PART I

ITEM 1. BUSINESS

Overview

First Potomac Realty Trust (the “Company”) is a self-managed, self-administered Maryland real estate investment trust. The Company focuses on owning, developing, redeveloping and operating industrial properties and business parks in the Washington, D.C. metropolitan area and other major markets in Maryland and Virginia, which it refers to as the Southern Mid-Atlantic region. The Company separates its properties into three distinct segments, which it refers to as the Maryland, Northern Virginia and Southern Virginia regions. The Company has elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”).

References in this Annual Report on Form 10-K to “we,” “our” or “First Potomac,” refer to First Potomac Realty Trust and its subsidiaries, on a consolidated basis, unless the context indicates otherwise.

The Company was formed in July 2003 to be the successor general partner of First Potomac Realty Investment Limited Partnership, the Company’s operating partnership (the “Operating Partnership”). The Company owns all of its properties and conducts its business through the Operating Partnership. As of December 31, 2007, the Company was the sole general partner of, and owned a 96.8% interest in, the Operating Partnership. The remaining interests in the Operating Partnership consist of limited partnership interests owned by third parties, including some of the Company’s executive officers and trustees who contributed properties and other assets to the Company upon its formation.

The Company strategically focuses on acquiring, developing 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 of properties contains a mix of single-tenant and multi-tenant industrial properties and business parks. Industrial properties generally are used as warehouse, distribution or manufacturing facilities, while business parks combine office building features with industrial property space. As of December 31, 2007, the Company owned approximately 11.4 million square feet, and the Company’s properties were 86.3% occupied by 610 tenants. The Company also owned land that can accommodate approximately 1.6 million square feet of development. As of December 31, 2007, the Company’s largest tenant was the U.S. Government, which accounted for 7.3% of the Company’s total annualized rental revenue. The Company derives substantially all of its revenue from leases of space within its properties.

Narrative Description of Business

The Operating Partnership was formed in 1997 to utilize management’s knowledge of and experience in the Southern Mid-Atlantic real estate market to seek to create the leading industrial property and business park owner in the region. The Company believes that the large number of properties meeting its investment criteria and the fragmented ownership of industrial properties and business parks in the region create an opportunity for it to achieve this goal. According to data from CoStar Group, a real estate market research firm, at December 31, 2007, First Potomac was the largest owner of industrial properties and business parks in the Washington, D.C. metropolitan area with a 2.8% share of the market.

The Company’s acquisition strategies focus on industrial properties and business parks in its target markets that generally meet the following investment criteria:

	§		established locations;

	§		below-market rents; and/or

	§		absentee ownership.

The Company also targets properties that it believes can be converted, in whole or in part, to a higher use. With business parks in particular, the Company has found that, over time, the property can be improved by converting space that is primarily warehouse space into space that contains more office use. Because office rents are generally higher than warehouse rents, the Company has been able to add revenue and value by converting space as market demand allows.

The Company uses its contacts, relationships and local market knowledge to identify and opportunistically acquire industrial properties and business parks in its target markets. The Company also believes that its reputation for professional property management allows it to attract high-quality tenants to the properties that it acquires, enabling the Company to increase the properties’ profitability and value.

Significant 2007 Developments

During 2007, the Company completed the following:

	•		Acquired six properties totaling approximately 0.9 million square feet at a total cost of $88.6 million;

	•		Completed developments totaling 253,000 square feet at 15395 John Marshall Highway, Crossways Commerce Center and Cavalier Industrial Park at a total cost of approximately $18.6 million, of which 134,500 square feet was pre-leased prior to completion;

	•		Entered into an amendment to its unsecured revolving credit facility, which extended the facility’s maturity by one year to April 26, 2010, with the ability to further extend the facility to April 26, 2011 and lowered the interest rate spread from 120 to 160 basis points over the London Interbank Offered Rate (“LIBOR”) to 80 to 135 basis points over LIBOR;

	•		Filed a shelf registration statement with the Securities and Exchange Commission that permits the Company to offer and sell common shares, preferred shares and debt securities from time to time on a continuous basis under Rule 415 of the Securities Act of 1933, as amended;

	•		Entered into a $50.0 million Secured Term Loan with Key Bank, N.A. The loan, which matures in August 2010, has a one-year extension option and can be expanded to $100 million; and

	•		Purchased, from unaffiliated limited partners, 180,580 Operating Partnership units in its Operating Partnership for $5.2 million in cash.

Total assets at December 31, 2007 were $1.1 billion compared to $1.0 billion at December 31, 2006.

Competitive Advantages

The Company believes that its business strategy and operating model distinguish it from other owners, operators and acquirers of real estate in a number of ways, which include:

	•		Experienced Management Team. The Company’s executive officers average more than 20 years of real estate experience in the Washington, D.C. metropolitan area.

	•		Focused Strategy. The Company is the only publicly traded REIT focused on industrial properties and business parks in the Southern Mid-Atlantic region, one of the largest, most stable markets for assets of this type.

	•		Value-Added Management Approach. Through the Company’s hands-on approach to management, leasing, renovation and repositioning, the Company endeavors to add significant value to the properties that it acquires from absentee institutional landlords and smaller, less sophisticated owners by improving tenant quality and increasing occupancy rates and net rent per square foot.

	•		Strong Market Dynamics. The Company’s target markets exhibit stable rental rates, frequent acquisition opportunities, and strong tenant bases, according to Delta Associates, a market research firm.

The Company’s Market

Ownership of industrial properties and business parks in the Southern Mid-Atlantic region is highly fragmented. Delta Associates, a real estate market research firm, reported that, as of December 31, 2007, the Washington-Baltimore region contained approximately 334 million square feet of industrial properties and business parks, which the Company estimates has an aggregate fair market value of more than $50 billion based on its knowledge of comparable per square foot sale prices of these property classes in this region. According to CoStar Group, a real estate market research firm, these properties are owned by hundreds of different owners, ranging from large institutional investors to small investors and owner/occupants, with no single owner holding a significant share of the property market. For example, as of December 31, 2007, in the Washington, D.C. metropolitan area, First Potomac was the largest owner of industrial properties and business parks with 2.8% of the market by square footage.

The Washington, D.C. metropolitan area has the largest economy of the Company’s target markets. In addition to its size, the Washington, D.C. metropolitan area also boasts one of the most stable economies in the country, primarily attributable to the presence of the U.S. Government and the private contractors that service the U.S. Government. The private sector is supported by the procurement spending of the U.S. Government, which has enhanced the area’s technology industry and tempered the negative impact of national economic cycles. As of December 31, 2007, the Washington, D.C. area was the country’s eighth largest metropolitan area in population, ranked seventh for job growth and was the fourth largest job base behind only New York, Los Angeles and Chicago according to the U.S. Department of Labor. As of December 31, 2007, the Washington metropolitan area was fourth in economic output according to the U.S. Conference of Mayors.

The Company’s other primary markets are Norfolk, Virginia, Baltimore, Maryland and Richmond, Virginia. Norfolk is home to the largest military station in the world, according to the United States Navy, and has an even larger percentage of federal government employees than Washington, D.C. In addition, the Norfolk port is the second busiest port, in terms of container volume, on the East Coast of the United States. The Baltimore metropolitan area, with approximately 205 million square feet of industrial space has recently strengthened its position as a major trade and distribution center with strong employment growth in wholesale and retail trade. Richmond, the capital of Virginia, maintains a market demand for smaller to mid-size tenants.

Increases in U.S. Government spending since 2001, including increased military and defense spending by the Department of Defense and the Department of Homeland Security, has benefited the industrial property and business park markets in the Southern Mid-Atlantic region. The Company believes that additional government spending, both defense and non-defense related, will continue to create further demand for industrial properties and business parks in its markets.

Competition

We compete with other REITs, other public and private real estate companies, private real estate investors and lenders in acquiring properties. Many of these entities have greater resources than we do or other competitive advantages. We also face competition in leasing or subleasing available properties to prospective tenants.

Environmental Matters

Under various federal, state and local environmental laws and regulations, a current or previous owner, operator or tenant of real estate property may be required to investigate and clean up hazardous or toxic substances or petroleum product releases or threats of releases at such property, and may be held liable to a government entity or to third parties for property damage and for investigation, clean up and monitoring costs incurred by such parties in connection with the actual or threatened contamination. Such laws typically impose clean up responsibility and liability without regard to fault, or whether or not the owner, operator or tenant knew of or caused the presence of the contamination. The liability under such laws may be joint and several for the full amount of the investigation, clean-up and monitoring costs incurred or to be incurred or actions to be undertaken. These costs may be substantial, and can exceed the value of the property. The presence of contamination or the failure to properly remediate contamination on such property may adversely affect the ability of the owner, operator or tenant to sell or rent such property or to borrow using such property as collateral, and may adversely impact our investment in a property.

Federal regulations require building owners and those exercising control over a building’s management to identify and warn, via signs and labels, of potential hazards posed by workplace exposure to installed asbestos-containing materials and potentially asbestos-containing materials in their building. The regulations also set forth employee training, record keeping and due diligence requirements pertaining to asbestos-containing materials and potentially asbestos-containing materials. Significant fines can be assessed for violation of these regulations. Building owners and those exercising control over a building’s management may be subject to an increased risk of personal injury lawsuits by workers and others exposed to asbestos-containing materials and potentially asbestos-containing materials as a result of the regulations. Federal, state and local laws and regulations also govern the removal, encapsulation, disturbance, handling and/or disposal of asbestos-containing materials. Such laws may impose liability for improper handling or a release to the environment of asbestos-containing materials.

Prior to closing any property acquisition, if appropriate, the Company obtains such environmental assessments as may be prudent in order to attempt to identify potential environmental concerns at such properties. These assessments are carried out in accordance with an appropriate level of due diligence and generally may include a physical site inspection, a review of relevant federal, state and local environmental and health agency database records, one or more interviews with appropriate site-related personnel, review of the property’s chain of title and review of historic aerial photographs. The Company may also conduct limited subsurface investigations and test for substances of concern where the results of the first phase of the environmental assessments or other information, indicates possible contamination or where the Company’s consultants recommend such procedures.

The Company believes that its properties are in compliance in all material respects with all federal and state regulations regarding hazardous or toxic substances and other environmental matters. The Company has not been notified by any governmental authority of any material non-compliance, liability or claim relating to hazardous or toxic substances or other environmental matter in connection with any of its properties.

In 1991, it was discovered that portions of the soil and groundwater under the Newington Business Park Center in Lorton, Virginia (the “Site”) had been affected by one or more leaking underground storage tanks from an adjacent property owned by a third-party and operated by Waste Management of Virginia, Inc. The Virginia Department of Environmental Quality (the “DEQ”), ordered the third-party owner to clean up the petroleum-based free product (gasoline range petroleum hydrocarbons) on the adjacent property and the Site. A treatment system was designed to capture and monitor the contamination from both the adjacent property and the Site. The case was closed by the DEQ after risk-based levels of contamination were contained, but re-opened when free petroleum product was again found on top of the groundwater under the Site. The third-party owner paid for further removal of free petroleum product directly from two groundwater wells at the Site. In August 2005, the DEQ requested that three additional monitoring wells be installed on the Site because free petroleum product continued to be present in two of the monitoring wells. The three new monitoring wells were installed by Waste Management of Virginia, Inc. and sampling revealed no free petroleum product in those wells. However, free petroleum product was observed in 2006 in the two older wells. As a result of the presence of free petroleum product, Waste Management of Virginia, Inc. submitted a Corrective Action Plan to the DEQ, which was approved. The plan required periodic free product recovery from the impacted wells and annual groundwater quality sampling and analysis of four down gradient wells. A total of four consecutive events exhibiting no observable free product and a final groundwater sampling event were required for closure by DEQ. These criteria were met with four quarterly product gauging and recoveries ending in August 2007 and the annual groundwater sampling of the same date. On November 19, 2007, DEQ issued a letter closing the case.

Employees

The Company had 131 employees as of March 1, 2008. The Company believes relations with its employees are good.

ITEM 1A. RISK FACTORS

An investment in our Company involves various risks, including the risk that you might lose your entire investment. The following discussion concerns some of the risks associated with our business. These risks are interrelated, and you should treat them as a whole. The risks described below are not the only risks that may affect us. Additional risks and uncertainties not presently known to us or not identified below, may also materially and adversely affect our business, financial condition, results of operations and ability to make distributions to our security holders.

Risks Related to Our Business and Properties

Our business strategy contemplates expansion through acquisition and we may not be able to adapt our management and operational systems to successfully integrate new properties into our portfolio without unanticipated disruption or expense.

Our business strategy contemplates expansion through acquisition. As we increase the size of our portfolio, we cannot assure you that we will be able to adapt our management, administrative, accounting and operational systems, or hire and retain sufficient operational staff to integrate new properties into our portfolio or manage any future acquisitions of properties without operating disruptions or unanticipated costs. Our acquisitions of properties will generate additional operating expenses that we will be required to pay. Our past growth has required, and our growth will continue to require, increased investment in management personnel, professional fees, other personnel, financial and management systems and controls and facilities, which could cause our operating margins to decline from historical levels, especially in the absence of revenue growth. As we acquire additional properties, we will be subject to risks associated with managing new properties, including tenant retention and mortgage default. Our failure to successfully integrate acquisitions into our portfolio and manage our growth could have a material adverse effect on our results of operations and financial condition.

We are subject to the credit risk of our tenants, which may fail to make lease payments and thereby cause a significant decrease in our revenues.

We are subject to the credit risk of our tenants. We cannot assure you that our tenants will not default on their leases and fail to make rental payments to us. In particular, local economic conditions and factors affecting the industries in which our tenants operate may affect our tenants’ ability to make lease payments to us. Moreover, we may be unable to locate a replacement tenant in a timely manner or on comparable or better terms if a tenant defaults on its lease. The loss of rental revenues from a number of our tenants and our inability to replace such tenants may adversely affect our profitability and our ability to meet our financial obligations.

A majority of our tenants hold leases covering less than 10,000 square feet. Many of these tenants are small companies with nominal net worth. The loss of rental revenues from a number of our tenants may adversely affect our profitability and our ability to meet our financial obligations.

Loss of the U.S. Government as a tenant could lead to a substantial decrease in our cash flow and an impairment of the value of our properties.

The U.S. Government accounted for 7.3% of our total annualized rental revenue as of December 31, 2007. On July 31, 2003, the United States Department of Defense issued the Unified Facilities Criteria (the “UFC”), which establish minimum antiterrorism standards for the design and construction of new and existing buildings leased by the departments and agencies of the Department of Defense. The loss of the federal government as a tenant resulting from our inability to comply with the UFC standards or for any other reason or the loss of a future significant tenant would have an adverse effect on our financial results and the value of our affected properties. A reduction or elimination of rent from the U.S. Government or other significant tenants would reduce our cash flow and adversely affect our ability to make distributions to our security holders.

Our debt level may have a negative impact on our ability to make distributions to our security holders and pursue our business plan.

We have incurred indebtedness in connection with the acquisition of our properties, and we will incur new indebtedness in the future in connection with our acquisition, development and operating activities.

Our use of debt financing creates risks, including risks that:

	•		our cash flow will be insufficient to make required payments of principal and interest;

	•		we will be unable to refinance some or all of our indebtedness or that any refinancing will not be on terms as favorable as those of the existing indebtedness;

	•		required debt payments will not be reduced if the economic performance of any property declines;

	•		debt service obligations will reduce funds available for distribution to our security holders and funds available for acquisitions;

	•		most of our secured debt obligations require the lender to be made whole to the extent we decide to pay off the debt prior to the maturity date; and

	•		any default on our indebtedness could result in acceleration of those obligations and possible loss of property to foreclosure.

If the economic performance of any of our properties declines, our ability to make debt service payments would be adversely affected. If a property is mortgaged to secure payment of indebtedness and we are unable to meet mortgage payments, we may lose that property to lender foreclosure with a resulting loss of income and asset value.

We do not have a policy limiting the amount of debt that we may incur, although we have established 55% to 65% as the target range for our total debt to market capitalization. However, under the covenants of our unsecured revolving credit facility and senior notes, we have certain restrictions on the amount of debt we are allowed to incur. Our leverage levels may make it difficult to obtain additional financing based on our current portfolio or to refinance existing debt on favorable terms or at all. Failure to obtain additional financing could impede our ability to grow and develop our business. Our leverage levels also may adversely affect the market price of our securities if an investment in our Company is perceived to be more risky than an investment in our peers.

If we do not have adequate cash to fund our business, we will be adversely affected.

Our business requires access to adequate cash to finance our operations, distributions, capital expenditures, debt service obligations, development costs and property acquisition costs, if any. We expect to generate the cash to be used for these purposes primarily with operating cash flow, borrowings under our unsecured revolving credit facility and secured term loan, and the proceeds from sales of strategically identified assets and potential joint ventures. We may not be able to generate sufficient cash for our operations, particularly if we are unable to renew leases, lease vacant space or re-lease space as leases expire according to expectations. Moreover, since July 2007, the real estate debt markets entered a period of uncertainty, which may reduce our access to funding alternatives, or our ability to refinance debt on favorable terms, or at all. Market conditions may also hinder our ability to complete joint venture transactions and sales of strategically identified assets.

Our variable rate debt subjects us to interest rate risk.

We have an unsecured revolving credit facility that bears interest at a variable rate on any amounts drawn on the facility and a $50.0 million secured term note that bears interest at a variable rate. In January 2008, we entered into a $50 million interest rate swap to hedge the interest rate exposure on our one month LIBOR based borrowings. The interest rate swap is an effective hedge that fixes the underlying interest rate on a $50 million notional balance at 2.71% plus a spread of 0.70% to 1.25% (depending on our overall leverage level), for a total rate ranging from 3.41% to 3.96%. We may incur additional variable rate debt in the future. Increases in interest rates on variable rate debt would increase our interest expense, which would adversely affect net earnings and cash available for payment of our debt obligations and distributions to our security holders.

We have and may continue to engage in hedging transactions, which can limit our gains and increase exposure to losses.

We have and may continue to enter into hedging transactions to attempt to protect us from the effects of interest rate fluctuations on floating rate debt, or in some cases, prior to a proposed debt issuance. Our hedging transactions may include entering into interest rate swap agreements or interest rate cap or floor agreements, or other interest rate exchange contracts. Hedging activities may not have the desired beneficial impact on our results of operations or financial condition. No hedging activity can completely insulate us from the risks associated with changes in interest rates. Moreover, interest rate hedging could fail to protect us or adversely affect us because, among other things:

•

available interest rate hedging may not correspond directly with the interest rate risk for which we seek 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;

•

the credit quality of the party owing money on the hedge may be downgraded to such an extent that it impairs our ability to sell or assign our side of the hedging transaction; and

•

the value of derivatives used for hedging may be adjusted from time to time in accordance with accounting rules to reflect changes in fair value. Downward adjustments, or “mark-to-market losses,” would reduce our shareholders’ equity.

Hedging involves risk and typically involves costs, including transaction costs, that may reduce our overall returns on our investments. These costs increase as the period covered by the hedging increases and during periods of rising and volatile interest rates. These costs will also limit the amount of cash available for distribution to shareholders. We generally intend to hedge as much of the interest rate risk as management determines is in our best interests given the cost of such hedging transactions. The REIT qualification rules may limit our ability to enter into hedging transactions by requiring us to limit our income from hedges. If we are unable to hedge effectively because of the REIT rules, we will face greater interest rate exposure.

We compete with other parties for tenants and property acquisitions and many of these parties have substantially greater resources than we have.

Our business strategy contemplates expansion through acquisition. The commercial real estate industry is highly competitive, and we compete with substantially larger companies, including substantially larger REITs and institutional investment funds, for the acquisition, development and leasing of properties. Some of these companies are national or regional operators with far greater resources than we have. As a result, we may not be able or have the opportunity to make suitable investments on favorable terms in the future. Competition in a particular area also could adversely affect our ability to lease our properties or to increase or maintain rental rates.

Newly developed and acquired properties may not produce the cash flow that we expect, which could adversely affect our overall financial performance.

Over the last few years, we have focused our efforts on the acquisition, development and redevelopment of industrial properties and business parks. We intend to continue to acquire and develop industrial and business park properties. In deciding whether to acquire or develop a particular property, we make assumptions regarding the expected future performance of that property. In particular, we estimate the return on our investment based on expected occupancy and rental rates. If our estimated return on investment proves to be inaccurate and the property is unable to achieve the expected occupancy and rental rates, it may fail to perform as we expected in analyzing our investment. When we acquire a property, we often plan to reposition or redevelop that property with the goal of increasing profitability. Our estimate of the costs of repositioning or redeveloping an acquired property may prove to be inaccurate, which may result in our failure to meet our profitability goals. Additionally, we have acquired properties not fully leased, and the cash flow from existing operations may be insufficient to pay the operating expenses and debt service associated with that property until the property is more fully leased. If one or more of these new properties do not perform as expected or we are unable to successfully integrate new properties into our existing operations, our financial performance may be adversely affected.

All of our properties are located in the Southern Mid-Atlantic region, making us vulnerable to changes in economic conditions in that region.

Economic conditions in the Southern Mid-Atlantic region may significantly affect the occupancy and rental rates of our properties. A decline in occupancy and rental rates, in turn, may significantly affect our profitability and our ability to satisfy our financial obligations. The economic condition of the region may depend on one or more industries and, therefore, an economic downturn in one of these industry sectors may adversely affect our performance. Local real estate market conditions may include a large supply of competing space, and we compete for tenants based on rental rates, attractiveness and location of a property, and quality of maintenance and management services. As a result of the geographic concentration of our properties, our performance, our ability to make cash distributions, and the value of our properties will depend upon economic conditions in the region, including local real estate conditions and competition. There can be no assurance that these markets will continue to grow or that economic conditions will remain favorable. If unfavorable economic conditions occur in the region, our ability to make distributions to our security holders could be adversely affected. In particular, we are directly affected by decreases in federal government spending.

Development and construction risks could adversely affect our profitability.

Our renovation, redevelopment, development and related construction activities may subject us to the following risks:

	§		we may be unable to obtain, or suffer delays in obtaining, necessary zoning, land-use, building, occupancy and other required governmental permits and authorizations, which could result in increased costs or our abandonment of these projects;

	§		we may incur construction costs for a property which exceed our original estimates due to increased costs for materials or labor or other costs that we did not anticipate;

	§		we may not be able to obtain financing on favorable terms, which may render us unable to proceed with our development activities; and

	§		we may be unable to complete construction and lease-up of a property on schedule, which could result in increased debt service expense or construction costs.

Additionally, the time frame required for development, construction and lease-up of these properties means that we may have to wait years for a significant cash return. Because we are required to make cash distributions to our shareholders, if the cash flow from operations or refinancing is not sufficient, we may be forced to borrow additional money to fund such distributions.

Failure to succeed in new markets may limit our growth.

We may make selected acquisitions outside our current geographic market from time to time as appropriate opportunities arise. Our historical experience is in the Southern Mid-Atlantic region, and we may not be able to operate successfully in other market areas. We may be exposed to a variety of risks if we choose to enter new markets. These risks include:

	§		a lack of market knowledge and understanding of the local economies;

	§		an inability to identify promising acquisition or development opportunities;

	§		an inability to employ construction trades people; and

a lack of familiarity with local government and permitting procedures.

Any of these factors could adversely affect the profitability of projects outside our current markets and limit the success of our acquisition and development strategy. If our acquisition and development strategy is negatively affected, the profitability, growth, and development of our business may be impeded.

We may be unable to renew expiring leases or re-lease vacant space on a timely basis or on attractive terms, which could significantly decrease our cash flow.

Current tenants may not renew their leases upon the expiration of their terms. Alternatively, current tenants may attempt to terminate their leases prior to the expiration of their current terms. If non-renewals or terminations occur, we may not be able to locate qualified replacement tenants and, as a result, we could lose a significant source of revenue while remaining responsible for the payment of our obligations. Moreover, the terms of a renewal or new lease may be less favorable than the current lease terms. Any of these factors could cause a decline in lease revenue, which would have a negative impact on our profitability.

Under some of our leases, tenants have the right to terminate prior to the scheduled expiration of the lease.

Some of our leases for our current properties provide tenants with the right to terminate prior to the scheduled expiration of the lease. If a tenant terminates its lease with us prior to the expiration of the term, we may be unable to re-lease that space on as favorable terms, or at all, which could adversely affect our cash flow and our ability to make distributions to our security holders.

Property owned through joint ventures, or in limited liability companies and partnerships in which we are not the sole equity holder, may limit our ability to act exclusively in our interests.

We may make investments through partnerships, limited liability companies or joint ventures in the future. Partnership, limited liability company or joint venture investments may involve various risks, including the following:

	§		our partners, co-members or joint ventures might become bankrupt (in which event we and any other remaining general partners or joint ventures would generally remain liable for the liabilities of the partnership or joint venture);

	§		our partners, co-members or joint ventures might at any time have economic or other business interests or goals that are inconsistent with our business interests or goals;

	§		our partners, co-members or joint ventures may be in a position to take action contrary to our instructions, requests, policies, or objectives, including our current policy with respect to maintaining our qualification as a real estate investment trust; and

	§		agreements governing joint ventures, limited liability companies and partnerships often contain restrictions on the transfer of a joint venture’s, member’s or partner’s interest or “buy-sell” or other provisions that may result in a purchase or sale of the interest at a disadvantageous time or on disadvantageous terms.

Our organizational documents do not limit the amount of available funds that we may invest in partnerships, limited liability companies or joint ventures. The occurrence of one or more of the events described above could adversely affect our financial condition, results of operations, cash flow and ability to make distributions with respect to, and the market price of, our securities.

Risks Related to Our Organization and Structure

Our executive officers have agreements that provide them with benefits in the event of a change in control of our Company or if their employment agreement is terminated without cause or not renewed.

We have entered into employment agreements with our executive officers, Douglas J. Donatelli, Nicholas R. Smith, Barry H. Bass, James H. Dawson and Joel F. Bonder that provide them with severance benefits if their employment ends under certain circumstances following a change in control of our Company, terminated without cause, or if the executive officer resigns for “good reason” as defined in the employment agreements. These benefits could increase the cost to a potential acquirer of our Company and thereby prevent or deter a change in control of the Company that might involve a premium price for our securities or otherwise be in the interests of our security holders.

We may experience conflicts of interest with several members of our board of trustees and our executive officers relating to their ownership of units of our Operating Partnership.

Some of our trustees and executive officers may have conflicting duties because, in their capacities as our trustees and executive officers, they have a duty to our Company, and in our capacity as general partner of our Operating Partnership, they have a fiduciary duty to the limited partners, and some of them are themselves limited partners. These conflicts of interest could lead to decisions that are not in your best interest. Conflicts may arise when the interests of our shareholders and the limited partners of our Operating Partnership diverge, particularly in circumstances in which there may be an adverse tax consequence to the limited partners, such as upon the sale of assets or the repayment of indebtedness.

We depend on key personnel with long-standing business relationships, the loss of whom could threaten our ability to operate our business successfully.

Our future success depends, to a significant extent, upon the continued services of our senior management team, including Douglas J. Donatelli. In particular, the extent and nature of the relationships that Mr. Donatelli has developed in the real estate community in our markets is critically important to the success of our business. Although we have an employment agreement with Mr. Donatelli and other key executive officers, there is no guarantee that Mr. Donatelli will remain employed with us. We do not maintain key person life insurance on any of our officers. The loss of services of one or more members of our senior management team, particularly Mr. Donatelli, would harm our business and prospects. Further, loss of a member of our senior management team could be negatively perceived in the capital markets, which could have an adverse effect on the market price of our securities.

Certain of our trustees may have conflicts of interest with our Company.

One of our Company’s trustees, Louis T. Donatelli is also Chairman of Donatelli Development, Inc. (formerly Donatelli & Klein, Inc), a real estate development and investment firm that focuses on the Washington, D.C. market. Mr. Donatelli continues to provide services to Donatelli Development, Inc. In addition, Mr. Donatelli may own industrial properties or business parks outside of the Company’s specific geographic area of operation.

One of our Company’s trustees, Terry L. Stevens, currently serves as Senior Vice President and Chief Financial Officer of Highwoods Properties, Inc., a fully integrated, North Carolina-based REIT that owns, leases, manages, develops and constructs office and retail properties, some of which are located in our target markets. As a result, conflicts may arise when the Company and Highwoods Properties, Inc. compete in the same markets for properties, tenants, personnel and other services.

Our rights and the rights of our security holders to take action against our trustees and officers are limited, which could limit your recourse in the event of actions not in your best interests.

Maryland law provides that a trustee has no liability in that capacity if he or she performs his or her duties in good faith, in a manner he or she reasonably believes to be in our best interests and with the care that an ordinarily prudent person in a like position would use under similar circumstances. Our amended and restated declaration of trust authorizes us to indemnify our trustees and officers for actions taken by them in those capacities to the extent permitted by Maryland law. In addition, our declaration of trust limits the liability of our trustees and officers for money damages, except for liability resulting from:

	§		actual receipt of an improper benefit or profit in money, property or services; or

	§		a final judgment based upon a finding of active and deliberate dishonesty by the trustee or officer that was material to the cause of action adjudicated.

As a result, we and our security holders may have more limited rights against our trustees and officers than might otherwise exist. Our amended and restated bylaws require us to indemnify each trustee or officer who has been successful, on the merits or otherwise, in the defense of any proceeding to which he or she is made a party by reason of his or her service to us. In addition, we may be obligated to fund the defense costs incurred by our trustees and officers.

Our board of trustees may approve the issuance of preferred shares with terms that may discourage a third party from acquiring us.

Our declaration of trust permits our board of trustees to issue up to 50,000,000 preferred shares, issuable in one or more classes or series. Our board of trustees may increase the number of preferred shares authorized by our declaration of trust without shareholder approval. Our board of trustees may also classify or reclassify any unissued preferred shares and establish the preferences and rights (including the right to vote, to participate in earnings and to convert into securities) of any such preferred shares, which rights may be superior to those of our common shares. Thus, our board of trustees could authorize the issuance of preferred shares with terms and conditions that could have the effect of discouraging a takeover or other transaction in which holders of some or a majority of the common shares might receive a premium for their shares over the then current market price of our common shares.

Our ownership limitations may restrict business combination opportunities.

To qualify as a REIT under the Internal Revenue Code, no more than 50% of the value of our outstanding shares of beneficial interest may be owned, directly or under applicable attribution rules, by five or fewer individuals (as defined to include certain entities) during the last half of each taxable year (other than our first REIT taxable year). To preserve our REIT qualification, our declaration of trust generally prohibits direct or indirect ownership by any person of (i) more than 8.75% of the number or value of our outstanding common shares or (ii) more than 8.75% of the value of our outstanding shares of all classes. Generally, shares owned by affiliated owners will be aggregated for purposes of the ownership limitation. Our declaration of trust has created a special higher ownership limitation of no more than 14.9% for the group comprised of Louis T. Donatelli, Douglas J. Donatelli and certain related persons. Unless the applicable ownership limitation is waived by our board of trustees prior to transfer, any transfer of our common shares that would violate the ownership limitation will be null and void, and the intended transferee will acquire no rights in such shares. Common shares that would otherwise be held in violation of the ownership limit will be designated as “shares-in-trust” and transferred automatically to a trust effective on the day before the purported transfer or other event giving rise to such excess ownership. The beneficiary of the trust will be one or more charitable organizations named by us. The ownership limitation could have the effect of delaying, deterring or preventing a change in control or other transaction in which holders of common shares might receive a premium for their common shares over the then current market price or that such holders might believe to be otherwise in their best interests. The ownership limitation provisions also may make our common shares an unsuitable investment vehicle for any person seeking to obtain, either alone or with others as a group, ownership of (i) more than 8.75% of the number or value of our outstanding common shares or (ii) more than 8.75% in value of our outstanding shares of all classes.

Our board of trustees may change our investment and operational policies and practices without a vote of our security holders, which limits your control of our policies and practices.

Our major policies, including our policies and practices with respect to investments, financing, growth, debt capitalization, REIT qualification and distributions, are determined by our board of trustees. Although we have no present intention to do so, our board of trustees may amend or revise these and other policies from time to time without a vote of our security holders. Accordingly, our security holders have limited control over changes in our policies.

Our declaration of trust and bylaws do not limit the amount of indebtedness that we or our Operating Partnership may incur. If we become highly leveraged, then the resulting increase in debt service could adversely affect our ability to make payments on our outstanding indebtedness and harm our financial condition.

Our declaration of trust contains provisions that make removal of our trustees difficult, which could make it difficult for our shareholders to effect changes to our management.

Our declaration of trust provides that a trustee may only be removed upon the affirmative vote of holders of a majority of our outstanding common shares. Vacancies may be filled by the board of trustees. This requirement makes it more difficult to change our management by removing and replacing trustees.

Our bylaws may only be amended by our board of trustees, which could limit your control of certain aspects of our corporate governance.

Our board of trustees has the sole authority to amend our bylaws. Thus, the board is able to amend the bylaws in a way that may be detrimental to your interests.

Maryland law may discourage a third party from acquiring us.

Maryland law provides broad discretion to our board of trustees with respect to its fiduciary duties in considering a change in control of our Company, including that our board is subject to no greater level of scrutiny in considering a change in control transaction than with respect to any other act by our board.

The Maryland Business Combination Act restricts mergers and other business combinations between our Company and an interested shareholder. An “interested shareholder” is defined as any person who is the beneficial owner of 10% or more of the voting power of our common shares and also includes any of our affiliates or associates that, at any time within the two year period prior to the date of a proposed merger or other business combination, was the beneficial owner of 10% or more of our voting power. Additionally, the “control shares” provisions of the Maryland General Corporation Law, or MGCL, are applicable to us as if we were a corporation. These provisions eliminate the voting rights of shares acquired in quantities so as to constitute “control shares,” as defined under the MGCL. Our amended and restated declaration of trust and/or bylaws, provide that we are not bound by the Maryland Business Combination Act or the control share acquisition statute. However, in the case of the control share acquisition statute, our board of trustees may opt to make this statute applicable to us at any time, and may do so on a retroactive basis.

Finally, the “unsolicited takeovers” provisions of the MGCL permit our board of trustees, without shareholder approval and regardless of what is currently provided in our declaration of trust or bylaws, to implement takeover defenses that we do not yet have. These provisions may have the effect of inhibiting a third party from making an acquisition proposal for our Company or of delaying, deferring or preventing a change in control of our Company under circumstances that otherwise could provide the holders of our common shares with the opportunity to realize a premium over the then current market price or would otherwise be in the interests of our shareholders.

Risks Related to the Real Estate Industry

Real estate investments are inherently risky, which could adversely affect our profitability and our ability to make distributions to our security holders.

Real estate investments are subject to varying degrees of risk. If we acquire or develop properties and they do not generate sufficient operating cash flow to meet operating expenses, including debt service, capital expenditures and tenant improvements, our income and ability to make distributions to our security holders will be adversely affected. Income from properties may be adversely affected by:

	§		decreases in rent and/or occupancy rates due to competition or other factors;

	§		increases in operating costs such as real estate taxes, insurance premiums, site maintenance and utilities;

	§		changes in interest rates and the availability of financing; and

	§		changes in laws and governmental regulations, including those governing real estate usage, zoning and taxes.

General economic conditions may adversely affect our financial condition and results of operations.

Periods of economic slowdown or recession in the United States and in other countries, rising interest rates or declining demand for real estate, or the public perception that any of these events may occur, could result in a general decline in rents or an increased incidence of defaults by our tenants under existing leases, which could adversely affect our financial position, results of operations, cash flow, trading price of our securities and our ability to satisfy our debt service obligations and to make distributions to our security holders.

Illiquidity of real estate investments could significantly impede our ability to respond to adverse changes in the performance of our properties and harm our financial condition.

Because real estate investments are relatively illiquid, our ability to promptly sell one or more properties in our portfolio in response to adverse changes in the performance of such properties may be limited, thus harming our financial condition. The real estate market is affected by many factors that are beyond our control, including:

	§		adverse changes in national and local economic and market conditions;

	§		changes in interest rates and in the availability, cost and terms of debt financing;

	§		changes in governmental laws and regulations, fiscal policies and zoning ordinances and costs of compliance with laws and regulations, fiscal policies and ordinances;

	§		the ongoing need for capital improvements, particularly in older buildings;

	§		changes in operating expenses; and

	§		civil unrest, acts of war and natural disasters, including earthquakes and floods, which may result in uninsured and underinsured losses.

We cannot predict whether we will be able to sell any property for the price or on the terms set by us, or whether any price or other terms offered by a prospective purchaser would be acceptable to us. We also cannot predict the length of time needed to find a willing purchaser and to close the sale of a property.

We may be required to expend funds to correct defects or to make improvements before a property can be sold. We cannot assure you that we will have funds available to correct those defects or to make those improvements. In acquiring a property, we may agree to lock-out provisions that materially restrict us from selling that property for a period of time or impose other restrictions, such as a limitation on the amount of debt that can be placed or repaid on that property. We may also acquire properties that are subject to a mortgage loan that may limit our ability to sell the properties prior to the loan’s maturity. These factors and any others that would impede our ability to respond to adverse changes in the performance of our properties could have a material adverse effect on our operating results and financial condition, as well as our ability to make distributions to our security holders.

The costs of compliance with or liabilities under environmental laws may harm our operating results.

Our operating expenses could be higher than anticipated due to the cost of complying with, or liability created under, existing or future environmental laws and regulations. An owner of real property can face liability for environmental contamination created by the presence or discharge of hazardous substances, including petroleum-based products, on, under or from the property. Similarly, a former owner of real property can face liability for the disposal of hazardous substances that occurred during the time of ownership. We may face liability regardless of:

	§		our knowledge of the contamination;

	§		the extent of the contamination;

	§		the timing of the release of the contamination;

	§		the cause of the contamination; or

	§		the party responsible for the contamination of the property.

Environmental liability may include the following, without limitation: investigation and feasibility study costs, remediation costs, litigation costs, oversight costs, monitoring costs, institutional control costs, penalties from state and federal agencies, and claims brought by citizen suits. Moreover, operations on-site may be required to be suspended until certain environmental contamination is remediated and/or permits are received. This may result in a default of the terms of the lease entered into with our tenants.

There may be environmental problems associated with our properties of which we are unaware. For example, some of our properties contain, or may have contained in the past, underground tanks for the storage of hazardous substances, petroleum-based or waste products, or some of our properties may have been used historically to conduct industrial operations, and any of these circumstances could create a potential for release of hazardous substances. If environmental contamination exists on our properties, we could become subject to strict, joint and several liability for the contamination by virtue of our ownership interest.

The presence of hazardous substances on, under or from a property may adversely affect our ability to sell the property and we may incur substantial remediation costs, thus harming our financial condition. In addition, although our leases generally require our tenants to operate in compliance with all applicable laws and to indemnify us against any environmental liabilities arising from a tenant’s activities on the property, we could nonetheless be subject to strict liability by virtue of our ownership interest for environmental liabilities created by our tenants, and we cannot be sure that our tenants would satisfy their indemnification obligations under the applicable sales agreement or lease. The discovery of material environmental liabilities attached to our properties could have a material adverse effect on our results of operations and financial condition and our ability to make distributions to our security holders.

The Company’s properties may contain or develop harmful mold, which could lead to liability for adverse health effects and costs of remediating the problem.

When excessive moisture accumulates in buildings or on building materials, mold growth may occur, particularly if the moisture problem remains undiscovered or is not addressed over a period of time. Some molds may produce airborne toxins or irritants. Concern about indoor exposure to mold has been increasing as exposure to mold may cause a variety of adverse health effects and symptoms, including allergic or other reactions. As a result, the presence of significant mold at any of our properties could require us to undertake a costly remediation program to contain or remove the mold from the affected property. In addition, the presence of significant mold could expose us to liability from our tenants, employees of our tenants and others if property damage or health concerns arise.

Compliance with the Americans with Disabilities Act and fire, safety and other regulations may require us to make unintended expenditures that adversely impact our ability to make distributions to our security holders.

All of our properties are required to comply with the Americans with Disabilities Act, or the ADA. The ADA has separate compliance requirements for “public accommodations” and “commercial facilities,” but generally requires that buildings be made accessible to people with disabilities. Compliance with the ADA requirements could require removal of access barriers and non-compliance could result in the imposition of fines by the U.S. Government or an award of damages to private litigants, or both. While the tenants to whom we lease properties are obligated by law to comply with the ADA provisions, and typically under our leases are obligated to cover costs associated with compliance, if required changes involve greater expenditures than anticipated, or if the changes must be made on a more accelerated basis than anticipated, the ability of these tenants to cover costs could be adversely affected and we could be required to expend our own funds to comply with the provisions of the ADA, which could adversely affect our results of operations and financial condition and our ability to make distributions to security holders. In addition, we are required to operate our properties in compliance with fire and safety regulations, building codes and other land use regulations, as they may be adopted by governmental agencies and bodies and become applicable to our properties. We may be required to make substantial capital expenditures to comply with those requirements and these expenditures could have a material adverse effect on our ability to make distributions to our security holders.

An uninsured loss or a loss that exceeds the policies on our properties could subject us to lost capital or revenue on those properties.

Under the terms and conditions of the leases currently in force on our properties, our tenants generally are required to indemnify and hold us harmless from liabilities resulting from injury to persons, air, water, land or property, on or off the premises, due to activities conducted on the properties, except for claims arising from the negligence or intentional misconduct of us or our agents. Additionally, tenants are generally required, at the tenant’s expense, to obtain and keep in full force during the term of the lease, liability and full replacement value property damage insurance policies. Our largest tenant, the federal government, is not required to maintain property insurance at all. We have obtained comprehensive liability, casualty, flood and rental loss insurance policies on our properties. All of these policies may involve substantial deductibles and certain exclusions. In addition, we cannot assure you that our tenants will properly maintain their insurance policies or have the ability to pay the deductibles. Should a loss occur that is uninsured or in an amount exceeding the combined aggregate limits for the policies noted above, or in the event of a loss that is subject to a substantial deductible under an insurance policy, we could lose all or part of our capital invested in, and anticipated revenue from, one or more of the properties, which could have a material adverse effect on our operating results and financial condition, as well as our ability to make distributions to our security holders.

Terrorist attacks and other acts of violence or war may affect any market on which our securities trade, the markets in which we operate, our operations and our profitability.

Terrorist attacks may negatively affect our operations. These attacks or armed conflicts may directly impact the value of our properties through damage, destruction, loss or increased security costs. The terrorism insurance that we obtain may not be sufficient to cover loss for damages to our properties as a result of terrorist attacks. In addition, certain losses resulting from these types of events are uninsurable and others would not be covered by our current terrorism insurance. Additional terrorism insurance may not be available at a reasonable price or at all. If the properties in which we invest are unable to obtain sufficient and affordable insurance coverage, the value of those investments could decline, and in the event of an uninsured loss, we could lose all or a portion of an investment.

The United States may enter into armed conflicts in the future. The consequences of any armed conflicts are unpredictable, and we may not be able to foresee events that could have an adverse effect on our business.

Any of these events could result in increased volatility in or damage to the United States and worldwide financial markets and economy. They also could result in a continuation of the current economic uncertainty in the United States or abroad. Adverse economic conditions could affect the ability of our tenants to pay rent, which could have a material adverse effect on our operating results and financial condition, as well as our ability to make distributions to our security holders, and may result in volatility in the market price for our securities.

Tax Risks of our Business and Structure

If we fail to remain qualified as a REIT for federal income tax purposes, we will not be able to deduct our distributions, and our income will be subject to taxation.

We elected to be taxed as a REIT under the Internal Revenue Code commencing with our short taxable year ended December 31, 2003, which affords us significant tax advantages. The requirements for qualification as a REIT, however, are complex and our management has limited experience in operating a REIT. If we fail to meet these requirements and do not qualify for certain relief provisions, our distributions to our shareholders will not be deductible by us and we will be subject to a corporate level tax on our taxable income. This would substantially reduce our cash available to make distributions to our shareholders. In addition, incurring corporate income tax liability might cause us to borrow funds, liquidate some of our investments or take other steps that could negatively affect our operating results. Moreover, if our REIT status is terminated because of our failure to meet a REIT qualification requirement or if we voluntarily revoke our election, unless relief provisions applicable to certain REIT qualification failures apply, we would be disqualified from electing treatment as a REIT for the four taxable years following the year in which REIT status is lost.

Distribution requirements relating to qualification as a REIT for federal income tax purposes limit our flexibility in executing our business plan.

Our business plan contemplates growth through acquisitions. To maintain our status as a REIT for federal income tax purposes, we generally are required to distribute to our shareholders at least 90% of our REIT taxable income each year. REIT taxable income is determined without regard to the deduction for dividends paid and by excluding net capital gains. We are also required to pay tax at regular corporate rates to the extent that we distribute less than 100% of our taxable income (including net capital gains) each year. In addition, we are required to pay a 4% nondeductible excise tax on the amount, if any, by which certain distributions we pay with respect to any calendar year are less than the sum of 85% of our ordinary income for that calendar year, 95% of our capital gain net income for the calendar year and any amount of our income that was not distributed in prior years.

We have distributed, and intend to continue to distribute, to our shareholders all or substantially all of our taxable REIT income each year in order to comply with the distribution requirements of the Internal Revenue Code and to avoid federal income tax and the 4% nondeductible excise tax. Our distribution requirements limit our ability to fund acquisitions and capital expenditures through retained earnings. Thus, our ability to grow through acquisitions will be limited if we are unable to obtain debt or equity financing. In addition, differences in timing between the receipt of income and the payment of expenses in arriving at REIT taxable income and the effect of required debt amortization payments could require us to borrow funds to meet the distribution requirements that are necessary to achieve the tax benefits associated with qualifying as a REIT.

Moreover, even if we maintain our status as a REIT, any net income of a taxable REIT subsidiaries owned by our Operating Partnership would be subject to federal, state and local income taxes at regular corporate rates.

Our disposal of properties may have negative implications, including unfavorable tax consequences.

If we make a sale of a property directly or through an entity that is treated as a partnership or a disregarded entity, for federal income tax purposes, and it is deemed to be a sale of dealer property or inventory, the sale may be deemed to be a “prohibited transaction” under federal tax laws applicable to REITs, in which case our gain, or our share of the gain, from the sale would be subject to a 100% penalty tax. If we believe that a sale of a property might be treated as a prohibited transaction, we may dispose of that property through a taxable REIT subsidiary, in which case the gain from the sale would be subject to corporate income tax but not the 100% prohibited transaction tax. We cannot assure you, however, that the Internal Revenue Service will not assert successfully that sales of properties that we make directly or through an entity that is treated as a partnership or a disregarded entity, for federal income tax purposes, rather than through a taxable REIT subsidiary, are sales of dealer property or inventory, in which case the 100% penalty tax would apply.

We may be subject to adverse legislative or regulatory tax changes that could reduce the market price of our securities.

At any time, the federal income tax laws governing REITs or the administrative interpretations of those laws may be amended. Any of those new laws or interpretations may take effect retroactively and could adversely affect us or the market price of our securities.

If we or our predecessor entity failed to qualify as an S corporation for any of our tax years prior to our initial public offering, we may fail to qualify as a REIT.

To qualify as a REIT, we may not have at the close of any year undistributed “earnings and profits” accumulated in any non-REIT year, including undistributed “earnings and profits” accumulated in any non-REIT year for which we or our predecessor, First Potomac Realty Investment Trust, Inc., did not qualify as an S corporation. Although we believe that we and our predecessor corporation qualified as an S corporation for federal income tax purposes for all tax years prior to our initial public offering, if it is determined that we did not so qualify, we will not qualify as a REIT. Any such failure to qualify may also prevent us from qualifying as a REIT for any of the following four tax years.

If First Potomac Management, Inc. failed to qualify as an S corporation during any of its tax years, we may be responsible for any entity level taxes due.

We believe First Potomac Management, Inc. qualified as an S corporation for federal and state income tax purposes from the time of its incorporation in 1997 through the date it merged into our Company in 2006. However, the Company may be responsible for any entity-level taxes imposed on First Potomac Management, Inc. if it did not qualify as an S corporation at any time prior to the merger. First Potomac Management, Inc.’s former shareholders have severally indemnified us against any such loss; however, in the event one or more of its former shareholders is unable to fulfill its indemnification obligation, we may not be reimbursed for a portion of the taxes.

Risks Related to an Investment in Our Common Shares

Our common shares trade in a limited market which could hinder your ability to sell our common shares.

Our equity market capitalization places us at the low end of market capitalization among all REITs. Our common shares experience relatively, limited trading volume; many investors may not be interested in owning our common shares because of the inability to acquire or sell a substantial block of our common shares at one time. This illiquidity could have an adverse effect on the market price of our common shares. In addition, a shareholder may not be able to borrow funds using our common shares as collateral because lenders may be unwilling to accept the pledge of common shares having a limited market. Any substantial sale of our common shares could have a material adverse effect on the market price of our common shares.

The market price and trading volume of our common shares may be volatile.

The market price of our common shares may become highly volatile and be subject to wide fluctuations. In addition, the trading volume in our common shares may fluctuate and cause significant price variations to occur. Some of the factors that could negatively affect our share price or result in fluctuations in the price or trading volume of our common shares include:

	§		actual or anticipated declines in our quarterly operating results or distributions;

	§		reductions in our funds from operations;

	§		increases in market interest rates that lead purchasers of our securities to demand a higher dividend yield;

	§		changes in market valuations of similar companies;

	§		adverse market reaction to any increased indebtedness we incur in the future;

	§		additions or departures of key management personnel;

	§		actions by institutional shareholders;

	§		speculation in the press or investment community; and

	§		general market and economic conditions.

The vesting of equity based compensation awards upon achievement of certain performance measures may result in unanticipated charges that could impact our operating results.

Broad market fluctuations could negatively impact the market price of our common shares.

In addition, the stock market has experienced extreme price and volume fluctuations that have affected the market price of many companies that have been unrelated to these companies’ operating performances. These broad market fluctuations could reduce the market price of our common shares. Furthermore, our operating results and prospects may be below the expectations of investors or may be lower than those of companies with comparable market capitalizations, which could lead to a material decline in the market price of our common shares.

An increase in market interest rates may have an adverse effect on the market price of our common shares.

One of the factors that investors may consider in deciding whether to buy or sell our common shares is our distribution rate as a percentage of our share price, relative to market interest rates. If market interest rates increase, prospective investors may desire a higher distribution rate on our common shares or seek securities paying higher dividends or interest. The market price of our common shares likely will be based primarily on the earnings that we derive from rental income with respect to our properties and our related distributions to shareholders, and not from the underlying appraised value of the properties themselves. As a result, interest rate fluctuations and capital market conditions can affect the market price of our common shares. For instance, if interest rates rise without an increase in our distribution rate, the market price of our common shares could decrease because potential investors may require a higher yield on our common shares as market rates on interest-bearing securities, such as bonds, rise. In addition, rising interest rates would result in increased interest expense on our non-hedged variable rate debt, thereby adversely affecting cash flow and our ability to service our indebtedness and make distributions to our shareholders.

Shares eligible for future sale may have adverse effects on our share price.

The Company cannot predict the effect, if any, of future sales of common shares, or the availability of shares for future sales, on the market price of our common shares. Sales of substantial amounts of common shares, including up to approximately 5.1 million common shares issuable upon (i) the redemption of units of our Operating Partnership, (ii) exercise of options, and (iii) the conversion of our Operating Partnership’s 4% exchangeable senior notes, or the perception that these sales could occur, may adversely affect prevailing market prices for our common shares and impede our ability to raise capital.

The Company also may issue from time to time additional common shares or preferred shares or units of our Operating Partnership in connection with the acquisition of properties, and we may grant demand or piggyback registration rights in connection with these issuances. Sales of substantial amounts of securities or the perception that these sales could occur may adversely affect the prevailing market price for our securities. In addition, the sale of these shares could impair our ability to raise capital through a sale of additional equity securities.

ITEM 7.		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 financial statements and notes thereto appearing elsewhere in this Annual Report on Form 10-K. The discussion and analysis is derived from the consolidated operating results and activities of First Potomac Realty Trust.

Overview

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 be driven by its ability to:

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

	•		sell assets to third parties or contribute properties to a joint venture; and

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

Significant 2007 Developments

During 2007, the Company completed the following:

	•		Acquired six properties totaling approximately 0.9 million square feet at a total cost of $88.6 million;

	•		Completed developments totaling 253,000 square feet at 15395 John Marshall Highway, Crossways Commerce Center and Cavalier Industrial Park at a total cost of approximately $18.6 million, of which 134,500 square feet was pre-leased prior to substantial completion;

	•		Entered into a first amendment to its unsecured revolving credit facility, which extended the facility’s maturity by one year to April 26, 2010, with the ability to further extend the facility to April 26, 2011 and lowered the interest rate spread from 120 to 160 basis points over LIBOR to 80 to 135 basis points over LIBOR;

	•		Filed a shelf registration statement with the SEC that permits the Company to offer and sell common shares, preferred shares and debt securities from time to time on a continuous basis under Rule 415 of the Securities Act of 1933, as amended;

	•		Entered into a $50.0 million Secured Term Loan with Key Bank, N.A. The loan, which matures in August 2010, has a one-year extension option and can be expanded to $100 million; and

	•		Purchased, from unaffiliated limited partners, 180,580 Operating Partnership units in its Operating Partnership for $5.2 million in cash.

Total assets at December 31, 2007 were $1.1 billion compared to $1.0 billion at December 31, 2006.

Development and Redevelopment Activity

During 2007, the Company had commenced development and redevelopment of several parcels of land, including land adjacent to previously acquired properties and land acquired with the intent to develop. The Company intends to construct business parks and/or industrial properties on a build-to-suit basis or with the intent to lease upon completion of construction.

During 2007, the Company substantially completed development work on the following properties noted below:

	•		John Marshall Highway — a 112,000 square foot flex warehouse building addition was completed on April 1, 2007. The total cost of the building was approximately $8.3 million. Development costs incurred include architectural design, site and building engineering, site work and construction activities. The building was 100% pre-leased to the existing tenant at this property;

	•		Crossways Commerce Center — a 45,000 square foot two-story office building addition was substantially completed in November 2007 at a total cost of $4.9 million. Development costs incurred include civil, architectural, structural, mechanical, electrical and plumbing design drawings as well as construction costs that included site work, concrete, steel, masonry, roofing, glass and glazing and fire protection. The Company pre-leased approximately 22,000 square feet of this addition while in development; and

	•		Cavalier Industrial Park — a 96,000 square foot warehouse building was substantially completed in December 2007 at a total cost of $5.4 million. Development costs incurred include civil, architectural, structural, mechanical, electrical and plumbing design as well as construction costs that include site work, concrete, steel masonry, roofing storefront, painting, mechanical, fire protection, plumbing and electrical.

As of December 31, 2007, the Company had incurred development and redevelopment expenditures for several buildings, of which the more significant projects are noted below:

	•		Sterling Park Business Center — a 58,000 square foot business park has been designed. The Company began development efforts on approximately 25% of the total developable land at the site. Civil site planning and storm water management for two buildings has been completed, and development costs incurred to date include overall master and site planning, geotechnical and wetland studies, civil, storm water management, architectural, structural, mechanical, electrical and plumbing engineering design. Construction costs include site concrete work for one building. Additional development costs are being incurred on several access roads required for the overall project acceptance and completion;

	•		Ammendale Business Park — a 76,000 square foot business park redevelopment. Costs incurred to date include architectural and engineering schematic development as well as construction costs that include roofing and mechanical demolition; and

	•		Enterprise Parkway — an 85,000 square foot multi-tenanted office space redevelopment. Costs incurred to date include building, lobby and common corridor renovation as well as schematic architectural and engineering design.

During 2007, the Company also began redevelopment efforts on space totaling 72,000 square feet at Gateway 270, Sterling Park Business Center and Gateway Centre. The Company will commence redevelopment efforts on unfinished vacant space through the investment of capital in electrical, plumbing and other capital improvements in order to expedite the leasing of unfinished space. The Company anticipates development and redevelopment efforts on these projects will be completed in 2008. At December 31, 2007, the Company had several land parcels that can accommodate approximately 1.6 million square feet of additional development. The Company also has a 4,500 square foot retail pad site under development and scheduled to be completed in 2008 at Snowden Center in Columbia, Maryland.

Critical Accounting Policies and Estimates

The Company’s 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 the Company’s 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 and stock-based compensation.

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

Revenue Recognition

Rental revenue under leases with scheduled rent increases or rent abatements is recognized using the straight-line method over the term of the leases. Accrued straight-line rents included in the Company’s consolidated balance sheets represent the aggregate excess of rental revenue recognized on a straight-line basis over contractual rent under applicable lease provisions. The Company’s leases generally contain provisions under which the tenants reimburse the Company for a portion of the Company’s property operating expenses and real estate taxes. Such reimbursements are recognized in the period that the expenses are incurred. Lease termination fees are recognized on the date of termination when the related leases are canceled and the Company has no continuing obligation to provide services to such former tenants.

The Company must make estimates of the collectability of its accounts receivable related to minimum rent, deferred rent, tenant reimbursements, lease termination fees and other income. The Company specifically analyzes accounts 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 recorded at cost. Improvements and replacements are capitalized when they extend the useful life, increase capacity, or improve the efficiency of the asset. Repairs and maintenance are charged to expense as incurred.

Depreciation and amortization are recorded on a straight-line basis over the estimated useful lives as follows:


Buildings		39 years
Building improvements		5 to 15 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 reviews market conditions for possible impairment of a property’s carrying value. When circumstances such as adverse market conditions or changes in management’s intended holding period indicate a possible impairment of the value of a property, an impairment analysis is performed. The Company assesses the recoverability based on an estimate of the future undiscounted cash flows (excluding interest charges) expected to result from the real estate investment’s use and eventual disposition. This estimate is based on projections of future revenues, expenses and capital improvement costs. These cash flows consider factors such as expected future operating income, trends and 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, 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 subjective assessments as to whether there are impairments in the values of its investments in real estate.

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 which could cause the transaction not to be completed in a timely manner. If these criteria are met, the Company will record an impairment loss if the fair value of the building, less anticipated selling costs, is lower than its carrying amount. The Company will classify any impairment loss, together with the building’s operating results, as discontinued operations on its statement of operations and classify the assets and related liabilities as held-for-sale on the balance sheet. Interest expense is reclassified to discontinued operations only to the extent the property to be disposed of secures specific mortgage debt.

During May 2006, the Company sold its property located at 6600 Business Parkway in Elkridge, Maryland. As a result, operating results and the gain on disposal for these assets are reflected as discontinued operations in the Company’s consolidated statements of operations. The Company has had and will have no continuing involvement with the property subsequent to its disposal.

Purchase Accounting

Acquisitions of rental property from third parties are accounted for at fair value, which 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 the fair value. The purchase price is also allocated as follows:

	§		the value of leases based on the leasing origination costs at the date of the acquisition, which approximates the market value of the lease origination costs had the in-place leases been originated on the date of acquisition; the value of in-place leases represents absorption costs for the estimated lease-up period in which vacancy and foregone revenue are incurred;

	§		the value of above and below market in-place lease values 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 lease and the estimated fair market lease rates for the corresponding spaces over the remaining non-cancelable terms of the related leases, which range from one to twenty years; and

	§		the intangible value of tenant or customer relationships.

The Company’s determination of these 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, depreciation expense and amortization expense it recognizes for these leases and associated intangible assets and liabilities.

Stock Compensation

Effective January 1, 2006, the Company adopted the fair value recognition provisions of SFAS No. 123R, Share-Based Payment, which require that the cost for all share-based payment transactions be recognized as a component of income from continuing operations. The statement requires a public entity to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award (with limited exceptions). That cost will be recognized over the period during which an employee is required to provide service in exchange for the award — the requisite service period (usually the vesting period).

Results of Operations

Comparison of the Years Ended December 31, 2007, 2006 and 2005

The Company completed acquisitions totaling $551.3 million during the three years ended December 31, 2007 and owned 11.4 million, 10.4 million and 8.3 million square feet of leasing space at December 31, 2007, 2006 and 2005, respectively. Operating results period over period are significantly affected by the volume and timing of acquisitions.

Total Revenues

Total revenues are summarized as follows:


	Years Ended December 31,						Percent			Years Ended December 31,						Percent
(amounts in thousands)	2007		2006		Increase		Change			2006		2005		Increase		Change
Rental	$	103,224	$	87,534	$	15,690		18	%	$	87,534	$	64,322	$	23,212		36	%

Rental Revenue

Rental revenue is comprised of contractual rent, the impacts of straight-line revenue and the amortization of above and below market leases. Rental revenue increased $15.7 million in 2007 as compared to 2006 primarily due to a full year of ownership of the 2006 Acquisitions, which contributed $8.8 million in additional rental revenue to the portfolio in 2007 compared to 2006. Also, the 2007 Acquisitions contributed rental revenue of $6.4 million during 2007. The remaining increase in rental revenue can be attributed to an increase in rental rates, as the average rental rates on new and renewal leases increased 16.9% and 10.3%, respectively, during 2007, as a result of 2.0 million square feet of new and renewal leases executed during the year. The increase in rental revenue in 2007 compared to 2006 includes $5.2 million for the Company’s Maryland reporting segment, $1.4 million for the Northern Virginia reporting segment and $9.1 million for the Southern Virginia reporting segment.

The Company’s portfolio occupancy was 86.3% at December 31, 2007 compared to 87.5% at December 31, 2006. The Company experienced 2.3 million square feet of expired or terminated leases during 2007. The Company’s weighted average occupancy during 2007 was 87.4% compared to 88.1% in 2006. During the fourth quarter of 2007, vacancy increased as Interstate Plaza became fully vacant as the tenant that fully occupied the building did not renew its lease. The Company also had an early termination at Diamond Hill Distribution Center, which allowed it to recapture certain space for marketing that was known to be expiring.

Rental revenue increased $23.2 million in 2006 as compared to 2005, primarily due to recognizing a full year of operations for the 2005 Acquisitions, which contributed $12.3 million in additional rental revenue to the portfolio in 2006 compared to 2005. Also, the 2006 Acquisitions generated rental revenue of $10.1 million during 2006. The Remaining Portfolio contributed to the additional increase in rental revenue as a result of increased occupancy at several properties and higher rental rates. During 2006, average rental rates on new and renewal leases increased 19.3% and 6.7%, respectively, over existing leases. The increase in rental revenue in 2006 compared to 2005 includes $3.4 million for the Company’s Maryland reporting segment, $6.1 million for the Northern Virginia reporting segment and $13.7 million for the Southern Virginia reporting segment.

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 incidental other revenues such as lease termination fees and late fees. Tenant reimbursements and other revenues increased $4.2 million in 2007 compared to 2006, primarily due to a full year of ownership of the 2006 Acquisitions, which resulted in $2.2 million of additional tenant reimbursements and other revenues to the portfolio in 2007. The 2007 Acquisitions further contributed tenant reimbursements and other revenues of $0.9 million during 2007. Tenant reimbursements and other revenues increased $1.1 million for the Remaining Portfolio during 2007 as a result of an increase in termination fee income and expense recoveries. The increase in tenant reimbursements and other revenues in 2007 compared to 2006 include $1.8 million for the Maryland reporting segment, $0.4 million for the Northern Virginia reporting segment and $2.0 million for the Southern Virginia reporting segment.

Tenant reimbursements and other revenues increased $4.7 million from 2006 to 2005, primarily due to the recognition of a full year of operations for the 2005 Acquisitions, which resulted in $2.8 million of additional tenant reimbursements and other revenues during 2006. The increase can also be attributed to the 2006 Acquisitions, which contributed $1.8 million in tenant reimbursements and other revenues during 2006. The increase in tenant reimbursements and other revenues in 2006 compared to 2005 include $0.5 million for the Company’s Maryland reporting segment, $1.3 million for the Northern Virginia reporting segment and $2.9 million for the Southern Virginia reporting segment.

Total Expenses

Property Operating Expenses

Property operating expenses are summarized as follows:


	Years Ended December 31,						Percent			Years Ended December 31,						Percent
(amounts in thousands)	2007		2006		Increase		Change			2006		2005		Increase		Change
Property operating expenses	$	26,335	$	20,338	$	5,997		29	%	$	20,338	$	13,817	$	6,521		47	%
Real estate taxes and insurance	$	11,206	$	9,026	$	2,180		24	%	$	9,026	$	6,440	$	2,586		40	%

Property Operating Expenses

Property operating expenses increased $6.0 million in 2007 as compared to 2006 primarily due to a full year of ownership of the 2006 Acquisitions, which resulted in $2.4 million of additional property operating expenses in 2007. The 2007 Acquisitions also contributed $1.6 million of property operating expenses during 2007. The balance of the increase in property operating expenses can be largely attributed to an increase in utilities expense, administrative expense and additional snow and ice removal costs from the Remaining Portfolio during 2007. Administrative expenses increased in 2007 due largely to the Company fully implementing its regional structure resulting in additional personnel and administrative costs of the three regions allocated to properties and generally recoverable from tenants. The increase in property operating expenses in 2007 compared to 2006 includes $1.8 million for the Maryland reporting segment, $0.7 million for the Northern Virginia reporting segment and $3.5 million for the Southern Virginia reporting segment.

Property operating expenses increased $6.5 million from 2006 to 2005 primarily due to recognizing a full year of operating expenses for the 2005 Acquisitions and the partial-year impact of the 2006 Acquisitions, which contributed $3.5 million and $2.0 million, respectively, in additional property operating expenses during 2006. A portion of the increase in overall property operating expenses was driven in part by increased utility costs on the Remaining Portfolio in 2006 as compared to 2005, primarily due to higher electrical rates and usage. The impact of deregulation of utilities for our Maryland properties in particular also resulted in higher competitive utility costs in 2006 as compared to 2005. In 2006, the Company entered into utility contracts that provide for fixed utility rates, thus minimizing future rate fluctuation impacts for our Maryland properties. The increase in property operating expenses in 2006 compared to 2005 includes $1.1 million for the Maryland reporting segment, $1.5 million for the Northern Virginia reporting segment and $3.9 million for the Southern Virginia reporting segment.

Real Estate Taxes and Insurance

Real estate taxes and insurance expenses increased $2.2 million from 2007 to 2006 primarily due to acquisitions. The 2006 Acquisitions and 2007 Acquisitions resulted in $1.1 million and $0.6 million, respectively, of additional real estate taxes and insurance expenses to the portfolio in 2007. The balance of the increase can be attributed to generally higher real estate taxes on the Remaining Portfolio, primarily due to higher assessments in Fairfax County, Virginia. The increase in real estate taxes and insurance expenses in 2007 compared to 2006 include $0.7 million for the Maryland reporting segment, $0.6 million for the Northern Virginia reporting segment and $0.9 million for the Southern Virginia reporting segment.

Real estate taxes and insurance expenses increased $2.6 million during 2006 as compared to 2005, is due primarily to $1.4 million in additional real estate taxes and insurance costs from a full year of ownership of the 2005 Acquisitions. The remaining increase is largely attributable to the 2006 Acquisitions, which incurred $1.2 million of real estate taxes and insurance costs during 2006. The increase in real estate taxes and insurance expenses in 2006 compared to 2005 include $0.4 million for the Maryland reporting segment, $0.7 million for the Northern Virginia reporting segment and $1.5 million for the Southern Virginia reporting segment.

Other Operating Expenses

General and administrative expenses are summarized as follows:


	Years Ended December 31,						Percent			Years Ended December 31,						Percent
(amounts in thousands)	2007		2006		Increase		Change			2006		2005		Increase		Change
	$	10,453	$	9,832	$	621		6	%	$	9,832	$	7,940	$	1,892		24	%

General and administrative expenses increased $0.6 million during 2007 compared to the same period in 2006, primarily due to increased personnel, resulting in higher compensation and benefits-related expenses. The increase in general and administrative expenses was partially offset by a reduction in incentive compensation for the Company’s executive officers.

General and administrative expenses increased $1.9 million in 2006 from 2005, primarily due to share-based compensation expense, which was accelerated due to the vesting of a portion of restricted shares awarded in 2005, as certain market based performance measures were achieved in 2006. The adoption of SFAS No. 123R, Share-Based Payment, in 2006, resulted in an increase in expense associated with stock options as well as increased expense from non-vested share awards due to the issuance of additional restricted share awards in 2006 and expense recognition using a derived service period and fair value for awards based on market conditions rather than a stated time-based vesting period of the award. As a result, share-based compensation expense increased $1.3 million in 2006 as compared to 2005. The balance of the difference resulted primarily from higher rent expense and increased personnel costs in 2006 as compared to 2005.

Depreciation and amortization expenses are summarized as follows:


	Years Ended December 31,						Percent			Years Ended December 31,						Percent
(amounts in thousands)	2007		2006		Increase		Change			2006		2005		Increase		Change
	$	41,121	$	34,536	$	6,585		19	%	$	34,536	$	24,751	$	9,785		40	%

Depreciation and amortization expense includes depreciation of real estate assets, amortization of intangible assets and leasing commissions. Depreciation and amortization expense increased $6.6 million in 2007 compared to 2006 primarily due to the 2006 and 2007 Acquisitions, which generated additional depreciation and amortization expense of $4.8 million and $3.5 million, respectively. The increase in depreciation expense from the 2007 and 2006 Acquisition was partially offset by a decline in depreciation expense from the Remaining Portfolio during 2007 as certain acquired intangible assets fully amortized.

Depreciation and amortization expense increased $9.8 million in 2006 from 2005 primarily due to depreciation and amortization expense from the 2006 and 2005 Acquisitions, which generated additional expense of $6.0 million and $5.8 million, respectively. This was offset by lower depreciation expense of $2.2 million for the Remaining Portfolio due to lower depreciation costs as a result of certain acquired intangible assets fully amortized.

Other Expenses

Interest expense is summarized as follows:


	Years Ended December 31,						Percent			Years Ended December 31,						Percent
(amounts in thousands)	2007		2006		Increase		Change			2006		2005		Increase		Change
	$	35,587	$	28,500	$	7,087		25	%	$	28,500	$	20,191	$	8,309		41	%

Interest expense increased $7.1 million during 2007 compared to the same period in 2006 due to the issuance of additional debt during 2006 to fund acquisitions and development. During December 2006, the Company completed an offering of $125.0 million of Exchangeable Senior Notes, which were issued at a discount. The issuance resulted in an additional $5.2 million of interest expense in 2007. In June 2006, the Company issued $75.0 million of unsecured Senior Notes, which resulted in $2.3 million of additional interest expense in 2007. In August 2007, the Company entered into a $50.0 million secured term loan, which resulted in interest expense of $1.3 million in 2007. Mortgage interest expense increased $1.2 million during 2007 compared to 2006, primarily due to additional mortgage debt assumed with the 2006 Acquisitions. The increase in interest expense was partially offset by a $1.2 million decrease in interest expense associated with a lower average balance on the Company’s unsecured revolving credit facility and a $1.0 million decrease associated with a term loan that was paid off in 2006. Also, the increase in interest expense was partially offset by $1.0 million of additional capitalized interest related to development and redevelopment activity in 2007.

Interest expense increased $8.3 million from 2006 from 2005, primarily due to the issuance of additional debt in 2006 to fund acquisitions and development. During 2006, the Company completed a private placement of unsecured Senior Notes totaling $75.0 million to fund the purchase of several of the 2006 Acquisitions and repay outstanding debt. Also, the Company issued $125.0 million of Exchangeable Senior Notes for net proceeds of $122.2 million, net of discount. The outstanding balances on the two notes resulted in additional interest expense of $2.8 million in 2006. The Company issued a term loan in 2006, which resulted in an additional $1.0 million of interest expense. Further, interest expense increased $2.4 million and $0.7 million as a result of the mortgage debt assumed with the 2005 and 2006 Acquisitions, respectively. The increase in interest expense can also be attributed to higher average borrowings and higher average interest rates on the Company’s unsecured revolving credit facility, as proceeds from the facility were used to fund the 2006 Acquisitions. Weighted average borrowings on the unsecured revolving credit facility increased $13.9 million and the weighted average interest rate increased 1.5 percentage points, which resulted in $1.5 million of additional interest expense in 2006. The Company had no outstanding borrowings under the credit facility as of December 31, 2006. The increase in interest expense was partially offset by the capitalization of $0.3 million of interest related to development activity in 2006. The Company did not capitalize any interest in 2005.

Interest and other income are summarized as follows:


	Years Ended December 31,						Percent			Years Ended December 31,						Percent
(amounts in thousands)	2007		2006		Decrease		Change			2006		2005		Increase		Change
	$	685	$	1,032	$	347		34	%	$	1,032	$	137	$	895		653	%

Interest income includes amounts earned on the Company’s funds held in various cash operating and escrow accounts. Other income includes amounts earned from sub-tenant rental revenue from three sub-tenants. Interest income decreased $0.3 million in 2007 primarily due to the Company receiving a $0.3 million settlement of a bankruptcy claim in 2006 from a former tenant that vacated its lease in 2003 prior to expiration. The Company maintained a lower average cash balance in 2007 compared to 2006 primarily as a result of increased development, redevelopment and capital improvement activities. The Company earned an interest rate of 5.20% on an average cash balance of $4.2 million during 2007, compared to 5.00% on an average cash balance of $6.4 million during 2006.

Interest income increased $0.9 million in 2006 from 2005 primarily due to maintaining higher average cash balances and increased interest rates. The Company earned an interest rate of 5.00% on an average cash balance of $6.4 million during 2006, compared to 2.47% on an average cash balance of $1.6 million during 2005. In 2006, the Company received a $0.3 million settlement of a bankruptcy claim from a former tenant that vacated its lease in 2003 prior to expiration, which is included in other income. In addition, in 2006 the Company earned $0.2 million in sub-tenant rental revenue associated with the sub-lease of its former corporate offices from three sub-tenants.

Loss on interest-rate lock agreement is summarized as follows:


	Years Ended December 31,						Percent		Years Ended December 31,						Percent
(amounts in thousands)	2007		2006		Decrease		Change		2006		2005		Increase		Change
	$	—	$	671	$	671		—	$	671	$	—	$	671		—

In May 2006, the Company entered into a forward Treasury Lock Agreement (“treasury lock”) to lock-in the interest rate on an anticipated future debt issuance that subsequently closed in June 2006. The intent of the treasury lock was to minimize the risk of rising interest rates during the period prior to issuance. The derivative did not qualify for hedge accounting treatment, and upon the cash settlement of the contract in June 2006, the Company recognized the $0.7 million change in fair value as an expense.

Loss on early retirement of debt is summarized as follows:


	Years Ended December 31,						Percent		Years Ended December 31,						Percent
(amounts in thousands)	2007		2006		Decrease		Change		2006		2005		Decrease		Change
	$	—	$	121	$	121		—	$	121	$	2,546	$	2,425		95	%

In February 2006, the Company entered into a $50.0 million Term Loan Agreement to fund acquisitions and partially pay down the Company’s unsecured revolving credit facility. The Company paid off the term loan with proceeds from its Senior Notes issuance. The early repayment resulted in a $0.1 million loss on early retirement of debt during 2006 due to the write-off of deferred financing costs.

In July 2005, the Company closed on a $100.0 million fixed-rate secured financing with Jackson National Life Insurance Company. The loan was funded in two stages with proceeds from the first funding used to repay all of the Company’s floating rate mortgage debt and reduce the balance outstanding on its unsecured revolving credit facility. The Company incurred a $0.1 million charge associated with the write-off of unamortized financing costs on the debt retired. Proceeds from the second funding were used to satisfy the obligation under a mortgage loan maturing in December 2007 and bearing interest at 7.26%. The Company incurred a $2.8 million charge related to the costs associated with satisfying the obligation under this loan and writing off unamortized financing costs. Included in the charge was $0.3 million associated with the mortgage that encumbered 6600 Business Parkway, which was reclassified to income from discontinued operations.

Minority interests reflect the ownership interests of the Operating Partnership held by parties other than the Company. The decrease in minority interest expense in 2007 compared to 2006 can be attributed to a $2.0 million reduction in income from continuing operations. The outstanding interests owned by limited partners also decreased to 3.2% as of December 31, 2007 from 3.8% as of December 31, 2006, as a result of Operating Partnership unit redemptions. During 2007, 25,000 Operating Partnership units were redeemed for 25,000 common shares and 180,580 Operating Partnership units were purchased by the Company for $5.2 million in cash. The decline in minority interest ownership was partially offset by the issuance of 72,159 Operating Partnership units used to partially fund the acquisition of Annapolis Commerce Park East.

Minority interest expense increased in 2006 compared to 2005 due to a $1.4 million increase in income from continuing operations, which was primarily driven by the impacts of the 2005 and 2006 Acquisitions. The outstanding interests owned by limited partners decreased to 3.8% as of December 31, 2006 from 6.5% as of December 31, 2005, which is primarily attributable to the redemption of 462,135 Operating Partnership units in 2006 and the Company’s common stock offering of 3,450,000 common shares in July 2006.

During May 2006, the Company sold 6600 Business Parkway located in Elkridge, Maryland and recognized a gain on sale of $7.5 million. The Company has had no continuing involvement with this building; therefore the property’s operating results are classified as discontinued operations. Income from discontinued operations in 2005 represented the property operating results of 6600 Business Parkway. The Company had not committed to a disposition plan nor had it disposed of any additional real estate assets as of December 31, 2007.

Comparison of the Years Ended December 31, 2007 and 2006

Net cash provided by operating activities increased $5.0 million in 2007. This increase was largely the result of an increase in operating income before depreciation and amortization from the 2007 and 2006 Acquisitions.

Net cash used in investing activities decreased $90.8 million in 2007 as a result of fewer property acquisitions. In 2007, the Company purchased six properties for a total purchase price of $88.6 million, which includes the assumption of mortgage debt fair valued at $8.9 million and the issuance of Operating Partnership units valued at $1.7 million, compared to 14 properties acquired during 2006 for a total purchase price of $237.6 million, which includes the assumption of mortgage debt fair valued at $37.5 million. The decrease in property acquisitions was partially offset by an increase in development activity spending of $8.4 million in 2007 compared to 2006. During 2006, the Company received net proceeds of $15.4 million from the sale of 6600 Business Parkway. The Company had no property sales during 2007.

Net cash provided by financing activities decreased $170.0 million in 2007 as a result of lower proceeds from borrowings during the year. During 2007, net proceeds from borrowings totaled $138.0 million, compared to net proceeds from borrowings of $334.9 million in 2006. The 2007 borrowings include proceeds from the $50 million secured term loan issuance and borrowings under the unsecured revolving credit facility. The 2006 borrowings include proceeds from the $75 million and $125 million senior note issuances, with the remaining proceeds drawn on the unsecured revolving credit facility. The additional borrowings in 2006 were a result of greater property acquisitions during the year. The Company received net proceeds of $90.0 million from the July 2006 common share offering. The Company repaid borrowings of $59.6 million in 2007 compared to the repayment of borrowings of $180.1 million in 2006. The Company also purchased a capped call option for $7.6 million concurrent with the issuance of the $125 million Exchangeable Senior Notes in December 2006. During 2007, the Company purchased $5.2 million of additional Operating Partnership units. In 2007, the Company paid dividends to shareholders of $32.9 million compared to $27.5 million in 2006.

Comparison of the Years Ended December 31, 2006 and 2005

Net cash provided by operating activities increased $10.9 million in 2006. This increase was largely the result of an increase in operating income before depreciation and amortization from the 2006 and 2005 Acquisitions.

Net cash used in investing activities increased $62.1 million in 2006 primarily as a result of funding the cash portion of the 2006 Acquisitions, which were acquired for a total purchase price of $237.6 million, including mortgage debt assumed as part of the acquisitions with a total fair value of $37.5 million. In 2006, the Company received net proceeds of $15.4 million from the sale of 6600 Business Parkway. The Company had no property sales during 2005. The Company also commenced significant development activities on various development efforts through investing $5.4 million during 2006, largely in the John Marshall Highway addition and Sterling Park Business Center projects.

Net cash provided by financing activities increased $88.4 million in 2006 from net proceeds on borrowings of $334.9 million incurred to finance acquisitions and repay outstanding debt, compared to net proceeds on borrowings of $286.9 million in 2005. The 2006 borrowings include proceeds from the $75 million and $125 million Senior Note issuances, with the remaining proceeds drawn on the unsecured revolving credit facility. The Company received net proceeds of $90.0 million from the July 2006 common share offering and repaid borrowings of $180.1 million in 2006 compared to offering proceeds received and repayment of borrowings of $124.0 million and $271.5 million, respectively, in 2005. The Company also purchased a capped call option for $7.6 million concurrent with the issuance of the $125 million Exchangeable Senior Notes in December 2006. Finally, the Company paid dividends to shareholders of $27.5 million in 2006 compared to $19.0 million in 2005.

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 owned by the Company for the entirety of the periods presented, is a primary performance measure the Company uses to assess the results of operations at its properties. 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, and include real estate taxes and insurance capitalized during redevelopment periods, as these items vary significantly period over period thus impacting trends and comparability. Also, the Company eliminates depreciation and amortization expense, which are property level expenses, in computing Same Property NOI as these are non-cash expenses that are based on historical cost accounting and 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.

Same property NOI for the Southern Virginia properties decreased $0.2 million for the twelve months ended December 31, 2007 compared to the same period in 2006. Same property rental revenue decreased $0.1 million during 2007 as the result of a greater amount of deferred market revenue being recognized in 2006 for leases that ended prior to their contractual term, offset in part by higher average occupancy. Tenant reimbursement revenue increased $0.2 million during the twelve months ended December 31, 2007 as higher average occupancy resulted in greater recoveries. Same property operating expenses increased $0.3 million during full year 2007 due to increased repairs and maintenance expense and higher utility costs, while real estate taxes and insurance remained relatively unchanged.

Same Property NOI increased $1.5 million, or 3.2%, in 2006 over 2005. Same property rental revenue increased $0.9 million, or 1.5%, in 2006 as a result of higher rental rates on new and renewal leases, while occupancy remained relatively unchanged. Tenant reimbursement and other revenue increased $1.0 million, or 11.1%, generally reflecting the Company’s conversion of many new and renewal leases to a triple-net basis whereby a higher percentage of operating expenses are recovered. Total Same Property operating expenses increased $0.4 million, or 2.1%, due substantially to higher variable operating costs, with a portion attributable to the deregulation of utility contracts on our Maryland properties prior to the Company entering into fixed-rate utility contracts in late 2006. The increase in property operating expense was more than offset by the increase in tenant reimbursement revenue as a result of the increase in triple-net leases.

Same property NOI for the Southern Virginia properties increased $0.1 million for the twelve months ended December 31, 2006 compared to the same period in 2005. Same property rental revenue increased $0.3 million for the twelve months ended December 31, 2006 compared to the same periods in 2005 due to an increase in occupancy. Tenant reimbursement revenue remained relatively unchanged during the twelve months ended December 31, 2006. Same property operating expenses increased $0.2 million during full year 2007 due to an increase in non-recoverable expenses, which was slightly offset by decrease in real estate taxes and insurance.

Liquidity and Capital Resources

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. As a REIT, the Company is required to distribute at least 90% of its taxable income to its shareholders on an annual basis. The Company also regularly requires capital to invest in its existing portfolio of operating assets for capital projects. These capital projects include routine capital improvements and maintenance and leasing-related costs, including tenant improvements and leasing commissions.

On February 27, 2006, the Company entered into a $50.0 million Term Loan Agreement with Key Bank, N.A. The loan had a five-year term maturing in March 2011 with interest payable at a variable interest rate of LIBOR plus a spread determined by the Company’s leverage levels. Proceeds from the loan were used to partially fund acquisitions and pay down a portion of the Company’s unsecured revolving credit facility. The Company repaid this loan in June 2006 using proceeds from the private placement of Senior Notes discussed below.

On April 26, 2006, the Company entered into an amendment and restatement to its unsecured revolving credit facility, which increased the permitted borrowings under the facility from $100.0 million to $125.0 million. The facility, which was scheduled to mature in May 2009, has a feature that allows the Company to increase the size of the facility to up to $225.0 million. Borrowings on the facility bear interest at 120 to 160 basis points over LIBOR depending on the Company’s overall leverage levels. The exact interest payable under the facility depends upon the ratio of our total indebtedness to total asset value, and this ratio cannot exceed 65%. The Company is required to pay an annual commitment fee of 0.15% based on the amount of unused capacity under the credit facility.

On April 4, 2007, the Company further amended its unsecured revolving credit facility, which extended the facility’s maturity date to April 26, 2010, with the ability to further extend the maturity date to April 26, 2011. Also, the first amendment lowered the Company’s permitted maximum total indebtedness from 65% to 60% of its total asset value, as defined in its credit facility agreement, and lowered the interest rate spread from 120 to 160 basis points over LIBOR to 80 to 135 basis points over LIBOR. The unsecured facility contains financial and other covenants. As of December 31, 2007, the Company met all requirements under these covenants.

On June 22, 2006, the Operating Partnership completed a private placement of unsecured Senior Notes totaling $75.0 million. The transaction comprised of $37.5 million in 7-year Series A Senior Notes, maturing on June 15, 2013, bearing a fixed interest rate of 6.41% and $37.5 million in 10-year Series B Senior Notes, maturing on June 15, 2016, bearing a fixed interest rate of 6.55%. Interest is payable for the Series A and Series B Senior Notes on June 15 and December 15 of each year beginning on December 15, 2006. The Senior Notes are equal in right of payment with all the Company’s other senior unsubordinated indebtedness. The proceeds from the issuance of the Senior Notes were used to repay the outstanding $50.0 million term loan, described above, and to fund a portion of the purchase price of fourteen buildings in Richmond, Virginia. The unsecured facility contains financial and other covenants. As of December 31, 2007, the Company met all requirements under these covenants.

On July 21, 2006, the Company completed an offering of 3,450,000 common shares of beneficial interest at $27.46 per share, generating net proceeds of approximately $90.0 million. The Company used $55.5 million of the net proceeds to repay the balance and accrued interest on its unsecured revolving credit facility and the remaining proceeds were applied toward the purchase of Gateway 270.

On December 11, 2006, the Operating Partnership issued $125.0 million of 4.00% Exchangeable Senior Notes for net proceeds of approximately $122.2 million, net of a $2.8 million discount at issuance resulting in an effective interest rate of 4.45%. The Company used $73.6 million of the net proceeds from the Exchangeable Senior Notes issuance to repay the outstanding balance on its unsecured revolving credit facility, including accrued interest, and $7.6 million of the proceeds to purchase a capped call option. The capped call option is designed to reduce the potential dilution of common shares upon the exchange of the notes and protects the Company against any dilutive effects of the conversion feature if the market price of the Company’s common shares is between $36.12 and $42.14 per share. This option allows the Company to receive shares of the Company’s common stock from a counterparty equal to the amount of common stock and/or cash related to the excess conversion value that the Company would pay the holders of the Exchangeable Senior Notes upon conversion. The Company applied the majority of the remaining proceeds toward the January 2007 purchase of three buildings at Greenbrier Business Center. The Exchangeable Senior Notes contain financial and other covenants. As of December 31, 2007, the Company met all requirements under these covenants.

In March 2008, the Board of Trustees authorized the Company to use up to $30 million to repurchase its Exchangeable Senior Notes. In early March 2008, the Company agreed to terms to repurchase $13.75 million of the Exchangeable Senior Notes from a third party, with settlement anticipated to occur in mid-March 2008.

On August 7, 2007, the Company entered into a $50.0 million Secured Term Loan with Key Bank, N.A. The loan, which matures on August 7, 2010, has a one-year extension option and can be expanded to $100.0 million. The interest rate on the loan adjusts on a monthly basis, at which time all outstanding interest on the loan is payable. Borrowings on the loan bear interest at 70 to 125 basis points over LIBOR, depending on the Company’s overall leverage. The Company received proceeds of $49.6 million from the transaction, which were used to pay down a portion of the Company’s unsecured revolving credit facility and the related interest. As of December 31, 2007, the Company met all covenants of the secured term loan. In January 2008, the Company entered into a $50 million interest rate swap to hedge the interest rate exposure on its one month LIBOR based borrowings. The interest rate swap is an effective hedge that fixes the Company’s underlying interest rate on a $50 million notional balance at 2.71% plus a spread of 0.70% to 1.25% (depending on the Company’s overall leverage level), for a total rate ranging from 3.41% to 3.96%. The Secured Term Loan contains financial and other covenants. As of December 31, 2007, the Company met all requirements under these covenants.

Although the recent uncertainty in the global credit markets has had varying impacts that have negatively impacted debt financing and the availability of capital across many industries, the Company anticipates that its available cash flow from operating activities, and available cash from borrowings and other sources, will be adequate to meet its capital and liquidity needs in both the short and long term.

The Company intends to meet long-term funding requirements for building acquisitions, development, redevelopment and other non-recurring capital improvements through net cash from operations, long-term secured and unsecured indebtedness, including borrowings under its unsecured revolving credit facility, term loans, unsecured notes and the issuance of equity and debt securities. The Company’s ability to raise funds through sales of debt and equity securities is dependent on, among other things, general economic and 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.

On April 16, 2007, the Company filed a shelf registration statement with the Securities and Exchange Commission by which it registered an unspecified amount of senior debt securities, subordinated debt securities, preferred shares and common shares. The registration permits the Company to offer and sell these types of securities from time to time on a continuous basis under Rule 415 of the Securities Act of 1933, as amended.

The Company could also fund building acquisitions, development and other non-recurring capital improvements through additional borrowings, sales of assets or joint ventures. The Company could also issue units of partnership interest in the Operating Partnership to fund a portion of the purchase price for some of its future building acquisitions. During 2007, the Company issued 72,159 Operating Partnership units as partial consideration for the acquisition of Annapolis Commerce Park East.

Borrowings on the loan bear interest at 70 to 125 basis points over LIBOR, depending on the Company’s overall leverage. In January 2008, the Company entered into an interest rate swap that fixes the secured term loan’s interest rate at 2.71% plus a spread of 0.70% to 1.25% (depending on the Company’s overall leverage level) for a total rate ranging from 3.41% to 3.96%.

All of our outstanding debt contains customary, affirmative covenants including financial reporting, standard lease requirements and certain negative covenants, all of which the Company was in compliance with as of December 31, 2007. The Company is also subject to cash management agreements with most of its mortgage lenders. These agreements require that revenue generated by the subject property be deposited into a clearing account and then swept into a cash collateral account for the benefit of the lender from which cash is distributed only after funding of improvement, leasing and maintenance reserves and payment of debt service, insurance, taxes, capital expenditures and leasing costs.

Derivative Financial Instruments

In the normal course of business, the Company is exposed to the effect of interest rate changes. The Company has entered into derivative agreements to mitigate exposure to unexpected changes in interest rates and has used interest rate protection or cap agreements to reduce the impact of interest rate changes. The Company will only enter into these agreements with highly rated institutional counterparts.

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 with the offset to accumulated other comprehensive income in shareholders’ equity for effective hedging relationships. Derivative transactions that do not qualify for hedge accounting treatment or are considered ineffective will result in changes in fair value recognized in earnings.

In May 2006, the Company entered into a forward treasury lock agreement to effectively lock the interest rate in anticipation of a planned debt issuance in an effort to minimize the risk of rising interest rates during the period prior to issuance. The Company closed out the derivative in June 2006 upon the pricing of the $75.0 million Senior Notes and settled the contract with a cash payment of $0.7 million to the counterparty.

On December 11, 2006, the Operating Partnership issued $125.0 million of 4.00% Exchangeable Senior Notes for net proceeds of approximately $122.2 million, net of a $2.8 million discount at issuance resulting in an effective interest rate of 4.45%. The Company used $73.6 million of the net proceeds from the Exchangeable Senior Notes issuance to repay the outstanding balance on its unsecured revolving credit facility, including accrued interest, and $7.6 million of the proceeds to purchase a capped call option. The capped call option is designed to reduce the potential dilution of common shares upon the exchange of the notes and protects the Company against any dilutive effects of the conversion feature if the market price of the Company’s common shares is between $36.12 and $42.14 per share. This option allows the Company to receive shares of the Company’s common stock from a counterparty equal to the amount of common stock and/or cash related to the excess conversion value that the Company would pay the holders of the Exchangeable Senior Notes upon conversion. The option was recorded as a reduction to shareholders’ equity.

In January 2008, the Company entered into a $50 million interest rate swap to hedge the interest rate exposure on its one-month LIBOR based borrowings. The interest rate swap is an effective hedge that fixes the Company’s underlying interest rate on a $50 million notional balance at 2.71% plus a spread of 0.70% to 1.25% (depending on the Company’s overall leverage level), for a total rate ranging from 3.41% to 3.96%.The interest rate swap expires in August 2010, concurrent with the maturity of the Company’s Secured Term Loan.

Off-Balance Sheet Arrangements

The Company was not a party to any joint venture agreements and had no off-balance sheet arrangements as of December 31, 2007 or 2006.

¹		Total carrying value of the Exchangeable Senior Notes was $122,797, net of discount, at December 31, 2007.

²		Interest expense for the Company’s fixed rate obligations represents the amount of interest that is contractually due under the terms of the respective loans. Interest expense for the Company’s variable rate obligations is calculated using the outstanding balance and applicable interest rate at December 31, 2007 over the life of the obligation.

Development contractual obligations include commitments primarily related to the construction of an office building at Sterling Park Business Center. Redevelopment contractual obligations include commitments to another building at Sterling Park Business Center. Capital expenditure obligations represent commitments for roof, asphalt, HVAC and common area replacements contractually obligated as of December 31, 2007. Tenant improvement obligations include costs the Company expects to incur on leases in place at December 31, 2007. The Company had no other material contractual obligations as of December 31, 2007.

Funds From Operations

Many investors and analysts following the real estate industry use funds from operations (“FFO”) as a supplemental performance measure. Management considers FFO an appropriate supplemental 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 adds back minority interest in the income from its Operating Partnership on 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 fully diluted share.

FFO should not be viewed as a substitute to net income as a measure of the Company’s operating performance since it does not reflect either depreciation and amortization costs or the level of capital expenditures and leasing costs necessary to maintain the operating performance of the Company’s properties, which are significant economic costs that could materially impact the Company’s results of operations.

The following table presents a reconciliation of net income to FFO available to common share and unit holders (amounts in thousands):

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; and other risks detailed under “Risk Factors” in Part I, Item 1A of this Annual Report on Form 10-K. 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 7A. QUANTITATIVE AND QUALITATIVE 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. Market risk refers to the risk of loss from adverse changes in market interest rates. The Company uses derivative financial instruments 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.

As of December 31, 2007, the Company had $88.6 million, or 13.1% of its total debt obligations, in variable rate debt. The carrying value of the variable rate debt reflects its fair value as changes in the underlying interest rate reflect the impact of market conditions on the outstanding balances.

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. The Company estimates the fair value of its fixed rate debt outstanding at December 31, 2007 to be $559.0 million compared to the $587.9 million carrying value at that date.

In December 2006, and concurrent with the issuance of $125.0 million of Exchangeable Senior Notes, the Company purchased, for $7.6 million, a capped call option on its common shares in a separate transaction. The notes are exchangeable into the Company’s common shares at an initial rate of 27.6855 shares for each $1,000 of principal amount of the notes for a total of approximately 3.5 million shares, which is equivalent to an initial exchange price of $36.12 per Company common share. The capped call option is designed to reduce the potential dilution of common shares upon the exchange of the notes and protects the Company against any dilutive effects of the conversion feature if the market price of the Company’s common shares is between $36.12 and $42.14 per share. This option allows the Company to receive shares of the Company’s common stock from a counterparty equal to the amount of common stock and/or cash related to the excess conversion value that the Company would pay the holders of the notes upon conversion. The option will terminate upon the earlier of the maturity date of the notes or the first day in which the notes are no longer outstanding due to conversion or otherwise. The option was recorded as a reduction of shareholders’ equity.

Management’s Report on Internal Control Over Financial Reporting

The Company is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is a process designed under the supervision of our principal executive and principal financial officers to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles.

As of December 31, 2007, management conducted an assessment of the effectiveness of our internal control over financial reporting based on the framework established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, management has determined that our internal control over financial reporting as of December 31, 2007 was effective.

Our internal control over financial reporting includes policies and procedures that pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of assets; provide reasonable assurances that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of the Company’s management and trustees; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.

There were no changes in the Company’s internal control over financial reporting during the quarter ended December 31, 2007 that have materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Our internal control over financial reporting as of December 31, 2007 has been audited by KPMG, LLP, an independent registered public accounting firm, as stated in their attestation report appearing on page 54 which expresses an unqualified opinion on the effectiveness of our internal control over financial reporting as of December 31, 2007.

Report of Independent Registered Public Accounting Firm

The Board of Trustees and Shareholders
First Potomac Realty Trust:

We have audited First Potomac Realty Trust’s internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). First Potomac Realty Trust’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, First Potomac Realty Trust maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of First Potomac Realty Trust as of December 31, 2007 and 2006, and the related consolidated statements of operations, shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2007, and our report dated March 7, 2008, expressed an unqualified opinion on those consolidated financial statements.

Report of Independent Registered Public Accounting Firm

The Board of Trustees and Shareholders
First Potomac Realty Trust:

We have audited the accompanying consolidated balance sheets of First Potomac Realty Trust and subsidiaries as of December 31, 2007 and 2006, and the related consolidated statements of operations, shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2007. In connection with our audits of the consolidated financial statements, we also have audited the financial statement schedule of real estate and accumulated deprecation. These consolidated financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of First Potomac Realty Trust and subsidiaries as of December 31, 2007 and 2006, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2007, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

As discussed in note 2 to the consolidated financial statements, the Company adopted Statement of Financial Accounting Standards No. 123(R), Share-Based Payment in 2006.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), First Potomac Realty Trust’s internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 7, 2008, expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

FIRST POTOMAC REALTY TRUST AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) Description of Business

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

The Company owns all of its properties and conducts its business through First Potomac Realty Investment Limited Partnership; the Company’s operating partnership (the “Operating Partnership”). At December 31, 2007, the Company was the sole general partner of, and owned a 96.8% interest in, the Operating Partnership. The remaining interests in the Operating Partnership consist of limited partnership interests owned by third parties, including some of the Company’s executive officers and trustees who contributed properties and other assets to the Company upon its formation, and are presented as minority interests in the accompanying consolidated financial statements.

As of December 31, 2007, the Company owned approximately 11.4 million square feet. The Company also owned developable land that can accommodate approximately 1.6 million square feet of development. 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 consolidated financial statements of the Company include the accounts of the Company, the Operating Partnership, the subsidiaries of the Operating Partnership and First Potomac Management LLC, a wholly owned subsidiary that manages the Company’s properties. All intercompany balances and transactions have been eliminated in consolidation.

(b) Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“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 financial statements and the reported amounts of revenues and expenses during the period. Actual results could differ from those estimates.

(c) Revenue Recognition

The Company generates substantially all of its revenue from leases on its industrial properties and business parks. The Company recognizes rental revenue on a straight-line basis over the life of its leases in accordance with SFAS No. 13, Accounting for Leases. 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 and 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.

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 that 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.

(d) Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity of 90 days or less at the date of purchase to be cash equivalents.

(e) Escrows and Reserves

Escrows and reserves represent cash restricted for debt service, real estate taxes, insurance, capital items and tenant security deposits.

(f) Deferred Costs

Financing costs related to long-term debt are deferred and amortized over the remaining life of the debt using a method that approximates the interest method. Leasing costs related to the execution of tenant leases are deferred and amortized over the term of the related leases. Accumulated amortization of these combined costs was $5.9 million and $3.5 million at December 31, 2007 and 2006, respectively.

(g) Rental Property

Rental property is carried at historical cost less accumulated depreciation and, when appropriate, impairment losses. Improvements and replacements are capitalized at historical 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 of rental property is computed 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 15 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 reviews market conditions for possible impairment of a property’s carrying value. When circumstances such as adverse market conditions or changes in management’s intended holding period indicate a possible impairment of the value of a property, an impairment analysis is performed. The Company assesses the recoverability based on an estimate of the future undiscounted cash flows (excluding interest charges) expected to result from the real estate investment’s use and eventual disposition. This estimate is based on projections of future revenues, expenses and capital improvement costs. These cash flows consider factors such as expected market trends and 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, 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 subjective assessments as to whether there are impairments in its investments in real estate.

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. If these criteria are met, the Company will record an impairment loss if the fair value, less selling costs, is lower than the carrying amount of the property. The Company will classify any impairment loss, together with the building’s operating results, as discontinued operations on its statements of operations and classify the assets and related liabilities as held for sale on its balance sheet. Interest expense is reclassified to discontinued operations only to the extent the held for sale property is secured by specific mortgage debt.

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 SFAS No. 34, Capitalization of Interest Cost. 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. Capitalization of interest will end when the asset is substantially complete and ready for its intended use. Total interest capitalized to construction in progress was $1.3 million and $0.3 million during 2007 and 2006, respectively. No interest expense was capitalized during 2005 as the Company had not incurred any qualifying expenditures. Capitalized interest is depreciated over the useful life of the underlying assets, commencing when those assets are placed into service.

(h) Purchase Accounting

Acquisitions of rental property from third parties are accounted for at fair value, which 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 purchase price is also allocated as follows:

	§		the value of leases based on the leasing origination costs at the date of the acquisition, which approximates the market value of the lease origination costs had the in-place leases been originated on the date of acquisition; the value of in-place leases represents absorption costs for the estimated lease-up period in which vacancy and foregone revenue are incurred;

	§		the value of above and below market in-place lease values 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 lease and the estimated fair market lease rates for the corresponding spaces over the remaining non-cancelable terms of the related leases, which range from one to twenty years; and

	§		the intangible value of tenant or customer relationships.

The Company’s determination of these 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.

(i) Intangible Assets

Intangible assets include the value of acquired tenant or customer relationships and the in-place value of leases in accordance with SFAS No. 141, Business Combinations (“SFAS 141”). Customer relationship values are determined based on our evaluation of the specific characteristics of each tenant’s lease and our overall relationship with the tenant. Characteristics the Company considers include the nature and extent of its existing business relationships with the tenant, growth prospects for developing new business with the tenant, the tenant’s credit quality and expectations of lease renewals. The value of customer relationship intangible assets is amortized to expense over the lesser of the initial lease term and any expected renewal periods or the remaining useful life of the building. The Company determines the fair value of the existing leases at the date of acquisition by estimating the leasing commissions avoided by having in-place tenants and the operating income that would have been lost during the estimated time required to lease the space occupied by existing tenants at the acquisition date. The cost of acquiring existing tenants is amortized to expense over the initial term of the respective leases. Should a tenant terminate its lease, the unamortized portion of the in-place lease value is fully charged to expense by the date of termination.

Deferred market rent liability consists of the acquired leases with below-market rents at the date of acquisition. The value attributed to deferred market rent assets, which consist of above-market rents at the date of acquisition, is recorded as a component of deferred costs. Above and below market in-place lease values are determined on a lease-by-lease basis based on the present value (using a discounted rate that reflects the risks associated with the acquired leases) of the difference between the contractual rent amounts to be paid under the lease and the estimated fair market lease rates for the corresponding spaces over the remaining non-cancelable terms of the related leases. The capitalized below-market lease values are amortized as an increase to rental revenue over the initial term and any below-market renewal periods of the related leases. Capitalized above-market lease values are amortized as a decrease to rental revenue over the initial term of the related leases. The total accumulated amortization of intangible assets was $24.3 million and $25.2 million at December 31, 2007 and 2006, respectively.

In conjunction with the Company’s initial public offering and related formation transactions, First Potomac Management, Inc. contributed all of the capital interests in First Potomac Management LLC, the entity that manages the Company’s properties, to the Operating Partnership. The $2.1 million fair value of the in-place workforce acquired has been classified as goodwill in accordance with SFAS 141 and is included as a component of intangible assets on the consolidated balance sheet. In accordance with SFAS No. 142, Goodwill and Other Intangibles (“SFAS 142”) all acquired goodwill that relates to the operations of a reporting unit and is used in determining the fair value of a reporting unit is allocated to the Company’s appropriate reporting unit in a reasonable and consistent manner. The Company assesses goodwill for impairment annually at the end of its fiscal year and in interim periods if certain events occur indicating the carrying value is impaired. The Company performs its analysis for potential impairment of goodwill in accordance with SFAS 142, which requires that a two-step impairment test be performed on goodwill. In the first step, the fair value of the reporting unit is compared to its carrying value. If the fair value exceeds its carrying value, goodwill is not impaired, and no further testing is required. If the carrying value of the reporting unit exceeds its fair value, then a second step must be performed in order to determine the implied fair value of the goodwill and compare it to the carrying value of the goodwill. If the carrying value of goodwill exceeds its implied fair value then an impairment loss is recorded equal to the difference. No impairment losses were recognized during the years ended December 31, 2007, 2006 and 2005.

(j) Derivatives and Hedging

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 will only enter into these agreements with highly rated institutional counterparts.

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 with the offset to accumulated other comprehensive income, located in shareholders’ equity (cash flow hedge) or a corresponding asset or liability (fair value hedge) for effective hedging relationships. Ineffective portions of derivative transactions will result in changes in fair value recognized in earnings.

In December 2006, and concurrent with the issuance of $125.0 million of Exchangeable Senior Notes, the Company purchased a capped call option on its common stock. The capped call option is designed to reduce the potential dilution of common shares upon the exchange of the notes and protects the Company against any dilutive effects of the conversion feature if the market price of the Company’s common shares is between $36.12 and $42.14 per share. This option allows the Company to receive shares of the Company’s common stock from a counterparty equal to the amount of common stock and/or cash related to the excess conversion value that the Company would pay the holders of the notes upon conversion. The option will terminate upon the earlier of the maturity date of the notes or the first day in which the notes are no longer outstanding. The option was recorded as a reduction of shareholders’ equity.

In May 2006, the Company entered into a forward treasury lock agreement to fix the interest rate in anticipation of a planned debt issuance and hedge the risk of rising interest rates during the period prior to issuance. The derivative did not qualify for hedge accounting treatment, and the Company recorded a $671 thousand loss upon the cash settlement of the contract in June 2006.

There were no other derivative contacts entered into in 2007, 2006 or 2005 and the Company had no accumulated other comprehensive income or loss related to derivatives during these respective periods.

(k) Income Taxes

The Company has elected to be taxed as a REIT. To maintain its status as a REIT, the Company is required to distribute at least 90% of its ordinary taxable income annually to its shareholders and meet other organizational and operational requirements. As a REIT, the Company will not be subject to federal income tax and any non-deductible excise tax if it distributes at least 100% of its REIT taxable income to its shareholders. If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal income tax on its taxable income at regular corporate tax rates. The Company had a taxable REIT subsidiary (“TRS”) that was inactive in 2007 and 2006. The Company had two TRS entities that generated taxable income during 2005; however, the Company determined any taxes resulting from TRS activities were inconsequential. In 2005, the two TRS entries contributed their ownership interest to the Company. This elimination of the TRS ownership interest resulted in a taxable distribution of property, and the Company recognized an estimated tax liability of $0.1 million in general and administrative expenses in 2005 as a result of the contribution of ownership interests by the TRS to the Operating Partnership.

For federal income tax purposes, dividends to shareholders may be characterized as ordinary income, return of capital or capital gains. The characterization of the Company’s dividends for 2007, 2006 and 2005 are as follows:


	2007			2006			2005
Ordinary income		45.10	%		41.43	%		40.03	%
Return of capital		54.90	%		58.57	%		57.25	%
Long-term capital gain		—			—			2.72	%

(l) Minority Interests

Minority 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 an equivalent amount of cash. Unitholders receive distributions per unit equivalent to the dividend per common share. Minority interests are recorded based on their fair value at issuance, adjusted for the minority interests’ share of net income or loss and distributions paid. Redemptions are recorded in accordance with EITF Issue No. 95-7 “Implementation Issues Related to the Treatment of Minority Interests in Certain Real Estate Investment Trusts.” Differences between amounts paid to redeem minority interests and their carrying values are charged or credited to shareholders’ equity.

The Company owned 96.8%, 96.2% and 93.5% of the outstanding Operating Partnership units at December 31, 2007, 2006 and 2005, respectively. During 2007, the Company issued 72,159 Operating Partnership units valued at $1.7 million to partially fund the acquisition of Annapolis Commerce Park East. There were also 25,000 Operating Partnership units redeemed for 25,000 common shares valued at $0.4 million and 180,580 Operating Partnership units were purchased for $5.2 million in cash resulting in 807,233 Operating Partnership units outstanding as of December 31, 2007. During 2006, 462,135 Operating Partnership units were redeemed for 462,135 common shares valued at $6.8 million and 1,000 Operating Partnership units were redeemed for $31 thousand in cash resulting in 940,654 Operating Partnership units outstanding as of December 31, 2006. During 2005, 300,429 Operating Partnership units valued at $7.7 million were issued with the acquisitions of Owings Mills Business Center and Prosperity Business Center, while 285,913 Operating Partnership units were redeemed for 285,913 common shares valued at $3.8 million resulting in 1,403,789 Operating Partnership units outstanding at December 31, 2005.

(m) Earnings Per Share

Basic earnings per share (“EPS”), is calculated by dividing net income 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. The effect of stock options, non-vested shares, Exchangeable Senior Notes and Operating Partnership units, if dilutive, is computed using the treasury stock method.

The following table sets forth the computation of the Company’s basic and diluted earnings per share both before and after consideration of income from discontinued operations and income available to common shareholders (amounts in thousands, except per share amounts):


	2007		2006		2005

Discontinued operations		—		0.34		0.01

Net income	$	0.02	$	0.45	$	0.08

In accordance with FAS No. 128, Earnings Per Share, the Company did not include the following anti-dilutive shares in its calculation of diluted earnings per share for the years ended December 31, (amounts in thousands).


	2007		2006		2005
Stock option awards		501		405		446
Non-vested share awards		85		58		57

		586		463		503

Approximately 3.5 million incremental shares from the assumed conversion of the $125 million Exchangeable Senior Notes, issued on December 11, 2006, were excluded from the Company’s earnings per share calculation as they were anti-dilutive.

(n) Share-Based Compensation

Effective January 1, 2006, the Company adopted the fair value recognition provisions of SFAS No. 123R, Share-Based Payment, (“SFAS No. 123R”), which require that the cost for all share-based payment transactions be recognized as a component of income from continuing operations. The statement requires a public entity to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award (with limited exceptions). That cost will be recognized over the period during which an employee is required to provide service in exchange for the award – the requisite service period (usually the vesting period).

Prior to January 1, 2006 and as permitted by SFAS No. 123, Accounting for Stock Based Compensation, the Company elected to follow the intrinsic value-based method of accounting prescribed by the Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations, in accounting for its fixed plan share options. As such, compensation expense would be recorded only if the market price of the underlying shares on the date of grant exceeded the exercise price.

The Company adopted SFAS No. 123R using the modified-prospective-transition method. Under this method, compensation cost for the year ended December 31, 2007 includes: (i) compensation cost for all share-based payments granted prior to, but not yet vested as of January 1, 2006, based on the grant-date fair value estimated in accordance with the original provisions of SFAS No. 123 and (ii) compensation cost for all share-based payments granted subsequent to January 1, 2006, based on the grant-date fair value estimated in accordance with the provisions of SFAS No. 123R. Results for prior periods have not been restated. The Company recognizes share-based compensation costs on a straight-line basis over the requisite service period for each award.

Under SFAS No. 123, compensation expense of $0.7 million would have been recorded during 2005 for our 2003 Equity Compensation Plan based upon the fair value of the awards.

Pro forma net income and net income per share for the year ended December 31, 2005 had compensation for stock options been determined based on the grant date fair value would have been as follows (amounts in thousands, except per share amounts):


	2005
Net income, as reported	$	1,350
Add: total stock-based employee compensation expense included in reported net income, net of minority interests		401
Deduct: total stock-based employee compensation expense determined under fair value based method for all awards, net of minority interests		(658	)

Pro forma net income	$	1,093


Net income per share, as reported – basic and diluted	$	0.08
Pro forma net income per share – basic and diluted	$	0.07

(o) Reclassifications

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

(p) Application of New Accounting Standards

In July 2006, the FASB issued FASB Interpretation Number 48, Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109, (“FIN 48”). FIN 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken in a tax return. The Company must determine whether it is “more-likely-than-not” that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Once it is determined that a position meets the more-likely-than not recognition threshold, the position is measured to determine the amount of benefit to recognize in the financial statements. FIN 48 applies to all tax positions related to income taxes subject to FASB Statement No. 109, Accounting for Income Taxes. The Company is structured to qualify as a REIT and, therefore, is not subject to federal income tax if it distributes 100% of its taxable REIT income to its shareholders. As the Company fully intends to meet the requirements to qualify as a REIT and to distribute 100% of its taxable REIT income, it does not record an income tax provision on its statement of operations or accrue any income tax liability. The Company adopted the provisions of FIN 48 on January 1, 2007 and the adoption of this statement did not have an impact on the Company’s financial statements.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements (“SFAS 157”). SFAS 157 clarifies the principle that fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. Under the standard, fair value measurements would be separately disclosed by level within the fair value hierarchy. SFAS 157 is effective for fiscal years beginning after November 15, 2007, with early adoption permitted. However, in February 2008, the FASB issued FSP FAS 157-2, which delays the effective date of SFAS 157 for all nonrecurring fair value measurements of nonfinancial assets and nonfinancial liabilities until fiscal years beginning after November 15, 2008. The Company does not expect the adoption of SFAS 157 to have a material impact on its financial statements.

In December 2007, the FASB issued Financial Accounting Standards No. 141R, Business Combinations, (“SFAS 141R”). SFAS 141R requires an entity to use the acquisition method (previously referred to as the purchase method) for all business combinations and for an acquirer to be identified for each business combination. Under the standard, equity instruments issued by the acquirer as consideration are measured at fair value on the acquisition date. Whether the acquirer acquires all or a partial interest in the acquiree, the full fair value of the assets acquired, liabilities assumed and noncontrolling interests is recognized. SFAS 141R is effective for fiscal years beginning on or after December 15, 2008, which would be effective for the Company’s fiscal year beginning January 1, 2009. SFAS 141R will affect the manner in which the Company accounts for property acquisitions subsequent to the effective date. However, the Company does not believe the adoption of SFAS 141R will have a material impact on its financial statements.

In December 2007, the FASB issued Financial Accounting Standards No. 160, Noncontrolling Interests in Consolidated Financial Statements, an Amendment of ARB No. 51, (“SFAS 160”). SFAS 160 requires that noncontrolling interests in subsidiaries held by parties other than the parent be treated as a separate component of equity, not as a liability or other item outside of equity. Also, the Company will report net income attributable to both controlling and noncontrolling interests. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008, which would be effective for the Company’s fiscal year beginning January 1, 2009. Had the Company implemented this standard, $11.5 million of the Company’s minority partners’ interest at December 31, 2007 would have been reclassified from the mezzanine section of the Company’s balance sheet into shareholders’ equity. Also, net income would have increased $20 thousand, $509 thousand and $109 thousand for 2007, 2006 and 2005, respectively. However, these amounts would have been deducted in the determination of net income available to common shareholders. The Company does not believe the implementation of this standard will have a material affect on its financial statements.

(3) Rental Property

Development and Redevelopment Activity

On April 1, 2007, the Company completed construction on a 112,000 square foot addition to an existing building at 15395 John Marshall Highway. The addition was fully pre-leased to the existing tenant and completed at a total cost of approximately $8.3 million. During the fourth quarter of 2007, the Company substantially completed a 45,000 square foot addition to an existing building at Crossways Commerce Center at a total cost of approximately $4.9 million; half of the addition was pre-leased to an existing tenant. Also, in the fourth quarter of 2007, the Company substantially completed a 96,000 square foot addition to an existing building at Cavalier Industrial Park at a total cost of approximately $5.4 million.

The Company intends to continue to construct industrial buildings and/or business parks on a build-to-suit basis or with the intent to lease upon completion of construction. At December 31, 2007, the Company had a total of approximately 0.3 million square feet under development or redevelopment, which consists of 0.1 million square feet in each of its three regions. The Company anticipates development and redevelopment efforts on these projects will continue throughout 2008.

At December 31, 2007, the Company owned developable land, which can accommodate approximately 1.6 million square feet of building, which includes 0.3 million square feet in its Maryland region; 0.6 million square feet in its Northern Virginia region; and 0.7 million square feet in its Southern Virginia region.

(6) Discontinued Operations

Income from discontinued operations represents revenues and expenses associated with 6600 Business Parkway, formerly in the Company’s Maryland reporting segment, which was sold in May 2006. The proceeds from the disposal were escrowed and used to fund subsequent acquisitions as part of a tax-free like-kind exchange. The Company has had no continuing involvement with the property subsequent to its disposal. Interest expense that is specifically identifiable to the disposed property is included in the presentation of income from discontinued operations. Interest expense for 2005 was associated with the allocable portion of interest for mortgage debt that encumbered 6600 Business Parkway and other properties. This mortgage obligation, including a one-time charge, was repaid in 2005; therefore no interest expense was associated with this property in 2006. The Company did not dispose of any properties during 2007.

⁵		Weighted average interest rate on total mortgage debt.

In February 2008, the Company prepaid the outstanding mortgage encumbering Herndon Corporate Center, including accrued interest, for $8.6 million. The payment was funded with borrowings of $8.0 million on the Company’s unsecured revolving credit facility and available cash. The mortgage was due to mature on April 1, 2008 and had a fixed interest rate of 5.11%. Deferred financing fees associated with the loan were inconsequential and no prepayment penalties were incurred.

In June 2007, the Company prepaid the outstanding mortgage encumbering Hanover Business Center - - Building B for $1.9 million of available cash. The mortgage was due to mature on June 15, 2016 and had a fixed interest rate of 4.0% at the time of prepayment, which was scheduled to convert to a variable interest rate on the date of prepayment. Deferred financing costs associated with the mortgage were inconsequential and no prepayment penalties were incurred on the transaction.

In October 2006, the Company repaid the $8.3 million remaining principal balance on the mortgage that encumbered Interstate Plaza. The repayment was funded with borrowings on the Company’s unsecured revolving credit facility, and no prepayment penalties were incurred.

The Company’s mortgage debt is recourse solely to specific assets. The Company had 45 and 44 properties that secured mortgage debt at December 31, 2007 and 2006, respectively.

(b) Exchangeable Senior Notes

On December 11, 2006, the Company issued $125.0 million of 4.00% Exchangeable Senior Notes for net proceeds of approximately $122.2 million, net of a $2.8 million discount at issuance resulting in an effective interest rate of 4.45%. The Exchangeable Senior Notes mature on December 15, 2011 and are equal in right of payment with all of the Company’s other senior unsubordinated indebtedness. Interest is payable on June 15 and December 15 of each year beginning on June 15, 2007. Holders may, under certain conditions, exchange their notes for cash or a combination of cash and the Company’s common shares, at the Company’s option, at any time after October 15, 2011. The Exchangeable Senior Notes are exchangeable into the Company’s common shares at an initial rate of 27.6855 shares for each $1,000 of principal amount of the notes for a total of approximately 3.5 million shares, which is equivalent to an initial exchange price of $36.12 per Company common share representing an exchange premium of approximately 20% over the market price of the Company’s common shares at the time of the transaction. The exchange rate is adjusted for, among other things, the payment of dividends to the Company’s common shareholders subject to a maximum exchange rate. Holders may exchange their notes prior to maturity under certain conditions, including during any calendar quarter beginning after December 31, 2006 (and only during such calendar quarter), if and only if, the closing sale price of the Company’s common shares for at least 20 trading days in the period of 30 trading days ending on the last trading day of the preceding quarter is greater than 130% of the exchange price on the applicable trading day. The Exchangeable Senior Notes have not been registered under the Securities Act and may not be traded or sold except to certain defined qualified institutional buyers. The notes are senior unsecured obligations of the Operating Partnership and guaranteed by the Company. As of December 31, 2007, the Company was in compliance with all of the covenants of its Exchangeable Senior Notes.

The Company used $73.6 million of the net proceeds from the Exchangeable Senior Notes issuance to repay the outstanding balance on its unsecured revolving credit facility, including accrued interest, and $7.6 million of the proceeds to then purchase a capped call option. The capped call option is designed to reduce the potential dilution of common shares upon the exchange of the notes and protects the Company against any dilutive effects of the conversion feature if the market price of the Company’s common shares is between $36.12 and $42.14 per share. This option allows the Company to receive shares of the Company’s common stock from a counterparty equal to the amount of common stock and/or cash related to the excess conversion value that the Company would pay the holders of the Exchangeable Senior Notes upon conversion. The option will terminate upon the earlier of the maturity date of the notes or the first day in which the notes are no longer outstanding due to conversion or otherwise. The option was recorded as a reduction of shareholders’ equity. To the extent the then market value per Company common share exceeds the cap price during the observation period relating to an exchange of notes, the reduction in potential dilution will be limited to the difference between the strike price and the cap price. The Company applied the majority of the remaining proceeds toward the January 2007 purchase of three buildings at Greenbrier Business Center.

(c) Senior Notes

On June 22, 2006, the Operating Partnership completed a private placement of unsecured Senior Notes totaling $75.0 million. The transaction was comprised of $37.5 million in 7-year Series A Senior Notes, maturing on June 15, 2013 and bearing a fixed interest rate of 6.41%, and $37.5 million in 10-year Series B Senior Notes, maturing on June 15, 2016 and bearing a fixed interest rate of 6.55%. Interest is payable for the Series A and Series B Senior Notes on June 15 and December 15 of each year beginning December 15, 2006. The Senior Notes are equal in right of payment with all the Operating Partnership’s other senior unsubordinated indebtedness. The proceeds from the issuance of the Senior Notes were used to repay outstanding indebtedness and to acquire 14 buildings in Richmond, Virginia. As of December 31, 2007, the weighted average interest rate on the Senior Notes was 6.48%. As of December 31, 2007, the Company was in compliance with all the covenants of its Senior Notes.

(d) Secured Term Loan

In January 2008, the Company entered into a $50 million interest rate swap to hedge the interest rate exposure on its one month LIBOR based borrowings. The interest rate swap is an effective hedge that fixes the Company’s underlying interest rate on a $50 million notional balance at 2.71% plus a spread of 0.70% to 1.25% (depending on the Company’s overall leverage level), for a total rate ranging from 3.41% to 3.96%. The interest rate swap expires in August 2010, concurrent with the maturity of the Company’s Secured Term Loan.

The Company’s Secured Term Loan contains several restrictive covenants, which in the event of non-compliance may cause the outstanding balance of loan to become immediately payable. The various Secured Term Loan covenants include maintaining a borrowing base debt service coverage ratio (as defined in the Secured Term Loan agreement) above 1.4 to 1.0 and a borrowing base pool leverage (as defined in the Secured Term Loan agreement) below a specified threshold. As of December 31, 2007, the Company was in compliance with all the covenants of its Secured Term Loan.

(e) Unsecured Revolving Credit Facility

On April 26, 2006, the Company entered into an amendment and restatement to its unsecured revolving credit facility, which increased the permitted borrowings under the facility from $100.0 million to $125.0 million. The facility, which matures in May 2009, has a feature that allows the Company to increase the size of the facility to up to $225 million. Borrowings on the facility bear interest at 120 to 160 basis points over LIBOR depending on the Company’s overall leverage levels. The interest payable under the facility depends upon the ratio of the Company’s total indebtedness to total asset value, and this ratio cannot exceed 65%. The Company is required to pay an annual commitment fee of 0.15% based on the amount of unused capacity under the credit facility.

On April 4, 2007, the Company entered into an amendment to its unsecured revolving credit facility, which extended the facility’s maturity date by one year to April 26, 2010, with the ability to further extend the maturity date to April 26, 2011. Also, the first amendment lowered the Company’s permitted maximum total indebtedness from 65% to 60% of its total asset value, as defined in its credit facility agreement, and lowered the interest rate spread from 120 to 160 basis points over LIBOR to 80 to 135 basis points over LIBOR.

The weighted average borrowings outstanding on the credit facility during 2007 were $28.4 million with a weighted average interest rate of 6.49%, compared to $50.0 million and 6.47%, respectively, during 2006. The Company’s maximum daily borrowings outstanding were $64.0 million and $87.5 million during 2007 and 2006, respectively. Outstanding borrowings under the credit facility were $38.6 million with a weighted average interest rate of 5.8% at December 31, 2007. There were no borrowings outstanding under the credit facility at December 31, 2006. As of December 31, 2007, the Company was in compliance with all the covenants of its unsecured revolving credit facility.

In the opinion of management and the Company’s legal counsel, the amount of ultimate liability with respect to these actions will not have a material effect on the results of operations or financial position of the Company.

(9) Related Party Transaction

In September 2005, the Company subleased a portion of its former corporate office space to Donatelli Development, Inc. (formerly Donatelli & Klein), a privately held real estate investment firm that develops multifamily properties, which is owned by a member of the Company’s Board of Trustees. The rental rate under the sublease was representative of market rates on the date the sublease was executed. Rents due under the terms of the sublease are approximately $200 thousand per year over the remaining three years of the original lease. The Company remains obligated as primary lessee under the terms of the original lease.

(10) Fair Value of Financial Instruments

The carrying amounts of cash, accounts and other receivables and accounts payable approximate their fair values due to their short-term maturities. The carrying amounts of the line of credit and the Secured Term Loan approximate their fair value due to the variable nature of their respective interest rates. We calculate fair value of our other financial statements 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 these other financial instruments at December 31, 2007 and 2006 are as follows (amounts in thousands):

(11) Shareholders’ Equity

On July 21, 2006, the Company completed an offering of 3.5 million common shares of beneficial interest at $27.46 per share, generating net proceeds of approximately $90 million. The Company used $55.5 million of the net proceeds to pay down the balance and accrued interest on its unsecured revolving credit facility and the remaining proceeds were applied toward the purchase of Gateway 270.

The Company declared dividends per share on its common stock of $1.36, $1.24 and $1.125 during 2007, 2006 and 2005, respectively.

(12) Benefit Plans

(a) Share-based compensation

The Company has issued share-based compensation in the form of stock options and non-vested shares as permitted in the Company’s 2003 Equity Compensation Plan (“the Plan”). The Plan provides for the issuance of options to purchase common shares, share awards, share appreciation rights, performance units and other equity-based awards. Options granted under the plan are non-qualified, and all employees and non-employee trustees are eligible to receive grants. The Plan originally authorized the issuance of 910,800 common share equity awards. An additional 650,000 common shares of equity awards were authorized in 2005. Of the common share equity awards authorized under the Plan, 547,399 awards remained available for issuance under the Plan as of December 31, 2007.

Effective January 1, 2006, the Company adopted the fair value recognition provisions of SFAS No. 123R, Share-Based Payment, using the modified-prospective-transition method. Under this method, compensation cost for the years ended 2007 and 2006 include: (i) compensation cost for all share-based payments granted prior to, but not yet vested as of January 1, 2006, based on the grant-date fair value estimated in accordance with the original provisions of SFAS No. 123 and (ii) compensation cost for all share-based payments granted subsequent to January 1, 2006, based on the grant-date fair value estimated in accordance with the provisions of SFAS No. 123R. The Company recognizes equity compensation costs on a straight-line basis over the requisite service period for each award.

Stock Options Summary

At December 31, 2007, 827,500 options were awarded of which 632,783 remained outstanding. Options vest 25% on the first anniversary of the date of grant and 6.25% in each subsequent calendar quarter thereafter until fully vested. The maximum term of the options granted is ten years.

		632,783					493,943

As of December 31, 2007, the Company had $0.3 million of unrecognized compensation cost related to stock option awards. The Company anticipates this cost will be recognized over a weighted-average period of approximately 2.4 years. The Company calculates the grant date fair value of option awards using a Black-Scholes option-pricing model. Expected volatility is based on an assessment of the Company’s realized volatility as well as analysis of a peer group of comparable entities. 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. The risk-free rate is based on the U.S. Treasury rate at the time of grant for instruments of similar term.

The assumptions used in the fair value determination of stock options granted for the years ended December 31 are summarized as follows:


	2007			2006			2005
Risk-free interest rate		4.48% - 4.70	%		4.31	%		3.64% - 3.72	%
Expected volatility		21.0	%		21.0	%		15.4	%
Expected dividend yield		4.71	%		5	%		5	%
Weighted average expected life of options	5 years			5 years			5 years

The weighted average grant date fair value of the options issued in 2007, 2006 and 2005 was $4.25, $3.56 and $1.93, respectively.

Option Exercises

The total intrinsic value of options exercised was $0.2 million during 2007 and $0.8 million during both 2006 and 2005.

The Company received approximately $0.3 million, $0.8 million and $1.1 million from the exercise of stock options during 2007, 2006 and 2005, respectively. Shares issued as a result of stock option exercises are funded through the issuance of new shares. The Company recognized compensation expense associated with these awards of $0.3 million in both 2007 and 2006, and $0.1 million during 2005.

During the third quarter of 2005, certain stock option awards were deemed vested as part of a severance agreement negotiated with a former officer of the Company. Under the terms of this agreement, the vesting of 8,438 options was accelerated, resulting in additional compensation expense of approximately $0.1 million based on the intrinsic value of the accelerated awards at the date of modification. All remaining unvested stock options and restricted common share awards granted to this individual were forfeited as of the date of separation.

Non-vested share awards

The Company granted 60,171 restricted common shares to executive officers in 2005 that vest at the end of the seven-year award period, or earlier upon achieving certain defined market conditions over the term of the award. In both February and August 2006, 25% of the than outstanding 56,124 shares awarded to executive officers vested upon achievement of one of the specified market conditions. In April 2006, the Company awarded a total of 68,049 restricted common shares in two separate awards to executive officers. The first award of 30,931 shares will vest at the end of the approximately four-year award period. The second award of 37,118 shares will vest only upon the achievement of specified market conditions. In April 2007, the Company granted 68,480 restricted common shares in two separate awards to its executive officers. The first award of 34,240 shares will vest 25% per year over a four-year award term. The second award of 34,240 shares awarded will vest upon achievement of specified market conditions. The Company recognized $0.8 million, $1.1 million and $0.2 million of compensation expense associated with these share based awards in 2007, 2006 and 2005, respectively. Dividends on all restricted share awards are recorded as a reduction of shareholders’ equity. Dividends on non-vested shares are not subtracted from net income when calculating earnings per share.

Independent members of our Board of Trustees received annual grants of common shares as a component of compensation for serving on the Company’s Board of Trustees. In May 2006, the Company issued a total of 12,000 restricted common shares to all independent trustees, all of which vest ratably in quarterly increments over the twelve-month period from the award date. In May 2007, the Company issued a total of 10,500 common shares to all independent trustees, all of which will vest at the completion of a twelve-month period from the award date. The Company recognized $0.3 million, $0.2 million and $0.1 million of compensation expense associated with trustee share based awards for the years ended December 31, 2007, 2006 and 2005, respectively.

A summary of the Company’s non-vested share awards as of December 31, 2007 is as follows:


				Weighted
	Non-vested			Average Grant
	Shares			Date Fair Value
Non-vested at December 31, 2004		—		$	—

Vested		(6,000	)		26.84

Non-vested at December 31, 2007		175,091		$	23.26

As of December 31, 2007, the Company had $2.6 million of unrecognized compensation cost related to non-vested shares. The Company anticipates this cost will be recognized over a weighted-average period of 2.8 years. The Company derived the requisite service period over which the compensation expense will be recognized using a lattice model for shares vesting based on specified market conditions. The Company used the following assumptions in determining the derived service period and the fair value of its awards that vest solely on market conditions:


	2007			2006
Risk-free interest rate		4.74	%		5.28	%
Volatility		23	%		21	%
Market average return (fifty-seven years of S&P 500)		9.05	%		8.94	%
Total expected return		6.3	%		6.6	%

The weighted average grant date fair value of the non-vested share awards granted in 2007, 2006 and 2005 was $23.46, $22.97 and $26.25, respectively. The total value of shares vested was $0.2 million, $1.1 million and $0.1 million at December 31, 2007, 2006 and 2005, respectively. The Company issues new shares, subject to restrictions, upon each grant of non-vested share awards.

(b) 401(k) Plan

The Company has a 401(k) defined contribution plan covering all employees in accordance with the Internal Revenue Code. The maximum employer or employee contribution cannot exceed the IRS limits for the plan year. Employees are eligible to contribute after one year of consecutive service. The Company matches employee contributions after one year of service up to a specified percentage of a participant’s annual compensation. The Company matched employee contributions up to 6% for 2007 and 2006 and 7.5% for 2005. Employee and employer contributions vest immediately. The Company pays for administrative expenses and matching contributions with cash. The Company’s plan does not allow for the Company to make additional discretionary contributions. The Company’s contributions for the years ended December 31, 2007, 2006 and 2005 were $0.3 million, $0.2 million and $0.2 million, respectively. The employer match payable to the 401(k) plan was fully funded as of December 31, 2007.

(13) Segment Information

The Company’s reportable segments consist of three distinct reporting and operational segments within the broader Southern Mid-Atlantic geographic area in which it operates: Maryland, Northern Virginia and Southern Virginia.

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

	•		Local Market Knowledge. The Company has established relationships with local owners, the brokerage community, prospective tenants and property managers in its markets. The Company believes these relationships enhance its efforts to locate attractive acquisition opportunities and lease space in its properties.

	•		Favorable Lease Terms. As of December 31, 2007, 511 of the Company’s 796 leases (representing 71.6% of the leased space in the Company’s portfolio) were triple-net leases, under which tenants are contractually obligated to reimburse the Company for virtually all costs of occupancy, including property taxes, utilities, insurance and maintenance. In addition, the Company’s leases generally provide for revenue growth through contractual rent increases.

	•		Tenant Mix. As of December 31, 2007, the Company’s tenants included the U.S. Government (7.3% of its total annualized rental revenue), manufacturing (25.7% of its total annualized rental revenue), professional, scientific and technical services (18.3% of its total annualized rental revenue) and additional smaller tenants (48.7% of its total annualized rental revenue). The Company believes its current tenant base provides a desirable mix of stability, diversity and growth potential.
