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. Since its first acquisition in 1998, the Company has acquired $5.9 billion of office and industrial properties (inclusive of joint ventures) through September 30, 2011. 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 84% 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 and should be reviewed in conjunction with such filings.

⁽²⁾  As of September 30, 2011, our office portfolio consisted of 79 properties (exclusive of our equity interests in five properties owned through unconsolidated joint ventures and our two industrial properties). During the second quarter of 2011, we sold Eastpointe Corporate Center, a 156,000 square foot building located in Issaquah, WA, and 5000 Corporate Court, a 264,000 square foot building located in Holtsville, NY, and we purchased 225 and 235 Presidential Way, two buildings comprised of 440,000 square feet and located in Woburn, MA.

⁽³⁾  Calculated as leased square footage on September 30, 2011 plus square footage associated with executed new leases for currently vacant spaces divided by total rentable square footage, expressed as a percentage. This measure is presented for our 79 office properties and excludes industrial and unconsolidated joint venture properties. Please refer to page 23 for additional analyses regarding Piedmont’s leased percentage.

⁽⁴⁾  Please refer to page 32 for information regarding value-add properties.

⁽⁵⁾  Total gross debt includes $120 million of debt associated with one held-for-sale asset, 35 West Wacker Drive.

⁽⁶⁾  Weighted average fully diluted shares outstanding are presented on a year-to-date basis for each period.

⁽⁷⁾  During 2011, the company hired a regional manager and additional staff for its New York, NY office. The opening of this office is the primary reason for the increase in number of employees.

Financial Highlights

As of September 30, 2011

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. The recapitalization had the effect of a one-for-three reverse stock split. All prior period per share data has been restated to give net effect to this one-for-three reverse stock split.

Financial Results⁽¹⁾                    

-  Funds from operations (FFO) for the quarter ended September 30, 2011 was $68.9 million, or $0.40 per share (diluted), compared to $77.9 million, or $0.45 per share (diluted), for the same quarter in 2010. FFO for the nine months ended September 30, 2011 was $205.4 million, or $1.19 per share (diluted), compared to $203.7 million, or $1.20 per share (diluted), for the same period in 2010. The decrease in FFO for the three months ended September 30, 2011 as compared to the same period in 2010 was principally related to one-time net property tax credits of approximately $3 million recognized in the third quarter of 2010, lower termination income in the third quarter of 2011, and reduced rental income due to a decrease in leased percentage and rental rate roll downs; these items were partially offset by operating income contributed from properties acquired during the past year. A contributor to the decrease in per share amount for FFO for the nine months ended September 30, 2011 as compared to the same period in 2010 was the dilutive effect of the 13.8 million shares of common stock issued when the Company listed on the NYSE in February 2010.

-  Core funds from operations (Core FFO) for the quarter ended September 30, 2011 was $69.2 million, or $0.40 per share (diluted), compared to $78.2 million, or $0.45 per share (diluted), for the same quarter in 2010. Core FFO for the nine months ended September 30, 2011 was $206.3 million, or $1.19 per share (diluted), compared to $213.7 million, or $1.26 per share (diluted), for the same period in 2010. The decrease in Core FFO for the three and the nine months ended September 30, 2011 was principally related to one-time net property tax credits of approximately $3 million recognized in the third quarter of 2010 and reduced rental income due to a decrease in leased percentage and rental rate roll downs; these items were partially offset by operating income contributed from properties acquired during the past year.

-  Adjusted funds from operations (AFFO) for the quarter ended September 30, 2011 was $50.0 million, or $0.29 per share (diluted), compared to $66.8 million, or $0.39 per share (diluted), for the same quarter in 2010. AFFO for the nine months ended September 30, 2011 was $156.9 million, or $0.91 per share (diluted), compared to $186.6 million, or $1.10 per share (diluted), for the same period in 2010. The decrease in AFFO for the nine months ended September 30, 2011 as compared to the same period in 2010 was primarily due to increased capital expenditures in 2011 associated with increased leasing activity.

-  During the quarter ended September 30, 2011, the Company paid to shareholders a quarterly dividend in the amount of $0.315 per share for its common stock. The Company’s dividend payout percentage for the nine months ended September 30, 2011 was 79% of Core FFO and 104% of AFFO.

Operations                                     

-  On a same store square footage leased basis, our portfolio was 87.8% leased as of September 30, 2011 as compared to 88.8% leased as of September 30, 2010. On a square footage basis, our total office portfolio was 86.4% leased as of September 30, 2011, as compared to 89.2% as of December 31, 2010 and 89.0% as of September 30, 2010. The decrease in the office portfolio leased percentage during the last several quarters is primarily related to the addition to the portfolio of several properties with significant vacancies, including 500 West Monroe Street in Chicago, IL, 1200 Enclave Parkway in Houston, TX, The Medici in Atlanta, GA, and Suwanee Gateway One in Suwanee, GA. Removing these value-add properties from the total portfolio statistics results in an 88.8% leased rate for our stabilized assets at September 30, 2011 as compared to an 89.7% leased rate at September 30, 2010. A primary contributor to the decrease in stabilized leased percentage over the previous year is the expiration of a 300,000 square foot lease at Windy Point II in Schaumburg, IL; approximately 16% of the space vacated by the tenant had been released as of the end of the third quarter of 2011. Please refer to page 23 for additional information.

-  The weighted average remaining lease term of our portfolio was 6.6 years⁽²⁾ as of September 30, 2011 as compared to 5.8 years at December 31, 2010.

-  During the three months ended September 30, 2011, the Company completed 907,000 square feet of leasing at our 79 consolidated office properties. We executed renewal leases for 566,000 square feet and new tenant leases for 342,000 square feet, bringing the year-to-date total office leasing activity to 2,930,000 square feet, with an average committed capital cost of $5.13 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 nine months ended September 30, 2011 was $4.49 and average committed capital cost per square foot per year of lease term for new leases during the same time period was $6.12. We did not execute any new leases during the quarter for our two industrial properties.

-  During the three months ended September 30, 2011, we retained⁽³⁾ tenants for 58% of the square footage associated with expiring leases. During the nine months ended September 30, 2011, we retained tenants for 70% of the square footage associated with expiring leases. This result compares to a 72% retention rate for the year ended December 31, 2010.

⁽¹⁾FFO, Core FFO and AFFO are supplemental non-GAAP financial measures. See pages 34-35 for definitions of non-GAAP financial measures. See pages 14 and 37 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 September 30, 2011) is weighted based on Annualized Lease Revenue, as defined on page 34.

⁽³⁾ Piedmont defines a retained tenant to include an existing tenant/occupant signing a lease for the premises it currently occupies or a tenant whose occupancy of a space is structured in a way to eliminate downtime for the space. Excluding the Zurich American Insurance Company lease expiration at Windy Point II in Schaumburg, IL, our retention rate for the three months ended September 30, 2011, would have been 74% and that for the nine months ended September 30, 2011, would have been 76%.

Financial Highlights

As of September 30, 2011

Financing and Capital Activity            

-  As of September 30, 2011, our ratio of gross debt to total gross assets was 29.9%, our ratio of gross debt to gross real estate assets was 34.1%, and our ratio of gross debt to total market capitalization was 37.3%. These debt ratios are based on total principal amount outstanding for our various loans, including $120 million associated with one held-for-sale asset, 35 West Wacker Drive.

-  On September 13, 2011, Piedmont completed the purchase of 225 and 235 Presidential Way, a project consisting of two, five-story office buildings with a total of 440,000 square feet located in Woburn, MA, a suburb of Boston. The purchase price of the project was $85.3 million, or $194 per square foot. The buildings are well located along Interstate 93 within close proximity to the Route 128 / Interstate 95 intersection and were constructed in 2000 and 2001. The buildings are 100% leased to Raytheon Company, which has an S&P credit rating of A-, through 2019.

-  On July 1, 2011, the Company completed the sale of Eastpointe Corporate Center, a 156,000 square foot, five-story building located in Issaquah, WA, a suburb of Seattle, to an owner/occupant for approximately $32 million, or $205 per square foot. Piedmont recorded a $12.2 million gain upon the sale of the property. The operating income for the disposed asset is presented in discontinued operations. The building’s leased percentage dropped from 43% to 19% on the date of the sale due to the expiration of a lease. Through the sale, Piedmont was able to mitigate the leasing risk associated with this building and further its strategic objective of focusing on select markets, while simultaneously securing an attractive sale price for the property.

-  On August 31, 2011, Piedmont completed the sale of 5000 Corporate Court, a 264,000 square foot office building located in Holtsville, NY. The sale price of the building was $39.3 million, or $148 per square foot. Piedmont recorded a $14.6 million gain upon the sale of the property. The building is located on Long Island and is leased principally to the United States General Services Administration. The operating income for the disposed asset is presented in discontinued operations.

-  On August 25, 2011, Piedmont, along with its joint venture partners, sold 47300 Kato Road, a 58,000 square foot building in Fremont, CA to an owner/occupant. The gross sale price was $3.8 million, or $65 per square foot. Piedmont’s ownership in the property was approximately 78%. Piedmont recognized a $71,000 gain on the sale of its interest in the asset.

-  On August 1, 2011, Piedmont entered into an agreement to sell its 96.5% ownership interest in 35 West Wacker Drive, a 1,118,000 square foot office building in Chicago, IL. The agreed upon gross sale price values the building at $401.0 million, or $359 per square foot. The buyer completed its due diligence study of the asset on September 15, 2011, and its deposit of $15 million became non-refundable. The asset was reclassified from real estate assets held-for-use to real estate assets held-for-sale as of September 15, 2011. The operating income for the asset is presented in discontinued operations. The sale of the ownership interest is contingent upon lender approvals and is anticipated to close by year end.

-  On August 9, 2011, the Board of Directors of Piedmont declared dividends for the third quarter of 2011 in the amount of $0.315 per common share outstanding to stockholders of record as of the close of business on September 1, 2011. The dividends were paid on September 22, 2011.

-  The maturity dates for three loans (the two loans totaling $185 million in face value associated with 500 West Monroe Street and the $500 million line of credit facility) were extended during the third quarter of 2011. All three loans will now mature during the third quarter of 2012. Please see page 19 for additional details.

Subsequent Events                              

- On October 5, 2011, Piedmont entered into an agreement to purchase 400 TownPark, a 176,000 square foot, five-story office building in suburban Orlando, FL. As of that date, approximately 13% of the agreed upon purchase price of $23.9 million, or $136 per square foot, had been deposited into escrow and was non-refundable. The construction of the building was completed in 2008 with an efficient, LEED design. The building is currently 19% leased and is located within the amenity-rich, mixed-use development of TownPark, which is located adjacent to Interstate 4 in the Lake Mary suburb of Orlando. The building offers the only contiguous block of vacant space over 50,000 square feet in the market. The low cost basis and high-quality construction of the building should afford the Company a competitive advantage in securing a large corporate user as the economy recovers. The purchase of the building is anticipated to be completed during the fourth quarter of 2011.

- The Company has signed a new, 11-year lease for approximately 79,000 square feet with Synchronoss Technologies at 200 Bridgewater Crossing in Bridgewater, NJ. The lease is for space that is currently leased to Sanofi-aventis US. Piedmont is actively marketing for lease the remainder of the space occupied by the current tenant.

- On November 2, 2011, the Board of Directors of Piedmont declared dividends for the fourth quarter of 2011 in the amount of $0.315 per common share outstanding to stockholders of record as of the close of business on December 1, 2011. The dividends are expected to be paid on December 22, 2011.

- On November 2, 2011, the Board of Directors of Piedmont authorized the repurchase of up to$300 million of the Company’s common stock over the next two years. Any repurchases of shares of common stock will depend upon market conditions, as well as other factors, and such repurchases will be made at the discretion of the Company.

Guidance for 2011                               

- The Company is adjusting its financial guidance for calendar year 2011 to the upper end of its previously published range as follows:

	Low        High
Core Funds from Operations	$264   -  $269 million
Core Funds from Operations per diluted share	$1.53  -  $1.56

These estimates reflect management’s view of current market conditions and incorporate certain economic and operational assumptions and projections. 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 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 23 for additional leased percentage information.

⁽²⁾Impairment losses include losses for both wholly-owned and our proportionate share of unconsolidated joint venture assets.

⁽³⁾Core EBITDA, Core FFO and AFFO have been adjusted to exclude impairments on real estate assets as shown on pages 37 and 38.

⁽⁴⁾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. Amount includes $120 million of debt associated with one held-for-sale asset, 35 West Wacker Drive.

⁽⁵⁾Core EBITDA margin is calculated as Core EBITDA divided by total revenues (including revenues associated with discontinued operations).

⁽⁶⁾Fixed charge coverage 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.

⁽⁷⁾ The change in Piedmont’s debt coverage ratios in 2011 as compared to those for the year ended December 31, 2010, is primarily attributable to $185 million of debt associated with 500 West Monroe Street and the interest expense associated therewith.

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

The recapitalization had the effect of a one-for-three reverse stock split. All prior period per share data has been restated to give net effect to this one-for-three reverse stock split.

⁽¹⁾ Includes amounts attributable to wholly-owned properties, including discontinued operations, and our proportionate share of amounts attributable to unconsolidated joint ventures.

⁽²⁾Acquisitions consist of Suwanee Gateway One in Suwanee, GA, purchased on September 28, 2010, Meridian Crossings in Richfield, MN, purchased on October 1, 2010, 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, and 225 and 235 Presidential Way in Woburn, MA, purchased on September 13, 2011.

⁽³⁾Dispositions consist of 111 Sylvan Avenue in Englewood Cliffs, NJ, sold on December 8, 2010, Eastpointe Corporate Center in Issaquah, WA, sold on July 1, 2011 and 5000 Corporate Court in Holtsville, NY, sold on August 31, 2011.

⁽⁴⁾ Large contributors to the variance between the Same Store Net Operating Income for the three months ended September 30, 2011 and that for September 30, 2010 were one-time items such as the property tax accrual adjustments made in 2010 associated with successful appeals of Chicago property tax assessments. Excluding the impact of these one-time adjustments, the period over period change would have been -3.1%.

⁽⁵⁾ The decrease in Chicago Same Store Net Operating Income for the three months ended September 30, 2011 as compared to the same period in 2010 was primarily related to one-time adjustments to property tax accruals made in the third quarter of 2010 related to successful appeals of property tax assessments which resulted in lower property tax liabilities in 2010. This decrease in Chicago Same Store Net Operating Income for the three months ended September 30, 2011 was offset somewhat by increased rental income at Windy Point I in Schaumburg, IL due to a rental abatement concession in 2010 associated with a lease renewal.

⁽⁶⁾ The decrease in Washington, D.C. Same Store Net Operating Income for the three months and the nine months ended September 30, 2011 as compared to the same periods in 2010 was primarily related to a 46,000 square foot lease termination at the beginning of the first quarter of 2011 at 1201 Eye Street in Washington, D.C. as well as the expiration of a 41,000 square foot lease during the first quarter of 2011 at 11109 Sunset Hills Road in Reston, VA.

⁽⁷⁾ The increase in New York Same Store Net Operating Income for the three months and the nine months ended September 30, 2011 as compared to the same periods in 2010 was primarily related to rental rate increases at 60 Broad Street in New York, NY. An additional contributor to the increase in New York Same Store Net Operating Income for the nine months ended September 30, 2011 as compared to the same period in 2010 was a rental abatement concession that was provided in 2010 associated with the lease extension/restructure with the State of New York at 60 Broad Street in New York, NY.

⁽⁸⁾ The decrease in Minneapolis Same Store Net Operating Income for the three months and the nine months ended September 30, 2011 as compared to the same periods in 2010 was primarily related to an 80,000 square foot partial lease termination by US Bank during the second quarter of 2011 at US Bancorp Center in Minneapolis, MN.

⁽⁹⁾ The decrease in Los Angeles Same Store Net Operating Income for the three months and the nine months ended September 30, 2011 as compared to the same periods in 2010 was primarily due to a rental abatement concession in 2011 associated with a long-term lease renewal with Panasonic at 26200 Enterprise Way in Lake Forest, CA, and the expiration of a lease, resulting in a net decrease in leased square footage of 58,000 square feet, at 1055 East Colorado Boulevard in Pasadena, CA. An additional contributor to the decrease in Los Angeles Same Store Net Operating Income for the nine months ended September 30, 2011 as compared to the same period in 2010 was a space contraction associated with the Nestle lease renewal effective third quarter 2010 along with a roll down of total revenues per square foot received from that tenant at 800 North Brand Boulevard in Glendale, CA.

⁽¹⁰⁾ The decrease in Boston Same Store Net Operating Income for the three months and the nine months ended September 30, 2011 as compared to the same periods in 2010 was primarily due to a rental rate reduction and a rental abatement concession associated with a long-term lease renewal with State Street Bank at 1200 Crown Colony Drive in Quincy, MA.

⁽¹¹⁾ The decrease in Other Same Store Net Operating Income for the three months and the nine months ended September 30, 2011 as compared to the same periods in 2010 was due to a number of factors, the largest four of which were reduced rental rates achieved on new and renewal leases which commenced in late 2010 and early 2011 at 150 West Jefferson in Detroit, MI, a rental abatement concession in 2011 associated with a new lease with Chrysler Group, LLC and the related early termination of the previous lease at 1075 West Entrance in Auburn Hills, MI, a lease contraction of approximately 91,000 square feet effective third quarter 2010 at Chandler Forum in Chandler, AZ, and a rental abatement concession in 2011 associated with a new lease at Desert Canyon 300 in Phoenix, AZ.

Debt Analysis

As of September 30, 2011

Unaudited

Debt Covenant Compliance(1)	Required		Actual
Maximum Leverage Ratio		0.60		0.35
Minimum Fixed Charge Coverage Ratio (2)		1.50		4.90
Maximum Secured Indebtedness Ratio		0.40		0.28
Minimum Unencumbered Leverage Ratio		1.60		5.94
Minimum Unencumbered Interest Coverage Ratio(3)		1.75		23.18
Maximum Certain Permitted Investments Ratio(4)		0.35		0.01
(1) Debt covenant compliance calculations relate to specific calculations detailed in our line of credit agreement. (2) Defined as EBITDA for the trailing four quarters (including the company's share of EBITDA from unconsolidated interests), less one-time or non-recurring gains or losses, less a $0.15 per square foot capital reserve, and excluding the impact of straight line rent leveling adjustments and amortization of intangibles divided by the company's share of fixed charges, as more particularly described in the credit agreements. 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.

Other Debt Coverage Ratios(5)	Three months ended September 30, 2011	Nine months ended September 30, 2011	Year ended December 31,  2010
Net debt to core EBITDA	4.6 x	4.6 x	3.8 x
Fixed charge coverage ratio(6)	4.9 x	4.8 x	4.9 x
Interest coverage ratio(7)	4.9 x	4.8 x	4.9 x
(5) The change in Piedmont’s debt coverage ratios in 2011 as compared to those for the year ended December 31, 2010, is primarily attributable to the addition of $185 million of debt associated with 500 West Monroe Street. All ratios include amounts attributable to 35 West Wacker Drive. (6) 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 periods ended September 30, 2011 and December 31, 2010. (7) Interest coverage ratio is calculated as Core EBITDA divided by the sum of interest expense and capitalized interest. We had no capitalized interest during the periods ended September 30, 2011 and December 31, 2010.

(2) The classification of a tenant as “not rated” does not indicate that the tenant is of poor credit quality, but can indicate that the tenant or the tenant’s debt, if any, has not been rated. Included in this category are such tenants as Winston & Strawn, Independence Blue Cross, McKinsey & Company and KPMG.

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”.

(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 2011 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, DC. As of September 30, 2011, the total short-term space amounts to approximately 63,000 square feet and it will be occupied until an estimated date of June 30, 2013.

(4) Excluding executed but not commenced leases for currently vacant spaces, comprising approximately 371,000 square feet, Piedmont’s economic occupancy (including tenants in free rent periods) as of September 30, 2011 was 84.7%.

(5) 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.

⁽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. 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.

Annualized rental income associated with such new leases is removed from the expiry year of the current lease and added to the expiry year of the new lease. These adjustments effectively incorporate known roll ups and roll downs into the expiration schedule.

⁽²⁾ Leases and other revenue-producing agreements on a month-to-month basis, aggregating 31,094 square feet and Annualized Lease Revenue of $381,803, are assigned a lease expiration date of a year and a day beyond the period end date.

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. Capital expenditures have been restated for all prior periods in order to provide a consistent basis for comparison. Our revised definition of these measures can be found on pages 34 and 35.

⁽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 $75.0 million, or 52% of total outstanding commitments.

⁽²⁾ Of the total tenant improvement commitments outstanding, approximately $128 million will be classified as non-incremental capital expenditures when incurred. The total tenant improvement commitments outstanding includes $34.6 million related to one held-for-sale asset, 35 West Wacker Drive. If amounts attributable to 35 West Wacker Drive were excluded, total outstanding tenant improvement commitments as of September 30, 2011, would be $110.7 million, of which $92.3 million would be classified as non-incremental capital expenditures when incurred.

This assumption is made based upon the historical tenant improvement allowance usage patterns of the Company’s tenants.

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 37-39.

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 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 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 (“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; current adverse market and economic conditions; 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; the success of our real estate strategies and investment objectives; availability of financing; costs of complying with governmental laws and regulations; uncertainties associated with environmental and other regulatory matters; our ability to continue to qualify as a REIT under the Internal Revenue Code; the impact of outstanding or potential litigation; 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.
