1.   Organization  and description of business

     PS Business Parks, Inc. ("PSB") was incorporated in the state of California
     in 1990. As of June 30, 2000,  PSB owned an  approximate  74.3% 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, 2000, the Company owned and operated 124 commercial
     properties (approximately 12.3 million net rentable square feet) located in
     10 states.   In addition, the Company managed, on behalf of Public Storage,
     Inc.  ("PSI")   and   affiliated   entities,   38   commercial   properties
     (approximately  1.1 million net rentable square feet).

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,
     2000 are not necessarily indicative of the results that may be expected for
     the year ended  December 31, 2000.  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, 1999.

     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.

     Cash and cash equivalents

     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.  The carrying amount of cash and cash equivalents approximates
     fair value.

     Marketable securities

     The Company owns  approximately  one million  common shares of Pacific Gulf
     Properties  Inc. The investment is 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.  The
     investment  is reflected  on the balance  sheet at fair market  value.  The
     unrealized  gain of  $4,809,000 is excluded from earnings and reported in a
     separate component of shareholders'  equity.  Dividend income is recognized
     when earned.

     Real estate facilities

     Real  estate  facilities  are  recorded  at  cost.  Costs  related  to  the
     renovation or improvement of the properties are  capitalized.  Expenditures
     for  repair  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.

                             PS BUSINESS PARKS, INC.
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  JUNE 30, 2000

     Interest cost and property taxes incurred during the period of construction
     of real estate  facilities are  capitalized.  Construction  in progress and
     developed  projects  include  $1,945,000  and  $1,257,000 of interest costs
     capitalized  at June 30, 2000 and  December  31,  1999,  respectively.  The
     Company capitalized  $688,000 and $410,000 during the six months ended June
     30,  2000 and  1999,  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 $1,024,000  and $874,000 at June 30, 2000 and December 31,
     1999,  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,  2000,  no such  indicators  of
     impairment have been  identified.

     Assets held for disposition are reported at the lower of carrying amount or
     fair value less selling costs.

     Borrowings from and loans to affiliate

     The  Company  borrowed  an  aggregate  of $41.4  million  from PSI and paid
     $371,000 in interest  expense during the period of January 19, 1999 through
     April 30, 1999. The notes bore interest at 5.5% (per annum) and were repaid
     as of April 30, 1999.

     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 revenue 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  pursuant to
     the cost  allocation  and  administrative  service  agreement  between  the
     Company and PSI.

     Acquisition costs

     Internal acquisition costs are expensed as incurred.

     Income taxes

     During 1997, 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 95% 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  1999  and  intends  to  continue  to  meet  such
     requirements for 2000.  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:

     minimum rental revenues  excluding recovery of expenses as of June 30, 2000
     under these leases are as follows:

     In addition to minimum  rental  payments,  tenants pay  reimbursements  for
     their pro rata  share of  specified  operating  expenses,  which  amount to
     $9,175,000  and  $8,216,000  for   the   six  months   ended  June 30, 2000

     and 1999,  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 August  1999,  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, 2002.
     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 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%.  The Company
     had no outstanding balance and $100 million available on its line of credit
     at June 30, 2000 and December 31, 1999.

     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 1.0 and 1.75 to 1.0,  respectively,
     (iii) maintain a minimum total  shareholders'  equity (as defined) and (iv)
     limit  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, 2000.

6.   Mortgage notes payable

     Mortgage notes consist of the following:

7.   Minority interests

     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  applicable
     articles of incorporation,  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 June 30, 2000, there were 7,335,839 OP units owned by minority interests
     (7,305,355 were owned by PSI and affiliated  entities and 30,484 were owned
     by unaffiliated  third parties).  On a fully converted basis,  assuming all
     7,335,839  minority  interest OP units were converted into shares of common
     stock  of  PSB  at  June  30,  2000,  the  minority   interests  would  own
     approximately  24.0% 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
     interests' 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.

                                  JUNE 30, 2000


     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.

     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.

     The Operating Partnership has the right to redeem the preferred units on or
     after the fifth  anniversary  of the 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  majority  of the  holders  of  the  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 entities affiliated with PSI. These facilities,  all located in
     the United  States,  operate  under the "Public  Storage"  or "PS  Business
     Parks" name.

     The property management  contracts provide for compensation of five percent
     of the gross revenue 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,  leasing,
     billing and maintenance personnel.

     The property management contract with PSI is for a seven year term with the
     term being  extended one year each  anniversary.  The  property  management
     contracts with  affiliates of PSI are cancelable by either party upon sixty
     days notice.

9.   Shareholders' equity

     Preferred stock

     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.

     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, 2000, there were no dividends in arrears.

                                       13



                             PS BUSINESS PARKS, INC.
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  JUNE 30, 2000


     Except under certain conditions relating to the Company's  qualification as
     a REIT, the preferred  stock is not redeemable  prior to April 30, 2004. On
     or after April 30, 2004,  the 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 $2,544,000  ($1.156250 per depositary  share) and $862,000
     ($0.391840  per  depositary   share)  in  distributions  to  its  preferred
     shareholders for the six months ended June 30, 2000 and 1999, respectively.

     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.  As of June 30, 2000,
     the Company repurchased 552,600 shares of common stock at an aggregate cost
     of approximately $12.4 million.

     On March 31,  2000,  a holder of common OP units  exercised  its option and
     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  $11,702,000  ($0.50 per common  share) and  $11,819,000
     ($0.50 per common share) in  distributions  to its common  shareholders for
     the six months  ended June 30,  2000 and 1999,  respectively.  Pursuant  to
     restrictions on the Credit  Facility,  distributions  may not exceed 95% of
     funds from operations, as defined.

     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  in years  beginning  after  June 15,  2000.  This
     statement  provides  a  comprehensive  and  consistent   standard  for  the
     recognition  and  measurement of derivatives  and hedging  activities.  The
     Company  is  studying  this  statement  to  determine  its  effect  on  the
     consolidated financial statements and will adopt this statement in the year
     ending December 31, 2001.

11.  Commitments and contingencies

     The Company is subject to the risks inherent in the ownership and operation
     of commercial real estate. These include,  among others, the risks normally
     associated with changes in the general economic climate, trends in the real
     estate industry,  creditworthiness of tenants, competition,  changes in tax
     laws,  interest rate levels,  the  availability  of financing and potential
     liability under environmental and other laws.

                             PS BUSINESS PARKS, INC.
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  JUNE 30, 2000


     Substantially  all of  the  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  be  material  to  the  consolidated  financial
     statements except as discussed below.

     The Company acquired a property in Beaverton,  Oregon ("Creekside Corporate
     Park") in May 1998.  A property  adjacent to  Creekside  Corporate  Park is
     currently     the     subject     of     an     environmental      remedial
     investigation/feasibility  study that is being conducted by the current and
     past  owners of the  property,  pursuant  to an order  issued by the Oregon
     Department of Environmental  Quality ("ODEQ").  As part of that study, ODEQ
     ordered the property owners to sample soil and groundwater on the Company's
     property to determine the nature and extent of contamination resulting from
     past  industrial  operations  at the  property  subject to the  study.  The
     Company,  which is not a party of the Order on Consent,  executed  separate
     Access  Agreements with the property owners to allow access to its property
     to conduct the required  sampling and testing.  The sampling and testing is
     ongoing,   and  preliminary   results  from  one  area  indicate  that  the
     contamination from the property subject to the study may have migrated onto
     a portion of Creekside Corporate Park owned by the Company.

     There  is no  evidence  that  any  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 study, it is likely that removal or remedial  measures will be required
     to address any  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.

     The Company believes that it bears no  responsibility  or liability for the
     contamination.  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.

     On  November  3,  1999,  the  Company  filed an action  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  entities
     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.

     On or about  February 14, 2000,  Mr. Howard and entities  controlled by him
     filed 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-complainants assigned any dollar amount
     in the  cross-complaint  to the claims.  The Company  intends to vigorously
     contest the claims in the cross-complaint.

     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.
     Based on consultation  with counsel,  management  believes that these items
     will  not  have  a  material  adverse  impact  on the  Company's  condensed
     consolidated  financial  position or results of operations.

Such forward-looking  statements involve known and unknown risks,  uncertainties
and other factors.  Actual results could differ  materially from those set forth
in the forward-looking  statements as a result of various factors.  Such factors
include,  but are not limited to a change in economic  conditions in the various
markets  served by the Company's  operations  which would  adversely  affect the
level of demand for rental of  commercial  space and the cost  structure  of the
Company,  general real estate  investment risks,  competition,  risks associated
with  acquisition and development  activities and debt financing,  environmental
matters,  general uninsured losses and seismic  activity.  Readers are cautioned
not to place undue  reliance on these  forward-looking  statements,  which speak
only as of the date hereof.  The Company  undertakes  no  obligation to publicly
release  the result of any  revisions  to these  forward-looking  statements  to
reflect  events  or  circumstances  after  the date  hereof  or to  reflect  the
occurrence of unanticipated events.

     Overview: During 2000 and 1999, the Company focused on increasing cash flow
from its  existing  core  portfolio  of  properties,  expanded  its  presence in
existing   markets  through   strategic   acquisitions   and   developments  and
strengthened  its balance  sheet  primarily  through the  issuance of  preferred
stock/OP units at reasonable  prices.  By maintaining low leverage,  the Company
believes that future growth is facilitated.

     During the first half of 2000, the Company  acquired 178,000 square feet in
Northern California for approximately  $23.3 million.  In addition,  the Company
acquired  21 acres of land in  Texas  for  approximately  $3.7  million  for the
development of two 100,000 square feet flex buildings.

     During 1999, the Company added approximately 1.3 million square feet to its
portfolio  at an  aggregate  cost of  approximately  $103  million.  The Company
acquired  483,000 square feet in Texas for  approximately  $32 million,  405,000
square feet in Northern  Virginia/Maryland market for approximately $41 million,
211,000  square feet in Northern  California for  approximately  $17 million and
200,000 square feet in Arizona for approximately $13 million.

     Results of Operations:  Net income for the three months ended June 30, 2000
was $11,512,000  compared to $10,255,000 for the same period in 1999. Net income
allocable to common shareholders (net income less preferred stock dividends) for
the three months ended June 30, 2000 was $10,240,000  compared to $9,393,000 for
the same  period in 1999.  Net income per  common  share on a diluted  basis was
$0.44 for the three  months  ended June 30, 2000  compared to $0.40 for the same
period in 1999 (based on weighted  average diluted common shares  outstanding of
23,428,000 and  23,716,000,  respectively).  Net income for the six months ended
June 30, 2000 was  $22,255,000  compared to  $19,697,000  for the same period in
1999.  Net income  allocable to common  shareholders  (net income less preferred
stock dividends) for the six months ended June 30, 2000 was $19,711,000 compared
to  $18,835,000  for the same period in 1999.  Net income per common  share on a
diluted basis was $0.84 for the six months ended June 30, 2000 compared to $0.79
for the same period in 1999 (based on weighted  average  diluted  common  shares
outstanding of 23,537,000 and  23,709,000,  respectively).  The increases in net
income and net income per share reflect the  Company's  growth in its asset base
through the acquisition and development of commercial  properties in addition to
increased net operating income from its stabilized base of properties.

     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 107 properties  (10.5 million net rentable
square  feet).  These 107  properties  (herein  referred  to as the "Same  Park"
facilities)  have been owned and  operated  by the  Company  for the  comparable
periods. These properties do not include planned dispositions or properties that
have  been  sold  during  the  year.  The  "Same  Park"   facilities   represent
approximately  86% of the square footage of the Company's  portfolio at June 30,
2000.

     The increases noted above reflect the performance of the Company's existing
markets. The Company experienced growth in rental rates in Southern and Northern
California and Virginia due to a strong economic climate.   In  Southern  Texas,
increases  in operating expenses in excess  of  revenue increases  resulted in a
decrease in NOI. The increases are primarily related to property  tax  expenses.
In  Northern  Texas,  decreases  in  revenue  and  NOI  are primarily related to
decreased expense  recoveries for the three and six months ended June 30, 2000.

     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, 2000, $104,000 in net operating income was recognized from
facility management  operations compared to $93,000 for the same period in 1999.
During the six months ended June 30, 2000,  $202,000 in net operating income was
recognized from facility management operations compared to $184,000 for the same
period in 1999.  Facility  management fees have increased due to the increase in
rental rates of the properties managed by the Company.

     Business Services:     The  Company  recently  hired  a Vice  President  to
focus  on  creating  new  revenue   opportunities for the Company and additional
products  and  services for  our   customers.    Currently   the   Company   has

                                       21



begun  receiving  income  from  construction   management  fees  and  fees  from
telecommunication service providers.  During the three and six months ended June
30,  2000,  $203,000  in net  operating  income was derived  from such  services
compared to none for the same periods in 1999.

     Interest  Income:  Interest  income  reflects  earnings  on cash  balances.
Interest  income was $741,000 for the three months ended June 30, 2000  compared
to $252,000 for the same period in 1999.  Interest income was $2,011,000 for the
six months ended June 30, 2000 compared to $264,000 for the same period in 1999.
The  increase is  attributable  to increased  average  cash  balances and higher
interest  rates.  Average cash balances for the three months ended June 30, 2000
were  approximately  $49.4 million compared to $20.1 million for the same period
in 1999.  Average  cash  balances  for the six months  ended June 30,  2000 were
approximately  $69.9  million  compared to $10.6  million for the same period in
1999.

     Dividend  Income:   Dividend  income  reflects   earnings  from  marketable
securities.  Dividend  income was  $440,000  for the three months ended June 30,
2000  compared  to  $21,000  for the same  period in 1999.  Dividend  income was
$858,000 for the six months ended June 30, 2000 compared to $29,000 for the same
period  in 1999.  The  increase  is  attributable  to  increased  investments in
marketable securities.

     Cost of Operations:  Cost of operations for the three months ended June 30,
2000 was $10,118,000 compared to $8,655,000 for the same period in 1999. Cost of
operations  for the six months ended June 30, 2000 was  $19,670,000  compared to
$17,031,000 for the same period in 1999. Cost of operations for the three months
ended June 30, 2000 consists primarily of property taxes ($3,223,000),  property
maintenance   ($1,793,000),    utilities   ($1,487,000)   and   direct   payroll
($1,409,000). Cost of operations for the six months ended June 30, 2000 consists
primarily of property taxes  ($6,343,000),  property  maintenance  ($3,581,000),
utilities  ($3,099,000)  and direct  payroll  ($2,877,000).  The increase is due
primarily to the growth in the total square  footage of the Company's  portfolio
of  properties.  Cost of operations  as a percentage of rental income  decreased
from 28.0% to 27.8% and from  28.4% to 27.9% for the three and six months  ended
June 30, 2000, respectively,  as a result of economies of scale achieved through
the acquisition and development of properties in existing markets.

     Depreciation  and  Amortization  Expense:   Depreciation  and  amortization
expense  for the three  months  ended June 30, 2000 was  $8,898,000  compared to
$7,314,000 for the same period in 1999.  Depreciation and  amortization  expense
for the six months ended June 30, 2000 was  $17,274,000  compared to $14,047,000
for the  same  period  in  1999.  The  increase  is due to the  acquisition  and
development of real estate facilities during 1999 and 2000.

     General and Administrative Expense:  General and administrative expense was
$981,000 for the three  months ended June 30, 2000  compared to $795,000 for the
same period in 1999. General and  administrative  expense was $1,864,000 for the
six months  ended June 30, 2000  compared to  $1,597,000  for the same period in
1999.  The increase is 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 $117,000 and $95,000 for
the  three  months  ended  June  30,  2000  and  1999,  respectively.  Abandoned
transaction costs were none and $28,000 for the three months ended June 30, 2000
and 1999, respectively.  Acquisition expenses were $248,000 and $185,000 for the
six months  ended June 30, 2000 and 1999,  respectively.  Abandoned  transaction
costs were $7,000 and  $30,000 for the six months  ended June 30, 2000 and 1999,
respectively.

     Interest Expense:  Interest expense was $370,000 for the three months ended
June 30, 2000 compared to $772,000 for the same period in 1999. Interest expense
was $744,000 for the six months ended June 30, 2000 compared to  $1,681,000  for
the same period in 1999. The decrease is attributable to decreased  average debt
balances  during the period.  Interest  expense of  $290,000  and  $225,000  was
capitalized  as  part  of  building  costs   associated  with  properties  under
development during the three months ended June 30, 2000 and 1999,  respectively.
Interest  expense of $688,000 and $410,000 was  capitalized  as part of building
costs associated with properties under  development  during the six months ended
June 30, 2000 and 1999, respectively.

                                       22


     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, 2000 was $6,120,000  ($2,921,000 allocated to preferred unitholders and
$3,199,000  allocated to common  unitholders)  compared to $3,434,000  ($214,000
allocated  to  preferred   unitholders   and  $3,220,000   allocated  to  common
unitholders)  for the same period in 1999.  Minority  interest in income for the
six  months  ended  June  30,  2000 was  $12,031,000  ($5,841,000  allocated  to
preferred  unitholders and $6,190,000 allocated to common unitholders)  compared
to  $6,400,000  ($214,000  allocated to  preferred  unitholders  and  $6,186,000
allocated to common  unitholders)  for the same period in 1999.  The increase in
minority  interest  in income is due  primarily  to the  issuance  of  preferred
operating partnership units in April and September of 1999.

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

     Net cash provided by operating activities for the six months ended June 30,
2000 and 1999 was $55,071,000 and $42,294,000, 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,  debt  service  requirements  and  maintain  the current  level of
distribution to shareholders.

     The Company owns  approximately  one million  common shares of Pacific Gulf
Properties,  Inc.  ("PAG")  representing  an  investment  of  approximately  $20
million.  PAG recently announced the disposition of its industrial portfolio and
the planned  disposition of its  multi-family  portfolio.  PAG expects to make a
cash distribution to shareholders in the fourth quarter of 2000 of up to $26 per
share from the sale proceeds. This would result in net proceeds of approximately
$26 million to the Company or $6 million in excess of our  original  investment.
The  investment  is  currently  reflected  on the  balance  sheet at $25 million
reflecting  the fair market value of the stock at June 30,2000.  The  unrealized
gain is not  reflected  in net  income or FFO.  There is no  assurance  that the
Company will realize the estimated net proceeds.

     The Company sold three  properties  for  approximately  $5.7 million in the
second  quarter of 2000 at a gain of  $97,000.  Two  additional  properties  are
currently  being  marketed.  There  is no  assurance  that  the  sales  will  be
consummated or that the Company will realize the estimated net proceeds.

     The  following  table  summarizes  the  Company's  ability to make  capital
improvements  to maintain  its  facilities  through the use of cash  provided by
operating activities. The remaining cash flow is available to the Company to pay
distributions  to  shareholders,  make  principal  payments  on debt and to make
investments in real estate.

     The  Company's  capital  structure  is  characterized  by a  low  level  of
leverage.  As of June 30, 2000,  the Company had seven fixed rate mortgage notes
payable totaling  $31,362,000 which represented 3.6% of its total capitalization
(based on book value,  including  minority  interests  and debt).  The  weighted
average interest rate for the mortgage notes is 7.59%.

     In August  1999,  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, 2002.  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   Rat     ("LIBOR")    plus   0.75%    to    1.35%       depending    on

                                       24


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%.

     The Company expects to fund its growth  strategies with permanent  capital,
including  issuances  of 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 line of credit.  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 or formation
of joint  ventures.  The Company  targets a leverage ratio of 40% and Funds from
Operations ("FFO") to combined fixed charges and preferred  distributions  ratio
of 3.0 to 1.0.  As of June  30,  2000 and for the six  months  then  ended,  the
leverage ratio was 23% (based on the fair market  capitalization) and the FFO to
fixed charges and preferred distributions coverage ratio was 5.2 to 1.0.

     In April 1999,  the Company  completed a private  placement of preferred OP
units  and a  public  offering  of  depositary  shares  representing  fractional
interest in perpetual  preferred stock resulting in net proceeds  totaling $65.6
million.  The net proceeds from the  placement of preferred OP units,  completed
April 23, 1999 were approximately  $12.5 million.  The preferred OP units have a
preferred  distribution rate of 8 7/8% on a stated value of $12.75 million.  The
preferred OP units have equivalent terms to those of perpetual  preferred stock.
Net proceeds from the public perpetual  preferred stock offering completed April
30, 1999 were $53.1 million.  The preferred  stock has a dividend rate of 9 1/4%
on a stated value of $55 million.  Proceeds from the issuances  were used to pay
off borrowings from an affiliate and a portion was used to repay a mortgage note
payable of  approximately  $11 million.  The  remaining  proceeds  were used for
investment in real estate.

     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.  A portion  of the  proceeds  was used to prepay a  mortgage  note
payable  of  approximately  $8.5  million.  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
and will be used for investment in real estate.

     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 and 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.

                                       25


  FFO for the Company is computed as follows:



                                                                              Six Months Ended June 30,

     Capital  Expenditures:  During the first half of 2000, the Company incurred
$4.7  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 (an aggregate
of $11 - $15 million  based on square  footage at June 30,  2000) and expects to
make  approximately  $1  million  in  renovations  on  a  property  in  Southern
California during the remainder of 2000.


     Distributions: The Company has elected and intends to qualify as a REIT for
federal  income tax  purposes.  As a REIT,  the Company  must meet,  among other
tests,  sources of income, share ownership and certain asset tests. In addition,
the  Company  is not  taxed  on that  portion  of its  taxable  income  which is
distributed to its shareholders provided that at least 95% of its taxable income
is  so  distributed  to  its  shareholders  prior to filing of the Company's tax
return.

     The Board of  Directors  declared a quarterly  dividend of $0.25 per common
share on July 27, 2000. In addition, the Board of Directors declared a quarterly
dividend of  $0.578125  per share on the  depositary  shares  each  representing
1/1000 of a share of 9 1/4% Cumulative  Preferred Stock, Series A. Distributions
are payable on September 30, 2000 to  shareholders  of record as of the close of
business on September 15, 2000.

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, 2000,  the  Company's  debt as a
percentage of shareholders' equity (based on book values) was 5.6%.

     The Company's  market risk  sensitive  instruments  include  mortgage notes
payable which totaled  $31,362,000  at June 30, 2000.  Substantially  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, 2000. Based on
borrowing rates currently available to the Company,  the carrying amount of debt
approximates fair value.
