On the next two 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.

SIMON PROPERTY GROUP
Reconciliation of NOI to Net Income
As of March 31, 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 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 three months ended March 31, 2004.
