To Brandywine Realty Trust
 
    We have audited the accompanying combined statement of revenue and certain
expenses of 3001-2-3 GREENTREE ASSOCIATES, L.P., 4000 AND 5000 GREENTREE
EXECUTIVE CAMPUS AND G.E.C. I & II MANAGEMENT CO., L.L.C. (the "GREENTREE
EXECUTIVE CAMPUS ACQUISITION PROPERTIES") described in Note 1 for the year ended
December 31, 1996. This combined financial statement is the responsibility of
management. Our responsibility is to express an opinion on this combined
financial 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 combined statement of revenue and certain
expenses is free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the combined
statement of revenue and certain expenses. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall presentation of the combined statement of revenue and
certain expenses. We believe that our audit provides a reasonable basis for our
opinion.
 
    The 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 for inclusion in a Current Report on Form 8K of Brandywine
Realty Trust as described in Note 1 and is not intended to be a complete
presentation of the GREENTREE EXECUTIVE CAMPUS ACQUISITION PROPERTIES' revenue
and expenses.
 
    In our opinion, the combined statement of revenue and certain expenses
referred to above presents fairly, in all material respects, the revenue and
certain expenses of the GREENTREE EXECUTIVE CAMPUS ACQUISITION PROPERTIES for
the year ended December 31, 1996, in conformity with generally accepted
accounting principles.

          NOTES TO COMBINED STATEMENT OF REVENUE AND CERTAIN EXPENSES
                               DECEMBER 31, 1996
 
NOTE 1: BASIS OF PRESENTATION
 
    The combined statement of revenue and certain expenses reflects the
operations of 3001-2-3 Greentree Associates, L.P., 4000 and 5000 Greentree
Executive Campus and G.E.C. I and II Management Co., L.L.C., (the Greentree
Executive Campus Acquisition Properties) located in Marlton, New Jersey. These
properties were acquired by Brandywine Realty Trust (the "Company") in April,
1997. The Greentree Executive Campus Acquisition Properties have an aggregate
net rentable area of approximately 156,000 square feet (95% leased as of
December 31, 1996). This combined statement of revenue and certain expenses is
to be included in the Company's Current Report on Form 8-K pursuant to the rules
and regulations of the Securities and Exchange Commission.
 
    The accounting records of Greentree Executive Campus Acquisition Properties
are maintained on a modified cash basis. Adjusting entries have been made to
present the accompanying financial statement in accordance with generally
accepted accounting principles. The accompanying financial statement excludes
certain expenses such as interest, depreciation and amortization, and other
costs not directly related to future operations of the Greentree Executive
Campus Acquisition Properties.
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts of assets and liabilities which affect the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from those estimates.
 
NOTE 2: OPERATING LEASE
 
    Base rents presented for the year ended December 31, 1996, do not include
straight-line adjustments for scheduled rent increases occurring over the lives
of the leases in accordance with generally accepted accounting principles
because the adjustment is considered immaterial.

responsibility of management. Our responsibility is to express an opinion on
this financial 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 financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting

assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
    The 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 for inclusion in the Current Report on Form 8-K of
Brandywine Realty Trust as described in Note 1 and is not intended to be a
complete presentation of 748 & 855 Springdale Drive's revenue and expenses.
 
    In our opinion, the financial statement referred to above presents fairly,
in all material respects, the revenue and certain expenses of 748 & 855
Springdale Drive for the year ended December 31, 1996, in conformity with

          NOTES TO COMBINED STATEMENTS OF REVENUE AND CERTAIN EXPENSES
                               DECEMBER 31, 1996
 
1. BASIS OF PRESENTATION:
 
    On June 5, 1997, Brandywine Operating Partnership, L.P. (the "Operating
Partnership"), a limited partnership of which Brandywine Realty Trust (the
"Company") is the sole general partner, acquired 748 & 855 Springdale Drive, a
portfolio of two office buildings located in West Whiteland Township,
Pennsylvania. 748 & 855 Springdale Drive contain an aggregate net rentable area
of approximately 64,594 square feet, which was 100% leased as of December 31,
1996. The net purchase price for 748 & 855 Springdale Drive was $5.3 million.
 
    The combined statements of revenue and certain expenses reflect the
operations of 748 & 855 Springdale Drive. These combined statements of revenue
and certain expenses are to be included in the Company's Current Report on Form
8-K as the acquisition has been deemed significant pursuant to the rules and
regulations of the Securities and Exchange Commission.
 
    The accounting records of 748 & 855 Springdale Drive are maintained on a
cash basis. Adjusting entries have been made to present the accompanying
financial statement in accordance with generally accepted accounting principles.
The accompanying financial statements exclude certain expenses such as interest,
depreciation and amortization, professional fees, and other costs not directly
related to the future operations of 748 & 855 Springdale Drive.
 
    The combined statements of revenue and certain expenses for the three months
ended March 31, 1997 and 1996, are unaudited. In the opinion of management, all
adjustments necessary to present fairly the revenue and certain expenses of 748
& 855 Springdale Drive for the three months ended March 31,1997 and 1996 have
been included. The combined revenue and certain expenses for such interim
periods are not necessarily indicative of the results for the full year.
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts of assets and liabilities which affect the
reported amounts of revenues and expenses during the reporting period. The
ultimate results could differ from those estimates.

principles. The aggregate rental revenue increase (decrease) resulting from the
straight-line adjustments for the year ended December 31, 1996, and the three
months ended March 31, 1997 and 1996, was ($1,000), ($3,000) (unaudited) and
($1,000,)
($3,000)(unaudited) and $1,000 (unaudited), respectively.

with expiration dates extending to the year 2001. Future minimum rentals 
under noncancelable operating leases, excluding tenant reimbursements of 
operating expenses as of December 31, 1996, are as follows:
