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 auditing standards generally accepted in the United States of America. 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, 2001 and 2000, and the changes in net assets available each of the years in the three year period ended December 31, 2001 in conformity with accounting principles generally accepted in the United States of America. Our audits were made for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of assets held for investment purposes, party-in-interest transactions and reportable transactions are presented for purposes of complying with the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974 and are not a required part of the basic financial statements. The supplemental schedules have 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. /s/ Link, Murrel & Co.

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 using the accrual method of accounting. Estimates --------- The preparation of financial statements in conformity with generally accepted accounting principles 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 is patterned after a prototype plan which was determined to qualify under Section 401(a) of the Internal Revenue Code (the Code) and, therefore, is exempt from federal income taxes under Section 501(a) of the Code. The Plan is exempt from state taxes under similar statutes. The Plan was amended on December 29, 1994 to comply with the 1986 Tax Reform Act. A determination letter was received on January 10, 1996 from the Internal Revenue Service to inform the Company that the amended Plan is qualified and the trust established under the Plan is tax-exempt under the appropriate sections of the Code. On April 1, 1996, the Plan was amended to provide a hardship distribution provision. On December 29, 1997, the Plan was amended to include employees on leave of absence as eligible participants. On January 1, 2001, the plan effected a 401(K) Safe Harbor Plan amendment which is determined to qualify under Section 401(K) of the Code. 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 Code. Therefore, no provision for income taxes has been included in the Plan's financial statements. 4 1. Summary of Significant Accounting Principles (continued) -------------------------------------------------------- Investment Valuation -------------------- On January 1, 2001, the Plan's administrative committee (the Committee) transferred the Plan's assets from Wells Fargo Bank to Salomon Smith Barney. 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 quoted market price. Interest and dividend income is recognized when earned. Unrealized gains and losses result from the change in the fair value of investments held at both the beginning and end of the year, the difference between cost and year-end fair value for investments acquired during the year, and adjustments for unrealized gains and losses previously recognized on investments sold during the year. 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. The PS 401(K)/Profit Sharing Plan is a defined contribution plan for the benefit generally 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, as amended effective April 1, 1996, December 29, 1997 and January 1, 2001 are as follows: 5 2. Description of the Plan (continued) ----------------------------------- 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 amount is limited to $10,500. The Company contributes 3% of the employee's compensation for all participants in the Plan. In 2000 and 1999, the Company made profit sharing contributions to the Plan which were allocated to each participant's account based on the proportion of the participant's compensation to total compensation as defined. Participant Accounts -------------------- Each participant's account is credited with the participant's and the Company's contribution. Forfeitures are allocated on the last day of the Plan year on the same basis as Company profit sharing contributions. Vesting ------- Employee deferrals and the 3% Company contribution are 100% vested and non-forfeitable. Pre-January 2001 profit sharing company contribution balances vest as follows: 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. Allocation of Earnings or Losses of pre-January 1, 2001 Trust Fund ------------------------------------------------------------------ Assets ------ For the years ended December 31, 2000 and 1999, earnings or losses of Trust Fund assets were allocated to each participant's account in the ratio which the account balance had to the aggregate of all account balances as of the valuation date. 6 2. Description of the Plan (continued) ----------------------------------- Investment Options ------------------ For the year ended December 31, 2001, upon enrollment in the Plan, a participant may direct contributions in any of the following fourteen investment options. AIM International Equity Fund Alliance Premier Growth Fund Oppenheimer Discovery Fund PS Business Parks, Inc. Common Stock Public Storage, Inc. Common Stock Public Storage, Inc. Depository Shares Equity A Stock Smith Barney Fundamental Value Fund Smith Barney S&P 500 Index Smith Barney Small Cap Growth Opportunity Fund Van Kampen Growth and Income Fund Smith Barney U.S. Government Securities Fund Alliance Technology Fund Smith Barney Retirement Portfolio Van Kempen Emerging Growth Fund 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 up 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 Committee. 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 of the Plan as of December 31, 1983 may elect alternative distribution methods. 7 2. Description of the Plan (continued) ----------------------------------- Forfeitures ----------- The non-vested portion of a participant's account is forfeited as of the date of distribution of his/her vested interest. Employees resuming participation in the Plan prior to incurring the greater of five consecutive one-year breaks in service, or their prior service if greater than five years, may have the non-vested portion of their account balance restored upon repayment to the Plan of the full amount of such previously distributed vested interest. Restoration of the non-vested portion of a participant's account is to be made first from available forfeitures and then from Company contributions. 3. Investments ----------- All of the investments are under the custody of Salomon Smith Barney under a non-discretionary trust agreement with the Plan. Discretionary authority for the purchase and sale of plan assets is vested in the committee. The following table presents the fair value of investments. Investments that represent 5 percent or more of the Plan's net assets are separately identified. The fair value of investments is determined by quoted market price. The fair value of investments held by the Plan at December 31, 2001 and 2000 are summarized below: 2001 2000 ----------- ----------- Money Market Funds $3,124,526 $3,089,830 Mutual Funds 19,973,662 - Wells Fargo Collective Fund - 20,078,823 Equity Securities: Public Storage, Inc.

Plan Administration ------------------- The Committee appointed by the Company's Board of Directors administers the Plan. The Committee is now comprised of six officers and managers of the Company. Prior to 1988, the Company paid for all expenses (excluding investment advisory expenses) incurred for the administration of the Plan, although it was not obligated to do so under the terms of the Plan. Beginning in 1988, the Company's policy is to reimburse the Plan, at the Committee's discretion, for certain legal and administrative fees incurred for the administration of the Plan. For the plan year ended December 31, 1999, $51,038 of legal and administrative fees were reimbursed by the Company. None of these expenses were reimbursed during the plan years ended December 31, 2001and 2000. 5. Party-in-Interest Transactions ------------------------------ There were no party-in-interest transactions that are prohibited by ERISA Section 406 and for which no statutory or administrative exemption exists. 9 6. Benefits Owed To Terminated Participants ---------------------------------------- For financial reporting purposes disbursements to terminated participants are reported when the check is written. Approximately $3,200,000 and $1,745,000 were owed to terminated participants at December 31, 2001 and 2000, respectively. In addition, there were forfeited nonvested amounts of approximately $505,000 and $1,830,000 at December 31, 2001 and 2000, respectively. 10 SCHEDULE I ---------- PS 401(K)/PROFIT SHARING PLAN Schedule H, Line 4i - Assets held for investment purposes December 31, 2001 Employer Identification Number: 95-2782164 Plan Number: 001 Cost Fair Value ---- ----------- Money Market Account Smith Barney Retirement Portfolio * $3,124,526 Mutual Funds AIM International Equity Fund * 199,014 Alliance Premier Growth Fund * 548,379 Oppenheimer Discovery Fund * 161,650 Smith Barney Fundamental Value Fund * 1,192,993 Smith Barney S&P 500 Index * 12,170,926 Smith Barney Small Cap Growth Opportunity Fund * 328,526 Van Kampen Growth and Income Fund * 379,545 Smith Barney U.S. Government Securities Fund * 4,186,664 Alliance Technology Fund * 334,411 Van Kempen Emerging Growth Fund * 471,554 ----------- Total Mutual Funds 19,973,662 Equity Securities Public Storage, Inc.
