         DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

         In the normal course of business, the Operating Partnership is
exposed to the effect of interest rate changes. The Operating Partnership
limits these risks by following established risk management policies and
procedures including the use of derivatives.

         The Operating Partnership has a policy of only entering into
contracts with major financial institutions based upon their credit ratings
and other factors. When viewed in conjunction with the underlying and
offsetting exposure that the derivatives are designed to hedge, the Operating
Partnership has not sustained a material loss from those instruments nor does
it anticipate any material adverse effect on its net income or financial
position in the future from the use of derivatives.

         On January 1, 2001, the Operating Partnership adopted SFAS No.
133/138, which requires an entity to recognize all derivatives as either
assets or liabilities in the statement of financial position and to measure
those instruments at fair value. Additionally, the fair value adjustments
will affect either partners' capital or net income depending on whether the
derivative instruments qualify as a hedge for accounting purposes and, if so,
the nature of the hedging activity. When the terms of an underlying
transaction are modified, or when the underlying transaction is terminated or
completed, all changes in the fair value of the instrument are
marked-to-market with changes in value included in net income each period
until the instrument matures. Any derivative instrument used for risk
management that does not meet the hedging criteria is marked-to-market each
period.

         As of January 1, 2001, the adoption of the new standard resulted in
derivative instruments reported on the balance sheet as liabilities of
approximately $6.6 million; an adjustment of approximately $5.3 million to
"Accumulated Other Comprehensive Income", which are gains and losses not
affecting retained earnings in the Consolidated Statement of Partners'
Capital; and a charge of approximately $1.3 million as a cumulative effect of
change in accounting principle in the Consolidated Statement of Operations.

         The Operating Partnership employs derivative financial instruments
to hedge qualifying anticipated transactions. Gains and losses are deferred
and recognized in net income in the same period that the underlying
transaction occurs, expires or is otherwise terminated. As of March 31, 2001,
there were approximately $17.0 million in deferred losses, net, included in
accumulated other comprehensive income.

         As of March 31, 2001, the Operating Partnership has entered into
swaps, which have been designated as cash flow hedges with an aggregate
notional amount of $626.4 million at interest rates ranging from 3.65125% to
6.15% maturing at various dates ranging from 2003 to 2007 with a net
liability fair value of $16.5 million; and swaps which have been designated
as fair value hedges with an aggregate notional amount of $176.4 million at
interest rates ranging from 4.458% to 4.830% maturing at various dates
ranging from 2003 to 2004 with a net asset fair value of $5.6 million.

         On March 31, 2001, the net derivative instruments were reported at
their fair value as other liabilities of approximately $10.9 million. Within
the next twelve months the Operating Partnership expects to recognize an
estimated $4.0 million of accumulated other comprehensive income as
additional interest expense.

</TABLE>

         As of March 31, 2001, EQR (as the general partner) had an
approximate 91.64% interest and the Limited Partners had an approximate 8.36%
interest in the Operating Partnership. The limited partners of the Operating
Partnership as of March 31, 2001 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
12,186,865 OP Units.

         EQR contributes all net proceeds from the various equity offerings
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 (on a one-for-one common share per
OP Unit basis), 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.

outstanding Junior Convertible Preference Units as of March 31, 2001 and

</TABLE>

         On February 23, 2001, the Operating Partnership entered into a joint
venture with an unaffiliated joint venture partner ("JVP"). At closing, the
Operating Partnership sold and/or contributed eleven wholly owned properties
containing 3,011 units valued at $202.5 million to the joint venture
encumbered with $20.2 million in mortgage loans obtained on February 16,
2001. An additional $123.6 million of mortgage loans was obtained by the
joint venture. The JVP contributed cash in an amount equal to 75% of the
equity in the joint venture, which was then distributed to the Operating
Partnership. The Operating Partnership retained a 25% interest in the joint
venture along with the right to manage the properties. In accordance with the
respective joint venture organization documents, the Operating Partnership
and the JVP both shall have the right, but not the obligation, to infuse
additional cash into the joint venture. There are no other agreements that
require the Operating Partnership or the JVP to infuse cash into each joint
venture. In addition, the Operating Partnership and the JVP have not
guaranteed the mortgage indebtedness of the joint venture. As a result, the
Operating Partnership recognized 75% of the gain on the sales and/or
contributions of property to the joint venture, which totaled approximately
$36.5 million. The Operating Partnership has classified its initial $3.4
million 25% interest in the joint venture (at carryover basis) as investments
in unconsolidated entities and accounted for it under the equity method of
accounting.

         In addition, during the three months ended March 31, 2001, the
Operating Partnership sold a vacant parcel of land in Richmond, VA for $11.2
million.

6.       COMMITMENTS TO ACQUIRE/DISPOSE OF REAL ESTATE

         As of March 31, 2001, the Operating Partnership entered into a
separate agreement to acquire one multifamily property containing 125 units
from an unaffiliated party. The Operating Partnership expects a purchase
price of approximately $13.5 million.

         As of March 31, 2001, in addition to the Properties that were
subsequently disposed of as discussed in Note 15 of the Notes to Consolidated
Financial Statements, the Operating Partnership entered into separate
agreements to dispose of seventeen multifamily properties containing 3,161
units to unaffiliated parties. The Operating Partnership expects a combined
disposition price of approximately $137.2 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.

13.      COMMITMENTS AND CONTINGENCIES

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

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

         In regards to the funding of Properties in the development and/or
earnout stage and the joint venture agreements with two multifamily
residential real estate developers, the Operating Partnership funded a total
of $26.4 million during the quarter ended March 31, 2001. During the
remainder of 2001, the Operating Partnership expects to fund approximately
$70.2 million in connection with these Properties. In connection with one
joint venture agreement, the Operating Partnership has an obligation to fund
up to an additional $17.5 million to guarantee third party construction
financing. As of March 31, 2001, the Operating Partnership has 19 projects
under development with estimated completion dates ranging from June 30, 2001
through March 31, 2003. At any time following the completion of construction
of any development property, the Operating Partnership's joint venture
partners have the right to cause the Operating Partnership to acquire their
respective interests in the completed projects at a mutually agreeable price.
If the Operating Partnership and the joint venture partner are unable to
agree on a price, both parties will obtain appraisals. If the appraised
values vary by more than 10%, both the


                                      15
<PAGE>

Operating Partnership and the joint venture partner will agree on a third
appraiser to determine which original appraisal is closest to its
determination of value.

         In connection with the Wellsford Merger, the Operating Partnership
provided a credit enhancement with respect to certain tax-exempt bonds issued
to finance certain public improvements at a multifamily development project.
As of March 31, 2001, this enhancement was still in effect at a commitment
amount of $12.7 million.

(1)    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 fee and asset management activity, furniture
       rental/sales activity, interest income earned on short-term investments
       and investment in mortgage notes, investment in technology entities,
       income earned from investments in unconsolidated entities, general and
       administrative expenses, and interest expense on mortgage notes payable,
       unsecured note issuances and lines of credit. The Operating Partnership's
       fee and asset management activity and furniture rental/sales activities
       are immaterial and do not meet the threshold requirements of a reportable
       segment as provided for in SFAS No. 131. Interest expense on debt is not
       allocated to individual Properties, even if the Properties secure such
       debt. Further, income allocated to Minority Interests is not allocated to
       the Properties.

         In addition, the Operating Partnership sold and/or contributed
eleven wholly owned Properties containing 3,011 units to a joint venture
entity during the quarter ended March 31, 2001. The Operating Partnership
retained a 25% interest along with the rights to manage the joint venture
Properties.



                                      19
<PAGE>


         The Operating Partnership's overall results of operations for the
quarters ended March 31, 2001 and 2000 have been significantly impacted by
the Operating Partnership's acquisition and disposition activity. The
significant changes in revenues and expenses can primarily be attributed to
the acquisition of Globe, the 2001 and the 2000 Acquired Properties,
partially offset by the disposition of the 2001 and the 2000 Disposed
Properties. This impact is discussed in greater detail in the following
paragraphs.

Properties that the Operating Partnership owned for all of the quarter ended
March 31, 2001 and March 31, 2000 (the "First Quarter 2001 Same Store
Properties"), which represented 188,220 units, also impacted the Operating
Partnership's results of operations and are discussed as well in the
following paragraphs.

   COMPARISON OF QUARTER ENDED MARCH 31, 2001 TO QUARTER ENDED MARCH 31, 2000

         For the quarter ended March 31, 2001, income before allocation to
Minority Interests, income from investments in unconsolidated entities, net
gain on sales of real estate, extraordinary items and cumulative effect of
change in accounting principle increased by approximately $16.6 million when
compared to the quarter ended March 31, 2000.

         Rental income from the First Quarter 2001 Same Store Properties
increased by approximately $22.8 million to $439.9 million or 5.46% 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. For the
remainder of 2001, the Operating Partnership expects to achieve rental income
increases of 4.5% to 5.0% from Same Store Properties. These estimated
increases are subject to certain risks and uncertainties including, but not
limited to, maintaining an overall average occupancy rate of 95%.

         Property operating expenses from the First Quarter 2001 Same Store
Properties, which include property and maintenance, real estate taxes and
insurance and an allocation of property management expenses, increased
approximately $8.9 million or 5.97%. The increase in "same store" expenses is
primarily attributable to a $3.6 million, or 14.8% increase in utilities and
a $2.1 million, or 5.7% increase in payroll. For the remainder of 2001, the
Operating Partnership expects to maintain expense growth at no more than
4.25% to 4.75%.

         Rental income from non-First Quarter 2001 Same Store Properties
increased by approximately $17.8 million primarily as a result of revenue
from the Globe corporate housing business and the acquisition of Properties
during the periods presented. The Operating Partnership expects similar
trends in the future subject to certain risks and uncertainties including
that any new acquisitions perform at the Operating Partnership's pro forma
expectations.

         Interest and other income increased by approximately $3.0 million,
primarily as a result of disposition proceeds earning interest in various tax
deferred 1031 exchange accounts. These proceeds are invested in money market
investments until the Operating Partnership purchases additional multi-family
properties.

         Property management represents expenses associated with the
self-management of the Operating Partnership's Properties. These expenses
decreased by approximately $0.2 million. The Operating Partnership continues
to acquire properties in major metropolitan areas and dispose of assets in
smaller multi-family rental markets where the Operating Partnership does not
have a significant management presence. As a result, the Operating
Partnership is able to achieve economies of scale by not increasing off-site
management expenses as it acquires additional properties.

         Fee and asset management revenues and fee and asset management
expenses increased as a result of the Operating Partnership continuing to
manage Properties that were sold and/or contributed to various joint venture
entities. As of March 31, 2001, the Operating Partnership currently manages
20,300 units for third


                                      20

parties and the joint venture entities.

         Furniture income and furniture expenses are associated with the
operation of the furniture rental business assumed in connection with the
Globe acquisition, which occurred in July 2000. Furniture expenses include a
depreciation charge on furniture held in inventory.

         Interest expense, including amortization of deferred financing
costs, increased approximately $0.2 million. The effective interest cost on
all of the Operating Partnership's indebtedness for the quarter ending March
31, 2001 was 7.07% as compared to 7.17% for the quarter ended March 31, 2000.
For the remainder of 2001, the Operating Partnership expects interest rates
to decrease slightly due to lower variable rates. In connection with the
refinancing of $280.0 million of indebtedness, the Operating Partnership
expects to incur interest costs approximating 7.5% per annum.

         General and administrative expenses, which include corporate
operating expenses, increased approximately $0.1 million between the periods
under comparison. However, by gaining certain economies of scale with a much
larger operation, these expenses as a percentage of total revenues were 1.26%
for the quarter ended March 31, 2001 compared to 1.39% of total revenues for
the quarter ended March 31, 2000.

         Net gain on sales of real estate increased approximately $21.8
million between the periods under comparison. This increase is primarily the
result of additional Properties sold during the quarter ended March 31, 2001,
which included fifteen wholly owned Properties, eleven joint venture
Properties (75% gain recognition) and one land sale as compared to eleven
wholly owned Properties sold in the quarter ended March 31, 2000.

LIQUIDITY AND CAPITAL RESOURCES

         As of January 1, 2001, the Operating Partnership had approximately
$23.8 million of cash and cash equivalents and the amounts available on the
Operating Partnership's lines of credit was $400 million, of which $53.5
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 March 31, 2001 was approximately $104.8 million
and the amounts available on the Operating Partnership's lines of credit was
$755 million, of which $54.9 million was restricted.

         Part of the Operating Partnership's strategy in funding the purchase
of multifamily properties, funding its Properties in the development and/or
earnout stage and the funding of the Operating Partnership's investment in
two joint ventures with multifamily real estate developers is to utilize its
lines of credit and to subsequently repay the lines of credit from the
disposition of Properties or the issuance of additional equity or debt
securities. Utilizing this strategy during the first three months of 2001,
the Operating Partnership:

      o  disposed of fifteen properties and a vacant parcel of land and received
         net proceeds of $115.4 million;

      o  issued $300 million of unsecured debt receiving net proceeds of $297.4
         million;

      o  sold and/or contributed eleven properties to a joint venture and
         received net proceeds of $190.0 million;

      o  issued $35 million of two new series of Preference Interests and
         received net proceeds of $34.1 million.

All of these proceeds were utilized to either:

      o  repay the lines of credit;

      o  repay mortgage indebtedness on selected Properties;

      o  invest in unconsolidated entities;

      o  purchase additional properties.

During the quarter ended March 31, 2001, the Operating Partnership:

      o  repaid approximately $176.7 million of mortgage indebtedness;

      o  invested $1 million in a corporate entity;

      o  loaned $2.6 million to an unconsolidated entity;

      o  funded $26.4 million related to the development, earnout and joint
         venture agreements.

</TABLE>

Subsequent to March 31, 2001 and through May 1, 2001, the Operating Partnership:

      o  disposed of four Properties consisting of 658 units for approximately
         $24.7 million;

      o  repaid $6.7 million of mortgage debt at or prior to maturity and/or
         disposition of a Property;

      o  funded $5.9 million related to the development, earnout and joint
         venture agreements;

      o  disposed of $0.9 million of mortgage debt assumed by the purchaser in
         connection with the disposition of one property.

         During the remainder of 2001, the Operating Partnership expects to
fund approximately $70.2 million related to the development, earnout and
joint venture agreements. In connection with one joint venture agreement, the
Operating Partnership has an obligation to fund up to an additional $17.5
million to guarantee third party construction financing. As of March 31,
2001, the Operating Partnership has 19 projects under development with
estimated completion dates ranging from June 30, 2001 through March 31, 2003.
At any time following the completion of construction of any development
property, the Operating Partnership's joint venture partners have the right
to cause the Operating Partnership to acquire their respective interests in
the completed projects at a mutually agreeable price. If the Operating
Partnership and the joint venture partner are unable to agree on a price,
both parties will obtain appraisals. If the appraised values vary by more
than 10%, both the Operating Partnership and the joint venture partner will
agree on a third appraiser to determine which original appraisal is closest
to its determination of value.

         During the quarter ended March 31, 2001, the Operating Partnership's
total improvements to real estate approximated $28.2 million. Of this amount,
approximately $4.5 million, or $89 per unit, related to capital improvements
and major repairs for the 1999, 2000 and 2001 Acquired Properties. Capital
improvements and major repairs for all of the Operating Partnership's
pre-1999 Acquired Properties approximated $9.9 million or $64 per unit.
Capital spent for replacement-type items approximated $11.4 million, or $56
per unit. In addition, approximately $1.7 million was spent on seven specific
assets related to major renovations and repositioning of these assets. Also
included in total improvements to real estate was approximately $0.7 million
on commercial/other assets and Partially Owned Properties.


                                      22
<PAGE>

Such improvements to real estate were primarily funded from net cash provided
by operating activities. Total improvements to real estate budgeted for the
remainder of 2001 is estimated to be approximately $110.0 million.

         Also included in total capital expenditures for the Operating
Partnership was approximately $1.8 million for non-real estate additions such
as computer software, computer equipment, and furniture and fixtures and
leasehold improvements to the Operating Partnership's property management
offices and its corporate offices. Such additions to non-real estate property
were primarily funded from net cash provided by operating activities. Total
additions to non-real estate property budgeted for the remainder of 2001 are
estimated to be approximately $4.2 million.

         The Operating Partnership, through its Globe subsidiary, has a
policy of capitalizing expenditures made for rental furniture and property
and equipment. Globe purchases furniture to replace furniture that has been
sold and to maintain adequate levels of rental furniture to meet existing and
new customer needs. Expenditures for property and equipment that
significantly enhance the value of existing assets or substantially extend
the useful life of an asset are also capitalized. Expenditures for ordinary
maintenance and repairs related to property and equipment are expensed as
incurred. For the quarter ended March 31, 2001, total additions to rental
furniture approximated $6.3 million and property and equipment approximated
$0.7 million. Total additions to rental furniture and property and equipment
budgeted for the remainder of 2001 are estimated to be approximately $18.0
million.

         Total distributions paid in April 2001 amounted to approximately
$143.3 million, which included distributions declared for the quarter ended
March 31, 2001.

         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 lines of credit. The Operating
Partnership considers its cash provided by operating activities to be
adequate to meet operating requirements and payments of distributions. The
Operating Partnership also expects to meet its long-term liquidity
requirements, such as scheduled 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.

         The Operating Partnership has a revolving credit facility with Bank
of America Securities LLC and Chase Securities Inc. acting as joint lead
arrangers to provide the Operating Partnership with potential borrowings of
up to $700 million. As of May 1, 2001, no amounts were outstanding under this
facility.

         In connection with the Globe acquisition, the Operating Partnership
assumed a revolving credit facility with Fifth Third Bank with potential
borrowings of up to $55.0 million. As of May 1, 2001, no amounts were
outstanding under this facility.

         In connection with the Wellsford Merger, the Operating Partnership
provided a credit enhancement with respect to certain tax-exempt bonds issued
to finance certain public improvements at a multifamily development project.
As of May 1, 2001, this enhancement was still in effect at a commitment
amount of $12.7 million.

FUNDS FROM OPERATIONS

         Funds from Operations ("FFO") represents net income (loss) (computed
in accordance with accounting principles generally accepted in the United
States ("GAAP")), excluding gains or losses from


                                      23
<PAGE>

sales of property and investments in technology segments, plus depreciation
and amortization, and after adjustments for unconsolidated partnerships and
joint ventures. Adjustments for unconsolidated partnerships and joint
ventures will be calculated to reflect funds from operations on the same
basis.

         The Operating Partnership believes that FFO is helpful to investors
as a supplemental measure of the operating performance of a real estate
company because, along with cash flows from operating activities, financing
activities and investing activities, it provides investors an understanding
of the ability of the Operating Partnership to incur and service debt and to
make capital expenditures. FFO in and of itself does not represent cash
generated from operating activities in accordance with GAAP and therefore
should not be considered an alternative to net income as an indication of the
Operating Partnership's performance or to net cash flows from operating
activities as determined by GAAP as a measure of liquidity and is not
necessarily indicative of cash available to fund cash needs. The Operating
Partnership's calculation of FFO may differ from the methodology for
calculating FFO utilized by other real estate companies and may differ as a
result of differences between the Operating Partnership's and other real
estate company's accounting policies for replacement type items and,
accordingly, may not be comparable to such other real estate companies.

         For the quarter ended March 31, 2001, FFO available to OP
Units-basic increased by $22.3 million, or 13.1% when compared to the quarter
ended March 31, 2000.

         The following is a reconciliation of net income to FFO available to
OP Units for the quarters ended March 31, 2001 and 2000 (amounts in thousands
except per OP Unit amounts):
