COMPANY PROFILE

The Company

Boston Properties, Inc. (the “Company”), a self-administered and self-managed real estate investment trust (REIT), is one of the largest owners, managers, and developers of first-class office properties in the United States, with a significant presence in five markets: Boston, Washington, D.C., Midtown Manhattan, San Francisco, and Princeton, N.J. The Company was founded in 1970 by Mortimer B. Zuckerman and Edward H. Linde in Boston, where it maintains its headquarters. Boston Properties became a public company in June 1997. The Company acquires, develops, and manages its properties through full-service regional offices. Its property portfolio is comprised primarily of first-class office space, one hotel, two residential properties and three retail properties. Boston Properties is well-known for its in-house building management expertise and responsiveness to tenants’ needs. The Company holds a superior track record in developing premium Central Business District (CBD) office buildings, suburban office centers and build-to-suit projects for the U.S. government and a diverse array of creditworthy tenants.

Management

Boston Properties’ senior management team is among the most respected and accomplished in the REIT industry. Our deep and talented team of thirty-four individuals averages twenty-six years of real estate experience and sixteen years with Boston Properties. We believe that our size, management depth, financial strength, reputation, and relationships of key personnel provide a competitive advantage to realize growth through property development and acquisitions. Boston Properties benefits from the reputation and relationships of key personnel, including Mortimer B. Zuckerman, Chairman of the Board of Directors and Chief Executive Officer; Douglas T. Linde, President; E. Mitchell Norville, Executive Vice President and Chief Operating Officer; Raymond A. Ritchey, Executive Vice President and National Director of Acquisitions and Development; and Michael E. LaBelle, Chief Financial Officer. Our senior management team’s national reputation helps us attract business and investment opportunities. In addition, our other senior officers that serve as Regional Managers have strong reputations that assist in identifying and closing on new opportunities, having opportunities brought to us, and in negotiating with tenants and build-to-suit prospects. Additionally, Boston Properties’ Board of Directors consists of ten distinguished members, the majority of whom serve as Independent Directors.

Strategy

Boston Properties’ primary business objective is to maximize return on investment in an effort to provide its stockholders with the greatest possible total return. To achieve this objective, the Company maintains a consistent strategy that includes the following:

• concentrating on a few carefully selected markets characterized by high barriers to the creation of new supply and strong real estate fundamentals where tenants have demonstrated a preference for high-quality office buildings and other facilities;

• selectively acquiring assets which increase its penetration in these select markets;

• taking on complex, technically-challenging projects that leverage the skills of its management team to successfully develop, acquire, and reposition properties;

• exploring joint-venture opportunities with partners who seek to benefit from the Company’s depth of development and management expertise;

• pursuing the sale of properties (on a selective basis) to take advantage of its value creation and the demand for its premier properties; and

• continuing to enhance the Company’s balanced capital structure through its access to a variety of capital sources.

(1) Represents the remaining debt discount which will be amortized over the period during which the exchangeable senior notes are expected to be outstanding (i.e., through the first optional redemption dates or, in the case of the exchangeable senior notes due 2014, the maturity date) as additional non-cash interest expense.

(2) During the second quarter of 2010, the Company’s Operating Partnership repurchased approximately $132.8 million aggregate principal amount of its 2.875% exchangeable senior notes due 2037 for approximately $132.5 million. These repurchased notes had an aggregate carrying value of approximately $126.4 million, resulting in the recognition of a loss on extinguishment of approximately $6.1 million.

(3) The initial exchange rate is 8.5051 shares per $1,000 principal amount of the notes (or an initial exchange price of approximately $117.58 per share of Boston Properties, Inc.’s common stock). In addition, the Company entered into capped call transactions with affiliates of certain of the initial purchasers, which are intended to reduce the potential dilution upon future exchange of the notes. The capped call transactions are expected to have the effect of increasing the effective exchange price to the Company of the notes from $117.58 to approximately $137.17 per share (subject to adjustments), representing an overall effective premium of approximately 40% over the closing price on August 13, 2008 of $97.98 per share of Boston Properties, Inc.’s common stock. The net cost of the capped call transactions was approximately $44.4 million. As of June 30, 2010, the exchange price was $136.34 per share.

(4) Value based on June 30, 2010 closing price of $71.34 per share of common stock.

(5) Includes 119 shares of restricted stock.

(6) Includes 1,550 long-term incentive plan units, but excludes 1,081 unvested outperformance plan units.

Senior Unsecured Debt Covenant Compliance Ratios

(in thousands)

In the fourth quarter of 2002, the Company’s operating partnership (Boston Properties Limited Partnership) received investment grade ratings on its senior unsecured debt securities and thereafter issued unsecured notes. The notes were issued under an indenture, dated as of December 13, 2002, by and between Boston Properties Limited Partnership and The Bank of New York, as trustee, as supplemented, which, among other things, requires us to comply with the following limitations on incurrence of debt: Limitation on Outstanding Debt; Limitation on Secured Debt; Ratio of Annualized Consolidated EBITDA to Annualized Interest Expense; and Maintenance of Unencumbered Assets. Compliance with these restrictive covenants requires us to apply specialized terms the meanings of which are described in detail in our filings with the SEC, and to calculate ratios in the manner prescribed by the indenture.

This section presents such ratios as of June 30, 2010 to show that the Company’s operating partnership was in compliance with the terms of the indenture, as amended, which has been filed with the SEC. This section also presents certain other indenture-related data which we believe assists investors in the Company’s unsecured debt securities. Management is not presenting these ratios and the related calculations for any other purpose or for any other period, and is not intending for these measures to otherwise provide information to investors about the Company’s financial condition or results of operations. Investors should not rely on these measures other than for purposes of testing our compliance with the indenture.

Second Quarter 2010

Boston Properties Office Value-Added Fund, L.P.

On October 25, 2004, the Company formed Boston Properties Office Value-Added Fund, L.P. (the “Value-Added Fund”), a strategic partnership with third parties, to pursue the acquisition of value-added investments in non-core office assets within the Company’s existing markets. The Value-Added Fund had total equity commitments of $140 million. The Company receives asset management, property management, leasing and redevelopment fees and, if certain return thresholds are achieved, will be entitled to an additional promoted interest.

On January 7, 2008, the Company transferred the Mountain View properties to its Value-Added Fund. In connection with the transfer of the Research Park and Technology Park properties to the Value-Added Fund, the Company and its partners agreed to certain modifications to the Value-Added Fund’s original terms, including bifurcating the Value-Added Fund’s promote structure such that Research Park and Technology Park will be accounted for separately from the non-Mountain View properties currently owned by the Value-Added Fund (i.e., Circle Star and 300 Billerica Road). As a result of the modifications, the Company’s interest in the Mountain View properties is approximately 39.5% and its interest in the non-Mountain View properties is 25%. The Company does not expect that the Value-Added Fund will make any future investments in new properties. The investments held by the Value-Added Fund are not included in the Company’s portfolio information tables or any other portfolio level statistics and therefore are presented below.

Definitions

This section contains an explanation of certain non-GAAP financial measures we provide in other sections of this document, as well as the reasons why management believes these measures provide useful information to investors about the Company’s financial condition or results of operations. Additional detail can be found in the Company’s most recent annual report on Form 10-K and quarterly report on Form 10-Q, as well as other documents filed with or furnished to the SEC from time to time.

Funds from Operations

Pursuant to the revised definition of Funds from Operations adopted by the Board of Governors of the National Association of Real Estate Investment Trusts (“NAREIT”), we calculate Funds from Operations, or “FFO,” by adjusting net income (loss) attributable to Boston Properties, Inc. (computed in accordance with GAAP, including non-recurring items) for gains (or losses) from sales of properties, real estate related depreciation and amortization, and after adjustment for unconsolidated partnerships and joint ventures. FFO is a non-GAAP financial measure. The use of FFO, combined with the required primary GAAP presentations, has been fundamentally beneficial in improving the understanding of operating results of REITs among the investing public and making comparisons of REIT operating results more meaningful. Management generally considers FFO to be a useful measure for reviewing our comparative operating and financial performance because, by excluding gains and losses related to sales of previously depreciated operating real estate assets and excluding real estate asset depreciation and amortization (which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates), FFO can help one compare the operating performance of a company’s real estate between periods or as compared to different companies. Our computation of FFO may not be comparable to FFO reported by other REITs or real estate companies that do not define the term in accordance with the current NAREIT definition or that interpret the current NAREIT definition differently.

FFO should not be considered as an alternative to net income attributable to Boston Properties, Inc. (determined in accordance with GAAP) as an indication of our performance. FFO does not represent cash generated from operating activities determined in accordance with GAAP, and is not a measure of liquidity or an indicator of our ability to make cash distributions. We believe that to further understand our performance, FFO should be compared with our reported net income attributable to Boston Properties, Inc. and considered in addition to cash flows determined in accordance with GAAP, as presented in our consolidated financial statements.

Funds Available for Distribution (FAD)

In addition to FFO, we present Funds Available for Distribution (FAD) by (1) adding to FFO non-real estate depreciation, fair value interest adjustment, losses from early extinguishments of debt, impairments, ASC 470-20 (formerly known as FSP APB 14-1) interest expense adjustment, non-cash stock-based compensation expense, and partners’ share of joint venture 2nd generation tenant improvement and leasing commission, (2) eliminating the effects of straight-line rent and fair value lease revenue, (3) subtracting: recurring capital expenditures; hotel improvements, equipment upgrades and replacements; and second generation tenant improvement and leasing commissions (included in the period in which the lease commences); and (4) subtracting the gain from suspension of development, non-cash termination income and non-cash income from the termination of a management agreement. Although our FAD may not be comparable to that of other REITs and real estate companies, we believe it provides a meaningful indicator of our ability to fund cash needs and to make cash distributions to equity owners. In addition, we believe that to further understand our liquidity, FAD should be compared with our cash flows determined in accordance with GAAP, as presented in our consolidated financial statements. FAD does not represent cash generated from operating activities determined in accordance with GAAP, and FAD should not be considered as an alternative to net income (determined in accordance with GAAP) as an indication of our performance, as an alternative to net cash flows from operating activities (determined in accordance with GAAP), or as a measure of our liquidity.

Total consolidated debt to total consolidated market capitalization ratio, defined as total consolidated debt as a percentage of the market value of our outstanding equity securities plus our total consolidated debt, is a measure of leverage commonly used by analysts in the REIT sector. Total consolidated market capitalization is the sum of (A) our total consolidated indebtedness outstanding plus (B) the market value of our outstanding equity securities calculated using the closing price per share of common stock of the Company multiplied by the sum of (1) outstanding shares of common stock of the Company, (2) outstanding common units of limited partnership interest in Boston Properties Limited Partnership (excluding common units held by the Company), (3) common units issuable upon conversion of all outstanding Series Two Preferred Units of partnership interest in Boston Properties Limited Partnership and (4) common units issuable upon conversion of all outstanding LTIP Units, assuming all conditions have been met for the conversion of the LTIP Units. The calculation of total consolidated market capitalization does not include OPP Units because, unlike other LTIP Units, they are not earned until certain thresholds are achieved. We are presenting this ratio because our degree of leverage could affect our ability to obtain additional financing for working capital, capital expenditures, acquisitions, development or other general corporate purposes. Investors should understand that our total consolidated debt to total consolidated market capitalization ratio is in part a function of the market price of the common stock of the Company, and as such will fluctuate with changes in such price and does not necessarily reflect our capacity to incur additional debt to finance our activities or our ability to manage our existing debt obligations. However, for a company like ours, whose assets are primarily income-producing real estate, the total consolidated debt to total consolidated market capitalization ratio may provide investors with an alternate indication of leverage, so long as it is evaluated along with the ratio of indebtedness to other measures of asset value used by financial analysts and other financial ratios, as well as the various components of our outstanding indebtedness.

Total Combined Debt to Total Combined Market Capitalization Ratio

Total combined debt to total combined market capitalization ratio, defined as total combined debt (which equals our total consolidated debt plus our share of unconsolidated joint venture debt) as a percentage of the market value of our outstanding equity securities plus our total combined debt, is an alternative measure of leverage used by some analysts in the REIT sector. Total combined market capitalization is the sum of (A) our total combined debt plus (B) the market value of our outstanding equity securities calculated using the closing price per share of common stock of the Company multiplied by the sum of (1) outstanding shares of common stock of the Company, (2) outstanding common units of limited partnership interest in Boston Properties Limited Partnership (excluding common units held by the Company), (3) common units issuable upon conversion of all outstanding Series Two Preferred Units of partnership interest in Boston Properties Limited Partnership and (4) common units issuable upon conversion of all outstanding LTIP Units, assuming all conditions have been met for the conversion of the LTIP Units. The calculation of total combined market capitalization does not include OPP Units because, unlike other LTIP Units, they are not earned until certain thresholds are achieved.

We present this ratio because, following our acquisitions of the General Motors Building, Two Grand Central Tower, 125 West 55th Street and 540 Madison Avenue through unconsolidated joint ventures in June and August 2008, our share of unconsolidated joint venture debt increased significantly compared to prior periods when the amount of assets held through unconsolidated joint ventures was significantly smaller. In light of the difference between our total consolidated debt and our total combined debt, we believe that presenting our total combined debt to total combined market capitalization as well may provide investors with a more complete picture of our leverage. Investors should understand that our total combined debt to total combined market capitalization ratio is in part a function of the market price of the common stock of the Company, and as such will fluctuate with changes in such price and does not necessarily reflect our capacity to incur additional debt to finance our activities or our ability to manage our existing debt obligations. The total combined debt to total combined market capitalization ratio should be evaluated along with the ratio of indebtedness to other measures of asset value used by financial analysts and other financial ratios, as well as the various components of our outstanding indebtedness.

Consolidated Net Operating Income (NOI)

Consolidated NOI is a non-GAAP financial measure equal to net income attributable to Boston Properties, Inc., the most directly comparable GAAP financial measure, plus income attributable to noncontrolling interests, corporate general and administrative expense, depreciation and amortization, interest expense, losses from early extinguishments of debt and losses (gains) from investments in securities, less interest income, development and management services income, gain from suspension of development, gains from property dispositions, and income from unconsolidated joint ventures. In some cases we also present Consolidated NOI on a cash basis, which is Consolidated NOI after eliminating the effects of straight-lining of rent and fair value lease revenue. We use Consolidated NOI internally as a performance measure and believe Consolidated NOI provides useful information to investors regarding our financial condition and results of operations because it reflects only those income and expense items that are incurred at the property level. Therefore, we believe Consolidated NOI is a useful measure for evaluating the operating performance of our real estate assets. Our management also uses Consolidated NOI to evaluate regional property level performance and to make decisions about resource allocations. Further, we believe Consolidated NOI is useful to investors as a performance measure because, when compared across periods, Consolidated NOI reflects the impact on operations from trends in occupancy rates, rental rates, operating costs and acquisition and development activity on an unleveraged basis, providing perspective not immediately apparent from net income. Consolidated NOI excludes certain components from net income in order to provide results that are more closely related to a property’s results of operations. For example, interest expense is not necessarily linked to the operating performance of a real estate asset and is often incurred at the corporate level as opposed to the property level. In addition, depreciation and amortization, because of historical cost accounting and useful life estimates, may distort operating performance at the property level. Consolidated NOI presented by us may not be comparable to Consolidated NOI reported by other REITs that define Consolidated NOI differently. We believe that in order to facilitate a clear understanding of our operating results, Consolidated NOI should be examined in conjunction with net income as presented in our consolidated financial statements. Consolidated NOI should not be considered as an alternative to net income as an indication of our performance or to cash flows as a measure of our liquidity or ability to make distributions.

Combined Net Operating Income (NOI)

Combined NOI is a non-GAAP financial measure equal to Consolidated NOI plus our share of income from unconsolidated joint ventures. In some cases we also present Combined NOI on a cash basis, which is Combined NOI after eliminating the effects of straight-lining of rent and fair value lease revenue. In addition to Consolidated NOI, we use Combined NOI internally as a performance measure and believe Combined NOI provides useful information to investors regarding our financial condition and results of operations because it includes the impact of our unconsolidated joint ventures, which have become significant. Therefore, we believe Combined NOI is a useful measure for evaluating the operating performance of all of our real estate assets, including those held by our unconsolidated joint ventures. Our management also uses Combined NOI to evaluate regional property level performance and to make decisions about resource allocations. Further, like Consolidated NOI, we believe Combined NOI is useful to investors as a performance measure because, when compared across periods, Combined NOI reflects the impact on operations from trends in occupancy rates, rental rates, operating costs and acquisition and development activity on an unleveraged basis, providing perspective not immediately apparent from net income. Combined NOI presented by us may not be comparable to Combined NOI reported by other REITs that define Combined NOI differently. We believe that in order to facilitate a clear understanding of our operating results, Combined NOI should be examined in conjunction with net income as presented in our consolidated financial statements. Combined NOI should not be considered as an alternative to net income as an indication of our performance or to cash flows as a measure of our liquidity or ability to make distributions.

Portfolio Net Operating Income (NOI)

Portfolio NOI is a non-GAAP financial measure equal to Combined NOI less our share of income from the Value-Added Fund in recognition of the fact that we do not include non-core office properties held by the fund in the Company’s portfolio information tables or other portfolio level statistics because they have deficiencies in property characteristics which provide opportunity to create value. In some cases we also present Portfolio NOI on a cash basis, which is Portfolio NOI after eliminating the effects of straight-lining of rent and fair value lease revenue. In addition to Consolidated NOI and Combined NOI, we use Portfolio NOI internally as a performance measure and believe Portfolio NOI provides useful information to investors regarding our financial condition and results of operations because it includes the impact of our unconsolidated joint ventures, which have become significant, but excludes the impact of the Value-Added Fund. Therefore, we believe Portfolio NOI is a useful measure for evaluating the operating performance of our active portfolio, including both consolidated assets and those held by our unconsolidated joint ventures. Our management also uses Portfolio NOI to evaluate regional property level performance and to make decisions about resource allocations. Further, like Consolidated NOI and Combined NOI, we believe Portfolio NOI is useful to investors as a performance measure because, when compared across periods, Portfolio NOI reflects the impact on operations from trends in occupancy rates, rental rates, operating costs and acquisition and development activity on an unleveraged basis, providing perspective not immediately apparent from net income. Portfolio NOI presented by us may not be comparable to Portfolio NOI reported by other REITs that define Portfolio NOI differently. We believe that in order to facilitate a clear understanding of our operating results, Portfolio NOI should be examined in conjunction with net income as presented in our consolidated financial statements. Portfolio NOI should not be considered as an alternative to net income as an indication of our performance or to cash flows as a measure of our liquidity or ability to make distributions.

In-Service Properties

We treat a property as being “in-service” upon the earlier of (i) lease-up and completion of tenant improvements or (ii) one year after cessation of major construction activity under GAAP. The determination as to when a property should be treated as “in-service” involves a degree of judgment and is made by management based on the relevant facts and circumstances of the particular property. For portfolio operating and occupancy statistics we specify a single date for treating a property as “in-service” which is generally later than the date the property is placed in-service for GAAP. Under GAAP a property may be placed in service in stages as construction is completed and the property is held available for occupancy. In accordance with GAAP, when a portion of a property has been substantially completed and occupied or held available for occupancy, we cease capitalization on that portion, though we may not treat the property as being “in-service,” and continue to capitalize only those costs associated with the portion still under construction. In-service properties include properties held by our unconsolidated joint ventures (other than the Value-Added Fund).

Same Properties

In our analysis of NOI, particularly to make comparisons of NOI between periods meaningful, it is important to provide information for properties that were in-service and owned by us throughout each period presented. We refer to properties acquired or placed in-service prior to the beginning of the earliest period presented and owned by us through the end of the latest period presented as “Same Properties.” “Same Properties” therefore exclude properties placed in-service, acquired or repositioned after the beginning of the earliest period presented or disposed of prior to the end of the latest period presented. Accordingly, it takes at least one year and one quarter after a property is acquired or treated as “in-service” for that property to be included in “Same Properties.” Pages 20-22 indicate by footnote the “In-Service Properties” which are not included in “Same Properties.” “Same Properties NOI” includes our share of net operating income from unconsolidated joint ventures (other than the Value-Added Fund).

Annualized Revenue

Contractual rental obligations at the end of the reporting period, including contractual reimbursements, on an annualized cash basis.

Future Annualized Revenue

Contractual rental obligations at lease expiration, including current contractual reimbursements, on an annualized cash basis.

As of June 30, 2010, the Company’s portfolio consisted of 144 properties, comprised primarily of Class A office space, one hotel, two residential properties and three retail properties, aggregating approximately 37.8 million square feet, including four properties under construction totaling 1.6 million square feet. In addition, the Company has structured parking for vehicles containing approximately 12.8 million square feet. The overall percentage of leased space for the 139 properties in service as of June 30, 2010 was 93.0%.

Significant events during the second quarter included:

• On April 1, 2010, the Company acquired a 30% interest in a joint venture entity that owns 500 North Capitol Street, NW located in Washington, DC. 500 North Capitol Street is an approximately 176,000 net rentable square foot office property which is fully-leased to a single tenant through March 2011. On April 1, 2010, the unconsolidated joint venture entity refinanced at maturity the mortgage loan collateralized by the property totaling approximately $26.8 million. The new mortgage loan totaling $22.0 million bears interest at a variable rate equal to the greater of (1) the prime rate, as defined in the loan agreement, or (2) 5.75% per annum. The loan currently bears interest at 5.75% per annum and matures on March 31, 2013. The Company’s investment in the unconsolidated joint venture totaling approximately $1.9 million was financed with cash contributions to the venture totaling approximately $1.4 million and the issuance to the seller of 5,906 common units of limited partnership interest in the Company’s Operating Partnership. The unconsolidated joint venture currently expects that it will remove the property from service and redevelop the property following the expiration of the lease in March 2011.

• On April 9, 2010, an unconsolidated joint venture in which the Company has a 60% interest refinanced its mortgage loan collateralized by Two Grand Central Tower located in New York City. The previous mortgage loan totaling $190.0 million bore interest at a fixed rate of 5.10% per annum and was scheduled to mature on July 11, 2010. The new mortgage loan totaling $180.0 million bears interest at a fixed rate of 6.00% per annum and matures on April 10, 2015. In connection with the refinancing, the joint venture repaid $10.0 million of the previous mortgage loan utilizing cash contributions from the joint venture’s partners on a pro rata basis.

The aggregate net proceeds to the Operating Partnership, after deducting underwriter discounts and offering expenses, were approximately $693.5 million. The notes mature on November 15, 2020, unless earlier redeemed. On April 7, 2010, in connection with the offering, the Company entered into two treasury lock agreements to fix the 10-year treasury

rate at 3.873% per annum on notional amounts aggregating $350.0 million. The Company subsequently cash-settled the treasury lock agreements and received approximately $0.4 million, which amount will be recognized as a reduction to the Company’s interest expense over the term of the notes.

• On April 21, 2010, the Company announced that it had established an “at the market” (ATM) stock offering program through which it may sell from time to time up to an aggregate of $400 million of its common stock through sales agents over a three-year period.

• On May 5, 2010, the Company satisfied the requirements of its master lease agreement related to the 2006 sale of 280 Park Avenue in New York City, resulting in the recognition of the remaining deferred gain on sale of real estate totaling approximately $1.0 million.

• On May 11, 2010, the Company’s Operating Partnership exercised its option to extend the maturity date under its $1.0 billion unsecured revolving credit facility to August 3, 2011.

• On June 1, 2010, the Company placed in-service Weston Corporate Center, an approximately 356,000 net rentable square foot Class A office property located in Weston, Massachusetts. The property is 100% leased.

• On June 15, 2010, the Company used available cash to repay the mortgage loan collateralized by its Eight Cambridge Center property located in Cambridge, Massachusetts totaling approximately $22.6 million.

• On June 15, 2010, an unconsolidated joint venture in which the Company has a 50% interest repaid the mortgage loan collateralized by land parcels at its site at Eighth Avenue and 46th Street in New York City utilizing cash contributions from the joint venture’s partners on a pro rata basis.

• During the second quarter of 2010, the Company’s Operating Partnership repurchased approximately $132.8 million aggregate principal amount of its 2.875% exchangeable senior notes due 2037, which the holders may require the Operating Partnership to repurchase in February 2012, for approximately $132.5 million. The repurchased notes had an aggregate carrying value of approximately $126.4 million, resulting in the recognition of a non-cash loss on extinguishment of approximately $6.1 million.

(1) Pursuant to the revised definition of Funds from Operations adopted by the Board of Governors of the National Association of Real Estate Investment Trusts (“NAREIT”), we calculate Funds from Operations, or “FFO,” by adjusting net income (loss) attributable to Boston Properties, Inc. (computed in accordance with GAAP, including non-recurring items) for gains (or losses) from sales of properties, real estate related depreciation and amortization, and after adjustment for unconsolidated partnerships and joint ventures. FFO is a non-GAAP financial measure. The use of FFO, combined with the required primary GAAP presentations, has been fundamentally beneficial in improving the understanding of operating results of REITs among the investing public and making comparisons of REIT operating results more meaningful. Management generally considers FFO to be a useful measure for reviewing our comparative operating and financial performance because, by excluding gains and losses related to sales of previously depreciated operating real estate assets and excluding real estate asset depreciation and amortization (which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates), FFO can help one compare the operating performance of a company’s real estate between periods or as compared to different companies.

Our computation of FFO may not be comparable to FFO reported by other REITs or real estate companies that do not define the term in accordance with the current NAREIT definition or that interpret the current NAREIT definition differently.

FFO should not be considered as an alternative to net income attributable to Boston Properties, Inc. (determined in accordance with GAAP) as an indication of our performance. FFO does not represent cash generated from operating activities determined in accordance with GAAP, and is not a measure of liquidity or an indicator of our ability to make cash distributions. We believe that to further understand our performance, FFO should be compared with our reported net income attributable to Boston Properties, Inc. and considered in addition to cash flows in accordance with GAAP, as presented in our consolidated financial statements.

(2) Real estate depreciation and amortization consists of depreciation and amortization from the Consolidated Statements of Operations of $81,400, $87,005, $164,475 and $164,375, our share of unconsolidated joint venture real estate depreciation and amortization of $30,124, $33,798, $61,137 and $65,174, less corporate-related depreciation and amortization of $469, $444, $939 and $959 for the three months and six months ended June 30, 2010 and 2009, respectively.
