As of June 30, 2006, the Company owned 278 office properties, 23 industrial facilities and 1 mixed-use property (collectively, the “Properties”) containing an aggregate of approximately 30.3 million net rentable square feet. As of June 30, 2006, the Company owned economic interests in eleven unconsolidated real estate ventures that contain approximately 2.7 million net rentable square feet (the “Real Estate Ventures”) and in four consolidated real estate ventures that own 16 office properties containing approximately 1.6 million net rentable square feet. The Properties and the properties owned by the Real Estate Ventures are located in or areas surrounding Philadelphia, Pennsylvania; Wilmington, Delaware; Austin, Texas; Dallas, Texas; Richmond, Virginia; Northern and Southern California; Southern and Central New Jersey and Northern Virginia.

As more fully described in Note 3, on January 5, 2006, the Company acquired Prentiss Properties Trust (“Prentiss”) under an Agreement and Plan of Merger (the “Merger Agreement”) that the Company entered into with Prentiss on October 3, 2005.

The Company owns its assets through Brandywine Operating Partnership, L.P. a Delaware limited partnership (the “Operating Partnership”). The Company is the sole general partner of the Operating Partnership and, as of June 30, 2006, owned a 95.7% interest in the Operating Partnership.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements have been prepared by the Company without audit except as to the balance sheet as of December 31, 2005, which has been derived from audited data, pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the included disclosures are adequate to make the information presented not misleading. In the opinion of management, all adjustments (consisting solely of normal recurring matters) for a fair statement of the financial position of the Company as of June 30, 2006, the results of its operations for the three- and six-month periods ended June 30, 2006 and 2005 and its cash flows for the six-month periods ended June 30, 2006 and 2005 have been included. The results of operations for such interim periods are not necessarily indicative of the results for a full year. These consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and footnotes included in the Company’s 2005 Annual Report on Form 10-K. Certain prior period amounts have been reclassified to conform to the current period presentation.

BRANDYWINE REALTY TRUST

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

June 30, 2006

Principles of Consolidation

The accompanying consolidated financial statements include all accounts of the Company, and its majority-owned and/or controlled subsidiaries. The portion of these entities not owned by the Company is presented as minority interest as of and during the periods consolidated. All intercompany accounts and transactions have been eliminated in consolidation.

When the Company obtains an economic interest in an entity, the Company evaluates the entity to determine if the entity is deemed a variable interest entity (“VIE”), and if the Company is deemed to be the primary beneficiary, in accordance with FASB Interpretation No. 46R, “Consolidation of Variable Interest Entities” (“FIN 46R”). The Company consolidates (i) entities that are VIEs where the Company is deemed to be the primary beneficiary and (ii) entities that are non-VIEs which the Company controls. Entities that the Company accounts for under the equity method (i.e., at cost, increased or decreased by the Company’s share of earnings or losses, less distributions) include (i) entities that are VIEs where the Company is not deemed to be the primary beneficiary and (ii) entities that are non-VIEs which the Company does not control, but over which the Company has the ability to exercise significant influence. The Company will reconsider its determination of whether an entity is a VIE and who the primary beneficiary is if certain events occur that are likely to cause a change in the original determinations.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Management makes significant estimates regarding revenue, impairment of long-lived assets, allowance for doubtful accounts and deferred costs.

Operating Properties

Operating properties are carried at historical cost less accumulated depreciation and impairment losses. The cost of operating properties reflects their purchase price or development cost. Costs incurred for the acquisition and renovation of an operating property are capitalized to the Company’s investment in that property. Ordinary repairs and maintenance are expensed as incurred. Major replacements and betterments, which improve or extend the life of the asset, are capitalized and depreciated over their estimated useful lives. Fully-depreciated assets are removed from the accounts.

SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, required us to separately report as discontinued operations the historical operating results attributable to operating properties sold or held for sale and the applicable gain or loss on the disposition of the properties. The consolidated statements of operations for prior periods are also adjusted to conform to this classification. In all cases, gains and losses are recognized using the full accrual method of accounting. Gains relating to transactions which do not meet the requirements of the full accrual method of accounting are deferred and recognized when the full accrual method of accounting criteria are met.

Purchase Price Allocation

The Company allocates the purchase price of properties to net tangible and identified intangible assets acquired based on fair values. Above-market and below-market in-place lease values for acquired properties are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) the Company’s estimate of the fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease. Capitalized above-market lease values are amortized as a reduction of rental income over the remaining non-cancelable terms of the respective leases. Capitalized below-market lease values are amortized as an increase to rental income over the remaining non-cancelable terms of the respective leases, including any fixed-rate renewal periods.

Other intangible assets also include amounts representing the value of tenant relationships and in-place leases based on

BRANDYWINE REALTY TRUST

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

June 30, 2006

the Company’s evaluation of the specific characteristics of each tenant’s lease and the Company’s overall relationship with the respective tenant. The Company estimates the cost to execute leases with terms similar to the remaining lease terms of the in-place leases, including leasing commissions, legal and other related expenses. This intangible asset is amortized to expense over the remaining term of the respective leases. Company estimates of value are made using methods similar to those used by independent appraisers or by using independent appraisals. Factors considered by the Company in this analysis include an estimate of the carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases. The Company also considers information obtained about each property as a result of its pre-acquisition due diligence, marketing and leasing activities in estimating the fair value of the tangible and intangible assets acquired. The Company also uses the information obtained as a result of its pre-acquisition due diligence as part of its consideration of FIN47, and when necessary, will record a conditional asset retirement obligation as part of its purchase price. In estimating carrying costs, the Company includes real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods, which primarily range from three to twelve months.

Characteristics considered by the Company in allocating value to its tenant relationships include the nature and extent of the Company’s business relationship with the tenant, growth prospects for developing new business with the tenant, the tenant’s credit quality and expectations of lease renewals, among other factors. The value of tenant relationship intangibles is amortized over the remaining initial lease term and expected renewals, but in no event longer than the remaining depreciable life of the building. The value of in-place leases is amortized over the remaining non-cancelable term of the respective leases and any fixed-rate renewal periods.

In the event that a tenant terminates its lease, the unamortized portion of each intangible, including market rate adjustments, in-place lease values and tenant relationship values, would be charged to expense.

Revenue Recognition and Accounts Receivable

Rental revenue is recognized on the straight-line basis from the later of the date of the commencement of the lease or the date of acquisition of the property subject to existing leases, which averages minimum rents over the terms of the leases. The cumulative difference between lease revenue recognized under this method and contractual lease payment terms is recorded as “accrued rent receivable” on the accompanying balance sheets. The straight-line rent adjustment increased revenue by approximately $8.1 million and $15.6 million for the three- and six-month periods ended June 30, 2006 and approximately $3.1 million and $6.3 million for the three- and six-month periods ended June 30, 2005. Tenant receivables and accrued rent receivables are carried net of the allowances for doubtful accounts of $7.8 million as of June 30, 2006 and $4.9 million as of December 31, 2005. The allowance is based on management’s evaluation of the collectability of receivables, taking into account tenant specific considerations as well as the overall credit of the tenant portfolio. The leases also typically provide for tenant reimbursement of a portion of common area maintenance and other operating expenses. Other income is recorded when earned and is primarily comprised of termination fees received from tenants, bankruptcy settlement fees, third party leasing commissions, and third party management fees. Other income includes net termination fees of $1.3 million and $1.9 million for the three- and six-month periods ended June 30, 2006, and $0.9 million and $4.9 million for the three- and six-month periods ended June 30, 2005. Deferred rents represent rental revenue received from tenants prior to their due dates.

Stock-based Compensation Plans

The Company maintains shareholder-approved equity incentive plans. The Compensation Committee of the Company’s Board of Trustees authorizes awards under these plans. In May 2005, the Company’s shareholders approved an amendment to the Amended and Restated 1997 Long-Term Incentive Plan (the “1997 Plan”) that increased the number of common shares that may be issued or subject to award under the 1997 Plan from 5,000,000 to 6,600,000. The May 2005 amendment provided that 500,000 of the shares under the 1997 Plan are available solely for awards under options and share appreciation rights that have an exercise or strike price not less than the market price of the common shares on the date of award, and the remaining 6,100,000 shares are available for any type of award under the 1997 Plan. Incentive stock options may not be granted at exercise prices less than fair value of the shares at the time of grant. All options awarded by the Company to date are non-qualified stock options that generally vested over two to five years. As of June 30, 2006, 2.6 million shares remained available for future award under the 1997 Plan. As part of the Company’s January 2006 acquisition of Prentiss, the Company assumed Prentiss’ three share incentive

plans. As of June 30, 2006, approximately 1,685,676 common shares remain available for issuance or subject to award under the assumed Prentiss share incentive plans; however, any such issuances or awards under the assumed Prentiss plan may be made only to those Company employees who had been employed by Prentiss immediately prior to the Company’s acquisition of Prentiss or to those Company employees hired after the Prentiss acquisition.

On January 1, 2002, the Company began to expense the fair value of stock-based compensation awards granted subsequent to January 1, 2002, over the applicable vesting period as a component of general and administrative expenses in the Company s consolidated statements of income. In the three and six-month periods ended June 30, 2006 the Company recognized $669,000 and $1,445,000 of stock-based compensation expense. In the three and six-month periods ended June 30, 2005 the Company recognized and $696,000 and $1,387,000 of stock-based compensation expense.

For stock-based compensation awards granted prior to 2002, the Company accounted for stock options issued under the recognition and measurement provisions of APB No.25, Accounting for Stock Issued to Employees and Related Interpretations. Under this method, no stock-based compensation expense was recognized. Because stock options granted prior to 2002 vested over a three-year term, the resulting compensation cost based on the fair value of the awards on the date of grant, on a pro forma basis would have been expensed in 2003, 2004, and 2005. Accordingly, had the Company applied the fair value recognition provisions of SFAS 123, the net income applicable to common shares would remain the same on a pro forma basis for the three and six month periods ended June 30, 2006, and would have been reduced by $117,000 and $256,000 for the three and six month periods ended June 30, 2005, with no change in basic or diluted net income per share.

The Company’s primary form of share-based compensation has been restricted shares issued under a shareholder approved equity incentive plan that authorizes various equity-based awards. As of June 30, 2006, 352,036 restricted shares were outstanding and vest over five years from the initial grant date. The remaining compensation expense to be recognized associated with the 352,036 restricted shares outstanding at June 30, 2006 was approximately $9.9 million. That expense is expected to be recognized over a weighted average remaining vesting period of 1.9 years. For the three month and six month periods ended June 30, 2006, the Company recognized $669,000 and $1,445,000 of compensation expense related to outstanding restricted shares. The following table summarizes the Company’s restricted share activity for the six-months ended June 30, 2006:

	Shares		Weighted Average Grant Date Fair value

Non-vested at January 1, 2006	316,134		$	25.62

Forfeited	(43,640	)		28.32

Non-vested at June 30, 2006	352,036		$	28.24

At June 30, 2006, the Company had 1,412,300 options outstanding under its shareholder approved equity incentive plan. No options were unvested as of June 30, 2006 and therefore there is no remaining unrecognized compensation expense associated with these options. Option activity as of June 30, 2006 and changes during the six months ended June 30, 2006 were as follows:

The Company has the ability and intent to issue shares upon stock option exercises. Historically, the Company has issued new common shares to satisfy such exercises.

Accounting for Derivative Instruments and Hedging Activities

The Company accounts for its derivative instruments and hedging activities under SFAS No. 133 (“SFAS 133”), Accounting for Derivative Instruments and Hedging Activities, and its corresponding amendments under SFAS No. 138, Accounting for Certain Derivative Instruments and Hedging Activities – An Amendment of SFAS 133. SFAS 133 requires the Company to measure every derivative instrument (including certain derivative instruments embedded in other contracts) at fair value and record them in the balance sheet as either an asset or liability. For derivatives designated as fair value hedges, the changes in fair value of both the derivative instrument and the hedged item are recorded in earnings. For derivatives designated as cash flow hedges, the effective portions of changes in the fair value of the derivative are reported in other comprehensive income. Changes in fair value of derivative instruments and ineffective portions of hedges are recognized in earnings in the current period. For the three- and six-month periods ended June 30, 2006 and 2005, the Company was not party to any derivative contract designated as a fair value hedge.

The Company actively manages its ratio of fixed-to-floating rate debt. To manage its fixed and floating rate debt in a cost-effective manner, the Company, from time to time, enters into interest rate swap agreements as cash flow hedges, under which it agrees to exchange various combinations of fixed and/or variable interest rates based on agreed upon notional amounts.

Income Taxes

The Company and a subsidiary REIT elect to be taxed as real estate investment trusts under Sections 856-860 of the Internal Revenue Code. In order to maintain its qualification as a REIT, the Company is required, among other things, to distribute at least 90% of its REIT taxable income to its shareholders and meet certain tests regarding the nature of its income and assets. As a REIT, the Company is not subject to federal income tax with respect to that portion of its income which meets certain criteria and is distributed annually to the shareholders. Accordingly, no provision for federal income taxes is included in the accompanying consolidated financial statements. The Company plans to continue to operate so that it meets the requirements for taxation as a REIT. Many of these requirements, however, are highly technical and complex. If the Company were to fail to meet these requirements, the Company would be subject to federal income tax. The Company is subject to certain state and local taxes. Provision for such taxes has been included in general and administrative expenses in the Company’s consolidated statements of operations.

Recent Accounting Pronouncements

In June 2006, the FASB issued Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109 (“FIN 48”). FIN 48 clarifies the accounting for uncertainty in income taxes recognized in a company’s financial statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 also provides guidance on description, classification, interest and penalties, accounting in interim periods, disclosure and transition. FIN 48 becomes effective on January 1, 2007. The Company is currently evaluating the impact of adopting FIN 48 but does not expect it to have a material impact on the consolidated financial statements.

In March 2006, the FASB issued SFAS No. 156, Accounting for Servicing of Financial Assets, an Amendment of SFAS No. 140. SFAS No. 156 requires separate recognition of a servicing asset and a servicing liability each time an entity undertakes an obligation to service a financial asset by entering into a service contract. This statement also requires that servicing assets and liabilities be initially recorded at fair value and subsequently adjusted to the fair value at the end of each reporting period. This statement is effective in fiscal years beginning after September 15, 2006. The Company does not expect the adoption of this standard on January 1, 2007 to have a material effect on the consolidated financial statements.

In February 2006, the FASB issued SFAS No.155, Accounting for Certain Hybrid Financial Instruments – An Amendment of FASB No. 133 and 140. The purpose of SFAS No.155 is to simplify the accounting for certain hybrid financial instruments by permitting fair value re-measurement for any hybrid financial instrument that contains an embedded derivative that otherwise would require bifurcation. SFAS No. 155 also eliminates the restriction on passive derivative instruments that a qualifying special-purpose entity may hold. SFAS No. 155 is effective for all financial instruments acquired or issued after the beginning of an entity’s first fiscal year beginning after September 15, 2006. The Company does not expect the adoption of this standard on January 1, 2007 to have a material effect on the consolidated financial statements.

In October 2005, the FASB issued Staff Position No. 13-1 “Accounting for Rental Costs Incurred during a Construction Period” (“FSP FAS 13-1”). FSP FAS 13-1 addresses the accounting for rental costs associated with operating leases that are incurred during the construction period. FSP FAS 13-1 makes no distinction between the right to use a leased asset during the construction period and the right to use that asset after the construction period. Therefore, rental costs associated with ground or building operating leases that are incurred during a construction period shall be recognized as rental expense, allocated over the lease term in accordance with SFAS No. 13 and Technical Bulletin 85-3. The terms of FSP FAS 13-1 are not applicable to lessees that account for the sale or rental of real estate projects in accordance with SFAS No. 67, “Accounting for Costs and Initial Rental Operations of Real Estate Projects.” FSP FAS 13-1 was effective for the first reporting period beginning after December 15, 2005. Retrospective application in accordance with SFAS 154 is permitted but not required. The adoption of FSP FAS 13-1 did not have a material effect on the consolidated financial statements of the Company.

In June 2005, the Emerging Issues Task Force issued EITF 04-05, “Determining Whether a General Partner, or the General Partners as a Group, Controls a Limited Partnership or Similar Entity When the Limited Partners Have Certain Rights” (“EITF 04-05”). The scope of EITF 04-05 is limited to limited partnerships or similar entities that are not variable interest entities under FIN 46R. The Task Force reached a consensus that the general partners in a limited partnership (or similar entity) are presumed to control the entity regardless of the level of their ownership and, accordingly, may be required to consolidate the entity. This presumption may be overcome if the agreements provide the limited partners with either (a) the substantive ability to dissolve (liquidate) the limited partnership or otherwise remove the general partners without cause or (b) substantive participating rights. If it is deemed that the limited partners’ rights overcome the presumption of control by a general partner of the limited partnership, the general partner shall account for its investment in the limited partnership using the equity method of accounting. EITF 04-05 was effective immediately for all arrangements created or modified after June 29, 2005. For all other arrangements, application of EITF 04-05 is required effective for the first reporting period in fiscal years beginning after December 15, 2005 (i.e., effective January 1, 2006 for the Company) using either a cumulative-effect-type adjustment or using a retrospective application. The adoption of EITF 04-05 did not have an effect on the Company’s consolidated financial statements.

June 30, 2006

In May 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections” (“SFAS 154”). SFAS 154 replaces APB No. 20, “Accounting Changes” and SFAS No. 3, “Reporting Accounting Changes in Interim Financial Statements” and establishes retrospective application as the required method for reporting a change in accounting principle. SFAS 154 provides guidance for determining whether a retrospective application of a change in accounting principle is impracticable and for reporting a change when retrospective application is impracticable. SFAS 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. The Company adopted SFAS 154 on January 1, 2006 and this adoption had no effect on the Company’s financial position and results of operations.

In March 2005, the FASB issued FIN 47, Accounting for Conditional Asset Retirement Obligations, an interpretation of FASB Statement No. 143, Asset Retirement Obligations. FIN 47 provides clarification of the term “conditional asset retirement obligation” as used in SFAS 143, defined as a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the company. Under this standard, a company must record a liability for a conditional asset retirement obligation if the fair value of the obligation can be reasonably estimated. FIN 47 became effective in the Company’s fiscal quarter ended December 31, 2005. The Company adopted FIN 47 as required effective December 31, 2005 and the initial application of FIN 47 did not have a material effect on the consolidated financial statements of the Company.

In December 2004, the FASB issued SFAS No. 123(R), “Share-Based Payment” (“SFAS 123(R)”). SFAS 123(R) is an amendment of SFAS 123 and requires that the compensation cost relating to share-based payment transactions be recognized in the financial statements. The cost is required to be measured based on the fair value of the equity or liability instruments issued. SFAS 123(R) also contains additional minimum disclosures requirements including, but not limited to, the valuation method and assumptions used, amounts of compensation capitalized and modifications made. The effective date of SFAS 123(R) was subsequently amended by the SEC to be as of the beginning of the first interim or annual reporting period of the first fiscal year that begins on or after December 15, 2005, and allows several different methods of transition. The Company adopted SFAS 123(R) using the prospective method on January 1, 2006. This adoption did not have a material effect on our consolidated financial statements.

On January 5, 2006, the Company acquired Prentiss Properties Trust (“Prentiss”) under an Agreement and Plan of Merger (the “Merger Agreement”) that the Company entered into with Prentiss on October 3, 2005. In conjunction with the Company’s acquisition of Prentiss, designees of The Prudential Insurance Company of America (“Prudential”) acquired certain of Prentiss’ properties that contain an aggregate of approximately 4.32 million net rentable square feet for a total consideration of approximately $747.7 million. Through its acquisition of Prentiss (and after giving effect to the Prudential acquisition of certain of Prentiss’ properties), the Company acquired a portfolio of 79 office properties (includes 13 properties that are owned by consolidated joint ventures and 7 properties that are owned by an unconsolidated joint venture) that contain an aggregate of 14.0 million net rentable square feet. The results of the operations of Prentiss have been included in the Company’s condensed consolidated financial statements since January 5, 2006.

Subsequent to its acquisition of Prentiss and the related sale of certain properties to Prudential, the Company sold nine of these acquired properties that contain an aggregate of 1.7 million net rentable square feet. Two additional properties acquired in the acquisition of Prentiss are classified as held for sale at June 30, 2006.

The Company funded the approximately $1.05 billion cash portion of the merger consideration, related transaction costs and prepayments of approximately $543.3 million in Prentiss mortgage debt at the closing of the merger through (i) a $750 million unsecured term loan that matures on January 4, 2007; (ii) approximately $676.5 million of cash from Prudential’s acquisition of certain of the Prentiss properties; and (iii) approximately $195.0 million through borrowing under a revolving credit facility.

In the acquisition of Prentiss, each then outstanding Prentiss common share was converted into the right to receive 0.69 of a Brandywine common share and $21.50 in cash (the “Per Share Merger Consideration”) except that 497,884 Prentiss common shares held in the Prentiss Deferred Compensation Plan converted solely into 720,737 Brandywine common shares. In addition, each then outstanding unit (each, a “Prentiss OP Unit”) of limited partnership interest in the Prentiss operating partnership subsidiary was, at the option of the holder, converted into Prentiss Common Shares with the right to receive the Per Share Merger Consideration or 1.3799 Class A Units of the Operating Partnership (“Brandywine Class A Units”). Accordingly, based on 49,375,723 Prentiss common shares outstanding and 139,000 Prentiss OP Units electing to receive merger consideration at closing of the acquisition, the Company issued 34,541,946 Brandywine common shares and paid an aggregate of approximately $1.05 billion in cash to the accounts of the former Prentiss shareholders. Based on 1,572,612 Prentiss OP Units outstanding at closing of the acquisition that did not elect to receive merger consideration, the Operating Partnership issued 2,170,047 Brandywine Class A Units. In addition, options issued by Prentiss that were exercisable for an aggregate of 342,662 Prentiss common shares were converted into options exercisable for an aggregate of 496,037 Brandywine common shares at a weighted average exercise price of $22.00 per share. Through the Company’s acquisition of Prentiss we also assumed approximately $611.2 million in aggregate principal amount of Prentiss debt.

Each Brandywine Class A Unit that was issued in the merger is subject to redemption at the option of the holder. The Operating Partnership may, at its option, satisfy the redemption either for an amount, per unit, of cash equal to the then market price of one Brandywine common share (based on the prior ten-day trading average) or for one Brandywine common share.

For purposes of computing the total purchase price reflected in the financial statements, the common shares, operating units, restricted shares and options that were issued in the Prentiss transaction were valued based on the average trading price per Brandywine common share of $29.54. The average trading price was based on the average of the high and low trading prices for each of the two trading days before, the day of and the two trading days after the merger was announced (i.e., September 29, September 30, October 3, October 4 and October 5).

The Company considered the provisions of FIN 47 for these acquisitions and where necessary, recorded a conditional asset retirement obligation as part of the purchase price. The aggregate asset retirement recorded in connection with the Prentiss acquisition was approximately $2.7 million.

Pro forma information relating to the acquisition of Prentiss is presented below as if Prentiss was acquired and the related financing transactions occurred on January 1, 2005.

4. INVESTMENT IN UNCONSOLIDATED VENTURES

As of June 30, 2006, the Company had an aggregate investment of approximately $76.1 million in eleven unconsolidated Real Estate Ventures (net of returns of investment). The Company or Prentiss formed these ventures with unaffiliated third parties to develop office properties or to acquire land in anticipation of possible development of office properties. Nine of the Real Estate Ventures own 15 office buildings that contain an aggregate of approximately 2.7 million net rentable square feet, one Real Estate Venture developed a hotel property that contains 137 rooms and one Real Estate Venture is developing an office property located in Albemarle County, VA.

The Company also has investments in four real estate ventures that are variable interest entities under FIN No. 46R and of which the Company is the primary beneficiary.

The Company accounts for its non-consolidating interests in its Real Estate Ventures using the equity method. Non-consolidating ownership interests range from 6% to 50%, subject to specified priority allocations in certain of the Real Estate Ventures. The Company’s investments, initially recorded at cost, are subsequently adjusted for the Company’s share of the Real Estate Ventures’ income or loss and cash contributions and distributions.

The amounts reflected below (except for Company’s share of equity and income) are based on the historical financial information of the individual Real Estate Ventures. One of the Real Estate Ventures, acquired in connection with the Prentiss acquisition, had a negative equity balance on a historical cost basis as a result of historical depreciation and distribution of excess financing proceeds. The Company reflected its acquisition of this Real Estate Venture interest at its relative fair value as of the date of the purchase of Prentiss. The difference between allocated cost and the underlying equity in the net assets of the investee is accounted for as if the entity were consolidated (i.e., allocated to the Company’s relative share of assets and liabilities with an adjustment to recognize equity in earnings for the appropriate additional depreciation/amortization).

The following is a summary of the financial position of the Real Estate Ventures as of June 30, 2006 and December 31, 2005 (in thousands):

	June 30, 2006		December 31, 2005

Operating property, net of accumulated depreciation	$	355,511	$	286,601
Other assets		50,888		32,267
Liabilities		25,691		24,855
Debt		331,170		205,018
Equity		49,538		88,995
Company’s investment in real estate ventures		76,113		13,331

In addition to its $76.1 million investment in the eleven unconsolidated Real Estate Ventures, the Company also has an investment of $2.3 million in Prentiss Properties Capital Trust I and Prentiss Properties Capital Trust II that is accounted for using the cost method of accounting. This investment, which is included in investment in unconsolidated ventures at June 30, 2006, was acquired by the Company as part of the Prentiss acquisition on January 5, 2006.

The following is a summary of results of operations of the Real Estate Ventures for the three- and six-month periods ended June 30, 2006 and 2005 (in thousands):

(b) Loans were assumed as part of the acquisition of Prentiss. Interest rates presented above reflect the market rate at time of acquisition.

The indenture relating to the $300 million 2009, $275 million 2009, $300 million 2010, $300 million 2012, $250 million 2014 and $250 million 2016 unsecured notes contains various financial restrictions and requirements, including (1) a leverage ratio not to exceed 60%, (2) a secured debt leverage ratio not to exceed 40%, (3) a debt service coverage ratio of greater than 1.5 to 1.0, and (4) an unencumbered asset value of not less than 150% of unsecured debt. In addition, the note purchase agreement relating to the 2008 unsecured notes contains covenants that are similar to the above covenants.

8. SECURED NOTE PAYABLE

As the result of a voluntary defeasance that was completed in the fourth quarter of 2005 by Prentiss, the Company has a secured note payable with a maturity date of February 2007. As of June 30, 2006, the outstanding balance on the secured note payable is $183.2 million. On October 7, 2005, Prentiss exercised the right to complete a voluntary defeasance of its $180.1 million PPREFI portfolio loan collateralized by certain properties acquired by the Company. Pursuant to the defeasance, Prentiss transferred the mortgage loan to an unrelated successor entity along with the proceeds necessary to acquire U.S. Treasury Securities sufficient to cover debt service including both interest and principal payments from the defeasance date through maturity of the loan. The U.S. Treasury Securities are included in investment in marketable securities on the balance sheet. The loan may be repaid at par beginning in November 2006. The Company intends to elect to prepay the loan at par when allowed to do so, at which point the Company expects to receive a portion of the proceeds of the sales of the securities in excess of the loan balance.

9. UNSECURED CREDIT FACILITY

The Company utilizes credit facility borrowings for general business purposes, including the acquisition, development and redevelopment of properties and the repayment of other debt. In December 2005, the Company replaced its then existing credit facility with a $600.0 million unsecured credit facility (the “Credit Facility”) that matures in December 2009, subject to a one-year extension option. Borrowings under the Credit Facility generally bear interest at LIBOR plus a spread over LIBOR ranging from 0.55% to 1.10% based on the Company’s unsecured senior debt rating. The Company has the option to increase the Credit Facility to $800.0 million subject to the absence of any defaults and the

BRANDYWINE REALTY TRUST

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

June 30, 2006

Company’s ability to acquire additional commitments from its existing lenders or new lenders. As of June 30, 2006, the Company had $195.0 million of borrowings and $23.4 million of letters of credit outstanding under the Credit Facility, leaving $381.6 million of unused availability. For the six-month periods ended June 30, 2006 and 2005, the weighted-average interest rate on the Company’s unsecured credit facilities, including the effect of interest rate hedges, was 5.48% during 2006 and 4.06% during 2005.

The Credit Facility requires the maintenance of certain ratios related to minimum net worth, debt-to-total capitalization and fixed charge coverage and various non-financial covenants.

10. RISK MANAGEMENT AND USE OF FINANCIAL INSTRUMENTS

Risk Management

In the normal course of its on-going business operations, the Company encounters economic risk. There are three main components of economic risk: interest rate risk, credit risk and market risk. The Company is subject to interest rate risk on its interest-bearing liabilities. Credit risk is the risk of inability or unwillingness of tenants to make contractually required payments. Market risk is the risk of declines in the value of properties due to changes in rental rates, interest rates or other market factors affecting the valuation of properties held by the Company.

Use of Derivative Financial Instruments

The Company’s use of derivative instruments is limited to the utilization of interest rate agreements or other instruments to manage interest rate risk exposures and not for speculative purposes. The principal objective of such arrangements is to minimize the risks and/or costs associated with the Company’s operating and financial structure, as well as to hedge specific transactions. The counterparties to these arrangements are major financial institutions with which the Company and its affiliates may also have other financial relationships. The Company is potentially exposed to credit loss in the event of non-performance by these counterparties. However, because of the high credit ratings of the counterparties, the Company does not anticipate that any of the counterparties will fail to meet these obligations as they come due. The Company does not hedge credit or property value market risks.

The Company formally assesses, both at inception of the hedge and on an on-going basis, whether each derivative is highly-effective in offsetting changes in cash flows of the hedged item. If management determines that a derivative is not highly-effective as a hedge or if a derivative ceases to be a highly-effective hedge, the Company will discontinue hedge accounting prospectively.

Concentration of Credit Risk

Concentrations of credit risk arise when a number of tenants related to the Company’s investments or rental operations are engaged in similar business activities, or are located in the same geographic region, or have similar economic features that would cause their inability to meet contractual obligations, including those to the Company, to be similarly affected. The Company regularly monitors its tenant base to assess potential concentrations of credit risk. Management believes the current credit risk portfolio is reasonably well diversified and does not contain any unusual concentration of credit risk. No tenant accounted for 5% or more of the Company’s rents during the three- and six-month periods ended June 30, 2006 or 2005.

11. DISCONTINUED OPERATIONS

For the three- and six-month periods ended June 30, 2006, income from discontinued operations relates to nine properties that the Company sold during 2006 and two properties designated as held-for-sale as of June 30, 2006. These properties were acquired by the Company as part of its acquisition of Prentiss.

16. COMMITMENTS AND CONTINGENCIES

Legal Proceedings

The Company is involved from time to time in litigation on various matters, including disputes with tenants and disputes arising out of agreements to purchase or sell properties. Given the nature of the Company’s business activities, these lawsuits are considered routine to the conduct of its business. The result of any particular lawsuit cannot be predicted, because of the very nature of litigation, the litigation process and its adversarial nature, and the jury system. The Company does not expect that the liabilities, if any, that may ultimately result from such legal actions will have a material adverse effect on the consolidated financial position, results of operations or cash flows of the Company.

There have been lawsuits against owners and managers of multifamily and office properties asserting claims of personal injury and property damage caused by the presence of mold in residential units or office space. The Company has been named as a defendant in two lawsuits in the State of New Jersey that allege personal injury as a result of the presence of mold. In 2005, one lawsuit was dismissed by way of summary judgment with prejudice. Unspecified damages are sought on the remaining lawsuit. The Company has referred this lawsuit to its environmental insurance carrier and, as of the date of this Form 10-Q, the insurance carrier is tendering a defense to this claim.

Environmental

As an owner of real estate, the Company is subject to various environmental laws of federal, state, and local governments. The Company’s compliance with existing laws has not had a material adverse effect on its financial condition and results of operations, and the Company does not believe it will have a material adverse effect in the future. However, the Company cannot predict the impact of unforeseen environmental contingencies or new or changed laws or regulations on its current Properties or on properties that the Company may acquire.

Related Party Transaction

The Company holds a fifty percent economic interest in an approximately 141,724 square foot office building located at 101 Paragon Drive, Montvale, New Jersey. The remaining fifty percent interest is held by Donald E. Axinn, one of the Company’s Trustees. Although the Company and Mr. Axinn have each committed to provide one half of the $11.0 million necessary to repay the mortgage loan secured by this property, in February 2006, an unaffiliated third party entered into an agreement to purchase this property for $18.3 million. Closing is scheduled for the third quarter of 2006 and is subject to standard closing conditions.

Ground Rent

Future minimum rental payments under the terms of all non-cancelable ground leases under which the Company is the lessee are expensed on a straight-line basis regardless of when payments are due.

Other Commitments or Contingencies

As part of the Company’s September 2004 acquisition of a portfolio of 14 properties (the “TRC Acquisition”), the Operating Partnership agreed to issue to the sellers up to a maximum of $9.7 million of Class A Units of the Operating Partnership if certain of the acquired properties achieve at least 95% occupancy prior to September 21, 2007. At June 30, 2006, the maximum amount payable under this arrangement was $3.3 million.

As part of the TRC acquisition, the Company acquired an interest in Two Logan Square, a 696,477 square foot office building in Philadelphia, Pennsylvania, primarily through a second and third mortgage secured by this property pursuant to which the Company receives substantially all cash flows from the property. The Company currently does not expect to take title to Two Logan Square until, at the earliest, September 2019. In the event that the Company takes title to Two Logan Square upon a foreclosure of its mortgages, the Company has agreed to make a payment to an unaffiliated third party with a residual interest as a fee owner of this property. The amount of the payment would be $0.6 million if the Company must pay a state and local transfer tax upon taking title, or $2.9 million if no transfer tax is payable upon the transfer.

As part of the Prentiss acquisition, TRC acquisition and several of our other acquisitions, the Company has agreed not to sell certain of the acquired properties. In the case of TRC, the Company agreed not to sell certain of the acquired properties for periods ranging from three to 15 years from the acquisition date as follows: 201 Radnor Financial Center, 555 Radnor Financial Center and 300 Delaware Avenue (three years); One Rodney Square and 130/150/170 Radnor Financial Center (10 years); and One Logan Square, Two Logan Square and Radnor Corporate Center (15 years). In the case of the Prentiss acquisition, we assumed the obligation of Prentiss not to sell Concord Airport Plaza before March 2018 and 6600 Rockledge before July 2008. The Company also owns 14 other properties that aggregate 1.0 million square feet and has agreed not to sell these properties for periods that expire through 2008. These agreements generally provide that we may dispose of the subject Properties only in transactions that qualify as tax-free exchanges under Section 1031 of the Code or in other tax deferred transactions. In the event that the Company sells any of the properties within the applicable restricted period in non-exempt transactions, the Company has agreed to pay significant tax liabilities that would be incurred by the parties who sold the applicable property.

The Company invests in its Properties and regularly incurs capital expenditures in the ordinary course of business to maintain the Properties. The Company believes that such expenditures enhance the competitiveness of the Properties. The Company also enters into construction, utility and service contracts in the ordinary course of business which may extend beyond one year. These contracts include terms that provide for cancellation with insignificant or no cancellation penalties.

17. SHARE REPURCHASE PROGRAM

The Company repurchased 1,180,200 shares during the six month period ending June 30, 2006 for an aggregate consideration of $34.5 million under its share repurchase program. As of June 30, 2006, the Company may purchase an additional 2,319,800 shares under the plan. Repurchases may be made 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 the Company to repurchase any shares. The Company may discontinue the program at any time.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for forward-looking statements. This Quarterly Report on Form 10-Q and other materials filed by us with the SEC (as well as information included in oral or other written statements made by us) contain statements that are forward-looking, including statements relating to business and real estate development activities, acquisitions, dispositions, future capital expenditures, financing sources, governmental regulation (including environmental regulation) and competition. The words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “will,” “should” and similar expressions, as they relate to us, are intended to identify forward-looking statements. Although we believe that the expectations reflected in such forward-looking statements are based on reasonable assumptions, we can give no assurance that our expectations will be achieved. As forward-looking statements, these statements involve important risks, uncertainties and other factors that could cause actual results to differ materially from the expected results and, accordingly, such results may differ from those expressed in any forward-looking statements made by us or on our behalf. Factors that could cause actual results to differ materially from our expectations include, but are not limited to, changes in general economic conditions, changes in local real estate conditions (including changes in rental rates and the number of competing properties), changes in the economic conditions affecting industries in which our principal tenants compete, our failure to lease unoccupied space in accordance with our projections, our failure to re-lease occupied space upon expiration of leases, the bankruptcy of major tenants, changes in prevailing interest rates, the unavailability of equity and debt financing, unanticipated costs associated with the acquisition and integration of our acquisitions, unanticipated costs to complete and lease-up pending developments, impairment charges, increased costs for, or lack of availability of, adequate insurance, including for terrorist acts, demand for tenant services beyond those traditionally provided by landlords, potential liability under environmental or other laws, earthquakes and other natural disasters, the existence of complex regulations relating to our status as a REIT and to our acquisition, disposition and development activities, the adverse consequences of our failure to qualify as a REIT, the impact of newly adopted accounting principles on our accounting policies and on period-to-period comparisons of financial results and the other risks identified in the “Risk Factors” section and elsewhere in our Annual Report on Form 10-K for the year ended December 31, 2005. Given these uncertainties, we caution readers not to place undue reliance on forward-looking statements. We assume no obligation to update or supplement forward-looking statements that become untrue because of subsequent events.

OVERVIEW

As of June 30, 2006, we managed our portfolio within nine geographic segments: (1) Pennsylvania—West, (2) Pennsylvania—North, (3) New Jersey, (4) Urban, (5) Virginia, (6) California—North, (7) California—South, (8) Mid-Atlantic and (9) Southwest. We believe we have established an effective platform in these office and industrial markets for maximizing market penetration, optimizing operating economies of scale and creating long-term investment value.

Subsequent to our acquisition of Prentiss and the related sale of certain of Prentiss’s properties to Prudential, we sold nine additional properties that contain an aggregate of 1.7 million net rentable square feet.

As of June 30, 2006, our portfolio consisted of 278 office properties, 23 industrial facilities and one mixed-use property that contain an aggregate of approximately 30.3 million net rentable square feet. We held economic interests in eleven unconsolidated real estate ventures that contain approximately 2.7 million net rentable square feet (the “Real Estate Ventures”) formed with third parties to develop or own commercial properties. In addition, as of June 30, 2006 we owned interests in four consolidated real estate ventures that own 16 office properties containing approximately 1.6 million net rentable square feet.

We receive income primarily from rental revenue (including tenant reimbursements) from our properties and, to a lesser extent, from the management of properties owned by third parties and from investments in the Real Estate Ventures.

Our financial performance is dependent upon the demand for office, industrial and other commercial space in our markets and upon prevailing interest rates.

We continue to seek revenue growth through an increase in occupancy of our portfolio and our investment strategies. Our occupancy was 91.6% at June 30, 2006, or 90.5% including four lease-up properties that we acquired in our September 2004 acquisition of a portfolio of 14 properties (the “TRC Properties” or the “TRC acquisition”).

The Prentiss acquisition and the TRC acquisition, and to a lesser extent, other property acquisitions have already or will materially impact our operations. Accordingly, the reported historical financial information for periods prior to these transactions is not believed to be fully indicative of our future operating results or financial condition.

Through our January 2006 acquisition of Prentiss, we acquired interests in properties that contain an aggregate of 14.0 million net rentable square feet. Through this acquisition, we also entered into new markets, including markets in California, Northern Virginia, Maryland, and Texas.

As we seek to increase revenue through our operating activities, our management also focuses on strategies to minimize operating risks, including (i) tenant rollover risk, (ii) tenant credit risk and (iii) development risk.

Tenant Rollover Risk:

We are subject to the risk that tenant leases, upon expiration, are not renewed, that space may not be relet, or that the terms of renewal or reletting (including the cost of renovations) may be less favorable to us than the current lease terms. Leases accounting for approximately 5.1% of our aggregate annualized base rents as of June 30, 2006 (representing approximately 5.1% of the net rentable square feet of the Properties) expire without penalty through the end of 2006. We maintain an active dialogue with our tenants in an effort to achieve a high level of lease renewals. Our retention rate for leases that were scheduled to expire in the six-month period ended June 30, 2006 was 83.0%. If we were unable to renew leases for a substantial portion of the space under expiring leases, or to promptly relet this space, at anticipated rental rates, our cash flow would be adversely impacted.

Tenant Credit Risk:

In the event of a tenant default, we may experience delays in enforcing our rights as a landlord and may incur substantial costs in protecting our investment. Our management regularly evaluates our accounts receivable reserve policy in light of its tenant base and general and local economic conditions. The accounts receivable allowances were $7.8 million or 8.8% of total receivables (including accrued rent receivable) as of June 30, 2006 compared to $4.9 million or 7.6% of total receivables (including accrued rent receivable) as of December 31, 2005.

Development Risk:

As of June 30, 2006, we had in development or redevelopment ten sites aggregating approximately 2.1 million square feet. We estimate the total cost of these projects to be $510.7 million and we had incurred $267.3 million of these costs as of June 30, 2006. We are actively marketing space at these projects to prospective tenants but can provide no assurance as to the timing or terms of any leases of space at these projects. As of June 30, 2006, we owned approximately 369 acres of undeveloped land. Risks associated with development of this land include construction cost increases or overruns and construction delays, insufficient occupancy rates, building moratoriums and inability to obtain zoning, land-use, building, occupancy and other required governmental approvals.

ACQUISITIONS AND DISPOSITIONS OF REAL ESTATE INVESTMENTS

On January 5, 2006, we acquired Prentiss under an Agreement and Plan of Merger that we entered into with Prentiss on October 3, 2005. In conjunction with our acquisition of Prentiss, designees of The Prudential Insurance Company of America (“Prudential”) acquired certain Prentiss properties that contain an aggregate of approximately 4.32 million net rentable square feet for total consideration of approximately $747.7 million. Through our acquisition of Prentiss (and after giving effect to the Prudential acquisition of certain Prentiss properties), we acquired a portfolio of 79 office properties (including 13 properties that are owned by consolidated real estate ventures and seven properties that are owned by unconsolidated real estate ventures) that contain an aggregate of 14.0 million net rentable square feet.

Subsequent to our acquisition of Prentiss and the related sale of properties to Prudential, through June 30, 2006, we sold nine additional properties acquired from Prentiss that contain an aggregate of 1.7 million net rentable square feet.

In our acquisition of Prentiss, each then outstanding Prentiss common share was converted into the right to receive 0.69 of a Brandywine common share and $21.50 in cash except that 497,884 Prentiss common shares held in the Prentiss

Deferred Compensation Plan converted solely into 720,737 Brandywine common shares. In addition, each then outstanding unit of limited partnership interest in Prentiss’s operating partnership subsidiary was, at the option of the holder, converted into Prentiss Common Shares with the right to receive the per share merger consideration or 1.3799 Class A Units of our Operating Partnership. Accordingly, based on 49,375,723 Prentiss common shares outstanding and 139,000 Prentiss OP Units electing to receive merger consideration at closing of the acquisition, we issued 34,541,946 Brandywine common shares and paid an aggregate of approximately $1.05 billion in cash for the accounts of the former Prentiss shareholders. Based on 1,572,612 Prentiss OP Units outstanding at closing of the acquisition, we issued 2,170,047 Brandywine Class A Units. In addition, options issued by Prentiss that were exercisable for an aggregate of 342,662 Prentiss common shares were converted into options exercisable for an aggregate of 496,037 Brandywine common shares at a weighted average exercise price of $22.00 per share. Through our acquisition of Prentiss we assumed approximately $611.2 million in aggregate principal amount of Prentiss debt.

Each Brandywine Class A Unit that we issued in the merger is subject to redemption at the option of the holder. At our option, we may satisfy the redemption either for an amount, per unit, of cash equal to the then market price of one Brandywine common share (based on the prior ten-day trading average) or for one Brandywine common share.

During the six-month period ended June 30, 2006, we also acquired two office properties containing 238,107 net rentable square feet and 76.6 acres of developable land for an aggregate purchase price of $47.4 million. We sold two parcels of land containing 6.8 acres for an aggregate $4.9 million, realizing net gains totaling $2.6 million.

During the three-month period ended June 30, 2006, we acquired one office property containing 145,127 net rentable square feet for $24.0 million and 76.6 acres of developable land for an aggregate purchase price of $47.4 million. We sold two parcels of land containing 6.8 acres for an aggregate $4.9 million, realizing net gains totaling $2.6 million.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Management’s Discussion and Analysis of Financial Condition and Results of Operations discusses our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Certain accounting policies are considered to be critical accounting policies, as it requires management to make assumptions about matters that are highly uncertain at the time the estimate is made and changes in accounting policies are reasonably likely to occur from period to period. Management bases its estimates and assumptions on historical experience and current economic conditions. On an on-going basis, management evaluates its estimates and assumptions including those related to revenue, impairment of long-lived assets and the allowance for doubtful accounts. Actual results may differ from those estimates and assumptions.

Our Annual Report on Form 10-K for the year ended December 31, 2005 contains a discussion of our critical accounting policies. There have been no significant changes in our critical accounting policies since December 31, 2005. See also Note 2 in our unaudited consolidated financial statements for the six-month period ended June 30, 2006 as set forth herein. Management discusses our critical accounting policies and management’s judgments and estimates with our Audit Committee.

(c) - Includes net termination fee income of $1,069 for 2006 and $856 for 2005 for the same store property portfolio and $208 for 2006 for the Prentiss portfolio

(d) - Operations of two properties classified as held for sale are included in income from discontinued operations

Revenue

Revenue increased by $75.5 million primarily due to the acquisition of Prentiss, which represents $65.1 million of this increase. The increase is also the result of two properties that we acquired in the fourth quarter of 2005, one property acquired in the first quarter of 2006, one property acquired in the second quarter of 2006 and additional tenant occupancy at Cira Centre.

Operating Expenses and Real Estate Taxes

Property operating expenses increased by $21.3 million primarily due to the acquisition of Prentiss, which represents $19.9 million of this increase. Property operating expenses attributable to the occupied portion of Cira Centre and other properties acquired accounted for the remainder of the increase.

Real estate taxes increased by $7.1 million primarily due to the acquisition of Prentiss, which represents $6.3 million of this increase. The remainder of the increase is the result of increased real estate tax assessments and properties acquired.

Depreciation and Amortization Expense

Depreciation and amortization increased by $45.0 million primarily due to the acquisition of Prentiss, which increased total portfolio depreciation expense by $31.4 million. A significant portion of the increase is also due to accelerated depreciation expense for one of our properties totaling $11.9 million that is associated with the planned demolition of an existing building as part of an office park development in suburban Philadelphia.. This property was part of our same store portfolio, therefore the remaining increase in depreciation and amortization for our same store portfolio is $2.1 million. This increase resulted from the timing of assets being placed in service upon completion of tenant improvement and capital improvement projects subsequent to the end of the three month period ending June 30, 2005.

Administrative Expenses

Administrative expenses increased by approximately $3.3 million primarily due to the acquisition of Prentiss. Of this increase, $1.0 million was primarily attributable to increased payroll and related costs associated with employees that we hired as part of the acquisition of Prentiss. We also incurred an additional $1.7 million in professional fees in connection with our merger integration activities. The remainder of the increase reflects other increased costs of the combined companies.

Interest Income/ Expense

Interest expense increased by approximately $24.7 million primarily as a result of 14 fixed rate mortgages, three unsecured notes, and one note secured by U.S. treasury notes (“PPREFI debt”) that we assumed in the Prentiss merger. The mortgages assumed have maturity dates ranging from July 2009 through March 2016 and the unsecured notes have maturities of March, April, and July 2035, and the PPREFI debt has a maturity of February 2007.

The PPREFI debt was defeased by Prentiss in the fourth quarter of 2005 and is secured by an investment in U.S. treasury notes. The interest earned on the treasury notes is included in interest income and substantially offsets the amount of interest expense incurred on the PPREFI debt, resulting in an immaterial amount of net interest expense incurred. The increase of $2.3 million in interest income is attributable to the interest income earned on these treasury notes.

See the Notes to the Unconsolidated Combined Financial Statements in Part I, Item I for details of our mortgage indebtedness and unsecured notes outstanding.

Minority Interest-partners’ share of consolidated real estate ventures

Minority interest-partners’ share of consolidated real estate ventures increased by $0.1 million from the prior year as a result of our acquisition of one consolidated joint venture as part of our acquisition of Prentiss. This consolidated joint venture, of which we own 51%, owns 13 properties which aggregate approximately 1.2 million square feet of office space.

Subsequent to our acquisition of Prentiss, we entered into a joint venture with IBM. We consolidate this joint venture, and own a 50% interest in it.

As of June 30, 2006 we held an ownership interest in 16 properties through consolidated joint ventures, compared to two properties owned by consolidated joint ventures at March 31, 2005.

Minority Interest attributable to continuing operations – LP units

Minority interest attributable to continuing operations – LP units, represents the equity in loss (income) attributable to the portion of the Operating Partnership not owned by us. The increase from the prior year is primarily the result of the fact that at June 30, 2006 the LP units share in our net loss compared to their share of net income in the prior year. Minority interests owned 4.3% and 3.4% of the Operating Partnership as of June 30, 2006 and 2005, respectively.

Discontinued Operations

Discontinued operations increased by $0.1 million from the prior year as a result of the sale of one property in Allen, TX that we acquired in the Prentiss acquisition. We also have one property in Chicago, IL and one property in Dallas, TX that we classified as held for sale at June 30, 2006. These three properties combined had net operating income of $0.1 million during the quarter ended June 30, 2006. There were no gains or losses recognized on the property that was sold, or on the properties held for sale, as the proceeds received from the sale of these properties was equal to, or is expected to equal, the amount of the total purchase price allocated to these assets.

Net Income

Net income declined in the second quarter of 2006, compared to the second quarter of 2005, by $20.5 million as increased revenues were not sufficient to offset increases in operating costs (primarily depreciation and amortization) and financing costs. All major financial statement captions increased as a result of our acquisition of Prentiss and the related financing required to complete the transaction. A significant element of these costs relate to additional depreciation and amortization charges relating to the significant property additions (including both the TRC acquisition and the Prentiss acquisition) and the values ascribed to related acquired intangibles (e.g., in-place leases). These charges do not affect our ability to pay dividends and may not be comparable to those of other real estate companies that have not made such acquisitions. Such charges can be expected to continue until the values ascribed to the lease intangibles are fully amortized. These intangibles are amortizing over the related lease terms or estimated tenant relationship. In addition, a significant portion of the decrease in net income is attributable to the $11.9 million in depreciation expense described in the Depreciation and Amortization Expense section above.

Earnings Per Share

Earnings per share has declined from $0.12 in the second quarter of 2005 to $(0.15) in the second quarter of 2006 as a result of the factors described in “Net Income” above and an increase in the average number of common shares outstanding. We issued 34.6 million of our common shares in our acquisition of Prentiss.

Comparison of the Six-Month Periods Ended June 30, 2006 and 2005

The table below shows selected operating information for the Same Store Property Portfolio and the Total Portfolio. The Same Store Property Portfolio consists of 240 Properties containing an aggregate of approximately 18.0 million net rentable square feet that we owned for the entire six-month periods ended June 30, 2006 and 2005. This table also includes a reconciliation from the Same Store Property Portfolio to the Total Portfolio net income (i.e., all properties owned by us during the six-month periods ended June 30, 2006 and 2005) by providing information for the properties which were acquired, under development or placed into service and administrative/elimination information for the six-month periods ended June 30, 2006 and 2005 (in thousands).

Revenue

Revenue increased by $139.5 million primarily due to the acquisition of Prentiss, which represents $127.3 million of this increase. The operations of the properties acquired from Prentiss contributed $125.5 million to this increase and $1.8 million resulted from additional third party management fees as a result of management contracts assumed and entered into at the time of acquisition. The increase is also the result of two properties that were acquired in the fourth quarter of 2005, one property acquired in the first quarter of 2006, and one property acquired in the second quarter of 2006, as well as additional tenant occupancy at Cira Centre that will continue throughout 2006.

These increases are offset by the $4.5 million decrease in revenue from our same store properties for the six month period ended June 30, 2006. This decrease is the result of a $3.3 million decrease in termination fee income and a $2.0 million decrease in tenant reimbursements. The decrease in tenant reimbursements is due to less billable property operating expense incurred in the six month period ending June 30, 2006.

Operating Expenses and Real Estate Taxes

Property operating expenses increased by $39.6 million primarily due to the acquisition of Prentiss, which represents $37.6 million of this increase. Property operating expenses attributable to the occupied portion of Cira Centre and other property acquisitions accounted for the remainder of the increase. These increases are offset by a $1.6 million decrease in operating expenses for our same store properties. The decrease in the operating expenses of the same store properties is attributable to less snow removal costs and HVAC maintenance costs incurred.

Real estate taxes increased by $13.9 million primarily due to the acquisition of Prentiss, which represents $12.2 million of this increase. The remainder of the increase is the result of increased real estate tax assessments and properties acquired.

Depreciation and Amortization Expense

Depreciation and amortization increased by $75.9 million primarily due to the acquisition of Prentiss, which increased total portfolio depreciation expense by $62.5 million. A significant portion of the increase is also due to accelerated depreciation expense for one of our properties totaling $11.9 million that is associated with the planned demolition of an existing building as part of an office park development in suburban Philadelphia.. This property was part of our same store portfolio, therefore the remaining increase in depreciation and amortization for our same store portfolio is $0.4 million. This increase resulted from the timing of assets being placed in service upon completion of tenant improvement and capital improvement projects subsequent to the end of the six month period ending June 30, 2005. The four properties that we acquired subsequent to June 30, 2005 caused an increase of $1.0 million in depreciation and amortization expense.

Administrative Expenses

Administrative expenses increased by approximately $7.1 million primarily due to the acquisition of Prentiss. Of this increase, $2.4 million was primarily attributable to increased payroll and related costs associated with employees that we hired as part of the acquisition of Prentiss. We also incurred an additional $2.9 million in professional fees in connection with our merger integration activities. The remainder of the increase reflects other increased costs of the combined companies.

Interest Income/ Expense

Interest expense increased by approximately $47.9 million primarily as a result of 14 fixed rate mortgages, three unsecured notes, and one note secured by U.S. treasury notes (“PPREFI debt”) that we assumed in the Prentiss merger. The mortgages assumed have maturity dates ranging from July 2009 through March 2016 and the unsecured notes have maturities of March, April, and July 2035, and the PPREFI debt has a maturity of February 2007.

amount of interest expense incurred on the PPREFI debt, resulting in an immaterial amount of net interest expense incurred. The increase of $4.6 million in interest income is attributable to the interest income earned on these treasury notes.

See the Notes to the Unconsolidated Combined Financial Statements in Part I, Item I for details of our mortgage indebtedness and unsecured notes outstanding.

Minority Interest-partners’ share of consolidated real estate ventures

Minority interest-partners’ share of consolidated real estate ventures increased by $0.4 million from the prior year as a result of our acquisition of one consolidated joint venture as part of our acquisition of Prentiss. This consolidated joint venture, of which we own 51%, owns 13 properties which aggregate approximately 1.2 million square feet of office space.

Subsequent to our acquisition of Prentiss, we entered into a joint venture with IBM. We consolidate this joint venture, and own a 50% interest in it.

As of June 30, 2006 we hold an ownership interest in 16 properties through consolidated joint ventures, compared to two properties owned by consolidated joint ventures at March 31, 2005.

Minority Interest attributable to continuing operations – LP units

Discontinued Operations

Discontinued operations increased by $3.3 million from the prior year as a result of the sale of seven properties in Chicago, IL, one in Dallas, TX, and one in Allen, TX that we acquired in the Prentiss acquisition. We also have one property in Chicago, IL and one property in Dallas, TX that we classified as held for sale at June 30, 2006. These eleven properties combined had net operating income of $3.3 million during the six month period ended June 30, 2006. There were no gains or losses recognized on the properties that were sold, or held for sale, as the proceeds received from the sale of these properties, or expected to be received, was equal to the amount of the total purchase price allocated to these assets.

Net Income

Net income declined in the six month period ending June 30, 2006, compared to the same period in 2005 by $32.5 million as increased revenues were not sufficient to offset increases in operating costs (primarily depreciation and amortization) and financing costs. All major financial statement captions increased as a result of our acquisition of Prentiss and the related financing required to complete the transaction. A significant element of these costs relate to additional depreciation and amortization charges relating to the significant property additions (including both the TRC acquisition and the Prentiss acquisition) and the values ascribed to related acquired intangibles (e.g., in-place leases). These charges do not affect our ability to pay dividends and may not be comparable to those of other real estate companies that have not made such acquisitions. Such charges can be expected to continue until the values ascribed to the lease intangibles are fully amortized. These intangibles are amortizing over the related lease terms or estimated tenant relationship. In addition, a significant portion of the decrease in net income is attributable to the $11.9 million in depreciation expense described in the Depreciation and Amortization Expense section above.

Earnings Per Share

Earnings per share declined from $0.26 for the six month period ended June 30, 2005 to $(0.20) in the six month period ended June 30, 2006 as a result of the factors described in “Net Income” above and an increase in the average number of common shares outstanding. We issued 34.6 million of our common shares in our acquisition of Prentiss.

LIQUIDITY AND CAPITAL RESOURCES

General

Our principal liquidity needs for the next twelve months are as follows:

•

fund normal recurring expenses,

•

fund capital expenditures, including capital and tenant improvements and leasing costs,

•

fund current development and redevelopment costs, and

•

fund distributions declared by our Board of Trustees.

We believe that our liquidity needs will be satisfied through cash flows generated by operations and financing activities. Rental revenue, expense recoveries from tenants, and other income from operations are our principal sources of cash that we use to pay operating expenses, debt service, recurring capital expenditures and the minimum distributions required to maintain our REIT qualification. We seek to increase cash flows from our properties by maintaining quality standards for our properties that promote high occupancy rates and permit increases in rental rates while reducing tenant turnover and controlling operating expenses. Our revenue also includes third-party fees generated by our property management, leasing, development and construction businesses. We believe our revenue, together with proceeds from equity and debt financings, will continue to provide funds for our short-term liquidity needs. However, material changes in our operating or financing activities may adversely affect our net cash flows. Such changes, in turn, would adversely affect our ability to fund distributions, debt service payments and tenant improvements. In addition, a material adverse change in our cash provided by operations would affect the financial performance covenants under our unsecured credit facility and unsecured notes.

Our principal liquidity needs for periods beyond twelve months are for costs of developments, redevelopments, property acquisitions, scheduled debt maturities, major renovations, expansions and other non-recurring capital improvements. We draw on multiple financing sources to fund our long-term capital needs. We use our credit facility for general business purposes, including the acquisition, development and redevelopment of properties and the repayment of other debt. In March 2006 and December 2005, we sold $850 million and $300 million, respectively of unsecured notes and expect to utilize the debt and equity markets for other long-term capital needs.

As a result of our acquisition of Prentiss, we will have additional short and long-term liquidity requirements. Historically, we have satisfied these types of requirements principally through the most advantageous source of capital at that time, which has included public offerings of unsecured debt and private placements of secured and unsecured debt, sales of common and preferred equity, capital raised through the disposition of assets, and joint venture transactions. We believe these sources of capital will continue to be available in the future to fund our capital needs.

We funded the approximately $1.05 billion cash portion of the Prentiss merger consideration, related transaction costs and prepayments of approximately $543.3 million in Prentiss mortgage debt at the closing of the merger through (i) a $750 million unsecured term loan that originally matured on January 4, 2007; (ii) approximately $676.5 million of cash from Prudential’s acquisition of certain of the Prentiss properties; and (iii) approximately $195.0 million through borrowing under our revolving credit facility. We repaid in full the $750 million term loan on March 28, 2006 with the proceeds of the $850 million unsecured notes described more fully in Capitalization below.

Our ability to incur additional debt is dependent upon a number of factors, including our credit ratings, the value of our unencumbered assets, our degree of leverage and borrowing restrictions imposed by our current lenders. We currently have investment grade ratings for prospective unsecured debt offerings from three major rating agencies. If a rating agency were to downgrade our credit rating, our access to capital in the unsecured debt market would be more limited and the interest rate under our existing credit facility would increase.

Our ability to sell common and preferred shares is dependent on, among other things, general market conditions for REITs, market perceptions about our company and the current trading price of our shares. We regularly analyze which source of capital is most advantageous to us at any particular point in time. The equity markets may not be consistently available on terms that we consider attractive.

Cash Flows

The following summary discussion of our cash flows is based on the consolidated statement of cash flows and is not meant to be an all-inclusive discussion of the changes in our cash flows for the periods presented.

As of June 30, 2006 and December 31, 2005, we maintained cash and cash equivalents of $26.4 million and $7.2 million, respectively, an increase of $19.2 million. This increase was the result of the following changes in cash flow from our activities for the six-month period ended June 30 (in thousands):

Activity	2006			2005

Operating	$	126,714		$	62,505
Investing		(957,156	)		(126,337	)
Financing		849,645			57,807

Net cash flows	$	19,203		$	(6,025	)

Our increased cash flow from operating activities in the six-months ended June 30, 2006 compared to the same period in 2005 is primarily attributable to our acquisition of Prentiss.

The increase in cash outflows from investing activities is primarily attributable to our acquisition of Prentiss and other property and land acquisitions totaling $986.0 million. In addition, we incurred approximately $102.9 million of capital expenditures for the properties that we own. These increases in investing activity are offset by the net proceeds of $144.0 million received from the sale of seven properties in Chicago and two in Texas that we acquired in our acquisition of Prentiss and subsequently sold.

Increased cash flow from financing activities is primarily attributable to the issuance of $850.0 million of unsecured notes resulting in net proceeds of $847.8 million. The proceeds of the note issuance were used to satisfy the $750.0 million term loan that was obtained in connection with the acquisition of Prentiss, as well as a portion of the outstanding borrowings on our credit facility. We also had net borrowings of $105.0 million on our line of credit. These cash inflows are offset by our repurchase of common shares totaling $34.5 million and our two distribution payments totaling $68.3 million.

Capitalization

Indebtedness

On March 28, 2006, our Operating Partnership consummated the public offering of (1) $300,000,000 aggregate principal amount of its unsecured floating rate notes due 2009 (the “2009 Notes”), (2) $300,000,000 aggregate principal amount of its 5.75% notes due 2012 (the “2012 Notes”) and (3) $250,000,000 aggregate principal amount of its 6.00% notes due 2016 (the “2016 Notes” and, together with the 2009 Notes and 2012 Notes, the “Notes”). We guaranteed the payment of principal of and interest on the Notes.

On March 28, 2006, we terminated, and repaid all amounts outstanding under, the $750 million Term Loan Agreement that we entered into on January 5, 2006 with JPMorgan Chase Bank, N.A., as Administrative Agent and Syndication Agent, J.P. Morgan Securities Inc., as Lead Arranger and Sole Bookrunner, and the lenders identified therein. We entered into the Term Loan Agreement in connection with our acquisition through the merger of Prentiss on January 5, 2006.

As of June 30, 2006, we had approximately $3.2 billion of outstanding indebtedness. The table below summarizes our mortgage notes payable, our secured note payable, our unsecured notes and our revolving credit facility at June 30, 2006 and December 31, 2005:

	June 30, 2006			December 31, 2005

	(dollars in thousands)
Balance:
Fixed rate	$	2,581,552		$	1,417,611
Variable rate		574,272			103,773

Total	$	3,155,824		$	1,521,384

Percent of Total Debt:

Weighted-average interest rate at period end:
Fixed rate		5.8	%		5.9	%
Variable rate		5.8	%		5.3	%
Total		5.8	%		5.8	%

The variable rate debt shown above generally bears interest based on various spreads over LIBOR (the term of which is selected by us).

We have used credit facility borrowings for general business purposes, including the acquisition, development and redevelopment of properties and the repayment of other debt. In December 2005, we replaced our then existing unsecured credit facility with a $600 million unsecured credit facility (the “Credit Facility”) that matures in December 2009, subject to a one year extension option upon payment of a fee and the absence of any defaults. Borrowings under the new Credit Facility generally bear interest at LIBOR (LIBOR was 5.33% as of June 30, 2006) plus a spread over LIBOR ranging from 0.55% to 1.10% based on our unsecured senior debt rating. We have an option to increase the maximum borrowings under the Credit Facility to $800 million subject to the absence of any defaults and our ability to obtain additional commitments from our existing or new lenders. The Credit Facility requires the maintenance of certain ratios related to minimum net worth, debt to total capitalization and fixed charge coverage and various non-financial covenants. We believe that we are in compliance with all financial covenants as of June 30, 2006.

We utilize unsecured notes as a long-term financing alternative. The indentures and note purchase agreements relating to our unsecured notes contain financial restrictions and requirements, including (1) a leverage ratio not to exceed 60%, (2) a secured debt leverage ratio not to exceed 40%, (3) a debt service coverage ratio of greater than 1.5 to 1.0, and (4) an unencumbered asset value of not less than 150% of unsecured debt. In addition, the note purchase agreement relating to the 2008 Notes contains covenants that are similar to the above covenants. At June 30, 2006, we were in compliance with each of these financial restrictions and requirements.

We have mortgage loans that are collateralized by certain of our properties. Payments on mortgage loans are generally due in monthly installments of principal and interest, or interest only.

We intend to refinance our mortgage loans as they mature, primarily through the use of unsecured debt or equity.

The amount of indebtedness that we may incur, and the policies with respect thereto, are not limited by our declaration of trust and bylaws, and are solely within the discretion of our board of trustees, limited only by various financial covenants in our credit agreements.

Equity

On June 15, 2006, we declared a distribution of $0.44 per Common Share, totaling $39.8 million, which we paid on July 17, 2006 to shareholders of record as of July 6, 2006. The Operating Partnership simultaneously declared a $0.44 per unit cash distribution to holders of Class A Units totaling $1.8 million.

On June 15, 2006, we declared distributions on our Series C Preferred Shares and Series D Preferred Shares to holders of record as of June 30, 2006. These shares are entitled to a preferential return of 7.50% and 7.375%, respectively. Distributions paid on July 17, 2006 to holders of Series C Preferred Shares and Series D Preferred Shares totaled $0.9 million and $1.1 million, respectively.

At June 30, 2006, we had a share repurchase program under which our Board has authorized us to repurchase from time to time up to 6,700,000 common shares. Through June 30, 2006, we had repurchased approximately 4.4 million common shares under this program at an average price of $20.82 per share. Our Board placed no time limit on the duration of the program. As of June 30, 2006, we may purchase an additional 2,319,800 additional shares under the plan.

Shelf Registration Statement

Together with our Operating Partnership, we maintain a shelf registration statement that registered common shares, preferred shares, depositary shares and warrants and unsecured debt securities. Subject to our ongoing compliance with securities laws, and if warranted by market conditions, we may offer and sell equity and debt securities from time to time under the registration statement.

Short- and Long-Term Liquidity

We believe that our cash flow from operations is adequate to fund its short-term liquidity requirements. Cash flow from operations is generated primarily from rental revenues and operating expense reimbursements from tenants and management services income from providing services to third parties. We intend to use these funds to meet short-term liquidity needs, which are to fund operating expenses, debt service requirements, recurring capital expenditures, tenant allowances, leasing commissions and the minimum distributions required to maintain our REIT qualification under the Internal Revenue Code.

We expect to meet our long-term liquidity requirements, such as for property acquisitions, development, investments in real estate ventures, scheduled debt maturities, major renovations, expansions and other significant capital improvements, through cash from operations, borrowings under its Credit Facility, other long-term secured and unsecured indebtedness, the issuance of equity securities and the proceeds from the disposition of selected assets.

Inflation

A majority of our leases provide for reimbursement of real estate taxes and operating expenses either on a triple net basis or over a base amount. In addition, many of our office leases provide for fixed base rent increases. We believe that inflationary increases in expenses will be significantly offset by expense reimbursement and contractual rent increases.

Commitments and Contingencies

The following table outlines the timing of payment requirements related to our contractual commitments as of June 30, 2006:

	Payments by Period (in thousands)

	Total		Less than 1 Year		1-3 Years		3-5 Years		More than 5 Years

Mortgage notes payable (a)	$	884,819	$	16,367	$	147,707	$	263,346	$	457,399

	$	3,424,457	$	201,302	$	1,034,179	$	880,482	$	1,308,494

(a)

Amounts do not include unamortized discounts and/or premiums.

(b)

Future minimum rental payments under the terms of all non-cancelable ground leases under which we are the lessee are expensed on a straight-line basis regardless of when payments are due.

We intend to refinance our mortgage notes payable as they become due or repay those that are secured by properties being sold.

As part of our acquisition of the TRC Properties in September 2004, we agreed to issue to the sellers up to a maximum of $9.7 million of Class A Units of the Operating Partnership if certain of the acquired properties achieve at least 95% occupancy prior to September 21, 2007. The maximum number of Units that we are obligated to issue declines monthly and, as of June 30, 2006, the maximum balance payable under this arrangement was $3.3 million, with no amount currently due.

As part of the TRC acquisition, we acquired our interest in Two Logan Square, a 696,477 square foot office building in Philadelphia, primarily through a second and third mortgage secured by this property. We currently do not expect to take title to Two Logan Square until, at the earliest, September 2019. In the event that we take fee title to Two Logan Square upon a foreclosure of our mortgage, we have agreed to make a payment to an unaffiliated third party with a residual interest in the fee owner of this property. The amount of the payment would be $0.6 million if we must pay a state and local transfer upon taking title, and $2.9 million if no transfer tax is payable upon the transfer.

As part of the Prentiss acquisition, the TRC acquisition and several of our other acquisitions, we agreed not to sell certain of the acquired properties. In the case of the TRC acquisition, we agreed not to sell certain of the acquired properties for periods ranging from three to 15 years from the acquisition date as follows: 201 Radnor Financial Center, 555 Radnor Financial Center and 300 Delaware Avenue (three years); One Rodney Square and 130/150/170 Radnor Financial Center (10 years); and One Logan Square, Two Logan Square and Radnor Corporate Center (15 years). In the case of the Prentiss acquisition, we assumed the obligation of Prentiss not to sell Concord Airport Plaza before March 2018 and 6600 Rockledge before July 2008. We also own 14 other properties that aggregate 1.0 million square feet and have agreed not to sell these properties for periods that expire by the end of 2008. Our agreements generally provide that we may dispose of the subject properties only in transactions that qualify as tax-free exchanges under Section 1031 of the Internal Revenue Code or in other tax deferred transactions. In the event that we sell any of the properties within the applicable restricted period in non-exempt transactions, we would be required to pay significant tax liabilities that would be incurred by the parties who sold us the applicable property.

We hold a fifty percent economic interest in an approximately 141,724 square foot office building located at 101 Paragon Drive, Montvale, New Jersey. The remaining fifty percent interest is held by Donald E. Axinn, one of our Trustees. Although we and Mr. Axinn have each committed to provide one half of the $11 million necessary to repay the mortgage loan secured by this property, in February 2006, an unaffiliated third party entered into an agreement to purchase this property for $18.3 million. Closing is scheduled for the third quarter of 2006 and is subject to standard closing conditions.

We invest in our properties and regularly incur capital expenditures in the ordinary course to maintain the properties. We believe that such expenditures enhance our competitiveness. We also enter into construction, utility and service

contracts in the ordinary course of business which may extend beyond one year. These contracts typically provide for cancellation with insignificant or no cancellation penalties.

Interest Rate Risk and Sensitivity Analysis

The analysis below presents the sensitivity of the market value of our financial instruments to selected changes in market rates. The range of changes chosen reflects our view of changes which are reasonably possible over a one-year period. Market values are the present value of projected future cash flows based on the market rates chosen.

Our financial instruments consist of both fixed and variable rate debt. As of June 30, 2006, our consolidated debt consisted of $913.9 million in fixed rate mortgages and $0.7 million in variable rate mortgage notes, $183.2 million in fixed rate secured note payable, $195.0 million borrowings under our Credit Facility and $1.9 billion in unsecured notes (net of discounts). All financial instruments were entered into for other than trading purposes and the net market value of these financial instruments is referred to as the net financial position. Changes in interest rates have different impacts on the fixed and variable rate portions of our debt portfolio. A change in interest rates on the fixed portion of the debt portfolio impacts the net financial instrument position, but has no impact on interest incurred or cash flows. A change in interest rates on the variable portion of the debt portfolio impacts the interest incurred and cash flows, but does not impact the net financial instrument position.

If market rates of interest on our variable rate debt increase by 1%, the increase in annual interest expense on our variable rate debt would decrease future earnings and cash flows by approximately $5.7 million. If market rates of interest on our variable rate debt decrease by 1%, the decrease in interest expense on our variable rate debt would increase future earnings and cash flows by approximately $5.7 million.

If market rates of interest increase by 1%, the fair value of our outstanding fixed-rate debt would decrease by approximately $94.4 million. If market rates of interest decrease by 1%, the fair value of our outstanding fixed-rate debt would increase by approximately $101.3 million.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Market risk is the exposure to loss resulting from changes in interest rates, commodity prices and equity prices. In pursuing our business plan, the primary market risk to which we are exposed is interest rate risk. Changes in the general level of interest rates prevailing in the financial markets may affect the spread between our yield on invested assets and cost of funds and, in turn, our ability to make distributions or payments to our shareholders. While we have not experienced any significant credit losses, in the event of a significant rising interest rate environment and/or economic downturn, defaults could increase and result in losses to us which adversely affect our operating results and liquidity.

There have been no material changes in Quantitative and Qualitative disclosures in 2006 from the disclosures included in our Annual Report on Form 10-K for the year ended December 31, 2005. Reference is made to Item 7 included in our Annual Report on Form 10-K for the year ended December 31, 2005 and the caption “Interest Rate Risk and Sensitivity Analysis” under Item 2 of this Quarterly Report on Form 10-Q.

Item 4. Controls and Procedures
