NOTES TO FINANCIAL STATEMENTS

NOTE 1:  DESCRIPTION OF PLAN

The following description of The Macerich Property Management Company Profit Sharing Plan and Trust (the “Plan”) provides only general information.  Participants and other interested parties should refer to the Plan agreement for a more complete description of the Plan’s provisions.

General

The Plan is a defined contribution pension plan covering substantially all employees of The Macerich Property Management Company LLC and participating affiliates (the “Company”, the “Employer” and the “Plan Administrator”).  The Plan is subject to regulations set forth by the Department of Labor under the Employee Retirement Income Security Act of 1974 (“ERISA”).

In 2004, the Plan transferred all balances in the Dreyfus Premier Large Company Fund to the UBS S&P 500 Index Fund.

On January 1, 2003, employees who were previously participants in The Westcor Partners 401k Plan were granted eligibility into the Plan.  On August 1, 2003, The Westcor Partners 401K Plan was merged into the Plan and all assets, totaling $5,794,544, were transferred into the Plan.

As of August 1, 2003, the Westcor 401K Plan had 24 participant loans outstanding with a balance totaling $140,428 with interest rates ranging from 5.75% to 10.50%.  The Plan does not allow for participant loans, but was amended to allow these loans to be assumed by the Plan and paid off on their original terms.

On January 1, 2004, the Plan adopted the “Safe Harbor” provisions under Sections 401(k)(12) and 401(m)(11) of the Internal Revenue Code.  In accordance with adopting these provisions, the Company began matching contributions equal to 100 percent of the first 3 percent of compensation deferred by a participant and 50 percent of the next 2 percent of compensation deferred by a participant.

Administration

The Company has designated an Administrative Committee (the “Committee” and the “Trustees”), consisting of Richard Bayer, General Counsel, Arthur Coppola and Thomas O’Hern, officers of the Company.  Among other duties, it is the responsibility of the Committee to select and monitor performance of investments and maintain certain administrative records.  The committee approved MFS Heritage Trust Company (the “Custodian”) to receive plan contributions from the Company and invest and safeguard the Plan’s assets held for investment purposes as directed by the committee.

4

Employee Participation and Eligibility

All employees of the Company may become eligible to participate in the Plan, provided the employee is twenty-one years of age, has completed one year of employment during which at least 1,000 hours of service were provided, and is not covered by a collective bargaining agreement which has made retirement benefits available.  An eligible employee may enter the Plan on January 1, April 1, July 1 or October 1, which follows satisfaction of the eligibility requirements.

The Plan permits employees of newly acquired entities credit for years of service earned prior to Macerich’s ownership.  If this credit for prior service allows the acquisition employee to meet Plan eligibility requirements, they are granted the option of entering the Plan on the first day of the month following their date of hire.

Contributions

Participants are permitted to defer up to 15% of their salary, as defined in the Plan.  The Company may make discretionary contributions to the Plan from the net profits of the current year and accumulated earnings from prior years, in one or more installments.  In no event shall the contribution by the Company exceed fifteen percent (15%) of the participants’ compensation for any Plan year.

Vesting Provisions

The Plan was amended on December 1, 2000 to change the vesting provisions.  Company contributions to the Plan became 100% vested as of January 1, 2001.

Participant Accounts

Each participant’s account is credited with the participant’s contribution and allocations of the Company’s contribution, Plan earnings and forfeitures, and charged with any withdrawals or distributions requested by the participant, investment losses and allocation of administrative expenses, if applicable.  Allocations are based on participant earnings or account balances, as defined.  The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

Benefit Payments

On termination of service due to death, disability, or retirement, a participant may elect to receive either a lump-sum amount equal to the value of the participant’s vested interest in his or her account or installment payments as permitted and defined under the Plan.  For termination of service for other reasons, a participant may receive the value of the vested interest in his or her account as a lump-sum distribution.

The Plan also permits distributions for Hardships, as defined in the Plan.

5

Tax Status

The Plan obtained its latest determination letter on June 10, 2002, in which the Internal Revenue Service stated that the Plan, as amended, is in compliance with the applicable requirements of the Internal Revenue Code.

Plan Expenses

All administrative expenses of the Plan are paid by the Company, or, at the election of the Company, from the Plan trust fund.  For the year ended December 31, 2004, there were no administrative expenses paid from the Plan trust fund.  The investment options have certain management fees, which reduce the overall return on assets.  The net appreciation on investments is reflected net of the management fees.

NOTE 2:  SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying financial statements have been prepared using the accrual basis of accounting in conformity with accounting principles generally accepted in the United States of America.

Investment Valuation and Income Recognition

In compliance with the requirements of ERISA, cash and equity funds are reported at fair value.  The investments and changes therein of the trust funds have been reported to the Plan by the Custodian using fair value.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires Plan management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.

Concentration of Risk

The Plan has exposure to risk to the extent that its investments are subject to market fluctuations that may materially affect the value of the investment balances.

6

Benefits Payable to Former Participants

The American Institute of Certified Public Accountants (AICPA) has issued guidelines regarding amounts due to former Plan participants but not paid by year-end.  The AICPA requires these amounts to be classified as net assets available for Plan benefits, and not as liabilities of the Plan.  Included in net assets available for Plan benefits at December 31, 2004, are amounts which may become payable to participants who are not active participants of the Plan.
