garnishment or the appointment of a receiver, from a court of competent
jurisdiction before, after or during the pendency of any arbitration or other
proceeding. The exercise of any such remedy shall not waive the right of any
party to compel arbitration hereunder.

(d) Arbitrator Qualifications and Powers; Awards. Arbitrators must be
active members of the Oregon State Bar or retired judges of the state or federal
judiciary of Oregon, with expertise in the substantive law applicable to the
subject matter of the Dispute. Arbitrators are empowered to resolve Disputes by
summary rulings in response to motions filed prior to the final arbitration
hearing. Arbitrators (i) shall resolve all Disputes in accordance with the
substantive law of the State of Oregon, (ii) may grant any remedy or relief that
a court of the State of Oregon could order or grant within the scope hereof and
such ancillary relief as is necessary to make effective any award, and (iii)
shall have the power to award recovery of all costs and fees, to impose
sanctions and to take such other actions as they deem necessary to the same
extent a judge could pursuant to the Federal Rules of Civil Procedure, the
Oregon Rules of Civil Procedure or other applicable law. Any Dispute in which
the amount in controversy is $5,000,000 or less shall be decided by a single
arbitrator who shall not render an award of greater than $5,000,000 (including
damages, costs, fees and expenses). By submission to a single arbitrator, each
party expressly waives any right or claim to recover more than $5,000,000. Any
Dispute in which the amount in controversy exceeds $5,000,000 shall be decided
by majority vote of a panel of three arbitrators; provided however, that all
three arbitrators must actively participate in all hearings and deliberations.

(e) Miscellaneous. To the maximum extent practicable, the AAA, the
arbitrators and the parties shall take all action required to conclude any
arbitration proceeding within 180 days of the filing of the Dispute with the
AAA. No arbitrator or other party to an arbitration proceeding may disclose the
existence, content or results thereof, except for disclosures of information by
a party required in the ordinary course of its business, by applicable law or
regulation, or to the extent necessary to exercise any judicial review rights
set forth herein. If more than one

agreement for arbitration by or between the parties potentially applies to a
Dispute, the arbitration provision most directly related to the Loan Documents
or the subject matter of the Dispute shall control. This arbitration provision
shall survive termination, amendment or expiration of any of the Loan Documents
or any relationship between the parties.

UNDER OREGON LAW, MOST AGREEMENTS, PROMISES AND COMMITMENTS MADE BY BANK AFTER
OCTOBER 3, 1989 CONCERNING LOANS AND OTHER CREDIT EXTENSIONS WHICH ARE NOT FOR
PERSONAL, FAMILY OR HOUSEHOLD PURPOSES OR SECURED SOLELY BY THE BORROWER'S
RESIDENCE MUST BE IN WRITING, EXPRESS CONSIDERATION AND BE SIGNED BY BANK TO BE
ENFORCEABLE.

Your acknowledgment of this letter shall constitute acceptance of the
foregoing terms and conditions. Bank's commitment to extend any credit to
Borrower pursuant to the terms of this letter shall terminate on June 30, 2000,
unless this letter is acknowledged by Borrower and returned to Bank on or before
that date.

REVOLVING LINE OF CREDIT NOTE

$15,000,000.00 Portland, Oregon
May 31, 2000

FOR, VALUE RECEIVED, the undersigned BARRETT BUSINESS SERVICES, INC.
("Borrower") promises to pay to the order of WELLS FARGO BANK, NATIONAL
ASSOCIATION ("Bank") at its office at 1300 S. W. Fifth Avenue, T-13, Portland,
Oregon, or at such other place as the holder hereof may designate, in lawful
money of the United States of America and in immediately available funds, the
principal sum of Fifteen Million Dollars ($15,000,000.00), or so much thereof as
may be advanced thereon, to be computed on each advance from the date of its
disbursement as set forth herein.

DEFINITIONS:

As used herein, the following terms shall have the meanings set forth
after each, and any other term defined in this Note shall have the meaning set
forth at the place defined:

(a) "Business Day" means any day except a Saturday, Sunday or any other
day on which commercial banks in Oregon are authorized or required by law to
close.

(b) "Federal Funds Rate" means, for any period, a fluctuating interest
rate per annum equal for each day during such period to the weighted average of
the rates on overnight Federal funds transactions with members of the Federal
Reserve System arranged by Federal funds brokers, as published for such day (or,
if such day is not a Business Day, for the next preceding Business Day) by the
Federal Reserve Bank of New York, or, if such rate is not so published for any
day which is a Business Day, the average of the quotations of such rates on such
day received by Bank from three Federal funds brokers of recognized standing
selected by it.

(c) "Fixed Rate Term" means a period commencing on a Business Day and
continuing for one (1), two (2), or three (3) months, as designated by Borrower,
during which all or a portion of the outstanding principal balance of this Note
bears interest determined in relation to LIBOR; provided however, that no Fixed
Rate Term may be selected for a principal amount less than Five Hundred Thousand
Dollars ($500,000.00); and provided further, that no Fixed Rate Term shall
extend beyond the scheduled maturity date hereof. If any Fixed Rate Term would
end on a day which is not a Business Day, then such Fixed Rate Term shall be
extended to the next succeeding Business Day.

-1-

(d) "LIBOR" means the rate per annum (rounded upward, if necessary, to
the nearest whole 1/8 of 1%) and determined pursuant to the following formula:

LIBOR = Base LIBOR
-------------------------------
100% - LIBOR Reserve Percentage

(i) "Base LIBOR" means the rate per annum for United States dollar
deposits quoted by Bank as the Inter-Bank Market Offered Rate, with the
understanding that such rate is quoted by Bank for the purpose of calculating
effective rates of interest for loans making reference thereto, on the first day
of a Fixed Rate Term for delivery of funds on said date for a period of time
approximately equal to the number of days in such Fixed Rate Term and in an
amount approximately equal to the principal amount to which such Fixed Rate Term
applies. Borrower understands and agrees that Bank may base its quotation of the
Inter-Bank Market Offered Rate upon such offers or other market indicators of
the Inter-Bank Market as Bank in its discretion deems appropriate including, but
not limited to, the rate offered for U.S. dollar deposits on the London
Inter-Bank Market.

(ii) "LIBOR Reserve Percentage" means the reserve percentage prescribed
by the Board of Governors of the Federal Reserve System (or any successor) for
"Eurocurrency Liabilities" (as defined in Regulation D of the Federal Reserve
Board, as amended), adjusted by Bank for expected changes in such reserve
percentage during the applicable Fixed Rate Term.

(e) "Prime Rate" means at any time the rate of interest most recently
announced within Bank at its principal office as its Prime Rate, with the
understanding that the Prime Rate is one of Bank's base rates and serves as the
basis upon which effective rates of interest are calculated for those loans
making reference thereto, and is evidenced by the recording thereof after its
announcement in such internal publication or publications as Bank may designate.

INTEREST:

(a) Interest. The outstanding principal balance of this Note shall bear
interest (computed on the basis of a 360-day year, actual days elapsed) either
(i) at a fluctuating rate per annum equal to the Prime Rate in effect from time
to time, (ii) at a fluctuating rate per annum one and one-quarter percent
(1.25%) above the Federal Funds Rate in effect from time to time, or (iii) at a
fixed rate per annum determined by Bank to be one percent (1.00%) above LIBOR in
effect on the first day of the applicable Fixed Rate Term. When interest is
determined in relation to the Prime Rate or Federal Funds Rate, each change in
the rate of interest hereunder shall become effective on the date each Prime
Rate or Federal Funds Rate change is announced within Bank. With respect to each
LIBOR selection hereunder, Bank is

-2-

hereby authorized to note the date, principal amount, interest rate and Fixed
Rate Term applicable thereto and any payments made thereon on Bank's books and
records (either manually or by electronic entry) and/or on any schedule attached
to this Note, which notations shall be prima facie evidence of the accuracy of
the information noted.

(b) Selection of Interest Rate Options. At any time any portion of this
Note bears interest determined in relation to LIBOR, it may be continued by
Borrower at the end of the Fixed Rate Term applicable thereto so that all or a
portion thereof bears interest determined in relation to the Prime Rate, to the
Federal Funds Rate, or to LIBOR for a new Fixed Rate Term designated by
Borrower. At any time any portion of this Note bears interest determined in
relation to the Prime Rate or to the Federal Funds Rate, Borrower may convert
all or a portion thereof so that it bears interest determined in relation to
LIBOR for a Fixed Rate Term designated by Borrower. At such time as Borrower
requests an advance hereunder or wishes to select a LIBOR option for all or a
portion of the outstanding principal balance hereof, and at the end of each
Fixed Rate Term, Borrower shall give Bank notice specifying: (i) the interest
rate option selected by Borrower; (ii) the principal amount subject thereto; and
(iii) for each LIBOR selection, the length of the applicable Fixed Rate Term.
Any such notice may be given by telephone so long as, with respect to each LIBOR
selection, (A) Bank receives written confirmation from Borrower not later than
three (3) Business Days after such telephone notice is given, and (B) such
notice is given to Bank prior to 10:00 a.m., California time, on the first day
of the Fixed Rate Term. For each LIBOR option requested hereunder, Bank will
quote the applicable fixed rate to Borrower at approximately 10:00 a.m.,
California time, on the first day of the Fixed Rate Term. If Borrower does not
immediately accept the rate quoted by Bank, any subsequent acceptance by
Borrower shall be subject to a redetermination by Bank of the applicable fixed
rate; provided however, that if Borrower fails to accept any such rate by 11:00
a.m., California time, on the Business Day such quotation is given, then the
quoted rate shall expire and Bank shall have no obligation to permit a LIBOR
option to be selected on such day. If no specific designation of interest is
made at the time any advance is requested hereunder or at the end of any Fixed
Rate Term, Borrower shall be deemed to have made a Federal Funds Rate interest
selection for such advance or the principal amount to which such Fixed Rate Term
applied.

(c) Additional LIBOR Provisions.

(i) If Bank at any time shall determine that for any reason adequate and
reasonable means do not exist for ascertaining LIBOR, then Bank shall promptly
give notice thereof to Borrower. If such notice is given and until such notice
has been withdrawn by Bank, then (A) no new LIBOR option may be selected by
Borrower, and (B) any portion of the outstanding principal

-3-

balance hereof which bears interest determined in relation to LIBOR, subsequent
to the end of the Fixed Rate Term applicable thereto, shall bear interest
determined in relation to the Prime Rate.

(ii) If any law, treaty, rule, regulation or determination of a court or
governmental authority or any change therein or in the interpretation or
application thereof (each, a "Change in Law") shall make it unlawful for Bank
(A) to make LIBOR options available hereunder, or (B) to maintain interest rates
based on LIBOR, then in the former event, any obligation of Bank to make
available such unlawful LIBOR options shall immediately be cancelled, and in the
latter event, any such unlawful LIBOR-based interest rates then outstanding
shall be converted, at Bank's option, so that interest on the portion of the
outstanding principal balance subject thereto is determined in relation to the
Prime Rate; provided however, that if any such Change in Law shall permit any
LIBOR-based interest rates to remain in effect until the expiration of the Fixed
Rate Term applicable thereto, then such permitted LIBOR-based interest rates
shall continue in effect until the expiration of such Fixed Rate Term. Upon the
occurrence of any of the foregoing events, Borrower shall pay to Bank
immediately upon demand such amounts as may be necessary to compensate Bank for
any fines, fees, charges, penalties or other costs incurred or payable by Bank
as a result thereof and which are attributable to any LIBOR options made
available to Borrower hereunder, and any reasonable allocation made by Bank
among its operations shall be conclusive and binding upon Borrower.

(iii) If any Change in Law or compliance by Bank with any request or
directive (whether or not having the force of law) from any central bank or
other governmental authority shall:

(A) subject Bank to any tax, duty or other charge with respect to any
LIBOR options, or change the basis of taxation of payments to
Bank of principal, interest, fees or any other amount payable
hereunder (except for changes in the rate of tax on the overall
net income of Bank); or

(B) impose, modify or hold applicable any reserve, special deposit,
compulsory loan or similar requirement against assets held by,
deposits or other liabilities in or for the account of, advances
or loans by, or any other acquisition of funds by any office of
Bank; or

(C) impose on Bank any other condition;

and the result of any of the foregoing is to increase the cost to Bank of
making, renewing or maintaining any LIBOR options hereunder and/or to reduce any
amount receivable by Bank in connection therewith, then in any such case,
Borrower shall pay to Bank immediately upon demand such amounts as may be
necessary

-4-

to compensate Bank for any additional costs incurred by Bank and/or reductions
in amounts received by Bank which are attributable to such LIBOR options. In
determining which costs incurred by Bank and/or reductions in amounts received
by Bank are attributable to any LIBOR options made available to Borrower
hereunder, any reasonable allocation made by Bank among its operations shall be
conclusive and binding upon Borrower.

(d) Payment of Interest. Interest accrued on this Note shall be payable
on the first day of each month, commencing July 1, 2000.

(e) Default Interest. From and after the maturity date of this Note, or
such earlier date as all principal owing hereunder becomes due and payable by
acceleration or otherwise, the outstanding principal balance of this Note shall
bear interest until paid in full at an increased rate per annum (computed on the
basis of a 360-day year, actual days elapsed) equal to four percent (4%) above
the rate of interest from time to time applicable to this Note.

BORROWING AND REPAYMENT:

(a) Borrowing and Repayment. Borrower may from time to time during the
term of this Note borrow, partially or wholly repay its outstanding borrowings,
and reborrow, subject to all of the limitations, terms and conditions of this
Note and of any document executed in connection with or governing this Note;
provided however, that the total outstanding borrowings under this Note shall
not at any time exceed the principal amount stated above. The unpaid principal
balance of this obligation at any time shall be the total amounts advanced
hereunder by the holder hereof less the amount of principal payments made hereon
by or for any Borrower, which balance may be endorsed hereon from time to time
by the holder. The outstanding principal balance of this Note shall be due and
payable in full on May 31, 2001.

(b) Advances. Advances hereunder, to the total amount of the principal
sum stated above, may be made by the holder at the oral or written request of
(i) William W. Sherertz, Jr. or Michael D. Mulholland, any one acting alone, who
are authorized to request advances and direct the disposition of any advances
until written notice of the revocation of such authority is received by the
holder at the office designated above, or (ii) any person, with respect to
advances deposited to the credit of any account of any Borrower with the holder,
which advances, when so deposited, shall be conclusively presumed to have been
made to or for the benefit of each Borrower regardless of the fact that persons
other than those authorized to request advances may have authority to draw
against such account. The holder shall have no obligation to determine whether
any person requesting an advance is or has been authorized by any Borrower.

-5-

(c) Application of Payments. Each payment made on this Note shall be
credited first, to any interest then due and second, to the outstanding
principal balance hereof. All payments credited to principal shall be applied
first, to the outstanding principal balance of this Note which bears interest
determined in relation to the Prime Rate and/or Federal Funds Rate, if any, and
second, to the outstanding principal balance of this Note which bears interest
determined in relation to LIBOR, with such payments applied to the oldest Fixed
Rate Term first.

PREPAYMENT:

(a) Prime Rate/Federal Funds Rate. Borrower may prepay principal on any
portion of this Note which bears interest determined in relation to the Prime
Rate or Federal Funds Rate at any time, in any amount and without penalty.

(b) LIBOR. Borrower may prepay principal on any portion of this Note
which bears interest determined in relation to LIBOR at any time and in the
minimum amount of Five Hundred Thousand Dollars ($500,000.00); provided however,
that if the outstanding principal balance of such portion of this Note is less
than said amount, the minimum prepayment amount shall be the entire outstanding
principal balance thereof. In consideration of Bank providing this prepayment
option to Borrower, or if any such portion of this Note shall become due and
payable at any time prior to the last day of the Fixed Rate Term applicable
thereto by acceleration or otherwise, Borrower shall pay to Bank immediately
upon demand a fee which is the sum of the discounted monthly differences for
each month from the month of prepayment through the month in which such Fixed
Rate Term matures, calculated as follows for each such month:

(i) Determine the amount of interest which would have accrued each
month on the amount prepaid at the interest rate applicable to
such amount had it remained outstanding until the last day of the
Fixed Rate Term applicable thereto.

(ii) Subtract from the amount determined in (i) above the amount of
interest which would have accrued for the same month on the
amount prepaid for the remaining term of such Fixed Rate Term at
LIBOR in effect on the date of prepayment for new loans made for
such term and in a principal amount equal to the amount prepaid.

(iii) If the result obtained in (ii) for any month is greater than
zero, discount that difference by LIBOR used in (ii) above.

Each Borrower acknowledges that prepayment of such amount may result in Bank
incurring additional costs, expenses and/or liabilities, and that it is
difficult to ascertain the full

-6-

extent of such costs, expenses and/or liabilities. Each Borrower, therefore,
agrees to pay the above-described prepayment fee and agrees that said amount
represents a reasonable estimate of the prepayment costs, expenses and/or
liabilities of Bank. If Borrower fails to pay any prepayment fee when due, the
amount of such prepayment fee shall thereafter bear interest until paid at a
rate per annum two percent (2%) above the Prime Rate in effect from time to time
(computed on the basis of a 360-day year, actual days elapsed). Each change in
the rate of interest on any such past due prepayment fee shall become effective
on the date each Prime Rate change is announced within Bank.

EVENTS OF DEFAULT:

The occurrence of any of the following shall constitute an "Event of
Default" under this Note:

(a) The failure to pay any principal, interest, fees or other charges
when due hereunder or under any contract, instrument or document executed in
connection with this Note.

(b) The filing of a petition by or against any Borrower, any guarantor
of this Note or any general partner or joint venturer in any Borrower which is a
partnership or a joint venture (with each such guarantor, general partner and/or
joint venturer referred to herein as a "Third Party Obligor") under any
provisions of the Bankruptcy Reform Act, Title 11 of the United States Code, as
amended or recodified from time to time, or under any similar or other law
relating to bankruptcy, insolvency, reorganization or other relief for debtors;
the appointment of a receiver, trustee, custodian or liquidator of or for any
part of the assets or property of any Borrower or Third Party Obligor; any
Borrower or Third Party Obligor becomes insolvent, makes a general assignment
for the benefit of creditors or is generally not paying its debts as they become
due; or any attachment or like levy on any property of any Borrower or Third
Party Obligor.

(c) The dissolution or liquidation of any Borrower which is a
corporation, partnership, joint venture or other types of entity.

(d) Any default in the payment or performance of any obligation, or any
defined event of default, under any provisions of any contract, instrument or
document pursuant to which any Borrower or Third Party Obligor has incurred any
obligation for borrowed money, any purchase obligation, or any other liability
of any kind to any person or entity, including the holder; provided, however,
that any cure period applicable to such default has expired, and with respect to
a default under any obligation to any person or entity other than Bank, the
amount of the debt or other liability in default exceeds $5,000,000.00.

-7-

(e) Any financial statement provided by any Borrower or Third Party
Obligor to Bank proves to be incorrect, false or misleading in any material
respect.

(f) Any sale or transfer of all or a substantial or material part of the
assets of any Borrower or Third Party Obligor other than in the ordinary course
of its business.

(g) Any violation or breach of any provision of, or any defined event of
default under, any addendum to this Note or any loan agreement, guaranty,
security agreement, deed of trust, mortgage or other document executed in
connection with or securing this Note, which, if such violation or breach is
curable, is not cured within the earlier to occur of (i) 30 days after the
occurrence thereof or (ii) any applicable cure period expressly provided in such
document.

MISCELLANEOUS:

(a) Remedies. Upon the occurrence of any Event of Default, the holder of
this Note, at the holder's option, may declare all sums of principal and
interest outstanding hereunder to be immediately due and payable without
presentment, demand, notice of nonperformance, notice of protest, protest or
notice of dishonor all of which are expressly waived by each Borrower, and the
obligation, if any, of the holder to extend any further credit hereunder shall
immediately cease and terminate. Each Borrower shall pay to the holder
immediately upon demand the full amount of all payments, advances, charges,
costs and expenses, including reasonable attorneys' fees (to include outside
counsel fees and all allocated costs of the holder's in-house counsel), expended
or incurred by the holder in connection with the enforcement of the holder's
rights and/or the collection of any amounts which become due to the holder under
this Note, and the prosecution or defense of any action in any way related to
this Note, including without limitation, any action for declaratory relief,
whether incurred at the trial or appellate level, in an arbitration proceeding
or otherwise, and including any of the foregoing incurred in connection with any
bankruptcy proceeding (including without limitation, any adversary proceeding,
contested matter or motion brought by Bank or any other person) relating to any
Borrower or any other person or entity.

(b) Obligations Joint and Several. Should more than one person or entity
sign this Note as a Borrower, the obligations of each such Borrower shall be
joint and several.

(c) Governing Law. This Note shall be governed by and construed in
accordance with the laws of the State of Oregon.

UNDER OREGON LAW, MOST AGREEMENTS, PROMISES AND COMMITMENTS MADE BY BANK AFTER
OCTOBER 3, 1989 CONCERNING LOANS AND OTHER CREDIT EXTENSIONS WHICH ARE NOT FOR
PERSONAL, FAMILY OR HOUSEHOLD

PURPOSES OR SECURED SOLELY BY THE BORROWER'S RESIDENCE MUST BE IN WRITING,
