BOSTON PROPERTIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization

Boston Properties, Inc. (the “Company”), a Delaware corporation, is a self-administered and self-managed real estate investment trust (“REIT”). The Company is the sole general partner of Boston Properties Limited Partnership (the “Operating Partnership”) and at September 30, 2004 owned an approximate 80.0% (76.8% at September 30, 2003) general and limited partnership interest in the Operating Partnership. Partnership interests in the Operating Partnership are denominated as “common units of partnership interest” (also referred to as “OP Units”), “long term incentive units of partnership interest” (also referred to as “LTIP Units”) or “preferred units of partnership interest” (also referred to as “Preferred Units”).

Unless specifically noted otherwise, all references to OP Units exclude such units held by the Company. A holder of an OP Unit may present such OP Unit to the Operating Partnership for redemption at any time (subject to restrictions agreed upon at the time of issuance of OP Units to particular holders that may restrict such right for a period of time, generally one year from issuance). Upon presentation of an OP Unit for redemption, the Operating Partnership must redeem such OP Unit for cash equal to the then value of a share of common stock of the Company (“Common Stock”). In lieu of a cash redemption, the Company may elect to acquire such OP Unit for one share of Common Stock. Because the number of shares of Common Stock outstanding at all times equals the number of OP Units that the Company owns, one share of Common Stock is generally the economic equivalent of one OP Unit, and the quarterly distribution that may be paid to the holder of an OP Unit equals the quarterly dividend that may be paid to the holder of a share of Common Stock. An LTIP Unit is generally the economic equivalent of a share of restricted common stock of the Company. LTIP Units, whether vested or not, will receive the same quarterly per unit distributions as OP Units, which equal per share dividends on Common Stock (See Note 12).

Each series of Preferred Units bears a distribution that is set in accordance with an amendment to the partnership agreement of the Operating Partnership. Preferred Units may also be converted into OP Units at the election of the holder thereof or the Operating Partnership in accordance with the terms of the series of outstanding Preferred Units. At September 30, 2004, there was one series of Preferred Units outstanding.

All references to the Company refer to Boston Properties, Inc. and its consolidated subsidiaries, including the Operating Partnership, collectively, unless the context otherwise requires.

The Properties:

At September 30, 2004, the Company owned or had interests in a portfolio of 126 commercial real estate properties (140 and 139 properties at December 31, 2003 and September 30, 2003, respectively) (the “Properties”) aggregating approximately 44.2 million net rentable square feet (approximately 43.9 million and 43.5 million net rentable square feet at December 31, 2003 and September 30, 2003, respectively), including three properties under construction and one redevelopment/expansion project collectively totaling approximately 1.3 million net rentable square feet. During the three months ended September 30, 2004, the Company sold one Class A office property and one office/technical property aggregating approximately 93,000 net rentable square feet. In addition, the Company placed in-service two Class A office properties totaling 1.5 million net rentable square feet and commenced development on two Class A office properties and one redevelopment/expansion project totaling 0.7 million net rentable square feet. At September 30, 2004, the Properties consist of:

• 119 office properties comprised of 102 Class A office properties (including three properties under construction) and 17 office/technical properties;

• two industrial properties;

6

BOSTON PROPERTIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

• three hotels; and

• two retail properties.

In addition, the Company owns or controls land parcels totaling approximately 542.8 acres and structured parking for approximately 31,270 vehicles containing approximately 9.5 million square feet. The Company considers Class A office properties to be centrally located buildings that are professionally managed and maintained, that attract high-quality tenants and command upper-tier rental rates, and that are modern structures or have been modernized to compete with newer buildings. The Company considers office/technical properties to be properties that support office, research and development and other technical uses.

2. Basis of Presentation and Summary of Significant Accounting Policies

Boston Properties, Inc. does not have any other significant assets, liabilities or operations, other than its investment in the Operating Partnership, nor does it have employees of its own. The Operating Partnership, not Boston Properties, Inc., executes all significant business relationships. All majority-owned subsidiaries and affiliates over which the Company has financial and operating control and variable interest entities (“VIE”s) in which the Company has determined it is the primary beneficiary are included in the consolidated financial statements. All significant intercompany balances and transactions have been eliminated in consolidation. The Company accounts for all other unconsolidated joint ventures using the equity method of accounting. Accordingly, the Company’s share of the earnings of these joint ventures and companies is included in consolidated net income.

In January 2003, the Financial Accounting Standards Board (“FASB”) issued FASB Interpretation No. 46, “Consolidation of Variable Interest Entities” (“FIN 46”). In December 2003, the FASB issued FIN 46R, “Consolidation of Variable Interest Entities,” which amended FIN 46. FIN 46R was effective immediately for arrangements entered into after January 31, 2003, and became effective during the first quarter of 2004 for all arrangements entered into before February 1, 2003. FIN 46R requires existing unconsolidated VIEs to be consolidated by their primary beneficiaries. The primary beneficiary of a VIE is the party that absorbs a majority of the entity’s expected losses or receives a majority of its expected residual returns, or both, as a result of holding variable interests, which are the ownership interests, contractual interests, or other pecuniary interests in an entity that change with changes in the fair value of the entity’s net assets excluding variable interests. Prior to FIN 46R, the Company included an entity in its consolidated financial statements only if it controlled the entity through voting interests. The adoption and application of FIN 46 and FIN 46R has not had a material impact on the Company’s consolidated financial statements.

The accompanying interim financial statements are unaudited; however, the financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and in conjunction with the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the disclosures required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments (consisting solely of normal recurring matters) necessary for a fair presentation of the financial statements for these interim periods have been included. The results of operations for the interim periods are not necessarily indicative of the results to be obtained for other interim periods or for the full fiscal year. These financial statements should be read in conjunction with the Company’s financial statements and notes thereto contained in the Company’s annual report on Form 10-K for its fiscal year ended December 31, 2003, as revised on Form 8-K filed on June 8, 2004.

Summary of Significant Accounting Policies

Stock-based employee compensation plan

At September 30, 2004, the Company has stock-based employee compensation plans. In 2003, the Company transitioned to granting restricted stock and/or LTIP Units, as opposed to granting stock options, as its primary vehicle for employee equity compensation under its stock-based employee compensation plan. The Company accounts for its stock-based employee compensation plans under the recognition and measurement principles of the Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees,” and related interpretations. All outstanding options had an exercise price equal to the market value of the underlying common stock on the date of grant. The following table illustrates the effect on net income available to common shareholders and earnings per common share if the Company had applied the fair value recognition provisions of Statement of Financial Accounting Standards (“SFAS”) No. 123, “Accounting for Stock-Based Compensation,” to stock-based employee compensation.

3. Real Estate Activity During the Nine Months Ended September 30, 2004

Acquisitions

On March 24, 2004, the Company acquired the remaining outside interest (approximately 75%) in its 140 Kendrick Street joint venture, consisting of three Class A office properties totaling 380,987 square feet located in Needham, Massachusetts. The Company acquired the remaining interest for $21.6 million of cash and the assumption of the mortgage debt on the properties. This interest was previously accounted for as an investment in an unconsolidated joint venture.

On April 1, 2004, the Company acquired 1330 Connecticut Avenue, a 259,000 square foot Class A office property in Washington, D.C., at a purchase price of $86.6 million. In addition, the Company paid $1.4 million of closing costs and will be obligated to fund $9.2 million for tenant and capital improvements during the first two

years of ownership. The acquisition was financed with the assumption of mortgage indebtedness collateralized by the property totaling $52.4 million (which bears interest at a fixed rate of 7.58% per annum and matures in 2011) and proceeds from the Company’s March 2004 public offering of Common Stock.

See Item 2 – “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies” for a discussion of the Company’s policy for allocating purchase price to acquired assets and assumed liabilities.

Development

During the nine months ended September 30, 2004, the Company placed in-service its Times Square Tower development project. Times Square Tower is a 1,234,000 net rentable square foot Class A office tower located in Times Square, New York City. At September 30, 2004, the property was 81% leased.

5. Mortgage Notes Payable

On January 23, 2004, the Company refinanced its $493.5 million construction loan facility collateralized by the Times Square Tower property in New York City. The old construction loan facility bore interest at LIBOR + 1.95% per annum and was scheduled to mature in November 2004. The refinanced construction loan facility totals $475.0 million and is comprised of two tranches. The first tranche of the refinanced construction loan facility consists of a $300.0 million loan commitment which bears interest at LIBOR + 0.90% per annum and matures in January 2006. The first tranche includes a provision for a one-year extension at the option of the Company. The second tranche consists of a $175.0 million term loan which bears interest at LIBOR + 1.00% per annum and matures in January 2007. At September 30, 2004, the outstanding balance under the refinanced construction loan facility was $415.6 million. This loan facility involves a syndicate of lenders. Accordingly, for those lenders that participated in both the original loan and the refinancing, the initial direct debt issuance costs and the costs incurred with the refinancing are being amortized over the term of the loan. Furthermore, for those lenders that did not participate in the refinancing, the Company has reflected these amounts as an extinguishment, which did not have a significant impact on the Company’s consolidated financial statements.

On March 1, 2004, the Company repaid the mortgage loan collateralized by its One and Two Reston Overlook properties totaling approximately $65.8 million, together with a prepayment penalty totaling approximately $0.7 million. The mortgage loan bore interest at a fixed rate of 7.45% per annum and was scheduled to mature in August 2004.

On March 10, 2004, the Company repaid the mortgage loans collateralized by its Lockheed Martin and NIMA properties totaling approximately $24.5 million and $20.0 million, respectively, together with prepayment penalties aggregating approximately $5.6 million. The mortgage loans bore interest at fixed rates of 6.61% and 6.51% per annum, respectively, and were scheduled to mature in June 2008.

In connection with the acquisition of the remaining outside interest in 140 Kendrick Street in Needham, Massachusetts on March 24, 2004, the Company assumed the outside partner’s share of the mortgage loan collateralized by the properties of approximately $41.6 million. Immediately following the acquisition, 140 Kendrick Street had total outstanding mortgage debt of $55.5 million. Pursuant to the provisions of SFAS No. 141 “Business Combinations” (“SFAS No. 141”), the assumed mortgage debt bearing contractual interest at a fixed rate of 7.51% per annum was recorded at its fair value of approximately $62.1 million using an effective interest rate of 5.2% per annum.

BOSTON PROPERTIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

In connection with the acquisition of 1330 Connecticut Avenue in Washington, D.C. on April 1, 2004, the Company assumed the mortgage loan collateralized by the property of approximately $52.4 million. Pursuant to the provisions of SFAS No. 141, the assumed mortgage debt bearing contractual interest at a fixed rate of 7.58% per annum and maturing in February 2011 was recorded at its fair value of approximately $61.0 million using an effective interest rate of 4.65% per annum.

On September 24, 2004, the Company refinanced the construction loan on its New Dominion Technology Park, Building Two property located in Herndon, Virginia. The original construction loan with an outstanding balance of $56.9 million bore interest at LIBOR + 1.25% and was scheduled to mature in December 2005. The new mortgage loan totaling $63.0 million requires interest-only payments at a fixed rate of 5.55% per annum until it matures in October 2014. The Company has accounted for the refinancing as an extinguishment of debt, which did not have a significant impact on the Company’s consolidated financial statements.

6. Commitments and Contingencies

General

In the normal course of business, the Company guarantees its performance of services or indemnifies third parties against its negligence.

The Company has letter of credit and performance obligations of approximately $19.5 million related to lender and development requirements.

The Company, with its other third-party joint venture partners, has agreed to guarantee the seller financing totaling $23.5 million on behalf of its WP Project Developer LLC joint venture entity.

In addition, the Company and one of its joint venture partners have agreed to guarantee up to $7.5 million and $22.5 million, respectively, of a construction loan on behalf of a joint venture entity. The amounts guaranteed are subject to decrease (and elimination) upon the satisfaction of certain operating performance and financial measures. In the event the guarantee of the Company’s partner is unenforceable, the Company has agreed to satisfy such partner’s guarantee obligations. The Company’s partner has agreed to reimburse the Company for any amounts the Company pays in satisfaction of its partner’s guarantee obligations.

Certain of the Company’s joint venture agreements include provisions whereby, at certain specified times, each partner has the right to initiate a purchase or sale of its interest in the joint ventures. Under these provisions, the Company is not compelled to purchase the interest of its outside joint venture partners.

Development

The Company has four properties under construction and one redevelopment project as of September 30, 2004. Commitments to complete these projects totaled approximately $331.3 million at September 30, 2004.

Insurance

The Company carries insurance coverage on its properties of types and in amounts that it believes are in line with coverage customarily obtained by owners of similar properties. In response to the uncertainty in the insurance market following the terrorist attacks of September 11, 2001, the Federal Terrorism Risk Insurance Act, or TRIA, was enacted in November 2002 to require regulated insurers to make available coverage for certified acts of terrorism (as defined by the statute) through December 31, 2004, which date was extended to December 31, 2005 by the United States Department of Treasury on June 18, 2004. TRIA expires on December 31, 2005, and the Company cannot currently anticipate whether it will be extended. The property insurance program provides a $640 million per occurrence limit, including coverage for “certified acts of terrorism” as defined by TRIA. Additionally, the program provides $615 million of coverage for acts of terrorism

14

BOSTON PROPERTIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

other than those “certified” under TRIA. The Company also carries nuclear, biological and chemical terrorism insurance coverage with a $640 million per occurrence limit for “certified acts of terrorism” as defined by TRIA, which is provided by IXP, Inc. as a direct insurer. Under TRIA, this nuclear, biological and chemical terrorism insurance coverage is backstopped by the Federal Government after the payment of the required deductible and 10% coinsurance.

The Company also carries earthquake insurance on its properties located in areas known to be subject to earthquakes in an amount and subject to deductibles and self-insurance that the Company believes are commercially reasonable. Specifically, the Company carries earthquake insurance which covers its San Francisco portfolio with a $120 million per occurrence limit and a $120 million aggregate limit, $20 million of which is provided by IXP, Inc., as a direct insurer. The amount of the Company’s earthquake insurance coverage may not be sufficient to cover losses from earthquakes. As a result of increased costs of coverage and decreased availability, the amount of third-party earthquake insurance that the Company may be able to purchase on commercially reasonable terms may be reduced. In addition, the Company may discontinue earthquake insurance on some or all of its properties in the future if the premiums exceed the Company’s estimation of the value of the coverage.

In January 2002, the Company formed a wholly-owned taxable REIT subsidiary, IXP, Inc., or IXP, to act as a captive insurance company and be one of the elements of the Company’s overall insurance program. IXP acts as a direct insurer with respect to a portion of the Company’s earthquake insurance coverage for its Greater San Francisco properties and its nuclear, biological and chemical terrorism insurance coverage for “certified acts of terrorism” under TRIA. Insofar as the Company owns IXP, it is responsible for its liquidity and capital resources, and the accounts of IXP are part of the Company’s consolidated financial statements. If the Company experiences a loss and IXP is required to pay under its insurance policy, the Company would ultimately record the loss to the extent of IXP’s required payment. Therefore, insurance coverage provided by IXP should not be considered as the equivalent of third-party insurance, but rather as a modified form of self-insurance.

The Company continues to monitor the state of the insurance market in general, and the scope and costs of coverage for acts of terrorism in particular, but it cannot anticipate what coverage will be available on commercially reasonable terms in future policy years. There are other types of losses, such as from wars, acts of nuclear, biological or chemical terrorism other than those “certified” under TRIA, or the presence of mold at the Company’s properties, for which the Company cannot obtain insurance at all or at a reasonable cost. With respect to such losses and losses from acts of terrorism, earthquakes or other catastrophic events, if the Company experiences a loss that is uninsured or that exceeds policy limits, the Company could lose the capital invested in the damaged properties, as well as the anticipated future revenues from those properties. Depending on the specific circumstances of each affected property, it is possible that the Company could be liable for mortgage indebtedness or other obligations related to the property. Any such loss could materially and adversely affect the Company’s business and financial condition and results of operations.

7. Minority Interests

Minority interests in the Company relate to the interest in the Operating Partnership that is not owned by the Company and interests in property partnerships that are not owned by the Company. As of September 30, 2004, the minority interest in the Operating Partnership consisted of 21,707,428 OP Units, 169,838 LTIP Units and 4,124,700 Series Two Preferred Units (or 5,412,996 OP Units on an as converted basis) held by parties other than the Company.

On May 4, 2004, 1,070,437 Series Two Preferred Units of the Company’s Operating Partnership were converted by the holders into 1,404,772 OP Units. On August 16, 2004 and August 26, 2004, 65,525 and 140,000 Series Two Preferred Units of the Company’s Operating Partnership were converted by the holders into 85,990

15

BOSTON PROPERTIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

and 183,727 OP Units, respectively. The OP Units were subsequently presented by the holders for redemption and were redeemed by the Company in exchange for an equal number of shares of Common Stock. The aggregate book value of the Preferred Units that were converted, as measured for each Preferred Unit on the date of its conversion, was approximately $42.2 million. The difference between the aggregate book value and the purchase price of these Preferred Units was approximately $38.4 million, which increased the recorded value of the Company’s net assets. In addition, the Company paid the accrued preferred distributions due to the holders of Preferred Units that were converted. As a result of these conversions, the Operating Partnership had 4,124,700 Series Two Preferred Units outstanding as of September 30, 2004.

On August 16, 2004, the Operating Partnership paid a distribution on its outstanding Series Two Preferred Units of $0.8726 per unit.

On September 16, 2004, Boston Properties, Inc., as general partner of the Operating Partnership, declared a distribution on the OP Units and LTIP Units in the amount of $0.65 per OP Unit or LTIP Unit payable on October 29, 2004 to holders of record of OP Units and LTIP Units on September 30, 2004.

8. Stockholders’ Equity

As of September 30, 2004, the Company had 108,986,697 shares of Common Stock outstanding.

On March 3, 2004, the Company completed a public offering of 5,700,000 shares of its Common Stock at a price to the public of $51.40 per share. The proceeds from this public offering, net of underwriters’ discount and offering costs, totaled approximately $291.1 million.

On September 16, 2004, the Board of Directors of the Company declared a third quarter dividend in the amount of $0.65 per share of Common Stock payable on October 29, 2004 to shareholders of record as of the close of business on September 30, 2004.

9. Losses from Early Extinguishments of Debt

During the nine months ended September 30, 2004 and 2003, the Company recognized approximately $6.3 million and $1.5 million, respectively, related to early extinguishments of debt, consisting primarily of payments of prepayment fees and the write-off of unamortized deferred financing costs. These amounts have been reflected as “Losses from early extinguishments of debt” in the “Expenses” section of the Consolidated Statements of Operations.

10. Discontinued Operations

Effective January 1, 2002, the Company adopted the provisions of SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” which superceded SFAS No. 121. SFAS No. 144 requires that long-lived assets that are to be disposed of by sale be measured at the lesser of book value or fair value less cost to sell. In addition, it broadens the presentation of discontinued operations to include more disposal transactions.

During the nine months ended September 30, 2003, the Company sold 875 Third Avenue, a Class A office property totaling approximately 712,000 net rentable square feet located in New York City, New York and the Candler Building, a Class A office property totaling approximately 541,000 net rentable square feet located in Baltimore, Maryland.

During the nine months ended September 30, 2004, the Company sold the following properties:

(1) 430 Rozzi Place, an industrial property totaling 20,000 net rentable square feet located in South San Francisco, California;

(7) 204 Second Avenue, a Class A office property totaling approximately 41,000 net rentable square feet located in Waltham, Massachusetts.

In addition, at September 30, 2004, the Company had designated as held for sale 560 Forbes Boulevard, an industrial property totaling approximately 40,000 net rentable square feet located in South San Francisco, California. The Company has presented the properties discussed above as discontinued operations in its Consolidated Statements of Operations for the three months and nine months ended September 30, 2004 and 2003. In addition, the Company sold 2300 N Street, a Class A office property totaling approximately 289,000 net rentable square feet located in Washington, D.C. during the nine months ended September 30, 2003, and Hilltop Office Center, comprised of nine office/technical properties totaling approximately 143,000 net rentable square feet located in South San Francisco, California during the nine months ended September 30, 2004. Due to the Company’s continuing involvement in the management, for a fee, of these properties through an agreement with the buyers, these properties are not categorized as discontinued operations in the accompanying Consolidated Statements of Operations. As a result, the gain on sale related to Hilltop Office Center in South San Francisco, totaling approximately $6.8 million (net of minority interests share of approximately $8.7 million) and 2300 N Street in Washington, D.C., totaling approximately $52.8 million (net of minority interest share of approximately $11.5 million), have been reflected as “Gains on sales of real estate and other assets, net of minority interest” in the Consolidated Statements of Operations for the nine months ended September 30, 2004 and 2003, respectively.

The following table summarizes income from discontinued operations (net of minority interest) and the related realized gains on sales of real estate (net of minority interest) for the three months and nine months ended September 30, 2004 and 2003 (in thousands):

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

At September 30, 2004, the Company had designated as held for sale 560 Forbes Boulevard, an industrial property totaling approximately 40,000 net rentable square feet located in South San Francisco, California. The anticipated sales price exceeds the carrying value at September 30, 2004.

The Company’s application of SFAS No. 144 results in the presentation of the net operating results of these qualifying properties sold during 2004 and 2003 as income from discontinued operations for all periods presented. In addition, SFAS No. 144 results in the gains on sale of these qualifying properties totaling approximately $26.2 million (net of minority interests share of approximately $5.5 million) and $73.4 million (net of minority interest share of approximately $16.3 million) to be reflected as “Gains on sales of real estate from discontinued operations, net of minority interest” in the accompanying Consolidated Statements of Operations for the nine months ended September 30, 2004 and 2003, respectively. The application of SFAS No. 144 does not have an impact on net income available to common shareholders. SFAS No. 144 only impacts the presentation of these properties within the Consolidated Statements of Operations.

11. Earnings Per Share

Earnings per share (“EPS”) has been computed pursuant to the provisions of SFAS No. 128. The following table provides a reconciliation of both the net income and the number of common shares used in the computation of basic EPS, which is calculated by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during the period. During the period ended June 30, 2004, the Company adopted EITF 03-6 “Participating Securities and the Two-Class Method under FASB 128” (“EITF 03-6”), which provides further guidance on the definition of participating securities. Pursuant to EITF 03-6, the Company’s Series Two Preferred Units are considered participating securities. Accordingly, for the reporting periods in which the Operating Partnership’s net income is in excess of distributions paid on the OP Units, LTIP Units and Series Two Preferred Units, such income is allocated to the OP Units, LTIP Units, and Series Two Preferred Units in proportion to their respective interests. Prior periods have been restated to conform to the provisions of EITF 03-6. For the nine months ended September 30, 2004 and 2003, approximately $500,000 and $6,500,000, respectively, were allocated to the Series Two Preferred Units in excess of distributions and included in the Company’s computation of earnings per share. There were no amounts allocated to the Series Two Preferred Units in excess of distributions for the three months ended September 30, 2004 and 2003. Other potentially dilutive common shares, and the related impact on earnings, are considered when calculating diluted EPS.

12. Stock Option and Incentive Plan

During the nine months ended September 30, 2004, the Company issued 32,585 shares of restricted stock valued at approximately $1.6 million and 166,430 LTIP Units valued at approximately $8.3 million. An LTIP Unit is generally the economic equivalent of a share of restricted stock in the Company. The aggregate value of the LTIP Units is not included in “Unearned compensation” in the Consolidated Balance Sheets as it is reflected in “Minority interests.” Employees vest in restricted stock and LTIP Units over a five-year term. Restricted stock and LTIP Units are measured at fair value on the date of grant based on the number of shares or units granted and the price of the Company’s Common Stock on the date of grant as quoted on the New York Stock Exchange. Such value is generally recognized as an expense ratably over the corresponding employee service period. Stock-based compensation expense associated with restricted stock and LTIP Units was approximately $1.0 million and $0.5 million during the three months ended September 30, 2004 and 2003, respectively, and $3.2 million and $1.7 million during the nine months ended September 30, 2004 and 2003, respectively.

13. Segment Information

The Company’s segments are based on the Company’s method of internal reporting which classifies its operations by both geographic area and property type. The Company’s segments by geographic area are Greater Boston, Greater Washington, D.C., Midtown Manhattan, Greater San Francisco and Princeton, New Jersey. Segments by property type include: Class A Office, Office/Technical, Industrial and Hotels.

Asset information by segment is not reported because the Company does not use this measure to assess performance. Therefore, depreciation and amortization expense is not allocated among segments. Interest and other income, development and management services, general and administrative expenses, interest expense, depreciation and amortization expense, net derivative losses and losses from early extinguishments of debt are not included in net operating income as the internal reporting addresses these items on a corporate level.

Net operating income, or “NOI,” is a non-GAAP financial measure equal to net income available to common shareholders, the most directly comparable GAAP financial measure, plus minority interest in Operating Partnership, losses from early extinguishments of debt, net derivative losses, depreciation and amortization, interest expense and general and administrative expense, less gains on sales of real estate from discontinued operations (net of minority interest), income from discontinued operations (net of minority interest), gains on sales of real estate and other assets (net of minority interest), income from unconsolidated joint ventures, minority interest in property partnerships, interest and other income and development and management services income. The Company uses NOI internally as a performance measure and believes NOI provides useful information to investors regarding its financial condition and results of operations because it reflects only those income and expense items that are incurred at the property level. Therefore, the Company believes NOI is a useful measure for evaluating the operating performance of real estate assets.

The Company’s management also uses NOI to evaluate regional property level performance and to make decisions about resource allocations. Further, the Company believes NOI is useful to investors as a performance measure because, when compared across periods, 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. 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. NOI presented by the Company may not be comparable to NOI reported by other REITs that define NOI differently. The Company believes that in order to facilitate a clear understanding of its operating results, NOI should be

examined in conjunction with net income as presented in the Company’s consolidated financial statements. NOI should not be considered as an alternative to net income as an indication of the Company’s performance or to cash flows as a measure of liquidity or ability to make distributions.

14. Recent Accounting Pronouncements

In March 2004, the Emerging Issues Task Force reached a final consensus regarding Issue 03-6, “Participating Securities and the Two-Class Method under FAS 128.” The issue addresses a number of questions regarding the computation of earnings per share by companies that have issued securities other than common stock that participate in dividends and earnings of the issuing entity. Such securities are contractually entitled to receive dividends when and if the entity declares dividends on common stock. The issue also provides further guidance on applying the two-class method of calculating earnings per share once it is determined that a security is participating. The two-class method is an earnings allocation formula that determines earnings per share for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. This consensus was effective for the period ended June 30, 2004 and was applied by restating previously reported earnings per share. The Company has adopted the provisions of EITF 03-6, and has determined that the Series Two Preferred Units of the Company’s Operating Partnership constitute a participating security. The adoption of EITF 03-6 has resulted in a reduction of the Company’s earnings per share for those periods in which the Operating Partnership had undistributed earnings. Undistributed earnings were allocated to the Series Two Preferred Units based on their contractual rights to share in those earnings as if all the earnings for the period had been distributed.

15. Related Party Transactions

In connection with the acquisition of the Carnegie Center Portfolio in June 1998, the Operating Partnership entered into a development agreement with an affiliate of Mr. Alan B. Landis providing for up to approximately 2,000,000 square feet of development in or adjacent to the Carnegie Center office complex (the “Development Agreement”). In the past few years, the Operating Partnership and Mr. Landis have been unable to agree on terms of ancillary documents that were to be entered into under the Development Agreement and, on October 21, 2004, entered into an Agreement to modify several provisions of the Development Agreement (the “2004 Agreement”). Under the terms of the 2004 Agreement, the Operating Partnership and affiliates of Mr. Landis amended the Development Agreement to limit the rights of Mr. Landis and his affiliates to participate in the development of properties under the Development Agreement. Among other things, Mr. Landis has agreed that (1) Mr. Landis and his affiliates will have no right to participate in any entity formed to acquire land parcels or the development company formed by the Operating Partnership to provide development services under the Development Agreement, (2) Mr. Landis will have no right or obligation to play a role in development activities engaged in by the development company formed by the Operating Partnership under the Development Agreement or receive compensation from the development company, (3) the affiliate of Mr. Landis will have no right to receive a contingent payment for developed properties based on stabilized returns and (4) Mr. Landis and his affiliates will have no right to sell any of the land parcels other than under certain existing arrangements. In exchange, the Company (together with the Operating Partnership) has agreed to:

• effective as of June 30, 1998, pay Mr. Landis $125,000 on January 1 of each year until the earlier of (A) January 1, 2018, (B) the termination of the Development Agreement or (C) the date on which all development properties under the Development Agreement have been conveyed pursuant to the Development Agreement, with $750,000, representing payments of this annual amount from 1998 to 2004, being paid currently and reflected in General and Administrative Expenses in the accompanying Consolidated Statements of Operations for the three months ended September 30, 2004; and

• pay an affiliate of Mr. Landis, in connection with the development of land parcels acquired under the Development Agreement, an aggregate fixed amount of $10.50 per rentable square foot of property developed (with a portion of this amount (i.e., $5.50) being subject to adjustment, in specified circumstances, based on future increases in the Consumer Price Index) in lieu of a contingent payment based on stabilized returns, which payment could have been greater or less than $10.50 per rentable square foot of property developed.

The Operating Partnership also continues to be obligated to pay an affiliate of Mr. Landis the purchase price of $20 per rentable square foot of property developed for each land parcel acquired as provided in the original Development Agreement. During the 20-year term of the Development Agreement, until such time, if any, as the Operating Partnership elects to acquire a land parcel, an affiliate of Mr. Landis will remain responsible for all carrying costs associated with such land parcel.

In addition, in connection with entering into the 2004 Agreement, Mr. Landis has resigned as a director of the Company, effective as of the earlier of (i) immediately prior to the Company’s 2005 annual meeting of stockholders and (ii) May 11, 2005, and has agreed that the Company will have no future obligation to nominate Mr. Landis as a director of the Company. The scheduled effective date of Mr. Landis’s resignation will afford the Board with time, prior to the next annual stockholders meeting, to review its size and overall composition and evaluate whether it would be appropriate to identify possible candidates for nomination as a new independent director to fill the vacancy created by Mr. Landis’s resignation. Mr. Landis did not resign because of a disagreement with the Company on any matter relating to the Company’s operations, policies or practices.

16. Subsequent Events

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 Company intends to leverage its regional operating platform to source and acquire properties that will generate opportunity for value creation through repositioning, capital improvements and/or leasing strategies. The Value-Added Fund will not engage in any ground-up development. The Value-Added Fund has total equity commitments of $140 million, of which the Company has committed $35 million. Assuming an estimated 65% leverage ratio, the Value-Added Fund is anticipated to have up to $400 million of total investments. The Company will receive asset management, property management, leasing and redevelopment fees, and if certain return thresholds are achieved will be entitled to an additional promoted interest.

On November 1, 2004, the Value-Added Fund completed the acquisition of Worldgate Plaza, a 322,000 square foot office complex located in Herndon, Virginia for a purchase price of approximately $78.2 million. The acquisition was financed with new mortgage indebtedness totaling $57.0 million and approximately $21.2 million in cash, of which the Company’s share was $5.3 million. The mortgage financing bears interest at a variable rate equal to LIBOR + 0.89% and matures in October 2007, with two one-year extension options. In addition, the Value-Added Fund entered into an agreement with the lender to cap the interest rate at 9.5% for a nominal fee.

On November 8, 2004, a joint venture, of which the Company owned a 33.33% interest, exercised its right to terminate the purchase agreement to acquire the 21-acre site on the Boston waterfront known as Fan Pier. The venture forfeited its $2.5 million deposit, of which the Company’s share was $0.8 million. The Company expects to recognize approximately $1.1 million of general and administrative expense in the fourth quarter of 2004, which includes approximately $0.3 million of related due diligence costs.

Such statements are subject to risks, uncertainties and assumptions and are not guarantees of future performance, which may be affected by known and unknown risks, trends, uncertainties and factors that are beyond our control. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, estimated or projected. We caution you that while forward-looking statements reflect our good-faith beliefs when we make them, they are not guarantees of future performance 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.

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:

• General risks affecting the real estate industry (including, without limitation, the inability to enter into or renew leases on favorable terms, dependence on tenants’ financial condition, and competition from other developers, owners and operators of real estate);

• Financing may not be available on favorable terms or at all, and our cash flow from operations and access to attractive capital may be insufficient to fund operations, acquisitions and developments;

• We may be unsuccessful in managing changes in our portfolio composition or integrating acquisitions successfully;

• Risks and uncertainties affecting property development and construction (including, without limitation, construction delays, cost overruns, inability to obtain necessary permits and public opposition to such activities);

• Risks associated with downturns in the national and local economies (including increased unemployment in our core markets), increases in interest rates, and volatility in the securities markets;

• Risks associated with an increase in the frequency and scope of changes in state and local tax laws and increases in the number of state and local tax audits;

• Costs of compliance with the Americans with Disabilities Act and other similar laws;

• Potential liability for uninsured losses and environmental contamination;

• Risks associated with our potential failure to qualify as a REIT under the Internal Revenue Code of 1986, as amended;

• Possible adverse changes in tax and environmental laws, as well as the impact of newly adopted accounting principles on our accounting policies and on period-to-period comparisons of financial results;

• 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.

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

26

rapidly changing environment. New risk factors emerge from time to time and it is not possible for management to predict all risk factors, nor can it 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 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 Forms 8-K or otherwise. 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 report.

Overview

We are a fully integrated self-administered and self-managed REIT and one of the largest owners and developers of Class A office properties in the United States. Our properties are concentrated in four core markets—Boston, midtown Manhattan, Washington, D.C. and San Francisco. We generate revenue and cash primarily by leasing our Class A office space to our tenants. Factors we consider when we lease space include creditworthiness of the tenant, the length of the lease, the rental rate to be paid, costs of tenant improvements, operating costs and real estate taxes, vacancy and general economic factors.

Our industry’s performance is generally predicated on a sustained pattern of job growth. Since the beginning of 2004, the United States economy has experienced continued, but modest, economic growth. In the third quarter of 2004, leasing activity and lease economics across our portfolio have either remained constant or shown slight improvements. In New York City, our largest market, some existing tenants, including legal and financial service firms, have either exercised expansion rights, leased additional space or are seeking additional space. We have experienced activity in Baltimore, MD, Richmond, VA and Northern Virginia where major tenants have renewed and in one case committed to taking new space which we are developing. In addition, during the third quarter, the Boston area hotels continued to show improvement in terms of both occupancy and daily rates. Office leasing conditions in the Boston central business district, Boston suburbs and San Francisco have yet to demonstrate any improvement. Nevertheless, we believe our operating environment is improving.

Our corporate strategy of owning high-quality office buildings concentrated in strong, supply-constrained markets and emphasizing long-term leases to creditworthy tenants has continued to lessen the overall impact of the weak fundamentals in the operating environment by limiting our lease expiration exposure both from natural lease expirations and from terminations due to tenant defaults. As a result, despite challenging market conditions, our overall occupancy has been relatively stable over the past several quarters and we expect this trend to continue throughout the remainder of 2004.

In the face of these challenging market conditions, we have followed a disciplined approach to managing our operations by focusing primarily on enhancing the value of our company through strategic sales and successful leasing efforts of our existing portfolio. Our existing capital structure has the ability to fund additional acquisitions and/or developments due to our refinancings as well as proceeds from common equity offerings. Our variable rate debt now consists entirely of our refinanced construction loan on Times Square Tower. Accordingly, our exposure to potentially greater costs associated with rising interest rates has been reduced. We are constantly reviewing our portfolio to identify potential asset acquisitions, opportunities for development and asset dispositions. Much of our recent focus has been on new development projects that we believe will produce superior returns and will drive our growth in the coming years.

27

The highlights of the three months ended September 30, 2004 included the following:

• We sold the following two non-core buildings aggregating approximately 93,000 square feet:

Date	Property	Gross Sales Price
8/1/04	Sugarland Business Park-Building One, Herndon, Virginia	$	7.8 million
9/28/04	204 Second Avenue, Waltham, Massachusetts	$	6.0 million

• In July 2004, we commenced construction of Seven Cambridge Center, a fully-leased, build-to-suit project with approximately 231,000 square feet of office, research laboratory and retail space plus parking for approximately 800 cars, located in Cambridge, Massachusetts. We have signed a lease for 100% of the space with the Massachusetts Institute of Technology for occupancy by its affiliate, the Eli and Edythe L. Broad Institute. We expect to invest approximately $145.9 million in this project and we expect to complete this project in the first quarter of 2006.

• On July 30, 2004, we entered into a lease with the Lockheed Martin Corporation (LMC) totaling approximately 182,000 square feet related to the development of a build-to-suit office building in Reston, Virginia. LMC currently leases more than 500,000 square feet in two buildings within the same office complex. We expect to invest approximately $45.8 million in this project and we expect to complete this project in the second quarter of 2006.

• On August 2, 2004, we entered into a joint venture with unrelated third parties to pursue the development of a Class A office building totaling approximately 305,000 square feet that will be part of a mixed-use development of office, retail and residential properties known as Wisconsin Place located in Chevy Chase, Maryland. The new development will sit above a shared four-story parking garage with over 1,700 parking spaces. We will have a 66.67% interest in the office building, a shared interest in the infrastructure, a nominal interest in the retail component and no interest in the residential component. We expect to invest approximately $25.7 million in this project.

• On August 3, 2004, we entered into a lease with Ann Taylor Stores Corporation, totaling approximately 300,000 square feet at Times Square Tower in New York City. Times Square Tower was placed in-service this quarter, is now approximately 83% leased.

• On September 24, 2004, we refinanced the construction loan on our New Dominion Technology Park Building Two property located in Herndon, Virginia. The original construction loan with an outstanding balance of $56.9 million bore interest at LIBOR + 1.25% and was scheduled to mature in December 2005. The new mortgage loan totaling $63.0 million requires interest-only payments at a fixed rate of 5.55% per annum until it matures in September 2014.

• On September 30, 2004, a joint venture in which we have a 35% interest refinanced the mortgage loan secured by 265 Franklin Street located in Boston, Massachusetts. The old mortgage loan totaling $54.0 million bore interest at a floating rate equal to LIBOR + 1.30% and was scheduled to mature on October 1, 2004. The new mortgage loan facility totaling $70.0 million is comprised of $55.0 million disbursed at closing and an additional $15.0 million available to be drawn to fund future tenant improvement and leasing costs. The new mortgage loan facility requires interest-only payments at a floating rate equal to LIBOR + 1.10% and matures in September 2007, with two one-year extension options.

• In September 2004, we commenced the redevelopment of our Capital Gallery property in Washington, D.C. Capital Gallery is a Class A office property totaling approximately 397,000 square feet. The project entails removing a three-story low-rise section of the property comprised of 100,000 square feet from in-service status and redeveloping it into a 10-story office building resulting in a total complex size of approximately 610,000 square feet upon completion. We expect to invest approximately $69.1 million in the project and we expect to complete this project by the end of 2005. In connection with the redevelopment project, we recognized an accelerated depreciation charge of approximately $2.6 million in the three months ended September 30, 2004, which represents the net book value of the portion of the three story low rise portion of the building which will be redeveloped.

28

• We placed in service New Dominion Tech. Park, Building Two, a 257,400 square foot Class A office property located in Herndon, Virginia. This project is 100% leased.

Transactions completed subsequent to September 30, 2004:

• On October 25, 2004, we 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 our existing markets. We intend to leverage our regional operating platform to source and acquire properties that will generate opportunity for value creation through repositioning, capital improvements and/or leasing strategies. The Value-Added Fund will not engage in any ground-up development. The Value-Added Fund has total equity commitments of $140 million, of which we have committed $35 million. Assuming an estimated 65% leverage ratio, the Value-Added Fund is anticipated to have up to $400 million of total investments. We will receive asset management, property management, leasing and redevelopment fees, and if certain return thresholds are achieved will be entitled to an additional promoted interest.

• On November 1, 2004, the Value-Added Fund completed the acquisition of Worldgate Plaza, a 322,000 square foot office complex located in Herndon, Virginia for a purchase price of approximately $78.2 million. The acquisition was financed with new mortgage indebtedness totaling $57.0 million and approximately $21.2 million in cash, of which our share was $5.3 million. The mortgage financing bears interest at a variable rate equal to LIBOR + 0.89% and matures in October 2007, with two one-year extension options. In addition, the Value-Added Fund entered into an agreement with the lender to cap the interest rate at 9.5% for a nominal fee.

• On November 8, 2004, a joint venture, of which we owned a 33.33% interest, exercised its right to terminate the purchase agreement, which was entered into on September 22, 2004, to acquire the 21-acre site on the Boston waterfront known as Fan Pier. The venture forfeited its $2.5 million deposit, of which our share was $0.8 million. We expect to recognize approximately $1.1 million of general and administrative expense in the fourth quarter of 2004, which includes approximately $0.3 million of related due diligence costs.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America, or GAAP, requires management to use judgment in the application of accounting policies, including making estimates and assumptions. We base our estimates on historical experience and on various other assumptions believed to be reasonable under the circumstances. These judgments affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. If our judgment or interpretation of the facts and circumstances relating to various transactions had been different, it is possible that different accounting policies would have been applied resulting in a different presentation of our financial statements. From time to time, we evaluate our estimates and assumptions. In the event estimates or assumptions prove to be different from actual results, adjustments are made in subsequent periods to reflect more current information. Below is a discussion of accounting policies that we consider critical in that they may require complex judgment in their application or require estimates about matters that are inherently uncertain.

Real Estate

Upon acquisitions of real estate, we assess the fair value of acquired tangible and intangible assets, including land, buildings, tenant improvements, above and below market leases, origination costs, acquired in-place leases, other identified intangible assets and assumed liabilities in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 141, “Business Combinations” and allocate the purchase price to the acquired assets and assumed liabilities, including land at appraised value and buildings at replacement cost.

29

We assess and consider fair value based on estimated cash flow projections that utilize appropriate discount and/or capitalization rates, as well as available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known and anticipated trends, and market and economic conditions. The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. We also consider an allocation of purchase price of other acquired intangibles, including acquired in-place leases that may have a customer relationship intangible value, including (but not limited to) the nature and extent of the existing relationship with the tenants, the tenant’s credit quality and expectations of lease renewals. Based on our acquisitions to date, our allocation to customer relationship intangible assets has been immaterial.

We record acquired “above and below” market leases at their fair values using a discount rate which reflects the risks associated with the leases acquired, equal to the difference between (1) the contractual amounts to be paid pursuant to each in-place lease and (2) management’s estimate of fair market lease rates for each corresponding in-place lease, measured over a period equal to the remaining term of the lease for above-market leases and the initial term plus the term of any below-market fixed rate renewal options for below-market leases. Other intangible assets acquired include amounts for in-place lease values that are based on our evaluation of the specific characteristics of each tenant’s lease. Factors to be considered include estimates of carrying costs during hypothetical expected lease-up periods considering current market conditions, and costs to execute similar leases. In estimating carrying costs, we include real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods, depending on local market conditions. In estimating costs to execute similar leases, we consider leasing commissions, legal and other related expenses.

Real estate is stated at depreciated cost. The cost of buildings and improvements includes the purchase price of property, legal fees and other acquisition costs. Costs directly related to the development of properties are capitalized. Capitalized development costs include interest, internal wages, property taxes, insurance, and other project costs incurred during the period of development.

Management reviews its long-lived assets used in operations for impairment when there is an event or change in circumstances that indicates an impairment in value. An asset is considered impaired when the undiscounted future cash flows are not sufficient to recover the asset’s carrying value. If such impairment is present, an impairment loss is recognized based on the excess of the carrying amount of the asset over its fair value. The evaluation of anticipated cash flows is highly subjective and is based in part on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results in future periods. Since cash flows on properties considered to be “long-lived assets to be held and used” as defined by SFAS No. 144 “Accounting for the Impairment or Disposal of Long-Lived Assets,” (“SFAS No. 144”) are considered on an undiscounted basis to determine whether an asset has been impaired, our established strategy of holding properties over the long term directly decreases the likelihood of recording an impairment loss. If our strategy changes or market conditions otherwise dictate an earlier sale date, an impairment loss may be recognized and such loss could be material. If we determine that impairment has occurred, the affected assets must be reduced to their fair value. No such impairment losses have been recognized to date.

SFAS No. 144 which was adopted on January 1, 2002, requires that qualifying assets and liabilities and the results of operations that have been sold, or otherwise qualify as “held for sale,” be presented as discontinued operations in all periods presented if the property operations are expected to be eliminated and we will not have significant continuing involvement following the sale. The components of the property’s net income that is reflected as discontinued operations include the net gain (or loss) on the eventual disposition of the property held for sale, operating results, depreciation and interest expense (if the property is subject to a secured loan). Following the classification of a property as “held for sale,” no further depreciation is recorded on the assets.

A variety of costs are incurred in the acquisition, development and leasing of our properties. After determination is made to capitalize a cost, it is allocated to the specific component of a project that is benefited.

30

Determination of when a development project is substantially complete and capitalization must cease involves a degree of judgment. Our capitalization policy on our development properties is guided by SFAS No. 34 “Capitalization of Interest Cost” and SFAS No. 67 “Accounting for Costs and the Initial Rental Operations of Real Estate Properties.” We consider a construction project as substantially completed and held available for occupancy upon the completion of tenant improvements, but no later than one year from cessation of major construction activity. We cease capitalization on the portion substantially completed and occupied or held available for occupancy, and capitalize only those costs associated with the portion under construction.

Investments in Unconsolidated Joint Ventures

Except for ownership interests in a variable interest entity, we account for our investments in joint ventures under the equity method of accounting because we exercise significant influence over, but do not control, these entities. These investments are recorded initially at cost, as Investments in Unconsolidated Joint Ventures, and subsequently adjusted for equity in earnings and cash contributions and distributions. Any difference between the carrying amount of these investments on our balance sheet and the underlying equity in net assets is amortized as an adjustment to equity in earnings of unconsolidated joint ventures over 40 years. Under the equity method of accounting, our net equity is reflected on the consolidated balance sheets, and our share of net income or loss from the joint ventures is included on the consolidated statements of operations. The joint venture agreements may designate different percentage allocations among investors for profits and losses, however, our recognition of joint venture income or loss generally follows the joint venture’s distribution priorities, which may change upon the achievement of certain investment return thresholds.

We serve as the development manager for the joint venture at 901 New York Avenue and Wisconsin Place currently under development. The profit on development fees received from these joint ventures is recognized to the extent attributable to the outside interest in the joint venture.

Revenue Recognition

Base rental revenue is reported on a straight-line basis over the terms of our respective leases. In accordance with SFAS No. 141, we recognize rental revenue of acquired in-place “above and below” market leases at their fair value over the terms of the respective leases. Accrued rental income represents rental income recognized in excess of rent payments actually received pursuant to the terms of the individual lease agreements. We maintain an allowance against accrued rental income for future potential tenant credit losses. The credit assessment is based on the estimated accrued rental income that is recoverable over the term of the lease. We also maintain an allowance for doubtful accounts for estimated losses resulting from the inability of tenants to make required rent payments. The computation of this allowance is based on the tenants’ payment history and current credit status, as well as certain industry or geographic specific credit considerations. If our estimates of collectibility differ from the cash received, the timing and amount of our reported revenue could be impacted. The average remaining term of our in-place tenant leases was approximately 7.4 years as of September 30, 2004. The credit risk is mitigated by the high quality of our existing tenant base, reviews of prospective tenants’ risk profiles prior to lease execution and continual monitoring of our portfolio to identify potential problem tenants.

Recoveries from tenants, consisting of amounts due from tenants for common area maintenance, real estate taxes and other recoverable costs, are recognized as revenue in the period the expenses are incurred. Tenant reimbursements are recognized and presented in accordance with Emerging Issues Task Force, or EITF, Issue 99-19 “Reporting Revenue Gross as a Principal versus Net as an Agent,” or Issue 99-19. Issue 99-19 requires that these reimbursements be recorded on a gross basis, as we are generally the primary obligor with respect to purchasing goods and services from third-party suppliers, have discretion in selecting the supplier and have credit risk.

Our hotel revenues are derived from room rentals and other sources such as charges to guests for long-distance telephone service, fax machine use, movie and vending commissions, meeting and banquet room revenue and laundry services. Hotel revenues are recognized as earned.

31

We record our development fees earned on real estate projects on the percentage of completion method described in AICPA Statement of Position (SOP) 81-1. Management fees that are contingent upon the collection of rents are recorded and earned based on a percentage of collected rents at the properties under management, and not on a straight line basis.

Gains on sales of real estate are recognized pursuant to the provisions of SFAS No. 66, “Accounting for Sales of Real Estate.” The specific timing of the sale is measured against various criteria in SFAS No. 66 related to the terms of the transactions and any continuing involvement in the form of management or financial assistance associated with the properties. If the sales criteria are not met, we defer gain recognition and account for the continued operations of the property by applying the finance, installment or cost recovery methods, as appropriate, until the sales criteria are met.

Depreciation and Amortization

We compute depreciation and amortization on our properties using the straight-line method based on estimated useful asset lives. In accordance with SFAS No. 141, we allocate the acquisition cost of real estate to land, building, tenant improvements, acquired “above-” and “below-” market leases, origination costs and acquired in-place leases based on management’s assessment of their fair values and depreciate or amortize these assets over their useful lives. The amortization of acquired “above-” and “below-” market leases and acquired in-place leases is recorded as an adjustment to revenue and depreciation and amortization, respectively, in the Consolidated Statements of Operations.

Results of Operations

At September 30, 2004, we owned or had interests in a portfolio of 126 properties (the “Total Property Portfolio”). As a result of changes within our Total Property Portfolio, the financial data presented below shows significant changes in revenue and expenses from period-to-period. Accordingly, we do not believe that our period-to-period financial data are comparable. Therefore, the comparison of operating results for the nine and three months ended September 30, 2004 and 2003 show separately changes attributable to the properties that were owned by us throughout each period compared (the “Same Property Portfolio”) and the changes attributable to the Total Property Portfolio.

In our analysis of operating results, particularly to make comparisons of net operating income 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 our “Same Property Portfolio.” The “Same Property Portfolio” therefore excludes properties placed in-service or acquired 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 Property Portfolio.

Net operating income, or “NOI,” is a non-GAAP financial measure equal to net income available to common shareholders, the most directly comparable GAAP financial measure, plus minority interest in Operating Partnership, net derivative losses, depreciation and amortization, interest expense and general and administrative expense, less gains on sales of real estate from discontinued operations (net of minority interest), income from discontinued operations (net of minority interest), gains on sales of real estate (net of minority interest), income from unconsolidated joint ventures, minority interest in property partnerships, interest and other income and development and management services income. We use NOI internally as a performance measure and believe 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 NOI is a useful measure for evaluating the operating performance of our real estate assets.

32

Our management also uses NOI to evaluate regional property level performance and to make decisions about resource allocations. Further, we believe NOI is useful to investors as a performance measure because, when compared across periods, 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. 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. NOI presented by us may not be comparable to NOI reported by other REITs that define NOI differently. We believe that in order to facilitate a clear understanding of our operating results, NOI should be examined in conjunction with net income as presented in our consolidated financial statements. 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 liquidity or ability to make distributions.

Comparison of the nine months ended September 30, 2004 to the nine months ended September 30, 2003.

The table below reflects selected operating information for the Same Property Portfolio and the Total Property Portfolio. The Same Property Portfolio consists of the 112 properties totaling approximately 29.5 million square feet of office space, including three hotel properties, acquired or placed in-service on or prior to January 1, 2003 and owned through September 30, 2004. The Total Property Portfolio includes amounts from properties either placed in-service or acquired after January 1, 2003 or disposed of on or prior to September 30, 2004.

In September 2004, we commenced the redevelopment of our Capital Gallery property in Washington, D.C. Capital Gallery is a Class A office property totaling approximately 397,000 square feet. The project entails removing a three-story low-rise section of the property comprised of 100,000 square feet from in-service status and developing it into a 10-story office building resulting in a total complex size of approximately 610,000 square feet upon completion. The classification of this property is included in Properties Repositioned for the nine months ended September 30, 2004.

Rental Revenue

The increase in rental revenue of $60.7 million in the Total Portfolio primarily relates to the purchase of the remaining interests in One and Two Discovery Square as of April 1, 2003, the remaining interests in One and Two Freedom Square as of August 5, 2003, 1333 New Hampshire Avenue on October 8, 2003 and the remaining interest in 140 Kendrick Street as of March 24, 2004, as well as the acquisition of 1330 Connecticut Avenue on April 1, 2004. These additions to the portfolio increased revenue by approximately $46.0 million, as detailed below:

		Revenue for the nine months ended September 30,
Property	Date Acquired	2004		2003		Change
		(in thousands)
One and Two Discovery Square	April 1, 2003	$	9,891	$	6,300	$	3,591

1330 Connecticut Avenue	April 1, 2004		7,219		—		7,219
Total		$	56,868	$	10,825	$	46,043

In addition, the placing into service of Times Square Tower and New Dominion Technology Park, Building Two during the third quarter of 2004, as well as Shaws Supermarket and Waltham Weston Corporate Center during 2003, increased revenue by approximately $23.4 million for the nine months ended September 30, 2004, as detailed below:

		Revenue for the nine months ended September 30,
Property	Date Placed in Service	2004		2003		Change
		(in thousands)
Times Square Tower	3rd Quarter 2004	$	20,770	$	1,889	$	18,881
Waltham Weston Corporate Center	1st Quarter 2003		4,846		3,192		1,654
Shaws Supermarket	3rd Quarter 2003		2,432		1,563		869
New Dominion Technology Park, Building Two	3rd Quarter 2004		2,022		—		2,022
Total		$	30,070	$	6,644	$	23,426

The aggregate increase in rental revenue was offset by a decrease of approximately $4.0 million due to the sale of 2300 N Street during 2003 and Hilltop Office Center during 2004, both of which have not been classified as discontinued operations due to our continued involvement in the management of the properties. The decrease in the remaining Same Property Portfolio reflects declining base rents of approximately $1.5 million and a decrease in straight-line rents of $4.5 million. Included in rental revenue is an increase of approximately $1.8 million which represents the portion we recognized from the settlement of litigation with a third-party vendor related to billing of prior years’ operating expenses. We anticipate that we will experience a roll down in rents for the remainder of 2004 and 2005 on our expiring leases which will be partially offset by increased occupancy and higher contributions from newly delivered buildings like Times Square Tower and New Dominion Technology Park, Building Two.

Termination Income

Termination income for the nine months ended September 30, 2004 was related to sixteen tenants across the portfolio that terminated their leases and made termination payments totaling approximately $3.4 million. This compared to termination income earned for the nine months ended September 30, 2003 related to seventeen tenants totaling $4.9 million. We do not anticipate receiving any termination income in the fourth quarter of 2004 and we anticipate receiving approximately $1.0 million in termination income in 2005.

35

Development and Management Services

Our third-party fee income increased approximately $1.5 million for the nine months of 2004 compared to 2003. Our existing third-party fees continue in Washington, D.C. with National Institute of Health and in New York at 90 Church Street, which collectively contributed $7.0 million to development and management services for the nine months ended September 30, 2004 compared to $4.9 million for the nine months ended September 30, 2003. As we complete certain third-party contracts we anticipate our third-party fee income to decrease significantly in 2005.

Interest and Other Income

Interest and other income increased by $7.4 million in the Total Portfolio for the nine months ended September 30, 2004. In the first quarter of 2004 we recognized a net amount of approximately $7.0 million in connection with the termination by a third-party of an agreement to enter into a ground lease with us. At the end of the third quarter of 2004, we had a cash balance of approximately $214 million. To the extent we do not use our cash balance to acquire properties, fund new developments, or reduce outstanding indebtedness, we anticipate interest income will remain flat through the end of the year.

Operating Expenses

Property operating expenses in the Total Portfolio (real estate taxes, utilities, insurance, repairs and maintenance, cleaning and other property-related expenses) increased by $12.9 million. Approximately $10.4 million of the increase is due to the additions of One and Two Discovery Square, One and Two Freedom Square, 1333 New Hampshire Avenue, 140 Kendrick Street and 1330 Connecticut Avenue. In addition, the placing into service of Times Square Tower and New Dominion Technology Park, Building Two during the third quarter of 2004, as well as Shaws Supermarket and Waltham Weston Corporate Center during 2003, increased operating expenses by approximately $2.6 million for the nine months ended September 30, 2004.

This increase was offset by a decrease of an aggregate of $1.1 million related to the sales of 2300 N Street in 2003 and Hilltop Office Center in 2004, both of which have not been classified as discontinued operations due to our continued involvement in the management of the properties. The remaining increases are due to slight increases in Same Property Portfolio operating expenses of approximately $1.0 million.

Hotel Net Operating Income

Net operating income for the hotel properties increased by approximately $1.6 million, or approximately 13.7%, for the nine months ended September 30, 2004 compared to the nine months ended September 30, 2003.

The following reflects our occupancy and rate information for the three hotel properties for the nine months ended September 30, 2004 and 2003:

	2004			2003			Increase (Decrease)
Occupancy		82.6	%		78.3	%	5.5	%
Average daily rate	$	169.73		$	162.64		4.4	%
Revenue per available room, REVPAR	$	140.68		$	127.73		10.1	%

Other Expenses

General and Administrative

General and administrative expenses in the Total Portfolio increased during the nine months ended September 30, 2004 as compared to the nine months ended September 30, 2003 by $4.5 million, or 13.34%. An aggregate of $1.4 million of the increase is attributable to changes in the form of long-term equity-based compensation, as further described below. Deal costs in relation to the formation of the Value-Added Fund,

36

Wisconsin Place and Fan Pier increased general and administrative expenses approximately $0.2 million for the nine months ended September 30, 2004. A one-time expense of $750,000 represents our payment to Alan B. Landis in connection with the amendment to the development agreement, as further detailed in Note 15 to the Consolidated Financial Statements. The remaining increase is due to compensation related expenses increases during 2004.

In 2003, we transitioned to using solely restricted stock and/or long-term incentive units of limited partnership of partnership interest in Boston Properties Limited Partnership, or LTIP Units, as opposed to granting stock options and restricted stock, under the 1997 Stock Option and Incentive Plan as our primary vehicle for employee equity compensation. An LTIP unit is generally the economic equivalent of a share of our restricted stock. Employees vest in restricted stock and LTIP Units over a five-year term (0%, 0%, 25%, 35%, 40%). Restricted stock and LTIP Units are measured at fair value on the date of grant based on the number of shares or units granted and the price of our common stock on the date of grant as quoted on the New York Stock Exchange. Such value is recognized as an expense ratably over the corresponding employee service period. To the extent restricted stock or LTIP Units are forfeited prior to vesting, the corresponding previously recognized expense is reversed as an offset to “Stock-based compensation.” Stock-based compensation expense associated with restricted stock was approximately $3.2 million during the nine months ended September 30, 2004. Stock-based compensation expense associated with $6.1 million of restricted stock that was granted in January 2003 will generally be expensed ratably as such restricted stock vests over a five-year vesting period. Stock-based compensation associated with approximately $9.7 million of restricted stock and LTIP Units that were granted in January 2004 will also be incurred ratably as such restricted stock and LTIP Units vest. To the extent we continue our policy of granting restricted equity awards in lieu of stock options at levels comparable to the grants made in 2003 and 2004, we will continue to experience annual cost increases associated with equity-based compensation until 2008 at which time the annual incremental increase in stock-based compensation expense will be substantially realized.

Interest Expense

Interest expense for the Total Portfolio increased approximately $2.4 million. The majority of the increase is due to the cessation of interest capitalization at Times Square Tower and New Dominion Technology, Building Two, as well as the acquisition of the outside interest in 140 Kendrick Street and 1330 Connecticut Avenue, which were offset by the repayment of outstanding mortgage debt on One and Two Reston Overlook, as well as the Lockheed Martin building, in the beginning of 2004. Our floating rate debt now consists entirely of our refinanced construction loan on Times Square Tower. The following summarizes our debt outstanding as of September 30, 2004 compared with 2003.

Depreciation and Amortization

Depreciation and amortization expense for the Total Portfolio increased as a result of the placing into service of Times Square Tower and New Dominion Technology Park, Building Two as well as the acquisitions of One and Two Discovery Square, One and Two Freedom Square, 1333 New Hampshire Avenue, the remaining outside interest in 140 Kendrick Street, and 1330 Connecticut Avenue. These additions to the portfolio increased depreciation and amortization expense by approximately $15.6 million, as detailed below:

In September 2004, we commenced the redevelopment of our Capital Gallery property in Washington, D.C. which is classified as Properties Repositioned for the nine months ended September 30, 2004. In connection with the redevelopment project, we recognized an accelerated depreciation charge of approximately $2.6 million in the third quarter of 2004, which represents the net book value of the portion of the three story low rise portion of the building which will be redeveloped.

Capitalized Costs

Costs directly related to the development of rental properties are capitalized and included in real estate assets. Capitalized development costs include interest, wages, property taxes, insurance and other project costs incurred during the period of development. Capitalized wages for the nine months ended September 30, 2004 and 2003 were $4.4 million and $3.8 million, respectively. These costs are not included in the general and administrative expenses discussed above. Interest capitalized for the nine months ended September 30, 2004 and 2003 was $10.1 million and $14.0 million, respectively. These costs are not included in the interest expense referenced above.

Net Derivative Losses

Net derivative losses for the Total Portfolio represent the adjustments to fair value and cash settlements of our derivative contract that are not effective for accounting purposes. The fair value of our derivative contract, which was $2.9 million at September 30, 2004, is included on our balance sheet. As a result of our modification to this derivative contract in August 2003, we will have no further earnings volatility on the remaining derivative contract. See Part I-Item 3- Quantitative and Qualitative Disclosures about Market Risk.

Joint Ventures

The decrease in income from unconsolidated joint ventures in the Total Portfolio is related to purchasing the remaining interests in 140 Kendrick Street, One and Two Discovery Square and One and Two Freedom Square. 140 Kendrick Street is included in the Total Portfolio as of March 24, 2004. One and Two Discovery Square are

38

included in the Total Portfolio as of April 1, 2003. One and Two Freedom Square are included in the Total Portfolio as of August 5, 2003. The reclassification of these properties caused the overall income from unconsolidated joint ventures to decrease $3.4 million, which was offset by an increase in Same Property Joint Venture income of approximately $0.8 million.

Other

The decrease in income from discontinued operations in the Total Portfolio for the nine months ended September 30, 2004 was a result of properties sold or designated as held for sale during the end of 2003 and beginning of 2004 which are no longer included as of September 30, 2004. Below is a list of properties included in discontinued operations for the nine months ended September 30, 2004 and 2003:

Nine months ended September 30, 2004	Nine months ended September 30, 2003

Gains on the sales of real estate for the nine months ended September 30, 2004 in the Total Portfolio relate to the sale of Hilltop Office Center and a land parcel in Burlington, MA. Gains for the nine months ended September 30, 2003 primarily relate to the sale of 2300 N Street. These properties are not included in discontinued operations due to our continuing involvement in the management, for a fee, of these properties after the sales.

Gains on sales of real estate from discontinued operations for the nine months ended September 30, 2004 in the Total Portfolio primarily related to the gain recognized on 204 Second Ave, Sugarland Business Park-Building One, Sugarland Business Park-Building Two, The Arboretum, Decoverly Two, Three, and Seven, 430 Rozzi Place and 38 Cabot Boulevard. Gains on sales of real estate from discontinued operations for the year ended September 30, 2003 primarily related to the gains recognized on the sale of 875 Third Avenue and The Candler Building.

Comparison of the three months ended September 30, 2004 to the three months ended September 30, 2003.

The table below reflects selected operating information for the Same Property Portfolio and the Total Property Portfolio. The Same Property Portfolio consists of the 116 properties totaling approximately 30.2 million square feet of office space, including three hotel properties, acquired or placed in-service on or prior to July 1, 2003 and owned through September 30, 2004. The Total Property Portfolio includes amounts from properties either placed in-service or acquired after July 1, 2003 or disposed of on or prior to September 30, 2004.

In September 2004, we commenced the redevelopment of our Capital Gallery property in Washington, D.C. Capital Gallery is a Class A office property totaling approximately 397,000 square feet. The project entails removing a three-story low-rise section of the property comprised of 100,000 square feet from in-service status and developing it into a 10-story office building resulting in a total complex size of approximately 610,000 square feet upon completion. The classification of this property is included in Properties Repositioned for the three months ended September 30, 2004.

BOSTON PROPERTIES, INC.

Rental Revenue

The increase in rental revenue of $27.3 million in the Total Portfolio relates in part to the purchase of the remaining interests in One and Two Freedom Square as of August 5, 2003 and 140 Kendrick Street on March 24, 2004, as well as the purchase of 1333 New Hampshire Avenue on October 8, 2003 and 1330 Connecticut Avenue on April 1, 2004. These additions to the portfolio increased revenue by approximately $13.3 million, as detailed below:

In addition, the placing into service of New Dominion Technology Park, Building Two and Times Square Tower in the current quarter increased revenue $2.0 million and $12.7 million, respectively, for the quarter ended September 30, 2004. Same Property Portfolio rental revenue increased slightly for the three months ended, reflecting increasing base rents of approximately $1.0 million offset by a decrease in straight-line rent of $2.6 million. Included in rental revenue is an increase of approximately $1.8 million which represents the portion we recognized from the settlement of ongoing litigation with a third-party vendor related to billing of prior years’ operating expenses. We anticipate that we will experience a roll down in rents for the remainder of 2004 and in 2005 on our expiring leases which will be partially offset by increased occupancy and higher contributions from newly delivered buildings like Times Square Tower and New Dominion Technology, Building Two.

In September 2004, we commenced the redevelopment of our Capital Gallery property in Washington, D.C. Capital Gallery is a Class A office property totaling approximately 397,000 square feet. The project entails removing a three-story low-rise section of the property comprised of 100,000 square feet from in-service status and developing it into a 10-story office building resulting in a total complex size of approximately 610,000 square feet upon completion. The development cost is estimated at approximately $69.0 million and is expected to be completed by the end of 2005. The classification of this property is included in Properties Repositioned for the three months ended September 30, 2004.

Termination Income

We recognized termination income related to eight tenants totaling $1.8 million for the three months ended September 30, 2004, compared to termination income earned for the three months ended September 30, 2003 related to nine tenants totaling $1.7 million. We do not anticipate receiving any termination income in the fourth quarter of 2004 and we anticipate receiving approximately $1.0 million in termination income in 2005.

Development and Management Services

Our third-party fee income increased $2.2 million for the third quarter of 2004 compared to the third quarter of 2003. Our existing third-party fees continue in Washington, D.C. with National Institute of Health and New York at 90 Church Street, which collectively contributed $2.1 million to development and management services for the three months ended September 30, 2004. As we complete certain third-party contracts we anticipate our third-party fee income to decrease significantly in 2005.

Interest and Other Income

Interest and other income decreased by $0.2 million in the Total Portfolio for the three months ended September 30, 2004. At the end of the third quarter we had a cash balance of approximately $214 million. To the extent we do not use our cash balance to acquire properties, fund new developments or reduce outstanding indebtedness, we anticipate interest income will remain flat through the end of the year.

Operating Expenses

Property operating expenses in the Total Portfolio (real estate taxes, utilities, insurance, repairs and maintenance, cleaning and other property-related expenses) increased by $3.4 million. Approximately $3.1 million of the increase is due to the additions of 1333 New Hampshire Avenue, One and Two Freedom Square, 140 Kendrick Street and 1330 Connecticut Avenue. In addition, the placing into service of New Dominion Technology Park, Building Two and Times Square Tower increased operating expenses by $1.5 million.

These increases were offset by a decrease of $1.1 million in Same Property Portfolio operating expenses. An increase of approximately $1.3 million is due to real estate tax expenses, the majority coming from our properties in New York City. Operating expense decreases in repair and maintenance, utilities and insurance totaled approximately $2.3 million for the three months ended September 30, 2004.

Hotel Net Operating Income

Net operating income for the hotel properties increased by $1.3 million, or approximately 28.6%, for the three months ended September 30, 2004 compared to the three months ended September 30, 2003.

The following reflects our occupancy and rate information for the three hotel properties for the three months ended September 30, 2004 and 2003:

	2004			2003			Increase (Decrease)
Occupancy		89.6	%		86.9	%	3.1	%
Average daily rate	$	184.18		$	165.73		11.1	%
Revenue per available room, REVPAR	$	165.40		$	144.91		14.1	%

Other Expenses

General and Administrative

General and administrative expenses in the Total Portfolio increased during the three months ended September 30, 2004 as compared to the three months ended September 30, 2003 by $1.8 million, or 16.27%. An aggregate of $0.5 million of the increase is attributable to changes in the form of long-term equity-based compensation, as further described below. Deal costs in relation to the formation of the Value-Added Fund, Wisconsin Place and Fan Pier increased general and administrative expenses approximately $0.2 million for the three months ended September 30, 2004. A one-time expense of $750,000 represents our payment to Alan B. Landis in connection with the amendment to the development agreement, as further detailed in Note 15 to the Consolidated Financial Statements. The remaining increase is due to compensation related expenses increases during 2004.

In 2003, we transitioned to using solely restricted stock and/or long-term incentive units of limited partnership or partnership interest in Boston Properties Limited Partnership, or LTIP Units, as opposed to granting stock options and restricted stock, under the 1997 Stock Option and Incentive Plan as our primary vehicle for employee equity compensation. An LTIP Unit is generally the economic equivalent of a share of our

42

BOSTON PROPERTIES, INC.

restricted stock. Employees vest in restricted stock and LTIP Units over a five-year term (0%, 0%, 25%, 35%, 40%). Restricted stock and LTIP Units are measured at fair value on the date of grant based on the number of shares or units granted and the price of our common stock on the date of grant as quoted on the New York Stock Exchange. Such value is recognized as an expense ratably over the corresponding employee service period. To the extent restricted stock or LTIP Units are forfeited prior to vesting, the corresponding previously recognized expense is reversed as an offset to “Stock-based compensation.” Stock-based compensation expense associated with restricted stock was approximately $1.0 million during the three months ended September 30, 2004. Stock-based compensation expense associated with $6.1 million of restricted stock that was granted in January 2003 will generally be expensed ratably as such restricted stock vests over a five-year vesting period. Stock-based compensation associated with approximately $9.7 million of restricted stock and LTIP Units that were granted in January 2004 will also be incurred ratably as such restricted stock and LTIP Units vest. To the extent we continue our policy of granting restricted equity awards in lieu of stock options at levels comparable to the grants made in 2003 and 2004, we will continue to experience annual cost increases associated with equity-based compensation until 2008 at which time the annual incremental increase in stock-based compensation expense will be substantially realized.

Interest Expense

Interest expense for the Total Portfolio increased approximately $2.4 million for the three months ended September 30, 2004. Our total debt outstanding increased approximately $100 million from September 30, 2003 to 2004. During the third quarter of 2004 Times Square Tower and New Dominion Technology Park, Building Two were placed into service which increased interest expense by approximately $3.1 million. Excluding the impact of our construction loans for which interest is capitalized, our mortgage loan balances have decreased approximately $41 million due to principle payments and the repayment of outstanding mortgage debt on One and Two Reston Overlook, as well as Lockheed Martin, offset by the assumption of mortgage debt on 1330 Connecticut Avenue and 140 Kendrick Street. The decrease in these balances contributed to lower interest expense for the three months ended September 30, 2004 compared to 2003.

Our weighted average rate on variable rate debt has decreased primarily as a result of refinancing of the construction loan facility on Times Square Tower during January 2004 offset by an increase in short-term interest rates. The following summarizes our debt outstanding for the three months ended September 30, 2004 compared with 2003.

Depreciation and Amortization

Depreciation and amortization expense for the Total Portfolio increased as a result of the placing into service of Times Square Tower and New Dominion Technology Park, Building Two as well as the acquisitions of One and Two Freedom Square, 1333 New Hampshire Avenue, the remaining outside interest in 140 Kendrick Street, and 1330 Connecticut Avenue. These additions to the portfolio increased depreciation and amortization by approximately $5.6 million, as detailed below:

Property	Acquired/Placed in Service	Depreciation for the three months ended September 30,
		2004		2003		Change

New Dominion Technology Park, Building Two	Placed in-service		361				361
Total Additions		$	6,885	$	1,318	$	5,567

Increases in depreciation and amortization expense for the Same Property Portfolio represented $5.1 million. In September 2004, we commenced the redevelopment of our Capital Gallery property in Washington, D.C. which is classified as Properties Repositioned for the nine months ended September 30, 2004. In connection with the redevelopment project, we recognized an accelerated depreciation charge of approximately $2.6 million in the third quarter of 2004 which represents the net book value of the portion of the three story low rise portion of the building which will be redeveloped.

Capitalized Costs

Costs directly related to the development of rental properties are capitalized and included in real estate assets. Capitalized development costs include interest, wages, property taxes, insurance and other project costs incurred during the period of development. Capitalized wages for the three months ended September 30, 2004 and 2003 were $1.5 million and $1.3 million, respectively. These costs are not included in the general and administrative expenses discussed above. Interest capitalized for the three months ended September 30, 2004 and 2003 was $1.8 million and $5.0 million, respectively. These costs are not included in the interest expense referenced above. During the three months ended September 30, 2004 we placed Times Square Tower and New Dominion Technology Park, Building Two into service.

Net Derivative Losses

Net derivative losses for the Total Portfolio represent the adjustments to fair value and cash settlements of our derivative contract that are not effective for accounting purposes. The fair value of our derivative contract, which was $2.9 million at September 30, 2004, is included on our balance sheet. As a result of our modification to this derivative contract in August 2003, we will have no further earnings volatility on the remaining derivative contract. See Item 3- Quantitative and Qualitative Disclosures about Market Risk.

Joint Ventures

The decrease in income from unconsolidated joint ventures in the Total Portfolio is related to the purchase of the remaining interests in 140 Kendrick Street and One and Two Freedom Square. 140 Kendrick Street is

44

BOSTON PROPERTIES, INC.

included in the Total Portfolio as of March 24, 2004. One and Two Freedom Square are included in the Total Portfolio as of August 5, 2003. The reclassification of these properties caused the overall income from joint ventures to decrease approximately $1.0 million for the three months ended September 30, 2004 compared to the three months ended September 30, 2003.

Other

The decrease in income from discontinued operations in the Total Portfolio for the three months ended September 30, 2004 was a result of properties sold or designated as held for sale during the end of 2003 and beginning of 2004 which are no longer included for the quarter ended September 30, 2004. Below is a list of properties included in discontinued operations for the three months ended September 30, 2004 and 2003:

Three months ended September 30, 2004	Three months ended September 30, 2003
Sugarland Business Park-Building One	Sugarland Business Park-Building One
204 Second Ave	204 Second Ave
560 Forbes Boulevard	560 Forbes Boulevard
	Decoverly Two, Three, Six and Seven
	38 Cabot Boulevard
	The Arboretum
	430 Rozzi Place
	Sugarland Business Park-Building Two

Gains on the sales of real estate for the three months ended September 30, 2003 in the Total Portfolio relate to the transfer of certain mortgage issuance costs that resulted in a gain of $1.3 million (net of minority interest share of $0.3 million.)

Gains on sales of real estate from discontinued operations for the quarter ended September 30, 2004 in the Total Portfolio primarily related to the gain recognized on Sugarland Business Park-Building One, Sugarland Business Park-Building Two and 204 Second Ave. There were no gains on sales of real estate from discontinued operations for the quarter ended September 30, 2003.

Liquidity and Capital Resources

General

Our principal liquidity needs for the next twelve months are to:

• fund normal recurring expenses;

• meet debt service requirements;

• fund capital expenditures, including tenant improvements and leasing costs;

• fund current development costs not covered under construction loans;

• fund new property acquisitions; and

• make the minimum distribution required to maintain our REIT qualification under the Internal Revenue Code of 1986, as amended.

We believe that these needs will be satisfied using cash flows generated by operations and provided by financing activities. Rental revenue, recovery income from tenants, and other income from operations are our principal sources of capital used to pay operating expenses, debt service, recurring capital expenditures and the

45

BOSTON PROPERTIES, INC.

minimum distribution required to maintain our REIT qualification. We seek to increase income from our existing properties by maintaining quality standards for our properties that promote high occupancy rates and permit increases in rental rates while reducing tenant turnover and controlling operating expenses. Our sources of revenue also include third-party fees generated by our office real estate management, leasing, development and construction businesses. Consequently, we believe our revenue, together with proceeds from financing activities, will continue to provide the necessary funds for our short-term liquidity needs. However, material changes in these factors may adversely affect our net cash flows. Such changes, in turn, would adversely affect our ability to fund distributions, debt service payments and tenant improvements. In addition, a material adverse change in our cash provided by operations may affect the financial covenants under our unsecured line of credit and unsecured senior notes.

Our principal liquidity needs for periods beyond twelve months are for the costs of developments, property acquisitions, scheduled debt maturities, major renovations, expansions and other non-recurring capital improvements. We expect to satisfy these needs using one or more of the following:

• construction loans;

• long-term secured and unsecured indebtedness;

• income from operations;

• joint ventures;

• sales of real estate;

• issuances of our equity securities and/or additional preferred or common units of partnership interest in Boston Properties Limited Partnership; and

• our unsecured revolving line of credit or other short-term bridge facilities.

We draw on multiple financing sources to fund our long-term capital needs. Our line of credit is utilized primarily as a bridge facility to fund acquisition opportunities and meet short-term development and working capital needs. We fund our development projects with construction loans that may be partially guaranteed by Boston Properties Limited Partnership until project completion or lease-up thresholds are achieved. In March 2004 we completed a public offering of 5,700,000 shares of common stock, receiving net proceeds of approximately $291.1 million. In addition, during 2003 we completed three offerings of unsecured senior notes and we may, from time to time, utilize the bond market, asset backed mortgage financing and common and preferred equity as cost-effective capital sources for other long-term capital needs.

Cash Flow Summary

Cash and cash equivalents were $213.9 million and $37.6 million at September 30, 2004 and 2003, respectively, representing an increase of $176.3 million. The increase was a result of the following increases and decreases in cash flows:

	Three months ended September 30,
	(in thousands)
	2004			2003			Increase (Decrease)
Net cash provided by operating activities	$	303,664		$	339,030		$	(35,366	)
Net cash provided by (used in) investing activities	$	(119,644	)	$	285,664		$	(405,308	)
Net cash provided by (used in) financing activities	$	7,167		$	(642,348	)	$	649,515

Our principal source of cash flow is related to the operation of our office properties. In addition we have recycled capital through the sale of some of our properties and raised proceeds from secured and unsecured

46

BOSTON PROPERTIES, INC.

borrowings as well as the March 2004 public offering of 5,700,000 shares of common stock. Our operating cash flow on a period to period basis is impacted by the timing of interest payments on our senior unsecured notes which are payable semi-annually. The average remaining term of our tenant leases is approximately 7.4 years with occupancy rates historically in the range of 92% to 98%. Our properties provide a relatively consistent stream of cash flow that provides us with resources to pay operating expenses, debt service and fund quarterly dividend and distribution payment requirements.

Cash is used in investing activities to fund acquisitions, development and recurring and nonrecurring capital expenditures. We selectively invest in new projects that enable us to take advantage of our development, leasing, financing and property management skills and invest in existing buildings that meet our investment criteria. Cash used in investing activities for the three months ended September 30, 2004 consisted of the following:

	(in thousands)
Proceeds from the sales of real estate	$	103,779
The cash provided by investing is partially offset by:
Investments in unconsolidated joint ventures		(5,914	)
Recurring capital expenditures		(6,831	)

Hotel improvements, equipment upgrades and replacements		(238	)
Acquisitions/additions to real estate		(209,958	)
Net cash used in investing activities	$	(119,644	)

Cash provided by financing activities for the three months ended September 30, 2004 totaled approximately $7.2 million. This consisted of payments of dividends and distributions to shareholders and unitholders, minority partners and changes to our existing debt structure resulting in a net reduction of our total debt, including the repayment of certain mortgages and associated pre-payment penalties, utilizing the proceeds from sales of real estate assets and proceeds from our common stock offering in March 2004. Future debt payments are discussed below under the heading “Capitalization.”

Capitalization

At September 30, 2004, our total consolidated debt was approximately $5.0 billion. The weighted-average annual interest rate on our consolidated indebtedness was 6.34% and the weighted-average maturity was approximately 5.9 years. Our current capital structure provides us with significant acquisition and/or development borrowing capacity.

Debt to total 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. Our total market capitalization was approximately $12.6 billion at September 30, 2004. Total market capitalization was calculated using the September 30, 2004 closing stock price of $55.39 per common share and the following: (1) 108,986,697 shares of our common stock, (2) 21,707,428 outstanding common units of partnership interest in Boston Properties Limited Partnership (excluding common units held by Boston Properties, Inc.), (3) an aggregate of 5,412,996 common units issuable upon conversion of all outstanding preferred units of partnership interest in Boston Properties Limited Partnership, (4) an aggregate of 169,838 common units issuable upon conversion of all outstanding LTIP Units, assuming all conditions have been met for the conversion of the LTIP Units, and (5) our consolidated debt totaling approximately $5.0 billion. Our total consolidated debt at September 30, 2004 represented approximately 39.92% of our total market capitalization. This percentage will fluctuate with changes in the market price of our common stock and does not necessarily reflect our capacity to incur additional debt to finance our activities or our ability to manage our

47

BOSTON PROPERTIES, INC.

existing debt obligations. However, for a company like ours, whose assets are primarily income-producing real estate, the debt to total market capitalization ratio may provide investors with an alternate indication of leverage, so long as it is evaluated along with other financial ratios and the various components of our outstanding indebtedness.

Debt Financing

As of September 30, 2004, we had approximately $5.0 billion of outstanding indebtedness, representing 39.92% of our total market capitalization as calculated above under the heading “Capitalization,” consisting of $1.475 billion in publicly traded unsecured debt at an average interest rate of 5.95% with maturities of nine to eleven years and $3.5 billion of property-specific debt. We had no outstanding borrowings under our unsecured line of credit as of September 30, 2004. The table below summarizes our mortgage notes payable, our senior unsecured notes and our revolving line of credit at September 30, 2004 and 2003:

The variable rate debt shown above bears interest based on various spreads over the London Interbank Offered Rate or Eurodollar rates.

Unsecured Line of Credit

On January 17, 2003, we extended our $605.0 million unsecured revolving credit facility (the “Unsecured Line of Credit”) for a three year term expiring on January 17, 2006 with a provision for a one-year extension at our option, subject to certain conditions. Outstanding balances under the Unsecured Line of Credit bear interest at a per annum variable rate of Eurodollar + 0.70%. In addition, a facility fee equal to 20 basis points per annum is payable in quarterly installments. The interest rate and facility fee are subject to adjustment in the event of a change in Boston Properties Limited Partnership’s senior unsecured debt ratings. The Unsecured Line of Credit contains a competitive bid option that allows banks that are part of the lender consortium to bid to make loan advances to us at a reduced Eurodollar rate. We utilize the Unsecured Line of Credit principally to fund development of properties, land and property acquisitions, and for working capital purposes. Our Unsecured Line of Credit is a recourse obligation of Boston Properties Limited Partnership.

48

BOSTON PROPERTIES, INC.

Our ability to borrow under our unsecured revolving line of credit is subject to our compliance with a number of customary financial and other covenants on an ongoing basis, including:

• a secured debt leverage ratio not to exceed 55%;

• an unsecured loan-to-value ratio against our total borrowing base not to exceed 60%, unless our leverage ratio exceeds 60%, in which case it is not to exceed 55%;

• a debt service coverage ratio of at least 1.40 for our borrowing base properties;

• a fixed charge coverage ratio of at least 1.30 and a debt service coverage ratio of at least 1.50;

• a leverage ratio not to exceed 60%, however for five consecutive quarters (not including the two quarters prior to expiration) the leverage ratio can go to 65%;

• limitations on additional indebtedness and stockholder distributions; and

• a minimum net worth requirement.

As of September 30, 2004, we were in compliance with the financial and other covenants then applicable.

At September 30, 2004, we had letters of credit totaling $8.7 million outstanding under our Unsecured Line of Credit and no outstanding draws on our line of credit. We had the ability to borrow an additional $596.3 million under our Unsecured Line of Credit. As of November 5, 2004, we had no outstanding borrowings under our Unsecured Line of Credit.

Unsecured Senior Notes

During 2003, we issued an aggregate of $725 million of unsecured long-term debt at an average interest rate of 5.60% primarily to replace secured and unsecured variable rate debt in the following offerings:

• On January 17, 2003, we completed an unregistered offering to qualified institutional buyers in reliance on Rule 144A under the Securities Act of an additional $175 million aggregate principal amount of the Boston Properties Limited Partnership’s 6.25% senior unsecured notes due January 15, 2013. The notes were priced at 99.763% of their principal amount to yield 6.28%. The additional notes are fungible, and form a single series, with the senior notes issued in December 2002. We used the net proceeds to repay the remaining balance of our unsecured bridge loan totaling approximately $105.7 million and to repay certain construction loans maturing in 2003 totaling approximately $60.0 million.

• On March 18, 2003, we completed an unregistered offering to qualified institutional buyers in reliance on Rule 144A under the Securities Act of $300 million in aggregate principal amount of the Boston Properties Limited Partnership’s 5.625% senior unsecured notes due April 15, 2015. The notes were priced at 99.898% of their principal amount to yield 5.636%. We used the net proceeds to refinance the mortgage debt on Five Times Square and for other general business purposes.

• On May 22, 2003, we completed an unregistered offering to qualified institutional buyers in reliance on Rule 144A under the Securities Act of $250 million in aggregate principal amount of the Boston Properties Limited Partnership’s 5.0% senior unsecured notes due June 1, 2015. The notes were priced at 99.329% of their principal amount to yield 5.075%. We used the net proceeds to repay the mortgage loan secured by the property at 2600 Tower Oaks Boulevard in Maryland, repay in full amounts outstanding under the unsecured line of credit and for other general business purposes.

In December 2002, we completed an unregistered offering of $750 million in aggregate principal amount of the Boston Properties Limited Partnership’s 6.25% senior unsecured notes due January 15, 2013. The notes were only offered to qualified institutional buyers in the United States in reliance on Rule 144A under the Securities

49

BOSTON PROPERTIES, INC.

Act and to certain institutional investors outside of the United States in reliance on Regulation S under the Securities Act. The notes were priced at 99.65% of their principal amount to yield 6.296%. We used the net proceeds to reduce the amounts outstanding under our unsecured bridge loan that were borrowed in connection with the acquisition of 399 Park Avenue.

Our unsecured senior notes are redeemable at our option, in whole or in part, at a redemption price equal to the greater of (i) 100% of their principal amount or (ii) the sum of the present value of the remaining scheduled payments of principal and interest discounted at a rate equal to the yield on U.S. Treasury securities with a comparable maturity plus 35 basis points, in each case plus accrued and unpaid interest to the redemption date. The indenture under which our senior unsecured notes were issued contains restrictions on incurring debt and using our assets as security in other financing transactions and other customary financial and other covenants, including (1) a leverage ratio not to exceed 60%, (2) a secured debt leverage ratio not to exceed 50%, (3) an interest coverage ratio of 1.5, and (4) unencumbered asset value to be no less than 150% of our unsecured debt. As of September 30, 2004 we were in compliance with each of these financial restrictions and requirements.

Under registration rights agreements with the initial purchasers of our senior unsecured notes, we agreed to use our reasonable best efforts to register with the SEC offers to exchange new notes issued by us, which we refer to as “exchange notes,” for the original notes. We closed the exchange offers relating to the 6.25% senior unsecured notes due January 15, 2013 on June 20, 2003, and we closed the exchange offer relating to the 5.625% senior unsecured notes due April 15, 2015 and 5.00% senior unsecured notes due June 1, 2015 on September 9, 2003. The exchange notes are in the same aggregate principal amount as and have terms substantially identical to the original notes, but the exchange notes are freely tradable by the holders, while the original notes were subject to resale restrictions. The exchange offers did not generate any cash proceeds for us.

Off Balance Sheet Arrangements – Joint Venture Indebtedness

As of September 30, 2004, we had investments in seven unconsolidated joint ventures, of which five have mortgage indebtedness, with equity ownership ranging from 23-51%. We do not have control of these partnerships nor are we the primary beneficiary pursuant to FIN 46 and, therefore, we account for them using the equity method of accounting. At September 30, 2004, our proportionate share of the debt related to these investments was equal to approximately $161.4 million. The table below summarizes the outstanding debt (based on our respective ownership interests) in these joint venture properties at September 30, 2004.

Properties	Interest Rate		Principal Amount		Maturity Date

(4) Our joint venture partner and we have agreed to guarantee up to $7.5 million and $22.5 million, respectively, of the loan on behalf of the joint venture entity. The amounts guaranteed are subject to decrease (and elimination) upon satisfaction of certain operating performance and financial measures. In the

52

BOSTON PROPERTIES, INC.

event our partner’s guarantee is unenforceable, we have agreed to satisfy such partner’s guarantee obligations. Our partner has agreed to reimburse us for any amounts we pay in satisfaction of its guarantee obligations.

(5) In accordance with EITF 98-1, the principal amount shown was adjusted to reflect the fair value of the note using an effective interest rate of 4.38% per annum. This note is non-interest bearing and the weighted average rates exclude the impact of this note.

(6) We have agreed, together with the other third-party joint venture partners to guarantee the seller financing on behalf of the land and infrastructure entity

State and Local Tax Matters

Because we are organized and qualify as a REIT, we are generally not subject to federal income taxes, but subject to certain state and local taxes. In the normal course of business, certain entities through which we own real estate either have undergone, or are currently undergoing, tax audit. Although we believe that we have substantial arguments in favor of our positions in the ongoing audits, in some instances there is no controlling precedent or interpretive guidance on the specific point at issue. Collectively, tax deficiency notices received to date from the jurisdictions conducting the ongoing audits have not been material. However, there can be no assurance that future audits will not occur with increased frequency or that the ultimate result of such audits will not have a material adverse effect on our results of operations.

Insurance

We carry insurance coverage on our properties of types and in amounts that we believe are in line with coverage customarily obtained by owners of similar properties. In response to the uncertainty in the insurance market following the terrorist attacks of September 11, 2001, the Federal Terrorism Risk Insurance Act, or TRIA, was enacted in November 2002 to require regulated insurers to make available coverage for certified acts of terrorism (as defined by the statute) through December 31, 2004, which date was extended to December 31, 2005 by the United States Department of Treasury on June 18, 2004. TRIA expires on December 31, 2005, and we cannot currently anticipate whether it will be extended. Our property insurance program provides a $640 million per occurrence limit, including coverage for “certified acts of terrorism” as defined by TRIA. Additionally, the program provides $615 million of coverage for acts of terrorism other than those “certified” under TRIA. We also carry nuclear, biological and chemical terrorism insurance coverage with a $640 million per occurrence limit for “certified acts of terrorism” as defined by TRIA, which is provided by IXP, Inc. as a direct insurer. Under TRIA, this nuclear, biological and chemical terrorism insurance coverage is backstopped by the Federal Government after the payment of the required deductible and 10% coinsurance.

We also carry earthquake insurance on our properties located in areas known to be subject to earthquakes in an amount and subject to deductibles and self-insurance that we believe are commercially reasonable. Specifically, we carry earthquake insurance which covers our San Francisco portfolio with a $120 million per occurrence limit and a $120 million aggregate limit, $20 million of which is provided by IXP, Inc., as a direct insurer. The amount of our earthquake insurance coverage may not be sufficient to cover losses from earthquakes. As a result of increased costs of coverage and decreased availability, the amount of third-party earthquake insurance that we may be able to purchase on commercially reasonable terms may be reduced. In addition, we may discontinue earthquake insurance on some or all of our properties in the future if the premiums exceed our estimation of the value of the coverage.

In January 2002, we formed a wholly-owned taxable REIT subsidiary, IXP, Inc., or IXP, to act as a captive insurance company and be one of the elements of our overall insurance program. IXP acts as a direct insurer with respect to a portion of our earthquake insurance coverage for our Greater San Francisco properties and our nuclear, biological and chemical terrorism insurance coverage for “certified acts of terrorism” under TRIA. Insofar as we own IXP, we are responsible for its liquidity and capital resources, and the accounts of IXP are part

53

BOSTON PROPERTIES, INC.

of our consolidated financial statements. If we experience a loss and IXP is required to pay under its insurance policy, we would ultimately record the loss to the extent of IXP’s required payment. Therefore, insurance coverage provided by IXP should not be considered as the equivalent of third-party insurance, but rather as a modified form of self-insurance.

We continue to monitor the state of the insurance market in general, and the scope and costs of coverage for acts of terrorism in particular, but we cannot anticipate what coverage will be available on commercially reasonable terms in future policy years. There are other types of losses, such as from wars, acts of nuclear, biological or chemical terrorism other than those “certified” under TRIA, or the presence of mold at our properties, for which we cannot obtain insurance at all or at a reasonable cost. With respect to such losses and losses from acts of terrorism, earthquakes or other catastrophic events, if we experience a loss that is uninsured or that exceeds policy limits, we could lose the capital invested in the damaged properties, as well as the anticipated future revenues from those properties. Depending on the specific circumstances of each affected property, it is possible that we could be liable for mortgage indebtedness or other obligations related to the property. Any such loss could materially and adversely affect our business and financial condition and results of operations.

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) (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. In addition to presenting FFO in accordance with the NAREIT definition, we also disclose FFO after specific and defined supplemental adjustments, including gains or losses on derivative instruments, consisting of changes in fair value and periodic cash settlements that do not qualify for hedge accounting pursuant to the provisions of SFAS No. 133 (“non-qualifying derivative contracts”). As the impact of the non-qualifying derivative contracts did not extend beyond the quarter ended September 30, 2003, FFO as adjusted for periods ended on and after December 31, 2003 is the same as FFO computed in accordance with the NAREIT definition.

The adjustments for non-qualifying derivative contracts resulted from interest rate contracts we entered into prior to the effective date of SFAS No. 133 to limit our exposure to fluctuations in interest rates with respect to variable rate debt associated with real estate projects under development. Upon transition to SFAS No. 133 on January 1, 2001, the impacts of these contracts were recorded in current earnings, while prior to that time they were capitalized. Although these adjustments are attributable to a single hedging program, the underlying contracts extended over multiple reporting periods and therefore resulted in adjustments from the first quarter of 2001 through the third quarter of 2003. Management presents FFO before the impact of non-qualifying derivative contracts because economically this interest rate hedging program was consistent with our risk management

54

BOSTON PROPERTIES, INC.

objective of limiting our exposure to interest rate volatility and the change in accounting under GAAP did not correspond to a substantive difference. Management does not currently anticipate structuring future hedging programs in a manner that would give rise to this kind of adjustment.

Management uses FFO principally to evaluate the operating performance of our assets from period to period, and therefore it is important that transactions which impact operations over multiple periods be reflected in FFO in accordance with their substance, even if GAAP requires that the income or loss attributable to the transaction be recorded in a particular period. The resulting adjustments to FFO computed in accordance with the NAREIT definition are particularly meaningful when the events in question are substantively equivalent to other similar transactions, but the reporting of those similar transactions under GAAP more closely matches their economic substance.

Although our FFO as adjusted clearly differs from NAREIT’s definition of FFO, as well as that of other REITs and real estate companies, we believe it provides a meaningful supplemental measure of our operating performance because we believe that, by excluding the effects of the non-qualifying derivative contracts, management and investors are presented with an indicator of our operating performance that more closely achieves the objectives of the real estate industry in presenting FFO. Additionally, we believe the nature of these adjustments is non-recurring because there were not similar events during the two preceding years, and the events were not reasonably likely to recur and did not, in fact, recur within the succeeding two years. Neither FFO nor FFO as adjusted should be considered as alternatives to net income (determined in accordance with GAAP) as an indication of our performance.

Neither FFO nor FFO as adjusted represents 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 and FFO as adjusted should be compared with our reported net income and considered in addition to cash flows in accordance with GAAP, as presented in our consolidated financial statements.

Contractual Obligations

On July 30, 2004, we entered into a lease with Lockheed Martin Corporation (LMC) totaling approximately 182,000 square feet related to the development of a build-to-suit office building in Reston, Virginia. LMC currently leases more than 500,000 square feet in two buildings within the same office complex. We expect to invest a total of $45.8 million and we expect to complete the building in the second quarter of 2006.

On August 2, 2004, we entered into joint ventures with unrelated third parties to pursue the development of a Class A office building totaling approximately 305,000 square feet and retail space that will be part of a mixed-use development of office, retail and residential properties known as Wisconsin Place located in Chevy Chase, Maryland. The new development will sit above a shared four-story parking garage with over 1,700 parking spaces. We have a 66.67% interest in the joint venture entity that will develop and own the office building component of the project (the “Office Entity”). We have a 5.0% interest in the joint venture entity that will develop and own the retail component of the project (the “Retail Entity”). We have accounted for our investment in the Retail Entity under the equity method of accounting. We do not have an ownership interest in the entity that will develop and own the residential component of the project (the “Residential Entity”). The Office Entity, Retail Entity and Residential Entity each own a 33.33% interest in the entity owning and developing the land and infrastructure components of the project (the “Land and Infrastructure Entity”). The Land and Infrastructure Entity acquired the land for a purchase price of $23.5 million from an unrelated third party and obtained seller financing totaling $23.5 million. The seller financing is non-interest bearing and matures in February 2008. The Land and Infrastructure Entity has recorded the seller financing at its fair value of approximately $21.2 million using an effective interest rate of 4.38% per annum. The Operating Partnership, with the other third-party joint venture partners, has agreed to guarantee the seller financing on behalf of the Land and Infrastructure Entity. We expect to invest approximately $25.7 million in this project.

BOSTON PROPERTIES, INC.

In September 2004, we commenced the redevelopment of our Capital Gallery property in Washington, D.C. Capital Gallery is a Class A office property totaling approximately 397,000 square feet. The project entails removing a three-story low-rise section of the property comprised of 100,000 square feet from in-service status and redeveloping it into a 10-story office building resulting in a total complex size of approximately 610,000 square feet upon completion. The redevelopment cost is estimated at approximately $69.1 million and is expected to be completed by the end of 2005.

We have various standing or renewable service contracts with vendors related to our property management. In addition, we have certain other utility contracts we enter into in the ordinary course of business which may extend beyond one year, which vary based on usage. These contracts include terms that provide for cancellation with insignificant or no cancellation penalties. Contract terms are generally one year or less.

Newly Issued Accounting Standards

In March 2004, the Emerging Issues Task Force reached a final consensus regarding Issue 03-6, “Participating Securities and the Two-Class Method under FAS 128.” The issue addresses a number of questions regarding the computation of earnings per share by companies that have issued securities other than common stock that participate in dividends and earnings of the issuing entity. Such securities are contractually entitled to receive dividends when and if the entity declares dividends on common stock. The issue also provides further guidance on applying the two-class method of calculating earnings per share once it is determined that a security is participating. The two-class method is an earnings allocation formula that determines earnings per share for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. This consensus was effective for the period ended June 30, 2004 and was applied by restating previously reported earnings per share. We have adopted the provisions of EITF 03-6, and have determined that the Series Two Preferred Units of our Operating Partnership constitute a participating security. The adoption of EITF 03-6 has resulted in a reduction of our earnings per share for those periods in which the Operating Partnership had undistributed earnings. Undistributed earnings were allocated to the Series Two Preferred Units based on their contractual rights to share in those earnings as if all the earnings for the period had been distributed.

ITEM 3 – Quantitative and Qualitative Disclosures about Market Risk

Approximately $4.6 billion of our borrowings bear interest at fixed rates, and therefore the fair value of these instruments is affected by changes in the market interest rates. The following table presents our aggregate fixed rate debt obligations with corresponding weighted-average interest rates sorted by maturity date and our aggregate variable rate debt obligations sorted by maturity date. The interest rate on the variable rate debt as of September 30, 2004 ranged from LIBOR/Eurodollar plus 0.90% to LIBOR/Eurodollar plus 1.00%.

(1) Assumes exercise of one-year extension option with respect to approximately $214,900 of currently outstanding indebtedness that otherwise would mature in 2006 under the Times Square Tower construction loan facility. This extension option is contingent only upon the payment of an extension fee and the loan not being in default and is subject to no other performance criteria.

We had a derivative contract for a notional amount of $150 million prior to the modification described below. The derivative contract provided for a fixed interest rate of 6.35% when LIBOR is less than 5.80%, 6.70% when LIBOR is between 6.70% and 7.45%, and 7.50% when LIBOR is between 7.51% and 9.00% through February 2005. In August 2003, we modified the contract to provide for the counter party to pay us LIBOR and we are required to pay the counter party LIBOR + 4.55% on a notional amount of $150 million. The derivative contract expires in February 2005. In accordance with SFAS No.133, the derivative agreement is reflected at its fair market value, which was a liability of $2.9 million at September 30, 2004.

At September 30, 2004, our variable rate debt outstanding was approximately $416 million. At September 30, 2004, the average interest rate on variable rate debt was approximately 2.78%. If market interest rates on our variable rate debt had been 100 basis points greater, total interest expense would have increased approximately $1.4 million for the three months ended September 30, 2004.

At September 30, 2003, our variable rate debt outstanding was approximately $342 million. At September 30, 2003, the average interest rate on variable rate debt was approximately 3.02%. If market interest rates on our variable rate debt had been 100 basis points greater, total interest expense would have increased approximately $1.0 million for the three months ended September 30, 2003.

ITEM 4 – Controls and Procedures
