1.   Organization and description of business

     PS Business Parks, Inc. ("PSB") was incorporated in the state of California
     in 1990.  As of June 30,  2001,  PSB owned an  approximate  75% general and
     limited  partnership  interest in PS Business  Parks,  L.P. (the "Operating
     Partnership"  or "OP").  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 June 30, 2001, the Company owned and operated approximately 13.3 million
     net  rentable  square feet  located in 9 states.  The Company  also managed
     approximately  1.3  million  net  rentable  square feet on behalf of Public
     Storage, Inc. ("PSI"), affiliated entities and a third party owner.

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 (consisting
     of normal recurring  accruals)  necessary for a fair presentation have been
     included.  Operating  results  for the three and six months  ended June 30,
     2001 are not necessarily indicative of the results that may be expected for
     the year ended  December 31, 2001.  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, 2000.

     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.

     Finanical instruments

     The methods and  assumptions  used to estimate  the fair value of financial
     instruments is described below. The Company has estimated the fair value of
     financial  instruments  using available market  information and appropriate
     valuation methodologies.  Considerable judgment 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.

     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.

                            PS BUSINESS PARKS, INC.
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                 JUNE 30, 2001

     Financial assets that are exposed to credit risk consist  primarily of cash
     and cash equivalents and accounts  receivable.  Cash and cash  equivalents,
     which consist  primarily of short-term  investments,  including  commercial
     paper,  are only  invested in entities  with an  investment  grade  rating.
     Accounts  receivable are not a significant  portion of total assets and are
     comprised of a large number of customers.

     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.  The unrealized  loss of $836,000 is excluded
     from earnings and reported in a separate component of shareholders' equity.
     Dividend income is recognized when earned.

     The Company sold its investment in Pacific Gulf  Properties Inc. during the
     six months ended June 30, 2001 and recognized a gain of $15,000.

     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.  Buildings  and
     equipment are  depreciated on the  straight-line  method over the estimated
     useful lives, which are generally 30 and 5 years, respectively.

     Interest cost and property taxes incurred during the period of construction
     of real estate facilities are capitalized. The Company capitalized $898,000
     and $688,000 of interest  expense during the six months ended June 30, 2001
     and 2000, respectively.

     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 $1,326,000 and $1,175,000 at June 30, 2001 and December 31,
     2000, 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.  At June 30,  2001,  no such  indicators  of
     impairment have been identified.

     Loans to affiliate

     The Company loaned an aggregate of $77 million to PSI and received $153,000
     in interest  income  during the period of January 5, 2000 through March 20,
     2000.  The notes bore  interest  at 5.9% (per  annum) and were repaid as of
     March 20, 2000.

     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.  Reimbursements from
     tenants for real estate taxes and other recoverable  operating expenses are
     recognized as revenues in the period the applicable costs are incurred.

     Costs incurred in connection with leasing  (primarily  tenant  improvements
     and leasing  commissions)  are  capitalized  and  amortized  over the lease
     period.

     Property management fees are recognized in the period earned.

     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. Such amounts include amounts
     incurred by PSI on behalf of the Company,  which were subsequently  charged
     to the Company in accordance  with the allocation  methodology set forth in
     the cost  allocation  and  administrative  service  agreement  between  the
     Company and PSI.

     Acquisition costs

     In March 1998,  the Emerging  Issues Task Force  ("EITF") of the  Financial
     Accounting  Standards  Board issued  guidance (the "97-11  Guidance")  with
     respect to Issue No.  97-11,  "Accounting  for Internal  Acquisition  Costs
     Relating to Real Estate Property Acquisitions." The 97-11 Guidance provides
     that a company shall expense internal  pre-acquisition costs (such as costs
     of an  internal  acquisitions  department)  related to the  purchase  of an
     operating   property.   The  Company  does  not  capitalize  such  internal
     pre-acquisition  costs with respect to the  acquisition  of operating  real
     estate facilities.  Accordingly,  the 97-11 Guidance had no impact upon the
     consolidated  financial  statements  and  would  have  had no  impact  upon
     financial  statements  for  periods  prior  to the  issuance  of the  97-11
     Guidance

     Income taxes

     The Company  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, REITs 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 organization and operating requirements to maintain its REIT status
     during 2000 and intends to  continue  to meet such  requirements  for 2001.
     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 weighted  average  common shares
     outstanding.  "Diluted" weighted average common shares outstanding  include
     the  dilutive  effect of stock  options  under the treasury  stock  method.
     "Basic"  weighted average common shares  outstanding  excludes such effect.
     Earnings per share has been calculated as follows:

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 June 30, 2001
     under these leases are as follows:

           2001 (July - December)..............         $   69,310,000
           2002................................            116,525,000
           2003................................             90,012,000
           2004................................             63,635,000
           2005................................             44,540,000
           Thereafter..........................             56,165,000
                                                       -------------------
                                                        $  440,187,000
                                                       ===================

     In addition to minimum  rental  payments,  tenants pay  reimbursements  for
     their pro rata share of specified  operating  expenses,  which  amounted to
     $11,038,000 and $9,175,000 for the six months ended June 30, 2001 and 2000,
     respectively.  These  amounts  are  included  as rental  income and cost of
     operations in the accompanying condensed consolidated statements of income.


5.   Revolving line of credit

     In September  2000, 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 6, 2003.
     The expiration date may be extended by one year on each  anniversary of the
     Credit Facility.  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 1.35% depending on the Company's  credit
     ratings and coverage ratios,  as defined  (currently LIBOR plus 1.00%).  In
     addition,  the Company is required to pay an annual commitment fee of 0.25%
     of the borrowing  limit.  The Company had no  outstanding  balance and $100
     million  available  on its line of credit at June 30, 2001 and December 31,
     2000.

     The  Credit  Facility  requires  the  Company  to  meet  certain  covenants
     including (i)  maintaining a balance sheet  leverage  ratio (as defined) of
     less than 0.50 to 1.00, (ii) maintaining interest and fixed charge coverage
     ratios  (as  defined)  of not  less  than  2.25  to 1.0  and  1.75  to 1.0,
     respectively,  (iii) maintaining a minimum total  shareholders'  equity (as
     defined) and (iv) limiting  distributions  to 95% of funds from operations.
     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 June 30, 2001.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

7.   Minority interest

     Common 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 condensed
     consolidated financial statements.  Minority interest in income consists of
     the  minority  interests'  share of the  condensed  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 Company's 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.

     On  January  12,  2001,  the  Company  redeemed  30,484  common  units from
     unaffiliated third parties for an aggregate cost of $808,000.

     At June 30, 2001, there were 7,305,355 OP units owned by PSI and affiliated
     entities.  On a fully  converted  basis,  assuming all  7,305,355  minority
     interest OP units were converted into shares of common stock of PSB at June
     30, 2001, the minority interest units would convert into  approximately 25%
     of the common shares outstanding.  At the end of each reporting period, PSB
     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 interest's equity in
     the Company.

     Preferred units

     On April 23, 1999, the Operating  Partnership completed a private placement
     of 510,000  preferred units with a preferred  distribution  rate of 8 7/8%.
     The net proceeds from the placement of preferred  units were  approximately
     $12.5 million and were used to repay borrowings from an affiliate.

     On  September  3,  1999,  the  Operating  Partnership  completed  a private
     placement of 3,200,000  preferred units with a preferred  distribution rate
     of 8 3/4%.  The net proceeds  from the  placement  of preferred  units were
     approximately  $78  million and part of the  proceeds  was used to prepay a
     mortgage note payable of approximately $8.5 million.

                                 JUNE 30, 2001

     On September 7 and 23, 1999, the Operating  Partnership  completed  private
     placements of 1,200,000 and 400,000 preferred units,  respectively,  with a
     preferred  distribution rate of 8 7/8%. The net proceeds from the placement
     of preferred units were approximately $39.2 million.

     On July 12, 2000, the Operating  Partnership  completed a private placement
     of 480,000  preferred units with a preferred  distribution  rate of 8 7/8%.
     The net proceeds from the placement of preferred  units were  approximately
     $11.7 million.

     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 Preferred Stock will have the same  distribution  rate and par value as
     the respective  units and will have equivalent  terms to those 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"
     name. In addition, the Operating Partnership manages an office building for
     a third party owner.

     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 extended one year on each anniversary.  The property  management
     contracts with  affiliates of PSI are cancelable by either party upon sixty
     days notice.

     On April 30, 1999, the Company issued  2,200,000  depositary  shares,  each
     representing  1/1,000  of a share  of 9 1/4%  Cumulative  Preferred  Stock,
     Series A. Net proceeds from the public  perpetual  preferred stock offering
     were approximately  $53.1 million and were used to repay borrowings from an
     affiliate and a mortgage  note payable of  approximately  $11 million.  The
     remaining proceeds were used for investment in real estate.

     On May 10, 2001,  the Company  issued  1,840,000  depositary  shares,  each
     representing  1/1,000  of a share  of 9 1/2%  Cumulative  Preferred  Stock,
     Series D in a public offering. On June 18, 2001, the Company issued 800,000
     depositary  shares,  each  representing  1/1,000  of  a  share  of  9  1/2%
     Cumulative Preferred Stock, Series D in a directed placement.  Net proceeds
     from the  offerings  were  approximately  $64.5  million  and were used for
     investment in real estate and general corporate purposes.

     Holders of the  Company's  preferred  stock will not be entitled to vote on
     most matters, except under certain conditions. In the event of a cumulative
     arrearage  equal to six quarterly  dividends,  the holders of the preferred
     stock will have the right to elect two  additional  members to serve on the
     Company's  Board of Directors  until all events of default have been cured.
     At June 30, 2001, there were no dividends in arrears.

     Except under certain conditions relating to the Company's  qualification as
     a REIT, the preferred stock is not redeemable prior to the following dates:
     Series A - April  30,  2004 and  Series D - May 10,  2006.  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  paid  $3,175,000  and  $2,544,000  in  distributions  to  its
     preferred  shareholders  for the six months  ended June 30,  2001 and 2000,

     Common stock

     On March 2, 2000, the Board of Directors  authorized  the  repurchase  from
     time to time of up to 1,000,000 shares of the Company's common stock on the
     open market or in privately negotiated transactions.  On July 27, 2000, the

     the number of common shares  authorized  for  repurchase  from 1,600,000 to
     2,500,000.  Purchases  will be made subject to market  conditions and other

     converted its 107,517 common OP units into an equal number of shares of PSB
     common  stock.  The  conversion  resulted in an  increase in  shareholders'
     equity and a corresponding  decrease in minority  interest of approximately
     $2,531,000,  representing  the  book  value  of the OP units at the time of
     conversion.

     The  Company  paid  $13,214,000  ($0.58 per common  share) and  $11,702,000
     ($0.50 per common share) in  distributions  to its common  shareholders for

     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 gives 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 June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
     "Accounting for Derivative  Instruments and Hedging  Activities,"  which is
     required  to be adopted by the Company on January 1, 2001.  This  statement
     provides a  comprehensive  and consistent  standard for the recognition and
     measurement of derivatives and hedging activities. The Company adopted SFAS
     No. 133 on January 1, 2001.  This  adoption  had no material  impact on the
     Company's consolidated financial statements.

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, are currently the subject
     of an environmental remedial investigation/feasibility study ("RI/FS") that
     is being conducted by two current and past owner/operators of an industrial
     facility on adjacent  property,  pursuant to an order  issued by the Oregon
     Department of Environmental  Quality ("ODEQ").  As part of that study, ODEQ
     ordered the  owner/operators of the industrial  facility to sample soil and
     groundwater on the Company's property to determine the nature and extent of
     contamination  resulting from past  operations at the industrial  facility.
     The  Company,  which  is not a party  to the  Order  on  Consent,  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. The sampling and testing is ongoing; results to date 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.
     Nevertheless,  upon  completion of the RI/FS,  it is likely that removal or
     remedial measures will be required to address contamination detected during
     the current  investigation,  including  any  contamination  on or under the
     Creekside Corporate Park property. Because of the preliminary nature of the
     investigation, the Company cannot predict the outcome of the investigation,
     nor can it estimate the costs of any remediation or removal activities that
     may be required.

     One of the two  owner/operators  that are  conducting the RI/FS pursuant to
     the Order on Consent  recently filed for Chapter 11 bankruptcy  protection.
     It is not clear at this point what impact, if any, this filing will have on
     the  completion  of the RI/FS,  or on any  removal or  remedial  activities
     ordered by the ODEQ. It is possible that the ODEQ could require the Company
     to participate in completing the RI/FS and implementing removal or remedial
     actions that may be required on the Company's property, or to pay a portion
     of the  costs to do so.  In the  event the  Company  is  ultimately  deemed
     responsible  for any costs  relating to this matter,  the Company  believes
     that the party from whom the property was purchased will be responsible for
     any expenses or liabilities  that the Company may incur as a result of this
     contamination.  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.

     On  November  3, 1999,  the  Company  field an action  entitled PS BUSINESS
     PARKS,  INC. V. LARRY HOWARD, ET AL. (Case No. BC219580) in the Los Angeles
     Superior  court  seeking  damages  in  excess  of $1  million,  as  well as
     equitable  relief.  The  complaint  alleges  that Mr.  Howard and  entitles
     controlled  by  him  engaged  in  unfair  trade  practices,  including  (1)
     negotiating kickbacks,  secret rebates and/or unearned discounts from third
     party suppliers for "providing" Company business to those suppliers and (2)
     disrupting the Company's relationship with various suppliers. Mr. Howard is
     not an officer,  employee or authorized  agent of the Company.  On November
     13, 2000, the Court entered a summary  judgement  against the Company.  The
     Company  appealed the Court's  decision,  and on June 4, 2001, the Court of
     Appeal filed its opinion  reversing the grant of summary  judgement against
     the Company, and permitted the Company to amend its complaint to add, among
     other  things,  Mary  Jane  Howard  as  a  defendant.   The  litigation  is
     proceeding.

     On or about  February 14, 2000,  Mr. Howard and entitles  controlled by him
     field a  cross-complaint  against the Company,  Public  Storage,  Inc., and
     several  other   cross-defendants   alleging,   among  other  things,   (1)
     interference  with Mr.  Howard's  contractual  relations with various third
     party suppliers, (2) violation of Title VII of the Civil Rights Act and (3)
     abuse of process.  None of the cross-complaints  assigned any dollar amount
     in  the   cross-complaint  to  the  claims.  All  of  the  claims  in  this
     cross-complaint  against the Company has been  dismissed with the exception
     of one claim for  interference.  The Company intends to vigorously  contest
     this remaining claim in the cross-complaint.

     On November 27, 2000,  Mary Jayne Howard,  a former officer of the Company,
     filed a demand  for  arbitration  with the  American  Arbitration  alleging
     claims against the Company for breach of contract,  gender  discrimination,
     marital  discrimination,  and wrongful  termination based on public policy.
     The demand seeks damages of approximately $2 million. On June 8, 2001, Mrs.
     Howard filed an amended  claim.  The Company  plans to  vigorously  contest
     these claims.

     On  November  27,  2000,  the  Company  filed an action in the Los  Angeles
     Superior  Court  seeking  damages  in  excess  of $1  million,  as  well as
     equitable relief, against Mr. Howard,  entitles controlled by him, and Mrs.
     Howard alleging claims for breach of fiduciary  duty,  fraud,  constructive
     fraud,  aiding and  abetting,  intentional  interference  with  prospective
     economic advantage and unfair competition,  among other things. This action
     was filed for protective  purposes,  and in view of the ruling by the Court
     of Appeal in the Larry Howard case described  above, the Company expects to
     voluntarily dismiss this action without prejudice in the near future.

     On February 2, 2000,  the Company filed an action  against Mary Piper,  its
     former Vice President of operations,  in Riverside  County  Superior Court,
     alleging  claims  for  breach  of  fiduciary  duties,   fraud  and  deceit,
     constructive fraud, negligent misrepresentation, violation of Section 17000
     of the Business and  Professions  Code,  violation of Section  17200 of the
     Business and Professions Code and culpable negligence. The Company's claims
     arose from Ms. Piper's alleged participation in a plan that resulted in the
     payment of  improper  kickbacks  to Larry  Howard,  a former  vendor of the
     Company  and the  husband of Mary  Jayne  Howard,  a former  officer of the
     Company.

     On March 6, 2000,  Ms. Piper filed a  cross-complaint  against the Company,
     alleging that the Company had breached her written  stock option  agreement
     by refusing to allow her to exercise certain options.  Thereafter,  on July
     19,  2001,  Ms.  Piper  obtained  leave to file an amended  cross-complaint
     against the Company,  alleging a number of additional  claims  arising from
     the  termination of her employment on February 2, 2000.  Specifically,  Ms.
     Piper's  cross-complaint  alleged  claims for breach of an oral  employment
     agreement,  wrongful termination based on gender discrimination,  breach of
     the implied covenant of good faith and fair dealing, intentional infliction
     of emotional  distress,  breach of a written contract for stock options and
     age discrimination.  Ms. Piper's amended  cross-complaint seeks $103,773.62
     in alleged  lost  profits  with  respect to the stock  options,  additional
     compensatory  damages  according  to proof,  attorneys'  fees,  prejudgment
     interest  and  punitive  damages.  No trial date has been set.  The Company
     denies Ms.  Piper's  allegations  and intends to  vigorously  contest these
     claims.

     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 these  items  will not have a  material  adverse
     impact  on the  Company's  condensed  consolidated  financial  position  or
     results of operations.

ITEM 2.           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                  AND RESULTS OF OPERATIONS

         Forward-Looking   Statements:   Forward-looking   statements  are  made
throughout this Quarterly Report on Form 10-Q. For this purpose,  any statements
contained  herein that are not statements of historical fact may be deemed to be

differ  materially  from those  indicated  by such  forward-looking  statements,
including  those detailed under the heading "Item 2A. Risk Factors." In light of
the  significant  uncertainties  inherent  in  the  forward-looking   statements
included herein,  the inclusion of such information  should not be regarded as a

statements to reflect actual results, changes in assumptions or changes in other
factors affecting such forward-looking statements.

         Overview:  During  2000 and the six  months  ended June 30,  2001,  the
Company  focused on  increasing  cash flow from its existing  core  portfolio of
properties,  expanding  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  maintained low
debt and overall leverage levels including  preferred  stock/units to facilitate
future growth.

         During the six months  ended June 30,  2001,  the Company  expanded its
presence in Northern  Viriginia.  The Company acquired 12 buildings known as the
Prosperity  Business  Campus  in  Fairfax  County,  Virginia  at a cost of $88.4
million.  The acquisition was funded with the Company's existing cash, including
proceeds from the issuance of  depositary  shares.  The 12 buildings  consist of
four office  buildings  (355,000  square  feet) and eight  flex-space  buildings
(302,000  square  feet).  The Company plans to continue to build its presence in
existing markets by acquiring high quality  facilities in selected markets.  The
Company  targets  properties with below market rents which offer the Company the
ability  to raise  rents to market as leases  expire in  addition  to  achieving
economies of scale resulting in more efficient operations.

         During 2000, the Company added approximately 0.8 million square feet to
its  portfolio  at  an  aggregate  cost  of  approximately  $82  million.  These
acquisitions increased the Company's presence in its existing markets, which the
Company believes have the  characteristics  necessary for long-term growth.  The
Company  acquired  454,000  square feet in Southern  California for $40 million,
178,000 square feet in Northern California for $23 million,  210,000 square feet
in Northern  Virginia for approximately  $19 million.  In addition,  the Company
completed  development on a property  totaling  22,000 square feet in Oregon for
approximately  $3 million.  The Company  also sold five  properties  aggregating
627,000 square feet for approximately $23.8 million in non-core markets.

         Results of  Operations:  Net income for the three months ended June 30,
2001 was  $12,830,000  compared to $11,512,000  for the same period in 2000. Net
income  allocable  to common  shareholders  (net  income  less  preferred  stock
dividends) for the three months ended June 30, 2001 was $10,927,000  compared to
$10,240,000  for the same  period in 2000.  Net  income  per  common  share on a
diluted  basis was $0.48 for the three  months  ended June 30, 2001  compared to
$0.44 for the same  period in 2000  (based on weighted  average  diluted  common
shares outstanding of 22,679,000 and 23,428,000,  respectively).  Net income for
the six months ended June 30, 2001 was  $24,295,000  compared to $22,255,000 for
the same period in 2000. Net income allocable to common shareholders (net income
less  preferred  stock  dividends)  for the six months  ended June 30,  2001 was
$21,120,000  compared to $19,711,000 for the same period in 2000. Net income per
common share on a diluted basis was $0.92 for the six months ended June 30, 2001
compared to $0.84 for the same period in 2000 (based on weighted average diluted
common shares outstanding of 22,885,000 and 23,537,000, respectively).

         Supplemental  Property  Data  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  (11.5 million net
rentable square feet).  These  properties in which the Company  currently has an
ownership  interest (herein referred to as the "Same Park" facilities) have been
owned and operated by the Company for the comparable periods. The square footage
has  been  reduced  since  the end of the  first  quarter  of 2001  for  planned
dispositions.  The "Same Park"  facilities  represent  approximately  86% of the
square footage of the Company's portfolio at June 30, 2001.

         The  following  table   summarizes  the   pre-depreciation   historical
operating  results  of the "Same  Park"  facilities  excluding  the  effects  of
accounting for rental income on a straight-line basis.

     Northern  California and Oregon continue to benefit from the expirations of
leases with below market rents.  Southern Texas revenues increased in comparison
to 2000  primarily  due to  increased  occupancy  and rental rate  increases  at
certain Austin  facilities.  Other markets grew to a lesser extent  resulting in
revenue and NOI increases in most of our markets.

         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  June  30,  2001,  $131,000  in net  operating  income  was
recognized from facility management operations compared to $104,000 for the same
period in 2000.  During the six  months  ended June 30,  2001,  $256,000  in net
operating income was recognized from facility management  operations compared to
$202,000 for the same period in 2000.  Facility  management  fees have increased
due to the increase in rental rates of the properties managed by the Company and
an additional property brought under management during 2000.

         Business Services:  Business services include  construction  management
fees and fees from telecommunication service providers.  During the three months
ended June 30,  2001,  the  Company  generated a net  operating  loss of $53,000
compared to net operating income of $203,000 for the same period in 2000. During
the six months ended June 30, 2001,  the Company  generated a net operating loss
of $80,000  compared to net operating  income of $203,000 for the same period in
2000.

         Interest  Income:  Interest income reflects  earnings on cash balances.
Interest  income was $553,000 for the three months ended June 30, 2001  compared
to $741,000 for the same period in 2000.  Interest income was $1,313,000 for the
six months  ended June 30, 2001  compared to  $2,011,000  for the same period in
2000. The decreases are attributable to lower average cash balances and interest
rates.  Average  cash  balances  for the three  months  ended June 30, 2001 were
approximately  $51 million  compared to $49 million for the same period in 2000.
Average cash balances for the six months ended June 30, 2001 were  approximately
$55 million compared to $70 million for the same period in 2000.

         Dividend  Income:  Dividend  income  reflects  dividends  received from
marketable  securities.  Dividend  income was $4,000 for the three  months ended
June 30, 2001 compared to $440,000 for the same period in 2000.  Dividend income
was $8,000 for the six months  ended June 30, 2001  compared to $858,000 for the
same  period  in 2000.  No  dividend  income  was  received  from  Pacific  Gulf
Properties, Inc. during the three and six months ended June 30, 2001.

         Cost of Operations:  Cost of operations for the three months ended June
30, 2001 was  $10,475,000  compared to $10,118,000  for the same period in 2000.
Cost of  operations  for the six  months  ended  June 30,  2001 was  $20,846,000
compared to  $19,670,000  for the same  period in 2000.  The  increases  are due
primarily to increased utilities,  repairs and maintenance and payroll costs and
the growth in the total square footage of the Company's portfolio of properties.
Cost of operations for the three months ended June 30, 2001 consisted  primarily
of property taxes ($3,487,000),  property  maintenance  ($1,947,000),  utilities
($1,605,000)  and direct  payroll  ($1,557,000).  Cost of operations for the six
months ended June 30, 2001 consisted  primarily of property taxes  ($6,860,000),
property  maintenance  ($4,016,000),  utilities  ($3,542,000) and direct payroll
($3,267,000). Cost of operations as a percentage of rental income decreased from
27.8% to 26.0% and from 27.9% to 26.5% for the three and six  months  ended June
30, 2001,  respectively,  as a result of economies of scale achieved through the
acquisition and development of properties in core markets and the disposition of
properties  outside  of the  Company's  core  markets  in  addition  to  revenue
increases  in  excess  of  expense   increases  at  the  Company's  "Same  Park"
facilities.

         Depreciation  and Amortization  Expense:  Depreciation and amortization
expense  for the three  months  ended June 30, 2001 was  $9,733,000  compared to
$8,898,000 for the same period in 2000.  Depreciation and  amortization  expense
for the six months ended June 30, 2001 was  $19,379,000  compared to $17,274,000
for the same period in 2000.  The increase is primarily  due to the  acquisition
and development of real estate facilities during 2000 and 2001.

                                       24



         General and Administrative Expense:  General and administrative expense
was $992,000  for the three months ended June 30, 2001  compared to $981,000 for
the same period in 2000. General and  administrative  expense was $2,120,000 for
the six months ended June 30, 2001 compared to $1,864,000 for the same period in
2000.  The increases are due primarily to the increased  size and  activities of
the Company.  Included in general and administrative costs are acquisition costs
and abandoned transaction costs. Acquisition expenses were $114,000 and $117,000
for the three  months  ended  June 30,  2001 and 2000,  respectively.  Abandoned
transaction  costs were $5,000 and none for the three months ended June 30, 2001
and 2000, respectively.  Acquisition expenses were $317,000 and $248,000 for the
six months  ended June 30, 2001 and 2000,  respectively.  Abandoned  transaction
costs were  $7,000 and $7,000 for the six months  ended June 30,  2001 and 2000,
respectively.

         Interest  Expense:  Interest  expense was $157,000 for the three months
ended June 30, 2001  compared to $370,000 for the same period in 2000.  Interest
expense was $394,000 for the six months ended June 30, 2001 compared to $744,000
for the same period in 2000.  The  decreases are  attributable  to lower average
debt balances  during the period and greater  capitalized  interest in 2001 as a
result of greater  construction  in progress.  Interest  expense of $486,000 and
$290,000 was  capitalized as part of building costs  associated  with properties
under  development  during  the  three  months  ended  June 30,  2001 and  2000,
respectively.  Interest expense of $898,000 and $688,000 was capitalized as part
of building costs  associated with properties under  development  during the six
months ended June 30, 2001 and 2000, respectively.

         Gain on Investment in Pacific Gulf Properties Inc. ("PAG"): The Company
sold its  investment  in PAG  during  the six  months  ended  June 30,  2001 and
recognized a gain of $15,000.

         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 for the three  months ended
June 30, 2001 was $6,729,000  ($3,186,000 allocated to preferred unitholders and
$3,543,000 allocated to common unitholders)  compared to $6,120,000  ($2,921,000
allocated  to  preferred   unitholders   and  $3,199,000   allocated  to  common
unitholders)  for the same period in 2000.  Minority  interest in income for the
six  months  ended  June  30,  2001 was  $13,152,000  ($6,373,000  allocated  to
preferred  unitholders and $6,779,000 allocated to common unitholders)  compared
to $12,031,000  ($5,841,000  allocated to preferred  unitholders  and $6,190,000
allocated to common  unitholders)  for the same period in 2000. The increases in
minority  interest in income are due  primarily  to the  issuance  of  preferred
operating  partnership  units during 2000 and higher  earnings at the  operating
partnership  level,  partially  offset by a conversion  of units to common stock
during 2000.

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

         Net cash provided by operating activities for the six months ended June
30, 2001 and 2000 was  $59,761,000  and  $55,071,000,  respectively.  Management
believes that its 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 low level of
leverage.  As of June 30, 2001,  the Company had seven fixed rate mortgage notes
payable totaling $30,563,000, which represented 3.2% of its total capitalization
(based on book  value,  including  minority  interest  and debt).  The  weighted
average interest rate for the mortgage notes is 7.56%.

         The  Company  expects  to fund its  growth  strategies  with  permanent
capital,  including  issuances  of common  and  preferred  stock,  and  retained
internally  generated 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 unsecured line of
credit (the "Credit  Facility").  The Company intends to repay amounts  borrowed
under the Credit Facility from  undistributed cash flow or, as market conditions
permit  and as  determined  to be  advantageous,  from  the  public  or  private
placement of  preferred  and common  stock/OP  units of the Company or Operating
Partnership or the formation of joint  ventures.  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 Funds  from  Operations
("FFO") to combined  fixed charges and preferred  distributions  ratio of 3.0 to
1.0. As of June 30, 2001 and for the six months then ended,  the leverage  ratio
was 26% and the FFO to fixed charges and preferred  distributions coverage ratio
was 5.2 to 1.0.

                                       26


         On May 10, 2001, the Company issued 1,840,000  depositary shares,  each
representing  1/1,000 of a share of 9 1/2% Cumulative  Preferred Stock, Series D
in a public  offering.  On June 18, 2001, the Company issued 800,000  depositary
shares,  each  representing  1/1,000 of a share of 9 1/2%  Cumulative  Preferred
Stock,  Series D in a directed  placement.  Net proceeds from the offerings were
approximately  $64.5  million  and were used for  investment  in real estate and
general corporate purposes.

         In September 2000, 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 6, 2003. The  expiration  date may be extended by one
year on  each  anniversary  of the  Credit  Facility.  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 1.35% depending
on the Company's credit ratings and coverage ratios, as defined (currently LIBOR
plus 1.00%).  In addition,  the Company is required to pay an annual  commitment
fee of 0.25% of the  borrowing  limit.  As of June 30, 2001,  the Company had no
balance outstanding on the Credit Facility.

         Funds  from  Operations:  FFO is  defined as net  income,  computed  in
accordance with accounting  principles  generally accepted in the United States,
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 accounting  principles  generally accepted in the United States. FFO does not
take  into  consideration  scheduled  principal  payments  on  debt  or  capital
improvements.  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 pay  distributions or debt
principal  payments.  Also, FFO as computed and disclosed by the Company may not
be comparable to FFO computed and disclosed by other REITs.

         FFO for the Company is computed as follows:

         Capital  Expenditures:  During the six months ended June 30, 2001,  the
Company  incurred  $3.8  million in  maintenance  capital  expenditures,  tenant
improvements and capitalized lease commissions. On a recurring annual basis, the
Company expects $0.90 to $1.20 per square foot in recurring capital expenditures
($12 - $16 million based on square footage at June 30, 2001).  In addition,  the
Company  expects to make $1.0 million in  renovations  on a property in Southern
California during the second half of 2001.

                                       27


         Stock Repurchase:  On May 8, 2001, the Board of Directors increased the
number  of  common  shares  authorized  to  be  repurchased  from  1,600,000  to
2,500,000.  The shares may be repurchased  periodically on the open market or in
privately  negotiated  transactions.  The Company  repurchased 647,900 shares of
common stock at an aggregate cost of approximately  $17.4 million during the six
months ended June 30, 2001.

         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.

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: At June 30, 2001, PSI owned
24% of the  outstanding  shares of our common stock (43% upon  conversion of its
interest in our  operating  partnership).  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. In addition, PSI's ownership may
make it more difficult for another party to take over our company  without PSI's
approval.

        PSI has a voting  agreement with another large  shareholder:  PSI and an
institutional  shareholder  owning 27% of our common  stock as of June 30,  2001
have both agreed to vote their shares to support specified nominees to our board
of directors until the voting  agreement  expires,  which is not before December
2001.  This voting  agreement  may further  increase  PSI's  influence  over our
company.

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. Our articles of incorporation also contain other provisions
that could have the same effect. We can also cause our operating  partnership to
issue additional interests for cash or in exchange for property.

         The  partnership  agreeement 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.  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  interests of our  shareholders.  Also, as general
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.

                                       29



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

         Before 2007,  we may not sell 13  specified  properties  without  PSI's
approval. Since PSI would be taxed on a sale of these properties,  the interests
of PSI and our shareholders may differ as to the best time to sell.

Certain institutional investors have special rights.
- ----------------------------------------------------

         Certain  institutional  investors  have  rights,  such as the  right to
approve nominees to our board of directors, the right to purchase our securities
in certain  circumstances and the right to require registration of their shares,
not available to our public shareholders.

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.  To continue to qualify as a
REIT, we need to satisfy certain  requirements under the federal income tax laws
relating to our income,  assets,  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 profits before the end of 1996. 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;

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

                                       30


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

     o    changes in tax, real estate and zoning laws.

         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.

         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.  While we have
estimated our cost of renewing  leases that expire in 2001, 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  bankruptcies.  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 us, in
seeking to acquire commercial properties.  Therefore, we may not be able to grow
as rapidly as we would like.

         We may be  adversely  affected  if  losses  on 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 the  property.  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 many be adversely  affected by changes in laws:  Increases in income
and  service  taxes  may  reduce  our cash  flow and  ability  to make  expected
distributions  to our  shareholders.  Our properties are also 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

                                       31


operator  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 in May 1998  known as
Creekside  Corporate  Park. A portion of Creekside  Corporate  Park,  as well as
properties adjacent to Creekside Corporate Park, are currently the subject of an
environmental remedial  investigation/feasibility study, or RI/FS, that is being
conducted by two current and past  owner/operators of an industrial  facility on
adjacent  property,  pursuant to a consent order issued by the Oregon Department
of  Environmental  Quality,  or ODEQ.  As part of that study,  ODEQ  ordered the
owner/operators of the industrial facility to sample soil and groundwater on our
property to determine the nature and extent of contamination resulting from past
operations at the industrial facility. Because we are not a party to the consent
order, we executed  separate  agreements with the two  owner/operators  to allow
them access to  portions of  Creekside  Corporate  Park to conduct the  required
sampling  and  testing.  The  sampling  and testing is ongoing;  results to date
indicate that the contamination  from the industrial  facility has migrated onto
portions of Creekside Corporate Park owned by us.

         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.  Nevertheless,  upon  completion  of the
RI/FS,  it is likely  that  removal or  remedial  measures  will be  required to
address contamination detected during the current  investigation,  including any
contamination on or under the Creekside Corporate Park property.  Because of the
preliminary  nature of the  investigation,  we cannot predict the outcome of the
investigation,  nor can we  estimate  the costs of any  remediation  or  removal
activities that may be required.

         One of the two  owner/operators  that are conducting the RI/FS pursuant
to the consent order recently filed for Chapter 11 bankruptcy protection.  It is
not clear at this  point  what  impact,  if any,  this  filing  will have on the
completion of the RI/FS, or on any removal or remedial activities ordered by the
ODEQ. It is possible that the ODEQ could require us to participate in completing
the RI/FS and  implementing  removal or remedial actions that may be required on
our  property,  or to pay a  portion  of the costs to do so. 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  that 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.

         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.

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.  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.

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 our 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.

                                       32


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.  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  president.  The  loss of Mr.  Havner  could
adversely affect our operations. We maintain no key person insurance on him.

                                       33



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 June 30, 2001,  the  Company's  debt as a
percentage of shareholders' equity (based on book values) was 4.9%.

         The Company's market risk sensitive  instruments include mortgage notes
payable  which  totaled  $30,563,000  at June  30,  2001.  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 June 30, 2001. Based on
borrowing rates currently available to the Company,  the carrying amount of debt
approximates fair value.

PART II. OTHER INFORMATION

ITEM 1.           LEGAL PROCEEDINGS

         On February 2, 2000,  the Company  filed an action  against Mary Piper,
its former Vice President of operations,  in Riverside  County  Superior  Court,
alleging claims for breach of fiduciary duties,  fraud and deceit,  constructive
fraud, negligent  misrepresentation,  violation of Section 17000 of the Business
and Professions Code, violation of Section 17200 of the Business and Professions
Code and  culpable  negligence.  The  Company's  claims  arose from Ms.  Piper's
alleged  participation  in a plan  that  resulted  in the  payment  of  improper
kickbacks  to Larry  Howard,  a former  vendor of the Company and the husband of
Mary Jayne Howard, a former officer of the Company.

         On March  6,  2000,  Ms.  Piper  filed a  cross-complaint  against  the
Company,  alleging  that the  Company had  breached  her  written  stock  option
agreement by refusing to allow her to exercise certain options.  Thereafter,  on
July 19,  2001,  Ms.  Piper  obtained  leave to file an amended  cross-complaint
against the Company,  alleging a number of  additional  claims  arising from the
termination  of her  employment on February 2, 2000.  Specifically,  Ms. Piper's
cross-complaint  alleged  claims  for  breach of an oral  employment  agreement,
wrongful  termination  based on gender  discrimination,  breach  of the  implied
covenant of good faith and fair  dealing,  intentional  infliction  of emotional
distress, breach of a written contract for stock options and age discrimination.
Ms. Piper's amended  cross-complaint  seeks  $103,773.62 in alleged lost profits
with respect to the stock options,  additional compensatory damages according to
proof, attorneys' fees, prejudgment interest and punitive damages. No trial date
has been set.  The  Company  denies  Ms.  Piper's  allegations  and  intends  to
vigorously contest these claims.
