ITEM 1.  BUSINESS

GENERAL

     ERP Operating Limited Partnership, an Illinois limited partnership
formed in May 1993 (the "Operating Partnership"), is managed and controlled
by Equity Residential Properties Trust ("EQR"), a Maryland real estate
investment trust, its general partner. EQR 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 EQR. 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"), Merry Land & Investment Company, Inc. ("MRY")
(the "MRY Merger") and Lexford Residential Trust ("LFT") ("the LFT Merger")
(collectively, the "Mergers").

     The Operating Partnership has formed a series of partnerships (the
"Financing Partnerships") which beneficially own certain Properties (see
definition below) that may be encumbered by mortgage indebtedness. In general,
these are structured so that the Operating Partnership, owns a 1% limited
partner interest and a 98% general partner interest in each, with the remaining
1% general partner interest in each Financing Partnership owned by various
qualified REIT subsidiaries wholly owned by EQR (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 Operating Partnership has also formed a series of limited liability
companies that own certain Properties (collectively, the "LLCs"). The Operating
Partnership is a 99% managing member of each LLC and a QRS Corporation is a 1%
member of each LLC.

     The Operating Partnership's subsidiaries include a series of management
limited partnerships and companies (collectively, the "Management Partnerships"
or the "Management Companies"), the Financing Partnerships, the LLCs and certain
other entities.

     As of December 31, 1999, the Operating Partnership owned or had interests
in 1,062 multifamily properties containing 225,708 units, of which it
wholly-owned a portfolio of 983 multifamily properties (individually, a
"Property" and collectively, the "Properties") containing 214,060 units. The
remaining 79 properties represent investments in partnership interests and/or
subordinated mortgages containing 11,648 units. The Operating Partnership's
Properties are located in 35 states throughout the United States. EQR is,
together with the Operating Partnership, one of the largest publicly traded
REITs (based on the aggregate market value of EQR's outstanding Common Shares)
and is 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, 1999, the Operating Partnership
has acquired direct interests in 988 properties containing 209,975 units in the
aggregate for a total purchase price of approximately $12 billion, including the
assumption of approximately $3.2 billion of mortgage indebtedness and $848.2
million of unsecured notes. Since the EQR IPO and through December 31, 1999, the
Operating Partnership has disposed of 74 properties, containing 17,640 units for
a total sales price of approximately $654.2 million.


                                       4

     The Company's corporate headquarters and executive offices are located in
Chicago, Illinois. In addition, the Operating Partnership has 31 management
offices in the following cities:

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

     The Operating Partnership has approximately 6,700 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:

     -    the value of the Properties;

     -    distributions on a per limited partnership interest ("OP Unit")
          basis;and

     -    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;
     -    maintaining a ratio of consolidated debt-to-total market
          capitalization of less than 50%
     -    strategically acquiring and disposing of properties; and
     -    purchasing newly developed, as well as co-investing in the development
          of, multifamily communities.

<PAGE>

                                     PART I

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

ACQUISITION STRATEGIES

     The Operating Partnership anticipates that future property acquisitions
will be located in the continental United States. Management will continue to
use market information to evaluate acquisition opportunities. The Operating
Partnership's market database 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 retained cash flow,
issuance of additional equity securities by EQR 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;



                                       6


<PAGE>

     -    uniqueness of location;
     -    household growth and net migration of the relevant market's
          population;
     -    supply/demand ratio, competitive housing alternatives, sub-market
          occupancy and rent levels;
     -    barriers to entry that would limit competition; and
     -    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 primarily to fund property acquisitions as well as fund development
activities. 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 subsidiaries.

EQUITY OFFERINGS FOR THE YEARS ENDED DECEMBER 31, 1997, 1998 AND 1999

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

     In March 1997, EQR completed three separate public offerings relating to an
aggregate of 1,921,000 publicly registered Common Shares, which were sold to the
public at a price of $46 per share. EQR contributed to the Operating Partnership
net proceeds of approximately $88.3 million in exchange for OP Units.

     In May 1997, EQR sold 7,000,000 depositary shares (the "Series D Depositary
Shares"). Each Series D Depositary Share represents a 1/10 fractional interest
in a 8.60% Series D Cumulative Redeemable Preferred Share of Beneficial
Interest, $0.01 par value per share (the "Series D Preferred Shares"). The
liquidation preference of each of the Series D Preferred shares is $250.00
(equivalent to $25 per Series D Depositary Share). EQR raised gross proceeds of
approximately $175 million from this offering (the "Series D Preferred Share
Offering"). The net proceeds of approximately $169.5 million from the Series D
Preferred Share Offering were contributed by EQR to the Operating Partnership in
exchange for 700,000 of the Operating Partnership's 8.60% cumulative redeemable
preference units (the "Series D Cumulative Redeemable Preference Units").

     In June 1997, EQR completed five separate public offerings comprising an
aggregate of 8,992,023 publicly registered Common Shares, which were sold to the
public at prices ranging from $44.06 to $45.88



                                       7

per share. EQR contributed to the Operating Partnership net proceeds of
approximately $398.9 million therewith in exchange for additional OP Units.

     In September 1997, EQR completed the sale of 498,000 publicly registered
Common Shares, which were sold to the public at a price of $51.125 per share.
EQR contributed to the Operating Partnership net proceeds of approximately $24.2
million in connection with this offering in exchange for OP Units.

     In September 1997, EQR sold 11,000,000 depositary shares (the "Series G
Depositary Shares"). Each Series G Depositary Share represents a 1/10 fractional
interest in a 7 1/4% Series G Convertible Cumulative Preferred Share of
Beneficial Interest, $0.01 par value per share (the "Series G Preferred
Shares"). Series G Depositary Shares representing Series G Preferred Shares are
convertible at the option of the holder thereof at any time into Common Shares
at a conversion price of $58.58 per Common Share (equivalent to a conversion
rate of approximately .4268 Common Shares for each Series G Depositary Share).
The liquidation preference of each of the Series G Preferred Shares is $250.00
per share (equivalent to $25 per Series G Depositary Share). In addition, in
October 1997, EQR sold 1,650,000 additional Series G Depositary Shares pursuant
to an over-allotment option granted to the underwriters. EQR contributed to the
Operating Partnership the net proceeds of approximately $303.6 million in
connection with this offering (the "Series G Preferred Share Offering") in
exchange for 1,265,000 of the Operating Partnership's 7 1/4% convertible
cumulative preference units (the "Series G Convertible Cumulative Preference
Units").

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

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

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

     Also in December 1997, EQR completed the sale of 467,722 publicly
registered Common Shares, which were sold at a price of $51.3125 per share. EQR
contributed to the Operating Partnership net proceeds of approximately $22.8

     During 1998, EQR issued 93,521 Common Shares pursuant to the Employee Share
Purchase Plan. EQR contributed to the Operating Partnership net proceeds of
approximately $3.7 million in exchange for OP Units.

     On February 3, 1998, EQR filed with the SEC a Form S-3 Registration
Statement to register $1 billion of equity securities. The SEC declared this
registration statement effective on February 27, 1998. In addition, EQR carried
over $272 million related to the registration statement effective on August 4,
1997. As of December 31, 1999, $1.1 billion remained outstanding under this
registration statement.

     On February 18, 1998, EQR completed two offerings of 988,340 publicly
registered Common Shares, which were sold to the public at a price of $50.625
per share. On February 23, 1998, EQR completed an offering of 1,000,000 publicly
registered Common Shares, which were sold to the public at a price of $48 per
share. EQR contributed to the Operating Partnership net proceeds from these

CREDIT FACILITY

     On August 12, 1999 the Operating Partnership obtained a new three year $700
million unsecured revolving credit facility, with Bank of America Securities LLC
and Chase Securities Inc. acting as joint lead arrangers. The new line of credit
replaced the Operating Partnership's $500 million unsecured revolving credit
facility, as well as the $120 million unsecured revolving credit facility which
the Operating Partnership assumed in the MRY Merger. The prior existing
revolving credit facilities were repaid in full



                                       11
<PAGE>

and terminated upon the closing of the new facility. This new credit facility
matures in August 2002 and will be used to fund property acquisitions, costs for
certain Properties under development and short term liquidity requirements.
Advances under the credit facility bear interest at variable rates based upon
LIBOR available at various interest periods, plus a certain spread dependent
upon the Operating Partnership's credit rating. As of March 20, 2000, there were

RECENT TRANSACTIONS

     On January 14, 2000, the Company entered into an agreement to acquire, in
an all cash and debt transaction, Globe Business Resources, Inc. ("Globe"), one
of the nation's largest providers of temporary corporate housing and furniture
rental. The shareholders of Globe will receive $13.00 per share upon closing and
up to an additional $0.50 per share post closing, upon final determination of
costs, if any, relating to any potential breaches of certain representations and
covenants. At full funding of $13.50 per share, the Company would pay
approximately $64.8 million in cash for Globe. In addition, the Operating
Partnership will assume approximately $69.4 million in debt. The acquisition,
which is expected to close during the second quarter of 2000, requires Globe
shareholder approval.

     From January 1, 2000 through March 3, 2000, the Operating Partnership
acquired Windmont Apartments, a 178-unit property located in Atlanta, GA from an
unaffiliated party for a total purchase price of approximately $10.3 million.

     From January 1, 2000 through March 3, 2000, the Operating Partnership
disposed of six Properties for a total sales price of $46.7 million.

     On March 3, 2000, Lexford Properties, L.P., a subsidiary of
the Operating Partnership, issued 1.1 million units of 8.50% Series B Cumulative
Convertible Redeemable Preference Units with an equity value of $55.0 million.
Lexford Properties, L.P. received $53.6 million in net proceeds from this
transaction. The liquidation value of these units is $50 per unit. The 1.1
million units are exchangeable into 1.1 million shares of 8.50% Series M-1
Cumulative Redeemable Preferred Shares of Beneficial Interest of EQR. The Series
M-1 Preferred Shares are not convertible to EQR Common Shares. Dividends for the
Series B Preference Units or the Series M-1 Preferred Shares are payable
quarterly at the rate of $4.25 per unit/share per year. The net proceeds
received from this transaction will be used for scheduled mortgage and line of
credit repayments.

<PAGE>

     On March 20, 2000, the Operating Partnership obtained new mortgage
financing on eleven previously unencumbered properties in the amount of $148.3
million. The net proceeds received from this transaction will be used for
scheduled mortgage and line of credit repayments.

COMPETITION

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

RISK FACTORS

     THE FOLLOWING RISK FACTORS OMIT THE USE OF DEFINED TERMS USED ELSEWHERE
HEREIN AND CONTAIN DEFINED TERMS THAT ARE DIFFERENT FROM THOSE USED IN THE OTHER
SECTIONS OF THIS REPORT. UNLESS OTHERWISE INDICATED, WHEN USED IN THIS SECTION,
THE TERMS "WE" AND "US" REFER TO ERP OPERATING LIMITED PARTNERSHIP, AN ILLINOIS
LIMITED PARTNERSHIP, WHICH IS MANAGED BY ITS GENERAL PARTNER EQUITY RESIDENTIAL
PROPERTIES TRUST, A MARYLAND REAL ESTATE INVESTMENT TRUST.

     Set forth below are the risks that we believe are important to investors
who purchase or own our Units of limited partnership interest or debt
securities. In this section, we refer to the Units and debt 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, 1999, certain of our multifamily properties were subject
to approximately $2.9 billion of mortgage indebtedness and our total debt
equaled approximately $5.5 billion. Of our total debt outstanding, $700.9
million (including the balance of $300 million outstanding on our $700 million
unsecured line of credit) was floating rate debt and $965.8 million was 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.



                                       15


<PAGE>

     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 could adversely affect our cash
flow and could 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 that,
among other things, limit our ability, without the prior consent of the lender,
to further mortgage the property 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,
maintenance of 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. If we are unable to
acquire additional properties, our ability to increase the distributions to
security holders, as we have done in the past, will be limited to management's
ability to increase funds from operations, and thereby cash available for
distributions, from the existing properties in our portfolio at such time.

         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 42.75% as of December 31, 1999. We have a
policy of incurring indebtedness for borrowed money only if upon such incurrence
our 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 facility bear interest at variable rates based
upon LIBOR available at various interest periods, 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 would


                                       16

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.

     Substantially all of our properties have been the subject of environmental
assessments completed by qualified independent environmental consultant
companies. These 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.

<PAGE>

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 that 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.

     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 Chairman of the Board of Trustees of our
general partner, Samuel Zell, and the executive officers of our general partner,
particularly Douglas Crocker II and Gerald A. Spector. If they resign, our
operations could be temporarily adversely effected. Mr. Crocker and Mr. Spector
have entered into Deferred Compensation Agreements with our general partner,
which provide both with a salary benefit after their respective termination of
employment with our general partner. In addition, Mr. Zell, Mr. Crocker and Mr.
Spector have entered into Noncompetition Agreements 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, we
may not be able to fund all future capital needs, including for acquisitions and
developments, from income generated by operations and the disposition of certain
assets. We therefore may 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 increase our leverage.

ITEM 2.  THE PROPERTIES

     As of December 31, 1999, the Operating Partnership owned or had interests
in a portfolio of 1,062 multifamily Properties located in 35 states containing
225,708 apartment units. The Operating Partnership has:

     Tenant leases are generally year-to-year and require security deposits. The
garden-style properties are generally defined as properties with two and/or
three floors while the mid-rise/high-rise properties are defined as properties
greater than three floors. These two property types typically provide residents
with amenities, which may include a clubhouse, swimming pool, laundry facilities
and cable television access. Certain of these properties offer additional
amenities such as saunas, whirlpools, spas, sports courts and exercise rooms.
The ranch-style properties, which are defined as single story properties,
generally do not provide additional amenities for its residents.

     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



                                       19

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 976 of the
983 controlled Properties and holds a 99-year leasehold interest with respect to
one Property (Mallgate). 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 the debt
collateralized by the Properties. The remaining 79 properties represent
investments in partnership interests and/or subordinated mortgages containing
11,648 units.

     Direct fee simple title for certain of the Properties is owned by
single-purpose nominee corporations, LLC's 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 a single LLC.

     The Operating Partnership also leases (under operating leases) various
management, regional and corporate offices throughout the United States. See
Item 1 for the locations of these offices.

     The following table sets forth certain information by type and by state
relating to the Properties owned by the Operating Partnership or in which the
Operating Partnership had a direct equity or mortgage interest as of December
31, 1999.

ITEM 6.  SELECTED FINANCIAL DATA (CONSOLIDATED HISTORICAL (CONTINUED))

(1)  Includes approximately $18.0 million and $96.3 million of construction in
     progress as of December 31, 1999 and 1998, respectively.

(2)  Totals exclude properties which the Operating Partnership had investments
     in partnership interests and/or subordinated mortgages. As of December 31,
     1999, this represented 79 properties containing 11,648 units. As of
     December 31, 1998, this represented 27 properties containing 5,193 units.
     As of December 31, 1997, this represented 26 properties containing 5,267
     units.

(3)  The Operating Partnership generally considers funds from operations ("FFO")
     to be one measure of the performance of real estate companies, including an
     equity REIT. The 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 Company 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 has
     been restated to reflect the effects of the definition as mentioned above.
     The Operating Partnership will adopt, effective January 1, 2000, NAREIT's
     updated recommended definition of FFO as approved in the fourth quarter of
     1999.

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

RESULTS OF OPERATIONS (CONTINUED)

     The Operating Partnership's overall results of operations for the year
ended December 31, 1999 and 1998 have been significantly impacted by the
Operating Partnership's acquisition and disposition 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 1998 Acquired
Properties and the 1999 Acquired Properties, partially offset by the disposition
of the 1998 Disposed Properties and the 1999 Disposed Properties. The impact of
the 1998 Acquired Properties, the 1999 Acquired Properties, the 1998 Disposed
Properties and the 1999 Disposed Properties is discussed in greater detail in
the following paragraphs.

     Properties that the Operating Partnership owned for all of both 1999 and
1998 (the "1999 Same Store Properties"), which represented 121,490 units,
impacted the Operating Partnership's results of operations. Properties that the
Operating Partnership owned for all of both 1998 and 1997 (the "1998 Same Store
Properties"), which represented 63,243 units, also impacted the Operating
Partnership's results of operations. Both the 1999 Same Store Properties and
1998 Same Store Properties are discussed in the following paragraphs.

     COMPARISON OF THE YEAR ENDED DECEMBER 31, 1999 TO THE YEAR ENDED DECEMBER
     31, 1998

     For the year ended December 31, 1999, income before gain on disposition of
properties, net, and extraordinary item increased by $75.3 million when compared
to the year ended December 31, 1998. This increase was primarily due to the
acquisition of the 1998 Acquired Properties and the 1999 Acquired Properties as
well as 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 1999 Same Store Properties, total revenues increased by
approximately $35.8 million to $1.1 billion or 3.48% primarily as a result of
higher rental rates charged to new tenants and tenant renewals and an increase
in income from billing tenants for their share of utility costs as well as other
ancillary services provided to tenants. Overall, property operating expenses,
which include property and maintenance, real estate taxes and insurance and an
allocation of property management expenses, increased approximately $0.1 million
or 0.03%. This increase was primarily the result of higher expenses for on-site
compensation costs and an increase in real estate taxes on certain properties,
but was partially offset by lower leasing and advertising, administrative,
maintenance and property management costs.

     Property management represents expenses associated with the self-management
of the Operating Partnership's Properties. These expenses increased by
approximately $8.5 million primarily due to the continued expansion of the
Operating Partnership's property management business. During 1999, the Operating
Partnership assumed a management office in Reynoldsburg, Ohio related to the LFT
Merger.

     Fee and asset management revenues and fee and asset management expenses are
associated with the management of properties not owned by the Operating
Partnership that are managed for affiliates. These revenues and expenses
decreased due to the Operating Partnership acquiring certain of these properties
that were formerly fee-managed.

     Interest expense, including amortization of deferred financing costs,
increased by approximately $91.9 million. This increase was primarily the result
of an increase in the Operating Partnership's average indebtedness outstanding
which increased by $1.3 billion. However, the Operating Partnership's effective


                                       29

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF

RESULTS OF OPERATIONS (CONTINUED)

interest costs decreased from 7.10% for the year ended December 31, 1998 to
7.05% for the year ended December 31, 1999.

     General and administrative expenses, which include corporate operating
expenses, increased approximately $1.7 million between the periods under
comparison. This increase was primarily due to the addition of corporate
personnel. However, by gaining certain economies of scale with a much larger
operation these expenses as a percentage of total revenues were 1.27% for the
year ended December 31, 1999 compared to 1.54% of total revenues for the year
ended December 31, 1998.

     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, net 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 1998 Same Store Properties 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.

     Property management represents expenses associated with the self-management
of the Operating Partnership's Properties. These expenses increased by
approximately $26.3 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 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 $5.8 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 1.54% for the year ended December 31, 1998 compared to
1.98% of total revenues for the year ended December 31, 1997.

LIQUIDITY AND CAPITAL RESOURCES

FOR THE YEAR ENDED DECEMBER 31, 1999

     As of January 1, 1999, the Operating Partnership had approximately $4
million of cash and cash equivalents and $330 million available on its lines of
credit, of which $12 million was restricted. After taking into effect the
various transactions discussed in the following paragraphs, the Operating
Partnership's cash and cash equivalents balance at December 31, 1999 was
approximately $29.1 million and the amount available on the Operating
Partnership's line of credit was $400 million, of which $65.8 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 (used for) financing activities, all of which are presented in
the Operating Partnership's 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 two joint ventures with
multifamily real estate developers 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
1999, EQR and/or the Operating Partnership:

     -    issued the June 2004 Notes and received net proceeds of $298.0
          million;
     -    refinanced seven Properties and received additional proceeds of $78.5
          million;
     -    obtained new mortgage financing on eleven previously unencumbered
          properties and received net proceeds of $126.5 million;
     -    disposed of forty-two properties (including the sale of the Operating
          Partnership's interest in six MRY joint venture properties) and
          received net proceeds of $383 million;
     -    issued approximately 1.2 million Common Shares and received net
          proceeds of $38.5 million which were contributed by EQR to the
          Operating Partnership in exchange for OP Units; and
     -    issued 800,000 8.00% Series A Cumulative Convertible Redeemable
          Preference Interests of EQR-Mosaic, L.L.C. and received net proceeds
          of $39 million.

All of these proceeds were utilized to either:

     -    purchase additional properties;
     -    provide funding for properties in the development stage; and/or
     -    repay the line of credit and mortgage indebtedness on certain
          Properties

     With respect to the 1999 Acquired Properties, the Operating Partnership
assumed and/or entered into new mortgage indebtedness of approximately $69.9
million, issued OP Units with a value of $25.2 million and issued Junior
Convertible Preference Units with a value of $3.0 million. The total purchase
price of the 1999 Acquired Properties was approximately $1.4 billion.

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

LIQUIDITY AND CAPITAL RESOURCES (CONTINUED)

     Subsequent to December 31, 1999 and through March 3, 2000, the Operating
Partnership acquired one additional property containing 178 units for a total
purchase price of approximately $10.3 million.

     Subsequent to December 31, 1999 and through March 3, 2000, the Operating
Partnership disposed of six properties for a total sales price of $46.7 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.

     On March 3, 2000, Lexford Properties, L.P., a subsidiary of
the Operating Partnership, issued 1.1 million units of 8.50% Series B Cumulative
Convertible Redeemable Preference Units with an equity value of $55.0 million.
Lexford Properties, L.P. received $53.6 million in net proceeds from this
transaction. The liquidation value of these units is $50 per unit. The 1.1
million units are exchangeable into 1.1 million shares of 8.50% Series M-1
Cumulative Redeemable Preferred Shares of Beneficial Interest of EQR. The Series
M-1 Preferred Shares are not convertible to EQR Common Shares. Dividends for the
Series B Preference Units or the Series M-1 Preferred Shares are payable
quarterly at the rate of $4.25 per unit/share per year. The net proceeds
received from this transaction will be used for scheduled mortgage and line of
credit repayments.

     In regard to the joint venture agreements with two multifamily residential
real estate developers during the year ended December 31, 1999, the Operating
Partnership funded a total of $88.6 million and during 2000 the Operating
Partnership expects to fund approximately $32.7 million in connection with these
agreements. In connection with the first agreement, the Operating Partnership
has an obligation to fund up to an additional $20 million to guarantee third
party construction financing.

     In regard to certain other properties that were under development and/or
expansion during the year ended December 31, 1999, the Operating Partnership
funded $47.5 million. During 2000, the Operating Partnership expects to fund
$44.9 million related to the continued development and/or expansion of as many
as three Properties.

     In regard to certain properties that were under earnout/development
agreements, during the year ended December 31, 1999, the Operating Partnership
funded the following:

     -    $17.2 million relating to the acquisition of Copper Canyon Apartments,
          which included a $1.0 million earnout payment to the developer;
     -    $24.9 million relating to the acquisition of Skyview Apartments, which
          included a $3.1 million earnout payment to the developer; and
     -    $18.3 million relating to the acquisition of Rosecliff Apartments.

     Subsequent to December 31, 1999, the Operating Partnership funded $2.3
million for an initial earnout payment to the developer of Rosecliff Apartments.
During 2000, the Operating Partnership expects to fund $33.4 million related to
the continued earnout/development of one Property.

     In May 1999, the Operating Partnership repaid its 1999 Notes that matured
on May 15, 1999. The $125 million repayment was initially funded from borrowings
under the Operating Partnership's lines of credit.

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

LIQUIDITY AND CAPITAL RESOURCES (CONTINUED)

     In November 1999, the Operating Partnership repaid the 1999-A Notes that
matured on November 24, 1999. The $25 million repayment was initially funded
from borrowings under the Operating Partnership's line of credit.

     During 1999, the Operating Partnership repaid approximately $60.8 million
of mortgage indebtedness on 31 Properties. These repayments were funded from the
Operating Partnership's line of credit and/or certain proceeds from
dispositions.

     In addition, the Operating Partnership refinanced the debt on six existing
properties totaling $45.0 million with new mortgage indebtedness totaling $65.7
million.

     As of December 31, 1999, the Operating Partnership had total indebtedness
of approximately $5.5 billion, which included mortgage indebtedness of $2.9
billion (including premiums of $2.1 million), of which $838 million represented
tax-exempt bond indebtedness, and unsecured debt of $2.3 billion (including net
discounts and premiums in the amount of $2.5 million), of which $127.8 million
represented tax-exempt bond indebtedness.

     Subsequent to December 31, 1999, the Operating Partnership settled on a
$100 million interest rate protection agreement and received approximately $7.0
million in connection therewith.

     On March 20, 2000, the Operating Partnership obtained new mortgage
financing on eleven previously unencumbered properties in the amount of $148.3
million. The net proceeds received from this transaction will be used for
scheduled mortgage and line of credit repayments.

     In the second quarter of 2000, the Operating Partnership anticipates
repaying mortgage indebtedness of approximately $85 million assumed in
connection with the LFT Merger. These repayments will also be primarily funded
from additional borrowings under the line of credit and/or additional mortgage
borrowings.

     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 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%.

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

LIQUIDITY AND CAPITAL RESOURCES (CONTINUED)

     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 1998. This agreement
was canceled 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,
1999 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.
Expenditures for in-the-unit replacement-type items such as appliances,
draperies, carpeting and floor coverings, mechanical equipment and certain
furniture and fixtures are 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, 1999, total capital expenditures for the
Operating Partnership approximated $141.9 million. Of this amount, approximately
$34.5 million, or $427 per unit, related to capital improvements and major
repairs for the 1997, 1998 and 1999 Acquired Properties. Capital improvements
and major repairs for all of the Operating Partnership's pre-EQR IPO properties
and 1993, 1994, 1995 and 1996 Acquired Properties approximated $40.8 million, or
$362 per unit. Capital spent for replacement-type items approximated $53.5
million, or $277 per unit. In addition, approximately $5.9 million was spent on
four specific assets related to major renovations and repositioning of these
assets. Also included in total capital expenditures was approximately $7.2
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 2000 are budgeted to be approximately $110.0 million
for all

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

LIQUIDITY AND CAPITAL RESOURCES (CONTINUED)

Properties.

     Total distributions paid in 1999 amounted to $514.9 million, which included
certain distributions declared in the fourth quarters of 1998 and 1999. The
Operating Partnership paid a $0.76 per OP Unit distribution on December 31, 1999
for the quarter ended December 31, 1999 to OP Unit holders of record as of
December 20, 1999.

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

     On August 12, 1999 the Operating Partnership obtained a new three year $700
million unsecured revolving credit facility, with Bank of America Securities LLC
and Chase Securities Inc. acting as joint lead arrangers. The new line of credit
replaced the Operating Partnership's $500 million unsecured revolving credit
facility, as well as the $120 million unsecured revolving credit facility which
the Operating Partnership assumed in the MRY Merger. The prior existing
revolving credit facilities were repaid in full and terminated upon the closing
of the new facility. This new credit facility matures in August 2002 and will be
used to fund property acquisitions, costs for certain properties under
development and short term liquidity requirements. Advances under the credit
facility bear interest at variable rates based upon LIBOR at various interest
periods, plus a certain spread dependent upon the Operating Partnership's credit
rating. As of March 20, 2000, there were no amounts outstanding under this new
facility.

     Pursuant to the LFT Merger, the Operating Partnership assumed a line of
credit that had an outstanding balance of approximately $26.4 million. On
October 1, 1999, the Operating Partnership repaid the outstanding balance and
terminated this facility.

     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 has agreed to purchase
up to 1,000,000 shares of WRP Newco Series A Preferred at $25.00 per share on a
standby basis over a three-year period ending on May 30, 2000. These preferred
shares would be convertible to WRP Newco common shares under certain
circumstances. As of December 31, 1999, no shares of WRP Newco Series A
Preferred had been acquired by the Operating Partnership. The Operating
Partnership expects to fund this $25 million investment in April 2000.

     In connection with the MRY Merger, the Operating Partnership extended a $25
million, one year, non-revolving loan to MRYP Spinco pursuant to a Senior Debt
Agreement. On June 24, 1999, MRYP

LIQUIDITY AND CAPITAL RESOURCES (CONTINUED)

Spinco repaid the entire outstanding Senior Note balance of $18.3 million and
there is no further obligation by either party in connection with this
agreement.

     Also, in connection with the MRY Merger, the Operating Partnership entered
into six joint venture agreements with MRYP Spinco. The Operating Partnership
contributed six properties with an initial value of $52.7 million in return for
an ownership interest in each joint venture. On August 23, 1999, the Operating
Partnership sold its entire interest in these six properties to MRYP Spinco and
received $54.1 million. There is no further obligation by either party in
connection with these agreements.

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 EQR 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 EQR 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, EQR 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 EQR to the Operating Partnership, the Operating Partnership
issued OP Units and cumulative convertible or redeemable preference units):

     -    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 1998, the Operating Partnership funded a
total of $23.9 million in connection with this agreement.

     In regards to certain other properties that were under development and/or
expansion in 1998, the Operating Partnership funded $31.6 million.

     In regards to certain properties that were under earnout/development
agreements in 1998, no amounts were funded.

     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 line of credit or
from proceeds received from the various capital transactions mentioned in the
previous paragraphs.

YEAR 2000 ISSUE

     In prior years, the Operating Partnership discussed the nature and progress
of its plans to become Year 2000 ready. In late 1999, the Operating Partnership
completed its remediation and testing of systems. As a result of those planning
and implementation efforts, the Operating Partnership experienced no significant
disruptions in mission critical information technology and non-information
technology systems and believes those systems successfully responded to the Year
2000 date change. The Operating Partnership expensed approximately $184,000 and
$700,000 during 1999 and 1998, respectively, in connection with remediating its
systems. The Operating Partnership is not aware of any material problems
resulting from Year 2000 issues, either with its products, its internal systems,
or the products and services of third parties. The Operating Partnership will
continue to monitor its mission critical computer applications and those of its
suppliers and vendors throughout the year 2000 to ensure that any latent Year
2000 matters that may arise are addressed promptly.

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

FUNDS FROM OPERATIONS

     Commencing in 1996, the Operating Partnership implemented the definition of
FFO adopted by the Board of Governors of NAREIT in March 1995. The 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 Operating Partnership's
calculation of FFO may differ from the methodology for calculating FFO utilized
by other companies and, accordingly, may not be comparable to such other
companies.

     The Operating Partnership will adopt, effective January 1, 2000, NAREIT's
updated recommended definition of FFO as approved in the fourth quarter of 1999.

     For the year ended December 31, 1999, FFO increased $160.8 million
representing a 35% increase when compared to the year ended December 31, 1998.
For the year ended December 31, 1998, FFO increased by $188.1 million
representing a 69.5% increase when compared to the year ended December 31, 1997.

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
$5.5 billion at December 31, 1999, of which approximately $700.9 million, or
12.8%, 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 55 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 $3.9
million. If market rates of interest on the Operating Partnership's floating
rate debt decrease by 55 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 $3.9 million.

         These amounts were determined by considering the impact of hypothetical
interest rates and equity prices 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.

                         REPORT OF INDEPENDENT AUDITORS

To the Partners
ERP Operating Limited Partnership

We have audited the accompanying consolidated balance sheets of ERP Operating
Limited Partnership (the "Operating Partnership") as of December 31, 1999 and
1998, and the related consolidated statements of operations, partners' capital
and cash flows for each of the three years in the period ended December 31,
1999. Our audits also included the financial statement schedule listed in the
Index at Item 14(a). These financial statements 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 auditing standards generally accepted
in the United States. 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, 1999 and 1998, and the
consolidated results of its operations and its cash flows for each of the three
years in the period ended December 31, 1999, in conformity with accounting
principles generally accepted in the United States. 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 ("REIT") 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"), Merry Land & Investment Company, Inc ("MRY") (the "MRY Merger") and
Lexford Residential Trust ("LFT") ("the LFT Merger") (see Note 4).

         The Operating Partnership is engaged in the acquisition, disposition,
ownership, management and operation of multifamily properties. As of December
31, 1999, the Operating Partnership owned or had interests in a portfolio of
1,062 multifamily properties containing 225,708 apartment units of which it
controlled a portfolio of 983 multifamily properties containing 214,060
apartment units (individually a "Property" and collectively the "Properties").
The Operating Partnership had an investment in partnership interests (equity
investments) and/or an investment in subordinated mortgages collateralized by
the remaining 79 Properties containing 11,648 units. These properties are
located in 35 states throughout the United States.

            The Operating Partnership has formed a series of partnerships (the
"Financing Partnerships") which beneficially own certain Properties that may be
encumbered by mortgage indebtedness. In general, these are structured so that
the Operating Partnership owns a 1% limited partner interest and a 98% general
partner interest in each, with the remaining 1% general partner interest in each
Financing Partnership owned by various qualified REIT subsidiaries wholly owned
by EQR (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 Operating Partnership has
also formed a series of limited liability companies that own certain 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.

2.          BASIS OF PRESENTATION

            The Wellsford Merger, the EWR Merger, the MRY Merger and the LFT
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 assets acquired and the liabilities assumed of LFT were
recorded at their relative fair values as of October 1, 1999 (the "LFT 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 a series of management limited partnerships and
companies (collectively, the "Management Partnerships" or the

                                       F-9

                                  (CONTINUED)

"Management Companies"), the Financing Partnerships, the LLC's, and certain
other entities, each such entity has been consolidated with the Operating
Partnership for financial reporting purposes. In regard to the Management
Companies, 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 EQR'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
EQR for its 1% interest in the Financing Partnerships has not been reflected in
the Consolidated Balance Sheets since such amounts are immaterial to the
Consolidated Balance Sheets.

3.          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. A land value is assigned based on the
purchase price if acquired separately or based on market research if acquired in
a merger or in a single or portfolio acquisition.

            For real estate 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
it is certain that the Operating Partnership will sell the property. Real estate
held for disposition is reported at the lower of its carrying amount or its
estimated fair value, less its cost to sell.

            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 and a five-year estimated life for initial furniture,
fixtures and equipment. Replacements inside a unit such as appliances and
carpeting, are depreciated over a five-year estimated life. 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, generally
five to ten years. Initial direct leasing costs are expensed as incurred as 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 depreciation
are removed from the respective accounts. Any gain or loss on sale of
disposition is recognized in accordance with accounting principles generally
accepted in the United States.

            The Operating Partnership classifies Properties under development
and/or expansion and properties in the lease up phase 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 $18.5
million and $19.4 million as of December 31, 1999 and 1998, respectively.

   (b)      CASH AND CASH EQUIVALENTS

         The Operating Partnership considers all demand deposits, money market
accounts and investments


                                      F-10
<PAGE>


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


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 line 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 $11.1 million and $8.2 million at December 31, 1999
and 1998, 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. The standard's effective date was
deferred by FASB Statement No. 137 to all fiscal quarters of all fiscal years
beginning after June 15, 2000. The Operating Partnership is planning to adopt
the standard once it is effective 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, 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, 1999 and 1998
was estimated to be approximately $87.0



                                      F-11
<PAGE>


                        ERP OPERATING LIMITED PARTNERSHIP

                                  (CONTINUED)


million and $91.8 million, respectively, compared to the Operating Partnership's
carrying value of $85 million and $88 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.

   (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, 1999 and 1998 was approximately $8.6
billion and $8.5 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 accounting principles generally accepted in the United
States, 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.



                                      F-12
<PAGE>


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


            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.

         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 accounting
principles generally accepted in the United States ("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. The Operating Partnership will adopt, effective January 1,
2000, the National Association of Real Estate Investment Trust's ("NAREIT")
updated recommended definition of FFO as approved in the fourth quarter of 1999.

         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 1999, 1998 or 1997.
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.

4.          BUSINESS COMBINATIONS

            In connection with the Wellsford Merger each outstanding common
share of beneficial interest of Wellsford was converted into .625 of a Common

Preferred Shares of Beneficial Interest were redesignated as EQR's 2,300,000
9.65% Series F Cumulative Redeemable Preferred Shares of Beneficial Interest,
$0.01 par value per share (the "Series F Preferred Shares").

            On the Wellsford Closing Date, 72 Properties containing 19,004 units
and other related assets were acquired for a total purchase price of
approximately $1 billion. The purchase price consisted of 10.8 million Common
Shares issued by EQR with a market value of $443.7 million, the liquidation
value of $157.5 million for the Series E Preferred Shares and the Series F
Preferred Shares, the assumption of mortgage indebtedness and unsecured notes in
the amount of $345 million, the assumption of other liabilities of approximately
$33.5 million and other merger related costs of approximately $23.4 million.
Upon contribution of the net assets by EQR to the Operating Partnership, the
Operating Partnership issued 10.8 million OP Units to EQR. In addition, the
Operating Partnership issued the Series E Cumulative Convertible Preference
Units (see Note 5) and the Series F Cumulative Redeemable Preference Units (see
Note 5).

            On the EWR Closing Date, 53 Properties containing 15,331 units and
three Properties under construction or expansion containing 953 units and other
related assets were acquired for a total purchase price of approximately $1.2
billion. In connection with the EWR Merger, as of the EWR Closing Date, each
outstanding common share of beneficial interest of EWR was converted into .50 of
a Common Share of EQR. The purchase price consisted of 10.3 million Common
Shares issued by EQR with a market value of approximately $501.6 million,
issuance of approximately 2.2 million Operating Partnership OP Units in exchange
for approximately 4.4 million EWR Operating Partnership OP Units at a market
value of approximately $107.3 million, the assumption of mortgage indebtedness
and unsecured notes in the amount of $498 million, the assumption of other
liabilities of approximately $28.2 million and other EWR Merger related costs of
approximately $16.7 million. Upon contribution of the net assets by EQR to the
Operating Partnership, the Operating Partnership issued 10.3 million OP Units to
EQR.

         In connection with the MRY Merger, each outstanding common share of
beneficial interest of MRY was converted into 0.53 of a Common Share of EQR. In
addition, MRY spun-off certain assets and liabilities to Merry Land Properties,
Inc. ("MRYP Spinco"). As partial consideration for the transfer, the Operating
Partnership extended a $25 million, one year, non-revolving loan to MRYP Spinco
pursuant to a Senior Debt Agreement. As of December 31, 1999, the debt agreement
was no longer outstanding.


            In addition, MRY Series A Cumulative Convertible Preferred Shares of
Beneficial Interest were redesignated as EQR's 164,951 Series H Cumulative

5.          PARTNERS' CAPITAL

            As of December 31, 1999 and 1998, OP Units outstanding totaled
139,934,540 and 131,417,938, respectively. The limited partners of the Operating
Partnership as of December 31, 1999 and 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 12,483,742 and 13,187,929 OP Units, respectively. As of December 31, 1999 and
1998, EQR (as the general partner) had an approximate 91.08% and 89.96%
interest, respectively, and the Limited Partners had an approximate 8.92% and
10.04% interest, respectively, in the Operating Partnership.

         In regards to the general partner, net proceeds from the various equity
offerings of EQR, have been contributed by EQR 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 EQR (as general
partner) and the Limited Partners (to the extent represented by OP Units) to
account for the change in their respective percentage ownership of the equity of
the Operating Partnership.

            The following table presents the changes in the Operating
Partnership's issued and outstanding OP Units for the years ended December 31,
1999, 1998 and 1997:

(1)      On the fifth anniversary of the respective issuance (the "Redemption
         Date"), the Series A Junior Convertible Preference Units shall be
         automatically converted into OP Units based upon the conversion rate.
         Prior to the Redemption Date, the Operating Partnership or the holders
         may elect to convert the Series A Junior Convertible Preference Units
         to OP Units under certain circumstances based upon the conversion rate.

(2)      On or after the tenth anniversary of the issuance (the "Redemption
         Date"), the Series B Junior Convertible Preference Units may be
         converted into OP Units at the option of the Operating Partnership
         based on the contractual conversion rate. Prior to the Redemption Date,
         the holders may elect to convert the Series B Junior Convertible
         Preference Units to OP Units under certain circumstances based on the
         contractual conversion rate. The contractual conversion rate is based
         upon a ratio dependent upon the closing price of EQR's Common Shares.
         The current rate at December 31, 1999 was 0.510204.

8.       COMMITMENTS TO ACQUIRE/DISPOSE OF REAL ESTATE

         As of December 31, 1999, in addition to the Property that was
subsequently acquired as discussed in Note 22 of the Notes to Consolidated
Financial Statements, the Operating Partnership entered into separate agreements

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (Continued)

         As of December 31, 1999, in addition to the Properties that were
subsequently disposed of as discussed in Note 22 of the Notes to Consolidated
Financial Statements, the Operating Partnership entered into separate agreements
to dispose of fourteen multifamily properties containing 3,056 units to
unaffiliated parties. The Operating Partnership expects a combined disposition
price of approximately $138.9 million.

         The closings of these pending transactions are subject to certain
contingencies and conditions; therefore, there can be no assurance that these
transactions will be consummated or that the final terms thereof will not differ
in material respects from those summarized in the preceding paragraphs.

9.       INVESTMENT IN MORTGAGE NOTES, NET

         In 1995, the Operating Partnership made an $89 million investment in
partnership interests and subordinated mortgages collateralized by 21 of the
Properties. These 21 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 represented a one time payment for
an interest rate protection agreement and $0.3 million represented 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.

         As of December 31, 1999 and 1998, the second mortgage notes had a
combined principal balance of approximately $17.5 million and $21.7 million,
respectively, and currently 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, 1999 and 1998, the third mortgage
notes had a combined principal balance of approximately $71.1 million and $71.1
million, respectively, and currently 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, 1999 and 1998 was $4.8 million and $6 million,
respectively. During 1999, 1998 and 1997, the Operating Partnership amortized
$1.2 million, $3.0 million and $3.1 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.

10.      DEPOSITS-RESTRICTED

         Deposits-restricted as of December 31, 1999 primarily included the
following:

         -     a deposit in the amount of $25 million held in a third party
               escrow account to provide collateral for third party
               construction financing in connection with two separate joint
               venture agreements;
          -    approximately $48.9 million was held in third party escrow
               accounts, representing proceeds received in connection with the
               Operating Partnership's disposition of three properties and
               earnest money deposits made for one additional acquisition;

          -    approximately $29.9 million was for tenant security, utility
               deposits, and other deposits for certain of the Operating
               Partnership's Properties; and
          -    approximately $7.5 million of other deposits.

         Deposits-restricted as of December 31, 1998 primarily included the

               financing in connection with the Joint Venture Agreement;
          -    approximately $22.2 million held in third party escrow accounts
               representing proceeds received in connection with the Operating
               Partnership's disposition of four properties;
          -    approximately $15.3 million for tenant security and utility
               deposits for certain of the Operating Partnership's Properties;
               and
          -    approximately $11.8 million of other deposits.

11.      MORTGAGE NOTES PAYABLE

         As of December 31, 1999, the Operating Partnership had outstanding
mortgage indebtedness of approximately $2.9 billion encumbering 545 of the
Properties. The carrying value of such Properties (net of accumulated
depreciation of $416 million) was approximately $4.7 billion. The mortgage notes
payables are generally due in monthly installments of principal and interest.

         During the year ended December 31, 1999 the Operating Partnership:

          -    as part of the LFT Merger, assumed the outstanding mortgage
               balances on 342 Properties in the aggregate amount of $499.7
               million;
          -    assumed the outstanding mortgage balances on eight additional
               properties acquired during 1999 in the aggregate amount of $69.9
               million;
          -    repaid the outstanding mortgage balances on 31 Properties in the
               aggregate amount of $60.8 million. In connection with the above
               transactions, the Operating Partnership incurred prepayment
               penalties of $0.5 million, which have been classified as losses
               on early extinguishment of debt;
          -    refinanced the debt on four existing properties totaling $44.9
               million with new mortgage indebtedness totaling $62.9 million;
          -    obtained new mortgage financing on eleven previously unencumbered
               properties in the amount of $126.5 million;
          -    refinanced the debt totaling $120.8 million on ten existing
               properties. In addition, five previously unencumbered properties
               cross-collateralize each of the new mortgage notes;
          -    refinanced the debt on two existing properties and consequently
               sold its lender position to a third party, thus receiving
               additional net cash proceeds of approximately $2.6 million. The
               bond indebtedness on these two properties is now unsecured and is
               classified as notes, net at December 31, 1999;
          -    refinanced the debt on one existing property and consequently
               sold its lender position to a third party, thus receiving
               additional cash proceeds of approximately $13.7 million; and
          -    sold the debt on one property totaling $12.5 million in
               conjunction with a real estate disposition.

         As of December 31, 1999, scheduled maturities for the Operating
Partnership's outstanding mortgage indebtedness are at various dates through
October 1, 2033. The interest rate range on the Operating Partnership's mortgage
debt was 4.00% to 10.13% at December 31, 1999. During the year ended December
31, 1999, the effective interest cost on all of the Operating Partnership's debt
was 7.05%.

         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.

         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. The interest rate range on the Operating Partnership's mortgage
debt was 3.00% to 10.00% at December 31, 1998. During the year ended December
31, 1998, the effective interest cost on all of the Operating Partnership's debt
was 7.10%.

         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.

         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, 1999, the
aggregate notional

amounts of these agreements were approximately $133.4 million, $27.7 million and
$9.1 million. As of December 31, 1998, the aggregate notional amounts of these
agreements were approximately $135.1 million, $28.0 million and $9.2 million.
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, 1999, the
aggregate notional amounts of these agreements were approximately $133.4
million, $27.7 million, and $9.1 million. As of December 31, 1998, the aggregate
notional amounts of these agreements were approximately $135.1 million, $28.0
million and $9.2 million. 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 swap agreement for
a notional amount of $228 million, for which it will receive payments if the PSA
index exceeds 8.00%, that terminates on December 1, 2000. 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 its 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%. 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 canceled in November 1998 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.

         In October 1999, the Operating Partnership settled on a $50 million
treasury lock and received $1.38 million. This settlement is being amortized
over the life of the financing for the eleven previously unencumbered Properties
that occurred in July 1999.

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

         The fair value of these instruments, discussed above, as of December
31, 1999 approximates their carrying or contract values.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (Continued)

         On February 3, 1998, the Operating Partnership filed a Form S-3
Registration Statement to register $1 billion of debt securities. The SEC
declared this registration statement effective on February 27, 1998. As of
December 31, 1999, $430 million remained outstanding under this registration
statement.

         During the year ended December 31, 1999, the Operating Partnership:

          -    issued $300 million of redeemable unsecured fixed rate notes (the
               "June 2004 Notes") in connection with the Debt Shelf Registration
               in a public debt offering (the "Ninth Public Debt Offering"). The
               June 2004 Notes were issued at a discount, which is being
               amortized over the life of the notes on a straight-line basis. As
               of December 31, 1999, the unamortized discount balance was
               approximately $0.2 million. The June 2004 Notes are due June 23,
               2004. The annual interest rate on the June 2004 Notes is 7.10%,
               which is payable semiannually in arrears on December 23 and June
               23, commencing December 23, 1999. The Operating Partnership
               received net proceeds of approximately $298.0 million in
               connection with this issuance;
          -    repaid its $125 million fixed rate notes that matured on May 15,
               1999 and its $25 million floating rate notes that matured on
               November 24, 1999;
          -    refinanced the bond indebtedness collateralized by four existing
               properties. The bond indebtedness on all four properties totaling
               $75.8 million is now unsecured;
          -    pursuant to the LFT Merger, assumed an unsecured term note in the
               approximate amount of $2.3 million and paid it off the same day;
               and
          -    refinanced the bond indebtedness collateralized by two existing
               properties. The bond indebtedness on both properties totaling
               $16.4 million is now unsecured.

each counterparty is a major U.S. financial institution and the Operating
Partnership does not anticipate their non-performance.

13.      LINES OF CREDIT

         On August 12, 1999 the Operating Partnership obtained a new three year
$700 million unsecured revolving credit facility, with Bank of America
Securities LLC and Chase Securities Inc. acting as joint lead arrangers,
maturing August 11, 2002. The new line of credit replaced the Operating
Partnership's $500 million unsecured revolving credit facility, as well as the
$120 million unsecured revolving credit facility which the Company assumed in
the MRY Merger. The prior existing revolving credit facilities were repaid in
full and terminated upon the closing of the new facility. Advances under the
credit facility bear interest at variable rates based upon LIBOR at various
interest periods, plus a certain spread dependent upon the Operating
Partnership's credit rating. As of December 31, 1999 and 1998, $300 million and
$290 million, respectively, was outstanding and $65.8 million and $12 million,
respectively, was restricted on the lines of credit. During the years ended
December 31, 1999 and 1998, the weighted average interest rate was 6.42% and
6.47%, respectively.

         Pursuant to the LFT Merger, the Operating Partnership assumed a line of
credit that had an outstanding balance of approximately $26.4 million. On
October 1, 1999, the Operating Partnership repaid the outstanding balance and
terminated this facility.

          $28.6 million;
     o    the repayment of the outstanding mortgage balances on 31 properties
          totaling $60.8 million;
     o    the mortgage financing of eleven previously unencumbered Properties
          for $126.5 million;
     o    the mortgage refinancing of eight properties increasing mortgage
          indebtedness by $21.8 million (net);

          This would result in 139,461,669 OP Units outstanding on January 1,
1999. In management's opinion, the Summarized Pro Forma Condensed Statement of
Operations does not purport to present what actual results would have been had
the above transactions occurred on January 1, 1999, or to project results for
any future period. The amounts presented in the following statement are in

16.      EMPLOYEE SHARE PURCHASE PLAN

         Under EQR's Employee Share Purchase Plan certain eligible officers,
trustees and employees of EQR may annually acquire up to $100,000 of Common
Shares of EQR. The aggregate number of Common Shares available under the
Employee Share Purchase Plan shall not exceed 1,000,000, subject to adjustment
by the Board of Trustees. The Common Shares may be purchased 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 price for a
share for all the business days in the quarter. During 1997, EQR issued 84,183
Common Shares at net prices that ranged from $35.63 per share to $42.08 per
share and raised approximately $3.2 million in connection therewith. During
1998, EQR issued 93,521 Common Shares at net prices that ranged from $35.70 per
share to $42.71 per share and raised approximately $3.7 million in connection
therewith. During 1999, EQR issued 147,885 Common Shares at net prices that
ranged from $34.37 per share to $36.71 per share and raised approximately $5.2
million in connection therewith. The net proceeds were contributed to the
Operating Partnership in exchange for OP Units.

17.      DISTRIBUTION REINVESTMENT AND SHARE PURCHASE PLAN

         The Distribution Reinvestment and Share Purchase Plan (the "DRIP Plan")
of EQR 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 EQR, 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 net proceeds from any Common Share issuances are
contributed to the Operating Partnership in exchange for OP Units.

18.      EMPLOYEE TRANSACTIONS

         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
outstanding balance on these loans in the aggregate was $4.7 million and $4.9
million for the years ended December 31, 1999 and 1998, respectively. 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, 1999, the outstanding principal balance
on additional notes issued to Mr. Crocker and three other officers was
approximately $1.2 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, 1999, Mr. Crocker paid a
principal installment on his note in the amount of $80,570 and repaid another
note in full in the amount of $100,000. The notes are recourse to Mr. Crocker
and the four other officers and are collateralized by pledges of Company options
and share awards.

         Mr. Crocker and Gerald A. Spector, Executive Vice President and Chief
Operating Officer of the Company, have entered into Deferred Compensation
Agreements with the Company which provide both with a salary benefit after their
respective termination of employment with the Company, under certain
circumstances. In addition, Mr. Crocker also has entered into a Share
Distributions Agreement with the Company whereby he was issued options to
purchase 100,000 Common Shares under the terms of the Fifth Amended Option and
Award Plan. Upon exercise of these options, Mr. Crocker will be entitled to
receive dividends on these shares as if they had been outstanding from the grant
date through the exercise date. The Operating Partnership has recognized $1.1
million, $0.8 million and $0.7 million of compensation expense for the years
ended December 31, 1999, 1998 and 1997, respectively, related to these
agreements.

         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, on behalf of the Company,
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 $1.4 million and

laws or regulations on its current Properties or on properties that it may

</TABLE>


(1)      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.

(2)      The Operating Partnership 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 a reportable
         segment as provided for in Statement No. 131. Interest expense on debt
         is not allocated to individual Properties, even if the Properties
         secure such debt.
