                     REAL ESTATE PURCHASE AND SALE AGREEMENT

      THIS REAL ESTATE PURCHASE AND SALE AGREEMENT (the "Agreement"), is made as
of the 9th day of August,  2005 (the "Agreement  Date") by and between SCHNITZER
INVESTMENT  CORP.,  an  Oregon  corporation  ("Seller"),  and  BARRETT  BUSINESS
SERVICES, INC., a Maryland corporation ("Buyer").

                                R E C I T A L S:

      WHEREAS,  Seller desires to sell certain improved real property along with
certain related personal and intangible property,  and Buyer desires to purchase
said real,  personal and  intangible  property on the terms and  conditions  set
forth herein;

      NOW,  THEREFORE,   in  consideration  of  the  foregoing  and  the  mutual
undertakings  set forth  herein,  and for good and valuable  consideration,  the
receipt and  sufficiency of which is hereby  acknowledged,  the Buyer and Seller
hereby agree as follows:

      1. Property  Included in Sale.  Seller hereby agrees to sell and convey to
Buyer, and Buyer hereby agrees to purchase from Seller, the following:

      (a) the improved real property  commonly  known as: 8100 NE Parkway Drive,
Vancouver, Washington, and legally described on Exhibit A (the "Real Property");

      (b) Seller's interest in all rights,  privileges and easements appurtenant
to the Real Property,  including, without limitation, all minerals, oil, gas and
other  hydrocarbon  substances as well as all  development  rights,  air rights,
water,  water rights (and water stock, if any) relating to the Real Property and
any easements,  rights-of-way or other appurtenances used in connection with the
beneficial use and enjoyment of the Real Property;

      (c) Seller's interest in all improvements and fixtures located on the Real
Property,  including all buildings and structures  presently located on the Real
Property,  all apparatus,  equipment and appliances  used in connection with the
operation  or  occupancy  of  the  Real  Property,   such  as  heating  and  air
conditioning  systems  and  facilities  used to provide  any  utility  services,
refrigeration,  ventilation,  garbage disposal,  recreation or other services on
the  Real  Property  (all  of  which  are   collectively   referred  to  as  the
"Improvements");

      (d) Seller's  interest in any  tangible or  intangible  personal  property
owned  by  Seller  and  used in the  ownership,  use and  operation  of the Real
Property and Improvements,  (excepting those including the name "Schnitzer") now
used in  connection  with the Real Property (the  "Personal  Property")  and any
contract or lease rights, agreements, utility contracts, maintenance and service
contracts or other rights  relating to the  ownership,  use and operation of the
Real Property.


                                       1



      (e) All of the items  referred to in  subparagraphs  (a), (b), (c) and (d)
above are hereinafter collectively referred to as the "Property."

      2. Purchase Price/Remedies.

      (a) The total purchase  price (the  "Purchase  Price") for the Property is
Eight Million Eight Hundred Fifty Thousand and No/100  Dollars  ($8,850,000.00).
The Purchase Price is payable by wire transfer of immediately available funds in
U.S. dollars by the federal bank wire transfer system  deliverable no later than
12:00 p.m. Pacific on the Closing Date (as defined herein) to Pacific  Northwest
Title of Oregon, Inc., 111 SW Columbia, Ste. 1280, Portland, Oregon 97201, Attn:
Yvonne Clifford (telephone: (503) 350-5040) (the "Escrow Agent").

      (b)  Within two (2)  business  days of the  Agreement  Date,  Buyer  shall
deposit into escrow with the Escrow Agent a promissory note in the amount of Two
Hundred Thousand and No/100 Dollars ($200,000.00) as earnest money (the "Earnest
Money Note"). If Buyer elects to proceed with the transaction,  then upon giving
its Approval  Notice (as defined in Section 4(d) below),  Buyer will convert the
Earnest  Money Note to cash and  deposit  the same into  escrow  with the Escrow
Agent (the  "Deposit").  Any interest  earned on the Deposit shall be considered
part of the Deposit. Except as otherwise provided in this Agreement, the Deposit
shall  be held by the  Escrow  Agent in a  federally  insured  interest  bearing
account and applied against the cash portion of the Purchase Price at Closing.

      (c) IF BUYER FAILS,  WITHOUT LEGAL EXCUSE, TO COMPLETE THE PURCHASE OF THE
PROPERTY PURSUANT TO THIS AGREEMENT,  THE DEPOSIT (INCLUDING ALL INTEREST EARNED
FROM THE  INVESTMENT  THEREOF)  SHALL BE PAID TO  AND/OR  RETAINED  BY SELLER AS
LIQUIDATED DAMAGES.  THE PARTIES ACKNOWLEDGE THAT SELLER'S ACTUAL DAMAGES IN THE
EVENT  THAT  THE  SALE  IS NOT  CONSUMMATED  WOULD  BE  EXTREMELY  DIFFICULT  OR
IMPRACTICABLE  TO DETERMINE.  THEREFORE,  BY SEPARATELY  EXECUTING  THIS SECTION
BELOW,  THE PARTIES  ACKNOWLEDGE  THAT THE DEPOSIT HAS BEEN AGREED  UPON,  AFTER
NEGOTIATION,  AS THE  PARTIES'  REASONABLE  ESTIMATE OF SELLER'S  DAMAGES AND AS
SELLER'S  EXCLUSIVE  REMEDY  AGAINST BUYER IN THE EVENT OF A BREACH BY BUYER AND
THE CLOSING DOES NOT OCCUR AND AS SELLER'S  SOLE AND  EXCLUSIVE  REMEDY  AGAINST
BUYER  ARISING FROM SUCH DEFAULT.  NOTWITHSTANDING  THE  FOREGOING,  IN NO EVENT
SHALL THIS PARAGRAPH 2(c) LIMIT THE DAMAGES  RECOVERABLE BY EITHER PARTY AGAINST
THE OTHER PARTY DUE TO THE OTHER PARTY'S  OBLIGATION TO INDEMNIFY  SUCH PARTY IN
ACCORDANCE WITH THIS AGREEMENT. MOREOVER, THIS SECTION SHALL NOT PRECLUDE SELLER
FROM RECOVERING ADDITIONAL DAMAGES FROM BUYER PURSUANT TO PARAGRAPH 9.

                                       2




      (d) In the event that Seller shall be in default  hereunder,  Buyer's sole
and  exclusive  remedy shall be either:  (i) deliver a written  notice to Seller
within  three (3)  business  days of  learning  of such  default,  stating  with
particularity the alleged default of Seller and the action required by Seller to
cure such default, and stating Buyer's intent to terminate this Agreement if the
default is not cured,  whereupon Seller shall have seven (7) business days after
receipt of such written  notice in which to cure the alleged  default to Buyer's
reasonable  satisfaction  and to thereby  prevent  termination of this Agreement
(and the Closing  Date shall be  delayed,  if  necessary,  until the end of such
seven (7) business day period), or in the event such default is not cured within
such seven (7) business day period,  terminate  this Agreement by written notice
to Seller and the Escrow  Agent,  in which case the Deposit shall be returned to
Buyer;  or (ii) if  Seller's  default  results  from  its  failure  to  transfer
possession  and title to the  Property  to Buyer at  Closing,  enforce  specific
performance;  provided,  however,  that if specific  performance is not obtained
within thirty (30) days of the scheduled Closing Date, Seller shall be liable to
Buyer for Buyer's  actual out-of pocket costs and expenses  (including,  without
limitation  reasonable  attorneys'  fees and costs)  incurred in connection with
this Agreement or as a result of Seller's default  hereunder.  In no event under
(i) or (ii) above shall Seller be liable to Buyer for any punitive, speculative,
consequential or other damages.

      3. Title to the Property. At the Closing, Seller shall convey to Buyer and
Buyer  shall  accept  marketable  and  insurable  fee  simple  title to the Real
Property,  all rights,  privileges and easements appurtenant thereto, and to the
Improvements,  by duly executed and acknowledged  Statutory Warranty Deed in the
form attached as Exhibit B (the "Deed").  Evidence of delivery of marketable and
insurable  fee simple  title  shall be the  issuance of a current  ALTA  Owner's
Extended  Coverage  Policy  of  Title  Insurance  (Form  1970-B)  containing  no
exceptions to coverage other than the Permitted  Exceptions (the "Title Policy")
by Pacific  Northwest  Title of  Oregon,  Inc.  (the  "Title  Company"),  in the
allocable  amount of the Purchase  Price,  insuring fee simple title to the Real
Property, Improvements, and appurtenant rights, privileges and easements, in the
Buyer.

      4. Buyer's Due  Diligence.  On or before the date five (5)  business  days
after  mutual  execution of this  Agreement  by Seller and Buyer (the  "Delivery
Date"), Seller shall deliver the following documents and instruments relating to
the Property, all to the extent the same exist and are in Seller's possession or
control (collectively "Seller Information"):  (a) leases or occupancy agreements
for any portion of the Property  (including any parking area) and any amendments
or other agreements relating to the leases (collectively the "Leases");  (b) any
environmental  reports  in  Seller's  possession  or  control  relating  to  the
Property;  (c) operating statements for the Property for the calendar years 2003
and 2004 to date;  (d) current rent roll;  (e) any existing  surveys in Seller's
possession or control;  (f) occupancy  permits and certificates of occupancy for
the  Improvements;  (g) service and maintenance  contracts which would remain in
effect after  Closing;  (h) the most recent tax bills for the Property;  and (i)
pleadings,  correspondence  and other  documentation  relating to any litigation
affecting the Property.

                                       3




      Buyer shall be allowed to conduct the  following  due  diligence  prior to
purchasing the Property ("Buyer's Due Diligence Review"):

      (a)  Buyer's  review  of title  to the  Property  as shown on an  existing
preliminary commitment for an ALTA (Form 1970-B) Owner's Extended Coverage title
insurance  policy  and  copies  of all  recorded  documents  referenced  therein
(collectively, the "Title Report") from the Title Company issued with respect to
the Real  Property  and a current  as-built  ALTA/ACSM  land survey  showing the
location of all improvements and recorded  easements and other matters affecting
title to the Property and certified to Buyer and Title  Company (the  "Survey"),
all of which shall be  delivered by Seller with the other Due  Diligence  Items.
Within ten (10)  business  days after  Buyer's  receipt of the Title  Report and
Survey (the "Title Documents"), Buyer may approve or disapprove (in its sole and
absolute  discretion) the Title Documents for the Property by delivering written
notice to Seller ("Buyer's Title Notice") specifying each title defect or matter
for which Buyer is requesting a cure by Seller  ("Title  Defect") and each Title
Company  requirement  ("Title  Requirement") which Buyer is requesting Seller to
satisfy in order for the Title  Policy to be issued for the Property at Closing.
Buyer's failure to deliver Buyer's Title Notice to Seller within the time period
specified  above shall be a conclusive  presumption  that Buyer has approved the
Title Documents and this Agreement shall remain in full force and effect. Within
five (5) business days after Buyer's Title Notice is given, Seller shall deliver
to Buyer written notice  ("Seller's  Title Notice") of those Title Defects which
Seller covenants and agrees to either eliminate or cure to Buyer's  satisfaction
by the Closing Date and those Title  Requirements which Seller agrees to satisfy
by the Closing Date.  Seller's failure to deliver Seller's Title Notice to Buyer
within the time period  specified  above shall be deemed to constitute  Seller's
election  not to  eliminate or cure any such Title Defect or to satisfy any such
Title  Requirements.  If Seller  elects  (or is deemed to have  elected)  not to
eliminate  or cure any Title  Defects or to not satisfy any Title  Requirements,
the Buyer shall have the right,  by written  notice  delivered to Seller  within
five (5) business days of Seller's Title Notice or within five (5) business days
after the  expiration  of the time  period  during  which  Seller is entitled to
deliver  Seller's Title Notice,  whichever occurs first, to either (i) waive its
prior  notice as to the Title  Defects  which Seller has elected not to cure and
those Title  Requirements  which  Seller has  elected  not to  satisfy;  or (ii)
terminate this Agreement as provided later in this section.  Buyer's  failure to
deliver any written  notice  within such five (5) business day period shall be a
conclusive  presumption  that Buyer has  approved the Title  Documents  and this
Agreement shall remain in full force and effect.

      (b)  Buyer's  review of the Seller  Information  provided  to Buyer as set
forth above.

      (c) Buyer's review of the physical and environmental  characteristics  and
condition of the Property. Seller agrees to provide Buyer access to the Property
following the Agreement Date for the purpose of performing, at Buyer's sole cost
and expense,  studies,  physical  inspections,  investigations  and tests on the
Property (the "Studies"), provided that no such tests shall be conducted without
at least two (2) business  days prior  notice to Seller  (which may be oral) and
Seller's  prior   approval  of  such  Studies,   which  approval  shall  not  be

                                       4



unreasonably  withheld,  conditioned  or  delayed.  Buyer's  access  is  further
conditioned  on Seller  having a  representative  accompany  Buyer  and  Buyer's
consultants and Buyer providing Seller with certificates of insurance evidencing
that Buyer's  agents or  contractors  performing  said Studies have insurance in
types  and  amounts  satisfactory  to  Seller  as  determined  by  Seller in its
reasonable  discretion.  Buyer shall be required  to conduct  such  Studies in a
manner as to not  disturb or  interfere  with the  current  use of the  Property
(which may require more than two (2) business  days' notice for certain types of
invasive testing), and upon completion of such Studies, Buyer agrees at its sole
cost to restore the  Property to the  condition it was in  immediately  prior to
such Studies,  including,  but not limited to, the immediate removal of anything
placed on the Property in connection  with such Studies.  Copies of any reports,
letters or other written information generated as a result of such Studies shall
be provided to Seller.  Buyer shall indemnify,  defend (with counsel  reasonably
satisfactory to Seller),  protect, and hold Seller harmless from and against any
and  all  liability,   loss,  cost,  damage,  or  expense  (including,   without
limitation,  attorneys'  fees and costs)  which  Seller may  sustain or incur by
reason of or in connection  with any Studies made by Buyer or Buyer's  agents or
contractors relating to or in connection with the Property,  or entries by Buyer
or its agents or contractors  onto the Property;  provided,  however,  that such
indemnity  obligation  shall not include any liability,  loss,  cost,  damage or
expense  (including  attorneys' fees and costs) incurred by or asserted  against
Seller because of any existing  environmental  condition discovered or disclosed
by  such  Studies.  Notwithstanding  any  provision  to  the  contrary  in  this
Agreement, the indemnity obligations of Buyer under this Agreement shall survive
any  termination  of this Agreement or the delivery of the deed and the transfer
of title pursuant to this Agreement.

      (d) Seller shall use its good faith diligent  efforts to arrange a meeting
between  Buyer and a  representative  of each tenant.  Seller shall use its good
faith  diligent  efforts to obtain  from all  tenants of the  Property  estoppel
certificates  in the form  attached  as Exhibit C and to  deliver  same to Buyer
prior to the Approval Date, as such term is defined  immediately below.  Buyer's
Due Diligence period shall include Buyer's review and satisfaction with the form
and content of such estoppels.

      If on or before  5:00 p.m.  Pacific  time on the date that is thirty  (30)
days after the date this  Agreement has been fully executed by both parties (the
"Approval Date"),  Buyer notifies Seller in writing of Buyer's satisfaction with
the results of Buyer's Due Diligence Review (the "Approval  Notice"),  then this
Agreement shall remain in full force and effect and the Deposit shall be held by
the Escrow  Agent and  credited  to the  Purchase  Price at Closing as  provided
herein.  In the  event  Buyer  fails to  notify  Seller in  writing  of  Buyer's
satisfaction  with the results of Buyer's Due  Diligence  Review or in the event
Buyer  notifies  Seller  that it  disapproves  any  aspect of its Due  Diligence
Review,  on or before 5:00 p.m.  Pacific  time on the Approval  Date,  then this
Agreement  shall  terminate  without any  liability on the part of either party,
except for Buyer's indemnity  obligations set forth in paragraph 4 above. In the
event of such termination, the Earnest Money Note shall be returned to Buyer.

      5. Buyer's Conditions to Closing.  The following conditions are conditions
precedent to Buyer's obligation to purchase the Property:

                                       5




      (a)  Seller  maintaining  the  Property  in its  present  condition  until
Closing,  reasonable wear and tear excepted.  In the event that prior to Closing
the Property,  or any part thereof, is destroyed or materially damaged, and such
damage  exceeds  $250,000.00,  or if  condemnation  proceedings  (including  any
conveyance in lieu of condemnation)  are commenced  against the Property,  Buyer
shall have the right,  exercisable  by giving  notice of such decision to Seller
within ten (10) business  days after  receiving  written  notice of such damage,
destruction or condemnation  proceedings,  to terminate this Agreement, in which
case neither party shall have any further  rights or obligations  hereunder.  In
the event of such termination,  the Deposit shall be returned to Buyer. If Buyer
elects to accept the Property in its then  condition,  all proceeds of insurance
or condemnation  awards payable to Seller by reason of such damage,  destruction
or  condemnation  shall be paid or assigned to Buyer and Seller shall credit the
Purchase Price to the extent of any deductible  under any policies of insurance,
which  credit  shall not  exceed the  amount of such  damages.  In the event the
casualty  damage to the Property is $250,000.00 or less,  Buyer shall accept the
Property in its then  condition  and proceed  with the  purchase,  in which case
Buyer shall accept payment or assignment of applicable  insurance  proceeds,  if
any, from policies of insurance  maintained and paid for by Seller  covering the
Property  up  to  the  amount  necessary  to  make  the  necessary   repairs  or
restorations  and Seller shall  credit the  Purchase  Price to the extent of any
deductible  under any policies of  insurance,  which credit shall not exceed the
amount of such damages.

      (b) Delivery by Seller at Closing of the Deed.

      (c) Delivery by Seller of the  Assignment  and Assumption of Leases in the
form attached as Exhibit D.

      (d) Delivery by Seller of an  Assignment  of  Warranties,  Guaranties  and
Service Contracts in the form attached as Exhibit E.

      (e)  Performance  by Seller as and when required by this Agreement of each
and every term,  covenant,  condition and agreement  required to be performed by
Seller pursuant to this Agreement.

      In the event that the  conditions  set forth above in this paragraph 5 are
not satisfied (and Buyer is not otherwise in default of this  Agreement),  Buyer
may  terminate  this  Agreement,  subject to  paragraph  2(d)  hereof,  or waive
satisfaction  of the condition and close  escrow,  in either  instance by giving
written notice to Seller. In the event of such termination for reasons described
in (a) - (e) above, the Deposit shall be returned to Buyer.

      6. Seller's Conditions to Closing. The following conditions are conditions
precedent to Seller's obligation to sell the Property:

      (a)  Delivery  by Buyer at Closing of the  Purchase  Price,  the  executed
Assignment  and  Assumption  of Leases in the form attached as Exhibit D and the
executed Assignment of Warranties,  Guaranties and Service Contracts in the form
attached as Exhibit E.

                                       6




      (b)  Performance  by Buyer as and when required by this  Agreement of each
and every term,  covenant,  condition and agreement  required to be performed by
Buyer pursuant to this Agreement.

      In the event that the  conditions in this  paragraph 6 are not  satisfied,
Seller may elect, at its sole  discretion,  to terminate this Agreement or waive
satisfaction  of  the  condition  and  close  escrow.   In  the  event  of  such
termination, the Deposit shall be retained by Seller and shall be non-refundable
to the Buyer.

      7. The Closing.

      (a) The Closing  hereunder  shall be held and  delivery of all items to be
made at the  Closing  under  the  terms of this  Agreement  shall be made at the
offices of the Escrow  Agent  within ten (10)  business  days after the Approval
Date, or such other date prior thereto as Buyer and Seller may mutually agree in
writing  (the  "Closing  Date").  If the Closing does not occur on or before the
Closing Date, the Escrow Agent shall,  subject to the provisions of paragraph 2,
and unless it is  notified by both  parties to the  contrary,  within  three (3)
business  days after the Closing  Date,  return to the  depositor  thereof items
which may have been deposited pursuant to this Agreement (other than the Deposit
which shall be  distributed  as  required  above).  Any such  return  shall not,
however,  relieve  either  party  hereto  of any  liability  it may have for its
wrongful failure to close.

      (b)  At or  before  the  Closing,  Seller  shall  deliver  to  escrow  the
following:

            (i)   the Deed;

      (ii)  originals  or copies of all Leases and New  Leases  (and  amendments
thereto, if any) in Seller's actual and physical possession covering any portion
of the Property,  any security deposits relating thereto in Seller's possession,
and an executed  Assignment  and  Assumption  of Leases in the form  attached as
Exhibit D;

            (iii) Seller's  Non-Foreign  Certification  in the form  attached as
Exhibit F;

            (iv)  notices to the tenants in the form attached as Exhibit G;

            (v)   the executed Assignment of Warranties,  Guaranties and Service
Contracts in the form attached as Exhibit E; and

            (vi)  if  applicable,  an executed Bill of Sale in the form attached
as Exhibit H.

      Buyer may waive  compliance  on Seller's  part under any of the  foregoing
items by an instrument in writing.

                                       7




      (c) At or before the Closing,  Buyer shall  deliver to escrow the Purchase
Price, the executed  Assignment and Assumption of Leases in the form attached as
Exhibit D and the executed  Assignment  of  Warranties,  Guaranties  and Service
Contracts in the form attached as Exhibit E.

      (d) Seller and Buyer  shall each  deposit  such other  instruments  as are
reasonably  required by the Escrow Agent to close the escrow and  consummate the
purchase of the Property in accordance with the terms hereof.

      (e) Prorations

            (i)   The following  items shall be  apportioned  between Seller and
Buyer  effective at 12:01 a.m. on the date the Deeds are recorded and  pro-rated
on the basis of a 365-day year.

                  (A) Collected  Rent.  All  collected  rent  (excluding  tenant
reimbursements  for  Operating  Costs)  and  other  collected  income  (and  any
applicable  state or local tax on rent)  under  Leases in effect on the  Closing
Date shall be prorated as of the Closing.  Buyer shall be credited with any rent
and other income collected by Seller before Closing but applicable to any period
of time after  Closing.  Any rent  received  by Seller  after the  Closing  with
respect to time periods after the Closing shall be delivered to Buyer within ten
(10) days of Seller's  receipt.  Buyer  shall  apply rent and other  income from
tenants that are collected  after the Closing  first to the current  obligations
then owing to Buyer for its period of ownership and then remitting sums owing to
Seller with respect to periods prior to Closing,  if any, to Seller.  Buyer will
make  reasonable  efforts,  without  suit,  to collect any rents from tenants in
occupancy at Closing owed to Seller with respect to any period prior to Closing.
Seller may pursue  collection  as to any rent not  collected by Buyer within six
(6) months following the Closing Date,  provided that Seller shall have no right
to terminate any Lease or any tenant's  occupancy  under any Lease in connection
therewith. Seller is not restricted in any way from collecting any rent or other
income owed by past tenants who are no longer in occupancy at Closing.

                  (B) Operating Costs. Seller, as landlord under the Leases, may
be currently  collecting from tenants under the Leases  additional rent to cover
taxes, insurance, utilities (to the extent not paid directly by tenants), common
area   maintenance  and  other  operating  costs  and  expenses   (collectively,
"Operating Costs") in connection with the ownership, operation,  maintenance and
management of the Real Property.  Seller and Buyer shall each receive a debit or
credit,  as the case may be, for the  difference  between the  tenants'  current
account balances for Operating Costs and amount of Operating Costs  reimbursable
to Seller.  The parties shall reasonably  estimate  Operating Costs for Seller's
period of  ownership if final bills are not  available.  Those  Operating  Costs
being paid directly by a tenant shall not be prorated.  Operating Costs that are
not payable by tenants either directly or reimbursable under the Leases shall be
prorated between Seller and Buyer on an accrual basis.

                                       8




                  (C) Taxes and  Assessments.  Real estate taxes and  assessment
installments imposed by governmental  authority that are not yet due and payable
and that are not  reimbursable  by tenants  under the Leases as Operating  Costs
shall be  prorated as of the  Closing  based upon the most recent  ascertainable
assessed  values and tax rates.  Seller shall receive a credit for any taxes and
assessments  paid by Seller and applicable to any period after the Closing.  All
refunds or tax savings  relating to real estate taxes shall inure to the benefit
of Seller if such  refunds or tax savings  relate to any period for which Seller
owned the  Property.  Buyer shall remit to Seller any such refund or tax savings
relating to such period  immediately upon Buyer's  receipt,  after deducting any
amounts due to tenants under the Leases.  Any  additional  taxes relating to the
year of Closing  arising out of a change in the use of the  Property or a change
in ownership shall be assumed by Buyer effective as of Closing and paid by Buyer
when due and payable,  and Buyer shall indemnify Seller from and against any and
all such taxes, which indemnification obligation shall survive Closing.

                  (D) Final Adjustment After Closing. If final prorations cannot
be made at Closing for any item being  prorated  under this section,  then Buyer
and Seller agree to allocate  such items on an accrual basis as soon as invoices
or bills are  available  and  applicable  reconciliation  with tenants have been
completed,  with final adjustment to be made no later than sixty (60) days after
Closing.  Income and  expenses  shall be received  and paid by the parties on an
accrual  basis with  respect to their  period of  ownership.  Seller  shall not,
however,  be charged for any increase in Operating  Costs due to increased costs
incurred  by Buyer in respect of such  subsequent  to the  Closing.  Payments in
connection  with the final  adjustment  shall be due within  thirty (30) days of
written  notice.  Each party shall have  reasonable  access to, and the right to

expansion  or renewal  after the Closing  Date.  Leasing  commissions  or tenant
finish  costs that are payable on a monthly or other  periodic  basis during the
Lease  terms  shall be  prorated  between  the  parties  in the same  manner  as
Operating Costs. Any leasing  commissions and costs of tenant finish with regard
to new leases of the Property  entered into subsequent to the Agreement Date and
prior to Closing (the "New Leases")  shall be prorated  between Buyer and Seller
at Closing based upon the revenue from such New Leases  received by Seller prior
to  Closing  and the  revenue  to be  received  by Buyer for the term of the New
Leases after Closing.

            (iii) Tenant  Deposits.   All  tenant  security   deposits  actually
received  by Seller (and  interest  thereon if required by law or contract to be
earned  thereon) and not  theretofore  applied to tenant  obligations  under the
Leases or New Leases shall be transferred or credited to Buyer at Closing. As of
the Closing,  Buyer shall assume Seller's obligations related to tenant security
deposits.  Buyer shall  indemnify,  defend,  and hold Seller  harmless  from and
against

                                       9



all demands and claims made by tenants  with  respect to any  security  deposits
actually  transferred  or credited to Buyer and shall  reimburse  Seller for all
attorneys'  fees incurred or that may be incurred as a result of any such claims
or demands as well as for all loss, expenses, verdicts, judgments,  settlements,
interest, costs and other expenses incurred or that may be incurred by Seller as
a result of any such  claims or  demands by  tenants.  Seller  shall  indemnify,
defend,  and hold Buyer harmless from and against all demands and claims made by
tenants  with  respect to any security  deposits  not  actually  transferred  or
credited to Buyer and shall  reimburse Buyer for all attorneys' fees incurred or
that may be  incurred  as a result of any such  claims or demands as well as for
all loss, expenses, verdicts, judgments, settlements,  interest, costs and other
expenses  incurred  or that may be  incurred  by  Buyer as a result  of any such
claims or demands by tenants.

            (iv)  Utility  Deposits.  Buyer  shall take all steps  necessary  to
effectuate the transfer of all utilities to its name as of the Closing Date, and
where necessary, post deposits with the utility companies. Seller shall use good

            (v)   Insurance.  The fire,  hazard,  and other  insurance  policies
relating to the Property shall be cancelled by Seller as of the Closing Date and

                              Buyer:      BARRETT BUSINESS SERVICES, INC.,
                                          a Maryland corporation


                                          By:   /s/ Michael D. Mulholland
                                                -------------------------
                                          Name: Michael D. Mulholland
                                          Its:  VP-Finance and Secretary


      11.  Possession.  Subject to the rights of  tenants  and other  occupants,
Buyer shall have the right of possession on the Closing Date, provided, however,
that Seller shall allow authorized representatives of Buyer reasonable access to
the Property for the purposes of satisfying  Buyer with respect to  satisfaction
of any conditions precedent to the Closing contained herein.

      12. Tax-Deferred Exchange.  Buyer and Seller agree that, at either Buyer's
or Seller's sole election,  this transaction  shall be structured as an exchange
of like-kind properties under Section 1031 of the Internal Revenue Code of 1986,
as  amended  (the  "Code"),   and  the  regulations  and  proposed   regulations
thereunder.  The parties agree that if either wishes to make such  election,  it
must do so prior to the  Closing  Date.  If either so  elects,  the other  shall
reasonably  cooperate,  provided any such exchange is consummated pursuant to an
agreement  that is  mutually  acceptable  to Buyer and Seller and which shall be
executed and delivered on or before the Closing Date.  The electing  party shall
in all events be responsible  for all costs and expenses  related to the Section
1031 exchange and shall fully indemnify, defend and hold the other harmless from

reasonable attorneys' and paralegal fees and reasonable attorneys' and paralegal
fees on  appeal),  proceedings  and  causes  of  action  of any  kind or  nature
whatsoever  arising out of, connected with or in any manner related to such 1031
exchange  that would not have been  incurred  by the  non-electing  party if the
transaction  were a  purchase  for  cash.  The  provisions  of  the  immediately
preceding  sentence  shall survive  closing and the transfer of title to subject
Property to Buyer.  Notwithstanding  anything to the contrary  contained in this
paragraph,  any such Section 1031 exchange shall be consummated  through the use
of a facilitator or intermediary so that Buyer shall in no event be requested or
required to acquire title to any property other than the Property.

      13.  Confidentiality.  Buyer  agrees  not to  disclose  the  terms of this
Agreement or any  "Confidential  Information"  (as defined  below) to any party,
other than such Buyer's agents, accountants,  attorneys, employees,  consultants
and lender ("Buyer's Representatives") who have a need to know such information,

have a need to know such information,  without the Buyer's prior written consent
except as may be required by law.  Buyer will cause Buyer's  Representatives  to
observe  the terms of this  paragraph,  and Buyer  will be  responsible  for any
breach of this provision by Buyer or any of Buyer's Representatives. If Buyer or
any of Buyer's Representatives are requested pursuant to, or become compelled by
applicable  law,  regulation  or legal  process  to  disclose  any  Confidential
Information,  Buyer or Buyer's  Representative(s)  (as applicable)  will provide
Seller  with  prompt  notice  thereof  and agree to assist  Seller,  at Seller's
expense, to obtain protection of the Confidential  Information by court order or
otherwise.  If Buyer elects under rights  granted in this Agreement to terminate
this  Agreement,  Buyer will deliver to Seller  promptly  after its  termination
notice  copies of all  written  Confidential  Information  in Buyer' and Buyer's
Representatives'  possession  or control,  excepting  information  independently

owned or controlled by Buyer, provided that Seller is given prior written notice
and copies of the  applicable  documentation  confirming  such  assignment;  and
provided  further that any assignee by accepting  assignment  of this  Agreement
expressly agrees to assume all of Buyer's  obligations  under this Agreement and
that no such  assignment  shall relieve Buyer from its primary  liability  under

      (g) Enforcement.  In the event either party hereto fails to perform any of
its  obligations  under this  Agreement or if a dispute  arises  concerning  the
meaning or  interpretation  of any  provision of this  Agreement,  the party not
prevailing in such dispute shall pay any and all costs and expenses  incurred by
the  prevailing  party  in  enforcing  or  establishing  its  rights  hereunder,
including,  without  limitation,  court costs and  reasonable  attorneys'  fees,
whether incurred in mediation or arbitration,  at trial or on appeal,  or in any
bankruptcy  proceeding.  Each of Buyer and Seller  acknowledge  that it has been
advised by counsel as to its respective  rights,  duties and obligations in this

      (j) No  Recordation.  Neither Seller nor Buyer shall record this Agreement
or any  memorandum  thereof  in or among  the  land or  chattel  records  of any
jurisdiction.

      (k) Proper Execution.  The submission by Seller to Buyer of this Agreement
in unsigned form shall have no binding force and effect, shall not constitute an
option,  and shall not confer any rights upon Buyer or impose any obligations on
Seller  irrespective  of any  reliance  thereon,  change of  position or partial
performance  until Seller shall have  executed  this  Agreement  and the Earnest
Money Note shall have been received by the Escrow Agent.

      (l)  Computation  of Time.  The time in which any act is to be done  under
this  Agreement is computed by excluding  the first day, and  including the last
day,  unless the last day is a holiday or Saturday or Sunday,  and then that day
is also excluded.  Unless expressly indicated  otherwise,  (a) all references to
time shall be deemed to refer to Pacific  time;  and (b) all time periods  shall
expire at 5:00 p.m. Pacific time.

      IN WITNESS WHEREOF,  the parties hereto have executed this Agreement as of
the date first above written.
