FORWARD-LOOKING STATEMENTS

This Presentation contains forward-looking statements within the meaning of the federal securities laws, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. We intend these forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 and are including this statement for purposes of complying with those safe harbor provisions, in each case, to the extent applicable. We caution investors that any such forward-looking statements are based on current beliefs or expectations of future events and on assumptions made by, and information currently available to, our management. When used, the words "anticipate," "believe," "budget," "estimate," "expect," "intend," "may," "might," "plan," "project," "should," "will" and similar expressions that do not relate solely to historical matters are intended to identify forward-looking statements. Such statements are subject to risks, uncertainties and assumptions and are not guarantees of future performance or occurrences, which may be affected by known and unknown risks, trends, uncertainties and factors that are, in some cases, beyond our control. Should one or more of these known or unknown risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those expressed or implied by the forward-looking statements. We caution you that, while forward-looking statements reflect our good-faith beliefs when we make them, they are not guarantees of future performance or occurrences and are impacted by actual events when they occur after we make such statements. Accordingly, investors should use caution in relying on forward-looking statements, which are based on results and trends at the time they are made, to anticipate future results or trends.

One of the most significant factors that may cause actual results to differ materially from those expressed or implied by the forward-looking statements is the ongoing impact of the global COVID-19 pandemic on the U.S. and global economies, which has impacted, and is likely to continue to impact, us and, directly or indirectly, many of the other important factors below and the risks described in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2019 and our subsequent filings under the Exchange Act.

Some of the risks and uncertainties that may cause our actual results, performance or achievements to differ materially from those expressed or implied by forward-looking statements include, among others, the following:

  • the risks and uncertainties related to the impact of the COVID-19 global pandemic, including the duration, scope and severity of the pandemic domestically and internationally; federal, state and local government actions or restrictive measures implemented in response to COVID-19, the effectiveness of such measures, as well as the effect of any relaxation of current restrictions, and the direct and indirect impact of such measures on our and our tenants' businesses, financial condition, results of operation, cash flows, liquidity and performance, and the U.S. and international economy and economic activity generally; whether new or existing actions and measures continue to result in increasing unemployment that impacts the ability of our residential tenants to generate sufficient income to pay, or make them unwilling to pay rent in a timely manner, in full or at all; the health, continued service and availability of our personnel, including our key personnel and property management teams; and the effectiveness or lack of effectiveness of governmental relief in providing assistance to individuals and large and small businesses, including our tenants, that have suffered significant adverse effects from COVID-19;
  • volatile or adverse global economic and political conditions, health crises and dislocations in the credit markets could adversely affect our access to cost- effective capital and have a resulting material adverse effect on our business opportunities, results of operations and financial condition;
  • general risks affecting the real estate industry (including, without limitation, the inability to enter into or renew leases, tenant space utilization, dependence on tenants' financial condition, and competition from other developers, owners and operators of real estate);

49

FORWARD-LOOKING STATEMENTS (continued)

  • failure to manage effectively our growth and expansion into new markets and sub-markets or to integrate acquisitions and developments successfully;
  • the ability of our joint venture partners to satisfy their obligations;
  • risks and uncertainties affecting property development and construction (including, without limitation, construction delays, increased construction costs, cost overruns, inability to obtain necessary permits, tenant accounting considerations that may result in negotiated lease provisions that limit a tenant's liability during construction, and public opposition to such activities);
  • risks associated with the availability and terms of financing and the use of debt to fund acquisitions and developments or refinance existing indebtedness, including the impact of higher interest rates on the cost and/or availability of financing;
  • risks associated with forward interest rate contracts and the effectiveness of such arrangements;
  • risks associated with downturns in the national and local economies, increases in interest rates, and volatility in the securities markets;
  • risks associated with actual or threatened terrorist attacks;
  • costs of compliance with the Americans with Disabilities Act and other similar laws;
  • potential liability for uninsured losses and environmental contamination;
  • risks associated with the physical effects of climate change;
  • risks associated with security breaches through cyber attacks, cyber intrusions or otherwise, as well as other significant disruptions of our information technology (IT) networks and related systems, which support our operations and our buildings;
  • risks associated with BXP's potential failure to qualify as a REIT under the Internal Revenue Code of 1986, as amended;
  • possible adverse changes in tax and environmental laws;
  • the impact of newly adopted accounting principles on our accounting policies and on period-to-period comparisons of financial results;
  • risks associated with possible state and local tax audits;
  • risks associated with our dependence on key personnel whose continued service is not guaranteed; and
  • the other risk factors identified in our most recently filed Annual Report on Form 10-K for the fiscal year ended December 31, 2019 or described herein, including those under the caption "Risk Factors."

50

FORWARD-LOOKING STATEMENTS (continued)

The risks set forth above are not exhaustive. Other sections of this report may include additional factors that could adversely affect our business and financial performance. Moreover, we operate in a very competitive and rapidly changing environment, particularly in light of the circumstances relating to COVID-19. New risk factors emerge from time to time and it is not possible for management to predict all risk factors, nor can we assess the impact of all risk factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results. Investors should also refer to our most recent Annual Reports on Form 10-K and our Quarterly Reports on Form 10-Q for future periods and Current Reports on Form 8-K as we file them with the SEC, and to other materials we may furnish to the public from time to time through Current Reports on Form 8-K or otherwise, for a discussion of risks and uncertainties that may cause actual results, performance or achievements to differ materially from those expressed or implied by forward-looking statements. We expressly disclaim any responsibility to update any forward-looking statements to reflect changes in underlying assumptions or factors, new information, future events, or otherwise, and you should not rely upon these forward-looking statements after the date of this Appendix.

DEFINITIONS OF NON-GAAP FINANCIAL MEASURES AND OTHER TERMS

This Appendix contains definitions of certain non-GAAP financial measures and other terms that the Company uses in this presentation and, where applicable, quantitative reconciliations of the differences between the non-GAAP financial measures and the most directly comparable GAAP financial measures, the reasons why management believes these non-GAAP financial measures provide useful information to investors about the Company's financial condition and results of operations and the other purposes for which management uses the measures. 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 the Company files or furnishes to the SEC from time to time.

The Company also presents "BXP's Share" of certain of these measures, which are non-GAAP financial measures that are calculated as the consolidated amount calculated in accordance with GAAP, plus the Company's share of the amount from the Company's unconsolidated joint ventures (calculated based upon the Company's percentage ownership interest and, in some cases, after priority allocations), minus the Company's partners' share of the amount from the Company's consolidated joint ventures (calculated based upon the partners' percentage ownership interests and, in some cases, after priority allocations, income allocation to private REIT shareholders and their share of fees due to the Company). Management believes that presenting "BXP's Share" of these measures provides useful information to investors regarding the Company's financial condition and/or results of operations because the Company has several significant joint ventures and in some cases, the Company exercises significant influence over, but does not control, the joint venture, in which case GAAP requires that the Company account for the joint venture entity using the equity method of accounting and the Company does not consolidate it for financial reporting purposes. In other cases, GAAP requires that the Company consolidate the venture even though the Company's partner(s) owns a significant percentage interest. As a result, management believes that presenting BXP Share of various financial measures in this manner can help investors better understand the Company's financial condition and/or results of operations after taking into account its true economic interest in these joint ventures. The Company cautions investors that the ownership percentages used in calculating "BXP's Share" of these measures may not completely and accurately depict all of the legal and economic implications of holding an interest in a consolidated or unconsolidated joint venture. For example, in addition to partners' interests in profits and capital, venture agreements vary in the allocation of rights regarding decision making (both routine and major decisions), distributions, transferability of interests, financing and guarantees, liquidations and other matters. As a result, presentations of "BXP's Share" of a financial measure should not be considered a substitute for, and should only be considered together with and as a supplement to, the Company's financial information presented in accordance with GAAP.

In addition, the Company presents certain of these measures on a "Annualized" basis, which means the measure for the applicable quarter is multiplied by four (4). Management believes that presenting "Annualized" measures allows investors to compare results of a particular quarter to the same measure for full years and thereby more easily assess trend data. However, the Company cautions investors that "Annualized" measures should not be considered a substitute for the measure calculated in accordance with GAAP and should only be considered together with and as a supplement to the Company's financial information prepared in accordance with GAAP.

52

DEFINITIONS OF NON-GAAP FINANCIAL MEASURES AND OTHER TERMS (continued)

Annualized Revenue

Annualized Revenue is defined as (1) revenue less termination income for the quarter ended September 30, 2020, multiplied by four (4), plus (2) termination income for the quarter ended September 30, 2020. The Company believes that termination income can distort the results for any given period because termination income generally represents multiple months or years of a tenant's rental obligations that are paid in a lump sum in connection with a negotiated early termination of the tenant's lease and thus does not reflect the core ongoing operating performance of the Company's properties. As a result, the Company believes that by presenting Annualized Revenue without annualizing termination income, investors may more easily compare quarterly revenue to revenue for full fiscal years, which can provide useful trend data. Annualized Revenue should not be considered a substitute for revenue in accordance with GAAP and should only be considered together with and as a supplement to the Company's financial information prepared in accordance with GAAP.

Annualized Rental Obligations

Annualized Rental Obligations is defined as monthly Rental Obligations, as of the last day of the reporting period, multiplied by twelve (12).

53

DEFINITIONS OF NON-GAAP FINANCIAL MEASURES AND OTHER TERMS (continued)

Debt to Market Capitalization Ratio

Consolidated Debt to Consolidated Market Capitalization Ratio is a measure of leverage commonly used by analysts in the REIT sector that equals the quotient of (A) the Company's Consolidated Debt divided by (B) the Company's Consolidated Market Capitalization, presented as a percentage. Consolidated Market Capitalization is the sum of (x) the Company's Consolidated Debt plus (y) the market value of the Company's outstanding equity securities calculated using the closing price per share of common stock of the Company, as reported by the New York Stock Exchange, 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 LTIP Units, assuming all conditions have been met for the conversion of the LTIP Units, (4) on and after February 6, 2015, which was the end of the performance period for 2012 OPP Units and thus the date earned, common units issuable upon conversion of 2012 OPP Units that were issued in the form of LTIP Units, (5) on and after February 4, 2016, which was the end of the performance period for 2013 MYLTIP Units and thus the date earned, common units issuable upon conversion of 2013 MYLTIP Units that were issued in the form of LTIP Units, (6) on and after February 3, 2017, which was the end of the performance period for 2014 MYLTIP Units and thus the date earned, common units issuable upon conversion of 2014 MYLTIP Units that were issued in the form of LTIP Units, (7) on and after February 4, 2018, which was the end of the performance period for 2015 MYLTIP Units and thus the date earned, common units issuable upon conversion of 2015 MYLTIP Units that were issued in the form of LTIP Units, (8) on and after February 9, 2019, which was the end of the performance period for 2016 MYLTIP Units and thus the date earned, common units issuable upon conversion of 2016 MYLTIP Units that were issued in the form of LTIP Units and (9) on and after February 6, 2020, which was the end of the performance period for 2017 MYLTIP Units and thus the date earned, common units issuable upon conversion of 2017 MYLTIP Units that were issued in the form of LTIP Units plus (z) outstanding shares of 5.25% Series B Cumulative Redeemable Preferred Stock multiplied by their fixed liquidation preference of $2,500 per share. The calculation of Consolidated Market Capitalization does not include LTIP Units issued in the form of MYLTIP Awards unless and until certain performance thresholds are achieved and they are earned. Because their three-year performance periods have not yet ended, 2018, 2019 and 2020 MYLTIP Units are not included.

The Company also presents BXP's Share of Market Capitalization, which is calculated in a similar manner, except that BXP's Share of Debt is utilized instead of the Company's Consolidated Debt in both the numerator and the denominator. The Company presents these ratios because its degree of leverage could affect its ability to obtain additional financing for working capital, capital expenditures, acquisitions, development or other general corporate purposes and because different investors and lenders consider one or both of these ratios. Investors should understand that these ratios are, 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 do not necessarily reflect the Company's capacity to incur additional debt to finance its activities or its ability to manage its existing debt obligations. However, for a company like Boston Properties, Inc., whose assets are primarily income-producing real estate, these ratios may provide investors with an alternate indication of leverage, so long as they are 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 the Company's outstanding indebtedness.

EBITDAre

Pursuant to the definition of Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate adopted by the Board of Governors of the National Association of Real Estate Investment Trusts ("Nareit"), the Company calculates Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate, or "EBITDAre," as net income (loss) attributable to Boston Properties, Inc. common shareholders, the most directly comparable GAAP financial measure, plus net income attributable to noncontrolling interests, interest expense, losses (gains) from early extinguishments of debt, depreciation and amortization expense, impairment loss and adjustments to reflect the Company's share of EBITDAre from unconsolidated joint ventures, less gains (losses) on sales of real estate, gain on sale of investment in unconsolidated joint venture, gains on consolidation of joint ventures and discontinued operations. EBITDAre is a non-GAAP financial measure. The Company uses EBITDAre internally as a performance measure and believes EBITDAre provides useful information to investors regarding its financial condition and results of operations at the corporate level because, when compared across periods, EBITDAre reflects the impact on operations from trends in occupancy rates, rental rates, operating costs, general and administrative expenses and acquisition and development activities on an unleveraged basis, providing perspective not immediately apparent from net (loss) income attributable to Boston Properties, Inc. common shareholders.

In some cases the Company also presents (A) BXP's Share of EBITDAre - cash, which is BXP's Share of EBITDAre after eliminating the effects of straight-line rent (excluding the impact related to deferred revenue related to improvements to long-lived assets paid for by a tenant), fair value lease revenue and non-cash termination income adjustment (fair value lease amounts) and adding straight-line ground rent expense, stock-based compensation expense and lease transaction costs that qualify as rent inducements, and (B) Annualized EBITDAre, which is EBITDAre for the applicable fiscal quarter ended multiplied by four (4). Presenting BXP's Share of EBITDAre - cash allows investors to compare EBITDAre across periods without taking into account the effect of certain non-cash rental revenues, ground rent expense and stock based compensation expense. Similar to depreciation and amortization, because of historical cost accounting, fair value lease revenue may distort operating performance measures at the property level. Additionally, presenting EBITDAre excluding the impact of straight-line rent provides investors with an alternative view of operating performance at the property level that more closely reflects rental revenue generated at the property level without regard to future contractual increases in rental rates. In addition, the Company's management believes that the presentation of Annualized EBITDAre provides useful information to investors regarding the Company's results of operations because it enables investors to more easily compare quarterly EBITDAre to EBITDAre from full fiscal years.

The Company's computation of EBITDAre may not be comparable to EBITDAre 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. The Company believes that in order to facilitate a clear understanding of its operating results, EBITDAre should be examined in conjunction with net income attributable to Boston Properties, Inc. common shareholders as presented in the Company's consolidated financial statements. EBITDAre should not be considered a substitute to net income attributable to Boston Properties, Inc. common shareholders in accordance with GAAP or any other GAAP financial measures and should only be considered together with and as a supplement to the Company's financial information prepared in accordance with GAAP.

55

DEFINITIONS OF NON-GAAP FINANCIAL MEASURES AND OTHER TERMS (continued)

Fixed Charge Coverage Ratio

Fixed Charge Coverage Ratio equals BXP's Share of EBITDAre - cash divided by Total Fixed Charges. BXP's Share of EBITDAre - cash is a non- GAAP financial measure equal to BXP's Share of EBITDAre after eliminating the effects of straight-line rent (excluding the impact related to deferred revenue related to improvements to long-lived assets paid for by a tenant), fair value lease revenue and non-cash termination income adjustment (fair value lease amounts) and adding straight-line ground rent expense, stock-based compensation expense and lease transaction costs that qualify as rent inducements.

Total Fixed Charges is also a non-GAAP financial measure equal to the sum of BXP's Share of interest expense, capitalized interest, maintenance capital expenditures, hotel improvements, equipment upgrades and replacements and preferred dividends/distributions less fair value interest adjustment and hedge amortization and amortization of financing costs. The Company believes that the presentation of its Fixed Charge Coverage Ratio provides investors with useful information about the Company's financial performance as it relates to overall financial flexibility and balance sheet management, and, although the Company's Fixed Charge Coverage Ratio is not a liquidity measure, as it does not include adjustments to reflect changes in working capital or the actual timing of the payment of income or expense items that are accrued in the period, the Company believes that its Fixed Charge Coverage Ratio provides investors with useful supplemental information regarding the Company's ability to service its existing fixed charges. Furthermore, the Company believes that the Fixed Charge Coverage Ratio is frequently used by analysts, rating agencies and other interested parties in the evaluation of the Company's performance as a REIT and, as a result, by presenting the Fixed Charge Coverage Ratio the Company assists these parties in their evaluations. The Company's calculation of its Fixed Charge Coverage Ratio may not be comparable to the ratios reported by other REITs or real estate companies that define the term differently and should only be considered together with and as a supplement to the Company's financial information prepared in accordance with GAAP. For clarification purposes, this ratio does not include gains (losses) from early extinguishments of debt.

FORWARD-LOOKING STATEMENTS

Funds Available for Distribution (FAD) and FAD Payout Ratio

In addition to Funds from Operations (FFO), which is defined on the following page, the Company presents Funds Available for Distribution to common shareholders and common unitholders (FAD), which is a non-GAAP financial measure that is calculated by (1) adding to FFO lease transaction costs that qualify as rent inducements, non-real estate depreciation, non-cash losses (gains) from early extinguishments of debt, stock-based compensation expense, Accounting Standards Codification ("ASC") 470-20 interest expense adjustment, partners' share of consolidated and unconsolidated joint venture 2nd generation tenant improvement and leasing commissions (included in the period in which the lease commences) and unearned portion of capitalized fees, (2) eliminating the effects of straight-line rent, straight-line ground rent expense adjustment, fair value interest adjustment and hedge amortization and fair value lease revenue, and (3) subtracting maintenance capital expenditures, hotel improvements, equipment upgrades and replacements, 2nd generation tenant improvement and leasing commissions (included in the period in which the lease commences), non-cash termination income adjustment (fair value lease amounts) and impairments of non-depreciable real estate. The Company believes that the presentation of FAD provides useful information to investors regarding the Company's results of operations because FAD provides supplemental information regarding the Company's operating performance that would not otherwise be available and may be useful to investors in assessing the Company's operating performance. Additionally, although the Company does not consider FAD to be a liquidity measure, as it does not make adjustments to reflect changes in working capital or the actual timing of the payment of income or expense items that are accrued in the period, the Company believes that FAD may provide investors with useful supplemental information regarding the Company's ability to generate cash from its operating performance and the impact of the Company's operating performance on its ability to make distributions to its shareholders. Furthermore, the Company believes that FAD is frequently used by analysts, investors and other interested parties in the evaluation of its performance as a REIT and, as a result, by presenting FAD the Company is assisting these parties in their evaluation. FAD should not be considered as a substitute for net income (loss) attributable to Boston Properties, Inc.'s common shareholders determined in accordance with GAAP or any other GAAP financial measures and should only be considered together with and as a supplement to the Company's financial information prepared in accordance with GAAP.

FAD Payout Ratio is defined as distributions to common shareholders and unitholders (excluding any special distributions) divided by FAD.

57

DEFINITIONS OF NON-GAAP FINANCIAL MEASURES AND OTHER TERMS (continued)

Funds from Operations (FFO)

Pursuant to the revised definition of Funds from Operations adopted by the Board of Governors of Nareit, the Company calculates Funds from Operations, or "FFO," by adjusting net income (loss) attributable to Boston Properties, Inc. common shareholders (computed in accordance with GAAP) for gains (or losses) from sales of properties, impairment losses on depreciable real estate consolidated on the Company's balance sheet, impairment losses on its investments in unconsolidated joint ventures driven by a measurable decrease in the fair value of depreciable real estate held by the unconsolidated joint ventures and real estate-related depreciation and amortization. FFO is a non-GAAP financial measure, but the Company believes the presentation of FFO, combined with the presentation of required GAAP financial measures, has improved the understanding of operating results of REITs among the investing public and has helped make comparisons of REIT operating results more meaningful. Management generally considers FFO and FFO per share to be useful measures for understanding and comparing the Company's operating results because, by excluding gains and losses related to sales of previously depreciated operating real estate assets, impairment losses and real estate asset depreciation and amortization (which can differ across owners of similar assets in similar condition based on historical cost accounting and useful life estimates), FFO and FFO per share can help investors compare the operating performance of a company's real estate across reporting periods and to the operating performance of other companies.

The Company's 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. In order to facilitate a clear understanding of the Company's operating results, FFO should be examined in conjunction with net income attributable to Boston Properties, Inc. common shareholders as presented in the Company's consolidated financial statements. FFO should not be considered as a substitute for net income attributable to Boston Properties, Inc. common shareholders (determined in accordance with GAAP) or any other GAAP financial measures and should only be considered together with and as a supplement to the Company's financial information prepared in accordance with GAAP.

In-Service Properties

The Company treats a property as being "in-service" upon the earlier of (1) lease-up and completion of tenant improvements or (2) one year after cessation of major construction activity as determined under GAAP. The determination as to when an entire 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, the Company specifies a single date for treating a property as "in-service," which is generally later than the date the property is partially placed in-service under 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 addition, under GAAP, when a portion of a property has been substantially completed and either occupied or held available for occupancy, the Company ceases capitalizing costs on that portion, even though it may not treat the property as being "in-service," and continues to capitalize only those costs associated with the portion still under construction. In-service properties include properties held by the Company's unconsolidated joint ventures.

58

DEFINITIONS OF NON-GAAP FINANCIAL MEASURES AND OTHER TERMS (continued)

Net Debt

Net Debt is equal to (A) the Company's consolidated debt plus special dividends payable (if any) less (B) cash and cash equivalents and cash held in escrow for potential Section 1031 like kind exchange(s). The Company believes that the presentation of Net Debt provides useful information to investors because the Company reviews Net Debt as part of the management of its overall financial flexibility, capital structure and leverage. In particular, Net Debt is an important component of the Company's ratio of BXP's Share of Net Debt to BXP's Share of EBITDAre. BXP's Share of Net Debt is calculated in a similar manner to Net Debt, except that BXP's Share of Debt and BXP's Share of cash are utilized instead of the Company's consolidated debt and cash in the calculation. The Company believes BXP's Share of Net Debt to BXP's Share of EBITDAre is useful to investors because it provides an alternative measure of the Company's financial flexibility, capital structure and leverage based on its percentage ownership interest in all of its assets. Furthermore, certain debt rating agencies, creditors and credit analysts monitor the Company's Net Debt as part of their assessments of its business. The Company may utilize a considerable portion of its cash and cash equivalents at any given time for purposes other than debt reduction. In addition, cash and cash equivalents and cash held in escrow for potential Section 1031 like kind exchange(s) may not be solely controlled by the Company. The deduction of these items from consolidated debt in the calculation of Net Debt therefore should not be understood to mean that these items are available exclusively for debt reduction at any given time.

Net Operating Income (NOI)

Net operating income (NOI) is a non-GAAP financial measure equal to net income attributable to Boston Properties, Inc. common shareholders, the most directly comparable GAAP financial measure, plus (1) preferred dividends, net income attributable to noncontrolling interests, corporate general and administrative expense, payroll and related costs from management services contracts, transaction costs, impairment losses, depreciation and amortization expense, gains (losses) from early extinguishments of debt and interest expense, less (2) development and management services revenue, direct reimbursements of payroll and related costs from management services contracts, income (loss) from unconsolidated joint ventures, gains (losses) on sales of real estate, gains (losses) from investments in securities and interest and other income (loss). In some cases, the Company also presents (1) NOI - cash, which is NOI after eliminating the effects of straight-line rent (excluding the impact related to deferred revenue related to improvements to long-lived assets paid for by a tenant), fair value lease revenue, straight-line ground rent expense adjustment and lease transaction costs that qualify as rent inducements in accordance with GAAP, and (2) NOI and NOI - cash, in each case excluding termination income. (continued on next page)

59

DEFINITIONS OF NON-GAAP FINANCIAL MEASURES AND OTHER TERMS (continued)

Net Operating Income (NOI) (continued)

The Company uses these measures internally as performance measures and believes they provide useful information to investors regarding the Company's results of operations and financial condition because, when compared across periods, they reflect 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. 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. Similarly, interest expense may be incurred at the property level even though the financing proceeds may be used at the corporate level (e.g., used for other investment activity). In addition, depreciation and amortization expense because of historical cost accounting and useful life estimates, may distort operating performance measures at the property level. Presenting NOI - cash allows investors to compare NOI performance across periods without taking into account the effect of certain non-cash rental revenues and ground rent expenses. Similar to depreciation and amortization expense, fair value lease revenues, because of historical cost accounting, may distort operating performance measures at the property level. Additionally, presenting NOI excluding the impact of the straight-lining of rent provides investors with an alternative view of operating performance at the property level that more closely reflects net cash generated at the property level on an unleveraged basis. Presenting NOI measures that exclude termination income provides investors with additional information regarding operating performance at a property level that allows them to compare operating performance between periods without taking into account termination income, which can distort the results for any given period because they generally represent multiple months or years of a tenant's rental obligations that are paid in a lump sum in connection with a negotiated early termination of the tenant's lease and are not reflective of the core ongoing operating performance of the Company's properties.

Rental Obligations

Rental Obligations is defined as the contractual base rents (but excluding percentage rent) and budgeted reimbursements from tenants under existing leases. These amounts exclude rent abatements.

Rental Revenue

Rental Revenue is equal to Total revenue, the most directly comparable GAAP financial measure, less development and management services revenue and direct reimbursements of payroll and related costs from management services contracts. The Company uses Rental Revenue internally as a performance measure and in calculating other non-GAAP financial measures (e.g., NOI), which provides investors with information regarding our performance that is not immediately apparent from the comparable non-GAAP measures and allows investors to compare operating performance between periods. The Company also presents Rental Revenue (excluding termination income) because termination income can distort the results for any given period because it generally represents multiple months or years of a tenant's rental obligations that are paid in a lump sum in connection with a

negotiated early termination of the tenant's lease and does not reflect the core ongoing operating performance of the Company's properties.

Same Properties

In the Company's 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 the Company throughout each period presented. The Company refers to properties acquired or placed in- service prior to the beginning of the earliest period presented and owned by the Company through the end of the latest period presented as "Same Properties." "Same Properties" therefore exclude properties placed in-service, acquired, repositioned or in development or redevelopment 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."
