statements discussed on page 7.

Unfavorable Changes in Apartment Market and Economic Conditions Could Adversely
Affect Occupancy Levels and Rental Rates

     Market and economic conditions in the various metropolitan areas of the
United States in which we operate may significantly affect our occupancy levels
and rental rates and therefore our profitability. This may impair our ability to
satisfy our financial obligations and pay distributions to our shareholders.
Factors that may adversely affect these conditions include the following:

     .    a reduction in jobs and other local economic downturns;

     .    oversupply of, or reduced demand for, apartment homes;

     .    declines in household formation; and

     .    rent control or stabilization laws, or other laws regulating rental
          housing, which could prevent us from raising rents to offset increases
          in operating costs.

     The weakness in the United States economy has been exacerbated by the
events of September 11, 2001, as well as by the United States' war on terrorism.
The weak economy has adversely affected employment and other significant
elements of the economy that drive productivity and the financial strength of
businesses. Any continuation or worsening of current economic conditions,
generally and in our principal market areas, could have a material adverse
effect on our occupancy levels, our rental rates and our ability to
strategically acquire and dispose of apartment communities. This may impair our
ability to satisfy our financial obligations and pay distributions to our
shareholders.

Acquisitions or New Development May Not Achieve Anticipated Results

     We intend to continue to selectively acquire apartment communities that
meet our investment criteria. Our acquisition activities and their success may
be exposed to the following risks:

     .    An acquired community may fail to perform as we expected in analyzing
          our investment, or a significant exposure related to the acquired
          property may go undetected during our due diligence procedures.

     .    When we acquire an apartment community, we often invest additional
          amounts in it with the intention of increasing profitability. These
          additional investments may not produce the anticipated improvements in
          profitability.

                                       2



     .    New developments may not achieve forecasted rents or occupancy levels
          or problems with construction or local building codes may delay
          initial occupancy dates for all or a portion of a development
          community.

Possible Difficulty of Selling Apartment Communities Could Limit Operational and
Financial Flexibility

     We periodically dispose of apartment communities that no longer meet our
strategic objectives. There can be no assurance that potential purchasers will
be willing to pay prices acceptable to us. A weak market may limit our ability
to change our portfolio promptly in response to changing economic conditions.
Furthermore, a significant portion of the proceeds from our overall property
sales may be held in escrow accounts in order for some sales to qualify as a
like-kind exchange under Section 1031 of the Internal Revenue Code so that any
related capital gain can be deferred for federal income tax purposes. As a
result, we may not have immediate access to all of the cash flow generated from
our property sales. In addition, federal tax laws limit our ability to profit on
the sale of communities that we have owned for fewer than four years, and this
limitation may prevent us from selling communities when market conditions are
favorable.

Increased Competition Could Limit Our Ability to Lease Apartment Homes or
Increase or Maintain Rents

     Our apartment communities compete with numerous housing alternatives in
attracting residents, including other apartment communities and single-family
rental homes, as well as owner occupied single- and multi-family homes.
Competitive housing in a particular area could adversely affect our ability to
lease apartment homes and increase or maintain rents.

Insufficient Cash Flow Could Affect Our Debt Financing and Create Refinancing
Risk

     We are subject to the risks normally associated with debt financing,
including the risk that our cash flow will be insufficient to make required
payments of principal and interest or restrict our borrowing capacity under our
line of credit due to debt covenant restraints. We cannot assure you that
sufficient cash flow will be available to make all required principal payments
and still satisfy our distribution requirements to maintain our status as a
REIT, nor can we assure you that the full limits of our line of credit will be
available to us if our operating performance falls outside the constraints of
our debt covenants. Additionally, we are likely to need to refinance
substantially all of our outstanding debt as it matures. We may not be able to
refinance existing debt, or the terms of any refinancing may not be as favorable
as the terms of the existing debt, which could create pressures to sell assets
or to issue additional equity when we would otherwise choose not to do so.

Failure to Generate Sufficient Revenue Could Impair Debt Service Payments and
Distributions to Shareholders

     If our apartment communities do not generate sufficient net rental income
to meet rental expenses, our ability to make required payments of interest and
principal on our debt securities and to pay distributions to our shareholders
will be adversely affected. The following factors, among others, may affect the
net rental income generated by our apartment communities:

     .    the national and local economies;

     .    local real estate market conditions, such as an oversupply of
          apartment homes;

                                       3



     .    tenants' perceptions of the safety, convenience and attractiveness of
          our communities and the neighborhoods where they are located;

     .    our ability to provide adequate management, maintenance and insurance;
          and

     .    rental expenses, including real estate taxes and utilities.

     Expenses associated with our investment in a community, such as debt
service, real estate taxes, insurance and maintenance costs, are generally not
reduced when circumstances cause a reduction in rental income from that
community. If a community is mortgaged to secure payment of debt and we are
unable to make the mortgage payments, we could sustain a loss as a result of
foreclosure on the community or the exercise of other remedies by the mortgagee.

Debt Level May Be Increased

     Our current debt policy does not contain any limitations on the level of
debt that we may incur, although our ability to incur debt is limited by
covenants in our bank and other credit agreements. We manage our debt to be in
compliance with these debt covenants, but subject to compliance with these
covenants, we may increase the amount of our debt at any time without a
concurrent improvement in our ability to service the additional debt.

Financing May Not Be Available and Could be Dilutive

     Our ability to execute our business strategy depends on our access to an
appropriate blend of debt financing, including unsecured lines of credit and
other forms of secured and unsecured debt, and equity financing, including
common and preferred equity. Debt or equity financing may not be available in
sufficient amounts, or on favorable terms or at all. If we issue additional
equity securities to finance developments and acquisitions instead of incurring
debt, the interests of our existing shareholders could be diluted.

Development and Construction Risks Could Impact Our Profitability

     We intend to continue to develop and construct apartment communities.
Development activities may be conducted through wholly-owned affiliated
companies or through joint ventures with unaffiliated parties. Our development
and construction activities may be exposed to the following risks:

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

     .    If we are unable to find joint venture partners to help fund the
          development of a community or otherwise obtain acceptable financing
          for the developments, our development potential may be limited.

     .    We may abandon development opportunities that we have already begun to
          explore, and we may fail to recover expenses already incurred in
          connection with exploring them.

                                       4



     .    We may be unable to complete construction and lease-up of a community
          on schedule, or incur development or construction costs that exceed
          our original estimates, and we may be unable to charge rents that
          would compensate for any increase in such costs.

     .    Occupancy rates and rents at a newly developed community may fluctuate
          depending on a number of factors, including market and economic
          conditions, preventing us from meeting our profitability goals for
          that community.

     Construction costs have been increasing in our existing markets, and the
costs of upgrading acquired communities have, in some cases, exceeded our
original estimates. We may experience similar cost increases in the future. Our
inability to charge rents that will be sufficient to offset the effects of any
increases in these costs may impair our profitability.

Failure to Succeed in New Markets May Limit Our Growth

     We may from time to time make acquisitions outside of our existing market
areas if appropriate opportunities arise. We may be exposed to a variety of
risks if we choose to enter new markets and we may not be able to operate
successfully in new markets. These risks include, among others:

     .    inability to evaluate accurately local apartment market conditions and
          local economies;

     .    inability to obtain land for development or to identify appropriate
          acquisition opportunities;

     .    inability to hire and retain key personnel; and

     .    lack of familiarity with local governmental and permitting procedures.

Changing Interest Rates Could Increase Interest Costs and Could Affect the
Market Price of Our Securities

     We currently have, and expect to incur in the future, debt bearing interest
at rates that vary with market interest rates. Therefore, if interest rates
increase, our interest costs will rise to the extent our variable rate debt is
not hedged effectively. In addition, an increase in market interest rates may
lead purchasers of our securities to demand a higher annual yield, which could
adversely affect the market price of our common and preferred stock and debt
securities.

Limited Investment Opportunities Could Adversely Affect Our Growth

     We expect that other real estate investors will compete with us to acquire
existing properties and to develop new properties. These competitors include
insurance companies, pension and investment funds, developer partnerships,
investment companies and other apartment REITs. This competition could increase
prices for properties of the type that we would likely pursue, and our
competitors may have greater resources than we do. As a result, we may not be
able to make attractive investments on favorable terms, which could adversely
affect our growth.

                                        5



Failure to Integrate Acquired Communities and New Personnel Could Create
Inefficiencies

     To grow successfully, we must be able to apply our experience in managing
our existing portfolio of apartment communities to a larger number of
properties. In addition, we must be able to integrate new management and
operations personnel as our organization grows in size and complexity. Failures
in either area will result in inefficiencies that could adversely affect our
expected return on our investments and our overall profitability.

Interest Rate Hedging Contracts May Be Ineffective and May Result in Material
Charges

     From time to time when we anticipate issuing debt securities, we may seek
to limit our exposure to fluctuations in interest rates during the period prior
to the pricing of the securities by entering into interest rate hedging
contracts. We may do this to increase the predictability of our financing costs.
Also, from time to time we may rely on interest rate hedging contracts to limit
our exposure under variable rate debt to unfavorable changes in market interest
rates. If the pricing of new debt securities is not within the parameters of, or
market interest rates produce a lower interest cost than that which we incur
under a particular interest rate hedging contract, the contract is ineffective.
Furthermore, the settlement of interest rate hedging contracts has involved and
may in the future involve material charges.

Potential Liability for Environmental Contamination Could Result in Substantial
Costs

     Under various federal, state and local environmental laws, as a current or
former owner or operator, we could be required to investigate and remediate the
effects of contamination of currently or formerly owned real estate by hazardous
or toxic substances, often regardless of our knowledge of or responsibility for
the contamination and solely by virtue of our current or former ownership or
operation of the real estate. In addition, we could be held liable to a
governmental authority or to third parties for property damage and for
investigation and clean-up costs incurred in connection with the contamination.
These costs could be substantial, and in many cases environmental laws create
liens in favor of governmental authorities to secure their payment. The presence
of such substances or a failure to properly remediate any resulting
contamination could materially and adversely affect our ability to borrow
against, sell or rent an affected property.

Compliance With REIT Share Ownership Limit May Prevent Takeovers Beneficial to
Shareholders

     One of the requirements for maintenance of our qualification as a REIT for
federal income tax purposes is that no more than 50% in value of our outstanding
capital stock may be owned by five or fewer individuals, including entities
specified in the Internal Revenue Code, during the last half of any taxable
year. Our charter includes provisions allowing us to stop transfers of and
redeem our shares that are intended to assist us in complying with this
requirement. These provisions may have the effect of delaying, deferring or
preventing someone from taking control of us, even though a change of control
might involve a premium price for our shareholders or might otherwise be in our
shareholders' best interests. See the subsection entitled "Requirements for
Qualification" in the section entitled "Federal Income Tax Consequences of Our
Status as a REIT" in this prospectus.

Failure to Qualify as a REIT Would Cause Us to Be Taxed as a Corporation, Which
Would Significantly Lower Funds Available For Distribution to Our Shareholders

     If we fail to qualify as a REIT for federal income tax purposes, we would
be taxed as a corporation. We cannot assure you that we are qualified as a REIT
or that we will remain qualified as a REIT in the future. Qualification as a
REIT involves the application of highly technical and complex

                                        6



provisions of the federal income tax laws, as to which there are only limited
judicial and administrative interpretations, and requires favorable
determination of various factual matters and circumstances not entirely within
our control. In addition, future legislation, new regulations, administrative
interpretations or court decisions may significantly change the tax laws or the
application of the tax laws with respect to our qualification as a REIT for
federal income tax purposes or the federal income tax consequences of our
qualification.

     If, in any taxable year, we fail to qualify as a REIT, we would be subject
to federal income tax on our taxable income at regular corporate rates, plus any
applicable alternative minimum tax. In addition, unless we are entitled to
relief under applicable statutory provisions, we would be disqualified from
treatment as a REIT for the four taxable years following the year in which we
lose our qualification. The additional tax liability resulting from the failure
to qualify as a REIT would significantly reduce or eliminate funds otherwise
available for distribution to our shareholders. Furthermore, we would no longer
be required to make distributions to our shareholders. See the section entitled
"Federal Income Tax Consequences of our Status as a REIT" in this prospectus.

Failure to Make Required Distributions Would Subject Us to Tax.

     In order to qualify as a REIT, each year we must pay out to our
shareholders at least 90% of our taxable income, other than any net capital
gain. To the extent that we satisfy the distribution requirement, but distribute
less than 100% of our taxable income, we will be subject to federal corporate
income tax on our undistributed taxable income. In addition, we will be subject
to a 4% nondeductible excise tax if the actual amount that we pay out to our
shareholders in a calendar year is less than a minimum amount specified under
federal tax laws. We may be required to borrow money or sell assets to make
distributions sufficient to enable us to pay out enough of our taxable income to
satisfy the distribution requirement and to avoid corporate income tax and the
4% excise tax in a particular year.

The Ability of Our Shareholders to Control Our Policies and Effect a Change of
Control of Our Company is Limited, Which May Not Be in Our Shareholders' Best
Interests

     In 1998, we adopted a shareholder rights plan. Under the terms of the
shareholder rights plan, our Board of Directors can in effect prevent a person
or group from acquiring more than 15% of the outstanding shares of our common
stock. Unless our Board of Directors approves the person's purchase, after that
person acquires more than 15% of our outstanding common stock, all other
shareholders will have the right to purchase securities from us at a price that
is less than their then fair market value. Purchases by other shareholders would
substantially reduce the value and influence of the shares of our common stock
owned by the acquiring person. Our Board of Directors, however, can prevent the
shareholder rights plan from operating in this manner. This gives our Board of
Directors significant discretion to approve or disapprove a person's efforts to
acquire a large interest in us.

                           FORWARD-LOOKING INFORMATION

     We have included in this document, and in the documents incorporated by
reference in this document, statements containing "forward-looking information,"
as defined by the Private Securities Litigation Reform Act of 1995.
Forward-looking information, by its nature, involves estimates, projections,
goals, forecasts, assumptions, risks and uncertainties that could cause actual
results or outcomes to differ materially from those expressed in a statement
that contains forward-looking information. Such forward-looking statements
include, without limitation, statements concerning property acquisitions and
dispositions, development activity and capital expenditures, capital raising
activities, rent growth, occupancy and rental expense growth. Examples of
statements containing

                                        7



forward-looking information that we make in this document include, but are not
limited to, statements regarding our expectations, beliefs, plans, goals,
objectives and future financial or other performance. Words such as "expects,"
"anticipates," "intends," "plans," "believes," "seeks," "estimates" and
variations of such words and similar expressions are intended to identify such
forward-looking statements. Any statement containing forward-looking information
speaks only as of the date on which it is made; and, except to fulfill our
obligations under the United States securities laws, we undertake no obligation
to update any such statement to reflect events or circumstances after the date

     Examples of factors that can affect our expectations, beliefs, plans,
goals, objectives and future financial or other performance include, but are not

with the SEC from time to time.

     All such factors are difficult to predict, contain uncertainties that may
materially affect actual results, and may be beyond our control. New factors
emerge from time to time, and it is not possible for our management to predict
all of such factors or to assess the effect of each such factor on our business.

     Although we believe that the assumptions underlying the forward-looking
statements contained herein are reasonable, any of the assumptions could be
inaccurate, and therefore there can be no assurance that such statements

             FEDERAL INCOME TAX CONSEQUENCES OF OUR STATUS AS A REIT

     The following is a summary of material federal income tax considerations
that may be relevant to a prospective holder of the common stock. The discussion
does not address all aspects of taxation that may be relevant to particular
shareholders in light of their personal investment or tax circumstances, or to
certain types of shareholders who are subject to special treatment under the
federal income tax laws, such as insurance companies, financial institutions or
broker-dealers, and, except as discussed below, tax-exempt organizations,
foreign corporations, and persons who are not citizens or residents of the
United States.

     The statements in this discussion are based on current provisions of the
Internal Revenue Code of 1986, as amended, existing, temporary, and final
Treasury regulations thereunder, and current administrative rulings and court
decisions. No assurance can be given that future legislative, judicial, or
administrative actions or decisions, which may be retroactive in effect, will
not affect the accuracy of any statements in this Prospectus with respect to the
transactions entered into or contemplated prior to the effective date of such
changes.

--------------------------------------------------------------------------------
                  We urge you to consult your own tax advisor regarding the
specific tax consequences to you of ownership of our common stock and of our
election to be taxed as a REIT. Specifically, you should consult your own tax
advisor regarding the federal, state, local, foreign, and other tax consequences
of such ownership and election, and regarding potential changes in applicable
tax laws.

--------------------------------------------------------------------------------

Taxation of United Dominion

     We elected to be taxed as a REIT under the federal income tax laws
commencing with our taxable year ended December 31, 1972. We believe that,
commencing with such taxable year, we have been organized and have operated in
such a manner as to qualify for taxation as a REIT under the Code, and we intend
to continue to operate in such a manner, but no assurance can be given that we
will operate in a manner so as to continue to qualify as a REIT. This section
discusses the laws governing the federal income tax treatment of a REIT and its
shareholders. These laws are highly technical and complex.

                                       10



     Our qualification and taxation as a REIT depend upon our ability to meet on
a continuing basis, through actual annual operating results, certain
qualification tests set forth in the federal tax laws. Those qualification tests
involve the percentage of income that we earn from specified sources, the
percentage of our assets that falls within specified categories, the diversity
of our share ownership, and the percentage of our earnings that we distribute.
The REIT qualification tests are described in more detail below. No assurance
can be given that the actual results of our operation for any particular taxable
year will satisfy such requirements. For a discussion of the tax consequences of
our failure to qualify as a REIT, see "--Failure to Qualify."

     If we qualify as a REIT, we generally will not be subject to federal income
tax on the taxable income that we distribute to our shareholders. The benefit of
that tax treatment is that it avoids the "double taxation," or taxation at both
the corporate and shareholder levels, that generally results from owning stock
in a corporation. However, we will be subject to federal tax in the following
circumstances:

     .     We will pay federal income tax on taxable income, including net
           capital gain, that we do not distribute to our shareholders during,
           or within a specified time period after, the calendar year in which
           the income is earned.

     .     We may be subject to the "alternative minimum tax" on any items of
           tax preference that we do not distribute or allocate to our
           shareholders.

     .     We will pay income tax at the highest corporate rate on (1) net
           income from the sale or other disposition of property acquired
           through foreclosure ("foreclosure property") that we hold primarily
           for sale to customers in the ordinary course of business and (2)
           other non-qualifying income from foreclosure property.

     .     We will pay a 100% tax on net income from sales or other dispositions
           of property, other than foreclosure property, that we hold primarily
           for sale to customers in the ordinary course of business.

     .     If we fail to satisfy the 75% gross income test or the 95% gross
           income test, as described below under "--Requirements for
           Qualification--Income Tests," and nonetheless continue to qualify as
           a REIT because we meet other requirements, we will pay a 100% tax on
           (1) the gross income attributable to the greater of the amounts by
           which we fail the 75% and 95% gross income tests, multiplied by (2) a
           fraction intended to reflect our profitability.

     .     If we fail to distribute during a calendar year at least the sum of
           (1) 85% of our REIT ordinary income for such year, (2) 95% of our
           REIT capital gain net income for such year, and (3) any undistributed
           taxable income from prior periods, we will pay a 4% excise tax on the
           excess of such required distribution over the amount we actually
           distributed.

     .     We may elect to retain and pay income tax on our net long-term
           capital gain. In that case, a U.S. shareholder would be taxed on its
           proportionate share of our undistributed long-term capital gain and
           would receive a credit or refund for its proportionate share of the
           tax we paid.

     .     If we acquire any asset from a C corporation, or a corporation that
           generally is subject to full corporate-level tax, in a merger or
           other transaction in which we acquire a basis

                                       11



           in the asset that is determined by reference to the C corporation's
           basis in the asset, we will pay tax at the highest regular corporate
           rate applicable if we recognize gain on the sale or disposition of
           such asset during the 10-year period after we acquire such asset. The
           amount of gain on which we will pay tax generally is the lesser of:

           -    the amount of gain that we recognize at the time of the sale or
                disposition; and

           -    the amount of gain that we would have recognized if we had sold
                the asset at the time we acquired the asset.

     .     We will incur a 100% excise tax on transactions with a "taxable REIT
           subsidiary" that are not conducted on an arm's-length basis.

Requirements for Qualification

     A REIT is a corporation, trust, or association that meets the following
requirements:

     .     it is managed by one or more trustees or directors;

     .     its beneficial ownership is evidenced by transferable shares, or by
           transferable certificates of beneficial interest;

     .     it would be taxable as a domestic corporation, but for the REIT
           provisions of the federal income tax laws;

     .     it is neither a financial institution nor an insurance company
           subject to special provisions of the federal income tax laws;

     .     at least 100 persons are beneficial owners of its shares or ownership
           certificates;

     .     no more than 50% in value of its outstanding shares or ownership
           certificates is owned, directly or indirectly, by five or fewer
           individuals, as defined in the federal income tax laws to include
           certain entities, during the last half of any taxable year;

     .     it elects to be a REIT, or has made such election for a previous
           taxable year, and satisfies all relevant filing and other
           administrative requirements established by the Internal Revenue
           Service that must be met to elect and maintain REIT status;

     .     it uses a calendar year for federal income tax purposes and complies
           with the recordkeeping requirements of the federal income tax laws;
           and

     .     it meets certain other qualification tests, described below,
           regarding the nature of its income and assets.

     We must meet requirements 1 through 4 during our entire taxable year and
must meet requirement 5 during at least 335 days of a taxable year of 12 months,
or during a proportionate part of a taxable year of less than 12 months. If we
comply with all the requirements for ascertaining the ownership of our
outstanding shares in a taxable year and have no reason to know that we violated
requirement 6, we will be deemed to have satisfied requirement 6 for such
taxable year. For purposes of determining share ownership under requirement 6,
an "individual" generally includes a supplemental

                                       12



unemployment compensation benefits plan, a private foundation, or a portion of a
trust permanently set aside or used exclusively for charitable purposes. An
"individual," however, generally does not include a trust that is a qualified
employee pension or profit sharing trust under the federal income tax laws, and
beneficiaries of such a trust will be treated as holding shares of our stock in
proportion to their actuarial interests in the trust for purposes of requirement
6.

     We have has issued sufficient common stock with enough diversity of
ownership to satisfy requirements 5 and 6 set forth above. In addition, our
charter restricts the ownership and transfer of the common stock so that we
should continue to satisfy requirements 5 and 6.

     A corporation that is a "qualified REIT subsidiary" is not treated as a
corporation separate from its parent REIT. All assets, liabilities, and items of
income, deduction, and credit of a "qualified REIT subsidiary" are treated as
assets, liabilities, and items of income, deduction, and credit of the REIT. A
"qualified REIT subsidiary" is a corporation, all of the capital stock of which
is owned by the REIT, other than a "taxable REIT subsidiary." Thus, in applying
the requirements described herein, any "qualified REIT subsidiary" that we own
will be ignored, and all assets, liabilities, and items of income, deduction,
and credit of such subsidiary will be treated as our assets, liabilities, and
items of income, deduction, and credit.

     In the case of a REIT that is a partner in a partnership, the REIT is
treated as owning its proportionate share of the assets of the partnership and
as earning its allocable share of the gross income of the partnership for
purposes of the applicable REIT qualification tests. Thus, our proportionate
share of the assets, liabilities, and items of income of any other partnership,
joint venture, or limited liability company that is treated as a partnership for
federal income tax purposes in which we own or will acquire an interest,
directly or indirectly, are treated as our assets and gross income for purposes
of applying the various REIT qualification requirements.

     REITs are permitted to own up to 100% of the stock of one or more "taxable
REIT subsidiaries" ("TRSs"). A TRS is a fully taxable corporation that may
provide services to our tenants without tainting our rent from the related
properties and may perform activities unrelated to our tenants, such as
third-party management, development, and other independent business activities.
TRSs are subject to corporate income tax on their taxable income. We have formed
and made elections for several TRSs. See "Other Tax Consequences--Taxable REIT
Subsidiaries."

Income Tests

     We must satisfy two gross income tests annually to maintain our
qualification as a REIT. First, at least 75% of our gross income for each
taxable year must consist of defined types of income that we derive, directly or
indirectly, from investments relating to real property or mortgages on real
property or temporary investment income. Qualifying income for purposes of that
75% gross income test generally includes:

     .    rents from real property;

     .    interest on debt secured by mortgages on real property or on interests
          in real property;

     .    dividends or other distributions on and gain from the sale of shares
          in other REITs; and

     .    gain from the sale of real estate assets.

                                       13



     Second, in general, at least 95% of our gross income for each taxable year
must consist of income that is qualifying income for purposes of the 75% gross
income test, other types of dividends and interest, gain from the sale or
disposition of stock or securities, income from certain hedging transactions, or
any combination of the foregoing. Gross income from our sale of property that we
hold primarily for sale to customers in the ordinary course of business is
excluded from both income tests. The following paragraphs discuss the specific
application of the gross income tests to us.

     Rents from Real Property. Rent that we receive from real property that we
own and lease to tenants will qualify as "rents from real property," which is
qualifying income for purposes of the 75% and 95% gross income tests, only if
the following conditions are met:

     .    First, the rent must not be based, in whole or in part, on the income
          or profits of any person, but may be based on a fixed percentage or
          percentages of receipts or sales.

     .    Second, neither we nor a direct or indirect owner of 10% or more of
          our stock may own, actually or constructively, 10% or more of a tenant
          from whom we receive rent (a "Related Party Tenant").

     .    Third, all of the rent received under a lease of real property will
          not qualify as "rents from real property" unless the rent attributable
          to the personal property leased in connection with such lease is no
          more than 15% of the total rent received under the lease. The rent
          attributable to the personal property contained in a hotel is the
          amount that bears the same ratio to total rent for the taxable year as
          the average of the fair market values of the personal property at the
          beginning and at the end of the taxable year bears to the average of
          the aggregate fair market values of both the real and personal
          property contained in the hotel at the beginning and at the end of
          such taxable year (the "personal property ratio"). Prior to January 1,
          2001, the personal property ratio was computed based on relative
          adjusted tax bases instead of fair market values.

     .    Fourth, we generally must not operate or manage our real property or
          furnish or render services to our tenants, other than through an
          "independent contractor" who is adequately compensated and from whom
          we do not derive revenue. However, we need not provide services
          through an "independent contractor," but instead may provide services
          directly to our tenants, if the services are "usually or customarily
          rendered" in connection with the rental of space for occupancy only
          and are not considered to be provided for the tenants' convenience. In
          addition, we may provide a minimal amount of "non-customary" services
          to the tenants of a property, other than through an independent
          contractor, as long as our income from the services does not exceed 1%
          of our income from the related property. Furthermore, we may own up to
          100% of the stock of a TRS, which may provide customary and
          noncustomary services to our tenants without tainting our rental
          income from the related properties. See "--Taxable REIT Subsidiaries."

     We do not receive any rent that is based on the income or profits of any
person. In addition, we do not own, directly or indirectly, 10% or more of any
tenant. Furthermore, we believe that any personal property rented in connection
with our apartment facilities is well within the 15% restriction. Finally, we do
not provide services, other than within the 1% de minimis exception described
above, to our tenants that are not customarily furnished or rendered in
connection with the rental of the apartment units, other than through an
independent contractor.

                                       14



     Our investment in apartment communities in major part gives rise to rental
income that is qualifying income for purposes of the 75% and 95% gross income
tests. Gains on sales of apartment communities, other than from prohibited
transactions, as described below, or of our interest in a partnership generally
will be qualifying income for purposes of the 75% and 95% gross income tests. We
anticipate that income on our other investments will not result in our failing
the 75% or 95% gross income test for any year.

Prohibited Transactions.

     A REIT will incur a 100% tax on the net income derived from any sale or
other disposition of property, other than foreclosure property, that the REIT
holds primarily for sale to customers in the ordinary course of a trade or
business. Whether a REIT holds an asset "primarily for sale to customers in the
ordinary course of a trade or business" depends on the facts and circumstances
in effect from time to time, including those related to a particular asset. We
believe that none of our assets is held for sale to customers and that a sale of
any such asset would not be in the ordinary course of the owning entity's
business. We will attempt to comply with the terms of safe-harbor provisions in
the federal income tax laws prescribing when an asset sale will not be
characterized as a prohibited transaction. We cannot provide assurance, however,
that we can comply with such safe-harbor provisions or that we will avoid owning
property that may be characterized as property held "primarily for sale to
customers in the ordinary course of a trade or business."

Hedging Transactions.

     From time to time, we may enter into hedging transactions with respect to
one or more of our assets or liabilities. Our hedging activities may include
entering into interest rate swaps, caps, and floors, options to purchase such
items, and futures and forward contracts. To the extent that we enter into an
interest rate swap or cap contract, option, futures contract, forward rate
agreement, or any similar financial instrument to hedge our indebtedness
incurred to acquire or carry "real estate assets," any periodic income or gain
from the disposition of such contract should be qualifying income for purposes
of the 95% gross income test, but not the 75% gross income test. To the extent
that we hedge with other types of financial instruments, or in other situations,
it is not entirely clear how the income from those transactions will be treated
for purposes of the gross income tests. We intend to structure any hedging
transactions in a manner that does not jeopardize our status as a REIT.

Failure to Satisfy Gross Income Tests.

     If we fail to satisfy one or both of the gross income tests for any taxable
year, we nevertheless may qualify as a REIT for such year if we qualify for
relief under certain provisions of the federal income tax laws. Those relief
provisions generally will be available if:

     .    our failure to meet such tests is due to reasonable cause and not due
          to willful neglect;

     .    we attach a schedule of the sources of our income to our tax return;
          and

     .    any incorrect information on the schedule was not due to fraud with
          intent to evade tax.

     We cannot predict, however, whether in all circumstances we would qualify
for the relief provisions. In addition, as discussed above in "--Taxation of
United Dominion," even if the relief provisions apply, we would incur a 100% tax
on the gross income attributable to the greater of the

                                       15



amounts by which we fail the 75% and 95% gross income tests, multiplied by a
fraction intended to reflect our profitability.

Asset Tests

     To maintain our qualification as a REIT, we also must satisfy the following
asset tests at the close of each quarter of each taxable year:

     .    First, at least 75% of the value of our total assets must consist of:

          -    cash or cash items, including certain receivables;

          -    government securities;

          -    interests in real property, including leaseholds and options to
               acquire real property and leaseholds;

          -    interests in mortgages on real property;

          -    stock in other REITs; and

          -    investments in stock or debt instruments during the one-year
               period following our receipt of new capital that we raise through
               equity offerings or offerings of debt with at least a five-year
               term.

     .    Second, of our investments not included in the 75% asset class, the
          value of our interest in any one issuer's securities may not exceed 5%
          of the value of our total assets.

     .    Third, we may not own more than 10% of the voting power or value of
                                                                  --
          any one issuer's outstanding securities.

     .    Fourth, no more than 20% of the value of our total assets may consist
          of the securities of one or more TRSs.

     .    Fifth, no more than 25% of the value of our total assets may consist
          of the securities of TRSs and other non-TRS taxable subsidiaries and
          other assets that are not qualifying assets for purposes of the 75%
          asset test.

     For purposes of the second and third asset tests, the term "securities"
does not include stock in another REIT, equity or debt securities of a qualified
REIT subsidiary or TRS, or equity interests in any partnership. The term
"securities," however, generally includes debt securities issued by a
partnership, except that debt securities of a partnership are not treated as
"securities" for purposes of the 10% value test if we own at least a 20% profits
interest in the partnership and such debt is classified as "straight debt" for
purposes of the REIT rules.

     If we should fail to satisfy the asset tests at the end of a calendar
quarter, we would not lose our REIT status if (1) we satisfied the asset tests
at the close of the preceding calendar quarter and (2) the discrepancy between
the value of our assets and the asset test requirements arose from changes in
the market values of our assets and was not wholly or partly caused by the
acquisition of one or more non-


                                       16



qualifying assets. If we did not satisfy the condition described in clause (2)
of the preceding sentence, we still could avoid disqualification as a REIT by
eliminating any discrepancy within 30 days after the close of the calendar
quarter in which the discrepancy arose.

Distribution Requirements

     Each taxable year, we must distribute dividends, other than capital gain
dividends and deemed distributions of retained capital gain, to our shareholders
in an aggregate amount at least equal to:

     .    the sum of (1) 90% of our "REIT taxable income," computed without
          regard to the dividends paid deduction and our net capital gain or
          loss, and (2) 90% of our after-tax net income, if any, from
          foreclosure property; minus

     .    the sum of certain items of non-cash income.

     We must pay such distributions in the taxable year to which they relate, or
in the following taxable year if we declare the distribution before we timely
file our federal income tax return for such year and pay the distribution on or
before the first regular dividend payment date after such declaration.

     We will pay federal income tax on taxable income, including net capital
gain, that we do not distribute to our shareholders. Furthermore, if we fail to
distribute during a calendar year, or by the end of January following such
calendar year in the case of distributions with declaration and record dates
falling in the last three months of the calendar year, at least the sum of:

     .    85% of our REIT ordinary income for such year;

     .    95% of our REIT capital gain income for such year; and

     .    any undistributed taxable income from prior periods,

we will incur a 4% nondeductible excise tax on the excess of such required
distribution over the amounts we actually distributed. We may elect to retain
and pay income tax on the net long-term capital gain we receive in a taxable
year. See "--Taxation of Taxable U.S. Shareholders." If we so elect, we will be
treated as having distributed any such retained amount for purposes of the 4%
excise tax described above. We have made, and we intend to continue to make,
timely distributions sufficient to satisfy the annual distribution requirements.

     It is possible that, from time to time, we may experience timing
differences between (1) the actual receipt of income and actual payment of
deductible expenses and (2) the inclusion of that income and deduction of such
expenses in arriving at our REIT taxable income. For example, we may not deduct
recognized capital losses from our "REIT taxable income." Further, it is
possible that, from time to time, we may be allocated a share of net capital
gain attributable to the sale of depreciated property that exceeds our allocable
share of cash attributable to that sale. As a result of the foregoing, we may
have less cash than is necessary to distribute all of our taxable income and
thereby avoid corporate income tax and the excise tax imposed on certain
undistributed income. In such a situation, we may need to borrow funds or issue
additional common or preferred stock.

     Under certain circumstances, we may be able to correct a failure to meet
the distribution requirement for a year by paying "deficiency dividends" to our
shareholders in a later year. We may include such deficiency dividends in our
deduction for dividends paid for the earlier year. Although we

                                       17



may be able to avoid income tax on amounts distributed as deficiency dividends,
we will be required to pay interest to the Internal Revenue Service based upon
the amount of any deduction we take for deficiency dividends.

Recordkeeping Requirements

     We must maintain certain records in order to qualify as a REIT. In
addition, to avoid a monetary penalty, we must request on an annual basis
information from our shareholders designed to disclose the actual ownership of
our outstanding stock. We have complied, and intend to continue to comply, with
such requirements.

Failure to Qualify

     If we were to fail to qualify as a REIT in any taxable year, and no relief
provision applied, we would be subject to federal income tax and any applicable
alternative minimum tax on our taxable income at regular corporate rates. In
calculating our taxable income in a year in which we failed to qualify as a
REIT, we would not be able to deduct amounts paid out to shareholders. In fact,
we would not be required to distribute any amounts to shareholders in such year.
In such event, to the extent of our current and accumulated earnings and
profits, all distributions to shareholders would be taxable as ordinary income.
Subject to certain limitations of the federal income tax laws, corporate
shareholders might be eligible for the dividends received deduction. Unless we
qualified for relief under specific statutory provisions, we also would be
disqualified from taxation as a REIT for the four taxable years following the
year during which we ceased to qualify as a REIT. We cannot predict whether in
all circumstances we would qualify for such statutory relief.

Taxation of Taxable U.S. Shareholders

     As long as we qualify as a REIT, a taxable "U.S. shareholder" must take
into account distributions that are made out of our current or accumulated
earnings and profits and that we do not designate as capital gain dividends or
retained long-term capital gain as ordinary income. A U.S. shareholder will not
qualify for the dividends received deduction generally available to
corporations. As used herein, the term "U.S. shareholder" means a holder of our
common stock that for U.S. federal income tax purposes is:

     .    a citizen or resident of the United States;

     .    a corporation or partnership (including an entity treated as a
          corporation or partnership for U.S. federal income tax purposes)
          created or organized in or under the laws of the United States or of a
          political subdivision thereof;

     .    an estate whose income is subject to U.S. federal income taxation
          regardless of its source; or

     .    any trust if (1) a U.S. court is able to exercise primary supervision
          over the administration of such trust and one or more U.S. persons
          have the authority to control all substantial decisions of the trust
          or (2) it has a valid election in place to be treated as a U.S.
          person.

     A U.S. shareholder generally will recognize distributions that we designate
as capital gain dividends as long-term capital gain without regard to the period
for which the U.S. shareholder has held

                                       18



our common stock. We generally will designate our capital gain dividends as
either 20% or 25% rate distributions. A corporate U.S. shareholder, however, may
be required to treat up to 20% of certain capital gain dividends as ordinary
income.

     We may elect to retain and pay income tax on the net long-term capital gain
that we receive in a taxable year. In that case, a U.S. shareholder would be
taxed on its proportionate share of our undistributed long-term capital gain.
The U.S. shareholder would receive a credit or refund for its proportionate
share of the tax we paid. The U.S. shareholder would increase the basis in its
stock by the amount of its proportionate share of our undistributed long-term
capital gain, minus its share of the tax we paid.

     A U.S. shareholder will not incur tax on a distribution in excess of our
current and accumulated earnings and profits if such distribution does not
exceed the adjusted tax basis of the U.S. shareholder's common stock. Instead,
such distribution will reduce the adjusted tax basis of such common stock. A
U.S. shareholder will recognize a distribution in excess of both our current and
accumulated earnings and profits and the U.S. shareholder's adjusted tax basis
in its common stock as long-term capital gain, or short-term capital gain if the
common stock has been held for one year or less, assuming the common stock is a
capital asset in the hands of the U.S. shareholder. In addition, if we declare a
distribution in October, November, or December of any year that is payable to a
U.S. shareholder of record on a specified date in any such month, such
distribution shall be treated as both paid by us and received by the U.S.
shareholder on December 31 of such year, provided that we actually pay the
distribution during January of the following calendar year.

     Shareholders may not include in their individual income tax returns any of
our net operating losses or capital losses. Instead, we would carry over such
losses for potential offset against our future income generally. Taxable
distributions from us and gain from the disposition of our common stock will not
be treated as passive activity income and, therefore, shareholders generally
will not be able to apply any "passive activity losses," such as losses from
certain types of limited partnerships in which the shareholder is a limited
partner, against such income. In addition, taxable distributions from us and
gain from the disposition of the common stock generally will be treated as
investment income for purposes of the investment interest limitations. We will
notify shareholders after the close of our taxable year as to the portions of
the distributions attributable to that year that constitute ordinary income,
return of capital, and capital gain.

Taxation of U.S. Shareholders on the Disposition of Common Stock

     In general, a U.S. shareholder who is not a dealer in securities must treat
any gain or loss realized upon a taxable disposition of our common stock as
long-term capital gain or loss if the U.S. shareholder has held the common stock
for more than one year and otherwise as short-term capital gain or loss.
However, a U.S. shareholder must treat any loss upon a sale or exchange of
common stock held by such shareholder for six months or less as a long-term
capital loss to the extent of any actual or deemed distributions from us that
such U.S. shareholder previously has characterized as long-term capital gain.
All or a portion of any loss that a U.S. shareholder realizes upon a taxable
disposition of the common stock may be disallowed if the U.S. shareholder
purchases other shares of common stock within 30 days before or after the
disposition.

Capital Gains and Losses

     A taxpayer generally must hold a capital asset for more than one year for
gain or loss derived from its sale or exchange to be treated as long-term
capital gain or loss. The highest marginal individual

                                       19



income tax rate is 38.6% for the period from January 1, 2002 to December 31,
2003, 37.6% for the period from January 1, 2004 to December 31, 2005, and 35%
for the period from January 1, 2006 to December 31, 2010. The maximum tax rate
on long-term capital gain applicable to non-corporate taxpayers is 20% for sales
and exchanges of assets held for more than one year. The maximum tax rate on
long-term capital gain from the sale or exchange of "section 1250 property," or
depreciable real property, is 25% to the extent that such gain would have been
treated as ordinary income if the property were "section 1245 property." With
respect to distributions that we designate as capital gain dividends and any
retained capital gain that we are deemed to distribute, we generally may
designate whether such a distribution is taxable to our non-corporate
shareholders at a 20% or 25% rate. Thus, the tax rate differential between
capital gain and ordinary income for non-corporate taxpayers may be significant.
In addition, the characterization of income as capital gain or ordinary income
may affect the deductibility of capital losses. A non-corporate taxpayer may
deduct capital losses not offset by capital gains against its ordinary income
only up to a maximum annual amount of $3,000. A non-corporate taxpayer may carry
forward unused capital losses indefinitely. A corporate taxpayer must pay tax on
its net capital gain at ordinary corporate rates. A corporate taxpayer may
deduct capital losses only to the extent of capital gains, with unused losses
being carried back three years and forward five years.

Information Reporting Requirements and Backup Withholding

     We will report to our shareholders and to the Internal Revenue Service the
amount of distributions we pay during each calendar year, and the amount of tax
we withhold, if any. Under the backup withholding rules, a shareholder may be
subject to backup withholding at the rate of up to 30% with respect to
distributions unless such 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 the
          applicable requirements of the backup withholding rules.

     A shareholder who does not provide us with its correct taxpayer
identification number also may be subject to penalties imposed by the Internal
Revenue Service. Any amount paid as backup withholding will be creditable
against the shareholder's income tax liability. In addition, we may be required
to withhold a portion of capital gain distributions to any shareholders who fail
to certify their non-foreign status to us. See "--Taxation of Non-U.S.
Shareholders."

Taxation of Tax-Exempt Shareholders

     Tax-exempt entities, including qualified employee pension and profit
sharing trusts and individual retirement accounts and annuities, generally are
exempt from federal income taxation. However, they are subject to taxation on
their unrelated business taxable income. While many investments in real estate
generate unrelated business taxable income, the Internal Revenue Service has
issued a published ruling that dividend distributions from a REIT to an exempt
employee pension trust do not constitute unrelated business taxable income,
provided that the exempt employee pension trust does not otherwise use the
shares of the REIT in an unrelated trade or business of the pension trust. Based
on that ruling, amounts that we distribute to tax-exempt shareholders generally
should not constitute unrelated business taxable income. However, if a
tax-exempt shareholder were to finance its acquisition of our common stock with
debt, a portion of the income that it receives from us would constitute
unrelated business taxable income pursuant to the "debt-financed property"
rules. Furthermore, social

                                       20



clubs, voluntary employee benefit associations, supplemental unemployment
benefit trusts, and qualified group legal services plans that are exempt from
taxation under special provisions of the federal income tax laws are subject to
different unrelated business taxable income rules, which generally will require
them to characterize distributions that they receive from us as unrelated
business taxable income. Finally, in certain circumstances, a qualified employee
pension or profit sharing trust that owns more than 10% of our stock is required
to treat a percentage of the dividends that it receives from us as unrelated
business taxable income. Such percentage is equal to the gross income that we
derive from an unrelated trade or business, determined as if we were a pension
trust, divided by our total gross income for the year in which we pay the
dividends. That rule applies to a pension trust holding more than 10% of our
stock only if:

     .    the percentage of our dividends that the tax-exempt trust would be
          required to treat as unrelated business taxable income is at least 5%;

     .    we qualify as a REIT by reason of the modification of the rule
          requiring that no more than 50% of our stock be owned by five or fewer
          individuals that allows the beneficiaries of the pension trust to be
          treated as holding our stock in proportion to their actuarial
          interests in the pension trust (see "--Requirements for Qualification"
          above); and

     .    either (1) one pension trust owns more than 25% of the value of our
          stock or (2) a group of pension trusts individually holding more than
          10% of the value of our stock collectively owns more than 50% of the
          value of our stock.

Taxation of Non-U.S. Shareholders

     The rules governing U.S. federal income taxation of nonresident alien
individuals, foreign corporations, foreign partnerships, and other foreign
shareholders (collectively, "non-U.S. shareholders") are complex. This section
is only a summary of such rules. We urge non-U.S. shareholders to consult their
own tax advisors to determine the impact of federal, state, and local income tax
laws on ownership of our common stock, including any reporting requirements.

     A non-U.S. shareholder that receives a distribution that is not
attributable to gain from our sale or exchange of U.S. real property interests,
as defined below, and that we do not designate as a capital gain dividend or
retained capital gain will recognize ordinary income to the extent that we pay
such distribution out of our current or accumulated earnings and profits. A
withholding tax equal to 30% of the gross amount of the distribution ordinarily
will apply to such distribution unless an applicable tax treaty reduces or
eliminates the tax. However, if a distribution is treated as effectively
connected with the non-U.S. shareholder's conduct of a U.S. trade or business,
the non-U.S. shareholder generally will be subject to federal income tax on the
distribution at graduated rates, in the same manner as U.S. shareholders are
taxed with respect to such distributions. A non-U.S. shareholder that is a
corporation also may be subject to the 30% branch profits tax with respect to
the distribution. We plan to withhold U.S. income tax at the rate of 30% on the
gross amount of any such distribution paid to a non-U.S. shareholder unless
either:

     .    a lower treaty rate applies and the non-U.S. shareholder files an
          IRS Form W-8BEN evidencing eligibility for that reduced rate with us;
          or

     .    the non-U.S. shareholder files an IRS Form W-8ECI with us claiming
          that the distribution is effectively connected income.


                                       21



     A non-U.S. shareholder will not incur tax on a distribution in excess of
our current and accumulated earnings and profits if such distribution does not
exceed the adjusted basis of its common stock. Instead, such a distribution will
reduce the adjusted basis of such common stock. A non-U.S. shareholder will be
subject to tax on a distribution that exceeds both our current and accumulated
earnings and profits and the adjusted basis of its common stock, if the non-U.S.
shareholder otherwise would be subject to tax on gain from the sale or
disposition of its common stock, as described below. Because we generally cannot
determine at the time we make a distribution whether or not the distribution
will exceed our current and accumulated earnings and profits, we normally will
withhold tax on the entire amount of any distribution at the same rate as we
would withhold on a dividend. However, a non-U.S. shareholder may obtain a
refund of amounts that we withhold if we later determine that a distribution in
fact exceeded our current and accumulated earnings and profits.

     We must withhold 10% of any distribution that exceeds our current and
accumulated earnings and profits. Consequently, although we intend to withhold
at a rate of 30% on the entire amount of any distribution, to the extent that we
do not do so, we will withhold at a rate of 10% on any portion of a distribution
not subject to withholding at a rate of 30%.

     For any year in which we qualify as a REIT, a non-U.S. shareholder will
incur tax on distributions that are attributable to gain from our sale or
exchange of "U.S. real property interests" under special provisions of the
federal income tax laws referred to as FIRPTA. The term "U.S. real property
interests" includes certain interests in real property and stock in corporations
at least 50% of whose assets consists of interests in real property. Under those
rules, a non-U.S. shareholder is taxed on distributions attributable to gain
from sales of U.S. real property interests as if such gain were effectively
connected with a U.S. business of the non-U.S. shareholder. A non-U.S.
shareholder thus would be taxed on such a distribution at the normal capital
gains rates applicable to U.S. shareholders, subject to applicable alternative
minimum tax and a special alternative minimum tax in the case of a nonresident
alien individual. A non-U.S. corporate shareholder not entitled to treaty relief
or exemption also may be subject to the 30% branch profits tax on such a
distribution. We must withhold 35% of any distribution that we could designate
as a capital gain dividend. A non-U.S. shareholder may receive a credit against
its tax liability for the amount we withhold.

     A non-U.S. shareholder generally will not incur tax under FIRPTA as long as
at all times non-U.S. persons hold, directly or indirectly, less than 50% in
value of our stock. We cannot assure you that that test will be met. However, a
non-U.S. shareholder that owned, actually or constructively, 5% or less of our
common stock at all times during a specified testing period will not incur tax
under FIRPTA if the common stock is "regularly traded" on an established
securities market. Because our common stock is regularly traded on an
established securities market, a non-U.S. shareholder will not incur tax under
FIRPTA unless it owns more than 5% of our common stock. If the gain on the sale
of the common stock were taxed under FIRPTA, a non-U.S. shareholder would be
taxed in the same manner as U.S. shareholders with respect to such gain, subject
to applicable alternative minimum tax, a special alternative minimum tax in the
case of nonresident alien individuals, and the possible application of the 30%
branch profits tax in the case of non-U.S. corporations. Furthermore, a non-U.S.
shareholder will incur tax on gain not subject to FIRPTA if (1) the gain is
effectively connected with the non-U.S. shareholder's U.S. trade or business, in
which case the non-U.S. shareholder will be subject to the same treatment as
U.S. shareholders with respect to such gain, or (2) the non-U.S. shareholder is
a nonresident alien individual who was present in the U.S. for 183 days or more
during the taxable year and has a "tax home" in the United States, in which case
the non-U.S. shareholder will incur a 30% tax on his capital gains.

                                       22



Other Tax Consequences

Taxable REIT Subsidiaries

         As described above, we may own up to 100% of the stock of one or more
TRSs. A TRS is a fully taxable corporation. A TRS may provide services to our
tenants without tainting our rent from our tenants and perform activities
unrelated to our tenants, such as third-party management, development, and other
independent business activities. We and a subsidiary must elect for the
subsidiary to be treated as a TRS. A corporation of which a TRS directly or
indirectly owns more than 35% of the voting power or value of the stock will
automatically be treated as a TRS. Overall, no more than 20% of the value of our
assets may consist of securities of one or more TRSs, and no more than 25% of
the value of our assets may consist of the securities of TRSs and other non-TRS
taxable subsidiaries and other assets that are not qualifying assets for
purposes of the 75% asset test.

         A TRS may not directly or indirectly operate or manage any hotels or
health care facilities or provide rights to any brand name under which any hotel
or health care facility is operated. In addition, we may rent space at our
properties to a TRS if at least 90% of the leased space in the property is
leased to persons other than TRSs and Related Party Tenants and the amount paid
by the TRS to rent space at the property is substantially comparable to rents
paid by other tenants of the property for comparable space.

         The TRS rules limit the deductibility of interest paid or accrued by a
TRS to us to assure that the TRS is subject to an appropriate level of corporate
taxation. Further, the rules impose a 100% excise tax on transactions between a
TRS and us or our tenants that are not conducted on an arm's-length basis.

         We have formed and made elections for several TRSs. We believe that the
value of the stock of our TRSs constitutes less than 20% of the value of our
assets and that all transactions between us and our TRSs are conducted on an
arm's-length basis.

State and Local Taxes

         We and/or you may be subject to state and local tax in various states
and localities, including those states and localities in which we or you
transact business, own property, or reside. The state and local tax treatment in
such jurisdictions may differ from the federal income tax treatment described
above. Consequently, you should consult your own tax advisor regarding the
effect of state and local tax laws upon an investment in our common stock.

                              PLAN OF DISTRIBUTION

         The shares being offered by the selling shareholder have been or may be
issued by us upon the selling shareholder's conversion of 8,000,000 shares of
our Series D Cumulative Convertible Preferred Stock held by the selling
shareholder. These shares of preferred stock were issued pursuant to an
exemption from the registration provisions of the Securities Act. The selling
shareholder represented to us that it was acquiring the shares for investment
and with no present intention of distributing the shares.

         We will not receive any proceeds from the sale of the common stock
covered by this prospectus. The selling shareholder may sell its shares directly
or through broker-dealers or underwriters who may act solely as agents or who
may acquire shares as principals.

         The shares may be sold in one or more transactions at:


                                       23



        .        fixed prices;

        .        prevailing market prices at the time of sale;

        .        prices related to the prevailing market prices;

        .        varying prices determined at the time of sale; or

        .        negotiated prices.

        The methods by which the shares may be sold include:

        .        a block trade in which the broker-dealer so engaged will
                 attempt to sell the offered securities as agent but may
                 position and resell a portion of the block as principal to
                 facilitate the transaction;

        .        purchases by a broker-dealer as principal and resale by such
                 broker-dealer for its account pursuant to this prospectus;

        .        ordinary brokerage transactions and transactions in which the
                 broker solicits purchasers;

        .        privately negotiated transactions;

        .        put or call transactions;

        .        short-sales; and

        .        underwritten transactions.

Usual and customary or specifically negotiated underwriting discounts and
concessions or brokerage fees or commissions may be paid by the selling
shareholder in connection with such sales.

     The aggregate proceeds to the selling shareholder from the sale of the
shares will be the purchase price of the common stock sold less the aggregate
agents' commissions if any, and other expenses of issuance and distribution not
borne by us. The selling shareholder 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 such shares by them
and any commissions received by any such dealers or agents might be deemed to be
underwriting discounts and commissions under the Securities Act.

     To the extent required, the specific shares of common stock to be sold, the
name of the selling shareholder, purchase price, public offering price, the
names of any agent, dealer or underwriter, and any applicable commission or
discount with respect to a particular offering will be set forth in an
accompanying prospectus supplement.

     We have agreed to bear certain expenses of registration of the common stock
under the federal and state securities laws and of any offering and sale
hereunder but not certain expenses, such as commissions of dealers or agents,
and fees attributable to the sale of the shares.


                                       24



         We also have agreed to indemnify the selling shareholder from certain
damages or liabilities arising out of or based upon any untrue statement of a
material fact contained in, or material omission from, the Registration
Statement, except to the extent such untrue statement or omission was made in
the Registration Statement in reliance upon written information furnished by the
selling shareholder.

         This offering will terminate on the earlier of:

         .     the date that all of the shares under this prospectus may be sold
               in accordance with Rule 144(k) under the Securities Act of 1933;
               or

         .     the date on which all shares offered hereby have been sold by the
               selling shareholder.

         Any securities covered by this prospectus that qualify for sale
pursuant to Rule 144 under the Securities Act may be sold under that rule rather
than pursuant to this prospectus.

         There can be no assurance that the selling shareholder will sell any or
all of the shares of common stock offered hereunder.

                                  LEGAL MATTERS

         The validity of the shares of common stock offered will be passed upon
for us by Hunton & Williams.

Item 15. Indemnification of Officers and Directors

          Our directors and officers may be indemnified against liabilities,
fines, penalties, and claims imposed upon or asserted against them as provided
in the Virginia Stock Corporation Act and our Articles of Incorporation. Such
indemnification covers all costs and expenses reasonably incurred by a director
or officer. The board of directors, by a majority vote of a quorum of
disinterested directors or, under certain circumstances, independent counsel
appointed by the board of directors, must determine that the director or officer
seeking indemnification was not guilty of willful misconduct or a knowing
violation of the criminal law. In addition, the Virginia Stock Corporation Act
and our Articles of Incorporation may under certain circumstances eliminate the
liability of directors and officers in a shareholder or derivative proceeding.

          If the person involved is not a director or officer of United
Dominion, the board of directors may cause the company to indemnify to the same
extent allowed for directors and officers of the company such person who was or
is a party to a proceeding, by reason of the fact that he is or was an employee
or agent of United Dominion, or is or was serving at the request of the company
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise.

Item 17.       Undertakings

      (a)      The undersigned registrant hereby undertakes:

               (1)      To file, during any period in which offers or sales are
      being made, a post-effective amendment to this Registration Statement:

                        (i)  To include any prospectus required by Section
               10(a)(3) of the Securities Act;

                        (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)(1)(i) and
               (a)(1)(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 Section 15(d) of the Exchange Act that are
               incorporated by reference in the Registration Statement.

               (2)      That, for the purpose of determining any liability under
      the Securities Act, 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.



                        (3) To remove from registration by means of a
               post-effective amendment any of the securities being registered
               which remain unsold at the termination of the offering.

               (b)      The undersigned registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act, each filing of
the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in this registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

               (c)      Insofar as indemnification for liabilities arising under
the Securities Act may be permitted to directors, officers and controlling
persons of the registrant pursuant to the provisions of the Virginia Code, the
Articles of Incorporation or By-laws of the registrant or resolutions of the
Board of Directors of the registrant adopted pursuant thereto, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act, 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
Act and will be governed by the final adjudication of such issue.



                                   SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, the
registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-3 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the county of Douglas, State of Colorado on the 23rd day of
April, 2002.
