuant to Section 6.02 above, counsel to the indemnified parties shall be selected by EQR. An indemnifying party may participate at its own expense in the defense of any such action provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under Section 6.01, Section 6.02 or Section 6.04 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(b) If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6.01(ii) 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.

Section 6.04 Contribution. If the indemnification provided for in Section 6.01 and Section 6.02 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect benefits received by EQR, on the one hand, and JPMorgan, on the other hand, from the offering of the Program Shares to which such losses, liabilities, claims, damages or expenses relate or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of EQR, on the one hand, and of JPMorgan, on the other hand, in connection with the statements or omissions which resulted in

such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations. The relative benefits received by EQR on the one hand and JPMorgan on the other shall be deemed to be in the same proportion as the total net proceeds from the offering of Program Shares (before deducting expenses) received by EQR bear to the total commissions received by JPMorgan.

The relative fault of EQR, on the one hand, and JPMorgan, 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 EQR or by JPMorgan and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

EQR and JPMorgan agree that it would not be just and equitable if contribution pursuant to this Section 6.04 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 6.04. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 6.04 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 6.04, JPMorgan shall not be required to contribute any amount in excess of the amount by which the total price at which the Program Shares sold by it were sold to the public exceeds the amount of any damages which JPMorgan has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

Form of Corporate Opinion of DLA Piper LLP (US), Counsel for EQR

Re:	Equity Residential

Up to 13,000,000 Common Shares of Beneficial Interest, par value $0.01 per share

Ladies and Gentlemen:

As special counsel for Equity Residential, a Maryland real estate investment trust (the “Company”), we address this letter to each of you as the Sales Agents (the “Sales Agents”) named in the five sales agency financing agreements each amended and restated or dated July 31, 2013 (the “Sales Agency Financing Agreements”), among each of you individually, the Company and ERP Operating Limited Partnership, an Illinois limited partnership (the “Operating Partnership”), with respect to the issuance and sale by the Company through the Sales Agents, as sales agents, of up to 13,000,000 shares (the “Shares”) of the Company’s common shares of beneficial interest, par value $0.01 per share (the “Common Shares”). We are delivering this letter to you at the request of the Company pursuant to [Section 2.02] [Section 4.07] of each of the Sales Agency Financing Agreements.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (Registration No. 333-190248) for the registration of the Common Shares and certain of its other securities under the Securities Act of 1933, as amended (the “1933 Act”). Such registration statement and the Incorporated Documents (as defined below) are hereinafter called, collectively and after giving effect to Rule 412 of the 1933 Act Regulations (as defined below), the “Registration Statement.”

In connection with the issuance and sale of the Common Shares, the Company has prepared (i) a prospectus dated July 30, 2013 (the “Base Prospectus”) and (ii) a prospectus supplement dated July 31, 2013 (the “Prospectus Supplement”). The Prospectus Supplement and the accompanying Base Prospectus, in the form filed with the Commission pursuant to Rule 424(b) of the 1933 Act Regulations, together with the Incorporated Documents, are hereinafter called, collectively and giving effect to Rule 412 of the 1933 Act Regulations, the “Prospectus.”

As used herein, the term “Incorporated Documents,” when used with respect to the Registration Statement or the Prospectus as of any date, means the documents incorporated or deemed to be incorporated by reference in the Registration Statement or the Prospectus, as the case may be, as of such date pursuant to Item 12 of Form S-3; the term “1933 Act Regulations” means the rules and regulations of the Commission under the 1933 Act; the term “Title 8” means Title 8 of the Corporations and Associations Article of the Annotated Code of Maryland; the term “IL Limited Partnership Act” means the Illinois Uniform Limited Partnership Act (2001); and the term “Applicable Laws” means (i) Title 8; and (ii) those laws of the State of Illinois and the State of New York and those federal laws of the United States of America which, in our experience, are normally applicable to transactions of the type contemplated by the Sales Agency Financing Agreements (provided that the term “Applicable Laws” shall not include federal or state securities or blue sky laws, including, without limitation, the 1933 Act, the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the Investment Company Act of 1940, as amended (the “1940 Act”), and the respective rules and regulations thereunder or any antifraud laws or regulations).

B-1

As special counsel for the Company, we have examined and relied upon originals or copies, certified or otherwise identified to our satisfaction, of such agreements, instruments, certificates, records and other documents as we have deemed necessary or appropriate for the purpose of rendering the opinions set forth in this letter. In our examination, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified or photostatic copies or by facsimile or other means of electronic transmission or which we obtained from the Commission’s Electronic Data Gathering, Analysis and Retrieval system (“XXXXX”) or other sites on the internet, and the authenticity of the originals of such latter documents. As to facts and other matters relevant to the opinions expressed herein and the other statements made herein, we have relied without independent investigation or verification upon, and assumed the accuracy and completeness of, (a) certificates, letters and oral and written statements and representations of public officials, officers and other representatives of the Company, accountants for the Company, and others, and (b) the representations and warranties in the Sales Agency Financing Agreements and the Registration Statement.

Based on and subject to the foregoing and the other limitations, qualifications, exceptions and assumptions set forth herein, we are of the opinion that:

1. The Company is a real estate investment trust validly existing under and by virtue of Title 8 and is in good standing with the State Department of Assessments and Taxation of Maryland.

2. The Operating Partnership is a limited partnership validly existing and in good standing under the IL Limited Partnership Act.

3. The Company has the real estate investment trust power and authority to own, lease and operate its properties and to conduct its business as described in the Prospectus and to execute, deliver and perform its obligations under each of the Sales Agency Financing Agreements.

4. The Operating Partnership has the limited partnership power and authority to execute, deliver and perform its obligations under each of the Sales Agency Financing Agreements.

5. No consent, approval, authorization or order of, or registration or filing with, any court or other governmental or regulatory authority or agency is required under Applicable Laws for the execution and delivery by each of the Company and the Operating Partnership of each of the Sales Agency Financing Agreements or the issuance of the Shares by the Company pursuant to, or the performance of the obligations of each of the Company and the Operating Partnership under, each of the Sales Agency Financing Agreements.

B-2

6. Each of the Sales Agency Financing Agreements has been duly authorized, executed and delivered by each of the Company and the Operating Partnership.

7. The Shares have been duly authorized by the Company for issuance and sale pursuant to the Sales Agency Financing Agreements. When (i) the purchase price or prices for the Shares and the number of Shares (in any case not to exceed 13,000,000 in the aggregate under the Sales Agency Financing Agreements) to be offered and sold from time to time have been duly established and approved by resolutions duly adopted by the Company’s board of trustees or a duly authorized committee thereof (the “Board”), in accordance with the resolutions authorizing the issuance thereof and agreed upon by the Company and the respective purchasers of the Shares, and (ii) the Shares have been issued and delivered by the Company against payment of such purchase price or prices, as the case may be, in accordance with the relevant Sales Agency Financing Agreement, after deduction from such purchase price or prices of the Sales Agent’s commission and such other amounts, if any, as may be deducted therefrom in accordance with such Sales Agency Financing Agreement and resolutions duly adopted by the Board, the Shares will be validly issued, fully paid and nonassessable; provided, that (A) the purchase price per Share paid by purchasers is equal to or in excess of the par value per Common Share and in excess of any minimum purchase price, and within any other parameters, established by the Board and (B) the aggregate number of Shares issued and issuable pursuant to the Sales Agency Financing Agreements, when taken together with the other issued and outstanding Common Shares (including any treasury shares), does not exceed the number of authorized Common Shares set forth in the Articles of Restatement of Declaration of Trust of the Company. The issuance and sale of the Shares pursuant to the Sales Agency Financing Agreements is not subject to any preemptive rights of any securityholder of the Company arising under Title 8 as currently in effect or the Articles of Restatement of Declaration of Trust of the Company or the Seventh Amended and Restated Bylaws of the Company, each as currently in effect.

8. The Registration Statement became effective under the 1933 Act; the Prospectus has been filed pursuant to the 1933 Act Regulations; and, to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued under the 1933 Act and no proceedings for that purpose have been instituted or are pending by the Commission.

9. The Registration Statement, as of the date it first became effective, and the Prospectus, as of the date of the Prospectus Supplement, each appeared on its face to be appropriately responsive in all material respects to the applicable requirements of the 1933 Act and the 1933 Act Regulations for registration statements on Form S-3 or related prospectuses, as the case may be, except in each case that we express no opinion in this paragraph 9 with respect to (i) financial statements and schedules and other financial or statistical data derived from financial statements included or incorporated by reference therein or omitted therefrom and (ii) the Incorporated Documents.

10. The documents incorporated by reference in the Prospectus, at the respective times such documents were filed with the Commission, each appeared on its face to be appropriately responsive in all material respects with the applicable

B-3

requirements of the Exchange Act and the rules and regulations of the Commission promulgated thereunder, except in each case that we express no opinion with respect to financial statements and schedules and other financial or statistical data derived from financial statements included or incorporated by reference therein or omitted therefrom.

11. The statements set forth in the Base Prospectus under the heading “Description of Equity Residential Securities — Common Shares,” to the extent such statements purport to describe certain provisions of the Common Shares as set forth in the Articles of Restatement of Declaration of Trust of the Company as currently in effect, accurately describe such provisions in all material respects, except that, we express no opinion in this paragraph 11 to the effect that any Common Shares will be duly authorized, fully paid and nonassessable.

12. The execution, delivery and performance by each of the Company and the Operating Partnership of each of the Sales Agency Financing Agreements and the consummation by each of the Company and the Operating Partnership of the transactions contemplated thereby (i) do not violate any provision of Applicable Laws, and (ii) do not violate any provision of the Articles of Restatement of Declaration of Trust of the Company or the Seventh Amended and Restated Bylaws of the Company or any provision of the Certificate of Limited Partnership of the Operating Partnership or the Sixth Amended and Restated Agreement of Limited Partnership of the Operating Partnership, provided that the Shares are issued and sold in accordance with the proviso to the second sentence of paragraph 7 above, and except that we express no opinion with respect to any indemnification or contribution provisions contained in any of the Sales Agency Financing Agreements.

13. The Company is not required to be registered as an “investment company” within the meaning of the 1940 Act.

In acting as counsel to the Company in connection with the offer and sale of the Shares, we have participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants for the Company and your representatives and counsel, at which conferences certain contents of the Registration Statement and the Prospectus and related matters were discussed. Although we are not passing upon or assuming responsibility for the accuracy, completeness or fairness of the statements included or incorporated by reference in or omitted from the Registration Statement, the Prospectus or the Incorporated Documents and have made no independent check or verification thereof (except as set forth in paragraph 11 above), based upon our participation in such conferences, no facts have come to our attention which have caused us to believe that:

(A) the Registration Statement (including the information in the Prospectus that was omitted from the Registration Statement at the time it first became effective but that is deemed, pursuant to, and within the meaning of, Rule 430B(f) under the 1933 Act Regulations, to be part of and included in the Registration Statement), as of the date of the Sales Agency Financing Agreements and at the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading; or

B-4

(B) the Prospectus, as of the date hereof, includes an untrue statement of a material fact or omits 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;

except in each case that we express no belief and make no statement with respect to financial statements and schedules and other financial or statistical data derived from the financial statements included or incorporated by reference in or omitted from the Registration Statement or the Prospectus.

The foregoing opinions and other statements are subject to the following qualifications, exceptions, assumptions and limitations:

A. The foregoing opinions and other statements are limited to matters arising under the federal laws of the United States of America, the laws of the State of Illinois, the laws of the State of New York and Title 8. We express no opinion and make no statement as to the laws, rules or regulations of any other jurisdiction or, in the case of Maryland, any other Maryland laws, rules or regulations, or as to the municipal laws or the laws, rules or regulations of any local agencies or governmental authorities of or within the State of Illinois or the State of New York, or in each case as to any matters arising thereunder or relating thereto.

B. In rendering our opinion set forth in paragraphs 1 and 2 above, we have relied solely upon a certificate or certificates, as the case may be, of a governmental authority or official dated on or about the date hereof.

C. In rendering our opinion set forth in paragraph 8 above with respect to the effectiveness of the Registration Statement and the filing of the Prospectus, we have relied upon our review of the XXXXX website. In rendering our opinion set forth in paragraph 8 above with respect to the absence of stop orders or proceedings, we have relied solely upon confirmation from the Commission on the date hereof, either via telephonic call with the staff of the Commission or via xxx.xxx.xxx.

D. In rendering our opinion set forth in paragraph 13 above, we have relied exclusively, as to all factual matters, on the certificate, dated as of the date of this letter, of Xxxx X. Xxxxxxx, Executive Vice President and Chief Financial Officer of the Company, and Xxxxx X. Xxxxxx, Executive Vice President, General Counsel and Corporate Secretary of the Company.

E. Any opinion or statement herein which is expressed to be “to our knowledge” or is otherwise qualified by words of like import means that the lawyers currently practicing law with the Firm who have had active involvement in representing the Company in connection with the issuance and sale of the Shares and our lawyers who have principal responsibility for representing the Company on other matters in areas relevant to the opinions being rendered or the statements being made, have no current conscious awareness of any facts or information contrary to such opinion or statement. Except to the extent expressly set forth in this letter, we have not undertaken any independent investigation to determine the existence or absence of any fact, and no inference as to our knowledge of the existence or absence of any fact should be drawn from our representation of the Company or the rendering of this letter.

The opinions expressed and the statements made herein are expressed and made on the date hereof and we assume no obligation to advise you of changes in law, fact or other circumstances (or the effect thereof on such opinions or statements) that may come to our attention after such time.

B-5

We call your attention to the fact that, although we represent the Company in connection with the subject transaction, our engagement has been limited to the specific matters as to which we have been consulted.

This letter is being rendered and delivered solely to and for the benefit of the persons to whom it is addressed; accordingly, it may not be delivered to or relied upon by any other person (including, without limitation, any person who acquires the Shares from or through any of the Sales Agents), quoted or filed with any governmental authority or other regulatory agency or otherwise circulated or utilized for any other purpose without our prior written consent, except that Xxxxxxxx & Xxxxxxxx LLP may rely upon our opinion set forth in paragraph 6 above to the extent that such opinion relates to the Operating Partnership and matters arising under the laws of the State of Illinois for the sole purpose of rendering its opinion pursuant to [Section 2.02] [Section 4.07] of the Sales Agency Financing Agreements.

Very truly yours,

company, and BEL Residential Properties Trust, a Maryland real estate investment trust (each such entity, along with BEL Multifamily Property Trust, a Maryland real estate investment trust, BEL Communities Property Trust, a Maryland real estate investment trust, and BEL Apartment Properties Trust, a Maryland real estate investment trust, hereinafter referred to as a “Subsidiary REIT”)], contained in EQR’s certificate to us, dated as of the date hereof (the “Officer’s Certificate”), executed by a duly appointed officer of EQR setting forth certain representations and covenants relating to the organization and operation of EQR, the Operating Partnership, the Subsidiary REITs and their respective subsidiaries.

Although we have made such inquiries and performed such investigations as we have deemed necessary for purposes of our opinion, we have not independently verified all of the facts, statements, representations and covenants set forth in the Officer’s Certificate, the Prospectus, or in any other document. We consequently have assumed that the information presented in such documents or otherwise furnished to us accurately and completely describes all material facts relevant to our opinion. We are not aware of any facts that are inconsistent with any of the representations made to us in the Officer’s Certificate. Any representation or statement in any document upon which we rely that is made “to the best knowledge of” or otherwise similarly qualified is assumed to be true, correct and complete as if made without such qualification as to knowledge or belief. Any alteration or inaccuracy of such facts, statements, representations or covenants may adversely affect our opinions.

For purposes of our opinion, we have assumed that all of the representations and statements of a factual nature set forth in the documents we reviewed are true, correct and complete, and all of the obligations imposed by any such documents on the parties thereto have been and will be performed or satisfied in accordance with their terms. We have also assumed the legal capacity of all natural persons, the genuineness of all signatures, the proper execution of all documents, the authenticity of all documents submitted to us as originals, the conformity to originals of documents submitted to us as copies, and the authenticity of the originals from which any copies were made.

The opinions set forth in this letter are based on relevant provisions of the Internal Revenue Code of 1986, as amended (the “Code”), the regulations promulgated thereunder by the United States Department of the Treasury (the “Regulations”) (including proposed and temporary Regulations), and interpretations of the foregoing as expressed in court decisions, legislative history, and existing administrative rulings and practices of the Internal Revenue Service (“IRS”) (including its practices and policies in issuing private letter rulings, which are not binding on the IRS except with respect to a taxpayer that receives such a ruling), all as of the date hereof.

In rendering these opinions, we have assumed that the transactions contemplated by the Reviewed Documents will be consummated in accordance with the terms and provisions of such documents, and that such documents accurately reflect the material facts of such transactions. In addition, the opinions set forth herein are based on the correctness of the following specific assumptions:

(i)

EQR, the Operating Partnership, the Subsidiary REITs and their respective subsidiaries will each be operated in the manner described in the Declaration of

C-2

Trust, the ERP LP Agreement, and the other organizational documents of each such entity, as the case may be, and all terms and provisions of such agreements and documents will be complied with by all parties thereto;

(ii)

EQR is a duly formed real estate investment trust under the laws of the State of Maryland;

(iii)

The Operating Partnership is a duly organized and validly existing limited partnership under the laws of the State of Illinois; and

(iv)

There will be no change in the applicable laws of the State of Maryland, the State of Illinois, or in the Code, the Regulations, and the interpretations of the Code and such Regulations by the courts and the IRS, after the date of this letter.

With respect to the last assumption, it should be noted that statutes, regulations, judicial decisions, and administrative interpretations are subject to change at any time and, in some circumstances, with retroactive effect. A material change that is made after the date hereof in any of the foregoing bases for our opinions could affect our conclusions. Furthermore, if the facts vary from those relied upon (including if any representations, warranties, covenants or assumptions upon which we have relied are inaccurate, incomplete, breached or ineffective), our opinion contained herein could be inapplicable.

The qualification and taxation of EQR as a real estate investment trust (“REIT”) under the Code will depend upon (i) EQR’s meeting, in its actual operations, the applicable asset composition, source of income, shareholder diversification, distribution and other requirements of the Code and Regulations necessary for an entity to qualify as a REIT and (ii) the satisfaction by each of the Subsidiary REITs of the requirements for qualification and taxation as a REIT. We will not review the operations of EQR or any of the Subsidiary REITs, and no assurance can be given that the actual operations of EQR or any Subsidiary REIT will meet these requirements or the representations made to us with respect thereto.

Based upon and subject to the foregoing, it is our opinion that:

(i)

EQR was organized and has operated in conformity with the requirements for qualification and taxation as a REIT under the Code for each of its taxable years ended December 31, 1992 through December 31, 2012, and EQR’s current organization and proposed method of operation will enable it to continue to meet the requirements for qualification and taxation as a REIT under the Code for its taxable years ending after the date of this opinion.

(ii)

Although the discussion set forth in the Base Prospectus under the heading “Federal Income Tax Considerations Related to Common Shares” (as supplemented by the discussion in the Prospectus Supplement under the heading “Supplemental Federal Income Tax Considerations”) does not purport to summarize all possible U.S. federal income tax consequences of the purchase, ownership, and disposition of the Common Shares, such discussion, though general in nature, constitutes, in all material respects, a fair and accurate summary of the material U.S. federal income tax consequences of the purchase, ownership, and disposition of the Common Shares, subject to the qualifications set forth therein. The U.S. federal income tax consequences of the ownership and disposition of the Common Shares by an investor will depend upon that investor’s particular situation, and we express no opinion as to the completeness of such discussion as applied to any particular holder.

C-3

The foregoing opinion is limited to the matters specifically discussed herein, which are the only matters to which you have requested our opinion. Other than as expressly stated above, we express no opinion on any issue relating to EQR or any investment therein, the Operating Partnership, any Subsidiary REIT, or under any other law.

This opinion should not be construed as or deemed to be a guaranty or insuring agreement. You should be aware that an opinion of counsel represents only counsel’s best legal judgment, and has no binding effect or official status of any kind, and that no assurance can be given that the IRS will not challenge the conclusions of the opinion set forth herein or that any such challenge will not be successful or that a court considering the issues would not hold contrary to the opinions set forth herein.

This opinion is rendered only to you pursuant to [Section 2.02] [Section 4.07] of each of the Sales Agency Financing Agreements, and may not be quoted in whole or in part or otherwise used, circulated or referred to, or be filed with, or furnished to, any other person or entity (including, without limitation, any person who acquires the Common Shares from or through the Sales Agents). This opinion is expressed as of the date hereof, and we are under no obligation to supplement or revise our opinion to reflect any legal developments or factual matters arising subsequent to the date hereof, or the impact of any information, document, certificate, record, statement, representation, covenant, or assumption relied upon herein that becomes incorrect or untrue.

* * *

To comply with certain Regulations, we inform you that (i) this opinion was written to support the promotion and marketing by others of the transactions or matters addressed herein, (ii) this opinion was not intended or written to be used, and cannot be used, by any person for the purpose of avoiding United States federal tax penalties that may be imposed on such person, and (iii) each taxpayer should seek advice based on the taxpayer’s particular circumstances from an independent tax advisor.

Very truly yours,

EXHIBIT D

Form of Opinion of Xxxxx X. Xxxxxx, Executive Vice President,

General Counsel and Corporate Secretary of EQR

Re:	Equity Residential

Up to 13,000,000 Common Shares of Beneficial Interest

Ladies and Gentlemen:

I am Executive Vice President, General Counsel and Corporate Secretary of Equity Residential, a Maryland real estate investment trust (the “Company”). I address this letter to each of you as the Sales Agents (the “Sales Agents”) named in each of the five sales agency financing agreements each amended and restated or dated July 31, 2013 (the “Sales Agency Financing Agreements”) among each of you individually, the Company and ERP Operating Limited Partnership, an Illinois limited partnership (the “Operating Partnership”), with respect to the issuance and sale by the Company through the Sales Agents, as sales agents, of up to 13,000,000 common shares of beneficial interest, par value $0.01 per share of the Company (the “Common Shares”).

The opinions stated below are based on my participation in the issuance and sale of the Common Shares and I have relied to the extent I deemed appropriate, as to various questions of fact material to such opinions, upon the representations made by the Company and the Operating Partnership in each of the Sales Agency Financing Agreements and upon certificates of officers of each of the Company and the Operating Partnership. In rendering the opinions expressed below, I am familiar with the actions taken by the Company in respect thereof and have examined originals or certified or attested copies of the Articles of Restatement of Declaration of Trust of the Company and the Seventh Amended and Restated Bylaws of the Company and the charters, limited liability company agreements, limited partnership agreements and by-laws, as applicable, of the Subsidiaries, including the Operating Partnership, and such other certificates, records or documents as I have deemed necessary to enable me to render this opinion letter.

For purposes of this opinion letter, the following terms shall have the following meanings:

“Base Prospectus” shall mean the prospectus dated July 30, 2013 included in the Registration Statement, including the Incorporated Documents.

“Incorporated Documents” when used with respect to the Registration Statement, or Prospectus as of any date, means the documents incorporated or deemed to be incorporated by reference in the Registration Statement or the Prospectus, as the case may be, as of such date pursuant to Item 12 of Form S-3.

“Prospectus” shall mean the Prospectus Supplement, together with the Base Prospectus.

D-1

“Prospectus Supplement” shall mean the Company’s prospectus supplement dated July 31, 2013 (including all Incorporated Documents), specifically relating to the Common Shares and the Base Prospectus.

“Registration Statement” shall mean, as of any time referred to herein, the Company’s registration statement on Form S-3 (Registration No. 333-190248 filed with the Commission on July 30, 2013, which registration statement became effective on July 30, 2013), as amended at such time, including all exhibits thereto (but excluding Form T-1) and the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act and any prospectus supplement relating to the Common Shares that was filed with the Commission and deemed to be part of and included in the Registration Statement pursuant to Rule 430B(f)(1) under the Securities Act.

“Securities Act” shall mean the Securities Act of 1933, as amended.

“Subsidiary” shall mean a “significant subsidiary” as defined by Rule 1-02 of Regulation S-X under the Securities Act.

Capitalized terms not otherwise defined herein are defined as set forth in each of the Sales Agency Financing Agreements.

Pursuant to the requirements of [Section 2.02] [Section 4.07] of each of the Sales Agency Financing Agreements, this will advise you that in the opinion of the undersigned:

1. To my knowledge, each of the Company and the Operating Partnership is duly qualified and in good standing and authorized to transact business in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except where the failure to be so qualified or in good standing would not have a Material Adverse Effect.

2. Each of the Company’s Subsidiaries has been duly incorporated or formed and is validly existing, and in good standing under the laws of the jurisdiction of its incorporation or formation, has the corporate, limited liability company or limited partnership power and authority to own, lease and operate its properties and to conduct its business as described in the Prospectus, and, to my knowledge, is duly qualified and in good standing and authorized to transact business in any jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except where the failure to be validly existing, so qualified or in good standing would not have a Material Adverse Effect; all of the issued and outstanding shares of capital stock, limited liability company interests and partnership interests of each Subsidiary have been duly authorized and validly issued, are, in the case of shares of capital stock, fully paid, and with respect to the shares of capital stock, limited liability company interests, and partnership interests of each Subsidiary owned by the Company, the Operating Partnership or another subsidiary of the Company or the Operating Partnership, are owned by the Company, the Operating Partnership or another subsidiary of the Company or the Operating Partnership, to my knowledge, free and clear of any security interest, mortgage, pledge, lien, encumbrance, claim or equity, except where any such security interest, mortgage, pledge, xxxx,

X-0

encumbrance, claim or equity would not have a Material Adverse Effect. None of the outstanding shares of capital stock, limited liability company interests or partnership interests of any Subsidiary were issued in violation of statutory preemptive rights or, to my knowledge, contractual rights of any security holder of such Subsidiary to subscribe for more shares of capital stock, limited liability company interests or partnership interests, except where such violation would not have a Material Adverse Effect.

3. The execution and delivery by each of the Company and the Operating Partnership of each of the Sales Agency Financing Agreements, the issuance of the Common Shares by the Company, and the performance of the obligations of each of the Company and the Operating Partnership, under each of the Sales Agency Financing Agreements and the consummation by each of the Company and the Operating Partnership of the transactions contemplated thereby, will not, to my knowledge, conflict with or constitute a breach of, or default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any of its Subsidiaries pursuant to any material agreement or other instrument that is binding upon the Company or any of its Subsidiaries, or to which any of their properties or assets is subject.

4. To my knowledge, there are no (A) legal or governmental proceedings pending or threatened which are required to be disclosed in the Registration Statement or the Prospectus, other than those disclosed therein, or (B) statutes, regulations, contracts, indentures, mortgages, loan agreements, notes, leases, instruments or other documents that are required to be described in the Prospectus or to be filed as exhibits to the Registration Statement that are not described or filed as required.

5. The statements set forth in the Company’s and the Operating Partnership’s combined Annual Report on Form 10-K for the year ended [December 31, 2012] [and the Company’s and the Operating Partnership’s combined Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2013] under the heading “Legal Proceedings,” insofar as such statements purport to summarize certain legal matters, documents or proceedings or legal conclusions, to my knowledge, fairly summarize in all material respects the matters therein described.

This opinion letter is limited to Title 8 of the Corporations and Associations Article of the Annotated Code of Maryland, those laws of the State of Illinois that are normally applicable to transactions of the type contemplated by the Sales Agency Financing Agreements and the federal laws of the United States of America. In rendering my opinions regarding due qualification, valid existence and good standing set forth in paragraphs 1 and 2 above, I have relied solely upon certificates of governmental authorities or officials or information relating to the existence and good standing of the Company and the Operating Partnership obtained from the official website of the applicable governmental authority or official in states in which the Company or the Operating Partnership are incorporated in or conduct their business. This opinion letter is based on the law in effect, and the facts and circumstances existing, on the date of this letter. I assume no obligation to update or supplement this opinion letter to reflect any facts or circumstances which may hereafter come to my attention with respect to the opinions and statements expressed above, including any changes in applicable law which may hereafter occur.

D-3

This opinion letter is being rendered and delivered solely to and for the benefit of the persons to whom it is addressed; accordingly, it may not be delivered to or relied upon by any other person (including, without limitation, any person who acquires the Common Shares from or through any of the Sales Agents), quoted or filed with any governmental authority or other regulatory agency or otherwise circulated or utilized for any other purpose without my prior written consent.

Very truly yours,

Xxxxx X. Xxxxxx

Executive Vice President, General Counsel and Corporate Secretary
