Ladies and Gentlemen:

Simon Property Group, L.P., a Delaware limited partnership (the "Operating Partnership"), confirms its agreement with each of the Initial Purchasers named in Schedule 1 hereto (collectively, the "Initial Purchasers," which term shall also include any initial purchaser substituted as hereinafter provided in Section 11 hereof), with respect to the issue and sale by the Operating Partnership and the purchase by the Initial Purchasers, acting severally and not jointly, of the respective principal amounts set forth in said Schedule 1 of $300,000,000 aggregate principal amount of its 4.875% senior unsecured notes due 2010 (the "2010 Notes") and $200,000,000 aggregate principal amount of its $5.450% senior unsecured notes due 2013 (the "2013 Notes" and, together with the 2010 Notes, the "Notes").

The Notes shall be issued under an indenture, dated as of November 26, 1996 (the "Original Indenture"), between the Operating Partnership and JPMorgan Chase Bank (formerly known as The Chase Manhattan Bank), as trustee (the "Trustee"). The title, aggregate principal amount, rank, interest rate or formula and timing of payments thereof, stated maturity date, redemption and/or repayment provisions, sinking fund requirements and any other variable terms of the Notes shall be established by or pursuant to an eleventh supplemental indenture to the Original Indenture (as so supplemented, and as the same may be amended or further supplemented from time to time, the "Indenture") to be entered into between the Operating Partnership and the Trustee on or prior to the Closing Time (as defined in Section 2(b)). Notes issued in book-entry form shall be issued to Cede & Co. as nominee of The Depository Trust Company ("DTC") pursuant to a letter agreement, to be dated as of the Closing Time (the "DTC Agreement"), among the Operating Partnership, the Trustee and DTC.

The Operating Partnership understands that the Initial Purchasers propose to make an offering of the Notes on the terms and in the manner set forth herein and agrees that the Initial Purchasers may resell, subject to the conditions set forth herein, all or a portion of the Notes to purchasers ("Subsequent Purchasers") at any time after the date of this Agreement. The Notes are to be offered and sold through the Initial Purchasers without being registered under the Securities Act of 1933, as amended (the "1933 Act"), in reliance upon exemptions therefrom. Pursuant to the terms of the Notes and the Indenture, investors that acquire Notes may only resell or otherwise transfer such Notes if such Notes are hereafter registered under the 1933 Act or if an exemption from the registration requirements of the 1933 Act is available (including the exemption afforded by Rule 144A ("Rule 144A") or Regulation S ("Regulation S") of the rules and regulations promulgated under the 1933 Act by the Securities and Exchange Commission (the "Commission")).

The Operating Partnership has prepared and delivered to each Initial Purchaser copies of an Offering Memorandum dated March 13, 2003 (the "Offering Memorandum") for use by such Initial Purchaser in connection with its solicitation of purchases of, or offering of, the Notes. "Offering Memorandum" means, with respect to any date or time referred to in this Agreement, the most recent

offering memorandum, as may be amended or supplemented, including exhibits thereto and any documents incorporated therein by reference, which has been prepared and delivered by the Operating Partnership to the Initial Purchasers in connection with their solicitation of purchases of, or offering of, the Notes. Capitalized terms used but not otherwise defined shall have the meanings given to those terms in the Offering Memorandum.

The Initial Purchasers and their direct and indirect transferees shall be entitled to the benefits of a Registration Rights Agreement, to be dated as of the Closing Time and to be substantially in the form attached hereto as Exhibit A (the "Registration Rights Agreement").

All references in this Agreement to financial statements and schedules and other information which is "contained," "included" or "stated" in the Offering Memorandum (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which are incorporated by reference in the Offering Memorandum, and all references in this Agreement to amendments or supplements to the Offering Memorandum shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the "1934 Act"), which is incorporated by reference in the Offering Memorandum.

The term "subsidiary" means a corporation, partnership or other entity, a majority of the outstanding voting stock, partnership interests or other equity interests, as the case may be, of which is owned or controlled, directly or indirectly, by the Operating Partnership and/or Simon Property Group, Inc., a Delaware corporation and the general partner of the Operating Partnership (the "Company") or by one or more other subsidiaries of the Operating Partnership and/or the Company.

SECTION 1. Representations and Warranties.

(a) Representations and Warranties by the Operating Partnership. The Operating Partnership represents and warrants to each Initial Purchaser, as of the date hereof and as of the Closing Time (as defined below) (in each case, a "Representation Date"), and agrees with each Initial Purchaser, as follows:

(1) Similar Offerings. None of the Company, the Operating Partnership, nor any of their affiliates, as such term is defined in Rule 501(b) under the 1933 Act (each, an "Affiliate"), has, directly or indirectly, solicited any offer to buy, sold or offered to sell or otherwise negotiated in respect of, or shall solicit any offer to buy or offer to sell or otherwise negotiate in respect of, in the United States or to any United States citizen or resident, any security which is or would be integrated with the sale of the Notes in a manner that would require the Notes to be registered under the ▇▇▇▇ ▇▇▇.

(2) Offering Memorandum. The Offering Memorandum does not, and at the Closing Time shall not, include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, that this representation, warranty and agreement shall not apply to statements in or omissions from the Offering Memorandum made in reliance upon and in conformity with information furnished to the Operating Partnership in writing by any Initial Purchaser expressly for use in the Offering Memorandum.

(3) Incorporated Documents. The Offering Memorandum shall incorporate by reference the most recent Annual Report of the Company and the Operating Partnership on Form 10-K filed with the Commission and each Quarterly Report of the Company and the Operating Partnership on Form 10-Q and each Current Report of the Company and the Operating Partnership on Form 8-K filed with the Commission since the filing of the end of the fiscal year to which such Annual Report relates. The documents incorporated or deemed to be incorporated by reference in the Offering Memorandum at the time they were or hereafter are filed with the Commission, complied and shall comply in all material respects with the requirements of the 1934 Act and the

rules and regulations of the Commission thereunder (the "1934 Act Regulations") and, when read together with the other information in the Offering Memorandum, at the time the Offering Memorandum was issued and at the Closing Time, did not and shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(4) Independent Accountants. The accountants who certified the financial statements and supporting schedules included, or incorporated by reference, in the Offering Memorandum were independent public accountants with respect to the Operating Partnership and its subsidiaries and the current accountants of the Operating Partnership are independent public accountants with respect to the Operating Partnership and its subsidiaries, in each case, as required by the rules and regulations of the Commission under the 1933 Act.

(5) Financial Statements. The financial statements included, or incorporated by reference, in the Offering Memorandum, together with the related schedules and notes, as well as those financial statements, schedules and notes of any other entity included therein, present fairly the financial position of the respective entity or entities or group presented therein at the respective dates indicated and the statement of operations, stockholders' equity and cash flows of such entity, as the case may be, for the periods specified. Such financial statements have been prepared in conformity with generally accepted accounting principles ("GAAP") applied on a consistent basis throughout the periods involved. The supporting schedules, if any, included, or incorporated by reference, in the Offering Memorandum present fairly, in accordance with GAAP, the information stated therein. The selected financial data, the summary financial information and other financial information and data included, or incorporated by reference, in the Offering Memorandum present fairly the information shown therein and have been compiled on a basis consistent with that of the audited financial statements included, or incorporated by reference, in the Offering Memorandum. In addition, any pro forma financial information and the related notes thereto, if any, included, or incorporated by reference, in the Offering Memorandum present fairly the information shown therein, have been prepared in accordance with the Commission's rules and guidelines and the guidelines of the American Institute of Certified Public Accountants ("AICPA") with respect to pro forma information and have been properly compiled on the bases described therein, and the assumptions used in the preparation thereof are reasonable and the adjustments used therein are appropriate to give effect to the transactions and circumstances referred to therein.

(6) Internal Accounting Controls. The Operating Partnership maintains a system of internal accounting controls sufficient to provide reasonable assurance that: (a) transactions are properly authorized; (b) assets are safeguarded against unauthorized or improper use; and (c) transactions are properly recorded and reported as necessary to permit preparation of its financial statements in conformity with United States GAAP.

(7) No Material Adverse Change in Business. Since the respective dates as of which information is given in the Offering Memorandum, except as otherwise stated therein, (a) there has been no material adverse change in the condition, financial or otherwise, or in the earnings, assets, business affairs or business prospects of the Company, the Operating Partnership, M.S. Management Associates, Inc., a Delaware corporation ("SPG Management Company"), M.S. Management Associates (Indiana), Inc., an Indiana corporation ("Management (Indiana)"), Simon MOA Management Company, Inc., an Indiana corporation ("MOA"), ▇▇▇▇▇▇▇▇▇ Properties Management, Inc., an Ohio corporation ("DRC Management Company," and together with SPG Management Company, Management (Indiana) and MOA, the "Management Companies"), and Simon Property Group (Delaware), Inc., ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ Property, Inc., SDG Forum Developers, Inc., ▇▇▇▇▇▇▇▇▇ Properties, Inc., ▇▇▇▇▇▇▇▇▇ Properties II, Inc., and ▇▇▇▇▇▇▇▇▇ Properties III, Inc. and any other subsidiary of the Company (collectively, the "REIT Subs") or

any subsidiary of the Operating Partnership (other than any Property Partnership (as defined below)) not listed among the foregoing entities, (the Company, the Operating Partnership, the Management Companies, the REIT Subs and such subsidiaries being sometimes hereinafter collectively referred to as the "Simon Entities" and individually as a "Simon Entity"), or of any entity which owns any Portfolio Property (as such term is defined in the Offering Memorandum) or any direct interest in any Portfolio Property (the "Property Partnerships") whether or not arising in the ordinary course of business, which, taken as a whole, would be material to the Operating Partnership (anything which, taken as a whole, would be material to the Operating Partnership, being hereinafter referred to as "Material;" and such a material adverse change, a "Material Adverse Effect"), (b) no casualty loss or condemnation or other adverse event with respect to the Portfolio Properties has occurred which would be Material, (c) there have been no transactions or acquisitions entered into by the Simon Entities or the Property Partnerships, other than those in the ordinary course of business, which would be Material, (d) except for distributions in amounts per unit that are consistent with past practices, there has been no distribution of any kind declared, paid or made by the Operating Partnership on any of its respective general, limited and/or preferred partnership interests, and (e) there has been no change in the capital stock of the corporate Simon Entities or in the partnership interests of the Operating Partnership or any Property Partnership, or any increase in the indebtedness of the Simon Entities, the Property Partnerships or the Portfolio Properties which would be Material.

(8) Good Standing of the Company. The Company has been duly organized and is validly existing as a corporation in good standing under the laws of the State of Delaware and has corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Offering Memorandum. The Company is duly qualified as a foreign corporation to transact business and is in good standing in each other jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure to so qualify or be in good standing would not result in a Material Adverse Effect.

(9) Good Standing of the Operating Partnership. The Operating Partnership is duly organized and validly existing as a limited partnership in good standing under the laws of the State of Delaware, with the requisite power and authority to own, lease and operate its properties, to conduct the business in which it is engaged and proposes to engage as described in the Offering Memorandum and to enter into and perform its obligations under this Agreement. The Operating Partnership is duly qualified or registered as a foreign partnership and is in good standing in each jurisdiction in which such qualification or registration is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure to so qualify or register would not have a Material Adverse Effect. The Company is the sole general partner of the Operating Partnership. The amended and restated agreement of limited partnership of the Operating Partnership (the "OP Partnership Agreement") is in full force and effect in the form in which it was filed as an exhibit to the Operating Partnership's Annual Report on Form 10-K for the year ended December 31, 2001, except for subsequent amendments relating to the admission of new partners to the Operating Partnership.

(10) Good Standing of Simon Entities. Each of the Simon Entities other than the Operating Partnership has been duly organized and is validly existing as a corporation, limited partnership, limited liability company or other entity, as the case may be, in good standing under the laws of the state of its jurisdiction of incorporation or organization, as the case may be, with the requisite power and authority to own, lease and operate its properties, and to conduct the business in which it is engaged or proposes to engage as described in the Offering Memorandum. Each such entity is duly qualified or registered as a foreign corporation, limited partnership or limited liability company or other entity, as the case may be, to transact business and is in good standing in each

jurisdiction in which such qualification or registration is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure to so qualify or register would not have a Material Adverse Effect. Except as otherwise stated in the Offering Memorandum, all of the issued and outstanding capital stock or other equity interests of each such entity have been duly authorized and validly issued and are fully paid and non-assessable, have been offered and sold in compliance with all applicable laws (including without limitation, federal or state securities laws) and are owned by the Company, the Management Companies or the Operating Partnership, in each case free and clear of any security interest, mortgage, pledge, lien, encumbrance, claim or equity (collectively, "Liens"). No shares of capital stock or other equity interests of such entities are reserved for any purpose, and there are no outstanding securities convertible into or exchangeable for any capital stock or other equity interests of such entities and no outstanding options, rights (preemptive or otherwise) or warrants to purchase or to subscribe for shares of such capital stock or any other securities of such entities, except as disclosed in the Offering Memorandum. No such shares of capital stock or other equity interests of such entities were issued in violation of preemptive or other similar rights arising by operation of law, under the charter or by-laws of such entity or under any agreement to which any Simon Entity is a party.

(11) Good Standing of Property Partnerships. Each of the Property Partnerships is duly organized and validly existing as a limited or general partnership, as the case may be, in good standing under the laws of its respective jurisdiction of formation. Each of the Property Partnerships has the requisite power and authority to own, lease and operate its properties, and to conduct the business in which it is engaged. Each of the partnership agreements of the Property Partnerships is in full force and effect. Each of the Property Partnerships is duly qualified or registered as a foreign partnership to transact business and is in good standing in each jurisdiction in which such qualification or registration is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure to so qualify or register would not have a Material Adverse Effect.

(12) Insolvency. Neither the Operating Partnership nor the Company (a) is "insolvent" as that term is defined in Section 101(32) of the United States Bankruptcy Code (the "Bankruptcy Code") (11 U.S.C.101(32)), Section 2 of the Uniform Fraudulent Transfer Act ("UFTA") or Section 2 of the Uniform Fraudulent Conveyance Act ("UFCA"), (b) has "unreasonably small capital" as that term is used in Section 548(a)(2)(ii) of the Bankruptcy Code or Section 5 of the UFCA, (C) is engaged or about to engage in a business or transaction for which its remaining property is "unreasonably small" in relation to the business or transaction as that term is used in Section 4 of the UFTA or (d) is unable to pay its debts as they mature or become due, within the meaning of Section 548(a)(2)(B)(iii) of the Bankruptcy Code, Section 4 of the UFTA and Section 6 of the UFCA. The Operating Partnership and the Company now own assets having a value both at "fair valuation" and at "present fair saleable value" greater than the amount required to pay its "debts" as such terms are used in Section 2 of the UFTA and Section 2 of the UFCA. Neither the Operating Partnership nor the Company will be rendered insolvent by the execution and delivery of this Agreement or by the transactions contemplated hereunder.

(13) Capitalization. The issued and outstanding units of general, limited and/or preferred partner interests of the Operating Partnership are as set forth in the Company's Current Report on Form 8-K filed on February 7, 2003 (except for subsequent issuances thereof, if any, contemplated under this Agreement or referred to in the Offering Memorandum). Such units of partners' equity have been duly authorized and validly issued by the Operating Partnership and are fully paid and non-assessable and have been offered and sold or exchanged in compliance with all applicable laws (including, without limitation, federal and state securities laws), and none of such units of partners' equity were issued in violation of preemptive or other similar rights arising by operation of law, under the certificate of limited partnership and the OP Partnership Agreement of the Operating

Partnership or under any agreement to which the Operating Partnership or any of the other Simon Entities is a party or otherwise. There are no units of partners' equity of the Operating Partnership reserved for any purpose and there are no outstanding securities convertible into or exchangeable for any units of partners' equity of the Operating Partnership and, other than this Agreement, there are no outstanding options, rights (preemptive or otherwise) or warrants to purchase from the Operating Partnership or to subscribe for with the Operating Partnership such units of partners' equity or any other securities of the Operating Partnership.

(14) Authorization of Purchase Agreement. This Agreement has been duly authorized, executed and delivered by the Operating Partnership and, assuming due authorization, execution and delivery by or on behalf of the Initial Purchasers, shall constitute a valid and legally binding agreement of the Operating Partnership, enforceable against the Operating Partnership in accordance with its terms except to the extent that enforceability thereof may be limited by (a) bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or other similar laws now or hereafter in effect relating to creditors' rights generally and (b) general principles of equity (regardless of whether considered at law or in equity).

(15) Authorization of the Registration Rights Agreement. The Registration Rights Agreement has been duly authorized, executed and delivered by the Operating Partnership and, assuming the due authorization, execution and delivery thereof by or on behalf of the Initial Purchasers, shall constitute a valid and legally binding agreement of the Operating Partnership, enforceable against the Operating Partnership in accordance with its terms except (a) to the extent that enforceability thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or other similar laws now or hereafter in effect relating to creditors' rights generally and (ii) general principles of equity (regardless of whether considered at law or in equity); (b) that rights to indemnity and contribution contained in the Registration Rights Agreement may be limited by state or federal securities laws or pubic policy and (c) that rights to receive the Special Interest Premium (as such term is defined therein) contained therein, to the extent it may be construed as liquidated damages, may be unenforceable, in whole or in part.

(16) Authorization of the Indenture. For the Notes being sold pursuant to this Agreement, the Indenture has been, or prior to the issuance of the Notes thereunder shall have been, duly authorized, executed and delivered by the Operating Partnership and, upon such authorization, execution and delivery, shall constitute a valid and legally binding agreement of the Operating Partnership, enforceable against the Operating Partnership, in accordance with its terms, except as the enforcement thereof may be limited by (a) bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting creditors' rights generally, (b) general equitable principles (regardless of whether enforcement is considered in a proceeding in equity or at law), (c) requirements that a claim with respect to any Notes issued under the Indenture that are payable in a foreign or composite currency (or a foreign or composite currency judgment in respect of such claim) be converted into U.S. dollars at a rate of exchange prevailing on a date determined pursuant to applicable law, or (d) governmental authority to limit, delay or prohibit the making of payments outside the United States. The Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended, (the "1939 Act") and conforms, in all material respects, to the descriptions thereof contained in the Offering Memorandum.

(17) Authorization of Notes. The Notes being sold pursuant to this Agreement have been, duly authorized by the Operating Partnership for issuance and sale pursuant to this Agreement. Such Notes, when issued and authenticated in the manner provided for in the applicable Indenture and delivered by the Operating Partnership pursuant to this Agreement against payment of the consideration therefor specified in this Agreement, shall constitute valid and legally binding, unsecured obligations of the Operating Partnership, enforceable against the Operating Partnership, in accordance with their terms, except as the enforcement thereof may be limited by bankruptcy,

insolvency, reorganization, moratorium or other similar laws relating to or affecting creditors' rights generally or by general equitable principles, and except further as enforcement thereof may be limited by (a) requirements that a claim with respect to any Notes denominated other than in U.S. dollars (or a foreign or composite currency judgment in respect of such claim) be converted into U.S. dollars at a rate of exchange prevailing on a date determined pursuant to applicable law or (b) governmental authority to limit, delay or prohibit the making of payments outside the United States. Such Notes shall be in the form contemplated by, and each registered holder thereof shall be entitled to the benefits of, the applicable Indenture. Such Notes rank and shall rank equally with all unsecured indebtedness (other than subordinated indebtedness) of the Operating Partnership that is outstanding on a Representation Date or that may be incurred thereafter and senior to all subordinated indebtedness that is outstanding on a Representation Date or that may be incurred thereafter, except that such Notes shall be effectively subordinate to the prior claims of each secured mortgage lender to any specific Portfolio Property which secures such lender's mortgage and any claims of creditors of entities wholly or partly owned, directly or indirectly, by the Operating Partnership.

(18) Descriptions of the Notes and the Indenture. The Notes being sold pursuant to this Agreement and the Indenture shall conform in all material respects to the statements relating thereto contained in the Offering Memorandum and shall be in substantially the respective forms previously delivered to the Initial Purchasers.

(19) Absence of Defaults and Conflicts. None of the Simon Entities or any Property Partnership is in violation of its charter, by-laws, certificate of limited partnership or partnership agreement or other organizational document, as the case may be, or in default in the performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument to which each entity is a party or by which or any of them may be bound, or to which any of its property or assets or any Portfolio Property may be bound or subject (collectively, "Agreements and Instruments"), except for such violations (other than with respect to the charter, by-laws, partnership agreement, or other organizational document of such entities) or defaults that would not result in a Material Adverse Effect. The execution, delivery and performance of this Agreement, the Notes, the Indenture, the Registration Rights Agreement and any other agreement or instrument entered into or issued or to be entered into or issued by the Operating Partnership in connection with the transactions contemplated hereby or thereby or in the Offering Memorandum and the consummation of the transactions contemplated herein and in the Offering Memorandum (including the issuance and sale of the Notes and the use of the proceeds from the sale of the Notes as described under the caption "Use of Proceeds") and compliance by the Operating Partnership with its obligations hereunder and thereunder have been duly authorized by all necessary partnership action, and do not and shall not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any assets, properties or operations of the Operating Partnership or any other Simon Entity or any Property Partnership pursuant to, any Agreements and Instruments, except for such conflicts, breaches, defaults, Repayment Events or liens, charges or encumbrances that, singly or in the aggregate, would not result in a Material Adverse Effect, nor shall such action result in any violation of the provisions of the partnership agreement and certificate of limited partnership of the Operating Partnership or the organizational documents of any other Simon Entity or any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Operating Partnership, any other Simon Entity or any Property Partnership or any of their assets, properties or operations, except for such violations that would not have a Material Adverse Effect. As used herein, a "Repayment Event" means any event or condition which gives the holder of any note,

debenture or other evidence of indebtedness (or any person acting on such holder's behalf) the right to require the repurchase, redemption or repayment of all or a material portion of such indebtedness by the Operating Partnership, any other Simon Entity or any Property Partnership.

(20) Absence of Labor Dispute. Except as otherwise described in the Offering Memorandum, no labor dispute with the employees of the Operating Partnership or any other Simon Entity or any Property Partnership exists or, to the knowledge of the Operating Partnership, is imminent, and the Operating Partnership is not aware of any existing or imminent labor disturbance by the employees of any of its or any subsidiary's principal suppliers, manufacturers, customers or contractors, which dispute or disturbance, in either case, may reasonably be expected to result in a Material Adverse Effect.

(21) ERISA Compliance.

No sale of the Notes to any one Subsequent Purchaser shall be for less than U.S. $1,000 ($100,000 for Institutional Accredited Investors) principal amount and no Note shall be issued in a smaller principal amount. If the Subsequent Purchaser is a non-bank fiduciary acting on behalf of others, each person for whom it is acting must purchase at least U.S. $100,000 principal amount of the Notes.

(vi) Restrictions on Transfer. The transfer restrictions and the other provisions set forth in the Offering Memorandum under the heading "Notice to Investors," including the legend required thereby, shall apply to the Notes except as otherwise agreed by the Operating Partnership and the Initial Purchasers.

(vii) Delivery of Offering Memorandum. Each Initial Purchaser shall deliver to each Subsequent Purchaser of the Notes, in connection with its original distribution of the Notes, a copy of the Offering Memorandum, as amended and supplemented at the date of such delivery, if required by applicable law.

(b) Covenants of the Operating Partnership. The Operating Partnership covenants with each Initial Purchaser as follows:

(i) Integration. The Operating Partnership agrees that it shall not and shall cause its Affiliates not to solicit, directly or indirectly, any offer to buy or make any offer or sale of, or otherwise negotiate in respect of, securities of the Operating Partnership of any class if, as a result of the doctrine of "integration" referred to in Rule 502 under the 1933 Act, such offer or sale would render invalid (for the purpose of (i) the sale of the Notes by the Operating Partnership to the Initial Purchasers, (ii) the resale of the Notes by the Initial Purchasers to Subsequent Purchasers or (iii) the resale of the Notes by such Subsequent Purchasers to others) the exemption

from the registration requirements of the 1933 Act provided by Section 4(2) thereof or by Rule 144A or by Regulation S thereunder or otherwise.

(ii) Rule 144A Information. The Operating Partnership agrees that, in order to render the Notes eligible for resale pursuant to Rule 144A under the 1933 Act, while any of the Notes remain outstanding, it shall make available, upon request, to any holder of Notes or prospective purchasers of Notes the information specified in Rule 144A(d)(4), unless the Operating Partnership furnishes information to the Commission pursuant to Section 13 or 15(d) of the 1934 Act (such information, whether made available to holders or prospective purchasers or furnished to the Commission, is herein referred to as "Additional Information").

(iii) Restriction on Repurchases. Until the expiration of two years after the original issuance of the Notes, the Operating Partnership shall not, and shall cause its Affiliates not to, purchase or agree to purchase or otherwise acquire any Notes which are "restricted securities" (as such term is defined under Rule 144(a)(3) under the 1933 Act), whether as beneficial owner or otherwise (except as agent acting as a securities broker on behalf of and for the account of customers in the ordinary course of business in unsolicited broker's transactions), unless such repurchased Notes are promptly retired.

(c) Resale Pursuant to Rule 903 of Regulation S or Rule 144A. Each Initial Purchaser understands that the Notes have not been and shall not be registered under the 1933 Act and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons except in accordance with Regulation S under the 1933 Act or pursuant to an exemption from the registration requirements of the 1933 Act. Each Initial Purchaser severally represents and agrees, that, except as permitted by Section 6(a) above, it has offered and sold Notes and shall offer and sell Notes (i) as part of their distribution at any time and (ii) otherwise until forty days after the later of the date upon which the offering of the Notes commences and the Closing Time, only in accordance with Rule 903 of Regulation S, or another applicable exemption from the registration provisions of the 1933 Act or Rule 144A under the 1993 Act. Accordingly, none of the Initial Purchasers, their affiliates or any persons acting on their behalf have engaged or shall engage in any directed selling efforts with respect to Notes, and the Initial Purchasers, their affiliates and any person acting on their behalf have complied and shall comply with the offering restriction requirements of Regulation S. Each Initial Purchaser agrees that, at or prior to confirmation of a sale of Notes (other than a sale of Notes pursuant to Rule 144A) it shall have sent to each distributor, dealer or person receiving a selling concession, fee or other remuneration that purchases Notes from it or through it during the restricted period a confirmation or notice to substantially the following effect:

"The Notes covered hereby have not been registered under the 1933 Act and may not be offered or sold within the United States or to or for the Account or benefit of U.S. persons (i) as part of their distribution at any time and (ii) otherwise until forty days after the later of the date upon which the offering of the Notes commenced and the date of closing, except in either case in accordance with Regulation S, Rule 144A under the 1933 Act or another exemption from the registration requirements of the 1933 Act. Terms used above have the meaning given to them by Regulation S."

Terms used in the above paragraph have the meanings given to them by Regulation S.

(d) Representations and Warranties of Initial Purchasers. Each Initial Purchaser severally represents and agrees that it has not entered and shall not enter into any contractual arrangements with respect to the distribution of the Notes, except with its affiliates or with the prior written consent of the Operating Partnership.

SECTION 7. Indemnification.

(a) Indemnification of Initial Purchasers. The Operating Partnership agrees to indemnify and hold harmless each Initial Purchaser and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and their respective officers, directors and employees as follows:

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

(2) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided, that (subject to Section 7(d) below) any such settlement is effected with the written consent of the Operating Partnership; and

(3) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Initial Purchasers), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (1) or (2) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Operating Partnership by any Initial Purchaser expressly for use in the Offering Memorandum (or any amendment or supplement thereto).

(b) Indemnification of Operating Partnership, Company and Company's Directors and Officers. Each Initial Purchaser severally, and not jointly, agrees to indemnify and hold harmless the Operating Partnership, the Company, each of the Company's directors, and each person, if any, who controls the Operating Partnership or the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Offering Memorandum (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Operating Partnership by such Initial Purchaser expressly for use in the Offering Memorandum (or any amendment or supplement thereto).

(c) Actions Against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 7(a) above, counsel to the indemnified parties shall be selected by the Initial Purchasers, and, in the case of parties indemnified pursuant to Section 7(b) above, counsel to the indemnified parties shall be selected by the Operating Partnership. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party

shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 7 or Section 8 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement Without Consent If Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel in accordance with the provisions hereof, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(a)(2) effected without its written consent if (i) such settlement is entered into in good faith by the indemnified party more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 8. Contribution.

If the indemnification provided for in Section 7 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Operating Partnership, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Notes pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Operating Partnership, on the one hand, and of the Initial Purchasers, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Operating Partnership, on the one hand, and the Initial Purchasers, on the other hand, in connection with the offering of the Notes pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of such Notes (before deducting expenses) received by the Operating Partnership and the total discount received by the Initial Purchasers, bear to the aggregate initial offering price of the Notes.

The relative fault of the Operating Partnership, on the one hand, and the Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Operating Partnership or by the Initial Purchasers and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Operating Partnership and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Initial

Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 8 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 8, no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Notes purchased by it and sold to a Subsequent Purchaser were sold to such Subsequent Purchaser exceeds the amount of any damages which such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

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

For purposes of this Section 8, each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Initial Purchaser, and each director of the Company, and each person, if any, who controls the Operating Partnership or the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Operating Partnership. The Initial Purchasers' respective obligations to contribute pursuant to this Section 8 are several in proportion to the number, or aggregate principal amount, as the case may be, of Notes set forth opposite their respective names in Schedule 1 hereto and not joint.

SECTION 9. Representations, Warranties and Agreements to Survive Delivery.

All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Operating Partnership or the Company or authorized representatives of each of the Operating Partnership or the Company submitted pursuant hereto or thereto shall remain operative and in full force and effect, regardless or any investigation made by or on behalf of any Initial Purchaser or any controlling person, or by or on behalf of the Operating Partnership or the Company, and shall survive delivery of and payment for the Notes.

SECTION 10. Termination.

(a) Termination; General. The Initial Purchasers may terminate this Agreement, by notice to the Operating Partnership, at any time at or prior to the Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Offering Memorandum, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Operating Partnership and the other Simon Entities considered as one enterprise, whether or not arising in the ordinary course of business, the effect of which is such as to make it, in the reasonable judgment of the Initial Purchasers, impracticable or inadvisable to market the Notes or to enforce contracts for the sale of the Notes, or (ii) if there has occurred (A) any material adverse change in the financial markets in the United States or internationally, (B) any outbreak of hostilities or escalation thereof or other calamity or crisis, (C) a declaration by the United States of a national emergency or war, or (D) any change or development involving a prospective change in national or international political, financial, or economic conditions, in each case, the effect of which is such as to make it, in the judgment of the Initial Purchasers, impracticable or inadvisable to market the Notes or to enforce contracts for the sale of the Notes, or (iii) if trading in any securities of the Company has been suspended or materially limited by the

Commission or the New York Stock Exchange, or if trading generally on the New York Stock Exchange, the Nasdaq National Market or the American Stock Exchange or in the over-the-counter market has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority, or (iv) if a banking moratorium has been declared by either Federal, New York, or Delaware authorities, or (v) a material disruption in commercial banking or securities settlement or clearance services in the United States has occurred, or (vi) if the rating assigned by any nationally recognized statistical rating organization to any debt securities of the Operating Partnership as of the date hereof shall have been downgraded since such date or if any such rating organization shall have publicly announced that it has placed any series of debt securities of the Operating Partnership under surveillance or review, with possible negative implications, as to the rating of such debt securities or any of the Operating Partnership's other securities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section 10, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided, further, that Sections 7, 8 and 9 hereof shall survive such termination and remain in full force and effect.

SECTION 11. Default by One of the Initial Purchasers. If one of the Initial Purchasers shall fail at the Closing Time to purchase the Notes which it is obligated to purchase under this Agreement (the "Defaulted Notes"), the other Initial Purchaser shall have the right, within 24 hours thereafter, to make arrangements for any other Initial Purchasers to purchase all, but not less than all, of the Defaulted Notes in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the non-defaulting Initial Purchaser shall not have completed such arrangements within such 24-hour period, then:

(a) if the number of Defaulted Notes does not exceed 10% of the aggregate principal amount of the Notes to be purchased hereunder, the non-defaulting Initial Purchaser shall be obligated to purchase the full amount thereof, or

(b) if the number of Defaulted Notes exceeds 10% of the aggregate principal amount of the Notes to be purchased hereunder, this Agreement shall terminate without liability on the part of the non-defaulting Initial Purchaser.

No action taken pursuant to this Section shall relieve any defaulting Initial Purchaser from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, either the Initial Purchasers or the Operating Partnership shall have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the Offering Memorandum or in any other documents or arrangements. As used herein, the term "Initial Purchaser" includes any person substituted for an Initial Purchaser under this Section 11.

SECTION 12. Notices.

All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Initial Purchasers shall be directed to UBS Warburg LLC at ▇▇▇ ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, attention of ▇▇▇▇▇ ▇▇▇▇▇, Managing Director; and notices to the Simon Entities shall be directed to any of them at National City Center, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇, attention of Mr. ▇▇▇▇▇ ▇▇▇▇▇, with a copy to ▇▇▇▇▇ & ▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇, attention of ▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, Esq.

SECTION 13. Parties.

This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Initial Purchasers, the Operating Partnership, the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 7 and 8 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the parties hereto and thereto and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives and the Company, and for the benefit of no other person, firm or corporation.

Exhibit A

FORM OF REGISTRATION RIGHTS AGREEMENT

(Please see attached copy of the Registration Rights Agreement.)

Exhibit B-1

FORM OF OPINION OF SPECIAL COUNSEL
FOR THE COMPANY AND THE OPERATING PARTNERSHIP
TO BE DELIVERED PURSUANT TO SECTION 5(b)

(1) The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware.

(2) The Company has the corporate power and authority to own, lease and operate its properties, to conduct the business in which it is engaged or proposes to engage as described below, and to enter into and perform its obligations under, or as contemplated under, this Agreement.

(4) This Agreement has been duly and validly authorized by the Operating Partnership and the Company. Any one of the Co-Chairmen of the Board, Chief Executive Officer, President, any Vice President, the Treasurer, any Assistant Treasurer, the Secretary, or any Assistant Secretary of the Company (hereinafter, collectively, the "Authorized Officers") has been duly authorized to execute and deliver this Agreement for the Company and as the general partner of the Operating Partnership, and, assuming each has been executed and delivered by any one of the Authorized Officers, this Agreement is duly and validly executed and delivered by the Operating Partnership and the Company.

(5) The execution, delivery and performance of this Agreement, the Indenture and the Registration Rights Agreement, the consummation of the transactions contemplated in this Agreement, and compliance by the Operating Partnership with its obligations under this Agreement, the Indenture and the Registration Rights Agreement does not and will not, whether with or without the giving of notice or the passage of time or both, conflict with or constitute a breach of, or default under (i) any provisions of the certificate or agreement of limited partnership of the Operating Partnership; (ii) any applicable law, statute, rule, regulation of Delaware; or (iii) to such counsel's knowledge, any Delaware order or Delaware administrative or court decree, binding upon the Operating Partnership or to which the Operating Partnership is subject, except, in the case of (ii) and (iii) above, for conflicts, breaches, violations or defaults that in the aggregate would not have a Material Adverse Effect.

(6) The documents filed pursuant to the 1934 Act and incorporated by reference in the Offering Memorandum (other than the financial statements and supporting schedules therein and other financial data, as to which no opinion need be rendered), when they were filed with the Commission, complied as to form in all material respects with the requirements of the 1933 Act or the 1934 Act, as applicable, and the rules and regulations of the Commission thereunder. In passing upon compliance as to the form of such documents, such counsel may have assumed that the statements made or incorporated by reference therein are complete and correct.

(7) The information in the Offering Memorandum under "Description of Notes," "Certain Federal Income Tax Consequences," and "State and Local Tax Considerations" and the description of the Notes included therein, to the extent that it purports to summarize matters of law, descriptions of statutes, rules or regulations, summaries of legal matters, the Operating Partnership's organizational documents or legal proceedings, or legal conclusions, has been reviewed by such counsel, is correct and presents fairly the information required to be disclosed therein in all material respects.

(8) None of the Operating Partnership, any of the Simon Entities or any Property Partnership is required to be registered as an investment company under the 1940 Act.

B-1-1

(9) The Notes being sold pursuant to this Agreement have been duly authorized on behalf of the Operating Partnership by the Company as the general partner of the Operating Partnership for issuance and sale to the Initial Purchasers pursuant to this Agreement and the Indenture and, when executed and issued and authenticated in the manner provided for in the Indenture and delivered by the Operating Partnership pursuant to this Agreement against payment of the consideration therefor, (i) the Notes will constitute valid and legally binding obligations of the Operating Partnership enforceable against the Operating Partnership in accordance with their terms, except as the enforcement thereof may be limited (A) by bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer, moratorium or other similar laws relating to or affecting creditors' rights generally, (B) by general equitable principles (regardless of whether such enforceability is considered in a proceeding in equity or law), or (C) by federal courts with respect to the enforceability in such courts of forum selection clauses, and (ii) each holder of the Notes will be entitled to the benefits of the Indenture. The Notes are in the form contemplated by the Indenture.

(10) The Company has, at all times since the effective date of its election to be taxed as a "real estate investment trust" under the Code, been organized in conformity with the requirements for qualification and taxation as a "real estate investment trust" under the Code and its proposed organization structure will permit it to remain so qualified.

(11) The Indenture has been duly qualified under the 1939 Act and has been duly and validly authorized, executed and delivered by the Operating Partnership and (assuming due authorization, execution and delivery thereof by the Trustee) constitutes a valid and legally binding agreement of the Operating Partnership, enforceable against the Operating Partnership in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting creditors' rights generally or by general equitable principles and except further as enforcement thereof may be limited by (i) requirements that a claim with respect to any Notes denominated other than in U.S. Dollars (or a foreign currency or composite currency judgment in respect of such claim) be converted into U.S. dollars at a rate of exchange prevailing on a date determined pursuant to applicable law, (ii) governmental authority to limit, delay or prohibit the making of payments outside the United States, or (iii) federal courts with respect to the enforceability in such courts of forum selection clauses.

(12) Assuming the correctness of the representations and warranties and the compliance by the Operating Partnership and the Initial Purchasers with their respective covenants set forth in the Purchase Agreement, the offer and sale of the Notes to the Initial Purchasers and to each Subsequent Purchaser solely in the manner and under the circumstances contemplated by this Agreement and the Offering Memorandum are exempt from the registration requirements of the 1933 Act.

(13) The Registration Rights Agreement has been duly and validly authorized, executed and delivered by the parties thereto and is a valid and binding agreement, enforceable against the parties thereto in accordance with its terms, except as such enforceability may be subject to (i) bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or transfer or similar laws affecting creditors' rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (iii) limitations under state or federal securities laws or public policy with respect to the rights to indemnity and contribution contained in the Registration Rights Agreement.

In connection with the preparation of the Offering Memorandum, such counsel has participated in conferences with officers and other representatives of the Operating Partnership and the independent public accountants for the Operating Partnership and the Company at which the contents of the Offering Memorandum and related matters were discussed. On the basis of such participation and review, but without independent verification by such counsel of, and without assuming any responsibility for, the accuracy, completeness or fairness of the statements contained in the Offering

B-1-2

Memorandum or any amendments or supplements thereto, no facts have come to the attention of such counsel that would lead such counsel to believe that the Offering Memorandum or any amendment or supplement thereto (except for financial statements, the schedules and other financial data included therein, as to which such counsel need make no statement), at the time the Offering Memorandum was issued, at the time any such amended or supplemented Offering Memorandum was issued or at the Closing Time, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

In rendering such opinion, such counsel may rely as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on certificates of responsible officers of the Operating Partnership and public officials. Such opinion shall not state that it is to be governed or qualified by, or that it is otherwise subject to, any treatise, written policy or other document relating to legal opinions, including, without limitation, the Legal Opinion Accord of the ABA Section of Business Law (1991).
