BOSTON PROPERTIES LIMITED PARTNERSHIP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization

Boston Properties Limited Partnership (the “Company”), a Delaware limited partnership, is the entity through which Boston Properties, Inc., a self-administered and self-managed real estate investment trust (“REIT”), conducts substantially all of its business and owns (either directly or through subsidiaries) substantially all of its assets. Boston Properties, Inc. is the sole general partner of the Company and at June 30, 2004 owned an approximate 79.6% (76.6% at June 30, 2003) general and limited partnership interest in the Company. Partnership interests in the Company 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 Boston Properties, Inc. A holder of an OP Unit may present such OP Unit to the Company 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 Company must redeem such OP Unit for cash equal to the then value of a share of common stock of Boston Properties, Inc. (“Common Stock”). In lieu of a cash redemption, Boston Properties, Inc. 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 Boston Properties, Inc. 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 stock of Boston Properties, Inc. 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 13).

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

All references to the Company refer to Boston Properties Limited Partnership and its subsidiaries, collectively, unless the context otherwise requires.

The Properties:

At June 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 June 30, 2003, respectively) (the “Properties”) aggregating approximately 43.6 million net rentable square feet (approximately 43.9 million and 42.9 million net rentable square feet at December 31, 2003 and June 30, 2003, respectively), including three properties under construction totaling approximately 2.0 million net rentable square feet. During the three months ended June 30, 2004, the Company sold three Class A office properties and one industrial property aggregating approximately 411,000 net rentable square feet. At June 30, 2004, the Properties consist of:

•

119 office properties comprised of 101 Class A office properties (including three properties under construction) and 18 office/technical properties;

•

two industrial properties;

•

three hotels; and

•

two retail properties.

BOSTON PROPERTIES LIMITED PARTNERSHIP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

In addition, the Company owns or controls land parcels totaling approximately 548.0 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 Company, nor does it have employees of its own. The Company, 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 another 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 did not have 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 June 30, 2004, Boston Properties, Inc. has stock-based employee compensation plans. In 2003, Boston Properties, Inc. 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.

BOSTON PROPERTIES LIMITED PARTNERSHIP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

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 unitholders and earnings per common unit 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.

Reclassifications

3. Real Estate Activity During the Six Months Ended June 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 Boston Properties Inc.’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.

Dispositions

On January 16, 2004, the Company sold 430 Rozzi Place, an industrial property totaling 20,000 net rentable square feet located in South San Francisco, California for net cash proceeds of approximately $2.4 million, resulting in a gain on sale of approximately $0.7 million (net of minority interest share of approximately $1.5 million). The Company had a 35.7% interest in this property, which was consolidated in the Company’s financial statements due to the Company’s unilateral control. This property has been categorized as discontinued operations in the accompanying Consolidated Statements of Operations.

On February 4, 2004, the Company sold Hilltop Office Center, comprised of nine office/technical properties totaling approximately 143,000 net rentable square feet located in South San Francisco, California for net cash proceeds of approximately $11.6 million and the assumption by the buyer of the mortgage debt on the properties totaling $5.2 million, resulting in a gain on sale of approximately $8.2 million (net of minority interest share of approximately $7.3 million). The Company had a 35.7% interest in these properties, which were consolidated in the Company’s financial statements due to the Company’s unilateral control. Due to the Company’s continuing involvement in the management of the properties after the sale, the Company has not categorized these properties as discontinued operations in the accompanying Consolidated Statements of Operations.

On February 10, 2004, the Company sold Sugarland Business Park—Building Two, an office/technical property totaling 59,000 net rentable square feet located in Herndon, Virginia for net cash proceeds of approximately $6.8 million, resulting in a gain on sale of approximately $2.4 million. This property has been categorized as discontinued operations in the accompanying Consolidated Statements of Operations.

On April 1, 2004, the Company sold Decoverly Two, Three, Six and Seven, located in Rockville, Maryland, for aggregate net cash proceeds of $41.2 million, resulting in a gain on sale of approximately $11.5 million. The properties consist of two Class A office properties totaling approximately 155,000 square feet and two land parcels, one of which is subject to a ground lease. In addition, on April 1, 2004, the Company sold The Arboretum, a Class A office property totaling approximately 96,000 square feet located in Reston, Virginia, for net cash proceeds of $21.1 million, resulting in a gain on sale of approximately $8.1 million. These properties have been categorized as discontinued operations in the accompanying Consolidated Statements of Operations.

On May 21, 2004, the Company sold 38 Cabot Boulevard, an industrial property totaling 161,000 net rentable square feet located in Langhorne, Pennsylvania for net cash proceeds of approximately $5.5 million, resulting in a gain on sale of approximately $4.3 million. This property has been categorized as discontinued operations in the accompanying Consolidated Statements of Operations.

On June 10, 2004, the Company sold a parcel of land at Burlington Mall Road located in Burlington, Massachusetts for net cash proceeds of approximately $1.9 million, resulting in a gain on sale of approximately $1.7 million. This property has not been categorized as discontinued operations in the accompanying Consolidated Statements of Operations.

Other

On January 30, 2004, a third party terminated an agreement to enter into a ground lease with the Company, and in connection therewith the Company subsequently received consideration of approximately $7.5 million. Because the Company has no further obligations under this agreement, such amount is reflected within revenue as interest and other in the Consolidated Statements of Operations for the six months ended June 30, 2004.

BOSTON PROPERTIES LIMITED PARTNERSHIP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

In addition, the Company and its joint venture partner in BP/CRF 901 New York Avenue LLC have agreed to guarantee up to $7.5 million and $22.5 million, respectively, of the construction loan on behalf of BP/CRF 901 New York Avenue LLC. 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.

(2)

This amount represents the aggregate difference between the Company’s historical cost basis reflected and the basis reflected at the joint venture level, which is typically amortized over the life of the related asset. Basis differentials occur primarily upon the transfer of assets that were previously owned by the Company into a joint venture. In addition, certain acquisition, transaction and other costs may not be reflected in the net assets at the joint venture level.

The combined summarized statements of operations of the joint ventures are as follows:

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 loan bore interest at LIBOR + 1.95% per annum and was scheduled to mature in November 2004. This loan facility totaling $475.0 million 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 June 30, 2004, the outstanding balance under the loan facility was $389.9 million. The loan facility involves a syndication of lenders. Accordingly, for those lenders that participated in both the original loan and the refinancing, the initial direct debt issuance costs, as well as the costs incurred with the refinancing are being amortized over the term of the loan, as the refinancing was not significant pursuant to the provisions of EITF 96-19. 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

BOSTON PROPERTIES LIMITED PARTNERSHIP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

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, 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.

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.

6. Unsecured Line of Credit

The Company has a $605.0 million unsecured revolving credit facility (the “Unsecured Line of Credit”) with a three year term expiring on January 17, 2006 with a provision for a one year extension at the option of the Company, 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 the Company’s 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 the Company at a reduced Eurodollar rate. At June 30, 2004, there were no amounts outstanding under the Unsecured Line of Credit.

The terms of the Unsecured Line of Credit require that the Company maintain a number of customary financial and other covenants on an ongoing basis, including: (1) a secured debt leverage ratio not to exceed 55%, (2) 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%, (3) a debt service coverage ratio of at least 1.40 for our borrowing base properties, (4) a fixed charge coverage ratio of at least 1.30 and a debt service coverage ratio of at least 1.50, (5) 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%, (6) limitations on additional indebtedness and stockholder distributions, and (7) a minimum net worth requirement. As of June 30, 2004, the Company was in compliance with each of these financial and other covenant requirements.

7. Commitments and Contingencies

General

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

BOSTON PROPERTIES LIMITED PARTNERSHIP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The Company has letter of credit and performance obligations of approximately $16.5 million related to lender and development requirements.

At June 30, 2004, the Company had a guarantee obligation outstanding with a lender totaling approximately $1.4 million related to the re-tenanting of an unconsolidated joint venture property. The amounts guaranteed are subject to decrease (and elimination) upon the satisfaction of certain operating performance and financial measures.

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.

The Company’s joint venture agreements generally include provisions whereby 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.

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 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

BOSTON PROPERTIES LIMITED PARTNERSHIP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

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.

8. Redeemable Partnership Units

As of June 30, 2004, the redeemable partnership units consisted of 21,876,480 OP Units, 169,838 LTIP Units and 4,330,225 Series Two Preferred Units (or 5,682,714 OP Units on an as converted basis).

On May 4, 2004, 1,070,437 Series Two Preferred Units of the Company were converted by the holders into 1,404,772 OP Units. The OP Units were subsequently presented by the holders for redemption and were redeemed by Boston Properties, Inc. in exchange for an equal number of shares of Common Stock. 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 Company had 4,330,225 Series Two Preferred Units outstanding as of June 30, 2004.

On May 5, 2004, Boston Properties, Inc., as general partner of the Company, declared a distribution on the OP Units in the amount of $0.65 per OP Unit payable on July 30, 2004 to OP Unitholders of record on June 30, 2004.

On May 17, 2004, the Company paid a distribution on its outstanding Series Two Preferred Units of $0.85342 per unit.

Due to the redemption option and the conversion option existing outside the control of the Company, such OP Units and Preferred Units are not included in Partners’ Capital and are reflected in the consolidated balance sheets at an amount equivalent to the value of such units had such units been redeemed at June 30, 2004 and December 31, 2003, respectively. Included in preferred distributions in the consolidated statements of operations is accretion of approximately $1.1 million and $1.2 million for the six months ended June 30, 2004 and 2003, respectively, and $0.5 million and $0.6 million for the three months ended June 30, 2004 and 2003, respectively, which represents the accretion of Preferred Units from the value of the units at issuance to the liquidation value.

9. Partners’ Capital

As of June 30, 2004, Boston Properties, Inc. owned 1,302,068 general partner units and 106,858,419 limited partner units.

BOSTON PROPERTIES LIMITED PARTNERSHIP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

On March 3, 2004, Boston Properties, Inc. 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. Boston Properties, Inc. contributed the proceeds of the offering to the Company in exchange for 5,700,000 common units.

On May 5, 2004, Boston Properties, Inc., as general partner of the Company, declared a distribution in the amount of $0.65 per share of common unit payable on July 30, 2004 to unitholders of record as of the close of business on June 30, 2004.

10. Losses from Early Extinguishments of Debt

During the six months ended June 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.

11. 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 six months ended June 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 six months ended June 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;

(2) Sugarland Business Park—Building Two, an office/technical property totaling approximately 59,000 net rentable square feet located in Herndon, Virginia;

(3) Decoverly Two, Three, Six and Seven, consisting of Two Class A office properties totaling approximately 155,000 net rentable square feet and two land parcels, one of which is subject to a ground lease, located in Rockville, Maryland;

(4) The Arboretum, a Class A office property totaling approximately 96,000 net rentable square feet located in Reston, Virginia; and

(5) 38 Cabot Boulevard, an industrial property totaling approximately 161,000 net rentable square feet located in Langhorne, Pennsylvania.

In addition, at June 30, 2004, the Company had designated as held for sale Sugarland Business Park—Building One, an office/technical property totaling approximately 52,000 net rentable square feet located in Herndon, Virginia. The Company has presented the properties discussed above as discontinued operations in its Consolidated Statements of Operations for the three months and six months ended June 30, 2004 and 2003. In addition, the Company sold 2300 N Street, a Class A office property totaling approximately 289,000 net rentable

BOSTON PROPERTIES LIMITED PARTNERSHIP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

square feet located in Washington, D.C. during the six months ended June 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 six months ended June 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 $8.2 million (net of minority interest share of approximately $7.3 million) and 2300 N Street in Washington, D.C., totaling approximately $64.7 million, have been reflected as “Gains on sales of real estate and other assets” in the Consolidated Statements of Operations for the six months ended June 30, 2004 and 2003, respectively.

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

At June 30, 2004, the Company had designated as held for sale Sugarland Business Park—Building One, an office/technical property totaling approximately 52,000 net rentable square feet located in Herndon, Virginia. The anticipated sales price exceeds the carrying value at June 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 $27.0 million (net of minority interest share of approximately $1.5 million) and $91.9 million to be reflected as “Gains on sales of real estate from discontinued operations” in the accompanying Consolidated Statements of Operations for the six months ended June 30, 2004 and 2003, respectively. The application of SFAS No. 144 does not have an impact on net income available to common unitholders. SFAS No. 144 only impacts the presentation of these properties within the Consolidated Statements of Operations.

12. Earnings Per Common Unit

Earnings per common unit have 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 units used in the computation of basic earnings per common unit, which is calculated by dividing net income available to common unitholders by the weighted-average number of common units outstanding during the period. During the period ended June

BOSTON PROPERTIES LIMITED PARTNERSHIP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

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. EITF 03-6 requires that each period’s undistributed earnings be allocated to participating securities based on their contractual rights to share in those earnings as if all the earnings for the period had been distributed. Accordingly, for the reporting periods in which the Company’s net income is in excess of common and preferred distributions, such income is allocated to the common and Series Two Preferred Units in proportion to their respective interests. During reporting periods in which net income is less than the distributions paid on the common units and Series Two Preferred Units, such deficiency is allocated entirely to the common units. Prior periods have been restated to conform to the provisions of EITF 03-6. For the three and six months ended June 30, 2004 and 2003, approximately $900,000 and $0, $1,100,000 and $8,600,000, respectively, were allocated to the Series Two Preferred Units in excess of distributions and are included in preferred distributions and allocation of undistributed earnings. Other potentially dilutive common units, and the related impact on earnings, are considered when calculating diluted earnings per common unit.

13. Stock Option and Incentive Plan

During the six months ended June 30, 2004, Boston Properties, Inc., as general partner of the Company, issued 31,695 shares of restricted stock valued at approximately $1.6 million and 166,430 LTIP Units valued at approximately $8.4 million. An LTIP Unit is generally the economic equivalent of a share of restricted stock in Boston Properties, Inc. The aggregate value of the LTIP Units is not included in “Unearned compensation” in the Consolidated Balance Sheets as it is reflected in “Redeemable partnership units.” 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 Boston Properties, Inc.’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 $0.9 million and $0.7 million during the three months ended June 30, 2004 and 2003, respectively and $2.2 million and $1.1 million during the six months ended June 30, 2004 and 2003, respectively.

14. 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 unitholders, the most directly comparable GAAP financial measure, plus preferred distributions, 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, income from discontinued operations, gains on sales of real estate and other assets, 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 or real estate companies 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.

15. 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 its Series Two Preferred Units constitutes a participating security. The adoption of EITF 03-6 has resulted in a reduction of net income available to common unit holders for those periods in which the Company 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.

16. Subsequent Events

In July 2004, the Company 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. The Company has 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.

On July 30,2004, the Company entered into a lease with the Lockheed Martin Corporation (LMC) totaling approximately 182,000 square feet for the development of a building in Reston, Virginia. This building will become part of an existing complex where LMC already leases from the Company over 500,000 square feet in two buildings.

On August 1, 2004, the Company completed the sale of Sugarland Business Park—Building One, an office/technical property totaling approximately 52,000 square feet located in Herndon, Virginia for approximately $7.8 million.

On August 2, 2004, the Company entered into a joint venture with unaffiliated 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 called Wisconsin Place located in Chevy Chase, Maryland. The new development will sit on top of a shared 4-story parking garage with over 1,700 parking spaces. The Company will own a 66.67% interest in the office building.

On August 3, 2004, the Company entered into a lease with Ann Taylor Stores Corporation totaling approximately 300,000 square feet at Times Square Tower in New York City.

ITEM 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with the financial statements and notes thereto appearing elsewhere in this report. This Report on Form 10-Q contains forward-looking statements within the meaning of the federal securities laws. We caution investors that any forward-looking statements presented in this report, or which management may make orally or in writing from time to time, are based on management’s beliefs and assumptions made by, and information currently available to, management. When used, the words “anticipate,” “believe, “ “expect,” “intend,” “may,” “might,” “plan,” “estimate,” “project,” “should,” “will,” “result” and similar expressions which do not relate solely to historical matters are intended to identify forward-looking statements. Such statements are subject to risks, uncertainties and assumptions and are not guarantees of future performance, 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 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 the potential failure of Boston Properties, Inc. 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 recent 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 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

Boston Properties Limited Partnership is the entity through which Boston Properties, Inc., 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 conducts substantially all of its business and owns (either directly or through subsidiaries) substantially all of its assets. 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 US economy has experienced continued economic growth. In the second quarter of 2004, leasing activity and lease economics improved in New York City, Northern Virginia and Washington, D.C.; however, office leasing conditions in the Boston central business district, Boston suburbs and Montgomery County, Maryland have yet to demonstrate much change. In addition, during the second quarter, the Boston area hotels began to show improvement in terms of both occupancy and daily rates. It is too early for these improvements to have a significant impact our top-line revenue, Same Property results or property revenue statistics, and the improvement does not include all our markets. 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 and by solidifying our capital structure through the refinancing of a significant portion of our variable rate debt with long-term, fixed-rate debt and the issuance of common equity. Our variable rate debt now consists almost entirely of our construction loans on Times Square Tower and New Dominion Two. Accordingly, our exposure to potentially greater costs associated with rising interest rates has been reduced. We are also marketing select assets and we completed four sales in the second quarter of 2004. We are constantly reviewing our portfolio to identify potential asset acquisitions, opportunities for development and asset dispositions. As a result of Boston Properties, Inc.’s recently completed public equity offering and completed and expected sales of assets, we believe we are well-positioned and have the capacity with which to finance new acquisitions and developments.

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

•

We increased the quarterly dividend payable to holders of Boston Properties, Inc.’s common stock from $0.63 per share to $0.65 per share. This represents a 3.2% increase.

•

We sold the following four non-core buildings aggregating approximately 411,000 square feet and three land parcels (one of which is subject to a ground lease):


Date	Property	Gross Sales Price
4/1/04	Decoverly Two, Three, Six, and Seven located in Rockville, Maryland (two Class A office properties and two land parcels)	$42.0 million
4/1/04	The Arboretum located in Reston, Virginia (one Class A office property)	$21.5 million
5/21/04	38 Cabot Boulevard located in Langhorne, Pennsylvania (one industrial building)	$5.8 million
6/10/04	Burlington Mall Road located in Burlington, Massachusetts (one land parcel)	$1.9 million

•

On April 1, 2004, we 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, we 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 secured 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 Boston Properties, Inc.’s public offering of its common stock in March, 2004. The property is 99% leased.

•

On April 26, 2004, we amended our lease with Genentech at our 611 Gateway Boulevard property in South San Francisco, California to expand into an additional 111,273 square feet with an expected commencement in December 2004. With the expansion, Genentech will occupy the entire building consisting of 256,302 square feet.

•

On May 4, 2004, 1,070,437 Series Two preferred units were converted by the holders into 1,404,772 OP Units, which OP Units were subsequently redeemed in exchange for an equal number of shares of common stock of Boston Properties, Inc.

•

On May 27, 2004, we executed a contract for the sale of 560 Forbes Boulevard, an industrial property totaling approximately 40,000 square feet located in South San Francisco, California, for $4.0 million. We have a 35.7% interest in this property. The sale is subject to the satisfaction of customary closing conditions and, although there can be no assurances that the sale will be consummated on the terms currently contemplated or at all, we expect the transaction will close by the end of November 2004.

•

On June 25, 2004, we signed a new lease with the law firm Heller, Ehrman, White & McAuliffe totaling 133,733 square feet at Times Square Tower.

Transactions completed subsequent to June 30, 2004:

•

In July 2004, we began 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. The anticipated investment for this project totals $146 million. 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 that the building will be complete and available for occupancy during the first quarter of 2006.

•

On July 30, 2004, we entered into an approximately 182,000 square foot lease with the Lockheed Martin Corporation (LMC) for the development of a building in Reston, Virginia. This building will become part of an existing complex where LMC already leases over 500,000 square feet from Boston Properties in two buildings. Construction of the project is scheduled start in the 4th Quarter of 2004 and delivery is anticipated in the 2nd Quarter of 2006.

•

On August 1, 2004, we completed our sale of Sugarland Business Park—Building One, an office/technical property totaling approximately 52,000 square feet located in Herndon, Virginia for approximately $7.8 million.

On August 2, 2004, we entered into a joint venture with unaffiliated 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 called Wisconsin Place located in Chevy Chase, Maryland. The new development will sit on top of a shared 4-story parking garage with over 1,700 parking spaces. We will own a 66.67% interest in the office building.

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, a portion of which was first placed into service in April 2004, is now approximately 74% leased.

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. 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 value; 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 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, “Accounting for the Impairment or Disposal of Long-Lived Assets,” 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. Determination of when a development project is substantially complete and capitalization must cease involves a degree of judgement. 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 as we exercise significant influence, 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 currently under development. The profit on development fees received from this joint venture 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 7.2 years as of June 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.

We record our development fees earned on real estate projects on a straight-line basis over the development period, which approximates the percentage of completion method described in AICPA Statement of Position (SOP) 81-1 and provides a more accurate measurement over the period of fees earned. 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 June 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 six and three months ended June 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 net derivative losses, depreciation and amortization, interest expense and general and administrative expense, less gains on sales of real estate from discontinued operations, income from discontinued operations, gains on sales of real estate, 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.

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 six months ended June 30, 2004 to the six months ended June 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 million square feet of office space and three hotel properties acquired or placed in-service on or prior to January 1, 2003 and owned through June 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 June 30, 2004.

BOSTON PROPERTIES LIMITED PARTNERSHIP

Rental Revenue

The increase in rental revenue of $33.4 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 $32.9 million, as detailed below:


		Revenue for the six months ended June 30,
Property	Date Acquired	2004		2003		Change
		(in thousands)
One and Two Discovery Square	April 1, 2003	$	6,601	$	2,987	$	3,614
One and Two Freedom Square	August 5, 2003		15,068		—		15,068
1333 New Hampshire Avenue	October 8, 2003		7,710		—		7,710

1330 Connecticut Avenue	April 1, 2004		3,583		—		3,583

Total Additions		$	35,876	$	2,987	$	32,889

In addition, the placing into service of (1) Shaws Supermarket in the second quarter of 2003 and (2) a portion of Times Square Tower as of April 1, 2004, increased revenue by approximately $8.0 million for the six months ended. The aggregate increase was offset by a decrease of approximately $3.6 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 property. The decrease in the remaining Same Property Portfolio reflects declining base rents of approximately $1.1 million and a decrease in straight-line rents of $2.8 million. We anticipate roll-downs in rent on our expiring leases over the foreseeable future. The impact of these roll-downs and the vacancy we assume on any lease roll-over will decrease our Same Property revenue.

Termination Income

Termination income for the six months ended June 30, 2004 was related to nine tenants across the portfolio that terminated their leases and made termination payments totaling approximately $1.4 million. This compared to termination income earned for the six months ended June 30, 2003 related to nine tenants totaling $3.2 million. We expect to recognize termination income in the third quarter of 2004 resulting from a transaction in New York City in which a tenant will pay approximately $1.0 million to cancel a lease.

Development and Management Services

Our third-party fee income decreased approximately $1.0 million for the first six months of 2004 compared to 2003, and we expect this to decrease further during 2005 with the completion of projects such as 901 New York Avenue, National Institute of Health and 90 Church Street which collectively contributed $4.3 million and $4.7 million to development and management services for the six months ended June 30, 2004 and 2003. We continue to pursue new fee-for-service projects and may be able to increase this fee business as we move into the later part of 2004 and 2005.

Interest and Other Income

Interest and other income increased by $7.5 million in the Total Portfolio for the six months ended June 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 second quarter we had a cash balance of approximately $228 million. To the extent we don’t acquire any properties or fund new developments, we anticipate interest will increase 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 $9.5 million. Approximately $7.2 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. This increase was offset by a decrease of an aggregate of $1.0 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 property. In addition, the placing into service of (1) Shaws Supermarket in 2003 and (2) a portion of Times Square Tower as of April 1, 2004, increased operating expenses approximately $1.0 million for the six months ended June 30, 2004. The remaining increases are due to the overall increase in Same Property Portfolio operating expenses of $2.3 million, the majority of which is due to an increase in real estate tax assessment for our properties in New York City.

Hotel Net Operating Income

Net operating income for the hotel properties increased by approximately $0.3 million or approximately 3.69% for the six months ended June 30, 2004 compared to the six months ended June 30, 2003. The hotel properties have shown a strong second quarter, revenue per available room (REVPAR,) met our expectations for the first time in two years. The following reflects our occupancy and rate information for the three hotel properties for the six months ended June 30, 2004 and 2003:


	2004			2003			Increase (Decrease)
Occupancy		79.1	%		74.0	%	6.9	%
Average daily rate	$	162.50		$	161.12		0.9	%
Revenue per available room, REVPAR	$	129.03		$	119.46		8.0	%

Other Expenses

General and Administrative

General and administrative expenses in the Total Portfolio increased during the six months ended June 30, 2004 as compared to the six months ended June 30, 2003 by $2.7 million or 11.89%. An aggregate of $1.0 million of the increase is attributable to changes in the form of long-term equity-based compensation, as further described below. The remaining increase is due to compensation expense increases during 2004.

stock vests over a five-year vesting period. Stock-based compensation associated with approximately $9.7 million of restricted stock granted by Boston Properties Inc. 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 the Board of Directors of Boston Properties, Inc. continues its 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 higher costs 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 remained the same. Our floating rate debt now consists almost entirely of our construction loans on Times Square Tower and New Dominion Two. Despite increases in short-term market interest rates from June 30, 2003 to 2004, our weighted average rate on variable rate debt has decreased primarily as a result of refinancing of Times Square Tower debt in January 2004. We are exploring alternatives to permanently finance our New Dominion Two building which was placed into service in July 2004. Our total debt outstanding at June 30, 2004 was approximately $5.0 billion compared to $4.8 billion at June 30, 2003. The following summarizes our debt outstanding as of June 30, 2004 compared with 2003.

Variable rate		2.28	%		2.95	%

Total		6.28	%		6.50	%

Depreciation and Amortization

Depreciation and amortization expense for the Total Portfolio increased as a result of the addition of One and Two Discovery Square, One and Two Freedom Square, 1333 New Hampshire Avenue, 140 Kendrick Street and 1330 Connecticut, which collectively represented an aggregate of $8.1 million of the increase. Increases in Same Property Portfolio represented $7.0 million.

Costs directly related to the development of rental properties are capitalized. Capitalized development costs include interest, wages, property taxes, insurance and other project costs incurred during the period of development. Capitalized wages for the six months ended June 30, 2004 and 2003 were $2.9 million and $2.5 million, respectively. These costs are not included in the general and administrative expenses discussed above. Interest capitalized for the six months ended June 30, 2004 and 2003 was $8.4 million and $9.1 million, respectively. These costs are not included in the interest expense referenced above. During the three months ended June 30, 2004 we placed a portion of Times Square Tower into service. As we continue to place this building into service, the capitalized costs will decrease and depreciation and amortization expense will increase.

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 $4.8 million at June 30, 2004, is included on our balance sheets. As a result of our contract modification 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 Revenue as of March 24, 2004. One and Two Discovery Square are included in the Total Portfolio Revenue as of April 1, 2003. One and Two Freedom Square are included in the Total Portfolio Revenue as of August 5, 2003. The reclassification of these properties caused the overall income from unconsolidated joint ventures to decrease $2.6 million offset by an increase in the remaining joint ventures included in Same Property of $1.0 million.

Other

The decrease in income from discontinued operations in the Total Portfolio for the six months ended June 30, 2004 was a result of properties being sold during the first quarter of 2003 and 2004. We did not recognize a full quarter of revenue and expenses with respect to these properties. Included in the six months ended June 30, 2004 is six months of Sugarland Business Park, Building One, one quarter of The Arboretum, Decoverly Two, Three and Seven and 38 Cabot Boulevard, as well as a partial quarter of 430 Rozzi Place and Sugarland Business Park, Building Two. Included in the six months ended June 30, 2003 is The Arboretum, Decoverly Two, Three, and Seven and 38 Cabot Boulevard, 430 Rozzi Place and Sugarland Business Park, Building One and Two as well as a partial quarter of 875 Third Avenue and The Candler Building.

Gains on the sales of real estate for the six months ended June 30, 2004 in the Total Portfolio relate to the sale of Hilltop Office Center and a land parcel in Burlington, MA. Gains for the six months ended June 30, 2003 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 year ended June 30, 2004 in the Total Portfolio primarily related to the gain recognized on 430 Rozzi Place and Sugarland Business Park, Building Two, The Arboretum, Decoverly Two, Three and Seven and 38 Cabot Boulevard. Gains on sales of real estate from discontinued operations for the year ended June 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 June 30, 2004 to the three months ended June 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 115 properties totaling approximately 29.7 million square feet of office space and three hotel properties acquired or placed in-service on or prior to April 1, 2003 and owned through June 30, 2004. The Total Property Portfolio includes amounts from properties either placed in-service or acquired after April 1, 2003 or disposed of on or prior to June 30, 2004.

Rental Revenue

The increase in rental revenue of $22.5 million in the Total Portfolio primarily relates 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 $17.6 million, as detailed below:


		Revenue for the three months ended June 30,
Property	Date Acquired	2004		2003		Change
		(in thousands)
One and Two Freedom Square	August 5, 2003	$	7,380	$	—	$	7,380
1333 New Hampshire Avenue	October 8, 2003		3,867		—		3,867
140 Kendrick Street	March 24, 2004		2,719		—		2,719
1330 Connecticut Avenue	April 1, 2004		3,584		—		3,584

Total Additions		$	17,550	$	—	$	17,550

In addition, the placing into service of (1) Shaws Supermarket in Boston in 2003 and (2) a portion of Times Square Tower as of April 1, 2004 increased revenue $6.4 million for the quarter ended June 30, 2004 compared to June 30, 2003. Same Property Portfolio decreased slightly for the three months ended, reflecting increasing base rents of approximately $1.4 million offset by a decrease in straight-line rent of $2.3 million. We anticipate roll-downs in rent on our expiring leases over the foreseeable future. The impact of these roll-downs and the vacancy we assume on any lease roll-over will decrease our Same Property revenue.

Termination Income

There was no termination income for the three months ended June 30, 2004, compared to termination income earned for the three months ended June 30, 2003 related to five tenants totaling $1.4 million. We expect to recognize termination income in the third quarter of 2004 resulting from a transaction in New York City in which a tenant will pay approximately $1.0 million to cancel a lease.

Development and Management Services

Our third-party fee income increased $0.5 million for the second quarter of 2004 compared to the second quarter of 2003. We continue to pursue new fee-for-service projects and may be able to increase this fee business as we move into the later part of 2004 and 2005. Our existing third-party fees continue in Washington, D.C. with 901 New York Avenue and National Institute of Health, as well as in New York at 90 Church Street, which collectively contributed $2.7 million to development and management services for the three months ended June 30, 2004 and 2003.

Interest and Other Income

Interest and other income increased by $0.4 million in the Total Portfolio for the three months ended June 30, 2004. At the end of the second quarter we had a cash balance of approximately $228 million. To the extent we don’t acquire any properties or fund new developments, we anticipate interest will increase through the end of the year.

Operating Expenses

BOSTON PROPERTIES LIMITED PARTNERSHIP

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 (1) Shaws Supermarket in 2003 and (2) a portion of Times Square Tower as of April 1, 2004 increased operating expenses by $0.7 million. The remaining increase of $2.4 million is due to the overall increase in Same Property Portfolio operating expenses, the majority of which is due to an increase in real estate tax assessment for our properties in New York City.

Hotel Net Operating Income

Net operating income for the hotel properties increased by $0.8 million or approximately 16.85% for the three months ended June 30, 2004 compared to the three months ended June 30, 2003. On a year to year basis, our hotels had a strong second quarter.

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


	2004			2003			Increase (Decrease)
Occupancy		87.1	%		79.8	%	9.1	%
Average daily rate	$	180.22		$	173.82		3.7	%
Revenue per available room, REVPAR	$	157.06		$	138.95		13.0	%

Other Expenses

General and Administrative

General and administrative expenses in the Total Portfolio increased during the three months ended June 30, 2004 as compared to the three months ended June 30, 2003 by $1.5 million or 13.28%. 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. The remaining increase is due to compensation expense increases during 2004.

In 2003, Boston Properties, Inc. transitioned to using solely restricted stock and/or LTIP Units as opposed to granting stock options and restricted stock under the 1997 Stock Option and Incentive Plan as its 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 Boston Properties, Inc.’s 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 June 30, 2004. Stock-based compensation expense associated with $6.1 million of restricted stock that was granted by Boston Properties, Inc. 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 issued by Boston Properties, Inc. 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 the Board of Directors of Boston Properties Inc. continues its 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 higher costs 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 decreased as a result of our paying off some mortgage debt during 2004 with our equity offering proceeds during the first quarter of 2004. In March 2004, we repaid the mortgage loan secured by One and Two Reston Overlook, Lockheed Martin and NIMA properties, totaling approximately $110.3 million. Our total debt outstanding at June 30, 2004 was approximately $5.0 billion compared to $4.8 billion at June 30, 2003. Despite increases in short-term market interest rates from June 30, 2003 to 2004, our weighted average rate on variable rate debt has decreased primarily as a result of refinancing of Times Square Tower during January 2004. The following summarizes our debt outstanding for the three months ended June 30, 2004 compared with 2003.

Depreciation and Amortization

Depreciation and amortization expense for the Total Portfolio increased as a result of the addition of One and Two Freedom Square, 1333 New Hampshire Avenue, 140 Kendrick Street, and 1330 Connecticut Avenue which collectively represented an aggregate of $4.2 million of the increase. Increases in Same Property Portfolio represented $5.0 million.

Costs directly related to the development of rental properties are capitalized. 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 June 30, 2004 and 2003 were $1.6 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 June 30, 2004 and 2003 was $3.5 million and $4.6 million, respectively. These costs are not included in the interest expense referenced above. During the three months ended June 30, 2004 we placed a portion of Times Square Tower into service. As we continue to place this building into service, the capitalized costs will decrease and depreciation and amortization expense will increase.

Net Derivative Losses

BOSTON PROPERTIES LIMITED PARTNERSHIP

modification 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, One and Two Discovery Square and One and Two Freedom Square. 140 Kendrick Street is included in the Total Portfolio Revenue as of March 24, 2004. One and Two Discovery Square are included in the Total Portfolio Revenue as of April 1, 2003. One and Two Freedom Square are included in the Total Portfolio Revenue as of August 5, 2003. The reclassification of these properties caused the overall income from joint ventures to decrease $0.5 million for the three months ended June 30, 2004 compared to the three months ended June 30, 2003.

Other

The decrease in income from discontinued operations in the Total Portfolio for the three months ended June 30, 2004 was a result of properties sold during the second quarter 2004. We did not recognize a full quarter of revenue and expenses with respect to these properties. Included in the three months ended June 30, 2004 is a full quarter Sugarland Business Park, Building One and a partial quarter of 38 Cabot Boulevard. Included in the three months ended June 30, 2003 is a full quarter of The Arboretum, Decoverly Two, Three and Seven, 38 Cabot Boulevard, 430 Rozzi Place and Sugarland Business Park, Building One and Two.

Gains on the sales of real estate for the three months ended June 30, 2004 in the Total Portfolio relate to the sale of a land parcel in Burlington MA. In the second quarter of 2003 there was a transfer of mortgage benefit that resulted in a gain of $3.4 million.

Gains on sales of real estate from discontinued operations for the quarter ended June 30, 2004 in the Total Portfolio primarily related to the gain recognized on The Arboretum, Decoverly Two, Three, Six and Seven and 38 Cabot Boulevard. There were no gains on sales of real estate from discontinued operations for the quarter ended June 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 Boston Properties, Inc.’s 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 minimum distribution required to maintain Boston Properties, Inc.’s REIT qualification. We seek to increase

BOSTON PROPERTIES LIMITED PARTNERSHIP

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 equity securities of Boston Properties, Inc. and/or additional preferred or common units of partnership interest; 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 needs. We fund our development projects with construction loans that we may partially guarantee until the project completion or lease-up thresholds are achieved. In March 2004, Boston Properties, Inc. completed a public offering of 5,700,000 shares of its common stock. Boston Propertiesc, Inc. contributed the proceeds from this offering, net of underwriters’ discount and offering costs, of approximately $291.1 million to us in exchange for 5,700,000 common units. In addition, during 2003 Boston Properties Inc. completed three offerings of unsecured senior notes and expect to 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 $227.7 million and $158.6 million at June 30, 2004 and 2003, respectively, representing an increase of $69.1 million. The decrease was a result of the following increases and decreases in cash flows:


	Three months ended June 30,
	(in thousands)
	2004			2003			Increase (Decrease)
Net cash provided by operating activities	$	210,586		$	249,843		$	(39,257	)
Net cash provided by (used in) investing activities	$	(67,103	)	$	383,919		$	(451,022	)
Net cash provided by (used in) financing activities	$	61,529		$	(530,450	)	$	591,979

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

BOSTON PROPERTIES LIMITED PARTNERSHIP

borrowings as well as the March 2004 public offering of 5,700,000 shares of Boston Properties, Inc.’s 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 7.2 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 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 June 30, 2004 consisted of the following:


	(in thousands)
Proceeds from the sales of real estate	$	90,555
The cash provided by investing is partially offset by:
Investments in unconsolidated joint ventures		(714	)

Hotel improvements, equipment upgrades and replacements		(228	)
Acquisitions/additions to real estate		(151,597	)

Net cash used in investing activities	$	(67,103	)

Cash provided by financing activities for the three months ended June 30, 2004 totaled approximately $61.5 million. This consisted of payments of distributions to 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 Boston Properties, Inc.’s common stock offering in March 2004. Future debt payments are discussed below under the heading “Capitalization.”

Capitalization

At June 30, 2004, our total consolidated debt was approximately $5.0 billion. The weighted-average annual interest rate on our consolidated indebtedness was 6.28% and the weighted-average maturity was approximately 6.1 years.

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 $11.8 billion at June 30, 2004. Total market capitalization was calculated using the June 30, 2004 Boston Properties Inc.’s closing stock price of $50.08 per common share and the following: (1) 108,160,487 common units of BPLP held by Boston Properties, Inc., (2) 22,046,317 outstanding common units of BPLP (excluding common units held by Boston Properties, Inc.), (3) an aggregate of 5,682,714 common units issuable upon conversion of all outstanding preferred units of BPLP, (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 June 30, 2004 represented approximately 42.33% of our total market capitalization. This percentage will fluctuate with changes in the market price of Boston Properties, Inc.’s common stock and does not necessarily reflect our capacity to incur additional debt to finance our activities or our ability to manage our existing debt obligations. However, for a company like ours, whose assets are primarily income-producing real estate, the debt to total market

BOSTON PROPERTIES LIMITED PARTNERSHIP

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.

In April 2004, a non-U.S. institutional investor requested a waiver of the application of the 6.6% ownership limit provided in Boston Properties, Inc.’s charter to enable the investor to beneficially own up to 9.9% of Boston Properties, Inc.’s common stock outstanding from time to time. Based upon representations, warranties and undertakings provided by the investor to help ensure that ownership by such investor would not cause Boston Properties, Inc. to fail to qualify as a REIT, its Board of Directors granted such waiver in May 2004.

Debt Financing

As of June 30, 2004, we had approximately $5.0 billion of outstanding indebtedness, representing 42.33% 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 amount outstanding on our unsecured line of credit as of June 30, 2004. The table below summarizes our mortgage notes payable, our senior unsecured notes and our revolving line of credit at June 30, 2004 and 2003:

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

BOSTON PROPERTIES LIMITED PARTNERSHIP

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.

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 distributions; and

•

a minimum net worth requirement.

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

At June 30, 2004, we had letters of credit totaling $5.7 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 $599.3 million under our Unsecured Line of Credit. As of August 3, 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 our 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 our 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 our 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.

BOSTON PROPERTIES LIMITED PARTNERSHIP

In December 2002, we completed an unregistered offering of $750 million in aggregate principal amount of our 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 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 June 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.

Unsecured Bridge Loan

On September 25, 2002, we obtained unsecured bridge financing totaling $1.0 billion in connection with the acquisition of 399 Park Avenue. During 2002, we repaid approximately $894.3 million with proceeds from the offering of unsecured senior notes and proceeds from the sales of certain real estate properties. At December 31, 2002, the unsecured bridge loan had an outstanding balance of approximately $105.7 million. During January 2003, we repaid all amounts outstanding under our unsecured bridge loan with proceeds from the January 2003 offering of senior unsecured notes.

Off Balance Sheet Arrangements—Joint Venture Indebtedness

As of June 30, 2004, we had investments in five unconsolidated joint ventures, of which four have mortgage indebtedness, with equity ownership ranging from 25–51%. 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 June 30, 2004, our proportionate share of the debt related to these investments was equal to approximately $151.3 million. The table below summarizes the outstanding debt (based on our respective ownership interests) in these joint venture properties at June 30, 2004.

Our partner has agreed to reimburse us for any amounts we pay in satisfaction of its guarantee obligations.

BOSTON PROPERTIES LIMITED PARTNERSHIP

State and Local Tax Matters

Because we are organized as a limited partnership, 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 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

BOSTON PROPERTIES LIMITED PARTNERSHIP

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 minority interests in property partnerships and our Operating Partnership, 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 measure. The use of FFO, combined with the required primary GAAP presentations, has been fundamentally beneficial, 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 the comparative operating and financial performance of the Company 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 supplemental adjustments, including net derivative losses. 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. FFO should not be considered as an alternative to net income (determined in accordance with GAAP) as an indication of our performance. FFO does not represent cash generated from operating activities determined in accordance with GAAP and is not a measure of liquidity or an indicator of our ability to make cash distributions. We believe that to further understand our performance, FFO 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

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 ending 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 our Series Two Preferred Units constitutes a participating security. The adoption of EITF 03-6 has resulted in a reduction of net income available to common unit holders for those periods in which we 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 $4.5 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 June 30, 2004 ranged from LIBOR/Eurodollar plus 0.90% to LIBOR/Eurodollar plus 1.25%.

Assumes exercise by the Company 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 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.

BOSTON PROPERTIES LIMITED PARTNERSHIP

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 $4.8 million at June 30, 2004.

At June 30, 2004, our variable rate debt outstanding was approximately $445 million. At June 30, 2004, the average interest rate on variable rate debt was approximately 2.28%. If market interest rates on our variable rate debt had been 100 basis points greater, total interest expense would have increased approximately $0.1 million for the three months ended June 30, 2004.

At June 30, 2003, our variable rate debt outstanding was approximately $308 million. At June 30, 2003, the average interest rate on variable rate debt was approximately 2.95%. If market interest rates on our variable rate debt had been 100 basis points greater, total interest expense would have increased approximately $0.1 million for the three months ended June 30, 2003.

FORM OF INDEMNIFICATION AGREEMENT

Exhibit 10.1

INDEMNIFICATION AGREEMENT

This Agreement made and entered into this day of May, 2004 (the “Agreement”), by and among Boston Properties, Inc., a Delaware corporation (“BXP,” which term shall include any Entity (as hereinafter defined) controlled directly or indirectly by BXP), Boston Properties Limited Partnership, a Delaware limited partnership (the “Operating Partnership”), and (the “Indemnitee”). The term “Company” as used in this Agreement is intended to refer to both or either of BXP and/or the Operating Partnership, as the context requires so as to interpret the relevant provision in such a manner as to permit the broadest scope of allowable indemnification for Indeminitee hereunder permitted by applicable law and regulations.

WHEREAS, BXP desires to attract and retain the services of highly qualified individuals, such as Indemnitee, to serve as directors and/or officers of BXP;

WHEREAS, increased corporate litigation has subjected directors and officers to litigation risks and expenses, and there are limitations on the availability of directors and officers liability insurance;

WHEREAS, BXP’s By-laws, as amended (the “By-laws”), require it to indemnify its directors and officers to the fullest extent permitted by law and permit it to make other indemnification arrangements and agreements;

WHEREAS, the Company desires to provide Indemnitee with specific contractual assurance of Indemnitee’s rights to full indemnification against litigation risks and expenses (regardless, among other things, of any amendment to or revocation of BXP’s Amended and Restated Certificate of Incorporation, as amended (the “Charter”) or By-laws or any change in the ownership of the Company or the composition of its Board of Directors);

WHEREAS, the Company intends that this Agreement provide Indemnitee with greater protection than that which is provided by BXP’s By-laws, and if Indemnitee is a party to a prior Indemnification Agreement with the Company, that this Agreement shall supercede such Indemnification Agreement as to provide uniformity among all similarly situated persons; and

WHEREAS, Indemnitee is relying upon the rights afforded under this Agreement in continuing as a director and/or officer of the Company.

NOW, THEREFORE, in consideration of the promises and the covenants contained herein, the Company and Indemnitee do hereby covenant and agree as follows:

1. Definitions.

(a) “Corporate Status” describes the status of a person who is serving or has served (i) as a director and/or officer of the Company, (ii) in any capacity with

respect to any employee benefit plan of the Company, or (iii) as a director, partner, trustee, officer, employee, agent, member or manager of any other Entity at the request of the Company. For purposes of subsection (iii) of this Section 1(a), if Indemnitee is serving or has served as a director, partner, trustee, officer, employee or agent of a Subsidiary, Indemnitee shall be deemed to be serving at the request of the Company.

(b) “Entity” shall mean any corporation, partnership, limited liability company, joint venture, trust, foundation, association, organization or other legal entity.

(c) “Expenses” shall mean all fees, costs and expenses incurred by Indemnitee in connection with any Proceeding (as defined below), including, without limitation, attorneys’ fees, disbursements and retainers (including, without limitation, any such fees, disbursements and retainers incurred by Indemnitee pursuant to Sections 10 and 11(c) of this Agreement), fees and disbursements of expert witnesses, private investigators and professional advisors (including, without limitation, accountants and investment bankers), court costs, transcript costs, fees of experts, travel expenses, duplicating, printing and binding costs, telephone and fax transmission charges, postage, delivery services, secretarial services, and other disbursements and expenses.

(d) “Indemnifiable Expenses,” “Indemnifiable Liabilities” and “Indemnifiable Amounts” shall have the meanings ascribed to those terms in Section 3(a) below.

(e) “Liabilities” shall mean judgments, damages, liabilities, losses, penalties, excise taxes, fines and amounts paid in settlement.

(f) “Proceeding” shall mean any threatened, pending or completed claim, action, suit, arbitration, alternate dispute resolution process, inquiry, subpoena, investigation, administrative hearing, appeal, or any other proceeding, whether civil, criminal, administrative, arbitrative or investigative, in each case whether formal or informal, including a proceeding initiated by Indemnitee pursuant to Section 10 of this Agreement to enforce Indemnitee’s rights hereunder.

(g) “Subsidiary” shall mean any corporation, partnership, limited liability company, joint venture, trust or other Entity of which the Company owns (either directly or through or together with another Subsidiary of the Company) either (i) a general partner, managing member or other similar interest or (ii) (A) 50% or more of the voting power of the voting capital equity interests of such corporation, partnership, limited liability company, joint venture, trust or other Entity, or (B) 50% or more of the outstanding voting capital stock or other voting equity interests of such corporation, partnership, limited liability company, joint venture, trust or other Entity.

2. Services of Indemnitee. In consideration of the Company’s covenants and commitments hereunder, Indemnitee agrees to serve or continue to serve as a director and/or officer of the Company. However, this Agreement shall not impose any obligation on Indemnitee or the Company to continue Indemnitee’s service to the Company beyond any period otherwise required by law or by other agreements or commitments of the parties, if any.

3. Agreement to Indemnify. The Company agrees to indemnify Indemnitee as follows:

(a) Proceedings Other Than By or In the Right of the Company. Subject to the exceptions contained in Section 4(a) below, if Indemnitee was or is a party or is threatened to be made a party to any Proceeding or was or is a witness or is threatened to be made a witness in any Proceeding (other than an action by or in the right of the Company), in each case by reason of Indemnitee’s Corporate Status, Indemnitee shall be indemnified by the Company against all Expenses and Liabilities incurred or paid by Indemnitee in connection with such Proceeding (referred to herein as “Indemnifiable Expenses” and “Indemnifiable Liabilities,” respectively, and collectively as “Indemnifiable Amounts”). The Company hereby agrees to indemnify Indemnitee’s spouse (whether by statute or at common law and without regard to the location of the governing jurisdiction) and children (including by way of adoption) as express third-party beneficiaries hereunder to the same extent and subject to the same limitations applicable to Indemnitee hereunder for claims arising out the status of such person as a spouse or child of Indemnitee, including claims seeking damages from marital property (including community property) and property held by the Indemnitee and such spouse or property transferred to such spouse or child.

(b) Proceedings By or In the Right of the Company. Subject to the exceptions contained in Section 4(b) below, if Indemnitee was or is a party or is threatened to be made a party to any Proceeding by or in the right of the Company by reason of Indemnitee’s Corporate Status, Indemnitee shall be indemnified by the Company against all Indemnifiable Expenses and, to the fullest extent permitted by law, amounts paid in settlement.

(c) Conclusive Presumption Regarding Standard of Care. In making any determination required to be made under Delaware law with respect to entitlement to indemnification hereunder, the person, persons or entity making such determination shall presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee submitted a request therefor in accordance with Section 5 of this Agreement, and the Company shall have the burden of proof to

overcome that presumption in connection with the making by any person, persons, entity, regulatory authority or court of any determination contrary to that presumption.

4. Exceptions to Indemnification. Indemnitee shall be entitled to indemnification under Sections 3(a) and 3(b) above in all circumstances other than with respect to any specific claim, issue or matter involved in the Proceeding out of which Indemnitee’s claim for indemnification has arisen to which any of Sections 4(a), 4(b) or 4(c) below applies:

(a) Proceedings Other Than By or In the Right of the Company. If indemnification is requested under Section 3(a) and it has been finally adjudicated by a court of competent jurisdiction that, in connection with such specific claim, issue or matter, Indemnitee failed to act (i) in good faith and (ii) in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, or, with respect to any criminal Proceeding, Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful, Indemnitee shall not be entitled to payment of Indemnifiable Amounts hereunder with respect to such claim, issue or matter.

(b) Proceedings By or In the Right of the Company. If indemnification is requested under Section 3(b) and:

(i) it has been finally adjudicated by a court of competent jurisdiction that, in connection with such specific claim, issue or matter, Indemnitee failed to act (A) in good faith and (B) in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, Indemnitee shall not be entitled to payment of Indemnifiable Expenses, or amounts paid in settlement, hereunder with respect to such claim, issue or matter; or

(ii) it has been finally adjudicated by a court of competent jurisdiction that Indemnitee is liable to the Company with respect to such specific claim, issue or matter, Indemnitee shall not be entitled to payment of Indemnifiable Expenses, or amounts paid in settlement, hereunder with respect to such claim, issue or matter unless the Court of Chancery or another court in which such Proceeding was brought shall determine upon application that, despite the adjudication of liability, but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnification for such Indemnifiable Expenses or amounts paid in settlement as such court shall deem proper; or

(iii) it has been finally adjudicated by a court of competent jurisdiction that Indemnitee is liable to the Company for an accounting of profits made from the purchase or sale by the Indemnitee of securities of the Company pursuant to the provisions of Section 16(b) of the Securities Exchange Act of 1934, the rules and regulations promulgated thereunder and amendments thereto or similar provisions of any federal, state or local statutory law, Indemnitee shall not be entitled to payment of Indemnifiable Expenses or amounts paid in settlement, hereunder with respect to such issue, claim or matter.

(c) Insurance Proceeds. To the extent payment is actually made to the Indemnitee under a valid and collectible insurance policy in respect of Indemnifiable Amounts in connection with such specific claim, issue or matter, Indemnitee shall not be entitled to payment of Indemnifiable Amounts hereunder except in respect of any excess beyond the amount of payment under such insurance.

5. Procedure for Payment of Indemnifiable Amounts. Indemnitee shall submit to the Company a written request specifying the Indemnifiable Amounts for which Indemnitee seeks payment under Section 3 of this Agreement and the basis for the claim. The Company shall pay such Indemnifiable Amounts to Indemnitee within forty-five (45) calendar days of receipt of the request. At the request of the Company, Indemnitee shall furnish such documentation and information as are reasonably available to Indemnitee and necessary to establish that Indemnitee is entitled to indemnification hereunder.

6. Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other provision of this Agreement, and without limiting any such provision, to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a party to and is successful, on the merits or otherwise, in any Proceeding, Indemnitee shall be indemnified against all Expenses reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with each successfully resolved claim, issue or matter. For purposes of this Agreement, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, by reason of settlement, judgment, order or otherwise, shall be deemed to be a successful result as to such claim, issue or matter.

7. Effect of Certain Resolutions. Neither the settlement or termination of any Proceeding nor the failure of the Company to award indemnification or to determine that indemnification is payable shall create a presumption that Indemnitee is not entitled to indemnification hereunder. In addition, the termination of any proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent shall not create a presumption that Indemnitee did not act in good faith and in a manner which Indemnitee

reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, had reasonable cause to believe that Indemnitee’s action was unlawful.

8. Agreement to Advance Expenses; Undertaking. The Company shall advance all Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding, including a Proceeding by or in the right of the Company, in which Indemnitee is involved by reason of such Indemnitee’s Corporate Status within ten (10) calendar days after the receipt by the Company of a written statement from Indemnitee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. To the extent required by Delaware law, Indemnitee hereby undertakes to repay any and all of the amount of Indemnifiable Expenses paid to Indemnitee if it is finally determined by a court of competent jurisdiction in accordance with Section 4 above that Indemnitee is not entitled under this Agreement to indemnification with respect to such Expenses. This undertaking is an unlimited general obligation of Indemnitee.

9. Procedure for Advance Payment of Expenses. Indemnitee shall submit to the Company a written request or requests specifying the Indemnifiable Expenses for which Indemnitee seeks an advancement under Section 8 of this Agreement, together with documentation evidencing that Indemnitee has incurred such Indemnifiable Expenses. Payment of Indemnifiable Expenses under Section 8 shall be made no later than ten (10) calendar days after the Company’s receipt of each such request.

10. Remedies of Indemnitee.

(a) Right to Petition Court. In the event that Indemnitee makes a request for payment of Indemnifiable Amounts under Sections 3 and 5 above or a request for an advancement of Indemnifiable Expenses under Sections 8 and 9 above and the Company fails to make such payment or advancement in a timely manner pursuant to the terms of this Agreement, Indemnitee may petition the Court of Chancery to enforce the Company’s obligations under this Agreement.

(b) Burden of Proof. In any judicial proceeding brought under Section 10(a) above, the Company shall have the burden of proving that Indemnitee is not entitled to payment of Indemnifiable Amounts hereunder.

(c) Expenses. The Company agrees to reimburse Indemnitee in full for any Expenses incurred by Indemnitee in connection with investigating, preparing for, litigating, defending or settling any action brought by Indemnitee under Section 10(a) above, or in connection with any claim or counterclaim brought by the Company in connection therewith, whether or not Indemnitee is successful in whole or in part in connection with any such action.

(d) Failure to Act Not a Defense. The failure of the Company (including its Board of Directors or any committee thereof, independent legal counsel, or stockholders) to make a determination concerning the permissibility of the payment of Indemnifiable Amounts or the advancement of Indemnifiable Expenses under this Agreement shall not be a defense in any action brought under Section 10(a) above, and shall not create a presumption that such payment or advancement is not permissible.

11. Defense of the Underlying Proceeding.

(a) Notice/Cooperation by Indemnitee. Indemnitee agrees to notify the Company promptly upon being served with any summons, citation, subpoena, request for information or documents, complaint, indictment, information, or other document relating to any Proceeding which may result in the payment of Indemnifiable Amounts or the advancement of Indemnifiable Expenses hereunder; provided, however, that the failure to give any such notice shall not disqualify Indemnitee from the right, or otherwise affect in any manner any right of Indemnitee, to receive payments of Indemnifiable Amounts or advancements of Indemnifiable Expenses unless the Company’s ability to defend in such Proceeding is materially and adversely prejudiced thereby. Indemnitee shall give the Company such information and cooperation as it may reasonably require and as shall be within Indemnitee’s power.

(b) Defense by Company. Subject to the provisions of the last sentence of this Section 11(b) and of Section 11(c) below, the Company shall have the right to defend Indemnitee in any Proceeding which may give rise to the payment of Indemnifiable Amounts hereunder with counsel approved by Indemnitee, which approval shall not be unreasonably withheld, provided, however that the Company shall notify Indemnitee of any such decision to defend within ten (10) calendar days of receipt of notice of any such Proceeding under Section 11(a) above. The Company shall not, without the prior written consent of Indemnitee, consent to the entry of any judgment against Indemnitee or enter into any settlement or compromise which (i) includes an admission or finding of fault of Indemnitee or (ii) does not include, as an unconditional term thereof, the full release of Indemnitee from all liability in respect of such Proceeding, which release shall be in form and substance reasonably satisfactory to Indemnitee. This Section 11(b) shall not apply to a Proceeding brought by Indemnitee under Section 10(a) above or pursuant to Section 19 below.

(c) Indemnitee’s Right to Counsel. Notwithstanding the provisions of Section 11(b) above, if in a Proceeding to which Indemnitee is a party by reason of Indemnitee’s Corporate Status, (i) Indemnitee reasonably concludes that he or she may have separate defenses or counterclaims to assert with respect to any issue which may not be consistent with the position of other defendants in such Proceeding, (ii) a conflict of interest or potential conflict of interest exists between Indemnitee and the Company, or between Indemnitee and another

director or officer of the Company who is defended by the Company with the same counsel as counsel representing Indemnitee or (iii) if the Company fails to assume the defense of such proceeding in a timely manner, Indemnitee shall be entitled to be represented by separate legal counsel of Indemnitee’s choice at the expense of the Company. In addition, if the Company fails to comply with any of its obligations under this Agreement or in the event that the Company or any other person takes any action to declare this Agreement void or unenforceable, or institutes any action, suit or proceeding to deny or to recover from Indemnitee the benefits intended to be provided to Indemnitee hereunder, Indemnitee shall have the right to retain counsel of Indemnitee’s choice, at the expense of the Company, to represent Indemnitee in connection with any such matter.

12. Representations and Warranties of the Company. The Company hereby represents and warrants to Indemnitee as follows:

(a) Authority. The Company has all necessary power and authority to enter into, and be bound by the terms of, this Agreement, and the execution, delivery and performance of the undertakings contemplated by this Agreement have been duly authorized by the Company.

(b) Enforceability. This Agreement, when executed and delivered by the Company in accordance with the provisions hereof, shall be a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, moratorium, reorganization or similar laws affecting the enforcement of creditors’ rights generally.

13. Insurance. The Company shall, from time to time, make the good faith determination whether or not it is practicable for the Company to obtain and maintain a policy or policies of insurance with a reputable insurance company providing the Indemnitee with coverage for losses from wrongful acts. For so long as Indemnitee shall remain a director or officer of the Company and with respect to any such prior service, in all policies of director and officer liability insurance, Indemnitee shall be named as an insured in such a manner as to provide Indemnitee the same rights and benefits as are accorded to the most favorably insured of the Company’s officers and directors. Notwithstanding the foregoing, the Company shall have no obligation to obtain or maintain such insurance if the Company determines in good faith that such insurance is not reasonably available, if the premium costs for such insurance are disproportionate to the amount of coverage provided, or if the coverage provided by such insurance is limited by exclusions so as to provide an insufficient benefit. The Company shall promptly notify Indemnitee of any good faith determination not to provide such coverage.

14. Contract Rights Not Exclusive. The rights to payment of Indemnifiable Amounts and advancement of Indemnifiable Expenses provided by this Agreement shall be in addition to, but not exclusive of, any other rights which Indemnitee may have at any time under applicable law, the Charter or By-laws, or any other agreement, vote of stockholders or directors (or a committee of directors), or otherwise, both as to action in Indemnitee’s official capacity and as to action in any other capacity as a result of Indemnitee’s serving as a director or officer of the Company.

15. Successors. This Agreement shall be (a) binding upon all successors and assigns of the Company (including any transferee of all or a substantial portion of the business, stock and/or assets of the Company and any direct or indirect successor by merger or consolidation or otherwise by operation of law) and (b) binding on and shall inure to the benefit of the heirs, personal representatives, executors and administrators of Indemnitee. This Agreement shall continue for the benefit of Indemnitee and such heirs, personal representatives, executors and administrators after Indemnitee has ceased to have Corporate Status.

16. Subrogation. In the event of any payment of Indemnifiable Amounts under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of contribution or recovery of Indemnitee against other persons, and Indemnitee shall take, at the request of the Company, all reasonable action necessary to secure such rights, including the execution of such documents as are necessary to enable the Company to bring suit to enforce such rights.

17. Change in Law. To the extent that a change in Delaware law or other applicable law or regulation (whether by statute or judicial decision) shall permit broader indemnification or advancement of expenses than is provided under the terms of the By-laws and this Agreement, Indemnitee shall be entitled to such broader indemnification and advancements, and this Agreement shall be deemed to be amended to such extent.

18. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such a manner as to be effective and valid under applicable law, but if any provision of this Agreement, or any clause thereof, shall be determined by a court of competent jurisdiction to be illegal, invalid or unenforceable, in whole or in part, such provision or clause shall be limited or modified in its application to the minimum extent necessary to make such provision or clause valid, legal and enforceable, and the remaining provisions and clauses of this Agreement shall remain fully enforceable and binding on the parties.

19. Indemnitee as Plaintiff. Except as provided in Section 10 of this Agreement and in the next sentence of this Section 19, Indemnitee shall not be entitled to payment of Indemnifiable Amounts or advancement of Indemnifiable Expenses with respect to any Proceeding brought by Indemnitee against the Company, any Entity which it controls, any director or officer thereof, or any third party, unless the Board of Directors of the Company has consented to the initiation of such Proceeding. This Section shall not apply to counterclaims or affirmative defenses asserted by Indemnitee in an action brought against Indemnitee.

20. Modifications and Waiver. Except as provided in Section 17 above with respect to changes in Delaware law which broaden the right of Indemnitee to be indemnified by the Company, no supplement, modification or amendment of this Agreement shall be binding unless executed in writing by each of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions of this Agreement (whether or not similar), nor shall such waiver constitute a continuing waiver.

21. General Notices. All notices, requests, demands and other communications hereunder shall be in writing and shall be deemed to have been duly given (a) when delivered by hand, (b) when transmitted by facsimile and receipt is acknowledged, or (c) if mailed by certified or registered mail with postage prepaid, on the third business day after the date on which it is so mailed:

		Boston, MA 02199-7610
		Attn: General Counsel

or to such other address as may have been furnished in the same manner by any party to the others.

22. Governing Law; Consent to Jurisdiction; Service of Process. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without regard to its rules of conflict of laws. Each of the Company and the Indemnitee hereby irrevocably and unconditionally consents to submit to the exclusive jurisdiction of the Court of Chancery of the State of Delaware and the courts of the United States of America located in the State of Delaware (the “Delaware Courts”) for any litigation arising out of or relating to this Agreement and the transactions contemplated hereby (and agrees not to commence any litigation relating thereto except in such courts), waives any objection to the laying of venue of any such litigation in the Delaware Courts and agrees not to plead or claim in any Delaware Court that such litigation brought therein has been brought in an inconvenient forum. Each of the parties hereto agrees, (a) to the extent such party is not otherwise subject to service of process in the State of Delaware, to appoint and maintain an agent in the State of Delaware as such party’s agent for acceptance of legal process, and (b) that service of process may also be made on such party by prepaid certified mail with a proof of mailing receipt validated by the United States Postal Service constituting evidence of valid service. Service made pursuant to (a) or (b) above shall have the same legal force and effect as if served upon such party personally within the State of Delaware. For purposes of implementing the parties’ agreement to appoint and maintain an agent for service of process in the State of Delaware, each such party does hereby appoint The Corporation Trust Company, 1209 Orange Street, Wilmington, New Castle County, Delaware 19801, as such agent and each such party hereby agrees to complete all actions necessary for such appointment.

23. Joint and Several Liability. BXP and the Operating Partnership each agree to be held jointly and severally liable for their obligations under this Agreement.

24. Prior Agreement. Indemnitee and the Company agree that the Indemnification Agreement by and among BXP, the Operating Partnership, Boston Properties Management, Inc., a Delaware corporation and the Indemnitee dated as of June 23, 1997 is terminated upon the execution of this Agreement.

The ratio of earnings to combined fixed charges and preferred distributions was computed by dividing earnings by combined fixed charges and preferred distributions. Earnings consist of income before minority interests in property partnerships, income from unconsolidated joint ventures, discontinued operations, cumulative effect of a change in accounting principle and preferred distributions, plus amortization of interest capitalized, distributions from unconsolidated joint ventures, and combined fixed charges and preferred distributions, minus interest capitalized and preferred distributions. Combined fixed charges and preferred distributions consist of interest expensed, which includes credit enhancement fees and amortization of loan costs, interest capitalized, and preferred distributions.
