Item 1.  Business

General


     ERP Operating Limited Partnership, an Illinois limited partnership formed
in May 1993 (the "Operating Partnership"), is managed by Equity Residential
Properties Trust ("EQR"), a Maryland real estate investment trust (the
"Company"), its general partner. The Company is a self-administered and self-
managed equity real estate investment trust ("REIT"). EQR was organized in March
1993 and commenced operations on August 18, 1993 upon completion of its initial
public offering (the "EQR IPO") of 13,225,000 common shares of beneficial
interest, $0.01 par value per share ("Common Shares"). EQR was formed to
continue the multifamily residential 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 residential
properties since 1969. As used herein, the term "Company" includes EQR and those
entities owned or controlled by it, as the survivor of the mergers between EQR
and each of Wellsford Residential Property Trust ("Wellsford") (the "Wellsford
Merger") and Evans Withycombe Residential, Inc. ("EWR") (the "EWR Merger").

     The Company's subsidiaries include the Operating Partnership, Evans
Withycombe Residential, L.P. (the "EWR Operating Partnership"), Equity
Residential Properties Management Limited Partnership and Equity Residential
Properties Management Limited Partnership II (collectively, the "Management
Partnerships"), a series of partnerships (the "Financing Partnerships") and
limited liability companies ("LLCs") which beneficially own certain properties 
encumbered by mortgage indebtedness.

     As of December 31, 1997, the Operating Partnership owned or had interests
in 489 multifamily properties of which it controlled a portfolio of 463
multifamily properties (individually, a "Property" and collectively, the
"Properties") containing 135,200 units. The remaining 26 properties represent an
investment in partnership interests and subordinated mortgages collateralized by
21 properties and mortgage loans collateralized by five properties
(collectively, the "Additional Properties") containing 5,267 units. Of the 5,267
units, 1,371 units are property managed by third party unaffiliated entities.
The Operating Partnership's Properties and the Additional Properties are located
throughout the United States in the following states: Alabama, Arizona,
Arkansas, California, Colorado, Connecticut, Florida, Georgia, Idaho, Illinois,
Indiana, Iowa, Kansas, Kentucky, Maine, Maryland, Massachusetts, Michigan,
Minnesota, Missouri, Nevada, New Hampshire, New Jersey, New Mexico, North
Carolina, Ohio, Oklahoma, Oregon, South Carolina, Tennessee, Texas, Utah,
Virginia, Washington and Wisconsin. In addition, Equity Residential Properties
Management Corp. ("Management Corp.") and Equity Residential Properties
Management Corp. II ("Management Corp. II") also provide residential property
and asset management services to 29 properties containing 9,295 units owned by
affiliated entities. The Company is, together with the Operating Partnership,
one of the largest publicly traded REITs (based on the aggregate market value of
its outstanding Common Shares) and is the largest publicly traded REIT owner of
multifamily properties (based on the number of apartment units owned and total
revenues earned).

                                       4

                                    PART I
 
     Since the EQR IPO and through December 31, 1997, the Operating Partnership
has acquired direct or indirect interests in 412 properties (which included the
debt collateralized by six Properties) containing 118,510 units in the aggregate
for a total purchase price of approximately $6.5 billion, including the
assumption of approximately $1.5 billion of mortgage indebtedness. The Operating
Partnership also made an $89 million investment in partnership interests and
subordinated mortgages collateralized by 21 of the Additional Properties (its
"$89 Million Mortgage Note Investment") and an $88 million investment in
mortgage loans collateralized by five of the Additional Properties (its "$88
Million Mortgage Note Investment"). Since the EQR IPO and through December 31,
1997, the Operating Partnership has disposed of 18 properties and a portion of
one Property, containing 5,035 units, and a vacant land parcel for a total sales
price of approximately $129.8 million and the release of mortgage indebtedness
in the amount of $20.5 million.

     The Company's corporate headquarters and executive offices are located in
Chicago, Illinois. In addition, the Company has 29 management offices in the
following cities: Chicago, Illinois; Dallas, Houston and San Antonio, Texas;
Denver, Colorado; Bethesda, Maryland; Atlanta, Georgia; Las Vegas, Nevada;
Scottsdale and Tucson, Arizona; Portland, Oregon; Ypsilanti, Michigan; Charlotte
and Raleigh, North Carolina; Tampa, Jacksonville and Ft. Lauderdale, Florida;
Irvine, Pleasant Hill and Stockton, California; Kansas City, Kansas;
Minneapolis, Minnesota; Louisville, Kentucky; Tulsa, Oklahoma; Boston,
Massachusetts; Federal Way, Redmond and Seattle, Washington; and Nashville and
Memphis, Tennessee. The Company has approximately 4,200 employees. Each of the
Operating Partnership's Properties is directed by an on-site manager, who
supervises the on-site employees and is responsible for the day-to-day
operations of the Property. The manager is generally assisted by a leasing
administrator and/or property administrator. In addition, a maintenance director
at each Property supervises a maintenance staff whose responsibilities include a
variety of tasks, including responding to service requests, preparing vacant
apartments for the next resident and performing preventive maintenance
procedures year-round.

Business Objectives and Operating Strategies

     The Operating Partnership seeks to maximize both current income and long-
term growth in income, thereby increasing: (i) the value of the Properties; (ii)
distributions on a per limited partnership interest ("OP Unit") basis; and (iii)
partners' value.

     The Operating Partnership's strategies for accomplishing these objectives
are:

 . maintaining and increasing Property occupancy while increasing rental rates;

 . controlling expenses, providing regular preventive maintenance, making
  periodic renovations and enhancing amenities;

 . pursuing acquisitions that: (i) are available at prices below estimated
  replacement costs; (ii) have potential for rental rate and/or occupancy
  increases; (iii) have attractive locations in their

                                       5
<PAGE>

                                    PART I
 
  respective markets; and (iv) provide anticipated total returns that will
  increase the Operating Partnership's distributions per OP Unit.

 . purchasing newly developed as well as co-investing in the development of
  multifamily communities in the Operating Partnership's existing target markets
  where the market conditions warrant such development.

     The Operating Partnership is committed to tenant satisfaction by striving
to anticipate industry trends and implementing strategies and policies
consistent with providing quality tenant services. In addition, the Operating
Partnership continuously surveys rental rates of competing properties and
conducts satisfaction surveys of residents to determine the factors they
consider most important in choosing a particular apartment unit.

Acquisition Strategies


     The Operating Partnership anticipates that future property acquisitions
will be located in the continental United States. Management will continue to
use market information to evaluate acquisition opportunities. The Operating
Partnership's market data base allows it to review the primary economic
indicators of the markets where the Operating Partnership currently manages
Properties and where it expects to expand its operations. Acquisitions may be
financed from various sources of capital, which may include undistributed funds
from operations ("FFO"), issuances of additional equity securities by the
Company and debt securities by the Operating Partnership, sales of Properties
and collateralized and uncollateralized borrowings. In addition, the Operating
Partnership may acquire additional multifamily properties in transactions that
include the issuance of OP Units as consideration for the acquired properties.
Such transactions may, in certain circumstances, partially defer the sellers'
tax consequences.

    When evaluating potential acquisitions, the Operating Partnership will
consider: (i) the geographic area and type of community; (ii) the location,
construction quality, condition and design of the property; (iii) the current
and projected cash flow of the property and the ability to increase cash flow;
(iv) the potential for capital appreciation of the property; (v) the terms of
resident leases, including the potential for rent increases; (vi) the potential
for economic growth and the tax and regulatory environment of the community in
which the property is located; (vii) the occupancy and demand by residents for
properties of a similar type in the vicinity (the overall market and submarket);
(viii) the prospects for liquidity through sale, financing or refinancing of the
property; and (ix) competition from existing multifamily properties and the
potential for the construction of new multifamily properties in the area. The
Operating Partnership expects to purchase multifamily properties with physical
and market characteristics similar to the Properties.

Development Strategies

     The Operating Partnership seeks to acquire newly constructed properties and
make investments towards the development of properties in markets where it
discerns strong demand, which the Operating Partnership believes will enable it
to achieve superior rates of return. The Operating Partnership's current
communities under development and future developments are in

                                       6
<PAGE>

                                    PART I
 
markets or will be in markets where certain market demographics justify the
development of high quality multifamily communities. In evaluating whether to
develop an apartment community in a particular location, the Operating
Partnership analyzes relevant demographic, economic and financial data.
Specifically, the Operating Partnership considers the following factors, among
others, in determining the viability of a potential new apartment community: (i)
income levels and employment growth trends in the relevant market, (ii)
uniqueness of location, (iii) household growth and net migration of the relevant
market's population, (iv) supply/demand ratio, competitive housing alternatives,
sub-market occupancy and rent levels (v) barriers to entry that would limit
competition, and (vi) the purchase price and yields of available existing
stabilized communities, if any.

Disposition Strategies

     Management will use market information to evaluate potential dispositions.
Factors the Operating Partnership considers in deciding whether to dispose of
its Properties include the following: (i) potential increases in new
construction; (ii) areas where the economy is expected to decline substantially;
and (iii) markets where the Operating Partnership does not intend to establish
long-term concentrations. The Operating Partnership will reinvest the proceeds
received from property dispositions to fund property acquisitions. In addition,
when feasible the Operating Partnership will structure these transactions as tax
deferred exchanges.

Financing Strategies

     It is the Company's policy that EQR 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 Operating Partnership and its subsidiaries.

registered Common Shares which were sold to the public at a price of $51.125 per
share. The Company contributed to the Operating Partnership net proceeds of
approximately $24.2 million in connection with this offering (the "September
1997 Common Share Offering") in exchange for OP Units.

     In September 1997, the Company sold 11,000,000 depositary shares (the
"Series G Depositary Shares") pursuant to the August 1997 Equity Shelf
Registration. Each Series G Depositary Share represents a 1/10 fractional
interest in a 7 1/4% Series G Convertible Cumulative Preferred Share of
Beneficial Interest, $0.01 par value per share (the "Series G Preferred
Shares"). Series G Depositary Shares representing Series G Preferred Shares are
convertible at the option of the holder thereof at any time into Common Shares
at a conversion price of $58.58 per Common Share (equivalent to a conversion
rate of approximately .4268 Common Shares for each Series G Depositary Share).
The liquidation preference of each of the Series G Preferred Shares is $250.00
per share (equivalent to $25 per Series G Depositary Share). In addition, in
October 1997, the Company sold 1,650,000 additional Series G Depositary Shares
pursuant to an

over-allotment option granted to the underwriters. The Company contributed to
the Operating Partnership the net proceeds of approximately $303.6 million in
connection with this offering (the "Series G Preferred Share Offering") in
exchange for 1,265,000 of the Operating Partnership's 7 1/4% convertible
cumulative preference units (the "Series G Convertible Cumulative Preference
Units").

     In October 1997, in connection with the acquisition of a portfolio of
Properties, the Company issued 3,315,500 publicly registered Common Shares,
which were issued at a price of $45.25 per share with a value of approximately
$150 million (the "October 1997 Common Share Offering"). The Company contributed
its interest in the portfolio of Properties acquired with Common Shares to the
Operating Partnership in exchange for additional OP Units.

     On November 3, 1997, the Company filed with the SEC a Form S-3 Registration
Statement to register 7,000,000 Common Shares pursuant to a Distribution
Reinvestment and Share Purchase Plan.  This registration statement was declared
effective on November 25, 1997.  The Distribution Reinvestment and Share
Purchase Plan (the "DRIP Plan") of the Company provides holders of record and
beneficial owners of Common Shares, Preferred Shares, and limited partnership
interests in the Operating Partnership with a simple and convenient method of
investing cash distributions in additional Common Shares.  Common Shares may
also be purchased on a monthly basis with optional cash payments made by
participants in the Plan and interested new investors, not currently
shareholders of the Company, at the market price of the Common Shares less a
discount ranging between 0% and 5% (as determined in accordance with the DRIP
Plan).

     In December 1997, in connection with an acquisition of a Property, the
Company issued 736,296 publicly registered Common Shares, which were issued at a
price of $48.85 per share with a value of approximately $36 million. The Company
contributed the Property acquired with Common Shares to the Operating
Partnership in exchange for additional OP Units.

     Also in December 1997, the Company completed the sale of 467,722 publicly
registered Common Shares, which were sold at a price of $51.3125 per share.  The
Company contributed to the Operating Partnership net proceeds of approximately
$22.8 million in connection with this offering (the "December 1997 Common Share
Offering") in exchange for additional OP Units.

     During 1997, the Company issued 84,183 Common Shares pursuant to the
Employee Share Purchase Plan at net prices which ranged from $35.63 per share to
$42.08 per share and contributed to the Operating Partnership proceeds in the
amount of approximately $3.2 million in connection therewith in exchange for 
additional OP Units.

Debt Offerings For the Years Ended December 31, 1997, 1996 and 1995
- -------------------------------------------------------------------

     In April 1995, the Operating Partnership issued $125 million of 7.95%
unsecured fixed rate notes (the "2002 Notes") in a public debt offering (the
"Second Public Debt Offering"). The Operating Partnership received net proceeds
of approximately $123.1 million in connection with the Second Public Debt
Offering.

     In August 1996, the Operating Partnership issued $150 million of 7.57%
unsecured fixed rate notes (the "2026 Notes") in a public debt offering (the

Operating Partnership received net proceeds of approximately $149 million in
connection with this issuance.

     On September 18, 1996, the Operating Partnership filed with the SEC a Form
S-3 Registration Statement to register $500 million of debt securities (the
"1996 Debt Shelf Registration").


     In October 1997, the Operating Partnership issued $150 million of unsecured
fixed rate notes (the "2017 Notes") pursuant to the 1996 Debt Shelf Registration
in a public debt offering (the "October 1997 Public Debt Offering"). The 2017
Notes are due on October 15, 2017 and bear interest at 7.125%, which is payable
semiannually in arrears on April 15 and October 15, commencing April 15, 1998.
The 2017 Notes are redeemable at any time by the Operating Partnership pursuant
to the terms thereof. The Operating Partnership received net proceeds of
approximately $147.4 million in connection with this issuance.


     In November 1997, the Operating Partnership issued $200 million of
unsecured fixed rate notes pursuant to the 1996 Debt Shelf Registration in a
public debt offering (the "November 1997 Public Debt Offering"). Of the $200
million issued, $150 million of these notes are due November 15, 2001 (the "2001
Notes") and bear interest at a rate of 6.55%, which is payable semiannually in
arrears on May 15 and November 15, commencing on May 15, 1998. The remaining $50
million of these notes are due November 15, 2003 (the "2003 Notes") and bear
interest at a rate of 6.65%, which is payable semiannually in arrears on May 15
and November 15, commencing on May 15, 1998. The Operating Partnership received
net proceeds of approximately $198.5 million in connection with the 2001 Notes
and the 2003 Notes.

Credit Facility

     On November 15, 1996, the Operating Partnership completed an agreement with
Morgan Guaranty Trust Company of New York ("Morgan Guaranty") and Bank of
America Illinois ("Bank of America") to provide the Operating Partnership a $250
million unsecured line of credit. In September 1997, this agreement was amended
to increase the potential borrowings to $500 million. This line of credit
matures in November 1999 and borrowings generally will bear interest at a per
annum rate of one, two, three or six month London Interbank Offered Rate
("LIBOR"), plus a certain rate dependent upon the Operating Partnership's credit
rating, which rate is currently at 0.45%, and is subject to an annual facility
fee of $750,000. As of December 31, 1997, $235 million of borrowings were
outstanding on this line of credit, bearing interest at a weighted average rate
of 6.46%.

Business Combinations

     On May 30, 1997, the Company completed the acquisition of the multifamily
property business of Wellsford through the tax-free Wellsford Merger. The
transaction was valued at approximately $1 billion and included 72 Properties of
Wellsford containing 19,004 units which were contributed to the Operating
Partnership. The purchase price consisted of 10.8 million Common Shares issued
by the Company with a market value of $443.7 million, the liquidation value of
$157.5 million for the Wellsford Series A Cumulative Convertible Preferred
Shares of Beneficial Interest and the Wellsford Series B

Cumulative Redeemable Preferred Shares of Beneficial Interest, the assumption of
mortgage indebtedness and unsecured notes in the amount of $345 million, the
assumption of other liabilities of approximately $33.5 million and other merger
related costs of approximately $23.4 million.  In the Wellsford Merger, each
outstanding common share of beneficial interest of Wellsford was converted into
 .625 of a Common Share.  In addition, Wellsford Series A Cumulative Convertible
Preferred Shares of Beneficial Interest were redesignated as the Company's
3,999,800 Series E Cumulative Convertible Preferred Shares of Beneficial
Interest, $0.01 par value per share (the "Series E Preferred Shares") and
Wellsford's Series B Cumulative Redeemable Preferred Shares of Beneficial
Interest were redesignated as the Company's 2,300,000 9.65% Series F Cumulative
Redeemable Preferred Shares of Beneficial Interest, $0.01 par value per share
(the "Series F Preferred Shares").

     On December 23, 1997, the Company completed the acquisition of the
multifamily property business of EWR, through the tax-free EWR Merger. The
transaction was valued at approximately $1.2 billion and included 53 Properties
of EWR containing 15,331 units and three Properties under construction expected
to contain 953 units. The purchase price consisted of the Company's contribution
of the EWR Operating Partnership OP Units to the Operating Partnership at a
market value of approximately $501.6 million, issuance of approximately 2.2
million Operating Partnership OP Units in exchange for approximately 4.4 million
EWR Operating Partnership OP Units at a market value of approximately $107.3
million, the assumption of mortgage indebtedness and unsecured notes in the
amount of $498 million, the assumption of other liabilities of approximately
$28.2 million and other EWR Merger related costs of approximately $16.7 million.
In the EWR Merger, each outstanding common share of beneficial interest of EWR
was converted into .50 of a Common Share.

Recent Transactions

     From January 1, 1998 through March 13, 1998, the Operating Partnership
acquired 12 properties from unaffiliated third parties for a total purchase
price of approximately $158.2 million, which included the assumption of mortgage
indebtedness of approximately $50.8 million.  These properties were Cityscape, a
156-unit property located in St. Louis Park, Minnesota; 740 River Drive, a 162-
unit property located in St. Paul, Minnesota; Prospect Towers, a 157-unit
property located in Hackensack, New Jersey; Park Westend, a 312-unit property
located in Richmond, Virginia; Park Place, a 229-unit property located in
Houston, Texas; Emerald Bay at Winter Park, a 431-unit property located in
Winter Park, Florida; Farnham Park, a 216-unit property located in Houston,
Texas; Plantation, a 232-unit property located in Houston, Texas; Balcones Club,
a 312-unit property located in Austin, Texas; Coach Lantern, a 90-unit property
located in Scarborough, Maine; Foxcroft, a 104-unit property located in
Scarborough, Maine; and Yarmouth Woods, a 138-unit property located in Yarmouth,
Maine.

     In January 1998, the Company completed the sale of 4,000,000 publicly
registered Common Shares which were sold to the public at a price of $50.4375
per share. The Company contributed to the Operating Partnership net proceeds of
approximately $195.3 million in connection with this offering (the "January 1998
Common Share Offering") in exchange for additional OP Units.

    In February 1998, the Company completed offerings in the aggregate of
1,988,340 publicly registered Common Shares which were sold to the public at
prices ranging from $48 to $50.625 

                                       12

per share (the "February 1998 Common Share Offerings"). The Company contributed
to the Operating Partnership net proceeds of approximately $95 million 
therefrom in exchange for additional OP Units.

     Through February 1998, the Company sold approximately 639,000 Common Shares
pursuant to the DRIP Plan and contributed to the Operating Partnership proceeds
of approximately $31.7 million therefrom in exchange for additional OP Units.

     On February 3, 1998, the Company filed with the SEC a Form S-3 Registration
Statement to register $1 billion of equity securities.  The SEC declared this
registration statement effective on February 27, 1998.

     On February 3, 1998, the Operating Partnership filed a Form S-3
Registration Statement to register $1 billion of debt securities.  The SEC
declared this registration statement effective on February 27, 1998.

     On March 12, 1998, the Operating Partnership disposed of two Properties for
a total sales price of $16.7 million.

Competition

     All of the Properties are located in developed areas that include other
multifamily properties.  The number of competitive multifamily properties in a
particular area could have a material effect on the Operating Partnership's
ability to lease units at the Properties or at any newly acquired properties and
on the rents charged.  The Operating Partnership may be competing with other
entities that have greater resources than the Operating Partnership and whose
managers have more experience than the Operating Partnership's officers and
trustees.  In addition, other forms of multifamily properties, including
multifamily properties and manufactured housing controlled by Mr. Zell, and
single-family housing, provide housing alternatives to potential residents of
multifamily properties.

Risk Factors

     The Operating Partnership's results of operations are subject to certain
risks and uncertainties relating to the operations of its Properties.  Investors
should carefully consider, among other factors, the matters described below
prior to making an investment decision regarding the securities of the Operating
Partnership.

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 Operating
Partnership's total debt equaled approximately $2.9 billion.  Of the total debt
outstanding, $912.7 million, including the line of credit balance of $235
million, represented floating rate debt, of which approximately $611 million was
issued at tax exempt rates.  In addition, from June 1995 through October 1997,
the Company issued Preferred Shares and Depositary Shares pursuant to offerings
previously mentioned and utilized the proceeds to repay indebtedness and to
acquire additional Properties.  The Operating Partnership is subject to 

                                       13
<PAGE>

                                    PART I


the risks normally associated with debt or preferred equity financing, including
the risk that the Operating Partnership'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 Operating Partnership were
unable to refinance its indebtedness on acceptable terms, or at all, the
Operating Partnership might be forced to dispose of one or more of the
Properties on disadvantageous terms, which might result in losses to the
Operating Partnership and might adversely affect the cash available to meet
required payments of principal and interest and for distributions to
unitholders. If interest rates or other factors at the time of the refinancing
result in higher interest rates upon refinancing, the Operating Partnership's
interest expense would increase, which would affect the Operating Partnership's
ability to meet required payments of principal and interest and to make
distributions to its unitholders. Furthermore, if a Property is mortgaged to
secure payment of indebtedness and the Operating Partnership 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 Operating
Partnership. 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 Operating Partnership's Activities. A substantial
portion of the Operating Partnership's debt has been issued pursuant to certain
indentures (the "Indentures") which restrict the amount of indebtedness
(including acquisition financing) the Operating Partnership may incur.
Accordingly, if the Company or the Operating Partnership is unable to raise
additional equity or borrow money, respectively, because of the debt
restrictions in the Indentures, the Operating Partnership's ability to acquire
additional properties may be limited. If the Operating Partnership is unable to
acquire additional properties, its ability to increase funds from operations,
and thereby cash available to meet required payments of principal and interest,
will be limited to increasing funds from operations of the existing Properties
in the Operating Partnership's portfolio at such time.

     Bond Compliance Requirements.  Certain of the Operating Partnership'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 Operating Partnership 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 Operating
Partnership's income from these Properties if the Operating Partnership is
required to lower its rental rates to attract low or moderate income tenants, or
eligible/qualified tenants.

Potential Environmental Liability Affecting the Operating Partnership

     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

                                      14

<PAGE>

                                    PART I

 
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 Operating
Partnership 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 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
Operating Partnership of each of the Properties. These environmental assessments
have not revealed, nor is the Operating Partnership aware of, any environmental
liability that the Operating Partnership's management believes would have a
material adverse effect on the Operating Partnership'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 Operating Partnership, 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
Operating Partnership's resulting ability to make expected interest payments on
debt securities 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 Operating
Partnership to provide adequate maintenance and insurance, and increased
operating costs (including insurance premiums and real estate taxes). The
Operating Partnership's income would also be adversely affected if tenants were
unable to pay rent or the Operating Partnership were unable to rent apartment
units on favorable terms. If the Operating Partnership were unable to promptly
relet 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 Operating Partnership's income and ability to meet
required payments of principal and interest and to make expected distributions
to unitholders may be adversely affected. In addition, certain expenditures
associated with each equity investment

                                      15

<PAGE>

                                    PART I

 
(such as real estate taxes and maintenance costs) generally are not reduced when
circumstances cause a reduction in income from the investment. The Operating
Partnership intends to purchase newly developed, as well as invest in the 
development of multifamily communities. Such projects generally require the
expenditure of capital, and consequently there can be no assurance that any of
such projects will be completed or that such projects will prove to be
profitable. The failure of the Operating Partnership to complete or to
profitably operate planned development projects may have an adverse affect on
the Operating Partnership's results of operations and financial position.
Furthermore, real estate investments are relatively illiquid and, therefore,
will tend to limit the ability of the Operating Partnership 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 Operating Partnership's cash provided by operations
and its ability to make interest payments on debt securities. 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 Operating Partnership's income and its ability to make interest
payments on debt securities.

Dependence on Key Personnel

     The Operating Partnership is dependent on the efforts of the Company's
executive officers.  While the Operating Partnership 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 Operating Partnership. Only
one of these officers has entered into an employment agreement with the Company.

Distribution Requirements Potentially Increasing Indebtedness of the Operating 
Partnership

     The Operating Partnership 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 Operating
Partnership 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 Operating Partnership
could be required to borrow funds or liquidate investments on adverse terms in
order to allow the Company to meet such distribution requirements.

Item 2.  The Properties

     As of December 31, 1997, the Operating Partnership controlled a portfolio
of 463 multifamily properties located in 34 states containing 135,200 apartment
units. The average number of units per Property was approximately 293. The units
are typically contained in a series of two-story buildings. The Properties
contain an aggregate of approximately 118.9 million rentable square feet, with
an average unit size of 886 square feet. The average rent per unit was $696, and
the average rent per square foot was $0.79.


     As of December 31, 1997, the Properties had an average occupancy rate of
95%. Tenant leases are generally year-to-year and require security deposits. The
Properties typically provide residents with attractive amenities, which may
include a clubhouse, swimming pool, laundry facilities and cable television
access. Certain Properties offer additional amenities such as saunas,
whirlpools, spas, sports courts and exercise rooms.

                                      16

<PAGE>

                                    PART I

 
     The Operating Partnership believes that the Properties provide amenities
and common facilities that create an attractive residence for tenants. It is
management's role to monitor compliance with Property policies and to provide
preventive maintenance of the Properties including common areas, facilities and
amenities. The Operating Partnership holds periodic meetings of its Property
management personnel for training and implementation of the Operating
Partnership's strategies. The Operating Partnership believes that, due in part
to this strategy, the Properties historically have had high occupancy rates.

     The distribution of the Properties throughout the United States reflects
the Operating Partnership's belief that geographic diversification helps
insulate the portfolio from regional and economic influences. At the same time,
the Operating Partnership has sought to create clusters of Properties within
each of its primary markets in order to achieve economies of scale in management
and operation; however, the Operating Partnership may acquire additional
multifamily properties located anywhere in the United States.

     The Operating Partnership beneficially owns fee simple title to 456 of the
Properties and holds a 73-year leasehold interest with respect to one Property
(Mallgate). Direct fee simple title for certain of the Properties is owned by
single-purpose nominee corporations or land trusts that engage in no business
other than holding title to the Property for the Operating Partnership. Holding
title in such a manner is expected to make it less costly to transfer such
Property in the future in the event of a sale and should facilitate financing
since lenders often require title to a Property to be held in a single purpose
entity in order to isolate that Property from potential liabilities of other
Properties. Direct fee simple title for certain other Properties is owned by an
LLC. In addition, with respect to two Properties, the Operating Partnership owns
the debt collateralized by such Properties and with respect to four Properties,
the Operating Partnership owns an interest in the debt collateralized by the
properties.

     As of December 31, 1997, the Operating Partnership had an investment in
partnership interests and subordinated mortgages and mortgage loans
collateralized by the Additional Properties. The Additional Properties contain
5,267 units, located in seven states.

     The following two tables set forth certain information relating to the
Properties and the Additional Properties:

Item 3.  Legal Proceedings

     Richard M. Perlman, a former employee of companies controlled by Mr. Zell,
filed a legal proceeding against Mr. Zell and various partnerships and
corporations controlled by Mr. Zell claiming, inter alia, that he had an
                                              ----------
interest in 20 of 46 of the initial properties (the "Zell Properties") and that
he suffered damages when those Properties were transferred into the REIT. The
proceeding was filed on July 21, 1995 (Richard M. Perlman, et al. v. Samuel
                                       ------------------------------------
Zell, et al.) (United States District Court for the Northern District of
- ------------
Illinois-Eastern Division, Case No. 95 C 4242). The Company and the Operating
Partnership were not parties to this lawsuit. This action has proceeded to a
jury verdict and the Company has incurred no liability and will incur no losses
in connection with such action.

     In addition, only ordinary routine litigation incidental to the business
which is not deemed material was initiated during the year ended December 31,
1997. The Operating Partnership does not believe there is any other litigation,
except as mentioned in the previous paragraph, threatened against the Operating
Partnership other than routine litigation arising out of the ordinary course of
business, some of which is expected to be covered by liability insurance, none
of which is expected to have a material adverse effect on the consolidated
financial statements of the Operating Partnership.

Item 4.  Submission of Matters to a Vote of Security Holders

     None.

Item 6.   Selected Financial Data (Consolidated and Combined Historical
(continued))

(1)  Historical results for the year ended December 31, 1993 included combined
results of EQR's Predecessor Business for the period January 1, 1993 through
August 17, 1993.

(2)  Includes approximately $36 million of construction in progress as of
December 31, 1997.

(3)  In August 1995, the Operating Partnership also made an $89 million Mortgage
Note Investment collateralized by 21 of the Additional Properties. In addition,
in April 1997, the Operating Partnership made its $88 Million Mortgage Note
Investment collateralized by five of the Additional Properties. The Additional
Properties consist of 5,267 units.
 
(4)  The Operating Partnership generally considers funds from operations
("FFO")to be one measure of the performance of real estate companies. The new
definition of FFO adopted in March 1995 by the Board of Governors of the
National Association of Real Estate Investment Trusts ("NAREIT") defines FFO as
net income (loss) (computed in accordance with generally accepted accounting
principles ("GAAP")), excluding gains (or losses) from debt restructuring and
sales of property, plus depreciation on real estate assets, and after
adjustments for unconsolidated partnerships and joint ventures. Adjustments for
unconsolidated partnerships and joint ventures are calculated to reflect FFO on
the same basis. The Operating Partnership believes that FFO is helpful to
investors as a measure of the performance of a real estate company because,
along with cash flows from operating activities, financing activities and
investing activities, it provides investors an understanding of the ability of
the Operating Partnership to incur and service debt and to make capital
expenditures. FFO does not represent cash generated from operating activities in
accordance with GAAP and therefore should not be considered an alternative to
net income as an indication of the Operating Partnership's performance or to net
cash flows from operating activities as determined by GAAP as a measure of
liquidity and is not necessarily indicative of cash available to fund cash
needs. The Operating Partnership's calculation of FFO represents net income,
excluding gains on dispositions of properties, gains on early extinguishment of
debt, and write-off of unamortized costs on refinanced debt, less an allocation
of net income to preference unit holders, plus depreciation on real estate
assets and amortization of deferred financing costs related to EQR's Predecessor
Business. The Operating Partnership's calculation of FFO may differ from the
methodology for calculating FFO utilized by other companies and, accordingly,
may not be comparable to such other companies. The Operating Partnership's
calculation of FFO for 1995 and 1994 have been restated to reflect the effects
of the new definition as mentioned above. FFO for the year ended December 31,
1994 includes the effect of a one-time charge of approximately $879,000 for the
relocation of the property management headquarters to Chicago. In addition, FFO
for the year ended December 31, 1993 excludes the effect of refinancing costs of
approximately $3.3 million which represented costs associated with the
prepayment of certain mortgage loans.

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

     The following discussion and analysis of the results of operations and
financial condition of the Operating Partnership should be read in conjunction
with "Selected Financial Data" and the historical Consolidated Financial
Statements thereto appearing elsewhere in this Form 10-K. Due to the Operating
Partnership's ability to control the EWR Operating Partnership, the Management
Partnerships, the Financing Partnerships and the LLCs, each entity has been
consolidated with the Operating Partnership for financial reporting purposes.

     Forward-looking statements in this report are made pursuant to the safe
harbor provisions of the Private Securities Litigation Reform Act of 1995.  The
words "believes", "expects" and "anticipates" and other similar expressions
which are predictions of or indicate future events and trends and which do not
relate solely to historical matters, identify forward-looking statements.  Such
forward-looking statements are subject to risks and uncertainties, which could
cause actual results, performance, or achievements of the Operating Partnership
to differ materially from anticipated future results, performance or
achievements expressed or implied by such forward-looking statements.  Factors
that might cause such differences include, but are not limited to, the
following:  the alternative sources of capital to the Operating Partnership are
too high; occupancy levels and market rents may be adversely affected by local
economic and market conditions, which are beyond the Operating Partnership's
control; and additional factors as discussed in Part I of the Annual Report as
filed on Form 10-K.  Readers are cautioned not to place undue reliance on these
forward-looking statements, which speak only as of the date hereof.  The
Operating Partnership undertakes no obligation to publicly release any revisions
to these forward-looking statements, which may be made to reflect events or
circumstances after the date hereof or to reflect the occurrence of
unanticipated events.

Results of Operations

     Since the EQR IPO and through December 31, 1997, the Operating
Partnership has acquired direct or indirect interests in 412 properties (the
"Acquired Properties"), containing 118,510 units in the aggregate for a total
purchase price of approximately $6.5 billion, including the assumption of
approximately $1.5 billion of mortgage indebtedness and $0.4 billion of
unsecured notes. The Operating Partnership's interest in six of the Acquired
Properties at the time of acquisition thereof consisted solely of ownership of
the debt collateralized by such Acquired Properties. The Operating Partnership
purchased ten of such Acquired Properties or 2,694 units between the IPO and
December 31, 1993 (the "1993 Acquired Properties"); 84 of such Acquired
Properties or 26,285 units in 1994 (the "1994 Acquired Properties"); 17 of such
Acquired Properties or 5,035 units in 1995 (the "1995 Acquired Properties"); 49
of such Acquired Properties consisting of 15,665 units in 1996 (the "1996
Acquired Properties"); and 252 of such Acquired Properties consisting of 68,830
units in 1997 (the "1997 Acquired Properties"), which include the Properties
acquired in connection with the Wellsford Merger and the EWR Merger
(collectively, the "Mergers"). The Acquired Properties are presented in the
Consolidated and Combined Financial Statements of the Operating Partnership from
the date of each acquisition or the closing dates of the Mergers. In addition,
in August 1995 the Operating Partnership made its $89 Million Note Investment
collateralized by 21 of the

Additional Properties. Also in April 1997, the Operating Partnership made its
$88 Million Mortgage Note Investment collateralized by five of the Additional
Properties.

     During 1995 the Operating Partnership disposed of six properties containing
2,445 units (the "1995 Disposed Properties"). During 1996, the Operating
Partnership disposed of five properties containing 1,254 units (the "1996
Disposed Properties"). During 1997 the Operating Partnership disposed of seven
properties, a portion of one property and a vacant land parcel containing 1,336
units (the "1997 Disposed Properties").

     The Operating Partnership's overall results of operations for the three
years ended December 31, 1997 have been significantly impacted by the Operating
Partnership's acquisition activity. The significant changes in rental revenues,
property and maintenance expenses, real estate taxes and insurance, depreciation
expense, property management and interest expense can all primarily be
attributed to the acquisition of the Acquired Properties. The impact of the
Acquired Properties is discussed in greater detail in the following paragraphs.

     Properties that the Operating Partnership owned for all of both 1997 and
1996 representing 49,805 units (the "1997 Same Store Properties") and Properties
that the Operating Partnership owned for all of both 1996 and 1995 representing
45,699 units (the "1996 Same Store Properties") also impacted the Operating
Partnership's results of operations and are discussed as well in the following
paragraphs.

     Comparison of the year ended December 31, 1997 to the year ended 
     December 31, 1996

     For the year ended December 31, 1997, income before gain on disposition of
properties and extraordinary items increased by $79 million when compared to the
year ended December 31, 1996. This increase was primarily due to increases in
rental revenues net of increases in property and maintenance expenses, real
estate taxes and insurance, property management expenses, depreciation, interest
expense and general and administrative expenses. All of the increases in the
various line item accounts mentioned above can be primarily attributed to the
1997 Acquired Properties and 1996 Acquired Properties. These increases were
partially offset by the 1997 Disposed Properties and the 1996 Disposed
Properties. The increase in interest income of $7.5 million earned on the
Operating Partnership's mortgage note investments is primarily attributable to
its $88 Million Mortgage Note Investment as well as an increase in interest
income earned on its $89 Million Mortgage Note Investment.

     In regard to the 1997 Same Store Properties, rental revenues increased by
approximately $11.9 million or 3.1% primarily as a result of higher rental rates
charged to new tenants and tenant renewals and higher average occupancy levels.
Overall property operating expenses which include property and maintenance, real
estate taxes and insurance and an allocation of property management expenses
decreased approximately $1.5 million or 0.9%. This decrease was primarily the
result of lower medical and health care insurance costs, which resulted in lower
payroll costs.

                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Results of Operations (Continued)
 
In addition, the Operating Partnership was also successful in reducing its costs
for leasing and advertising as well as building, maintenance and grounds costs
by consolidating its vendor services in selected submarkets in order to obtain
volume discounts and by consolidating its personnel in selected submarkets where
Properties were centrally located. With respect to the lower medical and health
care insurance costs, the Operating Partnership believes this is not a
sustainable trend but only benefited the 1997 results.

     Property management represents expenses associated with the management of
the Operating Partnership's Properties. These expenses increased by
approximately $9.3 million primarily due to the continued expansion of the
Operating Partnership's property management business to facilitate the
management of the Operating Partnership's additional properties. During 1997,
the Operating Partnership opened new management offices in Houston, Texas;
Ypsilanti, Michigan; Kansas City, Kansas City; Irvine, California; Minneapolis,
Minnesota; Charlotte, North Carolina; and Louisville, Kentucky. In addition, the
Operating Partnership assumed a management office in Tulsa, Oklahoma, related to
the Wellsford Merger and significantly expanded a management office in
Scottsdale, Arizona related to the EWR Merger.

     Fee and asset management revenues and fee and asset management expenses are
associated with the management of properties not owned by the Operating
Partnership that are managed for affiliates. These revenues decreased by $0.5
million primarily due to the disposition of certain of these properties,
resulting in the Operating Partnership no longer providing fee and asset
management services to such properties.

     Interest expense, including amortization of deferred financing costs,
increased by approximately $38.3 million. This increase was primarily the result
of an increase in the Operating Partnership's average indebtedness outstanding
which increased by $564.5 million, primarily due to the Wellsford Merger.
However, the Operating Partnership's effective interest costs decreased from
7.87% in 1996 to 7.5% in 1997.

     General and administrative expenses, which include corporate operating
expenses, increased approximately $5.2 million between the years under
comparison. This increase was primarily due to adding corporate personnel,
higher salary costs and shareholder reporting costs as well as an increase in
professional fees. General and administrative expenses as a percentage of total
revenues were 2.02% for the year ended December 31, 1997, which was a slight
decrease from 2.06% in 1996.

Comparison of the year ended December 31, 1996 to the year ended December 31,
1995

     For the year ended December 31, 1996, income before gain on disposition of
properties and extraordinary items increased by $37.3 million when compared to
the year ended December 31, 1995. This increase was primarily due to increases
in rental revenues net of increases in property and maintenance expenses, real
estate taxes and insurance, property management expenses,

depreciation, interest expense and general and administrative expenses. All of
the increases in the various line item accounts mentioned above can be primarily
attributed to the 1996 Acquired Properties and 1995 Acquired Properties. These
increases were partially offset by the 1996 Disposed Properties and the 1995
Disposed Properties. Interest income earned on the Company's mortgage note
investment increased by approximately $8 million and was an additional factor
that impacted the year to year change.

     In regard to the 1996 Same Store Properties, rental revenues increased by
approximately $15.9 million or 4.8% primarily as a result of higher rental rates
charged to new tenants and tenant renewals and higher average occupancy levels.
Overall property operating expenses which include property and maintenance, real
estate taxes and insurance and an allocation of property management expenses
increased approximately $1.7 million or 1.2%. This increase was primarily the
result of higher payroll expenses and utilities costs. For 1996 the Operating
Partnership also increased its per unit charge for property level insurance
which increased insurance expense by approximately $0.7 million. In addition,
real estate taxes increased due to reassessments on certain of the 1996 Same
Store Properties.

     Property management represents expenses associated with the management of
the Operating Partnership's Properties. These expenses increased by
approximately $2.3 million primarily as a result of the expansion of the
Operating Partnership's property management business with the addition of a
management office in Seattle, Washington and during the third quarter of 1996
the addition of two new management offices located in Raleigh, North Carolina
and Ft. Lauderdale, Florida. Other factors that impacted this increase were
higher payroll and travel costs and legal and professional fees.

     Fee and asset management revenues and fee and asset management expenses are
associated with the management of properties not owned by the Operating
Partnership that are managed for affiliates. These revenues decreased by $0.3
million primarily due to the disposition of certain of these properties.

     Interest expense, including amortization of deferred financing costs,
increased by approximately $3.8 million. This increase was primarily the result
of an increase in the Operating Partnership's average indebtedness outstanding
which increased by $75.8 million. However, the Operating Partnership's effective
interest costs decreased from 8.09% in 1995 to 7.87% in 1996.

     General and administrative expenses, which include corporate operating
expenses, increased approximately $1.7 million between the years under
comparison. This increase was primarily due to adding corporate personnel,
higher salary costs and shareholder reporting costs as well as an increase in
professional fees. General and administrative expenses as a percentage of total
revenues were 2.06% for the year ended December 31, 1996, which was a slight
decrease from 2.08% in 1995.

For the Year Ended December 31, 1997

     As of January 1, 1997, the Operating Partnership had approximately $147.3
million of cash and cash equivalents and $250 million available on its line of
credit. After taking into effect the various transactions discussed in the
following paragraphs, cash and cash equivalents at December 31, 1997 was
approximately $33.3 million and the amounts available on the Operating
Partnership's line of credit were $265 million, of which $24.7 million is
restricted. In addition, the Operating Partnership had $6.6 million of proceeds
from a property sale included in deposits-restricted. The following discussion
also explains the changes in net cash provided by operating activities, net cash
(used for) investing activities and net cash provided by financing activities,
all of which are presented in the Operating Partnership's Consolidated
Statements of Cash Flows.

     Part of the Operating Partnership's strategy in funding the purchase of
multifamily properties excluding those Properties acquired through the Mergers,
is to utilize its line of credit and to subsequently repay the line of credit
from the issuance of additional equity or debt securities. Continuing to employ
this strategy, during 1997 the Company and/or the Operating Partnership; (i)
issued a total of approximately 11.9 million Common Shares through various
offerings, other than issuances in connection with the acquisitions of
Properties and received total net proceeds of approximately $536.8 million, (ii)
completed the offerings of the Series D Preferred Shares and Series G Preferred
Shares and received net proceeds of approximately $473.1 million and (iii)
issued the 2017 Notes, the 2001 Notes and the 2003 Notes and received net
proceeds of approximately $345.9 million. All of these proceeds have been or
will be utilized to purchase additional properties and/or repay the line of
credit and mortgage indebtedness on certain Properties.

     With respect to Property acquisitions during the year, including the
effects of the Mergers, the Operating Partnership purchased 252 Properties
containing 68,830 units for a total purchase price of approximately $4.1
billion, including the issuances of 25.1 million of Common Shares, the
assumption of EWR's minority interest with a market value of approximately
$107.3 million, the liquidation value of $157.5 million for the Series E
Preferred Shares and Series F Preferred Shares, the assumption of mortgage
indebtedness and unsecured notes of approximately $1.3 billion and issuance of
OP Units with a value of approximately $5.3 million. The cash portion of these
acquisitions were primarily funded from amounts drawn on the Operating
Partnership's line of credit and proceeds received in connection with the
transactions mentioned in the previous paragraph.

     During the year ended December 31, 1997, the Operating Partnership also
disposed of seven properties, a portion of one Property and a vacant land parcel
which generated net proceeds of approximately $35.8 million. Proceeds from the
dispositions were ultimately applied to purchase additional Properties.

Liquidity and Capital Resources (Continued)
 
     As of December 31, 1997, the Operating Partnership had total indebtedness
of approximately $2.9 billion, which included mortgage indebtedness of $1.6
billion (including premiums of $3.9 million), of which $723 million represented
tax exempt bond indebtedness, and unsecured debt of $1.4 billion (including net
discounts and premiums in the amount of $5.7 million). During the year, the
Operating Partnership repaid an aggregate of $113.4 million of mortgage
indebtedness on 29 of its Properties. In addition, unsecured floating rate notes
in the amount of $100 million were repaid at maturity on December 22, 1997.
These repayments were funded from the Operating Partnership's line of credit or
from proceeds received from the various capital transactions mentioned in
previous paragraphs.

     The Operating Partnership has, from time to time, entered into interest
rate protection agreements (financial instruments) to reduce the potential
impact of increases in interest rates but has limited exposure to the extent of
non-performance by the counterparties of each protection agreement since each
counterparty is a major U.S. financial institution, and the Operating
Partnership does not anticipate their non-performance. No such financial
instrument has been used for trading purposes. In February 1996, the Operating
Partnership entered into two interest rate protection agreements that were
intended to hedge the Operating Partnership's interest rate risk at maturity of
$175 million of indebtedness. The first agreement hedged the interest rate risk
of $50 million of mortgage loans scheduled to mature in September 1997 by
locking the five year Treasury Rate, commencing October 1, 1997. This agreement
was cancelled in July 1997, at no cost to the Operating Partnership, in
conjunction with a new interest rate agreement discussed below. The second
agreement hedged the interest rate risk of $125 million of unsecured senior
notes issued in 1994 by the Operating Partnership by locking the four year
Treasury Rate commencing May 15, 1999. There was no current cost to the
Operating Partnership for entering into these agreements. In July 1997, the
Operating Partnership entered into two interest rate protection agreements to
effectively fix the interest rate cost of the Operating Partnership's 2001 Notes
and 2003 Notes. One agreement was for a notional amount of $100 million with a
locked in treasury rate at 6.134%. The second agreement was for a notional
amount of $75 million with a locked in treasury rate of 6.287%. The fair value
of these instruments as of December 31, 1997 approximated their carrying or
contract values.

     The Operating Partnership has a policy of capitalizing expenditures made
for new assets, including newly acquired properties and the costs associated
with placing these assets into service. Expenditures for improvements and
renovations that significantly enhance the value of existing assets or
substantially extend the useful life of an asset are also capitalized. Capital
spent for replacement-type items such as appliances, draperies, carpeting and
floor coverings, mechanical equipment and certain furniture and fixtures is also
capitalized. Expenditures for ordinary maintenance and repairs are expensed to
operations as incurred. With respect to acquired properties, the Operating
Partnership has determined that it generally spends $1,000 per unit during its
first three years of ownership to fully improve and enhance these properties to
meet the Operating Partnership's standards. In regard to capital replacements,
the Operating Partnership generally expects to spend $300 per unit on an annual
recurring basis.

Liquidity and Capital Resources (Continued)

     During the year ended December 31, 1997, total capital expenditures for the
Operating Partnership approximated $60 million. Of this amount, approximately
$9.5 million related to capital improvements and major repairs for certain of
the 1995, 1996 and 1997 Acquired Properties. Capital improvements and major
repairs for all of the Operating Partnership's pre-EQR IPO properties and
certain Acquired Properties approximated $19.4 million, or $217 per unit.
Capital spent for replacement-type items approximated $21.4 million, or $239 per
unit, which is in line with the Operating Partnership's expected annual
recurring per unit cost. Also included in total capital expenditures was $9.7
million expended for non-real estate additions such as computer software,
computer equipment, furniture and fixtures and leasehold improvements for the
Operating Partnership's property management offices and its corporate
headquarters. Such capital expenditures were primarily funded from working
capital reserves and from net cash provided by operating activities. Total
capital expenditures for 1998 are budgeted to be approximately $94.5 million,
which includes approximately $29.7 million related to capital improvements and
major repairs for certain of the 1995, 1996 and 1997 Acquired Properties.

     Total distributions paid in 1997 amounted to $292.1 million, which included
the distribution declared in the fourth quarter of 1996. The fourth quarter of
1997 distributions to OP Unit holders were paid on December 30, 1997. On March
2, 1998, the Operating Partnership declared a $0.67 distribution per OP Unit
payable to holders of record on March 27, 1998. The OP Unit distribution will be
paid on April 10, 1998. Also, on March 2, 1998, the Operating Partnership
declared a $0.585938 distribution, a $0.570313 distribution, a $0.570313
distribution, a $0.5375 distribution, a $0.603125 distribution and a $0.453125
distribution to the Company as holder of the Series A Cumulative Redeemable
Preference Units, the Series B Cumulative Redeemable Preference Units, the
Series C Cumulative Redeemable Preference Units, the Series D Cumulative
Redeemable Preference Units, the Series F Cumulative Redeemable Preference Units
and the Series G Convertible Cumulative Preference Units, respectively, payable
to holders of record on March 27, 1998. These distributions will be paid on
April 15, 1998. In addition, the Operating Partnership declared on March 2,
1998, a $0.4375 distribution to the Company as holder of the Series E Cumulative
Convertible Preference Units. This distribution will be paid on April 1, 1998.
 
     Subsequent to December 31, 1997, the Operating Partnership acquired 12
additional properties representing 2,539 units for a total purchase price of
approximately $158.2 million, including the assumption of approximately $50.8
million of mortgage indebtedness. These acquisitions were funded from proceeds
of the January 1998 Common Share Offering. The Operating Partnership is actively
seeking to acquire additional multifamily properties with physical and market
characteristics similar to the Properties. During the remainder of 1998, the
Operating Partnership expects to acquire between 10,000 to 15,000 multifamily
units. However, there is no assurance that this level of property acquisitions
can be achieved.

                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Liquidity and Capital Resources (Continued)
 
     In January 1998, the Company contributed to the Operating Partnership net
proceeds of $195.3 million from the January 1998 Common Share Offering. These
proceeds were utilized to repay a portion on the line of credit, to purchase
additional properties and/or repay mortgage indebtedness on one Property.

     In February 1998, the Company contributed to the Operating Partnership net
proceeds of $95 million from the February 1998 Common Share Offerings. These net
proceeds were utilized to repay the remaining balance outstanding on the line of
credit and to purchase additional properties.

     Through February 1998, the Company contributed to the Operating Partnership
net proceeds of $31.7 million from the DRIP Plan.

     The Operating Partnership anticipates that it may sell certain Properties
in the portfolio and may sell up to 2,500 multifamily units during 1998.
However, there is no assurance that this level of property dispositions may be
achieved.

     In March 1998, the Operating Partnership disposed of two Properties for a
total sales price of $16.7 million. These proceeds will be utilized to purchase
additional Properties.

     The Operating Partnership expects to meet its short-term liquidity
requirements, including capital expenditures relating to maintaining its
existing Properties, generally through its working capital, net cash provided by
operating activities and borrowings under its line of credit. The Operating
Partnership considers its cash provided by operating activities to be adequate
to meet operating requirements and payments of distributions. The Operating
Partnership also expects to meet its long-term liquidity requirements, such as
scheduled mortgage debt maturities, reduction of outstanding amounts under its
line of credit, property acquisitions, financing of construction and development
activities and capital improvements through the issuance of unsecured notes and
equity securities including additional OP Units as well as from undistributed
FFO and proceeds received from the disposition of certain Properties. In
addition, the Operating Partnership has certain uncollateralized Properties
available for additional mortgage borrowings in the event that the public
capital markets are unavailable to the Operating Partnership or the cost of
alternative sources of capital to the Operating Partnership is too high.

     In November 1996, the Operating Partnership reached an agreement with
Morgan Guaranty and Bank of America to provide the Operating Partnership a new
credit facility with potential borrowings of up to $250 million. In September
1997, this agreement was amended whereby the potential borrowings were increased
to $500 million. This line of credit matures in November 1999 and will continue
to be used for property acquisitions and for any working capital needs. As of
March 13, 1998, no amounts were outstanding under this facility.

     In connection with the Wellsford Merger, the Operating Partnership has
provided a standby obligation in the amount of $30 million pursuant to an
agreement entered into with Wellsford Real Properties, Inc., a Maryland
corporation ("WRP"), for the construction financing for a multifamily
development project located in Denver, Colorado. In addition, the Operating
Partnership has provided a $14.8 million credit enhancement with respect to
bonds issued to finance certain public improvements at the multifamily
development project.

     In December 1997, the Operating Partnership entered into a joint venture
agreement with a multifamily residential real estate developer whereby the
Operating Partnership will make investments in a limited partnership to fund its
portion of the project cost. As of December 31, 1997, the Operating Partnership
funded approximately $6.9 million in connection with this agreement. In
addition, the Operating Partnership also funded $20 million to guarantee third
party construction financing and will be obligated to fund an additional $20
million in 1998. Subsequent to December 31, 1997, the Operating Partnership has
also funded approximately $9.9 million and anticipates to fund up to an
additional $85 million in 1998.

     The Operating Partnership has conducted a review of its computer operating
systems and has identified those areas that could be affected by the "Year 2000"
issue and has developed a plan to resolve this issue. The Operating Partnership
believes that by modifying certain existing hardware and software and, in other
cases, converting to new application systems, the Year 2000 problem can be
resolved without significant operational difficulties. The Operating Partnership
has initiated formal communications with all of its significant suppliers to
determine the extent to which the Operating Partnership's interface systems are
vulnerable to those third parties' failure to remediate their own Year 2000
issues. The Operating Partnership has also identified the cost of the Year 2000
issue and does not expect the financial impact to be material to the Operating
Partnership's results of operations or financial position.

For the Year Ended December 31, 1996

     As of January 1, 1996, the Operating Partnership had approximately $13.4
million of cash and cash equivalents and $158 million available on its line of
credit. After taking into effect the various transactions discussed in the
following paragraphs, cash and cash equivalents at December 31, 1996 was
approximately $147.3 million and the amounts available on the Operating
Partnership's line of credit were $250 million. In addition, the Operating
Partnership had $3.6 million of proceeds from a property sale included in
deposits-restricted. The following discussion also explains the changes in net
cash provided by operating activities, net cash (used for) investing activities
and net cash provided by financing activities, all of which are presented in the
Operating Partnership's Consolidated Statements of Cash Flows.
 
     During 1996 the Company and/or the Operating Partnership: (i) issued a
total of approximately 14.4 million Common Shares through various offerings and
received total net proceeds of $483 million, (ii) completed the offering of the
Series C Preferred Shares and

received net proceeds of $111.4 million, (iii) issued the 2026 Notes and
received net proceeds of $149 million and (iv) refinanced certain of its tax-
exempt bonds in two separate transactions for a total of $112.2 million of net
proceeds. All of these proceeds were utilized to purchase additional properties
and/or repay the line of credit and mortgage indebtedness on certain Properties.

     With respect to Property acquisitions during 1996, the Operating
Partnership purchased 49 Properties containing 15,665 units for a total
acquisition cost of $778.2 million, which included the assumption of $142.2
million of mortgage indebtedness, the forgiveness of debt of $2.7 million and
the issuance of OP Units having a value of approximately $0.4 million. These
acquisitions were primarily funded from amounts drawn on the Operating
Partnership's line of credit and a portion of the proceeds received in
connection with the transactions mentioned in the previous paragraph.

     During the year ended December 31, 1996, the Operating Partnership also
disposed of five properties which generated net proceeds of approximately $40
million. Proceeds from the dispositions were ultimately applied to purchase
additional Properties.

     As of December 31, 1996, the Operating Partnership had total indebtedness
of approximately $1.3 billion, which included mortgage indebtedness of $755.4
million, of which $274 million represented tax exempt bond indebtedness, and
unsecured debt of $498.8 million (net of a $1.2 million discount). During the
year, the Operating Partnership repaid an aggregate of $57 million mortgage
indebtedness on eight of its Properties. These repayments were funded from the
Operating Partnership's line of credit or from proceeds received from the
various capital transactions mentioned in previous paragraphs.

     During the year ended December 31, 1996, total capital expenditures for the
Operating Partnership approximated $45.9 million. Of this amount, approximately
$10.6 million related to capital improvements and major repairs for certain of
the 1994, 1995 and 1996 Acquired Properties. Capital improvements and major
repairs for all of the Operating Partnership's pre-EQR IPO properties and
Acquired Properties approximated $13.8 million, or $232 per unit. Capital spent
for replacement-type items approximated $16.3 million, or $276 per unit, which
is in line with the Operating Partnership's expected annual recurring per unit
cost. In regard to capital spent for upgrades at certain properties and tenant
improvements with respect to the retail and commercial office space at one
Property, the amount was approximately $2.9 million. Also included in total
capital expenditures was approximately $2.3 million expended for non-real estate
additions such as computer software, computer equipment, furniture and fixtures
and leasehold improvements for the Operating Partnership's management offices
and its corporate headquarters. Such capital expenditures were primarily funded
from working capital reserves and from net cash provided by operating
activities.

Funds From Operations

     Commencing in 1996, the Operating Partnership implemented the new
definition of FFO adopted by the Board of Governors of NAREIT in March 1995.
The new definition primarily eliminates the amortization of deferred financing
costs and depreciation of non-real estate as items added back to net income when
calculating FFO.

     The Operating Partnership generally considers FFO to be one measure of the
performance of real estate companies.  The resolution adopted by the Board of
Governors of NAREIT defines FFO as net income (loss) (computed in accordance
with GAAP), excluding gains (or losses) from debt restructuring and sales of
property, plus depreciation on real estate assets, and after adjustments for
unconsolidated partnerships and joint ventures.  Adjustments for unconsolidated
partnerships and joint ventures are calculated to reflect FFO on the same basis.
The Operating Partnership believes that FFO is helpful to investors as a measure
of the performance of a real estate company because, along with cash flows from
operating activities, financing activities and investing activities, it provides
investors an understanding of the ability of the Operating Partnership to incur
and service debt and to make capital expenditures.  FFO in and of itself does
not represent cash generated from operating activities in accordance with GAAP
and therefore should not be considered an alternative to net income as an
indication of the Operating Partnership's performance or to net cash flows from
operating activities as determined by GAAP as a measure of liquidity and is not
necessarily indicative of cash available to fund cash needs.  The Operating
Partnership's calculation of FFO represents net income, excluding gains on
dispositions of properties, gains on early extinguishment of debt, and write-off
of unamortized costs on refinanced debt, plus depreciation on real estate
assets, amortization of deferred financing costs related to EQR's Predecessor
Business, less an allocation of net income to preference unit holders. The
Operating Partnership's calculation of FFO may differ from the methodology for
calculating FFO utilized by other companies and, accordingly, may not be
comparable to such other companies.

     For the year ended December 31, 1997 FFO increased $110.5 million
representing a 69% increase when compared to the year ended December 31, 1996.
For the year ended December 31, 1996, FFO, based on the Operating Partnership's
calculation of FFO, increased by $39.3 million representing a 32.5% increase
when compared to the year ended December 31, 1995.

                         REPORT OF INDEPENDENT AUDITORS


To the Partners
ERP Operating Limited Partnership

We have audited the accompanying consolidated balance sheets of ERP Operating
Limited Partnership (the "Operating Partnership") as of December 31, 1997 and
1996 and the related consolidated statements of operations, partners' capital
and cash flows for the years then ended. Our audits also included the financial
statement schedule listed in the Index at Item 14(a). These financial statements
and schedule are the responsibility of the Operating Partnership's management.
Our responsibility is to express an opinion on these financial statements and
schedule based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of ERP
Operating Limited Partnership at December 31, 1997 and 1996, and the
consolidated results of its operations and its cash flows for the years then
ended, in conformity with generally accepted accounting principles. Also, in our
opinion, the related financial statement schedule, when considered in relation
to the basic financial statements taken as a whole, presents fairly in all
material respects the information set forth therein.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.   Organization

     ERP Operating Limited Partnership (the "Operating Partnership"), an
Illinois limited partnership, was formed to conduct the multifamily residential
property business of Equity Residential Properties Trust ("EQR"). EQR is a
Maryland real estate investment trust formed on March 31, 1993. As used herein,
the term "Company" means EQR, and its subsidiaries, as the survivor of the
mergers between EQR and each of Wellsford Residential Property Trust
("Wellsford") (the "Wellsford Merger") and Evans Withycombe Residential, Inc.
("EWR") (the "EWR Merger"). The Company conducts substantially all of its
operations through the Operating Partnership. EQR, through the Operating
Partnership, is the successor to the multifamily residential property business
of Equity Properties Management Corp. ("EPMC"), an entity controlled by Mr.
Samuel Zell, Chairman of the Board of Trustees of the Company, and a series of
other entities which owned 69 of the properties (the "Initial Properties").
Forty-six of the Initial Properties (the "Zell Properties") were contributed or
sold by entities substantially controlled by Mr. Zell and primarily owned by Mr.
Zell and trusts for the benefit of Mr. Robert Lurie, a deceased partner of Mr.
Zell. The remaining 23 of the Initial Properties (the "Starwood Properties")
were acquired from entities controlled by Starwood Capital Partners, L.P.
("Starwood") and its affiliates ("Starwood Original Owners"). Prior to the
completion of the Company's initial public offering (the "EQR IPO") of
13,225,000 common shares of beneficial interest, $0.01 par value per share
("Common Shares"), EPMC provided multifamily residential management services
(the "Management Business") to the Zell Properties.

     The Company, through the Operating Partnership, is engaged in the
acquisition, disposition, ownership, management and operation of multifamily
properties.  As of December 31, 1997, the Operating Partnership controlled a
portfolio of 463 multifamily properties (individually a "Property" and
collectively the "Properties") containing 135,200 apartment units.  The
Operating Partnership's interest in six of these Properties at the time of
acquisition thereof consisted solely of ownership of debt collateralized by such
Properties.  The Operating Partnership also has an investment in partnership
interests and subordinated mortgages collateralized by 21 properties and
mortgage loans collateralized by five properties (collectively, the "Additional
Properties").  The Properties and Additional Properties are located throughout
the United States in the following 35 states:  Alabama, Arizona, Arkansas,
California, Colorado, Connecticut, Florida, Georgia, Idaho, Illinois, Indiana,
Iowa, Kansas, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota,
Missouri, Nevada, New Hampshire, New Jersey, New Mexico, North Carolina, Ohio,
Oklahoma, Oregon, South Carolina, Tennessee, Texas, Utah, Virginia, Washington
and Wisconsin.

     In exchange for contributing 33 of the Zell Properties and the Management
Business and the Starwood Properties, the 33 existing entities (the "Zell
Original Owners"), and entities controlled by Starwood and EPMC received a total
of 8,433,238 partnership interests ("OP Units") (including an additional 93,639
OP Units issued in August 1994 and 1,835 OP Units issued in September 1995) in
the Operating Partnership.  The other 13 Zell Properties were acquired from 13
existing partnerships (the "Zell Sellers") for $43.5 million in cash.  The
Management Business, the Zell Original Owners and the Zell Sellers are
collectively "EQR's Predecessor Business."

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (Continued)

 
     The Company has formed a series of partnerships (the "Financing
Partnerships") which beneficially own certain Properties encumbered by mortgage
indebtedness. The Operating Partnership owns a 1% limited partner interest and a
98% general partner interest in each Financing Partnership. The remaining 1%
general partner interest in each Financing Partnership is owned by various
qualified REIT subsidiaries wholly owned by the Company (each a "QRS
Corporation"). Rental income from the Properties that are beneficially owned by
a Financing Partnership is used first to service the applicable mortgage debt
and pay other operating expenses and any excess is then distributed 1% to the
applicable QRS Corporation, as the general partner of such Financing
Partnership, and 99% to the Operating Partnership, as the sole 1% limited
partner and as the 98% general partner. The Company has also formed a series of
limited liability companies (the "LLCs") which own certain Properties and one
such LLC which has an investment in partnership interests and subordinated
mortgages collateralized by 21 of the Additional Properties. The Operating
Partnership is a 99% managing member of each LLC and a QRS Corporation is a 1%
member of each LLC. In addition, the Company also owns a 1% general partner
interest and a 81.1% limited partner interest in Evans Withycombe Residential,
L. P. (the "EWR Operating Partnership") and the Operating Partnership owns a
16.1% limited partner interest and a 1% managing general partner interest in the
EWR Operating Partnership.

     As of December 31, 1997, 451 Properties were managed by either Equity
Residential Properties Management Limited Partnership, the successor to the
Management Business contributed by EPMC contemporaneously with the EQR IPO and
Equity Residential Properties Management Limited Partnership II (collectively,
the "Management Partnerships"). The Management Partnerships collect a property
management fee consistent with a reasonable arms-length charge for the
performance of such services. The sole general partners of the Management
Partnerships with a 1% interest is the Operating Partnership. The sole limited
partners of the Management Partnerships are Equity Residential Properties
Management Corp. ("Management Corp.") and Equity Residential Properties
Management Corp. II ("Management Corp. II"), respectively, and each has a 99%
interest in the respective partnership.

2.   Basis of Presentation

     The Wellsford Merger and the EWR Merger (collectively, the "Mergers") were
treated as purchases in accordance with Accounting Principles Board Opinion No.
16.  The fair value of the consideration given by the Company in the Mergers was
used as the valuation basis for each of the combinations.  The assets acquired
and the liabilities assumed of Wellsford were recorded at their relative fair
values as of May 30, 1997 (the "Wellsford Closing Date").  The assets acquired
and the liabilities assumed of EWR were recorded at their relative fair values
as of December 23, 1997 (the "EWR Closing Date").  The accompanying consolidated
statements of operations and cash flows include the results of both Wellsford
and EWR from their respective closing dates.

     Due to the Operating Partnership's ability to control, either through
ownership or by contract, the Management Partnerships, the Financing

financial reporting purposes. In regard to Management Corp., Management Corp. II
and Evans Withycombe Management, Inc., the Operating Partnership does not have
legal control; however, these entities are consolidated for financial reporting
purposes, the effects of which are immaterial. Certain reclassifications have
been made to the prior year's financial statements in order to conform to the
current year presentation.

     Minority interests represented by the Company's indirect 1% interest in
various Financing Partnerships and LLCs are immaterial and have not been
accounted for in the Consolidated Financial Statements.  In addition, certain
amounts due from the Company for its 1% interest in the Financing Partnerships
has not been reflected in the Consolidated Balance Sheets since such amounts are
immaterial to the Consolidated Balance Sheets.

3.   Business Combinations

     In connection with the Wellsford Merger each outstanding common share of
beneficial interest of Wellsford was converted into .625 of a Common Share of
the Company.  In addition, Wellsford's Series A Cumulative Convertible Preferred
Shares of Beneficial Interest were redesignated as the Company's 3,999,800
Series E Cumulative Convertible Preferred Shares of Beneficial Interest, $0.01
par value per share (the "Series E Preferred Shares") and Wellsford's Series B
Cumulative Redeemable Preferred Shares of Beneficial Interest were redesignated
as the Company's 2,300,000 9.65% Series F Cumulative Redeemable Preferred Shares
of Beneficial Interest, $0.01 par value per share (the "Series F Preferred
Shares").

     On the Wellsford Closing Date, 72 Properties containing 19,004 units and
other related assets were acquired for a total purchase price of approximately
$1 billion.  The purchase price consisted of 10.8 million Common Shares issued
by the Company with a market value of $443.7 million, the liquidation value of
$157.5 million for the Series E Preferred Shares and the Series F Preferred
Shares, the assumption of mortgage indebtedness and unsecured notes in the
amount of $345 million, the assumption of other liabilities of approximately
$33.5 million and other merger related costs of approximately $23.4 million. 
Upon contribution of the net assets by the Company to the Operating Partnership,
the Operating Partnership issued 10.8 million OP Units to the Company.

     On the EWR Closing Date, 53 Properties containing 15,331 units and three
Properties under construction or expansion expected to contain 953 units and
other related assets were acquired for a total purchase price of approximately
$1.2 billion. In connection with the EWR Merger, as of the EWR Closing Date,
each outstanding common share of beneficial interest of EWR was converted into
 .50 of a Common Share of the Company. The purchase price consisted of the
Operating Partnership's contribution of the EWR Operating Partnership OP Units
to the Operating Partnership at a market value of approximately $501.6 million,
issuance of approximately 2.2 million Operating Partnership OP Units, in
exchange for approximately 4.4 million EWR Operating Partnership OP Units at a
market value of approximately $107.3 million, the assumption of mortgage
indebtedness and unsecured notes in the amount of $498 million, the assumption
of other liabilities of approximately $28.2 million and other EWR Merger related
costs of approximately $16.7 million.

4.   Partner's Capital

     The limited partners of the Operating Partnership as of December 31, 1997
include various individuals and entities that contributed their properties to
the Operating Partnership in exchange for a partnership interest (the "Limited
Partners") and are represented by 9,592,590 OP Units which are exchangeable,
subject to certain restrictions, on a one-for-one basis into the Company's
Common Shares. As of December 31, 1997, the General Partner had an approximate
90.28% interest and the Limited Partners had an approximate 9.72% interest.

     In regards to the General Partner, net proceeds from the various equity
offerings of the Company have been contributed by the Company to the Operating
Partnership in return for an increased ownership percentage. Due to the Limited
Partner's ability to convert their interest into an ownership interest in the
General Partner, the net offering proceeds are allocated between the Company (as
general partner) and the Limited Partners (to the extent represented by OP
Units) to account for the change in their respective percentage ownership of the
equity of the Operating Partnership.

5.   Summary of Significant Accounting Policies

     (a)  Real estate assets and depreciation

     Real estate is recorded at cost less accumulated depreciation less an
adjustment, if any, for impairment. Real estate intended to be held and operated
by the Operating Partnership over their remaining useful life are reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of the particular real estate may not be recoverable. If these
events or changes in circumstances are present, the Operating Partnership
estimates the sum of the

                                      F-15
<PAGE>

                       ERP OPERATING LIMITED PARTNERSHIP

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (Continued)
 
expected future cash flows (undiscounted) to result from the operations and
eventual disposition of the particular real estate, and if less than the
carrying amount of the real estate, the Operating Partnership will recognize an
impairment loss. Upon recognition of any impairment loss the Operating
Partnership measures that loss based on the amount by which the carrying amount
of the real estate exceeds the estimated fair value of the real estate.

     For rental properties to be disposed of, an impairment loss is recognized
when the fair value of the real estate, less the estimated cost to sell, is less
than the carrying amount of the real estate measured at the time the Operating
Partnership has a commitment to sell the property and/or is actively marketing
the property for sale.  Real estate to be disposed of is reported at the lower
of its carrying amount or its estimated fair value, less its cost to sell.
Depreciation is not recorded during the period in which assets are held for
disposal.

     Depreciation is computed on a straight-line basis over the estimated useful
lives of the assets.  The Operating Partnership uses a 30-year estimated life
for buildings, a 10-year estimated life for land improvements and up to a seven-
year estimated life for furniture, fixtures and equipment.  Expenditures for
ordinary maintenance and repairs are expensed to operations as incurred and
significant renovations and improvements that improve and/or extend the useful
life of the asset are capitalized over their estimated useful life.  Initial
direct leasing costs are expensed as incurred and such expense approximates the
deferral and amortization of initial direct leasing costs over the lease terms.
Property sales or dispositions are recorded when title transfers and sufficient
consideration has been received by the Operating Partnership.  Upon disposition,
the related costs and accumulated deprecation are removed from the respective
accounts.  Any gain or loss on sale or disposition is recognized in accordance
with generally accepted accounting principles.

     The Operating Partnership classifies developments and lease-up properties
as construction-in-progress until construction on the apartment community has
been completed and the apartment community has reached stabilized occupancy. The
Operating Partnership generally considers a property stabilized when it first
reaches 93% physical occupancy. The Operating Partnership also classifies land
relating to construction-in-progress as land on its balance sheet. Land
associated with construction-in-progress was $8.3 million as of December 31,
1997.

     (b)  Cash and Cash Equivalents

     The Operating Partnership considers all demand deposits, money market
accounts and investments in certificates of deposit and repurchase agreements
purchased with a maturity of three months or less, at the date of purchase, to
be cash equivalents.  The Operating Partnership maintains its cash and cash
equivalents at financial institutions.  The combined account balances at each
institution periodically exceed the Federal Depository Insurance Corporation
("FDIC") insurance coverage, and, as a result, there is a concentration of
credit risk related to amounts on deposit in excess of FDIC insurance coverage.
The Operating Partnership believes that the risk is not significant, as the
Operating Partnership does not anticipate their non-performance.

                                  (Continued)
 
     (c)  Deferred Financing Costs

     Deferred financing costs include fees and costs incurred to obtain the
Operating Partnership's lines of credit, long-term financing and costs for
certain interest rate protection agreements.  These costs are amortized over the
terms of the related debt.  Unamortized financing costs are written-off when
debt is retired before the maturity date.  As of December 31, 1997 and 1996, the
accumulated amortization of such deferred financing costs was $4.2 million and
$3.8 million, respectively.

     (d)  Interest Rate Protection Agreements

     The Operating Partnership from time to time enters into interest rate
protection agreements to effectively convert floating rate debt to a fixed rate
basis, as well as to hedge anticipated financing transactions. Net amounts paid
or received under these agreements are recognized as an adjustment to interest
expense when such amounts are incurred or earned. Settlement amounts paid or
received in connection with terminated interest rate protection agreements are
deferred and amortized over the remaining term of the related financing
transaction on the straight-line method.  The Operating Partnership believes it
has limited exposure to the extent of non-performance by the counterparties of
each protection agreement since each counterparty is a major U.S. financial
institution, and the Operating Partnership does not anticipate their non-
performance.

     (e)  Fair Value of Financial Instruments

     The fair values of the Operating Partnership's financial instruments,
including cash and cash equivalents, and mortgage notes payable, other notes
payable, lines of credit and other financial instruments, approximate their
carrying or contract values.  With respect to the Operating Partnership's
investment in mortgage notes, the fair value as of December 31, 1997 was
estimated to be approximately $184.8 million compared to the Operating
Partnership's carrying value of $176.1 million.  The estimated fair value of the
Operating Partnership's investment in mortgage notes represents the estimated
net present value based on the expected future property level cash flows and an
estimated current market discount rate.

     (f)  Revenue Recognition

     Rental income attributable to leases is recorded when due from tenants and
is recognized monthly as it is earned, which is not materially different than on
a straight-line basis. Interest income is recorded on an accrual basis.

     (g)  Lease Agreements

     A substantial portion of the leases entered into between the tenant and a
multifamily property for the rental of an apartment unit is month-to-month or
year-to-year, renewable upon consent of both parties.

                                  (Continued)
 
     (h)  Income Taxes

     The Operating Partnership is not liable for Federal income taxes as the
partners recognize their proportionate share of the Operating Partnership income
or loss in their tax returns, therefore, no provision for Federal income taxes
is made in the financial statements of the Operating Partnership. However, the
Operating Partnership is subject to certain state and local income, excise and
franchise taxes.  The aggregate cost of land and depreciable property for
Federal income tax purposes as of December 31, 1997 was approximately $6.2
billion.

     (i)  Income per OP Unit

     In 1997, the Financial Accounting Standards Board issued Statement No. 128,
Earnings per Share ("Statement 128"). Statement 128 replaced the calculation of
primary and fully diluted earnings per share with basic and diluted earnings per
share. Unlike primary earnings per share, basic earnings per share excludes any
dilutive effects of options, warrants and convertible securities. Diluted
earnings per share is very similar to the previously reported fully diluted
earnings per share. All net income per weighted average OP Unit and net income
per weighted average OP Unit--assuming dilution amounts for all periods have
been presented and, where appropriate, restated to conform to the Statement 128
requirements.

     (j)  Cash Distributions and Allocation of Income (Loss)

     Distributions, profits and losses are generally allocated to the General
Partner and the Limited Partners in proportion to their respective percentage
interests.

     (k)  Use of Estimates

     In preparation of the Operating Partnership's financial statements in
conformity with generally accepted accounting principles, management makes
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements as well as the reported amounts of revenues and
expenses during the reporting period.  Actual results could differ from these
estimates.

     the computation of diluted earnings per OP Unit because it would be anti-
     dilutive.

     opportunity to acquire Common Shares through the grant of share options
     ("Options") to officers, directors, key employees and consultants of the
     Company for 4.1 million, 2.3 million and 1.4 million Common Shares at a

     Share as of December 31, 1997, 1996 and 1995, respectively. As of December
     31, 1997, 1996 and 1995, 1.3 million, .9 million, and .7 million Common
     Shares were exercisable, respectively. Any Common Shares issued pursuant to
     the Company's share option plan will result in the Operating Partnership
     issuing OP Units to the Company on a one-for-one basis. Accordingly, the

10. Investment in Mortgage Notes and Partnership Interests

     In 1995, the Operating Partnership made an $89 million investment in
partnership interests and subordinated mortgages collateralized by 21 of the
Additional Properties. These 21 Additional Properties consist of 3,896 units,
located in California, Colorado, New Mexico and Oklahoma. This included an $87.1
million investment in second and third mortgages (net of an original discount of
approximately $12.7 million to their face value), $1.6 million represents a one
time payment for an interest rate protection agreement and $0.3 million
represents an investment for primarily a 49.5% limited partnership interest in
the title-holding entities. As the Operating Partnership does not control the
general partners of the title-holding entities and substantially all of the
Operating Partnership's investment is in second and third mortgages (which are
subordinate to first mortgages owned by third party unaffiliated entities), the
$87.1 million investment is accounted for as an investment in mortgage notes.
The $1.6 million payment made for the interest rate protection agreement is
included in deferred financing costs and is being amortized over the term of the
related debt. The investment in limited partnership interests is accounted for
under the equity method and is included in other assets on the balance sheet.

     As of December 31, 1997 the second mortgage notes had a combined principal
balance of approximately $25.5 million, accrue interest at a rate of 9.45% per
annum, receive principal amortization from excess cash flow and have a stated
maturity date of December 31, 2019. The third mortgage notes had a combined
principal balance of approximately $71.1 million, accrue interest at a rate of
6.15% per annum, plus up to an additional 3% per annum to the extent of
available cash flow. Contingent interest on the third mortgage notes is
recognized to the extent it is determined to be received. The third mortgage
notes have a stated maturity of December 31, 2024. Receipt of principal and
interest on the second and third mortgage notes is subordinated to the receipt
of all interest on the first mortgage notes. With respect to the discount on
these notes, the unamortized balance at December 31, 1997 was $9 million. During
1997 and 1996, the Operating Partnership amortized $3.1 million and $0.6
million, respectively, which is included in interest income - investment in
mortgage notes in the consolidated statement of operations. This discount is
being amortized utilizing the effective yield method.

     On April 28, 1997, the Operating Partnership made an $88 million investment
in six mortgage loans collateralized by five multifamily properties. These five
multifamily properties are included in the Additional Properties. As of December
31, 1997, these six mortgage loans had a combined principal balance of
approximately $88 million and accrue interest at a rate of 8.25%. These six
mortgage loans are scheduled to mature on January 1, 2006.

11. Mortgage Notes Payable

     As of December 31, 1997, the Operating Partnership had outstanding mortgage
indebtedness of approximately of $1.6 billion encumbering 152 of the Properties.
The carrying value of such Properties (net of accumulated depreciation of $145.1
million) was approximately $2.6 billion. The mortgage notes payable are
generally due in monthly installments of interest only. In connection

with the Properties acquired during the year ended December 31, 1997, including
the effects of the Mergers, the Operating Partnership assumed the outstanding
mortgage balances on 90 Properties in the aggregate amount of $931 million,
which includes a premium of approximately $3.9 million recorded in connection
with the EWR Merger.

     Concurrent with the refinancing of certain tax-exempt bonds and as a
requirement of the credit provider of the bonds, the Financing Partnership,
which owns certain of the Properties, entered into interest rate protection
agreements, which were assigned to the credit provider as additional security.
The Financing Partnership pays interest based on a fixed interest rate and the
counterparty of the agreement pays interest to the Operating Partnership at a
floating rate that is calculated based on the Public Securities Association
Index for municipal bonds ("PSA Municipal Index"). As of December 31, 1997 and
1996, the aggregate notional amounts of these agreements were approximately
$174.3 million and $166.8 million, respectively. The fixed interest rates for
these agreements were 4.81%, 4.528% and 4.90%. The termination dates are October
1, 2003, January 1, 2004 and April 1, 2004. The Operating Partnership
simultaneously entered into substantially identical reverse interest rate
protection agreements. Under these agreements the Operating Partnership pays
interest monthly at a floating rate based on the PSA Municipal Index and the
counterparty pays interest to the Operating Partnership based on a fixed
interest rate. As of December 31, 1997 and 1996, the aggregate notional amount
of these agreements was approximately $174.3 million and $166.8 million,
respectively. The fixed interest rates received by the Operating Partnership in
exchange for paying interest based on the PSA Municipal Index for these
agreements were 4.74%, 4.458% and 4.83%. The termination dates are October 1,
2003, January 1, 2004 and April 1, 2004. Collectively, these agreements
effectively cost the Operating Partnership 0.07% per annum on the current
outstanding aggregate notional amount. The Operating Partnership believes that
it has limited exposure to the extent of non-performance by the counterparties
of the agreements since each counterparty is a major U.S. financial institution,
and the Operating Partnership does not anticipate their non-performance.
Furthermore, any non-performance by the counterparty is offset by non-
performance by the Operating Partnership.

     The Operating Partnership also has an interest rate cap agreement for a
notional amount of $228,000,000, for which it will receive payments if the PSA
index exceeds 5.75%, that terminates on December 1, 1999. Any payments by the
counterparty under this agreement have been collaterally assigned to the
provider of certain sureties related to the tax exempt bonds secured by certain
of it's Properties. The Operating Partnership has no payment obligations to the
counterparty with respect to this agreement.

     As of December 31, 1997, scheduled maturities for the Operating 
Partnership's outstanding mortgage indebtedness are at various dates through
October 1, 2030. During the year ended December 31, 1997, effective interest
cost on certain of these mortgage notes was 7.5%. During the year ended December
31, 1997, the Operating Partnership repaid the outstanding mortgage balances on
29 Properties in the aggregate amount of $113.4 million. Subsequent to December
31, 1997, the Operating Partnership repaid the outstanding mortgage balance on
one Property in the amount of approximately $18.2 million. In February 1996, the
Operating Partnership entered into an interest rate protection agreement, which
hedged the interest rate risk of $50 million of mortgage loans, scheduled to
mature in September 1997 by locking the five year Treasury Rate, commencing
October 1, 1997 through October 1, 2002. This agreement was cancelled in July
1997, at no cost to the Operating Partnership, in conjunction with the Operating
Partnership entering into another interest rate protection agreement to
effectively fix the cost of the Operating Partnership's unsecured notes issued
in November 1997.

     As of December 31, 1996, the Operating Partnership had outstanding mortgage
indebtedness of approximately $755.4 million encumbering 88 of the Properties.
The carrying value of such Properties (net of accumulated depreciation of $141.2
million) was $1.1 billion. The mortgage notes payable are generally due in
monthly installments of interest only. In connection with the Properties
acquired during the year ended December 31, 1996, the Operating Partnership
assumed the outstanding mortgage balances on 14 Properties in the aggregate
amount of $142.2 million. In addition, during 1996, in two separate
transactions, certain indebtedness evidenced by tax-exempt bonds encumbering
certain Properties was refinanced resulting in an increase in mortgage
indebtedness affecting these Properties of approximately $112 million. In
connection with one of these transactions, the Operating Partnership also
recorded an extraordinary loss in the amount of approximately $3.5 million,
which represented the write-off of unamortized deferred financing costs from the
early retirement of debt.

     During the year ended December 31, 1996, the effective interest cost on
these mortgage notes was 7.87%. During the year ended December 31, 1996, the
Operating Partnership repaid the outstanding mortgage balances on eight
Properties in the aggregate amount of $57 million.

     During 1996 the Operating Partnership terminated two interest rate
protection agreements that were initially entered into in connection with two
mortgage loans with notional amounts totaling $64.2 million. These two
agreements effectively converted these two mortgage loans to fixed rate
instruments based on the London Interbank Offered Rate ("LIBOR"). Upon the
termination of these agreements the Operating Partnership received settlement
payments of approximately $230,000.

     Aggregate payments of principal on mortgage notes payable for each of the
next five years and thereafter are as follows:

unsecured line of credit. In September 1997, this agreement was amended to
increase the potential borrowings to $500 million. This line of credit matures
in November 1999 and borrowings generally will bear interest at a per annum rate
of one, two, three or six month LIBOR, plus a certain rate dependent upon the
Operating Partnership's credit rating, which rate is currently 0.45%, and is
subject to an annual facility fee of $750,000. As of December 31, 1997, $235
million was outstanding on this line of credit, bearing interest at a weighted
average rate of 6.46%.

13.  Notes

     On May 16, 1994, the Operating Partnership issued $125 million of unsecured
senior notes (the "1999 Notes") in a private placement (the "Debt Offering") to
qualified institutional buyers. The 1999 Notes were issued at a discount, which
is being amortized over the life of the 1999 Notes on a straight-line basis.  As
of December 31, 1997 the unamortized discount balance was approximately $0.2
million. The 1999 Notes are due May 15, 1999 and bear interest at a rate of
8.5%, which is payable semiannually in arrears on May 15 and November 15. In
February 1996, the Operating Partnership entered into an interest rate
protection agreement that hedged the interest rate risk of the 1999 Notes by
locking the effective four year Treasury Rate commencing May 15, 1999. There was
no current cost to the Operating Partnership for entering into this agreement.

     In December 1994, the Operating Partnership registered $500 million in debt
securities pursuant to a debt shelf registration statement (the "Debt Shelf
Registration") of which $100 million of unsecured floating rate notes (the
"Floating Rate Notes") were issued by the Operating Partnership on December 22,
1994 (the "Public Debt Offering").  The Floating Rate Notes were repaid at
maturity on December 22, 1997.

     In April 1995, the Operating Partnership issued $125 million of unsecured
fixed rate notes (the "2002 Notes") in connection with the Debt Shelf
Registration in a public debt offering (the "Second Public Debt Offering").  The
2002 Notes were issued at a discount, which is being amortized over the life of
the 2002 Notes on a straight-line basis.  As of December 31, 1997 the
unamortized discount balance was approximately $0.6 million.  The 2002 Notes are
due on April 15, 2002 and bear interest at 7.95%, which is payable semi-annually
on each October 15 and April 15.  The Operating Partnership received net
proceeds of $123.1 million in connection with the Second Public Debt Offering.
Prior to the issuance of the 2002 Notes, the Operating Partnership entered into
an interest rate protection agreement to effectively fix the interest rate cost
of such issuance. The Operating Partnership made a one-time settlement payment
of this protection transaction, which was approximately $0.8 million, which
amount is being amortized over the term of the 2002 Notes. As of December 31,
1997 the unamortized balance of this cost was approximately $0.5 million.

     In August 1996, the Operating Partnership issued $150 million of unsecured
fixed rate notes (the "2026 Notes") in connection with the Debt Shelf
Registration in a public debt offering (the "Third Public Debt Offering").  The
2026 Notes are due on August 15, 2026 and bear interest at 7.57%, which is
payable semi-annually in arrears on February 15 and August 15, commencing
February 15, 1997.  The 2026 Notes are redeemable at any time after August 15,
2006 by the Operating Partnership pursuant to the terms thereof.  The Operating
Partnership received net proceeds of approximately $149 million in connection
with this issuance.  Prior to the issuance of the 2026 Notes, the Operating
Partnership entered into an interest rate protection agreement to effectively
fix the interest rate cost of this issuance to 7.5%.  The Operating Partnership
received a one-time settlement payment from this transaction, which was
approximately $0.6 million, which amount is being amortized over the term of the

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (Continued)
 
     On September 18, 1996, the Operating Partnership filed with the SEC a Form
S-3 Registration Statement to register $500 million of debt securities (the
"1996 Debt Shelf Registration").  The SEC declared this Registration effective
on September 23, 1996.

     In October 1997, the Operating Partnership issued $150 million of unsecured
fixed rate notes (the "2017 Notes") in connection with the 1996 Debt Shelf
Registration in a public debt offering (the "October 1997 Public Debt
Offering"). The 2017 Notes were issued at a discount, which is being amortized
over the life of the 2017 Notes on a straight-line basis. As of December 31,
1997 the unamortized discount balance was approximately $1.2 million. The 2017
Notes are due on October 15, 2017 and bear interest at 7.125%, which is payable
semiannually in arrears on April 15 and October 15, commencing April 15, 1998.
The 2017 Notes are redeemable at any time by the Operating Partnership pursuant
to the terms thereof. The Operating Partnership received net proceeds of
approximately $147.4 million in connection with this issuance.

     In November 1997, the Operating Partnership issued $200 million of
unsecured fixed rate notes in connection with the 1996 Debt Shelf Registration
in a public debt offering (the "November 1997 Public Debt Offering"). Of the
$200 million issued, $150 million of these notes are due November 15, 2001 (the
"2001 Notes") and bear interest at a rate of 6.55%, which is payable
semiannually in arrears on May 15 and November 15, commencing on May 15, 1998.

Notes") and bear interest at a rate of 6.65%, which is payable semiannually in
arrears on May 15 and November 15, commencing on May 15, 1998. The 2001 Notes
were issued at a discount, which is being amortized over the life of the 2001
Notes on a straight-line basis. As of December 31, 1997 the unamortized discount
balance was approximately $0.3 million. The Operating Partnership received net
proceeds of approximately $148.9 million in connection with the 2001 Notes. The
2003 Notes were issued at a discount, which is being amortized over the life of
the 2003 Notes on a straight-line basis. As of December 31, 1997 the unamortized
discount balance was approximately $0.1 million. The Operating Partnership
received net proceeds of approximately $49.6 million in connection with the 2003
Notes. Prior to the issuance of the 2001 and 2003 Notes, the Operating
Partnership entered into two interest rate protection agreements to effectively
fix the interest rate costs of such issuances. The Operating Partnership made a
one time settlement payment for each protection transaction, which was
approximately $5 million and $1.7 million, respectively, which are being
amortized over the term of the Notes on a straight-line basis. As of December
31, 1997 the unamortized balance of these costs were approximately $4.9 million
and $1.6 million, respectively.

     Included in the note balance are four unsecured note issuances assumed in
connection with the Wellsford Merger.  These are discussed in the following
three paragraphs.
 
     In January 1995, $100 million of senior unsecured notes due February 1,
2002 (the "2002-A Notes") were issued.  The 2002-A Notes bear interest at a rate
of 9.375%, which is payable semiannually in arrears on August 1 and February 1.
In connection with the assumption of the 2002-A Notes, the Operating Partnership
recorded a premium in the amount of $5.6 million, which is being amortized over
the remaining life of the notes on a straight-line basis. As of December 31,
1997, the unamortized premium balance relating to the 2002-A Notes was
approximately $4.9 million.

     In August 1995,  $125 million of senior unsecured notes were issued.  Of
the $125 million issued, $55 million of these notes are due August 15, 2000 (the
"2000 Notes") and bear interest at a rate of 7.25%, which is payable
semiannually in arrears on February 15 and August 15.  The remaining $70 million
of these notes are due August 15, 2005 (the "2005 Notes") and bear interest at a
rate of 7.75%, which is payable semiannually in arrears on February 1 and August
1.

     In November 1996, $25 million of medium term unsecured floating rate notes
due November 24, 1999 (the "1999-A Notes") were issued.  The 1999-A Notes bear
interest at 90 day LIBOR plus 0.32%, which is payable quarterly in arrears on
the 25th day of each February, May, August and November.
 
     Also included in the note balance are two unsecured note issuances assumed
in connection with the EWR Merger.  These are discussed in the following two
paragraphs.

     In April 1997, $75 million of senior unsecured notes due April 15, 2004
(the "2004 Notes") were issued.  The 2004 Notes bear interest at a rate of 7.5%,
which is payable semiannually in arrears on October 15 and April 15. In
connection with the assumption of the 2004 Notes, the Operating Partnership
recorded a premium in the amount of $1.7 million, which is being amortized over
the remaining life of the notes on a straight-line basis. As of December 31,
1997, the unamortized premium balance relating to the 2004 Notes was
approximately $1.7 million.
 
     In April 1997, $50 million of senior unsecured notes due April 15, 2007
(the "2007 Notes") were issued.  The 2007 Notes bear interest at a rate of
7.625%, which is payable semiannually in arrears on October 15 and April 15. In
connection with the assumption of the 2007 Notes, the Operating Partnership
recorded a premium in the amount of $1.6 million, which is being amortized over
the remaining life of the notes on a straight-line basis. As of December 31,
1997, the unamortized premium balance relating to the 2007 Notes was
approximately $1.6 million.

     In regard to all of the interest rate protection agreements mentioned in
the previous paragraphs, the Operating Partnership believes that it has limited
exposure to the extent of non-performance by the counterparties of each
agreement since each counterparty is a major U.S. financial institution and the
Operating Partnership does not anticipate their non-performance.

14.  Redeemable Preference Interests

     In connection with the acquisition of seven of the Properties which closed
in December 1994, the Company, through the Operating Partnership, issued 41,213
preferred interests ("Preference Units") to certain sellers of these Properties.
The Preference Units had a stated value of $1,000 and entitled the holders
thereof to preferential distributions from the Operating Partnership (other than
liquidating distributions) before distributions to the holders of the OP Units
and the Company (provided the Company shall be entitled to receive distributions
necessary to maintain its REIT status under U.S. tax laws). The Operating
Partnership also made loans to certain of these sellers in the aggregate amount
of $15.2 million, which loans are fully collateralized by 465,545 OP Units.

194,000 Common Shares at prices which range from $26 to $31.625 per Common
Share.  These purchases were financed by loans made by the Company in the
aggregate amount of approximately $5.4 million.  The employee notes accrue
interest, payable in arrears, at rates that range from 6.15% per annum to 7.93%
per annum.  Scheduled maturities are at various dates through March 2005.  The
employee notes are recourse to Mr. Crocker and the four other officers and are
collateralized by pledges of the 194,000 Common Shares purchased.  Subsequent to
December 31, 1997, one of the four other officers repaid his note in full.

     In addition, as of December 31, 1997, the outstanding principal balance on
additional notes issued to Mr. Crocker and one other officer was approximately
$0.7 million.  These notes accrue interest, payable in arrears, at one month
LIBOR plus 2% per annum.  Scheduled maturities are at various dates through
March 2003.  The notes are recourse to Mr. Crocker and the other officer and are
collateralized by pledges of options, share awards and Common Shares purchased.

     Mr. Crocker has a deferred compensation agreement (the "Deferred
Compensation Agreement") which Deferred Compensation Agreement will provide Mr.
Crocker with a salary benefit after his termination of employment with the
Operating Partnership.  If Mr. Crocker's employment is terminated by the 
Company, without cause or voluntarily by Mr. Crocker after age 65, he would be
entitled to annual deferred compensation for a 10-year period commencing on the
termination date in an amount equal to his average annual base compensation
(before bonus) for the prior five calendar years, multiplied by a percentage
equal to 10% per year since December 31, 1995. In the event Mr. Crocker's
employment is terminated as a result of his death, permanent disability or
incapacity, he would be entitled to a similar amount except the annual
percentage would be 15%, not 10%. Should Mr. Crocker be terminated for cause or
should he choose to leave voluntarily prior to age 65, without good reason, he
would not be entitled to any deferred compensation. The Operating Partnership 
recognized approximately $0.5 million of compensation expense for both 1997 and
1996 related to this Deferred Compensation Agreement.

     In addition, Gerald Spector, Executive Vice President and Chief Operating
Officer of the Company, entered into a Deferred Compensation Agreement in 1997,
which agreement provides Mr. Spector with a salary benefit after his termination
of employment with the Company.  If Mr. Spector's employment is terminated,
by the Company, without cause or voluntarily by Mr. Spector after age 65, he
would be entitled to annual deferred

compensation for a 15-year period commencing on the termination date in an
amount equal to 75% of his average annual base compensation (before bonus) for
the prior five calendar years, multiplied by a percentage equal to 6.67% per
each year since December 31, 1996. In the event Mr. Spector's employment is
terminated as a result of his death, permanent disability or incapacity, he
would be entitled to a similar amount except that the annual percentage would be
10%, not 6.67%. Should Mr. Spector be terminated for cause or should he choose
to leave voluntarily prior to age 65, without good reason, he would not be
entitled to any deferred compensation. The Operating Partnership recognized
approximately $0.2 million of compensation expense in 1997 related to this
Deferred Compensation Agreement.

     The Board of Trustees also approved a share distributions agreement (the
"Share Distributions Agreement") for Mr. Crocker. On January 18, 1996, Mr.
Crocker was issued options to purchase 100,000 Common Shares at the then current
market price of the Common Shares, which vest over a 3-year period and are
effective for 10 years. Pursuant to the terms of the Share Distributions
Agreement, upon the exercise of any of these options, Mr. Crocker would be
entitled to an amount equal to the amount of Common Share distributions that
would have been paid on said shares being exercised had he owned said shares for
the period from January 18, 1996 until the date of the exercise of the options
in question. Mr. Crocker's death or termination of employment would not affect
this agreement with the Company.

     In May 1997, Jeffrey Lynford and Edward Lowenthal (trustees of the Company)
each executed a consulting agreement with the Company.  Each consulting
agreement has a term of five years from May 30, 1997, the closing date of the
Wellsford Merger.  Pursuant to the consulting agreements, each of Messrs.
Lynford and Lowenthal will serve as a senior management consultant to the
Company and will receive compensation at the rate of $200,000 per year plus
reimbursement for reasonable out-of-pocket expenses.

     In connection with the EWR Merger, in December 1997, Stephen Evans executed
a consulting agreement with an affiliate of the Company.  The consulting
agreement has a term of two years and expires on December 31, 1999.  Pursuant to
the consulting agreement, Mr. Evans will serve as a senior management consultant
to the Company and will receive compensation at the rate of $225,000 per year.
Mr. Evans also received an option to purchase 115,500 Common Shares that will
vest in three equal annual installments and will have an exercise price equal to
$50.125 per Common Share. Mr. Evans will also be eligible to participate in all
of the Company's employee benefit plans in which persons in comparable positions
participate, treating Mr. Evans as an employee.

     Also in connection with the EWR Merger, in December 1997, Richard Berry
executed an employment agreement with an affiliate of the Company which expires
on December 31, 2000 and provides for cash compensation of $250,000 per annum.
Pursuant to the agreement, Mr. Berry exchanged all unvested restricted shares of
Evans common shares at the time of the EWR Merger into 18,747 restricted Common
Shares of the Company, which will vest on December 31, 2000. Mr. Berry also
received an option to purchase 77,500 Common Shares that will vest in three
equal annual installments and will have an exercise price equal to $50.125 per
Common Share. The

agreement also provided that Mr. Berry will be eligible to participate in all of
the Company's employee benefit plans which persons in comparable positions
participate.

     In December 1997, Mr. Berry also entered into a Deferred Compensation
Agreement with the Company, which will pay benefits only in the event Mr.
Berry's employment with the Company is terminated prior to January 1, 2000.  In
such a case, the amount payable under Mr. Berry's agreement will equal the value
of any restricted Common Shares received in exchange for EWR common shares which
are forfeited upon his termination of employment.  The payment will be made in
two semi-annual installments over the one-year period following termination of
employment, and interest of 9% per annum will accrue on the balance over the
one-year payment period.

     The Company has established a defined contribution plan (the "401(k) Plan")
that provides retirement benefits for employees that meet minimum employment
criteria.  The Company contributes 100% of the first 4% of eligible compensation
that a participant contributes to the 401(k) Plan. Participants are vested in

net prices that ranged from $35.63 per share to $42.08 per share and raised

27.  Distribution Reinvestment and Share Purchase Plan

     On November 3, 1997, the Company filed with the SEC a Form S-3 Registration
Statement to register 7,000,000 Common Shares pursuant to a Distribution
Reinvestment and Share Purchase Plan.  The registration statement was declared
effective on November 25, 1997.

     The Distribution Reinvestment and Share Purchase Plan (the "DRIP Plan") of
the Company provides holders of record and beneficial owners of Common Shares,
Preferred Shares, and limited partnership interests in the Operating Partnership
with a simple and convenient method of investing cash distributions in
additional Common Shares. Common Shares may also be purchased on a monthly basis
with optional cash payments made by participants in the Plan and interested new
investors, not currently shareholders of the Company, at the market price of the
Common Shares less a discount ranging between 0% and 5% (as determined in
accordance with the DRIP Plan). The proceeds from the sale were contributed to
the Operating Partnership in exchange for OP Units.


28.  Commitments and Contingencies

     The Operating Partnership, as an owner of real estate, is subject to
various environmental laws of Federal and local governments.  Compliance by the
Operating Partnership with existing laws has not had a material adverse effect
on the Operating Partnership's financial condition and results of operations.
However, the Operating Partnership cannot predict the impact of new or changed
laws or regulations on its current Properties or on properties that it may
acquire in the future.

     The Operating Partnership does not believe there is any other litigation,
except as mentioned in the previous paragraph, threatened against the Operating
Partnership other than routine litigation arising out of the ordinary course of
business, some of which is expected to be covered by liability insurance, none
of which is expected to have a material adverse effect on the consolidated
financial statements of the Operating Partnership.

     In connection with the Joint Venture Agreement, as discussed in Note 7, the
Operating Partnership is obligated to fund an additional $20 million in
connection with the third party construction financing.

     In connection with the Wellsford Merger, the Operating Partnership has
provided a standby obligation in the amount of $30 million pursuant to an
agreement entered into with Wellsford Real Properties, Inc., a Maryland
corporation ("WRP"), for the construction financing for a multifamily
development project located in Denver, Colorado.  In addition, the Operating
Partnership has provided a $14.8 million credit enhancement with respect to
bonds issued to finance certain public improvements at the multifamily
development project.
