2.     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       BASIS  OF PRESENTATION

       The accompanying unaudited condensed consolidated financial statements
have been prepared in accordance with accounting principles generally accepted
in the United States for interim financial information and with the instructions
to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include
all of the information and footnotes required by accounting principles generally
accepted in the United States for complete financial statements. In the opinion
of management, all adjustments (consisting of normal recurring accruals) and
certain reclassifications considered necessary for a fair presentation have been
included. Certain reclassifications have been made to the prior period financial
statements in order to conform to the current year presentation. Operating
results for the nine months ended September 30, 2001 are not necessarily
indicative of the results that may be expected for the year ended December 31,
2001.

       The balance sheet at December 31, 2000 has been derived from the audited
financial statements at that date but does not include all of the information
and footnotes required by accounting principles generally accepted in the United
States for complete financial statements.

       For further information, including definitions for capitalized terms,
refer to the consolidated financial statements and footnotes thereto included in
the Company's annual report on Form 10-K for the year ended December 31, 2000.

       DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

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

                                        6
<Page>

       The Company 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 Company 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 Company 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 shareholders' equity
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 Shareholders'
Equity; and a charge of approximately $1.3 million as a cumulative effect of
change in accounting principle in the Consolidated Statement of Operations.

       The Company 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 September 30, 2001, there were approximately $25.4
million in deferred losses, net, included in accumulated other comprehensive
income.

       At September 30, 2001, the Company had 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 $27.1
million; and swaps which have been designated as fair value hedges with an
aggregate notional amount of $296.4 million at interest rates ranging from
4.458% to 7.25% maturing at various dates ranging from 2003 to 2005 with a net
asset fair value of $13.1 million.

       On September 30, 2001, the net derivative instruments were reported at
their fair value as other liabilities of approximately $14.0 million. Within the
next twelve months the Company expects to recognize an estimated $7.6 million of
accumulated other comprehensive income as additional interest expense.

       OTHER

       In June 2001, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 141, BUSINESS COMBINATIONS, and SFAS No. 142, GOODWILL AND OTHER
INTANGIBLE ASSETS. SFAS Nos. 141 and 142 require companies to account for all
business combinations using the purchase method of accounting and to eliminate
the amortization of goodwill in favor of a periodic impairment based approach.
SFAS Nos. 141 and 142 will be effective for fiscal years beginning after
December 15, 2001. The Company will adopt the standards effective January 1,
2002, and does not anticipate that the adoptions will have a material impact on
the Company's financial condition and results of operations.

       In August 2001, the FASB issued SFAS No. 144, ACCOUNTING FOR THE
IMPAIRMENT OR DISPOSAL OF LONG-LIVED ASSETS, which is effective for fiscal
years beginning after December 15, 2001. The Company will adopt the standard
effective January 1, 2002, and does not anticipate that the adoption will
have a material impact on the Company's financial condition and results of
operations.

       On February 23, 2001, the Company entered into a joint venture with an
unaffiliated joint venture partner ("JVP"). At closing, the Company 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 Company. The Company 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 Company 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

                                       12
<Page>

require the Company or the JVP to infuse cash into each joint venture. In
addition, the Company and the JVP have not guaranteed the mortgage indebtedness
of the joint venture. As a result, the Company recognized 75% of the gain on the
sales and/or contributions of property to the joint venture, which totaled
approximately $36.4 million. The Company 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.

       On May 17, 2001, the Company sold its entire interest in one
Unconsolidated Property containing 74 units for approximately $0.4 million.

6.     Commitments to Acquire/Dispose of Real Estate

       At September 30, 2001, in addition to the Property that was subsequently
acquired as discussed in Note 16 below, the Company had entered into separate
agreements to acquire two multifamily properties containing 469 units from
unaffiliated parties. The Company expects a combined purchase price of
approximately $76.5 million, including the assumption of mortgage indebtedness
of approximately $45.8 million.

       At September 30, 2001, in addition to the Properties that were
subsequently disposed of as discussed in Note 16 below, the Company had entered
into separate agreements to dispose of seven multifamily properties containing
1,460 units, one vacant land parcel and retail space at a consolidated property
to unaffiliated parties. The Company expects a combined disposition price of
approximately $65.6 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.

7.     INVESTMENTS IN UNCONSOLIDATED ENTITIES

       The Company has entered into two separate joint venture agreements with
third party development companies whereby the Company contributes 25% to 30% of
the development cost to the joint venture in return for preferential returns of
9.0% per annum. The basis of the Company's equity investments in these two joint
ventures was $298.5 million and $235.9 million as of September 30, 2001 and
December 31, 2000, respectively.

       The Company also has various other investments in unconsolidated entities
with ownership interests ranging from 1.5% to 50.0%. The basis of these equity
investments was $53.4 million and $80.6 million as of September 30, 2001 and
December 31, 2000, respectively.

       These investments are accounted for under the equity method of
accounting.

8.     DEPOSITS - RESTRICTED

       Deposits-restricted as of September 30, 2001 primarily included the

    BE ANTI-DILUTIVE.

    ON OCTOBER 11, 2001, THE COMPANY EFFECTED A TWO-FOR-ONE SPLIT OF ITS
    COMMON SHARES TO SHAREHOLDERS OF RECORD AS OF SEPTEMBER 21, 2001. ALL PER
    SHARE DATA AND NUMBERS OF COMMON SHARES HAVE BEEN RETROACTIVELY ADJUSTED
    TO REFLECT THE COMMON SHARE SPLIT.

13.    Commitments and Contingencies

       The Company, as an owner of real estate, is subject to various
environmental laws of Federal and local governments. Compliance by the Company
with existing laws has not had a material adverse effect on the Company's
financial condition and results of operations. However, the Company 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 Company does not believe there is any litigation threatened against
the Company 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 Company.

       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 Company funded a net total of $109.5 million during the
nine months ended September 30, 2001. During the fourth quarter of 2001, the
Company expects to fund approximately $23.5 million in connection with these
Properties. In

                                       16
<Page>

connection with one joint venture agreement, the Company has an obligation to
fund up to an additional $6.5 million to guarantee third party construction
financing. As of September 30, 2001, the Company has 19 projects under
development with estimated completion dates ranging from December 31, 2001
through June 30, 2003. At any time following the completion of construction of
any development property, the Company's joint venture partners have the right to
cause the Company to acquire their respective interests in the completed
projects at a mutually agreeable price. If the Company and the joint venture
partner are unable to agree on a price, appraisals will be obtained by both
parties. If the appraised values vary by more than 10%, both the Company 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 Company provided a credit
enhancement with respect to certain tax-exempt bonds issued to finance certain
public improvements at a multifamily development project. As of September 30,
2001, this enhancement was still in effect at a commitment amount of $12.7
million.

14.    ASSET IMPAIRMENT

       As of September 30, 2001, the Company recorded $60.0 million of asset
impairment charges related to its furniture rental business. These charges were
the result of review of the existing intangible and tangible assets reflected on
the consolidated balance sheet as of September 30, 2001. The Company reviewed
the current net book value taking into consideration existing business and
economic conditions as well as projected operating cash flows. The impairment
loss is reflected on the income statement in total expenses and includes the
write-down of the following assets: a) goodwill of approximately $26.0 million;
b) rental furniture, net of approximately $28.6 million; c) property and
equipment, net of approximately $4.5 million; and d) other assets of
approximately $0.9 million.

       For the nine months ended September 30, 2001, the Company recorded
approximately $8.0 million of asset impairment charges related to its technology
investments. These charges were the result of review of the existing investments
reflected on the consolidated balance sheet. The Company reviewed the current
relative value of each investment based on existing economic conditions and
current events. These impairment losses are reflected on the income statement in
total expenses and includes the write-down of assets classified as investments
in unconsolidated entities.

15.    REPORTABLE SEGMENTS

       Operating segments are defined as components of an enterprise about which
separate financial information is available that is evaluated regularly by
senior management. Senior management decides how resources are allocated and
assesses performance on a monthly basis.

       The Company'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. Senior
management evaluates the performance of each of our apartment communities on an
individual basis, however, each of our apartment communities has similar
economic characteristics, residents and products and services so they have been
aggregated into one reportable segment. The Company's rental real estate segment
comprises approximately 95.2% and 96.9% of total revenues for the nine months
ended September 30, 2001 and 2000, respectively, and approximately 95.8% and
94.3% of total revenues for the quarters ended September 30, 2001 and 2000,
respectively.

       The primary financial measure for the Company's rental real estate
segment is net operating income ("NOI"), which represents rental income less: 1)
property and maintenance expense; 2) real estate

                                       17
<Page>

taxes and insurance expense; and 3) property management expense (all as
reflected in the accompanying statements of operations). Current year NOI is
compared to prior year NOI and current year budgeted NOI as a measure of
financial performance. NOI from our rental real estate totaled approximately
$937.1 million and $886.9 million for the nine months ended September 30,
2001 and 2000, respectively, and approximately $319.4 million and $294.8
million for the quarters ended September 30, 2001 and 2000, respectively.

       During the acquisition, development and/or disposition of real estate,
the NOI return on total capitalized costs is the primary measure of financial
performance (capitalization rate) the Company considers.

       The Company'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.

16.    SUBSEQUENT EVENTS

       Subsequent to September 30, 2001 and through November 7, 2001, the
Company:

          -    acquired one Property consisting of 296 units for approximately
               $23.7 million;
          -    disposed of five Properties consisting of 636 units for
               approximately $22.1 million;
          -    repaid $25.1 million of mortgage debt at or prior to maturity
               on five Properties; and
          -    relinquished $1.1 million of mortgage debt assumed by the
               purchaser in connection with the disposition of two Properties.

       In addition, the Company sold and/or contributed eleven wholly owned
Properties containing 3,011 units to a joint venture entity during the nine
months ended September 30, 2001. The Company sold and/or contributed 21 wholly
owned properties containing 5,211 units to two joint venture entities during the
nine months ended September 30, 2000. The Company retained a 25% interest along
with the rights to manage these joint venture Properties.

       The Company's acquisition and disposition activity has impacted overall
results of operations for the nine months and quarters ended September 30, 2001
and 2000. Significant changes in revenues and expenses have resulted primarily
from the consolidation of previously Unconsolidated Properties and the
acquisition of Globe, as well as the 2001 and the 2000 Acquired Properties,
which have been partially offset by the disposition of the 2001 and the 2000
Disposed Properties. Significant change in expense

                                       19
<Page>

has also resulted from impairment charges (furniture rental and unconsolidated
technology investments) recorded in 2001. This impact is discussed in greater
detail in the following paragraphs.

       Properties that the Company owned for all of both the nine month periods
ended September 30, 2001 and September 30, 2000 (the "Nine-Month 2001 Same Store
Properties"), which represented 184,391 units, and Properties that the Company
owned for all of both the quarters ended September 30, 2001 and September 30,
2000 (the "Third-Quarter 2001 Same Store Properties"), which represented 185,759
units, also impacted the Company's results of operations. Both the Nine-Month
2001 Same Store Properties and Third-Quarter 2001 Same Store Properties are
discussed in the following paragraphs.

     COMPARISON OF NINE MONTHS ENDED SEPTEMBER 30, 2001 TO NINE MONTHS ENDED
                               SEPTEMBER 30, 2000

       For the nine months ended September 30, 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 decreased by approximately $38.6 million when compared to
the nine months ended September 30, 2000.

       Rental income from the Nine-Month 2001 Same Store Properties increased by
approximately $58.9 million to $1.3 billion, or 4.7%, 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 Company
expects to achieve rental income increases of 3.75% to 4.0% from Same Store
Properties. For 2002, the Company expects to see rental income within a range of
being slightly lower by 0.05% to slightly higher by as much as 1.0%. These
estimated increases are subject to certain risks and uncertainties including,
but not limited to, maintaining an overall average occupancy rate of 93.5% to
94.0%.

       Property operating expenses from the Nine-Month 2001 Same Store
Properties, which include property and maintenance, real estate taxes and
insurance and an allocation of property management expenses, increased
approximately $20.5 million or 4.5%. The increase in "same store" expenses is
primarily attributable to a $4.8 million, or 6.5%, increase in utilities and a
$8.3 million, or 7.3% increase in payroll costs. For the remainder of 2001, the
Company expects to maintain expense growth at no more than 3.75% to 4.0% for the
Same Store Properties. For 2002, the Company expects to maintain expense growth
between a range of 1.5% to 2.25%.

       Rental income from properties other than Nine-Month 2001 Same Store
Properties increased by approximately $43.9 million primarily as a result of
revenue from the Company's corporate housing business and the acquisition of
Properties during 2001, including the consolidation of previously Unconsolidated
Properties.

       Interest income-investment in mortgage notes increased by approximately
$0.5 million as a result of receiving deferred interest income on certain of the
mortgage notes. The Company anticipates no additional interest income will be
recognized on these mortgage notes in future quarters as the Company now
consolidates the results related to these previously Unconsolidated Properties.

       Interest and other income decreased by approximately $0.8 million,
primarily as a result of lower balances and related interest rates being earned
on these investments.

       Property management expenses included off-site expenses associated with
the self-management of the Company's Properties. These expenses increased by
approximately $0.1 million. The Company continues to acquire properties in major
metropolitan areas and dispose of assets in smaller multi-family rental markets
where the Company does not have a significant management presence. As a result,
the Company is able to achieve economies of scale by not increasing off-site
management expenses as it

                                       20
<Page>

acquires additional properties.

       Fee and asset management revenues and fee and asset management expenses
increased as a result of the Company continuing to manage Properties that were
sold and/or contributed to various unconsolidated joint venture entities. As of
September 30, 2001, the Company managed 15,948 units for third parties and the
unconsolidated 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 and property and equipment
directly related to the furniture business.

       The Company recorded impairment charges totaling approximately $68.0
million, of which $60.0 million is related to the furniture rental business and
approximately $8.0 million is related to certain investments in technology
entities. See Footnote 14 in the Notes to the Consolidated Financial Statements
for further discussion.

       Interest expense, including amortization of deferred financing costs,
increased approximately $2.3 million. The effective interest cost on all of the
Company's indebtedness for the nine months ended September 30, 2001 was 6.99% as
compared to 7.25% for the nine months ended September 30, 2000. For the
remainder of 2001, the Company expects its overall interest costs to decrease
slightly due to lower variable interest rates. In connection with the scheduled
maturity of $150 million of indebtedness due in November 2001, the Company
anticipates to initially borrow under its line of credit to repay this
indebtedness. The Company also expects to replace this indebtedness in the first
quarter of 2002 for a similar amount and to incur interest costs approximating
6.5% to 7.0% per annum.

       General and administrative expenses, which include corporate operating
expenses, increased approximately $4.3 million between the periods under
comparison. This increase was primarily due to the addition of corporate
personnel and higher overall compensation expenses including a current year
expense associated with the vesting of restricted shares/awards to key employees
in the past three years.

       Net gain on sales of real estate decreased approximately $64.9 million
between the periods under comparison. This decrease is primarily the result of a
fewer number of units sold during the nine months ended September 30, 2001
(9,252 units including the joint venture Properties) as compared to the nine
months ended September 30, 2000 (12,565 units including the joint venture
Properties). In addition, the Company sold older and more fully depreciated
Properties during the nine months ended September 30, 2000 as compared to the
nine months ended September 30, 2001.

    COMPARISON OF QUARTER ENDED SEPTEMBER 30, 2001 TO QUARTER ENDED SEPTEMBER
                                    30, 2000

       For the quarter ended September 30, 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 decreased by approximately $59.8 million when compared to
the quarter ended September 30, 2000.

       Rental income from the Third-Quarter 2001 Same Store Properties increased
by approximately $14.8 million to $444.6 million or 3.4% 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
Company expects to achieve rental income increases of 3.75% to 4.0% from Same
Store Properties. For 2002, the Company expects to see rental income within a
range of being slightly lower by 0.05% to slightly higher by as much as 1.0%.
These estimated increases are subject to certain risks and uncertainties
including, but not limited to, maintaining an overall average occupancy rate of
93.5% to 94.0%.

                                       21
<Page>

       Property operating expenses from the Third-Quarter 2001 Same Store
Properties, which include property and maintenance, real estate taxes and
insurance and an allocation of property management expenses, increased
approximately $4.6 million or 2.9%. The increase in "same store" expenses is
primarily attributable to a $1.3 million, or 3.4%, increase in real estate taxes
and a $2.4 million, or 6.0% increase in payroll costs. For the remainder of
2001, the Company expects to maintain expense growth at no more than 3.75% to
4.0% for the Same Store Properties. For 2002, the Company expects to maintain
expense growth between a range of 1.5% to 2.25%.

       Rental income from properties other than Third-Quarter 2001 Same Store
Properties increased by approximately $13.1 million primarily as a result of
revenue from the Company's corporate housing business and the acquisition of
properties during the third quarter of 2001.

       Interest income-investment in mortgage notes decreased by approximately
$2.8 million as a result of the Company receiving the final payment related to
these notes prior to consolidation of these previously Unconsolidated
Properties.

       Interest and other income decreased by approximately $4.1 million,
primarily as a result of lower balances and related interest rates being earned
on the Company's short-term investment accounts.

       Property management expenses included off-site expenses associated with
the self-management of the Company's Properties. These expenses increased by
approximately $1.3 million, primarily related to higher payroll costs and
increased health costs for employees.

       Fee and asset management revenues and fee and asset management expenses
increased slightly as a result of the Company continuing to manage Properties
that were sold and/or contributed to various unconsolidated 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 and property and equipment
directly related to the furniture business.

       The Company recorded impairment charges totaling approximately $61.2
million, of which $60.0 million is related to the furniture rental business and
approximately $1.2 million is related to certain investments in technology
entities. See Footnote 14 in the Notes to the Consolidated Financial Statements
for further discussion.

       Interest expense, including amortization of deferred financing costs,
increased approximately $2.0 million. The effective interest cost on all of the
Company's indebtedness for the quarter ended September 30, 2001 was 6.82% as
compared to 7.28% for the quarter ended September 30, 2000. For the remainder of
2001, the Company expects its overall interest cost to decrease slightly due to
lower variable interest rates.

       General and administrative expenses, which include corporate operating
expenses, increased approximately $3.4 million between the periods under
comparison. This increase was primarily due to the addition of corporate
personnel and higher overall compensation expenses including a current year
expense associated with the awarding of restricted shares to key employees in
the past three years.

       Net gain on sales of real estate decreased approximately $23.8 million
between the periods under comparison. This decrease is primarily the result of
fewer units sold during the quarter ended September 30, 2001, which included
2,052 wholly owned units as compared to 3,959 wholly owned units sold in the
quarter ended September 30, 2000.

LIQUIDITY AND CAPITAL RESOURCES

       As of January 1, 2001, the Company had approximately $23.8 million of
cash and cash equivalents and the amounts available on the Company's lines of
credit were $399.5 million, of which $53.5 million was restricted. After taking
into effect the various transactions discussed in the following paragraphs and
the net cash provided by operating activities, the Company's cash and cash
equivalents balance at September 30, 2001 was approximately $110.8 million and
the amount available on the Company's line of credit was $700.0 million, of
which $60.0 million was restricted.

       Part of the Company's strategy in funding the purchase of multifamily
properties, funding its Properties in the development and/or earnout stage and
the funding of the Company'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, reinvestment of
retained cash flows or the issuance of additional equity or debt securities.
Continuing to utilize this strategy during the first nine months of 2001, the
Company:

   -   disposed of thirty-eight properties (including one Unconsolidated
       Property) and two vacant parcels of land and received net
       proceeds of $284.8 million;
   -   issued $300.0 million of unsecured debt receiving net proceeds
       of $297.4 million;
   -   sold and/or contributed eleven properties to a joint venture and
       received net proceeds of $167.6 million;
   -   issued $48.5 million of three new series of Preference Interests
       and received net proceeds of $47.3 million;
   -   obtained $59.3 million in new mortgage financing; and
   -   received a $61.4 million pay-down of second and third
       mortgages on previously Unconsolidated Properties.

During the nine months ended September 30, 2001, the Company:

   -   reduced its line of credit borrowings by approximately
       $355.5 million;
   -   funded $210.5 million to redeem all of its Series A and F
       Preferred Shares;
   -   repaid approximately $315.3 million of mortgages due at or
       prior to maturity and/or at the disposition date of respective
       properties;
   -   funded a net of $109.5 million related to the development,
       earnout and joint venture agreements; and
   -   acquired eleven properties and vacant land for $288.9 million
       ($45.9 million of mortgage assumptions and $243.0 million
       of cash).

Subsequent to September 30, 2001 and through November 7, 2001, the Company:

   -   acquired one Property consisting of 296 units for approximately
       $23.7 million;
   -   disposed of five Properties consisting of 636 units for
       approximately $22.1 million;
   -   repaid $25.1 million of mortgage debt at or prior to maturity on
       five Properties; and
   -   relinquished $1.1 million in mortgage debt assumed by the
       purchaser in connection with the disposition of two Properties.

       During the fourth quarter of 2001, the Company expects to fund
approximately $23.5 million related to the development, earnout and joint
venture agreements. In connection with one joint venture agreement, the Company
has an obligation to fund up to an additional $6.5 million to guarantee third
party construction financing. As of September 30, 2001, the Company has 19
projects under development with estimated completion dates ranging from December
31, 2001 through June 30, 2003. At any time following the completion of
construction of any development property, the Company's joint venture partners
have the right to cause the Company to acquire their respective interests in the
completed projects at a mutually agreeable price. If the Company and the joint
venture partner are unable to agree on a price, appraisals will be obtained by
both parties. If the appraised values vary by more than 10%, both the Company
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 nine months ended September 30, 2001, the Company's total
improvements to real estate approximated $108.3 million. Replacements, which
includes new carpeting, appliances, mechanical equipment, fixtures, vinyl floors
and blinds inside the unit approximated $42.8 million, or $210 per unit.
Building improvements for the 1999, 2000 and 2001 Acquired Properties
approximated $19.4 million, or $375 per unit. Building improvements for all of
the Company's pre-1999 Acquired Properties approximated $38.9 million or $257
per unit. In addition, approximately $3.6 million was spent on six specific
assets related to major renovations and repositioning of these assets. Also
included in total improvements to real estate was approximately $3.6 million on
commercial/other assets and Partially Owned Properties. 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
are estimated to be approximately $25.0 million.

       During the nine months ended September 30, 2001, the Company's total
non-real estate capital additions, such as computer software, computer
equipment, and furniture and fixtures and leasehold improvements to the
Company's property management offices and its corporate offices, was
approximately $5.2 million. Such additions to non-real estate property were
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 $0.9 million.

       The Company, 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 nine months ended
September 30, 2001, total additions to rental furniture approximated $17.8
million and property and equipment approximated $2.2 million. Total additions to
rental furniture and property and equipment budgeted for the remainder of 2001
are estimated to be approximately $1.0 million.

       Minority Interests as of September 30, 2001 increased by $22.1 million
when compared to December 31, 2000. The primary factors that impacted this
account during the quarter were:

                                       24
<Page>

   -   distributions  declared to Minority  Interests,  which
       amounted to $30.1 million for the nine months ended  September 30, 2001
       (excluding preference unit/interest distributions);
   -   the allocation of income from operations in the amount of $22.7 million;
   -   the allocation of Minority Interests from Partially Owned Properties
       in the amount of $1.5 million;
   -   the conversion of OP Units into Common Shares; and
   -   the issuance of Common Shares, OP Units and Preference Interests
       during the nine months ended September 30, 2001.

       Total distributions paid in October 2001 amounted to approximately $146.4
million, which included distributions declared for the quarter ended September
30, 2001.

       The Company 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 Company considers its cash provided by
operating activities to be adequate to meet operating requirements and payments
of distributions. The Company 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 and proceeds received from the
disposition of certain Properties. In addition, the Company has certain
uncollateralized Properties available to secure additional mortgage borrowings
in the event that the public capital markets are unavailable to the Company or
the cost of alternative sources of capital to the Company is too high.

       The Company 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 November 9, 2001, $35.0 million was outstanding under this
facility.

       In connection with the Globe acquisition, the Company assumed a revolving
credit facility with Fifth Third Bank with potential borrowings of up to $55.0
million. This credit facility was terminated on May 31, 2001.

       In connection with the Wellsford Merger, the Company provided a credit
enhancement with respect to certain tax-exempt bonds issued to finance certain
public improvements at a multifamily development project. As of November 7,
2001, this enhancement was still in effect at a commitment amount of $12.7
million.
