PART I

Item 1.    Business.

General

        We are a self-administered and self-managed real estate investment trust, also known as a REIT. We were incorporated under the laws of the State of Maryland on December 20, 1982. We acquire, own and manage a geographically diversified portfolio of retail (including furniture and office supply stores), industrial, office, flex, health and fitness and other properties, a substantial portion of which are under long-term leases. Substantially all of our leases are "net leases" and ground leases under which the tenant is typically responsible for real estate taxes, insurance and ordinary maintenance and repairs. As of December 31, 2010, we owned 84 properties, two of which are vacant, and one of which is a 50% tenancy in common interest, and participated in four joint ventures that own four properties. Our properties and the properties owned by our joint ventures are located in 29 states and have an aggregate of approximately 5.1 million square feet of space (including approximately 106,000 square feet of space at the property in which we own a tenancy in common interest and approximately 1.1 million square feet of space at properties owned by the joint ventures in which we participate).

        As of December 31, 2010:

•

our 2011 contractual rental income (as defined) was approximately $41.6 million;



•

the occupancy rate of properties owned by us was 98.5% based on square footage (including the property in which we own a tenancy in common interest and properties tenanted by debtors in bankruptcy proceedings);



•

the occupancy rate of properties owned by our joint ventures was 100% based on square footage; and



•

the weighted average remaining term of the leases generating our 2011 contractual rental income is 9.2 years and ten years for the leases at properties owned by our joint ventures.

        Our 2011 contractual rental income includes, after giving effect to any abatements, concessions or adjustments (i) rental income that is payable to us in 2011 under leases existing at December 31, 2010, excluding rental income from two tenants that are debtors in bankruptcy proceedings and (ii) rental income that is payable to us in 2011 on our tenancy in common interest.

        Our share of the rental income payable to our joint ventures in 2011 will be approximately $1.3 million; such sum is not included in 2011 contractual rental income.

        We refer to the mortgages on our properties as being "non-recourse (subject to standard carve-outs)." The term "standard carve-outs" refers to recourse items to an otherwise non-recourse mortgage and are customary to mortgage financing. While carve-outs vary from lender to lender and transaction to transaction, the carve-outs may include, among other things, environmental liabilities, the sale, financing or encumbrance of the property in violation of loan documents, damage to property as a result of intentional misconduct or gross negligence, failure to pay valid taxes and other claims which could create liens on property and the conversion of security deposits, insurance proceeds or condemnation awards.

Recent Developments

        In 2010, we acquired 14 properties for $72.3 million (including the assumption of an aggregate of $33.6 million in mortgage debt). The properties are located in Pennsylvania, Connecticut, Missouri, Texas and New York and account for approximately $5.8 million or 13.9% of our 2011 contractual rental income. We also sold two properties in the third quarter of 2010 for an aggregate of $4.1 million

and realized a gain of approximately $235,000. The properties sold accounted for $165,000 of income from discontinued operations in 2010.

        In May 2010 (effective as of March 2010) and January 2011, we amended our revolving credit line. After giving effect to these amendments, the maturity of our credit line was extended until March 2013, we are permitted to borrow up to $55 million and the interest rate was set at the greater of (i) 90 day LIBOR plus 3% and (ii) 6%. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations—Credit Line" for further information on our credit line.

        In February 2011, we sold 2,700,000 shares of our common stock in a public offering for net proceeds of approximately $40.6 million. We used the proceeds to repay mortgage indebtedness of $7.7 million having a weighted average interest rate of 7.9% and to reduce by $26.2 million the amount outstanding under our revolving line of credit. We intend to use the remaining balance of such proceeds for general corporate purposes, including future property acquisitions.

        On February 18, 2011, Robb & Stucky Limited LLLP, a retail furniture operator which rents one property from us in Plano, Texas, and accounted for approximately $882,000 or 2.1% of our 2010 rental income, filed for bankruptcy protection. As a result, in the fourth quarter of 2010 we (i) took a charge of approximately $656,000 relating to the reversal of the straight-lining of rent payments and net lease intangibles that were recorded during the term of the lease to December 31, 2010 and (ii) accrued $288,000 for 2010 real estate tax expense associated with the property. We also did not collect, and may be unable to collect, an aggregate of approximately $349,000 of rent owed for December 2010 through February 2011. We have not taken an impairment charge with respect to this property. The taking of such charge, if any is required, would reduce our net income in the period in which such charge is taken.

Acquisition Strategies

        We seek to acquire properties throughout the United States that have locations, demographics and other investment attributes that we believe to be attractive. We believe that long-term leases provide a predictable income stream over the term of the lease, making fluctuations in market rental rates and in real estate values less significant to achieving our overall investment objectives. Our goal is to acquire properties that are subject to long-term net or ground leases that include periodic contractual rental increases or rent increases based on increases in the consumer price index. Periodic contractual rental increases provide reliable increases in future rent payments and rent increases based on the consumer price index provide protection against inflation. Historically, long-term leases have made it easier for us to obtain longer-term, fixed-rate mortgage financing with principal amortization, thereby moderating the interest rate risk associated with financing or refinancing our property portfolio by reducing the outstanding principal balance over time. We may, however, acquire a property that is subject to a short-term lease when we believe the property represents a good opportunity for recurring income and residual value. Although we regard the acquisition of properties subject to net and ground leases as an important aspect of our investment strategy, we have expanded our focus to include the acquisition of community shopping centers anchored by national or regional tenants. Typically, we would pay substantially all operating expenses at these community shopping centers, a significant portion of which will be reimbursed by the tenants pursuant to their leases.

        Generally, we hold the properties we acquire for an extended period of time. Our investment criteria are intended to identify properties from which increased asset value and overall return can be realized from an extended period of ownership. Although our investment criteria favor an extended period of ownership, we will dispose of a property if we regard the disposition of the property as an opportunity to realize the overall value of the property sooner or to avoid future risks by achieving a determinable return from the property.

Table of Contents

        We identify properties through the network of contacts of our senior management and our affiliates, which includes real estate brokers, private equity firms, banks and law firms. In addition, we attend industry conferences and engage in direct solicitations.

        Our charter documents do not limit on the number of properties in which we may invest, the amount or percentage of our assets that may be invested in any specific property or property type, or on the concentration of investments in any region in the United States. We do not intend to acquire properties located outside of the United States. We will continue to form entities to acquire interests in real properties, either alone or with other investors, and we may acquire interests in joint ventures or other entities that own real property.

        It is our policy, and the policy of our affiliated entities, that any investment opportunity presented to us or to any of our affiliated entities that involves primarily the acquisition of a net leased property, a ground lease or a community shopping center, will first be offered to us and may not be pursued by any of our affiliated entities unless we decline the opportunity.

Investment Evaluation

        In evaluating potential investments, we consider, among other criteria, the following:

•

the ability of a tenant, if a net leased property, or major tenants, if a shopping center, to meet operational needs and lease obligations recognizing the current economic climate;



•

the current and projected cash flow of the property;



•

the estimated return on equity to us;



•

an evaluation of the property and improvements, given its location and use;



•

local demographics (population and rental trends);



•

the terms of tenant leases, including the relationship between current rents and market rents;



•

the projected residual value of the property;



•

potential for income and capital appreciation;



•

occupancy of and demand for similar properties in the market area; and



•

alternate use for the property at lease termination.

Our Business Objective

        Our business objective is to maintain and increase the cash available for distribution to our stockholders by:

•

identifying opportunistic property acquisitions consistent with our portfolio and our acquisition strategies;



•

obtaining mortgage indebtedness on favorable terms and maintaining access to capital to finance property acquisitions;



•

monitoring and maintaining our portfolio, including tenant negotiations and lease amendments with tenants having financial difficulty; and



•

managing assets effectively, including lease extensions and opportunistic property sales.

Table of Contents

Typical Property Attributes

        The properties in our portfolio and owned by our joint ventures typically have the following attributes:

•

Net or ground leases.  Substantially all of the leases are net and ground leases under which the tenant is typically responsible for real estate taxes, insurance and ordinary maintenance and repairs. We believe that investments in net and ground leased properties offer more predictable returns than investments in properties that are not net or ground leased;



•

Long-term leases.  Substantially all of our leases are long-term leases. Excluding leases relating to properties owned by our joint ventures, leases representing approximately 71% of our 2011 contractual rental income expire after 2016, and leases representing approximately 40% of our 2011 contractual rental income expire after 2020; and



•

Scheduled rent increases.  Leases representing approximately 96% of our 2011 contractual rental income provide for either periodic contractual rent increases or rent increases based on the consumer price index. A lease with respect to a property owned by one joint venture provides for a rent increase based on the consumer price index.

Our Tenants

        The following table sets forth information about the diversification of our tenants by industry sector as of December 31, 2010:

4

Table of Contents

        Most of our retail tenants operate on a national basis and include, among others, Barnes & Noble, Best Buy, CarMax, CVS, Kohl's, Marshalls, Mens' Wearhouse, Office Depot, Office Max, Party City, PetSmart, The Sports Authority, Walgreens, Wendy's and Whole Foods and some of our tenants operate on a regional basis, including Giant Food Stores and Haverty Furniture Companies.

Our Leases

        Substantially all of our leases are net or ground leases (including the leases entered into by our joint ventures) under which the tenant, in addition to its rental obligation, typically is responsible for expenses attributable to the operation of the property, such as real estate taxes and assessments, water and sewer rents and other charges. The tenant is also generally responsible for maintaining the property and for restoration following a casualty or partial condemnation. The tenant is typically obligated to indemnify us for claims arising from the property and is responsible for maintaining insurance coverage for the property it leases and naming us an additional insured. Under some net leases, we are responsible for structural repairs, including foundation and slab, roof repair or replacement and restoration following a casualty event, and at several properties we are responsible for certain expenses related to the operation and maintenance of the property.

        Our typical lease provides for contractual rent increases periodically throughout the term of the lease or for rent increases pursuant to a formula based on the consumer price index. Some of our leases provide for minimum rents supplemented by additional payments based on sales derived from the property subject to the lease. Such additional payments were not a material part of our 2010 rental revenues and are not expected to be a material part of our 2011 rental revenues.

        Our policy has been to acquire properties that are subject to existing long-term leases or to enter into long-term leases with our tenants. Our leases generally provide the tenant with one or more renewal options.

Table of Contents

        The following table sets forth scheduled lease expirations of leases for our properties (excluding joint venture properties) as of December 31, 2010:

Financing, Re-Renting and Disposition of Our Properties

        Our charter documents do not limit the level of debt we may incur. Our revolving credit facility matures on March 31, 2013 and, among other things, limits total debt that we may incur to 70% of the value of our properties (as determined pursuant to the credit agreement). We borrow funds on a secured and unsecured basis and intend to continue to do so in the future.

        We also mortgage specific properties on a non-recourse basis (subject to standard carve-outs) to enhance the return on our investment in a specific property. The proceeds of mortgage loans may be used for property acquisitions, investments in joint ventures or other entities that own real property, to reduce bank debt and for working capital purposes. The proceeds of our credit facility may be used to payoff existing mortgages, fund the acquisition of additional properties, or to invest in joint ventures. Net proceeds received from refinancing of properties are required to be used to repay amounts outstanding under our credit facility if proceeds from the credit facility were used to purchase or refinance the property.

        With respect to properties we acquire on a free and clear basis, we usually seek to obtain long-term fixed-rate mortgage financing, when available at acceptable terms, shortly after the acquisition of such property to avoid the risk of movement of interest rates and fluctuating supply and demand in the mortgage markets. We also will acquire a property that is subject to (and will assume) a fixed-rate mortgage. Substantially all of our mortgages provide for amortization of part of the principal balance during the term, thereby reducing the refinancing risk at maturity. Some of our properties may be financed on a cross-defaulted or cross-collateralized basis, and we may collateralize a single financing with more than one property.

Table of Contents

        Despite the imposition during the past few years of more stringent lending standards and dislocations in the mortgage securitization markets, we were able in 2010 to obtain some mortgage financing on acceptable terms. As a result, excluding mortgage debt of $33.6 million we assumed in connection with our 2010 acquisitions, we obtained new mortgages in aggregate principal amount of $7.5 million.

        After termination or expiration of any lease relating to any of our properties, we will seek to re-rent or sell such property in a manner that will maximize the return to us, considering, among other factors, the income potential and market value of such property. We acquire properties for long-term investment for income purposes and do not typically engage in the turnover of investments. We will consider the sale of a property if a sale appears advantageous in view of our investment objectives. We may take back a purchase money mortgage as partial payment in lieu of cash in connection with any sale and may consider local custom and prevailing market conditions in negotiating the terms of repayment. If there is a substantial tax gain, we may seek to enter into a tax deferred transaction and reinvest the proceeds in another property. It is our policy to use any cash realized from the sale of properties, net of any distributions to stockholders, to pay down amounts due under our credit facility, if any, and for the acquisition of additional properties.

Our Joint Ventures

        As of December 31, 2010, we are a joint venture partner in four joint ventures that own an aggregate of four properties, and have an aggregate of approximately 1.1 million rentable square feet of space. Three of the properties are retail properties and one is an industrial property. We own a 50% equity interest in all four of the joint ventures. We are designated as the sole "managing member" or "manager" under the operating agreements of two of these joint ventures; however, we do not exercise substantial operating control over these entities. At December 31, 2010, our investment in unconsolidated joint ventures was approximately $4.8 million.

        Based on existing leases, we anticipate that our share of rental income payable to our joint ventures in 2011 will be approximately $1.3 million. The leases for two properties (each of which is owned by one of our joint ventures), are expected to contribute 92.9% of the aggregate projected rental income payable to all of our joint ventures in 2011 and expire in 2021 and 2022.

Competition

        We face competition for the acquisition of properties from a variety of investors, including domestic and foreign corporations and real estate companies, financial institutions, insurance companies, pension funds, investment funds, other REITs and individuals, some of which have significant advantages over us, including a larger, more diverse group of properties and greater financial and other resources than we have.

Our Structure

        Five employees, Patrick J. Callan, Jr., our president and chief executive officer, Lawrence G. Ricketts, Jr., our executive vice president and chief operating officer, and three others, devote all of their business time to our company. Our other executive, administrative, legal, accounting and clerical personnel share their services on a part-time basis with us and other affiliated entities that share our executive offices.

        We entered into a compensation and services agreement with Majestic Property Management Corp., effective as of January 1, 2007. Majestic Property Management Corp. is wholly-owned by our chairman of the board and it provides compensation to certain of our executive officers. Pursuant to this agreement, we pay an annual fee to Majestic Property Management Corp. and Majestic Property Management Corp. assumes our obligations under a shared services agreement, and provides us with

7

Table of Contents

the services of all affiliated executive, administrative, legal, accounting and clerical personnel that we use on a part time basis, as well as certain property management services, property acquisition, sales and leasing and mortgage brokerage services. The annual fees we pay to Majestic Property Management Corp. are negotiated each year by us and Majestic Property Management Corp., and are approved by our audit committee and independent directors.

        In 2010, we incurred a fee of $2,225,000 to Majestic Property Management Corp. under the compensation and services agreement. Pursuant to this agreement, we paid $2,213,000 of the fee and the remainder of the fee, $12,000, was offset by the $12,000 paid to Majestic Property Management Corp. by one of our joint ventures. In addition, we paid Majestic Property Management Corp. $175,000 for our share of all direct office expenses, including, among other expenses, rent, telephone, postage, computer services and internet usage. We also paid our chairman a fee of $250,000 in 2010 in accordance with the agreement. See Note 10 to our consolidated financial statements for information regarding equity awards to individual performing services on our behalf.

        We believe that the compensation and services agreement allows us to benefit from access to, and from the services of, a group of senior executives with significant knowledge and experience in the real estate industry and our company and its activities. If not for this agreement, we believe that a company of our size would not have access to the skills and expertise of these executives at the cost that we have incurred and will incur in the future. For a description of the background of our management, please see the information under the heading "Executive Officers" in Part I of this Annual Report.

        In addition to the other information contained or incorporated by reference in this Form 10-K, readers should carefully consider the following risk factors:

Risks Related to Our Business

We may incur negative cash flow from our property tenanted by Robb & Stucky and we may take an impairment charge which would adversely affect our net income.

        On February 18, 2011, Robb & Stucky, a retail tenant which rents one property from us in Plano, Texas, and accounted for approximately $882,000 or 2.1% of our 2010 rental income, filed for bankruptcy protection under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the Middle District of Florida (Case No. 8:11-bk-02801-CED). This property has a book value on our balance sheet as of December 31, 2010 of approximately $12 million and is encumbered by a $9 million non-recourse mortgage (subject to standard carve-outs) maturing in 2016. In the fourth quarter of 2010, we took a charge of approximately $656,000 relating to the reversal of the straight-lining of rent payments and net lease intangibles that was recorded over the term of the lease to December 31, 2010, and accrued real estate expense of $288,000 relating to unpaid 2010 real estate taxes. We also did not collect the $116,000 per month of rental payments owed for December 2010 through February 2011. If and until a replacement tenant is found on acceptable terms, we sell the property or surrender the property to the mortgagee, we may incur negative cash flow with respect to such property.

        We have not taken an impairment charge with respect to this property and the taking of such charge, if any is required, would reduce our net income in the period in which it is taken.

If our tenants default, if we are unable to re-rent properties upon the expiration of our leases, or if a significant number of tenants are granted rent relief, our revenues will be reduced and we would incur additional costs.

        Substantially all of our revenues are derived from rental income paid by tenants at our properties. The recent economic crisis and the uncertain economic climate has effected a number of our tenants. A deterioration of economic conditions could result in tenants defaulting on their obligations, fewer tenants renewing their leases upon the expiration of their terms or tenants seeking rent relief or other accommodations or renegotiation of their leases. As a result of any of these events, our revenues would decline. At the same time, we would remain responsible for the payment of our mortgage obligations and would become responsible for the operating expenses related to our properties, including, among other things, real estate taxes, maintenance and insurance. In addition, we would incur expenses in enforcing our rights as landlord. Even if we find replacement tenants or renegotiate leases with current tenants, the terms of the new or renegotiated leases, including the cost of required renovations or concessions to tenants, or the expense of the reconfiguration of a single tenancy property for use by multiple tenants, may be less favorable than current lease terms and could reduce the amount of cash available to meet expenses and pay distributions.

Approximately 60% of our 2010 rental revenue was derived from tenants operating in the retail industry, which has been particularly weakened during the recent economic crisis, and the inability of those tenants to pay rent would significantly reduce our revenues.

        Approximately 60% of our rental revenues (excluding rental revenues from our joint ventures) for 2010 was derived from retail tenants and approximately 60% of our 2011 contractual rental income is expected to be derived from retail tenants, including 13.8% and 12.5%, from tenants engaged in retail furniture and office supply operations, respectively. The recent economic crisis and recession has caused a significant decline in consumer spending on retail goods.

10

Table of Contents

        If economic conditions do not continue to improve, it could cause our retail tenants to fail to meet their lease obligations, including rental payment delinquencies, which would have an adverse effect on our results of operations, liquidity and financial condition, including making it more difficult for us to satisfy our operating and debt service requirements, make capital expenditures and make distributions to our stockholders.

Approximately 38% of our 2010 revenues and 36% of our 2011 contractual rental income is derived from five tenants. The default, financial distress or failure of any of these tenants could significantly reduce our revenues.

        Haverty Furniture Companies, Inc., Office Depot, Inc., Ferguson Enterprises, Inc., DSM Nutritional Products, Inc., and L-3 Communications Corp., accounted for approximately 11.6%, 10.6%, 5.5%, 5.8% and 4.2%, respectively, of our rental revenues (excluding rental revenues from our joint ventures) for 2010, and account for 10.4%, 10.7%, 5.6%, 5.0% and 4.6%, respectively, of our 2011 contractual rental income. The default, financial distress or bankruptcy of any of these tenants could cause interruptions in the receipt of, or the loss of, a significant amount of rental revenues and would require us to pay operating expenses currently paid by the tenant. This could also result in the vacancy of the property or properties occupied by the defaulting tenant, which would significantly reduce our rental revenues and net income until the re-rental of the property or properties, and could decrease the ultimate sale value of the property.

Declines in the value of our properties could result in additional impairment charges.

        The recent economic downturn caused a decline in real estate values generally throughout the country. If we are presented with indications of an impairment in the value of a particular property or group of properties, we will be required to evaluate any such property or properties. If we determine that any of our properties at which indicators of impairment exist have a value which is below the net book value of such property, we will be required to recognize an impairment charge for the difference between the fair value and the book value during the quarter in which we make such determination. In addition, we may incur losses from time to time if we dispose of properties for sales prices that are less than our book value.

Competition that traditional retail tenants face from on-line retail sales could adversely affect our business.

        Our retail tenants face increasing competition from online retailers. Online retailers may be able to provide customers with better pricing and the ease and comfort of shopping from their home or office. Internet sales have been obtaining an increasing percentage of retail sales over the past few years and this trend is expected to continue. The continued growth of online sales could decrease the need for traditional retail outlets and reduce retailers' space and property requirements. This could adversely impact our ability to rent space at our retail properties and increase competition for retail tenants thereby reducing the rent we would receive at these properties and adversely affecting our results of operations and financial condition.

If we are unable to refinance our mortgage loans at maturity, we may be forced to sell properties at disadvantageous terms, which would result in the loss of revenues and in a decline in the value of our portfolio.

        We had, as of December 31, 2010, $215.3 million in mortgage debt outstanding, all of which is non-recourse (subject to standard carve-outs), our ratio of mortgage debt to total assets was 48.4% and our joint ventures had $17.4 million in total mortgage indebtedness (all of which is non-recourse, subject to standard carve-outs). The risks associated with our mortgage debt and the mortgage debt of our joint ventures include the risk that cash flow from properties securing the mortgage indebtedness and our available cash and cash equivalents and short-term investments will be insufficient to meet required payments of principal and interest.

11

Table of Contents

        Generally, only a small portion of the principal of our mortgage indebtedness will be repaid prior to maturity and we do not plan to retain sufficient cash to repay such indebtedness at maturity. Accordingly, to meet these obligations if they cannot be refinanced at maturity, we will have to use funds available under our credit facility, if any, and our available cash and cash equivalents and short-term investments to pay our mortgage debt or seek to raise funds through the financing of unencumbered properties, sale of properties or the issuance of additional equity. Between January 1, 2011 and December 31, 2013, approximately $35.7 million of our mortgage debt matures (excluding mortgage debt of $7.7 million repaid in February 2011 and mortgage debt of our joint ventures). With respect to our joint ventures, approximately $13.4 million and $1.7 million of mortgage debt matures in 2015 and 2016, respectively. If we (or our joint ventures) are not successful in refinancing or extending existing mortgage indebtedness or financing unencumbered properties, selling properties on favorable terms or raising additional equity, our cash flow (or the cash flow of a joint venture) will not be sufficient to repay all maturing mortgage debt when payments become due, and we (or a joint venture) may be forced to dispose of properties on disadvantageous terms or convey properties secured by mortgages to the mortgagees, which would lower our revenues and the value of our portfolio.

        Additionally, we may find that the value of a property could be less than the mortgage secured by such property. In such instance, we may seek to renegotiate the terms of the mortgage, or to the extent that our loan is non-recourse and the terms of the mortgage cannot be satisfactorily renegotiated, forfeit the property by conveying it to the mortgagee and writing off our investment.

If our borrowings increase, the risk of default on our repayment obligations and our debt service requirements will also increase.

        The terms of our revolving credit facility limit our ability to incur indebtedness, including limiting the total indebtedness that we may incur to an amount equal to 70% of the value (as defined in the credit agreement) of our properties. Increased leverage could result in increased risk of default on our payment obligations related to borrowings and in an increase in debt service requirements, which could reduce our net income and the amount of cash available to meet expenses and to make distributions to our stockholders.

If a significant number of our tenants default or fail to renew expiring leases, or we take impairment charges against our properties, a breach of our revolving credit facility could occur.

        Our revolving credit facility includes financial covenants that require us to maintain certain financial ratios and requirements. If our tenants default under their leases with us or fail to renew expiring leases, generally accepted accounting principles may require us to recognize impairment charges against our properties, and our financial position could be adversely affected causing us to be in breach of the financial covenants contained in our credit facility.

        Failure to meet interest and other payment obligations under our revolving credit facility or a breach by us of the covenants to maintain the financial ratios would place us in default under our credit facility, and, if the banks called a default and required us to repay the full amount outstanding under the credit facility, we might be required to rapidly dispose of our properties, which could have an adverse impact on the amounts we receive on such disposition. If we are unable to dispose of our properties in a timely fashion to the satisfaction of the banks, the banks could foreclose on that portion of our collateral pledged to the banks, which could result in the disposition of our properties at below market values. The disposition of our properties at below our carrying value would adversely affect our net income, reduce our stockholders' equity and adversely affect our ability to pay distributions to our stockholders.

Impairment charges against owned real estate may not be adequate to cover actual losses.

        Impairment charges are based on an evaluation of known risks and economic factors. The determination of an appropriate level of impairment charges is an inherently difficult process and is based on numerous assumptions. The amount of impairment charges of real estate is susceptible to changes in economic, operating and other conditions that are largely beyond our control. Any impairment charges that we may take may not be adequate to cover actual losses and we may need to take additional impairment charges in the future. Actual losses and additional impairment charges in the future could materially affect our results of operations.

If credit markets tighten, it may be more difficult for us to secure financing, which may limit our ability to finance or refinance our real estate properties, reduce the number of properties we can acquire, and adversely affect your investment.

        From 2008 to 2009, due to the national economic recession and credit crisis and the resulting caution by lenders in evaluating and underwriting new transactions, there was a significant tightening of the credit markets. While we believe that in 2010 access to credit markets eased, this trend may not continue or it may be reversed. Reduced access to credit markets may make it difficult for us to secure mortgage debt, possibly limiting the mortgage debt available on real estate properties we wish to acquire, and even reducing the number of properties we can acquire. Even in the event that we are able to secure mortgage debt on, or otherwise finance our real estate properties, due to increased costs associated with securing financing and other factors beyond our control, we may be unable to refinance the entire outstanding loan balance or be subject to unfavorable terms (such as higher loan fees, interest rates and periodic payments) if we do refinance the loan balance. Either of these results could reduce any income from those properties and reduce cash available for distribution, which may adversely affect the investment goals of our stockholders.

Our net leases and our ground leases require us to pay property related expenses that are not the obligations of our tenants.

        Under the terms of substantially all of our net leases, in addition to satisfying their rent obligations, our tenants are responsible for the payment of real estate taxes, insurance and ordinary maintenance and repairs. However, under the provisions of certain net and ground leases, we are required to pay some expenses, such as the costs of environmental liabilities, roof and structural repairs, insurance, certain non-structural repairs and maintenance. If our properties incur significant expenses that must be paid by us under the terms of our leases, our business, financial condition and results of operations will be adversely affected and the amount of cash available to meet expenses and to make distributions to holders of our common stock may be reduced.

Uninsured and underinsured losses may affect the revenues generated by, the value of, and the return from a property affected by a casualty or other claim.

        Substantially all of our tenants obtain, for our benefit, comprehensive insurance covering our properties in amounts that are intended to be sufficient to provide for the replacement of the improvements at each property. However, the amount of insurance coverage maintained for any property may not be sufficient to pay the full replacement cost of the improvements at the property following a casualty event. In addition, the rent loss coverage under the policy may not extend for the full period of time that a tenant may be entitled to a rent abatement as a result of, or that may be required to complete restoration following, a casualty event. In addition, there are certain types of losses, such as those arising from earthquakes, floods, hurricanes and terrorist attacks, that may be uninsurable or that may not be economically insurable. Changes in zoning, building codes and ordinances, environmental considerations and other factors also may make it impossible or impracticable for us to use insurance proceeds to replace damaged or destroyed improvements at a

13

Table of Contents

property. If restoration is not or cannot be completed to the extent, or within the period of time, specified in certain of our leases, the tenant may have the right to terminate the lease. If any of these or similar events occur, it may reduce our revenues, the value of, or our return from, an affected property.

Our revenues and the value of our portfolio are affected by a number of factors that affect investments in real estate generally.

        We are subject to the general risks of investing in real estate. These include adverse changes in economic conditions and local conditions such as changing demographics, retailing trends and traffic patterns, declines in the rental rates, changes in the supply and price of quality properties and the market supply and demand of competing properties, the impact of environmental laws, security concerns, prepayment penalties applicable under mortgage financings, changes in tax, zoning, building code, fire safety and other laws and regulations, the type of insurance coverage available in the market, and changes in the type, capacity and sophistication of building systems. Approximately 60%, 12.9% and 11.0% of our 2011 contractual rental income is expected to come from retail, industrial, and office tenants, respectively, and we are vulnerable to economic declines that negatively impact these sectors of the economy, which could have an adverse effect on our results of operations, liquidity and financial condition.

Our revenues and the value of our portfolio are affected by a number of factors that affect investments in leased real estate generally.

        We are subject to the general risks of investing in leased real estate. These include the non-performance of lease obligations by tenants, leasehold improvements that will be costly or difficult to remove should it become necessary to re-rent the leased space for other uses, covenants in certain retail leases that limit the types of tenants to which available space can be rented (which may limit demand or reduce the rents realized on re-renting), rights of termination of leases due to events of casualty or condemnation affecting the leased space or the property or due to interruption of the tenant's quiet enjoyment of the leased premises, and obligations of a landlord to restore the leased premises or the property following events of casualty or condemnation. The occurrence of any of these events could adversely impact our results of operations, liquidity and financial condition.

Real estate investments are relatively illiquid and their values may decline.

        Real estate investments are relatively illiquid. Therefore, we will be limited in our ability to reconfigure our real estate portfolio in response to economic changes. We may encounter difficulty in disposing of properties when tenants vacate either at the expiration of the applicable lease or otherwise. If we decide to sell any of our properties, our ability to sell these properties and the prices we receive on their sale may be affected by many factors, including the number of potential buyers, the number of competing properties on the market and other market conditions, as well as whether the property is leased and if it is leased, the terms of the lease. As a result, we may be unable to sell our properties for an extended period of time without incurring a loss, which would adversely affect our results of operations, liquidity and financial condition.

The concentration of our properties in certain regions may make our revenues and the value of our portfolio vulnerable to adverse changes in local economic conditions.

        The properties we own may be located in the same or a limited number of geographic regions. Approximately 27% of our rental income (excluding our share of rental income from our joint ventures) for 2010 was, and approximately 26% of our 2011 contractual rental income will be, derived from properties located in Texas and New York. At December 31, 2010, 24% of the depreciated book value of our real estate investments (excluding our share of the assets from our joint ventures) were

14

Table of Contents

located in Texas and New York. As a result, a decline in the economic conditions in these regions, or in regions where our properties may be concentrated in the future, may have an adverse effect on the rental and occupancy rates for, and the property values of, these properties, which could lead to a reduction in our rental income and in the results of operations.

If we reduce our dividend, the market value of our common stock may decline.

        The level of our common stock dividend is established by our board of directors from time to time based on a variety of factors, including our cash available for distribution, funds from operations and maintenance of our REIT status. Various factors could cause our board of directors to decrease our dividend level, including tenant defaults or bankruptcies resulting in a material reduction in our funds from operations or a material loss resulting from an adverse change in the value of one or more of our properties. If our board of directors determines to reduce our common stock dividend, the market value of our common stock could be adversely affected.

We cannot assure you of our ability to pay dividends in the future.

        We intend to pay quarterly dividends and to make distributions to our stockholders in amounts such that all or substantially all of our taxable income in each year is distributed. This, along with other factors, will enable us to quality for the tax benefits accorded to a REIT under the Internal Revenue Code of 1986, as amended. We have not established a minimum dividend payment level and our ability to pay dividends may be adversely affected by the risk factors described in this Annual Report on Form 10-K. All distributions will be made at the discretion of our board of directors and will depend on our earnings, our financial condition, maintenance of our REIT status and such other factors as our board of directors may deem relevant from time to time. If the economic climate does not continue to improve, our tenants may be further affected, which could likely cause a decline in our revenues, and may reduce or eliminate our profitability and result in the reduction or elimination of our dividends.

Competition in the real estate business is intense and could reduce our revenues and harm our business.

        We compete for real estate investments with all types of investors, including domestic and foreign corporations and real estate companies, financial institutions, insurance companies, pension funds, investment funds, other REITs and individuals. Many of these competitors have significant advantages over us, including a larger, more diverse group of properties and greater financial and other resources.

Compliance with environmental regulations and associated costs could adversely affect our results of operations and liquidity.

        Under various federal, state and local laws, ordinances and regulations, an owner or operator of real property may be required to investigate and clean up hazardous or toxic substances or petroleum product releases at the property and may be held liable to a governmental entity or to third parties for property damage and for investigation and cleanup costs incurred in connection with contamination. The cost of investigation, remediation or removal of hazardous or toxic substances may be substantial, and the presence of such substances, or the failure to properly remediate a property, may adversely affect our ability to sell or rent the property or to borrow money using the property as collateral. In connection with our ownership, operation and management of real properties, we may be considered an owner or operator of the properties and, therefore, potentially liable for removal or remediation costs, as well as certain other related costs, including governmental fines and liability for injuries to persons and property, not only with respect to properties we own now or may acquire, but also with respect to properties we have owned in the past.

15

Table of Contents

        We cannot provide any assurance that existing environmental studies with respect to any of our properties reveal all potential environmental liabilities, that any prior owner of a property did not create any material environmental condition not known to us, or that a material environmental condition does not otherwise exist, or may not exist in the future, as to any one or more of our properties. If a material environmental condition does in fact exist, or exists in the future, the remediation of costs could have a material adverse impact upon our results of operations, liquidity and financial condition.

Compliance with the Americans with Disabilities Act could be costly.

        Under the Americans with Disabilities Act of 1990, all public accommodations must meet Federal requirements for access and use by disabled persons. A determination that our properties do not comply with the Americans with Disabilities Act could result in liability for both governmental fines and damages. If we are required to make unanticipated major modifications to any of our properties to comply with the Americans with Disabilities Act, which are determined not to be the responsibility of our tenants, we could incur unanticipated expenses that could have an adverse impact upon our results of operations, liquidity and financial condition.

Our senior management and other key personnel are critical to our business and our future success depends on our ability to retain them.

        We depend on the services of Fredric H. Gould, chairman of our Board of Directors, Patrick J. Callan, Jr., our president and chief executive officer, Lawrence G. Ricketts, Jr., our executive vice president and chief operating officer, and other members of our senior management to carry out our business and investment strategies. Only two of our senior officers, Messrs. Callan and Ricketts, devote all of their business time to our company. The remainder of our senior management provide services to us on a part-time, as-needed basis. The loss of the services of any of our senior management or other key personnel, or our inability to recruit and retain qualified personnel in the future, could impair our ability to carry out our business and investment strategies.

Our transactions with affiliated entities involve conflicts of interest.

        From time to time we have entered into transactions with persons and entities affiliated with us and with certain of our officers and directors. Our policy for transactions with affiliates is to have these transactions approved by our audit committee and by a majority of our board of directors, including a majority of our independent directors. We entered into a compensation and services agreement with Majestic Property Management Corp. effective as of January 1, 2007. Majestic Property Management Corp. is wholly-owned by the chairman of our Board of Directors and it provides compensation to certain of our senior executive officers. Pursuant to the compensation and services agreement, we pay an annual fee to Majestic Property Management Corp. and they assume our obligations under a shared services agreement, and provide us with the services of all affiliated executive, administrative, legal, accounting and clerical personnel that we use on a part time basis, as well as certain property management services, property acquisition, sales and leasing and mortgage brokerage services. In 2010, we paid Majestic a fee of approximately $2,225,000 under the compensation and services agreement. In addition, in accordance with the compensation and services agreement, in 2010 we paid our chairman a fee of $250,000 and made an additional payment to Majestic Property Management Corp. of $175,000 for our share of all direct office expenses, including rent, telephone, postage, computer services, and internet usage. See Note 10 to our consolidated financial statements for information regarding equity awards to individuals performing services on our behalf.

Risks Related to the REIT Industry

Failure to qualify as a REIT would result in material adverse tax consequences and would significantly reduce cash available for distributions.

        We operate so as to qualify as a REIT under the Internal Revenue Code of 1986, as amended. Qualification as a REIT involves the application of technical and complex legal provisions for which there are limited judicial and administrative interpretations. The determination of various factual matters and circumstances not entirely within our control may affect our ability to qualify as a REIT. In addition, no assurance can be given that legislation, new regulations, administrative interpretations or court decisions will not significantly change the tax laws with respect to qualification as a REIT or the federal income tax consequences of such qualification. If we fail to quality as a REIT, we will be subject to federal, certain additional state and local income tax (including any applicable alternative minimum tax) on our taxable income at regular corporate rates and would not be allowed a deduction in computing our taxable income for amounts distributed to stockholders. In addition, unless entitled to relief under certain statutory provisions, we would be disqualified from treatment as a REIT for the four taxable years following the year during which qualification is lost. The additional tax would reduce significantly our net income and the cash available for distributions to stockholders.

We are subject to certain distribution requirements that may result in our having to borrow funds at unfavorable rates.

        To obtain the favorable tax treatment associated with being a REIT, we generally are required, among other things, to distribute to our stockholders at least 90% of our ordinary taxable income (subject to certain adjustments) each year. To the extent that we satisfy these distribution requirements, but distribute less than 100% of our taxable income we will be subject to federal corporate tax on our undistributed taxable income. In addition, we may be subject to a 4% nondeductible excise tax on the amount, if any, by which certain distributions paid by us with respect to any calendar year are less than the sum of 85% of our ordinary income, 95% of our capital gain net income and 100% of our undistributed income from prior years.

        As a result of differences in timing between the receipt of income and the payment of expenses, and the inclusion of such income and the deduction of such expenses in arriving at taxable income, and the effect of nondeductible capital expenditures, the creation of reserves and the timing of required debt service (including amortization) payments, we may need to borrow funds or make distributions in stock, in order to make the distributions necessary to retain the tax benefits associated with qualifying as a REIT, even if we believe that then prevailing market conditions are not generally favorable for such borrowings. Such borrowings could reduce our net income and the cash available for distributions to holders of our common stock.

Compliance with REIT requirements may hinder our ability to maximize profits.

        In order to qualify as a REIT for Federal income tax purposes, we must continually satisfy tests concerning, among other things, our sources of income, the amounts we distribute to our stockholders and the ownership of our stock. We may also be required to make distributions to stockholders at disadvantageous times or when we do not have funds readily available for distribution. Accordingly, compliance with REIT requirements may hinder our ability to operate solely on the basis of maximizing profits.

        In order to qualify as a REIT, we must also ensure that at the end of each calendar quarter, at least 75% of the value of our assets consists of cash, cash items, government securities and qualified REIT real estate assets. Any investment in securities cannot include more than 10% of the outstanding voting securities of any one issuer or more than 10% of the total value of the outstanding securities of any one issuer. In addition, no more than 5% of the value of our assets can consist of the securities of

17

---

Table of Contents

any one issuer, other than a qualified REIT security. If we fail to comply with these requirements, we must dispose of such portion of these securities in excess of these percentages within 30 days after the end of the calendar quarter in order to avoid losing our REIT status and suffering adverse tax consequences. This requirement could cause us to dispose of assets for consideration that is less than their true value and could lead to an adverse impact on our results of operations and financial condition.

        At December 31, 2010, our joint ventures had first mortgages on three properties with outstanding balances aggregating approximately $17.4 million, bearing interest at rates ranging from 5.8% to 6.4%. with a weighted average interest rate of 6.0%. Substantially all of these mortgages contain prepayment penalties. The following table sets forth the scheduled principal mortgage payments due for properties owned by our joint ventures as of December 31, 2010, and assumes no payment is made on principal on any outstanding mortgage in advance of its due date:

Significant Tenants

        As of December 31, 2010, no single property owned by us had a book value equal to or greater than 10% of our total assets or had revenues which accounted for more than 10% of our aggregate annual gross revenues in the year ended December 31, 2010.

Haverty Furniture Companies, Inc.

        As of December 31, 2010, we owned a portfolio of eleven properties leased under a master lease to Haverty Furniture Companies, Inc., which properties had an aggregate net book value equal to 12.5% of the depreciated book value of our real estate investments, and revenues which in 2010 accounted for 11.6% of our rental income. Of the eleven properties, three are located in each of Texas and Virginia, two are located in Georgia, and one is located in each of Kansas, Kentucky and South Carolina. The properties contain buildings with an aggregate of approximately 612,130 square feet.

25

Table of Contents

        The properties are net leased to Haverty Furniture Companies, Inc. pursuant to a master lease, which expires on August 14, 2022. Haverty Furniture Companies, Inc. is a New York Stock Exchange listed company. The master lease provides for a current base rent of $4,310,000 per annum (which accounts for 10.4% of our 2011 contractual rental income), increasing by 6% on August 15, 2012 and 2017, and provides the tenant with certain renewal options. Pursuant to the master lease, the tenant is responsible for maintenance and repairs, and for real estate taxes and assessments on the properties. The 2010 annual real estate taxes on the properties aggregated $788,000.

        The mortgage loan, assumed by our subsidiary when it acquired these eleven properties in 2006, is secured by mortgages/deeds of trust on all such properties in the principal amount of approximately $24.1 million at December 31, 2010. The mortgage loan bears interest at 6.87% per annum, matures on September 1, 2012 and is being amortized based on a 25-year amortization schedule. Assuming only contractual payments are made on the principal amount of the mortgage loan, the principal balance due on the maturity date will be approximately $23 million. Although the mortgage loan provides for defeasance, it is generally not prepayable until 90 days prior to the maturity date.

Office Depot, Inc.

        As of December 31, 2010, we owned a portfolio of ten properties, each of which is subject to a lease with Office Depot, Inc. These properties have an aggregate net book value equal to 11.8% of the depreciated book value of our real estate investments, accounted for 10.6% of our 2010 rental income and accounts for 10.7% of our 2011 contractual rental income. Two properties are located in each of Florida and Georgia, and one is located in each of California, Illinois, Louisiana, North Carolina, Oregon and Texas. The properties contain buildings with an aggregate of approximately 261,678 square feet.

        Each property is subject to a separate lease. Eight of the leases contain cross-default provisions, expire on September 30, 2018, and provide the tenant with four five-year renewal options. One lease expires on June 30, 2013 and provides the tenant with three five-year renewal options, and one lease expires on February 28, 2014 and provides the tenant with four five-year renewal options. Office Depot, Inc. is a New York Stock Exchange listed company. The ten leases provide for an aggregate current base rent of $4,439,000. The rent for eight of the properties increases every five years by 10%. The rent for one property increases by 5% every five years and the rent for one property increases by $20,000 every five years. Pursuant to the leases, the tenant is responsible for maintenance and repairs, and for real estate taxes and assessments on the properties. The 2010 annual real estate taxes on the properties aggregated $707,000.
