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, 2004, we owned or held an interest in 246 income-producing properties in North America, which consisted of 174 regional malls,
68 community shopping centers, and four office and mixed-use properties in 37 states and Canada (collectively, the "Properties", and individually, a "Property").
Mixed-use properties are properties that include a combination of retail, office, and/or hotel components. We also own interests in three parcels of land held for future development
(together with the Properties, the "Portfolio"). In addition, we have ownership interests in 48 shopping centers in Europe (France, Italy, Poland and Portugal).

M.S.
Management Associates, Inc. (the "Management Company") is a wholly-owned subsidiary that provides leasing, management, and development services to most of the Properties. In
addition, insurance subsidiaries of the Management Company insure the self-insured retention portion of our general liability program and the deductible associated with our workers'
compensation programs. In addition, they provide reinsurance for the primary layer of general liability coverage to our third party maintenance providers while performing services under contract with
us. Third party providers provide coverage above the insurance subsidiaries' limits.

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, the rules and regulations of the Securities and Exchange Commission, and the accounting policies described in our financial statements
for the year ended December 31, 2003 as filed with the Securities and Exchange Commission. 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, 2004
are not necessarily indicative of the results to be obtained for the full fiscal year.

As
of March 31, 2004, of our 246 Properties we consolidated 155 wholly-owned Properties and 17 less than wholly-owned Properties which we control or which we consolidated in
accordance with FIN 46 (see Note 10), and we accounted for 74 Properties using the equity method. We manage the day-to-day operations of 63 of the 74 equity
method Properties. We account for our interests in our two European joint ventures that hold the 48 shopping centers in Europe using the equity method.

We
allocate our net operating results after preferred distributions based on our partners' respective ownership interests. In addition, Simon Property owns certain of our preferred
units. Simon Property's weighted average ownership interest in the Operating Partnership was as follows:

For the Three Months Ended March 31,2004

200376.8%

74.8%


6

---



Simon Property's ownership interest in the Operating Partnership as of March 31, 2004 was 77.2% and at December 31, 2003 was 76.8%.
We adjust the limited partners' interest at the end of each period to reflect changes in their ownership interest in the Operating Partnership.

The
statements of operations and comprehensive income for the period ended March 31, 2003 have been reclassified to reflect the disposition of 13 properties sold during 2003.

3.     Per Unit Data

We determine basic earnings per unit based on the weighted average number of units outstanding during the period. We determine diluted earnings per unit based on
the weighted average number of units outstanding combined with the incremental weighted average units that would have been outstanding assuming all dilutive potential common units were converted into
units at the earliest date possible. The following table sets forth the computation for our basic and diluted earnings per unit.

|                                 |  | For The Three Months Ended March 31,
|-------------------------------- |  | ------------------------------------
|
|Weighted Average Units  Basic   |  | 261,165,853                         
|Effect of stock options          |  | 964,418                             
|                                 |  |                                     
|Weighted Average Units  Diluted |  | 262,130,271                         
|                                 |  |                                     

For the period ending March 31, 2004, potentially dilutive securities include certain preferred units of limited partnership interest of
the Operating Partnership which are exchangeable for common stock. However, these securities were not dilutive during any period presented.

4.     Cash and Cash Flow Information

Our balance of cash and cash equivalents as of March 31, 2004 included $100.7 million and as of December 31, 2003 included
$174.8 million related to our gift card and certificate programs, 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 properties and diversify our risk in a particular property or trade area.
We also use joint ventures in the development of new properties. We held joint venture ownership interests in 74 Properties as of March 31, 2004 and 76 as of December 31, 2003. Two joint
venture properties previously accounted for under the equity method were consolidated upon adoption of FIN 46 (see Note 10). We also held joint venture interests in 48 European shopping
centers as of March 31, 2004 and 47 as of December 31, 2003. Since we do not fully control these joint venture Properties, accounting principles generally accepted in the United States
currently require that we account for these Properties on the equity method. See Note 10 for discussion on the impact of new accounting pronouncements on consolidation principles. Substantially
all of our joint venture Properties are subject to rights of first refusal, buy-sell provisions, or other sale rights for 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 sale of or the use of available cash or borrowings to acquire 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 follows. This information includes Mall of America
(see Note 8). We condensed into separate line items major captions of the statements of operations for joint venture interests sold or consolidated. Consolidation occurs when we acquire an
additional interest in the joint venture and as a result, gain unilateral control of the

Property.
We reclassified these line items into "Discontinued Joint Venture Interests", so that we may present results of operations for those joint venture interests held as of March 31, 2004.

"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.

6.     Debt

On January 15, 2004, we paid off $150.0 million of 6.75% unsecured notes that matured on that date with borrowings from our Credit Facility. On
February 9, 2004, we paid off $300.0 million of 6.75% unsecured notes that matured on that date with borrowings from our Credit Facility.

On
January 20, 2004, 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 4.21%. The first tranche is $300.0 million at a fixed interest rate of 3.75% due January 30, 2009 and the second tranche is $200.0 million at a fixed
interest rate of 4.90% due January 30, 2014. We received net proceeds of $383.4 million and we exchanged our $113.1 million Floating Rate Mandatory Extension Notes ("MAXES") with
the holder. The MAXES were due November 15, 2014 and bore interest at LIBOR plus 80 basis points. The exchange of the MAXES for the notes instruments did not result in a significant
modification of the terms in the debt arrangement. We used $277.0 million of the net proceeds to reduce borrowings on our $1.25 billion unsecured credit facility (the "Credit Facility"),
to unencumber one Property, and the remaining portion was used for general working capital purposes. On April 30, 2004, we commenced an exchange offer pursuant to a registration statement under
the Securities Act of 1933 offering to exchange registered notes notes for the Rule 144A notes. The exchange notes and the Rule 144A notes have the same economic terms and conditions.

Concurrently
with the pricing of the notes, we entered into a five-year variable rate $300.0 million notional amount swap agreement to effectively convert the
$300.0 million tranche to floating rate debt at an effective rate of

six-month
LIBOR. We completed this swap agreement, as our amount of variable rate indebtedness as a percent of our total outstanding was lower than our desired range.

On
January 22, 2004, we paid off a $60.0 million variable rate mortgage, at LIBOR plus 125 basis points, that encumbered one consolidated Property with proceeds from the
senior unsecured notes mentioned above. In addition, we refinanced another consolidated mortgaged Property with a $32.0 million 6.05% fixed rate mortgage that matures on February 11,
2014. The balance of the previous mortgage was $34.7 million at a variable rate of LIBOR plus 250 basis points and was scheduled to mature on April 1, 2004.

On
February 26, 2004, we obtained a $250.0 million unsecured term loan with an initial maturity date of April 1, 2005. The maturity date may be extended, at our
option, for two, one-year extension periods. The unsecured term loan bears interest at LIBOR plus 65 basis points. The proceeds from this financing were used to pay off our
$65.0 million unsecured term loan that matured on March 15, 2004 and our $150 million unsecured term loan that matured on February 28, 2004. The remaining proceeds were
used for general working capital purposes. The $65.0 million unsecured term loan bore interest at LIBOR plus 80 basis points and the $150.0 million unsecured term loan bore interest at
LIBOR plus 65 basis points.

On
March 31, 2004, we secured an $86.0 million variable rate mortgage, at LIBOR plus 95 basis points, that encumbers Gateway Shopping Center that was acquired on
February 5, 2004 (see Note 9). The mortgage has an original maturity date of March 31, 2005 with three, one-year, extensions available at our option.

7.     Partners' Equity

On March 5, 2004, we issued 380,700 units to Simon Property in connection with Simon Property's issuance of 380,700 shares of restricted stock that were
awarded under The Simon Property Group 1998 Stock Incentive Plan at a value of $56.29 per share. The fair market value of the restricted stock awarded has been deferred and is being amortized over the
four year vesting period.

On
March 25, 2004, one of the limited partners exchanged a total of 1,021,822 units for 1,021,822 shares of common stock of Simon Property.

We
issued 171,313 units to Simon Property related to employee stock options exercised during the first three months of 2004. We used the net proceeds from the option exercises of
approximately $4.4 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 by Teachers. On August 12, 2002, the court granted in part and
denied in part motions for partial summary judgment filed by the parties.

Trial
on all of the equitable claims in this matter began June 2, 2003. On September 10, 2003, the court issued its decision in a Memorandum and Order (the "Order"). In
the Order, the court found that certain entities and individuals breached their fiduciary duties to Triple Five. The court did not award Triple Five damages but instead awarded Triple Five equitable
and other relief and imposed a constructive trust on that portion of the Mall of America owned by us. Specifically, as it relates to us, the court ordered that Triple Five was entitled to purchase
from us the one-half partnership interest that we purchased from Teachers in October 1999, provided Triple Five remits to us the sum of $81.38 million within nine months of
the Order. The court further held that we must disgorge all "net profits" that we received as a result of our ownership interest in the Mall from October 1999 to the present. The court

10

---



appointed
a Special Master to, among other things, calculate "net profits," and, on May 3, 2004, the Special Master issued a memorandum order regarding "net profits."

We
disagree with many aspects of the Order and have appealed the Order to the United States Court of Appeals for the Eighth Circuit. We are also seeking a stay of the Order pending
appeal. Although the district court has denied our motion for a stay, we will be filing a motion in the Eighth Circuit to stay pertinent provisions of the Order pending appeal. We also disagree with
many aspects of the Special Master's May 3, 2004 memorandum and will appeal those findings. It is not possible to provide an assurance of the ultimate outcome of the litigation.

As
a result of the Order, we initially recorded a $6.0 million loss in 2003. In 2004, as a result of the May 3, 2004 memorandum issued by the Special Master, we recorded
an additional loss of $13.5 million that is included in "(Loss) gain on sales of assets and other, net" in the accompanying statements of operations and comprehensive income. We have ceased
recording any contribution to either net income or Funds from Operations ("FFO") from the results of operations of Mall of America since September 1, 2003.

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, 2004, we have guaranteed or have provided letters of credit to support $81.3 million of our total $2.8 billion share of joint venture mortgage and other indebtedness in
the event the joint venture partnership defaults under the terms of the mortgage or other indebtedness. In April 2004, we were released from our guarantee of $17.1 million as the result
of a refinancing of a mortgage of one joint venture property. The mortgages and other indebtedness guaranteed are secured by the property of the joint venture partnership which could be sold in order
to satisfy the outstanding obligation.

9.     Real Estate Acquisitions and Dispositions

On February 5, 2004, we purchased a 95% interest in Gateway Shopping Center in Austin, Texas, for approximately $107.0 million. We funded this
transaction with borrowings on our Credit Facility and with the issuance of 120,671 units valued at approximately $6.0 million. The purchase accounting for this acquisition is still
preliminary.

On
April 27, 2004, we increased our ownership in Bangor Mall in Bangor, Maine from 32.6% to 67.6% and increased our ownership in Montgomery Mall in Montgomery, Pennsylvania from
23.1% to 54.4%. We acquired these additional ownership interests from our partner in the properties for approximately $67 million.

On
May 4, 2004, we acquired Plaza Carolina in San Juan, Puerto Rico for approximately $309 million.

10.   New Accounting Pronouncements

In January 2003, the FASB issued Interpretation No. 46, "Consolidation of Variable Interest Entities, an Interpretation of Accounting Research
Bulletin No. 51" ("FIN 46"). FIN 46 requires the consolidation of entities that meet the definition of a variable interest entity in which an enterprise absorbs the majority of
the entity's expected losses, receives a majority of the entity's expected residual returns, or both, as a result of ownership, contractual or other financial interests in the entity. Our joint
venture interests in variable interest entities consist of real estate assets and are for the purpose of owning, operating and/or developing real estate. Our property partnerships rely primarily on
financing from third party lenders, which is secured by first liens on the Property of the partnership and partner equity. Our maximum exposure to loss as a result of our involvement in these
partnerships is represented by the carrying amount of our investments in unconsolidated entities as disclosed on the accompanying balance sheets plus our guarantees of joint venture debt as disclosed
in Note 8.

We
adopted FIN 46 on January 1, 2004 for variable interest entities that existed prior to February 1, 2003 and as a result we have consolidated two joint venture
properties consisting of two regional malls. The aggregate carrying amount of the investment property for these properties was approximately $166.0 million as of March 31, 2004.

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 and fluctuations in
exchange rates of foreign currencies. 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, 2004, we owned or held an interest in 246 income-producing properties in North America, which consisted of 174 regional malls,
68 community shopping centers, and four office and mixed-use properties in 37 states and Canada (collectively, the "Properties", and individually, a "Property"). Mixed-use
properties are properties that include a combination of retail, office, and/or hotel components. We also own interests in three parcels of land held for future development (together with the
Properties, the "Portfolio"). In addition, we have ownership interests in 48 shopping centers in Europe (France, Italy, Poland and Portugal).



We seek growth in our earnings and cash flow through:

12

---



We
derive our liquidity primarily from our leases that generate positive net cash flow from operations and distributions from unconsolidated entities that totaled $148.3 million
during the first quarter of 2004. In addition, we generate the majority of our revenues from leases with retail tenants including:

Revenues
of M.S. Management Associates, Inc. (the "Management Company"), after intercompany eliminations, consist primarily of management, leasing and development fees that are
typically based upon the size and revenues of the joint venture property being managed. Finally, we also generate revenues from outlot land sales.



Our core business fundamentals remained healthy during the first quarter of 2004. Regional mall comparable sales per square foot ("psf") strengthened during the
first quarter of 2004, increasing 5.5% to $411 psf from $390 psf the same period in 2003, as the overall economy begins to show signs of recovery and as a result of our ongoing dispositions of lower
quality Properties. Our regional mall average base rents increased 4.7% to $32.72 psf as of March 31, 2004 from $31.24 psf as of March 31, 2003. Our regional mall leasing spreads were
$6.27 psf as of March 31, 2004 compared to $12.24 psf as of March 31, 2003. The regional mall leasing spread as of March 31, 2004 includes new store leases signed at an average of
$38.57 psf initial base rents as compared to $32.30 psf for store leases terminating or expiring in the same period. Our same store leasing spread as of March 31, 2004 was $5.02 or a 13.3%
growth rate and is calculated by comparing leasing activity completed in 2004 with the prior tenants rents for those exact same spaces. Finally, our regional mall occupancy was down by 70 basis points
to 91.0% as of March 31, 2004 from 91.7% as of March 31, 2003 primarily due to retailer bankruptcy-related closings during the fourth quarter of 2003 and the first quarter 2004. We
expect to retenant the majority of these spaces lost to bankruptcy during the remaining months of 2004.

During
the first quarter of 2004, we purchased a 95% interest in Gateway Shopping Center in Austin, Texas. In addition, we lowered our overall borrowing rates by 20 basis points during
the first quarter of 2004 as a result of our financing activities related to indebtedness. Our financing activities were highlighted by the following significant transactions:



The Portfolio data discussed in this overview includes the following key operating statistics: occupancy; average base rent per square foot; and comparable sales
per square foot. We include acquired Properties in this data beginning in the year of acquisition and we do not include any Properties located outside of North America. The following table sets forth
these key operating statistics for:

Occupancy Levels and Average Base Rents.Occupancy and average base rent is based on
mall and freestanding GLA owned by us ("Owned GLA") at mall and freestanding stores in the regional malls and all tenants at community shopping centers. We believe the continued stability in regional
mall occupancy is primarily the result of the overall quality of our Portfolio. The result of the stability in occupancy is a direct or indirect increase in nearly every category of revenue. Our
portfolio has maintained high levels of occupancy and increased average base rents in various economic climates.

Comparable Sales per Square Foot.Sales volume includes total reported retail sales at Owned GLA in the
regional malls and all
reporting tenants at community shopping centers. Retail sales at Owned GLA affect revenue and profitability levels because sales determine the amount of minimum rent that can be charged, the
percentage rent realized, and the recoverable expenses (common area maintenance, real estate taxes, etc.) that tenants can afford to pay.

Results of Operations

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

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

In
addition, as a result of the adoption of Interpretation No. 46, "Consolidation of Variable Interest Entities, an Interpretation of Accounting Research Bulletin No. 51"
("FIN 46") on January 1, 2004, we consolidated the operations of two properties, which were accounted for under the equity method in 2003. For the purposes of the following comparison
between the three months ended March 31, 2004 and March 31, 2003, the above transactions, including the impact of the adoption of FIN 46, are 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 periods.

Our
discontinued operations resulted from the sale of the following Properties in 2003 (date of sale):

In
addition to the Property Transactions, on March 14, 2003, we purchased the remaining ownership interest in Forum Shops for $174.0 million in cash and assumed the
minority interest partner's $74.2 million share of debt that impacted our minority interest expense, depreciation expense, and interest expense.



Minimum rents, excluding rents from our consolidated Simon Brand and Simon Business initiatives, increased $25.2 million during the period. The net effect
of the Property Transactions increased minimum rents $15.7 million and the purchase accounting estimation of the fair market value of in-place leases as part of our acquisitions,
increased rents by $3.6 million. Comparable rents increased $5.9 million. This was primarily due to the leasing of space at higher rents that resulted in an increase in base rents of
$4.4 million. In addition, rents from carts, kiosks, and renting unoccupied in-line space increased comparable rents from temporary tenant income by $1.8 million. Overage
rents increased $1.3 million reflecting strengthening retail sales.

Management
fees and other revenues decreased $0.9 million due to lower leasing, construction and development fees due to decreased joint venture development and related
activities. Total other income, excluding consolidated Simon Brand and Simon Business initiatives, was flat during the comparative period.

Consolidated
revenues from Simon Brand and Simon Business initiatives increased $8.5 million to $25.8 million from $17.3 million. The increase in revenues is
primarily due to:

The
increased revenues from Simon Brand and Simon Business were offset by a $2.0 million increase in Simon Brand expenses that primarily resulted from increased gift card and
other operating expenses included in property operating expenses.

Tenant
reimbursements increased $14.4 million of which the Property Transactions accounted for $8.6 million. The remaining increase was primarily due to increases in
comparable recoverable expenditures resulting primarily from higher real estate tax refunds in 2003 than in 2004. Depreciation and amortization expenses increased $17.8 million primarily due to
the net effect of the Property Transactions and the Forum Shops acquisition. Other expenses increased $3.0 million primarily due to ground rent expense of $1.3 million due to the
acquisition of Stanford Shopping Center.

Interest
expense increased $2.2 million. Our average borrowings increased as a result of the impact of the unsecured note offering in January of 2004, and financing of
acquisition activities in 2003 and 2004. This increase was offset by an overall decrease in weighted average interest rates as a result of refinancing activity and an increase in capitalized interest
due to increased development, renovation and expansion activity. Minority interest expense decreased $1.0 million due to the purchase of the remaining partnership interest in Forum Shops.

The
loss on sale of assets in 2004 of $13.5 million reflects our estimate of the financial impact to us from complying with the May 3, 2004 memorandum issued by the
Special Master related to Mall of America litigation (see Note 8).

Income
from unconsolidated entities decreased $4.3 million in 2004 as compared to 2003 resulting from:

Our
preferred unit requirement decreased $5.8 million due to the conversion of 6.5% Series B Preferred Units into common units in the fourth quarter of 2003. This was
offset in part by the issuance of preferred units in connection with the Kravco acquisition in the same quarter.

Liquidity and Capital Resources

Our balance of cash and cash equivalents decreased $44.6 million to $484.5 million as of March 31, 2004, including a balance
of $100.7 million related to our gift card and certificate programs, which we do not consider available for general working capital purposes.

On
March 31, 2004, the Credit Facility had available borrowing capacity of $715.9 million net of outstanding borrowings of $510.0 million and letters of credit of
$24.1 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 date of April 2005, with an additional one-year extension available at our
option. In addition, our Credit Facility has a $100 million EURO sub-tranche that provides availability to borrow Euros at EURIBOR plus 65 basis points and/or dollars at LIBOR plus
65 basis points, at our option, and has the same maturity date as the overall Credit Facility. The amount available under the $100 million EURO sub-tranche will vary with changes in
the exchange rate, however, we may also borrow the amount available under this EURO sub-tranche in dollars, if necessary.

During
the first three months of 2004, the maximum amount outstanding under the Credit Facility was $530.7 million and the weighted average amount outstanding was
$410.8 million. The weighted average interest rate was 1.74% for the three-month period ended March 31, 2004.

We
and/or Simon Property also have access to public equity and long term unsecured debt markets and 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 our current corporate rating is BBB+ by Standard & Poor's.



Our net cash flow from operating activities and distributions of capital from unconsolidated entities totaled $148.3 million. This cash flow includes
$24.4 million of excess proceeds from refinancing activities from one unconsolidated joint venture. In addition, we had net proceeds from all of our debt financing and repayment
activities of $201.7 million as discussed below in Financing and Debt. We used a portion of these proceeds to fund the acquisition of Gateway Shopping Center. We also:

In
general, we anticipate that cash generated from operations will be sufficient to meet operating expenses, monthly debt service, recurring capital expenditures, and distributions to
unitholders necessary to maintain Simon Property's REIT qualification for 2004 and on a long-term basis. 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:

On January 20, 2004, 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 4.21%. The first tranche is $300.0 million at a fixed interest rate of 3.75% due January 30, 2009 and the second
tranche is $200.0 million at a fixed interest rate of 4.90% due January 30, 2014. We received net proceeds of $383.4 million and we exchanged our $113.1 million Floating
Rate Mandatory Extension Notes ("MAXES") with the holder. The MAXES were due November 15, 2014 and bore interest at LIBOR plus 80 basis points. The exchange of the MAXES for the notes
instruments did not result in a significant modification of the terms in the debt arrangement. We used $277.0 million of the net proceeds to reduce borrowings on our $1.25 billion
unsecured credit facility (the "Credit Facility"), to unencumber one Property, and the remaining portion was used for general working capital purposes. On April 30, 2004, we commenced an
exchange offer pursuant to a registration statement under the Securities Act of 1933 offering to exchange registered notes for the Rule 144A notes. The exchange notes and the Rule 144A
notes have the same economic terms and conditions.

Concurrently
with the pricing of the notes, we entered into a five-year variable rate $300.0 million notional amount swap agreement to effectively convert the
$300.0 million tranche to floating rate debt at an effective rate of six-month LIBOR. We completed this swap agreement, as our amount of variable rate indebtedness as a percent of
our total outstanding was lower than our desired range.

On
January 15, 2004, we paid off $150.0 million of 6.75% unsecured notes that matured on that date with borrowings from our Credit Facility. On February 9, 2004, we
paid off $300.0 million of 6.75% unsecured notes that matured on that date with borrowings from our Credit Facility.

On
February 26, 2004, we obtained a $250.0 million unsecured term loan with an initial maturity date of April 1, 2005. The maturity date may be extended, at our
option, for two, one-year extension periods. The unsecured term loan bears interest at LIBOR plus 65 basis points. The proceeds from this financing were used to pay off our
$65.0 million unsecured term loan that matured on March 15, 2004 and our $150 million unsecured term loan that matured on February 28, 2004. The remaining proceeds were
used for general working capital purposes. The $65.0 million unsecured term loan bore interest at LIBOR plus 80 basis points and the $150.0 million unsecured term loan bore interest at
LIBOR plus 65 basis points.



On January 22, 2004, we paid off a $60.0 million variable rate mortgage, at LIBOR plus 125 basis points, that encumbered one consolidated Property
with remaining proceeds from the senior unsecured notes mentioned above. In addition, we refinanced another consolidated mortgaged Property with a $32.0 million 6.05% fixed rate mortgage that
matures on February 11, 2014. The balance of the previous mortgage was $34.7 million at a variable rate of LIBOR plus 250 basis points and was scheduled to mature on April 1,
2004.

On
March 31, 2004, we secured an $86.0 million variable rate mortgage, at LIBOR plus 95 basis points, that encumbers Gateway Shopping Center that was acquired on
February 5, 2004. The mortgage has an original maturity date of March 31, 2005 with three, one-year extensions available at our option.

As of March 31, 2004, we had interest rate cap protection agreements on $296.0 million of consolidated variable rate debt. We had
interest rate protection agreements effectively converting variable rate debt to fixed rate debt on $133.1 million of consolidated variable rate debt. In addition, we hold
€150 million of notional amount fixed rate swap agreements that have a weighted average pay rate of 2.12% and a weighted average receive rate of 2.05% at March 31, 2004.
We also hold $370.0 million of notional amount variable rate swap agreements that have a weighted average pay rate of 1.14% and a weighted average receive rate of 3.72% at March 31,
2004. As of March 31, 2004, the net effect of these agreements effectively converted $54.3 million of fixed rate debt to variable rate debt. As of December 31, 2003, the net
effect of these agreements effectively converted $237.0 million of fixed rate debt to variable rate debt.

Contractual Obligations and Off-Balance Sheet Arrangements:There have been no material changes in our outstanding
capital expenditure commitments since December 31, 2003, as previously disclosed in our Management's Discussion and Analysis of Financial Condition and Results of Operations for the year ended
December 31, 2003 as filed with the Securities and Exchange Commission for the year ended December 31, 2003. The following table summarizes the material aspects of our future obligations

We expect to meet our 2004 debt maturities through refinancings, the issuance of new debt securities or borrowings on the Credit Facility. We
expect to have the ability and financial resources to meet all future long-term obligations. Specific financing decisions will be made based upon market rates, property values, and our
desired capital structure at the maturity date of each transaction.

Our
off-balance sheet arrangements consist primarily of our investments in real estate joint ventures which are common in the real estate industry and are described in
Note 5 of the notes to the accompanying financial statements. 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, 2004, we have guaranteed or have provided letters of credit to support $81.3 million of our total $2.8 billion share of joint
venture mortgage and other indebtedness presented in the table above. In April 2004, we were released from our guarantee of $17.1 million as the result of a joint venture property
refinancing its mortgage.

Acquisitions.We acquired a 95% interest in Gateway Shopping Center located in Austin, Texas. The total
consideration paid for
this transaction was approximately $107.0 million and consisted of:

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. Our 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 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 any such sale to reduce outstanding indebtedness.

Dispositions.As part of our strategic plan to own quality retail real estate we continue to pursue the
sale of Properties,
under the right circumstances, 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.



New Developments.The following describes our new development projects, the estimated total cost, and our
share of the
estimated total cost and our share of the construction in progress balance as of March 31, 2004 (dollars in millions):

We expect to fund these capital projects with either available cash flow from operations, borrowings from our Credit Facility, or project specific
construction loans. We expect total 2004 new development costs during the year to be approximately $200 million.

We have other renovation and/or expansion projects currently under construction or in preconstruction development and expect to invest a total of
approximately $250 million on expansion and renovation activities in 2004.

International.Our strategy is to invest capital internationally not only to acquire existing properties
but also to use the
net cash flow from the existing properties to fund other future developments. We believe reinvesting the cash flow derived in Euros in other Euro denominated development and redevelopment projects
helps minimize our exposure to our initial investment and to the changes in the Euro on future investments that might otherwise significantly increase our cost and reduce our returns on these new
projects and developments. In addition, to date we have funded the majority of our investments in Europe, with Euro-denominated borrowings that act as a natural hedge on our investments.

Currently,
our net income exposure to changes in the volatility of the Euro is not material. In addition, since cash flow from operations is currently being reinvested in other
development projects, we do not expect to repatriate Euros for the next few years. Therefore, we also do not currently have a significant cash flow from operations exposure due to fluctuations in the
value of the Euro.

The
agreements for our 36.0% interest in European Retail Enterprises, B.V. ("ERE") are structured to allow us to acquire an additional 24.7% 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 $55 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 2006-2008.

The
carrying amount of our total equity method investments as of March 31, 2004 in European subsidiaries net of the related cumulative translation adjustment was
$302.5 million, including subordinated debt in ERE. Currently a total of 7 developments are under construction that will add approximately 5.3 million square feet of GLA for a total net
cost to the joint ventures of approximately €345 million, of which our share is approximately €145 million.



The Board of Directors of Simon Property, acting as our general partner, declared and we paid a distribution of $0.65 per unit in the first quarter of 2004. 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
Simon Property's 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.

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 approximately 187,000 square feet of mall shop tenants during the first quarter of 2004. We expect 2004 to be similar to 2003 in terms
of square feet lost to bankruptcies.

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 1.9% of total GLA or more than 4.6% 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 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
Management's Discussion and Analysis of Financial Condition and Results of Operations for the year ended December 31, 2003 as filed with the Securities and Exchange Commission for the year
ended December 31, 2003. There have been no material changes in the assumptions used or results obtained regarding market risk since December 31, 2003.

Item 4.    Controls and Procedures

Evaluation of Disclosure Controls and Procedures.We carried out an evaluation under the supervision and
with participation of
management, including the chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period
covered by this Quarterly Report on Form 10-Q pursuant to Exchange Act Rule 13a-15. Based upon that evaluation, our management, including the chief executive
officer and chief financial officer, concluded that our disclosure controls and procedures were effective as of that date.

Changes in Internal Control Over Financial Reporting.There was no change in our internal control over
financial reporting (as
defined in Rule 13a-15(f)) that occurred during the first quarter of 2004 that has materially affected, or is reasonably likely to materially affect, our internal control over
financial reporting.

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 by Teachers. On August 12, 2002, the court granted in part and denied in part motions
for partial summary judgment filed by the parties.

Trial
on all of the equitable claims in this matter began June 2, 2003. On September 10, 2003, the court issued its decision in a Memorandum and Order (the "Order"). In
the Order, the court found that certain entities and individuals breached their fiduciary duties to Triple Five. The court did not award Triple Five damages but instead awarded Triple Five equitable
and other relief and imposed a constructive trust on that portion of the Mall of America owned by us. Specifically, as it relates to us, the court ordered that Triple Five was entitled to purchase
from us the one-half partnership interest that we purchased from Teachers in October 1999, provided Triple Five remits to us the sum of $81.38 million within nine months of
the Order. The court further held that we must disgorge all "net profits" that we received as a result of our ownership interest in the Mall from October 1999 to the present. The court
appointed a Special Master to, among other things, calculate "net profits," and, on May 3, 2004, the Special Master issued a memorandum order regarding "net profits."

We
disagree with many aspects of the Order and have appealed the Order to the United States Court of Appeals for the Eighth Circuit. We are also seeking a stay of the Order pending
appeal. Although the district court has denied our motion for a stay, we will be filing a motion in the Eighth Circuit to stay pertinent provisions of the
Order pending appeal. We also disagree with many aspects of the Special Master's May 3, 2004 memorandum and will appeal those findings. It is not possible to provide an assurance of the
ultimate outcome of the litigation.

As
a result of the Order, we initially recorded a $6.0 million loss in 2003. In 2004, as a result of the May 3, 2004 memorandum issued by the Special Master, we recorded
an additional loss of $13.5 million that is included in "(Loss) gain on sales of assets and other, net" in the accompanying statements of operations and comprehensive income. We have ceased
recording any contribution to either net income or Funds from Operations ("FFO") from the results of operations of Mall of America.



On
February 5, 2004, we issued 120,671 units valued at approximately $6.0 million in connection with our purchase of a 95% interest in Gateway Shopping Center in Austin,
Texas, for approximately $107.0 million. We funded the remaining purchase price with borrowings on our Credit Facility. We issued these units without registration under the Securities Act of
1933, as amended, in reliance on Section 4(2) of that Act.

During
the first three months of 2004, we issued 380,700 units to Simon Property in connection with Simon Property's issuance of 380,700 shares of restricted stock that were awarded
under The Simon Property Group 1998 Stock Incentive Plan at a value of $56.29 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 171,313 units to Simon Property related to employee stock options exercised during the first three months of 2004. We used the net proceeds from the option exercises of
approximately $4.4 million for general working capital purposes. We issued all such units without registration under the Securities Act of 1933, as amended, in reliance on Section 4(2)
of that Act.
