Corporate Data

Piedmont Office Realty Trust, Inc. (“Piedmont” or the “Company”) (NYSE: PDM) is a fully-integrated and self-managed real estate investment trust (“REIT”) specializing in the acquisition, ownership, management, development and disposition of primarily high-quality Class A office buildings located predominantly in large U.S. office markets and leased principally to high-credit-quality tenants. Approximately 82% of our Annualized Lease Revenue (“ALR”)⁽¹⁾ is derived from our office properties located within the ten largest U.S. office markets, including Chicago, Washington, D.C., the New York metropolitan area, Boston and greater Los Angeles. Since its first acquisition in 1998, the Company has acquired $5.9 billion of office and industrial properties (inclusive of joint ventures) through March 31, 2012. Rated as an investment-grade company by Standard & Poor’s and Moody’s, Piedmont has maintained a low-leverage strategy while acquiring its properties.

This data supplements the information provided in our reports filed with the Securities and Exchange Commission and should be reviewed in conjunction with such filings.

Financial Highlights

As of March 31, 2012

Financial Results⁽¹⁾                    

- Funds from operations (FFO) for the quarter ended March 31, 2012 was $60.0 million, or $0.35 per share (diluted), compared to $71.3 million, or $0.41 per share (diluted), for the same quarter in 2011. The decrease in FFO for the three months ended March 31, 2012 as compared to the same period in 2011 was principally related to three factors: 1) decreased operating income due to the disposition of certain assets with meaningful operating income contributions, notably 35 West Wacker Drive, and lower overall leased percentage in 2012 as compared to 2011, offset somewhat by operating income contributions from newly acquired assets, 2) reduced termination fee income of $3.3 million in 2012 as compared to 2011, and 3) the one-time recognition in 2011 of $2.6 million of deferred operating income from the 500 West Monroe Street property related to the conversion of our mezzanine loan investment collateralized by equity ownership of the building to an owned property through foreclosure. The items contributing to the reduction in FFO in 2012 as compared to 2011 are offset somewhat by $1.4 million of reduced General & Administrative expenses related primarily to increased legal expense reimbursements in 2012 as compared to 2011.

- Core funds from operations (Core FFO) for the quarter ended March 31, 2012 was $60.0 million, or $0.35 per share (diluted), compared to $71.3 million, or $0.41 per share (diluted), for the same quarter in 2011. The decrease in Core FFO for the three months ended March 31, 2012 as compared to the same period in 2011 was principally related to the items described for changes in FFO above.

- Adjusted funds from operations (AFFO) for the quarter ended March 31, 2012 was $50.1 million, or $0.29 per share (diluted), compared to $56.3 million, or $0.33 per share (diluted), for the same quarter in 2011. The decrease in AFFO for the three months ended March 31, 2012 as compared to the same period in 2011 was primarily related to the items described above for the FFO variance, offset somewhat by a decrease in non-incremental capital expenditures in 2012 as compared to 2011.

- During the quarter ended March 31, 2012, the Company paid to shareholders a quarterly dividend in the amount of $0.20 per share for its common stock. The Company’s dividend payout percentage for the three months ended March 31, 2012 was 58% of Core FFO and 69% of AFFO. The dividend was reduced from an annualized $1.26 per share to $0.80 per share, an approximate $80 million reduction per annum.

Operations                                     

- On a square footage leased basis, our total office portfolio was 84.4% leased as of March 31, 2012, as compared to 86.5% as of December 31, 2011. On a stabilized square footage leased basis, our portfolio was 87.5% leased as of March 31, 2012, as compared to 89.1% leased as of December 31, 2011. The stabilized leased percentage excludes the impact of value-add acquisitions (see page 33) that have not yet reached stabilization, including 500 West Monroe Street in Chicago, IL, 1200 Enclave Parkway in Houston, TX, The Medici in Atlanta, GA, Suwanee Gateway One in Suwanee, GA, and 400 TownPark in Lake Mary, FL. The primary reason for the decline in the leased rate for our stabilized assets between December 31, 2011 and March 31, 2012 is the net reduction of 221,000 leased square feet associated with the Sanofi-aventis US lease expiration at 200 Bridgewater Crossing in Bridgewater, NJ and the net reduction of approximately 121,000 leased square feet associated with the Marsh USA lease expiration at 500 West Monroe Street in Chicago, IL. Please refer to page 22 for additional information.

- The weighted average remaining lease term of our portfolio was 6.6 years⁽²⁾ as of March 31, 2012 as compared to 6.4 years at December 31, 2011.

- During the three months ended March 31, 2012, the Company completed 810,000 square feet of leasing at our properties, inclusive of our industrial and joint venture assets. Of the total leasing activity during the quarter, we signed renewal leases for 348,000 square feet and new tenant leases for 462,000 square feet. Leases for approximately 437,000 square feet were signed for our wholly-owned office properties with an average committed capital cost of $3.15 per square foot per year of lease term. Average committed capital cost per square foot per year of lease term for renewal leases signed during the quarter ended March 31, 2012 was $0.53 and average committed capital cost per square foot per year of lease term for new leases signed during the same time period was $4.98.

⁽¹⁾FFO, Core FFO and AFFO are supplemental non-GAAP financial measures. See pages 35-36 for definitions of non-GAAP financial measures. See pages 13 and 38 for reconciliations of FFO, Core FFO and AFFO to Net Income.

⁽²⁾ Remaining lease term (after taking into account leases for vacant spaces which had been executed but not commenced as of March 31, 2012) is weighted based on Annualized Lease Revenue, as defined on page 35.

Financing and Capital Activity            

- As of March 31, 2012, our ratio of debt to total gross assets was 25.7%, our ratio of debt to gross real estate assets was 29.5%, and our ratio of debt to total market capitalization was 30.6%. These debt ratios are based on total principal amount outstanding for our various loans at March 31, 2012. Subsequent to quarter end, we repaid the $45 million loan secured by 4250 North Fairfax Drive in Arlington, VA. Our pro forma leverage ratios, after adjusting for the repayment of that debt and assuming that $25 million of repayment proceeds was from cash, are: 25.4% for debt to total gross assets, 28.9% for debt to gross real estate assets, and 30.2% for debt to total market capitalization.

- On March 19, 2012, Piedmont completed the sale of its properties in Beaverton, OR, allowing the Company to exit the Portland, OR market and further its strategic objective of focusing on select markets. The properties, which were sold for $43.9 million, were comprised of approximately 326,000 square feet of office space and 18.2 acres of developable land. The operating income for the assets is presented in discontinued operations. Piedmont recorded a gain on the sale of properties of $17.8 million. As part of the sale transaction, Piedmont provided $19 million in seller financing to the buyer, NIKE, Inc. The interest-only loan to NIKE bears interest at 8.73% and has a maturity date of October 31, 2012.

- On January 9, 2012, Piedmont repaid a $140 million loan secured by 500 West Monroe Street in Chicago, IL. The loan was open to prepayment without any yield maintenance requirements. The repayment of the loan allowed Piedmont to further its strategic objective of decreasing its secured debt borrowings in relation to its total borrowings.

- On February 28, 2012, the Board of Directors of Piedmont declared dividends for the first quarter of 2012 in the amount of $0.20 per common share outstanding to stockholders of record as of the close of business on March 9, 2012. The dividends were paid on March 22, 2012.

Financial Highlights

As of March 31, 2012

- During the first quarter of 2012, no additional purchases were made under the company’s stock repurchase program. Since the program’s inception last fall, the Company has repurchased a total of 199,400 shares at an average price of $16.24 per share. Any future repurchases of the Company’s common stock will be made at the discretion of the Company.

- The trial date for the ongoing shareholder litigation has been postponed. Piedmont believes that the case is without merit and intends to continue to vigorously defend the complaint. See Piedmont’s Form 10-Q dated as of March 31, 2012 for further disclosure.

Subsequent Events                              

- On May 1, 2012, Piedmont repaid a $45 million loan secured by 4250 North Fairfax Drive in Arlington, VA. The loan was open to prepayment without any yield maintenance requirements. The repayment of the loan allowed Piedmont to further its strategic objective of decreasing its secured debt borrowings in relation to its total borrowings. Please see Financing and Capital Activity above for pro forma leverage ratios, which take into account the repayment of this debt.

- On May 2, 2012, the Board of Directors of Piedmont declared dividends for the second quarter of 2012 in the amount of $0.20 per common share outstanding to stockholders of record as of the close of business on June 1, 2012. The dividends are to be paid on June 22, 2012.

Guidance for 2012                               

- The following financial guidance for calendar year 2012 remains unchanged and is based on management’s expectations at this time:

	Low        High
Core Funds from Operations	$234   -  $250 million
Core Funds from Operations per diluted share	$1.35  -  $1.45

These estimates reflect management’s view of current market conditions and incorporate certain economic and operational assumptions and projections, including the disposition of 35 West Wacker Drive which contributed approximately $0.13 per share of funds from operations in 2011. Actual results could differ from these estimates. Note that individual quarters may fluctuate on both a cash and an accrual basis due to the timing of lease commencements and expirations, repairs and maintenance, capital expenditures, capital markets activities and one-time revenue or expense events. In addition, the Company’s guidance is based on information available to management as of the date of this supplemental report.

⁽¹⁾ Please refer to page 22 for additional leased percentage information.

⁽²⁾ Please refer to page 33 for additional information on value-add properties, data for which is removed from stabilized portfolio totals.

⁽³⁾Net debt is calculated as the total principal amount of debt outstanding minus cash and cash equivalents and escrow deposits and restricted cash. As of the first quarter of 2011, net debt includes $185 million of secured debt associated with 500 West Monroe Street which was acquired March 31, 2011; $45 million of that debt was repaid during the fourth quarter of 2011 and the remaining $140 million was repaid during the first quarter of 2012. Each quarter prior to the fourth quarter of 2011 includes $120 million of debt associated with 35 West Wacker Drive, an asset sold in December 2011.

⁽⁴⁾Core EBITDA margin is calculated as Core EBITDA divided by total revenues (including revenues associated with discontinued operations).

⁽⁵⁾ The fixed charge coverage ratio is calculated as Core EBITDA divided by the sum of interest expense, principal amortization, capitalized interest and preferred dividends. The Company had no capitalized interest, principal amortization or preferred dividends during any of the periods presented.

⁽⁶⁾ The change in Piedmont’s debt coverage ratios during 2011 was primarily attributable to $185 million of additional debt assumed with the acquisition of 500 West Monroe Street in March 2011 and the related interest expense; $45 million of this debt was repaid on November 17, 2011, and the remaining $140 million was repaid on January 9, 2012.

⁽⁷⁾Core EBITDA is annualized for the purposes of this calculation.

⁽²⁾Acquisitions consist of 1200 Enclave Parkway in Houston, TX, purchased on March 30, 2011; 500 West Monroe Street in Chicago, IL, acquired on March 31, 2011; The Dupree in Atlanta, GA, purchased on April 29, 2011; The Medici in Atlanta, GA, purchased on June 7, 2011; 225 and 235 Presidential Way in Woburn, MA, purchased on September 13, 2011; and 400 TownPark in Lake Mary, FL purchased on November 10, 2011.

⁽³⁾Dispositions consist of Eastpointe Corporate Center in Issaquah, WA, sold on July 1, 2011; 5000 Corporate Court in Holtsville, NY, sold on August 31, 2011; 35 West Wacker Drive in Chicago, IL, sold on December 15, 2011; and Deschutes, Rhein, Rogue, and Willamette in Beaverton, OR, sold on March 19, 2012.

⁽⁴⁾ The increase in Washington, D.C. Same Store Net Operating Income for the three months ended March 31, 2012 as compared to the same period in 2011 was primarily related to increased rental revenue principally attributable to the commencement of the NASA swing space lease at 1201 Eye Street in Washington, D.C. as well as an increase in revenue due to a rental rate increase associated with the lease extension of the Comptroller of the Currency at One Independence Square in Washington, D.C.

⁽⁵⁾ The decrease in the New York Same Store Net Operating Income for the three months ended March 31, 2012 as compared to the same period in 2011 was primarily related to partial lease terminations with Sanofi-aventis at 200 & 400 Bridgewater Crossing in Bridgewater, NJ in order to allow for the execution of new long-term leases to backfill the terminated spaces in advance of the March 2012 Sanofi-aventis lease expirations.

⁽⁶⁾ The decrease in Chicago Same Store Net Operating Income for the three months ended March 31, 2012 as compared to the same period in 2011 was primarily related to the expiration of the Zurich American Insurance Company lease at Windy Point II in Schaumburg, IL as well as the expiration of the Kirkland & Ellis lease at Aon Center in Chicago, IL. The loss of the Zurich lease contributed approximately $2.7 million to the quarter's variance and the loss of the Kirkland & Ellis lease contributed approximately $2.5 million to the quarter's variance. These negative contributors are offset somewhat by the commencement of several new leases during the last year.

⁽⁷⁾ The decrease in Boston Same Store Net Operating Income for the three months ended March 31, 2012 as compared to the same period in 2011 was primarily due to a rental abatement concession associated with a long-term lease renewal with State Street Bank at 1200 Crown Colony Drive in Quincy, MA. The renewal period for the State Street Bank lease commenced in April 2011.

⁽⁸⁾ The decrease in Other Same Store Net Operating Income for the three months ended March 31, 2012 as compared to the same period in 2011 was primarily attributable to two factors: 1) a rental abatement concession in 2012 associated with a new lease with Chrysler Group, LLC at 1075 West Entrance Drive in Auburn Hills, MI, and 2) a rental abatement concession in 2012 associated with a new lease with Grand Canyon Education at Desert Canyon 300 in Phoenix, AZ.

The loss of the Zurich lease contributed approximately $2.5 million to the quarter’s variance and the loss of the Kirkland & Ellis lease contributed approximately $2.5 million to the quarter’s variance. These negative contributors are offset somewhat by the commencement of several new leases during the last year.

⁽⁷⁾ The decrease in Minneapolis Same Store Net Operating Income for the three months ended March 31, 2012 as compared to the same period in 2011 was primarily related to the net loss of approximately 80,000 leased square feet associated with the expiration of the HSBC Card Services lease at Crescent Ridge II in Minnetonka, MN as well as an 80,000 square foot partial lease termination by US Bank (of which approximately 40,000 square feet has yet to be re-leased) during the second quarter of 2011 at US Bancorp Center in Minneapolis, MN.

⁽⁸⁾ The decrease in Boston Same Store Net Operating Income for the three months ended March 31, 2012 as compared to the same period in 2011 was primarily due to a rental rate reduction associated with a long-term lease renewal with State Street Bank at 1200 Crown Colony Drive in Quincy, MA. The renewal period for the State Street Bank lease commenced in April 2011.

This definition of fixed charge coverage ratio as prescribed by our line of credit agreement is different from the fixed charge coverage ratio definition employed elsewhere within this report. (3) Defined as net operating income for the trailing four quarters for unencumbered assets (including the company's share of net operating income from unconsolidated interests that are unencumbered) less a $0.15 per square foot capital reserve divided by the company's share of interest expense associated with unsecured financings only, as more particularly described in the credit agreements. (4) Permitted investments are defined as unconsolidated interests, debt investments, unimproved land, and development projects. Investments in permitted investments shall not exceed 35% of total asset value.

Leased Percentage Information

(in thousands)

Impact of Strategic Transactions on Leased Percentage

The Company’s stated long-term growth strategy includes the recycling of capital from certain stabilized or non-core assets into office properties located in focused concentration and opportunistic markets. Some of the recently acquired properties are value-add properties which are defined as low-occupancy properties acquired at attractive bases with earnings growth and capital appreciation potential achievable through leasing up such assets to a stabilized occupancy. Because the value-add properties have large vacancies, they negatively affect Piedmont’s overall leased percentage. In order to identify the effect they have on Piedmont’s overall leased percentage, the following information is being provided. The analysis below: 1) removes the impact of the value-add properties from Piedmont’s overall office portfolio total under the heading “Stabilized Portfolio Analysis”; and 2) provides a year-over-year comparison of leased percentage on the same subset of properties under the heading “Same Store Analysis”.

⁽¹⁾ Calculated as leased square footage as of period end with the addition of square footage associated with uncommenced leases for spaces vacant as of period end, divided by total rentable square footage as of period end, expressed as a percentage.

⁽²⁾ The square footage associated with leases with end of period expiration dates is included in the end of the period leased square footage.

⁽³⁾ End of period leased square footage for 2012 includes short-term space leased on behalf of NASA in accordance with requirements stipulated under its lease to allow it to restructure its space at Two Independence Square in Washington, D.C. As of March 31, 2012, the total short-term space amounts to approximately 63,000 square feet and it will be occupied until an estimated date of September 30, 2013.

⁽⁴⁾ Dispositions completed during the previous twelve months are deducted from the previous period data and acquisitions completed during the previous twelve months are deducted from the current period data.

⁽⁵⁾ For additional information on acquisitions/dispositions completed during the last year and value-add properties, please refer to pages 32 and 33, respectively.

⁽⁶⁾ Excluding executed but not commenced leases for currently vacant spaces, comprising approximately 684,000 square feet for the current period and 379,000 square feet for the prior period, Piedmont's same store commenced leased percentage was 81.5% and 84.9%, respectively.

Leases executed for spaces excluded from analysis(5)		82		19	%

⁽¹⁾ The population analyzed consists of office leases executed during the period (retail leases, as well as leases associated with storage spaces, management offices, industrial properties and unconsolidated joint venture assets, were excluded from this analysis). Spaces that had been vacant for greater than one year were excluded from this analysis.

⁽²⁾ For the purposes of this analysis, the cash rents last in effect for the previous leases were compared to the initial cash rents of the new leases in order to calculate the percentage change.

⁽³⁾ For the purposes of this analysis, the accrual basis rents for the previous leases were compared to the accrual basis rents of the new leases in order to calculate the percentage change. For newly signed leases which have variations in accrual basis rents, whether because of known future expansions, contractions, lease expense recovery structure changes, or other similar reasons, the weighted average of such accrual basis rents is used for the purposes of this analysis.

⁽⁴⁾ For leases under which a tenant may use, at its discretion, a portion of its tenant improvement allowance for expenses other than those related to improvements to its space, an assumption is made that the tenant elects to use any such portion of its tenant improvement allowance for improvements to its space prior to the commencement of its lease, unless the Company is notified otherwise by the tenant. This assumption is made based upon the historical tenant improvement allowance usage patterns of the Company’s tenants.

⁽⁵⁾ Represents leases signed at our consolidated office assets that do not qualify for inclusion in the analysis primarily because the spaces for which the new leases were signed had been vacant for greater than one year. Leases signed with Piedmont entities are excluded from the analysis.

NOTE: The information presented on this page is for all consolidated assets, inclusive of our industrial properties. During the third quarter of 2011, Piedmont revised its definitions of incremental and non-incremental capital expenditures in order to conform with the more broadly accepted definitions for such terms by other office REITs. Our revised definitions of these measures can be found on pages 35 and 36. Capital expenditures have been restated for all prior periods in order to provide a consistent basis for comparison.

⁽¹⁾ Commitments are unexpired contractual tenant improvement obligations for leases executed in current and prior periods that have not yet been incurred and have not otherwise been presented on Piedmont's financial statements. The four largest commitments total approximately $75.8 million, or 55% of total outstanding commitments.

NOTE: This information is presented for our consolidated office assets only. Short-term leases (leases for a term of less than one year) are excluded from this information.

⁽¹⁾ For leases under which a tenant may use, at its discretion, a portion of its tenant improvement allowance for expenses other than those related to improvements to its space, an assumption is made that the tenant elects to use any such portion of its tenant improvement allowance for improvements to its space prior to the commencement of its lease, unless the Company is notified otherwise by the tenant. This assumption is made based upon the historical tenant improvement allowance usage patterns of the Company’s tenants.

⁽²⁾ During 2011, we completed two large, 15-year lease renewals with significant capital commitments: NASA at Two Independence Square in Washington, D.C. and GE at 500 West Monroe Street in Chicago, IL. If the costs associated with these renewals were to be removed from the average committed capital cost calculation, the average committed capital cost per square foot per year of lease term for renewal leases in 2011 would be $2.80.

Supplemental Definitions

Included in this section are management’s statements regarding certain non-GAAP financial measures provided in this supplemental report and reasons why management believes that these measures provide useful information to investors about the Company’s financial condition and results of operations. Reconciliations of these non-GAAP measures are included within pages 38-40.

Adjusted Funds From Operations (“AFFO”): AFFO is calculated by deducting from Core FFO non-incremental capital expenditures and acquisition-related costs and adding back non-cash items including non-real estate depreciation, straight lined rents and fair value lease revenue, non-cash components of interest expense and compensation expense, and by making similar adjustments for unconsolidated partnerships and joint ventures. Although AFFO may not be comparable to that of other REITs, we believe it provides a meaningful indicator of our ability to fund cash needs and to make cash distributions to equity owners. AFFO is a non-GAAP financial measure and should not be viewed as an alternative measurement of our operating performance to net income, as an alternative to net cash flows from operating activities or as a measure of our liquidity.

Annualized Lease Revenue (“ALR”): ALR is calculated by multiplying (i) rental payments (defined as base rent plus operating expense reimbursements, if payable by the tenant on a monthly basis under the terms of a lease that have been executed, but excluding a) rental abatements and b) rental payments related to executed but not commenced leases for space that was covered by an existing lease), by (ii) 12. In instances in which contractual rents or operating expense reimbursements are collected on an annual, semi-annual, or quarterly basis, such amounts are multiplied by a factor of 1, 2, or 4, respectively, to calculate the annualized figure. For leases that have been executed but not commenced relating to un-leased space, ALR is calculated by multiplying (i) the monthly base rental payment (excluding abatements) plus any operating expense reimbursements for the initial month of the lease term, by (ii) 12. Unless stated otherwise, this measure excludes our industrial properties and unconsolidated joint venture interests.

Core EBITDA: Core EBITDA is defined as net income before interest, taxes, depreciation and amortization and incrementally removing any impairment losses, gains or losses from sales of property, or other extraordinary items. We do not include impairment losses in this measure because we feel these types of losses create volatility in our earnings and make it difficult to determine the earnings generated by our ongoing business. We believe Core EBITDA is a reasonable measure of our liquidity. Core EBITDA is a non-GAAP financial measure and should not be viewed as an alternative measurement of cash flows from operating activities or other GAAP basis liquidity measures. Other REITs may calculate Core EBITDA differently and our calculation should not be compared to that of other REITs.

Core Funds From Operations (“Core FFO”): We calculate Core FFO by starting with FFO, as defined by NAREIT, and adjusting for certain non-recurring items such as gains or losses on the early extinguishment of debt, acquisition-related costs and other extraordinary items. Such items create significant earnings volatility. We believe Core FFO provides a meaningful measure of our operating performance and more predictability regarding future earnings potential. Core FFO is a non-GAAP financial measure and should not be viewed as an alternative measurement of our operating performance to net income; therefore, it should not be compared to other REITs' equivalent to Core FFO.

Core Net Operating Income (“Core NOI”): Core NOI is defined as real estate operating income with the add-back of corporate general and administrative expense, depreciation and amortization, and casualty and impairment losses and the deduction of income and expense associated with lease terminations and income associated with property management performed by Piedmont for other organizations. We present this measure on an accrual basis and a cash basis, which eliminates the effects of straight lined rents and fair value lease revenue. The company uses this measure to assess its operating results and believes it is important in assessing operating performance. Core NOI is a non-GAAP measure which does not have any standard meaning prescribed by GAAP and therefore may not be comparable to similar measures presented by other companies.

EBITDA: EBITDA is defined as net income before interest, taxes, depreciation and amortization. We believe EBITDA is an appropriate measure of our ability to incur and service debt. EBITDA should not be considered as an alternative to cash flows from operating activities, as a measure of our liquidity or as an alternative to net income as an indicator of our operating activities. Other REITs may calculate EBITDA differently and our calculation should not be compared to that of other REITs.

Funds From Operations (“FFO”): FFO is calculated in accordance with the current National Association of Real Estate Investment Trusts (“NAREIT”) definition. NAREIT currently defines FFO as net income (computed in accordance with GAAP), excluding gains or losses from sales of property and impairment losses, adding back depreciation and amortization on real estate assets, and after the same adjustments for unconsolidated partnerships and joint ventures. These adjustments can vary among owners of identical assets in similar conditions based on historical cost accounting and useful-life estimates. FFO may provide valuable comparisons of operating performance between periods and with other REITs. FFO is a non-GAAP financial measure and should not be viewed as an alternative measurement of our operating performance to net income. We believe that FFO is a beneficial indicator of the performance of an equity REIT. However, other REITs may not define FFO in accordance with the NAREIT definition, or may interpret the current NAREIT definition differently than we do; therefore, our computation of FFO may not be comparable to that of such other REITs.

Incremental Capital Expenditures: Incremental Capital Expenditures are defined as capital expenditures of a non-recurring nature that incrementally enhance the underlying assets' income generating capacity. Tenant improvements, leasing commissions, building capital and deferred lease incentives (“Leasing Costs”) incurred to lease space that was vacant at acquisition, Leasing Costs for spaces vacant for greater than one year, Leasing Costs for spaces at newly acquired properties for which in-place leases expire shortly after acquisition, improvements associated with the expansion of a building and renovations that change the underlying classification of a building are included in this measure.

Supplemental Definitions

NOI from Unconsolidated Joint Ventures: NOI from Unconsolidated Joint Ventures is defined as Core NOI attributable to our interests in eight properties owned through unconsolidated partnerships. We present this measure on an accrual basis and a cash basis, which eliminates the effects of straight lined rents and fair value lease revenue. NOI from Unconsolidated Joint Ventures is a non-GAAP measure and therefore may not be comparable to similarly defined data provided by other REITs.

Non-Incremental Capital Expenditures: Non-Incremental Capital Expenditures are defined as capital expenditures of a recurring nature related to tenant improvements and leasing commissions that do not incrementally enhance the underlying assets' income generating capacity. We exclude first generation tenant improvements and leasing commissions from this measure, in addition to other capital expenditures that qualify as Incremental Capital Expenditures, as defined above.

Same Store Net Operating Income (“Same Store NOI”): Same Store NOI is calculated as the Core NOI attributable to the properties owned or placed in service during the entire span of the current and prior year reporting periods. Same Store NOI excludes amounts attributable to industrial properties and unconsolidated joint venture assets. We present this measure on an accrual basis and a cash basis, which eliminates the effects of straight lined rents and fair value lease revenue. We believe Same Store NOI is an important measure of comparison of our stabilized properties' operating performance. Other REITs may calculate Same Store NOI differently and our calculation should not be compared to that of other REITs.

Same Store Properties: Same Store Properties is defined as properties owned or placed in service during the entire span of the current and prior year reporting periods. Same Store Properties excludes industrial properties and unconsolidated joint venture assets. We believe Same Store Properties is an important measure of comparison of our stabilized portfolio performance.

Risks, Uncertainties and Limitations

Certain statements contained in this supplemental package constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We intend for all such forward-looking statements to be covered by the safe-harbor provisions for forward-looking statements contained in Section 27A of the Securities Act and Section 21E of the Exchange Act, as applicable. Such information is subject to certain risks and uncertainties, as well as known and unknown risks, which could cause actual results to differ materially from those projected or anticipated. Therefore, such statements are not intended to be a guarantee of our performance in future periods. Such forward-looking statements can generally be identified by our use of forward-looking terminology such as “may,” “will,” “expect,” “intend,” “anticipate,” “believe,” “continue” or similar words or phrases that are predictions of future events or trends and which do not relate solely to historical matters.

The following are some of the factors that could cause our actual results and expectations to differ materially from those described in our forward-looking statements: our ability to successfully identify and consummate suitable acquisitions; the demand for office space, rental rates and property values may continue to lag the general economic recovery; our $500 Million Unsecured Facility matures in August 2012 and a failure to renew this facility could cause our business, results of operations, cash flows, financial condition and access to capital to be adversely affected; lease terminations or lease defaults, particularly by one of our large lead tenants; the impact of competition on our efforts to renew existing leases or re-let space; changes in the economies and other conditions of the office market in general and of the specific markets in which we operate; economic and regulatory changes; additional risks and costs associated with directly managing properties occupied by government tenants; adverse market and economic conditions and related impairments to our assets, including, but not limited to, receivables, real estate assets and other intangible assets; availability of financing; costs of complying with governmental laws and regulations; uncertainties associated with environmental and other regulatory matters; potential changes in the political environment and reduction in federal and/or state funding of our government tenants; we are and may continue to be subject to litigation; our ability to continue to qualify as a REIT under the Internal Revenue Code; and other factors detailed in our most recent Annual Report on Form 10-K and other documents we file with the Securities and Exchange Commission.

Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this supplemental report. We cannot guarantee the accuracy of any such forward-looking statements contained in this supplemental report, and we do not intend to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise.
