     If holders of up to 2,542,163 common Units of limited partnership interest
in AMB Property, L.P. tender their Units for cash redemption, we may instead
elect to exchange the tendered Units on a one-for-one basis for shares of our
common stock, subject to adjustment. This prospectus relates to the possible
issuance of up to 2,542,163 shares of common stock that we may issue from time
to time to the selling stockholders named in this prospectus upon exchange of
their Units and also relates to the possible offer and sale of those shares from
time to time by the selling stockholders. This registration does not necessarily
mean that we will issue any of the shares or that the selling stockholders will
offer or sell any of the shares.
 
     We are filing the registration statement of which this prospectus is a part
pursuant to a contractual obligation. We will not receive any proceeds from the
issuance of the shares of common stock to the selling stockholders or from the
sale of the shares by the selling stockholders but we have agreed to pay certain
registration expenses. We will acquire Units of limited partnership interest in
AMB Property, L.P. in exchange for any shares that we may issue to unit holders
pursuant to this prospectus.
 
     To facilitate maintenance of our qualification as a Real Estate Investment
Trust (a "REIT") for federal income tax purposes, subject to certain exceptions,
we prohibit the ownership, actually or constructively, by any single person of
more than 9.8% (by value or number of shares, whichever is more restrictive) of
the issued and outstanding shares of our common stock and more than 9.8% (by
value or number of shares, whichever is more restrictive) of the issued and
outstanding shares of our Series A Preferred Stock. We will also prohibit,
subject to certain exceptions, the ownership, actually or constructively, of any
shares of our Series B Preferred Stock and any shares of our Series C Preferred
Stock by any single person so that no such person, taking into account all of
our stock so owned by such person, may own in excess of 9.8% of our issued and
outstanding capital stock.
 
     Our common stock is listed on the New York Stock Exchange under the symbol
"AMB." On December 2, 1998, the last reported sales price of our common stock on
the New York Stock Exchange was $21 1/2 per share.

                           FORWARD LOOKING STATEMENTS
 
     Some of the information included and incorporated by reference in this
prospectus contains forward-looking statements, such as those pertaining to our
(including certain of our subsidiaries') capital resources, portfolio
performance and results of operations. Likewise, the pro forma financial
statements and other pro forma information incorporated by reference in this
prospectus also contain forward-looking statements. In addition, all statements
regarding anticipated growth in our funds from operations and anticipated market
conditions, demographics and results of operations are forward-looking
statements. Forward-looking statements involve numerous risks and uncertainties
and you should not rely on them as predictions of future events. There is no
assurance that the events or circumstances reflected in forward-looking
statements will be achieved or will occur. You can identify forward-looking
statements by the use of forward-looking terminology such as "believes,"
"expects," "may," "will," "should," "seeks," "approximately," "intends,"
"plans," "pro forma," "estimates" or "anticipates" or the negative of these
words and phrases or similar words or phrases. You can also identify
forward-looking statements by discussions of strategy, plans or intentions.
Forward-looking statements are necessarily dependent on assumptions, data or
methods that may be incorrect or imprecise and we may not be able to realize
them. The following factors, among others, could cause actual results and future
events to differ materially from those set forth or contemplated in the
forward-looking statements: defaults on or non-renewal of leases by tenants,
increased interest rates and operating costs, our failure to obtain necessary
outside financing, difficulties in identifying properties to acquire and in
effecting acquisitions, our failure to successfully integrate acquired
properties and operations, risks and uncertainties affecting property
development and construction (including construction delays, cost overruns, our
inability to obtain necessary permits and public opposition to these
activities), our failure
 
                                        3
<PAGE>   7
 
to qualify and maintain our status as a REIT under the Internal Revenue Code of
1986, as amended (the "Code"), environmental uncertainties, risks related to
natural disasters, financial market fluctuations, changes in real estate and
zoning laws and increases in real property tax rates. Our success also depends
upon economic trends generally, including interest rates, income tax laws,
governmental regulation, legislation, population changes and certain other
matters discussed below under "Risk Factors." We caution you not to place undue
reliance on forward-looking statements, which reflect our analysis only.

                                  RISK FACTORS
 
     Before you invest in our common stock, you should be aware that purchasing
or owning our common stock involves various risks, including those described
below. You should consider carefully these risk factors together with all of the
other information included in this prospectus before you decide to purchase
shares of our common stock.
 
THE EXCHANGE OF COMMON LIMITED PARTNERSHIP UNITS FOR COMMON STOCK AND THE
REDEMPTION OF COMMON UNITS FOR CASH ARE TAXABLE TRANSACTIONS
 
     The exchange of the common Units held by a limited partner of the Operating
Partnership for shares of our common stock, or a redemption of such units for
cash, will be treated for tax purposes as a sale of the common Units by the
limited partner. A limited partner will recognize gain or loss for income tax
purposes in an amount equal to the difference between the "amount realized" by
the limited partner in the exchange or redemption and the limited partner's
adjusted tax basis in the common Units exchanged or redeemed. Generally, the
amount realized by a limited partner on an exchange or redemption will be the
fair market value of the exchanged shares received in the exchange, or the
amount of cash received in the redemption, plus the amount of the Operating
Partnership's liabilities allocable to the common Units being exchanged or
redeemed. However, in the event that the Company elects to cause the Operating
Partnership to pay a limited partner cash for a portion of his or her common
Units, under certain circumstances, the limited partner may recognize gain only
to the extent the cash received for such common Units, plus the amount of any
reduction of Operating Partnership liabilities allocable to the limited partner,
exceed the limited partner's basis in all of his or her common Units prior to
such payment. The recognition of any loss resulting from an exchange of common
Units for shares of common stock or a redemption of common Units for cash is
subject to a number of limitations set forth in the Code. It is possible that
the amount of gain realized or even the tax liability resulting from the gain
could exceed the value of the shares of common stock received upon the exchange.
In addition, the ability of a limited partner to sell a substantial number of
shares of common stock in order to raise cash to pay tax liabilities associated
with the exchange of Units may be restricted and, as a result of stock price
fluctuations, the price the holder receives for the shares of common stock may
not equal the value of the Units at the time of exchange.
 
AN INVESTMENT IN COMMON STOCK IS DIFFERENT FROM AN INVESTMENT IN LIMITED
PARTNERSHIP UNITS
 
     If a limited partner exchanges his or her common Units for shares of common
stock, he or she will become one of our stockholders rather than a limited
partner in the Operating Partnership. Although the nature of an investment in
our common stock is similar to an investment in limited partnership Units, there
are also differences between ownership of limited partnership Units and
ownership of our common stock. These differences include:
 
     - form of organization;
 
     - permitted investments;
 
     - policies and restrictions;
 
     - management structure;
 
     - compensation and fees;
 
     - investor rights; and
 
     - federal income taxation.
 
See "Redemption/Exchange of Units for Common Stock -- Comparison of Ownership of
Common Units and Common Stock."

GENERAL REAL ESTATE RISKS
 
  There are Factors Outside of Our Control that Affect the Performance and
  Value of Our Properties
 
     Real property investments are subject to varying degrees of risk. The
yields available from equity investments in real estate depend on the amount of
income earned and capital appreciation generated by the related properties as
well as the expenses incurred in connection with the properties. If our
properties do not generate income sufficient to meet operating expenses,
including debt service and capital expenditures, our ability to pay
distributions to holders of our common stock could be adversely affected. Income
from, and the value of, our properties may be adversely affected by the general
economic climate, local conditions such as oversupply of industrial or retail
space or a reduction in demand for industrial or retail space, the
attractiveness of our properties to potential tenants, competition from other
properties, our ability to provide adequate maintenance and insurance and an
increase in operating costs. In addition, revenues from properties and real
estate values are also affected by factors such as the cost of compliance with
regulations, the potential for liability under applicable laws (including
changes in tax laws), interest rate levels and the availability of financing.
Our income would be adversely affected if a significant number of tenants were
unable to pay rent or if we were unable to rent our industrial or retail space
on favorable terms. Certain significant expenditures associated with an
investment in real estate (such as mortgage payments, real estate taxes and
maintenance costs) generally do not decline when circumstances cause a reduction
in income from the property.
 
  We May Be Unable to Renew Leases or Relet Space as Leases Expire
 
     We are subject to the risks that leases may not be renewed, space may not
be relet, or the terms of renewal or reletting (including the cost of required
renovations) may be less favorable than current lease terms. Leases on a total
of approximately 40.0% of the leased square footage of our properties as of
September 30, 1998 will expire on or prior to December 31, 2000, with leases on
15.0% of the leased square footage of our properties as of September 30, 1998
expiring during the 12 months ending September 30, 1999. In addition, numerous
properties compete with our properties in attracting tenants to lease space,
particularly with respect to retail centers. The number of competitive
commercial properties in a particular area could have a material adverse effect
on our ability to lease space in our properties and on the rents that we are
able to charge. Our financial condition, results of operations, cash flow and
ability to pay distributions on, and the market price of, our common stock could
be adversely affected if we are unable to promptly relet or renew the leases for
all or a substantial portion of expiring leases, if the rental rates upon
renewal or reletting is significantly lower than expected, or if our reserves
for these purposes prove inadequate.
 
  Real Estate Investments are Illiquid
 
     Because real estate investments are relatively illiquid, our ability to
vary our portfolio promptly in response to economic or other conditions is
limited. The limitations in the Code and related regulations on a REIT holding
property for sale may affect our ability to sell properties without adversely
affecting distributions to our stockholders. The relative illiquidity of our
holdings, Code prohibitions and related regulations could impede our ability to
respond to adverse changes in the performance of our investments and could
adversely affect our financial condition, results of operations, cash flow and
ability to pay distributions on, and the market price of, our common stock.
 
                                        6
<PAGE>   10
 
  A Significant Number of Our Properties are Located in California
 
     Our properties located in California as of September 30, 1998 represented
approximately 22.4% of the aggregate square footage of our properties as of
September 30, 1998 and approximately 30.1% of our Annualized Base Rent.
Annualized Base Rent means the monthly contractual amount under existing leases
at September 30, 1998, multiplied by 12. This amount excludes expense
reimbursements and rental abatements. Our revenue from, and the value of, our
properties located in California may be affected by a number of factors,
including local real estate conditions (such as oversupply of or reduced demand
for commercial properties) and the local economic climate. Business layoffs,
downsizing, industry slowdowns, changing demographics and other factors may
adversely impact the local economic climate. A downturn in either the California
economy or in California real estate conditions could adversely affect our
financial condition, results of operations, cash flow and ability to pay
distributions on, and the market price of, our common stock. Certain of our
properties are also subject to possible loss from seismic activity.
 
  Our Properties are Concentrated in the Industrial and Retail Sectors
 
     Our properties are, and are likely to continue to be, concentrated
predominantly in the industrial and retail commercial real estate sectors. This
concentration may expose us to the risk of economic downturns in these sectors
to a greater extent than if our portfolio also included other property types. As
a result, economic downturns in these sectors could have an adverse effect on
our financial condition, results of operations, cash flow and ability to pay
distributions on, and the market price of, our common stock.
 
  Some Potential Losses are Not Covered by Insurance
 
     We carry comprehensive liability, fire, extended coverage and rental loss
insurance covering all of our properties, with policy specifications and insured
limits which we believe are adequate and appropriate under the circumstances
given relative risk of loss, the cost of such coverage and industry practice.
There are, however, certain losses that are not generally insured because it is
not economically feasible to insure against them, including losses due to riots
or acts of war. Certain losses such as losses due to floods or seismic activity
may be insured subject to certain limitations including large deductibles or co-
payments and policy limits. If an uninsured loss or a loss in excess of insured
limits occurs with respect to one or more of our properties, we could lose the
capital we invested in the properties, as well as the anticipated future revenue
from the properties and, in the case of debt which is with recourse to us, we
would remain obligated for any mortgage debt or other financial obligations
related to the properties. Moreover, as the general partner of the Operating
Partnership, we will generally be liable for all of the Operating Partnership's
unsatisfied obligations other than non-recourse obligations. Any such liability
could adversely affect our financial condition, results of operations, cash flow
and ability to pay distributions on, and the market price of, our common stock.
 
     A number of our properties are located in areas that are known to be
subject to earthquake activity, including California where, as of September 30,
1998, 148 industrial buildings aggregating 11.6 million rentable square feet
(representing 19.3% of our properties based on aggregate square footage) and 11
retail centers aggregating 1.8 million rentable square feet (representing 3.1%
of our properties based on aggregate square footage) are located. We carry
replacement cost earthquake insurance on all of our properties located in areas
historically subject to seismic activity, subject to coverage limitations and
deductibles which we believe are commercially reasonable. This insurance
 
                                        7
<PAGE>   11
 
coverage also applies to the properties managed by AMB Investment Management,
Inc. ("AMB Investment Management"), with a single aggregate policy limit and
deductible applicable to those properties and our properties. The Operating
Partnership owns 100% of the non-voting preferred stock of AMB Investment
Management. See "The Preferred Stock Subsidiaries." Through an annual analysis
prepared by outside consultants, we evaluate our earthquake insurance coverage
in light of current industry practice and determine the appropriate amount of
earthquake insurance to carry. We may incur material losses in excess of
insurance proceeds and we may not be able to continue to obtain insurance at
commercially reasonable rates.
 
 We are Subject to Risks and Liabilities In Connection With Properties Owned
 Through Joint Ventures, Limited Liability Companies and Partnerships
 
     We have ownership interests in 19 joint ventures, limited liability
companies or partnerships, including an interest in one unconsolidated entity.
We may make additional investments through these ventures in the future and
presently plan to do so with clients of AMB Investment Management who share
certain approval rights over major decisions. Partnership, limited liability
company or joint venture investments may involve risks such as the following:
 
     - our partners, co-members or joint venturers might become bankrupt (in
       which event we and any other remaining general partners, members or joint
       venturers would generally remain liable for the liabilities of the
       partnership, limited liability company or joint venture);
 
     - our partners, co-members or joint venturers might at any time have
       economic or other business interests or goals which are inconsistent with
       our business interests or goals;
 
     - our partners, co-members or joint venturers may be in a position to take
       action contrary to our instructions, requests, policies or objectives,
       including our policy with respect to maintaining our qualification as a
       REIT; and
 
     - agreements governing joint ventures, limited liability companies and
       partnerships often contain restrictions on the transfer of a joint
       venturer's, member's or partner's interest or "buy-sell" or other
       provisions which may result in a purchase or sale of the interest at a
       disadvantageous time or on disadvantageous terms.
 
We will, however, generally seek to maintain sufficient control of our
partnerships, limited liability companies and joint ventures to permit us to
achieve our business objectives. Our organizational documents do not limit the
amount of available funds that we may invest in partnerships, limited liability
companies or joint ventures. The occurrence of one or more of the events
described above could have an adverse effect on our financial condition, results
of operations, cash flow and ability to pay distributions on, and the market
price of, our common stock.
 
  We may be Unable to Consummate Acquisitions on Advantageous Terms
 
     We intend to continue to acquire industrial and retail properties.
Acquisitions of industrial and retail properties entail risks that investments
will fail to perform in accordance with expectations. Estimates of the costs of
improvements necessary for us to bring an acquired property up to market
standards may prove inaccurate. In addition, there are general investment risks
associated with any new real estate investment. Further, we anticipate
significant competition for attractive investment opportunities from other major
 
                                        8
<PAGE>   12
 
real estate investors with significant capital including both publicly traded
REITs and private institutional investment funds. We expect that future
acquisitions will be financed through a combination of borrowings and proceeds
from equity or debt offerings by us or the Operating Partnership (including
issuances of limited partnership Units), which could have an adverse effect on
our cash flow. We may not be able to acquire additional properties. Our
inability to finance any future acquisitions on favorable terms or the failure
of acquisitions to conform with our expectations or investment criteria could
adversely affect our financial condition, results of operations, cash flow and
ability to pay distributions on, and the market price of, our common stock.
 
 We may be Unable to Complete Renovation and Development on Advantageous Terms
 
     The real estate development business, including the renovation and
rehabilitation of existing properties, involves significant risks. These risks
include the following:
 
     - we may not be able to obtain financing on favorable terms for development
       projects and we may not complete construction on schedule or within
       budget, resulting in increased debt service expense and construction
       costs and delays in leasing such properties and generating cash flow;
 
     - we may not be able to obtain, or we may experience delays in obtaining,
       all necessary zoning, land-use, building, occupancy and other required
       governmental permits and authorizations;
 
     - new or renovated properties may perform below anticipated levels,
       producing cash flow below budgeted amounts;
 
     - substantial renovation as well as new development activities, regardless
       of whether or not they are ultimately successful, typically require a
       substantial portion of management's time and attention which could divert
       management's time from our day-to-day operations; and
 
     - activities that we finance through construction loans involve the risk
       that, upon completion of construction, we may not be able to obtain
       permanent financing or we may not be able to obtain permanent financing
       on advantageous terms.
 
     These risks could have an adverse effect on our financial condition,
results of operations, cash flow and ability to pay distributions on, and the
market price of, our common stock.
 
WE COULD INCUR MORE DEBT
 
     We operate with a policy of incurring debt, either directly or through our
subsidiaries, only if upon such incurrence our debt-to-total market
capitalization ratio would be approximately 45% or less. The aggregate amount of
indebtedness that we may incur under our policy varies directly with the
valuation of our capital stock and the number of shares of capital stock
outstanding. Accordingly, we would be able to incur additional indebtedness
under our policy as a result of increases in the market price per share of our
common stock or other outstanding classes of capital stock, and future issuance
of shares of capital stock. In spite of the foregoing policy, our organizational
documents do not contain any limitation on the amount of indebtedness that we
may incur. Accordingly, our Board of Directors could alter or eliminate this
policy and would do so, for example, if it were necessary for us to continue to
qualify as a REIT. If we change this policy, we could become more highly
leveraged, resulting in an increase in debt service that could adversely
 
                                        9
<PAGE>   13
 
affect our financial condition, results of operations, cash flow and ability to
pay distributions on, and the market price of, our common stock.
 
DEBT FINANCING
 
 Scheduled Debt Payments Could Adversely Affect Our Financial Condition
 
     We are subject to risks normally associated with debt financing, including
the risks that our cash flow will be insufficient to make distributions to our
stockholders, that we will be unable to refinance existing indebtedness on our
properties (which in all cases will not have been fully amortized at maturity)
and that the terms of refinancing will not be as favorable as the terms of
existing indebtedness.
 
     As of September 30, 1998, we had total debt outstanding of approximately
$1.3 billion including:
 
     - approximately $701.6 million of secured indebtedness (including
       unamortized debt premiums of approximately $15.9 million) with an average
       maturity of seven years and a weighted average interest rate of 7.9%;
 
     - approximately $205 million outstanding under our unsecured $500 million
       credit facility (the "Credit Facility") with a maturity date of November
       2000 and a weighted average interest rate of 6.53%; and
 
     - $400 million aggregate principal amount of unsecured senior debt
       securities with maturities in June 2008, 2015 and 2018 and a weighted
       average interest rate of 7.18%.
 
     We are a guarantor of the Operating Partnership's obligations with respect
to the senior debt securities referenced above. If we are unable to refinance or
extend principal payments due at maturity or pay them with proceeds of other
capital transactions, we expect that our cash flow will not be sufficient in all
years to pay distributions to our stockholders and to repay all such maturing
debt. Furthermore, if prevailing interest rates or other factors at the time of
refinancing (such as the reluctance of lenders to make commercial real estate
loans) result in higher interest rates upon refinancing, the interest expense
relating to that refinanced indebtedness would increase. This increased interest
expense would adversely affect our financial condition, results of operations,
cash flow and ability to pay distributions on, and the market price of, our
common stock. In addition, if we mortgage one or more of our properties to
secure payment of indebtedness and we are unable to meet mortgage payments, the
property could be foreclosed upon or transferred to the mortgagee with a
consequent loss of income and asset value. A foreclosure on one or more of our
properties could adversely affect our financial condition, results of
operations, cash flow and ability to pay distributions on, and the market price
of, our common stock.
 
  Rising Interest Rates Could Adversely Affect Our Cash Flow
 
     As of September 30, 1998, we had $205.0 million outstanding under the
Credit Facility. In addition, we may incur other variable rate indebtedness in
the future. Increases in interest rates on this indebtedness could increase our
interest expense, which would adversely affect our financial condition, results
of operations, cash flow and ability to pay distributions on, and the market
price of, our common stock. Accordingly, we may in the future engage in
transactions to limit our exposure to rising interest rates.
 
                                       10
<PAGE>   14
 
  We Are Dependent on External Sources of Capital
 
     In order to qualify as a REIT under the Code, we are required each year to
distribute to our stockholders at least 95% of our REIT taxable income
(determined without regard to the dividends-paid deduction and by excluding any
net capital gain). See "Certain Federal Income Tax Considerations -- Taxation of
the Company -- Annual Distribution Requirements." Because of this distribution
requirement, we may not be able to fund all future capital needs, including
capital needs in connection with acquisitions, from cash retained from
operations. As a result, to fund capital needs, we rely on third-party sources
of capital, which we may not be able to obtain on favorable terms or at all. Our
access to third-party sources of capital depends upon a number of factors,
including general market conditions and the market's perception of our growth
potential and our current and potential future earnings and cash distributions
and the market price of the shares of our capital stock. Additional debt
financing may substantially increase our leverage.
 
  We Could Default on Cross-Collateralized and Cross-Defaulted Debt
 
     As of September 30, 1998, we had 12 non-recourse secured loans which are
cross-collateralized by five pools consisting of 19 properties. As of September
30, 1998, we had $210.2 million outstanding on these loans. If we default on any
of these loans, we will be required to repay the aggregate of all indebtedness,
together with applicable prepayment charges, to avoid foreclosure on all the
cross-collateralized properties within the applicable pool. Foreclosure on our
properties, or our inability to refinance our loans on favorable terms, could
adversely impact our financial condition, results of operations, cash flow and
ability to pay distributions on, and the market price of, our common stock. In
addition, our credit facilities and the senior debt securities of the Operating
Partnership contain certain cross-default provisions which are triggered in the
event that our other material indebtedness is in default. These cross-default
provisions may require us to repay or restructure the credit facilities and the
senior debt securities in addition to any mortgage or other debt which is in
default, which could adversely affect our financial condition, results of
operations, cash flow and ability to pay distributions on, and the market price
of, our common stock.
 
CONTINGENT OR UNKNOWN LIABILITIES COULD ADVERSELY AFFECT OUR FINANCIAL CONDITION
 
     Our predecessors have been in existence for varying lengths of time up to
15 years. At the time of our formation we acquired the assets of these entities
subject to all of their potential existing liabilities. There may be current
liabilities or future liabilities arising from prior activities that we are not
aware of and therefore are not disclosed in this prospectus. We assumed these
liabilities as the surviving entity in the various merger and contribution
transactions that occurred at the time of our formation. Existing liabilities
for indebtedness generally were taken into account (directly or indirectly) in
connection with the allocation of the Units and/or shares of our common stock in
the formation transactions, but no other liabilities were taken into account for
these purposes. We do not have recourse against our predecessors or any of their
respective stockholders or partners or against any individual account investors,
with respect to any unknown liabilities except to the extent
 
                                       11
<PAGE>   15
 
provided by the indemnity escrow agreement entered into in connection with the
formation transactions. Unknown liabilities might include the following:
 
     - liabilities for clean-up or remediation of undisclosed environmental
       conditions;
 
     - claims of tenants, vendors or other persons dealing with our predecessors
       prior to the formation transactions that had not been asserted prior to
       the formation transactions;
 
     - accrued but unpaid liabilities incurred in the ordinary course of
       business;
 
     - tax liabilities; and
 
     - claims for indemnification by the officers and directors of our
       predecessors and others indemnified by these entities.
 
     Certain tenants may claim that the formation transactions gave rise to a
right to purchase the premises that they occupy. We do not believe any such
claims would be material. See "-- Government Regulations -- We Could Encounter
Costly Environmental Problems" below regarding the possibility of undisclosed
environmental conditions potentially affecting the value of our properties.
Undisclosed material liabilities which are not covered by the indemnity escrow
agreement that we entered into with our predecessors in connection with the
formation transactions or undisclosed material liabilities in connection with
the acquisition of properties, entities and interests in properties or entities
could adversely affect our financial condition, results of operations, cash flow
and ability to pay distributions on, and the market price of, our common stock.
 
CONFLICTS OF INTEREST
 
 Some of Our Executive Officers are Involved in Other Real Estate Activities and
 Investments
 
     Some of our executive officers own interests in real estate-related
businesses and investments. These interests include minority ownership of
Institutional Housing Partners, a residential housing finance company, and
ownership of AMB Development, Inc. and AMB Development, L.P., developers which
own property that we believe is not suitable for ownership by us. AMB
Development, Inc. and AMB Development, L.P. have agreed not to initiate any new
development projects following our initial public offering in November, 1997.
These entities have also agreed that they will not make any further investments
in industrial or retail properties other than those currently under development
at the time of our initial public offering. AMB Institutional Housing Partners,
AMB Development, Inc. and AMB Development, L.P. continue to use the name "AMB"
pursuant to royalty-free license arrangements with us. The continued involvement
in other real estate-related activities by some of our executive officers and
directors could divert management's attention from our day-to-day operations.
Most of our executive officers have entered into non-competition agreements with
us pursuant to which they have agreed not to engage in any activities, directly
or indirectly, in respect of commercial real estate, and not to make any
investment in respect of industrial or retail real estate, other than through
ownership of not more than 5% of the outstanding shares of a public company
engaged in such activities or through the existing investments referred to in
this prospectus. State law may limit our ability to enforce these agreements.
 
     We could also, in the future, subject to the unanimous approval of the
disinterested members of the Board of Directors with respect to such
transaction, acquire property from executive officers, enter into leases with
executive officers, and/or engage in other related
 
                                       12
<PAGE>   16
 
activities in which the interests pursued by the executive officers may not be
in the best interests of our stockholders.
 
 Certain of Our Executive Officers and Directors May Have Conflicts of Interest
 with Us in Connection with Other Properties that They Own or Control
 
     AMB Development, L.P. owns interests in 11 retail development projects in
the U.S., each of which consists of a single free-standing Walgreens drugstore,
and, together with other entities controlled by nine of our executive officers,
a low income housing apartment building located in the San Francisco Bay Area.
In addition, Messrs. Abbey, Moghadam and Burke, each a founder and director, own
less than 1% interests in two partnerships which own office buildings in various
markets; these interests have negligible value. Luis A. Belmonte, an executive
officer, owns less than a 10% interest, representing an estimated value of
$75,000, in a limited partnership which owns an office building located in
Oakland, California. David S. Fries, an executive officer, owns an approximate
1% interest in a limited partnership that owns an apartment complex in Orange
County, California.
 
     In addition, several of our executive officers individually own:
 
     - less than 1% interests in the stocks of certain publicly-traded REITs and
       residential developers;
 
     - certain interests in and rights to developed and undeveloped real
       property located outside the United States;
 
     - interests in single-family homes and residential apartments in the San
       Francisco Bay Area;
 
     - certain passive interests, that we do not believe are material, in real
       estate businesses in which such persons were previously employed; and
 
     - certain other de minimis holdings in equity securities of real estate
       companies.
 
     Thomas W. Tusher, a member of our Board of Directors, is a limited partner
in a partnership in which Messrs. Abbey, Moghadam and Burke are general partners
and which owns a 75% interest in an office building. Mr. Tusher owns a 20%
interest in the partnership, valued as of September 30, 1998 at approximately
$1.2 million. Messrs. Abbey, Moghadam and Burke each have an approximately 26.7%
interest in the partnership, each valued as of September 30, 1998 at
approximately $1.6 million.
 
     We believe that the properties and activities set forth above generally do
not directly compete with any of our properties. However, it is possible that a
property in which an executive officer or director, or an affiliate of such
person, has an interest may compete with us in the future if we were to invest
in a property similar in type and in close proximity to that property. In
addition, the continued involvement by our executive officers and directors in
such properties could divert management's attention from our day-to-day
operations. We are prohibited from acquiring any properties from our executive
officers or their affiliates without the approval of the disinterested members
of the Board of Directors with respect to that transaction.
 
 Our Role as General Partner of the Operating Partnership May Conflict with the
 Interests of Our Stockholders
 
     As the general partner of the Operating Partnership, we have fiduciary
obligations to the Operating Partnership's limited partners, the discharge of
which may conflict with the interests of our stockholders. In addition, those
persons holding limited partnership Units
 
                                       13
<PAGE>   17
 
will have the right to vote as a class on certain amendments to the Third
Amended and Restated Agreement of Limited Partnership of the Operating
Partnership (the "Partnership Agreement") and individually to approve certain
amendments that would adversely affect their rights. The limited partners may
exercise these voting rights in a manner that conflicts with the interests of
our stockholders. In addition, under the terms of the Partnership Agreement,
holders of limited partnership Units will have certain approval rights with
respect to certain transactions that affect all stockholders but which they may
not exercise in a manner which reflects the interests of all stockholders. See
"Description of Certain Provisions of the Partnership Agreement of the Operating
Partnership -- Removal of the General Partner; Transferability of our Interests;
Treatment of Units in Significant Transactions."
 
 Our Directors, Executive Officers and Significant Stockholders Could Act in a
 Manner that is Not in the Best Interest of All Stockholders
 
     As of November 30, 1998, our three largest stockholders, Ameritech Pension
Trust, the City and County of San Francisco Employees' Retirement System and
Southern Company System Master Retirement Trust, beneficially owned
approximately 22.9% of our outstanding common stock (assuming the exchange of
all Units into shares of common stock). In addition, our executive officers and
directors beneficially owned 5.9% of our common stock as of the same date
(assuming the exchange of all Units into shares of common stock, before issuance
of any Performance Units to certain of our officers, as defined under the
caption "Description of Certain Provisions of the Partnership Agreement of the
Operating Partnership -- Performance Units"), and will have influence on our
management and operation and, as stockholders, will have influence on the
outcome of any matters submitted to a vote of the stockholders. This influence
might be exercised in a manner that is inconsistent with the interests of other
stockholders. Although there is no understanding or arrangement for these
directors, officers and stockholders and their affiliates to act in concert,
these parties would be in a position to exercise significant influence over our
affairs if they choose to do so.
 
  We Could Suffer Losses if We Fail to Enforce the Terms of Certain Agreements
 
     As holders of shares of our common stock and, potentially, Performance
Units, certain of our directors and officers could have a conflict of interest
with respect to their obligations as directors and officers to vigorously
enforce the terms of certain of the agreements relating to our formation
transactions. The potential failure to enforce the material terms of those
agreements could result in a monetary loss to us, which loss could have a
material adverse effect on our financial condition, results of operations, cash
flow and ability to pay distributions on, and the market price of, our common
stock.
 
OWNERSHIP OF COMMON STOCK
 
  Limitations in Our Charter and Bylaws Could Prevent a Change in Control
 
     Certain provisions of our Charter and Bylaws may delay, defer or prevent a
change in control or other transaction that could provide the holders of our
common stock with the opportunity to realize a premium over the then-prevailing
market price for our common stock. To maintain our qualification as a REIT for
federal income tax purposes, not more than 50% in value of our outstanding stock
may be owned, actually or constructively, by five or fewer individuals (as
defined in the Code to include certain entities) during the last half of a
taxable year after the first taxable year for which a REIT election is made. See
"Certain Federal Income Tax Considerations -- Taxation of the
Company -- Requirements
 
                                       14
<PAGE>   18
 
for Qualification as a REIT." Furthermore, after the first taxable year for
which a REIT election is made, our common stock must be held by a minimum of 100
persons for at least 335 days of a 12-month taxable year (or a proportionate
part of a short tax year). In addition, if we, or an owner of 10% or more of our
stock, actually or constructively owns 10% or more of one of our tenants (or a
tenant of any partnership in which we are a partner), the rent received by us
(either directly or through any such partnership) from that tenant will not be
qualifying income for purposes of the REIT gross income tests of the Code. To
facilitate maintenance of our qualification as a REIT for federal income tax
purposes, we will prohibit the ownership, actually or by virtue of the
constructive ownership provisions of the Code, by any single person of more than
9.8% (by value or number of shares, whichever is more restrictive) of the issued
and outstanding shares of our common stock and more than 9.8% (by value or
number of shares, whichever is more restrictive) of the issued and outstanding
shares of our Series A Preferred Stock, and we will also prohibit the ownership,
actually or constructively, of any shares of our Series B Preferred Stock and
any shares of our Series C Preferred Stock by any single person so that no such
person, taking into account all of our stock so owned by such person, may own in
excess of 9.8% of our issued and outstanding capital stock. We refer to this
limitation as the "ownership limit." Shares acquired or held in violation of the
ownership limit will be transferred to a trust for the benefit of a designated
charitable beneficiary. Any person who acquires shares in violation of the
ownership limit will not be entitled to any distributions on the shares or be
entitled to vote the shares or receive any proceeds from the subsequent sale of
the shares in excess of the lesser of the price paid for the shares or the
amount realized from the sale. A transfer of shares in violation of the above
limits may be void under certain circumstances. See "Description of Capital
Stock -- Restrictions on Ownership and Transfer of Capital Stock." The ownership
limit may have the effect of delaying, deferring or preventing a change in
control and, therefore, could adversely affect our stockholders' ability to
realize a premium over the then-prevailing market price for the shares of our
common stock in connection with such transaction. The Board of Directors has
waived the ownership limit applicable to our common stock with respect to
Ameritech Pension Trust, allowing it to own up to 14.9% of our common stock and,
under some circumstances, allowing it to own up to 19.6%. However, we
conditioned this waiver upon the receipt of undertakings and representations
from Ameritech Pension Trust which we believed were reasonably necessary in
order for us to conclude that the waiver would not cause us to fail to qualify
as a REIT.
 
     Our Charter authorizes us to issue additional shares of common stock and
Series A Preferred Stock and to issue Series B Preferred Stock, Series C
Preferred Stock and one or more other series of preferred stock and to establish
the preferences, rights and other terms of any series of preferred stock that we
issue. See "Description of Capital Stock." Although our Board of Directors has
no intention to do so at the present time, it could establish a series of
preferred stock that could delay, defer or prevent a transaction or a change in
control that might involve a premium price for our common stock or otherwise be
in the best interests of our stockholders.
 
     Our Charter, our Bylaws and Maryland law also contain other provisions that
may delay, defer or prevent a transaction, including a change in control, that
might involve payment of a premium price for our common stock or otherwise be in
the best interests of our stockholders. Those provisions include the following:
 
     - the provision in the Charter that directors may be removed only for cause
       and only upon a two-thirds vote of stockholders, together with Bylaw
       provisions authorizing the Board of Directors to fill vacant
       directorships;
 
                                       15
<PAGE>   19
 
     - the provision in the Charter requiring a two-thirds vote of stockholders
       for any amendment of the Charter;
 
     - the requirement in the Bylaws that the request of the holders of 50% or
       more of our common stock is necessary for stockholders to call a special
       meeting;
 
     - the requirement of Maryland law that stockholders may only take action by
       written consent with the unanimous approval of all stockholders entitled
       to vote on the matter in question; and
 
     - the requirement in the Bylaws of advance notice by stockholders for the
       nomination of directors or proposal of business to be considered at a
       meeting of stockholders.
 
     These provisions may impede various actions by stockholders without
approval of our Board of Directors, which in turn may delay, defer or prevent a
transaction involving a change of control.
 
 We Could Change Our Investment and Financing Policies without a Vote of
 Stockholders
 
     Subject to our fundamental investment policy to maintain our qualification
as a REIT (unless a change is approved by the Board of Directors under certain
circumstances), the Board of Directors will determine our investment and
financing policies, our growth strategy and our debt, capitalization,
distribution and operating policies. Although the Board of Directors has no
present intention to revise or amend these strategies and policies, the Board of
Directors may do so at any time without a vote of stockholders. Accordingly,
stockholders will have no control over changes in our strategies and policies
(other than through the election of directors), and any such changes may not
serve the interests of all stockholders and could adversely affect our financial
condition or results of operations, including our ability to distribute cash to
stockholders.
 
 If We Issue Additional Securities, the Investment of Existing Stockholders Will
 Be Diluted
 
     We have authority to issue shares of common stock or other equity or debt
securities in exchange for property or otherwise. Similarly, we may cause the
Operating Partnership to issue additional Units in exchange for property or
otherwise. Existing stockholders will have no preemptive right to acquire any
additional securities issued by us or the Operating Partnership and any issuance
of additional equity securities could result in dilution of an existing
stockholder's investment.
 
 The Large Number of Shares Available for Future Sale Could Adversely Affect the
 Market Price of Our Common Stock
 
     We can not predict the effect, if any, that future sales of shares of our
common stock, or the availability of shares of our common stock for future sale,
will have on its market price. Sales of a substantial number of shares of our
common stock in the public market (or upon exchange of Units) or the perception
that such sales (or exchanges) might occur could adversely affect the market
price of our common stock. In connection with our initial public offering, we
agreed that we would not, and each of our original executive officers and
independent directors agreed that they would not, without the consent of Morgan
Stanley & Co. Incorporated, offer, sell, contract to sell, pledge, grant any
option, right or warrant to purchase, lend or otherwise transfer or dispose of,
directly or indirectly, any (other than in connection with mergers,
acquisitions, or similar transactions) shares of
 
                                       16
<PAGE>   20
 
our common stock, or any securities convertible into or exercisable for shares
of our common stock until, in the case of our original executive officers,
November 21, 1999, and in our case and the case of our independent directors,
November 21, 1998.
 
     The shares of common stock issued in the transactions involved in our
formation and all shares of common stock issuable upon the redemption of Units
will be deemed to be "restricted securities" within the meaning of Rule 144
under the Securities Act and may not be transferred unless registered under the
Securities Act or an exemption from registration is available, including any
exemption from registration provided under Rule 144. In general, upon
satisfaction of certain conditions, Rule 144 permits the holder to sell certain
amounts of restricted securities one year following the date of acquisition of
the restricted securities from us and, after two years, permits unlimited sales
by persons unaffiliated with us. On November 26, 1998, 74,710,153 shares of
common stock issued in our formation transactions became eligible for sale
pursuant to Rule 144, subject to the volume limitations and other conditions
imposed by Rule 144. Commencing generally on the first anniversary of the date
of acquisition of common Units (or such other date agreed to by the Operating
Partnership and the holders of the Units), the Operating Partnership may redeem
common Units at the request of the holders for cash (based on the fair market
value of an equivalent number of shares of common stock at the time of
redemption) or, at the Company's option, exchange the common Units for an equal
number of shares of common stock, subject to certain antidilution adjustments.
The Operating Partnership has issued 4,447,839 common Units to date, including
the 2,542,163 common Units held by the selling stockholders which became
exchangeable for shares of common stock on November 26, 1998. We have reserved
5,750,000 shares of common stock for issuance under our Stock Option and
Incentive Plan and, as of September 30, 1998, have granted to certain directors,
officers and employees options to purchase 3,133,750 shares of common stock (net
of forfeitures). To date we have granted 5,712 restricted shares of common
stock. In addition, we may issue additional shares of common stock or Units in
connection with the acquisition of properties. The registration statement of
which this prospectus is a part covers the issuance of 2,542,163 shares of
common stock upon the exchange of the common Units held by the selling
stockholders and the resale of those shares. In connection with the issuance of
common Units to other transferors of properties, and in connection with the
issuance of any Performance Units, we have agreed to file registration
statements covering the issuance of shares of common stock upon the exchange of
the common Units. We have also filed a registration statement with respect to
the shares of common stock issuable under our Stock Option and Incentive Plan.
These registration statements and registration rights generally allow shares of
common stock covered thereby, including shares of common stock issuable upon
exchange of Units, including Performance Units, or the exercise of options or
restricted shares of common stock, to be transferred or resold without
restriction under the Securities Act. However, pursuant to the terms and
conditions of the registration rights agreement that we entered into with the
selling stockholders, prior to the date upon which the Units would be eligible
for resale under Rule 144(k) under the Securities Act, as such rule may be
amended from time to time (or any similar rule or regulation hereafter adopted
by the SEC), each of the selling stockholders generally is limited to resales of
shares of common stock issued pursuant to this prospectus to the number of
shares which otherwise would be eligible for resale by that selling stockholder
pursuant to Rule 144, assuming the shares were issued on the same date as the
respective Units were issued. See "Plan of Distribution." We may also agree to
provide registration rights to any other person who may become an owner of
Units. See "Description of Certain Provisions of the Partnership
 
                                       17
<PAGE>   21
 
Agreement of the Operating Partnership -- Common Limited Partnership Units --
Registration Rights."
 
     Future sales of the shares of common stock described above could adversely
affect the market price of our common stock. The existence of Units, options and
shares of common stock reserved for issuance upon exchange of Units, and the
exercise of options and registration rights referred to above, also may
adversely affect the terms upon which we are able to obtain additional capital
through the sale of equity securities.
 
  Various Market Conditions Affect the Price of Our Common Stock
 
     As with other publicly-traded equity securities, the market price of our
common stock will depend upon various market conditions, which may change from
time to time. Among the market conditions that may affect the market price of
our common stock are the following:
 
     - the extent of investor interest in us;
 
     - the general reputation of REITs and the attractiveness of their equity
       securities in comparison to other equity securities (including securities
       issued by other real estate-based companies);
 
     - our financial performance; and
 
     - general stock and bond market conditions, including changes in interest
       rates on fixed income securities which may lead prospective purchasers of
       our common stock to demand a higher annual yield from future
       distributions. Such an increase in the required yield from distributions
       may adversely affect the market price of our common stock.
 
Other factors such as governmental regulatory action and changes in tax laws
could also have a significant impact on the future market price of our common
stock.
 
 Earnings and Cash Distributions, Asset Value and Market Interest Rates Affect
 the Price of Our Common Stock
 
     The market value of the equity securities of a REIT generally is based
primarily upon the market's perception of the REIT's growth potential and its
current and potential future earnings and cash distributions, and is based
secondarily upon the real estate market value of the underlying assets. For that
reason, shares of our common stock may trade at prices that are higher or lower
than the net asset value per share. To the extent we retain operating cash flow
for investment purposes, working capital reserves or other purposes, these
retained funds, while increasing the value of our underlying assets, may not
correspondingly increase the market price of our common stock. Our failure to
meet the market's expectation with regard to future earnings and cash
distributions likely would adversely affect the market price of our common
stock. Another factor that may influence the price of our common stock will be
the distribution yield on our common stock (as a percentage of the price of our
common stock) relative to market interest rates. An increase in market interest
rates might lead prospective purchasers of our common stock to expect a higher
distribution yield, which would adversely affect the market price of our common
stock. If the market price of our common stock declines significantly, we might
breach certain covenants with respect to debt obligations, which might adversely
affect our liquidity and our ability to make future acquisitions and pay
distributions to our stockholders.
 
                                       18
<PAGE>   22
 
  We Could Invest in Real Estate Mortgages
 
     We may invest in mortgages, and may do so as a strategy for ultimately
acquiring the underlying property. In general, investments in mortgages include
the risks that borrowers may not be able to make debt service payments or pay
principal when due, that the value of the mortgaged property may be less than
the principal amount of the mortgage note secured by the property and that
interest rates payable on the mortgages may be lower than our cost of funds to
acquire these mortgages. In any of these events, our funds from operations and
our ability to make distributions on, and the market price of, our common stock
could be adversely affected. "Funds from operations" means income (loss) from
operations before disposal of real estate properties, minority interests and
extraordinary items plus depreciation and amortization, excluding depreciation
of furniture, fixtures and equipment less funds from operations attributable to
minority interests in consolidated joint ventures which are not convertible into
shares of common stock.
 
GOVERNMENT REGULATIONS
 
     Many laws and governmental regulations are applicable to our properties and
changes in these laws and regulations, or their interpretation by agencies and
the courts, occur frequently.
 
  Costs of Compliance with Americans with Disabilities Act
 
     Under the Americans with Disabilities Act of 1990 (the "Americans with
Disabilities Act"), places of public accommodation must meet certain federal
requirements related to access and use by disabled persons. Compliance with the
Americans with Disabilities Act might require us to remove structural barriers
to handicapped access in certain public areas where such removal is "readily
achievable." If we fail to comply with the Americans with Disabilities Act, we
might be required to pay fines to the government or damages to private
litigants. The impact of application of the Americans with Disabilities Act to
our properties, including the extent and timing of required renovations, is
uncertain. If we are required to make unanticipated expenditures to comply with
the Americans with Disabilities Act, our cash flow and the amounts available for
distributions to our stockholders may be adversely affected.
 
  We Could Encounter Costly Environmental Problems
 
     Federal, state and local laws and regulations relating to the protection of
the environment impose liability on a current or previous owner or operator of
real estate for contamination resulting from the presence or discharge of
hazardous or toxic substances or petroleum products at the property. A current
or previous owner may be required to investigate and clean up contamination at
or migrating from a site. These laws typically impose liability and clean-up
responsibility without regard to whether the owner or operator knew of or caused
the presence of the contaminants. Even if more than one person may have been
responsible for the contamination, each person covered by the environmental laws
may be held responsible for all of the clean-up costs incurred. In addition,
third parties may sue the owner or operator of a site for damages based on
personal injury, property damage and/or other costs, including investigation and
clean-up costs, resulting from environmental contamination present at or
emanating from that site.
 
     Environmental Laws also govern the presence, maintenance and removal of
asbestos. These laws require that owners or operators of buildings containing
asbestos properly manage and maintain the asbestos, that they adequately inform
or train those who may
 
                                       19
<PAGE>   23
 
come into contact with asbestos and that they undertake special precautions,
including removal or other abatement in the event that asbestos is disturbed
during renovation or demolition of a building. These laws may impose fines and
penalties on building owners or operators for failure to comply with these
requirements and may allow third parties to seek recovery from owners or
operators for personal injury associated with exposure to asbestos fibers. Some
of our properties may contain asbestos-containing building materials.
 
     Some of our properties are leased or have been leased, in part, to owners
and operators of dry cleaners that operate on-site dry cleaning plants, to
owners and operators of gas stations or to owners or operators of other
businesses that use, store or otherwise handle petroleum products or other
hazardous or toxic substances. Some of these properties contain, or may have
contained, underground storage tanks for the storage of petroleum products and
other hazardous or toxic substances. These operations create a potential for the
release of petroleum products or other hazardous or toxic substances. Some of
our properties are adjacent to or near other properties that have contained or
currently contain underground storage tanks used to store petroleum products or
other hazardous or toxic substances. In addition, certain of our properties are
on, or are adjacent to or near other properties upon which others, including
former owners or tenants of the properties, have engaged or may in the future
engage in activities that may release petroleum products or other hazardous or
toxic substances.
 
     All of our properties were subject to a Phase I or similar environmental
assessments by independent environmental consultants at the time of acquisition
or shortly after acquisition. Phase I assessments are intended to discover and
evaluate information regarding the environmental condition of the surveyed
property and surrounding properties. Phase I assessments generally include an
historical review, a public records review, an investigation of the surveyed
site and surrounding properties, and preparation and issuance of a written
report, but do not include soil sampling or subsurface investigations and
typically do not include an asbestos survey. We may perform additional Phase II
testing if recommended by the independent environmental consultant. Phase II
testing may include the collection and laboratory analysis of soil and
groundwater samples, completion of surveys for asbestos-containing building
materials, and any other testing that the consultant considers prudent in order
to test for the presence of hazardous materials. Some of the environmental
assessments of our properties do not contain a comprehensive review of the past
uses of the properties and/or the surrounding properties.
 
     None of the environmental assessments of our properties has revealed any
environmental liability that we believe would have a material adverse effect on
our financial condition or results of operations taken as a whole, and we are
not aware of any such material environmental liability. Nonetheless, it is
possible that the assessments do not reveal all environmental liabilities and
that there are material environmental liabilities of which we are unaware.
Moreover, future laws, ordinances or regulations may impose material
environmental liability and the current environmental condition of our
properties may be affected by tenants, by the condition of land, by operations
in the vicinity of the properties (such as releases from underground storage
tanks), or by third parties unrelated to us. If the costs of compliance with
environmental laws and regulations now existing or adopted in the future exceed
our budgets for these items, our financial condition, results of operations,
cash flow and ability to pay distributions on, and the market price of, our
common stock could be adversely affected.
 
                                       20
<PAGE>   24
 
 Our Financial Condition could be Adversely Affected if We Fail to Comply with
 Other Regulations
 
     Our properties are also subject to various federal, state and local
regulatory requirements such as state and local fire and life safety
requirements. If we fail to comply with these requirements, we might incur fines
by governmental authorities or be required to pay awards of damages to private
litigants. We believe that our properties are currently in substantial
compliance with all such regulatory requirements. However, these requirements
may change or new requirements may be imposed which could require significant
unanticipated expenditures by us. Any such unanticipated expenditures could have
an adverse effect on our financial condition, results of operations, cash flow
and ability to pay distributions on, and the market price of, our common stock.
 
FEDERAL INCOME TAX RISKS
 
 Our Failure to Qualify as a REIT Would Have Serious Adverse Consequences to Our
 Stockholders
 
     We intend to operate so as to qualify as a REIT under the Code. We believe
that we have been organized and have operated in a manner which would allow us
to qualify as a REIT under the Code beginning with our taxable year ended
December 31, 1997. However, it is possible that we have been organized or have
operated in a manner which would not allow us to qualify as a REIT, or that our
future operations could cause us to fail to qualify. Qualification as a REIT
requires us to satisfy numerous requirements (some on an annual and quarterly
basis) established under highly technical and complex Code provisions for which
there are only limited judicial and administrative interpretations, and involves
the determination of various factual matters and circumstances not entirely
within our control. For example, in order to qualify as a REIT, at least 95% of
our gross income in any year must be derived from qualifying sources, and we
must pay dividends to stockholders aggregating annually at least 95% of our REIT
taxable income (determined without regard to the dividends paid deduction and by
excluding capital gains). These provisions and the applicable treasury
regulations are more complicated in our case because we hold our assets in
partnership form. Legislation, new regulations, administrative interpretations
or court decisions could significantly change the tax laws with respect to
qualification as a REIT or the federal income tax consequences of such
qualification. However, we are not aware of any pending tax legislation that
would adversely affect our ability to operate as a REIT.
 
     If we fail to qualify as a REIT in any taxable year, we will be subject to
federal income tax (including any applicable alternative minimum tax) on our
taxable income at regular corporate rates. Unless we are entitled to relief
under certain statutory provisions, we would be disqualified from treatment as a
REIT for the four taxable years following the year during which we lost
qualification. If we lose our REIT status, our net earnings available for
investment or distribution to stockholders would be significantly reduced for
each of the years involved. In addition, we would no longer be required to make
distributions to stockholders. See "Certain Federal Income Tax
Considerations -- Failure to Qualify."
 
  We Pay Some Taxes
 
     Even if we qualify as a REIT, we will be subject to certain federal, state
and local taxes on our income and property. In addition, the net taxable income,
if any, from the activities conducted through the Preferred Stock Subsidiaries
(which we discuss below
 
                                       21
<PAGE>   25
 
under "-- Preferred Stock Subsidiaries") will be subject to federal and state
income tax. See "Certain Federal Income Tax Considerations -- Other Tax
Consequences."
 
WE ARE DEPENDENT ON OUR KEY PERSONNEL
 
     We depend on the efforts of our executive officers, particularly Messrs.
Abbey, Moghadam and Burke, the Chairman of our Investment Committee, our Chief
Executive Officer and the Chairman of our Board of Directors, respectively.
While we believe that we could find suitable replacements for these key
personnel, the loss of their services or the limitation of their availability
could adversely affect our financial condition, results of operations, cash flow
and ability to pay distributions on, and the market price of, our common stock.
We do not have employment agreements with any of our executive officers.
 
WE MAY BE UNABLE TO MANAGE OUR GROWTH
 
     Our business has grown rapidly and continues to grow through property
acquisitions. If we fail to effectively manage our growth, our financial
condition, results of operations, cash flow and ability to pay distributions on,
and the market price of, our common stock could be adversely affected.
 
THE PREFERRED STOCK SUBSIDIARIES
 
  We do not Control the Activities of the Preferred Stock Subsidiaries
 
     The Operating Partnership owns 100% of the non-voting preferred stock of
AMB Investment Management and Headlands Realty Corporation (representing
approximately 95% of the economic interest in each entity). We refer to these
entities as the "Preferred Stock Subsidiaries." Certain of our executive
officers and an officer of AMB Investment Management own all of the outstanding
voting common stock of AMB Investment Management (representing approximately 5%
of the economic interest in AMB Investment Management). Certain of our executive
officers and a director of Headlands Realty Corporation own all of the
outstanding voting common stock of Headlands Realty Corporation (representing
approximately 5% of the economic interest in Headlands Realty Corporation). The
ownership structure of the Preferred Stock Subsidiaries permits us to share in
the income of the Preferred Stock Subsidiaries while maintaining our status as a
REIT. We receive substantially all of the economic benefit of the businesses
carried on by the Preferred Stock Subsidiaries through our right to receive
dividends through the Operating Partnership. However, we are not able to elect
the Preferred Stock Subsidiaries' directors or officers and, as a result, we do
not have the ability to influence the operation of the Preferred Stock
Subsidiaries or to require that the Preferred Stock Subsidiaries' boards of
directors declare and pay cash dividends on the non-voting stock of the
Preferred Stock Subsidiaries held by the Operating Partnership. The boards of
directors and management of the Preferred Stock Subsidiaries might implement
business policies or decisions that would not have been implemented by persons
controlled by us and that may be adverse to the interests of our stockholders or
that may adversely impact our financial condition, results of operations, cash
flow and ability to pay distributions on, and the market price of, our common
stock. In addition, the Preferred Stock Subsidiaries are subject to tax on their
income, reducing their cash available for distribution to the Operating
Partnership.

<PAGE>   26
 
 AMB Investment Management may not be able to Generate Sufficient Fees
 
     Fees earned by AMB Investment Management depend on various factors
affecting the ability to attract and retain investment management clients and
the overall returns achieved on managed assets. These factors are beyond our
control. AMB Investment Management's failure to attract investment management
clients or achieve sufficient overall returns on managed assets could reduce its
ability to make distributions on the stock owned by the Operating Partnership
and could also limit co-investment opportunities to the Operating Partnership.
This would limit the Operating Partnership's ability to generate rental revenues
from such co-investments and use the co-investment program as a source to
finance property acquisitions and leverage acquisition opportunities.

                                  THE COMPANY
 
GENERAL
 
     We are one of the largest publicly-traded real estate companies in the
United States. As of November 30, 1998, we owned 587 industrial buildings
located in 26 markets throughout the United States, including 40 industrial
buildings acquired since September 30, 1998, and 38 retail centers located in 16
markets throughout the United States, including one center acquired since
September 30, 1998. As of September 30, 1998, our industrial buildings,
principally warehouse distribution properties, encompassed approximately 53.1
million rentable square feet and, as of the same date, were 95.9% leased to over
1,500 tenants. As of September 30, 1998, our retail centers, principally
grocer-anchored community shopping centers, encompassed approximately 6.9
million rentable square feet and, as of the same date, were 94.8% leased to over
900 tenants. We own substantially all of our assets, and conduct substantially
all of our business, through the Operating Partnership and its subsidiaries.
 
     We are engaged in the business of acquiring and operating industrial
buildings and community shopping centers in target markets nationwide. We are
led by Hamid R. Moghadam, our Chief Executive Officer and one of our three
founders. Douglas D. Abbey and T. Robert Burke, our other two founders, also
play active roles in our operations as the Chairman of our Investment Committee
and the Chairman of our Board of Directors, respectively. Our 10 executive
officers have an average of 23 years of experience in the real estate industry
and have worked together for an average of nine years building the AMB real
estate business.
 
     The Company was organized in November 1997 and commenced operations upon
the completion of the initial public offering on November 26, 1997. We operate
as a self-administered and self-managed real estate company and believe that we
have qualified and that we will continue to qualify as a REIT for federal income
tax purposes beginning with the year ended December 31, 1997.
 
STRATEGIC ALLIANCE PROGRAMS(TM)
 
     We believe that our strategy of forming strategic alliances with local and
regional real estate experts and institutional investors provides us with growth
opportunities, access to private capital and flexibility in the markets in which
we operate. We have been a leader in forming these alliances through the
following Strategic Alliance Programs(TM).
 
     - Institutional Alliance Program(TM): Our strategy for our Institutional
       Alliance Program(TM) is to form joint ventures with institutional
       investors through the co-investment program of AMB Investment Management.
       This program provides access to private capital, including during those
       times when the public markets are less attractive.
 
     - UPREIT Alliance Program(TM): Through our UPREIT Alliance Program(TM), we
       issue Operating Partnership Units in exchange for properties, thereby
       providing additional growth for our portfolio.
 
     - Development Alliance Program(TM): Our strategy for our Development
       Alliance Program(TM) is to enhance our development capability by forming
       alliances with development firms with a strong local presence and
       expertise.
 
                                       24
<PAGE>   28
 
     - Customer Alliance Program(TM): Through our Customer Alliance Program(TM),
       we seek to build long-term working relationships with major tenants with
       the assistance of leading local and national leasing firms.
 
     - Management Alliance Program(TM): Our strategy for our Management Alliance
       Program(TM) is to develop close relationships with, and outsource
       property management to, local property managers that we believe are among
       the best in their respective markets. These local property managers
       provide us with local market information related to tenant activity and
       acquisition and development opportunities as well as economies of scale.
 
THE PREFERRED STOCK SUBSIDIARIES
 
     AMB Investment Management provides real estate investment management
services on a fee basis to clients, including certain clients of our
predecessor, AMB Institutional Realty Advisors, Inc. These clients did not
participate in our formation transactions. In general, we presently intend to
co-invest with clients of AMB Investment Management, to the extent the clients
newly commit investment capital, through partnerships, limited liability
companies and joint ventures. We generally use a co-investment formula with each
client whereby we will own at least a 20% interest in all ventures. As of
September 30, 1998, we had consummated four co-investment transactions through
one partnership. Headlands Realty Corporation invests in properties and may in
the future engage in or acquire interests in entities that engage in the
management, leasing and development of properties and similar activities.
 
RECENT DEVELOPMENTS

                          DESCRIPTION OF CAPITAL STOCK
 
     We have summarized certain terms and provisions of our capital stock in
this section. This summary is not complete. For more detail you should refer to
the Maryland General Corporation Law (the "MGCL"), our Charter and our Bylaws,
which we have filed as exhibits to the registration statement of which this
prospectus is a part. See "Where You Can Find More Information."
 
COMMON STOCK
 
     Our Charter provides that we are authorized to issue 500,000,000 shares of
common stock, $.01 par value per share. As of November 30, 1998, we had
85,874,513 shares of common stock issued and outstanding. Each outstanding share
of common stock entitles the holder to one vote on all matters presented to
stockholders generally for a vote, including the election of directors. Except
as otherwise required by law and except as provided in any resolution adopted by
the Board of Directors establishing any other class or series of stock, the
holders of common stock possess the exclusive voting power, subject to the
provisions of the Charter regarding the ownership of shares of common stock in
excess of the ownership limit or any other limit specified in the Charter, or
otherwise permitted by the Board of Directors. Holders of shares of common stock
do not have any conversion, exchange, sinking fund, redemption or appraisal
rights or any preemptive rights to subscribe for any of our securities or
cumulative voting rights in the election of directors. All shares of common
stock that are issued and outstanding are duly authorized, fully paid and
nonassessable. Subject to the preferential rights of any other shares or series
or classes of stock, including the Series A Preferred Stock, the Series B
Preferred Stock and the Series C Preferred Stock (see "-- Preferred Stock"), and
to the provisions of the Charter regarding ownership of shares of common stock
in excess of the ownership limit, or such other limit specified in the Charter
or as otherwise permitted by the Board of Directors, we may pay distributions to
the holders of shares of common stock if and when authorized and declared by the
Board of Directors out of funds legally available for distribution. We intend to
continue to make quarterly distributions on outstanding shares of common stock.
 
     Under the MGCL, stockholders are generally not liable for our debts or
obligations. If we liquidate, subject to the right of any holders of preferred
stock, including the Series A Preferred Stock, the Series B Preferred Stock and
the Series C Preferred Stock (see "-- Preferred Stock") to receive preferential
distributions, each outstanding share of common stock will be entitled to
participate pro rata in the assets remaining after payment of, or adequate
provision for, all of our known debts and liabilities, including debts and
liabilities arising out of our status as general partner of the Operating
Partnership.
 
     Subject to the provisions of our Charter regarding the ownership of shares
of common stock in excess of the ownership limit, or such other limit specified
in the Charter, or as otherwise permitted by the Board of Directors as described
below, all shares of common stock have equal distribution, liquidation and
voting rights, and have no preference or exchange rights.
 
     Under the MGCL, a Maryland corporation generally cannot dissolve, amend its
charter, merge, sell all or substantially all of its assets, engage in a share
exchange or engage in similar transactions outside the ordinary course of
business unless approved by the affirmative vote of at least two-thirds of the
votes entitled to be cast on the matter unless a lesser percentage (but not less
than a majority of all of the votes entitled to be cast on the matter) is set
forth in the corporation's charter. Under the MGCL, the term
 
                                       27
<PAGE>   31
 
"substantially all of the Company's assets" is not defined and is, therefore,
subject to Maryland common law and to judicial interpretation and review in the
context of the unique facts and circumstances of any particular transaction. Our
Charter does not provide for a lesser percentage in any of the above situations.
 
     Our Charter authorizes the Board of Directors to reclassify any unissued
shares of common stock into other classes or series of classes of stock and to
establish the number of shares in each class or series and to set the
preferences, conversion and other rights, voting powers, restrictions,
limitations and restrictions on ownership, limitations as to dividends or other
distributions, qualifications and terms or conditions of redemption for each
class or series.
 
PREFERRED STOCK
 
     Our Charter provides that we are authorized to issue 100,000,000 shares of
preferred stock, $.01 par value per share, of which 4,600,000 shares are of a
separate class designated as Series A Preferred Stock, 1,300,000 shares are of a
separate class designated as Series B Preferred Stock and 2,200,000 shares are
of a separate class designated as Series C Preferred Stock. The Series B
Preferred Stock is issuable in exchange, on a one for one basis, subject to
adjustment, for the Series B Preferred Units. The Series C Preferred Stock is
issuable in exchange, on a one for one basis, subject to adjustment, for the AMB
Property II Series C Preferred Units. As of November 30, 1998, we had 4,000,000
shares of Series A Preferred Stock issued and outstanding. As of the same date,
we had 1,300,000 shares of Series B Preferred Stock and 2,200,000 shares of
Series C Preferred Stock reserved for issuance but not issued or outstanding. We
may issue additional shares of preferred stock from time to time, in one or more
classes, as authorized by the Board of Directors. Prior to the issuance of
shares of each class of preferred stock, the Board of Directors is required by
the MGCL and the Charter to fix for each class the terms, preferences,
conversion or other rights, voting powers, restrictions, limitations as to
distributions, qualifications and terms or conditions of redemption, as
permitted by Maryland law. Because the Board of Directors has the power to
establish the preferences, powers and rights of each class of preferred stock,
it may afford the holders of any class of preferred stock preferences, powers
and rights, voting or otherwise, senior to the rights of holders of shares of
common stock. The issuance of preferred stock could have the effect of delaying
or preventing a change of control that might involve a premium price for holders
of shares of common stock or otherwise be in their best interest.
 
     Series A Preferred Stock. The Series A Preferred Stock ranks, with respect
to dividends and in the event we voluntarily or involuntarily liquidate,
dissolve or wind up:
 
     - senior to all classes or series of common stock and to all of our equity
       securities that provide that they rank junior to the Series A Preferred
       Stock;
 
     - junior to all equity securities issued by us which rank senior to the
       Series A Preferred Stock; and
 
     - on a parity with all equity securities issued by us (including the Series
       B Preferred Stock and the Series C Preferred Stock) other than those
       referred to in the bullet points above. The term "equity securities" does
       not include convertible debt securities.
 
     Holders of the Series A Preferred Stock are entitled to receive, when and
as authorized by the Board of Directors out of funds legally available for
dividends, cumulative preferential cash dividends at the rate of 8 1/2% of the
liquidation preference per
 
                                       28
<PAGE>   32
 
annum (equivalent to $2.125 per annum per share of Series A Preferred Stock).
Dividends on the Series A Preferred Stock accumulate on a daily basis and are
payable quarterly in arrears on the 15th day of each January, April, July and
October. Except as provided below, unless full cumulative dividends on the
Series A Preferred Stock have been or at the same time are declared and paid or
declared and a sum sufficient for payment set apart for payment for all past
dividend periods and the then current dividend period, no dividends (other than
in common stock or other equity securities ranking junior to the Series A
Preferred Stock) may be declared or paid or set aside for payment or other
dividend be declared or made upon the common stock or any other equity
securities ranking junior to or on a parity with the Series A Preferred Stock
(including the Series B Preferred Stock and the Series C Preferred Stock), nor
may any common stock or any other equity securities ranking junior to or on a
parity with the Series A Preferred Stock (including the Series B Preferred Stock
and the Series C Preferred Stock) be redeemed, purchased or otherwise acquired
for any consideration (or any monies be paid to or made available for a sinking
fund for the redemption of any such securities) by us (except by conversion into
or exchange for other equity securities ranking junior to the Series A Preferred
Stock and pursuant to the provisions of our Charter providing for limitations on
ownership and transfer in order to ensure that we remain qualified as a REIT).
When dividends are not paid in full (or a sum sufficient for such full payment
is not so set apart) upon the Series A Preferred Stock and any other equity
securities ranking on a parity with the Series A Preferred Stock (including the
Series B Preferred Stock and the Series C Preferred Stock), all dividends
declared upon the Series A Preferred Stock and any other equity securities
ranking on a parity with the Series A Preferred Stock (including the Series B
Preferred Stock and the Series C Preferred Stock) will be declared pro rata so
that the amount of dividends declared per share of Series A Preferred Stock and
each such other equity securities shall bear to each other the same ratio that
accumulated dividends per share of Series A Preferred Stock and such other
equity securities (which shall not include any accumulation in respect of unpaid
dividends for prior dividend periods if such other equity securities do not have
a cumulative dividend) bear to each other. Dividends on the Series A Preferred
Stock will accumulate whether or not we have funds legally available for the
payment of dividends and whether or not we declare dividends. If we designate
any portion of a dividend as a "capital gain dividend," a holder's share of the
capital gain dividend will be an amount that bears the same ratio to the total
amount of dividends (as determined for federal income tax purposes) paid to the
holder for the year as the aggregate amount designated as a capital gain
dividend bears to the aggregate amount of all dividends (as determined for
federal income tax purposes) paid on all classes of shares for the year.
 
     In the event that we voluntarily or involuntarily liquidate, dissolve or
wind up, the holders of the Series A Preferred Stock are entitled to receive out
of our assets legally available for distribution to our stockholders remaining
after payment or provision for payment of all of our debts and liabilities, a
liquidation preference, in cash, of $25.00 per share, plus an amount equal to
any accumulated and unpaid dividends to the date of such payment, before any
distribution of assets is made to holders of common stock or any other equity
securities that rank junior to the Series A Preferred Stock. After payment of
the full amount of the liquidating distributions to which they are entitled, the
holders of the Series A Preferred Stock will have no right or claim to any of
our remaining assets. Our consolidation or merger with or into any other entity,
a merger of another entity with or into us, a statutory share exchange or the
sale, lease, transfer or conveyance of all or substantially all of our property
or business do not constitute a liquidation, dissolution or winding up for
purposes of triggering the liquidation preference.
 
                                       29
<PAGE>   33
 
     If we voluntarily or involuntarily liquidate, dissolve or wind up and our
assets are insufficient to make full payment to holders of the Series A
Preferred Stock and the corresponding amounts payable on all shares of other
classes or series of equity securities ranking on a parity with the Series A
Preferred Stock, then the holders of the Series A Preferred Stock and all other
such classes or series of equity securities will share ratably in any such
distribution of assets in proportion to the full liquidating distributions to
which they would otherwise be entitled.
 
     The Series A Preferred Stock has no stated maturity and is not subject to
mandatory redemption or any sinking fund. We cannot redeem the Series A
Preferred Stock prior to July 27, 2003. On and after July 27, 2003, we can
redeem the Series A Preferred Stock for cash at our option, in whole or from
time to time in part, at a redemption price of $25.00 per share, plus
accumulated and unpaid dividends, if any, to the redemption date. We must pay
the redemption price (other than the portion of the redemption price consisting
of accumulated and unpaid dividends) solely out of the sale proceeds of other
equity securities, which may include other classes or series of preferred stock.
In certain circumstances related to our maintenance of our ability to qualify as
a REIT for federal income tax purposes, we may redeem shares of Series A
Preferred Stock. See "-- Restrictions on Ownership and Transfer of Capital
Stock."
 
     Holders of Series A Preferred Stock have no voting rights, except as
described below. If we do not pay dividends on the Series A Preferred Stock for
six or more quarterly periods (whether or not consecutive), holders of the
Series A Preferred Stock (voting separately as a class with all other classes or
series of equity securities upon which like voting rights have been conferred
and are exercisable) will be entitled to vote for the election of two additional
directors to serve on our Board of Directors until we have eliminated all
dividend arrearages with respect to the Series A Preferred Stock. So long as any
shares of Series A Preferred Stock remain outstanding, we may not, without the
affirmative vote or consent of at least two-thirds of the votes entitled to be
cast by the holders of outstanding shares of Series A Preferred Stock (the
Series A Preferred Stock voting separately as a class):
 
     - authorize or create, or increase the authorized or issued amount of, any
       class or series of stock ranking senior to the Series A Preferred Stock;
 
     - reclassify any of our authorized stock into any class or series of stock
       ranking senior to the Series A Preferred Stock;
 
     - create, authorize or issue any obligation or security convertible into,
       exchangeable or exercisable for, or evidencing the right to purchase, any
       class or series of stock ranking senior to the Series A Preferred Stock;
       or
 
     - amend, alter or repeal the provisions of our Charter, whether by merger
       or consolidation or otherwise, so as to materially and adversely affect
       any right, preference, privilege or voting power of the Series A
       Preferred Stock.
 
     With respect to the occurrence of any of the events set forth in the fourth
bullet point above, so long as shares of Series A Preferred Stock (or shares
issued by a surviving entity in substitution for shares of the Series A
Preferred Stock) remain outstanding with the terms materially unchanged, taking
into account that upon the occurrence of such an event, we may not be the
surviving entity, the occurrence of any such event will not be considered to
materially and adversely affect rights, preferences, privileges or voting powers
of holders of Series A Preferred Stock. Any increase in the amount of the
authorized preferred stock, the creation or issuance of any other class or
series of preferred stock or
 
                                       30
<PAGE>   34
 
any increase in the amount of authorized Series A Preferred Stock or any other
class or series of preferred stock, in each case ranking on a parity with or
junior to the Series A Preferred Stock will not be considered to materially and
adversely affect such rights, preferences, privileges or voting powers.
 
     In accordance with the terms of the Partnership Agreement, we contributed
the net proceeds of the sale of the Series A Preferred Shares to the Operating
Partnership and the Operating Partnership issued to us Series A Preferred Units
that mirror the rights, preferences and other terms of the Series A Preferred
Stock. The Operating Partnership is required to make all required distributions
on the Series A Preferred Units prior to any distribution of cash or assets to
the holders of any other Units or any other equity interests in the Operating
Partnership, except for any other series of preferred Units ranking on a parity
with the Series A Preferred Units as to dividends or voluntary or involuntary
liquidation, dissolution or winding up of the Operating Partnership. The
Operating Partnership has no preferred Units, other than the Series A Preferred
Units and the Series B Preferred Units, outstanding or any other equity
interests ranking prior to any other Units or any other equity interests in the
Operating Partnership.
 
     Series B Preferred Stock. We currently have no shares of Series B Preferred
Stock issued or outstanding. The Series B Preferred Stock is issuable upon
exchange of the Series B Preferred Units, as described under "Description of
Certain Provisions of the Partnership Agreement of the Operating
Partnership -- Series B Preferred Units -- Exchange Rights." The Series B
Preferred Stock ranks, with respect to dividends and in the event we voluntarily
or involuntarily liquidate, dissolve or wind up:
 
     - senior to all classes or series of common stock and to all of our equity
       securities that provide that they rank junior to the Series B Preferred
       Stock;
 
     - junior to all equity securities issued by us which rank senior to the
       Series B Preferred Stock; and
 
     - on a parity with all equity securities issued by us (including the Series
       A Preferred Stock and the Series C Preferred Stock) other than those
       referred to in the bullet points above. The term "equity securities" does
       not include convertible debt securities.
 
     If ever issued, the Series B Preferred Stock will entitle the holders to
receive, when and as authorized by the Board of Directors out of funds legally
available for dividends, cumulative preferential cash dividends at the rate of
8 5/8% of the liquidation preference per annum (equivalent to $4.3125 per annum
per share of Series B Preferred Stock). Dividends on the Series B Preferred
Stock accumulate on a daily basis and are payable quarterly in arrears on the
15th day of each January, April, July and October. Except as provided below,
unless full cumulative dividends on the Series B Preferred Stock have been or at
the same time are declared and paid or declared and a sum sufficient for payment
set apart for payment for all past dividend periods and the then current
dividend period, no distributions (other than in common stock or other equity
securities ranking junior to the Series B Preferred Stock) may be declared or
paid or set aside for payment or other dividend be declared or made upon the
common stock or any other equity securities ranking junior to or on a parity
with the Series B Preferred Stock (including the Series A Preferred Stock and
the Series C Preferred Stock), nor may any common stock or any other equity
securities ranking junior to or on a parity with the Series B Preferred Stock
(including the Series A Preferred Stock and the Series C Preferred Stock) be
redeemed, purchased or otherwise acquired for any consideration (or any monies
be paid
 
                                       31
<PAGE>   35
 
to or made available for a sinking fund for the redemption of any such
securities) by us (except by conversion into or exchange for other equity
securities ranking junior to the Series B Preferred Stock and pursuant to the
provisions of our Charter providing for limitations on ownership and transfer in
order to ensure that we remain qualified as a REIT). When dividends are not paid
in full (or a sum sufficient for such full payment is not so set apart) upon the
Series B Preferred Stock and any other equity securities ranking on a parity
with the Series B Preferred Stock (including the Series A Preferred Stock and
the Series C Preferred Stock), all dividends declared upon the Series B
Preferred Stock and any other equity securities ranking on a parity with the
Series B Preferred Stock (including the Series A Preferred Stock and the Series
C Preferred Stock) will be declared pro rata so that the amount of dividends
declared per share of Series B Preferred Stock and each such other equity
securities shall bear to each other the same ratio that accumulated dividends
per share of Series B Preferred Stock and such other equity securities (which
shall not include any accumulation in respect of unpaid dividends for prior
dividend periods if such other equity securities do not have a cumulative
dividend) bear to each other. Dividends on the Series B Preferred Stock will
accumulate whether or not we have funds legally available for the payment of
dividends and whether or not we declare dividends. If we designate any portion
of a dividend as a "capital gain dividend," a holder's share of the capital gain
dividend will be an amount that bears the same ratio to the total amount of
dividends (as determined for federal income tax purposes) paid to the holder for
the year as the aggregate amount designated as a capital gain dividend bears to
the aggregate amount of all dividends (as determined for federal income tax
purposes) paid on all classes of shares for the year.
 
     In the event that we voluntarily or involuntarily liquidate, dissolve or
wind up following the issuance of the Series B Preferred Stock, the holders of
the Series B Preferred Stock will be entitled to receive out of our assets
legally available for distribution to our stockholders remaining after payment
or provision for payment of all of our debts and liabilities, a liquidation
preference, in cash, of $50.00 per share, plus an amount equal to any
accumulated and unpaid dividends to the date of such payment, before any
distribution of assets is made to holders of common stock or any other equity
securities that rank junior to the Series B Preferred Stock. After payment of
the full amount of the liquidating distributions to which they are entitled, the
holders of the Series B Preferred Stock will have no right or claim to any of
our remaining assets. Our consolidation or merger with or into any other entity,
a merger of another entity with or into us, a statutory share exchange or the
sale, lease, transfer or conveyance of all or substantially all of our property
or business do not constitute a liquidation, dissolution or winding up for
purposes of triggering the liquidation preference.
 
     If we voluntarily or involuntarily liquidate, dissolve or wind up following
the issuance of Series B Preferred Stock and our assets are insufficient to make
full payment to the holders of the Series B Preferred Stock and the
corresponding amounts payable on all shares of other classes or series of equity
securities ranking on a parity with the Series B Preferred Stock as to
liquidation rights (including the Series A Preferred Stock and the Series C
Preferred Stock) then the holders of the Series B Preferred Stock and all other
such classes or series of equity securities will share ratably in any such
distribution of assets in proportion to the full liquidating distributions to
which they would otherwise be entitled.
 
     The Series B Preferred Stock has no stated maturity and is not subject to
mandatory redemption or any sinking fund. If issued, we cannot redeem the Series
B Preferred Stock prior to November 12, 2003. On and after November 12, 2003, we
can redeem the
 
                                       32
<PAGE>   36
 
Series B Preferred Stock for cash at our option, in whole or from time to time
in part, at a redemption price of $50.00 per share, plus accumulated and unpaid
dividends, if any, to the redemption date. We must pay the redemption price
(other than the portion of the redemption price consisting of accumulated and
unpaid dividends) solely out of the sale proceeds of other equity securities,
which may include other classes or series of preferred stock. In certain
circumstances related to our maintenance of our ability to qualify as a REIT for
federal income tax purposes, we may redeem shares of Series B Preferred Stock.
See "-- Restrictions on Ownership and Transfer of Capital Stock."
 
     Holders of Series B Preferred Stock will have no voting rights, except as
described below. If we do not pay dividends on the Series B Preferred Stock for
six or more quarterly periods (whether or not consecutive), holders of the
Series B Preferred Stock (voting separately as a class with all other classes or
series of equity securities upon which like voting rights have been conferred
and are exercisable) will be entitled to vote for the election of two additional
directors to serve on our Board of Directors until we have eliminated all
dividend arrearages with respect to the Series B Preferred Stock. So long as any
shares of Series B Preferred Stock remain outstanding, we may not, without the
affirmative vote or consent of at least two-thirds of the votes entitled to be
cast by the holders of the outstanding shares of Series B Preferred Stock (the
Series B Preferred Stock voting separately as a class):
 
     - authorize or create, or increase the authorized or issued amount of, any
       class or series of stock ranking senior to the Series B Preferred Stock;
 
     - reclassify any of our authorized stock into any class or series of stock
       ranking senior to the Series B Preferred Stock;
 
     - designate or create, or increase the authorized or issued amount of, or
       reclassify, any authorized shares into, any preferred stock ranking on a
       parity with the Series B Preferred Stock or create, authorize or issue
       any obligations or securities convertible into any such shares, but only
       to the extent such stock is issued to one of our affiliates; or
 
     - either consolidate, merge into or with, or convey, transfer or lease our
       assets substantially as an entirety, to any corporation or other entity,
       or amend, alter or repeal the provisions of our Charter, whether by
       merger or consolidation or otherwise, in each case so as to materially
       and adversely affect the powers, special rights, preferences, privileges
       or voting power of the Series B Preferred Stock.
 
     With respect to the occurrence of any of the events set forth in the fourth
bullet point above, so long as we are either the surviving entity and shares of
Series B Preferred Stock remain outstanding with the terms materially unchanged
or the resulting, surviving or transferee entity is a corporation organized
under the laws of any state and substitutes for the Series B Preferred Stock
other preferred stock having substantially the same terms and rights as the
Series B Preferred Stock, the occurrence of any such event will not be
considered to materially and adversely affect rights, preferences, privileges or
voting powers of holders of Series B Preferred Stock. Any increase in the amount
of authorized preferred stock, the creation or issuance of any other class or
series of preferred stock or any increase in an amount of authorized shares of
each class or series, in each case ranking on a parity with or junior to the
Series B Preferred Stock will not be considered to materially and adversely
affect such rights, preferences, privileges or voting powers.
 
     We have granted certain registration rights with respect to any shares of
Series B Preferred Stock that we may issue upon exchange of the Series B
Preferred Units. See

"Description of Certain Provisions of the Partnership Agreement of the Operating
Partnership -- Series B Preferred Units -- Registration Rights."
 
     Series C Preferred Stock. We currently have no shares of Series C Preferred
Stock issued or outstanding. The Series C Preferred Stock is issuable upon
exchange of the AMB Property II Series C Preferred Units. The AMB Property II
Series C Preferred Units are exchangeable in whole at any time on or after
November 24, 2008, at the option of 51% of the holders of all outstanding AMB
Property II Series C Preferred Units, on a one for one basis, subject to
adjustment, for shares of our Series C Preferred Stock. In addition, the AMB
Property II Series C Preferred Units are exchangeable in whole at any time at
the option of 51% of the holders of all outstanding AMB Property II Series C
Preferred Units if:
 
     - any AMB Property II Series C Preferred Unit shall not have received full
       distributions with respect to six prior quarterly distribution periods
       (whether or not consecutive); or
 
     - AMB Property Holding Corporation, the general partner of AMB Property II,
       or one of its subsidiaries takes the position, and a holder or holders of
       AMB Property II Series C Preferred Units receive an opinion of
       independent counsel that AMB Property II is, or upon the happening of a
       certain event likely will be, a "publicly traded partnership" within the
       meaning of the Code.
 
     The AMB Property II Series C Preferred Units are exchangeable in whole for
shares of Series C Preferred Stock at any time after November 24, 2001 and prior
to November 24, 2008 at the option of 51% of the holders of all outstanding AMB
Property II Series C Preferred Units if those holders deliver to AMB Property
Holding Corporation a private letter ruling or an opinion of independent counsel
to the effect that an exchange of the AMB Property II Series C Preferred Units
at that time would not cause the AMB Property II Series C Preferred Units to be
considered "stock and securities" within the meaning of the Code for purposes of
determining whether the holder of AMB Property II Series C Preferred Units is an
"investment company" under the Code.
 
     The AMB Property II Series C Preferred Units are also exchangeable in whole
at any time for shares of Series C Preferred Stock, if initial purchasers of the
AMB Property II Series C Preferred Units holding 51% of all outstanding AMB
Property II Series C Preferred Units determine, (regardless of whether held by
the initial purchasers) if:
 
     - AMB Property II reasonably determines that the assets and income of AMB
       Property II for a taxable year after 1998 would not satisfy the income
       and assets tests of the Code for such taxable year if AMB Property II
       were a REIT; or
 
     - any holder of AMB Property II Series C Preferred Units delivers to AMB
       Property II and AMB Property Holding Corporation an opinion of
       independent counsel to the effect that (based on the assets and income of
       AMB Property II for a taxable year after 1998) AMB Property II would not
       satisfy the income and assets tests of the Code for such taxable year if
       AMB Property II were a REIT and that such failure would create a
       meaningful risk that a holder of AMB Property II Series C Preferred Units
       would fail to maintain qualification as a REIT.
 
     In lieu of an exchange for Series C Preferred Stock, AMB Property II may
redeem AMB Property II Series C Preferred Units for cash in an amount equal to
the original capital account balance of the holder of AMB Property II Series C
Preferred Units. A

holder of AMB Property II Series C Preferred Units will not be entitled to
exchange the units for Series C Preferred Stock if the exchange would result in
a violation of the ownership limit. See "Description of Capital
Stock -- Restrictions on Ownership and Transfer of Capital Stock."
 
     The Series C Preferred Stock ranks, with respect to dividends and in the
event we voluntarily or involuntarily liquidate, dissolve or wind up:
 
     - senior to all classes or series of common stock and to all of our equity
       securities that provide that they rank junior to the Series C Preferred
       Stock;
 
     - junior to all equity securities issued by us which rank senior to the
       Series C Preferred Stock; and
 
     - on a parity with all equity securities issued by us (including the Series
       A Preferred Stock and the Series B Preferred Stock) other than those
       referred to in the bullet points above. The term "equity securities" does
       not include convertible debt securities until converted into equity
       securities.
 
     If ever issued, the Series C Preferred Stock will entitle the holders to
receive, when and as authorized by the Board of Directors out of funds legally
available for dividends, cumulative preferential cash dividends at the rate of
8.75% of the liquidation preference per annum (equivalent to $4.375 per annum
per share of Series C Preferred Stock). Dividends on the Series C Preferred
Stock accumulate on a daily basis and are payable quarterly in arrears on the
15th day of each January, April, July and October. Except as provided below,
unless full cumulative dividends on the Series C Preferred Stock have been or at
the same time are declared and paid or declared and a sum sufficient for payment
set apart for payment for all past dividend periods and the then current
dividend period, no distributions (other than in common stock or other equity
securities ranking junior to the Series C Preferred Stock) may be declared or
paid or set aside for payment or other dividend be declared or made upon the
common stock or any other equity securities ranking junior to or on a parity
with the Series C Preferred Stock (including the Series A Preferred Stock and
the Series B Preferred Stock), nor may any common stock or any other equity
securities ranking junior to or on a parity with the Series C Preferred Stock
(including the Series A Preferred Stock and the Series B Preferred Stock) be
redeemed, purchased or otherwise acquired for any consideration (or any monies
be paid to or made available for a sinking fund for the redemption of any such
securities) by us (except by conversion into or exchange for other equity
securities ranking junior to the Series C Preferred Stock and pursuant to the
provisions of our Charter providing for limitations on ownership and transfer in
order to ensure that we remain qualified as a REIT). When dividends are not paid
in full (or a sum sufficient for such full payment is not so set apart) upon the
Series C Preferred Stock and any other equity securities ranking on a parity
with the Series C Preferred Stock (including the Series A Preferred Stock and
the Series C Preferred Stock), all dividends declared upon the Series C
Preferred Stock and any other equity securities ranking on a parity with the
Series C Preferred Stock (including the Series A Preferred Stock and the Series
B Preferred Stock) will be declared pro rata so that the amount of dividends
declared per share of Series C Preferred Stock and each such other equity
securities shall bear to each other the same ratio that accumulated dividends
per share of Series C Preferred Stock and such other equity securities (which
shall not include any accumulation in respect of unpaid dividends for prior
dividend periods if such other equity securities do not have a cumulative
dividend) bear to each other. Dividends on the Series C Preferred Stock will
accumulate whether or not we have funds legally available for the payment of
dividends and whether or not we
 
                                       35
<PAGE>   39
 
declare dividends. If we designate any portion of a dividend as a "capital gain
dividend," a holder's share of the capital gain dividend will be an amount that
bears the same ratio to the total amount of dividends (as determined for federal
income tax purposes) paid to the holder for the year as the aggregate amount
designated as a capital gain dividend bears to the aggregate amount of all
dividends (as determined for federal income tax purposes) paid on all classes of
shares for the year.
 
     In the event that we voluntarily or involuntarily liquidate, dissolve or
wind up following the issuance of Series C Preferred Stock, the holders of the
Series C Preferred Stock will be entitled to receive out of our assets legally
available for distribution to our stockholders remaining after payment or
provision for payment of all of our debts and liabilities, a liquidation
preference, in cash, of $50.00 per share, plus an amount equal to any
accumulated or accrued and unpaid dividends to the date of such payment, before
any distribution of assets is made to holders of common stock or any other
equity securities that rank junior to the Series C Preferred Stock. After
payment of the full amount of the liquidating distributions to which they are
entitled, the holders of the Series C Preferred Stock will have no right or
claim to any of our remaining assets. Our consolidation or merger with or into
any other entity, a merger of another entity with or into us, a statutory share
exchange or the sale, lease, transfer or conveyance of all or substantially all
of our property or business do not constitute a liquidation, dissolution or
winding up for purposes of triggering the liquidation preference.
 
     If we voluntarily or involuntarily liquidate, dissolve or wind up following
the issuance of Series C Preferred Stock and our assets are insufficient to make
full payment to holders of the Series C Preferred Stock and the corresponding
amounts payable on all shares of other classes or series of equity securities
ranking on a parity with the Series C Preferred Stock as to liquidation rights
(including the Series A Preferred Stock and the Series B Preferred Stock) then
the holders of the Series C Preferred Stock and all other such classes or series
of equity securities will share ratably in any such distribution of assets in
proportion to the full liquidating distributions to which they would otherwise
be entitled.
 
     The Series C Preferred Stock has no stated maturity and is not subject to
mandatory redemption or any sinking fund. If issued, we cannot redeem the Series
C Preferred Stock prior to November 24, 2003. On and after November 24, 2003, we
can redeem the Series C Preferred Stock for cash at our option, in whole or from
time to time in part, at a redemption price of $50.00 per share, plus
accumulated and unpaid dividends, if any, to the redemption date. We must pay
the redemption price (other than the portion of the redemption price consisting
of accumulated and unpaid dividends) solely out of the sale proceeds of other
equity securities, which may include other classes or series of preferred stock.
In certain circumstances related to our maintenance of our ability to qualify as
a REIT for federal income tax purposes, we may redeem shares of Series C
Preferred Stock. See "-- Restrictions on Ownership and Transfer of Capital
Stock."
 
     Holders of Series C Preferred Stock will have no voting rights, except as
described below. If we do not pay dividends on the Series C Preferred Stock for
six or more quarterly periods (whether or not consecutive), holders of the
Series C Preferred Stock (voting separately as a class with all other classes or
series of equity securities upon which like voting rights have been conferred
and are exercisable) will be entitled to vote for the election of two additional
directors to serve on our Board of Directors until we have eliminated all
dividend arrearages with respect to the Series C Preferred Stock. So long as any
shares of Series C Preferred Stock remain outstanding, we may not, without the
affirmative vote or consent of at least two-thirds of the votes entitled to be
cast by the
 
                                       36
<PAGE>   40
 
holders of the outstanding shares of Series C Preferred Stock (the Series C
Preferred Stock voting separately as a class):
 
     - authorize or create, or increase the authorized or issued amount of, any
       class or series of stock ranking senior to the Series C Preferred Stock;
 
     - reclassify any of our authorized stock into any class or series of stock
       ranking senior to the Series C Preferred Stock;
 
     - designate or create, or increase the authorized or issued amount of, or
       reclassify, any authorized shares into, any preferred stock ranking on a
       parity with the Series C Preferred Stock or create, authorize or issue
       any obligations or securities convertible into any such shares, but only
       to the extent such stock is issued to one of our affiliates; or
 
     - either consolidate, merge into or with, or convey, transfer or lease our
       assets substantially, as an entirety, to any corporation or other entity,
       or amend, alter or repeal the provisions of our Charter, whether by
       merger or consolidation or otherwise, in each case so as to materially
       and adversely affect the powers, special rights, preferences, privileges
       or voting power of the Series C Preferred Stock.
 
     With respect to the occurrence of any of the events set forth in the fourth
bullet point above, so long as we are either the surviving entity and shares of
Series C Preferred Stock remain outstanding with the terms materially unchanged
or the resulting, surviving or transferee entity is a corporation, business
trust or like entity organized under the laws of any state and substitutes for
the Series C Preferred Stock other preferred stock or preferred shares having
substantially the same terms and rights as the Series C Preferred Stock, the
occurrence of any such event will not be considered to materially and adversely
affect rights, preferences, privileges or voting powers of holders of Series C
Preferred Stock. Any increase in the amount of authorized preferred stock, the
creation or issuance of any other class or series of preferred stock or any
increase in an amount of authorized shares of each class or series, in each case
ranking on a parity with or junior to the Series C Preferred Stock will not be
considered to materially and adversely affect such rights, preferences,
privileges or voting powers.
 
     We have agreed to file a registration statement registering the resale of
the shares of Series C Preferred Stock issuable to the holders of AMB Property
II Series C Preferred Units as soon as practicable but not later than 60 days
after the date the AMB Property II Series C Preferred Units are exchanged for
shares of Series C Preferred Stock. We have also agreed to use our best efforts
to cause the registration statement to be declared effective within 120 days
after the date of the exchange.
 
RESTRICTIONS ON OWNERSHIP AND TRANSFER OF CAPITAL STOCK
 
     In order for us to qualify as a REIT under the Code, no more than 50% in
value of all classes of our outstanding shares of capital stock may be owned,
actually or constructively, by five or fewer individuals (as defined in the Code
to include certain entities) during the last half of a taxable year (other than
the first year for which we have made an election to be treated as a REIT). In
addition, if we, or an owner of 10% or more of our capital stock, actually or
constructively own 10% or more of one of our tenants (or a tenant of any
partnership or limited liability company in which we are a partner or member),
the rent received by us (either directly or through the partnership or limited
liability company) from the tenant will not be qualifying income for purposes of
the gross income tests for REITs contained in the Code. A REIT's stock also must
be beneficially
 
                                       37
<PAGE>   41
 
owned by 100 or more persons during at least 335 days of a taxable year of 12
months or during a proportionate part of a shorter taxable year (other than the
first year for which an election to be treated as a REIT has been made).
 
     Because our Board of Directors believes it is desirable for us to qualify
as a REIT, our Charter, subject to certain exceptions as discussed below,
provides that no person may own, or be deemed to own by virtue of the
attribution provisions of the Code, more than 9.8% (by value or number of
shares, whichever is more restrictive) of either our issued and outstanding
common stock or our issued and outstanding Series A Preferred Stock. We will
also prohibit the ownership, actually or constructively, of any shares of our
Series B Preferred Stock and any shares of our Series C Preferred Stock by any
single person so that no such person, taking into account all of our stock so
owned by such person, may own in excess of 9.8% of our issued and outstanding
capital stock. The constructive ownership rules under the Code are complex and
may cause stock owned actually or constructively by a group of related
individuals and/or entities to be owned constructively by one individual or
entity. As a result, the acquisition of less than 9.8% of our common stock,
Series A Preferred Stock or capital stock (or the acquisition of an interest in
an entity that owns, actually or constructively, common stock, Series A
Preferred Stock or capital stock) by an individual or entity, could,
nevertheless cause that individual or entity, or another individual or entity,
to own constructively in excess of 9.8% of our outstanding common stock, Series
A Preferred Stock or capital stock, as the case may be, and thereby subject the
common stock, Series A Preferred Stock, Series B Preferred Stock or Series C
Preferred Stock to the applicable ownership limit. The Board of Directors may,
but in no event will be required to, waive the applicable ownership limit with
respect to a particular stockholder if it determines that such ownership will
not jeopardize our status as a REIT and the Board of Directors otherwise decides
such action would be in our best interest. As a condition of such waiver, the
Board of Directors may require an opinion of counsel satisfactory to it and/or
undertakings or representations from the applicant with respect to preserving
our REIT status. The Board of Directors has waived the ownership limit
applicable to our common stock with respect to Ameritech Pension Trust, allowing
it to own up to 14.9% of our common stock and, under some circumstances,
allowing it to own up to 19.6%. However, we conditioned this waiver upon the
receipt of undertakings and representations from Ameritech Pension Trust which
we believed were reasonably necessary in order for us to conclude that the
waiver would not cause us to fail to qualify as a REIT.
 
     Our Charter also provides that:
 
     - no person may actually or constructively own common stock, Series A
       Preferred Stock, Series B Preferred Stock or Series C Preferred Stock
       that would result in us being "closely held" under Section 856(h) of the
       Code or otherwise cause us to fail to qualify as a REIT;
 
     - no person may transfer common stock, Series A Preferred Stock, Series B
       Preferred Stock or Series C Preferred Stock if a transfer would result in
       shares of our capital stock being owned by fewer than 100 persons; and
 
     - any person who acquires or attempts or intends to acquire actual or
       constructive ownership of common stock, Series A Preferred Stock, Series
       B Preferred Stock or Series C Preferred Stock that will or may violate
       any of the foregoing restrictions on transferability and ownership is
       required to notify us immediately and provide us with such other
       information as we may request in order to determine the effect of the
       transfer on our status as a REIT. The foregoing restrictions on
       transferability
 
                                       38
<PAGE>   42
 
       and ownership will not apply if our Board of Directors determines that it
       is no longer in our best interest to attempt to qualify, or to continue
       to qualify, as a REIT. Except as otherwise described above, any change in
       the applicable ownership limit would require an amendment to our Charter,
       which requires the affirmative vote of holders owning at least two-thirds
       of the shares of our outstanding capital stock entitled to vote on the
       amendment.
 
     Under our Charter, if any attempted transfer of shares of stock or any
other event would otherwise result in any person violating an ownership limit,
any other limit imposed by our Board of Directors or the other restrictions in
the Charter, then any such attempted transfer will be void and of no force or
effect with respect to the purported transferee (the "Prohibited Transferee") as
to that number of shares that exceeds the applicable ownership limit or such
other limit (referred to as "Excess Shares"). Under those circumstances, the
Prohibited Transferee will acquire no right or interest (or, in the case of any
event other than an attempted transfer, the person or entity holding record
title to any shares in excess of the applicable ownership limit (the "Prohibited
Owner") will cease to own any right or interest) in the Excess Shares. Any
Excess Shares described above will be transferred automatically, by operation of
law, to a trust, the beneficiary of which will be a qualified charitable
organization selected by us (the "Beneficiary"). This automatic transfer will be
considered to be effective as of the close of business on the business day prior
to the date of the violating transfer or event. Within 20 days of receiving
notice from us of the transfer of shares to the trust, the trustee of the trust
will be required to sell the Excess Shares to a person or entity who could own
the shares without violating the applicable ownership limit, or any other limit
imposed by our Board of Directors, and distribute to the Prohibited Transferee
an amount equal to the lesser of the price paid by the Prohibited Transferee for
the Excess Shares or the sales proceeds received by the trust for the 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 Excess Shares to a qualified person or entity and
distribute to the Prohibited Owner an amount equal to the lesser of the
applicable market price of the Excess Shares as of the date of the event or the
sales proceeds received by the trust for the Excess Shares. In either case, any
proceeds in excess of the amount distributable to the Prohibited Transferee or
Prohibited Owner will be distributed to the Beneficiary. Prior to a sale of any
Excess Shares by the trust, the trustee will be entitled to receive, in trust
for the Beneficiary, all dividends and other distributions paid by us with
respect to the Excess Shares, and also will be entitled to exercise all voting
rights with respect to the Excess Shares. Subject to Maryland law, effective as
of the date that the shares have been transferred to the trust, the trustee will
have the authority (at the trustee's sole discretion) to rescind as void any
vote cast by a Prohibited Transferee or Prohibited Owner prior to the time that
we discover that the shares have been automatically transferred to the trust and
to recast the vote in accordance with the desires of the trustee acting for the
benefit of the Beneficiary. However, if we have already taken irreversible
corporate action, then the trustee will not have the authority to rescind and
recast the vote. If we pay the Prohibited Transferee or Prohibited Owner any
dividend or other distribution before we discover that the shares were
transferred to the trust, the Purported Transferee or Prohibited Owner will be
required to repay the trustee upon demand for distribution to the Beneficiary.
If the transfer to the trust is not automatically effective (for any reason), to
prevent violation of the applicable ownership limit or any other limit provided
in our Charter or imposed by the Board of Directors, then our Charter provides
that the transfer of the Excess Shares will be void ab initio.
 
                                       39
<PAGE>   43
 
     In addition, shares of stock held in the trust will be considered to have
been offered for sale to us, or our designee, at a price per share equal to the
lesser of (1) the price per share in the transaction that resulted in the
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 (2) the applicable market price on the date
that we, or our designee, accept the offer. We have the right to accept the
offer until the trustee has sold the shares held in the trust. Upon that sale to
us, the interest of the Beneficiary in the shares sold will terminate and the
trustee will distribute the net proceeds of the sale to the Prohibited
Transferee or Prohibited Owner.
 
     If any attempted transfer of shares would cause us to be beneficially owned
by fewer than 100 persons, our Charter provides that the transfer will be null
and void in its entirety and the intended transferee will acquire no rights to
the stock.
 
     All certificates representing shares will bear a legend referring to the
restrictions described above. The ownership limitations described above could
delay, defer or prevent a transaction or a change in control that might involve
a premium price for the shares or otherwise be in the best interest of
stockholders.
 
     Under our Charter, owners of outstanding shares must, upon our demand,
provide us with a completed questionnaire containing information regarding
ownership of the shares, as set forth in the treasury regulations. In addition,
each stockholder must upon demand disclose to us in writing such information
that we may request in order to determine the effect, if any, of the
stockholder's actual and constructive ownership of shares of common stock,
Series A Preferred Stock, Series B Preferred Stock and/or Series C Preferred
Stock on our status as a REIT and to ensure compliance with each ownership
limit, or any other limit specified in the Charter or required by the Board of
Directors.

                    DESCRIPTION OF CERTAIN PROVISIONS OF THE
               PARTNERSHIP AGREEMENT OF THE OPERATING PARTNERSHIP
 
     Substantially all of our assets are held, and all of our operations are
conducted, by or through the Operating Partnership. We are the sole general
partner of the Operating Partnership and owned, as of November 30, 1998, an
approximate 95.1% interest in the Operating Partnership. As the sole general
partner, we have the exclusive right and power to manage the Operating
Partnership. Our interest in the Operating Partnership is designated as a
general partner interest. Except with respect to distributions of cash and
allocations of income and loss, and except as otherwise noted in this
prospectus, the description in this section of common limited partnership Units
is also applicable to Performance Units, and holders of Performance Units will
be treated as limited partners. We have summarized certain terms and provisions
of the Partnership Agreement. This summary is not complete and is qualified by
the provisions of the Partnership Agreement. For more detail, you should refer
to the Partnership Agreement itself, which we have filed as an exhibit to the
registration statement of which this prospectus is a part. See "Where You Can
Find More Information."
 
GENERAL
 
     Holders of limited partnership Units hold limited partnership interests in
the Operating Partnership, and all holders of partnership interests (including
us in our capacity as general partner) are entitled to share in cash
distributions from, and in the profits and losses of, the Operating Partnership.
The number of general partnership Units (the "GP Units") held by us is
approximately equal to the total number of outstanding shares of our common
stock and preferred stock. Accordingly, the distributions that we pay per share
of common stock are expected to be equal to the distributions per unit that the
Operating Partnership pays on the common Units, and the distributions that we
pay per share of Series A Preferred Stock, any Series B Preferred Stock and any
Series C Preferred Stock are expected to be equal to the distributions per unit
that the Operating Partnership pays on the Series A Preferred Units, the Series
B Preferred Units and any Series C Preferred Units, respectively. The Units have
not been registered pursuant to federal or state securities laws, and they will
not be listed on the New York Stock Exchange or any other exchange or quoted on
any national market system. However, the shares of common stock, Series B
Preferred Stock and Series C Preferred Stock that we may issue upon exchange of
the common Units, Series B Preferred Units and AMB Property II Series C
Preferred Units may be sold in registered transactions or transactions exempt
from registration under the Securities Act. The limited partners of the
Operating Partnership have the rights to which limited partners are entitled
under the Partnership Agreement and the Delaware Uniform Limited Partnership Act
(the "Partnership Act"). The Partnership Agreement imposes certain restrictions
on the transfer of Units, as described below.
 
PURPOSE, BUSINESS AND MANAGEMENT
 
     The Operating Partnership is organized as a Delaware limited partnership
pursuant to the terms of the Partnership Agreement. We are the sole general
partner of the Operating Partnership and conduct substantially all of our
business through the Operating Partnership, except for investment advisory
services (which we conduct through AMB Investment Management) and certain other
activities that we conduct through Headlands Realty Corporation.
 
                                       41
<PAGE>   45
 
     The primary purpose of the Operating Partnership is, in general, to
acquire, purchase, own, operate, manage, develop, redevelop, invest in, finance,
refinance, sell, lease and otherwise deal with industrial and retail properties
and assets related to those properties, and interests in those properties and
assets. The Operating Partnership is authorized to conduct any business that a
limited partnership formed under the Partnership Act may lawfully conduct,
except that the Partnership Agreement requires of the Operating Partnership to
conduct its business in such a manner that will permit the Company to be
classified as a REIT under Section 856 of the Code, unless the Company ceases to
qualify as a REIT for reasons other than the conduct of the business of the
Operating Partnership. Subject to the foregoing limitation, the Operating
Partnership may enter into partnerships, joint ventures or similar arrangements
and may own interests directly or indirectly in any other entity.
 
     As the general partner of the Operating Partnership we have the exclusive
power and authority to conduct the business of the Operating Partnership,
subject to the consent of the limited partners in certain limited circumstances
(as discussed below) and except as expressly limited in the Partnership
Agreement.
 
     We have the right to make all decisions and take all actions with respect
to the Operating Partnership's acquisition and operation of our properties and
all other assets and businesses of or related to the Operating Partnership. No
limited partner may take part in the conduct or control of the business or
affairs of the Operating Partnership by virtue of being a holder of Units. In
particular, each limited partner expressly acknowledged in the Partnership
Agreement that as general partner, we are acting on behalf of the Operating
Partnership's limited partners and our stockholders, collectively, and are under
no obligation to consider the tax consequences to limited partners when making
decisions for the benefit of the Operating Partnership. We intend to make
decisions in our capacity as general partner of the Operating Partnership so as
to maximize our profitability and the profitability of the Operating Partnership
as a whole, independent of the tax effects on the limited partners. The Company
and the Operating Partnership have no liability to a limited partner as a result
of any liabilities or damages incurred or suffered by, or benefits not derived
by, a limited partner as a result of an action or inaction of the Company as
general partner of the Operating Partnership as long as the Company acted in
good faith. Limited partners have no right or authority to act for or to bind
the Operating Partnership.
 
     Limited partners of the Operating Partnership have no authority to transact
business for, or participate in the management activities or decisions of, the
Operating Partnership, except as provided in the Partnership Agreement or as
required by applicable law.
 
ENGAGING IN OTHER BUSINESSES; CONFLICTS OF INTEREST
 
     We may not conduct any business other than in connection with the
ownership, acquisition and disposition of Operating Partnership interests as a
general partner and the management of the business of the Operating Partnership,
its operation as a public reporting company with a class (or classes) of
securities registered under the Exchange Act its operation as a REIT and
activities that are incidental to these activities (including ownership of any
interest in AMB Property Holding Corporation, AMB Property Holding II
Corporation, the Preferred Stock Subsidiaries or a title holding, management or
finance subsidiary organized as a partnership, limited liability company or
corporation) without the consent of the holders of a majority of the limited
partnership interests. Unless they otherwise agree in writing, each limited
partner, and its affiliates, is free to engage in any business or activity, even
if the business or activity competes with or is enhanced by
 
                                       42
<PAGE>   46
 
the business of the Operating Partnership. The Partnership Agreement does not
prevent another person or entity that acquires control of the Company in the
future from conducting other businesses or owning other assets, even if it would
be in the best interests of the limited partners for the Operating Partnership
to own those businesses or assets. In the exercise of our power and authority
under the Partnership Agreement, we may contract and otherwise deal with or
otherwise obligate the Operating Partnership to entities in which we or any one
or more of our officers, directors or stockholders may have an ownership or
other financial interest, whether direct or indirect.
 
OUR REIMBURSEMENT; TRANSACTIONS WITH US AND OUR AFFILIATES
 
     We do not receive any compensation for our services as general partner of
the Operating Partnership. However, as a partner in the Operating Partnership,
we have rights to allocations and distributions as a partner of the Operating
Partnership. In addition, the Operating Partnership reimburses us for all
expenses we incur relating to our activities as general partner, our continued
existence and qualification as a REIT and all other liabilities that we incur in
connection with the pursuit of our business and affairs. We may retain persons
or entities that we select (including ourselves, any entity in which we have an
interest, or any entity with which we are affiliated) to provide services to or
on behalf of the Operating Partnership. The Operating Partnership will reimburse
us for all expenses incurred relating to the ongoing operation of the Operating
Partnership and any issuance of additional partnership interests in the
Operating Partnership. These expenses include those incurred in connection with
the administration and activities of the Operating Partnership, such as the
maintenance of the Operating Partnership's books and records, management of the
Operating Partnership's property and assets, and preparation of information
regarding the Operating Partnership provided to the partners in the preparation
of their individual tax returns. Except as expressly permitted by the
Partnership Agreement, however, our affiliates will not engage in any
transactions with the Operating Partnership except on terms that are fair and
reasonable to the Operating Partnership and no less favorable to the Operating
Partnership than it would obtain from an unaffiliated third party.
 
OUR EXCULPATION AND INDEMNIFICATION
 
     The Partnership Agreement generally provides that we, as general partner of
the Operating Partnership, will incur no liability to the Operating Partnership
or any limited partner for losses sustained, liabilities incurred, or benefits
not derived as a result of errors in judgment or for any mistakes of fact or law
or for anything that we may do or not do in connection with the business and
affairs of the Operating Partnership if we carry out our duties in good faith.
Our liability in any event is limited to our interest in the Operating
Partnership. We have no liability for the loss of any limited partner's capital.
In addition, we are not responsible for any misconduct, negligent act or
omission of any of our consultants, contractors or agents, or any of the
Operating Partnership's consultants, contractors or agents, and we have no
obligation other than to use good faith in the selection of all contractors,
consultants and agents. We may consult with counsel, accountants, appraisers,
management consultants, investment bankers, and other consultants and advisors
that we select. An opinion by a consultant on a matter that we believe is within
the consultant's professional or expert competence is considered to be complete
protection as to any action that we take or fail to take based on the opinion
and in good faith.
 
     The Partnership Agreement also requires the Operating Partnership to
indemnify us, our directors and officers, and other persons that we may from
time to time designate
 
                                       43
<PAGE>   47
 
against any loss or damage, including reasonable legal fees and court costs
incurred by the person by reason of anything the person may do or not do for or
on behalf of the Operating Partnership or in connection with its business or
affairs unless it is established that:
 
     - the act or omission of the indemnified person was material to the matter
       giving rise to the proceeding and either the indemnified person committed
       the act or omission in bad faith or as the result of active and
       deliberate dishonesty;
 
     - the indemnified person actually received an improper personal benefit in
       money, property or services; or
 
     - in the case of any criminal proceeding, the indemnified person had
       reasonable cause to believe that the act or omission was unlawful. Any
       indemnification claims must be satisfied solely out of the assets of the
       Operating Partnership.
 
SALES OF ASSETS; LIQUIDATION
 
     Under the Partnership Agreement, as general partner we generally have the
exclusive authority to determine whether, when and on what terms, the Operating
Partnership will sell its assets (including our properties, which we own through
the Operating Partnership). However, we have agreed, in connection with the
contribution of properties from taxable investors in our formation transactions
and certain property acquisitions for Units (with an estimated aggregate value
of approximately $253.7 million), not to dispose of certain assets in a taxable
sale or exchange for a mutually agreed upon period and, thereafter, to use
commercially reasonable or best efforts to minimize the adverse tax consequences
of any sale. We may enter into similar or other agreements in connection with
other acquisitions of properties for Units.
 
     A merger of the Operating Partnership with another entity generally
requires an affirmative vote of the partners (other than the preferred limited
partners) holding a majority of the outstanding percentage interest (including
the interest held directly or indirectly by us) of all partners other than
preferred limited partners, subject to certain consent rights of holders of
Units as described below under "Amendment of the Partnership Agreement." A
dissolution or liquidation of the Operating Partnership, including a sale or
disposition of all or substantially all of the Operating Partnership's assets
and properties, generally requires an affirmative vote of the limited partners
(other than the preferred limited partners) holding a majority of the
outstanding percentage interest of all limited partners other than preferred
limited partners.
 
CAPITAL CONTRIBUTION
 
     The Partnership Agreement provides that if the Operating Partnership
requires additional funds at any time or from time to time in excess of funds
available to the Operating Partnership from borrowings or capital contributions,
we may borrow funds from a financial institution or other lender or through
public or private debt offerings and lend the funds to the Operating Partnership
on the same terms and conditions as are applicable to our borrowing of the
funds. As an alternative to borrowing funds required by the Operating
Partnership, we may contribute the amount of the required funds as an additional
capital contribution to the Operating Partnership. If we contribute additional
capital to the Operating Partnership, our partnership interest in the Operating
Partnership will be increased on a proportionate basis. Conversely, the
partnership interests of the limited partners will be decreased on a
proportionate basis if we make additional capital contributions.
                                       44
<PAGE>   48
 
DISTRIBUTIONS; ALLOCATIONS OF INCOME AND LOSS
 
     The Partnership Agreement generally provides that the Operating Partnership
will make quarterly distributions of Available Cash (as defined below), as
determined in the manner provided in the Partnership Agreement, to the partners
of the Operating Partnership in proportion to their percentage interests in the
Operating Partnership (which for any partner is determined by the number of
Units it owns relative to the total number of Units outstanding). If any
preferred Units are outstanding, the Operating Partnership will pay
distributions to holders of preferred Units in accordance with the rights of
each class of preferred Units (and, within each such class, pro rata in
proportion to the respective percentage interest of each holder), with any
remaining Available Cash distributed in accordance with the previous sentence.
"Available Cash" is generally defined as net cash flow from operations, plus any
reduction in reserves, and minus interest and principal payments on debt,
capital expenditures, any additions to reserves and other adjustments. Other
than as described below, neither we nor the limited partners are currently
entitled to any preferential or disproportionate distributions of Available Cash
with respect to the Units.
 
SERIES A PREFERRED UNITS
 
     In connection with the sale of the Series A Preferred Shares, we received
Series A Preferred Units in the Operating Partnership that mirror the rights,
preferences and other terms of the Series A Preferred Stock. The Series A
Preferred Units rank, with respect to distribution rights and rights upon
liquidation, winding up or dissolution of the Operating Partnership:
 
     - senior to the common Units and to all Units that provide that they rank
       junior to the Series A Preferred Units;
 
     - junior to all Units which rank senior to the Series A Preferred Units;
       and
 
     - on a parity with the Series B Preferred Units, any Series C Preferred
       Units that the Operating Partnership may issue to us (see "-- Series C
       Preferred Units") and all other Units expressly designated by the
       Operating Partnership to rank on a parity with the Series A Preferred
       Units.
 
     We receive preferred distributions of cash and preferred allocations of
income on the Series A Preferred Units in an amount equal to the dividends
payable by us on the Series A Preferred Stock. If we acquire any Series B
Preferred Units from the holders pursuant to the exercise of their exchange
rights, or if the Operating Partnership issues any Series C Preferred Units to
us, we will receive preferred distributions of cash and preferred allocations of
income on the Series B Preferred Units or Series C Preferred Units in an amount
equal to the dividends payable by us on the Series B Preferred Stock or Series C
Preferred Stock. See "-- Series C Preferred Units."
 
     As a consequence, we will receive distributions from the Operating
Partnership sufficient to pay dividends on the Series A Preferred Stock and any
Series B Preferred Stock and Series C Preferred Stock before any other partner
in the Operating Partnership (other than holders of parity preferred units,
including the Series B Preferred Units) receives a distribution. In addition, if
necessary, income will be specially allocated to us and losses will be allocated
to the other partners of the Operating Partnership in amounts necessary to
ensure that, to the extent possible, the balance in our capital account will at
all times be equal to or in excess of the amount payable by us on the Series A
Preferred Stock and any Series B Preferred Stock and Series C Preferred Stock
upon liquidation or
 
                                       45
<PAGE>   49
 
redemption. See "Certain Federal Income Tax Considerations -- Tax Aspects of the
Operating Partnership and the Joint Ventures -- Allocations of Operating
Partnership Income, Gain, Loss and Deduction."
 
SERIES B PREFERRED UNITS
 
     General. The Series B Preferred Units rank, with respect to distribution
rights and rights upon liquidation, winding up or dissolution of the Operating
Partnership:
 
     - senior to the common Units and to all Units that provide that they rank
       junior to the Series B Preferred Units;
 
     - junior to all Units which rank senior to the Series B Preferred Units;
       and
 
     - on a parity with the Series A Preferred Units, any Series C Preferred
       Units and all other Units expressly designated by the Operating
       Partnership to rank on a parity with the Series B Preferred Units.
 
     Subject to the rights of holders of parity preferred Units (including the
Series A Preferred Units and any Series C Preferred Units), holders of the
Series B Preferred Units are entitled to receive, when, as and if declared by
the Operating Partnership, acting through us as general partner, cumulative
preferential cash distributions in an amount equal to 8 5/8% per annum on an
amount equal to $50.00 per Series B Preferred Unit then outstanding (equivalent
to $4.3125 per annum). These distributions are payable on the 15th day of
January, April, July and October of each year.
 
     Exchange Rights. The Series B Preferred Units are exchangeable in whole at
any time on or after November 12, 2008, at the option of 51% of the holders of
all outstanding Series B Preferred Units, on a one for one basis, subject to
adjustment, for shares of our Series B Preferred Stock. In addition, the Series
B Preferred Units are exchangeable in whole at any time at the option of 51% of
the holders of all outstanding Series B Preferred Units if:
 
     - any Series B Preferred Unit shall not have received full distributions
       with respect to six prior quarterly distribution periods (whether or not
       consecutive); or
 
     - we or one of our subsidiaries take the position, and a holder or holders
       of Series B Preferred Units receive an opinion of independent counsel
       that the Operating Partnership is, or upon the happening of a certain
       event likely will be, a "publicly traded partnership" within the meaning
       of the Code.
 
     The Series B Preferred Units are exchangeable in whole for shares of Series
B Preferred Stock at any time after November 12, 2001 and prior to November 12,
2008 at the option of 51% of the holders of all outstanding Series B Preferred
Units if those holders deliver to us as general partner a private letter ruling
or an opinion of independent counsel to the effect that an exchange of the
Series B Preferred Units at that time would not cause the Series B Preferred
Units to be considered "stock and securities" within the meaning of the Code for
purposes of determining whether the holder of Series B Preferred Units is an
"investment company" under the Code.
 
     With certain limitations, the Series B Preferred Units are also
exchangeable in whole at any time for shares of Series B Preferred Stock
(regardless of whether held by the initial purchaser) if:
 
     - the initial purchaser of the Series B Preferred Units reasonably
       concludes that there exists an imminent and substantial risk that the
       initial purchaser's interest in the
 
                                       46
<PAGE>   50
 
       Operating Partnership represents or will represent more than 19.5% of the
       total profits or capital interests in the Operating Partnership for a
       taxable year;
 
     - the initial purchaser of the Series B Preferred Units delivers to us an
       opinion to the effect that there is a substantial risk that the initial
       purchaser's interest in the Operating Partnership represents or will
       represent more than 19.5% of the total profits or capital interests in
       the Operating Partnership for a taxable year; and
 
     - we, as the general partner, agree with the conclusions in the bullet
       points above; provided, that we may not unreasonably withhold our
       agreement.
 
     In lieu of an exchange for Series B Preferred Stock, we may elect to cause
the Operating Partnership to redeem Series B Preferred Units for cash in an
amount equal to the original capital account balance of the Series B Preferred
Units plus all accrued and unpaid distributions to the date of redemption. A
holder of Series B Preferred Units will not be entitled to exchange the Units
for Series B Preferred Stock if the exchange would result in a violation of the
ownership limit. See "Description of Capital Stock -- Restrictions on Ownership
and Transfer of Capital Stock."
 
     Redemption. On or after November 12, 2003, the Operating Partnership has
the right to redeem the Series B Preferred Units, in whole or in part from time
to time, at a redemption price payable in cash equal to the capital account
balance of the holder, provided that the amount shall not be less than $50.00
per Series B Preferred Unit. The Operating Partnership must pay the redemption
price solely out of the sale proceeds of our capital stock or interests in the
Operating Partnership and from no other source. The Operating Partnership may
not redeem fewer than all of the Series B Preferred Units unless the Operating
Partnership has paid all accumulated and unpaid distributions on all Series B
Preferred Units for all quarterly distribution periods terminating on or prior
to the date of redemption.
 
     Limited Approval Rights. For so long as any Series B Preferred Units are
outstanding, without the affirmative vote of the holders of at least two-thirds
of the Series B Preferred Units outstanding at the time, the Operating
Partnership may not:
 
     - authorize, create or increase the authorized or issued amount of, or
       reclassify, any class or series of partnership interests, or create,
       authorize or issue any obligations or security convertible into or
       evidencing the right to purchase any partnership interests, ranking prior
       to the Series B Preferred Units;
 
     - authorize, create or increase the authorized or issued amount of, or
       reclassify, any class or series of partnership interests, or create,
       authorize or issue any obligations or security convertible into or
       evidencing a right to purchase any partnership interests, ranking equal
       to the Series B Preferred Units, but only to the extent that such
       securities are issued to an affiliate of the Operating Partnership, other
       than us to the extent that the issuance is to allow us to issue
       corresponding shares of Series B Preferred Stock to persons who are not
       affiliates of the Operating Partnership; or
 
     - either consolidate, merge into or with, or convey, transfer or lease its
       assets substantially as an entirety to, any corporation or other entity
       or amend, alter or repeal the provisions of the Partnership Agreement, in
       a manner that would materially and adversely affect the powers, special
       rights, preferences, privileges or voting power of the Series B Preferred
       Units. So long as the Operating Partnership is the surviving entity and
       the Series B Preferred Units remain outstanding on the
 
                                       47
<PAGE>   51
 
       same terms, or the resulting, surviving or transferee entity is a
       partnership, limited liability company or other pass-through entity and
       substitutes the Series B Preferred Units for other interests in such
       entity, with substantially the same terms and rights, then the occurrence
       of any of the events listed above in this bullet point will not be
       considered to materially and adversely affect such rights, privileges or
       voting powers.
 
     Other than as discussed above or elsewhere in this prospectus, the holders
of Series B Preferred Units have no voting rights other than with respect to
certain matters that would adversely affect them or as otherwise provided by
applicable law.
 
     Liquidation Preference. The distribution and income allocation provisions
of the Partnership Agreement have the effect of providing each Series B
Preferred Unit with a liquidation preference to each holder of such Units equal
to the holder's capital contributions, plus any accrued but unpaid
distributions, in preference to any other class or series of partnership
interest of the Operating Partnership, other than any Series A Preferred Units
and any Series C Preferred Units.
 
     Registration Rights. We have agreed to file a registration statement
registering the resale of the shares of Series B Preferred Stock issuable to the
holders of Series B Preferred Units as soon as practicable but not later than 60
days after the date the Series B Preferred Units are exchanged for shares of
Series B Preferred Stock. We have also agreed to use our best efforts to cause
the registration statement to be declared effective within 120 days after the
date of the exchange.
 
SERIES C PREFERRED UNITS
 
     As described under "Description of Capital Stock -- Preferred
Stock -- Series C Preferred Stock," holders of AMB Property II Series C
Preferred Units may exchange their units for shares of our Series C Preferred
Stock. If we issue Series C Preferred Stock, we will:
 
     - contribute 99% of the AMB Property II Series C Preferred Units to the
       Operating Partnership in exchange for Series C Preferred Units in the
       Operating Partnership that mirror the rights, preferences and other terms
       of the Series C Preferred Stock; and
 
     - contribute 1% of the AMB Property II Series C Preferred Units to AMB
       Property Holding Corporation.
 
     Any Series C Preferred Units will rank on a parity with the Series A
Preferred Units and Series B Preferred Units. As a consequence, we would receive
distributions from the Operating Partnership that we would use to pay dividends
on any Series C Preferred Stock and the Series A Preferred Stock before any
other partner in the Operating Partnership (other than holders of parity
preferred units, including the Series B Preferred Units).
 
COMMON LIMITED PARTNERSHIP UNITS
 
  Redemption/Exchange Rights
 
     Holders of common Units have the right, commencing generally on or before
the first anniversary of the holder becoming a limited partner of the Operating
Partnership (or such other date agreed to by the Operating Partnership and the
applicable Unit holders), to require the Operating Partnership to redeem part or
all of their common Units for cash (based upon the fair market value of an
equivalent number of shares of common stock at the time of redemption) or we
may, in our sole and absolute discretion (subject to the
 
                                       48
<PAGE>   52
 
limits on ownership and transfer of common stock set forth in our Charter) elect
to exchange those common Units for shares of common stock (on a one-for-one
basis, subject to adjustment in the event of stock splits, stock dividends,
issuance of certain rights, certain extraordinary distributions and similar
events). See "Redemption/Exchange of Common Units for Common Stock." We
presently anticipate that we will elect to issue shares of common stock in
exchange for common Units in connection with each redemption request, rather
than having the Operating Partnership pay cash. With each redemption or
exchange, our percentage ownership interest in the Operating Partnership will
increase. Common limited partners may exercise this redemption/exchange right
from time to time, in whole or in part, subject to the limitations that limited
partners may not exercise the right if exercise would result in any person
actually or constructively owning shares of common stock in excess of the
ownership limit or any other amount specified by the Board of Directors,
assuming common stock was issued in the exchange. Holders of Performance Units
also have limited redemption/exchange rights, as discussed under the caption
"-- Performance Units" below.
 
  Registration Rights
 
     We have granted to common limited partners certain registration rights with
respect to the shares of stock issuable upon exchange of common Units or
otherwise. We have agreed to file and generally keep continuously effective
generally beginning on or as soon as practicable after one year after issuance
of common Units a registration statement covering the issuance of shares of
common stock upon exchange of the Units and the resale of the shares.
 
     This prospectus is a part of the registration statement registering the
shares issuable to limited partners of the Operating Partnership who hold common
Units issued on November 26, 1997 in connection with our formation. Pursuant to
the terms and conditions of such registration rights, prior to the date upon
which the shares of common stock issuable upon exchange of the common Units
would be eligible for resale under Rule 144(k) under the Securities Act, as such
rule may be amended from time to time (or any similar rule or regulation
hereafter adopted by the SEC), each of the selling stockholders generally is
limited to resales of shares of common stock issued pursuant to this prospectus
to the number of shares which otherwise would be eligible for resale by that
selling stockholder pursuant to Rule 144, assuming the shares were issued on the
same date as the respective common Units were issued. In addition, we have
agreed to file a registration statement covering shares of common stock issuable
upon exchange of Performance Units. We may also agree to provide registration
rights to any other person who may become an owner of Units, provided the person
provides us with satisfactory undertakings. See "Risk Factors -- Ownership of
Common Stock -- The Large Number of Shares Available for Future Sale Could
Adversely Affect the Market Price of Our Common Stock." We will bear expenses
incident to our registration obligations upon exercise of registration rights,
including the payment of federal securities law and state Blue Sky registration
fees, except that we will not bear any underwriting discounts or commissions or
transfer taxes relating to registration of the shares.
 
PERFORMANCE UNITS
 
     Notwithstanding the foregoing discussion of distributions and allocations
of income or loss of the Operating Partnership, depending on the trading price
of our common stock after November 26, 1998 (the first anniversary of our
initial public offering), certain of our officers, in their capacity as limited
partners of the Operating Partnership, may receive
 
                                       49
<PAGE>   53
 
performance units ("Performance Units") as of each of February 26, May 26,
August 26 and November 26, 1999. The Performance Units are similar to common
Units in many respects, including the right to share in operating distributions,
and allocations of operating income and loss, of the Operating Partnership on a
pro rata basis with common Units, and certain redemption and exchange rights,
including limited rights to cause the Operating Partnership to redeem the
Performance Units for cash or, at the Company's option, to exchange the
Performance Units for shares of common stock. Any redemption rights with respect
to Performance Units, however, will be dependent upon an increase in the value
of the assets of the Operating Partnership (in some cases measured by reference
to the trading price of the shares of common stock) after the issuance of the
Performance Units. If there is no increase, the holders of Performance Units
will not be entitled to receive any proceeds upon the liquidation of the
Operating Partnership or the redemption of their Performance Units.
 
     Immediately prior to our initial public offering, certain investors owned
assets that were subject to advisory agreements with AMB Institutional Realty
Advisors, Inc. containing an incentive fee provision or a "catch up adjustment."
We refer to these investors as "Performance Investors." Allmerica Financial Life
Insurance and Annuity Company, which is a selling stockholder under this
registration statement, is a Performance Investor. If officers receive
Performance Units, an equal number of GP Units allocable to the Company and
Units allocable to Performance Investors who are limited partners in the
Operating Partnership will be transferred to the Operating Partnership. 55,963
of Allmerica's Units are held in an escrow account for possible transfer to the
Operating Partnership. If any of our GP Units are transferred to the Operating
Partnership as a result of the issuance of Performance Units, an equal number of
shares of common stock (the "Performance Shares") will be transferred to us by
the applicable Performance Investors. Accordingly, no Company stockholder or
limited partner in the Operating Partnership (other than Performance Investors,
to the extent of their obligations to transfer Performance Shares to the Company
or the Operating Partnership, as applicable) will be diluted as a result of the
issuance of Performance Units.
 
REMOVAL OF THE GENERAL PARTNER; TRANSFERABILITY OF OUR INTERESTS; TREATMENT OF
LIMITED PARTNERSHIP UNITS IN SIGNIFICANT TRANSACTIONS
 
     The limited partners may not remove us as general partner, with or without
cause, other than with our consent. The Partnership Agreement provides that we
may not withdraw from the Operating Partnership (whether by sale, statutory
merger, consolidation, liquidation or otherwise) without the consent of a
majority in interest of the limited partners other than the preferred limited
partners. However, except as set forth below, we may transfer or assign our
general partner interest in connection with a merger, consolidation or sale of
substantially all of our assets without limited partner consent.
 
     Neither the Company nor the Operating Partnership may engage in any merger,
consolidation or other combination with or into another person, or effect any
reclassification, recapitalization or change of its outstanding equity
interests, and the Company may not sell all or substantially all of its assets
(each a "Termination Transaction") unless in connection with the Termination
Transaction all holders of limited partnership Units other than preferred Units
either will receive, or will have the right to elect to receive, for each Unit
an amount of cash, securities or other property equal to the product of the
number of shares of common stock into which each Unit is then exchangeable and
the greatest amount of cash, securities or other property paid to the holder of
one share in consideration of one share pursuant to the Termination Transaction.
 
                                       50
<PAGE>   54
 
If, in connection with the Termination Transaction, a purchase, tender or
exchange offer shall have been made to and accepted by the holders of the
outstanding shares of common stock, each holder of limited partnership Units
other than preferred Units will receive, or will have the right to elect to
receive, the greatest amount of cash, securities or other property that the
holder would have received had it exercised its right to redemption and received
shares of common stock in exchange for its Units immediately prior to the
expiration of the purchase, tender or exchange offer and had accepted the
purchase, tender or exchange offer. Any Performance Units issued will also have
the benefit of these provisions, irrespective of the capital account then
applicable to the Performance Units.
 
     A Termination Transaction may also occur if the following conditions are
met:
 
     - substantially all of the assets directly or indirectly owned by the
       surviving entity are held directly or indirectly by the Operating
       Partnership or another limited partnership or limited liability company
       which is the survivor of a merger, consolidation or combination of assets
       with the Operating Partnership;
 
     - the holders of common Units, including the holders of any Performance
       Units issued, own a percentage interest of the surviving partnership
       based on the relative fair market value of the net assets of the
       Operating Partnership and the other net assets of the surviving
       partnership immediately prior to the consummation of the transaction;
 
     - the rights, preferences and privileges of the holders in the surviving
       partnership, including the holders of Performance Units issued or to be
       issued, are at least as favorable as those in effect immediately prior to
       the consummation of such transaction and as those applicable to any other
       limited partners or non-managing members of the surviving partnership
       (except, as to Performance Units, for such differences with Units
       regarding liquidation, redemption or exchange as are described in this
       prospectus); and
 
     - such rights of the common limited partners, including the holders of
       Performance Units issued or to be issued, include at least one of the
       following:
 
        - the right to redeem their interests in the surviving partnership for
          the consideration available to them pursuant to the preceding
          paragraph; or
 
        - the right to redeem their Units for cash on terms equivalent to those
          in effect immediately prior to the consummation of the transaction,
          or, if the ultimate controlling person of the surviving partnership
          has publicly traded common equity securities, the common equity
          securities, with an exchange ratio based on the relative fair market
          value of the securities and the common stock.
 
     Our Board of Directors will reasonably determine fair market values and
rights, preferences and privileges of the common limited partners as of the time
of the Termination Transaction and, to the extent applicable, the values will be
no less favorable to the holders of common Units than the relative values
reflected in the terms of the Termination Transaction.
 
     In addition, in the event of a Termination Transaction, the arrangements
with respect to Performance Units and Performance Shares (as defined under
"-- Performance Units") will be equitably adjusted to reflect the terms of the
transaction, including, to the extent that the shares are exchanged for
consideration other than publicly traded common equity, the transfer or release
of remaining Performance Shares, and resulting issuance of any Performance
Units, as of the consummation of the Termination Transaction.
 
                                       51
<PAGE>   55
 
DUTIES AND CONFLICTS
 
     Except as otherwise provided by our conflicts of interest policies with
respect to directors and officers and as provided in the non-competition
agreements described under "Risk Factors -- Conflicts of Interest -- Some of Our
Executive Officers are Involved in Other Real Estate Activities and
Investments," any limited partner of the Operating Partnership may engage in
other business activities outside the Operating Partnership, including business
activities that directly compete with the Operating Partnership.
 
MEETINGS; VOTING
 
     As general partner, we may call meetings of the limited partners of the
Operating Partnership, on our own motion, or upon written request of limited
partners owning at least 25% of the then outstanding Units. Limited partners may
vote either in person or by proxy at meetings. Limited partners may take any
action that they are required or permitted to take either at a meeting of the
limited partners or without a meeting if consents in writing setting forth the
action taken are signed by limited partners owning not less than the minimum
number of Units that would be necessary to authorize or take the action at a
meeting of the limited partners at which all limited partners entitled to vote
on the action were present. On matters for which limited partners are entitled
to vote, each limited partner has a vote equal to the number of Units the
limited partner holds. A transferee of Units who has not been admitted as a
substituted limited partner with respect to the Units will have no voting rights
with respect to the Units, even if the transferee holds other Units as to which
it has been admitted as a limited partner. The Partnership Agreement does not
provide for, and we do not anticipate calling, annual meetings of the limited
partners.
 
AMENDMENT OF THE PARTNERSHIP AGREEMENT
 
     Amendments to the Partnership Agreement may be proposed by the Company or
by limited partners owning at least 25% of the then outstanding Units entitled
to vote. Generally, the Partnership Agreement may be amended with our approval,
as general partner, and partners (including us but not including the preferred
limited partners) holding a majority of the percentage interest of all partners
other than preferred limited partners. Certain provisions regarding, among other
things, our rights and duties as general partner (e.g., restrictions on our
power to conduct businesses other than as denoted herein) or the dissolution of
the Operating Partnership, may not be amended without the approval of limited
partners (other than preferred limited partners) holding a majority of the
percentage interests of the limited partners other than preferred limited
partners. As general partner, we have the power, without the consent of the
limited partners, to amend the Partnership Agreement as may be required to,
among other things:
 
     - add to our obligations as general partner or surrender any right or power
       granted to us as general partner;
 
     - reflect the admission, substitution, termination or withdrawal of
       partners in accordance with the terms of the Partnership Agreement;
 
     - establish the rights, powers, duties and preferences of any additional
       partnership interests issued in accordance with the terms of the
       Partnership Agreement;
 
     - reflect a change of an inconsequential nature that does not materially
       adversely affect any limited partner, or cure any ambiguity, correct or
       supplement any provisions of the Partnership Agreement not inconsistent
       with law or with other
 
                                       52
<PAGE>   56
 
       provisions of the Partnership Agreement, or make other changes concerning
       matters under the Partnership Agreement that are not otherwise
       inconsistent with the Partnership Agreement or applicable law; or
 
     - satisfy any requirements of federal, state or local law.
 
     We must approve, and each limited partner that would be adversely affected
must approve, certain amendments to the Partnership Agreement, including
amendments effected directly or indirectly through a merger or sale of assets of
the Operating Partnership or otherwise, that would, among other things,
 
     - convert a limited partner's interest into a general partner's interest;
 
     - modify the limited liability of a limited partner;
 
     - alter the interest of a partner in profits or losses, or the rights to
       receive any distributions (except as permitted under the Partnership
       Agreement with respect to the admission of new partners or the issuance
       of additional Units, either of which actions will have the effect of
       changing the percentage interests of the partners and thereby altering
       their interests in profits, losses and distributions); or
 
     - alter the limited partner's redemption right.
 
     These protections apply to both holders of common Units and holders of
Performance Units. In addition, no amendment may be effected, directly or
indirectly, through a merger or sale of assets of the Operating Partnership or
otherwise, which would adversely affect the rights of former stockholders of AMB
Institutional Realty Advisors to receive Performance Units.
 
BOOKS AND REPORTS
 
     The Operating Partnership's books and records are maintained at the
principal office of the Operating Partnership, which is located at 505
Montgomery Street, San Francisco, California 94111. All elections and options
available to the Operating Partnership for federal or state income tax purposes
may be taken or rejected by the Operating Partnership in our sole discretion as
general partner. The limited partners have the right, subject to certain
limitations, to receive copies of the most recent SEC filings by us and the
Operating Partnership, the Operating Partnership's federal, state and local
income tax returns, a list of limited partners, the Partnership Agreement, the
partnership certificate and all amendments and certain information about the
capital contributions of the partners. We may keep confidential from the limited
partners any information that we believe to be in the nature of trade secrets or
other information the disclosure of which the we in good faith believe is not in
the best interests of the Operating Partnership or which the Operating
Partnership is required by law or by agreements with unaffiliated third parties
to keep confidential.
 
     We will use reasonable efforts to furnish to each limited partner, within
90 days after the close of each taxable year, the tax information reasonably
required by the limited partners for federal and state income tax reporting
purposes.
 
TERM
 
     The Operating Partnership will continue in full force and effect for
approximately 99 years or until sooner dissolved pursuant to the terms of the
Partnership Agreement.

              REDEMPTION/EXCHANGE OF COMMON UNITS FOR COMMON STOCK
 
TERMS OF THE EXCHANGE
 
     Beginning on November 26, 1998, the limited partners of the Operating
Partnership who hold common Units issued on November 26, 1997 (the selling
stockholders under this prospectus) may require the Operating Partnership to
redeem up to 2,542,163 of their common Units for cash by delivering to the
Company, as general partner of the Operating Partnership, a notice of
redemption. Upon receipt of the notice of redemption, the Company may, in its
sole and absolute discretion (subject to the limitations on ownership and
transfer of common stock set forth in the Charter), elect to exchange those
common Units for shares of common stock on a one-for-one basis, subject to
adjustment as described under "Description of Certain Provisions of the
Partnership Agreement of the Operating Partnership -- Common Limited Partnership
Units -- Redemption/Exchange Rights."
 
     A tendering partner will have the right to receive, on the day of receipt
by the Company of a notice of redemption, the number of shares of common stock
which corresponds to the number of common Units that the Company has elected to
exchange in lieu of a cash redemption. Any shares of common stock issued by the
Company to a limited partner will be duly authorized, validly issued, fully paid
and nonassessable shares, free of any pledge, lien, encumbrance or restriction
other than those provided in the Charter, the Bylaws, the Securities Act,
relevant state securities or blue sky laws and any applicable registration
rights agreement with respect to the shares entered into by the tendering
partner. Notwithstanding any delay in delivery, the tendering partner will be
considered to be owner of shares and rights for all purposes, including rights
to vote or consent and receive dividends as of the date the Company received the
notice of redemption.
 
     Each tendering partner will continue to own all Units subject to any
redemption or exchange, and be treated as a limited partner with respect to the
Units for all purposes, until the limited partner transfers the Units to us and
we pay for them or exchange them, and until that time, the partner will have no
rights as a stockholder.
 
CERTAIN CONDITIONS TO THE EXCHANGE
 
     The consummation of a redemption or exchange as described above upon the
Company's receipt of a notice of redemption from a tendering partner is subject
to the following conditions:
 
     - in order to protect the Company's status as a REIT, no tendering partner
       will be entitled to effect a redemption for cash or an exchange for
       common stock, if the ownership or right to acquire common stock would
       cause the tendering partner or any other person to violate the ownership
       limit;
 
     - without the consent of the Company, no tendering partner may effect a
       redemption for less than 10,000 Units, or if the tendering partner holds
       less than 10,000 Units, all of the Units held by the tendering partner;
 
     - without the consent of the Company, no tendering partner may effect a
       redemption during the period after the record date established by the
       Company for a distribution from the Operating Partnership to the partners
       in the Operating Partnership and before the record date established by
       the Company for a
 
                                       54
<PAGE>   58
 
       distribution to its common stockholders of some or all of its portion of
       such distribution; and
 
     - the consummation of any redemption or exchange will be subject to the
       expiration or termination of any waiting period under the
       Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.
 
COMPARISON OF OWNERSHIP OF COMMON UNITS AND COMMON STOCK
 
     Generally, the nature of an investment in common stock of the Company is
similar in several respects to an investment in common Units of the Operating
Partnership. Holders of common stock and holders of common Units generally
receive the same distributions and stockholders and holders of common Units
generally share in the risks and rewards of ownership in the enterprise being
conducted by the Company through the Operating Partnership. However, there are
also differences between ownership of common Units and ownership of common
stock, some of which may be material to investors.
 
     The information below highlights a number of the significant differences
between the Operating Partnership and the Company relating to, among other
things, form of organization, management control, voting rights, liquidity and
federal income tax considerations. These comparisons are intended to assist
limited partners in understanding how their investment will be changed if they
exchange their common Units for shares of common stock in the Company. THIS
DISCUSSION IS SUMMARY IN NATURE AND DOES NOT CONSTITUTE A COMPLETE DISCUSSION OF
THESE MATTERS, AND HOLDERS OF UNITS SHOULD CAREFULLY REVIEW THE REST OF THIS
PROSPECTUS AND THE REGISTRATION STATEMENT OF WHICH THIS PROSPECTUS IS A PART FOR
ADDITIONAL IMPORTANT INFORMATION ABOUT THE COMPANY.

                     FORM OF ORGANIZATION AND ASSETS OWNED
 
OPERATING PARTNERSHIP

The Operating Partnership is organized as a Delaware limited partnership. The
Operating Partnership owns substantially all of the Company's assets and
conducts substantially all of the Company's business. The Operating
Partnership's purpose is to conduct any business that may be lawfully conducted
by a limited partnership organized pursuant to the Delaware Revised Uniform
Limited Partnership Act, provided that the Operating Partnership must conduct
its business in a manner that permits the Company to be qualified as a REIT
unless the Company ceases to qualify as REIT for reasons other than the conduct
of the business of the Operating Partnership.
 
COMPANY

The Company is a Maryland corporation. The Company has elected to be taxed as a
REIT under the Code, commencing with its taxable year ending December 31, 1997,
and intends to maintain its qualification as a REIT. The Company's only
substantial asset is its interest in the Operating Partnership, which gives the
Company an indirect investment in the properties owned by the Operating
Partnership. Under its Charter, the Company may engage in any lawful activity
permitted by the MGCL.
 
                               ADDITIONAL EQUITY
 
OPERATING PARTNERSHIP

The Operating Partnership is authorized to issue Units and other partnership
interests (including partnership interests of different series or classes that
may be senior to common Units) as determined by the Company as its general
partner, in its sole discretion. The Operating Partnership may issue Units and
other partnership interests to the Company, as long as the Operating Partnership
issues such interests in connection with a comparable issuance of shares of the
Company and the Company contributes to the Operating Partnership proceeds raised
in connection with the issuance of such shares.
 
COMPANY

The Board of Directors may issue, in its discretion, additional shares of common
stock or additional shares of preferred stock; provided, that the total number
of shares issued does not exceed the authorized number of shares of capital
stock set forth in the Company's Charter. As long as the Operating Partnership
is in existence, the Company will contribute to the Operating Partnership the
proceeds of all equity capital raised by the Company in exchange for Units in
the Operating Partnership.

                               MANAGEMENT CONTROL
 
OPERATING PARTNERSHIP

All management powers over the business and affairs of the Operating Partnership
are exclusively vested in the Company as the general partner, and no limited
partner of the Operating Partnership has any right to participate in or exercise
control or management power over the business and affairs of the Operating
Partnership except as provided below under "-- Voting Rights." The general
partner may not be removed by the limited partners with or without cause.
 
COMPANY

The Board of Directors has exclusive control over the Company's business affairs
subject only to the restrictions in the Charter and Bylaws. At each annual
meeting of stockholders, the Company's stockholders elect the Company's
directors for one year terms. The Board of Directors may alter or eliminate its
policies without a vote of the stockholders. Accordingly, except for their vote
in the election of directors, stockholders have no control over the ordinary
business policies of the Company. The Company cannot change its policy of
maintaining its status as a REIT, however, without the approval of holders of
two-thirds of the shares of the Company's capital stock outstanding and entitled
to vote on the change.

                                FIDUCIARY DUTIES
 
OPERATING PARTNERSHIP

Under Delaware law, the general partner of the Operating Partnership is
accountable to the Operating Partnership as a fiduciary and, consequently, is
required to exercise good faith and integrity in all of its dealings with
respect to partnership affairs. However, under the Partnership Agreement, the
general partner is not liable for monetary damages for losses sustained,
liabilities incurred or benefits not derived by partners as a result of errors
of judgment or mistakes of fact or law or any act or omission, provided that the
general partner has acted in good faith. Each limited partner expressly
acknowledged in the Partnership Agreement that as general partner, the Company
is acting on behalf of the Operating Partnership's limited partners and the
Company's stockholders, collectively, and is under no obligation to consider the
tax consequences to limited partners when making decisions for the benefit of
the Operating Partnership. The Company intends to make decisions in its capacity
as general partner of the Operating Partnership so as to maximize its
profitability and the profitability of the Operating Partnership as a whole,
independent of the tax effects on the limited partners.
 
COMPANY

Under Maryland law, the directors must perform their duties in good faith, in a
manner that they reasonably believe to be in the best interests of the Company
and with the care of an ordinarily prudent person in a like position. Directors
of the Company who act in such a manner generally will not be liable to the
Company for monetary damages arising from their activities.

                                 VOTING RIGHTS
 
OPERATING PARTNERSHIP

Under the Partnership Agreement, the common limited partners have voting rights
only as to the dissolution of the Operating Partnership, the sale of all or
substantially all of the Operating Partnership's assets or merger of the
Operating Partnership, and amendments of the Partnership Agreement, as described
more fully below. Otherwise, all decisions relating to the operation and
management of the Operating Partnership are made by the general partner. As of
November 30, 1998, the Company owned an approximate 95.1% general partner
interest in the Operating Partnership. As Units are redeemed or exchanged by
limited partners, the Company's percentage ownership of the Units will increase.
If additional Units are issued to third parties, the Company's percentage
ownership of the Units will decrease.
 
COMPANY

The Company is managed and controlled by a Board of Directors. Directors are
elected by the stockholders at annual meetings of the Company. Maryland law
requires that certain major corporate transactions, including most amendments to
the Charter, may not be consummated without the approval of stockholders as set
forth below. All holders of common stock have one vote per share, and the
Charter permits the Board of Directors to classify and issue preferred stock in
one or more series having voting power which may differ from that of the common
stock. See "Description of Capital Stock."

<PAGE>   63
 
     The following is a comparison of the voting rights of the common limited
partners of the Operating Partnership and the common stockholders of the Company
as they relate to certain major transactions:
 
 
A. AMENDMENT OF THE PARTNERSHIP AGREEMENT OR THE CHARTER.
 
OPERATING PARTNERSHIP

The Partnership Agreement may be amended through a proposal by the general
partner or any limited partners holding 25% or more of the then outstanding
Units entitled to vote. Generally, the Partnership Agreement may be amended with
the approval of the Company as general partner and partners (including the
Company but not including the preferred limited partners) holding a majority of
the percentage interest of all partners other than preferred limited partners.
Certain provisions regarding, among other things, the rights and duties of the
Company as general partner and the dissolution of the Operating Partnership, may
not be amended without the approval of the limited partners (other than
preferred limited partners) holding a majority of the percentage interests of
the limited partners other than preferred limited partners. Certain amendments
that affect the fundamental rights of a limited partner must be approved by the
Company and each limited partner that would be adversely affected. The Company
may, without the limited partners' consent, amend the Partnership Agreement to
establish rights, powers, duties and preferences of additional partnership
interests issued in accordance with the Partnership Agreement and to reflect
certain ministerial matters.
 
COMPANY

Amendments to the Company's Charter must be advised by the Board of Directors
and approved by the vote of at least two-thirds of the votes entitled to be cast
on the matter at a meeting of stockholders.
 
                                       60
<PAGE>   64
 
B. VOTE REQUIRED TO DISSOLVE THE OPERATING PARTNERSHIP OR THE COMPANY.
 
OPERATING PARTNERSHIP

The general partner may not elect to dissolve the Operating Partnership without
the prior consent of limited partners (other than the preferred limited
partners) holding a majority of the outstanding percentage interest of all
limited partners other than preferred limited partners.
 
COMPANY

Under Maryland Law, the Company may be dissolved by the affirmative vote of a
majority of the Board of Directors declaring the dissolution to be advisable and
approval of holders of at least two-thirds of the total number of shares of
capital stock outstanding and entitled to vote on the matter. The Partnership
Agreement provides that the Company may not withdraw from the Operating
Partnership (whether by sale, statutory merger, consolidation, liquidation or
otherwise) without the consent of limited partners (other than the preferred
limited partners) holding a majority of the outstanding percentage interest of
all limited partners other than preferred limited partners. However, as
described below under "-- Vote Required to Sell Assets or Merge," the Company
may transfer or assign its general partner interest in connection with a merger,
consolidation or sale of substantially all of its assets without limited partner
consent, upon certain terms and conditions.
 
                                       61
<PAGE>   65
 
C. VOTE REQUIRED TO SELL ASSETS OR MERGE.
 
OPERATING PARTNERSHIP

Under the Partnership Agreement, the sale, exchange, transfer or other
disposition of all or substantially all of the Operating Partnership's assets
requires the consent of the partners (other than the preferred limited partners)
holding a majority of the percentage interest of all partners other than
preferred limited partners. The merger, consolidation or other combination of
the Operating Partnership also requires the consent of the partners (other than
the preferred limited partners) holding a majority of the percentage interest of
all partners other than preferred limited partners.
 
COMPANY

Under Maryland law, the sale of all or substantially all of the assets of the
Company or merger or consolidation of the Company requires the approval of the
Board of Directors and the stockholders by the affirmative vote of two-thirds of
all the votes entitled to be cast on the matter. The stockholders are not
required to approve the sale of less than all or substantially all of the
Company's assets.
 
Pursuant to the Partnership Agreement, the Company may not withdraw from the
Operating Partnership and may not transfer all or any portion of its interest in
the Operating Partnership (whether by sale, statutory merger, consolidation,
liquidation or otherwise) without the consent of limited partners (other than
the preferred limited partners) holdings a majority of the outstanding
percentage interest of all limited partners other than preferred limited
partners. However, the Company may transfer or assign its general partner
interest in connection with a merger, consolidation or sale of substantially all
of its assets without limited partner consent if the conditions described under
"Description of Certain Provisions of the Partnership Agreement of the Operating
Partnership -- Removal of the General Partner; Transferability of Our Interests;
Treatment of Limited Partnership Units in Significant Transactions" are met.
These conditions generally relate to receipt by the common limited partners of
property that the partner would have received had it exchanged its common Units
for shares of common stock immediately prior to the transaction.

                      COMPENSATION, FEES AND DISTRIBUTIONS
 
OPERATING PARTNERSHIP

The general partner does not receive any compensation for its services as
general partner of the Operating Partnership. As a partner in the Operating
Partnership, however, the general partner has the same right to allocations and
distributions as other partners of the Operating Partnership. In addition, the
Operating Partnership will reimburse the Company for all expenses it incurs
relating to its activities as general partner, its continued existence and
qualification as a REIT and all other liabilities that it incurs in connection
with the pursuit of its business and affairs. The Operating Partnership will
reimburse the Company for all expenses incurred relating to the ongoing
operation of the Company and any issuance of additional partnership interests in
the Operating Partnership. These expenses include those incurred in connection
with the administration and activities of the Operating Partnership, such as the
maintenance of the Operating Partnership's books and records, management of the
Operating Partnership's property and assets, and preparation of information
regarding the Operating Partnership provided to the partners in the preparation
of their individual tax returns. Except as expressly permitted by the
Partnership Agreement, however, the Company's affiliates will not engage in any
transactions with the Operating Partnership except on terms that are fair and
reasonable to the Operating Partnership and no less favorable to the Operating
Partnership than it would obtain from an unaffiliated third party.
 
COMPANY

The outside directors and officers of the Company receive compensation for their
services.
 
                             LIABILITY OF INVESTORS
 
OPERATING PARTNERSHIP

Under the Partnership Agreement and applicable Delaware law, the liability of
the limited partners for the Operating Partnership's debts and obligations is
generally limited to the amount of their investment in the Operating
Partnership.
 
COMPANY

Under Maryland law, stockholders are generally not personally liable for the
debts or obligations of the Company.

<PAGE>   67
 
                                   LIQUIDITY
 
OPERATING PARTNERSHIP

Subject to certain conditions, limited partners may generally transfer their
Units to accredited investors, provided that the Company has a right of first
refusal for any proposed transfer. Limited partners may transfer their Units
without the Company's consent in the following situations:
 
- - transfers to the general partner,
 
- - transfers to an affiliate controlled by the limited partner or to immediate
  family members;
 
- - transfers to a trust for the benefit of a charitable beneficiary or to a
  charitable foundation; or
 
- - transfers pursuant to a pledge to an unaffiliated lending institution as
  collateral or security for a loan or other extension of credit.
 
COMPANY

A limited partner is entitled to freely transfer the shares of common stock
received by that partner in exchange for Units, subject to prospectus delivery
and other requirements for registered securities. The common stock is listed on
the New York Stock Exchange. The breadth and strength of this secondary market
will depend, among other things, upon the number of shares outstanding, the
Company's financial results and prospects, the general interest in the Company's
and other real estate investments, and the Company's dividend yield compared to
that of other debt and equity securities.

                                     TAXES
 
OPERATING PARTNERSHIP

The Operating Partnership itself is not subject to federal income taxes.
Instead, each holder of Units includes its allocable share of the Operating
Partnership's taxable income or loss in determining its individual federal
income tax liability. Cash distributions from the Operating Partnership are
generally not taxable to a holder of Units except to the extent they exceed the
holder's basis in its interest in the Operating Partnership (which will include
such holder's allocable share of the Operating Partnership's nonrecourse debt).
 
COMPANY

Distributions made by the Company to its taxable domestic stockholders out of
current or accumulated earnings and profits will be taken into account by them
as ordinary income. Distributions that are designated as capital gain dividends
generally will be taxed as gains from the sale or disposition of a capital
asset. Distributions in excess of current or accumulated earnings and profits
will be treated as a nontaxable return of basis to the extent of a stockholder's
adjusted basis in its common stock, with the excess taxed as capital gain. See
"Certain Federal Income Tax Considerations -- Taxation of Taxable U.S.
Stockholders."
 
Income and loss from the Operating Partnership generally is subject to the
"passive activity" limitations. Under the "passive activity" rules, partners can
generally offset income and loss from the Operating Partnership that is
considered "passive income" against income and loss from other investments that
constitute "passive activities." However, this offset will not be available if
the Operating Partnership becomes a publicly traded partnership (as defined in
the Code).
 
Holders of Units are required, in some cases, to file state income tax returns
and/or pay state income taxes in the states in which the Operating Partnership
owns property, even if they are not residents of those states.

Dividends paid by the Company will be treated as "portfolio" income and
stockholders cannot offset these dividends with losses from "passive
activities."

Stockholders who are individuals generally will not be required to file state
income tax returns and/or pay state income taxes outside of their state of
residence with respect to the Company's operations and distributions. The
Company may be required to pay state income taxes in certain states.

                   CERTAIN PROVISIONS OF MARYLAND LAW AND OF
                             OUR CHARTER AND BYLAWS
 
     We have summarized certain terms and provisions of the MGCL and our Charter
and Bylaws. This summary is not complete and is qualified by the provisions of
our Charter and Bylaws, and the MGCL. For more detail, you should refer to our
Charter and Bylaws, which we have filed as exhibits to the registration
statement of which this prospectus is a part. See "Where You Can Find More
Information."
 
BOARD OF DIRECTORS
 
     The Charter provides that the number of our directors shall be established
by the Bylaws, but cannot be less than the minimum number required by the MGCL,
which in the case of the Company is three. Our Bylaws currently provide that the
Board of Directors consists of not fewer than five nor more than 13 members who
are elected to a one-year term at each annual meeting of our stockholders. A
majority of the entire Board of Directors may fill any vacancy (except for a
vacancy caused by removal). Our Bylaws provide that a majority of the Board of
Directors must be "Independent Directors." An "Independent Director" is a
director who is not:
 
     - an employee, officer or affiliate of us or one of our subsidiaries or
       divisions;
 
     - a relative of a principal executive officer; or
 
     - an individual member of an organization acting as advisor, consultant or
       legal counsel, receiving compensation on a continuing basis from us in
       addition to director's fees.
 
REMOVAL OF DIRECTORS
 
     While our Charter and the MGCL empower our stockholders to fill vacancies
in the Board of Directors that are caused by the removal of a director, our
Charter precludes stockholders from removing incumbent directors except upon a
substantial affirmative vote. Specifically, our Charter provides that
stockholders may remove a director only for cause and only by the affirmative
vote of at least two-thirds of the votes entitled to be cast in the election of
directors, subject to the rights of the holders of shares of our preferred stock
to elect and remove directors elected by such holders under certain
circumstances. The MGCL does not define the term "cause." As a result, removal
for "cause" is subject to Maryland common law and to judicial interpretation and
review in the context of the unique facts and circumstances of any particular
situation. This provision, when coupled with the provision in our Bylaws
authorizing the Board of Directors to fill vacant directorships, precludes
stockholders from removing incumbent directors except upon a substantial
affirmative vote and filling the vacancies created by removal with their own

     We have elected in our Bylaws not to be governed by the "control share
acquisition" provisions of the MGCL (Sections 3-701 through 3-709), and the
Board of Directors has determined, by irrevocable resolution, that we will not
be governed by the "business combination" provision of the MGCL (Section 3-602),
each of which could have the effect of delaying or preventing a change of
control. Our Bylaws provide that we cannot at a future date determine to be
governed by either provision without the approval of a majority of the
outstanding shares entitled to vote. In addition, the irrevocable resolution
 
                                       66
<PAGE>   70
 
adopted by the Board of Directors may only be changed by the approval of a
majority of the outstanding shares entitled to vote.
 
AMENDMENT TO OUR CHARTER AND BYLAWS
 
     Our Charter may not be amended without the affirmative vote of at least
two-thirds of the shares of capital stock outstanding and entitled to vote on
the amendment, voting together as a single class. Our Bylaws may be amended by
the vote of a majority of the Board of Directors or by a vote of a majority of
the shares of our capital stock entitled to vote on the amendment, except with
respect to the following Bylaw provisions (each of which requires the approval
of a majority of the shares of capital stock entitled to vote on the amendment):
 
     - provisions opting out of the control share acquisition statute;
 
     - the requirement in our Bylaws that our independent directors approve
       transactions involving our executive officers or directors or any limited
       partners of the Operating Partnership and their affiliates;
 
     - provisions governing amendment of our Bylaws.
 
MEETINGS OF STOCKHOLDERS
 
     Our Bylaws provide for annual meetings of stockholders to elect the Board
of Directors and transact other business as may properly be brought before the
meeting. The President, the Board of Directors and the Chairman of the Board may
call a special meeting of stockholders. The holders of 50% or more of our
outstanding stock entitled to vote may also make a written request to call a
special meeting of stockholders.
 
     The MGCL provides that stockholders may act by unanimous written consent
without a meeting with respect to any action that they are required or permitted
to take at a meeting, if each stockholder entitled to vote on the matter signs
the consent setting forth the action and each stockholder entitled to notice of
the meeting but not entitled to vote at the meeting signs a written waiver of
any right to dissent.
 
ADVANCE NOTICE OF DIRECTOR NOMINATIONS AND NEW BUSINESS
 
     Our Bylaws provide that with respect to an annual meeting of stockholders,
nominations of persons for election to the Board of Directors and the proposal
of business to be considered by stockholders may be made only:
 
     - pursuant to the notice of the meeting;
 
     - by or at the direction of the Board of Directors; or
 
     - by a stockholder who is entitled to vote at the meeting and has complied
       with the advance notice procedures set forth in our Bylaws.
 
     Our Bylaws also provide that with respect to special meetings of
stockholders, only the business specified in the notice of meeting may be
brought before the meeting.
 
     The provisions in our Charter regarding amendments to the Charter and the
advance notice provisions of our Bylaws could have the effect of discouraging a
takeover or other transaction in which holders of some, or a majority, of the
shares of common stock might receive a premium for their shares over the then
prevailing market price or which holders might believe to be otherwise in their
best interests.

DISSOLUTION OF THE COMPANY
 
     Under the MGCL, we may be dissolved by the affirmative vote of a majority
of the entire Board of Directors declaring dissolution to be advisable and
directing that the proposed dissolution be submitted for consideration at any
annual or special meeting of stockholders. We may also be dissolved, upon proper
notice, by the affirmative vote of the holders of two-thirds of the total number
of shares of capital stock outstanding and entitled to vote on the dissolution,
voting as a single class.
 
LIMITATION OF DIRECTORS' AND OFFICERS' LIABILITY
 
     Our officers and directors are indemnified under the MGCL, our Charter and
the Partnership Agreement against certain liabilities. Our Charter and Bylaws
require us to indemnify our directors and officers to the fullest extent
permitted from time to time by the MGCL.
 
     The MGCL permits a corporation to indemnify its directors and officers and
certain other parties against judgments, penalties, fines, settlements and
reasonable expenses actually incurred by them in connection with any proceeding
to which they may be made a party by reason of their service in those or other
capacities unless:
 
     - the act or omission of the director or officer was material to the matter
       giving rise to the proceeding and was committed in bad faith or was the
       result of active and deliberate dishonesty;
 
     - the director or officer actually received an improper personal benefit in
       money, property or services; or
 
     - in the case of any criminal proceeding, the director or officer had
       reasonable cause to believe that the act or omission was unlawful.
 
     A corporation may indemnify a director or officer against judgments,
penalties, fines, settlements and reasonable expenses that the director or
officer actually incurs in connection with the proceeding unless the proceeding
is one by or in the right of the corporation and the director or officer has
been adjudged to be liable to the corporation. In addition, a corporation may
not indemnify a director or officer with respect to any proceeding charging
improper personal benefit to the director or officer in which the director or
officer was adjudged to be liable on the basis that personal benefit was
received. The termination of any proceeding by conviction, or upon a plea of
nolo contendere or its equivalent, or an entry of any order of probation prior
to judgment, creates a rebuttable presumption that the director or officer did
not meet the requisite standard of conduct required for indemnification to be
permitted.
 
     The MGCL permits the charter of a Maryland corporation to include a
provision limiting the liability of its directors and officers to the
corporation and its stockholders for money damages, subject to specified
restrictions. Our Charter contains this provision. The MGCL does not, however,
permit the liability of directors and officers to the corporation or its
stockholders to be limited to the extent that:
 
     - it is proved that the person actually received an improper personal
       benefit in money, property or services;
 
     - a judgment or other final adjudication is entered in a proceeding based
       on a finding that the person's action, or failure to act, was committed
       in bad faith or was the result of active and deliberate dishonesty and
       was material to the cause of action adjudicated in the proceeding; or
 
                                       68
<PAGE>   72
 
     - in the case of any criminal proceeding, the director had reasonable cause
       to believe that the act or failure to act was unlawful.
 
     This provision does not limit our ability or our stockholders to obtain
other relief, such as an injunction or rescission. The Partnership Agreement
also provides for our indemnification, as general partner, and our officers and
directors to the same extent indemnification is provided to our officers and
directors in our Charter, and limits our liability and the liability of our
officers and directors to the Operating Partnership and the partners of the
Operating Partnership to the same extent liability of our officers and directors
to us and our stockholders is limited under our Charter. See "Description of
Certain Provisions of the Partnership Agreement of the Operating
Partnership -- Our Exculpation and Indemnification."
 
     Insofar as the foregoing provisions permit indemnification for liability
arising under the Securities Act of directors, officers or persons controlling
us, we have been informed that, in the opinion of the SEC, this indemnification
is against public policy as expressed in the Securities Act and is therefore
unenforceable.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
     The following summary of certain federal income tax considerations
regarding the Company and the common stock we are registering is based on
current law, is for general information only and is not tax advice. The
information set forth below, to the extent that it constitutes matters of law,
summaries of legal matters or legal conclusions, is the opinion of Latham &
Watkins. The tax treatment to holders of common stock or common Units will vary
depending on a holder's particular situation and this discussion does not
purport to deal with all aspects of taxation that may be relevant to a holder of
common stock or common Units in light of his or her personal investments or tax
circumstances, or to certain types of stockholders, subject to special treatment
under the federal income tax laws except to the extent discussed under the
headings "-- Taxation of Tax-Exempt Stockholders" and "-- Taxation of Non-U.S.
Stockholders." Stockholders subject to special treatment include, without
limitation, insurance companies, financial institutions or broker-dealers,
tax-exempt organizations, stockholders holding securities as part of a
conversion transaction, or a hedge or hedging transaction or as a position in a
straddle for tax purposes, foreign corporations or partnerships and persons who
are not citizens or residents of the United States. In addition, the summary
below does not consider the effect of any foreign, state, local or other tax
laws that may be applicable to holders of our common stock.
 
     The information in this section is based on the Code, current, temporary
and proposed Treasury Regulations promulgated under the Code, the legislative
history of the Code, current administrative interpretations and practices of the
Internal Revenue Service (the "IRS") (including its practices and policies as
expressed in certain private letter rulings which are not binding on the IRS
except with respect to the particular taxpayers who requested and received such
rulings), and court decisions, all as of the date of this prospectus. Future
legislation, Treasury Regulations, administrative interpretations and practices
and/or court decisions may adversely affect, perhaps retroactively, the tax
considerations described herein. We have not requested, and do not plan to
request, any rulings from the IRS concerning our tax treatment and the
statements in this prospectus are not binding on the IRS or a court. Thus, we
can provide no assurance that these statements will not be challenged by the IRS
or sustained by a court if challenged by the IRS.
 
     YOU ARE ADVISED TO CONSULT YOUR TAX ADVISOR REGARDING THE SPECIFIC TAX
CONSEQUENCES TO YOU OF THE DISPOSITION OF COMMON UNITS AND THE ACQUISITION,
OWNERSHIP AND SALE OF OUR COMMON STOCK, INCLUDING THE FEDERAL, STATE, LOCAL,
FOREIGN AND OTHER TAX CONSEQUENCES OF SUCH DISPOSITION, ACQUISITION, OWNERSHIP
AND SALE AND OF POTENTIAL CHANGES IN APPLICABLE TAX LAWS.
 
TAX CONSIDERATIONS OF THE EXERCISE OF REDEMPTION RIGHTS
 
     The exchange of the common Units held by a limited partner of the Operating
Partnership for shares of our common stock, or a redemption of such units for
cash, will be treated for tax purposes as a sale of the common Units by the
limited partner. A limited partner will recognize gain or loss for income tax
purposes in an amount equal to the difference between the "amount realized" by
the limited partner in the exchange or redemption and the limited partner's
adjusted tax basis in the common Units exchanged or redeemed. Generally, the
amount realized by a limited partner on an exchange or
 
                                       70
<PAGE>   74
 
redemption will be the fair market value of the exchanged shares received in the
exchange, with the amount of cash received in the redemption, plus the amount of
the Operating Partnership's liabilities allocable to the common Units being
exchanged or redeemed. However, in the event that the Company elects to cause
the Operating Partnership to pay a limited partner cash for a portion of his or
her common Units, under certain circumstances, the limited partner may recognize
gain only to the extent the cash received for such common Units, plus the amount
of any reduction of Operating Partnership liabilities allocable to the limited
partner, exceed the limited partner's basis in all of his or her common Units
prior to such payment. The recognition of any loss resulting from an exchange of
common Units for shares of common stock or a redemption of common Units for cash
is subject to a number of limitations set forth in the Code. The character of
any such gain or loss as capital or ordinary will depend on the nature of the
assets of the Operating Partnership at the time of the redemption or exchange.
 
TAXATION OF THE COMPANY
 
     General. We elected to be taxed as a REIT under Sections 856 through 860 of
the Code, commencing with our taxable year ended December 31, 1997. We believe
we have been organized and have operated in a manner which allows us to qualify
for taxation as a REIT under the Code commencing with our taxable year ended
December 31, 1997. We intend to continue to operate in this manner. However, our
qualification and taxation as a REIT depends upon our ability to meet (through
actual annual operating results, asset diversification, distribution levels and
diversity of stock ownership) the various qualification tests imposed under the
Code. Accordingly, there is no assurance that we have operated or will continue
to operate in a manner so as to qualify or remain qualified as a REIT. See
"-- Failure to Qualify."
 
     The sections of the Code that relate to the qualification and operation as
a REIT are highly technical and complex. The following sets forth the material
aspects of the sections of the Code that govern the federal income tax treatment
of a REIT and its stockholders. This summary is qualified in its entirety by the
applicable Code provisions, relevant rules and regulations promulgated under the
Code, and administrative and judicial interpretations of the Code.
 
     If we qualify for taxation as a REIT, we generally will not be subject to
federal corporate income taxes on our net income that is currently distributed
to our stockholders. This treatment substantially eliminates the "double
taxation" (once at the corporate level when earned and once again at the
stockholder level when distributed) that generally results from investment in a
corporation. However, the Company will be subject to federal income tax as
follows:
 
     First, we will be taxed at regular corporate rates on any undistributed
REIT taxable income, including undistributed net capital gains.
 
     Second, we may be subject to the "alternative minimum tax" on our items of
tax preference under certain circumstances.
 
     Third, if we have (a) net income from the sale or other disposition of
"foreclosure property" (defined generally as property we acquired through
foreclosure or after a default on a loan secured by the property or a lease of
the property) which is held primarily for sale to customers in the ordinary
course of business or (b) other nonqualifying income from foreclosure property,
we will be subject to tax at the highest corporate rate on this income.
 
                                       71
<PAGE>   75
 
     Fourth, we will be subject to a 100% tax on any net income from prohibited
transactions (which are, in general, certain sales or other dispositions of
property held primarily for sale to customers in the ordinary course of business
other than foreclosure property).
 
     Fifth, we will be subject to a 100% tax on an amount equal to (a) the gross
income attributable to the greater of the amount by which we fail the 75% or 95%
gross income test multiplied by (b) a fraction intended to reflect our
profitability, if we fail to satisfy the 75% gross income test or the 95% gross
income test (as discussed below), but have maintained our qualification as a
REIT because we satisfied certain other requirements.
 
     Sixth, we would be subject to a 4% excise tax on the excess of the required
distribution over the amounts actually distributed if we fail to distribute
during each calendar year at least the sum of (i) 85% of our REIT ordinary
income for the year, (ii) 95% of our REIT capital gain net income for the year,
and (iii) any undistributed taxable income from prior periods.
 
     Seventh, if we acquire any asset (a "Built-In Gain Asset") from a
corporation which is or has been a C corporation (i.e., generally a corporation
subject to full corporate-level tax) in a transaction in which the basis of the
Built-In Gain Asset in our hands is determined by reference to the basis of the
asset in the hands of the C corporation, and we subsequently recognize gain on
the disposition of the asset during the ten-year period (the "Recognition
Period") beginning on the date on which we acquired the asset, then we will be
subject to tax at the highest regular corporate tax rate on this gain to the
extent of the Built-In Gain (i.e., the excess of (a) the fair market value of
the asset over (b) our adjusted basis in the asset, in each case determined as
of the beginning of the Recognition Period). The results described in this
paragraph with respect to the recognition of Built-In Gain assume that we will
make an election pursuant to IRS Notice 88-19.
 
     Requirements for Qualification as a REIT. The Code defines a REIT as a
corporation, trust or association:
 
     (1) that is managed by one or more trustees or directors;
 
     (2) that issues transferable shares or transferable certificates to
         evidence its beneficial ownership;
 
     (3) that would be taxable as a domestic corporation, but for Sections 856
         through 859 of the Code;
 
     (4) that is not a financial institution or an insurance company within the
         meaning of certain provisions of the Code;
 
     (5) that is beneficially owned by 100 or more persons;
 
     (6) not more than 50% in value of the outstanding stock of which is owned,
         actually or constructively, by five or fewer individuals (as defined in
         the Code to include certain entities) during the last half of each
         taxable year; and
 
     (7) that meets certain other tests, described below, regarding the nature
         of its income and assets and the amount of its distributions.
 
     The Code provides that conditions (1) to (4), inclusive, must be met during
the entire taxable year and that condition (5) must be met during at least 335
days of a taxable year of twelve months, or during a proportionate part of a
taxable year of less than twelve months. Conditions (5) and (6) do not apply
until after the first taxable year for which an election is made to be taxed as
a REIT. For purposes of condition (6), pension
 
                                       72
<PAGE>   76
 
funds and certain other tax-exempt entities are treated as individuals, subject
to a "look-through" exception with respect to pension funds.
 
     We believe that we have satisfied each of the above conditions. In
addition, our charter provides for restrictions regarding ownership and transfer
of shares. These restrictions are intended to assist us in continuing to satisfy
the share ownership requirements described in (5) and (6) above. These ownership
and transfer restrictions are described in "Description of Capital
Stock -- Restrictions on Ownership and Transfer of Capital Stock." These
restrictions, however, may not ensure that we will, in all cases, be able to
satisfy the share ownership requirements described in (5) and (6) above. If we
fail to satisfy these share ownership requirements, our status as a REIT will
terminate. However, if we comply with the rules contained in applicable Treasury
Regulations that require us to ascertain the actual ownership of our shares and
we do not know, or would not have known through the exercise of reasonable
diligence, that we failed to meet the requirement described in condition (6)
above, we will be treated as having met this requirement. See "-- Failure to
Qualify."
 
     In addition, a corporation may not elect to become a REIT unless its
taxable year is the calendar year. We have and will continue to have a calendar
taxable year.
 
     Termination of S Status. Prior to its merger into the Company in connection
with our formation transactions, AMB Institutional Realty Advisors, Inc.
believed that it validly elected to be taxed as an S corporation and that such
election had not been revoked or otherwise terminated (except as provided
below). In order to allow us to become a REIT, AMB Institutional Realty
Advisors, Inc. revoked its S election shortly before its merger into the
Company. If AMB Institutional Realty Advisors, Inc. was not an S corporation in
1997 (the calendar year in which our formation transactions occurred), we likely
would not qualify as a REIT for our taxable year ended December 31, 1997 and
perhaps subsequent years. See "-- Failure to Qualify." In connection with our
initial public offering, Latham & Watkins rendered an opinion regarding AMB
Institutional Realty Advisors, Inc.'s federal income tax status as an S
corporation, which opinion was based upon certain representations made by AMB
Institutional Realty Advisors, Inc. as to factual matters and upon the opinion
of counsel for certain shareholders of AMB Institutional Realty Advisors, Inc.,
with respect to matters relating to the tax status of such shareholders.
 
     Ownership of Interests in Partnerships and Qualified REIT Subsidiaries. In
the case of a REIT which is a partner in a partnership, IRS regulations provide
that the REIT will be deemed to own its proportionate share of the assets of the
partnership. Also, the REIT will be deemed to be entitled to the income of the
partnership attributable to its proportionate share. The character of the assets
and gross income of the partnership retains the same character in the hands of
the REIT for purposes of Section 856 of the Code, including satisfying the gross
income tests and the asset tests. Thus, our proportionate share of the assets
and items of income of the Operating Partnership (including the Operating
Partnership's share of these items for any partnership in which it owns an
interest) are treated as our assets and items of income for purposes of applying
the requirements described in this prospectus (including the income and asset
tests described below). We have included a brief summary of the rules governing
the federal income taxation of partnerships and their partners below in "--Tax
Aspects of the Operating Partnerships and the Joint Ventures." We have direct
control of the Operating Partnership and will continue to operate it consistent
with the requirements for qualification as a REIT. However, we are a limited
partner or non-managing member in certain of our joint ventures. If a joint
venture takes or expects to take actions which could jeopardize our
 
                                       73
<PAGE>   77
 
status as a REIT or subject us to tax, we may be forced to dispose of our
interest in such joint venture. In addition, it is possible that a joint venture
could take an action which could cause us to fail a REIT income or asset test,
and that we would not become aware of such action in a time frame which would
allow us to dispose of our interest in the joint venture or take other
corrective action on a timely basis. In such a case, we could fail to qualify as
a REIT. The Company owns 100% of the stock of two subsidiaries that are
qualified REIT subsidiaries (each, a "QRS") and may acquire stock of one or more
new subsidiaries. A corporation will qualify as a QRS if 100% of its stock is
held by the Company. A QRS will not be treated as a separate corporation, and
all assets, liabilities and items of income, deduction and credit of a QRS will
be treated as assets, liabilities and such items (as the case may be) of the
Company for all purposes of the Code, including the REIT qualification tests.
For this reason, references under "Certain Federal Income Tax Considerations" to
our income and assets shall include the income and assets of any QRS. A QRS will
not be subject to federal income tax, and our ownership of the voting stock of a
QRS will not violate the restrictions against ownership of securities of any one
issuer which constitute more than 10% of such issuer's voting securities or more
than 5% of the value of our total assets, as described below under "-- Asset
Tests."
 
     Income Tests. We must satisfy two gross income requirements annually to
maintain our qualification as a REIT. First, in each taxable year we must derive
directly or indirectly at least 75% of our gross income (excluding gross income
from prohibited transactions) 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,
each taxable year we must derive at least 95% of our gross income (excluding
gross income from prohibited transactions) from these real property investments,
dividends, interest and gain from the sale or disposition of stock or securities
(or from any combination of the foregoing). The term "interest" generally does
not include any amount received or accrued (directly or indirectly) if the
determination of the amount depends in whole or in part on the income or profits
of any person. However, an amount received or accrued generally will not be
excluded from the term "interest" solely by reason of being based on a fixed
percentage or percentages of receipts or sales.
 
     Rents we receive will qualify as "rents from real property" in satisfying
the gross income requirements for a REIT described above only if the following
conditions are met:
 
     - the amount of rent must not be based in whole or in part on the income or
       profits of any person. However, an amount received or accrued generally
       will not be excluded from the term "rents from real property" solely by
       reason of being based on a fixed percentage or percentages of receipts or
       sales;
 
     - 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 actual or constructive owner of 10% or more of the REIT,
       actually or constructively owns 10% or more of the interests in such
       tenant (a "Related Party Tenant");
 
     - 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 personal
       property will not qualify as "rents from real property"; and
 
     - for rents received to qualify as "rents from real property," the REIT
       generally must not operate or manage the property or furnish or render
       services to the tenants of
 
                                       74
<PAGE>   78
 
       the property (subject to a 1% de minimis exception), other than through
       an independent contractor from whom the REIT derives no revenue. The REIT
       may, however, directly perform certain services that are "usually or
       customarily rendered" in connection with the rental of space for
       occupancy only and are not otherwise considered "rendered to the
       occupant" of the property.
 
     We do not and will not, and as general partner of the Operating
Partnership, will not permit the Operating Partnership to:
 
     - 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
       percentage of receipts or sales, as described above);
 
     - rent any property to a Related Party Tenant;
 
     - derive rental income attributable to personal property (other than
       personal property leased in connection with the lease of real property,
       the amount of which is less than 15% of the total rent received under the
       lease); or
 
     - perform services considered to be rendered to the occupant of the
       property, other than through an independent contractor from whom we
       derive no revenue.
 
Notwithstanding the foregoing, we may have taken and may continue to take
certain of the actions set forth above to the extent these actions will not,
based on the advice of our tax counsel, jeopardize our status as a REIT.
 
     AMB Investment Management is the sole general partner of, and conducts its
operations through, AMB Investment Management Limited Partnership (the
"Investment Management Partnership.") The Investment Management Partnership
conducts the asset management business and receives fees (including incentive
fees) in exchange for the provision of certain services to asset management
clients. In addition, Headlands Realty Corporation may provide certain services
in exchange for a fee or derive other income which would not qualify under the
REIT gross income tests. Such fees and other income do not accrue to us, but we
derive our allocable share of dividend income from the Preferred Stock
Subsidiaries through our interest in the Operating Partnership. Such dividend
income qualifies under the 95%, but not the 75%, REIT gross income test. The
Operating Partnership may provide certain management or administrative services
to the Investment Management Partnership and Headlands Realty Corporation. The
fees derived by the Operating Partnership as a result of the provision of such
services will be nonqualifying income to us under both the 95% and 75% REIT
income tests. The amount of such dividend and fee income will depend on a number
of factors which cannot be determined with certainty, including the level of
services provided by the Investment Management Partnership, Headlands Realty
Corporation and the Operating Partnership. We will monitor the amount of the
dividend income from the Preferred Stock Subsidiaries and the fee income
described above, and will take actions intended to keep this income (and any
other nonqualifying income) within the limitations of the REIT income tests.
However, there can be no assurance that such actions will in all cases prevent
us from violating a REIT income test.
 
     If we fail to satisfy one or both of the 75% or 95% gross income tests for
any taxable year, we may nevertheless qualify as a REIT for the year if we are
entitled to relief under certain provisions of the Code. Generally, we may avail
ourselves of the relief provisions if:
 
     - our failure to meet these tests was due to reasonable cause and not due
       to willful neglect;
 
                                       75
<PAGE>   79
 
     - we attach a schedule of the sources of our income to our federal income
       tax return; and
 
     - any incorrect information on the schedule was not due to fraud with
       intent to evade tax.
 
It is not possible, however, to state whether in all circumstances we would be
entitled to the benefit of these relief provisions. For example, if we fail to
satisfy the gross income tests because nonqualifying income that we
intentionally incur exceeds the limits on nonqualifying income, the IRS could
conclude that our failure to satisfy the tests was not due to reasonable cause.
If these relief provisions do not apply to a particular set of circumstances, we
will not qualify as a REIT. As discussed above in "-- Taxation of the
Company -- General," even if these relief provisions apply, and we retain our
status as a REIT, a tax would be imposed with respect to our excess net income.
We may not always be able to maintain compliance with the gross income tests for
REIT qualification despite our periodic monitoring of our income.
 
     Prohibited Transaction Income. Any gain realized by us on the sale of any
property held as inventory or other property held primarily for sale to
customers in the ordinary course of business (including our share of any such
gain realized by the Operating Partnership) will be treated as income from a
prohibited transaction that is subject to a 100% penalty tax. This prohibited
transaction income may also adversely affect our ability to satisfy the income
tests for qualification as a REIT. Under existing law, whether property is held
as inventory or primarily for sale to customers in the ordinary course of a
trade or business is a question of fact that depends on all the facts and
circumstances surrounding the particular transaction. The Operating Partnership
intends to hold its properties for investment with a view to long-term
appreciation, to engage in the business of acquiring, developing and owning its
properties and to make occasional sales of the properties as are consistent with
the Operating Partnership's investment objectives. However, the IRS may contend
that that one or more of these sales is subject to the 100% penalty tax.
 
     Asset Tests. At the close of each quarter of our taxable year, we also must
satisfy three tests relating to the nature and diversification of our assets.
First, at least 75% of the value of our total assets must be represented by real
estate assets, cash, cash items and government securities. For purposes of this
test, real estate assets include stock or debt instruments that are purchased
with the proceeds of a stock offering or a long-term (at least five years)
public debt offering, but only for the one-year period beginning on the date we
receive such proceeds. Second, not more than 25% of our total assets may be
represented by securities, other than those securities includable in the 75%
asset test. Third, of the investments included in the 25% asset class, the value
of any one issuer's securities may not exceed 5% of the value of our total
assets and we may not own more than 10% of any one issuer's outstanding voting
securities.
 
     The Operating Partnership owns 100% of the non-voting preferred stock of
each of the Preferred Stock Subsidiaries, and by virtue of its ownership of
interests in the Operating Partnership, the Company is considered to own its pro
rata share of such stock. See "Structure of the Company." The stock of each of
the Preferred Stock Subsidiaries held by us is not a qualifying real estate
asset. The Operating Partnership does not and will not own any of the voting
securities of either of the Preferred Stock Subsidiaries, and therefore we will
not be considered to own more than 10% of the voting securities of either of the
Preferred Stock Subsidiaries. In addition, we believe that the value of our pro
rata share of the securities of each of the Preferred Stock Subsidiaries held by
the Operating
 
                                       76
<PAGE>   80
 
Partnership does not, in either case, exceed 5% of the total value of our
assets, and will not exceed such amount in the future. No independent appraisals
have been obtained to support this conclusion. There can be no assurance that
the IRS will not contend that the value of the securities of one or both of the
Preferred Stock Subsidiaries held by us exceeds the 5% value limitation. The 5%
value test must be satisfied not only on the date that we (directly or through
the Operating Partnership) acquire securities in the applicable Preferred Stock
Subsidiary, but also each time we increase our ownership of securities of such
Preferred Stock Subsidiary, including as a result of increasing our interest in
the Operating Partnership. For example, our indirect ownership of securities of
each Preferred Stock Subsidiary will increase as a result of our capital
contributions to the Operating Partnership or as limited partners exercise their
redemption/exchange rights. Although we believe that we presently satisfy the 5%
value test and plan to take steps to ensure that we satisfy such test for any
quarter with respect to which retesting is to occur, there can be no assurance
that such steps will always be successful, or will not require a reduction in
the Operating Partnership's overall interest in either or both of the Preferred
Stock Subsidiaries.
 
     After initially meeting the asset tests at the close of any quarter, we
will not lose our 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 we fail
to satisfy the asset tests because we acquire securities or other property
during a quarter (including an increase in our interests in the Operating
Partnership), we can cure this failure by disposing of sufficient nonqualifying
assets within 30 days after the close of that quarter. We believe we have
maintained and intend to continue to maintain adequate records of the value of
our assets to ensure compliance with the asset tests and to take such other
actions within the 30 days after the close of any quarter as may be required to
cure any noncompliance. If we fail to cure noncompliance with the asset tests
within this time period, we would cease to qualify as a REIT.
 
     Annual Distribution Requirements. To maintain our qualification as a REIT,
we are required to distribute dividends (other than capital gain dividends) to
our stockholders in an amount at least equal to the sum of 95% of our "REIT
taxable income" (computed without regard to the dividends paid deduction and our
net capital gain) and 95% of our net income (after tax), if any, from
foreclosure property, minus the excess of the sum of certain items of noncash
income (i.e., income attributable to leveled stepped rents, original issue
discount on purchase money debt, or a like-kind exchange that is later
determined to be taxable) over 5% of "REIT taxable income" as described above.
 
     These distributions must be paid in the taxable year to which they relate,
or in the following taxable year if they are declared before we timely file our
tax return for such year and if paid on or before the first regular dividend
payment after such declaration. Except as provided below, these distributions
are taxable to our stockholders (other than tax-exempt entities, as discussed
below) in the year in which paid. This is so even though these distributions
relate to the prior year for purposes of our 95% distribution requirement. The
amount distributed must not be preferential -- e.g., every stockholder of the
class of stock to which a distribution is made must be treated the same as every
other stockholder of that class, and no class of stock may be treated otherwise
than in accordance with its dividend rights as a class. To the extent that we do
not distribute all of our net capital gain or distribute at least 95%, but less
than 100%, of our "REIT taxable income," as adjusted, we will be subject to tax
thereon at regular ordinary and capital gain corporate tax rates. We believe we
have made and intend to continue to make timely distributions sufficient to
satisfy these annual distribution requirements. In this regard, the Partnership
Agreement
 
                                       77
<PAGE>   81
 
authorizes us, as general partner of the Operating Partnership, to take such
steps as may be necessary to cause the Operating Partnership to distribute to
its partners an amount sufficient to permit us to meet these distribution
requirements.
 
     We expect that our REIT taxable income will be less than our cash flow due
to the allowance of depreciation and other non-cash charges in computing REIT
taxable income. Accordingly, we anticipate that we will generally have
sufficient cash or liquid assets to enable us to satisfy the distribution
requirements described above. However, from time to time, we may not have
sufficient cash or other liquid assets to meet these distribution requirements
due to timing differences between the actual receipt of income and actual
payment of deductible expenses, and the inclusion of income and deduction of
expenses in arriving at our taxable income. If these timing differences occur,
in order to meet the distribution requirements, we may need to arrange for
short-term, or possibly long-term, borrowings or need to pay dividends in the
form of taxable stock dividends.
 
     Under certain circumstances, we 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 our deduction for
dividends paid for the earlier year. Thus, we may be able to avoid being taxed
on amounts distributed as deficiency dividends. However, we will be required to
pay interest based upon the amount of any deduction taken for deficiency
dividends.
 
     Furthermore, we would be subject to a 4% excise tax on the excess of the
required distribution over the amounts actually distributed if we should fail to
distribute during each calendar year (or in the case of distributions with
declaration and record dates falling in the last three months of the calendar
year, by the end of January immediately following such year) at least the sum of
85% of our REIT ordinary income for such year, 95% of our REIT capital gain
income for the year and any undistributed taxable income from prior periods. Any
REIT taxable income and net capital gain on which this excise tax is imposed for
any year is treated as an amount distributed during that year for purposes of
calculating such tax.
 
     Earnings and Profits Distribution Requirement. In order to qualify as a
REIT, we cannot have at the end of any taxable year any undistributed "earnings
and profits" that are attributable to a "C corporation" taxable year (i.e., a
year in which a corporation is neither a REIT nor an S corporation). In
connection with our formation transactions, we succeeded to various tax
attributes of AMB Institutional Realty Advisors, Inc., AMB Current Income Fund,
Inc. ("CIF") and AMB Value Added Fund, Inc. ("VAF") (if the mergers of CIF and
VAF into AMB Institutional Realty Advisors, Inc. (the "Private REIT Mergers")
were treated as tax-free reorganizations under the Code), including any
undistributed C corporation earnings and profits of such corporations. If AMB
Institutional Realty Advisors, Inc. qualified as an S corporation for each year
in which its activities would have created earnings and profits, and each of CIF
and VAF qualified as a REIT during its existence and its merger into us was
treated as a tax-free reorganization under the Code, then those corporations
would not have any undistributed C corporation earnings and profits. If,
however, either CIF or VAF failed to qualify as a REIT throughout the duration
of its existence, or AMB Institutional Realty Advisors, Inc. failed to qualify
as an S corporation for any year in which its activities would have created
earnings and profits, then we would have acquired undistributed C corporation
earnings and profits that, if not distributed by us prior to the end of its
first taxable year, would prevent us from qualifying as a REIT.
 
                                       78
<PAGE>   82
 
     We believe that each of CIF and VAF qualified as a REIT throughout the
duration of its existence and that, in any event, neither CIF nor VAF had any
undistributed C corporation earnings and profits at the time of the applicable
Private REIT Merger. We believe that AMB Institutional Realty Advisors, Inc.
qualified as an S corporation since its 1989 taxable year and that its
activities prior to such year did not create any earnings and profits. In
addition, in connection with our initial public offering, counsel to CIF and VAF
rendered opinions with respect to the qualification of those corporations as
REITs for federal income tax purposes, and Latham & Watkins rendered an opinion
with respect to AMB Institutional Realty Advisors, Inc.'s status as an S
corporation for federal income tax purposes. Those opinions were based on
certain representations and assumptions. However, the IRS may contend otherwise
on a subsequent audit of AMB Institutional Realty Advisors, Inc., CIF or VAF.
 
FAILURE TO QUALIFY
 
     If we fail to qualify for taxation as a REIT in any taxable year, and the
relief provisions do not apply, we will be subject to tax (including any
applicable alternative minimum tax) on our taxable income at regular corporate
rates. Distributions to stockholders in any year in which we fail to qualify
will not be deductible by us and we will not be required to distribute any
amounts to our stockholders. As a result, our failure to qualify as a REIT would
reduce the cash available for distribution by us to our stockholders. In
addition, if we fail to qualify as a REIT, all distributions to stockholders
will be taxable as ordinary income to the extent of our current and accumulated
earnings and profits, and subject to certain limitations of the Code, corporate
distributees may be eligible for the dividends received deduction. Unless
entitled to relief under specific statutory provisions, we will also be
disqualified from taxation as a REIT for the four taxable years following the
year during which we lost our qualification. It is not possible to state whether
in all circumstances we would be entitled to this statutory relief.
 
TAX ASPECTS OF THE OPERATING PARTNERSHIP AND THE JOINT VENTURES
 
     General. Substantially all of our investments will be held indirectly
through the Operating Partnership. In addition, the Operating Partnership holds
certain of its investments indirectly through joint ventures. In general,
partnerships are "pass-through" entities which are not subject to federal income
tax. Rather, partners are allocated their proportionate shares of the items of
income, gain, loss, deduction and credit of a partnership, and are potentially
subject to tax thereon, without regard to whether the partners receive a
distribution from the partnership. We will include in our income our
proportionate share of the foregoing partnership items for purposes of the
various REIT income tests and in the computation of our REIT taxable income.
Moreover, for purposes of the REIT asset tests, we will include our
proportionate share of assets held by the Operating Partnership and joint
ventures. See "-- Taxation of the Company."
 
     Entity Classification. Our interests in the Operating Partnership and the
joint ventures involve special tax considerations, including the possibility of
a challenge by the IRS of the status of the Operating Partnership or a
partnership as a partnership (as opposed to an association taxable as a
corporation) for federal income tax purposes. If the Operating Partnership or a
partnership were treated as an association, it would be taxable as a corporation
and therefore be subject to an entity-level tax on its income. In such a
situation, the character of our assets and items of gross income would change
and preclude us from satisfying the asset tests and possibly the income tests
(see "-- Taxation of the Company -- Asset Tests" and "-- Income Tests"). This,
in turn, would prevent us from
 
                                       79
<PAGE>   83
 
qualifying as a REIT. See "-- Failure to Qualify" for a discussion of the effect
of our failure to meet these tests for a taxable year. In addition, a change in
the Operating Partnership's or a partnership's status for tax purposes might be
treated as a taxable event. If so, we might incur a tax liability without any
related cash distributions.
 
     Treasury Regulations that apply for tax periods beginning on or after
January 1, 1997 provide that a domestic business entity not otherwise classified
as a corporation and which has at least two members (an "Eligible Entity") may
elect to be taxed as a partnership for federal income tax purposes. Unless it
elects otherwise, an Eligible Entity in existence prior to January 1, 1997 will
have the same classification for federal income tax purposes that it claimed
under the entity classification Treasury Regulations in effect prior to this
date. In addition, an Eligible Entity which did not exist, or did not claim a
classification, prior to January 1, 1997, will be classified as a partnership
for federal income tax purposes unless it elects otherwise. The Operating
Partnership and each of our joint ventures intend to claim classification as a
partnership under the Final Regulations, and, as a result, we believe such
partnerships will be classified as partnerships for federal income tax purposes.
 
     Allocations of Operating Partnership Income, Gain, Loss and Deduction. The
Partnership Agreement provides for preferred distributions of cash and preferred
allocations of income to the Company with respect to its Series A Preferred
Units and to the holders of Series B Preferred Units. In addition, to the extent
the Company issues Series C Preferred Stock in exchange for AMB Property II
Series C Preferred Units, the Operating Partnership will issue Series C
Preferred Units to the Company, and the Partnership Agreement will be amended to
provide for similar preferred distributions of cash and preferred allocations of
income to the Company with respect to its Series C Preferred Units. As a
consequence, the Company will receive distributions from the Operating
Partnership and attributable to its other assets that we would use to pay
dividends on shares of Series A Preferred Stock and any shares of Series B
Preferred Stock or Series C Preferred Stock issued by the Company before any
other partner in the Operating Partnership (other than a holder of Series B
Preferred Units, if such units are not then held by the Company) receives a
distribution. In addition, if necessary, income will be specially allocated to
the Company, and losses will be allocated to the other partners of the Operating
Partnership, in amounts necessary to ensure that the balance in the capital
account of the Company will at all times be equal to or in excess of the amount
payable by the Company on the Series A Preferred Stock and any Series B
Preferred Stock or Series C Preferred Stock then issued by the Company upon
liquidation or redemption. As long as the Company does not hold the Series B
Preferred Units, similar preferred distributions and allocations will be made
for the benefit of the holders of such units. All remaining items of operating
income and loss will be allocated to the holders of common Units in proportion
to the number of Units or Performance Units held by each such unitholder. All
remaining items of gain or loss relating to the disposition of the Operating
Partnership's assets upon liquidation will be allocated first to the partners in
the amounts necessary, in general, to equalize the Company's and the limited
partners' per unit capital accounts, with any special allocation of gain to the
holders of Performance Units being offset by a reduction in the gain allocation
to the Company and unitholders which were Performance Investors. Certain limited
partners have agreed to guarantee debt of the Operating Partnership, either
directly or indirectly through an agreement to make capital contributions to the
Operating Partnership under limited circumstances. As a result of these
guarantees or contribution agreements, and notwithstanding the foregoing
discussion of allocations of income and loss of the Operating Partnership to
holders of common Units, such limited partners could under limited circumstances
be allocated a disproportionate
 
                                       80
<PAGE>   84
 
amount of net loss upon a liquidation of the Operating Partnership, which net
loss would have otherwise been allocable to the Company.
 
     If an allocation is not recognized for federal income tax purposes, the
item subject to the allocation will be reallocated in accordance with the
partners' interests in the partnership. This reallocation will be determined by
taking into account all of the facts and circumstances relating to the economic
arrangement of the partners with respect to such item. The Operating
Partnership's allocations of taxable income and loss are intended to comply with
the requirements of Section 704(b) of the Code and the Treasury Regulations
promulgated under this section of the Code.
 
     Tax Allocations with Respect to the Properties. Under Section 704(c) of the
Code, income, gain, loss and deduction attributable to appreciated or
depreciated property that is contributed to a partnership in exchange for an
interest in the partnership, must be allocated in a manner so that the
contributing partner is charged with the unrealized gain or benefits from the
unrealized loss associated with the property at the time of the contribution.
The amount of the unrealized gain or unrealized loss is generally equal to the
difference between the fair market value of contributed property at the time of
contribution and the adjusted tax basis of the property at the time of
contribution (a "Book-Tax Difference"). These 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. Moreover, subsequent to
the formation of the Operating Partnership, additional appreciated property has
been contributed to the Operating Partnership in exchange for interests in the
Operating Partnership. The Partnership Agreement requires that these allocations
be made in a manner consistent with Section 704(c) of the Code.
 
     In general, the partners of the Operating Partnership (including the
Company) which contributed assets having an adjusted tax basis less than their
fair market value at the time of contribution will be allocated depreciation
deductions for tax purposes which are lower than such deductions would have been
if determined on a pro rata basis. In addition, in the event of the disposition
of any of the contributed assets which have such a Book-Tax Difference, all
income attributable to such Book-Tax Difference generally will be allocated to
such contributing partners. These allocations will tend to eliminate the
Book-Tax Difference over the life of the Operating Partnership. However, the
special allocation rules of Section 704(c) do not always entirely eliminate the
Book-Tax Difference on an annual basis or with respect to a specific taxable
transaction such as a sale. Thus, the carryover basis of the contributed assets
in the hands of the Operating Partnership may cause the Company or other
partners to be allocated lower depreciation and other deductions, and possibly
an amount of taxable income in the event of a sale of such contributed assets in
excess of the economic or book income allocated to the Company or other partners
as a result of such sale. Such an allocation might cause the Company or other
partners to recognize taxable income in excess of cash proceeds, which might
adversely affect the Company's ability to comply with the REIT distribution
requirements. See "-- Taxation of the Company -- Requirements for Qualification"
and "-- Annual Distribution Requirements."
 
     Treasury Regulations issued under Section 704(c) of the Code provide
partnerships with a choice of several methods of accounting for Book-Tax
Differences, including retention of the "traditional method" or the election of
certain methods which would permit any distortions caused by a Book-Tax
Difference to be entirely rectified on an annual basis or with respect to a
specific taxable transaction such as a sale. We and the
 
                                       81
<PAGE>   85
 
Operating Partnership have determined to use the "traditional method" for
accounting for Book-Tax Differences for the properties initially contributed to
the Operating Partnership and for certain assets contributed subsequently. We
and the Operating Partnership have not yet decided what method will be used to
account for Book-Tax Differences for properties acquired by the Operating
Partnership in the future.
 
     Any property acquired by the Operating Partnership in a taxable transaction
will initially have a tax basis equal to its fair market value, and Section
704(c) of the Code will not apply.
 
TAXATION OF TAXABLE U.S. STOCKHOLDERS
 
     As used below, the term "U.S. Stockholder" means a holder of shares of
common stock who (for United States federal income tax purposes):
 
     - is a citizen or resident of the United States;
 
     - is a corporation, partnership, or other entity created or organized in or
       under the laws of the United States or of any state thereof or in the
       District of Columbia, unless, in the case of a partnership, Treasury
       Regulations provide otherwise;
 
     - is an estate the income of which is subject to United States federal
       income taxation regardless of its source; or
 
     - is a trust whose administration is subject to the primary supervision of
       a United States court and which has one or more United States persons who
       have the authority to control all substantial decisions of the trust.
 
     Notwithstanding the preceding sentence, to the extent provided in Treasury
Regulations, certain trusts in existence on August 20, 1996, and treated as
United States persons prior to this date that elect to continue to be treated as
United States persons, shall also be considered U.S. Stockholders.
 
     Distributions Generally. As long as we qualify as a REIT, distributions out
of our current or accumulated earnings and profits, other than capital gain
dividends discussed below, will constitute dividends taxable to our taxable U.S.
Stockholders as ordinary income. These distributions will not be eligible for
the dividends-received deduction in the case of U.S. Stockholders that are
corporations. For purposes of determining whether distributions to holders of
common stock are out of current or accumulated earnings and profits, our
earnings and profits will be allocated first to the outstanding preferred stock
(if any) and then to the common stock.
 
     To the extent that we make distributions in excess of our current and
accumulated earnings and profits, these distributions will be treated first as a
tax-free return of capital to each U.S. Stockholder. This treatment will reduce
the adjusted basis which each U.S. Stockholder has in his shares of stock for
tax purposes by the amount of the distribution (but not below zero).
Distributions in excess of a U.S. Stockholder's adjusted basis in his shares
will be taxable as capital gains (provided that the shares have been held as a
capital asset) and will be taxable as long-term capital gain if the shares have
been held for more than one year. Dividends we declare in October, November, or
December of any year and payable to a stockholder of record on a specified date
in any of these months shall be treated as both paid by us and received by the
stockholder on December 31 of that year, provided we actually pay the dividend
on or before January 31 of the following calendar year. Stockholders may not
include in their own income tax returns any of our net operating losses or
capital losses.
 
                                       82
<PAGE>   86
 
     Capital Gain Distributions. Distributions that we properly designate as
capital gain dividends will be taxable to taxable U.S. Stockholders as gains (to
the extent that they do not exceed our actual net capital gain for the taxable
year) from the sale or disposition of a capital asset. Depending on the period
of time we have held the assets which produced these gains, and on certain
designations, if any, which we may make, these gains may be taxable to
non-corporate U.S. stockholders at a 20% or 25% rate. U.S. Stockholders that are
corporations may, however, be required to treat up to 20% of certain capital
gain dividends as ordinary income. For a discussion of the manner in which that
portion of any dividends designated as capital gain dividends will be allocated
among the holders of our preferred stock and common stock, see "-- Description
of Capital Stock."
 
     Passive Activity Losses and Investment Interest Limitations. Distributions
we make and gain arising from the sale or exchange by a U.S. Stockholder of our
shares will not be treated as passive activity income. As a result, U.S.
Stockholders generally will not be able to apply any "passive losses" against
this income or gain. Distributions we make (to the extent they do not constitute
a return of capital) generally will be treated as investment income for purposes
of computing the investment interest limitation. Gain arising from the sale or
other disposition of our shares, however, will not be treated as investment
income under certain circumstances.
 
     Retention of Net Long-Term Capital Gains. We may elect to retain, rather
than distribute as a capital gain dividend, our net long-term capital gains. If
we make this election, we would pay tax on our retained net long-term capital
gains. In addition, to the extent we designate, a U.S. Stockholder generally
would:
 
     - include its proportionate share of our undistributed long-term capital
       gains in computing its long-term capital gains in its return for its
       taxable year in which the last day of our taxable year falls (subject to
       certain limitations as to the amount that is includable);
 
     - be deemed to have paid the capital gains tax imposed on us on the
       designated amounts included in the U.S. Stockholder's long-term capital
       gains;
 
     - receive a credit or refund for the amount of tax deemed paid by it;
 
     - increase the adjusted basis of its common stock by the difference between
       the amount of includable gains and the tax deemed to have been paid by
       it; and
 
     - in the case of a U.S. Stockholder that is a corporation, appropriately
       adjust its earnings and profits for the retained capital gains in
       accordance with Treasury Regulations to be prescribed by the IRS.
 
DISPOSITIONS OF COMMON STOCK
 
     If you are a U.S. Stockholder and you sell or dispose of your shares of
common stock, you will recognize gain or loss for federal income tax purposes in
an amount equal to the difference between the amount of cash and the fair market
value of any property you receive on the sale or other disposition and your
adjusted basis in the shares for tax purposes. This gain or loss will be capital
if you have held the common stock as a capital asset and will be long-term
capital gain or loss if you have held the common stock for more than one year.
However, if you are a U.S. Stockholder and you recognize loss upon the sale or
other disposition of common stock that you have held for six months or less
(after applying certain holding period rules), the loss you recognize will be
treated as a long-term capital loss, to the extent you received distributions
from us which were required to be treated as long-term capital gains.
                                       83
<PAGE>   87
 
BACKUP WITHHOLDING
 
     We report to our U.S. Stockholders and the IRS the amount of dividends paid
during each calendar year, and the amount of any tax withheld. Under the backup
withholding rules, a stockholder may be subject to backup withholding at the
rate of 31% with respect to dividends paid unless the holder is a corporation or
comes within certain other exempt categories and, when required, demonstrates
this fact, or provides a taxpayer identification number, certifies as to no loss
of exemption from backup withholding, and otherwise complies with applicable
requirements of the backup withholding rules. A U.S. Stockholder that does not
provide us with his correct taxpayer identification number may also be subject
to penalties imposed by the IRS. Backup withholding is not an additional tax.
Any amount paid as backup withholding will be creditable against the
stockholder's income tax liability. In addition, we may be required to withhold
a portion of capital gain distributions to any stockholders who fail to certify
their non-foreign status. See "-- Taxation of Non-U.S. Stockholders."
 
TAXATION OF TAX-EXEMPT STOCKHOLDERS
 
     The IRS has ruled that amounts distributed as dividends by a qualified REIT
do not constitute unrelated business taxable income ("UBTI") when received by a
tax-exempt entity. Based on that ruling, provided that a tax-exempt stockholder
(except certain tax-exempt stockholders described below) has not held its shares
as "debt financed property" within the meaning of the Code (generally, shares of
common stock, the acquisition of which was financed through a borrowing by the
tax exempt stockholder) and the shares are not otherwise used in a trade or
business, dividend income from us will not be UBTI to a tax-exempt stockholder.
Similarly, income from the sale of shares will not constitute UBTI unless a
tax-exempt stockholder has held its shares as "debt financed property" within
the meaning of the Code or has used the shares in its trade or business.
 
     For tax-exempt stockholders which are social clubs, voluntary employee
benefit associations, supplemental unemployment benefit trusts, and qualified
group legal services plans exempt from federal income taxation under Code
Section 501(c)(7), (c)(9), (c)(17) and (c)(20), respectively, income from an
investment in our shares will constitute UBTI unless the organization is able to
properly deduct amounts set aside or placed in reserve for certain purposes so
as to offset the income generated by its investment in our shares. These
prospective investors should consult their own tax advisors concerning these
"set aside" and reserve requirements.
 
     Notwithstanding the above, however, a portion of the dividends paid by a
"pension held REIT" shall be treated as UBTI as to certain types of trusts which
hold more than 10% (by value) of the interests in the REIT.
 
     A REIT will not be a "pension held REIT" if it is able to satisfy the "not
closely held" requirement without relying upon the "look-through" exception with
respect to certain trusts. As a result of certain limitations on the transfer
and ownership of stock contained in our charter, we do not expect to be
classified as a "pension held REIT," and, as a result, the tax treatment
described above should be inapplicable to our stockholders.
 
TAXATION OF NON-U.S. STOCKHOLDERS
 
     The preceding discussion does not address the rules governing United States
federal income taxation of the ownership and disposition of common stock by
persons that are not U.S. Stockholders ("Non-U.S. Stockholders"). In general,
Non-U.S. Stockholders may be subject to special tax withholding requirements on
distributions from the Company and
                                       84
<PAGE>   88
 
with respect to their sale or other disposition of common stock of the Company,
except to the extent reduced or eliminated by an income tax treaty between the
United States and the Non-U.S. Stockholder's country. A Non-U.S. Stockholder who
is a stockholder of record and is eligible for reduction or elimination of
withholding must file an appropriate form with the Company in order to claim
such treatment. Non-U.S. Stockholders should consult their own tax advisors
concerning the federal income tax consequences to them of an acquisition of
shares of Common Stock, including the federal income tax treatment of
dispositions of interests in, and the receipt of distributions from, the
Company.
 
OTHER TAX CONSEQUENCES
 
     We may be subject to state or local taxation in various state or local
jurisdictions, including those in which we transact business and our
stockholders may be subject to state or local taxation in various state or local
jurisdictions, including those in which they reside. Our state and local tax
treatment may not conform to the federal income tax consequences discussed
above. In addition, your state and local tax treatment may not conform to the
federal income tax consequences discussed above. Consequently, you should
consult your own tax advisors regarding the effect of state and local tax laws
on an investment in our shares.

                              ERISA CONSIDERATIONS
 
     The following is a summary of material considerations arising under the
Employee Retirement Income Securities Act of 1974, as amended ("ERISA") and the
prohibited transaction provisions of Section 4975 of the Code that may be
relevant to a prospective purchaser (including a prospective purchaser that is
not an employee benefit plan which is subject to ERISA, but is a tax-qualified
retirement plan or an individual retirement account, individual retirement
annuity, medical savings account or education individual retirement account
(collectively, an "IRA")). This discussion does not purport to deal with all
aspects of ERISA or Section 4975 of the Code or, to the extent not preempted,
state law that may be relevant to particular employee benefit plan stockholders
(including plans subject to Title I of ERISA, other employee benefit plans and
IRAs subject to the prohibited transaction provisions of Section 4975 of the
Code, and governmental plans and church plans that are exempt from ERISA and
Section 4975 of the Code but that may be subject to state law requirements) in
light of their particular circumstances.
 
     A FIDUCIARY MAKING THE DECISION TO INVEST IN SHARES OF COMMON STOCK ON
BEHALF OF A PROSPECTIVE PURCHASER WHICH IS AN ERISA PLAN, A TAX QUALIFIED
RETIREMENT PLAN, AN IRA OR OTHER EMPLOYEE BENEFIT PLAN IS ADVISED TO CONSULT ITS
OWN LEGAL ADVISOR REGARDING THE SPECIFIC CONSIDERATIONS ARISING UNDER ERISA,
SECTION 4975 OF THE INTERNAL REVENUE CODE, AND (TO THE EXTENT NOT PRE-EMPTED)
STATE LAW WITH RESPECT TO THE PURCHASE, OWNERSHIP OR SALE OF SHARES OF COMMON
STOCK BY SUCH PLAN OR IRA. Plans should also consider the entire discussion
under the heading "Certain Federal Income Tax Considerations," as material
contained in that section is relevant to any decision by an employee benefit
plan, tax-qualified retirement plan or IRA to purchase our common stock.
 
EMPLOYEE BENEFIT PLANS, TAX-QUALIFIED RETIREMENT PLANS AND IRAS
 
     Each fiduciary of an employee benefit plan subject to Title I of ERISA (an
"ERISA Plan") should carefully consider whether an investment in shares of
common stock is consistent with its fiduciary responsibilities under ERISA. In
particular, the fiduciary requirements of Part 4 of Title I of ERISA require
that
 
     - an ERISA Plan make investments that are prudent and in the best interests
       of the ERISA Plan, its participants and beneficiaries;
 
     - an ERISA Plan make investments that are diversified in order to reduce
       the risk of large losses, unless it is clearly prudent for the ERISA Plan
       not to do so;
 
     - an ERISA Plan's investments are authorized under ERISA and the terms of
       the governing documents of the ERISA Plan; and
 
     - the fiduciary not cause the ERISA Plan to enter into transactions
       prohibited under Section 406 of ERISA.
 
     In determining whether an investment in shares of common stock is prudent
for purposes of ERISA, the appropriate fiduciary of an ERISA Plan should
consider all of the facts and circumstances, including whether the investment is
reasonably designed, as a part of the ERISA Plan's portfolio for which the
fiduciary has investment responsibility, to meet the objectives of the ERISA
Plan, taking into consideration the risk of loss and opportunity for gain (or
other return) from the investment, the diversification, cash flow
 
                                       86
<PAGE>   90
 
and funding requirements of the ERISA Plan, and the liquidity and current return
of the ERISA Plan's portfolio. A fiduciary should also take into account the
nature of our business, the length of our operating history and other matters
described under "Risk Factors."
 
     The fiduciary of an IRA or of an employee benefit plan not subject to Title
I of ERISA because it is a governmental or church plan (if no election has been
made under Section 410(d) of the Code) or because it does not cover common law
employees (a "Non-ERISA Plan") should consider that such an IRA or Non-ERISA
Plan may only make investments that are either authorized or not prohibited by
the appropriate governing documents, not prohibited under Section 4975 of the
Code and permitted under applicable state law.
 
STATUS OF THE COMPANY UNDER ERISA
 
     A prohibited transaction may occur if our assets are deemed to be assets of
the investing ERISA Plans and disqualified persons deal with such assets. In
certain circumstances where an ERISA Plan holds an interest in an entity, the
assets of the entity are deemed to be ERISA Plan assets (the "look-through
rule"). Under those circumstances, any person that exercises authority or
control with respect to the management or disposition of the assets is an ERISA
Plan fiduciary. ERISA Plan assets are not defined in ERISA or the Code, but the
United States Department of Labor has issued regulations, effective March 13,
1987, that outline the circumstances under which an ERISA Plan's interest in an
entity will be subject to the look-through rule.
 
     The Department of Labor regulations apply only to the purchase by an ERISA
Plan of an "equity interest" in an entity, such as stock of a REIT. However, the
Department of Labor regulations provide an exception to the look-through rule
for equity interests that are "publicly-offered securities." The Department of
Labor regulations also provide exceptions to the look-through rule for equity
interests in certain types of entities, including any entity which qualifies as
either a "real estate operating company" (a "REOC") or a "venture capital
operating company" (a "VCOC").
 
     Under the Department of Labor regulations, a "publicly-offered security" is
a security that is:
 
     - freely transferable;
 
     - part of a class of securities that is widely-held; and
 
     - either part of a class of securities that is registered under section
       12(b) or 12(g) of the Exchange Act or sold to an ERISA Plan as part of an
       offering of securities to the public pursuant to an effective
       registration statement under the Securities Act and the class of
       securities of which such security is a part is registered under the
       Exchange Act within 120 days (or such longer period allowed by the SEC)
       after the end of the fiscal year of the issuer during which the offering
       of such securities to the public occurred.
 
     Whether a security is considered "freely transferable" depends on the facts
and circumstances of each case. Under the Department of Labor regulations, if
the security is part of an offering in which the minimum investment is $10,000
or less, then any restriction on or prohibition against any transfer or
assignment of such security for the purposes of preventing a termination or
reclassification of the entity for federal or state tax purposes will not
ordinarily prevent the security from being considered freely transferable.
Additionally, limitations or restrictions on the transfer or assignment of a
security which
                                       87
<PAGE>   91
 
are created or imposed by persons other than the issuer of the security or
persons acting for or on behalf of the issuer will ordinarily not prevent the
security from being considered freely transferable. A class of securities is
considered "widely-held" if it is a class of securities that is owned by 100 or
more investors independent of the issuer and of one another.
 
     Under the Department of Labor regulations, a REOC is defined as an entity
which on certain testing dates has at least 50% of its assets (other than
short-term investments pending long-term commitment or distribution to
investors), valued at cost, invested in real estate which is managed or
developed and with respect to which the entity has the right to substantially
participate directly in the management or development activities and which, in
the ordinary course of its business, is engaged directly in real estate
management or development activities. A VCOC is defined as an entity which on
certain testing dates has at least 50% of its assets (other than short-term
investments pending long-term commitment or distribution to investors), valued
at cost, invested in one or more operating companies with respect to which the
entity has management rights and which, in the ordinary course of its business,
actually exercises its management rights with respect to one or more of the
operating companies in which it invests.
 
     We expect that the shares of our common stock offered in this prospectus
will meet the criteria of the publicly-offered securities exception to the
look-through rule. First, the common stock should be considered to be freely
transferable, as the minimum investment will be less than $10,000 and the only
restrictions upon its transfer are those required under federal tax laws to
maintain our status as a REIT, resale restrictions under applicable federal
securities laws with respect to securities not purchased pursuant to this
prospectus and those owned by our officers, directors and other affiliates, and
voluntary restrictions agreed to by the selling stockholders regarding volume
limitations. See "Description of Certain Provisions of the Partnership Agreement
of the Operating Partnership -- Registration Rights." Second, we expect the
common stock to be held by 100 or more investors and we expect that at least 100
or more of these investors will be independent of us and of one another. Third,
the shares of common stock will be part of an offering of securities to the
public pursuant to an effective registration statement under the Securities Act
and the common stock is registered under the Exchange Act. In addition, we have
obtained management rights with respect to the Operating Partnership and conduct
our affairs in such a manner that we will qualify as either a REOC or VCOC under
the Department of Labor regulations. Accordingly, we believe that if an ERISA
Plan purchases the common stock, our assets should not be deemed to be ERISA
Plan assets and, therefore, that any person who exercises authority or control
with respect to our assets should not be an ERISA Plan fiduciary.

                              SELLING STOCKHOLDERS
 
     "Selling stockholders" are those persons who may receive shares of our
common stock registered pursuant to this registration statement upon exchange of
Units. The following table provides the names of the selling stockholders, the
maximum number of shares of common stock issuable to each of the selling
stockholders in the exchange and the aggregate number of shares of common stock
that will be owned by the selling stockholders after the exchange. The number of
shares on the following table represents the number of shares of common stock
into which Units held by the person are exchangeable. Since the selling
stockholders may sell all, some or none of their shares, we cannot estimate the
aggregate number of shares that the selling stockholders will offer pursuant to
this prospectus or that each selling stockholder will own upon completion of the
offering to which this prospectus relates.
 
     The selling stockholders named below may from time to time offer the shares
of common stock offered by this prospectus:

                              PLAN OF DISTRIBUTION
 
     This prospectus relates to:
 
     - the possible issuance by us of up to 2,542,163 shares of common stock if,
       and to the extent that, holders of up to 2,542,163 Units tender their
       Units for cash redemption and we elect, in our sole and absolute
       discretion, to exchange the Units for common stock in lieu of a cash
       redemption; and
 
     - the offer and sale from time to time of those 2,542,163 shares of common
       stock by the selling stockholders.
 
     We are registering the shares of common stock to provide the holders with
freely tradeable securities, but the registration of these shares does not
necessarily mean that any of these shares will be offered or sold by the
holders.
 
     Pursuant to the terms and conditions of the registration rights agreement
dated as of November 26, 1997 among the Company, the Operating Partnership and
the selling stockholders, prior to the date upon which the Units would be
eligible for resale under Rule 144(k) under the Securities Act, as such rule may
be amended from time to time (or any similar rule or regulation hereafter
adopted by the SEC), each of the selling stockholders generally is limited to
resales of any shares of common stock issued pursuant to this prospectus to the
number of shares which otherwise would be eligible for resale by that limited
partner pursuant to Rule 144, assuming the shares were issued on the same date
as the respective Units were issued. See "Risk Factors -- Ownership of Common
Stock -- The Large Number of Shares Available for Future Sale Could Adversely
Affect the Market Price of Our Common Stock."
 
     We will not receive any proceeds from the issuance of the shares of common
stock to the selling stockholders or from the sale of the shares by the selling
stockholders, but we have agreed to pay certain expenses of the registration of
the shares. The selling stockholders may from time to time sell the shares
directly to purchasers. Alternatively, the selling stockholders may from time to
time offer the shares through dealers or agents, who may receive compensation in
the form of commissions from the selling stockholders and for the purchasers of
the shares for whom they may act as agent. The selling stockholders and any
dealers or agents that participate in the distribution of the shares may be
deemed to be "underwriters" within the meaning of the Securities Act and any
profit on the sale of the common stock by them and any commissions received by
any such dealers or agents might be deemed to be underwriting commissions under
the Securities Act.
 
     In connection with distribution of the shares of common stock covered by
this prospectus, the selling stockholders may enter into hedging transactions
with broker-dealers, and the broker-dealers may engage in short sales of the
common stock in the course of hedging the positions they assume with the selling
stockholders. The selling stockholders also may sell the common stock short and
deliver the common stock to close out such short positions. The selling
stockholders also may enter into option or other transactions with
broker-dealers that involve the delivery of the shares to the broker-dealers,
who may then resell or otherwise transfer the shares. The selling stockholders
also may loan or pledge the shares to a broker-dealer and the broker-dealer may
sell the shares so loaned or upon a default may sell or otherwise transfer the
pledged shares.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 2-418 of the MGCL permits a corporation to indemnify its directors
and officers and certain other parties against judgments, penalties, fines,
settlements, and reasonable expenses actually incurred by them in connection
with any proceeding to which they may be made a party by reason of their service
in those or other capacities unless it is established that (i) the act or
omission of the director or officer was material to the matter giving rise to
the proceeding and (a) was committed in bad faith or (b) was the result of
active and deliberate dishonesty; (ii) the director or officer actually received
an improper personal benefit in money, property or services; or (iii) in the
case of any criminal proceeding, the director or officer had reasonable cause to
believe that the act or omission was unlawful. Indemnification may be made
against judgments, penalties, fines, settlements and reasonable expenses
actually incurred by the director or officer in connection with the proceeding;
provided, however, that if the proceeding is one by or in the right of the
corporation, indemnification may not be made with respect to any proceeding in
which the director or officer has been adjudged to be liable to the corporation.
In addition, a director or officer may not be indemnified with respect to any
proceeding charging improper personal benefit to the director or officer,
whether or not involving action in the director's or officer's official
capacity, in which the director or officer was adjudged to be liable on the
basis that personal benefit was received. The termination of any proceeding by
conviction, or upon a plea of nolo contendere or its equivalent, or an entry of
any order of probation prior to judgment, creates a rebuttable presumption that
the director or officer did not meet the requisite standard of conduct required
for indemnification to be permitted.
 
     In addition, Section 2-418 of the MGCL requires that, unless prohibited by
its charter, a corporation indemnify any director or officer who is made a party
to any proceeding by reason of service in that capacity against reasonable
expenses incurred by the director or officer in connection with the proceeding,
in the event that the director or officer is successful, on the merits or
otherwise, in the defense of the proceeding.

     The Company's Charter and Bylaws provide in effect for the indemnification
by the Company of the directors and officers of the Company to the fullest
extent permitted by applicable law. The Company has purchased directors' and
officers' liability insurance for the benefit of its directors and officers.
 
     The Company has entered into indemnification agreements with each of its
executive officers and directors. The indemnification agreements require, among
other matters, that the Company indemnify its executive officers and directors
to the fullest extent permitted by law and reimburse the executive officers and
directors for all related expenses as incurred, subject to return if it is
subsequently determined that indemnification is not permitted.

ITEM 17. UNDERTAKINGS
 
     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 facts 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;
 
            (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;
 
provided, however, that paragraphs (a)(i) and (a)(ii) 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 registrant pursuant to
Section 13 or 15(d) of the Securities Exchange Act of 1934 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.
 
                                      II-3
<PAGE>   99
 
        (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.
 
     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 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 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
herein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     The undersigned Registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given the
latest quarterly report that is specifically incorporated by reference in the
prospectus to provide such interim financial information.
 
     The undersigned Registrant hereby further undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance under Rule 430A and contained in
     a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4), or 497(h) under the Securities Act of 1933 shall be deemed to be part
     of this registration statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus 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.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended, may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, 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 Exchange Act of 1934, and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the 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, the 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 Exchange Act of 1934, and will be governed by the final adjudication
of such issue.

                           REDEEMABLE PREFERRED STOCK

        AMB Property Corporation, a corporation organized and existing under the
laws of the State of Maryland (the "Corporation"), certifies to the State
Department of Assessments and Taxation of Maryland (the "Department") that:

        FIRST: Pursuant to the authority expressly vested in the Board of
Directors of the Corporation (sometimes referred to herein as the "Board") by
Article IV of the Articles of Incorporation of the Corporation filed with the
Department on November 24, 1997, which comprises, together with the Articles
Supplementary filed by the Corporation on July 23, 1998 establishing a class of
Preferred Stock of the Corporation, par value $0.01 per share (the "Preferred
Stock"), designated as the "8 1/2% Series A Cumulative Redeemable Preferred
Stock" (the "Series A Preferred Stock") and these Articles Supplementary, the
charter (the "Charter") of the Corporation, and Section 2-105 of the Maryland
General Corporation Law (the "MGCL"), the Board of Directors of the Corporation,
on September 3, 1998, adopted resolutions authorizing the Corporation, among
other things, to issue up to a stated maximum number of shares of Preferred
Stock of the Corporation, having a stated maximum aggregate liquidation
preference and dividend rate and certain other stated terms applicable to the
issuance thereof, and appointing, pursuant to the MGCL and the powers contained
in the Bylaws of the Corporation, a committee (the "Committee") of the Board of
Directors comprised of Hamid R. Moghadam and delegating to the Committee, to the
fullest extent permitted by Maryland law and the Charter and Bylaws of the
Corporation, all powers of the Board of Directors with respect to classifying,
authorizing, approving, ratifying and/or confirming the terms of the Preferred
Stock to be issued, including, without limitation, the preferences, conversion
and other rights, voting powers, restrictions, limitations as to dividends and
other distributions, qualifications and terms and conditions of redemption, and
determining the consideration per share to be received in respect of the
issuance and sale of each share of Preferred Stock to be issued and sold, and
the number of shares of Preferred Stock to be so classified or reclassified and
issued by the Corporation, subject to the limitations set forth in the
resolutions of the Board of Directors adopted on September 3, 1998.

        SECOND:Pursuant to the authority conferred upon the Committee as
aforesaid, the Committee has, on November 11, 1998, adopted resolutions
classifying and designating a separate class of Preferred Stock as the 8 5/8%

Stock, with the preferences, conversions and other rights, voting powers,
restrictions, limitations as to dividends and other distributions,
qualifications and terms and conditions of redemption and other terms and
conditions of such 8 5/8% Series B Cumulative Redeemable Preferred Stock (within
the limitations set by the Board of Directors in the resolutions adopted on
September 3, 1998 and referred to in Article First of these Articles
Supplementary) and establishing 1,300,000 as the number of shares to be so
classified and designated, and authorizing the issuance of up to 1,300,000
shares of 8 5/8% Series B Cumulative Redeemable Preferred Stock.

        THIRD: The separate class of Preferred Stock of the Corporation created
by the resolutions duly adopted by the Board of Directors of the Corporation and
by the Committee and referred to in Articles First and Second of these Articles
Supplementary shall have the designation, number of shares, preferences,
conversion and other rights, voting powers, restrictions, limitations as to
dividends, qualifications, terms and conditions of redemption and other terms
and conditions as follows (and which, upon any restatement of the Charter, may
be made a part of Article IV thereof, with any necessary or appropriate changes
to the numeration or lettering of the sections or subsections hereof):

        (1) DESIGNATION AND NUMBER. A class of Preferred Stock, designated the
"8 5/8% Series B Cumulative Redeemable Preferred Stock" (the "Series B Preferred
Stock"), is hereby established. The number of shares of Series B Preferred Stock
shall be 1,300,000 (the "Series B Preferred Shares").

        (2) RANK. The Series B Preferred Shares will rank, with respect to
dividend rights and rights upon voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, (a) senior to all classes or
series of Common Stock (as defined in the Charter) and to all equity securities
of the Corporation the terms of which provide that such equity securities shall
rank junior to such Series B Preferred Shares; (b) on a parity with all equity
securities issued by the Corporation other than those referred to in clauses (a)
and (c) (including the Series A Preferred Stock); and (c) junior to all equity
securities issued by the Corporation which rank senior to the Series B Preferred
Shares in accordance with Section 6(d) of this Article Third. The term "equity
securities" does not include convertible debt securities.

        (3) DIVIDENDS.

        (a) Holders of Series B Preferred Shares shall be entitled to receive,
if, when and as authorized by the Board, out of funds legally available for the
payment of dividends, cumulative preferential cash dividends at the rate of 8
5/8% of the $50.00 liquidation preference per annum (equivalent to $4.3125 per
annum per share). Such dividends shall accumulate on a daily basis computed on
the basis of a 360-day year consisting of twelve 30-day months and be
cumulative, 



                                       2

<PAGE>   3


shall accrue from the original date of issuance and shall be payable quarterly
in equal amounts in arrears on the 15th day of each January, April, July and
October, or, if not a business day, the next succeeding business day (each a
"Dividend Payment Date"). Dividends shall be payable to holders of record as
they appear in the share records of the Corporation at the close of business on
the applicable record date (each, a "Dividend Record Date"), which shall be the
date designated by the Board for the payment of dividends that is not more than
30 nor less than 10 days prior to the applicable payment date therefor. Any
dividend payable on the Series B Preferred Shares for any partial dividend
period shall be prorated and computed on the basis of a 360-day year consisting
of twelve 30-day months. If any date on which distributions are to be made on
the Series B Preferred Stock is not a Business Day (as defined herein), then
payment of the distribution to be made on such date will be made on the next
succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay) except that, if such Business Day is in the next
succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date. Notwithstanding any provision to the contrary contained herein,
each outstanding share of Series B Preferred Stock shall be entitled to receive,
and shall receive, a dividend with respect to any Dividend Record Date equal to
the dividend paid with respect to each other share of Series B Preferred Stock
which is outstanding on such date. In addition, notwithstanding anything to the
contrary set forth herein, each share of Series B Preferred Stock shall also
continue to accrue all accrued and unpaid distributions up to the exchange date
on any Series B Preferred Unit (as defined in the Third Amended and Restated
Limited Partnership Agreement of AMB Property, L.P. dated as of November 12,
1998, as amended and supplemented from time to time (the "Partnership
Agreement")) validly exchanged into such share of Series B Preferred Stock in
accordance with the provisions of the Partnership Agreement.

        (b) No dividend on the Series B Preferred Shares shall be authorized by
the Board or be paid or set apart for payment by the Corporation at such time as
the terms and provisions of any agreement of the Corporation, including any
agreement relating to its indebtedness, prohibits such authorization, payment or
setting apart for payment or provides that such authorization, payment or
setting apart for payment would constitute a breach thereof, or a default
thereunder, or if such authorization or payment shall be restricted or
prohibited by law.

        (c) Notwithstanding anything to the contrary contained herein, dividends
on the Series B Preferred Shares shall accumulate whether or not restrictions
exist in respect thereof, whether or not there are funds legally available for
the payment thereof and whether or not such dividends are declared. Accumulated
but unpaid dividends on the Series B Preferred Shares will accumulate as of the
Dividend Payment Date on which they first become payable or on the date of
redemption, as the case may be.



                                       3

<PAGE>   4


        (d) If any Series B Preferred Shares are outstanding, no full dividends
will be declared or paid or set apart for payment on any other equity securities
of the Corporation of any other class or series ranking, as to distributions or
upon voluntary or involuntary liquidation, dissolution or winding up of the
Corporation, junior to or on a parity with the Series B Preferred Shares
(including the Series A Preferred Stock) unless full cumulative dividends have
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment thereof set apart for such payment on the Series B Preferred
Shares for all dividend periods. When dividends are not paid in full (or a sum
sufficient for such full payment is not so set apart) upon the Series B
Preferred Shares and any other equity securities ranking as to distributions on
a parity with the Series B Preferred Shares (including the Series A Preferred
Stock), all dividends declared upon the Series B Preferred Shares and any other
equity securities of the Corporation ranking on a parity with the Series B
Preferred Stock as to distributions and upon voluntary or involuntary
liquidation, dissolution or winding up of the Corporation (including the Series
A Preferred Stock) shall be declared pro rata so that the amount of dividends
declared per Series B Preferred Share and each such other equity securities
shall in all cases bear to each other the same ratio that accumulated dividends
per Series B Preferred Share and such other equity securities (which shall not
include any accumulation in respect of unpaid dividends for prior dividend
periods if such other equity securities do not have a cumulative dividend) bear
to each other. No interest, or sum of money in lieu of interest, shall be
payable in respect of any dividend payment or payments on Series B Preferred
Shares which may be in arrears.

        (e) Except as provided in the immediately preceding paragraph, unless
full cumulative dividends on the Series B Preferred Shares have been or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof is set apart for payment for all dividend periods, no dividends
(other than in Common Stock or other equity securities of the Corporation
ranking junior to the Series B Preferred Shares as to distributions and upon
voluntary or involuntary liquidation, dissolution and winding up of the
Corporation) shall be declared or paid or set aside for payment nor shall any
other dividend be declared or made upon the Common Stock or any other equity
securities of the Corporation ranking as to distributions or upon voluntary or
involuntary liquidation, dissolution or winding up of the Corporation junior to
or on a parity with the Series B Preferred Stock (including the Series A
Preferred Stock), nor shall any Common Stock or any other equity securities of
the Corporation ranking junior to or on a parity with the Series B Preferred
Stock as to distributions or upon voluntary or involuntary liquidation,
dissolution or winding up of the Corporation (including the Series A Preferred
Stock) be redeemed, purchased or otherwise acquired for any consideration (or
any monies be paid to or made available for a sinking fund for the redemption of
any such securities) by the Corporation (except by conversion into or exchange
for other equity securities of the Corporation ranking junior to the Series B
Preferred Stock as to distributions and upon voluntary and involuntary
liquidation, dissolution and winding up of the Corporation, and except 



                                       4

<PAGE>   5


pursuant to Section 7 of this Article Third to ensure the Corporation's
continued status as a REIT or comparable Charter provisions with respect to
other classes or series of the Corporation's stock).

        (f) Accumulated but unpaid dividends on the Series B Preferred Shares
will not bear interest and holders of Series B Preferred Shares shall not be
entitled to any dividend in excess of full cumulative dividends as described
above. Any dividend payment made on the Series B Preferred Shares shall first be
credited against the earliest accumulated but unpaid dividend due with respect
to such shares which remains payable.

        (g) If, for any taxable year, the Corporation elects to designate as a
"capital gain dividend" (as defined in Section 857 of the Code), any portion
(the "Capital Gains Amount") of the dividends paid or made available for the
year to holders of any class or series of stock of the Corporation, the portion
of the Capital Gains Amount that shall be allocable to holders of the Series B
Preferred Stock shall be the amount that the total dividends (as determined for
Federal income tax purposes) paid or made available to the holders of the Series
B Preferred Stock for the year bears to the aggregate amount of dividends (as
determined for Federal income tax purposes) paid or made available to the
holders of all classes or series of stock of the Corporation for such year.

        (4)  LIQUIDATION PREFERENCE.

        (a) In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, the holders of Series B Preferred
Shares then outstanding shall be entitled to receive out of the assets of the
Corporation legally available for distribution to its stockholders remaining
after payment or provision for payment of all debts and liabilities of the
Corporation, a liquidation preference in cash of $50.00 per share, plus an
amount equal to any accumulated and unpaid dividends to the date of such
payment, before any distribution of assets is made to holders of Common Stock or
any other equity securities of the Corporation that rank junior to the Series B
Preferred Shares as to liquidation rights.

        (b) If, upon any such voluntary or involuntary liquidation, dissolution
or winding up of the Corporation, the assets of the Corporation are insufficient
to make full payment to holders of Series B Preferred Shares and the
corresponding amounts payable on all shares of other classes or series of equity
securities of the Corporation ranking on a parity with the Series B Preferred
Shares as to liquidation rights (including the Series A Preferred Stock), then
the holders of the Series B Preferred Shares and all other such classes or
series of equity securities shall share ratably in any such distribution of
assets in proportion to the full liquidating distributions to which they would
otherwise be respectively entitled.



                                       5

<PAGE>   6


        (c) Written notice of any such liquidation, dissolution or winding up of
the Corporation, stating the payment date or dates when, and the place or places
where, the amounts distributable in such circumstances shall be payable, shall
be given by first class mail, postage pre-paid, not less than 30 nor more than
60 days prior to the payment date stated therein, to each record holder of the
Series B Preferred Shares at the respective addresses of such holders as the
same shall appear on the stock transfer records of the Corporation.

        (d) After payment of the full amount of the liquidating distributions to
which they are entitled, the holders of Series B Preferred Shares will have no
right or claim to any of the remaining assets of the Corporation.

        (e) The consolidation or merger of the Corporation with or into any
other entity, a merger of another entity with or into the Corporation, a
statutory share exchange by the Corporation or a sale, lease, transfer or
conveyance of all or substantially all of the property or business of the
Corporation shall not be deemed to constitute a liquidation, dissolution or
winding up of the Corporation.

        (f) In determining whether a distribution (other than upon voluntary or
involuntary liquidation, dissolution or winding up of the Corporation) by
dividend, redemption or other acquisition of shares of stock of the Corporation
or otherwise is permitted under the MGCL, no effect shall be given to amounts
that would be needed, if the Corporation were to be dissolved at the time of the
distribution, to satisfy the preferential rights upon dissolution of holders of
the Series B Preferred Shares whose preferential rights upon dissolution are
superior to those receiving the distribution.

        (5)  OPTIONAL REDEMPTION.

        (a) The Series B Preferred Shares are not redeemable prior to November
12, 2003. To ensure that the Corporation remains a qualified real estate
investment trust ("REIT") for federal income tax purposes, however, the Series B
Preferred Shares shall be subject to the provisions of Section 7 of this Article
Third pursuant to which Series B Preferred Shares owned by a stockholder in
excess of the Ownership Limit (as defined in Section 7 of this Article Third) or
certain other limitations shall automatically be transferred to a Trust for the
benefit of a Charitable Beneficiary (as defined in Section 7 of this Article
Third) and the Corporation shall have the right to purchase such shares, as
provided in Section 7 of this Article Third. On and after November 12, 2003, the
Corporation, at its option, upon giving notice as provided below, may redeem the
Series B Preferred Shares, in whole or from time to time in part, for cash, at a
redemption price of $50.00 per share, plus all accumulated and unpaid dividends
on such Series B Preferred Shares to the date fixed for redemption.



                                       6

<PAGE>   7


        (b) The redemption price of the Series B Preferred Shares (other than
any portion thereof consisting of accumulated and unpaid dividends) is payable
solely from the sale proceeds of other equity securities of the Corporation, and
not from any other source. For purposes of the preceding sentence, "equity
securities" means any equity securities (including Common Stock and Preferred
Stock (as defined in the Charter)), depositary shares in respect of any of the
foregoing, interests, participations or other ownership interests (however
designated) and any rights (other than debt securities convertible into or
exchangeable for equity securities) or options to purchase any of the foregoing.

        (c) If fewer than all of the outstanding Series B Preferred Shares are
to be redeemed, the shares to be redeemed shall be selected pro rata (as nearly
as practicable without creating fractional shares) or by lot or by any other
equitable method determined by the Corporation. If such redemption is to be by
lot and, as a result of such redemption, any holder of Series B Preferred Shares
would become a holder of a number of Series B Preferred Shares in excess of the
Ownership Limit (or other limitations set forth in Section 7 of this Article
Third) because such holder's Series B Preferred Shares were not redeemed, or
were only redeemed in part, then, except as otherwise provided in the Charter,
the Corporation will redeem the requisite number of Series B Preferred Shares of
such holder such that no holder will hold in excess of the Ownership Limit (or
such other limits) subsequent to such redemption.

        (d) Notwithstanding anything to the contrary contained herein, unless
full cumulative dividends on all Series B Preferred Shares shall have been or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof set apart for payment for all past dividend periods and the then
current dividend period, no Series B Preferred Shares shall be redeemed unless
all outstanding Series B Preferred Shares are simultaneously redeemed; provided,
however, that the foregoing shall not prevent the purchase by the Corporation of
Series B Preferred Shares pursuant to Section 7 of this Article Third or
otherwise in order to ensure that the Corporation remains qualified as a REIT
for Federal or state income tax purposes or the purchase or acquisition of
Series B Preferred Shares pursuant to a purchase or exchange offer made on the
same terms to holders of all outstanding Series B Preferred Shares. In addition,
unless full cumulative dividends on all outstanding Series B Preferred Shares
have been or contemporaneously are declared and paid or declared and a sum
sufficient for the payment thereof set apart for payment for all dividend
periods, the Corporation shall not purchase or otherwise acquire directly or
indirectly any Series B Preferred Shares or any equity securities of the
Corporation ranking junior to or on a parity with the Series B Preferred Shares
as to dividends or upon voluntary or involuntary liquidation, dissolution or
winding up of the Corporation (including the Series A Preferred Stock) (except
by conversion into or exchange for equity securities of the Corporation ranking
junior to the Series B Preferred Shares as to dividends and upon voluntary or
involuntary liquidation, dissolution or winding up of the 



                                       7

Corporation and except pursuant to Section 7 of this Article Third or comparable
Charter provisions with respect to other classes or series of the Corporation's
stock).

        (e) The holders of shares of Series B Preferred Stock at the close of
business on a Dividend Record Date will be entitled to receive the dividend
payable with respect to the shares of Series B Preferred Stock held on the
corresponding Dividend Payment Date notwithstanding the redemption thereof
between such Dividend Record Date and the corresponding Dividend Payment Date or
the Corporation's default in the payment of the dividend due. Except as provided
herein, the Corporation will make no payment or allowance for unpaid dividends,
whether or not in arrears, on Series B Preferred Shares to be redeemed.

        (f) The following provisions set forth the procedures for Redemption:

               (i) Notice of redemption will be given by publication in a
newspaper of general circulation in the City of New York, such publication to be
made once a week for two successive weeks commencing not less than 30 nor more
than 60 days prior to the redemption date. A similar notice will be mailed by
the Corporation, postage prepaid, not less than 30 nor more than 60 days prior
to the redemption date, addressed to the respective holders of record of the
Series B Preferred Shares to be redeemed at their respective addresses as they
appear on the share records of the Corporation. No failure to give such notice
or any defect therein or in the mailing thereof shall affect the validity of the
proceedings for the redemption of any Series B Preferred Shares except as to the
holder to whom notice was defective or not given.

               (ii) In addition to any information required by law or by the
applicable rules of any exchange upon which the Series B Preferred Shares may be
listed or admitted to trading, such notice shall state: (A) the redemption date;
(B) the redemption price; (C) the number of Series B Preferred Shares to be
redeemed; (D) the place or places where the certificates evidencing shares of
Series B Preferred Shares are to be surrendered for payment of the redemption
price; and (E) that dividends on the Series B Preferred Shares to be redeemed
will cease to accumulate on such redemption date. If fewer than all of the
Series B Preferred Shares held by any holder are to be redeemed, the notice
mailed to such holder shall also specify the number of Series B Preferred Shares
to be redeemed from such holder.

               (iii) On or after the redemption date, each holder of Series B
Preferred Shares to be redeemed shall present and surrender the certificates
representing such holder's Series B Preferred Shares to the Corporation at the
place designated in the notice of redemption and shall be entitled to the
redemption price and any accumulated and unpaid dividends payable upon such
redemption upon such surrender and thereupon the redemption price of such shares
(including all accumulated and unpaid dividends up to the redemption date) shall
be paid to or on the order of 



                                       8

<PAGE>   9


the person whose name appears on such certificate representing Series B
Preferred Shares as the owner thereof and each surrendered certificate shall be
canceled. If fewer than all the shares represented by any such certificate
representing Series B Preferred Shares are to be redeemed, a new certificate
shall be issued representing the unredeemed shares.

               (iv) If notice of redemption of any Series B Preferred Shares has
been given and if the funds necessary for such redemption have been set aside by
the Corporation in trust for the benefit of the holders thereof, then from and
after the redemption date all dividends on such Series B Preferred Shares shall
cease to accumulate and any such Series B Preferred Shares will no longer be
deemed outstanding and all rights of the holders thereof will terminate, except
the right to receive the redemption price (including all accumulated and unpaid
dividends up to the redemption date) and such shares shall not thereafter be
transferred (except with the consent of the Corporation) on the Corporation's
stock transfer records. At its election, the Corporation, prior to a redemption
date, may irrevocably deposit the redemption price (including accumulated and
unpaid dividends to the redemption date) of the Series B Preferred Shares so
called for redemption in trust for the holders thereof with a bank or trust
company, in which case the redemption notice to holders of the Series B
Preferred Shares to be redeemed shall (A) state the date of such deposit, (B)
specify the office of such bank or trust company as the place of payment of the
redemption price and (C) require such holders to surrender the certificates
representing such shares at such place on or about the date fixed in such
redemption notice (which may not be later than the redemption date) against
payment of the redemption price (including all accumulated and unpaid dividends
to the redemption date). Any monies so deposited which remain unclaimed by the
holders of the Series B Preferred Shares at the end of two years after the
redemption date shall be returned by such bank or trust company to the
Corporation.

        (g) Any Series B Preferred Shares that shall at any time have been
redeemed shall, after such redemption, have the status of authorized but
unissued Preferred Stock, without further designation as to series or class
until such shares are once more designated as part of a particular series or
class by the Board.

        (6)  VOTING RIGHTS.

        (a) Holders of the Series B Preferred Shares will not have any voting
rights, except as set forth below.

        (b) Whenever dividends on any Series B Preferred Shares shall remain
unpaid for six or more quarterly periods (whether or not consecutive) (a
"Preferred Dividend Default"), the holders of such Series B Preferred Shares
(voting as a single class with all other equity securities of the Corporation
ranking on a parity with the Series B Preferred Shares as to dividends and 



                                       9


<PAGE>   10


upon voluntary or involuntary liquidation, dissolution or winding up of the
Corporation upon which like voting rights have been conferred and are
exercisable, including the Series A Preferred Stock ("Parity Preferred Stock"))
will be entitled to vote for the election of two additional directors of the
Corporation (the "Preferred Stock Directors"), who will be elected for a
one-year term and until their successors are duly elected and shall qualify (or
until such director's right to hold such office terminates as provided herein,
whichever occurs earlier, subject to such director's earlier death,
disqualification, resignation or removal), at a special meeting called by the
holders of at least 20% of the outstanding Series B Preferred Shares or the
holders of shares of any other class or series of Parity Preferred Stock with
respect to which dividends are so unpaid (unless such request is received less
than 90 days before the date fixed for the next annual or special meeting of
stockholders) or, if the request for a special meeting is received by the
Corporation less than 90 days before the date fixed for the next annual or
special meeting of stockholders, at the next annual or special meeting of
stockholders, and at each subsequent annual meeting until all dividends
accumulated on the Series B Preferred Shares for all past dividend periods and
the dividend for the then current dividend period shall have been fully paid or
declared and a sum sufficient for the payment thereof set aside for payment in
full.

        (c) If and when all accumulated dividends and the dividend for the then
current dividend period on the Series B Preferred Shares shall have been paid in
full or declared by the Corporation and set aside for payment in full, the
holders of Series B Preferred Shares shall be divested of the voting rights set
forth in Section 6(b) of this Article Third (subject to revesting in the event
of each and every Preferred Dividend Default) and, if all accumulated dividends
have been paid in full or declared by the Corporation and set aside for payment
in full on all other classes or series of Parity Preferred Stock upon which like
voting rights have been conferred and are exercisable, the term of office of
each Preferred Stock Director so elected shall forthwith terminate. Any
Preferred Stock Director elected by the holders of Series B Preferred Shares and
any other such Parity Preferred Shares may be removed at any time with or
without cause by the vote of, and shall not be removed otherwise than by the
vote of, the holders of a majority of the outstanding Series B Preferred Shares
when they only have the voting rights set forth, or like those set forth, in
Section 6(b) of this Article Third, and by the majority vote of the Series B
Preferred Shares and all other classes or series of Parity Preferred Stock upon
which like voting rights have been conferred and are exercisable (voting as a
single class) when the Series B Preferred Shares and such Parity Preferred Stock
is entitled to vote thereon. So long as a Preferred Dividend Default shall
continue, any vacancy in the office of a Preferred Stock Director so elected may
be filled by written consent of the Preferred Stock Director so elected
remaining in office or, if none remains in office, by a vote of the holders of a
majority of the outstanding Series B Preferred Shares when they only have the
voting rights set forth, or like those set forth, in Section 6(b) of this
Article Third, and by the majority vote of the Series B Preferred Shares and
other classes or series of Parity Preferred Stock upon which like voting 



                                       10

<PAGE>   11

rights have been conferred and are exercisable (voting as a single class) when
the Series B Preferred Shares and such Parity Preferred Stock is entitled to
vote thereon.

        (d) So long as any Series B Preferred Stock remains outstanding, the
Corporation shall not, without the affirmative vote of the holders of at least
two-thirds of the Series B Preferred Stock outstanding at the time (i) authorize
or create, or increase the authorized or issued amount of, any class or series
of shares ranking senior to the Series B Preferred Stock with respect to payment
of distributions or rights upon liquidation, dissolution or winding-up or
reclassify any authorized shares of the Corporation into any such shares, or
create, authorize or issue any obligations or security convertible into or
evidencing the right to purchase any such shares, (ii) designate or create, or
increase the authorized or issued amount of, any Parity Preferred Stock or
reclassify any authorized shares of the Corporation into any such shares, or
create, authorize or issue any obligations or security convertible into or
evidencing the right to purchase any such shares, but only to the extent such
Parity Preferred Stock is issued to an affiliate of the Corporation, or (iii)
either (A) consolidate, merge into or with, or convey, transfer or lease its
assets substantially as an entirety, to any corporation or other entity, or (B)
amend, alter or repeal the provisions of the Corporation's Charter (including
these Articles Supplementary) or Bylaws, whether by merger, consolidation or
otherwise, in each case that would materially and adversely affect the powers,
special rights, preferences, privileges or voting power of the Series B
Preferred Stock or the holders thereof; provided, however, that with respect to
the occurrence of any event set forth in (iii) above, so long as (a) the
Corporation is the surviving entity and the Series B Preferred Stock remains
outstanding with the terms thereof unchanged, or (b) the resulting, surviving or
transferee entity is a corporation organized under the laws of any state and
substitutes the Series B Preferred Stock for other preferred stock having
substantially the same terms and same rights as the Series B Preferred Stock,
including with respect to distributions, voting rights and rights upon
liquidation, dissolution or winding-up, then the occurrence of any such event
shall not be deemed materially and adversely affect such rights, privileges or
voting powers of the holders of the Series B Preferred Stock and provided
further that any increase in the amount of authorized Preferred Stock or the
creation or issuance of any other class or series of Preferred Stock, or any
increase in an amount of authorized shares of each class or series, in each case
ranking either (a) junior to the Series B Preferred Stock with respect to
payment of distributions or the distribution of assets upon liquidation,
dissolution or winding-up, or (b) on a parity with the Series B Preferred Stock
with respect to payment of distributions or the distribution of assets upon
liquidation, dissolution or winding-up to the extent such Preferred Stock is not
issued to an affiliate of the Corporation, shall not be deemed to materially and
adversely affect such rights, preferences, privileges or voting powers.

        (e) The foregoing voting provisions shall not apply if, at or prior to
the time when the act with respect to which such vote would otherwise be
required shall be effected, all outstanding 



                                       11

                Supplementary, no Person shall Beneficially Own Series B

<PAGE>   15


                        (B) except as provided in Section 7(i) of these Articles
                Supplementary, no Person shall Constructively Own Series B
                Preferred Stock which, taking into account any other capital
                stock of the Corporation Constructively Owned by such Person,

                        (C) no Person shall Beneficially or Constructively Own
                Series B Preferred Stock which, taking into account any other
                capital stock of the Corporation Beneficially or Constructively
                Owned by such Person, would result in the Corporation being
                "closely held" within the meaning of Section 856(h) of the Code,
                or otherwise failing to qualify as a REIT (including but not
                limited to Beneficial or Constructive Ownership that would
                result in the Corporation owning (actually or Constructively) an
                interest in a tenant that is described in Section 856(d)(2)(B)
                of the Code if the income derived by the Corporation (either
                directly or indirectly through one or more partnerships or
                limited liability companies) from such tenant would cause the
                Corporation to fail to satisfy any of the gross income
                requirements of Section 856(c) of the Code or comparable
                provisions of state law).

                (ii) If, prior to the Restriction Termination Date, any Transfer
or other event occurs that, if effective, would result in any Person
Beneficially or Constructively Owning Series B Preferred Stock in violation of
Section 7(b)(i) of these Articles Supplementary, (1) then that number of shares
of Series B Preferred Stock that otherwise would cause such Person to violate
Section 7(b)(i) of these Articles Supplementary (rounded up to the nearest whole
share) shall be automatically transferred to a Trust for the benefit of a
Charitable Beneficiary, as described in Section 7(c), effective as of the close
of business on the business day prior to the date of such Transfer or other
event, and such Purported Beneficial Transferee shall thereafter have no rights
in such shares or (2) if, for any reason, the transfer to the Trust described in
clause (1) of this sentence is not automatically effective as provided therein
to prevent any Person from Beneficially or Constructively Owning Series B
Preferred Stock in violation of Section 7(b)(i) of these Articles Supplementary,
then the Transfer of that number of shares of Series B Preferred Stock that
otherwise would cause any Person to violate Section 7(b)(i) shall be void ab
initio, and the Purported Beneficial Transferee shall have no rights in such
shares.

                (iii) Subject to Section 7(n) of this Article Third and
notwithstanding any other provisions contained herein, prior to the Restriction
Termination Date, any Transfer of Series B Preferred Stock that, if effective,
would result in the capital stock of the Corporation being beneficially owned by
less than 100 Persons (determined without reference to any rules of attribution)
shall be void ab initio, and the intended transferee shall acquire no rights in
such Series B Preferred Stock.

provided in Section 17.8 of the Partnership Agreement. Notwithstanding any of
the provisions of the Partnership Agreement to the contrary, a partner of the
Operating Partnership shall not be entitled to effect an exchange of an interest
in the Operating Partnership for Series B Preferred Stock if the actual or
beneficial or Beneficial or Constructive Ownership of Series B Preferred Stock
would be prohibited under the provisions of this Section 7.

        (c)     Transfers of Series B Preferred Stock in Trust.

                (i) Upon any purported Transfer or other event described in
Section 7(b)(ii) of these Articles Supplementary, such Series B Preferred Stock
shall be deemed to have been transferred to the Trustee in his capacity as
trustee of a Trust for the exclusive benefit of one or more Charitable
Beneficiaries. Such transfer to the Trustee shall be deemed to be effective as
of the close of business on the business day prior to the purported Transfer or
other event that results in a transfer to the Trust pursuant to Section
7(b)(ii). The Trustee shall be appointed by the Corporation and shall be a
Person unaffiliated with the Corporation, any Purported Beneficial Transferee,
or any Purported Record Transferee. Each Charitable Beneficiary shall be
designated by the Corporation as provided in Section 7(c)(vi) of these Articles
Supplementary.

                (ii) Series B Preferred Stock held by the Trustee shall be
issued and outstanding Series B Preferred Stock of the Corporation. The
Purported Beneficial Transferee or Purported Record Transferee shall have no
rights in the shares of Series B Preferred Stock held by the Trustee. The
Purported Beneficial Transferee or Purported Record Transferee shall not benefit
economically from ownership of any shares held in trust by the Trustee, shall
have no rights to dividends and shall not possess any rights to vote or other
rights attributable to the shares of Series B Preferred Stock held in the Trust.

                (iii) The Trustee shall have all voting rights and rights to
dividends with respect to Series B Preferred Stock held in the Trust, which
rights shall be exercised for the exclusive benefit of the Charitable
Beneficiary. Any dividend or distribution paid prior to the discovery by the
Corporation that shares of Series B Preferred Stock have been transferred to the
Trustee shall be paid to the Trustee upon demand, and any dividend or
distribution declared but unpaid shall be paid when due to the Trustee with
respect to such Series B Preferred Stock. Any dividends or distributions so paid
over to the Trustee shall be held in trust for the Charitable Beneficiary.

                The Purported Record Transferee and Purported Beneficial
Transferee shall have no voting rights with respect to the Series B Preferred
Stock held in the Trust and, subject to 



                                       16

<PAGE>   17


Maryland law, effective as of the date the Series B Preferred Stock has been
transferred to the Trustee, the Trustee shall have the authority (at the
Trustee's sole discretion) (i) to rescind as void any vote cast by a Purported
Record Transferee with respect to such Series B Preferred Stock prior to the
discovery by the Corporation that the Series B Preferred Stock has been
transferred to the Trustee and (ii) to recast such vote in accordance with the
desires of the Trustee acting for the benefit of the Charitable Beneficiary;
provided, however, that if the Corporation has already taken irreversible
corporate action, then the Trustee shall not have the authority to rescind and
recast such vote. Notwithstanding any other provision of these Articles
Supplementary to the contrary, until the Corporation has received notification
that the Series B Preferred Stock has been transferred into a Trust, the
Corporation shall be entitled to rely on its share transfer and other
stockholder records for purposes of preparing lists of stockholders entitled to
vote at meetings, determining the validity and authority of proxies and
otherwise conducting votes of stockholders.

                (iv) Within 20 days of receiving notice from the Corporation
that shares of Series B Preferred Stock have been transferred to the Trust, the
Trustee of the Trust shall sell the shares of Series B Preferred Stock held in
the Trust to a Person, designated by the Trustee, whose ownership of the shares
of Series B Preferred Stock will not violate the ownership limitations set forth
in Section 7(b)(i). Upon such sale, the interest of the Charitable Beneficiary
in the shares of Series B Preferred Stock sold shall terminate and the Trustee
shall distribute the net proceeds of the sale to the Purported Record Transferee
and to the Charitable Beneficiary as provided in this Section 7(c)(iv). The
Purported Record Transferee shall receive the lesser of (1) the price paid by
the Purported Record Transferee for the shares of Series B Preferred Stock in
the transaction that resulted in such transfer to the Trust (or, if the event
which resulted in the transfer to the Trust did not involve a purchase of such
shares of Series B Preferred Stock at Market Price, the Market Price of such
shares of Series B Preferred Stock on the day of the event which resulted in the
transfer of such shares of Series B Preferred Stock to the Trust) and (2) the
price per share received by the Trustee (net of any commissions and other
expenses of sale) from the sale or other disposition of the shares of Series B
Preferred Stock held in the Trust. Any net sales proceeds in excess of the
amount payable to the Purported Record Transferee shall be immediately paid to
the Charitable Beneficiary together with any dividends or other distributions
thereon. If, prior to the discovery by the Corporation that shares of such
Series B Preferred Stock have been transferred to the Trustee, such shares of
Series B Preferred Stock are sold by a Purported Record Transferee then (i) such
shares of Series B Preferred Stock shall be deemed to have been sold on behalf
of the Trust and (ii) to the extent that the Purported Record Transferee
received an amount for such shares of Series B Preferred Stock that exceeds the
amount that such Purported Record Transferee was entitled to receive pursuant to
this Section 7(c)(iv), such excess shall be paid to the Trustee upon demand.

<PAGE>   18


                (v) Series B Preferred Stock transferred to the Trustee shall be
deemed to have been offered for sale to the Corporation, or its designee, at a
price per share equal to the lesser of (i) the price paid by the Purported
Record Transferee for the shares of Series B Preferred Stock in the transaction
that resulted in such transfer to the Trust (or, if the event which resulted in
the transfer to the Trust did not involve a purchase of such shares of Series B
Preferred Stock at Market Price, the Market Price of such shares of Series B
Preferred Stock on the day of the event which resulted in the transfer of such
shares of Series B Preferred Stock to the Trust) and (ii) the Market Price on
the date the Corporation, or its designee, accepts such offer. The Corporation
shall have the right to accept such offer until the Trustee has sold the shares
of Series B Preferred Stock held in the Trust pursuant to Section 7(c)(iv). Upon
such a sale to the Corporation, the interest of the Charitable Beneficiary in
the shares of Series B Preferred Stock sold shall terminate and the Trustee
shall distribute the net proceeds of the sale to the Purported Record Transferee
and any dividends or other distributions held by the Trustee with respect to
such Series B Preferred Stock shall thereupon be paid to the Charitable
Beneficiary.

                (vi) By written notice to the Trustee, the Corporation shall
designate one or more nonprofit organizations to be the Charitable Beneficiary
of the interest in the Trust such that the Series B Preferred Stock held in the
Trust would not violate the restrictions set forth in Section 7(b)(i) in the
hands of such Charitable Beneficiary.

        (d)     Remedies For Breach. If the Board of Directors or a committee
thereof or other designees if permitted by the MGCL shall at any time determine
in good faith that a Transfer or other event has taken place in violation of
Section 7(b) of these Articles Supplementary or that a Person intends to
acquire, has attempted to acquire or may acquire beneficial ownership
(determined without reference to any rules of attribution), Beneficial Ownership
or Constructive Ownership of any shares of Series B Preferred Stock of the
Corporation in violation of Section 7(b) of these Articles Supplementary, the
Board of Directors or a committee thereof or other designees if permitted by the
MGCL shall take such action as it deems advisable to refuse to give effect or to
prevent such Transfer, including, but not limited to, causing the Corporation to
redeem shares of Series B Preferred Stock, refusing to give effect to such
Transfer on the books of the Corporation or instituting proceedings to enjoin
such Transfer; provided, however, that any Transfers (or, in the case of events
other than a Transfer, ownership or Constructive Ownership or Beneficial
Ownership) in violation of Section 7(b)(i) of these Articles Supplementary,
shall automatically result in the transfer to a Trust as described in Section
7(b)(ii) and any Transfer in violation of Section 7(b)(iii) shall automatically
be void ab initio irrespective of any action (or non-action) by the Board of
Directors.

        (e)     Notice of Restricted Transfer. Any Person who acquires or
attempts to acquire shares of Series B Preferred Stock in violation of Section
7(b) of these Articles Supplementary, 



                                       18


<PAGE>   19


or any Person who is a Purported Beneficial Transferee such that an automatic
transfer to a Trust results under Section 7(b)(ii) of these Articles
Supplementary, shall immediately give written notice to the Corporation of such
event and shall provide to the Corporation such other information as the
Corporation may request in order to determine the effect, if any, of such
Transfer or attempted Transfer on the Corporation's status as a REIT.

        (f)     Owners Required To Provide Information. Prior to the Restriction
Termination Date each Person who is a beneficial owner or Beneficial Owner or
Constructive Owner of Series B Preferred Stock and each Person (including the
shareholder of record) who is holding Series B Preferred Stock for a beneficial
owner or Beneficial Owner or Constructive Owner shall provide to the Corporation
such information that the Corporation may request, in good faith, in order to
determine the Corporation's status as a REIT.

        (g)     Remedies Not Limited. Nothing contained in these Articles
Supplementary (but subject to Section 7(n) of these Articles Supplementary)
shall limit the authority of the Board of Directors to take such other action as
it deems necessary or advisable to protect the Corporation and the interests of
its shareholders by preservation of the Corporation's status as a REIT.

        (h)     Ambiguity. In the case of an ambiguity in the application of any
of the provisions of this Section 7 of these Articles Supplementary, including
any definition contained in Section 7(a), the Board of Directors shall have the
power to determine the application of the provisions of this Section 7 with
respect to any situation based on the facts known to it (subject, however, to
the provisions of Section 7(n) of these Articles Supplementary). In the event
Section 7 requires an action by the Board of Directors and these Articles
Supplementary fail to provide specific guidance with respect to such action, the
Board of Directors shall have the power to determine the action to be taken so
long as such action is not contrary to the provisions of Section 7. Absent a
decision to the contrary by the Board of Directors (which the Board may make in
its sole and absolute discretion), if a Person would have (but for the remedies
set forth in Section 7(b)) acquired Beneficial or Constructive Ownership of
Series B Preferred Stock in violation of Section 7(b)(i), such remedies (as
applicable) shall apply first to the shares of Series B Preferred Stock which,
but for such remedies, would have been actually owned by such Person, and second
to shares of Series B Preferred Stock which, but for such remedies, would have
been Beneficially Owned or Constructively Owned (but not actually owned) by such
Person, pro rata among the Persons who actually own such shares of Series B
Preferred Stock based upon the relative number of the shares of Series B
Preferred Stock held by each such Person.

        (i)     Exceptions.

                (i) Subject to Section 7(b)(i)(C), the Board of Directors, in
its sole discretion, may exempt a Person from the limitation on a Person
Beneficially Owning shares of Series B Preferred Stock in violation of Section
7(b)(i)(A) if the Board of Directors obtains any representations and
undertakings from such Person as are reasonably necessary in the opinion of the
Board of Directors to ascertain that no individual's Beneficial Ownership of
such shares of Series B Preferred Stock will violate Section 7(b)(i)(A) or that
any such violation will not cause the Corporation to fail to qualify as a REIT
under the Code, and that any violation of such representations or undertakings
(or other action which is contrary to the restrictions contained in Section 7(b)
of these Articles Supplementary) or attempted violation will result in such
Series B Preferred Stock being transferred to a Trust in accordance with Section
7(b)(ii) of these Articles Supplementary.

                (ii) Subject to Section 7(b)(i)(C), the Board of Directors, in
its sole discretion, may exempt a Person from the limitation on a Person
Constructively Owning Series B Preferred Stock in violation of Section
7(b)(i)(B), if the Corporation obtains any representations and undertakings from
such Person as are reasonably necessary in the opinion of the Board of Directors
to ascertain that such Person does not and will not own, actually or
Constructively, an interest in a tenant of the Corporation (or a tenant of any
entity owned in whole or in part by the Corporation) that would cause the
Corporation to own, actually or Constructively, more than a 9.8% interest (as
set forth in Section 856(d)(2)(B) of the Code) in such tenant and that any
violation or attempted violation will result in such Series B Preferred Stock
being transferred to a Trust in accordance with Section 7(b)(ii) of these
Articles Supplementary. Notwithstanding the foregoing, the inability of a Person
to make the certification described in this Section 7(i)(ii) shall not prevent
the Board of Directors, in its sole discretion, from exempting such Person from
the limitation on a Person Constructively Owning Series B Preferred Stock in
violation of Section 7(b)(i)(B) if the Board of Directors determines that the
resulting application of Section 856(d)(2)(B) of the Code would affect the
characterization of less than 0.5% of the gross income (as such term is used in
Section 856(c)(2) of the Code) of the Corporation in any taxable year, after
taking into account the effect of this sentence with respect to all other
capital stock of the Corporation to which this sentence applies.

                (iii) Prior to granting any exception pursuant to Section
7(i)(i) or (ii) of these Articles Supplementary, the Board of Directors may
require a ruling from the Internal Revenue Service, or an opinion of counsel, in
either case in form and substance satisfactory to the Board of Directors in its
sole discretion, as it may deem necessary or advisable in order to determine or
ensure the Corporation's status as a REIT.

        BENEFICIALLY OWN SHARES OF THE CORPORATION'S SERIES B PREFERRED STOCK
        WHICH, TAKING INTO ACCOUNT ANY OTHER CAPITAL STOCK OF THE CORPORATION

        AMB Property Corporation, a corporation organized and existing under the
laws of the State of Maryland (the "Corporation"), certifies to the State
Department of Assessments and Taxation of Maryland (the "Department") that:

        FIRST: Pursuant to the authority expressly vested in the Board of
Directors of the Corporation (sometimes referred to herein as the "Board") by
Article IV of the Articles of Incorporation of the Corporation filed with the
Department on November 24, 1997, which comprises, together with the Articles

<PAGE>   2

and referred to in Article First of these Articles Supplementary) and
establishing 2,200,000 as the number of shares to be so classified and
designated, and authorizing the issuance of up to 2,200,000 shares of 8.75%
Series C Cumulative Redeemable Preferred Stock.

        THIRD: The separate class of Preferred Stock of the Corporation created
by the resolutions duly adopted by the Board of Directors of the Corporation and
by the Committee and referred to in Articles First and Second of these Articles
Supplementary shall have the designation, number of shares, preferences,
conversion and other rights, voting powers, restrictions, limitations as to
dividends, qualifications, terms and conditions of redemption and other terms
and conditions as follows (and which, upon any restatement of the Charter, may
be made a part of Article IV thereof, with any necessary or appropriate changes
to the numeration or lettering of the sections or subsections hereof):

        (1) DESIGNATION AND NUMBER. A class of Preferred Stock, designated the
"8.75% Series C Cumulative Redeemable Preferred Stock" (the "Series C Preferred
Stock"), is hereby established. The number of shares of Series C Preferred Stock
shall be 2,200,000 (the "Series C Preferred Shares").

        (2) RANK. The Series C Preferred Shares will rank, with respect to
dividend rights and rights upon voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, (a) senior to all classes or
series of Common Stock (as defined in the Charter) and to all equity securities
of the Corporation the terms of which provide that such equity securities shall
rank junior to such Series C Preferred Shares; (b) on a parity with the Series A
Preferred Stock and Series B Preferred Stock and all equity securities issued by
the Corporation other than those referred to in clauses (a) and (c) (it being
the intent of the Corporation that the Series C Preferred Stock be on a parity
with the Series A Preferred Stock and the Series B Preferred Stock with respect
to dividend rights and rights upon voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, notwithstanding any provision
contained in these Articles Supplementary, which, if given effect, would make
the Series C Preferred Stock not in parity with the Series A Preferred Stock and
the Series B Preferred Stock; and any such provision contained in these Articles
Supplementary shall be of no force or effect); and (c) junior to all equity
securities issued by the Corporation which rank senior to the Series C Preferred
Shares in accordance with Section 6(d) of this Article Third. The term "equity
securities" does not include convertible debt securities, until the same are
converted into equity securities.

        (3) DIVIDENDS.

        (a) Holders of Series C Preferred Shares shall be entitled to receive,
if, when and as authorized by the Board, out of funds legally available for the
payment of dividends, cumulative preferential cash dividends at the rate of
8.75% of the $50.00 liquidation preference per annum (equivalent to $4.375 per
annum per share). Such dividends shall accumulate on a daily basis computed on
the basis of a 360-day year consisting of twelve 30-day months and be
cumulative, shall accrue from the original date of issuance and shall be payable
quarterly (such quarterly periods for purposes of payment and accrual will be
the quarterly periods ending on the dates specified in this sentence and not
calendar year quarters) in equal amounts in arrears on the 15th day of each
January, April, July and October, or, if not a business day, the next succeeding
business day (each a "Dividend Payment Date"). Dividends shall be payable to
holders of 



<PAGE>   3


record as they appear in the share records of the Corporation at the close of
business on the applicable record date (each, a "Dividend Record Date"), which
shall be the date designated by the Board for the payment of dividends that is
not more than 30 nor less than 10 days prior to the applicable payment date
therefor. Any dividend payable on the Series C Preferred Shares for any partial
dividend period shall be prorated and computed on the basis of a 360-day year
consisting of twelve 30-day months. If any date on which distributions are to be
made on the Series C Preferred Stock is not a business day, then payment of the
distribution to be made on such date will be made on the next succeeding day
that is a business day (and without any interest or other payment in respect of
any such delay) except that, if such business day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding business
day, in each case with the same force and effect as if made on such date.
Notwithstanding any provision to the contrary contained herein, each outstanding
share of Series C Preferred Stock shall be entitled to receive, and shall
receive, a dividend with respect to any Dividend Record Date equal to the
dividend paid with respect to each other share of Series C Preferred Stock which
is outstanding on such date which shall be equal to the greatest dividend per
share payable on any such share on such date. In addition, notwithstanding
anything to the contrary set forth herein, each share of Series C Preferred
Stock shall also continue to accrue all accrued and unpaid distributions up to
the exchange date on any Series C Preferred Unit (as defined in the Third
Amended and Restated Limited Partnership Agreement of AMB Property II, L.P.
dated as of November 24, 1998, as amended and supplemented from time to time
(the "Subsidiary Partnership Agreement")) validly exchanged into such share of
Series C Preferred Stock in accordance with the provisions of the Subsidiary
Partnership Agreement.

        (b) No dividend on the Series C Preferred Shares shall be authorized by
the Board or be paid or set apart for payment by the Corporation at such time as
the terms and provisions of any agreement of the Corporation, including any
agreement relating to its indebtedness, prohibits such authorization, payment or
setting apart for payment or provides that such authorization, payment or
setting apart for payment would constitute a breach thereof, or a default
thereunder, or if such authorization or payment shall be restricted or
prohibited by law.

        (c) Notwithstanding anything to the contrary contained herein, dividends
on the Series C Preferred Shares shall accumulate whether or not restrictions
exist in respect thereof, whether or not there are funds legally available for
the payment thereof and whether or not such dividends are declared or
authorized. Accrued but unpaid dividends on the Series C Preferred Shares will
accumulate as of the Dividend Payment Date on which they first become payable or
on the date of redemption, as the case may be.

        (d) If any Series C Preferred Shares are outstanding, no full dividends
will be declared or paid or set apart for payment on any other equity securities
of the Corporation of any other class or series ranking, as to distributions or
upon voluntary or involuntary liquidation, dissolution or winding up of the
Corporation, junior to or on a parity with the Series C Preferred Shares
(including the Series A Preferred Stock and Series B Preferred Stock) unless
full cumulative dividends have been or contemporaneously are declared and paid
or declared and a sum sufficient for the payment thereof irrevocably set apart
in trust for such payment on the Series C Preferred Shares for all dividend
periods. When dividends are not paid in full (or a sum 



<PAGE>   4


sufficient for such full payment is not so set apart) upon the Series C
Preferred Shares and any other equity securities ranking as to distributions on
a parity with the Series C Preferred Shares (including the Series A Preferred
Stock and Series B Preferred Stock), all dividends declared upon the Series C
Preferred Shares and any other equity securities of the Corporation ranking on a
parity with the Series C Preferred Stock as to distributions and upon voluntary
or involuntary liquidation, dissolution or winding up of the Corporation
(including the Series A Preferred Stock and Series B Preferred Stock) shall be
declared pro rata so that the amount of dividends declared per Series C
Preferred Share and each such other equity securities shall in all cases bear to
each other the same ratio that accumulated dividends per Series C Preferred
Share and such other equity securities (which shall not include any accumulation
in respect of unpaid dividends for prior dividend periods if such other equity
securities do not have a cumulative dividend) bear to each other. No interest,
or sum of money in lieu of interest, shall be payable in respect of any dividend
payment or payments on Series C Preferred Shares which may be in arrears.

        (e) Except as provided in the immediately preceding paragraph, unless
full cumulative dividends on the Series C Preferred Shares have been or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof is irrevocably set apart in trust for payment for all dividend
periods, no dividends (other than in Common Stock or other equity securities of
the Corporation ranking junior to the Series C Preferred Shares as to
distributions and upon voluntary or involuntary liquidation, dissolution and
winding up of the Corporation) shall be declared or paid or set aside for
payment nor shall any other dividend be declared or made upon the Common Stock
or any other equity securities of the Corporation ranking as to distributions or
upon voluntary or involuntary liquidation, dissolution or winding up of the
Corporation junior to or on a parity with the Series C Preferred Stock
(including the Series A Preferred Stock and Series B Preferred Stock), nor shall
any Common Stock or any other equity securities of the Corporation ranking
junior to or on a parity with the Series C Preferred Stock as to distributions
or upon voluntary or involuntary liquidation, dissolution or winding up of the
Corporation (including the Series A Preferred Stock and Series B Preferred
Stock) be redeemed, purchased or otherwise acquired for any consideration (or
any monies be paid to or made available for a sinking fund for the redemption of
any such securities) by the Corporation (except by conversion into or exchange
for other equity securities of the Corporation ranking junior to the Series C
Preferred Stock as to distributions and upon voluntary and involuntary
liquidation, dissolution and winding up of the Corporation, and except pursuant
to Section 7 of this Article Third to ensure the Corporation's continued status
as a REIT or comparable Charter provisions with respect to other classes or
series of the Corporation's stock).

        (f) Accumulated but unpaid dividends on the Series C Preferred Shares
will not bear interest and holders of Series C Preferred Shares shall not be
entitled to any dividend in excess of full cumulative dividends as described
above. Any dividend payment made on the Series C Preferred Shares shall first be
credited against the earliest accumulated but unpaid dividend due with respect
to such shares which remains payable.

        (g) If, for any taxable year, the Corporation elects to designate as a
"capital gain dividend" (as defined in Section 857 of the Code), any portion
(the "Capital Gains Amount") of the dividends paid or made available for the
year to holders of every class or series of stock of 



<PAGE>   5


the Corporation, the portion of the Capital Gains Amount that shall be allocable
to holders of the Series C Preferred Stock shall be the amount that the total
dividends (as determined for Federal income tax purposes) paid or made available
to the holders of the Series C Preferred Stock for the year bears to the
aggregate amount of dividends (as determined for Federal income tax purposes)
paid or made available to the holders of all classes or series of stock of the
Corporation for such year.

        (4)  LIQUIDATION PREFERENCE.

        (a)     In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, the holders of Series C Preferred
Shares then outstanding shall be entitled to receive out of the assets of the
Corporation legally available for distribution to its stockholders remaining
after payment or provision for payment of all debts and liabilities of the
Corporation, a liquidation preference in cash of $50.00 per share, plus an
amount equal to any accumulated or accrued and unpaid dividends to the date of
such payment, before any distribution of assets is made to holders of Common
Stock or any other equity securities of the Corporation that rank junior to the
Series C Preferred Shares as to liquidation rights.

        (b)     If, upon any such voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, the assets of the Corporation are
insufficient to make full payment to holders of Series C Preferred Shares and
the corresponding amounts payable on all shares of other classes or series of
equity securities of the Corporation ranking on a parity with the Series C
Preferred Shares as to liquidation rights (including the Series A Preferred
Stock and Series B Preferred Stock), then the holders of the Series C Preferred
Shares and all other such classes or series of equity securities shall share
ratably in any such distribution of assets in proportion to the full liquidating
distributions to which they would otherwise be respectively entitled.

        (c)     Written notice of any such liquidation, dissolution or winding
up of the Corporation, stating the payment date or dates when, and the place or
places where, the amounts distributable in such circumstances shall be payable,
shall be given by first class mail, postage pre-paid, not less than 30 nor more
than 60 days prior to the payment date stated therein, to each record holder of
the Series C Preferred Shares at the respective addresses of such holders as the
same shall appear on the stock transfer records of the Corporation.

        (d)     After payment of the full amount of the liquidating
distributions to which they are entitled, the holders of Series C Preferred
Shares will have no right or claim to any of the remaining assets of the
Corporation.

        (e)     The consolidation or merger of the Corporation with or into any
other entity, a merger of another entity with or into the Corporation, a
statutory share exchange by the Corporation or a sale, lease, transfer or
conveyance of all or substantially all of the property or business of the
Corporation shall not be deemed to constitute a liquidation, dissolution or
winding up of the Corporation.

        (f)     In determining whether a distribution (other than upon voluntary
or involuntary liquidation, dissolution or winding up of the Corporation) by
dividend, redemption or other 



<PAGE>   6


acquisition of shares of stock of the Corporation or otherwise is permitted
under the MGCL, no effect shall be given to amounts that would be needed, if the
Corporation were to be dissolved at the time of the distribution, to satisfy the
preferential rights upon dissolution of holders of the Series C Preferred Shares
whose preferential rights upon dissolution are superior to those receiving the
distribution.

        (5)  OPTIONAL REDEMPTION.

        (a)     The Series C Preferred Shares are not redeemable prior to
November 24, 2003. To ensure that the Corporation remains a qualified real
estate investment trust ("REIT") for federal income tax purposes, however, the
Series C Preferred Shares shall be subject to the provisions of Section 7 of
this Article Third pursuant to which Series C Preferred Shares owned by a
stockholder in excess of the Ownership Limit (as defined in Section 7 of this
Article Third) or certain other limitations shall automatically be transferred
to a Trust for the benefit of a Charitable Beneficiary (as defined in Section 7
of this Article Third) and the Corporation shall have the right to purchase such
shares, as provided in Section 7 of this Article Third. On and after November
24, 2003, the Corporation, at its option, upon giving notice as provided below,
may redeem the Series C Preferred Shares, in whole or from time to time in part,
for cash, at a redemption price of $50.00 per share, plus all accumulated and
unpaid dividends on such Series C Preferred Shares to the date fixed for
redemption.

        (b)     The redemption price of the Series C Preferred Shares (other
than any portion thereof consisting of accumulated and unpaid dividends) is
payable solely from the sale proceeds of other equity securities of the
Corporation, and not from any other source. For purposes of the preceding
sentence, "equity securities" means any equity securities (including Common
Stock and Preferred Stock (as defined in the Charter)), depositary shares in
respect of any of the foregoing, interests, participations or other ownership
interests (however designated) and any rights (other than debt securities
convertible into or exchangeable for equity securities) or options to purchase
any of the foregoing.

        (c)     If fewer than all of the outstanding Series C Preferred Shares
are to be redeemed, the shares to be redeemed shall be selected pro rata (as
nearly as practicable without creating fractional shares).

        (d)     Notwithstanding anything to the contrary contained herein,
unless full cumulative dividends on all Series C Preferred Shares shall have
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment thereof set apart for payment for all past dividend periods and
the then current dividend period, no Series C Preferred Shares shall be redeemed
unless all outstanding Series C Preferred Shares are simultaneously redeemed;
provided, however, that the foregoing shall not prevent the purchase by the
Corporation of Series C Preferred Shares pursuant to Section 7 of this Article
Third or otherwise in order to ensure that the Corporation remains qualified as
a REIT for Federal or state income tax purposes or the purchase or acquisition
of Series C Preferred Shares pursuant to a purchase or exchange offer made on
the same terms to holders of all outstanding Series C Preferred Shares. In
addition, unless full cumulative dividends on all outstanding Series C Preferred
Shares have been or contemporaneously are declared and paid or declared and a
sum sufficient for the payment 



<PAGE>   7


thereof irrevocably set apart in trust for payment for all dividend periods, the
Corporation shall not purchase or otherwise acquire directly or indirectly any
Series C Preferred Shares or any equity securities of the Corporation ranking
junior to or on a parity with the Series C Preferred Shares as to dividends or
upon voluntary or involuntary liquidation, dissolution or winding up of the
Corporation (including the Series A Preferred Stock and Series B Preferred
Stock) (except by conversion into or exchange for equity securities of the
Corporation ranking junior to the Series C Preferred Shares as to dividends and
upon voluntary or involuntary liquidation, dissolution or winding up of the
Corporation and except pursuant to Section 7 of this Article Third or comparable
Charter provisions with respect to other classes or series of the Corporation's
stock).

        (e)     The holders of shares of Series C Preferred Stock at the close
of business on a Dividend Record Date will be entitled to receive the dividend
payable with respect to the shares of Series C Preferred Stock held on the
corresponding Dividend Payment Date notwithstanding the redemption thereof
between such Dividend Record Date and the corresponding Dividend Payment Date or
the Corporation's default in the payment of the dividend due. Except as provided
herein, the Corporation will make no payment or allowance for unpaid dividends,
whether or not in arrears, on Series C Preferred Shares to be redeemed.

        (f)     The following provisions set forth the procedures for
Redemption:

                (i) Notice of redemption will be given by publication in a
newspaper of general circulation in the City of New York, such publication to be
made once a week for two successive weeks commencing not less than 30 nor more
than 60 days prior to the redemption date. A similar notice will be (i) faxed
and (ii) mailed by the Corporation, postage prepaid, not less than 30 nor more
than 60 days prior to the redemption date, addressed to the respective holders
of record of the Series C Preferred Shares to be redeemed at their respective
addresses as they appear on the share records of the Corporation. No failure to
give such notice or any defect therein or in the mailing thereof shall affect
the validity of the proceedings for the redemption of any Series C Preferred
Shares except as to the holder to whom notice was defective or not given.

                (ii) In addition to any information required by law or by the
applicable rules of any exchange upon which the Series C Preferred Shares may be
listed or admitted to trading, such notice shall state: (A) the redemption date;
(B) the redemption price; (C) the number of Series C Preferred Shares to be
redeemed; (D) the place or places where the certificates evidencing shares of
Series C Preferred Shares are to be surrendered for payment of the redemption
price; and (E) that dividends on the Series C Preferred Shares to be redeemed
will cease to accumulate on such redemption date. If fewer than all of the
Series C Preferred Shares held by any holder are to be redeemed, the notice
mailed to such holder shall also specify the number of Series C Preferred Shares
to be redeemed from such holder.

                (iii) On or after the redemption date, each holder of Series C
Preferred Shares to be redeemed shall present and surrender the certificates
representing such holder's Series C Preferred Shares to the Corporation at the
place designated in the notice of redemption and shall be entitled to the
redemption price and any accrued or accumulated and unpaid dividends payable
upon such redemption upon such surrender and thereupon the redemption price of
such shares (including all accumulated and unpaid dividends up to the redemption
date) shall be paid to or on 




<PAGE>   8


the order of the person whose name appears on such certificate representing
Series C Preferred Shares as the owner thereof and each surrendered certificate
shall be canceled. If fewer than all the shares represented by any such
certificate representing Series C Preferred Shares are to be redeemed, a new
certificate shall be issued representing the unredeemed shares.

                (iv) If notice of redemption of any Series C Preferred Shares
has been given and if the funds necessary for such redemption have been
irrevocably set aside by the Corporation in trust for the benefit of the holders
thereof, then from and after the redemption date all dividends on such Series C
Preferred Shares shall cease to accumulate and any such Series C Preferred
Shares will no longer be deemed outstanding and all rights of the holders
thereof will terminate, except the right to receive the redemption price
(including all accrued or accumulated and unpaid dividends up to the redemption
date) and such shares shall not thereafter be transferred (except with the
consent of the Corporation) on the Corporation's stock transfer records. At its
election, the Corporation, prior to a redemption date, may irrevocably deposit
the redemption price (including accumulated and unpaid dividends to the
redemption date) of the Series C Preferred Shares so called for redemption in
trust for the holders thereof with a bank or trust company, in which case the
redemption notice to holders of the Series C Preferred Shares to be redeemed
shall (A) state the date of such deposit, (B) specify the office of such bank or
trust company as the place of payment of the redemption price and (C) require
such holders to surrender the certificates representing such shares at such
place on or about the date fixed in such redemption notice (which may not be
later than the redemption date) against payment of the redemption price
(including all accrued or accumulated and unpaid dividends to the redemption
date). Any monies so deposited which remain unclaimed by the holders of the
Series C Preferred Shares at the end of two years after the redemption date
shall be returned by such bank or trust company to the Corporation.

        (g)     Any Series C Preferred Shares that shall at any time have been
redeemed shall, after such redemption, have the status of authorized but
unissued Preferred Stock, without further designation as to series or class
until such shares are once more designated as part of a particular series or
class by the Board.

        (6) VOTING RIGHTS.

        (a)     Holders of the Series C Preferred Shares will not have any
voting rights, except as set forth below.

        (b)     (i) Whenever dividends on any Series C Preferred Shares shall
remain unpaid for six or more quarterly periods (whether or not consecutive) (a
"Preferred Dividend Default"), the holders of such Series C Preferred Shares
(voting as a single class with all other equity securities of the Corporation
ranking on a parity with the Series C Preferred Shares as to dividends and upon
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation upon which like voting rights have been conferred and are
exercisable, including the Series A Preferred Stock and Series B Preferred Stock
("Parity Preferred Stock")) will be entitled to vote for the election of two
additional directors of the Corporation (the "Preferred Stock Directors"), who
will be elected by a plurality of the votes cast in such election for a one-year
term and until their successors are duly elected and shall qualify (or until
such director's right to hold such 



<PAGE>   9


office terminates as provided herein, whichever occurs earlier, subject to such
director's earlier death, disqualification, resignation or removal), at a
special meeting called by the holders of at least 20% of the outstanding Series
C Preferred Shares or the holders of shares of any other class or series of
Parity Preferred Stock with respect to which dividends are so unpaid (unless
such request is received less than 90 days before the date fixed for the next
annual or special meeting of stockholders) or, if the request for a special
meeting is received by the Corporation less than 90 days before the date fixed
for the next annual or special meeting of stockholders, at the next annual or
special meeting of stockholders, and at each subsequent annual meeting until all
dividends accumulated on the Series C Preferred Shares for all past dividend
periods and the dividend for the then current dividend period shall have been
fully paid or declared and a sum sufficient for the payment thereof irrevocably
set aside in trust for payment in full.

                (ii) At any time when the voting rights described in Section
6(b)(i) above shall have vested, a proper officer of the Corporation shall call
or cause to be called, a special meeting of the holders of Series C Preferred
Stock and all the series of Parity Preferred Stock upon which like voting rights
have been conferred and are exercisable (collectively, the "Parity Securities")
by mailing or causing to be mailed to such holders a notice of such special
meeting to be held not less than ten and not more than 45 days after the date
such notice is given. The record date for determining holders of the Parity
Securities entitled to notice of and to vote at such special meeting will be the
close of business on the third business day preceding the day on which such
notice is mailed. At any such special meeting, all of the holders of the Parity
Securities, by plurality vote, voting together as a single class without regard
to series will be entitled to elect two directors on the basis of one vote per
$25.00 of liquidation preference to which such Parity Securities are entitled by
their terms (excluding amounts in respect of accumulated and unpaid dividends)
and not cumulatively. Notice of all meetings at which holders of the Series C
Preferred Shares shall be entitled to vote will be given to such holders at
their addresses as they appear in the transfer records. If a Preferred Dividend
Default shall terminate after the notice of a special meeting has been given but
before such special meeting has been held, the Corporation shall, as soon as
practicable after such termination, mail or cause to be mailed notice of such
termination to holders of the Series C Preferred Shares that would have been
entitled to vote at such special meeting.

        (c)     If and when all accumulated dividends and the dividend for the
then current dividend period on the Series C Preferred Shares shall have been
paid in full or declared by the Corporation and irrevocably set aside in trust
for payment in full, the holders of Series C Preferred Shares shall be divested
of the voting rights set forth in Section 6(b) of this Article Third (subject to
revesting in the event of each and every Preferred Dividend Default) and, if all
accumulated dividends have been paid in full or declared by the Corporation and
irrevocably set aside in trust for payment in full on all other classes or
series of Parity Preferred Stock upon which like voting rights have been
conferred and are exercisable, the term of office of each Preferred Stock
Director so elected shall forthwith terminate. Any Preferred Stock Director
elected by the holders of Series C Preferred Shares and any other such Parity
Preferred Shares may be removed at any time with or without cause by the vote
of, and shall not be removed otherwise than by the vote of, the holders of a
majority of the outstanding Series C Preferred Shares when they have the voting
rights set forth, or like those set forth, in Section 6(b) of this 



<PAGE>   10


Article Third, by the majority vote of the Series C Preferred Shares and all
other classes or series of Parity Preferred Stock upon which like voting rights
have been conferred and are exercisable (voting as a single class) when the
Series C Preferred Shares and such Parity Preferred Stock is entitled to vote
thereon. So long as a Preferred Dividend Default shall continue, any vacancy in
the office of a Preferred Stock Director so elected may be filled by written
consent of the Preferred Stock Director so elected remaining in office or, if
none remains in office, by a vote of the holders of a majority of the
outstanding Series C Preferred Shares when they only have the voting rights set
forth, or like those set forth, in Section 6(b) of this Article Third and by the
majority vote of the Series C Preferred Shares and other classes or series of
Parity Preferred Stock upon which like voting rights have been conferred and are
exercisable (voting as a single class) when the Series C Preferred Shares and
such Parity Preferred Stock is entitled to vote thereon.

        (d)     So long as any Series C Preferred Stock remains outstanding, the
Corporation shall not, without the affirmative vote of the holders of at least
two-thirds of the Series C Preferred Stock outstanding at the time (i) authorize
or create, or increase the authorized or issued amount of, any class or series
of shares ranking senior to the Series C Preferred Stock with respect to payment
of distributions or rights upon liquidation, dissolution or winding-up or
reclassify any authorized shares of the Corporation into any such shares, or
create, authorize or issue any obligations or security convertible into or
evidencing the right to purchase any such shares, (ii) designate or create, or
increase the authorized or issued amount of, any Parity Preferred Stock or
reclassify any authorized shares of the Corporation into any such shares, or
create, authorize or issue any obligations or security convertible into or
evidencing the right to purchase any such shares, but only to the extent such
Parity Preferred Stock is issued to an affiliate of the Corporation, or (iii)
either (A) consolidate, merge into or with, or convey, transfer or lease its
assets substantially as an entirety, to any corporation or other entity, or (B)
amend, alter or repeal the provisions of the Corporation's Charter (including
these Articles Supplementary) or Bylaws, whether by merger, consolidation or
otherwise, in each case that would materially and adversely affect the powers,
special rights, preferences, privileges or voting power of the Series C
Preferred Stock or the holders thereof; provided, however, that with respect to
the occurrence of any event set forth in (A) above, so long as (a) the
Corporation is the surviving entity and the Series C Preferred stock remains
outstanding with the terms thereof unchanged, or (b) the resulting, surviving or
transferee entity is a corporation, a business trust or like entity organized
under the laws of any state and substitutes for the Series C Preferred Stock
other preferred stock or preferred shares having substantially the same terms
and same rights as the Series C Preferred Stock, including with respect to
distributions, voting rights and rights upon liquidation, dissolution or
winding-up, then the occurrence of any such event shall not be deemed to
materially and adversely affect such rights, privileges or voting powers of the
holders of the Series C Preferred Stock and provided further that any increase
in the amount of authorized Preferred Stock or the creation or issuance of any
other class or series of Preferred Stock, or any increase in an amount of
authorized shares of each class or series, in each case ranking either (a)
junior to the Series C Preferred Stock with respect to payment of distributions
and the distribution of assets upon liquidation, dissolution or winding-up, or
(b) on a parity with the Series C Preferred Stock with respect to payment of
distributions and the distribution of assets upon liquidation, dissolution or
winding-up to the extent such Preferred Stock is not issued 






<PAGE>   11


to an affiliate of the Corporation, shall not be deemed to materially and
adversely affect such rights, preferences, privileges or voting powers.

        (e)     The foregoing voting provisions shall not apply if, at or prior
to the time when the act with respect to which such vote would otherwise be
required shall be effected, all outstanding Series C Preferred Shares shall have
been redeemed or called for redemption upon proper notice and sufficient funds
shall have been irrevocably deposited in trust to effect such redemption.

                unless the Purported Record Transferee would have acquired or
                owned shares of Series C Preferred Stock for another Person who
                is the beneficial transferee or owner of such shares, in which
                case the Purported Beneficial Transferee shall be such Person.

                        "Purported Record Transferee" shall mean, with respect
                to any purported Transfer (or other event) which results in a
                transfer to a Trust, as provided in Section 7(b)(ii) of these
                Articles Supplementary, the record holder of the Series C
                Preferred Stock if such Transfer had been valid under Section
                7(b)(i) of these Articles Supplementary.

                comparable provisions of the law of such state.

                        "Restriction Termination Date" shall mean the first day
                after the date hereof on which the Board of Directors of the

                into any agreement for the sale, transfer or other disposition
                of Series C Preferred Stock or (ii) the sale, transfer,
                assignment or other disposition of any securities (or rights
                convertible into or exchangeable for Series C Preferred Stock),
                whether voluntary or involuntary, whether such transfer has
                occurred of record or beneficially or Beneficially or
                Constructively (including but not limited to transfers of
                interests in other entities which result in changes in
                Beneficial or Constructive Ownership of Series C Preferred
                Stock), and whether such transfer has occurred by operation of
                law or otherwise.

                        "Trust" shall mean each of the trusts provided for in

        (b)     Restriction on Ownership and Transfers.

                (i) Prior to the Restriction Termination Date:

                        (A) except as provided in Section 7(i) of these Articles
Supplementary, no Person shall Beneficially Own Series C Preferred Stock which,
taking into account any other capital stock of the Corporation Beneficially
Owned by such Person, would cause such ownership to exceed the Ownership Limit;

                        (B) except as provided in Section 7(i) of these Articles
Supplementary, no Person shall Constructively Own Series C Preferred Stock
which, taking into account any other capital stock of the Corporation
Constructively Owned by such Person, would cause such ownership to exceed the
Ownership Limit;

                        (C) no Person shall Beneficially or Constructively Own
Series C Preferred Stock which, taking into account any other capital stock of
the Corporation Beneficially or Constructively Owned by such Person, would
result in the Corporation being "closely held" within the meaning of Section
856(h) of the Code, or otherwise failing to qualify as a REIT (including but not
limited to Beneficial or Constructive Ownership that would result in the
Corporation owning (actually or Constructively) an interest in a tenant that is
described in 




<PAGE>   14


Section 856(d)(2)(B) of the Code if the income derived by the Corporation
(either directly or indirectly through one or more partnerships or limited
liability companies) from such tenant would cause the Corporation to fail to
satisfy any of the gross income requirements of Section 856(c) of the Code or
comparable provisions of state law).

                (ii) If, prior to the Restriction Termination Date, any Transfer
or other event occurs that, if effective, would result in any Person
Beneficially or Constructively Owning Series C Preferred Stock in violation of
Section 7(b)(i) of these Articles Supplementary, (1) then that number of shares
of Series C Preferred Stock that otherwise would cause such Person to violate
Section 7(b)(i) of these Articles Supplementary (rounded up to the nearest whole
share) shall be automatically transferred to a Trust for the benefit of a
Charitable Beneficiary, as described in Section 7(c), effective as of the close
of business on the business day prior to the date of such Transfer or other
event, and such Purported Beneficial Transferee shall thereafter have no rights
in such shares or (2) if, for any reason, the transfer to the Trust described in
clause (1) of this sentence is not automatically effective as provided therein
to prevent any Person from Beneficially or Constructively Owning Series C
Preferred Stock in violation of Section 7(b)(i) of these Articles Supplementary,
then the Transfer of that number of shares of Series C Preferred Stock that
otherwise would cause any Person to violate Section 7(b)(i) shall be void ab
initio, and the Purported Beneficial Transferee shall have no rights in such
shares. 

                (iii) Subject to Section 7(n) of this Article Third and
notwithstanding any other provisions contained herein, prior to the Restriction
Termination Date, any Transfer of Series C Preferred Stock that, if effective,
would result in the capital stock of the Corporation being beneficially owned by
less than 100 Persons (determined without reference to any rules of attribution)
shall be void ab initio, and the intended transferee shall acquire no rights in
such Series C Preferred Stock.

                It is expressly intended that the restrictions on ownership and
Transfer described in this Section 7(b) shall apply to the exchange rights
provided in Section 16.8 of the Subsidiary Partnership Agreement.
Notwithstanding any of the provisions of the Subsidiary Partnership Agreement to
the contrary, a partner of the Subsidiary Operating Partnership shall not be
entitled to effect an exchange of an interest in the Subsidiary Operating
Partnership for Series C Preferred Stock if the actual or beneficial or
Beneficial or Constructive Ownership of Series C Preferred Stock would be
prohibited under the provisions of this Section 7.

        (c)     Transfers of Series C Preferred Stock in Trust.

                (i) Upon any purported Transfer or other event described in
Section 7(b)(ii) of these Articles Supplementary, such Series C Preferred Stock
shall be deemed to have been transferred to the Trustee in his capacity as
trustee of a Trust for the exclusive benefit of one or more Charitable
Beneficiaries. Such transfer to the Trustee shall be deemed to be effective as
of the close of business on the business day prior to the purported Transfer or
other event that results in a transfer to the Trust pursuant to Section
7(b)(ii). The Trustee shall be appointed by the Corporation and shall be a
Person unaffiliated with the Corporation, any Purported Beneficial Transferee,
or any Purported Record Transferee. Each Charitable Beneficiary shall be
designated by the Corporation as provided in Section 7(c)(vi) of these Articles
Supplementary.



<PAGE>   15


                (ii) Series C Preferred Stock held by the Trustee shall be
issued and outstanding Series C Preferred Stock of the Corporation. The
Purported Beneficial Transferee or Purported Record Transferee shall have no
rights in the shares of Series C Preferred Stock held by the Trustee. The
Purported Beneficial Transferee or Purported Record Transferee shall not benefit
economically from ownership of any shares held in trust by the Trustee, shall
have no rights to dividends and shall not possess any rights to vote or other
rights attributable to the shares of Series C Preferred Stock held in the Trust.

                (iii) The Trustee shall have all voting rights and rights to
dividends with respect to Series C Preferred Stock held in the Trust, which
rights shall be exercised for the exclusive benefit of the Charitable
Beneficiary. Any dividend or distribution paid prior to the discovery by the
Corporation that shares of Series C Preferred Stock have been transferred to the
Trustee shall be paid to the Trustee upon demand, and any dividend or
distribution declared but unpaid shall be paid when due to the Trustee with
respect to such Series C Preferred Stock. Any dividends or distributions so paid
over to the Trustee shall be held in trust for the Charitable Beneficiary.

                The Purported Record Transferee and Purported Beneficial
Transferee shall have no voting rights with respect to the Series C Preferred
Stock held in the Trust and, subject to Maryland law, effective as of the date
the Series C Preferred Stock has been transferred to the Trustee, the Trustee
shall have the authority (at the Trustee's sole discretion) (i) to rescind as
void any vote cast by a Purported Record Transferee with respect to such Series
C Preferred Stock prior to the discovery by the Corporation that the Series C
Preferred Stock has been transferred to the Trustee and (ii) to recast such vote
in accordance with the desires of the Trustee acting for the benefit of the
Charitable Beneficiary; provided, however, that if the Corporation has already
taken irreversible corporate action, then the Trustee shall not have the
authority to rescind and recast such vote. Notwithstanding any other provision
of these Articles Supplementary to the contrary, until the Corporation has
received notification that the Series C Preferred Stock has been transferred
into a Trust, the Corporation shall be entitled to rely on its share transfer
and other stockholder records for purposes of preparing lists of stockholders
entitled to vote at meetings, determining the validity and authority of proxies
and otherwise conducting votes of stockholders.

                (iv) Within 20 days of receiving notice from the Corporation
that shares of Series C Preferred Stock have been transferred to the Trust, the
Trustee of the Trust shall sell the shares of Series C Preferred Stock held in
the Trust to a Person, designated by the Trustee, whose ownership of the shares
of Series C Preferred Stock will not violate the ownership limitations set forth
in Section 7(b)(i). Upon such sale, the interest of the Charitable Beneficiary
in the shares of Series C Preferred Stock sold shall terminate and the Trustee
shall distribute the net proceeds of the sale to the Purported Record Transferee
and to the Charitable Beneficiary as provided in this Section 7(c)(iv). The
Purported Record Transferee shall receive the lesser of (1) the price paid by
the Purported Record Transferee for the shares of Series C Preferred Stock in
the transaction that resulted in such transfer to the Trust (or, if the event
which resulted in the transfer to the Trust did not involve a purchase of such
shares of Series C Preferred Stock at Market Price, the Market Price of such
shares of Series C Preferred Stock on the day of the event 





<PAGE>   16


which resulted in the transfer of such shares of Series C Preferred Stock to the
Trust) and (2) the price per share received by the Trustee (net of any
commissions and other expenses of sale) from the sale or other disposition of
the shares of Series C Preferred Stock held in the Trust. Any net sales proceeds
in excess of the amount payable to the Purported Record Transferee shall be
immediately paid to the Charitable Beneficiary together with any dividends or
other distributions thereon. If, prior to the discovery by the Corporation that
shares of such Series C Preferred Stock have been transferred to the Trustee,
such shares of Series C Preferred Stock are sold by a Purported Record
Transferee then (i) such shares of Series C Preferred Stock shall be deemed to
have been sold on behalf of the Trust and (ii) to the extent that the Purported
Record Transferee received an amount for such shares of Series C Preferred Stock
that exceeds the amount that such Purported Record Transferee was entitled to
receive pursuant to this Section 7(c)(iv), such excess shall be paid to the
Trustee upon demand.

                (v) Series C Preferred Stock transferred to the Trustee shall be
deemed to have been offered for sale to the Corporation, or its designee, at a
price per share equal to the lesser of (i) the price paid by the Purported
Record Transferee for the shares of Series C Preferred Stock in the transaction
that resulted in such transfer to the Trust (or, if the event which resulted in
the transfer to the Trust did not involve a purchase of such shares of Series C
Preferred Stock at Market Price, the Market Price of such shares of Series C
Preferred Stock on the day of the event which resulted in the transfer of such
shares of Series C Preferred Stock to the Trust) and (ii) the Market Price on
the date the Corporation, or its designee, accepts such offer. The Corporation
shall have the right to accept such offer until the Trustee has sold the shares
of Series C Preferred Stock held in the Trust pursuant to Section 7(c)(iv). Upon
such a sale to the Corporation, the interest of the Charitable Beneficiary in
the shares of Series C Preferred Stock sold shall terminate and the Trustee
shall distribute the net proceeds of the sale to the Purported Record Transferee
and any dividends or other distributions held by the Trustee with respect to
such Series C Preferred Stock shall thereupon be paid to the Charitable
Beneficiary.

                (vi) By written notice to the Trustee, the Corporation shall
designate one or more nonprofit organizations to be the Charitable Beneficiary
of the interest in the Trust such that the Series C Preferred Stock held in the
Trust would not violate the restrictions set forth in Section 7(b)(i) in the
hands of such Charitable Beneficiary.

        (d)     Remedies For Breach. If the Board of Directors or a committee
thereof or other designees if permitted by the MGCL shall at any time determine
in good faith that a Transfer or other event has taken place in violation of
Section 7(b) of these Articles Supplementary or that a Person intends to
acquire, has attempted to acquire or may acquire beneficial ownership
(determined without reference to any rules of attribution), Beneficial Ownership
or Constructive Ownership of any shares of Series C Preferred Stock of the
Corporation in violation of Section 7(b) of these Articles Supplementary, the
Board of Directors or a committee thereof or other designees if permitted by the
MGCL shall take such action as it deems advisable to refuse to give effect or to
prevent such Transfer, including, but not limited to, causing the Corporation to
redeem shares of Series C Preferred Stock, refusing to give effect to such
Transfer on the books of the Corporation or instituting proceedings to enjoin
such Transfer; provided, however, that any Transfers (or, in the case of events
other than a Transfer, ownership or Constructive Ownership 




<PAGE>   17


or Beneficial Ownership) in violation of Section 7(b)(i) of these Articles
Supplementary, shall automatically result in the transfer to a Trust as
described in Section 7(b)(ii) and any Transfer in violation of Section 7(b)(iii)
shall automatically be void ab initio irrespective of any action (or non-action)
by the Board of Directors.

        (e)     Notice of Restricted Transfer. Any Person who acquires or
attempts to acquire shares of Series C Preferred Stock in violation of Section
7(b) of these Articles Supplementary, or any Person who is a Purported
Beneficial Transferee such that an automatic transfer to a Trust results under
Section 7(b)(ii) of these Articles Supplementary, shall immediately give written
notice to the Corporation of such event and shall provide to the Corporation
such other information as the Corporation may request in order to determine the
effect, if any, of such Transfer or attempted Transfer on the Corporation's
status as a REIT.

        (f)     Owners Required To Provide Information. Prior to the Restriction
Termination Date each Person who is a beneficial owner or Beneficial Owner or
Constructive Owner of Series C Preferred Stock and each Person (including the
shareholder of record) who is holding Series C Preferred Stock for a beneficial
owner or Beneficial Owner or Constructive Owner shall provide to the Corporation
such information that the Corporation may request, in good faith, in order to
determine the Corporation's status as a REIT.

        (g)     Remedies Not Limited. Nothing contained in these Articles
Supplementary (but subject to Section 7(n) of these Articles Supplementary)
shall limit the authority of the Board of Directors to take such other action as
it deems necessary or advisable to protect the Corporation and the interests of
its shareholders by preservation of the Corporation's status as a REIT.

        (h)     Ambiguity. In the case of an ambiguity in the application of any
of the provisions of this Section 7 of these Articles Supplementary, including
any definition contained in Section 7(a), the Board of Directors shall have the
power to determine the application of the provisions of this Section 7 with
respect to any situation based on the facts known to it (subject, however, to
the provisions of Section 7(n) of these Articles Supplementary). In the event
Section 7 requires an action by the Board of Directors and these Articles
Supplementary fail to provide specific guidance with respect to such action, the
Board of Directors shall have the power to determine the action to be taken so
long as such action is not contrary to the provisions of Section 7. Absent a
decision to the contrary by the Board of Directors (which the Board may make in
its sole and absolute discretion), if a Person would have (but for the remedies
set forth in Section 7(b)) acquired Beneficial or Constructive Ownership of
Series C Preferred Stock in violation of Section 7(b)(i), such remedies (as
applicable) shall apply first to the shares of Series C Preferred Stock which,
but for such remedies, would have been actually owned by such Person, and second
to shares of Series C Preferred Stock which, but for such remedies, would have
been Beneficially Owned or Constructively Owned (but not actually owned) by such
Person, pro rata among the Persons who actually own such shares of Series C
Preferred Stock based upon the relative number of the shares of Series C
Preferred Stock held by each such Person.

        (i)     Exceptions.



<PAGE>   18


                (i) Subject to Section 7(b)(i)(C), the Board of Directors, in
its sole discretion, may exempt a Person from the limitation on a Person
Beneficially Owning shares of Series C Preferred Stock in violation of Section
7(b)(i)(A) if the Board of Directors obtains any representations and
undertakings from such Person as are reasonably necessary in the opinion of the
Board of Directors to ascertain that no individual's Beneficial Ownership of
such shares of Series C Preferred Stock will violate Section 7(b)(i)(A) or that
any such violation will not cause the Corporation to fail to qualify as a REIT
under the Code, and that any violation of such representations or undertakings
(or other action which is contrary to the restrictions contained in Section 7(b)
of these Articles Supplementary) or attempted violation will result in such
Series C Preferred Stock being transferred to a Trust in accordance with Section
7(b)(ii) of these Articles Supplementary.

                (ii) Subject to Section 7(b)(i)(C), the Board of Directors, in
its sole discretion, may exempt a Person from the limitation on a Person
Constructively Owning Series C Preferred Stock in violation of Section
7(b)(i)(B), if the Corporation obtains such representations and undertakings
from such Person as are reasonably necessary in the opinion of the Board of
Directors to ascertain that such Person does not and will not own, actually or
Constructively, an interest in a tenant of the Corporation (or a tenant of any
entity owned in whole or in part by the Corporation) that would cause the
Corporation to own, actually or Constructively, more than a 9.8% interest (as
set forth in Section 856(d)(2)(B) of the Code) in such tenant and that any
violation or attempted violation will result in such Series C Preferred Stock
being transferred to a Trust in accordance with Section 7(b)(ii) of these
Articles Supplementary. Notwithstanding the foregoing, the inability of a Person
to make the certification described in this Section 7(i)(ii) shall not prevent
the Board of Directors, in its sole discretion, from exempting such Person from
the limitation on a Person Constructively Owning Series C Preferred Stock in
violation of Section 7(b)(i)(B) if the Board of Directors determines that the
resulting application of Section 856(d)(2)(B) of the Code would affect the
characterization of less than 0.5% of the gross income (as such term is used in
Section 856(c)(2) of the Code) of the Corporation in any taxable year, after
taking into account the effect of this sentence with respect to all other
capital stock of the Corporation to which this sentence applies.

                (iii) Prior to granting any exception pursuant to Section
7(i)(i) or (ii) of these Articles Supplementary, the Board of Directors may
require a ruling from the Internal Revenue Service, or an opinion of counsel, in
either case in form and substance satisfactory to the Board of Directors in its
sole discretion, as it may deem necessary or advisable in order to determine or
ensure the Corporation's status as a REIT.

        (j)     Legends. Each certificate for Series C Preferred Stock shall

        SERIES C PREFERRED STOCK, (i) NO PERSON MAY BENEFICIALLY OWN SHARES OF
        THE CORPORATION'S SERIES C PREFERRED STOCK WHICH, TAKING INTO ACCOUNT
        ANY OTHER CAPITAL STOCK OF THE CORPORATION BENEFICIALLY OWNED BY SUCH
        PERSON, WOULD CAUSE SUCH OWNERSHIP TO EXCEED THE OWNERSHIP LIMIT OF
        9.8%; (ii) NO PERSON MAY CONSTRUCTIVELY OWN SHARES OF THE CORPORATION'S
        SERIES C PREFERRED STOCK WHICH, TAKING INTO ACCOUNT ANY OTHER CAPITAL

        PREFERRED STOCK THAT, TAKING INTO ACCOUNT ANY OTHER CAPITAL STOCK OF THE
        CORPORATION BENEFICIALLY OR CONSTRUCTIVELY OWNED BY SUCH PERSON, WOULD
        RESULT IN THE CORPORATION BEING "CLOSELY HELD" UNDER SECTION 856(h) OF
        THE CODE OR OTHERWISE CAUSE THE CORPORATION TO FAIL TO QUALIFY AS A
        REIT; AND (iv) NO PERSON MAY TRANSFER SHARES OF SERIES C PREFERRED STOCK
        IF SUCH TRANSFER WOULD RESULT IN THE CAPITAL STOCK OF THE CORPORATION
        BEING OWNED BY FEWER THAN 100 PERSONS. ANY PERSON WHO BENEFICIALLY OR
        CONSTRUCTIVELY OWNS OR ATTEMPTS TO BENEFICIALLY OR CONSTRUCTIVELY OWN
        SERIES C PREFERRED STOCK WHICH CAUSES OR WILL CAUSE A PERSON TO
        BENEFICIALLY OR CONSTRUCTIVELY OWN SERIES C PREFERRED STOCK IN EXCESS OF
        THE ABOVE LIMITATIONS MUST IMMEDIATELY NOTIFY THE CORPORATION. IF ANY OF
        THE RESTRICTIONS ON TRANSFER OR OWNERSHIP ARE VIOLATED, THE SERIES C
        PREFERRED STOCK REPRESENTED HEREBY WILL BE AUTOMATICALLY TRANSFERRED TO
        THE TRUSTEE OF A TRUST FOR THE BENEFIT OF ONE OR MORE CHARITABLE
        BENEFICIARIES. IN ADDITION, THE CORPORATION MAY REDEEM SHARES UPON THE
        TERMS AND CONDITIONS SPECIFIED BY THE BOARD OF DIRECTORS IN ITS SOLE
        DISCRETION IF THE BOARD OF DIRECTORS DETERMINES THAT OWNERSHIP OR A
        TRANSFER OR OTHER EVENT MAY VIOLATE THE RESTRICTIONS DESCRIBED ABOVE.
        FURTHERMORE, UPON THE OCCURRENCE OF CERTAIN EVENTS, ATTEMPTED TRANSFERS
        IN VIOLATION OF THE RESTRICTIONS DESCRIBED ABOVE MAY BE VOID AB INITIO.
        ALL TERMS IN THIS LEGEND WHICH ARE DEFINED IN THE ARTICLES SUPPLEMENTARY
        FOR THE SERIES C PREFERRED STOCK SHALL HAVE THE MEANINGS ASCRIBED TO
        THEM IN SUCH ARTICLES SUPPLEMENTARY, AS THE SAME MAY BE AMENDED FROM

        (k)     Exchange of Series C Preferred Units. The Corporation is hereby
expressly vested with authority (subject to the restrictions on ownership,
transfer and redemption of Series C Preferred Stock set forth in this Section 7)
to issue, and, so long as AMB Property Holding Corporation, a Maryland

        (m)     Severability. If any provision of this Section 7 or any
application of any such provision is determined to be invalid by any Federal or

provisions shall not be affected and other applications of such provision shall
be affected only to the extent necessary to comply with the determination of
such court.

        (n)     New York Stock Exchange. Nothing in this Section 7 shall
preclude the settlement of any transaction entered into through the facilities

            par value $.01 per share (the "Common Stock")filed on or about
            December 2, 1998

Ladies and Gentlemen:

      You have requested our opinion, as special Maryland corporate counsel to
AMB Property Corporation, a Maryland corporation (the "Company"), with respect
to the matters set forth below in connection with the registration of the
issuance and resale of the Shares, covered by the above-referenced Registration
Statement (the "Registration Statement"), filed by the Company with the
Securities and Exchange Commission (the "Commission") under the Securities Act
of 1933, as amended (the "Act"). The Shares are to be issued in exchange for up
to 2,542,163 units of limited partnership interest (the "Units") in AMB
Property, L.P., a Delaware limited partnership (the "Operating Partnership").
Unless otherwise defined herein, capitalized terms used herein shall have the
meanings assigned to them in the Registration Statement.

      In our capacity as special Maryland corporate counsel to the Company, and
as a basis for the opinion hereinafter set forth, we have examined originals, or
copies certified or otherwise identified to our satisfaction, of the following
documents (collectively, the "Documents"): The Registration Statement and the
related form of prospectus (the "Prospectus") included therein in the form in
which it was transmitted to the Commission under the Act; The charter of the
Company (the "Charter"), consisting of Articles of Incorporation filed with the
Maryland State Department of Assessments and Taxation (the "Department") on
November 24, 1997, and Articles Supplementary filed on July 23, 1998, November
12, 1998, and November __, 1998; The Bylaws of the Company (the "Bylaws"), which
were duly adopted by the Board of Directors of the Company on November 24, 1997;
Certain resolutions adopted and actions taken by the Board of Directors of the
Company (the "Board of Directors") on or before the date hereof and in full
force and effect on the date hereof including, but not limited to, those certain
resolutions adopted by the Board of Directors on November 24, 1997 relating to
the sale, issuance and registration of the Shares, certified as of a recent date
by an officer of the Company (the "Resolutions"); A status certificate of recent
date issued by the Department to the effect that the Company is duly
incorporated and existing under the laws of the State of Maryland; The form of
certificate representing a share of Common Stock, certified as of a recent date
by an officer of the Company; The Third Amended and Restated Partnership
Agreement of the Operating Partnership certified as of a recent date by an
Officer of the Company (the "Partnership Agreement"); A Certificate of Officers
of the Company of recent date to the effect that, among other things, the
Charter and Bylaws of the Company and the resolutions and actions by the Board
of Directors which we have examined are true, correct and complete, have not
been rescinded or modified and are in full force and effect on the date of such
certificate; and Such other documents and matters as we have deemed necessary or
appropriate to express the opinion set forth in this letter, subject to the
assumptions, limitations and qualifications stated herein.

      In expressing the opinion set forth below, we have assumed, and so far as
is known to us there are no facts inconsistent with, the following: (a) Each of
the parties (other than the Company) executing any of the Documents has duly and
validly executed and delivered each of the Documents to which such party is a
signatory, and such party's obligations set forth therein are legal, valid and
binding; (b) Each individual executing any of the Documents on behalf of a party
(other than the Company) is duly authorized to do so; (c) Each individual
executing any of the Documents, whether on behalf of such individual or another
person, is legally competent to do so; (d) All Documents submitted to us as
originals are authentic. The form and content of the Documents submitted to us
as unexecuted drafts do not differ in any respect relevant to this opinion from
the form and content of such Documents as executed and delivered. All Documents
submitted to us as certified or photostatic copies conform to the original
documents. All signatures on all such Documents are genuine. All public records
reviewed or relied upon by us or on our behalf are true and complete. All
statements and information contained in the Documents are true and complete.
There are no modifications of or amendments to the Documents, and there has been
no waiver of any of the provisions of the Documents, by action or omission of
the parties or otherwise; (e) The Resolutions adopted and the actions taken and
to be taken by the Board of Directors including, but not limited to, the
adoption of all resolutions and the taking of all action necessary to authorize
the issuance and sale of the Shares have occurred at duly called meetings at
which a quorum of the incumbent directors of the Company were or are present and
acting throughout, or by unanimous written consent of all incumbent directors,
all in accordance with the Charter and Bylaws of the Company and applicable law;
(f) The number of shares of Common Stock to be offered and sold under the
Registration Statement will not, in the aggregate, exceed the number of shares
of Common Stock authorized in the Charter of the Company, less the number of
shares of Common Stock authorized and reserved for issuance and/or issued and
outstanding on the date on which the Shares are authorized or the date on which
the Shares are issued and delivered, and none of the Shares will be issued, sold
or transferred in violation of the provisions of the Charter of the Company; (g)
The phrase "known to us" is limited to the actual knowledge, without independent
inquiry, of the lawyers at our firm who have performed legal services in
connection with the issuance of this opinion.

      Based upon the foregoing, and subject to the assumptions, limitations and
qualifications stated herein, it is our opinion that:

      1.    The Company is a corporation duly incorporated and existing under
            and by virtue of the laws of the State of Maryland and is in good
            standing with the SDAT.

      2.    The Shares are duly authorized and, upon issuance in accordance with
            the Prospectus, the Resolutions, the Partnership Agreement and the
            Charter, and upon due execution, countersignature and delivery of
            certificates representing the Shares, when and if delivered against
            payment of the consideration therefor as set by the Board of
            Directors, the Shares will be validly issued, fully paid and
            nonassessable.

      We consent to the filing of this opinion as an exhibit to the Registration
Statement and further consent to the filing of this opinion as an exhibit to
applications to the securities commissioners of the various states of the United
States for registration of the Securities. We also consent to the identification
of our firm as Maryland counsel to the Company in the section of the Prospectus
(which is a part of the Registration Statement) entitled "Legal Matters." In
giving these consents, we do not admit that we are within the category of
persons whose consent is required by Section 7 of the Act.

      This opinion is limited to the present corporate laws of the State of
Maryland and we express no opinion with respect to the laws of any other
jurisdiction. Furthermore, the opinions presented in this letter are limited to
the

matters specifically set forth herein and no other opinion shall be inferred
beyond the matters expressly set forth herein. Without limiting the generality
of the foregoing, we express no opinion with respect to any securities laws or
with respect to the action required for the Operating Partnership to authorize,
execute or deliver any of the Units or any other document, instrument or
agreement.

      The opinions set forth in this letter are rendered as of the date hereof
and are necessarily limited to laws now in effect and facts and circumstances
presently existing and brought to our attention. We assume no obligation to
supplement this opinion if any applicable law is changed after the date hereof
or if we become aware of any facts or circumstances which now exist or which
occur or arise in the future and may change the opinions expressed herein after
the date hereof.

      The opinions expressed in this letter are for your use and the use of your
securities counsel, Latham & Watkins, in connection with the filing of the
Registration Statement and the rendering of opinions by Latham & Watkins in
connection therewith, and may not be relied upon by you or Latham & Watkins for
any other purpose, without our prior written consent.

        Re:    AMB Property Corporation
               Registration Statement on Form S-3

Ladies and Gentlemen:

               We have acted as special counsel to AMB Property Corporation, a
Maryland corporation (the "Company"), in connection with the registration
statement on Form S-3 being filed by the Company on the date hereof with the
Securities and Exchange Commission in connection with the registration, under
the Securities Act of 1933, as amended, of 2,542,163 shares of the Company's
common stock, par value $.01 per share (together with all exhibits thereto and
documents incorporated by reference therein, the "Registration Statement").

               In our capacity as such counsel, we have made such legal and
factual examinations and inquiries, including an examination of originals or
copies certified or otherwise identified to our satisfaction of such documents,
corporate records and other instruments, as we have deemed necessary or
appropriate for purposes of this opinion. In our examination, we have assumed
the authenticity of all documents submitted to us as originals, the genuineness
of all signatures thereon,

the legal capacity of natural persons executing such documents and the
conformity to authentic original documents of all documents submitted to us as
copies.

               We are opining herein as to the effect on the subject transaction
only of the federal income tax laws of the United States and we express no
opinion with respect to the applicability thereto, or the effect thereon, of
other federal laws, the laws of any state or other jurisdiction or as to any
matters of municipal law or the laws of any other local agencies with any state.

               Based upon certain representations from the Company, including 
the facts set forth in the Registration Statement, it is our opinion that the
information in the Registration Statement set forth under the caption "Certain
Federal Income Tax Considerations," to the extent that it constitutes matters of
law, summaries of legal matters, documents or proceedings, or legal conclusions,
has been reviewed by us and is correct in all material respects.

               No opinion is expressed as to any matter not discussed herein.

               This opinion is only being rendered to you as of the date of this
letter, and we undertake no obligation to update this opinion subsequent to the
date hereof. This opinion is based on various statutory provisions, regulations
promulgated thereunder and interpretations thereof by the Internal Revenue
Service and the courts having jurisdiction over such matters, all of which are
subject to change either prospectively or retroactively. Also, any variation or
difference in the facts from those set forth in the Registration Statement may
affect the conclusions stated herein.

               This opinion is rendered to you and is solely for your benefit in
connection with the Registration Statement. We hereby consent to the filing of
this opinion as an exhibit to the Registration Statement. This opinion may not
be relied upon by you for any other purpose, or furnished to, quoted to or
relied upon by any other person, firm or corporation for any purpose, without
our prior written consent.

                                       Very truly yours,

shall be an amount which bears the same ratio to such beginning Gross Asset
Value as the Federal income tax depreciation, amortization or other cost
recovery deduction for such year or other period bears to such beginning
adjusted tax basis; provided, however, that if the Federal income tax

zero, Depreciation shall be determined with reference to such beginning Gross

per Partnership Unit for a Limited Partner which is not a PLP or a Performance
Partner. For purposes of (ii) above, it shall be assumed that the Limited
Partner has no special arrangements with the Partnership, other than as set
forth in this Agreement, which would cause its Capital Account per Partnership
Unit to be different from the Capital Account per Partnership Unit of other
Limited Partners who are not Performance Partners or PLPs. If the Partner
described in (ii) above does not exist, the amount used for purposes of (ii)
shall be the projected Capital Account balance per Partnership Unit for such
Partner, determined in the reasonable discretion of the General Partner. For
purposes of this definition, to the extent the Capital Account of a Partner
which owns both Common Units and Preference Units is being considered, such
Capital Account shall be equal to such Partner's Capital Account determined
without regard to the adjustments arising from or as a result of the acquisition
or ownership of Preference Units by such Partner.

on any securities exchange or the Nasdaq National Market, the closing price,
regular way, on such day, or if no such sale takes place on such day, the
average of the closing bid and asked prices on such day, (ii) if such shares are
not listed or admitted to trading on any securities exchange or the Nasdaq
National Market, the last reported sale price on such day or, if no sale takes
place on such day, the average of the closing bid and asked prices on such day,
as reported by a reliable quotation source designated by the General Partner or
(iii) if such shares are not listed or admitted to trading on any securities
exchange or the Nasdaq National Market and no such last reported sale price or

question, the Fair Market Value of such shares shall be determined by the
General Partner acting in good faith on the basis of such quotations and other
information as it considers, in its reasonable judgment, appropriate. In the
event the REIT Shares Amount for such shares includes rights that a holder of
such shares would be entitled to receive, then the Fair Market Value of such
rights shall be determined by the General Partner acting in good faith on the
basis of such quotations and other information as it considers, in its
reasonable judgment, appropriate; provided, that in connection with determining
the Deemed Value of the Partnership Interests for purposes of determining the
number of additional Partnership Units issuable upon a Capital Contribution
funded by an underwritten public offering of shares of capital stock of the
General Partner, the Fair Market Value of such shares shall be the public
offering price per share of such class of capital stock sold. Notwithstanding
the foregoing, the General Partner in its reasonable discretion may use a
different "Fair Market Value" for purposes of making the determinations under
subparagraph (ii) of the definition of "Gross Asset Value" and Section 4.3.E. in
connection with the contribution of Property to the Partnership by a
third-party, provided such value shall be based upon the value per REIT Share
(or per Partnership Unit) agreed upon by the General Partner and such
third-party for purposes of such contribution.

provided, that if the contributing Partner is the General Partner then, except
with respect to the General Partner's initial Capital Contribution which shall
be determined as set forth on Exhibit A, or capital contributions of cash, REIT
Shares or other shares of capital stock of the General Partner, the
determination of the fair market value of the contributed asset shall be
determined by (a) the price paid by the General Partner if the asset is acquired

                           Partnership by a new or existing Partner in exchange

                           the General Partner reasonably determines that such
                           adjustment is necessary or appropriate to reflect the
                           relative economic interests of the Partners in the
                           Partnership;

                  (b)      the distribution by the Partnership to a Partner of
                           more than a de minimis amount of Partnership property
                           as consideration for an interest in the Partnership
                           if the General Partner reasonably determines that
                           such adjustment is necessary or appropriate to
                           reflect the relative economic interests of the
                           Partners in the Partnership; the Partners agree that
                           such an adjustment is appropriate when the
                           Partnership effects a Redemption;

pursuant to this subparagraph (iv).

                  (v) If the Gross Asset Value of a Partnership asset has been

violation of, or a default under, any agreement by which such Partner or any of
such Partner's property is or are bound, or any statute, regulation, order or
other law to which such Partner is subject, (iii) such Partner is neither a
"foreign person" within the meaning of Section 1445(f) of the Code nor a
"foreign partner" within the meaning of Section 1446(e) of the Code and (iv)
this Agreement has been duly executed and delivered by such Partner and is
binding upon, and enforceable against, such Partner in accordance with its
terms.

                  B. Each Partner that is not an individual represents and
warrants to each other Partner that (i) its execution and delivery of this
Agreement and all transactions contemplated by this Agreement to be performed by
it have been duly authorized by all necessary action, including without
limitation, that of its general partner(s), committee(s), trustee(s),
beneficiaries, directors and/or stockholder(s), as the case may be, as required,
(ii) the consummation of such transactions shall not result in a breach or
violation of, or a default under, its certificate of limited partnership,
partnership agreement, trust agreement, limited liability company operating
agreement, charter or by-laws, as the case may be, any agreement by which such
Partner or any of such Partner's properties or any of its partners,
beneficiaries, trustees or stockholders, as the case may be, is or are bound, or
any statute, regulation, order or other law to which such Partner or any of its
partners, trustees, beneficiaries or stockholders, as the case may be, is or are
subject, (iii) such Partner is neither a "foreign person" within the meaning of
Section 1445(f) of the Code nor a "foreign partner" within the meaning of
Section 1446(e) of the Code and (iv) this Agreement has been duly executed and
delivered by such Partner and is binding upon, and enforceable against, such
Partner in accordance with its terms.

                  C. Each Partner represents, warrants and agrees that it has
acquired and continues to hold its interest in the Partnership for its own
account for investment only and not for the purpose of, or with a view toward,
the resale or distribution of all or any part thereof, nor with a view toward
selling or otherwise distributing such interest or any part thereof at any
particular time or under any predetermined circumstances. Each Partner further
represents and warrants that it is a sophisticated investor, able and accustomed
to handling sophisticated financial matters for itself, particularly real estate
investments, and that it has a sufficiently high net worth that it does not
anticipate a need for the funds it has invested in the Partnership in what it
understands to be a highly speculative and illiquid investment.

                  D. Each Partner further represents, warrants and agrees as
follows:

                           (i) Except as provided in Exhibit E, at any time such
         Partner actually or Constructively owns a 25% or greater capital
         interest or profits interest in the Partnership, it does not and will
         not, without the prior written consent of the General Partner, actually
         own or Constructively Own (a) with respect to any Tenant that is a
         corporation, any stock of such Tenant and (b) with respect to any
         Tenant that is not a corporation, any interests in either the assets or
         net profits of such Tenant.

                           (ii) Except as provided in Exhibit F, at any time
         such Partner actually or Constructively owns a 25% or greater capital
         interest or profits interest in the Partnership, it does not, and
         agrees that it will not without the prior written consent of the
         General Partner, actually own or Constructively Own, any stock in the
         General Partner, 



                                       23
<PAGE>   28

         other than any REIT Shares or other shares of capital stock of the
         General Partner such Partner may acquire (a) as a result of an exchange
         of Tendered Units pursuant to Section 8.6 or (b) upon the exercise of
         options granted or delivery of REIT Shares pursuant to any Stock
         Incentive Plan, in each case subject to the ownership limitations set
         forth in the General Partner's Charter.

                           (iii) Upon request of the General Partner, it will
         disclose to the General Partner the amount of REIT Shares or other
         shares of capital stock of the General Partner that it actually owns or
         Constructively Owns.

                           (iv) It understands that if, for any reason, (a) the
         representations, warranties or agreements set forth in Section 3.4.D(i)
         or (ii) are violated or (b) the Partnership's actual or Constructive
         Ownership of the REIT Shares or other shares of capital stock of the
         General Partner violates the limitations set forth in the Charter, then
         (x) some or all of the Redemption rights or rights to exchange
         Partnership Interests for Series B Preferred Shares of the Limited
         Partners may become non-exercisable, and (y) some or all of such shares
         owned by the Partners and/or some or all of the Partnership Interests
         owned by the Limited Partners may be automatically transferred to a
         trust for the benefit of a charitable beneficiary, as provided in the
         Charter and Exhibit J of this Agreement, respectively.

                  E. The representations and warranties contained in Sections
3.4.A, 3.4.B, 3.4.C and 3.4.D shall survive the execution and delivery of this
Agreement by each Partner and the dissolution and winding up of the Partnership.

                  F. Each Partner hereby acknowledges that no representations as
to potential profit, cash flows, funds from operations or yield, if any, in
respect of the Partnership or the General Partner have been made by any Partner
or any employee or representative or Affiliate of any Partner, and that
projections and any other information, including, without limitation, financial
and descriptive information and documentation, which may have been in any manner
submitted to such Partner shall not constitute any representation or warranty of
any kind or nature, express or implied.

                       Section 3.5. Certain ERISA Matters

                  Each Partner acknowledges that the Partnership is intended to
qualify as a "real estate operating company" (as such term is defined in the
Plan Asset Regulation). The General Partner will use its reasonable best efforts
to structure the investments in, relationships with and conduct with respect to
Properties and any other assets of the Partnership so that the Partnership will
be a "real estate operating company" (as such term is defined in the Plan Asset
Regulation).

                              CAPITAL CONTRIBUTIONS

                  Section 4.1. Capital Contributions of the Partners

                  At the time of their respective execution of this Agreement,
the Partners shall make or shall have made Capital Contributions as set forth in
Exhibit A to this Agreement. The Partners shall own Partnership Units of the
class and in the amounts set forth in Exhibit A and shall have a Percentage
Interest in the Partnership as set forth in Exhibit A, which Percentage Interest
shall be adjusted in Exhibit A from time to time by the General Partner to the
extent necessary to accurately reflect exchanges, redemptions, Capital
Contributions, the issuance of additional Partnership Units (including the
issuance of Performance Units pursuant to Section 4.3.F) or similar events
having an effect on a Partner's Percentage Interest. Except as required by law
or as otherwise provided in Sections 4.3, 4.4 and 10.5, no Partner shall be
required or permitted to make any additional Capital Contributions or loans to
the Partnership. Unless otherwise specified by the General Partner at the time
of the creation of any class of Partnership Interests, the corresponding class
of capital stock for any Partnership Units issued shall be REIT Shares.

                  Section 4.2. Loans by Third Parties

                  Subject to Section 4.3, the Partnership may incur Debt, or
enter into other similar credit, guarantee, financing or refinancing
arrangements for any purpose (including, without limitation, in connection with
any further acquisition of Properties) with any Person that is not the General
Partner upon such terms as the General Partner determines appropriate; provided,
that the Partnership shall not incur any Debt that is recourse to the General
Partner, except to the extent otherwise agreed to by the General Partner in its
sole discretion.

                  Section 4.3. Additional Funding and Capital Contributions

                  A. General. The General Partner may, at any time and from time
to time, determine that the Partnership requires additional funds ("Additional
Funds") for the acquisition of additional Properties or for such other
Partnership purposes as the General Partner may determine. Additional Funds may
be raised by the Partnership, at the election of the General Partner, in any
manner provided in, and in accordance with, the terms of this Section 4.3. No
Person shall have any preemptive, preferential or similar right or rights to
subscribe for or acquire any Partnership Interest, except as set forth in this
Section 4.3.

                  B. General Partner Loans. The General Partner may enter into a
Funding Debt, including, without limitation, Funding Debt that is convertible
into REIT Shares, and lend the Additional Funds to the Partnership (a "General
Partner Loan"); provided, however, that the General Partner shall not be
obligated to lend the net proceeds of any Funding Debt to the Partnership in a
manner that would be inconsistent with the General Partner's ability to remain
qualified as a REIT. If the General Partner enters into such a Funding Debt, the
General Partner Loan will consist of the net proceeds from such Funding Debt and
will be on comparable terms and conditions, including interest rate, repayment
schedule and costs and expenses, as shall be applicable with respect to or
incurred in connection with such Funding Debt.



                                       25
<PAGE>   30

                  C. Issuance of Additional Partnership Interests. The General
Partner may raise all or any portion of the Additional Funds by accepting
additional Capital Contributions of cash. The General Partner may also accept
additional Capital Contributions of real property or other non-cash assets. In
connection with any such additional Capital Contributions (of cash or property),
and subject to Section 17.6 hereof, the General Partner is hereby authorized to
cause the Partnership from time to time to issue to Partners (including the
General Partner) or other Persons (including, without limitation, in connection
with the contribution of property to the Partnership) additional Partnership
Units or other Partnership Interests in one or more classes, or one or more
series of any of such classes, with such designations, preferences and relative,
participating, optional or other special rights, powers, and duties, including
rights, powers, and duties senior to then existing Limited Partnership
Interests, all as shall be determined by the General Partner in its sole and
absolute discretion subject to Delaware law, and as set forth by amendment to
this Agreement, including without limitation: (i) the allocations of items of
Partnership income, gain, loss, deduction, and credit to such class or series of
Partnership Interests; (ii) the right of each such class or series of
Partnership Interests to share in Partnership distributions; (iii) the rights of
each such class or series of Partnership Interests upon dissolution and
liquidation of the Partnership; and (iv) the right to vote, including, without
limitation, the limited partner approval rights set forth in Section 11.2.A;
provided, that no such additional Partnership Units or other Partnership
Interests shall be issued to the General Partner unless either (a) the
additional Partnership Interests are issued in connection with the grant, award,
or issuance of shares of the General Partner pursuant to Section 4.3.D below,
which shares have designations, preferences, and other rights (except voting
rights) such that the economic interests attributable to such shares are
substantially similar to the designations, preferences and other rights of the
additional Partnership Interests issued to the General Partner in accordance
with this Section 4.3.C or (b) the additional Partnership Interests are issued
to all Partners holding Partnership Interests in the same class in proportion to
their respective Percentage Interests in such class. In the event that the
Partnership issues additional Partnership Interests pursuant to this Section
4.3.C, the General Partner shall make such revisions to this Agreement
(including but not limited to the revisions described in Sections 5.4, 6.2.C,
and 8.6) as it determines are necessary to reflect the issuance of such
additional Partnership Interests.

                  D. Issuance of REIT Shares or Other Securities by the General
Partner. The General Partner shall not issue any additional REIT Shares (other
than REIT Shares issued pursuant to Section 8.6 or pursuant to a dividend or
distribution (including any stock split) of REIT Shares to all of its
stockholders or all of its stockholders who hold a class of stock of the General
Partner), other shares of capital stock of the General Partner (other than in
connection with the acquisition of Partnership Interests in exchange for capital
stock of the General Partner which corresponds in ranking to the Partnership's
Partnership Interests being acquired) or New Securities unless the General
Partner shall make a Capital Contribution of the net proceeds (including,
without limitation, cash and Properties) from the issuance of such additional
REIT Shares, other shares of capital stock or New Securities, as the case may
be, and from the exercise of the rights contained in such additional New
Securities, as the case may be. The General Partner's Capital Account shall be
increased by the amount of cash or the value of Properties so contributed.



                                       26
<PAGE>   31

                  E. Percentage Interest Adjustments in the Case of Capital
Contributions for Partnership Units. Upon the acceptance of additional Capital
Contributions in exchange for any class or series of Partnership Units, the
Percentage Interest related thereto shall be equal to a fraction, the numerator
of which is equal to the amount of cash and the Agreed Value of the Properties
contributed as of the Business Day immediately preceding the date on which the
additional Capital Contributions are made (an "Adjustment Date") and the
denominator of which is equal to the sum of (i) the Deemed Value of the
Partnership Interests of such class or series (computed as of the Business Day
immediately preceding the Adjustment Date) plus (ii) the aggregate amount of
cash and the Agreed Value of the Property contributed to the Partnership on such
Adjustment Date in respect of such class or series of Partnership Interests. The
Percentage Interest of each other Partner holding Partnership Interests of such
class or series not making a full pro rata Capital Contribution shall be
adjusted to equal a fraction, the numerator of which is equal to the sum of (i)
the Deemed Partnership Interest Value of such Limited Partner in respect of such
class or series (computed as of the Business Day immediately preceding the
Adjustment Date) plus (ii) the amount of cash and the Agreed Value of the
Property contributed by such Partner to the Partnership in respect of such class
or series as of such Adjustment Date, and the denominator of which is equal to
the sum of (a) the Deemed Value of the Partnership Interests of such class
(computed as of the Business Day immediately preceding the Adjustment Date),
plus (b) the aggregate amount of cash and the Agreed Value of the Property
contributed to the Partnership on such Adjustment Date in respect of such class
or series. Notwithstanding the foregoing, solely for purposes of calculating a
Partner's Percentage Interest pursuant to this Section 4.3.E, (i) in the case of
cash Capital Contributions by the General Partner, such Capital Contributions
will be deemed to equal the cash contributed by the General Partner plus, in the
case of cash contributions funded by an offering of REIT Shares or other shares
of capital stock of the General Partner, the offering costs attributable to the
cash contributed to the Partnership, and (ii) in the case of the contribution of
Properties (or any portion thereof) by the General Partner which were acquired
by the General Partner in exchange for REIT Shares immediately prior to such
contribution, the General Partner shall be issued a number of Partnership Units
equal to the number of REIT Shares issued by the General Partner in exchange for
such Properties, the Partnership Units held by the other Partners shall not be
adjusted, and the Partners' Percentage Interests shall be adjusted accordingly.
The General Partner shall promptly give each Partner written notice of its
Percentage Interest, as adjusted.

                  F. Issuance of Performance Units to the PLPs. Performance
Investors may be required pursuant to the terms of the Escrow Agreements to
transfer all or a portion of their Performance Shares to the General Partner or
the Partnership (as applicable). To the extent Performance Shares (i.e., REIT
Shares) are transferred by Performance Investors to the General Partner pursuant
to the Escrow Agreements, the number of Partnership Units held by the General
Partner shall be automatically reduced by such amount on such date. To the
extent Performance Shares (i.e., Partnership Units) are transferred by
Performance Investors to the Partnership pursuant the Escrow Agreements, the
number of Partnership Units held by each such Performance Investor shall be
automatically reduced by such amount on such date. To the extent the Partnership
Units held by the General Partner or Performance Investors are reduced as set
forth in the preceding two sentences, the Partnership shall immediately issue an
equal number of Performance Units to the Persons listed on Schedule G-1 and
Schedule G-2 to Exhibit G in accordance with the allocations set forth on
Exhibit G. The adjustments in the number of 



                                       27
<PAGE>   32

Partnership Units held by the Performance Partners and the PLPs set forth above
shall have no effect on each such Partners' Capital Account in the Partnership
(except with respect to subsequent allocations of items of Partnership income,
gain, loss, deduction, and credit made to such Partners and possibly with
respect to the reissuance of a Performance Unit subsequent to its forfeiture by
a PLP) and no PLP shall have an obligation to make a contribution to the capital
of the Partnership in connection with the issuance of Performance Units.

                  Section 4.4. Stock Incentive Plan

                  If at any time or from time to time the General Partner sells
or issues REIT Shares pursuant to any Stock Incentive Plan, the General Partner
shall contribute any proceeds therefrom to the Partnership as an additional
Capital Contribution and shall receive an amount of additional Partnership Units
equal to the number of REIT Shares so sold or issued. The General Partner's
Capital Account shall be increased by the amount of cash so contributed.

                  Section 4.5. No Preemptive Rights

                  Except to the extent expressly granted by the Partnership
pursuant to another agreement, no Person shall have any preemptive, preferential
or other similar right with respect to (i) additional Capital Contributions or
loans to the Partnership or (ii) issuance or sale of any Partnership Units or
other Partnership Interests.

                  Section 4.6. Other Contribution Provisions

                  In the event that any Partner is admitted to the Partnership
and is given (or is treated as having received) a Capital Account in exchange
for services rendered to the Partnership, such transaction shall be treated by
the Partnership and the affected Partner as if the Partnership had compensated
such Partner in cash, and the Partner had contributed such cash to the capital
of the Partnership. In addition, with the consent of the General Partner, in its
sole discretion, one or more Limited Partners may enter into contribution
agreements with the Partnership which have the effect of providing a guarantee
of certain obligations of the Partnership.

                                   ARTICLE 5.
                                  DISTRIBUTIONS

         Section 5.1. Requirement and Characterization of Distributions

                  The General Partner shall cause the Partnership to distribute
all, or such portion as the General Partner may in its discretion determine,
Available Cash generated by the Partnership (i) first, to the extent that the
amount of cash distributed with respect to any Partnership Interests that are
entitled to any preference in distribution for any prior distribution period was
less than the required distribution for such outstanding Partnership Interests
for such prior distribution period, and to the extent such deficiency has not
been subsequently distributed pursuant to this Section 5.1 (a "Preferred
Distribution Shortfall"), in accordance with the rights of such class of
Partnership Interests (and within such class, pro rata in proportion to the
respective Percentage Interests on the applicable 



                                       28
<PAGE>   33

record date) and to the Partners who are Partners on the applicable record date
with respect to such distribution, (ii) second, with respect to any Partnership
Interests that are entitled to any preference in distribution, in accordance
with the rights of such class of Partnership Interests (and within such class,
pro rata in proportion to the respective Percentage Interests on the applicable
record date) and (iii) third, with respect to Partnership Interests that are not
entitled to any preference in distribution, pro rata to each such class on a
quarterly basis and in accordance with the terms of such class to Partners who
are Partners of such class on the Partnership Record Date with respect to such
distribution (and within each such class, pro rata in proportion with the
respective Percentage Interests on such Partnership Record Date). Except as
expressly provided for in Article 16 with respect to the Series A Preferred
Units, Article 17 with respect to the Series B Preferred Units and in an
agreement, if any, entered into in connection with the creation of a new class
of Partnership Interests in accordance with Article 4, no Partnership Interest
shall be entitled to a distribution in preference to any other Partnership
Interest. The General Partner shall take such reasonable efforts, as determined
by it in its sole and absolute discretion and consistent with its qualification
as a REIT, to cause the Partnership to distribute sufficient amounts to enable
the General Partner, for so long as the General Partner has determined to
qualify as a REIT, to pay stockholder dividends that will (a) satisfy the
requirements for qualifying as a REIT under the Code and Regulations ("REIT
Requirements") and (b) except to the extent otherwise determined by the General
Partner, avoid any Federal income or excise tax liability of the General
Partner, except to the extent that a distribution pursuant to clause (b) would
prevent the Partnership from making a distribution to the holders of Series B
Preferred Units in accordance with Section 17.3.

                  Section 5.2. Distributions in Kind

                  Except as expressly provided herein, no right is given to any
Partner to demand and receive property other than cash. The General Partner may
determine, in its sole and absolute discretion, to make a distribution in kind
to the Partners of Partnership assets, and such assets shall be distributed in
such a fashion as to ensure that the fair market value is distributed and
allocated in accordance with Articles 5, 6 and 10; provided, however, that, in
such case, the General Partners shall distribute only cash to the Series B
Limited Partners.

                  Section 5.3. Distributions Upon Liquidation

                  Proceeds from a Terminating Transaction shall be distributed
to the Partners in accordance with Section 13.2.

                  Section 5.4. Distributions to Reflect Issuance of Additional
Partnership Interests

                  In the event that the Partnership issues additional
Partnership Interests (other than Performance Units, which shall receive
distributions as set forth in Section 5.1) to the General Partner or any
Additional Limited Partner pursuant to Section 4.3.C or 4.4, the General Partner
shall make such revisions to this Article 5 as it determines are necessary to
reflect the issuance of such additional Partnership Interests. In the absence of
any agreement to the contrary, an Additional Limited Partner shall be entitled
to the distributions set forth in Section 5.1 (without regard to this Section
5.4) with respect to the quarter during which the closing of its contribution to
the Partnership occurs, multiplied by a fraction the numerator of which is the
number of days 



                                       29
<PAGE>   34

from and after the date of such closing through the end of the applicable
quarter, and the denominator of which is the total number of days in such
quarter.

                  Section 5.5 Character of PLP Distributions

                  Distributions to each PLP pursuant to this Agreement shall be
advances or drawings of money or property against such Partner's distributive
share of Net Income (or items thereof) as described in Treasury Regulation
Section 1.731-1(a)(1)(ii).

                                   ARTICLE 6.
                                   ALLOCATIONS

                  Section 6.1. Timing and Amount of Allocations of Net Income
and Net Loss

                  Net Income and Net Loss of the Partnership shall be determined
and allocated with respect to each fiscal year of the Partnership as of the end
of each such year. Subject to the other provisions of this Article 6, an
allocation to a Partner of a share of Net Income or Net Loss shall be treated as
an allocation of the same share of each item of income, gain, loss or deduction
that is taken into account in computing Net Income or Net Loss.

                  Section 6.2. General Allocations

                  A. In General. Except as otherwise provided in this Article 6,
Net Income and Net Loss allocable with respect to a class of Partnership
Interests, shall be allocated to each of the Partners holding such class of
Partnership Interests in accordance with their respective Percentage Interest of
such class.

                  B.1. Net Income. Except as provided in Section 6.2.B.3, Net
Income for any Partnership Year shall be allocated in the following manner and
order of priority:

                  (a)      First, 100% to the General Partner in an amount equal
                           to the remainder, if any, of the cumulative Net
                           Losses allocated to the General Partner pursuant to
                           Section 6.2.B.2(d) for all prior Partnership Years
                           minus the cumulative Net Income allocated to the
                           General Partner pursuant to this Section 6.2.B.1(a)
                           for all prior Partnership Years;

                  (b)      Second, 100% to each Limited Partner in an amount
                           equal to the remainder, if any, of the cumulative Net
                           Losses allocated to each such Limited Partner
                           pursuant to Section 6.2.B.2(c) for all prior
                           Partnership Years minus the cumulative Net Income
                           allocated to such Limited Partner pursuant to this
                           Section 6.2.B.1(b) for all prior Partnership Years;

                  (c)      Third, 100% to the General Partner and any other
                           Preferred Partners in an amount equal to the
                           remainder, if any, of the cumulative Net Losses
                           allocated to such Partners pursuant to Section
                           6.2.B.2(b) for all prior

                           Partnership Years minus the cumulative Net Income
                           allocated to each Partner pursuant to this Section

                           redemption, to the extent Series A Preferred Units

                           redemption, to the extent Series B Preferred Units
                           are redeemed during such year, over (ii) the
                           cumulative Net Income allocated to the General
                           Partner or such Preferred Partner, as applicable,

                           Percentage Interests in the Common Units.

                  To the extent the allocations of Net Income set forth above in
any paragraph of this Section 6.2.B.1 are not sufficient to entirely satisfy the
allocation set forth in such paragraph, such allocation shall be made in
proration to the total amount that would have been allocated pursuant to such
paragraph without regard to such shortfall.

                  B.2. Net Losses. Except as provided in Section 6.2.B.3, Net
Losses for any Partnership Year shall be allocated in the following manner and

                           Percentage Interests in the Common Units (to the
                           extent consistent with this Section 6.2.B.2(a)) until
                           the Adjusted Capital Account (ignoring for this
                           purpose any amounts a Partner is obligated to
                           contribute to the capital of the Partnership or is
                           deemed obligated to contribute pursuant to
                           Regulations Section 1.704-1(b)(2)(ii)(c)(2) and
                           ignoring the Partner's Series A Preferred Capital and
                           Series B Preferred Capital) of each such Partner is
                           zero;

                  (b)      Second, 100% to the General Partner and any other
                           Preferred Partners, pro rata to each such Partner's

                           Regulations Section 1.704-1(b)(2)(ii)(c)(2)), until
                           the Adjusted Capital Account (as so modified) of each
                           such Partner is zero;

                  (c)      Third, 100% to the Limited Partners to the extent of,
                           and in proportion to, the positive balance (if any)
                           in their Adjusted Capital Accounts; and

                  (d)      Fourth, 100% to the General Partner.

                  B.3.     Terminating Capital Transactions.

                  (a)      If no Performance Units are outstanding at the time
                           of a Terminating Capital Transaction, any Net Income
                           attributable to such Terminating Capital Transaction
                           shall first be allocated to the General Partner in an
                           amount equal to the Offering Costs, to the extent the
                           General Partner's Capital Account has not previously
                           been adjusted to account for such amounts.

                  (b)      If Performance Units are outstanding at the time of a
                           Terminating Capital Transaction

                           (1)      any Net Income attributable to such
                                    Terminating Capital Transaction shall be
                                    allocated as follows: such Net Income shall
                                    first be tentatively allocated solely as an
                                    interim step in calculating final
                                    allocations pursuant to this Section
                                    6.2.B.3(b)(1), among the Partners in
                                    accordance with Section 6.2.B.3(a), Section
                                    6.2.A and Section 6.2.B.1. Then the amount
                                    so tentatively allocated to each Performance
                                    Partner, to the extent of each such
                                    Performance Partner's Excess Performance
                                    Capital, shall instead be allocated to the
                                    PLPs, pro rata to the number of Performance
                                    Units held by each PLP.

                           (2)      any Net Loss attributable to such
                                    Terminating Capital Transaction shall be
                                    allocated as follows: such Net Loss shall
                                    first be tentatively allocated, solely as an
                                    interim step in calculating final
                                    allocations pursuant to this Section
                                    6.2.B.3(b)(2), among the Partners in
                                    accordance with Section 6.2.A and Section
                                    6.2.B.2. Then the amount so tentatively
                                    allocated to the PLPs shall instead be
                                    allocated to the Performance Partners to the
                                    extent of the aggregate Excess Performance
                                    Capital of the Performance Partners. Any
                                    amounts so allocated away from the PLPs
                                    shall be done on a basis which is
                                    proportionate to each PLP's Performance
                                    Units. Any amounts so allocated to the
                                    Performance Partners shall be done on a
                                    basis which is proportionate to each
                                    Performance Partner's Excess Performance
                                    Capital.

                  C. Allocations to Reflect Issuance of Additional Partnership
Interests. In the event that the Partnership issues additional Partnership
Interests to the General Partner or any 



                                       32
<PAGE>   37

Additional Limited Partner pursuant to Section 4.3 or 4.4, the General Partner
shall make such revisions to this Section 6.2 or to Section 12.2.B as it
determines are necessary to reflect the terms of the issuance of such additional
Partnership Interests, including making preferential allocations to certain
classes of Partnership Interests, subject to the terms of the Series A Preferred
Units and the Series B Preferred Units. In addition, for any quarter in which
Performance Units were issued, Net Income and Net Loss relating to such units
shall be allocated among (i) the PLPs who received such units and (ii) the
Performance Partners who returned the corresponding Partnership Units to the
Partnership, in accordance with any method selected by the General Partner which
is permitted under Section 706 of the Code.

                  Section 6.3. Additional Allocation Provisions

                  Notwithstanding the foregoing provisions of this Article 6:

                  A. Regulatory Allocations.

                           (i) Minimum Gain Chargeback. Except as otherwise
         provided in Regulations Section 1.704-2(f), notwithstanding the
         provisions of Section 6.2, or any other provision of this Article 6, if
         there is a net decrease in Partnership Minimum Gain during any fiscal
         year, each Partner shall be specially allocated items of Partnership
         income and gain for such year (and, if necessary, subsequent years) in
         an amount equal to such Partner's share of the net decrease in
         Partnership Minimum Gain, as determined under Regulations Section
         1.704-2(g). Allocations pursuant to the previous sentence shall be made
         in proportion to the respective amounts required to be allocated to
         each Partner pursuant thereto. The items to be allocated shall be
         determined in accordance with Regulations Sections 1.704-2(f)(6) and
         1.704-2(j)(2). This Section 6.3.A(i) is intended to qualify as a
         "minimum gain chargeback" within the meaning of Regulation Section
         1.704-2(f) which shall be controlling in the event of a conflict
         between such Regulation and this Section 6.3.A(i).

                           (ii) Partner Minimum Gain Chargeback. Except as
         otherwise provided in Regulations Section 1.704-2(i)(4), and
         notwithstanding the provisions of Section 6.2, or any other provision
         of this Article 6 (except Section 6.3.A(i)), if there is a net decrease
         in Partner Minimum Gain attributable to a Partner Nonrecourse Debt
         during any fiscal year, each Partner who has a share of the Partner
         Minimum Gain attributable to such Partner Nonrecourse Debt, determined
         in accordance with Regulations Section 1.704-2(i)(5), shall be
         specially allocated items of Partnership income and gain for such year
         (and, if necessary, subsequent years) in an amount equal to such
         Partner's share of the net decrease in Partner Minimum Gain
         attributable to such Partner Nonrecourse Debt, determined in accordance
         with Regulations Section 1.704-2(i)(4). Allocations pursuant to the
         previous sentence shall be made in proportion to the respective amounts
         required to be allocated to each General Partner and Limited Partner
         pursuant thereto. The items to be so allocated shall be determined in
         accordance with Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2).
         This Section 6.3.A(ii) is intended to qualify as a "chargeback of
         partner nonrecourse debt minimum gain" within the meaning of Regulation
         Section 



                                       33
<PAGE>   38

         1.704-2(i) which shall be controlling in the event of a conflict
         between such Regulation and this Section 6.3.A(ii).

                           (iii) Nonrecourse Deductions and Partner Nonrecourse
         Deductions. Any Nonrecourse Deductions for any fiscal year shall be
         specially allocated to the Partners in accordance with their respective
         Percentage Interest in Common Units. Any Partner Nonrecourse Deductions
         for any fiscal year shall be specially allocated to the Partner(s) who
         bears the economic risk of loss with respect to the Partner Nonrecourse
         Debt to which such Partner Nonrecourse Deductions are attributable, in
         accordance with Regulations Sections 1.704-2(b)(4) and 1.704-2(i).

                           (iv) Qualified Income Offset. If any Partner
         unexpectedly receives an adjustment, allocation or distribution
         described in Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6),
         items of Partnership income and gain shall be allocated, in accordance
         with Regulations Section 1.704-1(b)(2)(ii)(d), to the Partner in an
         amount and manner sufficient to eliminate, to the extent required by
         such Regulations, the Adjusted Capital Account Deficit of the Partner
         as quickly as possible provided that an allocation pursuant to this
         Section 6.3.A(iv) shall be made if and only to the extent that such
         Partner would have an Adjusted Capital Account Deficit after all other
         allocations provided in this Article 6 have been tentatively made as if
         this Section 6.3.A(iv) were not in the Agreement. It is intended that
         this Section 6.3.A(iv) qualify and be construed as a "qualified income
         offset" within the meaning of Regulations 1.704-1(b)(2)(ii)(d), which
         shall be controlling in the event of a conflict between such
         Regulations and this Section 6.3.A(iv).

                           (v) Gross Income Allocation. In the event any Partner
         has a deficit Capital Account at the end of any fiscal year which is in
         excess of the sum of (a) the amount (if any) such Partner is obligated
         to restore to the Partnership and (b) the amount such Partner is deemed
         to be obligated to restore pursuant to Regulations Section
         1.704-1(b)(2)(ii)(c) or the penultimate sentences of Regulations
         Sections 1.704-2(g)(1) and 1.704-2(i)(5), each such Partner shall be
         specially allocated items of Partnership income and gain in the amount
         of such excess as quickly as possible; provided, that an allocation
         pursuant to this Section 6.3.A(v) shall be made if and only to the
         extent that such Partner would have a deficit Capital Account in excess
         of such sum after all other allocations provided in this Article 6 have
         been tentatively made as if this Section 6.3.A(v) and Section 6.3.A(iv)
         were not in the Agreement.

                           (vi) Limitation on Allocation of Net Loss. To the
         extent any allocation of Net Loss would cause or increase an Adjusted
         Capital Account Deficit as to any Partner, such allocation of Net Loss
         shall be reallocated among the other Partners in accordance with their
         respective Percentage Interests in Common Units, subject to the
         limitations of this Section 6.3.A(vi).

                           (vii) Section 754 Adjustment. To the extent an
         adjustment to the adjusted tax basis of any Partnership asset pursuant
         to Code Section 734(b) or Code Section 743(b) is required, pursuant to
         Regulations Section 1.704-1(b)(2)(iv)(m)(2) or 



                                       34
<PAGE>   39

         Regulations Section 1.704-1(b)(2)(iv)(m)(4), to be taken into account
         in determining Capital Accounts as the result of a distribution to a
         Partner in complete liquidation of his interest in the Partnership, the
         amount of such adjustment to the Capital Accounts shall be treated as
         an item of gain (if the adjustment increases the basis of the asset) or
         loss (if the adjustment decreases such basis) and such gain or loss
         shall be specially allocated to the Partners in accordance with their
         interests in the Partnership in the event that Regulations Section
         1.704-1(b)(2)(iv)(m)(2) applies, or to the Partners to whom such
         distribution was made in the event that Regulations Section
         1.704-1(b)(2)(iv)(m)(4) applies.

                           (viii) Curative Allocation. The allocations set forth
         in Sections 6.3.A(i), (ii), (iii), (iv), (v), (vi), and (vii) (the
         "Regulatory Allocations") are intended to comply with certain
         regulatory requirements, including the requirements of Regulations
         Sections 1.704-1(b) and 1.704-2. Notwithstanding the provisions of
         Sections 6.1 and 6.2, the Regulatory Allocations shall be taken into
         account in allocating other items of income, gain, loss and deduction
         among the Partners so that, to the extent possible, the net amount of
         such allocations of other items and the Regulatory Allocations to each
         Partner shall be equal to the net amount that would have been allocated
         to each such Partner if the Regulatory Allocations had not occurred.

                  B. For purposes of determining a Partner's proportional share
of the "excess nonrecourse liabilities" of the Partnership within the meaning of
Regulations Section 1.752-3(a)(3), each Partner's interest in Partnership
profits shall be such Partner's Percentage Interest in Common Units.

                  Section 6.4. Tax Allocations

                  A. In General. Except as otherwise provided in this Section
6.4, for income tax purposes each item of income, gain, loss and deduction
(collectively, "Tax Items") shall be allocated among the Partners in the same
manner as its correlative item of "book" income, gain, loss or deduction is
allocated pursuant to Sections 6.2 and 6.3.

                  B. Allocations Respecting Section 704(c) Revaluations.
Notwithstanding Section 6.4.A, Tax Items with respect to Partnership property
that is contributed to the Partnership by a Partner shall be shared among the
Partners for income tax purposes pursuant to Regulations promulgated under
Section 704(c) of the Code, so as to take into account the variation, if any,
between the basis of the property to the Partnership and its initial Gross Asset
Value. With respect to Partnership property that is initially contributed to the
Partnership upon its formation pursuant to Section 4.1, such variation between
basis and initial Gross Asset Value shall be taken into account under the
"traditional method" as described in Regulations Section 1.704-3(b). With
respect to properties subsequently contributed to the Partnership, the
Partnership shall account for such variation under any method approved under

Partner is authorized to execute, deliver and perform the above-mentioned
agreements and transactions on behalf of the Partnership without any further

this Agreement (except as provided in Section 7.3), the Act or any applicable
law, rule or regulation. The execution, delivery or performance by the General
Partner or the 



                                       38
<PAGE>   43

Partnership of any agreement authorized or permitted under this Agreement shall
not constitute a breach by the General Partner of any duty that the General
Partner may owe the Partnership or the Limited Partners or any other Persons
under this Agreement or of any duty stated or implied by law or equity.

                  C. At all times from and after the date hereof, the General
Partner may cause the Partnership to obtain and maintain (i) casualty, liability
and other insurance (including, without limitation, earthquake insurance) on the
properties of the Partnership and (ii) liability insurance for the Indemnities
hereunder.

                  D. At all times from and after the date hereof, the General
Partner may cause the Partnership to establish and maintain working capital and
other reserves in such amounts as the General Partner, in its sole and absolute
discretion, deems appropriate and reasonable from time to time.

                  E. In exercising its authority under this Agreement, the
General Partner may, but other than as set forth in the following sentence and
as expressly set forth in the agreements listed on Exhibit I hereto, shall be
under no obligation to, take into account the tax consequences to any Partner
(including the General Partner) of any action taken by the General Partner. The
General Partner, on behalf of the Partnership, shall use commercially reasonable
efforts to cooperate with the Limited Partners to minimize any taxes payable in
connection with any sale, exchange or any other disposition of assets of the
Partnership. The General Partner and the Partnership shall not have liability to
a Limited Partner under any circumstances as a result of an income tax liability
incurred by such Limited Partner as a result of an action (or inaction) by the
General Partner pursuant to its authority under this Agreement.

                  F. Except as otherwise provided herein, to the extent the
duties of the General Partner require expenditures of funds to be paid to third
parties, the General Partner shall not have any obligations hereunder except to
the extent that Partnership funds are reasonably available to it for the
performance of such duties, and nothing herein contained shall be deemed to
authorize or require the General Partner, in its capacity as such, to expend its
individual funds for payment to third parties or to undertake any individual
liability or obligation on behalf of the Partnership.

                  Section 7.2. Certificate of Limited Partnership

                  To the extent that such action is determined by the General
Partner to be reasonable and necessary or appropriate, the General Partner shall
file amendments to and restatements of the Certificate and do all the things to
maintain the Partnership as a limited partnership (or a partnership in which the
limited partners have limited liability) under the laws of the State of Delaware
and to maintain the Partnership's qualification to do business as a foreign
limited partnership in each other state, the District of Columbia or other
jurisdiction, in which the Partnership may elect to do business or own property.
Subject to the terms of Section 8.5.A(iv), the General Partner shall not be
required, before or after filing, to deliver or mail a copy of the Certificate
or any amendment thereto to any Limited Partner. The General Partner shall use
all reasonable efforts to cause to be filed such other certificates or documents
as may be reasonable and necessary or appropriate for the formation,
continuation, qualification and 



                                       39
<PAGE>   44

operation of a limited partnership (or a partnership in which the limited
partners have limited liability) in the State of Delaware, and any other state,
or the District of Columbia or other jurisdiction, in which the Partnership may
elect to do business or own property.

                           receipt of Performance Units);

                  (iv)     perform any act that would subject a Limited Partner

                           agreement that prohibits or restricts, or has the
                           effect of prohibiting or restricting, the ability of
                           a Limited Partner to exercise its rights to a
                           Redemption in full, except with the written consent
                           of such Limited Partner.

                  B. The General Partner shall not, without the prior Consent of
the Partners (in addition to any Consent of the Limited Partners required by any
other provision hereof), undertake, on behalf of the Partnership, any of the
following actions or enter into any transaction which would have the effect of
such transactions:

                  (i)      except as provided in Section 7.3.D below, amend,

                           the Partnership;

Section 13.1 (other than Section 13.1.F), the General Partner shall not, without
the prior Consent of the Limited Partners, undertake, on behalf of the

or other disposition of all or substantially all of the Partnership's assets in
a single transaction or a series of related transactions.

                  D. Notwithstanding Sections 7.3.B and 7.3.C, but subject to
Section 7.3.E, the General Partner shall have the power, without the Consent of
the Partners, to amend this Agreement as may be required to facilitate or
implement any of the following purposes:

                  (i)      to add to the obligations of the General Partner or
                           surrender any right or power granted to the General
                           Partner or any Affiliate of the General Partner for
                           the benefit of the Limited Partners;

                  (ii)     to reflect the issuance of additional Partnership
                           Interests pursuant to Sections 4.3.C, 4.3.F and 4.4,
                           or the admission, substitution, termination,
                           reduction in Partnership Units or withdrawal of
                           Partners in accordance with this Agreement (which may
                           be effected through the replacement of Exhibit A with
                           an amended Exhibit A);

                  (iii)    to set forth or amend the designations, rights,
                           powers, duties, and preferences of the holders of any
                           additional Partnership Interests issued pursuant to
                           Article 4;

                  (iv)     to reflect a change that is of an inconsequential
                           nature and does not adversely affect the Limited
                           Partners in any material respect, or to cure any
                           ambiguity in, correct or supplement any provision, or
                           make other changes with respect to matters arising
                           under, this Agreement that will not be inconsistent
                           with law or with the provisions of this Agreement;

                  (v)      to satisfy any requirements, conditions, or
                           guidelines contained in any order, directive,
                           opinion, ruling or regulation of a Federal, state of
                           local agency or contained in Federal, state or local
                           law.

                  (vi)     to reflect such changes as are reasonably necessary
                           for the General Partner to maintain its status as a
                           REIT, including changes which may be necessitated due
                           to a change in applicable law (or an authoritative
                           interpretation thereof) or a ruling of the IRS; and

                  (vii)    to modify, as set forth in the definition of "Capital
                           Account," the manner in which Capital Accounts are
                           computed.



                                       41

The General Partner will provide notice to the Limited Partners when any action
under this Section 7.3.D is taken.

                  E. Notwithstanding Sections 7.3.B, 7.3.C and 7.3.D, this
Agreement shall not be amended, and no action may be taken by the General
Partner, including in either case through merger or sale of assets of the
Partnership or otherwise, without the Consent of each Common Limited Partner or
Preferred Limited Partner adversely affected if such amendment or action would
(i) convert a Limited Partner's interest in the Partnership into a general
partner's interest (except as the result of the General Partner acquiring such
interest), (ii) modify the limited liability of a Limited Partner, (iii) alter
rights of the Partner to receive distributions pursuant to Article 5, Section
13.2.A(4) or Article 16 or the allocations specified in Article 6 (except as
permitted pursuant to Section 4.3 and Section 7.3.D), (iv) alter or modify the
rights to a Redemption or the REIT Shares Amount as set forth in Section 8.6,
and related definitions hereof, (v) alter the Redemption or exchange rights as
set forth in Sections 17.5 and 17.8 hereof, respectively, or (vi) amend this
Section 7.3.E. Further, no amendment may alter the restrictions on the General
Partner's authority set forth elsewhere in this Section 7.3 without the Consent
specified in such section. In addition, (a) Section 11.2 of this Agreement shall
not be amended, and no action in contravention of Section 11.2 shall be taken,
including in either case through merger or sale of assets of the Partnership or
otherwise, without the Consent of the Limited Partners and (b) this Agreement
shall not be amended, and no action shall be taken, including in either case
through merger or sale of assets of the Partnership or otherwise, which would
adversely affect the rights of the Persons set forth in Exhibit G to receive
Performance Units as described herein.

                  F. Other than incident to a transaction pursuant to Sections
11.2.B or 11.2.C, the General Partner shall not undertake to dispose of any
Partnership Property specified in the agreements listed in Exhibit H in a
taxable sale or taxable exchange prior to the dates specified in such agreements
without the prior consent of each Limited Partner which contributed all or any
portion of an interest in such Property to the Partnership, as set forth in such
agreements.

                  Section 7.4. Reimbursement of the General Partner

                  A. Except as provided in this Section 7.4 and elsewhere in
this Agreement (including the provisions of Articles 5 and 6 regarding
distributions, payments and allocations to which it may be entitled), the
General Partner shall not be compensated for its services as general partner of
the Partnership.

                  B. Subject to Section 15.11, the General Partner shall be
reimbursed on a monthly basis, or such other basis as the General Partner may
determine in its sole and absolute discretion, for all expenses it incurs
relating to the ownership of interests in and operation of, or for the benefit
of, the Partnership. The Limited Partners acknowledge that the General Partner's
sole business is the ownership of interests in and operation of the Partnership
and that such expenses are incurred for the benefit of the Partnership; provided
that, the General Partner shall not be reimbursed for expenses it incurs
relating to the organization of the Partnership and the General Partner, or the
initial public offering or subsequent offerings of REIT Shares, other shares of
capital stock or Funding Debt by the General Partner, but shall be reimbursed



                                       42
<PAGE>   47

expenses it incurs with respect to any other issuance of additional
Partnership Interests pursuant to the provisions hereof. Such reimbursements
shall be in addition to any reimbursement to the General Partner as a result of
indemnification pursuant to Section 7.7.

                  C. If and to the extent any reimbursements to the General
Partner pursuant to this Section 7.4 constitute gross income of the General
Partner (as opposed to the repayment of advances made by the General Partner on
behalf of the Partnership), such amounts shall constitute guaranteed payments
within the meaning of Section 707(c) of the Code, shall be treated consistently
therewith by the Partnership and all Partners, and shall not be treated as
distributions for purposes of computing the Partners' Capital Accounts.

                  Section 7.5. Outside Activities of the General Partner

                  A. Except in connection with a transaction authorized in
Section 11.2, without the Consent of the Limited Partners, the General Partner
shall not, directly or indirectly, enter into or conduct any business, other
than in connection with the ownership, acquisition and disposition of
Partnership Interests as a General Partner and the management of the business of
the Partnership, its operation as a public reporting company with a class (or
classes) of securities registered under the Exchange Act, its operation as a
REIT and such activities as are incidental to the same. Without the Consent of
the Limited Partners, the General Partner shall not, directly or indirectly,
participate in or otherwise acquire any interest in any real or personal
property, except its General Partner Interest, its interest in any Subsidiary
Partnership(s) (held directly or indirectly through a Qualified REIT Subsidiary)
that the General Partner holds in order to maintain such Subsidiary
Partnership's status as a partnership, and such bank accounts, similar
instruments or other short-term investments as it deems necessary to carry out
its responsibilities contemplated under this Agreement and the Charter. In the
event the General Partner desires to contribute cash to any Subsidiary
Partnership to acquire or maintain an interest of 1% or less in the capital of
such partnership, the General Partner may acquire such cash from the Partnership
in exchange for a reduction in the General Partner's Units, in an amount equal
to the amount of such cash divided by the Fair Market Value of a REIT Share on
the day such cash is received by the General Partner. Notwithstanding the
foregoing, the General Partner may acquire Properties in exchange for REIT
Shares, to the extent such Properties are immediately contributed by the General
Partner to the Partnership, pursuant to the terms described in Section 4.3.E.
Any Limited Partner Interests acquired by the General Partner, whether pursuant
to exercise by a Limited Partner of its right of Redemption, or otherwise, shall
be automatically converted into a General Partner Interest comprised of an
identical number of Partnership Units with the same rights, priorities and
preferences as the class or series so acquired. If, at any time, the General
Partner acquires material assets (other than on behalf of the Partnership) the
definition of "REIT Shares Amount" shall be adjusted, as reasonably agreed to by
the General Partner and the other Limited Partners, to reflect the relative Fair
Market Value of a share of capital stock of the General Partner relative to the
Deemed Partnership Interest Value of the related Partnership Unit. The General
Partner's General Partner Interest in the Partnership, its minority interest in
any Subsidiary Partnership(s) (held directly or indirectly through a Qualified
REIT Subsidiary) that the General Partner holds in order to maintain such
Subsidiary Partnership's status as a partnership, and interests in such
short-term liquid investments, bank accounts or similar instruments as the
General Partner deems necessary to carry out its responsibilities contemplated



                                       43
<PAGE>   48

under this Agreement and the Charter are interests which the General Partner is
permitted to acquire and hold for purposes of this Section 7.5.A.

                  B. In the event the General Partner exercises its rights under
the Charter to purchase REIT Shares or Preferred Shares, then the General
Partner shall cause the Partnership to redeem from it a number of Partnership
Units of the appropriate class as determined based on, in the case of REIT
Shares, the REIT Shares Amount equal to the number of REIT Shares so purchased,
or in the case of Preferred Shares an equal number of Preferred Units which
correspond in ranking to the Preferred Shares so purchased, in each case on the
same terms that the General Partner purchased such REIT Shares or Preferred
Shares (as applicable).

                  Section 7.6. Contracts with Affiliates

                  A. Except as expressly permitted by this Agreement, the
Partnership shall not, directly or indirectly, sell, transfer or convey any
property to, or purchase any property from, or borrow funds from, or lend funds
to, any Partner or any Affiliate of the Partnership that is not also a
Subsidiary of the Partnership, except pursuant to transactions that are on terms
that are fair and reasonable and no less favorable to the Partnership than would
be obtained from an unaffiliated third party.

                  B. The General Partner, in its sole and absolute discretion
and without the approval of the Limited Partners, may propose and adopt on
behalf of the Partnership employee benefit plans funded by the Partnership for
the benefit of employees of the General Partner, the Partnership, Subsidiaries
of the Partnership or any Affiliate of any of them in respect of services
performed, directly or indirectly, for the benefit of the Partnership, the
General Partner, or any of the Partnership's Subsidiaries. The General Partner
also is expressly authorized to cause the Partnership to issue to it Partnership
Units corresponding to REIT Shares issued by the General Partner pursuant to its
Stock Incentive Plan or any similar or successor plan and to repurchase such
Partnership Units from the General Partner to the extent necessary to permit the
General Partner to repurchase such REIT Shares in accordance with such plan.

                  Section 7.7. Indemnification

                  A. The Partnership shall indemnify an Indemnitee from and
against any and all losses, claims, damages, liabilities, joint or several,
expenses (including legal fees and expenses), judgments, fines, settlements, and
other amounts arising from any and all claims, demands, actions, suits or
proceedings, civil, criminal, administrative or investigative, that relate to
the operations of the Partnership as set forth in this Agreement in which any
Indemnitee may be involved, or is threatened to be involved, as a party or
otherwise, unless it is established that: (i) the act or omission of the
Indemnitee was material to the matter giving rise to the proceeding and either
was committed in bad faith or was the result of active and deliberate
dishonesty; (ii) the Indemnitee actually received an improper personal benefit
in money, property or services; or (iii) in the case of any criminal proceeding,
the Indemnitee had reasonable cause to believe that the act or omission was
unlawful. Without limitation, the foregoing indemnity shall extend to any
liability of any Indemnitee, pursuant to a loan guaranty or otherwise, for any
indebtedness of the Partnership or any Subsidiary of the Partnership (including,
without limitation, any indebtedness which the Partnership or any Subsidiary of
the Partnership has assumed or taken 



                                       44
<PAGE>   49

subject to), and the General Partner is hereby authorized and empowered, on
behalf of the Partnership, to enter into one or more indemnity agreements
consistent with the provisions of this Section 7.7 in favor of any Indemnitee
having or potentially having liability for any such indebtedness. The
termination of any proceeding by judgment, order or settlement does not create a
presumption that the Indemnitee did not meet the requisite standard of conduct
set forth in this Section 7.7.A. The termination of any proceeding by conviction
or upon a plea of nolo contendere or its equivalent, or any entry of an order of
probation prior to judgment, creates a rebuttable presumption that the
Indemnitee acted in a manner contrary to that specified in this Section 7.7.A.
Any indemnification pursuant to this Section 7.7 shall be made only out of the
assets of the Partnership, and any insurance proceeds from the liability policy
covering the General Partner and any Indemnitee, and neither the General Partner
nor any Limited Partner shall have any obligation to contribute to the capital
of the Partnership or otherwise provide funds to enable the Partnership to fund
its obligations under this Section 7.7.

                  B. Reasonable expenses incurred by an Indemnitee who is a
party to a proceeding may be paid or reimbursed by the Partnership in advance of
the final disposition of the proceeding upon receipt by the Partnership of (i) a
written affirmation by the Indemnitee of the Indemnitee's good faith belief that
the standard of conduct necessary for indemnification by the Partnership as
authorized in Section 7.7.A has been met and (ii) a written undertaking by or on
behalf of the Indemnitee to repay the amount if it shall ultimately be
determined that the standard of conduct has not been met.

                  C. The indemnification provided by this Section 7.7 shall be
in addition to any other rights to which an Indemnitee or any other Person may
be entitled under any agreement, pursuant to any vote of the Partners, as a
matter of law or otherwise, and shall continue as to an Indemnitee who has
ceased to serve in such capacity.

                  D. The Partnership may purchase and maintain insurance, on
behalf of the Indemnitees and such other Persons as the General Partner shall
determine, against any liability that may be asserted against or expenses that
may be incurred by any such Person in connection with the Partnership's
activities, regardless of whether the Partnership would have the power to
indemnify such Person against such liability under the provisions of this
Agreement.

                  E. For purposes of this Section 7.7, the Partnership shall be
deemed to have requested an Indemnitee to serve as fiduciary of an employee
benefit plan whenever the performance by it of its duties to the Partnership
also imposes duties on, or otherwise involves services by, it to the plan or
participants or beneficiaries of the plan; excise taxes assessed on an
Indemnitee with respect to an employee benefit plan pursuant to applicable law
shall constitute fines within the meaning of Section 7.7; and actions taken or
omitted by the Indemnitee with respect to an employee benefit plan in the
performance of its duties for a purpose reasonably believed by it to be in the
interest of the participants and beneficiaries of the plan shall be deemed to be
for a purpose which is not opposed to the best interests of the Partnership.

                  F. In no event may an Indemnitee subject the Limited Partners
to personal liability by reason of the indemnification provisions set forth in
this Agreement.



                                       45
<PAGE>   50

                  G. An Indemnitee shall not be denied indemnification in whole
or in part under this Section 7.7 because the Indemnitee had an interest in the
transaction with respect to which the indemnification applies if the transaction
was otherwise permitted by the terms of this Agreement.

                  H. The provisions of this Section 7.7 are for the benefit of
the Indemnitees, their heirs, successors, assigns and administrators and shall
not be deemed to create any rights for the benefit of any other Persons. Any
amendment, modification or repeal of this Section 7.7 or any provision hereof
shall be prospective only and shall not in any way affect the limitations on the
Partnership's liability to any Indemnitee under this Section 7.7 as in effect
immediately prior to such amendment, modification or repeal with respect to
claims arising from or relating to matters occurring, in whole or in part, prior
to such amendment, modification or repeal, regardless of when such claims may
arise or be asserted.

                  I. If and to the extent any reimbursements to the General
Partner pursuant to this Section 7.7 constitute gross income of the General
Partner (as opposed to the repayment of advances made by the General Partner on
behalf of the Partnership) such amounts shall constitute guaranteed payments
within the meaning of Section 707(c) of the Code, shall be treated consistently
therewith by the Partnership and all Partners, and shall not be treated as
distributions for purposes of computing the Partners' Capital Accounts.

                  J. Any indemnification hereunder is subject to, and limited
by, the provisions of Section 17-108 of the Act.

                  K. In the event the Partnership is made a party to any
litigation or otherwise incurs any loss or expense as a result of or in
connection with any Partner's personal obligations or liabilities unrelated to
Partnership business, such Partner shall indemnify and reimburse the Partnership
for all such loss and expense incurred, including legal fees, and the
Partnership Interest of such Partner may be charged therefor. The liability of a
Partner under this Section 7.7.K shall not be limited to such Partner's
Partnership Interest, but shall be enforceable against such Partner personally.

                  Section 7.8. Liability of the General Partner

                  A. Notwithstanding anything to the contrary set forth in this
Agreement, none of the General Partner and any of its officers, directors,
agents and employees shall be liable or accountable in damages or otherwise to
the Partnership, any Partners or any Assignees, or their successors or assigns,
for losses sustained, liabilities incurred or benefits not derived as a result
of errors in judgment or mistakes of fact or law or any act or omission if the
General Partner acted in good faith.

                  B. The Limited Partners expressly acknowledge that the General
Partner is acting for the benefit of the Partnership, the Limited Partners and
the General Partner's stockholders collectively, that the General Partner is
under no obligation to give priority to the separate interests of the Limited
Partners or the General Partner's stockholders (including, without limitation,
the tax consequences to Limited Partners or Assignees or to stockholders) in
deciding whether to cause the Partnership to take (or decline to take) any
actions and that the 



                                       46
<PAGE>   51

General Partner shall not be liable to the Partnership or to any Limited Partner
for monetary damages for losses sustained, liabilities incurred, or benefits not
derived by Limited Partners in connection with such decisions; provided, that
the General Partner has acted in good faith.

                  C. Subject to its obligations and duties as General Partner
set forth in Section 7.1.A, the General Partner may exercise any of the powers
granted to it by this Agreement and perform any of the duties imposed upon it
hereunder either directly or by or through its agents. The General Partner shall
not be responsible for any misconduct or negligence on the part of any such
agent appointed by it in good faith. In no event shall the liability of the
General Partner and its officers, directors, agents and employees, to the
Partnership and the Limited Partners under this Section 7.8 be greater than the
Partnership Interest of the General Partner.

                  D. Any amendment, modification or repeal of this Section 7.8
or any provision hereof shall be prospective only and shall not in any way
affect the limitations on the liability of the General Partner and any of its
officers, directors, agents and employees to the Partnership and the Limited
Partners under this Section 7.8 as in effect immediately prior to such
amendment, modification or repeal with respect to claims arising from or
relating to matters occurring, in whole or in part, prior to such amendment,
modification or repeal, regardless of when such claims may arise or be asserted.

                  Section 7.9. Other Matters Concerning the General Partner

                  A. The General Partner may rely and shall be protected in
acting or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, bond, debenture,
or other paper or document believed by it to be genuine and to have been signed
or presented by the proper party or parties.

                  B. The General Partner may consult with legal counsel,
accountants, appraisers, management consultants, investment bankers and other
consultants and advisers selected by it, and any act taken or omitted to be
taken in reliance upon the opinion of such Persons as to matters which such
General Partner reasonably believes to be within such Person's professional or
expert competence shall be conclusively presumed to have been done or omitted in
good faith and in accordance with such opinion.

                  C. The General Partner shall have the right, in respect of any
of its powers or obligations hereunder, to act through any of its duly
authorized officers and a duly appointed attorney or attorneys-in-fact. Each
such attorney shall, to the extent provided by the General Partner in the power
of attorney, have full power and authority to do and perform all and every act
and duty which is permitted or required to be done by the General Partner
hereunder.

                  D. Notwithstanding any other provisions of this Agreement or
any non-mandatory provision of the Act, any action of the General Partner on
behalf of the Partnership or any decision of the General Partner to refrain from
acting on behalf of the Partnership, undertaken in the good faith belief that
such action or omission is necessary or advisable in order to protect the
ability of the General Partner, for so long as the General Partner has
determined to qualify as a REIT, to (i) continue to qualify as a REIT or (ii)
except with respect to the distribution of Available Cash to the Series B
Limited Partners in accordance with Section 17.3 



                                       47
<PAGE>   52

avoid the General Partner incurring any taxes under Section 857 or Section 4981
of the Code, is expressly authorized under this Agreement and is deemed approved
by all of the Limited Partners.

                  E. So long as the Company holds any interest in the
Partnership (as either a General Partner or Limited Partner), the Company shall
have "management rights" (as such term is defined in the Plan Asset Regulation)
with respect to the Partnership and its Properties to the extent necessary to
qualify the Company as a "venture capital operating company" (as such term is
defined in the Plan Asset Regulation).

                  Section 7.10. Title to Partnership Assets

                  Title to Partnership assets, whether real, personal or mixed
and whether tangible or intangible, shall be deemed to be owned by the
Partnership as an entity, and no Partners, individually or collectively, shall
have any ownership interest in such Partnership assets or any portion thereof.
Title to any or all of the Partnership assets may be held in the name of the
Partnership, the General Partner or one or more nominees, as the General Partner
may determine, including Affiliates of the General Partner. The General Partner
hereby declares and warrants that any Partnership assets for which legal title
is held in the name of the General Partner or any nominee or Affiliate of the
General Partner shall be deemed held by the General Partner or such nominee or
Affiliate for the use and benefit of the Partnership in accordance with the
provisions of this Agreement; provided, however, that the General Partner shall
use its best efforts to cause beneficial and record title to such assets to be
vested in the Partnership as soon as reasonably practicable. All Partnership
assets shall be recorded as the property of the Partnership in its books and
records, irrespective of the name in which legal title to such Partnership
assets is held.

                  Section 7.11. Reliance by Third Parties

                  Notwithstanding anything to the contrary in this Agreement,
any Person dealing with the Partnership shall be entitled to assume that the
General Partner has full power and authority to encumber, sell or otherwise use
in any manner any and all assets of the Partnership and to enter into any
contracts on behalf of the Partnership, and such Person shall be entitled to
deal with the General Partner as if it were the Partnership's sole party in
interest, both legally and beneficially. Each Limited Partner hereby waives any
and all defenses or other remedies which may be available against such Person to
contest, negate or disaffirm any action of the General Partner in connection
with any such dealing. In no event shall any Person dealing with the General
Partner or its representatives be obligated to ascertain that the terms of this
Agreement have been complied with or to inquire into the necessity or expedience
of any act or action of the General Partner or its representatives. Each and
every certificate, document or other instrument executed on behalf of the
Partnership by the General Partner or its representatives shall be conclusive
evidence in favor of any and every Person relying thereon or claiming thereunder
that (i) at the time of the execution and delivery of such certificate, document
or instrument, this Agreement was in full force and effect, (ii) the Person
executing and delivering such certificate, document or instrument was duly
authorized and empowered to do so for and on behalf of the Partnership and (iii)
such certificate, document or instrument was duly executed and delivered in
accordance with the terms and provisions of this Agreement and is binding upon
the Partnership.

                   RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS

                  Section 8.1. Limitation of Liability

                  The Limited Partners shall have no liability under this

their Affiliates, in their capacity as such) shall take part in the operations,
management or control (within the meaning of the Act) of the Partnership's

director, employee, general partner, agent or trustee of the General Partner,
the Partnership or any of their Affiliates, in their capacity as such, shall not

                  Subject to any agreements entered into by a Limited Partner or

interests and engage in business activities in addition to those relating to the

Agreement in any business ventures of any Limited Partner or Assignee. Subject
to such agreements, none of the Limited Partners nor any other Person shall have
any rights by virtue of this Agreement or the partnership relationship
established hereby in any business ventures of any other Person, other than the
Limited Partners benefiting from the business conducted by the General Partner,
and such other Person shall have no obligation pursuant to this Agreement to
offer any interest in any such business ventures to the Partnership, any Limited
Partner or any such other Person, even if such opportunity is of a character
which, if presented to the Partnership, any Limited Partner or such other
Person, could be taken by such other Person.

his or her Capital Contribution, except to the extent of distributions made

Partnership

by the Act, and except as limited by Section 8.5.C, each Limited Partner shall

                           to the Exchange Act, and each communication sent to

                  (ii)     to obtain a copy of the Partnership's Federal, state
                           and local income tax returns for each Partnership
                           Year;

                  (iii)    to obtain a current list of the name and last known
                           business, residence or mailing address of each
                           Partner;

                           amendments thereto have been executed; and

                  (v)      to obtain true and full information regarding the
                           amount of cash and a description and statement of any
                           other property or services contributed by each
                           Partner and which each Partner has agreed to
                           contribute in the future, and the date on which each
                           became a Partner.

writing of any adjustment made in the calculation of the REIT Shares Amount
within ten (10) Business Days of the date such change becomes effective.

                  C. Notwithstanding any other provision of this Section 8.5,
the General Partner may keep confidential from the Limited Partners, for such
period of time as the General Partner determines in its sole and absolute
discretion to be reasonable, any information that (i) the General Partner
believes to be in the nature of trade secrets or other information the
disclosure of which the General Partner in good faith believes is not in the
best interests of the Partnership or (ii) the Partnership or the General Partner
is required by law or by agreements with unaffiliated third parties to keep
confidential.

                  Section 8.6. Common Limited Partner Redemption Rights

                  A. On or after the date one year after the Effective Date, or
on or after such later date as expressly provided in an agreement entered into
between the Partnership and any Common Limited Partner, each Common Limited
Partner shall have the right (subject to the terms and conditions set forth
herein and in any other such agreement, as applicable) to require the
Partnership to redeem all or a portion of the Common Partnership Units held by
such Common Limited Partner (such Partnership Units being hereafter referred to
as "Tendered Units") in exchange for the Cash Amount (a "Redemption"); provided,
that the terms of such Common Partnership Units do not provide that such Common
Partnership Units are not entitled to a right of Redemption. Unless otherwise
expressly provided in this Agreement or a separate agreement entered into
between the Partnership and the holders of such Partnership Units, all Common
Partnership Units shall be entitled to a right of Redemption hereunder.
Notwithstanding the foregoing, a PLP shall not have the right to require the
Partnership to redeem, and the Partnership may not redeem, (i) a number of
Performance Units held by such PLP in excess of the Performance Amount; or (ii)
any Performance Units prior to the second anniversary of their issuance. Any
Redemption shall be exercised pursuant to a Notice of Redemption delivered to
the General Partner by the Common Limited Partner who is exercising the right
(the "Tendering Partner"). The Cash Amount shall be delivered as a certified
check payable to the Tendering Partner within ten (10) days of the Specified
Redemption Date in accordance with the instructions set forth in the Notice of
Redemption.

                  B. Notwithstanding Section 8.6.A above, if a Common Limited
Partner has delivered to the General Partner a Notice of Redemption then the
General Partner may, in its sole and absolute discretion, (subject to the
limitations on ownership and transfer of REIT Shares set forth in Article IV.E
of the Charter) elect to acquire some or all of the Tendered Units from the
Tendering Partner in exchange for the REIT Shares Amount (as of the Specified
Redemption Date) and, if the General Partner so elects, the Tendering Partner
shall sell the Tendered Units to the General Partner in exchange for the REIT
Shares Amount. In such event, the Tendering Partner shall have no right to cause
the Partnership to redeem such Tendered Units. The General Partner shall
promptly give such Tendering Partner written notice of its election, and the
Tendering Partner may elect to withdraw its redemption request at any time prior
to the acceptance of the Cash Amount or REIT Shares Amount by such Tendering
Partner.

                  C. The REIT Shares Amount, if applicable, shall be delivered
as duly authorized, validly issued, fully paid and nonassessable REIT Shares
and, if applicable, free of any pledge, lien, encumbrance or restriction, other
than those provided in the Charter, the Bylaws of the General Partner, the
Securities Act, relevant state securities or blue sky laws and any applicable
registration rights agreement with respect to such REIT Shares entered into by
the Tendering Partner. The REIT Shares Amount shall be registered in the name
and otherwise delivered as set forth in the Notice of Redemption.
Notwithstanding any delay in such delivery (but subject to Section 8.6.E below),
the Tendering Partner shall be deemed the owner of such REIT Shares for all
purposes, including without limitation, rights to vote or consent, and receive
dividends, as of the Specified Redemption Date.



                                       51
<PAGE>   56

                  D. Each Common Limited Partner covenants and agrees with the
General Partner that all Tendered Units shall be delivered to the General
Partner free and clear of all liens, claims and encumbrances whatsoever and
should any such liens, claims and/or encumbrances exist or arise with respect to
such Tendered Units, the General Partner shall be under no obligation to acquire
the same. Each Common Limited Partner further agrees that, in the event any
state or local property transfer tax is payable as a result of the transfer of
its Tendered Units to the General Partner (or its designee), such Common Limited
Partner shall assume and pay such transfer tax.

                  E. Notwithstanding the provisions of Sections 8.6.A, 8.6.B,
8.6.C or any other provision of this Agreement, a Common Limited Partner (i)
shall not be entitled to effect a Redemption for cash or an exchange for REIT
Shares to the extent the ownership or right to acquire REIT Shares pursuant to
such exchange by such Partner on the Specified Redemption Date would cause such
Partner or any other Person, or, in the opinion of counsel selected by the
General Partner, may cause such Partner or any other Person, to violate the
restrictions on ownership and transfer of REIT Shares set forth in Article IV.E
of the Charter and (ii) shall have no rights under this Agreement to acquire
REIT Shares which would otherwise be prohibited under the Charter. To the extent
any attempted Redemption or exchange for REIT Shares would be in violation of
this Section 8.6.E, it shall be null and void ab initio and such Common Limited
Partner shall not acquire any rights or economic interest in the cash otherwise
payable upon such redemption or the REIT Shares otherwise issuable upon such
exchange.

                  F. Notwithstanding anything herein to the contrary (but
subject to Section 8.6.E above), with respect to any Redemption or exchange for
REIT Shares pursuant to this Section 8.6:

                  (i)      All Common Partnership Units acquired by the General
                           Partner pursuant thereto shall automatically, and
                           without further action required, be converted into
                           and deemed to be General Partner Interests comprised
                           of the same number and class of Common Partnership
                           Units.

                  (ii)     Without the consent of the General Partner, each
                           Common Limited Partner may not effect a Redemption
                           for less than 10,000 Partnership Units or, if the
                           Common Limited Partner holds less than 10,000
                           Partnership Units, all of the Common Partnership
                           Units held by such Common Limited Partner.

                  (iii)    Without the consent of the General Partner, each
                           Common Limited Partner may not effect a Redemption
                           during the period after the Partnership Record Date
                           with respect to a distribution and before the record
                           date established by the General Partner for a
                           distribution to its common stockholders of some or
                           all of its portion of such distribution.

                  (iv)     The consummation of any Redemption or exchange for
                           REIT Shares shall be subject to the expiration or
                           termination of the applicable waiting period, if any,
                           under the Hart-Scott-Rodino Antitrust Improvements
                           Act of 1976, as amended.

<PAGE>   57

                  (v)      Each Tendering Partner shall continue to own all
                           Common Partnership Units subject to any Redemption or
                           exchange for REIT Shares, and be treated as a Common
                           Limited Partner with respect to such Common
                           Partnership Units for all purposes of this Agreement,
                           until such Common Partnership Units are transferred
                           to the General Partner and paid for or exchanged as
                           of the Specified Redemption Date. Until a Specified
                           Redemption Date, the Tendering Partner shall have no
                           rights as a stockholder of the General Partner with
                           respect to such Tendering Partner's Common
                           Partnership Units.

                  G. In the event that the Partnership issues additional
Partnership Interests to any Additional Limited Partner pursuant to Section
4.3.C, the General Partner shall make such revisions to this Section 8.6 as it
determines are necessary to reflect the issuance of such additional Partnership
Interests.

principal office of the Partnership appropriate books and records with respect

business may be kept on, or be in the form of, punch cards, magnetic tape,
photographs, micrographics or any other information storage device; provided,
that the records so maintained are convertible into clearly legible written form

accordance with generally accepted accounting principles.

                  Section 9.2. Fiscal Year

                  Notwithstanding the provisions of Sections 9.1 and 9.3, the
General Partner may keep confidential from the Limited Partners any information

information the disclosure of which the General Partner in good faith believes
is not in the best interests of the Partnership or which the Partnership is
required by law or by agreements with unaffiliated third parties to keep
confidential.

                                   ARTICLE 10.

purposes and shall use all reasonable efforts to furnish, within ninety (90)
days of the close of each taxable year, the tax information reasonably required
by Limited Partners for Federal and state income tax reporting purposes. Each
Limited Partner shall promptly provide the General Partner with such information
relating to any Contributed Property contributed by such Limited Partner to the
Partnership.

                  Section 10.2. Tax Elections

                  Except as otherwise provided herein, the General Partner

such election (including without limitation, any election under Section 754 of
the Code) upon the General Partner's determination in its sole and absolute
discretion that such revocation is the best interests of the Partners.

                           respect to any administrative or judicial proceedings
                           for the adjustment of Partnership items required to
                           be taken into account by a Partner for income tax
                           purposes (such administrative proceedings being
                           referred to as a "tax audit" and such judicial
                           proceedings being referred to as "judicial review"),
                           and in the settlement agreement the tax matters
                           partner may expressly state that such agreement shall
                           bind all Partners, except that such settlement
                           agreement shall not bind any Partner (a) who (within
                           the time prescribed pursuant to the Code and
                           Regulations) files a statement with the IRS providing
                           that the tax matters partner shall not have the
                           authority to enter into a settlement agreement on
                           behalf of such Partner or (b) who is a "notice
                           partner" (as defined in Section 6231 of the Code) or
                           a member of a "notice group" (as defined in Section
                           6223(b)(2) of the Code);

                  (ii)     in the event that a notice of a final administrative
                           adjustment at the Partnership level of any item
                           required to be taken into account by a Partner for
                           tax purposes (a "final adjustment") is mailed to the

                           final adjustment, including the filing of a petition
                           for readjustment with the Tax Court or the United
                           States Claims Court, or the filing of a complaint for
                           refund with the District Court of the United States
                           for the district in which the Partnership's principal
                           place of business is located;

                  (iii)    to intervene in any action brought by any other
                           Partner for judicial review of a final adjustment;

                  (iv)     to file a request for an administrative adjustment
                           with the IRS at any time and, if any part of such
                           request is not allowed by the IRS, to file an
                           appropriate pleading (petition or complaint) for
                           judicial review with respect to such request;

                           period for assessing any tax which is attributable to
                           any item required to be taken into account by a
                           Partner for tax purposes, or an item affected by such
                           item; and

                  (vi)     to take any other action on behalf of the Partners of
                           the Partnership in connection with any tax audit or
                           judicial review proceeding to the extent permitted by
                           applicable law or regulations.

                  The taking of any action and the incurring of any expense by
the tax matters partner in connection with any such proceeding, except to the
extent required by law, is a matter in the sole and absolute discretion of the
tax matters partner and the provisions relating to indemnification of the
General Partner set forth in Section 7.7 shall be fully applicable to the tax
matters partner in its capacity as such.

                  C. The tax matters partner shall receive no compensation for
its services. All third party costs and expenses incurred by the tax matters
partner in performing its duties as such (including legal and accounting fees)
shall be borne by the Partnership. Nothing herein shall be construed to restrict
the Partnership from engaging an accounting firm to assist the tax matters
partner in discharging its duties hereunder, so long as the compensation paid by
the Partnership for such services is reasonable.

                  Section 10.4. Organizational Expenses

                  The Partnership shall elect to deduct expenses, if any,
incurred by it in organizing the Partnership ratably over a sixty (60) month
period as provided in Section 709 of the Code.

                  Section 10.5. Withholding

                  Each Limited Partner hereby authorizes the Partnership to
withhold from or pay on behalf of or with respect to such Limited Partner any
amount of Federal, state, local, or foreign taxes that the General Partner
determines that the Partnership is required to withhold or pay with respect to
any amount distributable or allocable to such Limited Partner pursuant to this
Agreement, including, without limitation, any taxes required to be withheld or
paid by the Partnership pursuant to Sections 1441, 1442, 1445 or 1446 of the
Code. Any amount paid on behalf of or with respect to a Limited Partner shall
constitute a loan by the Partnership to such Limited Partner, which loan shall
be repaid by such Limited Partner within fifteen (15) days after notice from the
General Partner that such payment must be made unless (i) the Partnership
withholds such payment from a distribution which would otherwise be made to the
Limited Partner or (ii) the General Partner determines, in its sole and absolute
discretion, that such payment may be satisfied out of the available funds of the
Partnership which would, but for such payment, be distributed to the Limited
Partner. Any amounts withheld pursuant to the foregoing clauses (i) or (ii)
shall be treated as having been distributed to such Limited Partner. Each
Limited Partner hereby unconditionally and irrevocably grants to the Partnership
a security interest in such Limited Partner's Partnership Interest to secure
such Limited Partner's obligation to pay to the Partnership any amounts required
to be paid pursuant to this Section 10.5. In the event that a Limited Partner
fails to pay any amounts owed to the Partnership pursuant to this Section 10.5
when due, the General Partner may, in its sole and absolute discretion, elect to
make the payment to the Partnership on behalf of such defaulting Limited
Partner, and in such event shall be deemed to have loaned such amount to such
defaulting Limited Partner and shall succeed to all rights and remedies of the
Partnership as against such defaulting Limited Partner (including, without
limitation, the right to receive distributions and the holding of a security
interest in such Limited Partner's Partnership Interest). Any amounts payable by
a Limited Partner hereunder shall bear interest at the base rate on corporate
loans at large United States money center commercial banks, as published from
time to time in the Wall Street Journal, plus two percentage points (but not
higher than the maximum lawful rate) from the date such amount is due (i.e., 15
days after demand) until such amount is paid in full. Each Limited Partner shall
take such actions as the Partnership or the General Partner shall request in
order to perfect or enforce the security interest created hereunder.

                                   ARTICLE 11.
                            TRANSFERS AND WITHDRAWALS

                  Section 11.1. Transfer

                  A. The term "transfer," when used in this Article 11 with
respect to a Partnership Interest, shall be deemed to refer to a transaction by
which the General Partner purports to assign its General Partner Interest to
another Person or by which a Limited Partner purports to assign its Limited
Partnership Interest to another Person, and includes a sale, assignment, gift
(outright or in trust), pledge, encumbrance, hypothecation, mortgage, exchange
or any other disposition by law or otherwise. Except to the extent otherwise
specified, the term "transfer" when used in this Article 11 does not include any
Redemption or exchange for REIT Shares pursuant to Section 8.6 or any exchange
for Series B Preferred Shares pursuant to Section 17.8. No part of the interest
of a Limited Partner shall be subject to the claims of any creditor, any spouse
for alimony or support, or to legal process, and may not be voluntarily or
involuntarily alienated or encumbered, except as may be specifically provided
for in this Agreement.

                  B. No Partnership Interest shall be transferred, in whole or
in part, except in accordance with the terms and conditions set forth in this
Article 11. Any transfer or purported transfer of a Partnership Interest not
made in accordance with this Article 11 shall be null and void ab initio unless
otherwise consented by the General Partner in its sole and absolute discretion.

                  Section 11.2. Transfer of General Partner's Partnership
Interest

                  A. The General Partner shall not withdraw from the Partnership
and shall not transfer all or any portion of its interest in the Partnership
(whether by sale, statutory merger, consolidation, liquidation or otherwise)
without the Consent of the Limited Partners which may be given or withheld by
each such Limited Partner in its sole and absolute discretion, and only upon the
admission of a successor General Partner pursuant to Section 12.1; provided,
however, that, subject to Sections 11.2.B, 11.2.C, 11.2.D and 11.2.E, the
General Partner may withdraw from the Partnership and transfer all of its
interest upon the merger, consolidation or sale of substantially all of the
assets of the General Partner without the consent of any Limited Partners. Upon
any transfer of a Partnership Interest in accordance with the provisions of this
Section 11.2, the transferee shall become a substitute General Partner for all
purposes herein, and shall be vested with the powers and rights of the
transferor General Partner, and shall be liable for all obligations and
responsible for all duties of the General Partner, once such transferee has
executed such instruments as may be necessary to effectuate such admission and
to confirm the agreement of such transferee to be bound by all the terms and
provisions of this Agreement with respect to the Partnership Interest so
acquired. It is a condition to any transfer otherwise permitted hereunder that
the transferee assumes, by operation of law or express agreement, all of the
obligations of the transferor General Partner under this Agreement with respect
to such transferred Partnership Interest, and no such transfer (other than
pursuant to a statutory merger or consolidation wherein all obligations and
liabilities of the transferor General Partner are assumed by a successor
corporation by operation of law) shall relieve the transferor General Partner of
its 



                                       57
<PAGE>   62

obligations under this Agreement without the Consent of the Partners, in their
reasonable discretion. In the event the General Partner withdraws from the
Partnership, or otherwise dissolves or terminates, or upon the Incapacity of the
General Partner, all of the remaining Partners may elect to continue the
Partnership business by selecting a substitute General Partner in accordance
with the Act.

                  B. Neither the General Partner nor the Partnership may engage
in any merger, consolidation or other combination with or into another person,
or effect any reclassification, recapitalization or change of its outstanding
equity interests, and the General Partner may not sell all or substantially all
of its assets (each a "Termination Transaction") unless in connection with the
Termination Transaction all holders of Partnership Units either will receive, or
will have the right to elect to receive, for each Partnership Unit an amount of
cash, securities or other property equal to the product of the REIT Share Amount
and the greatest amount of cash, securities or other property paid to the holder
of one REIT Share in consideration of one REIT Share pursuant to the Termination
Transaction. If, in connection with the Termination Transaction, a purchase,
tender or exchange offer shall have been made to and accepted by the holders of
the outstanding REIT Shares, each holder of Partnership Units will receive, or
will have the right to elect to receive, the greatest amount of cash, securities
or other property which such holder would have received had it exercised its
rights to Redemption (as set forth in Section 8.6) and received REIT Shares in
exchange for its Partnership Units immediately prior to the expiration of such
purchase, tender or exchange offer and had thereupon accepted such purchase,
tender or exchange offer. The PLPs shall have the benefit of the foregoing
provisions with respect to all of their Performance Units, notwithstanding the
limitation set forth in Section 8.6.A on a PLPs ability to exercise its rights
to a Redemption.

                  C. A Termination Transaction may also occur if the following
conditions are met: (i) substantially all of the assets directly or indirectly
owned by the surviving entity are held directly or indirectly by the Partnership
or another limited partnership or limited liability company which is the
survivor of a merger, consolidation or combination of assets with the
Partnership (in each case, the "Surviving Partnership"); (ii) the holders of
Partnership Units, including the holders of Performance Units issued or to be
issued, own a percentage interest of the Surviving Partnership based on the
relative fair market value of the net assets of the Partnership and the other
net assets of the Surviving Partnership immediately prior to the consummation of
such transaction; (iii) the rights, preferences and privileges of such holders
in the Surviving Partnership, including the holders of Performance Units issued
or to be issued, are at least as favorable as those in effect immediately prior
to the consummation of such transaction and as those applicable to any other
limited partners or non-managing members of the Surviving Partnership (except,
as to Performance Units, for such differences with Partnership Units regarding
liquidation, Redemption and exchange as are set forth herein); and (iv) such
rights of the Limited Partners, including the holders of Performance Units
issued or to be issued, include at least one of the following: (a) the right to
redeem their interests in the Surviving Partnership for the consideration
available to such persons pursuant to Section 11.2.B; or (b) the right to redeem
their Partnership Units for cash on terms equivalent to those in effect with
respect to their Partnership Units immediately prior to the consummation of such
transaction, or, if the ultimate controlling person of the Surviving Partnership
has publicly traded common equity securities, 



                                       58
<PAGE>   63

such common equity securities, with an exchange ratio based on the determination
of relative fair market value of such securities and the REIT Shares.

                  D. In connection with any transaction permitted by Section
11.2.B or 11.2.C the determination of relative fair market values and rights,
preferences and privileges of the Limited Partners shall be reasonably
determined by the General Partner's Board of Directors as of the time of the
Termination Transaction and, to the extent applicable, the values shall be no
less favorable to the holders of Partnership Units than the relative values
reflected in the terms of the Termination Transaction.

                  E. In the event of a Termination Transaction, the arrangements
with respect to Performance Units and Performance Shares will be equitably
adjusted to reflect the terms of the transaction, including, to the extent that
the REIT Shares are exchanged for consideration other than publicly traded
common equity, the transfer or release of remaining Performance Shares pursuant
to the Escrow Agreements, and resulting issuance of any Performance Units as set
forth in Section 4.3.F.

                  Section 11.3. Limited Partners' Rights to Transfer

                  A. Any Limited Partner may, at any time without the consent of
the General Partner, (i) transfer all or any portion of its Partnership Interest
to the General Partner, (ii) transfer all or any portion of its Partnership
Interest to an Affiliate controlled thereby or to an Immediate Family member,
subject to the provisions of Section 11.6, (iii) transfer all or any portion of
its Partnership Interest to a trust for the benefit of a charitable beneficiary
or to a charitable foundation, subject to the provisions of Section 11.6 and
(iv) subject to the provisions of Section 11.6, (a) pledge (a "Pledge") all or
any portion of its Partnership Interest to a lending institution, which is not
an Affiliate of such Limited Partner, as collateral or security for a bona fide
loan or other extension of credit, or (b) transfer such pledged Partnership
Interest to such lending institution in connection with the exercise of remedies
under such loan or extension of credit. In addition, each Limited Partner or
Assignee (resulting from a transfer made pursuant to clauses (i)-(iv) of the
preceding sentence) shall have the right to transfer all or any portion of its
Partnership Interest, subject to the provisions of Section 11.6 and the
satisfaction of each of the following conditions:

                  (a)      General Partner Right of First Refusal. The
                           transferring Partner shall give written notice of the
                           proposed transfer to the General Partner, which
                           notice shall state (x) the identity of the proposed
                           transferee and (y) the amount and type of
                           consideration proposed to be received for the
                           transferred Partnership Units. The General Partner
                           shall have ten (10) days upon which to give the
                           transferring Partner notice of its election to
                           acquire the Partnership Units on the proposed terms.
                           If it so elects, it shall purchase the Partnership
                           Units on such terms within ten (10) days after giving
                           notice of such election. If it does not so elect, the
                           transferring Partner may transfer such Partnership
                           Units to a third party, on economic terms no more
                           favorable to the transferee than the proposed terms,
                           subject to the other conditions of this Section 11.3.



                                       59
<PAGE>   64

                  (b)      Qualified Transferee. Any transfer of a Partnership
                           Interest shall be made only to Qualified Transferees.

                  It is a condition to any transfer otherwise permitted
hereunder that the transferee assumes by operation of law or express agreement
all of the obligations of the transferor Limited Partner under this Agreement
with respect to such transferred Partnership Interest and no such transfer
(other than pursuant to a statutory merger or consolidation wherein all
obligations and liabilities of the transferor Partner are assumed by a successor
corporation by operation of law) shall relieve the transferor Partner of its
obligations under this Agreement without the approval of the General Partner, in
its reasonable discretion. Notwithstanding the foregoing, any transferee of any
transferred Partnership Interest shall be subject to any and all ownership
limitations contained in the Charter, which may limit or restrict such
transferee's ability to exercise its Redemption rights or the exchange rights
set forth in Section 17.8 and to the representations set forth in Section 3.4.D.
Any transferee, whether or not admitted as a Substituted Limited Partner, shall
take subject to the obligations of the transferor hereunder. Unless admitted as
a Substituted Limited Partner, no transferee, whether by a voluntary transfer,
by operation of law or otherwise, shall have any rights hereunder, other than
the rights of an Assignee as provided in Section 11.5.

                  B. If a Limited Partner is subject to Incapacity, the
executor, administrator, trustee, committee, guardian, conservator, or receiver
of such Limited Partner's estate shall have all the rights of a Limited Partner,
but not more rights than those enjoyed by other Limited Partners, for the
purpose of settling or managing the estate, and such power as the Incapacitated
Limited Partner possessed to transfer all or any part of his or its interest in
the Partnership. The Incapacity of a Limited Partner, in and of itself, shall
not dissolve or terminate the Partnership.

                  C. The General Partner may prohibit any transfer otherwise
permitted under this Section 11.3 by a Limited Partner of his or her Partnership
Units if, in the opinion of legal counsel to the Partnership, such transfer
would require the filing of a registration statement under the Securities Act by
the Partnership or would otherwise violate any Federal or state securities laws
or regulations applicable to the Partnership or the Partnership Unit.

                  D. No transfer by a Limited Partner of his or her Partnership
Units (including any Redemption or exchange for REIT Shares pursuant to Section
8.6, the Redemption or exchange rights set forth in Sections 17.5 and 17.8, or
any other acquisition of Common Units or Series B Preferred Partnership Units by
the General Partner or the Partnership) may be made to any person if (i) in the
opinion of legal counsel for the Partnership, it could result in the Partnership
being treated as an association taxable as a corporation or (ii) absent the
consent of the General Partner, which may be given or withheld in its sole and
absolute discretion, such transfer could be treated as effectuated through an
"established securities market" or a "secondary market (or the substantial
equivalent thereof)" within the meaning of Section 7704 of the Code.

                  E. No transfer of any Partnership Units may be made to a
lender to the Partnership or any Person who is related (within the meaning of
Section 1.752-4(b) of the Regulations) to any lender to the Partnership whose
loan constitutes a Nonrecourse Liability, 


                                       60
<PAGE>   65


without the consent of the General Partner, in its sole and absolute discretion;
provided, that as a condition to such consent, the lender will be required to
enter into an arrangement with the Partnership and the General Partner to redeem
or exchange for the REIT Shares Amount, or the specified amount of Series B
Preferred Shares, as the case may be, any Partnership Units in which a security
interest is held simultaneously with the time at which such lender would be
deemed to be a partner in the Partnership for purposes of allocating liabilities
to such lender under Section 752 of the Code.

                  F. No Limited Partner may withdraw from the Partnership except
as a result of transfer, Redemption or exchange of Partnership Units pursuant
hereto.

                  G. No PLP (or any transferee described below) shall be
entitled to transfer any Performance Units prior to the second anniversary of
their issuance, without the consent of the General Partner, which may be given
or withheld in its sole discretion; provided, however, no such consent shall be
required under this Section 11.3.G (but subject to the other limitations of this
Article 11) for a transfer of all or a portion of such Performance Units to an
Affiliate, to Immediate Family Members, to a trust described in Section
11.3.A(iii), pursuant to a Pledge, or a transfer of such pledged units to such
lending institution in connection with the exercise of remedies under such loan
or extension of credit.

                  Section 11.4. Substituted Limited Partners

                  A. No Limited Partner shall have the right to substitute a
transferee as a Limited Partner in his or her place (including any transferee
permitted by Section 11.3 above). The General Partner shall, however, have the
right to consent to the admission of a permitted transferee of the interest of a
Limited Partner, as a Substituted Limited Partner, pursuant to this Section
11.4, which consent may be given or withheld by the General Partner in its sole
and absolute discretion. The General Partner's failure or refusal to permit a
transferee of any such interests to become a Substituted Limited Partner shall
not give rise to any cause of action against the Partnership or any Partner.

                  B. A transferee who has been admitted as a Substituted Limited
Partner in accordance with this Article 11 shall have all the rights and powers
and be subject to all the restrictions and liabilities of a Limited Partner
under this Agreement. The admission of any transferee as a Substituted Limited
Partner shall be subject to the transferee executing and delivering to the
Partnership an acceptance of all of the terms and conditions of this Agreement
(including, without limitation, the provisions of Section 2.4 and such other
documents or instruments as may be required to effect the admission, each in
form and substance satisfactory to the General Partner) and the acknowledgment
by such transferee that each of the representations and warranties set forth in
Section 3.4 are true and correct with respect to such transferee as of the date
of the transfer of the Partnership Interest to such transferee and will continue
to be true to the extent required by such representations and warranties.

                  C. Upon the admission of a Substituted Limited Partner, the
General Partner shall amend Exhibit A to reflect the name, address, number of
Partnership Units, and Percentage Interest of such Substituted Limited Partner
and to eliminate or adjust, if necessary, the name, address and interest of the
predecessor of such Substituted Limited Partner.



                                       61
<PAGE>   66

                  Section 11.5. Assignees

                  If the General Partner, in its sole and absolute discretion,
does not consent to the admission of any permitted transferee under Section 11.3
as a Substituted Limited Partner, as described in Section 11.4, such transferee
shall be considered an Assignee for purposes of this Agreement. An Assignee
shall be entitled to all the rights of an assignee of a limited partnership
interest under the Act, including the right to receive distributions from the
Partnership and the share of Net Income, Net Losses, gain and loss attributable
to the Partnership Units assigned to such transferee, the rights to transfer the
Partnership Units provided in this Article 11, the right of Redemption provided
in Section 8.6, and the right of exchange for Series B Preferred Shares set
forth in Section 17.8, but shall not be deemed to be a holder of Partnership
Units for any other purpose under this Agreement, and shall not be entitled to
effect a Consent with respect to such Partnership Units on any matter presented
to the Limited Partners for approval (such Consent remaining with the transferor
Limited Partner). In the event any such transferee desires to make a further
assignment of any such Partnership Units, such transferee shall be subject to
all the provisions of this Article 11 to the same extent and in the same manner
as any Limited Partner desiring to make an assignment of Partnership Units.
Notwithstanding anything contained in this Agreement to the contrary, as a
condition to becoming an Assignee, any prospective Assignee must first execute
and deliver to the Partnership an acknowledgment that each of the
representations and warranties set forth in Section 3.4 hereof are true and
correct with respect to such prospective Assignee as of the date of the
prospective assignment of the Partnership Interest to such prospective Assignee
and will continue to be true to the extent required by such representations or
warranties.

                  Section 11.6. General Provisions

                  A. No Limited Partner may withdraw from the Partnership other
than as a result of (i) a permitted transfer of all of such Limited Partner's
Partnership Units in accordance with this Article 11 and the transferee(s) of
such Units being admitted to the Partnership as a Substituted Limited Partner(s)
or (ii) pursuant to the exercise of its right of Redemption of all of such
Limited Partner's Partnership Units under Section 8.6 or its right of Redemption
or exchange of all of such Limited Partner's Series B Preferred Units under
Section 17.8.

                  B. Any Limited Partner who shall transfer all of such Limited
Partner's Partnership Units in a transfer permitted pursuant to this Article 11
where such transferee was admitted as a Substituted Limited Partner or pursuant
to the exercise of its rights of Redemption of all of such Limited Partner's
Partnership Units under Section 8.6 or its right of Redemption or exchange of
all of such Limited Partner's Series B Preferred Units under Section 17.8, shall
cease to be a Limited Partner.

                  C. Transfers pursuant to this Article 11 may only be made
effective on the last day of the month set forth on the written instrument of
transfer, unless the General Partner otherwise agrees.

                  D. If any Partnership Interest is transferred, assigned or
redeemed during any quarterly segment of the Partnership's fiscal year in
compliance with the provisions of this Article 11 or transferred or redeemed
pursuant to Sections 8.6 or 17.5, on any day other than the 



                                       62
<PAGE>   67

first day of a Partnership Year, then Net Income, Net Losses, each item thereof
and all other items attributable to such Partnership Interest for such fiscal
year shall be divided and allocated between the transferor Partner and the
transferee Partner by taking into account their varying interests during the
fiscal year in accordance with Section 706(d) of the Code, using the interim
closing of the books method. Except as otherwise required by Section 706(d) of
the Code or as otherwise specified in this Agreement or as otherwise determined
by the General Partner (to the extent consistent with Section 706(d) of the
Code), solely for purposes of making such allocations, each of such items for
the calendar month in which the transfer, assignment or redemption occurs shall
be allocated among all the Partners and Assignees in a manner determined by the
General Partner in its sole discretion.

                  E. In addition to any other restrictions on transfer herein
contained, including without limitation the provisions of this Article 11 and
Section 2.6, in no event may any transfer or assignment of a Partnership
Interest by any Partner (including by way of a Redemption or exchange for Series
B Preferred Shares, or any other acquisition of Common Units or Series B
Preferred Units by the Partnership or the General Partner) be made (i) to any
person or entity who lacks the legal right, power or capacity to own a
Partnership Interest; (ii) in violation of applicable law; (iii) except with the
consent of the General Partner, which may be given or withheld in its sole and
absolute discretion, of any component portion of a Partnership Interest, such as
the Capital Account, or rights to distributions, separate and apart from all
other components of a Partnership Interest; (iv) except with the consent of the
General Partner, which may be given or withheld in its sole and absolute
discretion, if in the opinion of legal counsel to the Partnership such transfer
would cause a termination of the Partnership for Federal or state income tax
purposes (except as a result of the Redemption or exchange for REIT Shares, and
a Redemption or exchange for Preferred Shares or cash pursuant to Sections 17.5
and 17.8, of all Partnership Units held by all Limited Partners or pursuant to a
Termination Transaction expressly permitted under Section 11.2); (v) if in the
opinion of counsel to the Partnership such transfer would cause the Partnership
to cease to be classified as a partnership for Federal or state income tax
purposes (except as a result of the Redemption or exchange for REIT Shares and a
Redemption or exchange for Preferred Shares pursuant to Sections 17.5 and 17.8
of all Partnership Units held by all Limited Partners); (vi) if such transfer
would cause the Partnership to become, with respect to any employee benefit plan
subject to Title I of ERISA, a "party-in-interest" (as defined in Section 3(14)
of ERISA) or a "disqualified person" (as defined in Section 4975(c) of the
Code); (vii) if such transfer would, in the opinion of counsel to the
Partnership, cause any portion of the assets of the Partnership to constitute
assets of any employee benefit plan pursuant to Department of Labor Regulations
Section 2510.2-101; (viii) if such transfer requires the registration of such
Partnership Interest or requires the registration of the exchange of such
Partnership Interests for any capital stock pursuant to any applicable Federal
or state securities laws; (ix) except with the consent of the General Partner,
which may be given or withheld in its sole and absolute discretion, if such
transfer is effectuated through an "established securities market" or a
"secondary market" (or the substantial equivalent thereof) within the meaning of
Section 7704 of the Code or such transfer causes the Partnership to become a
"Publicly Traded Partnership," as such term is defined in Sections 469(k)(2) or
7704(b) of the Code; (x) if such transfer subjects the Partnership to be
regulated under the Investment Company Act of 1940, the Investment Advisors Act
of 1940 or the Employee Retirement Income Security Act of 1974, each as amended;
(xi) if the transferee or assignee of such Partnership Interest is

unable to make the representations set forth in Section 3.4.D or such transfer
could otherwise adversely affect the ability of the General Partner to remain
qualified as a REIT; or (xii) if in the opinion of legal counsel for the
Partnership such transfer would adversely affect the ability of the General
Partner to continue to qualify as a REIT or, except with the consent of the
General Partner, which may be given or withheld in its sole and absolute
discretion, subject the General Partner to any additional taxes under Section
857 or Section 4981 of the Code.

                  F. The General Partner shall monitor the transfers of
interests in the Partnership (including any acquisition of Common Units or
Series B Preferred Partnership Units by the Partnership or the General Partner)
to determine (i) if such interests are being traded on an "established
securities market" or a "secondary market (or the substantial equivalent
thereof)" within the meaning of Section 7704 of the Code and (ii) whether such
transfers of interests would result in the Partnership being unable to qualify
for at least one of the "safe harbors" set forth in Regulations Section 1.7704-1
(or such other applicable guidance subsequently published by the IRS setting
forth safe harbors under which interests will not be treated as "readily
tradable on a secondary market (or the substantial equivalent thereof)" within
the meaning of Section 7704 of the Code) (the "Safe Harbors"). The General
Partner shall have authority (but shall not be required to) to take any steps it
determines are necessary or appropriate in its sole and absolute discretion to
prevent any trading of interests which could cause the Partnership to become a
"publicly traded partnership," or any recognition by the Partnership of such
transfers, or to insure that at least one of the Safe Harbors is met.

                              ADMISSION OF PARTNERS

                  Section 12.1. Admission of Successor General Partner

                  A successor to all of the General Partner's General Partner
Interest pursuant to Section 11.2 who is proposed to be admitted as a successor
General Partner shall be admitted to the Partnership as the General Partner,
effective upon such transfer. Any such transferee shall carry on the business of
the Partnership without dissolution. In each case, the admission shall be
subject to the successor General Partner executing and delivering to the
Partnership an acceptance of all of the terms and conditions of this Agreement
and such other documents or instruments as may be required to effect the
admission. In the case of such admission on any day other than the first day of
a Partnership Year, all items attributable to the General Partner Interest for
such Partnership Year shall be allocated between the transferring General
Partner and such successor as provided in Article 11.

                  Section 12.2. Admission of Additional Limited Partners

                  A. A Person who makes a Capital Contribution to the
Partnership in accordance with this Agreement shall be admitted to the
Partnership as an Additional Limited Partner only upon furnishing to the General
Partner (i) evidence of acceptance in form satisfactory to the General Partner
of all of the terms and conditions of this Agreement, including, without
limitation, the power of attorney granted in Section 2.4 and (ii) such other
documents or instruments as may be required in the discretion of the General
Partner in order to effect such Person's admission as an Additional Limited
Partner.

<PAGE>   69

                  B. Notwithstanding anything to the contrary in this Section
12.2, no Person shall be admitted as an Additional Limited Partner without the
consent of the General Partner, which consent may be given or withheld in the
General Partner's sole and absolute discretion. The admission of any Person as
an Additional Limited Partner shall become effective on the date upon which the
name of such Person is recorded on the books and records of the Partnership,
following the receipt of the Capital Contribution in respect of such Limited
Partner, the documents set forth in this Section 12.2.A and the consent of the
General Partner to such admission. If any Additional Limited Partner is admitted
to the Partnership on any day other than the first day of a Partnership Year,
then Net Income, Net Losses, each item thereof and all other items allocable
among Partners and Assignees for such Partnership Year shall be allocated among
such Limited Partner and all other Partners and Assignees by taking into account
their varying interests during the Partnership Year in accordance with Section
706(d) of the Code, using the interim closing of the books method. Solely for
purposes of making such allocations, each of such items for the calendar month
in which an admission of an Additional Limited Partner occurs shall be allocated
among all the Partners and Assignees, including such Additional Limited Partner,
in a manner determined by the General Partner in its sole discretion.

                  Section 12.3. Amendment of Agreement and Certificate of
Limited Partnership

                  For the admission to the Partnership of any Partner, the
General Partner shall take all steps necessary and appropriate under the Act to
amend the records of the Partnership and, if necessary, to prepare as soon as
practical an amendment of this Agreement (including an amendment of Exhibit A)
and, if required by law, shall prepare and file an amendment to the Certificate
and may for this purpose exercise the power of attorney granted pursuant to
Section 2.4.

                           DISSOLUTION AND LIQUIDATION

                  Section 13.1. Dissolution

                  The Partnership shall not be dissolved by the admission of
Substituted Limited Partners or Additional Limited Partners or by the admission
of a successor General Partner in accordance with the terms of this Agreement.
Upon the withdrawal of the General Partner, any successor General Partner
(selected as described in Section 13.1.B below) shall continue the business of
the Partnership. The Partnership shall dissolve, and its affairs shall be wound
up, upon the first to occur of any of the following ("Liquidating Events"):

                  A. the expiration of its term as provided in Section 2.5;

                  B. an event of withdrawal of the General Partner, as defined
in the Act, unless, within ninety (90) days after the withdrawal, all of the
remaining Partners agree in writing, in their sole and absolute discretion, to
continue the business of the Partnership and to the appointment, effective as of
the date of withdrawal, of a substitute General Partner;



                                       65
<PAGE>   70

                  C. prior to December 31, 2096, an election to dissolve the
Partnership made by the General Partner with the consent of Limited Partners who
hold ninety percent (90%) of the outstanding Units held by Limited Partners;

                  D. subject to the provisions of Section 7.3.C, an election to
dissolve the Partnership made by the General Partner in its sole and absolute
discretion;

                  E. entry of a decree of judicial dissolution of the
Partnership pursuant to the provisions of the Act;

                  F. the sale or disposition of all or substantially all of the
assets and properties of the Partnership;

                  G. a final and non-appealable judgment is entered by a court
of competent jurisdiction ruling that the General Partner is bankrupt or
insolvent, or a final and non-appealable order for relief is entered by a court
with appropriate jurisdiction against the General Partner, in each case under
any Federal or state bankruptcy or insolvency laws as now or hereafter in
effect, unless prior to or at the time of the entry of such order or judgment a
Majority in Interest of the remaining Limited Partners Consent in writing to
continue the business of the Partnership and to the appointment, effective as of
a date prior to the date of such order or judgment, of a substitute General
Partner; or

                  H. the Redemption or exchange for REIT Shares or Series B
Preferred Shares of all Partnership Units (other than those of the General
Partner) pursuant to this Agreement.

                  Section 13.2. Winding Up

                  A. Upon the occurrence of a Liquidating Event, the Partnership
shall continue solely for the purposes of winding up its affairs in an orderly
manner, liquidating its assets, and satisfying the claims of its creditors and
Partners. No Partner shall take any action that is inconsistent with, or not
necessary to or appropriate for, the winding up of the Partnership's business
and affairs. The General Partner (or, in the event there is no remaining General
Partner, any Person elected by a Majority in Interest of the Limited Partners
(the "Liquidator")) shall be responsible for overseeing the winding up and
dissolution of the Partnership and shall take full account of the Partnership's
liabilities and assets and the Partnership property shall be liquidated as
promptly as is consistent with obtaining the fair value thereof, and the
proceeds therefrom (which may, to the extent determined by the General Partner,
include shares of stock of the General Partner) shall be applied and distributed
in the following order:

                  (i)      First, to the payment and discharge of all of the
                           Partnership's debts and liabilities to creditors
                           other than the Partners;

                  (ii)     Second, to the payment and discharge of all of the
                           Partnership's debts and liabilities to the General
                           Partner;

                  (iii)    Third, to the payment and discharge of all of the
                           Partnership's debts and liabilities to the other
                           Partners; and



                                       66
<PAGE>   71

                  (iv)     The balance, if any, to the Partners in accordance
                           with their Capital Account balances determined after
                           giving effect to all contributions and distributions
                           for all periods, and after taking into account all
                           Capital Account adjustments for the Partnership
                           taxable year during which the liquidation occurs
                           (other than those made as a result of the liquidating
                           distribution set forth in this Section 13.2.A(iv)).

The General Partner shall not receive any additional compensation for any
services performed pursuant to this Article 13 other than reimbursement of its
expenses as provided in Section 7.4.

                  B. Notwithstanding the provisions of Section 13.2.A which
require liquidation of the assets of the Partnership, but subject to the order
of priorities set forth therein, if prior to or upon dissolution of the
Partnership the Liquidator determines that an immediate sale of part or all of
the Partnership's assets would be impractical or would cause undue loss to the
Partners, the Liquidator may, in its sole and absolute discretion, defer for a
reasonable time the liquidation of any assets except those necessary to satisfy
liabilities of the Partnership (including to those Partners as creditors) and/or
distribute to the Partners, in lieu of cash, as tenants in common and in
accordance with the provisions of Section 13.2.A, undivided interests in such
Partnership assets as the Liquidator deems not suitable for liquidation. Any
such distributions in kind shall be made only if, in the good faith judgment of
the Liquidator, such distributions in kind are in the best interest of the
Partners, and shall be subject to such conditions relating to the disposition
and management of such properties as the Liquidator deems reasonable and
equitable and to any agreements governing the operation of such properties at
such time. The Liquidator shall determine the fair market value of any property
distributed in kind using such reasonable method of valuation as it may adopt.

                  C. The Partnership shall be terminated when any notes received
in connection with any such sale or disposition referenced in Section 13.1.E
above, or in connection with the liquidation of the Partnership have been paid
and all of the cash or property available for application and distribution under
this Agreement have been applied and distributed in accordance with this
Agreement.

                  Section 13.3. Compliance with Timing Requirements of
Regulations

                  In the event the Partnership is "liquidated" within the
meaning of Regulations Section 1.704-1(b)(2)(ii)(g), distributions shall be made
pursuant to this Article 13 to the General Partner and Limited Partners who have
positive Capital Accounts in compliance with Regulations Section
1.704-1(b)(2)(ii)(b)(2). If any Partner has a deficit balance in his or her
Capital Account (after giving effect to all contributions, distributions and
allocations for the taxable years, including the year during which such
liquidation occurs), such Partner shall have no obligation to make any
contribution to the capital of the Partnership with respect to such deficit, and
such deficit shall not be considered a debt owed to the Partnership or to any
other Person for any purpose whatsoever, except to the extent otherwise agreed
to by such Partner and the General Partner. In the discretion of the Liquidator
or the General Partner, a pro rata portion of the distributions that would
otherwise be made to the General Partner and Limited Partners pursuant to this
Article 13 may be:



                                       67
<PAGE>   72

                  A. distributed to a trust established for the benefit of the
General Partner and Limited Partners for the purposes of liquidating Partnership
assets, collecting amounts owed to the Partnership, and paying any contingent or
unforeseen liabilities or obligations of the Partnership or of the General
Partner arising out of or in connection with the Partnership. The assets of any
such trust shall be distributed to the General Partner and Limited Partners from
time to time, in the reasonable discretion of the Liquidator or the General
Partner, in the same proportions and the amount distributed to such trust by the
Partnership would otherwise have been distributed to the General Partner and
Limited Partners pursuant to this Agreement; or

                  B. withheld to establish any reserves deemed necessary or
appropriate for any contingent or unforeseen liabilities or obligations of the
Partnership; and to reflect the unrealized portion of any installment
obligations owed to the Partnership; provided that, such withheld amounts shall
be distributed to the General Partner and Limited Partners as soon as
practicable.

                  Section 13.4. Deemed Distribution and Recontribution

                  Notwithstanding any other provision of this Article 13, in the
event the Partnership is liquidated within the meaning of Regulations Section
1.704-1(b)(2)(ii)(g) but no Liquidating Event has occurred, the Partnership's
property shall not be liquidated, the Partnership's liabilities shall not be
paid or discharged, and the Partnership's affairs shall not be wound up.
Instead, the Partnership shall be deemed to have distributed the Partnership
property in kind to the General Partner and Limited Partners, who shall be
deemed to have assumed and taken such property subject to all Partnership
liabilities, all in accordance with their respective Capital Accounts.
Immediately thereafter, the General Partner and Limited Partners shall be deemed
to have recontributed the Partnership property in kind to the Partnership, which
shall be deemed to have assumed and taken such property subject to all such
liabilities.

                  Section 13.5. Rights of Limited Partners

                  Except as otherwise provided in this Agreement, each Limited
Partner shall look solely to the assets of the Partnership for the return of his
Capital Contribution and shall have no right or power to demand or receive
property from the General Partner. Except as expressly set forth herein with
respect to the rights, priorities and preferences of the Preferred Limited
Partners holding any series of Preferred Units, no Limited Partner shall have
priority over any other Limited Partner as to the return of his Capital
Contributions, distributions or allocations.

                  Section 13.6. Notice of Dissolution

                  In the event a Liquidating Event occurs or an event occurs
that would, but for provisions of Section 13.1, result in a dissolution of the
Partnership, the General Partner shall, within thirty (30) days thereafter,
provide written notice thereof to each of the Partners and to all other parties
with whom the Partnership regularly conducts business (as determined in the
discretion of the General Partner) and shall publish notice thereof in a
newspaper of general circulation in each place in which the Partnership
regularly conducts business (as determined in the discretion of the General
Partner).

                  Section 13.7. Cancellation of Certificate of Limited
Partnership

                  Upon the completion of the liquidation of the Partnership cash
and property as provided in Section 13.2, the Partnership shall be terminated
and the Certificate and all qualifications of the Partnership as a foreign
limited partnership in jurisdictions other than the State of Delaware shall be
canceled and such other actions as may be necessary to terminate the Partnership
shall be taken.

                  Section 13.8. Reasonable Time for Winding-Up

                  A reasonable time shall be allowed for the orderly winding-up
of the business and affairs of the Partnership and the liquidation of its assets
pursuant to Section 13.2, in order to minimize any losses otherwise attendant
upon such winding-up, and the provisions of this Agreement shall remain in
effect between the Partners during the period of liquidation.

                  Section 13.9. Waiver of Partition

                  Each Partner hereby waives any right to partition of the
Partnership property.

                  AMENDMENT OF PARTNERSHIP AGREEMENT; CONSENTS

                  Section 14.1. Amendments

                  A. The actions requiring consent or approval of the Partners
or of the Limited Partners pursuant to this Agreement, including Section 7.3, or
otherwise pursuant to applicable law, are subject to the procedures in this
Article 14.

                  B. Amendments to this Agreement requiring the consent or
approval of Limited Partners may be proposed by the General Partner or by
Limited Partners holding twenty-five percent (25%) or more of the Partnership
Interests held by Limited Partners. Following such proposal, the General Partner
shall submit any proposed amendment to the Partners or of the Limited Partners,
as applicable. The General Partner shall seek the written consent or approval of
the Partners or of the Limited Partners on the proposed amendment or shall call
a meeting to vote thereon and to transact any other business that it may deem
appropriate. For purposes of obtaining a written consent, the General Partner
may require a response within a reasonable specified time, but not less than
fifteen (15) days, and failure to respond in such time period shall constitute a
consent which is consistent with the General Partner's recommendation (if so
recommended); provided that, an action shall become effective at such time as
requisite consents are received even if prior to such specified time.

                  Section 14.2. Action by the Partners

                  A. Meetings of the Partners may be called by the General
Partner and shall be called upon the receipt by the General Partner of a written
request by Limited Partners holding twenty-five percent (25%) or more of the
Partnership Interests held by the Limited Partners. The call shall state the
nature of the business to be transacted. Notice of any such meeting shall be



                                       69
<PAGE>   74

given to all Partners not less than seven days nor more than thirty (30) days
prior to the date of such meeting. Partners may vote in person or by proxy at
such meeting. Whenever the vote of the Percentage Interests of the Partners, or
the Consent of the Partners or Consent of the Limited Partners is permitted or
required under this Agreement, such vote or Consent may be given at a meeting of
Partners or may be given in accordance with the procedure prescribed in Section
14.1.

                  B. Any action required or permitted to be taken at a meeting
of the Partners may be taken without a meeting if a written consent setting
forth the action so taken is signed by the Percentage Interests as is expressly
required by this Agreement for the action in question. Such consent may be in
one instrument or in several instruments, and shall have the same force and
effect as a vote of the Percentage Interests of the Partners (expressly required
by this Agreement). Such consent shall be filed with the General Partner. An
action so taken shall be deemed to have been taken at a meeting held on the
effective date so certified.

                  C. Each Limited Partner may authorize any Person or Persons to
act for him by proxy on all matters in which a Limited Partner is entitled to
participate, including waiving notice of any meeting, or voting or participating
at a meeting. Every proxy must be signed by the Limited Partner or his
attorney-in-fact. No proxy shall be valid after the expiration of eleven (11)
months from the date thereof unless otherwise provided in the proxy. Every proxy
shall be revocable at the pleasure of the Limited Partner executing it.

                  D. Each meeting of Partners shall be conducted by the General
Partner or such other Person as the General Partner may appoint pursuant to such
rules for the conduct of the meeting as the General Partner or such other Person
deems appropriate.

                  E. On matters on which Limited Partners are entitled to vote,
each Limited Partner shall have a vote equal to the number of Partnership Units
held.

                  Section 15.11. Limitation to Preserve REIT Status

                  To the extent that any amount paid or credited to the General
Partner or its officers, directors, employees or agents pursuant to Section 7.4
or 7.7 would constitute gross income to the General Partner for purposes of
Sections 856(c)(2) or 856(c)(3) of the Code (a "General Partner Payment") then,
notwithstanding any other provision of this Agreement, the amount of such
General Partner Payments for any fiscal year shall not exceed the lesser of:

                           (i) an amount equal to the excess, if any, of (a)
         4.17% of the General Partner's total gross income (but not including
         the amount of any General Partner Payments) for the fiscal year which
         is described in subsections (A) through (H) of Section 856(c)(2) of the
         Code over (b) the amount of gross income (within the meaning of Section
         856(c)(2) of the Code) derived by the General Partner from sources
         other than those described in subsections (A) through (H) of Section
         856(c)(2) of the Code (but not including the amount of any General
         Partner Payments); or

                           (ii) an amount equal to the excess, if any, of (a)
         25% of the General Partner's total gross income (but not including the
         amount of any General Partner Payments) for the fiscal year which is
         described in subsections (A) through (I) of Section 856(c)(3) of the
         Code over (b) the amount of gross income (within the meaning of Section
         856(c)(3) of the Code) derived by the General Partner from sources
         other than those described in subsections (A) through (I) of Section
         856(c)(3) of the Code (but not including the amount of any General
         Partner Payments);

provided, however, that General Partner Payments in excess of the amounts set
forth in subparagraphs (i) and (ii) above may be made if the General Partner, as
a condition precedent, obtains an opinion of tax counsel that the receipt of
such excess amounts would not adversely affect the General Partner's ability to
qualify as a REIT. To the extent General Partner Payments may not be made in a
year due to the foregoing limitations, such General Partner Payments shall carry
over and be treated as arising in the following year; provided, however, that
such amounts shall not carry over for more than five years, and if not paid
within such five year period, shall expire; provided, further, that (a) as
General Partner Payments are made, such payments shall be applied first to carry
over amounts outstanding, if any and (b) with respect to carry over amounts for
more than one Partnership Year, such payments shall be applied to the earliest
Partnership Year first.

                  Section 15.12. Entire Agreement

                  This Agreement (together with the agreements listed on Exhibit
I hereto as to rights and obligations in respect of the Units held by the
Limited Partners who are parties thereto, or their permitted transferees)
contains the entire understanding and agreement among the Partners with respect
to the subject matter hereof and supersedes any other prior written or oral
understandings or agreements among them with respect thereto.

                  Section 15.13. No Rights as Stockholders



                                       72
<PAGE>   77

                  Nothing contained in this Agreement shall be construed as
conferring upon the holders of Partnership Units any rights whatsoever as
stockholders of the General Partner, including without limitation any right to
receive dividends or other distributions made to stockholders of the General
Partner or to vote or to consent or to receive notice as stockholders in respect
of any meeting of stockholders for the election of directors of the General
Partner or any other matter.

                                   ARTICLE 16.
                            SERIES A PREFERRED UNITS

                  Section 16.1. Designation and Number

                  A series of Partnership Units in the Partnership designated as
the 8 1/2% Series A Cumulative Redeemable Preferred Units (the "Series A
Preferred Units") is hereby established. The number of Series A Preferred Units
shall be 4,600,000.

                  Section 16.2 Ranking

                  The Series A Preferred Units shall, with respect to
distribution rights and rights upon voluntary or involuntary liquidation,
winding up or dissolution of the Partnership, rank (i) senior to the Common
Units and to all Partnership Units the terms of which provide that such
Partnership Units shall rank junior to the Series A Preferred Units; (ii) on a
parity with the Series B Preferred Units and all other Parity Preferred Units;
and (iii) junior to all Partnership Units which rank senior to the Series A
Preferred Units.

                  Section 16.3. Distributions

                  A. Payment of Distributions. Subject to the rights of holders
of Parity Preferred Units (including Series B Preferred Units) as to the payment
of distributions, pursuant to Section 5.1 and Section 17.3.A hereof, the General
Partner, as holder of the Series A Preferred Units, will be entitled to receive,
when, as and if declared by the Partnership acting through the General Partner,
out of Available Cash, cumulative preferential cash distributions in an amount
equal to the Series A Priority Return. Such distributions will be payable (A)
quarterly in arrears, on the 15th day of January, April, July and October of
each year and (B) in the event of a redemption of Series A Preferred Units, on
the redemption date (each a "Series A Preferred Unit Distribution Payment
Date"), commencing on the first of such payment dates to occur following their
original date of issuance. If any date on which distributions are to be made on
the Series A Preferred Units is not a Business Day, then payment of the
distribution to be made on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other payment in respect of
any such delay) except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding Business
Day, in each case with the same force and effect as if made on such date.

                  B. No Distributions in Contravention of Agreements. No
distribution on the Series A Preferred Units shall be authorized by the General
Partner or made or set apart for payment by the Partnership at such time as the
terms and provisions of any agreement of the Partnership or the General Partner,
including any agreement relating to indebtedness, prohibits such declaration,
payment or setting apart for payment or provides that such declaration, 



                                       73
<PAGE>   78

payment or setting apart for payment would constitute a breach thereof, or a
default thereunder, or if such declaration or payment shall be restricted or
prohibited by law.

                  C. Priority as to Distributions. (i) Except to the extent set
forth in Section 16.3.C(ii), so long as any Series A Preferred Units are
outstanding, no distribution of cash or other property shall be authorized,
declared, paid or set apart for payment on or with respect to any class or
series of Partnership Interest represented by Junior Units, nor shall any Junior
Units or Parity Preferred Units (including the Series B Preferred Units) be
redeemed, purchased or otherwise acquired for any consideration (or any monies
be paid to or made available for a sinking fund for the redemption of any such
Junior Units or Parity Preferred Units) by the Partnership (except by conversion
into or exchange for other Junior Units or Parity Preferred Units) unless, in
each case, full cumulative distributions have been or contemporaneously are
authorized and paid or authorized and a sum sufficient for the payment thereof
set apart for such payment on the Series A Preferred Units for all past
distribution periods and the current distribution period. The foregoing sentence
will not prohibit (a) distributions payable solely in Junior Units, (b) the
exchange of Junior Units or Parity Preferred Units (including the Series B
Preferred Units) into Partnership Interests of the Partnership ranking junior to
the Series A Preferred Units as to distributions, or (c) the redemption of
Partnership Interests corresponding to Series A Preferred Shares, Parity
Preferred Stock (including Series B Preferred Shares) with respect to
distributions or Junior Stock to be purchased by the General Partner pursuant to
the Charter to preserve the General Partner's status as a real estate investment
trust, provided that such redemption shall be upon the same terms as the
corresponding stock purchase pursuant to the Charter.

                  (ii) So long as distributions have not been paid in full (or a
sum sufficient for such full payment is not so set apart) upon the Series A
Preferred Units and any other Parity Preferred Units (including the Series B
Preferred Units), all distributions authorized and declared on the Series A
Preferred Units and all classes or series of outstanding Parity Preferred Units
(including the Series B Preferred Units) shall be authorized and declared pro
rata so that the amount of distributions authorized and declared per Series A
Preferred Unit and such other classes or series of Parity Preferred Units shall
in all cases bear to each other the same ratio that accrued distributions per
Series A Preferred Unit and such other classes or series of Parity Preferred
Units (which shall not include any accumulation in respect of unpaid
distributions for prior distribution periods if such class or series of Parity
Preferred Units do not have cumulative distribution rights) bear to each other.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distributions or payments on Series A Preferred Units which may be in
arrears.

                  D. No Further Rights. The General Partner, as holder of the
Series A Preferred Units, shall not be entitled to any distributions, whether
payable in cash, other property or otherwise, in excess of the full cumulative
distributions described herein. Any distribution payment made on the Series A
Preferred Units shall first be credited against the earliest accrued but unpaid
distribution due with respect to such Series A Preferred Units which remain
payable.

                  Section 16.4. Liquidation Proceeds

                  A. Upon voluntary or involuntary liquidation, dissolution or
winding-up of the Partnership, distributions on the Series A Preferred Units
shall be made in accordance with Article 13 of this Agreement.

                  B. Notice. Written notice of any such voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership, stating the payment
date or dates when, and the place or places where, the amounts distributable in
such circumstances shall be payable, shall be given by the General Partner
pursuant to Section 13.6 hereof.

                  C. No Further Rights. After payment of the full amount of the
liquidating distributions to which they are entitled, the General Partner, as
holder of the Series A Preferred Units, will have no right or claim to any of
the remaining assets of the Partnership.

                  D. Consolidation, Merger or Certain Other Transactions. None
of a consolidation or merger of the Partnership with or into another entity, a
merger of another entity with or into the Partnership, or a sale, lease,
transfer or conveyance of all or substantially all of the Partnership's property
or business shall be considered a liquidation, dissolution or winding up of the
Partnership.

                  Section 16.5. Redemption

                  A. Redemption. The Series A Preferred Units may not be
redeemed prior to July 27, 2003. If, on or after such date, the General Partner
elects to redeem any of the Series A Preferred Shares, the Partnership shall, on
the date set for redemption of such Series A Preferred Shares, redeem the number
of Series A Preferred Units equal to the number of Series A Preferred Shares for
which the General Partner has given notice of redemption pursuant to Section 5
of Article Third of the Series A Articles Supplementary, at a redemption price,
payable in cash, equal to the product of (i) the number of Series A Preferred
Units being redeemed, and (ii) the sum of $25 and the Preferred Distribution
Shortfall per Series A Preferred Unit, if any.

                  B. Limitation on Redemption. The Redemption Price of the
Series A Preferred Units (other than the portion thereof consisting of
accumulated but unpaid distributions) is payable solely out of the sale proceeds
of capital stock of the General Partner, which will be contributed by the
General Partner to the Partnership as an additional capital contribution, or out
of the sale of limited partner interests in the Partnership and from no other
source. For purposes of the preceding sentence, "capital stock" means any equity
securities (including Common Stock and Preferred Stock (as such terms are
defined in the Charter)), depository shares, interests, participation or other
ownership interests (however designated) and any rights (other than debt
securities convertible into or exchangeable for equity securities) or options to
purchase any of the foregoing.

                  C. Payment of Accumulated Distributions. Immediately prior to
any redemption of Series A Preferred Units, the Partnership shall pay, in cash,
any accumulated and unpaid distributions on the Series A Preferred Units to be
redeemed through the redemption date. Except as provided above, the Partnership
will make no payment or allowance for unpaid 



                                       75
<PAGE>   80

distributions, whether or not in arrears, on Series A Preferred Units for which
a notice of redemption has been given.

                  D. Procedures for Redemption. The following provisions set
forth the procedures for Redemption:

                  (i) Notice of redemption will be given by the General Partner
to the Partnership concurrently with the notice of the General Partner sent to
the holders of its Series A Preferred Shares in connection with such redemption.
Such notice shall state: (A) the redemption date; (B) the redemption price; (C)
the number of Series A Preferred Units to be redeemed; (D) the place or places
where the Series A Preferred Units are to be surrendered for payment of the
redemption price; and (E) that distributions on the Series A Preferred Units to
be redeemed will cease to accumulate on such redemption date. If less than all
of the Series A Preferred Units are to be redeemed, the notice shall also
specify the number of Series A Preferred Units to be redeemed.

                  (ii) On or after the redemption date, the General Partner
shall present and surrender the certificates, if any, representing the Series A
Preferred Units to the Partnership at the place designated in the notice of
redemption and thereupon the redemption price of such Units (including all
accumulated and unpaid distributions up to the redemption date) shall be paid to
the General Partner and each surrendered Unit certificate, if any, shall be
canceled. If fewer than all the Units represented by any such certificate
representing Series A Preferred Units are to be redeemed, a new certificate
shall be issued representing the unredeemed shares.

                  (iii) From and after the redemption date (unless the
Partnership defaults in payment of the redemption price), all distributions on
the Series A Preferred Units designated for redemption in such notice shall
cease to accumulate and all rights of the General Partner, except the right to
receive the redemption price thereof (including all accumulated and unpaid
distributions up to the redemption date), shall cease and terminate, and such
Units shall not be deemed to be outstanding for any purpose whatsoever. At its
election, the Partnership, prior to a redemption date, may irrevocably deposit
the redemption price (including accumulated and unpaid distributions to the
redemption date) of the Series A Preferred Units so called for redemption in
trust for the General Partner with a bank or trust company, in which case the
redemption notice to General Partner shall (A) state the date of such deposit,
(B) specify the office of such bank or trust company as the place of payment of
the redemption price and (C) require the General Partner to surrender the
certificates, if any, representing such Series A Preferred Units at such place
on or about the date fixed in such redemption notice (which may not be later
than the redemption date) against payment of the redemption price (including all
accumulated and unpaid distributions to the redemption date). Any monies so
deposited which remain unclaimed by the General Partner at the end of two years
after the redemption date shall be returned by such bank or trust company to the
Partnership.

                  E. No Further Rights. Any Series A Preferred Units that shall
at any time have been redeemed shall, after such redemption, have the status of
authorized but unissued Preferred Units, without designation as to series until
such shares are once more designated as part of a particular series by the
General Partner.

                  Section 16.6. Voting Rights

                  The General Partner shall not have any voting or consent
rights in respect of its partnership interest represented by the Series A
Preferred Units.

                  Section 16.7. Transfer Restrictions

                  The Series A Preferred Units shall not be transferable.

                  Section 16.8. No Conversion Rights

                  The Series A Preferred Units shall not be convertible into any
other class or series of interest in the Partnership.

                  Section 16.9. No Sinking Fund

                  No sinking fund shall be established for the retirement or
redemption of Series A Preferred Units.


                                   ARTICLE 17.
                            SERIES B PREFERRED UNITS

                  Section 17.1. Designation and Number

                  A series of Partnership Units in the Partnership designated as
the 8 5/8 Series B Cumulative Redeemable Preferred Units (the "Series B
Preferred Units") is hereby established. The number of Series B Preferred Units
shall be 1,300,000.


                  Section 17.2. Ranking

                  The Series B Preferred Units shall, with respect to
distribution rights and rights upon voluntary or involuntary liquidation,
winding up or dissolution of the Partnership, rank (i) senior to the Common
Units and to all Partnership Units the terms of which provide that such
Partnership Units shall rank junior to the Series B Preferred Units; (ii) on a
parity with the Series A Preferred Units and all other Parity Preferred Units;
and (iii) junior to all Partnership Units which rank senior to the Series B
Preferred Units.

                  Section 17.3. Distributions

                  A. Payment of Distributions. Subject to the rights of holders
of Parity Preferred Units (including the Series A Preferred Units) as to the
payment of distributions, pursuant to Section 5.1 and Section 16.3.A hereof,
holders of Series B Preferred Units will be entitled to receive, when, as and if
declared by the Partnership acting through the General Partner, out of Available
Cash, cumulative preferential cash distributions in an amount equal to the
Series B Priority Return. Such distributions will be payable (A) quarterly in
arrears, on the 15th day of January, April, July and October of each year and
(B) in the event of (i) an exchange 



                                       77
<PAGE>   82

of Series B Preferred Units into Series B Preferred Shares, or (ii) a redemption
of Series B Preferred Units, on the exchange date or redemption date, as
applicable (each a "Series B Preferred Unit Distribution Payment Date"),
commencing on the first of such payment dates to occur following their original
date of issuance. If any date on which distributions are to be made on the
Series B Preferred Units is not a Business Day, then payment of the distribution
to be made on such date will be made on the next succeeding day that is a
Business Day (and without any interest or other payment in respect of any such
delay) except that, if such Business Day is in the next succeeding calendar
year, such payment shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on such date. Distributions
on the Series B Preferred Units will be made to the holders of record of the
Series B Preferred Units on the relevant record dates, which will be fifteen
(15) days prior to the relevant Preferred Unit Distribution Payment Date (the
"Series B Preferred Unit Partnership Record Date").

                  B. Distributions Cumulative. Notwithstanding the foregoing,
distributions on the Series B Preferred Units will accrue whether or not the
terms and provisions of any agreement of the Partnership at any time prohibit
the current payment of distributions, whether or not the Partnership has
earnings, whether or not there are funds legally available for the payment of
such of such distributions and whether or not such distributions are authorized.
Accrued but unpaid distributions on the Series B Preferred Units will accumulate
as of the Preferred Unit Distribution Payment Date on which they first become
payable.

                  C. Priority as to Distributions. (i) So long as any Series B
Preferred Units are outstanding, no distribution of cash or other property shall
be authorized, declared, paid or set apart for payment on or with respect to any
class or series of Partnership Interest represented by Junior Units, nor shall
any Junior Units or Parity Preferred Units (including the Series A Preferred
Units) be redeemed, purchased or otherwise acquired for any consideration (or
any monies be paid to or made available for a sinking fund for the redemption of
any such Junior Units or Parity Preferred Units) by the Partnership (except by
conversion into or exchange for other Junior Units or Parity Preferred Units)
unless, in each case, full cumulative distributions have been or
contemporaneously are authorized and paid or authorized and a sum sufficient for
the payment thereof set apart for such payment on the Series B Preferred Units
and all classes and series of outstanding Parity Preferred Units for all
distribution periods. The foregoing sentence will not prohibit (a) distributions
payable solely in Junior Units, (b) the exchange of Junior Units or Parity
Preferred Units (including the Series A Preferred Units) into Partnership
Interests of the Partnership ranking junior to the Series B Preferred Units as
to distributions, or (c) the redemption of Partnership Interests corresponding
to Series B Preferred Shares, Parity Preferred Stock (including Series A
Preferred Shares) with respect to distributions or Junior Stock to be purchased
by the General Partner pursuant to the Charter to preserve the General Partner's
status as a real estate investment trust, provided that such redemption shall be
upon the same terms as the corresponding stock purchase pursuant to the Charter.

                  (ii) So long as distributions have not been paid in full (or a
sum sufficient for such full payment is not so set apart) upon the Series B
Preferred Units and any other Parity Preferred Units (including the Series A
Preferred Units), all distributions authorized and declared on the Series B
Preferred Units and all classes or series of outstanding Parity Preferred Units
(including the Series A Preferred Units) shall be authorized and declared pro
rata so that the 



                                       78
<PAGE>   83

amount of distributions authorized and declared per Series B Preferred Unit and
such other classes or series of Parity Preferred Units shall in all cases bear
to each other the same ratio that accrued distributions per Series B Preferred
Unit and such other classes or series of Parity Preferred Units (which shall not
include any accumulation in respect of unpaid distributions for prior
distribution periods if such class or series of Parity Preferred Units do not
have cumulative distribution rights) bear to each other. No interest, or sum of
money in lieu of interest, shall be payable in respect of any distributions or
payments on Series B Preferred Units which may be in arrears.

                  (iii) Notwithstanding anything to the contrary set forth
herein, distributions on Partnership Interests held by either (a) the General
Partner or (b) any other holder of Partnership Interest in the Partnership, in
each case ranking junior to or on parity with the Series B Preferred Units may
be made, without preserving the priority of distributions described in Sections
17.3.C(i) and (ii), but only to the extent such distributions are required to
preserve the real estate investment trust status of the General Partner and in
the case of any holder other than the General Partner only to the extent
required by the Partnership Agreement.

                  D. No Further Rights. Holders of Series B Preferred Units
shall not be entitled to any distributions, whether payable in cash, other
property or otherwise, in excess of the full cumulative distributions described
herein.

                  Section 17.4. Liquidation Proceeds

                  A. Distributions. Upon voluntary or involuntary liquidation,
dissolution or winding-up of the Partnership, distributions on the Series B
Preferred Units shall be made in accordance with Article 13 of this Agreement.

                  B. Notice. Written notice of any such voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership, stating the payment
date or dates when, and the place or places where, the amounts distributable in
such circumstances shall be payable, shall be given by the General Partner
pursuant to Section 13.6 hereof.

                  C. No Further Rights. After payment of the full amount of the
liquidating distributions to which they are entitled, Holders of Series B
Preferred Units will have no right or claim to any of the remaining assets of
the Partnership.

                  D. Consolidation, Merger or Certain Other Transactions. None
of a consolidation or merger of the Partnership with or into another entity, a
merger of another entity with or into the Partnership, or a sale, lease,
transfer or conveyance of all or substantially all of the Partnership's property
or business shall be considered a liquidation, dissolution or winding up of the
Partnership.

                  Section 17.5. Redemption

                  A. Redemption. The Series B Preferred Units may not be
redeemed prior to November 12, 2003. On or after such date, the Partnership
shall have the right to redeem the Series B Preferred Units, in whole or in
part, at any time or from time to time, upon not less than 



                                       79
<PAGE>   84

30 nor more than 60 days' written notice, at a redemption price, payable in
cash, equal to the Capital Account balance of the holder of Series B Preferred
Units (the "Redemption Price"); provided, however, that no redemption pursuant
to this Section 17.5 will be permitted if the Redemption Price does not equal or
exceed the original Capital Contribution of such holder plus the cumulative
Priority Return to the redemption date to the extent not previously distributed.
If fewer than all of the outstanding Series B Preferred Units are to be
redeemed, the Series B Preferred Units to be redeemed shall be selected pro rata
(as nearly as practicable without creating fractional units).

                  B. Limitation on Redemption. (i) The Redemption Price of the
Series B Preferred Units (other than the portion thereof consisting of
accumulated but unpaid distributions) is payable solely out of the sale proceeds
of capital stock of the General Partner, which will be contributed by the
General Partner to the Partnership as an additional capital contribution, or out
of the sale of limited partner interests in the Partnership and from no other
source. For purposes of the preceding sentence, "capital stock" means any equity
securities (including Common Stock and Preferred Stock (as such terms are
defined in the Charter)), depository shares, interests, participation or other
ownership interests (however designated) and any rights (other than debt
securities convertible into or exchangeable for equity securities) or options to
purchase any of the foregoing.

                  (ii) The Partnership may not redeem fewer than all of the
outstanding Series B Preferred Units unless all accumulated and unpaid
distributions have been paid on all Series B Preferred Units for all quarterly
distribution periods terminating on or prior to the date of redemption.

                  C. Procedures for Redemption. (i) Notice of redemption will be
(i) faxed, and (ii) mailed by the Partnership, by certified mail, postage
prepaid, not less than 30 nor more than 60 days prior to the redemption date,
addressed to the respective holders of record of the Series B Preferred Units at
their respective addresses as they appear on the records of the Partnership. No
failure to give or defect in such notice shall affect the validity of the
proceedings for the redemption of any Series B Preferred Units except as to the
holder to whom such notice was defective or not given. In addition to any
information required by law, each such notice shall state: (a) the redemption
date, (b) the Redemption Price, (c) the aggregate number of Series B Preferred
Units to be redeemed and if fewer than all of the outstanding Series B Preferred
Units are to be redeemed, the number of Series B Preferred Units to be redeemed
held by such holder, which number shall equal such holder's pro rata share
(based on the percentage of the aggregate number of outstanding Series B
Preferred Units that the total number of Series B Preferred Units held by such
holder represents) of the aggregate number of Series B Preferred Units to be
redeemed, (d) the place or places where such Series B Preferred Units are to be
surrendered for payment of the Redemption Price, (e) that distributions on the
Series B Preferred Units to be redeemed will cease to accumulate on such
redemption date and (f) that payment of the Redemption Price will be made upon
presentation and surrender of such Series B Preferred Units.

                  (ii) If the Partnership gives a notice of redemption in
respect of Series B Preferred Units (which notice will be irrevocable) then, by
12:00 noon, New York City time, on 



                                       80
<PAGE>   85

the redemption date, the Partnership will deposit irrevocably in trust for the
benefit of the Series B Preferred Units being redeemed funds sufficient to pay
the applicable Redemption Price and will give irrevocable instructions and
authority to pay such Redemption Price to the holders of the Series B Preferred
Units upon surrender of the Series B Preferred Units by such holders at the
place designated in the notice of redemption. On and after the date of
redemption, distributions will cease to accumulate on the Series B Preferred
Units or portions thereof called for redemption, unless the Partnership defaults
in the payment thereof. If any date fixed for redemption of Series B Preferred
Units is not a Business Day, then payment of the Redemption Price payable on
such date will be made on the next succeeding day that is a Business Day (and
without any interest or other payment in respect of any such delay) except that,
if such Business Day falls in the next calendar year, such payment will be made
on the immediately preceding Business Day, in each case with the same force and
effect as if made on such date fixed for redemption. If payment of the
Redemption Price is improperly withheld or refused and not paid by the
Partnership, distributions on such Series B Preferred Units will continue to
accumulate from the original redemption date to the date of payment, in which
case the actual payment date will be considered the date fixed for redemption
for purposes of calculating the applicable Redemption Price.

                  Section 17.6. Voting Rights

                  A. General. Holders of the Series B Preferred Units will not
have any voting rights or right to consent to any matter requiring the consent
or approval of the Limited Partners, except as set forth below and in Section
7.3.E.

                  B. Certain Voting Rights. So long as any Series B Preferred
Units remains outstanding, the Partnership shall not, without the affirmative
vote of the holders of at least two-thirds of the Series B Preferred Units
outstanding at the time (i) authorize or create, or increase the authorized or
issued amount of, any class or series of Partnership Interests ranking prior to
the Series B Preferred Units with respect to payment of distributions or rights
upon liquidation, dissolution or winding-up or reclassify any Partnership
Interests of the Partnership into any such Partnership Interest, or create,
authorize or issue any obligations or security convertible into or evidencing
the right to purchase any such Partnership Interests, (ii) authorize or create,
or increase the authorized or issued amount of any Parity Preferred Units or
reclassify any Partnership Interest of the Partnership into any such Partnership
Interest or create, authorize or issue any obligations or security convertible
into or evidencing the right to purchase any such Partnership Interests but only
to the extent such Parity Preferred Units are issued to an affiliate of the
Partnership, other than the General Partner to the extent the issuance of such
interests was to allow the General Partner to issue corresponding preferred
stock to persons who are not affiliates of the Partnership or (iii) either
consolidate, merge into or with, or convey, transfer or lease its assets
substantially as an entirety to, any corporation or other entity or amend, alter
or repeal the provisions of the Partnership Agreement (including, without
limitation, this Article 17), whether by merger, consolidation or otherwise, in
each case in a manner that would materially and adversely affect the powers,
special rights, preferences, privileges or voting power of the Series B
Preferred Units or the holders thereof; provided, however, that with respect to
the occurrence of any event set forth in (iii) above, so long as (a) the
Partnership is the surviving entity and the Series B Preferred Units remain
outstanding with the terms thereof unchanged, or (b) the 



                                       81
<PAGE>   86

resulting, surviving or transferee entity is a partnership, limited liability
company or other pass-through entity organized under the laws of any state and
substitutes the Series B Preferred Units for other interests in such entity
having substantially the same terms and rights as the Series B Preferred Units,
including with respect to distributions, voting rights and rights upon
liquidation, dissolution or winding-up, then the occurrence of any such event
shall not be deemed to materially and adversely affect such rights, privileges
or voting powers of the holders of the Series B Preferred Units; and provided
further, that any increase in the amount of Partnership Interests or the
creation or issuance of any other class or series of Partnership Interests
represented by Junior Units or Parity Preferred Units are not issued to an
affiliate of the Partnership, other than the General Partner to the extent the
issuance of such interests was to allow the General Partner to issue
corresponding preferred stock to persons who are not affiliates of the
Partnership, shall not be deemed to materially and adversely affect such rights,
preferences, privileges or voting powers.

                  Section 17.7. Transfer Restrictions

                  The Series B Preferred Units shall be subject to the
provisions of Article 11 hereof; provided, however, that the Series B Preferred
Units shall not be subject to the right of first refusal of the General Partner
as described in Section 11.3 hereof. No transfer of Series B Preferred Units, or
other action by the holder or holders of such Units, is permitted, without the
consent of the General Partner which consent may be given or withheld in its
sole and absolute discretion, if such transfer or other action would result in
more than four partners holding all outstanding Series B Preferred Units within
the meaning of Treasury Regulation Section 1.7704-1(h)(3)(i); provided, however,
that the General Partner's consent may not be unreasonably withheld if (a) such
transfer or other action would not result in more than ten partners holding all
outstanding Series B Preferred Units within the meaning of Treasury Regulation
Section 1.7704-1(h)(3)(i) and (b) the General Partner is relying on a provision
other than Treasury Regulation Section 1.7704-1(h) to avoid classification of
Operating Partnership as a "publicly traded partnership" within the meaning of
Code Section 7704 (a "PTP"). In addition, no transfer may be made to any person
if such transfer would cause the exchange of the Series B Preferred Units for
Series B Preferred Shares, as provided herein, to be required to be registered
under the Securities Act of 1933, as amended, or any state securities laws. If
(i) Contributor concludes based on results or projected results that there
exists (in the reasonable judgment of Contributor) an imminent and substantial
risk that the Contributor's interest in the Partnership represents or will
represent more than 19.5% of the total profits or capital interests in the
Partnership for a taxable year, (ii) Contributor delivers to the General Partner
an opinion of independent counsel to the effect that there is a substantial risk
that Contributor's interest in the Partnership represents or will represent more
than 19.5% (the "19.5% Limit") of the total profits or capital interests in the
Partnership (determined in accordance with Regulations Section 1.731-2(e)(4)),
and (iii) the General Partner agrees with the conclusions referred to in clauses
(i) and (ii) of this sentence, such agreement not to be unreasonably withheld,
then Contributor shall, subject to the above limitations, be permitted to
transfer so much of its Series B Preferred Units as may be appropriate to
alleviate the risk of not satisfying the 19.5% Limit to the trust described in
Exhibit J, with the Contributor having the rights set forth in such Exhibit.

                  Section 17.8. Exchange Rights

                  A. Right to Exchange. (i) Series B Preferred Units will be
exchangeable in whole but not in part unless expressly otherwise provided herein
at anytime on or after November 12, 2008, at the option of 51% of the holders of
all outstanding Series B Preferred Units, for authorized but previously unissued
Series B Preferred Shares at an exchange rate of one REIT Series B Preferred
Share from the General Partner for one Series B Preferred Unit, subject to
adjustment as described below (the "Exchange Price"), provided that the Series B
Preferred Units will become exchangeable at any time, in whole but not in part
unless expressly otherwise provided herein, at the option of 51% of the holders
of all outstanding Series B Preferred Units for Series B Preferred Shares if (y)
at any time full distributions shall not have been timely made on any Series B
Preferred Unit with respect to six (6) prior quarterly distribution periods,
whether or not consecutive, provided, however, that a distribution in respect of
Series B Preferred Units shall be considered timely made if made within two (2)
Business Days after the applicable Preferred Unit Distribution Payment Date if
at the time of such late payment there shall not be any prior quarterly
distribution periods in respect of which full distributions were not timely made
or (z) upon receipt by a holder or holders of Series B Preferred Units of (A)
notice from the General Partner that the General Partner or a Subsidiary of the
General Partner has taken the position that the Partnership is, or upon the
consummation of an identified event in the immediate future will be, a PTP and
(B) an opinion rendered by independent counsel familiar with such matters
addressed to a holder or holders of Series B Preferred Units, that the
Partnership is or likely is, or upon the occurrence of a defined event in the
immediate future will be or likely will be, a PTP. In addition, the Series B
Preferred Units may be exchanged for Series B Preferred Shares, in whole but not
in part unless expressly otherwise provided herein, at the option of 51% of the
holders of all outstanding Series B Preferred Units after November 12, 2001 and
prior to November 12, 2008 if such holders of a Series B Preferred Units shall
deliver to the General Partner either (i) a private ruling letter addressed to
such holder of Series B Preferred Units or (ii) an opinion of independent
counsel reasonably acceptable to the General Partner based on the enactment of
temporary or final Treasury Regulations or the publication of a Revenue Ruling,
in either case to the effect that an exchange of the Series B Preferred Units at
such earlier time would not cause the Series B Preferred Units to be considered
"stock and securities" within the meaning of section 351(e) of the Code for
purposes of determining whether the holder of such Series B Preferred Units is
an "investment company" under section 721(b) of the Code if an exchange is
permitted at such earlier date. Furthermore, the Series B Preferred Units, if
Contributor so determines, may be exchanged in whole but not in part (regardless
of whether held by Contributor) for Series B Preferred Shares (but only if the
exchange in whole may be accomplished consistently with the ownership
limitations set forth under the Series B Articles Supplementary (as defined
herein), taking into account exceptions thereto) if (1) Contributor concludes
based on results or projected results that there exists (in the reasonable
judgment of Contributor) an imminent and substantial risk that the Contributor's
interest in the Partnership represents or will represent more than 19.5% of the
total profits or capital interests in the Partnership for a taxable year, (2)
Contributor delivers to the General Partner an opinion of independent counsel to
the effect that there is a substantial risk that its interest in the Partnership
does not or will not satisfy the 19.5% Limit and (3) the General Partner agrees
with the conclusions referred to in clauses (1) and (2) of this sentence, such
agreement not to be unreasonably withheld; provided, however, that if, as a
result 



                                       83
<PAGE>   88

of such conclusion, Contributor's interest in the Partnership is reduced
pursuant to the last sentence of Section 17.7 hereof (which procedure shall be
available to Contributor to the exclusion of the procedure under this sentence
for so long as, on a cumulative basis, sales of 10% or fewer of the Series B
Preferred Units originally acquired by Contributor would in the opinion of the
above-referenced counsel reduce the risk that Contributor's interest in the
Partnership would not satisfy the 19.5% Limit to less than a substantial risk,
and thereafter shall be a permitted alternative to the procedure pursuant to
this sentence) or the risk of Contributor not satisfying the 19.5% Limit
otherwise is reduced below a substantial risk, then an exchange in whole under
this sentence shall not be permitted unless and until a change in facts occurs
and a further determination by Contributor is made under this sentence.

                  (ii) Notwithstanding anything to the contrary set forth in
Section 17.8.A(i), if an Exchange Notice (as defined herein) has been delivered
to the General Partner, then the General Partner may, at its option, within ten
(10) Business Days after receipt of the Exchange Notice, elect to cause the
Partnership to redeem all or a portion of the outstanding Series B Preferred
Units for cash in an amount equal to the original Capital Contribution per
Series B Preferred Unit and all accrued and unpaid distributions thereon to the
date of redemption. If the General Partner elects to redeem fewer than all of
the outstanding Series B Preferred Units, the number of Series B Preferred Units
held by each holder to be redeemed shall equal such holder's pro rata share
(based on the percentage of the aggregate number of outstanding Series B
Preferred Units that the total number of Series B Preferred Units held by such
holder represents) of the aggregate number of Series B Preferred Units being
redeemed.

                  (iii) In the event an exchange of all Series B Preferred Units
pursuant to Section 17.8.A would violate the provisions on ownership limitation
of the General Partner set forth in Section 7 of the Articles Supplementary to
the Charter with respect to Series B Preferred Shares (the "Series B Articles
Supplementary"), each holder of Series B Preferred Units shall be entitled to
exchange, pursuant to the provisions of Section 17.8.B, a number of Series B
Preferred Units which would comply with the provisions on the ownership
limitation of the General Partner set forth in such Section 7 of the Series B
Articles Supplementary, with respect to such holder, and any Series B Preferred
Units not so exchanged (the "Excess Units") shall be redeemed by the Partnership
for cash in an amount equal to the original Capital Contribution per Excess
Unit, plus any accrued and unpaid distributions thereon to the date of
redemption subject to any restriction thereon contained in any debt instrument
or agreement of the Partnership. In the event an exchange would result in Excess
Units, as a condition to such exchange, each holder of such units agrees to
provide representations and covenants reasonably requested by the General
Partner relating to (i) the widely held nature of the interests in such holder,
sufficient to assure the General Partner that the holder's ownership of stock of
the General Partner (without regard to the limits described above) will not
cause any individual to own in excess of 9.0% of the stock of the General
Partner; and (ii) to the extent such holder can so represent and covenant
without obtaining information from its owners, the holder's ownership of tenants
of the Partnership and its affiliates. For purposes of determining the number of
Excess Units under this Section 17.8.A(iii), the "Beneficial Ownership Limit"
and "Constructive Ownership Limit" set forth in the Series B Articles
Supplementary shall be deemed to be 9.0%. To the extent the General Partner
would not be able to pay the cash set forth above in exchange for the Excess
Units, and to the extent consistent with the Charter, the General Partner agrees
that it will grant 



                                       84
<PAGE>   89

to the holders of the Series B Preferred Units exceptions to the Beneficial
Ownership Limit and Constructive Ownership Limit set forth in the Series B
Articles Supplementary sufficient to allow such holders to exchange all of their
Series B Preferred Units for REIT Series B Preferred Stock, provided such
holders furnish to the General Partner representations acceptable to the General
Partner in its sole and absolute discretion which assure the General Partner
that such exceptions will not jeopardize the General Partner's tax status as a
REIT for purposes of federal and applicable state law. Notwithstanding any
provision of this Agreement to the contrary, no Series B Limited Partner shall
be entitled to effect an exchange of Series B Preferred Units for Series B
Preferred Shares to the extent that ownership or right to acquire such shares
would cause the Partner or any other Person or, in the opinion of counsel
selected by the General Partner, may cause the Partner or any other Person, to
violate the restrictions on ownership and transfer of Series B Preferred Shares
set forth in the Charter. To the extent any such attempted exchange for Series B
Preferred Shares would be in violation of the previous sentence, it shall be
void ab initio and such Series B Limited Partner shall not acquire any rights or
economic interest in the Series B Preferred Shares otherwise issuable upon such
exchange.

                  (iv) The redemption of Series B Preferred Units described in
Section 17.8.A(ii) and (iii) shall be subject to the provisions of Section
17.5.B(i) and Section 17.5.C(ii); provided, however, that the term "Redemption
Price" in such Sections 17.5.B(i) and 17.5.C(ii) shall be read to mean the
original Capital Contribution per Series B Preferred Unit being redeemed as set
forth on Exhibit A plus all accrued and unpaid distributions to the redemption
date.

                  B. Procedure for Exchange and/or Redemption of Series B
Preferred Units.

                  (i) Any exchange shall be exercised pursuant to a notice of
exchange (the "Exchange Notice") delivered to the General Partner by the
Partners representing at least 51% of the outstanding Series B Preferred Units
(or by Contributor in the case of an exchange pursuant to the last sentence of
Section 17.8.A.(i) hereof) by (a) fax and (b) by certified mail postage prepaid.
The General Partner may effect any exchange of Series B Preferred Units, or
exercise its option to cause the Partnership to redeem any portion of the Series
B Preferred Units for cash pursuant to Section 17.8.A(ii) or redeem Excess Units
pursuant to Section 17.8.A(iii), by delivering to each holder of record of
Series B Preferred Units, within ten (10) Business Days following receipt of the
Exchange Notice, (a) if the General Partner elects to cause the Partnership to
acquire any of the Series B Preferred Units then outstanding, (1) certificates
representing the Series B Preferred Shares being issued in exchange for the
Series B Preferred Units of such holder being exchanged and (2) a written notice
(a "Redemption Notice") stating (A) the redemption date, which may be the date
of such Redemption Notice or any other date which is not later than sixty (60)
days following the receipt of the Exchange Notice, (B) the redemption price, (C)
the place or places where the Series B Preferred Units are to be surrendered and
(D) that distributions on the Series B Preferred Units will cease to accrue on
such redemption date, or (b) if the General Partner elects to cause the
Partnership to redeem all of the Series B Preferred Units then outstanding in
exchange for cash, a Redemption Notice. Series B Preferred Units shall be deemed
canceled (and any corresponding Partnership Interest represented thereby deemed
terminated) simultaneously with the delivery of shares of Series B Preferred
Shares (with respect to Series B Preferred Units exchanged) or simultaneously
with the redemption date (with respect to Series B Preferred Units redeemed).
Holders of Series B 



                                       85
<PAGE>   90

Preferred Units shall deliver any canceled certificates representing Series B
Preferred Units which have been exchanged or redeemed to the office of General
Partner (which currently is located at 505 Montgomery Street, San Francisco,
California 94111) within ten (10) Business Days of the exchange or redemption
with respect thereto. Notwithstanding anything to the contrary contained herein,
any and all Series B Preferred Units to be exchanged for REIT Series B Preferred
Stock pursuant to this Section 17.8 shall be so exchanged in a single
transaction at one time. As a condition to exchange, the General Partner may
require the holders of Series B Preferred Units to make such representations as
may be reasonably necessary for the General Partner to establish that the
issuance of Series B Preferred Shares pursuant to the exchange shall not be
required to be registered under the Securities Act or any state securities laws.
Any Series B Preferred Shares issued pursuant to this Section 17.8 shall be
delivered as shares which are duly authorized, validly issued, fully paid and
nonassessable, free of any pledge, lien, encumbrance or restriction other than
those provided in the Charter, the Bylaws of the General Partner, the Securities
Act and relevant state securities or blue sky laws.

                  The certificates representing the Series B Preferred Shares
issued upon exchange of the Series B Preferred Units shall contain the following
legend:

                  THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE
                  TRANSFERRED, SOLD, ASSIGNED, PLEDGED, HYPOTHECATED OR
                  OTHERWISE DISPOSED OF EXCEPT (A) PURSUANT TO AN EFFECTIVE
                  REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS
                  AMENDED (THE "ACT"), AND STATE SECURITIES LAWS OR (B) IF THE
                  CORPORATION HAS BEEN FURNISHED WITH A SATISFACTORY OPINION OF
                  COUNSEL FOR THE HOLDER OF THE SHARES REPRESENTED HEREBY, OR
                  OTHER EVIDENCE SATISFACTORY TO THE CORPORATION, THAT SUCH
                  TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER
                  DISPOSITION IS EXEMPT FROM THE PROVISIONS OF SECTION 5 OF THE
                  ACT AND STATE SECURITIES LAWS AND THE RULES AND REGULATIONS
                  THEREUNDER.

                  (ii) In the event of an exchange of Series B Preferred Units
for Series B Preferred Shares, an amount equal to the accrued and unpaid
distributions to the date of exchange on any Series B Preferred Units tendered
for exchange shall (i) accrue on the Series B Preferred Shares into which such
Series B Preferred Units are exchanged, and (ii) continue to accrue on such
Series B Preferred Units, which shall remain outstanding following such
exchange, with the General Partner as the holder of such REIT Series B Preferred
Units. Notwithstanding anything to the contrary set forth herein, in no event
shall a holder of a Series B Preferred Unit that was validly exchanged for
Series B Preferred Shares pursuant to this section (other than the General
Partner holding such Series B Preferred Unit following any such exchange),
receive a distribution out of Available Cash of the Partnership, if such holder,
after exchange, is entitled to receive a distribution out of Available Cash with
respect to the Series B Preferred Shares for which such Series B Preferred Unit
was exchanged or redeemed. Further for purposes of the 



                                       86
<PAGE>   91

foregoing, in the event of an exchange of Series B Preferred Units for Series B
Preferred Shares, if the accrued and unpaid distributions per Series B Preferred
Unit is not the same for each Series B Preferred Unit, the accrued and unpaid
distributions per Series B Preferred Unit for each such Series B Preferred Unit
shall be equal to the greatest amount of such accrued and unpaid distributions
per Series B Preferred Unit on any such unit.

                  (iii) Fractional Series B Preferred Shares are not to be
issued upon exchange but, in lieu thereof, the General Partner will pay a cash
adjustment based upon the fair market value of the Series B Preferred Shares on
the day prior to the exchange date as determined in good faith by the Board of
Directors of the General Partner.

                  C. Adjustment of Exchange Price. In case the General Partner
shall be a party to any transaction (including, without limitation, a merger,
consolidation, statutory share exchange, tender offer for all or substantially
all of the General Partner's capital stock or sale of all or substantially all
of the General Partner's assets), in each case as a result of which the Series B
Preferred Shares will be converted into the right to receive shares of capital
stock, other securities or other property (including cash or any combination
thereof), each Series B Preferred Unit will thereafter be exchangeable into the
kind and amount of shares of capital stock and other securities and property
receivable (including cash or any combination thereof) upon the consummation of
such transaction by a holder of that number of Series B Preferred Shares or
fraction thereof into which one Series B Preferred Unit was exchangeable
immediately prior to such transaction. The General Partner may not become a
party to any such transaction unless the terms thereof are consistent with the
foregoing.

                  Section 17.9. No Conversion Rights

                  The Series B Preferred Units shall not be convertible into any
other class or series of interest in the Partnership.

                  Section 17.10. No Sinking Fund

                  No sinking fund shall be established for the retirement or
redemption of Series B Preferred Units.

                        CONSTRUCTIVE OWNERSHIP DEFINITION

                  The term "Constructively Owns" means ownership determined
through the application of the constructive ownership rules of Section 318 of
the Code, as modified by Section 856(d)(5) of the Code. Generally, these rules
provide the following:

         a. an individual is considered as owning the Ownership Interest that is
owned, actually or constructively, by or for his spouse, his children, his
grandchildren, and his parents;

         b. an Ownership Interest that is owned, actually or constructively, by
or for a partnership, limited liability company or estate is considered as owned
proportionately by its partners, members or beneficiaries;

         c. an Ownership Interest that is owned, actually or constructively, by
or for a trust is considered as owned by its beneficiaries in proportion to the
actuarial interest of such beneficiaries (provided, however, that in the case of
a "grantor trust" the Ownership Interest will be considered as owned by the
grantors);

         d. if ten percent (10%) or more in value of the stock in a corporation
is owned, actually or constructively, by or for any person, such person shall be
considered as owning the Ownership Interest that is owned, actually or
constructively, by or for such corporation in that proportion which the value of
the stock which such person so owns bears to the value of all the stock in such
corporation;

         e. an Ownership Interest that is owned, actually or constructively, by
or for a partner or member which actually or constructively owns a 25% or
greater capital interest or profits interest in a partnership or limited
liability company, or by or for a beneficiary of an estate or trust, shall be
considered as owned by the partnership, limited liability company, estate, or
trust (or, in the case of a grantor trust, the grantors);

         f. if ten percent (10%) or more in value of the stock in a corporation
is owned, actually or constructively, by or for any person, such corporation
shall be considered as owning the Ownership Interest that is owned, actually or
constructively, by or for such person;

         g. if any person has an option to acquire an Ownership Interest
(including an option to acquire an option or any one of a series of such
options), such Ownership Interest shall be considered as owned by such person;

         h. an Ownership Interest that is constructively owned by a person by
reason of the application of the rules described in paragraphs (a) through (g)
above shall, for purposes of applying paragraphs (a) through (g), be considered
as actually owned by such person provided, however, that (i) an Ownership
Interest constructively owned by an individual by reason of paragraph (a) shall
not be considered as owned by him for purposes of again applying paragraph (a)
in order to make another the constructive owner of such Ownership Interest, (ii)
an Ownership Interest constructively owned by a partnership, estate, trust, or
corporation by reason of the application of paragraphs (e) or (f) shall not be
considered as owned by it for purposes of applying paragraphs (b), (c), or (d)
in order to make another the constructive owner of such Ownership Interest,
(iii) if an Ownership Interest may be considered as owned by an individual under
paragraphs (a) or (g), it shall be considered as owned by him under paragraph
(g) and (iv) for purposes of the above described rules, an S corporation shall
be treated as a partnership and any stockholder of the S corporation shall be
treated as a partner of such partnership except that this rule shall not apply
for purposes of determining whether stock in the S corporation is constructively
owned by any person.

         i. For purposes of the above summary of the constructive ownership
rules, the term "Ownership Interest" means the ownership of stock with respect
to a corporation and, with respect to any other type of entity, the ownership of
an interest in either its assets or net profits.

                                PERFORMANCE UNITS

                  Any Performance Units to be issued by the Partnership pursuant
to Section 4.3.F. shall be issued to the following Persons in the following
amounts:

                  1. The first 3,000,000 Performance Units to be issued shall be
issued 90% to the "Old PLPs" (as defined below) and 10% to the "New PLPs" (as
defined below).

                  2. Any Performance Units to be issued in excess of those set
forth in paragraph 1. above shall be issued 80% to the Old PLPs and 20% to the
New PLPs.

                  3. The Performance Units allocable to each group of PLPs
pursuant to paragraphs 1. and 2. above shall be allocated among the PLPs within
such group in accordance with each PLP's percentage interest as set forth in the
definitions below.

                  4. The receipt of Performance Units by a PLP is subject to the
following vesting requirements:

                           A. Any Person who is listed in the definition of Old
PLP or New PLP and who does not remain employed, by one or more of the
Partnership, the IMS or their affiliates, for at least one (1) year from the
closing of the initial public offering of the common stock of the General
Partner, other than Persons who cease to be so employed as a result of a
Permitted Reason, shall have their name removed from such definition and such
Person's percentage as set forth in such definition shall be transferred to the
other Persons listed in such definition in proportion to their immediately
preceding percentages.

                           B. Performance Units issued to a New PLP shall be
subject to a vesting requirement pursuant to which a
New PLP will have their ownership of Performance Units vest in 25% increments on
each anniversary of such issuance, beginning on the first such anniversary and
ending on the fourth such anniversary. In order for such portion of the
Performance Units to vest on an anniversary, the New PLP must continue to be
employed by one or more of the Partnership, the IMS or their affiliates on such
anniversary (the "Employment Requirement"). In the event a New PLP ceases to
meet the Employment Requirement, he or she shall immediately forfeit any
Performance Units which have not previously vested. Notwithstanding the
foregoing, (i) all Performance Units held by New PLPs meeting the Employment
Requirement at the effective time of a Termination Transaction shall vest at
such time; and (ii) the General Partner may, in its sole and absolute
discretion, cause the immediate vesting of some or all of the Performance Units
issued to one or more of the New PLPs.

                           C. Any Performance Units forfeited pursuant to
paragraph B. above shall be reissued by the Partnership to each of the Old PLPs
and New PLPs in proportion to the number of Performance Units originally issued
to each such PLP (including Performance Units then held by a New PLP which have
not yet vested). Any Performance Units which are reissued to a New PLP pursuant
to this paragraph 4.C. with respect to such New PLP's Performance Units which
have not yet vested (based on the percentage of such New PLP's Performance Units
that 



                                       G-1
<PAGE>   102

have not yet vested), shall be unvested Performance Units and shall vest or
be forfeited in accordance with or at the same time as the Performance Units
with respect to which such reissued Performance Units were acquired. Any other
Performance Units which are reissued to a PLP pursuant to this paragraph 4.C.
shall be fully vested upon such reissuance.

                           D. Units which have not vested may not be exchanged
or redeemed (including pursuant to Section 8.6), sold or otherwise disposed of
by a PLP.

                           E. If by January 31, 1999, 100% of the percentage
interests allocable to the New PLPs have not been allocated (i.e., a portion of
such percentage interests continues to be allocable to "TBD"), any such
unallocated percentage interests shall be reallocated on such date to the other
Persons listed in such definition in proportion to their immediately preceding
percentages.


                                   Definitions

"Old PLPs" means the Persons set forth on Schedule G-1 attached hereto, with the
percentage interest so indicated, as adjusted pursuant to paragraph 4.A. above.

                           "Purported Record Transferee" shall mean, with
                  respect to any purported Transfer (or other event) which

                  (b)(ii), the holder of the Partnership Units as set forth or

                  any Assignee of such Partnership Units, if such Transfer or
                  ownership had been valid under subsection (b)(i).

                           "Restriction Termination Date" shall mean the first
                  day after the date hereof on which the General Partner
                  determines, in its sole and absolute discretion, that
                  compliance with subsection (b)(i) is no longer necessary or
                  advisable.

                           "Transfer" shall mean any sale, transfer, gift,
                  assignment, devise or other disposition of Partnership Units,
                  (including (i) the granting of any option or entering into any
                  agreement for the sale, transfer or other disposition of
                  Partnership Units or (ii) the sale, transfer, assignment or
                  other disposition of any securities (or rights convertible
                  into or exchangeable for Partnership Units), whether voluntary
                  or involuntary, whether such transfer has occurred of record
                  or beneficially or Constructively (including but not limited
                  to transfers of interests in other entities which results in
                  changes in Constructive Ownership of Partnership Units), and
                  whether such transfer has occurred by operation of law or
                  otherwise.

                           "Trust" shall mean each of the trusts provided for in
                  subsection (c).

                           "Trustee" shall mean any Person unaffiliated with the
                  Partnership, or a Purported Beneficial Transferee, or a
                  Purported Record Transferee, that is appointed by the
                  Partnership to serve as trustee of a Trust.

Capitalized terms used and not defined herein shall have the meanings ascribed
to them in the Third Amended and Restated Agreement of Limited Partnership of
AMB Property, L.P. (the "Partnership Agreement), as such agreement may be
amended from time to time. All references to "Section" refer to the Partnership
Agreement.

         (b) Restriction on Ownership and Transfers.

                  (i) Prior to the Restriction Termination Date, no Person,
other than an Exempted Person, shall at any time Constructively Own Partnership
Units in excess of the Ownership Limit if the representations contained in
Section 3.4.D are not at such time true and correct.

                  (ii) If, prior to the Restriction Termination Date, any
Transfer or other event occurs that, if effective, would result in any Person
Constructively Owning Partnership Units in violation of subsection (b)(i), (1)
then that number of Partnership Units that otherwise would cause such Person to
violate subsection (b)(i) (rounded up to the nearest whole Partnership Unit)
shall be automatically transferred (provided such Transfer is not in violation
of the restrictions on transfer set forth in the Partnership Agreement, except
to the extent the General Partner waives such restrictions) to a Trust for the
benefit of a Charitable Beneficiary, as described in subsection (c), 



                                       J-2
<PAGE>   109

effective as of the close of business on the business day prior to the date of
such Transfer or other event, and such Purported Beneficial Transferee shall
thereafter have no rights in such Partnership Units or (2) if, for any reason,
the transfer to the Trust described in clause (1) of this sentence is not
automatically effective as provided therein to prevent any Person from
Constructively Owning Partnership Units in violation of subsection (b)(i), then
the Transfer of that number of Partnership Units that otherwise would cause any
Person to violate subsection (b)(i) shall be void ab initio, and the Purported
Beneficial Transferee shall have no rights in such Partnership Units.

         (c) Transfers of Partnership Units in Trust.

                  (i) Upon any purported Transfer or other event described in
subsection (b)(ii), such Partnership Units shall be deemed to have been
transferred to the Trustee in his capacity as trustee of a Trust for the
exclusive benefit of one or more Charitable Beneficiaries. Such transfer to the
Trustee shall be deemed to be effective as of the close of business on the
business day prior to the purported Transfer or other event that results in a
transfer to the Trust pursuant to subsection (b)(ii). The Trustee shall be
appointed by the Partnership and shall be a Person unaffiliated with the
Partnership, any Purported Beneficial Transferee, or any Purported Record
Transferee. Each Charitable Beneficiary shall be designated by the Partnership
as provided in subsection (c)(vi).

                  (ii) Partnership Units held by the Trustee shall be issued and
outstanding Partnership Units of the Partnership. The Purported Beneficial
Transferee or Purported Record Transferee shall have no rights in the
Partnership Units held by the Trustee. The Purported Beneficial Transferee or
Purported Record Transferee shall not benefit economically from ownership of any
Partnership Units held in trust by the Trustee, shall have no rights to
distributions or allocations with respect to Partnership Units held in the Trust
and shall not possess any rights to vote or other rights attributable to the
Partnership Units held in the Trust.

                  (iii) The Trustee shall have all voting rights and rights to
distributions and allocations with respect to Partnership Units held in the
Trust, which rights shall be exercised for the exclusive benefit of the
Charitable Beneficiary. Any distribution paid prior to the discovery by the
Partnership that Partnership Units have been transferred to the Trustee shall be
paid to the Trustee upon demand, and any distribution with respect to such
Partnership Units shall be paid when due to the Trustee. Any distributions so
paid over to the Trustee shall be held in trust for the Charitable Beneficiary.

                  The Purported Record Transferee and Purported Beneficial
Transferee shall have no voting rights with respect to the Partnership Units
held in the Trust and, subject to Delaware law, effective as of the date the
Partnership Units has been transferred to the Trustee, the Trustee shall have
the authority (at the Trustee's sole discretion) (i) to rescind as void any vote
cast by a Purported Record Transferee with respect to such Partnership Units
prior to the discovery by the Partnership that the Partnership Units has been
transferred to the Trustee and (ii) to recast such vote in accordance with the
desires of the Trustee acting for the benefit of the Charitable Beneficiary;
provided, however, that if the Partnership has already taken irreversible
action, then the Trustee shall not have the authority to rescind and recast such
vote. Notwithstanding any other provision of this Exhibit J to the contrary,
until the Partnership has received notification that the Partnership Units have
been transferred into a Trust, the Partnership shall be entitled to rely on its
Partnership 



                                       J-3
<PAGE>   110

Unit transfer and other unitholder records for purposes of preparing Exhibit A
to the Partnership Agreement, lists of unitholders entitled to vote at meetings,
and otherwise conducting votes of Partners.

                  (iv) Within 20 days of receiving notice from the Partnership
that Partnership Units have been transferred to the Trust, the Trustee of the
Trust shall, in accordance with the terms of (and subject to the limitations
contained in) the Partnership Agreement, sell the Partnership Units held in the
Trust to a Person, designated by the Trustee, whose ownership of the Partnership
Units will not violate the ownership limitations set forth in subsection (b)(i).
Upon such sale, the interest of the Charitable Beneficiary in the Partnership
Units sold shall terminate and the Trustee shall distribute the net proceeds of
the sale to the Purported Record Transferee and to the Charitable Beneficiary as
provided in this subsection (c)(iv). The Purported Record Transferee shall
receive the lesser of (1) the price paid by the Purported Record Transferee for
the Partnership Units in the transaction that resulted in such transfer to the
Trust (or, if the event which resulted in the transfer to the Trust did not
involve a purchase of such Partnership Units at Market Price, the Market Price
of such Partnership Units on the day of the event which resulted in the transfer
of such Partnership Units to the Trust) and (2) the price per Partnership Unit
received by the Trustee (net of any commissions and other expenses of sale) from
the sale or other disposition of the Partnership Units held in the Trust. Any
net sales proceeds in excess of the amount payable to the Purported Record
Transferee shall be immediately paid to the Charitable Beneficiary together with
any distributions thereon. If, prior to the discovery by the Partnership that
Partnership Units have been transferred to the Trustee, such Partnership Units
are sold by a Purported Record Transferee then (i) such Partnership Units shall
be deemed to have been sold on behalf of the Trust and (ii) to the extent that
the Purported Record Transferee received an amount for such Partnership Units
that exceeds the amount that such Purported Record Transferee was entitled to
receive pursuant to this subsection (c)(iv), such excess shall be paid to the
Trustee upon demand. The expenses described in item (2) above shall include any
expenses of administering the Trust, any transfer of Partnership Units thereto
or disposition of Partnership Units thereby, which shall be allocated equitably
among the Partnership Units which are transferred to the Trust.

                  (v) Partnership Units transferred to the Trustee shall be
deemed to have been offered for sale to the Partnership, or its designee, at a
price per Partnership Unit equal to the lesser of (i) the price paid by the
Purported Record Transferee for the Partnership Units in the transaction that
resulted in such transfer to the Trust (or, if the event which resulted in the
transfer to the Trust did not involve a purchase of such Partnership Units at
Market Price, the Market Price of such Partnership Units on the day of the event
which resulted in the transfer of such Partnership Units to the Trust) and (ii)
the Market Price on the date the Partnership, or its designee, accepts such
offer. The Partnership shall have the right to accept such offer until the
Trustee has sold the Partnership Units held in the Trust pursuant to subsection
(c)(iv). Upon such a sale to the Partnership, the interest of the Charitable
Beneficiary in the Partnership Units sold shall terminate and the Trustee shall
distribute the net proceeds of the sale to the Purported Record Transferee and
any distributions held by the Trustee with respect to such Partnership Units
shall thereupon be paid to the Charitable Beneficiary.

                  (vi) By written notice to the Trustee, the Partnership shall
designate one or more nonprofit organizations to be the Charitable Beneficiary
of the interest in the Trust such that the 



                                       J-4
<PAGE>   111

Partnership Units held in the Trust would not violate the restrictions set forth
in subsection (b)(i) in the hands of such Charitable Beneficiary.

         (d) Remedies For Breach. If the General Partner shall at any time
determine in good faith that a Transfer or other event has taken place in
violation of subsection (b) or that a Person intends to acquire, has attempted
to acquire or may acquire beneficial ownership (determined without reference to
any rules of attribution) or Constructive Ownership of any Partnership Units of
the Partnership in violation of subsection (b), the General Partner shall take
such action as it deems advisable to refuse to give effect or to prevent such
Transfer, including, but not limited to, causing the Partnership to redeem
Partnership Units, refusing to give effect to such Transfer on the books of the
Partnership or instituting proceedings to enjoin such Transfer; provided,
however, that any Transfers (or, in the case of events other than a Transfer,
ownership or Constructive Ownership) in violation of subsection (b)(i), shall
automatically result in the transfer to a Trust as described in subsection
(b)(ii).

         (e) Notice of Restricted Transfer. Any Person who acquires or attempts
to acquire or own Partnership Units in violation of subsection (b), or any
Person who is a Purported Beneficial Transferee such that an automatic transfer
to a Trust results under subsection (b)(ii), shall immediately give written
notice to the Partnership of such event and shall provide to the Partnership
such other information as the Partnership may request in order to determine the
effect, if any, of such Transfer or attempted Transfer on such Person's
compliance with subsection (b)(i).

         (f) Owners Required To Provide Information. Prior to the Restriction
Termination Date each Person who is a beneficial owner or Constructive Owner of
Partnership Units and each Person who is holding Partnership Units for a
beneficial owner or Constructive Owner shall provide to the Partnership such
information that the Partnership may request, in good faith, in order to
determine the Partnership's status as a partnership (as opposed to a
corporation) or the General Partner's status as a REIT for federal income tax
purposes.

         (g) Remedies Not Limited. Nothing contained in this Exhibit J shall
limit the authority of the General Partner to take such other action as it deems
necessary or advisable to protect the Partnership and the interests of its
Partners by preservation of the Partnership's status as a partnership (as
opposed to a corporation) or the General Partner's status as a REIT for federal
income tax purposes.

         (h) Ambiguity. In the case of an ambiguity in the application of any of
the provisions of this Exhibit J, including any definition contained in
subsection (a), the General Partner shall have the power to determine the
application of the provisions of this Exhibit J with respect to any situation
based on the facts known to it. In the event that a provision of this Exhibit J
requires an action by the General Partner and Exhibit J fails to provide
specific guidance with respect to such action, the General Partner shall have
the power to determine the action to be taken so long as such action is not
contrary to the provisions of Exhibit J. Absent a decision to the contrary by
the General Partner (which the General Partner may make in its sole and absolute
discretion), if a Person would have (but for the remedies set forth in
subsection (b)) acquired Constructive Ownership of Partnership Units in
violation of subsection (b)(i), such remedies (as applicable) shall apply first
to the Partnership Units which, but for such remedies, would have been actually
owned 



                                       J-5
<PAGE>   112

by such Person, and second to Partnership Units which, but for such remedies,
would have been Constructively Owned (but not actually owned) by such Person,
pro rata among the Persons who actually own such Partnership Units based upon
the relative number of the Partnership Units held by each such Person.
