PART I

Item 1. Business

General

As used herein, the terms "we," "us," "our" or the "Company" refer to
Boston Properties, Inc., a Delaware corporation organized in 1997, individually
or together with its subsidiaries, including Boston Properties Limited
Partnership, a Delaware limited partnership, and our predecessors. We are 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. Our properties are concentrated in four core markets -
Boston, Washington, D.C., midtown Manhattan and San Francisco. We conduct
substantially all our business through Boston Properties Limited Partnership. At
December 31, 2000 we owned 145 properties, totaling 37.9 million net rentable
square feet. Our properties consisted of 134 office properties, comprised of 103
Class A office buildings and 31 properties that support both office and
technical uses, including 15 properties under construction, eight industrial
properties and three hotels. 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.

We have a $605 million unsecured revolving line of credit with Fleet
National Bank, as agent, which expires in March 2003. As of March 14, 2001, zero
was outstanding under our unsecured revolving line of credit. You should refer
to "Item 7. Management's Discussion and Analysis of Financial Condition and
Results of Operations - Liquidity and Capital Resources" for additional
information regarding our unsecured revolving line of credit and our other
indebtedness.

We are a full service real estate company, with substantial in-house
expertise and resources in acquisitions, development, financing, construction
management, property management, marketing, leasing, accounting, tax and legal
services. As of December 31, 2000, we had over 600 employees. Our 25 senior
officers, together with Mr. Mortimer Zuckerman, Chairman of our board of
directors, have an average of 24 years experience in the real estate industry
and an average of 14 years tenure with us. Our principal executive office is
located at 800 Boylston Street, Boston, Massachusetts 02199 and its telephone
number 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 502
Carnegie Center, Princeton, New Jersey 08540.

Boston Properties Limited Partnership

Boston Properties Limited Partnership, a Delaware limited partnership, is
the entity through which we conduct substantially all of our business and own
(either directly or through subsidiaries) substantially all of our assets. We
are the sole general partner and, as of March 14,


1
2001, the owner of approximately 74.3% of the economic interests in Boston
Properties Limited Partnership. This structure is commonly referred to as an
umbrella partnership REIT or "UPREIT". Our general and limited partnership
interests in Boston Properties Limited Partnership entitle us to share in cash
distributions from, and in the profits and losses of, Boston Properties Limited
Partnership in proportion to our percentage interest therein and entitle us to
vote on all matters requiring a vote of the limited partners. The other partners
of Boston Properties Limited Partnership are persons who contributed their
direct or indirect interests in certain properties to Boston Properties Limited
Partnership in exchange for common units of limited partnership interest in
Boston Properties Limited Partnership or preferred units of limited partnership
interest in Boston Properties Limited Partnership. Pursuant to the limited
partnership agreement of Boston Properties Limited Partnership, as amended,
unitholders may tender their common units of Boston Properties Limited
Partnership for cash equal to the value of an equivalent number of shares of our
common stock. In lieu of delivering cash, however, we may, at our option, choose
to acquire any units so tendered by issuing common stock in exchange for the
units. Our common stock will be exchanged for units on a one-for-one basis. This
one-for- one exchange ratio may be adjusted to prevent dilution. We currently
anticipate that we will elect to issue our common stock in connection with each
such presentation for redemption rather than having Boston Properties Limited
Partnership pay cash. With each such exchange or redemption, our percentage
ownership in Boston Properties Limited Partnership will increase. In addition,
whenever we issue shares of our common stock other than to acquire common units
of Boston Properties Limited Partnership, we must contribute any net proceeds we
receive to Boston Properties Limited Partnership and Boston Properties Limited
Partnership must issue to us an equivalent number of common units of Boston
Properties Limited Partnership.

Preferred units of Boston Properties Limited Partnership have the rights,
preferences and other privileges (including the right to convert into common
units of Boston Properties Limited Partnership) as are set forth in amendments
to the limited partnership agreement of Boston Properties Limited Partnership.
Boston Properties Limited Partnership currently has four series of its preferred
units (excluding preferred units held by Boston Properties, Inc.). The Series
One preferred units have an aggregate liquidation preference of approximately
$85 million and bear 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 also
have the right to convert into common units of Boston Properties Limited
Partnership all or part of the Series One units on or after June 3, 2003, if our
common stock at the time of our election is trading at a price of at least
$42.08 per share.

The Series Two and Series Three preferred units, which together have an
aggregate liquidation preference of approximately $311 million, have, between
each other, similar economic terms. On and after December 31, 2002, the Series
Two and Series Three units will be convertible, at the holder's election, into
common units at a conversion price of $38.10 per common unit. Distributions on
the Series Two and Series Three units are payable quarterly and generally accrue
at rates of: 5.0% per annum through March 31, 1999; 5.5% through December 31,
1999; 5.625% through December 2000; 6.0% through December 31, 2001; 6.5% through
December 31, 2002; 7.0% until May 12, 2009; and 6.0% thereafter. The terms of
the Series Two and Series Three units provide that they may be redeemed for cash
in six annual tranches,


2
beginning on May 12, 2009, at the election of us or the holders. We also have
the right to convert into common units of Boston Properties Limited Partnership
any Series Two and Series Three units that are not redeemed when they are
entitled to redemption.

The Series Z preferred units have an aggregate liquidation preference of
the greater of the value of our common stock or $37.25 per unit. The Series Z
preferred units are not entitled to receive any distributions until after August
11, 2001. From August 11, 2001 until February 11, 2002, each Series Z preferred
unit entitles its holder to receive one-half of any distributions paid on a
common unit. After February 11, 2002, to the extent that any Series Z preferred
units are still outstanding, each Series Z preferred unit entitles its holder to
receive an amount equal to 100% of any distributions paid on a common unit. The
Series Z preferred units will automatically convert into common units on
February 11, 2002 or, if later, the date on which we register with the
Securities and Exchange Commission the shares of our common stock issuable in
exchange for the common units into which the Series Z units are convertible.

Real Estate Acquisitions during 2000

On January 12, 2000, we acquired our joint venture partner's 75% interest
in One and Two Reston Overlook, an unconsolidated joint venture, for cash of
approximately $15.2 million and the assumption of approximately $69.0 million in
debt.

On March 1, 2000, we acquired three Class A office buildings totaling
approximately 408,163 square feet at Carnegie Center in Princeton, New Jersey,
under the terms of the original Carnegie Center Portfolio acquisition. 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 Boston Properties Limited Partnership valued at approximately $17.5
million. The acquisition was approved by a vote of our independent directors.

On August 22, 2000, we acquired the remaining 50% interest in the
development rights at the Prudential Center in Boston, Massachusetts for
approximately $18.2 million, which was funded through the issuance of 439,059
shares of our common stock.

On December 1, 2000, we acquired the leasehold interest and ground rent
credits at the site of the future Times Square Tower in midtown Manhattan, for
approximately $165.1 million in cash. This development will consist of a 47-
floor, 1.2 million square foot office tower.

Developments Placed in Service during 2000

In the second quarter of 2000, the Orbital Sciences project was
placed-in-service. This project consists of two Class A office buildings
totaling approximately 174,832 square feet and is located in Dulles, VA. We
developed this project, in which we have a 100% interest, at a total cost to us
of approximately $30.5 million.

In the fourth quarter of 2000, the 140 Kendrick Street project was
placed-in-service. This


3
project consists of three Class A office buildings totaling approximately
381,000 square feet and is located in Needham, Massachusetts. We developed the
project, in which we have a 25% interest, at a total cost to us of approximately
$18.8 million.

In the fourth quarter of 2000, the Market Square North project was
placed-in-service. This project consists of a Class A office building totaling
approximately 401,255 square feet and is located in Washington, D.C. We
developed the project, in which we have a 50% interest, at a total cost to us of
approximately $59.2 million.

New Joint Venture with Financial Partner during 2000

On May 12, 2000, we entered into a joint venture with the New York State
Common Retirement Fund. The initial term of the joint venture agreement runs for
three years or until the New York State Common Retirement Fund's equity
commitment of $270 million is met, although it has the right to increase its
financial commitment prior to the end of the third year. During the term of the
joint venture agreement, New York State Common Retirement Fund has the right to
participate in our acquisition opportunities and development projects that we
pursue with an institutional partner. We will manage the development and
operation of all joint venture properties.

On May 12, 2000, pursuant to the joint venture agreement, the New York
State Common Retirement Fund acquired partial interests in two properties that
we previously owned in their entirety. We retained a 51% interest in the first
property, Metropolitan Square, a 582,194-square foot office property in
Washington, D.C. and a 25% interest in the second property, 140 Kendrick Street,
a 381,000-square foot build-to-suit development property in Needham,
Massachusetts. The interests in the properties were acquired for cash of
approximately $46.7 million and the assumption of debt of approximately $88.2
million and resulted in a gain to us of $0.4 million.

On September 13, 2000, we acquired a 35% interest in 265 Franklin Street,
a 325,699 square foot office property in Boston, Massachusetts through our joint
venture with the New York State Common Retirement Fund, which acquired 65% of
this property. Our interest in this property was acquired with cash and new debt
financing totaling approximately $34.3 million.

On December 8, 2000, we agreed with the New York State Common Retirement
Fund to develop 901 New York Avenue, a Class A office building in Washington,
D.C. totaling 550,000 square feet. We have a 25% interest and manage the
development of the property, while the New York State Common Retirement Fund
owns a 75% interest.

Equity Financing Activities during 2000

On August 22, 2000, we issued 439,059 shares of common stock, valued at
approximately $18.2 million, in connection with the acquisition of the remaining
50% interest in the development rights at the Prudential Center in Boston,
Massachusetts.


4
On October 31, 2000, we completed a public offering of 17,110,000 shares
of our common stock at a price per share of $39.0625 (including 2,110,000 shares
issued as a result of the exercise of an overallotment option by the
underwriters) resulting in net proceeds to us of approximately $633.8 million.

Business and Growth Strategies

Business Strategy

Our primary business objective is to maximize return on investment so as
to provide our stockholders with the greatest possible total return. Our
strategy to achieve this objective is:

o to concentrate on a few carefully selected markets and to be one of,
if not the leading, owner and developer in each of those markets. We
select markets and submarkets where tenants have demonstrated a
preference for high quality office buildings and other facilities.
o to emphasize markets and submarkets within those markets where there
are barriers to the creation of new supply and where skill,
financial strength and diligence are required to successfully
develop and manage high quality office, research and development
and/or industrial space.
o to take on complex, technically challenging projects, leveraging the
skills of our management team to successfully develop, acquire or
reposition properties which other organizations may not have the
capacity or resources to pursue.
o to concentrate on high quality, state-of-the-art real estate
designed to meet the demands of today's knowledge-based tenants and
to manage those facilities so as to become the landlord of choice
for both existing and prospective clients.
o to opportunistically acquire assets which increase our penetration
in the markets in which we have chosen to concentrate and which
exhibit an opportunity to improve returns through repositioning,
changes in management focus and re-leasing as existing leases
terminate.


5
Growth Strategies

External Growth

We believe that we are well positioned to realize significant growth
through external asset development and acquisition. 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:

o the significant increase in demand for new, high quality office
space in our core markets;
o our control of sites (including sites under contract or option to
acquire) in our core markets that will support approximately 10.6
million square feet of new office development;
o our reputation gained through the stability and strength of our
existing portfolio of properties;
o our relationships with leading national corporations and public
institutions seeking new facilities and development services;
o our relationships with nationally recognized financial institutions
that provide capital to the real estate industry; and
o the substantial amount of commercial real estate owned by domestic
and foreign institutions, private investors, and corporations who
are seeking to sell these assets in our market areas.

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

o Pursue development in selected submarkets. We believe that
development of well-positioned office buildings is and will continue
to be justified in many of our submarkets. We believe in acquiring
land in response to market conditions that allow for its development
in the relative near term. While we purposely concentrate in markets
with high barriers to entry, we have demonstrated over our 30 year
history an ability to make carefully timed land acquisitions in
submarkets where we can become one of the market leaders in
establishing rent and other business terms. We believe that there
are opportunities in our existing and other markets for a well
capitalized developer to acquire land with development potential at
key locations.

In the past, we have been particularly successful at acquiring
sites or options to purchase sites that need governmental approvals.
Because of our development expertise, knowledge of the governmental
approval process and reputation for quality development with local
government approval regulatory bodies, we generally have been able
to secure the permits necessary to allow development, and profit
from the


6
resulting increase in land value. We seek out complex projects where
we can add value through the efforts of our experienced and skilled
management team leading to significantly enhanced returns on
investment.

o Acquire assets and portfolios of assets from institutions or
individuals. We believe that due to our size, management strength
and reputation, we are in an advantageous position to acquire
portfolios of assets or individual properties from institutions or
individuals. We may acquire properties for cash, but we believe that
we are particularly well positioned to appeal to sellers wishing to
convert on a tax-deferred basis their ownership of property to the
ownership of equity in a diversified real estate operating company
that offers liquidity through access to the public equity markets.
In addition, we may pursue mergers with and acquisitions of
compatible real estate firms. Our ability to offer units in Boston
Properties Limited Partnership to sellers who would otherwise
recognize a gain upon a sale of assets for cash or our common stock
may facilitate this type of transaction on a tax-efficient basis.

o Acquire existing underperforming assets and portfolios of assets. We
continue to actively pursue opportunities to acquire existing
buildings that, while currently generating income, are either
underperforming the market due to poor management or are currently
leased at below market rents with anticipated roll-over of space.
These opportunities may include the acquisition of entire portfolios
of properties. We believe that because of our in-depth market
knowledge and development experience in each of our markets, our
national reputation with brokers, financial institutions and others
involved in the real estate market and our access to
competitively-priced capital, we are well-positioned to identify and
acquire existing, underperforming properties for competitive prices
and to add significant additional value to such properties through
our effective marketing strategies and responsive property
management program.

Internal Growth

We believe that significant opportunities exist to increase cash flow from
our existing properties because they are of high quality and in desirable
locations in markets that, in general, are experiencing rising rents, low
vacancy rates and increasing demand for office and industrial space. In
addition, our properties are in markets where, in general, supply is limited by
the lack of available sites and the difficulty of receiving the necessary
approvals for development on vacant land. 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 design and
construction of tenant improvements. In addition, we believe that our hotel
properties will add to our internal growth because of their desirable locations
in the downtown Boston and East Cambridge submarkets, which are experiencing
high occupancy rates and continued growth in room rates. The effective
management of Marriott International, Inc., has resulted in high occupancy,
guest satisfaction and growth in room rates


7
while limiting increases in operating costs. We expect to continue our internal
growth as a result of our ability to:

o Cultivate existing submarkets. In choosing locations for our
properties, we have paid particular attention to transportation and
commuting patterns, physical environment, adjacency to established
business centers, proximity to sources of business growth and other
local factors.

Many of these submarkets are experiencing increasing rents
and, as a result, current market rates often exceed the rents being
paid by our tenants. Based on leases in place at December 31, 2000,
leases with respect to 7.27% of our office properties and 13.95% of
our industrial properties will expire in calendar year 2001. We
believe that leases expiring over the next three years in these
submarkets will be renewed, or space re-let, at higher rents than
previously in effect.

o Directly manage properties to maximize the potential for tenant
retention. We provide property management services ourselves, rather
than contracting for this service, to maintain awareness of and
responsiveness to tenant needs. We and our properties also benefit
from cost efficiencies produced by an experienced work force
attentive to preventive maintenance and energy management and from
our continuing programs to assure that our property management
personnel at all levels remain aware of their important role in
tenant relations. Our philosophy has not been to invest significant
capital in technology, but to form alliances to provide better
tenant service and realize potential incremental revenues with
little additional capital investment.

o Replace tenants quickly at best available market terms and lowest
possible transaction costs. We believe that we have a competitive
advantage in attracting new tenants and achieving rental rates at
the higher end of our markets as a result of our well located, well
designed and well maintained properties, our reputation for high
quality building services and responsiveness to tenants, and our
ability to offer expansion and relocation alternatives within our
submarkets.

The Hotel Properties

To assist in maintaining our status as a REIT, we lease our three hotel
properties to ZL Hotel LLC pursuant to a lease that entitles us to a percentage
of the gross receipts of our hotel properties. Mr. Mortimer B. Zuckerman, the
Chairman of our board of directors, and Edward H. Linde, our President and Chief
Executive Officer, are the sole member-managers of, and have a 9.8% economic
interest in, ZL Hotel LLC; two unaffiliated public charities own the remaining
90.2% economic interest. Marriott International, Inc. manages our hotel
properties under the Marriott(R) name pursuant to a management agreement with ZL
Hotel LLC. Under the REIT requirements, revenues from a hotel are not considered
to be rental income for purposes of certain income tests, which a REIT must
meet. Accordingly, in order to maintain our qualification as a REIT, we have
entered into the participating leases with ZL Hotel LLC described above to
provide revenue that qualifies as rental income under the REIT requirements.


8
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.

Seasonality

Our hotel properties traditionally have experienced significant
seasonality in their operating income, with weighted average net operating
income by quarter over the three years 1998 through 2000 as follows:

First Quarter Second Quarter Third Quarter Fourth Quarter
- ------------- -------------- ------------- --------------
14% 29% 32% 25%

Our other properties have not traditionally experienced significant
seasonality.


9
RISK FACTORS

Set forth below are the risks that we believe are material to our stockholders.
We refer to the shares of our common and preferred stock and the units of
limited partnership interest in Boston Properties Limited Partnership together
as our "securities," and the investors who own shares and/or units as our
"securityholders." This section includes or refers to certain forward-looking
statements. You should refer to the explanation of the qualifications and
limitations on such forward-looking statements beginning on page 32.

We may be unable to manage effectively our rapid growth and expansion into new
markets.

We have grown rapidly since our initial public offering in June 1997 and
have entered or significantly expanded our real estate holdings in new markets.
If we do not effectively manage our rapid growth, we may not be able to make
expected distributions to our securityholders and the value of our securities
may decline.

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 our 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 revenues generated by our office, industrial, and hotel properties:

o downturns in the national, regional and local economic climate;

o competition from other office, industrial, hotel and other
commercial buildings;

o local real estate market conditions, such as oversupply or reduction
in demand for office, industrial, hotel or other commercial space;

o changes in interest rates and availability of financing;

o vacancies or inability to rent spaces on favorable terms;

o increased operating costs, including insurance premiums, utilities,
and real estate taxes; and

o civil disturbances, earthquakes and other natural disasters or acts
of God that may result in uninsured or underinsured losses.


10
Significant expenditures associated with each investment, such as debt
service payments, real estate taxes, insurance and maintenance costs are
generally not reduced when circumstances cause a reduction in revenues from a
property.

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. A
downturn in the economies of these core markets, or the impact that a downturn
in the overall national economy may have upon these economies, could result in
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 result
from operations. Additionally, there are submarkets within our core markets that
are dependent upon a limited number of industries and a significant downturn in
one or more of these industries could also adversely affect our results from
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:

o we may be unable to proceed with the development of properties
because we cannot obtain financing with favorable terms;

o we may incur construction costs for a development project which
exceed our original estimates due to increased materials, labor or
other costs, which could make completion of the project uneconomical
because we may not be able to increase rents to compensate for the
increase in construction costs;

o we may be unable to obtain, or face delays in obtaining, required
zoning, land-use, building, occupancy, and other governmental
permits and authorizations, which could result in increased costs
and could require us to abandon our activities entirely with respect
to a project;

o we may abandon development opportunities after we begin to explore
them and as a result we may fail to recover expenses already
incurred;

o we may expend funds on and devote management's time to projects
which we do not complete;

o we may be unable to complete construction and leasing of a property
on schedule, resulting in increased debt service expense and
construction or renovation costs;


11
o     we may lease developed properties at below expected rental rates;
and

o occupancy rates and rents at newly completed properties may
fluctuate depending on a number of factors, including market and
economic conditions, and may result in our investment not being
profitable.

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

We intend to develop and acquire properties in joint ventures with other
persons or entities when circumstances warrant the use of this structure. The
use of a joint venture vehicle creates a risk of a dispute with our joint
venturer's and a risk that we will have to acquire a joint venturer's interest
in a development for a price at which or at a time when we would otherwise not
purchase such interest. Our joint venture partners may have different objectives
from us regarding the appropriate timing and pricing of any sale or refinancing
of properties.

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 term of this joint venture,
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.

We face risks associated with property acquisitions.

Since our initial public offering, we have made large acquisitions of
properties and portfolios of properties. We intend to continue to acquire
properties and portfolios of properties, including large portfolios that could
continue to significantly increase our size and alter our capital structure. Our
acquisition activities and their success may be exposed to the following risks:

o we may be unable to acquire a desired property because of
competition from other well capitalized real estate investors,
including both publicly traded real estate investment trusts and
institutional investment funds;

o even if we enter into an acquisition agreement for a property, it is
usually subject to customary conditions to closing, including
completion of due diligence investigations to our satisfaction;

o even if we are able to acquire a desired property, competition from
other real estate investors may significantly increase the purchase
price;

o we may be unable to finance acquisitions on favorable terms;


12
o     acquired properties may fail to perform as we expected in analyzing
our investments;

o our estimates of the costs of repositioning or redeveloping acquired
properties may be inaccurate;

o acquired properties may be located in new markets where we may face
risks associated with a lack of market knowledge or understanding of
the local economy, lack of business relationships in the area and
unfamiliarity with local governmental and permitting procedures; and

o we may be unable to quickly and efficiently integrate new
acquisitions, particularly acquisitions of portfolios of properties,
into our existing operations, and as a result our results of
operations and financial condition could be adversely affected.

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 upon 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:

o liabilities for clean-up of undisclosed environmental contamination;

o claims by tenants, vendors or other persons dealing with the former
owners of the properties;

o liabilities incurred in the ordinary course of business; and

o claims for indemnification by general partners, directors, officers
and others indemnified by the former owners of the properties.

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, we may not be able to relet 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. Although we have not experienced material
losses from tenant


13
bankruptcies or insolvencies in the past, 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 court might authorize the tenant
to reject and terminate its lease with us. In such case, our claim against the
bankrupt tenant for unpaid, 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 from 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 can be hard to sell, especially if local market conditions are
poor. 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
returns to our stockholders. 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 properties face significant competition.

We face significant competition from developers, owners and operators of
office, industrial and other commercial real estate. Substantially all of our
properties face competition from similar properties in the same market. Such
competition may effect 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. We lease these hotel properties to ZL Hotel
LLC, in which Mortimer B. Zuckerman, Chairman of our board of directors, and
Edward H. Linde, our President and Chief Executive Officer, are the sole
member-managers and have a 9.8% economic interest; two unaffiliated public
charities have a 90.2% economic interest in ZL Hotel LLC. Marriott
International, Inc. manages these hotel properties under the Marriott(R) name
pursuant to a management agreement with ZL Hotel LLC. ZL Hotel LLC pays us a
percentage of the gross receipts that the hotel properties receive. Because the
lease payments we receive 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
distribution to our securityholders. The following factors, among others, are
common to the hotel industry, and may reduce the receipts generated by our hotel
properties:

o our hotel properties compete for guests with other hotels, a number
of which have greater marketing and financial resources than our
hotel-operating business partners;


14
o     if there is an increase in operating costs resulting from inflation
and other factors, our hotel-operating business partners may not be
able to offset such increase by increasing room rates;

o our hotel properties are subject to the fluctuating and seasonal
demands of business travelers and tourism; and

o our hotel properties are subject to general and local economic
conditions that may affect demand for travel in general.

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 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 distribution
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 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 from operations.

Some potential losses are not covered by insurance.

We carry comprehensive liability, fire, flood, extended coverage and
rental loss insurance, as applicable, on our properties. We believe our coverage
is of the type and amount customarily obtained for or by an owner of similar
properties. We believe all of our properties are adequately insured. However,
there are certain types of losses, such as from wars or catastrophic acts of
nature, for which we cannot obtain insurance or for which we cannot obtain
insurance at a reasonable cost. In the event of an uninsured loss or a loss in
excess of our insurance limits, we could lose both the revenues generated from
the affected property and the capital we have invested in the affected property.
We would, however, remain obligated to repay any 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.

We carry earthquake insurance on our properties located in areas known to
be subject to earthquakes in an amount and subject to deductions which we
believe are commercially


15
reasonable. However, the amount of our earthquake insurance coverage may not be
sufficient to cover losses from earthquakes. 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 discounted for the
risk of loss. If we experience a loss which is uninsured or which exceeds policy
limits, we could lose the capital invested in the damaged properties as well as
the anticipated future revenue from those properties. Moreover, if the damaged
properties are subject to recourse indebtedness, we would continue to be liable
for the indebtedness, even if the properties were irreparable. Any such loss
could materially and adversely affect our business and financial condition and
results from operations.

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, regardless of our knowledge or responsibility, 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:

o as owner or operator we may have to pay for property damage and for
investigation and clean-up costs incurred in connection with the
contamination;

o the law typically imposes clean-up responsibility and liability
regardless of whether the owner or operator knew of or caused the
contamination;

o even if more than one person may be responsible for the
contamination, each person who shares legal liability under the
environmental laws may be held responsible for all of the clean-up
costs; and

o governmental entities and third parties may sue the owner or
operator of a contaminated site for damages and costs.

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.

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

o properly manage and maintain the asbestos;

o notify and train those who may come into contact with asbestos; and


16
o     undertake special precautions, including removal or other abatement,
if asbestos would be disturbed during renovation or demolition of a
building.

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 and industrial areas where
fill or current or historic industrial uses of the areas have caused site
contamination. Independent environmental consultants have conducted Phase I
environmental site assessments at all of our properties. These assessments
included, at a minimum, 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. Where appropriate, on a property-by-property basis, these
consultants have conducted 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 have been conducted, there is still the risk that:

o the environmental assessments and updates did not identify all
potential environmental liabilities;

o a prior owner created a material environmental condition that is not
known to us or the independent consultants preparing the
assessments;

o new environmental liabilities have developed since the environmental
assessments were conducted; and

o future uses or conditions such as changes in applicable
environmental laws and regulations could result in environmental
liability for us.

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 the
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.


17
Rising interest rates would increase our interest costs.

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, our ability to service debt
and our ability to make distributions to our securityholders.

We have no corporate limitation on the amount of debt we can incur.

Our management and board of directors have discretion under our
certificate of incorporation and bylaws to increase the amount of our
outstanding debt. Our decisions with regard to the incurrence and maintenance of
debt are based on available investment opportunities for which capital is
required, the cost of debt in relation to such investment opportunities, whether
secured or unsecured debt is available, the effect of additional debt on
existing financial ratios and the maturity of the proposed new debt relative to
maturities of existing debt. We could become more highly leveraged, resulting in
increased debt service costs that could adversely affect our cash flow and the
amount available for payment of dividends. If we increase our debt we may also
increase the risk we will be unable to repay our debt.

Our financial covenants could adversely affect our financial condition.

The mortgages on our properties contain customary negative 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.
In addition, our credit facilities contain certain customary restrictions,
requirements and other limitations on our ability to incur indebtedness,
including total debt to assets 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 ability to borrow under our credit facilities
is subject to compliance with our financial and other covenants. We rely on
borrowings under our credit facilities to finance acquisitions and development
activities and for working capital, and if we are unable to borrow under our
credit facilities, or to refinance existing indebtedness our financial condition
and results of operations would likely be adversely impacted. If we breach
covenants in our debt agreements, the lender can declare a default and require
us to repay the debt immediately and, if the debt is secured, can immediately
take possession of the property securing the loan. In addition, our credit
facilities are cross-defaulted to our other indebtedness, which would give the
lenders under our other credit facilities the right also to declare a default
and require immediate repayment.

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

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 our
outstanding securities. Our Debt to Market Capitalization Ratio was
approximately 38.7% as of December 31, 2000. To the extent that our board of
directors uses our Debt to Market Capitalization Ratio as a measure of


18
appropriate leverage, the total amount of our debt could increase as our common
stock price increases, even if we may not have a corresponding increase in our
ability to service or repay the debt. 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
degree of leverage could also make us more vulnerable to a downturn in business
or the economy generally. There is a risk that changes in our Debt to Market
Capitalization Ratio, which is in part a function of our stock price, or our
ratio of indebtedness to other measures of asset value used by financial
analysts may have an adverse effect on the market price of our common stock.

Further issuances of equity securities may be dilutive to current stockholders.

The interests of our existing stockholders could be diluted if additional
equity securities are issued to finance future developments and acquisitions
instead of incurring additional debt. Our ability to execute our business
strategy depends on our access to an appropriate blend of debt financing,
including unsecured lines of credit and other forms of secured and unsecured
debt, and equity financing, including common and preferred equity.

Failure to qualify as a real estate investment trust would cause us to be taxed
as a corporation, which would substantially reduce funds available for payment
of dividends.

If we fail to qualify as a real estate investment trust for federal income
tax purposes, we will be taxed as a corporation. We believe that we are
organized and qualified as a real estate investment trust, and intend to operate
in a manner that will allow us to continue to qualify as a real estate
investment trust. However, we cannot assure you that we are qualified as such,
or that we will remain qualified as such in the future. This is because
qualification as a real estate investment trust 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 real estate investment trust for
federal income tax purposes or the federal income tax consequences of such
qualification.

If we fail to qualify as a real estate investment trust we will face
serious tax consequences that will substantially reduce the funds available for
payment of dividends for each of the years involved because:

o we would not be allowed a deduction for dividends paid to
stockholders in computing our taxable income and would be subject to
federal income tax at regular corporate rates;

o we also could be subject to the federal alternative minimum tax and
possibly increased state and local taxes;


19
o     unless we are entitled to relief under statutory provisions, we
could not elect to be subject to tax as a real estate investment
trust for four taxable years following the year during which we were
disqualified; and

o all dividends will be subject to tax as ordinary income to the
extent of our current and accumulated earnings and profits.

In addition, if we fail to qualify as a real estate investment trust, we
will no longer be required to pay dividends. As a result of all these factors,
our failure to qualify as a real estate investment trust could impair our
ability to expand our business and raise capital, and would adversely affect the
value of our common stock.

In order to maintain our real estate investment trust status, we may be forced
to borrow funds on a short-term basis during unfavorable market conditions.

In order to maintain our real estate investment trust status, we may need
to borrow funds on a short-term basis to meet the real estate investment trust
distribution requirements, even if the then prevailing market conditions are not
favorable for these borrowings. To qualify as a real estate investment trust, we
generally must distribute to our stockholders at least 95% of our net taxable
income each year, excluding capital gains. In addition, we will be subject to a
4% nondeductible excise tax on the amount, if any, by which dividends paid by us
in any calendar year are less than the sum of 85% of our ordinary income, 95% of
our capital gain net income and 100% of our undistributed income from prior
years. We 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 may discourage takeover attempts beneficial to
stockholders.

Provisions in our certificate of incorporation and bylaws, our shareholder
rights agreement and the limited partnership agreement of Boston Properties
Limited Partnership, as well as provisions of the Internal Revenue Code and
Delaware corporate law, may:

o delay or prevent a change of control over us or a tender offer, even
if such action might be beneficial to our stockholders; and

o limit our stockholders' opportunity to receive a potential premium
for their shares of common stock over then-prevailing market prices.

Stock Ownership Limit

Primarily to facilitate maintenance of our qualification as a real estate
investment trust, our corporate charter 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 our equity stock. We
refer to this limitation as the "ownership limit." Our board of directors


20
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 our
status as a real estate investment trust for federal income tax purposes. In
addition, under our corporate charter each of Messrs. Zuckerman and Linde, along
with their family 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 or series of our equity common 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.

Boston Properties Limited Partnership Agreement

We have agreed in the limited partnership agreement of Boston Properties
Limited Partnership not to engage in business combinations unless limited
partners of Boston Properties Limited Partnership other than Boston Properties,
Inc. receive, or have the opportunity to receive, the same consideration for
their partnership interests as holders of our common stock in the transaction.
If these limited partners do not receive such consideration, we cannot engage in
the transaction unless 75% of these limited partners vote to approve the
transaction. In addition, we have agreed in the limited partnership agreement of
Boston Properties Limited Partnership that we will not consummate business
combinations in which we received the approval of our 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 our stockholders approve a business combination that
requires a vote of stockholders, the partnership agreement requires the
following before we can consummate the transaction:

o holders of interests in Boston Properties Limited Partnership
(including Boston Properties, Inc.) must vote on the matter;

o Boston Properties, Inc. must vote its partnership interests in the
same proportion as our stockholders voted on the transaction; and

o the result of the vote of holders of interests in Boston Properties
Limited Partnership must be such that had such vote been a vote of
stockholders, the business combination would have been approved.

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

Shareholder Rights Plan

We have adopted a shareholder rights plan. Under the terms of this plan,
we can in effect prevent a person or group from acquiring more than 15% of the
outstanding shares of our common stock, because, unless we approve of the
acquisition, after the person acquires more than 15% of our outstanding common
stock, all other stockholders will have the right to purchase


21
securities from us at a price that is less than their then fair market value,
which would substantially reduce the value and influence of the stock owned by
the acquiring person. Our board of directors can prevent the plan from operating
by approving of the transaction, which gives us significant power to approve or
disapprove of the efforts of a person or group to acquire a large interest in
us.

We may change our policies without obtaining the approval of our stockholders.

Our operating and financial policies, including our policies with respect
to acquisitions, growth, operations, indebtedness, capitalization and dividends,
are determined by our board of directors. Accordingly, as a stockholder, you
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 our board of directors, and Edward H. Linde, our
President and Chief Executive Officer. 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.

Our other executive officers who serve as managers of our offices have
strong regional 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 effect our operations because of diminished relationships with
lenders, prospective tenants and industry personnel.

Mr. Zuckerman has substantial outside business interests, including
serving as trustee for New York University, a trustee of Memorial
Sloan-Kettering Cancer Institute, a trustee of the Institute for Advanced
Studies at Princeton and a member of the Council on Foreign Relations and the
International Institute for Strategic Studies. He is also Chairman and
Editor-in-Chief of U.S. News & World Report, Chairman and Co-Publisher of the
New York Daily News and Chairman of the Board of Applied Graphics Technologies
and a member of the Board of Directors of Chase Manhattan Corporation National
Advisory Board, Loews Cineplex and WNET/Channel. Such outside business interests
could interfere with his ability to devote time to our business and affairs.
Over the last twenty years, Mr. Zuckerman has devoted a significant portion,
although not a majority, of his business time to the affairs of Boston
Properties and its predecessors. We have no assurance that he will continue to
devote any specific portion of his time to us, although at present, he has no
commitments which would prevent him from maintaining his current level of
involvement with our business.


22
Conflicts of interest exist with holders of interests in Boston Properties
Limited Partnership.

Sales of properties and repayment of related indebtedness will have
different effects on holders of interests in Boston Properties Limited
Partnership than on our stockholders.

Some holders of interests in Boston Properties Limited Partnership,
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 and our stockholders. Consequently, such
holders of interests in Boston Properties Limited Partnership may have different
objectives regarding the appropriate pricing and timing of any such sale or
repayment of debt. While we have exclusive authority under the limited
partnership agreement of Boston Properties Limited Partnership 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 described below, any such decision would require the approval of our
board of directors. As directors and executive officers, 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, or a majority, of our stockholders, including in a manner which could
prevent completion of a sale of a property or the repayment of indebtedness.

Agreement not to sell some properties.

Under the terms of the limited partnership agreement of Boston Properties
Limited Partnership, 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
interests in Boston Properties Limited Partnership. In addition, we have entered
into similar agreements with respect to other properties that we have acquired
in exchange for interests in Boston Properties Limited Partnership. There are a
total of 35 properties subject to these restrictions, and those 35 properties
are estimated to have accounted for approximately 55% of our total revenue for
the year ended December 31, 2000.

Boston Properties Limited Partnership has also entered into agreements
providing Messrs. Zuckerman and Linde and others 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.


23
Messrs. Zuckerman and Linde will continue to engage in other activities.

Messrs. Zuckerman and Linde have a broad and varied range of investment
interests. Either one could acquire an 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 Mr. Linde's employment
agreement and Mr. Zuckerman's non-compete agreement, 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.

Changes in market conditions could adversely affect the market price of our
common stock.

As with other publicly traded equity securities, the value of our common
stock depends on various market conditions which may change from time to time.
Among the market conditions that may affect the value of our common stock are
the following:

o the extent of investor interest in us;

o the general reputation of real estate investment trusts and the
attractiveness of our equity securities in comparison to other
equity securities, including securities issued by other real
estate-based companies;

o our financial performance; and

o general stock and bond market conditions.

The market value of our common stock is based primarily upon the market's
perception of our growth potential and our current and potential future earnings
and cash dividends. Consequently, our common stock may trade at prices that are
higher or lower than our net asset value per share of common stock. If our
future earnings or cash dividends are less than expected, it is likely that the
market price of our common stock will diminish.

Market interest rates may have an effect on the value of our common stock.

One of the factors that investors may consider important in deciding
whether to buy or sell shares of a real estate investment trust is the dividend
with respect to such real estate investment trust's shares as a percentage of
the price of such shares, relative to market interest rates. If market interest
rates go up, prospective purchasers of shares of our common stock may expect a
higher distribution rate on our common stock. Higher market interest rates would
not, however, result in more funds for us to distribute and, to the contrary,
would likely increase our borrowing costs and potentially decrease funds
available for distribution. Thus, higher market interest rates could cause the
market price of our common stock to go down.


24
The number of shares available for future sale could adversely affect the market
price of our stock.

As part of our initial public offering and since then we have completed
many private placement transactions where shares of capital stock of Boston
Properties, Inc. or interests in Boston Properties Limited Partnership were
issued to owners of properties we acquired or to institutional investors. This
common stock, or common stock issuable on conversion of our preferred stock or
in exchange for such interests in Boston Properties Limited Partnership, may be
sold in the public market over time pursuant to registration rights we granted
to these investors. Additional common stock reserved under our employee benefit
and other incentive plans, including stock options, may also be sold in the
public at some time in the future. Future sales of our common stock in the
public securities markets could adversely affect the price of our common stock.
We cannot predict the effect the perception in the market that such sales may
occur will have on the market price of our common stock.

We did not obtain new owner's title insurance policies in connection with
properties acquired during our initial public offering.

We acquired many of our properties from our predecessors at the completion
of our initial public offering 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 such 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 our initial public offering.

We face possible adverse changes in tax and environmental laws.

Generally, we pass through to our tenants costs resulting from increases
in real estate taxes. However, we generally do not pass through to our tenants
increases in income, service or transfer taxes. Similarly, changes in laws
increasing the potential liability for environmental conditions existing on our
properties or increasing the restrictions on discharges or other conditions may
result in significant unanticipated expenditures. These increased costs could
adversely affect our financial condition and results of operations and the
amount of cash available for payment of dividends.

At March 14, 2001, we had approximately 468 shareholders of record. This

We have adopted a policy of paying regular quarterly distributions on our
common stock and cash distributions have been paid on our common stock since our
initial public offering. In order to maintain our qualification as a REIT, we
must make annual distributions to our shareholders of at least 95% of our
taxable income (not including net capital gains). We intend that any dividend
paid in respect of our common stock during the last quarter of each year will,
if necessary, be adjusted to satisfy the REIT requirement that at least 95% of
taxable income for such taxable year be distributed.

(1) The White Paper on Funds from Operations approved by the Board of Governors
of the National Association of Real Estate Investment Trusts in March 1995
defines funds from operations as net income (loss) (computed in accordance with
generally accepted accounting principles), excluding gains (or losses) from debt
restructuring and sales of properties, plus real estate related depreciation and
amortization and after adjustments for unconsolidated partnerships and joint
ventures. During 1999, the National Association of Real Estate Investment Trusts
clarified the definition of funds from operations to include non-recurring
events, except for those that are defined as "extraordinary items" under
accounting principles generally accepted in the United States and gains and
losses from sales of depreciable operating properties. This clarification is
effective for periods ending subsequent to January 1, 2000. We adopted this
definition for the quarters ending on or after March 31, 2000. We believe that
funds from operations is helpful to investors as a measure of the performance of
an equity REIT because, along with cash flow from operating activities,
financing activities and investing activities, it provides investors with an
indication of our ability to incur and service debt, to make capital
expenditures and to fund other cash needs. We compute funds from operations in
accordance with standards established by the National Association of Real Estate
Investment Trusts which may not be comparable to funds from operations reported
by other REITs that do not define the term in accordance with the current
National Association of Real Estate Investment Trusts definition or that
interpret the current National Association of Real Estate Investment Trusts
definition differently. Funds from operations does not represent cash generated
from operating activities determined in accordance with accounting principles
generally accepted in the United States and should not be considered as an
alternative to net income (determined in accordance with accounting principles
generally accepted in the United States) as a measure of our liquidity, nor is
it indicative of funds available to fund our cash needs, including our ability
to make cash distributions.

Our funds from operations for the respective periods is calculated as follows:

Item 7. Management's Discussion and Analysis of Financial Condition and Results
of Operations

The following discussion should be read in conjunction with the selected
financial data and the historical consolidated and combined financial statements
and related notes thereto.

Forward-Looking Statements

Statements made under the caption "Risk Factors," elsewhere in this Form
10-K, in our press releases, and in oral statements we make by or with the
approval of our authorized executives are "forward-looking statements" within
the meaning of federal securities laws. When we use the words "anticipate,"
"assume," "believe," "estimate," "expect," "intend" and other similar
expressions, they generally identify forward-looking statements. Forward-looking
statements include, for example, statements relating to acquisitions and related
financial information, development activities, business strategy and prospects,
future capital expenditures, sources and availability of capital, environmental
and other regulations, and competition.

You should exercise caution in interpreting and relying on forward-looking
statements since they involve known and unknown risks, uncertainties and other
factors which are, in some cases, beyond our control and could materially affect
our actual results, performance or achievements. Some of the factors that could
cause our actual results, performance or achievements to differ materially from
those expressed or implied by forward-looking statements include, but are not
limited to, the following:

o we are subject to general risks affecting the real estate industry,
such as the need to enter into new leases or renew leases on
favorable terms to generate rental revenues, and dependence on our
tenants' financial condition;

o we may fail to identify, acquire, construct or develop additional
properties; we may develop properties that do not produce a desired
yield on invested capital; or we may fail to effectively integrate
acquisitions of properties or portfolios of properties;

o financing may not be available, or may not be available on favorable
terms;

o we need to make distributions to our stockholders for us to qualify
as a real estate investment trust, and if we need to borrow the
funds to make such distributions such borrowings may not be
available on favorable terms;

o we depend on the primary markets where our properties are located
and these markets may be adversely affected by local economic and
market conditions which are beyond our control;

o we are subject to potential environmental liabilities;

o we are subject to complex regulations relating to our status as a
real estate investment


32
trust and would be adversely affected if we failed to qualify as a
real estate investment trust; and

o market interest rates could adversely affect the market prices for
our common stock, as well as our performance and cash flow.

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 obligation to publicly update or revise any
forward-looking statement, whether as a result of new information, future events
or otherwise.

Overview

We are a fully integrated, self-administered and self-managed real estate
investment trust or "REIT" and are one of the largest owners and developers of
office and industrial properties in the United States. Our properties are
concentrated in four core markets - Boston, Washington, D.C., midtown Manhattan
and San Francisco. We conduct substantially all of our business through Boston
Properties Limited Partnership. At December 31, 2000, we owned 145 properties
totaling 37.9 million net rentable square feet, including 15 properties under
construction. The properties consisted of 134 office properties, including 103
Class A office buildings and 31 properties that support both office and
technical uses; eight industrial properties; and three hotels.

In 2000, we continued to identify and complete attractive acquisitions and
development transactions. During 2000, we added 2.1 million net rentable square
feet to our portfolio by completing acquisitions totaling approximately $167.7
million and completing developments totaling approximately $108.5 million. In
addition, as of December 31, 2000, we had construction in progress representing
a total anticipated investment of approximately $1.3 billion and a total of
approximately 4.5 million net rentable square feet.

We are focused on increasing the cash flow from our existing portfolio of
properties by maintaining high occupancy levels and increasing effective rents.
On the 3.8 million net-rentable square feet of second generation space renewed
or re-leased during the year, new net rents were on average approximately 47.1%
higher than the expiring net rents. At December 31 2000, our portfolio of office
and industrial properties was 98.9% occupied.

We also continue to strengthen our balance sheet. In October 2000, we
raised $633.8 million, net of expenses, in equity capital by completing a public
offering of our common stock. In 2000 we also issued shares of our common stock
and common and preferred units in Boston Properties Limited Partnership that
were valued when issued at $62.9 million to acquire properties and development
sites.

Results of Operations

The following discussion is based on our Consolidated Financial Statements
for the years ended December 31, 2000, 1999 and 1998.


33
From January 1, 1998 through December 31, 2000, we increased our total
from 92 properties to 145 properties and from 16.1 million net rentable square
feet to 37.9 million net rentable square feet. As a result of this rapid growth
of 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 30, 2000, 1999 and 1998 show
changes resulting from properties that we owned for each period compared (for
which each comparison we refer to as our "Same Property Portfolio") and the
changes attributable to our total portfolio.

Comparison of the year ended December 31, 2000 to the year ended December 31,
1999

The table below shows selected operating information for our total
portfolio and the 106 buildings acquired or placed in service on or prior to
January 1, 1999 and that remained in the total portfolio through December 31,
2000 (which comprise the Same Property Portfolio for the years ended December
31, 2000 and 1999):

The increase in rental revenues in our Same Property Portfolio for these
years is primarily a result of an overall increase in rental rates on new leases
and rollovers, in addition to an increase in occupancy from year to year and an
increase in termination fees from $2.3 million to $3.3 million. The occupancy
for our Same Property Portfolio increased from 97.4% as of December 31, 1999 to
98.8% as of December 31, 2000. The increase in rental revenues in our total
portfolio is primarily the result of properties we acquired or placed-in-service
after January 1, 1998.

The decrease in development and management services income in the total
portfolio is mainly due to contracts expiring during 1999 and 2000.

The increase in interest and other income in the total portfolio is a
result of interest earned on proceeds received from the public offering of our
common stock in October 2000.

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 $4.0
million, or 4.2%. Small increases in other property-related expenses account for
the remaining increase. Property operating expenses in our total portfolio


34
increased due to properties we acquired or placed-in-service after January 1,
1999 as well as increases in other property-related expenses.

General and administrative expenses increased due to increases in the
overall size of our total portfolio since January 1, 1999. In addition, we
incurred a $3.0 million charge related to the departure of two senior employees,
which included a non-cash charge of approximately $2.0 million.

Interest expense for our total portfolio increased due to net increase in
mortgage indebtedness and our unsecured revolving line of credit with Fleet
National Bank, as agent, from $3.3 billion to $3.4 billion.

Depreciation and amortization expense for our Same Property Portfolio
increased as a result of capital and tenant improvements made during 2000.
Depreciation and amortization expense for our total portfolio increased as a
result of properties we acquired or placed-in-service after January 1, 2000 and

</TABLE>

The increase in rental revenues in our Same Property Portfolio for these
years is primarily a result of an overall increase in rental rates on new leases
and rollovers as well as an increase in termination fees from $0.7 million to
$2.3 million, offset by a small decrease in occupancy from year to year. The
occupancy for our Same Property Portfolio decreased from 97.8% as of December
31, 1998 to 97.4% as of December 31, 1999. The increase in rental revenues in
our total portfolio is primarily the result of properties we acquired or
placed-in-service after January 1, 1998.


35
The increase in development and management services income in our total
portfolio is a result of fees earned on new projects begun during the year, and
increased fees on projects in progress.

The decrease in interest and other income in our total portfolio is a
result of less cash and cash equivalents on deposit during 1999. During 1998,
our average cash balances were higher due to $765.0 million of net proceeds
received from a public offering of our common stock in January 1998.

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 real estate taxes. Real estate taxes increased
approximately $1.0 million due to higher property tax assessments. Small
increases in other property-related expenses account for the remaining increase.
Property operating expenses in our total portfolio increased mainly due to
properties we acquired or placed-in service after January 1, 1998.

General and administrative expenses increased due to the significant
increase in the size of our total portfolio since January 1, 1998. We hired
additional employees as a result of acquisitions.

Interest expense for our total portfolio increased due to an increase in
mortgage indebtedness and an increase in borrowing under our unsecured revolving
line of credit with Fleet National Bank, as agent.

Depreciation and amortization expense for our Same Property Portfolio
increased as a result of capital and tenant improvements made during 1999.
Depreciation and amortization expense for our total portfolio increased
primarily as a result of properties we acquired or placed- in-service after
January 1, 1998 and related capital and tenant improvements.

Liquidity and Capital Resources

Cash and cash equivalents were $281.0 million and $12.0 million at
December 31, 2000 and December 31, 1999, respectively. The increase was a result
of the following increases and decreases in cash flows:

<TABLE>
<CAPTION>
Year Ended December 31,
(in millions) 2000 1999 $ Change
---- ---- --------
<S> <C> <C> <C>
Cash Provided by Operating Activities $339.7 $303.5 $ 36.2
Cash Used for Investing Activities ($573.4) ($655.0) $ 81.6
Cash Provided by Financing Activities $502.6 $351.4 $151.2
</TABLE>

The increase in cash provided by operating activities is primarily due to
the increase in net income resulting from the 1999 and 2000 property
acquisitions and developments placed-in- service and our 2000 Same Property
Portfolio.

Net cash used for investing activities decreased from $655.0 million for
the year ended


36
December 31, 1999 to $573.4 million for the year ended December 31, 2000 mainly
due to fewer property acquisitions during 2000. The cash and capital used in the
2000 investing activities was primarily for the following transactions:

Acquisitions, Dispositions and Development Transactions

o On January 12, 2000, we acquired our joint venture partner's 75%
interest in One and Two Reston Overlook, for cash of approximately
$15.2 million and the assumption of approximately $69.0 million in
debt.

o On March 1, 2000, we acquired three Class A office buildings
totaling approximately 408,163 square feet at Carnegie Center in
Princeton, New Jersey, under the terms of the original Carnegie
Center Portfolio acquisition entered into in June 1998. We acquired
the properties 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 Boston Properties Limited
Partnership valued at approximately $17.5 million. The acquisition
was reviewed and approved by a vote of our independent directors.

o On May 12, 2000, an unrelated third party acquired partial interests
in two properties that we previously owned in their entirety. We
retained a 51% interest in the first property, Metropolitan Square,
a 582,194-square foot office property in Washington, DC and a 25%
interest in the second property, 140 Kendrick Street, a
381,000-square foot build-to-suit development property in Needham,
Massachusetts. The interests in the properties were acquired for
cash of approximately $46.7 million and the assumption of debt of
approximately $88.2 million and resulted in a gain to us of $0.4
million.

o On August 22, 2000, we acquired the remaining 50% interest in the
development rights at the Prudential Center in Boston, Massachusetts
for approximately $18.2 million, which was funded through the
issuance of 439,059 shares of our common stock.

o On September 13, 2000, we acquired a 35% interest in 265 Franklin
Street, a 325,699 square foot office property in Boston,
Massachusetts through a joint venture. Our interest in this property
was acquired with cash of approximately $10.6 million and new debt
financing of approximately $23.8 million.

o On September 29, 2000, we sold 910 and 930 Clopper Road, two
office/technical use properties totaling 240,596 square feet in
Gaithersburg, Maryland for approximately $24.1 million. This sale
resulted in a loss to us of approximately $0.8 million.

o On October 13, 2000, we sold 1950 Stanford Court, a single story
industrial building totaling 53,250 square feet, and an adjacent
parcel of land totaling approximately 2 acres in Landover, Maryland,
for approximately $2.2 million. This sale resulted in a gain to us
of approximately $0.1 million.

o On December 1, 2000, we acquired the leasehold interest and ground
rent credits at the site of the future Times Square Tower in midtown
Manhattan, for approximately $165.1 million in cash. This
development will consist of a 47-floor, 1.2 million square foot
office tower.

o We acquired additional land parcels in Greater Boston, Greater
Washington, D.C. and Greater San Francisco for potential future
developments for an aggregate amount of


37
approximately $39.7 million, of which approximately $12.5 million
was funded with cash and approximately $27.2 million was funded
through the issuance of common and preferred units of Boston
Properties Limited Partnership.

o We placed six Class A office buildings in service which resulted in
a total investment during 2000 of approximately $43.4 million. We
began or continued construction on additional Class A office
buildings and incurred approximately $319.6 million of construction
costs during 2000. Our properties under construction as of December
31, 2000 were as follows:

(1) Represents our share of the investment.

In addition, we incurred costs of approximately $37.0 million on
properties in the preconstruction phase of the development process.

Cash provided by financing activities increased by $151.2 million for
2000, compared to the year ended 1999. During 2000, we received proceeds from
new debt totaling approximately $976.4 million. This was offset by $525.2
million of paydowns and principal payments during 2000. The remaining increase
is mainly due to the increase in proceeds received from the public offering
described below.

Recent Equity Financing

On October 31, 2000, we completed a public offering of 17,110,000 shares
of our common stock (including 2,110,000 shares issued pursuant to the exercise
of the underwriters' overallotment option) at a price per share of $39.0625. Our
proceeds from this public offering, net of underwriter's discount and offering
costs, were approximately $633.8 million.

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. Our
primary market risk results from our long-term 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 by matching long-term leases with long-term fixed rate non-recourse
debt of similar duration. In


38
addition, we maintain a major unencumbered portion of our portfolio. We continue
to follow a conservative strategy of pre-leasing development projects on a
long-term basis to strong tenants in order to achieve the most favorable
construction and permanent financing terms. Approximately 85% of our outstanding
debt has fixed interest rates, which minimizes the interest rate risk until the
maturity of such outstanding debt.

We have entered into hedging arrangements with financial institutions. Our
primary objective when undertaking hedging transactions and derivative positions
is to reduce our floating rate exposure, which, in turn, reduces the risks that
the variability of cash flows imposes on variable rate debt. Our strategy
protects us against future increases in interest rates. At December 31, 2000, we
had hedge contracts totaling $450.0 million. The hedging agreements provide for
a fixed interest rate when the London Interbank Offered Rate ("LIBOR") is less
than 5.76% and when LIBOR is greater than 6.35% or 7.95% for terms ranging from
three to five years per the individual hedging agreements. In addition, we have
an interest rate swap agreement for a total of $213.0 million which provides for
a fixed interest rate of 6.0% through September 11, 2002. We will consider
entering into additional hedging agreements with respect to all or a portion of
our variable rate 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 hedging agreements, decreases in interest rates could increase interest
expense as compared to the underlying variable rate debt and could result in us
making payments to unwind such agreements.

At December 31, 2000, our variable rate debt outstanding was approximately
$404.1 million. At December 31, 2000, the average interest rate on variable rate
debt was approximately 8.56%. Taking the hedging contracts into consideration,
if market interest rates on our variable rate debt were to increase by ten
percent (approximately 86 basis points), total interest would increase
approximately $1.7 million.

These amounts were determined solely by considering the impact of
hypothetical interest rates on our financial instruments. Due to the uncertainty
of specific actions we may undertake to minimize possible effects of market
interest rate increases, this analysis assume no changes in our financial
structure.

Capitalization

At December 31, 2000, our total consolidated debt was approximately $3.4
billion. The weighted average rate of our consolidated indebtedness was 7.37%
and the weighted average maturity was approximately 6.2 years.

Our total market capitalization was approximately $8.8 billion at December
31, 2000. Total market capitalization was calculated using the December 31, 2000
closing stock price of $43.50 per share and includes the following: (1)
86,630,089 shares of our common stock, (2) 23,862,206 of common units of Boston
Properties Limited Partnership (excluding common units held by Boston

We utilize our $605.0 million unsecured revolving line of credit
principally to fund development of properties, other land and property
acquisitions and for working capital purposes. Our unsecured revolving line of
credit is a recourse obligation of Boston Properties Limited Partnership. Our
ability to borrow under our unsecured revolving line of credit is subject to our
compliance with a number of customary financial and other covenants on an
ongoing basis, including: (1) loan-to-value ratio against our total borrowing
base not to exceed 55%, unless our leverage ratio exceeds 60%, in which case it
is not to exceed 50%, (2) a loan-to-value ratio against the total secured
borrowing base not to exceed 55%, (3) debt service coverage ratio of 1.40 for
our borrowing base, or 1.50 if our leverage ratio equals or exceeds 60%, and
1.30 for us as a whole for full fixed charges, (4) a leverage ratio not to
exceed 60%, however five consecutive quarters (not including the two quarters
prior to expiration) can go to 65% (5) an interest rate applicable to any
amounts drawn under our unsecured revolving line of credit for Eurodollar based
loans shall be equal to a floating rate based on a spread over Eurodollar equal
to 105 to 170 basis points, (6) limitations on additional indebtedness and
stockholder distributions, and (7) a minimum net worth requirement.

At December 31, 2000, we had issued letters of credit totaling $3.3
million and had the ability to borrow an additional $601.7 million under our
unsecured revolving line of credit. As of March 14, 2001 there was zero
outstanding under our unsecured revolving line of credit.

NOTE: LIBOR and Eurodollar rate contracts in effect on December 31, 2000 ranged
from 6.56% to 6.82%. The LIBOR and Eurodollar rates at December 31, 2000 were
6.57% and 6.58%, respectively.

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 our REIT qualifications 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.

We expect to meet liquidity requirements for periods beyond twelve months
for the costs of development, property acquisitions, scheduled debt maturities,
major renovations, 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 of Boston Properties Limited
Partnership and equity securities of Boston Properties, Inc. In addition, we may
finance the development, redevelopment or acquisition of additional properties
by using our unsecured


42
revolving line of credit.

Rental revenues, operating expense reimbursement income from tenants, and
income from the 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 include third party fees generated by our office and
industrial real estate management, leasing, development and construction
businesses. Consequently, we believe our revenue will continue to provide the
necessary funds for operating expenses, debt service and recurring capital
expenditures.

During the year ended December 31, 2000, we paid or declared quarterly
dividends totaling $2.04 per common share (consisting of $.45 related to the
quarter ended March 31, 2000 and $.53 related to each of the quarters ended June
30, 2000, September 30, 2000 and December 31, 2000). We intend to continue
paying dividends quarterly.

Funds from Operations

Pursuant to the National Association of Real Estate Investment Trusts
revised definition of Funds from Operations, we calculate Funds From Operations
by adjusting net income (loss) (computed in accordance with accounting
principles generally accepted in the United States, including non-recurring
items), for gains (or losses) from debt restructuring and sales of properties
(except gains and losses from sales of depreciable operating properties), real
estate related depreciation and amortization and unconsolidated partnerships and
joint ventures. We believe that Funds From Operations is helpful to investors as
a measure of the performance of an equity REIT because, along with cash flow
from operating activities, financing activities and investing activities, it
provides investors with an indication of our ability to incur and service debt,
to make capital expenditures and to fund other cash needs. We compute Funds From
Operations in accordance with standards established by the National Association
of Real Estate Investment Trusts which may not be comparable to Funds From
Operations reported by other REITs that do not define the term in accordance
with the current National Association of Real Estate Investment Trusts or that
interpret the definition differently. Funds From Operations does not represent
cash generated from operating activities determined in accordance with
accounting principles generally accepted in the United States and should not be
considered as an alternative to net income (determined in accordance with
accounting principles generally accepted in the United States) as a measure of
our liquidity, nor is it indicative of funds available to fund our cash needs,
including our ability to make cash distributions.

Environmental Matters

Some of our properties are located in urban and industrial areas where
fill or current or historical industrial uses of the areas have caused site
contamination. With respect to all of our properties, independent environmental
consultants have been retained in the past 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. These environmental
assessments have not revealed any environmental conditions that we believe will
have a material adverse


43
effect on our business, assets or results of operations, and we are not aware of
any other environmental condition with respect to any of our properties which we
believe would have such a material adverse effect. However, we are aware of
environmental conditions at three of our properties that may require
remediation:

On January 15, 1992, a property in Massachusetts was listed by the state
regulatory authority as an unclassified Confirmed Disposal Site in connection
with groundwater contamination. We engaged a specially licensed environmental
consultant to perform the necessary investigation and assessment and to prepare
submittals to the state regulatory authority. On August 1, 1997, our consultant
submitted to the state regulatory authority a Phase I - Limited Site
Investigation Report and Downgradient Property Status Opinion. This Opinion
concluded that the property qualifies for Downgradient Property Status under the
state regulatory program, which eliminates certain deadlines for conducting
response actions at a site and may qualify us for liability relief under recent
statutory amendments. 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 such response actions, we will take any necessary further
response actions.

An investigation at another property in Massachusetts identified
groundwater contamination. We engaged a specially licensed environmental
consultant to perform the necessary investigation and assessment and to prepare
submittals to the state regulatory authority. On March 11, 1998, our consultant
submitted to the state regulatory authority a Release Notification and
Downgradient Property Status Opinion. This Opinion concluded that the property
qualifies for Downgradient Property Status under the state regulatory program,
which eliminates certain deadlines for conducting response actions at a site and
may qualify us for liability relief under recent statutory amendments. 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 such response
actions, we will take any necessary further response actions.

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 anticipate development of an office park
on the property. Pursuant to the property acquisition agreement, Exxon has
agreed 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, including up to
$500,000 for the premium costs associated with construction-related management
of contaminated soil not otherwise subject to remediation by Exxon. Any
indemnity claim may be subject to various defenses. Our affiliate has engaged a
specially licensed environmental consultant to oversee the management of
contaminated soil that may be disturbed in the course of construction.

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


44
Newly Issued Accounting Standard

As of January 1, 2001, we adopted Statement of Financial Accounting
Standard ("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging
Activities" as amended by SFAS No. 137 and No. 138 ("SFAS No. 133"). 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 our 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 in SFAS No. 133 are required to
be reported 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 loss until the
forecasted transactions occur and the ineffective portions are recognized in
earnings.

The nature of our derivatives include investments in warrants to purchase
shares of common stock of other companies and interest rate agreements to
protect against changes in interest rates for variable rate debt. 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. We
had been recording the warrants at fair value through other comprehensive loss
as available for sale securities under SFAS No. 115. We estimate that upon
adoption of SFAS No. 133, we will reclass approximately $6.8 million, the fair
value of the warrants, from accumulated other comprehensive loss to a cumulative
effect of a change in accounting principle. Our interest rate protection
agreements will be designated as hedging instruments in qualifying cash flow
hedges. As such, we estimate that, upon adoption of SFAS No. 133, we will record
an asset of approximately $0.2 million and record a liability of approximately
$11.4 million for the fair values of these agreements. The offset for these
entries will be to a cumulative effect of a change in accounting principle and
accumulated other comprehensive loss, respectively. Finally, we estimate we will
write-off deferred charges of approximately $1.6 million as a cumulative effect
of a change in accounting principle.

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.


45
Item 7a. Quantitative and Qualitative Disclosures about Market Risk

Approximately $3.0 billion of our long-term debt bears interest at fixed
rates, and therefore the fair value of these instruments is affected by changes
in the market interest rates. The following table presents principal cash flows
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 on the variable rate debt as of December 31, 2000 ranged
from LIBOR or Eurodollar plus 1.50% to LIBOR or Eurodollar plus 2.00%.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of
Boston Properties, Inc.:

In our opinion, the accompanying consolidated financial statements and the
financial statement schedule listed in the accompanying index present fairly, in
all material respects, the financial position of Boston Properties, Inc. (the
"Company") at December 31, 2000 and 1999, and the results of its operations and
its cash flows for each of the three years in the period ended December 31, 2000
in conformity with accounting principles generally accepted in the United States
of America. These financial statements and financial statement schedule are the
responsibility of the Company'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 and financial statement schedule are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements and financial
statement schedule, 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.

Partnership (the "Operating Partnership") and at December 31, 2000, owned an
approximate 71.9% 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.

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

Properties

At December 31, 2000, the Company owned a portfolio of 145 commercial real
estate properties (136 properties at December 31, 1999) (the "Properties")
aggregating more than 37.9 million net rentable square feet (including 15
properties under construction totaling approximately 4.5 million net rentable
square feet). The Properties consist of 134 office properties, including 103
Class A office properties and 31 Research and Development properties; eight
industrial properties; three hotels; and structured parking for 17,179 vehicles
containing approximately 6.0 million square feet. In addition, the Company owns
or controls 49 parcels of land totaling 558.3 acres (which will support
approximately 10.6 million net rentable square feet of development). The Company
considers Class A office properties to be centrally located buildings that are
professionally managed and maintained, that attract high-quality tenants and
command upper-tier rental rates, and that are modern structures or have been
modernized to compete with newer buildings. The Company considers Research and
Development properties to be properties that support office, research and
development and other technical uses.

Basis of Presentation

The consolidated financial statements of the Company include all the
accounts of the Company, its majority-owned Operating Partnership, and
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. The Company periodically
reviews its properties to determine if its carrying costs will be recovered from
future operating cash flows. If the Company determines that an impairment has
occurred, those assets shall be reduced to fair value. No such impairment losses
have been recognized to date.

The cost of buildings and improvements include the purchase price of
property, legal fees and acquisition costs. The costs of buildings under
development include the capitalization of interest, property taxes and other
costs incurred during the period of development.

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 Company's cash and cash equivalents are held at major commercial banks. The
Company has not experienced any losses to date on its invested cash.

Escrows

Escrows include amounts established pursuant to various agreements for
security deposits, property taxes, insurance and other costs. At December 31,
2000, proceeds of $57.6 million from the permanent financing of a development
property have been deposited into an escrow account and recorded in mortgage
notes and bonds payable until the completion of construction on the development
property, at which time the construction loan will be repaid and the proceeds
will be available to the Company.

(dollars in thousands, except per share amounts)

Investments in Securities

The Company accounts for investments in securities of publicly traded
companies in accordance with Statement of Financial Accounting Standard ("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 115. As of December 31, 2000, the fair value of the
investments in common stocks and warrants was approximately $7.0 million. The
gross unrealized holding loss of approximately $11.7 million is included in
accumulated other comprehensive loss on the consolidated balance sheets. At
December 31, 1999, the investments in securities were reflected at cost in the
consolidated balance sheet, as they were not considered marketable under SFAS
No. 115.

Deferred Charges

Deferred charges include leasing costs and financing fees. Fees and costs
incurred in the successful negotiation of leases, including brokerage, legal and
other costs have been deferred and are being amortized on a straight-line basis
over the terms of the respective leases. Fees and costs incurred to obtain
long-term 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 of financing or upon the early
termination of the lease. 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 Company 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 Company is reflected on the
consolidated balance sheets, and the Company's share of net income or loss from
the joint ventures is included on the consolidated statements of operations.

The Company 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.

Offering Costs

Underwriting commissions and offering costs have been reflected as a
reduction of additional paid-in capital.

Dividends

Earnings and profits, which determine the taxability of dividends to
shareholders, will differ from income reported for financial reporting purposes
due to the differences for federal income tax purposes primarily in the
estimated useful lives used to compute depreciation. Dividends declared
represented 100% ordinary income for federal income tax purposes for the


63
BOSTON PROPERTIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(dollars in thousands, except per share amounts)

years ended December 31, 2000, 1999 and 1998.

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 $13,071, $17,044, and $18,510 for the years ended December 31, 2000,
1999 and 1998, respectively. Property operating cost reimbursements due from
tenants for common area maintenance, real estate taxes and other recoverable
costs are recognized in the period the expenses are incurred.

Accrued rental income represents rental income earned in excess of rent
payments received pursuant to the terms of the individual lease agreements, net
of an allowance for doubtful accounts.

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.

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.

The Company has entered into certain interest rate protection agreements
to reduce the impact of changes in interest rates on its variable rate debt.
Amounts paid for the agreements are amortized over the lives of the agreements
on a basis that approximates the effective interest method.

Earnings Per Share

Basic earnings per share ("EPS") is computed by dividing net income by the
weighted average number of shares of Common Stock outstanding during the year.
Diluted EPS reflects the potential dilution that could occur from shares
issuable through stock-based compensation including stock options, conversion of
the minority interests in the Operating Partnership and conversion of the
preferred stock of the Company.

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. Mortgage notes payable have aggregate carrying values that
approximate their estimated fair values based upon the remaining maturities for
certain debt and interest rates for debt with similar terms and remaining
maturities. The fair value of these financial instruments were not materially
different from their carrying or contract values.

Income Taxes

The Company has elected to be treated as a REIT under Sections 856 through
860 of the Internal Revenue Code of 1986, as amended (the "Code"), commencing
with its taxable year


64
BOSTON PROPERTIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(dollars in thousands, except per share amounts)

ended December 31, 1997. As a result, the Company generally will not be subject
to federal corporate income tax on its taxable income that is distributed to its
shareholders. A REIT is subject to a number of organizational and operational
requirements, including a requirement that it currently distribute at least 95%
of its annual taxable income (90% effective January 1, 2001). The Company's
policy is to distribute 100% of its taxable income. Accordingly, no provision
has been made for federal income taxes in the accompanying consolidated
financial statements.

To assist the Company in maintaining its status as a REIT, the Company
leases 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, respectively, are the sole member-managers. Marriott
International, Inc. manages these hotel properties under the Marriott(R) name
pursuant to management agreements with the lessee. Rental revenue from these
leases totaled approximately $38.1 million, $32.1 million and $25.7 million for
the years ended December 31, 2000, 1999 and 1998, respectively.

The net difference between the tax basis and the reported amounts of the
Company's assets and liabilities is approximately $1.2 billion as of December
31, 2000 and 1999.

Certain entities included in the Company's consolidated financial
statements are subject to District of Columbia franchise taxes. Franchise taxes
are recorded as operating expenses in the accompanying consolidated financial
statements.

Reclassifications

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

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 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,
allowances for doubtful accounts and accrued rent. Actual results could differ
from those estimates.

6. Mortgage Notes and Bonds Payable

The Company had outstanding mortgage notes and bonds payable totaling
$3,414,891 and $2,955,584 as of December 31, 2000 and 1999, respectively, 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 and bonds payable totaled approximately
$3,010,760 and $2,820,650 at December 31, 2000 and 1999, respectively, with
interest rates ranging from 6.40% to 8.59% (averaging 7.21% and 7.06% at
December 31, 2000 and 1999, respectively).

Variable rate mortgage notes payable (including construction loans
payable) totaled approximately $404,131 and $134,934 at December 31, 2000 and
1999, respectively, with interest rates ranging from 1.00% above the London
Interbank Offered Rate ("LIBOR") (6.57% and 5.82% at December 31, 2000 and 1999,
respectively) to 2.00% above LIBOR.

At December 31, 2000, the Company had hedge contracts totaling $450.0
million. The hedging agreements provide for a fixed interest rate when LIBOR is
less than 5.76% and when LIBOR is greater than 6.35% or 7.95% for terms
remaining from two to four years per the individual hedging agreements. In
addition, the Company has an interest rate swap agreement for a total of $213.0
million which provides for a fixed interest rate of 6.0% through September 11,
2002.

Mortgage notes payable aggregating approximately $190,492 and $207,132 at

31, 2000 and 1999, respectively, are subject to periodic scheduled interest rate
increases. Interest expense for these mortgage notes payable is computed using
the effective interest method. Mortgage notes payable aggregating approximately
$224,818 and $320,110 at December 31, 2000 and 1999, respectively, 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
$3,579, $4,742 and $2,656 for the years ended December 31, 2000, 1999 and 1998,
respectively. The cumulative liability related to these accounting methods was
$9,642 and $13,575 at December 31, 2000 and 1999, respectively, and is included
in mortgage notes and bonds payable.

Combined aggregate principal payments of mortgage notes and bonds payable
at December 31, 2000 are as follows:

2001 $ 193,947
2002 $ 306,223
2003 $ 434,342

2005 $ 269,378
Thereafter $2,076,037

7. Unsecured Line of Credit

As of December 31, 2000, the Company has an agreement for a $605,000
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, depending upon the Company's applicable leverage ratio, or
the lender's prime rate. The Unsecured Line of Credit requires monthly payments
of interest only.

The outstanding balance of the Unsecured Line of Credit was $0 and
$366,000 at December 31, 2000 and 1999, respectively. The weighted average
balance outstanding was approximately $233,052 and $256,685 during the year
ended December 31, 2000 and 1999, respectively. The weighted-average interest
rate on amounts outstanding was approximately 7.65% and 6.50% during the year
ended December 31, 2000 and 1999, respectively.

The Company's ability to borrow under the Unsecured Line of Credit is
subject to the Company's ongoing compliance with a number of financial and other
covenants, including, but not limited to, maintaining a certain ratio of secured
indebtedness to total asset value, as defined.

8. Commitments and Contingencies

Concentrations of Credit Risk

Management of the Company 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 Company's properties
are geographically diverse and the tenants operate in a variety of industries,
to the extent the Company has a significant


68
BOSTON PROPERTIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(dollars in thousands, except per share amounts)

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 Company.

Legal Matters

The Company 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 Company.

Environmental Matters

Some of the Properties are located in urban and industrial areas where
fill or current or historical industrial uses of the areas have caused site
contamination. With respect to all of the Properties, independent environmental
consultants have been retained in the past 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 on all of the
Properties. These environmental assessments have not revealed any environmental
conditions that the Company believes will have a material adverse effect on its
business, assets or results of operations, and the Company is not aware of any
other environmental condition with respect to any of the Properties which the
Company believes would have such a material adverse effect.

On January 15, 1992, a property in Massachusetts was listed by the state
regulatory authority as an unclassified Confirmed Disposal Site in connection
with groundwater contamination. The Company engaged a specially licensed
environmental consultant to perform the necessary investigation and assessment
and to prepare submittals to the state regulatory authority. On August 1, 1997,
such consultant submitted to the state regulatory authority a Phase I - Limited
Site Investigation Report and Downgradient Property Status Opinion. This Opinion
concluded that the property qualifies for Downgradient Property Status under the
state regulatory program, which eliminates certain deadlines for conducting
response actions at a site and may qualify the Company for liability relief
under recent statutory amendments. Although the Company believes that the
current or former owners of the upgradient source properties may ultimately be
responsible for some or all of the costs of such response actions, the Company
will take any necessary further response actions.

An investigation at an additional property in Massachusetts identified
groundwater contamination. The Company engaged a specially licensed
environmental consultant to perform the necessary investigation and assessment
and to prepare submittals to the state regulatory authority. On March 11, 1998,
the consultant submitted to the state regulatory authority a Release
Notification and Downgradient Property Status Opinion. This Opinion concluded
that the property qualifies for Downgradient Property Status under the state
regulatory program, which eliminates certain deadlines for conducting response
actions at a site and may qualify the Company for liability relief under recent
statutory amendments. Although the Company believes that the current or former
owners of the upgradient source properties may ultimately be responsible for
some or all of the costs of such response actions, the Company will take any
necessary further response actions.

In February 1999, an affiliate of the Company 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 Company anticipates
development of an office park on the property. Pursuant to the property
acquisition agreement, Exxon has agreed to (1) bear the liability arising from
releases or discharges of oil and hazardous substances which occurred at the
site prior to the Company's ownership, (2) continue remediating such releases
and discharges as necessary and appropriate to comply with applicable
requirements, and (3) indemnify the purchaser for certain losses arising from
preexisting site conditions, including up to $500,000 for the premium costs
associated with construction-related management of contaminated soil not
otherwise subject to remediation by Exxon. Any indemnity claim may be subject to
various defenses. The affiliate has engaged a specially licensed environmental
consultant to perform necessary pre-construction assessment activities and to
oversee the management of contaminated soil that may be disturbed in the course
of construction.

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

Development

The Company has entered into contracts for the construction and renovation
of properties currently under construction. Commitments under these arrangements
totaled approximately $677,654 and $759,501 at December 31, 2000 and 1999,
respectively.

Sale of Property

The Operating Partnership Agreement provides that, until June 23, 2007,
the Operating Partnership may not sell or otherwise transfer four designated
properties in a taxable transaction without the prior written consent of the
Chairman and Chief Executive Officer. In connection with the acquisition or
contribution of 31 other Properties, the Company entered into similar agreements
for the benefit of the selling or contributing parties which specifically state
the Company will not sell or otherwise transfer the Properties in a taxable
transaction until a period ranging from June 2002 to November 2008. The
Operating Partnership is not required to obtain the consent from a party
protected thereby if such party does not continue to hold at least a specified
percentage of such party's original OP Units.

9. Minority Interests

Minority interests primarily relate to the interests of the Company in the
Operating Partnership. As of December 31, 2000, the minority interest in the
Operating Partnership consisted of 23,862,206 OP Units and 9,357,536 Preferred
Units held by parties other than the Company.

On March 1, 2000, the Operating Partnership issued 577,817 OP Units valued
at approximately $17.5 million in connection with the acquisition of three
office properties at Carnegie Center in Princeton, New Jersey.


70
BOSTON PROPERTIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(dollars in thousands, except per share amounts)

On June 19, 2000, the Operating Partnership issued 82,215 OP Units valued
at approximately $3.0 million in connection with the acquisition of a land
parcel in Chelmsford, Massachusetts.

On December 11, 2000, the Operating Partnership issued 650,876 Series Z
Preferred Units of limited partnership of the Operating Partnership (the "Series
Z Preferred Units"), valued at approximately $24.2 million, in connection with
the acquisition of a 3.7-acre site known as the Plaza at Almaden in San Jose,
California.

The Preferred Units at December 31, 2000 consist of 2,493,529 Series One
Preferred Units of limited partnership in the Operating Partnership (the "Series
One Preferred Units"), which bear a preferred distribution of 7.25% per annum on
a liquidation preference of $34.00 per unit and are convertible into OP Units at
a rate of $38.25 per Preferred Unit; 6,213,131 Series Two and Three Preferred
Units of limited partnership in the Operating Partnership (the "Series Two and
Three Preferred Units"), which bear a preferred distribution at an increasing
rate, ranging from 5.00% to 7.00% per annum on a liquidation preference of
$50.00 per unit and are convertible into OP Units at a rate of $38.10 per
Preferred Unit; and 650,876 Series Z Preferred Units, which bear distributions
at a rate ranging from zero to the distribution rate of an OP Unit, with a
liquidation preference of $37.25 per unit and are convertible into OP Units at a
rate equal to the greater of (1) one for one or (2) $37.25 divided by the fair
market value of an OP Unit. Distributions to holders of Preferred Units are
recognized on a straight-line basis that approximates the effective interest
method.

10. Redeemable Preferred Stock and Stockholders' Equity

On August 22, 2000, the Company issued 439,059 unregistered shares of
Common Stock for approximately $18.2 million, in connection with its acquisition
of the remaining 50% interest in the development rights associated with the
Prudential Center in Boston, Massachusetts.

On October 31, 2000, the Company completed a public offering of 17,110,000
shares of Common Stock at a price per share to the public of $39.0625 (including
2,110,000 shares issued as a result of the exercise of an overallotment option
by the underwriters on November 2, 2000), resulting in net proceeds to the
Company, net of underwriter's discount and offering costs, of approximately
$633.8 million.

As of December 31, 2000, the Company had 86,630,089 shares of Common Stock
and 2,000,000 shares of Series A Convertible Redeemable Preferred Stock (the
"Preferred Stock") outstanding. The Preferred Stock bears a preferred dividend
at an increasing rate, ranging from 5.00% to 7.00% per annum on a liquidation
preference of $50.00 per share and are convertible into Common Stock at a rate
of $38.10 per share. The preferred dividend is recognized on a straight-line
basis that approximates the effective interest method. These shares of Preferred
Stock are not classified as equity in certain instances as they are convertible
into shares of Common Stock at the election of the holder after December 31,
2002 or are redeemable for cash at the election of the holder in six annual
tranches commencing on May 12, 2009.

12. Segment Reporting

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

Asset information by reportable 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. Development and
management services revenue, interest and other revenue, general and
administrative expenses and interest expense are not included in operating

15. Employee Benefit Plan

Effective January 1, 1985, the predecessor to the Company adopted a
401(k) Savings Plan (the "Plan") for its employees. Under the Plan, as amended,
employees as defined, are eligible to participate in the Plan after they have
completed three months of service. In addition, participants may elect to make
an after-tax contribution of up to 10% of their wages. Upon formation, the
Company adopted the Plan and the terms of the Plan.

In November 1999, the Company amended the Plan by increasing the Company's
matching contribution to 200% of the first 3% from 200% of the first 2% of
participant's pay contributed (utilizing pay that is not in excess of $100) and
by eliminating the vesting requirement. The effective date of these changes was
January 1, 2000.

The Plan provides that matching employer contributions are to be
determined at the discretion of the Company. The Company's matching contribution
for the years ended December 31, 2000, 1999 and 1998 was $1,702, $889 and $583,
respectively.

16. Stock Option and Incentive Plan

The Company has established a stock option and incentive plan 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 available for option grant 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 outstanding, on a
fully converted basis (excluding Preferred Stock). The strike price on the
shares granted is equal to the market price of the Company's Common Stock on the
grant date. Shares granted under the plan vest over three or five years. The
term of each option is ten years from the date of grant.

During the year ended December 31, 2000, the Company issued 34,822 shares
of restricted stock valued at approximately $1.0 million ($30.4375 per share).
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. There was no restricted stock
issued prior to the year 2000.

A summary of the status of the Company's stock options as of December 31,
2000, 1999 and 1998 and changes during the years ended December 31, 2000, 1999

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

The compensation cost under SFAS 123 for the stock performance-based plan
would have been $11,993, $10,443 and $6,847 for the years ended December 31,
2000, 1999 and 1998, respectively. Had compensation cost for the Company's
grants for stock-based compensation plans been determined consistent with SFAS
123, the Company's net income, and net income per common share for 2000, 1999
and 1998 would approximate the pro forma amounts below:

2000 1999 1998
-------- -------- -------
Net income $134,433 $103,504 $86,265
Net income per common share - basic $ 1.88 $ 1.56 $ 1.42
Net income per common share - diluted $ 1.85 $ 1.55 $ 1.41

The effects of applying SFAS 123 in this pro forma disclosure are not
indicative of future amounts. SFAS 123 does not apply to future anticipated
awards.

17. Employee Stock Purchase Plan

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 valuation period, as defined. The Company
issued 11,105 and 5,115 shares under the Stock Purchase Plan as of December 31,
2000 and 1999, respectively. No shares were issued in 1998.

19. Newly Issued Accounting Standard

As of January 1, 2001, the Company adopted SFAS No. 133, "Accounting for
Derivative Instruments and Hedging Activities" as amended by SFAS No. 137 and
SFAS No. 138 ("SFAS No. 133"). 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 Company'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 in SFAS No. 133 are required to be reported 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 loss until the forecasted
transactions occur and the ineffective portions are recognized in earnings.

The nature of the Company's derivatives includes investments in warrants
to purchase shares of common stock of other companies and interest rate
agreements to protect against changes in interest rates for variable rate debt.
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 Company has been recording the warrants at fair value through accumulated
other comprehensive loss as available-for-sale securities under SFAS No. 115.
The Company estimates that, upon adoption of SFAS No. 133, it will reclass
approximately $6.8 million, the fair value of the warrants, from accumulated
other comprehensive loss to a cumulative effect of a change in accounting
principle. The Company's interest rate protection agreements will be designated
as hedging instruments in qualifying cash flow hedges. As such, the Company
estimates that upon adoption of SFAS No. 133, it will record an asset of
approximately $0.2 million and record a liability of approximately $11.4 million
for the fair values of these agreements. The offset for these entries will be to
a cumulative effect of a change in accounting principle and accumulated other
comprehensive loss, respectively. Finally, the Company estimates it will
write-off deferred charges of approximately $1.6 million as a cumulative effect
of a change in accounting principle.
