GOVERNMENT PROPERTIES INCOME TRUST
2010 FORM 10-K ANNUAL REPORT

Table of Contents

PART I

Item 1.    Business

        The Company.    We were organized as a real estate investment trust, or REIT, under Maryland law in February, 2009 as a wholly owned subsidiary of CommonWealth REIT, or CWH. CWH is a REIT listed on the New York Stock Exchange, or the NYSE, which owns office and industrial properties with a historical cost of over $6.9 billion. We were organized to concentrate the ownership of certain CWH properties that are majority leased to government tenants and to expand such investments. In April, 2009, we acquired 100% ownership of the properties that we owned at the time of our initial public offering, or IPO, by means of a contribution from CWH to one of our subsidiaries. During 2009 and 2010, we issued an aggregate of 30,475,000 of our common shares of beneficial interest, $0.01 par value per share, or Shares, in three public offerings. CWH currently owns 24.6% of our outstanding Shares.

        As of December 31, 2010, we owned 55 properties for a total investment of approximately $1.0 billion at cost, and a depreciated book value of $846.4 million. These 55 properties have approximately 6.8 million rentable square feet.

        Our principal executive offices are located at Two Newton Place, 255 Washington Street, Suite 300, Newton, Massachusetts 02458-1634, and our telephone number is (617) 219-1440.

        Our Business Plan.    Our business plan is to maintain our properties, seek to renew our leases as they expire, selectively acquire additional properties that are majority leased to government tenants and pay distributions to our shareholders. As our current leases expire, we will attempt to renew our leases with existing tenants or to enter into leases with new tenants; in both circumstances at rents which are equal to or higher than the rents we now receive. Our ability to renew leases with our existing tenants or to enter into new leases with new tenants and the rents we are able to charge will depend in large part upon market conditions which are generally beyond our control. Nonetheless, our historical experience is that government tenants frequently renew leases to avoid the costs and disruptions that may result from relocating government operations.

        Our Growth Strategy.    Our growth strategy with regards to our current properties is to attempt to increase the rents we receive from these properties. To achieve rent increases we may invest in our properties to make improvements requested by existing tenants or to induce lease renewals or new tenant leases when our current leases expire. However, as noted above, our ability to maintain or increase the rents we receive from our current properties will depend in large part upon market conditions which are beyond our control.

        In addition to the growth strategy applicable to our current properties, we expect to acquire additional properties, generally within the United States, that are majority leased to government tenants. If the U.S. Government increases the amount of space that it leases, we believe that there will be increased opportunities for us to acquire additional properties that are majority leased to government tenants. We expect to acquire additional properties primarily for purposes of income.

        In evaluating potential investments, we consider various factors including the following:

•

the historic and projected rents received and likely to be received from the property;



•

the historic and expected operating expenses, including real estate taxes, incurred and expected to be incurred at the properties;



•

the growth, tax and regulatory environments of the market in which the property is located;



•

the quality, experience, and credit worthiness of the property's tenants;



•

occupancy, demand for similar properties in the same or nearby markets and the likelihood of tenants renewing at lease maturity;

1

---

•

the construction quality, physical condition and design of the property;



•

the estimated replacement cost of the property;



•

our cost of capital;



•

the geographic area and type of property; and



•

the pricing of comparable properties as evidenced by recent arm's length market sales.

        We believe that state and local governments lease significant amounts of office space. Additionally, we believe that budgetary pressures may cause an increased demand for leased space, as opposed to government owned space, among government tenants generally and state and local governments in particular. Also, we believe that some state and local governments are currently considering sale and leaseback arrangements for certain government owned properties because these arrangements may both raise capital and transfer maintenance obligations to private landlords, like us.

        Finally, we believe that the reduction in available capital, particularly debt capital, that resulted from the recent recession may cause acquisition opportunities to become available to us. During the height of the last economic expansion, the readily available debt capital contributed to an increase in real estate valuations. As debt capital has become less available, an increasing number of real estate owners may need to raise capital to pay their lenders. Some of these owners may seek to sell properties that are majority leased to government tenants in order to raise capital to meet their debt obligations.

        From time to time, we consider the sale of properties or investments. However, we generally consider ourselves to be a long term investor and are more interested in the long term earnings potential of our properties than selling properties for short term gains. We make disposition decisions based on a number of factors including, but not limited to, the following:

•

the proposed sale price;



•

the strategic fit of the property or investment with the rest of our portfolio; and



•

the existence of alternative sources, uses or needs for capital.

        Our Board of Trustees may change our investment policies at any time without a vote of our shareholders. Although we have no current intention to do so, we could in the future adopt policies with respect to investments in real estate mortgages or securities of other persons, including persons engaged in real estate activities.

        Financing Policies.    To qualify for taxation as a REIT under the Internal Revenue Code of 1986, as amended, or the IRC, we must distribute at least 90% of our annual REIT taxable income and satisfy a number of organizational and operational requirements. Accordingly, we generally will not be able to retain sufficient cash from operations to repay debts, invest in properties or fund acquisitions. Instead, we expect to repay our debts, invest in our properties and fund acquisitions by borrowing and issuing equity securities. After our IPO, our growth was initially financed by borrowings under a $250 million secured revolving credit facility. We replaced our secured revolving credit facility in October 2010 with a $500 million unsecured revolving credit facility, or our unsecured revolving credit facility. As we utilize our unsecured revolving credit facility, we expect to refinance, or reduce amounts outstanding under, this facility with term debt or equity issuances. We will decide when and whether to issue new debt or equity depending upon market conditions. Because our ability to raise capital may depend, in large part, upon market conditions, we can provide you no assurance that we will be able to raise sufficient capital to repay our debt or to fund our growth strategy.

        We have not engaged in underwriting securities of other issuers and do not intend to do so. We have not in the past, but we may in the future, invest in the securities of other issuers for the purpose

2

---

of exercising control, issue senior securities, make loans to other persons, engage in the sale of investments, offer securities in exchange for property or repurchase or reacquire our securities.

        Our current borrowing policy, established by our Board of Trustees, is to limit our debt to no more than 50% of the undepreciated book value of our properties. The borrowing limitations established by the covenants in our unsecured revolving credit facility prohibit us from maintaining a debt to total asset value, as defined, of greater than 60%. We may from time to time reevaluate and modify our financing policies in light of then current market conditions, relative availability and costs of debt and equity capital, market values of properties, growth and acquisition opportunities and other factors, and we may increase or decrease our ratio of debt to total capitalization accordingly. Our Board of Trustees may change our financing policies at any time without a vote of our shareholders.

        Manager.    Our day to day operations are conducted by Reit Management & Research LLC, or RMR. RMR originates and presents investment and divestment opportunities to our Board of Trustees and provides management and administrative services to us. RMR is a Delaware limited liability company beneficially owned by Barry M. Portnoy and Adam D. Portnoy, our Managing Trustees. RMR has a principal place of business at Two Newton Place, 255 Washington Street, Suite 300, Newton Massachusetts, 02458-1634, and its telephone number is (617) 332-3990. RMR also acts as the manager to CWH, Hospitality Properties Trust, or HPT, and Senior Housing Properties Trust, or SNH, and provides management services to other private and public companies, including Five Star Quality Care, Inc., or FVE, and TravelCenters of America LLC, or TA. Barry M. Portnoy is the Chairman of RMR, and its other directors are Adam D. Portnoy, Gerard M. Martin and David J. Hegarty. The executive officers of RMR are: Adam D. Portnoy, President and Chief Executive Officer; Jennifer B. Clark, Executive Vice President and General Counsel; David J. Hegarty, Executive Vice President and Secretary; Mark L. Kleifges, Executive Vice President; John A. Mannix, Executive Vice President; John G. Murray, Executive Vice President; Thomas M. O'Brien, Executive Vice President; John C. Popeo, Executive Vice President, Treasurer and Chief Financial Officer; David M. Blackman, Senior Vice President; Ethan S. Bornstein, Senior Vice President; Richard A. Doyle, Senior Vice President; Paul Hoagland, Senior Vice President; David M. Lepore, Senior Vice President; Bruce J. Mackey, Jr., Senior Vice President; and Andrew J. Rebholz, Senior Vice President. Adam D. Portnoy, David M. Blackman and Mark L. Kleifges were or are also our executive officers. Adam D. Portnoy was our President from the time of our IPO until he resigned in January 2011. David M. Blackman was our Treasurer and Chief Financial Officer from the time of our IPO until he was elected our President and Chief Operating Officer in January 2011. Mark L. Kleifges replaced Mr. Blackman as Treasurer and Chief Financial Officer. Mr. Adam Portnoy, Mr. Kleifges and other executive officers of RMR also serve as officers of other companies to which RMR provides management services.

        Employees.    We have no employees. Services which would otherwise be provided by employees are provided by RMR and by our Managing Trustees and officers. As of February 1, 2011, RMR had approximately 650 full time employees in its headquarters and regional offices located throughout the United States.

        Competition.    Investing in and operating office buildings and maintaining relationships with government tenants and attracting new government tenants is a very competitive business. We compete against other REITs, numerous financial institutions, individuals and public and private companies who are actively engaged in this business. Also, we compete for investments based on a number of factors including purchase prices, closing terms, underwriting criteria and our reputation. Our ability to successfully compete is also materially impacted by the availability and cost of capital to us. We do not believe we have a dominant position in any of the geographic markets in which we operate, but some of our competitors are dominant in selected markets. Many of our competitors have greater financial resources than we have. We believe we have some competitive advantages in leasing to government tenants and purchasing government leased properties because of our experience and familiarity with

3

---

government leasing procedures. We also believe the experience and abilities of our management and the quality of our properties may afford us some competitive advantages and allow us to operate our business successfully despite the competitive nature of our business.

        For additional information about competition and other risks associated with our business, please see "Risk Factors" of this Annual Report on Form 10-K.

        Environmental and Climate Change Matters.    Under various laws, owners as well as tenants and operators of real estate may be required to investigate and clean up or remove hazardous substances present at or migrating from properties they own, lease or operate and may be held liable for property damage or personal injuries that result from hazardous substances. These laws also expose us to the possibility that we may become liable to reimburse governments for damages and costs they incur in connection with hazardous substances. Since our formation, it has been our practice to obtain and review "Phase I" environmental surveys prior to the acquisition of properties in order to assess the possible presence of and cost of removing hazardous substances. Certain of our buildings contain asbestos. We believe any asbestos in our buildings is contained in accordance with current regulations, and we have no current plans to remove it. If we remove the asbestos or renovate or demolish these properties, certain environmental regulations govern the manner in which the asbestos must be handled and removed. We do not believe that there are environmental conditions at any of our properties that have had or will have a material adverse effect on us. However, no assurances can be given that conditions are not present at our properties or that costs we may be required to incur in the future to remediate contamination will not have a material adverse effect on our business or financial condition. For more information, see "Risk Factors—Risks Related to Our Business—Real estate ownership creates risks and liabilities."

        In recent years, in reaction to the Energy Policy Act of 2005, the U.S. Government has instituted "green lease" policies which include the "Promotion of Energy Efficiency and Use of Renewable Energy" as one of the factors it considers when leasing property. In reaction to these new policies, we have engaged an energy consultant to monitor and help improve energy use at our properties.

        In accord with the U.S. Government's general policy of preferring energy efficient buildings, the Energy Independence and Security Act of 2007 allows the General Services Administration, or GSA, to prefer buildings for lease that have received an "Energy Star" label. Buildings that reach a specified level of energy efficiency may receive this label. We have received ratings for many of our buildings, and 25 of them have qualified for Energy Star labels. We and RMR became participants in the Energy Star program in July 2008, and we are studying ways to improve the energy efficiency at all of our buildings and determining if we can obtain Energy Star labels for our buildings, which do not yet have them, at a reasonable cost. We do not yet know whether it will be possible to obtain Energy Star labels for all our properties, and we have not yet determined whether it will make economic sense to do so.

        The U.S. Government's "green lease" initiative also permits government tenants to require LEED®-CI certification in selecting new premises or renewing leases at existing premises. Obtaining such certification may be costly and time consuming. If we commit to a government tenant that we will obtain such certification in order to attract or retain such government tenant, our failure to receive such certification could result in the government tenant implementing corrective action, including deducting the costs of actions required for certification from its rent due to us. For more information, see "Risk Factors—Risks Related to Our Business—The U.S. Government's "green lease" policies may adversely affect us."

        Current political debate about climate change has resulted in various existing and proposed treaties, laws and regulations which are intended to limit carbon emissions. We believe such treaties, laws and regulations being enacted or proposed may cause energy costs at our properties to increase, but we do not expect the direct impact of these increases to be material to our results of operations because the increased costs either would be the responsibility of our tenants directly or in large part

4

---

may be passed through by us to our tenants as additional lease payments. Although we do not believe it is likely in the foreseeable future, laws enacted to mitigate climate change may make some of our buildings obsolete or cause us to make material investments in our properties which could materially and adversely affect our financial condition and results of operations.

FEDERAL INCOME TAX CONSIDERATIONS

        The following summary of federal income tax considerations is based on existing law, and is limited to investors who own our shares as investment assets rather than as inventory or as property used in a trade or business. The summary does not discuss all of the particular tax consequences that might be relevant to you if you are subject to special rules under federal income tax law, for example if you are:

•

a bank, life insurance company, regulated investment company, or other financial institution;



•

a broker, dealer or trader in securities or foreign currency;



•

a person who has a functional currency other than the U.S. dollar;



•

a person who acquires our shares in connection with employment or other performance of services;



•

a person subject to alternative minimum tax;



•

a person who owns our shares as part of a straddle, hedging transaction, constructive sale transaction, constructive ownership transaction, or conversion transaction; or



•

except as specifically described in the following summary, a tax-exempt entity or a foreign person.

        The IRC sections that govern federal income tax qualification and treatment of a REIT and its shareholders are complex. This presentation is a summary of applicable IRC provisions, related rules and regulations and administrative and judicial interpretations, all of which are subject to change, possibly with retroactive effect. Future legislative, judicial, or administrative actions or decisions could also affect the accuracy of statements made in this summary. We have not received a ruling from the Internal Revenue Service, or the IRS, with respect to any matter described in this summary, and we cannot assure you that the IRS or a court will agree with the statements made in this summary. The IRS or a court could, for example, take a different position from that described in this summary with respect to our acquisitions, operations, restructurings or other matters, which, if successful, could result in significant tax liabilities for applicable parties. In addition, this summary is not exhaustive of all possible tax consequences, and does not discuss any estate, gift, state, local, or foreign tax consequences. For all these reasons, we urge you and any prospective acquiror of our shares to consult with a tax advisor about the federal income tax and other tax consequences of the acquisition, ownership and disposition of our shares. Our intentions and beliefs described in this summary are based upon our understanding of applicable laws and regulations that are in effect as of the date of this Annual Report on Form 10-K. If new laws or regulations are enacted which impact us directly or indirectly, we may change our intentions or beliefs.

        Your federal income tax consequences may differ depending on whether or not you are a "U.S. shareholder." For purposes of this summary, a "U.S. shareholder" is:

•

a citizen or resident of the United States, including an alien individual who is a lawful permanent resident of the United States or meets the substantial presence residency test under the federal income tax laws;



•

an entity treated as a corporation for federal income tax purposes that is created or organized in or under the laws of the United States, any state thereof or the District of Columbia;



•

an estate the income of which is subject to federal income taxation regardless of its source; or



•

a trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control

6

---

all substantial decisions of the trust, or an electing trust in existence on August 20, 1996, to the extent provided in Treasury regulations;

whose status as a U.S. shareholder is not overridden by an applicable tax treaty. Conversely, a "non-U.S. shareholder" is a beneficial owner of our shares who is not a U.S. shareholder. If a partnership (including any entity treated as a partnership for federal income tax purposes) is a beneficial owner of our shares, the tax treatment of a partner in the partnership generally will depend upon the status of the partner and the activities of the partnership. A beneficial owner that is a partnership and partners in such a partnership should consult their tax advisors about the federal income tax consequences of the acquisition, ownership and disposition of our shares.

Taxation as a REIT

        For periods ending on or before the date we ceased to be wholly owned by CWH, each of us and any of our then existing subsidiaries was at all times either a qualified REIT subsidiary of CWH within the meaning of Section 856(i) of the IRC or a noncorporate entity that for federal income tax purposes was not treated as separate from CWH under regulations issued under Section 7701 of the IRC. During such periods, we and any of our then existing subsidiaries were not taxpayers separate from CWH for federal income tax purposes. For those periods, CWH remains, pursuant to the transaction agreement we entered into with CWH at the time of our IPO, or the transaction agreement, solely responsible for the federal income tax with respect to our assets, liabilities and items of income, deduction and credit as well as the federal income tax filings in respect of our and any of our then existing subsidiaries' operations. Our initial taxable year commenced upon our ceasing to be wholly owned by CWH.

        We have elected to be taxed as a REIT under Sections 856 through 860 of the IRC commencing with our taxable year ending December 31, 2009. Our REIT election, assuming continuing compliance with the then applicable qualification tests, continues in effect for subsequent taxable years. Although no assurance can be given, we believe that we have been organized and have operated, and will continue to be organized and to operate, in a manner that qualified and will continue to qualify us to be taxed under the IRC as a REIT.

        As a REIT, we generally are not subject to federal income tax on our net income distributed as dividends to our shareholders. Distributions to our shareholders generally are included in their income as dividends to the extent of our current or accumulated earnings and profits. Our dividends are not generally entitled to the favorable 15% rate on qualified dividend income (scheduled to increase to ordinary income rates for taxable years beginning after December 31, 2012), but a portion of our dividends may be treated as capital gain dividends, all as explained below. No portion of any of our dividends is eligible for the dividends received deduction for corporate shareholders. Distributions in excess of current or accumulated earnings and profits generally are treated for federal income tax purposes as return of capital to the extent of a recipient shareholder's basis in our shares, and will reduce this basis. Our current or accumulated earnings and profits are generally allocated first to distributions made on our preferred shares, if any, and thereafter to distributions made on our common shares. For all these purposes, our distributions include both cash distributions and any in kind distributions of property that we might make.

        Our counsel, Sullivan & Worcester LLP, has opined that we have been organized and have qualified as a REIT under the IRC for our 2009 through 2010 taxable years, and that our current investments and plan of operation enable us to continue to meet the requirements for qualification and taxation as a REIT under the IRC. Our continued qualification and taxation as a REIT will depend upon our compliance with various qualification tests imposed under the IRC and summarized below. While we believe that we will satisfy these tests, our counsel does not review compliance with these tests on a continuing basis. If we fail to qualify as a REIT, we will be subject to federal income taxation

7

---

as if we were a C corporation and our shareholders will be taxed like shareholders of C corporations. In this event, we could be subject to significant tax liabilities, and the amount of cash available for distribution to our shareholders could be reduced or eliminated.

        If we qualify as a REIT and meet the tests described below, we generally will not pay federal income tax on amounts we distribute to our shareholders. However, even if we qualify as a REIT, we may be subject to federal tax in the following circumstances:

•

We will be taxed at regular corporate rates on any undistributed "real estate investment trust taxable income," including our undistributed net capital gains.



•

If our alternative minimum taxable income exceeds our taxable income, we may be subject to the corporate alternative minimum tax on our items of tax preference.



•

If we have net income from the disposition of "foreclosure property" that is held primarily for sale to customers in the ordinary course of business or from other nonqualifying income from foreclosure property, we will be subject to tax on this income at the highest regular corporate rate, currently 35%.



•

If we have net income from prohibited transactions, including dispositions of inventory or property held primarily for sale to customers in the ordinary course of business other than foreclosure property, we will be subject to tax on this income at a 100% rate.



•

If we fail to satisfy the 75% gross income test or the 95% gross income test discussed below, but nonetheless maintain our qualification as a REIT, we will be subject to tax at a 100% rate on the greater of the amount by which we fail the 75% or the 95% test, with adjustments, multiplied by a fraction intended to reflect our profitability.



•

If we fail to distribute for any calendar year at least the sum of 85% of our REIT ordinary income for that year, 95% of our REIT capital gain net income for that year, and any undistributed taxable income from prior periods, we will be subject to a 4% nondeductible excise tax on the excess of the required distribution over the amounts actually distributed.



•

If we acquire an asset from a corporation in a transaction in which our basis in the asset is determined by reference to the basis of the asset in the hands of a present or former C corporation, and if we subsequently recognize gain on the disposition of this asset during a specified period (generally, ten years) beginning on the date on which the asset ceased to be owned by the C corporation, then we will pay tax at the highest regular corporate tax rate, which is currently 35%, on the lesser of the excess of the fair market value of the asset over the C corporation's basis in the asset on the date the asset ceased to be owned by the C corporation, or the gain we recognize in the disposition.



•

If we acquire a corporation, to preserve our status as a REIT we must generally distribute all of the C corporation earnings and profits inherited in that acquisition, if any, not later than the end of the taxable year of the acquisition. However, if we fail to do so, relief provisions would allow us to maintain our status as a REIT provided we distribute any subsequently discovered C corporation earnings and profits and pay an interest charge in respect of the period of delayed distribution.



•

As summarized below, REITs are permitted within limits to own stock and securities of a "taxable REIT subsidiary." A taxable REIT subsidiary is separately taxed on its net income as a C corporation, and is subject to limitations on the deductibility of interest expense paid to its REIT parent. In addition, its REIT parent is subject to a 100% tax on the difference between amounts charged and redetermined rents and deductions, including excess interest.

•

If and to the extent we invest in properties in foreign jurisdictions, our income from those properties will generally be subject to tax in those jurisdictions. If we continue to operate as we do, then we will distribute our taxable income to our shareholders each year and we will generally not pay federal income tax. As a result, we cannot recover the cost of foreign income taxes imposed on our foreign investments by claiming foreign tax credits against our federal income tax liability. Also, we cannot pass through to our shareholders any foreign tax credits.

        If we fail to qualify or elect not to qualify as a REIT, we will be subject to federal income tax in the same manner as a C corporation. Distributions to our shareholders if we do not qualify as a REIT will not be deductible by us nor will distributions be required under the IRC. In that event, distributions to our shareholders will generally be taxable as ordinary dividends potentially eligible for the 15% income tax rate (scheduled to increase to ordinary income rates for taxable years beginning after December 31, 2012) discussed below in "Taxation of U.S. Shareholders" and, subject to limitations in the IRC, will be eligible for the dividends received deduction for corporate shareholders. Also, we will generally be disqualified from qualification as a REIT for the four taxable years following disqualification. If we do not qualify as a REIT for even one year, this could result in reduction or elimination of distributions to our shareholders, or in our incurring substantial indebtedness or liquidating substantial investments in order to pay the resulting corporate-level taxes. The IRC provides certain relief provisions under which we might avoid automatically ceasing to be a REIT for failure to meet certain REIT requirements, all as discussed in more detail below.

REIT Qualification Requirements

        General Requirements.    Section 856(a) of the IRC defines a REIT as a corporation, trust or association:

(1)

that is managed by one or more trustees or directors;



(2)

the beneficial ownership of which is evidenced by transferable shares or by transferable certificates of beneficial interest;



(3)

that would be taxable, but for Sections 856 through 859 of the IRC, as a C corporation;



(4)

that is not a financial institution or an insurance company subject to special provisions of the IRC;



(5)

the beneficial ownership of which is held by 100 or more persons;



(6)

that is not "closely held" as defined under the personal holding company stock ownership test, as described below; and



(7)

that meets other tests regarding income, assets and distributions, all as described below.

Section 856(b) of the IRC provides that conditions (1) through (4) must be met during the entire taxable year and that condition (5) must be met during at least 335 days of a taxable year of 12 months, or during a pro rata part of a taxable year of less than 12 months. Section 856(h)(2) of the IRC provides that neither condition (5) nor (6) need be met for our first taxable year as a REIT. We believe that we have met conditions (1) through (7) during each of the requisite periods ending on or before the close of our most recently completed taxable year, and that we can continue to meet these conditions in future taxable years. There can, however, be no assurance in this regard.

        By reason of condition (6), we will fail to qualify as a REIT for a taxable year if at any time during the last half of a year more than 50% in value of our outstanding shares is owned directly or indirectly by five or fewer individuals. To help comply with condition (6), our Declaration of Trust restricts transfers of our shares. In addition, if we comply with applicable Treasury regulations to ascertain the ownership of our shares and do not know, or by exercising reasonable diligence would not

9

---

have known, that we failed condition (6), then we will be treated as having met condition (6). However, our failure to comply with these regulations for ascertaining ownership may result in a penalty of $25,000, or $50,000 for intentional violations. Accordingly, we have complied and will continue to comply with these regulations, including requesting annually from record holders of significant percentages of our shares information regarding the ownership of our shares. Under our Declaration of Trust, our shareholders are required to respond to these requests for information.

        For purposes of condition (6), the term "individuals" is defined in the IRC to include natural persons, supplemental unemployment compensation benefit plans, private foundations and portions of a trust permanently set aside or used exclusively for charitable purposes, but not other entities or qualified pension plans or profit-sharing trusts. As a result, REIT shares owned by an entity that is not an "individual" are considered to be owned by the direct and indirect owners of the entity that are individuals (as so defined), rather than to be owned by the entity itself. Similarly, REIT shares held by a qualified pension plan or profit-sharing trust are treated as held directly by the individual beneficiaries in proportion to their actuarial interests in such plan or trust. Consequently, five or fewer such trusts could own more than 50% of the interests in an entity without jeopardizing that entity's federal income tax qualification as a REIT. However, as discussed below, if a REIT is a "pension-held REIT," each qualified pension plan or profit-sharing pension trust owning more than 10% of the REIT's shares by value generally may be taxed on a portion of the dividends it receives from the REIT.

        The IRC provides that we will not automatically fail to be a REIT if we do not meet conditions (1) through (6), provided we can establish reasonable cause for any such failure. Each such excused failure will result in the imposition of a $50,000 penalty instead of REIT disqualification. It is impossible to state whether in all circumstances we would be entitled to the benefit of this relief provision. This relief provision applies to any failure of the applicable conditions, even if the failure first occurred in a prior taxable year.

        Our Wholly-Owned Subsidiaries and Our Investments through Partnerships.    Except in respect of taxable REIT subsidiaries as discussed below, Section 856(i) of the IRC provides that any corporation, 100% of whose stock is held by a REIT and its disregarded subsidiaries, is a qualified REIT subsidiary and shall not be treated as a separate corporation. The assets, liabilities and items of income, deduction and credit of a qualified REIT subsidiary are treated as the REIT's. We believe that each of our direct and indirect wholly-owned subsidiaries, other than the taxable REIT subsidiaries discussed below, will be either a qualified REIT subsidiary within the meaning of Section 856(i) of the IRC, or a noncorporate entity that for federal income tax purposes is not treated as separate from its owner under regulations issued under Section 7701 of the IRC. Thus, except for the taxable REIT subsidiaries discussed below, in applying all the federal income tax REIT qualification requirements described in this summary, all assets, liabilities and items of income, deduction and credit of our direct and indirect wholly-owned subsidiaries are treated as ours.

        We may invest in real estate through one or more limited or general partnerships or limited liability companies that are treated as partnerships for federal income tax purposes. In the case of a REIT that is a partner in a partnership, regulations under the IRC provide that, for purposes of the REIT qualification requirements regarding income and assets discussed below, the REIT is deemed to own its proportionate share of the assets of the partnership corresponding to the REIT's proportionate capital interest in the partnership and is deemed to be entitled to the income of the partnership attributable to this proportionate share. In addition, for these purposes, the character of the assets and gross income of the partnership generally retain the same character in the hands of the REIT. Accordingly, our proportionate share of the assets, liabilities, and items of income of each partnership in which we become a partner is treated as ours for purposes of the income tests and asset tests discussed below. In contrast, for purposes of the distribution requirement discussed below, we would take into account as a partner our share of the partnership's income as determined under the general federal income tax rules governing partners and partnerships under Sections 701 through 777 of the IRC.

        Taxable REIT Subsidiaries.    We are permitted to own any or all of the securities of a "taxable REIT subsidiary" as defined in Section 856(l) of the IRC, provided that no more than 25% of our assets, at the close of each quarter, is comprised of our investments in the stock or securities of our taxable REIT subsidiaries. Among other requirements, a taxable REIT subsidiary must:

        (1)   be a non-REIT corporation for federal income tax purposes in which we directly or indirectly own shares;

        (2)   join with us in making a taxable REIT subsidiary election;

        (3)   not directly or indirectly operate or manage a lodging facility or a health care facility; and

        (4)   not directly or indirectly provide to any person, under a franchise, license, or otherwise, rights to any brand name under which any lodging facility or health care facility is operated, except that in limited circumstances a subfranchise, sublicense or similar right can be granted to an independent contractor to operate or manage a lodging facility or a health care facility.

        In addition, a corporation other than a REIT in which a taxable REIT subsidiary directly or indirectly owns more than 35% of the voting power or value will automatically be treated as a taxable REIT subsidiary. Subject to the discussion below, we believe that we and each of our taxable REIT subsidiaries have complied with, and will continue to comply with, the requirements for taxable REIT subsidiary status at all times during which we intend for the subsidiary's taxable REIT subsidiary election to be in effect, and we believe that the same will be true for any taxable REIT subsidiary that we later form or acquire.

        Our ownership of stock and securities in taxable REIT subsidiaries is exempt from the 10% and 5% REIT asset tests discussed below. Also, as discussed below, taxable REIT subsidiaries can perform services for our tenants without disqualifying the rents we receive from those tenants under the 75% or 95% gross income tests discussed below. Moreover, because taxable REIT subsidiaries are taxed as C corporations that are separate from us, their assets, liabilities and items of income, deduction and credit generally are not imputed to us for purposes of the REIT qualification requirements described in this summary. Therefore, taxable REIT subsidiaries can generally undertake third-party management and development activities and activities not related to real estate.

        Restrictions are imposed on taxable REIT subsidiaries to ensure that they will be subject to an appropriate level of federal income taxation. For example, a taxable REIT subsidiary may not deduct interest paid in any year to an affiliated REIT to the extent that the interest payments exceed, generally, 50% of the taxable REIT subsidiary's adjusted taxable income for that year. However, the taxable REIT subsidiary may carry forward the disallowed interest expense to a succeeding year, and deduct the interest in that later year subject to that year's 50% adjusted taxable income limitation. In addition, if a taxable REIT subsidiary pays interest, rent, or other amounts to its affiliated REIT in an amount that exceeds what an unrelated third party would have paid in an arm's length transaction, then the REIT generally will be subject to an excise tax equal to 100% of the excessive portion of the payment. Finally, if in comparison to an arm's length transaction, a tenant has overpaid rent to the REIT in exchange for underpaying the taxable REIT subsidiary for services rendered, then the REIT may be subject to an excise tax equal to 100% of the overpayment. There can be no assurance that arrangements involving our taxable REIT subsidiaries will not result in the imposition of one or more of these deduction limitations or excise taxes, but we do not believe that we are or will be subject to these impositions.

        Income Tests.    There are two gross income requirements for qualification as a REIT under the IRC:

•

At least 75% of our gross income (excluding: (a) gross income from sales or other dispositions of property held primarily for sale; (b) any income arising from "clearly identified" hedging

11

---

transactions that we enter into to manage interest rate or price fluctuations with respect to borrowings we incur to acquire or carry real estate assets; (c) any income arising from "clearly identified" hedging transactions that we enter into primarily to manage risk of currency fluctuations relating to any item that qualifies under the 75% or 95% gross income tests; (d) real estate foreign exchange gain (as defined in Section 856(n)(2) of the IRC); and (e) income from the repurchase or discharge of indebtedness) must be derived from investments relating to real property, including "rents from real property" as defined under Section 856 of the IRC, interest and gain from mortgages on real property, income and gain from foreclosure property, or dividends and gain from shares in other REITs. When we receive new capital in exchange for our shares or in a public offering of five-year or longer debt instruments, income attributable to the temporary investment of this new capital in stock or a debt instrument, if received or accrued within one year of our receipt of the new capital, is generally also qualifying income under the 75% gross income test.

•

At least 95% of our gross income (excluding: (a) gross income from sales or other dispositions of property held primarily for sale; (b) any income arising from "clearly identified" hedging transactions that we enter into to manage interest rate or price fluctuations with respect to borrowings we incur to acquire or carry real estate assets; (c) any income arising from "clearly identified" hedging transactions that we enter into primarily to manage risk of currency fluctuations relating to any item that qualifies under the 75% or 95% gross income tests; (d) passive foreign exchange gain (as defined in Section 856(n)(3) of the IRC); and (e) income from the repurchase or discharge of indebtedness) must be derived from a combination of items of real property income that satisfy the 75% gross income test described above, dividends, interest, or gains from the sale or disposition of stock, securities, or real property.

For purposes of the 75% and 95% gross income tests outlined above, income derived from a "shared appreciation provision" in a mortgage loan is generally treated as gain recognized on the sale of the property to which it relates. Although we will use our best efforts to ensure that the income generated by our investments will be of a type that satisfies both the 75% and 95% gross income tests, there can be no assurance in this regard.

        In order to qualify as "rents from real property" under Section 856 of the IRC, several requirements must be met:

•

The amount of rent received generally must not be based on the income or profits of any person, but may be based on receipts or sales.



•

Rents do not qualify if the REIT owns 10% or more by vote or value of the tenant, whether directly or after application of attribution rules. While we intend not to lease property to any party if rents from that property would not qualify as rents from real property, application of the 10% ownership rule is dependent upon complex attribution rules and circumstances that may be beyond our control. For example, an unaffiliated third party's ownership directly or by attribution of 10% or more by value of our shares, as well as an ownership position in the stock of one of our tenants which, when added to our own ownership position in that tenant, totals 10% or more by vote or value of the stock of that tenant, would result in that tenant's rents not qualifying as rents from real property. Our declaration of trust disallows transfers or purported acquisitions, directly or by attribution, of our shares to the extent necessary to maintain our REIT status under the IRC. Similarly, for the purpose of CWH retaining its own REIT status under the IRC, CWH's organizational documents contain similar provisions to limit concentrated ownership of beneficial positions in CWH. Furthermore, for as long as CWH owns more than 9.8% of our outstanding shares, we and CWH have agreed to limit ownership in any of our tenants to no more than 4.9% by each party, so that our combined ownership will remain under 10%, and we have also agreed to take reasonable actions to facilitate the REIT status under the

12

---

IRC of the other. Nevertheless, there can be no assurance that these provisions in our and CWH's organizational documents and in the transaction agreement with CWH will be effective to prevent our REIT status from being jeopardized under the 10% affiliated tenant rule. Furthermore, there can be no assurance that we will be able to monitor and enforce these restrictions, nor will our shareholders necessarily be aware of ownership of shares attributed to them under the IRC's attribution rules.

•

There is a limited exception to the above prohibition on earning "rents from real property" from a 10% affiliated tenant, if the tenant is a taxable REIT subsidiary. If at least 90% of the leased space of a property is leased to tenants other than taxable REIT subsidiaries and 10% affiliated tenants, and if the taxable REIT subsidiary's rent for space at that property is substantially comparable to the rents paid by nonaffiliated tenants for comparable space at the property, then otherwise qualifying rents paid by the taxable REIT subsidiary to the REIT will not be disqualified on account of the rule prohibiting 10% affiliated tenants.



•

In order for rents to qualify, we generally must not manage the property or furnish or render services to the tenants of the property, except through an independent contractor from whom we derive no income or through one of our taxable REIT subsidiaries. There is an exception to this rule permitting a REIT to perform customary tenant services of the sort that a tax-exempt organization could perform without being considered in receipt of "unrelated business taxable income" as defined in Section 512(b)(3) of the IRC. In addition, a de minimis amount of noncustomary services will not disqualify income as "rents from real property" so long as the value of the impermissible services does not exceed 1% of the gross income from the property.



•

If rent attributable to personal property leased in connection with a lease of real property is 15% or less of the total rent received under the lease, then the rent attributable to personal property will qualify as "rents from real property"; if this 15% threshold is exceeded, the rent attributable to personal property will not so qualify. The portion of rental income treated as attributable to personal property is determined according to the ratio of the fair market value of the personal property to the total fair market value of the real and personal property that is rented.

We believe that all or substantially all our rents have qualified and will qualify as rents from real property for purposes of Section 856 of the IRC.

        In order to qualify as mortgage interest on real property for purposes of the 75% test, interest must derive from a mortgage loan secured by real property with a fair market value, at the time the loan is made, at least equal to the amount of the loan. If the amount of the loan exceeds the fair market value of the real property, the interest will be treated as interest on a mortgage loan in a ratio equal to the ratio of the fair market value of the real property to the total amount of the mortgage loan.

        Absent the "foreclosure property" rules of Section 856(e) of the IRC, a REIT's receipt of business operating income from a property would not qualify under the 75% and 95% gross income tests. But as foreclosure property, gross income from such a business operation would so qualify. In the case of property leased by a REIT to a tenant, foreclosure property is defined under applicable Treasury regulations to include generally the real property and incidental personal property that the REIT reduces to possession upon a default or imminent default under the lease by the tenant, and as to which a foreclosure property election is made by attaching an appropriate statement to the REIT's federal income tax return. Any gain that a REIT recognizes on the sale of foreclosure property held as inventory or primarily for sale to customers, plus any income it receives from foreclosure property that would not qualify under the 75% gross income test in the absence of foreclosure property treatment, reduced by expenses directly connected with the production of those items of income, would be subject to income tax at the maximum corporate rate, currently 35%, under the foreclosure property income

13

---

tax rules of Section 857(b)(4) of the IRC. Thus, if a REIT should lease foreclosure property in exchange for rent that qualifies as "rents from real property" as described above, then that rental income is not subject to the foreclosure property income tax.

        Other than sales of foreclosure property, any gain we realize on the sale of property held as inventory or other property held primarily for sale to customers in the ordinary course of business will be treated as income from a prohibited transaction that is subject to a penalty tax at a 100% rate. This prohibited transaction income also may adversely affect our ability to satisfy the 75% and 95% gross income tests for federal income tax qualification as a REIT. We cannot provide assurances as to whether or not the IRS might successfully assert that one or more of our dispositions would be subject to the 100% penalty tax. However, we believe that dispositions of assets that we might make will not be subject to the 100% penalty tax, because we intend to:

•

own our assets for investment with a view to long-term income production and capital appreciation;



•

engage in the business of developing, owning and managing our existing properties and acquiring, developing, owning and managing new properties; and



•

make occasional dispositions of our assets consistent with our long-term investment objectives.

        If we fail to satisfy one or both of the 75% or the 95% gross income tests in any taxable year, we may nevertheless qualify as a REIT for that year if we satisfy the following requirements:

•

our failure to meet the test is due to reasonable cause and not due to willful neglect, and



•

after we identify the failure, we file a schedule describing each item of our gross income included in the 75% or 95% gross income tests for that taxable year.

It is impossible to state whether in all circumstances we would be entitled to the benefit of this relief provision for the 75% and 95% gross income tests. Even if this relief provision does apply, a 100% tax is imposed upon the greater of the amount by which we failed the 75% test or the 95% test, with adjustments, multiplied by a fraction intended to reflect our profitability. This relief provision applies to any failure of the applicable income tests, even if the failure first occurred in a prior taxable year.

        Asset Tests.    At the close of each quarter of each taxable year, we must also satisfy the following asset percentage tests in order to qualify as a REIT for federal income tax purposes:

•

At least 75% of our total assets must consist of real estate assets, cash and cash items, shares in other REITs, government securities, and temporary investments of new capital (that is, stock or debt instruments purchased with proceeds of a stock offering or a public offering of our debt with a term of at least five years, but only for the one-year period commencing with our receipt of the offering proceeds).



•

Not more than 25% of our total assets may be represented by securities other than those securities that count favorably toward the preceding 75% asset test.



•

Of the investments included in the preceding 25% asset class, the value of any one non-REIT issuer's securities that we own may not exceed 5% of the value of our total assets. In addition, we may not own more than 10% of the vote or value of any one non-REIT issuer's outstanding securities, unless that issuer is our taxable REIT subsidiary or the securities are "straight debt" securities or otherwise excepted as discussed below.



•

Our stock and securities in a taxable REIT subsidiary are exempted from the preceding 10% and 5% asset tests. However, no more than 25% of our total assets may be represented by stock or securities of taxable REIT subsidiaries.

14

---

        When a failure to satisfy the above asset tests results from an acquisition of securities or other property during a quarter, the failure can be cured by disposition of sufficient nonqualifying assets within 30 days after the close of that quarter.

        In addition, if we fail the 5% value test or the 10% vote or value tests at the close of any quarter and do not cure such failure within 30 days after the close of that quarter, that failure will nevertheless be excused if (a) the failure is de minimis and (b) within 6 months after the last day of the quarter in which we identify the failure, we either dispose of the assets causing the failure or otherwise satisfy the 5% value and 10% vote and value asset tests. For purposes of this relief provision, the failure will be "de minimis" if the value of the assets causing the failure does not exceed the lesser of (a) 1% of the total value of our assets at the end of the relevant quarter or (b) $10,000,000. If our failure is not de minimis, or if any of the other REIT asset tests have been violated, we may nevertheless qualify as a REIT if (a) we provide the IRS with a description of each asset causing the failure, (b) the failure was due to reasonable cause and not willful neglect, (c) we pay a tax equal to the greater of (1) $50,000 or (2) the highest rate of corporate tax imposed (currently 35%) on the net income generated by the assets causing the failure during the period of the failure, and (d) within 6 months after the last day of the quarter in which we identify the failure, we either dispose of the assets causing the failure or otherwise satisfy all of the REIT asset tests. These relief provisions apply to any failure of the applicable asset tests, even if the failure first occurred in a prior taxable year.

        The IRC also provides an excepted securities safe harbor to the 10% value test that includes among other items (a) "straight debt" securities, (b) certain rental agreements in which payment is to be made in subsequent years, (c) any obligation to pay rents from real property, (d) securities issued by governmental entities that are not dependent in whole or in part on the profits of or payments from a nongovernmental entity, and (e) any security issued by another REIT.

        We have maintained and will continue to maintain records of the value of our assets to document our compliance with the above asset tests, and intend to take actions as may be required to cure any failure to satisfy the tests within 30 days after the close of any quarter.

        Annual Distribution Requirements.    In order to qualify for taxation as a REIT under the IRC, we are required to make annual distributions other than capital gain dividends to our shareholders in an amount at least equal to the excess of:

        (A)  the sum of 90% of our "real estate investment trust taxable income," as defined in Section 857 of the IRC, computed by excluding any net capital gain and before taking into account any dividends paid deduction for which we are eligible, and 90% of our net income after tax, if any, from property received in foreclosure, over

        (B)  the sum of our qualifying noncash income, e.g., imputed rental income or income from transactions inadvertently failing to qualify as like-kind exchanges.

The distributions must be paid in the taxable year to which they relate, or in the following taxable year if declared before we timely file our tax return for the earlier taxable year and if paid on or before the first regular distribution payment after that declaration. If a dividend is declared in October, November, or December to shareholders of record during one of those months, and is paid during the following January, then for federal income tax purposes the dividend will be treated as having been both paid and received on December 31 of the prior taxable year. A distribution which is not pro rata within a class of our beneficial interests entitled to a distribution, or which is not consistent with the rights to distributions among our classes of beneficial interests, is a preferential distribution that is not taken into consideration for purposes of the distribution requirements, and accordingly the payment of a preferential distribution could affect our ability to meet the distribution requirements. Taking into account our distribution policies, including the dividend reinvestment plan we have adopted, we do not believe that we have made or will make any preferential distributions. The distribution requirements

15

---

may be waived by the IRS if a REIT establishes that it failed to meet them by reason of distributions previously made to meet the requirements of the 4% excise tax discussed below. To the extent that we do not distribute all of our net capital gain and all of our real estate investment trust taxable income, as adjusted, we will be subject to tax on undistributed amounts.

        In addition, we will be subject to a 4% nondeductible excise tax to the extent we fail within a calendar year to make required distributions to our shareholders of 85% of our ordinary income and 95% of our capital gain net income plus the excess, if any, of the "grossed up required distribution" for the preceding calendar year over the amount treated as distributed for that preceding calendar year. For this purpose, the term "grossed up required distribution" for any calendar year is the sum of our taxable income for the calendar year without regard to the deduction for dividends paid and all amounts from earlier years that are not treated as having been distributed under the provision. We will be treated as having sufficient earnings and profits to treat as a dividend any distribution by us up to the amount required to be distributed in order to avoid imposition of the 4% excise tax.

        If we do not have enough cash or other liquid assets to meet the 90% distribution requirements, we may find it necessary and desirable to arrange for new debt or equity financing to provide funds for required distributions in order to maintain our REIT status. We can provide no assurance that financing would be available for these purposes on favorable terms.

        We may be able to rectify a failure to pay sufficient dividends for any year by paying "deficiency dividends" to shareholders in a later year. These deficiency dividends may be included in our deduction for dividends paid for the earlier year, but an interest charge would be imposed upon us for the delay in distribution.

        In addition to the other distribution requirements above, to preserve our status as a REIT we are required to timely distribute C corporation earnings and profits that we inherit from acquired corporations.

Depreciation and Federal Income Tax Treatment of Leases

        Our initial tax bases in our assets will generally be our acquisition cost. We will generally depreciate our real property on a straight-line basis over 40 years and our personal property over the applicable shorter periods. These depreciation schedules may vary for properties that we acquire through tax-free or carryover basis acquisitions, as for example our initial portfolio acquired from CWH as discussed below.

        The initial tax bases and depreciation schedules for the assets we held immediately after we separated from CWH in 2009 depend upon whether the deemed exchange that resulted from that separation was an exchange governed by Sections 351(a), 351(b) and 357(a) of the IRC. Our tax counsel, Sullivan & Worcester LLP, provided to us an opinion that the deemed exchange should be treated as an exchange governed by Sections 351(a) and 357(a) of the IRC, except for up to approximately $6 million of gain recognized by CWH under Section 351(b) of the IRC in respect of our obligation to reimburse CWH for specified offering costs, and we have agreed to and will perform all our tax reporting accordingly. This opinion was conditioned upon the assumption that the transaction agreement had been and will be complied with by all parties thereto, upon the accuracy and completeness of the factual matters described in our Registration Statement on Form S-11 filed in connection with our IPO and upon representations made by us and CWH as to specified factual matters. Therefore, we carried over CWH's tax basis and depreciation schedule in each of the assets that we received from CWH, adjusted appropriately for the up to approximately $6 million of gain recognized by CWH under Section 351(b) of the IRC. This conclusion regarding the applicability of Sections 351(a), 351(b) and 357(a) depended upon favorable determinations with regard to each of the following three issues: (a) Section 351(e) of the IRC did not apply to the deemed exchange, or else it would have disqualified the deemed exchange from Sections 351(a) and 351(b) treatment altogether;

16

---

(b) Section 357(a) rather than Section 357(b) applied to the deemed exchange, or else the liabilities assumed by us from CWH in the deemed exchange would have been taxable consideration (up to the amount of actually realized gains) to CWH; and (c) a judicial recharacterization rule, developed in Waterman Steamship v. Commissioner, 430 F.2d 1185 (5th Cir. 1970), and subsequent tax cases, did not apply to recharacterize our pre-transaction dividends paid to CWH as a taxable sale by CWH for cash. There can be no assurance that the IRS or a court would reach the same conclusion.

        If, contrary to our belief and the opinion of our tax counsel, the deemed exchange were taxable to CWH because Section 351(a), 351(b) or 357(a) of the IRC did not apply, then we would be treated as though we acquired our initial assets from CWH in a mostly or fully taxable acquisition, thereby acquiring aggregate tax bases in these assets greater than the amount that we believe carried over from CWH but also possibly depreciable over longer depreciable lives. In such event, we estimate that our aggregate depreciation deductions for our initial taxable year and many taxable years thereafter could be modestly lower. To address that possibility, we have complied and intend to continue to comply with the annual REIT distribution requirements regardless of whether or not the deemed exchange is treated as a tax free exchange to CWH under Sections 351(a), 351(b) and 357(a) of the IRC, i.e., we determine our distribution requirement assuming the lowest amount of depreciation that could apply. Nevertheless, we may be required to amend our tax reports, including those sent to our shareholders, or may be required to pay deficiency dividends, as discussed above, if the IRS successfully challenges our tax reporting positions.

        We are entitled to depreciation deductions from our facilities only if we are treated for federal income tax purposes as the owner of the facilities. This means that the leases of the facilities must be classified for federal income tax purposes as true leases, rather than as sales or financing arrangements, and we believe this to be the case. In the case of future sale-leaseback arrangements, the IRS could assert that we realize prepaid rental income in the year of purchase to the extent that the value of a leased property, at the time of purchase, exceeds the purchase price for that property. While we believe that the value of leased property at the time of any such purchase will not exceed the purchase price, because of the lack of clear precedent we cannot provide assurances as to whether the IRS might successfully assert the existence of prepaid rental income in any such sale-leaseback transaction.

Taxation of U.S. Shareholders

        The maximum individual federal income tax rate for long-term capital gains is generally 15% (scheduled to increase to 20% for taxable years beginning after December 31, 2012) and for most corporate dividends is generally also 15% (scheduled to increase to ordinary income rates for taxable years beginning after December 31, 2012). However, because we are not generally subject to federal income tax on the portion of our REIT taxable income or capital gains distributed to our shareholders, dividends on our shares generally are not eligible for such 15% tax rate on dividends while that rate is in effect. As a result, our ordinary dividends continue to be taxed at the higher federal income tax rates applicable to ordinary income. However, the favorable federal income tax rates for long-term capital gains, and while in effect, for dividends, generally apply to:

(1)

your long-term capital gains, if any, recognized on the disposition of our shares;



(2)

our distributions designated as long-term capital gain dividends (except to the extent attributable to real estate depreciation recapture, in which case the distributions are subject to a maximum 25% federal income tax rate);



(3)

our dividends attributable to dividends, if any, received by us from non-REIT corporations such as taxable REIT subsidiaries; and



(4)

our dividends to the extent attributable to income upon which we have paid federal corporate income tax.

17

---

        As long as we qualify as a REIT for federal income tax purposes, a distribution to our U.S. shareholders that we do not designate as a capital gain dividend will be treated as an ordinary income dividend to the extent of our current or accumulated earnings and profits. Distributions made out of our current or accumulated earnings and profits that we properly designate as capital gain dividends will be taxed as long-term capital gains, as discussed below, to the extent they do not exceed our actual net capital gain for the taxable year. However, corporate shareholders may be required to treat up to 20% of any capital gain dividend as ordinary income under Section 291 of the IRC.

        In addition, we may elect to retain net capital gain income and treat it as constructively distributed. In that case:

(1)

we will be taxed at regular corporate capital gains tax rates on retained amounts;



(2)

each U.S. shareholder will be taxed on its designated proportionate share of our retained net capital gains as though that amount were distributed and designated a capital gain dividend;



(3)

each U.S. shareholder will receive a credit for its designated proportionate share of the tax that we pay;



(4)

each U.S. shareholder will increase its adjusted basis in our shares by the excess of the amount of its proportionate share of these retained net capital gains over its proportionate share of the tax that we pay; and



(5)

both we and our corporate shareholders will make commensurate adjustments in our respective earnings and profits for federal income tax purposes.

If we elect to retain our net capital gains in this fashion, we will notify our U.S. shareholders of the relevant tax information within 60 days after the close of the affected taxable year.

        As discussed above, for noncorporate U.S. shareholders, long-term capital gains are generally taxed at maximum rates of 15% (scheduled to increase to 20% for taxable years beginning after December 31, 2012) or 25%, depending upon the type of property disposed of and the previously claimed depreciation with respect to this property. If for any taxable year we designate capital gain dividends for U.S. shareholders, then a portion of the capital gain dividends we designate will be allocated to the holders of a particular class of shares on a percentage basis equal to the ratio of the amount of the total dividends paid or made available for the year to the holders of that class of shares to the total dividends paid or made available for the year to holders of all classes of our shares. We will similarly designate the portion of any capital gain dividend that is to be taxed to noncorporate U.S. shareholders at the maximum rates of 15% (scheduled to increase to 20% for taxable years beginning after December 31, 2012) or 25% so that the designations will be proportionate among all classes of our shares.

        Distributions in excess of current or accumulated earnings and profits will not be taxable to a U.S. shareholder to the extent that they do not exceed the shareholder's adjusted tax basis in the shareholder's shares, but will reduce the shareholder's basis in those shares. To the extent that these excess distributions exceed the adjusted basis of a U.S. shareholder's shares, they will be included in income as capital gain, with long-term gain generally taxed to noncorporate U.S. shareholders at a maximum rate of 15% (scheduled to increase to 20% for taxable years beginning after December 31, 2012). No U.S. shareholder may include on his federal income tax return any of our net operating losses or any of our capital losses.

18

---

        If a dividend is declared in October, November, or December to shareholders of record during one of those months, and is paid during the following January, then for federal income tax purposes the dividend will be treated as having been both paid and received on December 31 of the prior taxable year. Also, items that are treated differently for regular and alternative minimum tax purposes are to be allocated between a REIT and its shareholders under Treasury regulations which are to be prescribed. It is possible that these Treasury regulations will require tax preference items to be allocated to our shareholders with respect to any accelerated depreciation or other tax preference items that we claim.

        A U.S. shareholder will generally recognize gain or loss equal to the difference between the amount realized and the shareholder's adjusted basis in our shares that are sold or exchanged. This gain or loss will be capital gain or loss, and will be long-term capital gain or loss if the shareholder's holding period in the shares exceeds one year. In addition, any loss upon a sale or exchange of our shares held for six months or less will generally be treated as a long-term capital loss to the extent of our long-term capital gain dividends during the holding period.

        For taxable years beginning after December 31, 2012, U.S. holders who are individuals, estates or trusts will generally be required to pay a new 3.8% Medicare tax on their net investment income (including dividends on and gains from the sale or other disposition of our shares), or in the case of estates and trusts on their net investment income that is not distributed, in each case to the extent that their total adjusted income exceeds applicable thresholds.

        The IRC imposes a penalty for the failure to properly disclose a "reportable transaction." A reportable transaction currently includes, among other things, a sale or exchange of our shares resulting in a tax loss in excess of (a) $10 million in any single year or $20 million in any combination of years in the case of our shares held by a C corporation or by a partnership with only C corporation partners or (b) $2 million in any single year or $4 million in any combination of years in the case of our shares held by any other partnership or an S corporation, trust or individual, including losses that flow through pass through entities to individuals. A taxpayer discloses a reportable transaction by filing IRS Form 8886 with its federal income tax return and, in the first year of filing, a copy of Form 8886 must be sent to the IRS's Office of Tax Shelter Analysis. The penalty for failing to disclose a reportable transaction is generally $10,000 in the case of a natural person and $50,000 in any other case.

        Noncorporate U.S. shareholders who borrow funds to finance their acquisition of our shares could be limited in the amount of deductions allowed for the interest paid on the indebtedness incurred. Under Section 163(d) of the IRC, interest paid or accrued on indebtedness incurred or continued to purchase or carry property held for investment is generally deductible only to the extent of the investor's net investment income. A U.S. shareholder's net investment income will include ordinary income dividend distributions received from us and, if an appropriate election is made by the shareholder, capital gain dividend distributions received from us; however, distributions treated as a nontaxable return of the shareholder's basis will not enter into the computation of net investment income.

Taxation of Tax-Exempt Shareholders

        In Revenue Ruling 66-106, the IRS ruled that amounts distributed by a REIT to a tax-exempt employees' pension trust did not constitute "unrelated business taxable income," even though the REIT may have financed some of its activities with acquisition indebtedness. Although revenue rulings are interpretive in nature and subject to revocation or modification by the IRS, based upon the analysis and conclusion of Revenue Ruling 66-106, our distributions made to shareholders that are tax-exempt pension plans, individual retirement accounts, or other qualifying tax-exempt entities should not constitute unrelated business taxable income, provided that the shareholder has not financed its acquisition of our shares with "acquisition indebtedness" within the meaning of the IRC, and provided

19

---

further that, consistent with our present intent, we do not hold a residual interest in a real estate mortgage investment conduit.

        Tax-exempt pension trusts that own more than 10% by value of a "pension-held REIT" at any time during a taxable year may be required to treat a percentage of all dividends received from the pension-held REIT during the year as unrelated business taxable income. This percentage is equal to the ratio of:

(1)

the pension-held REIT's gross income derived from the conduct of unrelated trades or businesses, determined as if the pension-held REIT were a tax-exempt pension fund, less direct expenses related to that income, to



(2)

the pension-held REIT's gross income from all sources, less direct expenses related to that income,

except that this percentage shall be deemed to be zero unless it would otherwise equal or exceed 5%. A REIT is a pension-held REIT if:

•

the REIT is "predominantly held" by tax-exempt pension trusts; and



•

the REIT would fail to satisfy the "closely held" ownership requirement discussed above if the stock or beneficial interests in the REIT held by tax-exempt pension trusts were viewed as held by tax-exempt pension trusts rather than by their respective beneficiaries.

A REIT is predominantly held by tax-exempt pension trusts if at least one tax-exempt pension trust owns more than 25% by value of the REIT's stock or beneficial interests, or if one or more tax-exempt pension trusts, each owning more than 10% by value of the REIT's stock or beneficial interests, own in the aggregate more than 50% by value of the REIT's stock or beneficial interests. Because of the share ownership concentration restrictions in our Declaration of Trust, we believe that we are not and will not be a pension-held REIT. However, because our shares are publicly traded, we cannot completely control whether or not we are or will become a pension-held REIT.

        Social clubs, voluntary employee benefit associations, supplemental unemployment benefit trusts and qualified group legal services plans exempt from federal income taxation under Sections 501(c)(7), (c)(9), (c)(17) and (c)(20) of the IRC, respectively, are subject to different unrelated business taxable income rules, which generally will require them to characterize distributions from a REIT as unrelated business taxable income. In addition, these prospective investors should consult their own tax advisors concerning any "set aside" or reserve requirements applicable to them.

Taxation of Non-U.S. Shareholders

        The rules governing the United States federal income taxation of non-U.S. shareholders are complex, and the following discussion is intended only as a summary of these rules. If you are a non-U.S. shareholder, we urge you to consult with your own tax advisor to determine the impact of United States federal, state, local, and foreign tax laws, including any tax return filing and other reporting requirements, with respect to your investment in our shares.

        In general, a non-U.S. shareholder will be subject to regular United States federal income tax in the same manner as a U.S. shareholder with respect to its investment in our shares if that investment is effectively connected with the non-U.S. shareholder's conduct of a trade or business in the United States (and, if provided by an applicable income tax treaty, is attributable to a permanent establishment or fixed base the non-U.S. shareholder maintains in the United States). In addition, a corporate non-U.S. shareholder that receives income that is or is deemed effectively connected with a trade or business in the United States may also be subject to the 30% branch profits tax under Section 884 of the IRC, which is payable in addition to regular United States federal corporate income tax. The balance of this discussion of the United States federal income taxation of non-U.S. shareholders

20

---

addresses only those non-U.S. shareholders whose investment in our shares is not effectively connected with the conduct of a trade or business in the United States.

        A distribution by us to a non-U.S. shareholder that is not attributable to gain from the sale or exchange of a United States real property interest and that is not designated as a capital gain dividend will be treated as an ordinary income dividend to the extent that it is made out of current or accumulated earnings and profits. A distribution of this type will generally be subject to United States federal income tax and withholding at the rate of 30%, or at a lower rate if the non-U.S. shareholder has in the manner prescribed by the IRS demonstrated its entitlement to benefits under a tax treaty. In the case of any in kind distributions of property, we or other applicable withholding agents will collect the amount required to be withheld by reducing to cash for remittance to the IRS a sufficient portion of the property that the non-U.S. shareholder would otherwise receive, and the non-U.S. shareholder may bear brokerage or other costs for this withholding procedure. Because we cannot determine our current and accumulated earnings and profits until the end of the taxable year, withholding at the rate of 30% or applicable lower treaty rate will generally be imposed on the gross amount of any distribution to a non-U.S. shareholder that we make and do not designate a capital gain dividend. Notwithstanding this withholding on distributions in excess of our current and accumulated earnings and profits, these distributions are a nontaxable return of capital to the extent that they do not exceed the non-U.S. shareholder's adjusted basis in our shares, and the nontaxable return of capital will reduce the adjusted basis in these shares. To the extent that distributions in excess of current and accumulated earnings and profits exceed the non-U.S. shareholder's adjusted basis in our shares, the distributions will give rise to tax liability if the non-U.S. shareholder would otherwise be subject to tax on any gain from the sale or exchange of these shares, as discussed below. A non-U.S. shareholder may seek a refund from the IRS of amounts withheld on distributions to him in excess of our current and accumulated earnings and profits.

        From time to time, some of our distributions may be attributable to the sale or exchange of United States real property interests. However, capital gain dividends that are received by a non-U.S. shareholder, including dividends attributable to our sales of United States real property interests, will be subject to the taxation and withholding regime applicable to ordinary income dividends and the branch profits tax will not apply, provided that (1) the capital gain dividends are received with respect to a class of shares that is "regularly traded" on a domestic "established securities market" such as the NYSE, both as defined by applicable Treasury regulations, and (2) the non-U.S. shareholder does not own more than 5% of that class of shares at any time during the one-year period ending on the date of distribution of the capital gain dividends. If both of these provisions are satisfied, qualifying non-U.S. shareholders will not be subject to withholding on capital gain dividends as though those amounts were effectively connected with a United States trade or business, and qualifying non-U.S. shareholders will not be required to file United States federal income tax returns or pay branch profits tax in respect of these capital gain dividends. Instead, these dividends will be subject to United States federal income tax and withholding as ordinary dividends, currently at a 30% tax rate unless reduced by applicable treaty, as discussed below. Although there can be no assurance in this regard, we believe that our common shares have been and will remain "regularly traded" on a domestic "established securities market" within the meaning of applicable Treasury regulations; however, we can provide no assurance that our shares will continue to be "regularly traded" on a domestic "established securities market" in future taxable years.

        Except as discussed above, for any year in which we qualify as a REIT, distributions that are attributable to gain from the sale or exchange of a United States real property interest are taxed to a non-U.S. shareholder as if these distributions were gains effectively connected with a trade or business in the United States conducted by the non-U.S. shareholder. Accordingly, a non-U.S. shareholder that does not qualify for the special rule above will be taxed on these amounts at the normal capital gain rates applicable to a U.S. shareholder, subject to any applicable alternative minimum tax and to a

21

---

special alternative minimum tax in the case of nonresident alien individuals; such a non-U.S. shareholder will be required to file a United States federal income tax return reporting these amounts, even if applicable withholding is imposed as described below; and such a non-U.S. shareholder that is also a corporation may owe the 30% branch profits tax under Section 884 of the IRC in respect of these amounts. We or other applicable withholding agents will be required to withhold from distributions to such non-U.S. shareholders, and remit to the IRS, 35% of the maximum amount of any distribution that could be designated as a capital gain dividend. In addition, for purposes of this withholding rule, if we designate prior distributions as capital gain dividends, then subsequent distributions up to the amount of the designated prior distributions will be treated as capital gain dividends. The amount of any tax withheld is creditable against the non-U.S. shareholder's United States federal income tax liability, and the non-U.S. shareholder may file for a refund from the IRS of any amount of withheld tax in excess of that tax liability.

        A special "wash sale" rule applies to a non-U.S. shareholder who owns any class of our shares if (1) the shareholder owns more than 5% of that class of shares at any time during the one-year period ending on the date of the distribution described below, or (2) that class of our shares is not, within the meaning of applicable Treasury regulations, "regularly traded" on a domestic "established securities market" such as the NYSE. Although there can be no assurance in this regard, we believe that our common shares have been and will remain "regularly traded" on a domestic "established securities market" within the meaning of applicable Treasury regulations, all as discussed above; however, we can provide no assurance that our shares will continue to be "regularly traded" on a domestic "established securities market" in future taxable years. We thus anticipate this wash sale rule to apply, if at all, only to a non-U.S. shareholder that owns more than 5% of either our common shares or any class of our preferred shares. Such a non-U.S. shareholder will be treated as having made a "wash sale" of our shares if it (1) disposes of an interest in our shares during the 30 days preceding the ex-dividend date of a distribution by us that, but for such disposition, would have been treated by the non-U.S. shareholder in whole or in part as gain from the sale or exchange of a United States real property interest, and then (2) acquires or enters into a contract to acquire a substantially identical interest in our shares, either actually or constructively through a related party, during the 61-day period beginning 30 days prior to the ex-dividend date. In the event of such a wash sale, the non-U.S. shareholder will have gain from the sale or exchange of a United States real property interest in an amount equal to the portion of the distribution that, but for the wash sale, would have been a gain from the sale or exchange of a United States real property interest. As discussed above, a non-U.S. shareholder's gain from the sale or exchange of a United States real property interest can trigger increased United States taxes, such as the branch profits tax applicable to non-U.S. corporations, and increased United States tax filing requirements.

        If for any taxable year we designate capital gain dividends for our shareholders, then a portion of the capital gain dividends we designate will be allocated to the holders of a particular class of shares on a percentage basis equal to the ratio of the amount of the total dividends paid or made available for the year to the holders of that class of shares to the total dividends paid or made available for the year to holders of all classes of our shares.

        Tax treaties may reduce the withholding obligations on our distributions. Under some treaties, however, rates below 30% that are applicable to ordinary income dividends from United States corporations may not apply to ordinary income dividends from a REIT or may apply only if the REIT meets certain additional conditions. You must generally use an applicable IRS Form W-8, or substantially similar form, to claim tax treaty benefits. If the amount of tax withheld with respect to a distribution to a non-U.S. shareholder exceeds the shareholder's United States federal income tax liability with respect to the distribution, the non-U.S. shareholder may file for a refund of the excess from the IRS. The 35% withholding tax rate discussed above on some capital gain dividends corresponds to the maximum income tax rate applicable to corporate non-U.S. shareholders but is

22

---

higher than the current 15% and 25% maximum rates on capital gains generally applicable to noncorporate non-U.S. shareholders. Treasury regulations also provide special rules to determine whether, for purposes of determining the applicability of a tax treaty, our distributions to a non-U.S. shareholder that is an entity should be treated as paid to the entity or to those owning an interest in that entity, and whether the entity or its owners are entitled to benefits under the tax treaty. In the case of any in kind distributions of property, we or other applicable withholding agents will have to collect the amount required to be withheld by reducing to cash for remittance to the IRS a sufficient portion of the property that the non-U.S. shareholder would otherwise receive, and the non-U.S. shareholder may bear brokerage or other costs for this withholding procedure.

        If our shares are not "United States real property interests" within the meaning of Section 897 of the IRC, then a non-U.S. shareholder's gain on sale of these shares generally will not be subject to United States federal income taxation, except that a nonresident alien individual who was in the United States for 183 days or more during the taxable year may be subject to a 30% tax on this gain. Our shares will not constitute a United States real property interest if we are a "domestically controlled REIT." A domestically controlled REIT is a REIT in which at all times during the preceding five-year period less than 50% in value of its shares is held directly or indirectly by foreign persons. We believe that we have been and will remain a domestically controlled REIT and thus a non-U.S. shareholder's gain on sale of our shares will not be subject to United States federal income taxation. However, because our shares are publicly traded, we can provide no assurance that we have been or will remain a domestically controlled REIT. If we are not a domestically controlled REIT, a non-U.S. shareholder's gain on sale of our shares will not be subject to United States federal income taxation as a sale of a United States real property interest if that class of shares is "regularly traded," as defined by applicable Treasury regulations, on an established securities market like the NYSE, and the non-U.S. shareholder has at all times during the preceding five years owned 5% or less by value of that class of shares. In this regard, because the shares of others may be redeemed, a non-U.S. shareholder's percentage interest in a class of our shares may increase even if it acquires no additional shares in that class. If the gain on the sale of our shares were subject to United States federal income taxation, the non-U.S. shareholder will generally be subject to the same treatment as a U.S. shareholder with respect to its gain, will be required to file a United States federal income tax return reporting that gain, and a corporate non-U.S. shareholder might owe branch profits tax under Section 884 of the IRC. A purchaser of our shares from a non-U.S. shareholder will not be required to withhold on the purchase price if the purchased shares are regularly traded on an established securities market or if we are a domestically controlled REIT. Otherwise, a purchaser of our shares from a non-U.S. shareholder may be required to withhold 10% of the purchase price paid to the non-U.S. shareholder and to remit the withheld amount to the IRS.

Withholding and Information Reporting

        Information reporting and backup withholding may apply to distributions or proceeds paid to our shareholders under the circumstances discussed below. The backup withholding rate is currently 28% and is scheduled to increase to 31% after 2012. Amounts withheld under backup withholding are generally not an additional tax and may be refunded by the IRS or credited against the shareholder's federal income tax liability. In the case of any in kind distributions of property by us to a shareholder, we or other applicable withholding agents will have to collect any applicable backup withholding by reducing to cash for remittance to the IRS a sufficient portion of the property that our shareholder would otherwise receive, and the shareholder may bear brokerage or other costs for this withholding procedure.

        A U.S. shareholder will be subject to backup withholding when it receives distributions on our shares or proceeds upon the sale, exchange, redemption, retirement or other disposition of our shares,

23

---

unless the U.S. shareholder properly executes, or has previously properly executed, under penalties of perjury an IRS Form W-9 or substantially similar form that:

•

provides the U.S. shareholder's correct taxpayer identification number; and



•

certifies that the U.S. shareholder is exempt from backup withholding because it comes within an enumerated exempt category, it has not been notified by the IRS that it is subject to backup withholding, or it has been notified by the IRS that it is no longer subject to backup withholding.

If the U.S. shareholder has not provided and does not provide its correct taxpayer identification number on the IRS Form W-9 or substantially similar form, it may be subject to penalties imposed by the IRS, and we or other applicable withholding agents may have to withhold a portion of any distributions or proceeds paid to such U.S. shareholder. Unless the U.S. shareholder has established on a properly executed IRS Form W-9 or substantially similar form that it comes within an enumerated exempt category, distributions or proceeds on our shares paid to it during the calendar year, and the amount of tax withheld, if any, will be reported to it and to the IRS.

        Distributions on our shares to a non-U.S. shareholder during each calendar year and the amount of tax withheld, if any, will generally be reported to the non-U.S. shareholder and to the IRS. This information reporting requirement applies regardless of whether the non-U.S. shareholder is subject to withholding on distributions on our shares or whether the withholding was reduced or eliminated by an applicable tax treaty. Also, distributions paid to a non-U.S. shareholder on our shares may be subject to backup withholding, unless the non-U.S. shareholder properly certifies its non-U.S. shareholder status on an IRS Form W-8 or substantially similar form in the manner described above. Similarly, information reporting and backup withholding will not apply to proceeds a non-U.S. shareholder receives upon the sale, exchange, redemption, retirement or other disposition of our shares, if the non-U.S. shareholder properly certifies its non-U.S. shareholder status on an IRS Form W-8 or substantially similar form. Even without having executed an IRS Form W-8 or substantially similar form, however, in some cases information reporting and backup withholding will not apply to proceeds that a non-U.S. shareholder receives upon the sale, exchange, redemption, retirement or other disposition of our shares if the non-U.S. shareholder receives those proceeds through a broker's foreign office.

        After December 31, 2012, the reporting obligations of non-United States financial institutions and other non-United States entities for purposes of identifying accounts and investments held directly or indirectly by United States persons are increased. The failure to comply with these additional information reporting, certification and other specified requirements could result in withholding tax being imposed on payments of dividends and sales proceeds to applicable shareholders or intermediaries. Specifically, a 30% withholding tax is imposed on dividends on and gross proceeds from the sale or other disposition of our shares paid to a foreign financial institution or to a foreign nonfinancial entity, unless (1) the foreign financial institution undertakes applicable diligence and reporting obligations or (2) the foreign non-financial entity either certifies it does not have any substantial United States owners or furnishes identifying information regarding each substantial United States owner. In addition, if the payee is a foreign financial institution, it generally must enter into an agreement with the United States Treasury that requires, among other things, that it undertake to identify accounts held by applicable United States persons or United States-owned foreign entities, annually report specified information about such accounts, and withhold 30% on payments to noncertified holders. If you hold our shares through a non-United States intermediary or if you are a non-United States person, we urge you to consult your own tax advisor regarding foreign account tax compliance.

Other Tax Consequences

        Our tax treatment and that of our shareholders may be modified by legislative, judicial, or administrative actions at any time, which actions may be retroactive in effect. The rules dealing with federal income taxation are constantly under review by the Congress, the IRS and the Treasury Department, and statutory changes, new regulations, revisions to existing regulations, and revised interpretations of established concepts are issued frequently. Likewise, the rules regarding taxes other than federal income taxes may also be modified. No prediction can be made as to the likelihood of passage of new tax legislation or other provisions, or the direct or indirect effect on us and our shareholders. Revisions to tax laws and interpretations of these laws could adversely affect the tax or other consequences of an investment in our shares. We and our shareholders may also be subject to taxation by state, local or other jurisdictions, including those in which we or our shareholders transact business or reside. These tax consequences may not be comparable to the federal income tax consequences discussed above.

        Fiduciaries of a pension, profit-sharing or other employee benefit plan subject to Title I of the Employee Retirement Income Security Act of 1974, as amended, or ERISA, must consider whether:

•

their investment in our shares satisfies the diversification requirements of ERISA;



•

the investment is prudent in light of possible limitations on the marketability of our shares;



•

they have authority to acquire our shares under the applicable governing instrument and Title I of ERISA; and



•

the investment is otherwise consistent with their fiduciary responsibilities.

        Trustees and other fiduciaries of an ERISA plan may incur personal liability for any loss suffered by the plan on account of a violation of their fiduciary responsibilities. In addition, these fiduciaries may be subject to a civil penalty of up to 20% of any amount recovered by the plan on account of a violation. Fiduciaries of any IRA, Roth IRA, tax-favored account (such as an Archer MSA, Coverdell education savings account or health savings account), Keogh Plan or other qualified retirement plan not subject to Title I of ERISA, or non-ERISA plans, should consider that a plan may only make investments that are authorized by the appropriate governing instrument.

        Fiduciaries considering an investment in our securities should consult their own legal advisors if they have any concern as to whether the investment is consistent with the foregoing criteria or is otherwise appropriate. The sale of our securities to a plan is in no respect a representation by us or any underwriter of the securities that the investment meets all relevant legal requirements with respect to investments by plans generally or any particular plan, or that the investment is appropriate for plans generally or any particular plan.

Prohibited Transactions

        Fiduciaries of ERISA plans and persons making the investment decision for an IRA or other non-ERISA plan should consider the application of the prohibited transaction provisions of ERISA and the IRC in making their investment decision. Sales and other transactions between an ERISA or non-ERISA plan, and persons related to it, are prohibited transactions. The particular facts concerning the sponsorship, operations and other investments of an ERISA plan or non-ERISA plan may cause a wide range of other persons to be treated as disqualified persons or parties in interest with respect to it. A prohibited transaction, in addition to imposing potential personal liability upon fiduciaries of ERISA plans, may also result in the imposition of an excise tax under the IRC or a penalty under ERISA upon the disqualified person or party in interest with respect to the plan. If the disqualified person who engages in the transaction is the individual on behalf of whom an IRA or Roth IRA is maintained or his beneficiary, the IRA or Roth IRA may lose its tax-exempt status and its assets may be deemed to have been distributed to the individual in a taxable distribution on account of the prohibited transaction, but no excise tax will be imposed. Fiduciaries considering an investment in our securities should consult their own legal advisors as to whether the ownership of our securities involves a prohibited transaction.

"Plan Assets" Considerations

        The U.S. Department of Labor, which has administrative responsibility over ERISA plans as well as non-ERISA plans, has issued a regulation defining "plan assets." The regulation generally provides that when an ERISA or non-ERISA plan acquires a security that is an equity interest in an entity and that security is neither a "publicly offered security" nor a security issued by an investment company registered under the Investment Company Act of 1940, as amended, the ERISA plan's or non-ERISA

26

---

plan's assets include both the equity interest and an undivided interest in each of the underlying assets of the entity, unless it is established either that the entity is an operating company or that equity participation in the entity by benefit plan investors is not significant.

        Each class of our shares (that is, our common shares and any class of preferred shares that we may issue) must be analyzed separately to ascertain whether it is a publicly offered security. The regulation defines a publicly offered security as a security that is "widely held," "freely transferable" and either part of a class of securities registered under the Exchange Act, or sold under an effective registration statement under the Securities Act of 1933, as amended, provided the securities are registered under the Exchange Act within 120 days after the end of the fiscal year of the issuer during which the offering occurred. Each class of our outstanding shares has been registered under the Exchange Act within the necessary time frame to satisfy the foregoing condition.

        The regulation provides that a security is "widely held" only if it is part of a class of securities that is owned by 100 or more investors independent of the issuer and of one another. However, a security will not fail to be "widely held" because the number of independent investors falls below 100 subsequent to the initial public offering as a result of events beyond the issuer's control. We believe our common shares are and will remain widely held, and we expect the same to be true of any class of preferred shares that we may issue, but we can give no assurances in this regard.

        The regulation provides that whether a security is "freely transferable" is a factual question to be determined on the basis of all relevant facts and circumstances. The regulation further provides that, where a security is part of an offering in which the minimum investment is $10,000 or less, some restrictions on transfer ordinarily will not, alone or in combination, affect a finding that these securities are freely transferable. The restrictions on transfer enumerated in the regulation as not affecting that finding include:

•

any restriction on or prohibition against any transfer or assignment which would result in a termination or reclassification for federal or state tax purposes, or would otherwise violate any state or federal law or court order;



•

any requirement that advance notice of a transfer or assignment be given to the issuer and any requirement that either the transferor or transferee, or both, execute documentation setting forth representations as to compliance with any restrictions on transfer which are among those enumerated in the regulation as not affecting free transferability, including those described in the preceding clause of this sentence;



•

any administrative procedure which establishes an effective date, or an event prior to which a transfer or assignment will not be effective; and



•

any limitation or restriction on transfer or assignment that is not imposed by the issuer or a person acting on behalf of the issuer.

        We believe that the restrictions imposed under our declaration of trust on the transfer of shares do not result in the failure of our shares to be "freely transferable." Furthermore, we believe that there exist no other facts or circumstances limiting the transferability of our shares which are not included among those enumerated as not affecting their free transferability under the regulation, and we do not expect or intend to impose in the future, or to permit any person to impose on our behalf, any limitations or restrictions on transfer which would not be among the enumerated permissible limitations or restrictions.

        Assuming that each class of our shares will be "widely held" and that no other facts and circumstances exist which restrict transferability of these shares, we have received an opinion of our counsel, Sullivan & Worcester LLP, that our shares will not fail to be "freely transferable" for purposes of the regulation due to the restrictions on transfer of the shares under our declaration of trust and that under the regulation each class of our currently outstanding shares is publicly offered and our assets will not be deemed to be "plan assets" of any ERISA plan or non-ERISA plan that invests in our shares.

Item 1A.    Risk Factors

        Our business faces many risks. The risks described below may not be the only risks we face. Additional risks that we do not yet know of, or that we currently think are immaterial, may also impair our business operations or financial results. If any of the events or circumstances described in the following risks occurs, our business, financial condition or results of operations could suffer and the trading price of our securities could decline. Investors and prospective investors should consider the following risks and the information contained under the heading "Warning Concerning Forward Looking Statements" before deciding whether to invest in our securities.

Risks Related to Our Business

We may be unable to lease our properties when our leases expire.

        The weighted average remaining term of our leases in effect as of December 31, 2010 is 4.5 years based upon annual rental income and 4.3 years based upon occupied square footage. As of December 31, 2010, leases representing approximately 42.2% of our rental income and 44.9% of our occupied square footage will expire by December 31, 2013. Although we will seek to renew our leases with current tenants when these leases expire, we can provide no assurance that we will be successful in doing so. If our tenants do not renew their leases, we may be unable to enter leases with substitute tenants.

When we renew leases or lease to new tenants our rents may decline and our expenses may increase.

        When we renew leases or lease to new tenants we may receive less rent than we received under the leases that expired. Laws and regulations applicable to government leasing often require public solicitations of bids when new or renewal leases are being considered. Market conditions may require us to lower our rents to retain government tenants. Some of our current rents include payments to amortize the cost of tenant improvements which government tenants may be unwilling to pay or contractually allowed to eliminate when leases are renewed. Also, whenever we renew leases or lease to new tenants we may have to spend substantial amounts for tenant fit out, leasing commissions and other tenant inducements. As a consequence of lower rents or increased expenses when we renew leases or lease to new tenants, our net income and cash available to pay distributions to you may decline.

We may be unable to identify additional properties to acquire and grow our business.

        Our business plan is to acquire additional properties that are majority leased to government tenants. There are a limited number of such properties, and we will have fewer opportunities to grow our investments than REITs that purchase properties that are leased to both government and non-government tenants or that are not leased when they are acquired. Accordingly, our business plan to acquire additional properties that are majority leased to government tenants may not succeed.

We may be unable to access the capital necessary to repay debts, invest in our properties or fund acquisitions.

        To retain our status as a REIT, we are required to distribute at least 90% of our annual REIT taxable income (excluding capital gains) and satisfy a number of organizational and operational requirements to which REITs are subject. Accordingly, we generally will not be able to retain sufficient cash from operations to repay debts, invest in our properties or fund acquisitions. Our business and growth strategies depend, in part, upon our ability to raise additional capital at reasonable costs to repay our debts, invest in our properties and fund new acquisitions. Recently, there has been a significant volatility in the amount of capital available for real estate investments on a global basis. Our ability to raise reasonably priced capital is not guaranteed; we may be unable to raise reasonably priced capital because of reasons related to our business or for reasons beyond our control, such as market

28

---

conditions. If we are unable to raise reasonably priced capital, our business and growth strategies may fail.

We face significant competition.

        We plan to acquire properties that are majority leased to government tenants whenever we are able to identify such investment opportunities and have sufficient available financing to complete such acquisitions. We face competition for acquisition opportunities from other investors and this competition may subject us to the following risks:

•

we may be unable to acquire a desired property because of competition from other well capitalized real estate investors, including other REITs, financial institutions, individuals and public and private companies who are engaged in our business; and



•

competition from other real estate investors may significantly increase the purchase price we must pay to acquire properties, especially as access to debt capital becomes more readily available and lending terms become more lenient.

        In addition, substantially all of our properties face competition for tenants. Some competing properties may be newer, better located and more attractive to tenants. Competing properties may have lower rates of occupancy than our properties, which may result in competing owners leasing available space at lower rents than we offer at our properties. This competition may affect our ability to attract and retain tenants and may reduce the rents we are able to charge. Government tenants may be particularly difficult to attract and retain because they may be viewed as desirable tenants by other landlords.

Our acquisitions may not be successful.

        Our business strategy contemplates acquisitions of additional properties. We cannot assure you that acquisitions we make will prove to be successful. Notwithstanding pre-acquisition due diligence, we do not believe that it is possible to fully understand a property before it is owned and operated for an extended period of time. For example, we could acquire a property that contains undisclosed defects in design or construction. In addition, after our acquisition of a property, the market in which the acquired property is located may experience unexpected changes that adversely affect the property's value. The occupancy of properties that we acquire may decline during our ownership, and rents that are in effect at the time a property is acquired may decline thereafter. Also, our property operating expenses at properties we acquire may be higher than we anticipated at the time of our acquisitions and such acquisitions may not yield the returns we expect and, if financed using debt or new equity issuances, may result in shareholder dilution. For these reasons, among others, our property acquisitions may cause us to experience losses.

The U.S. Government's "green lease" policies may adversely affect us.

        In recent years the U.S. Government has instituted "green lease" policies which allow a government tenant to require leadership in energy and environmental design for commercial interiors, or LEED®-CI, certification in selecting new premises or renewing leases at existing premises. In addition, the Energy Independence and Security Act of 2007 allows the GSA to prefer buildings for lease that have received an "Energy Star" label. Obtaining such certifications and labels may be costly and time consuming, but our failure to do so may result in our competitive disadvantage in acquiring new or retaining existing government tenants.

29

---

Some government tenants have the right to terminate their leases prior to their lease expiration date.

        Almost all of our current rents come from government tenants. Some of our leases with government tenants allow the tenants to vacate the leased premises before the stated terms of the leases expire with little or no liability. In particular:

•

Tenants occupying approximately 16.5% of our rentable square feet and contributing approximately 11.8% of our annualized rental income as of December 31, 2010, have currently exercisable rights to terminate their leases before the stated term of their lease expires.



•

In 2011, 2012, 2013, 2014, 2015, 2016, 2017 and 2019, early termination rights become exercisable by other tenants who currently occupy an additional approximately 1.9%, 2.3%, 1.0%, 2.4%, 0.3%, 3.2%, 0.4% and 1.3% of our rentable square feet, respectively, and contribute an additional approximately 2.8%, 1.9%, 1.3%, 2.6%, 0.3%, 3.7%, 0.7% and 2.3% of our annualized rental income, respectively, as of December 31, 2010.



•

Seven of our state government tenants have the currently exercisable right to terminate their leases if these states do not appropriate rent in their respective annual budgets. These seven tenants occupy approximately 5.6% of our rentable square feet and contribute approximately 6.2% of our annualized rental income as of December 31, 2010.

        For fiscal policy reasons, security concerns or other reasons, some or all of our government tenants may decide to vacate our properties. If a significant number of such vacancies occur, our rental income may materially decline and we may become unable to pay regular distributions to you or we may reduce the amounts of such distributions.

We currently have a concentration of properties in the Washington, DC metro area and are exposed to changes in market conditions in this area.

        Approximately 30.3% of our annualized rental income as of December 31, 2010 was received from properties located in the Washington, DC metro area. A downturn in economic conditions in this area could result in reduced demand from tenants for our properties or lower the rents that our government tenants in this area are willing to pay when our leases expire and renewal terms are negotiated. Additionally, within the past few years there has been a large number of speculative real estate developments in the Washington, DC metro area, and a surplus of newly developed space could adversely affect our ability to retain our government tenants when our leases expire.

Our failure or inability to meet certain terms of our unsecured revolving credit facility would adversely affect our business and may prevent our paying distributions to you.

        Our $500 million unsecured revolving credit facility includes various conditions to our borrowing and various financial and other covenants and events of default. We may not be able to satisfy all of these conditions or may default on some of these covenants for various reasons, including matters which are beyond our control. If we are unable to borrow under our unsecured revolving credit facility we may be unable to meet our business obligations or to grow by buying additional properties, or we may be required to sell some of our properties. If we default under our unsecured revolving credit facility at a time when borrowed amounts are outstanding under our unsecured revolving credit facility, our lenders may demand immediate payment. Any default under our outstanding unsecured revolving credit facility would likely have serious and adverse consequences to us and would likely cause the market price of our securities to materially decline and may prevent our paying distributions to you.

30

---

Amounts recoverable under our leases for increased operating costs may be less than the actual increased costs.

        Under most of our leases, the tenant's obligation to pay us adjusted rent for increased operating costs (e.g. the costs of cleaning services, supplies, materials, maintenance, trash removal, landscaping, water, sewer charges, heating, electricity and certain administrative expenses) is increased annually based on a cost of living index rather than the actual amount of our costs. Accordingly, the amount of any rent adjustment may not fully offset any increased costs we may incur in providing these services, including any increased energy costs which result from climate change laws designed to reduce carbon emissions.

Increasing interest rates may adversely affect us and the value of your investment in our securities.

        There are three principal ways that increasing interest rates may adversely affect us and the value of an investment in our securities:

•

Funds borrowed under our unsecured revolving credit facility bear interest at variable rates. If interest rates increase, so will our interest costs, which could adversely affect our cash flow, our ability to pay principal and interest on our debt, our cost of refinancing our debt when it becomes due and our ability to pay distributions.



•

An increase in interest rates could decrease the amount buyers may be willing to pay for our properties, thereby reducing the market value of our properties and limiting our ability to sell properties or to obtain mortgage financing secured by our properties.



•

We expect to pay regular distributions on our Shares. When interest rates on debt investments available to investors rise, the market prices of distribution paying securities often decline. Accordingly, if interest rates rise, the market price of our Shares may decline.

Real estate ownership creates risks and liabilities.

        Our business is subject to risks associated with real estate ownership, including:

•

property and casualty losses, some of which may be uninsured;



•

defaults by our tenants;



•

the illiquid nature of real estate markets which limits our ability to sell our assets rapidly to respond to changing market conditions;



•

costs that may be incurred relating to property maintenance and repair, and the need to make expenditures due to changes in governmental regulations, including the Americans with Disabilities Act; and



•

asbestos, lead and mold related liabilities and costs of containment or removal and other environmental hazards at our properties for which we may be liable, including those created by prior owners or occupants, existing tenants, adjacent properties or other parties.

Acquisition and ownership of real estate is subject to environmental and climate change risks.

        Acquisition and ownership of real estate is subject to risks associated with environmental hazards. We may be liable for environmental hazards at our properties, including those created by prior owners or occupants, existing tenants, abutters or other persons. Our properties may be subject to environmental laws for certain hazardous substances used to maintain these properties, such as chemicals used to clean, pesticides and lawn maintenance materials, and for other conditions, such as the presence of harmful mold. Various federal and state laws impose environmental liabilities upon property owners, such as us, for any environmental damages arising on properties they own or occupy,

31

---

and we are not assured that we will not be held liable for environmental clean up at our properties, including environmental damages at sites we own and lease to our tenants. As an owner or previous owner of properties which contain environmental hazards, we also may be liable to pay damages to governmental agencies or third parties for costs and damages they incur arising from environmental hazards at the properties. Moreover, the costs and damages which may arise from environmental hazards are often difficult to project.

        The current political debate about climate change has resulted in various existing and proposed treaties, laws and regulations which are intended to limit carbon emissions. We believe these treaties, laws and regulations being enacted or proposed may cause energy costs at our properties to increase, but we do not expect the direct impact of these increases to be material to our results of operations because the increased costs either would be the responsibility of our tenants directly or in large part may be passed through by us to our tenants as additional lease payments. Although we do not believe it is likely in the foreseeable future, laws enacted to mitigate climate change may make some of our buildings obsolete or cause us to make material investments in our properties which could materially and adversely affect our financial condition and results of operations.

Risks Related to Our Relationships with CWH and RMR

As long as CWH retains significant ownership of us, your ability to influence matters requiring shareholder approval will be limited.

        As of February 24, 2011, CWH owned approximately 24.6% of our outstanding Shares. For so long as CWH continues to retain a significant ownership stake in us, CWH may be able to elect all of the members of our Board of Trustees, including our Independent Trustees, and may effectively control the outcome of shareholder actions. As a result, CWH may have the ability to control all matters affecting us, including:

•

the composition of our Board of Trustees and, through our Board of Trustees, determinations with respect to our management, business plans and policies, including the appointment and removal of our officers;



•

determinations with respect to mergers and other business combinations;



•

our acquisition or disposition of assets;



•

our financing activities;



•

the payment of distributions on our Shares; and



•

the number of Shares available for issuance under our equity incentive plans.

        CWH's significant ownership in us and resulting ability to effectively control us may discourage transactions involving a change of control.

CWH's ability to sell its ownership stake in us and speculation about such possible sales may adversely affect the market price of our Shares.

        CWH is not generally prohibited from selling some or all of its Shares, and CWH may do so without our approval. CWH has advised us that it does not have any current plans to sell or otherwise dispose of its Shares. However, CWH has a history of successfully divesting certain of its properties into new REITs and then selling or distributing its stake in such REITs over time. So long as CWH continues to retain significant ownership in us, the liquidity and market price of our Shares may be adversely impacted. In addition, speculation by the press, stock analysts, shareholders or others regarding CWH's intention to dispose of its Shares could adversely affect the market price of our

32

---

Shares. Accordingly, your Shares may be worth less than they would be if CWH did not have significant ownership in us.

Our management structure and our manager's other activities may create conflicts of interest.

        We have no employees. Personnel and services that we require are provided to us under contract by RMR. RMR is authorized to follow broad operating and investment guidelines and, therefore, has great latitude in determining the properties that will be proper investments for us, as well as making individual investment decisions for us. Our Board of Trustees periodically reviews our operating and investment guidelines and our properties' operations, but it does not review or approve each decision made by RMR on our behalf. In addition, in conducting periodic reviews, our Board of Trustees relies primarily on information provided to it by RMR. RMR is beneficially owned by our Managing Trustees, Barry Portnoy and Adam Portnoy. Barry Portnoy is Chairman, and Adam Portnoy is President, Chief Executive Officer and a director, of RMR. All of the members of our Board of Trustees, including our Independent Trustees, are members of one or more boards of trustees or directors of various companies managed by RMR. All of our executive officers are also executive officers of RMR. The foregoing individuals may hold equity in or positions with other companies managed by RMR. Such equity ownership and positions by our Trustees and officers could create, or appear to create, conflicts of interest with respect to matters involving us, RMR and its affiliates.

        RMR also acts as the manager for three other publicly traded REITs: CWH, which primarily owns and operates commercial office and industrial buildings and leased industrial land; SNH, which primarily owns healthcare senior living properties and medical office buildings; and HPT, which owns hotels and travel centers. RMR also provides management services to other private and public companies, including FVE, which operates senior living communities, including independent living and congregate care communities, assisted living communities, nursing homes and hospitals; and TA, which operates and franchises travel centers. These multiple responsibilities to public companies and RMR's other businesses could create competition for the time and efforts of RMR and Messrs. Barry and Adam Portnoy. Also, RMR's multiple responsibilities to us and CWH may create actual and potential conflicts of interest, and these conflicts can be especially severe in periods of financial stress.

Our management agreements with RMR were negotiated between affiliated parties and may not be as favorable to us as they would have been if negotiated between unaffiliated parties.

        We pay RMR business management fees based upon the historical cost of our investments (including acquisition costs) which at any time may be more or less than the fair market value thereof, plus an incentive fee based upon certain increases in our FFO Per Share, as defined in our business management agreement with RMR. We also pay RMR property management fees based in part upon the gross rents we collect from tenants and the costs of construction we incur. For more information, see "Business—Manager." Our fee arrangements with RMR could encourage RMR to advocate acquisitions of properties, to undertake unnecessary construction activities or to overpay for acquisitions or construction. These arrangements may also encourage RMR to discourage sales of properties by us. Although we believe we benefit from our management by RMR, our management agreements were negotiated between affiliated parties, and the terms, including the fees payable to RMR, may not be as favorable to us as they would have been were they negotiated on an arm's length basis between unaffiliated parties.

Our management agreements with RMR may discourage our change of control.

        Termination of our management agreements with RMR would be a default under our unsecured revolving credit facility unless approved by a majority of our lenders. RMR is able to terminate its management agreements with us if we experience a change of control. The quality and depth of management available to us by contracting with RMR may not be able to be duplicated by our being a

33

---

self managed company or by our contracting with unrelated third parties, without considerable cost increases. For these reasons, our management agreements may discourage a change of control of us.

The potential for conflicts of interest as a result of our management structure may provoke dissident shareholder activities that result in significant costs.

        In the past, in particular following periods of financial distress or volatility in the market price of a company's securities, shareholder litigation, dissident trustee nominations and dissident proposals have often been instituted against companies alleging conflicts of interest in business dealings with trustees, affiliated persons and entities. Our relationship with RMR, with Messrs. Barry and Adam Portnoy and with RMR affiliates may precipitate such activities. These activities, if instituted against us, could result in substantial costs and a diversion of our management's attention and resources, even if they are without merit.

Provisions in the transaction agreement and our management agreements with RMR may restrict our investment activities and create conflicts of interest.

        The transaction agreement we entered with CWH at the time of our IPO and our management agreements with RMR restrict our ability to make investments in properties that are within the investment focus of another business now or in the future managed by RMR. In addition, RMR has discretion to determine whether a particular investment opportunity is within our investment focus or that of another business managed by RMR. As a result of these contractual provisions, we have limited ability to invest in properties that are within the investment focus of other businesses managed by RMR or properties that are not, at the time of our investment, properties majority leased to government tenants. These agreements do not restrict our ability, or the ability of other businesses managed by RMR, to lease properties to any particular tenant, and, as a result, we may compete with other businesses managed by RMR for tenants. Our management agreements afford RMR discretion to determine which leasing opportunities to present to us or to other businesses managed by RMR. Accordingly, we may compete with other businesses managed by RMR for investments in properties that are not within the investment focus of us or another business managed by RMR and for tenants. There is no assurance that any conflicts of interest created by such competition will be resolved in our favor.

We depend upon RMR to manage our business and implement our growth strategy.

        Our ability to achieve our business objectives depends on RMR and its ability to manage our properties, source and complete new acquisitions for us on favorable terms and to execute our financing strategy on favorable terms. Because we are externally managed, our business is dependent upon RMR's business contacts, its ability to successfully hire, train, supervise and manage its personnel and its ability to maintain its operating systems. If we lose the services provided by RMR or its key personnel, our business and growth prospects may decline. We may be unable to duplicate the quality and depth of management available to us by becoming a self managed company or by hiring another manager. Also, in the event RMR is unwilling or unable to continue to provide management services to us, our cost of obtaining substitute services may be greater than the management fees we pay RMR, and as a result our earnings and cash flows may decline.

We may experience losses from our business dealings with Affiliates Insurance Company.

        We have invested approximately $5.2 million in Affiliates Insurance Company, or AIC, we have purchased substantially all our property insurance in a program designed and reinsured in part by AIC, and we are currently investigating the possibilities to expand our relationship with AIC to other types of insurance. Our principal reason for investing in AIC and for purchasing insurance in these programs is to seek to improve our financial results by obtaining improved insurance coverages at lower costs

34

---

than may be otherwise available to us or by participating in any profits which we may realize as an owner of AIC. AIC's business involves the risks typical of insurance businesses. Accordingly, our anticipated financial benefits from our business dealings with AIC may be delayed or not achieved, and we may experience losses from these dealings.

Risks Related to Our Organization and Structure

Ownership limitations and anti-takeover provisions in our Declaration of Trust and Bylaws, as well as certain provisions of Maryland and other laws, may prevent our shareholders from receiving a takeover premium or implementing beneficial changes.

        Our Declaration of Trust prohibits any shareholder other than CWH, RMR and their affiliates from owning more than 9.8% of the number or value of our Shares or of any other class or series of our outstanding shares. This provision of our Declaration of Trust is intended to assist with our REIT compliance under the IRC and otherwise to promote our orderly governance. However, this provision also inhibits acquisitions of a significant stake in us and may prevent a change in our control. Additionally, many provisions contained in our Declaration of Trust and Bylaws and under Maryland and other laws may further deter persons from attempting to acquire control of us and implement changes that may be beneficial to shareholders, including, for example, provisions relating to:

•

the division of our Trustees into three classes, with the term of one class expiring each year, and in each case, until a successor is elected and qualifies, which could delay a change in our control;



•

required qualifications for an individual to serve as a trustee and a requirement that certain of our trustees be "Managing Trustees" and other trustees be "Independent Trustees";



•

limitations on the ability of shareholders to propose nominees for election as trustees and propose other business for a meeting of shareholders;



•

the two-thirds shareholder vote required for removal of trustees;



•

the authority of our Board of Trustees, and not our shareholders, to adopt, amend or repeal our Bylaws;



•

the fact that only the Board of Trustees may call shareholder meetings and that shareholders are not entitled to act without a meeting;



•

because of our ownership of AIC, we are an insurance holding company under applicable state law; accordingly, anyone who intends to solicit proxies for a person to serve as one of our Trustees for another proposal of business not approved by our Board of Trustees may be required to receive pre-clearance from the concerned insurance regulators;



•

a requirement that a shareholder who desires to nominate a person for election as trustee or to propose other business not approved by our Board of Trustees at a meeting of our shareholders that would cause a breach or default of any debt instrument or agreement or other material agreement of ours, to provide (i) evidence of the lender's or contracting party's willingness to waive the breach of covenant or default or (ii) a detailed plan for repayment of the applicable indebtedness or curing the contractual breach or default and satisfying any resulting damage, in each case, satisfactory to our Board of Trustees; and



•

the authority of our Board of Trustees to adopt certain amendments to our Declaration of Trust without shareholder approval, including the authority to increase or decrease the aggregate number of authorized shares, to create new classes or series of shares (including a class or series of shares that could delay or prevent a transaction or a change in our control that might involve a premium for our shares), to increase or decrease the authorized number of shares of any class

35

---

or series, and to classify or reclassify any unissued shares from time to time by setting or changing the preferences, conversion or other rights, voting powers, restrictions, limitations as to distributions, qualifications or terms or conditions of redemption of our shares or any new class or series of shares created by our Board of Trustees.

        In addition, certain provisions of Maryland law may have an anti-takeover effect. For all of these reasons, our shareholders may be unable to realize a change of control premium for our shares they own or otherwise effect a change of our policies.

Our rights and the rights of our shareholders to take action against our trustees and officers are limited.

        Our Declaration of Trust limits the liability of our trustees and officers to us and our shareholders for money damages to the maximum extent permitted under Maryland law. Under current Maryland law, our trustees and officers will not have any liability to us and our shareholders for money damages other than liability resulting from:

•

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



•

active and deliberate dishonesty by the trustee or officer that was established by a final judgment as being material to the cause of action adjudicated.

        Our Bylaws and indemnity contracts require us to indemnify any present or former trustee or officer, to the maximum extent permitted by Maryland law, who is made or threatened to be made a party to a proceeding by reason of his or her service in that capacity. In addition, we may be obligated to pay or reimburse the expenses incurred by our present and former Trustees and officers without requiring a preliminary determination of their ultimate entitlement to indemnification. As a result, we and our shareholders may have more limited rights against our present and former Trustees and officers than might otherwise exist absent the provisions in our Bylaws and indemnity contracts or that might exist with other companies, which could limit your recourse in the event of actions not in your best interest.

Disputes with CWH and RMR and shareholder litigation against us or our trustees and officers may be referred to arbitration proceedings.

        Our contracts with CWH and RMR provide that any dispute arising under those contracts may be referred to binding arbitration proceedings. Similarly our Declaration of Trust and Bylaws provide that actions by our shareholders against us or against our Trustees and officers, including derivative and class actions, may be referred to binding arbitration proceedings. As a result, we and our shareholders would not be able to pursue litigation for these disputes in courts against CWH, RMR or our Trustees and officers if the disputes were referred to arbitration. In addition, the ability to collect attorneys' fees or other damages may be limited in the arbitration proceedings, which may discourage attorneys from agreeing to represent parties wishing to commence such a proceeding.

We may change our operational and investment policies without shareholder approval.

        Our Board of Trustees determines our operational and investment policies and may amend or revise our policies, including our policies with respect to our intention to qualify for taxation as a REIT, acquisitions, dispositions, growth, operations, indebtedness, capitalization and distributions, or approve transactions that deviate from these policies, without a vote of, or notice to, our shareholders. Such policy changes could adversely affect the market value of our Shares and our ability to make distributions to you.

Risks Related to Our Taxation

The loss of our tax status as a REIT for U.S. federal income tax purposes could have significant adverse consequences.

        As a REIT, we generally do not pay federal and state income taxes. However, actual qualification as a REIT under the IRC depends on satisfying complex statutory requirements, for which there are only limited judicial and administrative interpretations. We believe we have been organized and have operated, and will continue to be organized and to operate, in a manner that qualified and will continue to qualify us to be taxed under the IRC as a REIT. However, we cannot assure that, upon review or audit, the IRS will agree with this conclusion. Maintaining our status as a REIT will require us to continue to satisfy certain tests concerning, among other things, the nature of our assets, the sources of our income and the amounts we distribute to our shareholders. In order to meet these requirements, it may be necessary for us to sell or forego attractive investments. If we cease to be a REIT, then our ability to raise capital might be adversely affected, we will be in breach under our unsecured revolving credit facility, we may be subject to material amounts of federal and state income taxes and the value of our Shares likely would decline. In addition, if we lose or revoke our tax status as a REIT for a taxable year, we will generally be prevented from requalifying as a REIT for the next four taxable years.

Distributions to shareholders generally will not qualify for reduced tax rates.

        The maximum tax rate for dividends payable by U.S. corporations to individual stockholders is 15% through 2012. Distributions paid by REITs, however, generally are not eligible for this reduced rate. The more favorable rates for corporate dividends may cause investors to perceive that investment in REITs is less attractive than investment in non-REIT corporations that pay dividends, thereby reducing the demand and market price of our Shares.

Risks Related to Our Securities

There is no assurance that we will continue to make distributions.

        We intend to continue to pay regular quarterly distributions to our shareholders. However:

•

our ability to pay distributions will be adversely affected if any of the risks described herein occur;



•

our payment of distributions is subject to compliance with restrictions contained in our unsecured revolving credit facility; and



•

any distributions will be made in the discretion of our Board of Trustees and will depend upon various factors that our Board of Trustees deems relevant, including our financial condition, maintenance of our REIT tax status, and our ability to access capital. Differences between our income for financial reporting purposes and for applicable federal income tax purposes may also affect the determination of our common share distributions. There are no assurances of our ability to pay distributions in the future. In addition, our distributions in the past have included, and may in the future include, a return of capital.

        For these reasons, among others, our distribution rate may decline or we may cease making distributions.

PART II

Item 5.    Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

        Our Shares have traded on the NYSE (symbol: GOV) since June 3, 2009. The following table sets forth for the periods indicated the high and low sale prices for our Shares as reported by the NYSE:

        The closing price of our Shares on the NYSE on February 18, 2010, was $26.58 per Share.

        As of February 18, 2010, there were 60 shareholders of record, and we estimate that as of such date there were in excess of 20,600 beneficial owners of our Shares

        Information about our distributions paid to common shareholders is summarized in the table below. Share distributions are generally paid in the quarter following the quarter to which they relate.

        All Share distributions shown in the table above have been paid. Our current quarterly distribution rate is $0.41 per Share ($1.64 on an annualized basis). However, the timing and amount of our distributions will be at the discretion of our Board of Trustees and will depend on various factors that our Board of Trustees deems relevant, including our results of operations, our financial condition, our capital requirements, our FFO, our cash available for distribution, restrictive covenants in our financial or other contractual arrangements, general economic conditions and restrictions under Maryland law. Therefore, there can be no assurance that we will continue to pay distributions in the future or that the amount of any distributions we do pay will not decrease.

Item 7.    Management's Discussion and Analysis of Financial Condition and Results of Operations

        The following information should be read in conjunction with our consolidated financial statements and accompanying notes included elsewhere in this Annual Report on Form 10-K.

OVERVIEW

        As of December 31, 2010, we owned 55 properties located in 25 states and the District of Columbia containing approximately 6.8 million rentable square feet. The U.S. Government and state governments are our primary tenants, representing 93.0% and 93.7% of our annualized rental income as of December 31, 2010 and 2009, respectively.

Property Operations

        As of December 31, 2010, 96.1% of our rentable square feet were leased, compared to 99.9% of our rentable square feet as of December 31, 2009. Occupancy data for 2010 and 2009 is as follows (square feet in thousands):

        We believe that leasing market conditions generally stabilized during 2010, but remain weak in most U.S. markets. However, the historical experience of our manager, RMR, has been that government tenants frequently renew leases to avoid the costs and disruptions that may result from relocating their operations. We believe that the expected increase in government regulation resulting from the healthcare and financial reform legislation will increase the U.S. Government's demand for leased office space. Similarly, we believe that budgetary pressures may cause an increased demand for leased space, as opposed to government owned space, among government tenants generally and especially among state and local government tenants. For these and other reasons we believe that occupancy at our government leased properties may outperform national market averages. However, several members of Congress have recently announced intentions to scale back government expansion plans enacted in the past two years. There are too many variables for us to reasonably project what the financial impact of market conditions and political events will be on our results for future periods.

43

---

        Lease renewals and rental rates at which available space in our properties may be relet in the future will depend, in part, on prevailing market conditions at that time. Lease expirations at our properties by year, as of December 31, 2010, are as follows (square feet and dollars in thousands):

        The U.S. Government and six state governments were responsible for approximately 93.0% of our annual rental income as of December 31, 2010. The U.S. Government and four state governments were responsible for approximately 93.7% of our annual rental income as of December 31, 2009. The U. S. Government is our largest tenant and was responsible for approximately 78.2% and 83.1% of our rental income as of December 31, 2010 and 2009, respectively.

Investment Activities (dollar amounts in thousands)

        In January 2010, we acquired an office property located in Lakewood, CO that contains 166,745 rentable square feet. This property is 100% leased to the U.S. Government and occupied by the

        In June 2010, we entered a series of agreements with certain subsidiaries of CWH for the purchase of 15 properties with approximately 1.9 million rentable square feet for an aggregate purchase price of $231,000, excluding acquisition costs, and shortly thereafter acquired three of these properties with 304,733 rentable square feet for $40,380, excluding acquisition costs. In July 2010, we acquired five of these properties that contain 441,284 rentable square feet for an aggregate purchase price of $48,339, excluding acquisition costs. In August 2010, we acquired two of these properties that contain 287,406 rentable square feet for an aggregate purchase price of $75,316, excluding acquisition costs. In September 2010, we acquired the remaining five of these properties that contain 837,107 rentable square feet for an aggregate purchase price of $66,965, excluding acquisition costs. These properties are majority leased to the U.S. Government and the State of South Carolina and are occupied by various federal and state government agencies.

        In October 2010, we acquired an office property located in Tampa, FL with 67,917 rentable square feet. This property is 100% leased to the U.S. Government and occupied by the Department of Veterans Affairs. The purchase price was $13,500, which includes the assumption of $9,755 of mortgage debt that is not currently prepayable and excludes acquisition costs.

        In December 2010, we acquired an office property located in Trenton, NJ with 266,995 rentable square feet. This property is 96% leased to 15 tenants, of which 65% is leased to the State of New Jersey and occupied by the New Jersey Department of the Treasury. The U.S. Government also occupies 10% of the property, including space occupied by the Department of Justice and the Internal Revenue Service. The purchase price was $46,050, excluding acquisition costs.

        In September 2010, we entered into a purchase and sale agreement to acquire an office property located in Quincy, MA with 92,549 rentable square feet.

The properties are 100% leased to two tenants, of which 94% is leased to the U.S. Government and occupied by the Social Security Administration. We completed the purchase of this property in February 2011 for $28,000, excluding acquisition costs.

Financing Activities (dollar amounts in thousands, except per share amounts)

        In January 2010, we sold 9,775,000 of our Shares in a public offering at a price of $21.50 per Share and raised net proceeds of $199,030. The funds from this offering were used to reduce amounts outstanding under our initial $250,000 secured revolving credit facility and to fund our business activities, including some of our acquisitions.

        In January 2010, we assumed a mortgage with an outstanding balance of $10,396 and a fair value of $11,458 as part of our Lakewood, CO acquisition. This note requires interest at 8.15% and is amortized on a 20 year schedule until maturity in March 2021. We recorded a $1,062 premium on this assumed debt, which reduced its effective interest rate to 6.15%, because we believed the interest rate payable under this mortgage was above the rate we would have had to pay for debt with the same maturity at the time we assumed this obligation.

        In February 2010, we assumed a mortgage of $24,800 as part of our Landover, MD property acquisition. The note requires interest at 6.21%. No principal payment is required until September 2011, at which time the note is amortized on a 30 year schedule until its maturity in August 2016. We estimated that the terms of this note were at market value at the time of this loan assumption.

        In August 2010, we sold 9,200,000 of our Shares in a public offering at $25.00 per share and raised net proceeds of $219,900. The funds from this offering were used to reduce amounts outstanding under our secured revolving credit facility and to fund our business activities, including some of our acquisitions.

        In October, 2010, we replaced our initial $250,000 secured revolving credit facility with our $500,000 unsecured revolving credit facility. Our unsecured revolving credit facility has a maturity date of October 28, 2013 and, subject to certain conditions and the payment of a fee, we may extend the maturity date to October 28, 2014. Interest under the new unsecured revolving credit facility is based upon LIBOR plus a spread that is subject to adjustment based on changes to our senior unsecured debt ratings. We believe the financial and restrictive covenants applicable to us under our unsecured revolving credit facility are similar to the financial and restrictive covenants for other REITs that have investment grade senior unsecured debt ratings.

        In October 2010, we assumed a mortgage of $9,755 as part of our Tampa, FL property acquisition. This note requires interest at 7.00% and is amortized on a 30 year schedule until maturity in March 2019. We recorded a $1,148 premium on this assumed debt, which reduced its effective interest rate to 5.15%, because we believed the interest rate payable under this mortgage was above the rate we would have had to pay for debt with the same maturity at the time we assumed this obligation.

RESULTS OF OPERATIONS (dollar amounts in thousands, except per share amounts)

Year Ended December 31, 2010, Compared to Year Ended December 31, 2009

        Rental income.    The increase in rental income between 2010 and 2009 primarily reflects the effects of property acquisitions. Rental income at the properties we owned continuously in both years declined slightly in 2010 due primarily to non-recurring construction fee income earned in 2009. Rental income includes non-cash straight line rent adjustments totaling approximately ($5) in 2010 and ($452) in 2009 and amortization of acquired real estate leases and obligations totaling approximately ($34) in 2010 and $281 in 2009.

        Real estate taxes.    The increase in real estate taxes reflects 2010 and 2009 acquisitions partially offset by the effect of lower assessed values for certain of our properties.

        Utility expenses.    The increase in utility expenses primarily reflects the effects of 2010 and 2009 property acquisitions.

        Other operating expenses.    The increase in other operating expenses primarily reflects our 2010 and 2009 property acquisitions.

        Depreciation and amortization.    The increase in depreciation and amortization reflects the effect of our property acquisitions and the amortization of leasing costs incurred and improvements made to some of our properties during 2010 and 2009.

47

---

        Acquisition related costs.    The increase in acquisition related costs resulted from our increased acquisition activities in 2010.

        General and administrative.    The increase in general and administrative expense primarily reflects the effect of our property acquisitions and the difference between actual costs for legal, accounting, trustees fees, internal audit expenses, share grant awards and other administrative expenses compared to our allocation of general and administrative expense from CWH prior to our becoming a separate public company in June 2009.

        Interest income.    The increase in interest income is the result of our having a higher average amount of investable cash during the year ended December 31, 2010.

        Interest expense.    The increase in interest expense reflects larger outstanding borrowings under our revolving credit facilities compared to the same period in 2009 and interest expense related to the three mortgages we assumed in connection with certain of our 2010 acquisitions, partially offset by a lower weighted average interest rate for borrowings under our revolving credit facilities in 2010.

        Loss on extinguishment of debt.    The loss on extinguishment of debt is the result of our write off of remaining unamortized financing costs associated with our terminated initial $250,000 secured revolving credit facility.

        Equity in losses of investee.    The equity in losses of investee is our proportionate share of the losses as an investor in AIC.

        Income tax expense.    The increase in income tax expense is a result of our higher operating income in 2010 which is subject to state income taxes in certain jurisdictions.

        Net income and net income per Share.    Our net income for the year ended December 31, 2010 increased as compared to the year ended December 31, 2009 as a result of the changes noted above. On a per Share basis, the percentage increase in net income is lower due to our issuance of Shares in 2009 and 2010.

48

---

Year Ended December 31, 2009, Compared to Year Ended December 31, 2008

        Rental income.    The increase in rental income between 2009 and 2008 primarily reflects the effects of property acquisitions, rent increases from new leases and leases renewed during 2008 at our properties, net of one lease renewed at a rate lower than its historical rate. The increase also includes contractual expense reimbursements based upon changes in the consumer price index and changes in real estate tax expense. Rental income includes non-cash straight line rent adjustments totaling approximately ($452) in 2009 and ($249) in 2008 and amortization of acquired real estate leases and obligations totaling approximately $281 in 2009 and $352 in 2008.

        Real estate taxes.    The increase in real estate taxes reflects 2009 acquisitions and increases in both assessed values and tax rates for some of our properties.

        Utility expenses.    The increase in utility expenses is the result of our 2009 property acquisitions and also reflects utility rate and usage increases at some of our properties.

        Other operating expenses.    The increase in other operating expenses primarily reflects the increase in repairs and maintenance expense at our properties.

        Depreciation and amortization.    The increase in depreciation and amortization reflects depreciation related to acquisitions, the amortization of leasing costs incurred during 2009 and improvements made to some of our properties during 2009.

        Acquisition related costs.    The increase in acquisition costs reflects the costs associated with our acquisitions in August and December 2009. Prior to January 2009, such costs were capitalized into the total cost of acquiring a property.

49

---

        General and administrative.    The increase in general and administrative expense primarily reflects the increased costs for legal, accounting, trustees fees, internal audit expenses, share grant awards and other administrative expenses as a result of our becoming a separate public company.

        Interest income.    The increase in interest income is the result of our having a higher average amount of investable cash during the year ended December 31, 2009.

        Interest expense.    The increase in interest expense reflects our borrowing under our secured revolving credit facility for acquisitions, working capital and other business purposes. Interest expense for 2009 also includes $1,551 for the amortization of deferred financing fees. The deferred financing fees were incurred in connection with entering our secured revolving credit facility in April 2009.

        Equity in losses of investee.    The equity in losses of investee is our proportionate share of the losses as an investor in AIC.

        Income tax expense.    The increase in income tax expense reflects state taxes paid in 2009 as a result of our becoming a separate public company.

        Net income.    Our net income for the year ended December 31, 2009 decreased as compared to the year ended December 31, 2008 as a result of the changes noted above.

LIQUIDITY AND CAPITAL RESOURCES

Our Operating Liquidity and Resources (dollar amounts in thousands).

        Our principal source of funds to meet operating expenses and pay distributions on our Shares is rental income from our properties. We believe that our operating cash flow will be sufficient to pay our operating expenses, debt service and distributions on our Shares for the next twelve months and the foreseeable future after the next twelve months. Our future cash flows from operating activities will depend primarily upon our ability to:

•

maintain or increase the occupancy of, and the current rent rates at, our properties;



•

control operating cost increases at our properties; and



•

purchase additional properties which produce positive cash flows from operations.

        We generally do not intend to purchase "turn around" properties, or properties which do not generate positive cash flows. Our future purchases of properties which generate positive cash flow cannot be accurately projected because such purchases depend upon available opportunities which come to our attention.

        Our changes in cash flows in the year ended December 31, 2010 compared to the same period in 2009 was as follows: (i) cash flow provided by operating activities increased from $40,074 in 2009 to $59,149 in 2010; (ii) cash used in investment activities increased from $105,185 in 2009 to $394,693 in 2010; and (iii) cash provided by financing activities increased from $66,492 in 2009 to $336,503 in 2010.

        The increase in cash provided by operating activities between 2010 and 2009 is due primarily to cash flows from properties acquired after October 1, 2009, and changes in our working capital. The increase in cash used in investing activities between 2010 and 2009 is primarily due to our increased property acquisition activities in 2010. The increase in cash provided by financing activities between 2010 and 2009 is primarily due to an increase in proceeds from the issuances of approximately 19 million of our shares in 2010 as opposed to the issuance of approximately 11.5 million of our shares in 2009 in connection with our IPO; and the 2009 distribution to CWH prior to our IPO.

Our Investment and Financing Liquidity and Resources (dollar amounts in thousands, except per Share amounts).

        In order to fund acquisitions and to accommodate cash needs that may result from timing differences between our receipt of rents and our desire or need to make distributions or pay operating or capital expenses, we maintain our $500,000 unsecured revolving credit facility from a syndicate of financial institutions. This facility replaced our initial $250,000 secured revolving credit facility in October 2010. Our unsecured revolving credit facility matures on October 28, 2013 and we may extend the maturity date to October 28, 2014, subject to meeting certain conditions and payment of a fee. At December 31, 2010, there was $118,000 outstanding and $382,000 available for borrowings under our unsecured revolving credit facility, and we had cash and cash equivalents of $2,437. We expect to use cash balances, borrowings under our unsecured revolving credit facility and net proceeds from offerings of equity or debt securities to fund our future operations, distributions to our shareholders and any future property acquisitions.

        When significant amounts are outstanding under our unsecured revolving credit facility or the maturity date of that credit facility or our other debts approach, we intend to explore alternatives for repaying or refinancing such amounts. Such alternatives may include incurring term debt, issuing new equity securities, such as we did with our January 2010 and August 2010 equity offerings, or extending the maturity date of our unsecured revolving credit facility. Although there has recently been a significant reduction in the amount of capital available for real estate business on a global basis and we can provide no assurance that we will be successful in consummating any particular type of financing, we believe that we will have access to financing, such as debt and equity offerings, to fund future acquisitions and capital expenditures and to pay our obligations. We have an effective shelf registration statement that allows us to issue public securities on an expedited basis, but it does not assure that there will be buyers for such securities.

        Our ability to obtain, and the costs of, our future financings will depend primarily on market conditions and our creditworthiness. We have no control over market conditions. Potential investors and lenders likely will evaluate our ability to pay distributions to shareholders, fund required debt service and repay debts when they become due by reviewing our business practices and plans to balance our use of debt and equity capital so that our financial profile and leverage ratios afford us flexibility to withstand any reasonably anticipated adverse changes. We intend to conduct our business activities in a manner which will afford us reasonable access to capital for investment and financing activities, but there can be no assurance that we will be able to successfully carry out this intention.

        On January 28, 2010 and May 21, 2010, we paid a $0.40 per Share distribution to our common shareholders. On August 13, 2010, November 19, 2010 and February 23, 2011 we paid a $0.41 per Share distribution to our common shareholders, an increase of $0.01 per Share per quarterly period. We funded these distributions using existing cash balances and borrowings under our revolving credit facilities.

        During the years ended December 31, 2010 and 2009, cash expenditures made and capitalized at our properties for tenant improvements, leasing costs, building improvements and development and redevelopment activities were as follows:

        In connection with leasing space during the year ended December 31, 2010, we have committed to fund future expenditures as follows (dollars in thousands, except per square foot amounts):

        We have no commercial paper, swaps, hedges, real estate joint ventures or off balance sheet arrangements as of December 31, 2010. None of our debt documentation requires us to provide collateral security in the event of a ratings downgrade.

        As of December 31, 2010, our contractual obligations were as follows (dollars in thousands):

52

---

Debt Covenants (dollars in thousands)

        Our principal debt obligations at December 31, 2010 are our $500,000 unsecured revolving credit facility and three secured mortgage loans assumed in connection with three of our 2010 acquisitions. Our mortgage loans are non-recourse and do not contain any material financial covenants. Our unsecured revolving credit facility agreement contains a number of covenants which restrict our ability to incur debts in excess of calculated amounts, restrict our ability to make distributions under certain circumstances and generally require us to maintain certain financial ratios. Our unsecured revolving credit facility provides for acceleration of payment of all amounts outstanding upon the occurrence and continuation of certain events of default or upon a change of control, including a change in our management by RMR. We believe we were in compliance with all of our covenants under our unsecured revolving credit facility agreement at December 31, 2010.

Related Person Transactions

        We have adopted written Governance Guidelines which address, among other things, the consideration and approval of any related person transactions. Under our Governance Guidelines, we may not enter into any transaction in which any Trustee or executive officer, any member of the immediate family of any Trustee or executive officer or any other related person, has or will have a direct or indirect material interest unless that transaction has been disclosed or made known to our Board of Trustees and our Board of Trustees reviews, authorizes and approves or ratifies the transaction by the affirmative vote of a majority of the disinterested Trustees, even if the disinterested Trustees constitute less than a quorum. If there are no disinterested Trustees, the transaction shall be reviewed, authorized and approved or ratified by both (1) the affirmative vote of a majority of our entire Board of Trustees and (2) the affirmative vote of a majority of our Independent Trustees. Our Governance Guidelines further provide that, in determining whether to approve or ratify a transaction, our Board of Trustees, or disinterested Trustees or Independent Trustees, as the case may be, shall act in accordance with any applicable provisions of our declaration of trust, consider all of the relevant facts and circumstances, and approve only those transactions that are fair and reasonable to us. All related person transactions described below were reviewed and approved or ratified by a majority of the disinterested Trustees or otherwise in accordance with our policies described above. In the case of any transaction with us in which any other employee of ours who is subject to our Code of Conduct and who has a direct or indirect material interest in the transaction, the employee must seek approval from an executive officer who has no interest in the matter for which approval is being requested.

        We have two agreements with RMR to provide management and administrative services to us: a business management agreement and a property management agreement. One of our Managing Trustees, Mr. Barry Portnoy, is Chairman and majority owner of RMR. Our other Managing Trustee, Mr. Adam Portnoy, the son of Mr. Barry Portnoy, is an owner, President, Chief Executive Officer and a Director of RMR. Additionally, Mr. Barry Portnoy's son-in-law, who is Mr. Adam Portnoy's brother-in-law, is an officer of RMR. Our executive officers are also officers of RMR. RMR has approximately 650 employees and provides management services to other companies in addition to us, and an affiliate of RMR is a registered investment advisor that manages two mutual funds.

        Our Board of Trustees has given our Compensation Committee, which is comprised exclusively of our Independent Trustees, authority to act with respect to our management agreements with RMR. The charter of our Compensation Committee requires the Committee annually to review the terms of the agreements, evaluate RMR's performance under the agreements and renew, amend, terminate or allow to expire the management agreements.

        The business management agreement provides for compensation to RMR at an annual rate equal to the sum of (a) 0.5% of the historical cost to CWH of any properties transferred to us by CWH and (b) 0.7% of our cost of any other properties we acquire up to and including $250 million, plus 0.5% of our cost of any additional properties in excess of $250 million. In addition, RMR receives an incentive fee based upon increases in our FFO Per Share, as defined in the business management agreement, commencing with our fiscal year ending December 31, 2010. The incentive fee is paid in our common shares. The property management agreement provides for management fees equal to 3.0% of gross rents and construction supervision fees equal to 5.0% of construction costs. The aggregate business management and property management fees for 2010 were $8.2 million The aggregate business management and property management fees for 2009 were $5.6 million, which includes $2.4 million of the fees payable to RMR by CWH that were allocated to us by CWH before we became a separate company. The aggregate business management and property management fees for 2008 payable to RMR by CWH that were allocated to us by CWH before we became a separate company were $4.8 million. No incentive fees were earned by RMR in 2010.

        RMR also provides internal audit services to us in return for our pro rata share of the total internal audit costs incurred by RMR for us and other companies managed by RMR and its affiliates, which amounts are subject to determination by our Compensation Committee. Our Audit Committee appoints our Director of Internal Audit. Our pro rata share of RMR's costs in providing this internal audit function was approximately $211,000 and $121,000 for 2010 and 2009, respectively. These allocated costs are in addition to the business and property management fees we paid to RMR. We are generally responsible for all of our operating expenses, including certain expenses incurred by RMR on our behalf. We are not responsible for payment of RMR's employment, office or administration expenses incurred to provide management services to us, except for our pro rata share of the employment and related expenses of RMR employees who provide on-site property management services and of the staff employed by RMR who perform our internal audit function.

        Both the business management agreement and the property management agreement automatically renew for successive one year terms unless we or RMR give notice of non-renewal before the end of an applicable term. We or RMR may terminate either agreement upon 60 days prior written notice and RMR may also terminate either agreement upon five business days notice if we undergo a change of control, as defined in the applicable agreement. The current terms for these agreements expire on December 31, 2011, and they will automatically renew unless earlier terminated.

        Under our business management agreement with RMR, we acknowledge that RMR manages other businesses, including CWH, HPT, SNH, TA and FVE, and will not be required to present us with opportunities to invest in properties that are primarily of a type that are within the investment focus of another business now or in the future managed by RMR. Under our business management agreement, RMR has agreed not to present other businesses that it now or in the future manages with opportunities to invest in properties that are majority leased to government tenants unless our Independent Trustees have determined not to invest in the opportunity. RMR has also agreed not to provide business management services to any other business which is principally engaged in the business of owning properties which are majority leased or occupied to Governmental Authorities, as defined in the business management agreement, or which are reasonably expected to be majority leased to Governmental Authorities, without the consent of our Independent Trustees. Each of the business management agreement and the property management agreement also includes arbitration provisions for the resolution of disputes, claims and controversies.

        RMR also leases from us approximately 1,400 square feet of office space for a regional office. We earned approximately $14,000 in rental income from RMR in 2010, which we believe is a commercially reasonable rate for such office space.

        Pursuant to our business management agreement, RMR may from time to time negotiate on our behalf with third party vendors and suppliers for the procurement of services to us. As part of this arrangement, we may enter agreements with RMR and other companies to which RMR provides management services for the purpose of obtaining more favorable terms from such vendors and suppliers.

        As part of our annual restricted share grants under our share award plan adopted in 2009, or the 2009 Plan, we typically grant restricted shares to certain employees of RMR, some of whom are our executive officers. In 2010, we granted a total of 36,950 restricted shares to such persons, which had an aggregate value of $984,718 based upon the closing price of our Shares on the NYSE on the date of grant. One fifth of those restricted shares vested on the grant date and one fifth vests on each of the next four anniversaries of the grant date. These share grants to RMR employees are in addition to the fees we pay to RMR.

        CWH organized us as a 100% owned subsidiary in February 2009. In June 2009, we completed our IPO pursuant to which we ceased to be a subsidiary of CWH. In connection with this offering, we and CWH entered the transaction agreement, which governs our separation from and relationship with CWH. Pursuant to the transaction agreement, among other things:

•

We agreed to indemnify CWH with respect to any liability relating to the 29 properties CWH transferred to us prior to our IPO, including liabilities which arose before our formation.



•

We and CWH agreed that, so long as CWH owns in excess of 10% of our outstanding Shares, we and CWH engage the same manager or we and CWH have any common managing trustees, (1) CWH will not acquire ownership of properties which are majority leased to government tenants, unless a majority of our Independent Trustees who are not also Trustees of CWH have determined not to make the acquisition, (2) we will not acquire ownership of office or industrial properties which are not majority leased to government tenants, unless a majority of CWH's Independent Trustees who are not also Trustees of ours have determined not to make the acquisition, and (3) we will have a right of first refusal to purchase any property owned by CWH that CWH determines to divest if the property is then majority leased to government tenants, which right of first refusal will also apply in the event of an indirect sale of any such properties resulting from a change of control of CWH. The provisions described in (1) and (2) do not prevent us from continuing to own and lease our current properties or properties otherwise acquired by us that cease to be majority leased to government tenants following the termination of government tenancies; and, similarly, the provisions described in (1) and (2) also do not prohibit CWH from leasing its current or future properties to government tenants.



•

We and CWH agreed that certain disputes, claims and controversies arising under the transaction agreement may be referred to binding arbitration proceedings.

        In June 2010, we entered into a series of agreements to purchase from CWH 15 properties which are majority leased to government tenants that included approximately 1.9 million rentable square feet. We completed the purchase of all 15 of these properties in 2010 for an aggregate purchase price of $231.0 million, excluding acquisition costs. These 15 properties were subject to the right of first refusal CWH granted to us in the transaction agreement described above. These purchase agreements with CWH include arbitration provisions for the resolution of disputes, claims and controversies.

        As of February 24, 2011, CWH owned 9,950,000 of our Shares, which represented approximately 24.6% of our outstanding Shares. Both we and CWH are managed by RMR, and Barry Portnoy and Adam Portnoy are Managing Trustees of both us and CWH. Adam Portnoy was also our President from our formation in 2009 until January 2011 when David Blackman became our President. Adam Portnoy became President of CWH in January 2011. Also, all of our officers and CWH's officers are officers of RMR. Accordingly, the purchase agreements between us and CWH described above which

55

---

were entered after we became a separate public company were negotiated and approved by special committees of each company's board of trustees, comprised solely of Independent Trustees who are not also Independent Trustees of the other party to these agreements.

        Our Independent Trustees also serve as directors or trustees of other public companies to which RMR provides management services. Mr. Barry Portnoy serves as a managing director or managing trustee of those companies, including CWH, HPT, SNH, FVE and TA, and Mr. Adam Portnoy serves as a managing trustee of some of those companies, including CWH, HPT and SNH. We understand that the other companies to which RMR provides management services also have relationships with each other, including business and property management agreements and lease arrangements. In addition, officers of RMR serve as officers of those companies. Mr. Kleifges, our Treasurer and Chief Financial Officer, also serves as Treasurer and Chief Financial Officer of HPT and is an officer of RMR. We understand that further information regarding those relationships is provided in the applicable periodic reports and proxy statements filed by those other companies with the SEC.

        We, RMR, CWH, HPT, SNH, FVE and TA each currently own 14.29% of AIC, an Indiana insurance company. All of our Trustees and nearly all of the trustees and directors of the other AIC shareholders currently serve on the board of directors of AIC. RMR, in addition to being a shareholder, provides management and administrative services to AIC pursuant to a management and administrative services agreement with AIC. Our Governance Guidelines provide that any material transaction between us and AIC shall be reviewed, authorized and approved or ratified by both the affirmative vote of a majority of our entire Board of Trustees and the affirmative vote of a majority of our Independent Trustees. The shareholders agreement among us, the other shareholders of AIC and AIC includes arbitration provisions for the resolution of disputes, claims and controversies.

        As of February 24, 2011, we have invested approximately $5,194,000 in AIC since we became an equity owner of AIC in December 2009. We may invest additional amounts in AIC in the future if the expansion of this insurance business requires additional capital, but we are not obligated to do so. For 2010 and 2009, we recognized income (loss) of $(771) and ($14,565), respectively, related to our investment in AIC. In 2010, AIC designed a combination property insurance program for us and other AIC shareholders in which AIC participated as a reinsurer. Our total premiums paid under this program in 2010 were approximately $415,000. We are currently investigating the possibilities to expand our insurance relationships with AIC to include other types of insurance. By participating in this insurance business with RMR and the other companies to which RMR provides management services, we expect that we may benefit financially by possibly reducing our insurance expenses or by realizing our pro-rata share of any profits of this insurance business.

        The foregoing descriptions of our agreements with RMR, CWH and AIC and various individuals and companies related to us and them are summaries and are qualified in their entirety by the terms of the agreements which are among the exhibits listed in Item 15 of this Annual Report on Form 10-K and incorporated herein by reference. In addition, copies of certain of those agreements are filed with the SEC and may be obtained from the SEC's website at www.sec.gov.

        We believe that our agreements with RMR, CWH and AIC are on commercially reasonable terms. We also believe that our relationships with RMR, CWH, AIC and their affiliated and related persons and entities benefit us, and, in fact, provide us with advantages in operating and growing our business.

Critical Accounting Policies

        Our critical accounting policies are those that will have the most impact on the reporting of our financial condition and results of operations and those requiring significant judgments and estimates. We believe that our judgments and estimates are consistently applied and produce financial information

56

---

that fairly presents our results of operations. Our most critical accounting policies involve our investments in real property. These policies affect our:

•

allocation of purchase prices among various asset categories and the related impact on the recognition of rental income and depreciation and amortization expenses; and



•

assessment of the carrying values and impairments of long lived assets.

        We allocate the acquisition cost of each property investment to various property components such as land, buildings and improvements and intangibles based on their fair values, and each component generally has a different useful life. For real estate acquired, we record building, land and improvements, and, if applicable, the value of in-place leases, the fair market value of above or below market leases and customer relationships at fair value. We allocate the excess, if any, of the consideration over the fair value of assets acquired to goodwill. We base purchase price allocations and the determination of useful lives on our estimates and, under some circumstances, studies from independent real estate appraisal firms to provide market information and evaluations that are relevant to management's purchase price allocations and determinations of useful lives; however, management is ultimately responsible for the purchase price allocations and determination of useful lives.

        We compute depreciation expense using the straight line method over estimated useful lives of up to 40 years for buildings and improvements, and up to 12 years for personal property. We do not depreciate the allocated cost of land. We amortize capitalized above market lease values as a reduction to rental income over the terms of the respective leases. We amortize capitalized below market lease values as an increase to rental income over the terms of the respective leases. We amortize the value of in place leases exclusive of the value of above market and below market in place leases to expense over the periods of the respective leases. If a lease is terminated prior to its stated expiration, all unamortized amounts relating to that lease are written off. Purchase price allocations require us to make certain assumptions and estimates. Incorrect assumptions and estimates may result in inaccurate depreciation and amortization charges over future periods.

        We periodically evaluate our properties for impairment. Impairment indicators may include declining tenant occupancy or our decision to dispose of an asset before the end of its estimated useful life and legislative, market or industry changes that could permanently reduce the value of a property. If indicators of impairment are present, we evaluate the carrying value of the related property by comparing it to the expected future undiscounted cash flows to be generated from that property. If the sum of these expected future cash flows is less than the carrying value, we reduce the net carrying value of the property to its fair value. This analysis requires us to judge whether indicators of impairment exist and to estimate likely future cash flows. If we misjudge or estimate incorrectly or if future tenant operations, market or industry factors differ from our expectations we may record an impairment charge that is inappropriate or fail to record a charge when we should have done so, or the amount of any such charges may be inaccurate.

        These policies involve significant judgments made based upon experience, including judgments about current valuations, ultimate realizable value, estimated useful lives, salvage or residual value, the ability and willingness of our tenants to perform their obligations to us, current and future economic conditions and competitive factors in the markets in which our properties are located. Competition, economic conditions, changing government priorities and other factors may cause occupancy declines in the future. In the future, we may need to revise our carrying value assessments to incorporate information which is not now known, and such revisions could increase or decrease our depreciation expense related to properties we own or decrease the carrying values of our assets.

Impact of Inflation

        Inflation might have both positive and negative impacts upon us. Inflation might cause the value of our real estate to increase. Inflation might also cause our costs of equity and debt capital and operating costs to increase. An increase in our capital costs or in our operating costs will result in decreased earnings unless it is offset by increased revenues. Our government leases generally provide for annual rent increases based on a cost of living index calculation which should offset any increased costs as a result of inflation.

        To mitigate the adverse impact of any increased cost of debt capital in the event of material inflation, we may enter into interest rate hedge arrangements in the future, but we have no present intention to do so. The decision to enter into these agreements will be based on the amount of our floating rate debt outstanding, our belief that material interest rate increases are likely to occur and upon requirements of our borrowing arrangements.

Impact of Climate Change

        The current political debate about climate change has resulted in various existing and proposed treaties, laws and regulations which are intended to limit carbon emissions. We believe such treaties, laws and regulations being enacted or proposed may cause energy costs at our properties to increase, but we do not expect the direct impact of these increases to be material to our results of operations because the increased costs either would be the responsibility of our tenants directly or in large part may be passed through by us to our tenants as additional lease payments. Although we do not believe it is likely in the foreseeable future, laws enacted to mitigate climate change may make some of our buildings obsolete or cause us to make material investments in our properties which could materially and adversely affect our financial condition and results of operations.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk (dollar amounts in thousands)

        We are exposed to risks associated with market changes in interest rates. We manage our exposure to this market risk by monitoring available financing alternatives. Other than as described below, we do not foresee any significant changes in our exposure to fluctuations in interest rates or in how we manage this exposure in the near future.

        At December 31, 2010, our outstanding fixed rate debt included the following:

        Because these debts bear interest at a fixed rate, changes in market interest rates during the term of these debts will not affect our operating results. If these debts are refinanced at interest rates which are 10% higher or lower than shown above, our per annum interest cost would increase or decrease by approximately $304. Changes in market interest rates also affect the fair value of our fixed rate debt obligations; increases in market interest rates decrease the fair value of our fixed rate debt, while decreases in market interest rates increase the fair value of our fixed rate debt. Based on the balances outstanding at December 31, 2010, and discounted cash flow analysis through the maturity date of our fixed rate debt obligations, a hypothetical immediate 10% change in interest rates would change the fair value of those obligations by approximately $1,216.

        As of December 31, 2010, we had $118,000 drawn and $382,000 available under our unsecured revolving credit facility. Our unsecured revolving credit facility matures on October 28, 2013, and subject to meeting certain conditions and the payment of a fee, we may extend the facility for one year to October 28, 2014. We may make repayments and drawings under our unsecured revolving credit facility at any time without penalty. Borrowings under our unsecured revolving credit facility are in U.S. dollars and will accrue interest at LIBOR plus a spread which varies depending on the amount of our debt leverage or our credit ratings. In addition, upon renewal or refinancing of our unsecured revolving credit facility, we are vulnerable to increases in credit spreads due to market conditions. A change in interest rates generally would not affect the value of our floating rate debt but would affect our operating results. For example, the interest rate payable on our unsecured revolving credit facility at December 31, 2010 was 2.37%. The following table presents the impact a 10% change in interest rates would have on our annual floating rate interest expense at December 31, 2010:
