Ladies and Gentlemen:

Curbline Properties LP, a Delaware limited partnership (the “Issuer”), and Curbline Properties Corp., a Maryland corporation (the “Parent,” and together with the Issuer, the “Constituent Companies” and individually, a “Constituent Company”), jointly and severally agree with each of the Purchasers as follows:

Section 1. Authorization of Notes.

The Issuer will authorize the issue and sale of $150,000,000 aggregate principal amount of its Guaranteed Senior Notes, of which $100,000,000 aggregate principal amount shall be its 5.58% Guaranteed Senior Notes, Series 2025-A, due September 3, 2030 (the “Series A Notes”) and $50,000,000 aggregate principal amount shall be its 5.87% Guaranteed Senior Notes, Series 2025-B, due September 3, 2032 (the “Series B Notes”; the Series A Notes and the Series B Notes are hereinafter referred to collectively as the “Notes”). The Series A Notes and the Series B Notes shall be substantially in the forms set out in Schedule 1(a) and Schedule 1(b), respectively. Certain capitalized and other terms used in this Agreement are defined in Schedule A and, for purposes of this Agreement, the rules of construction set forth in Section 23.4 shall govern.

Section 2. Sale and Purchase of Notes.

Section 2.1. Sale and Purchase of Notes. Subject to the terms and conditions of this Agreement, the Issuer will issue and sell to each Purchaser and each Purchaser will purchase from the Issuer, at the Closing provided for in Section 3, Notes in the principal amount and of the series specified opposite such Purchaser’s name in the Purchaser Schedule at the purchase price of 100% of the principal amount thereof. The Purchasers’ obligations hereunder are several and not joint obligations and no Purchaser shall have any liability to any Person for the performance or non-performance of any obligation by any other Purchaser hereunder.

Section 2.2. Guaranty. The obligations of the Issuer hereunder and under the Notes are unconditionally and irrevocably guaranteed by the Parent pursuant to Section 13 (the “Parent Guaranty”).

(a) The Parent and its Subsidiaries have filed all tax returns that are required to have been filed in any jurisdiction, and have paid all taxes shown to be due and payable on such returns and all other taxes and assessments levied upon them or their properties, assets, income or franchises, to the extent such taxes and assessments have become due and payable and before they have become delinquent, except for the filing of any such tax returns or the payment of any such taxes and assessments (a) the failure of which would not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect or (b) the amount, applicability or validity of which is currently being contested in good faith by appropriate proceedings and with respect to which the Parent or a Subsidiary, as the case may be, has established adequate reserves in accordance with GAAP. Neither Constituent Company knows of any basis for any other tax or assessment that would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The charges, accruals and reserves on the books of the Parent and its Subsidiaries in respect of U.S. federal, state or other taxes for all fiscal periods are adequate. On the Execution Date, neither the Parent nor any of its Subsidiaries is under audit by the Internal Revenue Service for any of its previous tax years.

Schedule 5.10, as such Schedule may have been updated pursuant to Section 4.1, is a complete and correct listing of all Unencumbered Assets.

Except as would not, individually or in the aggregate, result in Material liability, (1) neither the Parent nor any ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA and (2) neither the Parent nor any Subsidiary has incurred any liability pursuant to the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined in section 3 of ERISA). No event, transaction or condition has occurred or exists that would, individually or in the aggregate, reasonably be expected to result in the incurrence of any such liability by the Parent or any

ERISA Affiliate, or in the imposition of any Lien on any of the rights, properties or assets of the Parent or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to section 430(k) of the Code or to any such penalty or excise tax provisions under the Code or section 4068 of ERISA or by the granting of a security interest in connection with the amendment of a Plan, other than such liabilities or Liens as would not be individually or in the aggregate Material.

Section 5.13. Private Offering by the Constituent Companies. Neither Constituent Company or anyone acting on its behalf has offered the Notes, the Parent Guaranty or any similar Securities for sale to, or solicited any offer to buy the Notes, the Parent Guaranty or any similar Securities from, or otherwise approached or negotiated in respect thereof with, any Person other than the Purchasers and not more than five other Institutional Investors, each of which has been offered the Notes and the Parent Guaranty at a private sale for investment. Neither Constituent Company or anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of the Notes or the delivery of the Parent Guaranty to the registration requirements

of section 5 of the Securities Act or to the registration requirements of any Securities or blue-sky laws of any applicable jurisdiction.

Section 5.14. Use of Proceeds; Margin Regulations. The Issuer will apply the proceeds of the sale of the Notes as set forth in the Investor Presentation. No part of the proceeds from the sale of the Notes hereunder will be used, directly or indirectly, for the purpose of buying or carrying any margin stock within the meaning of Regulation U of the Board of Governors of the Federal Reserve System (12 CFR 221), or for the purpose of buying or carrying or trading in any Securities under such circumstances as to involve the Issuer in a violation of Regulation X of said Board (12 CFR 224) or to involve any broker or dealer in a violation of Regulation T of said Board (12 CFR 220). Margin stock does not constitute more than 10% of the value of the consolidated assets of the Issuer and its Subsidiaries and the Issuer does not have any present intention that margin stock will constitute more than 10% of the value of such assets. As used in this Section, the terms “margin stock” and “purpose of buying or carrying” shall have the meanings assigned to them in said Regulation U.

Section 5.15. Existing Indebtedness; Future Liens.

Section 8. Payment and Prepayment of the Notes.

Section 8.1. Maturity. As provided therein, the entire unpaid principal balance of each Note shall be due and payable on the Maturity Date thereof.

Section 8.2. Optional Prepayments with Make-Whole Amount. The Issuer may, at its option, upon notice as provided below, prepay at any time all, or from time to time any part of, the Notes, in an amount not less than 5% of the aggregate principal amount of the Notes then outstanding in the case of a partial prepayment, at 100% of the principal amount so prepaid, and the Make-Whole Amount determined for the prepayment date with respect to such principal amount. The Issuer will give each holder of Notes written notice of each optional prepayment under this Section 8.2 not less than 10 days and not more than 60 days prior to the date fixed for such prepayment unless the Issuer and the Required Holders agree to another time period pursuant to Section 18. Each such notice shall specify such date (which shall be a Business Day), the aggregate principal amount of the Notes to be prepaid on such date, the principal amount of each Note held by such holder to be prepaid (determined in accordance with Section 8.3), and the interest to be paid on the prepayment date with respect to such principal amount being prepaid, and shall be accompanied by a certificate of a Senior Financial Officer of the Issuer as to the estimated Make-Whole Amount due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment), setting forth the details of such computation. Two Business Days prior to such prepayment, the Issuer shall deliver to each holder of Notes a certificate of a Senior Financial Officer of the Issuer specifying the calculation of such Make-Whole Amount as of the specified prepayment date.

Section 8.3. Allocation of Partial Prepayments. In the case of each partial prepayment of the Notes pursuant to Section 8.2, the principal amount of the Notes to be prepaid shall be allocated among all of the Notes at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for prepayment.

Section 8.4. Maturity; Surrender, Etc. In the case of each prepayment of Notes pursuant to this Section 8, the principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment, together with interest on such principal amount accrued to such date and the applicable Make-Whole Amount, if any. From and after such date, unless the Issuer shall fail to pay such principal amount when so due and payable, together with the interest and Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be surrendered to the Issuer and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note.

Section 8.5. Purchase of Notes. The Issuer will not, and will not permit any of its Affiliates to, purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except (a) upon the payment or prepayment of the Notes in accordance with this Agreement and the Notes or (b) pursuant to an offer to purchase made by the Issuer or one of its Affiliates pro rata to the holders of all Notes at the time outstanding upon the same terms and conditions. Any such offer shall provide each holder with sufficient information to enable it to make an informed decision with respect to such offer, and shall remain open for at least 10 Business Days. If the holders of more than 25% of the principal amount of the Notes then outstanding accept such offer, the Issuer shall promptly notify the remaining holders of such fact and the expiration date for the acceptance by holders of Notes of such offer shall be extended by the number of days necessary to give each such remaining holder at least 10 Business Days from its receipt of such notice to accept such offer. The Issuer will promptly cancel all Notes acquired by it or any of its Affiliates pursuant to any payment, prepayment or purchase of Notes pursuant to this Agreement and no Notes may be issued in substitution or exchange for any such Notes.

Section 8.6. Make-Whole Amount.

The term “Make-Whole Amount” means, with respect to any Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings: “Called Principal” means, with respect to any Note, the principal of such Note that is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

“Discounted Value” means, with respect to the Called Principal of any Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal.

“Reinvestment Yield” means, with respect to the Called Principal of any Note, the sum of (a) 0.50% plus (b) the yield to maturity implied by the “Ask Yield(s)” reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on-the-run U.S. Treasury securities (“Reported”) having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there are no such U.S. Treasury securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by (1) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (2) interpolating linearly between the “Ask Yields” Reported for the applicable most recently issued actively traded on-the-run U.S. Treasury securities with the maturities (i) closest to and greater than such Remaining Average Life and (ii) closest to and less than such Remaining Average Life. The Reinvestment

Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then “Reinvestment Yield” means, with respect to the Called Principal of any Note, the sum of (x) 0.50% plus (y) the yield to maturity implied by the U.S. Treasury constant maturity yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for the U.S. Treasury constant maturity having a term equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity will be determined by interpolating linearly between (A) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (B) the U.S. Treasury constant maturity so reported with the term closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

“Remaining Average Life” means, with respect to any Called Principal, the number of years obtained by dividing (a) such Called Principal into (b) the sum of the products obtained by multiplying (1) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (2) the number of years, computed on the basis of a 360-day year comprised of twelve 30-day months and calculated to two decimal places, that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2 or Section 12.1.

“Settlement Date” means, with respect to the Called Principal of any Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

Section 8.7. Offer to Prepay Notes in the Event of a Change in Control.

(a) Notice of Change in Control. The Constituent Companies will, within 10 Business Days after any Responsible Officer of either thereof has knowledge of the occurrence of any Change in Control give written notice of such Change in Control to each holder of Notes and such notice shall contain and constitute an offer by the Issuer to prepay Notes as described in Section 8.7(b) and shall be accompanied by the certificate described in Section 8.7(e).

(b) Offer to Prepay Notes. The offer to prepay Notes contemplated by Section 8.7(a) shall be an offer to prepay, in accordance with and subject to this Section 8.7, all, but not less than all, Notes held by each holder on a date specified in such offer (the “Change in Control Proposed Prepayment Date”), which date shall be a Business Day not less than 30 days and not more than 60 days after the date of such offer (or if the Change in Control Proposed Prepayment Date shall not be specified in such offer, the Change in Control Proposed Prepayment Date shall be the Business Day nearest to the 45th day after the date of such offer).

(c) Acceptance; Rejection. A holder of Notes may accept or reject the offer to prepay made pursuant to this Section 8.7 by causing a notice of such acceptance or rejection to be delivered to the Issuer at least 20 days prior to the Change in Control Proposed Prepayment Date. A failure by a holder of Notes to so respond to an offer to prepay made pursuant to this Section 8.7 shall be deemed to constitute a rejection of such offer by such holder.

(d) Prepayment. Prepayment of the Notes to be prepaid pursuant to this Section 8.7 shall be at 100% of the principal amount of such Notes but without any Make-Whole Amount. The prepayment shall be made on the Change in Control Proposed Prepayment Date.

(e) Officer’s Certificate. Each offer to prepay the Notes pursuant to this Section 8.7 shall be accompanied by a certificate, executed by a Senior Financial Officer of the Issuer and dated the date of such offer, specifying (1) the Change in Control Proposed Prepayment Date, (2) that such offer is made pursuant to this Section 8.7 and that failure by a holder to respond to such offer by the deadline established in Section 8.7(c) shall result in such offer to such holder being deemed rejected, (3) the principal amount of each Note offered to be prepaid, (4) the interest that would be due on each Note offered to be prepaid, accrued to the Change in Control Proposed Prepayment Date, (5) that the conditions of this Section 8.7 have been fulfilled and (6) in reasonable detail, the nature and date of the Change in Control.

(f) Change in Control Defined. “Change in Control” means any “person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934 (the “Exchange Act”)) is or becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act, except that a Person will be deemed to have “beneficial ownership” of all Securities that such Person has the right to acquire, whether such right is exercisable immediately or only after the passage of time), directly or indirectly, of more than 40% of the total voting power of the then issued and outstanding voting Capital Stock of the Parent.

Section 8.8. Payments Due on Non-Business Days. Anything in this Agreement or the Notes to the contrary notwithstanding, (a) except as set forth in clause (b), any payment of interest on any Note that is due on a date that is not a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day; and (b) any payment of principal of or

Make-Whole Amount on any Note (including principal due on the Maturity Date of such Note) that is due on a date that is not a Business Day shall be made on the next succeeding Business Day and shall include the additional days elapsed in the computation of interest payable on such next succeeding Business Day.

Section 9. Affirmative Covenants

From the Execution Date until the Closing and thereafter, so long as any of the Notes are outstanding, the Constituent Companies covenant that:

Section 9.1. Compliance with Laws. Without limiting Section 10.4, each Constituent Company will, and will cause each of its Subsidiaries to, comply with all laws, ordinances or governmental rules or regulations to which each of them is subject (including ERISA, Environmental Laws, the USA PATRIOT Act and the other laws and regulations that are referred to in Section 5.16) and will obtain and maintain in effect all licenses, certificates, permits, franchises and other governmental authorizations necessary to the ownership of their respective properties or to the conduct of their respective businesses, in each case to the extent necessary to ensure that non-compliance with such laws, ordinances or governmental rules or regulations or failures to obtain or maintain in effect such licenses, certificates, permits, franchises and other governmental authorizations would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

Section 9.2. Insurance. Each Constituent Company will, and will cause each of its Subsidiaries to, maintain, with financially sound and reputable insurers, insurance with respect to their respective properties and businesses against such casualties and contingencies, of such types, on such terms and in such amounts (including deductibles, co-insurance and self-insurance, if adequate reserves are maintained with respect thereto) as is customary in the case of entities of established reputations engaged in the same or a similar business and similarly situated.

Section 9.3. Maintenance of Properties. Each Constituent Company will, and will cause each of its Subsidiaries to, maintain and keep, or cause to be maintained and kept, their respective Projects and properties, reasonably necessary for the continuous operation of the Projects and properties, in good repair, working order and condition (other than (a) ordinary wear and tear, (b) condemnation, casualty or similar events, or (c) where the failure to do so would not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect), provided that this Section 9.3 shall not prevent either Constituent Company or any Subsidiary from discontinuing the operation and the maintenance of any of its Projects or properties if such discontinuance is desirable in the conduct of its business and the Constituent Companies have concluded that such discontinuance would not, individually or in the aggregate. reasonably be expected to have a Material Adverse Effect.

Section 9.4. Payment of Taxes and Claims. Each Constituent Company will, and will cause each of its Subsidiaries to, file all tax returns required to be filed in any jurisdiction and to pay and discharge all taxes shown to be due and payable on such returns and all other taxes, assessments, governmental charges, or levies imposed on them or any of their properties, assets, income or franchises, to the extent the same have become due and payable and before they have become delinquent and all claims for which sums have become due and payable that have or might

become a Lien on properties or assets of either Constituent Company or any Subsidiary, provided that neither Constituent Company or any Subsidiary need pay any such tax, assessment, charge, levy or claim if (a) the amount, applicability or validity thereof is contested by such Constituent Company or such Subsidiary on a timely basis in good faith and in appropriate proceedings, and a Constituent Company or a Subsidiary has established adequate reserves therefor in accordance with GAAP on the books of such Constituent Company or such Subsidiary or (b) the nonpayment of all such taxes, assessments, charges, levies and claims would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

Section 9.5. Corporate Existence, Etc. Subject to Section 10.2, each Constituent Company will at all times preserve and keep its limited partnership or corporate existence in full force and effect. Subject to Sections 10.2, each Constituent Company will at all times preserve and keep in full force and effect the corporate or other legal entity existence of each of its Subsidiaries (unless merged into a Constituent Company or a Wholly-Owned Subsidiary) and all rights and franchises of each Constituent Company and its Subsidiaries unless, in the good faith judgment of the Constituent Companies, the termination of or failure to preserve and keep in full force and effect such corporate or other legal entity existence, right or franchise would not, individually or in the aggregate, have a Material Adverse Effect.

Section 9.6. Books and Records. Each Constituent Company will, and will cause each of its Subsidiaries to, maintain proper books of record and account in conformity with GAAP and all applicable requirements of any Governmental Authority having legal or regulatory jurisdiction over such Constituent Company or such Subsidiary, as the case may be. Each Constituent Company will, and will cause each of its Subsidiaries to, keep books, records and accounts which, in reasonable detail, accurately reflect all transactions and dispositions of assets.

(1) enter into an agreement in form and substance satisfactory to the Required Holders providing for the guaranty by such Subsidiary, on a joint and several basis with all other such Subsidiaries, of (i) the prompt payment in full when due of all amounts payable by the Issuer pursuant to the Notes (whether for principal, interest, Make-Whole Amount, if any, or otherwise) and this Agreement, including all indemnities, fees and expenses payable by the Constituent Companies hereunder and (ii) the prompt, full and faithful performance, observance and discharge by the Constituent Companies of each and every covenant, agreement, undertaking and provision required pursuant to the Notes or this Agreement to be performed, observed or discharged by them (a “Subsidiary Guaranty”); and

(2) deliver the following to each holder of a Note:

(i) an executed counterpart of such Subsidiary Guaranty;

(ii) a certificate signed by an authorized responsible officer of such Subsidiary containing representations and warranties on behalf of such Subsidiary to the same effect, mutatis mutandis, as those contained in Sections 5.1(b), 5.2(b), 5.6(b) and 5.7(b) of this Agreement (but with respect to such Subsidiary and such Subsidiary Guaranty rather than the Parent and this Agreement);

(iii) all documents as may be reasonably requested by the Required Holders to evidence the due organization, continuing existence and, where applicable, good standing of such Subsidiary and the due authorization by all requisite action on the part of such Subsidiary of the execution and delivery of such Subsidiary Guaranty and the performance by such Subsidiary of its obligations thereunder; and

such Subsidiary Guarantor has been released and discharged (or will be released and discharged concurrently with the release of such Subsidiary Guarantor under such Subsidiary Guaranty) under such Material Credit Facility, (2) at the time of, and after giving effect to, such release and discharge, no Default or Event of Default shall have occurred and be continuing, (3) no amount is then due and payable under any Subsidiary Guaranty, (4) if in connection with such Subsidiary Guarantor being released and discharged under any Material Credit Facility, any fee or other form of consideration is given to any holder of Indebtedness under such Material Credit Facility for such release, the holders of the Notes shall receive equivalent consideration substantially concurrently therewith and (5) each holder shall have received a certificate of a Responsible Officer of the Parent certifying as to the matters set forth in clauses (1) through (4).

Although it will not be a Default or an Event of Default if the Constituent Companies fail to comply with any provision of Section 9 on or after the Execution Date and prior to the Closing, if such a failure occurs and is continuing, then any of the Purchasers may elect not to purchase the Notes on the date of the Closing that is specified in Section 3.

Section 10.2. Merger, Consolidation, Etc.

(a) Neither Constituent Company will, nor will it permit any of its Subsidiaries to, (1) merge, consolidate, reorganize or liquidate, in each case, impacting the Parent, the Issuer, any Subsidiary Guarantor, or all or substantially all of the Projects of the Parent and its Wholly-Owned Subsidiaries taken as a whole, or (2) transfer or otherwise dispose of all or substantially all of the Projects of the Parent and its Wholly-Owned Subsidiaries, taken as a whole, except for, in each case, (i) such transactions that occur between the Parent and the Issuer, transactions between or among Wholly-Owned Subsidiaries or transactions between or among the Parent, the Issuer and/or one or more Wholly-Owned Subsidiaries, (ii) mergers solely to change the jurisdiction of organization of a Subsidiary (other than the Issuer), (iii) transactions in which a Subsidiary or the Issuer is the survivor and (iv) as otherwise approved in advance by the Required Holders; provided, however, that in each case (A) if the Parent or the Issuer is a party to any such transaction, the Parent or the Issuer, as applicable, shall survive such transaction and (B) if a Subsidiary Guarantor is a party to any such transaction, such Subsidiary Guarantor shall either survive such transaction or be released from its obligations under its Subsidiary Guaranty in accordance with Section 9.9(b). Neither Constituent Company will reorganize itself under the laws of any jurisdiction other than the United States, any state thereof or the District of Columbia.

(b) Without the prior written consent of the Required Holders, neither Constituent Company will, nor will it permit any of its Subsidiaries to, sell, transfer or otherwise dispose of any of their respective Properties or Projects if a Default has occurred and is continuing.

Section 10.3. Line of Business. Neither Constituent Company will, nor will it permit any of its Subsidiaries to, undertake any business other than the acquisition, development, ownership, management, operation, leasing and disposition of retail, office, residential or industrial properties, ancillary businesses reasonably related to such types of properties, businesses incidental thereto and any other investments or dispositions not prohibited by this Agreement.

Section 10.4. Economic Sanctions, Etc. Neither Constituent Company will, nor will it permit any Controlled Entity to (a) become (including by virtue of being owned or controlled by a Blocked Person), own or control a Blocked Person or (b) directly or indirectly have any investment in or engage in any dealing or transaction (including any investment, dealing or transaction involving the proceeds of the Notes) with any Person if such investment, dealing or transaction (1) would cause any Purchaser or holder or any affiliate of such Purchaser or holder to be in violation of, or subject to sanctions under, any law or regulation applicable to such holder, or (2) is prohibited by or subject to sanctions under any U.S. Economic Sanctions Laws.

Section 10.6. Financial Covenants. The Parent on a consolidated basis with its Subsidiaries will not permit, as of the last day of any fiscal quarter ending after the Execution Date (provided that only the Parent’s Ownership Share of the financial attributes of a non-Wholly-Owned Subsidiary shall be considered when determining compliance with the following covenants):

(a) Consolidated Outstanding Indebtedness to exceed 60% of Consolidated Market Value; provided that, for the purpose of calculating such ratio, Consolidated Outstanding Indebtedness shall be adjusted by deducting the amount of Restricted Cash Collateral with respect to any Consolidated Outstanding Indebtedness included in such calculation;

(b) Consolidated Secured Indebtedness to exceed 35% of Consolidated Market Value; provided that, for the purpose of calculating such ratio, Consolidated Secured Indebtedness shall be adjusted by deducting the amount of Restricted Cash Collateral with respect to any Consolidated Secured Indebtedness included in such calculation;

(c) the Value of Unencumbered Assets to be less than 1.67 times the Consolidated Unsecured Indebtedness; provided that, for the purpose of calculating such ratio, Consolidated Unsecured Indebtedness shall be adjusted by deducting the amount of Restricted Cash Collateral with respect to any Consolidated Unsecured Indebtedness included in such calculation;

(e) Unencumbered Adjusted NOI to be less than 1.75 times Consolidated Unsecured Interest Expense, based on the most recently ended four fiscal quarters.

Notwithstanding the foregoing or the applicable definitions used in this Section 10.6, in determining the financial covenants, for the calculations pursuant to this Section 10.6 on June 30, 2025, the components of such calculations if not fixed shall be determined for the three fiscal quarter period ending on such date multiplied by 4/3.

Anything in clause (b) of this Section 10.6 to the contrary notwithstanding, the Constituent Companies will not, and will not permit any Subsidiary to, secure any Indebtedness outstanding under or pursuant to any Material Credit Facility unless and until the Notes (and any Guarantee Obligation delivered in connection therewith) shall concurrently be secured equally and ratably with such Indebtedness pursuant to documentation reasonably acceptable to the Required Holders in substance and in form, including an intercreditor agreement and opinions of counsel to the Constituent Companies and/or any such Subsidiary, as the case may be, from counsel that is reasonably acceptable to the Required Holders.

Notwithstanding anything herein to the contrary, all calculations to determine compliance with the above financial covenants shall exclude values, including Indebtedness, assets, liabilities, income, revenues and expenses, attributable to any Project owned by a member of the Consolidated Group or an Investment Affiliate if (1) a receiver, custodian, trustee, examiner, liquidator or similar official has been appointed for such Project and (2) the Indebtedness encumbering or attributable to such Project is Nonrecourse Indebtedness, and (3) no recourse event has been triggered and is continuing under any guaranty or indemnity agreement of a member of the Consolidated Group or an Investment Affiliate related to such Nonrecourse Indebtedness as a result of any of the events described in clause (1) of this paragraph which has not been waived in writing by the holder of such Nonrecourse Indebtedness or with respect to which the holder of such Nonrecourse Indebtedness has not otherwise agreed in writing to forbear from enforcing or exercising its rights under such guaranty or indemnity agreement (but only for so long as such waiver or forbearance continues), provided, further, however, that in no event shall this paragraph be deemed or construed to exclude any Project, member of the Consolidated Group or Investment Affiliate from any covenants, requirements or obligations of such entities set forth in any other Section of this Agreement. The aggregate amount of such members of the Consolidated Group and Investment Affiliates’ pro rata share of all such Nonrecourse Indebtedness encumbering or attributable to all such Projects excluded from calculations to determine compliance with the above financial covenants shall not exceed $150,000,000.

Section 11. Events of Default.

An “Event of Default” shall exist if any of the following conditions or events shall occur and be continuing:

The Issuer acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Issuer (except as herein specifically provided for) and that the provision for payment of a Make-Whole Amount, if any, by the Issuer in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances.

Section 12.2. Other Remedies.

No right, power or remedy conferred by this Agreement, any Subsidiary Guaranty or any Note upon any holder thereof shall be exclusive of any other right, power or remedy referred to herein or therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Constituent Companies under Section 16, the Issuer will pay to the holder of each Note on demand such further amount as shall be sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection under this Section 12, including reasonable attorneys’ fees, expenses and disbursements.

Section 13. Guaranty.

Section 13.1. The Guaranty. The Parent hereby absolutely, unconditionally and irrevocably guarantees, as primary obligor and not merely as surety, to each holder of a Note (a) the full and punctual payment when due, whether at maturity, by acceleration, by redemption or otherwise, of the principal of, Make-Whole Amount, if any, and interest (including any interest accruing after the commencement of any proceeding in bankruptcy and any additional interest that would accrue but for the commencement of such proceeding) on the Notes and all other obligations of the Issuer under this Agreement and (b) the full and prompt performance and observance by the Issuer of each and all of the obligations, covenants and agreements required to be performed or observed by the Issuer under the terms of this Agreement and the Notes (all the foregoing being hereinafter collectively called the “Obligations”). The Parent further agrees that the Obligations may be extended or renewed, in whole or in part, without notice or further assent from it, and that it shall remain bound under this Section 13 notwithstanding any extension or renewal of any Obligation.

Section 13.2. Waiver of Defenses. The Parent waives presentation to, demand of payment from and protest to the Issuer of any of the Obligations and also waives notice of protest for nonpayment. The Parent waives notice of any default under this Agreement, the Notes or the other Obligations. The obligation of the Parent hereunder shall not be affected by (a) the failure of any holder of a Note to assert any claim or demand or to enforce any right or remedy against the Issuer or any other Person (including any Subsidiary Guarantor) under this Agreement, the Notes, any Subsidiary Guaranty or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Agreement, the Notes, any Subsidiary Guaranty or any other agreement; (d) the acceptance of any security or guaranty (including any Subsidiary Guaranty) by any holder of a Note for the Obligations or any of them; (e) the release of any security or guaranty (including any Subsidiary Guaranty) held by any holder of a Note for the Obligations or any of them; (f) the release of the Issuer, any Subsidiary Guarantor or any other Person from its liability with respect to the Obligations; (g) any act or failure to act with regard to the Obligations; (h) the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all the assets, marshalling of assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization or arrangement under bankruptcy or similar laws, composition with creditors or readjustment of, or other similar procedure affecting the Issuer, any Subsidiary Guarantor or any other Person or any of the assets of any of them, or any allegation or contest of the validity of this Agreement, the Notes, any Subsidiary Guaranty or any other agreement or the disaffirmance of this Agreement or the Notes or any Subsidiary Guaranty or any other agreement in any such proceeding; (i) the invalidity or unenforceability of this Agreement, the Notes, any

Subsidiary Guaranty or any other agreement; (j) the impossibility or illegality of performance on the part of the Issuer, any Subsidiary Guarantor or any other Person of its obligations under the Notes, this Agreement, any Subsidiary Guaranty or any other instrument or agreement; (k) in respect of the Issuer, any Subsidiary Guarantor or any other Person, any change of circumstances, whether or not foreseen or foreseeable, whether or not imputable to the Issuer, any Subsidiary Guarantor or any other Person, or other impossibility of performance through fire, explosion, accident, labor disturbance, floods, droughts, pandemics, embargoes, wars (whether or not declared), acts of terrorists, civil commotions, acts of God or the public enemy, delays or failures of suppliers or carriers, inability to obtain materials, action of any Governmental Authority, change of law or any other causes affecting performance, or other force majeure, whether or not beyond the control of the Issuer, any Subsidiary Guarantor or any other Person and whether or not of the kind above specified; or (l) any change in the ownership of the Issuer.

It being understood that the specific enumeration of the above-mentioned acts, failures or omissions shall not be deemed to exclude any other acts, failures or omissions, though not specifically mentioned above, it being the purpose and intent of this Section 13.2 that the obligations of the Parent shall be absolute, unconditional and irrevocable and shall not be discharged, impaired or varied except by the payment of the Obligations and then only to the extent of such payment.

Section 13.3. Guaranty of Payment. The Parent further agrees that the guaranty contained in this Section 13 constitutes a guaranty of payment when due (and not a guaranty of collection) and waives any right to require that any resort be had by any holder of a Note to any other Person or to any security held for payment of the Obligations.

Section 13.4. Guaranty Unconditional. The obligations of the Parent hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of the Parent herein shall not be discharged or impaired or otherwise affected by the failure of any holder of a Note to assert any claim or demand or to enforce any remedy under this Agreement, the Notes, any Subsidiary Guaranty or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of the Parent or would otherwise operate as a discharge of the Parent as a matter of law or equity.

Section 13.5. Reinstatement. The Parent further agrees that the guaranty herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored by any holder of a Note upon the bankruptcy or reorganization of the Issuer or otherwise.

Section 13.6. Payment on Demand. In furtherance of the foregoing and not in limitation of any other right which any holder of a Note has at law or in equity against the Parent by virtue hereof, upon the failure of the Issuer to pay any of the Obligations when and as the same shall

become due, whether at maturity, by acceleration, by redemption or otherwise, the Parent hereby promises to and shall, upon receipt of written demand by any holder of a Note, forthwith pay, or cause to be paid, in cash, to the holders an amount equal to the sum of (a) the unpaid amount of such Obligations then due and owing and (b) accrued and unpaid interest on such Obligations then due and owing.

The Parent acknowledges and agrees that repeated and successive demands may be made and recoveries may be had hereunder as and when, from time to time, the Issuer shall default under the terms of a Note or this Agreement and that notwithstanding recovery hereunder for or in respect of any given Default or Event of Default, the guaranty contained in this Section 13 shall remain in full force and effect and shall apply to each and every subsequent Default or Event of Default.

Section 13.7. Stay of Acceleration. The Parent further agrees that, as between itself, on the one hand, and the holders of the Notes, on the other hand, (a) the maturity of the Obligations guaranteed hereby may be accelerated as provided in this Agreement for the purposes of the guaranty herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby and (b) in the event of any such declaration of acceleration of such Obligations, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Parent for the purposes of this guaranty.

Section 13.8. No Subrogation. Notwithstanding any payment or payments made by the Parent hereunder, the Parent shall not be entitled to be subrogated to any of the rights of any holder of a Note against the Issuer or any collateral security or guaranty or right of offset held by any holder for the payment of the Obligations, nor shall the Parent seek or be entitled to seek any contribution or reimbursement from the Issuer or any Subsidiary Guarantor in respect of payments made by the Parent hereunder, until all amounts owing to the holders of the Notes by the Issuer on account of the Obligations are paid in full. If any amount shall be paid to the Parent on account of such subrogation rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held by the Parent in trust for the holders of the Notes, segregated from other funds of the Parent, and shall, forthwith upon receipt by the Parent, be turned over to the holders of the Notes in the exact form received by the Parent (duly indorsed by the Parent to the holders of the Notes, if required), to be applied against the Obligations.

Section 13.9. Marshalling. No holder of a Note shall be under any obligation: (a) to marshal any assets in favor of the Parent or in payment of any or all of the liabilities of the Issuer under or in respect of the Notes and this Agreement or the obligations of the Parent hereunder or (b) to pursue any other remedy that the Parent may or may not be able to pursue itself and that may lighten the Parent’s burden, any right to which the Parent hereby expressly waives.

Section 13.10. Transfer of Notes. All rights of any holder of a Note under this Section 13 shall be considered to be transferred or assigned at any time or from time to time upon the transfer of any Note held by such holder whether with or without the consent of or notice to the Parent under this Section 13.

Section 13.11. Consideration. The Parent has received, or shall receive, direct or indirect benefits from the making of this guaranty.

Prior to any sale or other disposition of any Note held by a Purchaser or its nominee, such Purchaser will, at its election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Note to the Issuer in exchange for a new Note or Notes pursuant to Section 14.2. The Issuer will afford the benefits of this Section 15.2 to any Institutional Investor that is the direct or indirect transferee of any Note purchased by a Purchaser under this Agreement and that has made the same agreement relating to such Note as the Purchasers have made in this Section 15.2.

Each Purchaser will maintain the confidentiality of such Confidential Information in accordance with procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered to such Purchaser, provided that such Purchaser may deliver or disclose Confidential Information to (1) its directors, officers, employees, agents, attorneys, trustees and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by its Notes), (2) its auditors, financial advisors and other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with this Section 21, (3) any other holder of any Note, (4) any Institutional Investor to which it sells or offers to sell such Note or any part thereof or any participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by this Section 21), (5) any Person from which it offers to purchase any Security of a Constituent Company (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by this Section 21), (6) any federal or state regulatory authority having jurisdiction over such Purchaser, (7) the NAIC or the SVO or, in each case, any similar organization, or any nationally recognized rating agency that requires access to information about such Purchaser’s investment portfolio, or (8) any other Person to which such delivery or disclosure may be necessary or appropriate (i) to effect compliance with any law, rule, regulation or order applicable to such Purchaser, (ii) in response to any subpoena or other legal process, (iii) in connection with any litigation to which such Purchaser is a party or (iv) if an Event of Default has occurred and is continuing, to the extent such Purchaser may reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under such Purchaser’s Notes, this Agreement or any Subsidiary Guaranty. Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 21 as though it were a party to this Agreement. On reasonable request by a Constituent Company in connection with the delivery to any holder of a Note of information required to be delivered to such holder under this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Constituent Companies embodying this Section 21.

In the event that as a condition to receiving access to information relating to a Constituent Company or its Subsidiaries in connection with the transactions contemplated by or otherwise pursuant to this Agreement, any Purchaser or holder of a Note is required to agree to a confidentiality undertaking (whether through Intralinks, another secure website, a secure virtual workspace or otherwise) which is different from this Section 21, this Section 21 shall not be amended thereby and, as between such Purchaser or such holder and the Constituent Companies, this Section 21 shall supersede any such other confidentiality undertaking.

Upon receipt of such notice, any reference to such Purchaser in this Agreement (other than in this Section 22), shall be deemed to refer to such Substitute Purchaser in lieu of such original Purchaser. In the event that such Substitute Purchaser is so substituted as a Purchaser hereunder and such Substitute Purchaser thereafter transfers to such original Purchaser all of the Notes then held by such Substitute Purchaser, upon receipt by the Constituent Companies of notice of such transfer, any reference to such Substitute Purchaser as a “Purchaser” in this Agreement (other than in this Section 22), shall no longer be deemed to refer to such Substitute Purchaser, but shall refer to such original Purchaser, and such original Purchaser shall again have all the rights of an original holder of the Notes under this Agreement.

Section 23. Miscellaneous.
