                ANNOUNCES FOURTH QUARTER 2002 OPERATING RESULTS,
                            RESTATEMENT OF REVENUES,
                  PROGRESS TOWARDS BANK CREDIT FACILITY RENEWAL
                     AND SCHEDULES INVESTOR CONFERENCE CALL

     PORTLAND,  OREGON, March 19, 2003 - Barrett Business Services, Inc. (Nasdaq
trading  symbol:  "BBSI")  reported  today a net loss of $993,000 for the fourth
quarter ended December 31, 2002, an improvement of $1,276,000 from a net loss of
$2,269,000  for the fourth  quarter of 2001.  The diluted loss per share for the
2002 fourth quarter was $(.17) as compared to a diluted loss per share of $(.38)
for the same quarter a year ago. The net loss for 2002  totaled  $1,353,000,  an
improvement of $1,069,000 over the 2001 net loss of $2,422,000.

     The Company and several other publicly-traded PEO companies have determined
to restate PEO revenues  based upon Emerging  Issues Task Force Issue No. 99-19,
"Reporting Revenues Gross as a Principal versus Net as an Agent" ("EITF 99-19").
The restatement is predicated upon the  determination  that a PEO company is not
the primary obligor of the direct payroll costs of its PEO employees.  Under the
Company's new "net revenue"  reporting for PEO services,  the salaries and wages
of PEO  employees are no longer  recognized  as revenue  components by "netting"
such costs against PEO revenues.  The Company will provide comparative financial
information  within its future public filings and disclosures.  Pursuant to this
restatement,  total  revenues  for the fourth  quarter  ended  December 31, 2002
amounted to $25.7  million,  a decrease of  approximately  $6.5 million or 20.2%
from the $32.2  million for the same  quarter in 2001.  Total  revenues for 2002
were $109.3 million, a decrease of approximately $30.1 million or 21.6% from the
$139.4  million  for 2001.  The new  application  of EITF 99-19 has no effect on
gross margin dollars,  net income, cash flows, working capital and shareholders'
equity amounts previously  reported,  and will not affect such amounts in future
periods.

     The following  statements of operations are based upon the Company's  newly
adopted revenue recognition accounting policy of "net revenue" reporting for PEO
revenues pursuant to EITF 99-19:

Barrett Business Services, Inc.
News Release - 4th Quarter 2002
March 19, 2003



Operating  results  for the fourth  quarter  and the full year of 2001  included
$454,000 and $1,783,000 of goodwill amortization, respectively.

     William W. Sherertz, President and Chief Executive Officer, commented that:
"In spite of the reduction in workers'  compensation  expense in the 2002 fourth
quarter  both in terms of dollars and as a percent of  revenues,  as compared to
last year, we continue to be negatively affected by significantly  higher claims
costs in California. On a positive note, our strengthened branch management team
is beginning to achieve  increases in market share  leading to improved  revenue
trends thus far in 2003, particularly in California."

     The Company  also  announced  that it has reached an agreement in principle
with its primary bank in connection  with the scheduled  renewal of its existing
credit facility on April 30, 2003.

     The following  summarizes the unaudited balance sheets at December 31, 2002
