                   Notes to Consolidated Financial Statements


Note 1 - Basis of Presentation of Interim Period Statements

      The accompanying  consolidated financial statements are unaudited and have
been prepared by Barrett Business Services,  Inc.  ("Barrett" or 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 accounting  principles generally accepted
in the United States of America have been condensed or omitted  pursuant to such
rules and regulations.  In the opinion of management, the consolidated 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  ("GAAP") 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  consolidated  financial  statements  should  be  read in
conjunction with the audited financial  statements and notes thereto included in
the Company's  2004 Annual Report on Form 10-K at pages F1 - F25. 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 current year  presentation.  Such  reclassifications  had no
impact on gross margin, net income or stockholders' equity.

      During  May 2004,  the  Company  formed a  wholly-owned  subsidiary  which
acquired an aircraft.  The subsidiary incurred debt of $1,475,000 to finance the
purchase of the aircraft.  The  consolidated  financial  statements  include the
accounts of the  subsidiary,  after  elimination  of  intercompany  accounts and
transactions.

      Barrett, a Maryland corporation, is engaged in providing both staffing and
professional  employer  services to a diversified  group of customers  through a
network of branch offices  throughout  California,  Oregon,  Washington,  Idaho,
Arizona, Maryland, Delaware and North Carolina. Staffing services are engaged by
customers  to  meet  short-term  and  long-term  personnel  needs.  Professional
employer  services ("PEO") are normally used by organizations to satisfy ongoing
human resource  management needs and typically  involve contracts with a minimum
term of one year, renewable annually,  which cover all employees at a particular
work site.

      Comprehensive income (loss) includes all changes in equity during a period
except those that resulted from  investments by or  distributions to a company's
stockholders.  Other comprehensive  income (loss) refers to revenues,  expenses,
gains and  losses  that  under  generally  accepted  accounting  principles  are
included in comprehensive  income (loss),  but excluded from net income as these
amounts  are  recorded  directly  as  an  adjustment  to  stockholders'  equity.
Barrett's other  comprehensive  income (loss) is comprised of unrealized holding
gains and losses on its publicly traded marketable  securities,  net of realized
gains included in net income.


Note 2 - Recent Accounting Pronouncements

      On December 16, 2004, the FASB issued SFAS 123(R),  "Share-Based Payment,"
which is a revision of SFAS 123, "Accounting for Stock-Based Compensation." SFAS
123(R)  supersedes  APB  Opinion  No.  25,   "Accounting  for  Stock  Issued  to
Employees," and amends SFAS No. 95,  "Statement of Cash Flows."  Generally,  the
approach  in SFAS  123(R) is  similar  to the  approach  described  in SFAS 123,
however, SFAS 123(R) requires all share-based

payments to employees, including grants of employee stock options, to be
expensed in the income statement over the requisite service period based on
their grant-date fair values. Pro forma disclosure is no longer an alternative.
SFAS 123(R) allows for either prospective or retrospective adoption and requires
that the unvested portion of all outstanding awards upon adoption be recognized
using the same fair value and attribution methodologies previously determined
under SFAS 123. The Company is currently evaluating transition alternatives and
valuation methodologies for future grants. As a result, proforma compensation
expense, as described in Note 6, may not be indicative of future expense to be
recognized under SFAS 123(R). SFAS 123(R) must be adopted no later than January
1, 2006 and the Company expects to adopt SFAS 123(R) by such date. The effect of
adoption of SFAS 123(R) on the Company's financial position or results of
operations has not yet been determined.


Note 3 - Acquisition

      Effective  January 1, 2004, the Company  acquired certain assets of Skills
Resource  Training Center ("SRTC"),  a staffing services company with offices in
Central Washington,  Eastern Oregon and Southern Idaho. The acquisition provided
the Company with the  opportunity  to  geographically  expand and  diversify its
business,   particularly  in  the  agricultural,  food  packing  and  processing
industries.  The Company paid  $3,000,000 in cash for the assets of SRTC and the
selling  shareholders'  noncompete  agreements and agreed to issue up to 135,731
shares of its common stock ("Earnout Shares"), with the actual number of Earnout
Shares to be issued  based upon the level of financial  performance  achieved by
the SRTC offices during calendar 2004. Certain  contingencies remain unresolved,
precluding a final calculation of the Earnout Shares.  The Company has, however,
recorded  estimated  total Earnout  Shares of 52,800 with a value of $778,000 on
its consolidated balance sheet as of December 31, 2004. The transaction resulted
in  $3,767,000 of goodwill,  $40,000 of  intangible  assets and $15,000 of fixed
assets. The Company's  consolidated income statements includes SRTC's results of
operations since January 1, 2004.


Note 4 - Basic and Diluted Earnings Per Share

      Basic earnings per share are computed based on the weighted average number
of common  shares  outstanding  during the period.  Diluted  earnings  per share
reflect the  potential  effects of the exercise of  outstanding  stock  options.
Basic and diluted shares outstanding are summarized as follows:

Note 5 - Stock Incentive Plans

      The Company's 2003 Stock Incentive Plan (the "2003 Plan"),  which provides
for stock-based awards to Company employees,  non-employee directors and outside
consultants  or advisors,  was  approved by  shareholders  on May 14,  2003.  No
options  have been  issued to outside  consultants  or  advisors.  The number of
shares of common stock reserved for issuance under the 2003 Plan is 400,000.  No
new grants of stock options may be made under the Company's 1993 Stock Incentive
Plan (the "1993 Plan").  At March 31, 2005,  there were option  awards  covering
313,386 shares  outstanding  under the 1993 Plan,  which, to the extent they are
terminated  unexercised,  will be  carried  over  to the  2003  Plan  as  shares
authorized  to be issued  under the 2003 Plan.  Outstanding  options  under both
plans generally become exercisable in four equal annual  installments  beginning
one year after the date of grant and  expire ten years  after the date of grant.
The  exercise  price of incentive  stock  options must not be less than the fair
market value of the Company's stock on the date of grant.

Note 6 - Stock Option Compensation

      The Company  applies APB  Opinion  No. 25 and related  interpretations  in
accounting for its stock incentive plan.  Accordingly,  no compensation  expense
has been  recognized  for its stock option grants issued at market price because
the exercise  price of the Company's  employee  stock options  equals the market
price of the underlying stock on the date of the grant.

      If compensation  expense for the Company's  stock-based  compensation plan
had been determined  based on the fair market value at the grant date for awards
under the 2003 Plan consistent with the method of SFAS No. 123,  "Accounting for

Note 7 - Subsequent Event - Stock Split

      On April 15,  2005,  the board of  directors  of the  Company  approved  a
3-for-2 stock split, which will be effected by a stock dividend.  The additional
shares to be issued  will be  distributed  on May 19,  2005 to  stockholders  of
record at the close of business on April 29, 2005.  On a split  adjusted  basis,
diluted  earnings per share for the 2005 first  quarter would have been $.10, as
compared to $.07 for the 2004 first quarter.

      The Company  changed its reporting of PEO revenues from a gross basis to a
net basis in 2002 because it was determined that the Company was not the primary
obligor for the  services  provided by employees  pursuant to its PEO  contracts
with its customers.  Gross revenue information,  although not in accordance with
GAAP, is presented below because  management  believes such  information is more
informative as to the level of the Company's  business  activity and more useful
in managing its operations.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations (Continued)

Results of Operations (Continued)

Three months ended March 31, 2005 and 2004

      Net  income  for the  first  quarter  of 2005  amounted  to  $931,000,  an
improvement  of 53.6% or  $325,000  over net  income of  $606,000  for the first
quarter of 2004. The improvement for the first quarter of 2005 was primarily due
to higher gross margin dollars as a result of significant growth in professional
employer ("PEO") services business,  partially offset by higher selling, general
and administrative expenses. Diluted earnings per share for the first quarter of
2005 was $.15  compared to $.10 for the  comparable  2004 period.  The Company's
improved  operating  results  continue  to  reflect,  in part,  the  competitive
advantage  of  offering  a broad  array of human  resource  management  services
through its PEO arrangements. This competitive advantage has enabled the Company
to significantly increase its business opportunities in California.  The Company
expects  this  favorable  trend  to  continue  into  the   foreseeable   future,
particularly in California.

      Revenues for the first quarter of 2005 totaled $49.2 million,  an increase
of approximately $8.6 million or 21.2%, which reflects significant growth in the
Company's  PEO  service  fee  revenue,  combined  with an  increase  in staffing
services revenue.

      PEO service  fee revenue  increased  approximately  $5.1  million or 32.7%
primarily due to increased demand for the Company's broad array of competitively
priced  human  resource  management  services  that  satisfy  customers'  needs.
Management  believes that the favorable  trend in PEO revenues will continue for
the foreseeable future.

      Staffing  services revenue increased  approximately  $3.5 million or 13.9%
over the comparable 2004 quarter primarily due to improved  economic  conditions
for such  services  in the  majority  of areas in which  the  Company  operates.
Management  expects demand for the Company's  staffing services will continue to
reflect overall economic conditions in its market areas.

      Gross  margin for the first  quarter of 2005  totaled  approximately  $7.6
million,  which  represented an increase of $0.9 million or 13.4% over the first
quarter of 2004,  primarily  due to the 21.2%  increase in  revenues.  The gross
margin percent decreased from 16.6% of revenues for the first quarter of 2004 to
15.4% for the first quarter of 2005. The decrease in the gross margin percentage
was due to higher  payroll  taxes and  benefits  and  slightly  higher  workers'
compensation  expense,  offset  in part  by  lower  direct  payroll  costs,  all
expressed as a percent of revenues.  The increase in payroll taxes and benefits,
as a percentage  of revenues,  from 28.4% for the first quarter of 2004 to 31.9%
for the first quarter of 2005,  was due to the effect of  significant  growth in
PEO services and to slightly higher  statutory state  unemployment  tax rates in
various states in which the Company operates as compared to the first quarter of
2004. Workers'  compensation  expense for the first quarter of 2005 totaled $4.9
million,  which  compares  to $4.0  million for the first  quarter of 2004.  The
increase in workers'  compensation  expense was  generally  due to an  increased
provision for the future estimated costs of existing  claims,  as well as to the
effect from increased business activity in California, where injury claims

         of Operations (Continued)

Results of Operations (Continued)

Three months ended March 31, 2005 and 2004 (Continued)

are more costly as compared to other states in which the Company  operates.  The
decline in direct payroll costs, as a percentage of revenues, from 45.1% for the
first  quarter of 2004 to 42.7% for the first quarter of 2005 reflects the shift
in the relative mix of services to the Company's customer base and the effect of
each customer's unique mark-up percent.

      Selling,  general  and  administrative  ("SG&A")  expenses  for the  first
quarter of 2005  amounted to  approximately  $5.9  million,  an increase of $0.4
million or 7.3% over the first  quarter  of 2004.  The  increase  over the first
quarter of 2004 was  primarily  attributable  to increases in branch  management
personnel  and  related  expenses  as a result of growth  in the  Company's  PEO
business.  SG&A expenses,  as a percent of revenues,  declined from 13.6% in the
first quarter of 2004 to 12.0% in the first quarter of 2005.

Factors Affecting Quarterly 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 statutory 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 may fluctuate  from
quarter to quarter  primarily due to the impact of  seasonality  on its staffing
services  business  and on certain of its PEO clients in the  agriculture,  food
processing 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 tend to represent a smaller percentage of revenues and direct
payroll later in the Company's  fiscal year as federal and state  statutory wage
limits  for  unemployment  and  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 and the estimated
future costs of such claims.  Adverse loss  development  of prior period  claims
during  a  subsequent  quarter  may also  contribute  to the  volatility  in the
Company's estimated workers' compensation expense.

Liquidity and Capital Resources

      The Company's cash position of $20,667,000 at March 31, 2005, increased by
$8,514,000  over December 31, 2004,  which  compares to a decrease of $1,723,000
for the  comparable  period in 2004.  The increase in cash at March 31, 2005, as
compared  to  December  31,  2004,  was  primarily  due to net cash  provided by
operating activities.

      Net cash provided by operating activities for the three months ended March
31, 2005 amounted to  $8,168,000,  as compared to net cash provided by operating
activities of $5,471,000  for the comparable  2004 period.  For the three months
ended March 31, 2005, cash flow was provided by net income of $931,000, together
with increases in accrued payroll and related  benefits of $13,819,000 and other
accrued liabilities of $1,599,000 and increases in

workers'  compensation  claims  liabilities  and safety  incentives  liabilities

of $7,128,000  for the similar 2004 period.  For the 2005 period,  the principal
uses  of  cash  for  investing  activities  were  net  purchases  of  restricted
marketable securities of $455,000, purchases of equipment of $151,000, offset in
part by net proceeds totaling $487,000 from maturities of restricted  marketable
securities.  The transactions related to restricted  marketable  securities were
scheduled  maturities and the related  replacement of such  securities  held for
workers'  compensation  surety deposit  purposes.  The Company  presently has no
material long-term capital commitments.

      Net cash provided by financing activities for the three-month period ended
March 31, 2005 was $529,000 compared to net cash used in financing activities of
$66,000 for the similar 2004 period.  For the 2005 period,  the principal source
of cash from  financing  activities  was $766,000 in proceeds  from  exercise of
stock options and the related tax benefit of stock option  exercises,  partially
offset by payments on long-term debt of $237,000.

      The Company's  business strategy  continues to focus on growth through the
expansion  of  operations  at  existing  offices,  together  with the  selective
acquisition  of additional  personnel-related  businesses,  both in its existing
markets  and  other  strategic  geographic  markets.  The  Company  periodically
evaluates proposals for various acquisition  opportunities,  but there can be no
assurance that any additional transactions will be consummated.  As disclosed in
Note 4 to the consolidated  financial  statements  included in this report,  the
Company acquired certain assets of Skills Resource  Training Center ("SRTC"),  a
staffing services company  headquartered in Central Washington state,  effective
January  1,  2004.  As  consideration  for the  acquisition,  the  Company  paid
$3,000,000 in cash and agreed to issue up to 135,731 shares of its common stock,
with the actual  number of shares to be issued based upon the level of financial
performance  achieved by the SRTC offices  during  calendar  year 2004.  Certain
contingencies remain unresolved,  precluding a final calculation of shares to be
issued.  The Company has,  however,  recorded  estimated total Earnout Shares of
52,800 with a value of $778,000 on its consolidated balance sheet as of December
31, 2004.

      The Company entered into a new Credit  Agreement (the "Credit  Agreement")
with its principal bank effective March 31, 2004. The Credit Agreement  provides
for a  revolving  credit  facility  of up to  $6.0  million,  which  includes  a
subfeature  under the line of credit for standby  letters of credit for not more
than $4.0  million.  The  interest  rate on  advances,  if any,  will be, at the
Company's  discretion,  either  (i) equal to the prime  rate or (ii)  LIBOR plus
1.50%. The Credit Agreement expires July 1, 2005.

      The revolving credit facility is  collateralized  by the Company's assets,
including, without limitation, its accounts receivable,  equipment, intellectual
property  and bank  deposits,  and may be prepaid at any time  without  penalty.
Pursuant to the Credit Agreement, the Company is required to maintain compliance
with the following financial covenants: (1) a Current Ratio not

less than 1.10 to 1.0 with  "Current  Ratio"  defined  as total  current  assets
divided by total  current  liabilities;  (2) Tangible Net Worth not less than $8
million,  determined  at each fiscal  quarter  end,  with  "Tangible  Net Worth"
defined as the aggregate of total  stockholders'  equity plus  subordinated debt
less any intangible assets; (3) Total Liabilities  divided by Tangible Net Worth
not greater than 5.00 to 1.0, determined at each fiscal quarter end, with "Total
Liabilities"  defined as the aggregate of current  liabilities  and  non-current
liabilities,  less subordinated debt and the deferred gain on the Company's sale
and leaseback  transaction,  and with "Tangible Net Worth" as defined above; and
(4) net income after taxes not less than $1.00 on an annual basis, determined as
of each fiscal year end,  and pre-tax  profit not less than $1.00 on a quarterly
basis,  determined as of each fiscal  quarter end. The Company was in compliance
with all covenants at March 31, 2005.

      Management expects that current liquid assets, the funds anticipated to be
generated from  operations,  and credit available under the Credit Agreement and
other  potential  sources of  financing,  will be sufficient in the aggregate to
fund the Company's working capital needs for the foreseeable future.  Management
anticipates  that the  Company  will  renew its  credit  arrange-ments  with its
principal Bank on or before July 1, 2005 on terms and  conditions  which will be
not less favorable than those of the current Credit Agreement.

Stock Repurchase Program

      During  1999,  the  Company's  board  of  directors   authorized  a  stock
repurchase  program to repurchase common shares from time to time in open market
purchases.  From  time to time,  since  inception,  the board of  directors  has
approved  increases  in the total number of shares or dollars  authorized  to be
repurchased  under the program.  As of May 11, 2005, the repurchase  program had
remaining  authorized  availability of $443,800 for the repurchase of additional
shares.  The Company made no share repurchases  during the first three months of
2005.  Since the inception of the repurchase  program  through May 11, 2005, the
Company has  repurchased  2,053,555  shares for an aggregate price of $9,187,200
and an average price of $4.47 per share. Management anticipates that the capital
necessary to continue this program will be provided by existing  cash  balances,
cash generated from operations and other available resources.

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.

Forward-Looking Information (Continued)

allowance for doubtful accounts,  the effectiveness of the Company's  management
information  systems,  and the  availability of financing and working capital to
meet the Company's funding requirements,  are forward-looking  statements within
the  meaning of the  Private  Securities  Litigation  Reform  Act of 1995.  Such
forward-looking  statements  involve known and unknown risks,  uncertainties and
other factors that may cause the actual results,  performance or achievements of
the Company or  industry to be  materially  different  from any future  results,
performance  or  achievements  expressed  or  implied  by  such  forward-looking
statements.  Such  factors  with  respect to the  Company  include  difficulties
associated with integrating  acquired  businesses and clients into the Company's
operations,  economic trends in the Company's service areas, material deviations
from expected future workers' compensation claims experience,  collectibility of
accounts  receivable,  the  carrying  values of  deferred  income tax assets and
goodwill,  which may be affected by the Company's future operating results,  the
availability  of capital or letters of credit  necessary to meet  state-mandated
surety deposit  requirements for maintaining the Company's status as a qualified
self-insured employer for workers' compensation  coverage,  and the availability
of and costs  associated  with  potential  sources  of  financing.  The  Company
disclaims any obligation to update any such factors or to publicly  announce the
result  of any  revisions  to any of the  forward-looking  statements  contained
herein to reflect future events or developments.


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 March  31,  2005,  the  Company  had  interest-bearing  debt  obligations  of
approximately $1.6 million,  of which  approximately $1.4 million bears interest
at a variable rate and  approximately  $0.2 million at a fixed rate of interest.
The  variable  rate debt is  comprised  of a $1.475  million note payable with a
10-year term, which bears interest at the three-month  LIBOR rate plus 240 basis
points.  Based on the Company's  overall interest  exposure at March 31, 2005, a
100 basis  point  increase  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 March 31, 2005, the Company had not entered into any interest
rate instruments to reduce its exposure to interest rate risk.


Item 4.  Controls and Procedures

      The Company carried out an evaluation,  under the supervision and with the
participation  of  the  Company's  management,  including  the  Company's  Chief
Executive  Officer and Chief  Financial  Officer,  of the  effectiveness  of the
Company's disclosure controls and procedures,  as defined in Rules 13a-15(e) and
15d-15(e) of the Securities Exchange Act of 1934. Based on that evaluation,  the
Chief  Executive  Officer and Chief  Financial  Officer have  concluded that the
Company's disclosure controls and procedures as of March 31, 2005 were effective
in providing a reasonable  level of assurance  that  information  required to be
disclosed  by the  Company  in  reports  that it  files  or  submits  under  the
Securities Exchange Act of 1934 is recorded, processed,  summarized and reported
within the time periods  specified in the Securities  and Exchange  Commission's
rules and forms.

Item 4.  Controls and Procedures (Continued)

      There were no changes in the Registrant's  internal control over financial
reporting  that  occurred  during the  quarter  ended  March 31,  2005 that have
materially  affected,  or  are  reasonably  likely  to  materially  affect,  the
Registrant's internal control over financial reporting.
