CANYON PARK COMMONS Notes to Historical Summaries of Operating Revenue and Expenses For the nine months ended September 30, 1997 (unaudited) and the year ended December 31, 1996 (dollars in thousands) (1) Description of the Property Canyon Park Commons (the Building) consists of one building located in Bothell, Washington, a submarket of Seattle, containing approximately 95,000 square feet of office space available for lease. As of September 30, 1997, the building was 100% leased to one tenant. (2) Summary of Significant Accounting Policies (a) Basis of Presentation The accompanying historical summaries of operating revenue and expenses are not representative of the actual operations for the periods presented, as certain revenue and expenses, which may not be comparable to those expected to be incurred by CarrAmerica Realty Limited Partnership in the proposed future operations of the Building, have been excluded. Interest income has been excluded from revenue, and interest, depreciation and amortization, and other costs not directly related to the future operations of the Building have been excluded from expenses. Management is not aware of any other material factors that would cause the historical summaries of operating revenue and expenses to not be indicative of the future operating results of the Building. (b) Revenue Recognition Revenue from rental operations is recognized straight-line over the terms of the respective leases. (c) Interim Unaudited Financial Information The accompanying unaudited financial information for the nine months ended September 30, 1997 has been prepared consistent with the rules and regulations of the Securities and Exchange Commission governing the preparation of the amounts for the year ended December 31, 1996. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations, although management believes that the disclosures are adequate to make the information presented not misleading. In the opinion of management, all adjustments, consisting only of normal recurring accruals, necessary to present fairly the historical summary of operating revenue and expenses for the nine months ended September 30, 1997, have been included. The results of operations for the nine-month period ended September 30, 1997 are not necessarily indicative of the results for the full year.

For purposes of presenting pro forma net taxable operating income, revenue is recognized when it is either collectible under the lease terms or collected. Tax depreciation for the buildings is computed on the modified accelerated cost recovery system method over a 39-year life. This statement does not purport to forecast actual operating results for any period in the future.
