                AMENDED OPERATING RESULTS FOR FOURTH QUARTER AND
                      12-MONTHS ENDED DECEMBER 31, 2001 AND
                       SCHEDULES INVESTOR CONFERENCE CALL

      PORTLAND,  OREGON, April 3, 2002 - Barrett Business Services, Inc. (Nasdaq
trading  symbol:  "BBSI")  reported  today that it has  amended  its  previously
announced  operating  results for the 2001 fourth  quarter and  12-months  ended
December 31, 2001 by  recognizing  a $1,837,000  after-tax  charge in connection
with  post-year  end adverse  development  of the  estimated  future  expense of
workers' compensation claims and, to a lesser extent, an increased provision for
estimated  bad debt  expense  related to one  customer.  Of the total  after-tax
charge of $1,837,000  ($3,000,000  pretax),  $1,745,000  ($2,850,000 pretax) was
attributable  to higher  workers'  compensation  expense and  $92,000  ($150,000
pretax) was  related to an  increased  estimate  for bad debt  expense.  For the
fourth quarter ended  December 31, 2001, the Company's  amended net loss totaled
$2,269,000,  an increase of  $1,837,000  from the February 6, 2002  reported net
loss of  $432,000.  The basic and diluted net loss per share for the 2001 fourth
quarter  were  $.38.  Cash flow per share  (defined  as net (loss)  income  plus
depreciation  and  amortization  divided  by  weighted  average  diluted  shares
outstanding)  for the 2001 fourth  quarter was a negative  $.24. The amended net
loss for the year ended December 31, 2001 amounted to $2,422,000, an increase of
$1,837,000  from the  previously  reported net loss of  $585,000.  The basic and
diluted net loss per share for 2001 were $.39.  Cash flow per share for 2001 was
a positive $.14.

      Revenues for the 2001 fourth quarter and 12-months ended December 31, 2001
were unchanged at $50.7 million and $216.7 million, respectively.

      During  February and March 2002, the Company's  third party  administrator
("TPA")  for  California  workers'   compensation  claims  reported  significant
increases in the estimated future costs of claims to the Company.  The increases
in estimated  future costs were due in part to adverse  development  of previous
estimates for future claims  costs,  the TPA's recent  completion of a review of
all claims files it had assumed from the Company's  predecessor TPA during 2001,
and a change in claims reserving  practices mandated by the State of California.
Due to the increased  estimates for future claims costs, the Company engaged its
outside actuary to analyze the financial  effect of the revised costs estimates,
which in turn resulted in the Company's recognition of the additional charge for
workers' compensation expense for 2001.

      William W.  Sherertz,  President and Chief  Executive  Officer,  commented
that,  "I believe this charge will have  minimal,  if any,  effect on the future
cash flow of the Company,  as the increased  estimated  future claims expense is
primarily  related to older claims. It has been our experience that the newer or
current year injury claims precipitate greater cash needs because of the medical
attention required by our injured employees. From

an operational  standpoint,  a significant number of the older claims originated
from two customers served by one branch office.  We have made personnel  changes
at the branch and corporate  offices,  changed  customer  service  procedures to
ensure that we have a more  appropriate  match between the customers'  personnel
needs and our  available  employees,  and improved  communications  with our new
California  TPA  firm.  Although  the cost of  workers'  compensation  claims in
California is far higher than any other zone within the Company, we believe that
our management team has effectively  addressed the operational issues. On a more
positive  note,  we are  encouraged  that the  burden  of these  increased  cost
estimates  for prior  year  claims  will not  affect  current  and  future  year
earnings."
