ITEM 1. BUSINESS.

GENERAL

    Beacon Capital Partners, Inc. ("we" or the "Company") is a Maryland
corporation established to conduct real estate investment and development
activities. The Company was originally formed on January 21, 1998 as a
Massachusetts corporation and reincorporated (through a merger) in Maryland on
March 17, 1998. We are headquartered in Boston, Massachusetts and have a
regional office in Los Angeles, California. In 1999, we qualified as a real
estate investment trust (a "REIT") under the Internal Revenue Code of 1986, as
amended. We are the sole General Partner of Beacon Capital Partners, L.P. (the
"Operating Partnership").

    At December 31, 1999, we owned, directly or through a joint venture, 26
operating properties, consisting of 43 buildings and approximately 3.5 million
square feet. As of December 31, 1999, the properties were 93% leased. We also
have an approved development plan in Cambridge, Massachusetts to construct
approximately 600,000 square feet of office and laboratory space. We are also
part of a joint venture that is developing two office/R&D buildings in
Sunnyvale, California. In addition, we are part of a joint venture that is
developing a high-rise building in Seattle, Washington. On October 1, 1999, we
established Beacon Capital Strategic Partners, L.P. ("BCSP"), a private real
estate limited partnership. BCSP will be our exclusive real estate investment
vehicle for a period of up to two years from October 1, 1999.

    Since our inception, we have made distributions to our unitholders and
stockholders. We have paid two cash dividends and have also distributed our
interests in three voting trusts established to hold stock of companies in which
we have made investments. The following chart summarizes these distributions.
The numbers in the chart assume you have held 1,000 shares of common stock of
the Company since March 1998. If you did not hold any common stock on the date
of record for each of the distributions of the interests in the voting trusts,
you would not receive an interest in the relevant voting trust and will not

                                       3
<PAGE>
receive any distributions made in respect of that particular voting trust. An
interest in each of the voting trusts is the equivalent to one share of the
underlying securities held by that specific voting trust.

    Note 1: The Wyndham dividend is paid quarterly, partially in cash and
partially in paid in kind shares. The cash portion of the dividend is based on a
formula that keeps the cash dividend flat over the first six years. As defined
in the Certificate of Designation, "Cash Percentage" means, as to any date, the
amount calculated on the basis of the following formula (expressed as a
percentage), with the dividend payment period ("DPP") referring to the number of
dividend payment dates that have occurred prior to such date: 73,125/(7,000,000
times 1.024375 raised to the power of DPP (i.e., 1.024375(DPP)), plus
3,000,000).

RECENT EVENTS

    On May 1, 1998, we acquired a 970,000 square foot, eleven building portfolio
in Cambridge, Massachusetts known as The Athenaeum Portfolio for $195 million
including the assumption of approximately $69.1 million of first mortgage debt.
Two limited liability companies hold title to these properties. On May 20, 1998
we formed a joint venture with PW Acquisitions IX, LLC (an affiliate of
PaineWebber). Under the joint venture agreement, each party has a 50% interest
in the master limited liability company that controls the two limited liability
companies holding title to the properties.

    On June 24, 1998, we purchased a four-building complex known as Technology
Square and an adjacent building known as The Draper Building, consisting of
1,026,000 square feet located in Cambridge, Massachusetts. We paid approximately
$71.6 million in cash and issued approximately $51.4 million of Operating
Partnership units for the properties. In 1999, we began renovation and releasing
of two of the buildings and razed one building. We commenced a new development
plan to construct approximately 600,000 square feet of additional office and
laboratory space. Construction of the first building (176,000 square feet) has
begun and we currently expect it to be completed in the second quarter of 2001.

    The Draper Building is 100% leased to The Charles Stark Draper Laboratory,
Inc. ("Draper") on a long-term lease which expires on October 19, 2001. The
lease contained extension options through October 19, 2051. The lease states
that the first extension option was "to be exercisable by notice from Tenant to
Landlord given not later than the end of the 23rd year of the Term [October 19,
1999]." All subsequent extension options were only exercisable if Draper had
exercised its first extension option. We did not receive a notice from Draper
stating that it was exercising its extension option under the lease. The lease
also contains an option to acquire The Draper Building and a right of first
offer to acquire The Draper Building, each under certain circumstances.

    The extension options in the lease provided for fixed rental rates which
were substantially below the current market rate. Prior to the occurrence of the
event described above, we had valued The Draper Building under the assumption
that Draper would exercise its extension options. We do not believe that this
assumption is still warranted.

    On July 1, 1998, we acquired the Dallas Office and Industrial Portfolio, a
1,335,000 square foot portfolio of seven office properties and seven research &
development properties located in suburban Dallas, Texas. The total
consideration was $91.2 million, including the assumption of approximately $21.7
million of first mortgage debt.

    On August 9, 1998, we executed a joint venture agreement with Mathilda
Partners LLC, an affiliate of Menlo Equities (a California based developer) to
develop two Class A office/R&D buildings in Sunnyvale, California known as
Mathilda Research Centre. Construction has commenced and we currently expect to
complete the first building in June 2000 and the second building in June 2001.
Both buildings are 100% pre-leased to Juniper Networks, Inc.

    On September 1, 1998, we executed a joint venture agreement with HA L.L.C.,
an affiliate of Martin Smith Real Estate Services (a Seattle based real estate
company) to develop a 19-story, Class A office/retail and residential high-rise
building in downtown Seattle, Washington known as Millennium Tower. Construction
has begun and we currently expect it to be completed in the fourth quarter of
2000.

    On September 30, 1998 and October 8, 1999, we invested an aggregate of
$11 million to acquire preferred stock in Cypress Communications, Inc.
("Cypress"), a company which provides bundled communications services to tenants
in multi-tenant commercial buildings. On January 5, 2000, we distributed all of
this stock to our stockholders and unitholders subject to the terms of a voting
trust. On February 10, 2000, Cypress successfully completed its initial public
offering. See --"Item 7. Investing Activities".

    On June 30, 1999, we acquired 215 Fremont Street, a 299,000 square foot
building located in the South Financial District of San Francisco, California.
The purchase price was $33.5 million. We intend to

                                       5
<PAGE>
expand and fully redevelop the property into Class A office space. On
October 25, 1999, we transferred the property to one of our affiliates, BCSP,
and we were reimbursed for all costs incurred to date associated with the
acquisition, redevelopment, and carrying of the property.

    On June 30, 1999, we invested approximately $102.9 million to acquire
1,050,000 shares of preferred stock of Wyndham International, Inc. ("Wyndham").
On June 30, 1999, we distributed this stock to our stockholders and unitholders
subject to the terms of a voting trust. Subsequent to June 30, 1999, we
purchased approximately 57,578 of the Wyndham voting trust interests for an
aggregate price of approximately $5.3 million.

    On July 1, 1999, we invested approximately $44.1 million to acquire 450,000
shares of preferred stock of Wyndham. On October 29, 1999, we transferred
244,340 of these Wyndham preferred shares to Beacon Lodging, Inc., a
Massachusetts corporation ("Beacon Lodging"). The voting common stock of Beacon
Lodging is controlled by Messrs. Leventhal and Fortin. We own approximately 99%
of the economic interests in Beacon Lodging. On December 9, 1999, Wyndham
completed a rights offering to its current common shareholders and redeemed
approximately 8,399 shares of preferred stock held by us at a price of
approximately $0.9 million.

    On July 13, 1999, we purchased Fort Point Place, a four-building 335,000
square foot office and warehouse property located in the Boston, Massachusetts
South Boston Waterfront District for aggregate consideration of approximately
$24.3 million. We plan to redevelop the warehouse buildings for residential use.
See --"Item 3. Legal Proceedings".

    On October 1, 1999, we completed the initial closing for BCSP, a real estate
limited partnership, of which BCP Strategic Partners, LLC, our wholly owned
subsidiary, is the General Partner. Subsequent to October 1, 1999, we completed
additional closings and as of March 28, 2000, (the BCSP final closing date),
equity commitments totaled $287.5 million, of which our equity commitment was
$57.5 million. The commitments are from various endowments, foundations, pension
funds and other institutional investors. BCSP will be our exclusive real estate
investment vehicle for a period of up to two years.

    On November 12, 1999, we invested $8 million to acquire preferred stock in
CO Space, Inc., ("CO Space") a company that provides co-location space for data
storage, telecommunication carriers, and web-hosting applications. On March 24,
2000, we distributed all of this stock to our stockholders and unitholders
subject to the terms of a voting trust.

    On January 28, 2000, we announced a share repurchase program of up to
$30 million of our common shares over the next six months. The timing and size
of the repurchases are subject to market conditions, stock prices and our cash
position and requirements. As of March 28, 2000, no repurchases have been
executed.

INVESTMENT STRATEGIES

    Our real estate investment strategy will be implemented through BCSP, a real
estate limited partnership, which we established in October 1999. For a period
of up to two years from October 1, 1999, BCSP will serve as our exclusive real
estate investment vehicle. In addition, the Company may elect to make
investments in non real estate entities. We have committed to invest 20% of the
total capital in BCSP and will serve as its General Partner. The investment
strategy of BCSP is consistent with the strategy that has been employed by the
Company since its inception.

    Our investment activity is focused in the following types of real
estate-related assets: (i) value-added repositionings and discounted purchases;
(ii) development and re-development; (iii) multiple-property portfolios; (iv)
joint ventures and strategic partnerships; and (v) real estate companies and
real estate-related businesses.

                                       6
<PAGE>
    (i) VALUE-ADDED REPOSITIONINGS AND DISCOUNTED PURCHASES. We target
investments in under-utilized or poorly capitalized single assets and portfolios
that may be recapitalized on advantageous terms and repositioned with the
expectation of returns greater than those that could be achieved by acquiring a
stabilized property. These investments may include the purchase of the property
at a discount to replacement cost or the purchase of the underlying debt thereon
often at a discount to face value. In today's dynamic real estate industry with
an ever-changing and cyclical economy and changing demographic characteristics,
there generally will be opportunities to take better advantage of well-located
and structurally sound properties. Opportunities may involve substantial
rehabilitation or re-development and ground-up development where market
conditions warrant new construction.

    (ii) DEVELOPMENT AND RE-DEVELOPMENT. On a selected basis, we target
investments requiring strategic ground-up development or re-development of
existing properties that can benefit from repositioning. We expect to seek out
opportunities where market vacancy rates and market rents justify new
construction and where job growth will support new demand for office, laboratory
and industrial space.

    (iii) MULTIPLE PROPERTY PORTFOLIOS. We target real estate acquisitions
resulting from corporate divestitures from users, financial institutions, and
other non-strategic and inefficient owners of real estate. We believe that the
trend from private to public ownership is motivating many institutions to
liquidate their privately-held real estate portfolios.

    (iv)  JOINT VENTURES AND STRATEGIC PARTNERSHIPS. We expect to continue to
enter into, or acquire interests in, joint ventures or strategic partnerships as
a way to leverage both capital and expertise.

    (v) REAL ESTATE COMPANIES AND REAL ESTATE-RELATED BUSINESSES. We also target
investments in real estate companies and businesses with a real estate
component. Opportunities in this target area include public and private
companies, and generally fall into three types of companies: (a) real estate
ownership companies, including REITs and non-REIT ownership companies,
homebuilders and other development companies; (b) real estate service companies,
such as management or brokerage companies; and (c) businesses with a strategic
dependence on real estate. We intend to invest in private placements of common
stock or other securities convertible into common stock. When we identify strong
management teams and growth prospects, we may provide growth capital to such
companies and may recapitalize over-leveraged or other poorly-capitalized
companies.

    Although our primary emphasis has been on the acquisition of the
above-described categories of real estate-related assets, future acquisitions
also may include other assets. When and if such investments are made, they will
not be the principal focus of our investment strategy.

CORPORATE STRATEGY

    Given current market conditions, we do not believe that it is in the best
interest of the Company to complete an initial public offering in the
foreseeable future. We expect to generate cash for purposes of making
distributions to shareholders, or to repurchase our Common Stock, by refinancing
or selling assets. We intend to continuously evaluate our opportunities for
refinancing or selling assets with the intention of completing such transactions
upon advantageous terms. No assurances can be made, however, that we will be
able to complete the refinancings or sales of assets upon favorable terms, if at
all.

ENVIRONMENTAL MATTERS

    We do not expect any costs associated with environmental issues at our
properties to have a material adverse effect on the Company.

COMPETITION

    We compete in the leasing of office, laboratory and industrial space with a
considerable number of other realty concerns, some of which may have greater
marketing and financial resources than us.

                                       7

SEASONALITY

    The Company's office, laboratory and industrial properties have not
traditionally experienced significant seasonality.

EMPLOYEES

    As of December 31, 1999, we had 31 full time employees.

RISK FACTORS

    In addition to other information contained in or incorporated by reference
in this Form 10-K, you should carefully consider the following risk factors
before investing in our Common Stock:

ECONOMIC AND BUSINESS RISKS

WE DEPEND ON KEY PERSONNEL WHOSE CONTINUED SERVICE IS NOT GUARANTEED

    We believe that our success depends in large part upon the experience of
Alan M. Leventhal, Lionel P. Fortin and other members of our senior management
whose continued service is not guaranteed. We have executed employment and
non-competition agreements with Messrs. Leventhal and Fortin, but we cannot
guarantee that these agreements are judicially enforceable. If we lost the
services of either Mr. Leventhal or Mr. Fortin, our operations might suffer.
Until we found a qualified replacement, we would be less capable of:

    --  obtaining real estate investment opportunities;

    --  capitalizing upon relationships in the real estate industry; and

    --  structuring and executing potential investments.

    We cannot assure you that we would replace Mr. Leventhal or Mr. Fortin with
someone who has equivalent knowledge and experience. We may not be able to
successfully recruit additional personnel. Any additional personnel we do
recruit may not have the requisite skills, knowledge or experience necessary or
desirable to enhance our incumbent management. In addition, we do not currently
maintain key-man life insurance on any of our executive officers.

WE MAY NOT SUCCESSFULLY IMPLEMENT OUR GROWTH STRATEGY

    ADDITIONAL FINANCING MAY NOT BE AVAILABLE

    Our ability to implement our growth strategy depends on access to the
capital necessary to invest in assets. If we fail to obtain the necessary
capital, our ability to acquire assets could suffer.

    WE MAY FAIL TO EFFECTIVELY MANAGE OUR RAPID GROWTH

    To successfully implement our acquisition strategy, we must integrate
acquired assets into our existing operations. As such, we must consolidate
functions and integrate the departments, systems and procedures of the acquired
assets with our operations. Integration presents a significant challenge to us.
If we fail to effectively integrate new assets, our results of operations and
financial condition could suffer.

    COMPLEX ACQUISITIONS HAVE A GREATER RISK OF FAILURE

    We intend to acquire multiple assets in a single transaction. This technique
reduces acquisition expenses and provides us with operating leverage. However,
portfolio acquisitions are more complex than single-property acquisitions. The
risk that a multiple property acquisition will not close is greater than in a
single-property acquisition. In addition, the cost of a failed portfolio
acquisition closing is greater than the

                                       8
<PAGE>
cost of a failed single-property acquisition closing. If one of our portfolio
acquisition closings failed, we would incur a charge against our earnings for
the costs related to that failed acquisition.

    Our portfolio acquisitions may result in the acquisition of assets located
in geographically dispersed markets that are geographically removed from our
principal markets. This geographic diversity could strain our ability to manage
such dispersed assets. In addition, a seller may demand that we purchase a group
of properties together despite one or more failing to meet our investment
criteria. If this were to occur, we would attempt to either:

    --  make a joint bid with another buyer; or

    --  purchase the portfolio with the intent to subsequently dispose of those
        assets which do not meet our investment criteria.

This strategy presents two problems:

    --  If we participate in a joint bid, the other buyer may default on its
        obligations and increase the risk that the acquisition may not close.

    --  If we intend to dispose of assets that we do not wish to own, there can
        be no assurance as to how quickly we could sell or exchange such assets
        or the terms on which they could be sold or exchanged.

    DEVELOPMENT OR REDEVELOPMENT OF ASSETS IS COSTLY AND MAY NOT YIELD ECONOMIC
     BENEFITS

    We intend to develop and construct real estate-related assets in accordance
with our development and underwriting policies. Risks associated with such
development and construction activities include the risks that:

    (i) we may abandon development opportunities after expending resources to
       determine feasibility;

    (ii) construction costs may exceed original estimates;

    (iii) occupancy rates and rents at a newly completed property may not be
       sufficient to make the project profitable;

    (iv) financing may not be available on favorable terms;

    (v) construction and lease-up may not be completed on schedule and thus
       result in increased debt service expenses and construction costs;

    (vi) we may be unable to obtain (or be delayed in obtaining) all necessary
       zoning, land-use, building, occupancy, and other required governmental
       permits and authorizations;

    (vii) since new projects require a substantial portion of management's time
       and attention, management may be significantly preoccupied with these new
       projects (regardless of whether or not they are ultimately successful);

    (viii)permanent financing may not be available or may only be available on
       unfavorable terms; and

    (ix) our losses may exceed our investment return if the project is
       unsuccessful.

CONFLICTS OF INTEREST EXIST BETWEEN THE COMPANY AND OTHERS

    CONFLICTS RELATING TO THE OPERATING PARTNERSHIP

    The Company (as the General Partner of the Operating Partnership) will have
fiduciary obligations to the limited partners of the Operating Partnership that
may conflict with the interests of our stockholders. In addition, the limited
partners will have the right to vote:

                                       9
<PAGE>
    --  as a class on certain amendments to the Operating Partnership agreement;
        and

    --  individually to approve certain amendments that would adversely affect
        their rights.

    The limited partners' voting rights may be exercised in a manner that
conflicts with your interests if you should acquire shares of our Common Stock.

    Under the terms of the Operating Partnership agreement, the General Partner
(currently the Company) must obtain approval from the partners of the Operating
Partnership to engage in certain transactions if, pursuant to the Maryland
General Corporate Laws or our organizational documents, a transaction would
require a vote of our stockholders. As such, approval of the stockholders and
the partners would be necessary before certain transactions could be
consummated. The partners' interest in approving any such transaction may or may
not align with the stockholders' interest in approving the transaction. Thus,
the partners may prevent consummation of a transaction which the stockholders
believe is in their best interest.

    CONFLICTS RELATING TO THE BCP SISTER CORP.

    Certain of our officers and directors may also serve as officers or
directors of a BCP Sister Corp. (if and when formed). This may create
conflicting demands on the time of those officers and directors serving both the
Company and the BCP Sister Corp. If (as expected) ownership of the BCP Sister
Corp. and the Company ultimately differ, conflicts of interest may develop. We
cannot assure you that conflicts between the Company and the BCP Sister Corp.
will not arise concerning short-term or long-term business plans, investment
strategy, geographic concentration or services provided.

    In addition, provisions in the BCP Sister Corp.'s formation documents are
expected to:

    (i) enable the BCP Sister Corp. to enter into transactions with the Company
       to the extent deemed beneficial by their respective boards of directors;
       and

    (ii) generally prohibit the BCP Sister Corp. from engaging in activities or
       making investments appropriate for a REIT unless:

    --  the Company is first given the opportunity to engage in the activity or
        make the investment; and

    --  the Company elects to not engage in the activity or make the investment.

    We cannot assure you that any agreement will prevent conflicts between the
Company and the BCP Sister Corp. regarding which person or entity may pursue
potential business opportunities (if any).

    CONFLICTS RELATING TO THE INCENTIVE RETURN

    Our Long-Term Incentive Plan consists of a convertible unit issued to Beacon
Capital Participation Plan ("BCPP") on March 16, 1998. BCPP is an entity owned
and controlled by our management. BCPP was established to receive the
convertible unit of the Operating Partnership. Messrs. Leventhal and Fortin
control and own equity interests in BCPP and certain members of our management
also hold minority interests in BCPP.

    If we meet certain earnings goals, the convertible unit will convert into a
number of incentive units of limited partnership interest in the Operating
Partnership ("Incentive Units"). The earnings goals are measured at the end of
the three-year period following January 1, 1999. The value of the Incentive
Units will be equal to the Incentive Return. The Incentive Return is calculated
based on the growth of the Company's Funds from Operations above a specified
benchmark (measured at the end of a specified period).

                                       10
<PAGE>
    Recently, we adopted a new Management Incentive Plan (the "New Plan"), which
is being submitted to our stockholders for ratification at our 2000 Annual
Meeting of Stockholders. The New Plan contemplates that BCPP will receive its
Incentive Return only after our investors have received a return of their
capital with a ten percent per annum cumulative compounded return. For purposes
of determining the amounts of incentive distributions payable under the New
Plan, our June 1999 distribution of interests in the voting trust formed to hold
shares of Wyndham's preferred stock (the "Wyndham Preferred Stock"), the
January 2000 distribution of interests in the voting trust formed to hold shares
of Cypress' preferred stock and the March 2000 distribution of interests in the
voting trust formed to hold shares of CO Space's preferred stock would NOT be
treated as distributions to the partners of the Operating Partnership. Instead,
the shares held by the voting trusts would be treated as if held by the
Operating Partnership until such time as those shares were actually distributed
to the beneficial holders of the interests in the voting trusts, at which time
all of the partners of the Operating Partnership would be treated as receiving a
pro rata distribution from the Operating Partnership in the amount of the then
value of the shares distributed from a voting trust (regardless of the extent to
which the investors continue to hold interests in a voting trust).
Payment-in-kind dividends of additional shares of Wyndham Preferred Stock
received by the Wyndham voting trust and retained in the trust in accordance
with the terms of the voting trust agreement also would be treated as
distributed pro rata to the partners of the Operating Partnership in accordance
with their partnership interests when ultimately distributed out of the Wyndham
voting trust. Similarly, cash or other amounts received by a voting trust would
be treated as a pro rata distribution to the partners of the Operating
Partnership in accordance with their units at such times that such cash or other
amounts are distributed out of the voting trust to the holders of beneficial
interest in the voting trust. Similar rules would apply to any additional voting
trust, or similar arrangement established by the Company. If adopted, purchasers
of our common stock who do not simultaneously purchase a proportionate amount of
the shares held through these three voting trusts might not realize all of the
economic benefits upon which management's compensation will be calculated.

    The New Plan was designed to align the interests of our management with the
interests of our stockholders by having members of management purchase an equity
interest in BCPP. However, we cannot assure you that conflicts will not arise
between management's interests and stockholders' interests.

    POLICIES WITH RESPECT TO CONFLICTS OF INTEREST

    We intend to adopt policies designed to eliminate or minimize conflicts of
interest. One such policy would require that all transactions in which officers
or directors have a conflicting interest must be approved by a majority of our
Independent Directors. However, we cannot assure you that any policy will
successfully minimize or eliminate conflicts of interest. If our policies fail,
decisions could be made that do not fully reflect the stockholders' interests.

LEVERAGE CAN REDUCE INCOME AVAILABLE FOR DISTRIBUTION TO STOCKHOLDERS

    We intend to leverage our assets by borrowings through bank credit
facilities, mortgage loans on real estate and other borrowings. Our return on
investments and cash available for distribution to stockholders might suffer by
changes in market conditions which cause the cost of the financing to exceed the
income from the asset. We have obtained an interim financing facility that bears
interest at a variable rate. If we do not engage in a successful hedging
strategy with respect to this financing, an increase in the interest rate
payable on such financing could cause higher debt payments and could materially
adversely affect liquidity and results from operations.

    Leverage creates an opportunity for increased returns on equity, but also
creates risks. For example, debt service payments can reduce the net income
available for distributions to stockholders. We cannot assure you that we will
be able to meet our debt service obligations and, to the extent that we cannot,
we may lose some or all of our assets to foreclosure or sale to satisfy our debt
obligations. Interest rate changes can affect our income by affecting:

                                       11
<PAGE>
    --  the spread between the income on our assets and interest-bearing
        liabilities;

    --  the value of our interest-earning assets; and

    --  our ability to realize gains from the sale of assets.

    We have adopted guidelines to maintain a debt to total market capitalization
ratio not in excess of 60%. This policy enables us to incur additional
indebtedness as the value of our assets increases even though there has not
necessarily been a corresponding increase in our ability to service our
indebtedness. For purposes of this policy, our debt to market capitalization
ratio is calculated as:

    --  our proportionate share of total consolidated and unconsolidated debt as
        a percentage of the market value of our assets; plus

    --  our proportionate share of total consolidated and unconsolidated debt.

    Our Charter and Bylaws do not limit the amount of indebtedness we can incur.
Accordingly, our Board of Directors could alter or eliminate this policy. They
would do so, for example, if it were necessary for us to continue to qualify as
a REIT.

RISKS ASSOCIATED WITH HEDGING INVESTMENTS AND INVESTMENTS IN DERIVATIVES

    Interest rate changes may adversely affect our investments. Interest rates
are highly sensitive to many factors, including:

    --  governmental, monetary and tax policies;

    --  domestic and international economic and political considerations; and

    --  other factors beyond our control.

    We may employ a hedging strategy to limit the effects of interest rate
changes on our operations, including engaging in interest rate swaps, caps,
floors and other interest rate exchange contracts. Our use of these types of
derivatives to hedge our assets and liabilities carries certain risks, such as:

    --  losses on a hedge position may reduce the funds available for
        distribution to stockholders; and

    --  losses on a hedge position may exceed the amount invested in such
        instruments.

    We have no formal policy with respect to hedging investments or investments
in derivatives. There is no perfect hedge for any investment, and a hedge may
not perform its intended use of offsetting losses on an investment. Moreover, we
are exposed to the risk that the counter parties with whom we trade may stop
making markets and quoting prices in such instruments. If this happened, we
would be unable to enter into an offsetting transaction with respect to an open
position.

    Any losses incurred may be amplified if the hedging vehicle moves more or
less than the price movement of the asset being hedged. We cannot assure you of
a correlation between price movements in a hedging vehicle and an asset being
hedged. This presents the risk that both the hedging vehicle and the hedged
asset may decline in value at the same time. In addition, if a party to a
hedging transaction defaults, we may only have contractual remedies (which may
be limited by bankruptcy, insolvency or similar laws) pursuant to the agreement
related to the transaction. Our profitability may be adversely affected during
any period as a result of changing interest rates or due to losses incurred in
hedging transactions. This could possibly result in a material adverse impact on
our liquidity and results from operations.

THE COMPANY'S INSURANCE WILL NOT COVER ALL LOSSES

    We intend to maintain comprehensive insurance on each of our significant
assets. This coverage includes liability and fire and extended coverage, in
amounts sufficient to permit the replacement of the assets in the event of a
total loss, subject to applicable deductibles. We will endeavor to obtain
coverage of

                                       12
<PAGE>
the type and in the amount customarily obtained by owners of similar properties.
However, certain losses are generally uninsurable or not economically insurable:

    --  catastrophic losses such as fire, flood and hurricane;

    --  economic conditions such as inflation;

    --  legal conditions such as changes in building codes and ordinances;

    --  environmental considerations; or

    --  other conditions or considerations which may make it infeasible to use
        insurance proceeds to replace an asset if it is damaged or destroyed.

    Under such circumstances, the insurance proceeds we received might not be
adequate to restore our economic position with respect to the affected asset.

PROPERTY TAXES DECREASE RETURNS ON REAL ESTATE

    Each of our assets will be subject to real and (in some instances) personal
property taxes. The real and personal property taxes on our assets may increase
or decrease as property tax rates change or as the assets are assessed or
reassessed by taxing authorities. If property taxes on our investments increase,
our cash available for distribution to our stockholders would be adversely
affected.

COMPLIANCE WITH AMERICANS WITH DISABILITIES ACT AND OTHER CHANGES IN
GOVERNMENTAL RULES AND REGULATIONS MAY BE COSTLY

    Under the Americans with Disabilities Act of 1990 (the "ADA"), all public
properties are required to meet certain federal requirements related to access
and use by disabled persons. Properties we acquire may not be in compliance with
the ADA. If a property is not in compliance with the ADA, we will be required to
make modifications to such property to bring it into compliance. If we fail to
comply, we face the possibility of an imposition of fines or an award of damages
to private litigants. In addition, we could face changes in governmental
rules and regulations or enforcement policies affecting the use and operation of
the properties, including changes to building codes and fire and life-safety
codes. If we were required to make substantial modifications to our properties
to comply with the ADA or other changes in governmental rules and regulations,
our ability to make expected distributions to stockholders could be adversely
affected.

ADVERSE EFFECT ON RESULTS OF OPERATIONS DUE TO POSSIBLE ENVIRONMENTAL
  LIABILITIES

    Our operating costs may be affected by the obligation to pay for the cost of
complying with existing and future environmental laws, ordinances and
regulations. Environmental problems could materially impair the value of assets.
Under various federal, state and local environmental laws, ordinances and
regulations, a current or previous owner or operator of real property may be
liable (often regardless of knowledge or responsibility) for the costs of
removal or remediation of hazardous or toxic substances releases at its
property. These costs could be substantial. The presence of such substances (or
the failure to properly remediate the contamination) may materially and
adversely affect the owner's ability to borrow against, sell or rent the
affected property.

    Persons who arrange for the transportation, disposal or treatment of
hazardous or toxic substances may also be liable for the costs of removal or
remediation of such substances at the disposal or treatment facility, whether or
not such facility is or ever was owned or operated by such person. In addition,
certain environmental laws and common law principles impose liability for
releases of hazardous materials into the environment, including
asbestos-containing materials ("ACMs"). These laws may impose liability for
release of ACMs and may provide for third parties to seek recovery from owners
or operators of real

                                       13
<PAGE>
properties for personal injury associated with exposure to released ACMs or
other hazardous materials. In connection with our ownership and operation of
certain assets, we may potentially be liable for such costs.

    Environmental laws may also impose restrictions on the use or transfer of
property and on the manner in which a business is operated. These restrictions
may require expenditures. We may be liable for any such costs in connection with
certain of our assets. In addition, the cost of defending against claims of
liability or remediating contaminated property and the cost of complying with
such environmental laws could materially adversely affect our results of
operations and financial condition.

    In connection with the acquisition of Real Estate-Related Assets, we intend
to obtain Phase I environmental site assessments ("ESAs") prepared by qualified
independent environmental engineers. The purpose of ESAs is to identify
potential sources of contamination for which the Assets may be responsible and
to assess the status of environmental regulatory compliance. It is possible,
however, that these ESAs will not reveal all environmental liabilities or that
such assets may be subject to material environmental liabilities of which we are
unaware.

BCP SISTER CORP. WILL HAVE SEPARATE FINANCING, WHICH MAY NOT BE AVAILABLE

    We anticipate that the BCP Sister Corp. (if and when formed) will obtain its
own financing, separate from that of the Company. We cannot assure you that such
financing will be readily available or (if available) that it will be on terms
acceptable to the BCP Sister Corp. In addition, to the extent that the BCP
Sister Corp. should default under such financing, we cannot assure you that it
would be able to obtain sufficient financing to cure such default. We also
cannot ascertain the full impact of such default on the Company.

INVESTMENT ACTIVITY RISKS

APPROPRIATE INVESTMENTS MAY NOT BE AVAILABLE

    Although we may invest in other assets as opportunities arise, we intend to
focus primarily on acquiring real estate-related assets consistent with our
investment strategy. We cannot assure you that:

    --  we will identify assets that meet our investment criteria;

    --  we will be successful in acquiring any assets that may be identified; or

    --  acquired assets will produce a return on our investment.

    We will have broad authority to invest in assets consistent with our
investment strategy. We may invest in highly-leveraged assets, which may
increase the likelihood of a loss of our assets through foreclosure. No
assurance can be made that our decisions in this regard will result in a profit
for the Company. Investment in real estate is a highly competitive business and
the acquisition of assets is often based on competitive bidding. Consequently,
our inability to identify appropriate assets may have an adverse effect on our
results of operations and hinder our growth rate.

REAL ESTATE IS ILLIQUID AND VALUE IS DEPENDENT ON CONDITIONS BEYOND THE
  COMPANY'S CONTROL

    We expect to invest in assets which may be subject to varying degrees of
risk generally incident to the ownership of real property. Real estate
investments are relatively illiquid. Our ability to vary investments in response
to changes in economic and other conditions will be limited. We cannot assure
you that the fair market value of any assets we acquire will not decrease in the
future. The underlying value of our assets, our income and our ability to make
distributions to stockholders are dependent upon our ability to operate our
assets in a manner sufficient to maintain or increase revenue in excess of
operating expenses and debt service. Our revenue may be adversely affected by
the following:

    --  adverse changes in national or local economic conditions;

                                       14
<PAGE>
    --  competition from other properties offering the same or similar services;

    --  changes in interest rates and in the availability, cost and terms of
       mortgage funds;

    --  impact of present or future environmental legislation and compliance
       with environmental laws;

    --  ongoing need for capital improvements (particularly in older
       structures); changes in real estate tax rates and other operating
       expenses; adverse changes in governmental rules and fiscal policies;

    --  civil unrest;

    --  acts of God, including earthquakes, hurricanes and other natural
       disasters (which may result in uninsured losses);

    --  acts of war;

    --  adverse changes in zoning laws; and other factors which are beyond our
       control either in whole or in part.

WE MUST COMPETE WITH OTHER COMPANIES FOR ACQUISITIONS

    We intend to invest in real estate industry sectors which are highly
competitive. We may compete for assets with entities which have substantially
greater economic and personnel resources than the Company and better
relationships with sellers of assets, lenders and others. These entities may
also generally be able to accept more risk than we can prudently manage.
Competition may generally reduce the number of suitable prospective assets
offered to us and increase the bargaining power of property owners seeking to
sell, thereby increasing prices.

WE MUST BE ABLE TO PAY OFF OUR FINANCING

    We are subject to the risks normally associated with debt financing. This
includes the risk that our cash flow will be insufficient to meet required debt
service. In addition, we may be unable to refinance our existing indebtedness.
If we do refinance, the terms of the financing may not be as favorable as the
existing indebtedness terms.

REAL ESTATE INVESTMENT RISKS

    Real property investments have varying degrees of risks. Our cash flow and
ability to make distributions to stockholders will be adversely affected if our
assets do not generate revenues sufficient to meet operating expenses, including
debt service and capital expenditures. An asset's revenues and value may be
adversely affected by the following:

    --  the general economic climate; the local economic climate;

    --  local real estate conditions;

    --  the ability of the owner to provide adequate management, maintenance and
       insurance; and

    --  increased operating costs.

    Certain significant expenditures associated with an equity investment are
generally not reduced when circumstances cause a reduction in income from the
investment. These include mortgage payments, real estate taxes, or insurance and
maintenance costs. In addition, we face numerous competitors for development and
acquisitions of properties which may have greater resources than the Company.

RISKS RELATING TO OUR INVESTMENT IN BEACON CAPITAL STRATEGIC PARTNERS, L.P.

    Pursuant to the limited partnership agreement of BCSP, we must make all of
our real estate investments through BCSP until the earlier of October 1, 2001 or
when 85% of the capital has been

                                       15
<PAGE>
invested. We have committed to invest $57.5 million in BCSP. Our investment in
BCSP entails risks including the following:

    THE TERMS OF OUR INVESTMENT POTENTIALLY REDUCE POTENTIAL PROFITS TO THE
     COMPANY FROM INDIVIDUAL INVESTMENTS

    We will only be entitled to a pro rata portion of the profits of BCSP which
are distributed to limited partners, based upon the proportion that our
investment in BCSP as a limited partner bears to the aggregate capital
commitments of all limited partners in BCSP. Since individual real estate
investment opportunities are often of fixed size, the Company may have to share
profits of individual investments with its partners in BCSP which, absent its
arrangement with BCSP, it might otherwise secure for itself by making a larger
investment on its own behalf than is represented by its share of BCSP's
investment.

    WE ARE RESTRICTED FROM MAKING CERTAIN TYPES OF INVESTMENTS

    A wholly-owned subsidiary of the Company is the general partner of BCSP and,
as general partner, is entitled to a portion of the profits of BCSP. While our
wholly-owned subsidiary, as general partner, exercises investment control over
BCSP in most instances, BCSP's limited partnership agreement places certain
restrictions on the general partner which may be waived, with respect to a
particular investment, by limited partners in BCSP representing a voting
interest of the limited partners in excess of 50% (not including any Beacon
affiliate). These restrictions include the following:

    --  the general partner shall not make an investment if the amount of such
       investment would exceed 25% of the aggregate capital commitments for a
       period of more than 180 days after such investment has been made, unless
       the general partner obtains the prior approval of the board of advisors
       of BCSP for such investment; provided that at no time may the amount of
       capital invested in any single investment exceed 35% of the aggregate
       capital commitments;

    --  with respect to an investment in an operating company, the general
       partner shall not make such an investment if the amount invested in all
       such operating companies would exceed 20% of the aggregate capital
       commitments divided by 35%;

    --  with respect to an investment in new development, the general partner
       shall not make such an investment if the amount invested in all such new
       development would exceed 20% of the aggregate capital commitments of
       BCSP; and

    --  the general partner shall not make an investment in any real estate
       assets located outside of the United States, or in companies organized,
       headquartered or having substantially all of their assets outside of the
       United States.

In addition, unless waived as set forth above, BCSP may not:

    --  engage in speculative investment activity involving derivatives that
       would subject BCSP to unlimited exposure;

    --  make any investments in an entity that invests primarily in oil or gas
       development or in any collective investment entity whose constituent
       documents provide for the payment of incentive compensation based on the
       investment returns of the collective investment entity to a person other
       than BCSP, unless the general partner or BCSP has the power to direct the
       investment decisions of such collective investment entity or prevent
       investments from being made by such collective investment entity;

    --  make non-influence bearing investments in publicly traded securities if
       the amount invested in all such securities would exceed 5% of the
       aggregate capital commitments divided by 35%; or

                                       16
<PAGE>
    --  incur indebtedness if, immediately after giving effect to the incurrence
       of such indebtedness, the aggregate indebtedness of BCSP would exceed 65%
       of the sum of (a) the aggregate amount of all uncontributed capital
       commitments plus (b) the aggregate value of BCSP's investments,
       determined on the basis of the most recent valuations available.

    We would not face these restrictions if we were not obligated to make our
investments through BCSP. As a result, our arrangement with BCSP may prohibit us
from making investments that we might otherwise make absent such arrangement.

RISKS RELATED TO INVESTMENTS IN MORTGAGE LOANS

    Mortgage loan investments have certain risks that other types of investment
do not, including without limitation the following:

    COMMERCIAL MORTGAGE LOANS MAY INVOLVE A RISK OF LOSS

    Commercial mortgage loans have a high degree of risk because of a variety of
factors, including:

    --  the loans are dependent for repayment on successful operation of the
       mortgaged property and any tenant businesses operating on the property;

    --  the loans are usually non-recourse to the borrower;

    --  the loans have terms that include amortization schedules longer than
       stated maturity.

    --  the loan terms provide for balloon payments at stated maturity rather
       than periodic principal payments; and

    --  the value of the property underlying the loan can be affected
       significantly by the supply and demand in the market for that type of
       property.

    VOLATILITY OF VALUES OF MORTGAGED PROPERTIES MAY ADVERSELY AFFECT THE
     COMPANY'S MORTGAGE LOANS

    Commercial real estate values and the net operating income derived from the
property are subject to volatility and may be affected adversely by a number of
factors, including, but not limited to:

    --  national, regional and local economic conditions;

    --  local real estate conditions;

    --  changed or continued weakness in specific industry segments;

    --  general public perceptions of the safety, convenience, services and
       attractiveness of the property;

    --  willingness and ability of the property's owner to:

       (i) provide capable management,

       (ii) provide adequate maintenance,

       (iii) make capital expenditures and improvements, and

       (iv) provide leasing concessions;

    --  construction quality, age and design; and

    --  increases in operating expenses (such as energy costs).

                                       17
<PAGE>
    GENERAL DEFAULT RISKS

    With respect to our investments in mortgage loans, we face the risks of
borrower defaults, bankruptcies, fraud and special hazard losses (which are not
covered by standard hazard insurance). If a borrower defaults, we bear a risk of
loss of principal to the extent that the value of the collateral is less than
the amount due on the mortgage loan. In addition, failure to receive interest
payments because of borrower default could have a materially adverse effect on
our cash flow from operations. If a borrower declares bankruptcy, we face the
following risks:

    --  the bankruptcy court determines the value of the underlying collateral
       at the time of bankruptcy;

    --  the bankruptcy trustee may avoid the lien securing the mortgage loan;
       and

    --  the debtor-in-possession may avoid the lien securing the mortgage loan
       to the extent the lien is unenforceable under state law.

    If we have to foreclose a mortgage, the process can be expensive and
lengthy. These costs could adversely affect our anticipated return on the
foreclosed mortgage loan.

OUR MULTI-SECTOR INVESTMENT STRATEGY IS MORE COMPLICATED THAN A SINGLE-SECTOR
  INVESTMENT STRATEGY

    Our current strategy is to acquire assets in a variety of real estate
product-types within a variety of geographic locations. Initially, we will
emphasize office assets. Accordingly, we will be required to maintain expertise,
relationships and market knowledge across a broad range of product-types and
geographic regions.

    In addition, we face market conditions that affect each such product-type in
the various markets, including such factors as:

    --  local economic climate;

    --  business layoffs;

    --  industry slowdowns;

    --  changing demographics; and

    --  local supply and demand issues affecting each such market.

    Our multi-sector approach could require more management time, staff support
and expense than a company focused upon a single product-type in fewer
jurisdictions than contemplated by the Company.

GEOGRAPHICALLY CONCENTRATED ASSETS ARE VULNERABLE TO DOWNTURNS IN LOCAL ECONOMIC
  CONDITIONS

    The economic performance and value of our assets are subject to all of the
risks incident to the ownership and operation of real estate. These include the
risks normally associated with changes in national, regional and local economic
and market conditions. Such conditions can affect tenants' ability to make
rental payments. Our assets are located in seven markets--East Cambridge,
Massachusetts; South Boston, Massachusetts; San Francisco, California;
Sunnyvale, California; Dallas, Texas; Loudoun County, Virginia; and Seattle,
Washington. We have no limits on becoming more geographically concentrated.

    Local real estate market conditions may include a large supply of competing
space and competition for tenants, including competition based on:

    --  rental rates;

    --  attractiveness;

    --  location of property; and

                                       18
<PAGE>
    --  quality of maintenance, insurance and management services.

    Other factors may adversely affect the performance and value of an asset,
including:

    --  changes in laws and governmental regulations (including those governing
       usage, zoning and taxes);

    --  changes in interest rates; and

    --  availability of financing.

    If the assets do not generate sufficient income to meet operating expenses,
our income and ability to make distributions to stockholders may be adversely
affected.

NEW MARKETS MAY HAVE CONDITIONS UNLIKE OUR EXISTING MARKETS

    Although our management has historical experience with Real Estate-Related
Assets and other assets and investments in a variety of geographic areas of the
country, our expertise in those markets may not assist us in new markets. In
such event, we may be exposed to risks associated with:

    --  lack of market knowledge and understanding of the local economy;

    --  inability to access land and property acquisition opportunities;

    --  inability to obtain construction tradespeople;

    --  sudden adverse shifts in supply and demand factors; and

    --  unfamiliarity with local governmental procedures.

WE WILL NOT HAVE FULL CONTROL OVER INVESTMENTS MADE THROUGH PARTNERSHIPS AND
  JOINT VENTURES

    Instead of purchasing properties directly, we may invest as a partner or a
co-venturer. Partnership or joint venture investments may involve risks not
otherwise present, including:

    --  our partner or co-venturer might become bankrupt;

    --  our partner or co-venturer might at any time have economic or other
       business interests or goals which are inconsistent with our business
       interests or goals; and

    --  our partner or co-venturer may be in a position to take action:

       (i) contrary to our instructions or requests; or

       (ii) contrary to our policies or objectives, including our policy with
           respect to maintaining our qualification as a REIT.

    These investments may also have the potential risk of impasse on decisions
because neither we nor our partner or co-venturer would have full control over
the partnership or joint venture. We will seek to maintain sufficient control of
such partnerships or joint ventures to achieve our objectives. Our
organizational documents do not limit the amount of available funds which we may
invest in partnerships or joint ventures.

WE WILL NOT HAVE FULL CONTROL OVER INVESTMENTS MADE THROUGH SUBSIDIARIES

    The common stock of four of our subsidiaries, BCP Millennium Residential,
Inc., Cambridge Kendall SPC, Inc., Beacon Lodging, Inc. and Fort Point Place,
Inc. consists of two classes: voting and nonvoting. Of the voting common stock,
Messrs. Leventhal and Fortin hold 91% and the Operating Partnership holds 9%.
The Operating Partnership holds all of the nonvoting stock. The Operating
Partnership owns 99% of the economic interest in these subsidiaries and Messrs.
Leventhal and Fortin jointly own 1% of such

                                       19
<PAGE>
economic interest. As holders of 91% of the voting common stock,
Messrs. Leventhal and Fortin have the ability to elect the board of directors of
these subsidiaries. We are not able to elect the directors, which means that we
may not be able to influence the day-to-day decisions affecting these
subsidiaries. As such, the boards of directors of these subsidiaries may
implement business policies or decisions that would not have been implemented by
persons controlled by the Company and may be adverse to our interests and could
adversely impact our results of operations.

FOREIGN REAL PROPERTIES ARE SUBJECT TO CURRENCY CONVERSION RISKS AND UNCERTAINTY
  OF FOREIGN LAWS

    In addition to making investments in domestic assets, the Company may invest
in assets located outside the United States. Risks inherent in investing in real
estate located in foreign countries generally include:

    --  unexpected changes in regulatory environments;

    --  longer accounts receivable payment cycles;

    --  potentially adverse tax consequences; and

    --  the burden of complying with a wide variety of foreign laws.

    Moreover, investments in foreign Assets may be exposed to the risk of
fluctuations in the foreign exchange rates between the US dollar and the
currency in which a transaction is conducted.

LEGAL AND TAX RISKS

TAX RISKS

    We intend to operate in a manner that will enable us to qualify as a REIT
for federal income tax purposes. Although we do not intend to request a ruling
from the Internal Revenue Service (the "IRS") as to our REIT status, we received
(in connection with the original Registration Statement) an opinion from our
counsel, Goodwin, Procter & Hoar LLP, dated October 16, 1998. Their opinion
stated the following:

    --  that the Company has been and will be organized in conformity with the
       requirements for qualification as a REIT; and

    --  that the Company's proposed manner of operation will enable it to
       qualify as a REIT.

    This opinion was based on certain factual and other assumptions and
representations with respect to the Company's past and expected ongoing
businesses and investment activities and other customary matters. No assurances
can be given to you as to the accuracy of such assumptions or that the Company
has been able to comply with the representations it made to Goodwin, Procter &
Hoar LLP or will be able to comply with them in the future. Furthermore, this
opinion is not binding on the IRS or any court, and no assurance can be given
that we will operate in a manner so as to qualify or remain qualified as a REIT.
This opinion of Goodwin, Procter & Hoar LLP represented only their view, as of
the date of their opinion, based on their review and analysis of existing law,
which included no controlling precedent and which is subject to change (possibly
on a retroactive basis). The opinion has not been updated since it was issued in
October, 1998.

    Furthermore, both the validity of this opinion and the Company's continued
qualification as a REIT will depend on the Company's satisfaction of certain
asset, income, organizational, distribution and stockholder ownership
requirements on a continuing basis. Our operations have not been and will not be
monitored by Goodwin, Procter & Hoar LLP to ensure continued compliance with the
REIT requirements.

    If we were to fail to qualify as a REIT in any taxable year, we would be
subject to federal income tax (including any applicable alternative minimum tax)
on our taxable income at regular corporate rates, and

                                       20
<PAGE>
distributions to stockholders would not be deductible by the Company in
computing its taxable income. Any such corporate tax liability could be
substantial and would reduce the amount of cash available for distribution to
stockholders, which in turn could have an adverse impact on the value of (and
trading prices for) our Common Stock. Unless entitled to relief under certain
REIT provisions of the Code, we also would be disqualified from taxation as a
REIT for the four taxable years subsequent to the year during which we ceased to
qualify as a REIT.

    We must distribute annually at least 95% of our net taxable income
(excluding any net capital gain) in order to avoid corporate income taxation of
the earnings that we distribute. In addition, we will be subject to a 4%
nondeductible excise tax on the amount, if any, by which certain distributions
paid or deemed paid by the Company with respect to any calendar year are less
than the sum of:

    --  85% of the Company's ordinary income for that year;

    --  95% of the Company's capital gain net income for that year; and

    --  100% of the Company's undistributed taxable income from prior years.

    The amount of any net long-term capital gains that we elect to retain and
pay income tax on will be treated as distributed for purposes of the 4% excise
tax.

    We intend to make distributions to our stockholders to comply with the 95%
distribution requirement and to avoid the nondeductible excise tax. However,
differences in timing between the recognition of taxable income and the actual
receipt of cash could require the Company to borrow funds or sell assets on a
short-term basis to meet the 95% distribution requirement and to avoid the
nondeductible excise tax. The requirement to distribute a substantial portion of
the Company's net taxable income could cause the Company:

    --  to sell assets in adverse market conditions;

    --  to distribute amounts that represent a return of capital; or

    --  to distribute amounts that would otherwise be spent on future
       acquisitions, capital expenditures, or repayment of debt.

    Gains from the disposition of any asset held primarily for sale to customers
in the ordinary course of business generally will be subject to a 100% tax.

    It is anticipated that we may purchase mortgage loans. If we purchase such
assets and are deemed to have issued debt obligations having two or more
maturities (the payments on which correspond to payments on such mortgage loans)
such arrangement will be treated as a "taxable mortgage pool" for federal income
tax purposes. If all or a portion of the Company is considered a "taxable
mortgage pool," the Company's status as a REIT generally should not be impaired,
but a portion of the Company's taxable income may be characterized as "excess
inclusion income" and allocated to stockholders. Any excess inclusion income:

    --  could not be offset by net operating losses of a stockholder;

    --  would be subject to tax as "unrelated business taxable income" to a
       tax-exempt stockholder;

    --  would be subject to the application of federal income tax withholding
       (without reduction pursuant to any otherwise applicable income tax
       treaty), with respect to amounts allocable to foreign stockholders; and

    --  would be taxable (at the highest corporate tax rate) to the Company
       (rather than its stockholders) to the extent allocable to shares of stock
       of the Company held by disqualified organizations (generally, tax-exempt
       entities not subject to tax on unrelated business taxable income,
       including governmental organizations).

                                       21
<PAGE>
VOTING TRUST DISTRIBUTIONS

    In order to qualify as a REIT, we must satisfy certain requirements
regarding the sources of our gross income. In June 1999, we distributed to our
shareholders interests in a voting trust formed to hold shares of Wyndham, in
January 2000 we distributed to our shareholders interests in a voting trust
formed to hold shares of Cypress, and in March 2000, we distributed to our
shareholders interests in a voting trust formed to hold shares of CO Space. When
we distributed interests in the Wyndham, Cypress, and CO Space voting trusts, we
recognized gain with respect to each distribution equal to the excess, if any,
of the value of the shares distributed through the voting trust on the date of
distribution over our tax basis therein, and this gain constituted nonqualifying
income from non-real estate sources for purposes of the REIT gross income test.
Based on our valuations of the Wyndham shares, Cypress shares, and CO Space
shares on the dates of distribution and on current projections of Cypress' 2000
gross income, the gains recognized by us on the distributions should not violate
the REIT gross income test for 1999 or 2000. These valuations reflect our
judgment as to the value of the shares distributed on their respective
distribution dates, but the valuation of shares is a factual determination and
could be challenged by the IRS possibly causing us to fail our REIT income tests
for 1999 or 2000, as the case may be. Unless we were able to avail ourselves of
certain relief provisions, failure to meet the income tests would cause us to
lose our REIT status, in which case we would incur significant corporate taxes
and distributions to shareholders likely would be reduced. In addition, we
likely would not be able to reelect REIT status until the fifth year following
loss of REIT status.

ADVERSE IMPACT OF FUTURE LEGISLATION REGARDING REITS

    The Company's ability to qualify as a REIT, the benefits of REIT
qualification, and/ or our ability to use a BCP Sister Corp could be adversely
impacted by future legislation.

AGGREGATE STOCK OWNERSHIP LIMIT MAY RESTRICT BUSINESS COMBINATION OPPORTUNITIES

    To maintain our qualification as a REIT, five or fewer individuals may not
own (directly or indirectly) more than 50% of our Common Stock at any time
during the last half of our taxable year. As such, our Charter contains an
aggregate stock ownership provision which generally prohibits any single
stockholder from owning more than 9.8% of our Common Stock. In addition, our
Charter contains a look-through ownership limit that permits certain mutual
funds and certain other widely-held (other than pension plans as described in
Section 401(a) of the Code) to own up to 15% of our Common Stock. The Board of
Directors may waive or modify either of these two provisions if it is satisfied
(based upon the receipt of a ruling from the IRS or the advice of tax counsel)
that ownership in excess of this limit will not jeopardize our status as a REIT.
In addition, these ownership limits may inhibit or impede a change in control.
Such inhibitions and impediments could adversely affect stockholders' ability to
realize a premium over the then-prevailing market price for our Common Stock in
connection with such a transaction.

FOREIGN INVESTORS SHOULD CONSIDER TAX RISKS UNDER FIRPTA

    If the Company is not a domestically controlled REIT, non-U.S. Stockholders
who own and then sell our Common Stock will be taxed according to the Foreign
Investment in Real Property Tax Act of 1980 ("FIRPTA"). We will be a
domestically controlled REIT if non-U.S. persons own (directly or indirectly)
less than 50% of our Common Stock during specified testing periods. We cannot
assure you that we will continue to be a domestically-controlled REIT. Even if
not subject to FIRPTA, non-U.S. stockholders are subject to taxation under
certain other circumstances.

PLANS SHOULD CONSIDER ERISA RISKS OF INVESTING IN COMMON STOCK

    ERISA is a broad statutory framework that governs non-governmental employee
benefit plans in the United States. Fiduciaries of pension, profit-sharing or
other employee benefit plans subject to Title I of

                                       22
<PAGE>
ERISA ("ERISA Plans") should carefully consider the impact of ERISA and the
regulations of the Department of Labor (the "DOL") thereunder on the ERISA
Plan's decision to invest in our Common Stock. In particular, a fiduciary of an
ERISA Plan should consider whether its decisions with respect to these matters
would satisfy the requirements set forth in Part 4 of subtitle B of Title I of
ERISA, including:

    --  the diversification and prudence requirements of ERISA;

    --  the requirement that the decisions be in the best interests of the
       participants and beneficiaries of the ERISA Plan; and

    --  the requirement that the decisions be authorized under the appropriate
       governing instruments and investment policies of the ERISA Plan.

    ERISA also prohibits certain transactions involving an ERISA Plan and
persons who are "parties in interest" with respect to the ERISA Plan. In
addition, the Code provides for similar prohibited transaction rules applicable
to "plans" (as defined in Section 4975 of the Code) and "disqualified persons"
with respect to such plans. The fiduciary of an ERISA Plan or a plan described
in Section 4975 of the Code (referred to together herein as "Plans")
contemplating an investment in our Common Stock should consider whether the
acquisition of such Common Stock would result in a prohibited transaction under
ERISA and/or the Code, and (if so) whether an exemption from these prohibited
transaction rules is available. In addition, the Plan Assets Regulation provides
that (subject to certain exceptions) the assets of an entity in which a Plan
holds an equity interest may be treated as assets of the investing Plan, in
which event the underlying assets of such entity (and transactions involving
such assets) would be subject to ERISA and applicable provisions of the Code
(including prohibited transaction provisions of ERISA and the Code).

    We intend to take such steps as may be necessary to qualify the Company and
the Operating Partnership (and any BCP Sister Corp.) for one or more of the
exceptions available under such regulation and, thereby, prevent the assets of
the Company from being treated as assets of any investing Plan. Specifically, we
will use our reasonable best efforts to qualify as a "real estate operating
company" (within the meaning of the Plan Assets Regulation) at least until such
time as our Common Stock qualifies as a class of "publicly offered securities"
(as such term is defined in such regulation). In addition, with respect to any
BCP Sister Corp., we will take such steps as may be necessary to qualify such
BCP Sister Corp. as an operating company or a venture capital operating company
or for one of the other available exceptions under the Plan Assets Regulation
prior to distributions of its equity interests (although no assurances can be
made in this regard).

CHANGES IN MANAGEMENT MAY BE DETERRED

    We are subject to the Maryland General Corporation Law (the "MGCL") because
we are incorporated in Maryland. Certain provisions of the MGCL:

    --  impose restrictions and require procedures with respect to business
       combinations, including (but not limited to) transactions with holders of
       more than 10% of the voting power of our equity securities; and

    --  limit voting rights for holders of 20% or more of the voting power of
       our stock.

    These provisions could discourage a takeover or other transaction involving
a change in control. Our Charter exempts from the MGCL any business combination
with Alan M. Leventhal, Lionel P. Fortin or current or future affiliates,
associates or other persons acting in concert as a group with either of
Messrs. Leventhal or Fortin. In addition, the right of the Participation Plan to
receive an Incentive Return in the event of a change of control of the Company
(as defined in the Operating Partnership Agreement) may deter third parties from
entering into transactions with the Company.

                                       23
<PAGE>
BOARD OF DIRECTORS MAY CHANGE CERTAIN POLICIES WITHOUT STOCKHOLDER CONSENT

    Our policies will be determined by our Board of Directors. The Board of
Directors may amend or revise these policies, or approve transactions that
deviate from these policies without a vote of the stockholders. These changes in
policy may be positive or negative.

LOSS OF INVESTMENT COMPANY ACT EXEMPTION WOULD ADVERSELY AFFECT THE COMPANY

    We intend to avoid regulation as an investment company under the Investment
Company Act of 1940. The Investment Company Act exempts entities that (directly
or through majority-owned subsidiaries) are "primarily engaged in the business
of purchasing or otherwise acquiring mortgages and other liens on and interests
in real estate" (the "Qualifying Interests"). The commission currently
interprets the Investment Company Act to exempt companies that:

    --  maintain at least 55% of their Assets in Qualifying Interests, and

    --  maintain an additional 25% in Qualifying Interests or other real
       estate-related assets.

    As such, the assets we may acquire are limited by this exemption. In
addition, we could be required to either:

    --  change the manner in which we conduct our operations to avoid being
       required to register as an investment company; or

    --  register as an investment company.

    Either of these possibilities could have an adverse effect on the Company
and the market price for our Common Stock.

LIMITATION ON LIABILITY OF OFFICERS AND DIRECTORS OF THE COMPANY

    Our Charter limits the liability of a director or officer to the Company and
our stockholders for money damages, except for liability resulting from:

    --  actual receipt of an improper benefit or profit in money, property or
       services; or

    --  active and deliberate dishonesty established by a final judgment as
       being material to the cause of action.

OTHER RISKS

RISK THAT MARKET FOR COMMON STOCK WILL NOT DEVELOP

    Our Common Stock presently has no established trading market and there is no
assurance one will develop. Our Common Stock has been accepted for trading in
the PORTAL Market, a real-time electronic National Association of Securities
Dealers marketplace that facilitates trading in securities offered pursuant to
Rule 144A transactions. We cannot assure you that an active trading market for
our Common Stock will develop in the PORTAL Market or elsewhere. In addition,
access to the PORTAL Market (unlike other prominent stock exchanges or Nasdaq
markets) is restricted to certain parties and can only be used for the trading
of certain restricted securities. Accordingly, we cannot assure you as to:

    --  the likelihood that an active market for our Common Stock will develop;

    --  the liquidity of any such market;

    --  your ability to sell your Common Stock; or

    --  the prices that you may obtain for your Common Stock.

(1) Millennium Tower has not been included in these figures because it is a
    development project. The joint venture between the Company and HA L.L.C. is
    building a Class A office/retail and residential high-rise building in
    downtown Seattle, Washington.

(2) Mathilda Research Centre has not been included in these figures because it
    is a development project. The joint venture between the Company and Mathilda
    Partners LLC is building two Class A office/ R&D buildings in Sunnyvale,
    California.

(3) The Company holds a 50% interest in The Athenaeum Portfolio which includes
    11 buildings, a nine screen-1,200 seat Cinema and 1,530 structured parking
    spaces.

(4) Fort Point Place includes two additional buildings that are not included in
    these figures. The two buildings consist of approximately 190,000 square
    feet of vacant warehouse space. We plan to renovate the warehouse space for
    use as residential condominiums. See --"Item 3. Legal Proceedings".

(5) Technology Square includes 955 structured parking spaces. Buildings 545, 565
    and 575 have been renamed Buildings 200, 400, and 500, respectively. The
    rentable area of Buildings 200, 400 and 500 have been modified to reflect
    recent re-measurements according to BOMA standards. Buildings 400 and 500
    are currently undergoing substantial renovation and releasing programs.

ITEM 3. LEGAL PROCEEDINGS.

    Our Fort Point Place property, located in the South Boston Waterfront
District, is composed of four buildings. Two of the buildings consist of office
space and are leased to third parties. The other two buildings are vacant and
were formerly utilized as warehouse space. In July 1999, we successfully
obtained all necessary zoning approvals and other entitlements in order to be
able to convert the two warehouse buildings into residential condominiums with
some ground floor retail space. Just prior to the expiration of the appeal
period for the zoning approvals, The Gillette Company, which operates a
manufacturing facility in South Boston, filed an action against the City of
Boston and the Company in the Superior Court of the Commonwealth of
Massachusetts (Civil Action No. 99-4061-G) in which Gillette seeks to overturn
the zoning approvals obtained by us. Both we and the City of Boston are
vigorously defending the approvals granted by the City to our application for
zoning and ancillary entitlements for the condominiums. We obtained a building
permit for the condominiums during 1999 and are proceeding with construction
during the pendency of the litigation.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

    There were no matters submitted to a vote of Stockholders during the fourth

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS.

OVERVIEW

    This Form 10-K contains forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934. The words "believe", "expect", "anticipate", "intend",
"estimate" and other expressions which are predictions of or indicate future
events and trends and which do not relate to historical matters identify
forward-looking statements. Our actual results could differ materially from
those set forth in the forward-looking statements. Certain factors that might
cause such a difference include the following: real estate investment
considerations, such as the effect of economic and other conditions in the
market area on cash flows and values; the need to

                                       27
<PAGE>
renew leases or relet space upon the expiration of current leases, and the
ability of a property to generate revenue sufficient to meet debt service
payments and other operating expenses; risks associated with borrowing, such as
the possibility that we will not have sufficient funds available to make
principal payments on outstanding debt and outstanding debt may be refinanced at
higher interest rates or otherwise on terms less favorable to us; the impact of
pending or future litigation; variations in quarterly operating results;
securities held for investment are subject to fluctuations in valuation based
upon the performance of the underlying business; risks that some of our
investments could cause us to fail to qualify as a REIT, and those risks and
uncertainties contained elsewhere in this report and under the heading "Risk
Factors" on page 7 of our Registration Statement on Form S-11 as filed with the
Securities and Exchange Commission on June 16, 1998, as subsequently amended.

    The following discussion and analysis of the financial condition and results
of operations should be read in conjunction with the accompanying financial
statements and notes thereto. Our consolidated financial statements include
Beacon Capital Partners, Inc. ("BCP") and Beacon Capital Partners, L.P. (the
"Operating Partnership"), our majority-owned partnership.

RESULTS OF OPERATIONS

COMPARISON OF THE YEAR ENDED DECEMBER 31, 1999 AND THE PERIOD FROM JANUARY 21,
1998 (INCEPTION) TO DECEMBER 31, 1998.

    Changes in revenues and expenses from 1998 to 1999 are due primarily to our
property investment and acquisitions during those years. The Athenaeum Portfolio
investment was made in May, 1998; Technology Square and the Draper Building were
acquired in June, 1998; the Dallas Office and Industrial Portfolio was acquired
in July, 1998; and Fort Point Place was acquired in July, 1999. Rental income,
reimbursement revenues, equity earnings, property operating costs, real estate
taxes and depreciation and amortization are reflected in operating results only
from the date of acquisition, so year to year results do not reflect two full
years' results for any of these properties.

    Our total revenues increased $12.1 million to $38.6 million for the year
ended December 31, 1999 as compared to $26.5 million for the period from
January 21, 1998 (Inception) to December 31, 1998. The increase was due to
increased revenues from acquired properties of $13.2 million, increased equity
income from The Athenaeum Portfolio of $1.6 million and an increase in other
income of $1.4 million offset by a decrease in interest and dividend income of
$4.1 million. Revenues for The Athenaeum Portfolio were $30.5 million and
expenses were $20.9 million for the year ended December 31, 1999; we recognize
50% of its net earnings. The $4.1 million decrease in interest and dividend
income was primarily the result of a reduction in investment cash on hand due to
our use of proceeds from our March, 1998 Offering (the "Offering") to fund
property acquisitions and investments, offset by the interest earned on the
mortgage note receivable and dividends received in 1999.

    Our total expenses increased $17.3 million to $34.1 million for the year
ended December 31, 1999 as compared to $16.8 million for the period from
January 21, 1998 (Inception) to December 31, 1998. The increase was due to the
acquired properties operating expenses, real estate taxes and interest expense
of $2.9 million, $2.9 million and $1.8 million, respectively, general and
administrative expenses of $1.3 million, affiliate formation expenses of
$4.0 million and depreciation and amortization expense of $4.4 million. The
$4.0 million of affiliate formation expenses were costs incurred for the
formation of Beacon Capital Strategic Partners, L.P. ("BCSP") and consist of
underwriter commissions, legal and professional services not reimbursed by the
partners of BCSP. See --"Investing Activities".

    The extraordinary item, net of minority interest, was ($1.0) million for the
year ended December 31, 1999 as compared to zero for the period from
January 21, 1998 (Inception) to December 31, 1998. The expense was due to the
write-off of deferred financing fees and costs associated with the Bankers Trust
Company original $100 million note which was substantially modified. See
- - --"Financing Activities".

    The minority interest in consolidated partnership represents the portion of
the Operating Partnership that is not owned by the Company.

LIQUIDITY AND CAPITAL RESOURCES

    Cash and cash equivalents were $76.9 million at December 31, 1999 as
compared to $174.6 million at December 31, 1998. The decrease of $97.7 million
was primarily the result of (i) the purchase of Series B Convertible Preferred
Stock ("Series B Preferred") of Wyndham International, Inc. ("Wyndham"),
(ii) the acquisition of Fort Point Place, (iii) the payment of Technology Square
redevelopment costs, (iv) the payment of the January 1999 dividend to
stockholders and distribution to minority interests, and (v) investments in
Mathilda Research Centre, Millennium Tower, Cypress Communications Inc.
("Cypress"), and CO Space Inc. ("CO Space"), all offset by (i) proceeds received
from the Bankers Trust Company interim financing note payable (the "Interim
Financing"), (ii) the proceeds received from the Fort Point Place loan, and
(iii) cash flow from operations.

    Cash and cash equivalents were $174.6 million at December 31, 1998, which
was primarily the result of (i) private offering proceeds, (ii) cash flow from
operations, (iii) the issuance of Operating Partnership units, and (iv) a
distribution received from The Athenaeum Portfolio offset by (i) the cost of
acquiring Technology Square, The Draper Building and the Dallas Office and
Industrial Portfolio and (ii) investments in The Athenaeum Portfolio, Mathilda
Research Centre, Millennium Tower and Cypress.

SHORT AND LONG-TERM LIQUIDITY

    We have considered our short-term (up to 12 months) liquidity needs and the
adequacy of expected liquidity sources to meet these needs. We believe that our
principal short-term operating liquidity needs are to fund normal recurring
expenses, debt service requirements and the minimum distribution required to
maintain the Company's REIT qualification under the Internal Revenue Code of
1986, as amended. We believe that these needs will be provided by cash flow from
operating activities and current cash balances. We believe our 2000 distribution
requirement to maintain our REIT qualification will be met from our January 5,
2000 dividend of preferred shares of Cypress subject to a voting trust, our
March 9, 2000 cash dividend of $0.50 per share, and our March 24, 2000 dividend
of preferred shares of CO Space subject to a voting trust. See --"Investing
Activities". We believe our other short-term liquidity needs are the funding of
current real estate investments, developments, redevelopments, BCSP capital
commitments, securities held for investment, the share repurchase program and
the repayment of the Interim Financing (in the event that the loan is not
extended). We expect to fund these needs from current cash balances, mortgages
and other debt instruments, and through sales of certain assets.

    We expect to meet long-term (greater than 12 months) liquidity requirements
for the costs of additional development, real estate and real estate related
investments, scheduled debt maturities, major renovations, expansions and other
non-recurring capital improvements through secured and unsecured indebtedness,
joint ventures, sales of certain assets, and from current cash balances.

FINANCING ACTIVITIES

    On March 20, 1998, we completed an initial private offering (the "Offering")
issuing 17,360,769 shares of Common Stock with proceeds, net of offering costs,
of $323.1 million. On April 3, 1998 and April 13, 1998, through the exercise of
the underwriter's over-allotment option, 3,613,163 additional shares were issued
with proceeds, net of offering costs, of $66.6 million.

    In connection with our reincorporation (through a merger) as a Maryland
corporation, we established Beacon Capital Partners, L.P., the Operating
Partnership. As contemplated in the Offering, an entity controlled by
Messrs. Leventhal and Fortin was to contribute $4.2 million to the Operating
Partnership for a 1% limited partnership interest. In order to comply with the
requirements of ERISA, such contribution could only be made subsequent to the
closing of our first real estate transaction. The $4.2 million contribution was
made on May 4, 1998.

    On June 9, 1999, Millennium Tower, L.L.C., the joint venture formed to
develop Millennium Tower, obtained a three-year $45 million construction loan
from two institutions. The loan may be extended for one year if certain
conditions are met. The loan initially bears interest at a rate of LIBOR plus
250 basis points and may decrease to a rate of LIBOR plus 200 basis points when
the project achieves certain pre-

                                       29
<PAGE>
leasing and debt service coverage thresholds. The loan is secured by a mortgage
and an assignment of rents. Each of the principals in the venture has provided a
completion guarantee and a repayment guarantee (in the aggregate amount of $12
million) equal to their pro-rata interest in the venture. As of December 31,
1999, none of the loan commitment has been disbursed.

    On June 28, 1999, we obtained $100 million of secured Interim Financing from
Bankers Trust Company. On December 3, 1999, we executed an amendment to the
Interim Financing that increased the loan amount to $130 million. The Interim
Financing matures in June 2000, and subject to certain conditions may be
extended for one year. Outstanding balances under the Interim Financing bear
interest at a rate spread over the base rate or Eurodollar rate, as applicable.
The spread is based upon certain loan to value ratios. At December 31, 1999, the
outstanding balance of the Interim Financing was $122.5 million and the interest
rate was 9.0%. The Interim Financing requires monthly payments of interest only
and is secured by mortgages and assignments of rents on the following
properties: 200, 400 and 500 Technology Square, The Draper Building, Bank One
LBJ, Brandywine Place, Crosspoint Atrium, Forest Abrams Place, Richarson
Commerce Centre, Sherman Tech, and Venture Drive Tech Center. Our ability to
borrow under the Interim Financing is subject to our ongoing compliance with a
number of financial and other covenants. In connection with the Interim
Financing amendment that increased the loan amount to $130 million, we recorded
an extraordinary item of ($1.0) million, net of minority interest, for the
write-off of fees and costs to establish the original $100 million loan.

    On October 6, 1999, we obtained a 30 month $16 million loan from an
institutional lender secured by Fort Point Place. The loan may be extended for
one year if certain conditions are met. As of December 31, 1999, the lender has
disbursed $12.5 million of the loan and the balance will be available when the
project achieves certain leasing and debt service coverage thresholds. The loan
bears interest at a rate of LIBOR plus 200 basis points and requires monthly
payments of interest only. As of December 31, 1999, the interest rate was 8.17%.

    On October 29, 1999, Mathilda Associates LLC, the joint venture formed to
develop Mathilda Research Centre, obtained a three-year $44 million construction
loan from an institutional lender. As the construction of the two buildings at
Mathilda Research Centre will be phased, the lender's obligation to make
disbursements for the second building ($17 million) is subject to the project's
satisfaction of certain conditions. The loan initially bears interest at a rate
of LIBOR plus 275 basis points and may decrease to a rate of LIBOR plus 250
basis points when the first building is complete and Juniper Networks, Inc.
("Juniper Networks") takes occupancy. The Operating Partnership has provided a
completion guarantee. As of December 31, 1999, approximately $5.6 million of the
loan has been disbursed and the interest rate was 8.75%.

    On March 17, 2000, BCSP obtained a $137.5 million secured revolving credit
facility (the "Credit Facility"). The Credit Facility matures on June 30, 2001
and bears interest at a rate of LIBOR plus 87.5 basis points. BCSP's ability to
borrow under the Credit Facility is subject to its ongoing compliance with a
number of financial and other covenants. The Credit Facility is fully recourse
to BCSP and is secured by, among other things, a pledge and assignment of all
uncalled capital commitments of the partners. As of March 17, 2000 the
outstanding balance of the Credit Facility was $42 million.

INVESTING ACTIVITIES

    On May 1, 1998, we acquired The Athenaeum Portfolio, an eleven building,
970,000 square foot mixed-use portfolio located in Cambridge, Massachusetts. The
aggregate consideration for the properties was $195 million, consisting of
approximately $125.9 million in cash and the assumption of approximately
$69.1 million of first mortgage debt. We used proceeds from the Offering for the
cash portion of the acquisition. Subsequent to the closing of the transaction,
we completed the formation of a joint venture with PW Acquisitions IX, LLC, an
affiliate of PaineWebber, in which both parties hold a 50% interest in the
master limited liability company that controls the two limited liability
companies holding title to the properties.

                                       30
<PAGE>
    On June 24, 1998, we acquired a four-building complex known as Technology
Square and an adjacent building known as The Draper Building. The properties are
located in Cambridge, Massachusetts and consisted of approximately 1,026,000
square feet. The aggregate consideration for the properties was $123 million,
consisting of approximately $71.6 million in cash and the issuance of
approximately $51.4 million of units of limited partnership interest in the
Operating Partnership. We used proceeds from the Offering for the cash portion
of the acquisition. In 1999, we began renovation and releasing of two of the
buildings and razed one building. We commenced a new development plan to
construct approximately 600,000 square feet of additional office and laboratory
space. Construction of the first building (176,000 square feet) has begun and we
currently expect it to be completed in the second quarter of 2001.

    On July 1, 1998, we acquired the Dallas Office and Industrial Portfolio, a
1,335,000 square foot portfolio of seven office properties and seven research &
development properties located in suburban Dallas, Texas. The aggregate
consideration for the properties was $91.2 million, consisting of approximately
$69.5 million in cash and the assumption of approximately $21.7 million of first
mortgage debt. Seven of the properties are collateral for various first mortgage
debt and the other seven properties are collateral for the Interim Financing.
See --"Capitalization". We used proceeds from the Offering for the cash portion
of the acquisition.

    On August 9, 1998, we entered into a joint venture agreement with Mathilda
Partners LLC, an affiliate of Menlo Equities (a California based developer). The
joint venture is developing Mathilda Research Centre, two four-story Class A
office/R&D buildings with surface parking in Sunnyvale, California. We agreed to
fund up to $19.8 million of the development. In conjunction with the
construction loan closing, our equity investment was reduced to $17.5 million.
See --"Financing Activities". As of December 31, 1999, we had funded our entire
commitment using proceeds from the Offering and Interim Financing. The estimated
cost of the development is approximately $64 million. On June 18, 1999, the
joint venture executed a lease with Juniper Networks, for one of the two
buildings comprising approximately 144,000 of the development's approximately
267,000 square feet and on February 28, 2000, Juniper Networks executed its
option to lease the second building. We expect to complete the first building in
June 2000 and the second building in June 2001.

    On September 1, 1998 we entered into a joint venture agreement with HA
L.L.C., an affiliate of Martin Smith Real Estate Services (a Seattle based real
estate company). The joint venture is developing Millennium Tower, a 19-story,
approximately 261,000 square foot, office/retail and residential tower, in
downtown Seattle, Washington. HA L.L.C. contributed the land at an agreed value
of $10.5 million and we agreed to fund $19 million of the development, of which,
as of December 31, 1999, we had funded approximately $13.3 million using
proceeds from the Offering and Interim Financing. The joint venture has obtained
a $45 million construction loan from two institutional lenders to finance the
balance of the development costs. See --"Financing Activities". The estimated
cost of the development is approximately $72 million, including the value of the
land. We expect to complete the project in the fourth quarter of 2000. Our
residential portion of the investment is held by BCP Millennium
Residential, Inc., a Massachusetts corporation ("BCP Millennium Residential").
The voting common stock of BCP Millennium Residential is controlled by
Messrs. Leventhal and Fortin. The Operating Partnership owns approximately 99%
of the economic interest in BCP Millennium Residential.

    On September 30, 1998 and October 8, 1999, we invested an aggregate of
$11 million to acquire preferred stock in Cypress, a company that provides
bundled communications services to tenants in multi-tenant commercial buildings.
As of December 31, 1999, our $11 million investment represented a 9.5% fully
diluted ownership position. We used proceeds from the Offering and Interim
Financing for the investment. As of December 31, 1999, the preferred stock
investment was held by both the Operating Partnership and Tenant
Communications, Inc., a Massachusetts corporation. On January 5, 2000, we
distributed all of the preferred stock of Cypress valued at approximately $0.75
per share and unit to a voting trust, (the trustee of which is a subsidiary of
the Operating Partnership) and then distributed our interest in the voting trust
to our stockholders and unitholders. On February 10, 2000, Cypress successfully

                                       31
<PAGE>
completed its initial public offering. Cypress trades on the NASDAQ National
Market under the symbol CYCO. At the IPO, each share of preferred stock split
into 4.5 shares of common stock.

    On June 30, 1999, we acquired 215 Fremont Street, a 299,000 square foot
building located in the South Financial District of San Francisco, California.
The purchase price was $33.5 million. We used proceeds from the Interim
Financing for the investment. We intend to expand and fully redevelop the
property into Class A office space. On October 25, 1999, this investment was
transferred to one of our affiliates, BCSP, and we were reimbursed for all costs
incurred to date associated with the acquisition, redevelopment and carrying of
the property.

    On June 30, 1999, we purchased 1,050,000 shares of Series B Preferred at a
net price of approximately $102.9 million. Simultaneous with this transaction,
we transferred all of these shares of Series B Preferred to a voting trust (the
"Wyndham Voting Trust") (the trustee of which is a subsidiary of the Operating
Partnership) and declared and paid a dividend of approximately $4.34 per share
of common stock of BCP and a distribution of approximately $4.34 per operating
partnership unit of the Operating Partnership. The aggregate value of the
dividend and distribution was approximately $103.1 million and primarily
consisted of our interest in shares of the Series B Preferred subject to the
Wyndham Voting Trust. Stockholders not able to receive such interests received
cash of equivalent value. We used proceeds from the Offering for the Series B
Preferred purchase. Subsequent to June 30, 1999, we purchased approximately
57,578 Wyndham Voting Trust interests at an aggregate price of approximately
$5.3 million. We used proceeds from the Interim Financing for the purchase of
the Wyndham Voting Trust interests.

    On July 1, 1999, we purchased 450,000 shares of Series B Preferred at a net
price of approximately $44.1 million. We used proceeds from the Offering for the
Series B Preferred purchase. On October 29, 1999, we transferred 244,340 of
these shares of Series B Preferred to Beacon Lodging, Inc., a Massachusetts
corporation ("Beacon Lodging"). The voting common stock of Beacon Lodging is
controlled by Messrs. Leventhal and Fortin. We own approximately 99% of the
economic interests in Beacon Lodging. On December 9, 1999, Wyndham completed a
rights offering to its current common shareholders and redeemed approximately
8,399 shares of our Series B Preferred at a price of approximately
$0.9 million.

    Wyndham's annual dividend on the Series B Preferred is 9.75% paid quarterly,
partially in cash and partially in paid-in-kind shares.

    On July 13, 1999, we purchased Fort Point Place, a four-building, 335,000
square foot office and warehouse property located in the Boston, Massachusetts
South Boston Waterfront District for aggregate consideration of approximately
$24.3 million. Two buildings consist of approximately 145,000 square feet of
office space. The other two buildings consist of approximately 190,000 square
feet of warehouse space which were delivered to us vacant. We intend to renovate
the warehouse space for use as residential condominiums. See --"Item 3. Legal
Proceedings". We used proceeds from the Interim Financing for the acquisition.

    On October 1, 1999, we completed the initial closing for BCSP, a real estate
limited partnership, of which BCP Strategic Partners LLC, our wholly-owned
subsidiary, is the General Partner. Subsequent to October 1, 1999, we completed
additional closings and as of March 28, 2000, (the BCSP final closing date),
equity commitments totaled $287.5 million, of which our equity commitment was
$57.5 million. The commitments include investments from various endowments,
foundations, pension funds and other institutional investors. The fund will
invest in U.S. domestic real estate with a primary focus on office properties.
The strategy will include redevelopment, development and other real estate
opportunities where we can maximize value through our operating skills and
expertise. BCSP will be our exclusive real estate investment vehicle for a
period of up to two years. As of December 31, 1999, none of our committed
investment has been funded. In connection with the formation of BCSP, for the
year ended December 31, 1999, we incurred affiliate formation expenses of
approximately $4.0 million. The expenses consist of underwriter commissions,
legal and professional services not reimbursed by the partners of BCSP.

    The Draper Building is 100% leased to The Charles Stark Draper Laboratory,
Inc. ("Draper") on a long-term lease which expires on October 19, 2001. The
lease contained extension options through October 19, 2051. The lease states
that the first extension option was "to be exercisable by notice from

                                       32
<PAGE>
Tenant to Landlord given not later than the end of the 23rd year of the Term
[October 19, 1999]." All subsequent extension options were only exercisable if
Draper had exercised its first extension option. The Company did not receive a
notice from Draper stating that it was exercising its extension option under the
lease. The lease also contains an option to acquire The Draper Building and a
right of first offer to acquire The Draper Building, each under certain
circumstances.

    The extension options in the lease provided for fixed rental rates which
were substantially below the current market rate. Prior to the occurrence of the
event described above, the Company had valued The Draper Building under the
assumption that Draper would exercise its extension options. The Company does
not believe that this assumption is still warranted.

    On November 12, 1999, we invested $8 million to acquire preferred stock in
CO Space, a company that provides co-location space for data storage,
telecommunication carriers, and web-hosting applications. We used proceeds from
the Interim Financing for the investment. Dividends will be earned on our
investment as and when dividends are declared on the preferred stock or any
class of stock in CO Space. The preferred stock will be treated preferentially
upon a liquidation of CO Space, should a liquidation event occur. As of
December 31, 1999, this investment represented a 19% ownership position on a
fully diluted basis and was held by the Operating Partnership. On January 28,
2000, the Operating Partnership transferred 10% of its shares of CO Space
(representing 100% of its voting interest) to Shared Communications
Spaces, Inc., a Massachusetts corporation ("Shared Communications"). The voting
common stock of Shared Communications is controlled by Messrs. Leventhal and
Fortin. The Operating Partnership owns approximately 99% of the economic
interests in Shared Communications. On March 24, 2000, we distributed all of the
preferred stock of CO Space valued at approximately $0.34 per share and unit to
a voting trust (the trustee of which is a subsidiary of the Operating
Partnership), and then distributed our interest in the voting trust to our
stockholders and unitholders.

CAPITALIZATION

    As of December 31, 1999, our total consolidated debt was approximately
$153.7 million and our total consolidated debt plus our proportionate share of
total unconsolidated debt was approximately $202.7 million. The following table
sets forth certain information regarding our consolidated and unconsolidated
debt obligations, including obligations relating to specific properties. All of
the debt is nonrecourse to us, with certain exceptions such as liability for
fraud, misapplication of insurance proceeds, environmental matters and certain
guarantees for completion of construction and repayment of interest.

FUNDS FROM OPERATIONS

    We believe that to facilitate a clear understanding of our operating
results, Funds from Operations ("FFO") should be examined in conjunction with
net income. The definition of FFO was clarified in the National Association of
Real Estate Investment Trusts, Inc. ("NAREIT") White Paper, adopted by the
NAREIT Board of Governors in March 1995, and subsequently clarified in October,
1999, as net income (loss) (computed in accordance with generally accepted
accounting principles), excluding gains (losses) from sales of properties, plus
real estate related depreciation and amortization, and after adjustments for
unconsolidated partnerships and joint ventures. Adjustments for unconsolidated
partnerships and joint ventures will be calculated to reflect FFO on the same
basis. FFO should not be considered as a substitute for net income, as an
indication of our performance, as a substitute for cash flow or as a measure of
our liquidity. The following table presents the calculations of FFO based upon
the October, 1999 definition.

(1) Total area in square feet covered by such leases.

(2) Percentage of total square feet of our portfolio.

(3) Annualized expiring base rental income represented by such leases in the
    year of expiration plus the current tenant payments on account of operating
    expense and real estate tax escalation charges.

(4) Calculated as annual rent divided by the total annual rent.

(5) The number of tenants whose leases will expire.

ENVIRONMENTAL MATTERS

    We believe, based upon internal reviews, environmental site assessments
performed by consultants, existing plans to mitigate and monitor the sites and
financial commitments of certain prior owners and tenants, that the future costs
relating to environmental remediation and compliance will not have a material
adverse effect on our financial condition, results of operations, or liquidity.

INFLATION

    Most of our leases require tenants to pay increases in operating expenses,
including common area charges and real estate taxes, thereby reducing our risk
of the adverse effects of inflation. Leases also generally vary in term from
three years to ten years, further reducing our risk of the adverse effects of
inflation.

YEAR 2000 READINESS DISCLOSURE

    The Year 2000 compliance issue concerns the inability of computer systems to
accurately calculate, store or use a date after 1999. The inability of a
computer to properly process dates after 1999 could result in system failures or
miscalculations. Such failures in our computers could lead to disruptions in our
activities and operations. If we fail, or our significant tenants or vendors
fail, to make necessary modifications and conversions on a timely basis to
remedy these problems, the Year 2000 issue could have a material adverse effect
on the Company and its results of operations or financial position. We believe
that our competitors face similar risks in regard to Year 2000.

    We designed and implemented a plan to address Year 2000 issues. We have not
experienced any Year 2000 related issues and we did not incur any material costs
to address Year 2000 compliance.

    The inability of the Company, or our tenants or vendors, to continue to be
Year 2000 compliant could lead to declining occupancy rates, higher operating
expenses and other adverse effects which are not quantifiable at this time. The
failure of any of these parties to continue to be Year 2000 compliant could have
a material adverse effect on our results of operations or financial position.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

    We are exposed to certain financial market risks, the most predominant being
fluctuations in interest rates. Interest rate fluctuations are monitored by
management as an integral part of our overall risk management program, which
recognizes the unpredictability of financial markets and seeks to reduce the
potentially adverse effect on our results of operations. The effect of interest
rate fluctuations historically has been small relative to other factors
affecting operating results, such as rental rates and occupancy.

    The following table summarizes our debt obligations outstanding as of
December 31, 1999. This information should be read in conjunction with Notes 5
and 6 to the consolidated financial statements.

                         REPORT OF INDEPENDENT AUDITORS

To the Board of Directors and Stockholders of
Beacon Capital Partners, Inc.

    We have audited the accompanying consolidated balance sheets of Beacon
Capital Partners, Inc. as of December 31, 1999 and 1998, and the related
consolidated statements of operations, stockholders' equity, and cash flows for
the year ended December 31, 1999 and for the period from January 21, 1998
(inception) to December 31, 1998. Our audit also included the financial
statement schedule listed in the Index at Item 14(a). These financial statements
and schedule are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements and
schedule based on our audits.

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

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Beacon Capital
Partners, Inc. at December 31, 1999 and 1998, and the consolidated results of
its operations and its cash flows for the year ended December 31, 1999 and for
the period from January 21, 1998 (inception) to December 31, 1998, in conformity
with accounting principles generally accepted in the United States. Also, in our
opinion, the related financial statement schedule, when considered in relation
to the basic financial statements taken as a whole, presents fairly in all
material respects the information set forth therein.

1. ORGANIZATION

    Beacon Capital Partners, Inc. ("BCP") was incorporated on January 21, 1998
as a Massachusetts corporation (the "Formation") and was initially capitalized
through loans from the two founders of BCP, Messrs. Leventhal and Fortin. The
loans were repaid in May 1998. BCP qualifies as a real estate investment trust
under the Internal Revenue Code of 1986, as amended. BCP was established to
conduct real estate investment and development activities and currently operates
in one segment.

    On March 17, 1998, BCP was reincorporated as a Maryland corporation and on
March 20, 1998 it completed an initial private offering (the "Offering") in
accordance with Section 4(2) of the Securities Act. BCP initially issued
17,360,769 common shares with proceeds, net of expenses, of $323,110. In April,
1998, 3,613,163 additional shares were issued through the exercise of the
underwriter's over-allotment, with proceeds, net of expenses, of $66,620.

    In connection with the reincorporation of BCP in Maryland, BCP established
Beacon Capital Partners, L.P. (the "Operating Partnership"). BCP and the
Operating Partnership are collectively referred to as the "Company". The
Operating Partnership is a Delaware limited partnership. BCP is the sole general
partner of, and, as of December 31, 1999, holds approximately 88% of the
economic interest in the Operating Partnership. BCP holds an approximate 1%
general partnership interest in the Operating Partnership and the balance is
held as a limited partnership interest. The limited partnership interests not
held by BCP are presented as minority interest in the accompanying consolidated
financial statements. The term of the Operating Partnership commenced on
March 16, 1998 and shall continue until January 1, 2056 or until such time as a
Liquidating Event, as defined, has occurred.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF ACCOUNTING

    The accompanying consolidated financial statements are prepared in
accordance with generally accepted accounting principles and include the
accounts of BCP and its majority-owned subsidiary, Beacon Capital
Partners, L.P. BCP consolidates all wholly-owned subsidiaries and those
majority-owned subsidiaries in which it exercises control. BCP uses the equity
method of accounting for its investments and earnings in joint ventures and
corporations in which BCP shares influence over, but does not control, operating
and financial policy. BCP uses the cost method of accounting to account for its
investments and earnings in entities in which BCP does not influence operating
and financial policy. Losses in excess of investments are not recorded where BCP
is under no legal obligation and has neither guaranteed nor intends to provide
any future financial support to the respective investment. All significant
intercompany transactions and balances have been eliminated in consolidation.

    Minority interest in consolidated partnership represents Operating
Partnership units not held by BCP. As of December 31, 1999, $51,359 in units
were issued in connection with the purchase of the property known as Technology
Square and The Draper Building, and $4,228 in units were issued to
Messrs. Leventhal's and Fortin's family trusts for cash.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
USE OF ESTIMATES

    The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amount of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements. Actual results could differ from those estimates.

REAL ESTATE

    Buildings are recorded at cost and are depreciated on the straight-line
method over their estimated useful life of forty years. The cost of buildings
includes the purchase price of the property, capitalized interest, legal fees,
and other acquisition and development costs. Acquisition and development costs
generally consist of third party costs and internal direct costs. Internal costs
relating to the acquisition of operating properties are expensed as incurred.

    BCP measures impairment in accordance with FASB Statement No. 121,
ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE
DISPOSED OF, which requires impairment losses to be recorded on specific
long-lived assets used in operations where indicators of impairment are present
and the undiscounted cash flows estimated to be generated by those assets are
less than the assets' carrying amount.

    Furniture, fixtures and equipment are depreciated using the straight-line
method over their expected useful lives of three to ten years.

DEFERRED FINANCING AND LEASING COSTS

    Deferred financing costs are fees and costs incurred to obtain long-term
financing and are being amortized over the terms of the respective loans.
Deferred leasing costs are fees and costs incurred in the successful negotiation
of leases, including brokerage, legal and other costs, and are being amortized
on a straight-line basis over the terms of the respective leases.

CASH AND CASH EQUIVALENTS

    Cash and cash equivalents consist of short-term, highly liquid assets with
original maturities of three months or less from the date of purchase.

RESTRICTED CASH

    Restricted cash consists of cash held in escrow as required by lenders to
satisfy real estate taxes.

FAIR VALUE OF FINANCIAL INSTRUMENTS

    BCP is required to disclose the fair values of financial instruments for
which it is practicable to estimate such fair value. The fair values of
financial instruments are estimates based upon market conditions and perceived
risks at December 31, 1999 and require varying degrees of management

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
judgment. The fair values of financial instruments presented may not be
indicative of amounts BCP could realize on the disposition of the financial
instruments.

    Cash, cash equivalents and restricted cash are carried at an amount, which
due to their nature, approximates fair value.

    BCP computes the fair value of its mortgage notes payable based upon the
discounted cash flows of the collateralized properties at a discount rate that
approximates BCP's effective borrowing rate. BCP has determined that the fair
value of its mortgage notes approximates their carrying value.

REVENUE RECOGNITION

    Revenues are recognized when earned and the amounts can be reasonably
estimated on the accrual basis of accounting. Rental income from operating
leases is recognized on a straight-line basis over the life of the lease
agreements.

INCOME TAXES

    BCP is taxed as a real estate investment trust ("REIT") under the Internal
Revenue Code. As a REIT, BCP will generally not be subject to Federal income
taxes to the extent that it makes timely distributions to its shareholders at
least equal to its taxable income and meets certain other requirements for
qualification as a real estate investment trust.

    BCP from time to time acquires and operates businesses that do not satisfy
the REIT qualification tests prescribed by the Internal Revenue Code.
Transactions that give rise to such assets and income are owned through taxable
corporate subsidiaries in which BCP holds the majority of economic interest but
less than 10% of the voting power. Such subsidiaries are subject to Federal,
state and local taxation.

STOCK OPTIONS AND OTHER AWARDS

    BCP has elected to follow Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" (APB 25) and related Interpretations
in accounting for its employee stock options because the alternative fair value
accounting provided for under FASB Statement No. 123, "Accounting for
Stock-Based Compensation," requires use of option valuation models that were not
developed for use in valuing employee stock options. Under APB 25, because the
exercise price of BCP's employee stock options equals the market price of the
underlying stock on the date of grant, no compensation expense is recognized.

    Compensation attributable to the Company's Long-Term Incentive Plan is
accrued as earned and will be charged to expense over the period covered by the
Long-Term Incentive Plan.

EARNINGS PER COMMON SHARE

    The computation of earnings per common share is based upon the weighted
average number of shares of common stock outstanding during the periods
subsequent to the Offering. As BCP has no dilutive securities, there is no
difference between basic and diluted earnings per share of common stock.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
NEW ACCOUNTING PRONOUNCEMENTS

    The Financial Accounting Standards Board has issued Statement of Financial
Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities" ("FAS 133"). FAS 133 is effective for years beginning after
June 15, 2000. BCP does not believe that the adoption of FAS 133 will have a
material impact on BCP's financial position or results of operations.

3. INVESTMENTS IN JOINT VENTURES AND CORPORATIONS

    The investments in joint ventures and corporations represents the Company's
interest in (i) a joint venture known as Beacon/PW Kendall LLC ("The Athenaeum
Portfolio"), (ii) a joint venture with Mathilda Partners LLC ("Mathilda Research
Centre"), (iii) a joint venture with HA L.L.C. ("Millennium Tower"),
(iv) investments in preferred stock of Cypress Communications, Inc. ("Cypress"),
(v) investments in Series B Convertible Preferred Stock ("Series B Preferred")

6. NOTE PAYABLE--INTERIM FINANCING

    On June 28, 1999, the Company obtained $100,000 of secured interim financing
(the "Interim Financing") from Bankers Trust Company. On December 3, 1999, the
Company executed an amendment to the Interim Financing that increased the loan
amount to $130,000. The Interim Financing matures in June 2000, and subject to
certain conditions may be extended for one year. Outstanding balances under the
Interim Financing bear interest at a rate spread over the base rate or
Eurodollar rate, as applicable. The spread is based upon certain loan to value
ratios. At December 31, 1999, the outstanding balance of the Interim Financing
was $122,500 and the interest rate was 9.0%. The Interim Financing requires
monthly payments of interest only and is secured by mortgages and assignments of
rents on certain properties. The net book value of the collateralized assets is
$156,324 at December 31, 1999. The Company's ability to borrow under the Interim
Financing is subject to the Company's ongoing compliance with a number of
financial and other covenants.

    In connection with the Interim Financing amendment that increased the loan
amount to $130,000, the Company recorded an extraordinary item of $1,047, net of
minority interest, for the write-off of fees and costs to establish the original
$100,000 loan.

7. STOCK INCENTIVE PLAN

    At inception, the Company adopted a Stock Incentive Plan, which authorizes
the grant of options to purchase shares of common stock and other stock-based
awards to the Company's executive officers, independent directors, employees and
other key persons. The Stock Incentive Plan is administered by the Compensation
Committee of the Board of Directors (the "Administrator").

    The maximum number of shares of common stock reserved and available for
issuance under the Stock Incentive Plan is such aggregate number of shares as
does not exceed the sum of (i) 12% of the outstanding equity interests in the
Company (including common stock and units subject to redemption rights) as
determined as of the final original offering closing date plus (ii) as of the
last business day of each calendar quarter ending after the final original
offering closing date, an additional positive number equal to 10% of any net
increase of outstanding equity interests in the Company. As of December 31,
1999, 2,796,726 shares of common stock have been reserved.

              (DOLLARS IN THOUSANDS, EXCEPT FOR PER SHARE AMOUNTS)

7. STOCK INCENTIVE PLAN (CONTINUED)
    The Stock Incentive Plan permits the granting of (i) options to purchase
common stock intended to qualify as incentive stock options ("Incentive
Options") under Section 422 of the Internal Revenue Code and (ii) options that
do not so qualify ("Non-Qualified Options"). The option exercise price of each
option may not be less than 100% of the fair market value of the common stock on
the date of grant in the case of Incentive Options, and may not be less than 25%
of the fair market value of the common stock on the date of grant in the case of
Non-Qualified Options. The term of each option will be fixed and may not exceed
ten years from date of grant in the case of an Incentive Option. The
Administrator will determine at what time or times each option may be exercised
and, subject to the provisions of the Stock Incentive Plan, the period of time,
if any, after retirement, death, disability or termination of employment during
which options may be exercised. Options may be made exercisable in installments,
and the exercise of options may be accelerated by the Administrator.

    Changes in options outstanding under the Stock Incentive Plan during the
period were as follows:

</TABLE>

    Options granted in 1999 were to directors of the Company, at less than the
current market value of the stock. Any difference between market value and the
strike price of the option has been recognized in the current period as
compensation expense.

    The Company has adopted SFAS No. 123, "Accounting for Stock-Based
Compensation". SFAS No. 123 requires the recognition of, or disclosure of,
compensation expense for grants of stock options or other equity instruments
issued to employees based on the fair value at the date of grant.

    As required under SFAS No. 123, the following pro forma net income and net
income per share presentations reflect the amortization of the option grant fair
value as expense. For purposes of this disclosure, the estimated fair value of
the options is amortized to expense over the options' vesting periods.

The following is the Company's pro forma information for the year ended

</TABLE>

    Significant assumptions used in determining this value include a risk free
interest rate of six percent, expected life of the options of five years, and a
dividend rate of 10%.

    The effects on pro forma disclosures of applying SFAS No. 123 are not likely
to be representative of the effects on pro forma disclosures in future years as
the period presented includes only two years of option grants under the Stock
Incentive Plan.

8. LONG-TERM INCENTIVE PLAN

    At inception, the Company adopted a Long-Term Incentive Plan which is
designed to reward certain members of management for growth of the Company's
Funds from Operations, as defined by the National Association of Real Estate
Investment Trusts, in excess of a specified benchmark. If the Company's Funds
from Operations exceeds the specified benchmark, management will be entitled to
receive an incentive return which shall be calculated on December 31, 2001 (the
"Determination Date").

    The incentive return shall equal the product of (A) 12% of the dollar amount
by which (i) the Actual Return, as defined, exceeds (ii) the Base Return, as
defined, multiplied by (B) the weighted average of shares of common stock and
units outstanding for the 12 months immediately preceding the Determination Date
multiplied by (C) the Company's Multiple, as defined.

    The Long-Term Incentive Plan has taken the form of a convertible unit which
was issued on March 16, 1998 to an affiliated organization in connection with
the closing of the Offering. The convertible unit is convertible at the
Determination Date into a certain number of incentive units in the Operating
Partnership with a fair market value equal to the amount of the incentive
return. No amount has been earned with respect to the Long-Term Incentive Plan.

                         REPORT OF INDEPENDENT AUDITORS

To the Members of Beacon/PW Kendall LLC

    We have audited the accompanying consolidated balance sheets of Beacon/PW
Kendall LLC as of December 31, 1999 and 1998 and the related consolidated
statements of operations, members' equity and cash flows for the year ended
December 31, 1999 and for the period from April 16, 1998 (inception) to
December 31, 1998. Our audit also included the financial statement schedule
listed in the Index at Item 14(a). These financial statements and schedule are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements and schedule based on our audits.

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

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Beacon/PW
Kendall LLC at December 31, 1999 and 1998, and the consolidated results of its
operations and its cash flows for the year ended December 31, 1999 and for the
period from April 16, 1998 (inception) to December 31, 1998, in conformity with
accounting principles generally accepted in the United States. Also in our
opinion, the related financial statement schedule, when considered in relation
to the basic financial statements taken as a whole, presents fairly in all
material respects the information set forth therein.

                               DECEMBER 31, 1999

                             (DOLLARS IN THOUSANDS)

1. ORGANIZATION

    Beacon/PW Kendall LLC ("the Company") was formed on April 16, 1998 as a
Delaware limited liability company. The members of the Company are Beacon

Members holds a fifty percent economic interest in the Company and each made a
$63,507 equity contribution. Beacon Capital Partners, L.P. is the managing
member of the Company. Beacon Capital Partners, L.P. and PW Acquisitions IX, LLC
made their initial equity contributions on May 1, 1998 and May 20, 1998,

1998 has been allocated one hundred percent to Beacon Capital Partners, L.P.

    The Company is the sole member of One Kendall LLC. One Kendall LLC has
invested in certain land, buildings, and improvements in Cambridge,
Massachusetts.

    The Company is the managing member of Kendall Athenaeum LLC, holding a 99%
economic interest. Kendall Athenaeum LLC and the Company are the members of
Cambridge Athenaeum LLC, holding 1% and 99% economic interests, respectively.
Kendall Athenaeum LLC is the managing member of Cambridge Athenaeum LLC.

    Collectively, the Company's land, building and improvements comprise an

Athenaeum Portfolio. In April 1999, Beacon Capital Partners, L.P. announced that
it was offering for sale a portfolio of properties located in Cambridge,
Massachusetts, that included The Athenaeum Portfolio. The portfolio of
properties for sale has been taken off the market and the Company is currently
pursuing a refinancing of The Athenaeum Portfolio.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF ACCOUNTING

    The accompanying consolidated financial statements are prepared in
accordance with generally accepted accounting principles and include the
accounts of the Company, its wholly-owned subsidiary One Kendall LLC and its
direct and indirect majority-owned subsidiaries, Kendall Athenaeum LLC, and
Cambridge Athenaeum LLC. The Company consolidates all wholly-owned subsidiaries
and those majority-owned subsidiaries in which it exercises control. All
significant intercompany transactions and balances have been eliminated in
consolidation.

USE OF ESTIMATES

    The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amount of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements. Actual results could differ from those estimates.

REAL ESTATE

    Buildings are recorded at cost and are depreciated on the straight-line
method over their estimated useful life of forty years. The cost of buildings
includes the purchase price of the property, legal fees, and

                                      F-24

                             (DOLLARS IN THOUSANDS)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
other acquisition costs. Acquisition costs associated with the purchase of new
property consist of third party costs and have been capitalized to the
appropriate assets.

    The Company measures impairment in accordance with FASB Statement No. 121,
ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE
DISPOSED OF, which requires impairment losses to be recorded on specific
long-lived assets used in operations where indicators of impairment are present
and the undiscounted cash flows estimated to be generated by those assets are
less than the assets' carrying amount.

    Equipment is depreciated using the straight-line method over their expected
useful lives of three to ten years.

DEFERRED FINANCING AND LEASING COSTS

    Deferred financing costs are fees and costs incurred to obtain long-term
financing and are being amortized over the term of the respective loan. Deferred
leasing costs are fees and costs incurred in the successful negotiation of
leases, including brokerage, legal and other costs and are being amortized on a
straight-line basis over the terms of the respective leases.

CASH AND CASH EQUIVALENTS

    Cash and cash equivalents consist of short-term, highly liquid assets with
original maturities of three months or less from the date of purchase.

RESTRICTED CASH

    Restricted cash consists of funds held in escrow as required by the lender
to satisfy real estate taxes and various other expenses associated with the
operations of the properties.

FAIR VALUE OF FINANCIAL INSTRUMENTS

    The Company is required to disclose the fair values of financial instruments
for which it is practicable to estimate such fair value. The fair values of
financial instruments are estimates based upon market conditions and perceived
risks at December 31, 1999 and require varying degrees of management judgment.
The fair values of financial instruments presented may not be indicative of
amounts the Company could realize on the disposition of the financial
instruments.

    Cash, cash equivalents and restricted cash are carried at an amount, which
due to their nature, approximates fair value.

    The Company computes the fair value of its mortgage note payable based upon
the Cambridge Athenaeum LLC assets' discounted cash flows at a discount rate
that approximates the Company's effective borrowing rate. The Company has
determined that the fair value of its mortgage note approximates its carrying
value.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
REVENUE RECOGNITION

    Revenues are recognized when earned and the amounts can be reasonably
estimated on the accrual basis of accounting. Rental income from operating
leases is recognized on a straight-line basis over the life of the lease
agreements.

INCOME TAXES

    As limited liability companies, the Company and its consolidated
subsidiaries are deemed to be partnerships for federal and state income tax
purposes. As such, no provision or credit has been made in the accompanying
financial statements for federal or state income taxes since the Members are
required to include their respective share of profits or losses in their own tax
returns.

3. MORTGAGE NOTE PAYABLE

    The mortgage note payable represents a first mortgage note assumed with the
purchase of certain land, buildings and improvements by Cambridge Athenaeum LLC.
The first mortgage note is due January 11, 2027, with principal and interest
payments due monthly. The interest rate on the mortgage note is 8.485%. The net
book value of the mortgaged assets is $127,420 at December 31, 1999. Future
minimum principal payments due during the next five years and thereafter are as
