WHO WE ARE

        We own, operate, manage, lease, acquire, expand and develop real estate properties, primarily regional malls and community shopping centers. We have elected to be taxed as a real estate investment trust or REIT for federal income tax purposes.

        The core of our business originated with the shopping center businesses of Melvin Simon, Herbert Simon, David Simon and other members and associates of the Simon family. We have grown significantly by acquiring properties and merging with other real estate companies, including our merger with DeBartolo Realty Corporation in 1996 and our combination with Corporate Property Investors, Inc. in 1998.

        As of June 30, 2004, we and our majority-owned subsidiary, Simon Property Group, L.P. or the Operating Partnership, owned or held an interest in 247 income-producing properties in North America which consisted of 176 regional malls, 67 community shopping centers, and four office and mixed-use properties in 37 states, Canada and Puerto Rico. Mixed-use properties are properties whose operating income includes two or more significant retail, office, and/or hotel components. As of the same date, we owned interests in four parcels of land held for future development and had ownership interests in other real estate assets in the United States. Finally, we had ownership interests in 48 assets in Europe (France, Italy, Poland and Portugal).

        Our predecessor was organized as a Massachusetts business trust in 1971 and reorganized as a Delaware corporation on March 10, 1998. Our principal executive offices are located at National City Center, Suite 15 East, 115 West Washington Street, Indianapolis, Indiana 46204; our telephone number is (317) 636-1600. Our Internet website address is www.simon.com. The information in our website is not incorporated by reference into this prospectus.

        If you want to find more information about us, please see the sections entitled "Where You Can Find More Information" and "Incorporation of Information We File with the SEC" in this prospectus.


RECENT DEVELOPMENTS

        On October 14, 2004, we acquired all of the outstanding common stock of Chelsea Property Group, Inc. ("Chelsea") and its operating partnership subsidiary in a transaction valued at approximately $3.5 billion. In connection with the transaction, Chelsea's operating partnership became our wholly-owned subsidiary. We issued 12,978,795 shares of common stock, 13,261,712 shares of a new issue of convertible preferred stock and paid $1.591 million in cash. We financed the cash portion of the purchase price with a twenty-four month, $1.8 billion bridge loan that bears interest at LIBOR plus 55 basis points. LIBOR at June 30, 2004 was 1.35%. Chelsea unit holders received 4,652,232 common units of limited partnership interest and 4,753,794 units of a new issue of convertible preferred units. In addition, we also assumed Chelsea's existing indebtedness and preferred stock, which totaled approximately $1.3 billion as of June 30, 2004. The Chelsea portfolio is comprised of 60 premium outlet and other shopping centers containing 16.9 million square feet of gross leasable area in 31 states and Japan.


USE OF PROCEEDS

        We will not receive any proceeds from the sale of the shares by the selling stockholders.

        The selling stockholders will pay any underwriting discounts and commissions and expenses they incur for brokerage, accounting, tax or legal services or any other expenses they incur in disposing of the shares. We will bear all other costs, fees and expenses incurred in effecting the registration of the shares covered by this prospectus. These may include, without limitation, all registration and filing fees, NYSE listing fees, fees and expenses of our counsel and accountants, and blue sky fees and expenses.

RISK FACTORS

        You should carefully consider the following risks, along with the other information contained or incorporated by reference in this prospectus before you decide to purchase any of our securities. If any of the following events actually occurs, our business, financial condition and results of operations would likely suffer, possibly materially.

Risk Factors Relating to the Series D 8% Preferred Stock

        There is no established trading market for the Series D 8% Preferred Stock and there can be no assurance as to the development or liquidity of any market for such securities, the ability of the holders to sell their Series D 8% Preferred Stock or the price at which holders of the Series D 8% Preferred Stock may be able to sell such securities. Future trading prices of the Series D 8% Preferred Stock will depend on many factors, including, among other things, prevailing interest rates, our operating results and the market for similar securities. In addition, we do not intend to list the Series D 8% Preferred Stock on any national securities exchange or to seek the admission thereof for trading on any automated dealer quotation system.

        The Series D 8% Preferred Stock will rank junior to all of our liabilities. In the event of our bankruptcy, liquidation or winding-up, our assets will be available to pay obligations on the Series D 8% Preferred Stock, only after all of our indebtedness and other liabilities have been paid. In addition, the Series D 8% Preferred Stock will effectively rank junior to all existing and future liabilities of our subsidiaries and any capital stock of our subsidiaries held by others. The rights of holders of the Series D 8% Preferred Stock to participate in the distribution of assets of our subsidiaries will rank junior to the prior claims of each subsidiary's creditors and any such other equity holders. As of June 30, 2004, we had total unaudited consolidated liabilities of approximately $12.0 billion. Consequently, if we are forced to liquidate our assets to pay creditors, we may not have sufficient assets remaining to pay amounts due on any or all of our preferred stock then outstanding. We and our subsidiaries may incur substantial amounts of additional debt and other obligations that will rank senior to the Series D 8% Preferred Stock, and the terms of the Series D 8% Preferred Stock will not limit the amount of such debt or other obligations that we may incur, except that we will not be able to issue preferred stock senior to the Series D 8% Preferred Stock without the approval of holders of at least a majority in liquidation preference of the shares of Series D 8% Preferred Stock and 8.00% Cumulative Convertible Preferred Units of the Operating Partnership then outstanding.

        Our charter authorizes us to issue up to 100,000,000 shares of preferred stock in one or more series on terms determined by our board of directors. As of October 15, 2004, we had 13,261,712 shares of preferred stock outstanding. Our future issuance of any series of preferred stock under our charter could therefore effectively diminish our ability to pay dividends on, and the liquidation preference of, the Series D 8% Preferred Stock.

Risk Factors Relating to Simon Property Generally

        As of June 30, 2004, unaudited consolidated mortgages and other indebtedness for which we are liable totaled $11.1 billion, of which approximately $482.8 million matures during the second half of 2004, including recurring principal amortization. We are subject to the risks normally associated with debt financing, including the risk that our cash flow from operations will be insufficient to meet required debt service. Our debt service costs generally will not be reduced when developments, such as the entry of new competitors or the loss of major tenants, could cause a reduction in income from a property. Should such events occur, our operations and ability to make expected distributions to stockholders may be adversely affected. If a property is mortgaged to secure payment of indebtedness and we are unable to pay that indebtedness, the property could be transferred to the mortgagee resulting in a loss of income and a decline in asset value.

        As of June 30, 2004, approximately $2.1 billion of our total unaudited consolidated debt adjusted to reflect outstanding derivative instruments was subject to floating interest rates. In a rising interest rate environment, these debt service costs will increase. In addition, we may not be able to refinance maturing fixed-rate debt on as favorable terms, or at all. Increased debt service costs would adversely affect our cash flow and the amounts of cash we have available for distribution to our stockholders.

        We use interest rate hedging arrangements to manage our exposure to interest rate volatility, but these arrangements may expose us to additional risks. Although our interest rate risk management policy establishes minimum credit ratings for counterparties, this does not eliminate the risk that a counterparty may fail to honor its obligations. Developing an effective interest rate risk strategy is complex and no strategy can completely insulate us from risks associated with interest rate fluctuations. There can be no assurance that our hedging activities will have the desired beneficial impact on our results of operations or financial condition. These hedging agreements may involve costs, such as transaction fees or breakage costs, if we terminate them.

        One of the factors that may influence the price of our securities in public markets is the annual distribution rate we pay as compared with the yields on alternative investments. Any significant increase in interest rates could lead holders of our securities to seek higher yields through other investments, which could adversely affect the market price of our securities.

        We face a wide range of competition that could affect our ability to operate profitably.

        Shopping malls compete with other retail properties for tenants on the basis of the rent charged and location. The principal competition for existing shopping malls may come from future shopping malls that will be located in the same market areas and from mail order and electronic commerce. There is also considerable competition to acquire desirable real estate. The competition is provided by real estate investment trusts, insurance companies, private pension plans and private developers. Additionally, our credit rating and leverage will affect our competitive position in the public debt and equity markets.

        We face competition from other shopping mall developers for the acquisition of prime development sites and for tenants and are subject to the risks of real estate development, including the lack of financing, construction delays, environmental requirements, budget overruns and lease-up. We compete with other real estate operations in seeking management, leasing revenues, land for

3


development and properties for acquisition. In addition, retailers at our properties face increasing competition from discount shopping centers, outlet malls, catalogues, discount shopping clubs and electronic commerce. With respect to many of our properties, there are similar properties within the same market area. The existence of competitive properties affects our ability to lease space and the level of rents we can obtain. Renovations and expansions at competing malls could negatively affect our properties. Increased competition could adversely affect our revenues.

        Our concentration in the retail shopping center real estate market means that we are subject to factors that affect the retail environment generally, including the level of consumer spending, the willingness of retailers to lease space in our shopping centers and tenant bankruptcies. These factors include changes in economic conditions, consumer confidence and terrorist activities.

        We are subject to the risks that, upon expiration of leases for space in our properties, the premises may not be relet or the terms of reletting, including the cost of concessions to tenants, may be less favorable than current lease terms. If we are unable to relet all or a substantial portion of this space or if the rental rates upon such reletting are significantly lower than expected rates, our cash generated before debt repayments and capital expenditures and ability to make expected distributions to stockholders would be adversely affected.

        Regional malls are typically anchored by well-known department stores and other tenants who generate shopping traffic at the mall. The value of our properties would be adversely affected if tenants or anchors failed to meet their contractual obligations, sought concessions in order to continue operations or ceased their operations. If the sales of stores operating in our properties were to decline significantly due to economic conditions, closing of anchors or for other reasons, tenants may be unable to pay their minimum rents or expense recovery charges. In the event of default by a tenant or anchor, we may experience delays and costs in enforcing our rights as landlord.

        We have limited control with respect to certain properties partially owned or managed by third parties.

        As of June 30, 2004, we owned interests in 90 income-producing properties with other parties. Of those, 19 properties are included in our consolidated financial statements. We account for the other 71 properties under the equity method. Although at June 30, 2004 we had operational control, as general partner or property manager, of 59 of the 71 properties, we did not have sole control over all major decisions, such as selling or refinancing the properties without the consent of the other owners. These limitations may adversely affect our ability to sell these properties at the most advantageous time for us.

        Our real estate investment properties represent substantially all of our total consolidated assets. Real property investments are relatively illiquid. Our ability to vary our portfolio of properties in response to changes in economic and other conditions is limited. If we want to sell a property, there is no assurance that we will be able to dispose of it in the desired time period or that the sales price of a property will exceed our investment.

4

        As of October 15, 2004, there were approximately 61,792,029 outstanding units of limited partnership interests of the Operating Partnership that are exchangeable for cash or, at our option, shares of our common stock on a one-for-one basis. Although such exchanges would typically require the exchanging limited partner to recognize taxable gain on the exchange, the sale of substantial numbers of shares could adversely affect the prevailing market price for our securities. The existence of registration rights in favor of the limited partners and other parties could also adversely affect the terms upon which we can obtain additional capital in the equity markets in the future.

        Our charter contains a general restriction on the accumulation of shares in excess of 8% of the capital stock. The charter permits the Simons to own up to 18%. Ownership is determined by the lower of amount of outstanding shares, voting power or value controlled. Our Board of Directors may, by majority vote, permit exceptions to those levels in circumstances where the board determines our ability to qualify as a REIT will not be jeopardized. These restrictions on ownership may have the effect of delaying, deferring or preventing a transaction or a change in control that might otherwise be in the best interest of our stockholders. Other provisions of our charter and by-laws could have the effect of delaying or preventing a change of control even if some stockholders deem such a change to be in their best interests. These include provisions preventing holders of our common stock from acting by written consent and requiring that up to six directors in the aggregate may be elected by holders of Class B common stock and Class C common stock.

        Simon Property and certain subsidiaries of the Operating Partnership have elected to be taxed as REITs. Those subsidiaries are Retail Property Trust, a Massachusetts business trust, and Chelsea Property Group, Inc., a Maryland corporation. We anticipate that another subsidiary, Simon Kravco LLC, a Delaware limited liability company that has elected to be taxed as a corporation, will elect to be taxed as a REIT beginning with the 2004 tax year. We believe that Simon Property and these subsidiaries are organized and operated so as to qualify as REITs under the Internal Revenue Code. We intend to continue to operate them in a manner consistent with REIT status, but we cannot assure you that we will succeed in this. Qualification as a REIT requires us to satisfy annual and quarterly tests under highly technical and complex Internal Revenue Code provisions for which there are only limited judicial and administrative interpretations. For example, at least 95% of our gross income in any year must be derived from qualifying sources, and we must pay dividends to stockholders aggregating annually at least 90% of our REIT taxable income determined without regard to the dividends paid deduction and by excluding capital gains. These provisions and the applicable treasury regulations are more complicated in our case because we hold our assets in partnership form. Legislation, new regulations, administrative interpretations or court decisions could significantly change the tax laws with respect to qualification as a REIT or the federal income tax consequences of such qualification. If Simon Property or any of these subsidiaries were to fail to qualify as a REIT in any taxable year, the nonqualifying entity would be subject to federal income tax, including any applicable alternative minimum tax, on its taxable income at regular corporate rates and it would be disqualified from treatment as a REIT for four years.

There are no redemption or sinking fund provisions applicable to the common stock.

        Terms of Class B Common Stock and Class C Common Stock.    As of October 15, 2004, we had 8,000 shares of Class B common stock outstanding and 4,000 shares of Class C common stock outstanding. Holders of Class B common stock and Class C common stock:

        If we are liquidated, each outstanding share of common stock, Class B common stock and Class C common stock, including shares of Excess Common Stock, if any, will be entitled to participate pro rata in the assets remaining after payment of, or adequate provision for, all of our known debts and liabilities, subject to the right of the holders of Preferred Stock, including any Excess Preferred Stock into which shares such series has been converted, to receive preferential distributions.

        All outstanding shares of Class B common stock are held in a voting trust of which Melvin, Herbert and David Simon are the voting trustees. The holders of Class B common stock are entitled to elect four of our 13 directors. However, they will be entitled to elect only two directors if their portion of the aggregate equity interest of us, including common stock, Class B common stock and units of limited partnership interests of the Operating Partnership considered on an as-converted basis decreases to less than 50% of the amount that they owned as of August 9, 1996.

        Shares of Class B common stock may be converted at the holder's option into an equal number of shares of common stock. If the aggregate equity interest of the Simon family in us on a fully diluted basis has been reduced to less than 5%, the outstanding shares of Class B common stock convert automatically into an equal number of shares of common stock. Shares of Class B common stock also convert automatically into an equal number of shares of common stock upon the sale or transfer thereof to a person not affiliated with the Simon family. Holders of shares of common stock and Class B common stock have no sinking fund rights, redemption rights or preemptive rights to subscribe for any of our securities.

        All outstanding shares of Class C common stock are held by the DeBartolo family. Except with respect to the right to elect directors, as summarized below, each share of Class C common stock has the same rights and restrictions as a share of Class B common stock.

        The holders of Class C common stock are entitled to elect two of our 13 directors, one of whom must be an "independent director" as defined in our charter. However, they will be entitled to elect only one director if their portion of the aggregate equity interest of us, including common stock, Class B common stock and units of limited partnership interest in the Operating Partnership considered

7


on an as-converted basis, decreases to less than 50% of the amount that they owned as of August 9, 1996. Shares of Class C common stock may be converted at the holder's option into an equal number of shares of common stock. If the aggregate equity interest of the DeBartolos in us on a fully diluted basis is reduced to less than 5%, the outstanding shares of Class C common stock convert automatically into an equal number of shares of common stock. Shares of Class C common stock also convert automatically into an equal number of shares of common stock upon the sale or transfer thereof to a person not affiliated with the DeBartolos. Holders of shares of Class C common stock have no sinking fund rights, redemption rights or preemptive rights to subscribe for any of our securities.

        Under our charter, so long as any shares of both Class B common stock and Class C common stock are outstanding, the number of members of the Board of Directors shall be 13. The charter further provides that so long as any shares of Class B common stock, but no Class C common stock, are outstanding, or if any shares of Class C common stock, but no shares of Class B common stock, are outstanding, the number of members of the Board of Directors shall be nine. Finally, the charter provides that if no shares of Class B common stock or Class C common stock are outstanding, the number of members of the Board of Directors shall be fixed by the Board of Directors from time to time. Under the charter, at least a majority of the directors shall be independent directors. The charter further provides that, subject to any separate rights of holders of Preferred Stock or as described below, any vacancies on the Board of Directors resulting from death, disability, resignation, retirement, disqualification, removal from office, or other cause of a director shall be filled by a vote of the stockholders or a majority of the directors then in office provided that:

        The charter provides that, subject to the right of holders of any class or series separately entitled to elect one or more directors, if any such right has been granted, directors may be removed with or without cause upon the affirmative vote of holders of at least a majority of the voting power of all the then outstanding shares entitled to vote generally in the election of directors, voting together as a single class.

        Transfer Agent.    Mellon Investor Services LLC is the transfer agent for the shares of common stock.

Description of Series D 8% Preferred Stock

        General.    The following summary of the terms and provisions of the Series D 8% Preferred Stock does not purport to be complete and is qualified in its entirety by reference to the pertinent sections of the Certificate of Designations creating the Series D 8% Preferred Stock.

        Rank.    The Series D 8% Preferred Stock, with respect to dividend rights and rights upon liquidation, dissolution or winding up of our affairs, will rank (i) junior to all other shares of capital stock of Simon Property which, by their terms, rank senior to the Series D 8% Preferred Stock, (ii) on a parity with all other shares of preferred stock which are not, by their terms, junior or senior to the Series D 8% Preferred Stock and (iii) senior to the common stock, Class B common stock and Class C common stock and to all other shares of Simon Property capital stock which, by their terms, rank junior to the Series D 8% Preferred Stock. The Series D 8% Preferred Stock shall rank on a parity with the Series A Convertible Preferred Stock, Series A Excess Preferred Stock, Series B Convertible Preferred Stock, Series B Excess Preferred Stock, Series C Convertible Preferred Stock, Series E Cumulative Redeemable Preferred Stock, Series F Cumulative Redeemable Preferred Stock, Series G Cumulative Step-Up Premium Rate Preferred Stock, Series H Variable Rate Preferred Stock, Series I

8


Convertible Perpetual Preferred Stock and Series J Cumulative Redeemable Preferred Stock, which as of the date of this prospectus are the only authorized classes or series of our preferred stock, and any other class or series of Simon Property's capital stock that is not by its terms junior to the Series D 8% Preferred Stock.

        Dividends.    Holders of the Series D 8% Preferred Stock will be entitled to receive, when and as authorized by the board of directors, out of funds legally available for the payment of dividends, cumulative cash dividends at the rate of 8.0% of the liquidation preference per annum (equivalent to $2.40 per share per annum). Such dividends shall be payable quarterly in arrears on the last day of each March, June, September and December. Any dividend payable on the Series D 8% Preferred Stock for any partial dividend period will be computed on the basis of a 360-day year consisting of twelve 30-day months. Dividends will be payable to holders of record as they appear in the stock records of Simon Property at the close of business on the applicable record date, designated by the board of directors for the payment of dividends that is not more than 30 nor less than 5 days prior to such dividend payment date.

        Dividends on the Series D 8% Preferred Stock will accumulate whether or not we have earnings, whether or not there are funds legally available for the payment of such dividends and whether or not such dividends are authorized. Accumulated but unpaid dividends on the Series D 8% Preferred Stock shall not bear interest and holders of the Series D 8% Preferred Stock shall not be entitled to any dividends in excess of full cumulative dividends as described above.

        No dividends will be declared or paid or set apart for payment on any capital stock of Simon Property ranking, as to dividends, on a parity with or junior to the Series D 8% Preferred Stock for any period unless full cumulative dividends have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment therefor set apart for such payment on the Series D 8% Preferred Stock for all past dividend periods and the then current dividend period. When dividends are not paid in full (or a sum sufficient for such full payment is not so set apart) upon the Series D 8% Preferred Stock and the shares of each other series of preferred stock ranking on a parity as to dividends with the Series D 8% Preferred Stock, all dividends declared on the Series D 8% Preferred Stock and any other series of preferred stock ranking on a parity as to dividends with the Series D 8% Preferred Stock shall be declared pro rata so that the amount of dividends declared per share of Series D 8% Preferred Stock and such other series of preferred stock shall in all cases bear to each other the same ratio that accumulated dividends per share of Series D 8% Preferred Stock and such other series of preferred stock bear to each other.

        Except as provided in the immediately preceding paragraph, unless full cumulative dividends on the Series D 8% Preferred Stock have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment therefor set apart for such payment on the Series D 8% Preferred Stock for all past dividend periods and the then current dividend period, no dividends (other than in shares of common stock or other capital stock ranking junior to the Series D 8% Preferred Stock as to dividends and upon liquidation) shall be declared or paid or set aside for payment nor shall any other distribution be declared or made upon the common stock, Class B common stock or Class C common stock or any other capital stock of Simon Property ranking junior to or on a parity with the Series D 8% Preferred Stock as to dividends or upon liquidation, nor shall any shares of common stock, Class B common stock or Class C common stock or any other capital stock of Simon Property ranking junior to or on a parity with the Series D 8% Preferred Stock as to dividends or upon liquidation be redeemed, purchased or otherwise acquired for any consideration (or any moneys be paid or made available for a sinking fund for the redemption of such shares) by Simon Property (except by conversion into or exchange for other capital stock of Simon Property ranking junior to the Series D 8% Preferred Stock as to dividends and upon liquidation).

9


        Any dividend payment made on the Series D 8% Preferred Stock shall first be credited against the earliest accumulated but unpaid dividend due with respect to such shares which remains payable.

        Liquidation Preference.    In the event of any liquidation, dissolution or winding up of our affairs, the holders of the Series D 8% Preferred Stock will be entitled to be paid out of the assets legally available for distribution to our stockholders liquidating distributions in cash or property at its fair market value as determined by the board of directors in the amount of a liquidation preference of $30.00 per share, plus an amount equal to any accumulated and unpaid dividends, if any, thereon to the date of such liquidation, dissolution or winding up, before any distribution of assets is made to holders of common stock, Class B common stock or Class C common stock or any other capital stock ranking junior to the Series D 8% Preferred Stock as to liquidation rights. After payment of the full amount of the liquidating distributions to which they are entitled, the holders of Series D 8% Preferred Stock will have no right or claim to any of the remaining assets of Simon Property.

        In the event that, upon any such voluntary or involuntary liquidation, dissolution or winding up of our affairs, our legally available assets are insufficient to pay the amount of the liquidating distributions on the Series D 8% Preferred Stock and the corresponding amounts payable on the shares of each other series of preferred stock ranking on a parity with the Series D 8% Preferred Stock in the distribution of assets upon liquidation, then the holders of the Series D 8% Preferred Stock and any other series of preferred stock ranking on a parity with the Series D 8% Preferred Stock in the distribution of assets upon liquidation shall share ratably in any such distribution of assets in proportion to the full liquidating distributions to which they would otherwise be respectively entitled.

        Conversion.    The Series D 8% Preferred Stock will not be convertible into or exchangeable for any other property or securities of Simon Property.

        Optional Redemption.    The Series D 8% Preferred Stock shall not be redeemable prior to August 27, 2009. On and after August 27, 2009, we, at our option upon not less than 40 nor more than 70 days' written notice, may redeem the Series D 8% Preferred Stock, in whole or in part at any time or from time to time, at a redemption price of $30.00 per share, plus accumulated and unpaid dividends, if any, thereon to and including, the date fixed for redemption. The redemption price of the Series D 8% Preferred Stock (other than any portion thereof consisting of accumulated and unpaid dividends) may be paid in cash or (other than the portion thereof consisting of accrued and unpaid dividends, which shall be payable in cash) in common stock valued at the average of the closing prices of the common stock for the five consecutive trading days ending on the redemption date. Holders of Series D 8% Preferred Stock to be redeemed shall surrender such Series D 8% Preferred Stock at the place designated in the notice of redemption and shall be entitled to the redemption price upon such surrender. If notice of redemption of any Series D 8% Preferred Stock has been given and if the funds necessary for such redemption have been set apart, then from and after the redemption date dividends will cease to accumulate on such Series D 8% Preferred Stock, such stock shall no longer be deemed outstanding and all rights of the holders of such Series D 8% Preferred Stock will terminate, except the right to receive the redemption price. If fewer than all of the outstanding Series D 8% Preferred Stock are to be redeemed, the Series D 8% Preferred Stock to be redeemed shall be selected pro rata (as nearly as practicable).

        Notice of redemption will be given to the respective holders of record of the Series D 8% Preferred Stock to be redeemed at their respective addresses as they appear on the books of Simon Property. No failure to give such notice or any defect thereto or in the mailing thereof shall affect the validity of the proceedings for the redemption of any Series D 8% Preferred Stock except as to the holder to whom notice was defective or not given.

        The Series D 8% Preferred Stock does not have a stated maturity and is not subject to any sinking fund or mandatory redemption provisions.

10


        Voting Rights.    Except as indicated below or except as otherwise from time to time required by applicable law, the holders of Series D 8% Preferred Stock will have no voting rights.

        On any matter on which the Series D 8% Preferred Stock are entitled to vote (as expressly provided herein or as may be required by law), including any action by written consent, each share of Series D 8% Preferred Stock shall be entitled to one vote.

        So long as any Series D 8% Preferred Stock remains outstanding, we will not, without the affirmative vote or consent of the holders of at least a majority in liquidation preference of the Series D 8% Preferred Stock then outstanding (voting separately as a class), (i) authorize or create, or increase the authorized or issued amount of, any class or series of capital stock ranking senior to the Series D 8% Preferred Stock with respect to the payment of dividends or the distribution of assets upon liquidation, dissolution or winding up of our affairs or reclassify any authorized capital stock into such capital stock, or create, authorize or issue any obligation or security convertible into or evidencing the right to purchase any such capital stock; or (ii) amend, alter or repeal the provisions of the charter (including the Certificate of Designation of the Series D 8% Preferred Stock), so as to adversely affect the holders of the Series D 8% Preferred Stock.

        Restrictions on Transfer.    Holders of Series D 8% Preferred Stock shall be subject to certain restrictions on the number of shares of Series D 8% Preferred Stock that such holder may own in order to preserve our status as a REIT. See "Restrictions on Ownership and Transfer of Securities." Each holder of Series D 8% Preferred Stock shall upon demand be required to disclose to us in writing such information as we may request in good faith in order to determine our status as a REIT.

IMPORTANT PROVISIONS OF OUR GOVERNING DOCUMENTS AND DELAWARE LAW

Partnership Agreements

        The limited partnership agreement of the Operating Partnership contains voting requirements that limit the possibility that we will be acquired or undergo a change in control, even if some of our stockholders believe that a change would be in our and their best interests. Specifically, the partnership agreement provides that we must have the approval of the holders of a majority of the units of limited partnership interest held by limited partners in order to:

Delaware Law and Certain Charter and By-law Provisions

        Our charter and by-laws and certain provisions of the Delaware General Corporation Law may have an anti-takeover effect. These provisions may delay, defer or prevent a tender offer or takeover attempt that a stockholder would consider in its best interest. This includes an attempt that might result in a premium over the market price for the shares held by stockholders. These provisions are expected to discourage certain types of coercive takeover practices and inadequate takeover bids. They are also expected to encourage persons seeking to acquire control of us to negotiate first with our Board of Directors. We believe that the benefits of these provisions outweigh the potential disadvantages of discouraging takeover proposals because, among other things, negotiation of takeover proposals might result in an improvement of their terms.

        Delaware Anti-Takeover Law.    We are a Delaware corporation and are subject to the provisions of Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a public Delaware corporation from engaging in a "business combination" with an "interested stockholder" for three years after the time at which the person became an interested stockholder unless:

For these purposes, the term "business combination" includes mergers, asset sales and other similar transactions with an "interested stockholder." "Interested stockholder" means a person who, together with its affiliates and associates, owns, or under certain circumstances has owned within the prior three years, more than 15% of the outstanding voting stock. Although Section 203 permits a corporation to elect not to be governed by its provisions, we have not made this election.

        Advance Notice Provisions for Stockholder Nominations and Stockholder Proposals. Our by-laws establish an advance notice procedure for stockholders to make nominations of candidates for election as directors or bring other business before an annual meeting of stockholders. This procedure provides that

12

        In general, we must receive written notice of stockholder nominations to be made or business to be brought at an annual meeting not less than 120 days prior to the first anniversary of the date of the proxy statement for the previous year's annual meeting, in order for the notice to be timely. The notice must contain information concerning the person or persons to be nominated or the matters to be brought before the meeting and concerning the stockholder submitting the proposal.

        The purposes of requiring stockholders to give us advance notice of nominations and other business include the following:


        Our by-laws do not give our Board of Directors any power to disapprove stockholder nominations for the election of directors or proposals for action. However, they may have the effect of precluding a contest for the election of directors or the consideration of stockholder proposals if the proper procedures are not followed. Our by-laws may also discourage or deter a third party from soliciting proxies to elect its own slate of directors or to approve its own proposal, without regard to whether consideration of the nominees or proposals might be harmful or beneficial to us and our stockholders.

        Director Action.    Our charter and by-laws and the Delaware General Corporation Law generally require that a majority of a quorum is necessary to approve any matter to come before the Board of Directors. Certain matters, including sales of property, transactions with the Simons or the DeBartolos and certain affiliates and certain other matters, will also require approval of a majority of the independent directors on the Board of Directors.

        Director Liability Limitation and Indemnification.    Our charter provides that no director will be personally liable to us or to our stockholders for monetary damages for breach of fiduciary duty as a director. This will not, however, eliminate or limit the liability of a director for the following:

These provisions may discourage stockholders' actions against directors. Directors' personal liability for violating the federal securities laws is not limited or otherwise affected. In addition, these provisions do not affect the ability of stockholders to obtain injunctive or other equitable relief from the courts with respect to a transaction involving gross negligence on the part of a director.

        Our charter provides that we shall indemnify to the fullest extent permitted under and in accordance with Delaware law any person who was or is a party or is threatened to be made a party to

13


any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative by reason of the fact that

With respect to such persons, we shall indemnify against expenses, including attorneys' fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with the action, suit or proceeding if the following standards are met:

        The Delaware General Corporation Law provides that indemnification is mandatory where a director or officer has been successful on the merits or otherwise in the defense of any proceeding covered by the indemnification statute.

        The Delaware General Corporation Law generally permits indemnification for expenses incurred in the defense or settlement of third-party actions or action by or in right of the corporation, and for judgments in third-party actions, provided the following determination is made:

        The determination must be made by directors who were not parties to the action, or if directed by such directors, by independent legal counsel or by a majority vote of a quorum of the stockholders. Without court approval, however, no indemnification may be made in respect of any action by or in right of the corporation in which such person is adjudged liable.

        Under Delaware law, the indemnification provided by statute shall not be deemed exclusive of any rights under any by-law, agreement, vote of stockholders or disinterested directors or otherwise. In addition, the liability of officers may not be eliminated or limited under Delaware law.

        The right of indemnification, including the right to receive payment in advance of expenses, conferred by our charter is not exclusive of any other rights to which any person seeking indemnification may otherwise be entitled.

14


RESTRICTIONS ON OWNERSHIP AND TRANSFER

        Our charter contains certain restrictions on the number of shares of capital stock that individual stockholders may own. Certain requirements must be met for Simon Property to maintain its status as a REIT, including the following:

In part because we currently believe it is essential for Simon Property to maintain its status as a REIT, the provisions of its charter with respect to Excess Stock contain restrictions on the acquisition of its capital stock intended to ensure compliance with these requirements.

        Our charter provides that, subject to certain specified exceptions, no stockholder may own, or be deemed to own by virtue of the attribution rules of the Internal Revenue Code, more than the ownership limit. The ownership limit is equal to 8%, or 18% in the case of the Simons, of any class of capital stock. The ownership limit is calculated based on the lower of outstanding shares, voting power or value. The Board of Directors may exempt a person from the ownership limit if the Board of Directors receives a ruling from the Internal Revenue Service or an opinion of tax counsel that such ownership will not jeopardize Simon Property's status as a REIT.

        Anyone acquiring shares in excess of the ownership limit will lose control over the power to dispose of the shares, will not receive dividends declared and will not be able to vote the shares. In the event of a purported transfer or other event that would, if effective, result in the ownership of shares of stock in violation of the ownership limit, the transfer or other event will be deemed void with respect to that number of shares that would be owned by the transferee in excess of the ownership limit. The intended transferee of the excess shares will acquire no rights in those shares of stock. Those shares of stock will automatically be converted into shares of Excess Stock according to rules set forth in the charter.

        Upon a purported transfer or other event that results in Excess Stock, the Excess Stock will be deemed to have been transferred to a trustee to be held in trust for the exclusive benefit of a qualifying charitable organization designated by Simon Property. The Excess Stock will be issued and outstanding stock, and it will be entitled to dividends equal to any dividends which are declared and paid on the stock from which it was converted. Any dividend or distribution paid prior to the discovery by Simon Property that stock has been converted into Excess Stock is to be repaid upon demand. The recipient of the dividend will be personally liable to the trust. Any dividend or distribution declared but unpaid will be rescinded as void with respect to the shares of stock and will automatically be deemed to have been declared and paid with respect to the shares of Excess Stock into which the shares were converted. The Excess Stock will also be entitled to the voting rights as are ascribed to the stock from which it was converted. Any voting rights exercised prior to discovery by Simon Property that shares of stock were converted to Excess Stock will be rescinded and recast as determined by the trustee.

        While Excess Stock is held in trust, an interest in that trust may be transferred by the purported transferee, or other purported holder with respect to the Excess Stock, only to a person whose ownership of the shares of stock would not violate the ownership limit. Upon such transfer, the Excess Stock will be automatically exchanged for the same number of shares of stock of the same type and class as the shares of stock for which the Excess Stock was originally exchanged.

        Our charter contains provisions that are designed to ensure that the purported transferee or other purported holder of the Excess Stock may not receive in return for such a transfer an amount that

15


reflects any appreciation in the shares of stock for which the Excess Stock was exchanged during the period that the Excess Stock was outstanding. Any amount received by a purported transferee or other purported holder in excess of the amount permitted to be received must be paid over to the trust. If the foregoing restrictions are determined to be void or invalid by virtue of any legal decision, statute, rule or regulation, then the intended transferee or holder of any Excess Stock may be deemed, at the option of Simon Property, to have acted as an agent on behalf of the trust in acquiring or holding the Excess Stock and to hold the Excess Stock on behalf of the trust.

        Our charter further provides that Simon Property may purchase, for a period of 90 days during the time the Excess Stock is held by the trustee in trust, all or any portion of the Excess Stock from the original transferee-stockholder at the lesser of the following:

The 90-day period begins on the date of the violative transfer or other event if the original transferee-stockholder gives notice to Simon Property of the transfer or, if no notice is given, the date the Board of Directors determines that a violative transfer or other event has occurred.

        Our charter further provides that in the event of a purported issuance or transfer that would, if effective, result in Simon Property being beneficially owned by fewer than 100 persons, such issuance or transfer would be deemed null and void, and the intended transferee would acquire no rights to the stock.

        All certificates representing shares of any class of our stock bear a legend referring to the restrictions described above.

        All persons who own, directly or by virtue of the attribution rules of the Internal Revenue Code, more than 5%, or such other percentage as may be required by the Internal Revenue Code or regulations promulgated thereunder, of the outstanding stock must file an affidavit with Simon Property containing the information specified in the charter before January 30 of each year. In addition, each stockholder shall, upon demand, be required to disclose to Simon Property in writing such information with respect to the direct, indirect and constructive ownership of shares as the Board of Directors deems necessary to comply with the provisions of the charter or the Internal Revenue Code applicable to a REIT.

        The Excess Stock provision will not be removed automatically even if the REIT provisions of the Internal Revenue Code are changed so as to no longer contain any ownership concentration limitation or if the ownership concentration limitation is increased. In addition to preserving Simon Property's status as a REIT, the ownership limit may have the effect of precluding an acquisition of control of Simon Property without the approval of its Board of Directors.

IMPORTANT FEDERAL INCOME TAX CONSIDERATIONS

        The following summary of important federal income tax considerations associated with an investment in the securities we are registering is based on current law, is for general information only and is not tax advice. The tax treatment will vary depending on a holder's particular situation, and this discussion does not purport to deal with all aspects of taxation that may be relevant to a holder in light of his or her personal investments or tax circumstances, or to certain types of stockholders subject to special treatment under the federal income tax laws, except to the extent discussed under the headings "—Taxation of Tax-Exempt U.S. Stockholders" and "—Special Tax Considerations for Foreign Stockholders." Stockholders subject to special treatment include, without limitation:

        In addition, the summary below does not consider the effect of any foreign, state, local or other tax laws that may be applicable to holders of our common stock.

        We have received an opinion from our counsel, Baker & Daniels, that Simon Property has been organized and operated in a manner so as to qualify as a REIT and that our proposed method of operation as described in this prospectus will enable Simon Property to remain qualified as a REIT. Baker & Daniels' opinion and the information in this section are based on:

all as of the date of this prospectus. Future legislation, Treasury Regulations, administrative interpretations and practices and/or court decisions may adversely affect, perhaps retroactively, the tax considerations described herein. The statements in this prospectus are not binding on the Internal Revenue Service or any court. Thus, we can provide no assurance that Baker & Daniels' opinion and these statements will not be challenged by the Internal Revenue Service or sustained by a court if challenged by the Internal Revenue Service.

        YOU SHOULD CONSULT YOUR OWN TAX ADVISOR REGARDING THE SPECIFIC TAX CONSEQUENCES TO YOU OF BUYING, OWNING OR SELLING OUR SECURITIES.

Taxation of Simon Property

        General.    Simon Property has elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code. We believe Simon Property has been organized and operated in a manner which allows it to qualify for taxation as a REIT under the Internal Revenue Code. Simon Property intends to continue to operate in this manner. However, Simon Property's qualification and taxation as a REIT depend upon its ability to meet, through actual annual operating results, asset diversification, distribution levels and diversity of stock ownership, the various qualification tests imposed under the Internal Revenue Code. Accordingly, there is no assurance that Simon Property has operated or will continue to operate in a manner so as to qualify or remain qualified as a REIT. See "—Failure to Qualify."

        The sections of the Internal Revenue Code that relate to the qualification and operation as a REIT are highly technical and complex. The following sets forth the material aspects of the sections of the Internal Revenue Code that govern the federal income tax treatment of a REIT and its stockholders. This summary is qualified in its entirety by the applicable Internal Revenue Code provisions, relevant rules and regulations promulgated under the Internal Revenue Code, and administrative and judicial interpretations of the Internal Revenue Code.

        If Simon Property qualifies for taxation as a REIT, it generally will not be subject to federal corporate income taxes on its net income that is currently distributed to its stockholders. This treatment substantially eliminates the "double taxation," once at the corporate level when earned and once again at the stockholder level when distributed, that generally results from investment in a corporation. However, Simon Property will be subject to federal income tax as follows:

18

        Requirements for Qualification as a REIT.    The Internal Revenue Code defines a REIT as a corporation, trust or association that:

        The Internal Revenue Code provides that the first four conditions must be met during the entire taxable year and that the fifth condition must be met during at least 335 days of a taxable year of twelve months, or during a proportionate part of a taxable year of less than twelve months. The fifth and sixth conditions do not apply until after the first taxable year for which an election is made to be

19


taxed as a REIT. For purposes of the sixth condition, pension funds and certain other tax-exempt entities are treated as individuals, subject to a "look-through" exception with respect to pension funds.

        We believe that Simon Property has satisfied each of the above conditions. In addition, Simon Property's charter provides for restrictions regarding ownership and transfer of shares. These restrictions are intended to assist Simon Property in continuing to satisfy the share ownership requirements described above. These ownership and transfer restrictions are described in "Restrictions on Ownership and Transfer." These restrictions, however, may not ensure that Simon Property will, in all cases, be able to satisfy the share ownership requirements. If Simon Property fails to satisfy these share ownership requirements, its status as a REIT will terminate. However, if Simon Property complies with the rules contained in applicable Treasury Regulations that require Simon Property to ascertain the actual ownership of our shares and we do not know, or would not have known through the exercise of reasonable diligence, that Simon Property failed to meet the requirement described in the sixth condition, Simon Property will be treated as having met this requirement.

        In addition, a corporation may not elect to become a REIT unless its taxable year is the calendar year. Simon Property has and will continue to have a calendar taxable year.

        Ownership of Interests in Partnerships and Qualified REIT Subsidiaries.    In the case of a REIT which is a partner in a partnership, the Treasury Regulations provide that the REIT will be deemed to own its proportionate share of the assets of the partnership. Also, the REIT will be deemed to be entitled to the income of the partnership attributable to its proportionate share of such assets. The character of the assets and gross income of the partnership retain the same character in the hands of the REIT for purposes of Section 856 of the Internal Revenue Code, including satisfying the gross income tests and the asset tests. Thus, Simon Property's proportionate share of the assets and items of income of the Operating Partnership, including the Operating Partnership's share of these items of any partnership in which it owns an interest, are treated as Simon Property's assets and items of income for purposes of applying the requirements described in this prospectus, including the income and asset tests described below. We have included a brief summary of the rules governing the federal income taxation of partnerships and their partners below in "—Tax Aspects of the Operating Partnership and the Joint Ventures." Simon Property has direct control of the Operating Partnership and will continue to operate it consistent with the requirements for Simon Property's qualification as a REIT. However, the Operating Partnership has non-managing ownership interests in certain joint ventures. If a joint venture takes or expects to take actions which could jeopardize Simon Property's status as a REIT or subject Simon Property to tax, we may be forced to dispose of our interest in such joint venture. In addition, it is possible that a joint venture could take an action which could cause Simon Property to fail a REIT income or asset test, and that we would not become aware of such action in a time frame which would allow us to dispose of our interest in the joint venture or take other corrective action on a timely basis. In such a case, Simon Property could fail to qualify as a REIT.

        Simon Property owns 100% of the stock of several subsidiaries that are qualified REIT subsidiaries and may acquire stock of one or more new subsidiaries. A corporation will qualify as a qualified REIT subsidiary if 100% of its stock is held by Simon Property and Simon Property does not elect to treat the subsidiary as a taxable REIT subsidiary. A qualified REIT subsidiary will not be treated as a separate corporation, and all assets, liabilities and items of income, deduction and credit of a qualified REIT subsidiary will be treated as assets, liabilities and such items, as the case may be, of Simon Property for all purposes of the Internal Revenue Code, including the REIT qualification tests. For this reason, references under "Certain Federal Income Tax Considerations" to Simon Property's income and assets include the income and assets of each qualified REIT subsidiary. A qualified REIT subsidiary will not be subject to federal income tax, and our ownership of the voting stock of a qualified REIT subsidiary will not violate the restrictions against ownership of securities of any one issuer which constitute more than 10% of the value or total voting power of such issuer or more than 5% of the value of our total assets, as described below under "—Asset Tests."

20


        Ownership of Interests in Taxable REIT Subsidiaries.    The Internal Revenue Code provides that for taxable years beginning after December 31, 2000, REITs may own more than ten percent of the voting power and value of securities in taxable REIT subsidiaries. A corporation is treated as a taxable REIT subsidiary if a REIT owns stock in the corporation and the REIT and the corporation jointly elect such treatment. In the event such an election is made, any corporation of which the taxable REIT subsidiary owns 35% of the total voting power or value of the outstanding securities is also treated as a taxable REIT subsidiary.

        Although the activities and income of taxable REIT subsidiaries are subject to tax, taxable REIT subsidiaries are permitted to engage in activities that the REIT could not engage in itself. Additionally, under certain limited conditions, a REIT may receive income from a taxable REIT subsidiary that would be treated as rent. See the discussion under "—Income Tests" below. As discussed more fully under "—Asset Tests" below, not more than 20% of the fair market value of a REIT's assets can be composed of securities of taxable REIT subsidiaries and stock of a taxable REIT subsidiary is not a qualified asset for purposes of the 75% asset test.

        The amount of interest on related party debt a taxable REIT subsidiary may deduct is limited. Further, a 100% excise tax applies to any interest payments by a taxable REIT subsidiary to its affiliated REIT to the extent the interest rate is set above a commercially reasonable level. A taxable REIT subsidiary is permitted to deduct interest payments to unrelated parties without any such restrictions.

        The Internal Revenue Code allows the Internal Revenue Service to reallocate costs between a REIT and its taxable REIT subsidiary. Any deductible expenses allocated away from a taxable REIT subsidiary would increase its tax liability, and the amount of such increase would be subject to interest charges. Further, any amount by which a REIT understates its deductions and overstates those of its taxable REIT subsidiary will, subject to certain exceptions, be subject to a 100% excise tax.

        Affiliated REIT.    Simon Property owns, indirectly through the Operating Partnership, more than 99% of the outstanding stock of Retail Property Trust, a Massachusetts business trust, and Chelsea Property Group, Inc., a Maryland corporation, each of which has elected to be taxed as a REIT, and Simon Kravco LLC, a Delaware limited liability company that has elected to be taxed as a corporation and which we anticipate will elect to be taxed as a REIT beginning with the 2004 tax year. Each of these subsidiaries must meet the tests discussed above with respect to Simon Property. Each of them may be subject to tax on certain of its income as discussed above. See, "—Taxation of Simon Property—General." The failure of any or all of them to qualify as a REIT, once such status has been elected, would cause Simon Property to fail to qualify as a REIT because it would own more than 10% of the voting securities and value of an issuer that was not a REIT, a qualified REIT subsidiary or a taxable REIT subsidiary. We believe that each of these subsidiaries has been organized and operated in a manner that will permit it to qualify as a REIT.

        Income Tests.    Simon Property must satisfy two gross income requirements annually to maintain qualification as a REIT. First, in each taxable year Simon Property must derive directly or indirectly at least 75% of its gross income, excluding gross income from prohibited transactions, from investments relating to real property or mortgages on real property, including "rents from real property," dividends from other REITs, but not taxable REIT subsidiaries, and, in certain circumstances, interest, or from certain types of temporary investments. Second, each taxable year Simon Property must derive at least 95% of its gross income, excluding gross income from prohibited transactions, from these real property investments, dividends, including dividends from taxable REIT subsidiaries, interest and gain from the sale or disposition of stock or securities, or from any combination of the foregoing. The term "interest" generally does not include any amount received or accrued, directly or indirectly, if the determination of the amount depends in whole or in part on the income or profits of any person. However, an

21


amount received or accrued generally will not be excluded from the term "interest" solely by reason of being based on a fixed percentage or percentages of receipts or sales.

        Rents Simon Property receives will qualify as "rents from real property" in satisfying the gross income requirements for a REIT described above only if the following conditions are met:

        Simon Property does not and will not, and as the general partner of the Operating Partnership, will not permit the Operating Partnership to:

22

        Although members of the Simon family may own up to a 10% interest in our tenants, the Simon family does not currently own a sufficient interest to cause any of our tenants to become a related party tenant with the exception of one small tenant in Circle Center Mall in Indianapolis, Indiana. Income from a related party tenant does not qualify in satisfying our 75% income test or our 95% income test. As previously indicated, we will not lease property to any related party tenant unless we determine that the income from such tenant would not jeopardize Simon Property's status as a REIT.

        Although the Operating Partnership and other affiliates of Simon Property will perform all development, construction and leasing services for, and will operate and manage, wholly-owned properties directly without using an "independent contractor," we believe that, in almost all instances, the only services to be provided to lessees of these properties will be those usually or customarily rendered in connection with the rental of space for occupancy only. To the extent any noncustomary services are provided, such services shall generally, but not necessarily in all cases, be performed by a taxable REIT subsidiary. In any event, Simon Property intends that the amounts received by Simon Property for noncustomary services that may constitute "impermissible tenant service income" from any one property will not exceed 1% of the total amount collected from such property during the taxable year.

        A REIT is subject to a 100% excise tax on any rents it receives from tenants receiving services from the REIT's taxable REIT subsidiary to the extent such rents are above the amount that would be charged to tenants not receiving such services, unless:

        If Simon Property fails to satisfy one or both of the 75% or 95% gross income tests for any taxable year, it may nevertheless qualify as a REIT for the year if it is entitled to relief under certain provisions of the Internal Revenue Code. Generally, Simon Property may avail itself of the relief provisions if:

        It is not possible, however, to state whether in all circumstances Simon Property would be entitled to the benefit of these relief provisions. If these relief provisions do not apply to a particular set of circumstances, Simon Property will not qualify as a REIT. As discussed above in "—Taxation of Simon Property—General," even if these relief provisions apply, and we retain our status as a REIT, a tax would be imposed with respect to our excess net income. Simon Property may not always be able to maintain compliance with the gross income tests for REIT qualification despite periodic monitoring of its income.

        Asset Tests.    At the close of each quarter of Simon Property's taxable year, Simon Property also must satisfy three tests relating to the nature and diversification of its assets. First, at least 75% of the value of its total assets must be represented by real estate assets, including stock of other REITs, cash, cash items and government securities. For purposes of this test, real estate assets include stock or debt instruments that are purchased with the proceeds of a stock offering or a long-term (at least five years) public debt offering, but only for the one-year period beginning on the date Simon Property receives such proceeds. Second, not more than 25% of Simon Property's total assets may be represented by securities, other than those securities includable in the 75% asset test. Third, except with respect to taxable REIT subsidiaries and qualified REIT subsidiaries, of the investments included in the 25% asset class, the value of any one issuer's securities may not exceed 5% of the value of Simon Property's total assets, Simon Property may not own more than 10% of any one issuer's outstanding voting securities and Simon Property may not own more than 10% of the total value of any one issuer's outstanding securities other than certain securities qualifying as "straight debt".

        The Operating Partnership owns 100% of the stock of M.S. Management Associates, Inc. M.S. Management Associates, Inc. and the subsidiaries in which it owns more than 35% of the value or voting power are treated as taxable REIT subsidiaries. The value of the securities of M.S. Management Associates, Inc., including the value of its subsidiaries and the value of Simon Property's other taxable REIT subsidiaries, does not exceed 20% of the value of the total assets of Simon Property.

        After initially meeting the asset tests at the close of any quarter, Simon Property will not lose its status as a REIT for failure to satisfy the asset tests at the end of a later quarter solely by reason of changes in asset values. If Simon Property fails to satisfy the asset tests because it acquires securities or other property during a quarter, including an increase in Simon Property's interests in assets held, directly or indirectly, by the Operating Partnership, Simon Property can cure this failure by disposing of sufficient nonqualifying assets within 30 days after the close of that quarter. We believe we have maintained and will continue to maintain adequate records of the value of Simon Property's assets to ensure compliance with the asset tests and to take such other actions within the 30 days after the close of any quarter as may be required to cure any noncompliance. If we failed to cure noncompliance with the asset tests within this time period, Simon Property would cease to qualify as a REIT.

        Annual Distribution Requirements.    To maintain qualification as a REIT, Simon Property is required to distribute dividends, other than capital gain dividends, to its stockholders in an amount at least equal to the difference between (1) the sum of 90% of its "REIT taxable income," computed without regard to the dividends paid deduction and net capital gain, and 90% of its after tax net income, if any, from foreclosure property, and (2) the amount of certain items of noncash income, i.e., income attributable to leveled stepped rents, original issue discount on purchase money debt, or a like-kind exchange that is later determined to be taxable, in excess of 5% of "REIT taxable income." In addition, if Simon Property is allocated any built-in gain as a result of the disposition during the restriction period of any asset subject to the built-in gain rules, then Simon Property will be required to distribute at least 90% of such built-in gain less the amount of tax incurred by Simon Property as a result of such gain.

        Dividends declared and payable to stockholders of record in the last three months of any year must be paid by the end of January of the year following the taxable year in which the dividends were declared, unless they were declared before the due date of Simon Property's tax return for the taxable year in which they were declared. If they were declared before such due date, whether declared in the last three months of the year or otherwise, they must be distributed on or before the end of January of the following taxable year, or, if later, the earlier of the first regular dividend payment after the declaration or the close of the taxable year following the taxable year to which they relate. The amount distributed must not be preferential. This means that every stockholder of the class of stock to which a distribution is made must be treated the same as every other stockholder of that class, and no class of stock may be treated otherwise than in accordance with its dividend rights as a class. We believe Simon

24


Property has made and will continue to make timely distributions sufficient to satisfy these annual distribution requirements.

        We expect that Simon Property's REIT taxable income will be less than its cash flow due to the allowance of depreciation and other non-cash charges in computing REIT taxable income. Accordingly, we anticipate that Simon Property will generally have sufficient cash or liquid assets to satisfy the distribution requirements described above. However, from time to time, Simon Property may not have sufficient cash or other liquid assets to meet these distribution requirements due to timing differences between the actual receipt of income and actual payment of deductible expenses, and the inclusion of income and deduction of expenses in arriving at its taxable income. If these timing differences occur, in order to meet the distribution requirements, Simon Property may need to arrange for short-term, or possibly long-term, borrowings or need to pay dividends in the form of taxable stock dividends. To the extent Simon Property satisfies the distribution requirements but distributes less than 100% of the net capital gain or 100% of its REIT taxable income, Simon Property will be subject to tax on such income at regular corporate rates.

        Under certain circumstances, we may be able to rectify a failure to meet the distribution requirement for a year by paying "deficiency dividends" to stockholders in a later year, which may be included in Simon Property's deduction for dividends paid for the earlier year. Thus, Simon Property may be able to avoid being taxed on amounts distributed as deficiency dividends. However, Simon Property will be required to pay interest based upon the amount of any deduction taken for deficiency dividends.

        Furthermore, Simon Property would be subject to a 4% excise tax on the excess of the required distribution over the amounts actually distributed if we should fail to distribute during each calendar year, or in the case of distributions with declaration and record dates falling in the last three months of the calendar year, by the end of January immediately following such year, at least the sum of 85% of Simon Property's REIT ordinary income for such year, 95% of its REIT capital gain income for the year and any undistributed taxable income from prior periods. Any REIT taxable income and net capital gain on which corporate income tax is imposed for any year is treated as an amount distributed during that year for purposes of calculating such tax.

        Property Transfers.    Any gain realized by Simon Property on the sale of any property held as inventory or other property held primarily for sale to customers in the ordinary course of business, including Simon Property's share of any such gain realized by the Operating Partnership, either directly or through its subsidiary partnerships, will be treated as income from a prohibited transaction that is subject to a 100% penalty tax. This prohibited transaction income may also adversely affect Simon Property's ability to satisfy the income tests for qualification as a REIT. Under existing law, whether property is held as inventory or primarily for sale to customers in the ordinary course of a trade or business is a question of fact that depends on all the facts and circumstances surrounding the particular transaction. The Operating Partnership intends to hold its properties for investment with a view to long-term appreciation, to engage in the business of acquiring, developing and owning its properties and to make occasional sales of the properties as are consistent with the Operating Partnership's investment objectives. However, the Internal Revenue Service may successfully contend that some or all of the sales made by the Operating Partnership or its subsidiaries are prohibited transactions. We would be subject to the 100% penalty tax on our allocable share of the gains resulting from any such sales.

Failure to Qualify

        If Simon Property fails to qualify for taxation as a REIT in any taxable year, and the relief provisions do not apply, Simon Property will be subject to tax, including any applicable alternative minimum tax, on its taxable income at regular corporate rates. Distributions to stockholders in any year

25


in which Simon Property fails to qualify will not be deductible by Simon Property and Simon Property will not be required to distribute any amounts to its stockholders. As a result, Simon Property's failure to qualify as a REIT would reduce the cash available for distribution to Simon Property stockholders. In addition, if Simon Property fails to qualify as a REIT, all distributions to stockholders will be taxable as ordinary income to the extent of Simon Property's current and accumulated earnings and profits, and subject to certain limitations of the Internal Revenue Code, corporate distributees may be eligible for the dividends received deduction. Unless entitled to relief under specific statutory provisions, Simon Property will also be disqualified from taxation as a REIT for the four taxable years following the year during which it lost its qualification. It is not possible to state whether in all circumstances we would be entitled to this statutory relief.

Tax Aspects of the Operating Partnership and the Joint Ventures

        General.    Substantially all of our income-producing properties are held directly or indirectly through the Operating Partnership. In addition, the Operating Partnership holds certain of its investments indirectly through joint ventures. In general, partnerships are "pass-through" entities which are not subject to federal income tax. Rather, partners are allocated their proportionate shares of the items of income, gain, loss, deduction and credit of a partnership, and are potentially subject to tax thereon, without regard to whether the partners receive a distribution from the partnership. Simon Property includes in its income its proportionate share of the foregoing partnership items for purposes of the various REIT income tests and in the computation of Simon Property's REIT taxable income. Moreover, for purposes of the REIT asset tests, we will include our proportionate share of assets held by the Operating Partnership and joint ventures. See "—Taxation of Simon Property."

        Entity Classification.    Simon Property's interests in the Operating Partnership and the subsidiary partnerships, including joint ventures, involve special tax considerations, including the possibility of a challenge by the Internal Revenue Service of the status of the Operating Partnership or a subsidiary partnership as a partnership as opposed to an association taxable as a corporation for federal income tax purposes. If the Operating Partnership or a subsidiary partnership were treated as an association, it would be taxable as a corporation and therefore be subject to an entity-level tax on its income. In such a situation, the character of Simon Property's assets and items of gross income would change and preclude Simon Property from satisfying the asset tests and possibly the income tests. See "—Taxation of Simon Property—Asset Tests" and "—Income Tests". This, in turn, would prevent Simon Property from qualifying as a REIT. See "—Failure to Qualify" for a discussion of the effect of our failure to meet these tests for a taxable year. In addition, a change in the Operating Partnership's or a partnership's status for tax purposes might be treated as a taxable event. If so, Simon Property might incur a tax liability without any related cash distributions.

        Treasury Regulations that apply for tax periods beginning on or after January 1, 1997 provide that a domestic business entity not otherwise classified as a corporation and which has at least two members will be taxed as a partnership for federal income tax purposes unless it elects to be treated as a corporation or it was in existence prior to January 1, 1997, and it reported its income as a corporation under the entity classification Treasury Regulations in effect prior to this date. In addition, such an entity which did not exist, or did not claim a classification, prior to January 1, 1997, will be classified as a partnership for federal income tax purposes unless it elects otherwise. The Operating Partnership and each of the subsidiary partnerships have claimed classification as a partnership under the final Treasury Regulations, and, as a result, we believe such partnerships will be classified as partnerships for federal income tax purposes.

        The Treasury Regulations also provide that certain specified foreign entities are taxed as corporations. Foreign entities with two or more members are taxed as partnerships if (a) at least one of the members has unlimited liability for the liabilities of the entity or (b) the entity elects to be taxed as a partnership. Each foreign entity having two or more members in which Simon Property is treated as

26


an owner for tax purposes has elected to be taxed as a partnership or as a taxable REIT subsidiary. Certain foreign entities with only one member are also taxed as corporations unless the entity elects to have its existence as separate from its member disregarded for tax purposes. Each foreign entity in which Simon Property is the only member has elected to be treated as a disregarded entity.

        Allocations of Operating Partnership Income, Gain, Loss and Deduction.    A partnership is not a taxable entity for federal income tax purposes. Rather, a partner is required to take into account its allocable share of a partnership's income, gains, losses, deductions and credits for any taxable year of the partnership ending within or with the taxable year of the partner, without regard to whether the partner has received or will receive any distributions from the partnership. Although a partnership agreement will generally determine the allocation of income and losses among partners, such allocations will be disregarded for tax purposes under section 704(b) of the Internal Revenue Code if they do not comply with the provisions of section 704(b) of the Internal Revenue Code and the Treasury Regulations promulgated thereunder as to substantial economic effect.

        If an allocation is not recognized for federal income tax purposes because it does not have substantial economic effect, the item subject to the allocation will be reallocated in accordance with the partners' interests in the partnership, which will be determined by taking into account all of the facts and circumstances relating to the economic arrangement of the partners with respect to such item. The allocations of taxable income and loss of the Operating Partnership and subsidiary partnerships are intended to comply with the requirements of section 704(b) of the Internal Revenue Code and the Treasury Regulations promulgated thereunder.

Taxation of Taxable U.S. Stockholders

        As used below, the term "U.S. stockholder" means a holder of shares of common stock who, for United States federal income tax purposes, is:

        Notwithstanding the preceding sentence, to the extent provided in Treasury Regulations, certain trusts in existence on August 20, 1996, and treated as United States persons prior to this date that elect to continue to be treated as United States persons, shall also be considered U.S. stockholders.

        Distributions Generally.    As long as Simon Property qualifies as a REIT, distributions out of its current or accumulated earnings and profits, other than capital gain dividends discussed below, will constitute dividends taxable to its taxable U.S. stockholders as ordinary income. These distributions will not be eligible for the dividends-received deduction in the case of U.S. stockholders that are corporations. For purposes of determining whether distributions to holders of common stock are out of current or accumulated earnings and profits, Simon Property's earnings and profits will be allocated first to the outstanding preferred stock and then to the common stock.

        To the extent that Simon Property makes distributions in excess of its current and accumulated earnings and profits, these distributions will be treated first as a tax-free return of capital to each U.S. stockholder. This treatment will reduce the adjusted basis, but not below zero, which each U.S.

27


stockholder has in his shares of stock for tax purposes by the amount of the distribution in excess of current and accumulated earnings and profits. Such distributions in excess of a U.S. stockholder's adjusted basis in his shares will be taxable as capital gains, provided that the shares have been held as a capital asset, and will be taxable as long-term capital gain if the shares have been held for more than one year. Dividends declared in October, November, or December of any year and payable to a stockholder of record on a specified date in any of these months shall be treated as both paid by Simon Property and received by the stockholder on December 31 of that year, provided Simon Property actually pays the dividend on or before January 31 of the following calendar year. Stockholders may not include in their own income tax returns any of Simon Property's net operating losses or capital losses.

        Capital Gain Dividends.    Dividends to U.S. stockholders that are properly designated by Simon Property as capital gain dividends will be treated as long-term capital gain to the extent they do not exceed Simon Property's actual net capital gain for the taxable year without regard to the period for which the stockholder has held his stock. Dividends designated as capital gains will be taxed to each individual at a rate up to 25% depending on the tax characteristics of the assets which produced such gain and such individual's situation. Corporate stockholders, however, may be required to treat up to 20% of certain capital gain dividends as ordinary income.

        Simon Property may elect to retain and pay income tax on some or all of its undistributed net capital gains, in which case Simon Property's stockholders will include such retained amount in their income. In that event, the stockholders would be entitled to a tax credit or refund in the amount of the tax paid by Simon Property on the undistributed gain allocated to the stockholders, and the stockholders would be entitled to increase their tax basis by the amount of undistributed capital gains allocated to such stockholders reduced by the amount of the credit.

        Passive Activity Losses and Investment Interest Limitations.    Dividends that Simon Property pays and gain arising from the sale or exchange by a U.S. stockholder of shares will not be treated as passive activity income. As a result, U.S. stockholders generally will not be able to apply any "passive losses" against this income or gain. Dividends, to the extent they do not constitute a return of capital, generally will be treated as investment income for purposes of computing the investment interest limitation. Gain arising from the sale or other disposition of shares, however, will not be treated as investment income except to the extent the stockholder elects to reduce the amount of his net capital gain eligible for the capital gains rate.

Dispositions of Shares

        A U.S. stockholder will recognize gain or loss on the sale or exchange of shares of common stock to the extent of the difference between the amount realized on such sale or exchange and the holders' adjusted tax basis in such shares. Such gain or loss generally will constitute long-term capital gain or loss if the holder has held such shares for more than one year. Individual taxpayers are generally subject to a maximum tax rate of 15% on long-term capital gain from the sale of securities, but shareholders subject to the alternative minimum tax may be taxed at a rate of 25% on some or all of their long-term capital gain. Losses incurred on the sale or exchange of shares of common stock held for six months or less, after applying certain holding period rules, however, will generally be deemed long-term capital loss to the extent of any long-term capital gain dividends received by the U.S. stockholder and undistributed capital gains allocated to such U.S. stockholder with respect to such shares.

Taxation of Tax-Exempt U.S. Stockholders

        The Internal Revenue Service has ruled that amounts distributed as dividends by a REIT do not constitute unrelated business taxable income when received by a tax-exempt pension trust and certain

28


other tax-exempt entities. Based on that ruling, provided that a tax-exempt stockholder, except certain tax-exempt stockholders described below, has not held its shares as "debt financed property" within the meaning of the Internal Revenue Code and the shares are not otherwise used in an unrelated trade or business, dividend income from us will not be unrelated business taxable income to a tax-exempt stockholder. Generally, "debt financed property" means shares of common stock, the acquisition of which was financed through a borrowing by the tax-exempt stockholder. Similarly, income from the sale of shares will not constitute unrelated business taxable income unless a tax-exempt stockholder has held its shares as "debt financed property" within the meaning of the Internal Revenue Code or has used the shares in its unrelated trade or business.

        For tax-exempt stockholders which are social clubs, voluntary employee benefit associations, supplemental unemployment benefit trusts, and qualified group legal services plans exempt from federal income taxation under Internal Revenue Code Section 501(c)(7), (c)(9), (c)(17) and (c)(20), respectively, income from an investment in Simon Property's shares will constitute unrelated business taxable income unless the organization is able to properly deduct amounts set aside or placed in reserve for certain purposes so as to offset its dividend income. These prospective investors should consult their own tax advisors concerning these "set aside" and reserve requirements.

        Notwithstanding the above, however, a portion of the dividends paid by a "pension held REIT" are treated as unrelated business taxable income as to certain types of trusts which hold more than 10% (by value) of the interests in the REIT. A REIT will not be a "pension held REIT" if it is not "predominantly held" by tax-exempt pension trusts. We do not anticipate that Simon Property will be predominantly held by tax-exempt pension trusts within the meaning of the Internal Revenue Code and accordingly, believe that dividends paid by Simon Property to tax-exempt pension trusts should not be treated as unrelated business taxable income.

Special Tax Considerations For Foreign Stockholders

        The rules governing United States federal income taxation of non-U.S. stockholders, including non-resident alien individuals, foreign corporations, foreign partnerships and foreign trusts and estates, are complex, and the following discussion is intended only as a summary of such rules. Prospective non-U.S. stockholders should consult with their own tax advisors to determine the impact of federal, state and local income tax laws on an investment in Simon Property, including any reporting requirements, as well as the tax treatment of such an investment under their home country laws.

        In general, non-U.S. stockholders will be subject to regular United States federal income tax with respect to their investment in Simon Property if such investment is "effectively connected" with the non-U.S. stockholder's conduct of a trade or business in the United States. A corporate non-U.S. stockholder that receives income that is, or is treated as, effectively connected with a United States trade or business may also be subject to the branch profits tax under section 884 of the Internal Revenue Code, which is payable in addition to regular United States corporate income tax. The following discussion will apply to non-U.S. stockholders whose investment in Simon Property is not so effectively connected. Simon Property expects to withhold United States income tax, as described below, on the gross amount of any distributions paid to a non-U.S. stockholder unless (i) the non-U.S. stockholder files an Internal Revenue Service Form W-8ECI with Simon Property claiming that the distribution is "effectively connected" or (ii) certain other exceptions apply.

        A distribution by Simon Property that is not attributable to gain from the sale or exchange by Simon Property of a United States real property interest and that is not designated by Simon Property as a capital gain dividend will be treated as an ordinary income dividend to the extent made out of current or accumulated earnings and profits. Generally, an ordinary income dividend will be subject to tax at the rate of 30% of the gross amount of the distribution unless such tax is reduced or eliminated by an applicable tax treaty. A distribution in cash in excess of Simon Property's earnings and profits will

29


be treated first as a return of capital that will reduce a non-U.S. stockholder's basis in its shares of Simon Property stock, but not below zero, and then as gain from the disposition of such shares, the tax treatment of which is described under the rules discussed below with respect to dispositions of shares. Simon Property is required to withhold from distributions to non-U.S. stockholders, and to remit to the Internal Revenue Service, 30% of the amount of ordinary dividends. A distribution in excess of Simon Property's earnings and profits may be subject to 30% dividend withholding if, at the time of the distribution, it cannot be determined whether the distribution will be in an amount in excess of Simon Property's current or accumulated earnings and profits. Any amount not designated as a capital gain dividend or return of basis will be subject to the tax treatment and withholding described below.

        Distributions by Simon Property that are attributable to gain from the sale or exchange of a United States real property interest will be taxed to a non-U.S. stockholder under the Foreign Investment in Real Property Tax Act of 1980 ("FIRPTA"). Under FIRPTA, distribution amounts not subject to the tax treatment described in the preceding paragraph are taxed to a non-U.S. stockholder as if such distributions were gains "effectively connected" with a United States trade or business. Accordingly, a non-U.S. stockholder will be taxed at the normal capital gain rates applicable to a U.S. stockholder on such amounts, subject to any applicable alternative minimum tax and a special alternative minimum tax in the case of nonresident alien individuals. Distributions subject to FIRPTA may also be subject to a 30% branch profits tax in the hands of a corporate non-U.S. stockholder that is not entitled to treaty exemption.

        Simon Property will be required to withhold from distributions subject to FIRPTA, and remit to the Internal Revenue Service, 35% of designated capital gain dividends, or, if greater, 35% of the amount of any distributions that could be designated as capital gain dividends. In addition, if Simon Property designates prior distributions as capital gain dividends, subsequent distributions, up to the amount of such prior distributions not withheld against, will be treated as capital gain dividends for purposes of withholding. It should be noted that the 35% withholding tax rate on capital gain dividends currently corresponds to the maximum income tax rate applicable to corporations, but it is higher than the maximum rate on capital gains of individuals.

        Tax treaties may reduce Simon Property's withholding obligations. If the amount withheld by Simon Property with respect to a distribution exceeds the non-U.S. stockholder's tax liability, the non-U.S. stockholder may file for a refund of such excess from the Internal Revenue Service.

        Unless Simon Property shares constitute a "United States real property interest" within the meaning of FIRPTA or are effectively connected with a U.S. trade or business, a sale of such shares by a non-U.S. stockholder generally will not be subject to United States taxation. Simon Property shares will not constitute a United States real property interest if Simon Property is a "domestically controlled REIT." A domestically controlled REIT is a REIT in which at all times during a specified testing period less than 50% in value of its shares is held directly or indirectly by non-U.S. stockholders. We believe that Simon Property is a domestically controlled REIT, and therefore that the sale of shares in Simon Property will not be subject to taxation under FIRPTA. However, because Simon Property shares are publicly traded, no assurance can be given that Simon Property is or will continue to be a domestically controlled REIT. Notwithstanding the foregoing, capital gain not subject to FIRPTA will be taxable to a non-U.S. stockholder if the non-U.S. stockholder is a nonresident alien individual who is present in the United States for 183 days or more during the taxable year and certain other conditions apply, in which case the nonresident alien individual will be subject to a 30% tax on such individual's capital gains. If Simon Property did not constitute a domestically controlled REIT, whether a non-U.S. stockholder's sale of shares of Simon Property would be subject to tax under FIRPTA as a sale of a United States real property interest would depend on whether the shares were "regularly traded" as defined by applicable Treasury Regulations on an established securities market, e.g., the New York Stock Exchange, on which the shares of Simon Property common stock are listed and on the size of the selling stockholder's interest in Simon Property, i.e., 5% or less ownership. If the gain on the

30


sale of Simon Property's shares were subject to taxation under FIRPTA, the non-U.S. stockholder would be subject to the same treatment as a U.S. stockholder with respect to such gain, subject to applicable alternative minimum tax and a special alternative minimum tax in the case of nonresident alien individuals. In any event, a purchaser of shares of Simon Property common stock from a non-U.S. stockholder will not be required under FIRPTA to withhold on the purchase price if the purchased shares are "regularly traded" on an established securities market or if Simon Property is a domestically controlled REIT. Otherwise, under FIRPTA, the purchaser of shares of common stock may be required to withhold ten percent of the purchase price and remit such amount to the Internal Revenue Service.

Information Reporting Requirement And Backup Withholding Tax

        Simon Property will report to its U.S. stockholders and the Internal Revenue Service the amount of distributions paid during each calendar year and the amount of tax withheld, if any. Under certain circumstances, U.S. stockholders may be subject to backup withholding. Backup withholding will apply only if the holder

Backup withholding will not apply with respect to payments made to certain exempt recipients, such as corporations and tax-exempt organizations. U.S. stockholders should consult their own tax advisors regarding their qualification for exemption from backup withholding and the procedure for obtaining such an exemption. Backup withholding is not an additional tax. Rather, the amount of any backup withholding with respect to a payment to a U.S. stockholder will be allowed as a credit against such U.S. stockholder's United States federal income tax liability and may entitle such U.S. stockholder to a refund, provided that the required information is furnished to the Internal Revenue Service.

        Additional issues may arise pertaining to information reporting and backup withholding with respect to non-U.S. stockholders. For example, we may be required to withhold a portion of capital gain distributions to any stockholders who fail to certify their foreign status to us on Form W-8BEN. Non-U.S. stockholders should consult their tax advisors with respect to any such information reporting and backup withholding requirements.

State And Local Tax Considerations

        Simon Property is, and its stockholders may be, subject to state or local taxation in various state or local jurisdictions where Simon Property, its affiliates and its stockholders transact business or reside. The state and local tax treatment of Simon Property and its stockholders may not conform to the federal income tax consequences discussed above. Consequently, prospective stockholders should consult their own tax advisors regarding the effect of state and local tax laws on their investment in Simon Property shares.

31


Possible Federal Tax Developments

        The rules dealing with federal income taxation are constantly under review by the Internal Revenue Service, the Treasury Department and Congress. New federal tax legislation or other provisions may be enacted into law or new interpretations, rulings or Treasury Regulations could be adopted, all of which could affect the taxation of the Companies and their stockholders. No prediction can be made as to the likelihood of passage of any new tax legislation or other provisions either directly or indirectly affecting us or our stockholders. Consequently, the tax treatment described herein may be modified prospectively or retroactively by legislative action.

SELLING STOCKHOLDERS

        The shares covered by this prospectus are being registered pursuant to provisions of the limited partnership agreement of the Operating Partnership and a registration rights agreement by and among Simon Property, certain selling stockholders and other persons. Except as otherwise indicated, the number of shares beneficially owned is determined under rules promulgated by the SEC, and the information may not represent beneficial ownership for any other purpose. Except as indicated otherwise in the table below, each selling stockholder has sole voting power and disposition power with respect to all shares listed as owned by such selling stockholder. At October 15, 2004, there were 219,051,818 shares of common stock outstanding and 1,156,039 shares of Series D 8% Preferred Stock outstanding.

        We do not know when or in what amounts the selling stockholders may offer shares for sale. The selling stockholders may elect not to sell any or all of the shares offered by this prospectus. Because the selling stockholders may offer all or some of the shares pursuant to this offering, and because there are currently no agreements, arrangements or understandings with respect to the sale of any of the shares that will be held by the selling stockholders after completion of the offering, we cannot estimate the number of the shares that will be held by the selling stockholders after completion of the offering. However, for purposes of this table, we have assumed that, after completion of the offering, none of the shares covered by the prospectus will be held by the selling stockholders.

        The following tables set forth, to our knowledge, certain information about the selling stockholders as of October 15, 2004.

PLAN OF DISTRIBUTION

        The shares covered by this prospectus may be offered and sold from time to time by the selling stockholders. The term "selling stockholders" includes pledgees, donees, transferees or other successors in interest selling shares received after the date of this prospectus from one of the selling stockholders as a pledge, gift or other non-sale related transfer. To the extent required, this prospectus may be amended and supplemented from time to time to describe a specific plan of distribution.

        The selling stockholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. These sales may be made at a fixed price or prices, which may be changed or (for our common stock) at prices on the New York Stock Exchange and under terms then prevailing or at prices related to the then current market price. Sales may also be made in negotiated transactions at negotiated prices, including pursuant to one or more of the following methods:

        In connection with distributions of the shares or otherwise, the selling stockholders may:

        In addition, any shares that qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this prospectus.

        In effecting sales, broker-dealers or agents engaged by the selling stockholders may arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the selling stockholders, in amounts to be negotiated immediately prior to the sale.

        In offering the shares covered by this prospectus, the selling stockholders, and any broker-dealers and any other participating broker-dealers who execute sales for the selling stockholders may be deemed to be "underwriters" within the meaning of the Securities Act in connection with these sales. Any profits realized by the selling stockholders and the compensation of such broker-dealers may be deemed to be underwriting discounts and commissions.

36


        In order to comply with the securities laws of certain states, the shares must be sold in those states only through registered or licensed brokers or dealers. In addition, in certain states the shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

        We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the selling stockholders and their affiliates. In addition, we will make copies of this prospectus available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

        At the time a particular offer of shares is made, if required, a prospectus supplement will be distributed that will set forth:

        We have agreed to indemnify the selling stockholders against certain liabilities, including certain liabilities under the Securities Act.

        We have agreed with the selling stockholders to keep the Registration Statement of which this prospectus constitutes a part effective until the earlier of such time as:

INFORMATION NOT REQUIRED IN PROSPECTUS

Item. 14.    Other Expenses of Issuance and Distribution.

        The expenses (not including underwriting commissions and fees) of issuance and distribution of the securities are estimated to be:

 
    
  
Registration Fee   $ 10,529  
   
 
Printing Expenses     15,000 *
Accounting Fees and Expenses     30,000 *
Attorneys' Fees and Expenses     25,000 *
Miscellaneous Expenses     5,000 *
   
 
  Total   $ 85,529 *
   
 
*
Estimated.

Item 15.    Indemnification of Directors and Officers.

        The Registrant's officers and directors are indemnified under Delaware law, the Registrant's Charter and the Partnership Agreement of Simon Property Group, L.P. (the "Operating Partnership") against certain liabilities. The Delaware General Corporation Law ("DGCL") generally permits a corporation to indemnify its directors and officers, among others, against expenses, judgments, fines and amounts paid in settlement actually or reasonably incurred by them in the defense or settlement of third-party actions or action by or in right of the corporation, and for judgments in third party actions provided there is a determination by directors who were not parties to the action, or if directed by such directors, by independent legal counsel or by a majority vote of a quorum of the stockholders, that the person seeking indemnification acted in good faith and in a manner reasonably believed to be in, or not opposed to, the interests of the corporation, and in a criminal proceeding, that the person had no reason to believe his or her conduct to be unlawful. Without court approval, however, no indemnification may be made in respect of any action by or in right of the corporation in which such person is adjudged liable. The DGCL states that the indemnification provided by statute shall not be deemed exclusive of any rights under any by-law, agreement, vote of stockholders or disinterested directors or otherwise. In addition, the liability of officers may not be eliminated or limited under Delaware law.

        The Registrant's Charter contain a provision limiting the liability of directors and officers to the Registrant and its stockholders to the fullest extent permitted under and in accordance with the laws of the State of Delaware. The Registrant's Charter provides that the directors will not be personally liable to the corporation or to its stockholders for monetary damages for breach of fiduciary duty as a director; provided, however, that such provision will not eliminate or limit the liability of a director for (i) any breach of the director's duty of loyalty to the corporation and its stockholders; (ii) acts or omissions not in good faith; (iii) any transaction from which the director derived an improper personal benefit; or (iv) any matter in respect of which such director would be liable under Section 174 of the DGCL. The personal liability of a director for violation of the federal securities laws is not limited or otherwise affected. In addition, these provisions do not affect the ability of stockholders to obtain injunctive or other equitable relief from the courts with respect to a transaction involving gross negligence on the part of a director. No amendment of the Registrant's Charter shall limit or eliminate the right to indemnification provided with respect to acts or omissions occurring prior to such amendment or repeal. The Registrant's By-Laws contain provisions which implement the indemnification provisions of the Registrant's Charter.

II-1


        The Partnership Agreement of the Operating Partnership provides for indemnification of the officers and directors of each general partner of the Operating Partnership to the same extent indemnification is provided to officers and directors of the Registrant in its Charter, and limits the liability of such general partners and their officers and directors to the Operating Partnership and their partners to the same extent liability of officers and directors of the Registrant to the Registrant and its stockholders is limited under the Registrant's Charter.

        The Registrant has entered into indemnification agreements with each of the Registrant's directors and officers. The indemnification agreements require, among other things, that the Registrant indemnify its directors and officers to the fullest extent permitted by law, and advance to the directors and officers all related expenses, subject to reimbursement if it is subsequently determined that indemnification is not permitted. The Registrant also must indemnify and advance all expenses incurred by directors and officers seeking to enforce their rights under the indemnification agreements, and cover each director and officer if the Registrant obtains directors' and officers' liability insurance.

        In addition, the Registrant has a directors' and officers' liability and company reimbursement policy that insures against certain liabilities, including liabilities under the Securities Act, subject to applicable retentions.

Item 16.    Exhibits.

        The list of exhibits is incorporated by reference to the Exhibit Index on page E-1.

Item 17.    Undertakings.

        Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.

Exhibit 4.3

REGISTRATION RIGHTS AGREEMENT

        REGISTRATION RIGHTS AGREEMENT, dated as of August 27, 1999 (the "Agreement"), is by and among Simon Property Group, Inc. (the "Company") and the persons set forth on Schedule A (the "Rights Holders"). The Rights Holders and their respective successors-in-interest and permitted assigns are hereinafter sometimes referred to as the "Holders."

R E C I T A L S:

        On September 24, 1998, the Company and certain holders of Partnership Units (as defined below in Section 11.4) (the "Priority Holders") of Simon Property Group, L.P., a Delaware limited partnership (the "Operating Partnership"), entered into a Registration Rights Agreement.

        The Operating Partnership has issued to the Rights Holders units in the Operating Partnership consisting of common units ("Common Units"), 7.00% Cumulative Convertible Preferred Units ("7% Preferred Units") and 8.00% Cumulative Redeemable Preferred Units ("8% Preferred Units" and, together with the 7% Preferred Units and New 8% Preferred Units, as defined below, the "Preferred Units", and the Common Units, together with Preferred Units, the "Units").

        Under the Sixth Amended and Restated Agreement of Limited Partnership of the Operating Partnership dated as of September 24, 1998, as amended and supplemented to date (the "Partnership Agreement"), the Holders have the right to exchange all or any portion of their 7% Preferred Units (i) at any time after April 27, 2004, for shares ("7% Preferred Shares") of the Company's 7.00% Cumulative Convertible Preferred Stock (the "7% Preferred Stock"), (ii) under certain circumstances after April 27, 2004, for Common Units. In addition, under certain circumstances the Holders (or the successor holders, as the case may be) may require the Operating Partnership to repurchase such Holders' 7% Preferred Units, with the purchase price to be paid in cash and/or Common Shares (as defined below), all as set forth in the Partnership Agreement.

        Under the Partnership Agreement the Holders have the right to exchange all or any portion of their 8% Preferred Units at any time after April 27, 2004, for shares ("8% Preferred Shares" and, together with the 7% Preferred Shares, "Preferred Shares") of the Company's 8.00% Cumulative Redeemable Preferred Stock (the "8% Preferred Stock"). At any time after April 27, 2009, the Operating Partnership has the right to redeem the 8% Preferred Units with payment of a redemption price consisting (other than the portion thereof consisting of accrued and unpaid distributions, which is payable in cash) of new preferred units ("New 8% Preferred Units") or Common Units, at the election of the Operating Partnership. In addition, under certain circumstances the Holders (or the successor holders, as the case may be) may require the Operating Partnership to repurchase such Holders' 8% Preferred Units, with the purchase price to be paid in cash and/or Common Shares, all as set forth in the Partnership Agreement.

        Under the Partnership Agreement holders of Common Units have the right to exchange all or any portion of their Common Units for shares ("Common Shares" and together with Preferred Shares, "Shares") of the Company's common stock, par value $.0001 per share (which are paired with a beneficial interest in shares of common stock, par value $.0001 per share, of SPG Realty Consultants, Inc. ("SPG, Realty")) (the "Common Stock"), or cash, at the election of the Company and SPG Realty.

        Except as provided herein, any Shares issued upon such exchange of Preferred Units for Preferred Shares or Common Units for Common Shares will not be registered under the Securities Act of 1933, as amended (the "Securities Act").

1


        The Company has agreed to provide certain registration rights with respect to the Shares held or to be held by the Holders.

        In consideration of the mutual covenants and agreements set forth herein and for good and valuable consideration, the receipt of which is hereby acknowledged, the parties hereto agree as follows:

        1.    Securities Subject to this Agreement.    The securities entitled to the benefits of this Agreement are (a) the Preferred Shares or Common Shares issued upon exchange or repurchase of the Preferred Units, (b) the Common Shares issued by the Company to the Holders upon exchange of the Common Units and (c) the Common Shares issued upon conversion of the Preferred Shares (collectively, the "Registrable Securities") but, with respect to any particular Registrable Security, only so long as it continues to be a Registrable Security. Registrable Securities shall include any securities issued as a dividend or distribution on account of Registrable Securities or resulting from a subdivision of the outstanding shares of Registrable Securities into a greater number of shares (by reclassification, stock split or otherwise). For the purposes of this Agreement, a security that was at one time a Registrable Security shall cease to be a Registrable Security when (a) such security has been effectively registered under the Securities Act, other than pursuant to Section 4 of this Agreement, and either (i) the registration statement with respect thereto has remained continuously effective for 150 days or (ii) such security has been disposed of pursuant to such registration statement, (b) such security is sold to the public in reliance on Rule 144 (or any similar provision then in force) under the Securities Act, (c) such security has been otherwise transferred, and (i) the Company has delivered a new certificate or other evidence of ownership not bearing the legend set forth on the Shares upon the initial issuance thereof (or other legend of similar import) and (ii) in the opinion of counsel to the Company reasonably acceptable to the Holders and addressed to the Company and the holder of such security, the subsequent disposition of such security shall not require the registration or qualification under the Securities Act, or (d) such security has ceased to be outstanding.

        Notwithstanding anything to the contrary herein, any Holder may exercise any of its rights hereunder prior to its receipt of Shares, provided that such Holder, simultaneously with the delivery of any notice requesting registration hereunder, shall deliver an Exercise Notice to the Company requesting (i) exchange, or repurchase, of Units exchangeable into, or with a repurchase price equal to, such number of Shares as such Holder has requested to be registered or (ii) conversion of 7% Preferred Shares into such number of Common Shares as such Holder has requested to be registered. Any such Exercise Notice so delivered shall be (a) conditioned on the effectiveness of the requested registration in connection with which it was delivered and (b) deemed to cover only such number of Units or Preferred Shares as are exchangeable or convertible into the number of Shares actually sold pursuant to the requested registration. Any Shares to be issued in connection with any such Exercise Notice shall be issued upon the closing of the sale of such Shares pursuant to the requested registration. In the event that the Company elects to issue all cash in lieu of Shares upon the exchange of Units covered by any such Exercise Notice, the registration requested by the Holder that delivered such Exercise Notice, if a Demand Registration, shall not constitute a Demand Registration under Section 2.1 hereof.

        Nothing contained herein shall create any obligation on the part of the Company to issue Shares, rather than cash, upon the exchange of any Units.

        2.    Demand Registration.

        3.    Piggyback Registration.    Whenever the Company proposes to file a registration statement under the Securities Act with respect to an underwritten public offering of Common Stock by the Company for its own account or for the account of any stockholders of the Company (other than a registration statement filed pursuant to either Section 2 or 4 hereof), the Company shall give written notice (the "Offering Notice") of such proposed filing to each of the Holders at least 30 days before the anticipated filing date. Such Offering Notice shall offer all such Holders the opportunity to register such number of Registrable Securities as each such Holder may request in writing, which request for registration (each, a "Piggyback Registration") must be received by the Company within 15 days after the Offering Notice is given. The Company shall use all reasonable efforts to cause the managing underwriter or underwriters of a proposed underwritten offering, if any, to permit the holders of the Registrable Securities requested to be included in the registration for such offering to include such Registrable Securities in such offering on the same terms and conditions as the common stock of the Company or, if such offering is for the account of other stockholders, the common stock of such stockholders included therein. Notwithstanding the foregoing, if the managing underwriter or underwriters of a proposed underwritten offering advise the Company in writing that in its or their opinion the number of Registrable Securities proposed to be sold in such offering exceeds the number of Registrable Securities that can be sold in such offering without adversely affecting the market for the Common Stock, the Company will include in such registration the number of Registrable Securities that in the opinion of such managing underwriter or underwriters can be sold without adversely affecting the market for the Common Stock. In such event, the number of Registrable Securities, if any, to be offered for the accounts of Holders shall be reduced pro rata on the basis of the relative number of any Registrable Securities requested by each such Holder to be included in such registration to the extent necessary to reduce the total number of Registrable Securities to be included in such offering to the number recommended by such managing underwriter or underwriters. The number of securities to be offered for the accounts of the Holders shall be reduced to zero before the number of securities to be offered for the accounts of the Priority Holders is reduced. The Company shall pay all Registration Expenses incurred in connection with any Piggyback Registration.

        4.    Shelf Registration.    Following the Effective Time, the Company shall use reasonable efforts to qualify for registration on Form S-3 for secondary sales. The Company agrees that, upon the request of any Holder, the Company shall promptly after receipt of such request notify each other Holder of receipt of such request and shall cause to be filed on or as soon as practicable thereafter, but not sooner than 35 days after the receipt of such notice from such Holder, a registration statement (a "Shelf Registration Statement") on Form S-1, Form S-3 or any other appropriate form under the Securities Act for an offering to be made on a delayed or continuous basis pursuant to Rule 415 thereunder or any similar rule that may be adopted by the Securities and Exchange Commission (the

4


"Commission") and permitting sales in any manner not involving an underwritten public offering (and shall register or qualify the shares to be sold in such offering under such other securities or "blue sky" laws as would be required pursuant to Section 7(g) hereof) covering up to the aggregate number of (a) Shares to be issued to such Holder and all other Holders who request that the Shares to be issued to them upon the exchange or repurchase of Units held by them be included in the Shelf Registration Statement upon the exchange or repurchase of Units so that the Shares issuable upon the exchange or repurchase of such Units will be registered pursuant to the Securities Act, (b) Common Shares to be issued to such Holder and all other Holders who request that the Common Shares to be issued to them upon the conversion of 7% Preferred Shares held by them be included in the Shelf Registration Statement upon the conversion of 7% Preferred Shares so that the Common Shares issuable upon the conversion of such 7% Preferred Shares will be registered for sale by such Holders pursuant to the Securities Act and (c) Registrable Securities held by such Holders. The Company shall use its best efforts to cause the Shelf Registration Statement to be declared effective by the Commission within three months after the filing thereof. The Company shall use its reasonable efforts to keep the Shelf Registration Statement continuously effective (and to register or qualify the shares to be sold in such offering under such other securities or "blue sky" laws as would be required pursuant to Section 7(g) hereof) for so long as any Holder holds any Shares or Units that may be exchanged for Shares under the Partnership Agreement or until the Company has caused to be delivered to each Holder an opinion of counsel, which counsel must be reasonably acceptable to such Holders, stating that such Shares or Shares issued upon such exchange or conversion may be sold by the Holders pursuant to Rule 144 promulgated under the Securities Act without regard to any volume limitations and that the Company has satisfied the informational requirements of Rule 144. The Company shall file any necessary listing applications or amendments to existing applications to cause the Common Shares issuable upon exchange or repurchase of Units or upon conversion of 7% Preferred Shares to be listed on the primary exchange on which the Common Stock is then listed, if any. Notwithstanding the foregoing, if the Company determines that it is necessary to amend or supplement such Shelf Registration Statement and if the Company shall furnish to the Holders a certificate signed by the Chief Executive Officer of the Company stating that in the good faith judgment of the Board of Directors of the Company it would be significantly disadvantageous to the Company and its stockholders for any such Shelf Registration Statement to be amended or supplemented, the Company may defer such amending or supplementing of such Shelf Registration Statement for not more than 45 days and in such event the Holders shall be required to discontinue disposition of any Registrable Securities covered by such Shelf Registration Statement during such period. Notwithstanding the foregoing, if the Company irrevocably elects prior to the filing of any Shelf Registration Statement to issue all cash in lieu of Shares upon the exchange of Units by the Holder requesting the filing of such Shelf Registration Statement, the Company shall not be obligated to file such Shelf Registration Statement.

        5.    Rights of Other Stockholders.    Except for the rights granted previously to the Priority Holders pursuant to the Registration Rights Agreement referred to in the first recital to this Agreement, the Company shall not grant any person (a "Subsequent Holder"), for so long as any securities convertible into or exchangeable for Registrable Securities are outstanding, any rights to have their securities included in any registration statement to be filed by the Company if such rights are greater than the rights of the Holders granted herein without extending such greater rights to the Holders. To the extent the securities of a Subsequent Holder are entitled to be included in any registration statement and the managing underwriter or underwriters believe that the number of securities proposed to be sold in such offering exceeds the number of securities that can be sold in such offering without adversely affecting the market for the Company's common stock, the number of securities to be offered for the accounts of such Subsequent Holders shall be reduced to zero before the number of securities to be offered for the accounts of the Holders is reduced. Notwithstanding the foregoing, it is understood that in any case in which the securities to be offered for the accounts of the Holders is reduced, such securities will be reduced pro rata with any securities offered for the accounts of holders of registration rights granted

5


pursuant to that certain Registration Rights Agreement among the Company and [JP Morgan, et. al] to be entered into in connection with the issuance of the Units to the Holders.

        6.    Holdback Agreements.    

6

        7.    Registration Procedures.    Whenever the Holders have requested that any Registrable Securities be registered pursuant to Section 2, 3 or 4, the Company shall use its best efforts to effect the registration of Registrable Securities in accordance with the intended method of disposition thereof as expeditiously as practicable, and in connection with any such request, the Company shall as expeditiously as possible:

        (a)   in connection with a request pursuant to Section 2, prepare and file with the Commission, not later than 40 days (or such longer period as may be required in order for the Company to comply with the provisions of Regulation S-X under the Securities Act) after receipt of a request to file a registration statement with respect to Registrable Securities, a registration statement on any form for which the Company then qualifies or which counsel for the Company shall deem appropriate and which form shall be available for the sale of such Registrable Securities in accordance with the intended method of distribution thereof and, if the offering is an underwritten offering, shall be reasonably satisfactory to the managing underwriter or underwriters, and use its best efforts to cause such registration statement to become effective; provided, however, that if the Company shall within five (5) Business Days after receipt of such request furnish to the Holders making such a request a certificate signed by the Chief Executive Officer of the Company stating that in the good faith judgment of the Board of Directors of the Company it would be significantly disadvantageous to the Company and its stockholders for such a registration statement to be filed on or before the date filing would be required, the Company shall have an additional period of not more than 45 days within which to file such registration statement (provided that only one such notice may be given during any 12 month period); and provided, further, that before filing a registration statement or prospectus or any amendments or supplements thereto, the Company shall (a) furnish to the counsel selected by the Holder making the demand, or if no demand, then, by the Holders, in the aggregate, that own or will own a majority of the Registrable Securities covered by such registration statement, copies of all such documents proposed to be filed, which documents will be subject to the review of such counsel, and (b) notify each seller or prospective seller of Registrable Securities of any stop order issued or threatened by the Commission or withdrawal of any state qualification and take all reasonable actions required to prevent such withdrawal or the entry of such stop order or to remove it if entered;

        (b)   in connection with a registration pursuant to Section 2, prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for a period of not less than 150 days (or such shorter period that will terminate when all Registrable Securities covered by such registration statement have been sold, but not before the expiration of the applicable period referred to in Section 4(3) of the Securities Act and Rule 174 thereunder, if applicable), and comply with the provisions of the Securities Act applicable to it with respect to the disposition of all securities covered by such registration statement during such period in accordance with the intended method of disposition by the sellers thereof set forth in such registration statement;

        (c)   notify each seller of Registrable Securities and the managing underwriter, if any, promptly, and (if requested by any such Person) confirm such advice in writing,

7

        (d)   use its best efforts to prevent the issuance of any stop order suspending the effectiveness of the registration statement or any state qualification or any order preventing or suspending the use of any preliminary prospectus, and use its best efforts to obtain the withdrawal of any order suspending the effectiveness of the registration statement or any state qualification or of any order preventing or suspending the use of any preliminary prospectus at the earliest possible moment;

        (e)   if requested by the managing underwriter or a seller of Registrable Securities, promptly incorporate in a prospectus supplement or post-effective amendment to the registration statement such information as the managing underwriter or a seller of Registrable Securities reasonably request to have included therein relating to the plan of distribution with respect to the Registrable Securities, including, without limitation, information with respect to the amount of Registrable Securities being sold to such underwriters, the purchase price being paid therefor by such underwriters and with respect to any other terms of the underwritten offering of the Registrable Securities to be sold in such offering; and make all required filings of such prospectus supplement or post-effective amendment promptly after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment;

        (f)    furnish to each seller of Registrable Securities and the managing underwriter one signed copy of the registration statement and each amendment thereto as filed with the Commission, and such number of copies of such registration statement, each amendment (including post-effective amendments) and supplement thereto (in each case including all documents incorporated by reference and all exhibits thereto whether or not incorporated by reference), the prospectus included in such registration statement (including each preliminary prospectus) and such other documents as each seller may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller;

        (g)   use reasonable efforts to register or qualify such Registrable Securities under such other securities or "blue sky" laws of such jurisdictions as any seller or underwriter reasonably requests in writing and to do any and all other acts and things that may be reasonably necessary or advisable to register or qualify for sale in such jurisdictions the Registrable Securities owned by such seller; provided, however, that the Company shall not be required to (a) qualify generally to do business in any jurisdiction where it is not then so qualified, (b) subject itself to taxation in any such jurisdiction, (c) consent to general service of process in any such jurisdiction or (d) provide any undertaking required by such other securities or "blue sky" laws or make any change in its charter or bylaws that the Board of Directors determines in good faith to be contrary to the best interest of the Company and its stockholders;

        (h)   use reasonable efforts to cause the Registrable Securities covered by such registration statement to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company to enable the seller or sellers thereof or the underwriters, if any, to consummate the disposition of such Registrable Securities;

        (i)    notify each seller of such Registrable Securities at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement contains an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements

8


therein, in light of the circumstances under which they were made, not misleading, and prepare and file with the Commission a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;

        (j)    enter into customary agreements (including an underwriting agreement in customary form, if the offering is an underwritten offering) and take such other actions as are reasonably required in order to expedite or facilitate the disposition of such Registrable Securities and in such connection:

        The above shall be done at the effectiveness of such registration statement (when consistent with customary industry practice), each closing under any underwriting or similar agreement as and to the extent required thereunder and from time to time as may reasonably be requested by the sellers of Registrable Securities, all in a manner consistent with customary industry practice.

        (k)   make available for inspection by any seller of Registrable Securities, any underwriter participating in any disposition pursuant to such registration statement, the counsel referred to in clause (a) of Section 7(a) and any attorney, accountant or other agent retained by any such seller or underwriter (collectively, the "Inspectors"), all financial and other records, pertinent corporate documents and properties of the Company (collectively, the "Records") as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the Company's officers, directors, employees and agents to supply all information reasonably requested by any such Inspector in connection with such registration statement. Records that the Company determines, in good faith, to be confidential and that it notifies the Inspectors are confidential shall not be disclosed by the Inspectors unless (a) the disclosure of such Records is, in the reasonable judgment of any Inspector, necessary to avoid or correct a misstatement or omission of a material fact in the registration statement or (b) the release of such Records is ordered pursuant to a subpoena or other order from a court or governmental agency of competent jurisdiction or required (in the written opinion of counsel to such

9


seller or underwriter, which counsel shall be reasonably acceptable to the Company) pursuant to applicable state or federal law. Each seller of Registrable Securities agrees that it will, upon learning that disclosure of such Records are sought by a court or governmental agency, give notice to the Company and allow the Company, at the Company's expense, to undertake appropriate action to prevent disclosure of the Records deemed confidential;

        (l)    if such sale is pursuant to an under-written offering, use reasonable efforts to obtain a "cold comfort" letter and updates thereof from the Company's independent public accountants in customary form and covering such matters of the type customarily covered by "cold comfort" letters as the holders, in the aggregate, of a majority of the Registrable Securities being sold and the managing underwriter or underwriters reasonably request;

        (m)  otherwise use reasonable efforts to comply with the Securities Act, the Exchange Act, all applicable rules and regulations of the Commission and all applicable state securities and real estate syndication laws, and make generally available to its security holders, as soon as reasonably practicable, an earnings statement covering a period of 12 months, beginning within three months after the effective date of the registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act;

        (n)   use reasonable efforts to cause all Registrable Securities covered by the registration statement to be listed on each securities exchange, if any, on which similar securities issued by the Company are then listed, provided that the applicable listing requirements are satisfied;

        (o)   cooperate with the sellers of Registrable Securities and the managing underwriter to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold and not bearing any restrictive legends; and enable such Registrable Securities to be in such denominations and registered in such names as the managing underwriter may reasonably request at least 2 business days prior to any sale of Registrable Securities to the underwriters;

        (p)   cooperate and assist in any filings required to be made with the NASD and in the performance of any due diligence investigation by any underwriter;

        (q)   prior to the filing of any document which is to be incorporated by reference into the registration statement or the prospectus (after the initial filing of the registration statement) provide copies of such document to the sellers of Registrable Securities, the underwriters and their respective counsel and make the Company representatives available for discussion of such document with such persons; and

        (r)   participate, if so requested, in a "road show" in connection with the sale of the Registrable Securities but only to the extent reasonably requested by the managing underwriter, if such sale is pursuant to an underwritten offering.

        The Company may require each seller or prospective seller of Registrable Securities as to which any registration is being effected to furnish to the Company such information regarding the distribution of such securities and other matters as may be required to be included in the registration statement.

        Each holder of Registrable Securities agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Paragraph (i) of this Section 7, such holder shall forthwith discontinue disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until such holder's receipt of the copies of the supplemented or amended prospectus contemplated by Paragraph (i) of this Section 7, and, if so directed by the Company, such holder shall deliver to the Company (at the Company's expense) all copies, other than permanent file copies then in such holder's possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. If the Company shall give any such notice, the Company shall extend the period during which such registration statement shall be maintained effective

10

pursuant to this Agreement (including the period referred to in Paragraph (b) of this Section 7) by the number of days during the period from and including the date of the giving of such notice pursuant to Paragraph (i) of this Section 7 to and including the date when each seller of Registrable Securities covered by such registration statement shall have received the copies of the supplemented or amended prospectus contemplated by Paragraph (i) of this Section 7.

        The Company shall keep the sellers of Registrable Securities to be offered in a given registration advised of the status of any registration in which they are participating. In addition, the Company and each such seller of Registrable Securities may enter into understandings in writing whereby such seller of Registrable Securities will agree in advance as to the acceptability of the price or range of prices per share at which the Registrable Securities included in such registration are to be offered to the public. Furthermore, the Company shall establish pricing notification procedures reasonably acceptable to each such seller of Registrable Securities and shall, as promptly as practicable after learning the same from the managing underwriter, use reasonable efforts to give oral notice to each such seller of Registrable Securities of the anticipated date on which the Company expects to receive a notification from the managing underwriter (and any changes in such anticipated date) of the price per share at which the Registrable Securities included in such registration are to be offered to the public.

        8.    Registration Expenses.    The Company shall pay all expenses incident to its performance of or compliance with this Agreement, including, without limitation, (a) all Commission, stock exchange and National Association of Securities Dealers, Inc. registration, filing and listing fees, (b) all fees and expenses incurred in complying with securities or "blue sky" laws (including reasonable fees and disbursements of counsel in connection with "blue sky" qualifications of the Registrable Securities), (c) all printing, messenger and delivery expenses, (d) all fees and disbursements of the Company's independent public accountants and counsel and (e) all fees and expenses of any special experts retained by the Company in connection with any Demand Registration or Piggyback Registration pursuant to the terms of this Agreement, regardless of whether such registration becomes effective; provided, however, that the Company shall not pay the costs and expenses of any Holder relating to underwriters' commissions and discounts relating to Registrable Securities to be sold by such Holder (but such costs and expenses shall be paid by the Holders on a pro rata basis), brokerage fees, transfer taxes, or the fees or expenses of any counsel, accountants or other representatives retained by the Holders, individually or in the aggregate. All of the expenses described in this Section 8 that are to be paid by the Company are herein called "Registration Expenses."

        9.    Indemnification; Contribution.    

11

12

        The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 9.4 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person.

        If indemnification is available under this Section 9, the indemnifying parties shall indemnify each indemnified party to the full extent provided in Section 9.1 and 9.2 without regard to the relative fault of said indemnifying parties or indemnified party.

        10.    Participation in Underwritten Registrations.    No person may participate in any underwritten registration hereunder unless such person (i) agrees to sell such person's securities on the basis provided in any underwriting agreements approved by the persons entitled hereunder to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.

13


        11.    Rule 144.    The Company covenants that it shall use its best efforts to file the reports required to be filed by it under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder if and when the Company becomes obligated to file such reports (or, if the Company ceases to be required to file such reports, it shall, upon the request of any Holder, make publicly available other information), and it shall, if feasible, take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (i) Rule 144 under the Securities Act, as such Rule may be amended from time to time or (ii) any similar rules or regulations hereafter adopted by the Commission. Upon the written request of any Holder, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements.

        12.    Miscellaneous.    

14

        Any party may by notice given in accordance with this Section 12.3 to the other parties designate another address or person for receipt of notice hereunder.
