                    Notes to Condensed Financial Statements

                            March 31, 1999 and 1998
                                  (Unaudited)


(1) General

  In July 1998, Security Capital Pacific Trust consummated a merger with
Security Capital Atlantic Incorporated (the "Atlantic Merger") to form the
company now known as Archstone Communities Trust.  The transaction was accounted
for as a purchase and therefore, the financial information as of and for the
periods prior to the merger date reflects only the balances and activity of
Security Capital Pacific Trust.

  The condensed financial statements of Archstone are unaudited and certain
information and footnote disclosures normally included in financial statements
have been omitted.  While management believes that the disclosures presented are
adequate, these interim financial statements should be read in conjunction with
the financial statements and notes included in Archstone's 1998 Annual Report on
Form 10-K ("1998 Form 10-K").

  In the opinion of management, the accompanying unaudited financial statements
contain all adjustments necessary for a fair presentation of Archstone's
financial statements for the interim periods presented.  The results of
operations for the three month periods ended March 31, 1999 and 1998 are not
necessarily indicative of the results to be expected for the entire year.

  The accounts of Archstone and its controlled subsidiaries are consolidated in
the accompanying condensed financial statements.  All significant intercompany
accounts and transactions have been eliminated in consolidation.  Archstone uses
the equity method to account for its investments when it does not control, but
has the ability to exercise significant influence over, the operating and
financial policies of the investee.  For an investee accounted for under the
equity method, Archstone's share of net earnings or losses of the investee is
reflected in income as earned and dividends are credited against the investment
as received.

  The preparation of these financial statements in conformity with generally
accepted accounting principles ("GAAP") requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent liabilities at the dates of the financial statements
and the reported amounts of revenues and expenses during the reporting periods.
Actual amounts realized or paid could differ from those estimates.

 Reclassifications

  Certain 1998 amounts have been reclassified to conform to the 1999
presentation.

 Administrative Services Agreement

  Archstone paid $1.8 million and $1.2 million to an affiliate for services
purchased under an administrative services agreement during the three months
ended March 31, 1999 and 1998, respectively.

(2)  "In Planning" is defined as parcels of land owned or Under Control upon
     which construction of apartments is expected to commence within 36 months.
     "Under Control" means Archstone has an exclusive right (through contingent
     contract or letter of intent) during a contractually agreed-upon time
     period to acquire land for future development of apartment communities at a
     fixed price, subject to approval of contingencies during the due diligence
     process, but does not currently own the land.  There can be no assurance
     that such land will be acquired.
(3)  Archstone's investment as of March 31, 1999 and December 31, 1998 for
     developments Under Control was $5.7 million and $4.8 million, respectively,
     and is reflected in the ''Other assets'' caption of Archstone's Balance
     Sheets.

     At March 31, 1999, Archstone had unfunded apartment construction,
redevelopment and operating community acquisition commitments aggregating
approximately $330.8 million.

     Archstone had 13 apartment communities and certain other real estate assets
under contract for sale with an aggregate carrying value of $133.2 million as of
March 31, 1999. Each property's carrying value is less than or equal to its
estimated fair market value, net of estimated costs to sell. The property-level
earnings, after mortgage interest and depreciation, from communities held for
disposition at March 31, 1999 were $878,000 and $739,000 for the three months
ended March 31, 1999 and 1998, respectively.

     During the three months ended March 31, 1999, Archstone concluded that the
full recovery of certain real estate assets was doubtful. As a result, a
provision for possible loss of $2.0 million was recorded to reduce these assets
to their estimated net realizable value.


(3)  Borrowings

  Unsecured Credit Facilities

     Archstone has a $750 million unsecured revolving line of credit provided by
a group of financial institutions led by Chase Bank of Texas, National
Association ("Chase"). The $750 million line of credit matures in July 2001, at
which time it may be converted into a two-year term loan at Archstone's option.
The line of credit bears interest at the greater of prime or the federal funds
rate plus 0.50%, or at Archstone's option, LIBOR (4.96% at March 31, 1999) plus
0.65%. Under a competitive bid option contained in the credit agreement,
Archstone may be able to borrow at a lower interest rate spread over LIBOR,
depending on market conditions, on up to $375 million of borrowings. Under the
agreement, Archstone pays a facility fee, which is equal to 0.15% of the
commitment.

     On April 13, 1999, Archstone entered into an interest rate swap agreement
with a notional amount of $100 million, relating to a portion of the outstanding
balance on its $750 million unsecured line of credit. The $100 million swap
effectively provides for a fixed nominal interest rate of 5.05% through April
13, 2000, at which time the agreement terminates.

     Archstone's $100 million short-term, unsecured borrowing agreement with
Chase bears interest at an overnight rate that ranged from 5.62% to 6.25% during
the three months ended March 31, 1999. At March 31, 1999, there was $15.8
million outstanding under this agreement.

  General

     Archstone's debt instruments generally contain certain covenants common to
the type of facility or borrowing, including financial covenants establishing
minimum debt service coverage ratios and maximum leverage ratios. Archstone was

     For the three months ended March 31, 1999 and 1998, the total interest paid
in cash on all outstanding debt was $41.3 million and $24.7 million,
respectively. Archstone capitalizes interest incurred during the construction
period as part of the cost of apartment communities under development. Interest
capitalized during the three months ended March 31, 1999 and 1998 was $8.8
million and $5.2 million, respectively.

     Amortization of loan costs included in interest expense for the three

Common Share of beneficial interest, par value $1.00 per share ("Common Share")
on February 26, 1999. On April 21, 1999, the Board declared the second quarter

             Notes to Condensed Financial Statements - (Concluded)


     During the three months ended March 31, 1999, approximately 176,900 of
Series A Convertible Preferred Shares were converted, at the option of the
holders, into approximately 238,300 Common Shares. This activity is included in
"Other, net" in the accompanying Condensed Statement of Shareholders' Equity.

     At March 31, 1999, Security Capital Group Incorporated, Archstone's largest
shareholder, owned approximately 39.0% of Archstone's Common Shares outstanding.

(6)  Segment Data

     During 1998, Archstone adopted Statement of Financial Accounting Standards
No. 131, Disclosures about Segments of an Enterprise and Related Information,
which established standards for the way that public business enterprises report
information about operating segments in audited financial statements, as well as
related disclosures about products and services, geographic areas and major
customers.

     Archstone defines each of its apartment communities as individual operating
segments. Management has determined that all of its apartment communities have
similar economic characteristics and also meet the other criteria which permit
the apartment communities to be aggregated into one reportable segment.
Archstone relies primarily on Net Operating Income, defined as rental revenues
less property operating expenses and real estate taxes, ("NOI") generated from
its apartment communities for purposes of making decisions about allocating
resources and assessing segment performance.

     Following are reconciliations of the reportable segment's: (i) revenues to
Archstone's consolidated revenues and (ii) NOI to Archstone's consolidated
earnings from operations (in thousands):

                    INDEPENDENT ACCOUNTANTS' REVIEW REPORT



The Board of Trustees and Shareholders
of Archstone Communities Trust:



     We have reviewed the accompanying condensed balance sheet of Archstone
Communities Trust as of March 31, 1999, the related condensed statements of
earnings for the three month periods ended March 31, 1999 and 1998, the
condensed statement of shareholders' equity for the three month period ended
March 31, 1999 and the condensed statements of cash flows for the three month
periods ended March 31, 1999 and 1998. These condensed financial statements are
the responsibility of the Trust's management.

     We conducted our review in accordance with standards established by the
American Institute of Certified Public Accountants. A review of interim
financial information consists principally of applying analytical procedures to
financial data and making inquiries of persons responsible for financial and
accounting matters. It is substantially less in scope than an audit conducted in
accordance with generally accepted auditing standards, the objective of which is
the expression of an opinion regarding the financial statements taken as a
whole. Accordingly, we do not express such an opinion.

     Based on our review, we are not aware of any material modifications that
should be made to the condensed financial statements referred to above for them
to be in conformity with generally accepted accounting principles.

     We have previously audited, in accordance with generally accepted auditing
standards, the balance sheet of Archstone Communities Trust as of December 31,
1998, and the related statements of earnings, shareholders' equity, and cash
flows for the year then ended (not presented herein); and in our report dated
January 22, 1999, except as to Note 15, which is as of March 5, 1999, we
expressed an unqualified opinion on those financial statements. In our opinion,
the information set forth in the accompanying condensed balance sheet as of
December 31, 1998 is fairly stated, in all material respects, in relation to the
balance sheet from which it has been derived.

Results of Operations

  Three Months Ended March 31, 1999 Compared to March 31, 1998

     Earnings from operations increased $10.0 million during the three months
ended March 31, 1999 over the same period in 1998. This increase was offset by:
(i) a $10.1 million decrease in net gains on dispositions of depreciated real
estate, (ii) a $1.1 million extraordinary item related to the early
extinguishment of certain mortgage debt, and (iii) a $1.0 million increase in
Preferred Share dividends, to produce a net decrease in net earnings
attributable to Common Shares of $2.2 million.

 Apartment Community Operations

     At March 31, 1999, investments in apartment communities comprised over 99%
of Archstone's total real estate portfolio, based on total expected investment.
The following table summarizes the NOI generated from Archstone's apartment
communities for each period (in thousands, except for percentages):

</TABLE>

     The increases in rental revenues, property operating expenses and real
estate taxes are due primarily to a net increase of 95 operating apartment
communities from March 31, 1998 to March 31, 1999 (including those acquired in
the Atlantic Merger) and growth in NOI from operating apartment communities.
Increased operating efficiencies and Archstone's commitment to customer-focused
operations have contributed to the improvement in operating margins.

     Approximately 84.2% and 85.2% of Archstone's operating portfolio was
classified as stabilized (meaning that development/redevelopment, new marketing
programs and possibly new management have been completed for a sufficient period
of time to achieve 93% occupancy at market rents) as of March 31, 1999 and 1998,
respectively. The full impact on NOI from Archstone's development activities
and, to a lesser extent, acquisition activities, is not reflected until after
the communities are stabilized. As buildings are completed and leased, NOI
increases until the overall community is producing a stabilized yield, which is
generally achieved 18 to 24 months after construction commences. Management
believes Archstone's operating results continue to demonstrate that its
development activities contribute positively to long-term operating performance.

                                       14
<PAGE>
 
     Management believes that future property operating results will be
positively impacted by Archstone's customer focused operating initiatives and
its recently implemented national branding strategy, which was designed to
increase customer loyalty and reduce turnover rates through quality service
guarantees and other similar initiatives.

  Other Income

     Other income is primarily influenced by interest income on convertible
mortgage notes receivable. During the three months ended March 31, 1999 and
1998, Archstone recorded $5.8 million and $5.5 million in interest income,
respectively ($5.3 million and $5.1 million, respectively for purposes of
calculating funds from operations), from these notes. The increase is a direct
result of higher average outstanding note balances during the three months ended
March 31, 1999 as compared to the three months ended March 31, 1998. See "-
Liquidity and Capital Resources-Funding Sources" for a discussion of the future
monetization of these notes.

  Depreciation Expense

     The increase in depreciation expense resulted primarily from the increase
in the number and cost basis of operating communities, including those acquired
in the Atlantic Merger, partially offset by dispositions.

  Interest Expense

     The increase in interest expense is primarily attributable to higher
outstanding debt balances associated with the financing of Archstone's
investment activities. These higher borrowing costs were partially offset by the
capitalization of interest on apartment development activities. Interest expense
will be higher in 1999 as compared to 1998 primarily due to the debt assumed in
the Atlantic Merger and the debt issued in 1998 and 1999 to fund Archstone's
investment activities.

  General and Administrative Expenses

     The overall increase in general and administrative expenses relates
primarily to the incremental costs associated with operating the company after
the Atlantic Merger.

  Provision for Possible Loss on Investments

     During the three months ended March 31, 1999, management concluded that the
full recovery of certain real estate investments was doubtful. As a result, a
provision for possible loss of $2.0 million, which is included in "Other" in the
accompanying Condensed Statements of Earnings, was recorded to reduce these
assets to their estimated net realizable value.

  Gains on Dispositions of Depreciated Real Estate

     During the three months ended March 31, 1999, Archstone disposed of nine
apartment communities and certain other real estate assets, representing gross
proceeds of $113.1 million. Archstone disposed of five apartment communities and
certain other real estate assets, representing gross proceeds of $101.1 million
during the three months ended March 31, 1998. Aggregate net gains of $5.3
million and $15.5 million, were recorded for the three months ended March 31,
1999 and March 31, 1998, respectively.

     As part of its ongoing asset optimization strategy, Archstone had 13
apartment communities and certain other real estate assets under contract for
sale with an aggregate carrying value of $133.2 million as of March 31, 1999.
Subject to normal closing risks, Archstone expects to complete these and other
dispositions during 1999 and use the proceeds to fund future investment
opportunities. As part of management's long-term strategy of proactively
managing its investments, Archstone will continue to pursue favorable
opportunities to dispose of assets that do not meet its long-term investment
criteria, and use such proceeds for incremental investments in its specifically
targeted markets, including California, Washington, D.C. and Boston,
Massachusetts.

  Preferred Share Dividends

     The higher level of Preferred Share dividends is attributable to the
assumption of the Series C Preferred Shares in the Atlantic Merger and an
increase in the Series A Convertible Preferred Share dividend rate, partially
offset by conversions of Series A Convertible Preferred Shares into Common
Shares.

                                       15
<PAGE>
 
Liquidity and Capital Resources

     Archstone has a conservative financial strategy and prudently manages its
balance sheet in order to avoid liquidity issues in any given quarter or year.
Archstone believes that this approach to proactively managing its financial
position will provide a competitive advantage when many of Archstone's
competitors do not have access to capital to fund incremental investment
opportunities.

     Archstone continues to focus on community dispositions in its non-core
markets as a source of funds for incremental strategic investments in its
specifically targeted markets, including California, Washington, D.C. and
Boston, Massachusetts. In addition, as of May 10, 1999, Archstone also has a
total of $471.1 million of undrawn capacity on its existing unsecured credit
facilities to fund incremental investment opportunities. Archstone has only
$112.3 million of Long-Term Unsecured Debt and mortgages payable with final
maturities in 1999 and 2000. Furthermore, as of March 31, 1999, 79% of
Archstone's assets were unencumbered by mortgages. As a result of these factors,
Archstone believes that its financial and liquidity position are relatively
strong and the company is positioned to capitalize on investment opportunities
that may arise during the remainder of 1999.

  Operating Activities

     Net cash flow provided by operating activities increased by $17.5 million
(50.6%) for the three months ended March 31, 1999 as compared to the same period
of 1998. This increase is due primarily to the Atlantic Merger in July 1998, the
development of new apartment communities and cash flow growth from existing
apartment communities.

  Investing and Financing Activities

     During the three months ended March 31, 1999 and 1998, Archstone invested
$236.9 million and $117.6 million, respectively, in real estate investments. The
$236.9 million invested in real estate and the repurchase of $88.2 million of
Common Shares during the three months ended March 31, 1999 were financed
primarily from property dispositions, tax-deferred exchange escrow proceeds,
cash flow from operations and additional borrowings. The $117.6 million invested
in real estate during the three months ended March 31, 1998 was financed
primarily from property dispositions and borrowings under Archstone's unsecured
credit facilities. These unsecured credit facilities were partially repaid with
proceeds related to the issuance of $125 million of Long-Term Debt in March
1998.

     Other significant financing activities included: (i) the payment of $59.1
million and $36.2 million in Common and Preferred Share distributions for the
three months ended March 31, 1999 and 1998, respectively. The increases are
primarily attributable to an increase in the overall number of Common Shares
outstanding, Series C Preferred Shares assumed in the Atlantic Merger in 1998,
and an increase in the cash distributions paid per Common Share; and (ii) the
prepayment of mortgages due to community dispositions of $7.9 million and $11.1
million during the three months ended March 31, 1999 and 1998, respectively.

     Archstone's significant non-cash investing and financing activities during
the three months ended March 31, 1999 and 1998 included the assumption of
mortgage debt and the conversion of Series A Convertible Preferred Shares into
Common Shares.

  Scheduled Debt Maturities and Interest Payment Requirements

     In order to reduce refinancing risk, Archstone's long-term debt obligations
are carefully structured to create a relatively level principal maturity
schedule in an attempt to minimize the requirement for large payments due in any
single year. As of March 31, 1999, Archstone has only $35.5 million of long-term
debt payments with final maturities due during the remainder of 1999 and only
$76.8 million of final maturities during 2000.

     Archstone currently has $850 million in total borrowing capacity under its
unsecured credit facilities, with $378.9 million outstanding and an available
balance of $471.1 million at May 10, 1999. Archstone's unsecured credit
facilities, Long-Term Unsecured Debt and mortgages payable had all-in effective
interest rates of 6.3%, 7.5% and 5.9%, respectively, as of March 31, 1999.

                                       16
<PAGE>
 
  Shareholder Dividend/Distribution Requirements

     Archstone paid the first quarter 1999 distribution of $0.37 per Common
Share on February 26, 1999. On April 21, 1999 the Board declared a cash
distribution of $0.37 per Common Share, payable on May 28, 1999 to shareholders
of record on May 14, 1999. On March 31, 1999, Archstone paid quarterly dividends
of $0.4984 per Series A Convertible Preferred Share, $0.5625 per Series B
Preferred Share and $0.5391 per Series C Preferred Share.

     Based on current distribution levels (excluding the impact of anticipated
future increases in Archstone's dividend/distribution levels) and the number of
Archstone shares outstanding as of March 31, 1999, the company anticipates that
it will pay the following dividends/distributions during the next 12 months (in
thousands):

</TABLE>

     Management anticipates that all interest and distribution/dividend
requirements can be funded from operating cash flow.

     At March 31, 1999, Security Capital Group Incorporated, Archstone's largest
shareholder, owned approximately 39.0% of Archstone's Common Shares outstanding.

  Share Repurchase Program

     In February 1999, the Board authorized the repurchase of up to $100 million
of Archstone's Common Shares. Through April 16, 1999, Archstone had repurchased
4.6 million of its Common Shares at a weighted average price of $19.58 per
share, for a total purchase price of $89.9 million. Apartment community
disposition proceeds were used to reduce Archstone's unsecured credit
facilities, providing the capacity to fund the share purchases.

  Planned Investments

     Following is a summary of unfunded planned investments as of March 31, 1999
(dollar amounts in thousands). The amounts labeled "Discretionary" represent
future investments that Archstone plans to make, although there is not a
contractual commitment to do so. The amounts labeled "Committed" represent the
approximate amount that Archstone is contractually committed to fund. For
community acquisitions under contract, only the transactions with non-refundable
earnest money are reflected as "Committed".

     Archstone anticipates completion of most of the communities that are
currently under construction and the planned operating community improvements in
the remainder of 1999 and 2000 and expects to start construction on
approximately $200 million, based on total expected investment, of communities
that are currently in planning, during the remainder of 1999. Acquisitions of
operating communities that are currently under contract or letter of intent are
expected to be funded with disposition proceeds during the remainder of 1999. No
assurances can be given that communities Archstone does not currently own will
be acquired or that planned developments will actually occur. In addition,
actual costs incurred could be greater or less than Archstone's current
estimates.

  Funding Sources

     Archstone expects to finance its investment and operating needs, including
those outlined above, primarily with cash flow from operating activities,
borrowings under its unsecured credit facilities and disposition proceeds, prior
to arranging long-term financing. Archstone routinely uses its unsecured credit
facilities to facilitate an efficient response to market opportunities while
minimizing the amount of cash invested in short-term investments at lower
yields. The unsecured credit facilities had $471.1 million in available undrawn
capacity as of May 10, 1999.

     Other sources of future liquidity and financial flexibility include:

     (i)  Archstone currently has $827.2 million in shelf registered securities
          which can be issued in the form of Long-Term Unsecured Debt, preferred
          shares or Common Shares on an as-needed basis, subject to its ability
          to effect offerings on satisfactory terms.

     (ii) Archstone continues to explore the potential monetization of its
          $221.3 million (face amount at March 31, 1999) investment in its
          convertible mortgage notes receivable. Management views the future
          sale or other monetization of these assets as a potential source of
          funds, although there is presently no established market for these
          securities.

  Other Contingencies and Hedging Activities

     Archstone is a party to various claims and routine litigation arising in
the ordinary course of business. Archstone does not believe that the results of
any such claims and litigation, individually or in aggregate, will have a
material adverse effect on its business, financial position or results of
operations.

     Archstone has only limited involvement with derivative financial
instruments and does not use them for trading purposes. Archstone occasionally
utilizes derivative financial instruments as hedges in anticipation of future
debt transactions to manage well-defined interest rate risk or to minimize
exposure to variable rate debt.

     On April 13, 1999, Archstone entered into an interest rate swap agreement
with a notional amount of $100 million, relating to a portion of the outstanding
balance on its $750 million unsecured line of credit. The $100 million swap
effectively provides for a fixed interest rate of 5.05% through April 13, 2000,
at which time the agreement terminates.

     In January 1999, Archstone entered into two interest rate swap agreements
with notional amounts aggregating $55.0 million, relating to Long-Term Unsecured
Debt. The $55.0 million of notes, which were originally issued at a floating
weighted average effective interest rate of 7.34%, were effectively converted to
a fixed weighted average interest rate of 7.12% through maturity. In January
1999, Archstone also entered into an interest rate swap on $150 million of
Fannie Mae secured debt, which effectively provides for a fixed interest rate of
6.3% until maturity in 2006.

     In connection with the closing of the $268.5 million Fannie Mae secured
debt agreement in December 1998, Archstone entered into an interest rate cap
agreement on December 30, 1998 with a notional amount aggregating $118.5
million, which capped this portion of the debt at an effective interest rate of
6.9% through December 2002. The actual floating effective interest rate on the
$118.5 million was 5.9% at March 31, 1999.

     At March 31, 1999, Archstone had a net unrealized gain of $5.1 million on
its outstanding derivative financial instruments.

  Year 2000 Issue

     Archstone uses a significant number of information technology ("IT") and
non-IT computer systems in its operations. The IT systems include accounting and
property management systems, its desktop and communications systems and its
other corporate systems. The non-IT systems include embedded microprocessors
that control building systems such as lighting, security, fire, elevators,
heating, ventilating and air conditioning systems.

     In 1997, Archstone began to address the year 2000 issue (that is, the fact
that some systems might fail or produce inaccurate results using dates in or
around the year 2000). Most of Archstone's key IT systems, including its
property management software, have recently been replaced or upgraded and
management plans to replace or upgrade the remaining key IT systems during the
third quarter of 1999. Management believes, based on statements by vendors and
on its own testing, that all of the replacements and upgrades for mission-
critical IT systems are year 2000 ready. Management is also continuing to
replace or upgrade other non-critical IT systems with year 2000 ready systems to
the extent that it is cost-effective to do so.

     Archstone is working with its vendors to confirm that the non-IT systems at
its communities are year 2000 compliant and is continuing to replace critical
non-IT systems that it believes are not year 2000 compliant. Archstone expects
that its communities will be year 2000 compliant by the end of the third quarter
of 1999.

     Archstone relies on a variety of outside suppliers to provide critical
services to its communities. Of particular concern are the local utilities.
Electric utilities, for example, use numerous embedded systems in producing,
measuring, controlling and dispensing electricity. Without electricity, almost
none of the systems at any community will function. Archstone does not control
these outside suppliers and for some suppliers there may be no feasible
alternative supplier available. In management's view, the most significant
foreseeable external risk associated with the year 2000 issue is the potential
for a sustained failure of a utility or other supplier which could have a
material adverse effect on the operations of the affected community. A
widespread sustained failure of utilities or other suppliers in areas that
Archstone has a substantial presence could have a material adverse effect on
Archstone.

     Archstone has developed and will continue to refine contingency plans to
address the risk created by the year 2000 issue. These plans generally include
having community management representation available at the communities during
the century change to handle year 2000 issues as they arise and using the
methods that Archstone's community managers customarily use to address failures
by systems and suppliers.

     Archstone's historical costs for addressing the year 2000 issue are not
material and management does not anticipate that its future costs associated
with the year 2000 issue will be material. Archstone does not separately track
the internal costs incurred for year 2000 compliance issues. Such costs are
principally the related payroll of its information technology group. Although
the cost of replacing Archstone's key IT systems is substantial, the
replacements have been and are being made to improve operational efficiency and
were not accelerated due to the year 2000 issue. In the event that the
implementation of these systems is unexpectedly delayed, Archstone would be
required to make modifications and upgrades to its existing accounting systems
for financial reporting purposes. Management believes that the costs of these
modifications and upgrades would not have a material adverse impact on the
Company's financial position or results of operations. Funds expended to date to
address year 2000 issues have come from operating cash flow. Archstone has not
delayed any material projects as a result of the year 2000 issue.

     There can be no assurance that year 2000 remediation by Archstone or third
parties will be properly and timely completed and failure to do so could have a
material adverse effect on Archstone, its business and financial condition.
Archstone cannot predict the actual effects of the year 2000 issue which depends
on numerous uncertainties, many of which are outside its control, such as
whether significant third parties such as banks and utilities address year 2000
issues properly and timely and whether broad-based or systemic economic failures
may occur. Archstone will continue to monitor these issues through its year 2000
compliance program.

  Funds From Operations

     Archstone believes that funds from operations is helpful to the reader as a
measure of the performance of an equity real estate investment trust ("REIT") 
because, along with cash flow from operating, investing and financing
activities, it provides the reader with an indication of the ability of
Archstone to incur and service debt, to make capital expenditures, to make
Common Share and Preferred Share distributions and to fund other cash needs.
Funds from operations should not be considered as an alternative to net earnings
or any other GAAP measurement of performance as an indicator of Archstone's
operating performance or as an alternative to cash flow from operating,
investing or financing activities as a measure of liquidity. The funds from
operations measure presented by Archstone, while consistent with the National
Association of Real Estate Investment Trusts' definition, will not be comparable
to similarly titled measures of other REIT's that do not compute funds from
operations in a manner consistent with Archstone. Funds from operations is not
intended to represent cash available to shareholders. Cash distributions paid to
shareholders are summarized above in "-Shareholder Dividend/Distribution
Requirements". Funds from operations were as follows (amounts in thousands):

Item 3. Quantitative and Qualitative Disclosures About Market Risk

     Archstone is exposed to interest rate changes primarily as a result of its
unsecured credit facilities and other variable rate debt used to finance its
investment activity and maintain financial liquidity. Archstone's interest rate
risk management objective is to limit the impact of interest rate changes on
earnings and cash flows and to lower its overall borrowing costs. To achieve its
objectives, Archstone borrows primarily at fixed rates. Archstone has only
limited involvement with derivative financial instruments and does not use them
for trading purposes. Archstone occasionally utilizes derivative financial
instruments as hedges in anticipation of future debt transactions to manage 
well-defined interest rate risk or to minimize exposure to variable rate debt.

     See Archstone's 1998 Form 10-K "Item 7A. Quantitative and Qualitative
Disclosures About Market Risk" for a more complete discussion of Archstone's
interest rate sensitive assets and liabilities. As of March 31, 1999, there have
been no material changes in the fair values of assets and liabilities disclosed
in "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" in
Archstone's 1998 Form 10-K, as compared to their respective book values.
