                          (UNAUDITED AND IN THOUSANDS)

1.  ORGANIZATION

    Boston Properties, Inc. (the "Company"), a Delaware corporation, is a
self-administered and self-managed real estate investment trust ("REIT"). The
Company is the sole general partner of Boston Properties Limited Partnership
(the "Operating Partnership") and at March 31, 2000, owned an approximate 67%
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 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, except that, the Company
may, at its election, in lieu of a cash redemption, acquire such OP Unit for one
share of common stock of the Company ("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 bear 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.

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

    To assist the Company in maintaining its status as a REIT, the Company
leases its three in-service hotel properties, pursuant to a lease 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, respectively, are the sole member-managers.
Messrs. Zuckerman and Linde have a 9.8% economic interest in such lessee and one
or more unaffiliated public charities have a 90.2% economic interest. Marriott
International, Inc. manages these hotel properties under the
Marriott-Registered Trademark- name pursuant to a management agreement with the
lessee. Under the REIT requirements, revenues from a hotel are not considered to
be rental income for purposes of certain income tests that a REIT must meet.
Accordingly, in order to maintain its qualification as a REIT, the Company has
entered into the participating leases described above to provide revenue that
qualifies as rental income under the REIT requirements.

    As of March 31, 2000, the Company and the Operating Partnership had
67,954,225 and 24,385,628 shares of Common Stock and OP Units outstanding,
respectively. In addition, the Company had 2,000,000 shares of Preferred Stock
and the Operating Partnership had 8,713,131 Preferred Units outstanding.

1.  ORGANIZATION (CONTINUED)
    THE PROPERTIES:

    As of March 31, 2000, the Company owns a portfolio of 139 commercial real
estate properties (136 and 124 properties at December 31, 1999 and March 31,
1999, respectively) (the "Properties") aggregating over 36.0 million square
feet. The properties consist of 126 office properties with approximately
28.4 million net rentable square feet (including 12 properties under development
expected to contain approximately 3.6 million net rentable square feet) and
approximately 5.5 million additional square feet of structured parking for
15,556 vehicles, nine industrial properties with approximately 0.9 million net
rentable square feet, three hotels with a total of 1,054 rooms (consisting of
approximately 0.9 million square feet), and a parking garage with 1,170 spaces
(consisting of approximately 0.3 million square feet). In addition, the Company
owns, has under contract, or has an option to acquire 49 parcels of land
totaling approximately 510.3 acres, which will support approximately
10.5 million square feet of development.

2.  BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    The consolidated financial statements of the Company include all the
accounts of the Company, its majority-owned Operating Partnership and
subsidiaries. The financial statements reflect the properties acquired at their
historical basis of accounting to the extent of the acquisition of interests
from the predecessor's owners who continued as investors. The remaining
interests acquired for cash from those owners of the predecessor who decided to
sell their interests have been accounted for as a purchase and the excess of the
purchase price over the related historical cost basis was allocated to real
estate. All significant intercompany balances and transactions have been
eliminated. These financial statements should be read in conjunction with the
Company's financial statements and notes thereto contained in the Company's
annual report on Form 10-K for its fiscal year ended December 31, 1999.

    The accompanying interim financial statements are unaudited; however, the
financial statements have been prepared in accordance with accounting principles
generally accepted in the United States for interim financial information and in
conjunction with the rules and regulations of the Securities and Exchange
Commission. Accordingly, they do not include all of the disclosures required by
accounting principles generally accepted in the United States for complete
financial statements. In the opinion of management, all adjustments (consisting
solely of normal recurring matters) necessary for a fair presentation of the
financial statements for these interim periods have been included. The results
of operations for the interim periods are not necessarily indicative of the
results to be obtained for other interim periods or for the full fiscal year.

    Certain prior-year balances have been reclassified in order to conform to
the current-year presentation.

3.  REAL ESTATE ACQUIRED DURING THE QUARTER ENDED MARCH 31, 2000

    On January 12, 2000, the Company acquired its joint venture partner's 75%
interest in One and Two Reston Overlook, an unconsolidated joint venture, for
cash of approximately $15.2 million. The acquisition was accounted for using the
purchase method of accounting and is now consolidated with the Company.

3.  REAL ESTATE ACQUIRED DURING THE QUARTER ENDED MARCH 31, 2000 (CONTINUED)
    On March 1, 2000, the Company acquired three Class A office buildings
totaling approximately 408,163 square feet at Carnegie Center in Princeton, New
Jersey, under terms of the original Carnegie Center contribution agreement dated
June 30, 1998. The properties are located within the existing Carnegie Center
Portfolio. The properties were acquired from a related party for approximately
$66.5 million, which was funded through the assumption of debt of approximately
$49.0 million at a rate of 7.39% and the issuance of 577,817 common units of
partnership interest in the operating partnership valued at approximately
$17.5 million. The acquisition was approved by a vote of the independent
directors of the Company.

    On March 23, 2000, the Company acquired an 8.9-acre site in Herndon,
Virginia for approximately $3.2 million. The site will support approximately
135,000 square feet of development.

4.  INVESTMENTS IN UNCONSOLIDATED JOINT VENTURES

    The investments in unconsolidated joint ventures represent (i) a 25%
interest in a joint venture that owns and operates an office building in Reston,
Virginia and (ii) a 50% interest in a joint venture which owns and operates an
office building and a residential apartment building in Washington, D.C. Under
the equity method of accounting, the net equity investment is reflected on the
consolidated balance sheets.

    The combined summarized balance sheets of the joint ventures are as follows:

11.  SEGMENT INFORMATION

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

    Asset information by segment is not reported, since the Company does not use
this measure to assess performance: therefore, the depreciation and amortization
expenses are not allocated among segments. Interest income, management and
development services, interest expense and general and administrative expenses
are not included in net operating income, as the internal reporting addresses
these on a corporate level.

ITEM 2--MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
  OF OPERATIONS

    The following discussion should be read in conjunction with the financial
statements and notes thereto appearing elsewhere in this report. This Report on
Form 10-Q contains forward-looking statements within the meaning of Section 27A
of the Securities Act of 1933, as amended, and Section 21E of the Securities
Exchange Act of 1934, as amended. Actual results or developments could differ
materially from those projected in such statements as a result of certain
factors set forth in the section below entitled "Certain Factors Affecting
Future Operating Results" and elsewhere in this report.

    Since January 1, 1999, the Company has increased its in-service portfolio
from 110 properties to 127 properties (the "Total Portfolio"). As a result of
the growth in the Company's Total Portfolio, the financial data presented below
shows significant changes in revenues and expenses from period to period. The
Company does not believe that its period-to-period financial data are
comparable. Therefore, the comparison of operating results for the three months
ended March 31, 2000 and 1999 show separately changes attributable to the
properties that were owned by the Company for all of each period compared (the
"Same Property Portfolio") and the changes attributable to the Total Portfolio.

RESULTS OF OPERATIONS
COMPARISON OF THE THREE MONTHS ENDED MARCH 31, 2000 TO THE THREE MONTHS ENDED
MARCH 31, 1999.

    The table below reflects selected operating information for the Same
Property Portfolio and the Total Portfolio. The Same Property Portfolio consists
of the 110 properties acquired or placed in service on or prior to January 1,
1999.

                            BOSTON PROPERTIES, INC.

    The increase in rental revenues in the Same Property Portfolio is primarily
a result of an overall increase in rental rates on new leases and rollovers and
a small increase in occupancy, offset by a decrease in lease termination fees
from $1.2 million to $0.1 million. The increase in rental revenues for the Total
Portfolio is primarily a result of the properties acquired or placed-in-service
after January 1, 1999.

    The decrease in development and management services revenue is due to a
non-recurring development fee of approximately $0.9 million earned during the
three months ended March 31, 1999.

    The decrease in interest and other revenue is primarily due to interest
income earned on $420.1 million of notes receivable related to the Embarcadero
Center acquisition during the three months ended March 31, 1999.

    Property operating expenses (real estate taxes, utilities, repairs and
maintenance, cleaning and other property related expenses) in the Same Property
Portfolio increased mainly due to an increase in real estate taxes. Property
operating expenses for the Total Portfolio increased mainly due to the
properties acquired or placed-in-service after January 1, 1999.

    General and administrative expenses increased due to the increase in the
overall size of the Total Portfolio since January 1, 1999. The Company has hired
additional employees as a result of the new acquisitions.

    Interest expense increased due to new and assumed mortgage indebtedness and
the use of the Company's unsecured revolving line of credit (the "Unsecured Line
of Credit").

    Depreciation and amortization expense for the Same Property Portfolio
increased as a result of capital and tenant improvements made since March 31,
1999. Depreciation and amortization expense for the Total Portfolio increased
mainly due to the properties acquired or placed-in-service after January 1,
1999.

LIQUIDITY AND CAPITAL RESOURCES

    The Company's consolidated indebtedness at March 31, 2000 was approximately
$3.5 billion and bore interest at a weighted average interest rate of
approximately 7.09% per annum. Based on the Company's total market
capitalization at March 31, 2000 of approximately $6.9 billion, the Company's
consolidated debt represents 51.3% of its total market capitalization.

    The Company has a $500 million unsecured revolving line of credit (the
"Unsecured Line of Credit"). The Company uses the Unsecured Line of Credit
principally to facilitate its development and acquisition activities and for
working capital purposes. As of May 10, 2000, the Company had $296.0 million
outstanding under the Unsecured Line of Credit.

    The Company expects to meet its short-term liquidity requirements generally
through its existing working capital and net cash provided by operations. The
Company's operating properties and hotels require periodic investments of
capital for tenant-related capital expenditures and for general capital
improvements. For the three months ended March 31, 2000, the Company's recurring
capital expenditures totaled $2.0 million.

    The Company expects to meet its long-term requirements for the funding of
property development, property acquisitions and other non-recurring capital
improvements through long-term secured and unsecured indebtedness (including the
Unsecured Line of Credit) and the issuance of additional equity securities of
the Company.

    The Company has development projects currently in process, which require
commitments to fund to completion. Commitments under these arrangements totaled
approximately $680.0 million as of March 31, 2000. The Company expects to fund
these commitments using available cash, construction loans and the Unsecured
Line of Credit. In addition, the Company has options to acquire land that
require minimum deposits that the Company will fund using available cash or the
Unsecured Line of Credit.

FUNDS FROM OPERATIONS

    Management believes that Funds from Operations is helpful to investors as a
measure of the performance of an equity REIT because, along with cash flows from
operating activities, financing activities and investing activities, it provides
investors with an understanding of the ability of the Company to incur and
service debt and make capital expenditures. The Company computes Funds from

                                       16

                            BOSTON PROPERTIES, INC.

Operations in accordance with standards established by the White Paper on Funds
from Operations approved by the Board of Governors of NAREIT in 1995 and
clarified in 1999, which may differ from the methodology for calculating Funds
from Operations utilized by other equity REITs, and accordingly, may not be
comparable to such other REITs. The White Paper defines Funds from Operations as
net income (loss) (computed in accordance with accounting principles generally
accepted in The United States, "GAAP"), excluding gains (or losses) from sales
of property, plus real estate related depreciation and amortization and after
adjustments for unconsolidated partnerships and joint ventures. Effective
January 1, 2000, the calculation of FFO includes non-recurring events, except
for those that are defined as "extraordinary items" under GAAP and gains and
losses from sales of depreciable operating property. The revised definition of
FFO did not have a material impact on the Company's calculation. Funds from
Operations does not represent amounts available for management's discretionary
use because of needed capital replacement or expansion, debt service
obligations, or other commitments and uncertainties. Funds from Operations
should not be considered as an alternative to net income (determined in
accordance with GAAP) as an indication of the Company's financial performance or
to cash flows from operating activities (determined in accordance with GAAP) as
a measure of the Company's liquidity, nor is it indicative of funds available to
fund the Company's cash needs, including its ability to make distributions. The
Company believes that in order to facilitate a clear understanding of the
historical operating results of the Company, Funds from Operations should be
examined in conjunction with net income as presented in the consolidated
financial statements.

    The following table presents the Company's Funds from Operations for the
three months ended March 31, 2000 and 1999:

CERTAIN FACTORS AFFECTING FUTURE OPERATING RESULTS

    This Report on Form 10-Q contains forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended, regarding the
Company's business, strategies, revenues, expenditures and operating and capital
requirements. The following factors, among others, could cause actual results,
performance or achievements of the Company to differ materially from those set
forth or contemplated in the forward-looking statements made in this report:
general risks affecting the real estate industry (including, without limitation,
the inability to enter into or renew leases, dependence on tenants' financial
condition, and competition from other developers, owners and operators of real
estate); risks associated with the availability and terms of financing and the
use of debt to fund acquisitions and developments; failure to manage effectively
the Company's growth and expansion into new markets or to integrate acquisitions
successfully; risks and uncertainties affecting property development and
construction (including, without limitation, construction delays, cost overruns,
inability to obtain necessary permits and public opposition to such activities);
risks associated with downturns in the national and local economies, increases
in interest rates, and volatility in the securities markets; costs of compliance
with the Americans with Disabilities Act and other similar laws; potential
liability for uninsured losses and environmental contamination; risks associated
with the Company's potential failure to qualify as a REIT under the Internal
Revenue Code of 1986, as amended, and possible adverse changes in tax and
environmental laws; and risks associated with the Company's dependence on key
personnel whose continued service is not guaranteed.

INFLATION

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

ITEM 3--QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

    Market risk is the risk of loss from adverse changes in market prices and
interest rates. The primary market risk facing the Company is mortgage debt,
which bears interest primarily at fixed rates, and therefore, the fair value of
these instruments is affected by changes in the market interest rates. The
following table presents principal cash flows (in thousands) based upon maturity
dates of the debt obligations and the related weighted average interest rates by
expected maturity dates for the fixed rate debt. The interest rate of the
variable rate debt as of March 31, 2000 ranged from LIBOR plus 1.00% to LIBOR
plus 2.00%. During January 2000, the Company entered into three interest rate
hedge agreements totaling $450.0 million. The agreements provide for a fixed
interest rate when LIBOR floats between 0% and 5.80% or 5.00% to 5.60% and when
LIBOR ranges from 6.35% to 7.95% for terms ranging from three to five years, per
the individual agreements.
