                   Notes to Consolidated Financial Statements
                                   (Unaudited)

1.   Accounting Policies
     -------------------
     The  unaudited  consolidated  financial  statements  have been  prepared by
     Olsten Corporation (the "Company") pursuant to the rules and regulations of
     the Securities and Exchange  Commission  and, in the opinion of management,
     include all  adjustments  necessary for a fair  presentation  of results of
     operations,  financial  position and cash flows for each period  presented.
     Results for interim periods are not necessarily indicative of results for a
     full year.  The  year-end  balance  sheet  data was  derived  from  audited
     financial  statements,  but does not  include all  disclosures  required by
     generally accepted accounting principles.

2.   Comprehensive Income (Loss)
     ---------------------------
     Total  comprehensive  income amounted to $16 million and comprehensive loss
     was $37 million during the second quarters of 1999 and 1998,  respectively.
     During the six months, total comprehensive loss amounted to $49 million and
     $25 million for 1999 and 1998, respectively.

3.   Acquisitions
     ------------
     Under  the  terms  of  the  1997  purchase  agreement  for  Olsten  Travail
     Temporaire  (formerly Sogica S.A.), an additional  payment of approximately
     $31 million was paid in the second quarter of 1998. An additional  purchase
     price payment will be required in the year 2000,  calculated based upon the
     average net income for the three fiscal years ended 1999.  Such  additional
     payments  relate to the  Company's  original  purchase of 70 percent of the
     Olsten Travail Temporaire shares. The Company is also obligated in the year
     2000 to purchase  the  remaining  30 percent of the shares at a price to be
     determined by a multiple ranging from an upper limit of 16 to a lower limit
     of 10,  applied to the average  net income for the fiscal  years ended 1998
     and 1999.

     During  the first six  months of 1999,  the  Company  purchased  additional
     Staffing  Services  operations in France and Health Services  operations in
     the United States for  approximately  $15 million in cash. All acquisitions
     have been accounted for by the purchase method of accounting.

4.   Special Charges and Adjustments
     -------------------------------
     On March 30, 1999,  the Company  announced  plans to take a special  charge
     aggregating  $102 million.  The charge  provides for the  settlement of two
     federal investigations  focusing on the Company's Medicare home office cost
     reports and certain  transactions  with Columbia/HCA and a provision of $46
     million  for  the   realignment   of  business  units  as  part  of  a  new
     restructuring  plan,  including  compensation  and  severance  costs of $22
     million to be paid to  operational  support  staff,  branch  administrative
     personnel and management,  asset  write-offs of $16 million and integration
     costs  of  $8  million,   primarily  related  to  obligations  under  lease
     agreements for offices and other facilities  being closed.  With respect to
     the  two  federal  investigations,  the  final  civil,  administrative  and
     criminal  agreements  were  finalized  and signed on July 19,  1999 and the
     settlement  amount was paid on August 11,  1999.  The payment was funded by


                                       5
<PAGE>
     the Company's  revolving credit agreement in the amount of $45 million with
     the remainder  coming from operating cash flows.  Asset  write-offs  relate
     primarily  to fixed assets  being  disposed of in offices  being closed and
     facilities  being  consolidated  as  well  as  fixed  assets  and  goodwill
     attributable  to the  Company's  exit from  certain  businesses  previously
     acquired but not within the  Company's  strategic  objectives.  The Company
     expects that the realignment of the business units will achieve a reduction
     of expenses  of  approximately  $14 million for the last three  quarters of
     1999, due to reduced employee, lease and depreciation expenses.


         The Health Services' division represented $73 million of the total
         charge,  inclusive of a provision  for the  settlement  of the two
         government   investigations  of  $56  million,   compensation  and
         severance costs of $5 million,  asset write-offs of $7 million and
         integration costs of $5 million.

         The charge for the Staffing Services' division totaled $16 million
         and related to  business  realignments,  including  $6 million for
         compensation  and severance costs, $8 million for asset write-offs
         and $2 million for integration costs.

         The  balance of the  charge of $13  million  relates to  corporate
         operations and consists  primarily of  compensation  and severance
         costs.

         As of the end of the  first  six  months of 1999,  60  percent  of
         closures and  consolidations of facilities have been completed and
         approximately  70 percent of the 640  expected  terminations  have
         occurred.

     In 1998, as a part of the Balanced  Budget Act, the government  enacted the
     Interim  Payment  System  ("IPS") for  reimbursement  of home care services
     provided under Medicare.  Prior to enactment of the IPS, home care services
     were  reimbursed  based on cost subject to a cap  determined  by the Health
     Care Financing Administration.  The IPS reimburses home care services based
     on costs,  subject to both a  per-beneficiary  limit and a per-visit limit.
     Further, the IPS reduced the per-visit limit to 1994 levels. As a result of
     these cuts in reimbursement,  provider margins have been reduced.  In order
     to operate at the lowered  reimbursement  rates, home health care companies
     reduced  the  services  provided to patients  by  providing  fewer  patient
     visits. In addition, the regulatory climate that ensued in home health care
     caused a lower level of physician referrals.

     In 1998, the Company recorded  non-recurring  charges and other adjustments
     of $66  million  related  to the  restructuring  of  the  Company's  Health
     Services  division.  These  charges,  which  were  primarily  for 60 office
     closings  and  consolidations  in the  United  States,  were  taken to help
     position  the  Company to operate  more  efficiently  under the new IPS. In
     addition, the Company has also made significant  technological  investments
     in order to improve operational efficiencies and employee retention levels.
     The benefit of the restructuring began to be realized in the second quarter
     of 1998.

         Included in this  provision  was $37  million  charged to selling,
         general and administrative expenses, which included lease payments
         of $3 million, employee severance of $4 million, professional fees


                                       6
<PAGE>
         and  related  costs  of $13  million,  fixed  asset  and  software
         write-offs  of $5 million to reflect  the loss  incurred  upon the
         Company's  decision  to dispose  of the  assets in certain  closed
         offices, and an increase in the allowance for doubtful accounts of
         $12 million.  The charge for  professional  fees and related costs
         resulted  from the  settlement  with several  government  agencies
         regarding certain past business practices of Quantum, the level of
         effort required to respond to the significant  inquiries conducted
         by the  government,  and costs incurred to redesign the credit and
         collection  process of the home health business.  All closures and
         consolidations, related to this charge, of facilities and employee
         terminations  have been  completed.  The  allowance  for  doubtful
         accounts was increased  because the  collection of  receivables is
         highly  dependent  on the  service  provider's  ability to provide
         certain evidence of service and  authorization  documentation to a
         variety of third-party payors. The office closings,  consolidation
         of  certain  business  service  centers  and  the  termination  of
         employees are all events that, in the Company's  past  experience,
         impair the ability to provide the aforementioned documentation and
         to collect on receivables.

         In addition,  the Company  recorded a reduction in revenues in the
         second  quarter of 1998 of $14  million in  anticipation  of lower
         Medicare  reimbursements  resulting  from  the new  per-visit  and
         per-beneficiary  limits that have been  imposed by Medicare  under
         the Interim Payment System.

         The  Company  recorded a charge to cost of sales of $15 million to
         reflect the estimated  increase in costs that have been  incurred,
         but  not  yet  reported,  based  upon a  change  in the  actuarial
         estimates  utilized to determine  the level of service to patients
         covered under the Company's capitated contracts.

     The major  components,  and amount of costs  charged  during the six months
     ended July 4, 1999, of the previous years' special charges,  as well as the
     1999 special charge, were as follows:

5.   Long-Term Debt
     --------------
     In February 1999, the Company's  revolving credit agreement,  which expires
     in 2001, was amended, to revise the provision related to the maintenance of
     various  financial  ratios and  covenants,  including  granting the Company
     approval to  repurchase up to $40 million of the  convertible  subordinated
     debentures.   The  Company   retired  $7.7   million  of  the   convertible
     subordinated debentures at 88.5 percent of the principal amount,  resulting
     in a gain of  approximately  $.9 million in January 1999. In May 1999,  the
     Company's  revolving credit agreement was further amended to revise various
     financial  ratios and covenants and to restrict  further  repurchase of the
     convertible  subordinated  debentures,  as  well  as the  Company's  common
     shares.

     Interest expense, net, consists primarily of interest on long-term debt for
     the  quarter  of $11  million  in 1999 and $8  million  in 1998,  offset by
     interest income from investments of $.6 million for 1999 and $1 million for
     1998. Interest expense for the six months was $21 million,  net of interest
     income of $1 million in 1999 and $15 million,  net of interest income of $2
     million in 1998.

7.   Subsequent Event
     ----------------
     On August 18, 1999, the Company  announced it intends to merge its staffing
     and information technology services businesses with Adecco S.A. On closing,
     the  Company's  health  services  business  will  be  split  off to  Olsten
     shareholders as an independent, health services company.

     When the transactions  become  effective,  each holder of Olsten stock will
     receive  for each share of Olsten  common  stock and Olsten  Class B stock,
     $8.75 in cash, or 0.12472 of an Adecco  American  Depositary  Receipt (ADR)
     (one ADR represents  one-eighth  of one share of Adecco common stock), or a
     mixture of cash and Adecco ADRs valued in the  aggregate  at  approximately
     $8.75 per Olsten  share,  subject to proration in order that the  aggregate
     consideration received by all holders will be half cash and half Adecco ADR
     shares.  The value of the stock  received  by  shareholders  in the  health
     services company will be determined upon commencement of trading in the new
     security.

     The transactions  required by the merger agreement  require the affirmative
     vote of holders of a majority of Olsten's  common  stock and Class B stock,
     voting  as a  single  class,  as well as  customary  regulatory  and  other
     conditions.  Stuart  Olsten,  Chairman of the  Company,  and certain  other
     holders of the  Company's  Class B stock,  constituting  a majority  of the
     voting power of the Company's  combined classes of stock, have committed to
     vote in favor of the transactions.

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

Results of Operations
- ---------------------
Revenues increased 11 percent, or $123 million, during the second quarter and 12
percent,  or $271 million,  for the first six months of 1999, with 7 percent and
11  percent  attributable  to  acquisitions,  respectively.  Staffing  Services'
revenues increased 9 percent, or $65 million, for the second quarter of 1999 and
12 percent,  or $162 million,  for the six months of 1999.  In Europe,  Staffing
Services'  second  quarter of 1999  revenue grew by 36 percent,  principally  in
France  and  Scandinavia,  reflecting  industry  growth and  favorable  economic
conditions,  while North  American  second  quarter of 1999 revenues  declined 3










                                       10
<PAGE>
percent  due, in part,  to the  historically  low level of  unemployment  in the
United States.  Partially  offsetting this decrease was a 37 percent increase in
the Canadian staffing business' second quarter of 1999 revenues and a 31 percent
increase in the Company's  accounting and financial services specialty division.
Staffing  Services'  revenues were  unfavorably  impacted by changes in currency
exchange rates during the second quarter of 1999 due to the strengthening of the
U.S. dollar relative to currencies in Europe, particularly in France, Norway and
the United  Kingdom.  At  constant  exchange  rates,  the  increase  in Staffing
Services'  revenues would be 11 percent,  or $77 million.  For the six months of
1999,  Staffing Services' revenues would have been $1.5 billion,  an increase of
13 percent,  had  exchange  rates  remained  unchanged.  Information  Technology
Services'  revenues were  essentially  flat in both North America and Europe for
the  second  quarter  of 1999 and grew 8 percent,  or $16  million,  for the six
months of 1999. Health Services' revenues increased 18 percent,  or $57 million,
for the second  quarter,  and 14 percent,  or $93  million,  for the six months,
driven by growth in the  Infusion,  Network  and  Staffing  business,  while the
Nursing  business  was flat due,  in part,  to the impact of the 1998  change to
Medicare's Interim Payment System discussed below.

Gross profit margins, as a percentage of revenues, increased to 24.3 percent and
24.5  percent for the second  quarter and six months from 21.6  percent and 23.4
percent for last year's second quarter and six months,  respectively.  Excluding
the  impact of the  non-recurring  charge in the second  quarter of 1998,  gross
profit  margins  increased from 23.9 percent and remained  essentially  flat for
last year's  second  quarter and six months,  respectively.  Staffing  Services'
gross  profit  margins  declined  for the  quarter and six months as a result of
decreased markups, increased subcontractor utilization, and growth in low margin
Corporate  Accounts and  Partnership  business in North  America.  Additionally,
increased  international  competition,  a changing  business  mix and  increased
social costs in Europe reduced margins.  Information  Technology's  gross profit
margins  remained  essentially  flat in comparison to the second quarter and six
months of 1998.  Health  Services'  gross  profit  margins  increased  slightly,
excluding the effect of the  non-recurring  charge and other  adjustments in the
second  quarter of 1998,  from 32.3  percent to 34.2  percent in the quarter and
33.3 percent to 34.1 percent in the six months.

On  March  30,  1999,  the  Company  announced  plans to take a  special  charge
aggregating $102 million.  The charge provides for the settlement of two federal
investigations  focusing on the Company's  Medicare home office cost reports and
certain  transactions  with  Columbia/HCA and a provision of $46 million for the
realignment of business  units as part of a new  restructuring  plan,  including
compensation  and  severance  costs  of $22  million  to be paid to  operational
support staff, branch administrative personnel and management,  asset write-offs
of $16  million  and  integration  costs of $8  million,  primarily  related  to
obligations  under  lease  agreements  for offices  and other  facilities  being
closed.  With  respect to the two  government  investigations,  the final civil,
administrative  and criminal  agreements  were  finalized and signed on July 19,
1999 and the  settlement  amount was paid on August 11,  1999.  The  payment was
funded by the Company's  revolving credit agreement in the amount of $45 million
with the remainder  coming from operating cash flows.  Asset  write-offs  relate
primarily  to fixed  assets  being  disposed  of in  offices  being  closed  and
facilities being consolidated as well as fixed assets and goodwill  attributable
to the Company's exit from certain businesses previously acquired but not within
the Company's strategic objectives.  The Company expects that the realignment of
the business units will achieve a reduction of expenses of  approximately  $13.6
million for the last three quarters of 1999, due to reduced employees, lease and
depreciation expenses.


                                       11
<PAGE>
         The Health Services' division represented $73 million of the total
         charge,  inclusive of a provision  for the  settlement  of the two
         government   investigations  of  $56  million,   compensation  and
         severance costs of $5 million,  asset write-offs of $7 million and
         integration costs of $5 million.

         The charge for the Staffing Services' division totaled $16 million
         and related to  business  realignments,  including  $6 million for
         compensation  and severance costs, $8 million for asset write-offs
         and $2 million for integration costs.

         The  balance of the  charge of $13  million  relates to  corporate
         operations and consists  primarily of  compensation  and severance
         costs.

         As of the end of the  second  quarter  of 1999,  60 percent of the
         closures and  consolidations of facilities have been completed and
         approximately  70 percent of the  expected 640  terminations  have
         occurred.

In 1998,  as a part of the  Balanced  Budget  Act,  the  government  enacted the
Interim Payment System ("IPS") for  reimbursement of home care services provided
under  Medicare.  Prior  to  enactment  of the  IPS,  home  care  services  were
reimbursed  based  on  cost  subject  to a cap  determined  by the  Health  Care
Financing Administration.  The IPS reimburses home care services based on costs,
subject to both a per-beneficiary  limit and a per-visit limit. Further, the IPS
reduced  the  per-visit  limit  to 1994  levels.  As a result  of these  cuts in
reimbursement,  provider  margins have been reduced.  In order to operate at the
lowered  reimbursement  rates,  home health care companies  reduced the services
provided to  patients by  providing  fewer  patient  visits.  In  addition,  the
regulatory  climate  that  ensued in home  health  care  caused a lower level of
physician referrals.

         In 1998,  the  Company  recorded  non-recurring  charges and other
         adjustments  of $66 million  related to the  restructuring  of the
         Company's  Health  Services  division.  These charges,  which were
         primarily for 60 office closings and  consolidations in the United
         States,  were taken to help  position  the Company to operate more
         efficiently  under the new IPS. In addition,  the Company has also
         made  significant  technological  investments  in order to improve
         operational   efficiencies  and  employee  retention  levels.  The
         benefit of the  restructuring  began to be  realized in the second
         quarter of 1998.

         Included in this  provision  was $37  million  charged to selling,
         general and administrative expenses, which included lease payments
         of $3 million, employee severance of $4 million, professional fees
         and  related  costs  of $13  million,  fixed  asset  and  software
         write-offs  of $5 million to reflect  the loss  incurred  upon the
         Company's  decision  to dispose  of the  assets in certain  closed
         offices, and an increase in the allowance for doubtful accounts of
         $12 million.  The charge for  professional  fees and related costs
         resulted  from the  settlement  with several  government  agencies
         regarding certain past business practices of Quantum, the level of





                                       12
<PAGE>
         effort required to respond to the significant  inquiries conducted
         by the  government,  and costs incurred to redesign the credit and
         collection  process of the home health business.  All closures and
         consolidations, related to this charge, of facilities and employee
         terminations  have been  completed.  The  allowance  for  doubtful
         accounts was increased  because the  collection of  receivables is
         highly  dependent  on the  service  provider's  ability to provide
         certain evidence of service and  authorization  documentation to a
         variety of third-party payors. The office closings,  consolidation
         of  certain  business  service  centers  and  the  termination  of
         employees are all events that, in the Company's  past  experience,
         impair the ability to provide the aforementioned documentation and
         to collect receivables.

         In addition,  the Company  recorded a reduction in revenues in the
         second  quarter of 1998 of $14  million in  anticipation  of lower
         Medicare  reimbursements  resulting  from  the new  per-visit  and
         per-beneficiary  limits that have been  imposed by Medicare  under
         the Interim Payment System.

         The  Company  recorded a charge to cost of sales of $15 million to
         reflect the estimated  increase in costs that have been  incurred,
         but  not  yet  reported,  based  upon a  change  in the  actuarial
         estimates  utilized to determine  the level of service to patients
         covered under the Company's capitated contracts.

Selling,  general and  administrative  expenses decreased to $267 million in the
second  quarter of 1999 from $287  million in the second  quarter of 1998 due to
the  non-recurring  charges  and other  adjustments  and  recorded in the second
quarter of 1998.  Excluding the charge,  such expenses,  at 21.3% and 21.9% as a
percentage  of revenue  for the second  quarter of 1999 and 1998,  respectively,
have  remained  flat  for  the  quarter.   Conversely,   selling,   general  and
administrative  expenses  increased to $639 million from $524 million in the six
months  due to the  special  charge  recorded  in the  first  quarter  of  1999.
Excluding both charges, selling, general and administrative expenses for the six
months have been  essentially  flat as a percentage  of revenue at 22.2% in 1998
and 21.9% in 1999.

Net interest  expense was $10.8 million and $7.5 million for the second quarters
of 1999 and 1998,  respectively,  and $20  million  and $13  million for the six
months of 1999 and 1998. Net interest  primarily  reflected  borrowing  costs on
long-term debt offset by interest income on investments.  The increase  resulted
from  interest  expense  incurred  as the  Company  continued  to fund  both its
acquisition  program and working  capital  requirements,  particularly  accounts
receivable,  necessary to support growth in its Staffing  Services' business and
Infusion business.

Liquidity and Capital Resources
- -------------------------------
Working  capital  at July 4,  1999,  including  $15  million  in cash,  was $774
million,  an  increase  of 15 percent  versus  $675  million at January 3, 1999.
Receivables,  net, increased $141 million,  or 14 percent,  predominantly due to
revenue growth and  acquisitions in the Staffing  Services'  business as well as
growth in Health Services' Infusion business,  which requires additional working
capital.




                                       13
<PAGE>
The  Company  has a  revolving  credit  agreement  for  up to  $400  million  in
borrowings  and letters of credit.  In February  1999,  the Company's  revolving
credit  agreement,  which expires in 2001, was amended,  to revise the provision
related to the maintenance of various financial ratios and covenants,  including
granting the Company approval to repurchase up to $40 million of the convertible
subordinated  debentures.  The Company  retired $7.7 million of the  convertible
subordinated debentures at 88.5 percent of the principal amount,  resulting in a
gain of  approximately  $.9 million in January 1999. In May 1999,  the Company's
revolving credit  agreement was further amended to revise the provision  related
to the  maintenance  of various  financial  ratios and covenants and to restrict
further repurchase of the convertible  subordinated  debentures,  as well as the
Company's  common  shares.  As of July 4,  1999,  there  were  $344  million  in
borrowings and $15 million in standby  letters of credit  outstanding  under the
revolving credit agreement.  The Company has invested available funds in secure,
short-term, interest-bearing investments.

The  Company  anticipates  that,  in addition  to its  projected  cash flow from
operations,  new  borrowings  may be  required to meet the  Company's  projected
working capital requirements to fund capital expenditures  currently anticipated
by the  Company.  Although no  assurance  can be given,  the  Company  currently
believes that cash flows from  operations,  borrowings  available to the Company
under existing financing agreements,  and additional borrowings that the Company
believes  it will be able to obtain  should be  adequate  to meet its  projected
requirements  during  1999 and  thereafter.  If cash  flows from  operations  or
availability   under   existing  and  new   financing   agreements   fall  below
expectations,  the Company may be forced to delay planned capital  expenditures,
reduce operating  expenses,  or consider other alternatives  designed to enhance
the  Company's  liquidity.  On August 11, 1999,  the Company paid $61 million in
settlement  of the U.S.  Department  of Justice  home  office  cost  reports and
Columbia/HCA  investigation  of which $45  million  was funded by the  Company's
revolving credit agreement with the remainder coming from operating cash flows.

The Company's  1999 second  quarter  dividend on common stock and Class B common
stock was $.04 per share.

Year 2000
- ---------
The Year 2000 issue  concerns the inability of  information  systems to properly
recognize and process date-sensitive information beyond January 1, 2000.

The Company's technical infrastructure,  encompassing all business applications,
is planned to be Year 2000 ready.  Systems not directly related to the financial
operations  of the  business,  primarily  voice  communications,  are also being
upgraded to help ensure readiness.

The North American  Staffing  Services business is achieving Year 2000 readiness
by replacing all business applications and related infrastructure with compliant
technology.  This project, referred to as Project REach, is being implemented to
increase  efficiencies and improve the Company's  ability to provide services to
customers.  The selected  systems are Year 2000  compliant  and,  therefore,  no
remediation of current applications is necessary. Project REach is approximately
95 percent completed and is scheduled to be fully implemented by September 1999.
The Company's  European and Latin  American  staffing  operations  are achieving
readiness  primarily  through  remediation  of  existing  systems  and  both are
expected to be completed by October 31, 1999.

The Information  Technology  Services business  required minimal  remediation to
achieve Year 2000 compliance, and was completed June 30, 1999.

                                       14
<PAGE>
In the Health Services  segment,  systems  critical to the business,  which have
been  identified as non-year  2000  compliant,  are being  replaced as part of a
project, referred to as Project REO, which is also being implemented to increase
efficiencies and improve the Company's ability to provide services to customers.
The new  infrastructure,  which  is Year  2000  compliant,  is  currently  being
implemented  in field  offices and is scheduled  for  completion  by October 31,
1999. Other Health Services' systems, which require remediation, are expected to
be completed by October 31, 1999.

The total cost of the Company's remediation plan (exclusive of Project REach and
Project REO costs) is estimated to be approximately $3 million.

As part of its Year 2000  readiness  activities,  the Company has  contacted its
significant  vendors  and third  parties  to  determine  the extent to which the
Company is vulnerable to their potential  failure to remediate their own systems
to  address  the Year 2000  issues.  Approximately  93% of those  inquired  have
responded in writing and indicated their current compliance or that they will be
compliant by the end of 1999.

With respect to the risks associated with its systems, the Company believes that
the  most  reasonably  likely  worst  case  scenario  is that  the  Company  may
experience  minor system  malfunctions and errors in the early days and weeks of
the Year 2000.  The Company  does not expect  these  problems to have a material
impact on the Company's ability to place and pay workers or invoice customers.

The  Company is not  heavily  reliant  on  electronic  transmissions  from third
parties.  With  respect  to the risks  associated  with the third  parties,  the
Company  believes  that the most  reasonably  likely worst case scenario is that
some of the Company's  vendors and customers will not be compliant.  The Company
believes that the number of such third  parties will have been  minimized by the
Company's program of contacting significant vendors and large customers. Despite
the Company's diligence,  there can be no guarantee that significant vendors and
third  parties that the Company  relies upon to conduct day to day business will
be compliant.  Failure by these  companies,  or any  governmental  entities,  to
remediate  their  systems  on  a  timely  basis  could  impact  cash  flow  from
operations.

Due to the general  uncertainty  inherent in the Year 2000 issue  resulting,  in
part, from the  uncertainty of the Year 2000 readiness of third-party  suppliers
and customers,  and government  agencies,  the Company is unable to determine at
this time whether the  consequences  of Year 2000  failures will have a material
impact on the Company's results of operations, liquidity or financial condition.
The continuing  Year 2000 effort is expected to help reduce the Company's  level
of uncertainty about the Year 2000 issue and, in particular, about the Year 2000
readiness.  The Company believes that the implementation of new business systems
and the  completion  of its Year 2000 plan as  scheduled  should help reduce the
likelihood of significant interruptions of normal operations.

The Company's plan is to address its significant Year 2000 issues prior to being
affected by them.  Should the Company identify  significant risks related to its
Year 2000 readiness or its progress deviates from the anticipated timeline,  the
Company will develop contingency plans as deemed necessary at that time.

The  failure  to  correct  a  material  Year  2000  problem  could  result in an
interruption or a failure of certain normal  business  activities or operations.
Such failures  could  materially and adversely  affect the Company's  results of
operations, liquidity and financial condition.

Item 3.  Quantitative and Qualitative Disclosures about Market Risk

The  Company's  exposure to market risk for  changes in interest  rates  relates
primarily  to the fair value of  long-term  fixed-rate  debt.  The  Company  has
historically  managed  interest  rates through the use of a combination of fixed
and variable  rate  borrowings.  Generally,  the fair market value of fixed rate
debt will increase as interest rates fall and decrease as interest rates rise.

The Company's  long-term debt is primarily  composed of fixed rate  obligations.
Based  on the  overall  interest  rate  exposure  on the  Company's  fixed  rate
borrowings at July 4, 1999, 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.

Based on variable rate debt levels, a 10 percent change in market interest rates
(54 basis points on a weighted  average) would have less than a 3 percent impact
on the Company's interest expense, net.

Other than intercompany transactions between the United States and the Company's
foreign entities,  the Company generally does not have significant  transactions
that are denominated in a currency other than the functional currency applicable
to each entity.

Fluctuations in currency exchange rates may also impact the shareholders' equity
of  the  Company.   The  assets  and  liabilities  of  the  Company's   non-U.S.
subsidiaries are translated into U.S. dollars at the exchange rates in effect at
the balance sheet date.  Revenues and expenses are translated into U.S.  dollars
at the weighted average exchange rate for the quarter. The resulting translation
adjustments  are  recorded  in   shareholders'   equity  as  accumulated   other
comprehensive income (loss).

Although  currency   fluctuations  impact  the  Company's  reported  results  of
operations, such fluctuations generally do not affect the Company's cash flow or
result in actual  economic gains or losses.  Each of the Company's  subsidiaries
derives  revenues and incurs expenses  primarily  within a single  country,  and
consequently,  does not generally  incur currency  risks in connection  with the
conduct of normal  business  operations.  The  Company  generally  has few cross
border transfers of funds,  except for transfers from or to the United States as
working  capital  loans.  To reduce the currency risk related to the loans,  the
Company may borrow funds under the existing  Revolving  Credit  Agreement in the
foreign currency to lend to the subsidiary.

Foreign exchange gains and losses are included in the Consolidated Statements of
Operations and historically  have not been  significant.  The Company  generally
does not engage in hedging  activities,  except as discussed  above. The Company
did not hold any derivative instruments at July 4, 1999.

                        PART II - OTHER INFORMATION

Item 1.     Legal Proceedings.
            ------------------
            On September 8, 1998, a Consolidated  Amended Class Action Complaint
            (the "Amended  Complaint")  was filed by the  plaintiffs in the four
            previously  disclosed  purported  class action  lawsuits  (Weichman,
            Goldman,  Waldman and Cannold) pending against Olsten and certain of
            its officers and directors  (collectively,  the "Class Action"). The
            Amended  Complaint  asserts claims under  Sections 10(b)  (including
            Rule  10b-5  promulgated   thereunder),   14(a)  and  20(a)  of  the
            Securities  Exchange Act of 1934 and Sections 11, 12(a)(2) and 15 of
            the Securities Act of 1933. On October 19, 1998, the Company and the
            individual  defendants  served a motion seeking an Order  dismissing
            the Amended Complaint; that motion was fully briefed on December 23,
            1998.  The Amended  Complaint  seeks  certification  of the proposed
            class,  a judgment  declaring the conduct of the defendants to be in
            violation  of  the  law,   unspecified   compensatory   damages  and
            unspecified  costs  and  expenses,  including  attorneys'  fees  and
            experts'  fees.  While the  Company is unable at this time to assess
            the probable  outcome of the Class Action or the  materiality of the
            risk of loss in connection therewith (given the preliminary stage of
            the Class  Action and the fact that the Amended  Complaint  does not
            allege damages with any  specificity),  the Company believes that it
            acted   responsibly   with  respect  to  its  shareholders  and  has
            vigorously defended the Class Action.

            On or about May 11,  1999,  a Complaint  was served in a  derivative
            lawsuit,  captioned Robert Rubin, et al. v. John M. May, et al., No.
            17135-NC  (Delaware  Chancery  Court),  which was filed  against the
            following current and former directors of the Company:  John M. May,
            Raymond S.  Troubh,  Jo[sh] S.  Weston,  Victor F. Ganzi,  Stuart R.
            Levine, Frank N. Liguori,  Miriam Olsten,  Stuart Olsten and Richard
            J.  Sharoff.  The  Complaint,   which  names  Olsten  as  a  nominal
            defendant,  alleges a claim for breach of fiduciary  duties  arising
            out  of  the  Class  Action  referenced  above  and  the  Healthcare
            Investigations  defined and referenced in Item 5, below.  Plaintiffs
            seek a  judgment  (1)  requiring  the  defendants  to account to the
            Company  for  unspecified   alleged   damages   resulting  from  the
            defendants'  alleged  conduct;   (2)  directing  the  defendants  to
            establish  and  maintain  effective  compliance  programs;  and  (3)
            awarding plaintiffs the costs and expenses of the lawsuit, including
            reasonable attorneys' fees.

Item 5.     Other Information.
            ------------------
            Government  Investigations.  The Company's home health care business
            is subject to extensive  federal and state regulations which govern,
            among  other   things,   Medicare,   Medicaid,   CHAMPUS  and  other
            government-funded  reimbursement  programs,  reporting requirements,
            certification  and  licensure  standards  for  certain  home  health
            agencies    and,    in   some   cases,    certificate-of-need    and
            pharmacy-licensing  requirements.  The Company is also  subject to a
            variety of federal and state  regulations  which  prohibit fraud and
            abuse in the delivery of health care  services,  including,  but not
            limited to, prohibitions against the offering or making of direct or
            indirect  payments  for the  referral  of  patients.  As part of the
            extensive  federal and state regulation of the Company's home health
            care   business,   the  Company  is  subject  to  periodic   audits,
            examinations and investigations  conducted by or at the direction of
            governmental investigatory and oversight agencies.  Violation of the
            applicable federal and state health care regulations can result in a
            health  care  provider  being  excluded  from  participation  in the
            Medicare,  Medicaid  and/or  CHAMPUS  programs,  and can subject the
            provider to civil and/or criminal penalties.

            The Company has cooperated with the previously disclosed health care
            industry  investigations  being  conducted  by certain  governmental
            agencies (collectively, the "Healthcare Investigations").

            Among the Healthcare Investigations with which the Company continues
            to cooperate is that being conducted into the Company's  preparation
            of Medicare cost reports by the Office of Investigations  section of
            the  Office  of  Inspector   General  (an  agency  within  the  U.S.
            Department of Health and Human Services) and the U.S.  Department of
            Justice (the "Cost Reports Investigation").

            The Company also continues to cooperate with the U.S.  Department of
            Justice and other federal  agencies  investigating  the relationship
            between Columbia/HCA Healthcare Corporation and Olsten in connection
            with the  purchase,  sale  and  operation  of  certain  home  health
            agencies  which had been owned by  Columbia/HCA  and  managed  under
            contract  by  Olsten  Health  Management,  a unit of  Olsten  Health
            Services that provides  management  services to hospital-based  home
            health agencies (the "Columbia/HCA Investigation").

            The Company  continues to cooperate  with various  state and federal
            agencies, including the U.S. Department of Justice and the Office of
            the  Attorney  General  of New  Mexico,  in  connection  with  their
            investigations  into certain healthcare  practices of Quantum Health
            Resources  ("Quantum").  Among the matters into which the government
            has been  inquiring are  allegations  of improper  billing and fraud
            against various  federally-funded medical assistance programs on the
            part of Quantum and its  post-acquisition  successor,  the  Infusion
            Therapy  Services  division of Olsten Health  Services (the "Quantum
            New Mexico Investigation"). Most of the time period that the Company
            understands  to be at issue in the Quantum New Mexico  Investigation
            predates the Company's June 1996 acquisition of Quantum.

            On July 19,  1999,  the  Company  entered  into  written  civil  and
            criminal  agreements with the U.S. Department of Justice (and, as to
            the civil  agreement,  the Office of  Inspector  General of the U.S.
            Department   of  Health   and   Human   Services)   finalizing   the
            understanding  that it  announced  on March 30,  1999 to settle  the
            civil and criminal aspects of the Cost Reports Investigation and the
            Columbia /HCA  investigation.  Pursuant to the  settlement,  (a) the
            Company  paid on August 11,  1999 the sum of $61 million to the U.S.
            Department  of Justice,  including  approximately  $10.1  million in
            criminal   fines  and   penalties;   (b)  in  connection   with  the
            Columbia/HCA  Investigation,  a subsidiary of the Company,  Kimberly
            Home Health Care, Inc., a Missouri  corporation,  pled guilty in the
            United States District Courts for the Northern  District of Georgia,
            the Southern District of Florida and the Middle District of Florida,
            respectively,  to a criminal  violation  of the federal  mail fraud,
            conspiracy  and kickback  statutes;  (c) Kimberly  Home Health Care,
            Inc. has been permanently  excluded from  participation in Medicare,
            Medicaid and all other federal health care programs as defined in 42
            U.S.C. ss.1320a-7b(f);  and (d) the Company has executed a Corporate
            Integrity Agreement with the Office of Inspector General of the U.S.
            Department of Health and Human Services.

            By letter dated June 30, 1999,  the Medicare  Fraud  Control Unit of
            the New Mexico Attorney  General's  Office notified the Company that
            it has declined to criminally prosecute the so-called "J-Code issue"
            relating to Quantum's  past practices in seeking  government  health
            care reimbursement.

            On January 28, 1999, the Company  announced that it had been advised
            by the  United  States  Attorney's  Office for the  District  of New
            Mexico ("New Mexico U.S.  Attorney's  Office")  that,  in connection
            with the  Quantum  New  Mexico  Investigation,  it had  dropped  its
            criminal  investigation into certain past practices of Quantum.  The
            criminal aspect of the Quantum New Mexico  Investigation had focused
            on  allegations  of  improper  billing  and  fraud  against  various
            federally funded medical assistance  programs on the part of Quantum
            during the period  between  January  1992 and April 1997.  By letter
            dated  February  1, 1999,  the New  Mexico  U.S.  Attorney's  Office
            advised the Company  that,  having ended its criminal  inquiry,  the
            Office has  referred  the Quantum  matter to its  Affirmative  Civil
            Enforcement  ("ACE")  Section.  As it had  done  with  the  Criminal
            Division  of the New Mexico  U.S.  Attorney's  Office,  the  Company
            intends  to  cooperate  fully  with that  Office's  ACE  Section  in
            connection  with its civil inquiry into the Quantum  matter that has
            been referred to it.  Although,  at this time, the Company is unable
            to  predict  what  relief,  if any,  the ACE  Section  will  seek in
            connection  with the civil  Quantum New Mexico  Investigation,  such
            relief could include money damages and/or civil penalties.

Act (the  "Certificate  of  Merger").  The date and time when the  Merger  shall
become effective is herein referred to as the "Effective Time."

in effect  immediately  prior to the Effective Time, shall be the By-Laws of the
Surviving Corporation until thereafter amended as provided by law.

          Section 1.04  Directors  and Officers of  Surviving  Corporation.  The
initial directors of the Surviving  Corporation shall be those persons who serve

as officers of Olsten  immediately  prior to the  Effective  Time,  in each case
until their  successors  are elected and qualified or until their earlier death,

          Section 1.05 Stockholders'  Meetings. (a) Olsten shall take all action
necessary in accordance with applicable law and its Certificate of Incorporation
and  By-Laws  to call and  convene a special  meeting of its  stockholders  (the
"Olsten  Special  Meeting"  and,  together with the Adecco  Special  Meeting (as
defined below), the "Special Meetings") as soon as practicable to consider, vote
upon and  obtain  the  approval  of this  Agreement,  the  Merger  and the other
transactions  contemplated  hereby by a majority of the voting power represented
by the  outstanding  shares of Olsten Stock and Olsten Class B Stock entitled to
vote thereon, voting together as a single class. Olsten shall, through its Board
of Directors,  (i) recommend to its stockholders approval of this Agreement, the

and  shall  not  withdraw,  modify  or  change  in any  manner  or  take  action
inconsistent with its recommendation of this Agreement,  the Merger or the other
transactions  contemplated  hereby  and  shall  not  resolve  to do  any  of the
foregoing  and publicly  disclose  such  resolution;  provided,  however,  that,
subject to compliance  with the provisions of Section 5.02 hereof,  the Board of
Directors of Olsten may fail to make its  recommendation  to its stockholders or
may withdraw,  modify or change in any manner or take action  inconsistent  with
such  recommendation or resolve to do any of the foregoing and publicly disclose
such  resolution  if such  Board of  Directors  reasonably  believes  after  (x)
receiving a Superior  Proposal (as hereinafter  defined) which was not solicited
by it after July 26, 1999 and which did not result from a breach of Section 5.02
hereof,  (y)  receiving the advice of outside legal counsel that failure to take
such action would be a breach of its fiduciary duties to its stockholders  under
applicable law and (z) receiving the advice of a financial advisor of nationally
recognized reputation that the party making such proposal is financially capable
and that such Superior Proposal is more favorable from a financial point of view
to its stockholders  than the Merger and the Split-Off,  that the making of such
recommendation or the failure to so withdraw,  modify or change in any manner or
take any action inconsistent with such recommendation or to resolve to do any of
the foregoing and publicly  disclose  such  resolution  would be a breach of its
fiduciary  duties under  applicable  law and (ii) cause to be solicited from its
stockholders  proxies  regarding  approval and adoption of this  Agreement,  the
Merger and the other transactions contemplated hereby.

                              CONVERSION OF SHARES

          Section 2.01 Olsten Common  Stock.  (a) At the  Effective  Time,  each
share of Olsten  Common Stock issued and  outstanding  immediately  prior to the
Effective Time (except for Dissenting Shares (as hereinafter  defined),  shares,
if any, owned by Olsten as treasury stock or owned by Adecco,  Merger Sub or any
of their wholly-owned  Subsidiaries or by any wholly-owned Subsidiary of Olsten)
shall,  by virtue of the  Split-Off and the Merger and without any action on the
part of the holder  thereof,  be converted  into the right to receive (x) all of
the  shares  of  validly  issued,  fully  paid  and  nonassessable  shares  (the
"Split-Off  Consideration")  of common  stock of OHS (the "OHS  Common  Stock"),
except for a nominal number of the outstanding  shares of OHS Common Stock which
may be  retained  by Olsten,  which  shares  shall be  identified,  prior to the
Effective  Time, in a writing between Olsten and Adecco and (y) either (A) $8.75
per share,  without  interest  (the "Cash  Consideration")  or (B) .12472 Adecco
American  Depositary  Shares  ("Adecco  ADSs"),  each  Adecco  ADS  representing
one-eighth of one validly issued, fully paid and nonassessable share of Adecco's
common  shares,  par value CHF 10.00 per  share  (the  "Adecco  Common  Stock"),
evidenced by American  Depositary Receipts of Adecco ("Adecco ADRs") (the "Stock
Consideration")  or (C) a  combination  of a fraction of an Adecco ADS and cash,
determined in accordance  with Section  2.01(d),  (e) or (f), as applicable (the
foregoing clause (A) or (B) or (C) (the "Merger Consideration"). The ADSs are to
be issued  pursuant  to a Deposit  Agreement  (the  "Deposit  Agreement")  dated





                                       4
<PAGE>
November  1994,  among  Adecco,  Morgan  Guaranty  Trust Company of New York, as
Depositary  and the holders from time to time of Adecco ADRs  evidencing  Adecco
ADSs  representing   Adecco  Common  Stock  issued  thereunder.   The  Split-Off
Consideration and the Merger Consideration  pursuant to this Section 2.01(a) are
hereinafter sometimes called the "Closing Consideration."

          (b)  Effect  on  Olsten  Common  Stock.  At  the  Effective  Time  all
outstanding  shares of Olsten Common Stock,  by virtue of the Merger and without
any action on the part of the holders  thereof,  shall no longer be  outstanding
and shall be canceled and retired and shall cease to exist, and each holder of a
certificate representing any such shares of Olsten Common Stock shall thereafter
cease to have any rights  with  respect to such shares of Olsten  Common  Stock,
except the right to receive the Closing  Consideration for such shares of Olsten
Common Stock as specified in the foregoing clause (a) upon the surrender of such
certificate in accordance  with Section 2.04 or dissenters'  rights  pursuant to
Section 2.07.

          (c) Election of Merger  Consideration.  Subject to the  allocation and
election procedures set forth in this Section 2.01 and Section 2.02, each holder
of record (as of the  Effective  Time) of shares of Olsten  Common Stock will be
entitled,  with  respect  to each  such  share,  to (i)  receive  the  Split-Off
Consideration and (ii)(A) elect to receive cash (a "Cash  Election"),  (B) elect
to receive  Adecco ADSs (a "Stock  Election"),  or (C) indicate that such record
holder  has  no  preference  as to  the  receipt  of  cash  or  Adecco  ADSs  (a
"Non-Election").  Any holder who fails to make a valid and timely election shall
be deemed to have made a  Non-Election.  All such  elections  shall be made on a
form designed for that purpose (a "Form of  Election")  in  accordance  with the
procedures specified in Section 2.02.

          (d) Excess Cash Elections. If the aggregate number of shares of Olsten
Common Stock covered by Cash Elections (the "Cash Election  Shares") exceeds the
Cash Election Number (as defined below),  then all shares of Olsten Common Stock
covered by Stock  Elections  and all shares of Olsten  Common  Stock  covered by
Non-Elections (the  "Non-Election  Shares") shall be converted into the right to
receive the Split-Off  Consideration and Stock Consideration,  and all shares of
Olsten Common Stock covered by Cash Elections  shall be converted into the right
to receive (in addition to the Split-Off  Consideration) Adecco ADSs and cash in
the following manner:

     each share shall be converted  into the right to receive (i) an amount
     in  cash,  without  interest,  equal  to the  product  of (x) the Cash
     Consideration and (y) a fraction (the "Cash Fraction"),  the numerator
     of which  shall be the Cash  Election  Number and the  denominator  of
     which shall be the total number of Cash  Election  Shares,  and (ii) a
     number of shares of Adecco  ADSs equal to the product of (x) the Stock
     Consideration and (y) a fraction equal to one minus the Cash Fraction.

          The "Cash Election  Number" shall be equal to (i) 50% of the number of
shares  of  Olsten  Common  Stock  outstanding  as of  immediately  prior to the
Effective  Time,  minus  (ii) (A) the  number of shares of Olsten  Common  Stock
represented by Dissenting Shares (as defined below), (B) the number of shares of
Olsten Common Stock for which cash in lieu of  fractional  shares of Adecco ADSs
is  payable  pursuant  to  Section  2.06 and (C) the  number of shares of Olsten
Common  Stock,  if any,  owned by Olsten as  treasury  stock or owned by Adecco,
Merger  Sub or any of their  wholly-owned  Subsidiaries  or by any  wholly-owned
Subsidiary of Olsten.

          (e)  Excess  Stock  Elections.  If the  aggregate  number of shares of
Olsten Common Stock covered by Stock  Elections  (the "Stock  Election  Shares")
exceeds the Stock Election Number (as defined below),  then all shares of Olsten
Common Stock  covered by Cash  Elections  and all shares of Olsten  Common Stock
covered  by  Non-Elections  shall be  converted  into the right to  receive  the
Split-Off  Consideration  and the Cash  Consideration,  and all shares of Olsten
Common Stock  covered by Stock  Elections  shall be converted  into the right to
receive (in addition to the Split-Off Consideration) Adecco ADSs and cash in the
following manner:

     each share shall be  converted  into the right to receive (i) a number
     of shares of Adecco ADSs equal to a fraction  (the "Stock  Fraction"),
     the  numerator  of which  shall be the Stock  Election  Number and the
     denominator  of which  shall be the  total  number  of Stock  Election
     Shares,  and (ii) an amount in cash,  without  interest,  equal to the
     product of (x) the Cash  Consideration and (y) a fraction equal to one
     minus the Stock Fraction.

          The "Stock Election Number" shall be equal to (i) 50% of the number of
shares  of  Olsten  Common  Stock  outstanding  as of  immediately  prior to the
Effective  Time minus (ii) the number of shares of Olsten Common Stock,  if any,
owned by Olsten as treasury stock or owned by Adecco, Merger Sub or any of their
wholly-owned Subsidiaries or by any wholly-owned Subsidiary of Olsten.

          (f) Insufficient  Elections. In the event that neither Section 2.01(d)
nor Section  2.01(e)  above is  applicable,  all shares of Olsten  Common  Stock
covered by Cash  Elections  shall be  converted  into the right to  receive  the
Split-Off Consideration and the Cash Consideration,  all shares of Olsten Common
Stock covered by Stock  Elections  shall be converted  into the right to receive
the  Split-Off  Consideration  and the Stock  Consideration,  and the  shares of
Olsten Common Stock covered by  Non-Elections,  if any,  shall be converted into
the right to receive (in addition to the  Split-Off  Consideration)  Adecco ADSs
and cash in the following manner:

     each share shall be converted  into the right to receive (i) an amount
     in  cash,  without  interest,  equal  to the  product  of (x) the Cash
     Consideration and (y) a fraction (the  "Non-Election  Fraction"),  the
     numerator of which shall be the excess,  if any, of the Cash  Election
     Number  over  the  total  number  of  Cash  Election  Shares  and  the
     denominator  of which  shall  be the  Non-Election  Shares  and (ii) a
     number of shares of Adecco  ADSs equal to the product of (x) the Stock
     Consideration  and (y) a fraction equal to one minus the  Non-Election
     Fraction.

          Section  2.02  Election  Procedures.  (a)  Elections  shall be made by
holders of Olsten Common Stock by mailing to the Exchange Agent (as  hereinafter
defined)  a Form  of  Election.  To be  effective,  a Form of  Election  must be
properly  completed,  signed and submitted to the Exchange Agent and accompanied
by  Certificates  (as  hereinafter  defined)  representing  the shares of Olsten
Common Stock as to which the election is being made. Holders of record of shares
of Olsten  Common Stock who hold such shares as  nominees,  trustees or in other
representative  capacities (a  "Representative")  may submit  multiple  Forms of
Elections, provided that such Representative certifies in writing that each such
Form of  Election  covers  all the  shares of Olsten  Common  Stock held by each





                                       6
<PAGE>
Representative  for  a  particular  beneficial  owner.  Olsten  shall  have  the
discretion,  which it may delegate in whole or in part to the Exchange Agent, to
determine  whether Forms of Election have been  properly  completed,  signed and
submitted or revoked and to disregard  immaterial  defects in Forms of Election.
The  decision  of  Olsten  (or the  Exchange  Agent)  in such  matters  shall be
conclusive and binding. Neither Olsten nor the Exchange Agent shall be under any
obligation to notify any person of any defect in a Form of Election submitted to
the Exchange Agent. The Exchange Agent shall make all computations  contemplated
by  Section  2.01 and this  Section  2.02  and all  such  computations  shall be
conclusive and binding on the holders of Olsten Common Stock.  Forms of Election
and other appropriate and customary  transmittal  materials (which shall specify
that delivery  shall be effected and risk of loss and title to the  Certificates
theretofore  representing  shares of Olsten  Common Stock shall pass,  only upon
proper  delivery of such  Certificates  to the  Exchange  Agent) in such form as
Adecco  and Olsten  shall  mutually  agree  shall be mailed on the date that the
Olsten Proxy Statement is first mailed to the stockholders of Olsten.

          (b) A holder of  Olsten  Common  Stock  who does not  submit a Form of
Election which is received by the Exchange Agent prior to the Election  Deadline
(as defined below) shall be deemed to have made a Non-Election. If Olsten or the
Exchange  Agent  shall  determine  that any  purported  Cash  Election  or Stock
Election  was not  properly  made with  respect  to any or all of the  shares of
Olsten Common Stock of a holder,  such purported Cash Election or Stock Election
shall be deemed to be of no force and effect  and the  stockholder  making  such
purported Cash Election or Stock Election shall, for purposes hereof,  be deemed
to have made a Non-Election.

          (c) Olsten shall use its  reasonable  best efforts to mail the Form of
Election to all persons or entities  who become  holders of Olsten  Common Stock
during the period  between  the record date for the Olsten  Special  Meeting and
10:00  a.m.,  New  York  time,  on the  date  five  business  days  prior to the
anticipated  Effective  Time and to make the Form of Election  available  to all
persons or entities who become holders of Olsten Common Stock subsequent to such
day and no later than the close of  business  on the  business  day prior to the
Effective  Time. A Form of Election  must be received by the  Exchange  Agent by
4:00 p.m. on the last  business day prior to the Effective  Time (the  "Election
Deadline")  in order to be  effective.  All  elections may be revoked in writing
until the Election Deadline.

          Section  2.03 Merger Sub Common  Stock;  Adecco  Owned  Olsten  Common
Stock.  (a) At the Effective Time,  each share of common stock,  par value $.001
per share,  of Merger Sub ("Merger  Sub Common  Stock")  issued and  outstanding
immediately  prior to the  Effective  Time  shall,  by virtue of the  Merger and
without  any action on the part of the holder  thereof,  be  converted  into one
validly issued,  fully paid and  nonassessable  share of common stock, par value
$.10 per share,  of the Surviving  Corporation  ("Surviving  Corporation  Common
Stock").

          (b) At the  Effective  Time all  outstanding  shares of Olsten  Common
Stock that are owned by Olsten as treasury stock and any shares of Olsten Common
Stock  that are owned by Adecco or  Merger  Sub or any  wholly-owned  Subsidiary
thereof or by any wholly-owned Subsidiary of Olsten, by virtue of the Merger and
without  any  action  on the part of the  holders  thereof,  shall no  longer be
outstanding and shall be canceled and retired and shall cease to exist, and each
holder of a  certificate  representing  any such shares of Olsten  Common  Stock
shall  thereafter cease to have any rights with respect to such shares of Olsten
Common Stock and no consideration shall be delivered in exchange therefor.

          Section 2.04  Exchange of Shares.  (a) Adecco and Olsten shall jointly
designate one or more persons in the United States to act as the Exchange  Agent
(the  "Exchange  Agent") for the purposes  described in Section 2.02 and for the
purpose of exchanging  certificates  representing  shares of Olsten Common Stock
for the Closing Consideration.  At least one business day prior to the Effective
Time,  Adecco  will  deposit  with  the  Exchange  Agent  the  aggregate  Merger
Consideration,  and  Olsten  shall  deposit  or cause  OHS to  deposit  with the
Exchange Agent the aggregate Split-Off Consideration, each to be paid in respect
of the shares of Olsten Common Stock.  For purposes of determining the aggregate
Merger  Consideration  and  the  aggregate  Split-Off  Consideration  to  be  so
deposited with the Exchange Agent, Adecco and Olsten shall assume that no holder
of shares of Olsten  Common  Stock will  perfect  his/her  right to appraisal of
his/her  shares of Olsten Common Stock  pursuant to Section 2.07 hereof.  Adecco
will pay all fees and expenses  associated  with the issuance of the Adecco ADSs
evidenced  by Adecco  ADRs to Morgan  Guaranty  Trust  Company  of New York,  as
depositary (the  "Depositary")  and the issuance by the Depositary of the Adecco
ADSs.

          (b)  Promptly  after the  Effective  Time,  Adecco  and the  Surviving
Corporation  shall cause the Exchange Agent to mail to each record holder, as of
the  Effective  Time,  of  an  outstanding   certificate  or  certificates  that
immediately  prior to the  Effective  Time  represented  shares of Olsten Common
Stock (the  "Certificates")  a form letter of  transmittal  (which shall specify
that delivery shall be effected,  and risk of loss and title to the Certificates
shall pass, only upon proper delivery of the Certificates to the Exchange Agent)
and  instructions  for use in effecting  the  surrender of the  Certificates  in
exchange for the Closing Consideration.

          (c) Upon surrender to the Exchange  Agent of a  Certificate,  together
with such letter of transmittal  duly executed,  the holder of such  Certificate
shall be entitled to receive in exchange therefor the Closing Consideration that
such holder has the right to receive under this Article II, and such Certificate
shall forthwith be canceled.  If any shares of Adecco ADSs are to be issued to a
person  other  than the  person in whose  name the  surrendered  Certificate  is
registered,   it  shall  be  a  condition  of  exchange  that  such  surrendered
Certificate  shall be properly endorsed or otherwise in proper form for transfer
and that the person  requesting  such  exchange  shall pay any transfer or other
taxes  required by reason of the exchange by a person other than the  registered
holder of the  Certificate  surrendered  or such person  shall  establish to the
satisfaction of Adecco that such tax has been paid or is not  applicable.  Until
surrendered  in  accordance  with the  provisions  of this  Section  2.04,  each
Certificate shall represent,  for all purposes, the right to receive the Closing
Consideration  in  respect  of the  number  of shares  of  Olsten  Common  Stock
evidenced by such  Certificate.  No dividends  or other  distributions  that are
declared after the Effective Time on Adecco Common Stock or OHS Common Stock and
payable to the  respective  holders of record  thereof after the Effective  Time
will be paid to  holders of  Certificates  until such  holders  surrender  their
Certificates.  Upon such  surrender,  Adecco or OHS,  as the case may be,  shall
deposit with the Exchange Agent and shall cause the Exchange Agent to pay to the
record holder of the shares of Adecco ADRs or Adecco  Common Stock,  as the case
may be,  representing Stock  Consideration or the recordholder of the OHS Common
Stock   representing   Split-Off   Consideration,   the   dividends   or   other
distributions,  excluding interest, that became payable after the Effective Time
and  were  not paid  because  of the  delay  in  surrendering  Certificates  for
exchange.




                                       8
<PAGE>
          (d) From and after the Effective Time,  there shall be no transfers on
the stock  transfer  books of Olsten of the shares of Olsten  Common  Stock that
were  outstanding  immediately  prior  to the  Effective  Time.  If,  after  the
Effective  Time,   Certificates   are  presented  to  Adecco  or  the  Surviving
Corporation,  they shall be canceled  and  exchanged as provided in this Article
II.

          (e) Neither  Olsten,  Adecco nor the  Surviving  Corporation  shall be
liable to any holder of Certificates  with respect to any Closing  Consideration
delivered to a public official  pursuant to any applicable  abandoned  property,
escheat or similar law.

          (f) Any  Closing  Consideration  payable to  holders of Olsten  Common
Stock  pursuant to Section 2.01 which  remains  undistributed  to the holders of
Olsten  Common  Stock for a period of six months after the Closing Date shall be
delivered to the  Surviving  Corporation,  upon its request,  and any holders of
Olsten Common Stock who have not surrendered  Certificates to the Exchange Agent
for the Closing Consideration or complied with the instructions in the letter of
transmittal,  as the case may be, shall  thereafter  look only to the  Surviving
Corporation for payment of the Closing Consideration.

          (g)  Notwithstanding  Section 2.01(a),  Adecco will provide holders of
Olsten  Common  Stock with the  option to elect to  receive  one share of Adecco
Common Stock for every eight  shares of Adecco ADSs such holder would  otherwise
be entitled to receive  pursuant to Section  2.01(a).  The Form of Election will
provide,  consistent with the terms of the Deposit Agreement,  for such election
option and  holders of Olsten  Common  Stock who wish to do so must  irrevocably
elect to receive  such  Adecco  Common  Stock at the time they  surrender  their
Certificates  representing  shares of Olsten Common Stock in accordance with the
provisions described in this Section 2.04, and the receipt of such Adecco Common
Stock will be deemed for all  purposes of this  Agreement  as the receipt of the
Stock Consideration and reference to Adecco ADSs in the provisions of Article II
shall,  as applicable  for such  purposes,  be deemed  references to such Adecco
Common Stock.

          Section  2.05 Effect on Options and  Convertible  Securities.  (a) The
parties hereto agree that each option to purchase  shares of Olsten Common Stock
(each a "Olsten  Option")  issued and  outstanding  under the Olsten  1994 Stock
Incentive  Plan,  the 1990  Nonqualified  Stock  Option  Plan  for  Non-Employee
Directors and Consultants, the Of Counsel Enterprises,  Inc. 1993 Employee Stock
Option Plan,  the IMI  Systems,  Inc.  1988  Incentive  Stock  Option Plan,  the
Lifetime  Corporation  1989  Non-Employee  Directors  Stock Option Plan, and the
Quantum  Health  Resources,  Inc. 1991  Restated  Stock Option Plan (the "Olsten
Plans"),  to the extent,  if any,  provided in the Olsten  Plans as in effect on
August  1,  1999,  shall  be fully  vested  and  exercisable  prior to or at the
Effective  Time.(b)  Effective as of the Effective Time, all outstanding  Olsten
Options held by Olsten Employees (as defined in the Employee Benefits Allocation
Agreement)  and Olsten  non-employee  directors  shall be adjusted as  described
below to represent  options to purchase  Adecco Common  Stock.  Each such Olsten
Option shall be adjusted such that (i) the aggregate post-transaction difference
between the fair market value of the Adecco  Common Stock  subject to the option
over  the  aggregate  exercise  price  of the  option  remains  the  same as the
aggregate pre-transaction difference between the fair market value of the Olsten
Common  Stock  subject to the option over the  aggregate  exercise  price of the





                                       9
<PAGE>
option,  (ii) the aggregate  exercise  price of the option  remains the same and
(iii) the ratio of the  post-transaction  fair market value per share subject to
the option to exercise price per share is the same as the pre-transaction ratio.
For this purpose, the post-transaction  fair market value of Adecco Common Stock
shall be the average of the closing  prices on the Swiss Stock  Exchange for the
five trading days immediately  preceding the Effective Time (converted into U.S.
Dollars at the Federal  Reserve's  Noon Buying Rate for U.S.  Dollars and CHF on
each of such days as determined  pursuant to  instructions  for Form 20-F of the
Securities Exchange Commission (the "SEC")), and the pre-transaction fair market
value of the Olsten  Common Stock shall be the average of the closing  prices on
the New York Stock  Exchange (the "NYSE") for the five trading days  immediately
preceding the Effective Time. If  appropriate,  the exercise price of the Olsten
Options, as adjusted,  shall be converted into CHF at the Federal Reserve's Noon
Buying Rate for U.S. Dollars and CHF on the Effective Date.

          (c) Effective as of the Effective Time, all Olsten Options held by OHS
Employees (as defined in the Employee  Benefits  Allocation  Agreement) shall be
assumed  by OHS and,  at the  election  of OHS,  either  retired,  to the extent
permitted by the Olsten Plans and applicable option agreements,  in exchange for
cash, or converted into options to purchase OHS shares on terms set forth by the
OHS Board of Directors (or a committee thereof),  in its discretion,  subject to
the Olsten Plans and applicable option agreements.

          (d) Without limiting the foregoing and except as otherwise provided in
clauses (b) and (c) above,  the duration and other terms of each adjusted Olsten
Options immediately after the Effective Time (unless otherwise agreed in writing
by the optionee  with respect to a particular  option)  shall be the same as the
corresponding Olsten Option that were in effect immediately before the Effective
Time,  except  that all  references  to  Olsten  in the  Olsten  Plans  (and the
corresponding  references in each option  agreement  documenting each such stock
option) shall be deemed to be references to Adecco or OHS, as applicable.

          (e) As soon as  practicable  after the  Effective  Time,  Adecco shall
deliver to optionees  appropriate  notices setting forth such optionee's  rights
pursuant to the adjusted Olsten Options referenced in clause (b) above.

          (f) Adecco shall take all  corporate  action  necessary to reserve for
issuance a sufficient  number of shares of Adecco Common Stock for delivery upon
exercise of stock options referenced in clause (b) above. As soon as practicable
after the Effective Time, Adecco shall file registration statements on Form S-8,
or another  appropriate  form, as the case may be (or any successor form),  with
respect to the shares of Adecco Common Stock subject to such options.

          (g) Subject to Adecco's  performance  of its  obligations in the first
sentence of clause (f) above,  Olsten,  prior to the Effective Time,  shall take
all corporate action necessary to cause all outstanding  Olsten Options to cease
to represent any claim on the equity of Olsten.

          (h) Olsten agrees to cooperate  with Adecco to develop and implement a
program to be effective at the Effective Time,  whereby  out-of-the money Olsten
Options  will,  with  the  consent  of  the  several  holders,  be  replaced  or
restructured  with  appropriate  employee  incentives,   or  terminated  for  an
equitable  amount.  As to  such  Olsten  Options  which  are  not  so  replaced,
restructured  or  terminated,  Olsten will, to the extent  allowed by the Olsten
Plans, terminate such options at the Effective Time.

          (i) At and after the Effective  Time, the Quantum Debt shall no longer
be exchangeable for shares of Olsten Class B Stock, but instead shall thereafter
be exchangeable,  upon surrender of the instrument  evidencing such Quantum Debt
to OHS,  into the  Closing  Consideration  that would  have been  payable to the
holder of such instrument,  had such instrument been surrendered in exchange for
Olsten Class B Stock  immediately  prior to the Effective Time as if such holder
had made a  Non-Election.  Adecco shall take all corporate  action  necessary to
reserve for issuance a sufficient  number of Adecco ADSs for issuance to holders
of Quantum Debt  surrendering the instruments  evidencing such Quantum Debt and,
upon payment by OHS of the fair market value of such Adecco ADSs,  shall provide
such Adecco ADSs to OHS in satisfaction of such exchange  obligation.  After the
Effective  Time,  the  Quantum  Debt shall cease to  represent  any claim on the
equity of Olsten.

          Section 2.06 Fractional Shares. Notwithstanding any other provision of
this Agreement,  each holder of shares of Olsten Common Stock who upon surrender
of  all of the  Certificates  of  such  holder  would  be  entitled  to  receive
fractional shares of Adecco Common Stock,  Adecco ADSs or OHS Common Stock shall
receive,  in lieu of such  fractional  shares,  cash in an amount  equal to such
fraction  multiplied by the Market Value of Adecco Common Stock,  Adecco ADSs or
OHS Common Stock,  as  applicable.  With respect to Adecco ADSs,  "Market Value"
shall mean the arithmetic average of the last reported sale price of Adecco ADSs
as  reported  on  the  National  Association  of  Securities  Dealers  Automated
Quotation  System  ("NASDAQ") for the five (5)  consecutive  trading days ending
with the last trading day prior to the  Effective  Time.  With respect to Adecco
Common  Stock,  "Market  Value"  shall mean the  arithmetic  average of the last
reported  sale  price of Adecco  Common  Stock as  reported  on the Swiss  Stock
Exchange for the five (5) consecutive  trading days ending with the last trading
day prior to the  Effective  Time.  With  respect to OHS Common  Stock,  "Market
Value" shall mean the last  reported  sale price of OHS Common Stock as reported
on a  national  securities  exchange  or NASDAQ on the first  full  trading  day
following the Effective Time. All references in this Agreement to Adecco ADSs or
Adecco Common Stock to be issued as Stock  Consideration  or OHS Common Stock to
be issued as Split-Off Consideration shall be deemed to include any cash in lieu
of fractional shares of Adecco ADSs, Adecco Common Stock or OHS Common Stock, as
applicable, payable pursuant to this Section 2.06.

          Section 2.07 Dissenting Shares. (a)  Notwithstanding  anything in this
Agreement to the contrary,  Olsten Common Stock which is issued and  outstanding
immediately prior to the Effective Time and which is held by Olsten stockholders
who have not voted such shares in favor of the Merger,  who shall have delivered
a written  demand for  appraisal  of such shares of Olsten  Common  Stock in the
manner provided in the Delaware Act and who, as of the Effective Time, shall not
have effectively withdrawn or lost such right to appraisal ("Dissenting Shares")
shall  not be  converted  into or  represent  a right  to  receive  the  Closing
Consideration  pursuant to Section 2.01 hereof, but the holders thereof shall be
entitled  only to such rights as are granted by Section 262 of the Delaware Act.
Each holder of Dissenting Shares who becomes entitled to payment for such shares
pursuant to Section 262 of the Delaware Act shall receive payment  therefor from
the  Surviving  Corporation  in  accordance  with the  Delaware  Act;  provided,
however,  that if (i) any such holder of Dissenting  Shares shall have failed to
establish his/her  entitlement to appraisal rights as provided in Section 262 of
the  Delaware  Act,  (ii)  any such  holder  of  Dissenting  Shares  shall  have
effectively  withdrawn  his/her  demand for  appraisal  of such shares of Olsten





                                       11
<PAGE>
Common Stock or lost his/her right to appraisal  and payment for his/her  shares
of Olsten  Common Stock under  Section 262 of the Delaware Act or (iii)  neither
any holder of Dissenting Shares nor the Surviving Corporation shall have filed a
petition  demanding a determination of the value of all Dissenting Shares within
the time provided in Section 262 of the Delaware Act, such holder or holders, as
the case may be,  shall  forfeit the right to  appraisal of such shares and each
such share shall thereupon be deemed to have been converted, as of the Effective
Time, into and represent the right to receive from the Surviving Corporation the
Closing  Consideration,  without interest  thereon,  as provided in Section 2.01
hereof.  In such case, the Surviving  Corporation will provide to such holder or
holders, the Split-Off Consideration with respect to such shares.

          (b) Notice of Appraisal  Demands.  Olsten shall give Adecco and Merger
Sub (i) prompt  notice of any written  demands  for  appraisal,  withdrawals  of
demands for appraisal and any other  instruments  served pursuant to Section 262
of the Delaware Act  received by Olsten and (ii) the  opportunity  to direct all
negotiations and proceedings with respect to demands for appraisal under Section
262 of the Delaware Act. Olsten shall not, except with the prior written consent
of  Adecco,  voluntarily  make any  payment  with  respect  to any  demands  for
appraisal or offer to settle or settle any such demands.

          Section 2.08 Lost  Certificates.  If any  Certificate  shall have been
lost,  stolen or destroyed,  upon the making of an affidavit of that fact by the
person  claiming  such  Certificate  to be lost,  stolen or  destroyed  and,  if
required  by the  Exchange  Agent,  the posting by such person of a bond in such
reasonable  amount as Adecco may direct as indemnity  against any claim that may
be made against it with respect to such Certificate,  the Surviving  Corporation
or Olsten will issue in exchange for such lost, stolen or destroyed  Certificate
the Closing Consideration in respect thereof pursuant to this Agreement.

          Section 2.09  Withholding  Rights.  Each of Olsten and Adecco shall be
entitled  to  deduct  and  withhold  from the  consideration  otherwise  payable
pursuant to this  Agreement  to any holder of former  Olsten  Common  Stock such
amounts as may be required  to be  deducted  and  withheld  with  respect to the
making of such payment under the Internal  Revenue Code of 1986, as amended (the
"Code"),  or under any  provision  of state,  local or foreign  tax law.  To the
extent  that  amounts are so withheld  and paid over to the  appropriate  taxing
authority,  such  withheld  amounts  shall be treated  for all  purposes of this
Agreement  as having  been  paid to the  holder of the  Olsten  Common  Stock in
respect of which such deduction and withholding was made.

                                  ARTICLE III.

                         REPRESENTATIONS AND WARRANTIES
                            OF Adecco AND MERGER SUB

          Subject to the disclosure schedule delivered by Adecco to Olsten at or
prior to the execution of this  Agreement (the "Adecco  Disclosure  Statement"),
the section  numbers of which are numbered to correspond to the sections of this
Agreement to which they  relate,  each of Adecco and Merger Sub  represents  and
warrants to Olsten as follows:








                                       12
<PAGE>
          Section  3.01   Organization,   Etc.  Adecco  is  a  corporation  duly
organized,  validly  existing and in good standing under the laws of Switzerland
and has all  requisite  power  and  authority  to own,  lease  and  operate  its
properties and assets and to carry on its business as it is now being conducted.
Adecco is duly qualified as a foreign corporation to do business, and is in good
standing in each  jurisdiction  where the  character  of its  properties  owned,
leased or  operated  or the nature of its  activities  makes such  qualification
necessary, except for failures to be so qualified or in good standing that would
not,  individually  or in the aggregate,  have a material  adverse effect on the
business, results of operations, assets or condition (financial or otherwise) of
Adecco and its  Subsidiaries  taken as a whole,  other than any change or effect
arising out of or  resulting  from general  economic  conditions  or  conditions
affecting the staffing  services industry (an "Adecco Material Adverse Effect").
Neither  Adecco nor Merger Sub is in violation of any of the  provisions  of its
organizational  documents.  Complete  and correct  copies of the  organizational
documents,  as  currently  in  effect,  of Adecco  and Merger Sub have been made
available to Olsten.

          Section  3.02  Authority.  Each of  Adecco  and  Merger  Sub has  full
corporate power and authority to execute and deliver this Agreement and, subject
to approval of the Adecco Stockholder  Proposals by the holders of Adecco Common
Stock at the Adecco  Special  Meeting,  to  consummate  the Merger and the other
transactions  contemplated  hereby. The execution and delivery of this Agreement
and the  consummation  of the  Merger  and the other  transactions  contemplated
hereby  have been duly and  validly  authorized  by the Boards of  Directors  of
Adecco and Merger Sub, and by Adecco as the sole  shareholder of Merger Sub, and
no other corporate proceedings on the part of Adecco or Merger Sub are necessary
to  authorize   this  Agreement  or  to  consummate  the  Merger  or  the  other
transactions contemplated hereby (other than the approval of and the adoption of
the  Adecco  Stockholder   Proposals  at  the  Adecco  Special  Meeting  or  any
adjournment thereof by the requisite holders of the outstanding shares of Adecco
Common Stock).  This Agreement has been duly and validly  executed and delivered
by each of Adecco and Merger Sub and, assuming the due authorization,  execution
and delivery hereof by Olsten, constitutes a valid and binding agreement of each
of  Adecco  and  Merger  Sub,  enforceable  against  Adecco  and  Merger  Sub in
accordance with its terms,  except to the extent that its  enforceability may be
limited by  applicable  bankruptcy,  insolvency,  reorganization,  moratorium or
other laws  affecting  the  enforcement  of  creditors'  rights  generally or by
general equitable  principles.  Adecco has full corporate power and authority to
execute and deliver the Separation Agreement.  The execution and delivery of the
Separation  Agreement  have been  duly and  validly  authorized  by the Board of
Directors of Adecco,  and no other  corporate  proceedings on the part of Adecco
are necessary to authorize the Separation  Agreement.  The Separation  Agreement
has been duly and validly executed and delivered by Adecco and, assuming the due
authorization,  execution and delivery thereof by Olsten and OHS,  constitutes a
valid and binding agreement of Adecco,  enforceable against Adecco in accordance
with its terms,  except to the extent that its  enforceability may be limited by
applicable  bankruptcy,  insolvency,  reorganization,  moratorium  or other laws
affecting the enforcement of creditors' rights generally or by general equitable
principles.

          Section  3.03  Consents;   No  Violations,   Etc.  (a)  No  filing  or
registration  with,  or  permit,  authorization,  consent  or  approval  of,  or
notification  or disclosure to, any United States  (federal,  state or local) or
foreign  government,  or governmental,  regulatory or administrative  authority,
agency or  commission  (a  "Governmental  Authority"),  court or third  party is
required by Adecco or Merger Sub in  connection  with the execution and delivery
of  this  Agreement  and,  as  applicable,  the  Separation  Agreement,  or  the
consummation  of the  Merger  and the other  transactions  contemplated  hereby,
except   (i)  in   connection   with   the   applicable   requirements   of  the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act")
and applicable  foreign antitrust or other similar laws, (ii) in connection with
the  provisions of the  Securities  Act of 1933,  as amended,  and the rules and
regulations  promulgated  thereunder (the  "Securities  Act") and the Securities
Exchange  Act of 1934,  as amended,  and the rules and  regulations  promulgated
thereunder  (the  "Exchange  Act"),  (iii)  the  filing  of  appropriate  merger
documents  as required  by the  Delaware  Act,  (iv) such  consents,  approvals,
orders, permits, authorizations,  registrations, declarations and filings as may
be  required  under the Blue Sky laws of various  states and (v) such  consents,
approvals,  orders,  permits,  authorizations,  registrations,  declarations and
filings which will have been made or obtained  prior to the  Effective  Time and
will then be in full force and effect.

          (b) Assuming  that all  filings,  permits,  authorizations,  consents,
disclosures  and approvals  required  prior to the Effective Time have been duly
made or obtained as contemplated by Section 3.03(a), the execution, delivery and
performance of this Agreement and the Separation  Agreement and the consummation
of the Merger and the other transactions  contemplated hereby by Adecco will not
(i)  subject to approval  by the  holders of Adecco  Common  Stock at the Adecco
Special Meeting, violate any provision of the organizational documents of Adecco
or Merger Sub, (ii) violate any statute, rule, regulation, injunction, judgment,
writ,  order or decree of any  Governmental  Authority  or court  applicable  to
Adecco or Merger Sub or by which Adecco or Merger Sub or any of their properties
are bound or (iii)  result in a violation or breach of, or  constitute  (with or
without  due  notice  or lapse of time or both) a  default  (or give rise to any
right of  termination,  cancellation,  acceleration,  redemption or  repurchase)
under,  any of the  terms,  conditions  or  provisions  of any (x)  note,  bond,
mortgage, indenture or deed of trust relating to indebtedness for borrowed money
or (y) license,  lease,  agreement or other  instrument  or  obligation to which
Adecco  or  Merger  Sub is a party  or by which  either  of them or any of their
properties or assets may be bound, excluding from the foregoing clauses (ii) and
(iii)(y)  violations,   breaches  or  defaults  that,  individually  or  in  the
aggregate,  would  not  either  impair  Adecco's  or  Merger  Sub's  ability  to
consummate the Merger or the other transactions  contemplated  hereby or have an
Adecco Material Adverse Effect.

          Section 3.04  Capitalization.  At July 4, 1999, the authorized capital
stock of Adecco consists of 19,769,082  shares of Adecco Common Stock and 24,500
shares of Participation Certificates (Class A), nominal value 2.0 CHF per share.
As of July 4, 1999,  there were 17,197,948  shares of Adecco Common Stock issued
and  outstanding  and 67,180  shares of Adecco  Common  Stock  held in  Adecco's
treasury.  All issued and outstanding shares of capital stock of Adecco are duly
authorized and validly issued,  fully paid and nonassessable.  The Adecco Common
Stock to be issued in accordance with Section 2.01 hereof,  when so issued, will
be duly and validly  authorized  and, when Adecco ADSs  representing  the Adecco





                                       14
<PAGE>
Common  Stock to be  issued  hereunder  are  issued,  the ADSs  will be duly and
validly issued,  fully paid and nonassessable and free of preemptive rights with
respect thereto. Upon issuance by the Depositary of ADRs evidencing ADSs against
the deposit of Adecco  Common Stock in respect  thereof in  accordance  with the
provisions of the Deposit  Agreement,  such ADRs will be duly and validly issued
and the persons in whose names the ADRs are  registered  will be entitled to the
rights specified  therein and in the Deposit  Agreement.  Other than pursuant to
the options to acquire  Adecco Common Stock,  there has not been any issuance of
capital  stock of  Adecco  since  July 4,  1999.  Adecco is a  "foreign  private
issuer," as such term is defined in Rule 3b-4(c) under the Exchange Act.

          Section 3.05 SEC and Other  Filings.  (a) Adecco has timely filed with
the SEC, any similar  foreign  regulatory  authority  and any stock  exchange on
which Adecco Common Stock or Adecco ADRs are listed all required forms, reports,
registration statements and documents required to be filed by it with the SEC or
such other authority since January 1, 1997 (collectively, the "Adecco Reports"),
all of which  complied as to form when filed in all material  respects  with the
applicable  provisions of the Securities Act, the Exchange Act or the applicable
laws or  regulations  of any such  authority,  as the  case may be.  As of their
respective  dates,  the Adecco  Reports  (including  all exhibits and  schedules
thereto and  documents  incorporated  by reference  therein) did not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements  therein,  in light of the
circumstances under which they were made, not misleading. All documents required
to be filed as  exhibits  to the  Adecco  Reports  have been so  filed.  None of
Adecco's  Subsidiaries is required to file any forms, reports or other documents
with the SEC.

          (b) Adecco will deliver to Olsten,  as soon as they become  available,
true and  complete  copies of any  report or  statement  mailed by Adecco to its
securityholders  generally  or filed by it with the  SEC,  any  similar  foreign
regulatory  authority  or any stock  exchange on which  Adecco  Common  Stock or
Adecco ADRs are listed,  in each case subsequent to the date hereof and prior to
the Effective Time. As of their  respective  dates,  such reports and statements
(excluding any information  therein provided by Olsten, as to which Adecco makes
no  representation)  will not contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to make
the statements  therein,  in the light of the circumstances under which they are
made,  not  misleading  and  will  comply  in all  material  respects  with  all
applicable  requirements of law. The audited  consolidated  financial statements
and  unaudited  consolidated  interim  financial  statements  of Adecco  and its
Subsidiaries  required to be  included  or  incorporated  by  reference  in such
reports and  statements  (if any) will be prepared in accordance  with U.S. GAAP
(as defined below) and will fairly present the consolidated  financial  position
of Adecco and its  Subsidiaries  as of the dates  thereof  and the  consolidated
results of  operations  and  consolidated  cash flows for the periods then ended
(subject, in the case of any unaudited interim financial  statements,  to normal
year-end  adjustments and to the extent they may not include footnotes or may be
condensed or summary statements).

          Section 3.06 Financial Statements.  The audited consolidated financial
statements of Adecco and its Subsidiaries  included or incorporated by reference
in any of the Adecco  Reports have been  prepared in accordance  with  generally
accepted  accounting  principles in the United  States,  applied on a consistent





                                       15
<PAGE>
basis  during the  periods  involved  (except as may be  indicated  in the notes
thereto)  ("U.S.  GAAP"),  and  fairly  present  in all  material  respects  the
consolidated  financial  position of Adecco and its Subsidiaries as of the dates
thereof and the consolidated  results of operations and consolidated  cash flows
for the periods then ended, and such audited  consolidated  financial statements
are  accompanied  by  an  unqualified   auditors'  report  thereon  by  Adecco's
independent public accountants.  The unaudited  consolidated  balance sheets and
statements  of  operations  as of July 4,  1999 of Adecco  and its  Subsidiaries
provided  to Olsten  have been  prepared  in  accordance  with  U.S.  GAAP.  The
Consolidated  Balance Sheet as at January 3, 1999 of Adecco and its Subsidiaries
contained in such financial statements is hereinafter referred to as the "Adecco
Balance Sheet."

          Section  3.07  Absence  of  Undisclosed  Liabilities.  As of the  date
hereof,  neither  Adecco  nor any of its  Subsidiaries  has any  liabilities  or
obligations of any nature, whether absolute, accrued,  unmatured,  contingent or
otherwise,  or  any  unsatisfied  judgments  or  any  unusual  or  extraordinary
commitments, except for (i) the liabilities recorded on the Adecco Balance Sheet
and/or  reflected  in  the  notes  thereto,  (ii)  liabilities  and  obligations
disclosed in any Adecco Report filed since January 3, 1999 and prior to the date
of this Agreement or in the unaudited  consolidated balance sheets as of July 4,
1999 of Adecco and its Subsidiaries  provided to Olsten,  (iii)  liabilities and
obligations  incurred  since January 3, 1999 in the ordinary  course of business
consistent  with past  practice,  which are not  unusual in nature or amount and
which  would not,  individually  or in the  aggregate,  have an Adecco  Material
Adverse Effect and (iv) liabilities or obligations that,  individually or in the
aggregate, would not have an Adecco Material Adverse Effect.

          Section  3.08  Absence  of Changes  or  Events.  From  January 3, 1999
through the date of this Agreement and except as set forth in the Adecco Reports
filed  prior to the date  hereof (a) there has been no Adecco  Material  Adverse
Effect,  (b) Adecco and its  Subsidiaries  have conducted their business only in
the  ordinary  course and (c) neither  Adecco nor any of its  Subsidiaries  has,
directly or indirectly:

    (a)   purchased  or otherwise  acquired,  or agreed to purchase or otherwise
acquire,  any shares of capital stock of Adecco or any of its  Subsidiaries,  or
any  options,  warrants  or other  equity  securities  of  Adecco  or any of its
Subsidiaries,  in each case, other than purchases or acquisitions (or agreements
with respect  thereto) of minority  interests or made in the ordinary  course of
business  consistent  with past  practice,  or  declared,  set aside or paid any
dividend or otherwise made a distribution (whether in cash, stock or property or
any combination thereof) in respect of its capital stock;

    (b)   instituted any significant change in accounting methods, principles or
practices affecting its assets,  liabilities or business,  except insofar as may
be appropriate to conform to changes in law or U.S. GAAP; or

    (c)   agreed to do any of the things described in the preceding  clauses (a)
or (b).

<PAGE>
          Section  3.09  Litigation.  There  is no (i)  claim,  action,  suit or
proceeding  pending or, to the best of Adecco's  knowledge,  threatened  against
Adecco or any of its Subsidiaries before any court or governmental or regulatory
authority or body or arbitration tribunal or (ii) outstanding  judgment,  order,
writ,  injunction  or decree of any court,  governmental  agency or  arbitration
tribunal in a proceeding  to which  Adecco,  any of its  Subsidiaries  or any of
their respective  assets was or is a party,  except,  in the case of clauses (i)
and (ii) above,  such as would not,  individually  or in the  aggregate,  either
impair  Adecco's or Merger Sub's ability to  consummate  the Merger or the other
transactions contemplated hereby or have an Adecco Material Adverse Effect.

          Section  3.10  Compliance  with  Laws.  Neither  Adecco nor any of its
Subsidiaries has violated or failed to comply with any statute,  law, ordinance,
regulation, rule or order of any Governmental Authority, or any judgment, decree
or order of any court, applicable to its business or operations,  except for any
such  violations or failures to comply that,  individually  or in the aggregate,
would not either  impair  Adecco's or Merger  Sub's  ability to  consummate  the
Merger or the other transactions  contemplated hereby or have an Adecco Material
Adverse Effect.

          Section  3.11  Taxes.  Adecco  and each of its  Subsidiaries  have (i)
timely  filed all Tax Returns  required to be filed by them (taking into account
extensions) and all such Tax Returns were complete,  correct and accurate in all
material  respects,  (ii)  timely  paid  all  Taxes  shown to be due on such Tax
Returns,  (iii)  timely  paid all  Taxes for  which a notice  of  assessment  or
collection has been received  (other than amounts being  contested in good faith
by appropriate  proceedings and properly  accrued in accordance with U.S. GAAP),
except in the case of clause (i), (ii) or (iii) for any such filings or payments

                                  ARTICLE IV.

                    REPRESENTATIONS AND WARRANTIES OF OLSTEN

          Subject to the disclosure  schedule  delivered by Olsten to Adecco and
Merger  Sub  at or  prior  to the  execution  of  this  Agreement  (the  "Olsten
Disclosure Statement"),  the section numbers of which are numbered to correspond
to the section numbers of this Agreement to which they relate, Olsten represents
and warrants to Adecco and Merger Sub as follows:

          Section  4.01   Organization,   Etc.  Olsten  is  a  corporation  duly
organized,  validly existing and in good standing under the laws of the state of
Delaware and has all requisite power and authority to own, lease and operate its
properties and assets and to carry on its business as it is now being conducted.
Olsten is duly qualified as a foreign corporation to do business, and is in good
standing,  in each  jurisdiction  where the character of its  properties  owned,
leased or  operated  or the nature of its  activities  makes such  qualification
necessary, except for failures to be so qualified or in good standing that would
not,  individually  or in the aggregate,  have a material  adverse effect on the
business, results of operations, assets or condition (financial or otherwise) of
(i)  Olsten  and its  Subsidiaries  taken as a  whole,  or (ii)  Olsten  and the
Retained Subsidiaries, taken as a whole, other than any change or effect arising
out of or resulting from general economic conditions or conditions affecting the
staffing services  industry (a "Olsten Material Adverse Effect").  Olsten is not
in violation of any of the provisions of its organizational documents.  Complete
and correct copies of the organizational  documents,  as currently in effect, of
Olsten have been made available to Adecco.

          Section 4.02 Authority.  Olsten has full corporate power and authority
to execute and deliver this Agreement and the Separation  Agreement and, subject
to approval by the requisite  holders of the outstanding  shares of Olsten Stock
and Olsten  Class B Stock,  voting  together  as a single  class,  at the Olsten
Special  Meeting,  to  consummate  the  Merger,  the  Split-Off  and  the  other
transactions contemplated hereby and thereby. The execution and delivery of this
Agreement and the Separation  Agreement and the consummation of the Merger,  the
Split-Off and the other transactions  contemplated  hereby and thereby have been
duly and validly  authorized  by the Board of Directors of Olsten,  and no other
corporate  proceedings  on the part of Olsten are  necessary to  authorize  this
Agreement or the Separation Agreement or to consummate the Merger, the Split-Off
and the other  transactions  contemplated  hereby and  thereby  (other  than the
approval  of  and  adoption  of  this  Agreement,   the  Merger  and  the  other
transactions   contemplated   hereby  at  the  Olsten  Special  Meeting  or  any
adjournment thereof by the requisite holders of the outstanding shares of Olsten
Common Stock and Olsten Class B Stock,  voting together as a single class). Each
of this  Agreement  and the  Separation  Agreement  has been  duly  and  validly
executed and delivered by Olsten and, in the case of Separation Agreement,  OHS,
and assuming the due authorization,  execution and delivery hereof by Adecco and
Merger Sub, in the case of the Merger Agreement, constitutes a valid and binding
agreement  of  Olsten  and,  in the  case  of  the  Separation  Agreement,  OHS,
enforceable against Olsten, and in the case of the Separation Agreement, OHS, in
accordance with its terms,  except to the extent that its  enforceability may be
limited by  applicable  bankruptcy,  insolvency,  reorganization,  moratorium or
other laws  affecting  the  enforcement  of  creditors'  rights  generally or by
general equitable principles.

          Section  4.03  Consents;   No  Violations,   Etc.  (a)  No  filing  or
registration  with,  or  permit,  authorization,  consent  or  approval  of,  or
notification or disclosure to, any Governmental Authority,  court or third party
is required by Olsten or OHS in  connection  with the  execution and delivery of
this Agreement and the Separation Agreement or the consummation by Olsten of the
Merger and the  consummation  by Olsten and OHS of the  Split-Off  and the other
transactions  contemplated hereby and thereby, except (i) in connection with the

similar laws,  (ii) in connection  with the provisions of the Securities Act and
the Exchange Act, (iii) the filings of appropriate  merger documents as required
by  the  Delaware  Act,  (iv)  such  consents,   approvals,   orders,   permits,

the Blue Sky laws of various  states and (v) such consents,  approvals,  orders,
permits, authorizations, registrations, declarations and filings which will have
been made or obtained prior to the Effective Time and will then be in full force
and effect.

          (b)  Assuming  that all  filings,  permits,  authorization,  consents,
disclosures  and approvals  required  prior to the Effective Time have been duly
made or obtained as contemplated by Section 4.03(a),  the execution and delivery
of this Agreement and the Separation Agreement and the consummation by Olsten of
the  Merger  and  Olsten  and OHS of the  Split-Off  and the other  transactions
contemplated  hereby and thereby will not (i) subject to obtaining  the approval
of the requisite  holders of the  outstanding  shares of Olsten Common Stock and
Olsten Class B Stock,  voting together as a single class,  violate any provision
of the  organizational  documents  of  Olsten or any of its  Subsidiaries,  (ii)
violate any statute,  rule,  regulation,  injunction,  judgment,  writ, order or
decree of any Governmental Authority or court applicable to Olsten or any of its
Subsidiaries  or by  which  Olsten,  any of  its  Subsidiaries  or any of  their
properties  are bound or (iii) result in a violation or breach of, or constitute
(with or without due notice or lapse of time or both) a default (or give rise to
any right of termination, cancellation,  acceleration, redemption or repurchase)
under,  any of the  terms,  conditions  or  provisions  of any (x)  note,  bond,
mortgage, indenture or deed of trust relating to indebtedness for borrowed money
or Governmental Settlement Agreement (as defined in the Separation Agreement) or
(y) license,  lease, agreement or other instrument or obligation to which Olsten
or any of its  Subsidiaries  is a party or by which  any of them or any of their
properties or assets may be bound, excluding from the foregoing clauses (ii) and
(iii)(y)  violations,   breaches  or  defaults  that,  individually  or  in  the
aggregate,  would not either impair Olsten's or OHS', as applicable,  ability to
consummate the Merger or Split-Off or the other transactions contemplated hereby
or by the Separation Agreement or have an Olsten Material Adverse Effect.

          Section 4.04  Capitalization.  The authorized  capital stock of Olsten
consists of  110,000,000  shares of Olsten  Stock,  50,000,000  shares of Olsten
Class B Stock and 250,000 shares of preferred  stock,  par value $.10 per share.
As of April 4, 1999, there were 68,255,667  shares of Olsten Stock  outstanding,
13,068,973 shares of Olsten Class B Stock  outstanding,  45,700 shares of Olsten
Stock held in Olsten's  treasury  and  7,475,040  shares of Olsten  Common Stock
(including 5,731,342 shares of Olsten Stock and 1,743,698 shares of Olsten Class
B Stock) reserved for issuance upon the exercise of options  theretofore granted
pursuant to the Olsten Plans and upon conversion of the Quantum Debt (as defined
in the Separation Agreement). All issued and outstanding shares of capital stock
of Olsten are duly authorized and validly issued, fully paid,  nonassessable and





                                       20
<PAGE>
free of  preemptive  rights with  respect  thereto.  Section  4.04 of the Olsten
Disclosure  Statement  lists each  Olsten Plan and each  outstanding  option and
stock grant as of August 12, 1999,  the number of shares of Olsten  Common Stock
to be received upon exercise  thereof and the exercise price of each such option
(the "Olsten  Common  Stock  Equivalents").  Except for the Olsten  Common Stock
Equivalents  and the  Quantum  Debt,  there  are no  options,  warrants,  calls,
subscriptions,  or other rights,  agreements or commitments obligating Olsten to
issue,  transfer  or sell any  shares  of  capital  stock of Olsten or any other
securities  convertible  into or evidencing  the right to subscribe for any such
shares. Other than stock, if any, issued pursuant to the Olsten Plans, stock, if
any,  issued upon  conversion of the Quantum Debt and stock, if any, issued upon
exercise of stock options or the vesting of stock grants  pursuant to the Olsten
Common Stock  Equivalents,  there has not been any issuance of capital  stock of
Olsten since August 12, 1999. There are no outstanding stock appreciation rights
with respect to the capital stock of Olsten.  At and after the  Effective  Time,
none of the options or warrants exercisable for or other securities  convertible
into shares of capital stock of Olsten shall, then or thereafter, continue to be
so exercisable or convertible into capital stock or other claim on the equity of
Olsten.

          Section 4.05 SEC Filings. (a) Olsten has timely filed with the SEC and
any stock  exchange on which Olsten  Common Stock is listed all required  forms,
reports,  registration  statements and documents required to be filed by it with
the SEC or such other authority since January 1, 1996 (collectively, the "Olsten
SEC  Reports"),  all of which  complied  as to form when  filed in all  material
respects with the  applicable  provisions of the  Securities Act or the Exchange
Act or the applicable laws or regulations of any such authority, as the case may
be. As of their respective dates, the Olsten SEC Reports (including all exhibits
and schedules thereto and documents  incorporated by reference  therein) did not
contain any untrue statement of a material fact or omit to state a material fact
required to be stated  therein or necessary to make the statements  therein,  in
light of the circumstances under which they were made, not misleading. Except as
set forth in Section 4.05(a) of the Olsten Disclosure  Statement,  all documents
required to be filed as  exhibits to the Olsten SEC Reports  have been so filed.
None of Olsten's  subsidiaries  is required to file any forms,  reports or other
documents with the SEC.

          (b) Olsten  will  deliver to Adecco as soon as they  become  available
true and  complete  copies of any  report or  statement  mailed by Olsten to its
securityholders  generally or filed by it with the SEC, in each case  subsequent
to the date  hereof  and prior to the  Effective  Time.  As of their  respective
dates, such reports and statements  (excluding any information  therein provided
by Adecco,  as to which  Olsten  makes no  representation)  will not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements  therein,  in the light of
the  circumstances  under which they are made, not misleading and will comply in
all  material  respects  with all  applicable  requirements  of law. The audited
consolidated  financial statements and unaudited  consolidated interim financial
statements  of Olsten and its  Subsidiaries  to be included or  incorporated  by
reference in such reports and  statements  will be prepared in  accordance  with
U.S. GAAP and  regulations  of the SEC  applicable to public  companies and will
fairly  present  the   consolidated   financial   position  of  Olsten  and  its
Subsidiaries as of the dates thereof and the consolidated  results of operations
and consolidated cash flows for the periods then ended (subject,  in the case of
any unaudited interim financial  statements,  to normal year-end adjustments and
to the extent  they may not include  footnotes  or may be  condensed  or summary
statements).

tribunal in a proceeding  to which  Olsten,  any of its  Subsidiaries  or any of

Agreement or have an Olsten Material Adverse Effect.

          Section 4.10 Subsidiaries and Investments.  (a) Section 4.10(a) of the

stock or share capital of each  Subsidiary of Olsten are validly  issued,  fully
paid and  nonassessable,  and those owned by Olsten or by a Subsidiary of Olsten
are owned  free and clear of any  liens,  claims or  encumbrances.  There are no
options,   warrants,  calls,   subscriptions  or  other  rights,  agreements  or
commitments  obligating any of the Subsidiaries of Olsten to issue,  transfer or
sell any shares of its capital  stock or other  securities  convertible  into or
evidencing the right to subscribe for any such shares.

          (b) Section 4.10(b) of the Olsten  Disclosure  Statement  lists, as of

under the Exchange Act.

          (c)  Section  4.10(c) of the  Olsten  Disclosure  Statement  lists all

interests.

any  statute,  law,  ordinance,  regulation,  rule or order of any  Governmental
Authority, or any judgment,  decree or order of any court, applicable to it, its
business or  operations  or by which it, its business or  operations  are bound,
except for any such  violations or failures to comply that,  individually  or in
the  aggregate,  would not impair  Olsten's or OHS' (as  applicable)  ability to
consummate  the Merger,  the Split-Off and the other  transactions  contemplated
hereby or by the Separation Agreement or have an Olsten Material Adverse Effect,
(ii) no investigation or review by any Governmental  Authority is pending or, to
Olsten's   knowledge,   has  been  threatened  against  Olsten  or  any  of  its
Subsidiaries,  nor,  to  Olsten's  knowledge,  has  any  Governmental  Authority
indicated by written notice or, to Olsten's knowledge,  otherwise,  an intention
to conduct an investigation of Olsten or any of its Subsidiaries, other than any
such  investigation  which would not,  individually or in the aggregate,  impair
Olsten's or OHS' (as applicable) ability to consummate the Merger, the Split-Off
or the other transactions  contemplated hereby or by the Separation Agreement or
have an Olsten  Material  Adverse  Effect;  (iii) neither  Olsten nor any of its
Subsidiaries is liable, either primarily or jointly and severally with any other
party,  for any fines,  penalties or other amounts  payable to any  Governmental
Authority in an aggregate  amount in excess of  $5,000,000  and (iv) there is no
agreement, judgement,  injunction, order or decree binding upon Olsten or any of
its Subsidiaries which has or could reasonably be expected to have the effect of
prohibiting  or materially  impairing any business  practice of Olsten or any of
its  Subsidiaries,  any acquisition of material property by Olsten or any of its
Subsidiaries,  the conduct of business by Olsten as currently conducted,  or the
Merger or Split-Off or the other transactions contemplated by this Agreement and
the Separation  Agreement.  Other than as disclosed by Olsten to Adecco,  Olsten
and its Subsidiaries are each in compliance,  in all material respects, with all
material laws and  regulations  relating to franchising  and their  relationship
with their franchisees and licensed area representatives.

          (b)  Each  of  Olsten  and its  Subsidiaries  has  such  certificates,
permits, licenses,  franchises,  consents, approvals, orders, authorizations and
clearances from appropriate  Governmental Authorities ("Olsten Licenses") as are
necessary to own,  lease or operate its properties and assets and to conduct its
business in the manner  described  in the Olsten SEC  Reports  and as  presently
conducted  and all such Olsten  Licenses are valid and in full force and effect,
except for any  failures to have any such Olsten  License or any failures of any
such Olsten License to be valid and in full force and effect that,  individually
or in the aggregate,  would not have an Olsten Material Adverse Effect.  Each of
Olsten and its Subsidiaries is, and within the period of all applicable  statues
of limitation  has been, in compliance  with its  obligations  under such Olsten
Licenses and no event has occurred that allows, or after notice or lapse of time
would allow,  revocation or termination of such Olsten Licenses,  except for any
such failures to be in compliance with such  obligations or any such revocations
or terminations that, individually or in the aggregate, would not have an Olsten
Material  Adverse Effect.  Olsten has no knowledge of any facts or circumstances
that could  reasonably be expected to result in an inability of Olsten or any of
its Subsidiaries to renew any Olsten License. Neither the execution and delivery
by Olsten of this Agreement or by Olsten and OHS of the Separation Agreement nor
the consummation of the Merger or the Split-Off or any of the other transactions
contemplated  herein or therein will result in any  revocation or termination of
any Olsten License, except for Olsten Licenses, the revocation or termination of
which  would not,  individually  or in the  aggregate,  have an Olsten  Material
Adverse Effect or impair, in any material respect, the operation of the Retained
Businesses after the Merger.

          Section 4.12  Intellectual  Property  Rights.  To Olsten's  knowledge,
Olsten and its Subsidiaries own or have the right to use all Olsten Intellectual
Property Rights (as defined below)  necessary to the conduct of their respective
businesses,  except for such lack or defects in ownership or possession as would
not,  individually or in the aggregate,  have an Olsten Material Adverse Effect.
There have been no written  claims or  assertions  made by others that Olsten or
any of its Subsidiaries has infringed any material  intellectual property rights
of others in the preceding three year period and, to Olsten's  knowledge,  there
has been no such  infringement by Olsten or any of its Subsidiaries  during this
period except for such  infringements  that,  individually  or in the aggregate,
would not have an Olsten Material Adverse Effect. Olsten has no knowledge of any
infringement of Olsten Intellectual  Property Rights by others,  except for such
infringements that,  individually or in the aggregate,  would not have an Olsten
Material Adverse Effect. All material issued patents,  registered trademarks and
service  marks owned by Olsten or its  Subsidiaries  are  recorded on the public
record in the name of Olsten or its Subsidiaries,  except to the extent that the
failure to be so recorded  would not  materially  impair the  ownership,  use or
protection of such patents, trademarks and service marks .

          Section 4.12 of the Olsten Disclosure Statement contains a list of all
material   patents,   trade  names,   registered   copyrights,   registered  and
unregistered  trademarks  and service marks and  applications  for the foregoing
owned by Olsten or its  Subsidiaries.  Olsten and/or its Subsidiaries have clear
and unencumbered title to the Olsten  Intellectual  Property Rights set forth in
Section  4.12 of the  Olsten  Disclosure  Statement  and such title has not been
challenged  (pending or threatened) by others except for the encumbrances listed
therein.

          "Olsten  Intellectual  Property  Rights" shall mean and include rights
relating to Olsten's or its Subsidiaries,  patents,  trademarks,  service marks,
trade names, copyrights, and all currently pending applications for any thereof,
and  any  inventions,   processes,  trade  secrets,  know-how,   confidentiality
agreements,  consulting agreements, software systems, proprietary field systems,
software licenses or options to obtain rights or licenses.

governmental  authorities  all Tax  Returns  (as such term is defined in Section
3.11)  required  to be filed  through  the date  hereof.  Such Tax  Returns  are
complete, correct and accurate in all respects. Olsten and its Subsidiaries have
delivered to Adecco  complete and accurate copies of all  consolidated  federal,
state and  local  income  or  franchise  Tax  Returns  filed by  Olsten  and its
Subsidiaries for their taxable year ended December 28, 1997.

    (b)        Payment of Taxes.  Olsten and its Subsidiaries  have paid or will
have paid all Taxes for all periods or portions  thereof ending on or before the
Effective Time, or adequate  reserves (in conformity with U.S. GAAP applied on a
consistent  basis and  consistent  with such  entity's past custom and practice)
have been established therefor, and Olsten and its Subsidiaries have no material
liability for Taxes in excess of the amounts so paid or reserves so established.
All Taxes that Olsten and each of its Subsidiaries have been required to collect
or withhold  have been duly  collected or withheld  and, to the extent  required
when  due,  have  been or  will be duly  paid  to the  proper  taxing  or  other
governmental authority.

               (ii) Olsten and its  Subsidiaries  are not parties to or bound by
     any tax sharing, tax indemnity or tax allocation agreement or other similar
     arrangement with any other person or entity (including, without limitation,

    (e)        Additional Representations.

               (i) There are no liens  for Taxes  (other  than for Taxes not yet

     members  of an  affiliated  group of  corporations  within  the  meaning of
     Section 1504 of the Code,  with the exception of the  affiliated  group for
     which  Olsten  is  the  common  parent.  Neither  Olsten  nor  any  of  its
     Subsidiaries,  or any  predecessor  or affiliate of any of them, has become
     liable  (whether  by  contract,  as  transferee  or  successor,  by  law or
     otherwise)  for the Taxes of any other  person  or  entity  under  Treasury
     Regulation  section  1.1502-6 or any similar  provision of state,  local or

               (iv) Neither Olsten nor any of its Subsidiaries is a party to any
     agreement, contract, arrangement or plan that has resulted or would result,

               (v) Olsten and its Subsidiaries have not been "United States real

     the   Code   during   the   applicable    period   specified   in   Section
     897(c)(1)(A)(ii).

               (vi)  Olsten  and  its  Subsidiaries  have  properly   requested,
     received  and  retained  all  necessary  exemption  certificates  and other
     documentation  supporting any claimed exemption or waiver of Taxes on sales
     or other  transactions as to which Olsten and its  Subsidiaries  would have
     been obligated to collect or withhold  Taxes,  except for any failure to do
     so which would not be expected to have a Material  Adverse Effect on Olsten
     and its Subsidiaries taken as a whole.

               (vii)  There  is no  contract,  agreement,  plan  or  arrangement
     covering  any  employee  or  former  employee  of  Olsten  or  any  of  its
     Subsidiaries  (with respect to such employee's  relationship with Olsten or
     the applicable Subsidiary) that, individually or collectively, requires, or
     in  any  prior  period  required,  the  payment  by  Olsten  or  any of its
     Subsidiaries of any amount (i) that is or was not deductible  under Section
     162(a)(1)  or 404 of the Code or (ii) that is or was an  "excess  parachute

contributed  to by  Olsten  or any of its  Subsidiaries  or any of  their  ERISA
Affiliates,  or to which Olsten or any of its Subsidiaries or any of their ERISA

          (b) Olsten has delivered or made available to Adecco true and complete

Benefit Plans and Olsten  Welfare Plans are in  compliance  with the  applicable
provisions  of ERISA,  the Code and other  applicable  laws with  respect to the
Olsten Pension Benefit Plans and Olsten Welfare Plans,  except where the failure
to comply  would  not,  singly  or in the  aggregate  with all  other  failures,
non-compliance, liabilities, transactions, events and other matters that are the
subject of any representation  and warranty under this Section 4.14,  reasonably
be expected to have an Olsten Material Adverse Effect.

<PAGE>
          (d) All  contributions  to, and  payments  from,  the  Olsten  Pension
Benefit Plans which are required to have been made in accordance with the Olsten
Pension Benefit Plans and, when applicable,  Section 302 of ERISA or Section 412
of the Code  have been  timely  made,  except  where  the  failure  to make such
contributions  or  payments  on a  timely  basis  would  not,  singly  or in the
aggregate with all other failures,  non-compliance,  liabilities,  transactions,
events and other matters that are the subject of any representation and warranty
under this  Section  4.14,  reasonably  be expected  to have an Olsten  Material
Adverse Effect.

          (e) The Olsten Pension Benefit Plans intended to qualify under Section
401 of the Code have been determined by the Internal Revenue Service (the "IRS")
to be so  qualified  and nothing has occurred  with respect to the  operation of
such Olsten  Pension  Benefit Plans which would  reasonably be expected to cause
the loss of such  qualification  or exemption or the  imposition of any material
liability, penalty or tax under ERISA or the Code.

          (f) There  are (i) no  investigations  pending,  to the  knowledge  of
Olsten, by any governmental entity involving the Olsten Pension Benefit Plans or
Olsten  Welfare  Plans,  (ii) no  termination  proceedings  involving the Olsten
Pension Benefit Plans and (iii) no pending or, to Olsten's knowledge, threatened
claims  (other than routine  claims for  benefits),  suits or  proceedings  with
respect to any Olsten Pension  Benefit Plan or Olsten Welfare Plan,  against the
assets of any of the trusts  under any  Olsten  Pension  Benefit  Plan or Olsten
Welfare  Plan or against any  fiduciary  of any Olsten  Pension  Benefit Plan or
Olsten  Welfare Plan with respect to the operation of such plan or asserting any
rights or claims to benefits  under any Olsten  Pension  Benefit Plan or against
the assets of any trust under such plan, nor, to Olsten's  knowledge,  are there
any facts which  would give rise to any such  investigations,  claims,  suits or
proceedings,  except  for any such  matter  which  would  not,  singly or in the
aggregate with all other failures,  non-compliance,  liabilities,  transactions,
events and other matters that are the subject of any representation and warranty
under this  Section  4.14,  reasonably  be expected  to have an Olsten  Material
Adverse Effect.

          (g) None of Olsten,  any of its  Subsidiaries  or any  employee of the
foregoing, nor any trustee,  administrator,  other fiduciary or any other "party
in interest" or "disqualified person" with respect to the Olsten Pension Benefit
Plans or Olsten Welfare  Plans,  has engaged in a "prohibited  transaction"  (as
such term is defined in Section  4975 of the Code or Section 406 of ERISA) which
would be reasonably  likely to result in a tax,  penalty,  or other liability on
Olsten or any of its  Subsidiaries  under  Section  4975 of the Code or  Section
502(i) of  ERISA,  except  any such  event  which  would  not,  singly or in the
aggregate with all other failures,  non-compliance,  liabilities,  transactions,
events and other matters that are the subject of any representation and warranty
under this  Section  4.14,  reasonably  be expected  to have an Olsten  Material

respect to any Olsten Pension  Benefit Plan requiring  disclosure  under Section
4063(a) of ERISA or any event with  respect to any Olsten  Pension  Benefit Plan
requiring disclosure under Section 4041(c)(3)(C) of ERISA.




                                       29
<PAGE>
          (i) Neither Olsten nor any Subsidiary of Olsten nor any of their ERISA
Affiliates has incurred any currently  outstanding liability to the PBGC or to a
trustee  appointed  under  Section  4042(b)  or (c) of ERISA  other than for the
payment of  premiums,  all of which have been paid when due.  No Olsten  Pension
Benefit  Plan has applied  for,  or  received,  a waiver of the minimum  funding
standards  imposed by Section 412 of the Code. The  information  supplied to the
actuary  by  Olsten or any of its  Subsidiaries  for use in  preparing  the most
recent  actuarial  report for the Olsten  Pension  Benefit Plans is complete and
accurate in all material respects.

          (j) Neither  Olsten,  any of its  Subsidiaries  nor any of their ERISA
Affiliates has any material liability  (including any contingent liability under
Section  4204 of ERISA)  with  respect  to any  multiemployer  plan,  within the
meaning of Section 3(37) of ERISA.

          (k) With  respect  to each of the  Olsten  Pension  Benefit  Plans and
Olsten  Welfare  Plans,  true,  correct  and  complete  copies of the  following
documents have been delivered or made available to Adecco: (i) the current plans
and related trust  documents,  including  amendments  thereto,  (ii) any current
summary  plan  descriptions,   (iii)  the  most  recent  Forms  5500,  financial
statements and actuarial  reports,  if applicable,  and (iv) the most recent IRS
determination letter, if applicable,  and (v) any filings with or correspondence
to or from the IRS, or compliance  statements,  with respect to self-corrections
of any disqualifying defects pursuant to Revenue Procedure 98-22.

          (l) Neither Olsten, any of its Subsidiaries, any organization to which
Olsten is a  successor  or parent  corporation,  within  the  meaning of Section
4069(b)  of  ERISA,  nor  any of  their  ERISA  Affiliates  has  engaged  in any
transaction  described  in Section  4069(a) of ERISA which would  reasonably  be
expected to result in a material liability to Olsten or its Subsidiaries.

          (m) None of the Olsten  Welfare  Plans  maintained by Olsten or any of
its  Subsidiaries  are  retiree  life or retiree  health  insurance  plans which
provide  for  continuing  benefits  or  coverage  for  any  participant  or  any
beneficiary of a participant following termination of employment,  except as may
be required under the Consolidated Omnibus Budget Reconciliation Act of 1985, as
amended  ("COBRA"),  or  except  at  the  expense  of  the  participant  or  the
participant's beneficiary.  Olsten and each of its Subsidiaries which maintain a
"group  health plan" within the meaning of Section  5000(b)(1)  of the Code have
complied with the notice and continuation requirements of Section 4980(B) of the
Code,  COBRA,  Part 6 of  Subtitle  B of  Title I of ERISA  and the  regulations
thereunder, except for noncompliance which would not, singly or in the aggregate
with all other failures, non-compliance,  liabilities,  transactions, events and
other matters that are the subject of any representation and warranty under this
Section 4.14, reasonably be expected to have an Olsten Material Adverse Effect.

          (n) No  liability  under any  Olsten  Pension  Benefit  Plan or Olsten
Welfare Plan has been funded nor has any such obligation been satisfied with the
purchase of a contract  from an  insurance  company as to which Olsten or any of
its  Subsidiaries  has  received  notice  that  such  insurance  company  is  in
rehabilitation.

          (o)  The  execution   of,  and   consummation   of  the   transactions
contemplated  by, this Agreement and the Separation  Agreement will not,  either
alone or upon the occurrence of subsequent events,  result in an increase in the
amount of  compensation  or  benefits  or  accelerate  the  vesting or timing of
payment or funding of any benefits or  compensation  payable to or in respect of
any employee or former employee of Olsten or any of its Subsidiaries. Olsten has
disclosed to Adecco in the Olsten Disclosure  Statement any severance agreements
or severance  policies of Olsten or its Subsidiaries  providing  benefits in the

          (p) Olsten has  disclosed  to Adecco in Section  4.14(p) of the Olsten
Disclosure  Statement  each  of  Olsten's  material  Olsten  Foreign  Plans  (as
hereinafter  defined) to the extent the  benefits  provided  thereunder  are not
mandated by the laws of the applicable foreign jurisdiction.  Olsten and each of
its  Subsidiaries  and each of such Olsten Foreign Plans are in compliance  with
applicable  laws and all  required  contributions  have been made to the  Olsten
Foreign Plans,  except where the failure to comply or make  contributions  would
not,  singly  or in the  aggregate  with  all  other  failures,  non-compliance,
liabilities,  transactions, events and other matters that are the subject of any
representation  and warranty under this Section 4.14,  reasonably be expected to
have an Olsten Material Adverse Effect. For purposes of this Agreement, the term
"Olsten Foreign Plan" shall mean any employee benefit plan,  program,  policy or
arrangement  maintained or contributed  to, by, or entered into with,  Olsten or
any of its Subsidiaries with respect to employees (or former employees) employed
outside the United States.

          Section 4.15 Labor and Employment Matters.  (a) Each of Olsten and its
Subsidiaries is in compliance in all material  respects with all applicable laws
respecting  employment  and  employment  practices,   terms  and  conditions  of
employment,  safety,  wages  and  hours,  and  neither  Olsten  nor  any  of its
Subsidiaries  is engaged in any unfair  labor  practice in each case,  except as
would not,  individually or in the aggregate,  reasonably be expected to have an
Olsten Material  Adverse Effect.  Olsten and each of its  Subsidiaries:  (i) has
withheld all amounts  required by law or by agreement to be withheld from wages,
salaries and other  payments to employees;  (ii) to Olsten's  knowledge,  is not
liable  for any  arrears  of wages or any taxes or any  penalty  for  failure to
comply with any of the laws set forth in the  preceding  sentence;  and (iii) is
not  liable  for any  material  payment  to any  trust or  other  fund or to any
Governmental Authority or administrative authority, with respect to unemployment
compensation  benefits,  social  security or other benefits or  obligations  for
employees  (other  than  routine  payments  to be made in the  normal  course of
business  and  consistent  with  past  practice),  except in the case of each of
clauses (i),  (ii) and (iii),  for failures to withhold  and  liabilities  which
would not,  individually or in the aggregate,  have an Olsten  Material  Adverse
Effect.  There  are  no  pending,  or,  to  Olsten's  knowledge,  threatened  or
reasonably anticipated claims or actions against under any worker's compensation
policy or long-term disability policy,  except as would not,  individually or in
the aggregate, have an Olsten Material Adverse Effect. There is no labor strike,
slowdown or stoppage pending (or, to the knowledge of Olsten,  any labor strike,
slowdown  or  stoppage  threatened)  against or  affecting  Olsten or any of its
Subsidiaries,  except as would not,  individually  or in the aggregate,  have an
Olsten Material Adverse Effect. None of Olsten or its Subsidiaries is a party to
any union  contract or  collective  bargaining  agreement in North  America.  To
Olsten's knowledge, no union organizing activities with respect to any of its or
its  Subsidiaries'  employees are occurring or threatened,  except as would not,
individually or in the aggregate, have an Olsten Material Adverse Effect.

<PAGE>
          (b)  Neither  Olsten  nor any of its  Subsidiaries  is a party  to any
employment,  management  services,  consultation  or other contract or agreement
with any past or present  officer or  director  or, to Olsten's  knowledge,  any
entity  affiliated with any past or present officer or director,  other than the
agreements  executed  by  employees  generally,  the  forms of which  have  been
provided to Adecco.

          Section 4.16 No Change of Control Payments.  Neither the execution and
delivery by Olsten of this  Agreement or the execution and delivery by Olsten or
OHS of the Separation  Agreement nor the consummation of any of the transactions
contemplated  hereby or thereby gives rise to any obligation of Olsten or any of
its Subsidiaries to, or any right of any holder of any security (equity or debt)
of Olsten or any of its Subsidiaries or any holder of any other  indebtedness of
Olsten or any of its  Subsidiaries  or any of Olsten's  franchisees  or licensed
area representatives to, require Olsten to purchase, offer to purchase,  redeem,
otherwise  prepay or repay,  pay any penalty or otherwise make any payments with
respect to, any such  security,  indebtedness,  or  franchise  or licensed  area
representative contract or agreement, or deposit any funds to effect the same.

          Section 4.17 Environmental Matters. Except as would not have an Olsten
Material Adverse Effect:

          (a) Olsten and each of its  subsidiaries  are in  compliance  with and
     have no liability under applicable Environmental Laws;

          (b)  there is no  civil,  criminal  or  administrative  action,  suit,
     demand,  claim,  hearing,  notice of  violation,  investigation,  notice or
     demand letter, or request for information pending, or to Olsten's knowledge
     threatened,  under any Environmental  Law (as hereinafter  defined) against
     Olsten or any of its Subsidiaries;

          (c) neither Olsten nor any of its  Subsidiaries  has received  written
     notice of actual or potential  liability under any  Environmental  Law that
     has not been  resolved,  or is  performing  or  obligated  to  perform  any
     investigation or other action under any Environmental Law;

          (d) to  Olsten's  knowledge  after due  inquiry,  there are no past or
     present events, activities,  conditions or occurrences,  including, without
     limitation,  any  disposal,  spill,  discharge or release of any  Hazardous
     Materials (as hereinafter  defined),  that would  reasonably be expected to
     result in any liability under any  Environmental  Law on the part of Olsten
     or any of its subsidiaries; and

          (e) to Olsten's knowledge, there is no asbestos or underground storage
     tank  located at, on or under any facility or property  owned,  operated or
     leased by Olsten or any of its Subsidiaries.

          As used in this  Agreement,  the term  "Environmental  Laws" means the
common  law,  and any  law,  statute,  rule,  regulation,  ordinance,  judgment,
directive,   order  or  decree  relating  to  pollution  or  protection  of  the
environment, including without limitation, natural resources, or to human health
or safety; and the term "Hazardous Materials" means any pollutant,  contaminant,
chemical, substance,  constituent, waste or material regulated or which can give
rise to liability under any Environmental Law.

          Section 4.18  Insurance.  Olsten has  insurance  policies and fidelity
bonds  covering  its  and  its  Subsidiaries'   assets,   business,   equipment,
properties,  operations,  employees,  officers and  directors of the type and in
amounts  customarily  carried by persons conducting  business similar to that of
Olsten  and such  Subsidiaries.  All  premiums  due and  payable  under all such
policies and bonds have been paid,  and Olsten is  otherwise in full  compliance
with the terms and  conditions of all such policies and bonds,  except where the
failure to have made payment or to be in full compliance  would not,  singularly
or in the  aggregate  with all such  other  failures,  have an  Olsten  Material
Adverse Effect. The reserves  established by Olsten in respect of all matters as
to which Olsten self-insures or carries retention and/or deductibles,  including
for  workers'  medical  coverage  and  workers'  compensation,  are adequate and
appropriate in light of Olsten's  experience  with respect thereto and Olsten is
not aware of any facts or  circumstances  existing  as of the date  hereof  that
could  reasonably  be  expected  to cause  such  reserves  to be  inadequate  or
inappropriate.

          Section 4.19 Leases.  Neither Olsten nor any of its Subsidiaries  owns
any real  property.  Olsten has  delivered or made  available to Adecco true and
complete copies of each lease requiring the payment of rentals  aggregating,  or
pursuant  to which the annual  rentals are  reasonably  expected to be, at least
$250,000 per annum pursuant to which real property is held under lease by Olsten
or any of its Subsidiaries,  and true and complete copies of each lease pursuant
to which  Olsten or any of its  Subsidiaries  leases  real  property  to others.
Section 4.19 of the Olsten  Disclosure  Statement sets forth a true and complete
list of all such leases. All of the leases of Olsten or its Subsidiaries  listed
on Section 4.19 of the Olsten Disclosure Statement, are valid and subsisting and
in full force and effect  with  respect to Olsten and its  Subsidiaries,  as the
case may be, and, to Olsten's knowledge, with respect to any other party thereto
except  any such  failures  to be in full  force  and  effect  as  would  not be
reasonably  expected to have an Olsten Material  Adverse Effect.  Neither Olsten
nor any of its  Subsidiaries  nor, to  Olsten's  knowledge,  any  landlord is in
default of its  obligations  under any lease to which  Olsten is bound  and,  to
Olsten's knowledge,  there are no conditions which, given notice and the passage
of time,  could  constitute a default under such lease,  except for any defaults
which  would not  reasonably  be  expected  to have an Olsten  Material  Adverse
Effect.  Olsten or its  Subsidiaries,  as the case may be, have valid  leasehold
interests  in all  properties  leased  thereunder  free and clear of all  liens,
except as would not,  individually or in the aggregate,  have an Olsten Material
Adverse Effect.  To Olsten's  knowledge,  the leased real properties are in good
operating order and condition.

          Section 4.20  Contracts  and  Commitments.  (a) As of the date hereof,
none of Olsten or any of its  Subsidiaries is a party to any existing  contract,
obligation or commitment of any type in any of the following  categories  except
for  contracts  filed as  exhibits  to the  Olsten  SEC  Reports or set forth in
Section 4.20 of the Olsten  Disclosure  Statement  (true and complete  copies of
which contracts have been delivered to or made available to Adecco):

               (i) contracts that provide for annual payments to or by Olsten or
     any of its Subsidiaries aggregating in excess of $6,000,000;








                                       33
<PAGE>
               (ii) any  contract  under which Olsten or any  Subsidiary  has or
     may, except by way of endorsement of negotiable  instruments for collection
     in the  ordinary  course of business  and  consistent  with past  practice,
     become   absolutely  or  contingently  or  otherwise  liable  for  (x)  the
     performance  under a contract of any other person,  firm or  corporation or
     (y) the whole or any part of the  indebtedness  or liabilities of any other
     person,  firm or  corporation,  in all  cases,  individually  in  excess of
     $1,000,000 and in the aggregate in excess of $5,000,000;

               (iii) employment agreements,  consulting agreements, contracts or
     commitments  with any  employee or member of Olsten's  Board of  Directors,
     other than those which are terminable by Olsten or any of its  Subsidiaries
     on not  more  than  thirty  days  notice  without  liability  or  financial
     obligation,  and within each such  category  of  agreements,  contracts  or
     commitments, which are individually in excess of $150,000;

               (iv) any agreements or plans, including,  without limitation, any
     stock  option,   stock  appreciation  right  or  stock  purchase  plans  or
     agreements,  any of the benefits of which will be increased, or the vesting
     of benefits of which will be  accelerated,  by the occurrence of any of the
     transactions  contemplated  by this  Agreement  or the  value of any of the
     benefits  of  which  will  be  calculated  on  the  basis  of  any  of  the
     transactions contemplated by this Agreement;

               (v) any  contract  with any  director,  officer  or more  than 5%
     stockholder of Olsten other than in such person's capacity as a director or
     officer of Olsten or any  contract  with any entity in which,  to  Olsten's
     knowledge, any director,  officer or more than 5% stockholder or any family
     member of any  director,  officer or  stockholder  has a material  economic
     interest;

               (vi) any  contract  that  limits  or  restricts  in any  material
     respect  where Olsten or any of its  Subsidiaries  may conduct its or their
     business  or the  type  or  line  of  business  that  Olsten  or any of its
     Subsidiaries may engage in; and

               (vii) any material contract containing any agreement with respect
     to any change of control.

          (b)  All of  the  contracts  listed  in  Section  4.20  of the  Olsten
Disclosure  Statement are in full force and effect,  except for those  contracts
the  ineffectiveness of which would not reasonably be expected to have an Olsten
Material  Adverse Effect.  None of Olsten or its Subsidiaries is in breach of or
default  under any  contract  to which it is a party,  except  for  breaches  or
defaults  that  would  not,  individually  or in the  aggregate,  either  impair
Olsten's  or OHS' (as  applicable)  ability  to  consummate  the  Merger  or the
Split-Off or the other  transactions  contemplated  hereby or by the  Separation
Agreement or have an Olsten Material Adverse Effect.

          Section  4.21 Finders or Brokers.  Other than Warburg  Dillon Read and
Salomon Smith Barney,  neither Olsten nor any of its  Subsidiaries  has employed
any investment  banker,  broker,  finder or  intermediary in connection with the
transactions  contemplated  hereby  who  might  be  entitled  to a  fee  or  any
commission the receipt of which is conditioned  upon  consummation of the Merger
or the amount of which is calculated  with  reference to any part of the Closing
Consideration.

          Section 4.22  Opinions.  The Board of Directors of Olsten has received
the  opinions of Warburg  Dillon Read LLC and Salomon  Smith  Barney Inc. to the
effect that as of the date of this Agreement the Closing  Consideration  is fair
to the holders of Olsten Common Stock from a financial point of view.

          Section  4.23 Board  Recommendation.  The Board of Directors of Olsten
has,  by a  unanimous  vote at a meeting  of such  board duly held on August 14,
1999,  approved and adopted this  Agreement,  the Merger,  the Split-Off and the
other  transactions  contemplated  hereby and thereby,  and determined that this
Agreement,  the Separation  Agreement,  the Merger,  the Split-Off and the other
transactions  contemplated hereby and thereby,  taken together,  are in the best
interest of the stockholders of Olsten, and prior to the date hereof resolved to
recommend  that the  holders  of Olsten  Common  Stock  approve  and adopt  this
Agreement, the Merger and the other transactions contemplated hereby.

          Section  4.24 Voting  Requirements.  The approval by a majority of the
voting power  represented by the  outstanding  shares of Olsten Stock and Olsten
Class B Stock entitled to vote thereon,  and voting  together as a single class,
is the only vote of the holders of any class of Olsten's capital stock necessary
to approve this Agreement,  the Merger and the other  transactions  contemplated
hereby.  No  separate  approval  by the  holders of any other class or series of
capital  stock of Olsten is necessary to approve this  Agreement,  the Merger or
any of the other transactions contemplated hereby.

          Section  4.25 State  Antitakeover  Statutes.  Olsten has  granted  all
approvals  and taken all other steps  necessary  to exempt this  Agreement,  the
Voting Agreement, the Merger and the other transactions contemplated hereby from
the requirements and provisions of Section 203 of the Delaware Act and any other
state or other antitakeover  statute or regulation to the extent applicable such
that  none of the  provisions  of  such  "business  combination,"  "moratorium,"
"control share," or other state antitakeover statute or regulation (x) prohibits
or restricts Olsten's ability to perform its obligations under this Agreement or
its ability to  consummate  the Merger and the other  transactions  contemplated
hereby,  (y) would have the effect of  invalidating or voiding this Agreement or
any  provisions  hereof,  or (z) would subject  Olsten or Adecco to any material
impediment  or  condition  in  connection  with  the  exercise  of any of  their
respective rights under this Agreement.

                                   ARTICLE V.

                                    COVENANTS

          Section 5.01  Conduct of Business of Olsten and Adecco.  (a) Except as
specifically  contemplated  by this Agreement or the Separation  Agreement or as
expressly  agreed to in writing by  Adecco,  during the period  from the date of
this Agreement to the Effective Time, each of Olsten and its  Subsidiaries  will
conduct its  operations  according  to its ordinary and usual course of business
consistent with past practice, and will use all commercially  reasonable efforts
to preserve intact its business organization,  to keep available the services of
its officers  and  employees  and to maintain  satisfactory  relationships  with
suppliers,  vendors,  contractors,   customers  and  others  having  significant
business  relationships  with it and will take no action  that  would  adversely
affect  its  ability  to  consummate  the  Merger,  the  Split-Off  or the other
transactions  contemplated  hereby  or  by  the  Separation  Agreement.  Without





                                       35
<PAGE>
limiting the  generality  of the  foregoing,  and except as otherwise  expressly

(collectively  "Agents")  to,  directly or  indirectly,  (w) solicit,  initiate,

information)  any  inquiries  or the  making  of any  offer or  proposal  by any

Party")  with respect to, or that could  reasonably  be expected to lead to, any
merger, consolidation,  share exchange, business combination, tender or exchange
offer or other similar  transaction  regarding Olsten or any of its Subsidiaries
or  involving  the  acquisition  of a  substantial  portion (15% or more) of the
assets of Olsten and any of its Subsidiaries, taken as a whole, or a significant

provided,  however,  that Olsten may,  in  response to a Superior  Proposal  (as

not otherwise  result from a breach of this Section 5.02,  subject to compliance

                                       39
<PAGE>
engage in discussions  and  negotiations  with, such Third Party, if but only if
(A) the Board of Directors of Olsten,  having received (x) the advice of outside
legal  counsel  that  failure  to take  such  action  would be a  breach  of its
fiduciary duties to its stockholders  under applicable law and (y) the advice of
a financial  advisor of nationally  recognized  reputation that the party making
such proposal is  financially  capable and that such Superior  Proposal would be
more  favorable  from a  financial  point of view to its  stockholders  than the
Merger and the Split-Off,  reasonably  determines in good faith that taking such
action is reasonably  likely to lead to an Acquisition  Transaction that is more
favorable to it and its stockholders  than the Merger and the Split-Off and that
failing to take such action would be a breach of the directors' fiduciary duties
under  applicable  law, (B) prior to  furnishing or  disclosing  any  non-public
information to, or entering into  discussions or  negotiations  with, such Third
Party, it receives from such Third Party an executed  confidentiality  agreement
with respect to the  information to be furnished with terms no less favorable in
the aggregate to it than those contained in the Confidentiality  Agreement,  but
which  confidentiality  agreement  shall not (nor shall any other  agreement  or
arrangement between Olsten or any of its Subsidiaries, on the one hand, and such
Third Party, on the other hand, or any of their  respective  Agents) provide for
any exclusive  right to negotiate  with Olsten or any payments by Olsten and (C)
it advises  Adecco of all such  non-public  information  delivered to such Third
Party no later than  concurrently  with such  delivery.  Nothing in this Section
5.02 shall  prohibit the Board of Directors of Olsten from  complying  with Rule
14e-2  promulgated  under the  Exchange  Act with regard to a tender or exchange
offer.  As used  herein,  "Superior  Proposal"  means a bona fide,  written  and
unsolicited offer made by a financially  responsible Third Party with respect to
an Acquisition  Transaction  involving the acquisition of all of Olsten's equity
interests  (or  all or  substantially  all of  Olsten's  and  its  Subsidiaries'
assets).  Without limiting the foregoing, it is understood that any violation of
the restrictions set forth in this Section 5.02(a) by any officer or director of
Olsten or any of its  Subsidiaries or any investment  banker,  attorney or other
advisor  or Agent of Olsten or any of its  Subsidiaries  shall be deemed to be a
breach of this Section 5.02 by Olsten.

          (b) Olsten shall (i) as promptly as  practicable  (and in any event no
later than the close of business  on the next  business  day)  notify  Adecco in
writing of receipt of any  inquiries,  proposals  or offers  with  respect to an
Acquisition  Transaction or any request for nonpublic information relating to it
in connection with an Acquisition Transaction or for access to its or any of its
Subsidiaries'  properties,  books or  records by any Third  Party  that  informs
Olsten's Board of Directors that it is considering making, or has made (or which
Olsten's Board of Directors reasonably believes may be considering making or has
made) a proposal or offer with respect to an  Acquisition  Transaction,  (ii) in
such written  notice,  indicate in reasonable  detail the identity of such Third
Party  (including  the name of such Third Party) and the terms and conditions of
such proposal or offer,  (iii)  immediately cease and cause to be terminated any
existing  activities,  discussions or  negotiations  with any parties  conducted
heretofore with respect to any of the foregoing, and take all necessary steps to
inform  such  individuals  or  entities of the  obligations  undertaken  in this
Section 5.02 and (iv) as promptly as practicable (and in any event no later than
the close of business on the next  business day) notify Adecco in writing of any
determination  by its Board of  Directors  to furnish  information  or engage in
discussions  or  negotiations  with any Third  Party.  If any notice is given or
required to be given in accordance with clause (iv) of the immediately preceding





                                       40
<PAGE>
sentence,  then Olsten shall thereafter  continue to keep Adecco informed,  on a
current basis,  of the status of any such  discussions or  negotiations  and the
terms being discussed or negotiated. Notwithstanding the foregoing, Olsten shall
not accept or enter into any  agreement  concerning  a Superior  Proposal  for a
period  of  at  least  three  business  days  after  Adecco's   receipt  of  the
notification of the terms thereof pursuant to the second preceding sentence (and
only in  compliance  with the terms of Article X hereof),  during  which  period
Adecco  shall be  afforded  the  opportunity  to match the terms and  conditions
contained  in such  Superior  Proposal  (with  equivalent  value  in the case of
non-cash consideration).

          Section  5.03 Access to  Information.  (a) Subject to the terms of the
Confidentiality   Agreement,   dated  April  15,   1999  (the   "Confidentiality
Agreement"), between Olsten and Adecco, from the date hereof until the Effective
Time,  Olsten will give  Adecco and its  authorized  representatives  (including
counsel, consultants, accountants, auditors and agents) reasonable access during
normal  business hours to all facilities and to all books and records (and audit
workpapers of independent  public  accountants) of it and its  Subsidiaries  and
will cause its officers  and those of its  Subsidiaries  to furnish  Adecco with
such reasonable  financial and operating data and other information with respect
to its  business  and  properties  as Adecco  may from  time to time  reasonably
request,  in each  case,  in a manner  that does not unduly  interfere  with the
normal operations of Olsten's business.

          (b)  Subject to the terms of the  Confidentiality  Agreement  from the
date hereof until the Effective Time, Adecco will give Olsten and its authorized
representatives  (including  counsel,  consultants,  accountants,  auditors  and
agents) reasonable access during normal business hours to such facilities and to
its officers and  representatives  and provide such  information with respect to
its business and properties as Olsten may from time to time  reasonably  request
as is customarily  provided by a Swiss corporation to its stockholders and which
is materially  necessary in order for Olsten to determine the value of the Stock
Consideration  to be issued in the Merger,  in each case,  in a manner that does
not unduly interfere with the normal operations of Adecco's business;  provided,
however, to the extent the exercise of fiduciary duty, in the opinion of outside
legal counsel,  may require access to additional documents in order to determine
such value,  Adecco will use all reasonable  efforts to provide Olsten with such
documents.

          Section 5.04 Registration Statements and Proxy Statements. (a) As soon
as is reasonably  practicable  after the date hereof (i) Olsten,  in cooperation
with Adecco, will prepare the Olsten Proxy Statement,  (ii) Olsten and OHS shall
prepare  a  Registration  Statement  on  Form  S-4 (or any  successor  form)  in
connection with the  registration  under the Securities Act of the shares of OHS
Common Stock to be issued at the Effective Time as Split-Off  Consideration (the
"OHS  Registration  Statement"),  (iii)  Adecco will  prepare  the Adecco  Proxy
Statement, (iv) Adecco will prepare a Registration Statement on Form F-4 (or any
successor  form)  (the  "Adecco  Registration  Statement")  and will  cause  the
Depositary  to prepare a  Registration  Statement on Form F-6 (or any  successor
form)  (the  "Depositary  Registration  Statement,"  and  together  with the OHS
Registration Statement and the Adecco Registration Statement,  the "Registration
Statements"),  in each  case in  connection  with  the  registration  under  the
Securities  Act of the shares of Adecco Common Stock and Adecco ADSs  (evidenced
by  Adecco  ADRs) to be  issued at the  Effective  Time as Stock  Consideration.





                                       41
<PAGE>
Olsten shall,  with the  cooperation of Adecco,  file the Olsten Proxy Statement
with the SEC and shall cause OHS to timely file the OHS  Registration  Statement
with the SEC and Adecco shall,  with the cooperation of Olsten,  timely file the
Adecco Registration  Statement with the SEC. The parties will cooperate to cause
the  Olsten  Proxy  Statement,  the OHS  Registration  Statement  and the Adecco
Registration  Statement  (collectively,  the "Filed  Documents") to comply as to
form in all material  respects with the applicable  provisions of the Securities
Act and the Exchange  Act. The parties will  cooperate to cause the Adecco Proxy
Statement to comply with any applicable laws or regulations,  including those of
any foreign or national  securities  exchange on which  Adecco  Common  Stock or
Adecco ADSs are listed.  Olsten and Adecco shall, and Olsten shall cause OHS to,
use their respective  reasonable best efforts to have the Olsten Proxy Statement
cleared  by the  SEC,  to have the OHS  Registration  Statement  and the  Adecco
Registration  Statement declared effective by the SEC as promptly as practicable
after the filing  thereof  (including,  without  limitation,  responding  to any
comments  received  from  the SEC  with  respect  thereto)  and to keep  the OHS
Registration  Statement and the Adecco Registration  Statement effective as long
as is necessary to consummate the Split-Off and the Merger, as applicable.  Each
party shall,  and Olsten will cause OHS to, as promptly as practicable,  provide
the other party with copies of any written  comments  received from the SEC with
respect to the Filed  Documents  and advise the other of any oral  comments with
respect  thereto  received  from the SEC.  Olsten  and  Adecco  shall  use their
respective reasonable best efforts to obtain, prior to the effective date of the
OHS  Registration  Statement,  all necessary  state  securities  law or Blue Sky
permits or approvals required to carry out the transactions contemplated by this
Agreement and the Separation Agreement. Olsten or OHS will pay all such expenses
required  for the OHS  Registration  Statement  and  Adecco  will  pay all  such
expenses required by the Adecco Registration Statement.

          (b) Each party agrees that none of the  information  supplied or to be
supplied by it or its  Subsidiaries  for inclusion or incorporation by reference
in the Filed  Documents  (i) in the case of the Olsten Proxy  Statement and each
amendment or supplement  thereto, at the time of mailing thereof and at the time
of the stockholders  meetings  contemplated by Section 1.05, or (ii) in the case
of the OHS Registration  Statement or the Adecco Registration Statement and each
amendment or supplement  thereto,  at the time it is filed or becomes  effective
and thereafter  until the Effective Time, will contain an untrue  statement of a
material fact or omit to state a material fact required to be stated  therein or
necessary to make the statements  therein,  in light of the circumstances  under
which they were made, not misleading. If at any time prior to the Effective Time
an  event  with  respect  to  Olsten  or  its  Subsidiaries  or  Adecco  or  its
Subsidiaries shall occur that is required to be described in the Filed Documents
or the Adecco Proxy Statement such event shall be so described, and an amendment
or  supplement  shall be  promptly  filed with the SEC (in the case of the Filed
Documents) and, as required by law,  disseminated to the stockholders of Olsten.
No amendment or supplement  to any Filed  Document will be made by either party,
and Olsten  will not  permit  any  amendment  or  supplement  to be made by OHS,
without the  approval of both Olsten and Adecco,  except,  in each case,  to the
extent such party is advised by outside legal counsel that any such amendment or
supplement is required by law, in which case it shall be permitted to the extent
so  required.  Each of Olsten and Adecco will advise the other  party,  promptly
after  it  receives  notice  thereof,  of the  time  when  the OHS  Registration
Statement  or the Adecco  Registration  Statement  has become  effective  or any
supplement or amendment has been filed,  the issuance of any stop order,  or the





                                       42
<PAGE>
suspension of the qualification of the OHS Common Stock, the Adecco Common Stock
or Adecco ADRs issuable in connection  with the Transaction for offering or sale
in any  jurisdiction or any request by the SEC for amendment of any of the Filed
Documents or comments  thereon and responses  thereto or requests by the SEC for
additional information.

          Section 5.05 Other Actions;  Filings;  Consents.  Subject to the terms
and conditions provided in this Agreement and the Separation  Agreement,  Olsten
and Adecco shall (i) use their  reasonable  best efforts to take, or cause to be
taken,  all  other  actions  and do,  or  cause  to be done,  all  other  things
necessary,  proper or  appropriate  under  applicable  laws and  regulations  or
required  to be taken  by any  Governmental  Authority  to  consummate  and make
effective the  transactions  contemplated  by this  Agreement and the Separation
Agreement as promptly as practicable,  (ii) use their reasonable best efforts to
make, as promptly as practicable, all necessary filings, and thereafter make any
other  required  submissions  with  respect to this  Agreement,  the  Separation
Agreement,  the Merger or the Split-Off  required under (A) the Securities  Act,
the Exchange Act and any other applicable  foreign,  federal or state securities
laws or  regulations,  (B) the HSR Act and any applicable  foreign  antitrust or
similar laws and any related  governmental  request thereunder and (C) any other
applicable  federal,  state, local or foreign statute,  law, rule or regulation,
(iii)  use  their  reasonable  best  efforts  to  obtain  from any  Governmental
Authorities any consents, licenses, permits, waivers, approvals,  authorizations
or orders  required  to be  obtained or made by Olsten or Adecco or any of their
respective  Subsidiaries  in connection  with the  authorization,  execution and
delivery of this Agreement, the Separation Agreement and the consummation of the
transactions  contemplated  hereby and thereby,  (iv) use their  reasonable best
efforts  to  resolve  any  objections  as may be  asserted  by any  Governmental
Authority  with  respect to the Merger and the  Split-Off  and the  transactions
contemplated hereby and in the Separation Agreement under any antitrust or trade
or regulatory laws or regulations of any Governmental Authority, (v) furnish the
other with copies of all correspondence, filings and communications between them
and their affiliates and their respective representatives,  on the one hand, and
any Governmental  Authority or member of their respective  staffs,  on the other
hand,  with  respect to this  Agreement  and the  Separation  Agreement  and the
transactions  contemplated hereby and thereby,  (vi) furnish the other with such
necessary  information  and  reasonable  assistance as the other may  reasonably
request in connection with their preparation of necessary filings, registrations
or submissions of information to any Governmental  Authority and (vii) use their
reasonable best efforts to defend  vigorously any litigation  seeking to enjoin,
prevent  or  delay  the  consummation  of the  Merger  or the  Split-Off  or the
transactions  contemplated  hereby or in the  Separation  Agreement  or  seeking
material  changes and to lift,  remove or rescind any  injunction or restraining
order  or  other  order  adversely  affecting  the  ability  of the  parties  to
consummate the transactions contemplated hereby.

          Section 5.06 Public Announcements. Before issuing any press release or
otherwise making any public statement with respect to the Merger, the Split-Off,
any  Acquisition  Transaction or any of the other  transactions  contemplated by
this Agreement or the Separation Agreement, Olsten and Adecco will consult with,
and obtain the consent of, each other as to its form and substance and shall not
issue  any  such  press  release  or make  any such  public  statement  prior to
obtaining  such  consent,  except as may be  required  by law or pursuant to any
order of any court or governmental agency, tribunal or regulatory authority.

one or more of its  representatives  to confer on a regular and  frequent  basis
with  representatives  of the other and to report on the  general  status of its
ongoing operations.  Each party shall give prompt notice to the other parties of
(i) any written notice or other communication from any Third Party alleging that
the consent of such Third Party is or may be  required  in  connection  with the
Merger or Split-Off or other transactions  contemplated by this Agreement or the
Separation  Agreement,  (ii) its receipt of written  notice of any  governmental
complaints,  investigations or hearings or any litigation, in each case, that in
its good faith  judgement is (or would be with the passage of time or otherwise)
likely to impair its ability to consummate the transactions contemplated by this
Agreement  or the  Separation  Agreement or to have an Olsten  Material  Adverse
Effect or an  Adecco  Material  Adverse  Effect,  as the case may be,  (iii) any
change or event that in its good faith judgment is (or would be with the passage
of  time  or  otherwise)   likely  to  impair  its  ability  to  consummate  the
transactions  contemplated  by this Agreement or the Separation  Agreement or to
have an Olsten Material Adverse Effect or Adecco Material Adverse Effect, as the
case may be, or (iv) the  occurrence  or existence  of any event that would,  or
could with the passage of time or otherwise, make any representation or warranty
contained herein untrue.

          Section 5.08 Expenses.  Except as set forth in Section 10.04 (or, with
respect to Olsten,  as may be allocated between Olsten and OHS in the Separation
Agreement),  Olsten and Adecco shall bear their respective  expenses incurred in
connection  with this  Agreement,  the  Separation  Agreement,  the Merger,  the

Olsten,  for purposes of Rule 145 under the Securities Act  ("Affiliates"),  and

          Section 5.11  Indemnification.  (a) From and after the Effective Time,
each of Adecco and the Surviving  Corporation shall fulfill and honor all rights
to indemnification now existing in favor of any employee, director or officer of
Olsten  and its  Subsidiaries  as  provided  in its  charter or  by-laws,  in an
agreement  between  any such  person and Olsten or one of its  Subsidiaries,  or
otherwise by law, which  obligation  shall survive the Merger and shall continue
in full  force and  effect  for a period  of not less  than six  years  from the
Effective  Time;  provided that in the event any claim or claims are asserted or
made within such six-year period,  all rights to  indemnification  in respect of
any such claim or claims shall continue  until final  disposition of any and all
such  claims.  Adecco will cause the  Surviving  Corporation  to  indemnify  all
directors  and officers of Olsten (the  "Indemnified  Parties"),  to the fullest
extent that Olsten would have been permitted  under Delaware law and its charter
or bylaws in effect as of the date hereof to indemnify  such  individuals,  with
respect to all matters arising out of or pertaining to such Indemnified  Party's
services as directors or officers of Olsten or any of its Subsidiaries occurring
prior to the Effective  Time,  including  without  limitation  the  transactions
contemplated by this Agreement,  and shall also cause the Surviving  Corporation
to advance  expenses as incurred to the fullest  extent  permitted by applicable
law,  provided the Indemnified  Party to whom expenses are advanced  provides an
undertaking  to repay such  advances if it is  ultimately  determined  that such
Indemnified Party is not entitled to  indemnification.  Adecco and the Surviving
Corporation shall pay reasonable  expenses,  including attorneys' fees, that may
be incurred by any  Indemnifying  Party in  enforcing  the  indemnity  and other
obligations provided for in this Section 5.11. (b)......Adecco agrees that, from
and after the Effective  Time, it shall cause to be maintained in effect for not
less  than  six  years  from the  Effective  Time the  current  policies  of the
directors' and officers' liability insurance maintained by Olsten; provided that
Adecco may substitute therefor policies of at least the same coverage containing
terms  and  conditions  which  are no  less  advantageous,  provided  that  such
substitution  shall not result in any gaps or lapses in coverage with respect to
matters  occurring  prior to the Effective  Time;  and provided,  further,  that
Adecco  shall not be required to pay an annual  premium in excess of 300% of the
last  annual  premium  paid by Olsten  prior to the date hereof and if Adecco is
unable to obtain the insurance  required by this Section 5.11 it shall obtain as
much  comparable  insurance  as  possible  for an annual  premium  equal to such
maximum amount.

          Section 5.12 Settlement Releases. Olsten shall use its reasonable best
efforts to obtain the release of it and each of its affiliates  after the Merger
as  a  party,  guarantor  or  other  obligor  under  and  with  respect  to  the
Governmental Settlement Agreements.

          Section 5.13 Board Representation.  At or prior to the Effective Time,

local  taxes  purposes  as an  integral  part of the Merger and thus  report the
Split-Off  as a  redemption,  for purposes of Section  302(a) of the Code,  of a
number of shares of Olsten  Common  Stock equal in value to the value of the OHS
Common Stock distributed in the Split-Off.

          Section 5.15 Certain Employee  Benefits.  As soon as practicable after
the  execution  of this  Agreement,  Olsten  and  Adecco  shall  confer and work
together in good faith to agree upon mutually  acceptable  employee  benefit and
compensation  arrangements  (and terminate  Olsten Pension  Benefit Plans and/or
Olsten Welfare Plans  immediately prior to the Effective Time if appropriate) so
as to  provide  benefits  and  compensation  to  Olsten  employees  who  will be
employees of the Retained  Businesses  generally  equivalent in the aggregate to
those provided to similarly situated employees of Adecco.

          Section 5.16 Carryback Elections.  Prior to the effective time neither
Olsten  nor any  member of the  affiliated  group of which  Olsten is the common
parent shall make or file any election  with any federal,  state or local agency
or authority which, for purposes of any income or franchise Tax,  prevents or in
any other way impairs Olsten from carrying back existing net operating losses to
prior taxable years.

          Section  5.17 Tax Basis and  Earnings  &  Profits  Study.  Immediately
following the execution of this  Agreement,  Olsten and all of its  Subsidiaries
will  cooperate  fully with  Olsten's  independent  public  accountants  and its
designated  representatives  in  preparing a study of the basis and earnings and
profits for federal  income tax purposes of Olsten and OHS,  which study will be
promptly  furnished to Adecco and its designated  representatives  together with
all background and other materials as shall be reasonably  requested in order to
permit them to review and analyze such study.  Each of the parties hereto shall,
and Olsten  shall  cause OHS to,  attempt  in good  faith to resolve  any issues
raised by Adecco or its designated representatives with respect to such study.

          Section  5.18 Waiver of  Repurchase  Obligation.  Olsten shall use its
reasonable  best  efforts  to cause the Board of  Directors  of  Quantum  Health
Resources to approve the  transactions  contemplated  hereby so as to cause such
transactions  not  to  be  a  Risk  Event  (as  defined  in  the  indenture,  as
supplemented, governing the Quantum Debt).

          Section  5.19 Review and Filing of Tax  Returns.  With  respect to all
consolidated  or combined  federal,  state,  or local  income or  franchise  Tax
Returns  filed on or after  the date  hereof  and prior to the  Effective  Time,
Adecco  shall  have the right to  receive a draft of each  such Tax  Return  for
review reasonably in advance of the due date for filing such Tax Return.  Olsten
shall be obligated to consider in good faith any reasonable  suggestions made by
Adecco with respect to such Tax Returns.  Olsten shall prepare and file all such
Tax Returns in a manner reasonably consistent with past practices.

                                  ARTICLE VI.

                          CONDITIONS TO THE OBLIGATIONS

                           TERMINATION AND ABANDONMENT

          Section 10.01  Termination.  This  Agreement may be terminated and the
Merger may be abandoned any time prior to the Effective Time,  whether before or

    (a)   by mutual  written  consent of the Boards of  Directors  of Olsten and

    (b)   by either  Olsten  or Adecco  if,  without  fault of such  terminating
party,  the Merger shall not have been  consummated on or before March 31, 2000,
which date may be extended by mutual  consent of the parties  hereto;  provided,
however,  that the right to terminate  this  Agreement  pursuant to this Section





                                       49
<PAGE>
10.01(b) shall not be available to any party whose failure to perform or observe
in any  material  respect any of its  obligations  under this  Agreement  in any
manner  shall have been the cause of, or resulted  in, the failure of the Merger
to occur on or before such date;  and provided,  further,  that if, on March 31,
2000,  the Merger could be consummated  but for the failure to obtain  consents,
waivers,  approvals,  authorizations  or  orders  of a  Governmental  Entity  as
contemplated  by Section  6.04,  either Olsten or Adecco may, upon notice to the
other,  extend the period for  consummation  of the Merger to the earlier of the
date on which such  approvals are obtained or June 30, 2000, but only so long as
the party  requesting  such extension shall be using its reasonable best efforts
to obtain  receipt  of such  consents,  waivers,  approvals,  authorizations  or
orders;

    (c)   by either Olsten or Adecco if any court of competent  jurisdiction  or
other Governmental  Authority shall have issued an order (other than a temporary
restraining  order),  decree or ruling  or taken any other  action  restraining,
enjoining or otherwise prohibiting the Merger or the Split-Off,  and such order,
decree, ruling or other action shall have become final and nonappealable;

    (d)   by Olsten,  if the stockholders of Adecco shall have failed to approve
the Adecco Stockholder Proposals at a meeting duly convened therefor;

    (e)   by Adecco,  if the holders of Olsten Common Stock,  voting as a single
class, shall have failed to approve and adopt this Agreement, the Merger and the
other transactions contemplated hereby at a meeting duly convened therefor;

    (f)   by  Olsten,  if Adecco  or  Merger  Sub has  materially  breached  any
representation,  warranty,  covenant or agreement  contained  herein and has not
cured such breach  within ten (10)  business  days of receipt of written  notice
from Olsten or by the Closing Date, if earlier;

    (g)   by  Adecco,  if Olsten has  materially  breached  any  representation,
warranty,  covenant or agreement contained herein or in the Separation Agreement
and has not cured  such  breach  within  ten (10)  business  days of  receipt of
written notice from Adecco or by the Closing Date, if earlier;

    (h)   by  Adecco,  if the  Board  of  Directors  of  Olsten  shall  have (1)
withdrawn,  changed  or  modified  in any  manner  its  recommendation  that its
stockholders  vote  in  favor  of  this  Agreement,  the  Merger  or  the  other
transactions contemplated hereby; (2) Olsten shall have failed to include in the
Olsten Proxy Statement the recommendation of the Board of Directors of Olsten in
favor of the approval of this Agreement,  the Merger and the other  transactions
contemplated  hereby;  (3) the Board of  Directors  of  Olsten or any  committee
thereof shall have approved or publicly recommended any Acquisition Transaction;
(4) Olsten shall have  entered into any letter of intent or similar  document or
any  agreement,  contract or commitment  accepting or expressing an intention to
accept any Acquisition  Transaction;  or (5) a tender or exchange offer relating
to securities of Olsten shall have been commenced by a Person  unaffiliated with
Adecco,  and Olsten  shall not have sent to its  stockholders  pursuant  to Rule
14e-2  promulgated  under the Securities Act, within 10 business days after such
tender  or  exchange  offer  is  first  published  sent or  given,  a  statement
disclosing that Olsten recommends rejection of such tender or exchange offer.

    (i)   by Olsten, prior to the approval by its stockholders of the Merger, if
(1) Olsten shall have received a Superior Proposal which was not solicited by it
after  July 26,  1999 and which did not  result  from a breach of  Section  5.02



                                       50
<PAGE>
hereof,  (2) the Board of Directors of Olsten shall have received (x) the advice
of outside  legal  counsel  that  failure to take the actions  permitted  by the
proviso  to the  first  sentence  of  Section  5.02(a)  would be a breach of the
fiduciary duties of the Board of Directors of Olsten to its  stockholders  under
applicable  law  and  (y)  the  advice  of a  financial  advisor  of  nationally
recognized reputation that the party making such proposal is financially capable
and that such Superior  Proposal would be more favorable from a financial  point
of view to its stockholders than the Merger and the Split-Off,  and, thereafter,
reasonably  determines in good faith that such Superior  Proposal  would be more
favorable  to its  stockholders  than the Merger  and that  failing to take such
actions would be a breach of the directors'  fiduciary  duties under  applicable
law and (3) Olsten shall have given Adecco three  business  days' written notice
prior to such termination and otherwise  complied with the provisions of Section
5.02 and Adecco shall not have matched such  Superior  Proposal;  provided  that
such termination shall not be effective until the fee specified in Section 10.04
has been paid.

          Section 10.02 Procedure for  Termination.  In the event of termination
and  abandonment  of the Merger by any party pursuant to this Article X, written
notice thereof shall immediately be given to the other party.

          Section 10.03 Effect of Termination and  Abandonment.  In the event of
termination of this Agreement and  abandonment of the Merger pursuant to Section
10.01, this Agreement and the Separation Agreement shall become void and have no
effect,  without  liability  on the part of any party (or any of its  directors,
officers or stockholders),  except under this Section 10.03, Sections 5.06, 5.08
and 10.04, Article XII and the Confidentiality  Agreement.  Nothing herein shall
relieve  any party from  liability  for any breach of this  Agreement  occurring
before such termination or shall prejudice the ability of a non-breaching  party
from  seeking  damages  from any other  party for any breach of this  Agreement,
including,  without  limitation,  reasonable  attorneys'  fees and the  right to
pursue any remedy at law or in equity.

          Section 10.04  Termination  Fees. In order for Olsten to induce Adecco
to enter into this Agreement and to reimburse  Adecco for its costs and expenses
related to entering into this Agreement and seeking to consummate the Merger, if
(a) Olsten terminates this Agreement pursuant to 10.01(i); (b) Olsten terminates
this  Agreement  pursuant to Section  10.01 hereof and at such time Adecco would
have been permitted to terminate this Agreement under Section  10.01(h)  hereof;
(c) Adecco  terminates this Agreement  pursuant to Section 10.01(h) hereof;  (d)
Adecco or Olsten  terminates this Agreement  pursuant to Section 10.01(b) or (c)
and (x) at the time of such termination a definitive proposal for an Acquisition
Transaction  has been  provided to Olsten by a Third Party and such proposal has
not been rejected by the Board of Directors of Olsten and (y) within one year of
such  termination  Olsten  shall  have  consummated,  or  have  entered  into  a
definitive agreement with respect to, an Acquisition  Transaction (on terms more
favorable  than the terms of this  Agreement  (without  taking into  account the
payment  of the  fee  provided  for  in  this  Section  10.04));  or (e)  Adecco
terminates  this  Agreement  pursuant to Section  10.01(e) or (g) and within one
year of such termination  Olsten shall have consummated,  or have entered into a
definitive  agreement with respect to, an Acquisition  Transaction on terms more
favorable  than the terms of this  Agreement  (without  taking into  account the
payment of the fee provided for in this Section 10.04), then Olsten shall pay to
Adecco,  concurrently  (i) in the case of  clauses  (a),  (b) and (c) with  such
termination  and (ii) in the case of clauses  (d) and (e),  with the  earlier of
such consummation or entering into of a definitive agreement, a fee, in cash, of
$40,000,000 (the "Termination Fee").

this  Agreement  may be  amended,  modified  or  supplemented  only  by  written
agreement  of Olsten,  Adecco and Merger Sub at any time prior to the  Effective

          Section 12.05 Assignment;  Third Party  Beneficiaries.  This Agreement
and all of the provisions  hereof shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and permitted assigns, but
neither this Agreement nor any of the rights, interests or obligations hereunder
shall be assigned by any of the parties hereto without the prior written consent
of the other parties;  provided,  however, that Adecco shall have the authority,
in its sole discretion,  to assign and transfer the rights, benefits, duties and
obligations of Merger Sub under this Agreement to another newly formed direct or
indirect  Subsidiary  of Adecco.  This  Agreement  is not intended to confer any
rights  or  remedies  hereunder  upon any  other  person  except  for  officers,
directors, or employees of Olsten pursuant to Section 5.11.

          Section 12.06  Governing Law. This Agreement  shall be governed by the
laws of the  State of  Delaware  (regardless  of the laws that  might  otherwise
govern  under  applicable  Delaware  principles  of  conflicts of law) as to all
matters, including but not limited to matters of validity, construction, effect,
performance   and  remedies.   Each  of  the  parties  hereto   irrevocably  and
unconditionally  consents to submit to the exclusive  jurisdiction of the courts
of the State of  Delaware  and of the United  States of  America  located in the
State of Delaware (the "Delaware  Courts") for any litigation  arising out of or
relating to this Agreement and the transactions  contemplated hereby (and agrees
not to commence any litigation  relating thereto except in such courts),  waives
any  objection  to the laying of venue of any such  litigation  in the  Delaware
Courts  and  agrees  not to  plead  or claim in any  Delaware  Court  that  such
litigation  brought therein has been brought in an inconvenient  forum.  Each of
the parties hereto hereby agrees to service of process in any litigation arising
out of or relating to this Agreement and the transactions contemplated hereby by
certified mail, return receipt  requested,  postage prepaid to it at its address
for notice specified in Section 12.04.

          Section  12.07  Agent  for  Service;  Waiver  of  Limitations.  By the
execution and delivery of this Agreement,  Adecco (i) acknowledges that it will,
by separate  written  instrument,  designate and appoint RL&F Service Corp., One
Rodney  Square,  Wilmington,  Delaware  19801 (and any successor  entity) as its
authorized  agent upon  which  process  may be served in any suit or  proceeding





                                       56
<PAGE>
arising out of or relating to this  Agreement or the  transactions  contemplated
hereby and acknowledges that RL&F Service Corp. will accept such designation and
(ii) agrees that service of process upon RL&F Service Corp.  and written  notice
of said service to Adecco in  accordance  with Section  12.04 shall be deemed in
every  respect  effective  service  of process  upon  Adecco in any such suit or
proceeding.  To the extent that Adecco has or hereafter may acquire any immunity
from  jurisdiction  of any  court or from any  legal  process  (whether  through
service of notice, attachment prior to judgment, attachment in aid of execution,
execution  or  otherwise)  with  respect  to itself or its  property,  it hereby
irrevocably  waives  such  immunity  in  respect of its  obligations  under this
Agreement and the  transactions  contemplated  hereby to the extent permitted by
law.

          Section 12.08 Waiver of Jury Trial and Certain Damages.  Each party to
this Agreement  waives,  to the fullest extent  permitted by applicable law, (a)
any  right it may  have to a trial by jury in  respect  of any  action,  suit or
proceeding arising out of or relating to this Agreement and (b) any right it may
have to receive  damages  from any other party based on any theory of  liability
for any special,  indirect,  consequential  (including lost profits) or punitive
damages; provided, however, that CLAUSE (B) OF this section 12.08 does not apply
to section  10.04 AND SHALL IN NO WAY LIMIT ANY RIGHTS OF ADECCO  THEREUNDER  OR
WITH RESPECT THERETO.

          Section 12.09  Counterparts.  This Agreement may be executed in two or
more counterparts,  each of which shall be deemed an original,  but all of which
together shall constitute one and the same instrument.

          Section 12.10 Severability.  In case any one or more of the provisions
contained in this Agreement  should be invalid,  illegal or unenforceable in any
respect against a party hereto, the validity, legality and enforceability of the
remaining  provisions  contained  herein  shall  not in any way be  affected  or
impaired thereby and such invalidity,  illegality or unenforceability shall only
apply as to such party in the specific jurisdiction where such judgment shall be
made.

          Section  12.11  Interpretation.   The  article  and  section  headings
contained in this  Agreement  are solely for the purpose of  reference,  are not
part of the agreement of the parties and shall not in any way affect the meaning
or  interpretation  of this Agreement.  As used in this Agreement,  (i) the term
"Person" shall mean and include an individual, a partnership, a joint venture, a
corporation,  a trust, an  unincorporated  organization  and a government or any
department  or  agency  thereof;  (ii) the term  "Subsidiary"  of any  specified

specified  corporation,  any  person  of which  such  corporation  is a  general
partner,  or any  other  person  of  which  at least a  majority  of the  equity
interests  therein  is,  directly or  indirectly,  owned or  controlled  by such
specified  corporation;  (iii) "$" or dollars shall mean the lawful  currency of
the United  States of America and (iv) "CHF"  shall mean the lawful  currency of

that the obtaining of the consents and approvals,  the execution and delivery of
any  amendatory  agreements  and the  making  of the  filings  and  applications
contemplated  by this  Agreement  shall  satisfy  the  provisions  of any or all
applicable agreements or the requirements of all applicable laws or judgments.

          (b) OHS represents and warrants that:

          (i) OHS is a corporation duly organized,  validly existing and in good
     standing  under the laws of the  State of  Delaware  and has all  requisite
     corporate  power and authority to own, lease and operate its properties and

          (ii) OHS has full  corporate  power  and  authority  to  execute  this
     Agreement and the  Ancillary  Agreements to which it will be a party and to
     consummate the transactions  contemplated hereby and thereby. The execution
     and  delivery  of this  Agreement  and  the  Ancillary  Agreements  and the
     consummation of the transactions  contemplated hereby and thereby have been
     duly  authorized  by all  necessary  action on the part of OHS and,  to the
     extent  required,  by the  stockholder of OHS. This Agreement has been duly
     executed and delivered by OHS and,  assuming due  authorization,  execution
     and delivery hereof by Olsten, constitutes a valid and binding agreement of
     OHS,  enforceable  against OHS in accordance with its terms,  except to the
     extent that its  enforceability  may be limited by  applicable  bankruptcy,
     insolvency,   reorganization,   moratorium  or  other  laws  affecting  the
     enforcement  of  creditors'   rights  generally  or  by  general  equitable
     principles.  Each of the  Ancillary  Agreements  will be duly  executed and
     delivered  by OHS on or prior  to the  Effective  Time  and,  assuming  due
     authorization,  execution and delivery thereof by each other party thereto,
     will constitute a valid and binding agreement of OHS,  enforceable  against
     OHS  in  accordance  with  its  terms,   except  to  the  extent  that  its
     enforceability  may  be  limited  by  applicable  bankruptcy,   insolvency,
     reorganization,  moratorium  or other laws  affecting  the  enforcement  of
     creditors' rights generally or by general equitable principles;

          (iii) The  execution  and  delivery by OHS of this  Agreement  and the
     Ancillary Agreements and the consummation of the transactions  contemplated
     hereby or thereby will not  contravene,  violate,  result in a breach of or
     constitute a default under (x) any  provision of  applicable  law or of the
     articles of incorporation or by-laws of OHS or any Health Subsidiary or (y)
     any judgment,  order, decree,  statute, law, ordinance,  rule or regulation
     applicable to OHS or any Health  Subsidiary  or any of their  properties or
     assets,  except for such  contravention,  violations,  breaches or defaults
     that,  individually or in the aggregate,  would not materially impair OHS's
     ability  to  consummate  the  transactions  contemplated  hereby or (z) the
     Governmental Settlement Agreements;

          (iv) No filing or registration with, or permit, authorization, consent
     or  approval  of,  or  notification  or  disclosure  to,  any  Governmental
     Authority is required by OHS in connection  with the execution and delivery
     of this  Agreement,  the Ancillary  Agreements or the  consummation  of the
     transactions  contemplated hereby or thereby, except (w) in connection with
     the  provisions  of the  Securities  Act and the  Exchange  Act,  (x)  such
     consents,  approvals,  orders,  permits,   authorizations,   registrations,
     declarations  and  filings  as may be  required  under the Blue Sky laws of
     various states,  (y) consents,  authorizations,  approvals or notifications
     listed on Schedule 6 and (z) such  consents,  approvals,  orders,  permits,
     authorizations,  registrations,  declarations  and filings,  the failure of
     which to obtain would not,  individually  or in the  aggregate,  materially
     impair OHS's  ability or Olsten's  ability to consummate  the  transactions
     contemplated hereby;

          (v) The OHS Common  Stock to be issued  pursuant  to Section  2.02 has
     been duly  authorized  and,  when so issued,  will be fully  paid,  validly
     issued and  nonassessable and will not have been issued in violation of any
     preemptive rights;






                                      -11-

          (vi)  At the  Effective  Time,  neither  OHS  nor  any  of the  Health
     Subsidiaries  will be a party to any  material  agreement,  arrangement  or
     understanding  with Olsten or any of the Retained  Subsidiaries  other than
     this Agreement,  the Ancillary  Agreements and any other agreement  entered
     into in connection  with the Split-Off as  contemplated  by this Agreement;
     and

          (vii) Each of the  Balance  Sheet and the balance  sheets  attached as
     Schedule 5 for the years ended January 4, 1999 and December 28, 1997 fairly
     present in all material  respects the  combined  financial  position of the
     Health Services  Business as of their respective  dates, in accordance with
     US GAAP  (subject in the case of interim  financial  statements,  to normal
     year-end adjustments).

          (c) In addition to the actions specifically  provided for elsewhere in
this  Agreement and except as otherwise  expressly set forth in this  Agreement,
each of the  parties  hereto  shall  act in good  faith  and use its  respective
reasonable  best efforts to take,  or cause to be taken,  all  actions,  and, to
execute and deliver,  or cause to be executed  and  delivered,  such  additional
documents  and  instruments,  and  to do,  or  cause  to be  done,  all  things,
reasonably  necessary,  proper or advisable under applicable laws and agreements
to  consummate  and  make  effective  the  transactions   contemplated  by  this
Agreement.

          (d) Notwithstanding anything contained herein to the contrary, neither
Olsten nor OHS shall,  without  the prior  written  consent of Adecco,  take any
action or inaction in effecting  the  transactions  contemplated  hereby if such
action or inaction  would (i) materially  increase the  Liabilities of Olsten or
the Retained  Subsidiaries,  (ii) materially  impair Olsten's ability to conduct
the Retained Businesses,  or (iii) materially decrease the value of the Retained
Assets.

          Section 2.06. Final  Determination  of Assets and Liabilities.  (a) In
case  of any  dispute  arising  before  the  Split-Off,  as to the  identity  or
existence of Assets  relating to the operation of the Health  Services  Business
and the  Retained  Businesses  or the  existence of such a  relationship  or the
transferability  thereof,  or the allocation of insurance  premium refunds,  the
good faith determination of the Board of Directors of Olsten,  together with the
consent of Adecco,  which consent shall not be  unreasonably  withheld,  if such
dispute shall concern Assets or Liabilities  that are material to Olsten and the
Retained Subsidiaries,  taken as a whole, if made before the Split-Off, shall be
final, conclusive and binding.

          (b) In case of any  dispute  arising  before the  Split-Off  as to the
identity or existence of Liabilities, to be assumed by OHS or as to which OHS is
to  indemnify  Olsten  and its  subsidiaries,  or the  identification  or  other
allocation of Liabilities in respect of insurance premium obligations,  the good
faith determination of the Board of Directors of Olsten,  together,  in the case
of a dispute which concerns  Assets or  Liabilities  that are material to Olsten
and the  Retained  Subsidiaries,  taken as a whole,  with the consent of Adecco,
which consent shall not be unreasonably  withheld, if made before the Split-Off,
shall be final, conclusive and binding.

further review.

basis  consistent with the  intercompany  loan balance  reflected on the Balance
Sheet.

          (c) On the True-Up  Date,  if the Net Debt of Olsten and the  Retained
Subsidiaries is (i) greater than $750 million, then the New Intercompany Account
shall reflect a payable by OHS to Olsten equal to the amount of such excess,  or
(ii) less than $750 million,  then Olsten shall pay to OHS cash on such date, in
an amount equal to such  shortfall or (iii) equal to $750 million,  then the New
Intercompany Account shall open with a zero balance.

          (d) At the Effective Time, (i) the Closing  Intercompany Balance shall
be settled by OHS or Olsten,  as the case may be, delivering to the other a cash

any,  together with simple interest at 6% per annum from the True-Up Date to the
Effective Time on the average daily balance,  and (ii) the True-Up  Intercompany
Balance shall be contributed to the capital of OHS at the Effective Time.

loans, between the Retained Businesses,  on the one hand and the Health Services
Business,  on the other, shall be reflected in the New Intercompany Account, and
(iii)  management fees shall be paid by OHS to Olsten on the same basis as prior
to the True-Up Date and shall be prorated to the Effective Time.

                                   ARTICLE IV

                                 INDEMNIFICATION


          Section  4.01.  OHS  Indemnification  of Olsten.  Except as  otherwise
expressly  provided  in any of the  Ancillary  Agreements,  from and  after  the
Closing  Date,  OHS shall  indemnify,  defend and hold  harmless  Olsten and its
subsidiaries,  and  each of their  respective  directors,  officers,  employees,
agents and Affiliates and each of the heirs,  executors,  successors and assigns
of any of the foregoing (the "Olsten  Indemnitees") from and against any and all
damage, loss, liability,  deficiency and expense (including, without limitation,
reasonable expenses of investigation and reasonable attorneys' fees and expenses
in  connection  with any or all such  investigations  or any and all  Actions or
threatened Actions) (collectively,  "Indemnifiable Losses") incurred or suffered
by any of the Olsten  Indemnitees  and  arising out of or related to (i) the OHS
Liabilities  or the  failure  of OHS or any of the Health  Subsidiaries  to pay,
perform or otherwise discharge any of the OHS Liabilities;  (ii) with respect to
information in the Olsten Proxy Statement, the OHS Registration Statement or the





                                      -15-
<PAGE>
Adecco  Registration  Statement related to the Health Services Business,  OHS or
any of the Health Subsidiaries or the Split-Off, any untrue statement or alleged
untrue statement of a material fact or any omission or alleged omission to state
therein  or  necessary  to  make  the   statements   therein  in  light  of  the
circumstances   under  which  they  were  made,   not   misleading;   (iii)  any
misrepresentation  or breach of any warranty in this Agreement made by OHS; (iv)
any breach of any agreement or covenant  under this  Agreement  made by OHS; (v)
liabilities  resulting  from  any  holder  of  Olsten  Common  Stock  exercising
appraisal rights under the Delaware General  Corporation Law with respect to the
value of the Split-Off Consideration;  and (vi) any cash paid to stockholders of
Olsten in lieu of fractional shares of OHS.

          Section  4.02.  Olsten  Indemnification  of OHS.  Except as  otherwise
expressly  provided  in any of the  Ancillary  Agreements,  from and  after  the
Closing  Date,  Olsten  shall  indemnify,  defend and hold  harmless OHS and the
Health  Subsidiaries,   and  each  of  their  respective  directors,   officers,
employees,  agents and Affiliates and each of the heirs,  executors,  successors
and assigns of any of the foregoing (the "OHS Indemnitees") from and against any
and all Indemnifiable  Losses incurred or suffered by any of the OHS Indemnitees
and  arising out of or related to (i) the Olsten  Liabilities  or the failure of
Olsten or any of its subsidiaries to pay, perform or otherwise  discharge any of
the Olsten  Liabilities  or (ii) any breach of any  agreement or covenant  under
this Agreement made by Olsten after the Closing Date.

          Section 4.03.  Notice and Payment of Claims.  If any Olsten Indemnitee
or OHS Indemnitee  (the  "Indemnified  Party")  determines  that it is or may be
entitled  to  indemnification  by  OHS  or  Olsten,  as the  case  may  be  (the
"Indemnifying  Party"), under this Article IV (other than in connection with any
Action  subject to Section  4.04),  the  Indemnified  Party shall deliver to the
Indemnifying  Party  a  written  notice  specifying,  to the  extent  reasonably
practicable,  the basis for its claim for  indemnification  and the  amount  for
which  the  Indemnified   Party  reasonably   believes  it  is  entitled  to  be
Indemnified. After the Indemnifying Party shall have been notified of the amount
for which the Indemnified Party seeks  indemnification,  the Indemnifying  Party
shall,  within  15  days  after  receipt  of  such  notice,  either  (i) pay the
Indemnified Party such amount in cash or other  immediately  available funds (or
reach  agreement  with  the  Indemnified  Party  as  to  a  mutually   agreeable
alternative payment schedule) or (ii) object to the claim for indemnification or
the amount thereof by giving the Indemnified  Party written notice setting forth
the grounds therefor. Any objection shall be resolved in accordance with Section
7.15.  If the  Indemnifying  Party does not give such notice,  the  Indemnifying
Party shall be deemed to have  acknowledged its liability for such claim and the
Indemnified Party may exercise any and all of its rights under applicable law to
collect such amount.

          Section 4.04. Notice and Defense of Third-Party  Claims.  (a) Promptly
following the earlier of (a) receipt of written notice of the  commencement by a
third party of any Action against or otherwise  involving any Indemnified Party,
or (b) receipt of written  information from a third party alleging the existence
of a claim against an Indemnified  Party,  in either case, with respect to which
indemnification  may be  sought  pursuant  to  this  Agreement  (a  "Third-Party
Claim"),  the Indemnified Party shall give the Indemnifying Party prompt written
notice thereof.  The failure of the Indemnified Party to give notice as provided
in this Section 4.04 shall not relieve the Indemnifying Party of its obligations





                                      -16-
<PAGE>
under  this  agreement,  except to the  extent  that the  Indemnifying  Party is
prejudiced  by such  failure to give  notice.  Such notice  shall  describe  the
Third-Party  Claim in  reasonable  detail and shall  indicate  the amount of the
Indemnifiable Loss that has been or will be sustained by the Indemnified Party.

          (b) Within 30 days  after  receipt of such  notice,  the  Indemnifying
Party may,  by giving  written  notice  thereof to the  Indemnified  Party,  (i)
acknowledge  liability for and at its option elect to assume the defense of such
Third-Party  Claim at its sole cost and expense,  or (ii) object to the claim of
indemnification  for such Third-Party  Claim setting forth the grounds therefor.
Any  objection  shall be  resolved  in  accordance  with  Section  7.15.  If the
Indemnifying Party does not within such 30-day period give the Indemnified Party
such notice,  the  Indemnifying  Party shall be deemed to have  acknowledged its
liability for such Third-Party Claim.

          (c) Any defense of a  Third-Party  Claim as to which the  Indemnifying
Party has elected to assume the defense shall be conducted by attorneys employed
by the Indemnifying  Party and reasonably  satisfactory to Olsten in the case of
Olsten Indemnitees and OHS in the case of OHS Indemnitees. The Indemnified Party
shall have the right to participate in such proceedings and to be represented by
attorneys of its own choosing at the Indemnified  Party's sole cost and expense;
provided that if the defendants or parties against which relief is sought in any
such  claim  include  both the  Indemnifying  Party and one or more  Indemnified
Parties  and,  in the  reasonable  judgment  of  Olsten  in the  case of  Olsten
Indemnitees  and OHS in the case of OHS  Indemnitees,  a  conflict  of  interest
between such Indemnified  Parties and such Indemnifying  Party exists in respect
of such claim, such Indemnified  Parties shall have the right to employ one firm
of counsel  selected by Olsten or OHS, as the case may be, and in that event the
reasonable  fees and  expenses of such  separate  counsel (but not more than one
separate counsel  reasonably  satisfactory to the  Indemnifying  Party) shall be
paid by such Indemnifying Party.

          (d) If the  Indemnifying  Party  assumes the defense of a  Third-Party
Claim,  the  Indemnifying  Party may settle or compromise  the claim without the
prior written consent of the Indemnified Party;  provided that without the prior
written consent of Olsten in the case of Olsten  Indemnitees and OHS in the case
of OHS Indemnitees,  the Indemnifying Party may not agree to any such settlement
unless as a  condition  to such  settlement  the  Indemnified  Party  receives a
written release from any and all liability  relating to such  Third-Party  Claim
and such  settlement or  compromise  does not include any remedy or relief to be
applied to or against the  Indemnified  Party,  other than monetary  damages for
which the Indemnifying Party shall be responsible hereunder.

          (e) If the  Indemnifying  Party  does  not  assume  the  defense  of a
Third-Party  Claim for which it has acknowledged  liability for  indemnification
under this Article IV, Olsten in the case of Olsten  Indemnitees  and OHS in the
case of OHS  Indemnitees  may pursue the defense of such  Third-Party  Claim and
choose one firm of counsel in connection  therewith.  The Indemnifying  Party is
required to reimburse  Olsten or OHS, as the case may be, on a current basis for
its  reasonable  expenses  of  investigation,  reasonable  attorney's  fees  and
reasonable  out-of-pocket  expenses  incurred  by  Olsten  in the case of Olsten
Indemnitees  and OHS in the case of OHS  Indemnitees  in defending  against such
Third-Party  Claim  and the  Indemnifying  Party  shall be  bound by the  result
obtained with respect thereto; provided that the Indemnifying Party shall not be
liable for any settlement  effected without the consent of Olsten in the case of
Olsten  Indemnitees and OHS in the case of OHS Indemnitees,  which consent shall
not be unreasonably withheld.


                                      -17-
<PAGE>
          (f) The Indemnifying  Party shall pay to the Indemnified Party in cash
the amount for which the  Indemnified  Party is entitled to be  indemnified  (if
any)  within 15 days  after  the  final  resolution  of such  Third-Party  Claim
(whether  by  the  final   nonappealable   judgment  of  a  court  of  competent
jurisdiction or otherwise) or, in the case of any Third-Party  Claim as to which
the Indemnifying Party has not acknowledged liability, within 15 days after such
Indemnifying Party's objection has been resolved pursuant to Section 7.15.

          Section 4.05.  Insurance  Proceeds.  The amount that any  Indemnifying
Party is or may be required  to pay to any  Indemnified  Party  pursuant to this
Article IV shall be reduced (including,  without  limitation,  retroactively) by
any insurance  proceeds or other amounts  actually  recovered by or on behalf of
such Indemnified  Parties in reduction of the related  Indemnifiable Loss. If an
Indemnified  Party shall have  received the payment  required by this  Agreement
from an  Indemnifying  Party in  respect  of an  Indemnifiable  Loss  and  shall
subsequently actually receive insurance proceeds, or other amounts in respect of
such  Indemnifiable  Loss as specified above,  then such Indemnified Party shall
pay to such  Indemnifying  Party a sum  equal to the  amount  of such  insurance
proceeds or other amounts actually received after deducting therefrom all of the
Indemnified  Party's costs and expenses associated with the recovery of any such
amount.

          Section 4.06.  Contribution.  If the  indemnification  provided for in
this  Article  IV is  unavailable  to an  Indemnified  Party in  respect  of any
Indemnifiable  Loss  arising  out of or related to  information  about OHS,  the
Health Subsidiaries or the Health Services Business contained in or omitted from
the OHS Registration Statement,  the Adecco Registration Statement or the Olsten
Proxy Statement, then OHS, in lieu of indemnifying the Olsten Indemnitees, shall
contribute to the amount paid or payable by the Olsten  Indemnitees  as a result
of such  Indemnifiable  Loss in such proportion as is appropriate to reflect the
relative  fault of OHS,  on the one hand,  and  Olsten,  on the other  hand,  in
connection with the statements or omissions that resulted in such  Indemnifiable
Loss.  The  relative  fault  of the OHS  Indemnitees  on the one hand and of the
Olsten  Indemnitees on the other hand shall be determined by reference to, among
other things,  whether the untrue or alleged untrue statement of a material fact
or the  omission  or  alleged  omission  to state a  material  fact  relates  to
information concerning OHS on the one hand or Olsten on the other hand.

          Section 4.07. Subrogation.  In the event of payment by an Indemnifying
Party to any Indemnified  Party in connection with any Third-Party  Claim,  such
Indemnifying  Party shall be  subrogated to and shall stand in the place of such
Indemnified  Party as to any  events or  circumstances  in respect of which such
Indemnified  Party  may have any  right or claim  relating  to such  Third-Party
Claim. Such Indemnified Party shall cooperate with such Indemnifying  Party in a
reasonable  manner,  and at the cost and expense of such Indemnifying  Party, in
prosecuting any subrogated right or claim.

          Section 4.08. Third-Party  Beneficiaries.  This Article IV shall inure
to the  benefit  of, and be  enforceable  by,  Olsten,  OHS and Adecco and their
respective successors and permitted assigns. The indemnification provided for by
this  Article  IV shall not inure to the  benefit  of any other  third  party or
parties and shall not relieve any insurer who would  otherwise  be  obligated to
pay any claim of the responsibility with respect thereto or, solely by virtue of
the  indemnification  provisions  hereof,  provide any  subrogation  rights with
respect  thereto and each Party agrees to waive such rights against the other to
the fullest extent permitted.

<PAGE>
          Section  4.09.  Remedies  Cumulative.  The  remedies  provided in this
Article  IV  shall  be  cumulative  and  shall  not  preclude  assertion  by any
Indemnified  Party of any  other  rights  or the  seeking  of any and all  other
remedies against any Indemnifying Party.

          Section 4.10.  Survival of  Indemnities.  The  obligations  of each of
Olsten and OHS under this Article IV shall survive the sale or other transfer by
it of any Assets or businesses or the assignment by it of any Liabilities,  with
respect  to any  Indemnifiable  Loss  of  the  other  related  to  such  Assets,
businesses or Liabilities.

          Section 4.11. After-Tax  Indemnification Payments. Except as otherwise
expressly  provided  herein or in an Ancillary  Agreement,  any  indemnification
payment made by any  Indemnifying  Party under this Article IV shall be computed
by taking into account the value of any and all applicable  deductions,  losses,
credits,  offsets  or other  items  for  Federal,  state or other  tax  purposes
attributable  to the payment of the  indemnified  liability  by the  Indemnified
Party and any Tax incurred by the Indemnified  Party  attributable to receipt of
the indemnification payment.


                                    ARTICLE V

          Section 5.03. OHS Certificate of Incorporation  and By-laws.  Prior to

remit payment of the Transaction Taxes and OHS will join in the execution of any
such tax returns or other documentation. Payment of all Transaction Taxes, other

each of the trade marks, trade names, service marks and other proprietary rights
exclusively related to such OHS Names and any trade marks, trade names,  service

Effective  Time (the "OHS  Proprietary  Name  Rights").  Following the Effective
Time,  Olsten  and each of the  Retained  Subsidiaries  shall  have the sole and
exclusive  ownership  of and  right  to use,  as  between  OHS  and  the  Health

and other  proprietary  rights  related to such Olsten  Names other than the OHS
Proprietary Name Rights and any trade marks, trade names, service marks or other
proprietary rights mutually agreed among the parties prior to the Effective Time
(the "Olsten  Proprietary  Name Rights").  Notwithstanding  the foregoing,  with
respect to the Olsten Names and Olsten  Proprietary Name Rights which are listed
on Schedule 8 (the  "Licensed  Olsten  Names"),  Olsten hereby grants to OHS and
each of the Health Subsidiaries, a royalty-free license in order for OHS and the
Health  Subsidiaries  to continue to use the Licensed  Olsten Names and have the
full  privileges of a licensee  with respect to the Licensed  Olsten Names for a
period of one year following the Effective Time.

          (b) Following the Effective  Time, (x) OHS shall,  and shall cause its
subsidiaries  and other Affiliates to, take all action  reasonably  necessary to
cease  using,  and  change as soon as  commercially  practicable  (including  by
amending any charter documents), any corporate or other names which are the same
as or  confusingly  similar  to any of the  Olsten  Names  or any of the  Olsten
Proprietary Name Rights,  and (y) Olsten shall, and shall cause its subsidiaries
and other  Affiliates to, take all action  reasonably  necessary to cease using,
and  change as soon as  commercially  practicable  (including  by  amending  any

confusingly  similar to any of the OHS Names or any of the OHS Proprietary  Name
Rights.

          (c) The license granted  pursuant to Section 5.06(a) shall include the
right to use existing brochures,  stationery,  labeling,  supplies,  advertising
materials,  office  materials  and any similar  materials  bearing any  Licensed
Olsten Names until the earlier of (i) the  termination of the license,  and (ii)
the date such  existing  materials  are  exhausted  and Olsten and the  Retained
Subsidiaries  shall  have  the  right  to use  existing  brochures,  stationery,
labeling,  supplies,  advertising  materials,  office  materials and any similar
materials  bearing  any OHS Names  until the  earlier  of (i) one year after the
Effective Time and (ii) the date such existing materials are exhausted; provided
that each such Party shall use their reasonable best efforts to (a) replace such
materials  with  materials  that do not use the  other's  names as  promptly  as

affixed to such materials that the name being used is being used under temporary

          Section 5.07. Mail. After the Closing Date, each of Olsten and OHS may
receive mail, telegrams, packages and other communications properly belonging to
the other.  Accordingly,  at all times after the Effective  Time, each of Olsten
and OHS authorizes the other to receive and open all mail,  telegrams,  packages
and other communications  received by it and not unambiguously  intended for the
other party or any of the other party's  officers or directors  specifically  in
their  capacities as such, and to retain the same to the extent that they relate
to the business of the receiving party or, to the extent that they do not relate
to the  business  of the  receiving  party and do relate to the  business of the
other party, or to the extent that they relate to both businesses, the receiving
party  shall  promptly  contact  the  other  party  by  telephone  for  delivery
instructions and such mail, telegrams,  packages or other communications (or, in
case the same  relate to both  businesses,  copies  thereof)  shall  promptly be
forwarded to the other party in accordance with its delivery  instructions.  The
foregoing provisions of this Section 5.07 shall constitute full authorization to
the postal  authorities,  all  telegraph  and  courier  companies  and all other
persons to make  deliveries  to Olsten or OHS, as the case may be,  addressed to
either of them or to any of their  officers or directors  specifically  in their
capacities as such.  The provisions of this Section 5.07 are not intended to and
shall not be deemed to  constitute an  authorization  by either Olsten or OHS to
permit the other to accept  service of process on its behalf,  and neither party
is or shall be  deemed  to be the agent of the  other  for  service  of  process
purposes or for any other purpose.

          Section 5.08.  Transition  Services.  Following the Effective Time and
ending on the one year  anniversary  of the  Effective  Time (such  period,  the
"Transition  Services  Period"),  Olsten shall use its  commercially  reasonable
efforts to provide, or make available,  to OHS and the Health  Subsidiaries,  at
such  times and in such  amounts  as may be  reasonably  requested  by OHS,  the
following  services  (the  "Transition  Services")  and OHS  will  pay for  such
Transition Services on a cost basis as agreed to by the parties:

          (i) tax preparation and filing services;

          (ii) legal  services,  to be provided by Olsten's  general counsel and
     other internal counsel to the extent  consistent with applicable  standards
     of professional responsibility;

          (iii) information and technology  support services and  administrative
     and office services;

          (iv)    procurement services; and

          (v) such other additional  services as may be reasonably  requested by
     OHS;  provided that the scope of any services,  as well as the time and the
     manner  in which  such  services  are to be  provided,  shall  be  mutually
     agreeable between the parties.

          Following  the end of the  calendar  month  in  which  any  Transition
Services are performed,  Olsten shall provide to OHS an invoice (the "Transition
Services Invoice") setting forth in summary detail the Transition Services which
were provided during such calendar month and the appropriate  cost thereof.  OHS
shall pay Olsten,  in a reasonably  prompt manner (but in no event later than 30
days)  following the delivery by Olsten of a Transition  Services  Invoice,  the
amounts due with respect to the Transition Services reflected on such Transition
Services Invoice.



                                      -21-
<PAGE>
          Notwithstanding  anything  herein  to  the  contrary,  all  Transition
Services shall be performed with reasonable care, but no Party hereto shall have
any  liability  whatsoever  to any other  Party or any third party for any loss,
liability, damage, cost or deficiency suffered by any such person arising out of
or resulting from providing any Transition Services hereunder.

          Section  5.09.  Leases  of Real  Property.  (a)  Olsten  and OHS shall
jointly  and  promptly  review  all  instances  in which  (i) OHS or the  Health
Subsidiaries  maintain  facilities in, or otherwise occupy, real property leased
by  Olsten  or the  Retained  Subsidiaries  and  (ii)  Olsten  or  the  Retained
Subsidiaries maintain facilities in or otherwise occupy, real property leased by
a Health Subsidiary, each as set forth on Schedule 7, and shall use commercially
reasonable efforts in each case to either (x) negotiate and enter into a written
lease or  sublease  incorporating  terms and  conditions  which are fair to both
parties,  (y) assign such lease to OHS or Olsten, as the case may be, and OHS or
Olsten, as the case may be, shall accept  responsibility  for such lease, or (z)
terminate the arrangement on mutually agreeable terms;  provided,  however, that
the  foregoing  shall  not  apply  in  any  instance  (A)  involving  facilities
maintained,  or real property occupied by the Health Subsidiaries that are to be
transferred  to OHS in accordance  with Section 2.01 or (B) covered by a written
lease agreement between the parties in effect on the date hereof.

          (b) OHS  agrees  that  it will  use its  reasonable  best  efforts  to
promptly  (but in no event  later than six  months)  after the  Effective  Time,
relocate the headquarters for the Health Services Business from 175 Broad Hollow
Road, Melville,  New York 11747 (the "Main  Headquarters").  Until the time when
the  headquarters  of the Health  Service  Business  is  relocated  OHS shall be
entitled to occupy and use without charge office space at the Main Headquarters,
as shall be  reasonably  designated by Olsten as necessary to enable OHS and the
Health Subsidiaries to continue to conduct its current operations.

          Section 5.10. Plea Agreements.  OHS agrees to be bound by the terms of
the Plea Agreements  dated July 19, 1999 between Kimberly Home Health Care, Inc.
and the United States of America,  including those terms governing the retention
and production of information, records and testimony.

          Section  5.11.  Insurance  Policies  and  Claims  Administration.  (a)
Policies and Rights Included Within the Transferred OHS Assets.  The Transferred
OHS Assets shall include: (i) any Health Services Business Policies and (ii) any
and all rights of the Health Subsidiaries under any Shared Policies covering (x)
Liabilities  arising out of or  relating  to the conduct of the Health  Services
Business  prior to the  Effective  Time and (y)  Liabilities  arising  out of or
relating to the conduct of the Retained  Businesses  prior to the Effective Time
to the extent any claim is made  against  OHS or any of the Health  Subsidiaries
for such Liabilities, specifically including (in the case of (i) and (ii) above)
rights of  indemnity  and the right to be  defended  by or at the expense of the
insurer,  with respect to all claims,  suits,  actions,  proceedings,  injuries,
losses,  liabilities,  damages and  expenses  and  excluding  rights  covered by
Section 5.11(b).










                                      -22-
<PAGE>
          (b)  Policies and Rights  Included  Within the  Retained  Assets.  The
Retained Assets shall include: (i) any Retained Businesses Policies and (ii) any
and all rights of Olsten and its subsidiaries under any Shared Policies covering
(x)  Liabilities  arising  out of or  relating  to the  conduct of the  Retained
Businesses  prior to the Effective  Time and (y)  Liabilities  arising out of or
relating to the conduct of the Health  Services  Business prior to the Effective
Time to the  extent  any claim is made  against  Olsten  or any of the  Retained
Subsidiaries for such  Liabilities,  specifically  including (in the case of (i)
and (ii) above)  rights of  indemnity  and the right to be defended by or at the
expense of the insurer, with respect to all claims, suits, actions, proceedings,
injuries, losses, liabilities, damages and expenses.

          (c) Olsten to Maintain Insurance Coverage Prior to Effective Time. (i)
Olsten  shall use its  reasonable  best  efforts to  maintain  in full force and
effect,  at all times up to and including the Effective  Time,  the Policies and
current coverages and limits of such Policies.

          (ii) To the extent not already  provided  for by the terms of a Shared
Policy,  Olsten shall use its commercially  reasonable  efforts to cause OHS and
the Health  Subsidiaries,  as  appropriate,  to be named as additional  insureds
under each such Policy in respect of Covered  Claims  arising out of or relating
to  periods  prior  to the  Effective  Time;  provided,  however,  that  nothing
contained  herein shall be  construed  to require  Olsten or any of the Retained
Subsidiaries  to pay any  additional  premium or other charges in respect to, or
waive or otherwise limit any of its rights,  benefits or privileges  under,  any
Shared  Policy to effect the naming of OHS and the Health  Subsidiaries  as such
additional insureds.

          (d) OHS Responsible for Establishing  Insurance  Coverage on and After
Effective Time.  Commencing on and as of the Effective Time, OHS and each of the
Health  Subsidiaries  shall be responsible for  establishing and maintaining its
own separate insurance programs for activities and claims relating to any period
on or after the Effective Time involving OHS or any of the Health  Subsidiaries.
Notwithstanding any other agreement or understanding to the contrary,  except as
set forth in Section  5.11(e)(i) and (ii) with respect to claims  administration
and  financial  administration  of the  Shared  Policies,  as of and  after  the
Effective Time,  neither Olsten nor any of the Retained  Subsidiaries shall have
any responsibility for or obligation to OHS or the Health Subsidiaries  relating
to insurance matters for any period, whether prior to, at or after the Effective
Time. Notwithstanding the foregoing, from the date hereof to the Effective Time,
Olsten shall use its commercially  reasonable efforts to transfer to OHS and the
Health  Subsidiaries  the  Health  Services  Business  Policies  and  to  obtain
insurance  (or  binders  therefor)  providing  coverage  to OHS and  the  Health
Subsidiaries similar to the coverage provided to the Health Services Business by
the Shared Policies prior to the Split-Off.

          (e) Administration and Procedure. (i) OHS and its subsidiaries appoint
Olsten or a Retained Subsidiary,  as appropriate,  to administer, in good faith,
all  claims  and  finances  relating  to  the  Shared  Policies,  including  the
prosecution  of any  actions  for  declaratory  relief,  "bad  faith"  or  other
extra-contractual  damages.  From and  after  the  Effective  Time,  Olsten or a
Retained  Subsidiary,  as  appropriate,  shall  be  responsible  for the  claims
administration  and financial  administration of all Shared Policies relating to
the assets,  ownership or operation  prior to the  Effective  Time of the Health





                                      -23-
<PAGE>
Services  Business;  provided,  however,  that  the  responsibility  for  claims
administration and financial administration of the Shared Policies are in no way
intended to limit, inhibit or preclude any right to insurance coverage under the
Shared Policies.  Olsten shall be entitled to compensation for and reimbursement
of expenses incurred in connection with performing the claims administration and
financial  administration  of the Shared  Policies on a cost basis, as agreed by
the parties and Olsten and OHS shall  comply with the  provisions  of the second
paragraph  of Section  5.08 with  respect to billing and  reimbursement.  Olsten
shall use  reasonable  care and act in good  faith  with  respect to each of its
obligations under Section 5.11.

          (ii) OHS shall promptly notify Olsten of any Covered Claim relating to
OHS or any Health  Subsidiary under one or more of the Shared Policies  relating
to any period  prior to the  Effective  Time,  and OHS agrees to  cooperate  and
coordinate with Olsten  concerning any strategy  Olsten may reasonably  elect to
pursue to secure  coverage and payment for such Covered Claim by the appropriate
insurance  carrier.  Olsten shall have final authority to compromise,  settle or
otherwise  resolve  any claim or  action  under any  Shared  Policy,  including,
without  limitation,  decisions to prosecute any action for declaratory  relief,
"bad faith" or other extra-contractual  damages;  provided, that, as a condition
to any compromise or settlement of any such claim or action on behalf of OHS (x)
Olsten  obtains a written  release on behalf of OHS for such claim or action and
(y) if such settlement or compromise  includes any remedy or relief against OHS,
other than monetary damages within the coverage limits of the applicable  Shared
Policy,  Olsten shall, prior to entering into any such compromise or settlement,
obtain the consent of OHS,  which  consent shall not be  unreasonably  withheld.
Notwithstanding  anything  contained  herein,  in any other  agreement or Shared
Policy or any  understanding  to the  contrary,  OHS or the  appropriate  Health
Subsidiary  assumes  responsibility  for,  and  shall  pay  to  the  appropriate
insurance carriers or otherwise,  any premiums,  reporting endorsements,  tails,
noses, retroactive endorsements,  retrospectively-rated premiums, defense costs,
indemnity  payments,  deductibles,  retentions or other charges,  as appropriate
(collectively,  "Insurance Charges"),  whenever arising,  which shall become due
and payable  under the terms and  conditions  of any Shared Policy in respect of
any liabilities,  losses,  claims,  actions or occurrences,  whenever arising or
becoming  known,  involving  or  relating  to  any of  the  assets,  businesses,
operations or liabilities of the Health Services Business,  which charges relate
to the period  after the  Effective  Time.  To the extent  that the terms of any
applicable  Shared  Policy  provide  that  Olsten or a Retained  Subsidiary,  as
appropriate,  shall have an  obligation  to pay or guarantee  the payment of any
Insurance  Charges,  Olsten or such  Retained  Subsidiary  shall be  entitled to
demand that OHS or a Health  Subsidiary make such payment directly to the person
or entity entitled  thereto.  In connection  with any such demand,  Olsten shall
submit to OHS or a Health Subsidiary a copy of any invoice received by Olsten or
any Retained  Subsidiary  pertaining to such  Insurance  Charges,  together with
appropriate supporting documentation, if available. In the event that OHS or any
of the  Health  Subsidiaries  fails to pay any  Insurance  Charges  when due and
payable,  whether at the request of the party entitled to payment or upon demand
by Olsten or a Retained  Subsidiary,  Olsten or a Retained  Subsidiary  may (but
shall not be required to) pay such Insurance Charges for and on behalf of OHS or
the  Health  Subsidiary  and,  thereafter,  OHS or the Health  Subsidiary  shall
forthwith reimburse Olsten or the Retained Subsidiaries for such payment.







                                      -24-
<PAGE>
          (iii) OHS or a Health Subsidiary, as appropriate, shall be responsible
for all Insurance Charges claims administration and financial administration and
risk management  programs  relating to the Health Services Business Policies and
any  insurance  policies  established  and  maintained  by OHS  and  the  Health
Subsidiaries  for claims  relating to any period on or after the Effective  Time
involving OHS or any of the Health Subsidiaries.

          (f)  Allocation of Insurance  Proceeds of Shared  Policies.  Insurance
Proceeds  received with respect to claims,  costs and expenses  under the Shared
Policies  shall be paid to Olsten with  respect to Covered  Claims of Olsten and
shall be paid to OHS with respect to  Liabilities  related to Covered  Claims of
OHS. Payment of the allocable  portions of indemnity costs of Insurance Proceeds
resulting  from  Shared  Policies  will be made to the  appropriate  party  upon
receipt  from  the  insurance  carrier.  For  purposes  of the  prior  sentence,
Insurance  Proceeds shall include any damages paid or received from  prosecution
of claims on a Shared Policy for "bad faith" or  extra-contractual  damages.  In
the event that the aggregate  limits on any Shared  Policies are exceeded by the
aggregate outstanding Covered Claims by Olsten and the Retained Subsidiaries and
OHS and the Health  Subsidiaries  and any of the Covered Claims of Olsten or the
Retained  Subsidiaries  relate to Liabilities arising out of the Health Services
Business (including,  but not limited to, the Shareholder  Liabilities) prior to
the  Effective  Time,  Olsten  shall be  entitled  to be paid in full all of the
Insurance  Proceeds relating to such Liabilities of the Health Services Business
prior to payment of  Insurance  Proceeds  relating to any other claims of Olsten
and the Retained Subsidiaries or OHS and the Health Subsidiaries. Thereafter, or
in the  event  there  are no such  Liabilities  of Olsten  relating  the  Health
Services  Business prior to the Effective Time, the Insurance  Proceeds shall be
allocated pro rata to Olsten and the Retained Subsidiaries, on the one hand, and
OHS and the Health Subsidiaries,  on the other hand, based upon their respective
bona fide claims or in such other  proportions  as the parties shall agree based
on an equitable  allocation  of  Insurance  Proceeds.  The parties  agree to use
commercially  reasonable efforts to maximize available coverage under the Shared
Policies  applicable  to it, and to take all  commercially  reasonable  steps to
recover from all other responsible  parties in respect of a Covered Claim to the
extent  coverage  limits  under a Shared  Policy have been  exceeded or would be
exceeded as a result of such Insured Claim.

          (g) Agreement for Waiver of Conflict and Shared Defense.  In the event
that  Covered  Claims  of  both  Olsten  and  OHS  exist  relating  to the  same
occurrence,  Olsten and OHS agree to jointly defend and to waive any conflict of
interest necessary to the conduct of that joint defense. Nothing in this Section
5.11 shall be construed to limit or otherwise  alter in any way the  obligations
of the parties to this Agreement,  including those created by this Agreement, by
operation of law or otherwise.

          Section  5.12.  Financial  Covenants.  (a)  Immediately  prior  to the
Effective Time (after giving effect to the transactions contemplated herein):

          (i) Indebtedness  for borrowed money plus the deferred  purchase price

     of OHS and its subsidiaries  during the period between July 4, 1999 and the

     million per month during such period.

          (iv)  OHS will  have a  committed  credit  facility  with a  borrowing

          (b) Olsten and OHS jointly  represent,  warrant and covenant  that the
Retained  Businesses and the Health Services  Business  shall,  between the date
hereof and the Effective  Time,  be operated in the ordinary  course of business
consistent with past practice, in nature, manner and amount,  including,  to the
extent practicable, as to levels and relationships of asset, liability, revenue,
expense,  and cash flow items and totals within the  respective  businesses  (it
being  understood  that unpaid amounts in respect of settlements of governmental
liabilities with respect to health care operations on terms previously disclosed
to Adecco,  shall be considered  ordinary  course items).  Without  limiting the
generality of the foregoing,  with respect to Olsten, the Retained  Subsidiaries
and the Retained  Businesses  and,  through the True-Up Date, OHS and the Health
Services  Business,   neither  Olsten  nor  OHS  nor  any  of  their  respective
Subsidiaries  shall,  without the prior written  consent of Adecco,  directly or
indirectly:

          (i) authorize,  permit to make or make any capital  expenditures other
     than pursuant to the capital expenditure plan previously provided by Olsten
     to  Adecco,  or fail to  make  any  investments  for  capital  expenditures
     contemplated by such plan;

          (ii) permit or make any change to the billing  processes  for services
     rendered  or  otherwise,  other than as may be  related  to planned  system
     improvements  and  the  like,  or in the  processes,  method  or  terms  of
     collection of accounts receivable;

          (iii) cause or permit any discounting,  factoring or securitization of
     accounts  receivables  or any other  securitization  or  consignment of any
     assets;

          (iv) permit or make any change in the aging of accounts payables or in
     the payment  practices for accounts payable in effect as of the date hereof
     (which aging and payment practices are consistent with past practice); or

          (v) except for cash transfers made, in the ordinary course of business
     through and reflected in the  intercompany  loan balance,  sell,  transfer,
     pledge,  mortgage or otherwise dispose of or encumber any assets, except in
     the ordinary  course of business  and in  arms-length  transactions  and at
     market rates (with the parties  acknowledging that the management fees paid
     consistent with past practice fall within such exception).

          (c) To assure  conformity  with the provisions of clause (b) above and
the other  provisions  of this Section  5.12,  the parties  agree that it is the
intent of Section 5.03(a) of the Merger Agreement that representatives of Adecco
reasonably  acceptable  to Olsten  shall be  permitted  to be present on a daily
basis at the headquarters  and other facilities of Olsten to monitor  compliance
with  such  provisions,  and  Olsten  shall  fully  cooperate  with and make all
information  reasonably  requested  promptly  available  to  such  monitors.  In
addition,  and consistent with, and not by way of limitation of, Section 5.03(a)
of the Merger  Agreement,  the parties hereto agree and acknowledge  that Olsten
shall provide Adecco with (y) pro-forma  combined balance sheets,  statements of
income, statements of cash flows and statements of shareholders equity as of the
close of business on each of the True-Up  Date and the last day of each  monthly
period  thereafter up to the Closing Date of each of (i) Olsten and the Retained
Subsidiaries  and  (ii)  OHS and the  Health  Subsidiaries,  in each  case,  (A)
prepared in  accordance  with US GAAP and (B) giving effect to the Split-Off and
the  provisions of Section 2.09 hereof and (z) all work papers of Olsten and OHS
and, as applicable,  their respective  independent public accountants as of such
dates or related to such balance  sheets or statements and all other work papers
in respect of the  separation of the Health  Services  Business and the Retained
Businesses contemplated hereby.

          (d) The parties  agree that any breach of this  Section 5.12 by either
Olsten or OHS,  other than breaches which are  insignificant  in both nature and
effect,  shall  cause a  covenant  of this  Agreement  to have  been  materially
breached by Olsten for purposes of Section  10.01(g) of the Merger Agreement and
shall provide Adecco with the right to terminate the Merger  Agreement  pursuant
to such Section 10.01(g), subject to the cure right contained therein.

          Section 5.13. Tax Refund Escrow Account.  Olsten agrees to deposit any
cash  payments  received  prior to the  Effective  Time by  Olsten  from any Net
Operating  Loss Refund  Claim into an escrow  account  (the "Tax  Refund  Escrow
Account")  which shall not be removed from such account until the earlier of (i)
the Effective Time, and (ii) the termination of the Merger Agreement.

          Section 5.14. Worker's  Compensation Letters of Credit. On the Closing
Date, OHS agrees to issue,  or have issued on its behalf,  a letter of credit to
Olsten in an amount equal to the amount of worker's  compensation claims pending
on the Closing Date made by any OHS Employee  prior to the  Effective  Time,  as
such amount is mutually  agreed upon among the parties  hereto,  determined on a
basis consistent with the Balance Sheet.

registers,  stock  certificates,  documents  of title,  etc.) in its  possession
relating to the other or to its business and affairs.

          (b) Except as otherwise required by law or agreed to in writing,  each
party shall, and shall cause each of its respective  subsidiaries to, retain all
information  relating to the other party's  business in accordance with the past
practice of such party. Notwithstanding the foregoing, except as provided in the
Tax  Sharing  Agreement,  any party may  destroy  or  otherwise  dispose  of any
information at any time,  providing that, prior to such destruction or disposal,
(a) such party shall  provide no less than 90 days prior  written  notice to the
other party, specifying the information proposed to be destroyed or disposed of,
and (b) if the  recipient of such notice shall  request in writing  prior to the
scheduled  date for such  destruction  or disposal  that any of the  information
proposed to be destroyed or disposed of be delivered to such  requesting  party,
the party proposing the  destruction or disposal shall promptly  arrange for the
delivery  of such of the  information  as was  requested  at the  expense of the
requesting party.

          Section 6.02. Access to Information.  From and after the Closing Date,
each of Olsten  and OHS shall  afford  the  other,  including  its  accountants,
counsel and other designated representatives, reasonable access (including using
reasonable  efforts to give access to persons or firms  possessing  information)
and  duplicating  rights during  normal  business  hours to all records,  books,
contacts,  instruments,  computer  data and other data and  information  in such
party's possession relating to the business and affairs of the other (other than
data and information subject to an attorney/client or other privilege),  insofar
as such access is  reasonably  required by the other  party  including,  without
limitation,  for  audit,  accounting  and  litigation  purposes,  as well as for
purposes of fulfilling disclosure and reporting obligations.

          Section 6.03.  Access to  Employees.  Each of Olsten and OHS shall use
reasonable  efforts to make available to the other,  upon written  request,  its
officers,  directors,  employees and agents as witnesses to the extent that such
persons may reasonably be required in connection with any legal,  administrative
or other  proceedings  arising  out of the  business  of the other  prior to the
Closing Date in which the requesting party may from time to time be involved.

          Section  6.04.  Reimbursement.  Each party  providing  information  or
witnesses  under Sections 6.02 or 6.03 to the other shall be entitled to receive
from the recipient, upon the presentation of invoices therefor,  payment for all
out-of-pocket costs and expenses as may be reasonably incurred in providing such
information or witnesses.

          Section 6.05.  Confidentiality.  Each party shall hold and shall cause
its directors, officers, employees, agents, consultants and advisors to hold, in
strict  confidence,  unless compelled to disclose by judicial or  administrative
process or, in the opinion of its  counsel,  by other  requirements  of law, all
confidential,  proprietary  or other  non-public  information  or trade  secrets
concerning  the other party  except to the extent that such  information  can be
shown to have been (a) in the public domain  through no fault of such party,  or
(b) later lawfully  acquired on a  non-confidential  basis from other sources by
the  party to which  it was  furnished  or (c)  developed  independently  by the
representatives  of such recipient.  Neither party shall release or disclose any
such information to any other person, except its auditors, attorneys,  financial
advisors, bankers and other consultants and advisors who shall be advised of and
comply with the provisions of this Section 6.05.

          Section  7.01.  Termination.  In the event  the  Merger  Agreement  is
terminated,  notwithstanding any provision hereof, Adecco shall automatically be
released as a party to this  Agreement and this  Agreement may be terminated and
the Split-Off  abandoned at any time prior to the  Effective  Time by and in the
sole  discretion of the Board of Directors of Olsten without the approval of OHS

an instrument in writing signed on behalf of Olsten, OHS and Adecco.

          Section  7.03.  Waiver of  Compliance;  Consents.  Rights  under  this
Agreement may be waived only by a written  agreement  signed by Olsten,  OHS and
Adecco.  Any  waiver or  failure  to insist  upon  strict  compliance  with such
obligation,  covenant,  agreement or condition shall not operate as a waiver of,
or estoppel  with respect to, any  subsequent  or other  failure.  Whenever this
Agreement requires or permits consent by or on behalf of any party hereto,  such
consent shall be given in writing.

          Section  7.04.  Expenses.  Except  as  specifically  provided  in this
Agreement  or in an  Ancillary  Agreement,  all costs and  expenses  incurred in

Agreement shall be paid by the party incurring the expense. The determination of
who has  incurred  an expense  shall be made by the Chief  Financial  Officer of
Olsten,  which determination shall be binding and final upon each of the parties
hereto and not subject to further review.

          Section 7.06.  Counterparts.  This Agreement may be executed in two or
more  counterparts  each of which shall be deemed an original,  but all of which
together shall constitute but one and the same Agreement.

          Section 7.07.  Governing Law. This Agreement  shall be governed by the
laws of the  State of New York  (regardless  of the laws  that  might  otherwise
govern  under  applicable  New York  principles  of  conflicts of law) as to all
matters, including but not limited to matters of validity, construction, effect,
performance   and  remedies.   Each  of  the  parties  hereto   irrevocably  and
unconditionally  consents to submit to the exclusive  jurisdiction of the courts
of the State of New York and of the  United  States of  America  located  in the





                                      -30-
<PAGE>
State of New York (the "New York Courts") for any  litigation  arising out of or
relating to this Agreement and the transactions  contemplated hereby (and agrees
not to commence any litigation  relating thereto except in such courts),  waives
any  objection  to the  laying of venue of any such  litigation  in the New York
Courts  and  agrees  not to  plead or claim  in any New  York  Court  that  such
litigation  brought therein has been brought in an inconvenient  forum.  Each of
the parties hereto hereby agrees to service of process in any litigation arising
out of or relating to this Agreement and the transactions contemplated hereby by
certified mail, return receipt requested,  postage prepaid, to it at its address
for notice specified in Section 7.05.

          Section  7.08.  Entire  Agreement.   This  Agreement,   including  the
schedules and exhibits hereto, together with the Ancillary Agreements,  embodies
the entire  agreement and  understanding of the parties hereto in respect to the
subject  matter  contained  herein  and  supersedes  all  prior  agreements  and
understandings   among  the  parties   with  respect   thereto.   There  are  no
representations,  promises, warranties,  covenants or undertakings by any party,
other than those expressly set forth or referred to herein.

          Section 7.09. Assignment; No Third Party Beneficiaries. This Agreement
and all of the provisions  hereof shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and permitted assigns, but
neither this Agreement nor any of the rights, interests or obligations hereunder
shall be assigned by any of the parties hereto without the prior written consent
of the other parties. Nothing contained in this Agreement, expressed or implied,
is  intended  to confer  any  benefits,  rights or  remedies  upon any person or
entity,  other than Olsten,  OHS and Adecco and, in accordance  with Article IV,
the Olsten Indemnitees and the OHS Indemnitees.

          Section  7.10.  Ancillary  Agreements.  If any of the  terms  of  this
Agreement are inconsistent  with the terms of an Ancillary  Agreement  regarding
the specific matters covered by such Ancillary Agreement, then the terms of such
Ancillary Agreement shall govern.

          Section 7.11. Tax Sharing Agreement. Other than as provided in Section
4.11,  Section 5.05 and clause (iv) of the definition of OHS  Liabilities,  this
Agreement  shall not govern any Tax,  and any and all claims,  losses,  damages,
demands,  costs, expenses,  liabilities,  refunds,  deductions,  write-offs,  or
benefits  relating  to Taxes  shall be  exclusively  governed by the Tax Sharing
Agreement.

          Section 7.12.  Further  Assurances  and  Consents.  In addition to the
actions  specifically  provided  for  elsewhere in this  Agreement,  each of the
parties hereto will use its  reasonable  best efforts to (i) execute and deliver
such further  instruments and documents and take such other actions as any other
party  may  reasonably  request  in order to  effectuate  the  purposes  of this
Agreement and to carry out the terms hereof and (ii) take, or cause to be taken,
all actions, and to do, or cause to be done, all things,  reasonably  necessary,
proper or  advisable  under  applicable  laws,  regulations  and  agreements  or
otherwise to consummate and make effective the transactions contemplated by this
Agreement, including, without limitation, using its reasonable efforts to obtain
any consents and approvals and to make any filings and applications necessary or
desirable  in  order  to  consummate  the  transactions   contemplated  by  this
Agreement;  provided  that  no  party  hereto  shall  be  obligated  to pay  any





                                      -31-
<PAGE>
consideration therefor (except for filing fees and other similar charges) to any
third party from whom such  consents,  approvals and amendments are requested or
to take any action or omit to take any  action if the taking of or the  omission
to take  such  action  would  be  unreasonably  burdensome  to the  party or its
business.  In connection with the  consummation of the transaction  contemplated
hereby,  the  persons  listed  on  Schedule  10  are  designated  to  act as the
"Transition Team" and are authorized to act on behalf of Adecco,  Olsten and OHS
in taking any action  necessary to consummate the Split-Off.  The persons listed
on Schedule 10 who are Adecco employees are authorized to deliver the consent of
Adecco if such consent is required by the terms of this Agreement.

          Section  7.13.  Exhibits and  Schedules.  The  exhibits and  schedules
hereto shall be construed  with and as an integral part of this Agreement to the
same extent as if the same had been set forth verbatim herein.

          Section 7.14.  Legal  Enforceability.  Any provision of this Agreement
which is prohibited  or  unenforceable  in any  jurisdiction  shall,  as to such
jurisdiction,   be   ineffective   to  the   extent  of  such   prohibition   or
unenforceability  without invalidating the remaining provisions hereof. Any such
prohibition  or  unenforceability  in any  jurisdiction  shall not invalidate or
render unenforceable such provision in any other jurisdiction. Without prejudice
to any rights or remedies  otherwise  available to any party hereto,  each party
hereto  acknowledges  that from and after the Effective Time damages would be an
inadequate  remedy for any breach of the provisions of this Agreement and agrees
that the obligations of the parties hereunder shall be specifically enforceable.

          Section 7.15. Dispute Resolution. (a) Except as otherwise set forth in
Sections 2.06 and 2.08(c),  resolution of any and all disputes arising after the
Effective Time from or in connection with this Agreement or any of the Ancillary
Agreements,  whether based on contract,  tort, statute or otherwise,  including,
but not limited to, disputes over  arbitrability and disputes in connection with
indemnification for claims by third parties (collectively,  "Disputes") shall be
exclusively  governed by and settled in accordance  with the  provisions of this
Section 7.15;  provided,  however,  that nothing contained herein shall preclude
either party from seeking or obtaining (a) injunctive relief or (b) equitable or
other judicial relief to enforce the provisions hereof or to preserve the status
quo pending resolution of Disputes hereunder.

          (b)  Any  party  hereto  (each a  "Party")  may  commence  proceedings
hereunder  by  delivering  a  written  notice  to the other  Party  providing  a
reasonable description of the Dispute to the other (the "Demand").

          (c)  Promptly  following a Demand,  the  Dispute  shall be referred to
representatives  of the parties for decision,  each party being represented by a
senior executive officer who has no direct  operational  responsibility  for the
matters   contemplated   by  this   Agreement   (the   "Representatives").   The
Representatives  shall  promptly  meet in a good  faith  effort to  resolve  the
dispute.  If the Representatives do not agree upon a decision within 30 calendar
days after reference of the matter to them, each of Olsten and OHS shall be free
to exercise the remedies available to them under Section 7.15(d).

          (d) The parties  hereby  agree to submit all  Disputes not resolved by
negotiation  pursuant to Section 7.15(c) to arbitration  under the terms hereof,
which arbitration shall be final, conclusive and binding upon the parties, their
successors and assigns.  The arbitration shall be conducted in New York by three
arbitrators  (the "Panel")  acting by majority vote selected by agreement of the
Parties  not later than 10 days  after the  failure  of the  Representatives  to
resolve the dispute as set forth in Section  7.15(c) or, failing such agreement,
by three arbitrators  appointed pursuant to the Commercial  Arbitration Rules of
the  American  Arbitration  Association,  as amended from time to time (the "AAA
Rules").  If an  arbitrator  so  selected  becomes  unable to serve,  his or her
successors shall be similarly  selected or appointed.  The arbitration  shall be
conducted pursuant to the United States Arbitration Act, 9 U.S.C. ss. 1, et seq.
and such  procedures as the Parties may agree,  or, in the absence of or failing
such agreement,  pursuant to the AAA Rules.  Notwithstanding  the foregoing,  in
connection with such  arbitration:  (a) each Party shall have the right to audit
the books and  records  of the other  Party that are  reasonably  related to the
Dispute; (b) each Party shall provide to the other, reasonably in advance of any
hearing,  copies of all  documents  which a Party  intends  to  present  in such
hearing; (c) each party shall be allowed to conduct reasonable discovery through
written  requests  for  information,  document  requests,  requests to admit and
depositions, the nature and extent of which discovery shall be determined by the
Panel,  taking into  account the needs of the  Parties and the  desirability  of
making discovery expeditious and cost effective. All hearings shall be conducted
on an expedited  schedule,  and all proceedings  shall be  confidential.  Either
party may at its expense make a  stenographic  record  thereof.  The Panel shall
make a final  award not later than 30 days after the  conclusion  of the hearing
and receipt of any  post-hearing  submissions  requested by the Panel. The award
shall be in writing and shall specify the factual and legal basis for the award.
The fees and expenses of the arbitrators  shall be shared equally by the Parties
and  advanced  by them  from  time to time  as  required;  provided  that at the
conclusion  of the  arbitration,  the Panel shall  allocate  costs and  expenses
(including  the costs of the  arbitration  previously  advanced and the fees and

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

           EMPLOYMENT  AGREEMENT,  dated as of February 10, 1999, by and between
OLSTEN  CORPORATION,  a  Delaware  corporation  (the  "Company"),  and EDWARD A.
BLECHSCHMIDT ("Executive").


                              W I T N E S S E T H:
                              -------------------

           WHEREAS,  Executive has served the Company as its President and Chief
Operating Officer since October 19, 1998; and

           WHEREAS,  the Company  desires that Executive  assume the position of
Chief Executive Officer and Executive is willing to accept such appointment;

           WHEREAS,  the Company and  Executive  wish to enter into an agreement
embodying  the  terms  of  his  employment  as  Chief  Executive   Officer  (the
"Agreement"); and

           NOW,  THEREFORE,  in  consideration  of the mutual  covenants  herein
contained, the Company and Executive hereby agree as follows:

1. Employment.  Upon the terms and subject to the  conditions of this Agreement,
the Company hereby agrees to continue to employ  Executive and Executive  hereby
agrees to continue his  employment by the Company until February 9, 2002. At the
expiration of the original  term or any extended  term,  Executive's  employment
hereunder shall be automatically  extended,  upon the same terms and conditions,
for successive  periods of two years each, unless either party, at least 90 days
prior to the  expiration of the original term or any extended  term,  shall give
written  notice  to the other of its  intention  not to renew  such  employment.
Notwithstanding  the foregoing,  the term of this Agreement  shall expire on the
last day of the month in which Executive attains age 65. The period during which
Executive  is  employed  pursuant to this  Agreement,  including  any  extension
thereof  in  accordance  with  this  Section  1,  shall  be  referred  to as the
"Employment Period."

2. Position and Duties.  During the Employment Period,  Executive shall serve as
Chief Executive Officer of the Company and shall be nominated for election,  and
if so elected,  shall serve as a member of the Board of Directors of the Company
(the  "Board").  In addition,  Executive  shall serve in such other  position or
positions with the Company and its subsidiaries  commensurate  with his position
and  experience  as the  Board  shall  from  time to time  specify.  During  the
Employment  Period,  Executive  shall  have  the  duties,  responsibilities  and
obligations  customarily  assigned to individuals serving as the chief executive
officer of a New York Stock  Exchange  listed  company,  and such other  duties,
responsibilities  and  obligations as the Board shall from time to time specify.
Executive shall devote his full time to the services  required of him hereunder,
except for  vacation  time and  reasonable  periods of absence due to  sickness,
personal injury or other disability, and shall use his best efforts,  judgement,
skill and energy to perform such services in a manner  consonant with the duties
of his position  and to improve and advance the  business  and  interests of the
Company and its subsidiaries. Nothing contained in this Section 2 shall preclude
Executive   from  (i)  serving  on  the  board  of  directors  of  any  business





<PAGE>
corporation,  unless such  service  would be contrary to  applicable  law,  (ii)
serving  on  the  board  of,  or  working  for,  any   charitable  or  community
organization or (iii) pursuing his personal financial and legal affairs, so long
as such  activities,  individually  or  collectively,  do not interfere with the
performance of Executive's  duties hereunder or violate any of the provisions of
Section 6 hereof.

3. Compensation.

      (a) Base  Salary.  During the  Employment  Period,  the Company  shall pay
Executive a base salary at the annual  rate of  $750,000  per annum.  The annual
base salary payable under this section shall be reduced,  however, to the extent
Executive  elects  to  defer  such  salary  under  the  terms  of  any  deferred
compensation  or savings plan or  arrangement  maintained or  established by the
Company or any other  arrangement  acceptable to the Company.  The Board (or the
appropriate  committee  of the Board) shall  annually  review  Executive's  base
salary  in light of  competitive  practices,  the  base  salaries  paid to other
executive  officers of the  Company and the  performance  of  Executive  and the
Company,  and may, in its discretion,  increase such base salary by an amount it
determines to be  appropriate.  Any such increase  shall not reduce or limit any
other obligation of the Company hereunder. Executive's base salary (as set forth
above or as may be  increased  from time to time) shall not be  reduced,  except
that  Executive's  base  salary  may be  reduced  in  proportion  to  comparable
reductions in the base salaries of the Company's  other  executive  officers (as
determined for purposes of Section 16(b) of the Securities Exchange Act of 1934,
as amended).  Executive's  annual base salary  payable  hereunder,  as it may be
increased  from time to time and without  reduction for any amounts  deferred as
described  above,  is referred to herein as "Base Salary." The Company shall pay
Executive the portion of his Base Salary not deferred not less  frequently  than
in equal bi-weekly installments.

      (b) Annual Bonus.  For each  calendar  year ending  during the  Employment
Period, Executive shall have the opportunity to receive an annual bonus ("Annual
Target  Bonus  Opportunity"),  based on the  achievement  of  target  levels  of
performance,  equal  to 80% of his  Base  Salary;  provided  that,  so  long  as
Executive is employed on the last day of each such  calendar  year,  in no event
shall the annual bonus payable to Executive  for each of the Company's  1999 and
2000  fiscal  years be less  than an  amount  equal to 50% of  Executive's  Base
Salary, regardless of whether any applicable performance criteria have been met.
Depending  on actual  results as  measured  against the  performance  objectives
established,  Executive's  actual bonus  payment may range from (i) a low of (A)
50% of  Executive's  Base Salary  with  respect to the  Company's  1999 and 2000
fiscal years and (B) zero for subsequent  fiscal years to (ii) a maximum of 120%
of  Executive's  Base Salary for each full  fiscal  year  during the  Employment
Period.  Subject to the guaranteed minimum set forth above, the actual bonus, if
any,  payable for any such year shall be determined in accordance with the terms
of the Company's  Executive  Officers' Bonus Plan (the "Annual Plan") based upon
the  performance  of the Company  and/or  Executive  against  target  objectives
established  under such Annual Plan.  The  determination  of whether and to what
extent the requisite  performance  objectives have been met shall be made by the
committee  responsible for  administering  the Annual Plan, whose  determination
shall be final. Subject to Executive's election to defer all or a portion of any
annual  bonus  payable   hereunder   pursuant  to  the  terms  of  any  deferred
compensation  or savings plan or  arrangement  maintained or  established by the
Company,  any annual  bonus  payable  under this  Section  3(b) shall be paid to




                                       2
<PAGE>
Executive in  accordance  with the terms of the Annual Plan,  provided,  however
that,  regardless  of the terms of such Annual  Plan,  Executive  shall have the
right to defer  payment of up to that portion of his annual  bonus  which,  when
coupled  with any  portion  of his Base  Salary  deferred  for the same  year of
service,  does not exceed 50% (or such greater  percentage  as the Company shall
permit) of the sum of his Base Salary and his annual bonus,  provided,  however,
that, any portion of  Executive's  annual bonus which would not be deductible to
the Company pursuant to the provisions of Section 162(m) of the Internal Revenue
Code of 1986, as amended (the "Code"), shall be deferred. Unless Executive shall
otherwise  elect a  different  payment  date or dates or a  different  number of
payments,  any portion of  Executive's  annual bonus and/or Base Salary which is
deferred in accordance  with this Section 3 (whether at Executive's  election or
by reason of Section  162(m)) shall be payable to Executive in a single lump sum
as soon as practicable following  termination of Executive's  employment for any
reason and shall be credited with interest,  on a compounded  basis, on the last
day of each  calendar  quarter,  at 1% above the prime rate (as  reported in The
Wall Street  Journal,  Eastern  Edition),  as in effect on the first day of each
such  calendar  quarter.  Any  election by Executive to change the timing of the
distribution  of the deferred  amounts  and/or the number of payments to be made
shall be made in writing in a calendar  year prior to the date  payment is to be
made,  and shall only be effective  if Executive  completes at least six months'
additional  service as an employee following the date any such election is filed
with the Secretary of the Company.

      (c)  Stock  Option  Grant.  Effective  as of the  date of this  Agreement,
Executive  has been awarded a stock option (the  "Option") in respect of 150,000
shares of the  Company's  common  stock,  par value $.10 per share (the  "Common
Stock").  Subject to the provisions of Section 5, the Option shall become vested
and exercisable in five annual installments of 30,000 shares each on each of the
first five  anniversaries  of the date of grant,  subject to acceleration of the
exercisability thereof in certain circumstances (including,  without limitation,
a Change of Control as defined in the 1994 Stock  Incentive  Plan ("SOP")) to be
set  forth  in the  option  agreement  related  to such  grant  and  subject  to
forfeiture,  in whole or in part,  in the event of  Executive's  termination  of
employment  prior to the Option  becoming  exercisable in full. The Option shall
have a ten year term, subject to earlier termination in the event of Executive's
termination of employment.  Except as otherwise provided above, the terms of the
Option shall be as determined under the SOP and as set forth in a separate stock
option agreement.

      (d)  Performance Based-Stock Award.

           (i) Fifteen Dollar  Performance  Hurdle. If, at any date on or before
December 31, 2000,  the trading price of a share of Common Stock reported on any
national  securities  exchange  on which the  Common  Stock is listed  for trade
equals or  exceeds  $15 or the  Company's  shareholders  receive  for a share of
Common Stock cash and/or  property in any  transaction  constituting a Change of
Control,  as defined  below (the  "Change of Control  Consideration"),  having a
combined value at any time on the date of such  transaction at least to equal to
$15 (with the value of any property which does not have a readily  ascertainable
fair market value to be conclusively determined by the Compensation Committee of
the Board, as constituted  immediately prior to any such transaction),  then, as
of such date (the "Stock Grant Date"),  Executive shall be awarded 60,467 shares
of Common Stock (the  "Restricted  Shares") that are subject to forfeiture until
vested, in whole or in part, as hereinafter  provided.  Certificates  evidencing




                                       3
<PAGE>
the Restricted  Shares shall be issued to Executive as soon as practicable after
the Stock Grant Date,  but shall be legended in such manner as the Company shall
determine  to reflect  the fact that such  Restricted  Shares are not vested and
have not been registered  under the Securities Act of 1933, as amended.  Subject
to the  restrictions  imposed  hereby,  Executive  shall  have all  rights  of a
shareholder,  including the right to vote the  Restricted  Shares and to receive
any amounts paid as a dividend thereon,  from and after the Stock Grant Date and
unless  and until  such  Restricted  Shares  are  forfeited  by  Executive.  The
Restricted Shares will vest in three  installments of 20,155,  20,156 and 20,156
shares on each of the first,  second and third  anniversaries of the Stock Grant
Date,  provided  that  Executive is still in the  Company's  employ on each such
anniversary date. Any Restricted Shares  outstanding at such time will also vest
upon the occurrence of a Change of Control (as defined in Section 5(d) hereof).

           The Restricted  Shares shall not be transferrable by Executive to any
person (other than the Company) prior to the time such Restricted Shares vest in
accordance   herewith.   Except  as  otherwise  expressly  provided  herein,  if
Executive's  employment  terminates for any reason,  any Restricted  Shares that
have not otherwise  become vested in accordance  with this Section 3(d)(i) shall
be forfeited and returned to the Company  without any payment  therefor.  In the
event that Executive's employment terminates due to his death or Disability,  or
in a Termination Without Cause or a Termination for Good Reason,

      (i)  on or after the Stock  Grant  Date and prior to fully  vesting in any
           Restricted Shares awarded  hereunder,  Executive will be deemed fully
           vested  in  all  of  such  Restricted  Shares  on the  date  of  such
           termination of employment or

      (ii) prior  to a Stock  Grant  Date and a Stock  Grant  Date  occurs on or
           before December 31, 2000 and

           (A)  on or before  the three (3)  month  anniversary  of  Executive's
                termination of employment,  Executive  shall be treated as fully
                and automatically  vested in all of the Restricted Shares on the
                Stock Grant Date, or

           (B)  after the three month anniversary of Executive's  termination of
                employment,  Executive shall be treated as automatically  vested
                in one-half of the Restricted Shares on the Stock Grant Date.

           For purposes of subclauses (A) and (B) above,  a monthly  anniversary
           date shall occur on the same date in a following month as the date of
           termination or, if there is no same date in any subsequent  month, on
           the last day of such following month (e.g.,  if the termination  date
           is December 31, the relevant  anniversary  dates shall be January 31,
           February 28 and March 31).

If a share of Common Stock does not trade at a value (or the shareholders do not
receive Change of Control  Consideration)  at least equal to $15 per share on or
before December 31, 2000, no Restricted Shares shall be awarded to Executive.

           (ii) Twenty-Five  Dollar  Performance  Hurdle.  If, at any time on or
before  December 31, 2001, the trading price of a share of Common Stock reported
on any  national  securities  exchange  on which the Common  Stock is listed for
trade  equals or exceeds $25 or the  Company's  shareholders  receive  Change of
Control  Consideration  having a combined  value at any time on the date of such
transaction  at least to equal to $25 (with the value of any property which does
not have a readily ascertainable fair market value to be conclusively determined
by the Compensation Committee of the Board, as constituted  immediately prior to
any such  transaction),  then,  as of such date (the  "Supplemental  Stock Grant
Date"),   Executive  shall  be  awarded  76,280  shares  of  Common  Stock  (the
"Supplemental  Restricted  Shares") that are subject to forfeiture until vested,
in  whole or in part,  as  hereinafter  provided.  Certificates  evidencing  the
Supplemental  Restricted  Shares  shall  be  issued  to  Executive  as  soon  as
practicable  after the  Supplemental  Stock Grant Date, but shall be legended in
such  manner  as the  Company  shall  determine  to  reflect  the fact that such
Supplemental Restricted Shares are not vested and have not been registered under
the  Securities  Act of 1933, as amended.  Subject to the  restrictions  imposed
hereby, Executive shall have all rights of a shareholder, including the right to
vote the  Supplemental  Restricted  Shares and to receive any amounts  paid as a
dividend  thereon,  from and after the Supplemental  Stock Grant Date and unless
and until such Supplemental  Restricted  Shares are forfeited by Executive.  The
Supplemental Restricted Shares will vest in three installments of 25,426, 25,427
and 25,427 shares on each of the first,  second and third  anniversaries  of the
Supplemental Stock Grant Date, provided that Executive is still in the Company's
employ on each such anniversary  date. The Supplemental  Restricted  Shares will
also vest upon the occurrence of a Change of Control (as defined in Section 5(d)
hereof).

           The  Supplemental  Restricted  Shares shall not be  transferrable  by
Executive to any person (other than the Company) prior to the time at which such
Supplemental Restricted Shares vest in accordance herewith.  Except as otherwise
expressly provided herein, if Executive's  employment terminates for any reason,
any  Supplemental  Restricted  Shares that have not  otherwise  become vested in
accordance  with this Section  3(d)(ii)  shall be forfeited  and returned to the
Company without any payment therefor.  In the event that Executive's  employment
terminates due to his death or Disability,  or in a Termination Without Cause or
a Termination for Good Reason,

      (i)  on or after  the  Supplemental  Stock  Grant  Date and prior to fully
           vesting in any  Supplemental  Restricted  Shares  awarded  hereunder,
           Executive  will be deemed  fully  vested in all of such  Supplemental
           Restricted Shares on the date of such termination of employment or

      (ii) prior to a  Supplemental  Stock Grant Date and a  Supplemental  Stock
           Grant Date occurs on or before December 31, 2001 and

           (A)  on or before  the three (3)  month  anniversary  of  Executive's
                termination of employment,  Executive  shall be treated as fully
                and automatically  vested in all of the Supplemental  Restricted
                Shares on the Supplemental Stock Grant Date, or

           (B)  after the three month anniversary of Executive's  termination of
                employment,  Executive shall be treated as automatically  vested
                in  one-half  of  the  Supplemental  Restricted  Shares  on  the
                Supplemental Stock Grant Date.




                                       5
<PAGE>
           For purposes of subclauses (A) and (B) above,  a monthly  anniversary
           date shall occur on the same date in a following month as the date of
           termination or, if there is no same date in any subsequent  month, on
           the last day of such following month (e.g.,  if the termination  date
           is December 31, the relevant  anniversary  dates shall be January 31,
           February 28 and March 31).

If a share of Common Stock does not trade at a value (or the shareholders do not
receive Change of Control  Consideration)  at least equal to $25 per share on or
before December 31, 2001, no Supplemental  Restricted Shares shall be awarded to
Executive.

           (iii)In the event of a stock split  (including a reverse stock split)
with  respect to, or a stock  dividend on, the  Company's  Common Stock or other
recapitalization  or similar  transaction  affecting  the  capital  stock of the
Company,  the  appropriate  committee  of the Board  shall  make an  appropriate
adjustment to the stock price  targets and the number of  Restricted  Shares and
Supplemental Restricted Shares referred to in subclauses (i) and (ii) above.

           (iv) Executive shall be entitled to elect to pay the amount of income
and employment taxes required to be withheld in respect of any Restricted Shares
or  Supplemental  Restricted  Shares  that  become  vested  from such  Shares by
directing the Company in writing to withhold from each  installment  thereof the
least  number  of shares  as shall be  necessary  to  satisfy  such  withholding
obligations  and to distribute to Executive (or, in the event of his death,  his
estate)  the net number of such  Restricted  Shares or  Supplemental  Restricted
Shares as shall have become vested.

           (v) Upon the vesting of any  Restricted  Shares  and/or  Supplemental
Restricted   Shares,   Executive  shall   surrender  the  legended   certificate
representing such Shares and the Company shall issue a new certificate,  without
legend,  reflecting the number of Shares that have become vested (but reduced by
the  number,  if any,  of shares  applied  to  satisfy  Executive's  withholding
obligations  in  accordance  with  subsection  (iii)  above) and a new  legended
certificate  representing the remaining number of unvested  Restricted Shares or
Supplemental Restricted Shares.

           (vi) Prior  Performance  Award.  The  performance-based  stock  award
granted  to  Executive  pursuant  to Section 5 of the  Letter  Agreement  by and
between  Executive and the Company,  dated as of September 11, 1998 (the "Letter
Agreement"), is hereby superseded in its entirety.

4. Benefits, Perquisites and Expenses.

      (a) Benefits. During the Employment Period, Executive shall be eligible to
participate  in (i) each welfare  benefit plan  sponsored or  maintained  by the
Company,  including,  without  limitation,  each  group  life,  hospitalization,
medical,  dental,  health,  accident or disability  insurance or similar plan or
program of the Company, and (ii) each pension, retirement, deferred compensation
or savings plan  sponsored or maintained by the Company,  in each case,  whether
now existing or established hereafter,  to the extent that Executive is eligible
to  participate  in any such plan  under  the  generally  applicable  provisions
thereof.  Nothing in this Section 4(a) shall limit the Company's  right to amend
or terminate any such plan in accordance with the procedures set forth therein.

      (b) SERP Supplement.  Effective as of the date hereof,  Executive shall be
credited,  under the terms of the Company's Supplemental Retirement Plan for Key
Executives  Designated  by the Company  ("SERP"),  with 10 years of service,  in
addition  to  any  other  service  that  may be  credited  thereunder  based  on
Executive's  actual  employment  with the Company.  In  determining  the maximum
benefit  payable under the SERP in the case of Executive's  retirement  prior to
age 62, the  fraction set forth in Section 5.5 of the SERP shall be deemed to be
one.  Additionally,  if Executive  completes 10 years of actual service with the
Company  prior  to  his  termination  of  employment  or if  his  employment  is
terminated prior to completing 10 years of actual service in a termination which
is a Termination  Without Cause or a Termination  for Good Reason (in each case,
as defined in Section 5), then  notwithstanding the provisions of Section 5.2 of
the SERP,  the reduction for early  commencement  of his accrued  benefits under
shall be 3% per annum.  Notwithstanding the foregoing, if Executive's employment
with the Company is terminated  by the Company in a Termination  for Cause or by
Executive  other than in a  Termination  for Good Reason  prior to February  10,
2004, then,  solely for purposes of determining the extent to which Executive is
vested in his accrued  benefit  pursuant to Section 5.7 of the SERP (but not for
purposes of determining the amount of such accrued benefit),  Executive shall be
deemed to have only been credited with 5 years of additional  service under this
Section 4(b).  The following  table  illustrates  the extent to which  Executive
shall be vested if Executive's  employment with the Company is terminated by the
Company in a Termination  for Cause or by Executive  other than in a Termination
for Good Reason prior to February 10, 2004:

 |----------------------------------------------------------------------------|
 |     Date Employment Terminates     |          Percent Vested               |
 |------------------------------------|---------------------------------------|
 | Before February 10, 2000           |      At least 50% (based on           |
 |                                    |   5 years of additional service)      |
 |------------------------------------|------------- -------------------------|
 | On or after February 10, 2000 and  |      At least 60% (based on           |
 | before February 10, 2001           |     1 year of actual service,         |
 |                                    |  plus 5 years of additional service)  |
 |------------------------------------|------------- -------------------------|
 | On or after February 10, 2001 and  |      At least 70% (based on           |
 | before February 10, 2002           |    2 years of actual service,         |
 |                                    |  plus 5 years of additional service)  |
 |------------------------------------|------------- -------------------------|
 | On or after February 10, 2002 and  |      At least 80% (based on           |
 | before February 10, 2003           |    3 years of actual service,         |
 |                                    |  plus 5 years of additional service)  |
 |------------------------------------|------------- -------------------------|
 | On or after February 10, 2003 and  |      At least 90% (based on           |
 | before February 10, 2004           |    4 years of actual service,         |
 |                                    |  plus 5 years of additional service)  |
 |------------------------------------|------------- -------------------------|
 | On or after February 10, 2004      |               100%                    |
 |----------------------------------------------------------------------------|

For purposes of determining  Executive's  benefit under the SERP with respect to
any  calculation  of  Executive's  benefits to be made prior to January 1, 2004,
Executive's Final Average Earnings  determined using his actual compensation for
any full calendar year of service  completed after 1998 and deeming Executive to
have been paid an amount  equal to 180% of his Base  Salary  for that  number of
additional  years  equal to the  remainder  of (i) five (5) and (ii) the  actual
number of full years of service he has completed since 1998.

with a third party relocation service selected by the Company.

Company.

      (e)  Indemnification.  During the  Employment  Period,  the Company  shall

or cause of action arising from or out of Executive's performance as an officer,
director or employee of the Company or any of its  subsidiaries  or in any other
capacity,  including any fiduciary  capacity,  in which Executive  serves at the
request of the Company to the maximum extent permitted by applicable law and the

      (d) Definitions.  For purposes of Sections 5 and 6, capitalized terms have
the following meanings:

          "Additional Benefits" means, if Executive's  employment terminates due
to death or in a  Termination  due to  Disability,  the  benefits  described  in
subclause  (i)  below,  or if the  Executive's  employment  is  terminated  in a
Termination  Without  Cause or a  Termination  for  Good  Reason,  the  benefits
described in subclauses (i) and (ii):

           (i)  Executive  (or,  in the event of  Executive's  death  during the
                90-day   period   following   such   termination,    Executive's
                beneficiary  or estate) shall have the right,  during the 90-day
                period following  Executive's  termination of employment for any
                reason  other  than  death  or  the  270-day  period   following
                Executive's  termination of employment due to death, to exercise
                any  outstanding  options to purchase  shares of Common Stock of
                the Company  that have become  exercisable  prior to the date of
                such  termination  and that would  have  become  exercisable  by
                Executive in accordance with the applicable option agreement and
                the applicable  equity  incentive  plan of the Company  assuming
                that  Executive  continued  in the employ of the  Company for an
                additional  18  months  after  the  date of his  termination  of
                employment;

           (ii) Executive (and, to the extent  applicable,  his dependents) will
                be entitled to continue  participation  in all of the  Company's
                medical,  dental and vision  care  plans  (the  "Health  Benefit
                Plans"),   until  the  18-month   anniversary   of   Executive's
                termination   of   employment;    provided   that    Executive's
                participation  in the Company's Health Benefit Plans shall cease
                on  any  earlier  date  that  Executive   becomes  eligible  for
                comparable  benefits  from a  subsequent  employer.  Executive's
                participation  in the Health  Benefit  Plans will be on the same
                terms  and  conditions  (including,   without  limitation,   any
                contributions that would have been required from Executive) that
                would have applied had Executive continued to be employed by the
                Company.  To the extent  any such  benefits  cannot be  provided
                under the terms of the applicable plan,  policy or program,  the
                Company shall provide a comparable benefit under another plan or
                from the Company's general assets.

                provided that, in the event that any severance  payment is to be

                in  subclause  (ii)  shall be  deemed to be the  greater  of the
                amount determined as calculated above or the amount described in

           "Termination for Cause" means a termination of Executive's employment
by the Company due to (i) Executive's  conviction of a felony,  (ii) Executive's
willful and  continued  failure to perform the  material  duties of his position

termination  without regard to the performance by Executive of further  services
or the resolution of a contingency.

      (e) Full Discharge of Company Obligations. Except as expressly provided in
the last  sentence  of this  Section  5(e),  the  amounts  payable to  Executive
pursuant to this Section 5 following  termination of his  employment  (including
amounts  payable with respect to Vested  Benefits) shall be in full and complete
satisfaction of Executive's  rights under this Agreement and any other claims he
may have in respect of his employment by the Company or any of its subsidiaries.
Such amounts  shall  constitute  liquidated  damages with respect to any and all
such  rights and claims  and,  upon  Executive's  receipt of such  amounts,  the
Company shall be released and discharged from any and all liability to Executive
in connection  with this Agreement or otherwise in connection  with  Executive's
employment with the Company and its  subsidiaries.  If requested by the Company,
Executive shall execute a release  following  termination of his employment,  in
form and substance  satisfactory to the Company (but not  inconsistent  with the
terms of this  Agreement),  as a prior  condition to the receipt of the benefits
payable  pursuant  to this  Section  5.  Nothing in this  Section  5(e) shall be
construed to release the Company from its commitment to indemnify  Executive and
hold Executive  harmless from and against any claim,  loss or cause of action as
described in Section 4(e).

      (f)  Certain Further Payments by the Company.

           (i) In the event that any amount or benefit  paid or  distributed  to
the Executive  pursuant to this  Agreement,  taken  together with any amounts or
benefits  otherwise  paid or  distributed to the Executive by the Company or any
affiliated company (collectively, the "Covered Payments"), are or become subject
to the tax (the "Excise  Tax")  imposed  under  Section 4999 of the Code, or any
similar  tax that  may  hereafter  be  imposed,  the  Company  shall  pay to the
Executive at the time  specified in Section  5(f)(v) below an additional  amount
(the "Tax  Reimbursement  Payment")  such that the net  amount  retained  by the
Executive with respect to such Covered  Payments,  after deduction of any Excise
Tax on the  Covered  Payments  and  any  Federal,  state  and  local  income  or
employment tax and Excise Tax on the Tax  Reimbursement  Payment provided for by
this Section 5(f), but before  deduction for any Federal,  state or local income
or employment tax  withholding on such Covered  Payments,  shall be equal to the
amount of the Covered Payments.

           (ii) For purposes of determining  whether any of the Covered Payments
will be subject to the Excise Tax and the amount of such Excise Tax,











                                       11
<PAGE>
           (A)  such Covered  Payments will be treated as  "parachute  payments"
                within  the  meaning  of  Section  280G  of the  Code,  and  all
                "parachute  payments" in excess of the "base amount" (as defined
                under  Section  280G(b)(3)  of the  Code)  shall be  treated  as
                subject  to the  Excise  Tax,  unless,  and except to the extent
                that, in the good faith  judgment of the  Company's  independent
                certified  public  accountants  appointed prior to the Change of
                Control  or  tax  counsel  selected  by  such  Accountants  (the
                "Accountants"),  the Company has a reasonable  basis to conclude
                that such  Covered  Payments (in whole or in part) either do not
                constitute   "parachute   payments"  or   represent   reasonable
                compensation for personal services actually rendered (within the
                meaning of Section  280G(b)(4)(B)  of the Code) in excess of the
                "base  amount," or such  "parachute  payments" are otherwise not
                subject to such Excise Tax, and

           (B)  the value of any non-cash  benefits or any  deferred  payment or
                benefit  shall be determined  by the  Accountants  in accordance
                with the principles of Section 280G of the Code.

           (iii)For  purposes of determining the amount of the Tax Reimbursement
Payment, the Executive shall be deemed to pay:

           (A)  Federal income taxes at the highest applicable  marginal rate of
                Federal  income  taxation for the calendar year in which the Tax
                Reimbursement Payment is to be made, and

           (B)  any  applicable  state and  local  income  taxes at the  highest
                applicable  marginal  rate of taxation for the calendar  year in
                which the Tax  Reimbursement  Payment is to be made,  net of the
                maximum  reduction  in  Federal  income  taxes  which  could  be
                obtained from the deduction of such state or local taxes if paid
                in such year.

           (iv) In the event that the Excise Tax is  subsequently  determined by
the Accountants or pursuant to any proceeding or negotiations  with the Internal
Revenue  Service to be less than the  amount  taken into  account  hereunder  in
calculating the Tax Reimbursement Payment made, the Executive shall repay to the
Company,  at the time that the  amount of such  reduction  in the  Excise Tax is
finally  determined,  the portion of such prior Tax  Reimbursement  Payment that
would  not have been  paid if such  Excise  Tax had been  applied  in  initially
calculating such Tax Reimbursement  Payment, plus interest on the amount of such
repayment  at  the  rate  provided  in  Section   1274(b)(2)(B)   of  the  Code.
Notwithstanding the foregoing, in the event any portion of the Tax Reimbursement
Payment to be refunded to the  Company  has been paid to any  Federal,  state or
local tax authority, repayment thereof shall not be required until actual refund
or credit of such portion has been made to the Executive,  and interest  payable
to the Company shall not exceed  interest  received or credited to the Executive
by such tax authority for the period it held such portion. The Executive and the
Company  shall  mutually  agree upon the course of action to be pursued (and the
method of allocating the expenses  thereof) if the Executive's  good faith claim
for refund or credit is denied.







                                       12
<PAGE>
           In  the  event  that  the  Excise  Tax  is  later  determined  by the
Accountants  or pursuant to any  proceeding  or  negotiations  with the Internal
Revenue  Service to exceed the amount taken into  account  hereunder at the time
the Tax Reimbursement Payment is made (including,  but not limited to, by reason
of any payment the existence or amount of which cannot be determined at the time
of the Tax  Reimbursement  Payment),  the Company shall make an  additional  Tax
Reimbursement  Payment in respect of such excess  (plus any  interest or penalty
payable  with respect to such excess) at the time that the amount of such excess
is finally determined.

           (v) The Tax  Reimbursement  Payment (or portion thereof) provided for
in  Section  5(f)(i)  above  shall be paid to the  Executive  not later  than 10
business days following the payment of the Covered Payments;  provided, however,
that if the amount of such Tax Reimbursement Payment (or portion thereof) cannot
be finally determined on or before the date on which payment is due, the Company
shall pay to the Executive by such date an amount estimated in good faith by the
Accountants to be the minimum amount of such Tax Reimbursement Payment and shall
pay the remainder of such Tax  Reimbursement  Payment (together with interest at
the rate  provided in Section  1274(b)(2)(B)  of the Code) as soon as the amount
thereof can be  determined,  but in no event  later than 45 calendar  days after
payment  of the  related  Covered  Payment.  In the event that the amount of the
estimated Tax Reimbursement  Payment exceeds the amount subsequently  determined
to have been due,  such  excess  shall  constitute  a loan by the Company to the
Executive, payable on the fifth business day after written demand by the Company
for  payment   (together   with   interest  at  the  rate  provided  in  Section
1274(b)(2)(B) of the Code).

6. Noncompetition and Confidentiality. By and in consideration of the salary and
benefits to be provided by the Company  hereunder,  including  particularly  the
severance arrangements set forth herein, Executive agrees that:

      (a)  Noncompetition.  Executive  acknowledges  that  the  Company  and its
subsidiaries  conduct  business  throughout the United  States,  the District of
Columbia,  Canada,  Mexico,  Latin  America and  Europe,  and that his duties to
Company relate to some or all of these  territories  and to some or all business
lines of the  Company.  During the  Employment  Period and during the nine month
period  following  any  termination  of  Executive's  employment,  other  than a
Termination Without Cause or a Termination for Good Reason,  Executive shall not
directly or indirectly: (i) perform or provide any services to any individual or
business  which is  engaged in the type of  business(es)  similar to the type of
business(es)  conducted by Company or any of its subsidiaries;  and/or (ii) own,
manage,  operate,  control,  be employed by, participate in, provide services or
financial  assistance  to, or be connected in any manner  with,  the  ownership,
management,  operation or control of any business which  directly  competes with
Company  or any of its  subsidiaries  or  engages  in the  type of  business(es)
principally  conducted  by the Company or any of its  subsidiaries,  except that
Executive may own for  investment  purposes up to 1% of the capital stock of any
such company whose stock is publicly traded.

      (b)  Confidentiality.  Except as may be required by the lawful  order of a
court or agency of competent  jurisdiction,  or applicable law, or except to the
extent that  Executive  has express  authorization  from the Company,  Executive
agrees to keep secret and confidential  indefinitely all non-public  information
(including,  without limitation,  information  regarding  litigation and pending





                                       13

litigation and any information that may be subject to attorney-client privilege)
concerning  the Company,  its  subsidiaries  and affiliates  (collectively,  the
"Company  Group")  which was acquired by or  disclosed  to Executive  during the
course of Executive's employment with the Company, and not to disclose the same,
either directly or indirectly, to any other person, firm, or business entity, or
to use it in any way. Such  non-public  information  shall  include,  but not be
limited to, the following:

           (i)  information  which the Company  Group has  compiled to identify,
                develop  and  service  its  clients  and  customers,   including
                "negative  research"  to identify  those  entities  who have not
                subscribed to the services of the Company and its subsidiaries;

           (ii) information which the Company Group has compiled  concerning the
                operations  of the clients and  customers of the Company and its
                subsidiaries,  including  key  contacts  within the clients' and
                customers' business, familiarity with special needs and customer
                characteristics,   workers'  compensation  information,  billing
                rates,  profit  margins,  sales  volumes,  and  other  sensitive
                financial information;

           (iii)information which the Company Group has compiled  concerning the
                employees  and labor force at the Company and its  subsidiaries,
                including  compilations of their names,  addresses,  job skills,
                employment histories and employment records.

Upon termination of Executive's employment,  Executive shall promptly deliver to
the Company all materials of a confidential  nature  relating to the business of
the  Company  and its  subsidiaries  and which  are  Executive's  possession  or
control.  To the extent that  Executive  obtained  information  on behalf of the
Company or any  subsidiary or affiliate  that may be subject to  attorney-client
privilege, Executive shall take reasonable steps to maintain the confidentiality
of such information and to preserve such privilege.

      (c)  Non-Solicitation  of Employees.  During the Employment Period and the
one-year period following any termination of Executive's  employment,  Executive
shall not  directly  or  indirectly,  for his own  benefit  or that of any other
person,  offer any employment in a similar field or business  association to any
of the Company's  employees,  agents or representatives or suggest or in any way
encourage,  any  of  the  Company's  employees,  agents  or  representatives  to
terminate their employment or business association with the Company.

      (d)  Non-Solicitation  of Clients  and  Customers.  During the  Employment
Period  and  the  one-year  period  following  any  termination  of  Executive's
employment, Executive shall not solicit or accept for Executive's own benefit or
the benefits of any other person any of the Company's  customers  and/or clients
with a view to sell or  provide  any  product or  service  competitive  with any
product or service sold or provided or under development by the Company. For the
purposes of this Section 6(d), the term "customers"  shall include any person or
entity to whom the Company has sold, provided or been obligated to provide,  any
service or product,  or who has  otherwise  received any service or benefit from
the Company within the last 24 months or, during the Restriction Period,  within
the 24-month period preceding the date Executive's employment terminates.






                                       14
<PAGE>
      (e)  Company  Property.  Except as  expressly  provided  herein,  promptly
following Executive's  termination of employment,  Executive shall return to the
Company all property of the Company.

      (f)  Injunctive  Relief and Other  Remedies  with  Respect  to  Covenants.
Executive  acknowledges  and  agrees  that  the  covenants  and  obligations  of
Executive with respect to noncompetition,  nonsolicitation,  confidentiality and
Company property, relate to special, unique and extraordinary matters and that a
violation of any of the terms of such  covenants and  obligations  may cause the
Company irreparable injury for which adequate remedies are not available at law.
Therefore,  Executive  agrees  that the  Company  shall be  entitled  to seek an
injunction,  restraining  order or such  other  equitable  relief  (without  the
requirement to post bond) restraining Executive from committing any violation of
the  covenants  and  obligations  contained in this Section 6. This remedy is in
addition  to any other  rights and  remedies  the  Company may have at law or in
equity.

7. Miscellaneous.

noncompetition,   nonsolicitation  and   confidentiality),   7(b)  (relating  to

Arbitration Rules of the American Arbitration  Association then in effect at the
time of the arbitration, and otherwise in accordance with principles which would
be applied by a court of law or equity.  The  arbitrator  shall be acceptable to
both the Company and  Executive.  If the parties  cannot agree on an  acceptable
arbitrator,  the  dispute  shall be heard  by a panel of three  arbitrators  one
appointed  by each of the  parties  and the  third  appointed  by the  other two
arbitrators.

      (c) Binding Effect. This Agreement shall be binding on, and shall inure to
the  benefit  of, the  Company  and any person or entity  that  succeeds  to the
interest of the Company  (regardless of whether such succession does or does not

Company's stock, a merger, consolidation or reorganization involving the Company
or, unless the Company otherwise elects in writing,  a sale of the assets of the
business  of the Company (or  portion  thereof)  in which  Executive  performs a
majority  of his  services.  This  Agreement  shall also inure to the benefit of
Executive's heirs, executors, administrators and legal representatives.

      (d)  Assignment.  Except as provided  under  Section  7(c),  neither  this
Agreement nor any of the rights or  obligations  hereunder  shall be assigned or
delegated by any party  hereto  without the prior  written  consent of the other
party.

the Company the maximum rights permitted at law.

from any course of dealing  between  the  parties  hereto or from any failure by
either  party  hereto to assert its or his rights  hereunder  on any occasion or
series of occasions.

                     SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN


                                    ARTICLE I

                             Background And Purpose
                             ----------------------

1.1 Background.  The Olsten Corporation  Supplemental  Executive Retirement Plan
(the  "Plan")  was  established  effective  January  4,  1999.  The  Plan  is an
amendment,  restatement and continuation of the Olsten Corporation  Supplemental
Retirement Plan for Key Executives Designated by the Company (the "Prior Plan").

1.2 Purpose.  The Plan was  established  for the purpose of  providing  unfunded
deferred  compensation  for a select group of management and highly  compensated
employees as defined in Title I of the Employee  Retirement  Income Security Act
of 1974, as amended.  All  contributions  to the Plan are made by the Company or
Participating Employers.  Participants are not required or permitted to make any
contributions  to the Plan.  The Plan is not  intended  to  qualify  under  Code
section 401(a).



                                   ARTICLE II

                                   Definitions
                                   -----------


2.1 Accrued  Benefit means the benefit  payable to a Participant  under the Plan
determined in accordance with this Section and the provisions of the Plan.

                  (a) A  Participant's  Accrued  Benefit  at his  or her  Normal
                  Retirement  Date  shall  be  equal  to (i)  the  Participant's
                  Benefit Objective  multiplied by a fraction,  the numerator of
                  which is the Participant's  actual Years of Participation upon
                  Termination  of Service  and the  denominator  of which is the
                  Participant's   projected  Years  of  Participation   had  the
                  Participant   remained   employed   by   the   Company   or  a
                  Participating Employer until his or her Normal Retirement Date
                  minus (ii) the Participant's  Integrated Benefits  (calculated
                  as provided in paragraph (b) below).

                  (b) For purposes of  paragraph  (a) above,  the  Participant's
                  Benefit Objective minus the Participant's  Integrated Benefits
                  shall be calculated as follows:

                      (i)    The Participant's  Benefit Objective shall first be
                             expressed as an Actuarially Equivalent lump sum.

                      (ii)   Such  lump  sum  shall   then  be  reduced  by  the
                             Actuarially  Equivalent  lump sum of any Integrated
                             Benefits.

                      (iii)  The resulting  amount shall then be converted  into
                             an Actuarially Equivalent single life annuity.



<PAGE>
                 (c) A  Participant's  Accrued  Benefit  at  his  or  her  Early
                 Retirement  Date  shall be equal to the  Participant's  Accrued

                 Participant's  projected  Years of Service at his or her Normal

Participant  does not qualify to receive  benefits under the Company's long term
disability program,  the Plan Administrator may nevertheless  determine that the

                 Participating  Employer  on or  after  January  4,  1999,  such
                 Employee's  benefits shall be determined  exclusively under the
                 terms of the Prior Plan. For Employees who first participate in
                 the Plan on or after January 4, 1999,  the Prior Plan shall not
                 have any effect on the benefits payable under this Plan.

                 (c) Highly Compensated Employees who are age twenty-one (21) or

                 Company as eligible to  participate  in the Plan,  shall become
                 Participants as of their Entry Date.

                 (d) The Company shall have sole  discretion  to determine  when
                 and if an Employee becomes eligible to participate in the Plan.

designee will notify eligible Highly Compensated  Employees in writing when they
have been selected for participation in the Plan.

3.3 Suspension of Participation.

                 (a) A Participant's  participation in the Plan may be suspended
                 by the Company due to a  diminution  of  responsibilities.  The
                 Chief Executive Officer or his or her designee shall notify the
                 Participant  in writing if his or her  participation  hereunder
                 shall  be  suspended,  including  the  effective  date  of such





                                      -9-
<PAGE>
                 suspension. Participants whose participation hereunder has been
                 suspended  shall  continue to earn Years of Service for vesting
                 purposes  with  respect to the  Accrued  Benefit  earned by the
                 Participant  prior to the  effective  date of such  suspension.
                 However,  Participants whose  participation  hereunder has been
                 suspended shall cease accumulating  additional Accrued Benefits
                 as of the effective date of the suspension.

                 (b) A Participant whose  participation in the Plan is suspended
                 under Section 3.3(a) shall be eligible to resume  participation
                 in the Plan at such time as the Company may determine. Upon the
                 resumption of participation in the Plan, the Participant  shall
                 earn  additional  Years of  Participation  for benefit  accrual
                 purposes, but only with respect to those Years of Participation
                 occurring  before the  suspension  and after the  resumption of
                 participation.  Unless the Company provides otherwise, Years of
                 Participation shall not be credited for the period during which
                 the   suspension  of  the   Participant's   participation   was
                 effective.

4.1 Funding.

                 (a) The Company or  Participating  Employer  may deposit into a
                 Trust any  amounts  it deems  appropriate  to fund the  Accrued
                 Benefits  described  in the Plan.  To the  extent  the Trust is
                 unable  or not  required  to pay  such  Accrued  Benefits,  the
                 Accrued  Benefits shall be paid by the Company or Participating
                 Employer as and when they become due as provided herein.

                 (b) Nothing  contained herein shall be deemed to create a trust
                 of  any  kind  or  create  any  fiduciary  relationship.  Funds
                 deposited  into the Trust shall continue for all purposes to be
                 a part of the  general  funds of the  Company or  Participating
                 Employer  and no person  other than the  Company or  respective
                 Participating  Employer  shall, by virtue of the Plan, have any
                 interest in such funds.  To the extent that any person acquires
                 a right to receive payments from the Company or a Participating
                 Employer  under the Plan,  such right shall be no greater  than
                 the right of any unsecured  general  creditor of the Company or
                 the Participating Employer.

                 (c)  Should  any  insurance  contract  or other  investment  be
                 acquired in connection with the liabilities  assumed under this
                 Plan,   it  is  expressly   understood   and  agreed  that  the
                 Participants  and  Beneficiaries  shall not have any right with
                 respect  to, or claim  against,  such assets nor shall any such
                 purchase  be  construed  to  create  a trust  of any  kind or a
                 fiduciary  relationship  between  the  Company,   Participating
                 Employers  and the  Participants,  Beneficiaries  or any  other
                 person.  The  Company,  Participating  Employer or the Trust(s)
                 shall be  designated  owner and  beneficiary  of any  insurance
                 contract  acquired in connection with its obligation under this
                 Plan.

                 (d) Each Participant and Beneficiary  shall be required to look
                 to the provisions of this Plan and to the Company or respective
                 Participating  Employer for enforcement of any and all benefits
                 under this Plan. To the extent any such person acquires a right
                 to receive  payment  under this  Plan,  such right  shall be no
                 greater than the right of any unsecured general creditor of the
                 Company or Participating Employer, respectively.

4.2 Insolvency.

                 (a) The Participant's interest in his or her benefits under the
                 Plan shall be  payable  under the Trust and shall be subject to
                 the solvency of the Company or Participating Employer.

                 (b) Should the Company or Participating  Employer be considered
                 insolvent  such that the Company or  Participating  Employer is
                 unable  to pay  current  obligations  as  they  come  due or is
                 subject to a proceeding  under the federal  Bankruptcy  Code or
                 should the Company or  Participating  Employer  become aware of
                 its pending  insolvency  or  bankruptcy,  the affected  entity,
                 acting  through  its  board of  directors  or  chief  executive
                 officer shall give immediate written notice of such to the Plan
                 Administrator and the Trustee.

                 (c) Upon receipt of such notice, the Plan Administrator and the
                 Trustee  shall cease to make any  payments to  Participants  or
                 Beneficiaries of the affected entity and shall hold any and all
                 assets with respect to those Participants and Beneficiaries for
                 the benefit of the general unsecured  creditors of such entity.
                 For this purpose,  it is expressly  provided that the assets of
                 the Company and each Participating  Employer which are intended
                 for use in  this  Plan  shall  at all  times  be  available  to
                 creditors of such entity.  The Plan shall be administered on an
                 employer-by-employer  basis,  such  that  the  assets  of  each
                 Participating   Employer   (including  the  Company)  that  are
                 available to the creditors of that Participating Employer shall
                 equal the  liabilities  accrued on behalf of the  employees  of
                 that Participating Employer.  Furthermore,  the assets of other
                 Participating  Employers  (including  the Company) shall not be
                 available  to satisfy  the claims of any  creditor of any other
                 entity whose employees participate in this Plan.

4.3 Amounts Not Made  Available.  No amounts held in the Trust or recorded as an
Accrued  Benefit  hereunder  shall  be  made  available  to the  Participant  or
Beneficiaries, except as provided for distributions described in Article VII.

4.4  Contingent  Nature of Accrued  Benefits.  Until the  Accrued  Benefits  are
distributed under the Plan to the Participants or Beneficiaries, the interest of
each  Participant and Beneficiary in this Plan is contingent only and is subject
to forfeiture as provided  hereunder.  Title to and beneficial  ownership of any
assets,  whether  cash or  investments,  which the  Company  or a  Participating
Employer  may set aside to meet its  contingent  deferred  obligation  hereunder
shall at all times remain the property of the Company or Participating  Employer
and no  Participant  or Beneficiary  shall under any  circumstances  acquire any
property  interest  in any  specific  assets  of the  Company  or  Participating
Employer.

                             -----------------------


5.1 Normal  Retirement.  If a Participant has a Termination of Service on his or

her  death,  Disability  or Early  Retirement  Date,  the  Participant  shall be

5.5 Death.  Notwithstanding Section 5.8, if a Participant dies before his or her
Normal Retirement Date or Late Retirement Date while in Active Service, then, in
accordance with Section 6.2, a pre-retirement  survivor annuity shall be paid to
such Participant's Beneficiary as soon as practicable following the later of (i)
the  Participant's  death or (ii) the  Participant's  Early Retirement Date. The

Participant  shall be entitled to receive his or her Accrued Benefit in the form

determined to be Disabled. The amount of the Participant's Accrued Benefit shall
be reduced by the amount of payments  that the  Participant  could have received
from any long term disability  insurance  program  sponsored by the Company or a
Participating Employer, based on the highest long term disability benefit option
made available to the Participant by the Company or Participating Employer.

5.7 Vesting and Forfeitures.

                 (a) A  Participant  shall  become  fully  vested  in his or her

                 Retirement Age, death or Disability.

                 (b) Except as  provided  in (a),  a  Participant  shall  become
                 vested in his or her Accrued Benefit as follows:

                           Years of Service
                           Following Entry

                           ----------------                   -----------------

                 Participant's  Termination  of Service.  The  forfeited  amount

                 accordance  with  the  last  valid  designation  filed  by  the
                 Participant with the Plan Administrator; provided however, that
                 the only  forms of benefit  available  under the Plan are those
                 forms which are described in Sections 6.1 and 6.2.

<PAGE>
                 (b) The  designation of the time and form of payment shall only
                 be  valid  if (i)  the  designation  is  filed  with  the  Plan
                 Administrator at least six (6) months before the  distributions
                 begin and no later  than the last day of the Plan  Year  before
                 the first  Plan Year for which  such  designation  is to apply;
                 (ii)  the  designation  is filed  with  the Plan  Administrator
                 during  the first  thirty  (30) days  that the  Participant  is
                 eligible  to  participate  in the  Plan  and  the  distribution
                 commencement  date begins not earlier than the first day of the
                 calendar year following the date the  designation is filed with
                 the Plan Administrator; or (iii) thirty (30) days from the date
                 this Plan is effective for eligible employees.

                 (c) If the designation is not valid under Section  5.8(b),  the
                 Participant's previous designation shall be reinstated.

                 (d) Except as provided in this section 5.8(d), in the event the
                 Participant does not have a valid designation of a distribution
                 commencement date and form of benefit under this section,  then
                 the  Participant  shall be deemed to have  elected to receive a
                 five   (5)   year   installment   payment   beginning   on  the
                 Participant's  Normal  Retirement  Date, as provided in Section
                 6.1, or in the case of the Participant's  death while in Active
                 Service,  a survivor  annuity,  as  provided  in  Section  6.2.
                 Installment payments shall be made in a manner that distributes
                 at  least  fifty  thousand   dollars   ($50,000)   annually  to
                 Participants (but no more than the Accrued Benefit),  provided,
                 however,  that the final  installment  may be less  than  fifty
                 thousand dollars  ($50,000) if necessary in order to distribute
                 the  remainder  of  the  Participant's   Accrued  Benefit.  For
                 example, if the Participant's Accrued Benefit is $230,000,  the
                 Participant would receive installments of $50,000 over four (4)
                 years and the Participant's final installment would be $30,000.

                 (e) For purposes of this Section 5.8 only, the phrase "the date
                 this Plan is effective for eligible  employees"  shall mean the
                 date  on  which  the  Plan   Administrator   first  provides  a
                 distribution election form under this Plan to a Participant.

5.9 Special Rule for Change in Control.  Notwithstanding  anything herein to the
contrary,  in the  event of a Change  in  Control,  Participants  shall be fully
vested in the value of their Accrued Benefit.

                                  -------------


6.1 Forms of Payment.

                 (a) Except as  provided  in  Section  6.2,  the normal  form of
                 payment under the Plan is a single life annuity. Under a single
                 life  annuity,  benefits  will be paid on the first day of each
                 month to the Participant for the remainder of the Participant's
                 lifetime,  with the last payment being made on the first day of
                 the month in which the Participant dies.  Survivor benefits are
                 not payable under a single life annuity, regardless of when the
                 Participant  dies.  The  Plan  Administrator  shall  have  sole
                 discretion to select the payor of the single life annuity.

                 (b) A Participant may elect, in accordance with Section 5.8, to
                 receive  distribution  of his or her Accrued  Benefit in a form
                 that is an  Actuarial  Equivalent  to a single life annuity and
                 payable as:

                      (i)    a single, lump sum payment;

                      (ii)   installments over five (5) or ten (10) years; or

                      (iii)  a joint and survivor annuity.

                 (c) Installments  shall be payable  monthly,  bi-weekly or more
                 frequently,  at the discretion of the Plan Administrator.  If a
                 Participant   dies   while   receiving   installment   payments
                 hereunder,  the Plan Administrator may elect to continue paying
                 such  installments  to  the  Participant's  Beneficiary  or  to
                 convert  the  remaining  installment  payments  to a  lump  sum
                 payment   to   the   Participant's   Beneficiary.    The   Plan
                 Administrator shall have sole discretion to select the payor of
                 installment  benefits  and  whether  to convert  the  remaining
                 installment payments to a lump sum.

                 (d) Periodic payments under a joint and survivor annuity may be
                 made from proceeds of a commercial  annuity  contract which the
                 Company or Participating Employer may establish with an annuity
                 provider whereby the Company or  Participating  Employer may be
                 the annuitant under the contract.  The Plan Administrator shall
                 have  sole  discretion  to  select  the  payor of the joint and
                 survivor  annuity and the  frequency of the payments to be made
                 to the Participant and his or her Beneficiary.

6.2 Pre-Retirement Death Distributions.

                (a)  Unless the Plan  Administrator  provides  otherwise,  if a
                 Participant  dies  before  beginning  to receive  distributions
                 under the Plan, the  Participant's  Beneficiary shall receive a
                 pre-retirement  survivor  annuity,  equal to the  Participant's
                 Accrued  Benefit  as of his or her date of  death,  payable  in



                                      -15-
<PAGE>
                 monthly  installments  over the  Beneficiary's  life expectancy
                 beginning on the later of (i) the  Participant's  death or (ii)
                 the  Participant's  Early  Retirement  Date.  Unless  the  Plan
                 Administrator provides otherwise, if the Participant dies after
                 beginning  to  receive  distributions  under  the  Plan and has
                 elected  other than a Straight Life  Annuity,  the  Beneficiary
                 shall  continue  receiving the payments  which would  otherwise
                 have been made to the  Participant,  in  accordance  with their
                 distribution election under Section 5.8.

                 (b) If the Plan has not purchased a commercial  annuity to fund
                 the Beneficiary's  pre-retirement death benefits, then upon the
                 death  of the  Beneficiary,  if any  amounts  remain  from  the
                 Participant's  Accrued Benefit,  such amount shall be paid in a
                 lump sum to the  Beneficiary's  estate  as soon as  practicable
                 following  the  date of the  Beneficiary's  death.  If the Plan
                 purchases  a  commercial  annuity  to  fund  the  Beneficiary's
                 pre-retirement  death  benefits,  payments shall cease upon the
                 Beneficiary's  death.  The Plan  Administrator  shall have sole
                 discretion to select the payor of the  pre-retirement  survivor
                 annuity.

7.1 Adoption  by  Other  Employers.  Notwithstanding  anything   herein  to  the
contrary,   a  Participating   Employer  may,  with  the  consent  of  the  Plan
Administrator  and the Trustee,  adopt the Plan and all of the provisions hereof
under such procedures as the Plan  Administrator may determine.  The Plan is not

Company  to a  Participating  Employer  or from one  Participating  Employer  to
another (or vice versa) shall not affect the Participant's rights under the Plan

interrupted  for any purpose of the Plan.  Transfer of  employment  between such
entities  shall not be treated as a  Termination  of Service with the Company or

prior  Participating  Employer and distributions shall not be made from the Plan
based on such a transfer of employment.  The entity to which the  Participant is
transferred  shall  thereupon  become  obligated  hereunder with respect to such
Participant  in  the  same  manner  as  was  the  organization  from  which  the
Participant was transferred.

7.5 Contributions and Forfeitures of Participating  Employer.  All contributions
made by a Participating Employer may be determined separately and may be paid to

                 or terminate its  participation  in the Plan at any time,  upon
                 giving reasonable advance notice to the Company. At the time of
                 any such discontinuance or termination,  satisfactory  evidence
                 thereof shall be delivered to the Trustee and  distribution  of
                 Accrued Benefits held in the Trust for the benefit of employees
                 of the  withdrawing  employer  shall be  distributed as soon as
                 administratively   feasible,   unless  the  Plan  Administrator
                 provides otherwise.

                 (b) If the Plan  Administrator  elects  not to  distribute  the
                 Accrued Benefits of affected  Participants under (a) above, the
                 Plan  Administrator  may  suspend  the  affected  Participant's
                 participation in the Plan, in accordance with Section 3.3.

their written consent;  or (ii) directly or indirectly  reduce any Participant's
Accrued Benefit.  Notwithstanding anything herein to the contrary, this Plan may
be amended at any time if necessary or desirable to conform the Plan to the Code
or any federal  statute with respect to employees'  trusts or any regulations or
rulings  issued  pursuant  thereto  and no such  amendment  shall be  considered
prejudicial to the rights of any Participant.  Notice of all material amendments

and its assets or liabilities  may not be transferred to any other plan,  unless
each person  entitled to benefits  under the Plan would,  if the resulting  plan

she  would  have  been  entitled  to  receive  immediately  before  the  merger,

                                ----------------


10.1 Claims Submission.

                 (a) All claims for benefits  under the Plan by a Participant or
                 Beneficiary,  regardless  of the nature of the claim,  shall be
                 initially submitted in writing to the Plan Administrator.  Such
                 claims  shall be submitted  within a reasonable  period of time
                 after  the date  such  benefit  was,  or was  purported  to be,
                 available  to  the  Participant  or   Beneficiary,   with  such
                 determination  of   reasonableness  to  be  made  by  the  Plan
                 Administrator   in  its  sole   discretion.   All  claims  must
                 adequately  state the basis for the claim including a statement
                 of all pertinent facts and applicable law, except to the extent
                 expressly waived by the  Administrator.  The  Administrator may
                 prescribe  additional  procedural  requirements for claims, not
                 inconsistent herewith.

                 (b) In the event that a  Participant  or  Beneficiary  does not
                 receive any Plan benefit that is claimed,  such  Participant or
                 Beneficiary  shall be entitled to  consideration  and review as
                 provided in this Article.  Such  consideration and review shall
                 be conducted in a manner  designed to comply with ERISA section
                 503.

                 (c) Failure to follow the  requirements  of this Article  shall
                 result in the denial of the claim submitted. The Participant or
                 Beneficiary  submitting such deficient claim shall be deemed to
                 have not exhausted his or her administrative remedies under the
                 Plan.

forth (in a manner calculated to be understood by the claimant):

                 (a) the specific reason or reasons for denial of the claim;

                 (b) a specific  reference to the Plan  provisions  on which the
                 denial is based;

                 (c) a description  of any  additional  material or  information
                 necessary  for  the  claimant  to  perfect  the  claim  and  an
                 explanation  of why such material or  information is necessary;
                 and

                 (d) an explanation of the provisions of this Article.

10.3 Right of Appeal.  A claimant who has a claim denied under  section 10.2 may
appeal for  reconsideration of that claim. A request for  reconsideration  under
this section must be filed by written notice with the Plan Administrator  within
sixty (60) days  after  receipt by the  claimant  of the notice of denial  under
section 10.2.

10.4 Review of Appeal.  Upon receipt of an appeal,  the Company  shall  promptly
assign a committee or appropriate  officer independent of the Plan Administrator
to  review  the Plan  Administrator's  denial  of the  claim.  Such  independent
committee or officer shall take action to give due  consideration to the appeal.
Such  consideration  may  include  a hearing  of the  parties  involved,  if the
committee or officer  feels such a hearing is  necessary.  In preparing for this
appeal the claimant shall be given the right to review  pertinent  documents and
the right to submit  in  writing a  statement  of  issues  and  comments.  After
consideration of the merits of the appeal,  the committee or officer shall issue
a written decision which shall be binding on all parties.  The decision shall be
written  in a manner  calculated  to be  understood  by the  claimant  and shall
specifically state its reasons and pertinent Plan provisions on which it relies.
The  decision  on the appeal  shall be issued  within  sixty (60) days after the
appeal is filed,  except that if a hearing is held,  the  decision may be issued
within one hundred twenty (120) days after the appeal is filed.

10.5 Designation.  The  Plan  Administrator  may  designate  one  or more of its
members or any other person of its choosing to make any determination  otherwise
required to be made by the Plan Administrator under this Article.

     2.   CONSULTING ARRANGEMENT
          ----------------------

          2.1.  Consulting  Services.  From and after the  Effective  Time,  the
Executive shall provide  services as a consultant to Adecco and its subsidiaries
as contemplated by this  Agreement,  and the Executive  hereby agrees to provide
such  consulting  services  and to  comply  with the  other  provisions  of this
Agreement, upon the terms and subject to the conditions hereinafter set forth.

          2.2.  Nature of  Consulting  and Other  Services.  In his rendering of
consulting  services for the benefit of Adecco and its  subsidiaries  hereunder,
the  Executive  shall  from  time to time  provide  Adecco,  Adecco's  Board  of
Directors,  and Adecco's  executive officers with such advice as any of them may
reasonably  request in connection with the business and operations of Adecco and
its subsidiaries and affiliates. The Executive shall provide such advice only at
the  request of Adecco's  Board of  Directors  or its  executive  officers.  The
Executive  shall hold himself  available at  reasonable  times and on reasonable
notice to render such consulting and advisory  services as may be so assigned to
him by Adecco,  Adecco's  Board of  Directors,  or Adecco's  executive  officers

during the Consulting Term (as defined below);  provided,  however, that, unless
the parties  otherwise agree, the consulting and advisory  services  rendered by
the Executive  during the  Consulting  Term shall not exceed  fifteen (15) hours
each calendar month.  Without limiting the foregoing,  the Executive shall, upon
the reasonable  request of the persons  specified above, (a) consult with Adecco
and its  subsidiaries  with  respect to all  matters  concerning  the Company or
Adecco in which the  Executive  had  personal  involvement  during his period of
employment and/or directorship with the Company or Adecco, (b) assist Adecco and
its  subsidiaries in the negotiation  and  consummation of business  matters and
prospects  pending  at  the  time  of the  termination  of  his  employment  and
thereafter,  and (c) cooperate  with and assist Adecco and its  subsidiaries  in
undertaking  and  preparing  for  legal and other  proceedings  relating  to the
affairs  of Adecco  and its  subsidiaries.  In  connection  with the  consulting
services  rendered by him  hereunder,  the Executive  shall (i)  undertake  such
travel on Adecco's or Adecco's subsidiaries' behalf (and at Adecco's or Adecco's
subsidiaries'  expense)  as  Adecco  and the  Executive  shall  agree,  and (ii)
negotiate as Adecco's or its subsidiaries' representative when and as reasonably
requested to do so by Adecco's Board of Directors or its executive officers.

          2.3.  Nature of Consulting and Other  Services.  It is understood that
the  Executive  is to  act  as a  consultant  and  advisor  to  Adecco  and  its
subsidiaries, and is not an employee or agent of, or co-venturer with, Adecco or
any of its  subsidiaries  in any  respect.  The  Executive  shall have no right,
authority,  or power to act for or on Adecco's behalf other than as described in
Section 2.2 above. The relationship between Adecco and its subsidiaries,  on the
one  hand,  and  the  Executive,  on the  other,  hereunder  shall  be  that  of
independent contractor.

     3.   TERM
          ----

          The  Executive  hereby  agrees  to  provide  the  consulting  services
contemplated  by this Agreement for a term of five (5) years,  commencing at the
Effective Time and  terminating  on the fifth  anniversary of the Effective Time
(the "Consulting  Term."). In the event of the death or permanent  disability of
the Executive  after the Effective  Time and prior to the end of the  Consulting
Term, the remaining fees under Sections 4.1 and 4.2 that would have been payable
through the end of the Consulting Term shall continue to be paid through the end
of the  Consulting  Term to the  Executive  or, in the event of the  Executive's
death,  to the  beneficiary  designated in writing by the Executive  (or, in the
absence of a designated  beneficiary  who survives  the  Executive,  Executive's
estate).

     4.   CONSULTING, NON-COMPETITION AND NON-SOLICITATION FEES
          -----------------------------------------------------

          4.1.  Consulting  Fees. In  consideration  of the consulting  services
provided  hereunder,  the Company shall pay the  Executive an annual  consulting
fee, in cash, in the amount of Two Hundred  Thousand  Dollars  ($200,000)  (less
amounts  required  to be  withheld  under  applicable  law)  payable  during the
Consulting  Term.  Such annual  consulting  fee shall be payable in advance on a
quarterly basis. The fees payable to the Executive  hereunder shall,  subject to
the other terms and provisions of this  Agreement,  continue for the full period
of the  Consulting  Term even if the  Executive  obtains  income  from any other
source, including other full-time employment.




                                       3
<PAGE>
          4.2.  Non-Competition and  Non-Solicitation  Fees. In consideration of
the covenants undertaken by the Executive under Sections 6.1 and 6.2 hereof, the
Company  shall  pay  the   Executive:   (a)  a  one-time   non-competition   and
non-solicitation   fee,  in  cash,  in  the  amount  of  Eight  Million  Dollars
($8,000,000)  (less  amounts  required to be  withheld  under  applicable  law),
payable  at  the  Effective  Time,  and  (b)  an  annual   non-competition   and
non-solicitation  fee, in cash,  in the amount of Two Hundred  Thousand  Dollars
($200,000) (less amounts required to be withheld under applicable law),  payable
during the Consulting Term. Such annual non-competition and non-solicitation fee
shall be  payable  in  advance on a  quarterly  basis.  The fees  payable to the
Executive  hereunder  shall,  subject to the other terms and  provisions of this
Agreement,  continue  for the full  period  of the  Consulting  Term even if the
Executive  obtains  income  from any other  source,  including  other  full-time
employment.

          4.3.  Business  Expenses.  During the  Consulting  Term, the Executive
shall be entitled to receive prompt  reimbursement  for all reasonable  business
expenses  incurred  by the  Executive  in  connection  with the  performance  of
Executive's  consulting and advisory services for the Company in accordance with
the  policies  and  practices of the Company as in effect from time to time with
respect to employees of the Company.

          4.4.  Director  Compensation.  In the event  that the  Executive  is a
member of Adecco's or the Company's  Board of Directors,  the Executive shall be
entitled  to receive all  compensation  and fees as are payable by Adecco or the
Company,  as  applicable,  to its directors  from time to time.  Notwithstanding
anything contained herein, time spent by the Executive in the performance of his
services as a member of Adecco's or the Company's  Board of Directors  shall not
be deemed to be the performance of consulting services hereunder.

          4.5.  Automobile  Lease.  The  Company  shall  pay  or  reimburse  the
Executive for the lease payments (in a monthly amount not to exceed $1,000) with
respect to the  automobile  leased by the  Executive,  or by the Company for the
Executive's  benefit,  under the lease that is in effect on the date hereof. The
Company shall make such payments or  reimbursement  until the end of the term of
such lease (or, if earlier, until the end of the Consulting Term.)

          4.6. Medical  Benefits.  During the Consulting Term, the Company shall
provide the Executive (and the Executive's  dependents)  with the coverage under
the Company's group medical plan or plans that is provided to executive officers
of the Company (and their  dependents) under the terms of such plan or plans, as
in effect from time to time.

     5.   CONFIDENTIALITY
          ---------------

          5.1.  Confidentiality.  The Executive  acknowledges  that,  during the
course of his employment with the Company, the Executive has had, and during the
course of his engagement under this Agreement the Executive will have, access to
Confidential  Information  (as defined below) owned by the Company and/or Adecco
or used or involved in or incidental to their operations,  business and affairs.
All  such  Confidential  Information  has  been  and  will be  disclosed  to the
Executive  in  confidence.  The  Executive  covenants  that  from and  after the
Effective Time, he (a) will keep  confidential all  Confidential  Information of





                                       4
<PAGE>
Adecco and its  subsidiaries  and affiliates  which is known to him and,  except
with the specific prior written consent of Adecco or as required to be disclosed
by law or the order of any agency, court or other governmental  authority,  will
not disclose any Confidential  Information to any person other than Adecco,  its
subsidiaries and affiliates, or their respective employees accountants,  counsel
and other  designated  representatives  as is  appropriate  in the course of his
consulting  relationship,  and (b)  will not make  any  public  statement  which
disparages  Adecco  or any  of its  subsidiaries  or  any  of  their  respective
employees, officers or directors, which is materially damaging to Adecco and its
subsidiaries  taken as a whole.  For purposes of this  Agreement,  "Confidential
Information"  shall mean all  know-how,  trade  secrets  and other  confidential
nonpublic information prepared for, by or on behalf of, or in the possession of,
the  Company,  Adecco  or any of their  subsidiaries  or  affiliates,  including
without limitation (i) nonpublic proprietary information; (ii) other information
derived  from  reports,  investigations,  research,  studies,  work in progress,
codes, marketing,  sales or service programs, capital expenditure projects, cost
summaries,  equipment,  product or system designs or drawings,  pricing or other
formulae, contract analyses, financial information, projections, agreements with
vendors,  joint venture agreements,  confidential filings with any agency, court
or  other  governmental  authority;  and  (iii)  all  other  concepts,  methods,
techniques and processes of doing  business,  ideas or  information  that can be
used in the  operation  of a business or other  enterprise  and is  sufficiently
valuable, or potentially  valuable,  and secret to afford an actual or potential
economic advantage over others; provided, however, that Confidential Information
shall not include any information that is currently  generally  available to and
generally  known by the public or, through no fault of the Executive,  hereafter
becomes generally available to and generally known by the public.

          5.2. Business Property. All records,  files,  drawings,  documents and
the like relating to Adecco's or the  Company's  business or the business of any
of their  subsidiaries or affiliates  which the Executive shall prepare,  use or
come into contact with, shall be and remain Adecco's sole property and shall not
be removed from the premises of Adecco,  the Company or their  subsidiaries  and
affiliates  without its written  consent except as required in the course of the
Executive's consulting engagement.  Upon the termination of the Consulting Term,
all such  records,  files,  drawings,  documents  and the  like  that are in the
Executive's  custody or control shall  immediately be delivered by the Executive
to Adecco or its designee.  The Executive  acknowledges  that his obligations in
this  Section  are of a unique  character  that  gives  them a special  value to
Adecco,  the loss of which cannot  reasonably or adequately  be  compensated  in
damages in an action at law,  that a breach  thereof will result in  irreparable
and  continuing  harm to Adecco  and its  subsidiaries  and that  therefore,  in
addition  to any other  remedy  that Adecco or the Company may have at law or in
equity,  Adecco and/or the Company shall be entitled to injunctive  relief for a
breach thereof by the Executive.

     6.   NONCOMPETITION AND NONSOLICITATION
          ----------------------------------

          6.1. Noncompetition.  The Executive covenants that he will not, during
the  period  commencing  at the  Effective  Time and  terminating  on the  fifth
anniversary  of  the  Effective  Time  (the  "Restricted  Period"),  (a)  accept
employment  with or render service to any person,  firm or  corporation  that is
engaged in the  business(es)  conducted by Adecco or any of its  subsidiaries or





                                       5
<PAGE>
affiliates  (as  determined  from time to time) in any market in which Adecco or
any of such subsidiaries or affiliates is then conducting such business(es);  or
(b)  own,  manage,  operate,  or  control,  or  participate  in  the  ownership,
management,  operation,  or control of, or be connected  as a principal,  agent,
representative,   consultant,  advisor,  investor,  owner,  partner,  financier,
contractor,  manager or joint venturer with, or permit his name to be used by or
in connection or  association  with,  any person,  firm or  corporation  that is
engaged in the  business(es)  conducted by Adecco or any of its  subsidiaries or
affiliates  in any  market  in  which  Adecco  or any  of  its  subsidiaries  or
affiliates is then conducting such  business(es);  provided,  however,  that the
Executive may invest as an investor in the voting  securities of any person that
is a reporting company under the Securities Exchange Act of 1934, as amended, so
long as the aggregate  amount of the  securities  the Executive owns directly or
indirectly  is less  than five  percent  (5%) of the  total  outstanding  voting
securities  of that person.  Notwithstanding  anything  contained  herein to the
contrary,  the Executive shall not be prohibited from accepting employment with,
rendering services to or otherwise engaging in any activity or capacity with any
entity  engaged  in the  Health  Services  Business  (as  defined  in the Merger
Agreement).

          6.2. Nonsolicitation. The Executive covenants that he will not, during
the  Restricted  Period,  otherwise  than  on  behalf  of  Adecco  or any of its
subsidiaries  or  affiliates  (as  determined  from time to time),  solicit  the
employment of any person,  or induce or advise any person to leave the employ of
Adecco or any of such  subsidiaries or affiliates,  if such person is, as of the
date of such  solicitation,  inducement  or  advisement,  employed on a full- or
part-time basis by Adecco or any of its subsidiaries or affiliates.

          6.3. Breach by Executive.  Notwithstanding  anything contained herein,
in the  event  that  the  Executive  materially  breaches  any of the  covenants
undertaken by him under Section 6.1 or 6.2, the Company's obligation to make the
compensation  payments and benefits provided for in Section 4.1, 4.2, 4.5 or 4.6
hereof  shall  automatically  terminate  (other  than with  respect  to any such
payments  earned by the  Executive  through  the date of breach  which  have not
theretofore been paid), and the Executive shall automatically forfeit all of his
right to and interest in such payments.

          6.4.  Modification.   If  the  noncompetition  and/or  nonsolicitation
covenants  contained in the  foregoing  Sections 6.1 and 6.2 are, in the view of
any court or arbitrator  asked to rule upon the issue,  deemed  unenforceable by
reason of  covering  too large an area,  too long a period of time,  too large a
number of  entities  or too many  business  activities,  then the same  shall be
deemed to cover only the largest area, the longest period, the largest number of
entities  or the most  business  activities,  as the case may be,  that will not
render it unenforceable.

          6.5. Specific Performance.  The Executive acknowledges and agrees that
Adecco and the Company cannot be fully or adequately  compensated in damages for
a violation  of Section 6.1 or 6.2  hereof,  and that,  in addition to any other
relief to which Adecco or the Company may be  entitled,  it shall be entitled to
injunctive and equitable relief.

     7.   EXCISE TAX GROSS-UP
          -------------------

          (a) Anything in this Agreement to the contrary notwithstanding,  if it
shall  be  determined  that  any  payment,   distribution  or  benefit  provided
(including, without limitation, the acceleration of any payment, distribution or
benefit  and the  acceleration  of  exercisability  of any stock  option) to the
Executive  or for  his  benefit  (whether  paid or  payable  or  distributed  or
distributable)  pursuant  to the  terms  of this  Agreement  or  otherwise  (the
"Payment")  would be subject,  in whole or in part, to the excise tax imposed by
section 4999 of the Internal  Revenue Code of 1986, as amended (the "Code") (the
"Excise Tax"),  then the Executive shall be entitled to receive from the Company
an additional  payment (the  "Gross-Up  Payment") in an amount such that the net
amount of the Payment and the Gross-Up  Payment  retained by Executive after the
calculation  and  deduction  of all Excise  Taxes  (including  any  interest  or
penalties  imposed  with  respect to such taxes) on the Payment and all federal,
state and local income tax,  employment  tax, self employment tax and Excise Tax
(including any interest or penalties  imposed with respect to such taxes) on the
Gross-Up Payment provided for in this Section 7 and taking into account any lost
or reduced tax deductions on account of the Gross-Up Payment,  shall be equal to
the Payment;

          (b) All  determinations  required  to be made  under  this  Section 7,
including  whether and when the  Gross-Up  Payment is required and the amount of
such  Gross-Up  Payment,  and the  assumptions  to be used in  arriving  at such
determinations  shall be made by the  Accountants (as defined below) which shall
provide  the  Executive,   Adecco  and  the  Company  with  detailed  supporting
calculations with respect to such Gross-Up Payment within ninety (90) days after
the Effective Time. For the purposes of this Section 7, the "Accountants"  shall
mean  PriceWaterhouseCoopers.  For  purposes  of  determining  the amount of the
Gross-Up  Payment,  Executive shall be deemed to pay Federal income taxes at the
applicable  marginal  rate of federal  income  taxation for the calendar year in
which the  Gross-Up  Payment is to be made and to pay any  applicable  state and
local income taxes at the applicable  marginal rate of taxation for the calendar
year in which  the  Gross-Up  Payment  is to be made,  net of the  reduction  in
federal income taxes which could be obtained from the deduction of such state or
local  taxes if paid in such year  (determined  with  regard to  limitations  on
deductions based upon the amount of Executive's  adjusted gross income).  To the
extent  practicable,  any Gross-Up  Payment with respect to any Payment shall be
paid by the Company at the time Executive is entitled to receive the Payment and
in no event  shall any  Gross-Up  Payment  be paid  later than 30 days after the
receipt by the Executive of the Accountants' determination. Any determination by
the Accountants  shall be binding upon the Company and Executive,  including for
purposes of withholding on amounts payable under this Agreement.  As a result of
uncertainty  in the  application  of Section 4999 of the Code at the time of the
initial  determination  by the  Accountants  hereunder,  it is possible that the
Gross-Up  Payment made will have been an amount that is greater or less than the
Company  should  have  paid  pursuant  to this  Section 7 (an  "Overpayment"  or
"Underpayment,"  respectively).  In the  event  that  the  Gross-Up  Payment  is
determined by the Accountants or pursuant to any proceeding or negotiations with
the Internal Revenue Service to be less than the amount initially  determined by
the  Accountants,  the Executive  shall  promptly  repay the  Overpayment to the
Company;  provided,  however,  that in the event  any  portion  of the  Gross-Up
Payment to be repaid to the Company has been paid to any Federal, state or local





                                       7
<PAGE>
tax  authority,  repayment  thereof shall not be required until actual refund or
credit of such  portion  has been made to the  Executive.  In the event that the
Company  exhausts  its remedies  pursuant to Section  7(c) and the  Executive is
required to make a payment of any Excise Tax, the Underpayment shall be promptly
paid by the Company to or for the Executive's benefit; and

          (c) The  Executive  shall notify  Adecco and the Company in writing of
any claim by the Internal Revenue Service that, if successful, would require the
payment by the Company of the Gross-Up Payment. Such notification shall be given
as soon as practicable  after the Executive is informed in writing of such claim
and shall  apprise  Adecco  and the  Company of the nature of such claim and the
date on which such claim is requested to be paid.  The  Executive  shall not pay
such claim prior to the  expiration of the 30-day  period  following the date on
which the Executive gives such notice to Adecco and the Company (or such shorter
period ending on the date that any payment of taxes,  interest and/or  penalties
with respect to such claim is due).  If the Company  notifies  the  Executive in
writing  prior to the  expiration of such period that it desires to contest such
claim, the Executive shall:

               (i) give the Company any information reasonably requested by
     the Company relating to such claim;

               (ii) take such action in  connection  with  contesting  such
     claim as the Company shall reasonably  request in writing from time to
     time,  including,  without limitation,  accepting legal representation
     with respect to such claim by an attorney  reasonably  selected by the
     Company;

               (iii)  cooperate  with the Company in good faith in order to
     effectively contest such claim; and

               (iv) permit the Company to  participate  in any  proceedings
     relating to such claims;

provided,  however,  that the Company  shall bear and pay directly all costs and
expenses  (including  additional  interest and penalties) incurred in connection

from, on an after-tax basis, any Excise Tax, income tax,  employment tax or self
employment tax (including  interest and penalties with respect  thereto) imposed

expenses.  Without  limiting  the  foregoing  provisions  of this Section 7, the
Company shall control all proceedings taken in connection with such contest and,
at its sole  option,  may  pursue or forgo any and all  administrative  appeals,
proceedings,  hearings and conferences  with the taxing  authority in respect of
such claim and may, at its sole option,  either  direct the Executive to pay the
tax claimed and sue for a refund or contest the claim in any permissible manner,
and the Executive agrees to prosecute such contest to a determination before any
administrative  tribunal,  in a court of initial jurisdiction and in one or more
appellate courts,  as the Company shall determine.  The Company's control of the
contest  shall be limited  to issues  with  respect to which a Gross-Up  Payment
would be payable hereunder and Executive shall be entitled to settle or contest,
as the case may be, any other issue  raised by the Internal  Revenue  Service or
any other taxing authority.

         ------------------

          8.1.  Arbitration.  Except as provided  in Section 6.5 hereof,  in the
event that any  disagreement,  dispute,  controversy  or claim arising out of or
relating  to this  Agreement  or the  interpretation  of this  Agreement  or any
arrangements relating to this Agreement or contemplated in this Agreement or the
breach, termination or invalidity thereof (collectively,  a "Dispute") cannot be
resolved by the parties,  and the parties do not agree to an alternate procedure
for  resolving  the Dispute,  the Dispute shall be resolved by final and binding
arbitration,  before  a  panel  of  three  arbitrators  in New  York,  New  York
administered by the American Arbitration  Association ("AAA"). The parties agree
to arbitration  as an alternative to court  proceedings in order (i) to obtain a
prompt  evidentiary  hearing  and an  arbitrator's  final  award  resolving  any
dispute,  (ii) to do so expeditiously,  and (iii) to do so economically.  During
the arbitration proceeding, the arbitrator, in the arbitrator's sole discretion,
shall have the right to grant requests for discovery of documents, the taking of
depositions,  and the issuance of subpoenas in accordance with rules of the AAA.
The Company and the Executive shall each have the right to designate one of such
arbitrators,  and the two  arbitrators  shall together  designate the third such
arbitrator.  The forum for any such  action  shall be New York,  New York.  Each
party  hereby  promises to cooperate in the  arbitration  process to  effectuate
these purposes.  The arbitration shall be conducted in accordance with the rules
of the AAA which are in effect at the time of the arbitration. Judgment rendered
by the arbitrator may be entered in any court having  competent  jurisdiction in
accordance with Delaware law.

          8.2. Waiver of Jury Trial. By submitting a Dispute to arbitration, the
parties hereto understand that they will not enjoy the benefits of a jury trial.
Accordingly, the parties hereto expressly waive the right to a jury trial.

     9.   MISCELLANEOUS
          -------------

          9.1.  Termination  of Merger  Agreement.  In the event that the Merger
Agreement  terminates  prior  to the  Merger,  this  Agreement  shall  thereupon
terminate and be of no further force or effect.

          9.2.  Assignment.  This  Agreement  is personal to the  Executive  and
without  the prior  written  consent of Adecco  shall not be  assignable  by the
Executive  other  than by will or the laws of  descent  and  distribution.  This
Agreement  shall inure to the benefit of and be enforceable  by the  Executive's
legal  representatives.  This  Agreement  shall  inure to the  benefit of and be
binding upon the Company and its successors.  Adecco shall require any successor
to all or  substantially  all of the business  and/or assets of Adecco,  whether
direct or indirect, by purchase, merger, consolidation, acquisition of stock, or
otherwise,  by an agreement in form and substance reasonably satisfactory to the
Executive,  expressly to assume and agree to perform this  Agreement in the same
manner and to the same extent as Adecco  would be required to perform if no such
succession  had taken place.  At the Effective  Time,  this  Agreement  shall be
assumed by, and hereby is assigned to Adecco.

          9.3. Final and Entire Agreement; Amendment. The Executive acknowledges
and agrees that this Agreement  represents the final and entire  agreement among
the parties with respect to the subject matter hereof and, except as provided in
Section 1.3, supersedes all prior agreements (including, without limitation, the
Terminating Prior Agreements),  negotiations and discussions between the parties
hereto  and/or  their  respective  counsel  with  respect to the subject  matter
hereof. Accordingly, except for the rights of the Executive described in Section
1.3(a)  through  (f),  upon the  Company's  fulfilling  its  obligations  to the
Executive  hereunder,  the Executive  agrees that Adecco,  the Company and their
subsidiaries and affiliates shall have no further obligations or liability to or
in respect of the Executive under the Terminating  Prior Agreements or any other
plan, program, agreement or arrangement. This Agreement may be amended, modified
or  changed  only by a written  instrument  executed  by the  Executive  and the
Company,  provided that no such amendment,  modification or change shall be made
prior to the Effective Time without Adecco's prior written consent. No provision
of this  Agreement may be waived  except by a writing  executed and delivered by
the party sought to be charged.  Any such written  waiver will be effective only
with respect to the event or circumstance described therein and not with respect
to any other event or circumstance, unless such waiver expressly provides to the
contrary.

          9.4. Severability and Construction.  In construing this Agreement,  if
any portion of this Agreement shall be found to be invalid or unenforceable, the
remaining  terms and provisions of this  Agreement  shall be given effect to the
maximum extent permitted without  considering the void, invalid or unenforceable
provision. In construing this Agreement,  the singular shall include the plural,
the masculine shall include the feminine and neuter genders as appropriate,  and
no meaning or effect  shall be given to the  captions  of the  sections  in this
Agreement, which are inserted for convenience of reference only.

          9.5.   Consultation  With  Counsel.   The  Executive   represents  and
acknowledges  that he has  discussed  all  aspects  of this  Agreement  with his
attorney  and  that he has  carefully  read  and  fully  understands  all of its
provisions.

          9.6. Expenses. Each of the Company, on one hand, and the Executive, on
the other,  shall be liable for their own respective costs and expenses incident
to the execution of this  Agreement  and the  consummation  of the  transactions
contemplated  hereby.  Should the Executive or his successors retain counsel for
the purpose of  enforcing,  or preventing  the breach of, any  provision  hereof
(including,  but not  limited to, by  instituting  any action or  proceeding  in
arbitration  or court to enforce any  provision  hereof or to enjoin a breach of
any provision of this  Agreement) or for a declaration of such party's rights or
obligations under this Agreement, or any other remedy, whether in arbitration or
in a court of law, then, the Executive shall be entitled to be reimbursed by the
Company for all reasonable  fees and expenses of attorneys and expert  witnesses
and court costs  (including  such fees,  expenses  and costs of appeal),  if the
Executive  prevails  with  respect to a  majority  of his  material  claims in a
nonappealable judgment of a court of competent jurisdiction.

and  its   subsidiaries  in  undertaking  and  preparing  for  legal  and  other
proceedings  relating  to the  affairs  of  Adecco  and  its  subsidiaries.  The
Executive  shall  be  reimbursed  for  the  reasonable  expenses  he  incurs  in
connection with any such cooperation and/or  assistance,  and shall receive from
the Company reasonable per diem compensation in connection  therewith,  such per
diem to be mutually agreed upon by the Executive and the Company.

          9.8.  Notices.  All notices and other  communications  provided to any
party  under this  Agreement  shall be in writing and  delivered  by a reputable
overnight  courier or other  personal  delivery to such party at its address set

by such party in a notice to the other party.  Any notice,  if so delivered  and
properly addressed with postage prepaid, shall be deemed given when received.

          9.9. Withholding.  Adecco or the Company, as applicable,  may withhold
from any amounts payable under this Agreement such federal, state or local taxes
as  shall  be  required  to be  withheld  pursuant  to  any  applicable  law  or
regulation.

          9.10. Unfunded  Obligation.  Except as expressly provided otherwise in
this  Agreement,  the  obligation  to pay  amounts  under this  Agreement  is an
unfunded obligation of the Company,  and no such obligation shall create a trust
or be deemed to be secured  by any  pledge or  encumbrance  on any  property  of
Adecco, the Company or any of their subsidiaries.

          9.11.  Governing  Law.  The  provisions  of this  Agreement  shall  be
construed and  interpreted in accordance  with the internal laws of the State of
New York (without  giving effect to the principles of conflict of laws thereof),
as at the time in effect.

          9.12.  Survival.  The  provisions of Sections 5.1, 5.2, 6.1, 6.2, 6.3,
6.4, 6.5, 7, 8.1, 8.2 and 9.1 through 9.13 shall survive any termination of this
Agreement in accordance with their respective terms.

          9.13.  Counterparts.  This  Agreement  may be  executed in one or more
counterparts,  each of  which  shall  be an  original,  but all of  which  taken
together shall constitute one instrument.

consulting  services for the benefit of Adecco and its  subsidiaries  hereunder,
the  Executive  shall  from  time to time  provide  Adecco,  Adecco's  Board  of
Directors,  and Adecco's  executive officers with such advice as any of them may

each calendar month.  Without limiting the foregoing,  the Executive shall, upon
the reasonable  request of the persons  specified above, (a) consult with Adecco

Adecco in which the  Executive  had  personal  involvement  during his period of
employment and/or directorship with the Company or Adecco, (b) assist Adecco and

subsidiaries'  expense)  as  Adecco  and the  Executive  shall  agree,  and (ii)
negotiate as Adecco's or its subsidiaries' representative when and as reasonably
requested to do so by Adecco's Board of Directors or its executive officers.

the  Executive  is to  act  as a  consultant  and  advisor  to  Adecco  and  its
subsidiaries, and is not an employee or agent of, or co-venturer with, Adecco or
any of its  subsidiaries  in any  respect.  The  Executive  shall have no right,
authority,  or power to act for or on Adecco's behalf other than as described in

dependents)  under the terms of such  plan or plans,  as in effect  from time to
time;  provided,   however,  that,  the  Company's  obligation  hereunder  shall
terminate  upon the date the Executive  becomes  covered under any group medical
plan of the Executive's subsequent employer.

     5.   CONFIDENTIALITY
          ---------------

          5.1.  Confidentiality.  The Executive  acknowledges  that,  during the
course of his employment with the Company, the Executive has had, and during the
course of his engagement under this Agreement the Executive will have, access to
Confidential  Information  (as defined below) owned by the Company and/or Adecco
or used or involved in or incidental to their operations,  business and affairs.
All  such  Confidential  Information  has  been  and  will be  disclosed  to the
Executive  in  confidence.  The  Executive  covenants  that  from and  after the
Effective Time, he (a) will keep  confidential all  Confidential  Information of
Adecco and its  subsidiaries  and affiliates  which is known to him and,  except
with the specific prior written consent of Adecco or as required to be disclosed
by law or the order of any agency, court or other governmental  authority,  will
not disclose any Confidential  Information to any person other than Adecco,  its
subsidiaries and affiliates, or their respective employees accountants,  counsel
and other  designated  representatives  as is  appropriate  in the course of his
consulting  relationship,  and (b)  will not make  any  public  statement  which
disparages  Adecco  or any  of its  subsidiaries  or  any  of  their  respective
employees, officers or directors, which is materially damaging to Adecco and its
subsidiaries  taken as a whole.  For purposes of this  Agreement,  "Confidential
Information"  shall mean all  know-how,  trade  secrets  and other  confidential
nonpublic information prepared for, by or on behalf of, or in the possession of,
the  Company,  Adecco  or any of their  subsidiaries  or  affiliates,  including
without limitation (i) nonpublic proprietary information; (ii) other information
derived  from  reports,  investigations,  research,  studies,  work in progress,
codes, marketing,  sales or service programs, capital expenditure projects, cost
summaries,  equipment,  product or system designs or drawings,  pricing or other
formulae, contract analyses, financial information, projections, agreements with
vendors,  joint venture agreements,  confidential filings with any agency, court
or  other  governmental  authority;  and  (iii)  all  other  concepts,  methods,
techniques and processes of doing  business,  ideas or  information  that can be
used in the  operation  of a business or other  enterprise  and is  sufficiently
valuable, or potentially  valuable,  and secret to afford an actual or potential
economic advantage over others; provided, however, that Confidential Information
shall not include any information that is currently  generally  available to and
generally  known by the public or, through no fault of the Executive,  hereafter
becomes generally available to and generally known by the public.

          5.2. Business Property. All records,  files,  drawings,  documents and
the like relating to Adecco's or the  Company's  business or the business of any
of their  subsidiaries or affiliates  which the Executive shall prepare,  use or
come into contact with, shall be and remain Adecco's sole property and shall not
be removed from the premises of Adecco,  the Company or their  subsidiaries  and
affiliates  without its written  consent except as required in the course of the
Executive's consulting engagement.  Upon the termination of the Consulting Term,
all such  records,  files,  drawings,  documents  and the  like  that are in the
Executive's  custody or control shall  immediately be delivered by the Executive
to Adecco or its designee.  The Executive  acknowledges  that his obligations in
this  Section  are of a unique  character  that  gives  them a special  value to
Adecco,  the loss of which cannot  reasonably or adequately  be  compensated  in
damages in an action at law,  that a breach  thereof will result in  irreparable
and  continuing  harm to Adecco  and its  subsidiaries  and that  therefore,  in
addition  to any other  remedy  that Adecco or the Company may have at law or in
equity,  Adecco and/or the Company shall be entitled to injunctive  relief for a
breach thereof by the Executive.



                                       5

     6.   NONCOMPETITION AND NONSOLICITATION
          ----------------------------------

          6.1. Noncompetition.  The Executive covenants that he will not, during
the  period  commencing  at the  Effective  Time and  terminating  on the fourth
anniversary  of  the  Effective  Time  (the  "Restricted  Period"),  (a)  accept
employment  with or render service to any person,  firm or  corporation  that is
engaged in the  business(es)  conducted by Adecco or any of its  subsidiaries or
affiliates  (as  determined  from time to time) in any market in which Adecco or
any of such subsidiaries or affiliates is then conducting such business(es);  or
(b)  own,  manage,  operate,  or  control,  or  participate  in  the  ownership,
management,  operation,  or control of, or be connected  as a principal,  agent,
representative,   consultant,  advisor,  investor,  owner,  partner,  financier,
contractor,  manager or joint venturer with, or permit his name to be used by or
in connection or  association  with,  any person,  firm or  corporation  that is
engaged in the  business(es)  conducted by Adecco or any of its  subsidiaries or
affiliates  in any  market  in  which  Adecco  or any  of  its  subsidiaries  or
affiliates is then conducting such  business(es);  provided,  however,  that the
Executive may invest as an investor in the voting  securities of any person that
is a reporting company under the Securities Exchange Act of 1934, as amended, so
long as the aggregate  amount of the  securities  the Executive owns directly or
indirectly  is less  than five  percent  (5%) of the  total  outstanding  voting
securities  of that person.  Notwithstanding  anything  contained  herein to the
contrary,  the Executive shall not be prohibited from accepting employment with,
rendering services to or otherwise engaging in any activity or capacity with any
entity  engaged  in the  Health  Services  Business  (as  defined  in the Merger
Agreement).

          6.2. Nonsolicitation. The Executive covenants that he will not, during
the  Restricted  Period,  otherwise  than  on  behalf  of  Adecco  or any of its
subsidiaries  or  affiliates  (as  determined  from time to time),  solicit  the
employment of any person,  or induce or advise any person to leave the employ of
Adecco or any of such  subsidiaries or affiliates,  if such person is, as of the
date of such  solicitation,  inducement  or  advisement,  employed on a full- or
part-time basis by Adecco or any of its subsidiaries or affiliates.

          6.3. Breach by Executive.  Notwithstanding  anything contained herein,
in the  event  that  the  Executive  materially  breaches  any of the  covenants
undertaken by him under Section 6.1 or 6.2, the Company's obligation to make the
compensation   payments  provided  for  in  Section  4.1  or  4.2  hereof  shall
automatically  terminate (other than with respect to any such payments earned by
the Executive  through the date of breach which have not theretofore been paid),
and the Executive shall  automatically  forfeit all of his right to and interest
in such payments.

          6.4.  Modification.   If  the  noncompetition  and/or  nonsolicitation
covenants  contained in the  foregoing  Sections 6.1 and 6.2 are, in the view of
any court or arbitrator  asked to rule upon the issue,  deemed  unenforceable by
reason of  covering  too large an area,  too long a period of time,  too large a
number of  entities  or too many  business  activities,  then the same  shall be
deemed to cover only the largest area, the longest period, the largest number of
entities  or the most  business  activities,  as the case may be,  that will not
render it unenforceable.






                                       6
<PAGE>
          6.5. Specific Performance.  The Executive acknowledges and agrees that
Adecco and the Company cannot be fully or adequately  compensated in damages for
a violation  of Section 6.1 or 6.2  hereof,  and that,  in addition to any other
relief to which Adecco or the Company may be  entitled,  it shall be entitled to
injunctive and equitable relief.

     7.   EXCISE TAX Gross-Up
          -------------------

          (a) Anything in this Agreement to the contrary notwithstanding,  if it
shall  be  determined  that  any  payment,  distribution  (or  benefit  provided
(including, without limitation, the acceleration of any payment, distribution or
benefit  and the  acceleration  of  exercisability  of any stock  option) to the
Executive  or for  his  benefit  (whether  paid or  payable  or  distributed  or
distributable)  pursuant  to the  terms  of this  Agreement  or  otherwise  (the
"Payment")  would be subject,  in whole or in part, to the excise tax imposed by
section 4999 of the Internal  Revenue Code of 1986, as amended (the "Code") (the
"Excise Tax"),  then the Executive shall be entitled to receive from the Company
an additional  payment (the  "Gross-Up  Payment") in an amount such that the net
amount of the Payment and the Gross-Up  Payment  retained by Executive after the
calculation  and  deduction  of all Excise  Taxes  (including  any  interest  or
penalties  imposed  with  respect to such taxes) on the Payment and all federal,
state and local income tax,  employment  tax, self employment tax and Excise Tax
(including any interest or penalties  imposed with respect to such taxes) on the
Gross-Up Payment provided for in this Section 7 and taking into account any lost
or reduced tax deductions on account of the Gross-Up Payment,  shall be equal to
the Payment;

          (b) All  determinations  required  to be made  under  this  Section 7,
including  whether and when the  Gross-Up  Payment is required and the amount of
such  Gross-Up  Payment,  and the  assumptions  to be used in  arriving  at such
determinations  shall be made by the  Accountants (as defined below) which shall
provide  the  Executive,   Adecco  and  the  Company  with  detailed  supporting
calculations with respect to such Gross-Up Payment within ninety (90) days after
the Effective Time. For the purposes of this Section 7, the "Accountants"  shall
mean  PriceWaterhouseCoopers.  For  purposes  of  determining  the amount of the
Gross-Up  Payment,  Executive shall be deemed to pay Federal income taxes at the
applicable  marginal  rate of federal  income  taxation for the calendar year in
which the  Gross-Up  Payment is to be made and to pay any  applicable  state and
local income taxes at the applicable  marginal rate of taxation for the calendar
year in which  the  Gross-Up  Payment  is to be made,  net of the  reduction  in
federal income taxes which could be obtained from the deduction of such state or
local  taxes if paid in such year  (determined  with  regard to  limitations  on
deductions based upon the amount of Executive's  adjusted gross income).  To the
extent  practicable,  any Gross-Up  Payment with respect to any Payment shall be
paid by the Company at the time Executive is entitled to receive the Payment and
in no event  shall any  Gross-Up  Payment  be paid  later than 30 days after the
receipt by the Executive of the Accountants' determination. Any determination by
the Accountants  shall be binding upon the Company and the Executive,  including
for purposes of withholding on amounts payable under this Agreement. As a result
of uncertainty in the application of Section 4999 of the Code at the time of the
initial  determination  by the  Accountants  hereunder,  it is possible that the
Gross-Up  Payment made will have been an amount that is greater or less than the
Company  should  have  paid  pursuant  to this  Section 7 (an  "Overpayment"  or





                                       7
<PAGE>
"Underpayment,"  respectively).  In the  event  that  the  Gross-Up  Payment  is
determined by the Accountants or pursuant to any proceeding or negotiations with
the Internal Revenue Service to be less than the amount initially  determined by
the  Accountants,  the Executive  shall  promptly  repay the  Overpayment to the
Company;  provided,  however,  that in the event  any  portion  of the  Gross-Up
Payment to be repaid to the Company has been paid to any Federal, state or local
tax  authority,  repayment  thereof shall not be required until actual refund or
credit of such  portion  has been made to the  Executive.  In the event that the
Company  exhausts its remedies  pursuant to Section 7 ( c ) and the Executive is
required to make a payment of any Excise Tax, the Underpayment shall be promptly
paid by the Company to or for the Executive's benefit; and

          (c) The  Executive  shall notify  Adecco and the Company in writing of
any claim by the Internal Revenue Service that, if successful, would require the
payment by the Company of the Gross-Up Payment. Such notification shall be given
as soon as practicable  after the Executive is informed in writing of such claim
and shall  apprise  Adecco  and the  Company of the nature of such claim and the
date on which such claim is requested to be paid.  The  Executive  shall not pay
such claim prior to the  expiration of the 30-day  period  following the date on
which the Executive gives such notice to Adecco and the Company (or such shorter
period ending on the date that any payment of taxes,  interest and/or  penalties
with respect to such claim is due).  If the Company  notifies  the  Executive in
writing  prior to the  expiration of such period that it desires to contest such
claim, the Executive shall:

               (i) give the Company any information reasonably requested by
     the Company relating to such claim;

               (ii) take such action in  connection  with  contesting  such
     claim as the Company shall reasonably  request in writing from time to
     time,  including,  without limitation,  accepting legal representation
     with respect to such claim by an attorney  reasonably  selected by the
     Company;

               (iii)  cooperate  with the Company in good faith in order to
     effectively contest such claim; and

               (iv) permit the Company to  participate  in any  proceedings
     relating to such claims;

provided,  however,  that the Company  shall bear and pay directly all costs and
expenses  (including  additional  interest and penalties) incurred in connection
with such contest and shall indemnify  Executive for and hold Executive harmless
from, on an after-tax basis, any Excise Tax, income tax,  employment tax or self
employment tax (including  interest and penalties with respect  thereto) imposed
as a  result  of such  representation  and  payment  of all  related  costs  and
expenses.  Without  limiting  the  foregoing  provisions  of this Section 7, the
Company shall control all proceedings taken in connection with such contest and,
at its sole  option,  may  pursue or forgo any and all  administrative  appeals,
proceedings,  hearings and conferences  with the taxing  authority in respect of
such claim and may, at its sole option,  either  direct the Executive to pay the
tax claimed and sue for a refund or contest the claim in any permissible manner,
and the Executive agrees to prosecute such contest to a determination before any
administrative  tribunal,  in a court of initial jurisdiction and in one or more





                                       8
<PAGE>
appellate courts,  as the Company shall determine.  The Company's control of the
contest  shall be limited  to issues  with  respect to which a Gross-Up  Payment
would be payable hereunder and Executive shall be entitled to settle or contest,
as the case may be, any other issue  raised by the Internal  Revenue  Service or
any other taxing authority.

     8.   DISPUTE RESOLUTION
          ------------------

          8.1.  Arbitration.  Except as provided  in Section 6.5 hereof,  in the
event that any  disagreement,  dispute,  controversy  or claim arising out of or
relating  to this  Agreement  or the  interpretation  of this  Agreement  or any
arrangements relating to this Agreement or contemplated in this Agreement or the
breach, termination or invalidity thereof (collectively,  a "Dispute") cannot be
resolved by the parties,  and the parties do not agree to an alternate procedure
for  resolving  the Dispute,  the Dispute shall be resolved by final and binding
arbitration,  before  a  panel  of  three  arbitrators  in New  York,  New  York
administered by the American Arbitration  Association ("AAA"). The parties agree
to arbitration  as an alternative to court  proceedings in order (i) to obtain a
prompt  evidentiary  hearing  and an  arbitrator's  final  award  resolving  any
dispute,  (ii) to do so expeditiously,  and (iii) to do so economically.  During
the arbitration proceeding, the arbitrator, in the arbitrator's sole discretion,
shall have the right to grant requests for discovery of documents, the taking of
depositions,  and the issuance of subpoenas in accordance with rules of the AAA.
The Company and the Executive shall each have the right to designate one of such
arbitrators,  and the two  arbitrators  shall together  designate the third such
arbitrator.  The forum for any such  action  shall be New York,  New York.  Each
party  hereby  promises to cooperate in the  arbitration  process to  effectuate
these purposes.  The arbitration shall be conducted in accordance with the rules
of the AAA which are in effect at the time of the arbitration. Judgment rendered
by the arbitrator may be entered in any court having  competent  jurisdiction in
accordance with Delaware law.

          8.2. Waiver of Jury Trial. By submitting a Dispute to arbitration, the
parties hereto understand that they will not enjoy the benefits of a jury trial.
Accordingly, the parties hereto expressly waive the right to a jury trial.

     9.   MISCELLANEOUS
          -------------

          9.1.  Termination  of Merger  Agreement.  In the event that the Merger
Agreement  terminates  prior  to the  Merger,  this  Agreement  shall  thereupon
terminate and be of no further force or effect.

          9.2.  Assignment.  This  Agreement  is personal to the  Executive  and
without  the prior  written  consent of Adecco  shall not be  assignable  by the
Executive  other  than by will or the laws of  descent  and  distribution.  This
Agreement  shall inure to the benefit of and be enforceable  by the  Executive's
legal  representatives.  This  Agreement  shall  inure to the  benefit of and be
binding upon the Company and its successors.  Adecco shall require any successor
to all or  substantially  all of the business  and/or assets of Adecco,  whether
direct or indirect, by purchase, merger, consolidation, acquisition of stock, or
otherwise,  by an agreement in form and substance reasonably satisfactory to the
Executive,  expressly to assume and agree to perform this  Agreement in the same
manner and to the same extent as Adecco  would be required to perform if no such
succession  had taken place.  At the Effective  Time,  this  Agreement  shall be
assumed by, and hereby is assigned to Adecco.


                                       9
<PAGE>
          9.3. Final and Entire Agreement; Amendment. The Executive acknowledges
and agrees that this Agreement  represents the final and entire  agreement among
the parties with respect to the subject matter hereof and, except as provided in
Section 1.3, supersedes all prior agreements (including, without limitation, the
Terminating Prior Agreements),  negotiations and discussions between the parties
hereto  and/or  their  respective  counsel  with  respect to the subject  matter
hereof. Accordingly, except for the rights of the Executive described in Section
1.3(a)  through  (f),  upon the  Company's  fulfilling  its  obligations  to the
Executive  hereunder,  the Executive  agrees that Adecco,  the Company and their
subsidiaries and affiliates shall have no further obligations or liability to or
in respect of the Executive under the Terminating  Prior Agreements or any other
plan, program, agreement or arrangement. This Agreement may be amended, modified
or  changed  only by a written  instrument  executed  by the  Executive  and the
Company,  provided that no such amendment,  modification or change shall be made
prior to the Effective Time without Adecco's prior written consent. No provision
of this  Agreement may be waived  except by a writing  executed and delivered by
the party sought to be charged.  Any such written  waiver will be effective only
with respect to the event or circumstance described therein and not with respect
to any other event or circumstance, unless such waiver expressly provides to the
contrary.

          9.4. Severability and Construction.  In construing this Agreement,  if
any portion of this Agreement shall be found to be invalid or unenforceable, the
remaining  terms and provisions of this  Agreement  shall be given effect to the
maximum extent permitted without  considering the void, invalid or unenforceable
provision. In construing this Agreement,  the singular shall include the plural,
the masculine shall include the feminine and neuter genders as appropriate,  and
no meaning or effect  shall be given to the  captions  of the  sections  in this
Agreement, which are inserted for convenience of reference only.

          9.5.   Consultation  With  Counsel.   The  Executive   represents  and
acknowledges  that he has  discussed  all  aspects  of this  Agreement  with his
attorney  and  that he has  carefully  read  and  fully  understands  all of its
provisions.

          9.6. Expenses. Each of the Company, on one hand, and the Executive, on
the other,  shall be liable for their own respective costs and expenses incident
to the execution of this  Agreement  and the  consummation  of the  transactions
contemplated  hereby.  Should the Executive or his successors retain counsel for
the purpose of  enforcing,  or preventing  the breach of, any  provision  hereof
(including,  but not  limited to, by  instituting  any action or  proceeding  in
arbitration  or court to enforce any  provision  hereof or to enjoin a breach of
any provision of this  Agreement) or for a declaration of such party's rights or
obligations under this Agreement, or any other remedy, whether in arbitration or
in a court of law, then, the Executive shall be entitled to be reimbursed by the
Company for all reasonable  fees and expenses of attorneys and expert  witnesses
and court costs  (including  such fees,  expenses  and costs of appeal),  if the
Executive  prevails  with  respect to a  majority  of his  material  claims in a
nonappealable judgment of a court of competent jurisdiction.










                                       10
<PAGE>
          9.7.  Cooperation in Legal Proceedings.  Without limitation of Section
2.2(c)  hereof,  the Executive  agrees,  after the  expiration of the Consulting
Term, upon the reasonable request of Adecco, to cooperate with and assist Adecco
and  its   subsidiaries  in  undertaking  and  preparing  for  legal  and  other
proceedings  relating  to the  affairs  of  Adecco  and  its  subsidiaries.  The
Executive  shall  be  reimbursed  for  the  reasonable  expenses  he  incurs  in
connection with any such cooperation and/or  assistance,  and shall receive from
the Company reasonable per diem compensation in connection  therewith,  such per
diem to be mutually agreed upon by the Executive and the Company.

          9.8.  Notices.  All notices and other  communications  provided to any
party  under this  Agreement  shall be in writing and  delivered  by a reputable
overnight  courier or other  personal  delivery to such party at its address set
forth below its signature  hereto, or at such other address as may be designated
by such party in a notice to the other party.  Any notice,  if so delivered  and
properly addressed with postage prepaid, shall be deemed given when received.

          9.9. Withholding.  Adecco or the Company, as applicable,  may withhold
from any amounts payable under this Agreement such federal, state or local taxes
as  shall  be  required  to be  withheld  pursuant  to  any  applicable  law  or
regulation.

          9.10. Unfunded  Obligation.  Except as expressly provided otherwise in
this  Agreement,  the  obligation  to pay  amounts  under this  Agreement  is an
unfunded obligation of the Company,  and no such obligation shall create a trust
or be deemed to be secured  by any  pledge or  encumbrance  on any  property  of
Adecco, the Company or any of their subsidiaries.

          9.11.  Governing  Law.  The  provisions  of this  Agreement  shall  be
construed and  interpreted in accordance  with the internal laws of the State of
New York (without  giving effect to the principles of conflict of laws thereof),
as at the time in effect.

          9.12.  Survival.  The  provisions of Sections 5.1, 5.2, 6.1, 6.2, 6.3,
6.4, 6.5, 7, 8.1, 8.2 and 9.1 through 9.13 shall survive any termination of this
Agreement in accordance with their respective terms.

          9.13.  Counterparts.  This  Agreement  may be  executed in one or more
counterparts,  each of  which  shall  be an  original,  but all of  which  taken
together shall constitute one instrument.

          2.2.  Nature of  Consulting  and Other  Services.  In his rendering of
consulting  services for the benefit of Adecco and its  subsidiaries  hereunder,
the  Executive  shall  from  time to time  provide  Adecco,  Adecco's  Board  of
Directors,  and Adecco's  executive officers with such advice as any of them may
reasonably  request in connection with the business and operations of Adecco and
its subsidiaries and affiliates. The Executive shall provide such advice only at
the  request of Adecco's  Board of  Directors  or its  executive  officers.  The
Executive  shall hold himself  available at  reasonable  times and on reasonable
notice to render such consulting and advisory  services as may be so assigned to
him by Adecco,  Adecco's  Board of  Directors,  or Adecco's  executive  officers
during the Consulting Term (as defined below);  provided,  however, that, unless
the parties  otherwise agree, the consulting and advisory  services  rendered by
the Executive  during the  Consulting  Term shall not exceed  fifteen (15) hours
each calendar month.  Without limiting the foregoing,  the Executive shall, upon
the reasonable  request of the persons  specified above, (a) consult with Adecco
and its  subsidiaries  with  respect to all  matters  concerning  the Company or
Adecco in which the  Executive  had  personal  involvement  during his period of
employment and/or directorship with the Company or Adecco, (b) assist Adecco and
its  subsidiaries in the negotiation  and  consummation of business  matters and
prospects  pending  at  the  time  of the  termination  of  his  employment  and
thereafter,  and (c) cooperate  with and assist Adecco and its  subsidiaries  in
undertaking  and  preparing  for  legal and other  proceedings  relating  to the
affairs  of Adecco  and its  subsidiaries.  In  connection  with the  consulting
services  rendered by him  hereunder,  the Executive  shall (i)  undertake  such
travel on Adecco's or Adecco's subsidiaries' behalf (and at Adecco's or Adecco's
subsidiaries'  expense)  as  Adecco  and the  Executive  shall  agree,  and (ii)
negotiate as Adecco's or its subsidiaries' representative when and as reasonably
requested to do so by Adecco's Board of Directors or its executive officers.

          2.3.  Nature of Consulting and Other  Services.  It is understood that
the  Executive  is to  act  as a  consultant  and  advisor  to  Adecco  and  its
subsidiaries, and is not an employee or agent of, or co-venturer with, Adecco or
any of its  subsidiaries  in any  respect.  The  Executive  shall have no right,
authority,  or power to act for or on Adecco's behalf other than as described in
Section 2.2 above. The relationship between Adecco and its subsidiaries,  on the
one  hand,  and  the  Executive,  on the  other,  hereunder  shall  be  that  of
independent contractor.

     3.   TERM
          ----

          The  Executive  hereby  agrees  to  provide  the  consulting  services
contemplated  by this Agreement for a term of four (4) years,  commencing at the
Effective Time and  terminating on the fourth  anniversary of the Effective Time
(the "Consulting  Term").  In the event of the death or permanent  disability of
the Executive  after the Effective  Time and prior to the end of the  Consulting
Term, the remaining fees under Sections 4.1 and 4.2 that would have been payable
through the end of the Consulting Term shall continue to be paid through the end
of the  Consulting  Term to the  Executive  or, in the event of the  Executive's
death,  to the  beneficiary  designated in writing by the Executive  (or, in the
absence of a designated  beneficiary  who survives  the  Executive,  Executive's
estate).

Company,  as  applicable,  to its directors  from time to time.  Notwithstanding
anything contained herein, time spent by the Executive in the performance of his
services as a member of Adecco's or the Company's  Board of Directors  shall not
be deemed to be the performance of consulting services hereunder.

dependents)  under the terms of such  plan or plans,  as in effect  from time to

     5.   CONFIDENTIALITY
          ---------------

          5.1.  Confidentiality.  The Executive  acknowledges  that,  during the
course of his employment with the Company, the Executive has had, and during the
course of his engagement under this Agreement the Executive will have, access to
Confidential  Information  (as defined below) owned by the Company and/or Adecco
or used or involved in or incidental to their operations,  business and affairs.
All  such  Confidential  Information  has  been  and  will be  disclosed  to the
Executive  in  confidence.  The  Executive  covenants  that  from and  after the
Effective Time, he (a) will keep  confidential all  Confidential  Information of
Adecco and its  subsidiaries  and affiliates  which is known to him and,  except
with the specific prior written consent of Adecco or as required to be disclosed
by law or the order of any agency, court or other governmental  authority,  will
not disclose any Confidential  Information to any person other than Adecco,  its
subsidiaries and affiliates, or their respective employees accountants,  counsel
and other  designated  representatives  as is  appropriate  in the course of his
consulting  relationship,  and (b)  will not make  any  public  statement  which
disparages  Adecco  or any  of its  subsidiaries  or  any  of  their  respective
employees, officers or directors, which is materially damaging to Adecco and its
subsidiaries  taken as a whole.  For purposes of this  Agreement,  "Confidential
Information"  shall mean all  know-how,  trade  secrets  and other  confidential
nonpublic information prepared for, by or on behalf of, or in the possession of,
the  Company,  Adecco  or any of their  subsidiaries  or  affiliates,  including
without limitation (i) nonpublic proprietary information; (ii) other information
derived  from  reports,  investigations,  research,  studies,  work in progress,
codes, marketing,  sales or service programs, capital expenditure projects, cost
summaries,  equipment,  product or system designs or drawings,  pricing or other
formulae, contract analyses, financial information, projections, agreements with
vendors,  joint venture agreements,  confidential filings with any agency, court
or  other  governmental  authority;  and  (iii)  all  other  concepts,  methods,
techniques and processes of doing  business,  ideas or  information  that can be
used in the  operation  of a business or other  enterprise  and is  sufficiently
valuable, or potentially  valuable,  and secret to afford an actual or potential
economic advantage over others; provided, however, that Confidential Information
shall not include any information that is currently  generally  available to and
generally  known by the public or, through no fault of the Executive,  hereafter
becomes generally available to and generally known by the public.

          5.2. Business Property. All records,  files,  drawings,  documents and
the like relating to Adecco's or the  Company's  business or the business of any
of their  subsidiaries or affiliates  which the Executive shall prepare,  use or
come into contact with, shall be and remain Adecco's sole property and shall not
be removed from the premises of Adecco,  the Company or their  subsidiaries  and
affiliates  without its written  consent except as required in the course of the
Executive's consulting engagement.  Upon the termination of the Consulting Term,
all such  records,  files,  drawings,  documents  and the  like  that are in the
Executive's  custody or control shall  immediately be delivered by the Executive
to Adecco or its designee.  The Executive  acknowledges  that his obligations in
this  Section  are of a unique  character  that  gives  them a special  value to
Adecco,  the loss of which cannot  reasonably or adequately  be  compensated  in
damages in an action at law,  that a breach  thereof will result in  irreparable
and  continuing  harm to Adecco  and its  subsidiaries  and that  therefore,  in
addition  to any other  remedy  that Adecco or the Company may have at law or in
equity,  Adecco and/or the Company shall be entitled to injunctive  relief for a
breach thereof by the Executive.



                                       5
<PAGE>
     6.   NONCOMPETITION AND NONSOLICITATION
          ----------------------------------

          6.1. Noncompetition.  The Executive covenants that he will not, during
the  period  commencing  at the  Effective  Time and  terminating  on the fourth
anniversary  of  the  Effective  Time  (the  "Restricted  Period"),  (a)  accept
employment  with or render service to any person,  firm or  corporation  that is
engaged in the  business(es)  conducted by Adecco or any of its  subsidiaries or
affiliates  (as  determined  from time to time) in any market in which Adecco or
any of such subsidiaries or affiliates is then conducting such business(es);  or
(b)  own,  manage,  operate,  or  control,  or  participate  in  the  ownership,
management,  operation,  or control of, or be connected  as a principal,  agent,
representative,   consultant,  advisor,  investor,  owner,  partner,  financier,
contractor,  manager or joint venturer with, or permit his name to be used by or
in connection or  association  with,  any person,  firm or  corporation  that is
engaged in the  business(es)  conducted by Adecco or any of its  subsidiaries or
affiliates  in any  market  in  which  Adecco  or any  of  its  subsidiaries  or
affiliates is then conducting such  business(es);  provided,  however,  that the
Executive may invest as an investor in the voting  securities of any person that
is a reporting company under the Securities Exchange Act of 1934, as amended, so
long as the aggregate  amount of the  securities  the Executive owns directly or
indirectly  is less  than five  percent  (5%) of the  total  outstanding  voting
securities  of that person.  Notwithstanding  anything  contained  herein to the
contrary,  the Executive shall not be prohibited from accepting employment with,
rendering services to or otherwise engaging in any activity or capacity with any
entity  engaged  in the  Health  Services  Business  (as  defined  in the Merger
Agreement).

          6.2. Nonsolicitation. The Executive covenants that he will not, during
the  Restricted  Period,  otherwise  than  on  behalf  of  Adecco  or any of its
subsidiaries  or  affiliates  (as  determined  from time to time),  solicit  the
employment of any person,  or induce or advise any person to leave the employ of
Adecco or any of such  subsidiaries or affiliates,  if such person is, as of the
date of such  solicitation,  inducement  or  advisement,  employed on a full- or
part-time basis by Adecco or any of its subsidiaries or affiliates.

          6.3. Breach by Executive.  Notwithstanding  anything contained herein,
in the  event  that  the  Executive  materially  breaches  any of the  covenants
undertaken by him under Section 6.1 or 6.2, the Company's obligation to make the
compensation   payments  provided  for  in  Section  4.1  or  4.2  hereof  shall
automatically  terminate (other than with respect to any such payments earned by
the Executive  through the date of breach which have not theretofore been paid),
and the Executive shall  automatically  forfeit all of his right to and interest
in such payments.

          6.4.  Modification.   If  the  noncompetition  and/or  nonsolicitation
covenants  contained in the  foregoing  Sections 6.1 and 6.2 are, in the view of
any court or arbitrator  asked to rule upon the issue,  deemed  unenforceable by
reason of  covering  too large an area,  too long a period of time,  too large a
number of  entities  or too many  business  activities,  then the same  shall be
deemed to cover only the largest area, the longest period, the largest number of
entities  or the most  business  activities,  as the case may be,  that will not
render it unenforceable.






                                       6
<PAGE>
          6.5. Specific Performance.  The Executive acknowledges and agrees that
Adecco and the Company cannot be fully or adequately  compensated in damages for
a violation  of Section 6.1 or 6.2  hereof,  and that,  in addition to any other
relief to which Adecco or the Company may be  entitled,  it shall be entitled to
injunctive and equitable relief.

     7.   EXCISE TAX Gross-Up
          -------------------

          (a) Anything in this Agreement to the contrary notwithstanding,  if it
shall  be  determined  that  any  payment,  distribution  (or  benefit  provided
(including, without limitation, the acceleration of any payment, distribution or
benefit  and the  acceleration  of  exercisability  of any stock  option) to the
Executive  or for  his  benefit  (whether  paid or  payable  or  distributed  or
distributable)  pursuant  to the  terms  of this  Agreement  or  otherwise  (the
"Payment")  would be subject,  in whole or in part, to the excise tax imposed by
section 4999 of the Internal  Revenue Code of 1986, as amended (the "Code") (the
"Excise Tax"),  then the Executive shall be entitled to receive from the Company
an additional  payment (the  "Gross-Up  Payment") in an amount such that the net
amount of the Payment and the Gross-Up  Payment  retained by Executive after the
calculation  and  deduction  of all Excise  Taxes  (including  any  interest  or
penalties  imposed  with  respect to such taxes) on the Payment and all federal,
state and local income tax,  employment  tax, self employment tax and Excise Tax
(including any interest or penalties  imposed with respect to such taxes) on the
Gross-Up Payment provided for in this Section 7 and taking into account any lost
or reduced tax deductions on account of the Gross-Up Payment,  shall be equal to
the Payment;

          (b) All  determinations  required  to be made  under  this  Section 7,
including  whether and when the  Gross-Up  Payment is required and the amount of
such  Gross-Up  Payment,  and the  assumptions  to be used in  arriving  at such
determinations  shall be made by the  Accountants (as defined below) which shall
provide  the  Executive,   Adecco  and  the  Company  with  detailed  supporting
calculations with respect to such Gross-Up Payment within ninety (90) days after
the Effective Time. For the purposes of this Section 7, the "Accountants"  shall
mean  PriceWaterhouseCoopers.  For  purposes  of  determining  the amount of the
Gross-Up  Payment,  Executive shall be deemed to pay Federal income taxes at the
applicable  marginal  rate of federal  income  taxation for the calendar year in
which the  Gross-Up  Payment is to be made and to pay any  applicable  state and
local income taxes at the applicable  marginal rate of taxation for the calendar
year in which  the  Gross-Up  Payment  is to be made,  net of the  reduction  in
federal income taxes which could be obtained from the deduction of such state or
local  taxes if paid in such year  (determined  with  regard to  limitations  on
deductions based upon the amount of Executive's  adjusted gross income).  To the
extent  practicable,  any Gross-Up  Payment with respect to any Payment shall be
paid by the Company at the time Executive is entitled to receive the Payment and
in no event  shall any  Gross-Up  Payment  be paid  later than 30 days after the
receipt by the Executive of the Accountants' determination. Any determination by
the Accountants  shall be binding upon the Company and the Executive,  including
for purposes of withholding on amounts payable under this Agreement. As a result
of uncertainty in the application of Section 4999 of the Code at the time of the
initial  determination  by the  Accountants  hereunder,  it is possible that the
Gross-Up  Payment made will have been an amount that is greater or less than the
Company  should  have  paid  pursuant  to this  Section 7 (an  "Overpayment"  or





                                       7
<PAGE>
"Underpayment,"  respectively).  In the  event  that  the  Gross-Up  Payment  is
determined by the Accountants or pursuant to any proceeding or negotiations with
the Internal Revenue Service to be less than the amount initially  determined by
the  Accountants,  the Executive  shall  promptly  repay the  Overpayment to the
Company;  provided,  however,  that in the event  any  portion  of the  Gross-Up
Payment to be repaid to the Company has been paid to any Federal, state or local
tax  authority,  repayment  thereof shall not be required until actual refund or
credit of such  portion  has been made to the  Executive.  In the event that the
Company  exhausts its remedies  pursuant to Section 7 ( c ) and the Executive is
required to make a payment of any Excise Tax, the Underpayment shall be promptly
paid by the Company to or for the Executive's benefit; and

          (c) The  Executive  shall notify  Adecco and the Company in writing of
any claim by the Internal Revenue Service that, if successful, would require the
payment by the Company of the Gross-Up Payment. Such notification shall be given
as soon as practicable  after the Executive is informed in writing of such claim
and shall  apprise  Adecco  and the  Company of the nature of such claim and the
date on which such claim is requested to be paid.  The  Executive  shall not pay
such claim prior to the  expiration of the 30-day  period  following the date on
which the Executive gives such notice to Adecco and the Company (or such shorter
period ending on the date that any payment of taxes,  interest and/or  penalties
with respect to such claim is due).  If the Company  notifies  the  Executive in
writing  prior to the  expiration of such period that it desires to contest such
claim, the Executive shall:

               (i) give the Company any information reasonably requested by
     the Company relating to such claim;

               (ii) take such action in  connection  with  contesting  such
     claim as the Company shall reasonably  request in writing from time to
     time,  including,  without limitation,  accepting legal representation
     with respect to such claim by an attorney  reasonably  selected by the
     Company;

               (iii)  cooperate  with the Company in good faith in order to
     effectively contest such claim; and

               (iv) permit the Company to  participate  in any  proceedings
     relating to such claims;

provided,  however,  that the Company  shall bear and pay directly all costs and
expenses  (including  additional  interest and penalties) incurred in connection
with such contest and shall indemnify  Executive for and hold Executive harmless
from, on an after-tax basis, any Excise Tax, income tax,  employment tax or self
employment tax (including  interest and penalties with respect  thereto) imposed
as a  result  of such  representation  and  payment  of all  related  costs  and
expenses.  Without  limiting  the  foregoing  provisions  of this Section 7, the
Company shall control all proceedings taken in connection with such contest and,
at its sole  option,  may  pursue or forgo any and all  administrative  appeals,
proceedings,  hearings and conferences  with the taxing  authority in respect of
such claim and may, at its sole option,  either  direct the Executive to pay the
tax claimed and sue for a refund or contest the claim in any permissible manner,
and the Executive agrees to prosecute such contest to a determination before any
administrative  tribunal,  in a court of initial jurisdiction and in one or more





                                       8
<PAGE>
appellate courts,  as the Company shall determine.  The Company's control of the
contest  shall be limited  to issues  with  respect to which a Gross-Up  Payment
would be payable hereunder and Executive shall be entitled to settle or contest,
as the case may be, any other issue  raised by the Internal  Revenue  Service or
any other taxing authority.

     8.   DISPUTE RESOLUTION
          ------------------

          8.1.  Arbitration.  Except as provided  in Section 6.5 hereof,  in the
event that any  disagreement,  dispute,  controversy  or claim arising out of or
relating  to this  Agreement  or the  interpretation  of this  Agreement  or any
arrangements relating to this Agreement or contemplated in this Agreement or the
breach, termination or invalidity thereof (collectively,  a "Dispute") cannot be
resolved by the parties,  and the parties do not agree to an alternate procedure
for  resolving  the Dispute,  the Dispute shall be resolved by final and binding
arbitration,  before  a  panel  of  three  arbitrators  in New  York,  New  York
administered by the American Arbitration  Association ("AAA"). The parties agree
to arbitration  as an alternative to court  proceedings in order (i) to obtain a
prompt  evidentiary  hearing  and an  arbitrator's  final  award  resolving  any
dispute,  (ii) to do so expeditiously,  and (iii) to do so economically.  During
the arbitration proceeding, the arbitrator, in the arbitrator's sole discretion,
shall have the right to grant requests for discovery of documents, the taking of
depositions,  and the issuance of subpoenas in accordance with rules of the AAA.
The Company and the Executive shall each have the right to designate one of such
arbitrators,  and the two  arbitrators  shall together  designate the third such
arbitrator.  The forum for any such  action  shall be New York,  New York.  Each
party  hereby  promises to cooperate in the  arbitration  process to  effectuate
these purposes.  The arbitration shall be conducted in accordance with the rules
of the AAA which are in effect at the time of the arbitration. Judgment rendered
by the arbitrator may be entered in any court having  competent  jurisdiction in
accordance with Delaware law.

          8.2. Waiver of Jury Trial. By submitting a Dispute to arbitration, the
parties hereto understand that they will not enjoy the benefits of a jury trial.
Accordingly, the parties hereto expressly waive the right to a jury trial.

     9.   MISCELLANEOUS
          -------------

          9.1.  Termination  of Merger  Agreement.  In the event that the Merger
Agreement  terminates  prior  to the  Merger,  this  Agreement  shall  thereupon
terminate and be of no further force or effect.

          9.2.  Assignment.  This  Agreement  is personal to the  Executive  and
without  the prior  written  consent of Adecco  shall not be  assignable  by the
Executive  other  than by will or the laws of  descent  and  distribution.  This
Agreement  shall inure to the benefit of and be enforceable  by the  Executive's
legal  representatives.  This  Agreement  shall  inure to the  benefit of and be
binding upon the Company and its successors.  Adecco shall require any successor
to all or  substantially  all of the business  and/or assets of Adecco,  whether
direct or indirect, by purchase, merger, consolidation, acquisition of stock, or
otherwise,  by an agreement in form and substance reasonably satisfactory to the
Executive,  expressly to assume and agree to perform this  Agreement in the same
manner and to the same extent as Adecco  would be required to perform if no such
succession  had taken place.  At the Effective  Time,  this  Agreement  shall be
assumed by, and hereby is assigned to Adecco.


                                       9
<PAGE>
          9.3. Final and Entire Agreement; Amendment. The Executive acknowledges
and agrees that this Agreement  represents the final and entire  agreement among
the parties with respect to the subject matter hereof and, except as provided in
Section 1.3, supersedes all prior agreements (including, without limitation, the
Terminating Prior Agreements),  negotiations and discussions between the parties
hereto  and/or  their  respective  counsel  with  respect to the subject  matter
hereof. Accordingly, except for the rights of the Executive described in Section
1.3(a)  through  (f),  upon the  Company's  fulfilling  its  obligations  to the
Executive  hereunder,  the Executive  agrees that Adecco,  the Company and their
subsidiaries and affiliates shall have no further obligations or liability to or
in respect of the Executive under the Terminating  Prior Agreements or any other
plan, program, agreement or arrangement. This Agreement may be amended, modified
or  changed  only by a written  instrument  executed  by the  Executive  and the
Company,  provided that no such amendment,  modification or change shall be made
prior to the Effective Time without Adecco's prior written consent. No provision
of this  Agreement may be waived  except by a writing  executed and delivered by
the party sought to be charged.  Any such written  waiver will be effective only
with respect to the event or circumstance described therein and not with respect
to any other event or circumstance, unless such waiver expressly provides to the
contrary.

          9.4. Severability and Construction.  In construing this Agreement,  if
any portion of this Agreement shall be found to be invalid or unenforceable, the
remaining  terms and provisions of this  Agreement  shall be given effect to the
maximum extent permitted without  considering the void, invalid or unenforceable
provision. In construing this Agreement,  the singular shall include the plural,
the masculine shall include the feminine and neuter genders as appropriate,  and
no meaning or effect  shall be given to the  captions  of the  sections  in this
Agreement, which are inserted for convenience of reference only.

          9.5.   Consultation  With  Counsel.   The  Executive   represents  and
acknowledges  that he has  discussed  all  aspects  of this  Agreement  with his
attorney  and  that he has  carefully  read  and  fully  understands  all of its
provisions.

          9.6. Expenses. Each of the Company, on one hand, and the Executive, on
the other,  shall be liable for their own respective costs and expenses incident
to the execution of this  Agreement  and the  consummation  of the  transactions
contemplated  hereby.  Should the Executive or his successors retain counsel for
the purpose of  enforcing,  or preventing  the breach of, any  provision  hereof
(including,  but not  limited to, by  instituting  any action or  proceeding  in
arbitration  or court to enforce any  provision  hereof or to enjoin a breach of
any provision of this  Agreement) or for a declaration of such party's rights or
obligations under this Agreement, or any other remedy, whether in arbitration or
in a court of law, then, the Executive shall be entitled to be reimbursed by the
Company for all reasonable  fees and expenses of attorneys and expert  witnesses
and court costs  (including  such fees,  expenses  and costs of appeal),  if the
Executive  prevails  with  respect to a  majority  of his  material  claims in a
nonappealable judgment of a court of competent jurisdiction.

<PAGE>
          9.7.  Cooperation in Legal Proceedings.  Without limitation of Section
2.2(c)  hereof,  the Executive  agrees,  after the  expiration of the Consulting
Term, upon the reasonable request of Adecco, to cooperate with and assist Adecco
and  its   subsidiaries  in  undertaking  and  preparing  for  legal  and  other
proceedings  relating  to the  affairs  of  Adecco  and  its  subsidiaries.  The
Executive  shall  be  reimbursed  for  the  reasonable  expenses  he  incurs  in
connection with any such cooperation and/or  assistance,  and shall receive from
the Company reasonable per diem compensation in connection  therewith,  such per
diem to be mutually agreed upon by the Executive and the Company.

          9.8.  Notices.  All notices and other  communications  provided to any
party  under this  Agreement  shall be in writing and  delivered  by a reputable
overnight  courier or other  personal  delivery to such party at its address set
forth below its signature  hereto, or at such other address as may be designated
by such party in a notice to the other party.  Any notice,  if so delivered  and
properly addressed with postage prepaid, shall be deemed given when received.

          9.9. Withholding.  Adecco or the Company, as applicable,  may withhold
from any amounts payable under this Agreement such federal, state or local taxes
as  shall  be  required  to be  withheld  pursuant  to  any  applicable  law  or
regulation.

          9.10. Unfunded  Obligation.  Except as expressly provided otherwise in
this  Agreement,  the  obligation  to pay  amounts  under this  Agreement  is an
unfunded obligation of the Company,  and no such obligation shall create a trust
or be deemed to be secured  by any  pledge or  encumbrance  on any  property  of
Adecco, the Company or any of their subsidiaries.

          9.11.  Governing  Law.  The  provisions  of this  Agreement  shall  be
construed and  interpreted in accordance  with the internal laws of the State of
New York (without  giving effect to the principles of conflict of laws thereof),
as at the time in effect.

          9.12.  Survival.  The  provisions of Sections 5.1, 5.2, 6.1, 6.2, 6.3,
6.4, 6.5, 7, 8.1, 8.2 and 9.1 through 9.13 shall survive any termination of this
Agreement in accordance with their respective terms.

          9.13.  Counterparts.  This  Agreement  may be  executed in one or more
counterparts,  each of  which  shall  be an  original,  but all of  which  taken
together shall constitute one instrument.
