PROMISSORY NOTE


$60,000                          Portland, Oregon              December 10, 2001


            1. Promise to Pay. For value received,  the undersigned,  William W.
Sherertz  ("Maker"),  promises to pay, in lawful money of the United States,  to
Barrett Business Services,  Inc., a Maryland corporation ("Holder"),  at 4724 SW
Macadam Avenue,  Portland,  Oregon 97201, the unpaid  principal  balance of this
Note,  which total  unpaid  principal  amount  shall not exceed  Sixty  Thousand
Dollars ($60,000), together with interest on the principal balance, from time to
time,  outstanding  at the interest  rate  hereinafter  provided,  in the manner
hereinafter  described.  This Note is given to evidence  Maker's  obligation  to
repay all sums which Holder may, from time to time,  advance to Maker  hereunder
("Advances").

            2. Principal  Balance.  The unpaid principal balance of all Advances
on this Note  ("Principal  Balance") at one time shall not exceed Sixty Thousand
Dollars ($60,000).

            3. Line of Credit  Provisions  (Advances).  Holder may, from time to
time,  advance  sums to the Maker.  No  Advances  shall be made  which  create a
maximum amount  outstanding at any one time which exceed Sixty Thousand  Dollars
($60,000).  However, Advances hereunder may be borrowed,  repaid, and reborrowed
and the aggregate Advances loaned hereunder,  from time to time, may exceed such
maximum.  Each Advance hereunder shall be made at the sole option of Holder. Any
Advance that is made shall become part of this Note.  Holder's records shall, at
any time, be  conclusive  evidence of the unpaid  balance and interest  owing on
this Note.

            4. Interest. Maker promises to pay interest on the Principal Balance
at a per annum rate which is equal to Wells Fargo Bank's (the "Bank") prime rate
less 1.50  percentage  points.  For  example,  if the Bank's  prime rate is five
percent  (5%) and the Maker has  promised to pay a rate which is 1.5  percentage
points  below the Bank's  prime rate,  the  interest  rate is three and one-half
percent (3.5%).  The interest rate shall be adjusted without notice effective on
the day the Bank's  prime rate  changes.  All  interest  will be computed at the
applicable rate based on a 360 day year and applied to the actual number of days
elapsed, commencing with the date of Advance.

            5. Payment:

            5.1 Principal shall be paid on demand.

            5.2 Interest shall be paid at the time principal is due.

            6. Waiver.  To the extent  permitted  by law,  each and every maker,
surety,  guarantor,  endorser,  or signator to this Note, in whatever  capacity,
hereby waives  presentment,  demand,  protest,  notice of dishonor and all other
notices,  and agrees that Holder may exercise  Holder's rights  hereunder in any
order and at any time, and may, without notice to or consent of any such person,
and without in any way  diminishing the obligations of any such person deal

                                      -1-


with  any  such  person  with  reference  to this  Note  by way of  forbearance,
extension,  modification,  compromise,  or otherwise.  Any such action(s)  taken
under the  preceding  sentence may be taken  against  one,  all, or some of such
persons,  and Holder  may take any such  action  against  one  differently  than
another of such persons, in Holder's sole discretion.

            7. Default; Default Rate. Time is material and of the essence hereof
with respect to the payment of any sums of any nature by and the  performance of
all duties or obligations of the Maker.  Each of the following shall be an Event
of Default under this Note: (a) failure to make any payment of principal  and/or
interest or any other  payment  required by the  provisions  of this Note on the
date such payment or payments are due and such payment or payments  shall remain
unpaid for 30 days after written notice from Holder;  (b) failure to perform any
other  provision  of this Note;  or (c) falsity in any  material  respect of any
representation, warranty, or information furnished by Maker or Maker's agents to
Holder in connection with the loan evidenced by this Note (the "Loan"). Upon the
occurrence  of any Event of Default,  any sum not paid as provided in this Note,
shall, at the option of Holder, without notice, bear interest from such due date
at a rate of interest (the "Default  Rate") equal to two (2)  percentage  points
per annum greater than the then  interest  rate, or the maximum rate of interest
permitted  by law,  whichever is the lesser,  and, at the option of Holder,  the
unpaid  balance of principal,  accrued  interest,  plus any other sums due under
this  Note  shall at once  become  due and  payable,  without  notice  except as
described in paragraph 13, and shall bear interest at the Default Rate.

            8.    Acknowledgments Regarding Default Rate.

            8.1 Maker  acknowledges  and agrees that (i) a default in making the
payments  herein agreed to be paid when due will result in the Holder  incurring
additional expense in servicing the Loan, loss to Holder of the use of the money
due, and in frustration to Holder in meeting Holder's other commitments, (ii) if
for any reason  Maker fails to pay any amounts due  hereunder,  Holder  shall be
entitled to damages for the detriment  caused thereby,  but that it is extremely
difficult and impractical to ascertain the extent of such damages, and (iii) the
Default Rate described in this Note is a reasonable estimate of such damages.

            8.2 Maker represents that Maker fully  understands the effect of the
charges,  waiver,  and agreement  contained above. Maker acknowledges and agrees
that the  making of the Loan by Holder at the  interest  rate and with the other
terms described herein is sufficient consideration for such charges, waiver, and
agreement,  and that Holder would not make this Loan on these terms without such
charges, waiver, and agreement.

            9. Expenses and Attorneys Fees. If Holder is the prevailing party in
any litigation instituted in connection with the Note; or if Holder or any other
person  initiates  any judicial or  nonjudicial  action,  suit, or proceeding in
connection  with the Note and an attorney is employed by Holder to (a) appear in
any action, suit, or proceeding,  or (b) reclaim, seek relief from a judicial or
statutory stay, sequester, protect, preserve or enforce Holder's interest in the
Note  (including,  but not limited to,  proceedings at appellate  levels,  under
federal  bankruptcy  law, under probate  proceedings,  or in connection with any
state or federal tax lien),  then, in any such event,  Maker shall pay attorneys
fees and costs and  expenses  incurred  by Holder  and/or  Holder's  attorney in
connection  with the  above-mentioned  events  and any  appeals  related to such
events,  including,  but not limited to, costs. If not paid within ten (10) days
after such fees,  costs,  and

                                      -2-


expenses  become due and written  demand for  payment is made upon  Maker,  such
amount may, at Holder's option,  be added to the principal of the Note and shall
bear interest at the Default Rate.

            10. No Usury. In no event shall any payment of interest or any other
sum  payable  hereunder  both (a)  violate  the usury laws of this state and (b)
allow Maker to bring a claim for usury or raise usury as a defense in any action
on this Note. If it is established that both (a) and (b) have occurred,  and any
payment  exceeding  lawful  limits has been  received,  Holder shall refund such
excess or, at Holder's option,  credit the excess amount to principal,  but such
payments  shall not affect the  obligation  to make periodic  payments  required
herein.

            11.  Security.  The  indebtedness  evidenced  by  this  Note  is not
secured.

            12. Due on Transfer:

            12.1 The Loan is personal to Maker and not assignable. In making it,
Holder has relied on Maker's credit and the financial  market  conditions at the
time the Loan is made. In the event of an assignment, conveyance, or transfer of
this Note,  directly or indirectly,  either  voluntarily,  involuntarily,  or by
operation of law, Holder may declare the entire balance of this Loan immediately
due and payable.

            12.2  Assumption  shall NOT release  Maker or  successor in interest
from personal  liability for payment and performance of the terms and conditions
of this Note.

            13.  Notice  and  Opportunity  to Cure.  Notwithstanding  any  other
provision of this Note,  Holder shall not accelerate  the sums evidenced  hereby
because of a Nonmonetary  Default (defined below) by Maker unless Maker fails to
cure the default  within 30 days of the date on which  Holder  mails or delivers
written  notice of the default to Maker.  For  purposes  of this Note,  the term
"Nonmonetary  Default" means a failure by Maker or any other person or entity to
perform any obligation  contained in the Note, other than the obligation to make
payments provided for in the Note. If a Nonmonetary  Default is capable of being
cured and the cure cannot reasonably be completed within the 30 day cure period,
the cure period  shall be extended up to 60 days so long as Maker has  commenced
action to cure within the 30 day cure period, and in Holder's opinion,  Maker is
proceeding to cure the default with due diligence.  None of the foregoing  shall
be construed to obligate  Holder to forbear in any other manner from  exercising
Holder's  remedies  and Holder may pursue  any other  rights or  remedies  which
Holder may have because of a default.

            14. Commercial  Purposes.  The obligation  evidenced by this Note is
exclusively for commercial or business purposes.

            15.  Governing  Law. The law of the state of Oregon shall govern the
validity, interpretation, construction and performance of this Note.


                                      -3-



            16.  Successors  and  Assigns.   Whenever  used  herein,  the  words
"undersigned," "Maker," and "Holder" shall be deemed to include their respective
heirs, personal representatives, successors, and assigns.

            Maker:                         /s/ William W. Sherertz
