        As used in this registration statement on Form 10, which we sometimes refer to as this Form 10, unless the context otherwise requires, the terms "BPLP," "we," "us," and "our" refer collectively to Boston Properties Limited Partnership, a Delaware limited partnership, and its subsidiaries, and its respective predecessor entities, considered as a single enterprise.


Item 1.    Business

General

        Boston Properties Limited Partnership is the entity through which Boston Properties, Inc., a fully integrated self-administered and self-managed real estate investment trust or "REIT" and one of the largest owners and developers of office properties in the United States, conducts substantially all of its business and owns (either directly or through subsidiaries) substantially all of its assets. Boston Properties, Inc.'s common stock, par value $.01 per share, is listed on the New York Stock Exchange under the symbol "BXP."

        Our properties are concentrated in four core markets: Boston, Washington, D.C., midtown Manhattan and San Francisco. At December 31, 2002, we owned or had interests in 142 properties, totaling 42.4 million net rentable square feet. Our properties consisted of 133 office properties, comprised of 105 Class A office buildings and 28 properties that support both office and technical uses, including five properties under construction, four industrial properties, two retail properties, including one retail property under construction, and three hotels. Subsequent to December 31, 2002, we sold two Class A office properties. We consider Class A office buildings to be centrally located buildings that are professionally managed and maintained, attract high-quality tenants and command upper-tier rental rates, and that are modern structures or have been modernized to compete with newer buildings. Our definition of Class A office buildings may be different than that of other companies.

        We are a full service real estate company, with substantial in-house expertise and resources in acquisitions, development, financing, capital markets, construction management, property management, marketing, leasing, accounting, tax and legal services. We are managed by Boston Properties, Inc. in its capacity as our sole general partner. Consequently, we do not have employees of our own. As of December 31, 2002, Boston Properties, Inc. had approximately 675 employees. Its 31 senior officers have an average of 24 years experience in the real estate industry and an average of 15 years tenure with Boston Properties, Inc. Our principal executive office is located at 111 Huntington Avenue, Boston, Massachusetts 02199 and our telephone number at that address is (617) 236-3300. In addition, we have regional offices at 401 9th Street, NW, Washington, D.C. 20004; 599 Lexington Avenue, New York, New York 10022; Four Embarcadero Center, San Francisco, California 94111; and 302 Carnegie Center, Princeton, New Jersey 08540.

        Boston Properties, Inc., our sole general partner, has a Web site located at http://www.bostonproperties.com. On its Web site, you can obtain a copy of our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act of 1934, as amended, as soon as reasonably practicable after we file such material electronically with, or furnish it to, the Securities and Exchange Commission (the "SEC").

        At February 19, 2003, Boston Properties, Inc. was the owner of an approximately 76.3% economic interests in BPLP. Economic interest was calculated as the number of common partnership units of BPLP owned by Boston Properties, Inc. as a percentage of the sum of (i) the actual aggregate number of outstanding common partnership units of BPLP and (ii) the number of common partnership units issuable upon conversion of outstanding preferred partnership units of BPLP. This structure is commonly referred to as an umbrella partnership REIT or "UPREIT." Boston Properties, Inc.'s general and limited partnership interests in BPLP entitles it to share in cash distributions from, and in the profits and losses of, BPLP in proportion to its percentage interest therein and entitles it to vote on all

1


matters requiring a vote of the limited partners. The other limited partners are persons who contributed their direct or indirect interests in certain properties to us in exchange for common units of limited partnership interest in BPLP or preferred units of limited partnership interest in BPLP either in connection with Boston Properties, Inc.'s initial public offering in 1997 or in subsequent transactions. Pursuant to our limited partnership agreement, unitholders may tender their common units of BPLP for cash equal to the value of an equivalent number of shares of common stock of Boston Properties, Inc. In lieu of delivering cash, however, Boston Properties, Inc., as general partner, may, at its option, choose to acquire any units so tendered by issuing shares of its common stock in exchange for the common units. If Boston Properties, Inc. so chooses, its common stock will be exchanged for common units on a one-for-one basis. This one-for-one exchange ratio is subject to specified adjustments to prevent dilution. We currently anticipate that Boston Properties, Inc., as our general partner, will elect to issue common stock in connection with each such presentation for redemption rather than having us pay cash. With each such exchange or redemption, Boston Properties, Inc.'s percentage ownership in BPLP will increase. In addition, whenever Boston Properties, Inc. issues shares of its common stock other than to acquire common units of BPLP, it must contribute any net proceeds it receives to us and we must issue to it an equivalent number of our common units.

        Our preferred units have the rights, preferences and other privileges (including the right to convert into common units) as are set forth in amendments to our limited partnership agreement. As of February 19, 2003, we had two series of preferred units outstanding. The Series One preferred units have an aggregate liquidation preference of approximately $80.9 million and are entitled to a preferred distribution at a rate of 7.25% per annum, payable quarterly. Series One units are convertible into common units at the rate of $38.25 per common unit at the holder's election at any time. We have the right to convert into common units all or part of the Series One units on or after June 30, 2003, if the common stock of Boston Properties, Inc. at the time of our election is trading at a price of at least $42.08 per share.

        Our Series Two preferred units have an aggregate liquidation preference of approximately $270.0 million. The Series Two units are convertible, at the holder's election, into common units at a conversion price of $38.10 per common unit. Distributions on the Series Two units are payable quarterly and generally accrue at rates of 6.5% through December 31, 2002; 7.0% until May 12, 2009; and 6.0% thereafter. If distributions on the number of common units into which the Series Two units are convertible are greater than distributions calculated using the rates described in the preceding sentence for the applicable quarterly period, then the greater distributions are payable instead. The terms of the Series Two units provide that they may be redeemed for cash in six annual tranches, beginning on May 12, 2009, at the election of Boston Properties, Inc., as our general partner, or at the election of the holders. Boston Properties, Inc., as general partner, also has the right to convert into common units any Series Two units that are not redeemed when they are eligible for redemption.

Significant Transactions During 2002

Real Estate Acquisitions/Dispositions

        On September 25, 2002, we acquired 399 Park Avenue, an approximately 1.7 million square foot office tower in midtown Manhattan. The total acquisition cost of approximately $1.06 billion (including closing costs) was financed with an unsecured bridge loan totaling $1.0 billion and cash. The acquisition of 399 Park Avenue was structured so as to permit us to engage in like-kind exchanges in reliance on Section 1031 of the Internal Revenue Code, which structure allows us to dispose of properties with an aggregate value of up to $1.06 billion within a six-month period following the acquisition of 399 Park Avenue without recognizing gain for federal income tax purposes.

        During the year ended December 31, 2002, we sold land parcels in Herndon, Virginia and South San Francisco, California, and certain garage parking spaces at the Prudential Center in Boston,

2


Massachusetts, for gross proceeds of approximately $15.5 million, resulting in a gain on sale of approximately $4.6 million. In addition, on August 16, 2002, we acquired 20F Street, a 1/2 acre parcel of land in Washington, D.C., for approximately $2.4 million.

        On December 2, 2002, we sold 2391 West Winton Avenue in Hayward, California, an industrial property totaling approximately 220,000 net rentable square feet, for gross proceeds of approximately $10.8 million, resulting in a gain on sale of approximately $9.3 million.

        On November 22, 2002, we sold One and Two Independence Square in Washington, D.C., consisting of two Class A office properties totaling approximately 900,000 net rentable square feet, for gross proceeds of approximately $345.0 million which was used to repay secured and unsecured debt. We recognized a gain of approximately $227.8 million on the sale of One and Two Independence Square. As we continue to manage the property following the sale, the transaction has not been reflected as "discontinued operations" in our consolidated statements of operations.

        On November 25, 2002, we entered into a binding contract for the sale of 875 Third Avenue in midtown Manhattan, a Class A office building totaling approximately 719,000 net rentable square feet and subsequently closed the transaction on February 4, 2003, for approximately $361.3 million (excludes $8.8 million in future obligations assumed by the buyer relating to unpaid brokerage commissions and tenant improvement allowances). Proceeds of the sale were used to repay secured and unsecured debt. As we continued to manage the property following the sale, the transaction has not been reflected as "discontinued operations" in our consolidated statements of operations.

        On March 4, 2002, we sold Fullerton Square, consisting of two office/technical properties totaling 179,000 net rentable square feet in Springfield, Virginia, for gross proceeds of approximately $22.5 million, resulting in a gain on sale of approximately $7.1 million.

        On March 4, 2002, we sold 7600, 7700 and 7702 Boston Boulevard, consisting of three office/technical properties totaling approximately 195,000 net rentable square feet in Springfield, Virginia, for gross proceeds of approximately $34.1 million. Due to our obligation to provide development services related to the Boston Boulevard properties, that transaction did not qualify as a sale for financial reporting purposes in the first quarter of 2002 and had been accounted for as a financing transaction. During the third quarter of 2002, we completed our continuing involvement with the Boston Boulevard properties and recognized a gain on the sale of approximately $14.4 million.

        The sales mentioned above of One and Two Independence Square, 875 Third Avenue, 2391 West Winton and 7600, 7700 and 7702 Boston Boulevard were structured as like-kind exchanges. Accordingly, taxable gain for federal income tax purposes was recognized and the tax attributes (including depreciated tax basis and any tax protection covenants for the benefit of former owners) of these disposed properties have been transferred to 399 Park Avenue as the property for which they were exchanged.

Developments

        We placed five Class A office buildings and two office/technical properties in-service during 2002, which required a total investment during 2002 of approximately $148.9 million, of which $117.8 was funded through existing construction loans. Our total investment through December 31, 2002 on these properties was $924.0 million, including $806.6 million relating to 111 Huntington Avenue and 5 Times Square. We began or continued construction on an additional six office buildings, including two buildings in which we have a joint venture interest, and incurred approximately $172.4 million of construction costs during 2002, of which $111.0 million was funded through existing construction loans.

Unsecured Debt

        On December 13, 2002, we closed an unregistered offering of $750.0 million in aggregate principal amount of our 6.25% senior unsecured notes due 2013. The notes were offered only to qualified institutional buyers in reliance on Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"), and to certain investors outside of the United States in reliance on Regulation S under the Securities Act. The notes were priced at 99.65% of their face amount to yield 6.296%. We used the net proceeds to pay down our unsecured bridge loan which we incurred in connection with the acquisition of 399 Park Avenue in September 2002.

        On January 17, 2003, we closed an unregistered offering of an additional $175 million in aggregate principal amount of our 6.25% senior unsecured notes due 2013. The notes are fungible, and form a single series, with the notes sold in December 2002. The notes were offered only to qualified institutional buyers in reliance on Rule 144A under the Securities Act. The notes were priced at 99.763% of their face amount to yield 6.28%. We used the net proceeds to pay down our unsecured bridge loan, a portion of our unsecured line of credit as well as certain construction loans.

        In connection with the December 2002 and January 2003 offerings of our unsecured senior notes, we agreed to register an exchange offer in which the outstanding unregistered notes will be exchanged for registered notes of identical principal amount and with substantially identical terms.

        We received investment grade ratings on our inaugural offering of senior unsecured notes of:

Rating Organization
   Rating
Moody's   Baa2 (stable)
Standard & Poor's   BBB (stable)
FitchRatings   BBB (stable)

        A security rating is not a recommendation to buy, sell or hold securities, as it may be subject to revision or withdrawal at any time by the rating organization. Ratings assigned by each rating organization have their own meaning within the organization's overall classification system. Each rating should be evaluated independently of any other rating.

        In addition, 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. During January 2003, we repaid all remaining amounts outstanding under our unsecured bridge loan from the proceeds of the January 17, 2003 additional offering of unsecured senior notes mentioned above.

Equity Transactions

        On July 9, 2002, we converted certain of our Series Two and all of our Series Three preferred units of limited partnership interest, as well as all of the Series A Parallel preferred units of limited partnership interest underlying the shares of Boston Properties, Inc.'s Series A Convertible preferred stock, into common units of limited partnership interests. The preferred securities so converted had an aggregate liquidation preference of approximately $140.6 million.

Business and Growth Strategies

Business Strategy

        Our primary business objective is to maximize the economic return from our properties. Our strategy to achieve this objective is:

Growth Strategies

        We believe that we are well positioned to realize significant growth through external asset development and acquisitions. We believe that our development experience and our organizational depth position us to continue to develop a range of property types, from single-story suburban office properties to high-rise urban developments, within budget and on schedule. Other factors that contribute to our competitive position include:

5

        We have targeted three areas of development and acquisition as significant opportunities to execute our external growth strategy:

6

        We believe that significant opportunities will exist in the long term to increase cash flow from our existing properties because they are of high quality and in desirable locations. In addition, our properties are in markets where, in general, the creation of new supply is limited by the lack of available sites, the difficulty of receiving the necessary approvals for development on vacant land and obtaining financing. Our strategy for maximizing the benefits from these opportunities is two-fold: (1) to provide high quality property management services using our own employees in order to encourage tenants to renew, expand and relocate in our properties, and (2) to achieve speed and transaction cost efficiency in replacing departing tenants through the use of in-house services for marketing, lease negotiation, and construction of tenant improvements. In addition, we believe that once market conditions return, our hotel properties will add to our internal growth because of their desirable locations in the downtown Boston and East Cambridge submarkets. We expect to continue our internal growth as a result of our ability to:

Policies with Respect to Certain Activities

        The discussion below sets forth certain additional information regarding our investment, financing and other policies. These policies have been determined by the Board of Directors of Boston Properties, Inc., our sole general partner, and, in general, may be amended or revised from time to time by the Board of Directors.

7

Investment Policies

        Our investment objectives are to provide quarterly cash distributions to our securityholders and to achieve long-term capital appreciation through increases in the value of BPLP. We have not established a specific policy regarding the relative priority of these investment objectives.

        We expect to continue to pursue our investment objectives primarily through the ownership of our current properties and other acquired properties. We currently intend to continue to invest primarily in developments of commercial properties and acquisitions of existing improved properties or properties in need of redevelopment, and acquisitions of land which we believe have development potential, primarily in our four core markets—Boston, Washington, D.C., midtown Manhattan and San Francisco. Future investment or development activities will not be limited to a specified percentage of our assets. We intend to engage in such future investment or development activities in a manner that is consistent with the maintenance of Boston Properties, Inc.'s status as a REIT for federal income tax purposes. In addition, we may purchase or lease income-producing commercial and other types of properties for long-term investment, expand and improve the real estate presently owned or other properties purchased, or sell such real estate properties, in whole or in part, when circumstances warrant. We do not have a policy that restricts the amount or percentage of assets that will be invested in any specific property.

        We may also continue to participate with third parties in property ownership, through joint ventures or other types of co-ownership. Such investments may permit us to own interests in larger assets without unduly restricting diversification and, therefore, add flexibility in structuring our portfolio. We will not, however, enter into a joint venture or partnership to make an investment that would not otherwise meet our investment policies.

        Equity investments may be subject to existing mortgage financing and other indebtedness or such financing or indebtedness as may be incurred in connection with acquiring or refinancing these investments. Debt service on such financing or indebtedness will have a priority over any distributions with respect to our securities and the common stock of our general partner, Boston Properties, Inc. Investments are also subject to our policy not to be treated as an investment company under the Investment Company Act of 1940, as amended (the "1940 Act").

        While our current portfolio consists of, and our business objectives emphasize, equity investments in commercial real estate, we may, at the discretion of the Board of Directors of Boston Properties, Inc., invest in mortgages and other types of real estate interests consistent with Boston Properties, Inc.'s qualification as a REIT. We do not presently intend to invest in mortgages or deeds of trust, but may invest in participating or convertible mortgages if we conclude that we may benefit from the cash flow or any appreciation in value of the property. Investments in real estate mortgages run the risk that one or more borrowers may default under such mortgages and that the collateral securing such mortgages may not be sufficient to enable BPLP to recoup its full investment.

        Subject to the percentage of ownership limitations and gross income tests necessary for Boston Properties, Inc.'s REIT qualification, we also may invest in securities of other REITs, other entities engaged in real estate activities or securities of other issuers, including for the purpose of exercising control over such entities.

8

Dispositions

        Our disposition of properties is based upon management's periodic review of our portfolio and the determination by the Board of Directors of Boston Properties, Inc. that such action would be in the best interests of BPLP. Any decision to dispose of a property will be made by management of Boston Properties, Inc., as our general partner, and approved by a majority of the Board of Directors of Boston Properties, Inc. Some holders of our limited partnership interests, including Messrs. Mortimer B. Zuckerman and Edward H. Linde, would incur adverse tax consequences upon the sale of certain of our properties which differ from the tax consequences to us. Consequently such holders of our limited partnership interests may have different objectives regarding the appropriate pricing and timing of any such sale.

Financing Policies

        We do not have a policy limiting the amount of indebtedness that BPLP may incur. However, our mortgages, credit facilities and unsecured debt securities contain customary restrictions, requirements and other limitations on our ability to incur indebtedness. In addition, our agreement of limited partnership and the Certificate of Incorporation and Bylaws of Boston Properties, Inc. do not limit the amount or percentage of indebtedness that we may incur. We have not established any limit on the number or amount of mortgages that may be placed on any single property or on our portfolio as a whole.

        The Board of Directors of Boston Properties, Inc. will consider a number of factors when evaluating our level of indebtedness and when making decisions regarding the incurrence of indebtedness, including the purchase price of properties to be acquired with debt financing, the estimated market value of our properties upon refinancing and the ability of particular properties and BPLP as a whole to generate cash flow to cover expected debt service.

Policies with Respect to Other Activities

        Boston Properties, Inc., as our sole general partner, has the authority to issue additional common and preferred units of limited partnership interests of BPLP. Boston Properties, Inc. has in the past, and may continue in the future, to issue common or preferred units of limited partnership interests of BPLP to persons who contribute their direct or indirect interests in properties to us in exchange for such common or preferred units of limited partnership interest in BPLP. We have not engaged in trading, underwriting or agency distribution or sale of securities of issuers other than BPLP and we do not intend to do so. At all times, we intend to make investments in such a manner as to maintain Boston Properties, Inc.'s qualification as a REIT, unless because of circumstances or changes in the Internal Revenue Code of 1986, as amended (or the Treasury Regulations), the Board of Directors of Boston Properties, Inc. determines that it is no longer in the best interest of Boston Properties, Inc. to qualify as a REIT. We may make loans to third parties, including, without limitation, to joint ventures in which we participate. We intend to make investments in such a way that we will not be treated as an investment company under the 1940 Act. Our policies with respect to such activities may be reviewed and modified or amended from time to time by the Board of Directors of Boston Properties, Inc.

Competition

        We compete in the leasing of office and industrial space with a considerable number of other real estate companies, some of which may have greater marketing and financial resources. In addition, our hotel properties compete for guests with other hotels, some of which may have greater marketing and financial resources than are available to us and Marriott® International, Inc.

9


The Hotel Properties

        Effective July 1, 2002, we restructured the leases with respect to ownership of our three hotel properties by forming a taxable REIT subsidiary ("TRS"). The TRS, a wholly-owned subsidiary of BPLP, is the lessee pursuant to new leases for each of the hotel properties. As lessor, BPLP is entitled to a percentage of gross receipts from the hotel properties. Marriott® International, Inc. will continue to manage the hotel properties under the Marriott® name and under terms of the existing management agreements. The restructuring of the hotel leases allows all the economic benefits of ownership to flow to us.

Seasonality

        Our hotel properties traditionally have experienced significant seasonality in their operating income, with weighted-average net operating income (defined as revenues less operating expenses) by quarter over the year ended December 31, 2002 as follows:

First Quarter
   Second Quarter
   Third Quarter
   Fourth Quarter
13%   27%   28%   32%

RISK FACTORS

        Set forth below are the risks that we believe are material to holders of our securities. We refer to our common and preferred units of limited partnership as our "securities," and the investors who own securities as our "securityholders." This section contains some forward-looking statements. You should refer to the explanation of the qualifications and limitations on forward-looking statements beginning on page 22.

Our performance and value are subject to risks associated with our real estate assets and with the real estate industry.

        Our economic performance and the value of our real estate assets, and consequently the value of the securities, are subject to the risk that if our office, industrial, and hotel properties do not generate revenues sufficient to meet our operating expenses, including debt service and capital expenditures, our cash flow and ability to pay distributions to our securityholders will be adversely affected. The following factors, among others, may adversely affect the income generated by our office, industrial and hotel properties:

10

We are dependent upon the economic climates of our four core markets—Boston, Washington, D.C., midtown Manhattan and San Francisco.

        A majority of our revenues are derived from properties located in our four core markets: Boston, Washington, D.C., midtown Manhattan and San Francisco. As a result of the current slowdown in economic activity, there has been an increase in vacancy rates for office properties in these markets. A continued downturn in the economies of these markets, or the impact that the downturn in the overall national economy may have upon these economies, could result in further reduced demand for office space. Because our portfolio consists primarily of office buildings (as compared to a more diversified real estate portfolio), a decrease in demand for office space in turn could adversely affect our results from operations. Additionally, there are submarkets within our core markets that are dependent upon a limited number of industries. A significant downturn in one or more of these industries could also adversely affect our results of operations.

Our investment in property development may be more costly than anticipated.

        We have a significant development pipeline and intend to continue to develop and substantially renovate office, industrial and hotel properties. Our current and future development and construction activities may be exposed to the following risks:

Our use of joint ventures may limit our flexibility with jointly owned investments.

        In appropriate circumstances, we intend to develop and acquire properties in joint ventures with other persons or entities when circumstances warrant the use of these structures. We could become engaged in a dispute with any of our joint venturers which might affect our ability to operate a property. In addition, our joint venture partners may have different objectives than we do regarding the appropriate timing and pricing of any sale or refinancing of properties. Finally, in many instances, our

11


joint venture partners have competing interests in our markets that could create conflict of interest issues.

        In 2000, we entered into a joint venture with the New York State Common Retirement Fund which has agreed to contribute up to $270 million to acquire and develop properties with us. During the three-year investment period for this joint venture, which ends on May 12, 2003, the New York State Common Retirement Fund has the right to participate in all of our acquisition opportunities that meet agreed criteria and any development projects that we choose to pursue with an institutional partner. Its participation may limit our flexibility in acquiring properties or pursuing development projects.

We face risks associated with property acquisitions.

        Since the initial public offering of Boston Properties, Inc., our general partner, we have made acquisitions of large properties and portfolios of properties. We intend to continue to acquire properties and portfolios of properties, including large portfolios that could increase our size and result in alterations to our capital structure. Our acquisition activities and their success are subject to the following risks:

        We have acquired in the past and in the future may acquire properties or portfolios of properties through tax deferred contribution transactions in exchange for partnership interests in BPLP. This acquisition structure has the effect, among others, of reducing the amount of tax depreciation we can deduct over the tax life of the acquired properties, and typically requires that we agree to protect the contributors' ability to defer recognition of taxable gain through restrictions on our ability to dispose of the acquired properties and/or the allocation of partnership debt to the contributors to maintain their tax basis.

        We may acquire properties subject to liabilities and without any recourse, or with only limited recourse, with respect to unknown liabilities. As a result, if a liability were asserted against us based

12


upon ownership of those properties, we might have to pay substantial sums to settle it, which could adversely affect our cash flow. Unknown liabilities with respect to properties acquired might include:

We face potential difficulties or delays renewing leases or re-leasing space.

        We derive most of our income from rent received from our tenants. If a tenant experiences a downturn in its business or other types of financial distress, it may be unable to make timely rental payments. Also, when our tenants decide not to renew their leases or terminate early, we may not be able to re-lease the space. Even if tenants decide to renew, the terms of renewals or new leases, including the cost of required renovations or concessions to tenants, may be less favorable than current lease terms. As a result, our cash flow could decrease and our ability to make distributions to our securityholders could be adversely affected.

We face potential adverse effects from major tenants' bankruptcies or insolvencies.

        The bankruptcy or insolvency of a major tenant may adversely affect the income produced by our properties. Our tenants could file for bankruptcy protection or become insolvent in the future. We cannot evict a tenant solely because of its bankruptcy. On the other hand, a bankrupt tenant may reject and terminate its lease with us. In such case, our claim against the bankrupt tenant for unpaid and future rent would be subject to a statutory cap that might be substantially less than the remaining rent actually owed under the lease, and, even so, our claim for unpaid rent would likely not be paid in full. This shortfall could adversely affect our cash flow and results of operations.

We may have difficulty selling our properties which may limit our flexibility.

        Large and high quality office, industrial and hotel properties like the ones that we own could be difficult to sell. This may limit our ability to change our portfolio promptly in response to changes in economic or other conditions. In addition, federal tax laws limit our ability to sell properties that we have owned for fewer than four years and this may affect our ability to sell properties without adversely affecting our ability to pay distributions to our securityholders. These restrictions reduce our ability to respond to changes in the performance of our investments and could adversely affect our financial condition and results of operations.

        Our ability to dispose of some of our properties is constrained by their tax attributes. Properties which we developed and have owned for a significant period of time or which we acquired through tax deferred contribution transactions in exchange for partnership interests in BPLP often have a low tax basis. If we dispose of these properties outright in taxable transactions, we will recognize a significant amount of taxable gain, which in turn would impact our cash flow under the requirements of the Internal Revenue Code for REIT's like Boston Properties, Inc. In some cases, we are restricted from disposing of properties contributed in exchange for our partnership interests under tax protection agreements with contributors. To dispose of low basis or tax-protected properties efficiently we often use like-kind exchanges, which qualify for non-recognition of taxable gain, but can be difficult to consummate and result in the property for which the disposed assets are exchanged inheriting their low basis and other tax attributes (including tax protection covenants).

13


Our properties face significant competition.

        We face significant competition from developers, owners and operators of office, industrial and other commercial real estate, including sublease space available from our tenants. Substantially all of our properties face competition from similar properties in the same market. Such competition may affect our ability to attract and retain tenants and may reduce the rents we are able to charge. These competing properties may have vacancy rates higher than our properties, which may result in their owners being willing to make space available at lower prices than the space in our properties.

Because we own three hotel properties, we face the risks associated with the hospitality industry.

        We own three hotel properties which we lease to our taxable REIT subsidiary, or TRS. BPLP, as lessor, is entitled to a percentage of the gross receipts of our hotel properties and Marriott International, Inc. manages our hotel properties under the Marriott® name pursuant to a management contract with the TRS as lessee. While the TRS structure allows the economic benefits of ownership to flow to us, the TRS is subject to tax on its income from the operations of the hotels at the federal and state level. In addition changes in applicable tax laws may require us to modify the structure for owning our hotel properties, and such changes may adversely affect the cash flows from our hotels.

        Because the lease payments we receive under the hotel leases are based on a participation in the gross receipts of the hotels, if the hotels do not generate sufficient receipts, our cash flow would be decreased, which could reduce the amount of cash available for distributions to our securityholders. The following factors, among others, are common to the hotel industry, and may reduce the receipts generated by our hotel properties:

        In addition, because all three of our hotel properties are located within a two-mile radius in downtown Boston and Cambridge, they are all subject to the Boston market's fluctuations in demand, increases in operating costs and increased competition from additions in supply.

Compliance or failure to comply with the Americans with Disabilities Act and other similar laws could result in substantial costs.

        The Americans with Disabilities Act generally requires that public buildings, including office buildings and hotels, be made accessible to disabled persons. Noncompliance could result in the imposition of fines by the federal government or the award of damages to private litigants. If, pursuant to the Americans with Disabilities Act, we are required to make substantial alterations and capital expenditures in one or more of our properties, including the removal of access barriers, it could adversely affect our financial condition and results of operations, as well as the amount of cash available for distributions to our securityholders.

        We may also incur significant costs complying with other regulations. Our properties are subject to various federal, state and local regulatory requirements, such as state and local fire and life safety requirements. If we fail to comply with these requirements, we could incur fines or private damage awards. We believe that our properties are currently in material compliance with all of these regulatory

14


requirements. However, we do not know whether existing requirements will change or whether compliance with future requirements will require significant unanticipated expenditures that will affect our cash flow and results of operations.

Some potential losses are not covered by 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. We believe all of our properties are adequately insured. The property insurance that we maintain for our properties has historically been on an "all risk" basis, which until 2002 included losses caused by acts of terrorism. Following the terrorist activity of September 11, 2001 and the resulting uncertainty in the insurance market, insurance companies generally excluded insurance against acts of terrorism from their "all risk" policies. As a result our "all risk" insurance coverage currently contains specific exclusions for losses attributable to acts of terrorism. In light of this development, in 2002 we purchased stand-alone terrorism insurance on a portfolio-wide basis with annual aggregate limits that we consider commercially reasonable, considering the availability and cost of such coverage. The federal Terrorism Risk Insurance Act, enacted in November 2002, requires regulated insurers to make available coverage for certified acts of terrorism (as defined by the statute) under property insurance policies, but we cannot currently anticipate whether the scope and cost of such coverage will compare favorably to stand-alone terrorism insurance, and thus whether it will be commercially reasonable for us to change our coverage for acts of terrorism going forward. We will continue to monitor the state of the insurance market, but we do not currently expect that coverage for acts of terrorism on terms comparable to pre-2002 policies will become available on commercially reasonable terms.

        We 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. However, 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 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 insurance subsidiary, IXP, Inc. ("IXP"), to act as a captive insurance company and be one of the elements of our overall insurance program. IXP has acted as a reinsurer for our primary carrier with respect to a portion of our earthquake insurance coverage for our Greater San Francisco properties. In the future IXP may provide additional or different coverage, as a reinsurer or a primary insurer, depending on the availability and cost of third party insurance in the marketplace and the level of self insurance that we believe is commercially reasonable.

        There are other types of losses, such as from wars, acts of bio-terrorism or the presence of mold at our properties, for which we cannot obtain insurance at all or at a reasonable cost. With respect to such losses and losses from acts of terrorism, earthquakes or other catastrophic events, if we experience a loss that is uninsured or that exceeds policy limits, we could lose the capital invested in the damaged properties, as well as the anticipated future revenues from those properties. Depending on the specific circumstances of each affected property, it is possible that we could be liable for mortgage indebtedness or other obligations related to the property. Any such loss could materially and adversely affect our business and financial condition and results of operations.

15


Potential liability for environmental contamination could result in substantial costs.

        Under federal, state and local environmental laws, ordinances and regulations, we may be required to investigate and clean up the effects of releases of hazardous or toxic substances or petroleum products at our properties simply because of our current or past ownership or operation of the real estate. If unidentified environmental problems arise, we may have to make substantial payments which could adversely affect our cash flow and our ability to make distributions to our securityholders because:

16

        These costs could be substantial and in extreme cases could exceed the value of the contaminated property. The presence of hazardous or toxic substances or petroleum products or the failure to properly remediate contamination may materially and adversely affect our ability to borrow against, sell or rent an affected property. In addition, applicable environmental laws create liens on contaminated sites in favor of the government for damages and costs it incurs in connection with a contamination. Changes in laws increasing the potential liability for environmental conditions existing at our properties, or increasing the restrictions on the handling, storage or discharge of hazardous or toxic substances or petroleum products or other actions may result in significant unanticipated expenditures.

        Environmental laws also govern the presence, maintenance and removal of asbestos. Such laws require that owners or operators of buildings containing asbestos:

        Such laws may impose fines and penalties on building owners or operators who fail to comply with these requirements and may allow third parties to seek recovery from owners or operators for personal injury associated with exposure to asbestos fibers. Some of our properties are located in urban, industrial and previously developed areas where fill or current or historic industrial uses of the areas have caused site contamination.

        It is our policy to retain independent environmental consultants to conduct Phase I environmental site assessments and asbestos surveys with respect to our acquisition of properties. These assessments generally include a visual inspection of the properties and the surrounding areas, an examination of current and historical uses of the properties and the surrounding areas and a review of relevant state, federal and historical documents, but do not involve invasive techniques such as soil and ground water sampling. Where appropriate, on a property-by-property basis, our practice is to have these consultants conduct additional testing, including sampling for asbestos, for lead in drinking water, for soil contamination where underground storage tanks are or were located or where other past site usages create a potential environmental problem, and for contamination in groundwater. Even though these environmental assessments are conducted, there is still the risk that:

        While we test indoor air quality on a regular basis and have an ongoing maintenance program in place to address this aspect of property operations, inquiries about indoor air quality may necessitate special investigation and, depending on the results, remediation. Indoor air quality issues can stem from inadequate ventilation, chemical contaminants from indoor or outdoor sources, and biological contaminants such as molds, pollen, viruses and bacteria. Indoor exposure to chemical or biological contaminants above certain levels can be alleged to be connected to allergic reactions or other health effects and symptoms in susceptible individuals. If these conditions were to occur at one of our properties, we may need to undertake a targeted remediation program, including without limitation,

17


steps to increase indoor ventilation rates and eliminate sources of contaminants. Such remediation programs could be costly, necessitate the temporary relocation of some or all of the property's tenants or require rehabilitation of the affected property.

We face risks associated with the use of debt to fund acquisitions and developments, including refinancing risk.

        We are subject to the risks normally associated with debt financing, including the risk that our cash flow will be insufficient to meet required payments of principal and interest. We anticipate that only a small portion of the principal of our debt will be repaid prior to maturity. Therefore, we are likely to need to refinance at least a portion of our outstanding debt as it matures. There is a risk that we may not be able to refinance existing debt or that the terms of any refinancing will not be as favorable as the terms of our existing debt. If principal payments due at maturity cannot be refinanced, extended or repaid with proceeds from other sources, such as new equity capital, our cash flow will not be sufficient to repay all maturing debt in years when significant "balloon" payments come due.

        We have agreements with a number of limited partners of BPLP who contributed properties in exchange for partnership interests that require BPLP to maintain secured debt on certain of our assets and/or allocate partnership debt to such limited partners to enable them to continue to defer recognition of their taxable gain with respect to the contributed property. These tax protection and debt allocation agreements may restrict our ability to repay or refinance debt.

An increase in interest rates would increase our interest costs on variable rate debt and could adversely impact our ability to refinance existing debt.

        We currently have, and may incur more, indebtedness that bears interest at variable rates. Accordingly, if interest rates increase, so will our interest costs, which would adversely affect our cash flow and our ability to pay principal and interest on our debt and our ability to make distributions to our securityholders. Further, rising interest rates could limit our ability to refinance existing debt when it matures. As a protection against rising interest rates, we enter into agreements such as interest rate swaps, caps, floors and other interest rate hedging contracts.

Covenants in our debt agreements could adversely affect our financial condition.

        The mortgages on our properties contain customary covenants such as those that limit our ability, without the prior consent of the lender, to further mortgage the applicable property or to discontinue insurance coverage. Our credit facilities and unsecured debt securities contain customary restrictions, requirements and other limitations on our ability to incur indebtedness, including total debt to asset ratios, secured debt to total asset ratios, debt service coverage ratios and minimum ratios of unencumbered assets to unsecured debt which we must maintain. Our continued ability to borrow under our credit facilities is subject to compliance with our financial and other covenants. In addition, our failure to comply with such covenants could cause a default under the applicable debt agreement, and we may then be required to repay such debt with capital from other sources. Under those circumstances, other sources of capital may not be available to us, or be available only on unattractive terms.

        Our "all risk" insurance policies contain exclusions for acts of terrorism and some of our lenders may take the position that our insurance coverage against acts of terrorism no longer complies with covenants in our debt agreements. Additionally, in the future our ability to obtain debt financing, or the terms of such financing, may be adversely affected if lenders generally insist upon greater insurance coverage against acts of terrorism than is available to us in the marketplace on commercially reasonable terms.

18


        We rely on debt financing, including borrowings under our credit facilities, issuances of unsecured debt securities and debt secured by individual properties, to finance our acquisition and development activities and for working capital. If we are unable to obtain debt financing from these or other sources, or to refinance existing indebtedness upon maturity, our financial condition and results of operations would likely be adversely affected. If we breach covenants in our debt agreements, the lenders can declare a default and, if the debt is secured, can take possession of the property securing the defaulted loan. In addition, our unsecured debt agreements contain specific cross-default provisions with respect to specified other indebtedness, giving the unsecured lenders the right to declare a default if we are in default under other loans in some circumstances. Defaults under our debt agreements could materially and adversely affect our financial condition and results of operations.

Our degree of leverage could limit our ability to obtain additional financing or affect the market price of the debt securities.

        Debt to market capitalization ratio is a measure of our total debt as a percentage of the aggregate of our total debt plus the market value of the outstanding common stock of Boston Properties, Inc. and interests in BPLP. Our debt to market capitalization ratio was approximately 52.8% as of December 31, 2002. Our degree of leverage could affect our ability to obtain additional financing for working capital, capital expenditures, acquisitions, development or other general corporate purposes. Our senior unsecured debt is currently rated investment grade by the three major rating agencies. However, there can be no assurance we will be able to maintain this rating, and in the event our senior debt is downgraded from its current rating, we would likely incur higher borrowing costs. Our degree of leverage could also make us more vulnerable to a downturn in business or the economy generally.

Failure of Boston Properties, Inc. to qualify as a REIT would have a material adverse effect on BPLP.

        BPLP, in general, and the holders of our securities, in particular, must rely on Boston Properties, Inc., as our general partner, to manage the affairs and business of BPLP. Boston Properties, Inc. is subject to certain risks that may affect its financial and other conditions, including particularly adverse consequences if it fails to qualify as a REIT for federal income tax purposes. We believe that Boston Properties, Inc. is organized and qualified as a REIT, and intends to operate in a manner that will allow it to continue to qualify as a REIT. However, we cannot assure you that Boston Properties, Inc. will remain qualified as such in the future. This is because qualification as a REIT involves the application of highly technical and complex provisions of the Internal Revenue Code as to which there are only limited judicial and administrative interpretations, and involves the determination of facts and circumstances not entirely within our control. In addition, future legislation, new regulations, administrative interpretations or court decisions may significantly change the tax laws or the application of the tax laws with respect to qualification as a REIT for federal income tax purposes or the federal income tax consequences of such qualification. If Boston Properties, Inc. fails to qualify as a REIT, it will face serious tax consequences which will directly and adversely impact BPLP and may substantially reduce the funds available for payment of distributions to our securityholders.

In order to maintain the REIT status of our general partner, Boston Properties, Inc., we may be forced to borrow funds on a short-term basis during unfavorable market conditions.

        In order to maintain the REIT status of our general partner, Boston Properties, Inc., we may need to borrow funds on a short-term basis to meet the REIT distribution requirements, even if the then prevailing market conditions are not favorable for these borrowings. To qualify as a REIT, Boston Properties, Inc. generally must distribute to its stockholders at least 90% of its net taxable income each year, excluding capital gains. In addition, Boston Properties, Inc. will be subject to a 4% nondeductible excise tax on the amount, if any, by which dividends paid by it in any calendar year are less than the sum of 85% of its ordinary income, 95% of its capital gain net income and 100% of its undistributed

19


income from prior years. Boston Properties, Inc. may need short-term debt to fund required distributions as a result of differences in timing between the actual receipt of income and the recognition of income for federal income tax purposes, or the effect of non-deductible capital expenditures, the creation of reserves or required debt or amortization payments.

Limits on changes in control of Boston Properties, Inc., our general partner, may discourage takeover attempts beneficial to our securityholders.

        Provisions in Boston Properties, Inc.'s certifcate of incorporation, bylaws and shareholder rights agreement, and provisions in our agreement of limited partnership, as well as provisions of the Internal Revenue Code and Delaware corporate law, may:

        Primarily to facilitate maintenance of Boston Properties, Inc.'s qualification as a REIT, its certificate of incorporation generally prohibits ownership, directly, indirectly or beneficially, by any single stockholder of more than 6.6% of the number of outstanding shares of any class or series of its equity stock. We refer to this limitation as the "ownership limit." The Board of Directors of Boston Properties, Inc. may waive or modify the ownership limit with respect to one or more persons if it is satisfied that ownership in excess of this limit will not jeopardize the status of Boston Properties, Inc. as a REIT for federal income tax purposes. In addition, under Boston Properties, Inc.'s certificate of incorporation, each of Mortimer B. Zuckerman and Edward H. Linde, along with their respective families and affiliates, as well as, in general, pension plans and mutual funds, may actually and beneficially own up to 15% of the number of outstanding shares of any class of securities of Boston Properties, Inc.'s equity stock. Shares owned in violation of the ownership limit will be subject to the loss of rights to distributions and voting and other penalties. The ownership limit may have the effect of inhibiting or impeding a change in control.

        We have agreed in our agreement of limited partnership that Boston Properties, Inc., our general partner, will not engage in business combinations unless our limited partners other than Boston Properties, Inc. receive, or have the opportunity to receive, the same consideration for their limited partnership interests as holders of Boston Properties, Inc.'s common stock in the transaction. If these limited partners do not receive such consideration, Boston Properties, Inc. cannot engage in the transaction unless 75% of these limited partners vote to approve the transaction. In addition, we have agreed in our agreement of limited partnership that Boston Properties, Inc., as our general partner, will not consummate business combinations in which it received the approval of its stockholders unless these limited partners are also allowed to vote and the transaction would have been approved had these limited partners been able to vote as stockholders on the transaction. Therefore, if the stockholders of Boston Properties, Inc. approve a business combination that requires a vote of stockholders, our agreement of limited partnership requires the following before Boston Properties, Inc. can consummate the transaction:

20

        As a result of these provisions, a potential acquirer may be deterred from making an acquisition proposal and Boston Properties, Inc. may be prohibited by contract from engaging in a proposed business combination even though its stockholders approve of the combination.

        Boston Properties, Inc. has adopted a shareholder rights plan. Under the terms of this plan, Boston Properties, Inc. can in effect prevent a person or group from acquiring more than 15% of the outstanding shares of its common stock, because, unless it approves of the acquisition, after the person acquires more than 15% of the outstanding common stock of Boston Properties, Inc., all other stockholders will have the right to purchase securities from Boston Properties, Inc. at a price that is less than their then fair market value, which would substantially reduct the value and influence of stock owned by the acquiring person. The Board of Dirctors of Boston Properties, Inc. can prevent the plan from operating by approving the transaction in advance, which gives Boston Properties, Inc. significant power to approve or disapprove of the efforts of a person or group to acquire a large interest in Boston Properties, Inc.

We may change our policies without obtaining approval of our securityholders.

        Our operating and financial policies, including our policies with respect to acquisitions, growth, operations, indebtedness, capitalization and distributions, are determined by our sole general partner, Boston Properties, Inc. Accordingly, our securityholders will have little direct control over these policies.

Our success depends on key personnel whose continued service is not guaranteed.

        We depend on the efforts of key personnel, particularly Mortimer B. Zuckerman, Chairman of the board of directors of Boston Properties, Inc., and Edward H. Linde, our President and Chief Executive Officer of Boston Properties, Inc. Among the reasons that Messrs. Zuckerman and Linde are important to our success is that each has a national reputation which attracts business and investment opportunities and assists us in negotiations with lenders. If we lost their services, our relationships with lenders, potential tenants and industry personnel would diminish. Mr. Zuckerman has substantial outside business interests which could interfere with his ability to devote his full time to our business and affairs.

        The two Executive Vice Presidents, Chief Financial Officer and other executive officers of Boston Properties, Inc. who serve as managers of our regional offices have strong reputations. Their reputations aid us in identifying opportunities, having opportunities brought to us, and negotiating with tenants and build-to-suit prospects. While we believe that we could find replacements for these key personnel, the loss of their services could materially and adversely affect our operations because of diminished relationships with lenders, prospective tenants and industry personnel.

Conflicts of interest exist with holders of our limited partnership interests.

        Some holders of our limited partnership interests, including Messrs. Zuckerman and Linde, would incur adverse tax consequences upon the sale of certain of our properties and on the repayment of related debt which differ from the tax consequences to us. Consequently, such holders of our limited partnership interests may have different objectives regarding the appropriate pricing and timing of any such sale or repayment of debt. While Boston Properties, Inc. has exclusive authority under our limited partnership agreement to determine when to refinance or repay debt or whether, when, and on what terms to sell a property, subject, in the case of certain properties to the contractual commitments

21


described below, any such decision would require the approval of Boston Properties, Inc.'s board of directors. As directors and executive officers of Boston Properties, Inc., Messrs. Zuckerman and Linde have substantial influence with respect to any such decision. Their influence could be exercised in a manner inconsistent with the interests of some of our other securityholders, including in a manner which could prevent completion of a sale of a property or the repayment of indebtedness.

        Under the terms of our limited partnership agreement, we have agreed not to sell or otherwise transfer some of our properties, prior to specified dates, in any transaction that would trigger taxable income, without first obtaining the consent of Messrs. Zuckerman and Linde. However, we are not required to obtain their consent if, during the applicable period, each of them does not hold at least 30% of his original interest in BPLP, or if those properties are transferred in a nontaxable event. In addition, we have entered into similar agreements with respect to other properties that we have acquired in exchange for our limited partnership interests. Pursuant to those agreements, we are responsible for the reimbursement of tax costs to the prior owners if the subject properties are sold in a taxable sale. Our obligations to the prior owners are generally limited in time and only apply to actual damages suffered. As of December 31, 2002, there were a total of 34 properties subject to these restrictions, and those 34 properties and 2 additional properties sold during 2002, are estimated to have accounted for approximately 54.6% of our total revenue for the year ended December 31, 2002.

        We have also entered into agreements providing prior owners with the right to guarantee specific amounts of indebtedness and, in the event that the specific indebtedness they guarantee is repaid or reduced, additional and/or substitute indebtedness. These agreements may hinder actions that we may otherwise desire to take to repay or refinance guaranteed indebtedness because we would be required to make payments to the beneficiaries of such agreements if we violate these agreements.

        Messrs. Zuckerman and Linde have a broad and varied range of investment interests. Either one could acquire interest in a company which is not currently involved in real estate investment activities but which may acquire real property in the future. However, pursuant to each of their employment agreements, Messrs. Zuckerman and Linde will not, in general, have management control over such companies, and therefore, they may not be able to prevent one or more such companies from engaging in activities that are in competition with our activities.

We did not obtain new owner's title insurance policies in connection with properties acquired during the initial public offering of Boston Properties, Inc.

        We acquired many of our properties from our predecessors at the completion of the initial public offering of Boston Properties, Inc., our sole general partner, in June 1997. Before we acquired these properties each of them was insured by a title insurance policy. We did not, however, obtain new owner's title insurance policies in connection with the acquisition of these properties. Nevertheless, because in many instances we acquired these properties indirectly by acquiring ownership of the entity which owned the property and those owners remain in existence as our subsidiaries, some of these title insurance policies may continue to benefit us. Many of these title insurance policies may be for amounts less than the current values of the applicable properties. If there was a title defect related to any of these properties, or to any of the properties acquired at the time of our initial public offering, that is no longer covered by a title insurance policy, we could lose both our capital invested in and our anticipated profits from such property. We have obtained title insurance policies for all properties that we have acquired after the initial public offering of Boston Properties, Inc.

22


We face possible adverse changes in tax laws.

        From time to time changes in state and local tax laws or regulations are enacted, which may result in increase in our tax liability. The shortfall in tax revenues for states and municipalities in recent years may lead to an increase in the frequency and size of such changes. We also face the risk that tax authorities may challenge certain aspects of our acquisition, operation or disposition of properties. If such challenges are successful, we may be required to pay additional taxes on our assets or income and may be assessed interest and penalties on such additional taxes. These increased tax costs could adversely affect our financial condition and results of operations and our ability to make interest payments to holders of the notes.

Management's Discussion and Analysis of Financial Condition and Results of Operation

        The following discussion should be read in conjunction with the financial statements and notes thereto appearing elsewhere in this report.

Forward Looking Statements

        This Form 10 contains forward-looking statements within the meaning of the federal securities laws, principally, but not only, under the captions "Business and Growth Strategies," "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations." We caution investors that any forward-looking statements in this Form 10, or which management may make orally or in writing from time to time, are based on management's beliefs and on 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. We expressly disclaim any responsibility to update our forward-looking statements, whether as a result of new information, future events or otherwise. Accordingly, investors should use caution in relying on past 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:

25

        The risks included here are not exhaustive. Other sections of this Form 10 may include additional factors which 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 such risk factors, nor can we assess the impact of all such 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 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, or Boston Properties, Inc., our general partner, may furnish to the public from time to time through Forms 8-K or otherwise.

Critical Accounting Policies

        The SEC published cautionary advice in December 2001 regarding MD&A disclosure of critical accounting policies. The significant accounting policies are also discussed in Note 1 of our financial statements. These critical accounting policies are subject to judgments and uncertainties, which affect the application of these policies. We base our estimates on historical experience and on various other assumptions believed to be reasonable under the circumstances. On an on-going basis, we evaluate our estimates. In the event estimates or assumptions prove to be different from actual results, adjustments are made in subsequent periods to reflect more current information. The material accounting policies that we believe are most critical to the understanding of our financial position and results of operations that require significant management estimates and judgments are discussed below.

Real Estate

        Real estate is stated at depreciated cost. The cost of buildings and improvements include the purchase price of property, legal fees and 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.

        We periodically review our properties to determine if our carrying amounts will be recovered from future operating cash flows. The evaluation of anticipated cash flows is highly subjective and is based in part on assumptions regarding future occupancy, rental rates and capital requirements which 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 FAS 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 or disposal date, an impairment loss may be recognized. 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.

        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 judgment. Our capitalization policy on our development properties is guided by SFAS No. 34 "Capitalization of Interest Cost" and SFAS No. 67 "Accounting for Costs and the Initial Rental Operations of Real Estate Properties," and ceases capitalization when the property is held available for occupancy upon substantial completion of tenant improvements, but no later than one year from the completion of major construction activity. In the third quarter of 2002, we substantially completed construction of the base building at 611 Gateway in South San Francisco. Although substantial construction remained which would allow continued capitalization until the earlier of completion of tenant build-out or one-year, and since we have no leasing prospects and do not

26


expect to lease the property within the next year, the building was placed in-service during the third quarter of 2002. Accordingly, since July 2002 all costs are being expensed as incurred.

Investments in Unconsolidated Joint Ventures

        We account for our investments in unconsolidated 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, the net equity investment is reflected on our consolidated balance sheets, and our share of net income or loss from the joint ventures is included on our consolidated statements of operations. The joint venture agreements may designate different percentage allocations among the investors for profits and losses, however our recognition of joint venture income or loss generally follows the joint ventures' distribution priorities, which may change upon the achievement of certain investment return thresholds.

        We serve as the development manager for the joint ventures currently under development. The profit on development fees received from joint ventures is recognized to the extent attributable to the outside interests in the joint ventures, in addition to internal costs.

Revenue Recognition

        Base rental revenue is reported on a straight-line basis over the terms of our respective leases. Accrued rental income represents rental income earned in excess of rent payments 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 December 31, 2002. The credit risk is mitigated by the high quality of our tenant base, review of the tenant's risk profile prior to lease execution and continual monitoring of our portfolio to identify potential problem tenants.

        Property operating cost reimbursements due from tenants for common area maintenance, real estate taxes and other recoverable costs are recognized in the period that expenses are incurred.

        Development fees are recognized ratably over the period of development, as earned. Management fees are recognized as revenue as they are earned.

        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.

27


Depreciation

        We compute depreciation on our properties using the straight line method based on an estimated useful life of 40 years. The portion of the acquisition cost allocated between land and building each property may vary based on estimated land value and other factors. The allocation of the acquisition cost to building and the determination of the useful life are based on management's estimates of the composite life of the building.

Fair Value of Financial Instruments

        On a quarterly basis, we calculated the fair value of our mortgage debt and unsecured notes. We discount the spread between the future contractual interest payments and future interest payments on our mortgage debt and unsecured notes based on a current market rate. In determining the current market rate, we add a market spread to the quoted yields on federal government treasury securities with similar maturity dates to our own debt. In addition, we are also required to adjust the carrying values of our derivative contracts on a quarterly basis to its fair value. Because our valuations of our financial instruments are based on these types of estimates, the fair value of our financial instruments may change if our estimates do not turn out to be accurate.

Overview

        Notwithstanding a decrease in tenant demand and higher reported vacancy rates, which have been impacted by stagnant job growth and the substantial supply of sub-lease space brought back to market due to overzealous expectations of economic growth which did not materialize, we produced a solid operating performance in 2002, increasing diluted earnings per share, excluding gains on sales of properties, by 13.8% on a year-to year basis. Highlights of the 2002 operating performance include:

        During 2002, we added 4.5 million net rentable square feet to our portfolio by completing an acquisition totaling approximately $1.06 billion and completing developments totaling approximately $924.0 million. In addition, as of December 31, 2002, we had construction in progress representing a total anticipated investment of approximately $924.0 million and a total of approximately 2.8 million net rentable square feet.

        Also in 2002, we sold seven properties and other real estate totaling 1.5 million net rentable square feet. We received gross proceeds from the sale of this real estate of approximately $428.0 million. On the 2.7 million net rentable square feet of second generation space renewed or re-leased during the year, new net rents were on average approximately 6.8% higher than the expiring net rents. At December 31, 2002, our in-service portfolio was 93.9% occupied.

        The difficulties and uncertainties characterizing the economy since 2001 still prevail and there is no sign yet of the job growth necessary for increasing office space demand. It is worth noting that, in this real estate cycle, previous over-commitments to space by tenants, particularly among technology companies, had an unprecedented role in subsequently rising vacancy rates while excessive speculative construction played a much lesser role, and that the market responded quickly to declining demand with a halt in almost all new construction. While this bodes well for the future, we do not foresee a significant improvement in the market in 2003. Decreased tenant activity makes it unlikely that

28


occupancy rates will increase this year, and since there will be no shortage of opportunities for tenants, increases in market rents are unlikely, with further declines possible. As a consequence we expect little or no growth in 2003 in the income generated within our portfolio.

        One of our focuses for 2003 is completing the leasing of three development projects recently put into service or still under construction. Two suburban projects with 555,000 net rentable square feet in total and base building construction completed, Waltham Weston Corporate Center in Waltham, Massachusetts, and 611 Gateway Center in south San Francisco, California, are impacted by low market demand and will not achieve stabilization for several years. The third project is Times Square Tower, a 47 story, 1.2 million net rentable square foot building currently under construction in New York City at the heart of Times Square. Arthur Andersen LLP had originally been secured as lead tenant for this property, which is now being actively re-marketed after the termination of the Arthur Andersen lease in the wake of that firm's demise last year. A 207,000 square foot lease with a major law firm was signed in January 2003, and we are very encouraged by the considerable additional active tenant interest in this property, but with initial occupancy not scheduled until 2004, Times Square Tower will of course not contribute to 2003 earnings.

        Our successful issuance of unsecured long- term debt, while beneficial overall in obtaining long-term fixed-rate investment grade debt, will negatively affect earnings for 2003 compared to last year. This fixed rate debt replaced floating rate construction financing in place during 2002 to fund development projects and part of the floating rate bridge financing that initially funded the acquisition of 399 Park Avenue. Thus our debt in 2003, by the nature of the yield curve, will be at measurably higher interest rates. This matching of long-term fixed rate financing to the long-term duration of our leases represents an appropriately prudent financial structure, but the impact will be some reduction in comparable net income.

Results of Operations

        The following discussion is based on our consolidated financial statements for the years ended December 31, 2002, 2001 and 2000.

        As of July 1, 2002, we reported the gross operating revenues and expenses associated with our ownership of the hotels by our TRS on a consolidated basis, whereas in the past, we only reported net lease payments and real estate taxes. The reporting of the hotel operations for the year ended December 31, 2002 is not directly comparable to the same period in 2001 and therefore the hotel operating expenses have been netted against hotel revenues for the year ended December 31, 2002 (otherwise entitled "Hotel Net Operating Income") to provide a basis of comparison to prior periods.

        As of December 31, 2002 and 2001, we owned 142 properties and 147 properties, respectively (we refer to all of the properties that we own as our "Total Portfolio"). Our property operations, including property management, development and leasing are regionally aligned with the objective of becoming the dominant landlord in our core markets. Management reviews operating and financial data for each property separately and independently from all other properties. Major decisions regarding the allocation of financing, investing, information technology and capital allocation are made in conjunction with the input of senior management located in our corporate headquarters.

        As a result of changes in 2002 within our Total Portfolio, the financial data presented below shows significant changes in revenues and expenses from period to period. We do not believe our period to period financial data are comparable. Therefore, the comparison of operating results for the years ended December 31, 2002, 2001 and 2000 show changes resulting from properties that we owned for each period compared (we refer to this comparison as our "Same Property Portfolio" for the applicable period) and the changes attributable to our Total Portfolio.

29


Comparison of the year ended December 31, 2002 to the year ended December 31, 2001

        The table below shows selected operating information for the Same Property Portfolio and the Total Portfolio. The Same Property Portfolio consists of 119 properties, including three hotels and five properties in which we have a joint venture interest, acquired or placed in service on or prior to January 1, 2001 and owned by us through December 31, 2002. The Total Property Portfolio includes the effect of the other properties either placed in service or acquired after January 1, 2001 or disposed of on or prior to December 31, 2002. Our net property operating margins, which are defined as rental revenues less operating expenses exclusive of the three hotel properties for the year ended December 31, 2002, have ranged between 67% and 70%.

Rental Revenue

        The increase in rental revenue of $165.9 million in the Total Portfolio, which includes an increase in straight line rent of approximately $23.0 million, primarily relates to new leases signed and in place at December 31, 2002 in connection with the acquisition of Citigroup Center in the second quarter of 2001 and the acquisition of 399 Park Avenue in the third quarter of 2002, the commencement of occupancy at 111 Huntington Avenue in the fourth quarter of 2001 and the placing into service of Five Times Square in the first quarter of 2002. These events increased revenue by $194.5 million. This increase was offset by dispositions of properties throughout 2002 and a decrease in occupancy rates from 95.3% at December 31, 2001 to 93.9% at December 31, 2002. Properties sold during 2002 included One and Two Independence Square, 2391 West Winton Avenue, Fullerton Square, and 7600, 7700 and 7702 Boston Boulevard.

30


Termination Income

        The termination income for the year ended December 31, 2002 was primarily related to three tenants in San Francisco who terminated their leases and made termination payments totaling approximately $4.0 million. This compared to termination income received in the prior year related to the early surrender of space of one tenant in New York representing $12.4 million.

Development and Management Services

        The decrease in development and management income of $1.4 million primarily resulted from the completion of projects during 2001, including certain third party contracts as well as certain of our joint venture projects. This decrease was offset by development fees earned on a new joint venture project which was started in 2002 as well as an increase in management fees relating to certain of our joint ventures which were placed into service in 2002.

Interest and Other

        The decrease in interest and other expenses related to the Total Portfolio is a result of less interest earned due to lower average cash balances maintained and lower interest rates on cash balances during the year ended December 31, 2002 as compared to the year ended December 31, 2001. During the year ended December 31, 2001, the higher average cash balance was attributable to unused proceeds from an equity public offering by Boston Properties, Inc. of its common stock in October 2000 which proceeds were contributed to us.

Operating Expenses

        Property operating expenses (real estate taxes, utilities, insurance, repairs and maintenance, cleaning and other property-related expenses) in the Same Property Portfolio increased during the year ended December 31, 2002 primarily due to increases in real estate taxes of $5.2 million, or 5.0%, and increases in insurance of $4.1 million, or 70.6%. The increase in real estate taxes was primarily due to higher property tax assessments. Small increases in the other property operating expenses account for the remaining difference. Additional increases in property operating expenses in the Total Property Portfolio were primarily due to the additions of the Citigroup Center, Five Times Square, 399 Park Avenue and 111 Huntington Avenue properties and other properties that we acquired or placed in service after January 1, 2001. Increases in insurance in the Same Property Portfolio and Total Portfolio are related to increases in rates on existing coverage and the purchase of a separate stand-alone terrorism policy. The office leases include reimbursements from tenants for a portion of these operating expenses. The increases were offset by decreases related to properties that were sold during 2002.

Hotel Net Operating Income

        Net operating income for the hotel properties decreased by $3.5 million or approximately 13.0% for the year ended December 31, 2002 compared to the year ended December 31, 2001. Average occupancy and Revenue per Available Room ("REVPAR") for the hotel properties were 80.7% and $146.25, respectively, for the year ended December 31, 2002 compared to 80.5% and $158.50, respectively, for the prior year. This is related to the general downturn in the economy as well as lasting effects of the terrorist attack on September 11, 2001.

Other Expenses

        General and administrative expenses in the Total Portfolio increased during the year ended December 31, 2002 by $9.0 million, of which $2.8 million related to the write-off in the second quarter of non-recoverable commissions related to the termination of the lease with Arthur Andersen LLP for

31


620,947 square feet at the Times Square Tower development project. The remaining increase related primarily to increases in compensation and related expenses, specifically an increase of $3.3 million to bonuses awarded to senior management for the year ended December 31, 2002 as compared to the year ended December 31, 2001, a $1.4 million increase related to a decrease in capitalized wages resulting from decreased development activity in 2002 compared to the year ended December 31, 2001, and a $0.5 million increase in costs incurred related to implementing the requirements of the Sarbanes-Oxley Act of 2002.

        In 2003, Boston Properties, Inc. transitioned to using solely restricted stock units, as opposed to stock options and restricted stock, awarded under the 1997 Stock Incentive Plan, as its primary vehicle for employee equity compensation. Employees vest in restricted stock unit awards over a five year term. Restricted stock and restricted stock units are measured at fair value on the date of grant based on the number of shares granted and the price of Boston Properties, Inc.'s common stock on the date of grant as quoted on the New York Stock Exchange. We recognize such value as an expense ratably over the corresponding employee service period. To the extent restricted stock or restricted stock units are forfeited prior to vesting, the corresponding previously recognized expense is reversed as an offset to "Stock-based compensation." Stock-based compensation associated with restricted stock units was $1.2 million during the year ended December 31, 2002. Stock-based compensation associated with approximately $6.1 million of restricted stock units which were granted in January 2003 will be incurred as such restricted stock units vest in years 2006 through 2008.

        Interest expense for the Total Portfolio increased as a result of having a higher average outstanding debt balance as compared to the prior period as well as decreased interest capitalization. This was primarily due to placing into service and cessation of interest capitalization on Five Times Square, 111 Huntington Avenue, and 611 Gateway and new debt incurred related to the acquisition of Citigroup Center and 399 Park Avenue. Our total debt outstanding at December 31, 2002 was approximately $5.1 billion, compared to $4.3 billion at December 31, 2001. This was partially offset by a decrease in our weighted average interest rates over the year from 6.57% at December 31, 2001 to 6.03% at December 31, 2002.

        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 year ended December 31, 2002 and 2001 were $5.1 million and $6.6 million, respectively. These costs are not included in the general and administrative expenses discussed above. Interest capitalized for the year ended December 31, 2002 and 2001 was $22.5 million and $59.3 million, respectively. These costs are not included in the interest expense referenced above.

        Depreciation and amortization expense for the Total Portfolio increased as a result of the additions of the Citigroup Center, Five Times Square, 111 Huntington Avenue and 399 Park Avenue properties and other properties that we acquired or placed in service after January 1, 2001. The increases were offset by decreases related to properties that were sold during 2002.

        Net derivative losses for the Total Portfolio represent the mark to market of our derivative contracts and payments that were not effective for accounting purposes. During the year ended December 31, 2002, we recognized a reduction in the fair value of our contracts as a result of generally low interest rates. The fair value of our derivative contracts is included on our balance sheet at December 31, 2002.

        During the year ended December 31, 2002, we recognized losses on our investments in securities of approximately $4.3 million. This loss was related to the write off of our investment in the securities of a technology company due to our determination that the decline in the fair value of these securities was an other than temporary decline.    The loss on investment of $6.5 million for the year ended

32


December 31, 2001 was related to the write off of investments in securities of two technology companies.

Joint Ventures

        Income from unconsolidated joint ventures for the Same Property Portfolio increased by $1.2 million for the year ended December 31, 2002. The primary result of the increase is related to the completion of the repositioning of 265 Franklin Street during 2001 as well as receiving preferential returns on certain other joint ventures resulting from the achievement of specified investment return thresholds. The additional increase in the total portfolio is related to the placing in service of One and Two Discovery Square.

Other

        Gains on sales of real estate for the year ended December 31, 2002 related to the sale of One and Two Independence Square were not included in discontinued operations, as we have continuing involvement through a third party management agreement.

        The decrease in income from discontinued operations for the year ended December 31, 2002 was a result of the properties classified as discontinued operations in accordance with SFAS 144 being sold prior to December 31, 2002, and therefore, we did not recognize a full year of revenues and expenses as we did in the prior year.

        Gains on sales of real estate from discontinued operations for the year ended December 31, 2002 related to the gain recognized on the properties that were sold. These properties included Fullerton Square, 2391 West Winton and 7600, 7700 and 7702 Boston Boulevard.

        The extraordinary item for the year ended December 31, 2002 related to a debt extinguishment charge we incurred in connection with the prepayment of debt in order in connection with the sale of our properties.

        The decrease in our preferred distributions from $36.0 million for the year ended December 31, 2001 to $31.3 million for the year ended December 31, 2002 was a result of the conversion of 3,567,518 shares of our preferred units into common units of BPLP, which common units, Boston Properties, Inc., as our general partner, elected to acquire in exchange for the same number of shares of its common stock.

Comparison of the year ended December 31, 2001 to the year ended December 31, 2000

        The table below shows selected operating information for the Same Property Portfolio and the Total Portfolio. The Same Property Portfolio consists of 115 properties, including three hotels and one property which we own a joint venture interest, acquired or placed in service on or prior to January 1, 2001 and owned by us through December 31, 2002. The Total Property Portfolio includes the effect of the other properties either placed in service or acquired after January 1, 2001 or disposed of on or prior to December 31, 2002. Our net property operating margins, which are defined as rental revenues less operating expenses exclusive of the three hotel properties for the year ended December 31, 2002, have ranged between 67% and 70%.

Revenue

        The increase in rental revenue in our Same Property Portfolio is primarily a result of an overall increase in rental rates on new leases and rollovers, an increase in reimbursable operating expenses as well as an increase in termination fees and early surrender income offset by a decrease in occupancy from year to year. Rental revenue is comprised of base rent, including termination fees, recoveries from tenants and parking and other. Base rental revenue is recognized on a straight-line basis over the terms of the respective leases. Accrued rental income represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with the lease agreements. Straight line rent for the year ended December 31, 2001 was $28.0 million compared to $13.1 million for the year ended December 31, 2000. Termination fees and early surrender income increased from $3.7 million for the year ended December 31, 2000 to $21.6 million for the year ended December 31, 2001. Included in the $21.6 million is $12.4 million related to the early surrender of space of a tenant at 875 Third Avenue, of which approximately $9.2 million has been received to date. We received the remaining amount on a monthly basis through July 2002. The occupancy for our Same Property Portfolio decreased from 98.9% as of December 31, 2000 to 95.8% as of December 31, 2001. Additional increases in rental revenues in our total portfolio are primarily the result of rental revenues earned on properties we acquired or placed in service after January 1, 2000 offset by a decrease in overall occupancy from 98.9% to 95.3%.

        The increase in development and management services income in our total portfolio is mainly due to income earned on contracts starting in 2001 and 2000 and an increase of approximately $0.4 million of work order profits earned on the entire portfolio. This was offset by certain management and development contracts ending in 2000 and some reductions in charges for management fees.

        The increase in interest and other income in our total portfolio is primarily due to more interest earned as a result of higher average cash balances in 2001 resulting from the remaining proceeds from an equity public offering by Boston Properties, Inc. of its common stock in October 2000, which proceeds were contributed to us, offset by lower interest rates.

Operating Expenses

        Property operating expenses (real estate taxes, utilities, repairs and maintenance, cleaning and other property-related expenses) in our Same Property Portfolio increased mainly due to increases in real estate taxes of $6.0 million, or 2.3%, and increases in utilities of $7.4 million, or 2.9%. Most office leases include reimbursement for these operating expenses. The increase in real estate taxes was primarily due to higher property tax assessments. Small increases in the other property operating expenses account for the remaining difference. Additional increases in property operating expenses in our total portfolio were due to properties we acquired or placed in service after January 1, 2000.

Hotel Net Operating Income

        Net operating income for the hotel properties decreased $2.4 million, or approximately 8.4%, for the year ended December 31, 2001 as compared to December 31, 2000. Average occupancy and REVPAR for the hotel properties were 80.5% and $158.5, respectively, for the year ended December 31, 2001 compared to 88.4% and $195.59, respectively, for the prior year. This was a result of a general downturn in the market as well as the events of September 11, 2001.

Other Expenses

        General and administrative expenses in our Total Portfolio increased mainly due to an overall increase in payroll due to an increase in the overall size of our Total Portfolio and the number of employees since January 1, 2000 as well as salary increases to employees. We wrote off $1.4 million of abandoned projects in 2001 compared to a $0.7 million write-off in 2000. In addition, the 2001 expense

34


does not include $3.0 million that was included in the prior year related to the departure of two senior employees.

        Interest expense for our Total Portfolio increased as a result of having a higher average outstanding debt balance as compared to the prior period. Our debt outstanding at December 31, 2001 was approximately $4.3 billion, compared to $3.4 billion at December 31, 2000. This was partially offset by a decrease in our weighted average interest rates over the year from 7.37% at December 31, 2000 to 6.57% at December 31, 2001.

        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 years ended December 31, 2001 and 2000 were $6.5 million and $5.1 million, respectively. These costs are not included in the general and administrative expenses discussed above. Interest capitalized for the years ended December 31, 2001 and 2000 was $59.3 million and $37.7 million, respectively. These costs are not included in the interest expense discussed above.

        Depreciation and amortization expense for our Same Property Portfolio increased as a result of capital and tenant improvements made during 2001. Additional increases in depreciation and amortization expense for our total portfolio were mainly due to the properties we acquired or placed in service after January 1, 2000 and related capital and tenant improvements.

        The net derivative losses incurred during 2001 result from the adoption of Financial Accounting Standard No. 133 ("FAS 133") "Accounting for Derivative Instruments and Hedging Activities" as well as the mark to market of the derivatives subsequent to adoption.

        The loss on investments in securities during 2001 resulted from the write down of investments in the securities of two publicly traded telecommunications companies. We determined that the decline in the fair value of these securities was other than temporary.

Joint Ventures

        Unconsolidated joint venture income increased as a result of income earned on joint venture properties being placed in service during 2001 and income earned on joint venture properties acquired after January 1, 2000.

Liquidity and Capital Resources

        The following summary discussion of our cash flows is based on the consolidated statements of cash flows in "Item 13. Financial Statements and Supplementary Data" and is not meant to be an all-inclusive discussion of the changes in our cash flows for the periods presented below.

        Cash and cash equivalents were $55.3 million and $98.1 million at December 31, 2002 and December 31, 2001, respectively. The decrease was a result of the following increases and decreases in cash flows:

Cash Provided by Financing Activities   $ 537,111   $ 701,329   $ (164,218 )

        Our principal source of cash flow is the operation of our office properties and proceeds from secured and unsecured borrowings. The average term of a tenant lease is approximately 7.2 years with occupancy rates historically in the range of 94% to 98%. Our properties provide a relatively consistent

35


stream of cash flow that provides us with resources to pay operating expenses, debt service and fund quarterly dividend and distribution payment requirements.

        Cash used in investing activities for year ended December 31, 2002 is primarily comprised of the following acquisitions and additions to real estate:

Represents our share of the total anticipated project-level investment and construction loan.

        In total, our existing construction loans on the above projects have $371.7 million remaining to be drawn out of a total of $702.5 million. Of our remaining commitment of $405.9 million to complete these developments, $368.7 million will be covered under our existing construction loans and $34.2 million from existing cash or draws from our unsecured line of credit.

        Cash is used in investing activities to fund acquisitions, development and recurring and nonrecurring capital expenditures. The office of the Executive Vice President for Operations for Boston Properties, Inc. establishes the annual budget for capital improvement projects in consultation with regional management. All new projects require the Executive Vice President for Operations for Boston Properties, Inc. or his designee to approve the capital budget before commencement of work. We selectively invest in new projects which enable us to take advantage of our development skills and invest in existing buildings which meet our stringent investment criteria, with the objective of becoming a dominant landlord in our markets. In September 2002, we purchased 399 Park Avenue which we believe is one of New York City's premier properties. The ability to acquire a property of this caliber is a testament to our competitive advantage of meeting a seller's tight schedule for performing due

36


diligence, negotiating agreements, financing and closing within a month's timeframe. In connection with this acquisition of and as a source of permanent financing for 399 Park Avenue, we executed on a disciplined strategy of re-deploying capital through the sale of some of our premier properties to harvest embedded value.

        Cash provided by financing activities decreased $164.2 million for the year ended December 31, 2002. This was due to changes in our existing debt structure, including the paydown of certain construction loans and amounts outstanding on our unsecured revolving line of credit and our unsecured bridge loan. This was offset by our issuance of $750 million of unsecured senior notes. Future debt payments are discussed below under the heading "Debt Financing."

        We draw on multiple financing sources to fund our 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 new development with construction loans which may be partially guaranteed by BPLP until project completion or lease-up thresholds are achieved. In December 2002, we completed a highly successful initial offering of unsecured investment grade senior notes and have made a commitment to utilize the bond market as a cost-effective financing source, in addition to asset backed mortgage financing and common and preferred equity.

Capitalization

        At December 31, 2002, our total consolidated debt was approximately $5.1 billion. The weighted-average annual interest rate on our consolidated indebtedness was 6.03% and the weighted average maturity was approximately 5.4 years.

        Our total market capitalization was approximately $9.8 billion at December 31, 2002. Total market-capitalization is the sum of our total indebtedness outstanding on a consolidated basis (excluding unconsolidated joint venture debt) and the market value of our outstanding equity securities. Our market value was calculated using the December 31, 2002 Boston Properties, Inc. closing stock price of $36.86 per share multiplied by the sum of (i) the actual aggregate number of outstanding common units of BPLP (including common units held by Boston Properties, Inc.) and (ii) the number of common units issuable upon conversion of the Series One and Series Two preferred units of BPLP. Our total outstanding indebtedness, on a consolidated basis, at December 31, 2002 represented approximately 52.8% of our total market capitalization.

        On July 9, 2002, we converted certain of our Series Two and all of our Series Three preferred units of limited partnership interest, as well as all of the Series A Parallel preferred units of limited partnership interest underlying the shares of Boston Properties, Inc.'s Series A Convertible preferred stock, into common units of limited partnership interests. The preferred securities so converted had an aggregate liquidation preference of approximately $140.6 million.

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

        We utilize our $605.0 million unsecured revolving line of credit principally to fund development of properties, land and property acquisitions, and for working capital purposes. Our unsecured revolving line of credit is a recourse obligation. Based on terms of the extension discussed below, outstanding balances under the unsecured revolving line of credit bear interest at a floating rate based on an increase over the Eurodollar rate of 70 basis points (145 basis points at December 31, 2002) or the lender's prime rate, at our option. The interest rate is subject to adjustment in the event of a change in our unsecured debt ratings.

        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: (1) 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%, (2) a secured debt leverage ratio not to exceed 55%, (3) a debt service coverage ratio of 1.40 for our borrowing base, (4) a fixed charge ratio of 1.30 and a debt service coverage ratio of 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. If we fail to comply with our financial and other covenants in our revolving line of credit, our lender could place us in default and accelerate the payment of any amounts then outstanding. As of December 31, 2002, we were in compliance with financial restrictions and requirements then applicable.

        At December 31, 2002, we had letters of credit totaling $1.9 million outstanding under our unsecured line of credit and an outstanding draw of $146.9 million secured by our property at 875

38


Third Avenue, and had the ability to borrow an additional $429.2 million under our unsecured revolving line of credit which had a maturity date of March 31, 2003. In January 2003, we extended the maturity date to January 17, 2006 with an additional one-year extension option. The covenants discussed above are those required under our extension agreement. As of February 19, 2003, we had $572.1 million available under our unsecured revolving line of credit.

        During the year ended December 31, 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 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%. At December 31, 2002, there was $747.4 million aggregated principal amount of the notes outstanding (net of unamortized discount of $2.6 million).

        On January 17, 2003, we completed an unregistered offering to qualified institutional investors 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.

        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 December 31, 2002, we were in compliance with each of these financial restrictions and requirements.

        Under a registration rights agreement with the initial purchasers of our senior unsecured notes, we agreed to use our reasonable best efforts to register with the SEC an offer to exchange new notes issued by us, which we refer to as "exchange notes," for the original notes. The exchange notes will be in the same aggregate principal amount as, and have terms substantially identical to the original notes, but will be freely tradable by the holders, while the original notes are subject to resale restrictions. The exchange offer will not generate any cash proceeds for us. If we are unable to file the exchange offer registration statement by March 10, 2003 or to complete the registered exchange offer by July 7, 2003, we will be obligated to pay additional interest on the notes until the exchange offer is completed or a so-called "shelf" registration statement covering the resale of the original notes by their holders is declared effective. We currently expect to meet these deadlines.

        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.

        As of December 31, 2002, our total mortgage notes (excluding our share of unconsolidated joint venture debt described below) consisted of approximately $3.1 billion of fixed rate debt and $1.1 billion of variable rate debt with weighted average interest rates of 6.99% and 3.07% respectively.

        LIBOR and Eurodollar rate contracts in effect on December 31, 2002 ranged from LIBOR/Eurodollar + 1.25% to LIBOR/Eurodollar + 1.95%.

        Our mortgage notes payable at December 31, 2002 will mature as follows:

2004     411,855
2005     285,387

        Of the $931.5 million payable during 2003, we have repaid $425.8 during January and February of 2003 with proceeds from our offerings of unregistered senior notes as well as proceeds from sales of properties. In addition, we have extended the maturity date on the 5 Times Square construction loan which had $372.9 million outstanding at December 31, 2002 to December 31, 2004. Of the remaining $132.8 million due in 2003, we expect to fund the payments through cash flows from operations, proceeds from unsecured debt transactions and drawdowns from our revolving unsecured line of credit.

General

        We have determined that our estimated cash flows and available sources of liquidity are adequate to meet liquidity needs for the next twelve months. We believe that our principal liquidity needs for the next twelve months are to fund normal recurring expenses, debt service requirements, current development costs not covered under construction loans and the minimum distribution required to maintain the REIT qualification of Boston Properties, Inc. under the Internal Revenue Code of 1986, as amended. We believe that these needs will be fully funded from cash flows provided by operating and financing activities.

42

        We expect to meet liquidity requirements for periods beyond twelve months for the costs of development, property acquisitions, scheduled debt maturities, major renovations, ground lease payments, expansions and other non-recurring capital improvements through construction loans, the incurrence of long-term secured and unsecured indebtedness, income from operations and sales of real estate and possibly the issuance of additional common and preferred units and our unsecured senior notes and equity securities of Boston Properties, Inc., the proceeds of which will then be contributed to us. In addition, we may finance the development, redevelopment or acquisition of additional properties by using our unsecured revolving line of credit.

        Rental revenues, operating expense reimbursement income from tenants, and other income from operations are our principal sources of capital used to pay operating expenses, debt service and recurring capital expenditures. We seek to increase income from our existing properties by maintaining quality standards for our properties that promote high occupancy rates and permit increases in rental rates while reducing tenant turnover and controlling operating expenses. Our sources of revenue also include third party fees generated by our office and industrial 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 operating expenses, debt service and recurring capital expenditures. 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, capital improvements and non-revenue enhancing tenant improvements. In addition, a material adverse change in our cash provided by operations may affect the financial performance covenants under our unsecured line of credit and unsecured senior notes.

        Based on leases in place at December 31, 2002, leases with respect to 4.4% of our Class A office buildings will expire in calendar year 2003. Although we are unable to estimate the actual rate of future leases, we believe that the short term expiring leases may be renewed, or space re-let, at lower or the same rents than previously in effect. While we are working to retain our current tenants in situations that are beneficial to us, conditions over the past year, including more sublet space available and decreasing rental rates across the board, make it difficult for us to predict what future changes may be and how they will effect our re-leasing efforts.

        During the year ended December 31, 2002, we made distributions totaling $2.41 per common unit (consisting of $.58 per unit related to the quarter ended March 31, 2002 and $.61 per unit related to each of the quarters ended June 30, 2002, September 30, 2002 and December 31, 2002). We intend to continue making distributions quarterly.

Market Risk

        Market risk is the risk of loss from adverse changes in market prices and interest rates. Our future earnings, cash flows and fair values relevant to financial instruments are dependent upon prevalent market interest rates, including refinancing risk on our fixed rate debt. Our primary market risk results from our indebtedness, which bears interest at fixed and variable rates. The fair value of our long-term debt obligation is affected by changes in the market interest rates. We manage our market risk, in part, by attempting to match our long-term leases with long-term fixed rate debt of similar duration. We also utilize certain derivative financial instruments at times to further reduce interest rate risk. Although certain derivative instruments were not effective for accounting purposes, derivatives have been used to convert a portion of our variable rate debt to a fixed rate, or to hedge anticipated financing transactions. Derivatives are used solely for risk management purposes rather than speculation. Approximately 75% of our outstanding debt has fixed interest rates, which minimizes the interest rate risk until the maturity of such outstanding debt.

        At December 31, 2002, we had derivative contracts totaling $150 million. The derivative agreements provide 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 9.0% for terms

43

remaining from one to three years per the individual agreement. We will consider entering into additional derivative agreements with respect to all or a portion of our debt. We may borrow additional money with variable rates in the future. Increases in interest rates could increase interest expense, which in turn could affect cash flow and our ability to service our debt. As a result of the derivative contracts, decreases in interest rates could increase interest expense as compared to the underlying variable rate debt and could result in us making substantial payments to unwind such agreements.

        During the year ended December 31, 2002, in anticipation of issuing fixed rate debt instruments, we entered into treasury lock agreements to hedge against a potential increase in the ten-year treasury rate. Upon the issuance of the fixed rate debt, we paid approximately $3.5 million to terminate the instrument, which amount is being amortized into interest expense over the term of the unsecured senior notes.

        At December 31, 2002, our variable rate debt outstanding was approximately $1.3 billion. At December 31, 2002, the average interest rate on variable rate debt was approximately 3.04%. Exclusive of our derivative contracts, if market interest rates on our variable rate debt were to increase by 100 basis points, total interest would have increased approximately $12.6 million for the year ended December 31, 2002.

        At December 31, 2001, our variable rate debt outstanding was approximately $866.0 million. At December 31, 2001, the average interest rate on variable rate debt was approximately 3.77%. Exclusive of our derivative contracts, if market interest rates on our variable rate debt were to increase by 100 basis points, total interest would have increased approximately $8.7 million for the year ended December 31, 2001.

        These amounts were determined solely by considering the impact of hypothetical interest rates on our financial instruments and not including the effects of our derivative contracts. Due to the uncertainty of specific actions we may undertake to minimize possible effects of market interest rate increases, this analysis assumes no changes in our financial structure.

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 accounting principles generally accepted in the United States of America ("GAAP"), including non-recurring items), for gains (or losses) from sales of properties, real estate related depreciation and amortization, and after adjustment for unconsolidated partnerships and joint ventures. In addition to FFO (as defined by NAREIT), we also disclose FFO after specific supplemental adjustments. Although our FFO as adjusted clearly differs from NAREIT's definition of FFO as well that of other real estate companies, we believe it provides a meaningful presentation of our operating performance. In addition, we believe that to further understand our performance, FFO and FFO as adjusted should be compared with our reported net income and cash flows in accordance with GAAP, as presented in our consolidated financial statements.

        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 make adjustments to FFO, as defined by NAREIT, including net derivative losses and early surrender lease adjustments. FFO does not represent cash generated from operating activities determined in accordance with GAAP, and should not be considered as an alternative to net income (determined in accordance with GAAP) as an indication of our performance, as an alternative to net cash flows from operating activities (determined in accordance with GAAP), as a measure of our liquidity, or as an indicator of our ability to make cash distributions.

Off Balance Sheet Arrangements

Joint Ventures

        We have investments in eight unconsolidated joint ventures with ownership interests ranging from 25% to 51%. We do not have control of these partnerships, and therefore, they are presently accounted for using the equity method of accounting. At December 31, 2002, our share of the debt related to these investments was equal to approximately $236.8 million. The table below summarizes the outstanding debt (based on our respective ownership interests) in these joint venture properties at December 31, 2002:

Under construction at December 31, 2002.

        We will have $49.8 million of principal expiring during 2003. We expect to utilize our extension options under both construction loans.

        In connection with the development of office properties, we and/or our equity affiliates have agreed to fund the remaining equity capital associated with approved development projects of joint ventures aggregating approximately $143.4 million (of which our share is $40.9 million). These obligations are expected to be financed through new or existing construction loans plus approximately $3.4 million of our equity investment.

Environmental Matters

        It is our policy to retain independent environmental consultants to conduct or update Phase I environmental assessments (which generally do not involve invasive techniques such as soil or ground water sampling) and asbestos surveys with respect to our properties. These pre-purchase environmental assessments have not revealed environmental conditions that we believe will have a material adverse effect on our business, assets or results of operations, and we are not otherwise aware of environmental conditions with respect to our properties which we believe would have such a material adverse effect. However, from time to time pre-existing environmental conditions at our properties have required environmental testing and/or regulatory filings.

        In February 1999, one of our affiliates acquired from Exxon Corporation a property in Massachusetts that was formerly used as a petroleum bulk storage and distribution facility and was known by the state regulatory authority to contain soil and groundwater contamination. We recently completed development of an office park on the property. Our affiliate engaged a specially licensed environmental consultant to oversee the management of contaminated soil and groundwater that was disturbed in the course of construction. Pursuant to the property acquisition agreement, Exxon agreed

47

to (1) bear the liability arising from releases or discharges of oil and hazardous substances which occurred at the site prior to our ownership, (2) continue remediating such releases and discharges as necessary and appropriate to comply with applicable requirements, and (3) indemnify our affiliate for certain losses arising from preexisting site conditions. Any indemnity claim may be subject to various defenses.

        Environmental investigations at two of our properties in Massachusetts have identified groundwater contamination migrating from off-site source properties. In both cases we engaged a specially licensed environmental consultant to perform the necessary investigations and assessments and to prepare submittals to the state regulatory authority, including Downgradient Property Status Opinions. The environmental consultant concluded that the properties qualify for Downgradient Property Status under the state regulatory program, which eliminates certain deadlines for conducting response actions at a site. We also believe that these properties qualify for liability relief under certain statutory amendments regarding upgradient releases. Although we believe that the current or former owners of the upgradient source properties may ultimately be responsible for some or all of the costs of addressing the identified groundwater contamination, we will take necessary further response actions (if any are required). No such additional response actions are anticipated at this time.

        One of our affiliates recently acquired a property in Massachusetts where historic groundwater contamination was identified prior to acquisition. We engaged a specially licensed environmental consultant to perform investigations and to prepare necessary submittals to the state regulatory authority. The environmental consultant has concluded that (1) certain identified groundwater contaminants are migrating to the subject property from an off-site source property and (2) certain other detected contaminants are likely related to a historic release on the subject property. We have filed a Downgradient Property Status Opinion (described above) with respect to contamination migrating from off-site. The consultant has recommended conducting additional investigations, including the installation of off-site monitoring wells, to determine the nature and extent of contamination potentially associated with the historic use of the subject property. Our affiliate has authorized such additional investigations and will take necessary further response actions (if any are required).

        Some of our properties and certain properties owned by our affiliates are located in urban, industrial and other previously developed areas where fill or current or historical uses of the areas have caused site contamination. Accordingly, it is sometimes necessary to institute special soil and/or groundwater handling procedures in connection with construction and other property operations in order to achieve regulatory closure and ensure that contaminated materials are addressed in an appropriate manner. In these situations it is our practice to investigate the nature and extent of detected contamination and estimate the costs of required response actions and special handling procedures. We then use this information as part of our decision-making process with respect to the acquisition and/or development of the property. For example, we recently acquired a parcel in Massachusetts, formerly used as a quarry/asphalt batching facility, which we may develop in the future. Pre-purchase testing indicated that the site contains relatively low levels of certain contaminants. We have engaged a specially licensed environmental consultant to perform an environmental risk characterization and prepare all necessary regulatory submittals. We anticipate that additional response actions necessary to achieve regulatory closure (if any) will be performed in concert with future construction activities. When appropriate, closure documentation will be submitted for public review and comment pursuant to the state regulatory authority's public information process.

        We expect that resolution of the environmental matters relating to the above will not have a material impact on our financial position, results of operations or liquidity.

Newly Issued Accounting Standards

        In June 2001, the FASB issued SFAS 141, "Business Combinations," and SFAS 142, "Goodwill and Other Intangible Assets." The provisions of SFAS 141 apply to all business combinations initiated after June 30, 2001. SFAS 142 becomes effective beginning January 1, 2002. We adopted both these pronouncements for the year ended December 31, 2002 and neither had a material impact on our results of operations, financial position or liquidity.

        In August 2001, the FASB issued SFAS 143, "Accounting for Asset Retirement Obligations." SFAS 143 requires an entity to record a liability for an obligation associated with the retirement of an asset at the time the liability is incurred by capitalizing the cost as part of the carrying value of the related asset and depreciating it over the remaining useful life of that asset. The standard is effective beginning January 1, 2003. The changes required by SFAS 143 are not expected to have a material impact on our results of operations, financial position or liquidity.

        SFAS 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," was issued in October 2001 and addresses how and when to measure impairment on long-lived assets and how to account for long-lived assets that an entity plans to dispose of either through sale, abandonment, exchange, or distribution to owners. The statement's provisions supersede SFAS 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," which addressed asset impairment, and certain provisions of APB Opinion 30 related to reporting the effects of the disposal of a business segment and requires expected future operating losses from discontinued operations to be recorded in the period in which the losses are incurred rather than the measurement date. Under SFAS 144, more dispositions may qualify for discontinued operations treatment in the income statement. The provisions of SFAS 144 became effective on January 1, 2002, and did not have a material impact on results of operations, financial position, or liquidity.

        In April 2002, the FASB issued SFAS 145, which updates, clarifies, and simplifies certain existing accounting pronouncements beginning at various dates in 2002 and 2003. The statement rescinds SFAS 4 and SFAS 64, which required net gains or losses from the extinguishment of debt to be classified as an extraordinary item in the income statement. We anticipate that these gains and losses will no longer be classified as extraordinary as they are not unusual and infrequent in nature. The changes required by SFAS 145 are not expected to have a material impact on our results of operations, financial position, or liquidity.

        SFAS 146, "Accounting for Costs Associated with Exit or Disposal Activities," was issued in July 2002 and becomes effective for us beginning January 1, 2003. This statement requires a cost associated with an exit or disposal activity, such as the sale or termination of a line of business, the closure of business activities in a particular location, or a change in management structure, to be recorded as a liability at fair value when it becomes probable the cost will be incurred and no future economic benefit will be gained by the company for such termination costs, and costs to consolidate facilities or relocate employees. SFAS 146 supersedes EITF Issue No. 94-3, "Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity," which in some cases required certain costs to be recognized before a liability was actually incurred. The adoption of this standard is not expected to have a material impact on our results of operations, financial position, or liquidity.

        In December 2002, the FASB issued SFAS 148, "Accounting for Stock-Based Compensation—Transition and Disclosure," which provides guidance on how to transition from the intrinsic value method of accounting for stock-based employee compensation under APB 25 to SFAS 123's fair value method of accounting, if a company so elects. The adoption of this standard is not expected to have a material impact on our results of operations, financial position or liquidity.

        In November 2002, the FASB issued FASB Interpretation No. 45 (FIN 45), "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of

49

Indebtedness of Others." This interpretation expands the disclosures to be made by a guarantor in its financial statements about its obligations under certain guarantees and requires the guarantor to recognize a liability for the fair value of an obligation assumed under a guarantee. FIN 45 clarifies the requirements of SFAS 5, Accounting for Contingencies, relating to guarantees. In general, FIN 45 applies to contracts or indemnification agreements that contingently require the guarantor to make payments to the guaranteed party based on changes in an underlying that is related to an asset, liability, or equity security of the guaranteed party. The disclosure requirements of FIN 45 are effective to us as of December 31, 2002, and require disclosure of the nature of the guarantee, the maximum potential amount of future payments that the guarantor could be required to make under the guarantee, and the current amount of the liability, if any, for the guarantor's obligations under the guarantee. The recognition requirements of FIN 45 are to be applied prospectively to guarantees issued or modified after December 31, 2002. We do not expect the requirements of FIN 45 to have a material impact on results of operations, financial position, or liquidity.

        In January 2003, the FASB issued FASB Interpretation No. 46 (FIN 46), "Consolidation of Variable Interest Entities." The objective of this interpretation is to provide guidance on how to identify a variable interest entity ("VIE") and determine when the assets, liabilities, noncontrolling interests, and results of operations of a VIE need to be included in a company's consolidated financial statements. A company that holds variable interests in an entity will need to consolidate the entity if the company's interest in the VIE is such that the company will absorb a majority of the VIE's expected losses and/or receive a majority of the entity's expected residual returns, if they occur. FIN 46 also requires additional disclosures by primary beneficiaries and other significant variable interest holders. The provisions of this interpretation became effective upon issuance. We do not believe the adoption of the interpretation will have a material impact on results of operations, financial position, or liquidity.

Inflation

        Substantially all of our leases provide for separate real estate tax and operating expense escalations over a base amount. In addition, many of our leases provide for fixed base rent increases or indexed increases. We believe that inflationary increases may be at least partially offset by the contractual rent increases described above.

An option is "in-the-money" if the fair market value of the shares of common stock underlying the option exceeds the option exercise price.

EMPLOYMENT AND NONCOMPETITION AGREEMENTS

        Mr. Mortimer B. Zuckerman, as Chairman of the Board of Directors of Boston Properties, Inc., and Mr. Edward H. Linde, as President and Chief Executive Officer of Boston Properties, Inc., each has an employment and noncompetition agreement with Boston Properties, Inc. Pursuant to each agreement, during the term of such agreement, Mr. Zuckerman will devote a majority of his business time, and Mr. Linde will devote substantially all of his business time, to Boston Properties, Inc.'s business and affairs. The initial term of each agreement is three years beginning on January 17, 2003, in the case of Mr. Zuckerman, and November 29, 2002, in the case of Mr. Linde, with automatic one-year renewals commencing on each anniversary date unless written notice of termination is given 90 days prior to such date by either party. Apart from base salaries, each of Messrs. Zuckerman and Linde is eligible to receive bonus compensation, including stock options and restricted stock, to be determined in the discretion of the Compensation Committee of the Board of Directors of Boston Properties, Inc.. Each of Messrs. Zuckerman's and Linde's employment with Boston Properties, Inc. may be terminated for "cause" by Boston Properties, Inc. for (1) gross negligence or willful misconduct, (2) an uncured breach of any of his material duties under the employment agreement, (3) fraud or other conduct against Boston Properties, Inc.'s material best interests, or (4) an indictment of a felony if such indictment has a material adverse effect on Boston Properties, Inc. Each of Messrs. Zuckerman and Linde may terminate his employment for "good reason," which includes (1) a substantial adverse change in the nature or scope of his responsibilities and authority under his employment agreement, (2) an uncured breach by Boston Properties, Inc. of any of its material obligations under his employment agreement or (3) an involuntary relocation of the office at which the employee is principally employed to a location more than 50 miles from such office, or the requirement that the employee be based at another office on an extended basis. If the employment of either of Messrs. Zuckerman or Linde is terminated by Boston Properties, Inc. "without cause" or by either of Messrs. Zuckerman or Linde for "good reason," then the respective employee will be entitled to a severance amount payable over a 12-month period equal to the sum of (x) his base salary plus (y) the amount of his cash bonus received in respect of the immediately preceding year. Each of Messrs. Zuckerman and Linde is also entitled to an additional 12 months of vesting in his stock-based awards and, subject to payment of premiums, may also participate in our health plan for up to 12 months.

        The employment agreements prohibit each of Messrs. Zuckerman and Linde, while he is director or officer of Boston Properties, Inc. and for one year thereafter, from (1) engaging, directly or indirectly, in the acquisition, development, construction, operation, management, or leasing of any commercial real estate property, (2) intentionally interfering with Boston Properties, Inc.'s relationships with its tenants, suppliers, contractors, lenders or employees or with any governmental agency, or (3) soliciting its tenants or employees. Pursuant to each employment agreement, however, Messrs. Zuckerman and Linde may engage in minority interest passive investments which include the acquisition, holding, and exercise of voting rights associated with investments made through (1) the purchase of securities that represent a non-controlling, minority interest in an entity or (2) the lending of money, but without management of the property or business to which such investment directly or indirectly relates and without any business or strategic consultation with such entity. In addition, each of Messrs. Zuckerman and Linde may participate as an officer or director of any organization that is not engaged in real estate activities provided that such activities do not materially restrict the individual's ability to fulfill his obligation to Boston Properties, Inc. as an employee or officer. In addition, each employment agreement provides that the noncompetition provision shall not apply if Messrs. Zuckerman's or Linde's employment is terminated following a change of control of Boston Properties, Inc.

        Messrs. Burke, Koop, M. Landis, Douglas T. Linde, Norville, Pester, Ritchey and Selsam have employment agreements with Boston Properties, Inc. similar to that of Mr. Linde, except that the initial

77


term of the employment agreements is two years instead of three years, and these employees are permitted to participate as an officer or director of charitable organizations only. Additionally, the geographic scope of the noncompetition provisions contained in the employment agreements is limited to Boston Properties, Inc.'s markets at the time of termination of their employment. In the case of Mr. Pester's agreement, in order to comply with California law that generally prohibits restrictive covenants in employment agreements, the noncompetition provision is limited to non-solicitation of employees and non-interference of business relationships.

        Boston Properties, Inc. will continue to be subject during the term of Mr. Selsam's employment to an agreement dated August 10, 1995 pursuant to which (1) he is eligible to receive commissions of 33.33% of any leasing commission received by Boston Properties, Inc. in connection with the lease of 90 Church Street, New York, New York and (2) he is paid 5% of the management fees earned on the same property. Mr. Selsam did not receive any commissions, but did receive $17,763 in management fees for fiscal year 2002.

SEVERANCE AGREEMENTS

        Boston Properties, Inc. entered into severance agreements with each of Mr. Zuckerman and Mr. Edward H. Linde on July 30, 1998. The severance agreements provide for severance benefits to Mr. Zuckerman and Mr. Linde in the event of their termination under certain circumstances within 24 months following a "change in control." In the event a "terminating event" occurs within 24 months following a "change in control," Mr. Zuckerman and Mr. Linde will each receive a lump sum amount equal to $3,000,000 if the date of termination is in the year 1998, $3,300,000 if the date of termination is in the year 1999, and $3,630,000 if the date of termination is in year 2000 or later. Health, dental and life insurance benefits are provided for three (3) years following termination. Finally, the severance agreements provide for tax protection in the form of excise tax gross-up as well as financial counseling, tax preparation assistance and outplacement counseling.

        Boston Properties, Inc. adopted the Boston Properties, Inc. Senior Executive Severance Plan (referred to as the senior plan) in order to reinforce and encourage the continued attention and dedication of the Executive Vice Presidents, the Chief Financial Officer and the Regional Office Heads. The senior plan provides for the payment of severance benefits to each such executive officer in the event of termination under certain circumstances within 24 months following a "change in control" of up to three (3) times such executive officers' annual base salary and three (3) times the amount of the average annual bonus earned by the executive officer with respect to the three (3) calendar years immediately prior to the "change in control." Tax protection, financial counseling, tax preparation assistance, outplacement counseling and continuation of health, dental and life insurance is the same as described above in the severance agreements.

        Boston Properties, Inc. adopted the Boston Properties, Inc. Executive Severance Plan (referred to as the executive plan) in order to reinforce and encourage the continued attention and dedication of the Senior Vice Presidents and those Vice Presidents with ten (10) or more years of tenure with Boston Properties, Inc. The executive plan is the same as the senior plan except that each such senior officer will receive a payment of up to two (2) times such senior officers annual base salary and two (2) times the amount of the average annual bonus. Financial counseling, tax preparation assistance, outplacement counseling and continuation of health, dental and life insurance benefits is provided for two (2) years following termination.

Compensation Committee Interlocks and Insider Participation

        Boston Properties, Inc. has established a Compensation Committee consisting of Messrs. Seidenberg, Patricof and Salomon. None of them has served as an officer or employee of Boston Properties, Inc. or has any other business relationship or affiliation with Boston Properties, Inc.,

78


except his service as a director. None of these persons had any relationships with Boston Properties, Inc. requiring disclosure under applicable rules and regulations.


Item 7.    Certain Relationships and Related Transactions

Transactions with Management and Others

        Mr. Turchin, a director of Boston Properties, Inc., is a non-executive/non-director Vice Chairman of Insignia. Through an arrangement with Insignia that has been in place since 1985, Turchin & Associates, an affiliate of Mr. Turchin, participates in brokerage activities for which Insignia is retained as leasing agent, some of which involve leases for space within buildings owned by us. During the period from the date Mr. Turchin became a member of the Board of Directors of Boston Properties, Inc. in 1997 through December 31, 2002, Turchin & Associates has advised us that it has received $2.3 million from Insignia attributable to properties owned by us. Of this amount, $0.7 million (or approximately 30%) is in conjunction with funds we owed to Insignia related to the acquisition of 280 Park Avenue. The total amount that was paid to Turchin & Associates, excluding amounts paid related to obligations assumed in connection with the acquisition of 280 Park Avenue, represents approximately 4.83% of the total amount paid to Insignia by us since the date Mr. Turchin became a director of Boston Properties, Inc. in 1997. Pursuant to its arrangement with Insignia, Turchin & Associates has confirmed to us that it is paid on the same basis with respect to properties owned by us as it is with respect to properties owned by other clients of Insignia. Mr. Turchin does not participate in any discussions or other activities relating to our contractual arrangements with Insignia either in his capacity as a member of the Board of Directors of Boston Properties, Inc. or as a Vice Chairman of Insignia.

Certain Business Relationships

        We are managed by Boston Properties, Inc., in its capacity as our general partner. The transactions described below relate to transactions with directors, executive officers, or any stockholder known to own of record or beneficially more than 5% of the outstanding shares of common stock of Boston Properties, Inc.

        We paid Applied Printing Technologies, a printing company affiliated with Mr. Mortimer B. Zuckerman, approximately $80,000 for printing services provided in 2002, principally relating to the printing of Boston Properties, Inc.'s annual report to stockholders. The selection of Applied Printing Technologies as the printer for the Boston Properties, Inc. annual report to stockholders was made through a bidding process open to multiple printing companies.

        A joint venture in which we have a 50% interest, paid aggregate leasing commissions in 2002 of approximately $600,000 to a firm controlled by Mr. Raymond A. Ritchey's brother. Mr. Ritchey is an Executive Vice President of Boston Properties, Inc. The terms of the related agreement are at least as favorable to us as arrangements with other brokers in comparable markets.


Item 8.    Legal Proceedings

        Neither we, nor our affiliates, are presently subject to any material litigation or, to our knowledge, have any litigation threatened against us or our affiliates other than routine actions and administrative

79


proceedings substantially all of which are expected to be covered by liability or other insurance and in the aggregate are not expected to have a material adverse effect on our business or financial condition.


Item 9.    Market Price and Distributions and Related Security Holder Matters

        There is no established trading market for the common units of limited partnership interest. As of December 31, 2002, there were 207 holders of record of common units of limited partnership interest including Boston Properties, Inc.

        The following table sets forth the quarterly distributions per common unit of limited partnership interest declared by BPLP with respect to each such period.

Paid on January 29, 2003 to holders of record on December 30, 2002.

        We currently intend to continue to make regular quarterly distributions to holders of our common units. Any future distributions will be declared at the discretion of the board of directors of Boston Properties, Inc., our general partner, and will depend on actual cash flow of BPLP, its financial condition, capital requirements, the annual distribution requirements under the REIT provisions of the Internal Revenue Code of 1986, as amended, and such other factors as the board of directors may deem relevant.

        At the present time, (i) there are no common units subject to outstanding options or warrants to purchase; (ii) there are 2,376,853 Series One preferred units which are currently convertible into 2,112,760.86 common units and 5,400,661.53 Series Two preferred units which are convertible into 7,087,482.55 common units; (iii) there are 29,674,484.78 common units which could be sold pursuant to Rule 144 under the Securities Act of 1933, as amended (the "Securities Act"), subject to other restrictions on transfer in the securities laws or in our partnership agreement; and (iv) there are no common units that have been, or are proposed to be publicly offered by BPLP. Generally common units may be transferred without the consent and approval of Boston Properties, Inc., as our general partner, subject to certain limitations. See "Description of Securities to be Registered—Transferability of Interests." Although we have not entered into any agreements to register the common units under the Securities Act, Boston Properties, Inc., as our general partner, has agreed to register 29,647,663.78 shares of common stock, which are issuable upon redemption of the common units.


Item 10.    Recent Sales of Unregistered Securities

        On December 13, 2002, we issued $750 million of our 6.25% unsecured senior notes due January 15, 2013. The notes were priced at 99.65% of their face amount to yield 6.296% (the "December Notes"). The December Notes were sold to qualified institutional investors in the United States under Rule 144A under the Securities Act and to certain institutional investors outside of the United States under Regulation S under the Securities Act. On January 17, 2003 we re-opened the series and issued an additional $175 million aggregate principal amount of 6.25% unsecured senior notes due January 15, 2013 (the "January Notes"). The January Notes were priced at 99.76% of their

80


face amount to yield 6.28%. The January Notes were sold to qualified institutional buyers in the United States under Rule 144A. The January Notes are fungible, and form one series, with the December Notes. In connection with both of the offerings, we agreed, subject to certain terms and conditions, to register an exchange offer in which the outstanding unregistered notes will be exchanged for registered notes of identical principal amount and with substantially identical terms.

        During the past three years, we have issued units of limited partnership interest in private placements in reliance on the exemption from registration under Section 4(2) of the Securities Act of 1933 in the amounts and for the consideration set forth below:

81


Item 11.    Description of Securities to be Registered

General

        The following description is only a summary of certain provisions of the limited partnership agreement of BPLP and is subject to, and qualified in its entirety by, the partnership agreement, a copy of which has been filed with the Securities and Exchange Commission.

Voting Rights

        Under our partnership agreement, our limited partners do not have voting rights relating to the operation and management of BPLP, except in connection with matters, as described more fully below, involving amendments to our partnership agreement, dissolution of BPLP and the sale or exchange of all or substantially all of our assets, including mergers or other combinations. Holders of all classes of preferred units have the right to a separate class vote on any matter that would materially and adversely effect any right, preference, privilege or voting power of the preferred units or their holders.

82

Vote Required to Dissolve Boston Properties Limited Partnership

        Under our partnership agreement and Delaware law, BPLP may be dissolved only upon an election to dissolve by Boston Properties, Inc., as general partner, and the affirmative consent of limited partners (including Boston Properties, Inc.) holding 85% of the units of limited partnership interest.

Vote Required to Sell Assets or Merge

        Boston Properties, Inc., as general partner, has agreed in our partnership agreement not to engage in business combinations unless the limited partners of BPLP other than Boston Properties, Inc. who hold the remaining common units receive, or have the opportunity to receive, the same consideration for their partnership interests as holders of common stock of Boston Properties, Inc. in the transaction. If these limited partners do not receive the same consideration, Boston Properties, Inc. cannot engage in the transaction unless 75% of these holders of common units vote to approve the transaction. In addition, Boston Properties, Inc. has agreed in our partnership agreement that it will not consummate business combinations in which it received the approval of the stockholders of Boston Properties, Inc. unless holders of common units are also allowed to vote and the transaction would have been approved had these holders of common units been able to vote as stockholders on the transaction. Therefore, if the stockholders of Boston Properties, Inc. approve a business combination that requires a vote of stockholders, our partnership agreement requires the following before we can consummate the transaction:

Meetings of the Partners

        Meetings of the partners may be called by the general partner and must be called by the general partner upon receipt of a written request by limited partners holding 20% or more of the partnership interests. The notice must state the nature of the business to be transacted, and must be given to all partners not less than seven (7) days nor more than thirty (30) days prior to the date of such meeting. Partners may vote in person or by proxy at such meeting. Partners can act without a meeting with the written consent of holders of 75% or more of the percentage interests of the partners.

Transferability of Interests

        Boston Properties, Inc. may not transfer any of its general partner interest or withdraw as general partner of BPLP or transfer any of its common units, except in certain specifically identified types of transactions, including under certain circumstances in the event of a merger, consolidation or sale of all or substantially all of the assets of Boston Properties, Inc.

        Generally, common units may be transferred without the consent of Boston Properties, Inc. as general partner. However, as general partner, Boston Properties, Inc., in its sole discretion, may or may not consent to the admission as a limited partner any transferee of common units. If Boston Properties, Inc., as general partner, does not consent to the admission of a transferee, the transferee will be an assignee of an economic interest in BPLP but will not be a holder of common units for any other purpose; accordingly, the assignee will not be permitted to vote on any affairs or issues on which a limited partner may vote.

83


Issuance of Additional Units

        Boston Properties, Inc., as general partner, is authorized, in its sole discretion and without limited partner approval, to cause us to issue additional common units, preferred units and other equity securities of BPLP for any partnership purpose at any time to the limited partners or to other persons on terms established by it, as general partner.

Redemption Rights

        Pursuant to the partnership agreement, the limited partners (other than Boston Properties, Inc.) have redemption rights which, subject to certain limitations, enable them to cause us to redeem each unit of limited partnership interest for cash equal to the market value of a share of common stock of Boston Properties, Inc. or, at Boston Properties, Inc.'s election, as general partner, Boston Properties, Inc. may purchase each unit of limited partnership interest offered for redemption for cash or one share of common stock of Boston Properties, Inc.

Management Liability and Indemnification

        Our partnership agreement generally provides that Boston Properties, Inc., as general partner, will incur no liability to BPLP or any limited partner for losses sustained or liabilities incurred as a result of errors in judgment or of any act or omission if Boston Properties, Inc. acted in good faith. In addition, Boston Properties, Inc. is not responsible for any misconduct or negligence on the part of its agents provided they appointed their agents in good faith. Boston Properties, Inc., as general partner, may consult with legal counsel, accountants, appraisers, management consultants, investment bankers and other consultants and advisors. Any action Boston Properties, Inc. takes or omits to take in reliance upon the opinion of these professionals and experts, as to matters that Boston Properties, Inc. reasonably believes to be within their professional or expert competence, shall be conclusively presumed to have been done or omitted in good faith and in accordance with their opinion. Our partnership agreement also provides for the indemnification of Boston Properties, Inc., as general partner, of its directors and officers, and of other persons as Boston Properties, Inc. may from time to time designate, against any and all losses, claims, damages, liabilities, expenses, judgments, fines, settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings involving these indemnified persons that relate to the operations of BPLP.

Amendment

        Amendments to our partnership agreement may be proposed by Boston Properties, Inc., as general partner, or by limited partners holding 20% or more of the partnership interests. Generally, amendments require approval of Boston Properties, Inc., as general partner, and the consent of a majority of the holders of common units. Amendments that would, among other things, convert a limited partner's interest into a general partner's interest, modify the limited liability of any limited partner, alter the interest of any limited partner in profits, losses or distributions, alter or modify the redemption right described herein, or cause the termination of BPLP at a time inconsistent with the terms of our partnership agreement, must be approved by Boston Properties, Inc., as general partner, and each limited partner that would be adversely affected by the amendment.

Management Fees and Expenses

        Boston Properties, Inc. does not receive any compensation for its services as our general partner. However, we will reimburse Boston Properties, Inc., as general partner, for all expenses incurred relating to the ongoing operation of BPLP. Additionally, as a partner in BPLP, Boston Properties, Inc. has a right to allocations and distributions from BPLP in respect of the common units and preferred units it holds.

84


Distributions and Allocations

        The partnership agreement provides that we will distribute all available cash (as defined in the partnership agreement) on at least a quarterly basis, in amounts determined by Boston Properties, Inc., as the general partner, in its sole discretion, to the limited partners in accordance with their respective percentage interests in BPLP. Upon liquidation of BPLP, after payment of, or adequate provision for, our debts and obligations, including any partner loans, any of our remaining assets will be distributed to all limited partners with positive capital accounts in accordance with their respective positive capital account balances.

        Our profit and loss for each fiscal year generally will be allocated among the limited partners in accordance with their respective interest in BPLP. Taxable income and loss will be allocated in the same manner, subject to compliance with the provisions of the Internal Revenue Code of 1986, as amended, sections 704(b) and 704(c) and the Treasury Regulations promulgated thereunder.

Preferred Units

        Our preferred units have the rights, preferences and other privileges (including the right to convert into our common units) as are set forth in amendments to the limited partnership agreement of BPLP. As of February 19, 2003, we had two series of preferred units outstanding. The Series One preferred units have an aggregate liquidation preference of approximately $80.9 million and are entitled to a preferred distribution at a rate of 7.25% per annum, payable quarterly. Series One units are convertible into common units at the rate of $38.25 per common unit at the holder's election at any time. We have the right to convert into common units all or part of the Series One units on or after June 30, 2003, if the common stock of Boston Properties, Inc. at the time of our election is trading at a price of at least $42.08 per share.

        The Series Two preferred units have an aggregate liquidation preference of approximately $270.0 million. The Series Two units are convertible, at the holder's election, into common units at a conversion price of $38.10 per common unit. Distributions on the Series Two units are payable quarterly and generally accrue at rates of: 6.5% through December 31, 2002; 7.0% until May 12, 2009; and 6.0% thereafter. If distributions on the number of common units into which the Series Two units are convertible are greater than distributions calculated using the rates described in the preceding sentence for the applicable quarterly period, then the greater distributions are payable instead. The terms of the Series Two units provide that they may be redeemed for cash in six annual tranches, beginning on May 12, 2009, at the election of Boston Properties, Inc., as our general partner, or at the election of the holders. Boston Properties, Inc., as general partner, also has the right to convert into common units of BPLP any Series Two units that are not redeemed when they are eligible for redemption.

Term

        BPLP will continue until December 31, 2095, or until sooner dissolved upon (i) withdrawal of Boston Properties, Inc., the general partner (unless the remaining partners elect to continue BPLP), (ii) through December 31, 2055, an election to dissolve BPLP made by Boston Properties, Inc., as general partner, with the consent of the limited partners (including Boston Properties, Inc.) holding 85% of the interests in the Company, (iii) on or after January 1, 2056, an election to dissolve BPLP made by Boston Properties, Inc., as general partner, in its sole and absolute discretion, (iv) entry of a decree of judicial dissolution, (v) the sale of all or substantially all of our assets and properties, or (vi) a final and non-appealable judgment ruling Boston Properties, Inc., as general partner, bankrupt or insolvent (unless the limited partners elect to continue BPLP prior to the entry of such order or judgment).

85


Tax Matters

        Pursuant to our limited partnership agreement, Boston Properties, Inc. will be our tax matters partner and, as such will have authority to handle tax audits and to make tax elections under the Internal Revenue Code of 1986, as amended, on our behalf.


Item 12.    Indemnification of Directors and Officers

        We are managed by Boston Properties, Inc., which serves as our general partner.

        Boston Properties, Inc.'s certificate of incorporation generally limits the liability of its directors of Boston Properties, Inc. to the fullest extent permitted by Delaware law, as it now exists or may in the future be amended. The Delaware General Corporation Law permits a corporation to indemnify its directors, officers, employees or agents and expressly provides that the indemnification provided for under the Delaware General Corporation Law shall not be deemed exclusive of any indemnification right under any bylaw, vote of stockholders or disinterested directors, or otherwise. Delaware law permits indemnification against expenses and certain other liabilities arising out of legal actions brought or threatened against such persons for their conduct on behalf of a corporation, provided that each such person acted in good faith and in a manner that he or she reasonably believed was in or not opposed to the corporation's best interests and, in the case of a criminal proceeding, provided such person had no reasonable cause to believe his or her conduct was unlawful. Delaware law does not allow indemnification of directors in the case of an action by or in the right of a corporation unless the directors successfully defend the action or indemnification is ordered by the court.

        Boston Properties, Inc.'s bylaws provide that its directors and officers will be, and, in the discretion of its board of directors, non-officer employees may be, indemnified by Boston Properties, Inc. to the fullest extent authorized by Delaware law, as it now exists or may in the future be amended, against all expenses and liabilities actually and reasonably incurred in connection with service for or on behalf of Boston Properties, Inc. The bylaws of Boston Properties, Inc. also provide that the right of directors and officers to indemnification shall be a contract right and shall not be exclusive of any other right now possessed or hereafter acquired under any bylaw, agreement, vote of stockholders, or otherwise.

        The certificate of incorporation of Boston Properties, Inc. contains a provision permitted by Delaware law that generally eliminates the personal liability of directors for monetary damages for breaches of their fiduciary duty, including breaches involving negligence or gross negligence in business combinations, unless the director has breached his or her duty of loyalty, failed to act in good faith, engaged in intentional misconduct or a knowing violation of law, paid a dividend or approved a stock repurchase in violation of the Delaware General Corporation Law or obtained an improper personal benefit. This provision does not alter a director's liability under the federal securities laws. In addition, this provision does not affect the availability of equitable remedies, such as an injunction or rescission, for breach of fiduciary duty.

        Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling Boston Properties, Inc. pursuant to the foregoing provisions, Boston Properties, Inc. has been informed that in the opinion of the staff of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is therefore unenforceable.

        Boston Properties, Inc. has entered into indemnification agreements with each of its directors and executive officers. The indemnification agreements require, among other things, that Boston Properties, Inc. indemnify its directors and executive officers to the fullest extent permitted by law and advance to its directors and executive officers all related expenses, subject to reimbursement if it is subsequently determined that indemnification is not permitted. Under these agreements, Boston Properties, Inc. must also indemnify and advance all expenses incurred by its directors and executive

To the Partners of
Boston Properties Limited Partnership:

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of Boston Properties Limited Partnership (the "Operating Partnership") at December 31, 2002 and 2001, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2002 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the accompanying index presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. These financial statements and financial statement schedule are the responsibility of the Operating Partnership's management; our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits. We conducted our audits of these statements in accordance with auditing standards generally accepted in the United States of America, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 22 to the consolidated financial statements, the Operating Partnership, on January 1, 2001, adopted Statement of Financial Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging Activities", as amended and interpreted. Also, as discussed in Note 23 to the consolidated financial statements, on January 1, 2002, the Operating Partnership adopted the provisions of Statement of Financial Accounting Standards No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets".

BOSTON PROPERTIES LIMITED PARTNERSHIP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.    Organization and Basis of Presentation

Organization

Boston Properties, Inc. (the "Company"), a Delaware corporation, is a self-administered and self-managed real estate investment trust ("REIT"). Boston Properties, Inc. is the sole general partner of Boston Properties Limited Partnership (the "Operating Partnership") and at December 31, 2002, owned an approximate 76.3% (75.0% at December 31, 2001) general and limited partnership interest in the Operating Partnership. Partnership interests in the Operating Partnership are denominated as "common units of partnership interest" (also referred to as "OP Units") or "preferred units of partnership interest" (also referred to as "Preferred Units"). All references to OP Units and Preferred Units exclude such units held by the Company. A holder of an OP Unit may present such OP Unit to the Operating Partnership for redemption at any time (subject to restrictions agreed upon at the issuance of OP Units to particular holders that may restrict such right for a period of time, generally one year from issuance). Upon presentation of an OP Unit for redemption, the Operating Partnership must redeem such OP Unit for cash equal to the then value of a share of common stock of the Company ("Common Stock"), except that the Company may, at its election, in lieu of a cash redemption, acquire such OP Unit for one share of Common Stock. Because the number of shares of Common Stock outstanding at all times equals the number of OP Units that the Company owns, one share of Common Stock is generally the economic equivalent of one OP Unit, and the quarterly distribution that may be paid to the holder of an OP Unit equals the quarterly dividend that may be paid to the holder of a share of Common Stock. Each series of Preferred Units bears a distribution that is set in accordance with an amendment to the partnership agreement of the Operating Partnership. Preferred Units may also be convertible into OP Units at the election of the holder thereof or the Company, subject to the terms of such Preferred Units.

Properties

At December 31, 2002, the Operating Partnership owned or had interests in a portfolio of 142 commercial real estate properties (147 properties at December 31, 2001) (the "Properties") aggregating more than 42.4 million net rentable square feet (including six properties under construction totaling approximately 2.8 million net rentable square feet). The Properties consist of 133 office properties, including 105 Class A office properties and 28 Office/Technical properties; four industrial properties; three hotels; two retail properties; and structured parking for 20,710 vehicles containing approximately 6.7 million square feet. In addition, the Company owns, controls or has interests in 41 parcels of land totaling 539.6 acres (which will support approximately 8.8 million net rentable square feet of development). The Operating Partnership 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 Operating Partnership considers Office/Technical properties to be properties that support office, research and development and other technical uses.

F-17

Basis of Presentation

The consolidated financial statements of the Operating Partnership include all the accounts of the Operating Partnership, and consolidated subsidiaries. All significant intercompany balances and transactions have been eliminated.

2.    Summary of Significant Accounting Policies

Real Estate

Real estate is stated at depreciated cost, which in the opinion of management is not in excess of the individual property's estimated undiscounted future cash flows, including estimated proceeds from disposition. The cost of buildings and improvements include the purchase price of the property, legal fees and acquisition costs. Certain qualifying costs related to development properties are capitalized. Capitalized development costs include interest, wages, property taxes, insurance and other project costs incurred during the period of development.

The Operating Partnership periodically reviews its properties to determine if their carrying amounts will be recovered from future operating cash flows. 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 are considered on an undiscounted basis in the analysis that the Operating Partnership conducts to determine whether an asset has been impaired, the Operating Partnership's established strategy of holding properties over the long term directly decreases the likelihood of recording an impairment loss. If the Operating Partnership's strategy changes or market conditions otherwise dictate an earlier sale date, an impairment loss may be recognized. If the Operating Partnership determines that an impairment has occurred, the affected assets must be reduced to their fair value. No such impairment losses have been recognized to date.

The costs of land and buildings under development include specifically identifiable costs. The capitalized costs include pre-construction costs essential to the development of the property, development costs, construction costs, interest costs, real estate taxes, salaries and related costs and other costs incurred during the period of development. The Operating Partnership ceases cost capitalization when the property is held available for occupancy upon substantial completion of tenant improvements, but no later than one year from the completion of major construction activity. Interest costs capitalized for the years ended December 31, 2002, 2001 and 2000 were $22.5 million, $59.3 million and $37.7 million, respectively. Salaries and related costs capitalized for the years ended December 31, 2002, 2001 and 2000 were $4.4 million, $5.8 million and $4.9 million, respectively.

The Operating Partnership accounts for properties as held for sale under the provisions of Statement of Financial Accounting Standards ("SFAS") No. 144, "Accounting for the Impairment

F-18


or Disposal of Long-Lived Assets", which typically occurs upon the execution of a purchase and sale agreement. Upon determining that a property is held for sale, the Operating Partnership discontinues depreciating the property and reflects the property at the lower of its carrying amount or fair value less the cost to sell in its consolidated balance sheets.

Expenditures for repairs and maintenance are charged to operations as incurred. Significant betterments are capitalized. When assets are sold or retired, their costs and related accumulated depreciation are removed from the accounts with the resulting gains or losses reflected in net income or loss for the period.

Depreciation is computed on the straight-line basis over the estimated useful lives of the assets as follows:

 
    
Land improvements   25 to 40 years
Buildings and improvements   10 to 40 years
Tenant improvements   Shorter of useful life or terms of related lease
Furniture, fixtures, and equipment   3 to 7 years

Cash and Cash Equivalents

Cash and cash equivalents consist of cash on hand and investments with maturities of three months or less from the date of purchase. The majority of the Operating Partnership's cash and cash equivalents are held at major commercial banks which may at times exceed the Federal Deposit Insurance Corporation limit of $100,000. The Operating Partnership has not experienced any losses to date on its invested cash.

Cash held in Escrows

Escrows include amounts established pursuant to various agreements for real estate purchase and sale transactions, security deposits, property taxes, insurance and other costs.

Investments in Securities

The Operating Partnership accounts for investments in securities of publicly traded companies in accordance with Statement of Financial Accounting Standards ("SFAS") No. 115 "Accounting for Certain Investments in Debt and Equity Investments" and has classified the securities as available-for-sale. Investments in securities of non-publicly traded companies are recorded at cost, as they are not considered marketable under SFAS No. 115. During the years ended December 31, 2002 and 2001, the Operating Partnership realized losses totaling $4.3 million and $6.5 million related to the write-down of securities of three technology companies. The Operating Partnership determined that the decline in the fair value of these securities was other than temporary as defined by SFAS No. 115.

F-19


Tenant and other receivables

Tenant and other receivables are expected to be collected within one year and are reported net of estimated unrecoverable amounts of approximately $3.7 million and $2.4 million at December 31, 2002 and 2001, respectively.

Deferred Charges

Deferred charges include leasing costs and financing costs. Direct and incremental fees and costs incurred in the successful negotiation of leases, including brokerage, legal, internal leasing employee salaries and other costs have been deferred and are being amortized on a straight-line basis over the terms of the respective leases. Internal leasing salaries and related costs capitalized for the years ended December 31, 2002, 2001 and 2000 were approximately $0.7 million, $0.8 million and $0.2 million, respectively. External fees and costs incurred to obtain financing have been deferred and are being amortized over the terms of the respective loans on a basis that approximates the effective interest method and are included with interest expense. Unamortized financing and leasing costs are charged to expense upon the early repayment or significant modification of the financing or upon the early termination of the lease, respectively. Fully amortized deferred charges are removed from the books upon the expiration of the lease or maturity of the debt.

Investments in Unconsolidated Joint Ventures

The Operating Partnership accounts for its investments in joint ventures, which it does not control, using the equity method of accounting. Under the equity method of accounting, the net equity investment of the Operating Partnership is reflected on the consolidated balance sheets, and the Operating Partnership's 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, the Operating Partnership's 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.

To the extent that the Operating Partnership contributes assets to a joint venture, the Operating Partnership's investment in joint venture is recorded at the Operating Partnership's cost basis in the assets that were contributed to the joint venture. To the extent that the Operating Partnership's cost basis is different than the basis reflected at the joint venture level, the basis difference is amortized over the life of the related asset and included in the Operating Partnership's share of equity in net income of the joint venture. In accordance with the provisions of Statement of Position 78-9 "Accounting for Investments in Real Estate Ventures", the Operating Partnership will recognize gains on the contribution of real estate to

F-20


joint ventures, relating solely to the outside partner's interest, to the extent the economic substance of the transaction is a sale.

The Operating Partnership serves as property manager for the joint ventures. The Operating Partnership serves as the development manager for the joint ventures currently under development. The profit on development fees received from joint ventures is recognized to the extent attributable to the outside interests in the joint ventures. The Operating Partnership has recognized development and management fee income earned from its joint ventures of approximately $5.0 million, $3.9 million and $2.1 million for the years ended December 31, 2002, 2001 and 2000, respectively.

Revenue Recognition

Base rental revenue is reported on a straight-line basis over the terms of the respective leases. The impact of the straight-line rent adjustment increased revenue by $51.0 million, $27.8 million and $12.7 million for the years ended December 31, 2002, 2001 and 2000, respectively. Accrued rental income represents rental income earned in excess of rent payments received pursuant to the terms of the individual lease agreements. The Operating Partnership maintains an allowance for doubtful accounts against tenant and other receivables for estimated losses resulting from the inability of its tenants to make required rent payments. The computation of this allowance is based on the tenants' payment history and current credit status. The Operating Partnership also maintains 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. The credit risk is mitigated by the high quality of the Operating Partnership's tenant base, review of the tenant's risk profile prior to lease execution and continual monitoring of the Operating Partnership's 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.

Development fees are recognized ratably over the period of development. Management fees are recognized as revenue as they are earned.

The estimated fair value of warrants received in conjunction with communications license agreements are recognized over the ten-year effective terms of the license agreements.

The Operating Partnership recognizes gains on sales of real estate pursuant to the provisions of SFAS No. 66 "Accounting for Sales of Real Estate". The specific timing of a sale is measured against various criteria in SFAS No. 66 related to the terms of the transaction and any continuing involvement in the form of management or financial assistance associated with the property. If the sales criteria are not met, the Operating Partnership defers gain recognition

F-21


and accounts for the continued operations of the property by applying the finance, installment or cost recovery methods, as appropriate, until the sales criteria are met.

Interest Expense and Interest Rate Protection Agreements

Interest expense on fixed rate debt with predetermined periodic rate increases is computed using the effective interest method over the terms of the respective loans.

From time to time, the Operating Partnership enters into certain interest rate protection agreements to reduce the impact of changes in interest rates on its variable rate debt or in anticipation of issuing fixed rate debt. The fair value of these agreements is reflected on the Consolidated Balance Sheets. Changes in the fair value of these agreements are recorded in the Consolidated Statements of Operations to the extent the agreements are not effective for accounting purposes.

Earnings Per Common Unit

Basic earnings per common unit is computed by dividing net income available to common unitholders by the weighted average number of common units (including redeemable common units) outstanding during the year. Diluted earnings per common unit reflects the potential dilution that could occur from units issuable through parent stock-based compensation including options and conversion of preferred units of the Operating Partnership.

Fair Value of Financial Instruments

The carrying values of cash and cash equivalents, escrows, receivables, accounts payable, accrued expenses and other assets and liabilities are reasonable estimates of their fair values because of the short maturities of these instruments. The fair value of the Operating Partnership's long-term indebtedness, which is based on the estimates of management and on rates currently quoted and rates currently prevailing for comparable loans and instruments of comparable maturities, exceeds the aggregate carrying value by approximately $172.5 million at December 31, 2002.

Income Taxes

The partners are required to report their respective share of the Operating Partnership's taxable income or loss on their respective income tax returns and are liable for any related taxes thereon. Accordingly, the only provision for income taxes in the accompanying consolidated financial statements relates to the Operating Partnership's consolidated taxable REIT subsidiaries.

In January 2002, the Operating Partnership formed a taxable REIT subsidiary ("TRS"), IXP, Inc. (IXP) which acts as a captive insurance company to provide earthquake re-insurance coverage

F-22


for the Operating Partnership's Greater San Francisco properties. The accounts of IXP are consolidated within the Operating Partnership. The captive TRS is subject to tax at the federal and state level, and accordingly, the Operating Partnership has recorded a tax provision of $0.1 million for the year ended December 31, 2002 in the Operating Partnership's Consolidated Statements of Operations.

Effective July 1, 2002, the Operating Partnership restructured the leases with respect to ownership of its three hotel properties by forming a TRS. The hotel TRS, a wholly owned subsidiary of the Operating Partnership, is the lessee pursuant to new leases for each of the hotel properties. As lessor, the Operating Partnership is entitled to a percentage of gross receipts from the hotel properties. Marriott International, Inc. will continue to manage the hotel properties under the Marriott® name and under terms of the existing management agreements. In connection with the restructuring, the revenue and expenses of the hotel properties are being reflected in the Operating Partnership's Consolidated Statements of Operations. The hotel TRS is subject to tax at the federal and state level, and accordingly, the Operating Partnership has recorded a tax provision of $0.4 million for the six months ended December 31, 2002 in the Operating Partnership's Consolidated Statements of Operations.

The Operating Partnership had previously leased its three in-service hotel properties, pursuant to leases with a participation in the gross receipts of such hotel properties, to a lessee ("ZL Hotel LLC") in which Messrs. Zuckerman and Linde, the Chairman of the Board and Chief Executive Officer of the Company, respectively, are the sole member-managers. Marriott International, Inc. manages these hotel properties under the Marriott® name pursuant to management agreements with the lessee. Rental revenue from these leases totaled approximately $12.2 million for the six-month period in 2002 prior to the formation of the hotel TRS and $31.3 million and $38.1 million for the years ended December 31, 2001 and 2000, respectively.

The net difference between the tax basis and the reported amounts of the Operating Partnership's assets and liabilities is approximately $1.7 billion and $1.2 billion as of December 31, 2002 and 2001, respectively.

Certain entities included in the Operating Partnership's consolidated financial statements are subject to certain state and local taxes. These taxes are recorded as operating expenses in the accompanying consolidated financial statements.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. These estimates include such items as depreciation and allowances for doubtful accounts. Actual results could differ from those estimates.

6.    Mortgage Notes Payable

The Operating Partnership had outstanding mortgage notes payable totaling $4.3 billion as of December 31, 2002, each collateralized by one or more buildings and related land included in real estate assets. The mortgage notes payable are generally due in monthly installments and mature at various dates through August 1, 2021.

Fixed rate mortgage notes payable totaled approximately $3.1 billion and $3.4 billion at December 31, 2002 and 2001, respectively, with interest rates ranging from 6.40% to 9.65% (averaging 7.17% and 7.27% at December 31, 2002 and 2001, respectively).

Variable rate mortgage notes payable (including construction loans payable) totaled approximately $1.1 billion and $866.0 million at December 31, 2002 and 2001, respectively, with interest rates ranging from 1.25% above the London Interbank Offered Rate ("LIBOR") (LIBOR was 1.38% and 1.87% at December 31, 2002 and 2001, respectively) to 1.95% above LIBOR.

At December 31, 2002, the Operating Partnership had outstanding hedge contracts totaling $150.0 million. The hedging agreements provide for a fixed interest rate when LIBOR is less than 5.76% and when LIBOR is between 6.35% and 7.45% and between 7.51% and 9.00% for remaining terms ranging from one to three years per the individual hedging agreements.

A mortgage note payable totaling approximately $115.1 million at December 31, 2001 was subject to periodic scheduled interest rate increases. Interest expense for this mortgage note payable was computed using the effective interest method. A mortgage note payable totaling approximately $69.3 million at December 31, 2002 and two mortgage notes payable totaling approximately $220.7 million at December 31, 2001, have been accounted for at their fair value on the date the mortgage loans were assumed. The impact of using these accounting methods decreased interest expense by $2.2 million, $1.7 million and $3.6 million for the years ended

F-27


December 31, 2002, 2001 and 2000, respectively. The cumulative liability related to these accounting methods was $5.8 million and $7.9 million at December 31, 2002 and 2001, respectively, and is included in mortgage notes payable.

Combined aggregate principal payments of mortgage notes payable at December 31, 2002 are as follows:

7.    Unsecured Senior Notes

On December 13, 2002, the Operating Partnership closed an unregistered offering of $750.0 million in aggregate principal amount of its 6.25% senior unsecured notes due 2013. The notes were priced at 99.65% of their face amount to yield 6.296%. The notes have been reflected net of discount of $2.6 million in the Consolidated Balance Sheets. The Operating Partnership used the net proceeds to pay down its unsecured bridge loan incurred in connection with its September 2002 acquisition of 399 Park Avenue. In connection with the offering, the Operating Partnership terminated treasury rate lock agreements at a cost of approximately $3.5 million that are being amortized over the term of the notes as an adjustment to interest expense.

The indenture relating to the unsecured senior notes contain certain financial restrictions and requirements, 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 1.50, and (4) an unencumbered asset value to less than 150% of unsecured debt. At December 31, 2002, the Operating Partnership was in compliance with each of these financial restrictions and requirements.

8.    Unsecured Bridge Loan

On September 25, 2002, the Operating Partnership obtained unsecured bridge financing totaling $1.0 billion (the "Unsecured Bridge Loan") in connection with the acquisition of 399 Park Avenue. During 2002, the Operating Partnership 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 and currently bears interest at a variable rate of Eurodollar + 1.45% (2.89% for the contract in effect at December 31, 2002). The Unsecured

F-28


Bridge Loan matures in September 2003 and may be prepaid at any time prior to its maturity without a prepayment penalty.

The terms of the Unsecured Bridge Loan require that the Operating Partnership maintain a number of customary financial and other covenants on an ongoing basis including among other things, (1) unsecured loan-to-value ratio against total borrowing base not to exceed 55%, unless the Company's leverage ratio exceeds 60%, in which case it is not to exceed 50%, (2) a secured debt leverage ratio not to exceed 55%, (3) debt service coverage ratio of 1.40 for the Operating Partnership's borrowing base, or 1.50 if the Operating Partnership's leverage ratio equals or exceeds 60%, a fixed charge ratio of 1.30, and a debt service coverage ratio of 1.50 (4) a leverage ratio not to exceed 60%, however for five consecutive quarters (not including the two quarters prior to expiration) leverage can go to 65% (5) limitations on additional indebtedness and stockholder distributions, and (6) a minimum net worth requirement. At December 31, 2002, the Operating Partnership was in compliance with each of these financial and other covenant requirements.

9.    Unsecured Line of Credit

As of December 31, 2002, the Operating Partnership had an agreement for a $605.0 million unsecured revolving credit facility (the "Unsecured Line of Credit") maturing in March 2003. Outstanding balances under the Unsecured Line of Credit currently bear interest at a floating rate based on an increase over Eurodollar from 105 to 170 basis points or an increase over the lender's prime rate from zero to 75 basis points, depending upon the Operating Partnership's applicable leverage ratio. The Unsecured Line of Credit requires payments of interest only.

The Operating Partnership had an outstanding balance on the Unsecured Line of Credit of $173.9 million at December 31, 2002 of which approximately $146.9 million is collateralized by the Operating Partnership's 875 Third Avenue property and is included in Mortgage Notes Payable. There was no outstanding balance at December 31, 2001. The weighted-average balance outstanding was approximately $15.2 million and $11.3 million during the year ended December 31, 2002 and 2001, respectively. The weighted-average interest rate on amounts outstanding was approximately 3.03% and 5.49% during the year ended December 31, 2002 and 2001, respectively.

The terms of the Unsecured Line of Credit require that the Operating Partnership maintain a number of customary financial and other covenants on an ongoing basis including among other things, (1) unsecured loan-to-value ratio against total borrowing base not to exceed 55%, unless the Operating Partnership's leverage ratio exceeds 60%, in which case it is not to exceed 50%, (2) a secured debt leverage ratio not to exceed 55%, (3) debt service coverage ratio of 1.40 for the Company's borrowing base, or 1.50 if the Operating Partnership's leverage ratio equals or exceeds 60%, a fixed charge ratio of 1.30, and a debt service coverage ratio of

F-29


1.50 (4) a leverage ratio not to exceed 60%, however for five consecutive quarters (not including the two quarters prior to expiration) leverage can go to 65% (5) limitations on additional indebtedness and stockholder distributions, and (6) a minimum net worth requirement. At December 31, 2002, the Operating Partnership was in compliance with each of these financial and other covenant requirements.

10.    Commitments and Contingencies

General

The Operating Partnership has letter of credit and performance obligations of approximately $39.3 million primarily related to its wholly owned subsidiary IXP and certain other development and lender requirements.

The Operating Partnership has indebtedness guarantee obligations with lenders primarily related to construction loans. At December 31, 2002, the Operating Partnership had obligations outstanding totaling approximately $2.8 million in excess of its share of indebtedness related to the construction loan of a joint venture property.

The Operating Partnership'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 Operating Partnership is not compelled to purchase the interest of its outside joint venture partners.

Concentrations of Credit Risk

Management of the Operating Partnership performs ongoing credit evaluations of tenants and may require tenants to provide some form of credit support such as corporate guarantees and/or other financial guarantees. Although the Operating Partnership's properties are geographically diverse and the tenants operate in a variety of industries, to the extent the Operating Partnership has a significant concentration of rental revenue from any single tenant, the inability of that tenant to make its lease payments could have an adverse effect on the Operating Partnership.

Insurance

The Operating Partnership 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. The Operating Partnership believes that all of its properties are adequately insured. The property insurance that the Operating Partnership maintains for its properties has historically been on an "all risk" basis, which until 2002 included losses caused by acts of terrorism. Following the terrorist activity of September 11, 2001 and the resulting uncertainty in the insurance market, insurance companies generally excluded insurance against acts of terrorism

F-30


from their "all risk" policies. As a result the Operating Partnership's "all risk" insurance coverage currently contains specific exclusions for losses attributable to acts of terrorism. In light of this development, in 2002 the Operating Partnership purchased stand-alone terrorism insurance on a portfolio-wide basis with annual aggregate limits that the Operating Partnership considers commercially reasonable, considering the availability and cost of such coverage. The federal Terrorism Risk Insurance Act, enacted in November 2002, requires regulated insurers to make available coverage for certified acts of terrorism (as defined by the statute) under property insurance policies, but the Operating Partnership cannot currently anticipate whether the scope and cost of such coverage will compare favorably to stand-alone terrorism insurance, and thus whether it will be commercially reasonable for the Operating Partnership to change its coverage for acts of terrorism going forward. The Operating Partnership will continue to monitor the state of the insurance market, but does not currently expect that coverage for acts of terrorism on terms comparable to pre-2002 policies will become available on commercially reasonable terms.

The Operating Partnership 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 it believes are commercially reasonable. However, the amount of the Operating Partnership'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 Operating Partnership may be able to purchase on commercially reasonable terms may be reduced. In addition, the Operating Partnership may discontinue earthquake insurance on some or all of its properties in the future if the premiums exceed the Operating Partnership's estimation of the value of the coverage.

In January 2002, the Operating Partnership formed a wholly-owned insurance subsidiary, IXP, Inc. ("IXP"), to act as a captive insurance company and be one of the elements of its overall insurance program. IXP has acted as a reinsurer for the Operating Partnership's primary carrier with respect to a portion of its earthquake insurance coverage for its Greater San Francisco properties. In the future IXP may provide additional or different coverage, as a reinsurer or a primary insurer, depending on the availability and cost of third party insurance in the marketplace and the level of self insurance that the Operating Partnership believes is commercially reasonable. The accounts of IXP are consolidated within the Operating Partnership.

There are other types of losses, such as from wars, acts of bio-terrorism or the presence of mold at the Operating Partnership's properties, for which the Operating Partnership 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 Operating Partnership experiences a loss that is uninsured or that exceeds policy limits, the Operating Partnership could lose the capital invested in the damaged properties, as well as the anticipated future revenues from

F-31


those properties. Depending on the specific circumstances of each affected property, it is possible that the Operating Partnership could be liable for mortgage indebtedness or other obligations related to the property. Any such loss could materially and adversely affect the Operating Partnership's business and financial condition and results of operations.

Legal Matters

The Operating Partnership is subject to various legal proceedings and claims that arise in the ordinary course of business. These matters are generally covered by insurance. Management believes that the final outcome of such matters will not have a material adverse effect on the financial position, results of operations or liquidity of the Operating Partnership.

Environmental Matters

It is the Operating Partnership's policy to retain independent environmental consultants to conduct or update Phase I environmental assessments (which generally do not involve invasive techniques such as soil or ground water sampling) and asbestos surveys with respect to its properties. These pre-purchase environmental assessments have not revealed environmental conditions that the Operating Partnership believes will have a material adverse effect on its business, assets or results of operations, and the Operating Partnership is not otherwise aware of environmental conditions with respect to its properties which the Operating Partnership believes would have such a material adverse effect. However, from time to time pre-existing environmental conditions at its properties have required environmental testing and/or regulatory filings.

In February 1999, one of the Operating Partnership's affiliates acquired from Exxon Corporation a property in Massachusetts that was formerly used as a petroleum bulk storage and distribution facility and was known by the state regulatory authority to contain soil and groundwater contamination. The Operating Partnership recently completed development of an office park on the property. The Operating Partnership's affiliate engaged a specially licensed environmental consultant to oversee the management of contaminated soil and groundwater that was disturbed in the course of construction. Pursuant to the property acquisition agreement, Exxon agreed to (1) bear the liability arising from releases or discharges of oil and hazardous substances which occurred at the site prior to the Operating Partnership's ownership, (2) continue remediating such releases and discharges as necessary and appropriate to comply with applicable requirements, and (3) indemnify the Operating Partnership's affiliate for certain losses arising from preexisting site conditions. Any indemnity claim may be subject to various defenses.

Environmental investigations at two of the Operating Partnership's properties in Massachusetts have identified groundwater contamination migrating from off-site source properties. In both cases the Operating Partnership engaged a specially licensed environmental consultant to

F-32


perform the necessary investigations and assessments and to prepare submittals to the state regulatory authority, including Downgradient Property Status Opinions. The environmental consultant concluded that the properties qualify for Downgradient Property Status under the state regulatory program, which eliminates certain deadlines for conducting response actions at a site. The Operating Partnership also believes that these properties qualify for liability relief under certain statutory amendments regarding upgradient releases. Although the Operating Partnership believes that the current or former owners of the upgradient source properties may ultimately be responsible for some or all of the costs of addressing the identified groundwater contamination, the Operating Partnership will take necessary further response actions (if any are required). No such additional response actions are anticipated at this time.

One of the Operating Partnership's affiliates recently acquired a property in Massachusetts where historic groundwater contamination was identified prior to acquisition. The Operating Partnership engaged a specially licensed environmental consultant to perform investigations and to prepare necessary submittals to the state regulatory authority. The environmental consultant has concluded that (1) certain identified groundwater contaminants are migrating to the subject property from an off-site source property and (2) certain other detected contaminants are likely related to a historic release on the subject property. The Operating Partnership has filed a Downgradient Property Status Opinion (described above) with respect to contamination migrating from off-site. The consultant has recommended conducting additional investigations, including the installation of off-site monitoring wells, to determine the nature and extent of contamination potentially associated with the historic use of the subject property. The Operating Partnership's affiliate has authorized such additional investigations and will take necessary further response actions (if any are required).

Some of the Operating Partnership's properties and certain properties owned by the Operating Partnership's affiliates are located in urban, industrial and other previously developed areas where fill or current or historical uses of the areas have caused site contamination. Accordingly, it is sometimes necessary to institute special soil and/or groundwater handling procedures in connection with construction and other property operations in order to achieve regulatory closure and ensure that contaminated materials are addressed in an appropriate manner. In these situations it is the Operating Partnership's practice to investigate the nature and extent of detected contamination and estimate the costs of required response actions and special handling procedures. The Operating Partnership then uses this information as part of its decision-making process with respect to the acquisition and/or development of the property. For example, the Operating Partnership recently acquired a parcel in Massachusetts, formerly used as a quarry/asphalt batching facility, which the Operating Partnership may develop in the future. Pre-purchase testing indicated that the site contains relatively low levels of certain contaminants. The Operating Partnership has engaged a specially licensed environmental consultant to perform an environmental risk characterization and prepare all necessary regulatory submittals. The Operating Partnership anticipates that additional response actions

F-33

necessary to achieve regulatory closure (if any) will be performed in concert with future construction activities. When appropriate, closure documentation will be submitted for public review and comment pursuant to the state regulatory authority's public information process.

The Operating Partnership expects that resolution of the environmental matters relating to the above will not have a material impact on its financial position, results of operations or liquidity.

Development

The Operating Partnership has six properties currently under construction. Commitments to complete these projects totaled approximately $405.9 million at December 31, 2002. Of the remaining commitment, $371.7 million of the costs will be covered under its existing construction loans.

Sale of Property

The Operating Partnership Agreement provides that, until June 23, 2007, the Operating Partnership may not sell or otherwise transfer three designated properties (or a property acquired pursuant to the disposition of a designated property in a non-taxable transaction) in a taxable transaction without the prior written consent of Mr. Mortimer B. Zuckerman, Chairman of the Board of Directors of the Company and Mr. Edward H. Linde, President and Chief Executive Officer of the Company. The Operating Partnership is not required to obtain their consent if each of them does not continue to hold at least a specified percentage of their original OP Units. In connection with the acquisition or contribution of 31 other Properties, the Operating Partnership entered into similar agreements for the benefit of the selling or contributing parties which specifically state the Operating Partnership will not sell or otherwise transfer the Properties in a taxable transaction until specified dates ranging from June 2006 to April 2016.

11.    Minority Interest in Property Partnership

On April 25, 2001, the Operating Partnership acquired Citigroup Center through a venture with a private real estate investment company. This venture is consolidated with the financial results of the Operating Partnership because the Operating Partnership exercises control over the entity that owns the property. The equity interest in the venture that is not owned by the Operating Partnership, totaling approximately $29.9 million and $34.4 million at December 31, 2002 and 2001, respectively is included in Minority Interest in Property Partnership on the accompanying Consolidated Balance Sheets. The minority interest holder's share of income for Citigroup Center is reflective of the Operating Partnership's preferential return on and of its capital.

Operating Partnership Units

Pursuant to the Operating Partnership Agreement, certain limited partners in the Operating Partnership have the right to redeem all or any portion of their interest for cash from the Operating Partnership. However, the Company may elect to acquire the interest by issuing common stock in exchange for their interest. The amount of cash to be paid to the limited partner if the redemption right is exercised and the cash option is elected is based on the trading price of the Company's common stock at that time. Due to the redemption option existing outside the control of the Operating Partnership, such limited partners' units are not included in Partners' Capital.

Preferred Units

Each of the Series I Preferred Units bear a 7.25% preferred distribution on a quarterly basis in arrears. The Series I Preferred Units have a liquidation preference of $34 per unit and are

F-35

convertible into Operating Partnership Units at a rate of $38.25 per unit at the election of the holder. In addition, the Series I Preferred Units are redeemable for Operating Partnership Units at the election of the Operating Partnership on or after June 20, 2003, subject to certain provisions. As of December 31, 2002, 122,147 Series I Preferred Units had been converted into common Operating Partnership Units.

Each of the Series II and III and Series A Parallel Preferred Units bear a preferred distribution at the greater of the distribution rate payable to common unitholders or an increasing rate, ranging from 5.00% to 7.00% per annum with a liquidation preference of $50 per unit and are convertible into Operating Partnership Units at a rate of $38.10 per unit. In addition, the Series II and III and Series A Parallel Preferred Units are redeemable for cash at the election of the holder in six annual tranches beginning on May 12, 2009. The Series A Parallel Preferred Units were converted into common Operating Partnership Units in July 2002. As of December 31, 2002, 645,075 Series II and all Series III Preferred Units had been converted into common Operating Partnership Units.

Each of the Series Z Preferred Units bear a preferred distribution ranging from zero to the distribution rate of an Operating Partnership Unit and were convertible into Operating Partnership Units at a rate of one for one. The Series Z Preferred Units had a liquidation preference of $37.25 per unit. In addition, the Series Z Preferred Units were redeemable for cash at the election of the holder for an amount equal to the greater of the value of a common share of the Company or $37.25 per unit beginning on February 11, 2002. The Series Z Preferred Units were converted into common Operating Partnership Units in March 2002.

Due to the redemption option and the conversion option existing outside the control of the Operating Partnership, such 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 December 31, 2002 and 2001, respectively. Included in preferred distributions in the consolidated statements of operations is accretion of Preferred Units from the value at issuance to the liquidation value.

No one tenant represented more than 10.0% of the Company's total rental revenue for the years ended December 31, 2002, 2001 and 2000.

15.    Segment Reporting

The Operating Partnership has determined that its reportable segments are those that are based on the Operating Partnership's method of internal reporting, which classifies its operations by both geographic area and property type. The Operating Partnership's reportable segments by geographic area are Greater Boston, Greater Washington, D.C., Midtown Manhattan, Greater San Francisco, and New Jersey and Pennsylvania. Segments by property type include: Class A Office, Office/Technical, Industrial and Hotel.

Asset information by reportable segment is not reported, since the Operating Partnership does not use this measure to assess performance; therefore, the depreciation and amortization expenses are not allocated among segments. Development and management services revenue, interest and other revenue, general and administrative expenses, net derivative losses, losses on investments in securities and interest expense are not included in net operating income, as the internal reporting addresses these on a corporate level.

F-39


Net operating income is not a measure of operating results or cash flows from operating activities as measured by accounting principles generally accepted in the United States of America, and it is not indicative of cash available to fund cash needs and should not be considered an alternative to cash flows as a measure of liquidity. All companies may not be using the same definition for net operating income. As discussed in Note 2 and effective as of July 1, 2002, the revenue and expenses of the hotel properties have been included in the operations of the Operating Partnership. The operations of the hotel properties were reflected in the periods prior to July 1, 2002 as a net lease payment in rental revenue and real estate tax expense in property operating expenses.

16.    Extraordinary Items

The Operating Partnership incurred extraordinary losses of $2.4 million and $0.4 million, respectively for the years ended December 31, 2002 and 2000 due to the payment of a prepayment fee and the write-off of unamortized deferred financing costs related to the early extinguishment of certain mortgage notes payable.

17.    Earnings Per Common Unit

Earnings per common unit has been computed pursuant to the provisions of SFAS No. 128. The following table provides a reconciliation of both net income and the number of common units used in the computation of basic earnings per common unit, which utilizes the weighted average number of common units outstanding without regard to the dilutive potential common units, and diluted earnings per common unit, which includes all units, as applicable.

18.    Employee Benefit Plan

Effective January 1, 1985, the predecessor of the Operating Partnership adopted a 401(k) Savings Plan (the "Plan") for its employees. Under the Plan, as amended, employees as defined,

F-43


are eligible to participate in the Plan after they have completed three months of service. Upon formation, the Operating Partnership adopted the Plan and the terms of the Plan.

Effective January 1, 2000, the Operating Partnership amended the Plan by increasing the Operating Partnership's matching contribution to 200% of the first 3% from 200% of the first 2% of participant's eligible earnings contributed (utilizing earnings that are not in excess of $200,000, indexed for inflation) and by eliminating the vesting requirement.

The Plan provides that matching employer contributions are to be determined at the discretion of the Operating Partnership. The Operating Partnership's matching contribution for the years ended December 31, 2002, 2001 and 2000 was $2.0 million, $1.8 million and $1.7 million, respectively.

19.    Stock Option and Incentive Plan and Stock Purchase Plan

The Company has established a stock option and incentive plan, on behalf of certain employees of the Operating Partnership, for the purpose of attracting and retaining qualified executives and rewarding them for superior performance in achieving the Company's business goals and enhancing stockholder value.

Under the plan, the number of shares of Common Stock available for issuance is 14,699,162 shares plus as of the first day of each calendar quarter after January 1, 2000, 9.5% of any net increase since the first day of the preceding calendar quarter in the total number of shares of Common Stock of the Company outstanding, on a fully converted basis (excluding Preferred Stock). At December 31, 2002, the number of shares available for issuance under the plan was 3,192,911.

Options granted under the plan become exercisable over a two, three or five year period and have terms of ten years. All options were granted at the fair market value of the Company's Common Stock at the dates of grant.

The Company issued 52,750, 44,842 and 34,822 shares of restricted stock under the plan during the years ended December 31, 2002, 2001 and 2000, respectively. The shares of restricted stock were valued at approximately $2.0 million ($37.70 per share), $1.8 million ($40.75 per share) and $1.1 million ($30.4375 per share) for the years ended December 31, 2002, 2001 and 2000, respectively. The restricted stock vests over a five-year period, with one-fifth of the shares vesting each year and has been recognized net of amortization as unearned compensation on the consolidated balance sheets. Compensation expense related to the restricted stock totaled $1.2 million, $0.6 million and $0.2 million for the years ended December 31, 2002, 2001 and 2000, respectively.

$37.70-$42.12   4,648,500   7.95 Years   $40.41   1,876,592   $41.59

In addition, the Company had 4,999,346 and 3,397,714 options exercisable at weighted-average exercise prices of $31.37 and $32.11 at December 31, 2002 and 2001, respectively.

The Company adopted the 1999 Non-Qualified Employee Stock Purchase Plan (the "Stock Purchase Plan") to encourage the ownership of Common Stock by eligible employees. The Stock Purchase Plan became effective on January 1, 1999 with an aggregate maximum of 250,000 shares of Common Stock available for issuance. The Stock Purchase Plan provides for eligible employees to purchase at the end of the biannual purchase periods shares of Common Stock for 85% of the average closing price during the last ten business days of the purchase period. The Company issued 8,595, 8,538 and 11,105 shares with the weighted average fair value of the purchase right equal to $33.09 per share, $36.02 per share and $28.15 per share under the Stock Purchase Plan as of December 31, 2002, 2001 and 2000, respectively.

The Company applies Accounting Practice Bulletin No. 25 and related interpretations in accounting for its stock option and stock purchase plans. Accordingly, no compensation cost has been recognized.

The compensation cost under SFAS No. 123 for the stock performance-based plan would have been $9.4 million, $11.7 million and $12.0 million for the years ended December 31, 2002, 2001 and 2000, respectively. Had compensation cost for the Company's grants for stock-based compensation plans been determined consistent with SFAS No. 123, the Operating Partnership's net income available to common unitholders, and net income per common unit for 2002, 2001 and 2000 would approximate the pro forma amounts below:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

22.    Derivative Instruments and Hedging Activities

The Operating Partnership adopted SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities" as amended by SFAS No. 137 and SFAS No. 138 ("SFAS No. 133"), as of January 1, 2001. SFAS No. 133 establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and hedging activities. It requires the recognition of all derivative instruments as assets or liabilities in the Operating Partnership's consolidated balance sheets at fair value. Changes in the fair value of derivative instruments that are not designated as hedges or that do not meet the hedge accounting criteria of SFAS No. 133 are recognized in earnings. For derivatives designated as hedging instruments in qualifying cash flow hedges, the effective portion of changes in fair value of the derivatives are recognized in accumulated other comprehensive income (loss) until the forecasted transactions occur and the ineffective portions are recognized in earnings.

On the date that the Operating Partnership enters into a derivative contract, it designates the derivative as (1) a hedge of the variability of cash flows that are to be received or paid in connection with a recognized liability (a "cash flow" hedge), or (2) an instrument that is held for non-hedging purposes (a "non-hedging" instrument). Changes in the fair value of a derivative that is highly effective as - and that is designated and qualifies as - a cash flow hedge, to the extent that the hedge is effective, are recorded in other comprehensive income, until earnings are affected by the hedged transaction (i.e. until periodic settlements of a variable-rate liability are recorded in earnings). Any hedge ineffectiveness (which represents the amount by which the changes in the fair value of the derivative exceed the variability in the cash flows of the forecasted transaction) is recorded in current-period earnings. Changes in the fair value of non-hedging instruments are reported in current-period earnings.

The Operating Partnership occasionally executes a financial instrument in which a derivative instrument is "embedded." Upon executing the financial instrument, the Operating Partnership assesses whether the economic characteristics of the embedded derivative are clearly and closely related to the economic characteristics of the remaining component of the financial instrument (i.e., the host contract) and whether a separate, non-embedded instrument with the same terms as the embedded instrument would meet the definition of a derivative instrument. When it is determined that (1) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and (2) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument, the embedded derivative is separated from the host contract, carried at fair value, and designated as either (1) a fair-value or cash flow hedge or (2) a trading or non-hedging derivative instrument. However, if the entire contract were to be measured at fair value, with changes in fair value reported in current earnings, or if the Operating Partnership could not reliably identify and measure the embedded derivative for purposes of separating that derivative from its host contract, the entire contract would be carried on the balance sheet at

F-49


fair value and not be designated as a hedging instrument. Pursuant to SFAS No. 137, the Operating Partnership has selected January 1, 1999 as the transition date for embedded derivatives.

The Operating Partnership formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as cash flow hedges to (1) specific assets and liabilities on the balance sheet or (2) forecasted transactions. The Operating Partnership also assesses and documents, both at the hedging instrument's inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows associated with the hedged items. When it is determined that a derivative is not (or has ceased to be) highly effective as a hedge, the Operating Partnership discontinues hedge accounting prospectively, as discussed below.

The Operating Partnership discontinues hedge accounting prospectively when (1) it determines that the derivative is no longer effective in offsetting changes in the cash flows of a hedged item; (2) the derivative expires or is sold, terminated, or exercised; (3) it is no longer probable that the forecasted transaction will occur; or (4) management determines that designating the derivative as a hedging instrument is no longer appropriate.

When the Operating Partnership discontinues hedge accounting because it is no longer probable that the forecasted transaction will occur in the originally expected period, the gain or loss on the derivative remains in accumulated other comprehensive income and is reclassified into earnings when the forecasted transaction affects earnings. However, if it is probable that a forecasted transaction will not occur by the end of the originally specified time period or within an additional two-month period of time thereafter, the gains and losses that were accumulated in other comprehensive income will be recognized immediately in earnings. In all situations in which hedge accounting is discontinued and the derivative remains outstanding, the Operating Partnership will carry the derivative at its fair value on the balance sheet, recognizing changes in the fair value in current-period earnings.

The Operating Partnership entered into interest rate protection agreements during 2000, generally for the purpose of fixing interest rates on variable rate construction loans in order to reduce the budgeted interest costs on the Operating Partnership's development projects, which would translate into higher returns on investment as the development projects come on-line. These interest rate protection agreements expire at varying dates through February 2005. Other derivatives are not linked to specific assets or liabilities but are used by the Operating Partnership to manage risk of the overall portfolio. Amounts included in accumulated other comprehensive loss related to the effective portion of cash flow hedges will be reclassified into earnings over the estimated life of the constructed asset.

F-50


Upon adoption of SFAS No. 133 on January 1, 2001, the Operating Partnership recorded an asset of approximately $0.2 million (included in prepaid expenses and other assets) and recorded a liability of approximately $11.4 million for the fair values of these agreements. The offset for these entries was to a cumulative effect of a change in accounting principle and accumulated other comprehensive loss, respectively. Finally, the Operating Partnership wrote-off deferred charges of approximately $1.6 million as a cumulative effect of a change in accounting principle.

The Operating Partnership's derivatives also include investments in warrants to purchase shares of common stock of other companies. Based on the terms of the warrant agreements, the warrants meet the definition of a derivative and accordingly must be marked to fair value through earnings. The Operating Partnership had been recording the warrants at fair value through accumulated other comprehensive loss as available-for-sale securities under SFAS No. 115. Upon adoption of SFAS No. 133 on January 1, 2001, the Operating Partnership reclassified approximately $6.9 million, the fair value of the warrants, from accumulated other comprehensive loss to a cumulative effect of a change in accounting principle.

During 2001, the Operating Partnership paid the fair value of the swap arrangement and two hedge contracts that were entered into during 2000 and part of 2001 in order to terminate the contracts. In addition, for the year ended December 31, 2001, the Operating Partnership recorded unrealized derivative losses through other comprehensive income of approximately $2.5 million, related to the effective portion of interest rate agreements. The Operating Partnership expects that within the next twelve months it will reclassify into earnings approximately $347,000 of the amount recorded in accumulated other comprehensive loss relating to these agreements.

During 2002, the Operating Partnership entered into treasury rate lock contracts designated and qualifying as a cash flow hedge to reduce its exposure to variability in future cash flows attributable to changes in the Treasury rate relating to a forecasted fixed rate financing. All components of the treasury rate lock agreements were included in the assessment of hedge effectiveness. The amount of hedge ineffectiveness was not material. The Operating Partnership terminated these contracts upon the issuance of the fixed rate debt, and paid approximately $3.5 million, which is reflected in other comprehensive income. The loss reflected in accumulated other comprehensive loss will be reclassified into earnings over the term of the fixed rate debt. The Operating Partnership expects that within the next twelve months it will reclassify into earnings approximately $351,000 of the amount recorded in accumulated other comprehensive loss relating to these agreements.

For the year ended December 31, 2002 and 2001, the Operating Partnership recorded net derivative losses of approximately $11.9 million and $26.5 million through earnings, which represented the total ineffectiveness of all cash flow hedges and other non-hedging

F-51


instruments, the changes in value of the embedded derivatives and the change in value of the warrants. All components of each derivative's gain or loss were included in the assessment of hedge effectiveness, except for the time value of option contracts.

23.    Discontinued Operations and Sales of Real Estate

In October 2001, the Financial Accounting Standards Board (the "FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." SFAS No. 144 supersedes FASB SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of" and the accounting and reporting provisions for disposals of a segment of a business as addressed in APB Opinion No. 30, "Reporting the Results of Operations—Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions". SFAS No. 144 establishes a single accounting model for long-lived assets to be disposed of by sale and addresses various implementation issues of SFAS No. 121. In addition, SFAS No. 144 extends the reporting requirements of discontinued operations to include components of an entity that have either been disposed of or are classified as held for sale. The Operating Partnership adopted SFAS No. 144 as of January 1, 2002.

During 2002, the Operating Partnership disposed of five office/technical properties totaling 347,680 net rentable square feet in Springfield, Virginia, one industrial property totaling 220,213 net rentable square feet in Hayward, California and two Class A office properties totaling 917,459 net rentable square feet in Washington, DC. Due to the Operating Partnership's continuing involvement in the management of the two Washington, DC properties through an agreement with the buyer, these properties are not categorized as discontinued operations in the accompanying consolidated statements of operations. As a result, the gain on sale related to the two Washington, DC properties, totaling approximately $228.9 million, has been reflected under the caption—gains (losses) on sales of real estate, in the consolidated statements of operations.

At December 31, 2002, the Operating Partnership had one Class A office property totaling approximately 711,901 net rentable square feet in Midtown Manhattan, NY designated as held for sale. The Operating Partnership has ceased depreciation of this property, however, due to the Operating Partnership's anticipated continuing involvement in the management of the property after the sale, the Operating Partnership has not categorized this property as discontinued operations in the accompanying consolidated statements of operations.

The Operating Partnership's adoption of SFAS No. 144 resulted in the presentation of the net operating results of these qualifying properties sold during 2002, as income from discontinued operations for all periods presented. In addition, SFAS No. 144 resulted in the gains on sale of these qualifying properties totaling approximately $30.9 million to be reflected as gains on

F-52


sales of real estate from discontinued operations in the accompanying consolidated statements of operations. The adoption of SFAS No. 144 did not have an impact on net income available to common unitholders. SFAS No. 144 only impacted the presentation of these properties within the consolidated statements of operations.

24.    Newly Issued Accounting Standards

In June 2001, the FASB issued SFAS No. 141, "Business Combinations", and SFAS No. 142, "Goodwill and Other Intangible Assets". The provisions of SFAS No. 141 apply to all business combinations initiated after June 30, 2001. SFAS No. 142 becomes effective beginning January 1, 2002. The Operating Partnership adopted both these pronouncements for the year ended December 31, 2002 and neither had a material impact on its results of operations, financial position or liquidity.

In August 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement Obligations". SFAS No. 143 requires an entity to record a liability for an obligation associated with the retirement of an asset at the time the liability is incurred by capitalizing the cost as part of the carrying value of the related asset and depreciating it over the remaining useful life of that asset. The standard is effective beginning January 1, 2003. The changes required by SFAS No. 143 are not expected to have a material impact on the Operating Partnership's results of operations, financial position or liquidity.

In October 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," which addresses how and when to measure impairment on long-lived assets and how to account for long-lived assets that an entity plans to dispose of either through sale, abandonment, exchange, or distribution to owners. The Operating Partnership adopted SFAS No. 144 as of January 1, 2002. See Note 22 for a discussion of the impact on the Operating Partnership from the adoption of SFAS No. 144.

In April 2002, the FASB issued SFAS No. 145, "Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections" which updates, clarifies, and simplifies certain existing accounting pronouncements beginning at various dates in 2002 and 2003. The statement rescinds SFAS No. 4 and SFAS No. 64, which required net gains or losses from the extinguishment of debt to be classified as an extraordinary item in the income statement. The Operating Partnership anticipates that these gains and losses will no longer be classified as extraordinary items as they are not unusual and infrequent in nature. The changes required by SFAS No. 145 are not expected to have a material impact on the Operating Partnership's results of operations, financial position or liquidity.

In July 2002, the FASB issued SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities," which becomes effective beginning January 1, 2003. This statement requires a cost associated with an exit or disposal activity, such as the sale or termination of a line of

F-53


business, the closure of business activities in a particular location, or a change in management structure, to be recorded as a liability at fair value when it becomes probable the cost will be incurred and no future economic benefit will be gained by the Operating Partnership for such termination costs, and costs to consolidate facilities or relocate employees. SFAS No. 146 supersedes Emerging Issues Task Force Issue No. 94-3, "Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity," which in some cases required certain costs to be recognized before a liability was actually incurred. The adoption of this standard is not expected to have a material impact on the Operating Partnership's results of operations, financial position or liquidity.

In December 2002, the FASB issued SFAS No. 148, "Accounting for Stock-Based Compensation—Transition and Disclosure," which provides guidance on how to transition from the intrinsic value method of accounting for stock-based employee compensation under APB No. 25 to SFAS No. 123's fair value method of accounting, if a company so elects. The adoption of this standard is not expected to have a material impact on the Operating Partnership's results of operations, financial position or liquidity.

In November 2002, the FASB issued FASB Interpretation No. 45 (FIN No. 45), "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others." This interpretation expands the disclosures to be made by a guarantor in its financial statements about its obligations under certain guarantees and requires the guarantor to recognize a liability for the fair value of an obligation assumed under a guarantee. FIN No. 45 clarifies the requirements of SFAS No. 5, Accounting for Contingencies, relating to guarantees. In general, FIN No. 45 applies to contracts or indemnification agreements that contingently require the guarantor to make payments to the guaranteed party based on changes in an underlying that is related to an asset, liability, or equity security of the guaranteed party. The disclosure requirements of FIN No. 45 are effective to the Operating Partnership as of December 31, 2002, and require disclosure of the nature of the guarantee, the maximum potential amount of future payments that the guarantor could be required to make under the guarantee, and the current amount of the liability, if any, for the guarantor's obligations under the guarantee. The recognition requirements of FIN No. 45 are to be applied prospectively to guarantees issued or modified after December 31, 2002. The Operating Partnership does not expect the requirements of FIN No. 45 to have a material impact on results of operations, financial position or liquidity.

In January 2003, the FASB issued FASB Interpretation No. 46 (FIN No. 46), "Consolidation of Variable Interest Entities." The objective of this interpretation is to provide guidance on how to identify a variable interest entity ("VIE") and determine when the assets, liabilities, non-controlling interests, and results of operations of a VIE need to be included in a company's consolidated financial statements. A company that holds variable interests in an entity will need to consolidate the entity if the company's interest in the VIE is such that the company will

F-54


absorb a majority of the VIE's expected losses and/or receive a majority of the entity's expected residual returns, if they occur. FIN No. 46 also requires additional disclosures by primary beneficiaries and other significant variable interest holders. The provisions of this interpretation became effective upon issuance. The Operating Partnership does not believe the adoption of this interpretation will have a material impact on results of operations, financial position or liquidity.

25.    Related Party Transactions

The Company paid a printing company affiliated with Mr. Mortimer B. Zuckerman, Chairman of the Company's Board of Directors, approximately $76,000, $73,000 and $86,000 during the years ended December 31, 2002, 2001 and 2000, respectively, for printing services principally relating to the printing of the Company's annual report to shareholders. The selection of this company as the printer for Company's annual report to shareholders was made through a bidding process open to multiple printing companies.

The Operating Partnership paid aggregate leasing commissions of approximately $591,000, $571,000 and $734,000 during the years ended December 31, 2002, 2001 and 2000, respectively, to a firm controlled by Mr. Raymond A. Ritchey's brother. Mr. Ritchey is an Executive Vice President of the Operating Partnership. Substantially all of these payments were made by two joint ventures in which the Operating Partnership had a 50% interest. The terms of the related agreement are at least as favorable to the Operating Partnership as arrangements with other brokers in comparable markets.

Mr. Martin Turchin, a director of the Company, is a non-executive/non-director Vice Chairman of Insignia. Through an arrangement with Insignia that has been in place since 1985, Turchin & Associates, an affiliate of Mr. Turchin, participates in brokerage activities for which Insignia is retained as leasing agent, some of which involve leases for space within buildings owned by the Operating Partnership. For the years ended December 31, 2002, 2001, and 2000, Turchin & Associates has advised the Operating Partnership that it has received approximately $116,000, $943,000 and $437,000, respectively, from Insignia attributable to properties owned by the Operating Partnership. Of this amount, $0.7 million is in conjunction with funds that the Operating Partnership owed to Insignia related to the acquisition of 280 Park Avenue. The total amount that was paid to Turchin & Associates, excluding amounts paid related to obligations assumed in connection with the acquisition of 280 Park Avenue, represents approximately 4.83% of the total amount paid to Insignia by the Operating Partnership since the date Mr. Turchin became a director of the Company in 1997. Pursuant to its arrangement with Insignia, Turchin & Associates has confirmed to the Operating Partnership that it is paid on the same basis with respect to properties owned by the Operating Partnership as it is with respect to properties owned by other clients of Insignia. Mr. Turchin does not participate in any discussions or other activities relating to the Operating Partnership's contractual arrangements

F-55


with Insignia either in his capacity as a member of the Company's Board of Directors or as a Vice Chairman of Insignia.

26.    Subsequent Events

On January 17, 2003, the Operating Partnership closed an unregistered offering of an additional $175.0 million in aggregate principal amount of its 6.25% senior unsecured notes due 2013. The notes were priced at 99.763% of their face amount to yield 6.28%. The Operating Partnership used the net proceeds to repay the remaining balance of its unsecured bridge loan totaling approximately $105.7 million and to repay certain construction loans maturing in 2003 totaling approximately $60.0 million.

On January 17, 2003, the Operating Partnership extended its $605.0 million Unsecured Line of Credit for a three year term expiring on January 17, 2006 with a provision for a one year extension. The interest rate on borrowings has been reduced from Eurodollar + 1.45% to Eurodollar + 0.70%, subject to adjustment in the event of a change in the Operating Partnership's unsecured debt ratings.

On January 28, 2003, the Operating Partnership closed on the sale of the Candler Building, a Class A office property totaling approximately 541,000 square feet in Baltimore, Maryland for $63.1 million. The Operating Partnership used the net proceeds to repay certain construction loans totaling approximately $60.9 million.

On February 4, 2003, the Operating Partnership closed on the sale of 875 Third Avenue, a Class A office property totaling approximately 711,901 square feet in Midtown Manhattan, for $370.1 million. The Operating Partnership used the net proceeds to repay the mortgage debt on the property totaling $146.9 million and to repay the construction loan on the Operating Partnership's 111 Huntington Avenue property totaling $203.0 million.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Partners of
Boston Properties Limited Partnership:

We have audited the accompanying combined statement of revenue over certain operating expenses (the "Statement") of 399 Park Avenue (the "Property") for the year ended December 31, 2001. This Statement is the responsibility of the Property's management. Our responsibility is to express an opinion on this Statement based on our audit.

We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the Statement is free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the Statement. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the Statement. We believe that our audit provides a reasonable basis for our opinion.

The accompanying Statement was prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission as described in Note 2 and is not intended to be a complete presentation of the Property's revenue and expenses.

In our opinion, the Statement referred to above presents fairly, in all material respects, the revenue over certain operating expenses (as described in Note 2), of the Property for the year ended December 31, 2001, in conformity with accounting principles generally accepted in the United States of America.

NOTES TO THE COMBINED STATEMENTS OF REVENUE OVER CERTAIN OPERATING EXPENSES

1.    Description of the Property

The accompanying combined statements of revenue over certain operating expenses (the "Statements") includes the operations of an approximately 1.7 million square foot Class A office tower known as 399 Park Avenue (the "Property"), which was operated as two separate condominium units, located in New York City, New York. On September 25, 2002, the Property was acquired by Boston Properties, Inc. (the "Company") through its subsidiary Boston Properties Limited Partnership from Citibank, N.A ("Citibank"). Citibank occupies approximately 696,000 square feet of space at the Property at September 30, 2002.

Total consideration for the acquisition was approximately $1.06 billion, which was financed with a $1.0 billion unsecured bridge loan, and the balance with cash.

2.    Basis of Accounting

The accompanying Statement has been prepared on the accrual basis of accounting but is not representative of the actual operations of the Property for the periods shown. The Statement has been prepared in accordance with Rule 3-14 of Regulation S-X of the Securities and Exchange Commission for real estate properties acquired or to be acquired. Accordingly, this Statement excludes revenue attributable to the Citibank owner-occupied space in condominium unit two and certain historical expenses not comparable to the operations of the Property after acquisition such as certain ancillary income, amortization, depreciation, interest, certain owner occupant expenses, corporate expenses and certain other costs not directly related to the future operations of the Property.

3.    Significant Accounting Policies

Rental Revenue

Rental revenue is recognized on a straight-line basis over the terms of the related leases. The excess of recognized rentals over amounts due pursuant to lease terms is recorded as accrued rent. The impact of the straight-line rent adjustment increased revenue by approximately $64,000 and $4,585,000 for the year ended December 31, 2001 and for the period from January 1, 2002 through September 24, 2002 (unaudited), respectively.

Unaudited Interim Information

The Statement for the period from January 1, 2002 through September 24, 2002 is unaudited. In the opinion of management, all adjustments necessary for a fair presentation of such Statement (in accordance with the Basis of Accounting as described in Note 2) have been included. The results of operations for the period are not necessarily indicative of the Property's future results of operations.

F-69

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

4.    Description of Leasing Arrangements

The office and retail space is leased to tenants under leases with terms that vary in length. Certain leases contain reimbursement clauses and renewal options. Minimum lease payments due under noncancelable operating leases in effect as of September 25, 2002 (unaudited), for the remainder of 2002 and annually thereafter are as follows:

(in thousands)

   Amount(1)
2002 (9/25/02—12/31/02)   $ 27,040
2003     110,804
2004     111,070
2005     110,700
2006     105,839
2007     100,820
Thereafter     966,544
(1)
Includes the addition of minimum lease payments that Citibank will owe under terms of the lease agreement signed concurrent with the Company's acquisition of the Property.
