Brandywine Realty Trust Announces Fourth Quarter and Full Year 2007 Earnings and
Provides 2008 Earnings and FFO Guidance

Radnor, PA, February 20, 2008— Brandywine Realty Trust (NYSE:BDN), a real estate investment trust focused on the ownership, management and development of Class A, suburban and urban office properties in selected markets throughout the United States, announced today its financial and operating results for the three and twelve month periods ended December 31, 2007.

Financial Highlights

§	Funds from operations (FFO) totaled $53.5 million or $0.59 per diluted share in the fourth quarter of 2007, compared to $59.0 million or $0.63 per diluted share in the fourth quarter of 2006.

Net income in the fourth quarter of 2007 included a $40.5 million gain on the disposition of real estate related to the formation of our joint venture with DRA Advisors LLC and the $3.7 million hedge settlement expense, while net income in the fourth quarter of 2006 included an $11.6 million gain on the disposition of undepreciated real estate and a $15.1 million gain on the disposition of discontinued real estate.

FFO in 2007 included the $3.7 million ($0.04 per diluted share) hedge settlement expense. Our FFO payout ratio (common stock dividend divided by FFO per share) for 2007 was 69.0% versus 70.7% in 2006.
§	Net income totaled $48.5 million or $0.55 per diluted share for 2007, compared to $2.5 million or $0.03 per diluted share for 2006. Net income in 2007 included the $40.5 million gain on the disposition of real estate related to the formation of our joint venture with DRA Advisors, a $25.7 million gain on the disposition of discontinued real estate and the $3.7 million hedge settlement expense, while net income in 2006 included a $14.2 million gain on the disposition of undepreciated real estate, a $20.2 million gain on the disposition of discontinued real estate and a $3.1 million gain on the settlement of a purchase contract.

Portfolio Highlights

§	At December 31, 2007, our core portfolio was 93.9% occupied and 94.7% leased (reflecting leases commencing after December 31, 2007) versus 91.5% and 93.2%, respectively, at December 31, 2006. We owned 257 properties at December 31, 2007, encompassing 243 properties in our core portfolio and 14 properties under development or redevelopment.
§	In 2007, our net operating income (NOI) for our same store portfolio increased 1.1% on a GAAP basis and 1.6% on a cash basis for the 225 same store properties which were 93.5% occupied on December 31, 2007 versus 93.3% occupied on December 31, 2006. Our overall NOI margin on a GAAP basis was 61.3% for 2007 versus 61.4% for 2006.

§ For all of 2007, our core portfolio retention rate was 72.8% with positive net absorption of 294,805 square feet. In the fourth quarter of 2007, we achieved a 6.6% increase on our renewal rental rates and a 2.7% increase on our new lease rental rates, both on a GAAP basis.

Investment Highlights

§	We acquired no properties in the fourth quarter of 2007.
§	During the fourth quarter of 2007, we sold two office properties, 111/113 Pencader Drive in Newark, Delaware and 2490 Boulevard of the Generals in West Norriton, Pennsylvania, for $5.1 million and $1.5 million, respectively, and realized total gains on the sales of $0.3 million. As previously disclosed on December 20, 2007, we also completed the sale and contribution of a portfolio of 29 suburban Philadelphia office properties to a joint venture consisting of DRA Advisors LLC with an 80% interest and affiliates of Brandywine Realty Trust with a 20% interest. We sold the venture an 89% interest in three of the properties, and sold or contributed 100% interests in the rest. The overall portfolio was valued at $245.4 million (reflecting 100% interests throughout). In conjunction with the sale and contribution, we realized $230.9 million of net proceeds after deducting our transaction expenses, and recorded a gain on the sale and contribution of $40.5 million.
§	At December 31, 2007, we were actively proceeding on seven ground-up office developments and seven office redevelopments with a total identified cost of $718.3 million of which $442.6 million remained to be funded. These amounts include $375.0 million of costs for the combined 30th Street Post Office and garage development in Philadelphia, Pennsylvania of which $331.9 million remained to be funded at December 31, 2007, for the most part in 2009 and 2010. Since September 30, 2007, we have signed a series of new leases aggregating 301,487 square feet, bringing the total leasing rate to 57.5 % for our seven ground-up developments and to 69.4% for our seven redevelopments.

Capital Markets Highlights

§	During the fourth quarter of 2007, we closed and funded a $150.0 million, three-year unsecured term loan with a floating rate of LIBOR plus 80 basis points. The net proceeds were used to reduce indebtedness under our unsecured revolving credit facilities.
§	At December 31, 2007, our net debt to gross assets measured 53.6% compared to 52.0% at December 31, 2006 and 54.3% at September 30, 2007. At December 31, 2007, we had $475.7 million available for use and drawdown under our various credit facilities.
§	We achieved 2.5 times interest coverage ratio for the year ended December 31, 2007 versus 2.4 for the year ended December 31, 2006.

“Throughout the year, we have maintained consistently high levels of occupancy, retention and absorption in our core portfolio, while continuing to reduce the capital outlays to achieve these results,” stated Gerard H. Sweeney, President and CEO of Brandywine Realty Trust. “Our joint venture with DRA Advisors has established a good, alternative source of capital and we hope to increase our activities in this area as part of our overall capital recycling and balance sheet strengthening initiatives. We have also had some recent success in the lease-up of our development and redevelopment projects and will continue to push hard on that front. Our 2008 business and capital plans reflect a somewhat more cautious view on the economy, yet reinforce our commitment to maximizing total shareholder return. On a personal note, I want to thank Mike Prentiss and Tom August, our departing board trustees, for their fine service and contributions to Brandywine and wish them well in their future endeavors.”

Distributions

On December 11, 2007, our Board of Trustees declared a quarterly dividend distribution of $0.44 per common share that was paid on January 18, 2008 to shareholders of record as of January 4, 2008. Our Board also declared quarterly dividend distributions of $0.46875 per 7.50% Series C Cumulative Redeemable Preferred Share and $0.460938 per 7.375% Series D Cumulative Redeemable Preferred Share that were paid on January 15, 2008 to holders of record as of December 30, 2007 of the Series C and Series D Preferred Shares, respectively.

Share Repurchase Program

We are authorized to purchase an additional 539,200 common shares and may make repurchases from time to time in the open market or in privately negotiated transactions, subject to market conditions and compliance with legal requirements. The share repurchase program does not contain any time limitation and does not obligate us to repurchase any shares. We did not purchase any shares in the fourth quarter of 2007 or to date in 2008 and may discontinue the program at any time.

2008 Earnings and FFO Guidance

Based on current plans and assumptions and subject to the risks and uncertainties more fully described in Brandywine’s reports filed with the Securities and Exchange Commission, we are introducing FFO guidance for full year 2008 to be in a range of $2.46 to $2.56 per diluted share. This guidance is provided for informational purposes and is subject to change. The following is a reconciliation of the calculation of FFO per diluted share and earnings per diluted share:

Guidance for 2008	Range or Value
Earnings per diluted share allocated to common shareholders	$	0.06	to	$	0.16
Plus: real estate depreciation and amortization		2.40			2.40
FFO per diluted share	$	2.46	to	$	2.56

Key assumptions in our guidance range include same store NOI growth (GAAP) of 0.5%-1.0% incorporating a 100 basis point increase in occupancy by year-end 2008, flat to slightly higher operating expenses/real estate taxes, a 3.0%-5.0% mark-to-market on our new lease rental rates and a 3.0%-4.5% mark-to-market on our renewal rental rates. We are assuming general and administrative expenses of $25.0-$27.0 million and interest expenses (net of capitalized interest for development activity) and deferred financing fees of $153.0-$160.0 million. For 2008, we are projecting approximately $2.5-$3.0 million of incremental NOI from five key ground-up developments — South Lake, 2100 Franklin, Barton Creek, Metroplex I and 1200 Lenox Drive — and are targeting year-end occupancy for this group to be in a range of 30.0%-35.0%. For other income categories including termination fees, management income, interest income, income from joint ventures and certain other items, we are targeting a range of $30.0-$38.0 million compared to $47.0 million in 2007. Lastly, our 2008 projections reflect aggregate sale activity of $155.0-$162.0 million at a 7.5%-8.0% capitalization rate, no acquisitions, no new development starts and no stock buyback activity.

For guidance purposes, we have not considered any future gains from the sale of real estate not previously disclosed. Our 2008 FFO guidance does not include any income from the sale of undepreciated real estate, in accordance with our current practice.

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 our and our affiliates’ actual results, performance, achievements or transactions to be materially different

- 3 -

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: our 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, equity or other financing; competition for real estate acquisitions; risks of acquisitions, dispositions and developments, including the cost of construction delays and cost overruns; unanticipated operating and capital costs; our 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 our tenants operate. Additional information on factors which could impact us and the forward-looking statements contained herein are included in our filings with the Securities and Exchange Commission, including our Annual Report for the year ended December 31, 2006. We assume no obligation to update or supplement forward-looking statements that become untrue because of subsequent events except as required by law.

Non-GAAP Supplemental Financial Measures

We compute our financial results in accordance with generally accepted accounting principles (GAAP). Although FFO, NOI and CAD are non-GAAP financial measures, we believe that FFO, NOI and CAD calculations are helpful to shareholders and potential investors and are widely recognized measures of real estate investment trust performance. At the end of this press release, we have provided a reconciliation of the non-GAAP financial measures to the most directly comparable GAAP measure.

Funds from Operations (FFO)

We compute 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 us. NAREIT defines FFO as net income (loss) before minority interest of unit holders (preferred and common) and excluding gains (losses) on sales of property and extraordinary items (computed in accordance with GAAP); plus real estate related depreciation and amortization (excluding amortization of deferred financing costs), and after similar adjustments for unconsolidated joint ventures. Net income, the GAAP measure that we believe to be most directly comparable to FFO, includes depreciation and amortization expenses, gains or losses on property sales, extraordinary items and minority interest. To facilitate a clear understanding of our 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 flow from operating activities (determined 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 our financial performance or to be an alternative to cash flow from operating activities (determined in accordance with GAAP) as a measure of our liquidity, nor is it indicative of funds available for our cash needs, including our ability to make cash distributions to shareholders.

For information purposes, we may provide FFO adjusted for debt extinguishment costs. Although our calculation of FFO as adjusted differs from NAREIT’s definition of FFO, and may not be comparable to that of other REITs and real estate companies, we believe it provides a meaningful supplemental measure of our operating performance because we believe that by excluding the effects of debt extinguishment, shareholders and potential investors are presented with an indicator of our operating performance that more closely achieves the objectives of the real estate industry in presenting FFO.

Net Operating Income (NOI)

NOI is a non-GAAP financial measure equal to net income available to common shareholders, the most directly comparable GAAP financial measure, plus corporate general and administrative expense, depreciation and amortization, interest expense, minority interest in the Operating Partnership and losses from early extinguishment of debt, less interest income, development and management income, gains from property

- 4 -

dispositions, gains on sale from discontinued operations, income from discontinued operations, income from unconsolidated joint ventures and minority interest in property partnerships. In some cases, we also present NOI on a cash basis, which is NOI after eliminating the effect of straight-lining of rent and deferred market intangible amortization. NOI presented by us may not be comparable to NOI reported by other REITs that define NOI differently. NOI should not be considered an alternative to net income as an indication of our performance, or as an alternative to cash flow from operating activities as a measure of our liquidity or ability to make cash distributions to shareholders.

Cash Available for Distribution (CAD)

CAD is a non-GAAP financial measure that is not intended as an alternative to cash flow from operating activities as determined under GAAP. CAD is presented solely as a supplemental disclosure with respect to liquidity because we believe it provides useful information regarding our ability to fund our distributions. Because other companies do not necessarily calculate CAD the same way as we do, our presentation of CAD may not be comparable to similarly titled measures provided by other companies.

Fourth Quarter Earnings Call and Supplemental Information Package

We will host a conference call on Thursday, February 21, 2008 at 11:00 a.m. EST. The conference call can be accessed by calling 1-800-683-1525 and referencing conference ID #30236098.
