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"), Evans Withycombe Residential, Inc. ("EWR") (the "EWR Merger") and
Merry Land & Investment Company, Inc. ("MRY") (the "MRY Merger") (collectively,
the "Mergers").

     The Operating Partnership's subsidiaries include 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, and Merry Land DownREIT I LP.

     As of December 31, 1998, the Operating Partnership owned or had interests
in 681 multifamily properties of which it controlled a portfolio of 654
multifamily properties (individually, a "Property" and collectively, the
"Properties") containing 187,002 units. The remaining 27 properties represent an
investment in partnership interests and subordinated mortgages collateralized by
21 properties containing 3,896 units and an investment in six joint ventures
consisting of six properties containing 1,297 units (collectively, the
"Additional Properties"). 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 52 properties containing 12,890 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 the Company's outstanding Common Shares) and is one of the
largest publicly traded REIT owner of multifamily properties (based on the
number of apartment units wholly-owned and total revenues earned).

     Since the EQR IPO and through December 31, 1998, the Operating Partnership
has acquired direct or indirect interests in 650 properties (which included the
debt collateralized by six Properties) containing 180,224 units in the aggregate
for a total purchase price of approximately $10.6 billion, including the
assumption of approximately $2.6 billion of mortgage indebtedness and $845.9
million of unsecured notes. Since the EQR IPO and through December 31, 1998, the
Operating Partnership has disposed of 38 properties and a portion of one
Property, containing 9,754 units, and a vacant land parcel for a total sales
price of approximately $306.8 million.

     The Company's corporate headquarters and executive offices are located in
Chicago, Illinois. In


                                       4
<PAGE>
 
                                    PART I

addition, the Operating Partnership has 30 management offices in the following
cities:

   . Chicago, Illinois;
   . Dallas, Houston and San Antonio, Texas;
   . Denver, Colorado;
   . Bethesda, Maryland;
   . Atlanta and Augusta, Georgia;
   . Las Vegas, Nevada;
   . Scottsdale and Tucson, Arizona;
   . Portland, Oregon;
   . Ypsilanti, Michigan;
   . Charlotte and Raleigh, North Carolina;
   . Tampa, Jacksonville, Ft. Lauderdale and Orlando, Florida;
   . Irvine, Pleasant Hill and Stockton, California;
   . Kansas City, Kansas;
   . Minneapolis, Minnesota;
   . Louisville, Kentucky;
   . Tulsa, Oklahoma;
   . Seattle and Redmond, Washington; and
   . Nashville and Memphis, Tennessee.

The Operating Partnership has approximately 6,000 employees. An on-site manager,
who supervises the on-site employees and is responsible for the day-to-day
operations of the Property, directs each of the Operating Partnership's
Properties. A leasing administrator and/or property administrator generally
assists the manager. 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: (a) the value of the Properties; (b)
distributions on a per limited partnership interest ("OP Unit") basis; and (c)
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:
     a)  are available at prices below estimated replacement costs;
     b)  have potential for rental rate and/or occupancy increases;
     c)  have attractive locations in their respective markets;
     d)  provide anticipated total returns that will increase the Operating
         Partnership's distributions per OP Unit; and
   . 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


                                       5
<PAGE>
 
                                    PART I

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:
     .   the geographic area and type of community;
     .   the location, construction quality, condition and design of the
         property;
     .   the current and projected cash flow of the property and the ability to
         increase cash flow;
     .   the potential for capital appreciation of the property;
     .   the terms of resident leases, including the potential for rent
         increases;
     .   the potential for economic growth and the tax and regulatory
         environment of the community in which the property is located;
     .   the occupancy and demand by residents for properties of a similar type
         in the vicinity (the overall market and submarket);
     .   the prospects for liquidity through sale, financing or refinancing of
         the property;
     .   the benefits of integration into existing operations; and
     .   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 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:

     .   income levels and employment growth trends in the relevant market;
     .   uniqueness of location;
     .   household growth and net migration of the relevant market's population;


                                       6
<PAGE>
 
                                    PART I

   . supply/demand ratio, competitive housing alternatives, sub-market occupancy
     and rent levels;
   . barriers to entry that would limit competition; and
   . the purchase prices and yields of available existing stabilized
     communities, if any.

Disposition Strategies

     Management will use market information to evaluate dispositions. Factors
the Operating Partnership considers in deciding whether to dispose of its
Properties include the following:

   . potential increases in new construction;
   . areas where the economy is expected to decline substantially; and
   . 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 may 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 business activities conducted by the Operating
Partnership and its susidiaries.

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%

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 (which is referred to herein as the
"Dividend Reinvestment - DRIP Plan"). 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) (which is referred to herein as the
"Share Purchase - DRIP Plan"). The proceeds from sales were contributed to the 
Operating Partnership in exchange for OP Units.

Recent Transactions

     From January 1, 1999 through March 12, 1999, the Operating Partnership
acquired three Properties from an affiliated party and two Properties from
unaffiliated third parties for a total purchase price of approximately $86.6
million, which included the assumption of mortgage indebtedness of approximately
$16.9 million. The three Properties acquired from an affiliated party were Aspen
Crossing, a 192-unit property located in Wheaton, Maryland; Fireside Park, 
a 236-unit property located in Rockville, Maryland; and Mill Pond, a 240-unit
property located in Glen Burnie, Maryland. The two Properties acquired from
unaffiliated third parties were Copper Canyon, a 222-unit property located in
Denver, Colorado; and Siena Terrace, a 356-unit property located in Lake Forest,
California.

     From January 1, 1999 through March 12, 1999, the Operating Partnership
disposed of six Properties for a total sales price of $64 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.

securities together as our "securities," and the investors who own Units and/or
debt securities as our "security holders."

Debt Financing and Preferred Shares Could Adversely Affect Our Performance

     General

     As of December 31, 1998, our multifamily properties were subject to
approximately $2.3 billion of mortgage indebtedness and our total debt equaled
approximately $4.7 billion. Of our total debt outstanding, $840 million
(including the balance of $290 million outstanding on our $620 million unsecured
lines of credit) was floating rate debt, which included $684.7 million issued at
tax exempt rates. In addition to debt, Equity Residential Properties Trust, our
general partner, has issued preferred shares of beneficial interest and
depositary shares. The use of debt and preferred equity financing creates
certain risks, including the following.

     Scheduled Debt Payments Could Adversely Affect Our Financial Condition

     In the future, our cash flow could be insufficient to pay distributions on
our securities at expected levels and to meet required payments of principal and
interest. We may not be able to refinance existing debt (which in virtually all
cases requires substantial principal payments at maturity) and, if we can, the
terms of such refinancing might not be as favorable as the terms of our existing
indebtedness. If principal payments due at maturity cannot be refinanced,
extended or paid with proceeds of other capital transactions, such as our
general partner raising new equity capital, our cash flow will not be sufficient
in all years to repay all maturing debt. As a result, we may be forced to
postpone capital expenditures necessary for the maintenance of our properties
and may have to dispose of one or more properties on terms that would otherwise
be unacceptable to us.

     Financial Covenants Could Adversely Affect Our Financial Condition

     If a property we own is mortgaged to secure payment of indebtedness and we
are unable to meet the mortgage payments, the holder of the mortgage could
foreclose on the property, resulting in loss of income and asset value.
Foreclosure on our mortgaged properties or an inability to refinance existing
indebtedness would likely have a negative impact on our financial condition and
results of operations. A foreclosure could also result in our recognition of
taxable income without our actually receiving cash proceeds from the disposition
of the property with which to pay the tax. This would adversely affect our cash
flow and would make it more difficult for us to service our debt and make
distributions to security holders.

     The mortgages on our properties contain customary negative covenants which,
among other things, limit our ability, without the prior consent of the lender,
to further mortgage the property, to enter into new leases or materially modify
existing leases and to discontinue insurance coverage. In addition, our credit
facilities contain certain customary restrictions, requirements and other
limitations on our ability to incur indebtedness. The indentures under which a
substantial portion of our debt was issued contain certain financial and
operating covenants including, among other things, certain financial ratios, as
well as limitations on our ability to incur secured and unsecured indebtedness
(including acquisition financing), sell all or substantially all of our assets
and engage in mergers, consolidations and certain acquisitions. Accordingly, in
the event that we are unable to raise additional equity or borrow money because
of these restrictions, our ability to acquire additional properties may be
limited. Our inability to acquire additional properties may limit our
management's ability to increase funds from operations, and thereby cash
available to service debt and make distributions to security holders.

                                       15
<PAGE>
 
                                    PART I

     Some of our properties were financed with tax-exempt bonds that contain
certain restrictive covenants or deed restrictions. We have retained an
independent outside consultant to monitor compliance with the restrictive
covenants and deed restrictions that affect these properties. If these bond
compliance requirements require us to lower our rental rates to attract low or
moderate income tenants, or eligible/qualified tenants, then our income from
these properties may be limited.

     Our Degree of Leverage Could Limit Our Ability to Obtain Additional
     Financing

     The debt to market capitalization ratio (total debt as a percentage of
total debt plus the market value of the outstanding common and preferred shares
of beneficial interest and Units) of our general partner and its subsidiaries
(including us) was approximately 41% as of December 31, 1998. We have a policy
of incurring indebtedness for borrowed money only if upon such incurrence this
debt to market capitalization ratio would be approximately 50% or less. Our
degree of leverage could have important consequences to security holders. For
example, the degree of leverage could affect our ability to obtain additional
financing in the future for working capital, capital expenditures, acquisitions,
development or other general corporate purposes, making us more vulnerable to a
downturn in business or the economy generally.

     Rising Interest Rates Could Adversely Affect Cash Flow

     Advances under our credit facilities bear interest at variable rates based
upon one, two, three or six month LIBOR, plus a certain spread dependent upon
the Operating Partnership's credit rating. Certain of our senior unsecured debt
instruments also, from time to time, bear interest at floating rates. We may
also borrow additional money with variable interest rates in the future.
Increases in interest rates would increase our interest expenses under these
debt instruments and would increase the costs of refinancing existing
indebtedness and of issuing new debt. Accordingly, higher interest rates would
adversely affect cash flow and our ability to service our debt and to make
distributions to security holders.

Environmental Problems are Possible and Can be Costly

     Federal, state and local laws and regulations relating to the protection of
the environment may require a current or previous owner or operator of real
estate to investigate and clean up hazardous or toxic substances or petroleum
product releases at such property. The owner or operator may have to pay a
governmental entity or third parties for property damage and for investigation
and clean-up costs incurred by such parties in connection with the
contamination. These laws typically impose clean-up responsibility and liability
without regard to whether the owner or operator knew of or caused the presence
of the contaminants. Even if more than one person may have been responsible for
the contamination each person covered by the environmental laws may be held
responsible for all of the clean-up costs incurred. In addition, third parties
may sue the owner or operator of a site for damages and costs resulting from
environmental contamination emanating from that site.

     Environmental laws also govern the presence, maintenance and removal of
asbestos. These laws require that owners or operators of buildings containing
asbestos properly manage and maintain the asbestos, that they notify and train
those who may come into contact with asbestos and that they undertake special
precautions, including removal or other abatement, if asbestos would be
disturbed during renovation or demolition of a building. These laws may impose
fines and penalties on building owners or operators who fail to comply with
these requirements and may allow third parties to seek recovery from owners or
operators for personal injury associated with exposure to asbestos fibers.

     All of our properties have been the subject of a Phase I, and in certain
cases a supplemental, environmental assessment completed by qualified
independent environmental consultant companies. Environmental assessments were
obtained prior to our acquisition of each of our properties. These

                                    PART I

environmental assessments have not revealed, nor are we aware of, any
environmental liability that our management believes would have a material
adverse effect on our business, results of operations, financial condition or
liquidity.

     We cannot assure you that existing environmental assessments of our
properties reveal all environmental liabilities, that any prior owner of any of
our properties did not create a material environmental condition not known to
us, or that a material environmental condition does not otherwise exist as to
any one or more of our properties.

Our Ability to Service Debt and Make Distributions to Security Holders is
Subject to Risks Associated With the Real Estate Industry

     General

     Real property investments are subject to varying degrees of risk and are
relatively illiquid. Several factors may adversely affect the economic
performance and value of our properties. These factors include changes in the
national, regional and local economic climate, local conditions such as an
oversupply of multifamily properties or a reduction in demand for our
multifamily properties, the attractiveness of our properties to tenants,
competition from other available multifamily property owners and changes in
market rental rates. Our ability to service our debt and make distributions to
security holders also depends on our ability to collect rent from tenants and to
pay for adequate maintenance, insurance and other operating costs, including
real estate taxes, which could increase over time. Also, the expenses of owning
and operating a property are not necessarily reduced when circumstances such as
market factors and competition cause a reduction in income from the property.

     We May be Unable to Renew Leases or Relet Space as Leases Expire

     When our tenants decide not to renew their leases upon expiration, we may
not be able to relet their space. Even if the tenants do renew or we can relet
the space, the terms of renewal or reletting may be less favorable than current
lease terms. If we are unable to promptly renew the leases or relet the space,
or if the rental rates upon renewal or reletting are significantly lower than
expected rates, then our results of operations and financial condition will be
adversely affected. Consequently, our cash flow and ability to service debt and
make distributions to security holders would be reduced.

     New Acquisitions or Developments May Fail to Perform as Expected and
     Competition for Acquisitions May Result in Increased Prices for Properties

     We intend to continue to actively acquire or develop multifamily
properties. Newly acquired or developed properties may fail to perform as
expected. We may underestimate the costs necessary to bring an acquired property
up to standards established for its intended market position or to develop a
property. Additionally, we expect other major real estate investors with
significant capital will compete with us for attractive investment
opportunities. This competition has increased prices for multifamily properties.
We may not be in a position or have the opportunity in the future to make
suitable property acquisitions on favorable terms.

     Because Real Estate Investments Are Illiquid, We May Not Be Able To Sell
     Properties When Appropriate

     Real estate investments generally cannot be sold quickly. We may not be
able to vary our portfolio promptly in response to economic or other conditions.
This inability to respond promptly to changes in the performance of our
investments could adversely affect our financial condition and ability to
service our debt and make distributions to our security holders.

                                    PART I

     Changes in Laws Could Affect Our Business

     We are generally not able to pass through to our tenants under existing
leases increases in real estate taxes, income taxes and service or other taxes.
Consequently, any such increases may adversely affect our financial condition
and limit our ability to service our debt and make distributions to our security
holders. Similarly, changes that increase our potential liability under
environmental laws or our expenditures on environmental compliance would
adversely affect our cash flow and ability to service our debt and make
distributions on our securities.

We Depend on Our Key Personnel

     We depend on the efforts of the executive officers of our general partner,
particularly Samuel Zell and Douglas Crocker II. If they resign, our operations
could be temporarily adversely effected. Neither Mr. Crocker nor Mr. Zell has
entered into an employment agreement with our general partner.

Our General Partner's Compliance with Real Estate Investment Trust (REIT)
Distribution Requirements May Affect Our Financial Condition

     Distribution Requirements May Increase the Indebtedness of the Company

     We 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 our repayment of principal on debt, we could have taxable
income without sufficient cash to enable our general partner to meet the
distribution requirements of a REIT. Accordingly, we could be required to borrow
funds or liquidate investments on adverse terms in order to meet such
distribution requirements.

     We Are Dependent on External Sources of Capital

     Because of our general partner's annual REIT distribution requirements, it
is not likely that we will be able to fund all future capital needs, including
for acquisitions, from income from operations. We therefore will have to rely on
third-party sources of capital, which may or may not be available on favorable
terms or at all. Our access to third-party sources of capital depends on a
number of things, including the market's perception of our growth potential and
our current and potential future earnings. Moreover, additional debt financing
may substantially increase our leverage.

Item 2. The Properties

     As of December 31, 1998, the Operating Partnership controlled a portfolio
of 654 multifamily Properties, of which six are under development, located in 35
states containing 187,002 apartment units, of which 2,107 units pertain to the
development Properties. The average number of units per Property, not including
the development Properties, was approximately 285. The units are typically
contained in a series of two-story buildings. The Properties contain an
aggregate of 166.1 million rentable square feet, with an average unit size of
898 square feet (not including the development Properties). The average rent per
unit was $739 and the average rent per square foot was $0.82 (not including the
development Properties).

     As of December 31, 1998, 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.

                                       18

                                    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 647 of the
Properties and holds a 99-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 benefit of 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, 1998, the Operating Partnership had an investment in
partnership interests and subordinated mortgages collateralized by 21 of the
Additional Properties and an investment in six joint ventures consisting of six
of the Additional Properties. The Additional Properties contain 5,193 units,
located in six states.

     The following tables include only those Properties and Additional
Properties owned by the Operating Partnership or in which the Operating
Partnership had a direct equity or mortgage interest at December 31, 1998. As
such, the properties currently under development by third parties (see
discussion in Item 7) are not included in the following tables. In addition, the
units for expansion properties are not included in the following tables until
the expansion is complete.

     The following tables set forth certain information relating to the
Properties, Properties under development and the Additional Properties:

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 5.   Market for Registrant's Common Equity and Related Shareholder Matters

          There is no established public trading market for the OP Units.

          During 1998, the Operating Partnership directly issued 4,235,685 OP
Units having a value of $205.2 million and 48,328 Junior Convertible Preference
Units having a value of $4.8 million in exchange for direct or indirect
interests in multifamily Properties in private placement transactions under
section 4(2) of the Securities Exchange Act of 1934, as amended. OP Units are
exchangeable into Common Shares of the Company on a one-for-one basis or, at the
option of the Company, the cash equivalent thereof one year from the date of 
issuance.

          The following tables sets forth, for the periods indicated, the
distributions paid on the Operating Partnership's OP Units:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

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

(1)  Includes approximately $96.3 million and $36 million of construction in
     progress as of December 31, 1998 and 1997, respectively.

(2)  In August 1995 the Operating Partnership also made its $89 million mortgage
     note investment collateralized by 21 of the Additional Properties. In April
     1997, the Operating Partnership made its $88 million mortgage note
     investment collateralized by five of the Additional Properties. In 1998,
     these properties were acquired and are no longer included as Additional
     Properties, but now are included as Properties. In addition, in October
     1998, the Operating Partnership contributed six of the Additional
     Properties having a value of $52.7 million to six respective joint
     ventures. These 27 Additional Properties consisted of 5,193 units at
     December 31, 1998. These 26 Additional Properties consisted of 5,267 units
     at December 31, 1997. The Additional Properties are not included in these
     numbers.

(3)  The Operating Partnership generally considers FFO to be one measure of the
     performance of real estate companies, including an equity REIT. 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 an equity REIT 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, 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 REIT's and, accordingly, may not be comparable to such
     other REIT's. The Operating Partnership's calculation of FFO for 1995 and
     1994 has 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.

                    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 Management Partnerships, the Financing
Partnerships and the LLCs, and Merry Land DownREIT I LP, 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:

  .  alternative sources of capital to the Operating Partnership are higher than
     anticipated;
  .  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 this 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 EQR's IPO and through December 31, 1998, the Operating Partnership
has acquired direct interests in 623 properties, of which six are under
development, (the "Acquired Properties"), containing 175,031 units in the
aggregate for a total purchase price of approximately $10.4 billion, including
the assumption of approximately $2.6 billion of mortgage indebtedness and $845.9
million 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 Acquired Properties are presented in the Consolidated 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 mortgage note investment collateralized by 21
of the Additional Properties and in October 1998, the Operating Partnership
contributed 6 of the Additional Properties having a value of $52.7 million to
six joint ventures.

     The following table summarizes the number of Acquired Properties and

     From the IPO and through December 31, 1998, the Operating Partnership
disposed of 38 Properties and a portion of one Property, including five
properties containing 1,254 units during 1996 (the "1996 Disposed Properties");
seven properties, a portion of one property and a vacant land parcel containing
1,336 units during 1997 (the "1997 Disposed Properties"); and twenty properties
containing 4,719 units during 1998 (the "1998 Disposed Properties").

     The Operating Partnership's overall results of operations for the three
years ended December 31, 1998 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 1998 and
1997 (the "1998 Same Store Properties") and Properties that the Operating
Partnership owned for all of both 1997 and 1996 (the "1997 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, 1998 to the year ended December
     31, 1997

     For the year ended December 31, 1998, income before gain on disposition of
properties and extraordinary item increased by $79 million when compared to the
year ended December 31, 1997. 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 expense,
interest expense and general and administrative expenses.

     In regard to the full year 1998 Same Store Properties, which represents
63,243 units, rental income increased by approximately $23.1 million to $527.3
million or 4.59% primarily as a result of higher rental rates charged to new
tenants and tenant renewals, a 1.01% increase in average economic occupancy
levels and an increase in income from billing tenants for their share of utility
costs. Overall, property operating expenses, which include property and
maintenance, real estate taxes and insurance and an allocation of property
management expenses increased approximately $5.3 million or 2.65%. This increase
was primarily the result of higher compensation costs, leasing and advertising
costs, utilities, and maintenance charges.

                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Results of Operations (Continued)

     Property management represents expenses associated with the self-management
of the Operating Partnership's Properties. These expenses increased by
approximately $25.9 million primarily due to the continued expansion of the
Operating Partnership's property management business. The 1998 amounts include a
full year effect of the various offices the Operating Partnership opened in
1997, including the Scottsdale Office, which had a significant expansion
resulting from the EWR Merger. During 1998, the Operating Partnership opened new
management offices in Jacksonville and Orlando, Florida and the Operating
Partnership assumed a management office in Augusta, Georgia, related to the MRY
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 net revenues decreased by
$0.9 million 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 $125.5 million. This increase was primarily the
result of an increase in the Operating Partnership's average indebtedness
outstanding which increased by $1.9 billion. However, the Operating
Partnership's effective interest costs decreased from 7.50% for the year ended
December 31, 1997 to 7.10% for the year ended December 31, 1998.

     General and administrative expenses, which include corporate operating
expenses, increased approximately $6.7 million between the periods under
comparison. This increase was primarily due to the addition of corporate
personnel in the Operating Partnership's Human Resources, Accounting, Legal and
Management Information Systems groups, as well as higher compensation costs,
shareholder reporting costs and professional fees. However, by gaining certain
economies of scale with a much larger operation these expenses as a percentage
of total revenues were 1.62% for the year ended December 31, 1998 compared to
2.02% of total revenues for the year ended December 31, 1997.

     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 item 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, which represents 49,805 units,
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.
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. In addition, the Operating Partnership was successful in reducing
its costs for leasing and advertising as well as building, maintenance and
grounds costs by consolidating its vendor services in selected sub-markets in
order to obtain volume pricing discounts and by

Results of Operations (Continued)

consolidating its personnel in selected sub-markets 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; 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 net revenues decreased by
$0.6 million 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.

Liquidity and Capital Resources

For the Year Ended December 31, 1998

     As of January 1, 1998, the Operating Partnership had approximately $33.3
million of cash and cash equivalents and $265 million available on its line of
credit of which $24.7 million was restricted. After taking into effect the
various transactions discussed in the following paragraphs, cash and cash
equivalents at December 31, 1998 were approximately $4 million and the amounts
available on the Operating Partnership's lines of credit were $330 million of
which $12 million was 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, funding its Properties in the development stage and the
funding of the Operating Partnership's investment in a joint venture with a
multifamily real estate developer, 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 or the disposition of
Properties. Utilizing this strategy during 1998 the Company and/or the Operating
Partnership:

  .  issued a total of approximately 8.5 million Common Shares through various
     offerings and received total net proceeds of $412.5 million, which were
     contributed by the Company to the Operating Partnership in exchange for OP
     Units.
  .  issued the 2015 Notes, the August 2003 Notes and the 2000 Notes and
     received net proceeds of $542.3 million;
  .  mortgaged fifteen previously unencumbered Properties and received net
     proceeds of $223.5 million; and
  .  disposed of twenty properties, which generated net proceeds of
     approximately $177 million.

All of these proceeds were utilized to either:
  .  purchase additional properties;
  .  provide funding for properties in the development stage; and/or
  .  repay the lines of credit and mortgage indebtedness on certain Properties.

     With respect to the 1998 Acquired Properties, the Company issued 21.8
million Common Shares having a value of $1.0 billion and issued the following
preferred shares having a combined liquidation value of $369.1 million (upon
contribution of the net assets by the Company to the Operating Partnership, the
Operating Partnership issued OP Units and cumulative convertible or redeemable
preference units to the Company):

  .  Series H Preferred Shares;
  .  Series I Preferred Shares;
  .  Series J Preferred Shares;
  .  Series K Preferred Shares; and
  .  Series L Preferred Shares.

     The Operating Partnership also assumed mortgage indebtedness, unsecured
notes and a line of credit of approximately $1.2 billion, issued OP Units having
a value of approximately $205.2 million and issued Junior Convertible Preference
Units having a value of approximately $4.8 million. The cash portion of these
acquisitions were primarily funded from amounts drawn on the Operating
Partnership's lines of credit and proceeds received in connection with the
transactions mentioned in the previous paragraphs.

     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. During 1997 and 1998, the Operating Partnership
funded a total of $6.9 million and $23.9 million and during 1999 the Operating
Partnership expects to fund approximately $74.9 million in connection with this
agreement. Subsequent to December 31, 1998, the Operating Partnership has funded
approximately $1 million. In addition, the Operating Partnership also funded $20
million to guarantee third party construction financing and is obligated to fund
up to an additional $20 million.

     In regards to certain other properties under development and/or expansion
in 1998, the Operating Partnership funded $31.6 million. In 1999, the Operating
Partnership expects to fund $53.9 million related to the continued development
and/or expansion of as many as five Properties.

                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Liquidity and Capital Resources (Continued)

     In regards to certain properties having earnout/development agreements, in
1998 no amounts were funded. The Operating Partnership expects to fund $60.4
million related to three earnout/development projects expected to be finished
during 1999. Subsequent to December 31, 1998, the Operating Partnership has
funded $16.2 million relating to the completion/acquisition of Copper Canyon. In
addition, the Operating Partnership may be required to fund an additional $1
million earnout payment to the developer for Copper Canyon if certain specified
operation levels are met.

     As of December 31, 1998, the Operating Partnership had total indebtedness
of approximately $4.7 billion, which included mortgage indebtedness of $2.3
billion (including premiums of $4.5 million), of which $878.3 million
represented tax-exempt bond indebtedness, and unsecured debt of $2.3 billion
(net of a $5.3 million discount), of which $35.6 million represented tax-exempt
bond indebtedness. During the year, the Operating Partnership repaid an
aggregate of $63.8 million of mortgage indebtedness on nine of its Properties.
These repayments were funded from the Operating Partnership's credit facilities
or from proceeds received from the various capital transactions mentioned in the
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 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. No such financial
instrument has been used for trading purposes.

     In February 1996, the Operating Partnership entered into a Forward Starting
Swap agreement that will hedge the Operating Partnership's interest rate risk at
maturity of $125 million of indebtedness. This agreement hedged the interest
rate risk of the Operating Partnership's 1999 Notes by locking the effective
four-year Treasury Rate commencing May 15, 1999.

     In August 1996, the Operating Partnership entered into an interest rate
protection agreement to effectively fix the interest rate cost of the Operating
Partnership's 2026 Notes. The agreement was for a notional amount of $150
million with a locked in treasury rate of 7.57%.

     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 of 6.134%. The second agreement
was for a notional amount of $75 million with a locked in treasury rate of
6.287%.

     In April 1998, the Operating Partnership entered into an interest rate
protection agreement to effectively fix the interest rate cost of the Operating
Partnership's 2015 Notes. The agreement was for a notional amount of $300
million with a locked in treasury rate of 6.63%.

     In May 1998, the Operating Partnership entered into an interest rate
protection agreement to effectively fix the interest rate cost of the Evans
Withycombe Financing Limited Partnership indebtedness to within a range of 5.6%
to 6.0% upon its refinancing. The agreement was for a notional amount of $131
million with a settlement date of August 2001. There was no initial cost to the
Operating Partnership for entering into this agreement.

     In August 1998, the Operating Partnership entered into an interest rate
protection agreement to effectively fix the interest rate cost of the Operating
Partnership's planned financing in the fourth quarter of

                                       52

1998. This agreement was cancelled in November at a cost of approximately $3.7
million. This cost is being amortized over the life of the financing for the 15
previously unencumbered Properties that occurred in November 1998.

     In August 1998, the Operating Partnership entered into an interest rate
swap agreement that fixed the Operating Partnership's interest rate risk on a
portion of the Operating Partnership's variable rate tax-exempt bond
indebtedness at a rate of 3.65125%. This agreement was for a notional amount of
$150 million with a termination date of August 2003.

     In August 1998, the Operating Partnership entered into an interest rate
swap agreement that fixed the Operating Partnership's interest rate risk on a
portion of the Operating Partnership's variable rate tax-exempt bond
indebtedness at a rate of 3.683%. This agreement was for a notional amount of
$150 million with a termination date of August 2005.

     The fair value of these instruments, discussed above, as of December 31,
1998 approximates 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 replacement-type items
described above, the Operating Partnership generally expects to spend $250 per
unit on an annual recurring basis.

     During the year ended December 31, 1998, total capital expenditures for the
Operating Partnership approximated $102 million. Of this amount, approximately
$34.1 million related to capital improvements and major repairs for the 1996,
1997 and 1998 Acquired Properties. Capital improvements and major repairs for
all of the Operating Partnership's pre-EQR IPO properties and 1993, 1994 and
1995 Acquired Properties approximated $17.1 million, or $338 per unit. Capital
spent for replacement-type items approximated $39.4 million, or $257 per unit,
which is in line with the Operating Partnership's expected annual recurring per
unit cost. Also included in total capital expenditures was approximately $11.4
million expended for non-real estate additions such as computer software,
computer equipment, and 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 1999 are budgeted to be approximately $110 million for
all properties or $588 per unit.

     Total distributions paid in 1998 amounted to $404.5 million, which included
certain distributions declared in the fourth quarters of 1997 and 1998. The
Operating Partnership paid a $0.71 per OP Unit distribution on December 31, 1998
for the quarter ended December 31, 1998 to OP Unit holders of record as of
December 20, 1998.

     Subsequent to December 31, 1998 and through March 12, 1999, the Operating
Partnership acquired five additional properties representing 1,246 units for a
total purchase price of approximately $86.6 million, including the assumption of
approximately $16.9 million of mortgage indebtedness. These acquisitions were
primarily funded from the proceeds obtained from the sale of certain Properties
in 1998 and 1999. The Operating Partnership is always seeking to acquire
additional multifamily properties with physical and market characteristics
similar to the Properties.

     Subsequent to December 31, 1998 and through March 12, 1999, the Operating
Partnership disposed of six Properties for a total sales price of $64 million.
These proceeds will be utilized to purchase additional Properties. The Operating
Partnership anticipates that it will continue to sell certain Properties in the
portfolio.

     The Operating Partnership expects to meet its short-term liquidity
requirements, including capital expenditures relating to maintaining its
existing Properties and the funding of Properties in the development stage,
generally through its working capital, net cash provided by operating activities
and borrowings under its lines 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 lines 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 Company or the Operating Partnership or the cost of
alternative sources of capital to the Operating Partnership is too high.

     The Operating Partnership has a revolving credit facility with Morgan
Guaranty and Bank of America (as co-agents) to provide the Operating
Partnership with potential borrowings of up to $500 million. This credit
facility matures in November 1999 and will continue to be used to fund property
acquisitions and short term liquidity requirements. As of March 12, 1999, $145
million was outstanding under this facility.

     In connection with the MRY Merger, the Operating Partnership assumed a
second revolving credit facility with First Union Bank (as agent) with
potential borrowings of up to $120 million. This credit facility matures in
September 2000 and will also be used to fund property acquisitions, costs for
certain Properties under development and short term liquidity requirements. As
of March 12, 1999, $35 million was outstanding under this facility.

     In connection with the Wellsford Merger the Operating Partnership provided
a $14.8 million credit enhancement with respect to bonds issued to finance
certain public improvements at a multifamily development project. Pursuant to
the terms of a Stock Purchase Agreement with Wellsford Real Properties, Inc.
("WRP Newco"), the Operating Partnership will agree to purchase up to 1,000,000
shares of WRP Newco Series A Preferred at $25.00 per share over a three-year
period ending on May 30, 2000. As of March 12, 1999, no shares of WRP Newco
Series A Preferred had been acquired by the Operating Partnership.

     In conjunction with the MRY Merger in October 1998, the Operating
Partnership entered into six joint venture agreements with MRYP Spinco, the
entity spun-off in the MRY Merger. The Operating

Partnership contributed six properties with an initial value of $52.7 million in
return for a 50% ownership interest in each joint venture. In return for the
spin-off of certain assets and liabilities to MRYP Spinco, the Operating
Partnership received (from MRYP Spinco) a Subordinated Note receivable totaling
$20 million, a preferred stock investment with an initial value of $5 million
and a $25 million, one year, non-revolving Senior Note receivable. At December
31, 1998 approximately $18.3 million was outstanding on the Senior Note, bearing
interest at LIBOR plus 250 basis points. The Operating Partnership has a
potential obligation to fund up to an additional $6.7 million under the Senior
Note.

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 were
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. Utilizing this
strategy during 1997 the Company and/or the Operating Partnership:

  .  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,
     which were contributed by the Company to the Operating Partnership in 
     exchange for OP Units;
  .  completed the offerings of the Series D Preferred Shares and the Series G
     Preferred Shares and received net proceeds of approximately $473.1 
     million, which were contributed by the Company to the Operating Partnership
     in exchange for cumulative redeemable preference units and cumulative 
     convertible preference units, respectively; and
  .  issued the 2017 Notes, the 2001 Notes and the 2003 Notes and received net
     proceeds of approximately $345.9 million.

     With respect to Property acquisitions during 1997, 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 issuance's of 25.1 million Common Shares (which were contributed by the
Company to the Operating Partnership in exchange for OP Units), 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 (which were contributed by the Company to the
Operating Partnership in exchange for cumulative convertible preference units
and cumulative redeemable preference units, respectively), 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.

                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

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, the $100 million of floating
rate notes due December 22, 1997 were repaid at maturity. 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, 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
approximately $9.7 million expended for non real estate additions such as
computer software, computer equipment, and 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.

Year 2000 Issue

     The year 2000 issue ("Year 2000") is the result of computer programs being
written using two digits rather than four to define the applicable year. Any of
the Operating Partnership's computer programs that have time-sensitive hardware
and software may recognize a date using "00" as the year 1900 rather than the
year 2000. This could result in a system failure or miscalculations causing
disruptions of operations, including, among other things, a temporary inability
to process transactions, collect rents, or engage in similar normal business
activities.

     The Operating Partnership believes that it has identified all of its
information technology ("IT") and non-IT systems to assess their Year 2000
readiness. Critical systems include, but are not limited to: accounts receivable
and rent collections, accounts payable and general ledger, human resources and
payroll (both property and corporate levels), cash management, fixed assets, all
IT hardware (such as desktop/laptop computers, data networking equipment,
telephone systems, fax machines, copy machines, etc.) and software, and property
environmental, health safety and security systems (such as elevators and alarm
systems).

     The Operating Partnership anticipates that previously scheduled system
upgrades to many of its IT systems will remediate any existing Year 2000
problems. The Operating Partnership is currently in the process of testing and
implementing the majority of its Year 2000 IT and non-IT system projects with
completion anticipated during the second or third quarter of 1999. The Operating
Partnership has estimated that the total Year 2000 project cost will approximate
$1 million, of which approximately 70% has been incurred as of December 31,
1998. During the fourth quarter of 1998, the primary focus of the Year 2000
remediation efforts was on testing and implementing existing and new IT systems
and on assessing the Operating Partnership's exposure regarding non-IT systems
at property sites. Of the remaining $300,000 budgeted to complete the Operating
Partnership's Year 2000 remediation project, approximately $150,000 has been
allocated to engage Year 2000 consultants to help the Operating Partnership
monitor its

                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Year 2000 Issue (Continued)

IT compliance progress and to complete final IT testing and implementation. The
remaining $150,000 has been allocated to remediate non-IT systems at various
property sites. The estimates are based on management's best estimates, which
were derived utilizing numerous assumptions of future events, and there can be
no guarantees that these estimates will be achieved.

     In some cases, various third party vendors have been queried on their Year
2000 readiness. The Operating Partnership continues to query its significant
suppliers and vendors 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. To date, the Operating Partnership is
not aware of any significant suppliers or vendors with a Year 2000 issue that
would materially impact the Operating Partnership's results of operations,
liquidity, or capital resources. However, there can be no assurances that the
systems of other companies, on which the Operating Partnership's systems rely,
will be timely converted and would not have an adverse effect on the Operating
Partnership's systems.

     Management of the Operating Partnership believes it has an effective
program in place to resolve the Year 2000 issue in a timely manner. In addition,
the Operating Partnership has commenced its contingency planning for critical
operational areas that might be affected by the Year 2000 issue if compliance by
the Operating Partnership is delayed. Aside from catastrophic failure of banks
or governmental agencies, the Operating Partnership believes that it could
continue its normal business operations if compliance by the Operating
Partnership is delayed. The Operating Partnership does not believe that the Year
2000 issue will materially impact its results of operations, liquidity or
capital resources.

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 deferring financing
costs and depreciation of non-real estate assets 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 Operating Partnership 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 and amortization of
deferred financing costs related to EQR's Predecessor Business less an
allocation of net income to preference unit holders. The

Funds From Operations (Continued)

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, 1998, FFO increased $188.1 million
representing a 69.5% increase when compared to the year ended December 31, 1997.
For the year ended December 31, 1997, FFO increased by $110.5 million
representing a 69% increase when compared to the year ended December 31, 1996.

     The following is a reconciliation of net income to FFO for the years ended
December 31, 1998, 1997 and 1996 (amounts are in thousands):

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Item 7A. Quantitative and Qualitative Disclosure About Market Risk

     The Operating Partnership's future earnings, cash flows and fair values
relevant to financial instruments are dependent upon prevalent market rates.
Market risk is the risk of loss from adverse changes in market prices and
interest rates. The Operating Partnership manages its market risk by matching
projected cash inflows from operating properties, financing activities and
investing activities with projected cash outflows to fund debt payments,
acquisitions, capital expenditures, distributions and other cash requirements.
The Operating Partnership also utilizes certain derivative financial instruments
to limit market risk. Interest rate protection agreements are used to convert
floating rate debt to a fixed rate basis. Derivatives are used for hedging
purposes rather than speculation. The Operating Partnership does not enter into
financial instruments for trading purposes.

     The Operating Partnership has total outstanding debt of approximately $4.7
billion at December 31, 1998, of which approximately $840 million, or 18%, is
floating rate debt, including the effects of any interest rate protection
agreements. If market rates of interest on the Operating Partnership's floating
rate debt increase by 54 basis points (a 10% increase), the increase in interest
expense on the Operating Partnership's floating rate debt would decrease future
earnings and cash flows by approximately $4.5 million. If market rates of
interest on the Operating Partnership's floating rate debt decrease by 54 basis
points (a 10% increase), the decrease in interest expense on the Operating
Partnership's floating rate debt would increase future earnings and cash flows
by approximately $4.5 million.

     These amounts were determined by considering the impact of hypothetical
interest rates on the Operating Partnership's financial instruments. These
analyses do not consider the effects of the reduced level of overall economic
activity that could exist in such an environment. Further, in the event of a
change of such magnitude, management would likely take actions to further
mitigate its exposure to the change. However, due to the uncertainty of the
specific actions that would be taken and their possible effects, this analysis
assumes no changes in the Operating Partnership's financial structure.

capital and cash flows for each of the three years in the period ended December
31, 1998. 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, 1998 and 1997, and the
consolidated results of its operations and its cash flows for each of the three
years in the period ended December 31, 1998, 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.

                       ERP OPERATING LIMITED PARTNERSHIP
                  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 and is the 
general partner of the Operating Partnership. 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"), Evans Withycombe Residential, Inc.
("EWR") (the"EWR Merger") and Merry Land & Investment Company, Inc ("MRY") (the
"MRY Merger") (see Note 3).

     The Company, through the Operating Partnership, is engaged in the
acquisition, disposition, ownership, management and operation of multifamily
properties. As of December 31, 1998, the Operating Partnership controlled a
portfolio of 654 multifamily properties (individually a "Property" and
collectively the "Properties") containing 187,002 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 an investment in six
joint ventures consisting of six 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.

     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 that own certain Properties and one that has an
investment in partnership interests and subordinated mortgages collateralized by
21 of the Additional Properties (collectively, the "LLC's"). The Operating
Partnership is a 99% managing member of each LLC and a QRS Corporation is a 1%
member of each LLC.
 
     As of December 31, 1998, 700 Properties were managed by either Equity
Residential Properties Management Limited Partnership, the successor to the
multifamily residential management services (the "Management Business")
contributed by Equity Properties Management Corp. ("EPMC") contemporaneously
with the Company's initial public offering (the "EQR IPO"), or 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, the EWR Merger and the MRY 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
assets acquired and the liabilities assumed of MRY were recorded at their
relative fair values as of October 19, 1998 (the "MRY Closing Date"). The
accompanying consolidated statements of operations and cash flows include the
results of the Properties purchased through the Mergers 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
Partnerships, the LLCs and Merry Land DownREIT I LP, each such entity has been
consolidated with the Operating Partnership for financial reporting purposes. In
regard to Management Corp., Management Corp. II, Evans Withycombe Management,
Inc. and ML Services, 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.

4.   Partners' Capital

     The limited partners of the Operating Partnership as of December 31, 1998
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 13,187,929 OP Units which are exchangeable,
subject to certain restrictions, on a one-for-one basis into the Company's
Common Shares (which amount includes units held by minority interest owners in
Merry Land DownREIT I LP, which were converted to 180,585 OP Units subsequent to
December 31, 1998). In addition, on December 22, 1998, in conjunction with the
acquisition of Scarborough Square, the Operating Partnership issued 46,328
Junior Convertible Preference Units, which are convertible into 98,626 OP Units.
As of December 31, 1998, the Company (as the general partner) had an approximate
89.90% interest and the Limited Partners had an approximate 10.10% 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
Partners' 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
or Junior Convertible Preference Units) to account for the change in their
respective percentage ownership of the equity of the Operating Partnership.

    The Operating Partnership paid a $0.67, $0.67, $0.67 and $0.71 per OP Unit
distribution on April 10, July 10, October 9 and December 31, 1998,
respectively, for the quarters ended March 31, June 30, September 30 and
December 31, 1998, to OP Unit holders of record on March 27, June 26, September
16 and December 20, 1998, respectively.

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.

     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 Properties under development and/or
expansion and lease-up properties as construction-in-progress until construction
on the apartment community has been completed and all certificates of occupancy
permits have been obtained. The Operating Partnership also classifies land
relating to construction-in-progress as land on its balance sheet. Land
associated with construction-in-progress was $19.4 million and $8.3 million as
of December 31, 1998 and 1997, respectively.

  (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.

  (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. The accumulated amortization of such
deferred financing costs was $8.2

                                      F-13

million and $4.2 million at December 31, 1998 and 1997, 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)  Derivative Instruments and Hedging Activities

     In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 133, Accounting for Derivative
Instruments and Hedging Activities ("Statement No. 133"). Statement No. 133
requires recording all derivative instruments as assets or liabilities measured
at fair value. Derivatives that are not hedges must be adjusted to fair value
through income. If the derivative is a hedge, depending on the nature of the
hedge, changes in the fair value of derivatives will either be offset against
the change in fair value of the hedged assets, liabilities, or firm commitments
through earnings or recognized in other comprehensive income until the hedged
item is recognized in earnings. The ineffective portion of a derivative's change
in fair value will be immediately recognized in earnings. Statement No. 133 is
effective for fiscal years beginning after June 15, 1999. The Operating
Partnership is planning to adopt Statement No. 133 effective January 1, 2000 and
does not anticipate that the adoption will have a material impact on the
Operating Partnership's financial condition and results of operations.

  (f)  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, 1998 and 1997
was estimated to be approximately $91.8 million and $184.8 million,
respectively, compared to the Operating Partnership's carrying value of $88
million and $176.1 million, respectively. 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.

  (g)  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.

                                  (Continued)

  (h)  Lease Agreements

     The majority of the leases entered into between a tenant and a Property for
the rental of an apartment unit are year-to-year, renewable upon consent of both
parties on a year-to-year or month-to-month basis.
 
  (i)  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 or
franchise taxes. The aggregate cost of land and depreciable property for Federal
income tax purposes as of December 31, 1998 and 1997 was approximately $9.1
billion and $6.2 billion, respectively.

  (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.

  (l)  Reportable Segments

     During the fourth quarter of 1998, the Operating Partnership adopted
Statement of Financial Accounting Standards No. 131, Disclosures about Segments
of an Enterprise and Related Information ("Statement No. 131"). Statement No.
131 superseded FASB Statement of Financial Accounting Standards No. 14,
Financial Reporting for Segments of a Business Enterprise ("Statement No. 14").
Statement No. 131 establishes standards for the way that public business
enterprises report information regarding reportable operating segments. The
adoption of Statement No. 131 did not affect the Operating Partnership's results
of operations or financial position.

     The Operating Partnership has one primary reportable business segment,
which consists of investment in rental real estate. The Operating Partnership's
primary business is owning, managing and operating multifamily residential
properties which includes the generation of rental and other related income
through the leasing of apartment units to tenants. The Operating Partnership
also has a segment for corporate level activity including such items as interest
income earned on short-term investments, interest income earned on investment in
mortgage notes, general and administrative expenses, and interest expense on
mortgage notes payable and unsecured note issuances. In addition, the Operating
Partnership has a segment for third party management activity that is immaterial
and does not meet the threshold requirements of Statement No. 131 as a
reportable segment.

                       ERP OPERATING LIMITED PARTNERSHIP
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (Continued)

     The Operating Partnership evaluates performance and allocates resources
primarily based on the rental and other income generated from each property less
property and maintenance expenses, real estate taxes and insurance, and property
management expenses, which is considered net operating income ("NOI").  However,
all other segment measurements are disclosed in the Operating Partnership's
consolidated financial statements, and accordingly the accounting policies of
the reportable segments are the same as those described elsewhere in the Summary
of Significant Accounting Policies.

     The Operating Partnership also considers funds from operations ("FFO") to
be a primary measure of the performance of real estate companies. 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 generally
accepted accounting principles ("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 and 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 real estate
companies and, accordingly, may not be comparable to such other companies.

     All revenues are from external customers and no revenues are generated from
transactions with other segments.  There are no tenants who contributed 10% or
more of the Operating Partnership's total revenues during 1998, 1997 or 1996.
Interest expense on debt is not allocated to individual Properties, even if the
Properties secure such debt.  There is no provision for income taxes as 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.

(1) Convertible Preference Units that could be converted into 8,739,688 and 
    2,763,898 weighted shares of Common Shares (which would be contributed to
    the Operating Partnership in exchange for OP Units) were outstanding at
    December 31, 1998 and 1997, respectively, but were not included in the
    computation of diluted earnings per OP Unit because the effects would be
    anti-dilutive.

(2) Pursuant to the Company's share option plan, the Company has offered the 
    opportunity to acquire Common Shares through the grant of share options
    ("Options") to officers, directors, key employees and consultants of the
    Company for 6.2 million, 4.1 million and 2.3 million Common Shares at a
    weighted average exercise price of $40.60, $36.22 and $28.76 per Common
    Share as of December 31, 1998, 1997 and 1996, respectively. As of December
    31, 1998, 1997 and 1996, 2.9 million, 1.3 million and 0.9 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
    dilutive effect of the Company's Options have been included in the number of
    OP Units outstanding - assuming dilution.

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 amount), $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, 1998 and 1997, the second mortgage notes had a combined
principal balance of approximately $21.7 million and $25.5 million,
respectively, 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.  As of December 31, 1998 and 1997, the third mortgage notes had a
combined principal balance of approximately $71.1 million and $71.1 million,
respectively, 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 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, 1998 and 1997
was $6 million and $9 million, respectively. During 1998, 1997 and 1996, the
Operating Partnership amortized $3 million, $3.1 million and $0.6 million,
respectively, which is included in interest income-investment in mortgage notes
in the consolidated statements of operations.  This discount is being amortized
utilizing the effective yield method based on the expected life of the
investment.

     On April 28, 1997, the Operating Partnership made an $88 million investment
in six mortgage loans collateralized by five multifamily properties.  On April
1, 1998, the Operating Partnership purchased these five multifamily Properties
and no longer has an investment in the mortgage loans, but has assumed $50
million in debt in connection with this acquisition.  These five Properties are
no longer included in the Additional Properties, but are now included in the
Properties.

11.  Mortgage Notes Payable

     As of December 31, 1998, the Operating Partnership had outstanding mortgage
indebtedness of approximately $2.3 billion encumbering 216 of the Properties.
The carrying value of such Properties (net of accumulated depreciation of $250
million) was approximately $3.8 billion.  The mortgage notes payables are
generally due in monthly installments of principal and interest.  In connection
with the Properties acquired during the year ended December 31, 1998, including
the effects of the MRY Merger, the Operating Partnership assumed the outstanding
mortgage balances on 58 Properties in the aggregate amount of $608.9 million,
which includes a premium of approximately $1.5 million recorded in connection
with the MRY Merger.

     As of December 31, 1998, scheduled maturities for the Operating
Partnership's outstanding mortgage indebtedness are at various dates through
October 1, 2033.  During the year ended December 31, 1998, the effective
interest cost calculated for all the Operating Partnership's debt was 7.10%.
During the year ended December 31, 1998, the Operating Partnership repaid the
outstanding mortgage balances on nine Properties in the aggregate amount of
$63.8 million.

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

     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 principal and interest.  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.

     During the year ended December 31, 1997, the effective interest cost
calculated for all the Operating Partnership's debt was 7.5%.  During the year
ended December 31, 1997, the Operating Partnership repaid the outstanding
mortgage balances on eight Properties in the aggregate amount of $113.4 million.

     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 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.  No such financial
instrument has been used for trading purposes.

     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.

     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, 1998 and
1997, the aggregate notional amounts of these agreements were approximately
$172.1 million and $174.3 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, 1998 and 1997,
the aggregate notional amount of these agreements was approximately $172.1
million and $174.3 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 also has an interest rate cap agreement for a
notional amount of $228 million, 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.

     In May 1998, the Operating Partnership entered into an interest rate
protection agreement to effectively fix the interest rate of the Evans
Withycombe Financing Limited Partnership indebtedness to within a range of 5.6%
to 6.0% upon its refinancing. The agreement was for a notional amount of $131
million with a settlement date of August 2001. There was no initial cost to the
Operating Partnership for entering into this agreement.

     In August 1998, the Operating Partnership entered into an interest rate
protection agreement to effectively fix the interest rate cost of the Operating
Partnership's planned financing in the fourth quarter of 1998.  This agreement
was cancelled in November at a cost of approximately $3.7 million.  This cost is
being amortized over the life of the financing for the fifteen previously
unencumbered Properties that occurred in November 1998.

     In August 1998, the Operating Partnership entered into an interest rate
swap agreement that fixed the Operating Partnership's interest rate risk on a
portion of the Operating Partnership's variable rate tax-exempt bond
indebtedness at a rate of 3.65125%.  This agreement was for a notional amount of
$150 million with a termination date of August 2003.

     In August 1998, the Operating Partnership entered into an interest rate
swap agreement that fixed the Operating Partnership's interest rate risk on a
portion of the Operating Partnership's variable rate tax-exempt bond
indebtedness at a rate of 3.683%.  This agreement was for a notional amount of
$150 million with a termination date of August 2005.

     The Operating Partnership believes that it has limited exposure to the
extent of non-performance by the counterparties of the agreements since each

     Douglas Crocker II, President and Chief Executive Officer of the Company,
and three other officers had purchased an aggregate of 190,000 Common Shares at
prices which range from $26 to $31.625 per Common Share. These purchases were
financed by loans made by the Operating Partnership in the aggregate amount of
approximately $5.3 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 three other officers and are collateralized by
pledges of the 190,000 Common Shares purchased.

     In addition, as of December 31, 1998, the outstanding principal balance on
additional notes issued to Mr. Crocker and four other officers was approximately
$1.1 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.  Subsequent to December 31, 1998, Mr. Crocker paid a principal
installment on his note in the amount of $80,570.  The notes are recourse to Mr.
Crocker and the four other officers and are collateralized by pledges of options
and share awards.

Compensation Agreement") which Deferred Compensation Agreement will provide Mr.
Crocker with a salary benefit after his termination of employment with the
Company. If Mr. Crocker's employment is terminated without cause, he would be
entitled to annual deferred compensation for a ten-year period commencing on the

year beginning January 1, 1997), 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%
and the maximum paid per year would not exceed 100% of his average base salary.

Should Mr. Crocker be terminated for cause or should he choose to leave
voluntarily without good reason, he would not be entitled to any deferred
compensation. The Operating Partnership recognized approximately $0.3 million,
$0.3 million and $0.3 million of compensation expense for the years ended 1998,
1997 and 1996, respectively, 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
without cause, 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 without
good reason, he would not be entitled to any deferred compensation. The
Operating Partnership has recognized approximately $0.2 million and $0.2 million
of compensation expense for the years ended 1998 and 1997, respectively, 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 three-year period and are
effective for ten 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 dividends that would
have been paid on these shares being exercised had he owned these
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 the Share Distributions Agreement. The Operating Partnership
recognized approximately $0.3 million, $0.2 million and $0.2 million of
compensation expense for the years ended 1998, 1997 and 1996, respectively,
related to this Share Distributions Agreement.

     The Company has established a defined contribution plan (the "401(k) Plan")
that provides retirement benefits for employees that meet minimum employment
criteria. The Operating Partnership contributes 100% of the first 4% of eligible
compensation that a participant contributes to the 401(k) Plan. Participants are
vested in the Company's contributions over five years. The Operating
Partnership, on behalf of the Company, made contributions in the amount of $0.8
million and $1.4 million for the years ended December 31, 1996 and 1997,
respectively, and expects to make contributions in the amount of approximately

quarterly at a price equal to 85% of the lessor of: (a) the closing price for a
share on the first day of such quarter, and (b) the greater of: (i) the closing
price for a share on the first day of such quarter, and (ii) the average closing

32.  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 litigation
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 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. During 1997 and 1998, the Operating Partnership
funded a total of $6.9 million and $23.9 million, respectively, and during 1999
the Operating Partnership expects to fund approximately $74.9 million in
connection with this agreement. Subsequent to December 31, 1998, the Operating
Partnership has funded approximately $1 million. In addition, the Operating
Partnership also funded $20 million to guarantee third party construction
financing and is obligated to fund up to an additional $20 million.

     In regards to certain properties that were under development and/or
expansion in 1998, the Operating Partnership funded $31.6 million. In 1999, the
Operating Partnership expects to fund $53.9 million related to the continued
development and/or expansion of as many as five Properties.

     In regards to certain properties that were under earnout/development
agreements in 1998, no amounts were funded. The Operating Partnership expects to
fund $60.4 million related to three earnout/development projects expected to be
finished during 1999. Subsequent to December 31, 1998, the Operating Partnership
has funded $16.2 million relating to the completion/acquisition of Copper
Canyon. In addition, the Operating Partnership may be required to fund an
additional $1 million earnout payment to the developer for Copper Canyon if
certain specified operation levels are met.

     In connection with the Wellsford Merger, the Operating Partnership has
provided a $14.8 million credit enhancement with respect to bonds issued to
finance certain public improvements at a multifamily development project.
Pursuant to the terms of a Stock Purchase Agreement with Wellsford Real
Properties, Inc. ("WRP Newco"), the Operating Partnership will agree to purchase
up to 1,000,000 shares of WRP Newco Series A Preferred at $25.00 per share over
a three-year period ending on May 30, 2000. As of December 31, 1998, no shares
of WRP Newco Series A Preferred had been acquired by the Operating Partnership.

     In connection with the MRY Merger, the Operating Partnership extended a $25
million, one year, non-revolving Senior Debt Agreement to MRYP Spinco. At
December 31, 1998, approximately $18.3 million was outstanding, bearing interest
at LIBOR plus 250 basis points. The Operating Partnership has a potential
obligation to fund up to an additional $6.7 million under the Senior Debt
Agreement.
