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. We were organized to concentrate the ownership of certain CWH properties that were majority leased to government tenants and to expand such investments. In June 2009, we completed our initial public offering, or IPO. CWH currently owns 18.2% of our outstanding common shares.

As of December 31, 2012, we owned 84 properties with an undepreciated carrying value, net of impairment losses, of approximately 1.5 billion, and a depreciated book value of $1.4 billion. These 84 properties have approximately 10.2 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 or enter into new leases as they expire, enter into new leases for our vacant space, 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 we would seek to be 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. Our historical experience, including that of our predecessor, CWH, with respect to properties of the type that we own that are majority leased to government tenants 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 regard 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 or when we have vacant space. 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 our 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. The U.S. Government and state and local governments lease significant amounts of office space. Additionally, we believe that budgetary pressures may cause an increased demand for leased space by government tenants, as opposed to new buildings built on behalf of government tenants. However, these same budgetary pressures could also result in a decrease in government sector employment and consolidation into government owned properties thereby reducing the demand for leased space. If the U.S. Government and state and local governments increase the amount of space that they lease, 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 property;

•: 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;
•: the construction quality, physical condition and design of the property and expected capital expenditures that may be needed to be made to 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.

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 from our properties than in 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 (excluding capital gains) 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. In addition, we may assume outstanding mortgage debt on properties we acquire. We currently have a $550.0 million unsecured revolving credit facility, or our revolving credit facility, which is guaranteed by most of our subsidiaries, that we use for working capital and general business purposes and to fund the acquisition of properties. As we have utilized our revolving credit facility, we have refinanced or reduced amounts outstanding under this facility with term debt or equity issuances and we expect to continue this practice in the future. 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 cannot assure that we will be able to raise sufficient capital to repay our debt or to fund our growth strategy.

We have not in the past, but we may in the future, invest in the securities of other issuers for the purpose 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.

Although there are no limitations in our organizational documents on the amount of indebtedness we may incur, the borrowing limitations established by the covenants in our revolving credit facility and our five year $350 million unsecured term loan, or our term loan, prohibit us from maintaining a debt to total asset value, as defined, of greater than 60%. We currently intend to pursue our growth strategy

while limiting our debt to no more than 50% of our total book capitalization. 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) 796-8390. RMR also acts as the manager to CWH, Hospitality Properties Trust, or HPT, Senior Housing Properties Trust, or SNH, and Select Income REIT, or SIR, and provides management and other services to other private and public companies, including Five Star Quality Care, Inc., or FVE, TravelCenters of America LLC, or TA, and Sonesta International Hotels Corporation, or Sonesta. Barry M. Portnoy is the Chairman of RMR, and its other directors are Adam D. Portnoy, Gerard M. Martin and David J. Hegarty. As of the date of this Annual Report on Form 10-K, 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; Bruce J. Mackey Jr., Executive Vice President; John G. Murray, Executive Vice President; Thomas M. O'Brien, Executive Vice President; John C. Popeo, Executive Vice President; William J. Sheehan, Executive Vice President; David M. Blackman, Senior Vice President; Ethan S. Bornstein, Senior Vice President; Richard A. Doyle, Senior Vice President; Paul V. Hoagland, Senior Vice President; Matthew P. Jordan, Senior Vice President, Treasurer and Chief Financial Officer; David M. Lepore, Senior Vice President; Andrew J. Rebholz, Senior Vice President; and Mark R. Young, Senior Vice President. David M. Blackman and Mark L. Kleifges are also our executive officers. Mr. Adam Portnoy was also our President from our formation in 2009 until January 2011 when David Blackman became our President. Messrs. Blackman and 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 21, 2013, RMR had approximately 820 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 highly 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. Some of our competitors are dominant in selected geographic markets, including in markets in which we operate. Some of our competitors may have greater financial and management 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 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 more information see "Risk Factors—Risks Related to Our Business—We face significant competition."

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 removed the asbestos or demolished these properties, certain environmental regulations govern the manner in which the asbestos must be handled and removed, and we could incur substantial costs complying with such regulations. 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, we cannot assure 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. The current political debate about climate change has resulted in various treaties, laws and regulations which are intended to limit carbon emissions. We believe these laws being enacted or proposed may cause energy costs at our properties to increase. 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. For more information, see "Risk Factors—Risks Related to Our Business—Ownership of real estate is subject to environmental and climate change risks" and for more information regarding climate change matters and their possible adverse impact on us, please see "Management's Discussion and Analysis of Financial Condition and Results of Operations—Environmental and Climate Change Matters."

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. The Energy Independence and Security Act of 2007 also allows the General Services Administration, or GSA, to give preference to buildings for lease that have received an "Energy Star" label. The Energy Star Partner program is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy which is focused on promoting energy efficiency and sustainability at commercial properties. Buildings that reach a specified level of energy efficiency may receive the Energy Star label. We have received ratings for many of our buildings, and 40 of our buildings with combined 5,737,597 rentable square feet (47.1% and 56.2% or our total buildings and total rentable square feet, respectively) have qualified for Energy Star labels.

The U.S. Government's "green lease" initiative also permits government tenants to require leadership in energy and environmental design, or LEED®, certification in selecting new premises or renewing leases at existing premises. The LEED® certification program is administered by the U.S. Green Building Council, a nonprofit organization focused on promoting energy efficiency at commercial properties. Buildings that reach a specified level of energy efficiency may receive a LEED® certificate. We have received LEED® certificates for 6 of our buildings with combined rentable square feet (7.1% and 6.8% or our total buildings and total rentable square feet, respectively).

We and our manager, RMR, continuously study ways to improve the energy efficiency at our properties. RMR is also a member of the Energy Star Partner program and a member of the U.S. Green Building Council. However, obtaining additional Energy Star labels and/or a LEED® certificates at our properties may be costly and time consuming, and we have not yet determined whether it will make economic sense to do so. For more information, see "Risk Factors—Risks Related to Our Business—The U.S. Government's "green lease" policies may adversely affect us."

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, insurance company, regulated investment company, REIT 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 sections of the IRC 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 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 are urged to consult their tax advisors about the federal income tax consequences of the acquisition, ownership and disposition of our shares.

Taxation as a REIT

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, will continue 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. 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, which we refer to as 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.

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 preferential tax rates on qualified dividend income, but a portion of our

dividends may be treated as capital gain dividends or qualified dividend income, 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 returns 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, of which there are none outstanding at this time, 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 provided to us an opinion that we have been organized and have qualified as a REIT under the IRC for our 2009 through 2012 taxable years, and that our current investments and plan of operation will enable us to continue to meet the requirements for qualification and taxation as a REIT under the IRC. Our counsel's opinions are conditioned upon the assumption that our leases, our declaration of trust and all other legal documents to which we are or have been a party have been and will be complied with by all parties to those documents, upon the accuracy and completeness of the factual matters described in this Annual Report on Form 10-K and upon representations made by us as to certain factual matters relating to our organization and operations and our expected manner of operation. If this assumption or a representation is inaccurate or incomplete, our counsel's opinions may be adversely affected and may not be relied upon. The opinions of our tax counsel are based upon the law as it exists today, but the law may change in the future, possibly with retroactive effect. Given the highly complex nature of the rules governing REITs, the ongoing importance of factual determinations, and the possibility of future changes in our circumstances, no assurance can be given by Sullivan & Worcester LLP or us that we will qualify as or be taxed as a REIT for any particular year. Any opinion of Sullivan & Worcester LLP as to our qualification or taxation as a REIT will be expressed as of the date issued. Our counsel will have no obligation to advise us or our shareholders of any subsequent change in the matters stated, represented or assumed or of any subsequent change in the applicable law. Also, the opinions of tax counsel are not binding on either the IRS or a court, and either could take a position different from that expressed by tax counsel.

Our continued qualification and taxation as a REIT will depend upon our compliance on a continuing basis 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 in any year, we will be subject to federal income taxation as if we were a corporation taxed under subchapter C of the IRC, or a C corporation, and our shareholders will be taxed like shareholders of C corporations, meaning that federal income tax generally will be applied at both the corporate and shareholder levels. 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—that is, dispositions of inventory or property held primarily for sale to customers in the ordinary course of business other than dispositions of foreclosure property and other than dispositions excepted under a statutory safe harbor—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, 10 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 in a transaction where we succeed to its tax attributes, 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 our taxable year in which the acquisition occurs. 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 all of our taxable income to our shareholders such that 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, then we will be subject to federal income tax in the same manner as a regular C corporation. Further, as a regular C corporation, distributions to our shareholders will not be deductible by us, nor will distributions be required under the IRC. Also, to the extent of our current and accumulated earnings and profits, all distributions to our shareholders will generally be taxable as ordinary dividends potentially eligible for preferential tax rates 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. Finally, we will generally be disqualified from qualification as a REIT for the four taxable years following disqualification. Our failure to qualify as a

REIT for even one year 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 will 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 (except for our first taxable year as a REIT) 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 that would otherwise result in concentrated ownership positions. 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 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 entities that are treated as partnerships for federal income tax purposes, including limited or general partnerships, limited liability companies, or foreign entities. 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 retains 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 the total value 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 of ours 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, on a continuous basis, the requirements for taxable REIT subsidiary status at all times during which the subsidiary's taxable REIT subsidiary election is reported as being 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, and if the REIT has not adequately compensated the taxable REIT subsidiary for services provided to or on behalf of a tenant, then the REIT may be subject to an excise tax equal to 100% of the undercompensation to the taxable REIT subsidiary. 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 transactions that we enter into to manage interest rate or price changes or currency 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 (or any property that generates such income or gain); (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, gain from the sale or other

disposition of real property other than dealer 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 changes or currency 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 (or any property that generates such income or gain); (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 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 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, leasing and managing our existing properties and acquiring, developing, owning, leasing 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 amount by which we failed 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 year prior to the taxable year in which the failure was discovered.

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 the securities are "straight debt" securities or otherwise excepted as discussed below. Our stock and securities in a taxable REIT subsidiary are exempted from these 5% and 10% asset tests.
•: No more than 25% of our total assets may be represented by stock or securities of taxable REIT subsidiaries.

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 year prior to the taxable year in which the failure was discovered.

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 or within the six month periods described above.

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 federal income 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 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 federal income 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 depreciable 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, 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 perform and will perform all our tax reporting accordingly. This opinion was conditioned upon the assumption that the transaction agreement governing our separation 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; (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 that 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 any sale-leaseback arrangements, the IRS could assert that we realized or will 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 or exceeded the purchase price for that property. While we believe that the value of leased property at the time of any such purchase will or did 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

For noncorporate U.S. shareholders, to the extent that their total adjusted income does not exceed applicable thresholds, the maximum federal income tax rate for long-term capital gains and most corporate dividends is generally 15%. For those noncorporate U.S. shareholders whose total adjusted income exceeds such income thresholds, the maximum federal income tax rate for long-term capital gains and most corporate dividends is generally 20%. However, because we are not generally subject to federal income tax on the portion of our REIT taxable income distributed to our shareholders, dividends on our shares generally are not eligible for such preferential tax rates. As a result, our ordinary dividends continue to be taxed at the higher federal income tax rates applicable to ordinary income. However, the preferential federal income tax rates for long-term capital gains and for dividends generally apply to:

(1): 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 C 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.

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 generally 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.

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 preferential maximum rates (including any capital gains attributable to real estate depreciation recapture that are subject to a maximum 25% federal income tax rate) 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 preferential maximum rates. No U.S. shareholder may include on his federal income tax return any of our net operating losses or any of our capital losses.

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. shareholders who are individuals, estates or trusts are generally 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. For unmarried individuals, estates and trusts, the threshold is $200,000; for married individuals filing jointly, the threshold is $250,000; and for married individuals filing separately, the threshold is $125,000.

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 and qualified dividends 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

Subject to the pension-held REIT rules discussed below, 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 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 become 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 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 as 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, as well as 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) these dividends are received with respect to a class of shares that is "regularly traded" on a domestic "established securities market" such as the New York Stock Exchange, or 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 applicable capital gain and United States real property interest dividends. If both of these provisions are satisfied, qualifying non-U.S. shareholders will not be subject to withholding either on capital gain dividends or on dividends that are attributable to our sales of United States real property interests 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 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 and other tax rates applicable to a U.S. shareholder, subject to any applicable alternative minimum tax and to a 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. A non-U.S. shareholder 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 higher than the current preferential 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.

Non-U.S. shareholders should generally be able to treat amounts we designate as retained but constructively distributed capital gains in the same manner as actual distributions of capital gain dividends by us. In addition, a non-U.S. shareholder should be able to offset as a credit against its

federal income tax liability the proportionate share of the tax paid by us on such retained but constructively distributed capital gains. A non-U.S. shareholder may file for a refund from the IRS for the amount that the non-U.S. shareholder's proportionate share of tax paid by us exceeds its federal income tax liability on the constructively distributed capital gains.

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%. 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, 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.

Increased reporting obligations are scheduled to be imposed on 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. 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 nonfinancial 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. Pursuant to Treasury regulations, such withholding applies only to dividends paid on or after January 1, 2014, and to other "withholdable payments" (including payments of gross proceeds from a sale or other disposition of our shares) made on or after January 1, 2017. 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 Congress, the IRS and the United States Treasury, 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.

ERISA PLANS, KEOGH PLANS AND INDIVIDUAL RETIREMENT ACCOUNTS

General Fiduciary Obligations

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 individual retirement account or annuity, or 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 United States Department of Labor 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 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 have been 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 that 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 that 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 that 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 that 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 that 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 that 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 our 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 acquires our shares in a public offering. This opinion is conditioned upon certain assumptions and representations, as discussed above in "Federal Income Tax Considerations—Taxation as a REIT."

Item 1A. Risk Factors

Our business faces many risks. The risks described below may not be the only risks we face, but are the risks we know of that we believe may be material at this time. 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, 2012 is 5.5 years based upon annual rental income and 5.5 years based upon occupied square footage. As of December 31, 2012, leases representing approximately 55.7% of our rental income and 54.5% of our occupied square footage will expire by December 31, 2018. Although we typically will seek to renew our leases with current tenants when these leases expire, we cannot assure that we will be successful in doing so. If our tenants do not renew their leases, we may be unable to enter new 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 currently receive. 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.

When we lease to new tenants or renew leases we may have to spend substantial amounts for leasing commissions, tenant improvements or other tenant inducements. Many of our leases are for properties that are specially suited to the particular business of our tenants. Because these properties have been designed or physically modified for a particular tenant, if the current lease is terminated or not renewed, we may be required to renovate the property at substantial costs, decrease the rent we charge or provide other concessions in order to lease the property to another tenant.

We may be unable to acquire additional properties and grow our business and we cannot assure that acquisitions we make will prove to be successful.

An element of our business plan involves the acquisition of 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 properties that are not leased when acquired. Accordingly, we cannot assure that our business plan to acquire additional properties that are majority leased to government tenants will succeed.

We might encounter unanticipated difficulties and expenditures relating to any acquired properties. Newly acquired properties might require significant management attention that would otherwise be devoted to our ongoing business. We might never realize the anticipated benefits of our acquisitions. 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 costs for acquisitions may be higher than we anticipate and acquisitions of properties 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 business plan to acquire additional properties may not succeed or may cause us losses.

We may be unable to access the capital necessary to repay our 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 our 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 acquisitions. Because of the volatility in the availability of capital to business on a global basis and the increased volatility in most debt and equity markets generally, 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 conditions. If we are unable to raise reasonably priced capital, our business and growth strategies may fail and we may be unable to remain a REIT.

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 we consider appropriate and have sufficient available financing to complete the acquisition. We face significant competition for acquisition opportunities from other investors, including publicly traded and private REITs, numerous financial institutions, individuals and public and private companies. Because of competition, we may be unable to, or may pay a significantly increased purchase price to, acquire a desired property. Some of our competitors may have greater financial and management resources than we have.

In addition, substantially all of our properties face competition for tenants. Some competing properties may be newer, better located or more attractive to tenants. Competing properties may have lower rates of occupancy than our properties, which may result in competing owners offering 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.

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 LEED® 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 give preference to 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.

Some government tenants have the right to terminate their leases prior to their lease expiration date and changes in the government's requirements for leased space may adversely affect us.

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 8.6% of our rentable square feet and contributing approximately 7.1% of our annualized rental income as of December 31, 2012 have currently exercisable rights to terminate their leases before the stated term of their leases expire.
•: In 2013, 2014, 2015, 2016, 2017, 2018, 2019 and 2020, early termination rights become exercisable by other tenants who currently occupy an additional approximately 3.5%, 3.9%, 0.6%, 6.4%, 2.4%, 1.1%, 3.6% and 0.6% of our rentable square feet, respectively, and contribute an additional approximately 3.0%, 4.4%, 0.5%, 9.5%, 3.4%, 1.4%, 4.2% and 0.7% of our annualized rental income, respectively, as of December 31, 2012.
•: Pursuant to 12 leases with six of our state government tenants, these tenants have currently exercisable rights to terminate their leases if these states do not appropriate rent amounts in their respective annual budgets. These 12 leases represent approximately 7.6% of our rentable square feet and 7.6% of our annualized rental income as of December 31, 2012.

For fiscal policy reasons, security concerns or other reasons, some or all of our government tenants may decide to exercise early termination rights under our leases or vacate our properties upon expiration of our leases. Government agencies have been seeking to increase their space utilization under their leases, including reducing the amount of square footage per employee at leased properties, which may reduce the demand for government leased space. If a significant number of such events occur, our income and cash flow may materially decline and our ability to make regular distributions to our shareholders may be jeopardized.

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

Approximately 21.7% of our annualized rental income as of December 31, 2012 was received from properties located in the Washington, D.C. 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 or terminate and renewal or new terms are negotiated. Additionally, in the past year there has been a decrease in demand for new leased space by the U.S. Government in the Washington, D.C. metro area, and that could increase the competition for tenants and adversely affect our ability to retain our government tenants when our leases expire.

Our failure or inability to meet certain terms of our revolving credit facility or term loan agreements would adversely affect our business and may prevent us from making distributions to our shareholders.

Our revolving credit facility agreement includes various conditions to our borrowing and our revolving credit facility and term loan agreements include 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 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 revolving credit facility or term loan agreements at a time when borrowed amounts are outstanding under these instruments, our lenders may demand immediate payment, and if we default under our credit facility, our lenders may elect to not make further borrowings available to us.

Any default under our revolving credit facility or term loan agreements would likely have serious and adverse consequences to us and would likely cause the market price of our shares to materially decline and may prevent our making distributions to our shareholders.

In the future, we may obtain additional debt financing, and the covenants and conditions which apply to any such additional indebtedness may be more restrictive than the covenants and conditions contained in our revolving credit facility and term loan agreements.

We have substantial debt obligations and may incur additional debt.

As of December 31, 2012, we had $492.6 million in debt outstanding, which was 32.4% of our total book capitalization. Our revolving credit facility and term loan agreements permit us and our subsidiaries to incur additional debt, including secured debt. If we default in paying any of our debts or honoring our debt covenants, it may create one or more cross defaults, our debts may be accelerated and we could be forced to liquidate our assets for less than the values we would receive in a more orderly process.

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 or otherwise.

Increasing interest rates may adversely affect us and the value of an investment in our shares.

Interest rates are currently at historically low levels and may increase. Increasing interest rates may adversely affect us and the value of an investment in our shares, including in the following ways:

•: Amounts outstanding under our revolving credit facility and term loan bear interest at variable interest rates. When 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 make or sustain distributions to our shareholders. Additionally, if we choose to hedge our interest rate risk, we cannot assure that the hedge will be effective or that our hedging counterparty will meet its obligations to us.
•: 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. Further, increased interest rates may effectively increase the cost of properties we acquire to the extent we utilize leverage for those acquisitions and may result in a reduction in our acquisitions to the extent we reduce the amount we offer to pay for properties, due to the effect of increased interest rates, to a price that sellers may not accept.
•: We expect to make regular distributions to our shareholders. 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.

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

Ownership of real estate is subject to risks associated with environmental hazards. We may be liable for environmental hazards at, or migrating from, 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 at, or migrating from, properties they own or occupy, and we cannot assure that we will not be held liable for environmental investigation and clean up at, or near, 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, or migrating from, our properties. Moreover, the costs and damages which may arise from environmental hazards are often difficult to project and may be substantial.

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 removed the asbestos or demolished these properties, certain environmental regulations govern the manner in which the asbestos must be handled and removed, and we could incur substantial costs complying with such regulations.

Real estate ownership creates risks and liabilities.

In addition to the risks related to environmental hazards and climate change, our business is subject to other risks associated with real estate ownership, including:

•: the illiquid nature of real estate markets, which limits our ability to sell our assets rapidly to respond to changing market conditions;
•: the subjectivity of real estate valuations and changes in such valuations over time;
•: property and casualty losses;
•: 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;
•: legislative and regulatory developments that may occur at the federal, state and local levels that have direct or indirect impact on the ownership, leasing and operation of our properties; and
•: litigation incidental to our business.

We rely on information technology in our operations, and any material failure, inadequacy, interruption or security failure of that technology could harm our business.

We rely on information technology networks and systems, including the Internet, to process, transmit and store electronic information and to manage or support a variety of our business processes, including financial transactions and maintenance of records, which may include personal identifying information of tenants and lease data. We rely on commercially available systems, software, tools and monitoring to provide security for processing, transmitting and storing confidential tenant information, such as individually identifiable information relating to financial accounts. Although we have taken steps to protect the security of the data maintained in our information systems, it is possible that our security measures will not be able to prevent the systems' improper functioning, or the improper disclosure of personally identifiable information such as in the event of cyber attacks. Security breaches, including physical or electronic break-ins, computer viruses, attacks by hackers and similar breaches, can create system disruptions, shutdowns or unauthorized disclosure of confidential information. Any failure to maintain proper function, security and availability of our information systems could interrupt our operations, damage our reputation, subject us to liability claims or regulatory penalties and could materially and adversely affect us.

Changes in lease accounting standards may materially and adversely affect us.

The Financial Accounting Standards Board has proposed accounting rules that would require companies to capitalize all leases on their balance sheets by recognizing a lessee's rights and obligations. If the proposal is adopted in its current form, many companies that account for certain leases on an "off balance sheet" basis would be required to account for such leases "on balance sheet." This change would remove many of the differences in the way companies account for owned property and leased property, and could have a material effect on various aspects of our tenants' businesses, including their credit quality and the factors they consider in deciding whether to own or lease properties. If the proposal is adopted, it could cause companies that lease properties to prefer shorter lease terms, in an effort to reduce the leasing liability required to be recorded on their balance sheets. The proposal could also make lease renewal options less attractive, as, under certain circumstances, the rule would require a tenant to assume that a renewal right will be exercised and accrue a liability relating to the longer lease term.

Risks Related to Our Relationships with CWH and RMR and its Affiliates

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

We have no employees. Personnel and services that we require are provided to us under contracts with RMR. Our ability to achieve our business objectives depends on RMR and its ability to manage our properties, identify and complete new acquisitions for us and to implement our growth strategy. Accordingly, 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 fees we pay RMR under our management agreements, and as a result our expenses may increase.

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

As of February 21, 2013, CWH owned approximately 18.2% of our outstanding common shares. For so long as CWH continues to retain a significant ownership stake in us, CWH may be able to effectively 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 effectively 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 making of distributions on our common shares; and
•: the number of common shares available for issuance under our equity compensation plans.

CWH's significant ownership in us and possible resulting ability to effectively control us may discourage transactions involving a change of control, including transactions in which you as a holder of our common shares might otherwise receive a premium for your common shares over the then current market price.

Our management structure and agreements and relationships with CWH and RMR may restrict our investment activities and may create conflicts of interest or the perception of such conflicts.

RMR is authorized to follow broad operating and investment guidelines and, therefore, has discretion in determining the types of properties that will be appropriate investments for us, as well as our individual operating and investment decisions. Our Board of Trustees periodically reviews our operating and investment guidelines and our operating activities and investments 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 M. Portnoy and Adam D. Portnoy.

In our management agreements with RMR, we acknowledge that RMR manages other businesses, including four other NYSE-listed REITs, and is not required to present us with investment opportunities that RMR determines are within the investment focus of another business managed by RMR. RMR has discretion to determine which investment opportunities to present to us or to other businesses it manages. Accordingly, we may lose investment opportunities to, and may compete for tenants with other businesses managed by RMR. We have also agreed with RMR to first offer any property that we determine to sell and that is within the principal investment focus of another REIT managed by RMR to such REIT prior to entering into any sale or other disposition arrangement with respect to such property.

RMR also acts as the manager for four other NYSE-listed REITs: CWH, which primarily owns and operates commercial office and industrial buildings; HPT, which owns hotels and travel centers; SNH, which primarily owns healthcare, senior living properties and medical office buildings; and SIR, a majority owned subsidiary of CWH which is focused on owning and investing in net leased, single tenant properties. RMR also provides services to other publicly and privately owned companies, including FVE, which operates senior living communities; TA, which operates and franchises travel centers; and Sonesta, which operates, manages and franchises hotels, resorts and cruise ships. These

multiple responsibilities to public companies and other businesses could create competition for the time and efforts of RMR and Barry M. Portnoy and Adam D. Portnoy. Also, RMR's multiple responsibilities to us and CWH may create potential conflicts of interest, or the appearance of such conflicts of interest. In addition, we participate with RMR, CWH, HPT, SNH, SIR, FVE and TA in a combined insurance program through Affiliates Insurance Company, an Indiana insurance company, or AIC. Along with RMR, CWH, HPT, SNH, SIR, FVE and TA we have invested in AIC, and all of our Trustees are directors of AIC.

Barry M. Portnoy is Chairman and an employee of RMR, and Adam D. 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 other companies to which RMR provides management services. All of our executive officers are also executive officers of RMR. The foregoing individuals may hold equity in or positions with other companies to which RMR provides management services. 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 related parties.

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

We pay RMR fees based in part upon the historical cost of our investments (including acquisition costs) which at any time may be more or less than the fair market value of those investments, the gross rents we collect from tenants and the cost of construction we incur at our properties which is supervised by RMR, plus an incentive fee based upon certain increases in our FFO Per Share (as defined in our management agreements with RMR). See "Business—Manager." Our fee arrangements with RMR could encourage RMR to advocate acquisitions of properties, to undertake construction activities or to overpay for acquisitions or construction. These arrangements may also encourage RMR to discourage our sales of properties. Our management agreements were negotiated between related 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 unrelated 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 revolving credit facility and term loan agreements 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. We may be unable to duplicate, without considerable cost increases, the quality and depth of management available to us by contracting with RMR if we become a self managed company or if we contract with unrelated third parties. For these reasons, our management agreements with RMR may discourage a change of control of us, including a change of control which might result in payment of a premium for our common shares.

Provisions in our transaction agreement with CWH and our management agreements with RMR may restrict our investment activities and create conflicts of interest or the perception of 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. Under our management agreements with RMR, we have also agreed to first offer any property within the principal investment focus of another REIT to which RMR provides management services to such REIT prior to entering into any sale or other disposition arrangement with respect to such property. 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, but our management agreements afford RMR discretion to determine which leasing opportunities to present to us or to other businesses managed by RMR. There is no assurance that any conflicts created by these agreements will be resolved in our favor.

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

CWH is not generally prohibited from selling some or all of its common 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 common shares. However, CWH has a history of successfully divesting certain of its properties into new REITs and then selling or distributing to its shareholders its stake in such REITs over time. In addition, speculation by the press, stock analysts, our shareholders or others regarding CWH's intention to dispose of its common shares could adversely affect the market price of our common shares. So long as CWH continues to retain significant ownership in us, the market price of our common shares may be adversely impacted. Accordingly, your common shares may be worth less than they would be if CWH did not have significant ownership in 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 volatility in the overall market or declines in the market price of a company's securities, shareholder litigation, dissident shareholder trustee nominations and dissident shareholder proposals have often been instituted against companies alleging conflicts of interest in business dealings with affiliated and related persons and entities. Our relationships with RMR, CWH, AIC, the other businesses and entities to which RMR provides management services, Barry M. Portnoy and Adam D. Portnoy and with other related parties of RMR may precipitate such activities. These activities, if instituted against us, could result in substantial costs and a diversion of our management's attention.

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

We have invested approximately $5.2 million in 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. We, RMR, CWH and five other companies to which RMR provides management services each own 12.5% of AIC, and we and those other AIC shareholders participate in a combined insurance program designed and reinsured in part by AIC. 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 than may be otherwise available to us or by participating in any profits which we may realize as an owner of AIC. These beneficial financial results may not occur and we may need to invest additional capital in order to continue to pursue these results. AIC's business involves the risks typical of an insurance business, including the risk that it may not operate profitably. 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 law, may prevent our shareholders from receiving a takeover premium or from implementing changes.

Our declaration of trust prohibits any shareholder other than CWH, RMR and their affiliates from owning (directly and by attribution) more than 9.8% of the number or value of shares of any class or series of our outstanding shares of beneficial interest, including our common 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 law may further deter persons from attempting to acquire control of us and implement changes that may be beneficial to our shareholders, including, for example, provisions relating to:

•: the division of our Trustees into three classes, with the term of one class expiring each year, which could delay a change of control;
•: shareholder voting rights and standards for the election of trustees and other provisions which require larger majorities for approval of actions which are not approved by our Trustees than for actions which are approved by our Trustees;
•: 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", as defined in our governing documents;
•: limitations on the ability of our shareholders to propose nominees for election as trustees and propose other business to be considered at a meeting of our shareholders;
•: limitations on the ability of our shareholders to remove our Trustees;
•: the authority of our Board of Trustees, and not our shareholders, to adopt, amend or repeal our bylaws and to fill vacancies on our Board of Trustees;
•: the fact that only our 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 or for another proposal of business not approved by our Board of Trustees may be required to receive pre-clearance from the concerned insurance regulators; 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 number of authorized common 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 common shares or otherwise be in the best interests of our shareholders), to increase or decrease the number of shares of any class, 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 common shares or any new class 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 any of our shares they own or otherwise effect a change of our policies or a change in our control.

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 agreements 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. However, except with respect to proceedings to enforce rights to indemnification, we will indemnify any person referenced in the previous sentence in connection with a proceeding initiated by such person against us only if such proceeding is authorized by our Board of Trustees or shareholders. 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.

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

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

We may change our operational, financing and investment policies without shareholder approval, and we may become more highly leveraged, which may increase our risk of default under our debt obligations.

Our Board of Trustees determines our operational, financing 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. Policy changes could adversely affect the market value of our common shares and our ability to make distributions to our shareholders. Further, our organizational documents do not limit the amount or percentage of indebtedness, funded or otherwise, that we may incur. Our Board of Trustees may alter or eliminate our current policy on borrowing at any time without shareholder approval. If this policy changed, we could become more highly leveraged, which could result in an increase in our debt service costs. Higher leverage also increases the risk of default on our obligations. In addition, a change in our investment policies, including the manner in which we allocate our resources across our portfolio or the types of assets in which we seek to invest, may increase our exposure to interest rate risk, real estate market fluctuations and liquidity risk.

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 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. However, we cannot be certain that, upon review or audit, the IRS will agree with this conclusion. Furthermore, there is no guarantee that the federal government will not someday eliminate REITs under the IRC.

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 shareholders. In order to meet these requirements, it may be necessary for us to sell or forgo 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 revolving credit facility and term loan agreements, 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.

Dividends payable by U.S. corporations to noncorporate shareholders, such as individuals, trusts and estates, are generally eligible for reduced tax rates. 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 entities that pay dividends, thereby reducing the demand and market price of our shares.

REIT distribution requirements could adversely affect our ability to execute our business plan.

We generally must distribute annually at least 90% of our taxable income, subject to certain adjustments and excluding any net capital gain, in order for federal corporate income tax not to apply to earnings that we distribute. To the extent that we satisfy this distribution requirement, but distribute less than 100% of our taxable income, we will be subject to federal corporate income tax on our undistributed taxable income. We intend to make distributions to our shareholders to comply with the REIT requirements of the IRC. In addition, we will be subject to a 4% nondeductible excise tax if the actual amount that we pay out to our shareholders in a calendar year is less than a minimum amount specified under federal tax laws.

From time to time, we may generate taxable income greater than our income for financial reporting purposes prepared in accordance with U.S. generally accepted accounting principles, or GAAP, or differences in timing between the recognition of taxable income and the actual receipt of cash may occur. If we do not have other funds available in these situations we could be required to borrow funds on unfavorable terms, sell investments at disadvantageous prices or distribute amounts that would otherwise be invested in future acquisitions to make distributions sufficient to enable us to pay out enough of our taxable income to satisfy the REIT distribution requirement and to avoid corporate income tax and the 4% excise tax in a particular year. These alternatives could increase our costs or reduce our shareholders' equity. Thus, compliance with the REIT requirements may hinder our ability to grow, which could adversely affect the value of our shares.

Even if we qualify and remain qualified as a REIT, we may face other tax liabilities that reduce our cash flow.

Even if we qualify and remain qualified for taxation as a REIT, we may be subject to certain federal, state and local taxes on our income and assets, including taxes on any undistributed income, excise taxes, state or local income, property and transfer taxes, such as mortgage recording taxes, and other taxes. See "Business—Federal Income Tax Considerations—Taxation as a REIT." In addition, in order to meet the REIT qualification requirements, prevent the recognition of certain types of non-cash income, or avert the imposition of a 100% tax that applies to certain gains derived by a REIT from dealer property or inventory, we may hold some of our assets and operations through our TRS or other subsidiary corporations that will be subject to corporate level income tax at regular rates. Any of these taxes would decrease cash available for distribution to our shareholders.

Risks Related to Our Securities

We cannot assure that we will continue to make distributions to our shareholders and distributions we may make may include a return of capital.

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

•: our ability to make distributions will be adversely affected if any of the risks described herein occur;
•: our making of distributions is subject to compliance with restrictions contained in our revolving credit facility and term loan agreements; 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 results of operations, our financial condition, debt and equity capital available to us, our expectation of our future capital requirements, our funds from operations, or FFO, our Normalized FFO, restrictive covenants in our financial or other contractual arrangements (including those in our revolving credit facility and term loan agreements), tax law requirements to maintain our status as a REIT and restrictions under Maryland law.

For these reasons, among others, our distribution rate may decline or we may cease making distributions. Also, our distributions may include a return of capital.

Item 2. Properties

General. As of December 31, 2012, we owned 84 properties located in 32 states and the District of Columbia containing approximately 10.2 million rentable square feet. As of December 31, 2012, 62 of those properties, with approximately 7.6 million rentable square feet, were primarily leased to the U.S. Government, 18 of those properties, with approximately 2.1 million rentable square feet, were primarily leased to 10 state governments, one of those properties, with approximately 187,060 rentable square feet, was leased to the United Nations, an international intergovernmental organization, and three of those properties, with approximately 256,586 rentable square feet, were being offered for lease.

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

Our common shares are traded on the NYSE (symbol: GOV). The following table sets forth for the periods indicated the high and low sale prices for our common shares as reported by the NYSE composite transaction reports:

	High		Low

2012
First Quarter	$	24.87	$	22.03

Second Quarter		27.50		24.27
Third Quarter		27.80		20.50
Fourth Quarter		24.29		19.68

The closing price of our common shares on the NYSE on February 19, 2013, was $25.51 per common share.

As of February 19, 2013, there were 106 shareholders of record, and we estimate that as of such date there were in excess of 43,817 beneficial owners of our common shares.

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

	Dividends Paid Per Common Share

	2012		2011
First Quarter	$	0.42	$	0.41

Third Quarter		0.42		0.42
Fourth Quarter		0.43		0.42

Total	$	1.69	$	1.67

All common share distributions shown in the table above have been paid. We currently intend to continue to declare and pay common share distributions on a quarterly basis in cash. However, the timing, amount and form of distributions will be made at the discretion of our Board of Trustees and will depend upon various factors that our Board of Trustees deems relevant, including, but not limited to, our results of operations, our financial condition, debt and equity capital available to us, our expectation of our future capital requirements, our FFO, our Normalized FFO, restrictive covenants in our financial or other contractual arrangements (including those in our revolving credit facility and term loan agreements), tax law requirements to maintain our status as a REIT and restrictions under Maryland law. Therefore, we cannot assure 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 in Part IV, Item 15 of this Annual Report on Form 10-K.

OVERVIEW

As of December 31, 2012, we owned 84 properties located in 32 states and the District of Columbia containing approximately 10.2 million rentable square feet, of which 67.5% was leased to the U.S. Government, 17.0% was leased to 10 state governments and 1.8% was leased to the United Nations, an international intergovernmental organization. The U.S. Government, 10 state governments and the United Nations combined were responsible for 93.9% and 91.9% of our annualized rental income, as defined below, as of December 31, 2012 and 2011, respectively.

Property Operations

As of December 31, 2012, 92.5% of our rentable square feet were leased, compared to 95.0% of our rentable square feet as of December 31, 2011. Occupancy data for our properties as of December 31, 2012 and 2011 is as follows (square feet in thousands):

	All Properties December 31,						Comparable Properties⁽¹⁾ December 31,

	2012			2011			2012			2011
Total properties (end of period)		84			71			55			55
Total square feet		10,217			8,953			6,806			6,806
Percent leased⁽²⁾		92.5	%		95.0	%		91.1	%		95.1	%

⁽¹⁾: Based on properties we owned on December 31, 2012 and which we owned continuously since January 1, 2011. Our comparable properties increased from 33 properties at December 31, 2011 as a result of acquisitions we completed during the year ended December 31, 2010.
⁽²⁾: Percent leased includes (i) space being fitted out for tenant occupancy pursuant to our lease agreements, if any, and (ii) space which is leased, but is not occupied or is being offered for sublease by tenants, if any, as of the measurement date.

The average annual effective rental rate per square foot, as defined below, for our properties for the years ended December 31, 2012 and 2011 are as follows:

	Year ended December 31,

	2012		2011
Average annual effective rental rate per square foot:⁽¹⁾
All properties	$	24.48	$	24.46
Comparable properties⁽²⁾	$	24.06	$	23.92

⁽¹⁾: Average annual effective rental rate per square foot represents total rental income during the period specified divided by the average rentable square feet leased during the period specified.
⁽²⁾: Comparable properties for the year ended December 31, 2012 consist of 55 properties we owned on December 31, 2012 and which we owned continuously since January 1, 2011.

We currently believe that U.S. property leasing market conditions are slowly improving, but remain weak in many U.S. markets. Our historical experience, including that of our predecessor, CWH, with

respect to properties of the type we own that are majority leased to government tenants has been that government tenants frequently renew leases to avoid the costs and disruptions that may result from relocating their operations. We believe that current budgetary pressures may cause increased demand for leased space by government tenants, as opposed to new buildings built on behalf of government tenants. However, these same increased budgetary pressures upon the U.S. Government and state governments could also result in a decrease in government employment, an increase in space utilization rates by government tenants and consolidation of operations into government owned properties, thereby reducing the need for government leased space. Accordingly, we are unable to reasonably project what the financial impact of market conditions will be on our financial results for future periods.

As of December 31, 2012, leases totaling 430,505 rentable square feet are scheduled to expire through March 31, 2013. Based upon current market conditions and tenant negotiations for leases scheduled to expire through March 31, 2013, we expect that rental rates we are likely to achieve on new or renewed leases will, in the aggregate and on a weighted average basis, be higher than the rates currently being paid, thereby generally resulting in higher revenue from the same space absent an increase in vacancies. However, we cannot assure that the rental rates we expect will occur or that we will not experience material declines in our rental income due to vacancies upon lease expirations. Prevailing market conditions at the time our leases expire will generally determine lease renewals and rental rates for space in our properties; and market conditions are generally beyond our control.

⁽¹⁾: The year of lease expiration is pursuant to current contract terms. Some government tenants have the right to vacate their space before the stated expirations of their leases. As of December 31, 2012, government tenants occupying approximately 8.6% of our rentable square feet and responsible for approximately 7.1% of our annualized rental income as of December 31, 2012 have currently exercisable rights to terminate their leases before the stated expirations. Also in 2013, 2014, 2015, 2016, 2017, 2018, 2019 and 2020, early termination rights become exercisable by other tenants who currently occupy an additional approximately 3.5%, 3.9%, 0.6%, 6.4%, 2.4%, 1.1%, 3.6% and 0.6% of our rentable square feet, respectively, and contribute an additional approximately 3.0%, 4.4%, 0.5%, 9.5%, 3.4%, 1.4%, 4.2% and 0.7% of our annualized rental income, respectively, as of December 31, 2012. In January 2013, we were notified by one of our

tenants, representing approximately 1.0% of our rentable square feet and responsible for approximately 0.9% of our annualized rental income as of December 31, 2012, that it intends to exercise its right to vacate its space in July 2013 prior to the stated expiration of its lease in January 2015. In addition as of December 31, 2012, 12 of our state government tenants have currently exercisable rights to terminate their leases if these states do not appropriate rent in their respective annual budgets. These 12 tenants occupy approximately 7.6% of our rentable square feet and contribute approximately 7.6% of our annualized rental income as of December 31, 2012.

(2): Occupied square feet is pursuant to leases existing as of December 31, 2012, and includes (i) space being fitted out for tenant occupancy pursuant to our lease agreements, if any, and (ii) space which is leased, but is not occupied or is being offered for sublease by tenants, if any.
(3): Annualized rental income is defined as the annualized contractual base rents from our tenants pursuant to our lease agreements with them as of December 31, 2012, plus straight line rent adjustments and estimated recurring expense reimbursements to be paid to us, and excluding lease value amortization.

Acquisition and Disposition Activities (dollar amounts in thousands)

During the year ended December 31, 2012, we acquired 13 properties for an aggregate purchase price of $213,974, excluding acquisition related costs. We acquired these properties at a range of capitalization rates from 7.4% to 9.4%, with a weighted average (by purchase price) capitalization rate of 8.2%. We calculate the capitalization rate for property acquisitions as the ratio of (x) annual straight line rental income, excluding the impact of above and below market lease amortization, based on leases then in effect at the acquisition date, less estimated annual property operating expenses, excluding depreciation and amortization expense, to (y) the acquisition purchase price, including assumed debt and excluding acquisition costs.

In January and February 2013, we entered agreements to sell two properties for an aggregate sale price of $18,500, excluding closing costs. The net book value of these two properties, net of a $494 loss on asset impairment recorded in the three months ended December 31, 2012, totaled $10,084 at December 31, 2012. These pending sales are subject to the buyers' satisfactory completion of diligence and other customary closing conditions; accordingly, we cannot assure that we will sell these properties.

For more information about these transactions, please see Note 4 to the Notes to our Consolidated Financial Statements included in Part IV, Item 15 of this Annual Report on Form 10-K.

Our strategy related to property acquisitions and dispositions is described in "Business—Our Growth Strategy" of this Annual Report on Form 10-K. Although we currently have no properties under contract to acquire, we continue to explore and evaluate for possible acquisition additional properties that are majority leased to government tenants; however, we cannot assure that we will reach any agreement to acquire such properties.

Although we may offer for sale additional properties on occasion, we do not currently plan to dispose of any of our properties other than those described above. Future changes in market conditions, property performance or our plans with regard to particular properties may change our disposition strategy.

(1): Comparable properties consist of 55 properties we owned on December 31, 2012 and which we owned continuously since January 1, 2011.
(2): Acquired properties consist of the 29 and 16 (which 16 are included in the previously referenced 29) properties we owned on December 31, 2012 and December 31, 2011, respectively, and which we acquired during the period from January 1, 2011 to December 31, 2012.
(3): We calculate net operating income, or NOI, as shown above. We define NOI as income from our real estate less our property operating expenses. NOI excludes amortization of capitalized tenant improvement costs and leasing commissions. We consider NOI to be an appropriate supplemental measure to net income because it may help both investors and management to understand the operations of our properties. We use NOI internally to evaluate individual and company wide property level performance, and we believe that NOI provides useful information to investors regarding our results of operations because it reflects only those income and expense items that are incurred at the property level and may facilitate comparisons of our operating performance between periods. The calculation of NOI excludes certain components of net income in order to provide results that are more closely related to our properties' results of operations. NOI does not represent cash generated by operating activities in accordance with GAAP and should not be considered as an alternative to net income, operating income or cash flow from operating activities, determined in accordance with GAAP, or as an indicator of our financial performance or liquidity, nor is this measure necessarily indicative of sufficient cash flow to fund all of our needs. We believe that NOI may facilitate an understanding of our consolidated historical operating results. This measure should be considered in conjunction with net income, operating income and cash flow from operating activities as presented in our Consolidated Statements of Income and Comprehensive

Income and Consolidated Statements of Cash Flows. Other real estate investment trusts, or REITs, and real estate companies may calculate NOI differently than we do.

(4): We calculate funds from operations, or FFO, and Normalized FFO as shown above. FFO is calculated on the basis defined by The National Association of Real Estate Investment Trusts, or NAREIT, which is net income, calculated in accordance with GAAP, plus real estate depreciation and amortization and loss on asset impairment, as well as other adjustments currently not applicable to us. Our calculation of Normalized FFO differs from NAREIT's definition of FFO because we exclude acquisition related costs. We consider FFO and Normalized FFO to be appropriate measures of operating performance for a REIT, along with net income, operating income and cash flow from operating activities. We believe that FFO and Normalized FFO provide useful information to investors because by excluding the effects of certain historical amounts, such as depreciation expense, FFO and Normalized FFO may facilitate a comparison of our operating performance between periods. FFO and Normalized FFO are among the factors considered by our Board of Trustees when determining the amount of distributions to our shareholders. Other factors include, but are not limited to, requirements to maintain our status as a REIT, limitations in our revolving credit facility and term loan agreements, the availability of debt and equity capital to us, our expectation of our future capital requirements and operating performance, and our expected needs and availability of cash to pay our obligations. FFO and Normalized FFO do not represent cash generated by operating activities in accordance with GAAP and should not be considered as alternatives to net income, operating income or cash flow from operating activities, determined in accordance with GAAP, or as indicators of our financial performance or liquidity, nor are these measures necessarily indicative of sufficient cash flow to fund all of our needs. We believe that FFO and Normalized FFO may facilitate an understanding of our consolidated historical operating results. These measures should be considered in conjunction with net income, operating income and cash flow from operating activities as presented in our Consolidated Statements of Income and Comprehensive Income and Consolidated Statements of Cash Flows. Other REITs and real estate companies may calculate FFO and Normalized FFO differently than we do.

We refer to the 55 properties we owned on December 31, 2012 and which we have owned continuously since January 1, 2011 as comparable properties. We refer to the 29 and 16 (which 16 are included in the previously referenced 29) properties that we owned as of December 31, 2012 and 2011, respectively, which we purchased during the period from January 1, 2011 to December 31, 2012, as acquired properties. Our consolidated income statement for the year ended December 31, 2012 includes the operating results of 16 acquired properties for the entire year and 13 acquired properties for less than the entire year, as we purchased those 16 properties prior to January 1, 2012 and we purchased those 13 properties during that period. Our consolidated income statement for the year ended December 31, 2011 includes the operating results of 16 acquired properties for less than the entire year, as those properties were purchased during 2011.

References to changes in the income and expense categories below relate to the comparison of consolidated results for the year ended December 31, 2012, compared to the year ended December 31, 2011.

Rental income. The increase in rental income reflects the effects of acquired properties, partially offset by lower revenues for comparable properties. Rental income for acquired properties increased $9,202 from properties acquired during 2012 and $30,228 from properties acquired during 2011. Rental income for comparable properties decreased primarily due to a decrease in occupancy at three of our properties, partially offset by the effect of net rental increases at certain of our other properties. Rental income includes non-cash straight line rent adjustments totaling $3,553 in 2012 and $1,729 in 2011 and amortization of acquired leases and assumed lease obligations totaling ($1,812) in 2012 and ($498) in 2011.

Real estate taxes. The increase in real estate taxes primarily reflects the effects of acquired properties. Real estate taxes for acquired properties increased $806 from properties acquired during 2012 and $3,083 from properties acquired during 2011. Real estate taxes for comparable properties increased slightly due to the combined effects of higher tax assessments at certain of our properties, partially offset by lower assessed values from successful property tax appeals at certain of our other properties.

Utility expenses. The increase in utility expenses reflects the effects of acquired properties, partially offset by lower utility expenses for comparable properties. Utility expenses for acquired properties increased $521 from properties acquired during 2012 and $2,906 from properties acquired during 2011. Utility expenses at comparable properties declined due to decreased tenant usage as a result of the warmer than normal temperatures experienced in many parts of the United States in early

2012, a decrease in usage at certain of our properties as a result of increased vacancies and the impact of energy conservation efforts at certain of our properties.

Other operating expenses. Other operating expenses consist of property management fees, salaries and benefit costs of property level personnel, repairs and maintenance expense, cleaning expense and other direct costs of operating our properties. The increase in other operating expenses reflects the effects of acquired properties, partially offset by lower expenses for comparable properties. Other operating expenses for acquired properties increased $1,457 for properties acquired during 2012 and $6,206 for properties acquired during 2011. Other operating expenses at comparable properties decreased primarily as a result of lower snow removal costs at certain of our properties, partially offset by higher repair and maintenance expense at certain of our properties.

Depreciation and amortization. The increase in depreciation and amortization reflects the effect of property acquisitions and improvements made to certain of our properties since January 1, 2011. Depreciation and amortization for acquired properties increased $2,910 for properties acquired during 2012 and $9,154 for properties acquired during 2011.

Loss on asset impairment. Loss on asset impairment in 2012 reflects the write down to estimated fair value for one property we entered an agreement to sell in February 2013.

Acquisition related costs. Acquisition related costs represent legal and due diligence costs incurred in connection with our acquisition activity during 2012 and 2011.

General and administrative. General and administrative expenses consist of fees pursuant to our business management agreement with RMR, equity compensation expense, legal and accounting fees, Trustees' fees and expenses, securities listing and transfer agency fees and other costs relating to our status as a publicly traded company. The increase in general and administrative expenses primarily reflects and results from our property acquisitions since January 1, 2011.

Interest and other income. The decrease in interest and other income is primarily the result of a smaller average amount of investable cash in 2012 compared to 2011.

Interest expense. The increase in interest expense reflects a larger average outstanding debt balance during 2012 compared to 2011, partially offset by a lower weighted average interest rate in 2012.

Equity in earnings of an investee. Equity in earnings of an investee represents our proportionate share of earnings from our investment in AIC.

Income tax expense. The decrease in income tax expense is a result of lower state income taxes in 2012 compared to 2011.

Net income. Our net income increased in 2012 as compared to 2011 as a result of the changes noted above. On a per share basis, net income in 2012 is lower as compared to 2011 principally due to our issuance of common shares pursuant to a public offerings in 2012 and 2011.

(1): Comparable properties consist of 33 properties we owned on December 31, 2011 and which we owned continuously since January 1, 2010.
(2): Acquired properties consist of the 38 and 22 (which 22 are included in the previously referenced 38) properties we owned on December 31, 2011 and December 31, 2010, respectively, and which we acquired during the period from January 1, 2010 to December 31, 2011.

We refer to the 33 properties we owned on December 31, 2011 and which we have owned continuously since January 1, 2010 as comparable properties. We refer to the 38 and 22 (which 22 are included in the previously referenced 38) properties that we owned as of December 31, 2011 and 2010, respectively, which we purchased during the period from January 1, 2010 to December 31, 2011, as acquired properties. Our consolidated income statement for the year ended December 31, 2011 includes the operating results of 22 acquired properties for the entire year and 16 acquired properties for less than the entire year, as we purchased those 22 properties prior to January 1, 2011 and we purchased those 16 properties during that period. Our consolidated income statement for the year ended December 31, 2010 includes the operating results of 22 acquired properties for less than the entire year, as those properties were purchased during 2010.

References to changes in the income and expense categories below relate to the comparison of consolidated results for the year ended December 31, 2011, compared to the year ended December 31, 2010.

Rental income. The increase in rental income reflects the effects of acquired properties, partially offset by lower revenues for comparable properties. Rental income for acquired properties increased $22,951 from properties acquired during 2011 and $39,976 from properties acquired during 2010. Rental income for the comparable properties decreased primarily due to a decrease in occupancy at one of our properties and lower real estate tax expense recoveries at certain of our properties, partially offset by the effect of net rental increases at certain of our other properties. Rental income includes non-cash straight line rent adjustments totaling $1,729 in 2011 and ($5) in 2010 and amortization of acquired leases and assumed lease obligations totaling ($498) in 2011 and ($34) in 2010.

Real estate taxes. The increase in real estate taxes primarily reflects the effects of acquired properties. Real estate taxes for acquired properties increased $2,155 from properties acquired during 2011 and $5,292 from properties acquired during 2010. Real estate taxes for comparable properties decreased primarily due to the effects of lower assessed values from successful property tax appeals at certain of our properties.

Utility expenses. The increase in utility expenses reflects the effects of acquired properties. Utility expenses for acquired properties increased $1,771 from properties acquired during 2011 and $4,523 from properties acquired during 2010. Utility expenses for comparable properties were essentially unchanged between 2011 and 2010.

Other operating expenses. The increase in other operating expenses reflects the effects of acquired properties in addition to a slight increase in other operating expenses for comparable properties. Other operating expenses for acquired properties increased $3,517 for properties acquired during 2011 and $8,044 for properties acquired during 2010. Other operating expenses for comparable properties increased primarily due to increased repair and maintenance costs at certain of our properties.

Depreciation and amortization. The increase in depreciation and amortization reflects the effect of property acquisitions and improvements made to certain of our properties since January 1, 2010. Depreciation and amortization for acquired properties increased $6,773 for properties acquired during 2011 and $8,834 for properties acquired during 2010.

Acquisition related costs. Acquisition related costs represent legal and due diligence costs incurred in connection with our acquisition activity during 2011 and 2010.

General and administrative. The increase in general and administrative expenses primarily reflects the effect of our property acquisitions since January 1, 2010.

Interest and other income. Interest and other income is essentially unchanged between 2011 and 2010.

Interest expense. The increase in interest expense reflects a larger average outstanding balance under our revolving credit facility in 2011 compared to 2010 and interest expense related to the mortgage notes we assumed in connection with certain of our 2010 and 2011 acquisitions, partially offset by a lower weighted average interest rate for borrowings under our revolving credit facility in 2011.

Loss on extinguishment of debt. The loss on extinguishment of debt is the result of our write off of unamortized financing costs associated with the early termination of our $250,000 secured revolving credit facility in 2010.

Equity in earnings (losses) of an investee. Equity in earnings (losses) of an investee represents our proportionate share of earnings (losses) from our investment in AIC.

Income tax expense. The increase in income tax expense is a result of our higher operating income in 2011 compared to 2010 which is subject to state income taxes in certain jurisdictions.

Net income. Our net income increased in 2011 as compared to 2010 as a result of the changes noted above. On a per share basis, the percentage increase in net income in 2011 as compared to 2010 is lower due to our issuance of common shares pursuant to public offerings in 2010 and 2011.

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 common 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 common shares for the next 12 months and the foreseeable future thereafter. Our future cash flows from operating activities will depend primarily upon our ability to:

•: maintain or increase the occupancy of, and the rental rates at, our properties;
•: control operating cost increases at our properties; and
•: purchase additional properties which produce cash flows from operations in excess of our cost of acquisition capital.

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 and upon our ability to successfully acquire such properties.

Our changes in cash flows for the year ended December 31, 2012 compared to the year ended December 31, 2011 were as follows: (i) cash provided by operating activities increased from $80,487 in 2011 to $100,308 in 2012; (ii) cash used in investment activities decreased from ($390,551) in 2011 to ($232,467) in 2012; and (iii) cash provided by financing activities decreased from $310,899 in 2011 to $134,142 in 2012.

The increase in cash provided by operating activities for the year ended December 31, 2012 as compared to the year ended December 31, 2011 was due primarily to increased operating cash flow from our acquisitions of properties after January 1, 2011 and changes in our working capital. The decrease in cash used in investing activities for the year ended December 31, 2012 as compared to the year ended December 31, 2011 was due primarily to our acquisition of 16 properties for an aggregate purchase price of $387,491, excluding acquisition costs, during 2011, as compared to 13 properties for an aggregate purchase price of $213,626, excluding acquisition costs, during 2012. The decrease in cash provided by financing activities for the year ended December 31, 2012 as compared to the year ended December 31, 2011 was due primarily to a decrease in borrowings under our revolving credit facility required to fund our acquisition activities during 2012 as compared to 2011.

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

In order to fund acquisitions and to meet 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 a $550,000 unsecured revolving credit facility with a group of institutional lenders. The maturity date of our revolving credit facility is October 19, 2015 and, subject to the

payment of an extension fee and meeting certain other conditions, includes an option for us to extend the stated maturity date of our revolving credit facility by one year to October 19, 2016. In addition, our revolving credit facility includes a feature under which maximum borrowings may be increased to up to $1,100,000 in certain circumstances. Borrowings under our revolving credit facility bear interest at a rate of LIBOR plus a spread, which was 150 basis points as of December 31, 2012. We also pay a facility fee of 35 basis points per annum on the total amount of lending commitments under our revolving credit facility. Both the interest rate spread and the facility fee are subject to adjustment based upon changes to our credit ratings. We can borrow, repay and reborrow funds available under our revolving credit facility until maturity, and no principal repayment is due until maturity. As of December 31, 2012, the interest rate payable on borrowings under our revolving credit facility was 1.71%, and the weighted average interest rate for borrowings under our revolving credit facility was 1.75% for the year ended December 31, 2012. As of December 31, 2012 and February 19, 2013, we had $49,500 and $55,000, respectively, outstanding under our revolving credit facility and $500,500 and $495,000 available to borrow under our revolving credit facility.

On January 12, 2012, we entered into a five year $350,000 unsecured term loan. Our term loan matures on January 11, 2017, and is prepayable without penalty at any time. The amount outstanding under our term loan bears interest at a rate of LIBOR plus a spread that is subject to adjustment based upon changes to our credit ratings. As of December 31, 2012, the interest rate payable on the amount outstanding under our term loan was 1.96%. We used the net proceeds of our term loan to repay amounts outstanding under our revolving credit facility and to fund general business activities.

Our revolving credit facility agreement and our term loan agreement provide for acceleration of payment of all amounts due thereunder upon the occurrence and continuation of certain events of default, including a change of control of us and the termination of our business management agreement with RMR. Our revolving credit facility agreement and our term loan agreement also contain a number of covenants, including covenants that restrict our ability to incur debts or to make distributions under certain circumstances and require us to maintain financial ratios and a minimum net worth. We believe we were in compliance with the terms and conditions of our revolving credit facility agreement and our term loan agreement at December 31, 2012.

On October 19, 2012, we issued 7,500,000 common shares in a public offering at a price of $23.25 per share, raising net proceeds of approximately $166,718. We used the net proceeds of this offering to repay amounts outstanding under our revolving credit facility.

We currently expect to use cash balances, borrowings under our revolving credit facility and net proceeds from offerings of equity or debt securities to fund our future operations, capital expenditures, distributions to our shareholders and any future property acquisitions. When significant amounts are outstanding under our revolving credit facility or the maturity date of our revolving credit facility or our other debts approach, we intend to explore alternatives for repaying or refinancing such amounts. Such alternatives may include incurring additional term debt, issuing new equity securities, extending the maturity date of our revolving credit facility and entering into a new revolving credit facility. Although we cannot assure 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 currently 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 we cannot assure that we will be able to successfully carry out this intention.

On each of February 24, 2012, May 24, 2012 and August 22, 2012, we paid a $0.42 per share distribution to our common shareholders. On November 21, 2012, we paid a $0.43 per share distribution to our common shareholders. We funded these distributions using cash on hand and borrowings under our revolving credit facility. On January 10, 2013, we declared a distribution payable to common shareholders of record on January 25, 2013, in the amount of $0.43 per share. We expect to pay this distribution on or about February 22, 2013 using existing cash balances and borrowings under our revolving credit facility.

During the years ended December 31, 2012 and 2011, cash expenditures made and capitalized at our properties for tenant improvements, leasing costs, building improvements and development and redevelopment activities were as follows (dollars in thousands):

	Year Ended December 31,

	2012		2011
Leasing capital⁽¹⁾	$	11,109	$	3,853
Building improvements⁽²⁾	$	4,160	$	2,473
Development, redevelopment and other activities⁽³⁾	$	6,474	$	2,945

⁽¹⁾: Leasing capital includes tenant improvements and other tenant inducements and leasing costs such as brokerage commissions.
⁽²⁾: Building improvements generally include expenditures to replace obsolete building components and expenditures that extend the useful life of existing assets.
⁽³⁾: Development, redevelopment and other activities generally include non-recurring expenditures that we believe increase the value of our properties.

Leases totaling 1,514,125 rentable square feet expired during the year ended December 31, 2012. During the year ended December 31, 2012, we entered into leases totaling 1,192,532 rentable square feet, which includes lease renewals of 1,094,509 rentable square feet. The weighted average (by rentable square feet) rental rates for leases of 1,055,123 rentable square feet entered into with government tenants during the year ended December 31, 2012 increased by 10.7%, when compared to the weighted average (by rentable square feet) rental rates previously charged for the same space. The weighted average (by rentable square feet) rental rates for leases of 137,409 rentable square feet entered into with non-government tenants during the year ended December 31, 2012 decreased by 1.5% when compared to the weighted average (by rentable square feet) rental rates previously charged for the same space.

During the year ended December 31, 2012 commitments made for expenditures, such as tenant improvements and leasing costs, in connection with leasing space, were as follows (dollars in thousands, except per square foot amounts):

	New Leases		Lease Renewals		Total

Rentable square feet leased during the period		98,023		1,094,509		1,192,532
Tenant leasing costs and concession commitments⁽¹⁾	$	6,118	$	7,578	$	13,696
Tenant leasing costs and concession commitments per rentable square foot	$	62.41	$	6.92	$	11.48
Weighted average lease term (years)⁽²⁾		9.1		5.3		5.7
Total leasing costs and concession commitments per rentable square foot per year	$	6.88	$	1.30	$	2.02

⁽¹⁾: Includes commitments made for leasing expenditures and concessions, such as improvements, leasing commissions, tenant reimbursements and free rent.
⁽²⁾: Weighted based on the average annual contractual rents from our tenants pursuant to leases as of December 31, 2012, including straight line rent adjustments and estimated recurring expense reimbursements, but excluding lease value amortization.

As of December 31, 2012, our contractual obligations were as follows (dollars in thousands):

	Payments Due by Period

Contractual Obligations	Total		Less than 1 Year		1 - 3 Years		3 - 5 Years		More than 5 Years
Long term debt obligations	$	490,477	$	1,933	$	100,263	$	376,016	$	12,265
Tenant related obligations⁽¹⁾		9,538		8,866		614		19		39
Projected interest expense⁽²⁾		56,169		15,392		29,345		10,154		1,278

Total	$	556,184	$	26,191	$	130,222	$	386,189	$	13,582

⁽¹⁾: Committed tenant related obligations include leasing commissions and tenant improvements and are based on leases executed through December 31, 2012.
⁽²⁾: Projected interest expense is attributable to only our long term debt obligations as of December 31, 2012 at existing rates and is not intended to project future interest costs which may result from debt prepayments, new debt issuances or changes in interest rates.

Off Balance Sheet Arrangements

As of December 31, 2012, we had no off balance sheet arrangements that have had or that we expect would be reasonably likely to have a future material effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Debt Covenants (dollars in thousands)

Our principal debt obligations at December 31, 2012 were our $550,000 revolving credit facility, our $350,000 term loan and four secured mortgage loans assumed in connection with certain of our acquisitions. Our mortgage loans are non-recourse and do not contain any material financial covenants. Our revolving credit facility agreement and our term loan agreement contain 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 revolving credit facility agreement and our term loan agreement provide for acceleration of payment of all amounts outstanding upon the occurrence and continuation of certain events of default or upon a change of control of us, including a change in our management by RMR. We believe we were in compliance with all of our covenants under our revolving credit facility agreement and our term loan agreement at December 31, 2012.

Our revolving credit facility agreement and our term loan agreement contain cross default provisions, which are generally triggered upon default of any of our other debts of at least $25,000 or more that are recourse debts and to any other debts of $50,000 or more that are non-recourse debts. Termination of our business management agreement or property management agreement with RMR would cause a default under our revolving credit facility agreement and our term loan agreement, if not approved by the majority of our lenders.

Related Person Transactions (dollars in thousands)

We have relationships and historical and continuing transactions with our Trustees, our executive officers, RMR, CWH, AIC and other companies to which RMR provides management services and others affiliated with them. For example, we have no employees and personnel and various services we require to operate our business are provided to us by RMR pursuant to management agreements; and RMR is owned by our Managing Trustees. Also, as a further example, we have or had relationships with other companies to which RMR provides management services and which have trustees, directors and officers who are also trustees, directors or officers of ours or RMR, including: CWH, which is our former parent and is our largest shareholder and from which we have previously purchased properties that are majority leased to government tenants; and we, RMR, CWH and five other companies to which RMR provides management services each currently own 12.5% of AIC, an Indiana insurance company, and we and the other shareholders of AIC have property insurance in place providing $500,000 of coverage pursuant to an insurance program arranged by AIC and with respect to which AIC is a reinsurer of certain coverage amounts. For further information about these and other such relationships and related person transactions, please see Note 5 to the Notes to our Consolidated Financial Statements included in Part IV, Item 15 of this Annual Report on Form 10-K, which is incorporated herein by reference, and the section captioned "Business" above in Part I, Item 1 of this Annual Report on Form 10-K. In addition, for more information about these transactions and relationships and about the risks that may arise as a result of these and other related person transactions and relationships, please see elsewhere in this Annual Report on Form 10-K, including "Warning Concerning Forward Looking Statements" and Part I, Item 1A, "Risk Factors." Copies of certain of our agreements with these related parties, including our business management agreement and property management agreement with RMR, various agreements we have entered with CWH and our shareholders agreement with AIC and its shareholders, are publicly available as exhibits to our public filings with the SEC and accessible at 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 and AIC and their affiliated and related persons and entities benefit us and, in fact, provide us with competitive 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 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 acquired 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 acquired in place leases exclusive of the value of above market and below market acquired 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 in the past several years in the United States has been modest. Future inflation might have either positive or negative impacts on our business. 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 may result in decreased earnings unless it is offset by increased revenues. Our U.S. Government leases generally provide for annual rent increases based on a cost of living indexed adjustment to certain historical costs which may mitigate the adverse impact of those increased costs, although such rent increases may not completely offset the cost increases which we experience 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. The decision to enter into these agreements will be based on various factors, including the amount of our floating rate debt outstanding, our belief that material interest rate increases are likely to occur, the costs of and our expected benefit from these agreements and upon requirements of our borrowing arrangements. At present we have no such hedge arrangements.

Impact of Climate Change

The current political debate about climate change has resulted in various treaties, laws and regulations which are intended to limit carbon emissions. We believe these laws being enacted or proposed may cause energy costs at our properties to increase in the future. In an effort to reduce the effects of any increased energy costs in the future, we and our manager, RMR, continuously study ways to improve the energy efficiency at all of our properties. RMR is a member of the Energy Star Partner program, a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy which is focused on promoting energy efficiency at commercial properties through its "Energy Star" label program, and a member of the U.S. Green Building Council, a nonprofit organization focused on promoting energy efficiency at commercial properties through its leadership in energy and environmental design, or LEED®, green building certificate program. We do not expect the direct impact of these possible increases in energy costs resulting from laws designed to address climate change to be material to our results of operations because most of the increased costs either may be the responsibility of our tenants directly or in large part may be passed through by us to our tenants as additional lease payments; however, for certain of our leases, we may be unable to pass through such increased amounts. 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.

There have recently been severe weather activities in different parts of the country that some observers believe evidence global climate change, including the recent Hurricane Sandy that impacted portions of the eastern United States in October 2012. Such severe weather that may result from climate change may have an adverse effect on individual properties we own. We mitigate these risks by owning a diversified portfolio of properties and by procuring insurance coverage we believe adequate to protect us from material damages and losses from such activities. However, there can be no assurance that our mitigation efforts will be sufficient or that storms that may occur due to future climate change or otherwise could not have a material adverse effect on our business.

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 currently 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, 2012, our outstanding fixed rate debt consisted of the following:

Debt	Principal Balance				Annual Interest Expense			Interest Payments Due

Mortgage	$	48,653	5.73	%	$	2,827	2015	Monthly
Mortgage		24,441	6.21	%		1,539	2016	Monthly
Mortgage		9,369	7.00	%		656	2019	Monthly
Mortgage		8,514	8.15	%		694	2021	Monthly

	$	90,977			$	5,715

⁽¹⁾: The principal balances and interest rates are the amounts determined pursuant to the contracts. In accordance with GAAP, our carrying values and recorded interest expense may differ from these amounts because of market conditions at the time we assumed these debts. For more information, see Note 7 to the Notes to our Consolidated Financial Statements included in Item 15 of this Annual Report on Form 10-K.

Our mortgages require principal and interest payments through maturity pursuant to amortization schedules. Because these debts bear interest at a fixed rate, changes in market interest rates during the term of these debts will not affect our interest obligations. If these debts were refinanced at interest rates which are 100 bps higher or lower than shown above, our per annum interest cost would increase or decrease, respectively, by approximately $920.

Changes in market interest rates would 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, 2012, and discounted cash flow analysis through the respective maturity dates, and assuming no other changes in factors that may affect the fair value of our fixed rate debt obligations, a hypothetical immediate 100 bps increase in interest rates would decrease the fair value of those obligations by approximately $2,566, and a hypothetical immediate 100 bps decrease in interest rates would increase the fair value of those obligations by approximately $3,005.

Each of our fixed rate secured debt arrangements allows us to make repayments earlier than the stated maturity date. In some cases, we are not allowed to make early repayment prior to a cutoff date and we are generally allowed to make prepayments only at a premium equal to a make whole amount, as defined, which is generally designed to preserve a stated yield to the note holder. These prepayment rights may afford us opportunities to mitigate the risk of refinancing our debts at maturity at higher rates by refinancing prior to maturity.

At December 31, 2012, our floating rate debt consisted of $49,500 outstanding under our $550,000 unsecured revolving credit facility and our $350,000 unsecured term loan. Our revolving credit facility matures in October 2015, and subject to our meeting certain conditions, including our payment of an extension fee, we have the option to extend the stated maturity by one year to October 2016. No principal repayments are required under our revolving credit facility or term loan prior to maturity, and prepayments may be made, and redrawn subject to conditions, at any time without penalty. Borrowings under our revolving credit facility and term loan are in U.S. dollars and bear interest at a rate of LIBOR plus a spread that is subject to adjustment based upon changes to our credit ratings.

Accordingly, we are vulnerable to changes in U.S. dollar based short term rates, specifically LIBOR. There have been recent governmental inquiries regarding the setting of LIBOR, which may result in changes to the process that could have the effect of increasing LIBOR. In addition, upon renewal or refinancing of our revolving credit facility or our term loan, we are vulnerable to increases in interest rate spreads due to market conditions or our perceived credit risk. Generally, a change in interest rates generally would not affect the value of our floating rate debt but would affect our operating results.

The following table presents the impact a 100 bps increase in interest rates would have on our floating rate interest expense as of December 31, 2012:

	Impact of Changes in Interest Rates

	Interest Rate⁽¹⁾			Outstanding Debt		Total Interest Expense Per Year
At December 31, 2012		1.930	%	$	399,500	$	7,817
100 bps increase		2.930	%		399,500		11,868

⁽¹⁾: Weighted based on the outstanding borrowings as of December 31, 2012.

The foregoing table shows the impact of an immediate change in floating interest rates. If interest rates were to change gradually over time, the impact would be spread over time. Our exposure to fluctuations in floating interest rates will increase or decrease in the future with increases or decreases in the outstanding amount under our revolving credit facility or other floating rate debt.

The following table presents the impact a 100 bps increase in interest rates would have on our annual floating rate interest expense as of December 31, 2012 if we were fully drawn on our revolving credit facility and our term loan remained outstanding:

	Impact of Changes in Interest Rates

	Interest Rate⁽¹⁾			Outstanding Debt		Total Interest Expense Per Year
At December 31, 2012		1.930	%	$	900,000	$	17,611
100 bps increase		2.930	%		900,000		26,736

⁽¹⁾: Weighted based on the outstanding borrowings as of December 31, 2012.

Although we have no present plans to do so, we may in the future enter into hedge arrangements from time to time to mitigate our exposure to changes in interest rates.

The information required by this item is included in Item 15 of this Annual Report on Form 10-K.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

As of the end of the pweriod covered by this report, our management carried out an evaluation, under the supervision and with the participation of our Managing Trustees, our President and our Treasurer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures pursuant to Exchange Act Rules 13a-15 and 15d-15. Based upon that evaluation, our Managing Trustees, our President and our Treasurer and Chief Financial Officer concluded that our disclosure controls and procedures are effective.

There have been no changes in our internal control over financial reporting during the quarter ended December 31, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management Report on Assessment of Internal Control Over Financial Reporting

We are responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control system is designed to provide reasonable assurance to our management and Board of Trustees regarding the preparation and fair presentation of published financial statements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2012. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework. Based on our assessment, we believe that, as of December 31, 2012, our internal control over financial reporting is effective.

Ernst & Young LLP, the independent registered public accounting firm that audited our 2012 consolidated financial statements included in this Annual Report on Form 10-K, has issued an attestation report on our internal control over financial reporting. Its report appears elsewhere herein.

Item 9B. Other Information

Report of Independent Registered Public Accounting Firm

To the Trustees and Shareholders of Government Properties Income Trust

We have audited the accompanying consolidated balance sheets of Government Properties Income Trust (the "Company") as of December 31, 2012 and 2011, and the related consolidated statements of income and comprehensive income, shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2012. Our audits also included the financial statement schedule listed in the Index at Item 15(a). These financial statements and schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Government Properties Income Trust at December 31, 2012 and 2011, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2012, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Government Properties Income Trust's internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 21, 2013 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

To the Trustees and Shareholders of Government Properties Income Trust

We have audited Government Properties Income Trust's internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Government Properties Income Trust's management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in Management Report on Assessment of Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company's internal control over financial reporting based on our audit.

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

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

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

In our opinion, Government Properties Income Trust maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 2012 consolidated financial statements of Government Properties Income Trust and our report dated February 21, 2013 expressed an unqualified opinion thereon.

GOVERNMENT PROPERTIES INCOME TRUST

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(dollars in thousands, except per share data)

Note 1. Organization

Government Properties Income Trust, or the Company, we or us, was organized as a real estate investment trust, or REIT, under Maryland law on February 17, 2009 as a wholly owned subsidiary of CommonWealth REIT, or CWH. At the time of our organization, we issued 9.95 million of our common shares of beneficial interest, par value $.01 per share, or our common shares, to CWH. On April 24, 2009, we acquired 100% ownership of our 29 initial properties, or the Initial Properties, by means of a contribution from CWH to one of our subsidiaries. On June 8, 2009, we closed on our initial public offering, or IPO, and we became a separate publicly owned company.

As of December 31, 2012, we owned 84 properties, or the Properties, located in 32 states and the District of Columbia containing approximately 10.2 million rentable square feet.

Note 2. Summary of Significant Accounting Policies

Basis of Presentation. Prior to our IPO, CWH directly or indirectly wholly owned us, and we have presented applicable transactions at CWH's historical basis.

These consolidated financial statements include the accounts of us and our subsidiaries, all of which are 100% owned directly or indirectly by us. All intercompany transactions and balances have been eliminated.

We account for our investment in Affiliates Insurance Company, or AIC, using the equity method of accounting. Significant influence is present through common representation on the boards of trustees or directors of us and AIC. Our Managing Trustees are also owners of Reit Management & Research LLC, or RMR, which is the manager of us and AIC, and each of our Trustees is a director of AIC. See Note 5 for a further discussion of our investment in AIC.

Real Estate Properties. As required by U.S. generally accepted accounting principles, or GAAP, we have generally adopted the accounting treatment and policies for our properties and business which were previously employed by CWH. We record our Initial Properties at cost to CWH and our other properties at our cost and provide depreciation on real estate investments on a straight line basis over estimated useful lives ranging up to 40 years. We and CWH estimated the purchase price allocations and the useful lives of our properties. In some circumstances, we and CWH engaged independent real estate appraisal firms to provide market information and evaluations which are relevant to our purchase price allocations and determinations of useful lives; however, we are ultimately responsible for the purchase price allocations and determinations of useful lives.

We and CWH allocated the purchase prices of our properties to land, building and improvements based on determinations of the relative fair values of these assets assuming the properties are vacant. We and CWH determined the fair value of each property using methods similar to those used by independent appraisers. We and CWH allocated a portion of the purchase price of our properties to above market and below market leases based on the present value (using an interest rate which reflects the risks associated with acquired in place leases at the time each property was acquired by us or CWH) of the difference between (i) the contractual amounts to be paid pursuant to the acquired in place leases and (ii) our estimates of fair market lease rates for the corresponding leases, measured over a period equal to the terms of the respective leases. We and CWH allocated a portion of the purchase price to acquired in place leases and tenant relationships in an amount equal to the excess of (i) the purchase price paid for each property, after adjusting existing acquired in place leases to market

F-7

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(dollars in thousands, except per share data)

Note 2. Summary of Significant Accounting Policies (Continued)

rental rates, over (ii) the estimated fair value of the property, as if vacant. We and CWH allocated this aggregate value between acquired in place lease values and tenant relationships based on our evaluation of the specific characteristics of each tenant's lease. However, we have not separated the value of tenant relationships from the value of acquired in place leases because such value and related amortization expense is immaterial to the accompanying financial statements. In making these allocations, we considered factors such as estimated carrying costs during the expected lease up periods, including real estate taxes, insurance and other operating income and expenses and costs, such as leasing commissions, legal and other related expenses, to execute similar leases in current market conditions at the time a property was acquired by us or CWH. If the value of tenant relationships becomes material in the future, we may separately allocate those amounts and amortize the allocated amount over the estimated life of the relationships.

We amortize capitalized above market lease values (included in acquired in place real estate leases in our consolidated balance sheets) and below market lease values (presented as assumed real estate lease obligations in our consolidated balance sheets) as a reduction or increase, respectively, to rental income over the terms of the associated leases. Such amortization resulted in net decreases to rental income of $1,812, $498 and $34 during the years ended December 31, 2012, 2011 and 2010, respectively. We amortize the value of acquired in place leases (included in acquired in place real estate leases in our consolidated balance sheets), exclusive of the value of above market and below market acquired in place leases, over the terms of the associated leases. Such amortization amounted to $17,695, $12,573 and $4,593 during the years ended December 31, 2012, 2011 and 2010, respectively. When a lease is terminated prior to its stated expiration, we write off the unamortized amounts relating to that lease.

Capitalized above market lease values were $39,598 and $38,415 as of December 31, 2012 and 2011, respectively, net of accumulated amortization of $10,895 and $7,083, respectively. Capitalized below market lease values were $28,408 and $20,818 as of December 31, 2012 and 2011, respectively, net of accumulated amortization of $9,279 and $9,556, respectively. The value of acquired in place leases, exclusive of the value of above and below market acquired in place leases, were $148,500 and $105,123 as of December 31, 2012 and 2011, respectively, net of accumulated amortization of $32,719 and $18,861, respectively. Future amortization of net intangible lease assets and liabilities to be recognized over the current terms of the associated leases as of December 31, 2012 are estimated to be $20,538 in 2013, $19,943 in 2014, $17,780 in 2015, $15,988 in 2016, $14,410 in 2017 and $36,696 thereafter.

We regularly evaluate whether events or changes in circumstances have occurred that could indicate an impairment in the value of long lived assets. If there is an indication that the carrying value of an asset is not recoverable, we estimate the projected undiscounted cash flows to determine if an impairment loss should be recognized. We determine the amount of any impairment loss by comparing the historical carrying value to estimated fair value. We estimate fair value through an evaluation of recent financial performance and projected discounted cash flows using standard industry valuation techniques. In addition to consideration of impairment upon the events or changes in circumstances described above, we regularly evaluate the remaining lives of our long lived assets. If we change our estimate of the remaining lives, we allocate the carrying value of the affected assets over their revised remaining lives.

Note 2. Summary of Significant Accounting Policies (Continued)

Cash and Cash Equivalents. We consider highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents.

Restricted Cash. Restricted cash consists of amounts escrowed for future real estate taxes, insurance, leasing costs, capital expenditures and debt service, as required by certain of our mortgage debts.

Deferred Leasing Costs. Deferred leasing costs include brokerage, legal and other fees associated with the successful negotiation of leases and are amortized on a straight line basis over the terms of the respective leases. Deferred leasing costs totaled $9,395 and $5,684 at December 31, 2012 and 2011, respectively, and accumulated amortization of deferred leasing costs totaled $1,734 and $2,610 at December 31, 2012 and 2011, respectively. Future amortization of deferred leasing costs to be recognized during the current terms of our existing leases as of December 31, 2012 are estimated to be $1,316 in 2013, $1,241 in 2014, $1,177 in 2015, $1,011 in 2016, $651 in 2017 and $2,265 thereafter.

Deferred Financing Fees. Deferred financing fees include issuance or assumption costs related to borrowings and are capitalized and amortized on a straight line basis over the terms of the respective loans. At December 31, 2012 and 2011, deferred financing fees totaled $9,335 and $7,372, respectively, and accumulated amortization of deferred financing fees totaled $3,617 and $1,822, respectively. Future amortization of deferred financing fees to be recognized with respect to our loans as of December 31, 2012 are estimated to be $1,807 in 2013, $1,803 in 2014, $1,540 in 2015, $449 in 2016, $45 in 2017 and $74 thereafter.

Revenue Recognition. Rental income from operating leases is recognized on a straight line basis over the life of lease agreements. We increased (decreased) rental income by $3,553, $1,729 and ($5) to record revenue on a straight line basis during the years ended December 31, 2012, 2011 and 2010, respectively. Rents receivable include $7,455 and $3,901 of straight line rent receivables at December 31, 2012 and 2011, respectively.

Income Taxes. We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended, and, accordingly, we generally will not be subject to federal income taxes provided we distribute our taxable income and meet certain other requirements to qualify as a REIT. We are, however, subject to certain state and local taxes.

Cumulative Other Comprehensive Income. Cumulative other comprehensive income consists of the unrealized gains related to our investment in AIC, as described in Note 5.

Reclassifications. Certain reclassifications have been made to the prior years' financial statements to conform to the current year's presentation.

Use of Estimates. Preparation of these financial statements in conformity with GAAP requires us to make estimates and assumptions that may affect the amounts reported in these consolidated financial statements and related notes. The actual results could differ from these estimates.

Net Income Per Share. We compute net income per common share using the weighted average number of common shares outstanding. We had no common share equivalents during the periods presented.

Segment Reporting. We operate in one business segment: ownership of properties that are primarily leased to government tenants.

Note 3. New Accounting Pronouncements

In January 2012, we adopted Financial Accounting Standards Board, or FASB, Accounting Standards Update No. 2011-04, Amendments to Achieve Common Fair Value Measurements and Disclosure Requirements in U.S. GAAP and IFRS. This update clarified the application of existing fair value measurement requirements. This update also required reporting entities to disclose additional information regarding fair value measurements categorized within Level 3 of the fair value hierarchy. This update was effective for interim and annual reporting periods beginning after December 15, 2011. The implementation of this update did not cause any material changes to the disclosures in, or presentation of, our consolidated financial statements.

In January 2012, we adopted FASB Accounting Standards Update No. 2011-05, Presentation of Comprehensive Income. This update eliminated the option to report other comprehensive income and its components in the statement of shareholders' equity. This update was intended to enhance comparability between entities that report under GAAP and to provide a more consistent method of presenting non-owner transactions that affect an entity's equity. This standard was effective for interim and annual reporting periods beginning after December 15, 2011. The implementation of this update did not cause any changes to our consolidated financial statements other than the presentation of the consolidated statements of comprehensive income.

Note 4. Real Estate Properties

As of December 31, 2012, we owned 84 properties with an undepreciated carrying value, net of impairment losses, of $1,533,468. We generally lease space in our properties on a gross lease or modified gross lease basis pursuant to fixed term operating leases expiring between 2013 and 2027. Certain of our government tenants have the right to terminate their leases before the lease term expires. Our leases generally require us to pay all or some property operating expenses and to provide all or most property management services. During the year ended December 31, 2012, we entered into 48 leases for 1,192,532 rentable square feet for a weighted average (by revenue) lease term of 5.7 years and we made commitments for approximately $13,696 of leasing related costs. We have unspent leasing related obligations of approximately $9,538 as of December 31, 2012.

	$	1,179,656

As of December 31, 2012, government tenants who currently represent approximately 3.3% of our total future minimum lease payments have currently exercisable rights to terminate their leases before the stated expirations. In 2013, 2014, 2015, 2016, 2017, 2018, 2019 and 2020, early termination rights become exercisable by other government tenants who currently represent an additional approximately 3.8%, 3.6%, 0.4%, 12.6%, 5.6%, 2.0%, 7.7% and 1.6% of our total future minimum lease payments, respectively. In addition as of December 31, 2012, 12 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 12 tenants represent approximately 7.1% of our total future minimum lease payments.

During the year ended December 31, 2012, we acquired 12 office properties and one office warehouse property located in nine states for an aggregate purchase price of $213,974, excluding acquisition costs. We allocated the purchase prices of these acquisitions based on the estimated fair values of the acquired assets and assumed liabilities as follows:

(3): Pursuant to the terms of the purchase agreement for this property, the seller is entitled to up to $1,800 of additional purchase consideration based upon the property's 2013 real estate tax assessment. The estimated fair value (based on Level 3 inputs as defined in the fair value hierarchy under GAAP) of this additional consideration at December 31, 2012 of $273 is included in the $18,473 purchase price. Subsequent changes in the fair value of this additional consideration will be recognized in our Consolidated Statement of Income.

Note 4. Real Estate Properties (Continued)

In January 2013, we entered an agreement to sell an office property located in Oklahoma City, OK with 185,881 rentable square feet and a net book value of $7,992 at December 31, 2012. The contract purchase price is $16,300, excluding closing costs.

In February 2013, we entered an agreement to sell an office property located in Tucson, AZ with 31,051 rentable square feet and a net book value of $2,092 (net of a $494 loss on impairment recognized in the fourth quarter of 2012) at December 31, 2012. The contract purchase price is $2,200, excluding closing costs. The net book value of this property at December 31, 2012 reflects the estimated fair value (Level 3 inputs as defined in the fair value hierarchy under GAAP) of the property based upon the contract purchase price less estimated closing costs.

These pending sales are subject to the buyer's satisfactory completion of diligence and other customary closing conditions; accordingly, we cannot assure that we will sell these properties.

Note 5. Related Person Transactions

We have adopted written Governance Guidelines that address the consideration and approval of any related person transactions. Under these 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 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 must be reviewed 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. The 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 transactions with us by RMR employees (other than our Trustees and executive officers) subject to our Code of Business Conduct and Ethics, the employee must seek approval from an executive officer who has no interest in the matter for which approval is being requested.

We have no employees. Personnel and various services we require to operate our business are provided to us by RMR. We have two agreements with RMR to provide management and administrative services to us: (1) a business management agreement, which relates to our business generally, and (2) a property management agreement, which relates to our property level operations.

RMR has approximately 820 employees. One of our Managing Trustees, Mr. Barry Portnoy, is Chairman, majority owner and an employee of RMR. Our other Managing Trustee, Mr. Adam Portnoy, is the son of Mr. Barry Portnoy, and an owner, President, Chief Executive Officer and a director of RMR. Each of our executive officers is also an officer of RMR. CWH's executive officers are officers of RMR. Our Independent Trustees also serve as independent directors or independent trustees of

F-13

GOVERNMENT PROPERTIES INCOME TRUST

(dollars in thousands, except per share data)

Note 5. Related Person Transactions (Continued)

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, and Mr. Adam Portnoy serves as a managing trustee of a majority of those companies, including CWH. In addition, officers of RMR serve as officers of those companies. 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.

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

Our business management agreement with RMR provides for payment to RMR of a business management fee at an annual rate equal to the sum of (a) with respect to properties transferred to us by CWH or another REIT to which RMR provides business management or property management services, or an RMR Managed REIT, 0.5% of the historical cost of such properties to CWH or the RMR Managed REIT (accordingly, the business management fee we pay to RMR in respect of the properties so transferred would be expected to correspond to the reduction in the similar business management fee that CWH or the RMR Managed REIT pays to RMR, such that RMR would not be expected to receive an increase in the business management fees payable in aggregate by us and CWH or the RMR Managed REIT in respect of the transferred properties), plus (b) with respect to other properties we acquire, (i) 0.7% of our aggregate cost of those properties up to and including $250,000, plus (ii) 0.5% of our aggregate cost of those properties in excess of $250,000. In addition, RMR receives an incentive fee equal to 15% of the product of (i) the weighted average of our common shares outstanding on a fully diluted basis during a fiscal year and (ii) the excess, if any, of the FFO Per Share, as defined in the business management agreement, for such fiscal year over the FFO Per Share for the preceding fiscal year. The incentive fee is paid in our common shares and in any year shall not exceed $0.02 multiplied by the weighted average number of our common shares outstanding on a fully diluted basis during such fiscal year. Our common shares for these purposes are valued at the average closing prices of our common shares as reported on the New York Stock Exchange, or NYSE, during the month of December of the fiscal year to which the incentive fee pertains. The business management agreement also provides that, with certain exceptions, if we determine to offer for sale or other disposition any real property that, at such time, is of a type within the investment focus of another RMR Managed REIT, we will first offer that property for purchase or disposition to that RMR Managed REIT and negotiate in good faith for such purchase or disposition. The business management fees we paid to RMR for 2012, 2011 and 2010 were $9,077, $7,741 and $4,453, respectively. These amounts are included in general and administrative expenses in our consolidated financial statements. In March 2012, we issued 39,141 of our common shares to RMR for the incentive fee for 2011, and in March 2013 we expect to issue 20,230 of our common shares to RMR for the incentive fee for 2012. No incentive fee was payable to RMR for 2010.

Our property management agreement with RMR provides for management fees equal to 3.0% of gross collected rents and construction supervision fees equal to 5.0% of construction costs. The aggregate property management and construction supervision fees we paid to RMR for 2012, 2011 and

Note 5. Related Person Transactions (Continued)

2010 were $7,018, $6,321 and $3,785, respectively. These amounts are included in other operating expenses or have been capitalized, as appropriate, in our consolidated financial statements.

RMR also provides internal audit services to us in return for our share of the total internal audit costs incurred by RMR for us and other publicly owned companies managed by RMR and its affiliates, which amounts are subject to approval by our Compensation Committee. Our Audit Committee appoints our Director of Internal Audit. Our pro rata share of RMR's costs of providing this internal audit function was approximately $193, $240 and $211 for 2012, 2011 and 2010, respectively, which amounts are included in general and administrative expenses in our consolidated financial statements. 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 the employment and related expenses of RMR employees who provide on-site property management services and our pro rata share of the staff employed by RMR who perform our internal audit function. Pursuant to our business management agreement, RMR may from time to time negotiate on our behalf with certain 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.

Both our business management agreement with RMR and our property management agreement with RMR 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. On December 10, 2012, we entered amendments to these agreements, which extended the term of the business management agreement until December 31, 2013, clarified certain currently existing policies in the business management agreement and changed certain procedures for the arbitration of disputes pursuant to these agreements.

Under our business management agreement with RMR, we acknowledge that RMR also provides management services to other companies, including CWH, 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 and that, in the event of conflict between us and any such other company, RMR shall in its discretion determine on which party's behalf it shall act. RMR has also agreed not to provide business management services to any other business that is principally engaged in the business of owning properties that are majority leased to or occupied by Governmental Authorities, as defined in the business management agreement, or that are reasonably expected to be majority leased to Governmental Authorities, without the consent of our Independent Trustees.

RMR leases from us approximately 1,400 square feet of office space for one of its regional offices. We earned approximately $32, $31 and $14 in rental income from RMR in 2012, 2011 and 2010, respectively, which we believe was commercially reasonable rent for this office space.

Note 5. Related Person Transactions (Continued)

Under our equity compensation 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 2012, 2011 and 2010, we granted a total of 43,917 restricted shares with an aggregate value of $1,043, 40,850 restricted shares with an aggregate value of $922 and 36,950 restricted shares with an aggregate value of $985, respectively, to such persons, based upon the closing price of our common shares on the NYSE on the dates of grants. One fifth of those restricted shares vested on the grant dates and one fifth vests on each of the next four anniversaries of the grant dates. These share grants to RMR employees are in addition to the fees we pay to RMR. On occasion, we have entered into arrangements with former employees of RMR in connection with the termination of their employment with RMR, providing for the acceleration of vesting of restricted shares previously granted to them under the 2009 Plan.

CWH organized us as a 100% owned subsidiary. In 2009, we completed our IPO, pursuant to which we ceased to be a majority owned subsidiary of CWH. CWH is our largest shareholder and, as of the date of this report, CWH owns 9,950,000 of our common shares, or approximately 18.2% of our outstanding common shares. One of our Managing Trustees, Mr. Barry Portnoy, is a managing trustee of CWH. Our other Managing Trustee, Mr. Adam Portnoy, is a managing trustee and the President of CWH. The purchase agreements between us and CWH described below which 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.

In connection with our IPO, we and CWH entered into a transaction agreement that governs our separation from and relationship with CWH. Pursuant to this transaction agreement, among other things, we and CWH agreed that, so long as CWH owns in excess of 10% of our outstanding common 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 that 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 that are not majority leased to government tenants, unless a majority of CWH's independent trustees who are not also our Trustees have determined not to make the acquisition; and (3) we will have a right of first refusal to acquire any property owned by CWH that CWH determines to divest if the property is then majority leased to a government tenant, 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 also agreed that disputes arising under the transaction agreement may be resolved by binding arbitration.

In June 2010, we purchased 15 properties (approximately 1,900,000 rentable square feet), which were majority leased to government tenants, from CWH for an aggregate purchase price of $231,000, excluding closing 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.

We, RMR, CWH and five other companies to which RMR provides management services each currently own 12.5% of AIC, an Indiana insurance company. All of our Trustees, all of the trustees and directors of the other publicly held AIC shareholders and nearly all of the directors of RMR currently serve on the board of directors of AIC. RMR 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 the affirmative votes of both a majority of our entire Board of Trustees and 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.

As of December 31, 2012, we have invested $5,194 in AIC since we became an equity owner of AIC in December 2009. Although we own less than 20% of AIC, we use the equity method to account for this investment because we believe that we have significant influence over AIC because all of our Trustees are also directors of AIC. Our investment in AIC had a carrying value of $5,747, $5,409 and $5,195 as of December 31, 2012, 2011 and 2010, respectively, which amounts are included in other assets on our consolidated balance sheets. For 2012, 2011 and 2010, we recognized income of $316 and $139 and a loss of $1, respectively, related to our investment in AIC. We and the other shareholders of AIC have purchased property insurance providing $500,000 of coverage pursuant to an insurance program arranged by AIC and with respect to which AIC is a reinsurer of certain coverage amounts. This program was modified and extended in June 2012 for a one year term, and we paid a premium, including taxes and fees, of $410 in connection with that renewal, which amount may be adjusted from time to time as we acquire or dispose of properties that are included in this program. Our annual premiums for this property insurance in 2011 and 2010 were $1,286 and $415, respectively. We are also currently investigating the possibilities to expand our insurance relationships with AIC to include other types of insurance. 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. 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.

Note 6. Concentration

Tenant and Credit Concentration

We define annualized rental income as the annualized contractual base rents from our tenants pursuant to our lease agreements with them as of the measurement date, plus straight line rent adjustments and estimated recurring expense reimbursements to be paid to us, and excluding lease value amortization. The U.S. Government, 10 state governments and the United Nations combined were responsible for approximately 93.9%, 91.9% and 93.0% of our annualized rental income as of December 31, 2012, 2011 and 2010, respectively. The U.S. Government is our largest tenant by annualized rental income and was responsible for approximately 71.7%, 69.6% and 78.2% of our annualized rental income as of December 31, 2012, 2011 and 2010, respectively.

Note 6. Concentration (Continued)

Geographic Concentration

At December 31, 2012, our 84 properties were located in 32 states and the District of Columbia. Properties located in Maryland, California, the District of Columbia, Georgia, New York and Massachusetts were responsible for approximately 12.5%, 12.0%, 10.3%, 9.5%, 8.9% and 6.1% of our annualized rental income as of December 31, 2012, respectively.

Note 7. Indebtedness

At December 31, 2012 and 2011, our outstanding indebtedness consisted of the following:

	December 31,

	2012		2011
Unsecured revolving credit facility, due in 2015	$	49,500	$	345,500
Unsecured term loan, due in 2017		350,000		—
Mortgage note payable, 5.73% interest rate, including unamortized premium of $621, due in 2015⁽¹⁾		49,274		50,118
Mortgage note payable, 6.21% interest rate, due in 2016⁽¹⁾		24,441		24,713
Mortgage note payable, 7.00% interest rate, including unamortized premium of $878, due in 2019⁽¹⁾		10,247		10,559

	$	492,627	$	440,883

⁽¹⁾: We assumed these mortgages in connection with our acquisition of certain properties. The stated interest rates for these mortgage debts are the contractually stated rates. We recorded the assumed mortgages at estimated fair value on the date of acquisition and we are amortizing the fair value premiums, if any, to interest expense over the respective terms of the mortgages to reduce interest expense to the estimated market interest rates as of the date of acquisition.

We have a $550,000 unsecured revolving credit facility that is available for general business purposes, including acquisitions. The maturity date of our revolving credit facility is October 19, 2015 and, subject to the payment of an extension fee and meeting certain other conditions, includes an option for us to extend the stated maturity date of our revolving credit facility by one year to October 19, 2016. In addition, our revolving credit facility includes a feature under which maximum borrowings may be increased to up to $1,100,000 in certain circumstances. Borrowings under our revolving credit facility bear interest at a rate of LIBOR plus a spread of 150 basis points. We also pay a facility fee of 35 basis points per annum on the total amount of lending commitments under our revolving credit facility. Both the interest rate spread and the facility fee are subject to adjustment based upon changes to our credit ratings. As of December 31, 2012, the interest rate payable on borrowings under our revolving credit facility was 1.71%, and the weighted average annual interest rate for borrowings under our revolving credit facility was 1.75% and 2.19% for the years ended December 31, 2012 and December 31 2011, respectively. As of December 31, 2012 we had $49,500 outstanding and $500,500 available under our revolving credit facility.

In January 2012, we entered into a five year $350,000 unsecured term loan. Our term loan matures on January 11, 2017, and is prepayable without penalty at any time. In addition, our term loan includes a feature under which maximum borrowings may be increased to up to $700,000 in certain circumstances. Our term loan bears interest at a rate of LIBOR plus a spread, which was 175 basis points as of December 31, 2012. The interest rate spread is subject to adjustment based upon changes to our credit ratings. As of December 31, 2012, the interest rate for the amount outstanding under our

F-18

(dollars in thousands, except per share data)

Note 7. Indebtedness (Continued)

term loan was 1.96% and the weighted average interest rate for the amount outstanding under our term loan was 1.99% for the period from January 12, 2012 to December 31, 2012.

At December 31, 2012, five of our properties with an aggregate net book value of $122,682 were secured by four mortgage notes. We assumed these mortgages in connection with certain of our acquisitions. Our mortgage notes are non-recourse and do not contain any material financial covenants.

The required principal payments due during the next five years and thereafter under all our outstanding debt as of December 31, 2012 are as follows:


2013	$	1,933
2014		2,072
2015		98,191
2016		24,708
2017		351,308
Thereafter		12,265

Note 8. Fair Value of Financial Instruments

Our financial instruments at December 31, 2012, include cash and cash equivalents, restricted cash, rents receivable, mortgage notes payable, accounts payable, our revolving credit facility and our term loan, amounts due to related persons, other accrued expenses and security deposits. At December 31, 2012, the fair values of our financial instruments approximated their carrying values in our consolidated financial statements, except as follows:

	Carrying Amount		Fair Value

Mortgage note payable, 5.73% interest rate, including unamortized premium of $621, due in 2015	$	49,274	$	51,117
Mortgage note payable, 6.21% interest rate, due in 2016		24,441		27,109
Mortgage note payable, 7.00% interest rate, including unamortized premium of $878, due in 2019		10,247		11,126
Mortgage note payable, 8.15% interest rate, including unamortized premium of $651, due in 2021		9,165		10,460

	$	93,127	$	99,812

We estimate the fair values of our mortgage notes payable by using discounted cash flow analyses and currently prevailing market terms as of the measurement date (Level 3 inputs as defined in the fair value hierarchy under GAAP). Because our inputs are unobservable, our estimated fair value may differ materially from the actual fair value.

Note 9. Shareholders' Equity

Share Awards

We have common shares available for issuance under the terms of our 2009 Plan. As described in Note 5, we awarded common shares to our officers and certain employees of RMR in 2010, 2011 and 2012. We also awarded to each of our Trustees 2,000 common shares in 2012 with an aggregate market value of $224 ($45 per Trustee), 2,000 common shares in 2011 with an aggregate market value of $256 ($51 per Trustee) and 1,500 common shares in 2010 with an aggregate market value of $208 ($42 per Trustee) as part of their annual compensation, based upon the closing price of our common shares on the NYSE on the date of grant. The common shares awarded to our Trustees vested immediately. The common shares awarded to our officers and certain employees of RMR vest in five equal annual installments beginning on the date of grant. We include the value of awarded shares in general and administrative expenses at the time the awards vest.

A summary of shares granted and vested under the terms of our 2009 Plan for the years ended December 31, 2012, 2011 and 2010, is as follows:

	2012					2011					2010

As of December 31, 2012, the estimated future compensation expense for the unvested shares was $1,824 based on the closing share price of our common shares on the NYSE on December 31, 2012 of $23.97. The weighted average period over which the compensation expense will be recorded is approximately 22 months. During the years ended December 31, 2012, 2011 and 2010, we recorded $1,598, $1,646 and $742, respectively, of compensation expense related to our 2009 Plan.

At December 31, 2012, 1,781,112 of our common shares remain available for issuance under the 2009 Plan.

On February 24, 2012, May 24, 2012 and August 22, 2012 we paid a $0.42 per share distribution to our common shareholders. On November 21, 2012 we paid a $0.43 per share distribution to our common shareholders. On January 10, 2013, we declared a distribution payable to common shareholders of record on January 25, 2013 in the amount of $0.43 per share. We expect to pay this distribution on or about February 22, 2013.
