                            BOSTON PROPERTIES, INC.

                          (par value $.01 per share)


                              __________________

    
        This Prospectus relates to the possible offer and sale from time to time
of (i) up to 1,675,846 shares of common stock, par value $.01 per share ("Common
Stock"), of Boston Properties Inc. (the "Company") by a holder thereof (the
"Current Holder"), and (ii) up to 2,993,414 shares of Common Stock by a holder
thereof (the "Unitholder" and, collectively with the Current Holder, the
"Selling Stockholders"), if and to the extent that the Company elects to issue
such shares to the Unitholder to acquire common units of limited partnership
interests ("Units") in Boston Properties Limited Partnership, a Delaware limited
partnership, of which the Company is the sole general partner (the "Operating
Partnership"). Under the terms of the Second Amended and Restated Agreement of
Limited Partnership of the Operating Partnership, dated June 29, 1998 as amended
(the "Operating Partnership Agreement"), holders of Units have the right to
require the Operating Partnership to redeem their Units for cash, subject to
certain restrictions. However, in lieu of a cash redemption of Units, Boston
Properties, Inc. may elect to acquire any Units presented for redemption for an
equivalent number of shares of Common Stock. The registration of the shares of
Common Stock offered hereby (the "Shares") does not necessarily mean that (i)
the Current Holder will sell any or all of its Shares nor (ii) the Shares will
be issued by the Company in satisfaction of the Unitholder's redemption rights
or that, if issued by the Company, any of the Shares will be offered or sold by
the Unitholder. See "Plan of Distribution" and "Selling Stockholders." Each of
the Selling Stockholders, directly or through agents, dealers or underwriters
designated from time to time, may sell all or a portion of the shares of Common
Stock offered hereby from time to time on terms to be determined at the time of
sale. To the extent required, the specific shares of Common Stock to be sold,
the names of the Selling Stockholders, the respective purchase prices and public
offering prices, the names of any such agent, dealer or underwriter, and any
applicable commissions or discounts with respect to a particular offer will be
set forth in an accompanying prospectus supplement. See "Plan of Distribution."
Each Selling Stockholder reserves the sole right to accept and, together with
such Selling Stockholder's agents, dealers or underwriters from time to time, to
reject, in whole or in part, any proposed purchase of shares of Common Stock to
be made directly or through agents, dealers or underwriters.      

        The aggregate proceeds to the Selling Stockholders from the sale of the
shares of Common Stock offered hereby (the "Offering") will be the purchase
price of the shares of Common Stock sold less the aggregate agents' commissions
and underwriters' discounts, if any, and other expenses of issuance and
distribution to be borne by the Company. The Company will pay all of the
expenses of the Offering other than agents' commissions and underwriters'
discounts with respect to the shares of Common Stock offered hereby, and
transfer taxes, if any. The Company will not receive any proceeds from the sale
of the shares of Common Stock offered hereby by the Selling Stockholders.

        The Selling Stockholders and any agents, dealers or underwriters that
participate with the Selling Stockholders in the distribution of the shares of
Common Stock may be deemed to be "underwriters" within the meaning of the
Securities Act of 1933, as amended (the "Securities Act"), in which case any
commissions received by such agents, dealers or underwriters and any profit on
the resale of the shares of Common Stock purchased by them may be deemed
underwriting commissions or discounts under the Securities Act. See "Plan of
Distribution" for indemnification arrangements between the Company and the
Selling Stockholders.

        The Common Stock is listed on the New York Stock Exchange (the "NYSE")
under the symbol "BXP."

                                 RISK FACTORS

        "Safe Harbor" statement under the Private Securities Litigation Reform
Act of 1995: Certain materials filed or to be filed by the Company with the
Commission and incorporated by reference herein contain statements that are or
will be forward-looking, such as statements relating to acquisitions (including
related pro forma financial information) and other business development
activities, future capital expenditures, financing sources and availability and
the effects of regulations (including environmental regulation) and competition.
Such forward-looking information involves important risks and uncertainties that
could significantly affect anticipated results in the future and, accordingly,
such results may differ from those expressed in any forward-looking statements
incorporated by reference herein. These risks and uncertainties include, but are
not limited to, uncertainties affecting real estate businesses generally (such
as entry into new leases, renewals of leases and dependence on tenants' business
operations), risks relating to acquisition, construction and development
activities, possible environmental liabilities, risks relating to leverage and
debt service (including availability of financing terms acceptable to the
Company and sensitivity of the Company's operations to fluctuations in interest
rates), the potential for the use of borrowings to make distributions necessary
to qualify as a REIT, dependence on the primary markets in which the properties
are located, the existence of complex regulations relating to status as a REIT
and the adverse consequences of the failure to qualify as a REIT and the
potential adverse impact of market interest rates on the market prices for the
Company's Common Stock.

        All references in this Prospectus to the "Company" refer to Boston
Properties, Inc. and its subsidiaries, including the Operating Partnership.


THE COMPANY MAY NOT ACHIEVE EXPECTED RETURNS ON PROPERTY ACQUISITIONS

        The Company intends to continue to investigate and pursue acquisitions
of properties and portfolios of properties, including large portfolios that
could significantly increase the size of the Company and alter its capital
structure. There can be no assurance that the Company will be able to assimilate
acquisitions of properties, and in particular acquisitions of portfolios of
properties, or achieve the Company's intended return on investment.

THE COMPANY'S INVESTMENTS IN PROPERTY DEVELOPMENT MAY NOT YIELD EXPECTED RETURNS

        The Company intends to continue to pursue the development of properties
to supplement the properties currently owned by the Operating Partnership or in
which it holds an interest (each a "Property" and collectively, the
"Properties"). To the extent that the Company engages in such development
activities, it will be subject to the risks normally associated with such
activities. Such risks include, without limitation, risks relating to the
availability and timely receipt of zoning, land use, building, occupancy, and
other regulatory approvals, the cost and timely completion of construction
(including risks from causes beyond the Company's control, such as weather,
labor conditions or material shortages) and the availability of construction
financing on favorable terms. These risks could result in substantial
unanticipated delays or expense and, under certain circumstances, could prevent
completion of development activities once undertaken, any of which could have an
adverse effect on the financial condition and results of operations of the
Company and on the amount of cash available for distribution to stockholders.

THE COMPANY RELIES ON KEY PERSONNEL WHOSE CONTINUED SERVICE IS NOT GUARANTEED

        The Company is dependent on the efforts of Mortimer B. Zuckerman and
Edward H. Linde and other senior management personnel. Messrs. Zuckerman and
Linde in particular have national reputations which aid the Company in
negotiations with lenders and in having investment opportunities brought to the
Company. The other executive officers of the Company who serve as managers of
the Company's offices have strong regional reputations which aid the Company in
identifying opportunities, or having opportunities brought to the Company, and
in negotiating with tenants or build-to-suit prospects. While the Company
believes that it could find replacements for these key executives, the loss of
their services could have a material adverse effect on the 

                                       4

 
     
operations of the Company in that the extent and nature of the Company's
relationships with lenders and prospective tenants and with persons in the
industry who may have access to investment opportunities would be diminished.
While Mr. Linde and the other executive officers have employment agreements with
the Company pursuant to which they have agreed to devote substantially all of
their business time to the business and affairs of the Company and to not have
substantial outside business interests, this can serve as no guarantee that they
will remain with the Company for any specified term. Mr. Zuckerman, who has
significant outside business interests, including serving as Chairman of the
Board of Directors of U.S. News & World Report, The Atlantic Monthly, the New
York Daily News and Applied Graphics Technologies and as a member of the Board
of Directors of Snyder Communications, does not have an employment agreement
with the Company and serves as a non-executive officer of the Company with the
title "Chairman of the Board of Directors." Mr. Zuckerman has historically
devoted a significant portion of his business time to the affairs of the
Company, although over the last twenty years less than a majority of his
business time, in the aggregate, has been spent on the Company's affairs.
Although Mr. Zuckerman cannot assure the Company that he will continue to devote
any specific portion of his time to the Company and has therefore declined to
enter into an employment agreement with the Company, Mr. Zuckerman has no
present commitments inconsistent with his current level of involvement with the
Company.      

THE COMPANY'S PERFORMANCE AND VALUE ARE SUBJECT TO RISKS ASSOCIATED WITH THE
REAL ESTATE INDUSTRY

        Lease expirations could adversely affect the Company's cash flow. The
Company will be subject to the risks that, upon expiration, leases for space may
not be renewed, the space may not be re-leased, or the terms of renewal or
re-lease (including the cost of required renovations or concessions to tenants)
may be less favorable than current lease terms. If the Company were unable to
re-lease substantial amounts of vacant space promptly, if the rental rates upon
such re-lease were significantly lower than expected, or if reserves for costs
of re-leasing proved inadequate, the cash flow to the Company would be decreased
and the Company's ability to make distributions to stockholders would be
adversely affected.

    
        Hotel operating risks could adversely affect the Company's cash flow.
The Company's hotel properties are subject to all operating risks common to the
hotel industry. These risks include, among other things: (i) competition for
guests from other hotels, a number of which may have greater marketing and
financial resources than the Company; (ii) increases in operating costs due to
inflation and other factors, which increases may not have been offset in recent
years, and may not be offset in the future by increased room rates; (iii)
dependence on business and commercial travelers and tourism, which business may
fluctuate and be seasonal; (iv) increases in energy costs and other expenses of
travel, which may deter travelers; and (v) adverse effects of general and local
economic conditions. These factors could adversely affect the Company's ability
to make distributions to stockholders.      

        Acquisitions risks could adversely affect the Company. There can be no
assurance that the Company will be able to implement its investment strategies
successfully or that its property portfolio will expand at all, or at any
specified rate or to any specified size. In addition, investment in additional
real estate assets is subject to a number of risks. In particular, investments
are expected to be financed from time to time with funds drawn under its line of
credit, which would subject the Company to the risks described under "The
Company's Use of Debt to Finance Acquisitions and Developments Could Adversely
Affect the Company." To the extent that the Company elects to invest in
additional markets, it also will be subject to the risks associated with
investment in new markets, with which management may have relatively little
experience and familiarity. Investment in additional real estate assets also
entails the other risks associated with real estate investment generally.

        Uncontrollable factors affecting Properties performance and value could
produce lower returns. The economic performance and value of the Company's real
estate assets is 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.
Currently, the Properties are located primarily in six markets: Greater Boston;
Greater Washington, D.C.; midtown Manhattan; Baltimore, Maryland; Richmond,
Virginia; and Princeton/New Brunswick, New Jersey. The economic condition of
each of such markets may be dependent on one or more industries. An economic
downturn in one of these industry sectors may have an

                                       5

 
adverse effect on the Company's performance in such market. Local real estate
market conditions may include a large supply of competing space and competition
for tenants, including competition based on rental rates, attractiveness and
location of the property and quality of maintenance, insurance and management
services. Economic and market conditions may impact the ability of tenants to
make lease payments. In addition, other factors may adversely affect the
performance and value of a property, including changes in laws and governmental
regulations (including those governing usage, zoning and taxes), changes in
interest rates and the availability of financing. If the Properties do not
generate sufficient income to meet operating expenses, including future debt
service, the Company's income and ability to make distributions to its
stockholders will be adversely affected.

        Illiquidity of real estate investments could adversely affect the
Company's financial condition. Because real estate investments are relatively
illiquid, the Company's ability to vary its portfolio promptly in response to
economic or other conditions will be limited. In addition, certain significant
expenditures, such as debt service (if any), real estate taxes, and operating
and maintenance costs, generally are not reduced in circumstances resulting in a
reduction in income from the investment. The foregoing and any other factor or
event that would impede the ability of the Company to respond to adverse changes
in the performance of its investments could have an adverse effect on the
Company's financial condition and results of operations.

        Liability for environmental matters could adversely affect the Company's
financial condition. Under various federal, state and local laws, ordinances and
regulations, an owner or operator of real property may become liable for the
costs of removal or remediation of certain hazardous or toxic substances. Such
liability may be imposed without regard to whether the owner or operator knew
of, or was responsible for, the release of such substances. The presence of, or
the failure to remediate properly, such substances, when released, may adversely
affect the owner's ability to sell the affected real estate or to borrow using
such real estate as collateral. Such costs or liabilities could exceed the value
of the affected real estate.

        The cost of complying with the Americans with Disabilities Act could
adversely affect the Company's cash flow. The Americans with Disabilities Act
(the "ADA"), generally requires that public accommodations, including office
buildings, be made accessible to disabled persons. The Company believes that the
Properties are in substantial compliance with the ADA and that it will not be
required to make substantial capital expenditures to address the requirements of
the ADA. However, compliance with the ADA could require removal of access
barriers and noncompliance could result in imposition of fines by the federal
government or the award of damages to private litigants. If, pursuant to the
ADA, the Company were required to make substantial alterations in one or more of
the Properties, the Company's financial condition and results of operations, as
well as the amount of funds available for distribution to stockholders, could be
adversely affected.

        Uninsured losses could adversely affect the Company's cash flow. The
Company carries comprehensive liability, fire, flood, extended coverage and
rental loss insurance, as applicable, with respect to the Properties, with
policy specification and insured limits customarily carried for similar
properties. In the opinion of management, all of the Properties are adequately
insured. There are, however, certain types of losses (such as from wars or
catastrophic acts of nature) that may be either uninsurable or not economically
insurable. Any uninsured loss could result in both loss of cash flow from, and
asset value of, the affected Property.

        New owner's title insurance policies were not obtained in connection
with certain Properties acquired by the Operating Partnership at the time of the
Initial Public Offering. Prior to their acquisition by the Operating
Partnership, each of the Properties acquired at the completion of the Company's
initial public offering of Common Stock on June 23, 1997 (the "Initial
Offering") was insured by title insurance policies insuring the interests of the
Property-owning entities. Certain of these title insurance policies may continue
to benefit those Property-owning entities which remained after the completion of
the acquisition by the Operating Property. Nevertheless, each such title
insurance policy may be in an amount less than the current value of the
applicable Property. In the event of a loss with respect to a Property relating
to a title defect, the Company could lose both its capital invested in and
anticipated profits from such Property. With respect to Properties acquired
subsequent to the Company's Initial Offering, the Operating Partnership has
obtained title insurance policies for each such Property acquired.

                                       6

 
        Changes in tax and environmental laws could adversely affect the
Company's financial condition. Costs resulting from changes in real estate taxes
generally may be passed through to tenants and will not affect the Company.
Increases in income, service or transfer taxes, however, generally are not
passed through to tenants and may adversely affect the Company's results of
operations and the amount of funds available to make distributions to
stockholders. Similarly, changes in laws increasing the potential liability for
environmental conditions existing on properties or increasing the restrictions
on discharges or other conditions may result in significant unanticipated
expenditures, which would adversely affect the Company's financial condition and
results of operations and the amount of funds available for distribution to
stockholders.

THE COMPANY'S USE OF DEBT TO FINANCE ACQUISITIONS AND DEVELOPMENTS COULD
ADVERSELY AFFECT THE COMPANY

        The required repayment of debt or of interest thereon can adversely
affect the Company. The Company may incur variable rate indebtedness in the
future. Increases in interest rates on such indebtedness would increase the
Company's interest expense, which could adversely affect the Company's cash flow
and its ability to pay expected distributions to stockholders. The Company is
subject to risks normally associated with debt financing, including the risk
that the Company's cash flow will be insufficient to meet required payments of
principal and interest, the risk that any indebtedness will not be able to be
refinanced or that the terms of any such refinancing will not be as favorable as
the terms of such indebtedness.

        The Company's policy of no limitation on debt could adversely affect the
Company's cash flow. The Company does not have a policy limiting the amount of
debt that the Company may incur. Accordingly, the Company could become more
highly leveraged, resulting in an increase in debt service that could adversely
affect the Company's cash flow and, consequently, the amount available for
distribution to stockholders, and could increase the risk of default on the
Company's indebtedness.

FAILURE TO QUALIFY AS A REIT WOULD CAUSE THE COMPANY TO BE TAXED AS A 
CORPORATION

    
        The Company will be taxed as a corporation if it fails to qualify as a
REIT. The Company intends at all times to operate so as to qualify as a REIT
under the Internal Revenue Code of 1986, as amended (the "Code"). Although
management of the Company believes that it is organized and will continue
to operate in such a manner, no assurance can be given that the Company
qualifies or that the Company will continue to qualify as a REIT in the future.
Qualification as a REIT, however, involves the application of highly technical
and complex Code provisions as to which there are only limited judicial and
administrative interpretations. Certain facts and circumstances which may be
wholly or partially beyond the Company's control may affect its ability to
qualify as a REIT. In addition, no assurance can be given that future
legislation, new regulations, administrative interpretations or court decisions
will not significantly change the tax laws (or the application thereof) with
respect to qualification as a REIT for Federal income tax purposes or the
Federal income tax consequences of such qualification.      

        If, in any taxable year, the Company were to fail to qualify as a REIT
for Federal income tax purposes, it would not be allowed a deduction for
distributions to stockholders in computing taxable income and would be subject
to Federal income tax (including any applicable alternative minimum tax) on its
taxable income at regular corporate rates. In addition, unless entitled to
relief under certain statutory provisions, the Company would be disqualified
from treatment as a REIT for Federal income tax purposes for the four taxable
years following the year during which qualification is lost. The additional tax
liability resulting from the failure to qualify as a REIT would significantly
reduce the amount of funds available for distribution to stockholders. In
addition, the Company would no longer be required to make distributions to
stockholders. Although the Company intends to continue to operate in a manner
designed to permit it to qualify as a REIT for Federal income tax purposes, it
is possible that future economic, market, legal, tax or other events or
circumstances could cause it to fail to so qualify. See "Federal Income Tax
Considerations."

        To qualify as a REIT the Company will need to maintain a certain level
of distributions. To maintain its status as a REIT for Federal income tax
purposes, the Company generally will be required each year to distribute to its
stockholders at least 95% of its taxable income. In addition, the Company will
be subject to 

                                       7

 
a 4% nondeductible excise tax on the amount, if any, by which certain
distributions paid by it with respect to any calendar year are less than the sum
of 85% of its ordinary income for such calendar year, 95% of its capital gain
net income other than such capital gain net income which the REIT elects to
retain and pay tax on for the calendar year and any amount of such income that
was not distributed in prior years. The Company may be required, under certain
circumstances, to accrue as income for tax purposes interest, rent and other
items treated as earned for tax purposes but not yet received. In addition, the
Company may be required not to accrue as expenses for tax purposes certain items
which actually have been paid. It is also possible that the Company could
realize income, such as income from cancellation of indebtedness, which is not
accompanied by cash proceeds. See "Federal Income Tax Considerations."

        The Company intends to make distributions to stockholders sufficient to
comply with the 95% distribution requirement and to avoid the 4% nondeductible
excise tax described above. No assurances can be given, however, that the
Company will satisfy these requirements.

        Other Tax Liabilities. Even if it qualifies as a REIT for federal income
tax purposes, the Company may, and certain of its subsidiaries will, be subject
to certain Federal, state and local taxes on their income and property. See
"Federal Income Tax Consequences--State and Local Tax."

THE ABILITY OF STOCKHOLDERS TO CONTROL THE POLICIES OF THE COMPANY AND EFFECT A 
CHANGE OF CONTROL OF THE COMPANY IS LIMITED

        Stockholder approval is not required to change policies of the Company.
The Company's operating and financial policies, including its policies with
respect to acquisitions, growth, operations, indebtedness, capitalization and
distributions, are determined by the Company's board of directors (the "Board of
Directors"). Accordingly, stockholders have little direct control over the
Company's policies.

        Stockholder approval is not required to engage in investment activity.
The Company expects to continue to acquire additional real estate assets
pursuant to its investment strategies and consistent with its investment
policies. The stockholders of the Company will generally not be entitled to
receive historical financial statements regarding, or to vote on, any such
acquisition and, instead, will be required to rely entirely on the decisions of
management (although in the case of acquisitions that are material, the Company
will, as required by Federal securities law, provide financial information
regarding the acquisition in public filings.)

        Stock ownership limit in the Certificate could inhibit changes in
control. In order to maintain its qualification as a REIT for Federal income tax
purposes, not more than 50% in value of the outstanding stock of the Company may
be owned, directly or indirectly, by five or fewer individuals (as defined in
the Code to include certain entities). See "Federal Income Tax Considerations."
In order to facilitate maintenance of its qualification as a REIT for Federal
income tax purposes, and to otherwise address concerns relating to concentration
of capital stock ownership, the Company generally has prohibited ownership,
directly or by virtue of the attribution provisions of the Code, by any single
stockholder (which does not include certain pension plans or mutual funds) of
more than 6.6% of the issued and outstanding shares of the Company's Common
Stock (the "Ownership Limit"). The Board of Directors may waive or modify the
Ownership Limit with respect to one or more persons if it is satisfied, based
upon the advice of tax counsel, that ownership in excess of this limit will not
jeopardize the Company's status as a REIT for Federal income tax purposes. The
Ownership Limit may have the effect of inhibiting or impeding a change in
control and, therefore, could adversely affect the stockholders' ability to
realize a premium over the then-prevailing market price for the Common Stock in
connection with such a transaction.

    
        Provisions in the Certificate and the Bylaws and in the Operating
Partnership Agreement could prevent acquisitions and changes in control. Certain
provisions of the Company's Certificate and the Amended and Restated Bylaws (the
"Bylaws") the Operating Partnership Agreement may have the effect of inhibiting
a third party from making an acquisition proposal for the Company or of impeding
a change in control of the Company under circumstances that could otherwise
provide the holders of      
                                       8

 
shares of Common Stock with the opportunity to realize a premium on the then-
prevailing market price of such shares. The Ownership Limit described in the
preceding paragraph also may have the effect of precluding acquisition of
control of the Company even if such a change in control were in the best
interests of some, or a majority, of the Company's stockholders. In addition,
the Board of Directors has been divided into three classes, with directors of a
given class chosen for three-year terms upon expiration of the terms of the
members of that class. The staggered terms of the members of the Board of
Directors may adversely affect the stockholder's ability to effect a change in
control of the Company, even if such a change in control were in the best
interests of some, or a majority, of the Company's stockholders. The Certificate
authorizes the Board of Directors to issue shares of preferred stock ("Preferred
Stock") in series and to establish the rights and preferences of any series of
Preferred Stock so issued. See "Description of Capital Stock--Preferred Stock."
The issuance of Preferred Stock also could have the effect of delaying or
preventing a change in control of the Company, even if such a change in control
were in the best interests of some, or a majority, of the Company's
stockholders. The Company authorized the issuance of a series of preferred stock
in connection with the adoption of a shareholder rights plan. See "Description
of Capital Stock--Shareholder Rights Agreement."

        The Operating Partnership Agreement provides that the Company may not
generally engage in any merger, consolidation or other combination with or into
another person or sale of all or substantially all of its assets, or any
reclassification, or any recapitalization or change of outstanding shares of
Common Stock (a "Business Combination"), unless the holders of Units will
receive, or have the opportunity to receive, the same consideration per Unit as
holders of Common Stock receive per share of Common Stock in the transaction; if
holders of Units will not be treated in such manner in connection with a
proposed Business Combination, the Company may not engage in such transaction
unless limited partners (other than the Company) holding at least 75% of the
Units held by limited partners vote to approve the Business Combination. In
addition, the Company, as general partner of the Operating Partnership, has
agreed in the Operating Partnership Agreement with the limited partners that the
Company will not consummate a Business Combination in which the Company
conducted a vote of the stockholders unless the matter would have been approved
had holders of Units been able to vote together with the stockholders on the
transaction. The foregoing provisions of the Operating Partnership Agreement
would under no circumstances enable or require the Company to engage in a
Business Combination which required the approval of the Company's stockholders
if the Company's stockholders did not in fact give the requisite approval.
Rather, if the Company's stockholders did approve a Business Combination, the
Company would not consummate the transaction unless (i) the Company as general
partner first conducts a vote of holders of Units (including the Company) on the
matter, (ii) the Company votes the Units held by it in the same proportion as
the stockholders of the Company voted on the matter at the stockholder vote, and
(iii) the result of such vote of the Unit holders (including the proportionate
vote of the Company's Units) is that had such vote been a vote of stockholders,
the Business Combination would have been approved by the stockholders. As a
result of these provisions of the Operating Partnership, a third party may be
inhibited from making an acquisition proposal that it would otherwise make, or
the Company, despite having the requisite authority under its Certificate, may
be prohibited from engaging in a proposed Business Combination.

        Shareholder Rights Agreement could inhibit changes in control. The
Company adopted a Shareholder Rights Agreement (the "Shareholder Rights
Agreement"). Under the terms of the Shareholder Rights Agreement, in general, if
a person or group acquires more than 15% of the outstanding shares of Common
Stock (an "Acquiring Person"), all other stockholders will have the right to
purchase securities from the Company at a discount to such securities' fair
market value, thus causing substantial dilution to the Acquiring Person. The
Shareholder Rights Agreement may have the effect of inhibiting or impeding a
change in control and, therefore, could adversely affect the stockholders'
ability to realize a premium over the then-prevailing market price for the
Common Stock in connection with such a transaction. In addition, since the Board
of Directors of the Company can prevent the Shareholder Rights Agreement from
operating in the event the Board of Directors approves of an Acquiring Person,
the Shareholder Rights Agreement gives the Board of Directors significant
discretion over whether a potential acquiror's efforts to acquire a large
interest in the Company will be successful. See "Description of Capital
Stock--Shareholder Rights Agreement."

                                       9

 
        Certain provisions of Delaware law could inhibit acquisitions and
changes in control. Certain provisions of the Delaware General Corporation Law
(the "DGCL") also may have the effect of inhibiting a third party from making an
acquisition proposal for the Company or of impeding a change in control of the
Company under circumstances that otherwise could provide the holders of shares
of Common Stock with the opportunity to realize a premium over the
then-prevailing market price of such shares.

CONFLICTS OF INTEREST EXIST BETWEEN THE COMPANY AND CERTAIN HOLDERS OF UNITS OF 
THE OPERATING PARTNERSHIP IN CONNECTION WITH THE OPERATION OF THE COMPANY

        For a period of time, sales of Properties and repayment of indebtedness
will have different effects on holders of Units than on stockholders. Certain
holders of Units, including Messrs. Zuckerman and Linde, will incur adverse tax
consequences upon the sale of certain of the Properties and on the repayment of
indebtedness which are different from the tax consequences to the Company and
persons who purchase shares of Common Stock in an offering. Consequently, such
holders may have different objectives regarding the appropriate pricing and
timing of any such sale or repayment of indebtedness. While the Company has the
exclusive authority under the Operating Partnership Agreement to determine
whether, when, and on what terms to sell a Property (subject, in the case of
certain Properties, to contractual commitments described below) or when to
refinance or repay indebtedness, any such decision would require the approval of
the Board of Directors. As directors and executive officers of the Company,
Messrs. Zuckerman and Linde have substantial influence with respect to any such
decision, and such influence could be exercised in a manner inconsistent with
the interests of some, or a majority, of the Company's stockholders, including
in a manner which could prevent completion of a sale of a Property or the
repayment of indebtedness.

        The Operating Partnership Agreement provides that the Operating
Partnership may not sell or otherwise transfer certain Properties in a taxable
transaction prior to specified dates without the prior consent of Messrs.
Zuckerman and Linde. The Operating Partnership is not, however, required to
obtain the aforementioned consent from Messrs. Zuckerman or Linde if, at any
time during such applicable period, each of Messrs. Zuckerman and Linde do not
continue to hold at least 30% of Units issued to him in connection with the
Initial Offering. The Operating Partnership has also entered into agreements
providing Messrs. Zuckerman and Linde and others with the right to guarantee
additional and/or substitute indebtedness of the Company in the event that
certain other indebtedness is repaid or reduced. The Company has entered into
similar agreements with respect to other Properties it has acquired in exchange
for Units.

        Messrs. Zuckerman and Linde will continue to engage in other activities.
Messrs. Zuckerman and Linde have a broad and varied range of investment
interests. It is possible that companies in which one or both of Messrs.
Zuckerman and Linde has or may acquire an interest, and which are not directly
involved in real estate investment activities, will be owners of real property
and will acquire real property in the future. However, pursuant to Mr. Linde's
employment agreement and Mr. Zuckerman's non-compete agreement with the Company,
Messrs. Zuckerman and Linde will not, in general, have management control over
such companies and, therefore, they may not be able to prevent one or more such
companies from engaging in activities that are in competition with activities of
the Company.

POSSIBLE ADVERSE IMPACT OF MARKET CONDITIONS ON MARKET PRICE

        The market value of the Common Stock could be substantially affected by
general market conditions, including changes in interest rates. An increase in
market interest rates may lead purchasers of the Common Stock to demand a higher
annual yield, which could adversely affect the market price of the outstanding
Common Stock. Moreover, numerous other factors such as government regulatory
action and changes in tax laws could have a significant impact on the future
market price of the Common Stock.

                                  THE COMPANY

        The Company is one of the largest owners and developers of office
properties in the United States, with a significant presence in Greater Boston,
Greater Washington, D.C., midtown Manhattan, Baltimore, Maryland, Richmond,
Virginia and Princeton/East Brunswick, New Jersey. The Company owns or holds an
interest in 113 properties (the "Properties"). The Properties aggregate
approximately 21.2 million square feet. The Company is a self-administered and
self-managed real estate investment trust (a "REIT") and has elected to be
treated as a REIT under the Code beginning with its taxable year ended December
31, 1997. The Company's Common Stock is listed on the NYSE under the symbol
"BXP."

        The Company was formed to succeed to the real estate development,
redevelopment, acquisition, management, operating and leasing businesses
associated with the predecessor company founded by Messrs. Zuckerman and Linde
in 1970. Substantially all of the Company's business is conducted through, and
all of the Company's interests in its properties are held by, the Operating
Partnership. The Company is the sole general partner of the Operating
Partnership, and through its ownership of a general and limited partnership
interest in the Operating Partnership, the Company is currently a 71.8% economic
owner of the Operating Partnership (this structure is commonly referred to as an
umbrella partnership REIT or "UPREIT").

        The Company is a full-service real estate company, with substantial
in-house expertise and resources in acquisitions, development, financing,
construction management, property management, marketing, leasing, accounting,
tax and legal services. The Company's Common Stock has been traded on the NYSE
since the completion of the Initial Offering in June 1997. The Company's
headquarters are located at 8 Arlington Street, Boston, Massachusetts 02116 and
its telephone number is (617) 859-2600. In addition, the Company has regional
offices at the U.S. International Trade Commission Building at 500 E Street, SW,
Washington, D.C. 20024 and at 599 Lexington Avenue, New York, New York 10002.

                         DESCRIPTION OF CAPITAL STOCK

        The description set forth below does not purport to be complete and is
qualified in its entirety by reference to the Company's Certificate and Bylaws,
copies of which are exhibits to the Registration Statement of which this
Prospectus is a part.

GENERAL

    
        Under the Certificate, the Company has authority to issue 450 million
shares of stock, consisting of 250 million shares of Common Stock, 150 million
shares of Excess Stock, par value $0.01 per share (the "Excess Stock"), and 50
million shares of preferred stock, par value $0.01 per share (the "Preferred
Stock"). At August 17, 1998, the Company had outstanding 63,516,785 shares of
Common Stock. All shares of Common Stock will, when issued, be duly authorized,
fully paid and nonassessable.       

COMMON STOCK

        Subject to the preferential rights of any other shares or series of
capital stock and to the provisions of the Certificate regarding Excess Stock,
holders of Common Stock will be entitled to receive dividends on Common Stock
if, as and when authorized and declared by the Board of Directors out of assets
legally available therefor and to share ratably in the assets of the Company
legally available for distribution to its stockholders in the event of its
liquidation, dissolution or winding-up after payment of, or adequate provision
for, all known debts and liabilities of the Company.

        Subject to the provisions of the Certificate regarding Excess Stock,
each outstanding share of Common Stock entitles the holder to one vote on all
matters submitted to a vote of stockholders, including the election of
Directors, and, except as otherwise required by law or except as provided with
respect to any other class or series of capital stock, the holders of Common
Stock will possess exclusive voting power. There is no cumulative voting in the
election of Directors, which means that the holders of a majority of the
outstanding 

                                       11

 
shares of Common Stock can elect all of the Directors then standing for
election, and the holders of the remaining Common Stock will not be able to
elect any Director.

     Holders of Common Stock have no conversion, sinking fund or redemption
rights, or preemptive rights to subscribe for any securities of the Company.

     The Company intends to furnish its stockholders with annual reports
containing audited consolidated financial statements and an opinion thereon
expressed by an independent public accounting firm and quarterly reports for the
first three quarters of each fiscal year containing unaudited financial
information.

     Subject to the provisions of the Certificate regarding Excess Stock, all
Common Stock has equal dividend, distribution, liquidation and other rights, and
has no preference, appraisal (except as provided by the DGCL) or exchange
rights.

     Pursuant to the DGCL, a merger or consolidation involving the Company
generally requires the approval of a majority of the outstanding shares entitled
to vote on such a matter. However, subsection 251(f) of the DGCL provides that
no vote of a corporation's stockholders is required to authorize a merger in
which such corporation is the surviving corporation following the merger and:
(i) the certificate of incorporation is not amended in any respect by the
merger, (ii) each share of stock outstanding prior to the merger is to be an
identical share of stock after the effective date of the merger and (iii) any
shares of common stock (together with any other securities convertible into
shares of common stock) to be issued or delivered under the plan of merger in
the aggregate amount to no more than 20% of the number of shares of common stock
outstanding immediately prior to the effective date of the merger.

     For the Company to qualify as a REIT under the Code, not more than 50%
in value of its outstanding capital stock may be owned, directly or indirectly,
by five or fewer individuals (as defined in the Code to include certain
entities) during the last half of a taxable year. To assist the Company in
meeting this requirement, the Company may take certain actions to limit the
beneficial ownership, directly or indirectly, by a single person of the
Company's outstanding equity securities. See "Restrictions on Transfer."

PREFERRED STOCK

     With respect to the Preferred Stock, the Certificate authorizes the
directors to set or change the preferences, conversion or other rights, voting
powers, restrictions, limitations as to distributions, qualifications or terms
or conditions of redemption of such stock. The Preferred Stock will, when
issued, be fully paid and nonassessable and will have no preemptive rights.
Because the Board of Directors of the Company has the power to establish the
preferences and rights of each class or series of Preferred Stock, the Board of
Directors of the Company may afford the holders of any series or class of
Preferred Stock preferences, powers and rights, voting or otherwise, senior to
the rights of holders of shares of Common Stock. The issuance or prospect of
issuance of Preferred Stock could have the effect of delaying or preventing a
change in control of the Company.

SHAREHOLDER RIGHTS AGREEMENT

     On June 16, 1997, the Board of Directors adopted the Shareholder Rights
Agreement. Under such plan, one right is attached to each outstanding share of
Common Stock, and one right will be attached to each share of Common Stock
hereafter issued. Each right entitles the holder to purchase, under certain
conditions, one one-thousandth of a share of Series E Junior Participating
Cumulative Preferred Stock of the Company for $100.00. The rights may also,
under certain conditions, entitle the holders to receive Common Stock, or common
stock of an entity acquiring the Company, or other consideration, each having a
value equal to twice the exercise price of each right ($200.00). The Company has
designated 200,000 shares as Series E Junior Participating Cumulative Preferred
Stock and has reserved such shares for issuance under the Shareholder Rights
Agreement. The rights are redeemable by the Company at a price of $.001 per
right. If not exercised or redeemed, all rights expire on June 16, 2007. The
description and terms of the rights are set forth in a Shareholder Rights
Agreement between the Company and BankBoston, N.A. 

                                       12

 
TRANSFER AGENT

     The transfer agent and registrar for the Common Stock is BankBoston, N.A.


                           RESTRICTIONS ON TRANSFER

     In order for the Company to qualify as a REIT under the Code, among other
things, not more than 50% in value of its outstanding capital stock may be
owned, directly or indirectly, by five or fewer individuals (defined in the Code
to include certain entities) during the last half of a taxable year (other than
the first year) (the "Five or Fewer Requirement"), and such shares of capital
stock must be beneficially owned by 100 or more persons during at least 335 days
of a taxable year of 12 months (other than the first year) or during a
proportionate part of a shorter taxable year. In order to protect the Company
against the risk of losing its status as a REIT and to otherwise protect the
Company from the consequences of a concentration of ownership among its
stockholders, the Certificate, subject to certain exceptions, provides that no
single person (which includes any "group" of persons) (other than the "Related
Parties," as defined below and certain "Look-Through Entities," as defined
below), may "beneficially own" more than 6.6% (the "Ownership Limit") of the
aggregate number of outstanding shares of any class or series of capital stock.
Under the Certificate, a person generally "beneficially owns" shares if (i) such
person has direct ownership of such shares, (ii) such person has indirect
ownership of such shares taking into account the constructive ownership rules of
Section 544 of the Code, as modified by Section 856(h)(1)(B) of the Code, or
(iii) such person would be deemed to "beneficially own" such shares pursuant to
Rule 13d-3 under the Exchange Act. A Related Party, however, will not be deemed
to beneficially own shares by virtue of clause (iii) of the preceding sentence
and a "group" of which a Related Party is a member will generally not have
attributed to the group's beneficial ownership any shares beneficially owned by
such Related Party. Each of Mr. Zuckerman and his respective heirs, legatees and
devises, and any other person whose beneficial ownership of shares of Common
Stock would be attributed under the Code to Mr. Zuckerman, is a "Related Party,"
and such persons are subject to a "Related Party Ownership Limit" of 15%, such
that none of such persons shall be deemed to beneficially own shares in excess
of the Ownership Limit unless, in the aggregate, such persons own shares of any
class or series of capital stock in excess of 15% of the number of shares of
such class or series outstanding. A similar Related Party Ownership Limit is
applied to Mr. Linde and persons with a similar relationship to Mr. Linde, all
of whom are also Related Parties under the Certificate. The Certificate provides
that pension plans described in Section 401(a) of the Code and mutual funds
registered under the Investment Company Act of 1940 ("Look-Through Entities")
are subject to a 15% "Look-Through Ownership Limit." Pension plans and mutual
funds are among the entities that are not treated as holders of stock under the
Five or Fewer Requirement and the beneficial owners of such entities will be
counted as holders for this purpose. Any transfer of shares of capital stock or
of any security convertible into shares of capital stock that would create a
direct or indirect ownership of shares of capital stock in excess of the
Ownership Limit, the Look-Through Ownership Limit or the Related Party Ownership
Limit, as applicable, or that would result in the disqualification of the
Company as a REIT, including any transfer that results in the shares of capital
stock being owned by fewer than 100 persons or results in the Company being
"closely held" within the meaning of Section 856(h) of the Code or results in
the Company constructively owning 10% or more of the ownership interests in a
tenant of the Company within the meaning of Section 318 of the Code as modified
by Section 856(d)(5) of the Code, shall be null and void, and the intended
transferee will acquire no rights to the shares of capital stock. The foregoing
restrictions on transferability and ownership will not apply if the Board of
Directors determines that it is no longer in the best interests of the Company
to attempt to qualify, or to continue to qualify, as a REIT. The Board of
Directors may, in its sole discretion, waive the Ownership Limit, the
Look-Through Ownership Limit and the Related Party Ownership Limit if evidence
satisfactory to the Board of Directors is presented that the changes in
ownership will not jeopardize the Company's REIT status and the Board of
Directors otherwise decides that such action is in the best interest of the
Company.

     If any purported transfer of capital stock of the Company or any other
event would otherwise result in any person violating the Ownership Limit, the
Look-Through Ownership Limit or the Related Party Limit, as applicable, or the
Certificate, then any such purported transfer will be void and of no force or
effect with 

                                       13

 
respect to the purported transferee (the "Prohibited Transferee") as
to that number of shares in excess of the applicable Limit and the Prohibited
Transferee shall acquire no right or interest (or, in the case of any event
other than a purported transfer, the person or entity holding record title to
any such shares in excess of the applicable Limit (the "Prohibited Owner") shall
cease to own any right or interest) in such excess shares. Any such excess
shares described above will be converted automatically into an equal number of
shares of Excess Stock (the "Excess Shares") and transferred automatically, by
operation of law, to a trust, the beneficiary of which will be a qualified
charitable organization selected by the Company (the "Beneficiary"). Such
automatic transfer shall be deemed to be effective as of the close of business
on the Trading Day (as defined in the Certificate) prior to the date of such
violative transfer. As soon as practical after the transfer of shares to the
trust, the trustee of the trust (who shall be designated by the Company and be
unaffiliated with the Company and any Prohibited Transferee or Prohibited Owner)
will be required to sell such Excess Shares to a person or entity who could own
such shares without violating the applicable Limit, and distribute to the
Prohibited Transferee an amount equal to the lesser of the price paid by the
Prohibited Transferee for such Excess Shares or the sales proceeds received by
the trust for such Excess Shares. In the case of any Excess Shares resulting
from any event other than a transfer, or from a transfer for no consideration
(such as a gift), the trustee will be required to sell such Excess Shares to a
qualified person or entity and distribute to the Prohibited Owner an amount
equal to the lesser of the fair market value of such Excess Shares as of the
date of such event or the sales proceeds received by the trust for such Excess
Shares. In either case, any proceeds in excess of the amount distributable to
the Prohibited Transferee or Prohibited Owner, as applicable, will be
distributed to the Beneficiary. Prior to a sale of any such Excess Shares by the
trust, the trustee will be entitled to receive in trust for the Beneficiary, all
dividends and other distributions paid by the Company with respect to such
Excess Shares.

     In addition, shares of stock of the Company held in the trust shall be
deemed to have been offered for sale to the Company, or its designee, at a price
per share equal to the lesser of (i) the price per share in the transaction that
resulted in such transfer to the trust (or, in the case of a devise or gift, the
market price at the time of such devise or gift) and (ii) the market price on
the date the Company, or its designee, accepts such offer.
 The Company shall have the right to accept such offer for a period of 90 days.
Upon such a sale to the Company, the interest of the Beneficiary in the shares
sold shall terminate and the trustee shall distribute the net proceeds of the
sale to the Prohibited Transferee (or, in the case of a devise or gift, the
Prohibited Owner).

     These restrictions do not preclude settlement of transactions through the
NYSE.

     Each stockholder shall upon demand be required to disclose to the
Company in writing any information with respect to the direct, indirect and
constructive ownership of capital stock as the Board of Directors deems
necessary to comply with the provisions of the Code applicable to REITs, to
comply with the requirements of any taxing authority or governmental agency or
to determine any such compliance.

     The Ownership Limit may have the effect of precluding acquisition of
control of the Company.


                       FEDERAL INCOME TAX CONSIDERATIONS

     The following is a general summary of the material Federal income tax
considerations associated with an investment in the Common Stock. The following
discussion is not exhaustive of all possible tax considerations and is not tax
advice. Moreover, this summary does not deal with all tax aspects that might be
relevant to a particular prospective stockholder in light of his or her personal
circumstances; nor does it deal with particular types of stockholders that are
subject to special treatment under the Code, such as insurance companies,
financial institutions and broker-dealers. The Code provisions governing the
Federal income tax treatment of REITs are highly technical and complex, and this
summary is qualified in its entirety by the applicable Code provisions, rules
and regulations promulgated thereunder, and administrative and judicial
interpretations thereof. The following discussion is based on current law.
Unless the context requires otherwise, references to the "Company" in this
"Federal Income Tax Considerations" section refer only to Boston Properties,
Inc.

     EACH STOCKHOLDER IS URGED TO CONSULT HIS OR HER OWN TAX ADVISER REGARDING
THE SPECIFIC TAX CONSEQUENCES TO HIM OR HER OF THE PURCHASE, OWNERSHIP AND SALE
OF COMMON STOCK AND OF THE COMPANY'S ELECTION TO BE TAXED AS A REIT, INCLUDING
THE FEDERAL, STATE, LOCAL, FOREIGN AND OTHER TAX CONSEQUENCES OF SUCH PURCHASE,
OWNERSHIP AND SALE.

                            OPINION OF TAX COUNSEL

     In the opinion of Goodwin, Procter & Hoar LLP, commencing with the
Company's taxable year ended December 31, 1997, the Company qualified to be
taxed as a REIT under the Code, provided that the Company and the Operating
Partnership operate in accordance with various assumptions and factual
representations made by the Company and the Operating Partnership concerning
their business, properties and operations. It must be emphasized that Goodwin,
Procter & Hoar LLP's opinion is based on various assumptions and is conditioned
upon such assumptions and representations made by the Company and the Operating
Partnership concerning their business and properties. In addition, Goodwin,
Procter & Hoar LLP's opinion is based upon the factual representations of the
Company and the Operating Partnership concerning its business and properties.
Moreover, such qualification and taxation as a REIT depends upon the Company's
ability to meet, through actual annual operating results, distribution levels
and diversity of stock ownership, the various qualification tests imposed under
the Code discussed below, the results of which will not be reviewed by Goodwin,
Procter & Hoar LLP. Accordingly, no assurance can be given that the actual
results of the Company's operations for any one taxable year will satisfy such
requirements. See "Risk Factors--Failure to Qualify as a REIT."

     The opinion of Goodwin, Procter & Hoar LLP is also based upon existing
law as currently applicable, Internal Revenue Service ("IRS") regulations,
currently published administrative positions of the IRS and judicial decisions,
which are subject to change either prospectively or retroactively. No assurance
can be given that any such changes would not modify the conclusions expressed in
the opinion. Moreover, unlike a private letter ruling (which will not be
sought), an opinion of counsel is not binding on the IRS, and no assurance can
be given that the IRS will not successfully challenge the status of the Company
as a REIT.

     If the Company qualifies for taxation as a REIT, it generally will not
be subject to Federal corporate income taxes on that portion of its ordinary
income or capital gain that is currently distributed to stockholders. The REIT
provisions of the Code generally allow a REIT to deduct dividends paid to its
stockholders. This deduction for dividends paid to stockholders substantially
eliminates the federal "double taxation" on earnings (once at the corporate
level and once again at the stockholder level) that usually results from
investments in a corporation.

     Even if the Company qualifies for taxation as a REIT, however, the
Company will be subject to Federal income tax, as follows: First, the Company
will be taxed at regular corporate rates on its undistributed REIT taxable
income, including undistributed net capital gains. Second, under certain
circumstances, the Company may be subject to the "alternative minimum tax."
Third, if the Company has net income from the sale or other disposition of
"foreclosure property" that is held primarily for sale to customers in the
ordinary course of business or other non-qualifying income from foreclosure
property, it will be subject to tax at the highest corporate rate on such
income. Fourth, if the Company has net income from prohibited transactions
(which are, in general, certain sales or other dispositions of property other
than foreclosure property held primarily for sale to customers in the ordinary
course of business), such income will be subject to a 100% tax. Fifth, if the
Company should fail to satisfy either the 75% or 95% gross income test
(discussed below) but has nonetheless maintained its qualification as a REIT
because certain other requirements have been met, it will be subject to a 100%
tax on the net income attributable to the greater of the amount by which the
Company fails the 75% or 95% test, multiplied by a fraction intended to reflect
the Company's profitability. Sixth, if the Company fails to distribute during
each year at least the sum of (i) 85% of its REIT ordinary income for such year,
(ii) 95% of its REIT capital gain net income for such year and (iii) any
undistributed taxable income from prior periods, the Company will be subject to
a 4% excise tax on the excess of such required distribution over the amounts
actually distributed. Seventh, if the Company should acquire any asset from a C
corporation (i.e., a corporation generally subject to full corporate-level tax)
in a carryover-basis transaction and the Company subsequently 

                                       15

 
recognizes gain on the disposition of such asset during the ten-year period (the
"Recognition Period") beginning on the date on which the asset was acquired by
the Company, then, to the extent of the excess of (a) the fair market value of
the asset as of the beginning of the applicable Recognition Period over (b) the
Company's adjusted basis in such asset as of the beginning of such Recognition
Period (the "Built-In Gain"), such gain will be subject to tax at the highest
regular corporate rate, pursuant to guidelines issued by the IRS (the "Built-In
Gain Rules").

                        REQUIREMENTS FOR QUALIFICATION

     The Company elected to be taxable as a REIT for its taxable year ended
December 31, 1997 and in order to have so qualified, it must have met and
continued to meet the requirements, discussed below relating to the Company's
organization, source of income, nature of assets and distributions of income to
stockholders.

ORGANIZATIONAL REQUIREMENTS

     The Code defines a REIT as a corporation, trust or association: (i) that
is managed by one or more directors or trustees, (ii) the beneficial ownership
of which is evidenced by transferable shares or by transferable certificates of
beneficial interest, (iii) that would be taxable as a domestic corporation but
for the REIT requirements, (iv) that is neither a financial institution nor an
insurance company subject to certain provisions of the Code, (v) the beneficial
ownership of which is held by 100 or more persons, and (vi) during the last half
of each taxable year not more than 50% in value of the outstanding stock of
which is owned, directly or indirectly through the application of certain
attribution rules, by five or fewer individuals (as defined in the Code to
include certain entities). In addition, certain other tests, described below,
regarding the nature of its income and assets also must be satisfied. The Code
provides that conditions (i) through (iv), inclusive, must be met during the
entire taxable year and that condition (v) must be met during at least 335 days
of a taxable year of 12 months, or during a proportionate part of a taxable year
of less than 12 months. Conditions (v) and (vi) (the "100 Stockholder
Requirement" and "Five or Fewer Requirement") will not apply until after the
first taxable year for which an election is made to be taxed as a REIT. For
purposes of conditions (v) and (vi), pension funds and certain other tax-exempt
entities are treated as individuals, subject to a "look-through" exception in
the case of condition (vi).

    
     In order to protect the Company from a concentration of ownership of its
stock that would cause the Company to fail the Five or Fewer Requirement, the
Company's Certificate provides that stock owned, or deemed to be owned or
transferred to a stockholder in excess of the Ownership Limit or the
Look-Through Ownership Limit will automatically be converted into Excess Stock
and transferred to a charity for resale, with the original stockholder entitled
to receive certain proceeds from such a resale. See "Description of Capital
Stock--Restrictions on Transfers." Excess Stock is a separate class of capital
stock of the Company that is entitled to no voting rights but shares ratably
with the Common Stock in dividends and rights upon dissolution. Because of the
absence of authority on this issue, however, there is no assurance that the
operation of the Excess Stock or other provisions contained in the Certificate
will, as a matter of law, prevent a concentration of ownership of stock in
excess of the Ownership Limit from causing the Company to violate the Five or
Fewer Requirement. If there were a concentration of ownership that would cause
the Company to violate the Five or Fewer Requirement, and the operation of the
Excess Stock or other provisions contained in the Certificate were not held to
cure such violation, the Company would be disqualified as a REIT. In rendering
its opinion that the Company is organized in a manner that permits the Company
to qualify as a REIT, Goodwin, Procter & Hoar LLP is relying on the
representation of the Company that the ownership of its stock (without regard to
the Excess Stock provisions) satisfies the Five or Fewer Requirement, and
Goodwin, Procter & Hoar LLP expresses no opinion as to whether, as a matter of
law, the Excess Stock or other provisions contained in the Certificate preclude
the Company from failing the Five or Fewer Requirement.       

     In addition, a corporation may not elect to become a REIT unless its
taxable year is the calendar year. The Company's taxable year is the calendar
year.

                                       16

 
     In the case of a REIT that is a partner in a partnership, Treasury
Regulations provide that the REIT will be deemed to own its proportionate share
(based on its interest in partnership capital) of the assets of the partnership
and will be deemed to be entitled to the income of the partnership attributable
to such share. In addition, the character of the assets and gross income of the
partnership shall retain the same character in the hands of the REIT for
purposes of Section 856 of the Code, including satisfying the gross income tests
and asset tests. Thus, the Company's proportionate share of the assets,
liabilities and items of income of the Operating Partnership (including the
Operating Partnership's share of the assets and liabilities and items of income
with respect to any partnership in which it holds an interest) are treated as
assets, liabilities and items of income of the Company for purposes of applying
the requirements described herein.

INCOME TESTS

     To maintain qualification as a REIT, two gross income requirements must
be satisfied annually.

    
     .    First, at least 75% of the Company's gross income, excluding gross
          income from certain disposition, of property held primarily for sale
          to customers in the ordinary course of a trade or business
          ("prohibited transactions"), for each taxable year must be derived
          directly or indirectly from investments relating to real property or
          mortgages on real property (including "rents from real property" and,
          in certain circumstances, interest) or from certain types of temporary
          investments.       

     .    Second, at least 95% of the Company's gross income (excluding gross
          income from prohibited transactions) for each taxable year must be
          derived from such real property investments described above and from
          dividends, interest and gain from the sale or disposition of stock or
          securities or from any combination of the foregoing.

     Rents received or deemed to be received by the Company qualify as "rents
from real property" in satisfying the gross income requirements for a REIT
described above only if several conditions are met.

     .    First, the amount of rent generally must not be based in whole or in
          part on the income or profits of any person. An amount received or
          accrued generally will not be excluded from the term "rents from real
          property," however, solely by reason of being based on a fixed
          percentage or percentages of receipts or sales.

     .    Second, the Code provides that rents received from a tenant will not
          qualify as "rents from real property" in satisfying the gross income
          tests if the REIT, or an owner of 10% or more of the REIT, directly or
          constructively owns 10% or more of such tenant (a "Related Party
          Tenant") or a subtenant of such tenant (in which case only rent
          attributable to the subtenant is disqualified).

     .    Third, if rent attributable to personal property, leased in connection
          with a lease of real property, is greater than 15% of the total rent
          received under the lease, then the portion of rent attributable to the
          personal property will not qualify as "rents from real property."

     .    Finally, for rents to qualify as "rents from real property" the REIT
          must not operate or manage the property or furnish or render services
          to tenants, other than through an "independent contractor" who is
          adequately compensated and from whom the REIT does not derive any
          income; provided, however, that a REIT may provide services with
          respect to its properties and the income will qualify as "rents from
          real property" if the services are "usually or customarily rendered"
          in connection with the rental of room or other space for occupancy
          only and are not otherwise considered "rendered to the occupant," or
          if the services with respect to a property are impermissible tenant
          services the income from such services does not exceed one percent of
          all amounts received or accrued with respect to that property. In
          establishing the amount of impermissible tenant services income, such
          amount must be at least 150 percent of the direct cost of providing
          the tenant services, or managing or operating the property.
        

                                       17

 
     The Company does not charge rent that is based in whole or in part on the
income or profits of any person (except by reason of being based on a fixed
percentage or percentages of receipts or sales consistent with. the rule
described above). The Company does not derive, and does not anticipate deriving,
rent attributable to personal property leased in connection with real property
that exceeds 15% of the total rents.

     Pursuant to leases with respect to two hotel properties, ZL Hotel LLC
leases from the Operating Partnership the two hotel properties for a ten year
period. The hotel leases provide that ZL Hotel LLC is obligated to pay to the
Operating Partnership (i) the greater of Base Rent or Participating Rent
(collectively, the "Rents") and (ii) Additional Charges. Participating Rent is
calculated by multiplying fixed percentages by various revenue categories for
each of the Hotel Properties. Both Base Rent and the thresholds in the
Participating Rent formulas will be adjusted for inflation. Base Rent accrues
and is required to be paid monthly. Participating Rent is payable monthly, with
monthly adjustments based on actual results.

    
     In order for the Rents and Additional Charges to constitute "rents from
real property," the leases must be respected as true leases for federal income
tax purposes and not treated as service contracts, joint ventures or some other
type of arrangement. The determination of whether the leases are true leases
depends on an analysis of all the surrounding facts and circumstances. In making
such a determination, courts have considered a variety of factors, including the
following: (i) the intent of the parties, (ii) the form of the agreement, (iii)
the degree of control over the property that is retained by the property owner
(e.g., whether the lessee has substantial control over the operation of the
property or whether the lessee was required simply to use its best efforts to
perform its obligations under the agreement), and (iv) the extent to which the
property owner retains the risk of loss with respect to the property (e.g.,
whether the lessee bears the risk of increases in operating expenses or the risk
of damage to the property) or the potential for economic gain (e.g.,
appreciation ) with respect to the property.       

     In addition, Code section 7701(e) provides that a contract that purports
to be a service contract (or a partnership agreement) is treated instead as a
lease of property if the contract is properly treated as such, taking into
account all relevant factors, including whether or not: (i) the service
recipient is in physical possession of the property, (ii) the service recipient
controls the property, (iii) the service recipient has a significant economic or
possessory interest in the property (e.g., the property's use is likely to be
dedicated to the service recipient for a substantial portion of the useful life
of the property, the recipient shares the risk that the property will decline in
value, the recipient shares in any appreciation in the value of the property,
the recipient shares in savings in the property's operating costs, or the
recipient bears the risk of damage to or loss of the property), (iv) the service
provider does not bear any risk of substantially diminished receipts or
substantially increased expenditures if there is nonperformance under the
contract, (v) the service provider does not use the property concurrently to
provide significant services to entities unrelated to the service recipient, and
(vi) the total contract price does not substantially exceed the rental value of
the property for the contract period. Since the determination whether a service
contract should be treated as a lease is inherently factual, the presence or
absence of any single factor may not be dispositive in every case. The hotel
leases were structured to qualify as true leases for Federal income tax
purposes.

    
     Investors should be aware that there are no controlling Treasury
Regulations, published rulings, or judicial decisions involving leases with
terms substantially the same as the hotel leases that discuss whether such
leases constitute true leases for Federal income tax purposes. Therefore, there
can be no complete assurance that the IRS will not assert a contrary position.
If the leases are recharacterized as service contracts or partnership
agreements, rather than true leases, part or all of the payments that the
Operating Partnership receives from the lessee would not be considered rent or
would not otherwise satisfy the various requirements for qualification as rents
from real property." In that case, the Company likely would not be able to
satisfy either the 75% or 95% gross income tests and, as a result, would lose
its REIT status.       

     As indicated above, "rents from real property" must not be based in whole
or in part on the income or profits of any person. The Participating Rent should
qualify as "rents from real property" since it is based on percentages of
receipts or sales which percentages are fixed at the time the leases are entered
into, provided (i) the leases are not renegotiated during the term of the leases
in a manner that has the effect of basing

                                       18

 
Participating Rent on income or profits and (ii) the leases conform with normal
business practice. More generally, the Participating Rent will not qualify as
"rents from real property" if, considering the hotel leases and all the
surrounding circumstances, the arrangement does not conform with normal business
practice, but is in reality used as a means of basing the Participating Rent on
income or profits. Since the Participating Rent is based on fixed percentages of
the gross revenues from the hotels that are established in the hotel leases, and
the Company has represented that the percentages (i) will not be renegotiated
during the terms of the leases in a manner that has the effect of basing the
Participating Rent on income or profits and (ii) conform with normal business
practice, the Participating Rent should not be considered based in whole or in
part on the income or profits of any person. Furthermore, the Company has
represented that, with respect to other hotel properties that it acquires in the
future, it will not charge rent for any property that is based in whole or in
part on the income or profits of any person (except by reason of being based on
a fixed percentage of gross revenues, as described above.)

    
     Pursuant to leases with independent third parties, the Operating
Partnership or certain subsidiary partnerships leases garage property and the
garage portions of certain office properties to independent third parties for
periods between one to three years. The parking leases provide that the
Operating Partnership will receive rent based on the gross receipts of the
parking garage. The same "true lease" and "rent from real property" analysis
applies with respect to the parking leases as is described above for the hotel
leases. The garage leases also have been structured to qualify as true leases
for Federal income tax purposes. As is the case with respect to the hotel
leases, there can be no complete assurance that the IRS will not assert a
contrary position, which if successful could result in the loss of the Company's
status as a REIT.       

     Through the Operating Partnership, which is not an "independent
contractor," the Company provides certain services with respect to the
Properties, but the Company believes (and has represented to Goodwin, Procter &
Hoar LLP) that all such services are considered "usually or customarily
rendered" in connection with the rental of space for occupancy only, so that the
provision of such services does not jeopardize the qualification of rent from
the Properties as "rents from real property." In rendering its opinion on the
Company's ability to qualify as a REIT, Goodwin, Procter & Hoar LLP is relying
on such representations. In the case of any services that are not" usual and
customary" under the foregoing rules, the Company intends to employ "independent
contractors" to provide such services.

     The Operating Partnership may receive certain types of income with respect
to the properties it owns that will not qualify under the 75% or 95% gross
income test. The Company believes, however, that the aggregate amount of such
non-qualifying income in any taxable year will not cause the Company to exceed
the limits on non-qualifying income under the 75% and 95% gross income tests.

     If the Company fails to satisfy one or both of the 75% or 95% gross income
tests for any taxable year, it may nevertheless qualify as a REIT for that year
if it is eligible for relief under certain provisions of the Code. These relief
provisions generally will be available if (i) the Company's failure to meet
these tests was due to reasonable cause and not due to willful neglect, (ii) the
Company attaches a schedule of the sources of its income to its Federal income
tax return and (iii) any incorrect information on the schedule is not due to
fraud with intent to evade tax. It is not possible, however, to state whether,
in all circumstances, the Company would be entitled to the benefit of these
relief provisions. For example, if the Company fails to satisfy the gross income
tests because nonqualifying income that the Company intentionally incurs exceeds
the limits on such income, the IRS could conclude that the Company's failure to
satisfy the tests was not due to reasonable cause. As discussed above in
"Opinion of Tax Counsel," even if these relief provisions apply, a tax would be
imposed with respect to the excess net income. For taxable years prior to
January 1, 1998, a REIT had to satisfy an additional gross income test annually-
less than 30% of the Company's gross income could consist of short-term gain
from the sale or other disposition of stock or securities, gain from prohibited
transactions and gain from the sale or other disposition of real property held
for less than four years. No mitigation provision was applicable if the company
were to fail to satisfy the 30% income test for its taxable year ended December
31, 1997. See "Risk Factors-- Failure to Qualify as a REIT."

                                       19

 
ASSET TESTS

     At the close of each quarter of its taxable year, the Company also must
satisfy three tests relating to the nature and diversification of its assets.

     .    First, at least 75% of the value of the Company's total assets must be
          represented by real estate assets, cash, cash items and government
          securities.

     .    Second, no more than 25% of the Company's total assets may be
          represented by securities other than those in the 75% asset class.

     .    Third, of the investments included in the 25% asset class, the value
          of any one issuer's securities owned by the Company may not exceed 5%
          of the value of the Company's total assets, and the Company may not
          own more than 10% of any one issuer's outstanding voting securities.

     The 5% test must generally be met for any quarter in which the Company
acquires securities of an issuer. After initially meeting the asset tests at the
close of any quarter, the Company will not lose its status as a REIT for failure
to satisfy the asset tests at the end of a later quarter solely by reason of
changes in asset values. If the failure to satisfy the asset tests results from
an acquisition of securities or other property during a quarter, the failure can
be cured by disposition of sufficient nonqualifying assets within 30 days after
the close of that quarter. The Company maintains, and will continue to maintain,
adequate records of the value of its assets to ensure compliance with the asset
tests and will take such other actions within 30 days after the close of any
quarter as may be required to cure any noncompliance.

ANNUAL DISTRIBUTION REQUIREMENTS

    
     In order to be taxed as a REIT, the Company is required to distribute
dividends (other than capital gain dividends) to its stockholders in an amount
at least equal to (a) the sum of (i) 95% of the Company's "REIT taxable income"
(computed without regard to the dividends-paid deduction and the Company's
capital gain) and (ii) 95% of the net income, if any, from foreclosure property
in excess of the special tax on income from foreclosure property, minus (b) the
sum of certain items of cash income. Such distributions must be paid in the
taxable year to which they relate, or in the following taxable year if declared
before the Company timely files its Federal income tax return for such year and
if paid on or before the first regular dividend payment after such declaration.
Even if the Company satisfies the foregoing distribution requirements, to the
extent that the Company does not distribute all of its net capital gain or "REIT
taxable income" as adjusted, it will be subject to tax thereon at regular
capital gains or ordinary corporate tax rates. Furthermore, if the Company
should fail to distribute during each calendar year at least the sum of (a) 85%
of its ordinary income for that year, (b) 95% of its capital gain net income
other than such capital gain net income which the REIT elects to retain and pay
tax on for that year and (c) any undistributed taxable income from prior
periods, the Company would be subject to a 4% excise tax on the excess of such
required distribution over the amounts actually distributed. Pursuant to
recently enacted legislation, the Company may elect to retain, rather than
distribute its net long-term capital gains for tax years beginning after August
5, 1997. The effect of such an election is that (i) the Company is required to
pay the tax on such gains, (ii) U.S. Stockholders (as defined below), while
required to include their proportionate share of the undistributed long-term
capital gains in income, will receive a credit or refund for their share of the
tax paid by the REIT and (iii) the basis of U.S. Stockholder's Common Stock
would be increased by the amount of the undistributed long-term capital gains
(minus the amount of capital gains tax paid by the Company) included in the U.S.
Stockholder's long-term capital gains. In addition, if the Company disposes of
any asset subject to the Built-in Gain Rules during the applicable Recognition
Period, the Company will be required, pursuant to guidance issued by the IRS, to
distribute at least 95% of the Built-In Gain (after tax), if any, recognized on
the disposition of the asset.       

     The Company believes it has made and intends to continue to make timely
distributions sufficient to satisfy the annual distribution requirements. In
this regard, the Operating Partnership Agreement authorizes 

                                       20

 
the Company, as general partner, to take such steps as may be necessary to cause
the Operating Partnership to distribute to its partners an amount sufficient to
permit the Company to meet these distribution requirements.

     It is expected that the Company's REIT taxable income will be less than its
cash flow due to the allowance of depreciation and other non-cash charges in
computing REIT taxable income. Accordingly, the Company anticipates that it will
generally have sufficient cash or liquid assets to enable it to satisfy the 95%
distribution requirement. It is possible, however, that the Company, from time
to time, may not have sufficient cash or other liquid assets to meet the 95%
distribution requirement or to distribute such greater amount as may be
necessary to avoid income and excise taxation, as a result of timing differences
between (i) the actual receipt of income and actual payment of deductible
expenses and (ii) the inclusion of such income and deduction of such expenses in
arriving at taxable income of the Company, or as a result of nondeductible
expenses such as principal amortization or capital expenditures in excess of
noncash deductions. In the event that such timing differences occur, the Company
may find it necessary to arrange for borrowings or, if possible, pay taxable
stock dividends in order to meet the dividend requirement.

     Under certain circumstances, the Company may be able to rectify a failure
to meet the distribution requirement for a year by paying "deficiency dividends"
to stockholders in a later year, which may be included in the Company's
deduction for dividends paid for the earlier year. Thus, the Company may be able
to avoid being taxed on amounts distributed as deficiency dividends. The Company
will, however, be required to pay interest based upon the amount of any
deduction taken for deficiency dividends.

                              FAILURE TO QUALIFY

     If the Company fails to qualify for taxation as a REIT in any taxable year
and the relief provisions do not apply, the Company will be subject to tax
(including any applicable alternative minimum tax) on its taxable income at
regular corporate rates. Distributions to stockholders in any year in which the
Company fails to qualify will not be deductible by the Company nor will they be
required to be made. In such event, to the extent of current or accumulated
earnings and profits, all distributions to stockholders will be dividends,
taxable as ordinary income, and subject to certain limitations of the Code,
corporate distributes may be eligible for the dividends-received deduction.
Unless the Company is entitled to relief under specific statutory provisions,
the Company also will be disqualified from taxation as a REIT for the four
taxable years following the year during which qualification was lost. It is not
possible to state whether in all circumstances the Company would be entitled to
such statutory relief. For example, if the Company fails to satisfy the gross
income tests because nonqualifying income that the Company intentionally incurs
exceeds the limit on such income, the IRS could conclude that the Company's
failure to satisfy the tests was not due to reasonable cause. See "Risk Factors-
Failure to Qualify as a REIT would cause the Company to be Taxed as a
Corporation--Other Tax Liabilities."

                         TAXATION OF U.S. STOCKHOLDERS

    
     As used herein, the term "U.S. Stockholder" means a holder of Common Stock
and Preferred Stock that for United States Federal income tax purposes (a) is a
citizen or resident of the United States, (b) is a corporation, partnership or
other entity created or organized in or under the laws of the United States or
of any political subdivision thereof, (c) is an estate or trust, the income of
which is subject to United States Federal income taxation regardless of its
source or (d) a trust if a United States court is able to exercise primary
supervision over the administration of such trust and one or more United States
persons have the authority to control all substantial decisions of such trust.
For any taxable year for which the Company qualifies for taxation as a REIT,
amounts distributed to taxable U.S. Stockholders will be taxed as follows.      

DISTRIBUTIONS GENERALLY

     Distributions to U.S. Stockholders, other than capital gain dividends
discussed below, will constitute dividends up to the amount of the Company's
current or accumulated earnings and profits and will be taxable to the
stockholders as ordinary income. These distributions are not eligible for the
dividends-received deduction 

                                       21

 
for corporations. To the extent that the Company makes a distribution in excess
of its current or accumulated earnings and profits, the distribution will be
treated first as a tax-free return of capital, reducing the tax basis in the
U.S. Stockholder's Common Stock, and the amount of such distribution in excess
of a U.S. Stockholder's tax basis in its Common Stock will be taxable as gain
realized from the sale of its Common Stock. Dividends declared by the Company in
October, November or December of any year payable to a stockholder of record on
a specified date in any such month shall be treated as both paid by the Company
and received by the stockholder on December 31 of the year, provided that the
dividend is actually paid by the Company during January of the following
calendar year. Stockholders may not include on their own Federal income tax
returns any losses of the Company.

     The Company will be treated as having sufficient earnings and profits to
treat as a dividend any distribution by the Company up to the amount required to
be distributed in order to avoid imposition of the 4% excise tax discussed in
"Opinion of Tax Counsel" above. Moreover, any "deficiency dividend" will be
treated as an ordinary or capital gain dividend, as the case may be, regardless
of the Company's earnings and profits. As a result, stockholders may be required
to treat certain distributions that would otherwise result in a tax-free return
of capital as taxable dividends.

CAPITAL GAIN DIVIDENDS

     Dividends to U.S. Stockholders that are properly designated by the Company
as capital gain dividends will be treated as long-term capital gains (to the
extent they do not exceed the Company's actual net capital gain) for the taxable
year without regard to the period for which the stockholder has held his stock.

PASSIVE ACTIVITY LOSS AND INVESTMENT INTEREST LIMITATIONS

     Distributions from the Company and gain from the disposition of shares of
Common Stock will not be treated as passive activity income, and therefore
stockholders may not be able to apply any "passive losses" against such income.
Dividends from the Company (to the extent they do not constitute a return of
capital) will generally be treated as investment income for purposes of the
investment income limitation. Net capital gain from the disposition of shares of
Common Stock and capital gain dividends generally will be included in investment
income for purposes of the investment interest deduction limitations only if and
to the extent the stockholder so elects, in which case such capital gains will
be taxed as ordinary income.

CERTAIN DISPOSITIONS OF COMMON STOCK

     Losses incurred on the sale or exchange of shares of Common Stock held for
less than six months (after applying certain holding period rules) will be
deemed capital loss to the extent of any capital gain dividends received by the
selling stockholder from those shares.

TREATMENT OF TAX-EXEMPT STOCKHOLDERS

     Distributions from the Company to a tax-exempt employee pension trust or
other domestic tax-exempt stockholder generally, will not constitute "unrelated
business taxable income" ("UBTI") unless the stockholder has borrowed to acquire
or carry its Common Stock. Qualified trusts that hold more than 10% (by value)
of the shares of certain REITs, however, may be required to treat a certain
percentage of such a REIT's distributions as UBTI. This requirement will apply
only if (i) the REIT would not qualify as such for Federal income tax purposes
but for the application of the "look-through" exception to the Five or Fewer
Requirement applicable to shares held by qualified trusts and (ii) the REIT is
"predominantly held" by qualified trusts. A REIT is predominantly held by
qualified trusts if either (i) a single qualified trust holds more than 25% by
value of the interests in the REIT or (ii) one or more qualified trusts, each
owning, more than 10% by value of the interests in the REIT, hold in the
aggregate more than 50% of the interests in the REIT. The percentage of any REIT
dividend treated as UBTI is equal to the ratio of (a) the UBTI earned by the
REIT (treating the REIT as if it were a qualified trust and therefore subject to
tax on UBTI) to (b) the total gross income (less certain associated expenses) of
the REIT. A de minimis exception applies where the ratio set forth in the
preceding 

                                       22

 
sentence is less than 5% for any year. For these purposes, a qualified
trust is any trust described in section 401(a) of the Code and exempt from tax
under section 501 (a) of the Code. The provisions requiring qualified trusts to
treat a portion of REIT distributions as UBTI will not apply if the REIT is able
to satisfy the Five or Fewer Requirement without relying upon the "look-through"
exception.


              SPECIAL TAX CONSIDERATIONS FOR FOREIGN STOCKHOLDERS

        The rules governing United States income taxation of non-resident alien
individuals, foreign corporations, foreign partnerships and foreign trusts and
estates (collectively, "Non-U.S. Stockholders") are complex, and the following
discussion is intended only as a summary of these rules. Prospective Non-U.S.
Stockholders should consult with their own tax advisors to determine the impact
of federal, state and local income tax laws on an investment in the Company,
including any reporting requirements.

    
        In general, Non-U.S. Stockholders will be subject to regular United
States Federal income tax with respect to their investment in the Company if the
investment is "effectively connected" with the Non-U.S. Stockholder's conduct of
a trade or business in the United States. A corporate Non-U.S. Stockholder that
receives income that is (or is treated as) effectively connected with a 
United States trade or business also may be subject to the branch profits tax
under section 884 of the Code, which is payable in addition to regular United
States Federal corporate income tax. The following discussion will apply to 
Non-U.S. Stockholders whose investment in the Company is not so effectively
connected.       

        A distribution by the Company that is not attributable to gain from the
sale or exchange by the Company of a United States real property interest and
that is not designated by the Company as a capital gain dividend will be treated
as an ordinary income dividend to the extent that it is made out of current or
accumulated earnings and profits. Generally, any ordinary income dividend will
be subject to a United States federal income tax equal to 30% of the gross
amount of the dividend unless this tax is reduced by an applicable tax treaty.
Such a distribution in excess of the Company's earnings and profits will be
treated first as a return of capital that will reduce a Non-U.S. Stockholder's
basis in its Common Stock (but not below zero) and then as gain from the
disposition of such shares, the tax treatment of which is described under the
rules discussed below with respect to dispositions of Common Stock.

        Distributions by the Company that are attributable to gain from the sale
or exchange of a United States real property interest will be taxed to a
Non-U.S. Stockholder under the Foreign Investment in Real Property Tax Act of
1980 ("FIRPTA"). Under FIRPTA, such distributions are taxed to a Non-U.S.
Stockholder as if the distributions were gains "effectively connected" with a
United States trade or business. Accordingly, a Non-U.S. Stockholder will be
taxed at the normal capital gain rates applicable to a U.S. Stockholder (subject
to any applicable alternative minimum tax and a special alternative minimum tax
in the case of non-resident alien individuals). Distributions subject to FIRPTA
also may be subject to a 30% branch profits tax when made to a foreign corporate
stockholder that is not entitled to treaty exemptions.

        Although tax treaties may reduce the Company's withholding obligations,
the Company generally will be required to withhold from distributions to
Non-U.S. Stockholders, and remit to the IRS, (i) 35% of designated capital gain
dividends (or, if greater, 35% of the amount of any distributions that could be
designated as capital gain dividends) and (ii) 30% of ordinary dividends paid
out of earnings and profits. In addition, if the Company designates prior
distributions as capital gain dividends, subsequent distributions, up to the
amount of such prior distributions, will be treated as capital gain dividends
for purposes of withholding. A distribution in excess of the Company's earnings
and profits will be subject to 30% dividend withholding if at the time of the
distribution it cannot be determined whether the distribution will be in an
amount in excess of the Company's current or accumulated earnings and profits.
If the amount of tax withheld by the Company with respect to a distribution to a
Non-U.S. Stockholder exceeds the stockholder's United States tax liability with
respect to such distribution, the Non-U.S. Stockholder may file for a refund of
such excess from the IRS.

                                       23

 
        Unless the Common Stock constitutes a "United States real property
interest" within the meaning of FIRPTA, a sale of Common Stock by a Non-U.S.
Stockholder generally will not be subject to United States federal income
taxation. The Common Stock will not constitute a United States real property
interest if the Company is a "domestically controlled REIT." A domestically
controlled REIT is a REIT in which at all times during a specified testing
period less than 50% in value of its shares is held directly or indirectly by
Non-U.S. Stockholders. It is currently anticipated that the Company will be a
domestically controlled REIT and therefore that sales of Common Stock will not
be subject to taxation under FIRPTA. However, because the Common Stock will be
publicly traded, no assurance can be given that the Company will continue to be
a domestically controlled REIT. If the Company were not a domestically
controlled REIT, whether a Non-U.S. Stockholder's sale of Common Stock would be
subject to tax under FIRPTA as a sale of a United States real property interest
would depend on whether the Common Stock were "regularly traded" on an
established securities market (such as the NYSE on which the Common Stock will
be listed) and on the size of the selling stockholder's interest in the Company.
If the gain on the sale of Common Stock were subject to taxation under FIRPTA,
the Non-U.S. Stockholder would be subject to the same treatment as a U.S.
Stockholder with respect to the gain (subject to any applicable alternative
minimum tax and a special alternative minimum tax in the case of non-resident
alien individuals). In addition, distributions that are treated as gain from the
disposition of Common Stock and are subject to tax under FIRPTA also may be
subject to a 30% branch profit tax when made to a foreign corporate stockholder
that is not entitled to treaty exemptions. In any event, a purchaser of Common
Stock from a Non-U.S. Stockholder will not be required to withhold under FIRPTA
on the purchase price if the purchased Common Stock is "regularly traded" on an
established securities market (such as the NYSE) or if the Company is a
domestically controlled REIT. Otherwise, under FIRPTA the purchaser of Common
Stock may be required to withhold 10% of the purchase price and remit this
amount to the IRS. Capital gains not subject to FIRPTA will be taxable to a
Non-U.S. Stockholder if the Non-U.S. Stockholder is a non-resident alien
individual who is present in the United States for 183 days or more during the
taxable year and certain other conditions apply, in which case the non-resident
alien individual will be subject to a 30% tax on his or her U.S. source capital
gains.

        On October 6, 1997, the U.S. Treasury Department issued final Treasury
regulations governing information reporting and the certification procedures
regarding withholding and backup withholding on certain amounts paid to Non-U.S.
Stockholders after December 31, 1998. The new Treasury regulations may alter the
procedures for claiming the benefits of an income tax treaty. Non-U.S.
Stockholders should consult their tax advisors concerning the effect, if any, of
such new Treasury regulations on an investment in Common Stock.

         INFORMATION REPORTING REQUIREMENTS AND BACKUP WITHHOLDING TAX

        Under certain circumstances, U.S. Stockholders may be subject to backup
withholding at a rate of 31% on payments made with respect to, or cash proceeds
of a sale or exchange of, Common Stock. Backup withholding will apply only if
the holder (i) fails to furnish his or her taxpayer identification number
("TIN") (which, for an individual, would be his or her Social Security Number),
(ii) furnishes an incorrect TIN, (iii) is notified by the IRS that he or she has
failed properly to report payments of interest and dividends or is otherwise
subject to backup withholding or (iv) under certain circumstances, fails to
certify, under penalties of perjury, that he or she has furnished a correct TIN
and (a) that he or she has not been notified by the IRS that he or she is
subject to backup withholding for failure to report interest and dividend
payments or (b) that he or she has been notified by the IRS that he or she is no
longer subject to backup withholding. Backup withholding will not apply with
respect to payments made to certain exempt recipients, such as corporations and
tax-exempt organizations.

        U.S. Stockholders should consult their own tax advisors regarding their
qualifications for exemption from backup withholding and the procedure for
obtaining such an exemption. Backup withholding is not an additional tax.
Rather, the amount of any backup withholding with respect to a payment to a U.S.
Stockholder will be allowed as a credit against the U.S. Stockholder's United
States federal income tax liability and may entitle the U.S. Stockholder to a
refund, provided that the required information is furnished to the IRS.

                                       24

 
        Additional issues may arise pertaining to information reporting and
backup withholding for Non-U.S. Stockholders. Non-U.S. Stockholders should
consult their tax advisors with regard to U.S. information reporting and backup
withholding.

                           OTHER TAX CONSIDERATIONS

EFFECT OF TAX STATUS OF OPERATING PARTNERSHIP ON REIT QUALIFICATION

        Substantially all of the Company's investments are through the Operating
Partnership. In addition, the Operating Partnership holds interests in certain
Properties through subsidiary partnerships. The Company's interest in these
partnerships may involve special tax considerations. Such considerations include
(i) the allocations of items of income and expense, which could affect the
computation of taxable income of the Company, (ii) the status of the Operating
Partnership, and other subsidiary partnerships as partnerships (as opposed to
associations taxable as corporations) for federal income tax purposes, and (iii)
the taking of actions by the Operating Partnership and subsidiary partnerships
that could adversely affect the Company's qualifications as a REIT. In the
opinion of Goodwin, Procter & Hoar LLP, based on certain representations of the
Company and its subsidiaries, each of the Operating Partnership, and the other
subsidiary partnerships in which the Operating Partnership has an interest will
be treated for federal income tax purposes as a partnership (and not as an
association taxable as a corporation). If any of the Operating Partnership, or
other subsidiary partnerships in which the Operating Partnership has an interest
were treated as an association taxable as a corporation, the Company would fail
to qualify as a REIT for a number of reasons.

TAX ALLOCATIONS WITH RESPECT TO THE PROPERTIES

        When property is contributed to a partnership in exchange for an
interest in the partnership, the partnership generally takes a carryover basis
in that property for tax purposes equal to the adjusted basis of the
contributing, partner in the property, rather than a basis equal to the fair
market value of the property at the time of contribution. Pursuant to section
704(c) of the Code, income, gain, loss and deduction attributable to such
contributed property must be allocated in a manner such that the contributing
partner is charged with, or benefits from, respectively, the unrealized gain or
unrealized loss associated with the property at the time of the contribution.
The amount of such unrealized gain or unrealized loss is generally equal to the
difference between the fair market value of the contributed property at the time
of contribution and the adjusted tax basis of such property at the time of
contribution (a "Book-Tax Difference"). Such allocations are solely for Federal
income tax purposes and do not affect the book capital accounts or other
economic or legal arrangements among the partners. The Operating Partnership was
formed by way of contributions of appreciated property (including certain of the
Properties). Consequently, the Operating Partnership Agreement requires such
allocations to be made in a manner consistent with section 704(c) of the Code.
Final and temporary Regulations under Section 704(c) of the Code provide
partnerships with a choice of several methods of accounting for Book-Tax
Differences for property contributed to a partnership on or after December 21,
1993, including the retention of the "traditional method" that was available
under prior law or the election of certain alternative methods. Currently, the
Company intends to elect the "traditional method with curative allocations" of
Section 704(c) allocations. Under the traditional method, which is the least
favorable method from the Company's perspective, the carryover basis of
contributed interests in the Properties in the hands of the Operating
Partnership could cause the Company (i) to be allocated lower amounts of
depreciation deductions for tax purposes than would be allocated to the Company
if all Properties were to have a tax basis equal to their fair market value at
the time of the contribution (the "ceiling rule") and (ii) to be allocated
taxable gain in the event of a sale of such contributed interests in the
Properties in excess of the economic or book income allocated to the Company as
a result of such sale, with a corresponding benefit to the other partners in the
Operating Partnership. If the "traditional method with curative allocations" is
elected by the Company the Operating Partnership Agreement may specially
allocate taxable gain on sale of the Properties to the contributing partners up
to the aggregate amount of depreciation deductions with respect to each such
Property that the "ceiling rule" prevented the Company from being allocated.

                                       25

 
        Interests in the Properties purchased for cash by the Operating
Partnership simultaneously with or subsequent to the admission of the Company to
the Operating Partnership initially had a tax basis equal to their fair market
value. Thus, Section 704(c) of the Code does not apply to such interests.


                              STATE AND LOCAL TAX

        The Company and its operating subsidiaries may be subject to state and
local tax in states and localities in which they do business or own property.
The tax treatment of the Company and its operating subsidiaries and the holders
of Common Stock in such jurisdictions may differ from the Federal income tax
treatment described above.

        In addition, the Taxpayer Relief Act of 1997 includes several
provisions, some of which have been indicated in the discussion above, that will
liberalize certain of the requirements for qualification as a REIT. However,
these provisions will have neither a material beneficial effect nor a material
adverse effect on the Company's ability to operate as a REIT.


                             SELLING STOCKHOLDERS

        As used herein, the term "Selling Stockholders" means (i) the
stockholder listed below who currently holds the Shares set forth opposite its
name and (ii) the unitholder listed below who may, at the Company's option,
receive Shares if such person exercises its right to require the redemption of
the Units set forth opposite its name and the Company elects to acquire such
Units for an equivalent number of Shares.

        The following table provides the names of and the number of shares of
Common Stock and Units owned by each Selling Stockholder, to the best knowledge
of the Company as of August 17, 1998. The Shares offered by this Prospectus may
be offered from time to time by the Selling Stockholders. Since the Company is
not required to issue Shares upon the presentation for redemption of Units and
the Selling Stockholders may sell all, some or none of the Shares, no estimate
can be made of the aggregate number of Shares that will be offered hereby or the
number or percentage of shares of Common Stock that each Selling Stockholder
will own upon completion of the offering to which this Prospectus relates. If
any are sold, each Selling Stockholder will receive all of the net proceeds from
the sale of such stockholder's respective shares of Common Stock offered hereby.

- ---------------- (1) The Prudential Investment Company ("PIC"), a wholly-owned subsidiary of The Prudential Insurance Company of America ("Prudential"), is the investment advisor of Strategic Value Investors II, LLC ("SVI II") pursuant to an Investment Advisory Agreement dated as of June 3, 1998, between PIC and SVI II (the "SVI II Advisory Agreement"). By virtue of the SVI II Advisory Agreement, Prudential, through its wholly-owned subsidiary PIC, has the sole ability to vote and dispose of the 1,675,846 shares of Common Stock owned of record by SVI II. (2) All Units listed in this column can be redeemed for cash at the election of the holder, provided that the Company may elect to acquire any Units presented for redemption for an equivalent number of shares of Common Stock. (3) Assumes that all Units held by the Selling Stockholder are acquired by the Company for shares of Common Stock. The total number of shares of Common Stock outstanding used in calculating this percentage assumes that none of the Units held by other persons are acquired by the Company for shares of Common Stock. (4) Assumes that all Units held by the Selling Stockholder are acquired by the Company for shares of Common Stock. The total number of shares of Common Stock and units of limited partnership interest outstanding used in calculating this percentage includes the total number of shares of Common Stock outstanding and the total number of Units outstanding held by persons other than the Company plus all Series One Preferred Units of Limited Partnership in the Operating Partnership on an as converted basis. 26 SVI-II purchased the shares of Common Stock set forth opposite its name for cash pursuant to a Stock Purchase Agreement dated July 2, 1998. Prudential acquired the Units set forth opposite its name in connection with the contribution to the Operating Partnership of certain real estate assets pursuant to a Contribution Agreement dated May 7, 1998. PLAN OF DISTRIBUTION The Company will not receive any of the proceeds from this Offering. The shares of Common Stock offered hereby may be sold from time to time on the NYSE on terms to be determined at the time of such sales. The Selling Stockholders may also make private sales directly or through a broker or brokers. In addition, the Selling Stockholders may offer or sell the Shares in other ways not including market makers or established trading markets, including sales or distributions to constituent members, owners or interest holders in the Selling Stockholders. Alternatively, the Selling Stockholders may from time to time offer shares of Common Stock to or through underwriters, dealers or agents, who may receive consideration in the form of discounts and commissions; such compensation, which may be in excess of ordinary brokerage commissions, may be paid by the Selling Stockholders and/or the purchasers of the shares of Common Stock offered hereby for whom such underwriters, dealers or agents may act. The Selling Stockholders and any dealers or agents that participate in the distribution of the shares of Common Stock offered hereby may be deemed to be "underwriters" as defined in the Securities Act, and any profit on the sale of such shares of Common Stock offered hereby by them and any discounts, commissions or concessions received by any such dealers or agents might be deemed to be underwriting discounts and commissions under the Securities Act. The aggregate proceeds to the Selling Stockholders from sales of the shares of Common Stock by the Selling Stockholders hereby will be the purchase price of such Common Stock less any broker's commissions. To the extent required, the specific shares of Common Stock to be sold, the names of the Selling Stockholders, the respective purchase prices and public offering prices, the names of any such agent, dealer or underwriter, and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement. The shares of Common Stock offered hereby may be sold from time to time in one or more transactions at a fixed offering price, which may be changed, or at varying prices determined at the time of sale or at negotiated prices. The Selling Stockholders may also loan or pledge the shares of Common Stock registered hereunder to a broker-dealer and such broker-dealer may effect sales of the pledged shares pursuant to this prospectus. In order to comply with the securities laws of certain states, if applicable, the shares of Common Stock offered hereby will be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states securities may not be sold unless they have been registered or qualified for sale or an exemption from the registration or qualification requirement is available and complied with. The Company will pay substantially all the expenses incurred by the Selling Stockholders and the Company incident to the Offering, but excluding any underwriting discounts, commissions, and transfer taxes. LEGAL MATTERS Certain legal matters, including the legality of the Common Stock, will be passed upon for the Company by Goodwin, Procter & Hoar LLP. Gilbert G. Menna, the sole shareholder of Gilbert G. Menna, P.C., a partner of Goodwin, Procter & Hoar LLP, serves as an Assistant Secretary of the Company.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS. The Certificate and the Bylaws provide certain limitations on the liability of the Company's directors and officers for monetary damages to the Company. The Certificate and the Bylaws obligate the Company to indemnify its directors and officers, and permit the Company to indemnify its employees and other agents, against certain liabilities incurred in connection with their service in such capacities. These provisions could reduce the legal remedies available to the Company and the stockholders against these individuals. The Certificate limits the liability of the Company's directors and officers to the Company to the fullest extent permitted from time to time by the DGCL. The DGCL permits, but does not require, a corporation to indemnify its directors, officers, employees or agents and expressly provides that the indemnification provided for under the DGCL shall not be deemed exclusive of any indemnification right under any bylaw, vote of stockholders or disinterested directors, or otherwise. The DGCL permits indemnification against expenses and certain other liabilities arising out of legal actions brought or threatened against such persons for their conduct on behalf of the corporation, provided that each such person acted in good faith and in a manner that he reasonably believed was in or not opposed to the corporation's best interests and in the case of a criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The DGCL does not allow indemnification of directors in the case of an action by or in the right of the corporation (including stockholder derivative suits) unless the directors successfully defend the action or indemnification is ordered by the court. The Certificate contains a provision permitted by Delaware law that generally eliminates the personal liability of directors for monetary damages for breaches of their fiduciary duty, including breaches involving negligence or gross negligence in business combinations, unless the director has breached his or her duty of loyalty, failed to act in good faith, engaged in intentional misconduct or a knowing violation of law, paid a dividend or approved a stock repurchase in violation of the DGCL or obtained an improper personal benefit. The provision does not alter a director's liability under the federal securities laws. In addition, this provision does not affect the availability of equitable remedies, such as an injunction or rescission, for breach of fiduciary duty. The Bylaws provide that directors and officers of the Company shall be, and, in the discretion of the Board of Directors, non-officer employees may be, indemnified by the Company to the fullest extent authorized by Delaware law, as it now exists or may in the future be amended, against all expenses and liabilities actually and reasonably incurred in connection with service for or on behalf of the Company. The Bylaws also provide that the right of directors and officers to indemnification shall be a contract right and shall not be exclusive of any other right now possessed or hereafter acquired under any bylaw, agreement, vote of stockholders, or otherwise. The Company has entered into indemnification agreements with each of its directors and executive officers. The indemnification agreements require, among other matters, that the Company indemnify its directors and officers to the fullest extent permitted by law and advance to the directors and officers all related expenses, subject to reimbursement if it is subsequently determined that indemnification is not permitted. Under these agreements, the Company must also indemnify and advance all expenses incurred by directors and officers seeking to enforce their II-1 rights under the indemnification agreements and may cover directors and officers under the Company's directors' and officers' liability insurance. Although the form of indemnification agreement offers substantially the same scope of coverage afforded by law, it provides additional assurance to directors and officers that indemnification will be available because, as a contract, it cannot be modified unilaterally in the future by the Board of Directors or the Company's stockholders to eliminate the rights it provides. It is the position of the Commission that indemnification of directors and officers for liabilities under the Securities Act is against public policy and unenforceable pursuant to Section 14 of the Securities Act.

ITEM 17. UNDERTAKINGS. (a) The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any acts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; and (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; II-2 provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) herein do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the undersigned registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement; (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described under Item 15 above, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the respective registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, such registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue. II-3 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, Boston Properties, Inc. certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Boston, the Commonwealth of Massachusetts, on this 10th day of September, 1998.

Boston Properties, Inc.

Ladies and Gentlemen:

         

Ladies and Gentlemen:

     We have acted as counsel to Boston Properties, Inc., a Delaware corporation
(the "Company") in connection with the preparation of a registration statement
(the "Registration Statement") filed with the Securities and Exchange Commission
on Form S-3, as amended through the date hereof, with respect to the offer and
sale of (i) up to 1,675,846 shares of the Company's common stock by a holder
thereof, and (ii) up to 2,993,414 shares of the Company's common stock by a
prospective holder thereof, if and to the extent that the Company elects to
issue such shares in exchange for 2,993,414 Units upon the tender of such Units
for redemption (the "Offering").  You have requested our opinion on certain
federal income tax matters in connection with the Offering.

     Capitalized terms not defined herein shall have the same meaning as in the
Registration Statement.

     In rendering the following opinions, we have examined the Amended and
Restated Certificate of Incorporation (the "Articles") and Bylaws of the
Company, and such other records, certificates and documents as we have deemed
necessary or appropriate for purposes of rendering the opinion set forth herein
(collectively, the "Documents").  We have reviewed the proposed investment
activities, operations and governance of the Company and its Subsidiaries.  We
have relied upon representations of duly appointed officers of the Company and
the Operating Partnership (including without limitation, representations
contained in a letter dated as of September 10, 1998 (the "Officer's
Certificate")), principally relating to the Company's organization and
operations.  We assume that each such representation is and will be true,
correct and complete and that all representations that speak in the future, or
to the intention, or to the best of the belief and knowledge of any person(s) or
party(ies) are and will be true, correct and complete as if made without such
qualification.  Nothing has come to our attention which would cause us to
believe that any of such representations are untrue, incorrect or incomplete.
We assume that the Company will be operated in accordance with the applicable
laws and the terms and conditions of applicable documents.  We have also
reviewed the Registration Statement, the 



 
Boston Properties, Inc.
September 11, 1998
Page 2 


Amended and Restated Agreement of Limited Partnership of the Operating
Partnership, and such other documents as we have deemed appropriate. In
addition, we have relied upon certain additional facts and assumptions described
below.

     In rendering the opinion set forth herein, we have assumed (i) the
genuineness of all signatures on documents we have examined, (ii) the
authenticity of all documents submitted to us as originals, (iii) the conformity
to the original documents of all documents submitted to us as copies, (iv) the
conformity of final documents to all documents submitted to us as drafts, (v)
the authority and capacity of the individual or individuals who executed any
such documents on behalf of any person, (vi) the accuracy and completeness of
all records made available to us, and (vii) the factual accuracy of all
representations, warranties and other statements made by all parties.  In
addition, we assume that all interests in the Operating Partnership have been
and will be issued in a transaction (or transactions) that are not required to
be registered under the Securities Act of 1933 and that no interest in the
Operating Partnership offered for sale outside the United States would have been
required to be registered under the Securities Act of 1933 if such interest had
been offered for sale within the United States.  We have further assumed that
during its short 1997 taxable year ending December 31, 1997 and subsequent
taxable years, the Company has operated and will operate in such a manner that
has made and will make the representations contained in the Officer's
Certificate true for all such years, and that the Company and its Subsidiaries
will not make any amendments to its organizational documents after the date of
this opinion that would affect the Company's qualification as a real estate
investment trust for any taxable year.  In addition, we have assumed that the
Company will make an election to be taxable as a real estate investment trust
pursuant to the Internal Revenue Code of 1986, as amended (the "Code") with its
properly and timely filed federal income tax return for its taxable year ending
December 1997.  For purposes of our opinion, we have made no independent
investigation of the facts contained in the documents and assumptions set forth
above, the representations set forth in the Officer's Certificate, or the
Registration Statement.  No facts have come to our attention, however, that
would cause us to question the accuracy and completeness of such facts or
documents in a material way.

     The discussion and conclusion set forth below are based upon the Code, the
Income Tax Regulations and Procedure and Administration Regulations promulgated
thereunder and existing administrative and judicial interpretation thereof, all
of which are subject to change.  No assurance can therefore be given that the
federal income tax consequences described below will not be altered in the
future.  Based on the documents and assumptions set forth above, the
representations set forth in the Officer's Certificate and provided that the
Company continues to meet the applicable asset composition, source of income,
shareholder diversification,

distribution, and other requirements of the Code necessary for a corporation to
qualify as a real estate investment trust, we are of the opinion that

     (1) Commencing with the Company's initial taxable year ended December 31,
1997, the Company has been operated and organized in conformity with the
requirements for qualification as a "real estate investment trust" under the
Code, and its method of operation, as described in the Officers Certificate,
will enable it to continue to meet the requirements for qualification as a "real
estate investment trust" under the Code provided that the Company files a proper
election to be taxed as a real estate investment trust with its timely filed
federal income tax return for the taxable year ended December 31, 1997, and

     (2) The information in the Registration Statement under the caption
"Federal Income Tax Considerations" to the extent that it constitutes matters of
law or legal conclusions, have been reviewed by us and is correct in all
material respects, and our opinion set forth in such discussion is confirmed.

     We will not review on a continuing basis the Company's compliance with the
documents or assumptions set forth above, or the representations set forth in
the Officer's Certificate. Accordingly, no assurance can be given that the
actual results of the Company's operations for any given taxable year will
satisfy the requirements for qualification and taxation as a real estate
investment trust under the Code.  The ability of the Company to continue to meet
the requirements for qualification and taxation as a real estate investment
trust will be dependent upon the Company's ability to continue to meet in each
year the applicable asset composition, source of income, shareholder
diversification, distribution, and other requirements of the Code necessary for
a corporation to qualify as a real estate investment trust.  The foregoing
opinions are limited to the federal income tax matters addressed herein, and no
other opinions are rendered with respect to other federal tax matters or to any
issues arising out of the tax laws of any state or locality.  We express no
opinion with respect to the transactions described herein other than those
expressly set forth herein.  You should recognize that our opinion is not
binding on the IRS and that the IRS may disagree with the opinions contained
herein.  Although we believe that our opinion will be sustained if challenged,
there is no guarantee that this will be the case.  Except as specifically
discussed above, the opinion expressed herein is based upon the laws that
currently exist.  Consequently, future changes in the law may cause the federal
income tax treatment of the transactions herein to be materially and adversely
different from that described above.  This opinion may be relied on solely by
you in connection with the Offering.
