During the six months ended June 30, 2011, the Company recorded cash payments of $0.2 million for franchise taxes levied by the city of Washington, D.C. The Company acquired its first property in Washington, D.C. on June 30, 2010 and, therefore was not subject to any Washington, D.C. franchise taxes during the six months ended June 30, 2010.

During the six months ended June 30, 2011, 1,300 Operating Partnership units were redeemed for an equivalent number of the Company’s common shares. No Operating Partnership units were redeemed for an equivalent number of the Company’s common shares during the six months ended June 30, 2010.

During the six months ended June 30, 2011 the Company acquired four consolidated properties at an aggregate purchase price of $189.6 million, including the assumption of $139.4 million of mortgage debt and the issuance of 1,418,715 Operating Partnership units valued at $21.7 million on the date of acquisition. The 2011 acquisitions include 840 First Street, NE, which was acquired for an aggregate purchase price of $90.0 million, with up to $10.0 million of additional consideration payable upon the terms of a lease renewal by the building’s sole tenant or the re-tenanting of the property. At acquisition, the Company was in active negotiations with the existing tenant to renew its lease through August 2023. As a result, the Company recorded a contingent consideration obligation of $9.4 million at acquisition. In July 2011, the building’s sole tenant renewed its lease. Based on the probability of renewal and lease terms used in the original estimate of fair value, the value of contingent consideration remained unchanged.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(1) Description of Business

First Potomac Realty Trust (the “Company”) is a leader in the ownership, management, development and redevelopment of office and industrial properties in the greater Washington, D.C. region. The Company separates its properties into four distinct segments, which it refers to as the Maryland, Washington, D.C., Northern Virginia and Southern Virginia reporting segments. The Company strategically focuses on acquiring and redeveloping properties that it believes can benefit from its intensive property management and seeks to reposition these properties to increase their profitability and value. The Company’s portfolio contains a mix of single-tenant and multi-tenant office and industrial properties as well as business parks. Office properties are single-story and multi-story buildings that are used primarily for office use; business parks contain buildings with office features combined with some industrial property space; and industrial properties generally are used as warehouse, distribution or manufacturing facilities.

References in these unaudited condensed consolidated financial statements to “we,” “our” or “First Potomac,” refer to the Company and its subsidiaries, on a consolidated basis, unless the context indicates otherwise.

The Company conducts its business through First Potomac Realty Investment Limited Partnership, the Company’s operating partnership (the “Operating Partnership”). The Company is the sole general partner of, and, as of June 30, 2011, owned a 95.5% interest in, the Operating Partnership. The remaining interests in the Operating Partnership, which are presented as noncontrolling interests in the Operating Partnership in the accompanying unaudited condensed consolidated financial statements, are limited partnership interests, some of which are owned by several of the Company’s executive officers and trustees who contributed properties and other assets to the Company upon its formation, and other unrelated parties.

At June 30, 2011, the Company wholly-owned or had a controlling interest in properties totaling 13.7 million square feet and had a noncontrolling ownership interest in properties totaling an additional 0.5 million square feet through four unconsolidated joint ventures. The Company also owned land that can accommodate approximately 1.6 million square feet of additional development. The Company derives substantially all of its revenue from leases of space within its properties. As of June 30, 2011, the Company’s largest tenant was the U.S. Government, which along with government contractors, accounted for over 20% of the Company’s total annualized rental revenue. The U.S Government also accounted for approximately a third of the Company’s outstanding accounts receivables at June 30, 2011. The majority of the accounts receivable related to the government was due to the clarification of terms in a specific lease, which has been resolved, and the Company expects to collect the outstanding balance on the specified lease in the third quarter. The Company operates so as to qualify as a real estate investment trust (“REIT”) for federal income tax purposes.

(2) Summary of Significant Accounting Policies

(a) Principles of Consolidation

The unaudited condensed consolidated financial statements of the Company include the accounts of the Company, the Operating Partnership, the subsidiaries of the Operating Partnership in which it has a controlling interest and First Potomac Management LLC, a wholly-owned subsidiary that manages the majority of the Company’s properties. All intercompany balances and transactions have been eliminated in consolidation.

The Company has condensed or omitted certain information and footnote disclosures normally included in financial statements presented in accordance with U.S. generally accepted accounting principles (“GAAP”) in the accompanying unaudited condensed consolidated financial statements. The Company believes the disclosures made are adequate to prevent the information presented from being misleading. However, the unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2010 and as updated from time to time in other filings with the Securities and Exchange Commission.

In the Company’s opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments and accruals necessary to present fairly the Company’s financial position as of June 30, 2011, the results of its operations for the three and six months ended June 30, 2011 and 2010 and its cash flows for the six months ended June 30, 2011 and 2010. Interim results are not necessarily indicative of full-year performance due, in part, to the timing of transactions and the impact of acquisitions and dispositions throughout the year.

7

(b) Use of Estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires management of the Company to make a number of estimates and assumptions relating to the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Estimates include the amount of accounts receivable that may be uncollectible; recoverability of notes receivable, future cash flows, discount and capitalization rate assumptions used to fair value acquired properties and to test impairment of certain long-lived assets and goodwill; market lease rates, lease-up periods, leasing and tenant improvement costs used to fair value intangible assets acquired and probability weighted cash flow analysis used to fair value contingent liabilities. Actual results could differ from those estimates.

(c) Rental Property

Rental property is carried at initial cost less accumulated depreciation and, when appropriate, impairment losses. Improvements and replacements are capitalized at cost when they extend the useful life, increase capacity or improve the efficiency of the asset. Repairs and maintenance are charged to expense when incurred. Depreciation and amortization are recorded on a straight-line basis over the estimated useful lives of the assets. The estimated useful lives of the Company’s assets, by class, are as follows:

Buildings	39 years
Building improvements	5 to 20 years
Furniture, fixtures and equipment	5 to 15 years
Tenant improvements	Shorter of the useful lives of the assets or the terms of the related leases

The Company regularly reviews market conditions for possible impairment of a property’s carrying value. When circumstances such as adverse market conditions, changes in management’s intended holding period or potential sale to a third party indicate a possible impairment of the fair value of a property, an impairment analysis is performed. The Company assesses potential impairments based on an estimate of the future undiscounted cash flows (excluding interest charges) expected to result from the property’s use and eventual disposition. This estimate is based on projections of future revenues, expenses, capital improvement costs, expected holding periods and capitalization rates. These cash flows consider factors such as expected market trends and leasing prospects, as well as the effects of leasing demand, competition and other factors. If impairment exists due to the inability to recover the carrying value of a real estate investment based on forecasted undiscounted cash flows, an impairment loss is recorded to the extent that the carrying value exceeds the estimated fair value of the property. The Company is required to make estimates as to whether there are impairments in the carrying values of its investments in real estate. Further, the Company will record an impairment loss if it expects to dispose of a property, in the near term, at a price below carrying value. In such an event, the Company will record an impairment loss based on the difference between a property’s carrying value and its projected sales price less any estimated costs to sell.

The Company will classify a building as held-for-sale in the period in which it has made the decision to dispose of the building, the Company’s Board of Trustees or a designated delegate has approved the sale, a binding agreement to purchase the property has been signed under which the buyer has committed a significant amount of nonrefundable cash and no significant financing contingencies exist that could cause the transaction not to be completed in a timely manner. The Company will classify any impairment loss, together with the building’s operating results, as discontinued operations in its consolidated statements of operations for all periods presented and classify the assets and related liabilities as held-for-sale in its consolidated balance sheets in the period the sale criteria are met. Interest expense is reclassified to discontinued operations only to the extent the held-for-sale property is secured by specific mortgage debt and the mortgage debt will not be secured to another property owned by the Company after the disposition.

The Company recognizes the fair value, if sufficient information exists to reasonably estimate the fair value, of any liability for conditional asset retirement obligations when incurred, which is generally upon acquisition, construction, development or redevelopment and/or through the normal operation of the asset.

8

The Company capitalizes interest costs incurred on qualifying expenditures for real estate assets under development or redevelopment while being readied for their intended use in accordance with accounting requirements regarding capitalization of interest. The Company will capitalize interest when qualifying expenditures for the asset have been made, activities necessary to get the asset ready for its intended use are in progress and interest costs are being incurred. Capitalized interest also includes interest associated with expenditures incurred to acquire developable land while development activities are in progress and the direct compensation costs of the Company’s construction personnel who manage the development and redevelopment projects, but only to the extent the employee’s time can be allocated to a project. For the three and six months ended June 30, 2011, capitalized compensation costs were immaterial. Capitalization of interest will end when the asset is substantially complete and ready for its intended use, but no later than one year from completion of major construction activity, if the property is not occupied. Capitalized interest is depreciated over the useful life of the underlying assets, commencing when those assets are placed into service.

(d) Notes Receivable

The Company lends money to the owners of real estate properties, which are collateralized by a direct or indirect interest in the real estate property. The Company records these investments as “Notes receivable, net” in its consolidated balance sheets. The investments are recorded net of any discount or issuance costs, which are amortized over the life of the respective note receivable using the effective interest method. The Company records interest received from notes receivable and amortization of any discount or issuance costs within “Interest and other income” in its consolidated statements of operations.

In December 2010, the Company provided a $25.0 million subordinated loan to the owners of 950 F Street, NW, a 287,000 square-foot office building in Washington, D.C., which is secured by a portion of the owners’ interest in the property. The loan has a fixed interest rate of 12.5% and was initially recorded net of $0.3 million of issuance costs. The loan matures on April 1, 2017 and is repayable in full on or after December 21, 2013. For the three and six months ended June 30, 2011, the Company recorded interest income associated with the loan of $0.8 million and $1.6 million, respectively.

In April 2011, the Company provided a $30.0 million subordinated loan to the owners of America’s Square, a 461,000 square-foot office complex in Washington, D.C., which is secured by a portion of the owners’ interest in the property. The loan has a fixed interest rate of 9.0% and was initially recorded net of $0.1 million of issuance costs. The loan matures on May 1, 2016 and is repayable in full on or after October 16, 2012, subject to yield maintenance. For the three and six months ended June 30, 2011, the Company recorded interest income associated with the loan of $0.6 million.

The Company will establish a provision for anticipated credit losses associated with its notes receivables and debt investments when it anticipates that it may be unable to collect any contractually due amounts. This determination is based on upon such factors as delinquencies, loss experience, collateral quality and current economic or borrower conditions. Estimated losses are recorded as a charge to earnings to establish an allowance for credit losses that the Company estimates to be adequate based on these factors. The Company has not recorded any losses associated with its notes receivable during 2011 and 2010.

(e) Reclassifications

Certain prior year amounts have been reclassified to conform to the current year presentation.

(f) Application of New Accounting Standards

In June 2011, new accounting guidance was issued regarding the presentation of other comprehensive income that will eliminate the option of reporting other comprehensive income and its components in the Company’s Statement of Equity. The amendment provides companies the option to present components of net income and comprehensive income as either a single continuous statement or as two separate but consecutive statements. The amendment does not change what items are reported in other comprehensive income or the requirement to report reclassification of items from other comprehensive income to net income. The required disclosures are effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2011. Early adoption is permitted. The Company does not believe the implementation of these disclosures will have a material impact on its consolidated financial statements.

(3) Earnings Per Share

Basic earnings or loss per share (“EPS”) is calculated by dividing net income or loss available to common shareholders by the weighted average common shares outstanding for the period. Diluted EPS is computed after adjusting the basic EPS computation for the effect of dilutive common equivalent shares outstanding during the period, which include stock options, non-vested shares, preferred shares and Exchangeable Senior Notes. The Company applies the two-class method for determining EPS as its outstanding unvested shares with non-forfeitable dividend rights are considered participating securities. The Company’s excess of distributions over earnings related to participating securities are shown as a reduction in total earnings attributable to common shareholders in the Company’s computation of EPS.

15

(b) Unsecured Term Loan

On July 18, 2011, the Company entered into a three-tranche $175.0 million unsecured term loan. The unsecured term loan’s three tranches have maturity dates staggered in one-year intervals. Tranche A has an outstanding balance of $60.0 million at an interest rate of LIBOR plus 215 basis points and matures on July 18, 2016. Tranche B has an outstanding balance of $60.0 million at an interest rate of LIBOR plus 225 basis points and matures on July 18, 2017. Tranche C has an outstanding balance of $55.0 million at an interest rate of LIBOR plus 230 basis points and matures on July 18, 2018. The term loan agreement contains various restrictive covenants substantially similar to those contained in the Company’s revolving credit facility, including with respect to liens, indebtedness, investments, distributions, mergers and asset sales. In addition, the agreement requires that the Company satisfy certain financial covenants that are also substantially similar to those contained in the Company’s revolving credit facility. The agreement also includes customary events of default, the occurrence of which, following any applicable cure period, would permit the lenders to, among other things, declare the principal, accrued interest and other obligations of the Company under the agreement to be immediately due and payable. The Company used the funds to pay down $117.0 million of the outstanding balance on its unsecured revolving credit facility, to repay its $50.0 million senior secured term loan and for other general corporate purposes.

(c) Unsecured Revolving Credit Facility

During the second quarter of 2011, the Company amended and restated its unsecured revolving credit facility. Under the new agreement, the capacity on the Company’s unsecured revolving credit facility was expanded from $225.0 million to $255.0 million and the maturity date was extended to January 2014 with a one-year extension at the Company’s option, which it intends to exercise. The interest rate on the unsecured revolving credit facility decreased from a range of LIBOR plus 275 to 375 basis points to a range of LIBOR plus 200 to 300 basis points, depending on the Company’s overall leverage. At June 30, 2011, LIBOR was 0.19%. The Company’s ability to borrow under the credit facility will be subject to its satisfaction of certain financial covenants and its ongoing compliance with various restrictive covenants similar to those included in the prior credit facility, including with respect to liens, indebtedness, investments, distributions, mergers and asset sales. The credit facility includes customary events of default, the occurrence of which, following any applicable cure period, would permit the lenders to, among other things, declare the principal, accrued interest and other obligations of the Company under the credit facility to be immediately due and payable.

During the second quarter of 2011, the Company borrowed $48.0 million on its unsecured revolving credit facility to provide a subordinated loan to the owners of America’s Square and for general corporate purposes. For the three and six months ended June 30, 2011, the Company’s weighted average borrowings outstanding on its unsecured revolving credit facility was $151.1 million and $132.9 million, respectively, with a weighted average interest rate of 3.1% and 3.2%, respectively, compared with $84.5 million and $117.9 million with a weighted average interest rate of 3.6% and 3.8% for the three and six months ended June 30, 2010, respectively. At June 30, 2011, outstanding borrowings under the unsecured revolving credit facility were $164.0 million. The Company is required to pay an annual commitment fee of 0.25% based on the amount of unused capacity under the unsecured revolving credit facility, which was $91.0 million at June 30, 2011.

(d) Debt Covenants

At June 30, 2011, the Company was in compliance with all of the financial and non-financial covenants associated with its debt instruments with the exception of the mortgage loans explained below.

Certain of the Company’s subsidiaries are borrowers on mortgage loans, the terms of which prohibit certain direct or indirect transfers of ownership interests in the borrower subsidiary (a “Prohibited Transfer”). Under the terms of the mortgage loan documents, a lender could assert that a Prohibited Transfer includes the trading of the Company’s common shares on the NYSE, the issuance of common shares by the Company, or the issuance of units of limited partnership interest in the Operating Partnership. As of June 30, 2011, the Company believes that there were eight mortgage loans with such Prohibited Transfer provisions, representing an aggregate principal amount outstanding of approximately $77 million. Two of these mortgage loans were entered into prior to the Company’s initial public offering (“IPO”) in 2003 and six were assumed subsequent to its IPO. In July 2011, the Company repaid two mortgages totaling $19.7 million with Prohibited Transfer provisions that were both assumed subsequent to its IPO. In each instance, the Company received the consent of the mortgage lender to consummate its IPO (for the two pre-IPO loans) or to acquire the property or the ownership interests of the borrower (for the post-IPO loans), including the assumption by its subsidiary of the mortgage loan. Generally, the underlying mortgage documents, previously applicable to a privately held owner, were not changed at the time of the IPO or the later loan assumptions, although the Company believes that each of the lenders or servicers was aware that the borrower’s ultimate parent was or would become a publicly traded company. Subsequent to the IPO and the assumption of these additional mortgage loans, the Company has issued new common shares and shares of the Company have been transferred on the New York Stock Exchange. Similarly, the Operating Partnership has issued units of limited partnership interest. To date, no lender or servicer has asserted that a Prohibited Transfer has occurred as a result of any such transfer of shares or units of limited partnership interest. If a lender were to be successful in any such action, the Company could be required to immediately repay or refinance the amounts outstanding, or the lender may be able to foreclose on the property securing the loan or take other adverse actions. In addition, in certain cases a Prohibited Transfer could result in the loan becoming fully recourse to the Company or its Operating Partnership. In addition, if a violation of a Prohibited Transfer provision were to occur that would permit the Company’s mortgage lenders to accelerate the indebtedness owed to them, it could result in an event of default under the Company’s Senior Unsecured Series A and Series B Notes, its unsecured revolving credit facility, its senior secured term loan, its two Secured Term Loans and its Exchangeable Senior Notes.

(8) Income Taxes

Beginning in the fourth quarter of 2010, the Company acquired properties located in Washington D.C., which are subject to local franchise taxes. During the three and six months ended June 30, 2011, the Company recognized a benefit for income taxes of $0.1 million and $0.5 million, respectively, related to franchise taxes levied by the city of Washington D.C. at an effective rate of 9.975%. The Company acquired its first property in Washington, D.C. that was subject to franchise tax in the fourth quarter of 2010 and was not subject to any franchise taxes during the three and six months ended June 30, 2010.

The Company recognizes deferred tax assets only to the extent that it is more likely than not that deferred tax assets will be realized based on consideration of available evidence, including future reversals of existing taxable temporary differences, future projected taxable income and tax planning strategies. The Company’s deferred tax assets and liabilities are primarily associated with differences in the GAAP and tax basis of its real estate assets arising from acquisition costs, intangible assets and deferred market rent assets and liabilities that are associated with properties located in Washington D.C. and recorded in its consolidated balance sheets. As of June 30, 2011 and December 31, 2010, the Company recorded its deferred tax assets within “Prepaid expenses and other assets” and recorded its deferred tax liabilities within “Accounts payable and other liabilities” in the Company’s consolidated balance sheets.

The Company has not recorded a valuation allowance against its deferred tax assets as it determined that is more likely than not that future operations will generate sufficient taxable income to realize the deferred tax assets. The Company has not recognized any deferred tax assets or liabilities as a result of uncertain tax positions and has no material net operating loss, capital loss or alternative minimum tax carryovers. There was no (benefit) provision for income taxes associated with the Company’s discontinued operations for any period presented.

As the Company believes it both qualifies as a REIT and will not be subject to federal income tax, a reconciliation between the income tax provision calculated at the statutory federal income tax rate and the actual income tax provision has not been provided.

(9) Derivative Instruments and Comprehensive Income (Loss)

The Company is exposed to certain risks arising from business operations and economic factors. The Company uses derivative financial instruments to manage exposures that arise from business activities in which its future exposure to interest rate fluctuations is unknown. The objective in the use of an interest rate derivative is to add stability to interest expenses and manage exposure to interest rate changes. No hedging activity can completely insulate the Company from the risks associated with changes in interest rates. Moreover, interest rate hedging could fail to protect the Company or adversely affect it because, among other things:

• available interest rate hedging may not correspond directly with the interest rate risk for which the Company seeks protection;

• the duration of the hedge may not match the duration of the related liability;

• the party owing money in the hedging transaction may default on its obligation to pay; and

• the credit quality of the party owing money on the hedge may be downgraded to such an extent that it impairs the Company’s ability to sell or assign its side of the hedging transaction.

The Company enters into interest rate swap agreements to hedge its exposure on its variable rate debt against fluctuations in prevailing interest rates. The interest rate swap agreements fix LIBOR to a specified interest rate, however, the swap agreements do not affect the contractual spreads associated with each variable debt instrument’s applicable interest rate. The table below summarizes the Company’s interest rate swap agreements as of June 30, 2011 (dollars in thousands):

						Interest Rate
						Contractual	Fixed LIBOR
	Transaction Date	Maturity Date	Amount			Component	Interest Rate
Consolidated:	July 2010(1)	January 2014	$	50,000		LIBOR		1.474	%
Unconsolidated:	September 2008	September 2011		28,000	(2)	LIBOR		3.47	%

(1)	The interest rate swap agreement became effective on January 18, 2011.
(2)	The Company remains liable, in the event of default by the joint venture, for $7.0 million, or 25% of the total, which reflects its ownership percentage in the joint venture.

The Company’s interest rate swap agreements are designated as effective cash flow hedges and the Company records any unrealized gains associated with the change in fair value of the swap agreements within equity and “Prepaid expenses and other assets” and any unrealized losses within equity and “Accounts payable and other liabilities.” The Company records its proportionate share of unrealized gains or losses on its cash flow hedges associated with its unconsolidated joint ventures within equity and “Investment in affiliates.”

Total comprehensive income (loss) is summarized as follows (amounts in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,

(10) Fair Value Measurements

The Company adopted accounting provisions that outline a valuation framework and create a fair value hierarchy, which distinguishes between assumptions based on market data (observable inputs) and a reporting entity’s own assumptions about market data (unobservable inputs). The new disclosures increase the consistency and comparability of fair value measurements and the related disclosures. Fair value is identified, under the standard, as the price that would be received to sell an asset or paid to transfer a liability between willing third parties at the measurement date (an exit price). In accordance with GAAP, certain assets and liabilities must be measured at fair value, and the Company provides the necessary disclosures that are required for items measured at fair value as outlined in the accounting requirements regarding fair value.

18

Financial assets and liabilities, as well as those non-financial assets and liabilities requiring fair value measurement, are measured using inputs from three levels of the fair value hierarchy.

The three levels are as follows:

Level 1 — Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. An active market is defined as a market in which transactions for the assets or liabilities occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 — Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active (markets with few transactions), inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.), and inputs derived principally from or corroborated by observable market data correlation or other means (market corroborated inputs).

Level 3 — Unobservable inputs, only used to the extent that observable inputs are not available, reflect the Company’s assumptions about the pricing of an asset or liability.

In accordance with accounting provisions and the fair value hierarchy described above, the following table shows the fair value of the Company’s consolidated assets and liabilities that are measured on a non-recurring and recurring basis as of June 30, 2011 and December 31, 2010 (amounts in thousands):

There were no assets or liabilities measured on a non-recurring basis at June 30, 2011.

Interest Rate Derivatives

On January 18, 2011, the Company fixed LIBOR at 1.474% on $50.0 million of its variable rate debt through an interest rate swap agreement that matures on January 15, 2014. The derivative is fair valued based on prevailing market yield curve on the measurement date. Also, the Company evaluates counter-party risk in calculating the fair value of the interest rate swap derivative instrument. The Company’s interest rate swap derivative is an effective cash flow hedge and any change in fair value is recorded in the Company’s equity section as “Accumulated Other Comprehensive Loss.”

19

The Company uses a third party to assist with the valuation of its interest rate swap agreements. The third party takes a daily “snapshot” of the market to obtain close of business rates. The snapshot includes over 7,500 rates including LIBOR fixings, Eurodollar futures, swap rates, exchange rates, treasuries, etc. This market data is obtained via direct feeds from Bloomberg and Reuters and from Inter-Dealer Brokers. The selected rates are compared to their historical values. Any rate that has changed by more than normal mean and related standard deviation would be considered an outlier and flagged for further investigation. The rates are than compiled through a valuation process that generates daily valuations, which are used to value the Company’s interest rate swap agreements.

A summary of the Company’s interest rate derivatives liability is as follows (amounts in thousands):

	Six months ended
	June 30,
	2011		2010
Balance at December 31,	$	396	$	1,741
Deconsolidation (1)		—		(396	)
Unrealized loss (gain)		392		(1,089	)
Balance at June 30,	$	788	$	256

⁽¹⁾ On January 1, 2010, the Company deconsolidated RiversPark I and all its assets and liabilities, including its interest rate derivative liability, were removed from the Company’s consolidated balance sheets.

The Company recorded an unrealized loss of $0.4 million for the six months ended June 30, 2011 and a unrealized gain of $1.1 million for the six months ended June 30, 2010, related to its derivative liability, which is included in “Accounts payable and other liabilities” in the Company’s consolidated balance sheets.

Contingent Consideration

On March 25, 2011, the Company acquired 840 First Street, NE, in Washington, D.C. for an aggregate purchase price of $90.0 million, with up to $10.0 million of additional consideration payable upon the terms of a lease renewal by the building’s sole tenant or the re-tenanting of the property. At acquisition, the Company was in active negotiations with the existing tenant to renew its lease through August 2023. As a result, the Company recorded a contingent consideration obligation of $9.4 million at acquisition. In July 2011, the building’s sole tenant renewed its lease. Based on the probability of renewal and lease terms used in the original estimate of fair value, the value of contingent consideration remained unchanged. The fair value of the contingent consideration obligation was determined based on several probability weighted discounted cash flow scenarios that projected stabilization being achieved at certain timeframes. The fair value was based, in part, on significant inputs, which are not observable in the market, thus representing a Level 3 measurement in accordance with the fair value hierarchy.

The Company has a contingent consideration obligation associated with the 2009 acquisition of Ashburn Center. As part of the acquisition price of Ashburn Center, the Company entered into a fee agreement with the seller under which the Company will be obligated to pay additional consideration upon the property achieving stabilization per specified terms of the agreement. The Company determines the fair value of the obligation through an income approach based on discounted cash flows that project stabilization being achieved within a certain timeframe. The more significant inputs associated with the fair value determination of the contingent consideration include estimates of capitalization rates, discount rates and various assumptions regarding the property’s operating performance and profitability.

The Company did not recognize any gain or loss associated with its contingent consideration for the three and six months ended June 30, 2011. During the first quarter of 2010, the Company fully leased the Ashburn Center, which resulted in an increase in its potential obligation, and recorded a $0.7 million increase in its contingent consideration to reflect the increase in the Company’s potential obligation with a corresponding entry to “Contingent Consideration Related to Acquisition of Property” in its consolidated statements of operations. The Company has classified its contingent consideration liabilities within “Accounts payable and other liabilities” and any changes in its fair value subsequent to their acquisition date valuation are charged to earnings. There was no significant change in the fair value of the contingent consideration during the quarter ended June 30, 2010.

Impairment of Real Estate Assets

The Company regularly reviews market conditions for possible impairment of a property’s carrying value. When circumstances such as adverse market conditions, changes in management’s intended holding period or potential sale to a third party indicate a possible impairment of a property, an impairment analysis is performed.

For the three months ended June 30, 2011 and 2010, the Company did not record any impairment on its real estate assets. During the first quarter of 2011 and 2010, the Company incurred impairment charges of $2.7 million and $0.6 million, respectively, for properties that were disposed of in the three months ended June 30, 2011 and 2010, respectively.

On December 29, 2010, the Company acquired 7458 Candlewood Road, which is located in the Company’s Maryland reporting segment. Due to the bankruptcy of an acquired tenant, the Company realized an impairment charge of $2.4 million to reflect the fair value of the intangible asset associated with the tenant’s lease, which was determined to have no value. The non-recoverable value of the intangible assets was based on, among other items, an analysis of current market rates, the present value of future cash flows that were discounted using capitalization rates, lease renewal probabilities, hypothetical leasing timeframes, historical leasing commissions, expected value of tenant improvements and recently executed leases.

In September 2010, the Company adjusted its anticipated holding period for its Old Courthouse Square property, which is located in the Company’s Maryland reporting segment. The Company entered into a non-binding contract to sell the asset in October 2010. As a result, the Company realized a $3.4 million impairment charge to reduce the property’s carrying value to reflect its fair value, less any potential selling costs. The property was sold on February 18, 2011 for net proceeds of $10.8 million. The Company determined the fair value of the property through an assessment of market data in working with a real estate broker on the transaction and based on the execution of a non-binding letter of intent. The fair value was further validated through an income approach based on discounted cash flows that reflected a reduced holding period.

With the exception of its contingent consideration obligation, the Company did not re-measure or complete any transactions involving non-financial assets or non-financial liabilities that are measured on a recurring basis during the six months ended June 30, 2011. Also, no transfers into and out of fair value measurements levels occurred during the six months ended June 30, 2011 or 2010.

Financial Instruments

The carrying amounts of cash equivalents, accounts and other receivables and accounts payable, with the exception of any items listed above, approximate their fair values due to their short-term maturities. The Company uses third parties with mezzanine lending expertise to value its notes receivable based on comparable deals, market analysis and underlying asset operating results. The Company calculates the fair value of its debt instruments by discounting future contractual principal and interest payments using prevailing market rates for securities with similar terms and characteristics at the balance sheet date. The carrying amount and estimated fair value of the Company’s note receivables and debt instruments at June 30, 2011 and December 31, 2010 are as follows (amounts in thousands):

	June 30, 2011				December 31, 2010

(2)	The face value of the notes was $30.4 million at June 30, 2011 and December 31, 2010.

(11) Equity

On May 13, 2011, the Company paid a dividend of $0.20 per share to common shareholders of record as of May 6, 2011 and paid a dividend of $0.484375 per share to preferred shareholders of record as of May 6, 2011. On July 25, 2011, the Company declared a dividend of $0.20 per common share, which is payable on August 12, 2011 to common shareholders of record as of August 5, 2011. On July 25, 2011, the Company also declared a dividend of $0.484375 per share on its Series A Preferred Shares, which is payable on August 15, 2011 to preferred shareholders of record as of August 5, 2011. Dividends on all non-vested share awards are recorded as a reduction of shareholders’ equity.

(12) Noncontrolling Interests in Partnerships

(a) Noncontrolling Interests in Operating Partnership

Noncontrolling interests relate to the interests in the Operating Partnership not owned by the Company. Interests in the Operating Partnership are owned by limited partners who contributed buildings and other assets to the Operating Partnership in exchange for Operating Partnership units. Limited partners have the right to tender their units for redemption in exchange for, at the Company’s option, common shares of the Company on a one-for-one basis or cash based on the fair value of the Company’s common shares at the date of redemption. Unitholders receive a distribution per unit equivalent to the dividend per common share. Differences between amounts paid to redeem noncontrolling interests and their carrying values are charged or credited to equity. As a result of the redemption feature of the Operating Partnership units, the noncontrolling interests are recorded outside of permanent equity. Noncontrolling interests are presented at the greater of their fair value or their cost basis, which is comprised of their fair value at issuance, subsequently adjusted for the noncontrolling interests’ share of net income, losses, distributions received, preferred dividends paid or additional contributions. Based on the closing share price of the Company’s common stock at June 30, 2011, the cost to acquire, through cash purchase or issuance of the Company’s common shares, all of the outstanding Operating Partnership units not owned by the Company would be approximately $36.4 million, which exceeded the noncontrolling interests’ historical cost by $3.2 million.

At December 31, 2010, 958,473 Operating Partnership units, or 1.9%, were not owned by the Company. During the six months ended June 30, 2011, the Company issued 1,418,715 Operating Partnership units valued at $21.7 million to partially fund the acquisition of 840 First Street, NE. There were also 1,300 Operating Partnership units redeemed for 1,300 common shares fair valued at $19 thousand. As a result, 2,375,888 of the total outstanding Operating Partnership units, or 4.5%, were not owned by the Company at June 30, 2011. There were no Operating Partnership units redeemed with available cash during the six months ended June 30, 2011.

(b) Noncontrolling Interests in Consolidated Partnerships

When the Company is deemed to have a controlling interest in a partially-owned entity, it will consolidate all of the entity’s assets, liabilities and operating results within its consolidated financial statements. The cash contributed to the consolidated entity by the third party, if any, will be reflected in the permanent equity section of the Company’s consolidated balance sheets to the extent they are not mandatorily redeemable. The amount will be recorded based on the third party’s initial investment in the consolidated entity and will be adjusted to reflect the third party’s share of earnings or losses in the consolidated entity and for any distributions received or additional contributions made by the third party. The earnings or losses from the entity attributable to the third party are recorded as a component of net loss (income) attributable to noncontrolling interests.

On November 10, 2010, the Company acquired Redland Corporate Center II and III through a joint venture with Perseus Realty, LLC (“Perseus”). As a result of the partnership structure, the Company has a 97% economic interest in the joint venture and Perseus has the remaining 3% interest. As of June 30, 2011, the Company recorded noncontrolling interests of $3.1 million, which reflects the third party’s common equity interest in Redland Corporate Center II & III.

23

On January 25, 2011, the Company formed a joint venture with an affiliate of The Akridge Company (“Akridge”) to acquire, for $39.6 million, a property located at 1200 17th Street, NW, in Washington, DC, and to redevelop the property. The property currently consists of a land parcel that contains an existing 85,000 square foot office building. The joint venture intends to demolish the existing building and develop a new Class A office building expected to have approximately 170,000 square feet of gross leasable area. When the joint venture is fully capitalized, the Company anticipates owning 95% of the joint venture (subject to adjustment depending on each party’s capital contributions and subject to a promoted interest granted to Akridge after specified returns are achieved by the Company). The Company’s total capital commitment to the joint venture (including acquisition and development costs) is anticipated to be approximately $109 million, less amounts funded through acquisition and construction financing. The acquisition of the property is not expected to occur until late 2011 and is subject to various contingencies. Construction is currently expected to commence in 2012 and is expected to be completed in late 2014. As of June 30, 2011, the Company recorded noncontrolling interests of $1.0 million, which reflects the third party’s common equity interest in 1200 17th Street, NW.

(13) Share-Based Compensation

The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The expense associated with the share based awards will be recognized over the period during which an employee is required to provide services in exchange for the award — the requisite service period (usually the vesting period). The fair value for all share-based payment transactions are recognized as a component of income from continuing operations.

Option Exercises

The Company received approximately $46 thousand and $7 thousand from the exercise of stock options during the three months ended June 30, 2011 and 2010, respectively, and $64 thousand and $16 thousand for the six months ended June 30, 2011 and 2010, respectively. Shares issued as a result of stock option exercises are funded through the issuance of new shares. The total intrinsic value of options exercised during the three months ended June 30, 2011 and 2010 were $25 thousand and $5 thousand, respectively, and $34 thousand and $9 thousand for the six months ended June 30, 2011 and 2010, respectively.

Non-vested share awards

On May 19, 2011, the Company issued a total of 20,310 restricted share awards to its non-employee trustees, all of which will vest on the first anniversary of the award date. The trustee shares were fair valued based on the share price of the underlying common shares on the date of issuance.

The Company recognized compensation expense associated with its restricted share awards of $0.6 million and $0.9 million for the three months ended June 30, 2011 and 2010, respectively, and $1.2 million and $1.9 million for the six months ended June 30, 2011 and 2010, respectively. Dividends on all restricted share awards are recorded as a reduction of equity. The Company applies the two-class method for determining EPS as its outstanding unvested shares with non-forfeitable dividend rights are considered participating securities. The Company’s excess of distributions over earnings related to participating securities are shown as a reduction in net income available to common shareholders in the Company’s computation of EPS.

A summary of the Company’s non-vested share awards as of June 30, 2011 is as follows:

				Weighted
	Non-vested			Average Grant
	Shares			Date Fair Value
Non-vested at March 31, 2011		782,433		$	12.70
Granted		20,310			16.25
Vested		(53,775	)		14.58
Non-vested at June 30, 2011		748,968			12.66

A summary of non-vested share awards and activity for the period ended March 31, 2011 is discussed in the Company’s first quarter 2011 Form 10-Q.

As of June 30, 2011, the Company had $4.7 million of unrecognized compensation cost related to non-vested shares. The Company anticipates this cost will be recognized over a weighted-average period of 3.3 years.

(14) Segment Information

The Company’s reportable segments consist of four distinct reporting and operational segments within the greater Washington D.C, region in which it operates: Maryland, Washington, D.C., Northern Virginia and Southern Virginia. Prior to 2011, the Company had reported its properties located in Washington, D.C. within its Northern Virginia reporting segment. However, due to the Company’s growth within the Washington, D.C. region, it has altered its internal structure, which includes changing the Company’s internal decision making process regarding its Washington, D.C. properties. Therefore, the Company feels it is appropriate to separate the properties owned in Washington, D.C. into its own reporting segment.

The Company evaluates the performance of its segments based on the operating results of the properties located within each segment, which excludes large non-recurring gains and losses, gains from sale of real estate assets, interest expense, general and administrative costs, acquisition costs or any other indirect corporate expense to the segments. In addition, the segments do not have significant non-cash items other than straight-line and deferred market rent amortization reported in their operating results. There are no inter-segment sales or transfers recorded between segments.

(15) Subsequent Events

On July 19, 2011, the Company acquired Greenbrier Towers I & II in Chesapeake, Virginia for a contractual price of $16.7 million. The property consists of two office buildings totaling 172,000 square feet and is 86% leased to over 40 tenants. The acquisition was funded with proceeds from the sale of Aquia Commerce Center I & II and a draw on the Company’s line of credit.

On August 4, 2011, the Company formed a joint venture with Perseus Realty, LLC to acquire the Greyhound Bus Terminal site at 1005 First Street, NE for $46.8 million, of which, $38.4 million was paid at closing and the remaining $8.4 million will be paid in August 2013. The joint venture intends on developing the 1.6 acre site that can accommodate development of up to approximately 712,000 square feet of office space. The site is currently occupied by the Greyhound Bus Terminal, which will lease back the site under a ten-year lease agreement with a termination option after the second lease year. Greyhound has already announced that it intends to relocate to nearby Union Station. The Company estimates a 6.5% return from the lease-back while development is being planned. When the joint venture is fully capitalized, the Company anticipates owning 97% of the joint venture.

ITEM 2: MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of the Company’s financial condition and results of operations should be read in conjunction with the condensed consolidated financial statements and notes thereto appearing elsewhere in this Form 10-Q. The discussion and analysis is derived from the consolidated operating results and activities of First Potomac Realty Trust.

First Potomac Realty Trust (the “Company”) is a leader in the ownership, management, development and redevelopment of office and industrial properties in the greater Washington, D.C. region. The Company separates its properties into four distinct segments, which it refers to as the Maryland, Washington, D.C., Northern Virginia and Southern Virginia reporting segments. The Company strategically focuses on acquiring and redeveloping properties that it believes can benefit from its intensive property management and seeks to reposition these properties to increase their profitability and value. The Company’s portfolio contains a mix of single-tenant and multi-tenant office and industrial properties as well as business parks. Office properties are single-story and multi-story buildings that are used primarily for office use; business parks contain buildings with office features combined with some industrial property space; and industrial properties generally are used as warehouse, distribution or manufacturing facilities.

References in these unaudited condensed consolidated financial statements to “we,” “our” or “First Potomac,” refer to the Company and its subsidiaries, on a consolidated basis, unless the context indicates otherwise.

The Company conducts its business through First Potomac Realty Investment Limited Partnership; the Company’s operating partnership (the “Operating Partnership”). The Company is the sole general partner of, and, as of June 30, 2011, owned a 95.5% interest in, the Operating Partnership. The remaining interests in the Operating Partnership, which are presented as noncontrolling interests in the Operating Partnership in the accompanying unaudited condensed consolidated financial statements, are limited partnership interests, some of which are owned by several of the Company’s executive officers and trustees who contributed properties and other assets to the Company upon its formation, and other unrelated parties.

At June 30, 2011, the Company wholly-owned or had a controlling interest in properties totaling 13.7 million square feet and had a noncontrolling ownership interest in properties totaling an additional 0.5 million square feet through four unconsolidated joint ventures. The Company also owned land that can accommodate approximately 1.6 million square feet of additional development. The Company derives substantially all of its revenue from leases of space within its properties. As of June 30, 2011, the Company’s largest tenant was the U.S. Government, which along with government contractors, accounted for over 20% of the Company’s total annualized rental revenue. The U.S Government also accounted for approximately a third of the Company’s outstanding accounts receivables at June 30, 2011. The majority of the accounts receivable related to the government was due to the clarification of terms in a specific lease, which has been resolved, and the Company expects to collect the outstanding balance of the specified lease in the third quarter. The Company operates so as to qualify as a real estate investment trust (“REIT”) for federal income tax purposes.

The primary source of the Company’s revenue and earnings is rent received from customers under long-term (generally three to ten years) operating leases at its properties, including reimbursements from customers for certain operating costs. Additionally, the Company may generate earnings from the sale of assets either outright or contributed into joint ventures.

The Company’s long-term growth will principally be driven by its ability to:

• maintain and increase occupancy rates and/or increase rental rates at its properties;

• sell assets to third parties at favorable prices or contribute properties to joint ventures; and

• continue to grow its portfolio through acquisition of new properties, potentially through joint ventures.

Executive Summary

The Company had net income of $0.8 million during the second quarter of 2011 compared with net income of $33 thousand during the second quarter of 2010. The increase in the Company’s net income for the quarter ended June 30, 2011 compared with 2010 is primarily due to an increase in gain on sale of real estate properties. The Company sold a property in the second quarter of 2011 for a gain of $2.0 million compared with a gain of $0.6 million from a property sold in the second quarter of 2010. The increase in net income for the three months ended June 30, 2011 was partially offset by an increase in interest expense as the Company issued additional debt and assumed several mortgages in its acquisition of properties in the fourth quarter of 2010 and the first half of 2011.

28

For the six months ended June 30, 2011, the Company incurred a net loss of $3.1 million compared with a net loss of $2.2 million during the six months ended June 30, 2010. The increase in the Company’s net loss for the six months ended June 30, 2011 compared with the same period in 2010 is primarily due to an increase in acquisition costs and impairment charges. The Company acquired four properties during the six months ended June 30, 2011, incurring $2.7 million in acquisition costs, compared with two property acquisitions during the six months ended June 30, 2010, incurring $1.7 million in acquisition costs. During the first quarter of 2011, the Company incurred a $2.7 million impairment charge on a property in its Maryland region that was sold in the second quarter of 2011. During the first quarter of 2010, the Company incurred a $0.6 impairment charge on a property in its Maryland region that was sold in the second quarter of 2010.

The Company’s funds from operations (“FFO”) were $14.0 million, or $0.27 per diluted share, and $21.7 million, or $0.42 per diluted share, for the three and six months ended June 30, 2011, respectively, compared with FFO of $10.2 million, or $0.27 per diluted share, and $18.2 million, or $0.53 per diluted share, for the three and six months ended June 30, 2010, respectively. The increase in FFO for the periods presented is primarily due to an increase in the Company’s net operating income. FFO is a non-GAAP financial measure. For a description of FFO, including why management believes its presentation is useful and a reconciliation of FFO to net income (loss) attributable to First Potomac Realty Trust, see “Funds From Operations.”

Significant Second Quarter Transactions

• Executed 740,000 square feet of leases; 232,000 square feet of which were new leases.

• Expanded borrowing capacity of unsecured revolving credit facility from $225 to $255 million;

• Acquired a property in the Company’s Northern Virginia reporting segment for an aggregate purchase price of $58 million, which had an anticipated capitalization rate of 8.8%;

• Sold Aquia Commerce Center I & II for net proceeds of $11.3 million, which equated to an 8.7% capitalization rate, and sold Gateway West for net proceeds of $4.8 million, which equated to a 3.8% capitalization rate as the property was largely vacant at the time of sale. The Company calculates the capitalization rates associated with its disposed properties as the property’s annualized net operating income divided by the selling cost of the property.

Development and Redevelopment Activity

As of June 30, 2011, the Company continued development of several parcels of land, including land adjacent to previously acquired properties and land acquired with the intent to develop. The Company constructs office, business parks and/or industrial buildings on a build-to-suit basis or with the intent to lease upon completion of construction. Also, the Company expects to continue redevelopment efforts on unfinished vacant spaces in its portfolio through the investment of capital in electrical, plumbing and other capital improvements in order to expedite the leasing of the spaces.

Below is a summary of the approximate building square footage that can be developed on the Company’s developable land and the Company’s current development and redevelopment activity (amounts in thousands):

The majority of the development and redevelopment costs incurred through the Company’s ongoing projects have taken place at Three Flint Hill in the Company’s Northern Virginia region. Three Flint Hill is a 174,000 square foot, eight-story Class A office building. The Company has incurred approximately $9.9 million in redevelopment costs, which include architectural, and engineering design fees and permit fees as well as demolition, glass, HVAC, electrical, plumbing, and lobby finish work.

Lease Expirations

Approximately 15% of the Company’s annualized base rent is scheduled to expire in the remainder of 2011 and 2012, excluding month-to-month leases. Current tenants may not renew their leases upon the expiration of their terms. If non-renewals or terminations occur, the Company may not be able to locate qualified replacement tenants and, as a result, could lose a significant source of revenue while remaining responsible for the payment of its financial obligations. Moreover, the terms of a renewal or new lease, including the amount of rent, may be less favorable to the Company than the current lease terms, or the Company may be forced to provide tenant improvements at its expense or provide other concessions or additional services to maintain or attract tenants. We continually strive to increase our portfolio occupancy, and the amount of vacant space in our portfolio at any given time may impact our willingness to reduce rental rates or provide greater concessions to retain existing tenants and attract new tenants. The Company’s management continually monitors its portfolio on a regional and per property basis to assess market trends, including vacancy, comparable deals and transactions, and other business and economic factors that may influence our leasing decisions. During the three months ended June 30, 2011, the Company had a 71% retention rate, based on square footage. The weighted average rental rate on the Company’s renewed leases decreased 0.1% compared with the expiring leases.

Critical Accounting Policies and Estimates

The Company’s condensed consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) that require the Company to make certain estimates and assumptions. Critical accounting policies and estimates are those that require subjective or complex judgments and are the policies and estimates that the Company deems most important to the portrayal of its financial condition and results of operations. It is possible that the use of different reasonable estimates or assumptions in making these judgments could result in materially different amounts being reported in its condensed consolidated financial statements. The Company’s critical accounting policies relate to revenue recognition, including evaluation of the collectability of accounts receivable, impairment of long-lived assets, purchase accounting for acquisitions of real estate, derivative instruments and share-based compensation.

The following is a summary of certain aspects of these critical accounting policies and estimates.

Revenue Recognition

The Company generates substantially all of its revenue from leases on its office and industrial properties as well as business parks. The Company recognizes rental revenue on a straight-line basis over the term of its leases, which includes fixed-rate renewal periods leased at below market rates at acquisition or inception. Accrued straight-line rents represent the difference between rental revenue recognized on a straight-line basis over the term of the respective lease agreements and the rental payments contractually due for leases that contain abatement or fixed periodic increases. The Company considers current information, credit quality, historical trends, economic conditions and other events regarding the tenants’ ability to pay their obligations in determining if amounts due from tenants, including accrued straight-line rents, are ultimately collectible. The uncollectible portion of the amounts due from tenants, including accrued straight-line rents, is charged to property operating expense in the period in which the determination is made.

35

Tenant leases generally contain provisions under which the tenants reimburse the Company for a portion of property operating expenses and real estate taxes incurred by the Company. Such reimbursements are recognized in the period in which the expenses are incurred. The Company records a provision for losses on estimated uncollectible accounts receivable based on its analysis of risk of loss on specific accounts. Lease termination fees are recognized on the date of termination when the related lease or portion thereof is cancelled, the collectability of the fee is reasonably assured and the Company has possession of the terminated space.

Accounts and Notes Receivable

The Company must make estimates of the collectability of its accounts and notes receivable related to minimum rent, deferred rent, tenant reimbursements, lease termination fees and interest and other income. The Company specifically analyzes accounts and notes receivable and historical bad debt experience, tenant concentrations, tenant creditworthiness and current economic trends when evaluating the adequacy of its allowance for doubtful accounts receivable. These estimates have a direct impact on the Company’s net income as a higher required allowance for doubtful accounts receivable will result in lower net income. The uncollectible portion of the amounts due from tenants, including straight-line rents, is charged to property operating expense in the period in which the determination is made.

Investments in Real Estate and Real Estate Entities

Investments in real estate are initially recorded at fair value and carried at initial cost, less accumulated depreciation and, when appropriate, impairment losses. Improvements and replacements are capitalized at fair value when they extend the useful life, increase capacity, or improve the efficiency of the asset. Repairs and maintenance are charged to expense when incurred.

Depreciation and amortization are recorded on a straight-line basis over the estimated useful lives of the assets. The estimated useful lives of the Company’s assets, by class, are as follows:

Buildings	39 years
Building improvements	5 to 20 years
Furniture, fixtures and equipment	5 to 15 years
Tenant improvements	Shorter of the useful lives of the assets or the terms of the related leases
Lease related intangible assets	Term of related lease

The Company regularly reviews market conditions for possible impairment of a property’s carrying value. When circumstances such as adverse market conditions, changes in management’s intended holding period or potential sale to a third party indicate a possible impairment of the fair value of a property, an impairment analysis is performed. The Company assesses potential impairments based on an estimate of the future undiscounted cash flows (excluding interest charges) expected to result from the property’s use and eventual disposition. This estimate is based on projections of future revenues, expenses, capital improvement costs, expected holding periods and capitalization rates. These cash flows consider factors such as expected market trends and leasing prospects, as well as the effects of leasing demand, competition and other factors. If impairment exists due to the inability to recover the carrying value of a real estate investment based on forecasted undiscounted cash flows, an impairment loss is recorded to the extent that the carrying value exceeds the estimated fair value of the property. The Company is required to make estimates as to whether there are impairments in the carrying values of its investments in real estate. Further, the Company will record an impairment loss if it expects to dispose of a property, in the near term, at a price below carrying value. In such an event, the Company will record an impairment loss based on the difference between a property’s carrying value and its projected sales price, less any estimated costs to sell.

The Company will classify a building as held-for-sale in the period in which it has made the decision to dispose of the building, a binding agreement to purchase the property has been signed under which the buyer has committed a significant amount of nonrefundable cash and no significant financing contingencies exist that could cause the transaction not to be completed in a timely manner. The Company will classify any impairment loss, together with the building’s operating results, as discontinued operations in its consolidated statements of operations for all periods presented and classify the assets and related liabilities as held-for-sale in its consolidated balance sheets in the period the sale criteria are met. Interest expense is reclassified to discontinued operations only to the extent the held-for-sale property is secured by specific mortgage debt and the mortgage debt will not be transferred to another property owned by the Company after the disposition.

The Company recognizes the fair value, if sufficient information exists to reasonably estimate the fair value, of any liability for conditional asset retirement obligations when incurred, which is generally upon acquisition, construction, development or redevelopment and/or through the normal operation of the asset.

36

The Company capitalizes interest costs incurred on qualifying expenditures for real estate assets under development or redevelopment while being readied for their intended use in accordance with accounting requirements regarding capitalization of interest. The Company will capitalize interest when qualifying expenditures for the asset have been made, activities necessary to get the asset ready for its intended use are in progress and interest costs are being incurred. Capitalized interest also includes interest associated with expenditures incurred to acquire developable land while development activities are in progress and interest on the direct compensation costs of the Company’s construction personnel who manage the development and redevelopment projects, but only to the extent the employee’s time can be allocated to a project. For the three and six months ended June 30, 2011, capitalized compensation costs were immaterial. Capitalization of interest will end when the asset is substantially complete and ready for its intended use, but no later than one year from completion of major construction activity, if the property is not occupied. Capitalized interest is depreciated over the useful life of the underlying assets, commencing when those assets are placed into service.

Purchase Accounting

Acquisitions of rental property from third parties are accounted for at fair value. Any liabilities assumed or incurred are recorded at their fair value at the time of acquisition. The fair value of the acquired property is allocated between land and building (on an as-if vacant basis) based on management’s estimate of the fair value of those components for each type of property and to tenant improvements based on the depreciated replacement cost of the tenant improvements, which approximates their fair value. The fair value of the in-place leases is recorded as follows:

• the fair value of leases in-place on the date of acquisition is based on absorption costs for the estimated lease-up period in which vacancy and foregone revenue are avoided due to the presence of the acquired leases;

• the fair value of above and below-market in-place leases based on the present value (using a discount rate that reflects the risks associated with the acquired leases) of the difference between the contractual rent amounts to be paid under the assumed lease and the estimated market lease rates for the corresponding spaces over the remaining non-cancelable terms of the related leases, which range from one to fifteen years; and

• the fair value of intangible tenant or customer relationships.

The Company’s determination of these fair values requires it to estimate market rents for each of the leases and make certain other assumptions. These estimates and assumptions affect the rental revenue, and depreciation and amortization expense recognized for these leases and associated intangible assets and liabilities.

Derivative Instruments

In the normal course of business, the Company is exposed to the effect of interest rate changes. The Company may enter into derivative agreements to mitigate exposure to unexpected changes in interest rates and may use interest rate protection or cap agreements to reduce the impact of interest rate changes. The Company does not use derivatives for trading or speculative purposes and intends to enter into derivative agreements only with counterparties that it believes have a strong credit rating to mitigate the risk of counterparty default or insolvency.

The Company may designate a derivative as either a hedge of the cash flows from a debt instrument or anticipated transaction (cash flow hedge) or a hedge of the fair value of a debt instrument (fair value hedge). All derivatives are recognized as assets or liabilities at fair value. For effective hedging relationships, the change in the fair value of the assets or liabilities is recorded within equity (cash flow hedge), or through earnings (fair value hedge). Ineffective portions of derivative transactions will result in changes in fair value recognized in earnings. The Company records its proportionate share of unrealized gains or losses on its derivative instruments associated with its unconsolidated joint ventures within equity and “Investment in affiliates.” The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting any applicable credit enhancements, such as collateral postings, thresholds, mutual inputs and guarantees.

37

Share-Based Compensation

The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. For options awards, the Company uses a Black-Scholes option-pricing model. Expected volatility is based on an assessment of the Company’s realized volatility over the preceding five years, which is equivalent to the awards expected life. The expected term represents the period of time the options are anticipated to remain outstanding as well as the Company’s historical experience for groupings of employees that have similar behavior and considered separately for valuation purposes. For non-vested share awards that vest over a predetermined time period, the Company uses the outstanding share price at the date of issuance to fair value the awards. For non-vested shares awards that vest based on performance conditions, the Company uses a Monte Carlo simulation (risk-neutral approach) to determine the value and derived service period of each tranche. The expense associated with the share based awards will be recognized over the period during which an employee is required to provide services in exchange for the award — the requisite service period (usually the vesting period). The fair value for all share-based payment transactions are recognized as a component of income from continuing operations.

Results of Operations

Comparison of the Three and Six Months Ended June 30, 2011 with the Three and Six Months Ended June 30, 2010

Rental Revenue

Rental revenue is comprised of contractual rent, the impact of straight-line revenue and the amortization of deferred market rent assets and liabilities representing above and below market rate leases at acquisition. Rental revenue increased $8.4 million and $13.8 million for the three and six months ended June 30, 2011, respectively, compared with the same periods in 2010, which was primarily due to increased revenues from the Company’s recent acquisitions. The Non-comparable Properties contributed $8.8 million and $14.1 million of additional rental revenue for the three and six months ended June 30, 2011, respectively. Rental revenue for the Comparable Portfolio decreased $0.4 million and $0.3 million for the three and six months ended June 30, 2011, respectively, compared with the same periods in 2010, due to an increase in vacancy. The weighted average occupancy of the Comparable Portfolio was 83.0% for the quarter ended June 30, 2011 compared with 84.1% for the same period in 2010. During the three months ended June 30, 2011, the Company signed 53 new and renewal leases, of which, 33 leases, or 62%, contained fixed rate rental increases ranging from 2.5% to 3.26%. The Company expects aggregate rental revenues will increase throughout 2011 due to a full-year of revenues from the properties acquired in 2010 and additional properties acquired in 2011.

The increase in rental revenue for the three and six months ended June 30, 2011 compared with 2010 includes $2.0 million and $4.2 million, respectively, for the Maryland reporting segment, $4.5 million and $7.3 million, respectively, for the Washington, D.C. reporting segment, $1.8 million and $2.0 million, respectively, for the Northern Virginia reporting segment and $0.1 million and $0.3 million, respectively, for the Southern Virginia reporting segment.

38

Tenant Reimbursements and Other Revenues

Tenant reimbursements and other revenues include operating and common area maintenance costs reimbursed by the Company’s tenants as well as other incidental revenues such as lease termination payments, construction management fees and late fees. Tenant reimbursements and other revenues increased $1.9 million and $2.2 million during the three and six months ended June 30, 2011, respectively, compared with the same periods in 2010. The increase is due to the Non-comparable Properties, which contributed $2.3 million and $3.4 million of additional tenant reimbursements and other revenues for the three and six months ended June 30, 2011, respectively, compared with the same periods in 2010. For the Comparable Portfolio, tenant reimbursements and other revenues decreased $0.4 million and $1.2 million for the three and six months ended June 30, 2011, respectively, compared with the same periods in 2010 primarily due to a reduction in termination fee income. The Company expects tenant reimbursements and other revenues to increase throughout 2011 due to a full-year of recoverable operating expenses from properties acquired in 2010 and additional properties acquired in 2011.

The increase in tenant reimbursements and other revenues for the three and six months ended June 30, 2011 compared with 2010 include $1.4 million and $2.2 million, respectively, for the Washington, D.C. reporting segment, $0.6 million and $0.2 million, respectively, for the Northern Virginia reporting segment and $0.2 million and $0.1 million, respectively, for the Southern Virginia reporting segment. For the Maryland reporting segment, tenant reimbursements and other revenues decreased $0.3 million for both the three and six months ended June 30, 2011 compared with the same periods in 2010.

Real estate taxes and insurance	$	4,091	$	3,131	$	8,032	$	6,392	$	960		31	%	$	1,640		26	%

Property operating expenses increased $2.7 million and $3.7 million for the three and six months ended June 30, 2011, respectively, compared with the same periods in 2010. The increase is due to the Non-comparable Properties, which contributed $2.8 million and $4.7 million of additional property operating expenses for the three and six months ended June 30, 2011, respectively. For the Comparable Portfolio, property operating expenses decreased $0.1 million for the three months ended June 30, 2011, which was primarily due to a decline in reserves for bad debt expense, and decreased $1.0 million for the six months ended June 30, 2011 due to a decline in snow and ice removal costs. The Company expects property operating expenses to increase for the remainder of the year compared with prior year results due primarily to the Company’s new acquisitions. The increase in property operating expenses for the three and six months ended June 30, 2011 compared with 2010 includes $0.7 million and $1.2 million, respectively, for the Maryland reporting segment, $1.1 million and $1.9 million, respectively, for the Washington, D.C. reporting segment and $0.7 million and $0.6 million, respectively, for the Northern Virginia reporting segment. For the Southern Virginia reporting segment, property operating expenses increased $0.2 million for the three months ended June 30, 2011 compared with the same period in 2010 and remained flat for the six months ended June 30, 2011 compared to 2010.

Real estate taxes and insurance expense increased $1.0 million and $1.6 million for the three and six months ended June 30, 2011, respectively, compared with the same periods in 2010. The Non-comparable Properties contributed an increase in real estate taxes and insurance expense of $1.2 million and $2.1 million for the three and six months ended June 30, 2011, respectively. For the Comparable Portfolio, real estate taxes and insurance expense decreased $0.2 million and $0.5 million for the three and six months ended June 30, 2011, respectively, compared with the same periods in 2010 primarily due to lower real estate assessments and real estate tax rates. Real estate taxes and insurance expense for the three and six months ended June 30, 2011 compared with 2010, increased $0.2 million and $0.3 million, respectively, for the Maryland reporting segment, $0.8 million and $1.2 million, respectively, for the Washington, D.C. reporting segment and $0.1 million and $0.2 million, respectively, for the Northern Virginia reporting segment. For the Southern Virginia reporting segment, real estate taxes and insurance expense decreased $0.1 million for both the three and six months ended June 30, 2011 compared to 2010.

Acquisition costs decreased $1.1 million for the three months ended June 30, 2011 compared with the same period in 2010 and increased $1.1 million for the six months ended June 30, 2011 compared with the same period in 2010. During 2011, the Company acquired three properties in the first quarter and one property in the second quarter compared with 2010 when the Company acquired two properties in the second quarter.

Depreciation and amortization expenses are summarized as follows:

	Three Months Ended				Six Months Ended				Three Months					Six Months
	June 30,				June 30,						Percent					Percent

Depreciation and amortization expense includes depreciation of real estate assets and amortization of intangible assets and leasing commissions. Depreciation and amortization expense increased $6.5 million and $9.4 million for the three and six months ended June 30, 2011, respectively, compared with the same periods in 2010 primarily due to the Company’s recent acquisitions. The Non-comparable Properties contributed additional depreciation and amortization expense of $6.2 million and $8.6 million for the three and six months ended June 30, 2011, respectively. The additional increase in depreciation and amortization expense was attributed to the Comparable Portfolio, which contributed additional depreciation and amortization expense of $0.3 million and $0.8 million for the three and six months ended June 30, 2011, respectively, compared with the same periods in 2010, primarily due to the disposal of assets from tenants that vacated during the year prior to reaching the full term of their lease. The Company anticipates depreciation and amortization expense to increase the remainder of 2011 due to recognizing a full-year of depreciation and amortization expense for properties acquired in 2010 and additional properties acquired in 2011.

	$	—	$	—	$	—	$	710	$	—		—	$	710		100	%

As part of the consideration for the Company’s 2009 acquisition of Ashburn Center, the Company is obligated to record contingent consideration arising from a fee agreement entered into with the seller in which the Company will be obligated to pay additional consideration if certain returns are achieved over the five year term of the agreement or if the property is sold within the term of the five year agreement. The Company initially recorded $0.7 million at the time of acquisition in December 2009, which represented the fair value of the Company’s potential obligation at acquisition. During the first quarter of 2010, the Company was able to lease vacant space at Ashburn Center faster than it had anticipated and, therefore, recorded additional contingent consideration of $0.7 million that reflected an increase in the potential consideration that may be owed to the seller. There was no significant change in the fair value of the contingent consideration during the three and six months ended June 30, 2011.

Other Expenses (Income)

Interest expense is summarized as follows:

	Three Months Ended				Six Months Ended				Three Months					Six Months
	June 30,				June 30,						Percent					Percent
(amounts in thousands)	2011		2010		2011		2010		Increase		Change			Increase		Change

The Company seeks to employ cost-effective financing methods to fund its acquisitions, development and redevelopment projects and to refinance its existing debt to provide greater balance sheet flexibility or to take advantage of lower interest rates. The methods used to fund the Company’s activities impact the period-over-period comparisons of interest expense.

Interest expense increased $2.4 million and $2.2 million for the three and six months ended June 30, 2011, respectively, compared with the same periods in 2010. At June 30, 2011, the Company had $811.2 million of debt outstanding with a weighted average interest rate of 5.0% compared with $613.5 million of debt outstanding with a weighted average interest rate of 5.4% at June 30, 2010.

The increase in the Company’s interest expense is primarily attributable to an increase in mortgage interest expense, which increased $2.2 million and $2.7 million for the three and six months ended June 30, 2011, respectively, compared with the same periods in 2010, due to the assumption of additional mortgages associated with the Company’s 2011 and 2010 acquisitions. During the fourth quarter of 2010, the Company entered into a $50.0 million secured term loan, which contributed additional interest expense of $0.4 million and $1.0 million for the three and six months ended June 30, 2011, respectively. The Company has incurred additional deferred financing costs with the assumption and issuance of new debt and the refinancing of its unsecured credit facility, which increased interest expense $0.2 million and $0.5 million for the three and six months ended June 30, 2011, respectively, compared with the same periods in 2010.

For the three months ended June 30, 2011, the Company experienced an increase in interest expense associated with its unsecured revolving credit facility of $0.4 million, due to a higher outstanding balance on the facility, and a decrease in interest expense of $0.1 million for the six months ended June 30, 2011 as a higher outstanding balance on the facility was offset by a lower applicable interest rate. For the three and six months ended June 30, 2011, the average balance on the Company’s unsecured revolving credit facility was $151.1 million and $132.9 million, respectively, with a weighted average interest rate of 3.1% and 3.2%, respectively, compared with $84.5 million and $117.9 million with a weighted average interest rate of 3.6% and 3.8% for the three and six months ended June 30, 2010, respectively.

41

The increase in interest expense for the three and six months ended June 30, 2011 compared with 2010 was partially offset by a decrease of $0.2 million and $0.5 million, respectively, in interest expense associated with the Company’s Exchangeable Senior Notes as $20.1 million of the notes were repurchased in the second quarter of 2010. Also, the Company recorded an increase in capitalized interest of $0.2 million and $0.5 million for the three and six months ended June 30, 2011, respectively, compared with the same periods in 2010.

The Company uses derivative financial instruments to manage exposure to interest rate fluctuations on its variable rate debt. On January 18, 2011, the Company fixed LIBOR at 1.474% on $50.0 million of its variable rate debt though an interest rate swap agreement that matures on January 15, 2014. During the first six months of 2010, the Company had fixed LIBOR on $85.0 million of variable rate debt through two interest rate swap agreements, which both expired in August 2010. As a result, interest expense related to the interest rate swap agreements decreased $0.4 million and $0.9 million for the three and six months ended March 31, 2011, respectively, compared with the same periods in 2010.

The Company recorded interest income related to these loans of $1.4 million and $2.2 million for the three and six months ended June 30, 2011, respectively.

Net loss (income) attributable to noncontrolling interests reflects the ownership interests in the Company’s net income or loss attributable to parties other than the Company. The change in net loss (income) attributable to noncontrolling interests can be attributed to an increase in net income during the three months ended June 30, 2011 and an increase in net loss during the six months ended June 30, 2011 compared with the same periods in 2010.

43

The percentage of the Operating Partnership owned by noncontrolling interests increased to 4.5% as of June 30, 2011 compared with 1.9% as of June 30, 2010, primarily due to the issuance of 1,418,715 Operating Partnership units to partially fund the acquisition of 840 First Street, NE during the second quarter of 2011. During the fourth quarter of 2010, the Company acquired Redland Corporate Center through a joint venture, in which, it has a 97% economic interest. The Company consolidates the operating results of the property and recognizes its joint venture partner’s percentage of gains or losses from Redland Corporate Center in net loss (income) attributable to noncontrolling interests. For the quarter ended June 30, 2011, the joint venture partner’s share of the income in the operations of Redland Corporate Center was $2 thousand.

Same Property Net Operating Income

Same Property Net Operating Income (“Same Property NOI”), defined as operating revenues (rental, tenant reimbursements and other revenues) less operating expenses (property operating expenses, real estate taxes and insurance) from the properties whose period-over-period operations can be viewed on a comparative basis , is a primary performance measure the Company uses to assess the results of operations at its properties. Same Property NOI is a non-GAAP measure. As an indication of the Company’s operating performance, Same Property NOI should not be considered an alternative to net income calculated in accordance with GAAP. A reconciliation of the Company’s Same Property NOI to net income from its consolidated statements of operations is presented below. The Same Property NOI results exclude corporate-level expenses, as well as certain transactions, such as the collection of termination fees, as these items vary significantly period-over-period and thus impact trends and comparability. Also, the Company eliminates depreciation and amortization expense, which are property level expenses, in computing Same Property NOI because these are non-cash expenses that are based on historical cost accounting assumptions and management believes these expenses do not offer the investor significant insight into the operations of the property. This presentation allows management and investors to distinguish whether growth or declines in net operating income are a result of increases or decreases in property operations or the acquisition of additional properties. While this presentation provides useful information to management and investors, the results below should be read in conjunction with the results from the consolidated statements of operations to provide a complete depiction of total Company performance. The Company also presents Same Property NOI results for each of its reporting segments, with the exception of its Washington, D.C. reporting segment, which did not have any properties owned for the entirety of the periods presented.

Liquidity and Capital Resources

Overview

The Company seeks to maintain a flexible balance sheet, with an appropriate balance of cash, debt, equity and available funds under its unsecured revolving credit facility, to readily provide access to capital given the volatility of the market and to position itself to take advantage of potential growth opportunities. The Company expects to meet short-term liquidity requirements generally through working capital, net cash provided by operations, and, if necessary, borrowings on its unsecured revolving credit facility. The Company’s short-term obligations consist primarily of the lease for its corporate headquarters, normal recurring operating expenses, regular debt payments, recurring expenditures for corporate and administrative needs, non-recurring expenditures such as capital improvements, tenant improvements and redevelopments, leasing commissions and dividends to preferred and common shareholders.

48

Over the next twelve months, the Company believes that it will generate sufficient cash flow from operations and have access to the capital resources, through debt and equity markets, necessary to expand and develop its business, to fund its operating and administrative expenses, to continue to meet its debt service obligations and to pay distributions in accordance with REIT requirements. However, the Company’s cash flow from operations could be adversely affected due to uncertain economic factors and volatility in the financial and credit markets. In particular, the Company cannot assure that its tenants will not default on their leases or fail to make full rental payments if their businesses are challenged due to, among other things, the economic conditions (particularly if the tenants are unable to secure financing to operate their businesses). This may be particularly true for the Company’s tenants that are smaller companies. Further, approximately 15% of the Company’s annualized base rent is scheduled to expire during the next eighteen months and, if it is unable to renew these leases or re-let the space, its cash flow could be negatively impacted.

The Company also believes that it will have sufficient cash flow or access to capital to meet its obligations over the next five years. The Company intends to meet long-term funding requirements for property acquisitions, development, redevelopment and other non-recurring capital improvements through net cash provided from operations, long-term secured and unsecured indebtedness, including borrowings under its unsecured revolving credit facility, unsecured term loan, secured term loans and unsecured senior notes, proceeds from disposal of strategically identified assets (outright and through joint ventures) and the issuance of equity and debt securities.

For example:

• In January 2011, the Company raised net proceeds of approximately $111 million through the issuance of 4.6 million 7.75% Series A Preferred Shares. The Company used $105.0 million of the proceeds to pay down a portion of its unsecured revolving credit facility;

• On June 16, 2011, the Company amended and restated its unsecured revolving credit facility. Under the new agreement, the capacity on the Company’s unsecured revolving credit facility was expanded from $225 million to $255 million and the maturity date was extended to January 2014 with a one-year extension at the Company’s option, which it intends to exercise. The interest rate on the unsecured revolving credit facility decreased from a range of LIBOR plus 275 to 375 basis points to a range of LIBOR plus 200 to 300 basis points, depending on the Company’s overall leverage; and

• On July 18, 2011, the Company entered into a three-tranche $175.0 million unsecured term loan. The unsecured term loan’s three tranches have maturity dates staggered in one-year intervals. Tranche A has an outstanding balance of $60.0 million at an interest rate of LIBOR plus 215 basis points and matures on July 18, 2016. Tranche B has an outstanding balance of $60.0 million at an interest rate of LIBOR plus 225 basis points and matures on July 18, 2017. Tranche C has an outstanding balance of $55.0 million at an interest rate of LIBOR plus 230 basis points and matures on July 18, 2018. The Company used the funds to pay down $117.0 million of the outstanding balance on its unsecured revolving credit facility, to repay its $50.0 million senior secured term loan and for other general corporate purposes.

The Company’s ability to raise funds through sales of debt and equity securities and access other third party sources of capital in the future will be dependent on, among other things, general economic conditions, general market conditions for REITs, rental rates, occupancy levels, market perceptions and the trading price of the Company’s shares. The Company will continue to analyze which sources of capital are most advantageous to it at any particular point in time, but the capital markets may not be consistently available on terms the Company deems attractive, or at all.

Financial Covenants

The Company’s outstanding corporate debt agreements contain specific financial covenants that may impact future financing decisions made by the Company or may be impacted by a decline in operations. These covenants differ by debt instrument and relate to the Company’s allowable leverage, minimum tangible net worth, fixed debt coverage and other financial metrics. As of June 30, 2011, the Company was in compliance with all of the financial covenants of its outstanding debt instruments. Below is a summary of certain financial covenants associated with the Company’s outstanding debt at June 30, 2011 (dollars in thousands):

Unsecured Revolving Credit Facility and Secured Term Loans

Non-Financial Covenants in Mortgage Loan Documents

Certain of the Company’s subsidiaries are borrowers on mortgage loans, the terms of which prohibit certain direct or indirect transfers of ownership interests in the borrower subsidiary (a “Prohibited Transfer”). Under the terms of the mortgage loan documents, a lender could assert that a Prohibited Transfer includes the trading of the Company’s common shares on the NYSE, the issuance of common shares by the Company, or the issuance of units of limited partnership interest in the Operating Partnership. As of June 30, 2011, the Company believes that there were eight mortgage loans with such Prohibited Transfer provisions, representing an aggregate principal amount outstanding of approximately $77 million. Two of these mortgage loans were entered into prior to the Company’s initial public offering (“IPO”) in 2003 and six were assumed subsequent to its IPO. In July 2011, the Company repaid two mortgages totaling $19.7 million with Prohibited Transfer provisions that were both assumed subsequent to its IPO. In each instance, the Company received the consent of the mortgage lender to consummate its IPO (for the two pre-IPO loans) or to acquire the property or the ownership interests of the borrower (for the post-IPO loans), including the assumption by its subsidiary of the mortgage loan. Generally, the underlying mortgage documents, previously applicable to a privately held owner, were not changed at the time of the IPO or the later loan assumptions, although the Company believes that each of the lenders or servicers was aware that the borrower’s ultimate parent was or would become a publicly traded company. Subsequent to the IPO and the assumption of these additional mortgage loans, the Company has issued new common shares and shares of the Company have been transferred on the New York Stock Exchange. Similarly, the Operating Partnership has issued units of limited partnership interest. To date, no lender or servicer has asserted that a Prohibited Transfer has occurred as a result of any such transfer of shares or units of limited partnership interest. If a lender were to be successful in any such action, the Company could be required to immediately repay or refinance the amounts outstanding, or the lender may be able to foreclose on the property securing the loan or take other adverse actions. In addition, in certain cases a Prohibited Transfer could result in the loan becoming fully recourse to the Company or its Operating Partnership. In addition, if a violation of a Prohibited Transfer provision were to occur that would permit the Company’s mortgage lenders to accelerate the indebtedness owed to them, it could result in an event of default under the Company’s Senior Unsecured Series A and Series B Notes, its unsecured revolving credit facility, its unsecured term loan, its two Secured Term Loans and its Exchangeable Senior Notes.

Cash Flows

Due to the nature of the Company’s business, it relies on net cash provided by operations to fund its short-term liquidity needs. Net cash provided by operations is substantially dependent on the continued receipt of rental payments and other expenses reimbursed by the Company’s tenants. The ability of tenants to meet their obligations, including the payment of rent contractually owed to the Company, and the Company’s ability to lease space to new or replacement tenants on favorable terms, could affect the Company’s cash available for short-term liquidity needs. The Company intends to meet short and long term funding requirements for debt maturities, interest payments, dividend distributions and capital expenditures through cash flow provided by operations, long-term secured and unsecured indebtedness, including borrowings under its unsecured revolving credit facility, proceeds from asset disposals and the issuance of equity and debt securities.

The Company could also fund building acquisitions, development, redevelopment and other non-recurring capital improvements through additional borrowings, issuance of Operating Partnership units or sales of assets, outright or through joint ventures.

Consolidated cash flow information is summarized as follows:

	Six Months Ended
	June 30,
(amounts in thousands)	2011			2010			Change
Cash provided by operating activities	$	16,546		$	17,948		$	(1,402	)
Cash used in investing activities		(70,570	)		(79,198	)		8,628
Cash provided by financing activities		33,459			63,411			(29,952	)

Net cash provided by operating activities decreased $1.4 million for the six months ended June 30, 2011 compared with the same period in 2010 primarily due to a $5.8 million increase in the amount of cash the Company contributed to its escrow and reserve accounts. During the six months ended June 30, 2011, the Company assumed three mortgages in financing its property acquisitions and under the provisions of the mortgages the Company was required to contribute funds to various escrow and reserve accounts. The decrease in cash provided by operating activities during the six months ended June 30, 2011 compared with the same period in 2010 was also the result of an increase in the Company’s deferred costs. The decrease in cash provided by operating activities was partially offset by an increase in the Company’s accounts payable and other liabilities for the six months ended June 30, 2011 compared with the same period in 2010.

Net cash used in investing activities decreased $8.6 million for the six months ended June 30, 2011 compared with the same period in 2010. The decrease in cash used in investing activities is primarily due to a reduction in cash used for property acquisitions. During the first six months of 2011, the Company used $20.0 million of cash to acquire four properties and a land parcel compared with the use of $81.5 million of cash to acquire two office buildings during the first six months of 2010. The 2011 acquisitions were partially funded by the assumption of mortgage debt totaling $139.4 million and the issuance of Operating Partnership units valued at $21.7 million, while the 2010 acquisitions were funded with cash. Also, the Company received proceeds of $26.9 million from the sale of three properties during the six months ended June 30, 2011 compared with proceeds of $11.4 million received from the sale of two properties during the same period in 2010. The decrease in cash used in investing activities was partially offset by the Company providing a $30.0 million subordinated loan to the owners of an office building located in Washington, D.C. During the six months ended June 30, 2011, the Company used $25.4 million of cash on additions to rental property and construction in progress compared with $6.2 million used during the six months ended June 30, 2010. Also, as of June 30, 2011, the Company had paid $20.3 million in deposits on potential acquisitions compared with $2.1 million in deposits paid as of June 30, 2010. Of the $20.3 million in deposits, $11.3 million related to proceeds received on the sale of a property in the second quarter of 2011, which was part of a like-kind exchange for a property acquired in July 2011. As part of a property acquisition in 2011, the Company was required to escrow $2.2 million for future tenant improvements.

Net cash provided by financing activities decreased $30.0 million for the six months ended June 30, 2011 compared with the same period in 2010. The Company repaid outstanding debt on its unsecured revolving credit facility and mortgage loans totaling $130.8 million for the six months ended June 30, 2011 compared with repayments of $93.5 million during the same period in 2010. The Company borrowed $78.0 million on its unsecured revolving credit facility during the six months ended June 30, 2011 compared with borrowings of $46.0 million on its facility and the issuance of a $39.0 million mortgage loan during the same period in 2010. During the six months ended June 30, 2011, the Company issued 4.6 million of Series A Preferred Shares for net proceeds of $111.0 million compared with the issuance of 6.3 million common shares for net proceeds of $87.0 million during the six months ended June 30, 2010. The proceeds from both the preferred and common share issuances during the first six months of 2011 and 2010 were used to pay down a portion of the outstanding balance on the Company’s unsecured revolving credit facility. As a result of the Company’s equity issuances during 2011 and 2010, its cash paid for dividends increased $9.8 million for the six months ended June 30, 2011 compared with the same period in 2010. During the six months ended June 30, 2011, the Company received $1.0 million from a consolidated joint venture partner, which was applied toward a deposit on a potential acquisition.

Contractual Obligations

As of June 30, 2011, the Company had development and redevelopment contractual obligations of $3.0 million outstanding, primarily related to redevelopment activities at Three Flint Hill, which is undergoing a complete redevelopment, and capital improvement obligations of $4.1 million outstanding. Capital improvement obligations represent commitments for roof, asphalt, HVAC and common area replacements contractually obligated as of June 30, 2011. Also, as of June 30, 2011, the Company had $4.8 million of tenant improvement obligations, primarily related to a tenant at Indian Creek Court. The Company anticipates meeting its contractual obligations related to its construction activities with cash from its operating activities. In the event cash from the Company’s operating activities is not sufficient to meet its contractual obligations, the Company can access additional capital through its unsecured revolving credit facility. At June 30, 2011, the Company had $91.0 million available under its unsecured revolving credit facility.

In connection with the Company’s 2009 acquisition of Ashburn Center, the Company entered into a contingent consideration fee agreement with the seller under which the Company will be obligated to pay additional consideration upon the property achieving stabilization per specified terms of the agreement. During the first quarter of 2010, the Company leased the remaining vacant space at the property and recorded a contingent consideration charge of $0.7 million, which reflected an increase in the anticipated fee to the seller. As of June 30, 2011, the Company’s total contingent consideration obligation to the former owner of Ashburn Center was approximately $1.4 million.

On December 29, 2010, the Company entered into an unconsolidated joint venture with AEW Capital Management, L.P. and acquired Aviation Business Park, a three-building, single-story, office park totaling 121,000 square feet in Glen Burnie, Maryland. The property was acquired by the joint venture through a deed-in-lieu of foreclosure in return for additional consideration to the owner if certain future leasing hurdles are met. As of June 30, 2011, the Company’s total contingent consideration obligation to the former owner of Aviation Business Park was approximately $0.1 million, which is not reflected on the Company’s condensed consolidated financial statements.

On March 25, 2011, the Company acquired 840 First Street, NE, in Washington, D.C. for an aggregate purchase price of $90.0 million, with up to $10.0 million of additional consideration payable upon the lease renewal by the building’s sole tenant or the re-tenanting of the property. At acquisition, the Company was in negotiations with the existing tenant to renew its lease through August 2023. As a result, the Company recorded a contingent consideration obligation of $9.4 million at acquisition. In July 2011, the building’s sole tenant renewed its lease. Based on the probability of renewal and lease terms used in the original estimate of fair value, the value of contingent consideration remained unchanged

As of June 30, 2011, the Company had $5.1 million in deposits outstanding for potential acquisitions. The Company had no other material contractual obligations as of June 30, 2011.

Distributions

The Company is required to distribute to its shareholders at least 90% of its REIT taxable income in order to qualify as a REIT, including some types of taxable income it recognizes for tax purposes but with regard to which it does not receive corresponding cash. In addition, the Company must distribute to its shareholders 100% of its taxable income to eliminate its U.S. federal income tax liability. Funds used by the Company to pay dividends on its common shares are provided through distributions from the Operating Partnership. For every common share of the Company, the Operating Partnership has issued to the Company a corresponding common unit. The Company is the sole general partner of and, as of June 30, 2011, owned 95.5% interest in, the Operating Partnership’s units. The remaining interests in the Operating Partnership are limited partnership interests, some of which are owned by several of the Company’s executive officers and trustees who contributed properties and other assets to the Company upon its formation, and other unrelated parties. The Operating Partnership is required to make cash distributions to the Company in an amount sufficient to meet its distribution requirements. The cash distributions by the Operating Partnership reduce the amount of cash that is available for general corporate purposes, which includes repayment of debt, funding acquisitions or construction activities, and for other corporate operating activities. On a quarterly basis, the Company’s management team recommends a distribution amount that is approved by the Company’s Board of Trustees. The amount of future distributions will be based on taxable income, cash from operating activities and available cash and at the discretion of the Company’s Board of Trustees.

52

Dividends

On July 25, 2011, the Company declared a dividend of $0.20 per common share, equating to an annualized dividend of $0.80 per common share. The dividend is payable on August 12, 2011 to common shareholders of record as of August 5, 2011. The Company also declared a dividend of $0.484375 per share on its Series A Preferred Shares. The dividend is payable on August 15, 2011 to preferred shareholders of record as of August 5, 2011.

Funds From Operations

Funds from operations (“FFO”) is a non-GAAP measure used by many investors and analysts that follow the real estate industry. The Company considers FFO a useful measure of performance for an equity REIT because it facilitates an understanding of the operating performance of its properties without giving effect to real estate depreciation and amortization, which assume that the value of real estate assets diminishes predictably over time. Since real estate values have historically risen or fallen with market conditions, the Company believes that FFO provides a meaningful indication of its performance. Management also considers FFO an appropriate supplemental performance measure given its wide use by and relevance to investors and analysts. FFO, reflecting the assumption that real estate asset values rise or fall with market conditions, principally adjusts for the effects of GAAP depreciation and amortization of real estate assets, which assume that the value of real estate diminishes predictably over time.

As defined by the National Association of Real Estate Investment Trusts (“NAREIT”) in its March 1995 White Paper (as amended in November 1999 and April 2002), FFO represents net income (computed in accordance with GAAP), excluding gains (losses) on sales of real estate, plus real estate-related depreciation and amortization and after adjustments for unconsolidated partnerships and joint ventures. The Company computes FFO in accordance with NAREIT’s definition, which may differ from the methodology for calculating FFO, or similarly titled measures, used by other companies and this may not be comparable to those presentations. The Company’s methodology for computing FFO adds back noncontrolling interests in the income from its Operating Partnership in determining FFO. The Company believes this is appropriate as Operating Partnership units are presented on an as-converted, one-for-one basis for shares of stock in determining FFO per diluted share.

Further, FFO does not represent amounts available for management’s discretionary use because of needed capital replacement or expansion, debt service obligations or other commitments and uncertainties, nor is it indicative of funds available to fund the Company’s cash needs, including its ability to make distributions. The Company’s presentation of FFO should not be considered as an alternative to net income (computed in accordance with GAAP) as an indicator of the Company’s financial performance or to cash flow from operating activities (computed in accordance with GAAP) as an indicator of its liquidity.

The following table presents a reconciliation of net (loss) income available to common shareholders to FFO available to common shareholders and unitholders (amounts in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,

Off-Balance Sheet Arrangements

On January 1, 2010 and March 17, 2009, the Company deconsolidated the joint ventures that own RiversPark I and II, respectively, and removed all their related assets and liabilities from its consolidated balance sheets as of the date of deconsolidation. The Company remains liable for $7.0 million of mortgage debt, which represents its proportionate share. During the fourth quarter 2010, the Company entered into separate unconsolidated joint ventures with a third party to acquire 1750 H Street, NW and Aviation Business Park. For more information, see footnote 5 - Investment in Affiliates.

Forward Looking Statements

This report contains forward-looking statements within the meaning of the federal securities laws. Forward-looking statements, which are based on certain assumptions and describe future plans, strategies and expectations of the Company, are generally identifiable by use of the words “believe,” “expect,” “intend,” “anticipate,” “estimate,” “project” or similar expressions. The Company’s ability to predict results or the actual effect of future plans or strategies is inherently uncertain. Certain factors that could cause actual results to differ materially from the Company’s expectations include changes in general or regional economic conditions; the Company’s ability to timely lease or re-lease space at current or anticipated rents; changes in interest rates; changes in operating costs; the Company’s ability to complete current and future acquisitions; the Company’s ability to obtain additional financing; the Company’s ability to manage its current debt levels and repay or refinance its indebtedness upon maturity or other required payment dates; the Company’s ability to obtain debt and/or financing on attractive terms, or at all; and other risks detailed under “Risk Factors” in Part I, Item 1A in our Annual Report on Form 10-K for the year ended December 31, 2010 and in the other documents the Company files with the SEC. Many of these factors are beyond the Company’s ability to control or predict. Forward-looking statements are not guarantees of performance. For forward-looking statements herein, the Company claims the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. The Company assumes no obligation to update or supplement forward-looking statements that become untrue because of subsequent events. We have no duty to, and do not intend to, update or revise the forward-looking statements in this discussion after the date hereof, except as may be required by law. In light of these risks and uncertainties, you should keep in mind that any forward-looking statement made in this discussion, or elsewhere, might not occur.

ITEM 3: QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

The Company’s future income, cash flows and fair values relevant to financial instruments are dependent upon prevailing market interest rates. In the normal course of business, the Company is exposed to the effect of interest rate changes. The Company has historically entered into derivative agreements to mitigate exposure to unexpected changes in interest. Market risk refers to the risk of loss from adverse changes in market interest rates. The Company periodically uses derivative financial instruments to seek to manage, or hedge, interest rate risks related to its borrowings. The Company does not use derivatives for trading or speculative purposes and only enters into contracts with major financial institutions based on their credit rating and other factors. The Company intends to enter into derivative agreements only with counterparties that it believes have a strong credit rating to mitigate the risk of counterparty default or insolvency.

At June 30, 2011, the Company’s exposure to variable interest rates consisted of $164.0 million of borrowings on its unsecured revolving credit facility and $100.0 million on three secured term loans. A change in interest rates of 1% would result in an increase or decrease of $2.6 million in interest expense on an annualized basis. As of June 30, 2011, the Company has hedged $50.0 million of its variable rate debt through an interest rate swap agreement that matures on January 15, 2014. During July 2011, the Company entered into four interest rate swap agreements that fixed LIBOR on $120 million of its variable rate debt. The table below summarizes the Company’s four new interest rate swap agreements, which were all effective on July 18, 2011 (dollars in thousands):

			Interest Rate	Fixed LIBOR
Maturity Date	Amount		Contractual Component	Interest Rate
July 2016	$	35,000	LIBOR		1.754	%
July 2016		25,000	LIBOR		1.7625	%
July 2017		30,000	LIBOR		2.093	%
July 2017		30,000	LIBOR		2.093	%

54

For fixed rate debt, changes in interest rates generally affect the fair value of debt but not the earnings or cash flow of the Company. See footnote 10, Fair Value Measurements for more information on the fair value of the Company’s debt.

ITEM 4: CONTROLS AND PROCEDURES

The Company carried out an evaluation with the participation of the Company’s management, including its Chief Executive Officer and Chief Financial Officer, of the effectiveness of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures are effective to ensure that information required to be disclosed by the Company in the reports that the Company files, or submits under the Exchange Act, is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

There has been no change in the Company’s internal control over financial reporting during the quarter ended June 30, 2011, that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II: OTHER INFORMATION

Item 1. Legal Proceedings

As of June 30, 2011, the Company was not subject to any material pending legal proceedings.

Item 1A. Risk Factors

In addition to the risk factors previously disclosed in Item 1A, “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010, the Company is subject to the following additional risk:

The recent downgrade of the U.S. Government’s credit rating could cause a worsening of general economic conditions and an increase in interest rates, which could materially adversely affect our business, financial condition, results of operations and ability to make distributions to our shareholders.

On August 2, 2011, legislation was enacted to increase the federal debt ceiling and to reduce future U.S. Government spending levels by as much as $2.4 trillion over the next decade. Notwithstanding the passage of this legislation, there remains uncertainty about whether and when the U.S. Government will implement the budget cuts, which has resulted in continued concerns that the U.S. Government could default on its obligations in the future. On August 5, 2011, Standard & Poor’s downgraded the U.S. Government’s credit rating for the first time in history due to its belief that the legislation was inadequate to address the country’s growing debt burden. The decision of Standard & Poor’s to downgrade the U.S. Government’s credit rating could create broader financial and global banking turmoil and uncertainty and could lead to a significant rise in interest rates. These events could cause the interest rates on our borrowings and our cost of capital to increase significantly, and could extend to our tenants. As a result, these events could materially and adversely affect our interest expense and other costs of borrowing and make it more difficult to refinance our indebtedness when it becomes due and payable, lease vacant space and re-let space as leases expire and to acquire properties on attractive terms, and could adversely affect the ability of our tenants to meet their lease obligations or alter their intent, need or ability to renew expiring leases. Furthermore, the downgrade of the U.S. Government’s credit rating could result in significant volatility in global stock markets, which could cause the market price of our common and preferred stock to decrease significantly. Any of these outcomes could have a material adverse effect on our business, financial condition, liquidity, results of operations and ability to make distributions to our shareholders.

Re: Amendment No. 2 to Second Amended and Restated Revolving Credit Agreement

Ladies and Gentlemen:

We refer to the Second Amended and Restated Revolving Credit Agreement dated as of December 29, 2009 (as amended by Amendment No. 1 dated May 14, 2010 and as further modified by the Commitment Increase Agreement, dated June 1, 2010, and as in effect from time to time, the “Credit Agreement”), by and among FIRST POTOMAC REALTY INVESTMENT LIMITED PARTNERSHIP, a Delaware limited partnership, and certain of its Wholly-owned Subsidiaries (collectively, the “Borrowers”), KEYBANK NATIONAL ASSOCIATION and the other lending institutions which are parties thereto (individually, a “Lender” and collectively, the “Lenders”), KEYBANK NATIONAL ASSOCIATION, as administrative agent for itself and each other Lender (the “Agent”) and certain other parties. Capitalized terms used in this letter of agreement (this “Amendment”) which are not defined herein, but which are defined in the Credit Agreement, shall have the same meanings herein as therein, as the context so requires.

We have requested the Lenders (i) to make certain amendments to the Credit Agreement, including that the covenant relating to Restrictions on Indebtedness be amended to permit the Borrowers to incur unsecured Indebtedness subject to certain conditions and (ii) to provide certain consents under the Credit Agreement, including that the Borrowers be permitted to make a minority investment, as more fully described in Annex 1 (the “950 F Street Investment”), and you have advised us that the Lenders are prepared and would be pleased to make the amendments and provide the consents so requested by us on the condition that we join in this Amendment.

Accordingly, in consideration of these premises, the promises, mutual covenants and agreements contained in this Amendment, and fully intending to be legally bound by this Amendment, we hereby agree as follows:

ARTICLE I

AMENDMENTS TO CREDIT AGREEMENT

Effective as of October 27, 2010 (the “Amendment Date”), and subject to the fulfillment of the conditions contained in Article III of this Amendment, the Credit Agreement is amended in each of the following respects:

(a) The term “Loan Documents” shall, wherever used in the Credit Agreement or any of the other Loan Documents, be deemed to also mean and include this Amendment.

(b) Clause (iii) of the proviso contained in Section 9.1(f) of the Credit Agreement is amended to read in its entirety as follows:

“(iii) such Indebtedness, in the aggregate, does not exceed forty percent (40%) of Consolidated Gross Asset Value (it being acknowledged, for the avoidance of doubt, that the outstanding Indebtedness under the 2007 Term Loan and the 2008 Term Loan shall count against the fifteen percent (15%) basket referred to in clause (i) above)”

(c) Section 9.1 of the Credit Agreement is further amended (x) by inserting a new clause (i) immediately following clause (h) thereof (and by deleting the word “and” at the end of clause (g) and inserting “; and” at the end of clause (h) in place of the period) and (y) by inserting the following sentence after such new clause (i):

“(i) unsecured Indebtedness of the Borrower (including subsidiary guarantees by any Subsidiary of FPLP) and unsecured guarantees by the Trust with respect to such unsecured Indebtedness, provided that (i) such Indebtedness shall at all times remain unsecured in all respects (including, for the avoidance of doubt, that the Equity Interests of FPLP or any other Borrower shall not be pledged as security for any such Indebtedness), (ii) both before and immediately after giving effect to any such unsecured Indebtedness, no Default or Event of Default has occurred or is continuing, (iii) prior to incurring any such unsecured Indebtedness, the Borrower has provided the Agent with a certificate in the form of Exhibit C-2 evidencing compliance with each of the financial covenants set forth in §10 of the Credit Agreement on a pro forma basis immediately after giving effect to such unsecured Indebtedness, and (iv) such unsecured Indebtedness shall not be in the nature of a revolving credit facility.

For the avoidance of doubt, the 2007 Term Loan and the 2008 Term Loan are also permitted Indebtedness under this §9.1.”

2

(d) Section 9.2(ix) of the Credit Agreement is amended by inserting the following new parenthetical at the end thereof (before the period): “(other than the unsecured Indebtedness permitted under clause (i) of §9.1)”.

ARTICLE II

CONSENT TO 950 F STREET INVESTMENT

As more particularly described in Annex 1 attached hereto, FPLP, through a Subsidiary, intends to aquire a preferred equity interest in Jemal LLC (as defined in Annex 1). Jemal LLC is the sole managing member of a special purpose limited liability company (“SPE”) that owns the office building located at 950 F Street, NW, Washington, DC (the “F Street Office Building”). The 950 F Street Investment will be made substantially on the terms outlined by the Borrowers in Annex 1. In addition, the 950 F Street Investment will, in accordance with GAAP, be treated as Indebtedness by the Borrowers, and accordingly, the Borrowers have requested that for purposes of the Credit Agreement, including the financial covenants and related definitions contained therein, the 950 F Street Investment be treated as an acquisition of Indebtedness and accounted for at its cost basis (similar to the treatment of an acquisition of a Mortgage Note) and not be treated as an Investment in a Partially-Owned Entity (the “Cost Basis Treatment”).

The Borrowers have requested that the Lenders consent to (i) the 950 F Street Investment for purposes of the Credit Agreement, including Section 9.3 thereof, (ii) the Cost Basis Treatment for the 950 F Street Investment and (iii) the use of proceeds of the Loans in order to make the 950 F Street Investment.

The Lenders hereby consent to (x) the 950 F Street Investment, (y) the Cost Basis Treatment for the 950 F Street Investment and (z) the use of proceeds of the Loans to make the 950 F Street Investment, subject in each case to the following conditions: (i) at the time of the 950 F Street Investment and after giving effect thereto (and after giving effect to this consent), no Default or Event of Default shall have occurred or be continuing, (ii) the F Street Office Building shall at all times be a Permitted Property, (iii) the 950 F Street Investment be made on terms substantially consistent with the terms outlined in Annex 1, (iv) the Cost Basis Treatment for the 950 F Street Investment is permitted under GAAP, (v) after giving effect to the Cost Basis Treatment for the 950 F Street Investment, the Borrowers are in compliance with Section 9.3(h) of the Credit Agreement (it being agreed that, for so long as it remains outstanding, the 950 F Street Investment shall be deemed to be a “Mortgage Note” for purposes of determining compliance with Section 9.3(h) of the Credit Agreement), (vi) any Indebtedness to which the F Street Office Building, the SPE or Jemal LLC is subject is and remains Without Recourse to FPLP or any of its Subsidiaries and neither FPLP nor any of its Subsidiaries pledges any of its respective assets or properties in support of any such Indebtedness, and (vii) FPLP delivering to the Agent, at its request, copies of each of the agreements and documents evidencing the 950 F Street Investment and the transactions relating thereto (including, without limitation, operating agreements and loan documents of the SPE).

Nothing in this Amendment shall be construed to imply any willingness on the part of the Agent or the Lenders to grant any similar or future consent or waiver of any of the terms and conditions of the Credit Agreement or the other Loan Documents.

ANNEX 1

FPLP, through a subsidiary, is proposing to make a preferred equity investment in a single purpose entity limited liability company owned by Douglas Jemal (the “Jemal LLC”) and certain of his relatives and affiliates. The Jemal LLC is the sole and managing member of an single purpose entity limited liability company (the “Property Owner LLC”) that owns an office building located at 950 F Street, NW, Washington, DC. The amount of the proposed investment is twenty-five million dollars ($25,000,000), and FPLP will be entitled to a preferred return of 12.5% per annum (17.5% in the event of a default or after seven years). The Jemal LLC must also maintain a cash reserve account in an amount equal to 6 monthly payments of the preferred return. The preferred interest is redeemable by the Jemal LLC at any time after the third anniversary of issuance. Prior to that time, the preferred interest may only be redeemed upon a sale of the property with the consent of FPLP and with the payment of a make-whole premium. The preferred interest will become redeemable at the option of FPLP beginning in 2018. In the event that the Property Owner LLC defaults in the payment of any preferred return or if the Property Owner LLC defaults on its mortgage loan in the original principal amount of One Hundred Fifty Million Dollars ($150,000,000), FPLP will have the right to cause the Jemal LLC to redeem the common equity at 80% of fair market value, at which time FPLP will become the sole member of the Jemal LLC. FPLP as preferred member also will have customary major decision veto rights.

Re: Amendment No. 3 to Secured Term Loan Agreement

Ladies and Gentlemen:

We refer to the Secured Term Loan Agreement dated as of August 11, 2008 (as amended and in effect from time to time, the “Credit Agreement”), by and among FIRST POTOMAC REALTY INVESTMENT LIMITED PARTNERSHIP, a Delaware limited partnership (the “Borrower”), KEYBANK NATIONAL ASSOCIATION and the other lending institutions which are parties thereto (individually, a “Lender” and collectively, the “Lenders”), and KEYBANK NATIONAL ASSOCIATION, as administrative agent for itself and each other Lender (the “Agent”). Capitalized terms used in this letter of agreement (this “Amendment”) which are not defined herein, but which are defined in the Credit Agreement, shall have the same meanings herein as therein, as the context so requires.

We have requested the Lenders (i) to make certain amendments to the Credit Agreement, including that the covenant relating to Restrictions on Indebtedness be amended to permit the Borrower to incur unsecured Indebtedness subject to certain conditions and (ii) to provide certain consents under the Credit Agreement, including that the Borrower be permitted to make a minority investment, as more fully described in Annex 1 (the “950 F Street Investment”), and you have advised us that the Lenders are prepared and would be pleased to make the amendments and provide the consents so requested by us on the condition that we join in this Amendment.

Accordingly, in consideration of these premises, the promises, mutual covenants and agreements contained in this Amendment, and fully intending to be legally bound by this Amendment, we hereby agree as follows:

ARTICLE I

AMENDMENTS TO CREDIT AGREEMENT

Effective as of October 27, 2010 (the “Amendment Date”), and subject to the fulfillment of the conditions contained in Article III of this Amendment, the Credit Agreement is amended in each of the following respects:

(a) The term “Loan Documents” shall, wherever used in the Credit Agreement or any of the other Loan Documents, be deemed to also mean and include this Amendment.

(b) Clause (iii) of the proviso contained in Section 9.1(f) of the Credit Agreement is amended to read in its entirety as follows and to add the parenthetical at the end thereof:

“(iii) such Indebtedness, in the aggregate, does not exceed forty percent (40%) of Consolidated Gross Asset Value (it being acknowledged, for the avoidance of doubt, that the outstanding Indebtedness hereunder and under the Existing Term Loan Agreement shall count against the fifteen percent (15%) basket referred to in clause (i) above)”.

(c) Section 9.1 of the Credit Agreement is further amended (x) by inserting a new clause (i) immediately following clause (h) thereof (and by deleting the word “and” at the end of clause (g) and inserting “; and” at the end of clause (h) in place of the period) and (y) by inserting the following sentence after such new clause (i):

“(i) unsecured Indebtedness of the Borrower (including subsidiary guarantees by any Subsidiary of FPLP) and unsecured guarantees by the Trust with respect to such unsecured Indebtedness, provided that (i) such Indebtedness shall at all times remain unsecured in all respects (including, for the avoidance of doubt, that the Equity Interests of the Borrower or any Subsidiary Guarantor shall not be pledged as security for any such Indebtedness), (ii) both before and immediately after giving effect to any such unsecured Indebtedness, no Default or Event of Default has occurred or is continuing, (iii) prior to incurring any such unsecured Indebtedness, the Borrower has provided the Agent with a certificate in the form of Exhibit C-2 evidencing compliance with each of the financial covenants set forth in §10 of the Credit Agreement on a pro forma basis immediately after giving effect to such unsecured Indebtedness, and (iv) such unsecured Indebtedness shall not be in the nature of a revolving credit facility.

ARTICLE II

CONSENT TO 950 F STREET INVESTMENT

As more particularly described in Annex 1 attached hereto, FPLP, through a Subsidiary, intends to aquire a preferred equity interest in Jemal LLC (as defined in Annex 1). Jemal LLC is the sole managing member of a special purpose limited liability company (“SPE”) that owns the office building located at 950 F Street, NW, Washington, DC (the “F Street Office Building”). The 950 F Street Investment will be made substantially on the terms outlined by the Borrower in Annex 1. In addition, the 950 F Street Investment will, in accordance with GAAP, be treated as Indebtedness by the Borrower, and accordingly, the Borrower has requested that for purposes of the Credit Agreement, including the financial covenants and related definitions contained therein, the 950 F Street Investment be treated as an acquisition of Indebtedness and accounted for at its cost basis (similar to the treatment of an acquisition of a Mortgage Note) and not be treated as an Investment in a Partially-Owned Entity (the “Cost Basis Treatment”).

The Borrower has requested that the Lenders consent to (i) the 950 F Street Investment for purposes of the Credit Agreement, including Section 9.3 thereof and (ii) the Cost Basis Treatment for the 950 F Street.

The Lenders hereby consent to (x) the 950 F Street Investment and (y) the Cost Basis Treatment for the 950 F Street Investment, subject in each case to the following conditions: (i) at the time of the 950 F Street Investment and after giving effect thereto (and after giving effect to this consent), no Default or Event of Default shall have occurred or be continuing, (ii) the F Street Office Building shall at all times be a Permitted Property, (iii) the 950 F Street Investment be made on terms substantially consistent with the terms outlined in Annex 1, (iv) the Cost Basis Treatment for the 950 F Street Investment is permitted under GAAP, (v) after giving effect to the Cost Basis Treatment for the 950 F Street Investment, the Borrowers are in compliance with Section 9.3(h) of the Credit Agreement (it being agreed that, for so long as it remains outstanding, the 950 F Street Investment shall be deemed to be a “Mortgage Note” for purposes of determining compliance with Section 9.3(h) of the Credit Agreement), (vi) any Indebtedness to which the F Street Office Building, the SPE or Jemal LLC is subject is and remains Without Recourse to FPLP or any of its Subsidiaries and neither FPLP nor any of its Subsidiaries pledges any of its respective assets or properties in support of any such Indebtedness, and (vii) FPLP delivering to the Agent, at its request, copies of each of the agreements and documents evidencing the 950 F Street Investment and the transactions relating thereto (including, without limitation, operating agreements and loan documents of the SPE).

4

(d) No Implied Waiver. Except as expressly set forth in this Amendment, this Amendment shall not, by implication or otherwise, limit, impair, constitute a waiver of or otherwise affect any rights or remedies of the Agent or the Lenders under the Credit Agreement or the other Loan Documents, nor alter, modify, amend or in any way affect any of the terms, obligations or covenants contained in the Credit Agreement or the Loan Documents, all of which shall continue in full force and effect. Nothing in this Amendment shall be construed to imply any willingness on the part of the Agent or the Lenders to grant any similar or future consent or waiver of any of the terms and conditions of the Credit Agreement or the other Loan Documents.

ARTICLE V

MISCELLANEOUS

ANNEX 1

FPLP, through a subsidiary, is proposing to make a preferred equity investment in a single purpose entity limited liability company owned by Douglas Jemal (the “Jemal LLC”) and certain of his relatives and affiliates. The Jemal LLC is the sole and managing member of an single purpose entity limited liability company (the “Property Owner LLC”) that owns an office building located at 950 F Street, NW, Washington, DC. The amount of the proposed investment is twenty-five million dollars ($25,000,000), and FPLP will be entitled to a preferred return of 12.5% per annum (17.5% in the event of a default or after seven years). The Jemal LLC must also maintain a cash reserve account in an amount equal to 6 monthly payments of the preferred return. The preferred interest is redeemable by the Jemal LLC at any time after the third anniversary of issuance. Prior to that time, the preferred interest may only be redeemed upon a sale of the property with the consent of FPLP and with the payment of a make-whole premium. The preferred interest will become redeemable at the option of FPLP beginning in 2018. In the event that the Property Owner LLC defaults in the payment of any preferred return or if the Property Owner LLC defaults on its mortgage loan in the original principal amount of One Hundred Fifty Million Dollars ($150,000,000), FPLP will have the right to cause the Jemal LLC to redeem the common equity at 80% of fair market value, at which time FPLP will become the sole member of the Jemal LLC. FPLP as preferred member also will have customary major decision veto rights.

Re: Amendment No. 4 to Secured Term Loan Agreement

Ladies and Gentlemen:

We refer to the Secured Term Loan Agreement dated as of August 7, 2007 (as amended and in effect from time to time, the “Credit Agreement”), by and among FIRST POTOMAC REALTY INVESTMENT LIMITED PARTNERSHIP, a Delaware limited partnership (the “Borrower”), KEYBANK NATIONAL ASSOCIATION and the other lending institutions which are parties thereto (individually, a “Lender” and collectively, the “Lenders”), and KEYBANK NATIONAL ASSOCIATION, as administrative agent for itself and each other Lender (the “Agent”). Capitalized terms used in this letter of agreement (this “Amendment”) which are not defined herein, but which are defined in the Credit Agreement, shall have the same meanings herein as therein, as the context so requires.

We have requested the Lenders (i) to make certain amendments to the Credit Agreement, including that the covenant relating to Restrictions on Indebtedness be amended to permit the Borrower to incur unsecured Indebtedness subject to certain conditions and (ii) to provide certain consents under the Credit Agreement, including that the Borrower be permitted to make a minority investment, as more fully described in Annex 1 (the “950 F Street Investment”), and you have advised us that the Lenders are prepared and would be pleased to make the amendments and provide the consents so requested by us on the condition that we join in this Amendment.

Accordingly, in consideration of these premises, the promises, mutual covenants and agreements contained in this Amendment, and fully intending to be legally bound by this Amendment, we hereby agree as follows:

ARTICLE I

AMENDMENTS TO CREDIT AGREEMENT

Effective as of October 27, 2010 (the “Amendment Date”), and subject to the fulfillment of the conditions contained in Article III of this Amendment, the Credit Agreement is amended in each of the following respects:

(a) The term “Loan Documents” shall, wherever used in the Credit Agreement or any of the other Loan Documents, be deemed to also mean and include this Amendment.

(b) Clause (iii) of the proviso contained in Section 9.1(f) of the Credit Agreement is amended to read in its entirety as follows:

“(iii) such Indebtedness, in the aggregate, does not exceed forty percent (40%) of Consolidated Gross Asset Value (it being acknowledged, for the avoidance of doubt, that the outstanding Indebtedness hereunder and under the 2008 Term Loan shall count against the fifteen percent (15%) basket referred to in clause (i) above)”.

(c) Section 9.1 of the Credit Agreement is further amended (x) by inserting a new clause (i) immediately following clause (h) thereof (and by deleting the word “and” at the end of clause (g) and inserting “; and” at the end of clause (h) in place of the period) and (y) by inserting the following sentence after such new clause (i):

“(i) unsecured Indebtedness of the Borrower (including subsidiary guarantees by any Subsidiary of FPLP) and unsecured guarantees by the Trust with respect to such unsecured Indebtedness, provided that (i) such Indebtedness shall at all times remain unsecured in all respects (including, for the avoidance of doubt, that the Equity Interests of the Borrower or any Subsidiary Guarantor shall not be pledged as security for any such Indebtedness), (ii) both before and immediately after giving effect to any such unsecured Indebtedness, no Default or Event of Default has occurred or is continuing, (iii) prior to incurring any such unsecured Indebtedness, the Borrower has provided the Agent with a certificate in the form of Exhibit C-2 evidencing compliance with each of the financial covenants set forth in §10 of the Credit Agreement on a pro forma basis immediately after giving effect to such unsecured Indebtedness, and (iv) such unsecured Indebtedness shall not be in the nature of a revolving credit facility.

For the avoidance of doubt, the Indebtedness under the Unsecured Revolver Agreement and the 2008 Term Loan (as defined in the Unsecured Revolver Agreement) are also permitted Indebtedness under this §9.1.”

2

ARTICLE II

CONSENT TO 950 F STREET INVESTMENT

As more particularly described in Annex 1 attached hereto, FPLP, through a Subsidiary, intends to aquire a preferred equity interest in Jemal LLC (as defined in Annex 1). Jemal LLC is the sole managing member of a special purpose limited liability company (“SPE”) that owns the office building located at 950 F Street, NW, Washington, DC (the “F Street Office Building”). The 950 F Street Investment will be made substantially on the terms outlined by the Borrower in Annex 1. In addition, the 950 F Street Investment will, in accordance with GAAP, be treated as Indebtedness by the Borrower, and accordingly, the Borrower has requested that for purposes of the Credit Agreement, including the financial covenants and related definitions contained therein, the 950 F Street Investment be treated as an acquisition of Indebtedness and accounted for at its cost basis (similar to the treatment of an acquisition of a Mortgage Note) and not be treated as an Investment in a Partially-Owned Entity (the “Cost Basis Treatment”).

The Borrower has requested that the Lenders consent to (i) the 950 F Street Investment for purposes of the Credit Agreement, including Section 9.3 thereof and (ii) the Cost Basis Treatment for the 950 F Street Investment.

The Lenders hereby consent to (x) the 950 F Street Investment and (y) the Cost Basis Treatment for the 950 F Street Investment, subject in each case to the following conditions: (i) at the time of the 950 F Street Investment and after giving effect thereto (and after giving effect to this consent), no Default or Event of Default shall have occurred or be continuing, (ii) the F Street Office Building shall at all times be a Permitted Property, (iii) the 950 F Street Investment be made on terms substantially consistent with the terms outlined in Annex 1, (iv) the Cost Basis Treatment for the 950 F Street Investment is permitted under GAAP, (v) after giving effect to the Cost Basis Treatment for the 950 F Street Investment, the Borrowers are in compliance with Section 9.3(h) of the Credit Agreement (it being agreed that, for so long as it remains outstanding, the 950 F Street Investment shall be deemed to be a “Mortgage Note” for purposes of determining compliance with Section 9.3(h) of the Credit Agreement), (vi) any Indebtedness to which the F Street Office Building, the SPE or Jemal LLC is subject is and remains Without Recourse to FPLP or any of its Subsidiaries and neither FPLP nor any of its Subsidiaries pledges any of its respective assets or properties in support of any such Indebtedness, and (vii) FPLP delivering to the Agent, at its request, copies of each of the agreements and documents evidencing the 950 F Street Investment and the transactions relating thereto (including, without limitation, operating agreements and loan documents of the SPE).

ANNEX 1

FPLP, through a subsidiary, is proposing to make a preferred equity investment in a single purpose entity limited liability company owned by Douglas Jemal (the “Jemal LLC”) and certain of his relatives and affiliates. The Jemal LLC is the sole and managing member of an single purpose entity limited liability company (the “Property Owner LLC”) that owns an office building located at 950 F Street, NW, Washington, DC. The amount of the proposed investment is twenty-five million dollars ($25,000,000), and FPLP will be entitled to a preferred return of 12.5% per annum (17.5% in the event of a default or after seven years). The Jemal LLC must also maintain a cash reserve account in an amount equal to 6 monthly payments of the preferred return. The preferred interest is redeemable by the Jemal LLC at any time after the third anniversary of issuance. Prior to that time, the preferred interest may only be redeemed upon a sale of the property with the consent of FPLP and with the payment of a make-whole premium.

§2. THE TERM LOAN.

§2.1 Commitment to Lend. Subject to the provisions of §2.4, §12 and the other terms and conditions set forth in this Agreement, each of the Lenders severally agrees to make a term loan to the Borrower on the Closing Date in an aggregate principal amount equal to such Lender’s Commitment Percentage of the Total Commitment. The outstanding amount of the Term Loan shall not at any time exceed the Total Commitment. In no event shall any Lender be required to fund any amounts in excess of its then-current Commitment.

-23-

The Term Loan shall be made pro rata in accordance with each Lender’s Commitment Percentage. The request for the Term Loan shall constitute a representation and warranty by the Borrower that the conditions set forth in §12 have been satisfied as of the Closing Date, provided that the making of such representation and warranty by the Borrower shall not limit the right of any Lender not to lend if such conditions have not been met. No portion of the Term Loan or other extension of credit shall be required to be made by any Lender unless all of the conditions contained in §12 have been satisfied as of the Closing Date.

§2.2. The Notes. The Term Loan shall be evidenced by the Notes. A Note shall be payable to the order of each Lender in an aggregate principal amount equal to such Lender’s Commitment. The Borrower irrevocably authorizes each Lender to make or cause to be made an appropriate notation on such Lender’s applicable Note Record reflecting the making of its portion of the Term Loan or (as the case may be) the receipt of any payment thereon. The outstanding amount of the Term Loan set forth on such applicable Note Record shall be prima facie evidence of the principal amount thereof owing and unpaid to such Lender, but the failure to record, or any error in so recording, any such amount on such Note Record shall not limit or otherwise affect the rights and obligations of the Borrower hereunder or under any Note to make payments of principal of or interest on any Note when due.

§2.3. Interest on the Term Loan; Fees.

(a) Each Base Rate Loan shall bear interest for the period commencing with the Drawdown Date thereof and ending on the last day of each Interest Period with respect thereto (unless earlier paid in accordance with §3.2) at a rate equal to the Base Rate plus the Applicable Base Rate Margin.

(b) Each Libor Rate Loan shall bear interest for the period commencing with the Drawdown Date thereof and ending on the last day of each Interest Period with respect thereto (unless earlier paid in accordance with §3.2) at a rate equal to the Libor Rate determined for such Interest Period plus the Applicable Libor Margin.

(c) With reference to Base Rate Loans, the “Applicable Base Rate Margin” shall be equal to 2.25% and, with reference to Libor Rate Loans, the “Applicable Libor Margin” shall be equal to 3.50%.

(d) The Borrower unconditionally promises to pay interest on the Term Loan in arrears on each Interest Payment Date with respect thereto, and when the principal of such Term Loan is due (whether at maturity, by reason of acceleration or otherwise).

-24-

§2.4. Request for the Term Loan.

The following provisions shall apply to the initial request by the Borrower for the Term Loan:

(i) The Borrower shall submit a Completed Loan Request to the Agent. The Completed Loan Request shall be irrevocable and binding on the Borrower and shall obligate the Borrower to accept the Term Loan requested from the Lenders on the Closing Date.

(ii) The Completed Loan Request shall specify: (1) the principal amount of the Term Loan, (2) the Interest Period applicable to such Term Loan (or portions thereof), and (3) the Type of Loan being requested, and certifying that, after giving effect to such requested Term Loan, no Default or Event of Default will exist under this Agreement or any other Loan Document and that, after giving effect to the Term Loan, the Borrower is in compliance with the covenants set forth in §10 (which calculations required by such covenants shall be submitted with such Completed Loan Request).

(iii) No Lender shall be obligated to fund any portion of the Term Loan unless:

(a) a Completed Loan Request has been timely received by the Agent as provided in subsection (i) above; and

(b) both before and after giving effect to the Term Loan to be made pursuant to the Completed Loan Request, all of the conditions contained in §12 shall have been satisfied as of the Closing Date.

§2.5. Conversion Options.

(a) The Borrower may elect from time to time to convert any portion of the outstanding Term Loan to another Type, provided that (i) subject to the further proviso at the end of this §2.5(a) and subject to §2.5(b) and §2.5(d), with respect to any conversion of a Base Rate Loan to a Libor Rate Loan (or a continuation of a Libor Rate Loan, as provided in §2.5(b)), the Borrower shall give the Agent at least three (3) Business Days’ prior written notice of such election, which such notice must be received by the Agent by 10:00 a.m. on any Business Day; and (ii) no Loan may be converted into a Libor Rate Loan when any Default or Event of Default has occurred and is continuing. All or any part of the outstanding Term Loan of any Type may be converted as provided herein, provided that each Conversion Request relating to the conversion of a Base Rate Loan to a Libor Rate Loan shall be for an amount equal to $1,000,000 or an integral multiple of $100,000 in excess thereof and shall be irrevocable by the Borrower.

-25-

(b) Any portion of the Term Loan of any Type may be continued as such upon the expiration of the Interest Period with respect thereto (i) in the case of Base Rate Loans, automatically and (ii) in the case of Libor Rate Loans by compliance by the Borrower with the notice provisions contained in §2.5(a)(i); provided that no Libor Rate Loan may be continued as such when any Default or Event of Default has occurred and is continuing but shall be automatically converted to a Base Rate Loan on the last day of the first Interest Period relating thereto ending during the continuance of any Default or Event of Default. The Borrower shall notify the Agent promptly when any such automatic conversion contemplated by this §2.5(b) is scheduled to occur.

(c) In the event that the Borrower does not notify the Agent of its election hereunder with respect to any portion of the Term Loan in accordance with the terms hereof, such portion of the Term Loan shall be automatically converted to a Base Rate Loan at the end of the applicable Interest Period.

(d) The Borrower may not request or elect a Libor Rate Loan pursuant to §2.4, elect to convert a Base Rate Loan to a Libor Rate Loan pursuant to §2.5(a) or elect to continue a Libor Rate Loan pursuant to §2.5(b) if, after giving effect thereto, there would be greater than five (5) Libor Rate Loans then outstanding. Any Loan Request or Conversion Request for a Libor Rate Loan that would create greater than five (5) Libor Rate Loans outstanding shall be deemed to be a Loan Request or Conversion Request for a Base Rate Loan. By way of explanation of the foregoing, in the event that the Borrower wishes to convert or continue two or more portions of the Term Loan into one Libor Rate Loan on the same day and for identical Interest Periods, such Libor Rate Loan shall constitute one single Libor Rate Loan for purposes of this clause (d).

(e) The Agent will promptly notify each Lender of any Conversion Request received pursuant to §2.5(a) or continuation pursuant to §2.5(b) in accordance with its customary practices.

The notice referred to in the first sentence of this §2.9 shall constitute and shall be deemed to be a certification by the Borrower as to the truth and accuracy of the statements contained in clause (ii) of the preceding sentence. In addition, the Borrower shall deliver to the Agent a Certificate of Compliance certifying compliance with the covenants set forth in §10 as of the date of such Extension.

§3. REPAYMENT OF THE TERM LOAN.

§3.1. Maturity. The Borrower promises to pay on the Maturity Date, and there shall become absolutely due and payable on the Maturity Date, all unpaid principal of the Term Loan outstanding on such date, together with any and all accrued and unpaid interest thereon and any and all other unpaid amounts due under this Agreement, the Notes or any other of the Loan Documents.

§3.2. Optional Repayments of the Term Loan. The Borrower shall have the right, at its election, to prepay the outstanding amount of the Term Loan, in whole or in part, at any time without penalty or premium; provided that the outstanding amount of any Libor Rate Loans may not be prepaid on a date other than the last day of an Interest Period unless the Borrower pays the Libor Breakage Costs for each Libor Rate Loan so prepaid at the time of such prepayment. The Borrower shall give the Agent (with copies to the Agent for each Lender), no later than 10:00 a.m., Cleveland, Ohio time, at least two (2) Business Days’ prior written notice of any prepayment pursuant to this §3.2 of any Base Rate Loans, and at least four (4) Business Days’ notice of any proposed prepayment pursuant to this §3.2 of Libor Rate Loans, specifying the proposed date of prepayment and the principal amount to be prepaid.

§4. CERTAIN GENERAL PROVISIONS.

§4.1. Funds for Payments.

(a) All payments of principal, interest, fees, and any other amounts due hereunder or under any of the other Loan Documents shall be made to the Agent, for the respective accounts of the Lenders or (as the case may be) the Agent, at the Agent’s Head Office, in each case in Dollars and in immediately available funds. The Borrower shall make each payment of principal of and interest on the Term Loan and of fees hereunder not later than 12:00 p.m. (Cleveland, Ohio time) on the due date thereof.

(b) All payments by the Borrower hereunder and under any of the other Loan Documents shall be made without setoff or counterclaim and free and clear of and without deduction for any taxes, levies, imposts, duties, charges, fees, deductions, withholdings, compulsory liens, restrictions or conditions of any nature now or hereafter imposed or levied by any jurisdiction or any political subdivision thereof or taxing or other authority therein unless the Borrower is compelled by law to make such deduction or withholding. If the Borrower is compelled by law to make any such deduction or withholding with respect to any amount payable by it hereunder or under any of the other Loan Documents (except with respect to taxes on the income or profits of the Agent or any Lender), the Borrower shall pay to the Agent, for the account of the Lenders or (as the case may be) the Agent, on the date on which such amount is due and payable hereunder or under such other Loan Document, such additional amount in Dollars as shall be necessary to enable the Lenders to receive the same net amount which the Lenders would have received on such due date had no such deduction or withholding obligation been imposed upon the Borrower. The Borrower will deliver promptly to the Agent (with copies to the Agent for each Lender) certificates or other valid vouchers for all taxes or other charges deducted from or paid with respect to payments made by the Borrower hereunder or under such other Loan Document.

§4.2. Computations. All computations of interest on Libor Rate Loans and of other fees to the extent applicable shall be based on a 360-day year and all computations of interest on Base Rate Loans shall be based on a 365/366 day year, in each case paid for the actual number of days elapsed. Except as otherwise provided in the definition of the term “Interest Period” with respect to Libor Rate Loans, whenever a payment hereunder or under any of the other Loan Documents becomes due on a day that is not a Business Day, the due date for such payment shall be extended to the next succeeding Business Day, and interest shall accrue during such extension. The outstanding amount of the Loans as reflected on the Note Records or record attached to any other Note from time to time shall constitute prima facie evidence of the principal amount thereof.

-28-

§4.3. Inability to Determine Libor Rate. In the event, prior to the commencement of any Interest Period relating to any Libor Rate Loan, the Agent shall determine that adequate and reasonable methods do not exist for ascertaining the Libor Rate that would otherwise determine the rate of interest to be applicable to any Libor Rate Loan during any Interest Period, the Agent shall forthwith give notice of such determination (which shall be conclusive and binding on the Borrower) to the Borrower and the Lenders. In such event (a) any Conversion Request with respect to Libor Rate Loans shall be automatically withdrawn and shall be deemed a request for Base Rate Loans, (b) each Libor Rate Loan will automatically, on the last day of the then current Interest Period applicable thereto, become a Base Rate Loan, and (c) the obligations of the Lenders to make Libor Rate Loans shall be suspended, in each case unless and until the Agent determines that the circumstances giving rise to such suspension no longer exist, whereupon the Agent shall so notify the Borrower and the Lenders.

§4.4. Illegality. Notwithstanding any other provisions herein, if any present or future law, regulation, treaty or directive or in the interpretation or application thereof shall make it unlawful for any Lender to make or maintain Libor Rate Loans, such Lender shall forthwith give notice of such circumstances to the Agent and the Borrower and thereupon (a) the obligation of such Lender to make Libor Rate Loans or convert Base Rate Loans to Libor Rate Loans shall forthwith be suspended and (b) such Lender’s Commitment Percentage of Libor Rate Loans then outstanding shall be converted automatically to Base Rate Loans on the last day of each Interest Period applicable to such Libor Rate Loans or within such earlier period as may be required by law, all until such time as it is no longer unlawful for such Lender to make or maintain Libor Rate Loans. The Borrower hereby agrees promptly to pay the Agent for the account of such Lender, upon demand, any additional amounts necessary to compensate such Lender for Libor Breakage Costs incurred by such Lender in making any conversion required by this §4.4 prior to the last day of an Interest Period.

§4.5. Additional Costs, Etc. If any present or future applicable law, which expression, as used herein, includes statutes, rules and regulations thereunder and interpretations thereof by any competent court or by any governmental or other regulatory body or official charged with the administration or the interpretation thereof and requests, directives, instructions and notices at any time or from time to time hereafter made upon or otherwise issued to any Lender or the Agent by any central bank or other fiscal, monetary or other authority (whether or not having the force of law, but if not having the force of law, then generally applied by the Lenders or the Agent with respect to similar loans), shall:

(a) subject any Lender or the Agent to any tax, levy, impost, duty, charge, fee, deduction or withholding of any nature with respect to this Agreement, the other Loan Documents, such Lender’s Commitment or the Loans (other than taxes based upon or measured by the income or profits of such Lender or the Agent), or

(b) change the basis of taxation (except for changes in taxes on income or profits) of payments to any Lender of the principal of or the interest on the Term Loan or any other amounts payable to the Agent or any Lender under this Agreement or the other Loan Documents, or

-29-

(c) impose or increase or render applicable (other than to the extent specifically provided for elsewhere in this Agreement) any special deposit, reserve, assessment, liquidity, capital adequacy or other similar requirements (whether or not having the force of law) against assets held by, or deposits in or for the account of, or loans by, or letters of credit issued by, or commitments of an office of any Lender, or

(d) impose on any Lender or the Agent any other conditions or requirements with respect to this Agreement, the other Loan Documents, the Loans, such Lender’s Commitment, or any class of loans or commitments of which any of the Loans or such Lender’s Commitment forms a part;

and the result of any of the foregoing is

(i) to increase the cost to any Lender of making, funding, issuing, renewing, extending or maintaining any of the Loans or such Lender’s Commitment, or

(ii) to reduce the amount of principal, interest or other amount payable to such Lender or the Agent hereunder on account of such Lender’s Commitment or any of the Loans, or

(iii) to require such Lender or the Agent to make any payment or to forego any interest or other sum payable hereunder, the amount of which payment or foregone interest or other sum is calculated by reference to the gross amount of any sum receivable or deemed received by such Lender or the Agent from the Borrower hereunder,

then, and in each such case, the Borrower will, upon demand made by the Agent or such Lender (such demand to be made promptly by the Agent or such Lender upon the making of any such determination), at any time and from time to time and as often as the occasion therefor may arise, pay to such Lender or the Agent such additional amounts as such Lender or the Agent shall determine in good faith to be sufficient to compensate such Lender or the Agent for such additional cost, reduction, payment or foregone interest or other sum, provided that such Lender or the Agent is generally imposing similar charges on its other similarly situated borrowers. The Agent shall provide the Borrower with a calculation, in reasonable detail, of such amounts in accordance with its customary practices.

-30-

§4.6. Capital Adequacy. If any future law, governmental rule, regulation, policy, guideline or directive (whether or not having the force of law, but if not having the force of law, then generally applied by the Lenders with respect to similar loans) or the interpretation thereof by a court or governmental authority with appropriate jurisdiction affects the amount of capital required or expected to be maintained by banks or bank holding companies and any Lender or the Agent determines that the amount of capital required to be maintained by it is increased by or based upon the existence of Loans made or deemed to be made pursuant hereto, then such Lender or the Agent may notify the Borrower of such fact, and the Borrower shall pay to such Lender or the Agent from time to time, upon demand made by the Agent or such Lender (such demand to be made promptly by the Agent or such Lender upon the making of any such determination), as an additional fee payable hereunder, such amount as such Lender or the Agent shall determine reasonably and in good faith and certify in a notice to the Borrower to be an amount that will adequately compensate such Lender in light of these circumstances for its increased costs of maintaining such capital. Each Lender and the Agent shall allocate such cost increases among its customers in good faith and on an equitable basis, and will not charge the Borrower unless it is generally imposing a similar charge on its other similarly situated borrowers. The Agent shall provide the Borrower with a calculation, in reasonable detail, of such amounts in accordance with its customary practices.

§4.7. Certificate; Limitations. A certificate setting forth any additional amounts payable pursuant to §§4.5 or 4.6 and a brief explanation of such amounts which are due, submitted by any Lender or the Agent to the Borrower, shall be prima facie evidence that such amounts are due and owing. Notwithstanding anything to the contrary contained in this Article 4, to the extent reasonably possible, each Lender shall designate an alternate lending office in the continental United States to make the Loans in order to reduce any liability of Borrower to such Lender under §§4.4, 4.5 or 4.6 or to avoid the unavailability of a Libor Rate Loan, so long as such designation is not disadvantageous to such Lender.

§4.8. Indemnity. In addition to the other provisions of this Agreement regarding such matters, the Borrower agrees to indemnify the Agent and each Lender and to hold the Agent and each Lender harmless from and against any loss, cost or expense (including loss of anticipated profits) that the Agent or such Lender may sustain or incur as a consequence of (a) a default by the Borrower in the payment of any principal amount of or any interest on any Libor Rate Loans as and when due and payable, including any such loss or expense arising from interest or fees payable by the Agent or such Lender to lenders of funds obtained by it in order to maintain its Libor Rate Loans, (b) the failure by the Borrower to make a borrowing or conversion after the Borrower has given the Completed Loan Request for a Libor Rate Loan or a Conversion Request for a Libor Rate Loan, and (c) the making of any payment of a Libor Rate Loan or the making of any conversion of any such Loan to a Base Rate Loan on a day that is not the last day of the applicable Interest Period with respect thereto, including interest or fees payable by the Agent or a Lender to lenders of funds obtained by it in order to maintain any such Libor Rate Loans.

-31-

§4.9. Interest on Overdue Amounts; Late Charge. Notwithstanding anything to the contrary stated herein, upon the occurrence and during the continuance of an Event of Default, at the option of the Majority Lenders, to the extent permitted by applicable law, the unpaid balance of all Obligations shall bear interest at the rate otherwise applicable thereto plus 2%, compounded daily until such Event of Default is cured or waived to the satisfaction of the Agent and the required Lenders. In addition, the Borrower shall pay a late charge equal to five percent (5%) of any amount of interest charges on the Term Loan which is not paid within ten (10) days of the date when due.

§5. COLLATERAL

§5.1. Security Interests. The Obligations shall be secured by (i) a perfected first-priority lien on, or security title and security interest to be held by the Agent for the benefit of the Lenders in, the Collateral, which Collateral shall include the Pledged Equity Interests, and (ii) such additional collateral, if any, as the Agent, for the benefit of the Lenders from time to time may accept as security for the Obligations. The Obligations shall also be guaranteed pursuant to the terms of the Trust Guaranty and the Subsidiary Guaranties.

§6. RECOURSE OBLIGATIONS; JOINT AND SEVERAL LIABILITY.

-71-

Notwithstanding the foregoing provisions of this §14.1, in the event of a Default or Event of Default arising as a result of the inclusion of any Real Estate Asset in the Borrowing Base Pool at any particular time of reference, if such Default or Event of Default is capable of being cured by the exclusion of such Real Estate Asset from the Borrowing Base Pool in accordance with, and subject to, §8.13 and from all other covenant calculations under §10 or otherwise, the Borrower shall be permitted a period not to exceed five (5) days to submit to the Agent (with copies to the Agent for each Lender) a compliance certificate in the form of Exhibit C hereto evidencing compliance with the covenants set forth in §10 (with calculations evidencing such compliance after excluding from Adjusted Net Operating Income all of the Adjusted Net Operating Income generated by the Real Estate Asset to be excluded from the Borrowing Base Pool) and with the Borrowing Base Property Conditions, and otherwise certifying that, after giving effect to the exclusion of such Real Estate Asset from the Borrowing Base Pool, no Default or Event of Default will be continuing.

§14.2. [Reserved.]

No remedy herein conferred upon the Lenders or the Agent or the holder of any Note is intended to be exclusive of any other remedy and each and every remedy shall be cumulative and shall be in addition to every other remedy given hereunder or under any of the other Loan Documents or now or hereafter existing at law or in equity or by statute or any other provision of law.

§15. SECURITY INTEREST AND SET-OFF.

§15.1 Security Interest. Borrower hereby grants to the Agent, on behalf of and for the benefit of the Lenders, and to each Lender, a lien, security interest and right of setoff as security for all liabilities and obligations to the Lenders, whether now existing or hereafter arising, upon and against all deposits, credits, collateral and property, now or hereafter in the possession, custody, safekeeping or control of the Agent or any Lender or any entity under the control of KeyCorp. and its successors and assigns, or in transit to any of them.

-72-

§15.2 Set-Off and Debit. (i) If any Event of Default or other event which would entitle the Agent to accelerate the Term Loan occurs, or (ii) at any time, whether or not any Default or Event of Default exists, in the event any attachment, trustee process, garnishment, or other levy or lien is, or is sought to be, imposed on any property of the Borrower or a Subsidiary Guarantor; then, in any such event, any such deposits, balances or other sums credited by or due from the Agent or any Lender, or from any such affiliate of the Agent or any Lender, to the Borrower or a Subsidiary Guarantor may to the fullest extent not prohibited by applicable law at any time or from time to time, without regard to the existence, sufficiency or adequacy of any other collateral, and without notice or compliance with any other condition precedent now or hereafter imposed by statute, rule of law or otherwise, all of which are hereby waived, be set off, debited and appropriated, and applied by the Agent or any Lender, as the case may be, against any or all of the Obligations irrespective of whether demand shall have been made and although such Obligations may be unmatured, in such manner as the Agent or the applicable Lender in its sole and absolute discretion may determine. Within five (5) Business Days of making any such set off, debit or appropriation and application, the Agent agrees to notify the Borrower thereof, provided that the failure to give such notice shall not affect the validity of such set off, debit or appropriation and application. ANY AND ALL RIGHTS TO REQUIRE THE AGENT OR ANY LENDER TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE LOANS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE BORROWER, ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED. Each of the Lenders agrees with each other Lender that (a) if an amount to be set off is to be applied to indebtedness of the Borrower to such Lender, other than the obligations evidenced by the Note held by such Lender, such amount shall be applied ratably to such other indebtedness and to the obligations evidenced by the Note held by such Lender, and (b) if such Lender shall receive from the Borrower, whether by voluntary payment, exercise of the right of setoff, counterclaim, cross action, enforcement of the claim evidenced by the Note held by such Lender by proceedings against the Borrower or a Subsidiary Guarantor at law or in equity or by proof thereof in bankruptcy, reorganization liquidation, receivership or similar proceedings, or otherwise, and shall retain and apply to the payment of the Note held by such Lender any amount in excess of its ratable portion of the payments received by all of the Lenders with respect to the Note held by all of the Lenders, such Lender will make such disposition and arrangements with the other Lenders with respect to such excess, either by way of distribution, pro tanto assignment of claims, subrogation or otherwise as shall result in each Lender receiving in respect of the Note held by it its proportionate payment as contemplated by this Agreement; provided that if all or any part of such excess payment is thereafter recovered from such Lender, such disposition and arrangements shall be rescinded and the amount restored to the extent of such recovery, but without interest.

-73-

§15.3 Right to Freeze. The Agent and each of the Lenders shall also have the right, at its option, upon the occurrence of any event which would entitle the Agent or any Lender to set off or debit as set forth in §15.2, to freeze, block or segregate any such deposits, balances and other sums so that the Borrower and the Subsidiary Guarantors may not access, control or draw upon the same.

§15.4 Additional Rights. The rights of the Agent, the Lenders and each affiliate of Agent and each of the Lenders under this Section 15 are in addition to, and not in limitation of, other rights and remedies, including other rights of set off, which the Agent or any Lender may have.

§16. THE AGENT.

§16.1. Authorization. (a) The Agent is authorized to take such action on behalf of each of the Lenders and to exercise all such powers as are hereunder and under any of the other Loan Documents and any related documents delegated to the Agent, together with such powers as are reasonably incident thereto, provided that no duties or responsibilities not expressly assumed herein or therein shall be implied to have been assumed by the Agent. The relationship between the Agent and the Lenders is and shall be that of agent and principal only, and nothing contained in this Agreement or any of the other Loan Documents shall be construed to constitute the Agent as a trustee or fiduciary for any Lender.

(b) The Borrower, without further inquiry or investigation, shall, and is hereby authorized by the Lenders to, assume that all actions taken by the Agent hereunder and in connection with or under the Loan Documents are duly authorized by the Lenders. The Lenders shall notify Borrower of any successor to Agent by a writing signed by Majority Lenders, which successor shall be reasonably acceptable to the Borrower so long as no Default or Event of Default has occurred and is continuing. The Borrower acknowledges that any Lender which acquires KeyBank is acceptable as a successor to the Agent.

§16.2. Employees and Agents. The Agent may exercise its powers and execute its duties by or through employees or agents and shall be entitled to take, and to rely on, advice of counsel concerning all matters pertaining to its rights and duties under this Agreement and the other Loan Documents. The Agent may utilize the services of such Persons as the Agent in its sole discretion may reasonably determine, and all reasonable fees and expenses of any such Persons shall be paid by the Borrower.

§16.3. No Liability. Neither the Agent, nor any of its shareholders, directors, officers or employees nor any other Person assisting them in their duties nor any agent or employee thereof, shall be liable for any waiver, consent or approval given or any action taken, or omitted to be taken, in good faith by it or them hereunder or under any of the other Loan Documents, or in connection herewith or therewith, or be responsible for the consequences of any oversight or error of judgment whatsoever, except that the Agent may be liable for losses due to its willful misconduct or gross negligence, as finally determined by a court of competent jurisdiction.

-74-

§16.4. No Representations. The Agent shall not be responsible for the execution or validity or enforceability of this Agreement, the Notes or any of the other Loan Documents or for the validity, enforceability or collectibility of any such amounts owing with respect to the Notes, or for any recitals or statements, warranties or representations made herein or in any of the other Loan Documents or in any certificate or instrument hereafter furnished to it by or on behalf of the Trust or the Borrower or any of their respective Subsidiaries, or be bound to ascertain or inquire as to the performance or observance of any of the terms, conditions, covenants or agreements in this Agreement or the other Loan Documents. The Agent shall not be bound to ascertain whether any notice, consent, waiver or request delivered to it by the Borrower, a Subsidiary Guarantor or the Trust or any holder of any of the Notes shall have been duly authorized or is true, accurate and complete. The Agent has not made nor does it now make any representations or warranties, express or implied, nor does it assume any liability to the Lenders, with respect to the credit worthiness or financial condition of the Borrower or a Subsidiary Guarantor or any of their respective Subsidiaries or the Trust or any of the Subsidiaries or any tenant under a Lease or any other entity. Each Lender acknowledges that it has, independently and without reliance upon the Agent or any other Lender, and based upon such information and documents as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement.

§16.5. Payments.

(a) A payment by the Borrower to the Agent hereunder or any of the other Loan Documents for the account of any Lender shall constitute a payment to such Lender on the date received, if before 1:00 p.m. (Cleveland, Ohio time), and if after 1:00 p.m. (Cleveland, Ohio time), on the next Business Day. The Agent agrees to distribute to each Lender such Lender’s pro rata share of payments received by the Agent for the accounts of all the Lenders, as provided herein or in any of the other Loan Documents. All such payments by the Agent to the Lenders shall be made on the date received, if before 1:00 p.m., and if after 1:00 p.m., on the next Business Day.

(b) If in the reasonable opinion of the Agent the distribution of any amount received by it in such capacity hereunder, under the Notes or under any of the other Loan Documents might involve it in material liability, it may refrain from making distribution until its right to make distribution shall have been adjudicated by a court of competent jurisdiction, provided that the Agent shall invest any such undistributed amounts in overnight obligations on behalf of the Lenders and interest thereon shall be paid pro rata to the Lenders. If a court of competent jurisdiction shall adjudge that any amount received and distributed by the Agent is to be repaid, each Person to whom any such distribution shall have been made shall either repay to the Agent its proportionate share of the amount so adjudged to be repaid or shall pay over the same in such manner and to such Persons as shall be determined by such court.

-75-

(c) Notwithstanding anything to the contrary contained in this Agreement or any of the other Loan Documents, any Lender that fails (i) to make available to the Agent its pro rata share of the Term Loan or (ii) to adjust promptly such Lender’s outstanding principal and its pro rata Commitment Percentage as provided in §2.1, shall be deemed delinquent (a “Delinquent Lender”) and shall be deemed a Delinquent Lender until such time as such delinquency is satisfied. A Delinquent Lender shall be deemed to have assigned any and all payments due to it from the Borrower, whether on account of the outstanding Term Loan, interest, fees or otherwise, to the remaining nondelinquent Lenders for application to, and reduction of, their respective pro rata shares of all outstanding Loans. The Delinquent Lender hereby authorizes the Agent to distribute such payments to the nondelinquent Lenders in proportion to their respective pro rata shares of the outstanding Term Loan. If not previously satisfied directly by the Delinquent Lender, a Delinquent Lender shall be deemed to have satisfied in full a delinquency when and if, as a result of application of the assigned payments to the outstanding Term Loan of the nondelinquent Lenders, the Lenders’ respective pro rata shares of the outstanding Term Loan have returned to those in effect immediately prior to such delinquency and without giving effect to the nonpayment causing such delinquency. The Commitment of any Delinquent Lender shall be excluded for purposes of making a determination of Majority Lenders or Unanimous Lender Approval. At the written request of the Borrower, the Agent or, with the consent of the Agent, any Lender or an Eligible Assignee, shall have the right (but not the obligation) to purchase from any Delinquent Lender, and each Delinquent Lender shall, upon such request, sell and assign to the Agent, such Lender or such Eligible Assignee, all of the Delinquent Lender’s outstanding Term Loan hereunder. Such sale shall be consummated promptly after the Agent has arranged for a purchase by the Agent, a Lender or an Eligible Assignee pursuant to an Assignment and Assumption, and at a price equal to the outstanding principal balance of the Delinquent Lender’s Term Loan plus accrued interest and fees, without premium or discount.

§16.6. Holders of Notes. The Agent may deem and treat the payee of any Notes as the absolute owner or purchaser thereof for all purposes hereof until it shall have been furnished in writing with a different name by such payee or by a subsequent holder, assignee or transferee.

§16.7. Indemnity. The Lenders ratably and severally agree hereby to indemnify and hold harmless the Agent and its Affiliates from and against any and all claims, actions and suits (whether groundless or otherwise), losses, damages, costs, expenses (including any expenses for which the Agent has not been reimbursed by the Borrower as required by §17), and liabilities of every nature and character arising out of or related to this Agreement, the Notes, or any of the other Loan Documents or the transactions contemplated or evidenced hereby or thereby, or the Agent’s actions taken hereunder or thereunder, except to the extent that any of the same shall be directly caused by the Agent’s willful misconduct or gross negligence, as finally determined by a court of competent jurisdiction.

-76-

§16.8. Agent as Lender. In its individual capacity as a Lender, KeyBank shall have the same obligations and the same rights, powers and privileges in respect to its Commitment and the Term Loan made by it, and as the holder of any of the Notes, as it would have were it not also the Agent.

§16.9. Notification of Defaults and Events of Default. Each Lender hereby agrees that, upon learning of the existence of a Default or an Event of Default, it shall (to the extent notice has not previously been provided) promptly notify the Agent thereof. The Agent hereby agrees that upon receipt of any notice under this §16.9 it shall promptly notify the other Lenders of the existence of such Default or Event of Default.

§16.10. Duties in Case of Enforcement. In the case one or more Events of Default have occurred and shall be continuing, and whether or not acceleration of the Obligations shall have occurred, the Agent shall, at the request, or may, upon the consent, of the Majority Lenders, and provided that the Lenders have given to the Agent such additional indemnities and assurances against expenses and liabilities as the Agent may reasonably request, proceed to enforce the provisions of this Loan Agreement and the other Loan Documents and the exercise of any other legal or equitable rights or remedies as it may have hereunder or under any other Loan Document or otherwise by virtue of applicable law, or to refrain from so acting if similarly requested by the Majority Lenders. The Agent shall be fully protected in so acting or refraining from acting upon the instruction of the Majority Lenders, and such instruction shall be binding upon all the Lenders. The Majority Lenders may direct the Agent in writing as to the method and the extent of any such foreclosure, sale or other disposition or the exercise of any other right or remedy, the Lenders hereby agreeing to severally indemnify and hold the Agent harmless from all costs and liabilities incurred in respect of all actions taken or omitted in accordance with such direction, provided that the Agent need not comply with any such direction to the extent that the Agent reasonably believes the Agent’s compliance with such direction may expose the Agent to liability or be contrary to the Loan Documents or applicable law. The Agent may, in its discretion but without obligation, in the absence of direction from the Majority Lenders, take such interim actions as it believes reasonably necessary to preserve the rights of the Lenders hereunder, including but not limited to petitioning a court for injunctive relief or appointment of a receiver. Each of the Lenders acknowledges and agrees that, except for any rights of set-off pursuant to and in accordance with §15.2 hereof, no individual Lender may separately enforce or exercise any of the provisions of any of the Loan Documents, including without limitation the Notes, other than through the Agent. The Agent shall advise the Lenders of all such action taken by the Agent.

-77-

§16.11. Successor Agent. KeyBank, or any successor Agent, may resign as Agent at any time by giving at least 30 days prior written notice thereof to the Lenders and to the Borrower. Any such resignation shall be effective upon appointment and acceptance of a successor Agent, as hereinafter provided. Upon any such resignation, the Majority Lenders shall have the right to appoint a successor Agent, which is a Lender under this Agreement, provided that so long as no Default or Event of Default has occurred and is continuing the Borrower shall have the right to approve any successor Agent, which approval shall not be unreasonably withheld. If, in the case of a resignation by the Agent, no successor Agent shall have been so appointed by the Majority Lenders and approved by the Borrower, and shall have accepted such appointment, within thirty (30) days after the retiring Agent’s giving of notice of resignation, then the retiring Agent may, on behalf of the Lenders, appoint any one of the other Lenders as a successor Agent. The Borrower acknowledges that any Lender which acquires KeyBank is acceptable as a successor Agent. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from all further duties and obligations as Agent under this Agreement. After any Agent’s resignation hereunder as Agent, the provisions of this §16 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement. The Agent agrees that it shall not assign any of its rights or duties as Agent to any other Person. The Agent may be removed at the direction of the Majority Lenders in the event of a final judicial determination (in which the Agent had an opportunity to be heard) that the Agent had acted in a grossly negligent manner or in willful misconduct.

§16.12. Notices. Any notices or other information required hereunder to be provided to the Agent (with copies to the Agent for each Lender) shall be promptly forwarded by the Agent to each of the Lenders.

§17. EXPENSES. The Borrower agrees to pay (a) the reasonable costs of producing and reproducing this Agreement, the other Loan Documents and the other agreements and instruments mentioned herein, (b) the reasonable fees, expenses and disbursements of the Agent’s outside counsel or any local counsel to the Agent incurred in connection with the preparation, administration or interpretation of the Loan Documents and other instruments mentioned herein, each closing hereunder, and amendments, modifications, approvals, consents or waivers hereto or hereunder, (c) the fees, expenses and disbursements of the Agent incurred by the Agent in connection with the preparation, administration or interpretation of the Loan Documents and other instruments mentioned herein, including, without limitation, the costs incurred by the Agent in connection with its inspection of the Eligible Borrowing Base Properties, and, without double-counting amounts under clause (b) above, the fees and disbursements of the Agent’s counsel in preparing the documentation, (d) the fees, costs, expenses and disbursements of the Agent and its Affiliates incurred in connection

-78-

with the syndication and/or participations of the Term Loan (whether occurring before or after the closing hereunder), including, without limitation, reasonable legal fees, travel costs, costs of preparing syndication materials and photocopying costs, (e) all reasonable expenses (including reasonable attorneys’ fees and costs, which attorneys may be employees of any Lender or the Agent, and the fees and costs of engineers, appraisers, surveyors, investment bankers, or other experts retained by any Lender or the Agent in connection with any such enforcement proceedings) incurred by any Lender or the Agent in connection with (i) the enforcement of or preservation of rights under any of the Loan Documents against the Borrower, any Subsidiary Guarantor or any of their Subsidiaries or the Trust or the administration thereof after the occurrence and during the continuance of a Default or Event of Default (including, without limitation, expenses incurred in any restructuring and/or “workout” of the Term Loan), and (ii) any litigation, proceeding or dispute whether arising hereunder or otherwise, in any way related to any Lender’s or the Agent’s relationship with the Borrower, any Subsidiary Guarantor or any of their respective Subsidiaries or the Trust, (f) all reasonable fees, expenses and disbursements of the Agent incurred in connection with UCC searches and filings, UCC terminations or mortgage discharges, or otherwise in connection with the Collateral, and (g) all costs incurred by the Agent in the future in connection with its inspection of the Eligible Borrowing Base Properties (or any proposed Eligible Borrowing Base Property) or with the addition of any Eligible Borrowing Base Property. The covenants of this §17 shall survive the repayment of the amounts owing under the Notes and this Agreement and the termination of this Agreement and the obligations of the Lenders hereunder.

§18. INDEMNIFICATION. The Borrower agrees to indemnify and hold harmless the Agent and each of the Lenders and the shareholders, directors, agents, officers, subsidiaries and affiliates of the Agent and each of the Lenders from and against any and all claims, actions and suits, whether groundless or otherwise, and from and against any and all liabilities, losses (including amounts, if any, owing to any Lender pursuant to §§4.4, 4.5, 4.6 and 4.8), settlement payments, obligations, damages and expenses of every nature and character in connection therewith, arising out of this Agreement or any of the other Loan Documents or the transactions contemplated hereby or thereby or which otherwise arise in connection with the financing, including, without limitation, (a) any actual or proposed use by the Borrower or any of its Subsidiaries of the proceeds of any of the Term Loans (b) the Borrower or any of its Subsidiaries entering into or performing this Agreement or any of the other Loan Documents, or (c) pursuant to §8.16, in each case including, without limitation, the reasonable fees and disbursements of counsel and allocated costs of internal counsel incurred in connection with any such investigation, litigation or other proceeding, provided, however, that the Borrower shall not be obligated under this §18 to indemnify any Person for liabilities arising from such Person’s own gross negligence, willful misconduct or breach of this Agreement, as finally determined by a court of competent jurisdiction. In litigation, or the preparation therefor, the Borrower shall be entitled to select counsel reasonably acceptable to the Majority Lenders, and the Agent (as approved by the Majority Lenders) shall be entitled to select their own supervisory counsel, and, in addition to the foregoing indemnity, the Borrower agrees to pay

-79-

promptly the reasonable fees and expenses of each such counsel. Prior to any settlement of any such litigation by the Lenders, the Lenders shall provide the Borrower and the Trust with notice and an opportunity to address any of their concerns with the Lenders, and the Lenders shall not settle any litigation without first obtaining Borrower’s consent thereto, which consent shall not be unreasonably withheld or delayed, provided that such consent shall not be required at any time that an Event of Default has occurred and is continuing. If and to the extent that the obligations of the Borrower under this §18 are unenforceable for any reason, the Borrower hereby agrees to make the maximum contribution to the payment in satisfaction of such obligations which is permissible under applicable law. The provisions of this §18 shall survive the repayment of the amounts owing under the Notes and this Agreement and the termination of this Agreement and the obligations of the Lenders hereunder and shall continue in full force and effect as long as the possibility of any such claim, action, cause of action or suit exists.

Schedule 3

950 F Street Investment

FPLP, through a subsidiary, is proposing to make a preferred equity investment in a single purpose entity limited liability company owned by Douglas Jemal (the “Jemal LLC”) and certain of his relatives and affiliates. The Jemal LLC is the sole and managing member of a single purpose entity limited liability company (the “Property Owner LLC”) that owns an office building located at 950 F Street, NW, Washington, DC. The amount of the proposed investment is twenty-five million dollars ($25,000,000), and FPLP will be entitled to a preferred return of 12.5% per annum (17.5% in the event of a default or after seven years). The Jemal LLC must also maintain a cash reserve account in an amount equal to 6 monthly payments of the preferred return. The preferred interest is redeemable by the Jemal LLC at any time after the third anniversary of issuance. Prior to that time, the preferred interest may only be redeemed upon a sale of the property with the consent of FPLP and with the payment of a make-whole premium. The preferred interest will become redeemable at the option of FPLP beginning in 2018. In the event that the Property Owner LLC defaults in the payment of any preferred return or if the Property Owner LLC defaults on its mortgage loan in the original principal amount of One Hundred Fifty Million Dollars ($150,000,000), FPLP will have the right to cause the Jemal LLC to redeem the common equity at 80% of fair market value, at which time FPLP will become the sole member of Jemal LLC. FPLP as preferred member will also have the customary major decision veto rights.

(1)	The loan was repaid in January 2011 with available cash.
(2)	The loan was repaid in July 2011 with borrowings from the Company’s unsecured revolving credit facility.
(3)	The maturity date presented for the loan represents the anticipated repayment date of the loan, after which date the interest rate on the loan will increase to a predetermined amount identified in the debt agreement. The effective interest rate was calculated based on the anticipated period the debt is expected to be outstanding.
(4)	The loan was repaid in April 2011 with available cash.
(5)	Weighted average interest rate on total mortgage debt.

On April 8, 2011, the Company acquired One Fair Oaks in Fairfax, Virginia. The acquisition was funded by the assumption of a $52.4 million mortgage loan and available cash. The mortgage loan has a fixed contractual interest rate of 6.31% and matures in June 2012.

(b) Unsecured Term Loan

On July 18, 2011, the Company entered into a three-tranche $175.0 million unsecured term loan. The unsecured term loan’s three tranches have maturity dates staggered in one-year intervals. Tranche A has an outstanding balance of $60.0 million at an interest rate of LIBOR plus 215 basis points and matures on July 18, 2016. Tranche B has an outstanding balance of $60.0 million at an interest rate of LIBOR plus 225 basis points and matures on July 18, 2017. Tranche C has an outstanding balance of $55.0 million at an interest rate of LIBOR plus 230 basis points and matures on July 18, 2018. The term loan agreement contains various restrictive covenants substantially similar to those contained in the Company’s revolving credit facility, including with respect to liens, indebtedness, investments, distributions, mergers and asset sales. In addition, the agreement requires that the Company satisfy certain financial covenants that are also substantially similar to those contained in the Company’s revolving credit facility. The agreement also includes customary events of default, the occurrence of which, following any applicable cure period, would permit the lenders to, among other things, declare the principal, accrued interest and other obligations of the Company under the agreement to be immediately due and payable. The Company used the funds to pay down $117.0 million of the outstanding balance on its unsecured revolving credit facility, to repay its $50.0 million senior secured term loan and for other general corporate purposes.

(c) Unsecured Revolving Credit Facility

During the second quarter of 2011, the Company amended and restated its unsecured revolving credit facility. Under the new agreement, the capacity on the Company’s unsecured revolving credit facility was expanded from $225.0 million to $255.0 million and the maturity date was extended to January 2014 with a one-year extension at the Company’s option, which it intends to exercise. The interest rate on the unsecured revolving credit facility decreased from a range of LIBOR plus 275 to 375 basis points to a range of LIBOR plus 200 to 300 basis points, depending on the Company’s overall leverage. At June 30, 2011, LIBOR was 0.19%. The Company’s ability to borrow under the credit facility will be subject to its satisfaction of certain financial covenants and its ongoing compliance with various restrictive covenants similar to those included in the prior credit facility, including with respect to liens, indebtedness, investments, distributions, mergers and asset sales. The credit facility includes customary events of default, the occurrence of which, following any applicable cure period, would permit the lenders to, among other things, declare the principal, accrued interest and other obligations of the Company under the credit facility to be immediately due and payable.

During the second quarter of 2011, the Company borrowed $48.0 million on its unsecured revolving credit facility to provide a subordinated loan to the owners of America’s Square and for general corporate purposes. For the three and six months ended June 30, 2011, the Company’s weighted average borrowings outstanding on its unsecured revolving credit facility was $151.1 million and $132.9 million, respectively, with a weighted average interest rate of 3.1% and 3.2%, respectively, compared with $84.5 million and $117.9 million with a weighted average interest rate of 3.6% and 3.8% for the three and six months ended June 30, 2010, respectively. At June 30, 2011, outstanding borrowings under the unsecured revolving credit facility were $164.0 million. The Company is required to pay an annual commitment fee of 0.25% based on the amount of unused capacity under the unsecured revolving credit facility, which was $91.0 million at June 30, 2011.

(d) Debt Covenants

At June 30, 2011, the Company was in compliance with all of the financial and non-financial covenants associated with its debt instruments with the exception of the mortgage loans explained below.

Certain of the Company’s subsidiaries are borrowers on mortgage loans, the terms of which prohibit certain direct or indirect transfers of ownership interests in the borrower subsidiary (a “Prohibited Transfer”). Under the terms of the mortgage loan documents, a lender could assert that a Prohibited Transfer includes the trading of the Company’s common shares on the NYSE, the issuance of common shares by the Company, or the issuance of units of limited partnership interest in the Operating Partnership. As of June 30, 2011, the Company believes that there were eight mortgage loans with such Prohibited Transfer provisions, representing an aggregate principal amount outstanding of approximately $77 million. Two of these mortgage loans were entered into prior to the Company’s initial public offering (“IPO”) in 2003 and six were assumed subsequent to its IPO. In July 2011, the Company repaid two mortgages totaling $19.7 million with Prohibited Transfer provisions that were both assumed subsequent to its IPO. In each instance, the Company received the consent of the mortgage lender to consummate its IPO (for the two pre-IPO loans) or to acquire the property or the ownership interests of the borrower (for the post-IPO loans), including the assumption by its subsidiary of the mortgage loan. Generally, the underlying mortgage documents, previously applicable to a privately held owner, were not changed at the time of the IPO or the later loan assumptions, although the Company believes that each of the lenders or servicers was aware that the borrower’s ultimate parent was or would become a publicly traded company. Subsequent to the IPO and the assumption of these additional mortgage loans, the Company has issued new common shares and shares of the Company have been transferred on the New York Stock Exchange. Similarly, the Operating Partnership has issued units of limited partnership interest. To date, no lender or servicer has asserted that a Prohibited Transfer has occurred as a result of any such transfer of shares or units of limited partnership interest. If a lender were to be successful in any such action, the Company could be required to immediately repay or refinance the amounts outstanding, or the lender may be able to foreclose on the property securing the loan or take other adverse actions. In addition, in certain cases a Prohibited Transfer could result in the loan becoming fully recourse to the Company or its Operating Partnership. In addition, if a violation of a Prohibited Transfer provision were to occur that would permit the Company’s mortgage lenders to accelerate the indebtedness owed to them, it could result in an event of default under the Company’s Senior Unsecured Series A and Series B Notes, its unsecured revolving credit facility, its senior secured term loan, its two Secured Term Loans and its Exchangeable Senior Notes.

Noncontrolling Interests in Partnerships [Abstract]

Noncontrolling Interests in Partnerships

(12) Noncontrolling Interests in Partnerships

(a) Noncontrolling Interests in Operating Partnership

Noncontrolling interests relate to the interests in the Operating Partnership not owned by the Company. Interests in the Operating Partnership are owned by limited partners who contributed buildings and other assets to the Operating Partnership in exchange for Operating Partnership units. Limited partners have the right to tender their units for redemption in exchange for, at the Company’s option, common shares of the Company on a one-for-one basis or cash based on the fair value of the Company’s common shares at the date of redemption. Unitholders receive a distribution per unit equivalent to the dividend per common share. Differences between amounts paid to redeem noncontrolling interests and their carrying values are charged or credited to equity. As a result of the redemption feature of the Operating Partnership units, the noncontrolling interests are recorded outside of permanent equity. Noncontrolling interests are presented at the greater of their fair value or their cost basis, which is comprised of their fair value at issuance, subsequently adjusted for the noncontrolling interests’ share of net income, losses, distributions received, preferred dividends paid or additional contributions. Based on the closing share price of the Company’s common stock at June 30, 2011, the cost to acquire, through cash purchase or issuance of the Company’s common shares, all of the outstanding Operating Partnership units not owned by the Company would be approximately $36.4 million, which exceeded the noncontrolling interests’ historical cost by $3.2 million.

At December 31, 2010, 958,473 Operating Partnership units, or 1.9%, were not owned by the Company. During the six months ended June 30, 2011, the Company issued 1,418,715 Operating Partnership units valued at $21.7 million to partially fund the acquisition of 840 First Street, NE. There were also 1,300 Operating Partnership units redeemed for 1,300 common shares fair valued at $19 thousand. As a result, 2,375,888 of the total outstanding Operating Partnership units, or 4.5%, were not owned by the Company at June 30, 2011. There were no Operating Partnership units redeemed with available cash during the six months ended June 30, 2011.

(b) Noncontrolling Interests in Consolidated Partnerships

When the Company is deemed to have a controlling interest in a partially-owned entity, it will consolidate all of the entity’s assets, liabilities and operating results within its consolidated financial statements. The cash contributed to the consolidated entity by the third party, if any, will be reflected in the permanent equity section of the Company’s consolidated balance sheets to the extent they are not mandatorily redeemable. The amount will be recorded based on the third party’s initial investment in the consolidated entity and will be adjusted to reflect the third party’s share of earnings or losses in the consolidated entity and for any distributions received or additional contributions made by the third party. The earnings or losses from the entity attributable to the third party are recorded as a component of net loss (income) attributable to noncontrolling interests.

On November 10, 2010, the Company acquired Redland Corporate Center II and III through a joint venture with Perseus Realty, LLC (“Perseus”). As a result of the partnership structure, the Company has a 97% economic interest in the joint venture and Perseus has the remaining 3% interest. As of June 30, 2011, the Company recorded noncontrolling interests of $3.1 million, which reflects the third party’s common equity interest in Redland Corporate Center II & III.

On January 25, 2011, the Company formed a joint venture with an affiliate of The Akridge Company (“Akridge”) to acquire, for $39.6 million, a property located at 1200 17th Street, NW, in Washington, DC, and to redevelop the property. The property currently consists of a land parcel that contains an existing 85,000 square foot office building. The joint venture intends to demolish the existing building and develop a new Class A office building expected to have approximately 170,000 square feet of gross leasable area. When the joint venture is fully capitalized, the Company anticipates owning 95% of the joint venture (subject to adjustment depending on each party’s capital contributions and subject to a promoted interest granted to Akridge after specified returns are achieved by the Company). The Company’s total capital commitment to the joint venture (including acquisition and development costs) is anticipated to be approximately $109 million, less amounts funded through acquisition and construction financing. The acquisition of the property is not expected to occur until late 2011 and is subject to various contingencies. Construction is currently expected to commence in 2012 and is expected to be completed in late 2014. As of June 30, 2011, the Company recorded noncontrolling interests of $1.0 million, which reflects the third party’s common equity interest in 1200 17th Street, NW.

Earnings Per Share [Abstract]

Earnings Per Share

(3) Earnings Per Share

Basic earnings or loss per share (“EPS”) is calculated by dividing net income or loss available to common shareholders by the weighted average common shares outstanding for the period. Diluted EPS is computed after adjusting the basic EPS computation for the effect of dilutive common equivalent shares outstanding during the period, which include stock options, non-vested shares, preferred shares and Exchangeable Senior Notes. The Company applies the two-class method for determining EPS as its outstanding unvested shares with non-forfeitable dividend rights are considered participating securities. The Company’s excess of distributions over earnings related to participating securities are shown as a reduction in total earnings attributable to common shareholders in the Company’s computation of EPS.

The following table sets forth the computation of the Company’s basic and diluted earnings per share (amounts in thousands, except per share amounts):

Derivative Instruments and Comprehensive Income (Loss) [Abstract]

Derivative Instruments and Comprehensive Income (Loss)

(9) Derivative Instruments and Comprehensive Income (Loss)

The Company is exposed to certain risks arising from business operations and economic factors. The Company uses derivative financial instruments to manage exposures that arise from business activities in which its future exposure to interest rate fluctuations is unknown. The objective in the use of an interest rate derivative is to add stability to interest expenses and manage exposure to interest rate changes. No hedging activity can completely insulate the Company from the risks associated with changes in interest rates. Moreover, interest rate hedging could fail to protect the Company or adversely affect it because, among other things:

• available interest rate hedging may not correspond directly with the interest rate risk for which the Company seeks protection;

• the duration of the hedge may not match the duration of the related liability;

• the party owing money in the hedging transaction may default on its obligation to pay; and

• the credit quality of the party owing money on the hedge may be downgraded to such an extent that it impairs the Company’s ability to sell or assign its side of the hedging transaction.

The Company enters into interest rate swap agreements to hedge its exposure on its variable rate debt against fluctuations in prevailing interest rates. The interest rate swap agreements fix LIBOR to a specified interest rate, however, the swap agreements do not affect the contractual spreads associated with each variable debt instrument’s applicable interest rate. The table below summarizes the Company’s interest rate swap agreements as of June 30, 2011 (dollars in thousands):

						Interest Rate
						Contractual	Fixed LIBOR
	Transaction Date	Maturity Date	Amount			Component	Interest Rate
Consolidated:	July 2010(1)	January 2014	$	50,000		LIBOR		1.474	%
Unconsolidated:	September 2008	September 2011		28,000	(2)	LIBOR		3.47	%

(1)	The interest rate swap agreement became effective on January 18, 2011.
(2)	The Company remains liable, in the event of default by the joint venture, for $7.0 million, or 25% of the total, which reflects its ownership percentage in the joint venture.

The Company’s interest rate swap agreements are designated as effective cash flow hedges and the Company records any unrealized gains associated with the change in fair value of the swap agreements within equity and “Prepaid expenses and other assets” and any unrealized losses within equity and “Accounts payable and other liabilities.” The Company records its proportionate share of unrealized gains or losses on its cash flow hedges associated with its unconsolidated joint ventures within equity and “Investment in affiliates.”

Total comprehensive income (loss) is summarized as follows (amounts in thousands):

Segment Information [Abstract]

Segment Information

(14) Segment Information

The Company’s reportable segments consist of four distinct reporting and operational segments within the greater Washington D.C, region in which it operates: Maryland, Washington, D.C., Northern Virginia and Southern Virginia. Prior to 2011, the Company had reported its properties located in Washington, D.C. within its Northern Virginia reporting segment. However, due to the Company’s growth within the Washington, D.C. region, it has altered its internal structure, which includes changing the Company’s internal decision making process regarding its Washington, D.C. properties. Therefore, the Company feels it is appropriate to separate the properties owned in Washington, D.C. into its own reporting segment.

The Company evaluates the performance of its segments based on the operating results of the properties located within each segment, which excludes large non-recurring gains and losses, gains from sale of real estate assets, interest expense, general and administrative costs, acquisition costs or any other indirect corporate expense to the segments. In addition, the segments do not have significant non-cash items other than straight-line and deferred market rent amortization reported in their operating results. There are no inter-segment sales or transfers recorded between segments.

The results of operations for the Company’s four reportable segments are as follows (dollars in thousands):

Fair Value Measurements

Fair Value Measurements [Abstract]

Fair Value Measurements

(10) Fair Value Measurements

The Company adopted accounting provisions that outline a valuation framework and create a fair value hierarchy, which distinguishes between assumptions based on market data (observable inputs) and a reporting entity’s own assumptions about market data (unobservable inputs). The new disclosures increase the consistency and comparability of fair value measurements and the related disclosures. Fair value is identified, under the standard, as the price that would be received to sell an asset or paid to transfer a liability between willing third parties at the measurement date (an exit price). In accordance with GAAP, certain assets and liabilities must be measured at fair value, and the Company provides the necessary disclosures that are required for items measured at fair value as outlined in the accounting requirements regarding fair value.

Financial assets and liabilities, as well as those non-financial assets and liabilities requiring fair value measurement, are measured using inputs from three levels of the fair value hierarchy.

The three levels are as follows:

Level 1 — Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. An active market is defined as a market in which transactions for the assets or liabilities occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 — Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active (markets with few transactions), inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.), and inputs derived principally from or corroborated by observable market data correlation or other means (market corroborated inputs).

Level 3 — Unobservable inputs, only used to the extent that observable inputs are not available, reflect the Company’s assumptions about the pricing of an asset or liability.

In accordance with accounting provisions and the fair value hierarchy described above, the following table shows the fair value of the Company’s consolidated assets and liabilities that are measured on a non-recurring and recurring basis as of June 30, 2011 and December 31, 2010 (amounts in thousands):

	Balance at
	June 30,

Recurring Measurements:

Contingent consideration related to acquisition of:
Ashburn Center		1,398		—		—		1,398

There were no assets or liabilities measured on a non-recurring basis at June 30, 2011.

Interest Rate Derivatives

On January 18, 2011, the Company fixed LIBOR at 1.474% on $50.0 million of its variable rate debt through an interest rate swap agreement that matures on January 15, 2014. The derivative is fair valued based on prevailing market yield curve on the measurement date. Also, the Company evaluates counter-party risk in calculating the fair value of the interest rate swap derivative instrument. The Company’s interest rate swap derivative is an effective cash flow hedge and any change in fair value is recorded in the Company’s equity section as “Accumulated Other Comprehensive Loss.”

The Company uses a third party to assist with the valuation of its interest rate swap agreements. The third party takes a daily “snapshot” of the market to obtain close of business rates. The snapshot includes over 7,500 rates including LIBOR fixings, Eurodollar futures, swap rates, exchange rates, treasuries, etc. This market data is obtained via direct feeds from Bloomberg and Reuters and from Inter-Dealer Brokers. The selected rates are compared to their historical values. Any rate that has changed by more than normal mean and related standard deviation would be considered an outlier and flagged for further investigation. The rates are than compiled through a valuation process that generates daily valuations, which are used to value the Company’s interest rate swap agreements.

A summary of the Company’s interest rate derivatives liability is as follows (amounts in thousands):

	Six months ended
	June 30,
	2011		2010
Balance at December 31,	$	396	$	1,741
Deconsolidation (1)		—		(396	)
Unrealized loss (gain)		392		(1,089	)
Balance at June 30,	$	788	$	256

⁽¹⁾ On January 1, 2010, the Company deconsolidated RiversPark I and all its assets and liabilities, including its interest rate derivative liability, were removed from the Company’s consolidated balance sheets.

The Company recorded an unrealized loss of $0.4 million for the six months ended June 30, 2011 and a unrealized gain of $1.1 million for the six months ended June 30, 2010, related to its derivative liability, which is included in “Accounts payable and other liabilities” in the Company’s consolidated balance sheets.

Contingent Consideration

On March 25, 2011, the Company acquired 840 First Street, NE, in Washington, D.C. for an aggregate purchase price of $90.0 million, with up to $10.0 million of additional consideration payable upon the terms of a lease renewal by the building’s sole tenant or the re-tenanting of the property. At acquisition, the Company was in active negotiations with the existing tenant to renew its lease through August 2023. As a result, the Company recorded a contingent consideration obligation of $9.4 million at acquisition. In July 2011, the building’s sole tenant renewed its lease. Based on the probability of renewal and lease terms used in the original estimate of fair value, the value of contingent consideration remained unchanged. The fair value of the contingent consideration obligation was determined based on several probability weighted discounted cash flow scenarios that projected stabilization being achieved at certain timeframes. The fair value was based, in part, on significant inputs, which are not observable in the market, thus representing a Level 3 measurement in accordance with the fair value hierarchy.

The Company has a contingent consideration obligation associated with the 2009 acquisition of Ashburn Center. As part of the acquisition price of Ashburn Center, the Company entered into a fee agreement with the seller under which the Company will be obligated to pay additional consideration upon the property achieving stabilization per specified terms of the agreement. The Company determines the fair value of the obligation through an income approach based on discounted cash flows that project stabilization being achieved within a certain timeframe. The more significant inputs associated with the fair value determination of the contingent consideration include estimates of capitalization rates, discount rates and various assumptions regarding the property’s operating performance and profitability.

The Company did not recognize any gain or loss associated with its contingent consideration for the three and six months ended June 30, 2011. During the first quarter of 2010, the Company fully leased the Ashburn Center, which resulted in an increase in its potential obligation, and recorded a $0.7 million increase in its contingent consideration to reflect the increase in the Company’s potential obligation with a corresponding entry to “Contingent Consideration Related to Acquisition of Property” in its consolidated statements of operations. The Company has classified its contingent consideration liabilities within “Accounts payable and other liabilities” and any changes in its fair value subsequent to their acquisition date valuation are charged to earnings. There was no significant change in the fair value of the contingent consideration during the quarter ended June 30, 2010.

A summary of the Company’s consolidated contingent consideration obligations is as follows (amounts in thousands):

	Six months ended
	June 30,
	2011		2010
Balance at December 31,	$	1,398	$	688
Increase in fair value		—		710
Additions to contingent consideration obligation		9,356		—
Balance at June 30,	$	10,754	$	1,398

Impairment of Real Estate Assets

The Company regularly reviews market conditions for possible impairment of a property’s carrying value. When circumstances such as adverse market conditions, changes in management’s intended holding period or potential sale to a third party indicate a possible impairment of a property, an impairment analysis is performed.

For the three months ended June 30, 2011 and 2010, the Company did not record any impairment on its real estate assets. During the first quarter of 2011 and 2010, the Company incurred impairment charges of $2.7 million and $0.6 million, respectively, for properties that were disposed of in the three months ended June 30, 2011 and 2010, respectively.

On December 29, 2010, the Company acquired 7458 Candlewood Road, which is located in the Company’s Maryland reporting segment. Due to the bankruptcy of an acquired tenant, the Company realized an impairment charge of $2.4 million to reflect the fair value of the intangible asset associated with the tenant’s lease, which was determined to have no value. The non-recoverable value of the intangible assets was based on, among other items, an analysis of current market rates, the present value of future cash flows that were discounted using capitalization rates, lease renewal probabilities, hypothetical leasing timeframes, historical leasing commissions, expected value of tenant improvements and recently executed leases.

In September 2010, the Company adjusted its anticipated holding period for its Old Courthouse Square property, which is located in the Company’s Maryland reporting segment. The Company entered into a non-binding contract to sell the asset in October 2010. As a result, the Company realized a $3.4 million impairment charge to reduce the property’s carrying value to reflect its fair value, less any potential selling costs. The property was sold on February 18, 2011 for net proceeds of $10.8 million. The Company determined the fair value of the property through an assessment of market data in working with a real estate broker on the transaction and based on the execution of a non-binding letter of intent. The fair value was further validated through an income approach based on discounted cash flows that reflected a reduced holding period.

With the exception of its contingent consideration obligation, the Company did not re-measure or complete any transactions involving non-financial assets or non-financial liabilities that are measured on a recurring basis during the six months ended June 30, 2011. Also, no transfers into and out of fair value measurements levels occurred during the six months ended June 30, 2011 or 2010.

Financial Instruments

The carrying amounts of cash equivalents, accounts and other receivables and accounts payable, with the exception of any items listed above, approximate their fair values due to their short-term maturities. The Company uses third parties with mezzanine lending expertise to value its notes receivable based on comparable deals, market analysis and underlying asset operating results. The Company calculates the fair value of its debt instruments by discounting future contractual principal and interest payments using prevailing market rates for securities with similar terms and characteristics at the balance sheet date. The carrying amount and estimated fair value of the Company’s note receivables and debt instruments at June 30, 2011 and December 31, 2010 are as follows (amounts in thousands):

	June 30, 2011				December 31, 2010

Income Taxes

(8) Income Taxes

Beginning in the fourth quarter of 2010, the Company acquired properties located in Washington D.C., which are subject to local franchise taxes. During the three and six months ended June 30, 2011, the Company recognized a benefit for income taxes of $0.1 million and $0.5 million, respectively, related to franchise taxes levied by the city of Washington D.C. at an effective rate of 9.975%. The Company acquired its first property in Washington, D.C. that was subject to franchise tax in the fourth quarter of 2010 and was not subject to any franchise taxes during the three and six months ended June 30, 2010.

The Company recognizes deferred tax assets only to the extent that it is more likely than not that deferred tax assets will be realized based on consideration of available evidence, including future reversals of existing taxable temporary differences, future projected taxable income and tax planning strategies. The Company’s deferred tax assets and liabilities are primarily associated with differences in the GAAP and tax basis of its real estate assets arising from acquisition costs, intangible assets and deferred market rent assets and liabilities that are associated with properties located in Washington D.C. and recorded in its consolidated balance sheets. As of June 30, 2011 and December 31, 2010, the Company recorded its deferred tax assets within “Prepaid expenses and other assets” and recorded its deferred tax liabilities within “Accounts payable and other liabilities” in the Company’s consolidated balance sheets.

The Company has not recorded a valuation allowance against its deferred tax assets as it determined that is more likely than not that future operations will generate sufficient taxable income to realize the deferred tax assets. The Company has not recognized any deferred tax assets or liabilities as a result of uncertain tax positions and has no material net operating loss, capital loss or alternative minimum tax carryovers. There was no (benefit) provision for income taxes associated with the Company’s discontinued operations for any period presented.

As the Company believes it both qualifies as a REIT and will not be subject to federal income tax, a reconciliation between the income tax provision calculated at the statutory federal income tax rate and the actual income tax provision has not been provided.

Description of Business

(1) Description of Business

First Potomac Realty Trust (the “Company”) is a leader in the ownership, management, development and redevelopment of office and industrial properties in the greater Washington, D.C. region. The Company separates its properties into four distinct segments, which it refers to as the Maryland, Washington, D.C., Northern Virginia and Southern Virginia reporting segments. The Company strategically focuses on acquiring and redeveloping properties that it believes can benefit from its intensive property management and seeks to reposition these properties to increase their profitability and value. The Company’s portfolio contains a mix of single-tenant and multi-tenant office and industrial properties as well as business parks. Office properties are single-story and multi-story buildings that are used primarily for office use; business parks contain buildings with office features combined with some industrial property space; and industrial properties generally are used as warehouse, distribution or manufacturing facilities.

References in these unaudited condensed consolidated financial statements to “we,” “our” or “First Potomac,” refer to the Company and its subsidiaries, on a consolidated basis, unless the context indicates otherwise.

The Company conducts its business through First Potomac Realty Investment Limited Partnership, the Company’s operating partnership (the “Operating Partnership”). The Company is the sole general partner of, and, as of June 30, 2011, owned a 95.5% interest in, the Operating Partnership. The remaining interests in the Operating Partnership, which are presented as noncontrolling interests in the Operating Partnership in the accompanying unaudited condensed consolidated financial statements, are limited partnership interests, some of which are owned by several of the Company’s executive officers and trustees who contributed properties and other assets to the Company upon its formation, and other unrelated parties.

At June 30, 2011, the Company wholly-owned or had a controlling interest in properties totaling 13.7 million square feet and had a noncontrolling ownership interest in properties totaling an additional 0.5 million square feet through four unconsolidated joint ventures. The Company also owned land that can accommodate approximately 1.6 million square feet of additional development. The Company derives substantially all of its revenue from leases of space within its properties. As of June 30, 2011, the Company’s largest tenant was the U.S. Government, which along with government contractors, accounted for over 20% of the Company’s total annualized rental revenue. The U.S Government also accounted for approximately a third of the Company’s outstanding accounts receivables at June 30, 2011. The majority of the accounts receivable related to the government was due to the clarification of terms in a specific lease, which has been resolved, and the Company expects to collect the outstanding balance on the specified lease in the third quarter. The Company operates so as to qualify as a real estate investment trust (“REIT”) for federal income tax purposes.

The majority of the development and redevelopment costs incurred through the Company’s ongoing projects have taken place at Three Flint Hill in the Company’s Northern Virginia region. Three Flint Hill is a 174,000 square foot, eight-story Class A office building. The Company has incurred approximately $9.9 million in redevelopment costs, which include architectural, and engineering design fees and permit fees as well as demolition, glass, HVAC, electrical, plumbing, and lobby finish work.

The Company anticipates the majority of the development and redevelopment efforts on these projects will continue throughout 2011 and expected to be completed in 2012.

Investment in Affiliates

(5) Investment in Affiliates

The Company owns an interest in several properties for which it does not control the activities that are most significant to the operations of the properties. As a result, the assets, liabilities and operating results of these noncontrolled properties are not consolidated within the Company’s consolidated financial statements. The Company’s investment in these properties is recorded as “Investment in affiliates” in its consolidated balance sheets.

At January 1, 2010, the Company had a 25% noncontrolling interest in the two separate joint ventures that owned RiversPark I and II. During the fourth quarter of 2010, the Company entered into two separate joint ventures, in which it had a 50% noncontrolling interest, to own 1750 H Street, NW and Aviation Business Park.

The net assets of the Company’s unconsolidated joint ventures consisted of the following (amounts in thousands):

	June 30, 2011		December 31, 2010
Assets:
Rental property, net	$	103,638	$	104,559

⁽¹⁾ Of the total mortgage debt that encumbers the Company’s unconsolidated properties, $7.0 million is recourse to the Company.

The following table summarizes the results of operations of the Company’s unconsolidated joint ventures. The Company’s share of earnings or losses related to its unconsolidated joint ventures is recorded in its consolidated statements of operations as “Equity in losses of affiliates” (amounts in thousands):

Share-Based Compensation [Abstract]

Share-Based Compensation

(13) Share-Based Compensation

The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The expense associated with the share based awards will be recognized over the period during which an employee is required to provide services in exchange for the award — the requisite service period (usually the vesting period). The fair value for all share-based payment transactions are recognized as a component of income from continuing operations.

Option Exercises

The Company received approximately $46 thousand and $7 thousand from the exercise of stock options during the three months ended June 30, 2011 and 2010, respectively, and $64 thousand and $16 thousand for the six months ended June 30, 2011 and 2010, respectively. Shares issued as a result of stock option exercises are funded through the issuance of new shares. The total intrinsic value of options exercised during the three months ended June 30, 2011 and 2010 were $25 thousand and $5 thousand, respectively, and $34 thousand and $9 thousand for the six months ended June 30, 2011 and 2010, respectively.

Non-vested share awards

On May 19, 2011, the Company issued a total of 20,310 restricted share awards to its non-employee trustees, all of which will vest on the first anniversary of the award date. The trustee shares were fair valued based on the share price of the underlying common shares on the date of issuance.

The Company recognized compensation expense associated with its restricted share awards of $0.6 million and $0.9 million for the three months ended June 30, 2011 and 2010, respectively, and $1.2 million and $1.9 million for the six months ended June 30, 2011 and 2010, respectively. Dividends on all restricted share awards are recorded as a reduction of equity. The Company applies the two-class method for determining EPS as its outstanding unvested shares with non-forfeitable dividend rights are considered participating securities. The Company’s excess of distributions over earnings related to participating securities are shown as a reduction in net income available to common shareholders in the Company’s computation of EPS.

A summary of the Company’s non-vested share awards as of June 30, 2011 is as follows:

				Weighted
	Non-vested			Average Grant
	Shares			Date Fair Value
Non-vested at March 31, 2011		782,433		$	12.70
Granted		20,310			16.25
Vested		(53,775	)		14.58
Non-vested at June 30, 2011		748,968			12.66

A summary of non-vested share awards and activity for the period ended March 31, 2011 is discussed in the Company’s first quarter 2011 Form 10-Q.

As of June 30, 2011, the Company had $4.7 million of unrecognized compensation cost related to non-vested shares. The Company anticipates this cost will be recognized over a weighted-average period of 3.3 years.

Discontinued Operations

(6) Discontinued Operations

On May 27, 2011, the Company sold its Gateway West property for net proceeds of $4.8 million, which equated to an approximate 4% capitalization rate. The property is a four-building, 111,481 square foot office park in Westminster, Maryland, which the Company acquired as part of a portfolio acquisition in 2004. During the first quarter of 2011, the Company recorded a $2.7 million impairment charge based on the difference between the contractual sales price less anticipated selling costs and the carrying value of the property.

On June 22, 2011, the Company sold Aquia Commerce Center I & II, a two building, 64,488 square foot property in Stafford, Virginia, for net proceeds of $11.3 million. The Company reported a gain on the sale of $2.0 million.

The following table is a summary of property dispositions whose operating results, along with Gateway West and Aquia Commerce Center I & II’s operating results, are reflected as discontinued operations in the Company’s condensed consolidated statements of operations:

Summary of Significant Accounting Policies [Abstract]

Summary of Significant Accounting Policies

(2) Summary of Significant Accounting Policies

(a) Principles of Consolidation

The unaudited condensed consolidated financial statements of the Company include the accounts of the Company, the Operating Partnership, the subsidiaries of the Operating Partnership in which it has a controlling interest and First Potomac Management LLC, a wholly-owned subsidiary that manages the majority of the Company’s properties. All intercompany balances and transactions have been eliminated in consolidation.

The Company has condensed or omitted certain information and footnote disclosures normally included in financial statements presented in accordance with U.S. generally accepted accounting principles (“GAAP”) in the accompanying unaudited condensed consolidated financial statements. The Company believes the disclosures made are adequate to prevent the information presented from being misleading. However, the unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2010 and as updated from time to time in other filings with the Securities and Exchange Commission.

In the Company’s opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments and accruals necessary to present fairly the Company’s financial position as of June 30, 2011, the results of its operations for the three and six months ended June 30, 2011 and 2010 and its cash flows for the six months ended June 30, 2011 and 2010. Interim results are not necessarily indicative of full-year performance due, in part, to the timing of transactions and the impact of acquisitions and dispositions throughout the year.

(b) Use of Estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires management of the Company to make a number of estimates and assumptions relating to the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Estimates include the amount of accounts receivable that may be uncollectible; recoverability of notes receivable, future cash flows, discount and capitalization rate assumptions used to fair value acquired properties and to test impairment of certain long-lived assets and goodwill; market lease rates, lease-up periods, leasing and tenant improvement costs used to fair value intangible assets acquired and probability weighted cash flow analysis used to fair value contingent liabilities. Actual results could differ from those estimates.

(c) Rental Property

Rental property is carried at initial cost less accumulated depreciation and, when appropriate, impairment losses. Improvements and replacements are capitalized at cost when they extend the useful life, increase capacity or improve the efficiency of the asset. Repairs and maintenance are charged to expense when incurred. Depreciation and amortization are recorded on a straight-line basis over the estimated useful lives of the assets. The estimated useful lives of the Company’s assets, by class, are as follows:

Buildings	39 years
Building improvements	5 to 20 years
Furniture, fixtures and equipment	5 to 15 years
Tenant improvements	Shorter of the useful lives of the assets or the terms of the related leases

The Company regularly reviews market conditions for possible impairment of a property’s carrying value. When circumstances such as adverse market conditions, changes in management’s intended holding period or potential sale to a third party indicate a possible impairment of the fair value of a property, an impairment analysis is performed. The Company assesses potential impairments based on an estimate of the future undiscounted cash flows (excluding interest charges) expected to result from the property’s use and eventual disposition. This estimate is based on projections of future revenues, expenses, capital improvement costs, expected holding periods and capitalization rates. These cash flows consider factors such as expected market trends and leasing prospects, as well as the effects of leasing demand, competition and other factors. If impairment exists due to the inability to recover the carrying value of a real estate investment based on forecasted undiscounted cash flows, an impairment loss is recorded to the extent that the carrying value exceeds the estimated fair value of the property. The Company is required to make estimates as to whether there are impairments in the carrying values of its investments in real estate. Further, the Company will record an impairment loss if it expects to dispose of a property, in the near term, at a price below carrying value. In such an event, the Company will record an impairment loss based on the difference between a property’s carrying value and its projected sales price less any estimated costs to sell.

The Company will classify a building as held-for-sale in the period in which it has made the decision to dispose of the building, the Company’s Board of Trustees or a designated delegate has approved the sale, a binding agreement to purchase the property has been signed under which the buyer has committed a significant amount of nonrefundable cash and no significant financing contingencies exist that could cause the transaction not to be completed in a timely manner. The Company will classify any impairment loss, together with the building’s operating results, as discontinued operations in its consolidated statements of operations for all periods presented and classify the assets and related liabilities as held-for-sale in its consolidated balance sheets in the period the sale criteria are met. Interest expense is reclassified to discontinued operations only to the extent the held-for-sale property is secured by specific mortgage debt and the mortgage debt will not be secured to another property owned by the Company after the disposition.

The Company recognizes the fair value, if sufficient information exists to reasonably estimate the fair value, of any liability for conditional asset retirement obligations when incurred, which is generally upon acquisition, construction, development or redevelopment and/or through the normal operation of the asset.

The Company capitalizes interest costs incurred on qualifying expenditures for real estate assets under development or redevelopment while being readied for their intended use in accordance with accounting requirements regarding capitalization of interest. The Company will capitalize interest when qualifying expenditures for the asset have been made, activities necessary to get the asset ready for its intended use are in progress and interest costs are being incurred. Capitalized interest also includes interest associated with expenditures incurred to acquire developable land while development activities are in progress and the direct compensation costs of the Company’s construction personnel who manage the development and redevelopment projects, but only to the extent the employee’s time can be allocated to a project. For the three and six months ended June 30, 2011, capitalized compensation costs were immaterial. Capitalization of interest will end when the asset is substantially complete and ready for its intended use, but no later than one year from completion of major construction activity, if the property is not occupied. Capitalized interest is depreciated over the useful life of the underlying assets, commencing when those assets are placed into service.

(d) Notes Receivable

The Company lends money to the owners of real estate properties, which are collateralized by a direct or indirect interest in the real estate property. The Company records these investments as “Notes receivable, net” in its consolidated balance sheets. The investments are recorded net of any discount or issuance costs, which are amortized over the life of the respective note receivable using the effective interest method. The Company records interest received from notes receivable and amortization of any discount or issuance costs within “Interest and other income” in its consolidated statements of operations.

In December 2010, the Company provided a $25.0 million subordinated loan to the owners of 950 F Street, NW, a 287,000 square-foot office building in Washington, D.C., which is secured by a portion of the owners’ interest in the property. The loan has a fixed interest rate of 12.5% and was initially recorded net of $0.3 million of issuance costs. The loan matures on April 1, 2017 and is repayable in full on or after December 21, 2013. For the three and six months ended June 30, 2011, the Company recorded interest income associated with the loan of $0.8 million and $1.6 million, respectively.

In April 2011, the Company provided a $30.0 million subordinated loan to the owners of America’s Square, a 461,000 square-foot office complex in Washington, D.C., which is secured by a portion of the owners’ interest in the property. The loan has a fixed interest rate of 9.0% and was initially recorded net of $0.1 million of issuance costs. The loan matures on May 1, 2016 and is repayable in full on or after October 16, 2012, subject to yield maintenance. For the three and six months ended June 30, 2011, the Company recorded interest income associated with the loan of $0.6 million.

The Company will establish a provision for anticipated credit losses associated with its notes receivables and debt investments when it anticipates that it may be unable to collect any contractually due amounts. This determination is based on upon such factors as delinquencies, loss experience, collateral quality and current economic or borrower conditions. Estimated losses are recorded as a charge to earnings to establish an allowance for credit losses that the Company estimates to be adequate based on these factors. The Company has not recorded any losses associated with its notes receivable during 2011 and 2010.

(e) Reclassifications

Certain prior year amounts have been reclassified to conform to the current year presentation.

(f) Application of New Accounting Standards

In June 2011, new accounting guidance was issued regarding the presentation of other comprehensive income that will eliminate the option of reporting other comprehensive income and its components in the Company’s Statement of Equity. The amendment provides companies the option to present components of net income and comprehensive income as either a single continuous statement or as two separate but consecutive statements. The amendment does not change what items are reported in other comprehensive income or the requirement to report reclassification of items from other comprehensive income to net income. The required disclosures are effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2011. Early adoption is permitted. The Company does not believe the implementation of these disclosures will have a material impact on its consolidated financial statements.

On July 19, 2011, the Company acquired Greenbrier Towers I & II in Chesapeake, Virginia for a contractual price of $16.7 million. The property consists of two office buildings totaling 172,000 square feet and is 86% leased to over 40 tenants. The acquisition was funded with proceeds from the sale of Aquia Commerce Center I & II and a draw on the Company’s line of credit.

On August 4, 2011, the Company formed a joint venture with Perseus Realty, LLC to acquire the Greyhound Bus Terminal site at 1005 First Street, NE for $46.8 million, of which, $38.4 million was paid at closing and the remaining $8.4 million will be paid in August 2013. The joint venture intends on developing the 1.6 acre site that can accommodate development of up to approximately 712,000 square feet of office space. The site is currently occupied by the Greyhound Bus Terminal, which will lease back the site under a ten-year lease agreement with a termination option after the second lease year. Greyhound has already announced that it intends to relocate to nearby Union Station. The Company estimates a 6.5% return from the lease-back while development is being planned. When the joint venture is fully capitalized, the Company anticipates owning 97% of the joint venture.
