          Brandywine Realty Trust Announces First Quarter 2003 Earnings

PLYMOUTH MEETING, PA, April 24, 2003 - Brandywine Realty Trust (BDN-NYSE)
announced today that fully diluted earnings per share (EPS) were $.30 for the
first quarter of 2003, a decrease of $.25 per share as compared to $.55 for the
first quarter of 2002. Net income was $13.9 million for the first quarter of
2003, a decrease of $9.6 million, as compared to $23.5 million for the first
quarter of 2002. The decrease in net income and EPS in the first quarter of 2003
as compared to the similar period in 2002 was primarily due to the net gain on
disposition of discontinued operations of $.6 million in 2003 as compared to
$8.4 million in 2002.

Fully diluted funds from operations (FFO) were $30.1 million or $.65 per share
for the first quarter 2003 compared to $32.4 million or $0.68 per share for the
first quarter of 2002. FFO represents a non generally accepted accounting
principle ("GAAP") financial measure. A table reconciling FFO to net income, the
GAAP measure that the Company believes to be most directly comparable, is within
the consolidated financial statements included in this release.

 "We executed very well against our first quarter 2003 business plan in what
continues to remain a challenging leasing environment. Our occupancy at the end
of the quarter slightly exceeded our expectations. Our financial results,
particularly on a same store basis, were impacted by excessive snow removal
expenses. We continue to achieve high tenant retention and remain focused on our
tenant service platform. As expected, capital costs and lease rates remain under
pressure, however, our first quarter statistics were directly in line with our
business plan goals. Overall, we remain encouraged by our transaction flow and
the strength of our market position," commented Gerard H. Sweeney, Brandywine's
President and Chief Executive Officer.

Distributions

On March 25, 2003, the Board of Trustees declared a regular quarterly dividend
distribution of $0.44 per common share that was paid on April 15, 2003 to
shareholders of record as of April 4, 2003.

2003 Financial Outlook

As a result of economic conditions in the Company's markets, we continue to
experience challenging operational conditions resulting in difficult earnings
visibility. Our expectations for 2003 are based on the following key
assumptions:

o  Occupancy is expected to decline slightly from the levels achieved in 2002.
o  Same-store net operating income is expected to decrease in the range of 1.5%
   to 3.0%.
o  Operating expenses (excluding snow removal) and real estate taxes and general
   and administrative expenses as a percentage of revenues are expected to be
   consistent with those experienced in 2002.

Based on these key assumptions and management's view of current and anticipated
market conditions, we affirm our guidance from our February 27, 2003 press
release and continue to expect the second quarter 2003 EPS to be $.26 - $.29 per
share and FFO to be $.65 - $.67 per share and full year 2003 EPS to be $1.11 to
$1.17 and FFO to be $2.62 - $2.69 per share.

Forward-Looking Statements

Estimates of future earnings per share and FFO per share and certain other
statements in this release constitute "forward-looking statements" within the
meaning of the Private Securities Litigation Reform Act of 1995. Such
forward-looking statements involve known and unknown risks, uncertainties and
other factors that may cause the actual results, performance, achievements or
transactions of the Company and its affiliates to be materially different from
any future results, performance, achievements or transactions expressed or
implied by such forward-looking statements. Such risks, uncertainties and other
factors relate to, among others: the Company's ability to lease vacant space and
to renew or relet space under expiring leases at expected levels, competition
with other real estate companies for tenants, the potential loss or bankruptcy
of major tenants, interest rate levels, the availability of debt and equity
financing, competition for real estate acquisitions and risks of acquisitions,
dispositions and developments, including the cost of construction delays and
cost overruns, unanticipated operating and capital costs, the Company's ability
to obtain adequate insurance, including coverage for terrorist acts, dependence
upon certain geographic markets, and general and local economic and real estate
conditions, including the extent and duration of adverse changes that affect the
industries in which the Company's tenants compete. Additional information on
factors which could impact the Company and the forward-looking statements
contained herein are included in the Company's filings with the Securities and
Exchange Commission, including the Company's Annual Reports on Form 10-K. The
Company assumes no obligation to update or supplement forward-looking statements
that become untrue because of subsequent events.

Non-GAAP Supplemental Financial Measures

Funds from Operations (FFO)
- ---------------------------
FFO is a widely recognized measure of REIT performance. Although FFO is a
non-GAAP financial measure, the Company believes that information regarding FFO
is helpful to shareholders and potential investors. The Company computes FFO in
accordance with standards established by the National Association of Real Estate
Investment Trusts (NAREIT), which may not be comparable to FFO reported by other
REITs that do not compute FFO in accordance with the NAREIT definition, or that
interpret the NAREIT definition differently than the Company. NAREIT defines FFO
as net income (loss) before minority interest of unitholders (preferred and
common) and excluding gains (losses) on sales of depreciable operating property
and extraordinary items (computed in accordance with GAAP); plus real estate
related depreciation and amortization (excluding amortization of deferred
financing costs), and after adjustment for unconsolidated joint ventures. The
GAAP measure that the Company believes to be most directly comparable to FFO,
net income, includes depreciation and amortization expenses, gains or losses on






property sales and minority interest. In computing FFO, the Company eliminates
substantially all of these items because, in the Company's view, they are not
indicative of the results from the Company's property operations. To facilitate
a clear understanding of the Company's historical operating results, FFO should
be examined in conjunction with net income (determined in accordance with GAAP)
as presented in the financial statements included elsewhere in this release. FFO
does not represent cash generated from operating activities in accordance with
GAAP and should not be considered to be an alternative to net income (loss)
(determined in accordance with GAAP) as an indication of the Company's financial
performance or to be an alternative to cash flow from operating activities
(determined in accordance with GAAP) as a measure of the Company's liquidity,
nor is it indicative of funds available for the Company's cash needs, including
its ability to make cash distributions to shareholders.

Cash Available for Distribution (CAD)
- -------------------------------------
Cash available for distribution, CAD, is a non-GAAP financial measure that is
not intended to represent cash flow for the period and is not indicative of cash
flow provided by operating activities as determined under GAAP. CAD is presented
solely as a supplemental disclosure with respect to liquidity because the
Company believes it provides useful information regarding the Company's ability
to fund its dividends. Because all companies do not calculate CAD the same way,
the presentation of CAD may not be comparable to similarly titled measures of
other companies.
