SIMON PROPERTY GROUP

Overview

The Company

Simon Property Group, Inc. (the "Company" or "Simon Property") (NYSE:SPG) is a self-administered and self-managed real estate investment trust ("REIT"). Simon Property Group, L.P. (the "Operating Partnership") is a subsidiary partnership of the Company. The Company and the Operating Partnership (collectively the "Simon Group") are engaged primarily in the ownership, operation, management, leasing, acquisition, expansion and development of real estate properties, primarily regional malls and community shopping centers.

At September 30, 2004, the Company, directly or through the Operating Partnership, owned or had an interest in 244 properties which consisted of regional malls, community shopping centers and office and mixed-use properties (mixed-use properties include a combination of retail, office space or hotel components) containing an aggregate of 188 million square feet of gross leasable area (GLA) in 37 states plus Puerto Rico and Canada. The Company also holds interests in 48 European shopping centers in France, Italy, Poland and Portugal.

Subsequent to quarter-end, on October 14, 2004, the Company completed its $5.1 billion (including the assumption of debt) acquisition of Chelsea Property Group, Inc. ("Chelsea"). Chelsea common shareholders received merger consideration of $36.00 in cash; 0.2936 of a share of Simon common stock; and 0.3000 of a share of Simon 6% Series I convertible perpetual preferred stock for each share of Chelsea common stock. At closing, shares and units were issued as follows:

•: 12,978,795 shares of Simon Property Common Stock
•: 4,652,232 Simon Property Group, L.P. common units
•: 13,261,712 shares of Simon Property 6% Series I Convertible Perpetual Preferred Stock (liquidation value of $50 per share)
•: 4,753,794 Simon Property Group, L.P. 6% Convertible Perpetual Preferred Units (liquidation value of $50 per unit)

Chelsea will operate as a division of SPG out of its current headquarters in Roseland, New Jersey, with David Bloom and the Chelsea management team continuing their leadership. David Bloom has been appointed as an Advisory Director of the Simon Property Group Board of Directors.

Chelsea Property Group is the leading owner, developer and manager of Premium Outlet® centers in the U.S. and Asia. Its portfolio includes 36 Premium Outlet centers (32 in the U.S. and 4 in Japan) located in major metropolitan markets such as New York, Los Angeles and Boston, and tourist destinations such as Orlando, Las Vegas and Palm Springs. The 32 domestic Premium Outlet centers are 98% occupied and generate sales per square foot of approximately $400. Chelsea's four Premium Outlet centers in Japan, located near Tokyo, Osaka and Fukuoka, are fully leased and generate average sales of more than $800 per square foot.

On the next three pages, we present balance sheet and income statement data on a pro rata basis reflecting the Company's proportionate economic ownership of each asset in the Simon Group portfolio.

Basis of Presentation: The consolidated amounts shown are prepared on a consistent basis with the consolidated financial statements prepared by the Company. The Real Estate Joint Ventures column was derived on a property-by-property basis by applying the same percentage interests used to arrive at our share of net income during the period and applying them to all financial statement line items of each property. A similar calculation was performed for minority interests.

Reconciliation of NOI to Net Income
As of September 30, 2004

Industry practice is to evaluate real estate properties on an unleveraged basis. NOI is a standard industry performance measure which is defined as operating income plus depreciation and amortization, both calculated in accordance with accounting principles generally accepted in the United States ("GAAP"). We consider NOI to be a key measure of our operating performance that is not specifically defined by GAAP. We believe that NOI is helpful to investors because it is a widely recognized measure of the performance of REITs and provides a relevant basis for comparison among REITs. We also use NOI internally to measure the operating performance of our portfolio.

However, you should understand that NOI:

—does not represent cash flow from operations as defined by GAAP,

—should not be considered as an alternative to net income determined in accordance with GAAP as a measure of operating performance,

—is not an alternative to cash flows as a measure of liquidity, and

—is not indicative of cash flows from operating, investing and financing activities.

The Reconciliation of NOI to Net Income provides "Total NOI of the Simon Group Portfolio" and reconciles the amounts to net income, which we believe is the most directly comparable GAAP financial measure. The Computation of Comparable Property NOI Growth provides the increase in the comparable regional mall and mixed-use NOI for the nine months ended September 30, 2004.
