         GENERAL GROWTH PROPERTIES, INC. ANNOUNCES FIRST QUARTER RESULTS

CHICAGO, ILLINOIS, MAY 2, 2005 -- General Growth Properties, Inc. (NYSE: GGP)
today announced first quarter 2005 results. Earnings per share - diluted (EPS)
were $.06 for the first quarter of 2005 as compared to $.27 in the first quarter
of 2004. Fully diluted Funds From Operations per share (FFO) were $.72 for the
first quarter of 2005, a 20% increase over $.60 reported in the comparable
period of 2004.

"The first quarter of 2005 was our first full quarter of combined operations of
The Rouse Company and General Growth," said John Bucksbaum, chief executive
officer, General Growth Properties. "Although we have already captured some
efficiencies, there are still significant benefits we expect to obtain
throughout the remainder of this year and next from the expanded and more
valuable platform that we can now offer to all of our constituents."

FINANCIAL AND OPERATIONAL HIGHLIGHTS


- -    EPS in the first quarter of 2005 was $.06 per share, versus $.27 in the
     comparable period of 2004. Depreciation expense in 2005 was $163.3 million
     or $.69 per share, versus $72.9 million or $.33 per share in 2004.

- -    FULLY DILUTED FFO PER SHARE increased to $.72 in the first quarter of 2005,
     20% above $.60 reported in the first quarter of 2004. TOTAL FFO for the
     quarter increased 28% to $209.6 million, from $163.7 million in the first
     quarter of 2004. The effects of non-cash rental revenue recognized pursuant
     to SFAS No. 141 and 142 resulted in approximately $8.4 million or $.03 of
     FFO per fully diluted share in the first quarter of 2005 as compared to
     $7.4 million or $.03 in the comparable period of 2004. Straight-line rent
     resulted in approximately $21.4 million or $.07 of FFO per fully diluted
     share in the first quarter of 2005, versus $2.9 million or $.01 in the same
     period of 2004. Straight-line rents in 2005 include approximately $10.1
     million or approximately $.04 of FFO per fully diluted share of cumulative
     incremental straight-line rent related to a modification in our recognition
     policies for tenant rent holidays and inducements.

                                       1                             May 2, 2005

- -    FFO GUIDANCE for 2005 remains estimated to be at least $3.13 per share. As
     future short term interest rates cannot be accurately estimated, the
     Company expects to maintain this guidance until the Federal Reserve Board
     discontinues its measured increases of interest rates, or until such
     earlier time, if applicable, that the Company estimates that full year 2005
     FFO per share could be below $3.13.

SEGMENT RESULTS

NON-GAAP SUPPLEMENTAL FINANCIAL MEASURES AND DEFINITIONS
FUNDS FROM OPERATIONS (FFO)

General Growth, consistent with real estate industry and investment community
preferences, uses FFO as a supplemental measure of operating performance for a
real estate investment trust (REIT). The National Association of Real Estate
Investment Trusts (NAREIT) defines FFO as net income (loss) (computed in
accordance with Generally Accepted Accounting Principles (GAAP)), excluding
gains (or losses) from cumulative effects of accounting changes, extraordinary
items and sales of properties, plus real estate related depreciation and
amortization and after adjustments for unconsolidated partnerships and joint
ventures.

The Company considers FFO a supplemental measure for equity REITs and a
complement to GAAP measures because it facilitates an understanding of the
operating performance of the Company's properties. FFO does not give effect to
real estate depreciation and amortization since these amounts are computed to
allocate the cost of a property over its useful life. Since values for
well-maintained real estate assets have historically increased or decreased
based upon prevailing market conditions, the


                                       3                             May 2, 2005



Company believes that FFO provides investors with a clearer view of the
Company's operating performance.

In order to provide a better understanding of the relationship between FFO and
GAAP net income, a reconciliation of FFO to GAAP net income has been provided.
FFO does not represent cash flow from operating activities in accordance with
GAAP, should not be considered as an alternative to GAAP net income and is not
necessarily indicative of cash available to fund cash needs. In addition, the
Company has presented FFO on a consolidated and unconsolidated basis (at the
Company's ownership share) as the Company believes that given the significance
of the Company's operations that are owned through investments accounted for on
the equity method of accounting, the detail of the operations of the Company's
unconsolidated properties provides important insights into the income and FFO
produced by such investments for the Company as a whole.

REAL ESTATE PROPERTY NET OPERATING INCOME (NOI) AND COMPARABLE NOI

General Growth believes that Real Estate Property Net Operating Income (NOI) is
a useful supplemental measure of the Company's operating performance. The
Company defines NOI as operating revenues from continuing operations (rental
income, land sales, tenant recoveries and other income) less property and
related expenses from continuing operations (real estate taxes, land sales
operating costs, repairs and maintenance, marketing and other property
expenses). As with FFO described above, NOI has been reflected on a consolidated
and unconsolidated basis (at the Company's ownership share). Other REITs may use
different methodologies for calculating NOI, and accordingly, the Company's NOI
may not be comparable to other REITs.

Because NOI excludes general and administrative expenses, interest expense,
depreciation and amortization, gains and losses from property dispositions,
discontinued operations, and extraordinary items, it provides a performance
measure that, when compared year over year, reflects the revenues and expenses
directly associated with owning and operating commercial real estate properties
and the impact on operations from trends in occupancy rates, rental rates, land
values and operating costs. This measure thereby provides an operating
perspective not immediately apparent from GAAP operating or net income. The
Company uses NOI to evaluate its operating performance on a property-by-property
basis because NOI allows the Company to evaluate the impact that factors such as
lease structure, lease rates and tenant base, which vary by property, have on
the Company's operating results, gross margins and investment returns.

In addition, management believes that NOI provides useful information to the
investment community about the Company's operating performance. However, due to
the exclusions noted above, NOI should only be used as an alternative measure of
the Company's financial performance. For reference and as an aid in
understanding of

                                       4                             May 2, 2005



management's computation of NOI, a reconciliation of NOI to consolidated
operating income as computed in accordance with GAAP has been presented.

Comparable NOI excludes from both years the NOI of properties with significant
physical or merchandising changes and those properties acquired or opened during
the relevant comparative accounting periods.

PROPERTY INFORMATION

The Company has presented information on its consolidated and unconsolidated
properties separately in the accompanying financial schedules. As a significant
portion of the Company's total operations are structured as joint venture
arrangements which are unconsolidated, management of the Company believes that
operating data with respect to all properties owned provides important insights
into the income produced by such investments for the Company as a whole. In
addition, the individual items of revenue and expense for the unconsolidated
properties have been presented at the Company's ownership share of such
unconsolidated ventures. As the management operating philosophies and strategies
are the same regardless of ownership structure, an aggregate presentation of NOI
and other operating statistics yields a more accurate representation of the
relative size and significance of the elements of the Company's overall
operations.
