EMPLOYMENT AGREEMENT
                              --------------------


         THIS EMPLOYMENT  AGREEMENT,  dated for reference  purposes  January 26,
1999, is by and between BARRETT BUSINESS SERVICES,  INC., a Maryland corporation
("Employer"),  and  MICHAEL  D.  MULHOLLAND  ("Employee").  Employer  desires to
confirm the continued employment of Employee as its Vice  President-Finance  and
Secretary,  to perform the duties set forth in this  Agreement;  and Employee is
willing to enter into this contract of employment.

         NOW, THEREFORE, in consideration of the mutual promises, agreements and
conditions hereinafter set forth, it is agreed as follows:

         1. EMPLOYMENT. Employer shall continue to employ Employee, and Employee
agrees to be employed by Employer in  accordance  with the terms and  conditions
hereinafter  set forth.  Employee  represents and warrants that he has the legal
capacity to execute and perform this  Agreement,  that it is a valid and binding
agreement  against  him  according  to its  terms,  and that its  execution  and
performance  by him does not  violate  the terms of any  existing  agreement  or
understanding to which Employee is a party. In addition, Employee represents and
warrants  that  he  knows  of no  reason  why he is not  physically  capable  of
performing his obligations under this Agreement in accordance with its terms.

         2. TERM.  The term of this  Agreement  will begin on January 26,  1999,
1999 ("Anniversary Date"). Except as otherwise provided under paragraphs 2.1 and
2.2 herein, as of each Anniversary Date, the term of this Agreement shall not be
less than two (2) years.

              2.1 Unless  either party to this  Agreement  notifies the other in
writing  not later than 30 days prior to an  Anniversary  Date of an election to
terminate this Agreement on the Anniversary Date in the following year, the term
of this Agreement shall  automatically renew each year for an additional one (1)
year,  upon the annual  Anniversary  Date,  such that the effective term of this
Agreement  shall  always be not less  than two (2) years as of each  Anniversary
Date.

              2.2 In the event of a "Change in  Control" of the  Employer,  this
Agreement shall  automatically renew for a period of not less than two (2) years
beginning with the day immediately preceding the effective date of the Change in
Control of the Employer.  For the purposes of this Agreement,  Change in Control
shall be  identical  to the  definition  included in the  Employer's  1993 Stock
Incentive  Plan,  as amended;  provided,  however,  the  definition of Change in
Control shall not include any form of acquisition,  merger or  consolidation  of
Employer's  stock  initiated by William W. Sherertz or any entity  controlled by
William W. Sherertz which would cause the Employer to become a

Page 1--EMPLOYMENT AGREEMENT


privately owned company and William W. Sherertz continues as President and Chief
Executive Officer.

         3. DUTIES.  Employee will serve as Vice President-Finance and Secretary
of Employer, with such duties as are customarily associated with such positions,
and such other  duties as may be  assigned to him from time to time by the Board
of Directors of Employer (the "Board").

         4. EXTENT OF SERVICES;  RESTRICTIONS.  Employee shall devote his entire
working time,  attention and energies to the performance of his duties hereunder
and shall  not,  during  the term of this  Agreement,  be  engaged  in any other
business  activity,  whether or not such business  activity is pursued for gain,
profit or other pecuniary advantage. Employee shall at all times, faithfully and
to the best of his  ability,  perform  all of the duties that may be required of
him  pursuant  to  this  Agreement;  provided,  however,  that  nothing  in this
Agreement shall preclude Employee from devoting time during  reasonable  periods
required for:

              4.1 serving,  in accordance with Employer's  policies and with the
prior  approval  of the Board,  as a director  or member of a  committee  of any
company or  organization  involving no actual or potential  conflict of interest
with Employer;

              4.2 delivering lectures and fulfilling speaking engagements;

              4.3 engaging in charitable and community activities; and

              4.4  investing  his  personal  assets in  businesses  in which his
participation  is  solely  that of an  investor;  provided,  however,  that such
activities  do not  materially  affect  or  interfere  with the  performance  of
Employee's duties and obligations to Employer.

         5. SALARY.  Employee  shall be paid a salary of $155,000  per year,  in
accordance  with  Employer's  standard  payroll  procedures  for  its  executive
management employees. Employee's salary shall be evaluated annually, as provided
in the Employer's Executive Officer Compensation Policy Dated November 30, 1995.
The foregoing salary is in addition to such other forms of compensation  such as
stock appreciation rights,  options,  bonuses, and benefits,  as provided for in
the Company's Executive Officer Compensation Policy Dated November 30, 1995, and
as the Board may award to Employee from time to time.

         6.  BENEFITS;  REIMBURSEMENT;  STOCK  OPTIONS.  Employer  will  furnish
Employee,  at Employer's  expense,  the same employment fringe benefits that are
generally  provided  from time to time by Employer to its  executive  management
employees.  Employer  shall  reimburse  Employee  for  reasonable  out-of-pocket
expenses that 

Page 2--EMPLOYMENT AGREEMENT


Employee  incurs in connection  with the performance of his duties in accordance
with  the  same  reimbursement  policies  that  generally  apply  to  Employer's
executive management employees.

         7.  TERMINATION.

              7.1 FOR CAUSE. Employer, by a vote of a majority of the Board, may
terminate  Employee's  employment at any time "For Cause" with immediate  effect
upon  delivering  written  notice  thereof to  Employee.  For  purposes  of this
Agreement, For Cause includes:

                   (a) a significant failure to comply with policies,  standards
and regulations of the Employer as established from time to time;

                   (b) gross negligence in the performance of Employee's duties,
continuing after appropriate notice pursuant to Employer policy;

                   (c) embezzlement,  theft,  larceny,  material fraud, or other
acts of dishonesty;

                   (d)  significant  violation  of  any of  Employee's  material
duties or obligations under this Agreement; or

                   (e)  conviction  of or  entry  of a plea  of  guilty  or nolo
contendere to a felony or other crime.

              On termination  For Cause,  Employer shall pay Employee his salary
earned  through the date of  termination,  and Employee shall not be entitled to
any further compensation or benefits under this Agreement after the date of such
termination  other than fringe  benefits due under  Employer's  benefit plans or
applicable law.

              7.2  WITHOUT  CAUSE.  In the event of a Change in  Control  of the
Employer and  Employee's  employment  is terminated  other than For Cause,  then
Employer shall pay to Employee an amount equal to two (2) times his then-current
annual  base  salary  in a lump  sum  within  three  (3)  days  of the  date  of
termination of employment,  unless the provisions of paragraph 8 are applicable,
wherein such lump sum payment shall then be payable in accordance with paragraph
8. If Employee voluntarily terminates employment with Employer within 90 days of
a "Change in Duties" related to a Change in Control, Employer shall be deemed to
have terminated  Employee's employment other than For Cause under this paragraph
7.2,  then  Employer  shall pay to Employee an amount equal to two (2) times his
then-current  annual base salary in a lump sum within three (3) days of the date
of  termination  of  employment,  unless  the  provisions  of  paragraph  8  are
applicable,  wherein such lump sum payable  shall then be payable in  accordance
with paragraph 8. Change in Duties shall mean any one or more of the following:

Page 3--EMPLOYMENT AGREEMENT


                   (a) a significant change in the nature or scope of Employee's
title, responsibilities,  authorities, or duties from those applicable as of the
date of this Agreement;

                   (b) a significant  diminution in  Employee's  eligibility  to
participate in bonus,  stock option,  incentive awards,  and other  compensation
plans;

                   (c) a significant diminution in employee benefits, including,
but not limited to, medical and dental insurance,  and perquisites applicable to
Employee, from the employee benefits and perquisites to which he was entitled as
of the date of this Agreement;  provided, however, Employer may modify and amend
the group benefit plans offered to its  employees  including  Employee,  without
violating the terms of this paragraph 7.2(c);

                   (d) a change in the location of Employee's principal place of
employment by Employer by more than 30 miles from Portland, Oregon; or

                   (e) significant  violation of any of the Employer's  material
duties or obligations under this Agreement.

              7.3 DEATH.  In the event of  Employee's  death  during the term of
this Agreement, this Agreement will terminate.

              7.4  DISABILITY.  This Agreement  shall  terminate upon Employee's
total disability. Employee's total disability means his inability to perform his
regular  duties  by  reason  of  illness  or  accident  for a period  of six (6)
consecutive  months,  determined by a licensed physician  acceptable to Employer
and Employee. On termination by reason of Employee's disability,  in addition to
such group  disability  insurance  benefits as Employer may provide from time to
time,  Employee  and his  dependents  shall  continue to be covered by the group
health insurance provided to executive  management employees of Employer for the
remaining term of this Agreement.

              7.5 BY  EMPLOYEE.  In the event  Employee  voluntarily  terminates
employment  with  Employer  during the term of this  Agreement  (other than as a
result of a Change in Duties as set  forth in  paragraph  7.2  above),  Employer
shall pay Employee his salary through the date of termination and Employee shall
not be entitled to any further  compensation  or benefits  under this  Agreement
after the date of termination  other than fringe  benefits due under  Employer's
benefit plans or applicable law.

         8. LIMITATIONS ON TERMINATION COMPENSATION.

              8.1 In the event that the "Present  Value" (as defined  herein) of
any termination benefits payable to Employee under this Agreement, and any other
payments  otherwise  payable to Employee by the Employer on or after a Change in
Control,  which are deemed under  Section  280G of the Internal  Revenue Code of

Page 4--EMPLOYMENT AGREEMENT


1986, as amended (the "Code"), to constitute "Parachute Payments" [as defined in
Section 280G without regard to Section  280G(b)(2)(A)(ii)] equals or exceeds 300
percent of Employee's base amount (as defined herein),  the provisions set forth
below will apply, and termination benefits payable to Employee under paragraph 7
of this  Agreement  will be  made  only in  accordance  with  this  paragraph  8
notwithstanding any provision to the contrary in this Agreement.

              8.2 Not  later  than ten  (10)  days  from the date of  Employee's
termination,  the Employer will provide  Employee with a schedule  indicating by
category the Present Value of all termination benefits payable to Employee under
this  Agreement  and any other  payments  otherwise  payable to  Employee by the
Employer on or after the Change in Control,  which,  in the Employer's  opinion,
constitute  Parachute Payments under Section 280G. No payments under paragraph 7
of this  Agreement  shall be made until  after ten (10) days from the receipt of
such schedule by Employee.  At any time prior to the expiration of said ten (10)
day  period,  Employee  shall  have the right to select  from all or part of any
category of payment to be made under this Agreement those payments to be made to
Employee  in an amount,  the  Present  Value of which  (when  combined  with the
Present  Value of any  other  payments  otherwise  payable  to  Employee  by the
Employer  that are  deemed  Parachute  Payments)  is less  than 300  percent  of
Employee's  base  amount.  If  Employee  fails to  exercise  his right to make a
selection,  only a lump sum cash termination  payment in the maximum amount that
is less than 300 percent of his base amount (reduced by the Present Value of any
other  payments  otherwise  payable to Employee by the Employer  that are deemed
Parachute Payments) shall be made to Employee on the day after the expiration of
the period  extending ten (10) days from the receipt by Employee of the schedule
provided for hereunder.

              8.3 At any time prior to Employee  exercising  his right to make a
selection under paragraph 8.2, Employee shall have the right to request that the
Employer  obtain a ruling from the Internal  Revenue  Service  ("Service") as to
whether any or all payments  listed on the schedule  provided  hereunder are, in
the view of the Service,  Parachute  Payments under Section 280G. If a ruling is
sought  pursuant to his request,  no  termination  benefit under this  Agreement
shall be paid to him until after 15 days from the date of such  ruling,  and the
period  during which  Employee may exercise his right to make a selection  under
paragraph  8.2 hereof  shall be extended to a date 15 days from the date of such
ruling. For purposes of this paragraph 8, Employee and the Employer hereby agree
to be bound by the Service's ruling as to whether payments constitute  Parachute
Payments under Section 280G. If the Service declines, for any reason, to provide
the ruling requested, the Employer's determination with respect to what payments
constitute  Parachute  Payments  shall  control,  and the  period  during  which
Employee may exercise his right to make a selection  under  paragraph 8.2 hereof
shall  be  

Page 5--EMPLOYMENT AGREEMENT



extended to a date 15 days from the date of the Service's notice indicating that
no ruling will be forthcoming.

              8.4 For purposes of this  paragraph 8,  "Present  Value" means the
value  determined in accordance  with the  principles of Section  1274(d) of the
Code under rules provided in Treasury  Regulations  under Section 280G, and base
amount means the average annual compensation payable to Employee by the Employer
and  includable in his gross income for federal  income tax purposes  during the
shorter of the period  consisting  of the most  recent  five (5)  taxable  years
ending  before the date of any Change in Control of the  Employer or the portion
of such period during which Employee was an employee of the Employer.

              8.5 Any  selection  by  Employee  under this  paragraph 8 shall be
invalid,  and no such payments will be made,  unless,  under  relevant  Treasury
Regulations,  such  payments  can be reduced to Present  Value as of the date of
termination or such  appropriate date prior thereto as provided in said Treasury
Regulations.  

              8.6  References to Section 280G herein are specific  references to
Section  280G,  as amended to date.  In the event that  Section  280G is amended
further prior to expiration or termination of this  Agreement,  or replaced by a
successor statute,  the limitations imposed by this paragraph 8 upon payments to
be made to  Employee  under  this  Agreement  shall be deemed  modified  without
further  action of the parties so as to provide only for such  limitations  that
are consistent with such amendment(s) or successor  statute(s),  as the case may
be. In the event that Section 280G, or any successor statute, is repealed,  this
paragraph 8 shall cease to be  effective on the  effective  date of such repeal.
The parties to this Agreement  recognize that final Treasury  Regulations  under
Section 280G may affect the amounts that may be paid  hereunder  and agree that,
upon issuance of such final Treasury Regulations, this Agreement may be modified
as in good faith deemed  necessary in light of the  provisions  of such Treasury
Regulations to achieve the purposes  hereof,  and consent to such  modifications
shall not be unreasonably withheld.

         9. CONFIDENTIAL INFORMATION AND EMPLOYER MATERIALS. Employee recognizes
and  acknowledges  that all  information  pertaining  to the affairs,  business,
clients,  or  customers  of Employer  (any or all of such  entities  hereinafter
referred to as the "Business"), as such information may exist from time to time,
is confidential  information and is a unique and valuable asset of the Business,
access to and knowledge of which are essential to the  performance of Employee's
duties under this Agreement. Employee shall not, except to the extent reasonably
necessary in the performance of his duties under this Agreement,  divulge to any
person, firm, association,  corporation, or governmental agency, any information
concerning the affairs, business,  clients, or customers of the Business (except
such information as is required by law to be divulged to a government  agency or
pursuant to lawful  process),  or make use of any such  information  for 

Page 6--EMPLOYMENT AGREEMENT


his  own  purposes  or for the  benefit  of any  person,  firm,  association  or
corporation  (except the Business) and shall use his reasonable  best efforts to
prevent  the  disclosure  of  any  such  information  by  others.  All  records,
memoranda,  letters,  books, papers, reports,  accountings,  experience or other
data, and other records and documents relating to the Business,  whether made by
Employee or otherwise coming into his possession,  are confidential  information
and are, shall be, and shall remain the property of Employer.  No copies thereof
shall be made which are not  retained  by  Employer,  and  Employee  agrees,  on
termination of his employment,  or on demand of Employer, to deliver the same to
Employer.  Employer's  obligation to make  payments,  deliver shares of stock or
provide  for any  benefits  under this  Agreement  or any other  agreement  with
Employee  shall cease upon any  violation of the  preceding  provisions  of this
paragraph; provided, however, that Employee shall first have the right to appear
before the Board with  counsel and that  cessation of payments  shall  require a
vote of a majority of the Board.

         10.  NOTICES.  Any notice  required or permitted to be given under this
Agreement shall be sufficient if in writing and personally  delivered or sent by

         16.  ENTIRE  AGREEMENT.  The entire  agreement  between  the parties is
contained herein and it supersedes and replaces all other agreements  pertaining

relating  to  fringe  benefit  plans  provided  to  Employee  or  noncompetition
agreements.  There are no promises or representations made on behalf of Employer
to induce Employee to enter into this Agreement which are not set forth herein.

         17.  ARBITRATION.  Any and all disputes  arising from or  pertaining to

by binding  arbitration in Portland,  Oregon. The arbitration shall be conducted
by an independent  and neutral arbiter  mutually agreed upon by the parties.  If
the parties fail to agree on the  selection of the arbiter  within 30 days after
either party requests arbitration,  the arbiter shall be appointed,  on petition
by either  party,  by the  Presiding  Judge of the Circuit Court of the State of
Oregon for  Multnomah  County.  The fees and  expenses of the  arbiter  shall be
equally  shared by the parties.  The decision of the arbiter  shall be final and
judgment  thereon  may be entered in any court of  competent  jurisdiction.  All
parties shall use good faith best efforts to resolve any dispute related to this
Agreement  within 90 days from the date of notice by either  party of a dispute.
In the event the  Employer  fails to use good faith best  efforts to resolve any
dispute  hereunder  within 90 days,  then the Employer  shall forfeit his rights

judgment in favor of the Employee,  including all fees and expenses  incurred by
the  Employee  in  connection  with  the  dispute,  in any  court  of  competent

         18. NO  ATTACHMENT.  Except as  required  by law,  no right to  receive

alienation, sale, assignment,  encumbrance,  charge, pledge, or hypothecation or
to execution, attachment, levy, or similar process or assignment by operation of
law, and any attempt, voluntary or involuntary,  to effect any such action shall
be  null,  void  and of no  effect;  provided,  however,  that  nothing  in this
paragraph  18  shall  preclude  the  assumption  of such  rights  by  executors,
administrators  or other  legal  representatives  of  Employee or his estate and
their assigning any rights hereunder to the person or persons entitled thereto.

Page 8--EMPLOYMENT AGREEMENT

shall be paid in cash from the general funds of Employer.  Employer shall not be
required to establish a special or separate fund or other  segregation of assets
to assure such payments,  and, if Employer shall make any  investments to aid it
in meeting its  obligations  hereunder,  Employee shall have no right,  title or
interest  whatsoever  in or to any such  investments  except as may otherwise be
expressly   provided  in  a  separate  written   instrument   relating  to  such
investments.  Nothing contained in this Agreement,  and no action taken pursuant
to its  provisions,  shall create or be construed to create a trust of any kind,
or a fiduciary relationship,  between Employer and Employee or any other person.
To the extent that any person acquires a right to receive payments from Employer
hereunder,  such  right  shall  be no  greater  than the  right of an  unsecured
creditor of Employer.
