                        CORPORATE OFFICE PROPERTIES TRUST
             PRO FORMA CONDENSED CONSOLIDATING FINANCIAL INFORMATION

The following sets forth the unaudited pro forma condensed consolidating balance
sheet of Corporate Office Properties Trust and its consolidated affiliates,
including Corporate Office Properties, L.P. (the "Operating Partnership") as of
September 30, 1998, and the unaudited pro forma condensed consolidating
statements of operations for the year ended December 31, 1997 and the nine month
period ended September 30, 1998, of the Company (as defined below). Corporate
Office Properties Trust and its consolidated affiliates, including the Operating
Partnership, are collectively referred to herein as the "Company."

In October 1997, the Operating Partnership acquired partnership interests in a
portfolio of ten properties (the "Initial Office Properties"), representing the
Mid-Atlantic suburban office operations of The Shidler Group, subject to $100
million of indebtedness (the "Term Credit Facility"). At that time, the Company
became the sole general partner of the Operating Partnership, which was formed
to acquire and hold the Initial Office Properties. In connection with the
acquisition of the Initial Office Properties, the Company issued 600,000 of its
common shares of beneficial interest ("Common Shares") and the Operating
Partnership issued (or committed to issue) 3,181,818 common partnership units
("Common Units") and 2.1 million preferred partnership units ("Preferred Units"
or "Preferred 1997 Units").

The acquisition of the Initial Office Properties is reflected in the Company's
historical consolidated balance sheet as of September 30, 1998, and is included
in the pro forma condensed consolidating statements of operations as if it
occurred on January 1, 1997.

The pro forma condensed consolidating financial information is presented as if
the following transactions had been consummated on the earlier of the actual
date of consummation or September 30, 1998, for balance sheet purposes, and at
January 1, 1997, for purposes of the statements of operations:

- -     The consummation of a public offering (the "Offering") on April 27, 1998,
      in which the Company issued 7,500,000 Common Shares at $10.50 per share

      exchange for 7,500,000 Common Units.

      buildings (the "Airport Square Properties") on April 30, 1998.

      consideration for the Fairfield Properties.

- -     The acquisition by the Company on September 28, 1998, from various parties

                        REPORT OF INDEPENDENT ACCOUNTANTS

                                     -------



January 18, 1999

To Corporate Office Properties Trust:

We have audited the accompanying combined statement of revenue and certain
expenses of the Gateway Properties (the "Properties") as described in Note 1 for
the year ended December 31, 1997. This historical statement is the
responsibility of the Properties' management. Our responsibility is to express
an opinion on this historical statement based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the historical statement is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the historical statement. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall presentation of the historical
statement. We believe that our audit provides a reasonable basis for our
opinion.

The accompanying combined statement of revenue and certain expenses was prepared
for the purpose of complying with the rules and regulations of the Securities
and Exchange Commission as described in Note 2, and is not intended to be a
complete presentation of the Properties' revenues and expenses.

In our opinion, the historical statement referred to above presents fairly, in
all material respects, the combined revenues and certain expenses as described
in Note 2 of the Gateway Properties for the year ended December 31, 1997, in
conformity with generally accepted accounting principles.

          NOTES TO COMBINED STATEMENT OF REVENUE AND CERTAIN EXPENSES

                                    -------

1.    BUSINESS:

      The accompanying combined statement of revenue and certain expenses
      relates to the operation of Gateway Properties (the "Properties"),
      consisting of the revenues and certain expenses of three buildings located
      at 6716, 6740 and 6760 Alexander Graham Bell Drive, which contains 149,394
      total square feet.


2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

      BASIS OF PRESENTATION:

      The accompanying combined statement of revenue and certain expenses was
      prepared for the purpose of complying with the rules and regulations of
      the Securities and Exchange Commission. The statement is not
      representative of the actual operations of the Properties for the period
      presented nor indicative of future operations as certain expenses,
      primarily depreciation, amortization, interest expense and ground rent,
      which may not be comparable to the expenses expected to be incurred by
      Corporate Office Properties Trust in future operations of the Properties,
      have been excluded.

      REVENUE AND EXPENSE RECOGNITION:

      Revenue is recognized on a straight-line basis over the terms of the
      related lease. Expenses are recognized in the period in which they are
      incurred.

      USE OF ESTIMATES:

      The preparation of this historical statement in conformity with generally
      accepted accounting principles requires management to make estimates and
      assumptions that affect the reported amounts of revenue and expenses
      during the reporting period. Actual results could differ from these
      estimates.

      MAJOR TENANT:

      During 1997, the Properties' rental revenue included rental income from
      three major tenants that comprised approximately 55% of total combined
      rental revenue.

3.    RENTALS:

      The Properties have entered into non-cancelable tenant leases, with
      expiration dates ranging from 1998 to 2002, that provide for the tenants
      to share in the operating and real estate taxes on a prorata basis, as
      defined in the leases. Future minimum rentals to be received under these
      tenant leases are as follows:
