Washington Real Estate Investment Trust (“WRIT”) is a self-administered, self-managed, equity real estate investment trust investing in income-producing properties in the greater Washington metro region. WRIT is diversified, as it invests in office, industrial/flex, medical office, retail, and multifamily properties and land for development.

Since WRIT reported second quarter results, the company issued 1,576,940 shares at an average price of $31.13 per share through its Sales Agency Financing Agreement with BNY Mellon Capital Markets, generating approximately $49 million in proceeds. These proceeds were used to pay down a portion of the line of credit and for general corporate purposes. At the end of the third quarter, the outstanding balance on the line of credit was $100 million. Year to date, WRIT has issued 3,965,269 common shares through the Agreement with BNY Mellon for gross proceeds of approximately $120 million.

In the third quarter WRIT repurchased $7.6 million of its 3.875% convertible notes at an average price of 100.25% of par, and also prepaid without penalty a $21.7 million 5.82% mortgage note on The Ridges and The Crescent office properties in Gaithersburg, Maryland on July 12, 2010.

Also in the third quarter WRIT completed an underwritten public offering of $250 million aggregate principal amount of senior unsecured notes due October 1, 2020 under its shelf registration statement filed with the Securities and Exchange Commission. The notes have an annual coupon rate of 4.95% and were priced at 99.199% of the principal amount. Pursuant to a tender offer, WRIT used a portion of the proceeds to purchase $56.1 million aggregate principal amount of its outstanding 5.95% senior notes due June 15, 2011 and $122.8 million aggregate principal amount of its outstanding 3 7/8% convertible senior notes due 2026. The remainder of the proceeds will be used for general corporate purposes.

During the third quarter, WRIT signed commercial leases for 330,000 square feet with an average lease term of 4.4 years. The average rental rate increase on new and renewal leases was 6.8% on a GAAP basis and -2.4% on a cash basis. Commercial tenant improvement costs were $6.91 per square foot and leasing costs were $4.51 per square foot for the quarter.

As of September 30, 2010, WRIT owned a diversified portfolio of 88 properties totaling approximately 11 million square feet of commercial space and 2,540 residential units. These 88 properties consist of 26 office properties, 19 industrial/flex properties, 18 medical office properties, 14 retail centers, 11 multifamily properties and land for development. WRIT shares are publicly traded on the New York Stock Exchange (NYSE:WRE).

(1)Funds From Operations (“FFO”) – The National Association of Real Estate Investment Trusts, Inc. (“NAREIT”) defines FFO (April, 2002 White Paper) as net income (computed in accordance with generally accepted accounting principles (“GAAP”)) excluding gains (or losses) from sales of property plus real estate depreciation and amortization. We consider FFO to be a standard supplemental measure for equity real estate investment trusts (“REITs”) because it facilitates an understanding of the operating performance of our properties without giving effect to real estate depreciation and amortization, which historically assumes that the value of real estate assets diminishes predictably over time. Since real estate values have instead historically risen or fallen with market conditions, we believe that FFO more accurately provides investors an indication of our ability to incur and service debt, make capital expenditures and fund other needs. FFO is a non-GAAP measure. (2)Funds Available for Distribution (“FAD”) is calculated by subtracting from FFO (1) recurring expenditures, tenant improvements and leasing costs, that are capitalized and amortized and are necessary to maintain our properties and revenue stream and (2) straight line rents, then adding (3) non-real estate depreciation and amortization and adding or subtracting the amortization of lease intangibles as appropriate. FAD is included herein, because we consider it to be a measure of a REIT’s ability to incur and service debt and to distribute dividends to its shareholders. FAD is a non-GAAP and non-standardized measure, and may be calculated differently by other REITs.

Adjusted EBITDA	$	48,514		$	48,008		$	46,203	$	49,327		$	46,680

⁽¹⁾ Adjusted EBITDA is earnings before interest expense, taxes, depreciation, amortization, gain on sale of real estate, gain/loss on extinguishment of debt and gain from non-disposal activities. We consider Adjusted EBITDA to be an appropriate supplemental performance measure because it permits investors to view income from operations without the effect of depreciation, the cost of debt or non-operating gains and losses. Adjusted EBITDA is a non-GAAP measure.

⁽¹⁾ On December 1, 2009, we borrowed $100.0 million on a line of credit in order to prepay the $100.0 million term loan. Through February 19, 2010, the interest rate on this $100.0 million borrowing on our lines of credit is effectively fixed by an interest rate swap at 3.375%. Beginning February 20, 2010 through November 1, 2011, an interest rate swap effectively fixes the interest rate at 2.525%.

Weighted average maturity = 4.9 years

⁽¹⁾ The 3.875% convertible notes due 2026 in the aggregate principal amount of $125.5 million are puttable at par in September, 2011. Due to the probability that the convertible notes will be paid off in September, 2011, that date is reflected in the future maturities schedule. The effective rate on this debt is 5.875%, which reflects the our nonconvertible debt borrowing rate at the inception of the 3.875% convertible notes.

⁽²⁾ Subsequent to the end of the quarter, we used a portion of the proceeds from our 4.95% senior notes due in 2020 to purchase $56.1 million of our outstanding 5.95% senior notes due in 2011 and $122.8 million of our 3.875% convertible notes that are puttable at par in 2011.

⁽¹⁾ Total Assets is calculated by applying a capitalization rate of 7.50% to the EBITDA⁽³⁾ from the last four consecutive quarters, excluding EBITDA from acquired, disposed, and non-stabilized development properties.

⁽²⁾ Total Unencumbered Assets is calculated by applying a capitalization rate of 7.50% to the EBITDA⁽³⁾ from unencumbered properties from the last four consecutive quarters, excluding EBITDA from acquired, disposed, and non-stabilized development properties.

⁽³⁾ EBITDA is defined in our debt covenants as earnings before interest income, interest expense, taxes, depreciation, amortization, gain on sale of real estate, gain/loss on extinguishment of debt and gain from non-disposal activities.

⁽⁴⁾ Gross Asset Value is calculated by applying a capitalization rate to the annualized EBITDA⁽³⁾ from the most recently ended quarter, excluding EBITDA from disposed properties and current quarter acquisitions. To this amount, the purchase price of current quarter acquisitions, cash and cash equivalents and development in progress is added.

⁽⁵⁾ Fixed Charges consist of interest expense, principal payments, ground lease payments and replacement reserve payments.

⁽⁶⁾ Non-Wholly Owned Assets is calculated by applying a capitalization rate of 7.50% to the EBITDA⁽³⁾ from properties subject to a joint operating agreement (i.e. NVIP I&II). We add to this amount the development in progress subject to a joint operating agreement (i.e. 4661 Kenmore Avenue).

⁽⁷⁾ Unencumbered Pool Value is calculated by applying a capitalization rate of 7.75% to the net operating income from unencumbered properties owned for the entire quarter. To this we add the purchase price of unencumbered acquisitions during the current quarter and development in progress.

⁽¹⁾ The ratio of earnings to fixed charges is computed by dividing earnings by fixed charges. For this purpose, earnings consist of income from continuing operations attributable to the controlling interests plus fixed charges, less capitalized interest. Fixed charges consist of interest expense, including amortized costs of debt issuance, plus interest costs capitalized.

⁽²⁾ Debt service coverage ratio is computed by dividing Adjusted EBITDA (see page 7) by interest expense and principal amortization.

Annualized base rent (ABR) is calculated as monthly base rent (cash basis) per the lease, as of the reporting period, multiplied by 12.

Debt to total market capitalization is total debt from the balance sheet divided by the sum of total debt from the balance sheet plus the market value of shares outstanding at the end of the period.

Adjusted EBITDA (a non-GAAP measure) is earnings attributable to the controlling interest before interest expense, taxes, depreciation, amortization, gain on sale of real estate, gain/loss on extinguishment of debt and gain/loss from non-disposal activities.

Ratio of earnings to fixed charges is computed by dividing earnings attributable to the controlling interest by fixed charges. For this purpose, earnings consist of income from continuing operations (or net income if there are no discontinued operations) plus fixed charges, less capitalized interest. Fixed charges consist of interest expense, including amortized costs of debt issuance, plus interest costs capitalized.

Debt service coverage ratio is computed by dividing earnings attributable to the controlling interest before interest expense, taxes, depreciation, amortization, gain on sale of real estate, gain/loss on extinguishment of debt and gain/loss from non-disposal activities by interest expense and principal amortization.

Funds from operations (FFO) - The National Association of Real Estate Investment Trusts, Inc. (NAREIT) defines FFO (April, 2002 White Paper) as net income attributable to the controlling interest (computed in accordance with generally accepted accounting principles (GAAP)) excluding gains (or losses) from sales of property plus real estate depreciation and amortization. FFO is a non-GAAP measure.

Funds Available for Distribution (FAD), a non-GAAP measure, is calculated by subtracting from FFO recurring expenditures, tenant improvements, leasing incentives and leasing costs, that are capitalized and amortized and are necessary to maintain our properties and revenue stream, non-cash gain/loss from extinguishment of debt and straight line rents, then adding non-real estate depreciation and amortization, non-cash fair value interest expense, adding or subtracting amortization of lease intangibles and amortization of restricted share compensation, as appropriate.

Recurring capital expenditures represents non-accretive building improvements and leasing costs required to maintain current revenues. Recurring capital expenditures do not include acquisition capital that was taken into consideration when underwriting the purchase of a building or which are incurred to bring a building up to “operating standard.”

Rent increases on renewals and rollovers are calculated as the difference, weighted by square feet, of the net ABR due the first month after a term commencement date and the net ABR due the last month prior to the termination date of the former tenant’s term.

Core portfolio properties include all properties that were owned for the entirety of the current and prior year reporting periods.
