PS BUSINESS PARKS, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
September 30, 2002


1. Organization and description of business

PS Business Parks, Inc. ("PSB") was incorporated in the state of California
in 1990. As of September 30, 2002, PSB owned approximately 75% of the
common partnership units of PS Business Parks, L.P. (the "Operating
Partnership" or "OP"). The remaining common partnership units were owned by
Public Storage, Inc. ("PSI") and its affiliated entities. PSB, as the sole
general partner of the Operating Partnership, has full, exclusive and
complete responsibility and discretion in managing and controlling the
Operating Partnership. PSB and the Operating Partnership are collectively
referred to as the "Company."


The Company is a fully-integrated, self-advised and self-managed real
estate investment trust ("REIT") that acquires, develops, owns and operates
commercial properties containing commercial and industrial rental space. As
of September 30, 2002, the Company owned and operated approximately 14.8
million net rentable square feet of commercial space located in eight
states. The Company also managed approximately 1.7 million net rentable
square feet on behalf of PSI and its affiliated entities, third party
owners and a joint venture in which the Company held a 25% equity ownership
interest (See Note 2).

2. Summary of significant accounting policies

Basis of presentation

The accompanying unaudited condensed consolidated financial statements have
been prepared in accordance with accounting principles generally accepted
in the United States for interim financial information and with
instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly,
they do not include all of the information and footnotes required by
accounting principles generally accepted in the United States for complete
financial statements. The preparation of the condensed consolidated
financial statements in conformity with accounting principles generally
accepted in the United States requires management to make estimates and
assumptions that affect the amounts reported in the condensed consolidated
financial statements and accompanying notes. Actual results could differ
from estimates. In the opinion of management, all adjustments necessary for
a fair presentation have been included and are of a normal recurring
nature. Operating results for the three and nine months ended September 30,
2002 are not necessarily indicative of the results that may be expected for
the year ended December 31, 2002. For further information, refer to the
consolidated financial statements and footnotes thereto included in the
Company's Annual Report on Form 10-K for the year ended December 31, 2001.


The condensed consolidated financial statements include the accounts of PSB
and the Operating Partnership. All significant intercompany balances and
transactions have been eliminated in the condensed consolidated financial
statements.

Financial instruments

The methods and assumptions used to estimate the fair value of financial
instruments are described below. The Company has estimated the fair value
of financial instruments using available market information and appropriate
valuation methodologies. Considerable judgement is required in interpreting
market data to develop estimates of market value. Accordingly, estimated
fair values are not necessarily indicative of the amounts that could be
realized in current market exchanges.

7



In June 1998, the Financial Accounting Standards Board issued Statement No.
133 "Accounting for Derivative Instruments and Hedging Activities," (SFAS
133, as amended by SFAS 138). The Statement requires the Company to
recognize all derivatives on the balance sheet at fair value. Derivatives
that are not hedges must be adjusted to fair value and reflected as income
or expense. If the derivative is a hedge, depending on the nature of the
hedge, changes in the fair value of derivatives are either offset against
the change in fair value of the hedged assets, liabilities, or firm
commitments through earnings or recognized in other comprehensive income
until the hedged item is recognized in earnings. The ineffective portion of
a derivative's change in fair value is immediately recognized in earnings.

In July, 2002, the partnership entered into an interest rate swap
agreement, which is accounted for as a cash flow hedge, to reduce the
impact of changes in interest rates on a portion of its floating rate debt.
The agreement, which covers $50,000,000 of debt through July, 2004
effectively changes the interest rate exposure from floating rate to a
fixed rate of 4.46%. Market gains and losses on the value of the swap are
deferred and included in income over the life of the swap or related debt.
For the three and nine months ended September 30, 2002, the transaction was
determined to be an effective hedge. The Partnership records the
differences paid or received on the interest rate swap in interest expense
as payments are made or received.

Net interest differentials to be paid or received related to these
contracts were accrued as incurred or earned. Included in comprehensive
income is $974,000 in unrealized loss related to the interest rate swap as
of September 30, 2002. Upon termination of the contract, the related
balance in comprehensive income is recognized into income or expense in the
period the contract matures or is terminated.


The Company considers all highly liquid investments with an original
maturity of three months or less at the date of purchase to be cash
equivalents. Due to the short period to maturity of the Company's cash and
cash equivalents, accounts receivable, other assets and accrued and other
liabilities, the carrying values as presented on the condensed consolidated
balance sheets are reasonable estimates of fair value. Based on borrowing
rates currently available to the Company, the carrying amount of debt
approximates fair value.


Financial assets that are exposed to credit risk consist primarily of cash
and cash equivalents and receivables. Cash and cash equivalents, which
consist primarily of short-term investments, including commercial paper,
are only invested in entities with an investment grade rating. Receivables
are comprised of balances due from a large number of customers. Balances
that the Company expects to become uncollectable are reserved for or
written off.

Marketable securities

Marketable securities are classified as "available-for-sale" in accordance
with Statement of Financial Accounting Standards ("SFAS") No. 115,
Accounting for Certain Investments in Debt and Equity Securities.
Investments are reflected on the balance sheet at fair market value based
upon the quoted market price. Comprehensive income of approximately
$211,000 represents $1,185,000 in unrealized gains from investments in
marketable securities, offset by an unrealized loss of $974,000 from the
Company's interest rate swap contract. These items are excluded from
earnings and reported in a separate component of shareholders' equity.
Dividend income is recognized when earned.

8



Real estate facilities

Real estate facilities are recorded at cost. Costs related to the
renovation or improvement of the properties are capitalized. Expenditures
for repairs and maintenance are expensed as incurred unless the expenditure
is expected to benefit a period greater than 30 months and exceeds $5,000.
Buildings and equipment are depreciated on the straight-line method over
the estimated useful lives, which are generally 30 and 5 years,
respectively. Leasing costs in excess of $1,000 for leases with terms
greater than two years are capitalized and depreciated/amortized over their
estimated useful lives. Leasing costs for leases of less than two years or
less than $1,000 are expensed as incurred.

Interest cost and property taxes incurred during the period of construction
of real estate facilities are capitalized. The Company capitalized $288,000
and $1,001,000 of interest expense during the nine months ended September
30, 2002 and 2001, respectively. As of September 30, 2002, all developed
properties had been shell complete for at least one year and the Company
was no longer capitalizing interest expense on these facilities.

9



Investment in joint venture

In October 2001, the Company formed a joint venture with an unaffiliated
investor to own and operate an industrial park in the City of Industry
submarket of Los Angles County. The park, consisting of 294,000 square feet
of industrial space, was acquired by the Company in December 2000 at a cost
of approximately $14.4 million. The property was contributed to the joint
venture at its original cost. The partnership is capitalized with equity
capital consisting of 25% from the Company and 75% from the unaffiliated
investor in addition to a mortgage note payable.

In May 2002, the joint venture disposed of two buildings in the park
totaling 47,000 square feet for approximately $3 million ($2.8 million net
of closing costs). In September, 2002, the joint venture disposed of two
additional buildings totaling 28,700 square feet for approximately $2.2
million ($2.0 million net of closing costs). The Company recognized its 25%
share of the gain on the dispositions totaling $265,000 (approximately $1.0
million for the joint venture). As of September 30, 2002, the joint venture
holds 10 buildings totaling 218,000 square feet which the joint venture is
currently under contract to sell.


Summarized below is financial data for the joint venture as of September
30, 2002.

For the nine months

Real estate, net.................................... $ 10,725,000
Total assets........................................ 12,368,000

Notes payable....................................... 5,004,000
Total liabilities................................... 7,531,000
Partner's equity.................................... 4,841,000

The Company's investment at September 30, 2002...... $ 901,000

The joint venture has a variable rate mortgage obligation of approximately
$5 million, which currently bears interest at 5.45% per annum and is due on
November 1, 2005. Under certain conditions, the Company has guaranteed
repayment of the mortgage. The Company's investment is accounted for under
the equity method in accordance with APB 18, "Equity Method of Accounting
for Investments." In accordance with APB 18, the Company's share of the
debt is netted against its share of the assets in determining the
investment in the joint venture of $901,000 and is not included in the
Company's total liabilities.

10



Subsequent to September 30, 2002, the joint venture sold an additional two
buildings totaling 48,276 square feet for net proceeds of approximately
$1.9 million. The joint venture recognized a gain of approximately $577,000
and the Company's share was approximately $200,000. The remaining buildings
are under contract to be sold. The net proceeds are expected to be
approximately $7.5 million, resulting in an expected gain of approximately
$3.9 million. The Company's share of the gain would be approximately $1.2
million. In addition, the Company would recognize an incentive fee of
approximately $1.6 million. There can be no assurance that these sales will
be completed or the gains and incentive fees recognized.

Intangible assets

Intangible assets consist of property management contracts for properties
managed, but not owned, by the Company. The intangible assets are being
amortized over seven years. Intangible assets are net of accumulated
amortization of $1,703,000 and $1,477,000 at September 30, 2002 and
December 31, 2001, respectively.

Evaluation of asset impairment

The Company evaluates its assets used in operations, by identifying
indicators of impairment and by comparing the sum of the estimated
undiscounted future cash flows for each asset to the asset's carrying
amount. When indicators of impairment are present and the sum of the
undiscounted future cash flows is less than the carrying value of such
asset, an impairment loss is recorded equal to the difference between the
asset's current carrying value and its value based on discounting its
estimated future cash flows. In addition, the Company evaluates its assets
held for disposition. Assets held for disposition are reported at the lower
of their carrying amount or fair value, less cost of dispositions. At
September 30, 2002, the Company determined that the net proceeds from the
sale of one of its assets held for sale would be less than the carrying
value, resulting in a $900,000 impairment charge.

Loan from affiliate

The Company borrowed an aggregate of $35 million from PSI in 2001. The note
bore interest at 3.25% (per annum) and was repaid along with accrued
interest expense of $76,000 in January 2002. A portion of the proceeds from
the Series F preferred stock issuance described in Note 9 was used to repay
the note.

Insurance Coverage

The Company combines its insurance purchasing power with PSI through a
captive insurance company controlled by PSI, STOR-Re Mutual Insurance
Corporation (STOR-Re). STOR-Re provides limited property and liability
insurance to the Company at commercially competitive rates. The Company and
PSI also utilize unaffiliated insurance carriers to provide property and
liability insurance in excess of STOR-Re's limitations. During the period
ended September 30, 2002 and 2001, the Company paid approximately $900,000
and $675,000 in premiums to STOR-Re, respectively.

Revenue and expense recognition

All leases are classified as operating leases. Rental income is recognized
on a straight-line basis over the terms of the leases. Deferred rent
receivables represents rental revenue accrued on a straight-line basis in
excess of rental revenue currently billed. Reimbursements from tenants for
real estate taxes and other recoverable operating expenses are recognized
as revenues in the period the applicable costs are incurred.

11



Lease Termination Fees

Certain leases have termination options whereby the lessee may terminate
the lease prior to its expiration. In most circumstances, the lessee is
required to pay a fee to terminate the lease. In general, these fees are
calculated by adding two factors. 1) Unamortized leasing costs, including
tenant improvements and broker commissions and 2) an amount to cover the
cost of re-leasing the space. The Company accounts for these fees as
follows: 1) reducing the balance in unamortized leasing costs 2) a reserve
to cover estimated re-leasing costs and 3) the balance (if any) as revenue.
During the nine months ended September 30, 2002 and 2001, the Company
collected approximately $1.5 million and $0.3 million respectively in lease
termination fees, and recognized $0.3 million and $0.3 million respectively
as rental income. Approximately 5% of the Company's rental revenue is
subject to termination options with approximately 3% exercisable through
December 2003. In general, these leases provide for termination payments
should the termination option be exercised.

Property management fees are recognized in the period earned.

The Company disposed of a property in San Diego for approximately $9
million in November 2001 and deferred a gain of $5,366,000 which was later
recognized in 2002 when the buyer of the property obtained third party
financing for the property and paid off most of its note to the Company.
The note receivable balance remaining as of September 30, 2002 and December
31, 2001 was $200,000 and $7,450,000, respectively.

General and administrative expense

General and administrative expense includes executive compensation, office
expense, professional fees, state income taxes, cost of acquisition
personnel and other such administrative items.

Until December 31, 2001, we elected to adopt the disclosure requirements of
FAS 123 but continued to account for stock-based compensation under APB 25.
Effective January 1, 2002, we have adopted the Fair Value Method of
accounting for stock options. As required by the transition requirements of
FAS 123, we will recognize compensation expense in our income statement
using the Fair Value Method only with respect to stock options issued after
January 1, 2002, but continue to disclose the pro-forma impact of utilizing
the Fair Value Method on stock options issued prior to January 1, 2002. As
a result, included in the Company's income statement for the nine months
ended September 30, 2002 is approximately $343,000 in stock option
compensation expense related to options granted after January 1, 2002. With
respect to stock options granted prior to December 31, 2001, the Company
would have reported net income of approximately $43,415,000 and $36,661,000
for the nine months ended September 30, 2002 and 2001, respectively, and
reported diluted earnings per share of $1.46 and $1.35, respectively, had
we accounted for these options under FAS 123 for options granted prior to
December 31, 2001.

Income taxes

The Company believes it has qualified and intends to continue to qualify as
a REIT, as defined in Section 856 of the Internal Revenue Code. As a REIT,
the Company is not subject to federal income tax to the extent that it
distributes its taxable income to its shareholders. A REIT must distribute
at least 90% of its taxable income each year. In addition, REIT's are
subject to a number of organizational and operating requirements. If the
Company fails to qualify as a REIT in any taxable year, the Company will be
subject to federal income tax (including any applicable alternative minimum
tax) based on its taxable income using corporate income tax rates. Even if
the Company qualifies for taxation as a REIT, the Company may be subject to
certain state and local taxes on its income and property and to federal
income and excise taxes on its undistributed taxable income. The Company
believes it met all organizational and operating requirements to maintain

12



its REIT status during 2001 and intends to continue to meet such
requirements for 2002. Accordingly, no provision for income taxes has been
made in the accompanying financial statements.

Net income per common share

Per share amounts are computed using the number of weighted average common
shares outstanding. "Diluted" weighted average common shares outstanding
includes the dilutive effect of stock options under the treasury stock
method. "Basic" weighted average common shares outstanding excludes such
effect. Earnings per share have been calculated as follows:

3. Real estate facilities

The activity in real estate facilities for the nine months ended September
30, 2002 is as follows:



Accumulated
Land Buildings Depreciation Total
---------------- ---------------- ---------------- ----------------

Balances at December 31, 2001...... $ 287,182,000 $ 940,868,000 $ (120,089,000) $ 1,107,961,000

================ ================ ================ ================



During the nine months ended September 30, 2002, the Company incurred
$2,778,000 in development costs.

In the fourth quarter of 2001, the Company identified two properties that
did not meet the Company's ongoing investment strategy. On October 8, 2002,
the Company sold one of these properties for net proceeds of $1.8 million
and a gain of approximately $100,000 which will be recognized in the fourth
quarter of 2002. The other property is currently being marketed and has
been designated as a property held for disposition at September 30, 2002.
The Company anticipates the net proceeds for the property currently being
marketed to result in a loss of approximately $900,000. Accordingly, it
recorded an impairment charge of $900,000 at September 30, 2002.

During the third quarter of 2002, the Company identified two additional
properties that did not meet the Company's ongoing investment criteria. One
property located in Overland Park, Kansas, was sold on August 26, 2002 for
$5.3 million, resulting in net proceeds of $5.1 million and a gain of
approximately $2 million. The other property, located in Landover Maryland,
was sold on October 1, 2002 for approximately $9.6 million, generating net
proceeds of $9.5 million and a gain of approximately $1.2 million which
will be recognized in the fourth quarter of 2002.

The following summarizes the condensed results of operations of the
properties held for disposition as of September 30, 2002, which are also
included in the condensed consolidated statements of income:

For the Nine Months
Ended September 30,
--------------------------------------------
2002 2001
------------------ ------------------
Rental income.................... $ 2,622,000 $ 2,625,000
Cost of operations............... (1,260,000) (1,278,000)
Net operating income............. $ 1,362,000 $ 1,347,000

The Company may, at times, bring properties to market for disposition that
it may or may not ultimately sell. These properties are not included in
properties held for disposition due to the probability that the disposition
will not occur (see note 8).

4. Leasing activity

The Company leases space in its real estate facilities to tenants under
non-cancelable leases generally ranging from one to ten years. Future
minimum rental revenues excluding recovery of expenses as of September 30,
2002 under these leases are as follows:

2002 (September - December)......... $ 45,002,000
2003................................ 153,202,000
2004................................ 119,297,000
2005................................ 84,785,000
2006................................ 51,989,000
Thereafter.......................... 82,370,000
--------------
$ 536,645,000
==============

In addition to minimum rental payments, tenants pay reimbursements for
their pro rata share of specified operating expenses, which amounted to
$21,028,000 and $16,846,000 for the nine months ended September 30, 2002
and 2001, respectively. These amounts are included as rental income and
cost of operations in the accompanying condensed consolidated statements of
income. Leases for approximately 5% of the Company's rental revenue is
subject to termination options with leases for approximately 3% of the
leased square footage exercisable through December 31, 2003. In general,
these leases provide for termination payments should the termination
options be exercised. The above table is prepared assuming such options are
not exercised.

5. Bank Loans

In October 2002, the Company extended its unsecured line of credit (the
"Credit Facility") with Wells Fargo Bank. The Credit Facility has a
borrowing limit of $100 million and an expiration date of August 1, 2005.
Interest on outstanding borrowings is payable monthly. At the option of the
Company, the rate of interest charged is equal to (i) the prime rate or
(ii) a rate ranging from the London Interbank Offered Rate ("LIBOR") plus
0.65% to LIBOR plus 1.25% depending on the Company's credit ratings and
coverage ratios, as defined (currently LIBOR plus 0.85%). In addition, the
Company is required to pay an annual commitment fee of 0.25% of the
borrowing limit. The Company had drawn $0 and $100 million on its line of
credit at September 30, 2002 and December 31, 2001, respectively.

The Credit Facility requires the Company to meet certain covenants
including (i) maintain a balance sheet leverage ratio (as defined) of less
than 0.50 to 1.00, (ii) maintain interest and fixed charge coverage ratios
(as defined) of not less than 2.25 to 1.00 and 1.75 to 1.00, respectively,
(iii) maintain a minimum total shareholders' equity (as defined) and (iv)
limit distributions to 95% of funds from operations (as defined) for any
four consecutive quarters. In addition, the Company is limited in its
ability to incur additional borrowings (the Company is required to maintain
unencumbered assets with an aggregate book value equal to or greater than
two times the Company's unsecured recourse debt) or sell assets. The
Company was in compliance with the covenants of the Credit Facility at
September 30, 2002.

In February 2002, the Company entered into a seven year $50 million
unsecured term note agreement with Fleet National Bank. The note bears
interest at LIBOR plus 1.45% per annum and is due on February 20, 2009. The
Company paid a one-time facility fee of 0.35% or $175,000 for the loan. The
Company used the proceeds from the loan to reduce the amount drawn on the
Credit Facility. During July, 2002, the Company entered into an interest

15



rate swap transaction which resulted in a fixed rate for the term loan
through July, 2004 at 4.46% per annum.

The unsecured note requires the Company to meet covenants that are
substantially the same as the covenants in the Credit Facility. The Company
was in compliance with the note covenants at September 30, 2002.

7. Minority interests

Common partnership units

The Company presents the accounts of PSB and the Operating Partnership on a
consolidated basis. Ownership interests in the Operating Partnership, other
than PSB's interest, are classified as minority interest in the
consolidated financial statements. Minority interest in income consists of
the minority interests' share of the consolidated operating results.

Beginning one year from the date of admission as a limited partner and
subject to certain limitations described below, each limited partner other
than PSB has the right to require the redemption of its partnership
interest.

A limited partner that exercises its redemption right will receive cash
from the Operating Partnership in an amount equal to the market value (as
defined in the Operating Partnership Agreement) of the partnership
interests redeemed. In lieu of the Operating Partnership redeeming the
partner for cash, PSB, as general partner, has the right to elect to
acquire the partnership interest directly from a limited partner exercising
its redemption right, in exchange for cash in the amount specified above or
by issuance of one share of PSB common stock for each unit of limited
partnership interest redeemed.

A limited partner cannot exercise its redemption right if delivery of
shares of PSB common stock would be prohibited under the applicable
articles of incorporation, or if the general partner believes that there is
a risk that delivery of shares of common stock would cause the general
partner to no longer qualify as a REIT, would cause a violation of the
applicable securities laws, or would result in the Operating Partnership no
longer being treated as a partnership for federal income tax purposes.

At September 30, 2002, there were 7,305,355 common units owned by PSI and
affiliated entities and which are accounted for as minority interests. On a
fully converted basis, assuming all 7,305,355 minority interest common
units were converted into shares of common stock of PSB at September 30,
2002, the minority interest units would convert into approximately 25% of
the common shares outstanding. At the end of each reporting period, the
Company determines the amount of equity (book value of net assets) which is
allocable to the minority interest based upon the ownership interest and an
adjustment is made to the minority interest, with a corresponding
adjustment to paid-in capital, to reflect the minority interests' equity in
the Company.

Preferred partnership units

Through the Operating Partnership, the Company has issued the following
preferred units in separate private placement transactions:




Date of Issuance Series Number of Units Face Value Preferred
Distribution Rate
--------------------------- ----------- ----------------- ------------------ ------------------


April, 1999 Series B 510 $ 12,750,000 8 7/8%

----------------- ------------------
7,910 $ 197,750,000
================= ==================


The Operating Partnership has the right to redeem preferred units on or
after the fifth anniversary of the applicable issuance date at the original
capital contribution plus the cumulative priority return, as defined, to
the redemption date to the extent not previously distributed. The preferred
units are exchangeable for Cumulative Redeemable Preferred Stock of the
respective series of PS Business Parks, Inc. on or after the tenth
anniversary of the date of issuance at the option of the Operating
Partnership or a majority of the holders of the respective preferred units.
The Cumulative Redeemable Preferred Stock will have the same distribution
rate and par value as the corresponding preferred units and will otherwise
have equivalent terms to the other series of preferred stock described in
Note 9.

8. Property management contracts

The Operating Partnership manages industrial, office and retail facilities
for PSI and affiliated entities. These facilities, all located in the
United States, operate under the "Public Storage" or "PS Business Parks"
names. In addition, the Operating Partnership manages properties for third
party owners and a joint venture.

The property management contracts provide for compensation of a percentage
of the gross revenues of the facilities managed. Under the supervision of
the property owners, the Operating Partnership coordinates rental policies,
rent collections, marketing activities, the purchase of equipment and
supplies, maintenance activities, and the selection and engagement of
vendors, suppliers and independent contractors. In addition, the Operating
Partnership assists and advises the property owners in establishing
policies for the hire, discharge and supervision of employees for the
operation of these facilities, including property managers and leasing,
billing and maintenance personnel.

The property management contract with PSI is for a seven year term with the
term being automatically extended one year on each anniversary. At any
time, either party may notify the other that the contract is not to be
extended, in which case the contract will expire on the first anniversary
of its then scheduled expiration date. The property management contracts
with affiliates of PSI are cancelable by the affiliates upon sixty days
notice and by the Operating Partnership upon seven years notice.

Company's Board of Directors until all events of default have been cured.
At September 30, 2002, there were no dividends in arrears.

a REIT, the preferred stock is not redeemable prior to the following dates:
Series A - April 30, 2004, Series D - May 10, 2006 and Series F - January
28, 2007. On or after the respective dates, the respective series of
preferred stock will be redeemable, at the option of the Company, in whole
or in part, at $25 per depositary share, plus any accrued and unpaid
dividends.

The Company may re-purchase shares of its preferred stock from time to time
on the open market in separately negotiated transactions. During the

Equity stock

In addition to common and preferred stock, the Company is authorized to
issue 100,000,000 shares of Equity Stock. The Articles of Incorporation
provide that the Equity Stock may be issued from time to time in one or
more series and give the Board of Directors broad authority to fix the
dividend and distribution rights, conversion and voting rights, redemption
provisions and liquidation rights of each series of Equity Stock.

10. Recent accounting pronouncements

In October 2001, the Financial Accounting Standards Board issued SFAS No.
144, "Accounting for the Impairment or Disposal of Long-Lived Assets." This
statement addresses financial accounting and reporting for the disposal of
long-lived assets and becomes effective for financial statements issued for
fiscal years beginning after December 15, 2001. The Company adopted SFAS
No. 144 on January 1, 2002 and its adoption resulted in the classification
of results of operations of certain assets disposed of or held for sale to
be reclassified as discontinued operations.

11. Commitments and contingencies

Substantially all of the Company's properties have been subjected to Phase
I environmental reviews. Such reviews have not revealed, nor is management
aware of, any probable or reasonably possible environmental costs that
management believes would have a material adverse effect on the Company's
business, assets or results of operations, nor is the Company aware of any
potentially material environmental liability, except as discussed below.

The Company acquired a property in Beaverton, Oregon ("Creekside Corporate
Park") in May 1998. A portion of Creekside Corporate Park, as well as
properties adjacent to Creekside Corporate Park, were the subject of an
environmental investigation conducted by two current and past
owner/operators of an industrial facility on adjacent property, pursuant to
a Consent Decree issued by the Oregon Department of Environmental Quality
("ODEQ"). Results of that investigation indicate that the contamination
from the industrial facility has migrated onto portions of Creekside
Corporate Park owned by the Company. There is no evidence that the
Company's past or current use of the Creekside Corporate Park property
contributed in any way to the contamination that is the subject of the
current investigation, nor has the ODEQ alleged any such contribution.

The Company, which is not a party to the Consent Decree, executed separate
Access Agreements with the two owner/operators to allow access to portions
of Creekside Corporate Park to conduct the required sampling and testing,
and to permit one of the owner/operators subject to the Consent Decree to
construct, install and operate a groundwater treatment system on a portion
of Creekside Corporate Park owned by the Company. Operation and maintenance
of this groundwater treatment system, which is required by the Interim
Remedial Action Plan approved by ODEQ, is the sole responsibility of the
owner/operator, and not the Company.

Based on the remedial investigation/feasibility study, ODEQ has selected a
final remedy that would include permanent treatment of contaminants in the
groundwater, including expanded groundwater extraction and treatment on all
parcels of the former industrial property, including portions of Creekside
Corporate Park. The estimated cost of this remedy is $2.8 million over a
30-year time period.

ODEQ has commenced negotiations with the two owner/operators and the
Company, along with other similarly situated owners of property adjacent to
the industrial facility, to reach a settlement pursuant to which the
selected remedy be implemented. It is possible that the ODEQ could require
the Company to participate in the implementation of removal or remedial
actions that may be required on the Company's property, or to pay a portion
of the costs to do so. One of the two owner/operators that conducted the
investigation filed for Chapter 11 bankruptcy protection. It is not clear

20



at this point what impact, if any, this filing will have on the
negotiations regarding remedy implementation.

In the event the Company is ultimately deemed responsible for any costs
relating to this matter, the Company believes that it may have recourse
against the party from whom the property was purchased. In addition, the
Company believes it may have recourse against other potentially responsible
parties, including, but not limited to, one or both of the owner/operators
of the adjacent industrial facility. Based on recent discussions with the
ODEQ and other potentially responsible parties, the Company has estimated
its share of the costs of the remediation at $250,000. The Company has
accrued these estimated costs and included the expense in general and
administrative costs.

Although environmental investigations conducted to date on other properties
owned by the Company have not revealed any environmental liability that the
Company believes would have a material adverse effect on the Company's
business, assets or results of operations, and the Company is not aware of
any such liability, it is possible that these investigations did not reveal
all environmental liabilities or that there are material environmental
liabilities of which the Company is unaware. No assurances can be given
that (i) future laws, ordinances, or regulations will not impose any
material environmental liability, or (ii) the current environmental
condition of the Company's properties has not been, or will not be,
affected by tenants and occupants of the Company's properties, by the
condition of properties in the vicinity of the Company's properties, or by
third parties unrelated to the Company.

The Company currently is neither subject to any other material litigation
nor, to management's knowledge, is any material litigation currently
threatened against the Company other than routine litigation and
administrative proceedings arising in the ordinary course of business.
Management believes that the environmental issues will not have a material
adverse impact on the Company's condensed consolidated financial position
or results of operations.

12. Subsequent Event

During October, 2002, the Operating Partnership completed a private
placement of 800,000 preferred units with a preferred distribution rate of
7.95%. The net proceeds from the placement of preferred units were
approximately $19.5 million.

In October 2002, the Company extended its unsecured line of credit (the
"Credit Facility") with Wells Fargo Bank. The Credit Facility has a
borrowing limit of $100 million and an expiration date of August 1, 2005.
Interest on outstanding borrowings is payable monthly. At the option of the
Company, the rate of interest charged is equal to (i) the prime rate or
(ii) a rate ranging from the London Interbank Offered Rate ("LIBOR") plus
0.75% to LIBOR plus 1.25% depending on the Company's credit ratings and
coverage ratios, as defined (currently LIBOR plus 0.85%). In addition, the
Company is required to pay an annual commitment fee of up to 0.25% of the
borrowing limit. In connection with the extension, the Company paid Wells
Fargo Bank a one-time fee of $320,000. The Company had drawn $0 and $100
million on its line of credit at September 30, 2002 and December 31, 2001,
respectively.

factors affecting such forward-looking statements.

Overview
- --------

CRITICAL ACCOUNTING POLICIES AND ESTIMATES: Our significant accounting
policies are described in Note 2 to the condensed consolidated financial
statements included in this Form 10-Q. We believe our most critical accounting
policies relate to revenue recognition, allowance for doubtful accounts,
impairment of long-lived assets, depreciation, accrual of operating expenses and
accruals for contingencies each of which we discuss below.

REVENUE RECOGNITION: We recognize revenue in accordance with Staff
Accounting Bulletin No. 101 of the Securities and Exchange Commission,
Revenue Recognition in Financial Statements (SAB 101), as amended. SAB
101 requires that four basic criteria must be met before revenue can be
recognized. The criteria is that persuasive evidence of an arrangement
exists, the delivery has occurred or services rendered, the fee is
fixed and determinable and collectibility is reasonably assured.

ALLOWANCE FOR DOUBTFUL ACCOUNTS: Rental revenue from our tenants is our
principal source of revenue. We monitor the collectibility of our
receivable balances including the deferred rent receivable on an
on-going basis. Based on these reviews, we establish a provision, and
maintain an allowance, for doubtful accounts for estimated losses
resulting from the possible inability of our tenants to make required
rent payments to us. An allowance for doubtful accounts is recorded
during each period and is netted against rental revenue in our
consolidated statements of operations. The allowance for doubtful
accounts, which represents the cumulative allowances less write-offs of
uncollectible rent, is netted against tenant and other receivables on
our consolidated balance sheets. If we incorrectly determine the
collectibility of our revenue, the timing and amount of our reported
revenue could be affected.

IMPAIRMENT OF LONG-LIVED ASSETS: We are required to record at fair
value any of our long-lived assets that we have determined to be
permanently impaired. Our long-lived assets consist primarily of our
investments in real estate. The fair value of our investments in real
estate depends on the future cash flows from operations of the
properties. If the estimated future cash flow of the property results
in a determination that the fair value is less than our carrying value,
an impairment may be recognized if we determine the loss to be
permanent. As of September 30, 2002, the Company does not consider any
of its long-lived assets included in continuing operations to be
impaired. The Company has recognized an impairment loss of $900,000 on
one of its properties held for sale because the net proceeds from sale
is expected to be less than the carrying value. An impairment loss
could have a material adverse impact on our financial condition and
results of operations.

DEPRECIATION: We compute depreciation on our buildings and equipment
using the straight-line method based on estimated useful lives of
generally 30 and 5 years. A significant portion of the acquisition cost
of each property is allocated to building and building components
(usually 80-85%). The allocation of the acquisition cost to building
and its components and the determination of the useful life are based

22



on management's estimates. If we do not allocate appropriately to
building or related components or incorrectly estimate the useful life
of our properties, the timing and/or the amount of depreciation expense
will be affected. In addition, the net book value of real estate assets
could be over or understated. The statement of cash flows, however,
would not be affected.

ACCRUALS OF OPERATING EXPENSES: The Company accrues for property tax
expenses, performance bonuses and other operating expenses each quarter
based on historical trends and anticipated disbursements. If these
estimates are incorrect, the timing of expense recognition will be
affected.

ACCRUALS FOR CONTINGENCIES: The Company is exposed to business and
legal liability risks with respect to events that may have occurred,
but in accordance with generally accepted accounting principles has not
accrued for such potential liabilities because the loss is either not
probable or not estimable. Future events and the result of pending
litigation could result in such potential losses becoming probable and
estimable, which could have a material adverse impact on our financial
condition of results of operations.

QUALIFICATION AS A REIT - INCOME TAX EXPENSE: We believe that we have
been organized and operated, and we intend to continue to operate, as a
qualifying REIT under the Internal Revenue Code and applicable state
laws. A qualifying REIT generally does not pay corporate level income
taxes on its taxable income that is distributed to its shareholders,
and accordingly, we do not pay or record as an expense income tax on
the share of our taxable income that is distributed to shareholders.

Given the complex nature of the REIT qualification requirements, the
ongoing importance of factual determinations and the possibility of
future changes in our circumstances, we cannot provide any assurance
that we actually have satisfied or will satisfy the requirements for
taxation as a REIT for any particular taxable year. For any taxable
year that we fail or failed to qualify as a REIT and applicable relief
provisions did not apply, we would be taxed at the regular corporate
rates on all of our taxable income, whether or not we made or make any
distributions to our shareholders. Any resulting requirement to pay
corporate income tax, including any applicable penalties or interest,
could have a material adverse impact on our financial condition or
results of operations. Unless entitled to relief under specific
statutory provisions, we also would be disqualified from taxation as a
REIT for the four taxable years following the year during which
qualifications was lost. There can be no assurance that we would be
entitled to any statutory relief.

EFFECT OF ECONOMIC CONDITIONS ON THE COMPANY'S OPERATIONS: During 2001
and continuing into 2002, the Company has been affected by the slowdown in
economic activity in the United States in most of its primary markets. These
effects were exacerbated by the terrorist attacks of September 11, 2001 and the
related aftermath. These effects include a decline in occupancy rates, a
reduction in market rental rates throughout the portfolio, slower than expected
lease-up of the Company's development properties, increased tenant defaults and
the termination of leases pursuant to early termination options.

The reduction in occupancies and market rental rates has been the
result of several factors related to general economic conditions. There are more
businesses contracting than expanding, more businesses failing than starting-up
and general uncertainty for businesses, resulting in slower decision-making and
requests for shorter-term leases. There is also more competing vacant space,
including substantial amounts of sub-lease space, in many of the Company's
markets. Many of the Company's properties have lower vacancy rates than the
average rates for the markets in which they are located; consequently, the
Company may have difficulty in maintaining its occupancy rates as leases expire.
An extended economic slowdown will put additional downward pressure on
occupancies and market rental rates. The economic slowdown and the abundance of
space alternatives available to customers has led to pressure for greater rent
concessions, more generous tenant improvement allowances and higher broker
commissions.

23



These economic conditions have also resulted in the erosion of tenant
credit quality throughout the portfolio. As a result, more tenants are
contacting us regarding their economic viability, including those that could be
material to our revenue base and more tenants are electing to terminate their
leases early under lease termination options. To a certain extent, these
economic conditions have affected two of our largest tenants representing a
combined 2% of the Company's revenues. Leases with Worldcom and two related
entities generate 0.9% of the Company's revenues. Worldcom's recent bankruptcy
may adversely affect the continuity of that revenue. Another large tenant
representing approximately 1% of revenues has recently defaulted on its lease
obligations and has requested a modification of its lease. The Company is
currently negotiating with the tenant to resolve the matter and the outcome is
unknown. Several other of our large tenants have contacted us, requesting early
termination of their lease, rent reduction in space under lease, rent deferment
or abatement. At this time, the Company cannot anticipate what impact, if any,
the ultimate outcome of these discussions will have on our operating results.

The Company's two development properties were 57% leased in the
aggregate as of September 30, 2002, but they have not been leased as rapidly as
the Company had anticipated. The development properties consist of a 141,000
square foot flex development in Northern Virginia that was 80% leased, and a
97,000 square foot development in the Beaverton submarket of Portland, Oregon
that was 26% leased.

GROWTH OF THE COMPANY'S OPERATIONS: During 2001 and continuing into
2002, the Company focused on maximizing cash flow from its existing core
portfolio of properties, seeking to expand its presence in existing markets
through strategic acquisitions and developments and strengthening its balance
sheet, primarily through the issuance of preferred stock/units. The Company has
historically maintained low debt and overall leverage levels, including
preferred stock/units, which should give it the flexibility for future growth
without the issuance of additional common stock.

During the nine months ended September 30, 2002, the Company did not
complete any acquisitions. The Company plans to continue to seek to build its
presence in existing markets by acquiring high quality facilities in selected
markets. The Company targets properties with below market rents which may offer
it growth in rental rates above market averages and which offer the Company the
ability to achieve economies of scale resulting in more efficient operations.

During the third quarter of 2002, one property located in Overland
Park, Kansas totaling 62,000 square feet was sold on August 26, 2002 for $5.3
million resulting in net proceeds of $5.1 million and a gain of approximately $2
million for financial accounting purposes. This was the Company's only facility
in Kansas.

During October, 2002, the Company sold a property located in Landover,
Maryland totaling 125,000 square feet. The property was sold for approximately
$9.6 million generating net proceeds of $9.5 million and a gain of approximately
$1.2 million for financial accounting purposes which will be recognized in the
fourth quarter of 2002. In addition, the Company sold a property located in San
Antonio, Texas totaling 43,000 square feet. The property was sold for
approximately $2 million generating net proceeds of $1.8 million and a gain of
approximately $100,000 for financial accounting purposes which will be
recognized in the fourth quarter of 2002.

During 2001, the Company added approximately 2.2 million square feet of
space to its portfolio at an aggregate cost of approximately $303 million. These
acquisitions increased the Company's presence in its existing markets. The
Company acquired 658,000 square feet in Northern Virginia for approximately $88
million, 685,000 square feet in Oregon for approximately $88 million and 905,000
square feet in Maryland for approximately $127 million. In addition, the Company
completed development of three properties totaling 339,000 square feet in
Northern Virginia, Portland and Dallas for approximately $28.5 million. The
Company also disposed of a property aggregating 77,000 square feet for
approximately $9 million. The Company also formed a joint venture to own and
operate an industrial park. This park, consisting of 294,000 square feet, was
acquired in December 2000 at a cost of approximately $14.4 million and was
contributed to the joint venture at its original cost for a 25% equity interest
in the joint venture.

Results of Operations
- ---------------------

RESULTS OF OPERATIONS: Net income for the three months ended September
30, 2002 was $13,844,000 compared to $12,849,000 for the same period in 2001.
Net income allocable to common shareholders (net income less preferred stock
dividends) for the three months ended September 30, 2002 was $9,911,000 compared
to $10,010,000 for the same period in 2001. Net income per common share on a
diluted basis was $0.46 for the three months ended September 30, 2002 compared
to $0.45 for the same period in 2001 (based on weighted average diluted common
shares outstanding of 21,772,000 and 22,295,000 at September 30, 2002 and 2001,
respectively). Net income per common share, excluding income from discontinued
operations and properties held for sale, was $0.43 on both a basic and diluted
basis for the three months ended September 30, 2002 compared to $0.43 basic and
$0.42 diluted for the same period in 2001. The increase was due to gains on
disposition of assets offset by an increase in depreciation expense as a result
of property acquisitions in 2001 and an impairment charge for a property held
for sale.

Net income for the nine months ended September 30, 2002 was $44,018,000
compared to $37,144,000 for the same period in 2001. Net income allocable to
common shareholders (net income less preferred stock dividends) for the nine
months ended September 30, 2002 was $32,535,000 compared to $31,130,000 for the
same period in 2001. Net income per common share on a diluted basis was $1.49
for the nine months ended September 30, 2002 compared to $1.37 for the same
period in 2001 (based on weighted average diluted common shares outstanding of
21,763,000 and 22,685,000, respectively). Net income per common share, excluding
income from discontinued operations and properties held for sale, was $1.43
basic or $1.42 on a diluted basis for the nine months ended September 30, 2002
compared to $1.30 basic and diluted for the same period in 2001. Net income
allocable to common shareholders for the first nine months of 2002 included
recognizing gains on dispositions of properties totaling $7.4 million or $0.26
per share, the Company's share of gains on disposition of four buildings in its
joint venture of $265,000 or approximately $0.01 per share and a $900,000
impairment charge or approximately $0.03 per share, for one of its properties
held for sale that was determined to have a carrying value greater than its
anticipated sales price. The net income per diluted share before the recognition
of these gains on dispositions and impairment charges was $1.26 or $0.11 less
than the same period in 2001. The decrease was the result of an increase in
depreciation expense as a result of property acquisitions in 2001, offset
partially by the net operating income from the acquired properties, net of
financing costs.

25



The Company's property operations account for almost all of the net
operating income earned by the Company. The following table presents the

SUPPLEMENTAL PROPERTY DATE AND TRENDS: In order to evaluate the
performance of the Company's overall portfolio, management analyzes the
operating performance of a consistent group of properties constituting 11.8
million net rentable square feet ("Same Park" facilities). The Company currently
has an ownership interest in these properties and has owned and operated them
for the comparable periods. These properties do not include properties that have
been acquired or sold during 2001 and 2002. The "Same Park" facilities represent
approximately 80% of the weighted average square footage of the Company's
portfolio at September 30, 2002.

The increases noted above reflect the performance of the Company's
existing markets. Northern California benefited from strong results in the
Sacramento portfolio combined with the renewals in 2001 of our three largest
leases in Northern California. Decreases reflected above were primarily due to
declining occupancy levels and declining rental rates. Southern Texas continued
to experience declines in occupancy. The decrease in Virginia is primarily the
result of a building leased to the U.S. Government that was not paying rent
until October 2002. In addition, vacancy rates increased and rents decreased in
Virginia due to the softness in the Herndon and Chantilly submarkets. Total
revenues include rental income that was determined to be uncollectible and was
written-off in the amount of $106,000 and $101,000 for the three months ended
September 30, 2002 and 2001, respectively.

Virginia due to the softness in the Herndon and Chantilly submarkets. The
substantial decline in NOI from our peripheral markets is primarily the result
of the timing of certain expenses during the first quarter. Total revenues
include rental income that was determined to be uncollectible and was

29



written-off in the amount of $389,000 and $328,000 for the nine months ended
September 30, 2002 and 2001, respectively.

FACILITY MANAGEMENT OPERATIONS: The Company's facility management
accounts for a small portion of the Company's net operating income. During the
three months ended September 30, 2002, $147,000 in net operating income was
recognized from facility management operations compared to $132,000 for the same
period in 2001. During the nine months ended September 30, 2002, the Company
generated net operating income of $443,000 compared to $388,000 for the same
period in 2001. Facility management fees have increased due primarily to
additional properties brought under management.

BUSINESS SERVICES: Business services include construction management
fees and fees from telecommunications service providers. During the three months
ended September 30, 2002, Business Services generated a net operating loss of
$64,000 compared to a net operating loss of $72,000 for the same period in 2001.
During the nine months ended September 30, 2002, Business Services generated a
net operating loss of $283,000 compared to net operating loss of $152,000 for
the same period in 2001. Business services revenue has declined primarily due to
the bankruptcies of Darwin Networks, Winstar and Teligent, telecommunication
service providers.

INTEREST AND OTHER INCOME: Interest and other income reflects earnings
on cash balances and dividends on marketable securities. Interest income was
$47,000 for the three months ended September 30, 2002 compared to $346,000 for
the same period in 2001. Interest income was $643,000 for the nine months ended
September 30, 2002 compared to $1,659,000 for the same period in 2001. The
decrease is attributable to lower average cash balances and interest rates.
Average cash balances and effective interest rates for the three months ended
September 30, 2002 were approximately $10 million and 2.0% compared to $39
million and 3.5% for the same period in 2001. Average cash balances and
effective interest rates for the nine months ended September 30, 2002 were
approximately $20 million and 2.1% compared to $51 million and 4.4% for the same
period in 2001.

COST OF OPERATIONS: Cost of operations for the three months ended
September 30, 2002 was $12,953,000 compared to $11,488,000 for the same period
in 2001. Cost of operations for the nine months ended September 30, 2002 was
$39,396,000 compared to $31,350,000 for the same period in 2001. The increase is
due primarily to the growth in the square footage of the Company's portfolio of
properties. Costs of operations for those properties in our "Same Park"
facilities decreased 0.4% for the three months ended September 30, 2002 and
increased 3.3% for the nine months ended September 30, 2002. Cost of operations
as a percentage of rental income for the nine months ended September 30, 2002
was fairly consistent at 26.5% compared to 26.4% for the same period in 2001.

DEPRECIATION AND AMORTIZATION EXPENSE: Depreciation and amortization
expense for the three months ended September 30, 2002 was $14,595,000 compared
to $10,679,000 for the same period in 2001. Depreciation and amortization
expense for the nine months ended September 30, 2001 was $42,885,000 compared to
$30,058,000 for the same period in 2001. The increase is primarily due to
depreciation expense on real estate facilities acquired or developed during
2001.

GENERAL AND ADMINISTRATIVE EXPENSE: General and administrative expense
was $1,194,000 for the three months ended September 30, 2002 compared to
$1,037,000 for the same period in 2001. General and administrative expense was
$3,398,000 for the nine months ended September 30, 2002 compared to $3,157,000
for the same period in 2001. Included in general and administrative costs are
acquisition costs. Acquisition expenses were $102,000 and $136,000 for the three
months ended September 30, 2002 and 2001, respectively. Acquisition expenses
were $416,000 and $453,000 for the nine months ended September 30, 2002 and
2001, respectively. In addition, general and administrative expenses also
includes approximately $343,000 in stock option compensation expense for the
nine months ended September 30, 2002 related to stock options granted after
January 1, 2002.

INTEREST EXPENSE: Interest expense was $1,115,000 for the three months
ended September 30, 2002 compared to $538,000 for the same period in 2001.

30



Interest expense was $4,098,000 for the nine months ended September 30, 2002
compared to $932,000 for the same period in 2001. The increase is primarily
attributable to increased debt balances in 2002 due to the use of the Company's
credit facilities to fund acquisitions completed during the fourth quarter of
2001. Interest expense of $0 and $103,000 was capitalized as part of building
costs associated with properties under development during the three months ended
September 30, 2002 and 2001, respectively. Interest expense of $288,000 and
$1,001,000 was capitalized as part of building costs associated with properties
under development during the nine months ended September 30, 2002 and 2001,
respectively. As of September 30, 2002, all developed properties had been shell
complete for at least one year. The Company has, therefore, discontinued
capitalization of interest on these facilities.

GAIN ON DISPOSITION OF REAL ESTATE: Gain on sale of real estate was
$7,407,000 for the nine months ended September 30, 2002. The gain primarily
results from the Company's disposal of a property in San Diego for approximately
$9 million in November 2001 and deferral of gain of $5,366,000 which was later
recognized in the first quarter of 2002 when the buyer of the property obtained
third party financing for the property and paid off most of its note to the
Company. In addition, the Company sold a property located in Overland Park,
Kansas for approximately $5.3 million, resulting in a gain of approximately $2
million.

GAIN ON INVESTMENT IN MARKETABLE SECURITIES: Gain on investments in
marketable securities was $41,000 for the nine months ended September 30, 2002
compared to $15,000 for the same period in 2001.

IMPAIRMENT CHARGE ON PROPERTY HELD FOR SALE: The Company has recognized
an impairment loss of $900,000 in the third quarter of 2002 on one of its
properties held for sale because the net proceeds from the sale are expected to
be less than the carrying value.

MINORITY INTEREST IN INCOME: Minority interest in income reflects the
income allocable to equity interests in the Operating Partnership that are not
owned by the Company. Minority interest in income was $7,768,000 ($4,412,000
allocated to preferred unitholders and $3,356,000 allocated to common
unitholders) for the three months ended September 30, 2002 compared to
$6,591,000 ($3,323,000 allocated to preferred unitholders and $3,268,000
allocated to common unitholders) for the same period in 2001. Minority interest
income for the nine months ended September 30, 2001 was $24,256,000 ($13,237,000
allocated to preferred unitholders and $11,019,000 allocated to common
unitholders) compared to $19,743,000 ($9,696,000 allocated to preferred
unitholders and $10,047,000 allocated to common unitholders) for the same period
in 2001. The increase in minority interest in income is due primarily to the
issuance of preferred operating partnership units during 2001 and higher
earnings at the Operating Partnership level.

Liquidity and Capital Resources
- -------------------------------

Net cash provided by operating activities for the nine months ended
September 30, 2002 and 2001 was $97,784,000 and $92,107,000, respectively.
Management believes that the Company's internally generated net cash provided by
operating activities will continue to be sufficient to enable it to meet its
operating expenses, capital improvements and debt service requirements and to
maintain the current level of distributions to shareholders.

The following table summarizes the Company's cash flow from operating
activities:

The Company's capital structure is characterized by a relatively low
level of leverage. As of September 30, 2002, the Company had six fixed rate
mortgage notes payable totaling $27,720,000, which represented 1.9% of its total
capitalization (based on book value, including minority interest and debt). The
weighted average interest rate for the mortgage notes is 7.50% per annum.

The Company used its short-term borrowing capacity to complete
acquisitions totaling $303 million in 2001. The Company borrowed $100 million
from its line of credit and $35 million from PSI. The remaining balance was
funded from proceeds of the issuance of preferred stock and preferred units in
the Operating Partnership totaling $116 million and existing cash of $52
million. During January 2002, the Company issued 2,000,000 depositary shares,
each representing 1/1,000 of a share of 8 3/4% Cumulative Preferred Stock,
Series F, resulting in net proceeds of $48.3 million. This was used to repay PSI
and to increase financial flexibility.

In February 2002, the Company entered into a seven year $50 million
term loan agreement with Fleet National Bank. The note bears interest at LIBOR
plus 1.45% and is due on February 20, 2009. The Company paid a one-time fee of
0.35% or $175,000 for the facility. The Company used the proceeds of the loan to

32



reduce the amount drawn on its Credit Facility with Wells Fargo Bank. In July,
2002, the Company entered into an interest rate swap transaction which had the
effect of fixing the rate on the term loan for two years at 4.46% per annum.

During October, 2002, the Operating Partnership completed a private
placement of 800,000 preferred units with a preferred distribution rate of
7.95%. The net proceeds from the placement of preferred units were approximately
$19.5 million.

The Company's funding strategy is to use permanent capital, including
common and preferred stock, and internally generated retained cash flows. In
addition, the Company may sell properties that no longer meet its investment
criteria. The Company may finance acquisitions on a temporary basis with
borrowings from its Credit Facility. The Company targets a leverage ratio of 40%
(defined as debt and preferred equity as a percentage of market capitalization).
In addition, the Company targets a ratio of Funds from Operations ("FFO") to
combined fixed charges and preferred distributions of 3.0 to 1.0. As of
September 30, 2002, the leverage ratio was 31% and the FFO to fixed charges and
preferred distributions coverage ratio was 3.8 to 1.0 for the three months ended
September 30, 2002.

In October 2002, the Company extended its Credit Facility with Wells
Fargo Bank. The Credit Facility has a borrowing limit of $100 million and an
expiration date of August 1, 2005. Interest on outstanding borrowings is payable
monthly. At the option of the Company, the rate of interest charged is equal to
(i) the prime rate or (ii) a rate ranging from the London Interbank Offered Rate
("LIBOR") plus 0.65% to LIBOR plus 1.25% depending on the Company's credit
ratings and coverage ratios, as defined (currently LIBOR plus 0.85%). In
addition, the Company is required to pay an annual commitment fee of up to 0.25%
of the borrowing limit. In connection with the extension, the Company paid Wells
Fargo Bank a one-time fee of $320,000. As of September 30, 2002, there was no
balance outstanding on the Credit Facility.

FUNDS FROM OPERATIONS: FFO is defined as net income, computed in
accordance with generally accepted accounting principles ("GAAP"), before
depreciation, amortization, minority interest in income, straight line rent
adjustments and extraordinary or non-recurring items. FFO is presented because
the Company considers FFO to be a useful measure of the operating performance of
a REIT which, together with net income and cash flows, provides investors with a
basis to evaluate the operating and cash flow performances of a REIT. FFO does
not represent net income or cash flows from operations as defined by GAAP. FFO
does not take into consideration scheduled principal payments on debt or capital
improvements. The Company believes that in order to facilitate a clear
understanding of the Company's operating results, FFO should be analyzed in
conjunction with net income as presented in the Company's consolidated financial
statements included elsewhere in this Form 10-Q. Accordingly, FFO is not
necessarily a substitute for cash flow or net income as a measure of liquidity
or operating performance or ability to make acquisitions and capital
improvements or ability to make distributions or debt principal payments.

33



FFO as computed and disclosed by the Company may not be comparable to
FFO computed and disclosed by other REITs. The Company calculates FFO as
follows:

CAPITAL EXPENDITURES: On a recurring annual basis, the Company expects
to incur between $0.90 and $1.20 per square foot in recurring capital
expenditures ($13-$18 million based on square footage at September 30, 2002). In
addition, the Company expects to make $5 million in additional capital
expenditures during the remainder of 2002. These investments include
improvements to bring acquired properties up to the Company's standards of $2
million, first generation tenant improvements and leasing commissions on
development properties of $1 million and the renovation of properties in
Southern California, Northern Virginia, Arizona and Maryland totaling $2
million. During the nine months ended September 30, 2002, the Company incurred
approximately $20.2 million in capital expenditures. These included $13.7
million in maintenance capital expenditures, tenant improvements and capitalized
leasing commissions, $0.7 million to bring acquired properties up to the
Company's standards, $2.8 million in first generation tenant improvements and
leasing commissions on developed properties and $3.0 million in property
renovations.

STOCK REPURCHASE: The Company's Board of Directors has authorized the
repurchase from time to time of up to 4,500,000 shares of the Company's common
stock on the open market or in privately negotiated transactions. The Company
has not repurchased any common stock in 2002. In addition, the Company may
re-purchase shares of its preferred stock from time to time on the open market
in separately negotiated transactions. During the quarter ended June 30, 2002,
the Company repurchased 500 shares of Series D preferred stock with a face value
of $12,500 for $12,823 or $25.65 per share. During the quarter ended September
30, 2002, the Company repurchased 1,500 shares of Series A preferred stock with
a face value of $37,500 for $38,266 or $25.51 per share.

DISTRIBUTIONS: The Company has elected and intends to qualify as a REIT
for federal income tax purposes. In order to maintain its status as a REIT, the
Company must meet, among other tests, sources of income, share ownership and
certain asset tests. As a REIT, the Company is not taxed on that portion of its
taxable income that is distributed to its shareholders provided that at least
90% of its taxable income is distributed to its shareholders prior to filing of
its tax return.

RELATED PARTY TRANSACTIONS: At September 30, 2002, PSI owns 25% of the
outstanding shares of the Company's common stock (44% upon conversion of its
interest in the Operating Partnership) and 25% of the outstanding common units
of the Operating Partnership (100% of the common units not owned by the

34



Company). Ronald L. Havner, Jr., the Company's chairman and chief executive
officer, is also the vice-chairman, chief executive officer and a director of
PSI. As of December 31, 2001, the Company had $35 million in short-term
borrowings from PSI. The notes bore interest at 3.25% and were repaid as of
January 28, 2002. Pursuant to a cost sharing and administrative services
agreement, the Company shares costs with PSI and affiliated entities for certain
insurance and administrative services. These costs are allocated by PSI and its
affiliates in accordance with a methodology intended to fairly allocate those
costs. In addition, the Company provides property management services for
properties owned by PSI and its affiliates for a fee of 5% of the gross revenues
of such properties in addition to reimbursement of direct costs. Also, in June
2002, the Company purchased land adjacent to its Metro Park North facility from
PSI at PSI's cost (approximately $1,100,000). Finally, the Company combines its
insurance purchasing power with PSI through a captive insurance company
controlled by PSI, STOR-Re Mutual Insurance Corporation ("Stor-Re"). Stor-Re
provides limited property and liability insurance to the Company at commercially
competitive rates. The Company and PSI also utilize unaffiliated insurance
carriers to provide property and liability insurance in excess of Stor-Re's
limitations.

ITEM 2A. RISK FACTORS

In addition to the other information in this Form 10-Q, the following
factors should be considered in evaluating our company and our business.

PSI has significant influence over us.
- --------------------------------------

PSI OWNS A SUBSTANTIAL NUMBER OF OUR SHARES AND OF THE UNITS OF OUR
OPERATING PARTNERSHIP: At September 30, 2002, PSI and its affiliates owned 25%
of the outstanding shares of our common stock (44% upon conversion of its
interest in our operating partnership) and 25% of the outstanding common units
of our operating partnership (100% of the common units not owned by us). Also,
Ronald L. Havner, Jr., our chairman of the board and chief executive officer, is
also vice-chairman, chief executive officer and a director of PSI and Harvey
Lenkin, one of our directors, is president and a director of PSI. Consequently,
PSI has the ability to significantly influence all matters submitted to a vote
of our shareholders, including electing directors, changing our articles of
incorporation, dissolving and approving other extraordinary transactions such as
mergers, and all matters requiring the consent of the limited partners of the
operating partnership. In addition, PSI's ownership may make it more difficult
for another party to take over our company without PSI's approval.

Provisions in our organizational documents may prevent changes in control.
- --------------------------------------------------------------------------

OUR ARTICLES GENERALLY PROHIBIT OWNING MORE THAN 7% OF OUR SHARES: Our
articles of incorporation restrict the number of shares that may be owned by any
person (other than PSI and certain other specified shareholders), and the
partnership agreement of our operating partnership contains an anti-takeover
provision. No shareholder (other than PSI and certain other specified
shareholders) may own more than 7% of the outstanding shares of our common
stock, unless our board of directors waives this limitation. We imposed this
limitation to avoid, to the extent possible, a concentration of ownership that
might jeopardize our ability to qualify as a real estate investment trust, or
REIT. This limitation, however, also makes a change of control much more
difficult even if it may be favorable to our public shareholders. These
provisions will prevent future takeover attempts not approved by PSI even if a
majority of our public shareholders consider it to be in their best interests
because they would receive a premium for their shares over the shares' then
market value or for other reasons.

OUR BOARD CAN SET THE TERMS OF CERTAIN SECURITIES WITHOUT SHAREHOLDER
APPROVAL: Our board of directors is authorized, without shareholder approval, to
issue up to 50,000,000 shares of preferred stock and up to 100,000,000 shares of
equity stock, in each case in one or more series. Our board has the right to set
the terms of each of these series of stock. Consequently, the board could set
the terms of a series of stock that could make it difficult (if not impossible)
for another party to take over our company even if it might be favorable to our
public shareholders. We can also cause our operating partnership to issue
additional interests for cash or in exchange for property.

THE PARTNERSHIP AGREEMENT OF OUR OPERATING PARTNERSHIP RESTRICTS
MERGERS: The partnership agreement of our operating partnership provides that
generally we may not merge or engage in a similar transaction unless limited
partners of our operating partnership are entitled to receive the same
proportionate payments as our shareholders. In addition, we have agreed not to
merge with another entity unless the merger would have been approved had the
limited partners been able to vote together with our shareholders, which has the
effect of increasing PSI's influence over us due to PSI's ownership of operating
partnership units. These provisions may make it more difficult for us to merge
with another entity.

Our operating partnership poses additional risks to us.
- -------------------------------------------------------

Limited partners of our operating partnership, including PSI, have the
right to vote on certain changes to the partnership agreement. They may vote in
a way that is contrary to the interest of our shareholders. Also, as general

36



partner of our operating partnership, we are required to protect the interests
of the limited partners of our operating partnership. The interests of the
limited partners and of our shareholders may differ.

37



We cannot sell certain properties without PSI's approval.
- ---------------------------------------------------------

Before 2007, we may not sell 12 specified properties without PSI's
approval. Since PSI would be taxed on a sale of these properties, the interests
of PSI and our other shareholders may differ as to the best time to sell.

An institutional investor has registration rights.
- --------------------------------------------------

An institutional investor has the right to require registration of its
shares.

We would incur adverse tax consequences if we fail to qualify as a REIT.
- ------------------------------------------------------------------------

OUR CASH FLOW WOULD BE REDUCED IF WE FAIL TO QUALIFY AS A REIT: While
we believe that we have qualified since 1990 to be taxed as a REIT, and will
continue to be qualified, we cannot be certain of doing so. To continue to
qualify as a REIT, we need to satisfy certain requirements under the federal
income tax laws relating to our income, assets, and distributions to
shareholders and shareholder base. In this regard, the share ownership limits in
our articles of incorporation do not necessarily ensure that our shareholder
base is sufficiently diverse for us to qualify as a REIT. For any year we fail
to qualify as a REIT, we would be taxed at regular corporate tax rates on our
taxable income unless certain relief provisions apply. Taxes would reduce our
cash available for distributions to shareholders or for reinvestment, which
could adversely affect us and our shareholders. Also we would not be allowed to
elect REIT status for five years after we fail to qualify unless certain relief
provisions apply.

OUR CASH FLOW WOULD BE REDUCED IF OUR PREDECESSOR FAILED TO QUALIFY AS
A REIT: For us to qualify to be taxed as a REIT, our predecessor, American
Office Park Properties, also needed to qualify to be taxed as a REIT. We believe
American Office Park Properties qualified as a REIT beginning in 1997 until its
March 1998 merger with us. If it is determined that it did not qualify as a
REIT, we could also lose our REIT qualification. Before 1997, our predecessor
was a taxable corporation and, to qualify as a REIT, was required to distribute
all of its cumulative retained profits before the end of 1996. Because a
determination of the precise amount of profits retained by a company over a
sustained period of time is very difficult, there is some risk that not all of
American Office Park Properties' profits were so distributed. While we believe
American Office Park Properties qualified as a REIT since 1997, we did not
obtain an opinion of an outside expert at the time of its merger with us.

WE MAY NEED TO BORROW FUNDS TO MEET OUR REIT DISTRIBUTION REQUIREMENTS:
To qualify as a REIT, we must generally distribute to our shareholders 90% of
our taxable income. Our income consists primarily of our share of our operating
partnership's income. We intend to make sufficient distributions to qualify as a
REIT and otherwise avoid corporate tax. However, differences in timing between
income and expenses and the need to make nondeductible expenditures such as
capital improvements and principal payments on debt could force us to borrow
funds to make necessary shareholder distributions.

Since we buy and operate real estate, we are subject to general real estate
- ---------------------------------------------------------------------------
investment and operating risks.
- -------------------------------

SUMMARY OF REAL ESTATE RISKS: We own and operate commercial properties
and are subject to the risks of owning real estate generally and commercial
properties in particular. These risks include:

o 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;

o how prospective tenants perceive the attractiveness, convenience and
safety of our properties;

o our ability to provide adequate management, maintenance and insurance;

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

38



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

o increasing operating costs, including real estate taxes, insurance and
utilities, if these increased costs cannot be passed through to
tenants;

o changes in tax, real estate and zoning laws;

o increase in new developments;

o tenant bankruptcies;

o sublease space; and

o concentration in non-rated private companies.

Certain significant costs, such as mortgage payments, real estate
taxes, insurance and maintenance costs, generally are not reduced even when a
property's rental income is reduced. In addition, environmental and tax laws,
interest rate levels, the availability of financing and other factors may affect
real estate values and property income. Furthermore, the supply of commercial
space fluctuates with market conditions.

If our properties do not generate sufficient income to meet operating
expenses, including any debt service, tenant improvements, leasing commissions
and other capital expenditures, we may have to borrow additional amounts to
cover fixed costs, and we may have to reduce our distributions to shareholders.

During 2001 and 2002, we were affected by the slowdown in economic
activity in the United States in most of our primary markets. These effects were
exacerbated by the terrorist attacks of September 11, 2001 and the related
aftermath. These effects included a decline in occupancy rates and a reduction
in market rates throughout the portfolio, slower than expected lease-up of our
development properties, lower interest rates on invested cash and a rise in
insurance costs. An extended economic slowdown will put additional downward
pressure on occupancies and market rental rates and may lead to pressure for
greater rent concessions, or generous tenant improvement allowances and higher
broker commissions.

WE MAY ENCOUNTER SIGNIFICANT DELAYS IN RELETTING VACANT SPACE,
RESULTING IN LOSSES OF INCOME: When leases expire, we will incur expenses and we
may not be able to release the space on the same terms. Certain leases provide
tenants with the right to terminate early if they pay a fee. Our properties as
of September 30, 2002 generally have lower vacancy rates than the average for
the markets in which they are located, and leases for 24% of our space expire in
2002 or 2003 (leases for 40% of the space occupied by small tenants expire in
such years). While we have estimated our cost of renewing leases that expire in
2002, our estimates could be wrong. If we are unable to release space promptly,
if the terms are significantly less favorable than anticipated or if the costs
are higher, we may have to reduce our distributions to shareholders.

TENANT DEFAULTS AND BANKRUPTCIES MAY REDUCE OUR CASH FLOW AND
DISTRIBUTIONS: We may have difficulty in collecting from tenants in default,
particularly if they declare bankruptcy. This could reduce our cash flow and
distributions to shareholders.

WE MAY BE ADVERSELY AFFECTED BY SIGNIFICANT COMPETITION AMONG
COMMERCIAL PROPERTIES: Many other commercial properties compete with our
properties for tenants and we expect that new properties will be built in our
markets. Also, we compete with other buyers, many of whom are larger than we
are, in seeking to acquire commercial properties. Therefore, we may not be able
to grow as rapidly as we would like.

39



WE MAY BE ADVERSELY AFFECTED IF CASUALTIES TO OUR PROPERTIES ARE NOT
COVERED BY INSURANCE: We carry insurance on our properties that we believe is
comparable to the insurance carried by other operators for similar properties.
However, we could suffer uninsured losses that adversely affect us or even
result in loss of properties. We might still remain liable on any mortgage debt
related to that property.

THE ILLIQUIDITY OF OUR REAL ESTATE INVESTMENTS MAY PREVENT US FROM
ADJUSTING OUR PORTFOLIO TO RESPOND TO MARKET CHANGES: There may be delays and
difficulties in selling real estate. Therefore, we cannot easily change our
portfolio when economic conditions change. Also, tax laws limit a REIT's ability
to sell properties held for less than four years.

WE MAY BE ADVERSELY AFFECTED BY GOVERNMENTAL REGULATION OF OUR
PROPERTIES: Our properties are subject to various federal, state and local
regulatory requirements, such as state and local fire and safety codes. If we
fail to comply with these requirements, governmental authorities could fine us
or courts could award damages against us. We believe our properties comply with
all significant legal requirements. However, these requirements could change in
a way that would reduce our cash flow and ability to make distributions to
shareholders.

WE MAY INCUR SIGNIFICANT ENVIRONMENTAL REMEDIATION COSTS: Under various
federal, state and local environmental laws an owner or operator of real estate
interests may have to clean spills or other releases of hazardous or toxic
substances on or from a property. Certain environmental laws impose liability
whether or not the owner knew of, or was responsible for, the presence of the
hazardous or toxic substances. In some cases, liability may exceed the value of
the property. The presence of toxic substances, or the failure to properly
remedy any resulting contamination, may make it more difficult for the owner or
operators to sell, lease or operate its property or to borrow money using its
property as collateral. Future environmental laws may impose additional material
liabilities on us.

We acquired a property in Beaverton, Oregon ("Creekside Corporate
Park") in May 1998 that was the subject of an environmental investigation
conducted by two current and past owner/operators of an industrial facility on
adjacent property, pursuant to an Consent Decree issued by the Oregon Department
of Environmental Quality ("ODEQ"). There is no evidence that our past or current
use of the Creekside Corporate Park property contributed in any way to the
contamination that is the subject of the current investigation, nor has the ODEQ
alleged any such contribution, and we are not a party to the Consent.

Based on the results of the remedial investigation/feasibility study,
ODEQ has selected a final remedy that would include permanent treatment of
contaminants in the groundwater, including expanded groundwater extraction and
treatment on all parcels of the former industrial property, including portions
of Creekside Corporate Park. The estimated cost of this remedy is $2.8 million
over a 30-year time period. In the event we are ultimately deemed responsible
for any costs relating to this matter, we believe that the party from whom the
property was purchased will be responsible for any expenses or liabilities that
we may incur as a result of this contamination. In addition, we believe we may
have recourse against other potentially responsible parties, including, but not
limited to, one or both of the owner/operators of the adjacent industrial
facility. However, if we are deemed responsible for any expenses related to
removal or remedial actions on the property, and we are not successful in
obtaining reimbursement from one or more third parties, our operations and
financial condition could be harmed.

Based on recent discussions with the ODEQ and other potentially
responsible parties, the Company has estimated its share of the costs of the
remediation at $250,000. The Company has accrued these estimated costs and
included the expense in general and administrative costs.

WE MAY BE AFFECTED BY THE AMERICANS WITH DISABILITIES ACT: The
Americans with Disabilities Act of 1990 requires that access and use by disabled
persons of all public accommodations and commercial properties be facilitated.
Existing commercial properties must be made accessible to disabled persons.
While we have not estimated the cost of complying with this act, we do not
believe the cost will be material.

40



Our ability to control our properties may be adversely affected by ownership
- ----------------------------------------------------------------------------
through partnerships and joint ventures.
- ----------------------------------------

We own most of our properties through our operating partnership. Our
organizational documents do not limit our ability to invest funds with others in
partnerships or joint ventures. During 2001, we entered into a joint venture
arrangement that holds property subject to debt. This type of investment may
present additional risks. For example, our partners may have interests that
differ from ours or that conflict with ours, or our partners may become
bankrupt. In addition, the joint venture may default on its debt, which we have
guaranteed under certain circumstances. We believe this risk is mitigated by the
low level of debt (57% of the cost in the joint venture) and the financial
strength of our joint venture partner.

We can change our business policies and increase our level of debt without
- --------------------------------------------------------------------------
shareholder approval.
- ---------------------

Our board of directors establishes our investment, financing,
distribution and other business policies and may change these policies without
shareholder approval. Our organizational documents do not limit our level of
debt. A change in our policies or an increase in our level of debt could
adversely affect our operations or the price of our common stock.

We can issue additional securities without shareholder approval.
- ----------------------------------------------------------------

We can issue preferred and common stock without shareholder approval.
Holders of preferred stock have priority over holders of common stock, and the
issuance of additional shares of common stock reduces the interest of existing
holders in our company.

Increases in interest rates may adversely affect the market price of our common
- -------------------------------------------------------------------------------
stock.
- ------

One of the factors that influences the market price of our common stock
is the annual rate of distributions that we pay on our common stock, as compared
with interest rates. Interest rates in late 2001 and early 2002 have been at
historically low levels. An increase in interest rates may lead purchasers of
REIT shares to demand higher annual distribution rates, which could adversely
affect the market price of our common stock.

Shares that become available for future sale may adversely affect the market
- ----------------------------------------------------------------------------
price of our common stock.
- --------------------------

Substantial sales of our common stock, or the perception that
substantial sales may occur, could adversely affect the market price of our
common stock. Certain of our shareholders hold significant numbers of shares of
our common stock and, subject to compliance with applicable securities laws,
could sell their shares.

We depend on key personnel.
- ---------------------------

We depend on our executive officers, including Ronald L. Havner, Jr.,
our chief executive officer and Joseph D. Russell, Jr., our president. The loss
of Mr. Havner, Mr. Russell or other executive officers could adversely affect
our operations. We maintain no key person insurance on our executive officers.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

To limit the Company's exposure to market risk, the Company principally
finances its operations and growth with permanent equity capital consisting of
either common or preferred stock. At September 30, 2002, the Company's debt as a
percentage of shareholders' equity (based on book values) was 11.7%.

The Company's market risk sensitive instruments include mortgage notes
payable which totaled $27,720,000 at September 30, 2002. All of the Company's
mortgage notes payable bear interest at fixed rates. See Note 6 of the Notes to
Consolidated Financial Statements for terms, valuations and approximate
principal maturities of the mortgage notes payable as of September 30, 2002.
Based on borrowing rates currently available to the Company, the carrying amount
of debt approximates fair value.

In July, 2002, the partnership entered into an interest rate swap
agreement to reduce the impact of changes in interest rates on a portion of its
floating rate debt. The agreement effectively changes the interest rate exposure
from floating rate to a fixed rate of 4.46%. The Partnership records the
differences paid or received on the interest rate swap in interest expense as
payments are made or received. The Company had an unrealized loss of $974,000
which was included in comprehensive income as of September 30, 2002.

ITEM 4. CONTROLS AND PROCEDURES

(a) Evaluation of disclosure controls and procedures. Based on their
evaluation of the Company's disclosure controls and procedures (as defined in

date within 90 days of the filing date of this Quarterly Report on Form 10-Q,
the Company's chief executive officer and chief financial officer have concluded
that the Company's disclosure controls and procedures are designed to ensure
that information required to be disclosed by the Company in the reports that it
