Piedmont Office Realty Trust Reports Third Quarter Results

ATLANTA, November 10, 2010—Piedmont Office Realty Trust, Inc. (“Piedmont” or the “Company”) (NYSE:PDM), an owner of primarily Class A properties located predominantly in the ten largest U.S. office markets, today announced its results for the quarter ended September 30, 2010.

Highlights for the Three Months Ended September 30, 2010:

• Achieved funds from operations (“FFO”) of $0.45 per diluted share compared to $0.21 per diluted share for the same quarter in 2009 and core funds from operations (“Core FFO”) of $0.45 per diluted share, which excludes impairment charges, as compared to $0.45 per diluted share in Core FFO for the quarter ended September 30, 2009.

• Increased same store net operating income 1.7 percent to $90.8 million for the quarter ended September 30, 2010 as compared to $89.4 million for the three months ended September 30, 2009.

• Leased over 600,000 square feet in the quarter, including approximately 587,000 square feet of office space at the Company’s 74 consolidated office properties.

• Completed the acquisition of a newly constructed 142,427 square foot Class A office building for $55 per square foot in Atlanta, GA.

• Subsequent to quarter end, completed the acquisition of two office buildings with approximately 384,000 combined square feet in Minneapolis, MN for $65.6 million.

Donald A. Miller, CFA, President and Chief Executive Officer, stated, “We delivered strong third quarter operating results while also executing on our selective acquisition strategy. We continue to focus on attracting and retaining high quality tenants in long-term leases at our properties, and we signed approximately 587,000 square feet of office leases in our 74 consolidated office properties during the quarter. We believe that our high quality assets, the strength of our balance sheet, and our reputation as a reliable and well capitalized landlord give Piedmont an advantage in effectively competing for tenants. We have been patiently seeking the appropriate properties to expand our portfolio. Since the end of the second quarter, we have strategically deployed $73.5 million in three properties, enhancing our presence in key strategic markets.”

Results for the Third Quarter ended September 30, 2010

All prior period per share amounts have been retroactively restated to reflect the stockholder-approved recapitalization of our common stock. Current period per share amounts reflect the issuance of 13.8 million shares of common stock. Both the recapitalization and issuance of stock

occurred during the first quarter of 2010.

Piedmont’s net income available to common stockholders was $40.6 million, or $0.23 per diluted share, for the third quarter of 2010, compared with a net loss of $8.3 million or ($0.05) per diluted share for the third quarter of 2009. The net loss in the prior year period was the result of a $37.6 million in impairment charges recognized in the third quarter of 2009. The 2010 net income results reflected approximately $0.03 in dilution per share related to the issuance of 13.8 million shares of common stock during first quarter of 2010. FFO for the quarter totaled $77.9 million, or $0.45 per diluted share as compared to FFO of $32.8 million or $0.21 per diluted share for the quarter ended September 30, 2009. Core FFO, which excludes impairment charges, was $0.45 per diluted share for both the current and prior year quarters ended September 30. Adjusted FFO (“AFFO”) for the third quarter of 2010 totaled $61.5 million, or $0.36 per diluted share, as compared to $61.4 million, or $0.39 per diluted share, in the third quarter of 2009.

Revenues for the quarter ended September 30, 2010 totaled $145.5 million compared to $148.9 million in the same period a year ago. Property operating expenses of $46.6 million in the third quarter of 2010 declined 19 percent from $57.6 million in the third quarter of 2009. Operating revenues and expenses during the third quarter of 2010 included the previously indicated estimate of $4.2 million of termination fee income and $5.6 million in lower property tax expenses (net of lower tenant reimbursement revenue), respectively, which combined, contributed $0.06 per diluted share to third quarter 2010’s FFO. Same store net operating income for the quarter was $90.8 million, 1.7 percent higher than the $89.4 million for the third quarter ended 2009.

Leasing Update

During the third quarter of 2010, the Company executed over 600,000 square feet of leasing, including approximately 587,000 square feet of office leases in its consolidated office properties, spread throughout its markets. Roughly 389,000 square feet, or 66 percent, of the office leases were renewals and 198,000 square feet, or 34 percent, were new leases or expansion leases with existing tenants. As of September 30, 2010, the Company’s office portfolio was 89.0 percent leased with a weighted average lease term remaining of 5.6 years. The decrease in the leased percentage of the Company’s office portfolio from 89.8 percent as of June 30, 2010 to 89.0 percent as of September 30, 2010 was primarily related to the acquisition of a vacant 142,427 square foot building in the Atlanta market at the end of the quarter. Excluding our newly acquired building in Atlanta from consideration, the portfolio was 89.7 percent leased as of September 30, 2010. The Company is actively managing its upcoming lease expirations including several large 2011 and 2012 lease expirations.

Dividend

During the quarter ended September 30, 2010, the company paid a quarterly dividend in the amount of $0.315 per share for all classes of common stock.

Balance Sheet and Capital Markets Activities

As of September 30, 2010, Piedmont’s total gross real estate assets were $4.6 billion with total debt of $1.4 billion. The Company’s total debt-to-gross assets ratio at the end of the quarter was 26.6 percent and the quarter’s net debt (total debt less cash and cash equivalents) to annualized core EBITDA ratio was 3.5 times. The Company’s fixed charge coverage ratio was 5.5 times. As of September 30, 2010, Piedmont had cash and capacity on its unsecured credit line of approximately $554 million and no debt maturities in 2010. As previously announced, Piedmont has entered into a binding purchase and sale agreement to sell its 111 Sylvan Avenue property in New Jersey for $55.0 million and the transaction is expected to close in December 2010.

Acquisitions

Piedmont acquired one Class A office building during the quarter in the Atlanta market. The acquired property was Suwanee Gateway One, a five-story, 142,427 square foot building located in the I-85 corridor of northeastern metropolitan Atlanta. The Company acquired the building for approximately $7.9 million, or $55 per square foot. The building was constructed to meet LEED Silver standards and is available for lease.

Subsequent to Quarter End

Acquisitions and Dispositions

The company purchased, for $65.6 million, two Class A eight-story office buildings (the “Meridian Crossings Buildings”) containing approximately 384,000 combined rentable square feet and located in the Minneapolis, MN market. The Meridian Crossings Buildings, which were completed in 1997 and 1998, are primarily leased through 2023 to U.S. Bancorp, an existing tenant within the Piedmont portfolio. The two buildings combined are approximately 96 percent leased.

Piedmont, along with its joint venture partners, completed the sale of a property, 14400 Hertz Quail Springs Parkway in Oklahoma City, Oklahoma for $5.3 million, of which Piedmont’s proportionate share was approximately 4 percent.

Share Conversion

On November 7, 2010, all of Piedmont’s 39.7 million shares of Class B-2 common stock converted to Class A common stock. The final tranche of Class B common stock is scheduled to convert to Class A common stock on January 30, 2011.

Dividend

On November 9, 2010, the Board of Directors of Piedmont declared dividends for the fourth quarter of 2010 in the amount of $0.315 per share on all classes of outstanding common shares of Piedmont to stockholders of record as of the close of business on December 1, 2010. Such dividends are to be paid on December 15, 2010.

Guidance for 2010

The Company is adjusting its financial guidance for full-year 2010 to the upper end of its previously announced range based upon management’s expectations as follows:

	Low			High
Core FFO in millions (excludes impairment charges)	$	275	–	$	282
Core FFO per diluted share (excludes impairment charges)	$	1.61	–	$	1.65

Note that individual quarters may fluctuate on both a cash basis and an accrual basis due to timing of repairs and maintenance, capital expenditures 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 release.

Non-GAAP Financial Measures

This release contains certain supplemental non-GAAP financial measures such as FFO, AFFO, Core FFO, Same store net operating income, and Core EBITDA. See below for definitions and reconciliations of these metrics to their most comparable GAAP metric.

⁽¹⁾ Includes adjustments for wholly-owned properties and for our proportionate ownership in unconsolidated joint ventures.

⁽³⁾ 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.

*Definitions

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, adding back depreciation and amortization on real estate assets, and after the same adjustments for unconsolidated partnerships and joint ventures. Such factors 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.

Core Funds From Operations (“Core FFO”): We calculate Core FFO by starting with FFO, as defined by NAREIT, and adjust for certain non-recurring items such as impairment losses 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.

Adjusted Funds From Operations (“AFFO”): AFFO is calculated by deducting from Core FFO non-incremental capital expenditures 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.

*Definitions

Core EBITDA: Core EBITDA is defined as net income before interest, taxes, depreciation and amortization and incrementally adding back any impairment losses and 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 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 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.

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. We present this measure on 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.

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 predominately in large U.S. office markets and leased principally to high-credit-quality tenants. Since its first acquisition in 1998, the Company has acquired through September 30, 2010 approximately $5.5 billion of office and industrial properties (inclusive of joint ventures). Rated as an investment-grade company by Standard & Poor’s and Moody’s, Piedmont has maintained a low-leverage strategy while acquiring its properties. Approximately 83% 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.

This data supplements the information provided in our reports filed with the Securities and Exchange Commission.

(1) The definition for Annualized Lease Revenue can be found on page 29.

(2) Our office portfolio currently consists of 74 properties (exclusive of our equity interests in eight properties owned through unconsolidated joint ventures and our two industrial properties). We acquired one newly-built, vacant building totaling approximately 142,000 square feet during the third quarter of 2010. On October 1, 2010, we acquired Meridian Crossings, two buildings comprised of 384,000 square feet and 96% leased; statistical information for Meridian Crossings is not included in our portfolio information as of September 30, 2010 presented herein.

(3) Calculated as leased square footage on September 30, 2010 plus square footage associated with new leases signed for currently vacant spaces divided by total rentable square footage, expressed as a percentage. This measure is presented for our 74 office properties and excludes industrial and unconsolidated joint venture properties. On September 28, 2010, we acquired one building totaling approximately 142,000 square feet that is currently vacant; if we excluded this building from consideration for consistent comparison to prior periods, our percent leased would be 89.7%, as compared to 89.8% at June 30, 2010.

(4) Our Class A common stock was listed on the New York Stock Exchange on February 10, 2010; there is no market data as of December 31, 2009. As of September 30, 2010, our Class B-2 and Class B-3 common stock (collectively, our “Class B common stock”) were not listed on a national securities exchange and there was no established market for such shares. We have used the closing price of the Class A common stock at the relevant period end for the purposes of the calculations regarding market capitalization herein.

(5) Weighted average fully diluted shares outstanding are presented on a year-to-date basis for each period.

(6) On January 22, 2010, we filed an amendment to our charter to effect a recapitalization of our common stock as described further in our SEC filings. The recapitalization had the effect of a one-for-three reverse stock split. Prior period share and per share information in this report has been restated to reflect this recapitalization.

(7) During the second quarter of 2010, the company opened a regional office in Boston. The opening of that office is the primary reason for the increase in number of employees.

Financial Highlights

As of September 30, 2010

On January 22, 2010, we filed an amendment to our charter to effect a recapitalization of our common stock as described further in our Securities and Exchange Commission (“SEC”) filings. Upon the effectiveness of the recapitalization, each share of our outstanding common stock converted automatically into: (a) 1/12th of a share of our Class A common stock; plus (b) 1/12th of a share of our Class B-1 common stock; plus (c) 1/12th of a share of our Class B-2 common stock; plus (d) 1/12th of a share of our Class B-3 common stock. The recapitalization had the effect of a one-for-three reverse stock split. Prior period share and per share information in this report has been restated to reflect this recapitalization. Class B-1 common stock converted automatically into Class A common stock on August 9, 2010; Class B-2 common stock converted subsequent to quarter end into Class A common stock on November 7, 2010; and Class B-3 common stock will convert to Class A common stock on January 30, 2011.

Financial Results ⁽¹⁾

- Funds from operations (FFO) for the quarter ended September 30, 2010 was $77.9M, or $0.45 per share (diluted), compared to $32.8M, or $0.21 per share (diluted), for the same quarter in 2009. FFO for the nine months ended September 30, 2010 was $203.7M, or $1.20 per share (diluted), compared to $169.8M, or $1.07 per share (diluted), for the same period in 2009. The increase in FFO from 2009 to 2010 was primarily due to the recognition of a $53,000 impairment charge associated with one joint venture interest in 2010 as compared to the recognition of $37.6M in impairment charges on three wholly-owned properties and one joint venture interest in the third quarter of 2009. Additionally, lower property operating expenses in 2010 driven primarily by lower property taxes contributed to the year-over-year increase.

- Core funds from operations (Core FFO) for the quarter ended September 30, 2010 was $77.9M, or $0.45 per share (diluted), compared to $70.5M, or $0.45 per share (diluted), for the same quarter in 2009. Core FFO for the nine months ended September 30, 2010 was $213.3M, or $1.25 per share (diluted), compared to $207.4M, or $1.31 per share (diluted), for the same period in 2009. The increase in Core FFO for the three months and the nine months ended September 30, 2010 as compared to the same periods in 2009 was primarily due to lower property taxes, partially offset by lower tenant reimbursements. The decrease in Core FFO per share for the nine months ended September 30, 2010 as compared to the same period in 2009 was primarily due to the dilutive effect of the 13.8 million shares of Class A common stock issued when the Company listed on the NYSE in February 2010.

- Adjusted funds from operations (AFFO) for the quarter ended September 30, 2010 was $61.5M, or $0.36 per share (diluted), compared to $61.4M, or $0.39 per share (diluted), for the same quarter in 2009. AFFO for the nine months ended September 30, 2010 was $177.6M, or $1.04 per share (diluted), compared to $181.0M, or $1.14 per share (diluted), for the same period in 2009. AFFO for the quarter ended September 30, 2010 was similar to that of 2009; while capital expenditures were higher in 2010 as a result of new leasing activity, property operating expenses were lower as described above. The decrease in AFFO for the nine months ended September 30, 2010 as compared to that of 2009 was primarily due to increased capital expenditures and greater straight line rent adjustments in 2010, partially offset by lower property operating expenses. The AFFO per share results are also lower due to the dilutive effect of the 13.8 million shares of Class A common stock issued when the Company listed on the NYSE in February 2010.

- During the quarter ended September 30, 2010, the Company paid to stockholders a quarterly dividend in the amount of $0.315 per share for all classes of common stock. The Company’s dividend payout percentage for the nine months ended September 30, 2010 was 76.2% of Core FFO and 91.5% of AFFO.

Operations

- On a square footage basis, our portfolio was 89.0% leased as of September 30, 2010 as compared to 89.8% and 90.1% at June 30, 2010 and December 31, 2009, respectively. The decrease in the office portfolio leased percentage during the quarter is primarily related to the acquisition of a vacant 142,000 square foot building in the Atlanta market at the end of the quarter. Excluding the newly acquired building from consideration, the portfolio would have been 89.7% leased as of September 30, 2010, with leased square footage decreasing approximately 6,000 square feet from the previous quarter end. The decrease in leased percentage since the prior year end is primarily due to 99,000 square feet being vacated in January 2010 by Kirkland & Ellis in Chicago and the newly acquired vacant building in the Atlanta market.

- The weighted average remaining lease term of our portfolio was 5.6 years⁽²⁾ as of September 30, 2010 as compared to 5.9 years at December 31, 2009.

- As noted in our December 31, 2009 Quarterly Supplemental Information, 6.8% of our Annualized Lease Revenue was set to expire in 2010 and a majority of this expiration was to take place in the fourth quarter. During the three months ended September 30, 2010, the Company completed 587,000 square feet of office leasing at our 74 consolidated office properties. We executed renewal leases for 389,000 square feet and new tenant leases for 198,000 square feet, bringing the year-to-date total office leasing activity to 1,325,000 square feet, with an average committed capital cost of $3.50 per square foot per year of lease term. From an industrial leasing perspective, we did not execute any new leases during the quarter, maintaining the same year-to-date total industrial leasing activity of 487,000 square feet with an average committed capital cost of $0.21 per square foot per year of lease term.

⁽¹⁾ FFO, Core FFO and AFFO are supplemental non-GAAP financial measures. See pages 29-30 for definitions of non-GAAP financial measures. See pages 12 and 34 for reconciliations of FFO, Core FFO and AFFO to Net Income.

⁽²⁾ Remaining lease term (after taking into account leases which had been executed but not commenced as of September 30, 2010) is weighted based on Annualized Lease Revenue, as defined on page 29.

Financial Highlights

As of September 30, 2010

Financing and Capital Activity

- As of September 30, 2010, our ratio of debt to total market capitalization was 30.0%; our ratio of debt to gross real estate assets was 30.7%; and our ratio of debt to total gross assets was 26.6%.

- On May 5, 2010, Piedmont entered into a binding contract to sell the 111 Sylvan Avenue property in Englewood Cliffs, NJ. The purchaser has completed its due diligence study of the asset and its deposit of 10% of the agreed upon purchase price of $55 million is non-refundable. The transaction is scheduled to close in December 2010, which will allow Piedmont to recognize the cash flow of the existing lease with Citicorp through its current expiration in November 2010. Piedmont has reclassified 111 Sylvan Avenue from real estate assets held-for-use to real estate assets held-for-sale as of May 5, 2010. During the second quarter of 2010, Piedmont recorded a $9.6 million impairment charge as a result of adjusting the asset to estimated fair value. The results from operations for the asset are now presented in discontinued operations.

- During the third quarter of 2010, Piedmont purchased Suwanee Gateway One, a 142,000 square foot building located in the Interstate 85 North corridor of the northeastern Atlanta, GA market. The building was built in 2008 and is not currently leased. Piedmont purchased the building from the former lender for approximately $55 per square foot. The building is well located adjacent to one of Atlanta's major interstate highways. Given the location, management's knowledge of the market, the new construction, and the low cost basis, Piedmont believes the transaction provides a good value-add opportunity in an opportunistic market.

- During the third quarter of 2010, Piedmont entered into a binding agreement to purchase Meridian Crossings, two buildings totaling 384,000 square feet in suburban Minneapolis, MN. The buildings are well located at the intersection of Interstates 35W and 494 and were constructed in 1997 and 1998. The tenant of approximately 88% of the total square footage in both buildings is U.S. Bancorp, a tenant with which Piedmont has significant existing business relationships. U.S. Bancorp's lease extends through 2023. Piedmont completed the purchase of Meridian Crossings subsequent to quarter end; therefore, statistical information presented herein as of September 30, 2010 does not include the Meridian Crossings buildings.

- On September 24, 2010, Piedmont, along with its joint venture partners, entered into a binding agreement to sell 14400 Hertz Quail Springs Parkway, a 57,000 square foot building in Oklahoma City, OK. The building is leased through 2015 to business communications firm Avaya. Approximately 10% of the agreed upon purchase price of $5.3 million was non-refundable as of the end of the third quarter of 2010. The sale of the property was completed subsequent to quarter end. Piedmont’s ownership in the property was approximately 4%.

- On August 9, 2010, all of Piedmont's 39.7 million shares of Class B-1 common stock converted to Class A common stock.

Subsequent Events

- On October 1, 2010, Piedmont completed the purchase of Meridian Crossings in suburban Minneapolis, MN.

- On October 15, 2010, Piedmont completed the sale of one joint venture property, 14400 Hertz Quail Springs Parkway in Oklahoma City, OK.

- On November 7, 2010, all of Piedmont's 39.7 million shares of Class B-2 common stock converted to Class A common stock.

- On November 9, 2010, the board of directors of Piedmont declared dividends for the fourth quarter of 2010 in the amount of $0.315 per share on all classes of outstanding common shares of Piedmont to stockholders of record as of the close of business on December 1, 2010. The dividends are payable on December 15, 2010.

Guidance for 2010

- The Company is adjusting its financial guidance for full-year 2010 to the upper end of its previously announced range based upon management’s expectations as follows:

	Low		High
Core Funds from Operations (excludes impairment charges)	$275	-		282 million
Core Funds from Operations per diluted share (excludes impairment charges)	$1.61	-		1.65

Our $9.6 million impairment charge on the 111 Sylvan Avenue property does not have an impact on our reported Core FFO, but it does impact FFO as originally estimated by roughly $0.055 per share. The opportunity to sell 111 Sylvan Avenue was not contemplated in our original FFO guidance. Note that individual quarters may fluctuate on both a cash and an accrual basis due to timing of repairs and maintenance, capital expenditures 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⁾ Percent leased represents 74 office properties and excludes industrial and unconsolidated joint venture properties. Percent leased decreased in the first quarter of 2010 as compared to the prior period primarily due to Kirkland & Ellis vacating 99,000 square feet at Aon Center in Chicago, IL. Percent leased decreased in the third quarter of 2010 as compared to the prior period primarily due to the acquisition of Suwanee Gateway One, a newly-built, vacant building consisting of 142,000 square feet; if we excluded this building from consideration for consistent comparison to prior periods, our percent leased would have been 89.7%.

⁽²⁾ Total operating expenses and real estate operating income in the third quarter of 2009 include $35.1 million in impairment charges recognized on three wholly-owned assets and in the second quarter of 2010 include a $9.6 million impairment charge on one wholly-owned asset.

⁽³⁾ Impairment losses include losses for both wholly-owned and unconsolidated joint venture assets.

⁽⁴⁾ Core EBITDA and AFFO have been adjusted to exclude impairments on real estate assets as shown on pages 32 and 34.

⁽⁵⁾ Net debt is calculated as total debt minus cash and cash equivalents.

⁽⁶⁾ Core EBITDA margin is calculated as Core EBITDA divided by total revenues (including revenues associated with discontinued operations).

⁽⁷⁾ Fixed charge coverage is calculated as Core EBITDA divided by the sum of interest expense, principal amortization, capitalized interest and preferred dividends. We had no capitalized interest, principal amortization or preferred dividends during the three months ended September 30, 2010.

⁽⁸⁾ Core EBITDA is annualized for the purposes of this calculation.

(1) During the three months ended March 31, 2010, the board of directors terminated the share redemption plan. We are no longer required by GAAP to reclassify any of our common stock outstanding as redeemable common stock.

(2) On January 22, 2010, we filed an amendment to our charter to effect a recapitalization of our common stock as described further in our SEC filings. Upon the effectiveness of the recapitalization, each share of our outstanding common stock converted automatically into: (a) 1/12th of a share of our Class A common stock; plus (b) 1/12th of a share of our Class B-1 common stock; plus (c) 1/12th of a share of our Class B-2 common stock; plus (d) 1/12th of a share of our Class B-3 common stock. The recapitalization had the effect of a one-for-three reverse stock split. Prior period share and per share information in this report has been restated to reflect this recapitalization.

⁽¹⁾ Includes amounts attributable to our unconsolidated joint venture assets.

⁽²⁾ The increase in Chicago Same Store Net Operating Income for the three months ended September 30, 2010 as compared to the same period in 2009 is primarily due to accrual adjustments for property taxes. Assessed values for several buildings resulting from triennial reassessments and subsequent appeals were less than budgeted. The decrease in Chicago Same Store Net Operating Income for the nine months ended September 30, 2010 as compared to the same period in 2009 is primarily related to a rental abatement concession associated with a lease renewal at Windy Point I in Schaumburg, IL, as well as the previously announced 99,000 square foot partial lease expiration with Kirkland & Ellis at Aon Center in Chicago, IL, offset by the lower property tax assessments described above.

⁽³⁾ The decrease in New York Same Store Net Operating Income for the nine months ended September 30, 2010 as compared to the same period in 2009 is primarily related to a rental abatement in 2010 associated with the lease restructure/extension with the State of New York as well as utility credits to tenants for prior year charges at 60 Broad Street in New York, NY.

⁽⁴⁾ The decrease in Los Angeles Same Store Net Operating Income for the three months ended September 30, 2010 as compared to the same period in 2009 is primarily due to a rental abatement in 2010 associated with the commencement of the renewal period for the Nestle lease at 800 North Brand Boulevard in Glendale, CA. The decrease in Los Angeles Same Store Net Operating Income for the nine months ended September 30, 2010 as compared to the same period in 2009 is primarily related to the rental abatement mentioned in the preceding sentence. Additional items contributing to the decrease in Los Angeles Same Store Net Operating Income for the nine months ended September 30, 2010 are a lease default during 2009 by a bank that leased 25,000 square feet and the recognition of holdover rent in 2009 for a lease that terminated in 2008 both at our 1901 Main Street building in Irvine, CA.

⁽⁵⁾ The increase in Other Same Store Net Operating Income for the three months ended September 30, 2010 and the nine months ended September 30, 2010 is due to a number of factors, the largest of which is the phased lease commencement for First Data Corporation for 184,000 square feet at Glenridge Highlands Two in Atlanta, GA during 2009.

⁽¹⁾ All of Piedmont’s outstanding debt as of September 30, 2010 is interest-only debt.

⁽²⁾ Amount represents the outstanding balance as of September 30, 2010 on the $500 million unsecured line of credit, which matures August 2011. Management intends to exercise the one-year extension option to extend the maturity date to August 2012. The payment of a 15 bp fee will be required to extend the term of this facility.

⁽³⁾ The interest rate on the currently unused $500 million unsecured line of credit is equal to the weighted average interest rate on all outstanding draws as of September 30, 2010. Piedmont may select from multiple interest rate options with each draw, including the prime rate and various length LIBOR locks. All LIBOR selections are subject to an additional spread of 0.475% over the selected rate based on Piedmont’s current credit rating.

⁽⁴⁾ The $250 million unsecured term loan has a stated variable rate; however, Piedmont entered into interest rate swap agreements which effectively fix the interest rate on this loan at 2.36% through June 28, 2011.

Leases executed for spaces excluded from analysis (5)		276

⁽¹⁾ Calculated as leased square footage on September 30, 2010 plus square footage associated with new leases signed for currently vacant spaces divided by total rentable square footage, 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⁾ The population analyzed consists of office leases executed during the period (retail leases as well as leases associated with our industrial properties and our unconsolidated joint venture assets were excluded from this analysis). For spaces that had been vacant for less than one year, the rents last in effect for the previous lease were compared to the initial rents of the new lease. Spaces that had been vacant for greater than one year were excluded from 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. 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 space had been vacant for greater than one year.

⁽¹⁾ Expiring lease revenue is calculated as expiring square footage multiplied by the rent per square foot of the tenant currently leasing the space.

⁽²⁾ The 2010 expiration data includes the expiration of the Citicorp lease at 111 Sylvan Avenue, an asset that is classified as held-for-sale. If that lease were not included, our 2010 expiration exposure would be 2,000 square feet and $100,000 in expiring lease revenue.

⁽³⁾ Total expiring lease revenue in any given year will not tie to the expiring Annualized Lease Revenue presented on the Lease Expiration Schedule as the Lease Expiration Schedule accounts for revenue effects of newly signed leases. Expirations in the Lease Expiration Schedule reflect rental rates of newly executed leases, effectively incorporating known roll ups and roll downs.

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 presented on pages 32-35.

Adjusted Funds From Operations (“AFFO”): AFFO is calculated by deducting from Core FFO non-incremental capital expenditures 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 rental abatements and 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 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 adding back any impairment losses and 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 impairment losses 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, adding back depreciation and amortization on real estate assets, and after the same adjustments for unconsolidated partnerships and joint ventures. Such factors 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 incurred to lease space that was dark at 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.

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. 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. We believe Same Store Properties is an important measure of comparison of our stabilized portfolio performance.
