                    NOTES TO CONDENSED FINANCIAL STATEMENTS

                            March 31, 1998 and 1997
                                  (Unaudited)

(1) General

     The condensed financial statements of SECURITY CAPITAL PACIFIC TRUST
("PTR") are unaudited and certain information and footnote disclosures normally
included in financial statements have been omitted. While management of PTR
believes that the disclosures presented are adequate, these interim financial
statements should be read in conjunction with the financial statements and notes
included in PTR's 1997 Annual Report on Form 10-K ("1997 Form 10-K").

     In the opinion of management, the accompanying unaudited financial
statements contain all adjustments necessary for a fair presentation of PTR's
financial statements for the interim periods presented. The results of
operations for the three month periods ended March 31, 1998 and 1997 are not
necessarily indicative of the results to be expected for the entire year.

     The accounts of PTR and its controlled subsidiaries are consolidated in the
accompanying condensed financial statements. All significant intercompany
accounts and transactions have been eliminated in consolidation.

     The preparation of these financial statements in conformity with generally
accepted accounting principles ("GAAP") required 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 1997 amounts have been reclassified to conform to the 1998
presentation.

  New Accounting Rules

     In March 1998, a new accounting rule was issued requiring that internal
costs incurred in connection with the acquisition of operating communities be
expensed as incurred. The new rule, which is to be applied prospectively from
the date of issuance, is not expected to have a material impact on PTR's
financial position or results of operations.

     In April 1998, new accounting rules were issued requiring that costs
associated with start-up activities, such as the opening of a new business or
division, be expensed as incurred. The new rules, which become effective January
1, 1999, are not expected to have a material impact on PTR's financial position
or results of operations.

  Per Share Data

     Following is a reconciliation of the numerator and denominator used to
compute basic net earnings per Common Share to that used to compute diluted net
earnings per Common Share, for the periods indicated (in thousands, except per
share amounts):

(2) Proposed Merger Transaction

     On April 2, 1998, PTR announced its agreement to merge with Security
Capital Atlantic Incorporated ("ATLANTIC") (NYSE: SCA), a multifamily real
estate investment trust ("REIT") currently operating primarily in the
southeastern United States. Pursuant to the merger transaction (the "Merger"),
ATLANTIC will be merged with and into PTR, which will continue its existence
under the name "Archstone Communities Trust" ("ARCHSTONE") and will be traded on
the New York Stock Exchange ("NYSE") under the symbol "ASN". In accordance with
the terms of the Merger, each outstanding ATLANTIC common share will be
converted into the right to receive one PTR common share of beneficial interest,
par value $1.00 per share ("Common Share") and each outstanding ATLANTIC Series
A preferred share will be converted into the right to receive one comparable
share of a new class of PTR Series C preferred shares. In addition, PTR will
assume all of ATLANTIC's debt and other liabilities upon consummation of the
Merger which aggregated $595.0 million as of March 31, 1998. The Merger has been
structured as a tax-free merger and will be accounted for under the purchase
method.

     The Board of Trustees (the "Board") approved the Merger based upon the
recommendation of a special committee comprised of independent PTR Trustees. The
recommendation of the special committee was based in part upon an opinion
obtained from a financial advisor regarding the fairness, from a financial point
of view, of the exchange ratio to PTR and the holders of PTR Common Shares other
than Security Capital Group Incorporated ("Security Capital"). The Merger, which
is expected to be completed by August 1998, is subject to the approval of
shareholders of both companies (a two-thirds majority of PTR's outstanding
Common Shares and a majority of ATLANTIC's outstanding common shares) and
satisfaction of certain other conditions. PTR filed a registration statement and
joint proxy statement with the Securities and Exchange Commission ("SEC") on
April 28, 1998, relating to the following matters: (i) the proposed Merger of
ATLANTIC with and into PTR; (ii) a proposal to adopt an amended and restated
declaration of trust of PTR which, among other things, would change PTR's name
to "Archstone Communities Trust" and increase the authorized shares from
150,000,000 to 250,000,000; and (iii) a proposal to increase the number of PTR
Common Shares available for award under the PTR 1997 Long-Term Incentive Plan
(the "Incentive Plan") and the PTR 1996 Share Option Plan for Outside Trustees
in an amount equal to the number of shares authorized under the corresponding
ATLANTIC option plans. The registration statement has not been declared
effective.

             NOTES TO CONDENSED FINANCIAL STATEMENTS--(Continued)

     Security Capital, which at March 31, 1998 owned 33.0% and 49.9% of the
outstanding PTR Common Shares and ATLANTIC common shares, respectively, has
agreed to vote all of its PTR Common Shares and ATLANTIC common shares in favor
of the Merger, subject to certain conditions. If the Merger is consummated,
Security Capital will own approximately 38.7% (based on March 31, 1998
information) of ARCHSTONE's common stock and will be ARCHSTONE's largest
shareholder.

     As part of the Merger, PTR distributions would be adjusted following the
close of the transaction to an annualized level of $1.42 per Common Share, an
increase of 4.4% from PTR's current annual distribution level of $1.36 per
Common Share.

(2) "In Planning" is defined as parcels of land owned or Under Control upon
    which multifamily construction is expected to commence within 36 months.
    "Under Control" means PTR 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 multifamily communities, 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) PTR's investment as of March 31, 1998 and December 31, 1997 for developments
    Under Control was $3.1 million and $3.8 million, respectively, and is
    reflected in the "Other assets" caption of PTR's balance sheets.

(4) Homestead Convertible Mortgages

     During the three month period ended March 31, 1998, PTR funded an
additional $4.0 million under its $198.8 million commitment to provide
development funding to Homestead in the form of convertible mortgage notes,
resulting in a total amount funded of $190.9 million as of March 31, 1998.
Following is a reconciliation of the Homestead convertible mortgages' components
to the amount reflected in the accompanying condensed balance sheet (in

     The Homestead convertible mortgages are convertible into Homestead common
stock on the basis of one share of Homestead common stock for every $11.50 of
principal face amount outstanding. The difference between the fair value of the
Homestead convertible mortgages (assuming conversion), as calculated based upon
the trading price of Homestead's common stock on the American Stock Exchange at
March 31, 1998 ($15.125), and the amortized cost of the Homestead convertible
mortgages, is reflected as an additional component of the Homestead convertible
mortgages balance and as an unrealized holding gain in shareholders' equity. The
unrealized holding gain aggregated $86.2 million as of March 31, 1998.

(5)  Borrowings

  Credit Facilities

     PTR has a $350 million unsecured revolving line of credit with a group of
financial institutions led by Chase Bank of Texas, National Association
("Chase") (collectively the "Lenders"). The line matures in August 1999 and may
be extended annually for an additional year with the approval of the Lenders.
The line of credit bears interest at the greater of prime (8.5% at March 31,
1998) or the federal funds rate plus 0.50%, or at PTR's option, LIBOR (5.6875%
at March 31, 1998) plus 0.75%. The spread over LIBOR can vary from LIBOR plus
0.50% to LIBOR plus 1.50% based upon the rating of PTR's long-term unsecured
senior notes ("Long-Term Debt"). Additionally, there is a commitment fee on the
average unfunded line of credit balance. The commitment fee was $50,000 and
$75,000 for the three months ended March 31, 1998 and 1997, respectively.

     A summary of PTR's line of credit borrowings is as follows (dollars in
thousands):

</TABLE>

     On September 9, 1996, PTR entered into a short-term, unsecured, borrowing
agreement with Chase. The loan matures March 19, 1999 and bears interest at an
overnight rate which ranged from 6.00% to 7.13% during the three months ended
March 31, 1998. At March 31, 1998, there was $13.2 million outstanding under
this agreement.

Long-Term Debt

     PTR has issued Long-Term Debt which bears interest at fixed rates, payable
semi-annually, including $125 million of 7.20% Notes (the "7.20% Notes") issued
on March 6, 1998 which proceeds were used to pay down balances on PTR's credit
facilities. The 7.20% Notes pay interest semi-annually on March 1 and September
1 of each year through March 1, 2013. Annual principal installments of $25
million commence on March 1, 2009.

     The following table summarizes the Long-Term Debt as of March 31, 1998:

  General

     PTR'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. PTR was in
compliance with all debt covenants at March 31, 1998.

     Interest paid on all borrowings for the three months ended March 31, 1998
was $19.5 million, net of $5.2 million of interest capitalized during
construction. Interest paid on all borrowings for the three months ended March
31, 1997 was $18.9 million, net of $4.4 million of interest capitalized during
construction.

     Amortization of loan costs included in interest expense for the three
months ended March 31, 1998 and 1997 was $859,000 and $729,000, respectively.

             NOTES TO CONDENSED FINANCIAL STATEMENTS -- (Concluded)
                                        

(6) Cash Distributions

     PTR paid the first quarter 1998 distribution of $0.34 per Common Share on
February 25, 1998.  On April 29, 1998, the Board declared a cash distribution of
$0.34 per Common Share, payable on May 28, 1998, to shareholders of record on
May 14, 1998.  On March 31, 1998, PTR paid quarterly dividends of $0.4579 per
PTR Series A cumulative convertible preferred shares of beneficial interest (the
"Series A Preferred Shares") and $0.5625 per Series B cumulative redeemable
preferred shares of beneficial interest (the "Series B Preferred Shares")
(collectively the "Preferred Shares").

(7) Shareholders' Equity

     On December 15, 1997, PTR filed a $400 million shelf registration with the
SEC to supplement an existing shelf registration with a balance of $170.9
million.  As a result of this filing, PTR can issue securities in the form of
Long-Term Debt, Common Shares and preferred shares on an as-needed basis,
subject to PTR's ability to effect offerings on satisfactory terms.

     On April 23, 1998, PTR sold 2,049,587 Common Shares at $22.6875 per share
in an underwritten public offering.  The net proceeds of $44.0 million (net of
underwriting discount and offering costs) were used to repay borrowings under
PTR's credit facilities.

     After giving effect to the April 23, 1998 Common Share offering and the
$125 million in Long-Term Debt issued March 6, 1998, PTR has approximately
$399.4 million in shelf-registered securities available for issuance.

The Board of Trustees and Shareholders
SECURITY CAPITAL PACIFIC TRUST:



     We have reviewed the accompanying condensed balance sheet of SECURITY
CAPITAL PACIFIC TRUST as of March 31, 1998, the related condensed statements of
earnings and cash flows for the three month periods ended March 31, 1998 and
1997, and the statement of shareholders' equity for the three month period ended
March 31, 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 SECURITY CAPITAL PACIFIC TRUST as of December
31, 1997, 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 31, 1998, except as to Note 13, which is as of March 6, 1998, 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, 1997 is fairly stated, in all material respects, in relation to the
balance sheet from which it has been derived.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

     The following information should be read in conjunction with PTR's 1997
Form 10-K as well as the financial statements and notes included in Item 1 of
this report.  See PTR's 1997 Form 10-K for a discussion of various risk factors
associated with forward-looking statements made in this document.

Proposed Merger Transaction

     On April 2, 1998, PTR announced its agreement to merge with ATLANTIC (NYSE:
SCA), a multifamily REIT currently operating primarily in the southeastern
United States.  Pursuant to the Merger, ATLANTIC will be merged with and into
PTR, which will continue its existence under the name "Archstone Communities
Trust" and will be traded on the NYSE under the symbol "ASN".  In accordance
with the terms of the Merger, each outstanding ATLANTIC common share will be
converted into the right to receive one PTR Common Share and each outstanding
ATLANTIC Series A preferred share will be converted into the right to receive
one comparable share of a new class of PTR Series C preferred shares.  In
addition, PTR will assume all of ATLANTIC's debt and other liabilities upon
consummation of the Merger which aggregated $595.0 million as of March 31, 1998.
Management anticipates replacement of the existing PTR and ATLANTIC lines of
credit with a combined facility to enable ARCHSTONE to efficiently respond to
market opportunities.  The new credit facility is expected to be in place by the
Merger date.  The Merger has been structured as a tax-free merger and will be
accounted for under the purchase method.

     The Board approved the Merger based upon the recommendation of a special
committee comprised of independent PTR Trustees.  The recommendation of the
special committee was based in part upon an opinion obtained from a financial
advisor regarding the fairness, from a financial point of view, of the exchange
ratio to PTR and the holders of PTR Common Shares other than Security Capital.
The Merger, which is expected to be completed by August 1998, is subject to the
approval of shareholders of both companies (a two-thirds majority of PTR's
outstanding Common Shares and a majority of ATLANTIC's outstanding common
shares) and satisfaction of certain other conditions.  PTR filed a registration
statement and joint proxy statement with the SEC on April 28, 1998, relating to
the following matters: (i) the proposed Merger of ATLANTIC with and into PTR;
(ii) a proposal to adopt an amended and restated declaration of trust of PTR
which, among other things, would change PTR's name to "Archstone Communities
Trust" and increase the authorized shares from 150,000,000 to 250,000,000; and
(iii) a proposal to increase the number of PTR Common Shares available for award
under the Incentive Plan and the PTR 1996 Share Option Plan for Outside Trustees
in an amount equal to the number of shares authorized under the corresponding
ATLANTIC option plans.  The registration statement has not been declared
effective.

     Security Capital, which at March 31, 1998 owned 33.0% and 49.9% of the
outstanding PTR Common Shares and ATLANTIC common shares, respectively, has
agreed to vote all of its PTR Common Shares and ATLANTIC common shares in favor
of the Merger, subject to certain conditions.  If the Merger is consummated,
Security Capital will own approximately 38.7% (based on March 31, 1998
information) of ARCHSTONE's common stock and will be ARCHSTONE's largest
shareholder.

     As part of the Merger, PTR distributions would be adjusted following the
close of the transaction to an annualized level of $1.42 per Common Share, an
increase of 4.4% from PTR's current annual distribution level of $1.36 per
Common Share.

     Based upon the multifamily portfolios of PTR and ATLANTIC at March 31, 1998
and assuming consummation of the Merger, ARCHSTONE would have 307 multifamily
communities, consisting of 91,201 units in 19 states and Washington, D.C.,
including 26,161 units under construction or In Planning (including 25
communities aggregating 7,875 units that are Under Control but not owned as of
March 31, 1998).  Additionally, ARCHSTONE's total market capitalization would be
approximately $5.3 billion.

Recent Acquisitions

     In addition to its development activity, during the three month period
ended March 31, 1998, PTR completed the acquisition of three operating
multifamily communities (568 units) in Seattle, Washington and Salt Lake City,
Utah at a total expected investment of $36.2 million.

Results of Operations

Three months ended March 31, 1998 Compared to March 31, 1997

     Net earnings for the three months ended March 31, 1998 and 1997 were $44.8
million and $45.6 million, respectively, a decrease of $0.8 million (1.8%).
This decrease resulted primarily from a $9.9 million decrease in net gains on
dispositions of depreciated real estate, partially offset by increased earnings
from multifamily communities, primarily in California, the Pacific Northwest and
Salt Lake City ("West Coast Markets").  A discussion of the major components of
PTR's results of operations follows.

Property Operations

     At March 31, 1998 and 1997, multifamily investments comprised over 99% of
PTR's total real estate portfolio, based on total expected investment.  The
following table summarizes the net operating income generated from property
operations for each period (in thousands):

</TABLE>

     The increases in rental revenues and property operating expenses in each
period are primarily a result of net increases in the number of multifamily
operating units resulting from PTR's substantial acquisition and development
activity and rental rate increases.  Management has focused its investment
emphasis primarily on key West Coast Markets which are believed to have higher
growth potential, while reducing investments in certain other markets within
PTR's geography having less attractive growth prospects.  A portion of the
increase in revenues and expenses is attributable to the greater emphasis in the
West Coast Markets since these markets are generally characterized by higher per
unit rental rates and, to a lesser extent, higher per unit operating costs.  The
positive impact of PTR's investment strategy and customer-focused property
management program is reflected in an improving operating margin which has grown
from 61.8% during the three months ended March 31, 1997 to 64.5% during the
three months ended March 31, 1998.  The higher profitability during the three
months ended March 31, 1998 is partially attributable to PTR's acquisition of
SCG Realty Services, Incorporated (the "Property Manager") on September 9, 1997.
After that date, PTR directly incurred personnel and other costs related to
property management-related overhead, in lieu of paying a property

                                      19
<PAGE>
 
management fee to Security Capital, which resulted in a reduction of property
management fees during the three months ended March 31, 1998, partially offset
by a corresponding increase in rental expenses.

     PTR categorizes operating multifamily communities (which include all
completed revenue-generating communities) as either "stabilized" or "pre-
stabilized." The term "stabilized" means that renovation, repositioning, new
management and new marketing programs (or development and marketing in the case
of newly developed communities) have been completed for a sufficient period of
time (but in no event longer than 12 months, except for major rehabilitations)
to achieve 93% occupancy at market rents. Prior to being "stabilized", a
community is considered "pre-stabilized". Approximately 85.2% and 73.3% of
PTR's operating multifamily portfolio was classified as stabilized as of March
31, 1998 and 1997, respectively, based on total expected investment.
 
Analysis of Same Store Community Results

     The results of PTR's operating communities which were fully operating on
January 1, 1997 ("Same Store Communities") continue to strengthen as a result of
PTR's continued emphasis on customer-focused operations, combined with improving
economic fundamentals in its markets. Following is a summary of Same Store
Community results comparing the first quarter of 1998 to the first quarter of
1997 (dollars in thousands):

     Homestead Interest and Homestead Convertible Mortgages

     Through March 31, 1998, PTR had funded $190.9 million of its $198.8 million
Homestead funding commitment, of which $4.0 million was funded during the three
months ended March 31, 1998. This leaves a remaining commitment under the
funding agreement of approximately $7.9 million, which management anticipates
will be funded during May 1998.

     During the three months ended March 31, 1998 and 1997, PTR recorded $5.5
million and $3.2 million in interest income, respectively ($5.1 million and $2.9
million, respectively for purposes of calculating funds from operations) from
the Homestead convertible mortgages. The increase is a direct result of higher
average outstanding note balances during the three months ended March 31, 1998
as compared to the three months ended March 31, 1997. PTR deducts from net
earnings the interest income related to the amortization of the conversion
discount and warrant-related deferred revenue in calculating funds from
operations.

     Upon full funding, PTR will have funded $198.8 million in exchange for
Homestead convertible mortgages having a face amount of $221.3 million. The
Homestead convertible mortgages are convertible into Homestead common stock on
the basis of one share of Homestead common stock for every $11.50 of principal
face amount outstanding, which would result in the ownership of approximately
19.2 million shares of Homestead common stock at full funding. Under these
assumptions and using the trading price of Homestead common stock at March 31,
1998 of $15.125, PTR's ownership would result in the following incremental value
per PTR Common Share at March 31, 1998 (in thousands, except per share amounts):

  Depreciation Expense

in the number and cost basis of operating communities, partially offset by
dispositions.

</TABLE>
     The increase in interest expense on PTR's credit facilities resulted
primarily from higher average outstanding balances. Average borrowings on the
line of credit were approximately $198.4 million during the three months ended
March 31, 1998, as compared to average borrowings of approximately $151.6
million for the same period in 1997.

     Long-Term Debt interest expense increased due primarily to the issuance of
$50 million of Long-Term Debt in March 1997 and $125 million of Long-Term Debt
in March 1998.

     Mortgage interest expense increased as a result of additional weighted-
average debt outstanding due to mortgage assumptions related to community
acquisitions which were partially offset by prepayments during the three months
ended March 31, 1998 and 1997. The increase in interest costs was partially
offset by an increase in capitalized interest which was primarily attributable
to higher levels of multifamily development activity for the three months ended
March 31, 1998 as compared to the same period in 1997.

  Administrative Expenses

     PTR's overall administrative expenses (REIT management fee paid to
affiliate, general and administrative and administrative services provided by an
affiliate) of $2.8 million during the three months ended March 31, 1998 compares
favorably to the $4.9 million expensed during the three months ended March 31,
1997. PTR did not pay a REIT management fee during the three months ended March
31, 1998 due to the termination of the REIT management agreement upon the
internalization of PTR's management companies which occurred on September 9,
1997. General and administrative expenses increased primarily because PTR now
incurs actual personnel and other operating costs associated with the REIT
management function, a portion of which is capitalized, in lieu of paying a REIT
management fee to Security Capital. The increase in administrative services
provided by an affiliate is attributable to the administrative services
agreement with Security Capital which was entered into on September 9, 1997,
upon closing of the transaction described above.

  Gains on Dispositions of Depreciated Real Estate

     During the three months ended March 31, 1998, PTR disposed of five
multifamily communities and certain non-multifamily real estate assets,
representing gross proceeds of $101.1 million. As of March 31, 1998, PTR held a
portion of the 1998 disposition proceeds aggregating $15.3 million in an
interest bearing escrow account, pending acquisition of other multifamily
communities to complete a tax-deferred exchange. PTR disposed of 12 multifamily
communities and one industrial building representing gross proceeds of $142.1
million during the three months ended March 31, 1997. For federal income tax
purposes, the dispositions were generally structured as tax-deferred exchanges,
which deferred gain recognition. However, for financial reporting purposes, the
transactions qualified for profit recognition, and aggregate gains of $15.5
million and $25.3 million, were recorded for the three months ended March 31,
1998 and 1997, respectively.

                                      21
<PAGE>
 
     Two parcels of land having an aggregate carrying value of $8.7 million were
held for disposition as of March 31, 1998. Subject to normal closing risks, PTR
expects to complete the disposition of these properties and redeploy the net
proceeds through tax-deferred exchanges, into the acquisition of multifamily
communities.

Liquidity and Capital Resources

     PTR considers its liquidity and ability to generate cash from operations
and financings to be adequate and expects it to continue to be sufficient to
meet all of its cash flow requirements for the foreseeable future.

  Operating Activities

     Net cash flow provided by operating activities increased by $11.8 million
(52.0%) for the three months ended March 31, 1998 as compared to the same period
in 1997. This increase was due primarily to increased cash generated by
multifamily communities.

  Investing and Financing Activities

     During the three months ended March 31, 1998 and 1997, PTR invested cash of
$117.6 million and $177.9 million, respectively, in real estate investments
relating primarily to the significant acquisition and development activity
summarized in "-Overview" above. The $117.6 million invested in real estate and
$4.0 million in fundings of Homestead convertible mortgages during the three
months ended March 31, 1998 were financed primarily from $84.2 million of net
proceeds from property dispositions (excluding the $15.3 million held in escrow
pending tax-deferred exchanges) and borrowings under PTR's credit facilities.
These credit facilities were partially repaid from proceeds related to the
issuance of $125 million of Long-Term Debt in March 1998. The $177.9 million
invested in real estate and $16.3 million in fundings of Homestead convertible
mortgages during the three months ended March 31, 1997 were financed primarily
from $80.1 million in net proceeds from property dispositions (excluding $59.0
million held in escrow pending tax-deferred exchanges) and borrowings under
PTR's credit facilities which were partially repaid from $50 million in proceeds
related to Long-Term Debt issued in March 1997.

     Other significant financing activity included the payment of $36.2 million
and $29.7 million in Common Share distributions and Preferred Share dividends
for the three months ended March 31, 1998 and 1997, respectively. The increase
is primarily attributable to a 4.6% increase in the distributions paid per
Common Share and an increase in the overall number of Common Shares outstanding.
Preferred Share dividends decreased approximately $0.3 million during the
respective periods as a result of conversion of Series A Preferred Shares to
Common Shares which also resulted in increased Common Share distributions. PTR
prepaid mortgages due to community dispositions of $11.1 million and $9.5
million during the three months ended March 31, 1998 and 1997, respectively.

     Significant non-cash investing and financing activities included the
assumption of $8.2 million and $23.5 million of mortgage debt during the three
months ended March 31, 1998 and 1997, respectively, and the conversion of Series
A Preferred Shares to Common Shares aggregating $6.9 million and $10.4 million
during the three months ended March 31, 1998 and 1997, respectively. During the
three months ended March 31, 1998, the unrealized gain associated with the
Homestead convertible mortgages increased $2.4 million to $86.2 million as of
March 31, 1998.

  Borrowings and Recent Offerings

     PTR has a $350 million unsecured revolving line of credit which had
approximately $135.0 million of borrowings outstanding as of May 8, 1998. The
line of credit matures August 1999 and may be extended annually for an
additional year with the approval of the Lenders. The aggregate amount of
borrowings outstanding under all of PTR's credit facilities as of May 8, 1998
was $142.4 million.

     On March 6, 1998, PTR issued $125 million of 7.20% Long-Term Debt, the
proceeds from which were used to pay down balances on PTR's credit facilities.
The 7.20% Notes pay interest semi-annually on March 1 and September 1 of each
year through March 1, 2013, and have an average effective interest rate of 7.86%
and an average life of 13.0 years. Annual principal payments of $25 million
commence on March 1, 2009.

     On April 23, 1998, PTR sold 2,049,587 Common Shares at $22.6875 per share
in an underwritten public offering. The net proceeds of $44.0 million (net of
underwriting discount and offering costs) were used to repay borrowings

                                      22

under PTR's credit facilities.

     See "Item 1. Financial Statements, Note 5, Borrowings" for additional
information regarding credit availability, outstanding debt balances, interest
rates, scheduled debt maturities and other terms.

  Distributions

     PTR paid the first quarter 1998 distribution of $0.34 per Common Share on
February 25, 1998. On April 29, 1998, the Board declared a cash distribution of
$0.34 per Common Share, payable on May 28, 1998, to shareholders of record on
May 14, 1998. On March 31, 1998, PTR paid quarterly dividends of $0.4579 per
Series A Preferred Share and $0.5625 per Series B Preferred Share.

  Commitments and Contingencies

     At March 31, 1998, PTR had unfunded multifamily construction and
rehabilitation commitments aggregating approximately $230.7 million.

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

     See "Item 7. Management's Discussion and Analysis of Financial Condition
and Results of Operations" included in PTR's Form 10-K for a summary of
anticipated cash requirements.

  Funding Sources

     PTR expects to finance its investment and operating needs including those
outlined above, with cash flow from operating activities, borrowings under its
credit facilities and disposition proceeds from its asset optimization strategy,
prior to arranging long-term financing. PTR uses its credit facilities to
facilitate an efficient response to market opportunities while minimizing the
amount of cash invested in short-term investments at lower yields. Other sources
of future liquidity and financial flexibility include $399.4 million in shelf-
registered securities which can be issued in the form of Long-Term Debt, Common
Shares or preferred shares on an as-needed basis, subject to PTR's ability to
effect offerings on satisfactory terms. PTR believes that its current
conservative ratio of long-term debt to total long-term undepreciated book
capitalization (the sum of long-term debt and shareholders' equity after adding
back accumulated depreciation) of 37.1% at March 31, 1998, provides considerable
financial flexibility to fund its investment activities.

  Funds From Operations

     Funds from operations is defined as net earnings computed in accordance
with GAAP, excluding real estate depreciation, gains (or losses) from
depreciated real estate, provisions for possible losses, non-cash interest
income, extraordinary items and significant non-recurring items. Funds from
operations should not be considered as an alternative to net earnings or any
other GAAP measurement of performance as an indicator of PTR's operating
performance or as an alternative to cash flows from operating, investing or
financing activities as a measure of liquidity. PTR believes that funds from
operations is helpful to the reader as a measure of the performance of an equity
REIT because, along with cash flow from operating, investing and financing
activities, it provides the reader with an indication of the ability of PTR to
incur and service debt, to make capital expenditures and to fund other cash
needs. The funds from operations measure presented by PTR, while consistent with
the National Association of Real Estate Investment Trusts' definition, will not
be comparable to similarly titled measures of other REIT's which do not compute
funds from operations in a manner consistent with PTR. Funds from operations is
not intended to represent cash made available to shareholders. Cash
distributions paid to shareholders are described above under "--Distributions."
