An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall Statement presentation. We believe that our audit provides a reasonable basis for our opinion. The accompanying Statement was prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission. In our opinion, the Statement presents fairly the combined certain revenues and certain operating expenses of the Prosperity Business Campus for the year ended December 31, 2000, in conformity with accounting principles generally accepted in the United States.

Background and Basis for Presentation The accompanying combined statements of certain revenues and certain operating expenses include the accounts of the Prosperity Business Campus located in Virginia and acquired by PS Business Parks, Inc., through its consolidated partnership (collectively referred to as the "Company") on June 1, 2001. The statements are prepared in order to comply with Rule 3.14 of Regulation S-X of the Securities and Exchange Commission. The combined statements of certain revenues and certain operating expenses include only the accounts and activities of the Prosperity Business Campus. Items that are not comparable to the future operations of the Prosperity Business Campus have been excluded. Such items include depreciation, amortization, management fees, interest income, professional fees, miscellaneous income and straight line rent adjustments. An audited statement is being presented for the most recent fiscal year available instead of the three most recent years based on the following factors: (i) the Prosperity Business Campus was acquired from a single unaffiliated party and (ii) based on the investigation of the Prosperity Business Campus by the Company, management is not aware of any material factors relating to the Prosperity Business Campus that would cause this financial information not to be necessarily indicative of future operating results other than the factors specifically considered by the Company as described below. In the decision to acquire the Prosperity Business Campus, the Company considered the competition from other commercial property owners, the location, the leases, the rental rates and the occupancy levels. The Company has reviewed the expenses of the Prosperity Business Campus, including salaries of on-site personnel, utilities, property taxes, supplies, insurance and repairs and maintenance. The Company expects that certain operating expenses in the future will be consistent with those reported for 2000 and the nine months ended September 30, 2001. 2. Summary of Significant Accounting Policies Revenue Recognition The Prosperity Business Campus leases space to tenants for which they charge minimum rents and receive reimbursement for certain operating expenses. The leases are accounted for as operating leases and are non-cancelable with varying terms and expiration dates. Recoveries from tenants are recognized as income in the period the applicable costs are accrued. Use of Estimates The preparation of the statements of certain revenues and certain operating expenses in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the statements of certain revenues and certain operating expenses and accompanying notes. Actual results could differ from those estimates. 6 REPORT OF INDEPENDENT AUDITORS To the Board of Directors of PS Business Parks, Inc.

During that period, the Company acquired 12 buildings known as the Prosperity Business Campus and 12 buildings known as the Cornell Oaks Corporate Center at an aggregate purchase price of approximately $175.9 million. The Company is not affiliated with the sellers and the purchase price was established through arm's length negotiations. The acquisitions were funded with the Company's existing cash balances and borrowings of $60 million from its unsecured line of credit with Wells Fargo Bank. In addition to adjustments to reflect the recently acquired properties, pro forma adjustments were made to reflect the following transactions: 1. On May 10, 2001 and June 18, 2001, the Company issued 1,840,000 and 800,000 depositary shares, respectively, each representing 1/1,000 of a share of the Company's 9 1/2% Cumulative Preferred Stock, Series D at $25.00 per share. Net proceeds were approximately $64.3 million and were used for investment in real estate. 2. On September 21, 2001, the Company completed a private placement of 2,120,000 preferred units with a preferred distribution rate of 9 1/4%. Net proceeds were approximately $51.6 million and were used for investment in real estate. The pro forma consolidated balance sheet at September 30, 2001 has been prepared to reflect the subsequent acquisitions of commercial properties. The pro forma consolidated statements of income for the nine months ended September 30, 2001 and the year ended December 31, 2000 have been prepared assuming (i) the aforementioned acquisitions of commercial properties and (ii) the aforementioned public offerings of depositary shares representing fractional interest in preferred stock and the private placement of preferred units, as if all such transactions were consummated at the beginning of the periods presented. The operations of all property acquisitions are based on historical operating results. The pro forma adjustments are based upon available information and upon certain assumptions as set forth in the notes to the pro forma consolidated financial statements that the Company believes is reasonable in the circumstances. The pro forma consolidated financial statements and accompanying notes should be read in conjunction with the historical financial statements of the Company and other documents filed with the Securities and Exchange Commission (such as Form 8-K's which reference property acquisitions) from time to time. The following pro forma consolidated financial statements do not purport to represent what the Company's results of operations would actually have been if the transactions had in fact occurred at the beginning of the dates indicated or to project the Company's results of operations for any future date or period. 10 PS BUSINESS PARKS, INC.
