  Unless otherwise indicated, this Prospectus Supplement assumes the sale of
1,486,686 Common Shares in this Offering and the sale of 7,433,433 Common
Shares in the Rights Offering (as defined below).
 
RIGHTS OFFERING
 
  On August 6, 1997, PTR commenced a rights offering (the "Rights Offering")
pursuant to which it distributed to its shareholders transferable rights
("Rights") to subscribe for and purchase up to 7,433,433 Common Shares at a
subscription price of $21.8125 per Common Share. Simultaneously with the
offering of Common Shares to Rights holders, Security Capital Markets Group
Incorporated ("Capital Markets Group"), which is owned by PTR's principal
shareholder, Security Capital Group Incorporated ("Security Capital"), sought
third-party purchasers, on a best efforts basis, to acquire Common Shares that
were not purchased through the exercise of Rights ("Unsubscribed Shares").
Unsubscribed Shares were also available to shareholders who oversubscribed for
additional Common Shares. PTR will be issuing all of the 7,433,433 Common
Shares available in connection with the Rights Offering, whether through the
exercise of Rights, exercise of the oversubscription privilege of shareholders
or sales to third parties. The Rights Offering expired on September 9, 1997,
and Common Shares purchased pursuant thereto will be issued by September 16,
1997.
 
THE MERGER
 
  On September 8, 1997, the shareholders of PTR voted to approve the merger
(the "Merger") of PTR's REIT manager, Security Capital Pacific Incorporated
(the "REIT Manager" or "REIT Management"), and its property manager, SCG
Realty Services Incorporated ("SCG Realty Services"), into a newly formed
subsidiary of PTR. See "The Merger Transaction". Prior to the Merger, which
closed on September 9, 1997, the REIT Manager and SCG Realty Services were
owned by Security Capital. After giving effect to this Offering, the Rights
Offering and the Merger, Security Capital will own approximately 33% of the
outstanding Common Shares.

  PTR is a real estate operating company focused on acquiring, developing,
owning and operating multifamily communities in the western United States. PTR
believes that it distinguishes itself from its competition by being the only
company in its target market which combines all of the following:
 
    1. A disciplined investment strategy based on proprietary research which
  identifies high growth markets and submarkets with attractive long-term
  demand and supply fundamentals for PTR's multifamily communities;
 
    2. Development experience and proven capability to deliver consistent,
  state-of-the-art multifamily communities which meet renter preferences and
  demographic trends;
 
    3. A focus on moderate income product which serves one of the largest
  segments of the renter population and which PTR believes has very
  attractive operating characteristics;
 
    4. An investment strategy which allows PTR to redeploy its invested
  capital and maximize the growth in cash flow generated by PTR's operating
  multifamily communities;
 
    5. An organization of 259 professionals in 14 offices which combines
  local market expertise with broad operating company experience.
 
  The cornerstone of PTR's growth strategy is its commitment to fundamental
real estate research, allowing PTR to deploy and redeploy its capital into
markets, products and new business opportunities which PTR believes have the
greatest potential for long-term cash flow growth. Management believes that
this unique, research-driven strategy will continue to allow PTR to produce
attractive long-term returns for its shareholders.

  At June 30, 1997, PTR's portfolio consisted of 50,564 multifamily units,
including 9,778 units under construction or in planning and owned. The total
expected investment of PTR's portfolio at June 30, 1997, including budgeted
renovations and development expenditures, was $2.7 billion, including $642.7
million under construction or in planning and owned. In addition, as of the
same date, PTR had contingent contracts or letters of intent, subject to PTR's
final due diligence and approval of all entitlements, to acquire land for the
development of an estimated 6,602 multifamily units with a total budgeted
development cost of approximately $612.7 million and owned land for the future
development of an expected 1,254 multifamily units with a total budgeted
development cost of $67.2 million.
 
  The table below illustrates the growth in PTR's multifamily portfolio, based
on total expected investment, resulting from the execution of its investment
strategy since 1991:

  Highlights of PTR's recent strategic accomplishments include:
 
  . PTR's strong growth in the second quarter of 1997 was driven primarily by
    the successful implementation of its investment strategy, with
    development activity generating 42% of the growth in pro forma funds from
    operations and acquisition activity generating 49%. The remaining 9% of
    growth in pro forma funds from operations was produced by an increase in
    net operating income for PTR's same-store multifamily portfolio, which
    achieved net operating income growth of 3.03% compared with 1996. For
    purposes of this paragraph only, pro forma funds from operations for 1996
    has been calculated as if the Homestead transaction described below had
    occurred on January 1, 1996 (but without giving effect to any other
    events which are adjusted for in PTR's pro forma condensed financial
    statements incorporated by reference herein). For a description of how
    PTR calculates funds from operations and certain limitations in the use
    of funds from operations as a performance measure, see "Management's
    Discussion and Analysis of Financial Condition and Results of Operation--
    Liquidity and Capital Resources--Funds from Operations".
 
  . Based on proprietary market research, PTR identified certain submarkets
    in California, the Pacific Northwest and Salt Lake City which it believes
    have favorable market fundamentals and high barriers to entry for new
    supply that are expected to result in significant growth in multifamily
    rental revenues. Through the successful execution of all three components
    of PTR's investment strategy (developments, acquisitions and
    dispositions) during the last 19 months, PTR has significantly increased
    the percentage of its capital which is deployed in these markets. As of
    June 30, 1997, 51% of PTR's capital is now deployed in California, the
    Pacific Northwest and Salt Lake City (based on total expected investment
    for
 
                                      S-4
<PAGE>
 
   operating communities and development communities under construction).
   During the second quarter of 1997, average revenue growth for PTR's same-
   store communities in these markets was 8.28%.
 
  . The development of moderate income multifamily communities is an
    important component of PTR's long-term growth strategy. In the first six
    months of 1997, PTR commenced construction on 1,925 multifamily units,
    representing a total expected investment of approximately $131.6 million.
    Of that total, 1,084 units, or 56.3%, were moderate income. At June 30,
    1997, PTR had 6,672 units under construction, representing a total
    expected investment of $435.2 million.
 
  . PTR continues to take advantage of attractive acquisition opportunities
    in California, the Pacific Northwest and Salt Lake City. During the first
    six months of 1997, PTR completed the acquisition of 3,717 operating
    units in California and Seattle, representing a total expected investment
    of $331.5 million. At June 30, 1997, PTR owned operating communities
    representing a total expected investment of $875.3 million in California
    and Seattle.
 
  . Since December 1995 and through June 30, 1997, PTR has demonstrated its
    ability to dispose of existing assets and efficiently redeploy the
    proceeds into multifamily investments with more attractive long-term
    growth prospects. The success of this asset optimization strategy was
    evidenced by the disposition of 12,835 multifamily units, realizing an
    aggregate gain of approximately $77.2 million on aggregate gross proceeds
    of approximately $549.4 million, which were redeployed, primarily through
    tax-deferred exchanges, into strategic acquisitions in targeted western
    submarkets.
 
  . PTR continues to focus on maintaining a strong balance sheet. PTR has a
    significant equity base with a total equity market capitalization of $2.1
    billion at June 30, 1997. A key component of PTR's conservative financial
    strategy is the issuance of unsecured long-term debt that, in the
    aggregate, has a relatively level amortization schedule which PTR
    believes is unusual among multifamily REITs. At June 30, 1997, PTR's $630
    million in long-term unsecured debt had an effective average fixed
    interest rate of 7.64% and an original weighted-average life to maturity
    of 13.37 years. PTR's long-term debt as a percentage of total long-term
    undepreciated book capitalization (the sum of long-term debt and
    shareholders' equity after adding back accumulated depreciation) was
    37.70% at June 30, 1997 on an historical basis and 34.85% at June 30,
    1997 as adjusted to give effect to the Merger and to the Rights Offering
    and this Offering (assuming the sale of all Common Shares offered in this
    Offering) and the application of the net proceeds therefrom.
 
  . On October 17, 1996, PTR contributed its Homestead Village(R) properties
    to a newly formed company, Homestead Village Incorporated ("Homestead"),
    in exchange for Homestead common stock and entered into a funding
    commitment agreement to fund the development of certain of such
    properties in exchange for warrants to purchase Homestead common stock.
    The Homestead common stock and warrants were subsequently distributed to
    PTR's common shareholders (the "Homestead Distribution"). On a fully
    funded and converted basis, PTR will own 34.7% of Homestead's common
    stock (assuming no further equity offerings by Homestead, conversion of
    all Homestead convertible mortgage notes by PTR and Security Capital
    Atlantic Incorporated ("ATLANTIC") and exercise of all outstanding
    warrants) as a result of its obligation to fund up to $198.8 million to
    Homestead in exchange for up to $221.3 million of Homestead convertible
    mortgage notes (the "Homestead Notes"). The Homestead Notes are expected
    to contribute significantly to PTR's future growth. See "Management's
    Discussion and Analysis of Financial Condition and Results of
    Operations--Results of Operations--Homestead Interest and Homestead
    Notes." The Homestead common stock and warrants trade on the American
    Stock Exchange (the "ASE") under the symbols "HSD" and "HSD.W",
    respectively.
 
  As a result of the Merger, which was consummated on September 9, 1997, PTR
is a fully integrated operating company. See "The Merger Transaction" for a
description of the Merger whereby Security Capital, which owned the REIT
Manager and SCG Realty Services, caused the REIT Manager and SCG Realty
Services to merge into a newly formed subsidiary of PTR in exchange for Common
Shares.
 
  PTR has elected to be taxed as a REIT for federal income tax purposes and
was organized in 1963 as a real estate investment trust under the laws of
Maryland. Its principal executive offices are located at 7670 South Chester
Street, Suite 100, Englewood, Colorado 80112, and its telephone number is
(303) 708-5959.

                                   BUSINESS
 
PTR'S OPERATING SYSTEM AND BUSINESS STRATEGY
 
  PTR has approximately 259 professionals dedicated to implementing PTR's
highly focused, fully integrated business strategy using PTR's "Operating
System". PTR's Operating System consists of seven functional areas:
fundamental real estate research, opportunistic acquisitions, multifamily
developments, comprehensive due diligence and investment analysis, asset
optimization, customer-focused property management and an efficient capital
markets/finance function. By focusing on a single discipline, professionals
within each of these areas develop substantial expertise commensurate with
their respective skills and responsibilities. All of these functional areas
are integrated by senior management but PTR believes that the focus on
separate disciplines by key personnel improves its overall results. PTR
utilizes the extensive capabilities of its Operating System to execute its
business strategy in order to achieve PTR's primary objective of generating
long-term, sustainable growth in per share cash flow.
 
 Commitment to Fundamental Real Estate Research
 
  PTR is dedicated to a continuing investment in leading edge research and
development for markets, products and new business opportunities. PTR utilizes
Security Capital Real Estate Research Group Incorporated ("Security Capital
Real Estate Research"), an affiliate of PTR, to conduct comprehensive
evaluations of its target market on a submarket-by-submarket basis to identify
those submarkets that offer strong prospects for long-term cash flow growth.
These evaluations, combined with PTR's extensive market experience throughout
its target market, enable PTR to identify submarkets that will offer
attractive growth opportunities.
 
  For each submarket, PTR's research evaluates 24 key variables that PTR has
identified as having the greatest impact on multifamily operating performance.
This research provides PTR with the information needed to target specific
resident profiles and identify the unit mix, density and amenities for each
community which will provide the greatest opportunity for consistent rental
increases and high occupancies. PTR also evaluates and continually refines its
multifamily communities to incorporate technologies and designs that will
enhance long-term resident satisfaction.
 
  In addition to dedicated market research and continuous refinement of the
traditional multifamily product, considerable resources are devoted to
researching new products and businesses. The Homestead Village(R) extended-
stay lodging product is an example of PTR's research and development efforts
which resulted in the creation of an exciting new growth company, Homestead,
and resulted in the Homestead Distribution which occurred in November 1996.
 
  Another innovative product concept developed by PTR is its master-planned
apartment neighborhood, or "village", concept. These "village" communities
offer residents an extraordinary level of amenities, including greenbelt
areas, soccer and baseball fields, sports courts and large clubhouses with
features such as theaters, business centers and community resource centers.
PTR believes the "village" concept will generate consistent, long-term growth
by providing a large segment of the renter population with amenities far
beyond those which are available in traditional multifamily developments. PTR
currently has two "village" communities in operation and two additional
communities in planning.
 
 Opportunistic Acquisitions
 
  PTR opportunistically acquires multifamily communities where demographic and
market trends indicate a high likelihood of achieving attractive, sustainable
operating results. This strategy has resulted in multifamily community
acquisitions which have produced attractive returns. Since inception and
through June 30, 1997, PTR had acquired 44,871 operating units representing a
total expected investment of approximately $2.1 billion. Since early in 1996,
PTR specifically focused its acquisition efforts on California, because its
research identified the opportunity for very strong growth in operating
performance there. PTR acquired a total of 8,368 operating
 
                                      S-6
<PAGE>
 
multifamily units, representing a total expected investment of $642.4 million,
in targeted California submarkets during 1996 and 1997. Additionally, at June
30, 1997, PTR had letters of intent or contingent contracts, subject to PTR's
final due diligence, for the acquisition of 328 units in Salt Lake City,
representing a total expected investment of $17.5 million. This significant
acquisition activity is expected to be an important source of PTR's future
growth.
 
  PTR categorizes operating multifamily communities (which include all
communities not in development) 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 and in effect 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". Due to its active
investment program, 24% of PTR's multifamily operating portfolio, based on
total expected investment, was classified by PTR as pre-stabilized at June 30,
1997.
 
  At June 30, 1997, PTR's operating multifamily communities (excluding
communities in lease-up) were 94% occupied. For operating communities which
PTR has acquired, stabilized operations generally have been achieved six to 12
months after acquisition. For communities which it is developing, PTR expects
stabilized operations generally to be achieved 18 to 24 months after
construction commences.
 
 Multifamily Developments
 
  PTR selectively develops multifamily communities where land costs,
demographics and market trends indicate a high likelihood of achieving
sustainable operating results and consistent cash flow growth. This
disciplined approach to development has produced multifamily property
developments with desired characteristics including state-of-the-art product,
protected locations and attractive returns. Through June 30, 1997, completed
development communities, communities under construction and communities in
planning and owned represented 41.0% of PTR's multifamily portfolio, based on
total expected investment. At June 30, 1997, PTR's multifamily development
portfolio consisted of the following:

    expenditures at June 30, 1997, which include the cost of land, fees,
    permits, payments to contractors, materials, architectural and engineering
    fees and interest and property taxes to be capitalized during the

  PTR's research-driven development strategy is to focus on developing state-
of-the-art communities in attractive submarkets to meet renter preferences and
demographic trends. Development opportunities also permit PTR to incorporate
into its multifamily communities proprietary technologies and designs aimed at
enhancing long-term rental growth while reducing ongoing maintenance costs.
PTR has had the opportunity to evaluate and refine its multifamily product
through its long history of development (PTR has developed multifamily
communities since 1970). PTR, unlike a typical merchant builder, intends to be
a long-term owner of the communities that it develops. Hence, PTR emphasizes
durability by using materials and designs with an added view toward minimizing
ongoing operating and maintenance costs.

  PTR carefully manages development risks by obtaining zoning and
discretionary municipal approvals prior to purchasing land. PTR does not
assume construction risk, but instead uses qualified third-party general
contractors to build its communities, using guaranteed maximum price
contracts. PTR cannot eliminate all development risk, but believes that the
opportunities to better control product and realize higher returns from
development communities compensate for the limited risk.
 
  PTR traditionally has commenced development immediately after acquiring a
tract of land. However, in certain cases where land prices are favorable and
zoned land is very limited, PTR has acquired and will acquire, on an
unleveraged basis, prudent amounts of land zoned for multifamily use. In
addition, to allow for entitlements to be finalized prior to purchasing the
land, PTR often utilizes options and rights of first refusal in order to
control land for future developments with minimal cash investments. The land
that PTR owns or controls provides a foundation for future growth by providing
a pipeline of future developments at attractive prices.
 
  To enhance its flexibility in developing and acquiring communities, PTR may
also from time to time enter into presale agreements with third-party
owner/developers to acquire development communities which meet PTR's
investment criteria. PTR has and will fund such developments through
development loans to these owner/developers. In addition, to provide greater
flexibility for the use of land acquired for development and to facilitate
disposition of excess parcels, PTR has and will make mortgage loans to PTR
Development Services Incorporated ("PTR Development Services") to purchase
land for development. PTR may also fund developments of multifamily
communities by PTR Development Services where the particular community or
submarket does not meet PTR's objectives for long-term ownership but presents
an attractive investment opportunity. PTR owns all of the preferred stock of
PTR Development Services, which entitles PTR to substantially all of the net
operating cash flow (95%) of PTR Development Services. All of the common stock
of PTR Development Services is owned by an unaffiliated trust, which is
entitled to the remaining 5% of net operating cash flow. At June 30, 1997, PTR
had development and mortgage loans outstanding to third-party owner/developers
and PTR Development Services aggregating $109.0 million and $19.4 million,
respectively. The activities of PTR Development Services and third-party
owner/developers are consolidated with PTR's activities and all intercompany
transactions have been eliminated in consolidation.
 
 Moderate Income Product
 
  PTR focuses its development efforts primarily on moderate income
communities, which target households with incomes that range from 65-90% of
the median household income in the submarket. These households represent one
of the largest segments of the multifamily renter market. Residents in this
category are value-driven and focus on unit livability and practical amenities
such as washer/dryer hookups, storage space and lower density communities with
attractive landscaping. PTR's moderate income product comprised 71.3% of PTR's
development starts during 1996, based on number of units. Based on PTR's
review of information filed under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), regarding other REITs in PTR's primary target
market and other publicly available data, PTR believes that few other REITs
currently focus on the moderate income segment within PTR's primary target
market. Moreover, based on PTR's proprietary information regarding available
land parcels and construction starts in its primary target market, PTR
believes that less than 15% of the 1995 and 1996 multifamily development
starts in PTR's primary target market cities were moderate income product.
Consequently, PTR believes that the moderate income segment is a significantly
underserved market with limited competition. PTR believes that focusing on
this segment will allow PTR to achieve more consistent rental increases and
higher occupancies over the long term and, thereby, realize above average,
sustainable cash flow growth and appreciation in value.
 
  In PTR's experience, moderate income residents are typically longer-term
residents because they often lack the financial resources required to purchase
single-family homes. As a result, resident turnover is often lower in PTR's
moderate income communities than in its upper middle income communities (which
target households with incomes that range from 115-140% of the median
household income in the submarket) and middle income
 
                                      S-8
<PAGE>
 
communities (which target households with incomes that range from 90-115% of
the median household income in the submarket). PTR estimates that the total
cost of refurbishing and re-leasing a unit ranges from $700 to $1,500;
therefore, reducing resident turnover can have a material impact on a
community's cash flow. Due to market fundamentals and the operating
characteristics of moderate income communities, PTR believes that this product
category offers greater sustainable cash flow growth.
 
 Comprehensive Due Diligence and Investment Analysis
 
  PTR believes that comprehensive due diligence is essential prior to
investing in acquisitions or developments. PTR employs nine full-time
professionals who perform due diligence for PTR. This due diligence team is an
important resource which allows PTR to effectively and efficiently close a
large volume of investment transactions, while thoroughly evaluating all
potential aspects of risk in each transaction. This capability provides PTR
with a competitive advantage in acquiring both operating communities and land.
 
  Prior to purchasing an asset, the due diligence team works in tandem with
PTR's development and operations professionals to thoroughly investigate the
following factors: market conditions; competitive communities and
developments; comparable sales and rents; existing and projected income and
expenses; current and targeted resident profiles; present and projected
capital requirements for community acquisitions; development costs for land
purchases; and potential liability issues such as environmental and title
conditions, tax increases, special assessments and code compliance. In
addition, for land acquisitions, all discretionary development approvals are
obtained prior to closing, thus ensuring that projected development costs are
quantified with a high degree of accuracy and the risk of construction delay
is minimized.
 
  With the comprehensive data available from research, development and
operating professionals, standard financial underwriting is completed on an
unleveraged basis in order to evaluate each investment's yield and its
prospects for long-term growth in cash flow. PTR's management investment
committee, which consists of five members having a combined 77 years of
experience in the real estate industry, evaluates all prospective investments
prior to submission of investment recommendations to the investment committee
of PTR's Board of Trustees (the "Board").
 
 Asset Optimization Strategy
 
  The ability to dispose of existing assets and efficiently redeploy the
proceeds into communities and submarkets having more attractive long-term
growth prospects is an important component of PTR's investment strategy. Each
year, management formulates operating and capital plans based on an ongoing
active review of PTR's portfolio. Based in part upon the market research
provided by Security Capital Real Estate Research and in an effort to optimize
its portfolio composition, PTR may, from time to time, seek to dispose of
assets that in management's view no longer meet PTR's long-term investment
objectives. The proceeds from these selected dispositions will be redeployed,
typically through tax-deferred exchanges, into assets that in PTR's view offer
better long-term cash flow growth prospects. This allows PTR to continually
reposition its portfolio by redeploying capital into communities and markets
with superior growth characteristics.
 
  PTR's asset optimization strategy is based on the premise that it has a
finite amount of investment capital and that this capital should be deployed
where it can produce the highest levels of cash flow growth. PTR has
demonstrated the ability to enter and exit submarkets based on future growth
expectations and the supply/demand fundamentals of the submarkets in which it
operates. Since PTR's asset optimization program commenced in December 1995
and through June 30, 1997, PTR had completed the disposition of 12,835
multifamily units, realizing aggregate gains of $77.2 million on aggregate
gross proceeds of $549.4 million. The proceeds were redeployed into targeted
submarkets in California, the Pacific Northwest and Salt Lake City to allow
PTR to take advantage of the strong economic recovery which is underway in
these markets. PTR's expected investment in these markets grew from 17% of
PTR's total portfolio at December 31, 1995, to 51% of PTR's total portfolio at
June 30, 1997, based on total expected investment.

Customer-Focused Property Management
 
  PTR believes that its communities must be actively managed in order to
maximize cash flow and enhance long-term economic performance. At June 30,
1997, approximately 94% of PTR's operating multifamily communities were
managed by PTR, based on total expected investment, with the balance of the
communities in various stages of transition to PTR's management.
 
  PTR has over 1,250 employees and emphasizes locally-based management of its
multifamily communities. PTR has 14 local offices to serve its target market.
This network improves PTR's ability to anticipate and respond to changes in
local market conditions and resident needs. PTR believes that it has developed
superior operating procedures, financial controls, information systems and
training programs, which it expects will positively affect growth in rental
and occupancy rates. PTR develops systems and procedures which facilitate
effective management of its communities.
 
  PTR recognizes that a highly focused customer service approach to day-to-day
management is essential to maximize short and long-term cash flow growth from
each of its multifamily communities. As a result, PTR is dedicated to
maximizing the performance of its communities by providing consistent, high
quality residential services to its customers. PTR works to develop innovative
ideas to enhance customer service and resident satisfaction while maximizing
cash flow growth.
 
  A few of the programs which have been developed recently and are currently
in the process of being implemented are summarized below:
 
  . During 1996, SCG Realty Services established five Regional Information
    Management ("RIM") Centers. The RIM Center concept is designed to enable
    property-level management personnel to focus on PTR's customers, the
    residents, while moving certain accounting and administrative functions
    to the regionally located RIM Center. Each RIM Center is designed to
    carry out these functions for several area communities and thus benefit
    from economies of scale, better accounting control and enhanced cash
    management capabilities. PTR expects to eventually implement the RIM
    Center concept at all of its operating communities.
 
  . SCG Realty Services and the REIT Manager had also initiated resident
    utility billing programs at approximately 90% of PTR's multifamily
    operating communities at June 30, 1997. Under this arrangement, water and
    sewer usage are metered and billed to individual residents, thereby
    enabling PTR to better control operating expenses, while providing
    residents with the incentive to minimize usage.
 
  . In late 1996, PTR entered into revenue sharing agreements with certain
    cable television and telephone service providers. The arrangements
    require the telecommunication providers to continually upgrade service to
    ensure state-of-the-art offerings in this rapidly changing industry. The
    agreements also allow PTR to receive a percentage of the service
    providers' revenues generated from subscribing residents while increasing
    the quality and accessibility of these services to residents.
 
  These creative initiatives coupled with highly focused day-to-day management
are expected to contribute to the growth in net operating income generated by
PTR's multifamily operating communities.
 
 Capital Markets/Finance and Conservative Balance Sheet Strategy
 
  PTR believes that a successful REIT must maintain a strong balance sheet and
have the ability to access the equity and debt markets efficiently,
expeditiously and cost effectively. PTR's ability to efficiently access the
capital markets permits it to capitalize on development and acquisition
opportunities that PTR identifies in its target market.
 
  PTR continues to focus on maintaining its strong balance sheet which has
resulted from a conservative balance sheet strategy. PTR has a significant
equity base with a total equity market capitalization of $2.1 billion at June
30, 1997. A key component of PTR's conservative balance sheet strategy is the
issuance of fixed rate, unsecured, long-term debt. In order to minimize
refinancing risk, PTR's long-term debt offerings are carefully
 
                                     S-10
<PAGE>
 
structured to create a relatively level principal maturity schedule, without
large repayment obligations in any future year. At June 30, 1997, PTR's $630
million in unsecured long-term debt had an effective average fixed interest
rate of 7.64% and an original weighted-average life to maturity of 13.37
years. PTR's long-term debt as a percentage of total long-term undepreciated
book capitalization (the sum of long-term debt and shareholders' equity after
adding back accumulated depreciation) was 37.70% at June 30, 1997 on an
historical basis and 34.85% at June 30, 1997 as adjusted to give effect to the
Merger and to the Rights Offering and this Offering (assuming the sale of all
Common Shares offered in this Offering) and the application of the net
proceeds therefrom.
 
  PTR's credit facilities, including its $350 million unsecured revolving line
of credit, provide PTR with the financial flexibility to take advantage of
attractive investment opportunities prior to raising capital through
securities offerings. Additionally, such facilities minimize the amount of
cash which must be invested in short-term investments at low yields prior to
the deployment of the capital.
 
  PTR's conservative balance sheet strategy is expected to provide significant
incremental debt capacity and allow PTR to take advantage of future investment
opportunities which will contribute to PTR's objective of long-term growth in
cash flow per share.
 
GEOGRAPHIC DISTRIBUTION
 
  To effectively manage its multifamily communities, PTR has organized its
operations into three regions (Central, Northwest and West). Within these
regions, PTR's multifamily communities are located in 23 metropolitan areas in
12 states. The table below summarizes the geographic distribution of PTR's
multifamily communities which are operating or under construction, based on
total expected investment.

                                USE OF PROCEEDS
 
  The net proceeds to PTR from the sale of the Common Shares offered hereby
are expected to be approximately $32.4 million, all of which are expected to
be used to repay borrowings under PTR's credit facilities, including its $350
million unsecured revolving line of credit and its short-term borrowing
agreement (the "TCB Agreement") with Texas Commerce Bank, National Association
("TCB"). The line of credit 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 September 8, 1997) or
the federal funds rate plus 0.50%, or at PTR's option, LIBOR (5.6875% at
September 8, 1997) plus 0.75% (6.4375% at September 8, 1997). 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. Loans under the TCB Agreement bear
interest at an overnight rate, which ranged from 5.94% to 7.00% during the six
months ended June 30, 1997. At September 8, 1997, $151.3 million in borrowings
were outstanding under the line of credit and $14.3 million in borrowings were
outstanding under the TCB Agreement. The aggregate amount of borrowings
outstanding under all of PTR's credit facilities as of September 8, 1997 was
$265.5 million. PTR expects to make additional borrowings under the line of
credit and the TCB Agreement following this Offering. Borrowings under the
line of credit and the TCB Agreement are used for the development and
acquisition of multifamily communities and for working capital purposes.

 DISTRIBUTIONS
 
  In order to qualify as a REIT, PTR is required to make distributions (other
than capital gain distributions) to its shareholders in amounts at least equal
to (i) the sum of (A) 95% of its "REIT taxable income" (computed without
regard to the dividends-paid deduction and its net capital gain) and (B) 95%
of the net income (after tax), if any, from foreclosure property, minus (ii)
the sum of certain items of noncash income. PTR's distribution strategy is to
distribute what it believes is a conservative percentage of its cash flow,
permitting PTR to retain funds for capital improvements and other investments
while funding its distributions. PTR has paid 86 consecutive quarterly cash
distributions on the Common Shares.
 
  PTR announces the following year's projected annual distribution level after
the annual budget review and approval in December of each year by the Board.
At its December 1996 meeting, the Board announced an increase in the annual
distribution level from $1.24 to $1.30 per Common Share. The payment of
distributions is subject to the discretion of the Board and is dependent upon
the financial condition and operating results of PTR.
 
  For federal income tax purposes, distributions may consist of ordinary
income, capital gains, non-taxable return of capital or a combination thereof.
Distributions that exceed PTR's current and accumulated earnings and profits
(calculated for tax purposes) constitute a return of capital rather than a
dividend and reduce the shareholder's basis in the Common Shares. To the
extent that a distribution exceeds both current and accumulated earnings and
profits and the shareholder's basis in the Common Shares, it will generally be
treated as gain from the sale or exchange of that shareholder's Common Shares.
For a more complete discussion of the tax treatment of distributions to

  The Homestead securities distributed by PTR to each holder of Common Shares
in the Homestead Distribution were valued at $2.16 per Common Share for
federal income tax purposes, of which $1.06 was taxable as ordinary income,
$0.19 was taxable as a capital gain and $0.91 was treated as a return of
capital.
 
  On July 21, 1994, in addition to the normal Common Share distributions paid,
PTR redeemed the shareholder purchase rights issued pursuant to the Rights
Agreement dated as of February 23, 1990, as amended. Pursuant to the
redemption, each holder of record at the close of business on July 21, 1994
was entitled to receive $0.01 per shareholder purchase right. The redemption
price was paid on August 12, 1994 and was taxable as ordinary income for
federal income tax purposes.
 
  Under federal income tax rules, PTR's earnings and profits are first
allocated to its preferred shares, which increases the portion of the Common
Shares distribution classified as return of capital.
 
  PTR's tax returns have not been examined by the Internal Revenue Service
(the "IRS") and, therefore, the taxability of distributions is subject to
change.

                            THE MERGER TRANSACTION
 
DESCRIPTION OF THE MERGER
 
  In January 1997, Security Capital made a proposal to the Board that Security
Capital exchange the REIT Manager and SCG Realty Services for Common Shares,
with the result that PTR would become an internally managed REIT. On March 18,
1997, a special committee of independent Trustees of the Board (the "Special
Committee") recommended that the Board approve the Merger subject to
definitive documentation. Following the meeting of the Special Committee, the
full Board approved the Merger and Issuance Agreement between PTR and Security
Capital (the "Merger Agreement") and the Merger. On March 24, 1997, PTR and
Security Capital entered into the Merger Agreement, pursuant to which Security
Capital agreed to cause the REIT Manager and SCG Realty Services to be merged
into a newly formed subsidiary of PTR. On September 8, 1997, PTR's common
shareholders voted to approve the Merger, which closed on September 9, 1997.
The employees of the REIT Manager and SCG Realty Services became employees of
PTR as a result of the Merger, which was consummated as follows:
 
  . Security Capital transferred all of its shares of the REIT Manager and
    SCG Realty Services to a newly formed subsidiary of PTR in exchange for
    3,295,533 Common Shares valued at approximately $75.8 million based on
    the average closing price of $23.0125 per Common Share as described
    below.
 
  . The number of Common Shares issuable to Security Capital was based on the
    average closing price of the Common Shares over the five-day period prior
    to the record date for determining PTR's shareholders entitled to vote at
    the meeting in connection with the Merger (which was the same as the
    record date for the Rights dividend). The average closing price of the
    Common Shares over the five-day period prior to such record date was
    $23.0125 per Common Share. The subscription price for the Rights Offering
    (and the offering price for this Offering) was equal to 94.8% of such
    average price.
 
  . The Rights Offering was designed to allow PTR's shareholders (other than
    Security Capital) the opportunity to maintain (and, to the extent a
    shareholder successfully oversubscribed for Common Shares pursuant to the
    oversubscription privilege, to increase) their relative ownership in PTR
    by purchasing additional Common Shares at a price which was below the
    price at which Security Capital received Common Shares in the Merger.
    Security Capital agreed that it would not exercise its Rights to purchase
    additional Common Shares and that it would not sell its Rights.
 
  . In addition to the Rights Offering, as part of the Merger transaction,
    Security Capital will issue warrants (the "Warrant Issuance") pro rata to
    holders of PTR's Common Shares and Series A Cumulative Convertible
    Preferred Shares (the "Series A Preferred Shares"), other than Security
    Capital, to acquire shares of Security Capital's Class B common stock,
    par value $.01 per share (the "Class B Stock"), having an aggregate
    subscription price at the time of the Warrant Issuance of approximately
    $102 million. The Warrant Issuance was intended to induce holders of
    Common Shares to vote in favor of the Merger transaction, to broaden
    Security Capital's shareholder base, to enable Security Capital to raise
    additional equity capital at a relatively low cost through exercises of
    warrants and to enable Security Capital to raise additional equity
    capital in the long run by preserving and enhancing its goodwill with the
    shareholders of PTR. The Warrant Issuance will occur after the closing of
    the Merger and the Rights Offering and this Offering. The number of
    shares of Class B Stock subject to the warrants will be based on the
    closing price of the Class B Stock on the date the warrants are issued to
    the agent for the Warrant Issuance for subsequent distribution to holders
    of Common Shares and Series A Preferred Shares, other than Security
    Capital. The warrants will expire one year after issuance and will
    contain customary provisions to protect shareholders from dilution in
    certain events, including certain distributions and sales of shares of
    Class B Stock at less than market price. Any securities issued pursuant
    to the Warrant Issuance will be offered only by means of a separate proxy
    statement/prospectus which will be delivered to PTR's shareholders.
 
  No shareholder will be required to pay any cash or other consideration for
the warrants received in the Warrant Issuance or surrender or exchange Common
Shares in order to receive warrants. However, PTR believes that a shareholder
receiving warrants pursuant to the Warrant Issuance should have ordinary
taxable income
 
                                     S-15
<PAGE>
 
equal to the value of the warrants on the issuance date. See "Federal Income
Tax Considerations--Tax Effects of the Merger".
 
  The Board believes that the Merger will result in an enhancement to
shareholder value. Prior to the Merger, PTR paid a fee to the REIT Manager
based on a fixed percentage of PTR's cash flow (as defined) which increased
proportionately as PTR added assets. The Board believes that PTR has reached a
sufficient size to realize economies of scale by internalizing the management
function since PTR will have sufficient depth of management and personnel such
that additional assets can be acquired, developed and managed without a
significant increase in personnel or other costs. These economies of scale
should result in an increase in the level of growth in funds from operations.
The Board believes that the Merger will further benefit PTR's long-term
performance as follows:
 
  . The Merger will position PTR to pursue possible acquisitions of other
    REITs in a more effective way.
 
  . Investors and analysts will view an internally managed structure more
    favorably since PTR's costs, after capitalization of qualifying
    acquisition and development costs in accordance with generally accepted
    accounting principles ("GAAP"), will be more comparable to other
    multifamily REITs. These acquisition and development activities were
    previously provided by the REIT Manager and paid for as part of the REIT
    Management fee, which fee was expensed by PTR. Management believes that
    the increased comparability, in addition to the opportunity for increased
    funds from operations growth due to the economies of scale, as discussed
    above, will result in a higher multiple on PTR's funds from operations
    and an enhancement to shareholder value.
 
  . As a consequence of the REIT Manager's and SCG Realty Services' personnel
    becoming full-time employees of PTR, they will be able to more closely
    relate the results of their efforts to PTR's performance.
 
  . The Merger may result in improvement to PTR's debt rating, which could
    have a positive impact on PTR's future debt cost.
 
  The following are certain potential detriments of the Merger:
 
  . The Warrant Issuance will be taxable to holders of Common Shares and
    Series A Preferred Shares.
 
  . The REIT Manager and SCG Realty Services were not profitable. The fees
    paid by PTR for the REIT Manager's and SCG Realty Services' services in
    1996 were approximately $832,000 less than the direct costs and indirect
    costs incurred by Security Capital in providing these services.
 
  . The Merger transaction will result in PTR recording higher administrative
    expenses related to the internalization of the management function in
    lieu of paying a fee to the REIT Manager and SCG Realty Services.
    Security Capital has anticipated that PTR would incur approximately $25.8
    million of additional administrative expenses in 1998 by internalizing
    the management function. Of these expenses, an amount which is subject to
    a maximum limit of $5.5 million for 1998, is expected to be purchased
    from Security Capital under an administrative services agreement. See "--
    Relationship With Security Capital After the Merger--Administrative
    Services Agreement". PTR will, however, no longer pay estimated REIT
    management and property management fees of $35.6 million in 1998. The
    increased administrative costs of internalizing the management function
    may be greater than anticipated and no assurance can be given that the
    cost to PTR of providing such services internally will not exceed the
    fees paid to the REIT Manager and SCG Realty Services under the prior
    agreements.
 
  . Although the Merger is expected to be immediately accretive to PTR's
    funds from operations, the Merger may not result in a corresponding
    increase in the price at which Common Shares trade on the NYSE.
 
  The Merger transaction was initiated and structured by individuals who are
executive officers of Security Capital, the largest shareholder of PTR.
Although no independent representatives were retained to negotiate the terms
of the Merger transaction on behalf of PTR, the Board created the Special
Committee consisting of Messrs.
 
                                     S-16
<PAGE>
 
John Schweitzer, Calvin Kessler and James Cardwell. The Special Committee
engaged Munger, Tolles & Olson LLP as its legal counsel and engaged Robertson,
Stephens & Company LLC as its financial advisor to advise it in analyzing and
evaluating, and to provide a written opinion with respect to, the fairness of
the Merger transaction to PTR and the holders of Common Shares (other than
Security Capital). No member of the Special Committee is an officer of PTR or
a director or officer of the REIT Manager or SCG Realty Services or an officer
or director of Security Capital. However, at August 6, 1997, Messrs.
Schweitzer, Kessler and Cardwell beneficially owned 34,602, 32,267 and 32,765
Common Shares, respectively, and Mr. Schweitzer beneficially owned 268 shares
of Security Capital's Class A common stock, par value $.01 per share (the
"Class A Stock"). Additionally, at August 6, 1997, Mr. Schweitzer beneficially
owned $203,219 aggregate principal amount of Security Capital's Convertible
Subordinated Debentures due 2014 (the "2014 Convertible Debentures")
(convertible into an aggregate of 194 shares of Class A Stock). Trustees of
PTR, other than members of the Special Committee, at August 6, 1997,
beneficially owned in the aggregate 117,272 Common Shares, 11,811 shares of
Class A Stock, $3,012,347 aggregate principal amount of 2014 Convertible
Debentures (convertible into an aggregate of 2,879 shares of Class A Stock)
and $500,000 aggregate principal amount of Security Capital's Convertible
Subordinated Debentures due 2016 (convertible into an aggregate of 433 shares
of Class A Stock). Beginning January 1, 1998, each share of Class A Stock will
be convertible into 50 shares of Class B Stock.
 
  Concurrently with signing the Merger Agreement with PTR, Security Capital
also signed substantially similar agreements with each of ATLANTIC and
Security Capital Industrial Trust ("SCI"), each of which are affiliates of
Security Capital and PTR. The ATLANTIC and SCI transactions also closed on
September 9, 1997.
 
RELATIONSHIP WITH SECURITY CAPITAL AFTER THE MERGER
 
  Amended and Restated Investor Agreement
 
  As part of the Merger transaction, PTR and Security Capital amended and
restated various agreements (as so amended and restated, the "Amended and
Restated Investor Agreement"), to provide that, without first having consulted
with the nominees of Security Capital designated in writing, PTR may not seek
Board approval of (i) PTR's annual budget; (ii) incurring expenses in any year
exceeding (a) any line item in the annual budget by the greater of $500,000 or
20% and (b) the total expenses set forth in the annual budget by 15%; (iii)
the acquisition or sale of any assets in any single transaction or series of
related transactions in the ordinary course of PTR's business where the
aggregate purchase price paid or received by PTR exceeds $25 million; and (iv)
entering into any new contract with a service provider (a) for investment
management, property management or leasing services or (b) that reasonably
contemplates annual contract payments by PTR in excess of $1 million. PTR is
under no obligation to accept or comply with any advice offered by Security
Capital with respect to the foregoing matters.
 
  Additionally, so long as Security Capital beneficially owns at least 25% of
the Common Shares, Security Capital has the right to approve the following
matters proposed by PTR: (i) the issuance or sale of any Common Shares
(including the grant of any rights, options or warrants to subscribe for or
purchase Common Shares or any security convertible into or exchangeable for
Common Shares or the issuance or sale of any security convertible into or
exchangeable for Common Shares) at a price per share less than the fair market
value of a Common Share on the date of such issuance or sale; (ii) the
issuance and sale of any disqualified shares (as defined) if, as a result
thereof, PTR's Fixed Charge Coverage Ratio (as defined) would be less than 1.4
to 1.0; (iii) the adoption of any employee benefit plan pursuant to which
shares of PTR or any securities convertible into shares of PTR may be issued
and any action with respect to the compensation of the senior officers of PTR
(including the grant or award of any bonuses or share-based incentive awards);
and (iv) the incurrence of any additional indebtedness (including guarantees
and including renegotiations and restructurings of existing indebtedness) if,
as a result thereof, PTR's Interest Expense Coverage Ratio (as defined) would
be less than 2.0
 
                                     S-17
<PAGE>
 
to 1.0. The restriction referred to in clause (i) above does not apply to (A)
the sale or grant of any options to purchase shares of beneficial interest of
PTR pursuant to the provisions of any benefit plan approved by the
shareholders of PTR, (B) the issuance or sale of shares of beneficial interest
of PTR upon the exercise of any rights, options or warrants granted, or upon
the conversion or exchange of any convertible or exchangeable security issued
or sold, prior to the closing date of the Merger or in accordance with the
provisions of the Amended and Restated Investor Agreement, (C) the issuance
and sale of any shares of beneficial interest of PTR pursuant to any dividend
reinvestment and share purchase plan approved by the Board or (D) the
issuance, grant or distribution of rights, options or warrants to all holders
of Common Shares entitling them to subscribe for or purchase shares of
beneficial interest of PTR or securities convertible into or exercisable for
shares of beneficial interest.
 
  The Amended and Restated Investor Agreement also provides that, so long as
Security Capital owns at least 10% of the outstanding Common Shares, PTR may
not increase the number of persons serving on the Board to more than eight.
Security Capital also is entitled to designate one or more persons to be
nominated for election to the Board, as follows: (i) so long as Security
Capital owns at least 10% but less than 25% of the outstanding Common Shares,
it is entitled to nominate one person; and (ii) so long as Security Capital
owns at least 25% of the outstanding Common Shares, it is entitled to nominate
that number of persons as bears approximately the same ratio to the total
number of members of the Board as the number of Common Shares beneficially
owned by Security Capital bears to the total number of outstanding Common
Shares, provided that Security Capital is entitled to designate no more than
three persons so long as the Board consists of no more than eight members.
 
  As part of the Amended and Restated Investor Agreement, Security Capital is
permitted to make employment opportunities with Security Capital or its
affiliates available to the officers and employees of PTR. Prior to commencing
discussions with a senior officer of PTR about any such opportunity, Security
Capital is required to give the Board 14 days' prior written notice.
 
  In addition, the Amended and Restated Investor Agreement provides Security
Capital with registration rights pursuant to which, in certain specified
circumstances, Security Capital is permitted to request at any time,
registration of all of Security Capital's Common Shares pursuant to Rule 415
under the Securities Act of 1933, as amended (the "Securities Act"). Security
Capital is permitted to request one such registration for every $100 million
(based on market value) of Common Shares it owns.
 
  Administrative Services Agreement
 
  Upon consummation of the Merger transaction, PTR and Security Capital
entered into an administrative services agreement (the "Administrative
Services Agreement"), pursuant to which Security Capital provides PTR with
certain administrative and other services with respect to certain aspects of
PTR's business, as selected from time to time by PTR at its option. These
services are expected to include, but are not limited to, payroll and tax
administration services, cash management and accounts payable services, data
processing and other computer services, human resources, research, investor
relations, insurance administration and legal administration. The fees payable
to Security Capital will be equal to Security Capital's cost of providing such
services, plus 20%, subject to a maximum amount of approximately $7.7 million
during the initial term of the agreement, of which approximately $2.2 million
will apply to the period between closing of the Merger and December 31, 1997
and the remainder will apply to 1998. Cost savings under the Administrative
Services Agreement will accrue to PTR. The agreement has an initial term
expiring on December 31, 1998 and will be automatically renewed for
consecutive one-year terms, subject to approval by a majority of the
independent members of the Board.
 
  License Agreement
 
  PTR and Security Capital entered into a license agreement on the closing
date of the Merger (the "License Agreement") pursuant to which Security
Capital has granted PTR a non-exclusive license to use Security Capital's
registered logo and the non-exclusive right to use the name "Security
Capital". The term of the license is for a period of 15 years, subject to
PTR's right to extend the license for up to two additional five-year periods.
As part of the License Agreement, Security Capital has agreed that during the
term of the agreement, it will not exercise its rights under the Declaration
of Trust to cause PTR to change its name.
 
                                     S-18
<PAGE>
 
  Protection of Business Agreement
 
  PTR and Security Capital entered into a protection of business agreement on
the closing date of the Merger (the "Protection of Business Agreement"), which
prohibits Security Capital and its affiliates from providing, anywhere in the
United States, directly or indirectly, substantially the same services as
those previously provided by the REIT Manager and SCG Realty Services to any
entity that owns or operates multifamily communities. The Protection of
Business Agreement does not prohibit Security Capital or its affiliates from
owning the securities of any class of PTR or ATLANTIC. The Protection of
Business Agreement will terminate in the event of an acquisition, directly or
indirectly (other than by purchase from Security Capital or any of its
affiliates), by any person (or group of persons acting in concert), other than
Security Capital or any of its affiliates, of the greater of (i) 25% or more
of the outstanding shares of voting securities of PTR and (ii) the percentage
of outstanding voting securities of PTR owned directly or indirectly by
Security Capital and its affiliates, in either case without the prior written
consent of the Board. Subject to earlier termination pursuant to the preceding
sentence, the Protection of Business Agreement will terminate on September 9,
2000, the third anniversary of the closing date of the Merger.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  Upon consummation of the Merger transaction, the former officers and
employees of the REIT Manager and SCG Realty Services (except C. Ronald
Blankenship and Jeffrey A. Klopf) became officers and employees of PTR who are
compensated for their services by PTR. The following table sets forth the
compensation for the Chief Executive Officer and the four other most highly
compensated executive officers of PTR (the "Named Executive Officers") who
became employees of PTR and for all executive officers as a group (who became
employees of PTR) for 1996. All compensation for 1996 was paid by Security
Capital.

  For 1997, each Named Executive Officer remained an employee of the REIT
Manager and was compensated by Security Capital until the closing of the
Merger, at which time he became an employee of PTR who is compensated by PTR.
For 1997, each Named Executive Officer will receive a salary and be eligible
for a target bonus. The actual amount of the bonus (which may be higher or
lower than the target bonus) will be determined by the Compensation Committee
at the end of the year and will be based on several factors, including
individual performance, PTR's performance, PTR's financial condition,
competitive conditions in the real estate industry and recommendations of
senior management. PTR will continue the same compensation arrangements for
the portion of 1997 in which the Named Executive Officers are employees of
PTR. The Named Executive Officers will be paid the following salaries for 1997
and will be eligible for the following target bonuses for 1997:

(1) Non-qualified options with dividend equivalent units and vesting schedule
    of 25% exercisable on the second anniversary and an additional 25% on each
    of the third, fourth and fifth anniversaries of the date of grant.
(2) Represents the maximum amount of Common Shares which may be purchased by
    participants pursuant to the 1997 grant made under the Incentive Plan.
    Includes shares which may be purchased plus matching options for two
    shares granted with respect to each Common Share purchased.
 
  In addition to the awards under the Incentive Plan, options will be granted
to 50 officers of PTR to purchase an aggregate of $7,442,500 of shares of
Class A Stock of Security Capital (based on the exercise price).
 
  The Board also adopted a 401(k) plan which permits eligible employees to
make pre-tax contributions of up to $9,500 to the plan or such other amount as
may be permitted under Section 401(k) of the Internal Revenue Code of 1986, as
amended (the "Code"). PTR will match 50% of participants' contributions that
do not exceed 6% of their compensation. PTR intends to make such matching
contributions in the form of Common Shares. Participants will become vested in
the matching contributions 20% per each year of service. Former employees of
the REIT Manager and SCG Realty Services will be credited for service for the
time they were employees of Security Capital.
 
LONG-TERM INCENTIVE PLAN
 
 General
 
  The Board has adopted, and PTR's shareholders have approved, the 1997
Incentive Plan (the "Incentive Plan") which authorizes the establishment of
one or more option programs and share purchase programs and the award of share
grants. No more than 5,650,000 Common Shares in the aggregate may be awarded
under the Incentive Plan and no individual may be granted awards with respect
to more than 500,000 Common Shares in any one-year period. The Compensation
Committee of the Board (the "Compensation Committee") will administer the
Incentive Plan. Subject to the terms of the Incentive Plan, the Compensation
Committee determines which employees will be eligible to receive awards under
the Incentive Plan, and the amount, price, timing and other terms and
conditions applicable to such awards. Non-employee Trustees are not eligible
to
 
                                     S-20
<PAGE>
 
participate in the Incentive Plan. All employees of PTR or any of its
subsidiaries are eligible to participate in the Incentive Plan.
 
  Options awarded under the Incentive Plan may be either incentive share
options or non-qualified share options. Options become exercisable and expire
in accordance with the terms established by the Compensation Committee. Common
Shares transferred to a participant pursuant to the exercise of an option may
be subject to such additional restrictions or limitations as the Compensation
Committee may determine. The Incentive Plan provides generally that
participants who are awarded options will also receive dividend equivalent
units with respect to the options. The dividend equivalent units will be
subject to the same vesting schedule as the options and will be payable when
the options are exercised, unless the participant elects to defer receipt, or
expire. Each dividend equivalent unit also accumulates additional dividend
equivalent units on an annual basis. All dividend equivalent units are paid in
the form of Common Shares at the rate of one Common Share per dividend
equivalent unit.
 
  The Incentive Plan provides that the Compensation Committee may award
participants performance stock, subject to achievement of performance
objectives. The number of Common Shares and the performance measures and
periods will be established by the Compensation Committee at the time the
award is made, provided that any performance period will be at least one year.
 
 Non-Qualified Options
 
  Concurrently with the consummation of the Merger transaction, the Named
Executive Officers and other officers and employees of PTR were granted
options to purchase Common Shares at $22 1/16 per Common Share, the average of
the high and low sale prices of the Common Shares on September 8, 1997, the
date the Incentive Plan was approved by PTR's shareholders. The participants
have no rights as shareholders with respect to the Common Shares subject to
their options until the option is exercised. PTR ordinarily will be entitled
to claim a federal income tax deduction on account of the exercise of a non-
qualified option and payment of dividend equivalent units. The amount of the
deduction is equal to the ordinary income recognized by a participant.
 
 Share Purchase Program
 
  Concurrently with the consummation of the Merger transaction, PTR permitted
the Named Executive Officers and other officers and employees to purchase up
to a total of $22,750,000 of Common Shares at $22 1/16 per Common Share, the
average of the high and low sale prices of the Common Shares on September 8,
1997, the date the Incentive Plan was approved by PTR's shareholders, with two
matching options for each Common Share purchased. Each matching option has a
subscription price equal to $22 1/16 per Common Share, the average of the high
and low sale prices of the Common Shares on September 8, 1997. No dividend
equivalent units will be issued with respect to such matching options. The
Common Share purchases provide for a one-year restricted period during which
the participants may not, while employed, sell the Common Shares. If a
participant leaves the employment of PTR prior to the end of the restricted
period, PTR has the right to repurchase the Common Shares at the fair market
value of such Common Shares at the time the participant's employment is
terminated. At the end of the restricted period, the participant will own the
Common Shares without further restriction. However, if the participant sells
the Common Shares after the end of the restricted period, the participant's
matching options may be adversely affected. PTR made loans for up to 95% of
the purchase price available to participants. Each loan is full recourse to
the participant and is secured by the purchased Common Shares.

    Merger on PTR. Upon consummation of the Merger, an expense of this nature
    will be recorded as an operating expense on PTR's statement of earnings,
    but PTR will not deduct the expense for purposes of calculating funds from
    operations, due to the non-recurring and non-cash nature of the expense.
    See "Management's Discussion and Analysis of Financial Condition and
    Results of Operations--REIT Management Agreement."
(2) Represents non-cash amortization associated with the Homestead Note
    conversion feature and warrant-related deferred revenue which is not
    recognized for purposes of funds from operations.
(3) Funds from operations represents net earnings computed in accordance with
    GAAP, excluding gains (or losses) from real estate transactions,
    provisions for possible losses, extraordinary items, significant non-
    recurring items and real estate depreciation. PTR believes that funds from
    operations is helpful to a reader as a measure of the performance of an
    equity REIT because, along with cash flow from operating activities,
    financing activities and investing activities, it provides a reader with
    an indication of the ability of PTR to incur and service debt, to make
    capital expenditures 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 PTR's operating
    performance or as an alternative to cash flows from operating, investing
    or financing activities as a measure of liquidity. In June 1994, PTR
    adopted the National Association of Real Estate Investment Trusts'
    ("NAREIT") revised definition of funds from operations. Under this more
    conservative definition, loan cost amortization is not added back to net
    earnings in determining funds from operations. For comparability, funds
    from operations for the periods prior to July 1994 give effect to the
    revised definition. The funds from operations measure presented by PTR,
    while consistent with the NAREIT definition, will not be comparable to
    similarly titled measures of other REITs 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 presented above under "Operations
    Summary".

  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                  OPERATIONS
 
  The following information should be read in conjunction with PTR's financial
statements and notes thereto incorporated by reference herein.
 
  The statements contained in this discussion and elsewhere in this Prospectus
Supplement and the accompanying Prospectus that are not historical facts are
forward-looking statements within the meaning of Section 27A of the Securities
Act and Section 21E of the Exchange Act. These forward-looking statements are
based on current expectations, estimates and projections about the industry
and markets in which PTR operates, management's beliefs and assumptions made
by management. Words such as "expects," "anticipates," "intends," "plans,"
"believes," "seeks," "estimates" and variations of such words and similar
expressions are intended to identify such forward-looking statements. These
statements are not guarantees of future performance and involve certain risks,
uncertainties and assumptions which are difficult to predict. Therefore,
actual outcomes and results may differ materially from what is expressed or
forecasted in such forward-looking statements. PTR's operating results depend
primarily on income from multifamily communities, which is substantially
influenced by (i) the demand for and supply of multifamily units in PTR's
primary target market and submarkets, (ii) operating expense levels, (iii) the
effectiveness of property-level operations and (iv) the pace and price at
which PTR can acquire and develop additional multifamily communities. Capital
and credit market conditions which affect PTR's cost of capital also influence
operating results.
 
OVERVIEW
 
 General
 
  PTR's results of operations, financial position and liquidity have been
influenced primarily by the operations of and investments made in PTR's
multifamily communities. The term "multifamily" as used herein refers to
garden-style communities and excludes Homestead Village(R) extended-stay
lodging assets, which were contributed to a new publicly traded company,
Homestead, on October 17, 1996, in exchange for certain Homestead securities.

Current Development Activity
 
  PTR believes that development of multifamily communities from the ground up,
which are built for long-term ownership and designed to meet broad resident
preferences and demographic trends, will continue to provide an important
source of long-term cash flow growth. PTR believes its ability to compete is
significantly enhanced relative to other companies because of PTR's depth of
development and acquisition

personnel and presence in local markets combined with its access to investment
capital. The following table summarizes PTR's development communities under
construction as of June 30, 1997 (dollar amounts in thousands):

(1) Represents total budgeted development cost, which includes the cost of
    land, fees, permits, payments to contractors, materials, architectural and
    engineering fees and interest and property taxes to be capitalized during
    the construction period.
(2) The percentage leased is based on occupied units divided by total number
    of units in the community (completed and under construction).
(3) A development community is considered in "lease-up" once the first units
    are delivered.
(4) Lease-up has not yet commenced.
 
  There are risks associated with PTR's development and construction
activities which include: development and acquisition opportunities explored
may be abandoned; construction costs of a community may exceed original
estimates due to increased material, labor or other expenses, which could make
completion of the community uneconomical; occupancy rates and rents at a newly
completed community are dependent on a number of factors, including market and
general economic conditions, and may not be sufficient to make the community
profitable; financing may not be available on favorable terms for the
development of a community; and construction and lease-up may not be completed
on schedule, resulting in increased debt service expense and construction
costs. Development activities are also subject to risks relating to the
inability to obtain, or delays in obtaining, all necessary land-use, building,
occupancy and other required governmental permits and authorizations. The
occurrence of any of the events described above could adversely affect PTR's
ability to achieve its projected yields on communities under development or
redevelopment.
 
  To mitigate these risks, PTR obtains zoning and municipal approvals prior to
purchasing land. Furthermore, PTR does not take construction risk, but instead
uses qualified third-party general contractors to build its communities, using
guaranteed maximum price contracts. PTR cannot eliminate all development risk,
but believes that the opportunities to better control product and realize
higher returns from development communities compensate for the limited risk.
 
 Recent Acquisitions
 
  In addition to its development activity, during the six month period ended
June 30, 1997, PTR completed the acquisition of 11 operating multifamily
communities (3,717 units) in California and Seattle at a total expected
investment of $331.5 million.
 
  Acquisitions entail risks that investments will fail to perform in
accordance with expectations and that judgments with respect to the cost of
improvements to bring an acquired community up to standards established for
the market position intended for that community will prove inaccurate, as well
as general investment risks associated with any new real estate investment.
Although PTR undertakes an evaluation of the physical condition of each new
community before it is acquired, certain defects or necessary repairs may not
be detected until after the community is acquired, which could significantly
increase PTR's total acquisition costs.
 
                                     S-26
<PAGE>
 
  These risks are partially mitigated and managed by the extensive market
research and rigorous due diligence process performed in connection with every
community considered. These factors combined with PTR's extensive market
experience throughout its target market and methodical approval process have
proven PTR's ability to select investments that have a high probability of
meeting or exceeding underwritten expectations.
 
RESULTS OF OPERATIONS
 
 Six Months Ended June 30, 1997 compared to June 30, 1996
 
  Net earnings for the six months ended June 30, 1997 and 1996 were $80.5
million and $54.6 million, respectively, an increase of $25.9 million (47.4%).
This increase resulted primarily from a $29.1 million increase in gains on
dispositions and increased earnings from multifamily communities offset by the
elimination of earnings from Homestead Village properties and higher interest
expense. A discussion of the major components of the increase in net earnings
follows.

  The following table summarizes the Net Operating Income generated from
property operations for each period (in thousands):

(1) Net Operating Income is defined as rental revenues less rental expenses,
    real estate taxes and property management fees.
 
  At June 30, 1997, multifamily investments comprised 99.2% of PTR's total
real estate portfolio, based on total expected investment. The overall $15.0
million increase in Net Operating Income from PTR's multifamily communities
for the six months ended June 30, 1997 as compared to the six months ended
June 30, 1996 was attributable to a $20.8 million increase in rental revenues
partially offset by a $5.8 million increase in rental expenses, real estate
taxes and property management fees ("Operating Expenses"). The $20.8 million
increase in rental revenues from $138.8 million for the six months ended June
30, 1996 to $159.6 million for the six months ended June 30, 1997 was
primarily attributable to increases in rental revenues generated by existing
multifamily communities, increased investments in newer markets such as
California, and dispositions in markets with lower rental rates such as Tucson
and Phoenix. Similarly, the $5.8 million increase in Operating Expenses from
$54.3 million for the six months ended June 30, 1996 to $60.1 million for the
six months ended June 30, 1997 is attributable primarily to higher operating
costs in new markets and increases in Operating Expenses associated with
existing multifamily communities. Even with these higher operating costs,
PTR's multifamily net operating income as a percentage of rental revenues
increased from 60.8% in 1996 to 62.4% in 1997 due to the significant revenue
increases. Additional information for these communities is presented below
under "--Same Store Communities".
 
  PTR categorizes operating multifamily communities (which include all
communities not under development) 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 75.6% and 82.8% of
PTR's operating multifamily portfolio was classified as stabilized as of June
30, 1997 and 1996, respectively, based on total expected investment.
 
                                     S-27
<PAGE>
 
  The $7.6 million in Homestead Village Net Operating Income shown for the six
months ended June 30, 1996 resulted from rental revenues aggregating $14.9
million offset by Operating Expenses aggregating $7.3 million generated from
26 properties operating as of June 30, 1996. The decrease in Net Operating
Income related to the Homestead Village(R) properties in the six months ended
June 30, 1997 is entirely due to the contribution of all properties to
Homestead, a newly formed company, on October 17, 1996.

 Homestead Interest and Homestead Notes
 
  Through June 30, 1997, PTR had funded $142.4 million of its $198.8 million
Homestead funding commitment of which $41.3 million was funded during the six
months ended June 30, 1997. This leaves a remaining commitment under the
funding commitment agreement of approximately $56.4 million, which will be
provided to Homestead throughout the remainder of 1997 and early 1998 to fund
developments as needed on development properties contributed by PTR.
 
  During the six months ended June 30, 1997, PTR recorded $7.0 million in
interest income ($6.4 million for purposes of calculating funds from
operations) from the Homestead Notes. PTR deducts from net earnings the
 
                                     S-29
<PAGE>
 
interest income related to the amortization of discounts and warrant-related
deferred revenue in calculating funds from operations. Homestead interest
income is expected to increase in future periods as PTR continues to fund
Homestead's development activity up to its $198.8 million funding commitment.
 
  Upon full funding, PTR will have funded $198.8 million in exchange for
Homestead Notes having a face amount of $221.3 million. The Homestead Notes
are convertible into Homestead common stock after March 31, 1997 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 June 30,
1997 of $17.875, PTR's ownership would result in the following incremental
value per PTR Common Share at June 30, 1997 (in thousands, except per share
amounts:)

  Upon full funding of the Homestead Notes by PTR and ATLANTIC, PTR's
conversion rights would represent a 34.7% ownership interest in Homestead.
This ownership interest assumes no further equity offerings by Homestead,
conversion of all Homestead Notes by PTR and ATLANTIC and exercise of all
outstanding Homestead warrants.
 
 Depreciation Expense
 
  The increase in depreciation expense resulted primarily from the increase in
the number of operating communities partially offset by dispositions,
including those related to the contribution of assets to Homestead on October
17, 1996.
 
 Interest Expense
 
  The following table summarizes PTR's interest expense (in thousands):

</TABLE>
 
  Interest expense on PTR's credit facilities increased $3.1 million (73.6%)
resulting primarily from higher average outstanding balances. Average
borrowings on the line of credit were approximately $117.2 millon (with an
average effective interest rate of 8.3%) during the six months ended June 30,
1997, as compared to average borrowings of approximately $94.2 million (with
an average effective interest rate of 7.55%) for the same period in 1996.
 
  Interest expense on PTR's long-term unsecured debt ("Long Term Debt")
increased $11.5 million (103.2%) for the six month period ended June 30, 1997
as compared to the same period in 1996. The increase is primarily attributable
to the issuance of $380 million of Long-Term Debt during the year-ended
December 31, 1996 and $50 million of Long-Term Debt in March 1997.
 
                                     S-30
<PAGE>
 
  Mortgage interest expense increased approximately $2.7 million (44.6%) for
the six months ended June 30, 1997 as compared with the same period in 1996.
This increase is the result of additional weighted-average debt outstanding
due to mortgage assumptions related to community acquisitions which were
partially offset by prepayments during 1996 and 1997.
 
  The increase in interest costs were partially offset by an increase of
approximately $1.2 million (16.5%) in capitalized interest. The increase in
capitalized interest is attributable to higher levels of multifamily
development activity for the six months ended June 30, 1997 as compared to the
same period in 1996.
 
 REIT Management Fee Paid to Affiliate
 
  The REIT Management fee paid by PTR decreased by approximately 17.3% during
the six months ended June 30, 1997 as compared to the same period in 1996.
This decrease is primarily attributable to an overall increase in the assumed
principal amortization and interest on Long-Term Debt for purposes of the fee
calculation, coupled with the fact that interest income on the Homestead Notes
has been excluded from the calculation of the fee in accordance with the terms
of the agreement.
 
  On June 10, 1997, the Board extended the term of the REIT Management
Agreement through the earlier of (i) the date of the consummation of the
Merger, or (ii) the regularly scheduled Board meeting in the fourth quarter of
1997. See "The Merger Transaction" for information regarding the Merger
whereby PTR acquired the operations and businesses of the REIT Manager and SCG
Realty Services in exchange for Common Shares.
 
 Gains and Provision for Possible Loss on Investments
 
  As a result of PTR's asset optimization strategy, PTR disposed of 23
multifamily communities, one industrial building and two parcels of land
during the six months ended June 30, 1997, representing gross proceeds of
$249.8 million. As of June 30, 1997, PTR held a portion of the 1997
disposition proceeds aggregating $19.7 million in an interest bearing escrow
account, pending acquisition of other multifamily communities to complete the
tax-deferred exchange. During the six months ended June 30, 1996, PTR disposed
of six multifamily communities, one parcel of land and one industrial building
representing gross proceeds of $87.8 million. The proceeds from the 1996 and
1997 dispositions have been or will be redeployed into other multifamily
communities that in PTR's view offer better long-term cash flow growth
prospects. For financial reporting purposes, however, the transactions
qualified for profit recognition, and aggregate gains of $37.2 million and
$8.1 million, were recorded for the six months ended June 30, 1997 and 1996,
respectively.
 
  As part of PTR's asset optimization strategy, six multifamily communities
and five parcels of land and one industrial building were held for disposition
as of June 30, 1997. The aggregate carrying value of properties held for
disposition was approximately $79.0 million at June 30, 1997. Subject to
normal closing risks, PTR expects to complete the disposition of these
communities during 1997 and early 1998 and redeploy the net proceeds from such
dispositions, where appropriate, through tax-deferred exchanges, into the
acquisition of multifamily communities.
 
 Three Month Period Ended June 30, 1997 and 1996
 
  Revenues and expenses for the three months ended June 30, 1997 compared to
the three months ended June 30, 1996 reflect changes similar to those
discussed in the preceding paragraphs for the comparison of the six months
ended on the same dates. The changes are substantially attributable to the
same reasons discussed in the preceding paragraphs for the six months ended
June 30, 1997 and 1996.
 
ENVIRONMENTAL MATTERS
 
  PTR is subject to environmental regulations related to the ownership,
operation, development and acquisition of real estate. As part of its due
diligence procedures, PTR has conducted Phase I environmental assessments on
each community prior to acquisition. The cost of complying with environmental
regulations was not material to PTR's results of operations during either
period. PTR is not aware of any environmental condition on any of its
communities that is likely to have a material adverse effect on PTR's
financial position or results of operations.
 
                                     S-31
<PAGE>
 
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 adequate to meet
PTR's operating and capital investment requirements as well as its Homestead
funding obligation and shareholder distribution requirements.
 
 Operating Activities
 
  Net cash flow provided by operating activities increased by $10.0 million
(16.6%) for the six months ended June 30, 1997 as compared to the same period
in 1996. This increase was due primarily to increased cash generated by
multifamily communities and reduced cash outflows for operating assets and
liabilities resulting from timing differences.
 
 Investing and Financing Activities
 
  During the six months ended June 30, 1997 and 1996, PTR invested cash of
$371.3 and $284.0 million, respectively, in real estate investments relating
primarily to the significant acquisition and development activity summarized
in "--Overview" above. The $371.3 million invested in real estate and $41.3
million in fundings of Homestead Notes during the six months ended June 30,
1997 were financed primarily from $224.5 million in net proceeds from property
dispositions (excluding $19.7 million held in escrow pending tax-deferred
exchanges), and borrowings under PTR's credit facilities which were partially
repaid from proceeds related to PTR's $50 million offering of Long-Term Debt
issued in March 1997 and $54.3 million in net proceeds from the sale of 2.5
million Common Shares in June 1997. The $284.0 million invested during the six
months ended June 30, 1996 was financed primarily from $85.7 million in net
proceeds from property dispositions and borrowings under PTR's credit
facilities which were partially repaid from proceeds related to PTR's $150
million offering of Long-Term Debt issued in February 1996. Total mortgage
debt assumed during 1997 in connection with community acquisitions aggregated
$82.8 million.
 
  Other significant financing activity included the payment of $59.5 million
and $57.6 million in Common Share and preferred share distributions for the
six months ended June 30, 1997 and 1996, respectively. The increase is
primarily attributable to a 4.8% increase in the distributions paid per Common
Share. Preferred Share dividends decreased approximately $2.9 million during
the respective periods as a result of conversions of Series A Preferred Shares
to Common Shares which resulted in increased Common Share distributions. PTR
prepaid mortgages due to community dispositions of $19.9 million and $25.8
million for the six months ended June 30, 1997 and 1996, respectively.
 
 Credit Facilities
 
  PTR has a $350 million unsecured revolving line of credit with TCB, as agent
for a group of financial institutions (collectively, the "Lenders"). The line
of credit 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 September 8, 1997) or the federal
funds rate plus 0.50%, or at PTR"s option, LIBOR (5.6875% at September 8,
1997) plus 0.75% (6.4375% at September 8, 1997). 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 Debt. Additionally, there is a commitment fee on the average
unfunded line of credit balance. The commitment fee was $114,000 and $218,000
for the six months ended June 30, 1997 and 1996, respectively.

  At September 8, 1997, there were $151.3 million of borrowings outstanding
under PTR's line of credit.
 
  On September 9, 1996, PTR entered into a short-term, unsecured, borrowing
agreement with TCB. The loan matures March 18, 1998 and bears interest at an
overnight rate which ranged from 5.94% to 7.00% during the six months ended
June 30, 1997. At September 8, 1997, there were $14.3 million of borrowings
outstanding under this agreement.
 
  On March 10, 1997, PTR borrowed $60 million under a short-term unsecured
borrowing agreement with a financial institution. The loan matures on
September 10, 1997. Interest is payable monthly at an annual rate of LIBOR
plus 0.60% (6.2563% at September 8, 1997). On April 4, 1997, PTR borrowed an
additional $40 million under a short-term unsecured borrowing agreement with
the same financial institution, having approximately the same interest rate
and repayment terms. The proceeds from both loans were used to repay
borrowings under PTR's line of credit.
 
  The aggregate amount of borrowings outstanding under all of PTR's credit
facilities at September 8, 1997 was $265.5 million.
 
 Long-Term Debt
 
  At August 31, 1997, PTR had issued a total of $630 million of Long-Term
Debt, which bears interest at fixed rates, payable semi-annually. Funds from
such issuances were used primarily for acquisition, development and renovation
of multifamily communities and to repay balances on credit facilities incurred
for such purposes. The following table summarizes the Long-Term Debt as of
August 31, 1997:

  The Long-Term Debt together with PTR's mortgages payable result in a
relatively level amortization schedule which minimizes PTR's refinancing risk.
The Long-Term Debt, other than a $15 million tranche of 6.500% Notes issued
October 21, 1996 and due 2026 (the "6.500% Notes"), is redeemable at any time
at the option of PTR, in whole or in part, at a redemption price equal to the
sum of the principal amount of the Long-Term Debt being redeemed plus accrued
interest thereon to the redemption date plus an adjustment, if any, based
 
                                     S-33
<PAGE>
 
on the yield to maturity relating to market yields available at redemption.
The 6.500% Notes may be repaid on October 15, 1999 at the option of the
holders at their full principal amount together with accrued interest. If the
holders do not exercise their right to require PTR to repay the 6.500% Notes
on October 15, 1999, they may be repaid at the option of PTR, in whole or in
part, at a redemption price equal to the sum of the principal amount of the
Long-Term Debt being redeemed plus accrued interest thereon to the redemption
date plus an adjustment, if any, based on the yield to maturity relating to
market yields available at redemption. The Long-Term Debt is governed by the
terms and provisions of an indenture agreement.

 Covenants
 
  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 covenants pertaining to its debt instruments at June 30,
1997.
 
                                     S-34
<PAGE>
 
 Commitments and Contingencies
 
  At June 30, 1997, PTR had contingent contracts or letters of intent, subject
to PTR's final due diligence and approval of all entitlements, to acquire land
for new development communities with an estimated 6,602 multifamily units at a
total development cost of approximately $612.7 million. At the same date, PTR
also had contingent contracts or letters of intent, subject to final due
diligence, for the acquisition of 328 additional operating multifamily units
with a total expected investment of $17.5 million, including budgeted
renovations. At June 30, 1997, PTR had unfunded development commitments for
developments under construction of $180.4 million. For a description of
unfunded commitments in connection with the Homestead Notes see "--Results of
Operations--Homestead Interest and Homestead Notes".
 
  PTR expects to finance these activities and other future investment and
operating needs with cash on hand, borrowings under its credit facilities and
disposition proceeds from its asset optimization strategy, prior to arranging
long-term capital. The credit facilities should 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 $170.9 million (assuming the sale of all
Common Shares offered in this Offering) in shelf-registered securities which
can be issued 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 37.70% at June 30, 1997, on a historical basis
and 34.85% at June 30, 1997, as adjusted to give effect to the Merger, and to
the Rights Offering and this Offering (assuming the sale of all Common Shares
in this Offering) and the application of the net proceeds therefrom, provides
considerable flexibility with respect to its ability to finance its investment
activities.
 
  From time to time, PTR utilizes derivative financial instruments as hedges
in anticipation of future debt offerings in order to manage well-defined
interest rate risk. In anticipation of the $50 million Long-Term Debt offering
that closed March 31, 1997, PTR entered into interest rate contracts with
notional amounts aggregating $50 million in 1996. Upon completion of the
offering, PTR terminated the interest rate contracts, realizing a gain of
approximately $819,000 which has been deferred and is being amortized as an
offset to interest expense over the term of the Long-Term Debt that was
issued. During August 1997, PTR entered into interest rate contracts with
notional amounts aggregating $60 million in anticipation of a long-term debt
offering expected to close within the next six months.
 
 Distributions
 
  PTR paid first, second and third quarter 1997 distributions of $0.325 per
Common Share on February 20, May 29, and August 27, 1997. On March 31 and June
30, 1997, PTR paid quarterly dividends on the Series A Preferred Shares of
$0.4377425 per share and quarterly dividends on its Series B Cumulative
Redeemable Preferred Shares of Beneficial Interest (the "Series B Preferred
Shares") of $0.5625 per share.
 
 Funds From Operations
 
  Funds from operations is defined as net earnings computed in accordance with
GAAP, excluding gains (or losses) from real estate transactions, provisions
for possible losses on extraordinary items significant non-recurring items and
real estate depreciation. PTR believes that funds from operations is helpful
to a reader as a measure of the performance of an equity REIT because, along
with cash flow from operating activities, financing activities and investing
activities, it provides a reader with an indication of the ability of PTR to
incur and service debt, to make capital expenditures 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 PTR's
operating performance or as an alternative to cash flows from operating,
investing, or financing activities as a measure of liquidity. In June 1994,
PTR adopted NAREIT's revised definition of funds from operations. Under this
more conservative definition, loan cost amortization is not added back to net
earnings in determining funds from operations. The funds from operations
measure presented by PTR, while consistent with the NAREIT definition, will
not be comparable to similarly titled measures of other REITs 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 distribution paid to shareholders are described above under "--Results of
Operations--Distributions".
 
                                     S-35
<PAGE>
 
  In 1996, PTR contributed its Homestead Village extended-stay lodging assets
to Homestead. Management believes that funds from operations for the six
months ended June 30, 1996 should be adjusted to reflect the effects of the
Homestead transaction to provide a more meaningful comparison to the
historical 1997 results. Accordingly, pro forma funds from operations for the
six months ended June 30, 1996 has been calculated as if the Homestead
transaction had occurred on January 1, 1996. The funds from operations
information is unaudited and the pro forma funds from operations is not
necessarily indicative of what actual funds from operations would have been if
the Homestead transaction had occurred on January 1, 1996.
 
  Funds from operations and pro forma funds from operations (1996) are as

REIT MANAGEMENT AGREEMENT
 
  Effective March 1, 1991, PTR entered into a REIT management agreement (the
"REIT Management Agreement") with the REIT Manager pursuant to which the REIT
Manager assumed day-to-day management of PTR. Between March 1, 1991 and
September 9, 1997, the REIT Manager provided both strategic and day-to-day
 
                                     S-36
<PAGE>
 
management of PTR, including research, investment analysis, acquisition,
development, dispositions, property management, capital markets, legal,
accounting and other administrative services. The REIT Manager was a wholly
owned subsidiary of Security Capital, which owned approximately 34.0% of the
Common Shares at August 31, 1997.
 
  The REIT Management Agreement required PTR to pay a base annual fee of
$855,000 plus 16% of cash flow as defined in the REIT Management Agreement in
excess of $4,837,000, payable monthly. In the REIT Management Agreement, cash
flow was calculated by reference to PTR's cash flow from operations plus (i)
fees paid to the REIT Manager, (ii) extraordinary expenses incurred at the
request of the independent Trustees of PTR and (iii) 33% of any interest paid
by PTR on convertible subordinated debentures (of which there has been none
since inception of the REIT Management Agreement); and after deducting (i)
regularly scheduled principal payments (excluding prepayments or balloon
payments) for debt with commercially reasonable amortization schedules, (ii)
actual or assumed principal and interest payments on Long-Term Debt, (iii)
interest income received in connection with the Homestead Notes and (iv)
distributions actually paid with respect to any nonconvertible preferred
shares of beneficial interest of PTR. The REIT Management Agreement provided
that Long-Term Debt was treated as if it had regularly scheduled principal and
interest payments similar to a 20-year, level monthly payment, fully
amortizing mortgage, with the assumed principal and interest payments deducted
from cash flow in determining the fee. Cash flow did not include dividend and
interest income from PTR Development Services, realized gains or losses from
dispositions of investments or income from cash equivalent investments. The
REIT Manager also received a fee of 0.25% per year on the average daily
balance of cash equivalent investments.
 
  As PTR arranged additional Long-Term Debt and nonconvertible preferred share
financing and as additional funding of Homestead Notes occurred, the REIT
Management fee effectively declined in proportion to PTR's earnings from
operations. This decline resulted from the fact that actual or assumed
regularly scheduled principal payments associated with Long-Term Debt and
distributions actually paid with respect to nonconvertible preferred shares
were deducted from the cash flow amount on which the REIT Management fee was
based. Similarly, interest income from the Homestead Notes was not included in
the cash flow amount in determining the REIT Management fee.
 
  PTR was obligated to reimburse the REIT Manager for certain expenses
incurred by the REIT Manager on behalf of PTR relating to PTR's operations,
consisting primarily of external professional fees, offering costs and travel
expenses.
 
  The REIT Management Agreement was renewable by PTR annually, subject to a
determination by the independent Trustees (who received performance benchmark
information verified by an independent third party) that the REIT Manager's
performance was satisfactory and that the compensation payable to the REIT
Manager was fair. Each of PTR and the REIT Manager was entitled to terminate
the REIT Management Agreement on 60 days' notice.
 
  On September 9, 1997, pursuant to the Merger Agreement, Security Capital
caused the REIT Manager and SCG Realty Services to be merged into a newly
formed subsidiary of PTR. The REIT Management Agreement was terminated on
September 9, 1997 upon closing of the Merger. As a result of the Merger, the
employees of the REIT Manager and SCG Realty Services have become employees of
PTR. The market value of the 3,295,533 Common Shares issued to Security
Capital on the Merger date was approximately $73 million, based on the closing
price of the Common Shares on such date of $22 1/4, of which approximately $3
million will be allocated to the net tangible assets acquired and the $70
million difference will be accounted for as costs incurred in acquiring the
management companies from a related party since the management companies do
not qualify as "businesses" for purposes of applying APB Opinion No. 16
"Business Combinations". This one-time adjustment will be recorded as an
operating expense on PTR's statement of earnings but PTR will not deduct this
expense for purposes of calculating funds from operations, due to the non-
recurring and non-cash nature of this expense. See "The Merger Transaction"
for a more complete description of the Merger.

<PAGE>
 
                                  MANAGEMENT
 
  As a result of the Merger, which was consummated on September 9, 1997, PTR
became a fully integrated operating company. PTR has approximately 259
professionals dedicated to implementing its highly focused operating and
investment strategy. See "The Merger Transaction" for a description of the
Merger whereby Security Capital caused the REIT Manager and SCG Realty
Services to merge into a newly formed subsidiary of PTR in exchange for Common
Shares.
 
  PTR has organized itself such that each operating professional specializes
in a particular discipline (such as research, marketing, development,
acquisition, due diligence, dispositions, property management, capital markets
or financial operations) rather than being responsible for all functions on a
project-by-project basis. All investments are approved by PTR's management
investment committee, using uniform criteria, prior to being submitted to the
investment committee of the Board. Additionally, regional operating
professionals focus on specific target markets to ensure high levels of
attention to resident services. PTR believes that the quality of management
should be assessed in light of the factors discussed below.
 
  Management Depth/Succession. PTR believes that management should have
several senior executives with the leadership, operational, investment and
financial skills and experience to oversee the entire operations of the REIT.
PTR believes that several of its senior officers could serve as the principal
executive officer and continue PTR's performance. See "--Trustees and Officers
of PTR."
 
  Strategic Vision and Research Capability. PTR believes that management
should have the strategic vision to determine an investment focus that
provides both favorable initial yields and strong long-term growth prospects.
To identify favorable investment opportunities, PTR relies heavily on the
strong research capabilities of Security Capital Real Estate Research. PTR and
its affiliates have several persons, who work closely with the senior officers
of PTR, devoting substantial time to research on a submarket-by-submarket
basis. This research is dedicated to new multifamily investment opportunities
as well as new products such as the Homestead Village(R) extended-stay lodging
product, which resulted in the spin-off of Homestead in November 1996.
 
  Investment Committee Process. PTR believes that an investment committee
should provide discipline and guidance to the investment activities of the
REIT in order to achieve its investment goals. The five members of PTR's
management investment committee have a combined 77 years of experience in the
real estate industry. The investment committee receives detailed written
analyses and research, in a standardized format, from PTR's personnel and
evaluates all prospective investments pursuant to uniform underwriting
criteria prior to submission of investment recommendations to the investment
committee of the Board. The quality of PTR's investment committee process is
demonstrated by PTR's ability to achieve its investment goals and generally
exceed its projected initial returns and cash flow growth from PTR's
multifamily investments.
 
  Development/Redevelopment and Acquisition Capability. PTR believes that by
internally developing projects and redeveloping well located existing
communities, management can create value for the REIT that normally escapes
through sales premiums paid to successful developers. PTR's personnel have
substantial development and redevelopment experience, as described in "--
Trustees and Officers of PTR." PTR has 32 full-time professionals committed to
development and acquisition activities. This team has arranged for
approximately $2.1 billion of successful acquisitions and has developed or
commenced development of multifamily communities with a budgeted development
cost of approximately $1.2 billion for PTR from March 1991 through June 30,
1997, based on total expected investment. At June 30, 1997, PTR had 9,778
multifamily units under construction or in planning and owned, with a total
budgeted development cost of $642.7 million. In addition, as of the same date,
PTR had contingent contracts or letters of intent, subject to PTR's final due
diligence and approval of all entitlements, to acquire land for the
development of an estimated 6,602 multifamily units with a total budgeted

  Disposition Capability. The ability to identify and effectively complete the
cost-effective disposition of targeted communities is essential to the
successful execution of PTR's investment strategy. Since PTR's asset
optimization program began in December 1995 and through June 30, 1997, PTR had
completed the disposition of 12,835 multifamily units, realizing aggregate
gains of $77.2 million on aggregate gross proceeds of $549.4 million, which
were redeployed, typically on a tax-deferred basis, into strategic
acquisitions.
 
  Due Diligence Process. PTR believes that management should have experienced
senior personnel dedicated to performing comprehensive due diligence. PTR has
nine full-time due diligence professionals and has developed uniform systems
and procedures for due diligence. PTR's due diligence personnel have analyzed
and screened over $4.0 billion of investments.
 
  Operating Capability. PTR believes that management can substantially improve
funds from operations by actively and effectively managing its multifamily
communities. PTR and its affiliates have devoted substantial personnel and
financial resources to develop value-added operating systems, which control
and effectively administer the management of PTR's multifamily portfolio.
 
  Capital Markets Capability. PTR believes that management must be able to
effectively raise capital for the REIT in order for the REIT to achieve growth
through investment. PTR and its affiliate, Capital Markets Group, have
arranged for funding of over $2.0 billion from securities offerings of debt
and equity securities and have arranged for credit facilities including an
unsecured $350 million line of credit for PTR. These credit facilities provide
PTR with the financial flexibility to take advantage of attractive investment
opportunities prior to raising capital through securities offerings.
 
  Communications/Shareholders Relations Capability. PTR believes that a REIT's
success in capital markets and investment activities can be enhanced by
management's ability to effectively communicate the REIT's strategy and
performance to investors, sellers of property and the financial media. PTR has
access to full-time personnel who prepare informational materials for and
conduct periodic meetings with the investment community and analysts.
 
  PTR believes that successfully combining the foregoing attributes
significantly enhances a REIT's ability to increase cash flow and the market
valuation of the REIT's portfolio.

Act. In connection with the Rights Offering, Security Capital agreed to pay a
fee of $250,000 to Capital Markets Group.
 
                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
  The following is a summary of certain federal income tax matters of general
application pertaining to the holding and disposing of Common Shares under the
Code. This discussion is general in nature and is not exhaustive of all
possible tax considerations, nor does the discussion address any state, local
or foreign tax considerations. The discussion is based on current law, is for
general information only, and is not tax advice. This discussion does not
purport to deal with all aspects of federal income taxation that may be
relevant to particular shareholders in light of their personal investment or
tax circumstances, or to certain types of shareholders (including insurance
companies, tax exempt organizations, financial institutions or broker dealers,
foreign corporations and persons who are not citizens or residents of the
United States) subject to special treatment under the federal income tax laws.
PTR has not requested and will not request a ruling from the IRS with respect
to any of the federal income tax issues discussed below.
 
  This Prospectus Supplement does not address the taxation of PTR or the
impact on PTR of its election to be taxed as a REIT. Such matters are
addressed in the accompanying Prospectus under "Federal Income Tax
Considerations--Taxation of PTR". Prospective investors should consult, and
must depend on, their own tax advisors regarding the state, local, foreign and
other tax consequences of holding and disposing of Common Shares.
 
  For a discussion regarding the taxation of dividends and other
distributions, see "Federal Income Tax Considerations--Taxation of PTR's
Shareholders" in the accompanying Prospectus.

  For a discussion of backup withholding, see "Federal Income Tax
Considerations--Other Tax Considerations--Backup Withholding" in the
accompanying Prospectus.
 
  Upon the sale or exchange of Common Shares to a party other than PTR, a
holder of Common Shares will realize a capital gain or loss measured by the
difference between the amount realized on the sale or other disposition and
the holder's adjusted tax basis in the Common Shares (provided the Common
Shares are held as a capital asset). Such gain or loss will be a long term
capital gain or loss if the holder's holding period with respect to the Common
Shares is more than one year at the time of the sale or exchange. Further, any
loss on a sale of Common Shares which were held by the holder for six months
or less and with respect to which a capital gain dividend was received will be
treated as a long term capital loss, up to the amount of the capital gain
dividend received with respect to such shares.
 
TAX CONSIDERATIONS REGARDING THE MERGER
 
 General
 
  The following discussion summarizes the material U.S. federal income tax
considerations of the Merger and the Warrant Issuance to PTR and its
shareholders. The following discussion is based upon the current provisions of
the Code, its legislative history, administrative pronouncements, judicial
decisions and Treasury regulations, all of which are subject to change,
possibly with retroactive effect. The following discussion does not purport to
be a complete discussion of all U.S. federal income tax considerations. The
following discussion does not address the tax consequences of the Merger and
the Warrant Issuance under state, local or non-U.S. tax laws. In addition, the
following discussion may not apply, in whole or in part, to particular
categories of PTR shareholders, such as dealers in securities, insurance
companies, foreign persons, financial institutions and tax-exempt
organizations (except with regard to "unrelated business taxable income"). THE
FOLLOWING DISCUSSION IS INCLUDED FOR GENERAL INFORMATION ONLY. ALL PTR
SHAREHOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS TO DETERMINE THE SPECIFIC
TAX CONSEQUENCES OF THE MERGER OR WARRANT ISSUANCE, INCLUDING ANY STATE, LOCAL
AND NON-U.S. TAX CONSEQUENCES.
 
 The Merger
 
  In the opinion of Mayer, Brown & Platt, based on certain representations of
Security Capital and PTR , the Merger is properly treated for federal income
tax purposes as a reorganization within the meaning of Section 368(a) of the
Code. Accordingly, PTR did not recognize income, gain or loss upon the
consummation of the Merger (assuming that PTR makes the election described
under "--Built-in Gain Rules" below). In addition, the Merger did not result
in a taxable event to the PTR shareholders. Nonetheless, such opinion is not
binding on the IRS nor will it preclude the IRS from adopting a contrary
position. Moreover, since no ruling from the IRS was or will be sought with
respect to the federal income tax consequences of the Merger, there can be no
complete assurance that the IRS will agree with the conclusions set forth
herein. The discussion below assumes that the Merger is treated as a
reorganization within the meaning of Section 368(a) of the Code.
 
  Basis and Holding Period. The assets formerly held by the REIT Manager and
SCG Realty Services have the same adjusted tax basis in the hands of PTR as
they had in the hands of the REIT Manager and SCG Realty Services immediately
prior to the closing date of the Merger. The holding period for each of the
assets of the REIT Manager and SCG Realty Services in the hands of PTR
includes the period each asset was held by the REIT Manager and SCG Realty
Services immediately prior to the closing date of the Merger.
 
  Built-in Gain Rules. Under the "Built-in Gain Rules" of IRS Notice 88-19,
1988-1 C.B. 486, PTR will be subject to a corporate level tax if it disposes
of any of the assets acquired from Security Capital in the Merger at any time
during the 10-year period beginning on the closing date of the Merger (the
"Restriction Period"). This tax would be imposed on PTR at the top regular
corporate rate (currently 35%) in effect at the time of the
 
                                     S-46
<PAGE>
 
disposition on the excess of (i) the lesser of (a) the fair market value on
the closing date of the assets disposed of or (b) the selling price of such
assets over (ii) PTR's adjusted basis on the closing date in such assets (such
excess being referred to as the "Built-in Gain"). PTR currently does not
intend to dispose of any of the assets acquired in the Merger during the
Restriction Period, but there can be no assurance that one or more of such
dispositions will not occur. The results described above with respect to the
recognition of Built-in Gain assume that PTR will make the appropriate
election pursuant to the Built-in Gain Rules or applicable future
administrative rules or Treasury regulations. Under the Merger Agreement, PTR
covenanted to make this election.
 
  Liability for Other Taxes. Pursuant to the Merger Agreement, Security
Capital is responsible for income tax liabilities attributable to the
operations of the REIT Manager and SCG Realty Services through the
consummation of the Merger. However, PTR, as successor to the REIT Manager and
SCG Realty Services in the Merger, is severally liable (together with Security
Capital and the members of its "affiliated group" within the meaning of
Section 1502 of the Code) for income tax liabilities of Security Capital and
the members of its "affiliated group" for periods prior to and including the
year in which the consummation of the Merger occurred. Security Capital,
however, agreed to indemnify and hold harmless PTR from and against any income
tax liabilities of the REIT Manager and SCG Realty Services for all periods
prior to the closing date of the Merger and any income tax liabilities of
Security Capital and the members of its "affiliated group".
 
  Consequences of the Merger on PTR's Qualification as a REIT. In light of the
unique federal income tax requirements applicable to REITs, the Merger could
have adverse consequences on PTR's continued qualification as a REIT. In the
opinion of Mayer, Brown & Platt, based upon certain representations of
Security Capital and PTR, the consummation of the Merger will not jeopardize
the status of PTR as a REIT under the Code.
 
 The Warrant Issuance
 
  Receipt of Warrants. Pursuant to the Warrant Issuance, (i) a shareholder
will have ordinary income upon receipt of a warrant in an amount equal to the
fair market value of the warrants received on the issuance date, (ii) a
shareholder's tax basis in the warrants received will equal the fair market
value of the warrants received on the issuance date and (iii) a shareholder's
holding period for the warrants received will begin on the issuance date.
 
  Fractional Warrants. If a shareholder receives cash in lieu of a fractional
warrant, such shareholder will recognize gain or loss measured by the
difference between the tax basis of such fractional warrant (i.e. the fair
market value of such fractional warrant on the issuance date) and the amount
of cash received. Such gain or loss will constitute capital gain or loss if
the shareholder holds the warrants as a capital asset on the issuance date,
and will be short-term capital gain or loss since the holding period for such
fractional warrants will be less than one year.
 
  Disposition of Shares Prior to the Warrant Issuance Record Date. While a
shareholder generally would not recognize ordinary income on the disposition
of his or her Common Shares, a shareholder disposing of his or her Common
Shares on or after the closing date of the Merger and prior to the record date
for the Warrant Issuance may recognize ordinary income in an amount equal to
the fair market value of the right of a holder of the Common Shares to receive
the warrants, measured as of the time of disposition of the Common Shares. A
shareholder would not be able to offset any portion of such ordinary income
with his or her tax basis in his or her Common Shares. To the extent a
shareholder recognizes ordinary income, the amount realized for purposes of
calculating capital gain or loss on such disposition will be reduced by the
amount of such ordinary income.
 
  Tax-Exempt Shareholders. Section 511 of the Code imposes on organizations
exempt from federal income tax under Section 501(a) of the Code a tax at
corporate income tax rates on such organizations' "unrelated business taxable
income." In the opinion of Mayer, Brown & Platt, the receipt by tax-exempt
shareholders of PTR of the warrants pursuant to the Warrant Issuance will be
treated as unrelated business taxable income.
 
                                     S-47
<PAGE>
 
  Backup Withholding. Under the backup withholding rules of the Code (which
generally impose a 31% withholding tax on certain persons who fail to furnish
the information required under the United States tax reporting requirements),
a PTR shareholder may be subject to backup withholding with respect to the
receipt of the warrants unless such shareholder (i) is a corporation or comes
within certain other exempt categories and, when required, demonstrates this
fact or (ii) provides a correct taxpayer identification number and certifies
under penalties of perjury that the taxpayer identification number is correct
and that the holder is not currently subject to backup withholding because of
a failure to report all dividend and interest income. Any amount withheld
under these rules will be credited against the shareholder's Federal income
tax liability.
 
  Information Reporting. Security Capital is required to report to the PTR
shareholders receiving warrants and the IRS the value of the warrants issued
pursuant to the Warrant Issuance on Form 1099-MISC.
 
  Sale, Disposition, Exercise or Expiration of Warrants. In general, upon a
sale or other disposition of a warrant, a holder of warrants will recognize
gain or loss measured by the difference between the amount realized on the
sale or other disposition and the warrant holder's tax basis in the warrant.
In general, such gain or loss will be a capital gain or loss if the stock into
which the warrants are exercisable would be a capital asset in the warrant
holder's hands and will be a short-term capital gain or loss because the
warrants will expire in one year from the date of issuance.
 
  Exercise of Warrants. Except as discussed below with respect to cash
received in lieu of fractional Class B Stock, a warrant holder will not
recognize gain or loss upon the exercise of a warrant. A warrant holder's tax
basis in the Class B Stock received upon exercise of a warrant will be equal
to the sum of (1) the warrant holder's tax basis in the warrant exercised and
(2) the exercise price paid. The holding period of the Class B Stock received
upon the exercise of a warrant will begin on the date of exercise. Holders
receiving cash in lieu of fractional Class B Stock upon exercise of a warrant
will recognize gain to the extent that the cash received exceeds the warrant
holder's tax basis in the portion of the warrant exercised for cash in lieu of
fractional Class B Stock.
 
  Expiration of the Warrants. If a warrant holder's warrants expire without
being exercised, the warrant holder will recognize a loss equal to its tax
basis in the expired warrants. In general, such loss will be a capital loss if
the stock into which the warrants were exercisable would be a capital asset in
the warrant holder's hands and will be a short-term loss because the warrants
will expire in one year from the date of issuance.
 
  Adjustment of Conversion Ratio. The terms of the warrants distributed
pursuant to the Merger Agreement provide for adjustment of the price for
exercise if Security Capital makes certain distributions of stock, cash or
other property to its shareholders. While Security Capital does not presently
contemplate making such a distribution, if Security Capital makes a
distribution of cash or property resulting in an adjustment to the exercise
price, the holders of the warrants may be viewed as receiving a "deemed
distribution" under Section 305 of the Code, even if such warrant holder does
not hold any Class B Stock at such time. The deemed distribution would
constitute a taxable dividend, taxable as ordinary income, to the extent that
the earnings and profits of Security Capital were allocable to the deemed
distribution. The amount of the deemed distribution which exceeded the
allocated earnings and profits of Security Capital would be considered a
return of capital, and would reduce the warrant holder's tax basis in the
warrants (but not below zero) by the value of the deemed distribution. To the
extent that the value of the deemed distribution exceeds the warrant holder's
tax basis in its warrants, the deemed distribution would result in gain to
such warrant holder. In any event, the warrant holder's tax basis in its
warrants would then immediately be increased by the value of the property
deemed to have been distributed.
 
OTHER TAX CONSIDERATIONS
 
 Possible Legislative or Other Actions Affecting Tax Consequences
 
  Prospective shareholders should recognize that the present federal income
tax treatment of an investment in PTR may be modified by legislative, judicial
or administrative action at any time and that any such action may affect
investments and commitments previously made. The rules dealing with federal
income taxation are
 
                                     S-48
<PAGE>
 
constantly under review by persons involved in the legislative process and by
the IRS and the Treasury, resulting in revisions of regulations and revised
interpretations of established concepts as well as statutory changes.
Revisions in federal tax laws and interpretations thereof could adversely
affect the tax consequences of an investment in PTR.
 
 State and Local Taxes
 
  PTR and its shareholders may be subject to state or local taxation in
various jurisdictions, including those in which it or they transact business
or reside. The state and local tax treatment of PTR and its shareholders may
not conform to the federal income tax consequences discussed above.
Consequently, prospective shareholders should consult their own tax advisors
regarding the effect of state and local tax laws on an investment in the
Common Shares of PTR.
 
  EACH PROSPECTIVE PURCHASER IS ADVISED TO CONSULT WITH HIS OR HER OWN TAX
ADVISOR REGARDING THE SPECIFIC TAX CONSEQUENCES TO HIM OR HER OF THE PURCHASE,
OWNERSHIP AND SALE OF SHARES IN AN ENTITY ELECTING TO BE TAXED AS A REAL

                        SECURITY CAPITAL PACIFIC TRUST
 
  PTR's objective is to be the preeminent real estate operating company
focusing on the development, acquisition, operation and long-term ownership of
multifamily communities in its western United States target market. As a
result of the merger of Security Capital Pacific Incorporated and SCG Realty
Services Incorporated into a wholly-owned subsidiary of PTR on September 9,
1997, PTR is a fully integrated operating company with 259 professionals
dedicated to implementing its highly focused operating and investment
strategy.
 
  PTR seeks to achieve long-term sustainable growth in cash flow by maximizing
the operating performance of its core portfolio through value-added operating
systems and concentrating its highly experienced team of professionals on
developing and acquiring industry-leading product in targeted submarkets.
These submarkets are identified by proprietary research as exhibiting strong
job growth and favorable demographic trends.
 
  PTR's investment strategy is focused on three principal components: (i) the
development of state-of-the-art new communities targeted primarily at one of
the largest segments of the renter market, moderate income households; (ii)
the acquisition of multifamily communities exhibiting high cash flow growth
potential or attractive redevelopment opportunities; and (iii) the execution
of its asset optimization strategy, which involves the disposition of
properties which no longer meet PTR's investment objectives and the
redeployment of the proceeds, typically on a tax-deferred basis, into assets
that in PTR's view offer better long-term cash flow growth prospects.
 
  PTR was organized in 1963 as a real estate investment trust under the laws
of Maryland. Its principal executive offices are located at 7670 South Chester
Street, Suite 100, Englewood, Colorado 80112, and its telephone number is
(303) 708-5959.
 
                                USE OF PROCEEDS
 
  Unless otherwise described in the applicable Prospectus Supplement, the net
proceeds from the sale of the Offered Securities will be used for the
development and acquisition of additional multifamily communities, as suitable
opportunities arise, for the repayment of certain outstanding indebtedness at
such time and for working capital purposes.
 
                               RATIO INFORMATION
 
  For the purpose of computing these ratios, (a) "earnings" consist of
earnings from operations plus fixed charges other than capitalized interest
and (b) "fixed charges" consist of interest on borrowed funds (including
capitalized interest) and amortization of debt discount and expense.

                        DESCRIPTION OF DEBT SECURITIES
 
  The Debt Securities are to be issued under an Indenture, dated as of
February 1, 1994, as supplemented by the First Supplemental Indenture, dated
as of February 2, 1994 (as so supplemented, the "Indenture"), between PTR and
State Street Bank and Trust Company (the "Trustee"). The Indenture has been
incorporated by reference as an exhibit to the Registration Statement of which
this Prospectus is a part and is available for inspection at the corporate
trust office of the Trustee at 225 Franklin Street, Boston, Massachusetts
02110 or as described below under "Available Information." The Indenture is
subject to, and governed by, the Trust Indenture Act of 1939, as amended (the
"TIA"). The statements made hereunder relating to the Indenture and the Debt
Securities to be issued thereunder are summaries of certain provisions
thereof, do not purport to be complete and are subject to, and are qualified
in their entirety by reference to, all provisions of the Indenture and such
Debt Securities. All section references appearing herein are to sections of
the Indenture, and capitalized terms used but not defined herein shall have
the respective meanings set forth in the Indenture.
 
GENERAL
 
  The Debt Securities will be direct, unsecured obligations of PTR and will
rank equally with all other unsecured and unsubordinated indebtedness of PTR.
The Indenture provides that the Debt Securities may be issued without limit as
to aggregate principal amount, in one or more series, in each case as
established from time to time in or pursuant to authority granted by a
resolution of PTR's Board of Trustees (the "Board") or as established in one
or more indentures supplemental to the Indenture. All Debt Securities of one
series need not be issued at the same time and, unless otherwise provided, a
series may be reopened, without the consent of the Holders of the Debt
Securities of such series, for issuances of additional Debt Securities of such
series (Section 301).
 
  The Indenture provides that there may be more than one Trustee thereunder,
each with respect to one or more series of Debt Securities. Any Trustee under
the Indenture may resign or be removed with respect to one or more series of
Debt Securities, and a successor Trustee may be appointed to act with respect
to such series (Section 608). In the event that two or more persons are acting
as Trustee with respect to different series of Debt Securities, each such
Trustee shall be a Trustee of a trust under the Indenture separate and apart
from the trust administered by any other Trustee (Sections 101 and 609), and,
except as otherwise indicated herein, any action described herein to be taken
by the Trustee may be taken by each such Trustee with respect to, and only
with respect to, the one or more series of Debt Securities for which it is
Trustee under the Indenture.
 
  Reference is made to the Prospectus Supplement relating to the series of
Debt Securities being offered for the specific terms thereof, including:
 
    (1) the title of such series of Debt Securities;
 
    (2) the aggregate principal amount of such series of Debt Securities and
  any limit on such principal amount;
 
    (3) the percentage of the principal amount at which the Debt Securities
  of such series will be issued and, if other than the full principal amount
  thereof, the portion of the principal amount thereof payable upon
  declaration of acceleration of the maturity thereof, or the method by which
  any such portion shall be determined;
 
    (4) the date or dates, or the method by which such date or dates will be
  determined, on which the principal of such Debt Securities will be payable
  and the amount of principal payable thereon;
 
    (5) the rate or rates (which may be fixed or variable), or the method by
  which such rate or rates shall be determined, at which such Debt Securities
  will bear interest, if any;
 
    (6) the date or dates, or the method by which such date or dates will be
  determined, from which any such interest will accrue, the Interest Payment
  Dates on which any such interest will be payable, the Regular Record Dates
  for such Interest Payment Dates, or the method by which such dates shall be
  determined, the Person to whom, and the manner in which, such interest
  shall be payable, and the basis upon which interest shall be calculated if
  other than that of a 360-day year comprised of twelve 30-day months;
 
                                       3

    (7) the place or places where the principal of (and premium or Make-Whole
  Amount (as defined), if any) and interest and Additional Amounts, if any,
  on the Debt Securities of such series will be payable, where such Debt
  Securities may be surrendered for registration of transfer or exchange and
  where notices or demands to or upon PTR in respect of such Debt Securities
  and the Indenture may be served;
 
    (8) the period or periods within which, the price or prices (including
  the premium or Make-Whole Amount, if any) at which, the currency or
  currencies in which, and the other terms and conditions upon which the Debt
  Securities of such series may be redeemed, as a whole or in part, at the
  option of PTR, if PTR is to have such an option;
 
    (9) the obligation, if any, of PTR to redeem, repay or purchase the Debt
  Securities of such series pursuant to any sinking fund or analogous
  provision or at the option of a Holder thereof, and the period or periods
  within which, the date or dates upon which, the price or prices at which,
  the currency or currencies, currency unit or units or composite currency or
  currencies in which, and the other terms and conditions upon which such
  Debt Securities shall be redeemed, repaid or purchased, as a whole or in
  part, pursuant to such obligation;
 
    (10) if other than United States dollars, the currency or currencies in
  which the Debt Securities of such series are denominated and payable, which
  may be a foreign currency or units of two or more foreign currencies or a
  composite currency or currencies, and the terms and conditions relating
  thereto;
 
    (11) whether the amount of payments of principal of (and premium or Make-
  Whole Amount, if any) or interest, if any, on the Debt Securities of such
  series may be determined with reference to an index, formula or other
  method (which index, formula or method may be, but need not be, based on a
  currency or currencies, currency unit or units or composite currency or
  currencies) and the manner in which such amounts shall be determined;
 
    (12) whether the principal of (and premium or Make-Whole Amount, if any)
  or interest or Additional Amounts, if any, on the Debt Securities of such
  series are to be payable, at the election of PTR or a Holder, in a currency
  or currencies, currency unit or units or composite currency or currencies,
  other than that in which such Debt Securities are denominated or stated to
  be payable, the period or periods within which, and the terms and
  conditions upon which, such election may be made, and the time and manner
  of, and identity of the exchange rate agent with responsibility for,
  determining the exchange rate between the currency or currencies in which
  such Debt Securities are denominated or stated to be payable and the
  currency or currencies in which such Debt Securities are to be so payable;
 
    (13) any additions to, modifications of or deletions from the terms of
  such series of Debt Securities with respect to the Events of Default or
  covenants set forth in the Indenture;
 
    (14) whether the Debt Securities of such series will be issued in
  certificated or book-entry form;
 
    (15) whether the Debt Securities of such series will be in registered or
  bearer form and, if in registered form, the denominations thereof if other
  than $1,000 and any integral multiple thereof and, if in bearer form, the
  denominations thereof if other than $5,000 and the terms and conditions
  relating thereto;
 
    (16) the applicability, if any, of the defeasance and covenant defeasance

  respect of any tax, assessment or governmental charge and, if so, whether
  PTR will have the option to redeem such Debt Securities in lieu of making
  such payment; and
 
    (19) any other terms of such series of Debt Securities not inconsistent
  with the provisions of the Indenture (Section 301).
 
                                       4

  The Debt Securities may provide for less than the entire principal amount
thereof to be payable upon declaration of acceleration of the maturity thereof
or bear no interest or bear interest at a rate which at the time of issuance
is below market rates ("Original Issue Discount Securities"). Special United
States federal income tax, accounting and other considerations applicable to
Original Issue Discount Securities will be described in the applicable
Prospectus Supplement.
 
  Under the Indenture, PTR will have the ability, in addition to the ability
to issue Debt Securities with terms different from those of Debt Securities
previously issued, without the consent of the Holders, to reopen a previous
issue of a series of Debt Securities and issue additional Debt Securities of
such series.
 
  Except as set forth below under "Certain Covenants--Limitations on
Incurrence of Debt," the Indenture does not contain any other provisions that
would limit the ability of PTR to incur indebtedness or that would afford
Holders of Debt Securities protection in the event of a highly leveraged or
similar transaction involving PTR or in the event of a change of control of
PTR. However, PTR's Restated Declaration of Trust, as amended and supplemented
(the "Declaration of Trust"), restricts beneficial ownership of PTR's
outstanding Common Shares by a single person, or persons acting as a group, to
9.8% of such Common Shares, with certain exceptions (including an exception
for the ownership of up to 49% of such Common Shares in the case of Security
Capital Group Incorporated ("Security Capital")). See "Description of Common
Shares--Restriction on Size of Holdings." Additionally, the Articles
Supplementary relating to PTR's Cumulative Convertible Series A Preferred
Shares of Beneficial Interest, par value $1.00 per share (the "Series A
Preferred Shares") and PTR's Series B Cumulative Redeemable Preferred Shares
of Beneficial Interest, par value $1.00 per share (the "Series B Preferred
Shares") restrict beneficial ownership of the Series A Preferred Shares and
Series B Preferred Shares, respectively, by a person, or persons acting as a
group, to 25% of the Series A Preferred Shares or Series B Preferred Shares,
as the case may be. Similarly, the Articles Supplementary for each series of
Preferred Shares will contain certain provisions restricting the ownership and
transfer of the Preferred Shares. See "Description of Preferred Shares--
Restrictions on Ownership." These restrictions are designed to preserve PTR's
status as a REIT and, therefore, may act to prevent or hinder a change of
control. Reference is made to the applicable Prospectus Supplement for
information with respect to any deletions from, modifications of or additions
to the Events of Default or covenants of PTR that are described below,
including any addition of a covenant or other provision providing event risk
or similar protection.
 
DENOMINATIONS, INTEREST, REGISTRATION AND TRANSFER
 
  Unless otherwise described in the applicable Prospectus Supplement, the Debt
Securities of any series issued in registered form will be issuable in
denominations of $1,000 and integral multiples thereof. Unless otherwise
described in the applicable Prospectus Supplement, the Debt Securities of any
series issued in bearer form will be issuable in denominations of $5,000
(Section 302).
 
  Unless otherwise specified in the applicable Prospectus Supplement, the
principal of (and premium or Make-Whole Amount, if any) and interest on any
series of Debt Securities will be payable at the corporate trust office of the
Trustee, initially located at 225 Franklin Street, Boston, Massachusetts
02110; provided that, at the option of PTR, payment of interest may be made by
check mailed to the address of the Person entitled thereto as it appears in
the Security Register or by wire transfer of funds to such Person to an
account maintained within the United States (Sections 301, 305, 306, 307 and
1002).
 
  If any Interest Payment Date, Principal Payment Date or the Maturity Date
falls on a day that is not a Business Day, the required payment shall be made
on the next Business Day as if it were made on the date such payment was due
and no interest shall accrue on the amount so payable for the period from and
after such Interest Payment Date, Principal Payment Date or the Maturity Date,
as the case may be. "Business Day" means any day, other than a Saturday or
Sunday, on which banks in Boston, Massachusetts are not required or authorized
by law or executive order to close. Any interest not punctually paid or duly
provided for on any Interest Payment Date with respect to a Debt Security
("Defaulted Interest") will forthwith cease to be payable to the Holder on the
applicable Regular Record Date and either may be paid to the person in whose
name such Debt Security is registered at the close of business on a special
record date (the "Special Record Date") for the payment of such
 
                                       5
<PAGE>
 
Defaulted Interest to be fixed by the Trustee, notice of which shall be given
to the Holder of such Debt Security not less than 10 days prior to such
Special Record Date, or may be paid at any time in any other lawful manner,
all as more completely described in the Indenture (Section 307).
 
  Subject to certain limitations imposed upon Debt Securities issued in book-
entry form, the Debt Securities of any series will be exchangeable for other
Debt Securities of the same series and of a like aggregate principal amount
and tenor of different authorized denominations upon surrender of such Debt
Securities at the corporate trust office of the Trustee referred to above. In
addition, subject to certain limitations imposed upon Debt Securities issued
in book-entry form, the Debt Securities of any series may be surrendered for
registration of transfer thereof at the corporate trust office of the Trustee
referred to above. Every Debt Security surrendered for registration of
transfer or exchange shall be duly endorsed or accompanied by a written
instrument of transfer. No service charge will be made for any registration of
transfer or exchange of any Debt Securities, but PTR may require payment of a
sum sufficient to cover any tax or other governmental charge payable in
connection therewith (Section 305). If the applicable Prospectus Supplement
refers to any transfer agent (in addition to the Trustee) initially designated
by PTR with respect to any series of Debt Securities, PTR may at any time
rescind the designation of any such transfer agent or approve a change in the
location at which any such transfer agent acts, except that PTR will be
required to maintain a transfer agent in each Place of Payment for such
series. PTR may at any time designate additional transfer agents with respect
to any series of Debt Securities (Section 1002).
 
  Neither PTR nor the Trustee shall be required to (i) issue, register the
transfer of or exchange Debt Securities of any series during a period
beginning at the opening of business 15 days before any selection of Debt
Securities of that series to be redeemed and ending at the close of business
on the day of mailing of the relevant notice of redemption; (ii) register the
transfer of or exchange any Debt Security, or portion thereof, called for
redemption, except the unredeemed portion of any Debt Security being redeemed
in part; or (iii) issue, register the transfer of or exchange any Debt
Security which has been surrendered for repayment at the option of the Holder,
except the portion, if any, of such Debt Security not to be so repaid (Section
305).
 
MERGER, CONSOLIDATION OR SALE
 
  PTR may consolidate with, or sell, lease or convey all or substantially all
of its assets to, or merge with or into, any other entity, provided that (a)
either PTR shall be the continuing entity, or the successor entity (if other
than PTR) formed by or resulting from any such consolidation or merger or
which shall have received the transfer of such assets is a Person organized
and existing under the laws of the United States or any State thereof and
shall expressly assume payment of the principal of (and premium or Make-Whole
Amount, if any) and any interest (including Additional Amounts, if any) on all
of the Debt Securities and the due and punctual performance and observance of
all of the covenants and conditions contained in the Indenture; (b)
immediately after giving effect to such transaction and treating any
indebtedness which becomes an obligation of PTR or any Subsidiary as a result
thereof as having been incurred by PTR or such Subsidiary at the time of such
transaction, no Event of Default under the Indenture, and no event which,
after notice or the lapse of time, or both, would become such an Event of
Default, shall have occurred and be continuing; and (c) an officer's
certificate and legal opinion covering such conditions shall be delivered to
the Trustee (Sections 801 and 803).
 
CERTAIN COVENANTS
 
  Limitations on Incurrence of Debt. PTR will not, and will not permit any
Subsidiary to, incur any Debt (as defined below) if, immediately after giving
effect to the incurrence of such additional Debt and the application of the
proceeds thereof, the aggregate principal amount of all outstanding Debt of
PTR and its Subsidiaries on a consolidated basis determined in accordance with
generally accepted accounting principles is greater than 60% of the sum of
(without duplication) (i) PTR's Total Assets (as defined below) as of the end
of the calendar quarter covered in PTR's Annual Report on Form 10-K or
Quarterly Report on Form 10-Q, as the case may be, most recently filed with
the Securities and Exchange Commission (the "Commission") (or, if such filing
is not permitted under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), with the Trustee) prior to the incurrence of such additional
Debt and (ii) the purchase price of any real estate assets or mortgages
 
                                       6
<PAGE>
 
receivable acquired, and the amount of any securities offering proceeds
received (to the extent that such proceeds were not used to acquire real
estate assets or mortgages receivable or used to reduce Debt), by PTR or any
Subsidiary since the end of such calendar quarter, including those proceeds
obtained in connection with the incurrence of such additional Debt (Section
1004).
 
  In addition to the foregoing limitation on the incurrence of Debt, PTR will
not, and will not permit any Subsidiary to, incur any Debt secured by any
mortgage, lien, charge, pledge, encumbrance or security interest of any kind
upon any of the property of PTR or any Subsidiary if, immediately after giving
effect to the incurrence of such additional Debt and the application of the
proceeds thereof, the aggregate principal amount of all outstanding Debt of
PTR and its Subsidiaries on a consolidated basis which is secured by any
mortgage, lien, charge, pledge, encumbrance or security interest on property
of PTR or any Subsidiary is greater than 40% of PTR's Total Assets (Section
1004).
 
  In addition to the foregoing limitations on the incurrence of Debt, PTR will
not, and will not permit any Subsidiary to, incur any Debt if the ratio of
Consolidated Income Available for Debt Service (as defined below) to the
Annual Service Charge (as defined below) for the four consecutive fiscal
quarters most recently ended prior to the date on which such additional Debt
is to be incurred shall have been less than 1.5:1, on a pro forma basis after
giving effect thereto and to the application of the proceeds therefrom, and
calculated on the assumption that (i) such Debt and any other Debt incurred by
PTR and its Subsidiaries since the first day of such four-quarter period and
the application of the proceeds therefrom, including to refinance other Debt,
had occurred at the beginning of such period; (ii) the repayment or retirement
of any other Debt by PTR and its Subsidiaries since the first day of such
four-quarter period had been incurred, repaid or retired at the beginning of
such period (except that, in making such computation, the amount of Debt under
any revolving credit facility shall be computed based upon the average daily
balance of such Debt during such period); (iii) in the case of Acquired Debt
(as defined below) or Debt incurred in connection with any acquisition since
the first day of such four-quarter period, the related acquisition had
occurred as of the first day of such period with the appropriate adjustments
with respect to such acquisition being included in such pro forma calculation;
and (iv) in the case of any acquisition or disposition by PTR or its
Subsidiaries of any asset or group of assets since the first day of such four-
quarter period, whether by merger, stock purchase or sale, or asset purchase
or sale, such acquisition or disposition or any related repayment of Debt had
occurred as of the first day of such period with the appropriate adjustments
with respect to such acquisition or disposition being included in such pro
forma calculation (Section 1004).
 
  Existence. Except as permitted under "--Merger, Consolidation or Sale," PTR
will do or cause to be done all things necessary to preserve and keep in full
force and effect its existence, rights (charter and statutory) and franchises;
provided, however, that PTR shall not be required to preserve any right or
franchise if it determines that the preservation thereof is no longer
desirable in the conduct of its business and that the loss thereof is not
disadvantageous in any material respect to the Holders of the Debt Securities
(Section 1005).
 
  Maintenance of Properties. PTR will cause all of its properties used or
useful in the conduct of its business or the business of any Subsidiary to be
maintained and kept in good condition, repair and working order and supplied
with all necessary equipment and will cause to be made all necessary repairs,
renewals, replacements, betterments and improvements thereof, all as in the
judgment of PTR may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that PTR and its Subsidiaries shall not be prevented from selling or
otherwise disposing for value its properties in the ordinary course of
business (Section 1006).
 
  Insurance. PTR will, and will cause each of its Subsidiaries to, keep all of
its insurable properties insured against loss or damage at least equal to
their then full insurable value with financially sound and reputable insurance
companies (Section 1007).
 
  Payment of Taxes and Other Claims. PTR will pay or discharge or cause to be
paid or discharged, before the same shall become delinquent, (i) all taxes,
assessments and governmental charges levied or imposed upon it or any
Subsidiary or upon the income, profits or property of PTR or any Subsidiary
and (ii) all lawful claims for
 
                                       7
<PAGE>
 
labor, materials and supplies which, if unpaid, might by law become a lien
upon the property of PTR or any Subsidiary; provided, however, that PTR shall
not be required to pay or discharge or cause to be paid or discharged any such
tax, assessment, charge or claim whose amount, applicability or validity is
being contested in good faith by appropriate proceedings (Section 1008).
 
  Provision of Financial Information. Whether or not PTR is subject to Section
13 or 15(d) of the Exchange Act, PTR will, to the extent permitted under the
Exchange Act, file with the Commission the annual reports, quarterly reports
and other documents which PTR would have been required to file with the
Commission pursuant to such Section 13 and 15(d) (the "Financial Statements")
if PTR were so subject, such documents to be filed with the Commission on or
prior to the respective dates (the "Required Filing Dates") by which PTR would
have been required so to file such documents if PTR were so subject. PTR will
also in any event (i) within 15 days of each Required Filing Date (x) transmit
by mail to all Holders of Debt Securities, as their names and addresses appear
in the Security Register, without cost to such Holders, copies of the annual
reports and quarterly reports which PTR would have been required to file with
the Commission pursuant to Section 13 or 15(d) of the Exchange Act if PTR were
subject to such Sections and (y) file with the Trustee copies of the annual
reports, quarterly reports and other documents which PTR would have been
required to file with the Commission pursuant to Section 13 or 15(d) of the
Exchange Act if PTR were subject to such Sections and (ii) if filing such
documents by PTR with the Commission is not permitted under the Exchange Act,
promptly upon written request and payment of the reasonable cost of
duplication and delivery, supply copies of such documents to any prospective
Holder (Section 1009).

becomes a Subsidiary or (ii) assumed in connection with the acquisition of
assets from such Person, in each case, other than Debt incurred in connection

Sheet in accordance with generally accepted accounting principles, and also
includes, to the extent not otherwise included, any obligation by PTR or any
Subsidiary to be liable for, or to pay, as obligor, guarantor or otherwise
(other than for purposes of collection in the ordinary course of business),

that Debt shall be deemed to be incurred by PTR or any Subsidiary whenever PTR
or such Subsidiary shall create, assume, guarantee or otherwise become liable
in respect thereof).
 
  "Disqualified Stock" means, with respect to any Person, any Capital Stock of

EVENTS OF DEFAULT, NOTICE AND WAIVER
 
  The Indenture provides that the following events are "Events of Default"
with respect to any series of Debt Securities issued thereunder: (i) default
for 30 days in the payment of any installment of interest or Additional
Amounts payable on any Debt Security of such series; (ii) default in the
payment of the principal of (or premium or Make-Whole Amount, if any, on) any
Debt Security of such series at its Maturity; (iii) default in making any
sinking fund payment as required for any Debt Security of such series; (iv)
default in the performance of any other covenant of PTR contained in the
Indenture (other than a covenant added to the Indenture solely for the benefit
of a series of Debt Securities issued thereunder other than such series),
continued for 60 days after written notice as provided in the Indenture; (v)
default in the payment of an aggregate principal amount exceeding $10,000,000
of any evidence of indebtedness of PTR or any mortgage, indenture or other
instrument under which such indebtedness is issued or by which such
indebtedness is secured, such default having occurred after the expiration of
any applicable grace period and having resulted in the acceleration of the
maturity of such indebtedness, but only if such indebtedness is not discharged
or such acceleration is not rescinded or annulled; (vi) the entry by a court
of competent jurisdiction of one or more judgments, orders or decrees against
PTR or any of its Subsidiaries in an aggregate amount (excluding amounts fully
covered by insurance) in excess of
 
                                       9
<PAGE>
 
$10,000,000 and such judgments, orders or decrees remain undischarged,
unstayed and unsatisfied in an aggregate amount (excluding amounts fully
covered by insurance) in excess of $10,000,000 for a period of 30 consecutive
days; (vii) certain events of bankruptcy, insolvency or reorganization, or
court appointment of a receiver, liquidator or trustee of PTR or any
Significant Subsidiary or for all or substantially all of either of its
property; and (viii) any other Event of Default provided with respect to a
particular series of Debt Securities (Section 501). The term "Significant
Subsidiary" means each significant subsidiary (as defined in Regulation S-X
promulgated by the Commission) of PTR.
 
  If an Event of Default under the Indenture with respect to Debt Securities
of any series at the time Outstanding occurs and is continuing, then in every
such case the Trustee or the Holders of not less than 25% in principal amount
of the Outstanding Debt Securities of that series may declare the principal
amount (or, if the Debt Securities of that series are Original Issue Discount
Securities or Indexed Securities, such portion of the principal amount as may
be specified in the terms thereof) of, and the Make-Whole Amount, if any, on,
all of the Debt Securities of that series to be due and payable immediately by
written notice thereof to PTR (and to the Trustee if given by the Holders).
However, at any time after such a declaration of acceleration with respect to
Debt Securities of such series (or of all Debt Securities then Outstanding
under the Indenture, as the case may be) has been made, but before a judgment
or decree for payment of the money due has been obtained by the Trustee, the
Holders of not less than a majority in principal amount of Outstanding Debt
Securities of such series (or of all Debt Securities then Outstanding under
the Indenture, as the case may be) may rescind and annul such declaration and
its consequences if (i) PTR shall have deposited with the Trustee all required
payments of the principal of (and premium or Make-Whole Amount, if any) and
interest, and any Additional Amounts, on the Debt Securities of such series
(or of all Debt Securities then outstanding under the Indenture, as the case
may be), plus certain fees, expenses, disbursements and advances of the
Trustee and (ii) all Events of Default, other than the nonpayment of
accelerated principal (or specified portion thereof and the Make-Whole Amount,
if any) or interest, with respect to Debt Securities of such series (or of all
Debt Securities then Outstanding under the Indenture, as the case may be) have
been cured or waived as provided in the Indenture (Section 502). The Indenture
also provides that the Holders of not less than a majority in principal amount
of the Outstanding Debt Securities of any series (or of all Debt Securities
then Outstanding under the Indenture, as the case may be) may waive any past
default with respect to such series and its consequences, except a default (i)
in the payment of the principal of (or premium or Make-Whole Amount, if any)
or interest or Additional Amounts payable on any Debt Security of such series
or (ii) in respect of a covenant or provision contained in the Indenture that
cannot be modified or amended without the consent of the Holder of each
Outstanding Debt Security affected thereby (Section 513).
 
  The Trustee is required to give notice to the Holders of Debt Securities
within 90 days of a default under the Indenture; provided, however, that the
Trustee may withhold notice to the Holders of any series of Debt Securities of
any default with respect to such series (except a default in the payment of
the principal of (or premium or Make-Whole Amount, if any) or interest or
Additional Amounts payable on any Debt Security of such series or in the
payment of any sinking fund installment in respect of any Debt Security of
such series) if the Responsible Officers of the Trustee consider such
withholding to be in the interest of such Holders (Section 601).
 
  The Indenture provides that no Holders of Debt Securities of any series may
institute any proceedings, judicial or otherwise, with respect to the
Indenture or for any remedy thereunder, except in the case of failure of the
Trustee, for 60 days, to act after it has received a written request to
institute proceedings in respect of an Event of Default from the Holders of
not less than 25% in principal amount of the Outstanding Debt Securities of
such series, as well as an offer of reasonable indemnity (Section 507). This
provision will not prevent, however, any Holder of Debt Securities from
instituting suit for the enforcement of payment of the principal of (and
premium or Make-Whole Amount, if any), interest on, and Additional Amounts
payable with respect to, such Debt Securities at the respective due dates
thereof (Section 508).
 
  Subject to provisions in the Indenture relating to its duties in case of
default, the Trustee is under no obligation to exercise any of its rights or
powers under the Indenture at the request or direction of any Holders
 
                                      10
<PAGE>
 
of any series of Debt Securities then Outstanding under the Indenture, unless
such Holders shall have offered to the Trustee reasonable security or
indemnity (Section 602). The Holders of not less than a majority in principal
amount of the Outstanding Debt Securities of any series (or of all Debt
Securities then Outstanding under the Indenture, as the case may be) shall
have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or of exercising any trust
or power conferred upon the Trustee. However, the Trustee may refuse to follow
any direction which is in conflict with any law or the Indenture, which may
involve the Trustee in personal liability or which may be unduly prejudicial
to the Holders of Debt Securities of such series not joining therein (Section
512).
 
  Within 120 days after the close of each fiscal year, PTR must deliver to the
Trustee a certificate, signed by one of several specified officers, stating
whether or not such officer has knowledge of any default under the Indenture
and, if so, specifying each such default and the nature and status thereof
(Section 1010).
 
MODIFICATION OF THE INDENTURE
 
  Modifications and amendments of the Indenture may be made with the consent
of the Holders of not less than a majority in principal amount of all
Outstanding Debt Securities which are affected by such modification or
amendment; provided, however, that no such modification or amendment may,
without the consent of the Holder of each such Debt Security affected thereby,
(i) change the Stated Maturity of the principal of (or premium or Make-Whole
Amount, if any), or any installment of principal of or interest or Additional
Amounts payable on, any such Debt Security; (ii) reduce the principal amount
of, or the rate or amount of interest on, or any premium or Make-Whole Amount
payable on redemption of, or any Additional Amounts payable with respect to,
any such Debt Security, or reduce the amount of principal of an Original Issue
Discount Security or Make-Whole Amount, if any, that would be due and payable
upon declaration of acceleration of the maturity thereof or would be provable
in bankruptcy, or adversely affect any right of repayment of the Holder of any
such Debt Security; (iii) change the Place of Payment, or the coin or
currency, for payment of principal of (and premium or Make-Whole Amount, if
any), or interest on, or any Additional Amounts payable with respect to, any
such Debt Security; (iv) impair the right to institute suit for the
enforcement of any payment on or with respect to any such Debt Security; (v)
reduce the above-stated percentage of Outstanding Debt Securities of any
series necessary to modify or amend the Indenture, to waive compliance with
certain provisions thereof or certain defaults and consequences thereunder or
to reduce the quorum or voting requirements set forth in the Indenture; or
(vi) modify any of the foregoing provisions or any of the provisions relating
to the waiver of certain past defaults or certain covenants, except to
increase the required percentage to effect such action or to provide that
certain other provisions may not be modified or waived without the consent of
the Holder of such Debt Security (Section 902).
 
  The Holders of not less than a majority in principal amount of Outstanding
Debt Securities have the right to waive compliance by PTR with certain
covenants in the Indenture (Section 1012).
 
  Modifications and amendments of the Indenture may be made by PTR and the
Trustee without the consent of any Holder of Debt Securities for any of the
following purposes: (i) to evidence the succession of another Person to PTR as
obligor under the Indenture; (ii) to add to the covenants of PTR for the
benefit of the Holders of all or any series of Debt Securities or to surrender
any right or power conferred upon PTR in the Indenture; (iii) to add Events of
Default for the benefit of the Holders of all or any series of Debt
Securities; (iv) to add or change any provisions of the Indenture to
facilitate the issuance of, or to liberalize certain terms of, Debt Securities
in bearer form, or to permit or facilitate the issuance of Debt Securities in
uncertificated form, provided that such action shall not adversely affect the
interests of the Holders of the Debt Securities of any series in any material
respect; (v) to change or eliminate any provisions of the Indenture, provided
that any such change or elimination shall become effective only when there are
no Debt Securities Outstanding of any series created prior thereto which are
entitled to the benefit of such provision; (vi) to secure the Debt Securities;
(vii) to establish the form or terms of Debt Securities of any series and any
related coupons; (viii) to provide for the acceptance of appointment by a
successor Trustee or facilitate the administration of the trusts under the
Indenture by more than one Trustee; (ix) to cure any ambiguity, defect or
inconsistency in the Indenture or to make any other
 
                                      11
<PAGE>
 
changes, provided that in each case, such action shall not adversely affect
the interests of Holders of Debt Securities of any series in any material
respect; (x) to close the Indenture with respect to the authentication and
delivery of additional series of Debt Securities or to qualify, or maintain
qualification of, the Indenture under the TIA; or (xi) to supplement any of
the provisions of the Indenture to the extent necessary to permit or
facilitate defeasance and discharge of any series of such Debt Securities,
provided that such action shall not adversely affect the interests of the
Holders of the Debt Securities of any series in any material respect (Section
901).
 
  The Indenture provides that in determining whether the Holders of the
requisite principal amount of Outstanding Debt Securities of a series have
given any request, demand, authorization, direction, notice, consent or waiver
thereunder or whether a quorum is present at a meeting of Holders of Debt
Securities, (i) the principal amount of an Original Issue Discount Security
that shall be deemed to be outstanding shall be the amount of the principal
thereof that would be due and payable as of the date of such determination
upon declaration of acceleration of the maturity thereof; (ii) the principal
amount of a Debt Security denominated in a Foreign Currency that shall be
deemed outstanding shall be the United States dollar equivalent, determined on
the issue date for such Debt Security, of the principal amount (or, in the
case of an Original Issue Discount Security, the United States dollar
equivalent on the issue date of such Debt Security of the amount determined as
provided in (i) above); (iii) the principal amount of an Indexed Security that
shall be deemed outstanding shall be the principal face amount of such Indexed
Security at original issuance, unless otherwise provided with respect to such
Indexed Security pursuant to Section 301 of the Indenture; and (iv) Debt
Securities owned by PTR or any other obligor upon the Debt Securities or any
Affiliate of PTR or of such other obligor shall be disregarded (Section 101).
 
  The Indenture contains provisions for convening meetings of the Holders of
Debt Securities of a series (Section 1501). A meeting may be called at any
time by the Trustee, and also, upon request, by PTR or the Holders of at least
10% in principal amount of the Outstanding Debt Securities of such series, in
any such case upon notice given as provided in the Indenture (Section 1502).
Except for any consent that must be given by the Holder of each Debt Security
affected by certain modifications and amendments of the Indenture, any
resolution presented at a meeting or adjourned meeting duly reconvened at
which a quorum is present may be adopted by the affirmative vote of the
Holders of a majority in principal amount of the Outstanding Debt Securities
of such series; provided, however, that, except as referred to above, any
resolution with respect to any request, demand, authorization, direction,
notice, consent, waiver or other action that may be made, given or taken by
the Holders of a specified percentage, which is less than a majority, in
principal amount of the Outstanding Debt Securities of a series may be adopted
at a meeting or adjourned meeting duly reconvened at which a quorum is present
by the affirmative vote of the Holders of such specified percentage in
principal amount of the Outstanding Debt Securities of that series. Any
resolution passed or decision taken at any meeting of Holders of Debt
Securities of any series duly held in accordance with the Indenture will be
binding on all Holders of Debt Securities of such series. The quorum at any
meeting called to adopt a resolution, and at any reconvened meeting, will be
Persons holding or representing a majority in principal amount of the
Outstanding Debt Securities of a series; provided, however, that if any action
is to be taken at such meeting with respect to a consent or waiver which may
be given by the Holders of not less than a specified percentage in principal
amount of the Outstanding Debt Securities of a series, the Persons holding or
representing such specified percentage in principal amount of the Outstanding
Debt Securities of such series will constitute a quorum (Section 1504).
 
  Notwithstanding the foregoing provisions, if any action is to be taken at a
meeting of Holders of Debt Securities of any series with respect to any
request, demand, authorization, direction, notice, consent, waiver or other
action that the Indenture expressly provides may be made, given or taken by
the Holders of a specified percentage in principal amount of all Outstanding
Debt Securities affected thereby, or of the Holders of such series and one or
more additional series: (i) there shall be no minimum quorum requirement for
such meeting and (ii) the principal amount of the Outstanding Debt Securities
of such series that vote in favor of such request, demand, authorization,
direction, notice, consent, waiver or other action shall be taken into account
in determining whether such request, demand, authorization, direction, notice,
consent, waiver or other action has been made, given or taken under the
Indenture (Section 1504).
 
                                      12
<PAGE>
 
  Any request, demand, authorization, direction, notice, consent, waiver or
other action provided by the Indenture to be given or taken by a specified
percentage in principal amount of the Holders of any or all series of Debt
Securities may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such specified percentage of Holders in
person or by agent duly appointed in writing; and, except as otherwise
expressly provided in the Indenture, such action shall become effective when
such instrument or instruments are delivered to the Trustee. Proof of
execution of any instrument or of a writing appointing any such agent shall be
sufficient for any purpose of the Indenture and (subject to Article Six of the
Indenture) conclusive in favor of the Trustee and PTR, if made in the manner
specified above (Section 1507).
 
DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE
 
  PTR may discharge certain obligations to Holders of any series of Debt
Securities that have not already been delivered to the Trustee for
cancellation and that either have become due and payable or will become due
and payable within one year (or scheduled for redemption within one year) by
irrevocably depositing with the Trustee, in trust, funds in such currency or
currencies, currency unit or units or composite currency or currencies in
which such Debt Securities are payable in an amount sufficient to pay the
entire indebtedness on such Debt Securities in respect of principal (and
premium or Make-Whole Amount, if any) and interest and Additional Amounts
payable to the date of such deposit (if such Debt Securities have become due
and payable) or to the Stated Maturity or Redemption Date, as the case may be
(Section 401).
 
  The Indenture provides that, if the provisions of Article Fourteen are made
applicable to the Debt Securities of or within any series pursuant to Section
301 of the Indenture, PTR may elect either (i) to defease and be discharged
from any and all obligations with respect to such Debt Securities (except for
the obligation to pay Additional Amounts, if any, upon the occurrence of
certain events of tax, assessment or governmental charge with respect to
payments on such Debt Securities and the obligations to register the transfer
or exchange of such Debt Securities, to replace temporary or mutilated,
destroyed, lost or stolen Debt Securities, to maintain an office or agency in
respect of such Debt Securities and to hold moneys for payment in trust)
("defeasance") (Section 1402) or (ii) to be released from its obligations with
respect to such Debt Securities under Sections 1004 to 1009, inclusive, of the
Indenture (being the restrictions described under "--Certain Covenants") and,
if provided pursuant to Section 301 of the Indenture, its obligations with
respect to any other covenant, and any omission to comply with such
obligations shall not constitute a default or an Event of Default with respect
to such Debt Securities ("covenant defeasance") (Section 1403), in either case
upon the irrevocable deposit by PTR with the Trustee, in trust, of an amount,
in such currency or currencies, currency unit or units or composite currency
or currencies in which such Debt Securities are payable at Stated Maturity, or
Government Obligations (as defined below), or both, applicable to such Debt
Securities which through the scheduled payment of principal and interest in
accordance with their terms will provide money in an amount sufficient to pay
the principal of (and premium or Make-Whole Amount, if any) and interest on
such Debt Securities, and any mandatory sinking fund or analogous payments
thereon, on the scheduled due dates therefor.
 
  Such a trust may only be established if, among other things, PTR has
delivered to the Trustee an Opinion of Counsel (as specified in the Indenture)
to the effect that the Holders of such Debt Securities will not recognize
income, gain or loss for United States federal income tax purposes as a result
of such defeasance or covenant defeasance and will be subject to United States
federal income tax on the same amounts, in the same manner and at the same
times as would have been the case if such defeasance or covenant defeasance
had not occurred, and such Opinion of Counsel, in the case of defeasance, must
refer to and be based upon a ruling of the Internal Revenue Service or a
change in applicable United States federal income tax law occurring after the
date of the Indenture (Section 1404).
 
  "Government Obligations" means securities which are (i) direct obligations
of the United States of America or the government which issued the Foreign
Currency in which the Debt Securities of a particular series are payable, for
the payment of which its full faith and credit is pledged or (ii) obligations
of a Person controlled or supervised by and acting as an agency or
instrumentality of the United States of America or such government
 
                                      13
<PAGE>
 
which issued the Foreign Currency in which the Debt Securities of such series
are payable, the payment of which is unconditionally guaranteed as a full
faith and credit obligation by the United States of America or such other
government, which, in either case, are not callable or redeemable at the
option of the issuer thereof, and shall also include a depository receipt
issued by a bank or trust company as custodian with respect to any such
Government Obligation or a specific payment of interest on or principal of any
such Government Obligation held by such custodian for the account of the
holder of a depository receipt, provided that (except as required by law) such
custodian is not authorized to make any deduction from the amount payable to
the holder of such depository receipt from any amount received by the
custodian in respect of the Government Obligation or the specific payment of
interest on or principal of the Government Obligation evidenced by such
depository receipt (Section 101).
 
  Unless otherwise provided in the applicable Prospectus Supplement, if after
PTR has deposited funds and/or Government Obligations to effect defeasance or
covenant defeasance with respect to Debt Securities of any series, (i) the
Holder of a Debt Security of such series is entitled to, and does, elect
pursuant to Section 301 of the Indenture or the terms of such Debt Security to
receive payment in a currency, currency unit or composite currency other than
that in which such deposit has been made in respect of such Debt Security or
(ii) a Conversion Event (as defined below) occurs in respect of the currency,
currency unit or composite currency in which such deposit has been made, the
indebtedness represented by such Debt Security shall be deemed to have been,
and will be, fully discharged and satisfied through the payment of the
principal of (and premium or Make-Whole Amount, if any) and interest on such
Debt Security as they become due out of the proceeds yielded by converting the
amount so deposited in respect of such Debt Security into the currency,
currency unit or composite currency in which such Debt Security becomes
payable as a result of such election or such cessation of usage based on the
applicable market exchange rate (Section 1405). "Conversion Event" means the
cessation of use of (i) a currency, currency unit or composite currency (other
than the ECU or other currency unit) both by the government of the country
which issued such currency and for the settlement of transactions by a central
bank or other public institutions of or within the international banking
community, (ii) the ECU both within the European Monetary System and for the
settlement of transactions by public institutions of or within the European
Communities or (iii) any currency unit or composite currency other than the
ECU for the purposes for which it was established. Unless otherwise provided
in the applicable Prospectus Supplement, all payments of principal of (and
premium or Make-Whole Amount, if any) and interest on any Debt Security that
is payable in a Foreign Currency that ceases to be used by its government of
issuance shall be made in United States dollars (Section 101).
 
  In the event PTR effects covenant defeasance with respect to any Debt
Securities and such Debt Securities are declared due and payable because of
the occurrence of any Event of Default other than the Event of Default
described in clause (iv) under "--Events of Default, Notice and Waiver" with
respect to Sections 1004 to 1009, inclusive, of the Indenture (which Sections
would no longer be applicable to such Debt Securities) or described in clause
(vii) under "--Events of Default, Notice and Waiver" with respect to any other
covenant as to which there has been covenant defeasance, the amount in such
currency, currency unit or composite currency in which such Debt Securities
are payable, and Government Obligations on deposit with the Trustee, will be
sufficient to pay amounts due on such Debt Securities at the time of their
Stated Maturity but may not be sufficient to pay amounts due on such Debt
Securities at the time of the acceleration resulting from such Event of
Default. However, PTR would remain liable to make payment of such amounts due
at the time of acceleration.
 
  The applicable Prospectus Supplement may further describe the provisions, if
any, permitting such defeasance or covenant defeasance, including any
modifications to the provisions described above, with respect to the Debt
Securities of or within a particular series.
 
REGISTRATION AND TRANSFER
 
  Subject to certain limitations imposed upon Debt Securities issued in book-
entry form, the Debt Securities of any series will be exchangeable for other
Debt Securities of the same series and of a like aggregate principal amount
and tenor of different authorized denominations upon surrender of such Debt
Securities at the corporate
 
                                      14
<PAGE>
 
trust office of the Trustee referred to above. In addition, subject to certain
limitations imposed upon Debt Securities issued in book-entry form, the Debt
Securities of any series may be surrendered for conversion or registration of
transfer thereof at the corporate trust office of the Trustee referred to
above. Every Debt Security surrendered for registration of transfer or
exchange shall be duly endorsed or accompanied by a written instrument of
transfer. No service charge will be made for any registration of transfer or
exchange of any Debt Securities, but PTR may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith (Section 305). PTR may at any time designate a transfer agent (in
addition to the Trustee) with respect to any series of Debt Securities. If PTR
has designated such a transfer agent or transfer agents, PTR may at any time
rescind the designation of any such transfer agent or approve a change in the
location at which any such transfer agent acts, except that PTR will be
required to maintain a transfer agent in each Place of Payment for such series
(Section 1002).
 
  Neither PTR nor the Trustee shall be required to (i) issue, register the
transfer of or exchange Debt Securities of any series during a period
beginning at the opening of business 15 days before any selection of Debt
Securities of that series to be redeemed and ending at the close of business
on the day of mailing of the relevant notice of redemption; (ii) register the
transfer of or exchange any Debt Security, or portion thereof, called for
redemption, except the unredeemed portion of any Debt Security being redeemed
in part; or (iii) issue, register the transfer of or exchange any Debt
Security which has been surrendered for repayment at the option of the Holder,
except the portion, if any, of such Debt Security not to be so repaid (Section
305).
 
BOOK-ENTRY PROCEDURES
 
  The Debt Securities of a series may be issued in whole or in part in the
form of one or more global securities ("Global Securities") that will be
deposited with, or on behalf of, a depository (the "Depository") identified in
the applicable Prospectus Supplement relating to such series. Global
Securities, if any, are expected to be deposited with The Depository Trust
Company, as Depository. Global Securities may be issued in fully registered
form and may be issued in either temporary or permanent form. Unless and until
it is exchanged in whole or in part for the individual Debt Securities
represented thereby, a Global Security may not be transferred except as a
whole by the Depository for such Global Security to a nominee of such
Depository or by a nominee of such Depository to such Depository or another
nominee of such Depository or by the Depository or any nominee of such
Depository to a successor Depository or any nominee of such successor.
 
  The specific terms of the depository arrangement with respect to a series of
Debt Securities will be described in the applicable Prospectus Supplement
relating to such series. Unless otherwise indicated in the applicable
Prospectus Supplement, PTR anticipates that the following provisions will
apply to depository arrangements.
 
  Upon the issuance of a Global Security, the Depository for such Global
Security or its nominee will credit on its book-entry registration and
transfer system the respective principal amounts of the individual Debt
Securities represented by such Global Security to the accounts of persons that
have accounts with such Depository ("Participants"). Such accounts shall be
designated by the underwriters, dealers or agents with respect to such Debt
Securities or by PTR if such Debt Securities are offered and sold directly by
PTR. Ownership of beneficial interests in a Global Security will be limited to
Participants or persons that may hold interests through Participants.
Ownership of beneficial interests in such Global Security will be shown on,
and the transfer of that ownership will be effected only through, records
maintained by the applicable Depository or its nominee (with respect to
beneficial interests of Participants) and records of Participants (with
respect to beneficial interests of persons who hold through Participants). The
laws of some states require that certain purchasers of securities take
physical delivery of such securities in definitive form. Such limits and laws
may impair the ability to own, pledge or transfer beneficial interest in a
Global Security.
 
  So long as the Depository for a Global Security or its nominee is the
registered owner of such Global Security, such Depository or such nominee, as
the case may be, will be considered the sole owner or holder of the Debt
Securities represented by such Global Security for all purposes under the
Indenture. Except as provided
 
                                      15
<PAGE>
 
below or in the applicable Prospectus Supplement, owners of beneficial
interest in a Global Security will not be entitled to have any of the
individual Debt Securities of the series represented by such Global Security
registered in their names, will not receive or be entitled to receive physical
delivery of any such Debt Securities of such series in definitive form and
will not be considered the owners or holders thereof under the Indenture.
 
  Payments of principal of, any premium or Make-Whole Amount and any interest
on, or any Additional Amounts payable with respect to, individual Debt
Securities represented by a Global Security registered in the name of a
Depository or its nominee will be made to the Depository or its nominee, as
the case may be, as the registered owner of the Global Security representing
such Debt Securities. None of PTR, the Trustee, any Paying Agent or the
Security Registrar for such Debt Securities will have any responsibility or
liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests in the Global Security for such Debt
Securities or for maintaining, supervising or reviewing any records relating
to such beneficial ownership interests.
 
  PTR expects that the Depository for a series of Debt Securities or its
nominee, upon receipt of any payment of principal, premium, Make-Whole Amount
or interest in respect of a permanent Global Security representing any of such
Debt Securities, immediately will credit Participants' accounts with payments
in amounts proportionate to their respective beneficial interests in the
principal amount of such Global Security for such Debt Securities as shown on
the records of such Depository or its nominee. PTR also expects that payments
by Participants to owners of beneficial interests in such Global Security held
through such Participants will be governed by standing instructions and
customary practices, as is the case with securities held for the account of
customers in bearer form or registered in "street name." Such payments will be
the responsibility of such Participants.
 
  If a Depository for a series of Debt Securities is at any time unwilling,
unable or ineligible to continue as depository and a successor depository is
not appointed by PTR within 90 days, PTR will issue individual Debt Securities
of such series in exchange for the Global Security representing such series of
Debt Securities. In addition, PTR may, at any time and in its sole discretion,
subject to any limitations described in the applicable Prospectus Supplement
relating to such Debt Securities, determine not to have any Debt Securities of
such series represented by one or more Global Securities and, in such event,
will issue individual Debt Securities of such series in exchange for the
Global Security or Securities representing such series of Debt Securities.
Individual Debt Securities of such series so issued will be issued in
denominations, unless otherwise specified by PTR, of $1,000 and integral
multiples thereof.
 
NO PERSONAL LIABILITY
 
  No past, present or future trustee, officer, employee or shareholder, as
such, of PTR or any successor thereof shall have any liability for any
obligations of PTR under the Debt Securities or the Indenture or for any claim
based on, in respect of, or by reason of, such obligations or their creation.
Each Holder of Debt Securities by accepting such Debt Securities waives and
releases all such liability. The waiver and release are part of the
consideration for the issue of Debt Securities (Section 111).
 
TRUSTEE
 
  The Indenture provides that there may be more than one Trustee thereunder,
each with respect to one or more series of Debt Securities. Any Trustee under
the Indenture may resign or be removed with respect to one or more series of
Debt Securities, and a successor Trustee may be appointed to act with respect
to such series (Section 608). In the event that two or more persons are acting
as Trustee with respect to different series of Debt Securities, each such
Trustee shall be a Trustee of a trust under the Indenture separate and apart
from the trust administered by any other Trustee (Sections 101 and 609), and
except as otherwise indicated herein, any action described herein to be taken
by the Trustee may be taken by each such Trustee with respect to, and only
with respect to, the one or more series of Debt Securities for which it is
Trustee under the Indenture.

                        DESCRIPTION OF PREFERRED SHARES
 
GENERAL
 
  Subject to limitations prescribed by Maryland law and the Declaration of
Trust, the Board is authorized to issue, from the authorized but unissued
shares of beneficial interest of PTR, Preferred Shares in series and to
establish from time to time the number of Preferred Shares to be included in
such series and to fix the designation and any preferences, conversion and
other rights, voting powers, restrictions, limitations as to dividends,
qualifications and terms and conditions of redemption of the shares of each
series, and such other subjects or matters as may be fixed by resolution of
the Board or a duly authorized committee thereof. On September 5, 1997, PTR
had 5,534,199 of its Series A Preferred Shares issued and outstanding and held
of record by approximately 75 shareholders and 4,200,000 of its Series B
Preferred Shares issued and outstanding and held of record by approximately
283 shareholders.
 
  Reference is made to the Prospectus Supplement relating to the series of
Preferred Shares being offered for the specific terms thereof, including:
 
    (1) The title and stated value of such series of Preferred Shares;
 
    (2) The number of shares of such series of Preferred Shares offered, the
  liquidation preference per share and the offering price of such Preferred
  Shares;
 
    (3) The dividend rate(s), period(s) and/or payment date(s) or method(s)
  of calculation thereof applicable to Preferred Shares of such series;
 
    (4) The date from which dividends on Preferred Shares of such series
  shall cumulate, if applicable;
 
    (5) The procedures for any auction and remarketing, if any, for Preferred
  Shares of such series;
 
    (6) The provision for a sinking fund, if any, for Preferred Shares of
  such series;
 
    (7) The provision for redemption, if applicable, of Preferred Shares of
  such series;
 
    (8) Any listing of such series of Preferred Shares on any securities
  exchange;
 
    (9) The terms and conditions, if applicable, upon which Preferred Shares
  of such series will be convertible into Common Shares, including the
  conversion price (or manner of calculation thereof);
 
    (10) Whether interests in Preferred Shares of such series will be
  represented by Global Securities;
 
    (11) Any other specific terms, preferences, rights, limitations or
  restrictions of such series of Preferred Shares;
 
    (12) A discussion of federal income tax considerations applicable to
  Preferred Shares of such series;
 
    (13) The relative ranking and preferences of Preferred Shares of such
  series as to dividend rights and rights upon liquidation, dissolution or
  winding up of the affairs of PTR;
 
    (14) Any limitations on issuance of any series of Preferred Shares
  ranking senior to or on a parity with such series of Preferred Shares as to
  dividend rights and rights upon liquidation, dissolution or winding up of
  the affairs of PTR; and
 
    (15) Any limitations on direct or beneficial ownership and restrictions
  on transfer of Preferred Shares of such series, in each case as may be
  appropriate to preserve the status of PTR as a REIT.
 
RANK
 
  Unless otherwise specified in the applicable Prospectus Supplement, the
Preferred Shares of each Series will, with respect to dividend rights and
rights upon liquidation, dissolution or winding up of PTR, rank (i) senior to
all classes or series of Common Shares, and to all equity securities ranking
junior to such series of Preferred Shares; (ii) on a parity with all equity
securities issued by PTR the terms of which specifically provide that such
equity securities rank on a parity with the Preferred Shares of such series;
and (iii) junior to all equity securities issued by PTR the terms of which
specifically provide that such equity securities rank senior to Preferred
Shares of such series.
 
                                      17
<PAGE>
 
DIVIDENDS
 
  Holders of Preferred Shares of each series shall be entitled to receive,
when, as and if declared by the Board, out of assets of PTR legally available
for payment, cash dividends at such rates and on such dates as will be set
forth in the applicable Prospectus Supplement. Each such dividend shall be
payable to holders of record as they appear on the share transfer books of PTR
on such record dates as shall be fixed by the Board.
 
  Dividends on any series of the Preferred Shares may be cumulative or
noncumulative, as provided in the applicable Prospectus Supplement. Dividends,
if cumulative, will be cumulative from and after the date set forth in the
applicable Prospectus Supplement. If the Board fails to declare a dividend
payable on a dividend payment date on any series of the Preferred Shares for
which dividends are noncumulative, then the holders of such series of the
Preferred Shares will have no right to receive a dividend in respect of the
dividend period ending on such dividend payment date, and PTR will have no
obligation to pay the dividend accrued for such period, whether or not
dividends on such series are declared payable on any future dividend payment
date.
 
  If Preferred Shares of any series are outstanding, no full dividends shall
be declared or paid or set apart for payment on the Preferred Shares of PTR of
any other series ranking, as to dividends, on a parity with or junior to the
Preferred Shares of such series for any period unless (i) if such series of
Preferred Shares has a cumulative dividend, full cumulative dividends have
been or contemporaneously are declared and paid or declared and a sum
sufficient for the payment thereof set apart for such payment on the Preferred
Shares of such series for all past dividend periods and the then current
dividend period or (ii) if such series of Preferred Shares does not have a
cumulative dividend, full dividends for the then current dividend period have
been or contemporaneously are declared and paid or declared and a sum
sufficient for the payment thereof set apart for such payment on the Preferred
Shares of such series. When dividends are not paid in full (or a sum
sufficient for such full payment is not so set apart) upon the Preferred
Shares of any series and the shares of any other series of Preferred Shares
ranking on a parity as to dividends with the Preferred Shares of such series,
all dividends declared upon Preferred Shares of such series and any other
series of Preferred Shares ranking on a parity as to dividends with such
Preferred Shares shall be declared pro rata so that the amount of dividends
declared per share on the Preferred Shares of such series and such other
series of Preferred Shares shall in all cases bear to each other the same
ratio that accrued dividends per share on the Preferred Shares of such series
(which shall not include any cumulation in respect of unpaid dividends for
prior dividend periods if such series of Preferred Shares does not have a
cumulative dividend) and such other series of Preferred Shares bear to each
other. No interest, or sum of money in lieu of interest, shall be payable in
respect of any dividend payment or payments on Preferred Shares of such series
which may be in arrears.
 
  Except as provided in the immediately preceding paragraph, unless (i) if
such series of Preferred Shares has a cumulative dividend, full cumulative
dividends on the Preferred Shares of such series have been or
contemporaneously are declared and paid or declared and a sum sufficient of
the payment thereof set apart for payment for all past dividend periods and
the then current dividend period or (ii) if such series of Preferred Shares
does not have a cumulative dividend, full dividends on the Preferred Shares of
such series have been or contemporaneously are declared and paid or declared
and a sum sufficient for the payment thereof set apart for payment for the
then current dividend period, no dividends (other than in Common Shares or
other capital shares ranking junior to the Preferred Shares of such series as
to dividends and upon liquidation) shall be declared or paid or set aside for
payment or other distribution shall be declared or made upon the Common Shares
or any other capital shares of PTR ranking junior to or on a parity with the
Preferred Shares of such series as to dividends or upon liquidation, nor shall
any Common Shares or any other capital shares of PTR ranking junior to or on a
parity with the Preferred Shares of such series as to dividends or upon
liquidation be redeemed, purchased or otherwise acquired for any consideration
(or any moneys be paid to or made available for a sinking fund for the
redemption of any shares of any such series) by PTR (except by conversion into
or exchange for other capital shares of PTR ranking junior to the Preferred
Shares of such series as to dividends and upon liquidation).
 
  Any dividend payment made on a series of Preferred Shares shall first be
credited against the earliest accrued but unpaid dividend due with respect to
shares of such series which remains payable.
 
                                      18

REDEMPTION
 
  If so provided in the applicable Prospectus Supplement, the Preferred Shares
will be subject to mandatory redemption or redemption at the option of PTR, as
a whole or in part, in each case upon the terms, at the times and at the
redemption prices set forth in such Prospectus Supplement.
 
  The Prospectus Supplement relating to a series of Preferred Shares that is
subject to mandatory redemption will specify the number of Preferred Shares of
such series that shall be redeemed by PTR in each year commencing after a date
to be specified, at a redemption price per share to be specified, together
with an amount equal to all accrued and unpaid dividends thereon (which shall
not, if such series of Preferred Shares does not have a cumulative dividend,
include any cumulation in respect of unpaid dividends for prior dividend
periods) to the date of redemption. The redemption price may be payable in
cash or other property, as specified in the applicable Prospectus Supplement.
If the redemption price for Preferred Shares of any series is payable only
from the net proceeds of the issuance of capital shares of PTR, the terms of
such series of Preferred Shares may provide that, if no such capital shares
shall have been issued or to the extent the net proceeds from any issuance are
insufficient to pay in full the aggregate redemption price then due, Preferred
Shares of such series shall automatically and mandatorily be converted into
shares of the applicable capital shares of PTR pursuant to conversion
provisions specified in the applicable Prospectus Supplement.
 
  Notwithstanding the foregoing, unless (i) if such series of Preferred Shares
has a cumulative dividend, full cumulative dividends on all Preferred Shares
of any series shall have been or contemporaneously are declared and paid or
declared and a sum sufficient for the payment thereof set apart for payment
for all past dividend periods and the then current dividend period or (ii) if
such series of Preferred Shares does not have a cumulative dividend, full
dividends on all Preferred Shares of any series have been or contemporaneously
are declared and paid or declared and a sum sufficient for the payment thereof
set apart for payment for the then current dividend period, no Preferred
Shares of any series shall be redeemed unless all outstanding Preferred Shares
of such series are simultaneously redeemed; provided, however, that the
foregoing shall not prevent the purchase or acquisition of Preferred Shares of
such series pursuant to a purchase or exchange offer made on the same terms to
holders of all outstanding Preferred Shares of such series, and, unless (i) if
such series of Preferred Shares has a cumulative dividend, full cumulative
dividends on all Preferred Shares of any series have been or contemporaneously
are declared and paid or declared and a sum sufficient for the payment thereof
set apart for payment for all past dividend periods and the then current
dividend period or (ii) if such series of Preferred Shares does not have a
cumulative dividend, full dividends on all Preferred Shares of any series have
been or contemporaneously are declared and paid or declared and a sum
sufficient for the payment thereof set apart for payment for the then current
dividend period, PTR shall not purchase or otherwise acquire directly or
indirectly any Preferred Shares of such series (except by conversion into or
exchange for capital shares of PTR ranking junior to the Preferred Shares of
such series as to dividends and upon liquidation).
 
  If fewer than all of the outstanding Preferred Shares of any series are to
be redeemed, the number of shares to be redeemed will be determined by PTR and
such shares may be redeemed pro rata from the holders of record of Preferred
Shares of such series in proportion to the number of Preferred Shares of such
series held by such holders (with adjustments to avoid redemption of
fractional shares) or by lot in a manner determined by PTR.
 
  Notice of redemption will be mailed at least 30 days but not more than 90
days before the redemption date to each holder of record of Preferred Shares
of any series to be redeemed at the address shown on the share transfer books
of PTR. Each notice shall state: (i) the redemption date; (ii) the number of
shares and series of the Preferred Shares to be redeemed; (iii) the redemption
price; (iv) the place or places where certificates for such Preferred Shares
are to be surrendered for payment of the redemption price; (v) that dividends
on the Preferred Shares to be redeemed will cease to accrue on such redemption
date; and (vi) the date upon which the holder's conversion rights, if any, as
to such Preferred Shares shall terminate. If fewer than all the Preferred
Shares of any series are to be redeemed, the notice mailed to each such holder
thereof shall also specify the number of Preferred Shares to be redeemed from
each such holder. If notice of redemption of any Preferred Shares has been
given and if the funds necessary for such redemption have been set aside by
PTR in trust for the benefit of
 
                                      19
<PAGE>
 
the holders of any Preferred Shares so called for redemption, then from and
after the redemption date dividends will cease to accrue on such Preferred
Shares, and all rights of the holders of such Preferred Shares will terminate,
except the right to receive the redemption price.
 
LIQUIDATION PREFERENCE
 
  Upon any voluntary or involuntary liquidation, dissolution or winding up of
the affairs of PTR, then, before any distribution or payment shall be made to
the holders of any Common Shares or any other class or series of shares of
beneficial interest of PTR ranking junior to such series of Preferred Shares
in the distribution of assets upon any liquidation, dissolution or winding up
of PTR, the holders of each series of Preferred Shares shall be entitled to
receive out of assets of PTR legally available for distribution to
shareholders liquidating distributions in the amount of the liquidation
preference per share (set forth in the applicable Prospectus Supplement), plus
an amount equal to all dividends accrued and unpaid thereon (which shall not
include any cumulation in respect of unpaid dividends for prior dividend
periods if such series of Preferred Shares does not have a cumulative
dividend). After payment of the full amount of the liquidating distributions
to which they are entitled, the holders of Preferred Shares of such series
will have no right or claim to any of the remaining assets of PTR. In the
event that, upon any such voluntary or involuntary liquidation, dissolution or
winding up, the available assets of PTR are insufficient to pay the amount of
the liquidating distributions on all outstanding Preferred Shares of such
series and the corresponding amounts payable on all shares of other classes or
series of capital shares of PTR ranking on a parity with Preferred Shares of
such series in the distribution of assets, then the holders of Preferred
Shares of such series and all other such classes or series of capital shares
shall share ratably in any such distribution of assets in proportion to the
full liquidating distributions to which they would otherwise be respectively
entitled.
 
  If liquidating distributions shall have been made in full to all holders of
Preferred Shares of such series, the remaining assets of PTR shall be
distributed among the holders of any other classes or series of capital shares
ranking junior to the Preferred Shares of such series upon liquidation,
dissolution or winding up, according to their respective rights and
preferences and in each case according to their respective number of shares.
For such purposes, the consolidation or merger of PTR with or into any other
entity, or the sale, lease or conveyance of all or substantially all of the
property or business of PTR, shall not be deemed to constitute a liquidation,
dissolution or winding up of PTR.
 
VOTING RIGHTS
 
  Holders of the Preferred Shares of each series will not have any voting
rights, except as set forth below or in the applicable Prospectus Supplement
or as otherwise required by applicable law. The following is a summary of the
voting rights that, unless provided otherwise in the applicable Prospectus
Supplement, will apply to each series of Preferred Shares.
 
  If six quarterly dividends (whether or not consecutive) payable on the
Preferred Shares of such series or any other series of Preferred Shares
ranking on a parity with such series of Preferred Shares with respect in each
case to the payment of dividends, amounts upon liquidation, dissolution and
winding up ("Parity Shares") are in arrears, whether or not earned or
declared, the number of Trustees then constituting the Board will be increased
by two, and the holders of Preferred Shares of such series, voting together as
a class with the holders of any other series of Parity Shares (any such other
series, the "Voting Preferred Shares"), will have the right to elect two
additional trustees to serve on the Board at any annual meeting of
shareholders or a properly called special meeting of the holders of Preferred
Shares of such series and such Voting Preferred Shares and at each subsequent
annual meeting of shareholders until all such dividends and dividends for the
current quarterly period on the Preferred Shares of such series and such other
Voting Preferred Shares have been paid or declared and set aside for payment.
Such voting rights will terminate when all such accrued and unpaid dividends
have been declared and paid or set aside for payment. The term of office of
all trustees so elected will terminate with the termination of such voting
rights. For so long as Security Capital and certain of its affiliates
beneficially own in excess of 10% of the outstanding Common Shares, in any
such vote by holders of Preferred Shares of such series,
 
                                      20
<PAGE>
 
Security Capital and certain of its affiliates shall vote their Preferred
Shares of such series, if any, in the same respective percentages as the
Preferred Shares of such series and Voting Preferred Shares that are not held
by such persons.
 
  The approval of two-thirds of the outstanding Preferred Shares of such
series and all other series of Voting Preferred Shares similarly affected,
voting as a single class, is required in order to (i) amend PTR's Declaration
of Trust to affect materially and adversely the rights, preferences or voting
power of the holders of the Preferred Shares of such series or the Voting
Preferred Shares; (ii) enter into a share exchange that affects the Preferred
Shares of such series, consolidate with or merge into another entity, or
permit another entity to consolidate with or merge into PTR, unless in each
such case each Preferred Share of such series remains outstanding without a
material and adverse change to its terms and rights or is converted into or
exchanged for preferred shares of the surviving entity having preferences,
conversion or other rights, voting powers, restrictions, limitations as to
dividends, qualifications and terms or conditions of redemption thereof
identical to that of a Preferred Share of such series (except for changes that
do not materially and adversely affect the holders of the Preferred Shares of
such series); or (iii) authorize, reclassify, create, or increase the
authorized amount of any class of shares having rights senior to the Preferred
Shares of such series with respect to the payment of dividends or amounts upon
liquidation, dissolution or winding up. However, PTR may create additional
classes of Parity Shares and other series of Preferred Shares ranking junior
to such series of Preferred Shares with respect in each case to the payment of
dividends, amounts upon liquidation, dissolution and winding up ("Junior
Shares"), increase the authorized number of Parity Shares and Junior Shares
and issue additional series of Parity Shares and Junior Shares without the
consent of any holder of Preferred Shares of such series.
 
  Except as provided above and as required by law, the holders of Preferred
Shares of each series will not be entitled to vote on any merger or
consolidation involving PTR or a sale of all or substantially all of the
assets of PTR.
 
CONVERSION RIGHTS
 
  The terms and conditions, if any, upon which Preferred Shares of any series
are convertible into Common Shares will be set forth in the applicable
Prospectus Supplement relating thereto. Such terms will include the number of
Common Shares into which the Preferred Shares of such series are convertible,
the conversion price (or manner of calculation thereof), the conversion
period, provisions as to whether conversion will be at the option of the
holders of the Preferred Shares of such series or PTR, the events requiring an
adjustment of the conversion price and provisions affecting conversion in the
event of the redemption of the Preferred Shares of such series.
 
RESTRICTIONS ON OWNERSHIP
 
  As discussed below under "Description of Common Shares--Restriction on Size
of Holdings," for PTR to qualify as a REIT under the Internal Revenue Code of
1986, as amended (the "Code"), not more than 50% in value of its outstanding
shares of beneficial interest may be owned by five or fewer individuals at any
time during the last half of a taxable year, and the capital stock must be
beneficially owned by 100 or more persons during at least 335 days of PTR's
taxable year of 12 months. Therefore, the Articles Supplementary for each
series of Preferred Shares will contain certain provisions restricting the
ownership and transfer of the Preferred Shares (the "Preferred Shares
Ownership Limit Provision"). Except as otherwise described in the applicable
Prospectus Supplement relating thereto, the provisions of each Articles
Supplementary relating to the Preferred Shares Ownership Limit will provide
(as in the case of the Series A Preferred Shares and the Series B Preferred
Shares) as summarized below.
 
  The Preferred Shares Ownership Limit Provision will provide that, subject to
certain exceptions contained in such Articles Supplementary, no person, or
persons acting as a group, may beneficially own more than 25% of any series of
Preferred Shares outstanding at any time, except as a result of PTR's
redemption of Preferred Shares. Shares acquired in excess of the Preferred
Shares Ownership Limit Provision must be redeemed by PTR
 
                                      21
<PAGE>
 
at a price equal to the average daily per share closing sale price during the
30-day period ending on the business day prior to the redemption date. Such
redemption is not applicable if a person's ownership exceeds the limitations
due solely to PTR's redemption of Preferred Shares; provided that thereafter
any additional Preferred Shares acquired by such person shall be Excess Shares
(as hereinafter defined). See "Description of Common Shares--Restriction on
Size of Holdings." From and after the date of notice of such redemption, the
holder of the Preferred Shares thus redeemed shall cease to be entitled to any
distribution (other than distributions declared prior to the date of notice of
redemption), voting rights and other benefits with respect to such shares
except the right to receive payment of the redemption price determined as
described above. The Preferred Shares Ownership Limit Provision may not be
waived with respect to certain affiliates of PTR.
 
  All certificates representing shares of Preferred Shares will bear a legend
referring to the restrictions described above.
 
                         DESCRIPTION OF COMMON SHARES
 
GENERAL
 
  The Declaration of Trust authorizes PTR to issue up to 150,000,000 Shares of
Beneficial Interest, par value $1.00 per share, consisting of Common Shares,
Preferred Shares and such other types or classes of shares of beneficial
interest as the Board may create and authorize from time to time. At September
5, 1997 approximately 79,429,200 Common Shares were issued and outstanding and
held of record by approximately 3,000 shareholders.
 
  The following description sets forth certain general terms and provisions of
the Common Shares to which any Prospectus Supplement may relate, including a
Prospectus Supplement which provides for Common Shares issuable pursuant to
subscription offerings or rights offerings or upon conversion of Preferred
Shares which are offered pursuant to such Prospectus Supplement and
convertible into Common Shares for no additional consideration. The statements
below describing the Common Shares are in all respects subject to and
qualified in their entirety by reference to the applicable provisions of the
Declaration of Trust and PTR's Bylaws.
 
  The outstanding Common Shares are fully paid and, except as set forth below
under "--Shareholder Liability," non-assessable. Each Common Share entitles
the holder to one vote on all matters requiring a vote of shareholders,
including the election of Trustees. Holders of Common Shares do not have the
right to cumulate their votes in the election of Trustees, which means that
the holders of a majority of the outstanding Common Shares can elect all of
the Trustees then standing for election. Holders of Common Shares are entitled
to such distributions as may be declared from time to time by the Board out of
funds legally available therefor. Holders of Common Shares have no conversion,
redemption, preemptive or exchange rights to subscribe to any securities of
PTR. In the event of a liquidation, dissolution or winding up of the affairs
of PTR, the holders of the Common Shares are entitled to share ratably in the
assets of PTR remaining after provision for payment of all liabilities to
creditors and payment of liquidation preferences and accrued dividends, if
any, on the Series A Preferred Shares and Series B Preferred Shares, and
subject to the rights of holders of other series of Preferred Shares, if any.
The right of holders of the Common Shares are subject to the rights and
preferences established by the Board for the Series A Preferred Shares and
Series B Preferred Shares and any other series of Preferred Shares which may
subsequently be issued by PTR. See "Description of Preferred Shares."
 
PURCHASE RIGHTS
 
  On July 11, 1994, the Board declared a dividend of one preferred share
purchase right (a "Purchase Right") for each Common Share outstanding, payable
to holders of Common Shares of record at the close of business on July 21,
1994. The holders of any additional Common Shares issued after such date and
before the redemption or expiration of the Purchase Rights are also entitled
to receive one Purchase Right for each such additional Common Share. Each
Purchase Right entitles the holder under certain circumstances to purchase
from PTR one
 
                                      22
<PAGE>
 
one-hundredth of a share of a series of participating preferred shares, par
value $1.00 per share (the "Participating Preferred Shares") at a price of
$60.00 per one one-hundredth of a Participating Preferred Share, subject to
adjustment. Purchase Rights are exercisable when a person or group of persons
acquires 20% or more of the outstanding Common Shares (49% in the case of
Security Capital and its affiliates) or announces a tender offer or exchange
offer for 25% or more of the outstanding Common Shares. Under certain
circumstances, each Purchase Right entitles the holder to purchase, at the
Purchase Right's then current exercise price, a number of Common Shares having
a market value of twice the Purchase Right's exercise price. The acquisition
of PTR pursuant to certain mergers or other business transactions would
entitle each holder to purchase, at the Purchase Right's then current exercise
price, a number of the acquiring company's common shares having a market value
at the time equal to twice the Purchase Right's exercise price. The Purchase
Rights held by certain 20% shareholders (other than Security Capital) would
not be exercisable. The Purchase Rights will expire on July 21, 2004 and are
subject to redemption in whole, but not in part, at a price of $.01 per
Purchase Right payable in cash, shares of PTR or any other form of
consideration determined by the Board.
 
TRANSFER AGENT
 
  The transfer agent and registrar for the Common Shares is ChaseMellon
Shareholder Services, L.L.C. The Common Shares are listed on the New York
Stock Exchange (the "NYSE") under the symbol "PTR."
 
RESTRICTION ON SIZE OF HOLDINGS
 
  The Declaration of Trust restricts beneficial ownership of PTR's outstanding
shares of beneficial interest by a single person, or persons acting as a
group, to 9.8% of such shares. The purposes of the restriction are to assist
in protecting and preserving PTR's REIT status and to protect the interest of
shareholders in takeover transactions by preventing the acquisition of a
substantial block of shares unless the acquiror makes a cash tender offer for
all outstanding shares. For PTR to qualify as a REIT under the Code, not more
than 50% in value of its outstanding shares of beneficial interest may be
owned by five or fewer individuals at any time during the last half of any
taxable year. The restriction permits five persons to acquire up to a maximum
of 9.8% each, or an aggregate of 49% of the outstanding shares, and, thus,
assist the Board in protecting and preserving PTR's REIT status for tax
purposes. This restriction does not apply to Security Capital, which counts as
numerous holders for purposes of the tax rule, because its shares are
attributed to its shareholders for purposes of this rule.
 
  Shares of beneficial interest owned by a person or group of persons in
excess of 9.8% (49% in the case of Security Capital and its affiliates) of the
outstanding shares of beneficial interest ("Excess Shares") are subject to
redemption by PTR, at its option, upon 30 days' notice, at a price equal to
the average daily per share closing sale price during the 30-day period ending
on the business day prior to the redemption date. PTR may make payment of the
redemption price at any time or times up to the earlier of five years after
the redemption date or liquidation of PTR. PTR may refuse to effect the
transfer of any shares of beneficial interest which would make the transferee
a holder of Excess Shares. Shareholders of PTR are required to disclose, upon
demand of the Board, such information with respect to their direct and
indirect ownership of shares of PTR as the Board deems necessary to comply
with the provisions of the Code pertaining to qualification, for tax purposes,
of REITs, or to comply with the requirements of any other appropriate taxing
authority.
 
  The 9.8% restriction does not apply to acquisitions by any underwriter in a
public offering and sale of shares of beneficial interest of PTR or to any
transaction involving the issuance of shares of beneficial interest in which a
majority of the Board determines that the eligibility of PTR to qualify as a
REIT for federal income tax purposes will not be jeopardized or the
disqualification of PTR as a REIT is advantageous to the shareholders.
Security Capital's ownership of shares is attributed for tax purposes to its
shareholders. The Board has permitted Security Capital to acquire up to 49% of
the outstanding Common Shares.
 
TRUSTEE LIABILITY
 
  The Declaration of Trust provides that Trustees shall not be individually
liable for any obligation or liability incurred by or on behalf of PTR or by
Trustees for the benefit and on behalf of PTR. Under the Declaration of
 
                                      23
<PAGE>
 
Trust and Maryland law governing REITs, Trustees are not liable to PTR or the
shareholders for any act or omission except for acts or omissions which
constitute bad faith, willful misfeasance or gross negligence in the conduct
of their duties.
 
SHAREHOLDER LIABILITY
 
  Both Maryland statutory law governing REITs organized under the laws of the
state and the Declaration of Trust provide that shareholders shall not be
personally or individually liable for any debt, act, omission or obligation of
PTR or the Board. The Declaration of Trust further provides that PTR shall
indemnify and hold each shareholder harmless from all claims and liabilities
to which the shareholder may become subject by reason of his or her being or
having been a shareholder and that PTR shall reimburse each shareholder for
all legal and other expenses reasonably incurred by the shareholder in
connection with any such claim or liability, except to the extent that such
claim or liability arises out of the shareholder's bad faith, willful
misconduct or gross negligence and provided that such shareholder gives PTR
prompt notice of any such claim or liability and permits PTR to conduct the
defense thereof. In addition, PTR is required to, and as a matter of practice
does, insert a clause in its management and other contracts providing that
shareholders assume no personal liability for obligations entered into on
behalf of PTR. Nevertheless, with respect to tort claims, contractual claims
where shareholder liability is not so negated, claims for taxes and certain
statutory liability, the shareholders may, in some jurisdictions, be
personally liable to the extent that such claims are not satisfied by PTR.
Inasmuch as PTR carries public liability insurance which it considers
adequate, any risk of personal liability to shareholders is limited to
situations in which PTR's assets plus its insurance coverage would be
insufficient to satisfy the claims against PTR and its shareholders.
 
                       FEDERAL INCOME TAX CONSIDERATIONS
 
  PTR intends to operate in a manner that permits it to satisfy the
requirements for taxation as a REIT under the applicable provisions of the
Code. No assurance can be given, however, that such requirements will be met.
The following is a description of the federal income tax consequences to PTR
and its shareholders of the treatment of PTR as a REIT. Since these provisions
are highly technical and complex, each prospective purchaser of the Offered
Securities is urged to consult his or her own tax advisor with respect to the
federal, state, local, foreign and other tax consequences of the purchase,
ownership and disposition of the Offered Securities.
 
  Based upon certain representations of PTR with respect to the facts as set
forth and explained in the discussion below, in the opinion of Mayer, Brown &
Platt, counsel to PTR, PTR has been organized in conformity with the
requirements for qualification as a REIT, and its proposed method of operation
described in this Prospectus and as represented by management will enable it
to satisfy the requirements for such qualification.
 
  This opinion is conditioned upon certain representations made by PTR as to
certain factual matters relating to PTR's organization and intended or
expected manner of operation. In addition, this opinion is based on the law
existing and in effect on the date hereof. PTR's qualification and taxation as
a REIT will depend on PTR's ability to meet on a continuing basis, through
actual operating results, asset composition, distribution levels and diversity
of stock ownership, the various qualification tests imposed under the Code
discussed below. Mayer, Brown & Platt will not review compliance with these
tests on a continuing basis. No assurance can be given that PTR will satisfy
such tests on a continuing basis.
 
  In brief, if certain detailed conditions imposed by the REIT provisions of
the Code are met, entities such as PTR, that invest primarily in real estate
and that otherwise would be treated for federal income tax purposes as
corporations, are generally not taxed at the corporate level on their "REIT
taxable income" that is currently distributed to shareholders. This treatment
substantially eliminates the "double taxation" (at both the corporate and
shareholder levels) that generally results from the use of corporations.
 
  If PTR fails to qualify as a REIT in any year, however, it will be subject
to federal income taxation as if it were a domestic corporation, and its
shareholders will be taxed in the same manner as shareholders of ordinary
 
                                      24
<PAGE>
 
corporations. In this event, PTR could be subject to potentially significant
tax liabilities, and therefore the amount of cash available for distribution
to its shareholders would be reduced or eliminated.
 
  The Board believes that PTR has been organized and operated and currently
intends that PTR will continue to operate in a manner that permits it to
qualify as a REIT. There can be no assurance, however, that this expectation
will be fulfilled, since qualification as a REIT depends on PTR continuing to
satisfy numerous asset, income and distribution tests described below, which
in turn will be dependent in part on PTR's operating results.
 
  The following summary is based on existing law, is not exhaustive of all
possible tax considerations and does not give a detailed discussion of any
state, local, or foreign tax considerations, nor does it discuss all of the
aspects of federal income taxation that may be relevant to a prospective
shareholder in light of his or her particular circumstances or to certain
types of shareholders (including insurance companies, tax-exempt entities,
financial institutions or broker-dealers, foreign corporations and persons who
are not citizens or residents of the United States) subject to special
treatment under the federal income tax laws.
 
TAXATION OF PTR
 
  To qualify as a REIT under the Code for a taxable year, PTR must meet
certain organizational and operational requirements.
 
 Asset Tests
 
  At the close of each quarter of PTR's taxable year, PTR must satisfy certain
tests relating to the nature of its assets (determined in accordance with
generally accepted accounting principles). First, at least 75% of the value of
PTR's total assets must be represented by interests in real property,
interests in mortgages on real property, shares in other REITs, cash, cash
items, and government securities, and qualified temporary investments. Second,
although the remaining 25% of PTR's assets generally may be invested without
restriction, securities in this class may not exceed either (i) in the case of
securities of any non-government issuer, 5% of the value of PTR's total assets
or (ii) 10% of the outstanding voting securities of any one issuer.
 
 Gross Income Tests
 
  For each taxable year at least 75% of PTR's gross income must be derived
from certain real estate sources, including rents from real property and
interest on mortgage obligations. Real estate sources for purposes of those
requirements also include gains from the sale of real property not held
primarily for sale to customers in the ordinary course of business, dividends
on REIT shares, interest on loans secured by mortgages on real property and
income from foreclosure property. For rents to qualify, they may not be based
on the income or profits of any person, except that they may be based on a
percentage or percentages of gross income or receipts, and, subject to certain
limited exceptions, the REIT's management of the property and rendering of
services to tenants must either be with respect to usual or customary services
or furnished through a qualified independent contractor. For taxable years
beginning after August 5, 1997, the Taxpayer Relief Act of 1997 (the "1997
Act") permits a REIT to render a de minimis amount of impermissible services
to tenants, or in connection with the management of property, and still treat
amounts received with respect to that property as rent. The value of the
impermissible services may not exceed one percent of the gross income from the
property.
 
  In addition to deriving 75% of its gross income from the sources listed
above, at least 95% of PTR's gross income for the taxable year must be derived
from real estate sources described above or from dividends, interest, gains
from the sale or disposition of stock or other securities that are not dealer
property and specified other items. Dividends (including PTR's share of any
dividends paid by PTR Development Services Incorporated ("PTR Development
Services") and interest on any obligations not collateralized by an interest
in real property qualify for purposes of the 95% test, but not for purposes of
that 75% test.
 
  PTR must also derive less than 30% of its gross income for each taxable year
from the sale or other disposition of: (i) real property held for less than
four years (other than foreclosure property and by reason of
 
                                      25
<PAGE>
 
involuntary conversion); (ii) stock or securities held for less than one year;
and (iii) property in a prohibited transaction. The 30% gross income test has
been repealed by the 1997 Act for taxable years beginning after August 5,
1997.
 
 Ownership Restrictions
 
  PTR must satisfy certain ownership restrictions under the Code that limit
(i) concentration of ownership of its shares of capital stock by specified
persons and (ii) ownership by PTR of its tenants. The Declaration of Trust
restricts the transfer of shares when necessary to maintain PTR's
qualification as a REIT under these standards. See "Description of Common
Shares--Restrictions on Size of Holdings." However, because the Code imposes
broad attribution rules in determining constructive ownership, no assurance
can be given that these restrictions would be effective in maintaining PTR's
REIT status.
 
 Annual Distribution Requirements
 
  So long as PTR qualifies for taxation as a REIT and distributes at least 95%
of its real estate investment trust taxable income (computed without respect
to net capital gains or the dividends paid deduction) for each taxable year to
its shareholders annually, PTR itself will not be subject to federal income
tax on that portion of such income distributed to shareholders. PTR will be
taxed at regular corporate rates on all income not distributed to
shareholders. Nevertheless, it is PTR's policy to distribute at least 95% of
its taxable income. For taxable years beginning after August 5, 1997, the 1997
Act permits a REIT to elect to retain and pay income tax on net long-term
capital gains it received during the tax year. Thus, if PTR made this
election, the shareholders of PTR would include in their income as long-term
capital gains their proportionate share of the undistributed long-term capital
gains as designated by PTR. Each shareholder of PTR would be deemed to have
paid such shareholder's share of the tax, which would be credited or refunded
to the shareholder. REITs may also incur taxes for certain other activities.
 
 Failure to Quality
 
  If PTR fails to qualify for taxation as a REIT in any taxable year and
certain relief provisions do not apply, PTR will be subject to tax (including
applicable alternative minimum tax) on its taxable income at regular corporate
rates. Distributions to shareholders in any year in which PTR fails to quality
as a REIT will not be deductible by PTR, nor generally will they be required
to be made under the Code. In such event, to the extent of current and
accumulated earnings and profits, all distributions to shareholders will be
taxable as ordinary income, and subject to certain limitations in the Code,
corporate distributees may be eligible for the dividends-received deduction.
Unless entitled to relief under specific statutory provisions, PTR also will
be disqualified from reelecting taxation as a REIT for the four taxable years
following the year during which qualification was lost.
 
TAXATION OF PTR'S SHAREHOLDERS
 
  Distributions paid to PTR's shareholders out of current or accumulated
earnings and profits of PTR will generally be taxed to them as ordinary
income. Such distributions are not eligible for the dividends-receivable
deduction for corporations. PTR's earnings and profits will first be allocated
to any outstanding Preferred Shares. A distribution of net capital gains by
PTR will generally be treated as a long-term capital gain to shareholders to
the extent properly designated by PTR as a capital gain distribution and
regardless of the length of time a shareholder has held his shares. Capital
gains distributions are not eligible for the dividends-received deduction for
corporations. Any loss on a sale of shares that were held for six months or
less and with respect to which a capital gain distribution was received will
be treated as a long-term capital loss, up to the amount of the capital gain
distribution received with respect to such shares. A distribution in excess of
current or accumulated earnings and profits will constitute a nontaxable
return of capital, to the extent of the shareholder's basis in his shares. To
the extent such a distribution exceeds such basis, it will be treated as
capital gain to those shareholders holding their shares as capital assets. PTR
will notify each shareholder as to the portions of each distribution that, in
its view, constitute ordinary income, capital gain or return of capital.
Should PTR incur ordinary or capital losses, shareholders will not be entitled
to include such losses in their own income tax returns.

OTHER TAX CONSIDERATIONS
 
 Homestead Mortgages
 
  PTR holds mortgage notes of Homestead Village Incorporated ("Homestead")
which are convertible into shares of Homestead common stock. Pursuant to the
terms of the funding commitment agreement, PTR funds $900,000 for each
$1,000,000 of convertible mortgage loans. Pursuant to Sections 1271 through
1275 of the Code and regulations thereunder, PTR will be treated as having
acquired the convertible mortgage loans with original issue discount in an
amount equal to the difference between the issue price (the amount funded by
PTR) and the principal amount at maturity of the convertible mortgage loans.
PTR will be required to accrue such original issue discount in income on a
yield to maturity basis over the terms of the convertible mortgage loans
before receipt of the cash attributable to such income. Because PTR is
generally required to distribute 95% of its income in order to retain its REIT
status and 100% of its income to avoid being taxed, PTR may be required to
borrow funds in order to distribute amounts attributable to any such original
issue discount. Interest paid by Homestead (and the original issue discount)
to PTR on the mortgage notes constitutes qualified income for purposes of
determining whether PTR meets the gross income requirements for REIT
qualification.
 
  The terms of the mortgages provide for adjustment of the price for
conversion of the mortgages into the Homestead common stock if Homestead makes
certain distributions of stock, cash or other property to its shareholders. If
Homestead makes a distribution of cash or property resulting in an adjustment
to the conversion price, PTR, as a holder of such convertible mortgages, may
be viewed as receiving a "deemed distribution" under Section 305 of the Code,
even if PTR does not hold any Homestead common stock at such time. The deemed
distribution would constitute a taxable dividend, taxable as ordinary income,
to the extent that the earnings and profits of Homestead were allocable to the
deemed distribution. The amount of the deemed distribution which exceeded the
allocated earnings and profits of Homestead would be considered a return of
capital and would reduce PTR's tax basis in the convertible mortgages (but not
below zero) by the value of the deemed distribution. To the extent that the
value of the deemed distribution exceeds PTR's tax basis in the convertible
mortgages, the deemed distribution would result in gain to PTR. PTR's tax
basis in the convertible mortgages would then immediately be increased by the
value of the property deemed to have been distributed.
 
  Except as discussed below with respect to cash received in lieu of
fractional shares of Homestead common stock, PTR will not recognize gain or
loss upon the exercise of the conversion right. PTR's tax basis in the
Homestead common stock received upon the conversion will be equal to PTR's tax
basis in the mortgages converted. Upon conversion of the mortgages, PTR will
receive cash in lieu of any fractional shares of Homestead common stock and
will recognize gain to the extent that the cash received exceeds PTR's tax
basis in the portion of the mortgages converted for cash in lieu of fractional
shares. In the event that PTR exercises its conversion right, it is expected
that PTR, consistent with its status as a REIT, will shortly thereafter
distribute to its shareholders or sell in the open market the Homestead common
stock received. PTR will recognize gain upon such distribution or sale of the
Homestead common stock received upon conversion in an amount equal to the
excess of the fair market value of the Homestead common stock over PTR's tax
basis therein, and the earnings and profits of PTR will be increased by the
amount of any such gain recognized. In computing its taxable income for the
year in which any Homestead common stock is distributed, PTR will be allowed a
dividends-paid deduction in an amount equal to the fair market value at the
time of distribution of the Homestead common stock distributed, but in no
event in excess of the earnings and profits of PTR.
 
 PTR Development Services
 
  PTR Development Services will pay Federal and state income taxes at the full
applicable corporate rates on its income prior to payment of any dividends.
PTR Development Services will attempt to minimize the amount of such taxes,
but there can be no assurance whether or to the extent to which measures taken
to minimize taxes will be successful. To the extent that PTR Development
Services is required to pay Federal, state or local taxes, the cash available
for distribution by PTR Development Services to its shareholders will be
reduced accordingly.

 Backup Withholding
 
  PTR will report to its domestic shareholders and to the Internal Revenue
Service the amount of distributions paid during each calendar year, and the
amount of tax withheld, if any, with respect thereto. Under the backup
withholding rules, a shareholder may be subject to backup withholding at
applicable rates with respect to distributions paid unless such shareholder
(i) is a corporation or comes within certain other exempt categories and, when
required, demonstrates this fact or (ii) provides a taxpayer identification
number, certifies as to no loss of exemption from backup withholding, and
otherwise complies with applicable requirements of the backup withholding
rules. A shareholder that does not provide PTR with its correct taxpayer
identification number may also be subject to penalties imposed by the IRS. Any
amount paid as backup withholding will be credited against the shareholder's
income tax liability. In addition, PTR may be required to withhold a portion
of capital gain distributions made to any shareholders who fail to certify
their non-foreign status to PTR.
 
  EACH PROSPECTIVE PURCHASER IS ADVISED TO CONSULT WITH HIS OR HER OWN TAX
ADVISOR REGARDING THE SPECIFIC TAX CONSEQUENCES TO HIM OR HER OF THE PURCHASE,
OWNERSHIP, AND SALES OF COMMON SHARES, PREFERRED SHARES OR DEBT SECURITIES IN
AN ENTITY ELECTING TO BE TAXED AS A REAL ESTATE INVESTMENT TRUST, INCLUDING
THE FEDERAL, STATE, LOCAL, FOREIGN, AND OTHER TAX CONSEQUENCES OF SUCH
PURCHASE, OWNERSHIP, SALE AND ELECTION AND OF POTENTIAL CHANGES IN APPLICABLE
TAX LAWS.
 
                             PLAN OF DISTRIBUTION
 
  PTR may sell the Offered Securities to one or more underwriters or dealers
for public offering and sale by them or may sell the Offered Securities to
investors directly or through agents, which agents may be affiliated with PTR.
Direct sales to investors may be accomplished through subscription offerings
or through subscription rights distributed to PTR shareholders and direct
placements to third parties. In connection with subscription offerings or the
distribution of subscription rights to shareholders, if all the underlying
Offered Securities are not subscribed for, PTR may sell such unsubscribed
Offered Securities to third parties directly or through agents and, in
addition, whether or not all of the underlying Offered Securities are
subscribed for, PTR may concurrently offer additional Offered Securities to
third parties directly or through agents, which agents may be affiliated with
PTR. Any underwriter, dealer or agent involved in the offer and sale of the
Offered Securities will be named in the applicable Prospectus Supplement.
 
  The distribution of the Offered Securities may be effected from time to time
in one or more transactions at a fixed price or prices, which may be changed,
at prices related to the prevailing market prices at the time of sale or at
negotiated prices (any of which may represent a discount from the prevailing
market price). PTR also may, from time to time, authorize underwriters acting
as PTR's agents to offer and sell the Offered Securities upon the terms and
conditions set forth in the applicable Prospectus Supplement. In connection
with the sale of Offered Securities, underwriters may be deemed to have
received compensation from PTR in the form of underwriting discounts or
commissions and may also receive commissions from purchasers of Offered
Securities for whom they may act as agent. Underwriters may sell Offered
Securities to or through dealers, and such dealers may receive compensation in
the form of discounts, concessions or commissions from the underwriters and/or
commissions from the purchasers for whom they may act as agent.
 
  Any underwriting compensation paid by PTR to underwriters or agents in
connection with the offering of Offered Securities, and any discounts,
concessions or commissions allowed by underwriters to participating dealers,
will be set forth in the applicable Prospectus Supplement. Underwriters,
dealers and agents participating in the distribution of the Offered Securities
may be deemed to be underwriters, and any discounts and commissions received
by them and any profit realized by them on resale of the Offered Securities
may be deemed to be underwriting discounts and commissions, under the
Securities Act. Underwriters, dealers and agents may be entitled, under
agreements entered into with PTR, to indemnification against and contribution
toward certain
 
                                      28
<PAGE>
 
civil liabilities, including liabilities under the Securities Act. Any such
indemnification agreements will be described in the applicable Prospectus
Supplement.
 
  If so indicated in the applicable Prospectus Supplement, PTR will authorize
dealers acting as PTR's agents to solicit offers by certain institutions to
purchase Offered Securities from PTR at the public offering price set forth in
such Prospectus Supplement pursuant to Delayed Delivery Contracts
("Contracts") providing for payment and delivery on the date or dates stated
in such Prospectus Supplement. Each Contract will be for an amount not less
than, and the aggregate principal amount of Offered Securities sold pursuant
to Contracts shall be not less nor more than, the respective amounts stated in
the applicable Prospectus Supplement. Institutions with whom Contracts, when
authorized, may be made include commercial and savings banks, insurance
companies, pension funds, investment companies, educational and charitable
institutions, and other institutions but will in all cases be subject to the
approval of PTR. Contracts will not be subject to any conditions except (i)
the purchase by an institution of the Offered Securities covered by its
Contracts shall not at the time of delivery be prohibited under the laws of
any jurisdiction in the United States to which such institution is subject,
and (ii) if the Offered Securities are being sold to underwriters, PTR shall
have sold to such underwriters the total principal amount of the Offered
Securities less the principal amount thereof covered by Contracts.
 
  Certain of the underwriters and their affiliates may be customers of, engage
in transactions with and perform services for PTR and its subsidiaries in the
ordinary course of business.
 
                                    EXPERTS
 
  The financial statements of PTR as of December 31, 1996 and 1995, and for
each of the years in the three-year period ended December 31, 1996, and the
related schedule incorporated by reference herein, and the combined statements
of revenues and certain expenses for certain multifamily communities for the
years ended December 31, 1996 and 1995, incorporated by reference herein, have
been incorporated by reference herein and in the Registration Statement in
reliance upon the reports of KPMG Peat Marwick LLP, independent certified
public accountants, incorporated by reference herein and upon the authority of
said firm as experts in accounting and auditing.
 
  With respect to the unaudited condensed interim financial statements for the
periods ended March 31, 1997 and 1996 and June 30, 1997 and 1996, of PTR
incorporated by reference herein, the independent public accountants have
reported that they applied limited procedures in accordance with professional
standards for a review of such information. However, their separate report
included in PTR's quarterly report on Form 10-Q for the quarters ended March
31, 1997 and June 30, 1997, incorporated by reference herein, states that they
did not audit, and they do not express an opinion, on that interim financial
information. Accordingly, the degree of reliance on their report on such
information should be restricted considering the limited nature of the review
procedures applied. The accountants are not subject to the liability
provisions of Section 11 of the Securities Act for their report on the
unaudited interim financial information because such report is not a "report"
or a "part" of the Registration Statement prepared or certified by the
accountants within the meaning of Sections 7 and 11 of the Securities Act.
 
                                 LEGAL MATTERS
 
  The validity of the Offered Securities will be passed upon for PTR by Mayer,
Brown & Platt, Chicago, Illinois. Mayer, Brown & Platt has in the past
