     As used herein, the term "Company" includes Equity Residential Properties
Trust and those entities owned or controlled by it (collectively, the
"Subsidiaries"), as the survivor of the mergers between Equity Residential
Properties Trust ("EQR") and each of Wellsford Residential Property Trust
("Wellsford") and Evans Withycombe Residential, Inc. ("EWR") and each of EQR,
Wellsford and EWR as predecessors to the Company, unless the context indicates
otherwise.

                                   THE COMPANY

GENERAL

     Equity Residential Properties Trust, one of the largest publicly traded
REITs (based on the aggregate market value of its outstanding equity
capitalization), is a self-administered and self-managed equity REIT. EQR was
organized in March 1993 and commenced operations as a publicly traded company on
August 18, 1993 upon completion of its initial public offering (the "EQR IPO").
EQR was formed to continue the multifamily property business objectives and
acquisition strategies of certain affiliated entities controlled by Mr. Samuel
Zell, Chairman of the Board of Trustees of the Company. These entities had been
engaged in the acquisition, ownership and operation of multifamily properties
since 1969. In May 1997, EQR completed the acquisition of the multifamily
property business of Wellsford through the tax free merger of EQR and Wellsford.
In December 1997, EQR completed the acquisition of the multifamily property
business of EWR through the tax free merger of EWR and the Company. The
Company's senior executives average over 24 years of experience in the
multifamily property business.

     The Company is the largest publicly traded REIT owner of multifamily
properties (based on the number of apartment units owned and total revenues
earned). All of the Company's interests in its multifamily properties (the
"Properties") are held or controlled directly or indirectly by, and
substantially all of its operations relating to the Properties are conducted
through, ERP Operating Limited Partnership (the "Operating Partnership"). The
Operating Partnership currently has eight classes of limited partnership
interests outstanding: (i) partnership interests ("OP Units"), which may be
exchanged by the holders thereof for either Common Shares on a one-for-one basis
or, at the Company's option, cash; (ii) 9 3/8% Series A Cumulative Redeemable
Preference Units ("9 3/8% Series A Preference Units"); (iii) 9 1/8% Series B
Cumulative Redeemable Preference Units ("9 1/8% Series B Preference Units");
(iv) 9 1/8% Series C Cumulative Redeemable Preference Units ("9 1/8% Series C
Preference Units"); (v) 8.60% Series D Cumulative Redeemable Preference Units
("8.60% Series D Preference Units"); (vi) Series E Cumulative Convertible
Preference Units ("Series E Preference Units"), (vii) 9.65% Series F Cumulative
Redeemable Preference Units ("9.65% Series F Preference Units") and (viii) 7
1/4% Series G Convertible Cumulative Preference Units ("7 1/4% Series G
Preference Units"). The 9 3/8% Series A Preference Units, the 9 1/8% Series B
Preference Units, the 9 1/8% Series C Preference Units, the 8.60% Series D
Preference Units, the Series E Preference Units, the 9.65% Series F Preference
Units and the 7 1/4% Series G Preference Units are owned by the Company and
mirror the payments of distributions, including accrued and unpaid distributions
upon redemption, and of the liquidating preference amount of the Company's 9
3/8% Series A Cumulative Redeemable Preferred Shares of Beneficial Interest,
$.01 par value per share (the "Series A Preferred Shares"), the Company's 9 1/8%
Series B Cumulative Redeemable Preferred Shares of Beneficial Interest, $.01 par
value per share (the "Series B Preferred Shares"), the Company's 9 1/8% Series C

Cumulative Redeemable Preferred Shares of Beneficial Interest, $.01 par value
per share (the "Series D Preferred Shares"), the Company's Series E Cumulative
Convertible Preferred Shares of Beneficial Interest, $.01 par value per share
(the "Series E Preferred Shares"), the Company's 9.65% Series F Preferred Shares
of Beneficial Interest, $.01 par value per share (the "Series F Preferred
Shares"), and the Company's 7 1/4% Series G Convertible Cumulative Preferred
Shares of Beneficial Interest, $.01 par value per share (the "Series G Preferred
Shares" and, collectively with the Series A Preferred Shares, the Series B
Preferred Shares, the Series C Preferred Shares, the Series D Preferred Shares,
the Series E Preferred Shares and the Series F Preferred Shares, the
"Outstanding Preferred Shares"), respectively. The Company controls the
Operating Partnership as the sole general partner and, as of January 28, 1998
owned approximately 91% of all of the Operating Partnership's outstanding
partnership interests, excluding the 9 3/8% Series A Preference Units, the 9
1/8% Series B Preference Units, the 9 1/8% Series C Preference Units, the 8.60%
Series D Preference Units, the Series E Preference Units, the 9.65% Series F
Preference Units and the 7 1/4% Series G Preference Units. It is the Company's
policy that Equity Residential Properties Trust shall not incur indebtedness
other than short-term trade, employee compensation, dividends payable or similar
indebtedness that will be paid in the ordinary course of business, and that
indebtedness shall instead be incurred by the Operating Partnership to the
extent necessary to fund the business activities conducted by the Operating
Partnership and its subsidiaries.

ADVERSE CONSEQUENCES OF DEBT FINANCING AND PREFERRED SHARES

     General Risks. As of December 31, 1997, the Properties were subject to
approximately $1.6 billion of mortgage indebtedness and the Company's total debt
equaled approximately $2.9 billion, $912.8 million of which was floating rate
debt. In addition, from June 1995 through October 1997, the Company issued the
Outstanding Preferred Shares pursuant to preferred share and depositary share
offerings. The Company used the proceeds from the Preferred Share Offerings to
repay indebtedness and to acquire additional Properties. The Company is subject
to the risks normally associated with debt or preferred equity financing,
including the risk that the Company's cash flow will be insufficient to meet
required payments of principal and interest, the risk that existing indebtedness
may not be refinanced or that the terms of such refinancing will not be as
favorable as the terms of current indebtedness and the risk that necessary
capital expenditures for such purposes as renovations and other improvements may
not be financed on favorable terms or at all. If the Company were unable to
refinance its indebtedness on acceptable terms, or at all, the Company might be
forced to dispose of one or more of the Properties on disadvantageous terms,
which might result in losses to the Company and might adversely affect the cash
available for distributions to shareholders. If interest rates or other factors
at the time of the refinancing result in higher interest rates upon refinancing,
the Company's interest expense would increase, which would affect the Company's
ability to make distributions to its shareholders. Furthermore, if a Property is
mortgaged to secure payment of indebtedness and the Company is unable to meet
mortgage payments, the mortgagee could foreclose upon the Property, appoint a
receiver and receive an assignment of rents and leases or pursue other remedies,
all with a consequent loss of income and asset value to the Company.
Foreclosures could also create taxable income without accompanying cash
proceeds, thereby hindering the Company's ability to meet the REIT distribution
requirements of the Internal Revenue Code of 1986, as amended (the "Code").

     Restrictions on the Company's Activities. A substantial portion of the
Company's debt was issued pursuant to certain indentures (the "Indentures")
which restrict the amount of indebtedness (including acquisition financing) the
Company may incur. Accordingly, in the event that the Company is unable to raise
additional equity or borrow money because of the debt restrictions in the
Indentures, the Company's ability to acquire additional properties may be
limited. If the Company is unable to acquire additional properties, its ability
to increase the distributions with respect to Common Shares, as it has done in
the past, will be limited to management's ability to increase funds from
operations, and thereby cash available for distributions, from the existing
Properties in the Company's portfolio at such time.

     Bond Compliance Requirements. Certain of the Company's Properties are
subject to restrictive covenants or deed restrictions relating to current or
previous tax-exempt bond financing and owns the bonds collateralized by several
additional Properties. The Company has retained an independent outside
consultant to monitor compliance with the restrictive covenants and deed
restrictions that affect these Properties. The bond compliance requirements may
have the effect of limiting the Company's income from certain of these
Properties if the Company is required to lower its rental rates to attract low
or moderate income tenants, or eligible/qualified tenants.

CONTROL AND INFLUENCE BY SIGNIFICANT SHAREHOLDERS

     As of January 29, 1998, Mr. Zell, certain of the current holders (the "Zell
Holders") of certain OP Units ("Original OP Units") issued at the time of the
EQR IPO to certain affiliates of Mr. Zell which contributed 33 of the Properties
at the time of the EQR IPO (the "Zell Original Owners"), Equity Properties
Management Corp. ("EPMC") and other affiliates of Mr. Zell owned in the
aggregate approximately 4.5% of the Common Shares (assuming that all of the
partnership interests in the Operating Partnership are exchanged for Common
Shares), and certain entities controlled by Starwood Capital Partners L.P.
("Starwood") and its affiliates which contributed 23 of the Properties at the
time of the EQR IPO (the "Starwood Original Owners") owned in the aggregate
approximately 1.8% of the Common Shares (assuming that all of the OP Units are
exchanged for Common Shares). The Starwood Original Owners, together with the
Zell Original Owners, shall be referred to collectively as the "Original
Owners." As of January 28, 1998, the Company had options outstanding to purchase
approximately 5.6 million Common Shares (plus an additional 300,000 options to
purchase Common Shares which have been authorized by the Company for issuance
subject to shareholder approval) which it has granted to certain officers,



                                       5
<PAGE>   8

employees and trustees of the Company and consultants to the Company, some of
whom are affiliated with Mr. Zell, representing in the aggregate approximately
5.4% of the Common Shares outstanding (assuming that all such options are
exercised for Common Shares and all of the outstanding OP Units are exchanged
for Common Shares). Further, the consent of affiliates of Mr. Zell who are Zell
Holders and of the Starwood Original Owners is required for certain amendments
to the Operating Partnership's Fourth Amended and Restated ERP Operating Limited
Partnership Agreement of Limited Partnership (the "Partnership Agreement").
Accordingly, Mr. Zell and the Starwood Original Owners may continue to have
substantial influence over the Company, which influence might not be consistent
with the interests of other shareholders, and on the outcome of any matters
submitted to the Company's shareholders for approval. In addition, although
there is no current agreement, understanding or arrangement for these
shareholders to act together on any matter, these shareholders would be in a
position to exercise significant influence over the affairs of the Company if
they were to act together in the future.

POTENTIAL ENVIRONMENTAL LIABILITY AFFECTING THE COMPANY

     Under various federal, state and local environmental laws, ordinances and
regulations, an owner of real estate may be liable for the costs of removal or
remediation of certain hazardous or toxic substances on such property. These
laws often impose environmental liability without regard to whether the owner
knew of, or was responsible for, the presence of such hazardous or toxic
substances. The presence of such substances, or the failure properly to
remediate such substances, may adversely affect the owner's ability to sell or
rent the property or to borrow using the property as collateral. Persons who
arrange for the disposal or treatment of hazardous or toxic substances may also
be liable for the costs of removal or remediation of such substances at a
disposal or treatment facility, whether or not such facility is owned or
operated by such person. Certain laws impose liability for release of
asbestos-containing materials ("ACMs") into the air and third parties may seek
recovery from owners or operators of real properties for personal injury
associated with ACMs. In connection with the ownership (direct or indirect),
operation, management and development of real properties, the Company or the
Subsidiaries, as the case may be, may be considered an owner or operator of such
properties or as having arranged for the disposal or treatment of hazardous or
toxic substances and, therefore, potentially liable for removal or remediation
costs, as well as for certain other related costs, including governmental fines
and injuries to persons and property.

     All of the Properties have been the subject of a Phase I, and in certain
cases a supplemental, environmental assessment completed by qualified
independent environmental consultant companies. The most recent environmental
assessments for each of the Properties were conducted within the last five
years. Environmental assessments were obtained prior to the acquisition by the
Company of each of the Properties. These environmental assessments have not
revealed, nor is the Company aware of, any environmental liability that the
Company's management believes would have a material adverse effect on the
Company's business, results of operations, financial condition or liquidity.

     No assurance can be given that existing environmental assessments with
respect to any of the Properties reveal all environmental liabilities, that any
prior owner of a Property did not create any material environmental condition
not known to the Company, or that a material environmental condition does not
otherwise exist as to any one or more Properties.

GENERAL REAL ESTATE INVESTMENT CONSIDERATIONS; CHANGES IN LAWS

     General. Real property investments are subject to varying degrees of risk
and are relatively illiquid. Income from real property investments and the
Company's resulting ability to make expected distributions to shareholders may
be adversely affected by the general economic climate, local conditions such as
oversupply of apartment units or a reduction in demand for apartment units in
the area, the attractiveness of the Properties to tenants, zoning or other
regulatory restrictions, the ability of the Company to provide adequate
maintenance and insurance, and increased operating costs (including insurance
premiums and real estate taxes). The Company's income would also be adversely
affected if tenants were unable to pay rent or the Company were unable to rent
apartment units on favorable terms. If the Company were unable to promptly relet
units or renew the leases for a significant number of apartment units, or if the
rental rates upon such renewal or reletting were significantly lower than
expected rates, then the Company's funds from operations and ability to make
expected distributions to shareholders may be adversely affected. In addition,
certain expenditures associated with each equity investment (such as real estate
taxes and maintenance costs) generally are not reduced when circumstances cause
a reduction in income from the investment. Furthermore, real estate investments
are relatively illiquid and, therefore, will tend to limit the ability of the
Company to vary its portfolio promptly in response to changes in economic or
other conditions.

     Changes in Laws. Increases in real estate taxes, income taxes and service
or other taxes generally are not passed through to tenants under existing leases
and may adversely affect the Company's funds from operations and its ability to
make distributions to 


                                       6
<PAGE>   9

shareholders. Similarly, changes in laws increasing the potential liability for
environmental conditions existing on properties or increasing the restrictions
on discharges or other conditions may result in significant unanticipated
expenditures, which would adversely affect the Company's funds from operations
and its ability to make distributions to shareholders.

OWNERSHIP LIMIT AND LIMITS ON CHANGES IN CONTROL

     5% Ownership Limit; Inapplicability to Mr. Zell and Others. In order to
maintain its qualification as a REIT under the Code, not more than 50% of the
value of the outstanding shares of beneficial interest of the Company may be
owned, directly or indirectly, by five or fewer individuals (as defined in the
Code to include certain entities). Certain beneficial owners of the Zell Holders
(i.e., beneficiaries of trusts established for the benefit of Mr. Zell and his
family and trusts established for the benefit of the family of Mr. Robert Lurie,
a deceased partner of Mr. Zell (the "Lurie Family Trusts")), EPMC, the Starwood
Original Owners and Mr. Henry H. Goldberg, a Trustee of the Company (through
their potential ownership of Common Shares) together constitute five individuals
for purposes of this test and, under the Internal Revenue Service's (the
"Service") rules applicable to determining percentages of ownership, will be
deemed to own approximately 4.9% of the value of the outstanding shares of
beneficial interest of the Company. Due to such concentration of ownership of
the Company, ownership of more than 5% of the lesser of the number or value of
the outstanding shares of beneficial interest of the Company by any single
shareholder has been restricted, with certain exceptions, for the purpose of
maintaining the Company's qualification as a REIT under the Code. Such
restrictions in the Company's Declaration of Trust do not apply to the ownership
of the 5,504,860 Common Shares subject to acquisition by the holders of Original
OP Units and EPMC through the exchange of Original OP Units. Additionally, the
Company's Declaration of Trust allows certain transfers of such Common Shares
without the transferees being subject to the 5% ownership limit, provided such
transfers do not result in an increased concentration in the ownership of the
Company. The Company's Board of Trustees, upon receipt of a ruling from the
Service, an opinion of counsel or other evidence satisfactory to the Board of
Trustees and upon such other conditions as the Board of Trustees may direct, may
also exempt a proposed transferee from this restriction. See "Description of
Shares of Beneficial Interest--Common Shares--Restrictions on Transfer."

     The 5% ownership limit, as well as the ability of the Company to issue
additional Common Shares or other shares of beneficial interest (which may have
rights and preferences senior to the Common Shares), may discourage a change of
control of the Company and may also (i) deter tender offers for the Common
Shares, which offers may be advantageous to shareholders, and (ii) limit the
opportunity for shareholders to receive a premium for their Common Shares that
might otherwise exist if an investor were attempting to assemble a block of
Common Shares in excess of 5% of the outstanding shares of beneficial interest
of the Company or otherwise effect a change of control of the Company.

     Possible Adverse Consequences of Ownership Limit. To maintain its
qualification as a REIT for federal income tax purposes, not more than 50% in
value of the outstanding shares of beneficial interest of the Company may be
owned, directly or indirectly, by five or fewer individuals (as defined in the
Code, to include certain entities). See "Federal Income Tax
Considerations--Taxation of the Company--Share Ownership Test." Certain
beneficial owners of the Zell Holders (i.e., beneficiaries of trusts established
for benefit of Mr. Zell and his family and the family of Mr. Robert Lurie, a
deceased partner of Mr. Zell) and EPMC, together with the Starwood Original
Owners and Mr. Goldberg (through their potential ownership of Common Shares)
together constitute five individuals for purposes of this test and, under the
Service's rules applicable to determining percentages of ownership, are deemed
to own approximately 4.9% of the value of the outstanding shares of beneficial
interest of the Company. To facilitate maintenance of its qualification as a
REIT for federal income tax purposes, the Company generally will prohibit
ownership, directly or by virtue of the attribution provisions of the Code, by
any single shareholder of more than 5% of the issued and outstanding Common
Shares and generally will prohibit ownership, directly or by virtue of the
attribution provisions of the Code, by any single shareholder of more than 5% of
the issued and outstanding shares of any class or series of the Company's
Preferred Shares (collectively, the "Ownership Limit"). The Board of Trustees
may, in its reasonable discretion, waive or modify the Ownership Limit with
respect to one or more persons who would not be treated as "individuals" for
purposes of the Code if it is satisfied, based upon information required to be
provided by the party seeking the waiver, that ownership in excess of this limit
will not cause a person who is an individual to be treated as owning Common
Shares or Preferred Shares in excess of the Ownership Limit, applying the
applicable constructive ownership rules, and will not otherwise jeopardize the
Company's status as a REIT for federal income tax purposes. The Company's
Declaration of Trust also exempts from the Ownership Limit certain of the
beneficial owners of the Original Owners and EPMC, who would exceed the
Ownership Limit as a result of the exchange of the OP Units for Common Shares,
which OP Units were received by them at the time of the formation of EQR. Absent
any such exemption or waiver, Common Shares or Preferred Shares acquired or held
in violation of the Ownership Limit will be transferred to a trust for the
benefit of a designated charitable beneficiary, with the person who acquired
such Common Shares and/or Preferred Shares in violation of the Ownership Limit
not entitled to receive any distributions thereon, to vote such Common Shares or
Preferred Shares, or to receive any proceeds from the subsequent sale thereof in
excess of the lesser of the price paid therefore or the amount realized from



                                       7
<PAGE>   10

such sale. A transfer of Common Shares and/or Preferred Shares to a person who,
as a result of the transfer, violates the Ownership Limit may be void under
certain circumstances. See "Description of Shares of Beneficial
Interest--Restrictions on Ownership and Transfer." The Ownership Limit may have
the effect of delaying, deferring or preventing a change in control and,
therefore, could adversely affect the shareholder's ability to realize a premium
over the then-prevailing market price for the Common Shares in connection with
such transaction.

     Staggered Board. The Board of Trustees of the Company has been divided into
three classes of trustees. As the term of each class expires, trustees for that
class will be elected for a three-year term and the trustees in the other two
classes will continue in office. The staggered terms for trustees may impede the
shareholders' ability to change control of the Company even if a change in
control were in the shareholders' interest.

     Preferred Shares. The Company's Declaration of Trust authorizes the Board
of Trustees to issue up to 100,000,000 preferred shares of beneficial interest,
$.01 par value per share ("Preferred Shares"), and to establish the preferences
and rights (including the right to vote and the right to convert into Common
Shares) of any Preferred Shares issued. The power to issue Preferred Shares
could have the effect of delaying or preventing a change in control of the
Company even if a change in control were in the shareholders' interest. As of
January 29, 1998, 15,343,500 Preferred Shares were issued and outstanding.

CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT

     Taxation as a Corporation. The Company believes that it has qualified and
will continue to qualify as a REIT under the Code, commencing with its taxable
year ended December 31, 1992. However, no assurance can be given that the
Company was organized and has been operated and will be able to operate in a
manner so as to qualify or remain so qualified. Qualification as a REIT involves
the satisfaction of numerous requirements (some on an annual and quarterly
basis) established under highly technical and complex Code provisions for which
there are only limited judicial or administrative interpretations, and involves
the determination of various factual matters and circumstances not entirely
within the Company's control.

     If the Company were to fail to qualify as a REIT in any taxable year, the
Company would be subject to federal income tax (including any applicable
alternative minimum tax) on its taxable income at corporate rates. Moreover,
unless entitled to relief under certain statutory provisions, the Company also
would be disqualified from treatment as a REIT for the four taxable years
following the year during which qualification is lost. This treatment would
reduce the net earnings of the Company available for investment or distribution
to shareholders because of the additional tax liability to the Company for the
years involved. In addition, distributions to shareholders would no longer be
required to be made. See "Federal Income Tax Considerations."

     Other Tax Liabilities. Even if the Company qualifies as a REIT, it will be
subject to certain federal, state and local taxes on its income and property.
See "Federal Income Tax Considerations--Other Tax Considerations--State and
Local Taxes." In addition, the Company's management operations, which are
conducted through Equity Residential Properties Management Limited Partnership
and Equity Residential Properties Management Limited Partnership II
(collectively, the "Management Partnerships") generally will be subject to
federal income tax at regular corporate rates. See "Federal Income Tax
Considerations--Other Tax Considerations."

DEPENDENCE ON KEY PERSONNEL

     The Company is dependent on the efforts of its executive officers. While
the Company believes that it could find replacements for these key personnel,
the loss of their services could have a temporary adverse effect on the
operations of the Company. None of these officers has entered into employment
agreements with the Company.



                                       8

DISTRIBUTION REQUIREMENTS POTENTIALLY INCREASING INDEBTEDNESS OF THE COMPANY

     The Company may be required from time to time, under certain circumstances,
to accrue as income for tax purposes interest and rent earned but not yet
received. In such event, or upon the repayment by the Company or its
Subsidiaries of principal on debt, the Company could have taxable income without
sufficient cash to enable the Company to meet the distribution requirements of a
REIT. Accordingly, the Company could be required to borrow funds or liquidate
investments on adverse terms in order to meet such distribution requirements.
See "Federal Income Tax Considerations--Taxation of the Company--Annual
Distribution Requirements."

EXEMPTIONS FOR MR. ZELL AND OTHERS FROM MARYLAND BUSINESS COMBINATION LAW 
WHICH TEND TO INHIBIT TAKEOVERS

     Under the Maryland General Corporation Law, as amended ("MGCL"), certain
"business combinations" (including a merger, consolidation, share exchange or,
in certain circumstances, an asset transfer or issuance or reclassification of
equity securities) between a Maryland real estate investment trust and any
person who beneficially owns 10% or more of the voting power of the trust's
shares of beneficial interest or an affiliate of the trust who, at any time
within the two-year period prior to the date in question, was the beneficial
owner of 10% or more of the voting power of the trust's shares of beneficial
interest (an "Interested Shareholder"), or an affiliate of such Interested
Shareholder, are prohibited for five years after the most recent date on which
the Interested Shareholder becomes an Interested Shareholder. Thereafter, any
such business combination must be recommended by the board of trustees of such
trust and approved by the affirmative vote of at least (a) 80% of the votes
entitled to be cast by holders of outstanding voting shares of beneficial
interest of the trust and (b) two-thirds of the votes entitled to be cast by
holders of voting shares of beneficial interest of the trust other than shares
held by the Interested Shareholder with whom (or with whose affiliate) the
business combination is to be effected, (unless, among other conditions, the
holders of the common shares of the trust receive a minimum price (as defined in
the MGCL) for their shares and the consideration is received in cash or in the
same form as previously paid by the Interested Shareholder for its common
shares. As permitted by the MGCL, the Company has exempted any business
combination involving Mr. Zell, the Zell Original Owners, EPMC and their
respective affiliates and associates, present or future, or any other person
acting in concert or as a group with any of the foregoing persons and,
consequently, the five-year prohibition and the super-majority vote requirements
will not apply to a business combination between any of them and the Company. As
a result, Mr. Zell, the Zell Original Owners, EPMC, any present or future
affiliate or associate of theirs or any other person acting in concert or as a
group with any of the foregoing persons may be able to enter into business
combinations with the Company, which may not be in the best interest of the
shareholders, without compliance by the Company with the super-majority vote
requirements and other provisions of the MGCL.

                                 USE OF PROCEEDS

     Unless otherwise indicated in the accompanying Prospectus Supplement, the
Company will contribute or otherwise transfer the net proceeds of any sale of
Securities to the Operating Partnership in exchange for additional partnership
interests in the Operating Partnership, the economic terms of which will be
substantially identical to the Securities sold. The Operating Partnership will
use such net proceeds for general business purposes including, without
limitation, the repayment of certain outstanding debt and the acquisition of
multifamily properties.

                  DESCRIPTION OF SHARES OF BENEFICIAL INTEREST

     The summary of the terms of the shares of beneficial interest of the
Company set forth below does not purport to be complete and is subject to and
qualified in its entirety by reference to the Declaration of Trust, as amended
and/or restated from time to time, and the Bylaws, as amended and/or restated
from time to time, of the Company, each of which is incorporated herein by
reference.

     The Declaration of Trust of the Company provides that the Company may issue
up to 300,000,000 shares of beneficial interest, consisting of 200,000,000
Common Shares and 100,000,000 Preferred Shares. As of January 29, 1998,
93,396,665 Common Shares and 15,343,500 Preferred Shares were issued and
outstanding. In addition, as of January 29, 1998, 9,592,090 Common Shares were
issuable upon exchange of OP Units currently held by the Zell Holders, the
Starwood Original Owners, EPMC and holders who were issued OP Units in exchange
for the contribution of certain of the Properties to the Operating Partnership
subsequent to the EQR IPO. The OP Units are exchangeable on a one-for-one basis
for Common Shares or, at the Company's option, cash.

     Both the Maryland REIT law and the Company's Declaration of Trust provide
that no shareholder of the Company will be liable for any debt or obligation of
the Company solely as a result of his status as a shareholder of the Company.
The Company's Bylaws further 


                                       9
<PAGE>   12

provide that the Company shall indemnify each shareholder against any claim or
liability to which the shareholder may become subject by reason of his being or
having been a shareholder and that the Company shall reimburse each shareholder
for all reasonable expenses incurred by him in connection with any such claim or
liability. However, with respect to tort claims, contractual claims where
shareholder liability is not so negated, claims for taxes and certain statutory
liability, the shareholders may, in some jurisdictions, be personally liable to
the extent that such claims are not satisfied by the Company. Inasmuch as the
Company carries public liability insurance which it considers adequate, any risk
of personal liability to shareholders is limited to situations in which the
Company's assets plus its insurance coverage would be insufficient to satisfy
the claims against the Company and its shareholders.

PREFERRED SHARES

     The following description of the Preferred Shares sets forth certain
general terms and provisions of the Preferred Shares to which any Prospectus
Supplement may relate.

     The Board of Trustees is empowered by the Company's Declaration of Trust to
designate and issue from time to time one or more series of Preferred Shares
without shareholder approval. The Board of Trustees may determine the relative
rights, preferences and privileges of each series of Preferred Shares so issued.
Because the Board of Trustees has the power to establish the preferences and
rights of each series of Preferred Shares, it may afford the holders of any
series of Preferred Shares preferences, powers and rights, voting or otherwise,
senior to the rights of holders of Common Shares. The Preferred Shares will,
when issued, be fully paid and nonassessable.

     The Company currently has outstanding 6,120,000 Series A Preferred Shares
(liquidation preference $25.00 per share), 5,000,000 depositary shares
representing a 1/10 fractional interest in 500,000 Series B Preferred Shares
(liquidation preference $250.00 per share, equivalent to $25.00 per depositary
share), 4,600,000 depositary shares representing a 1/10 fractional interest in
460,000 Series C Preferred Shares (liquidation preference $250.00 per share,
equivalent to $25.00 per depositary share), 7,000,000 depositary shares
representing a 1/10 fractional interest in 700,000 Series D Preferred Shares
(liquidation preference $250.00 per share, equivalent to $25.00 per depositary
share), 3,998,500 Series E Preferred Shares (liquidation preference $25.00 per
share), 2,300,000 Series F Preferred Shares (liquidation preference $25.00 per
share) and 12,650,000 depositary shares representing a 1/10 fractional interest
in 1,265,000 Series G Preferred Shares (liquidation preference $250.00 per
share, equivalent to $25.00 per depositary share) that are listed on the New
York Stock Exchange under the symbols "EQR-PrA," "EQR-PrB," "EQR-PrC,"
"EQR-PrD," "EQR-PrE," "EQR-PrF," and "EQR-PrG,"respectively. Distributions on
the Series A Preferred Shares, the Series B Preferred Shares, the Series C
Preferred Shares, the Series D Preferred Shares, the Series F Preferred Shares
and the Series G Preferred Shares are cumulative from the date of original issue
and payable quarterly on or about the fifteenth day of January, April, July and
October of each year, at the rate of 9 3/8%, 9 1/8%, 9 1/8%, 8.60% , 9.65% and 7
1/4%, respectively, of the liquidation preference per annum of such shares.
Distributions on the Series E Preferred Shares are cumulative from the date of
original issue and payable quarterly on the first day of January, April, July
and October of each year, at the rate of 7.0% of the liquidation preference per
annum of such shares.

     The Series A Preferred Shares are not redeemable prior to June 1, 2000. On
or after June 1, 2000, the Series A Preferred Shares may be redeemed for cash at
the option of the Company in whole or in part, at a redemption price of $25.00
per share, plus accrued and unpaid distributions, if any, thereon. The Series B
Preferred Shares are not redeemable prior to October 15, 2005. On or after
October 15, 2005, the Series B Preferred Shares may be redeemed for cash at the
option of the Company in whole or in part, at a redemption price of $250.00 per
share (equivalent to $25.00 per depositary share), plus accrued and unpaid
distributions, if any, thereon. The Series C Preferred Shares are not redeemable
prior to September 9, 2006. On or after September 9, 2006, the Series C
Preferred Shares may be redeemed for a cash at the option of the Company in
whole or in part, at a redemption price of $250.00 per share (equivalent to
$25.00 per depositary share), plus accrued and unpaid distributions, if any,
thereon. The Series D Preferred Shares are not redeemable prior to July 15,
2007. On or after July 15, 2007, the Series D Preferred Shares may be redeemed
for cash at the option of the Company in whole or in part, at a redemption price
of $250.00 per share (equivalent to $25.00 per depositary share), plus
accumulated unpaid distributions, if any, thereon. Each Series E Preferred Share
is convertible at the option of the holder thereof at any time into Common
Shares of the Company, at a conversion price of $44.93 per Common Share
(equivalent to a conversion rate of approximately .5564 Common Share for each
Series E Preferred Share), subject to adjustments under certain conditions. The
Series E Preferred Shares are not redeemable prior to November 1, 1998. On or
after November 1, 1998, the Series E Preferred Shares may be redeemed for cash
at the option of the Company in whole or in part, initially at $25.875 per share
and thereafter at prices declining to $25.00 per share on and after November 1,
2003, plus in each case accrued and unpaid distributions, if any, to the
redemption date. The Series F Preferred Shares are not redeemable prior to
August 24, 2000. On or after August 24, 2000, the Series F Preferred Shares may
be redeemed for cash at the option of the Company in whole or in part, at a
redemption price of $25.00 per share, plus accrued and unpaid distributions, if
any, thereon. Depositary shares representing the Series G Preferred Shares are
convertible at any time at the option of the holders into Common Shares at a
conversion 




                                       10
<PAGE>   13

price of $58.58 per Common Share (equivalent to a conversion rate of .4268
Common Share for each depositary share), subject to adjustment in certain
circumstances. The depositary shares representing the Series G Preferred Shares
are not redeemable prior to September 15, 2002. On and after September 15, 2002,
the Series G Preferred Shares may be redeemed at the option of the Company,
initially at $25.90625 per depositary share and thereafter at prices declining
to $25.00 per depositary share on or after September 15, 2007. With the
exception of the Series G Preferred Shares, the redemption price of such
Preferred Shares (other than the portion thereof consisting of accrued and
unpaid distributions) is payable solely out of the sale proceeds of other shares
of beneficial interest of the Company which may include other series of
Preferred Shares. The Series A Preferred Shares, the Series B Preferred Shares,
the Series C Preferred Shares, the Series D Preferred Shares, the Series E
Preferred Shares, the Series F Preferred Shares and the Series G Preferred
Shares have no stated maturity and are not subject to any sinking fund or
mandatory redemption and, with the exception of the Series E Preferred Shares
and the Series G Preferred Shares, are not convertible into any other securities
of the Company. However, the Company may redeem Series A Preferred Shares,
Series B Preferred Shares, Series C Preferred Shares, the Series D Preferred
Shares, the Series E Preferred Shares, the Series F Preferred Shares or the
Series G Preferred Shares in certain circumstances relating to maintenance of
its status as a REIT for federal income tax purposes. See "-Redemption" and
"-Restrictions on Transfer" below. The other terms of the Preferred Shares are
described generally below.

     The Prospectus Supplement relating to any Preferred Shares offered thereby
will contain the specific terms thereof, including, without limitation:

     (1)  The title and stated value of such Preferred Shares;

     (2)  The number of such Preferred Shares offered, the liquidation
          preference per share and the offering price of such Preferred Shares;

          Shares will be convertible into Common Shares of the Company,
          including the conversion price (or manner of calculation thereof);

     (10) Whether interests in such Preferred Shares will be represented by

          restrictions of such Preferred Shares;

     (12) A discussion of all material federal income tax considerations, if

          winding up of the affairs of the Company; and

     (15) Any limitations on direct or beneficial ownership and restrictions on
          transfer, in each case as may be appropriate to preserve the status of
          the Company as a REIT.



                                       11

     Rank. Unless otherwise specified in the applicable Prospectus Supplement,
the Preferred Shares will, with respect to distribution rights and rights upon
liquidation, dissolution or winding up of the Company, rank (i) senior to all
classes or series of Common Shares of the Company, and to all equity securities
ranking junior to such Preferred Shares; (ii) on a parity with all equity
securities issued by the Company the terms of which specifically provide that
such equity securities rank on a parity with the Preferred Shares; and (iii)
junior to all equity securities issued by the Company the terms of which
specifically provide that such equity securities rank senior to the Preferred
Shares. The term "equity securities" does not include convertible debt
securities.

     Distributions. Holders of the Preferred Shares of each series will be
entitled to receive, when, as and if declared by the Board of Trustees of the
Company, out of assets of the Company legally available for payment, cash
distributions (or distributions in kind or in other property if expressly
permitted and described in the applicable Prospectus Supplement) at such rates
and on such dates as will be set forth in the applicable Prospectus Supplement.
Each such distribution shall be payable to holders of record as they appear on
the share transfer books of the Company on such record dates as shall be fixed
by the Board of Trustees of the Company.

     Distributions on any series of Preferred Shares may be cumulative or
non-cumulative, as provided in the applicable Prospectus Supplement.
Distributions, if cumulative, will be cumulative from and after the date set
forth in the applicable Prospectus Supplement. If the Board of Trustees of the
Company fails to declare a distribution payable on a distribution payment date
on any series of the Preferred Shares for which distributions are
non-cumulative, then the holders of such series of the Preferred Shares will
have no right to receive a distribution in respect of the distribution period
ending on such distribution payment date, and the Company will have no
obligation to pay the distribution accrued for such period, whether or not
distributions on such series are declared payable on any future distribution
payment date.

     Unless otherwise specified in the Prospectus Supplement, if any Preferred
Shares of any series are outstanding, no full distributions shall be declared or
paid or set apart for payment on any shares of beneficial interest of the
Company of any other series ranking, as to distributions, on a parity with or
junior to the Preferred Shares of such series for any period unless (i) if such
series of Preferred Shares has a cumulative distribution, full cumulative
distributions 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
Preferred Shares of such series for all past distribution periods and the then
current distribution period or (ii) if such series of Preferred Shares does not
have a cumulative distribution, full distributions for the then current
distribution period 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 Preferred Shares of such series. When distributions are not paid in full
(or a sum sufficient for such full payment is not so set apart) upon Preferred
Shares of any series and the shares of any other series of Preferred Shares
ranking on a parity as to distributions with the Preferred Shares of such
series, all distributions declared upon Preferred Shares of such series and any
other series of Preferred Shares ranking on a parity as to distributions with
such Preferred Shares shall be declared pro rata so that the amount of
distributions declared per share of Preferred Shares of such series and such
other series of Preferred Shares shall in all cases bear to each other the same
ratio that accrued distributions per share on the Preferred Shares of such
series (which shall not include any accumulation in respect of unpaid
distributions for prior distribution periods if such Preferred Shares do not
have a cumulative distribution) and such other series of Preferred Shares bear
to each other. No interest, or sum of money in lieu of interest, shall be
payable in respect of any distribution payment or payments on Preferred Shares
of such series which may be in arrears.

     Except as provided in the immediately preceding paragraph, unless (i) if
such series of Preferred Shares has a cumulative distribution, full cumulative
distributions on the Preferred Shares of such series 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 distribution periods and the
then current distribution period, and (ii) if such series of Preferred Shares
does not have a cumulative distribution, full distributions on the Preferred
Shares of such series have been or contemporaneously are declared and paid or
declared and a sum sufficient for the payment thereof set apart for payment, for
the then current distribution period, no distributions (other than in Common
Shares or other shares of beneficial interest ranking junior to the Preferred
Shares of such series as to distributions and upon liquidation) shall be
declared or paid or set aside for payment or other distribution upon the Common
Shares, or any other shares of beneficial interest of the Company ranking junior
to or on a parity with the Preferred Shares of such series as to distributions
or upon liquidation, nor shall any Common Shares, or any other shares of
beneficial interest of the Company ranking junior to or on a parity with the
Preferred Shares of such series as to distributions or upon liquidation be
redeemed, purchased or otherwise acquired for any consideration (or any moneys
be paid to or made available for a sinking fund for the redemption of any such
shares) by the Company (except by conversion into or exchange for other shares
of beneficial interest of the Company ranking junior to the Preferred Shares of
such series as to distributions and upon liquidation).




                                       12
<PAGE>   15

     If, for any taxable year, the Company elects to designate as "capital gain
dividends" (as defined in Section 857 of the Code) any portion (the "Capital
Gains Amount") of the dividends (within the meaning of the Code) paid or made
available for the year to holders of all classes of shares of beneficial
interest (the "Total Dividends"), then the portion of the Capital Gains Amount
that will be allocable to the holders of Preferred Shares will be the Capital
Gains Amount multiplied by a fraction, the numerator of which will be the total
dividends (within the meaning of the Code) paid or made available to the holders
of the Preferred Shares for the year and the denominator of which shall be the
Total Dividends.

     Redemption. If so provided in the applicable Prospectus Supplement, the
Preferred Shares will be subject to mandatory redemption or redemption at the
option of the Company, in whole or in part, in each case upon the terms, at the
times and at the redemption prices set forth in such Prospectus Supplement.

     The Prospectus Supplement relating to a series of Preferred Shares that is
subject to mandatory redemption will specify the number of such Preferred Shares
that shall be redeemed by the Company in each year commencing after a date to be
specified, at a redemption price per share to be specified, together with an
amount equal to all accrued and unpaid distributions thereon (which shall not,
if such Preferred Shares do not have a cumulative distribution, include any
accumulation in respect of unpaid distributions for prior distribution periods)
to the date of redemption. The redemption price may be payable in cash or other
property, as specified in the applicable Prospectus Supplement. If the
redemption price for Preferred Shares of any series is payable only from the net
proceeds of the issuance of shares of beneficial interest of the Company, the
terms of such Preferred Shares may provide that, if no such shares of beneficial
interest shall have been issued or to the extent the net proceeds from any
issuance are insufficient to pay in full the aggregate redemption price then
due, such Preferred Shares shall automatically and mandatorily be converted into
the applicable shares of beneficial interest of the Company pursuant to
conversion provisions specified in the applicable Prospectus Supplement.

     Notwithstanding the foregoing, unless (i) if such series of Preferred
Shares has a cumulative distribution, full cumulative distributions on all
Preferred Shares of any series 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 distribution periods and the current distribution period
and (ii) if such series of Preferred Shares does not have a cumulative
distribution, full distributions on the Preferred Shares of any series have been
or contemporaneously are declared and paid or declared and a sum sufficient for
the payment thereof set apart for payment for the then current distribution
period, no Preferred Shares of any series shall be redeemed unless all
outstanding Preferred Shares of such series are simultaneously redeemed;
provided, however, that the foregoing shall not prevent the purchase or
acquisition of Preferred Shares of such series to preserve the REIT status of
the Company or pursuant to a purchase or exchange offer made on the same terms
to holders of all outstanding Preferred Shares of such series. In addition,
unless (i) if such series of Preferred Shares has a cumulative distribution,
full cumulative distributions on all outstanding shares of any series of
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 past distributions periods and the then current distribution period, and
(ii) if such series of Preferred Shares does not have a cumulative distribution,
full distributions on the Preferred Shares of any series have been or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof set apart for payment for the then current distribution period,
the Company shall not purchase or otherwise acquire directly or indirectly any
Preferred Shares of such series (except by conversion into or exchange for
shares of beneficial interest of the Company ranking junior to the Preferred
Shares of such series as to distributions and upon liquidation); provided,
however, that the foregoing shall not prevent the purchase or acquisition of
Preferred Shares of such series to assist in maintaining the REIT status of the
Company or pursuant to a purchase or exchange offer made on the same terms to
holders of all outstanding Preferred Shares of such series.

     If fewer than all of the outstanding Preferred Shares of any series are to
be redeemed, the number of shares to be redeemed will be determined by the
Company and such shares may be redeemed pro rata from the holders of record of
such shares in proportion to the number of such shares held or for which
redemption is requested by such holder (with adjustments to avoid redemption of
fractional shares) or by lot in a manner determined by the Company.

     Notice of redemption will be mailed at least 30 days but not more than 60
days before the redemption date to each holder of record of Preferred Shares of
any series to be redeemed at the address shown on the share transfer books of
the Company. Each notice shall state: (i) the redemption date; (ii) the number
and series of Preferred Shares to be redeemed; (iii) the place or places where
certificates for such Preferred Shares are to be surrendered for payment of the
redemption price; (iv) that distributions on the shares to be redeemed will
cease to accrue on such redemption date; and (v) the date upon which the
holder's conversion rights, if any, as to such shares shall terminate. If fewer
than all of the Preferred Shares of any series are to be redeemed, the notice
mailed to each such holder thereof shall also specify the number of Preferred
Shares to be redeemed from each such holder. If notice of redemption of any
Preferred Shares has been given and if the funds necessary for such redemption
have been set aside by the Company in trust for the benefit of the holders of
any Preferred Shares 




                                       13
<PAGE>   16

so called for redemption, then from and after the redemption date distributions
will cease to accrue on such Preferred Shares, and all rights of the holders of
such shares will terminate, except the right to receive the redemption price.

     Liquidation Preference. Upon any voluntary or involuntary liquidation,
dissolution or winding up of the affairs of the Company, then, before any
distribution or payment shall be made to the holders of any Common Shares or any
other class or series of shares of beneficial interest of the Company ranking
junior to the Preferred Shares in the distribution of assets upon any
liquidation, dissolution or winding up of the Company, the holders of each
series of Preferred Shares shall be entitled to receive out of assets of the
Company legally available for distribution to shareholders liquidating
distributions in the amount of the liquidation preference per share (set forth
in the applicable Prospectus Supplement), plus an amount equal to all
distributions accrued and unpaid thereon (which shall not include any
accumulation in respect of unpaid distributions for prior distribution periods
if such Preferred Shares do not have a cumulative distribution). After payment
of the full amount of the liquidating distributions to which they are entitled,
the holders of Preferred Shares will have no right or claim to any of the
remaining assets of the Company. In the event that, upon any such voluntary or
involuntary liquidation, dissolution or winding up, the available assets of the
Company are insufficient to pay the amount of the liquidating distributions on
all outstanding Preferred Shares and the corresponding amounts payable on all
shares of other classes or series of shares beneficial interest of the Company
ranking on a parity with the Preferred Shares in the distribution of assets,
then the holders of the Preferred Shares and all other such classes or series of
shares of beneficial interest shall share ratably in any such distribution of
assets in proportion to the full liquidating distributions to which they would
otherwise be respectively entitled.

     If liquidating distributions shall have been made in full to all holders of
Preferred Shares, the remaining assets of the Company shall be distributed among
the holders of any other classes or series of shares of beneficial interest
ranking junior to the Preferred Shares upon liquidation, dissolution or winding
up, according to their respective rights and preferences and in each case
according to their respective number of shares. For such purposes, the
consolidation or merger of the Company with or into any other corporation, trust
or entity, or the sale, lease or conveyance of all or substantially all of the
property or business of the Company, shall not be deemed to constitute a
liquidation, dissolution or winding up of the Company.

     Voting Rights. Holders of Preferred Shares will not have any voting rights,
except as set forth below or as otherwise from time to time required by law or
as indicated in the applicable Prospectus Supplement.

     Whenever distributions on any Preferred Shares shall be in arrears for six
or more quarterly periods, the holders of such Preferred Shares (voting
separately as a class with all other series of Preferred Shares upon which like
voting rights have been conferred and are exercisable) will be entitled to vote
for the election of two additional Trustees of the Company at a special meeting
called by the holders of record of at least ten percent (10%) of any series of
Preferred Shares so in arrears (unless such request is received less than 90
days before the date fixed for the next annual or special meeting of the
shareholders) or at the next annual meeting of shareholders, and at each
subsequent annual meeting until (i) if such series of Preferred Shares has a
cumulative distribution, all distributions accumulated on such series of
Preferred Shares for the past distribution periods and the then current
distribution period shall have been fully paid or declared and a sum sufficient
for the payment thereof set aside for payment or (ii) if such series of
Preferred Shares do not have a cumulative distribution, four consecutive
quarterly distributions shall have been fully paid or declared and a sum
sufficient for the payment thereof set aside for payment. In such case, the
entire Board of Trustees of the Company will be increased by two Trustees.

     Unless provided otherwise for any series of Preferred Shares, so long as
any Preferred Shares remain outstanding, the Company will not, without the
affirmative vote or consent of the holders of at least two-thirds of each series
of Preferred Shares outstanding at the time, given in person or by proxy, either
in writing or at a meeting (such series voting separately as a class), (i)
authorize or create, or increase the authorized or issued amount of, any class
or series of shares of beneficial interest ranking prior to such series of
Preferred Shares with respect to the payment of distributions or the
distribution of assets upon liquidation, dissolution or winding up or reclassify
any authorized shares of beneficial interest of the Company into such shares, or
create, authorize or issue any obligation or security convertible into or
evidencing the right to purchase any such shares; or (ii) amend, alter or repeal
the provisions of the Company's Declaration of Trust or the Articles
Supplementary for such series of Preferred Shares, whether by merger,
consolidation or otherwise (an "Event"), so as to materially and adversely
affect any right, preference, privilege or voting power of such series of
Preferred Shares or the holders thereof; provided, however, with respect to the
occurrence of any of the Events set forth in (ii) above, so long as the
Preferred Shares remain outstanding with the terms thereof materially unchanged,
taking into account that upon the occurrence of an Event, the Company may not be
the surviving entity, the occurrence of any such Event shall not be deemed to
materially and adversely affect such rights, preferences, privileges or voting
power of holders of Preferred Shares and provided further that (x) any increase
in the amount of the authorized Preferred Shares or the creation or issuance of
any other series of Preferred Shares, or (y) any increase in the amount of
authorized shares of such series or any other series of Preferred Shares, in
each case ranking on a parity with or junior to the Preferred Shares of such
series 


                                       14
<PAGE>   17

with respect to payment of distributions or the distribution of assets upon
liquidation, dissolution or winding up, shall not be deemed to materially and
adversely affect such rights, preferences, privileges or voting powers.

     The foregoing voting provisions will 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 Preferred Shares of such series shall have been
redeemed or called for redemption and sufficient funds shall have been deposited
in trust to effect such redemption.

     Conversion Rights. The terms and conditions, if any, upon which any series
of Preferred Shares is convertible into Common Shares will be set forth in the
applicable Prospectus Supplement relating thereto. Such terms will include the
number of Common Shares into which the Preferred Shares are convertible, the
conversion price (or manner of calculation thereof), the conversion period,
provisions as to whether conversion will be at the option of the holders of the
Preferred Shares or the Company, the events requiring an adjustment of the
conversion price and provisions affecting conversion in the event of the
redemption of such series of Preferred Shares.

     Registrar and Transfer Agent. The registrar and transfer agent for the
Preferred Shares will be set forth in the applicable Prospectus Supplement.

COMMON SHARES

     All Common Shares offered hereby will be duly authorized, fully paid and
nonassessable. Subject to the preferential rights of any other shares of
beneficial interest and to the provisions of the Company's Declaration of Trust
regarding excess shares (as defined herein), holders of Common Shares are
entitled to receive distributions if, as and when authorized and declared by the
Board of Trustees out of assets legally available therefor and to share ratably
in the assets of the Company legally available for distribution to its
shareholders in the event of its liquidation, dissolution or winding-up after
payment of, or adequate provision for, all known debts and liabilities of the
Company. The Company currently pays regular quarterly distributions.

     Subject to the provisions of the Company's Declaration of Trust regarding
excess shares, each outstanding Common Share entitles the holder to one vote on
all matters submitted to a vote of shareholders, including the election of
Trustees, and, except as otherwise required by law or except as provided with
respect to any other class or series of shares of beneficial interest, the
holders of such Common Shares will possess the exclusive voting power. There is
no cumulative voting in the election of Trustees, which means that the holders
of a majority of the outstanding Common Shares can elect all of the Trustees
then standing for election and the holders of the remaining shares of beneficial
interest, if any, will not be able to elect any Trustees.

     Holders of Common Shares have no conversion, sinking fund, redemption or
preemptive rights to subscribe for any securities of the Company. Subject to the
provisions of the Company's Declaration of Trust regarding excess shares, Common
Shares have equal distribution, liquidation and other rights, and have no
preference, exchange or, except as expressly required by the Maryland REIT law,
appraisal rights.

     Pursuant to the Maryland REIT law, a REIT generally cannot dissolve, amend
its declaration of trust or merge, unless approved by the affirmative vote or
written consent of shareholders holding at least two-thirds of the shares
entitled to vote 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 REIT's declaration of trust. The Company's Declaration of Trust provides
that a dissolution or merger, and amendments to the Declaration of Trust in
connection with such transactions, may be approved by the affirmative vote of
the holders of not less than a majority of the shares then outstanding and
entitled to vote thereon. A declaration of trust may permit the trustees by a
two-thirds vote to amend the declaration of trust from time to time to qualify
as a REIT under the Code or the Maryland REIT law without the affirmative vote
or written consent of the shareholders. The Company's Declaration of Trust
permits such action by the Board of Trustees.

     The registrar and transfer agent for the Common Shares is Boston EquiServe
Limited Partnership, an affiliate of BankBoston, N.A.

RESTRICTIONS ON OWNERSHIP AND TRANSFER

     For the Company to qualify as a REIT under the Code, no more than 50% in
value of its outstanding shares of beneficial interest 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 an election to be treated as a REIT has been made) or during a
proportionate part of a shorter taxable year. A REIT's shares also must be
beneficially owned by 100 or more persons during at least 335 days of a taxable
year 



                                       15
<PAGE>   18

of twelve 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 the Board of Trustees believes it is desirable for the Company to
qualify as a REIT, the Declaration of Trust, subject to certain exceptions,
provides that no holder may own, or be deemed to own by virtue of the
attribution provisions of the Code, more than the Ownership Limit. The
Declaration of Trust prohibits ownership, directly or by virtue of the
attribution rules of the Code, by any single shareholder of more than 5% of the
issued and outstanding Common Shares and generally will prohibit ownership,
directly or by virtue of the attributions provisions of the Code, by any single
shareholder of more than 5% of the issued and outstanding shares of any class or
series of the Company's Preferred Shares (collectively, the "Ownership Limit").
Certain beneficial owners of the Zell Holders (i.e., beneficiaries of trusts
established for the benefit of Mr. Zell and his family and the family of Mr.
Robert Lurie, a deceased partner of Mr. Zell) and EPMC, together with the
Starwood Original Owners and Mr. Goldberg (through their potential ownership of
Common Shares) together constitute five individuals for purposes of this test
and, under the Service's rules applicable to determining percentages of
ownership, are deemed to own approximately 4.9% of the value of the outstanding
shares of beneficial interest of the Company. The ownership attribution rules
under the Code are complex and may cause Common Shares 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 5% of the Common Shares (or the acquisition of an interest in an entity
that owns, actually or constructively, Common Shares) by an individual or
entity, could, nevertheless cause that individual or entity, or another
individual or entity, to own constructively in excess of 5% of the outstanding
Common Shares and thus subject such Common Shares to the Ownership Limit. The
Board of Trustees may in its reasonable discretion grant an exemption from the
Ownership Limit with respect to one or more persons who would not be treated as
"individuals" for purposes of the Code if it is satisfied, based upon the advice
of counsel or a ruling from the Service, that such ownership will not cause a
person who is an individual to be treated as owning Common Shares in excess of
the Ownership Limit, applying the applicable constructive ownership rules, and
will not otherwise jeopardize the Company's status as a REIT. As a condition of
such waiver, the Board of Trustees may require undertakings or representations
from the applicant with respect to preserving the REIT status of the Company.
Under certain circumstances, the Board of Trustees may, in its sole and absolute
discretion, grant an exemption for individuals to acquire Preferred Shares in
excess of the Ownership Limit, provided that certain conditions are met and any
representations and undertakings that may be required by the Board of Trustees
are made. The Company's Declaration of Trust also exempts from the Ownership
Limit certain of the beneficial owners of the Original Owners and EPMC, who
would exceed the Ownership Limit as a result of the exchange of the OP Units for
Common Shares, which OP Units were received by them at the time of the formation
of EQR. These persons may also acquire additional shares of beneficial interest
through the Company's Option and Award Plan, but in no event will such persons
be entitled to acquire additional shares such that the five largest beneficial
owners of the Company's shares of beneficial interest hold more than 50% in
number or value of the total outstanding shares of beneficial interest.

     The Board of Trustees of the Company will have the authority to increase
the Ownership Limit from time to time, but will not have the authority to do so
to the extent that after a giving effect to such increase, five beneficial
owners of Common Shares could beneficially own in the aggregate more than 49.5%
of the outstanding Common Shares.

     The Declaration of Trust further prohibits (a) any person from actually or
constructively owning shares of beneficial interest of the Company that would
result in the Company being "closely held" under Section 856(h) of the Code or
otherwise cause the Company to fail to qualify as a REIT and (b) any person from
transferring shares of beneficial interest of the Company if such transfer would
result in shares of beneficial interest of the Company being owned by fewer than
100 persons.

     Any person who acquires or attempts or intends to acquire actual or
constructive ownership of shares of beneficial interest of the Company that will
or may violate any of the foregoing restrictions on transferability and
ownership is required to give notice immediately to the Company and provide the
Company with such other information as the Company may request in order to
determine the effect of such transfer on the Company's status as a REIT.

     If any purported transfer of shares of beneficial interest of the Company
or any other event would otherwise result in any person violating the Ownership
Limit or the other restrictions in the Declaration of Trust, then any such
purported 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 Ownership Limit (referred to as "excess shares") and the
Prohibited Transferee shall acquire no right or interest (or, in the case of any
event other than a purported transfer, the person or entity holding record title
to any such shares in excess of the Ownership Limit (the "Prohibited Owner")
shall cease to own any right or interest) in such excess shares. Any such 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 the Company (the "Beneficiary"). Such automatic transfer shall be
deemed to be effective as of the close of business on the Business Day 




                                       16
<PAGE>   19

(as defined in the Declaration of Trust) prior to the date of such violating
transfer. Within 20 days of receiving notice from the Company of the transfer of
shares to the trust, the trustee of the trust (who shall be designated by the
Company and be unaffiliated with the Company and any Prohibited Transferee or
Prohibited Owner) will be required to sell such excess shares to a person or
entity who could own such shares without violating the Ownership Limit, and
distribute to the Prohibited Transferee an amount equal to the lesser of the
price paid by the Prohibited Transferee for such excess shares or the sales
proceeds received by the trust for such excess shares. In the case of any excess
shares resulting from any event other than a transfer, or from a transfer for no
consideration (such as a gift), the trustee will be required to sell such excess
shares to a qualified person or entity and distribute to the Prohibited Owner an
amount equal to the lesser of the fair market value of such excess shares as of
the date of such event or the sales proceeds received by the trust for such
excess shares. In either case, any proceeds in excess of the amount
distributable to the Prohibited Transferee or Prohibited Owner, as applicable,
will be distributed to the Beneficiary. Prior to a sale of any such excess
shares by the trust, the trustee will be entitled to receive, in trust for the
Beneficiary, all dividends and other distributions paid by the Company with
respect to such excess shares, and also will be entitled to exercise all voting
rights with respect to such excess shares. Subject to Maryland law, effective as
of the date that such shares have been transferred to the trust, the trustee
shall have the authority (at the trustee's sole discretion and subject to
applicable law) (i) to rescind as void any vote cast by a Prohibited Transferee
prior to the discovery by the Company that such shares have been transferred to
the trust and (ii) to recast such vote in accordance with the desires of the
trustee acting for the benefit of the Beneficiary. However, if the Company has
already taken irreversible corporate action, then the trustee shall not have the
authority to rescind and recast such vote. Any dividend or other distribution
paid to the Prohibited Transferee or Prohibited Owner (prior to the discovery by
the Company that such shares had been automatically transferred to a trust as
described above) will be required to be repaid to the trustee upon demand for
distribution to the Beneficiary. If the transfer to the trust as described above
is not automatically effective (for any reason) to prevent violation of the
Ownership Limit, then the Declaration of Trust provides that the transfer of the
excess shares will be void.

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

     The foregoing restrictions on transferability and ownership will not apply
if the Board of Trustees determines that it is no longer in the best interests
of the Company to attempt to qualify, or to continue to qualify, as a REIT.

     All certificates representing shares of beneficial interest shall bear a
legend referring to the restrictions described above.

     All persons who own, directly or by virtue of the attribution provisions of
the Code, more than 5% (or such other percentage between 1/2 of 1% and 5% as
provided in the rules and regulations promulgated under the Code) of the lesser
of the number or value of the outstanding shares of beneficial interest of the
Company must give a written notice to the Company by January 31 of each year. In
addition, each shareholder will, upon demand, be required to disclose to the
Company in writing such information with respect to the direct, indirect and
constructive ownership of shares of beneficial interest as the Board of Trustees
deems reasonably necessary to comply with the provisions of the Code applicable
to a REIT, to comply with the requirements of any taxing authority or
governmental agency or to determine any such compliance.

     These ownership limitations could have the effect of delaying, deferring or
preventing a takeover or other transaction in which holders of some, or a
majority, of Common Shares might receive a premium for their Common Shares over
the then prevailing market price or which such holders might believe to be
otherwise in their best interest.

                        DESCRIPTION OF DEPOSITARY SHARES

GENERAL

     The Company may issue receipts ("Depositary Receipts") for Depositary
Shares, each of which will represent a fractional interest of a share of a
particular series of Preferred Shares, as specified in the applicable Prospectus
Supplement. Preferred Shares of each series represented by Depositary Shares
will be deposited under a separate Deposit Agreement (each, a "Deposit
Agreement") among the Company, the depositary named therein (the "Preferred
Share Depositary") and the holders from time to time of the Depositary Receipts.
Subject to the terms of the Deposit Agreement, each owner of a Depositary
Receipt will be entitled, in proportion to the fractional interest 
of a share of a particular series of Preferred Shares represented by the
Depositary Shares evidenced by such Depositary Receipt, to all the rights and
preferences of the Preferred Shares represented by such Depositary Shares
(including distribution, voting, conversion, redemption and liquidation rights).

     The Depositary Shares will be evidenced by Depositary Receipts issued
pursuant to the applicable Deposit Agreement. Immediately following the issuance
and delivery of the Preferred Shares by the Company to the Preferred Share
Depositary, the Company will cause the Preferred Share Depositary to issue, on
behalf of the Company, the Depositary Receipts. Copies of the applicable form of
Deposit Agreement and Depositary Receipt may be obtained from the Company upon
request, and the following summary of the form thereof filed as an exhibit to
the Registration Statement of which this Prospectus is a part is qualified in
its entirety by reference thereto.

DISTRIBUTIONS

     The Preferred Share Depositary will distribute all cash distributions
received in respect of the Preferred Shares to the record holders of Depositary
Receipts evidencing the related Depositary Shares in proportion to the number of
such Depositary Receipts owned by such holders, subject to certain obligations
of holders to file proofs, certificates and other information and to pay certain
charges and expenses to the Preferred Share Depositary.

     In the event of a distribution other than in cash, the Preferred Share
Depositary will distribute property received by it to the record holders of
Depositary Receipts entitled thereto, subject to certain obligations of holders
to file proofs, certificates and other information and to pay certain charges
and expenses to the Preferred Share Depositary, unless the Preferred Share
Depositary determines that it is not feasible to make such distribution, in
which case the Preferred Share Depositary may, with the approval of the Company,
sell such property and distribute the net proceeds from such sale to such
holders.

     No distribution will be made in respect of any Depositary Share to the
extent that it represents any Preferred Shares converted into excess shares.

WITHDRAWAL OF SHARES

     Upon surrender of the Depositary Receipts at the corporate trust office of
the Preferred Share Depositary (unless the related Depositary Shares have
previously been called for redemption or converted into excess shares), the
holders thereof will be entitled to delivery at such office, to or upon such
holder's order, of the number of whole or fractional Preferred Shares and any
money or other property represented by the Depositary Shares evidenced by such
Depositary Receipts. Holders of Depositary Receipts will be entitled to receive
whole or fractional shares of the related Preferred Shares on the basis of the
proportion of the Preferred Shares represented by each Depositary Share as
specified in the applicable Prospectus Supplement, but holders of such Preferred
Shares will not thereafter be entitled to receive Depositary Shares therefor. If
the Depositary Receipts delivered by the holder evidence a number of Depositary
Shares in excess of the number of Depositary Shares representing the number of
Preferred Shares to be withdrawn, the Preferred Share Depositary will deliver to
such holder at the same time a new Depositary Receipt evidencing such excess
number of Depositary Shares.

REDEMPTION OF DEPOSITARY SHARES

     Whenever the Company redeems Preferred Shares held by the Preferred Share
Depositary, the Preferred Share Depositary will redeem as of the same redemption
date the number of Depositary Shares representing the Preferred Shares so
redeemed, provided the Company shall have paid in full to the Preferred Share
Depositary the redemption price of the Preferred Shares to be redeemed plus an
amount equal to any accrued and unpaid distributions thereon to the date fixed
for redemption. The redemption price per Depositary Share will be equal to the
redemption price and any other amounts per share payable with respect to the
Preferred Shares. If fewer than all the Depositary Shares are to be redeemed,
the Depositary Shares to be redeemed will be selected pro rata (as nearly as may
be practicable without creating fractional Depositary Shares) or by any other
equitable method determined by the Company that will not result in the issuance
of any excess shares.

     From and after the date fixed for redemption, all distributions in respect
of the Preferred Shares so called for redemption will cease to accrue, the
Depositary Shares so called for redemption will no longer be deemed to be
outstanding and all rights of the holders of the Depositary Receipts evidencing
the Depositary Shares so called for redemption will cease, except the right to
receive any monies payable upon such redemption and any money or other property
to which the holders of such Depositary Receipts were entitled upon such
redemption upon surrender thereof to the Preferred Share Depositary.

<PAGE>   21

VOTING OF THE PREFERRED SHARES

     Upon receipt of notice of any meeting at which the holders of the Preferred
Shares are entitled to vote, the Preferred Share Depositary will mail the
information contained in such notice of meeting to the record holders of the
Depositary Receipts evidencing the Depositary Shares which represent such
Preferred Shares. Each record holder of Depositary Receipts evidencing
Depositary Shares on the record date (which will be the same date as the record
date for the Preferred Shares) will be entitled to instruct the Preferred Share
Depositary as to the exercise of the voting rights pertaining to the amount of
Preferred Shares represented by such holder's Depositary Shares. The Preferred
Share Depositary will vote the amount of Preferred Shares represented by such
Depositary Shares in accordance with such instructions, and the Company will
agree to take all reasonable action which may be deemed necessary by the
Preferred Share Depositary in order to enable the Preferred Share Depositary to
do so. The Preferred Share Depositary will abstain from voting the amount of
Preferred Shares represented by such Depositary Shares to the extent it does not
receive specific instructions from the holders of Depositary Receipts evidencing
such Depositary Shares. The Preferred Share Depositary shall not be responsible
for any failure to carry out any instruction to vote, or for the manner or
effect of any such vote made, as long as any such action or non-action is in
good faith and does not result from negligence or willful misconduct of the
Preferred Share Depositary.

LIQUIDATION PREFERENCE

     In the event of the liquidation, dissolution or winding up of the Company,
whether voluntary or involuntary, the holders of each Depositary Receipt will be
entitled to the fraction of the liquidation preference accorded each Preferred
Share represented by the Depositary Share evidenced by such Depositary Receipt,
as set forth in the applicable Prospectus Supplement.

CONVERSION OF PREFERRED SHARES

     The Depositary Shares, as such, are not convertible into Common Shares or
any other securities or property of the Company, except in connection with
certain conversions in connection with the preservation of the Company's status
as a REIT. Nevertheless, if so specified in the applicable Prospectus Supplement
relating to an offering of Depositary Shares, the Depositary Receipts may be
surrendered by holders thereof to the Preferred Share Depositary with written
instructions to the Preferred Share Depositary to instruct the Company to cause
conversion of the Preferred Shares represented by the Depositary Shares
evidenced by such Depositary Receipts into whole Common Shares, other Preferred
Shares (including excess shares) of the Company or other shares of beneficial
interest, and the Company has agreed that upon receipt of such instructions and
any amounts payable in respect thereof, it will cause the conversion thereof
utilizing the same procedures as those provided for delivery of Preferred Shares
to effect such conversion. If the Depositary Shares evidenced by a Depositary
Receipt are to be converted in part only, a new Depositary Receipt or Receipts
will be issued for any Depositary Shares not to be converted. No fractional
Common Shares will be issued upon conversion, and if such conversion will result
in a fractional share being issued, an amount will be paid in cash by the
Company equal to the value of the fractional interest based upon the closing
price of the Common Shares on the last business day prior to the conversion.

AMENDMENT AND TERMINATION OF THE DEPOSIT AGREEMENT

     The form of Depositary Receipt evidencing the Depositary Shares which
represent the Preferred Shares and any provision of the Deposit Agreement may at
any time be amended by agreement between the Company and the Preferred Share
Depositary. However, any amendment that materially and adversely alters the
rights of the holders of Depositary Receipts or that would be materially and
adversely inconsistent with the rights granted to the holders of the related
Preferred Shares will not be effective unless such amendment has been approved
by the existing holders of at least a majority of the Depositary Shares
evidenced by the Depositary Receipts then outstanding. No amendment shall impair
the right, subject to certain exceptions in the Depositary Agreement, of any
holder of Depositary Receipts to surrender any Depositary Receipt with
instructions to deliver to the holder the related Preferred Shares and all money
and other property, if any, represented thereby, except in order to comply with
law. Every holder of an outstanding Depositary Receipt at the time any such
amendment becomes effective shall be deemed, by continuing to hold such
Depositary Receipt, to consent and agree to such amendment and to be bound by
the Deposit Agreement as amended thereby.

     The Deposit Agreement may be terminated by the Company upon not less than
30 days' prior written notice to the Preferred Share Depositary if (i) such
termination is necessary to assist in maintaining the Company's status as a REIT
or (ii) a majority of each series of Preferred Shares affected by such
termination consents to such termination, whereupon the Preferred Share
Depositary shall deliver or make available to each holder of Depositary
Receipts, upon surrender of the Depositary Receipts held by such holder, such
number of 




                                       19
<PAGE>   22

whole or fractional Preferred Shares as are represented by the Depositary Shares
evidenced by such Depositary Receipts together with any other property held by
the Preferred Share Depositary with respect to such Depositary Receipts. The
Company has agreed that if the Deposit Agreement is terminated to assist in
maintaining the Company's status as a REIT, then, if the Depositary Shares are
listed on a national securities exchange, the Company will use its best efforts
to list the Preferred Shares issued upon surrender of the related Depositary
Shares on a national securities exchange. In addition, the Deposit Agreement
will automatically terminate if (i) all outstanding Depositary Shares shall have
been redeemed, (ii) there shall have been a final distribution in respect of the
related Preferred Shares in connection with any liquidation, dissolution or
winding up of the Company and such distribution shall have been distributed to
the holders of Depositary Receipts evidencing the Depositary Shares representing
such Preferred Shares or (iii) each share of the related Preferred Shares shall
have been converted into shares of beneficial interest of the Company not so
represented by Depositary Shares.

CHARGES OF PREFERRED SHARE DEPOSITARY

     The Company will pay all transfer and other taxes and governmental charges
arising solely from the existence of the Deposit Agreement. In addition, the
Company will pay the fees and expenses of the Preferred Share Depositary in
connection with the performance of its duties under the Deposit Agreement.
However, holders of Depositary Receipts will pay certain other transfer and
other taxes and governmental charges as well as the fees and expenses of the
Preferred Share Depositary for any duties requested by such holders to be
performed which are outside of those expressly provided for in the Deposit
Agreement.

RESIGNATION AND REMOVAL OF DEPOSITARY

     The Preferred Share Depositary may resign at any time by delivering to the
Company notice of its election to do so, and the Company may at any time remove
the Preferred Share Depositary, any such resignation or removal to take effect
upon the appointment of a successor Preferred Share Depositary. A successor
Preferred Share Depositary must be appointed within 60 days after delivery of
the notice of resignation or removal and must be a bank or trust company having
its principal office in the United States and having a combined capital and
surplus of at least $50,000,000.

MISCELLANEOUS

     The Preferred Share Depositary will forward to holders of Depositary
Receipts any reports and communications from the Company which are received by
the Preferred Share Depositary with respect to the related Preferred Shares.

     Neither the Preferred Share Depositary nor the Company will be liable if it
is prevented from or delayed in, by law or any circumstances beyond its control,
performing its obligations under the Deposit Agreement. The obligations of the
Company and the Preferred Share Depositary under the Deposit Agreement will be
limited to performing their duties thereunder in good faith and without
negligence (in the case of any action or inaction in the voting of Preferred
Shares represented by the Depositary Shares), gross negligence or willful
misconduct, and the Company and the Preferred Share Depositary will not be
obligated to prosecute or defend any legal proceeding in respect of any
Depositary Receipts, Depositary Shares or Preferred Shares represented thereby
unless satisfactory indemnity is furnished. The Company and the Preferred Share
Depositary may rely on written advice of counsel or accountants, or information
provided by persons presenting Preferred Shares represented thereby for deposit,
holders of Depositary Receipts or other persons believed in good faith to be
competent to give such information, and on documents believed in good faith to
be genuine and signed by a proper party.

     In the event the Preferred Share Depositary shall receive conflicting
claims, requests or instructions from any holders of Depositary Receipts, on the
one hand, and the Company, on the other hand, the Preferred Share Depositary
shall be entitled to act on such claims, requests or instructions received from
the Company.

 RATIOS OF EARNINGS TO COMBINED FIXED CHARGES AND PREFERRED SHARE DISTRIBUTIONS

     The following table sets forth the Company's ratios of earnings to combined
fixed charges and preferred share distributions for the periods shown.

</TABLE>

     Ratio of earnings to combined fixed charges and preferred share
distributions represents the ratio of income before gain on disposition of
properties, extraordinary items and allocation to minority interests plus fixed
charges (principally interest expense incurred) to fixed charges and preferred
share distributions.

     The reorganization and recapitalization of the Company effected in
connection with the EQR IPO in 1993 permitted the Company to significantly
deleverage the Properties resulting in an improved ratio of earnings to combined
fixed charges and preferred share distributions for periods subsequent to the
EQR IPO.

                        FEDERAL INCOME TAX CONSIDERATIONS

GENERAL

     The following discussion summarizes the federal income tax considerations 
anticipated to be material to a holder of Common Shares. The applicable 
Prospectus Supplement will contain information about additional federal income
tax considerations, if any, relating to Securities other than Common Shares. The
following discussion, which is not exhaustive of all possible tax
considerations, does not give a detailed discussion of any state, local or
foreign tax considerations. Nor does it discuss all of the aspects of federal
income taxation that may be relevant to a prospective shareholder in light of
his or her particular circumstances or to certain types of shareholders
(including insurance companies, tax-exempt entities, financial institutions or
broker-dealers, foreign corporations and persons who are not citizens or
residents of the United States) who are subject to special treatment under the
federal income tax laws.

     EACH PROSPECTIVE PURCHASER OF SECURITIES IS ADVISED TO CONSULT WITH HIS OR
HER OWN TAX ADVISOR REGARDING THE SPECIFIC TAX CONSEQUENCES TO HIM OR HER, IN
LIGHT OF HIS OR HER SPECIFIC OR UNIQUE CIRCUMSTANCES, OF THE PURCHASE, OWNERSHIP
AND SALE OF SECURITIES IN AN ENTITY ELECTING TO BE TAXED AS A REIT, INCLUDING
THE FEDERAL, STATE, LOCAL, FOREIGN AND OTHER TAX CONSEQUENCES OF SUCH PURCHASE,
OWNERSHIP, SALE AND ELECTION AND OF POTENTIAL CHANGES IN APPLICABLE TAX LAWS.

TAXATION OF THE COMPANY

     The Company elected REIT status commencing with its taxable year ended 
December 31, 1992. In any taxable year in which the Company qualifies as a REIT,
it generally will not be subject to federal income tax on that portion of its
REIT taxable income or capital gain which it distributes to shareholders. This
treatment substantially eliminates the "double taxation" (at both the corporate
and shareholder levels) that generally results from the use of corporate
investment vehicles. However, the Company will be subject to federal income tax
at regular corporate rates upon any of its REIT taxable income or net capital
gain which is not distributed to its shareholders. The Company also may be
subject to the corporate "alternative minimum tax" on its items of preference.
In addition, the Company will be subject to a 4% excise tax if it does not
satisfy certain distribution requirements. The Company may also be subject to
taxes in certain situations and on certain transactions not presently
contemplated.

     If the Company fails to qualify for taxation as a REIT in any taxable year,
the Company will be subject to tax (including any applicable alternative minimum
tax) on its taxable income at regular corporate rates. As a result, the
Company's failure to qualify as a 




                                       21
<PAGE>   24

REIT would significantly reduce the cash available for distribution by the
Company to its shareholders. Unless entitled to relief under the specific
statutory provisions, the Company also will be disqualified from taxation as a
REIT for the four taxable years following the year during which qualification
was lost. It is not possible to state whether in all circumstances the Company
would be entitled to such statutory relief.

     The Company's qualification and taxation as a REIT depend upon the
Company's ability to satisfy on a continuing basis, through actual annual
operating and other results, various requirements under the Code, with regard
to, among other things, the sources of the Company's gross income, the
composition of its assets, the level of its dividends to shareholders, and the
diversity of its share ownership. The purpose of these requirements is to allow
the tax benefit of REIT status only to companies that primarily own, and
primarily derive income from, real estate-related assets and certain other
assets which are passive in nature, and that distribute 95% of taxable income
(computed without regard to the Company's net capital gain) to shareholders. The
Company believes that it has qualified as a REIT for all of its taxable years
commencing with its taxable year ended December 31, 1992, and that its current
structure and method of operation is such that it will continue to qualify as a
REIT.

     Hogan & Hartson L.L.P., special tax counsel to the Company, has provided an
opinion to the effect that the Company was organized and has operated in
conformity with the requirements for qualification and taxation as a REIT under
the Code for its taxable year ended December 31, 1997, and the Company's current
organization and method of operation should enable it to continue to meet the
requirements for qualification and taxation as a REIT. It must be emphasized
that this opinion is based on various assumptions and factual representations
made by the Company and the Operating Partnership (which for the purposes of the
Section include both ERP Operating Limited Partnership and Evans Withycombe
Residential, L.P.) relating to the organization, prior and expected operation of
the Company (including its predecessors EQR and Wellsford), the Operating
Partnership, and all of the various partnerships, limited liability companies
and corporate entities in which the Company presently has an ownership interest,
or in which the Company (including its predecessors EQR and Wellsford) had an
ownership interest in the past. Hogan & Hartson L.L.P. will not review the
Company's compliance with these requirements on a continuing basis. No assurance
can be given that the actual results of the operations of the Company, the
Operating Partnership, and the subsidiary entities, the sources of their gross
income, the composition of their assets, the level of the Company's dividends to
shareholders and the diversity of its share ownership for any given taxable year
will satisfy the requirements under the Code for qualification and taxation as a
REIT.

TAXATION OF TAXABLE DOMESTIC SHAREHOLDERS

     General. As long as the Company qualifies as a REIT, distributions made to
the Company's taxable domestic shareholders, with respect to their Common Shares
out of current or accumulated earnings and profits (and not designated as
capital gain dividends) will be taken into account by them as ordinary income
and will not be eligible for the dividends received deduction for shareholders
that are corporations. For purposes of determining whether distributions on the
Common Shares are out of current or accumulated earnings and profits, the
earnings and profits of the Company will be allocated first to the Preferred
Shares of the Company and second to the Common Shares. There can be no
assurance, however, that the Company will have sufficient earnings and profits
to cover distributions on the Preferred Shares.

     Distributions made by the Company that are properly designated by the
Company as capital gain dividends will be taxable to taxable domestic
shareholders, who are individuals, estates or trusts, as gain from the sale or
exchange of a capital asset held for more than one year (to the extent they do
not exceed the Company's actual net capital gain for the taxable year) without
regard to the period for which a domestic shareholder has held his Common
Shares.

     On November 10, 1997, the Service issued IRS Notice 97-64, which provides
generally that the Company may classify portions of its designated capital gains
dividend as (i) a 20% rate gain distribution (which would be taxable to taxable
domestic shareholders who are individuals, estates or trusts at a maximum rate
of 20%), (ii) an unrecaptured Section 1250 gain distribution (which would be
taxable to taxable domestic shareholders who are individuals, estates or trusts
at a maximum rate of 25%), or (iii) a 28% rate gain distribution (which would be
taxable to taxable domestic shareholders who are individuals, estates or trusts
at a maximum rate of 28%). (If no designation is made, the entire designated
capital gain dividend will be treated as a 28% rate gain distribution.) Notice
97-64 provides that a REIT must determine the maximum amounts that it may
designate as 20% and 25% rate capital gain dividends by performing the
computation required by the Code as if the REIT were an individual whose
ordinary income were subject to a marginal tax rate of at least 28%. Notice
97-64 further provides that designations made by the REIT only will be effective
to the extent that they comply with Revenue Ruling 89-81, which requires that
distributions made to different classes of shares be composed proportionately of
dividends of a particular type.

     Distributions that are properly designated by the Company as capital gain
dividends will be taxable to taxable corporate domestic shareholders as
long-term capital gain (to the extent that capital gains dividends do not exceed
the Company's actual net capital gain for 



                                       22
<PAGE>   25
the taxable year) without regard to the period for which such corporate domestic
shareholder has held his Common Shares. Such corporate domestic shareholders
may, however, be required to treat up to 20% of certain capital gain dividends
as ordinary income.

     If, for any taxable year, the Company elects to designate as "capital gain
dividends" (as defined in Section 857 of the Code) any portion (the "Capital
Gains Amount") of the dividends (within the meaning of the Code) paid or made
available for the year to holders of all classes of shares of beneficial
interest (the "Total Dividends"), then the portion of the Capital Gains Amount
that will be allocable to the holders of Common Shares will be the Capital Gains
Amount multiplied by a fraction, the numerator of which will be the total
dividends (within the meaning of the Code) paid or made available to the holders
of the Common Shares for the year and the denominator of which shall be the
Total Dividends. To the extent that the Company makes distributions in excess of
current and accumulated earnings and profits, these distributions are treated
first as a tax-free return of capital to the shareholder, reducing the tax basis
of a shareholder's Common Shares by the amount of such distribution (but not
below zero), with distributions in excess of the shareholder's tax basis taxable
as capital gains (if the Common Shares are held as a capital asset). In
addition, any dividend declared by the Company in October, November or December
of any year and payable to a shareholder of record on a specific date in any
such month shall be treated as both paid by the Company and received by the
shareholder on December 31 of such year, provided that the dividend is actually
paid by the Company during January of the following calendar year. Shareholders
may not include in their individual income tax returns any net operating losses
or capital losses of the Company.

     In general, upon any sale or other disposition of Common Shares, a
shareholder will recognize gain or loss for federal income tax purposes in an
amount equal to the difference between (i) the amount of cash and the fair
market value of any property received on such sale or other disposition and (ii)
the holder's adjusted basis in such Common Shares for tax purposes. Such gain or
loss will be capital gain or loss if the Common Shares have been held as a
capital asset. In the case of a shareholder that is a corporation, such capital
gain or loss will be long-term capital gain or loss if such Common Shares have
been held for more than one year. Generally, in the case of a taxable domestic
shareholder who is an individual or an estate or trust, such capital gain or
loss will be taxed (i) at a maximum rate of 20% if such Common Shares have been
held for more than 18 months; (ii) at a maximum rate of 28% if such Common
Shares have been held for more than one year but not more than 18 months; and 
(iii) for dispositions occurring after December 31, 2000, at a maximum rate
of 18% if the Common Shares have been held for more than five years.
The Taxpayer Relief Act of 1997 (the "1997 Act") allows the Service to issue
regulations relating to the manner in which the 1997 Act's new capital gain
rates will apply to sales of capital assets by "pass-through entities," which
include REITs such as the Company, and to sales of interests in "pass-through
entities." To date, the Service has not issued such regulations (but see
discussion of Notice 97-64 above), but if issued, such regulations could affect
the taxation of gain and loss realized on the disposition of Common Shares.
Shareholders are urged to consult with their own tax advisors with respect to
the new rules contained in the 1997 Act. In general, any loss recognized by a
shareholder upon the sale or other disposition of Common Shares that have been
held for six months or less (after applying certain holding period rules) will
be treated as long-term capital loss, to the extent of distributions received
by such shareholder from the Company which were required to be treated as
long-term capital gains. For shareholders who are individuals, trusts and
estates, the long-term capital loss will be apportioned among the applicable
long-term capital gain groups to the extent that distributions received by such
shareholder were previously so treated.

     The Company may elect to require holders of Common Shares to include the
Company's undistributed net capital gains in their income. If the Company makes
such an election, holders of Common Shares will (i) include in their income as
long-term capital gains their proportionate share of such undistributed capital
gains and (ii) be deemed to have paid their proportionate share of the tax paid
by the Company on such undistributed capital gains and thereby receive a credit
or refund for such amount. A holder of Common Shares will increase the basis in
its Common Shares by the difference between the amount of capital gain included
in its income and the amount of the tax it is deemed to have paid. The earnings
and profits of the Company will be adjusted appropriately.

     Additional Tax Consequences for Holders of Preferred Shares and Depositary
Shares. If the Company offers one or more series of Preferred Shares or
Depositary Shares, then there may be additional tax consequences for the holders
of such Preferred Shares or Depositary Shares. For a discussion of any such
additional consequences, see the applicable Prospectus Supplement.
 
TAXATION OF TAX-EXEMPT SHAREHOLDERS

     Most tax-exempt employees' pension trusts are not subject to federal income
tax except to the extent of their receipt of "unrelated business taxable income"
as defined in Section 512(a) of the Code ("UBTI"). Distributions by the Company
to a shareholder that is a tax-exempt entity should not constitute UBTI,
provided that the tax-exempt entity has not financed the acquisition of its
Common Shares with "acquisition indebtedness" within the meaning of the
Code and the Common Shares are not otherwise used in an unrelated trade or
business of the tax-exempt entity. In addition,  certain pension trusts that
own more than 10% of a "pension-held REIT" must report a portion of the
distribution that they receive from such a REIT as UBTI. The Company has not
been and does not expect to be treated as a pension-held REIT for purposes of
this rule.

TAXATION OF FOREIGN SHAREHOLDERS

     The following is a discussion of certain anticipated U.S. federal income
tax consequences of the ownership and disposition of Common Shares applicable to
Non-U.S. Holders of such Common Shares. A "Non-U.S. Holder" is any person other
than (i) a citizen or resident of the United States, (ii) a corporation or
partnership created or organized in the United States or under the laws of the
United States or of any state thereof, or (iii) an estate or trust whose income
is includable in gross income for U.S. federal income tax purposes regardless of
its source. The discussion is based on current law and is for general
information only.


                                       23
<PAGE>   26

     Distributions From the Company. 1. Ordinary Dividends. The portion of
dividends received by Non-U.S. Holders payable out of the Company's earnings and
profits which are not attributable to capital gains of the Company or of the
Operating Partnership and which are not effectively connected with a U.S. trade
or business of the Non-U.S. Holder will be subject to U.S. withholding tax at
the rate of 30% (unless reduced by an applicable treaty). In general, Non-U.S.
Holders will not be considered engaged in a U.S. trade or business solely as a
result of their ownership of Common Shares. In cases where the dividend income
from a Non-U.S. Holder's investment in Common Shares is (or is treated as)
effectively connected with the Non-U.S. Holder's conduct of a U.S. trade or
business, the Non-U.S. Holder generally will be subject to U.S. tax at graduated
rates, in the same manner as U.S. shareholders are taxed with respect to such
dividends (and may also be subject to the 30% branch profits tax in the case of
a Non-U.S. Holder that is a foreign corporation).

     2. Non-Dividend Distributions. Distributions in excess of current or
accumulated earnings and profits of the Company will not be taxable to a 
Non-U.S. Holder to the extent that they do not exceed the adjusted basis of the
shareholder's Common Shares, but rather will reduce the adjusted basis of such
Common Shares. To the extent that such distributions exceed the adjusted basis
of a Non-U.S. Holder's Common Shares, they will give rise to gain from the sale
or exchange of its Common Shares, the tax treatment of which is described below.
As a result of a legislative change made by the Small Business Job Protection
Act of 1996, it appears that the Company will be required to withhold 10% of any
distribution in excess of the Company's current and accumulated earnings and
profits. Consequently, although the Company intends to withhold at a rate of 30%
on the entire amount of any distribution (or a lower applicable treaty rate), to
the extent that the Company does not do so, any portion of a distribution not
subject to withholding at a rate of 30% (or a lower applicable treaty rate) will
be subject to withholding at a rate of 10%. However, the Non-U.S. Holder may
seek a refund of such amounts from the Service if it was subsequently determined
that such distribution was, in fact, in excess of current or accumulated
earnings and profits of the Company, and the amount withheld exceeded the 
Non-U.S. Holder's United States tax liability, if any, with respect to the
distribution.

     3. Capital Gain Dividends. Under the Foreign Investment in Real Property
Tax Act of 1980 ("FIRPTA"), a distribution made by the Company to a Non-U.S.
Holder, to the extent attributable to gains from dispositions of United States
Real Property Interests ("USRPIs") such as the Properties beneficially owned by
the Company ("USRPI Capital Gains"), will be considered effectively connected
with a U.S. trade or business of the Non-U.S. Holder and subject to U.S. income
tax at the rate applicable to U.S. individuals or corporations, without regard
to whether such distribution is designated as a capital gain dividend. In
addition, the Company will be required to withhold tax equal to 35% of the
amount of dividends to the extent such dividends constitute USRPI Capital Gains.
Distributions subject to FIRPTA may also be subject to a 30% branch profits tax
in the hands of a foreign corporate shareholder that is not entitled to treaty
exemption. That amount is creditable against the Non-U.S. Holder's U.S. federal
income tax liability.

     Although the law is not entirely clear on the matter, it appears that
amounts designated by the Company pursuant to the 1997 Act as undistributed
capital gains in respect of shares would be treated with respect to Non-U.S.
Holders in the manner outlined in the preceding paragraph for actual
distributions by the Company of capital gain dividends. Under that approach, the
Non-U.S. Holders would be able to offset as a credit against their United States
federal income tax liability resulting therefrom their proportionate share of
the tax paid by the Company on such undistributed capital gains (and to receive
from the IRS a refund to the extent their proportionate share of such tax paid
by the Company were to exceed their actual United States federal income tax
liability).

     Dispositions of Common Shares. Unless Common Shares constitute a USRPI, a
sale of Common Shares by a Non-U.S. Holder generally will not be subject to U.S.
taxation under FIRPTA. The Common Shares will not constitute a USRPI if the
Company is a "domestically controlled REIT." A domestically controlled REIT is a
REIT in which, at all times during a specified testing period, less than 50% in
value of its Common Shares is held directly or indirectly by Non-U.S. Holders.
The Company believes that it has been and anticipates that it will continue to
be a domestically controlled REIT, and therefore that the sale of Common Shares
will not be subject to taxation under FIRPTA. Because the Common Shares will be
publicly traded, however, no assurance can be given the Company will continue to
be a domestically controlled REIT. If the Company does not constitute a
domestically controlled REIT, a Non-U.S. Holder's sale of shares of beneficial
interest of the Company generally will still not be subject to tax under FIRPTA
as a sale of a USRPI provided that (i) such shares are "regularly traded" (as
defined by applicable Treasury regulations) on an established securities market
and (ii) the selling Non-U.S. Holder does not hold more than 5% of the value of
the series and class of the Company's outstanding shares being sold, at all
times during a specified testing period.

     If gain on the sale of Common Shares were subject to taxation under FIRPTA,
the Non-U.S. Holder would be subject to the same treatment as a U.S. shareholder
with respect to such gain (subject to applicable alternative minimum tax and a
special alternative minimum tax in the case of nonresident alien individuals)
and the purchaser of Common Shares could be required to withhold 10% of the




                                       24
<PAGE>   27

purchase price and remit such amount to the Service.  Capital gains not subject 
to FIRPTA will nonetheless be taxable in the United States to a Non-U.S. Holder
in two cases: (i) if the Non-U.S. Holder's investment in Common Shares is
effectively connected with a U.S. trade or business conducted by such Non-U.S.
Holder, the Non-U.S. Holder will be subject to the same treatment as a U.S.
shareholder with respect to such gain, or (ii) if the Non-U.S. Holder is a
nonresident alien individual who was present in the United States for 183 days
or more during the taxable year and has a "tax home" in the United States, the
nonresident alien individual will be subject to a 30% tax on the individual's
capital gain.

OTHER TAX CONSIDERATIONS

     Recent Legislation. In addition to the provisions discussed above, the
1997 Act contains a number of technical provisions that either (i) reduce the
risk that the Company will inadvertently cease to qualify as a REIT or (ii)
provide additional flexibility with which the Company can meet the REIT
qualification requirements. These provisions are effective for the Company's
taxable years commencing on or after January 1, 1998.

     The Management Corps. A portion of the cash to be used by the Operating
Partnership to fund distributions to its partners, including the Company, is
expected to come from Equity Residential Properties Management Corp., Equity
Residential Properties Management Corp. II, Equity Residential Properties
Management Corp. III, Wellsford Holly Management, Inc. and Evans Withycombe
Management, Inc. (collectively, the "Management Corps.") through payments of
dividends on the non-voting stock of the Management Corps. held by the Operating
Partnership. The Management Corps., among other things, own interests in the
Management Partnerships. The Management Corps. pay federal and state income tax
at the full applicable corporate rates. The Management Corps. will attempt to
minimize the amount of such taxes, but there can be no assurance whether or the
extent to which measures taken to minimize taxes will be successful. To the
extent that the Management Corps. are required to pay federal, state or local
taxes, the cash available for distribution by the Company to shareholders will
be reduced accordingly.

     State and Local Taxes. The Company and its shareholders may be subject to
state or local taxation in various jurisdictions, including those in which it or
they transact business or reside. The state and local tax treatment of the
Company and its shareholders may not conform to the federal income tax
consequences discussed above. Consequently, prospective shareholders should
consult their own tax advisors regarding the effect of state and local tax laws
on an investment in the shares of beneficial interest of the Company.

                              PLAN OF DISTRIBUTION

     The Company may sell the Securities to one or more underwriters for public
offering and sale by them or may sell the Securities to investors directly or
through agents. Any such underwriter or agent involved in the offer and sale of
the Securities will be named in the applicable Prospectus Supplement.

     The Company may offer and sell the Securities at a fixed price or prices,
which may be changed, at prices related to the prevailing market prices at the
time of sale or at negotiated prices for cash or assets in transactions that do
not constitute a business combination within the meaning of Rule 145 promulgated
under the Securities Act. The Company also may, from time to time, authorize
underwriters acting as the Company's agents to offer and sell the Securities
upon the terms and conditions as are set forth in the applicable Prospectus
Supplement. In connection with the sale of the Securities, underwriters may be
deemed to have received compensation from the Company in the form of
underwriting discounts or commissions and may also receive commissions from
purchasers of the Securities for whom they may act as agent. Underwriters may
sell Securities to or through dealers, and such dealers may receive compensation
in the form of discounts, concessions or commissions from the underwriters
and/or commissions from the purchasers for whom they may act as agent.

     Any underwriting compensation paid by the Company to underwriters or agents
in connection with the offering of the Securities, and any discounts,
concessions or commissions allowed by underwriters to participating dealers,
will be set forth in the applicable Prospectus Supplement. Underwriters, dealers
and agents participating in the distribution of the Securities may be deemed to
be underwriters, and any discounts and commissions received by them and any
profit realized by them on resale of the Securities may be deemed to be
underwriting discounts and commissions, under the Securities Act. Underwriters,
dealers and agents may be entitled, under agreements entered into with the
Company, to indemnification against and contribution toward certain civil
liabilities, including liabilities under the Securities Act.

     If so indicated in the applicable Prospectus Supplement, the Company will
authorize dealers acting as the Company's agents to solicit offers by certain
institutions to purchase Securities from the Company at the public offering
price set forth in such Prospectus Supplement pursuant to Delayed Delivery
Contracts ("Contracts") providing for payment and delivery on the date or dates
stated in such Prospectus Supplement. Each Contract will be for an amount not
less than, and the aggregate principal amount of Securities sold pursuant to
Contracts shall be not less nor more than, the respective amounts stated in the
applicable Prospectus Supplement. Institutions with whom Contracts, when
authorized, may be made include commercial and savings banks, insurance
companies, pension funds, investment companies, educational and charitable
institutions, and other institutions but will in all cases be subject to the
approval of the Company. Contracts will not be subject to any conditions except
(i) the purchase by an institution of the Securities covered by its Contracts
shall not at the time of delivery be prohibited under the laws of any
jurisdiction in the United States to which such institution is subject, and (ii)
if the Securities are being sold to underwriters, the Company shall have sold to
such underwriters the total principal amount of the Securities less the
principal amount thereof covered by Contracts.

     Certain of the underwriters and their affiliates may engage in transactions
with and perform services for the Company and its Subsidiaries in the ordinary
course of business.

ITEM 15. INDEMNIFICATION OF TRUSTEES AND OFFICERS

         Under Maryland law, a real estate investment trust formed in Maryland
is permitted to eliminate, by provision in its Declaration of Trust, the
liability of trustees and officers to the trust and its shareholders for money
damages except for liability resulting from (a) actual receipt of an improper
benefit or profit in money, property or services or (b) acts or omissions
established by a final judgment as involving active and deliberate dishonesty
and being material to the matter giving rise to the proceeding. The Company's
Declaration of Trust includes such a provision eliminating such liability to the
maximum extent permitted by Maryland law.

         The Maryland REIT law, effective October 1, 1994, permits a Maryland
real estate investment trust to indemnify and advance expenses to its trustees,
officers, employees and agents to the same extent as permitted by the MGCL for
directors and officers of Maryland corporations. In accordance with the MGCL,
the Company's bylaws require it to indemnify (a) any present or former trustee,
officer or shareholder or any individual who, while a trustee, officer or
shareholder, served or is serving as a trustee, officer, director, shareholder
or partner of another entity at the Company's express request who has been
successful, on the merits or otherwise, in the defense of a proceeding to which
he was made a party by reason of service in such capacity, against reasonable
expenses incurred by him in connection with the proceeding, (b) any present or
former trustee or officer or any individual who, while a trustee or officer
served or is serving as a trustee, officer, director, shareholder or partner of
another entity at the Company's express request against any claim or liability
to which he may become subject by reason of service in such capacity unless it
is established that (i) his act or omission 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, (ii) he actually received an improper personal
benefit in money, property or services or (iii) in the case of a criminal
proceeding, he had reasonable cause to believe that his act or omission was
unlawful and (c) any present or former shareholder against any claim or
liability to which he may become subject by reason of such status. In addition,
the Company's bylaws require it to pay or reimburse, in advance of final
disposition of a proceeding, reasonable expenses incurred by a present or former
trustee, officer or shareholder or any individual who, while a trustee, officer
or shareholder, served or is serving as a trustee, officer, director,
shareholder or partner of another entity at the Company's express request made a
party to a proceeding by reason of such status, provided that, in the case of a
trustee or officer, the Company shall have received (1) a written affirmation by
such person of his good faith belief that he has met the standard of conduct
necessary for indemnification by the Company as authorized by the bylaws and (2)
a written undertaking by or on his behalf to repay the amount paid or reimbursed
by the Company if it shall ultimately be determined that the applicable standard
of conduct was not met. The Company's bylaws also (x) permit the Company to
provide indemnification and payment or reimbursement of expenses to a present or
former trustee, officer or shareholder who served a predecessor of the Company
or to any employee or agent of the Company or a predecessor of the Company, (y)
provide that any indemnification and payment or reimbursement of the expenses
permitted by the bylaws shall be furnished in accordance with the procedures
provided for indemnification and payment or reimbursement of expenses under
Section 2-418 of the MGCL for directors of Maryland corporations and (z) permit
the Company to provide to the trustees and officers such other and further
indemnification or payment or reimbursement of expenses to the fullest extent
permitted by Section 2-418 of the MGCL for directors of Maryland corporations.

         The Company has entered into indemnification agreements with each of
its trustees and executive officers. The indemnification agreements require,
among other things, that the Company indemnify its trustees and executive
officers to the fullest extent permitted by law and advance to the trustees and
executive officers all related expenses, subject to reimbursement if it is
subsequently determined that indemnification is not permitted. Under these
agreements, the Company must also indemnify and advance all expenses incurred by
trustees and executive officers seeking to enforce their rights under the
indemnification agreements 




                                      II-1
<PAGE>   32

and may cover trustees and executive officers under the Company's trustees and
officers' liability insurance. Although the form of indemnification agreement
offers substantially the same scope of coverage afforded by law, as a
traditional form of contract it may provide greater assurance to trustees and
executive officers that indemnification will be available.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to trustees and officers of the Company pursuant to the
foregoing provisions or otherwise, the Company has been advised that, although
the validity and scope of the governing statute have not been tested in court,
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 addition, indemnification may be limited by state securities
laws.

         The partnership agreements of the Operating Partnership and the
Management Partnerships also provide for indemnification of the Company and its
officers and trustees to the same extent that indemnification is provided to
officers and trustees of the Company in its Declaration of Trust, and limit the
liability of the Company and its officers and trustees to the Operating
Partnership and the Management Partnerships and their respective partners to the
same extent that the liability of the officers and trustees of the Company to
the Company and its shareholders is limited under the Company's Declaration of
Trust.

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 this registration statement.
               Notwithstanding the foregoing, any increase or decrease in volume
               of Securities (if the total dollar value of Securities would not
               exceed that which was registered) and any deviation from the low
               or high end of the estimated maximum offering range may be
               reflected in the form of prospectus filed with the Commission
               pursuant to Rule 424(b) if, in the aggregate, the changes in
               volume and price represent no more than a 20 percent change in
               the maximum aggregate offering price set forth in the
               "Calculation of Registration Fee" table in the effective
               registration statement;




                                       II-2
<PAGE>   33

         (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 this
               registration statement;

provided, however, that subparagraphs (i) and (ii) above do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in the periodic reports filed with or furnished to the Commission by
the Registrant pursuant to Section 13 or Section 15(d) of the Securities
Exchange Act of 1934 that are incorporated by reference in this 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 herein, 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.

         The undersigned Registrant hereby further undertakes that, for the
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 Section
15(d) of the Securities Exchange Act of 1934 that is incorporated by reference
in this 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.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to existing provisions or arrangements whereby the
registrant may indemnify a trustee, officer or controlling person of the
registrant against liabilities arising under the Securities Act of 1933, 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 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 trustee, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such trustee, 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 Act and will
be governed by the final adjudication of such issue.

Registrant certifies that it has reasonable grounds to believe that it meets all
the requirements for filing on Form S-3 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Chicago, State of Illinois, on January 30, 1998.

Board of Trustees
Equity Residential Properties Trust
Two North Riverside Plaza
Suite 400
Chicago, Illinois  60606

Ladies and Gentlemen:

     We are acting as counsel to Equity Residential Properties Trust, a
Maryland real estate investment trust (the "Company"), in connection with its
registration statement on Form S-3 (the "Registration Statement") filed with
the Securities and Exchange Commission relating to the proposed public offering
of up to $1,000,000,000 in aggregate amount of its common shares of beneficial
interest, $.01 par value per share ("Common Shares") and one or more series of
its (i) preferred shares of beneficial interest, $.01 par value per share (the
"Preferred Shares") and (ii) depositary shares representing fractional
interests in Preferred Shares (the "Depositary Shares" and, together with the
Preferred Shares and Common Shares, the "Securities"), all of which Securities
may be offered and sold by the Company from time to time as set forth in the
prospectus which forms a part of the Registration Statement (the "Prospectus"),
and as to be set forth in one or more supplements to the Prospectus (each, a
"Prospectus Supplement").  This opinion letter is furnished to you at your
request to enable you to fulfill the requirements of Item 601(b)(5) of
Regulation S-K, 17 C.F.R. Section  229.601(b)(5), in connection with the
Registration Statement.

     We assume that the classification, terms and conditions, amount, issuance
and sale of the Securities to be offered from time to time will be duly
authorized and determined by proper action by the Board of Trustees of the
Company consistent with the procedures and terms described in the Registration
Statement (each, a "Board Action") and in accordance with the Company's Second
Amended and Restated Declaration of Trust, as amended (the "Declaration of
Trust"), and applicable Maryland law.  We further assume that prior to any
issuance of Preferred Shares or Depositary Shares, appropriate articles
supplementary shall be filed for recordation with the Maryland State Department
of Assessments and Taxation (each, "Articles Supplementary").  We further
assume that any Depositary Shares will be issued by the Depositary (as defined
below) under one or more deposit agreements (each, a "Deposit Agreement"), each
to be between the Company and a financial institution identified therein as the
depositary (each, a "Depositary").

     For purposes of this opinion letter, we have examined copies of the
following documents:

     1.   An executed copy of the Registration Statement.

     2.   The Declaration of Trust, as certified by the Secretary of
          the Company on the date hereof as then being complete, accurate and
          in effect.


<PAGE>   2


Board of Trustees

      3.   The Second Amended and Restated Bylaws of the Company, as
           certified by the Secretary of the Company on the date hereof as then
           being complete, accurate and in effect.

      4.   The form of Deposit Agreement between the Company and the
           financial institution to be named therein, incorporated by reference
           in the Registration Statement as Exhibit 4.3 thereto.

      5.   Resolutions of the Board of Trustees of the Company adopted
           on January 14, 1998, as certified by the Secretary of the Company on
           the date hereof as then being complete, accurate and in effect,
           relating to the filing of the Registration Statement and related
           matters.

      In our examination of the aforesaid documents, we have assumed the
genuineness of all signatures, the legal capacity of natural persons, the
accuracy and completeness of all documents submitted to us, the authenticity of
all original documents, and the conformity to authentic original documents of
all documents submitted to us as certified, telecopied, photostatic, or
reproduced copies.  We have also assumed the accuracy, completeness and
authenticity of the foregoing certifications of trust officers and statements
of fact, on which we are relying, and we have made no independent
investigations thereof.  This opinion letter is given, and all statements
herein are made, in the context of the foregoing.

      We call your attention to the fact that our firm only requires lawyers to
be qualified to practice law in the State of Illinois and, in rendering the
foregoing opinions, we express no opinion with respect to any laws relevant to
this opinion other than the laws and regulations identified herein.  With
respect to the opinions below that relate to the laws of the State of Maryland,
with your consent, we rely solely on the opinion of Hogan & Hartson L.L.P., a
copy of which is attached hereto as Exhibit A.

      Based upon, subject to and limited by the foregoing, we are of the opinion
that, as of the date hereof:

      1.   When the Registration Statement has become effective under
           the Securities Act of 1933, as amended (the "Act"), and when a
           series of the Preferred Shares has been classified by applicable
           Board Action, in accordance with the terms of the Declaration of
           Trust and applicable law, and appropriate Articles Supplementary
           have been filed, and, when issuance of such Preferred Shares has
           been appropriately authorized by applicable Board Action and
           following issuance of any such series of Preferred Shares against
           payment of valid consideration therefor in accordance with the terms
           of such Board Action and any applicable underwriting or purchase
           agreement, as contemplated by the Registration Statement and/or the
           applicable Prospectus Supplement, such Preferred Shares will be
           validly issued, fully paid and non-assessable under Title 8 of the
           Corporations and Associations Article of the Annotated Code of
           Maryland (the "Maryland REIT Statute").

      2.   A Deposit Agreement (when the final terms thereof have been
           duly established) substantially in the form incorporated by
           reference as Exhibit 4.3 to the Registration Statement, when duly
           authorized, executed and delivered by the Company, will constitute a
           valid and binding obligation of the Company, enforceable against the
           Company in accordance with its terms, except as may be limited by
           bankruptcy, insolvency, reorganization, moratorium or other laws
           effecting creditors' rights (including, without limitation, the
           effect of statutory and other laws regarding fraudulent conveyances,
           fraudulent transfers and preferential transfers) and as may be
           limited by the exercise of judicial discretion and the application
           of principles of equity, including, without limitation, requirements
           of good faith, fair dealing, conscionability and materiality
           (regardless of whether the Deposit Agreement is considered in a
           proceeding in equity or at law).

      3.   When the Registration Statement has become effective under
           the Act, and when a series of Preferred Shares underlying a series
           of Depositary Shares has been classified by applicable Board Action,
           in accordance with the terms of the Declaration of Trust and
           applicable law, and appropriate Articles Supplementary have been
           filed with respect to such Preferred Shares, and when issuance of
           such Preferred Shares and the execution and delivery of a Deposit
           Agreement have been appropriately authorized by applicable Board
           Action, and when the depositary receipts representing the Depositary
           Shares (the "Depositary Receipts") 


<PAGE>   4

Board of Trustees

Page 4

           in the form contemplated and authorized by a Deposit Agreement have  
           been duly executed and delivered by the Depositary against payment
           of valid consideration therefor in accordance with the terms of the
           Deposit Agreement and any applicable underwriting or purchase
           agreement, as contemplated by the Registration Statement and/or the
           applicable Prospectus Supplement, such Depositary Shares will be
           validly issued and will entitle the holders thereof to the rights
           specified in the Depositary Receipts and the Deposit Agreement for
           such Depositary Receipts.

      4.   When the Registration Statement has become effective under
           the Act, upon due authorization by Board Action of an issuance of
           Common Shares, and following issuance of any such Common Shares
           against payment of valid consideration therefor in accordance with
           the terms of such Board Action, and any applicable underwriting or
           purchase agreement as contemplated by the Registration Statement
           and/or the applicable Prospectus Supplement, such Common Shares will
           be validly issued, fully paid and non-assessable under the Maryland
           REIT Statute.

      To the extent that the obligations of the Company and the rights of any
holder of Depositary Shares under any Deposit Agreement may be dependent upon
such matters, we assume for purposes of this opinion that the applicable
Depositary is duly organized, validly existing and in good standing under the
laws of its jurisdiction of organization; that the Depositary is duly qualified
to engage in the activities contemplated by the Deposit Agreement; that the
Deposit Agreement has been duly authorized, executed and delivered by the
Depositary and constitutes a valid and binding obligation of the Depositary
enforceable against the Depositary in accordance with its terms; that the
Depositary is in compliance, with respect to acting as a Depositary under the
Deposit Agreement, with all applicable laws and regulations; and that the
Depositary has the requisite organizational and legal power and authority to
perform its obligations under the Deposit Agreement.

      The opinion expressed in Paragraph (2) above shall be understood to mean
only that if there is a default in performance of an obligation, (i) if a
failure to pay or other damage can be shown and (ii) if the defaulting party
can be brought into a court which will hear the case and apply the governing
law, then, subject to the availability of defenses and to the exceptions set
forth in Paragraph (2), the court will provide a money damage (or perhaps
injunctive or specific performance) remedy.

Ladies and Gentlemen:

We are acting as special Maryland counsel to Equity Residential Properties
Trust, a Maryland real estate investment trust (the "Company"), in connection
with its registration statement on Form S-3 (the "Registration Statement")
filed with the Securities and Exchange Commission relating to the proposed
public offering of up to $1,000,000,000 in aggregate amount of its common
shares of beneficial interest, $.01 par value (the "Common Shares"), one or
more series of its (i) preferred shares of beneficial interest, $.01 par value
(the "Preferred Shares") and (ii) depositary shares representing fractional
interests in Preferred Shares (the "Depositary Shares," and, together with the
Common Shares and Preferred Shares, the "Securities"), all of which Securities
may be offered and sold by the Company from time to time as set forth in the
prospectus which forms a part of the Registration Statement (the "Prospectus"),
and as to be set forth in one or more supplements to the Prospectus (each, a
"Prospectus Supplement").  This opinion letter is furnished to you at your
request to enable the Company to fulfill the requirements of Item 601(b)(5) of
Regulation S-K, 17 C.F.R. Section  229.601(b)(5), in connection with the
Registration Statement.
We assume that the classification, terms and conditions, amount, issuance and
sale of the Securities to be offered from time to time will be duly authorized
and determined by proper action 



<PAGE>   7

of the Board of Trustees of the Company consistent with the procedures and      
terms described in the Registration Statement (each, a "Board Action") and in
accordance with the Company's Amended and Restated Declaration of Trust (the
"Declaration of Trust"), and applicable Maryland law.  We further assume that
(i) prior to any issuance of Preferred Shares or Depositary Shares, appropriate
articles supplementary shall be filed for recordation with the Maryland State
Department of Assessments and Taxation (each, "Articles Supplementary") and
(ii) any Depositary Shares will be issued by the Depositary (as defined below)
under one or more deposit agreements (each, a "Deposit Agreement"), each to be
between the Company and a financial institution identified therein as the
depositary (each, a "Depositary"). For purposes of this opinion letter, we have
examined copies of the following documents:
1. A copy of the Registration Statement.
            2.   The Second Amended and Restated Declaration of
                 Trust, as amended, of the Company as certified by the Maryland
                 State Department of Assessments and Taxation on January 26,
                 1998 and by the Secretary of the Company on the date hereof as
                 being complete, accurate and in effect.
            3.   The Amended and Restated Bylaws of the Company,
                 as certified by the Secretary of the Company on the date
                 hereof as being complete, accurate and in effect.
            4.   Resolutions of the Board of Trustees of the
                 Company adopted on January 14, 1998 as certified by the
                 Secretary of the Company on the date hereof as being complete,
                 accurate and in effect, relating to the filing of the
                 Registration Statement and related matters.
In our examination of the aforesaid documents, we have assumed the genuineness
of all signatures, the legal capacity of all natural persons, the accuracy and
completeness of all documents submitted to us, the authenticity of all original
documents and the conformity to authentic original documents of all documents
submitted to us as copies (including telecopies).  We also have assumed the
accuracy, completeness and authenticity of the foregoing certifications of
trust officers and statements of fact, on which we are relying, and have made
no independent investigations thereof.  This opinion letter is given, and all
statements herein are made, in the context of the foregoing.
This opinion letter is based as to matters of law solely on Title 8 of the
Corporations and Associations Article of the Annotated Code of Maryland (the
"Maryland REIT Statute") and with respect to paragraph 2, Maryland contract law
(but not including any statutes, ordinances, administrative decisions, rules or
regulations of any political subdivision of the State of Maryland).  We express
no opinion herein as to any other laws, statutes, regulations, or ordinances.
            Based upon, subject to and limited by the foregoing, we are of the 
opinion that, as of the date hereof:


<PAGE>   8


           1. When the Registration Statement has become effective under the
      Securities Act of 1933, as amended (the "Act"), and when a series of the
      Preferred Shares has been classified by applicable Board Action, in
      accordance with the terms of the Declaration of Trust and applicable law,
      and appropriate Articles Supplementary have been filed, and when issuance
      of such Preferred Shares has been appropriately authorized by applicable
      Board Action and, following issuance of any such series of Preferred
      Shares against payment of valid consideration therefor in accordance with
      the terms of such Board Action and any applicable underwriting or
      purchase agreement, as contemplated by the Registration Statement and/or
      the applicable Prospectus Supplement, such Preferred Shares will be
      validly issued, fully paid and non-assessable.
           2. When the Registration Statement has become effective under the
      Act and when a series of Preferred Shares underlying a series of
      Depositary Shares has been classified by applicable Board Action, in
      accordance with the terms of the Declaration of Trust and applicable law,
      and appropriate Articles Supplementary have been filed with respect to
      such Preferred Shares, and when issuance of such Preferred Shares and the
      execution and delivery of a Deposit Agreement have been appropriately
      authorized by applicable Board Action, and when the depositary receipts
      representing the Depositary Shares (the "Depositary Receipts") in the
      form contemplated and authorized by a Deposit Agreement have been duly
      executed and delivered by the Depositary against payment of valid
      consideration therefor in accordance with the terms of the Deposit
      Agreement and any applicable underwriting or purchase agreement, as
      contemplated by the Registration Statement and/or the applicable
      Prospectus Supplement, such Depositary Shares, to the extent governed by
      Maryland law, will be validly issued.
           3. When the Registration Statement has become effective under the
      Act, upon due authorization by Board Action of an issuance of Common
      Shares, and following issuance of any such Common Shares against payment
      of valid consideration therefor in accordance with the terms of such
      Board Action and any applicable underwriting or purchase agreement, as
      contemplated by the Registration Statement and/or the applicable
      Prospectus Supplement, such Common Shares will be validly issued, fully
      paid and non-assessable.
           To the extent that the obligations of the Company and the rights of 
any holder of Depositary Shares under any Deposit Agreement may be dependent    
upon such matters, we assume for purposes of this opinion that the applicable
Depositary is duly organized, validly existing and in good standing under the
laws of its jurisdiction of organization; that the Depositary is duly qualified
to engage in the activities contemplated by the Deposit Agreement; that the
Deposit Agreement has been duly authorized, executed and delivered by the
Depositary and constitutes a valid and binding obligation of the Depositary
enforceable against the Depositary and 


<PAGE>   9

the Company in accordance with its terms; that the Depositary is in compliance,
with respect to acting as a Depositary under the Deposit Agreement, with all
applicable laws and regulations; and that the Depositary has the requisite
organizational and legal power and authority to perform its obligations under
the Deposit Agreement.
We assume no obligation to advise you of any changes in the foregoing
subsequent to the delivery of this opinion letter.  This opinion letter has
been prepared solely for your use in connection with the filing by the Company
of the Registration Statement on the date of this opinion letter and should not
be quoted in whole or in part or otherwise be referred to, nor filed with or
furnished to any governmental agency or other person or entity, without the
prior written consent of this firm.
We hereby consent to the reference to this firm under the caption "Legal
Matters" in the prospectus constituting a part of the Registration Statement.
In giving this consent, we do not thereby admit that we are an "expert" within
the meaning of the Act.

                                           Very truly yours,

                                           /s/ Hogan & Hartson L.L.P.

Board of Trustees
Equity Residential Properties Trust
Two North Riverside Plaza, Suite 400
Chicago, Illinois  60606

Ladies and Gentlemen:

                 We have acted as special tax counsel to Equity Residential
Properties Trust, a Maryland real estate investment trust (the "Company"), in
connection with its registration statement on Form S-3 (the "Registration
Statement") filed with the Securities and Exchange Commission on February 3,
1998, relating to the proposed public offering of up to $1,272,377,452 in
aggregate amount of its (i) common shares of beneficial interest, $.01 par
value (the "Common Shares"), (ii) one or more series of its preferred shares of
beneficial interest, $.01 par value (the "Preferred Shares"), (iii) depositary
shares representing fractional interests in Preferred Shares (the "Depositary
Shares," and, together with the Common Shares, and Preferred Shares, the
"Securities"), all of which Securities may be offered and sold by the Company
from time to time as set forth in the prospectus which forms a part of the
Registration Statement (the "Prospectus"), and as to be set forth in one or
more supplements to the Prospectus.  In connection with the registration of the
Preferred Shares, Common Shares and Depositary Shares, we have been asked to
provide an opinion regarding certain federal income tax matters related to the
Company.  Capitalized terms used in this letter and not otherwise defined
herein have the meaning set forth in the Registration Statement.

                 The opinion set forth in this letter is based on relevant
provisions of the Internal Revenue Code of 1986, as amended (the "Code"),
Treasury Regulations thereunder (including proposed and temporary Regulations),
and interpretations of the foregoing as expressed in court decisions, the
legislative history, and existing administrative rulings and practices of the
Internal Revenue Service (including its practices and policies in issuing
private letter rulings, which are not binding on the Internal Revenue Service
except with respect to a taxpayer that receives such a

Board of Trustees
Equity Residential Properties Trust

Page 2           

ruling), all as of the date hereof.  These provisions and interpretations are
subject to change, which may or may not be retroactive in effect, that might
result in modifications of our opinion.  Our opinion does not foreclose the
possibility of a contrary determination by the Internal Revenue Service or a
court of competent jurisdiction, or of a contrary position by the Internal
Revenue Service or the Treasury Department in regulations or rulings issued in
the future.

                 In rendering our opinion, we have examined such statutes,
regulations, records, certificates and other documents as we have considered
necessary or appropriate as a basis for such opinion, including the following:

                 (1) the Registration Statement;

                 (2) the Prospectus;

                 (3) the Second Amended and Restated Declaration of Trust of
the Company (the "Declaration of Trust") as certified by the State Department
of Assessments and Taxation of the State of Maryland (the "SDAT") on January
26, 1998 and as certified by the Secretary of the Company on the date hereof as
being complete, accurate and in effect;

                 (4) the Fourth Amended and Restated ERP Operating Limited
Partnership Agreement of Limited Partnership, dated September 30, 1995;

                 (5) the articles of incorporation, by-laws and stock ownership
information of the Management Corps.  (which term, for purposes of this opinion
letter, includes Wellsford Holly Management, Inc. and Evans Withycombe
Management, Inc.);

                 (6) the partnership agreements or limited liability company
agreements of the Management Partnerships, the Financing Partnerships, and all
other partnerships or limited liability companies in which the Operating
Partnership has an interest, including Evans Withycombe Residential, L.P.
(collectively, the partnerships in which either the Operating Partnership or
Evans Withycombe Residential, L.P. has an interest, other than the Management
Partnerships, may be referred to as the "Subsidiary Partnerships") other than

<PAGE>   3
Board of Trustees
Equity Residential Properties Trust
February 3, 1998
Page 3           


Subsidiary Partnerships formed after January 1, 1997 (for a list of the
Subsidiary Partnerships, see Exhibit A); and

                 (7) the articles of incorporation, by-laws and stock ownership
information of the QRS Corporations (for a list of the QRS Corporations, see
Exhibit B).

The opinion set forth in this letter also is premised on certain written
representations of the Company and the Operating Partnership made to us, which
relate, inter alia, to the Company and to EQR and Wellsford as predecessors by
merger to the Company.

                 In our review, we have assumed, with your consent, that all of
the representations and statements set forth in the documents we reviewed are
true and correct, and all of the obligations imposed by any such documents on
the parties thereto have been and will be performed or satisfied in accordance
with their terms.  Moreover, we have assumed that the Company, the Operating
Partnership, the Management Partnerships, the Management Corps., the QRS
Corporations and the Subsidiary Partnerships each have been and will continue
to be operated in the manner described in the relevant partnership agreement,
limited liability company agreement, articles of incorporation or other
organizational documents and in the Prospectus.  We also have assumed the
genuineness of all signatures, the proper execution of all documents, the
authenticity of all documents submitted to us as originals, the conformity to
originals of documents submitted to us as copies, and the authenticity of the
originals from which any copies were made.

                 For the purposes of our opinion, we have not made an
independent investigation of the facts set forth in the documents we reviewed.
We consequently have assumed that the information presented in such documents
or otherwise furnished to us accurately and completely describes all material
facts relevant to our opinion.  No facts have come to our attention, however,
that would cause us to question the accuracy and completeness of such facts or
documents in a material way.

                 We assume for the purposes of this opinion that the Company is
a validly organized and duly incorporated real estate investment trust under
the laws of the State of Maryland, that the Management Corps., WRP Newco and
the QRS
<PAGE>   4
Board of Trustees

Page 4


Corporations are validly organized and duly incorporated corporations under the
laws of the states in which they are incorporated, and that the Operating
Partnership, the Management Partnerships, and the Subsidiary Partnerships are
duly organized and validly existing partnerships or limited liability companies
under the laws of the states in which they are organized.

                 Based upon, and subject to, the foregoing and the next two
paragraphs below, we are of the opinion that:

                 1.       The Company was organized and has operated in
                          conformity with the requirements for qualification
                          and taxation as a REIT under the Code for its taxable
                          years ended December 31, 1992, December 31, 1993,
                          December 31, 1994, December 31, 1995, December 31,
                          1996, and December 31, 1997, and the Company's
                          current organization and method of operation should
                          enable it to continue to meet the requirements for
                          qualification and taxation as a REIT; and

                 2.       The discussion in the Prospectus under the heading
                          "Federal Income Tax Considerations," to the extent
                          that it describes matters of federal income tax law,
                          is correct in all material respects.

                 For purposes of the second opinion stated above, the term
"Prospectus" does not include the documents incorporated by reference in the
Prospectus.

                 The Company's qualification and taxation as a REIT depend upon
the Company's ability to meet on a continuing basis, through actual annual
operating and other results, the various requirements under the Code and
described in the Prospectus with regard to, among other things, the sources of
its gross income, the composition of its assets, the level of its distributions
to stockholders, and the diversity of its share ownership.  Hogan & Hartson
L.L.P. will not review the Company's compliance with these requirements on a
continuing basis.  No assurance can be given that the actual results of the
operations of the Company, the Operating Partnership, the Management
Partnerships, the Management Corps., the QRS Corporations and the Subsidiary
Partnerships, the sources of their income, the nature of their assets, the
level of the Company's distributions to shareholders
<PAGE>   5
Board of Trustees
Equity Residential Properties Trust
February 3, 1998
Page 5


and the diversity of its share ownership for any given taxable year will
satisfy the requirements under the Code for qualification and taxation as a
REIT.

                 For a discussion relating the law to the facts and the legal
analysis underlying the opinion set forth in this letter, we incorporate by
reference the discussions of federal income tax issues, which we assisted in
preparing, in the section of the Prospectus under the heading "Federal Income
Tax Considerations."  We note that the Prospectus does not necessarily address
all of the federal income tax considerations that may be relevant to a holder
of Securities, depending upon the particular form and economic terms of the
Securities when issued.  It is our understanding that in the event the Company
issues Securities, the Company will prepare an additional supplement to the
Prospectus, which supplement, together with the Prospectus, will address the
federal income tax considerations that are likely to be material to a holder of
such Securities.

                 We assume no obligation to advise you of any changes in the
foregoing subsequent to the date of this opinion letter, and we are not
undertaking to update the opinion letter from time to time.  This opinion
letter has been prepared solely for your use in connection with the filing of
the Registration Statement on the date of this opinion letter and should not be
quoted in whole or in part or otherwise be referred to, nor filed with or
furnished to any governmental agency or other person or entity, without the
prior written consent of this firm.

                 We hereby consent to the filing of this opinion as an exhibit
to the Registration Statement and to the use of the name of our firm therein.

                                        Very truly yours,

                                        /s/ Hogan & Hartson L.L.P.
