These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits of the Plan as of December 31, 2004 and 2003, and the changes in net assets available for plan benefits for each of the years in the three year period ended December 31, 2004 in conformity with accounting principles generally accepted in the United States of America. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of assets (held at end of year) and reportable transactions, together referred to as "supplemental information", are presented for the purpose of additional analysis and are not a required part of the basic financial statements but are supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental information is the responsibility of the Plan's management. The supplemental information has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole.

Summary of Significant Accounting Principles -------------------------------------------- Basis of Presentation PS 401(k) Profit Sharing Plan (the "Plan") encompasses Public Storage, Inc., PS Business Parks, Inc. and their majority owned subsidiaries (the "Company"). Basis of Accounting ------------------- The financial statements of the Plan are prepared under the accrual basis of accounting. Estimates --------- The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Plan administrator to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results may differ from those estimates. Income Tax Status ----------------- The Plan obtained its latest determination letter on March 14, 2003, in which the Internal Revenue Service stated that the Plan, as then designed, was in compliance with the applicable requirements of the Internal Revenue Code. The Plan has been amended since receiving the determination letter. However, the Plan administrator and the Plan's tax counsel believe that the Plan is currently designed and being operated in compliance with the applicable requirements of the Internal Revenue Code. Therefore, no provision for income taxes has been included in the Plan's financial statements. Investment Valuation -------------------- Investments in cash equivalents (liquid funds, money market funds and time deposits) are valued at cost, which approximates fair value. Investments in mutual funds are stated at fair value. All other securities are valued at the last reported sale price on the last business day of the Plan year or at the quoted market price. Interest income is recognized when earned. Dividends are recorded on the ex-dividend date. 2. Description of the Plan ----------------------- The following description of the plan provides only general information. Participants should refer to the Summary Plan Description for a more complete description of the Plan's provisions. Note 9 contains information on key changes to the Plan which were effective January 1, 2005, and impact the topics on eligibility and the Company's contribution. The PS 401(k) Profit Sharing Plan is a defined contribution plan for the benefit of all permanent employees of the Company who have completed at least one year of service and attained 21 years of age. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). Although it has not expressed the intention to do so, the Company has the right to terminate the Plan subject to ERISA provisions. The Plan allows interim allocations of Company contributions and earnings or losses of trust fund assets among participants. Major provisions of the Plan, are as follows: Contributions ------------- Employee contributions to the Plan (voluntary contributions) are deferrals of the employee's compensation made through a direct reduction of compensation in each payroll period. The maximum annual tax deferred contribution, excluding catch-up contributions, amount is limited to $13,000 for 2004 and $12,000 for 2003. Participants may also contribute amounts representing distributions from other qualified benefit or defined contribution plans. The Company contributes 3% of the employee's compensation for all participants in the Plan. Additional profit sharing amounts may be contributed at the option of the Company's board of directors. Contributions are subject to certain limitations. 4 PS 401(k) PROFIT SHARING PLAN NOTES TO FINANCIAL STATEMENTS December 31, 2004 Participant Accounts -------------------- Each participant's account is credited with the participant's contribution, the guaranteed Company contribution and allocations of (a) the Company's profit sharing contribution and (b) Plan earnings, and charged with an allocation of administrative expenses. 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. Vesting ------- Employee deferrals and the 3% guaranteed Company contribution are 100% vested and non-forfeitable. Profit sharing Company contribution balances vest over a seven year period. Generally, each participant's account becomes 10 percent vested (non-forfeitable) after two years of service (as defined), 20 percent after three years of service and an additional 20 percent for each additional year of service thereafter. Upon death, severance by reason of disability, or the attainment of the participant's sixty-fifth birthday, a participant automatically becomes fully vested to the extent of the balance in their account. In the event the Plan is terminated or contributions are completely discontinued, each participant becomes fully vested. Investment Options ------------------ For the year ended December 31, 2004, upon enrollment in the Plan, a participant may direct contributions in any of the following twenty-two investment options: 1. Highmark Div. Money Market 12. American Funds Growth Fund R3 2. Strong Government Securities 13. AIM Opportunities A 3. BGI Lifepath Income Fund R 14. AIM Small CAP Growth A 4.

P.S. Business Parks Stock 11. Janus Adv CAP Appreciation 22. Scudder Real Estate Participants may change their investment options at any time. Distributions from the Trust Fund --------------------------------- Distributions of each participant's vested account balance upon severance or death are made in a single lump sum payment; or if the participant's vested account balance exceeds $5,000, payment may be deferred until April 1st of the calendar year in which the participant reaches 70 1/2 years of age. Additionally, the Plan provides for hardship distributions (as defined) at the discretion of the Plan Administrative Committee. 5 PS 401(k) PROFIT SHARING PLAN NOTES TO FINANCIAL STATEMENTS December 31, 2004 Generally, distributions are made no later than 60 days after the close of the Plan year in which the participant becomes eligible for such distributions. Under certain circumstances, participants enrolled in the Plan prior to and including December 31, 1983 may elect alternative distribution methods. Forfeited Accounts ------------------ Forfeitures of profit sharing contributions will be used to reduce the Company's contribution for profit sharing contributions, guaranteed Company contributions or guaranteed matching contributions. At December 31, 2004 and 2003, forfeited nonvested amounts were approximately $1,254,000 and $729,000, respectively. These accounts will be allocated to individual participant's accounts in the ratio that each such eligible participant's compensation bears to the total compensation of all such eligible participants in the plan year the forfeitures are used. 3. Investments ----------- Union Bank has custody of the investments under a non-discretionary trust agreement with the Plan. The following table presents the fair value of investments.

Risks and Uncertainties ----------------------- The Plan provides for various investment options in any combination of equity, fixed income, and other investment securities. Investment securities are exposed to various risks, such as interest rate, market, and credit. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks in the near term could materially affect participants' account balances and the amounts reported in the statements of net assets available for benefits and the statement of changes in net assets available for benefits. 8. Concentrations -------------- Investments in the Company's securities comprised approximately of 46% and 45% of the Plan's total investments as of December 31, 2004 and 2003, respectively. 7 PS 401(k) PROFIT SHARING PLAN NOTES TO FINANCIAL STATEMENTS December 31, 2004 9.
