(ee) No subsidiary of the Company is currently prohibited, directly or indirectly, from paying any dividends or distributions to the Company, from making any other distribution on such subsidiary’s capital stock or equity interests, from repaying to the Company any loans or advances to such subsidiary from the Company or from transferring any of such subsidiary’s property or assets to the Company or any other subsidiary of the Company, except pursuant to (i) the terms of any indebtedness or (ii) the terms of the Joint Venture Equity Commitment Letter, in each case set forth in or contemplated in the Disclosure Package and the Prospectus (exclusive of any supplement thereto) or as would not reasonably be expected to have a Material Adverse Effect.

(mm) Neither the Company nor any of its subsidiaries nor, to the knowledge of the Company, any director, officer, agent, employee, affiliate or other person acting on behalf of the Company or any of its subsidiaries is aware of or has taken any action, directly or indirectly, that could result in a violation or a sanction for violation by such persons of the Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations thereunder (“FCPA”), or the U.K. Xxxxxxx Xxx 0000, as may be amended (the “U.K. Bribery Act”), or similar law of any other relevant jurisdiction, or the rules or regulations thereunder; and the Company and its subsidiaries have instituted and maintain policies and procedures designed to ensure compliance therewith.

The parties acknowledge and agree that this representation and warranty is made solely between the Representatives and the Company and the Operating Partnership, and may not be relied upon by any other party for any other purpose. The parties acknowledge and agree that this representation and warranty does not affect any agreement or liability allocation between the Sellers, the Purchasers and the other parties to the Purchase Agreement.

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

2. Representations and Warranties by the Forward Sellers. Each of the Forward Sellers, severally and not jointly, represents and warrants to each Underwriter, the Company and the Operating Partnership as of the date hereof, at the Applicable Time and as of the Closing Date and each Date of Delivery as follows:

(a) This Agreement has been duly authorized, executed and delivered by such Forward Seller and, assuming due authorization, execution and delivery by the Company and the Operating Partnership, is a legal, valid and binding obligation of such Forward Seller, enforceable against such Forward Seller in accordance with its terms, except to the extent that such enforceability may be limited by applicable bankruptcy, insolvency, reorganization or other similar laws relating to or affecting creditors’ rights and general principles of equity and except as rights to indemnity and contribution thereunder may be limited by applicable law or policies underlying such law. At the Closing Date or Date of Delivery, as applicable, such Forward Seller will have full right, power and authority to sell, transfer and deliver the applicable Borrowed Shares.

(b) The Forward Sale Agreement between the Company and the applicable Forward Purchaser has been duly authorized, executed and delivered by such Forward Purchaser and, assuming due authorization, execution and delivery by the Company, constitutes a legal, valid and binding obligation of such Forward Purchaser, enforceable against such Forward Purchaser in accordance with its terms, except to the extent that such enforceability may be limited by applicable bankruptcy, insolvency, reorganization or other similar laws relating to or affecting creditors’ rights and general principles of equity and except as rights to indemnity and contribution thereunder may be limited by applicable law or policies underlying such law.

(c) Such Forward Seller shall, at the Closing Date or Date of Delivery, as applicable, have the free and unqualified right to transfer any Borrowed Shares, to the extent that it is required to transfer such Borrowed Shares hereunder, free and clear of any security interest, mortgage, pledge, lien, charge, claim, equity or encumbrance of any kind; and upon delivery of such Borrowed Shares and payment of the purchase price therefor as herein contemplated, assuming each of the Underwriters has no notice of any adverse claim, each of the Underwriters shall have the free and unqualified right to transfer the Borrowed Shares purchased by it from such Forward Seller, free and clear of any security interest, mortgage, pledge, lien, charge, claim, equity or encumbrance of any kind.

3. Purchase and Sale.

(a) Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, each Forward Seller (with respect to the Underwritten Borrowed Shares) and the Company (with respect to any Company Top-Up Underwritten Shares), severally

and not jointly, agrees to sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from each Forward Seller (with respect to the Underwritten Borrowed Shares) and the Company (with respect to any Company Top-Up Underwritten Shares) the respective number of Underwritten Shares set forth in Schedule II hereto opposite its name at $109.045 per share (the “Purchase Price”). The obligations of the Forward Sellers to sell Shares under this Agreement are several and not joint. Each Forward Seller’s obligations extend solely to the respective number of Shares specified opposite its name on Schedule II.

(b) Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, each Forward Seller (with respect to any Borrowed Option Shares) and the Company (with respect to any Company Top-Up Option Shares), severally and not jointly, hereby grants an option to the several Underwriters to purchase, severally and not jointly, up to the number of Option Shares set forth in Schedule II hereto opposite its name at the Purchase Price; provided that the Purchase Price shall be reduced by an amount per share equal to any dividends or distributions paid or payable on the Underwritten Shares but not payable on such Option Shares (the “Option Purchase Price”). Said option may be exercised in whole or in part at any time from time to time on or before the 30th day after the date of the Prospectus upon written or telegraphic notice by the Representatives to the Forward Sellers and the Company setting forth the number of Option Shares as to which the several Underwriters are exercising the option and the settlement date. On each Date of Delivery, if any, each Underwriter agrees, severally and not jointly, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, to purchase, at the Option Purchase Price, the number of Option Shares that bears the same ratio to the aggregate number of Option Shares being purchased on such Date of Delivery as the number of Underwritten Shares set forth opposite the name of such Underwriter in Schedule II hereto bears to the aggregate number of Underwritten Shares being purchased by the Underwriters, subject, however, to such adjustments to eliminate any fractional Shares as the Representatives in their sole discretion shall make.

(c) If (i) any of the representations and warranties of the Company and the Operating Partnership contained in Section 1 hereof or any certificate delivered by the Company pursuant hereto are not true and correct as of the Closing Date or any Date of Delivery, as the case may be, as if made as of the Closing Date or such Date of Delivery, (ii) the Company has not performed all of the obligations required to be performed by it under this Agreement on or prior to the Closing Date or such Date of Delivery, (iii) any of the conditions set forth in Section 7 hereof have not been satisfied on or prior to the Closing Date or such Date of Delivery, (iv) this Agreement shall have been terminated pursuant to Section 11 hereof on or prior to the Closing Date or such Date of Delivery or the Closing Date or such Date of Delivery shall not have occurred, (v) any of the conditions set forth in Section 7(a) of the Forward Sale Agreements shall not have been satisfied on or prior to the Closing Date or such Date of Delivery or (vi) any of the representations and warranties of the Company contained in the Forward Sale Agreements are not true and correct as of the Closing Date or such Date of Delivery as if made as of the Closing Date or such Date of Delivery (clauses (i) through (vi), together, the “Conditions”), then each of the Forward Sellers, in its sole discretion, may elect not to borrow and deliver for sale to the Underwriters the Borrowed Shares otherwise deliverable on such date. In addition, in the event a Forward Seller determines in good faith and a commercially reasonable manner that (A) in connection with establishing its commercially reasonable hedge position such Forward Seller is unable to borrow and deliver for sale under this Agreement a number of shares of Common

Stock equal to the number of Borrowed Shares to be sold by it hereunder, or (B) it would be impracticable for such Forward Seller to do so or it would incur a stock loan cost of more than 300 basis points per annum with respect to all or any portion of such shares to do so, then, in each case, such Forward Seller shall only be required to deliver for sale to the Underwriters on the Closing Date or any Date of Delivery, as the case may be, the aggregate number of shares of Common Stock that such Forward Seller or its affiliate is able to so borrow in connection with establishing its commercially reasonable hedge position at or below such cost.

(d) If a Forward Seller elects, pursuant to Section 3(c) hereof, not to borrow and deliver for sale to the Underwriters on the Closing Date or any Date of Delivery, as the case may be, the total number of Borrowed Shares to be sold by it hereunder, such Forward Seller will use its commercially reasonable efforts to notify the Company no later than 5:00 p.m., New York City time, on the Business Day prior to the Closing Date or such Date of Delivery. Notwithstanding anything to the contrary herein, in no event will the Company be required to issue or deliver the applicable Company Shares prior to the Business Day following notice to the Company of the relevant number of Shares so deliverable in accordance with this Section 3(d).

4. Delivery and Payment.

(a) Payment for the Shares shall be made by the Underwriters to the Forward Sellers (with respect to the Borrowed Shares) or to the Company (with respect to any Company Shares) in Federal or other funds immediately available in New York City against delivery of such Shares for the respective accounts of the Underwriters at 10:00 a.m., New York City time, by causing The Depository Trust Company (“DTC”) to credit the respective accounts of the Underwriters at DTC, on September 27, 2018, or at such time on such later date not more than two Business Days after the foregoing date as the Representatives shall designate, which date and time may be postponed by agreement between the Representatives, and the Forward Sellers or the Company, as applicable, or as provided in Section 13 hereof (such date and time of delivery and payment for such Shares being herein called the “Closing Date”). Delivery of the Shares shall be made, and the Shares shall be registered in, the name of Cede & Co. as nominee of DTC, and available for checking in New York, New York at least one full Business Day prior to the Closing Date or the relevant Date of Delivery, as the case may be.

(b) Notwithstanding the provisions set forth in Section 4(a) above, if the option provided for in Section 3(b) hereof is exercised after the third Business Day prior to the Closing Date, delivery of the Option Shares shall be made to the Underwriters on the date specified by the Representatives (which shall be at least one but within two Business Days after written notice of the exercise of such option is given) for the respective accounts of the several Underwriters. Payment for any Option Shares shall be made by the Underwriters to the Forward Sellers (with respect to any Borrowed Option Shares) or the Company (with respect to any Company Top-Up Option Shares) in Federal or other funds immediately available in New York City against delivery of such Option Shares for the respective accounts of the Underwriters at 10:00 a.m., New York City time, by causing DTC to credit the respective accounts of the Underwriters at DTC on the date specified in the corresponding notice described in Section 3(b) or at such other time on the same or such later date not more than two Business Days after the foregoing date as shall be designated in writing by the Representatives. If settlement for the Option Shares occurs after the Closing Date, the Company shall deliver to the Representatives on each Date of

Delivery, and the obligation of the Underwriters to purchase the Option Shares shall be conditioned upon receipt of, supplemental opinions, certificates and letters confirming as of such date the opinions, certificates and letters delivered on the Closing Date pursuant to Section 7 hereof.

5. Offering by Underwriters. It is understood that the several Underwriters propose to offer the Shares for sale to the public as set forth in the Prospectus. The Company acknowledges and agrees that the Underwriters may offer and sell Shares to or through any affiliate of an Underwriter and that any such affiliate may offer and sell Shares purchased by it to or through any Underwriter.

6. Agreements. Each of the Company and the Operating Partnership agrees with the several Underwriters, the Forward Sellers and the Forward Purchasers that:

(a) Prior to the termination of the offering of the Shares, the Company will not file any amendment of the Registration Statement or supplement (including the Prospectus or any Preliminary Prospectus) to the Base Prospectus unless the Company has furnished the Representatives, the Forward Sellers and the Forward Purchasers a copy for their review prior to filing and will not file any such proposed amendment or supplement to which you reasonably object. The Company will cause the Prospectus, properly completed, and any supplement thereto to be filed in a form to which the Representatives, the Forward Sellers and the Forward Purchasers do not reasonably object with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to the Representatives, the Forward Sellers and the Forward Purchasers of such timely filing. The Company will promptly advise the Representatives, the Forward Sellers and the Forward Purchasers (i) when the Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b), (ii) when, prior to termination of the offering of the Shares, any amendment to the Registration Statement shall have been filed or become effective, (iii) of any request by the Commission or its staff for any amendment of the Registration Statement, or for any supplement to the Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice objecting to its use or the institution or threatening of any proceeding for that purpose and (v) of the receipt by the Company or the Operating Partnership of any notification with respect to the suspension of the qualification of the Shares for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. Each of the Company and the Operating Partnership will use its best efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its best efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b) If there occurs an event or development as a result of which the Disclosure Package, taken as a whole, would include an untrue statement of a material fact or would 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 Company will promptly notify

the Representatives, the Forward Sellers and the Forward Purchasers and will promptly amend or supplement in a manner reasonably satisfactory to the Representatives, the Forward Sellers and the Forward Purchasers, at its own expense, the Disclosure Package to eliminate or correct such untrue statement or omission and the Company shall cease to use the Disclosure Package until it is so amended or supplemented.

(c) If, at any time when a prospectus relating to the Shares is required to be delivered under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event occurs as a result of which the Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, or if it shall be necessary to amend the Registration Statement, file a new registration statement or supplement the Prospectus to comply with the Act or the Exchange Act, including in connection with use or delivery of the Prospectus, the Company promptly will (i) notify the Representatives, the Forward Sellers and the Forward Purchasers of such event, (ii) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 6, an amendment or supplement or new registration statement which will correct such statement or omission or effect such compliance, (iii) use its best efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Prospectus and (iv) supply any supplemented Prospectus to you in such quantities as you may reasonably request.

(d) As soon as practicable, but in any event not later than eighteen months after the effective date of the Registration Statement, the Company will make generally available to its security holders and to the Representatives, the Forward Sellers and the Forward Purchasers an earnings statement or statements of the Company and its subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158.

(e) The Company will furnish to the Representatives, the Forward Sellers and the Forward Purchasers and counsel for the Underwriters, the Forward Sellers and the Forward Purchasers without charge, copies (which may be electronic copies) of the Registration Statement (including exhibits thereto) and to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of each Preliminary Prospectus, Prospectus and each Issuer Free Writing Prospectus and any supplement thereto as the Representatives may reasonably request.

(f) The Company will arrange, if necessary, for the qualification of the Shares for sale under the laws of such jurisdictions as the Representatives may designate and will maintain such qualifications in effect so long as required for the distribution of the Shares; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Shares, in any jurisdiction where it is not now so subject.

(g) Neither the Company nor the Operating Partnership will, without the prior written consent of the Representatives, offer, sell, contract to sell, pledge, or otherwise dispose of (or enter into any transaction which is designed to, or would reasonably be expected to, result in the disposition of (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Company or any Affiliate of the Company or any person in privity with the Company or any Affiliate of the Company), directly or indirectly, including the filing (or participation in the filing) of a registration statement under the Act (except for a registration statement on Form S-4 relating to an acquisition of a real property company or a registration statement on Form S-8 (including any amendments or supplements thereto) in connection with shares of Common Stock authorized for issuance pursuant to the terms of any plan in effect as of the date of the Prospectus) with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any shares of Common Stock (other than the Shares), limited partnership units of the Operating Partnership, or any securities convertible into, or exercisable, or exchangeable for, any of the foregoing, or publicly announce an intention to effect any such transaction, until 45 days after the date of the Prospectus, provided, however, that the Company may (i) grant stock options, restricted stock, restricted stock units or long-term incentive Units in the Operating Partnership (“LTIP Units”) to employees, consultants or directors pursuant to the terms of a plan in effect as of the date of the Prospectus, (ii) issue Common Stock or Operating Partnership units, as applicable pursuant to: (A) the exercise, vesting, settlement, conversion or redemption, as applicable, of such options, restricted stock units and LTIP Units; (B) the redemption of Units outstanding on the date of the Prospectus, including Units issued upon conversion of LTIP Units outstanding on the date of the Prospectus; provided, that the Company will notify the Representatives promptly in writing upon receipt by the Company or the Operating Partnership of any notice of redemption with respect to such Units (other than with respect to the redemption of LTIP Units) or (C) the exercise, vesting, settlement, conversion or redemption, as applicable, of any stock options, restricted stock units or LTIP Units outstanding as of the date of the Prospectus, (iii) issue Common Stock pursuant to the Company’s dividend reinvestment plan (if any), (iv) issue Common Stock pursuant to the Company’s employee stock purchase plan (if any), (v) enter into and issue and deliver Common Stock pursuant to the Forward Sale Agreements, (vi) issue (x) Common Stock or securities convertible into or exchangeable or exercisable for shares of Common Stock in connection with other acquisitions of real property or real property companies and (y) Common Stock upon conversion or exchange of any securities issued pursuant to (vi)(x) above, (vii) file shelf registration statements (including any amendments or supplements thereto) in connection with existing contractual commitments, and (viii) issue shares of Common Stock upon the conversion of any of the Company’s perpetual preferred stock pursuant to a delisting change of control transaction.

(j) Prior to the Closing Date or Date of Delivery, as applicable, the Company shall have furnished to the Representatives, the Forward Purchasers and the Forward Sellers such further information, certificates and documents as the Representatives, the Forward Purchasers or the Forward Sellers, as applicable, may reasonably request.

(l) The Shares shall have been listed and admitted and authorized for trading on the NYSE, subject to official notice of issuance and evidence of satisfactory distribution, and satisfactory evidence of such actions shall have been provided to the Representatives.

Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing.

The documents required to be delivered by this Section 7 shall be delivered at the office of Xxxxxxx Procter LLP, counsel for the Underwriters, at 000 Xxxxxxxx Xxxxxx, Xxxxxx, Xxxxxxxxxxxxx 00000, on the Closing Date, the Execution Time and each Date of Delivery, as applicable.

8. Reimbursement of Underwriters, Forward Purchasers’ and Forward Sellers’ Expenses. If the sale of the Shares provided for herein is not consummated (i) because any condition to the obligations of the Underwriters set forth in Section 7 hereof is not satisfied, (ii) because of any termination pursuant to Section 11 hereof, or (iii) because of any refusal, inability or failure on the part of the Company or the Operating Partnership to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters severally through the Representatives, the Forward Purchasers and the Forward Sellers on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Shares.

9. Indemnification of the Underwriters, the Forward Purchaser and the Forward Seller.

(a) The Company and the Operating Partnership jointly and severally agree to indemnify and hold harmless each Underwriter, each Forward Purchaser and each Forward Seller, each of their respective directors, officers, employees, Affiliates and agents and each

person, if any, who controls any Underwriter, any Forward Purchaser or any Forward Seller within the meaning of either the Act or the Exchange Act, against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Shares as originally filed or in any amendment thereof, or in the Base Prospectus, any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agree to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company and the Operating Partnership will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives, any Forward Purchaser or any Forward Seller specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company and the Operating Partnership may otherwise have.

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company and the Operating Partnership, each of the Company’s directors, each of the Company’s officers who signs the Registration Statement, each of the Company’s and the Operating Partnership’s Affiliates, and each person, if any, who controls the Company and the Operating Partnership within the meaning of either the Act or the Exchange Act and each Forward Purchaser and Forward Seller and each person, if any, who controls any Forward Purchaser or any Forward Seller within the meaning of either the Act or the Exchange Act, to the same extent as the indemnity set forth in paragraph (a) above, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The Company and the Operating Partnership acknowledge that the following statements set forth in the Preliminary Prospectus and the Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in the Registration Statement, any Preliminary Prospectus or the Prospectus: (i) the third paragraph on the cover page related to the delivery of the Shares; (ii) the list of Underwriters under the heading “Underwriting (Conflicts of Interest)” and their respective participation in the sale of the Shares; (iii) the tenth and eleventh paragraphs of text under the heading “Underwriting (Conflicts of Interest)” related to market-making activities, stabilization, syndicate covering transactions, penalty bids and maximum discounts and that no information has been furnished by the Forward Purchasers or the Forward Sellers for such inclusion.

(c) 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 the indemnifying party under this Section 9, notify the indemnifying party in

writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel (including local counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded 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, (iii) 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 the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. Notwithstanding the foregoing, it is understood that the Company and the Operating Partnership shall, in connection with any action or related actions in the same jurisdiction, bear the fees, costs and expenses of only one such separate counsel (in addition to any local counsel) for all the Underwriters, Forward Sellers and Forward Purchasers and the directors, officers, employees and agents of the Underwriters, Forward Sellers and Forward Purchasers and each person who controls any Underwriter, Forward Seller or Forward Purchaser within the meaning of either the Act or the Exchange Act (collectively, the “Specified Indemnified Parties”), provided, however, the Company and the Operating Partnership shall bear the fees, costs and expenses of more than one separate counsel (in addition to any local counsel) if the use of only one separate counsel for all the Specified Indemnified Parties would present such counsel with a conflict of interest with respect to one or more of the Specified Indemnified Parties. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (A) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (B) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 9 is unavailable to or insufficient to hold harmless an indemnified party for any reason, then each indemnifying party under such paragraph in lieu of indemnifying such indemnified person

thereunder, shall agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which such indemnified party may be subject in such proportion as is appropriate to reflect the relative benefits received by the indemnifying person on the one hand and by the indemnified person on the other from the offering of the Shares; provided, however, that (i) in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Shares) be responsible for any amount in excess of the underwriting discount or commission, as the case may be, applicable to the Shares purchased by such Underwriter hereunder and (ii) no Forward Seller shall be required to contribute an amount in excess of the aggregate Spread (as defined in the applicable Forward Sale Agreement) retained by such Forward Purchaser under the applicable Forward Sale Agreement. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the indemnifying parties severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the indemnified party on the one hand and of the indemnifying party on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the parties shall be deemed to be the same respective proportions as (x) in the case of the Company and the Operating Partnership, the net proceeds (before deducting expenses) received by the Company (which proceeds shall include the proceeds that would be received by the Company pursuant to the Forward Sale Agreements assuming Physical Settlement (as such term is defined in the Forward Sale Agreements) of the Forward Sale Agreements on the Effective Date (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 Sellers, the 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 Sellers, in each case as set forth in the applicable Forward Sale Agreement. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company, the Operating Partnership, the Underwriters, the Forward Purchasers or the Forward Sellers, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. 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 were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 9, each person who controls an Underwriter, a Forward Seller or a Forward Purchaser within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter, a Forward Seller or a Forward Purchaser shall have the same rights to contribution as such Underwriter, Forward Seller or Forward Purchaser and each person who controls the Company or the Operating Partnership within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to

contribution as the Company and the Operating Partnership, subject in each case to the applicable terms and conditions of this paragraph (d). The Underwriters’ respective obligations to contribute pursuant to this paragraph (d) are several in proportion to the number of Securities set forth opposite their respective names in Schedule II hereto and not joint.

10. Default by an Underwriter. If, on the Closing Date or a Date of Delivery, any one or more Underwriters shall fail to purchase and pay for any of the Shares agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of Shares set forth opposite their names in Schedule II hereto bears to the aggregate amount of Shares set forth opposite the names of all the remaining Underwriters) the Shares which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate amount of Shares which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Shares set forth in Schedule II hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Shares, and if such nondefaulting Underwriters do not purchase all the Shares, this Agreement will terminate without liability to any nondefaulting Underwriter, any Forward Seller, any Forward Purchaser, the Company or the Operating Partnership. In the event of a default by any Underwriter as set forth in this Section 10, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement and the Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company, the Operating Partnership, any Forward Seller, any Forward Purchaser and any nondefaulting Underwriter for damages occasioned by its default hereunder.

11. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company, Forward Purchasers and Forward Sellers prior to delivery of and payment for the Shares, if at any time prior to such time (i) trading in the Company’s Common Stock shall have been suspended by the Commission or the NYSE or trading in securities generally on the NYSE, as applicable, shall have been suspended or limited or minimum prices shall have been established on such exchange, (ii) a banking moratorium shall have been declared either by federal or New York state authorities, (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Shares as contemplated by the Prospectus (exclusive of any supplement thereto) , or (iv) there shall have occurred a material disruption in commercial banking or securities settlement or clearance services.

12. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company, the Operating Partnership or officers of the Company or the Operating Partnership, of the Forward Purchasers, the Forward Sellers or of the Underwriters 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 Underwriter, any Forward Purchaser, any Forward Seller, the Company, the Operating

Partnership or any of the indemnified persons referred to in Section 9 hereof, and will survive delivery of and payment for the Shares. The provisions of Sections 8 and 9 hereof shall survive the termination or cancellation of this Agreement.

13. Additional Issuance and Sale by the Company.

In connection with any such issuance and sale by the Company, the Company or the Representatives shall have the right to postpone the Closing Date or Date of Delivery, as the case may be, for a period not exceeding one Business Day in order to effect any required changes in any documents or arrangements. The shares of Common Stock sold by the Company to the Underwriters pursuant to this Section 13(a): (i) in lieu of any Underwritten Borrowed Shares are referred to herein as the “Company Top-Up Underwritten Shares” and (ii) in lieu of any Borrowed Option Shares are referred to herein as the “Company Top-Up Option Shares.”

(b) Neither any of the Forward Purchasers nor any of the Forward Sellers shall have any liability whatsoever for any Borrowed Shares that such Forward Seller does not deliver and sell to the Underwriters or any other party if (i) all of the Conditions are not satisfied on or prior to the Closing Date or Date of Delivery, as applicable, and such Forward Seller elects, pursuant to Section 3(c) hereof not to deliver and sell to the Underwriters the Borrowed Shares to be sold by it, (ii) such Forward Seller or an affiliate thereof is unable, after using commercially reasonable efforts, to borrow and deliver for sale under this Agreement on the Closing Date or Date of Delivery, as applicable, a number of shares of Common Stock equal to the number of the Borrowed Shares to be sold by it or (iii) in the applicable Forward Purchaser’s commercially reasonable judgment, such Forward Seller or its affiliate would incur a stock loan cost of more than 300 basis points per annum to borrow and deliver for sale under this Agreement the total number of Borrowed Shares to be sold by it.
