PART I

Item 1. Business

Overview

     We are a self-administered and self-managed Maryland REIT that acquires,
owns, manages, leases, develops and builds primarily office properties
throughout the United States. We are self-administered in that we provide our
own administrative services, such as accounting, tax and legal, internally
through our own employees. We are self-managed in that we internally provide all
the management and maintenance services that our properties require through
employees, such as, property managers, leasing professionals and engineers. We
operate principally through our operating partnership, Prentiss Properties
Acquisition Partners, L.P., and its subsidiaries, and a management company,
Prentiss Properties Resources, Inc. and its subsidiaries. Our regional
management offices are located in San Diego, Oakland, Dallas, Chicago and
Washington, D.C. As of December 31, 2001, we owned interests in a diversified
portfolio of 146 primarily suburban Class A office and suburban industrial
properties as follows:

                                                Number of   Net Rentable
                                                Buildings    Square Feet
                                                ---------   ------------
                                                            (in millions)
Office Properties ...........................      108          14.4
Industrial Properties .......................       38           3.2
                                                   ---          ----

    Total ...................................      146          17.6
                                                   ===          ====

     The above properties consist of 108 office properties containing
approximately 14.4 million net rentable square feet and 38 industrial properties
containing approximately 3.2 million net rentable square feet. Our properties
include 3 office properties containing 445,000 net rentable square feet that are
in various stages of development. As of December 31, 2001, our properties,
exclusive of the development properties, were 94% leased to approximately 1,100
tenants. In addition to managing properties that we own, we manage approximately
19.7 million net rentable square feet in office, industrial and other properties
for third parties.

     Our primary business is the ownership and operation of office and
industrial properties throughout the United States. We have determined that our
reportable segments are those that are based on our method of internal
reporting, which disaggregates our business by geographic region. In April 2001,
we completed an asset exchange with Brandywine Realty Trust, which included the
sale of all of the properties comprising our Northeast Region, and as a result,
at December 31, 2001, we had no operations in the Northeast Region. In addition,
during December 2001, we changed our internal reporting dividing our West Region
into separate Northern and Southern California Regions. As of December 31, 2001,
our reportable segments include our five regions (1) Mid-Atlantic; (2) Midwest;
(3) Southwest; (4) Northern California; and (5) Southern California.

     Our properties are located in 12 markets, which are included in our
reportable segments as follows:

Reportable Segment       Market
------------------       ------

Mid-Atlantic             Metropolitan Washington, DC, Atlanta
Midwest                  Chicago, Suburban Detroit
Southwest                Austin, Dallas/Fort Worth, Denver, Houston
Northern California      Sacramento, San Francisco Bay Area
Southern California      Los Angeles, San Diego

     For revenues, profit and loss, and total asset information on each of our
segments, see Note (20) to our Consolidated Financial Statements.

Recent Developments

     Using proceeds from our revolving credit facility, in January 2002, we
contributed $3.0 million to a joint venture established to develop two
multi-story office buildings in Del Mar, California. Our contribution represents
a 70% controlling interest in the joint venture. Also using proceeds from our
revolving credit facility, we made a loan totaling $6.6 million to the joint
venture. The loan, which matures in January 2005, bears interest at 10% per
annum for the first twelve months of the loan term and 12% thereafter. The loan
requires interest only payments until maturity.

     Subsequent to year end, using proceeds from our revolving credit facility,
we purchased the Burnett Plaza Associates loan in the principal amount of $47.0
million from Teachers Insurance and Annuity Association of America. The loan
bears interest at 7.5% per annum through March 2002 and 10% per annum through
its maturity in December 2002. At the time we purchased this loan, we owned a
20% non-controlling partnership interest in Burnett Plaza Associates, the
borrower under the loan, which owns a 1.1 million net rentable square foot
office building in Fort Worth, Texas which secures the debt. In March 2002, we
purchased from Burnett Plaza - VEF III, L.P., an affiliate of Lend Lease Real
Estate Investments and the owner of the remaining 80% interest of Burnett Plaza
Associates, all of its interest in the joint venture for a purchase price of
approximately $51.2 million. The Burnett transaction was funded with proceeds
from our revolving credit facility and in part by the consummation of the
private placement of 613,750 common shares of beneficial interest with Salomon
Smith Barney Inc. The private placement closed in February 2002 with net
proceeds from the sale of the common shares totaling approximately $16.5 million
after underwriting discounts and commissions and before offering expenses.
Salomon Smith Barney Inc. was granted registration rights and a thirty-day
option to purchase up to an additional 92,063 common shares at $28.35 per common
share.

     In January 2002, we entered into an interest rate swap agreement with a
notional amount of $50.0 million which fixed 30-day LIBOR at 2.2775%. The new
swap, which matures January 2003, effectively fixes the interest rate at 3.6525%
on $50.0 million of variable rate borrowing.

     In January 2002, Dennis J. DuBois resigned as Executive Vice President and
Managing Director of the Southwest Region. Mr. DuBois was responsible for
overall asset management, leasing, property management and development for our
5.5 million square foot office portfolio in Dallas, Austin, Denver and Houston.
Effective January 2002, Christopher M. Hipps will be the new Managing Director
of the Southwest Region. Prior to January 2002, Mr. Hipps served as the Managing
Director of the West Region. Effective January 1, 2002, the West Region was
divided into the Northern California and Southern California Regions, and
Christopher B. Mahon was appointed as Managing Director of the Southern
California Region and Daniel K. Cushing was appointed as Managing Director of
the Northern California Region.

     On January 3, 2002, we repurchased all of the outstanding 9.45% Series C
Cumulative Redeemable Perpetual Preferred Units of our operating partnership for
approximately $50.6 million, including accrued and unpaid dividends. This was
funded using variable rate borrowings under our revolving credit facility.

Business and Growth Strategies

     Our primary objective is to maximize shareholder value through increases in
distributable cash flow per share and appreciation in the value of our common
shares. We intend to achieve this objective through a combination of external
and internal growth, while maintaining a conservative balance sheet and pursuing
a strategy of financial flexibility.

External Growth

     Development

     Development is a key component of our external growth strategy. We intend
to capitalize on our development capabilities by selectively developing and
redeveloping properties in markets with favorable current and projected
long-term growth characteristics and supply-demand imbalances. We control all
aspects of the development

                                       5

<PAGE>

process, including site selection, project concept, design and construction,
financing, leasing and property management. We intend to develop primarily
office properties on a build-to-suit basis, but we will also consider selective
opportunities for speculative development, when we deem conditions for such
development activity appropriate.

     In evaluating potential development opportunities, we rely on the
experience of our employees and on our internal research capabilities in
considering a number of factors, including:

     .    macro-economic issues that impact the market in which the development
          is to be located;
     .    location and competition in the property's market;
     .    occupancy of and demand for properties of a similar type in the same
          market; and
     .    the potential to generate revenue growth at or above levels of
          economic growth in the property's market.

     During 2001, we began development of one office property located in the San
Diego area containing 40,000 net rentable square feet. At December 31, 2001, we
had three office properties containing 445,000 square feet in various stages of
development. We completed and placed in-service four office properties
containing 592,000 net rentable square feet during 2001. The following tables
present our properties under development at December 31, 2001 and our
development properties placed in-service during 2001:

/(1)/ Net rentable square feet defines the area of a property for which a tenant
     is required to pay rent, which includes the actual rentable area plus a
     portion of the common areas of the property allocated to a tenant.

     See "Item 2. Properties" for additional information on our development
properties.

     Acquisitions

     Similar to developments, acquisitions are another key component of our
external growth strategy. We selectively pursue acquisitions in our core markets
when long-term yields make acquisitions attractive.

     We invest opportunistically and pursue assets that are:

     .    managed by us and owned by our existing management clients which
          become available for sale;
     .    performing at a level believed to be substantially below potential due

     .    held or controlled by short-term owners (such as assets held by
          insurance companies and financial institutions under regulatory
          pressure to sell); or
     .    properties with below market leases, which may be re-leased in the
          near term to improve cash flow.

     We believe that we are particularly well-positioned to acquire properties
because of our:

     .    presence in and knowledge of our 12 markets across the United States;
     .    a diversified base of approximately 1,100 tenants;
     .    existing relationships with 43 different management clients;
     .    access to capital as a public company, including our revolving credit
          facility;
     .    reputation as a buyer with the ability to execute complicated
          transactions;
     .    fully-integrated operations which allow rapid response to
          opportunities;
     .    UPREIT structure, which may allow sellers to defer tax consequences on
          sale; and
     .    relationships with real estate brokers, institutional owners, and
          third-party management clients, which often allow preferential access
          to opportunities.

     In evaluating potential acquisition opportunities, we rely on the
experience of our employees and on our internal research capabilities in
considering a number of factors, including:

     .    macro-economic issues that impact the market in which the property is
          located;
     .    location and competition in the property's market;
     .    occupancy of and demand for properties of a similar type in the same
          market;
     .    the construction quality and condition of the property;
     .    the potential for increased cash flow after benefiting from our
          renovations, refurbishment and upgrades;
     .    purchase price relative to replacement costs; and
     .    the potential to generate revenue growth at or above levels of
          economic growth in the property's market.

     Further, we believe that our development expertise enables us to identify
the potential for improvement in an acquisition opportunity, which might not be
apparent to a buyer without similar expertise.

     During the year ended December 31, 2001, we acquired seven office
properties totaling approximately 1.3 million net rentable square feet. The
following table sets forth the segment, market, month of acquisition, number of
buildings, net rentable square feet and purchase price of the properties we
acquired in 2001. See "Item 2. Properties" for additional information relating

Internal Growth

     We seek to maximize the profitability of our properties by renewing leases,
maintaining high occupancy rates, increasing rental revenues, and reducing
operating costs.

     We strive to achieve increases in rental revenues by negotiating leases
that include increases in rent during the lease term, by replacing expiring
leases with new leases at higher rental rates and by improving occupancy rates.
We also seek to renew existing leases, which reduces the costs of lease
rollovers, reduces rental revenue fluctuations and enhances long-term
relationships with national tenants that may have space needs in our other
markets.

     We strive to achieve reductions in operating costs by performing many
functions, e.g., engineering, tax and legal, in-house instead of hiring third
parties and by employing benchmarking and best practices methodologies. Our
benchmarking program compares operating costs and efficiencies of each property
with other office and industrial properties. Under the program, we conduct
periodic evaluations of key performance indicators at each building and compare
the results to a variety of benchmarks, e.g., specific buildings, portfolios,
regions and the industry. Our best practices methodology involves continuously
analyzing benchmarking data, investigating properties that perform better than
the norm and regularly disseminating and sharing information with respect to the
best practices employed at the better performing properties throughout our
management system. By employing these methodologies, we believe that we can
continue to capitalize on opportunities to reduce operating costs and operate
the properties more efficiently and effectively.

     We use centralized cash management, national alliances with service
providers, a sophisticated budgeting system and state-of-the-art information
systems to improve efficiency and increase profits. Training is provided through
Prentiss Properties University, a professional training program that increases
consistency within operations and communicates new technology and procedures
throughout our organization.

     Asset managers in each region develop a strategy and marketing position for
each property. Each property is evaluated using sophisticated valuation software
to determine the overall effect of property-level decisions such as lease
structures and capital expenditures on asset value. Asset managers also work
with property managers and engineers to determine where improvements, such as
lighting retrofits and energy management system upgrades, will maximize returns.

Third-Party Management

     At December 31, 2001, we, through Prentiss Properties Resources, Inc.,
managed or performed property-related services for 252 office, industrial and
other properties owned by 43 third-party management clients. These properties
are located throughout the United States and contain approximately 19.7 million
net rentable square feet.

     Our management business serves a broad base of clients, including major
financial institutions and pension funds, large corporate users, real estate
advisory firms and real estate investment groups. In addition to property
management and leasing, we offer our clients a full range of fee-based services,
including tenant construction, leasing, insurance, accounting, tax, acquisition,
disposition, facilities management, and corporate and asset management services.

Financing Strategy

     As of December 31, 2001, we had outstanding total indebtedness, including
our pro rata share of joint venture debt, of approximately $1.01 billion, or
approximately 43.4% of total market capitalization based on a common share price
of $27.45 per common share. As of March 20, 2002, we had the approximate
capacity to borrow up to an additional $226.0 million under our debt limitation
policy. The amount of indebtedness that we may incur, and the policies with
respect thereto, are not limited by our declaration of trust and bylaws, and are
solely within the discretion of our board of trustees, limited only by various
financial covenants in our credit agreements. Although it is our general policy
to limit combined indebtedness plus our pro rata share of joint venture debt so
that, at the time such debt is incurred, it does not exceed 50% of our total
market capitalization, we view ratios such as interest coverage and fixed charge
coverage as more stable and indicative measures of our ability to meet debt
obligations.

                                       8

<PAGE>

For the year ended December 31, 2001, our interest coverage (earnings before
interest, taxes and depreciation and amortization over interest expense) and
fixed charge coverage (earnings before interest, taxes and depreciation and
amortization over interest expense and perpetual preferred distributions)
totaled 3.16 and 2.68 times, respectively. Our credit agreements limit total
indebtedness to 55% of total assets and require an interest coverage ratio of at
least 2 to 1.

Competition

     We operate in five regions: Mid-Atlantic, Midwest, Southwest, Northern
California and Southern California and compete with many local, regional and
national competitors in the office and industrial sectors. These five regions
comprise 12 markets nationwide. The markets in which we operate are not
dominated by any one owner or by us. In each market we compete on a number of
factors including rental rates, tenant concessions, quality and location of
buildings, quality of property management, and other economic and non-economic
factors. Our major competitors in each region include the following companies:

Item 2. Properties

     At December 31, 2001, we owned interests in 146 properties totaling 17.6
million net rentable square feet with no individual property representing either
10% or more of our total assets at December 31, 2001 or gross revenues for the
year ended December 31, 2001. The properties consist of 108 office properties
comprising approximately 14.4 million net rentable square feet and 38 industrial
properties comprising approximately 3.2 million net rentable square feet. As of
December 31, 2001, all of these properties are wholly-owned by us (through our
subsidiaries), except the following:

          (1)  the Broadmoor Austin properties, which are held pursuant to a
               100% leasehold interest by Broadmoor Austin Associates, a joint
               venture, in which we own a 50% non-controlling interest;

          (2)  the Burnett Plaza property, which is owned by Burnett Plaza
               Associates, a joint venture, in which we owned a 20%
               non-controlling interest as of December 31, 2001;

          (3)  the 1676 International and 8260 Greensboro properties, which are
               owned by Tysons International Partners, a joint venture, in which
               we own a 25% non-controlling interest;

          (4)  One Northwestern Plaza, a property in which we own a 100%
               leasehold interest; and

          (5)  6600 Rockledge Drive, a property, in which we own a 100%
               leasehold interest.

     In March 2002, we purchased the remaining 80% interest of Burnett Plaza
Associates from an affiliate of Lend Lease Real Estate Investments.

          area plus a portion of the common areas of the property allocated to a
          tenant.
     /(F)/ Total base rent for the year ended December 31, 2001 includes the
          fixed rental amount due for the year ended December 31, 2001 under
          contractual lease obligations, which excludes (1) lease termination
          payments; (2) parking rent; (3) future contractual or contingent rent
          escalations; and (4) additional rent payable by tenants for items such
          as common area maintenance, real estate taxes and other expense
          reimbursements.

     At December 31, 2001, including our pro rata share of debt on our joint
venture properties, we had $814.2 million of mortgages on our properties, which
represents 80.8% of our total outstanding indebtedness. See "Item 7.
Management's Discussion and Analysis of Financial Condition and Results of
Operations - Liquidity and Capital Resources" for a discussion of mortgage debt
related to the properties.

     Our properties are leased to local, national and foreign companies engaged
in a variety of business including computer systems design, management,
insurance, broadcasting and telecommunications, legal services, and information
services. As of December 31, 2001, we had approximately 1,100 tenants, with the
following 7 tenants representing approximately 19% of our aggregate annualized
based rent and approximately 16% of our total net rentable square footage:
International Business Machines, Kaiser Foundation Health Plan, Verizon
Communications, MCI WorldCom, Northrop Grumman Corporation, Aspen Systems
Corporation and Moore North America. Leases typically contain provisions
permitting tenants to renew expiring leases at prevailing market rates.
Approximately 65% of our total leased rentable square footage is under full
service gross leases under which tenants typically pay for all real estate taxes
and operating expenses above those for an established base year or expense stop.
Our remaining square footage is under triple net and modified gross leases.
Triple net and modified gross leases are those where tenants pay not only base
rent, but also some or all real estate taxes and operating expenses of the
leased property. Tenants generally reimburse us the full direct cost, without
regard to a base year or expense stop, for use of lighting, heating and air
conditioning during non-business hours, and for on-site monthly employee and
visitor parking. We are generally responsible for structural repairs. Our
in-place leases have terms, on average, ranging from five to seven years in
length.

     The following table sets forth a 10-year schedule of the operating
properties' lease expirations for leases in place as of December 31, 2001.

     We are actively engaged in and have significant experience in the
development, redevelopment and renovation of office and industrial properties.
Subject to supply and demand, we expect to have the total projected costs of our
properties under development comprise approximately 10-15% of our total market
capitalization at any point in time. Due to current market conditions, we have
scaled back our development activity, and as a result, at December 31, 2001, we
had 445,000 net rentable square feet of properties under development with an
estimated development cost of $83.7 million, or 3.6% of our total market
capitalization. In addition to developing new properties, we are involved in
substantial levels of construction activity in the normal course of owning and
operating buildings. Such activity includes building out interior space for
tenants, expansions of existing buildings, and repairs necessary to upgrade or
maintain the quality of the buildings. The table below sets forth a schedule of
the segment, market, net rentable square feet and estimated cost of each of our
development properties.

/(1)/ Net rentable square feet defines the area of a property for which a tenant
      is required to pay rent, which includes the actual rentable area plus a
      portion of the common areas of the property allocated to a tenant.

/(2)/ As of December 31, 2001, we have incurred $64.4 million of the total
      estimated cost of our development properties.

Insurance

     We have and will keep in force comprehensive insurance, including
liability, fire, workers' compensation, extended coverage, rental loss and, when
available on reasonable commercial terms, flood and earthquake insurance, with
policy specifications, limits and deductibles customarily carried for similar
properties. We currently maintain insurance to cover environmental conditions
and business interruption if and when they occur. This policy covers both
governmental and third-party claims associated with the covered environmental
conditions. Our real property insurance policies exclude earthquake coverage for
properties located within California. As a result, we maintain a $100 million
blanket earthquake policy on the properties we own in Northern and Southern
California. Certain types of losses, however, generally of a catastrophic
nature, such as acts of war, are either uninsurable or the cost of obtaining
insurance is so high that it is more prudent to accept the risk of loss. Our
real property insurance policies put into effect before September 11, 2001 do
not expressly exclude coverage from hostile acts, except for acts of war.
Following the terrorist acts of September 11, 2001, however, insurance policies
purchased by us may expressly exclude hostile acts, and it may be impossible to
obtain insurance covering terrorist attacks. We may not be able to purchase
policies in the future with coverage limits and deductibles similar to those
that were available before September 11, 2001. In addition, we expect our
insurance premiums to increase in the future, which may have an adverse impact
on our cash flow. We believe that our properties are adequately insured in
accordance with industry standards.

Item 3. Legal Proceedings

     Neither we nor our affiliates (other than in a representative capacity) are
presently subject to any material litigation. To our knowledge, no litigation
has been threatened against us or our affiliates other than routine actions and
administrative proceedings, substantially all of which are expected to be
covered by liability insurance and which, in the aggregate, are not expected to
have a material adverse effect on our business or financial condition.

Item 4. Submission of Matters to a Vote of Security Holders

     No matter was submitted to a vote of our security holders during the fourth
quarter of 2001 through the solicitation of proxies or otherwise.

Market Information

     Our common shares commenced trading on the NYSE on October 17, 1996 under
the symbol "PP." As of March 20, 2002, the last reported sales price per common
share on the NYSE was $29.40 per common share. The following table sets forth
the high and low sales price per common share reported on the NYSE as traded for
the periods indicated.

Holders

     At March 20, 2002, we had approximately 480 holders of record and
approximately 7,500 beneficial owners of our common shares. As of March 20,
2002, all of our 3,773,585 Series D Preferred Shares, which are convertible into
our common shares subject to certain limitations, were held by Security Capital
Preferred Growth, Incorporated. In addition, the units of limited partnership
interest in the operating partnership, which are redeemable for common shares
subject to limitations, were held by 22 entities or persons.

     In order to comply with certain requirements related to qualification as a
REIT, our organizational documents limit the number of outstanding common shares
that may be owned by any single person or affiliated group to 8.5% of the
outstanding common shares (other than Michael V. Prentiss, for whom the
ownership limitation is 15%, and Security Capital Preferred Growth,
Incorporated, for whom the ownership limitation is 11%).

Dividends

     We have adopted a policy of paying regular quarterly distributions on our
common shares and cash distributions have been paid on our common shares with
respect to each such period since our inception. The following table sets forth
information regarding the declaration and payment of distributions by us in 2001
and 2000.

     For tax purposes, the foregoing distributions represent an approximate 8.9%
and 9.2% return of capital in 2001 and 2000, respectively. In order to maintain
our qualification as a REIT, beginning in 2001, we must make annual
distributions to our shareholders of at least 90% of our taxable income,
excluding net capital gains. During the year ended December 31, 2001, we
declared distributions totaling $2.09 per share. Prior to 2001, we were required
to make annual distributions to our shareholders of at least 95% of our taxable
income, excluding net capital gains. During the year ended December 31, 2000, we
declared distributions totaling $1.895 per share. Under certain circumstances we
may be required to make distributions in excess of cash available for
distribution in order to meet such REIT distribution requirements. In such
event, we presently would expect to borrow funds, or to sell assets for cash, to
the extent necessary to obtain cash sufficient to make the distributions
required to retain our qualification as a REIT for federal income tax purposes.

     We declared a cash distribution for the first quarter of 2002 in the amount
of $.535 per share, payable on April 12, 2002 to holders of record on March 29,
2002. We currently anticipate that we will maintain at least the current
distribution rate for the immediate future, unless actual results of operations,
economic conditions or other factors differ from our current expectations.
Future distributions, if any, paid by us will be at the discretion of our board
of trustees and will depend on our cash flow, our financial condition, capital
requirements, the annual distribution requirements under the REIT provisions of
the Internal Revenue Code and such other factors as our board of trustees deems
relevant.

/(1)/ Represents the limited partners' interest in the operating partnership as
     well as the limited partners' interest in certain real estate partnerships.
/(2)/ EBITDA means operating income before mortgage and other interest expense,
     income taxes, depreciation and amortization. We believe that EBITDA is
     useful to investors as an indication of our ability to service debt and pay
     cash distributions. EBITDA, as calculated by us, is not comparable to
     EBITDA reported by other REITs that do not define EBITDA exactly as we do.
     EBITDA does not represent cash generated from operating activities in
     accordance with generally accepted accounting principles, and should not be
     considered as an alternative to operating income or net income as an
     indicator of performance or as an alternative to cash flows from operating
     activities as an indicator of liquidity. Our EBITDA for the respective

     losses) from sales of property, plus depreciation and amortization on real
     estate assets, and after adjustments for unconsolidated partnerships, joint
     ventures and subsidiaries. We believe that funds from operations is helpful
     to investors as a measure of the performance of an equity REIT because,
     along with cash flow from operating activities, financing and investing
     activities, it provides investors with an indication of our ability to
     incur and service debt, to make capital expenditures and to fund other cash
     needs. Our funds from operations is not comparable to funds from operations
     reported by other REITs that do not define funds from operations exactly as

     operating results, funds from operations should be examined in conjunction
     with net income as presented in our audited Consolidated Financial
     Statements and notes thereto included elsewhere in this Form 10-K. Funds

     distributions. Our funds from operations for the respective periods is

Item 7. Management's Discussion and Analysis of Financial Condition and Results
        of Operations

     The following discussion and analysis of financial condition and results of
operations should be read in conjunction with our "Selected Financial and
Operating Data" and our historical Consolidated Financial Statements and related
notes thereto. Historical results set forth in our "Selected Financial and
Operating Data," and Consolidated Financial Statements should not be taken as an
indication of our future operations.

Overview

     We are a real estate company organized as a Maryland REIT. We acquire, own,
manage, lease, develop and build primarily office properties throughout the
United States. We operate principally through our operating partnership,
Prentiss Properties Acquisition Partners, L.P. and its subsidiaries, and a
management company, Prentiss Properties Resources, Inc. and its subsidiaries. As
of December 31, 2001, we owned interests in a diversified portfolio of 108
office and 38 industrial properties containing in the aggregate 17.6 million net
rentable square feet.

<PAGE>

     The discussion and analysis which follows focuses on our reportable
segments as we believe that the segment analysis provides the most effective
means of understanding our results of operations. During 2001, we had two
significant changes to our reportable segments including (1) the disposition of
our Northeast regional office and (2) the division of our West Region into
separate Northern and Southern California Regions. For comparative purposes, the
results of operations, of prior years, attributable to our West Region have been
reclassified to separate Northern and Southern California Regions.

     The table below presents a summary of our property transactions from
January 1, 1999 through December 31, 2001:

Critical Accounting Policies

     Our discussion and analysis of financial condition and results of
operations is based upon our Consolidated Financial Statements. Our Consolidated
Financial Statements include the accounts of Prentiss Properties Trust, Prentiss
Properties Acquisition Partners, L.P. and other subsidiaries. The preparation of
financial statements in conformity with accounting principles generally accepted
in the United States of America requires us to make estimates and assumptions
that affect the reported amounts of assets and liabilities and the disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses for the reporting period. Actual
results could differ from our estimates.

     The estimates used in the preparation of our Consolidated Financial
Statements are more fully described in Note (2) to our Consolidated Financial
Statements. However, certain of our significant accounting policies are
considered critical accounting policies due to the increased level of
assumptions used or estimates made in determining their impact on our
Consolidated Financial Statements.

                                       21

<PAGE>

     We consider our critical accounting policies to be those used in the
determination of the reported amounts and disclosure related to the following:

          (1)  Impairment of long-lived assets and the long-lived assets to be
               disposed of;

          (2)  Allowance for doubtful accounts;

          (3)  Depreciable lives applied to real estate assets and improvements
               to real estate assets; and

          (4)  Fair value of derivative instruments.

Impairment of long-lived assets and long-lived assets to be disposed of

     Real estate and leasehold improvements are classified as long-lived assets
held for sale or long-lived assets to be held and used. In accordance with
Statement of Financial Accounting Standards No. 121, "Accounting for the
Impairment of Long-Lived Assets and the Long-Lived Assets to be Disposed of," we
record assets held for sale at the lower of the carrying amount or fair value
less cost to sell. With respect to assets classified as held and used, we
periodically review these assets to determine whether our carrying amount will
be recovered from the undiscounted future operating cash flows and we recognize
an impairment loss to the extent the carrying amount is not recoverable and
exceeds its fair value. Our determination of future operating cash flows
requires us to make assumptions related to future rental rates, tenant
concessions, operating expenditures, property taxes and capital improvements.

Allowance for doubtful accounts

     Accounts receivable are reduced by an allowance for amounts that may become
uncollectible in the future. Our receivable balance is comprised primarily of
rents and operating cost recoveries due from tenants as well as accrued rental
rate increases to be received over the life of the in-place leases. We regularly
evaluate the adequacy of our allowance for doubtful accounts considering such
factors as credit quality of our tenants, delinquency of payment, historical
trends and current economic conditions. Actual results may differ from these
estimates under different assumptions or conditions.

Depreciable lives applied to real estate assets and improvements to real estate
assets

     Depreciation on buildings and improvements is provided under the
straight-line method over an estimated useful life of 30 to 40 years for office
buildings and 25 to 30 years for industrial buildings. Significant betterments
made to our real estate assets are capitalized and depreciated over the
estimated useful life of the betterment.

Fair value of derivative instruments

     In the normal course of business, we are exposed to the effect of interest
rate changes. We limit these risks by following established risk management
policies and procedures including the use of derivatives. For interest rate
exposures, derivatives are used primarily to hedge against rate movements on our
related debt. We are required to recognize all derivatives as either assets or
liabilities in the statement of financial position and to measure those
instruments at fair value. Changes in fair value will affect either
shareholders' equity or net income depending on whether the derivative
instrument qualifies as a hedge for accounting purposes.

     To determine the fair values of derivative instruments, we use a variety of
methods and assumptions that are based on market conditions and risks existing
at each balance sheet date. For the majority of financial instruments including
most derivatives, standard market conventions and techniques such as discounted
cash flow analysis, option pricing models, replacement cost, and termination
cost are used to determine fair value. All methods of assessing fair value
result in a general approximation of value, and such value may never actually be
realized.

Results of Operations

     As illustrated in the table above, from January 1, 1999 through December
31, 2001, we had significant property transactions including property
acquisitions, dispositions and developments. During this three-year period our
office

                                       22

<PAGE>

portfolio increased from 13.8 million to 14.4 million net rentable square feet
while our industrial portfolio decreased from 7.1 million to 3.2 million net
rentable square feet. As a result of the significant property transactions, the
comparison of the years provides only limited information regarding our
operations as currently constituted. Therefore, in our comparison of operating
results for the years ended December 31, 2001, 2000 and 1999 we show changes
resulting from our total portfolio and our same-store property portfolio, i.e.,
those properties owned during the entirety of the periods being compared.

     /(1)/ The 117 properties included in our same-store property portfolio
          excludes 123 North Wacker Drive, a 537,000 net rentable square foot
          office property in downtown Chicago. The property was taken out of
          service at the end of September 2001 to convert the building from a
          single tenant building to its future intended use as a multi-tenant
          building.

     Rental Income. Rental income increased by $3.5 million, or 1.0%, to $339.4
million in 2001 from $335.9 million in 2000 partially as a result of properties
acquired or development properties becoming operational subsequent to January 1,
2000, offset by properties that were sold during the two years ended December
31, 2001. Rental income for the same-store property portfolio increased by $12.3
million, or 4.8%, from $254.7 million for the year ended December 31, 2000 to
$267.0 million for the year ended December 31, 2001 primarily as a result of an
increase in straight-lined rent achieved from new leases exceeding that from
expiring leases. The increase in our same-store property portfolio was
attributable to our five regions as follows:

     Property Operating and Maintenance. Property operating and maintenance
increased by $908,000, or 1.2%, to $78.9 million in 2001 from $78.0 million in
2000 partially as a result of properties acquired or development properties
becoming operational subsequent to January 1, 2000, offset by properties that
were sold during the two years ended December 31, 2001. Property operating and
maintenance for the same-store property portfolio increased by $2.4 million, or
3.9%, from $60.6 million for the year ended December 31, 2000 to $63.0 million
for the year ended December 31, 2001 primarily as a result of an increase of
$1.3 million in utility expenses accompanied by a general increase in expenses
attributable to operating and maintenance cost of the properties. The increase
in our same-store property portfolio was attributable to our five regions as
follows:

     Real Estate Taxes. Real estate taxes decreased by $45,000, or less than
1.0%, to $38.4 million in 2001 partially as a result of properties acquired or
development properties becoming operational subsequent to January 1, 2000,
offset by properties that were sold during the two years ended December 31,
2001. Real estate taxes for the same-store property portfolio increased by $1.1
million, or 3.8% from $29.0 million for the year ended December 31, 2000 to
$30.1 million for the year ended December 31, 2001 primarily as a result of the
reassessment of certain property values by taxing authorities in each of our
regions. The increase in our same-store property portfolio was attributable to
our five regions as follows:

     General and Administrative and Personnel Costs. General and administrative
and personnel costs increased by $606,000, or 6.2%, from $9.8 million in 2000 to
$10.4 million in 2001 due to (1) the amortization of restricted share grants
issued in March 2000 and 2001; (2) an increase in compensation expense resulting
from the 2000 calendar year bonus compensation, paid in March 2001, exceeding
the estimate of such cost accrued at December 31, 2000; partially offset by (3)
a decrease in general and administrative and personnel cost as a result of the
sale of our Northeast Region.

     Interest Expense. Interest expense decreased by $6.7 million, or 9.5%, to
$64.5 million in 2001 from $71.2 million in 2000 primarily as a result of the
decrease in mortgages and notes payable from $1.01 billion at January 1, 2001 to
$907.7 million at December 31, 2001. The decrease in mortgages and notes payable
resulted from (1) the repayment of mortgages and notes payable with proceeds
generated from our asset disposition activity and (2) the assumption of certain
mortgages and notes payable by the purchasers of assets disposed of during the
period partially offset by proceeds used for assets acquired during the period.

     Depreciation and Amortization. Depreciation and amortization increased by
$869,000, or 1.4%, to $64.3 million in 2001 from $63.4 million in 2000 partially
as a result of properties acquired or development properties becoming
operational subsequent to January 1, 2000, offset by properties that were sold
during the two years ended December 31, 2001. Depreciation and amortization for
the same-store property portfolio increased by $2.0 million, or 4.2%, from $48.3
million for the year ended December 31, 2000 to $50.3 million for the year ended
December 31, 2001 which is attributable to increases in depreciation and
amortization of leasehold improvements which results from leasing activity
incurred subsequent to the acquisition of the properties. The increase in our
same-store property portfolio was attributable to our five regions as follows:

                      Number of                       Increase/

     Equity in Income of Joint Ventures and Unconsolidated Subsidiaries. Equity
in income of joint ventures and unconsolidated subsidiaries decreased by
$712,000, or 18.5%, from $3.8 million for the year ended December 31, 2000 to
$3.1 million for the year ended December 31, 2001. The decrease was attributable
to a decrease of $1.4 million representing our share of the decrease in net
income of the management company, offset by an increase of $441,000 representing
our proportionate share of the increase in net income from the Burnett Plaza
property and $173,000 representing our proportionate share of net income of
Tysons International Partners, a 25% interest we acquired in April 2001 from
Brandywine Realty Trust. The decrease in net income of the management company
resulted from a decrease of management fees and other fee income earned,
partially offset by a decrease in general and administrative and personnel costs
of the management company.

     Gain on Sales. Gain on sales increased by $13.7 million to $13.9 million in
2001 from $221,000 in 2000. It is our strategy to obtain the maximum value from
each of our properties, which is occasionally achieved through the

                                       25

sale of a property. During the year ended December 31, 2001, we sold 42
properties totaling 2.8 million net rentable square feet compared to 27
properties totaling 1.7 million net rentable square feet sold during 2000.

     Loss on Investment in Securities. In November 1999, we invested $1.0
million in Urban Media Communications Corporation, a provider of broad band
internet access to tenants of commercial office buildings. As a result of Urban
Media's purported inability to raise funding necessary to continue day to day
operations, in December 2000, we recognized a loss equal to 100% of our
investment in Urban Media.

     Minority Interests. Minority interests increased by $1.9 million, or 12.4%,
from $15.7 million for the year ended December 31, 2000 to $17.6 million for the
year ended December 31, 2001. The increase was primarily attributable to the
minority interest holders share of the increase in net income before minority
interest of $34.8 million from 2000 to 2001 accompanied by the income allocation
from the issuance of 200,000, $50 par value, Series E Preferred Units in April
2001.

Comparison of the Year Ended December 31, 2000 to the Year Ended December 31,
1999

     During 2001, we disposed of all of our assets in the suburban Philadelphia
area and as a result exited our Northeast Region. However, during the two-year
period ended December 31, 2000, we had operations in our Northeast Region and as
a result, the comparison of operating information for the two-year period ended
December 31, 2000 includes six operating segments as follows: (1) Mid-Atlantic;
(2) Midwest; (3) Northeast; (4) Southwest; (5) Northern California; and (6)
Southern California.

     The table below presents the actual statement of operations for our total
portfolio and selected operating information for the 143 properties acquired or
placed in service on or prior to January 1, 1999 that remained in our portfolio
through December 31, 2000 (which comprise our same-store property portfolio for
the two year period ended December 31, 2000):

     Rental Income. Rental income increased by $38.7 million, or 13.0% to $335.8
million in 2000 from $297.1 million in 1999 primarily as a result of properties
acquired or development properties becoming operational subsequent to January 1,
1999, offset by properties that were sold during the two years ended December
31, 2000. Rental income for the same-store property portfolio increased by $8.9
million, or 3.5%, from $251.6 million for the year ended December 31, 1999 to
$260.5 million for the year ended December 31, 2000 primarily as a result of an
increase in straight-lined rent achieved from new leases exceeding that from
expiring leases. The increase in our same-store property portfolio was
attributable to our six regions as follows:

     Property Operating and Maintenance. Property operating and maintenance
increased by $8.4 million, or 12.1%, to $78.0 million in 2000 from $69.6 million
in 1999 primarily as a result of properties acquired or development properties
becoming operational subsequent to January 1, 1999, offset by properties that
were sold during the two years ended December 31, 2000. Property operating and
maintenance for the same-store property portfolio increased by $3.1 million, or
5.2%, from $59.7 million for the year ended December 31, 1999 to $62.8 million
for the year ended December 31, 2000 primarily as a result of a $2.4 million

$700,000 increase in utility expenses. The increase in our same-store property
portfolio was attributable to our six regions as follows:

     Real Estate Taxes. Real estate taxes increased by $4.2 million, or 12.3%,
to $38.4 million in 2000 from $34.2 million in 1999 primarily as a result of
properties acquired or development properties becoming operational subsequent to
January 1, 1999, offset by properties that were sold during the two years ended
December 31, 2000. Real estate taxes for the same-store property portfolio
decreased by $902,000, or 3.0% from $29.8 million for the

year ended December 31, 1999, to $28.9 million for the year ended December 31,
2000 primarily as a result of the reassessment of certain property values by
taxing authorities in each of our regions. The decrease in our same-store
property portfolio was attributable to our six regions as follows:

     General and Administrative and Personnel Costs. General and administrative
and personnel costs increased by $947,000, or 10.7%, from $8.8 million in 1999
to $9.8 million in 2000. The increase is primarily attributable to the
amortization of restricted share grants issued during the year ended December
31, 2000. The general and administrative costs remained constant at 2.9% of our
revenues.

     Interest Expense. Interest expense increased by $11.9 million, or 20.0%, to
$71.2 million from $59.3 million primarily as a result of the increase in
mortgages and notes payable from $800.3 million at January 1, 1999 to $896.8
million at December 31, 1999 to $1.0 billion at December 31, 2000. The increase
in mortgages and notes payable resulted from the increase of $204.9 million in
real estate from January 1, 1999 to December 31, 2000 and $69.3 million of
proceeds used to repurchase common shares during the two year period, offset by
proceeds received from the issuance by the operating partnership of 2,000,000,
$25 par value, Series C Perpetual Preferred Units in September 1999.

     Depreciation and Amortization. Depreciation and amortization increased by
$8.9 million, or 16.3%, to $63.4 million in 2000 from $54.5 million in 1999
primarily as a result of properties acquired or development properties becoming
operational subsequent to January 1, 1999, offset by properties that were sold
during the two years ended December 31, 2000. Depreciation and amortization for
the same-store property portfolio, increased by $3.4 million, or 7.9%, from
$43.3 million for the year ended December 31, 1999 to $46.7 million for the year
ended December 31, 2000 which is attributable to increases in depreciation and
amortization of leasehold improvements which results from leasing activity
incurred subsequent to the acquisition of the properties. The increase in our
same-store property portfolio was attributable to our six regions as follows:

     Equity in Income of Joint Ventures and Unconsolidated Subsidiaries. Equity
in income of joint ventures and unconsolidated subsidiaries decreased by
$451,000, or 10.5%, from $4.3 million for the year ended December 31, 1999 to
$3.8 million for the year ended December 31, 2000. The decrease was attributable
to a decrease of $1.2 million representing our share of the decrease in net
income of the management company, offset by an increase of $461,000 representing
our proportionate share of the increase in net income from the Burnett Plaza
property which was acquired in March 1999 and $327,000 representing our
proportionate share of net income of PPS Partners LLC, a 75% interest we
acquired in early 2000. The decrease in net income of the management company
resulted from a decrease of management fees and other fee income earned,
partially offset by a decrease in general and administrative and personnel costs
of the management company.

     Gain on Sales. Gain on sales decreased by $15.9 million, to $221,000 in
2000 from $16.1 million in 1999. It is our strategy to obtain the maximum value
from each of our properties, which is occasionally achieved through the sale of
a property. During the year ended December 31, 2000, we sold 27 properties
totaling 1.7 million net rentable square feet as compared to 45 properties
totaling 2.5 million net rentable square feet and two land parcels totaling
27.06 acres sold during 1999.

     Loss on Investment in Securities. In November 1999, we invested $1.0
million in Urban Media Communications Corporation, a provider of broad band
internet access to tenants of commercial office buildings. As a result of Urban
Media's purported inability to raise funding necessary to continue day to day
operations, in December 2000, we recognized a loss equal to our investment in
Urban Media.

     Minority Interests. Minority interests increased by $2.9 million, or 22.9%,
from $12.7 million for the year ended December 31, 1999 to $15.6 million for the
year ended December 31, 2000. The increase was primarily attributable to the
income allocation from the issuance by the operating partnership of 2,000,000,
$25 par value, Series C Perpetual Preferred Units in September 1999, offset by
the minority interest holders share of the decrease in income before minority
interest of $8.0 million from 1999 to 2000.

Liquidity and Capital Resources

     Cash and cash equivalents were $5.8 million and $5.5 million at December
31, 2001 and December 31, 2000, respectively. The increase in cash and cash
equivalents is a result of cash flows provided by operating activities exceeding
those used in investing and financing activities.

     Cash Provided by Operating Activities. Net cash provided by operating
activities was $157.3 million for the year ended December 31, 2001 compared to
$158.1 million for the year ended December 31, 2000.

     Cash Used in Investing Activities. Net cash used in investing activities
decreased from $169.4 million for the year ended December 31, 2000 to $49.7
million for the year ended December 31, 2001. The decrease in cash used in
investing activities is primarily due to a decrease of cash used in the purchase
and development of real estate of $25.4 million accompanied by an increase of
$90.5 million in cash generated from the sale of real estate from 2000 to 2001.

     Cash (Used in) Provided by Financing Activities. During 2001, we had net
cash used in financing activities of $107.2 million as compared to $3.4 million
of cash provided by financing activities for the year ended December 31, 2000.
The change is primarily attributable to net repayments of mortgages and notes
payable of $8.3 million during 2001 compared to net borrowings of mortgages and
notes payable of $111.0 million during 2000, accompanied by an $11.8 million
increase in distributions paid, partially offset by an $18.8 million decrease in
cash used for the purchase of treasury shares.

     As of December 31, 2001, we had outstanding total indebtedness, including
our pro rata share of joint venture debt of approximately $1.01 billion, or
approximately 43.4% of total market capitalization based on a common share price
of $27.45 per common share. Our policy is to limit combined indebtedness plus
our pro rata share of joint venture debt and construction loans so that at the
time such debt is incurred, it does not exceed 50% of the our total market
capitalization. As of December 31, 2001, we had the approximate capacity to
borrow up to an additional $308.8 million under the debt limitation and the
various restrictions in our credit agreements. The amount of indebtedness that
we may incur, and the policies with respect thereto, are not limited by our
declaration of trust and bylaws, and are solely within the discretion of our
board of trustees limited only by various financial covenants in our credit
agreements.

     We have in place a $300 million unsecured revolving credit facility with a
group of 12 banks. The facility which was renewed in May 2000 matures in May
2003. The facility has an initial interest rate of LIBOR plus 137.5 basis
points. Additionally, we are required to pay an average unused commitment fee of
25 basis points per annum if the unused portion of the credit facility is
greater than $200 million. The fee is reduced to 20 basis points per annum if
the unused portion is less than or equal to $200 million, but greater than $100
million. The fee is further reduced to 15 basis points per annum if the unused
portion is less than or equal to $100 million. During the year, we

                                       29

had net repayments under our credit facility of $24.0 million and an outstanding
balance of $118.5 million at December 31, 2001, resulting in an available
balance of $181.5 million.

     As of December 31, 2001, we have non-controlling partnership interest in
three separate real estate joint ventures which have in the aggregate $258.7
million of non-recourse mortgage debt. The mortgage debt of each venture is
collateralized by the real estate property or properties within each venture,
the net book value of which totaled $265.9 million at December 31, 2001. Our
proportionate share of the non-recourse mortgage debt totaled $99.9 million at
December 31, 2001.

     The following table sets forth our mortgages and notes payable, including
our pro rata share of joint venture debt, as of December 31, 2001:

/(1)/ We own a 50% non-controlling interest in the entity that owns the
     Broadmoor Austin properties, which interest is accounted for using the
     equity method of accounting. The amount shown reflects our proportionate
     share of the non-recourse mortgage indebtedness collateralized by the
     properties.

/(2)/ As of December 31, 2001, we owned a 20% non-controlling interest in the
     entity that owns the Burnett Plaza property, which interest is accounted
     for using the equity method of accounting. The amount shown reflects our
     proportionate share of the non-recourse mortgage indebtedness
     collateralized by the property. In January 2002, we, through, Prentiss
     Properties Acquisition Partners, L.P., purchased the Burnett Plaza
     Associates loan in the

     principal amount of $47.0 million from Teachers Insurance and Annuity
     Association of America. In March 2002, we purchased the remaining 80%
     interest of Burnett Plaza Associates from an affiliate of Lend Lease Real
     Estate Investments.

/(3)/ The Term Loan is collateralized by the following four properties: Willow
     Oaks I & II (two properties), 8521 Leesburg Pike and the IBM Call Center.

/(4)/ The PPREFI Portfolio Loan is collateralized by the following 36
     properties: the Los Angeles industrial properties (18 properties), the
     Chicago industrial properties (four properties), the Cottonwood Office
     Center (three properties), Park West E1 and E2 (two properties), One

     Plaza II, 1717 Deerfield Road, 2411 Dulles Corner Road, 4401 Fair Lakes
     Court, the WestPoint Office Building and the PacifiCare Building.

/(5)/ We own a 25% non-controlling interest in the entity that owns the 1676
     International and 8260 Greensboro properties, which interest is accounted
     for using the equity method of accounting. The amount shown reflects our
     proportionate share of the non-recourse mortgage indebtedness
     collateralized by the properties.

     The majority of our fixed rate secured debt contains prepayment provisions
based on the greater of a yield maintenance penalty or 1.0% of the outstanding
loan amount. The yield maintenance penalty essentially compensates the lender
for the difference between the fixed rate under the loan and the yield that the
lender would receive if the lender reinvested the prepaid loan balance in U.S.
Treasury Securities with a similar maturity as the loan.

     Under our loan agreements, we are required to satisfy various affirmative
and negative covenants, including limitations on total indebtedness, total
collateralized indebtedness and cash distributions, as well as obligations to
maintain certain minimum tangible net worth and certain minimum interest
coverage ratios. Our credit agreements limit total indebtedness to 55% of total
assets and require a debt service coverage ratio of at least 2 to 1. Our credit
agreements provide for a 30-day period to cure a default caused by our failure
to punctually and properly perform, observe and comply with the covenants
contained therein. The agreements also provide for an additional 75-day period
if such failure is not capable of being cured within 30-days and we are
diligently pursuing the cure thereof. We were in compliance with these covenants
at December 31, 2001.

     To manage interest rate risk, we may employ options, forwards, interest
rate swaps, caps and floors or a combination thereof depending on the underlying
interest rate exposure. We undertake a variety of borrowings: from revolving
credit facilities, to medium- and long-term financings. To manage overall
interest rate exposure, we use interest rate instruments, typically interest
rate swaps, to convert a portion of our variable rate debt to fixed rate debt.
Interest rate differentials that arise under these swap contracts are recognized
as interest expense over the life of the contracts.

     We may employ forwards or purchased options to hedge qualifying anticipated
transactions. Gains and losses are deferred and recognized in net income in the
same period that the anticipated transaction occurs, expires or is otherwise
terminated.

     The following table summarizes the notional values and fair values of our
derivative financial instruments. The notional value provides an indication of
the extent of our involvement in these instruments as of the balance sheet date,
but does not represent exposure to credit, interest rate or market risks.

     Our properties require periodic investments of capital for tenant-related
capital expenditures and for general capital improvements. For the year ended
December 31, 2001, our recurring non-incremental revenue-generating capital
expenditures totaled approximately $24.3 million. Our recurring non-incremental
revenue-generating capital expenditures were attributable to our six regions as
follows: (1) Mid-Atlantic-$4.4 million; (2) Midwest-$3.1 million; (3)
Northeast-$0.4 million; (4) Southwest-$5.6 million; (5) Northern California-$6.4
million; and (6) Southern California-$4.4 million.

     We have considered our short-term liquidity needs and the adequacy of
adjusted estimated cash flows and other expected liquidity sources to meet these
needs. We believe that our principal short-term liquidity needs are to fund
normal recurring expenses, debt service requirements and the minimum
distributions required to maintain our REIT qualification under the Internal
Revenue Code. We expect to make distributions to our shareholders primarily
based on distributions from the operating partnership. The operating
partnership's income will be derived from operating activities which include
rental revenues and operating expense reimbursements from tenants and, to a
limited extent, from fees generated by our office and industrial real estate
management service business.

     We anticipate that these needs will be fully funded from cash flows
provided by operating activities and, when necessary to fund shortfalls
resulting from the timing of collections of accounts receivable in the ordinary
course of business, from our revolving credit facility. In the event that our
cash flow needs exceed our cash flows provided by operating activities, we may
be forced to sell real estate properties to fund such cash flow needs.

     We expect to meet our long-term liquidity requirements for the funding of
activities, such as development, property acquisitions, scheduled debt
maturities, major renovations, expansions and other non-recurring capital
improvements through long-term secured and unsecured indebtedness and through
the issuance of additional debt and equity securities. We also intend to use
proceeds from our revolving credit facility to fund property acquisitions,
development, redevelopment, expansions and capital improvements on an interim
basis.

     We have contractual obligations and commercial commitments including
mortgages and notes payable, ground lease obligations and letters of credit. The
table below presents, as of December 31, 2001, our future scheduled principal
repayments of mortgages and notes payable and ground lease obligations,
including our pro rata share of debt and ground lease obligations of our of

Funds from Operations

     Funds from operations, as defined by the National Association of Real
Estate Investment Trusts, means net income, computed in accordance with
generally accepted accounting principles excluding extraordinary items (as
defined by generally accepted accounting principles) and gains (or losses) from
sales of property, plus depreciation and amortization on real estate assets, and
after adjustments for unconsolidated partnerships, joint ventures and
subsidiaries. We believe that funds from operations is helpful to investors as a
measure of the performance of an equity REIT because, along with cash flow from
operating activities, financing and investing activities, it provides investors
with an indication of our ability to incur and service debt, to make capital
expenditures and to fund other cash needs. Our funds from operations is not
comparable to funds from operations reported by other REITs that do not define
funds from operations exactly as we do. We believe that in order to facilitate a
clear understanding of our operating results, funds from operations should be
examined in conjunction with net income as presented in our audited Consolidated
Financial Statements and notes thereto included elsewhere in this Form 10-K.
Funds from operations does not represent cash generated from operating
activities in accordance with generally accepted accounting principles and
should not be considered as an alternative to net income as an indication of our
performance or to cash flows as a measure of liquidity or ability to make
distributions. Our funds from operations for the respective periods are
calculated as follows:

     Funds from operations increased by $9.6 million for the year ended December
31, 2001 from the year ended December 31, 2000 and increased by $9.6 million for
the year ended December 31, 2000 from the year ended December 31, 1999 as a
result of the factors discussed in the analysis of operating results.

Recently Issued Accounting Standards

     In August 2001, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets." The statement which is effective for financial
statements issued for fiscal years beginning after December 15, 2001 and interim
periods within those fiscal years, addresses financial accounting and reporting
for the impairment or disposal of long-lived assets. The impact from the
implementation of this statement, which we believe will not have a material
impact on our financial statements, will be dependent upon (1) which if any of
our assets qualify as held for sale at January 1, 2002 or at any point in time
thereafter; (2) whether the carrying amount of such assets determined to be held
for sale is greater than the fair value less cost of sale of the assets; and (3)
whether the carrying amount of assets determined not to be held for sale is
recoverable from the undiscounted future cash flows from operations and from the
eventual sale of the assets.

Application of and Changes in Law Regarding Ownership of Subsidiaries and
Qualifications as a REIT

     For federal income tax purposes, we were organized and have operated in
conformity with the requirements for qualification as a REIT under the Internal
Revenue Code of 1986, as amended, beginning with our taxable year ending
December 31, 1996 and through the date hereof. The Internal Revenue Code sets
forth various income, asset, ownership, and distribution tests with respect to
which a REIT must comply in order to maintain its status as a REIT. Although the
Internal Revenue Service, based upon its interpretation of the relevant judicial
and administrative authorities, may take the position that a REIT has failed a
particular qualification test, the facts and circumstances upon which such a
determination would be based are controlled by the REIT. To the extent that a
REIT does not comply with a particular test, the decision to take an action that
would prevent compliance or to not take an action that would have allowed
compliance will be directly within the control of the REIT. We are unaware of
any instance in which a REIT has lost its qualification as a REIT due to the
failure of one of the statutory qualification tests under the Internal Revenue
Code. We believe that our current and proposed method of operation will enable
us to continue to qualify as a REIT.

     The REIT Modernization Act effective for 2001 and later years, contains
several provisions affecting REITs. The REIT Modernization Act allows a
subsidiary to perform services for tenants without disqualifying the rents
received (as under prior law). These subsidiaries, called Taxable REIT
Subsidiaries, are subject to taxation and are limited in the amount of debt and
rental payments between the REIT and the Taxable REIT Subsidiaries. The fair
market value of all Taxable REIT Subsidiaries' securities cannot exceed 20% of
the REIT's fair market value. Existing subsidiaries could be grandfathered in a
one-time tax-free conversion. They are not subject to these limitations, unless
engaging in a new line of business or increasing assets. If either of these
events occurs, new restrictions on debt and rental payments will apply to these
entities as well. The REIT Modernization Act also reduced the REIT taxable
income distribution requirement from 95% to 90%.

Inflation

     Most of the leases on our properties require tenants to pay increases in
operating expenses, including common area charges and real estate taxes, thereby
reducing the impact on us of the adverse effects of inflation. Leases also vary
in term from one month to 17 years, further reducing the impact on us of the
adverse effects of inflation.

RISK FACTORS

          An investment in us involves various risks. The following describes
factors that in some cases may have affected, and in the future could affect,
our actual operating results and could cause such results to differ materially
from those in any forward-looking statements. This list is not necessarily
exhaustive, and new risk factors emerge from time to time. We cannot assure you
that the factors described below are all of the material risks to us at any

                                       34

<PAGE>

specific point in time. You should carefully consider the following factors
which qualify in their entirety each forward-looking statement.

Risks Related to General Business Operations

The geographic concentration of our properties in markets which are in economic
decline could have a material adverse effect on operating performance.

          Properties located in the Mid-Atlantic, Midwest, Southwest, Northern
California and Southern California provided approximately 27%, 20%, 28%, 13% and
9%, respectively, of total revenues for the year ended December 31, 2001. Like
other real estate markets, these commercial real estate markets have experienced
economic downturns in the past, and future declines in any of these economies or
real estate markets could adversely affect our cash available for distribution.
Our financial performance and ability to make distributions to our shareholders
are, therefore, particularly sensitive to the economic conditions in these
markets. The local economic climate, which may be adversely impacted by business
layoffs or downsizing, industry slowdowns, changing demographics and other
factors, and local real estate conditions, such as oversupply of or reduced
demand for office, industrial and other competing commercial properties, may
affect our revenues and the value of our properties, including properties to be
acquired or developed. We cannot assure you that these local economies will
continue to grow at the current pace or at all.

Our acquisition of new properties and lack of operating history give rise to
difficulties in predicting revenue potential.

          From time to time, we acquire office properties. These acquisitions
could fail to perform in accordance with expectations. If we fail to accurately
estimate occupancy levels, operating costs or costs of improvements to bring an
acquired property up to the standards established for its intended market
position, the operating performance of the property may be below our
expectations. Acquired properties may have characteristics or deficiencies
affecting their valuation or revenue potential that we have not yet discovered.
We cannot assure you that the operating performance of acquired properties will
increase or be maintained under our management.

          During 2001, we acquired a total of seven properties containing 1.3
million net rentable square feet including two properties totaling 452,000 net
rentable square feet in which we acquired a 25% non-controlling interest. Our
ability to manage our growth effectively will require us to integrate
successfully our new acquisitions into our existing management structure. Some
of our properties have relatively short or no operating history under our
management. We have had limited control over the operation of these buildings.

Our redevelopment, development and construction activities may give rise to
unexpected costs and can make it difficult to predict revenue potential.

          We redevelop, develop and construct primarily office buildings. The
risks associated with these activities include:

     .    abandonment of redevelopment or development opportunities resulting in
          a loss of invested capital;

     .    construction costs of a property exceeding original estimates
          potentially resulting in yields on invested capital lower than
          expected;

     .    occupancy rates and rents at a newly renovated or completed property
          may not be sufficient to make the property profitable;

     .    financing may not be available on favorable terms for redevelopment or
          development of a property possibly increasing the projected cost of
          the project;

                                       35

<PAGE>

     .    permanent financing may not be available on favorable terms to replace
          short-term construction loans and construction and lease-up may not be
          completed on schedule, resulting in increased interest expense and
          construction costs;

     .    all necessary zoning, land-use, building, occupancy and other required
          governmental permits and authorizations may not be obtained or may not
          be obtained on a timely basis resulting in possible delays, decreased
          profitability and increased management time and attention; and

     .    increased management time required for such activities may divert
          their attention from other aspects of our business.

     These risks and potential costs may adversely affect our results of
operations.

Cost increases or revenue decreases can adversely affect property yields and
values.

          The yields available from equity investments in real estate depend in
large part on the amount of income generated and expenses incurred. If our
properties do not generate revenues sufficient to meet operating expenses,
including debt service, tenant improvements, leasing commissions and other
capital expenditures, we may have to borrow additional amounts to cover fixed
costs, and our cash flow and ability to make distributions to our shareholders
will be adversely affected.

     Factors which may affect our revenues and the value of our properties
include:

     .    the national, state and local economic climate and real estate
          conditions, such as oversupply of or reduced demand for space and
          changes in market rental rates;

     .    the perceptions of prospective tenants of the safety, convenience and
          attractiveness of our properties;

     .    our ability to provide adequate management, maintenance and insurance,
          including coverages for earthquakes and terrorist acts;

     .    our ability to collect on a timely basis all rent from tenants;

     .    the expense of periodically renovating, repairing and reletting
          spaces;

     .    increasing operating costs, including real estate taxes and utilities,
          which may or may not be passed through to tenants; and

     .    our compliance with the laws, changes in the tax laws, fluctuations in
          interest rates and the availability of financing.

     Certain significant expenditures associated with our properties, such as
mortgage payments, real estate taxes, insurance and maintenance costs, are
generally not reduced when circumstances cause a reduction in rental revenues
from our properties.

Tenant defaults and bankruptcy could cause rent collection difficulties.

          The risk that some of our tenants may declare bankruptcy is higher
because of the recent decline in the economy. A significant portion of our
income is derived from rental income on our properties. As of December 31, 2001,
we had approximately 1,100 tenants, with the following 7 tenants representing
approximately 17% of our aggregate annualized based rent and approximately 15%
of our total net rentable square footage leased: International Business
Machines, Kaiser Foundation Health Plan, Verizon Communications, MCI WorldCom,
Northrop Grumman Corporation, Aspen Systems Corporation and Moore North America.
We derived approximately 39% of our total annualized based rental revenue from
tenants in the computer systems design, broadcasting, telecommunications,
management, scientific, technical and insurance industries. As a result, our

                                       36

<PAGE>

distributable cash flow and ability to make expected distributions to our
shareholders could be adversely affected if any of these industries is
materially adversely affected by the economy or if a significant number of our
tenants fail to pay their rent due to bankruptcy, weakened financial condition
or otherwise. Our leases generally do not contain restrictions designed to
ensure the creditworthiness of our tenants. From time to time a tenant may
experience a downturn in its business. Such a downturn may weaken its financial
condition, and it may stop paying rent when due. In addition, at any time, a
tenant may seek the protection of the bankruptcy laws, which could result in
delays in rental payments or in the rejection and termination of such tenant
leases. These events would cause a reduction in our cash flow and the amounts
available for distributions to our shareholders. We cannot assure you that
tenants will not file for bankruptcy protection in the future or, if any tenants
file, that they will affirm their leases and continue to make rental payments in
a timely manner.

Property maintenance costs may escalate beyond our ability to recover such costs
through rents.

          Our properties are subject to increases in operating expenses, such as
cleaning; electricity; heating, ventilation and air conditioning; elevator
repair and maintenance; insurance and administrative costs; and other general
costs associated with security, landscaping, and repairs and maintenance. Due to
the terrorist acts of September 11, 2001, we expect security costs and insurance
premiums to increase. While our tenants generally are obligated to pay a portion
of these escalating costs, there can be no assurance that our tenants will agree
to pay such costs upon renewal or that new tenants will agree to pay such costs.
If operating expenses increase, the local rental market may limit the extent to
which rents may be increased to meet increased expenses without decreasing
occupancy rates. Our ability to make distributions to our shareholders could be
adversely affected if operating expenses increase without a corresponding
increase in revenues.

Non-renewal of leases and non-reletting of space could adversely affect our
rental revenues.

          We are subject to several risks upon expiration of leases for space
located at our properties. The leases may not be renewed, the space may not be
relet or the terms of renewal or reletting, including the costs of required
renovations, may be less favorable than current lease terms. Leases on a total
of approximately 6.3% of the total net rentable square feet in our properties
will expire during 2002. If we are unable to relet promptly or renew the leases
for a particular property or properties, if the rental rates upon such renewal
or reletting are significantly lower than expected rates or if our budgets for
these purposes prove to be inadequate, then our cash flow and ability to make
expected distributions to our shareholders may be adversely affected.

Some of our competitors in markets in which we have properties may have newer,
better-located or better-capitalized properties.

          Numerous office and industrial properties compete with our properties
in attracting tenants to lease space. In each market we compete on a number of
factors including rental rates, tenant concession allowances, quality and
location of buildings, quality of property management and other economic and
non-economic factors. Our major competitors in each market include the following
companies:

This competition could have an adverse effect on our operating performance
because some of these competing properties may be newer, better-located or
better-capitalized than our properties.

Properties with environmental problems could cause us to incur clean-up costs or
other liabilities.

          Various federal, state and local environmental laws, ordinances, and
regulations impose liability upon a current or previous owner or operator of
real property for the costs of removal or remediation of contamination caused by
hazardous or toxic substances or other wastes at the property. These laws often
impose liability whether or not the owner or operator knew of, or was
responsible for, the presence of the hazardous or toxic substances or other
waste. In addition, the presence of property contamination, or the failure to
remediate contamination at a property properly, may adversely affect a party's
ability to borrow using the real property as collateral. Persons who generate or
arrange for the disposal or treatment of hazardous or toxic substances or other
wastes may also be liable for the costs of removal or remediation of
contamination at a disposal or treatment facility, whether or not such facility
is or ever was owned or operated by them. Environmental laws and common law
principles also impose liability upon a party for the release of and exposure to
environmental contamination, including asbestos-containing materials into the
air, and third parties may use these laws to seek recovery from owners or
operators of property for personal injury or property damage associated with
environmental contamination, including asbestos-containing materials.

          As the owner of the properties, we may be liable for these types of
costs. We obtain environmental site assessments on all of our properties prior
to their acquisition. The purpose of environmental site assessments is to
identify potential recognized environmental conditions that may be associated
with a property. For a number of our properties, the environmental site
assessments also referenced prior Phase II environmental site assessments which
involved subsurface sampling and analysis on such properties.

          The previously-mentioned environmental site assessments have not
revealed any potential recognized environmental conditions that we believe could
have a material adverse effect on our business, assets or results of operations.
However, it is possible that the previously-mentioned environmental site
assessments relating to any one of our properties do not reveal all adverse
environmental conditions. In addition, there could be environmental conditions
that were created at a property after the applicable environmental site
assessment was completed.

          Effective January 1, 1999, we purchased insurance to cover
environmental conditions and business interruption if and when they occur. This
policy covers both governmental and third-party claims associated with the
covered environmental conditions. Our limits for loss under the policy are $5.0
million per occurrence and $5.0 million in the aggregate. We cannot assure you
that these coverages will be sufficient to cover all costs of environmental
issues that could arise.

Americans with Disabilities Act compliance could lead to unanticipated costs.

          The Americans with Disabilities Act of 1990 requires specified public
accommodations to meet federal requirements governing accessibility for persons
with disabilities related to access and use by disabled persons. Compliance with
the Americans with Disabilities Act could require modifications to our
properties. Non-compliance could result in, among other things, various
penalties including injunctive relief and monetary damages. Although we have no
basis for believing that our properties are not in compliance with the
requirements of the Americans with Disabilities Act, if we were required to make
unanticipated expenditures to comply with the Americans with Disabilities Act,
our cash flow and the amounts available for distributions to our shareholders
may be adversely affected.

Some of our properties may be subject to uninsured losses such as from
earthquakes or acts of terrorism.

          We carry comprehensive liability, fire, flood and, where appropriate,
extended coverage and rental loss insurance with respect to our properties, with
policy specifications and insured limits customarily carried for similar

                                       38

<PAGE>

properties. There are, however, certain types of losses, such as from wars, that
may be either uninsurable or the cost of obtaining insurance would be so high
that it would be more prudent to accept the risk of loss. We currently maintain
a $100 million blanket earthquake policy on the properties we own in Northern
and Southern California. Should an uninsured loss or a loss in excess of insured
limits occur, we could lose both capital invested in a property as well as the
anticipated future revenue from the property but would continue to be obligated
on any mortgage indebtedness or other obligations related to the property. Any
such loss would adversely affect our business, financial condition and results
of operations.

          Our real property insurance policies put into effect before September
11, 2001 do not expressly exclude coverage from hostile acts, except for acts of
war. Following the terrorist acts of September 11, 2001, however, insurance
policies purchased by us may expressly exclude hostile acts, and it may be
impossible to obtain insurance covering terrorist attacks. We may not be able to
purchase policies in the future with coverage limits and deductibles similar to
those that were available before September 11, 2001. In addition, we expect our
insurance premiums to increase in the future, which may have an adverse impact
on our cash flow.

Property ownership through partnerships and joint ventures could subject us to
the contrary business objectives of our partners or co-venturers.

          Through Prentiss Properties Acquisition Partners, L.P., our operating
partnership, we own non-controlling interests, including: (1) a non-controlling
50% interest in the Broadmoor Austin Associates; (2) a 20% non-controlling
interest in the Burnett Plaza; and (3) 25% non-controlling interest in Tysons
International Partners, which in the aggregate represented approximately $3.2
million in net income, or 3.1% of total net income, for the year ended December
31, 2001. Our pro-rata share of mortgage debt related to these unconsolidated
interests is approximately $99.9 million, or 12.3% of our total mortgage debt
outstanding, as of December 31, 2001. Through these interests, we act as
managing venture partner and have the authority to conduct business affairs of
each joint venture, subject to approval and veto rights of the other venture
partner.

          We may also participate with other entities in property ownership or
in providing property-related services through joint ventures or partnerships.
Partnership or joint venture investments may involve risks such as the
following:

     .    our partners or co-venturers might become bankrupt;

     .    our partners or co-venturers might at any time have economic or other
          business interests or goals that are inconsistent with our business
          interests or goals; and

     .    our partners or co-venturers may be in a position to take action
          contrary to our instructions or make requests contrary to our policies
          or objectives.

     We will, however, seek to maintain sufficient control of such partnerships
or joint ventures to achieve our business objectives. Although our
organizational documents do not limit the amount of available funds that we may
invest in partnerships or joint ventures, our senior credit facility requires
lender consent for certain investments in land, development projects and joint
ventures.

     In the future, we may acquire limited partnership interests in property
partnerships without partnership management responsibility or co-venturer
interests or co-general partnership interests in property partnerships with
shared responsibility for managing the affairs of the property partnership or
joint venture. In these instances, we will not be in a position to exercise sole
decision-making authority regarding the property partnership or joint venture.

Our properties are illiquid assets.

          Our investments in properties are relatively illiquid. This
illiquidity will tend to limit our ability to vary our portfolio promptly in
response to changes in economic or other conditions. Some of our properties are
mortgaged to secure payment of indebtedness. If we were unable to meet our
mortgage payments, the lender could foreclose on

                                       39

<PAGE>

the properties and we could incur a loss. In addition, if we wished to dispose
of one or more of the mortgaged properties, we might not be able to obtain a
release of the lien on the mortgaged property. If a lender forecloses on a
mortgaged property or if a mortgage lien prevents us from selling a property,
our funds available for distribution to our security holders could decline.

Our incurrence of debt could have a material adverse effect on operating
performance.

          If principal payments due at maturity cannot be refinanced, extended
or paid with proceeds of other capital transactions, such as the issuance of new
equity capital, we expect that our cash flow will not be sufficient in all years
to pay distributions at expected levels and to repay all maturing debt.
Furthermore, if prevailing interest rates or other factors at the time of
refinancing result in higher interest rates upon refinancing, the interest
expense relating to such refinanced indebtedness would increase. This increase
would adversely affect our cash flow and the amounts available for distributions
to our shareholders. If a property is mortgaged to collateralize payment of
indebtedness and we are unable to meet mortgage payments, the property could be
foreclosed upon by or otherwise transferred to the mortgagee with a consequent
loss of income and asset value.

Our use of variable rate debt and derivative financial instruments may cause an
increase in debt service.

          We have incurred and may incur in the future indebtedness that bears
interest at variable rates. Variable rate debt creates higher debt service
requirements if market interest rates increase, which would adversely affect our
cash flow and the amounts available for distributions to our shareholders.

          As of December 31, 2001, we had $265.8 million of floating rate debt
out of total debt, including our pro rata share of joint venture debt, of
$1,007.7 million. We enter into financial futures contracts and option contracts
in the ordinary course of our business to hedge or modify our exposures to
interest rate fluctuations. Of the floating rate debt, $250 million was swapped
to fixed rate debt through various interest rate protection contracts with
maturity dates ranging from January 2002 to March 2006. While our use of these
derivatives is intended to allow us to better manage certain risks, it is
possible that, over time, mis-matches may arise with respect to the derivatives
and the cash market instruments they are intended to hedge. Discrepancies can
also arise between the derivative and cash markets. Derivatives also have risks
that are similar in type to the risks of the cash market instrument on which
their values are based. For example, in times of market stress, sharp price
movements or reductions in liquidity in the cash markets may be related to
comparable or even greater price movements and reductions in liquidity in the
derivative markets. Further, the risks associated with derivatives are
potentially greater than those associated with the related cash market
instruments because of the additional complexity and potential for leverage. In
addition, derivatives may create credit risks, as well as legal, operational and
other risks beyond those associated with the underlying cash market instruments
on which their values are based. Credit risk involves the risk that a
counterparty on a derivative transaction will not fulfill its contractual
obligations. In an effort to limit credit risk, we have a policy that requires
the counterparty to the transaction to have a credit rating no lower that A- by
a nationally recognized rating agency at the time we enter into a derivative
transaction. There can be no assurance, however, that our hedging strategy or
techniques and policies for minimizing credit and other risks associated with
our hedging activity will be effective, that our profitability will not be
adversely affected during any period of changes in interest rates or that the
costs of hedging will not exceed the benefits.

If we are unable to replace construction loans with permanent refinancing, we
may have to sell the development properties at a loss.

          If new developments are financed through construction loans or if
acquisitions are financed with short-term bridge loans in anticipation of later,
permanent financing, there is a risk that upon completion of construction or the
maturity of the bridge loans, permanent financing may not be available or may be
available only on disadvantageous terms. As of December 31, 2001, we were not a
party to any construction loan commitments. In the event that we enter into such
financing arrangements and upon maturity are unable to obtain permanent
financing for these properties on favorable terms, we could be forced to sell
such properties at a loss or the properties could be foreclosed upon by the
lender and result in loss of income and asset value.

                                       40

We depend on our direct and indirect subsidiaries' dividends and distributions,
and these subsidiaries' creditors and preferred security holders are entitled to
payment of amounts payable to them by the subsidiaries before the subsidiaries
may pay any dividends or distributions to us.

          Substantially all of our assets consist of our partnership interests
in Prentiss Properties Acquisition Partners, our operating partnership. Our
operating partnership holds substantially all of its properties and assets
through subsidiaries. Our operating partnership, therefore, depends for
substantially all of its revenue on cash distributions to it by its
subsidiaries. The creditors of each subsidiary are entitled to payment of the
subsidiary's obligations to them, when due and payable, before distributions may
be made by the subsidiary to our operating partnership. Thus, our operating
partnership's ability to make distributions to its unit holders depends on its
subsidiaries' ability to satisfy their obligations to their creditors and make
distributions to our operating partnership. In addition, the right of our
operating partnership unit holders to participate in any distribution of the
assets of any of our operating partnership's direct or indirect subsidiaries
upon the liquidation, reorganization or insolvency of the subsidiary, and any
consequent right of our operating partnership unit holders to participate in
those assets, will be subject to the claims of the creditors and preferred
security holders, if any, of the subsidiary. Furthermore, the holders of
preferred units of our operating partnership are entitled to receive preferred
distributions before payment of distributions to holders of operating
partnership common units, including us. Thus, our ability to pay dividends to
holders of our common shares depends on our operating partnership's ability
first to satisfy its obligations to its creditors and make distributions payable
to holders of preferred units and then to make distributions to us. Subsequent
to the repurchase of our Series C preferred Units in January 2002, there are two
series of preferred units of our operating partnership not held by us which have
preference over our common shares, the Series B Preferred Units and Series E
Preferred Units. The Series B Preferred Units have a total liquidation value of
approximately $95 million, and the Series E Preferred Units have a total
liquidation value of approximately $10 million. In addition, our shareholders
will have the right to participate in any distribution of the assets of any of
our direct or indirect subsidiaries upon the liquidation, reorganization or
insolvency of the subsidiary, and consequently to participate in those assets,
only after the claims of the creditors, including trade creditors, and preferred
security holders, if any, of the subsidiary are satisfied.

Risks Related to Our Company

Our shareholders' ability to effect a change of control may be limited.

We have a shareholder rights plan.

          In February 1998, we adopted a shareholder rights plan and declared a
dividend of one purchase right for each common share of beneficial interest. The
purchase rights may have the effect of delaying, inhibiting or preventing a
transaction or a change in control of us that might involve a premium price for
the common shares or otherwise be in the best interest of our shareholders. The
purchase rights can cause substantial dilution to a person or group that
acquires 10% or more of our outstanding common shares unless the purchase rights
have been redeemed by our board of trustees. However, because the purchase
rights are redeemable by our board of trustees, the purchase rights should not
interfere with any merger or other business combination approved by our board of
trustees.

We have an ownership limitation.

          In order to maintain our qualification as a REIT under the Internal
Revenue Code of 1986, as amended, no more than 50% in value of our outstanding
shares of beneficial interest may be owned, directly or indirectly, by five or
fewer individuals during the last half of our taxable year, other than our 1996
taxable year. To ensure that we will not fail to qualify as a REIT, our
declaration of trust authorizes our board of trustees to take such actions as
are necessary and desirable to preserve our qualification as a REIT. In
addition, our declaration of trust has an ownership limitation which provides
that no person may own, directly or indirectly, more than 8.5% of the number of
outstanding common shares, other than Michael V. Prentiss, who currently may own
up to 15% of the number of outstanding common shares, or more than 9.8% of the
number of outstanding preferred shares of beneficial interest of any series. The
board of trustees, upon receipt of a ruling from the IRS, an opinion of counsel
or other evidence satisfactory to our board of trustees, may exempt a proposed
transferee from the ownership limitation. For example, our board of trustees has
exempted Security Capital Preferred Growth Incorporated from the ownership
limitation on

                                       41

<PAGE>

the condition that Security Capital Preferred Growth Incorporated not own more
than 11% of the number of outstanding common shares. The board of trustees may
not grant an exemption from the ownership limitation to any proposed transferee
if such exemption would result in the termination of our status as a REIT. The
ownership limitation may have the effect of delaying, inhibiting or preventing a
transaction or a change in control that might involve a premium price for the
common shares or otherwise be in the best interests of our shareholders.

We have a staggered board.

          Our board of trustees is divided into three classes, each with a three
year term, thus, only a portion of our board of trustees stand for election at
each annual meeting. The staggered terms of trustees may reduce the possibility
of a tender offer or an attempt to change control of us, even though a tender
offer or change in control might be in the best interest of our shareholders.

The board of trustees can issue additional shares.

     Our declaration of trust authorizes our board of trustees to:

     .    amend our declaration of trust, without shareholder approval, to
          increase or decrease the aggregate number of shares of beneficial
          interest or the number of shares of beneficial interest of any class
          that we have the authority to issue;

     .    issue additional authorized but unissued preferred or common shares;
          and

     .    classify or reclassify any unissued common shares or preferred shares
          and to set the preferences, rights and other terms of such classified
          or unclassified shares.

     These provisions may have the effect of delaying, deferring or preventing a
transaction or a change in control that might involve a premium price for the
common shares or otherwise be in the best interest of our shareholders.

Our status as a REIT is dependent on compliance with federal income tax
requirements.

          We have operated and intend to continue to operate as a REIT for
federal income tax purposes. We have not requested, and do not expect to
request, a ruling from the IRS (1) that the operating partnership and each of
its non-corporate subsidiaries have been and will be classified as partnerships
for federal income tax purposes or (2) that we qualify as a REIT. Qualification
as a REIT involves the application of highly technical and complex provisions of
the Internal Revenue Code, with limited judicial and administrative guidance
available, to facts and circumstances that may be subject to differing
interpretations for federal income tax purposes.

          While we have operated and intend to continue to operate as a REIT for
federal income tax purposes, if the IRS were to successfully challenge the tax
status of the operating partnership or a non-corporate subsidiary as a
partnership, or if we fail to qualify as a REIT for any taxable year, we would
be subject to federal income tax at regular corporate rates. Unless entitled to
relief under the Internal Revenue Code, we also would be disqualified from
treatment as a REIT for the four taxable years following the disqualification
year. As a result, cash available for distribution would be reduced for each of
the years involved.

          Although we intend to continue to operate as a REIT, future economic,
market, legal, tax or other considerations may cause our board of trustees, with
the consent of our shareholders holding at least a majority of all the
outstanding common shares, to revoke the REIT election.

We have minimum distribution requirements that could require us to incur
additional debt.

          To qualify as a REIT prior to 2001, we were required to distribute at
least 95% of our net taxable income to our shareholders, excluding any net
capital gain. As a result of the REIT Modernization Act, the distribution
requirement was reduced to 90% for 2001 and future years. In addition, to avoid
a 4% non-deductible excise tax, we must also distribute annually at least the
sum of the following:

                                       42

<PAGE>

     .    85% of our ordinary income for that year,

     .    95% of our capital gain net income for that year, and

     .    100% of our undistributed taxable income from prior years.

     We have exceeded the distribution requirements in every year and we expect
to comply with the distribution requirements. If unfavorable market conditions
exist, we may have to borrow funds on a short-term basis to meet the REIT
distribution requirements. If such unfavorable conditions occurred, we might not
be able to fund all future capital needs with income from operations, and might
have to rely on third-party sources of capital, which may or may not be
available on favorable terms.

Changes in tax laws could affect our REIT status.

          At any time, future legislation or administrative or judicial
decisions or actions could affect our tax treatment or qualification as a REIT,
possibly with retroactive effect. While we do not anticipate any such decisions
or actions, the rules dealing with federal income taxation are constantly under
review by persons involved in the legislative process and by the IRS and the
U.S. Treasury Department. We cannot predict whether, when, in what forms, or
with what effective dates, the tax laws applicable to us or an investment in us
might be changed.

Conflicts of interests in our business could result in decisions not in your
best interest.

Prentiss principals could have differing objectives from other shareholders upon
the sale, refinancing or prepayment of indebtedness of properties.

          Messrs. Prentiss and August, our senior executive officers, and their
affiliates may have unrealized taxable gain associated with their units of
limited partnership interest in the operating partnership. Messrs. Prentiss and
August may suffer different and more adverse tax consequences than our other
shareholders upon the sale or refinancing of properties that were contributed to
the operating partnership by Messrs. Prentiss and August. Therefore, Messrs.
Prentiss and August and our other shareholders may have different objectives
regarding the appropriate pricing and timing of any sale or refinancing of
properties. While we, through Prentiss Properties I, Inc., the general partner
of the operating partnership, have the exclusive authority as to whether and on
what terms to sell or refinance an individual property, Messrs. Prentiss and
August may influence us not to sell, or refinance or prepay the indebtedness
associated with properties even though such a transaction might otherwise be to
our financial advantage, or may influence us to refinance properties with a high
level of debt.

Our policies with respect to conflicts of interests may not eliminate the
influence of conflicts.

          We have adopted policies intended to minimize conflicts of interest.
For example, our bylaws provide that all transactions in which executive
officers or trustees have a conflicting interest with us may be subject to
approval by a majority of our trustees that are not affiliated with any of our
affiliates or by the holders of a majority of the common shares held by
disinterested shareholders. We have implemented a code of business conduct
governing the conduct of all employees which further reduces the potential for
conflicts of interest. There can be no assurance that our policies will be
successful in eliminating the influence of conflicts. Decisions could be made
that might fail to reflect fully the interests of all our shareholders. Our
declaration of trust includes a provision permitting each individual trustee to
engage in the type of business activities conducted by us without first
presenting any investment opportunities to us, even though such investment
opportunities may be within the scope of our investment policies.

Our board of trustees may change policies and incur debt without shareholder
approval.

          Our board of trustees determines our investment, financing, borrowing
and distribution policies, and our policies with respect to all other
activities, including growth, capitalization and operations. Our board of
trustees has adopted a policy limiting our total combined indebtedness plus our
pro rata share of joint venture debt to 50% or less of our total market
capitalization, but our organizational documents do not contain any limitation
on the amount of indebtedness we may incur. Although our board of trustees has
no present intention to do so, these policies may

                                       43

<PAGE>

be amended or revised at any time and from time to time at the discretion of our
board of trustees, limited only by various restrictions in our credit agreement,
without a vote of our shareholders. Our credit agreements limit total
indebtedness to 55% of total assets and require a debt service coverage ratio of
at least 2 to 1. A change in our investment, financing, borrowing and
distribution policies could adversely affect our financial condition, results of
operations or the market price of our common shares.

We are dependent on the services of Michael V. Prentiss and Thomas F. August.

          We are dependent on the efforts of our chairman and chief executive
officer, Messrs. Prentiss and August. The loss of their services could have an
adverse effect on our operations. Each of Messrs. Prentiss and August has
entered into an employment agreement which will expire in February 2006 and May
2003, respectively. Messrs. Prentiss and August have agreed in their employment
agreements that for a period of two years after they are no longer employed by
us they will not enter into employment with any company which is in a business
that is competitive to our business. If this provision, or if similar provisions
in other employment agreements with our other employees, is determined to not be
binding on Messrs. Prentiss or August, or any other employee, those persons
would be able to enter into employment with companies which compete with us
immediately after those persons ceased to be employed by us.

Our third-party property management, leasing, development and construction
business and related services involve relationships which may be subject to
early termination or a lack of control.

          Through our operating partnership and Prentiss Properties Resources,
the manager, we engage in the business of management, leasing, development and
construction of properties owned by third parties. Risks associated with these
activities include the following:

     .    related contracts, which are typically cancelable upon 30-days notice
          or upon specific events, including sale of the property, may be
          terminated by the property owner or may be lost in connection with a
          sale of such property;

     .    contracts may not be renewed upon expiration or may not be renewed on
          terms consistent with current terms; and

     .    rental revenues upon which management, leasing and development fees
          are based may decline as a result of general real estate market
          conditions or specific market factors affecting properties that we
          manage, lease or develop, resulting in decreased management, leasing
          or development fee income.

     The capital stock of the manager is divided into two classes: voting common
stock, all of which is owned by Mr. Prentiss; and non-voting common stock, all
of which we hold through the operating partnership. The voting common stock
represents 2% of the ownership interests in the manager and the non-voting
common stock represents 98% of the ownership interests in the manager. Mr.
Prentiss, as the holder of all of the manager's voting common stock, has the
ability to elect the directors of the manager. We are not able to elect
directors and, therefore, are not able to influence the day-to-day management
decisions of the manager. As a result, the board of directors and management of
the manager may implement business policies or decisions that we would not have
implemented and that are adverse to our interests and which could adversely
impact our net operating income and cash flow.

We have shares available for future sale that could adversely affect the price
of our common shares.

Under our declaration of trust, our board of trustees has the authority to do
the following:

     .    amend our declaration of trust, without shareholder approval, to

     As of December 31, 2001, we have authorized 100,000,000 common shares, of
which 62,984,113 common shares are unissued. In addition, we have granted
options to purchase 3,686,566 common shares to executives officers, employees
and trustees, of which options to purchase 2,179,175 common shares remain
outstanding. We have reserved a total of 3,773,585 common shares for issuance
upon conversion of the Series D Preferred Shares. Sales or issuances of a
substantial number of common shares, or the perception that such sales could
occur could adversely affect prevailing market prices of the common shares and
dilute the percentage ownership held by our shareholders.

     Limited partners of our operating partnership have the right to receive, in
our or the general partner's discretion, either cash or one common share, in
exchange for each limited partnership unit they now hold, if and to the extent
they tender such units for redemption. As of December 31, 2001, there were
1,522,036 common units of our operating partnership outstanding and held by
partners other than Prentiss Properties Trust, and, if we or the general partner
elect to redeem such units for common shares, these common units are
exchangeable for 1,522,036 common shares. We are party to registration rights
agreements under which we are required to register the issuance of common shares
which we may issue upon the redemption by the holders of units of limited
partnership interest in our operating partnership. We can make no prediction
concerning the effect that such issuance or future sales of any such common
shares will have on market prices.

Changes in market conditions could hurt the market price of our shares.

          The value of our common shares depends on various market conditions,
which may change from time to time. Among the market conditions that may affect
the value of our common shares are the extent of institutional investor interest
in us; the reputation of REITs generally and the attractiveness of their equity
securities in comparison to other equity securities, including securities issued
by other real estate companies, and fixed income securities; our financial
condition and performance; and general financial market conditions. In addition,
the stock market in recent years has experienced extreme price and volume
fluctuations that have often been unrelated or disproportionate to the operating
performance of companies.

Increased market rates may hurt the value of our shares.

We believe that investors consider the distribution rate on REIT shares,
expressed as a percentage of the price of the shares, relative to market
interest rates as an important factor in deciding whether to buy or sell the
shares. If market interest rates go up, prospective purchasers of REIT shares
may expect a higher distribution rate. Higher interest rates would not, however,
result in more funds for us to distribute and in fact, would likely increase our
borrowing costs and might decrease our funds available for distribution. Thus,
higher market interest rates could cause the market price of our common shares
to decline.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

     Our primary market risk exposure is to changes in interest rates as a
result of our revolving credit facility and long-term debt. At December 31,
2001, we had outstanding total indebtedness, including our pro rata share of
joint venture debt, of approximately $1.01 billion, or approximately 43.4% of
total market capitalization based on a common share price of $27.45 per common
share. Our interest rate risk objective is to limit the impact of interest rate
fluctuations on earnings and cash flows and to lower our overall borrowing
costs. To achieve this objective, we manage our exposure to fluctuations in
market interest rates for our borrowings through the use of fixed rate debt
instruments to the extent that reasonably favorable rates are obtainable with
such arrangement. In addition, we may enter into derivative financial
instruments such as options, forwards, interest rate swaps, caps and floors to
mitigate our interest rate risk on a related financial instrument or to
effectively lock the interest rate on a portion of our variable rate debt. We do
not enter into derivative or interest rate transactions for speculative
purposes. Approximately 73.6% of our outstanding debt was subject to fixed rates
with a weighted average interest rate of 7.45% at December 31, 2001. Of the
remaining $265.8 million, or 26.4%, representing our variable rate debt, $250.0
million was effectively locked at an interest rate before the spread over LIBOR,
of 5.50% through our interest rate swap agreements. We regularly review interest
rate exposure on our outstanding borrowings in an effort to minimize the risk of
interest rate fluctuations.

     The following table provides information about our financial instruments
that are sensitive to changes in interest rates, including interest rate swaps
and debt obligations. For debt obligations outstanding at December 31, 2001, the
table presents principal cash flows and related weighted average interest rates
for the debt outstanding during the periods. The debt outstanding as presented
in the table includes our pro rata share of joint venture debt. For interest
rate swaps, the table presents notional amounts and weighted average interest
rates for in-place swaps during the period. Notional amounts are used to
calculate the contractual payments to be exchanged under the contract. Weighted
average variable rates are based on 30-day LIBOR as of December 31, 2001. The
fair value of our fixed rate debt indicates the estimated principal amount of
debt having similar debt service requirements, which could have been borrowed by
us at December 31, 2001. The rate assumed in the fair value calculation of fixed
rate debt is equal to 7.09%, which consists of the 7-year treasury of 4.84% at
December 31, 2001 plus 225 basis points. The fair value of our variable to fixed
interest rate swaps indicates the estimated amount that would have been paid by
us had they been terminated at December 31, 2001.

     The table incorporates only those exposures that exist as of December 31,
2001 and does not consider exposures or positions which could arise after that
date. In addition, because firm commitments are not represented in the table
above, the information presented therein has limited predictive value. As a
result, our ultimate realized gain or loss with respect to interest rate
fluctuations will depend on the exposures that arise during future periods,
prevailing interest rates, and our hedging strategies at that time. There is
inherent rollover risk for borrowings as they mature and are renewed at current
market rates. The extent of this risk is not quantifiable or predictable because
of the variability of future interest rates and our financing requirements.

                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Trustees and Shareholders
Of Prentiss Properties Trust:

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income, shareholders' equity, comprehensive income
and cash flows present fairly, in all material respects, the financial position
of Prentiss Properties Trust (the "Company") at December 31, 2001 and 2000, and
the results of its operations and its cash flows for each of the three years in
the period ended December 31, 2001 in conformity with accounting principles
generally accepted in the United States of America. These financial statements
are the responsibility of the Company's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with auditing standards
generally accepted in the United States of America, which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note (2) to the consolidated financial statements, effective
January 1, 2001, the Company adopted the provisions of Statement of Financial
Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities."

                              FINANCIAL STATEMENTS

(1)  The Organization and Significant Transactions

     We are a self-administered and self-managed Maryland REIT that acquires,
owns, manages, leases, develops and builds primarily office properties
throughout the United States. We are self-administered in that we provide our
own administrative services, such as accounting, tax and legal, internally
through our own employees. We are self-managed in that we internally provide all
the management and maintenance services that our properties require through
employees, such as, property managers, leasing professionals and engineers. We
operate principally through our operating partnership, Prentiss Properties
Acquisition Partners, L.P. and its subsidiaries, and a management company,
Prentiss Properties Resources, Inc. and its subsidiaries. As of December 31,
2001, we owned interests in a diversified portfolio of 146 primarily suburban
Class A office and suburban industrial properties containing approximately 17.6
million net rentable square feet. Our properties consist of 108 office
properties containing approximately 14.4 million net rentable square feet and 38
industrial properties containing approximately 3.2 million net rentable square
feet. The properties include 3 development properties containing 445,000 square
feet of office space that are in various stages of development. As of December
31, 2001, our properties, exclusive of the development properties, were 94%
leased to approximately 1,100 tenants. In addition to managing the properties
that we own, we manage approximately 19.7 million net rentable square feet in
office, industrial and other properties for third parties.

Real Estate Transactions

     During the year, we completed several real estate transactions with
Brandywine Realty Trust. In April 2001, we completed an asset exchange whereby
we conveyed our interests in 30 properties and approximately 6.9 acres of
developable land located in Pennsylvania, New Jersey and Delaware with a
carrying amount of $207.5 million in exchange for four wholly-owned office
properties in Northern Virginia valued at $107.2 million.

     In addition to the asset exchange, we issued to Brandywine 200,000, $50 par
value, preferred units and 26,768 common units, collectively valued at $10.7
million, as consideration for a 25% non-controlling interest in a joint venture
that owns two office properties containing 452,000 net rentable square feet in
the Northern Virginia area.

     In June 2001, we completed our transactions with Brandywine with the sale
of a 103,000 net rentable square foot development project in the suburban
Philadelphia area. As a result of these transactions, we disposed of all of our
holdings in the suburban Philadelphia market and closed our Northeast regional
office.

     Inclusive of the transactions described above, during the year ended
December 31, 2001, we (1) disposed of 42 properties containing 2.8 million net
rentable square feet, resulting in a gain on sale of $13.9 million; (2) acquired
seven properties containing 1.3 million net rentable square feet for an
aggregate purchase price of $134.9 million; (3) demolished one property which
contained 29,000 net rentable square feet, the land parcel under which will be
held for future development; and (4) transitioned four office properties
containing 592,000 net rentable square feet from development into operations.

(2)  Summary of Significant Accounting Policies

Principles of Consolidation

     We consolidate all subsidiaries that we control and we define control as
the ownership of a majority of the voting interest of a subsidiary. Our
consolidated financial statements include the accounts of Prentiss Properties
Trust, Prentiss Properties Acquisition Partners, L.P. and other subsidiaries
under our control. All significant inter-company balances and transactions have
been eliminated. Certain prior year amounts have been reclassified to conform to
current year presentation with no impact on previously reported net income or
shareholders' equity.

Real Estate

     Real estate and leasehold improvements are classified as long-lived assets
held for sale or long-lived assets to be held and used. In accordance with
Statement of Financial Accounting Standards No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," we
record assets held for sale at the lower of the carrying amount or fair value
less cost to sell. With respect to assets classified as held and used, we
periodically review these assets to determine whether our carrying amount will
be recovered from the undiscounted

                                      F-8

                            PRENTISS PROPERTIES TRUST
                              NOTES TO CONSOLIDATED
                              FINANCIAL STATEMENTS

future operating cash flows and we recognize an impairment loss to the extent
the carrying amount is not recoverable and exceeds its fair value. No such
impairment losses on assets held for use have been recognized to date.

     Depreciation on buildings and improvements is provided under the
straight-line method over an estimated useful life of 30 to 40 years for office
buildings and 25 to 30 years for industrial buildings. Interest expense and
other directly related expenses incurred during construction periods are
capitalized and depreciated commencing with the date the building is placed in
service, on the same basis as the related asset. For the years ended December
31, 2001, 2000 and 1999, capitalized interest costs totaled $5.2 million, $3.4
million and $5.2 million, respectively.

     Expenditures for repairs and maintenance are charged to operations as
incurred. Significant betterments are capitalized. When assets are sold or
retired, their costs and related accumulated depreciation are removed from the
accounts with the resulting gains or losses reflected in net income for the
period.

Deferred Charges

     Leasing commissions and leasehold improvements are deferred and amortized
on a straight-line basis over the terms of the related lease. Deferred financing
costs are recorded at cost and are amortized using the effective interest method
over the life of the related debt. Other deferred charges are amortized over
terms applicable to the expenditure.

Cash and Cash Equivalents

     Cash and cash equivalents consist of cash on hand and investments with
maturities of three months or less from the date of purchase.

Escrowed Cash

     Escrowed cash includes real estate tax, insurance and capital reserve
deposits required pursuant to certain of our mortgage loan agreements.

Investments in Securities

     Investments in securities consist of investments in marketable securities
held pursuant to a key employee share option plan. We account for our
investments in securities as "available for sale" in accordance with Statement
of Financial Accounting Standards No. 115 "Accounting for Certain Investments in
Debt and Equity Securities." Any decline in market value that is deemed to be
other than temporary is recognized as a realized loss in the determination of
net income for the period. No such realized loss has been recognized to date.
Any change in the market value of the investments which is deemed temporary is
included as an unrealized gain or loss in accumulated other comprehensive income
on our consolidated balance sheet. At December 31, 2001, we have an accumulated
unrealized gain of $366,000 from our investments in securities. The unrealized
gain is presented in accumulated other comprehensive income on our consolidated
balance sheet.

Investments in Joint Ventures and Unconsolidated Subsidiaries

     As of December 31, 2001, we have investments in joint ventures and
unconsolidated subsidiaries which we account for using the equity method of
accounting including (i) our 50% interest in Broadmoor Austin Associates; (ii)
our 20% interest in Burnett Plaza Associates; (iii) our 25% interest in Tysons
International Partners, (iv) our 98% interest in Prentiss Properties Resources,
Inc.; and (v) our 75% interest in PPS Partners LLC.

     We have a non-controlling interest in these investments and account for our
interest using the equity method of accounting, thus, we report our share of
income and losses based on our ownership interest in the respective entities. We
classify our interest in subsidiaries as non-controlling when we hold less than
a majority of the entities' outstanding voting stock. Any difference between the
carrying amount of our non-controlling interests and the book value of the
underlying equity is amortized over 40 years from the date of purchase. For each
of the years ended December 31, 2001, 2000 and 1999, the amortization totaled
approximately $254,000.

     In January 2002, we will implement Statement of Financial Accounting
Standards No. 142, "Goodwill and Other Intangible Assets." Upon initial
application of this statement, the portion of the excess of cost over the

                                      F-9

                              FINANCIAL STATEMENTS

underlying equity in net assets of an investee accounted for using the equity
method that had been recognized as goodwill shall cease being amortized.

Income Taxes

     We have elected to be taxed as a REIT under Sections 856 through 860 of the
Internal Revenue Code of 1986, as amended. If we qualify for taxation as a REIT,
we generally will not be subject to federal corporate income tax on our taxable
income that is distributed to our shareholders. A REIT is subject to a number of
organizational and operational requirements, including a requirement that it
currently distribute at least 90% of its annual taxable income.

Leases

     We, as lessor, have retained substantially all the risks and benefits of
ownership and account for our leases as operating leases.

Revenue Recognition

     In accordance with Statement of Financial Accounting Standards No. 13
"Accounting for Leases," income on leases which includes scheduled rental rate
increases over the lease term is recognized on a straight-line basis. Income
received from tenants for early lease terminations is recognized as earned.

     Management fees, leasing and other fee income items received are recognized
as earned. Leasing fees are generally recognized upon tenant occupancy of the
leased premises unless such fees are irrevocably due and payable upon lease
execution, in which case recognition occurs on the lease execution date.

Distributions

     We pay regular quarterly distributions to the holders of our outstanding
common shares. These distributions are dependent on distributions from our
operating partnership. The holders of our Series D Convertible Preferred Shares
receive a quarterly dividend per share equal to the per share distribution paid
on our common shares.

     Earnings and profits, which will determine the taxability of distributions
to shareholders, will differ from income reported for financial reporting
purposes due to the differences for federal tax purposes, primarily in the
estimated useful lives used to compute depreciation.

Minority Interest

     Minority interest in the operating partnership represents the limited
partners' proportionate share of the equity in the operating partnership. The
operating partnership pays a regular quarterly distribution to the holders of
common and preferred units. Income is allocated to minority interest based on
the weighted average percentage ownership during the year.

     Minority interest in real estate partnerships represents the other
partners' proportionate share of the equity in certain real estate partnerships.
The operating partnership holds a majority controlling interest in the real
estate partnerships and thus, consolidates the accounts into the operating
partnership. Income is allocated to minority interest based on the weighted
average percentage ownership during the year.

Concentration of Credit Risk

     We place cash deposits at major banks. We believe that through our cash
investment policy, the credit risk related to these deposits is minimal.

Use of Estimates in the Preparation of Financial Statements

     The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires us to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported

                                      F-10

                            PRENTISS PROPERTIES TRUST
                              NOTES TO CONSOLIDATED
                              FINANCIAL STATEMENTS

amounts of revenues and expenses during the reporting period. These estimates
include such items as depreciation, allowance for doubtful accounts and
accruable rental income. Actual results could differ from our estimates.

Fair Value of Financial Instruments

     Statement of Financial Accounting Standards No. 107, "Disclosures about
Fair Value of Financial Instruments" requires disclosures about the fair value
of financial instruments whether or not such instruments are recognizable in the
balance sheet. Our financial instruments include receivables, cash and cash
equivalents, escrowed cash, investments in securities, accounts payable, other
accrued expenses, mortgages and notes payable and interest rate hedge
agreements. The fair values of these financial instruments, other than the fixed
rate mortgages and notes payable, are not materially different from their
carrying or contract amounts. We estimate the fair value of our consolidated
fixed rate mortgages and notes payable to exceed the carrying amount by $12.8
million at December 31, 2001.

Fair Value of Derivative Instruments

     On January 1, 2001, we adopted Statement of Financial Accounting Standards
No. 133, "Accounting for Derivative Instruments and Hedging Activities," as
amended by Statement of Financial Accounting Standards No. 138, "Accounting for
Certain Derivative Instruments and Certain Hedging Activities." The statement as
amended, establishes accounting and reporting standards for derivative
instruments. Specifically it requires an entity to recognize all derivatives as
either assets or liabilities in the statement of financial position and to
measure those instruments at fair value. Changes in fair value will affect
either shareholders' equity or net income depending on whether the derivative
instrument qualifies as a hedge for accounting purposes.

     The adoption, on January 1, 2001, of Statement of Financial Accounting
Standards No. 133, as amended, resulted in a charge of $2.5 million to other
comprehensive income in the first quarter of 2001. In addition to the initial
charge, during 2001, we recorded the reduction in fair value of our derivatives
of $8.0 million as a loss of $469,000 recognized in our statement of income as
interest expense and a charge of $7.5 million to other comprehensive income.

     On December 31, 2001, our derivative financial instruments were reported at
their fair value as a liability of $10.5 million. Of the liability, $10.0
million represents an unrealized loss and is presented in accumulated other
comprehensive income in our consolidated statement of changes in shareholders'
equity.

     Accruable rental income represents rental income recognized on a

individual lease agreements.

     Effective June 30, 1999, we loaned $4.2 million to various key employees as
part of our long-term incentive plan to retain such employees. The funds were
used to purchase common shares of the company in the open market. The loans are
full recourse notes, which accrue interest quarterly at a fixed rate of 7% and
have a term of five years. Interest payments are due quarterly. The loan
balances are to be forgiven, contingent upon each key employees' continued
employment with us, in the following manner: one-third of the principal balance
will be forgiven at the end of the third year of the loan term, one-third will
be forgiven at the end of the fourth year of the loan term, and the remaining
principal balance will be forgiven at the end of the fifth year of the loan
term. The outstanding loan balance totaled $2.4 million and $2.9 million at
December 31, 2001 and 2000, respectively and is reflected in the other

/(1)/We own a 50% non-controlling interest in Broadmoor Austin Associates, an
     entity, which owns a seven-building, 1.1 million net rentable square foot

(7)  Mortgages and Notes Payable

     In March 2001, we repaid the $100.0 million outstanding balance under an
unsecured term loan with Dresdner Bank. The loan had an interest rate of LIBOR

repaid with proceeds from our revolving credit facility and a $75.0 million
unsecured term loan completed with Commerzbank.

     On May 10, 2001, we completed a $45.0 million, 12-year non-recourse,

Assurance Society of the United States. The loan bears interest at a fixed rate
of 7.41% and is collateralized by three office properties comprising 277,000 net
rentable square feet in the San Diego area. The proceeds from the loan were used
to re-pay (1) the $25.3 million of outstanding borrowings under the construction
loan which was collateralized by the Del Mar Gateway property and (2) a portion
of outstanding borrowings under our revolving credit facility.

     On September 28, 2001, we completed a $45.0 million, 10-year non-recourse,

     Under our loan agreements, we are required to satisfy various affirmative
and negative covenants, including limitations on total indebtedness, total
collateralized indebtedness and cash distributions, as well as obligations to
maintain certain minimum tangible net worth and certain minimum interest
coverage ratios. We were in compliance with these covenants at December 31,
2001.

(8)  Interest Rate Hedges

     In the normal course of business, we are exposed to the effect of interest
rate changes. We limit these risks by following established risk management
policies and procedures including the use of derivatives. For interest rate
exposures, derivatives are used primarily to hedge against rate movements on our
related debt.

                              NOTES TO CONSOLIDATED
                              FINANCIAL STATEMENTS

     To manage interest rate risk, we may employ options, forwards, interest
rate swaps, caps and floors or a combination thereof depending on the underlying
exposure. We undertake a variety of borrowings from credit facilities, to
medium- and long-term financings. To hedge against increases in interest cost,
we use interest rate instruments, typically interest rate swaps, to convert a
portion of our variable rate debt to fixed rate debt.

     On the date we enter into a derivative contract, we designate the
derivative as a hedge of (a) a forecasted transaction or (b) the variability of
cash flows that are to be received or paid in connection with a recognized asset
or liability (cash flow hedge). Currently, we have only entered into derivative
contracts designated as cash flow hedges. These agreements involve the exchange
of amounts based on a variable interest rate for amounts based on fixed interest
rates over the life of the agreement based upon a notional amount. The
difference to be paid or received as the interest rates change is recognized as
an adjustment to interest expense. The related amount payable to or receivable
from counterparties is included in accounts payable and other liabilities.
Changes in the fair value of a derivative that is highly effective and that is
designated and qualifies as a cash flow hedge, to the extent that the hedge is
effective, are recorded in other comprehensive income, until earnings are
affected by the variability of cash flows of the hedged transaction (e.g. until
periodic settlements of a variable-rate asset or liability are recorded in
earnings). Any hedge ineffectiveness (which represents the amount by which the
changes in the fair value of the derivative exceed the variability in the cash
flows of the forecasted transaction) is recorded in current-period earnings.
Changes in the fair value of non-hedging instruments are reported in
current-period earnings.

     We formally document all relationships between hedging instruments and
hedged items, as well as our risk-management objective and strategy for
undertaking various hedge transactions. This process includes linking all
derivatives that are designated as cash flow hedges to (1) specific assets and
liabilities on the balance sheet or (2) specific firm commitments or forecasted
transactions. We also formally assess (both at the hedge's inception and on an
ongoing basis) whether the derivatives that are used in hedging transactions
have been highly effective in offsetting changes in the cash flows of hedged
items and whether those derivatives may be expected to remain highly effective
in future periods. When it is determined that a derivative is not (or has ceased
to be) highly effective as a hedge, we discontinue hedge accounting
prospectively, as discussed below.

     We discontinue hedge accounting prospectively when (1) we determine that
the derivative is no longer effective in offsetting changes in the cash flows of
a hedged item (including hedged items such as firm commitments or forecasted
transactions); (2) the derivative expires or is sold, terminated, or exercised;
(3) it is no longer probable that the forecasted transaction will occur; (4) a
hedged firm commitment no longer meets the definition of a firm commitment; or
(5) management determines that designating the derivative as a hedging
instrument is no longer appropriate.

     When we discontinue hedge accounting because it is no longer probable that
the forecasted transaction will occur in the originally expected period, the
gain or loss on the derivative remains in accumulated other comprehensive income
and is reclassified into earnings when the forecasted transaction affects
earnings. However, if it is probable that a forecasted transaction will not
occur by the end of the originally specified time period or within an additional
two-month period of time thereafter, the gains and losses that were accumulated
in other comprehensive income will be recognized immediately in earnings. In all
situations in which hedge accounting is discontinued and the derivative remains
outstanding, we will carry the derivative at its fair value on the balance
sheet, recognizing changes in the fair value in current-period earnings.

     To determine the fair value of derivative instruments, we use a variety of
methods and assumptions that are based on market conditions and risks existing
at each balance sheet date. For our derivatives, standard market conventions and
techniques such as discounted cash flow analysis, option pricing models,
replacement cost, and termination cost are used to determine fair value. All
methods of assessing fair value result in a general approximation of value, and
such value may never actually be realized.

     Over time, the unrealized gains and losses held in accumulated other
comprehensive income will be reclassified to earnings. This reclassification is
consistent with when the hedged items are recognized in earnings. Within the
next twelve months, we expect to reclassify to earnings approximately $3.7
million of the current balance held in accumulated other comprehensive income.

(12) Supplemental Disclosure of Non-Cash Investing and Financing Activities

     On December 28, 2001, we declared cash distributions totaling $22.6 million
payable to holders of common shares, operating partnership units and Series D
Convertible Preferred Shares. The distributions were paid January 11, 2002. In
addition, distributions totaling $3.2 million and $187,500 were declared on
December 28, 2001, payable to holders of our Series B and C Perpetual Preferred
Units and Series E Preferred Units, respectively. The distributions were paid on
January 3, 2002 and January 16, 2002 to our Series B and C Perpetual Preferred
Unit holders and Series E Preferred Unit holders, respectively.

     Pursuant to our long-term incentive plan, during the year ended December
31, 2001, we issued 89,700 restricted shares of stock to various key employees.
The shares which had a market value of $2.2 million based upon the per share
price on the date of grant were classified as either (1) compensation for past
performance or (2) unearned future compensation. An amount totaling $784,000
represents compensation for past performance and was recognized in earnings
during the year ended December 31, 2000. An amount equal to $1.4 million
represents unearned future compensation and was recorded as unearned
compensation in the shareholders' equity section the consolidated balance sheet.
The unearned compensation is amortized quarterly as compensation expense over
the three-year vesting period.

     During 2001, 182,214 operating partnership units were converted to common
shares. The fair value of the units, which were converted at various points in
time throughout the period, totaled $5.0 million based upon the closing price of
our common shares on the date of the respective conversion. In connection with
the Brandywine transaction, we issued common and preferred operating partnership
units with a value of $10.7 million in exchange for a non-controlling 25%
interest in Tysons International Partners.

     During 2001, we removed accumulated depreciation and amortization of $19.4
million and $5.6 million, related to real estate and deferred charges disposed
of during the period. In addition, as a result of our disposition of certain
real estate properties, we removed receivables of $1.2 million, escrowed cash of
$486,000, other assets of $735,000, liabilities of $2.3 million and mortgages
and notes payable of $91.7 million. In addition, we moved from real estate to
investments in joint ventures and unconsolidated subsidiaries, $1.1 million
representing our non-controlling retained interest in certain properties
disposed of during the period. In relation to the properties acquired during the
period, we assumed liabilities totaling approximately $708,000.

     In March 2001, we contributed (1) our interest in Prentiss Properties
Limited, Inc.; (2) 4.2 acres of developable land with a carrying value of $1.1
million; and (3) our investment in Narrowcast Communications Corporation with a
carrying value of $423,000 in exchange for class B non-voting common stock of
Prentiss Properties Resources, Inc.

     During 2001, common shares in treasury increased by $25.6 million of which
$15.6 million represented non-cash activities including (1) $15.3 million
attributable to 563,494 common shares surrendered as payment of the exercise
price and statutory tax withholdings for certain share options exercised during
the period and (2) $252,000 representing 12,244 restricted share grants
forfeited as a result of certain employee terminations during the period.

(13) Related Party Transactions

     On March 28, 2001, Prentiss Properties Resources, Inc. was incorporated
under the General Corporation Law of the State of Delaware to serve as a Taxable
REIT Subsidiary and provide management services to the operating partnership. On
March 29, 2001, Prentiss Properties Resources, Inc. acquired our interest in the
existing management service company, Prentiss Properties Limited, Inc., valued
at $3.9 million, along with certain other assets with a carrying amount of
approximately $2.5 million. As a result, the operating partnership holds a 98%
economic interest and 0% voting interest in Prentiss Properties Resources, Inc.
We account for our non-controlling interest in the management service company
and its subsidiaries using the equity method of accounting.

     The management service company and its subsidiaries incur certain personnel
and other overhead-related expenses on behalf of the operating partnership,
which are subsequently reimbursed. Such expenses totaled $4.0 million and $3.7
million for the years ended December 31, 2001 and December 31, 2000,
respectively. In addition, the operating partnership funds short-term capital
needs of the management service company, which are subsequently reimbursed. We
had outstanding short-term borrowings due to the management service company of
$4.4 million at December 31, 2001 and $3.6 million at December 31, 2000. The
short-term borrowings were classified as other payables (affiliates) in our
consolidated balance sheets at December 31, 2001 and December 31, 2000.

(14) Employee Benefit Plans

     We have a 401(k) savings plan for our employees. Under the plan, as
amended, employees, age 21 and older, are eligible to participate in the plan
after they have completed one year and 1,000 hours of service. Participants are
immediately vested in their contributions, matching contributions and earnings
thereon.

     We initially match 25% of an employees' contribution, not to exceed 25% of
6% of each employee's wages. Our cost of the initial match totaled approximately
$333,000 and $325,000 for the years ended December 31, 2001 and 2000,
respectively. We may also elect, in any calendar year, to make a discretionary
match to the plan. The amount paid pursuant to the discretionary match totaled
$300,000 and $0 during the years ended December 31, 2001 and 2000, respectively.

     We have registered 500,000 common shares in connection with a share
purchase plan. The share purchase plan enables eligible employees to purchase
shares, subject to certain restrictions, of the company at a 15% discount to
fair market value. A total of 65,340 and 45,864 common shares were issued, in
accordance with the share purchase plan, during the years ended December 31,
2001 and 2000, respectively.

     We have adopted a deferred compensation plan. Pursuant to the plan,
officers and other selected key employees of the operating partnership or
management service company who earn bonuses have the option of deferring the
payment of such bonuses. Such deferred compensation may be used to purchase
various mutual funds and/or our

common shares. Pursuant to the participant's election, we purchase shares on the
open market and place them in a trust for the benefit of such participant. The
trust may deliver to the participant shares or the fair market value of such
shares beginning 6 months from the date they were placed in the trust. The
purpose of the deferred compensation plan is to provide a vehicle for the
payment of compensation otherwise payable to the participants, in a form that
will provide incentives and rewards for meritorious performance and encourage
the recipients' continuance as our employees. During the 2000 and 2001 plan
years we provided a discount of 15% on the purchase price of our common shares
purchased by participants in the plan. For the 2002 plan year, the deferred
compensation plan will not provide for a discount on our common shares. The
investments (including 97,600 of our common share purchased in the open market)
are carried at their market value of $3.4 million and included in investments in
securities. The corresponding deferred compensation liability of approximately
$3.4 million is included in accounts payable and other liabilities.

(15) Share Incentive Plans

     We have two separate stock-based incentive compensation plans including (1)
a trustees' share incentive plan and (2) an employees' share incentive plan. We
apply APB Opinion 25 and related Interpretations in accounting for each plan. In
1995, the Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 123 "Accounting for Stock-Based Compensation" which, if
fully adopted, would change the methods we use in recognizing the cost of our
plans. Adoption of the cost recognition provisions of the statement is optional
and we have decided not to elect these provisions. However, pro forma
disclosures as if we had adopted the cost recognition provisions are required
and are presented herein.

     Under the plans, we are authorized to issue common shares or cash pursuant
to awards granted in the form of (1) non-qualified stock options not intended to
qualify under Section 422 of the Internal Revenue Code of 1986, as amended; (2)
restricted or non-restricted shares; (3) stock appreciation rights; and (4)
performance shares. Awards may be granted to selected employees and trustees of
our company or an affiliate of our company.

The Trustees' Plan

     Under the trustees' plan, annually on the first business day of July we
grant to each independent trustee non-qualified stock options to purchase 7,500
of our common shares. The options are 100% vested at grant. In 2001, we issued
to the independent trustees, a total of 37,500 non-qualified stock options.

     On the first business day of each fiscal quarter, we issue to each
independent trustee common shares having an aggregate value of $6,250, based on
the per share value of the common shares on the date of grant. The common shares
are 100% vested at grant and, therefore, expensed upon issuance. A total of
4,750 and 5,100 common shares were granted pursuant to the plan for the years
ended December 31, 2001 and 2000, respectively.

The Employees' Plan

     Under the employees' plan, we are authorized to issue awards with respect
to a maximum of 5,000,000 common shares. Awards may be granted to employees of
the operating partnership or management service company. No participant may be
granted, in any calendar year, awards in the form of stock options or stock
appreciation rights with respect to more than 390,000 common shares or
restricted share awards for more than 50,000 common shares. We have broad
discretion in determining the vesting terms and other terms applicable to awards
granted under the plan.

     The exercise price of each option granted during 2001 was equal to the per
share fair market value of our common shares on the date of grant. Under the
employees' plan, during 2001, we granted 459,000 options which vest 33-1/3% per
year on each anniversary of the date of grant, commencing with the first
anniversary of the date of grant. In addition, we issued 89,700 restricted
shares which vest 100% on the third anniversary of the date of grant.

     A summary of the status of our options as of December 31, 2001, December
31, 2000 and December 31, 1999 and the changes during the year ended on those
dates is presented below:

(16) Capital Shares

     Our board of trustees is authorized to provide for the issuance of
100,000,000 common shares and 20,000,000 preferred shares in one or more series,
to establish the number of shares in each series and to fix the designation,
powers, preferences and rights of each such series and the qualifications,
limitations or restrictions thereof. As of December 31, 2001, 37,015,887 and
3,773,585 common shares and Series D Convertible Preferred Shares were issued
and outstanding, respectively. The Series D Convertible Preferred Shares are
convertible at the holder's option on a one-for-one basis into our common
shares, subject to certain adjustments, and may not be redeemed by us before
December 29, 2004. In addition to the 37,015,887 common units outstanding which
were held by Prentiss Properties Trust at December 31, 2001, the operating
partnership had 1,522,036 common units outstanding, all of which are redeemable
at the option of the holder for a like number of common shares, or at our
option, the cash equivalent thereof.

     In June 1998, we privately placed 1,900,000 8.30% Series B Cumulative
Redeemable Perpetual Preferred Units of our operating partnership with Belair
Capital Fund. In connection with the private placement, on June 25, 1998, we
designated 1,900,000 Series B Preferred Shares. We may redeem the Series B
Preferred Units at any time after June 25, 2003 for cash in an amount equal to
the capital account balance subject to certain limitations. The holders of the
Series B Preferred Units may exchange the Series B Preferred Units at any time
on or after June 25, 2008 for Series B Preferred Shares at an exchange rate of
one Series B Preferred Share for one Series B Preferred Unit, subject to
adjustments. As of December 31, 2001, no Series B Preferred Shares were issued
or outstanding.

     In September 1999, we privately placed 2,000,000 9.45% Series C Cumulative
Redeemable Perpetual Preferred Units of our operating partnership with Belair
Real Estate Corporation and Belcrest Realty Corporation. In connection with the
private placement, on September 17, 1999, we designated 2,000,000 Series C
Preferred Shares. We may redeem the Series C Preferred Units at any time after
September 17, 2004 for cash in an amount equal to the capital account balance
subject to certain limitations. The holders of the Series C Preferred Units may
exchange the Series C Preferred Units at any time on or after September 17, 2009
for Series C Preferred Shares at an exchange rate of one Series C Preferred
Share for one Series C Preferred Unit, subject to adjustments. As of December
31, 2001, no Series C Preferred Shares were issued or outstanding. See Note (23)
- "Subsequent Events," regarding the repurchase of all of our outstanding Series
C Cumulative Redeemable Perpetual Preferred Units.

     In April 2001, we completed an asset exchange with Brandywine Realty Trust.
As part of that exchange, we acquired Brandywine's Northern Virginia assets
which includes a 25% non-controlling interest in the Tysons International
Partners joint venture that owns two office properties. In exchange for the
joint venture interest, we issued to Brandywine a combination of 200,000 7.50%
Series E Cumulative Preferred Units of our operating partnership and 26,768
common units of our operating partnership. The holders of the Series E Preferred
Units may choose to have the Series E Preferred Units redeemed at any time on or
after April 10, 2004. The Series E Preferred Units are redeemable for either
$10.0 million plus accrued but unpaid distributions or, at our option, common
shares having a market value equal to the redemption price. In addition, each
common unit held by Brandywine is exchangeable after April 10, 2003, for either
cash equal to the trading price of one common share at the time of the exchange
or, at our option, one common share.

     The Series B and C Perpetual Preferred Units and Series E Preferred Units
are accounted for at their redemption value in the line item minority interest
in operating partnership on our consolidated balance sheet.

     During 1998, our board of trustees authorized the repurchase of up to 2.0
million common shares in the open market or negotiated private transactions.
Through December 31, 1999, we purchased 1.5 million common shares at an average
purchase price of $22.70 per share. On January 4, 2000, the board of trustees
authorized a 1.5 million-share increase in the share repurchase program bringing
the total authorization to 3.5 million common shares. Immediately following such
authorization, we repurchased 1.5 million shares from an institutional owner at
$19.00 per share. On May 9, 2001, the board of trustees authorized an additional
1.0 million-share increase in the share repurchase program bringing the total
authorization to 4.5 million shares. During the year ended December 31, 2001,
pursuant to the share repurchase program, we purchased, in the open market,
410,900 shares at an average purchase price of $24.32 per share. At December 31,
2001, we have the ability to purchase an additional 1.1 million shares under the
share repurchase program.

(17) Earnings per Share

     We calculate earnings per share in accordance with Statement of Financial
Accounting Standards No. 128, "Earnings per Share" which requires a dual
presentation of basic and diluted earnings per share on the face of the income
statement. Additionally, the statement requires a reconciliation of the
numerator and denominator used in computing basic and diluted earnings per
share. The table below presents a reconciliation of the numerator and

/(1)/Preferred shares for the year ended December 31, 2000 are excluded from
     the denominator in calculating dilutive earnings per share as such shares
     were anti-dilutive for the period; therefore, the numerator used in the
     calculation of dilutive earnings per share is income available to common
     shareholders for the year ended December 31, 2000 as compared to the year
     ended December 31, 2001, for which the numerator is net income.

environmental condition, liability or compliance concern that we believe may
have a material adverse effect on our business, assets or results or operations,
nor are we aware of any such condition, liability or concern. It is possible

/(1)/Net rentable square feet defines the area of a property for which a tenant
     is required to pay rent, which includes the actual rentable area plus a
     portion of the common area of the property allocated to the tenant.
/(2)/As of December 31, 2001, we have incurred $64.4 million of the total
     estimated cost of our development properties.
/(3)/We classify our construction projects as development properties until the
     projects are substantially complete and ready for their intended use.
     Typically, this includes shell completion and improvements made to the net
     rentable area within the building.

Insurance

     We have and will keep in force comprehensive insurance, including
liability, fire, workers' compensation, extended coverage, rental loss and, when
available on reasonable commercial terms, flood and earthquake insurance, with
policy specifications, limits and deductibles customarily carried for similar
properties. We currently maintain insurance to cover environmental conditions
and business interruption if and when they occur. This policy covers both
governmental and third-party claims associated with the covered environmental
conditions. Our real property insurance policies exclude earthquake coverage for
properties located within California. As a result, we maintain a $100 million
blanket earthquake policy on the properties we own in Northern and Southern
California. Certain types of losses, however, generally of a catastrophic
nature, such as acts of war, are either uninsurable or the cost of obtaining
insurance is so high that it is more prudent to accept the risk of loss. Our
real property insurance policies put into effect before September 11, 2001 do
not expressly exclude coverage from hostile acts, except for acts of war.
Following the terrorist acts of September 11, 2001, however, insurance policies
purchased by us may expressly exclude hostile acts, and it may be impossible to
obtain insurance covering terrorist attacks. We may not be able to purchase
policies in the future with coverage limits and deductibles similar to those
that were available before September 11, 2001. In addition, we expect our
insurance premiums to increase in the future, which may have an adverse impact
on our cash flow. We believe that our properties are adequately insured in
accordance with industry standards.

(19) Recently Issued Accounting Standards

     In August 2001, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets." The statement which is effective for financial
statements issued for fiscal years beginning after December 15, 2001 and interim
periods within those fiscal years, addresses financial accounting and reporting
for the impairment or disposal of long-lived assets. The impact from the
implementation of this statement, which we believe will not have a material
impact on our financial statements, will be dependent upon (1) which if any of
our assets qualify as held for sale at January 1, 2002 or at any point in time
thereafter; (2) whether the carrying amount of such assets determined to be held
for sale is greater than the fair value less cost of sale of the assets; and (3)
whether the carrying amount of assets determined not to be held for sale is
recoverable from the undiscounted future cash flow from operations and from the
eventual sale of the assets.

(20) Segment Information

     Our primary business is the ownership and operation of office and
industrial properties throughout the United States. We have determined that our
reportable segments are those that are based on our method of internal
reporting, which disaggregates our business by geographic region. Our
transactions with Brandywine Realty Trust, which were completed during 2001,
included the sale of all of our properties in our Northeast Region and as a
result, at December 31, 2001, we no longer have operations in the Northeast
Region. In addition, during December 2001, we changed our internal reporting
dividing our West Region into separate Northern and Southern California Regions.
As of December 31, 2001, our reportable segments include our five regions (1)
Mid-Atlantic; (2) Midwest; (3) Southwest; (4) Northern California; and (5)
Southern California. For comparative purposes, the results of operations, of
prior years, attributable to our West Region have been reclassified into
separate Northern and Southern California Regions.

     The table below presents information about net income and segment assets
used by our chief operating decision maker as of and for the years ended
December 31, 2001, 2000, and 1999, respectively:

(22) Income Taxes

     We have elected to be taxed as a REIT under sections 856 through 860 of the
Internal Revenue Code of 1986, commencing with our taxable year ended December
31, 1996. To qualify as a REIT, we must meet a number of organizational and
operational requirements, including a requirement that we currently distribute
at least 90% of our adjusted taxable income to our shareholders. It is our
current intention to adhere to these requirements and maintain our REIT status.
As a REIT, we generally will not be subject to corporate level federal income
tax on taxable income we distribute currently to our shareholders. If we fail to
qualify as a REIT in any taxable year, we will be subject to federal income
taxes at regular corporate rates (including any applicable alternative minimum
tax) and may not be able to qualify as a REIT for four subsequent taxable years.
Even if we qualify for taxation as a REIT, we may be

(23) Subsequent Events

     Using proceeds from our revolving credit facility, in January 2002, we
contributed $3.0 million to a joint venture established to develop two
multi-story office buildings in Del Mar, California. Our contribution represents
a 70% controlling interest in the joint venture. Also using proceeds from our
revolving credit facility, we made a loan totaling $6.6 million to the joint
venture. The loan, which matures in January 2005, bears interest at 10% per
annum for the first twelve months of the loan term and 12% thereafter. The loan
requires interest only payments until maturity.

     On January 31, 2002, using proceeds from our revolving credit facility, we
acquired from Teachers Insurance and Annuity Association of America, the $47.0
million mortgage loan on the Burnett Plaza property. The loan was originally
scheduled to mature February 1, 2002. The loan bears interest at 7.50% through
March 2002 and 10% through its maturity on December 31, 2002. At December 31,
2001, the Burnett Plaza property, a 1.0 million net rentable square foot office
building in Downtown Fort Worth was owned pursuant to a joint venture agreement
between us and an affiliate of Lend Lease Real Estate Investments as 20% and 80%
owners, respectively. On March 7, 2002, we purchased from Burnett Plaza - VEF
III, L.P., an affiliate of Lend Lease Real Estate Investments, its 80% interest
in the joint venture for a purchase price of approximately $51.2 million. The
Burnett transaction was funded with proceeds from our revolving credit facility
and in part by the consummation of the private placement of 613,750 common
shares of beneficial interest with Salomon Smith Barney Inc. The private
placement closed in February 2002 with net proceeds from the sale of the common
shares totaling approximately $16.5 million after underwriting discounts and
commissions and before offering expenses. Salomon Smith Barney Inc. was granted
registration rights and a thirty-day option to purchase up to an additional
92,063 common shares at $28.35 per common share.

     In January 2002, we entered into an interest rate swap agreement with a
notional amount of $50.0 million which fixed 30-day LIBOR at 2.2775%. The swap,
which matures in January 2003, effectively fixes the interest rate at 3.6525% on
$50.0 million of variable rate borrowings.

     Using proceeds from our revolving credit facility, on January 3, 2002, we
repurchased all of our outstanding units of 9.45% Series C Cumulative Redeemable
Perpetual Preferred Units of our operating partnership for approximately $50.6
million, including accrued and unpaid dividends.
