NOTE 1 - BASIS OF PRESENTATION OF INTERIM PERIOD STATEMENTS:

            The  accompanying  financial  statements are unaudited and have been
prepared by Barrett  Business  Services,  Inc. (the  "Company")  pursuant to the
rules  and  regulations  of the  Securities  and  Exchange  Commission.  Certain
information  and note  disclosures  typically  included in financial  statements
prepared in accordance with generally accepted  accounting  principles have been
condensed or omitted pursuant to such rules and  regulations.  In the opinion of
management, the financial statements include all adjustments, consisting only of
normal recurring adjustments,  necessary for a fair statement of the results for
the interim  periods  presented.  The  preparation  of financial  statements  in
conformity with generally accepted accounting  principles requires management to
make estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results may differ from such estimates
and assumptions. The financial statements should be read in conjunction with the
audited  financial  statements and notes thereto  included in the Company's 1999
Annual  Report on Form 10-K at pages F1-F21.  The results of  operations  for an
interim period are not necessarily indicative of the results of operations for a
full year.

            Certain  prior year amounts have been  reclassified  to conform with
the 2000 presentation. Such reclassifications had no effect on gross margin, net
income or stockholders' equity.

      Net  income  for the third  quarter of 2000 was  $500,000,  a decrease  of
$1,335,000 or 72.8% from the same period in 1999. The decrease in net income for
2000 was attributable  primarily to a decline in the Company's revenues compared
to recent  quarters,  combined with increased  workers'  compensation and direct
payroll  costs,  both in terms of dollars and as a percentage  of revenues,  and
higher depreciation and amortization,  offset in part by lower selling,  general
and administrative  expenses. Basic and diluted earnings per share for the third
quarter of 2000 were $.07,  which  compares  to basic and diluted  earnings  per
share of $.24 for the 1999 third quarter.

Item 2.  MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (Continued)

Results of Operations (continued)
- ---------------------------------

      Revenues  for the  third  quarter  of  2000  totaled  approximately  $80.7
million,  a  decrease  of  approximately  $15.2  million or 15.8% from the third
quarter of 1999. In terms of geographic  revenue  trends for the Company's  five
operating  zones,  the Southern  California  and  Mid-Atlantic  operating  zones
experienced the largest percentage decline in quarter-over-quarter revenues. The
Company's revenues continue to be adversely affected by the reduced availability
of qualified  employees in a low unemployment  economy, as well as the Company's
decision  to  terminate  its   relationship   with  certain   customers  due  to
unacceptable profit margins or risks associated with credit or workplace safety.
In an effort to improve future operating  results,  management is (i) continuing
to impose  higher  rates for the  Company's  services  to  reflect  the  current
imbalance  between  the  demand for and supply of  qualified  employees  for its
customers and (ii) seeking additional  opportunities to reduce selling,  general
and administrative ("SG&A") expenses.

      Staffing  services revenue decreased  approximately  $6.6 million or 11.6%
primarily due to a shortage of available  qualified personnel in the majority of
areas in which the Company does business. Professional employer ("PEO") services
revenue  decreased  approximately  $8.6  million  or  21.7%,  primarily  due  to
management's decision to discontinue the Company's services to certain customers
who were not generating  acceptable gross margins.  The decrease in PEO services
revenue resulted in an increase in the share of staffing  services from 58.9% of
total  revenues for the third  quarter of 1999 to 61.8% for the third quarter of
2000. The share of revenues for PEO services had a  corresponding  decrease from
41.1% of total  revenues  for the third  quarter  of 1999 to 38.2% for the third
quarter of 2000.

      Gross  margin for the third  quarter of 2000  totaled  approximately  $7.9
million,  which  represented  a decrease of $3.0 million or 27.7% from the third
quarter of 1999. The gross margin  percent  decreased from 11.4% of revenues for
the third quarter of 1999 to 9.8% for the third quarter of 2000. The decrease in
the gross margin percentage was due to higher workers'  compensation expense and
direct payroll costs and slightly  higher  payroll taxes and benefits.  Workers'
compensation  expense for the third quarter of 2000 totaled $3.4 million or 4.2%
of  revenues,  which  compares to $3.0  million or 3.2% of revenues for the same
period in 1999. The increase in workers' compensation expense for the 2000 third
quarter, as a percentage of revenues,  was generally attributable to an increase
in the  expected  total  costs of claims in 2000  compared to the same period in
1999. The increase in direct payroll costs,  as a percentage of revenues for the
third quarter of 2000,  was primarily due to increases in contract  staffing and
on-site  management,  which generally have a lower mark-up rate (and thus higher
direct  payroll  costs as a percentage of revenues)  relative to other  staffing
services provided by the Company. The increase in payroll taxes and benefits,

         RESULTS OF OPERATIONS (Continued)

Results of Operations (continued)

as a  percentage  of  revenues  for the third  quarter  of 2000,  was  primarily
attributable to increased direct payroll in California, which has a higher state
unemployment tax rate as compared to other states in which the Company operates.

      SG&A expenses for the 2000 third quarter  amounted to  approximately  $6.1
million,  a decrease of $829,000  or 11.9% from the  comparable  period in 1999.
SG&A  expenses,  expressed as a percentage of revenues,  increased from 7.3% for
the third quarter of 1999 to 7.6% for the third quarter of 2000. The decrease in
total SG&A  dollars from 1999 was  primarily  attributable  to lower  management
payroll, branch profit sharing and related payroll taxes.

      Depreciation and amortization totaled $820,000 or 1.0% of revenues for the
third  quarter of 2000,  which  compares to $691,000 or 0.7% of revenues for the
same period in 1999.  The  increased  expense was  primarily due to the March 1,
2000 implementa-tion of the Company's new information system.

      Other expense  totaled  $122,000 or 0.2% of revenues for the third quarter
of 2000, which compares to $138,000 or 0.1% of revenues for the third quarter of
1999. The small decrease in expense was primarily  attributable to slightly less
net interest expense on lower debt levels during the third quarter of 2000.

      The  Company  offers  various  qualified  employee  benefit  plans  to its
employees,  including its worksite  employees.  These qualified employee benefit
plans include a savings plan under Section  401(k) of the Internal  Revenue Code
(the  "Code"),  a cafeteria  plan under Code Section 125, a group health plan, a
group life  insurance plan and a group  disability  insurance  plan.  Generally,
qualified  employee benefit plans are subject to provisions of both the Code and
the Employee  Retirement Income Security Act ("ERISA").  In order to qualify for
favorable tax treatment under the Code,  qualified plans must be established and
maintained by an employer for the  exclusive  benefit of its  employees.  In the
event  the  tax  exempt  status  of  the  Company's  benefit  plans  were  to be
discontinued and the benefit plans were to be  disqualified,  such actions could
have a material adverse effect on the Company's  business,  financial  condition
and results of  operations.  Reference  is made to pages 19-20 of the  Company's
1999 Annual Report on Form 10-K for a more detailed discussion of this issue.

                Nine Months Ended September 30, 2000 and 1999

      Net income for the nine months ended September 30, 2000 was $2,038,000,  a
decrease of  $1,752,000  or 46.2% from the same period in 1999.  The decrease in
net income was  attributable  to a lower gross margin percent owing primarily to
higher direct

payroll  costs,  payroll taxes and benefits and workers'  compensation  expense,
expressed as a  percentage  of revenues,  coupled with higher  depreciation  and
amortization and interest expense.  Basic and diluted earnings per share for the
first nine months of 2000 were $.28 and $.27, respectively,  as compared to $.50
for both basic and diluted earnings per share for the same period of 1999.

      Revenues   for  the  nine  months   ended   September   30,  2000  totaled
approximately  $254.4 million, an increase of approximately $2.8 million or 1.1%
over the similar  period of 1999.  The increase in total  revenues was primarily
due to the TSU acquisition, which was effective May 31, 1999.

      Gross  margin  for the  nine  months  ended  September  30,  2000  totaled
approximately  $25.3  million,  which  represented a decrease of $2.1 million or
7.7% from the similar period of 1999.  The gross margin  percent  decreased from
10.9% of revenues for the nine-month  period of 1999 to 9.9% for the same period
of 2000. The decrease in the gross margin percentage was primarily due to higher
direct  payroll  costs and payroll  taxes and  benefits.  The increase in direct
payroll costs,  as a percentage of revenues,  was  attributable  to increases in
contract staffing and on-site management,  of which payroll generally represents
a higher percentage of revenues.  The increase in payroll taxes and benefits for
the nine-month  period of 2000 was primarily  attributable  to increased  direct
payroll  in  California,  which  has a  higher  state  unemployment  tax rate as
compared to other states in which the Company operates. The increase in workers'
compensation  expense was generally  attributable to an increase in the expected
total  costs of claims and a higher  incidence  of  injuries  in the nine months
ended September 30, 2000 compared to the similar period in 1999.

      SG&A  expenses for the nine months ended  September  30, 2000  amounted to
approximately  $19.1  million,  an increase of $146,000 or 0.8% over the similar
period of 1999. SG&A expenses,  expressed as a percentage of revenues,  remained
constant at 7.5% for the  nine-month  periods of 1999 and 2000.  The increase in
total SG&A dollars was primarily due to increased bad debt expense,  advertising
and legal  expenses,  offset in part by lower branch profit  sharing and related
payroll taxes.

      Depreciation and amortization totaled $2.4 million or 0.9% of revenues for
the nine months ended September 30, 2000, which compares to $1.8 million or 0.7%
of revenues for the same period of 1999. The increased expense was primarily due
to  the   amortization   arising  from  the  acquisition  of  TSU  coupled  with
depreciation  and  amortization  from the  March 1, 2000  implementation  of the
Company's new information system.

      Other  expense  totaled  $405,000 or 0.2% of revenues  for the  nine-month
period ended  September 30, 2000,  which compares to $80,000 or 0.1% of revenues
for the  comparable  1999 period.  The increase in expense was  primarily due to
higher net interest  expense related to debt incurred  effective May 31, 1999 in
connection with the TSU acquisition.

Fluctuations in Quarterly Operating Results
- -------------------------------------------

      The Company has historically  experienced significant  fluctuations in its
quarterly  operating  results and expects such  fluctuations  to continue in the
future. The Company's operating results may fluctuate due to a number of factors
such as  seasonality,  wage  limits on  payroll  taxes,  claims  experience  for
workers' compensation, demand and competition for the Company's services and the
effect of acquisitions.  The Company's  revenue levels fluctuate from quarter to
quarter  primarily  due to the impact of  seasonality  in its staffing  services
business  and on  certain  of its PEO  clients  in the  agriculture  and  forest
products related industries.  As a result, the Company may have greater revenues
and net income in the third and fourth  quarters  of its  fiscal  year.  Payroll
taxes and benefits fluctuate with the level of direct payroll costs but may tend
to represent a smaller percentage of revenues later in the Company's fiscal year
as federal  and state  statutory  wage limits for  unemployment  and to a lessor
extent  social  security  taxes  are  exceeded  by  some   employees.   Workers'
compensation  expense  varies with both the  frequency and severity of workplace
injury claims reported during a quarter,  as well as adverse loss development of
prior period claims during the current or subsequent quarters.

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

      The Company's cash position of $351,000 at September 30, 2000  represented
a decrease of $199,000  from  December 31,  1999.  The decline in the first nine
months of 2000 compares to a decrease of $4,029,000 for the comparable period in
1999.  The decrease in cash at September  30, 2000,  as compared to December 31,
1999, was primarily attributable to cash used to repurchase the Company's common
stock, payments on credit-line  borrowings and payments on long-term debt issued
in connection with the 1999 TSU  acquisition,  partially offset by cash provided
by net income and depreciation and amortization.

      Net cash  provided  by  operating  activities  for the nine  months  ended
September 30, 2000  amounted to  $7,412,000,  as compared to $2,741,000  for the
comparable 1999 period. For the 2000 period,  cash flow was primarily  generated
by net

income,  together with noncash  expenses of depreciation  and amortization and a
decrease in accounts receivable, partially offset by an increase in deferred tax
assets and a decrease in accrued payroll, payroll taxes and related benefits.

      Net cash used in investing activities totaled $845,000 for the nine months
ended  September  30,  2000,  as compared to  $14,652,000  for the similar  1999
period. For the 2000 period, the principal use of cash for investing  activities
was for costs associated with the March 1, 2000  implementation of the Company's
new  management  information  system.  The  Company  presently  has no  material
long-term capital  commitments.  For the 1999 period,  the principal use of cash
was for the acquisition of three staffing service businesses.

      Net cash used in  financing  activities  for the  nine-month  period ended
September  30,  2000 was  $6,766,000,  which  compared  to  $7,882,000  net cash
provided by  financing  activities  for the similar  1999  period.  For the 2000
period, the principal use of cash in financing activities was $2,103,000 of cash
used to repurchase  the Company's  common stock,  $1,967,000 of payments made on
credit-line  borrowings  and  $1,859,000  of payments  made on  long-term  debt,
primarily the $8,000,000  three-year  term loan in connection with the Company's
acquisition of TSU.

      The  Company's  business  strategy is based in part on growth  through the
expansion of operations at existing  offices,  together with the  acquisition of
additional personnel-related  businesses, both in its existing markets and other
strategic   geographic  areas.  The  Company  explores   proposals  for  various
acquisition  opportunities  on an ongoing  basis,  but there can be no assurance
that any additional transactions will be consummated.

      The Company  maintains a credit  arrangement with its principal bank which
provides for an  unsecured  revolving  credit  facility of $15.0  million.  This
facility,  which  expires May 31,  2001,  includes a  subfeature  for letters of
credit, as to which  approximately $2.6 million were outstanding as of September
30, 2000.  Management  believes  that the credit  facility  and other  potential
sources of financing, together with anticipated funds generated from operations,
will be sufficient in the aggregate to fund the Company's  working capital needs
for the foreseeable future.

      During  1999,  the  Company's  board  of  directors   authorized  a  stock
repurchase program.  Since inception,  the board has approved three increases in
the total number of shares authorized to be repurchased under this program.  The
repurchase  program  currently allows for the repurchase of up to 950,000 common
shares from time to time in open market purchases.  During the first nine months
of 2000, the Company

repurchased  380,500  shares  at an  aggregate  price of  $2,103,000.  Since the
inception of the repurchase  program  through  November 8, 2000, the Company has
repurchased  648,800  shares for an aggregate  price of  $3,848,000.  Management
anticipates that the capital  necessary to continue to execute this program will
be provided by existing cash balances and other available sources of financing.

Inflation
- ---------

      Inflation  generally  has not been a  significant  factor in the Company's
operations  during the  periods  discussed  above.  The  Company  has taken into
account  the  impact  of  escalating  medical  and other  costs in  establishing
reserves for future expenses for self-insured workers' compensation claims.

Litigation Reform Act of 1995. Such forward-looking statements involve known and
unknown  risks,  uncertainties  and other  factors  that may  cause  the  actual

Item 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

      The  Company's  exposure  to market  risk for  changes in  interest  rates
primarily relates to the Company's short-term and long-term debt obligations. As
of September 30, 2000,  the Company had  interest-bearing  debt  obligations  of
approximately $9.2 million,  of which  approximately $7.6 million bears interest
at a variable rate and  approximately  $1.6 million at a fixed rate of interest.
The variable rate debt is comprised of  approximately  $2.9 million  outstanding
under an  unsecured  revolving  credit  facility,  which  bears  interest at the
Federal  Funds rate plus  1.25% or LIBOR plus  1.00%.  The  Company  also has an
unsecured  three-year term note with its principal bank, which bears interest at
LIBOR plus 1.35%.  Based on the Company's overall interest exposure at September
30, 2000, a 10 percent change in market interest rates would not have a material
effect on the fair  value of the  Company's  long-term  debt or its  results  of
operations.  As of  September  30,  2000,  the Company had not entered  into any
interest rate instruments to reduce its exposure to interest rate risk.
