SIMON PROPERTY GROUP, L.P.

Condensed Notes to Unaudited Consolidated Financial Statements

(Dollars in thousands, except unit and per unit amounts and where indicated as in millions or billions)

1.     Organization

            Simon Property Group, L.P. (the "Operating Partnership"), a Delaware limited partnership, is a majority owned subsidiary of Simon Property Group, Inc. ("Simon Property"), a Delaware corporation. Simon Property is a self-administered and self-managed real estate investment trust ("REIT") under the Internal Revenue Code of 1986, as amended (the "Code"). In these notes, the terms "we", "us" and "our" refer to the Operating Partnership and its subsidiaries.

            We are engaged primarily in the ownership, operation, leasing, management, acquisition, expansion and development of real estate properties. Our real estate properties consist primarily of regional malls and community shopping centers. As of March 31, 2003, we owned or held an interest in 241 income-producing properties in the United States, which consisted of 169 regional malls, 67 community shopping centers, and five office and mixed-use properties in 36 states (collectively, the "Properties", and individually, a "Property"). Mixed-use properties are properties whose operating income includes two or more significant retail, office, and/or hotel components. We also own interests in four parcels of land held for future development (together with the Properties, the "Portfolio"). In addition, we have ownership interests in other real estate assets and ownership interests in nine retail real estate properties operating in Europe and Canada.

            Our subsidiary, M.S. Management Associates, Inc. (the "Management Company") provides leasing, management, and development services as well as project management accounting, legal, marketing, and management information system services to most of the Properties. In addition, insurance subsidiaries of the Management Company reinsure the self-insured retention portion of our general liability and workers' compensation programs. Third party providers provide coverage above the insurance subsidiaries' limits.

            On January 1, 2003, we acquired all of the remaining equity interests of the Management Company from three Simon family members for a total purchase price of $425, which was equal to the appraised value of the interests as determined by an independent third party. The acquisition was approved by the independent directors of Simon Property. As a result, the Management Company is now our wholly owned consolidated taxable REIT subsidiary ("TRS").

2.     Basis of Presentation

            The accompanying financial statements are unaudited; however, we prepared the accompanying financial statements in accordance with accounting principles generally accepted in the United States for interim financial information and in conjunction with the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the disclosures required by accounting principles generally accepted in the United States for complete financial statements.

            The accompanying unaudited financial statements of the Operating Partnership include the Operating Partnership and its subsidiaries. In our opinion, all adjustments necessary for fair presentation, consisting of only normal recurring adjustments, have been included. We eliminated all significant intercompany amounts. The results for the interim period ended March 31, 2003 are not necessarily indicative of the results to be obtained for the full fiscal year. We prepared these unaudited financial statements in accordance with the accounting policies described in our annual report on Form 10-K for the year ended December 31, 2002.

            As of March 31, 2003, of our 241 Properties we consolidated 159 wholly-owned Properties and 14 less than wholly owned Properties which we control, and we accounted for 68 Properties using the equity method. We manage the day-to-day operations of 59 of the 68 equity method Properties.

6



            We allocate our net operating results after preferred distributions based on our general partner's, Simon Property's, and the limited partners' respective ownership interests. Simon Property's weighted average direct and indirect ownership interest in us was as follows:

 
For the three months ended March 31,
 
 
2003
  2002
 
  74.8 % 72.9 %

            Simon Property's direct and indirect ownership interest in us at March 31, 2003 was 75.5% and at December 31, 2002 was 74.3%.

            Preferred distributions in the accompanying statements of operations and cash flows represent distributions on outstanding preferred units. We made certain reclassifications of prior period amounts in the financial statements to conform to the 2003 presentation. As a result of the consolidation of the Management Company, we have elected to present "management fees and other revenues" as a separate revenue caption. In addition, we have elected to present "Home and regional office costs" and "General and administrative expenses" as separate expense captions. In 2002, "Home and regional office costs" and "General and administrative expense" incurred related to consolidated Properties was included in "Property operating expense". Effective with the consolidation of the Management Company, these expenses included in "Property operating expenses" through March 31, 2002 have been reclassified to conform with the current year presentation. "Home and regional office costs" include salary and benefits, office rent, office expenses and information services expenses incurred in our home office and regional offices. "General and administrative expense" represents the costs of operating as a public company and includes such items as stock exchange fees, public and investor relations expenses, certain executive officers' compensation expenses, audit fees, and legal fees.

3.     Per Unit Data

            We determine basic earnings per unit of partnership interest ("Unit" or "Units") on the weighted average number of Units outstanding during the period. We determine diluted earnings per Unit on the weighted average number of Units outstanding combined with the incremental weighted average Units that would have been outstanding assuming all dilutive potential Units were converted into Units at the earliest date possible. The following table sets forth the weighted average Units used in the computation of our basic and diluted earnings per Unit.

 
  For the Three Months Ended March 31,
 
  2003
  2002
Weighted Average Units — Basic   247,812,060   236,167,366
Effect of stock options   674,369   582,718
   
 
Weighted Average Units — Diluted   248,486,429   236,750,084
   
 

            Our potentially dilutive securities include the Series B convertible preferred units and certain other classes of preferred units, none of which had a dilutive effect in any period presented. Units held by the limited partners may be exchanged for shares of common stock in Simon Property, on a one-for-one basis in certain circumstances. If exchanged, the Units would not have a dilutive effect. We accrue distributions when they are declared.

4.     Cash Flow Information

            Our balance of cash and cash equivalents as of March 31, 2003 included $74.9 million and as of December 31, 2002 included $171.2 million related to our gift certificate program, which we do not consider available for general working capital purposes.

5.     Investment in Unconsolidated Entities

Real Estate Joint Ventures

            Joint ventures are common in the real estate industry. We use joint ventures to finance certain properties and to diversify our risk in a particular asset or trade area. We may also use joint ventures in the development of new

7



properties. We held joint venture ownership interests in 68 Properties as of March 31, 2003 and as of December 31, 2002. As discussed in Note 2, since we do not fully control these joint venture Properties, accounting principles generally accepted in the United States require that we account for these Properties on the equity method. Substantially all of our joint venture Properties are subject to rights of first refusal, buy-sell provisions, or other sale rights for all partners which are customary in real estate partnership agreements and the industry. Our partners in these joint ventures may initiate these provisions at any time, which will result in either the use of available cash or borrowings to acquire or dispose of the partnership interest.

            Summary financial information of the joint ventures and a summary of our investment in and share of income from such joint ventures follow. We condensed into separate line items major captions of the statements of operations for joint venture interests sold or consolidated, when we have acquired an additional interest in a joint venture and have as a result, gained control of the Property. These line items include "Discontinued Joint Venture Interests" to present comparative results of operations for those joint venture interests held as of March 31, 2003.

            "Excess Investment" represents the unamortized difference of our investment over our share of the equity in the underlying net asset of the joint ventures acquired. We amortize excess investment over the life of the related Properties, typically 35 years, and the amortization is included in income from unconsolidated entities.

Management Company

            As previously mentioned, we consolidated the Management Company effective January 1, 2003. Therefore, the unaudited balance sheet as of March 31, 2003 and the unaudited statements of operations and comprehensive income, and statements of cash flows for the period ended March 31, 2003 include the balance sheet and results of operations of the Management Company. Revenues of the Management Company, after intercompany eliminations, consist primarily of management fee revenues earned and are typically based upon the revenues of the property being managed. Substantially all of these revenues are derived from the management of unconsolidated joint venture Properties. We consolidated the Management Company as of January 1, 2003 at historical book values because the transaction occurred with the initial sponsors of Simon Property. The assets of the Management Company of approximately $200 million, after intercompany eliminations, consist primarily of the investments of its insurance subsidiaries, investments in unconsolidated entities, a net deferred tax asset, and fixed assets. The liabilities of the Management Company of approximately $50 million, after intercompany eliminations, consist primarily of the reserves of its insurance subsidiaries and accounts payable and accrued expenses.

            Through December 31, 2002, we accounted for our interest in the Management Company under the equity method of accounting. Our net investment in the Management Company, excluded from the tables above, was $95.5 million as of December 31, 2002. Our share of the Management Company's consolidated net loss including

MerchantWired LLC's (a discontinued joint venture) net loss after intercompany profit eliminations during the three month period ended March 31, 2002 is presented below:

Our share of:

   
 
Management Company income excluding losses from
MerchantWired LLC
  $1,273  
Losses from MerchantWired LLC   (8,271 )
   
 
Total net loss   ($6,998 )
   
 

            The losses from MerchantWired LLC presented above and in the accompanying statements of operations and comprehensive income for the three months ended March 31, 2002 include our indirect share of the operating losses of MerchantWired LLC of $8.3 million, after a tax benefit of $5.1 million. The operating losses include our share of an impairment charge of $4.2 million, after tax.

6.     Debt

            On March 18, 2003, we issued two tranches of senior unsecured notes to institutional investors pursuant to Rule 144A totaling $500.0 million at a weighted average fixed interest rate of 5.11%. The first tranche is $300.0 million at a fixed interest rate of 4.875% due March 18, 2010 and the second tranche is $200.0 million at a fixed interest rate of 5.45% due March 15, 2013. The net proceeds from this offering were $498.7 million of which $440.0 million was used to reduce borrowings on our $1.25 billion unsecured credit facility (the "Credit Facility"). We agreed to use our reasonable best efforts to file and have declared effective a registration statement under the Securities Act of 1933 relating to an offer to exchange the notes of each series for registered notes with substantially identical economic terms. If we do not complete the exchange offer within 180 days after the issuance of the notes, the interest rates on the notes will be increased by 0.50% per year.

            On April 1, 2003, we paid off $100.0 million of 7.05% unsecured notes that matured on that date with the remaining portion of the proceeds from the senior unsecured notes mentioned above and available working capital.

7.     Partners' Equity

            On January 22, 2003, three limited partners exchanged 13,469 Units with Simon Property for 13,469 shares of Simon Property common stock. On February 19, 2003, two limited partners exchanged 2,867,342 Units with Simon Property for 2,867,342 shares of Simon Property common stock.

            On February 13, 2003, we issued 364,405 Units to Simon Property in connection with Simon Property's issuance of 364,405 shares of restricted stock that were awarded under The Simon Property Group 1998 Stock Incentive Plan at a value of $33.20 per share. The fair market value of the restricted stock awarded has been deferred and is being amortized over the four year vesting period.

            We issued 178,989 Units to Simon Property related to employee stock options exercised during the first three months of 2003. We used the net proceeds from the option exercises of approximately $4.3 million for general working capital purposes.

8.     Commitments and Contingencies

            Triple Five of Minnesota, Inc., a Minnesota corporation, v. Melvin Simon, et. al. On or about November 9, 1999, Triple Five of Minnesota, Inc. commenced an action in the District Court for the State of Minnesota, Fourth Judicial District, against, among others, Mall of America, certain members of the Simon family and entities allegedly controlled by such individuals, and us. The action was later removed to federal court. Two transactions form the basis of the complaint: (i) the sale by Teachers Insurance and Annuity Association of America of one-half of its partnership interest in Mall of America Company and Minntertainment Company to the Operating Partnership and related entities; and (ii) a financing transaction involving a loan in the amount of $312.0 million obtained from The Chase Manhattan Bank that is secured by a mortgage placed on Mall of America's assets. The complaint, which contains twelve counts, seeks remedies of unspecified damages, rescission, constructive trust, accounting, and specific performance. Although the complaint names all defendants in several counts, we are specifically identified as a defendant in connection with the sale to Teachers. Although the Complaint seeks unspecified damages, Triple Five has

10


submitted a report of a purported expert witness that attempts to quantify its damages at between approximately $80 million and $160 million. On August 12, 2002, the court granted in part and denied in part motions for partial summary judgment filed by the parties. The court has scheduled a trial date of June 2, 2003. Given that the case is still in the pre-trial stage, it is not possible to provide an assurance of the ultimate outcome of the litigation or an estimate of the amount or range of potential loss, if any. We believe that the Triple Five litigation will not have a material adverse effect on our financial position or results of operations. In connection with the financing, we agreed to indemnify the mortgage loan lenders and other nonparties to the litigation for certain costs, including litigation expenses and damages.

            We are currently not subject to any other material litigation other than routine litigation, claims and administrative proceedings arising in the ordinary course of business. We believe that such routine litigation, claims and administrative proceedings will not have a material adverse impact on our financial position or our results of operations.

            Joint venture debt is the liability of the joint venture, is typically secured by the joint venture Property, and is non-recourse to us. As of March 31, 2003, we have guaranteed or have provided letters of credit to support $66.8 million of our total $2.3 billion share of joint venture mortgage and other indebtedness in the event the joint venture partnership defaults under the terms of the mortgage. The mortgages guaranteed are secured by the property of the joint venture partnership which could be sold in order to satisfy the outstanding obligation.

            On December 5, 2002, Simon Property Acquisitions, Inc., a wholly-owned subsidiary of Simon Property, commenced a tender offer to acquire all of the outstanding shares of Taubman Centers, Inc. at a price of $18.00 per share in cash. On January 15, 2003, Westfield America, Inc., the U.S. subsidiary of Westfield America Trust, joined Simon Property's tender offer and they jointly increased the tender offer to $20.00 per share in cash. As of February 14, 2003 and March, 28, 2003, a total of 44,135,107 and 40,302,385 of the 52,207,756 common shares outstanding of Taubman Centers, Inc., were tendered into the offer, respectively. The expiration date of the tender offer has been extended to May 30, 2003. Under the terms of our partnership agreement, we pay the operating expenses of Simon Property. As a result, we have deferred $7.2 million, net, in acquisition costs related to this acquisition. If Simon Property is unsuccessful in its efforts, then these costs will be expensed.

9.     Real Estate Dispositions and Acquisitions

            On January 11, 2003, the minority limited partner in The Forum Shops at Caesars in Las Vegas, NV initiated the buy/sell provision of the partnership agreement. On March 14, 2003, we purchased this interest for $174.0 million in cash and assumed the minority limited partner's $74.2 million share of debt, and other partnership liabilities. We funded this purchase with borrowings on our Credit Facility. We recorded minority interest expense relating to the minority limited partner's share of the results of operations of The Forum Shops at Caesars through March 14, 2003.

            On January 9, 2003, we continued our disposition activities with the sale of four non-core Properties. These Properties consisted of Richmond Square, Mounds Mall, Mounds Mall Cinema, and Memorial Mall. We sold these Properties for $31.8 million and we recorded a net gain of $4.3 million.

            On April 29, 2003, we sold Forest Village Park Mall, another non-core Property, for $20.5 million which resulted in a gain.

Item 2.    Management's Discussion and Analysis of Financial Condition and Results of Operations

            You should read the following discussion in conjunction with the financial statements and notes thereto that are included in this quarterly report on Form 10-Q. Certain statements made in this section or elsewhere in this report may be deemed "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Although we believe the expectations reflected in any forward-looking statements are based on reasonable assumptions, we can give no assurance that our expectations will be attained, and it is possible that our actual results may differ materially from those indicated by these forward-looking statements due to a variety of risks and uncertainties. Those risks and uncertainties incidental to the ownership and operation of commercial real estate include, but are not limited to: national, international, regional and local economic climates, competitive market forces, changes in market rental rates, trends in the retail industry, the inability to collect rent due to the bankruptcy or insolvency of tenants or otherwise, risks associated with acquisitions, the impact of terrorist activities, environmental liabilities, maintenance of Simon Property's REIT status, the availability of financing, and changes in market rates of interest. We undertake no duty or obligation to update or revise these forward-looking statements, whether as a result of new information, future developments, or otherwise.

Overview

            Simon Property Group, L.P. (the "Operating Partnership"), a Delaware limited partnership, is a majority owned subsidiary of Simon Property Group, Inc. ("Simon Property"), a Delaware corporation. Simon Property is a self-administered and self-managed real estate investment trust ("REIT") under the Internal Revenue Code of 1986, as amended (the "Code"). In this discussion, the terms "we", "us" and "our" refer to the Operating Partnership and its subsidiaries.

            We are engaged primarily in the ownership, operation, leasing, management, acquisition, expansion and development of real estate properties. Our real estate properties consist primarily of regional malls and community shopping centers. As of March 31, 2003, we owned or held an interest in 241 income-producing properties in the United States, which consisted of 169 regional malls, 67 community shopping centers, and five office and mixed-use properties in 36 states (collectively, the "Properties", and individually, a "Property"). Mixed-use properties are properties whose operating income includes two or more significant retail, office, and/or hotel components. We also own interests in four parcels of land held for future development (together with the Properties, the "Portfolio"). In addition, we have ownership interests in other real estate assets and ownership interests in nine retail real estate properties operating in Europe and Canada.

            We generate the majority of our revenues from leases with retail tenants including:

            Revenues of the Management Company, after intercompany eliminations, consist primarily of management fees that are typically based upon the revenues of the property being managed. We also generate revenues due to our size and tenant relationships from the following:


Operational Overview

            Our core business remained strong during the first quarter of 2003. Regional mall occupancy increased 80 basis points to 91.7% as of March 31, 2003 from 90.9% as of March 31, 2002. Regional mall average base rents increased

12



6.0% to $31.24 per square foot ("psf") as of March 31, 2003 from $29.47 psf as of March 31, 2002. Our regional mall leasing spreads during the first quarter were $12.24 psf as of March 31, 2003 compared to $6.60 psf as of March 31, 2002. The regional mall leasing spread for 2003 includes new store leases signed at an average of $45.52 psf initial base rents as compared to $33.28 psf for store leases terminating or expiring in the same period. We anticipate that the leasing spreads will normalize by December 31, 2003 to be in line with historical leasing spreads. Our same store leasing spread was $8.72 or a 23.0% growth rate. This leasing spread is calculated for spaces leased during the current period based upon the difference between the opening and terminating or expiring average rents psf for spaces that have been occupied during the last 24 months. Regional mall comparable sales psf increased 1.8% to $390 psf as of March 31, 2003, from $383 as of March 31, 2002, despite the weak overall economy.

            During the first quarter of 2003, we also continued to realize the benefits of the acquisitions we made during 2002. These acquisitions added $41.0 million to our 2003 consolidated total revenues, $11.0 million to our 2003 consolidated operating income, and $4.4 million to our 2003 income from unconsolidated entities. In addition, on March 14, 2003 we purchased the remaining ownership interest in The Forum Shops at Caesars in Las Vegas, NV from the minority limited partner in this Property who initiated the buy/sell provision of the partnership agreement. We funded this purchase with borrowings on our $1.25 billion unsecured credit facility (the "Credit Facility").

            We also took advantage of the continuing low long-term interest rate environment by issuing $500.0 million of unsecured notes on March 18, 2003 at a weighted average fixed interest rate of 5.11%. In connection with this offering we entered into interest rate lock agreements. After including the impact of these hedging activities the all-in blended effective rate for this offering was 4.88%. We used the net proceeds of $498.7 million primarily to reduce borrowings on our Credit Facility.

            We expect our overall Portfolio performance will be stable in 2003 as we expect to maintain similar leasing spreads, maintain or increase occupancy, and increase average base rents psf.

            The Portfolio data as discussed in this operational overview includes some of the key operating statistics for our regional malls that we believe are necessary to understand our business. The Portfolio data includes occupancy, average base rents psf, leasing spreads, and comparable sales psf. Operating statistics give effect to newly acquired Properties beginning in the year of acquisition and do not include those Properties located outside of the United States. This operational overview is subject to the more detailed descriptions of our operations appearing elsewhere in this report.

Results of Operations

            The following acquisitions, dispositions, and openings affected our consolidated results of operations in the comparative periods:

            The following acquisitions, dispositions, and openings affected our income from unconsolidated entities in the comparative periods:

13


            The transactions noted above are collectively referred to as the "Property Transactions". In the following discussions of our results of operations "comparable" refers to Properties open and operating throughout both the current and prior three-month periods.

            In addition to the Property Transactions, on January 1, 2003, we acquired all of the remaining equity interests of the Management Company from three Simon family members. The Management Company was previously accounted for using the equity method during the three-months ended March 31, 2002. The Management Company is now consolidated, therefore, its revenues and expenses are included in the accompanying unaudited statement of operations and comprehensive income for the three-months ended March 31, 2003. On March 14, 2003, we purchased the remaining ownership interest in The Forum Shops at Caesars in Las Vegas, NV, which impacted our minority interest expense.

            Minimum rents, excluding rents from our consolidated Simon Brand Ventures ("Simon Brand") and Simon Business Network ("Simon Business") initiatives, increased $26.1 million during the period. The net effect of the Property Transactions increased these rents $18.1 million. Comparable rents increased $8.0 million due to leasing of space at higher rents and increased occupancy, resulting in an increase in base rents of $6.9 million, and an increase in temporary tenant income of $1.1 million primarily due to increased rents from kiosks. The Management Company recorded fee revenues of $13.2 million and insurance premium revenues of $5.6 million. Substantially all of the Management Company revenues are management, leasing, development fees and insurance premium revenues received from unconsolidated joint venture Properties. Total other income, excluding Simon Brand and Simon Business initiatives, decreased $9.0 million. The impact of the consolidation of the Management Company also includes the elimination of consolidated intercompany interest and dividend income of $3.3 million received from the Management Company previously recorded in other income in 2002. In addition, lease settlements decreased by $3.1 million and outlot land sales decreased by $3.7 million during the comparative period.

            Consolidated revenues from Simon Brand and Simon Business initiatives increased $4.3 million to $18.4 million from $14.1 million. This increase includes a net $2.1 million increase primarily from parking services included in the Property Transactions and a $2.2 million increase in revenues from our gift certificate and gift card programs. The increase in tenant reimbursements resulted from the Property Transactions and increased recoverable expenditures.

            Depreciation and amortization expenses increased $12.5 million primarily due to the net effect of the Property Transactions. Other expenses decreased $5.2 million resulting from our recording $5.4 million in other expense in 2002 for the fair value and transaction costs of our Euro collar hedge which we executed in connection with the Rodamco acquisition. In total, the consolidation of the Management Company added $9.5 million of total operating expenses in 2003 and which is the primary reason for the increase in home office and regional office costs and general and administrative expenses.

            Interest expense increased $3.6 million and is the result of increased average borrowings as a result of the funding of and assumption of consolidated Property level debt as part of the Rodamco acquisition. These increases were offset by an overall decrease in weighted average interest rates as a result of our refinancing activity over the past year and lower variable interest rate levels.

            On January 9, 2003, we continued our disposition activities with the sale of a portfolio of four non-core Properties for $31.8 million which resulted in a net gain of $4.3 million.

            Income from unconsolidated entities increased $3.7 million during the comparative periods. Income from unconsolidated partnerships and joint ventures increased $4.9 million resulting from the Rodamco acquisition but was offset by the loss of income due to the sale of our interests in the Mills Properties and Orlando Premium Outlets. In 2002, income from unconsolidated entities included income from the Management Company of $1.3 million. Losses from MerchantWired LLC, a discontinued joint venture, in 2002 included our indirect share of the operating losses of MerchantWired LLC of $8.3 million, after a tax benefit of $5.1 million. The operating losses of MerchantWired LLC included our share of an impairment charge of $4.2 million, after tax. The Management Company wrote off its investment in MerchantWired LLC in June 2002. The impact to net income for the results of operations of the Management Company, excluding the losses of MerchantWired LLC, in the comparative periods was an increase of approximately $4.6 million due to increased management fees, leasing fees and capitalized development costs.

Liquidity and Capital Resources

            Our liquidity is derived primarily from our leases that generate positive net cash flow from operations and distributions from unconsolidated entities. Our balance of cash and cash equivalents increased $9.7 million to $400.3 million as of March 31, 2003, including a balance of $74.9 million related to our gift certificate program, which we do not consider available for general working capital purposes.

            Another source of liquidity is our Credit Facility, which provides flexibility as our cash needs vary from time to time. On March 31, 2003, the Credit Facility had available borrowing capacity of $1.1 billion net of outstanding borrowings of $75.0 million and letters of credit of $26.2 million. The Credit Facility bears interest at LIBOR plus 65 basis points with an additional 15 basis point facility fee on the entire $1.25 billion facility and provides for variable grid pricing based upon our corporate credit rating. The Credit Facility has an initial maturity of April, 2005, with an additional one-year extension available at our option. We and Simon Property also have access to public equity and long term unsecured debt markets. Finally, we have access to private equity from institutional investors at the Property level. Our current senior unsecured debt ratings are Baa2 by Moody's Investors Service and BBB by Standard & Poor's and Simon Property's current corporate rating is BBB+ by Standard & Poor's.

            Our net cash flow from operating activities and distributions of capital from unconsolidated entities totaled $81.4 million and we consolidated $48.9 million of cash from the acquisition of the remaining ownership interests in the Management Company. In addition, we received $31.8 million in connection with the sale of four non-core Properties. Finally, we had net proceeds from all of our debt financing and repayment activities of $269.2 million which we used primarily to fund our $174.0 million acquisition of the remaining ownership interest in The Forum Shops at Caesars in Las Vegas, NV. We also:

            In general, we anticipate that cash generated from operations will be sufficient in 2003, as well as on a long-term basis, to meet operating expenses, monthly debt service, recurring capital expenditures, and distributions to unitholders necessary to maintain Simon Property's REIT qualification. In addition, we expect to be able to obtain capital for nonrecurring capital expenditures, such as acquisitions, major building renovations and expansions, as well as for scheduled principal maturities on outstanding indebtedness, from:

Financing and Debt

            Unsecured Financing.    On March 18, 2003, we issued two tranches of senior unsecured notes to institutional investors pursuant to Rule 144A totaling $500.0 million at a weighted average fixed interest rate of 5.11%. The first tranche is $300.0 million at a fixed interest rate of 4.875% due March 18, 2010 and the second tranche is $200.0 million at a fixed interest rate of 5.45% due March 15, 2013. We used the net proceeds of $498.7 million primarily to reduce borrowings on our Credit Facility. We agreed to use our reasonable best efforts to file and have declared effective a registration statement under the Securities Act of 1933 relating to an offer to exchange the notes of each series for registered notes with substantially identical economic terms. If we do not complete the exchange offer within 180 days after the issuance of the notes, the interest rates on the notes will be increased by 0.50% per year.

            Credit Facility.    During the first quarter of 2003, the maximum amount outstanding under the Credit Facility was $515.0 million and the weighted average amount outstanding was $294.8 million. The weighted average interest rate was 1.97% for the period ended March 31, 2003.

            Summary of Financing.    Our consolidated debt adjusted to reflect outstanding derivative instruments consisted of the following:

Debt Subject to

  Adjusted Balance as of March 31, 2003
  Effective Weighted Average Interest Rate
  Adjusted Balance as of December 31, 2002
  Effective Weighted Average Interest Rate
Fixed Rate   $ 8,429,161   6.71%   $ 7,941,122   6.81%
Variable Rate     1,374,738   3.71%     1,604,959   3.58%
   
 
 
 
    $ 9,803,899   6.29%   $ 9,546,081   6.27%
   
     
   

            As of March 31, 2003, we had interest rate cap protection agreements on $296.9 million of consolidated variable rate debt. We had interest rate protection agreements effectively converting variable rate debt to fixed rate debt on $162.2 million of consolidated variable rate debt. In addition, we hold $400.0 million of notional amount fixed rate swap agreements that have a weighted average pay rate of 1.55% and a weighted average receive rate of 1.35% at March 31, 2003 which mature in June and December 2003. We also hold $675.0 million of notional amount variable rate swap agreements that have a weighted average pay rate of 1.26% and a weighted average receive rate of 3.33% at March 31, 2003 which mature in June 2003 and February 2004. As of March 31, 2003, the net effect of these agreements effectively converted $112.8 million of fixed rate debt to variable rate debt. As of December 31, 2002, the net effect of these agreements effectively converted $112.7 million of fixed rate debt to variable rate debt.

            The following table summarizes the material aspects of our future obligations as of March 31, 2003:

Represents principal maturities only and therefore, excludes net premiums and discounts and fair value swaps of $21,555.

(2)
Represents our pro rata share of principal maturities and excludes net premiums and discounts.

            We expect to meet our 2003 maturities through refinancings, the issuance of new debt securities or borrowings on the Credit Facility. We expect to meet all future long term obligations. Specific financing decisions, however, will be made based upon market rates, property values, and our desired capital structure at the maturity date of each transaction. Joint venture debt is the liability of the joint venture, is typically secured by the joint venture Property, and is non-recourse to us. As of March 31, 2003, we have guaranteed or have provided letters of credit to support $66.8 million of our total $2.3 billion share of joint venture mortgage and other indebtedness presented in the table above.

            On February 5, 2003, Simon Property's Board of Directors approved an increase in our distribution rate to $2.40 per Unit. The Board of Directors declared and we paid a distribution of $0.60 per Unit in the first quarter of 2003. We are required to make distributions to maintain Simon Property's status as a REIT. Our distributions typically exceed our net income generated in any given year primarily because of depreciation, which is a "non-cash" expense. Our future distributions will be determined by the Board of Directors based on actual results of operations, cash available for distributions, and what may be required to maintain Simon Property's status as a REIT.

16


            Acquisitions.    Acquisition activity is a component of our growth strategy. We selectively acquire individual properties or portfolios of properties, focusing on quality retail real estate. We review and evaluate a limited number of acquisition opportunities as part of this strategy. The minority limited partner in The Forum Shops at Caesars in Las Vegas, NV initiated the buy/sell provision of the partnership agreement. On March 14, 2003, we purchased this interest for $174.0 million in cash and assumed the minority limited partner's $74.2 million share of debt, and other partnership liabilities. We expect this transaction to provide increased net income and cash flow in 2003 and future periods.

            Buy/sell provisions are common in real estate partnership agreements. Most of our partners are institutional investors who have a history of direct investment in regional mall properties. Partners in our joint ventures may initiate these provisions at any time and if we determine it is in our shareholders' best interests for us to purchase the joint venture interest, we believe we currently have adequate liquidity to execute the purchases of the interests without hindering our cash flows or liquidity. Should we decide to sell any of our joint venture interests, we would expect to use the net proceeds from sale to reduce outstanding indebtedness.

            On December 5, 2002, Simon Property Acquisitions, Inc., a wholly-owned subsidiary of Simon Property, commenced a tender offer to acquire all of the outstanding shares of Taubman Centers, Inc. at a price of $18.00 per share in cash. On January 15, 2003, Westfield America, Inc., the U.S. subsidiary of Westfield America Trust, joined Simon Property's tender offer and they jointly increased the tender offer to $20.00 per share in cash. As of February 14, 2003 and March, 28, 2003, a total of 44,135,107 and 40,302,385 of the 52,207,756 common shares outstanding of Taubman Centers, Inc., were tendered into the offer, respectively. The expiration date of the tender offer has been extended to May 30, 2003. Under the terms of our partnership agreement, we pay the operating expenses of Simon Property. As a result, we have deferred $7.2 million, net, in acquisition costs related to this acquisition. If Simon Property is unsuccessful in its efforts, then these costs will be expensed.

            Dispositions.    We continue to pursue the sale, under the right circumstances, of Properties that no longer meet our strategic criteria. If we sell any Properties that are classified as held for use, their sale prices may differ from their carrying value. We do not believe the sale of these assets will have a material impact on our future results of operations or cash flows and their removal from service and sale will not materially affect our ongoing operations.

            We pursue new development as well as strategic expansion and renovation activity when we believe the investment of our capital meets our risk-reward criteria.

            New Developments.    Development activities are an ongoing part of our business and we seek to selectively develop new properties in major metropolitan areas that exhibit strong population and economic growth. The following describes our current new development projects and the estimated total cost, our share of the estimated total cost and the construction in progress balance as of March 31, 2003 (dollars in millions):

Property

  Location
  Gross Leasable Area
  Estimated Total Cost
  Our Share of Estimated Total Cost
  Our Share of Construction in Progress
  Estimated Opening Date
Chicago Premium Outlets   Chicago, IL   438,000   $ 79.0   $ 39.5   $ 10.5   2nd Quarter 2004
Las Vegas Premium Outlets   Las Vegas, NV   435,000     88.0     44.0     29.4   August 2003
Rockaway Town Court   Rockaway, NJ   89,000     17.0     17.0     6.3   September 2003
Lakeline Village   Austin, TX   42,000     5.0     5.0     3.3   October 2003

            We expect to fund these non-recurring capital projects with either available cash flow from operations or borrowings on our Credit Facility. We invested approximately $13.7 million in these four development projects during the first quarter of 2003. In total, our share of new developments in 2003 on an accrual basis was approximately $22.7 million. We expect 2003 new development costs during the year to be approximately $64.5 million.

            Strategic Expansions and Renovations.    We also seek to increase the profitability and market share of the Properties through strategic renovations and expansions. We invested approximately $37.9 million on an accrual basis in redevelopment projects during the first quarter of 2003. We have renovation and/or expansion projects currently under construction, or in preconstruction development and expect to invest a total of approximately $144.3 million on redevelopment projects in 2003. The following describes our significant renovation and/or expansion projects currently

(a)
Amounts include the portion of the project placed in service as of March 31, 2003, if any. As of March 31, 2003, our share of construction in progress for the project at The Galleria was $0.1 million and at Dadeland Mall was $2.5 million.

            International.    We have a 35.2% ownership interest in European Retail Enterprises, B.V. ("ERE"), that is accounted for using the equity method of accounting. ERE also operates through a wholly-owned subsidiary Groupe BEG, S.A. ("BEG"). ERE and BEG are fully integrated European retail real estate developers, lessors and managers. Our total current investment in ERE and BEG, including subordinated debt, is approximately $80.3 million. The agreements with BEG and ERE are structured to allow us to acquire an additional 26.1% ownership interest over time. The future commitments to purchase shares from three of the existing shareholders of ERE are based upon a multiple of adjusted results of operations in the year prior to the purchase of the shares. Therefore, the actual amount of these additional commitments may vary. The current estimated additional commitment is approximately $50 million to purchase shares of stock of ERE, assuming that the three existing shareholders exercise their rights under put options. We expect these purchases to be made from 2004-2008. As of March 31, 2003, ERE and BEG had five Properties open in Poland and three in France.

Retail Climate and Tenant Bankruptcies

            Bankruptcy filings by retailers are normal in the course of our operations. We are continually releasing vacant spaces resulting from tenant terminations. Pressures which affect consumer confidence, job growth, energy costs and income gains can affect retail sales growth, and a continuing soft economic cycle may impact our ability to retenant property vacancies resulting from store closings or bankruptcies. We lost 400,000 of square feet of mall shop tenants in 2002. We expect 2003 to be slightly higher than 2002 in terms of square feet lost to bankruptcies, however, we cannot assure you that this will occur.

            The geographical diversity of our Portfolio mitigates some of the risk of an economic downturn. In addition, the diversity of our tenant mix also is important because no single retailer represents either more than 2.4% of total GLA or more than 5.3% of our annualized base minimum rent. Bankruptcies and store closings may, in some circumstances, create opportunities for us to release spaces at higher rents to tenants with enhanced sales performance. We have demonstrated an ability to successfully retenant anchor and in line store locations during soft economic cycles. While these factors reflect some of the inherent strengths of our portfolio in a difficult retail environment, we cannot assure you that we will successfully execute our releasing strategy.

Seasonality

            The shopping center industry is seasonal in nature, particularly in the fourth quarter during the holiday season, when tenant occupancy and retail sales are typically at their highest levels. In addition, shopping malls achieve most of their temporary tenant rents during the holiday season. As a result, our earnings are generally highest in the fourth quarter of each year.

            In addition, given the number of Properties in warm summer climates our utility expenses are typically higher in the months of June through September due to higher electricity costs to supply air conditioning to our Properties. As a result some seasonality results in increased property operating expenses during these months; however, the majority of these costs are recoverable from tenants.

Environmental Matters

            Nearly all of the Properties have been subjected to Phase I or similar environmental audits. Such audits have not revealed nor is management aware of any environmental liability that we believe would have a material adverse

18



impact on our financial position or results of operations. We are unaware of any instances in which we would incur significant environmental costs if any or all Properties were sold, disposed of or abandoned.


Item 3.    Qualitative and Quantitative Disclosure About Market Risk

            Sensitivity Analysis.    A comprehensive qualitative and quantitative analysis regarding market risk is disclosed in our Form 10-K for the year ended December 31, 2002. There have been no material changes in the assumptions used or results obtained regarding market risk since December 31, 2002.

Part II — Other Information

            Triple Five of Minnesota, Inc., a Minnesota corporation, v. Melvin Simon, et. al. On or about November 9, 1999, Triple Five of Minnesota, Inc. commenced an action in the District Court for the State of Minnesota, Fourth Judicial District, against, among others, Mall of America, certain members of the Simon family and entities allegedly controlled by such individuals, and us. The action was later removed to federal court. Two transactions form the basis of the complaint: (i) the sale by Teachers Insurance and Annuity Association of America of one-half of its partnership interest in Mall of America Company and Minntertainment Company to the Operating Partnership and related entities; and (ii) a financing transaction involving a loan in the amount of $312.0 million obtained from The Chase Manhattan Bank that is secured by a mortgage placed on Mall of America's assets. The complaint, which contains twelve counts, seeks remedies of unspecified damages, rescission, constructive trust, accounting, and specific performance. Although the complaint names all defendants in several counts, we are specifically identified as a defendant in connection with the sale to Teachers. Although the Complaint seeks unspecified damages, Triple Five has submitted a report of a purported expert witness that attempts to quantify its damages at between approximately $80 million and $160 million. On August 12, 2002, the court granted in part and denied in part motions for partial summary judgment filed by the parties. The court has scheduled a trial date of June 2, 2003. Given that the case is still in the pre-trial stage, it is not possible to provide an assurance of the ultimate outcome of the litigation or an estimate of the amount or range of potential loss, if any. We believe that the Triple Five litigation will not have a material adverse effect on our financial position or results of operations. In connection with the financing, we agreed to indemnify the mortgage loan lenders and other nonparties to the litigation for certain costs, including litigation expenses and damages.

            Taubman Centers, Inc.    On December 5, 2002, Simon Property commenced litigation in the United States District Court for the Eastern District of Michigan (the "Court") against Taubman Centers, its Board of Directors and certain members of the Taubman family. In that action, Simon Property broadly alleges that the Board of Directors has breached, and continues to breach, its fiduciary duties by failing to consider Simon Property's offer on the merits, and that the Taubman family should be prevented from voting its Series B Preferred Stock which Simon Property contends was wrongfully obtained by the Taubman family without a shareholder vote and in violation of Michigan law. Simon Property filed a first amended complaint and a second amended complaint on December 30, 2002 and February 5, 2003, respectively. The initial complaint and each amended complaint has been filed with the Commission as an exhibit to Simon Property's Tender Offer Statement on Schedule TO. On January 22, 2003, the Court issued an opinion and order denying in part, and granting in part, Taubman Centers' and the other defendants' motion to dismiss Count I of Simon Property's complaint, as amended. The Court held that while the issuance in 1998 of the Series B Preferred Stock by Taubman Centers to the Taubman family did not violate Michigan law, the Taubman family's purported blocking position in Taubman Centers may be challenged by Simon Property. Simon Property has filed a motion for preliminary injunction and the Court held a hearing on our motion on March 21, 2003. At that hearing, Simon Property argued that, among other things, the Taubman family's "group" voting power was obtained in violation of Michigan law, that the Taubman family's Series B Preferred Stock was improperly acquired in breach of fiduciary duties owed to Taubman Centers' public shareholders and that the Taubman Centers' Board of Directors has breached, and is continuing to breach, its fiduciary duties to the Taubman Centers' public shareholders. In an Amended Opinion and Order dated May 8, 2003, the Court confirmed its ruling of May 1, 2003 that the Taubman family and certain third parties may not vote their 33.6% controlling block of shares in Taubman Centers unless a majority of disinterested shareholders approve voting rights for those shares. The Court held that the formation of a group in November 2002 by the Taubman family and those parties to vote the 33.6% controlling block of shares was a "control share acquisition" within the meaning of Chapter 7B of the Michigan Business Corporation Act and, therefore, none of the shares comprising the 33.6% block, including the Series B Preferred Stock held by the Taubman family, can be voted unless and until voting rights for those shares have been approved by Taubman Centers' disinterested shareholders. The Court also held that the Taubman Centers board breached its fiduciary duties by enacting a bylaw amendment in December 2002, which makes it more difficult for shareholders to call a special meeting to remove impediments to the joint tender offer of Simon Property Acquisitions, Inc., Simon Property's wholly-owned subsidiary, and Westfield America, Inc. The Court, however, did not reach the merits of Simon Property's claims for breach of fiduciary duty concerning the 1998 issuance of Series B Preferred Stock to the Taubman family, and dismissed those claims on procedural grounds. On May 9, 2003, Taubman Centers filed a notice of appeal and a motion to suspend the injunction.
