On August 26, 2013, we entered into a term loan we call the BMO Term Loan and borrowed $220 million. Additional information about these loans are in the footnotes to our financial statements. Pricing is based on our credit rating for the BAML Revolver, BAML Term Loan and the BMO Term Loan. Our credit rating as of September 30, 2015 was Baa3 from Moody’s. The BAML Revolver is priced based on our current credit rating at a spread of 1.25%, which was an interest rate of 1.44% as of September 30, 2015. The BAML Revolver is also subject to a facility fee based on our credit rating, which was 25 bps or approximately $1.25 million per year. The BAML Term Loan has LIBOR fixed at 0.75% for five years. At our credit rating, the spread for the BAML Term Loan is 1.45%, so our interest rate is 2.20%. The BMO Term Loan has fixed LIBOR at 2.32% for seven years. At our credit rating, the spread over LIBOR is 1.65%, so our interest rate is 3.97%. We incurred financing costs to close the BAML Revolver, BAML Term Loan and the credit facilities that preceded them. We also incurred financing costs to close the BMO Term Loan. These costs are deferred and amortized into interest expense during the terms of the loans. The annual run rate for amortization to interest expense from deferred financing costs is approximately $2.1 million. The BAML Revolver can be extended for 1 year at the Company’s option upon payment of fees and includes an accordion feature that allows for up to $250 million of additional borrowing capacity. The BMO Term Loan includes an accordion feature that allows for up to $50 million of additional borrowing capacity. The accordion features are subject to receipt of lender commitments and satisfaction of certain customary conditions. September 30, 2015 12

Appendix: Non-GAAP Financial Measure Definitions Definition of Funds From Operations (“FFO”) The Company evaluates performance based on Funds From Operations, which we refer to as FFO, as management believes that FFO represents the most accurate measure of activity and is the basis for distributions paid to equity holders. The Company defines FFO as net income (computed in accordance with GAAP), excluding gains (or losses) from sales of property and acquisition costs of newly acquired properties that are not capitalized, plus depreciation and amortization, including amortization of acquired above and below market lease intangibles and impairment charges on properties or investments in non-consolidated REITs, and after adjustments to exclude equity in income or losses from, and, to include the proportionate share of FFO from, non-consolidated REITs. FFO should not be considered as an alternative to net income (determined in accordance with GAAP), nor as an indicator of the Company’s financial performance, nor as an alternative to cash flows from operating activities (determined in accordance with GAAP), nor as a measure of the Company’s liquidity, nor is it necessarily indicative of sufficient cash flow to fund all of the Company’s needs. Other real estate companies and the National Association of Real Estate Investment Trusts, or NAREIT, may define this term in a different manner. We have included the NAREIT FFO definition in our table and note that other REITs may not define FFO in accordance with the current NAREIT definition or may interpret the current NAREIT definition differently than we do. We believe that in order to facilitate a clear understanding of the results of the Company, FFO should be examined in connection with net income and cash flows from operating, investing and financing activities in the consolidated financial statements. September 30, 2015 27

Appendix: Non-GAAP Financial Measure Definitions Definition of Earnings before Interest, Taxes, Depreciation and Amortization (EBITDA) and Adjusted EBITDA EBITDA is defined as net income plus interest expense, income tax expense and depreciation and amortization expense. Adjusted EBITDA is defined as EBITDA excluding gains and losses on sales of properties or shares of equity investments or provisions for losses on assets held for sale. EBITDA and Adjusted EBITDA are not intended to represent cash flow for the period, are not presented as an alternative to operating income as an indicator of operating performance, should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP and are not indicative of operating income or cash provided by operating activities as determined under GAAP. EBITDA and Adjusted EBITDA are presented solely as a supplemental disclosure with respect to liquidity because the Company believes it provides useful information regarding the Company's ability to service or incur debt. Because all companies do not calculate EBITDA or Adjusted EBITDA the same way, this presentation may not be comparable to similarly titled measures of other companies. The Company believes that net income is the financial measure calculated and presented in accordance with GAAP that is most directly comparable to EBITDA and Adjusted EBITDA. Definition of Property Net Operating Income (Property NOI) The Company provides property performance based on Net Operating Income, which we refer to as NOI. Management believes that investors are interested in this information. NOI is a non-GAAP financial measure that the Company defines as net income (the most directly comparable GAAP financial measure) plus selling, general and administrative expenses, depreciation and amortization, including amortization of acquired above and below market lease intangibles and impairment charges, interest expense, less equity in earnings of nonconsolidated REITs, interest income, management fee income, gains or losses on the sale of assets and excludes non-property specific income and expenses. The information presented includes footnotes and the data is shown by region with properties owned in both periods, which we call Same Store. The Comparative Same Store results include properties held for the periods presented and exclude significant nonrecurring income such as bankruptcy settlements and lease termination fees. NOI, as defined by the Company, may not be comparable to NOI reported by other REITs that define NOI differently. NOI should not be considered an alternative to net income as an indication of our performance or to cash flows as a measure of the Company's liquidity or its ability to make distributions. September 30, 2015 28

Appendix: Non-GAAP Financial Measure Definitions Definition of Adjusted Funds From Operations (AFFO) The Company defines AFFO as the sum of (1) FFO; (2) excluding our proportionate share of FFO and including distributions received, from non-consolidated REITs; (3) excluding the effect of straight-line rent; (4) plus deferred financing costs, (5) less recurring capital expenditures that are generally for (a) maintenance of properties, which we call non-investment capex or are second generation capital expenditures. Second generation costs include re-tenanting space after a tenant vacates, which include tenant improvements and leasing commissions. We exclude development/redevelopment activities, capital expenditures planned at acquisition and costs to reposition a property. We also exclude first generation leasing costs, which are generally to fill vacant space in properties we acquire or were planned for at acquisition. AFFO should not be considered as an alternative to net income (determined in accordance with GAAP), as an indicator of the Company’s financial performance, nor as an alternative to cash flows from operating activities (determined in accordance with GAAP), nor as a measure of the Company’s liquidity, nor is it necessarily indicative of sufficient cash flow to fund all of the Company’s needs. Other real estate companies may define this term in a different manner. We believe that in order to facilitate a clear understanding of the results of the Company, AFFO should be examined in connection with net income and cash flows from operating, investing and financing activities in the consolidated financial statements.
