                               PROSPECTUS SUMMARY
 
    THE  FOLLOWING SUMMARY  IS QUALIFIED  IN ITS  ENTIRETY BY  THE MORE DETAILED
INFORMATION AND CONSOLIDATED  FINANCIAL STATEMENTS AND  NOTES THERETO  APPEARING
ELSEWHERE IN THIS PROSPECTUS AND IN THE DOCUMENTS INCORPORATED BY REFERENCE INTO
THIS PROSPECTUS.
 
                                  THE COMPANY
 
   
    Health  Systems International,  Inc. (the "Company")  is one  of the largest
managed health care companies in the  United States, with more than 1.9  million
full-risk and administrative services only ("ASO") members. The Company provides
a  comprehensive  range  of  health  care  services  through  health maintenance
organizations ("HMOs") located  in the following  four regions: California,  the
Northeast (Connecticut, Pennsylvania and New Jersey), the Northwest (Washington,
Oregon  and Idaho) and the Southwest (Colorado  and New Mexico). Health Net, the
Company's HMO subsidiary in California, with approximately 1.34 million members,
is the second largest provider of managed health care services in the state. The
Company operates  a  preferred  provider  organization  ("PPO")  network,  which
provides  access  to health  care services  to  over 4.6  million persons  in 38
states, and also owns two health  and life insurance companies licensed to  sell
insurance in 33 states and the District of Columbia.
    
 
    The  Company's HMOs market their traditional HMO products to employer groups
and their  Medicare  and Medicaid  products  directly to  eligible  individuals.
Health  care services that are provided to the Company's members include primary
and specialty physician care, hospital care, laboratory and radiology  services,
pharmacy  services,  dental  and  vision care,  skilled  nursing  care, physical
therapy and  mental health  care.  The Company's  HMO service  networks  include
approximately  17,500  primary  care  physicians,  40,500  specialists  and  614
hospitals. The  Company utilizes  sophisticated  medical management  systems  to
reduce  excess  utilization  of  health  care  services.  The  Company  is  also
developing a new medical management system which will utilize clinical protocols
and triage procedures to  direct members to the  most appropriate provider.  The
Company believes that this new system, which it calls "Fourth Generation Medical
Management,"   will  represent   a  major  advance   in  applying  sophisticated
information systems to the practice of medicine.
 
    The Company's  growth  strategy  is focused  on  increasing  enrollment  and
profitability  through  (i) continued  commercial  and Medicare  risk enrollment
expansion  in  existing  markets,  (ii)  membership  and  revenue  growth   from
acquisitions  in  both  new and  existing  markets and  (iii)  improving medical
management of health plans  in new markets and  continued refinement of  medical
management in existing markets. The Company actively seeks to increase growth in
its  existing markets  by increasing  penetration of  its existing  product line
through continued  investment in  its sales  and marketing  capabilities and  by
introducing  new  products that  both increase  plan  flexibility and  reach new
potential customers,  including Medicare  and Medicaid  recipients. The  Company
intends  to expand on its recent success  with its Medicare risk products, which
products have experienced  rapid enrollment  and premium  growth throughout  the
last  three  years. The  Company also  plans  to capitalize  on the  breadth and
quality of its  provider network and  its high quality,  affordable products  to
drive  enrollment growth in  existing markets. The Company  also plans to expand
into contiguous  markets  that  will  allow  it  to  increase  enrollment  while
leveraging its existing infrastructure.
 
    The  Company plans to continue its expansion into geographic areas which the
Company believes represent attractive service markets. The Company believes such
markets have characteristics including relatively  low levels of managed  health
care  and  existing health  care delivery  systems which  can benefit  from more
efficient medical management. The Company  has targeted the Northeastern  United
States  as an  attractive service market  and, in  this regard, in  1995 began a
strategy  of  acquiring  significant  HMO  plans  in  the  Northeast  with   the
acquisition  of  M.D.  Health  Plan,  Inc.  ("M.D.  Health  Plan")  operating in
Connecticut and  Greater  Atlantic  Health Service,  Inc.  ("Greater  Atlantic")
operating  in Pennsylvania and  New Jersey. These  acquisitions, which accounted
for 237,125 members at year end 1995, provide the Company with a platform in the
Northeast  from   which  to   pursue  further   acquisition  and   consolidation
opportunities.  Additionally, the  Company intends to  utilize its sophisticated
medical  management  capabilities  to  optimize  utilization  and  increase  the
profitability of acquired plans.
 
                                       3
<PAGE>
    As  a  result  of  internal  expansion  and  acquisitions,  the  Company has
experienced significant enrollment,  revenue and net  income growth since  1993.
During  this time period, enrollment increased  from 1.3 million to 1.9 million,
revenue increased from $2.0 billion to  $2.7 billion, net income increased  from
$23.8  million to  $89.6 million  and net  income (before  merger-related costs)
increased from $46.1 million to $101.1 million.
 
   
    On April  10,  1996,  the Company  announced  that  it intends  to  take  an
approximately  $34.2 million pre-tax restructuring  charge in its second quarter
ending June 30, 1996, which will be approximately $0.41 per share after-tax. The
charge will cover  computer software  and hardware  write-offs, the  costs of  a
comprehensive  restructuring  of the  Company's  Health Net  subsidiary  and the
consolidation of  certain  operational  functions  of  other  subsidiaries.  The
software  and hardware write-offs are  related to abandoned development projects
at Health Net, which  pre-dated the combination of  QualMed with the Company  in
1994,  and hardware obsolesence. The restructuring  of Health Net will include a
reorganization of its management and  operating structure and staff  reductions.
The Company expects this restructuring to be completed by the end of 1996.
    
 
   
    On May 7, 1996 the Company announced its principal results of operations for
the  quarter ended March 31, 1996. Revenues increased 27.7% from $627 million in
the first quarter of 1995 to $801 million in the first quarter of 1996.  Primary
earnings  per  share increased  10.2% from  $.49  in the  first quarter  of 1995
(before merger-related  costs) to  $.54  in the  first  quarter of  1996.  Total
enrollment  increased by approximately  178,000, or 10.2%, since  the end of the
first quarter of 1995 to approximately  1,918,000 commercial and ASO members  as
of  March 31,  1996. Medicare enrollment  increased 51% during  this period with
acquired plans adding approximately 87,000 members. Total enrollment as of March
31, 1996 decreased by approximately 20,000 from December 31, 1995. A decrease in
commercial membership of approximately 41,000 was partially offset by  increases
of  approximately 7,000 in Medicare membership, approximately 10,000 in Medicaid
membership and approximately 4,000 in ASO membership.

           CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
 
    Certain  statements contained under "Management's Discussion and Analysis of
Financial Condition and  Results of Operations,"  such as statements  concerning
future  premium rates  and the Company's  ability to control  health care costs,
certain statements  contained under  "Business," such  as statements  concerning
proposed  efforts to control health care and administrative costs and the future
of the health  care industry,  and other statements  contained herein  regarding
matters  that are not  historical facts are  forward-looking statements (as such
term is  defined in  the Securities  Act of  1933, as  amended (the  "Securities
Act")). Because such forward-looking statements include risks and uncertainties,
actual  results may differ materially from those expressed in or implied by such
forward-looking statements. Factors  that could cause  actual results to  differ
materially  include, but are not limited  to, those discussed herein under "Risk
Factors."
 
                                  RISK FACTORS
 
CONTROL OVER AND PREDICTABILITY OF HEALTH CARE COSTS
 
    The Company's profitability depends in large part upon accurately predicting
health care costs  and upon  its ability to  control health  care costs  through
underwriting  criteria,  utilization  management  and  negotiation  of favorable
provider  contracts.  The  aging  of   the  population  and  other   demographic
characteristics  and advances  in medical  technology continue  to contribute to
rising  health  care  costs.  Government-imposed  limitations  on  Medicare  and
Medicaid  reimbursement have  also caused the  private sector to  bear a greater
share of health  care costs. Changes  in health care  practices, inflation,  new
technologies, major epidemics, disasters and catastrophes, clusters of high-cost
cases  and numerous other factors affecting the delivery and cost of health care
are beyond any  health plan's  control and  may adversely  affect the  Company's
ability  to predict and control health care costs and claims. In addition, there
can be no assurance that provider  agreements negotiated in the future will  not
result  in substantially higher health  care costs. See "Management's Discussion
and Analysis of  Financial Condition and  Results of Operations  -- Health  Care
Expenses."
 
HEALTH CARE REFORM LEGISLATION
 
    As a result of the escalation of health care costs and the inability of many
individuals  and  employers  to  obtain  affordable  health  insurance, numerous
proposals have been,  and may continue  to be, introduced  in the United  States
Congress  and  state legislatures,  and  other proposals  are  being considered,
relating to  health care  reform. Among  the proposals  under consideration  are
price   controls  on  hospitals,  insurance   market  reforms  to  increase  the
availability of group  health insurance to  small businesses, requirements  that
all  businesses offer health insurance coverage to their employees, the creation
of a government health  insurance plan or plans  that would cover all  citizens,
mandated  health plan benefits, mandated provider payment arrangements and other
proposals involving various aspects of plan operations. The Company is not  able
to evaluate whether any of such proposals or other proposals will be adopted and
implemented.  However,  certain  of  the proposals,  if  adopted,  could  have a
material adverse effect on the  Company's business. See "Business --  Government
Regulation."
 
GOVERNMENT REGULATION
 
    The health care industry in general, and HMOs and health insurance companies
in  particular,  are  subject  to  substantial  federal  and  state  regulation,
including, but not limited to, regulation relating to cash reserves, minimum net
worth,  licensing  requirements,  approval  of  policy  language  and  benefits,
mandatory  products  and benefits,  provider compensation  arrangements, premium
rates and periodic  examinations by  state and federal  agencies. The  Company's
ability  to declare and pay dividends is also limited by state regulations which
restrict the Company's subsidiaries' ability to distribute funds to the Company.
In addition, many states in which the Company operates are currently considering
regulation relating to  mandatory benefits, provider  compensation, any  willing
provider  legislation and composition of  physician networks. Changes in federal
and state laws or regulations, if enacted, could increase health care costs  and
administrative  expenses,  and changes  could be  made  in Medicare  or Medicaid
reimbursement rates. There can be no
 
                                       6
<PAGE>
assurance that any future regulatory action by such other governmental  agencies
will  not have an  adverse impact on  the profitability or  marketability of the
Company's plans in their respective jurisdictions. See "Business -  Governmental
Regulation."
 
COMPETITION AND PREMIUM PRICING
 
    The   managed  health  care  industry  is  highly  competitive,  with  major
competitors including Blue  Cross/ Blue Shield  plans, other indemnity  insurers
and other national and regional HMOs, PPOs and third party administrator ("TPA")
companies.  A number  of the Company's  competitors are more  established in the
health care  industry  and have  substantially  larger memberships  and  greater
financial  resources  than the  Company.  Additional competitors  may  enter the
Company's markets in the  future. The Company  anticipates that premium  pricing
will  be highly competitive and  the Company may not  be able to secure adequate
premium pricing. In the last two fiscal years, the California commercial  market
has  experienced premium rate decreases due, in large part, to premium reduction
initiatives undertaken by large employer groups. The Company believes that there
will continue  to  be premium  reduction  pressures on  HMOs  from  increasingly
sophisticated  consumers,  such as  large employer  groups, particularly  in the
California commercial marketplace. Due  to these competitive pricing  pressures,
the Company does not believe that its California commercial membership will grow
significantly  in 1996. See  "Management's Discussion and  Analysis of Financial
Condition and Results of Operations" and "Business -- Competition."
 
ACQUISITIONS AND GROWTH
 
    A significant part of the Company's  business strategy is to diversify  into
new   geographic   markets  through   acquisitions.  Identifying   and  pursuing
acquisition opportunities, integrating acquired  businesses and managing  growth
requires a significant amount of management time and skill. Although the Company
is  currently  reviewing and  contemplating the  acquisition  of HMOs  and other
health  care-related   entities,   there   are  currently   no   agreements   or
understandings  regarding any such transactions. There  can be no assurance that
the Company  will  be able  to  (i)  negotiate acceptable  terms  with  suitable
acquisition  candidates or that, if negotiated, such acquisitions will be either
approved by all relevant regulatory authorities or consummated, (ii)  assimilate
such acquired companies or (iii) manage future growth.
 
    The  Company also actively seeks to  increase growth in its existing markets
by increasing  penetration  of  its  existing  product  line  through  continued
investment  in  its  sales and  marketing  capabilities and  by  introducing new
products that both increase plan  flexibility and reach new potential  customers
including  Medicare and Medicaid recipients. There  can be no assurance that the
Company will be able to successfully implement this strategy as the introduction
of new products may be subject to unforeseen costs and regulatory delays.
 
POTENTIAL LITIGATION
 
    The Company,  like  HMOs and  health  insurers generally,  excludes  certain
health  care  services from  coverage under  its  plans. The  Company is  in its
ordinary course of business subject to  the claims of its enrollees arising  out
of  decisions to  restrict treatment  or to  restrict reimbursement  for certain
services. The loss of any such claim, if it results in a significant punitive or
other damage award or a directive that the Company effect significant changes in
its operations,  could  have  a  material adverse  effect  on  the  Company.  In
addition,  the risk  of potential liability  under punitive  damage theories may
increase significantly  the difficulty  of obtaining  reasonable settlements  of
coverage  claims. There can be no  assurance that successful claims of enrollees
will not have a material adverse effect on the Company's business.
 
VOLATILITY OF STOCK PRICE
 
    The trading price of the Class A Common Stock may be subject to fluctuations
in response to variations in quarterly operating results, general trends in  the
health  care market,  regulatory developments,  general economic  conditions and
other factors.

                                  THE COMPANY
 
    The Company was incorporated  in 1990. The Company  is the successor to  the
business  conducted by Health Net,  which became a subsidiary  of the Company in
1992, and the HMOs and PPO networks operated by QualMed, which combined with the
Company in 1994 (the "HSI Combination").  The Company operates and conducts  its
HMO  and other  businesses through its  wholly and  majority owned subsidiaries.
Except as  the context  otherwise requires,  the term  the "Company"  refers  to
Health Systems International, Inc. and its subsidiaries.
 
    The  Company's  principal  executive  offices are  located  at  21600 Oxnard
Street, Woodland Hills, California 91367, telephone (818) 719-6978 and 225 North
Main Street, Pueblo, Colorado 81003, telephone (719) 542-0500.
 
                                USE OF PROCEEDS
 
   
    The net  proceeds  to be  received  by the  Company  from the  sale  of  the
3,194,374 shares of Class A Common Stock offered by the Company are estimated to
be  $      million, after deducting  underwriting discounts  and commissions and
estimated expenses of the Offering payable  by the Company. The Company  intends
to  use all of the  net proceeds to the Company  from the Offering to repurchase
3,194,374 shares of Class A Common Stock currently held pursuant to the  Amended
and  Restated Health Net Trust Agreement dated as of May 1, 1994 (the "Associate
Trust Agreement"), on behalf of certain founding stockholders of the Company  at
the  date of  the Conversion (the  "Class A Stockholders").  The Associate Trust
Agreement was  initially entered  into  in connection  with the  Conversion  and
imposes  strict restrictions on the ability of  the Class A Stockholders to sell
or otherwise transfer shares  of Class A Common  Stock held under the  Associate
Trust to any entity other than the Company (except in certain limited instances)
prior  to February 28,  1997. The repurchase price  per share to  be paid by the
Company to repurchase these shares of Class A Common Stock will be equal to  the
net proceeds per share received by the Company in the Offering.
    
 
   
    The  Company will not receive any of the proceeds from the sale of shares of
Class A Common Stock by the Selling Stockholder.

                                DIVIDEND POLICY
 
   
    No  dividends have been paid by the  Company during the preceding two fiscal
years. The  Company has  no present  intention of  paying any  dividends on  its
Common  Stock. The Company is  a holding company and,  therefore, its ability to
pay dividends depends on distributions received from its subsidiaries, which are
subject to  regulatory  net  worth requirements  and  certain  additional  state
regulations  which may restrict the declaration of dividends by licensed managed
health care plans and insurance companies. The payment of any dividend is at the
discretion of the Company's  Board of Directors and  depends upon the  Company's
earnings, financial position, capital requirements and such other factors as the
Company's  Board of Directors  deems relevant. In  addition, the Credit Facility
(as defined herein) restricts the Company's ability to declare or pay  dividends
to  its stockholders or to  purchase, redeem or otherwise  acquire shares of its
capital stock.

    The following  table  sets  forth the  consolidated  capitalization  of  the
Company  as of December 31, 1995 on an  actual basis. All of the net proceeds to
the Company from the Offering will be used by the Company to repurchase the same
number of shares of Class A Common Stock that the Company sells in the Offering.
The Offering will have  no impact on the  capitalization of the Company,  except
that  after  the  Offering,  27,548,527  shares  of  Class  A  Common  Stock and
20,547,322 shares  of Class  B Common  Stock will  be outstanding.  See "Use  of
Proceeds."

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
   
RECENT DEVELOPMENTS
    
 
   
    On May 7, 1996 the Company announced its principal results of operations for
the  quarter ended March 31, 1996. Revenues increased 27.7% from $627 million in
the first quarter of 1995 to $801 million in the first quarter of 1996.  Primary
earnings  per  share increased  10.2% from  $.49  in the  first quarter  of 1995
(before merger-related  costs) to  $.54  in the  first  quarter of  1996.  Total
enrollment  increased by approximately  178,000, or 10.2%, since  the end of the
first quarter of 1995 to approximately  1,918,000 commercial and ASO members  as
of  March 31,  1996. Medicare enrollment  increased 51% during  this period with
acquired plans adding approximately 87,000 members. Total enrollment as of March
31, 1996 decreased by approximately 20,000 from December 31, 1995. A decrease in
commercial membership of approximately 41,000 was partially offset by  increases
of  approximately 7,000 in Medicare membership, approximately 10,000 in Medicaid
membership and approximately 4,000 in ASO membership.
    
 
   
    On April  10,  1996,  the Company  announced  that  it intends  to  take  an
approximately  $34.2 million pre-tax restructuring  charge in its second quarter
ending June 30, 1996, which will be approximately $0.41 per share after-tax. The
charge will cover  computer software  and hardware  write-offs, the  costs of  a
comprehensive  restructuring  of the  Company's  Health Net  subsidiary  and the
consolidation of certain operational functions of other subsidiaries.
    
 
   
    The software and  hardware write-offs are  related to abandoned  development
projects  at  Health  Net, which  pre-dated  the HSI  Combination,  and hardware
obsolesence. The restructuring of  Health Net will  include a reorganization  of
its management and operating structure and staff reductions. The Company expects
this restructuring to be completed by the end of 1996.
    
 
   
GENERAL
    
 
    Since  the  HSI Combination  in January  1994,  the Company  has experienced
significant growth in both revenue and profitability. Revenue increased to  $2.7
billion  in 1995, from $2.3 billion in 1994 and $1.9 billion in 1993, net income
reached $89.6 million in 1995, up from  $88.1 million in 1994 and $23.8  million
in 1993 and net income (before merger-related costs) increased to $101.1 million
in  1995, up from $88.5 million in 1994 and $46.1 million in 1993. In 1995, with
continued commercial  premium  rate pressures  in  California, the  Company  has
focused  on increasing  its presence in  the Medicare market  in California and,
through  strategic  acquisitions,  entering  new  geographic  markets.  Medicare
membership  grew  by 69%  in  1995 and  50%  in 1994.  As  initial steps  in its
Northeast expansion plan, the Company in March 1995 acquired M.D. Health Plan, a
managed health  care company  operating  in the  State  of Connecticut,  and  in
December 1995 acquired Greater Atlantic, a managed health care company operating
in Pennsylvania and New Jersey.
 
    Revenue  growth  in  1995  and  1994  has been  due  in  large  part  to the
significant increases in Medicare risk  membership, accounting for $191  million
of  the $402 million premium revenue increase in 1995 over 1994. The majority of
this increase occurred in  the Company's California  market, where the  Medicare
risk  product  was initially  offered in  1993. The  remaining 1995  increase in
premium revenue was a result of the Company's expansion into the Northeast.  The
acquisition of M.D. Health Plan initially added 59,000 commercial members, which
increased   to  117,000  by  year  end,  primarily  due  to  the  conversion  of
approximately 52,000  State  of Connecticut  employees  from ASO  to  full  risk
membership  in July 1995. The Company  subsequently acquired Greater Atlantic, a
90,000 member  HMO  with operations  in  Pennsylvania and  New  Jersey.  Greater
Atlantic's  business  includes a  substantial  number of  Medicare  and Medicaid
members. Together,  those  acquisitions  contributed  $173  million  in  premium
revenue  in 1995. Medicare risk membership  growth accounted for $137 million of
the $347 million premium  revenue increase in 1994  over 1993. The remainder  of
the  1994 increase was  primarily due to increase  in commercial HMO membership,
which again occurred primarily  in the California  market. The Company  believes
that  commercial  premium  rate  pressures,  particularly  in  California,  will
continue in 1996 and,  accordingly, the Company will  continue to emphasize  the
growth  of  its  Medicare  risk business  and  expansion  into  other geographic
markets. In addition, the  Company is developing  products designed to  increase
its presence in the middle and small group California markets.
 
    Effective  medical management and the recontracting of its largely capitated
provider network in  California have enabled  the Company to  maintain a  stable
MLR, despite industry premium pressures. The
 
                                       12
<PAGE>
Company's  overall MLR increased slightly  to 81.0% in 1995  from 80.3% in 1994,
primarily due to  the increased Medicare  risk business in  1995. Medicare  risk
MLRs  typically run higher than commercial  ratios due to the higher utilization
of services  in the  senior population.  A stable  commercial MLR  of 79.4%  was
achieved  by  the Company  in 1995  by renegotiating  its provider  contracts in
California to  offset premium  pricing pressures  and quickly  implementing  its
medical management system in its newly acquired HMO operations in the Northeast.
 
    Declining   marketing,  general   and  administrative   expenses  (excluding
merger-related costs and ASO business) as  a percentage of premium revenue  over
the  period of 1993 through 1995  (13.5%, 11.6% and 11.2%, respectively) reflect
the Company's  ongoing efforts  to  control costs  and increase  its  membership
growth  in the higher  premium Medicare business.  Merger-related costs of $20.2
million incurred in 1995  resulted from the  proposed business combination  (the
"HSI/WellPoint  Transaction") with  WellPoint Health  Networks Inc.  and certain
commercial operations of Blue Cross of California that was ultimately abandoned.

PREMIUM REVENUE
 
    Premium revenue, excluding ASO revenues, increased by $402 million or  17.5%
from  1994 to 1995, and by $347 million  or 17.8% from 1993 to 1994. The factors
that  contributed  to  the  1995  increase  over  1994  included  Medicare  risk
membership  gains, acquisitions completed in 1995 in the Northeast and continued
growth in  commercial  membership  in  the  Company's  existing  service  areas.
Increased  membership, particularly in  higher premium Medicare  business and in
the Northeast, was offset in part  by premium rate reductions in the  California
commercial  market. The factors that contributed  to the 1994 increase over 1993
included Medicare risk membership gains and membership growth in the  commercial
business, particularly in California.
 
    The  acquisitions  in  the  Northeast contributed  $173  million  in premium
revenue in 1995. Premium revenue increases in the Company's existing markets are
attributable to a combination of membership
 
                                       13
<PAGE>
increases and premium rate  changes. Increases in  commercial and Medicare  risk
membership  accounted for $316 million of premium revenue increases in 1995 from
1994. Commercial membership increases accounted for $145 million of the increase
and Medicare risk membership increases accounted for $171 million. Premium  rate
decreases  in the commercial business resulted  in a decrease in premium revenue
of $100  million in  1995  and increases  in  Medicare rates  increased  premium
revenue  by $13 million in 1995.  The commercial premium rate decreases occurred
primarily in  California's  large  employer group  base,  where  organized  rate
reduction  initiatives  by  large  employer  groups  have  been  undertaken. The
Medicare premium  rate increases  reflect  average Medicare  reimbursement  rate
increases of 4.6% in 1995. On a per member per month ("PMPM") basis, the premium
rate  changes resulted in  a decrease of  3.0% in commercial  premium revenue to
$118.51 and an increase in Medicare premium revenue of 4.5% to $394.42 in  1995.
Overall,  Medicare risk  business accounted for  an increase of  $191 million of
premium revenue  in 1995  over 1994  and commercial  business accounted  for  an
increase of $211 million of premium revenue in 1995 over 1994.
 
    Increases  in  commercial and  Medicare risk  membership accounted  for $335
million of premium revenue increases in  1994 from 1993. Of this increase,  $190
million  represented commercial  membership increases and  $145 million resulted
from Medicare risk membership  increases. Changes in premium  rates in both  the
commercial  business and Medicare risk business accounted for an increase of $12
million of premium revenue in  1994. On a PMPM  basis, the premium rate  changes
resulted  in an increase of 1.1% in  commercial premium revenue to $122.17 and a
decrease in Medicare premium revenue of 4.5% to $377.33 in 1994. The decrease in
the Medicare PMPM revenue reflected the growth of the Company's senior plans  in
areas  with lower Medicare reimbursement  rates. Overall, Medicare risk business
accounted for an increase of $137 million of premium revenue in 1994 compared to
1993 and  commercial business  accounted  for an  increase  of $210  million  of
premium revenue in 1994 compared to 1993.
 
    The  aforementioned  premium rate  decreases in  the California  market have
been, in large part, the result  of premium reduction initiatives undertaken  by
large  employer groups. On June 20, 1994,  the Bay Area Business Group on Health
("BBGH"), a  consortium  of 19  large  California employers  which  collectively
provides  health care benefits for 300,000 employees through HMOs in California,
announced premium rate  reductions on  behalf of eleven  BBGH member  companies.
Similarly,  in early  1995, Health  Net submitted  a proposal  to the California
Public Employees  Retirement System  ("CalPERS") for  a rate  reduction for  the
CalPERS  1995  to 1996  fiscal  year. CalPERS  is  the Company's  single largest
employer group  with approximately  133,000  members at  December 31,  1995  and
110,000 members at December 31, 1994. CalPERS accepted Health Net's proposal for
a  7.2% rate decrease  for its 1995  to 1996 fiscal  year from its  1994 to 1995
fiscal year rates. In  1995, BBGH expanded to  include large employer groups  in
other  western states and was renamed the  Pacific Business Group on Health (the
"Pacific Business Group"). Similar rate reductions were also submitted to  other
large  employer groups in 1995. Management of  the Company believes that in 1996
there  will  continue  to  be  premium  pressures  on  HMOs  from   increasingly
sophisticated  consumers  such  as  the  Pacific  Business  Group  and  CalPERS,
particularly in the  California marketplace.  Due to  these competitive  pricing
pressures,   the  Company  does  not  believe  that  its  California  commercial
membership will grow significantly in 1996.
 
    The Company's ASO business accounted for  $39.7 million in revenue in  1995,
contributing  $15.6 million and  $13.5 million to overall  revenues for 1994 and
1993, respectively. The Company anticipates  continuing increases from such  TPA
services  as a result of growth in  its non-risk PPO product, increased business
in its Comp-24 workers' compensation product,  as well as ASO business  acquired
in connection with HMO acquisitions.
 
HEALTH CARE EXPENSES
 
    Through   the  execution   of  various  medical   management  incentive  and
cost-containment programs  that  have  been established  with  its  networks  of
providers and the implementation of effective utilization management systems and
information  systems that provide timely and accurate medical outcomes data, the
Company has been able to contain health care expense increases, particularly  in
its  commercial business, where the MLR has  remained stable over the past three
years.
 
    Health care expenses increased by $342 million, or 18.6%, to $110.23 PMPM in
1995 compared  to $107.82  PMPM in  1994. The  Company's overall  MLR  increased
slightly  to 81.0%  from 80.3% in  1994. Impacting the  Company's overall health
care  expense   PMPM   and   MLR   was   the   growth   in   Medicare   business
 
                                       14
<PAGE>
and  the associated  higher utilization. In  addition, the Company's  MLR in the
Medicare risk business  increased to 88.0%  in 1995  from 85.6% in  1994 due  to
Medicare  risk membership  growth in higher  cost areas.  Commercial health care
expenses on a PMPM basis decreased from $97.03 in 1994 to $94.09 in 1995 and the
Company's commercial MLR remained flat in 1995, at 79.4%, relative to 1994.  The
Company's  recontracting in  1995 of  its largely  capitated commercial provider
network in  California enabled  it  to maintain  its relatively  consistent  MLR
despite the reduced commercial premium rates experienced in that market in 1995.
The  implementation  of the  Company's medical  management  system in  its newly
acquired HMO operations  in the Northeast  also contributed to  the stable  1995
MLR.  Significant and ongoing cost savings  have been achieved through effective
utilization management in the Company's Connecticut operations.
 
    Healthcare expenses increased by $271 million, or 17.3%, to $107.82 PMPM  in
1994  compared  to $103.71  PMPM in  1993. The  Company's overall  MLR decreased
slightly to 80.3% from 80.6% in 1993. Commercial healthcare expenses were stable
in terms of both MLR and on a PMPM basis. The commercial MLR decreased to  79.4%
compared  to 79.9%  in 1993. Medicare  healthcare expenses decreased  in 1994 to
$323.14 PMPM from $347.34 PMPM in 1993.  The Medicare MLR decreased to 85.6%  in
1994  from 87.9% in  1993. The improvement  in Medicare health  care expenses in
1994 compared to 1993 was due to economies of scale and disproportionate  growth
in lower cost areas.
 
MARKETING, GENERAL AND ADMINISTRATIVE EXPENSES
 
    Marketing,  general and administrative expenses  (excluding ASO expenses and
costs associated  with the  HSI/Wellpoint Transaction)  were $302.9  million  or
11.2% of premium revenue in 1995, compared to $266.8 million or 11.6% of premium
revenue  in  the  prior  year. Marketing,  general  and  administrative expenses
(excluding ASO expenses) were $266.8 million,  11.6% of premium revenue in  1994
compared  to  $262.9  million,  or 13.5%  of  premium  revenue  (excluding costs
associated with  the  HSI Combination)  in  the  prior year.  The  decreases  in
marketing, general and administrative expenses from 1993 to 1995 reflect ongoing
efforts to streamline operations and maximize efficiencies.
 
DEPRECIATION AND AMORTIZATION EXPENSES
 
    Depreciation  and amortization expenses  as a percentage  of premium revenue
increased slightly from 1.7% in 1994 to 1.8% in 1995 ($39.7 million in 1994  and
$48.1  million in 1995). The increase  in depreciation and amortization expenses
resulted primarily from the goodwill recorded in connection with the M.D. Health
Plan and Greater Atlantic acquisitions.
 
MERGER-RELATED COSTS
 
    Throughout 1995, the Company incurred merger-related costs of $20.2  million
in  connection with the  proposed HSI/WellPoint Transaction  that was ultimately
terminated. Such  costs  included legal,  accounting  and consulting  fees,  and
certain severance-related costs totaling $12.2 million.
 
    The  Company accrued  certain fees and  expenses in connection  with the HSI
Combination totaling $29.7 million which  are reflected as merger-related  costs
in the Company's 1993 consolidated statement of income.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company's primary source of cash is premium revenue. Its primary uses of
cash  are claims and capitation payments. Estimates of future cash flows include
a component to  account for  the delay  between providing  medical services  and
reporting  their cost.  These estimates  are based  on actuarial  projections of
claims and  other  costs, claims  paid  history, membership  growth,  inflation,
seasonality, claims inventory and reserves.
 
    The  Company's capital resources are managed according to certain guidelines
intended to  ensure  liquidity and  maximum  total return  by  assuming  prudent
investment  risks. The Company's  liquidity requirements consist  of the need to
service medical claims in a timely manner  and to satisfy shared risk and  other
obligations.  Such  requirements are  the principal  factors in  determining the
appropriate investment portfolio mix. The Company presently invests primarily in
a variety  of  fixed  income obligations  according  to  established  investment
guidelines.
 
                                       15
<PAGE>
    For  the year ended December 31, 1995, cash provided by operating activities
decreased to $111.6 million from $160.8 million in the prior year. This decrease
is due primarily to fluctuations in  operating assets and liabilities from  year
to  year  caused by  timing  differences in  the  collection of  receivables and
payment of liabilities at each respective  year end. Net cash used by  investing
activities  approximated  $282  million in  1995,  primarily the  result  of the
acquisition of the M.D. Health Plan and  Greater Atlantic and a net increase  in
the purchase of marketable securities held for sale. The financing of these 1995
acquisitions was through additional borrowing on the Credit Facility.
 
    Outstanding  notes payable amounted to $356.4  million at December 31, 1995,
resulting primarily from additional borrowings  related to the M.D. Health  Plan
and  Greater Atlantic acquisitions. Principal and interest requirements of notes
payable are scheduled at  between $17 million and  $25 million per year  through
2006.
 
    Management  of  the  Company  believes that  its  cash  from  operations and
existing working capital  are adequate to  fund existing obligations,  introduce
new   products  and  services  and  continue  to  develop  health  care  related
businesses. The  Company  regularly  evaluates  cash  requirements  for  current
operations,  commitments, development activities and strategic acquisitions. The
Company may elect to raise additional  funds for these purposes, either  through
the  issuance of  additional debt  or equity,  sale of  investment securities or
otherwise, as appropriate.
 
   
    On April 12, 1995, the Company  obtained a five year unsecured $400  million
revolving  line of credit from  a lending syndicate led  by Bank of America (the
"Credit Facility"). The Company used $310 million of the Credit Facility to fund
the prepayment by  its Health  Net subsidiary  of $135  million in  debt to  the
Selling  Stockholder,  and to  fund the  M.D. Health  Plan and  Greater Atlantic
acquisitions in the amount of $100 million and $75 million, respectively.  Under
the  Credit Facility, the Company  may incur permitted subordinated indebtedness
in a maximum aggregate amount not to exceed $150 million which will be available
for acquisition  purposes  and to  provide  short-term financing  to  repurchase
shares  of stock. Under the terms of the  Credit Facility, the Company is to pay
interest at a variable  rate based upon  a spread above the  LIBOR rate, or  the
greater  of the bank's reference  rate or the federal  funds rate plus 1/2%. The
Company may elect a "competitive bid  auction" in which participating banks  are
offered  an opportunity to bid  alternative rates. The Credit  Facility is for a
term of five  years from  the date  of execution,  with two  one year  extension
options.  See Note 5 to the consolidated financial statements included elsewhere
in this Prospectus.  On April  26, 1996,  the amount  of the  revolving line  of
credit available under the Credit Facility was increased to $700 million and the
initial  five year  term was  extended to April  26, 2001.  On May  8, 1996, the
Company obtained a waiver from the lending syndicates, pursuant to an  amendment
to the Credit Facility, to permit the Company to repurchase more than 50% of its
shares  beneficially owned  by certain  Class A  Stockholders, certain  of which
shares are to be repurchased  by the Company with  the proceeds received by  the
Company from the Offering.
    
 
    The   Company's  subsidiaries  must  comply  with  certain  minimum  capital
requirements under applicable state laws and regulations. The long-term  portion
of  principal and interest payments under the  notes issued by Health Net to the
Selling Stockholder in connection with the Conversion is subordinated to  Health
Net  meeting minimum capital  requirements under applicable  California laws and
regulations. As  of  December  31,  1995, the  Company's  subsidiaries  were  in
compliance with minimum capital requirements.
 
IMPACT OF INFLATION AND OTHER ELEMENTS
 
    The managed health care industry is labor intensive and its profit margin is
low.  Hence, it is  especially sensitive to inflation.  Increases in health care
costs without corresponding increases in premiums could have a material  adverse
effect on the Company.
 
    Various  federal and state legislative initiatives regarding the health care
industry have been proposed during recent legislative sessions, and health  care
reform  and  similar  issues continue  to  be  in the  forefront  of  social and
political discussion. If health care  reform or similar legislation is  enacted,
such  legislation  could  impact the  Company.  Management cannot  at  this time
predict whether any such initiative will be enacted and, if enacted, the  impact
on the financial condition or operations of the Company.

<PAGE>
                                    BUSINESS
 
   
    The  Company is  one of  the largest  managed health  care companies  in the
United States, with more than 1.9 million full-risk and ASO members. The Company
provides a comprehensive range of health  care services through HMOs located  in
the following four regions: California, the Northeast (Connecticut, Pennsylvania
and  New Jersey), the Northwest (Washington, Oregon and Idaho) and the Southwest
(Colorado  and  New  Mexico).  Health  Net,  the  Company's  HMO  subsidiary  in
California,  with  approximately 1.34  million  members, is  the  second largest
provider of managed health  care services in the  state. The Company operates  a
PPO  network, which provides access to health  care services to over 4.6 million
persons in 38  states, and  also owns two  health and  life insurance  companies
licensed to sell insurance in 33 states and the District of Columbia.
    
 
    The  Company's HMOs market their traditional HMO products to employer groups
and their  Medicare  and Medicaid  products  directly to  eligible  individuals.
Health  care services that are provided to the Company's members include primary
and specialty physician care, hospital care, laboratory and radiology  services,
pharmacy  services,  dental  and  vision care,  skilled  nursing  care, physical
therapy and  mental health  care.  The Company's  HMO service  networks  include
approximately  17,500  primary  care  physicians,  40,500  specialists  and  614
hospitals. The  Company utilizes  sophisticated  medical management  systems  to
reduce  excess  utilization  of  health  care  services.  The  Company  is  also
developing a new medical management system which will utilize clinical protocols
and triage procedures to  direct members to the  most appropriate provider.  The
Company believes that this new system, which it calls "Fourth Generation Medical
Management,"   will  represent   a  major  advance   in  applying  sophisticated
information systems to the practice of medicine.
 
GROWTH STRATEGY
 
   
    The Company's  growth  strategy  is focused  on  increasing  enrollment  and
profitability  through  (i) continued  commercial  and Medicare  risk enrollment
expansion  in  existing  markets,  (ii)  membership  and  revenue  growth   from
acquisitions  in  both  new and  existing  markets and  (iii)  improving medical
management of health plans  in new markets and  continued refinement of  medical
management in existing markets. The Company actively seeks to increase growth in
its  existing markets  by increasing  penetration of  its existing  product line
through continued  investment in  its sales  and marketing  capabilities and  by
introducing  new  products that  both increase  plan  flexibility and  reach new
potential customers,  including Medicare  and Medicaid  recipients. The  Company
intends  to expand on its recent success  with its Medicare risk products, which
products have experienced  rapid enrollment  and premium  growth throughout  the
last  three  years. The  Company also  plans  to capitalize  on the  breadth and
quality of its  provider network and  its high quality,  affordable products  to
drive  enrollment growth in  existing markets. The Company  also plans to expand
into contiguous  markets  that  will  allow  it  to  increase  enrollment  while
leveraging its existing infrastructure.
    
 
    The  Company plans to continue its expansion into geographic areas which the
Company believes represent attractive service markets. The Company believes such
markets have characteristics, including relatively low levels of managed  health
care  and existing  health care  delivery systems,  which can  benefit from more
efficient medical management. The Company  has targeted the Northeastern  United
States  as an  attractive service market  and, in  this regard, in  1995 began a
strategy  of  acquiring  significant  HMO  plans  in  the  Northeast  with   the
acquisition of M.D. Health Plan, operating in Connecticut, and Greater Atlantic,
operating  in Pennsylvania and  New Jersey. These  acquisitions, which accounted
for 237,125 members at year end 1995, provide the Company with a platform in the
Northeast  from   which  to   pursue  further   acquisition  and   consolidation
opportunities.
 
    The  Company believes it has established a reputation as a leader in medical
management through optimizing the utilization of health care services among  the
members  of its health plans. The  Company seeks acquisitions where there exists
relatively high  utilization  of  health  care services  when  compared  to  the
Company's  existing health plans. In seeking such plans, the Company believes it
can  have  a   direct  impact   on  health  care   utilization  (and   resulting
profitability)  through the application of its medical management techniques. As
evidence of this impact, at the time the Company acquired M.D. Health Plan, this
plan's acute hospital  days per  thousand commercial  members was  approximately
300. In December 1995, after the
 
                                       17
<PAGE>
Company's  medical  management  system  had been  installed,  hospital  days per
thousand had  decreased to  below 200,  a level  consistent with  the  Company's
Southwest  and Northwest  plans. The Company  is attempting  to further decrease
utilization through the implementation of its new medical management procedures.
 
THE MANAGED HEALTH CARE INDUSTRY
 
    In response to the rapid increases in health care costs, employers, insurers
and government entities have sought cost-effective alternatives to  conventional
indemnity  insurance for  the delivery  of and  payment for  quality health care
services. The  integration of  the delivery  of, and  payment for,  health  care
services  distinguishes HMOs from conventional health insurance plans. The goals
of HMOs are to provide their members  with access to quality health care,  while
employing  a business strategy and management systems designed to encourage more
cost-effective use  of  health  care delivery  systems.  Such  cost  containment
strategies include providing access to primary physician care and other services
on  a fixed, prepaid basis, monitoring  hospital admissions and lengths of stay,
using a  system  of  specialist  referrals,  using  non-hospital  based  medical
services,  and emphasizing preventive care.  To accomplish these objectives, the
following basic HMO models have evolved:
 
    - Network Model HMOs contract with several physician groups and  independent
      or individual practice associations ("IPAs").
 
    - Individual  or Independent  Practice Association  HMOs ("IPA  Model HMOs")
      contract through one or  more IPAs, which are  physician entities that  in
      turn  subcontract  with  individual  physicians  to  provide  HMO  patient
      services.  Those  physicians  continue  to  provide  services  to  non-HMO
      patients  in  their  separate  private  practices,  while  also  providing
      services to HMO patients (and often PPO patients as well) through an IPA.
 
    - Staff Model HMOs directly  employ physicians and  usually own the  offices
      and clinics utilized by the physician staff.
 
    - Group  Model HMOs contract, often on  an exclusive basis, with a physician
      group practice. In many cases, the HMO also owns the offices and clinics.
 
    Health Net is a Network Model HMO and the Company's other HMOs operate under
the IPA Model with the  exception of Greater Atlantic  which operates on both  a
Staff and an IPA Model HMO basis.
 
MARKETS
 
    As  of  December 31,  1995,  the Company  owned  and operated  HMOs  in four

    CALIFORNIA.    The  California  market is  characterized  by  a concentrated
population and a relatively high proportion of large employer groups (over 1,000
employees). Health Net is the second-largest  HMO in the State of California  in
terms of membership. As of December 31, 1995, Health Net was licensed to operate
its commercial HMO business in 47 of the 58 counties in the State of California,
which  counties  represent  over  81%  of  the  population  in  California.  HMO
enrollment represented  35%  of  the  population  of  California  in  1995.  The
Company's  commercial  HMO membership  in California  at  December 31,  1995 was
1,258,714 which  represented an  increase  of 6.6%  during 1995.  The  Company's
Medicare  risk membership in  California at December 31,  1995 was 107,875 which
represented an increase of 55.9% during 1995. The Company does not believe  that
its California commercial membership will grow significantly in 1996.
 
    NORTHEAST.      The   Northeast  region   currently   includes  Connecticut,
Pennsylvania and New Jersey. The Company commenced operations in this region  in
1994  with  the acquisition  of  a PPO  network  and significantly  expanded its
operations with the acquisition  of M.D. Health Plan  in March 1995 and  Greater
Atlantic  in December 1995. HMO enrollment  represented 21% of the population of
both Connecticut and Pennsylvania in 1995. The Company believes M.D. Health Plan
is the third largest  HMO in terms  of membership in  the State of  Connecticut.
M.D.  Health  Plan's commercial  HMO membership  in  Connecticut was  124,771 at
December 31, 1995 which represented an increase of 160% during 1995. The Company
believes Greater Atlantic is the third largest HMO in terms of membership in the
state  of  Pennsylvania.  Greater   Atlantic's  commercial  HMO  membership   in
Pennsylvania  was 79,278 at  December 31, 1995 which  represented an increase of
6.2% during 1995.  Greater Atlantic's Medicare  risk membership in  Pennsylvania
was  13,206 at December 31,  1995 which represented an  increase of 24.5% during
1995.
 
    NORTHWEST.  The Northwest region's population is principally concentrated in
Portland, Oregon and Seattle and  Spokane, Washington. The Company's  Washington
HMO  also services  a limited  number of  residents who  reside in  the State of
Idaho. In the last several years, Portland, Seattle and Spokane have experienced
population growth  rates greater  than the  national average  and an  increasing
percentage  of the population in  each of these areas  has enrolled in HMOs. HMO
enrollment represented 35% and 25% of  the population of Oregon and  Washington,
respectively,  in 1995. In  Washington and Oregon, the  Company believes that it
ranks second and seventh,  respectively, with respect  to total membership;  the
Company  believes that it  ranks first in  Washington and second  in Oregon with
respect to the size of its  primary care physician and specialist networks.  The
Company's  commercial HMO membership  in Oregon was 43,977  at December 31, 1995
which represented an increase of 33.1% during 1995. The Company's commercial HMO
membership in Washington was 124,665 at  December 31, 1995 which represented  an
increase  of  11.4%  during  1995. The  Company's  Medicare  risk  membership in
Washington was  1,455 at  December 31,  1995 which  represented an  increase  of
169.4% during 1995.
 
    SOUTHWEST.   The  Southwest region includes  the States of  Colorado and New
Mexico.  The  Company's  employer  groups   in  the  Southwest  region   consist
predominantly  of  companies  with  fewer  than  50  employees.  HMO  enrollment
represented  35%  and  19%  of  the  population  of  Colorado  and  New  Mexico,
respectively,  in 1995. The Company believes that it is the fifth-largest HMO in
Colorado as  measured by  total membership  and  the size  of its  primary  care
physician  and  specialist  provider  networks.  The  Company's  commercial  HMO
membership in Colorado  was 39,665  at December  31, 1995  which represented  an
increase  of 22% during 1995. The  Company's Medicare membership in Colorado was
8,923 at December 31, 1995 which  represented an increase of 20.3% during  1995.
In   New  Mexico,  the  Company  believes  that  its  ranks  fourth  and  third,
respectively, as  measured by  total membership  and the  size of  its  provider
network.  The Company's  commercial HMO membership  in New Mexico  was 26,251 at
December 31,  1995  which represented  a  decrease  of 11.7%  during  1995.  The
Company's  Medicare risk membership in New Mexico was 1,767 at December 31, 1995
which represented an increase of 15.9% during 1995.
 
SERVICES AND PRODUCTS
 
    The Company offers a broad range of managed health care and related products
and services which are described below.  The products and services offered  vary
by region and location.
 
    COMMERCIAL  MANAGED HEALTH CARE PRODUCTS.  The Company's HMOs, through their
health care  providers,  offer members  a  comprehensive range  of  health  care
services, including ambulatory and outpatient
 
                                       19
<PAGE>
physician  care, hospital care,  pharmacy services, eye  care, mental health and
ancillary diagnostic  and  therapeutic  services.  The  Company  offers  a  full
spectrum  of managed  health care  products including  conventional HMO, managed
indemnity, point-of-service and customized HMO products. The Company's  strategy
is  to  offer a  wide  range of  managed health  care  products and  services to
employers to assist employers  in containing health care  costs. The pricing  of
the  products offered  is designed to  provide incentives to  both employers and
employees to select and enroll in the products with greater managed health  care
and  cost containment  elements. While a  majority of the  Company's members are
covered by conventional HMO  products, the Company is  continuing to expand  its
other product lines, thereby enabling it to offer flexibility to an employer and
to tailor its product to an employer's particular needs.
 
    The  integrated health care  programs offered by  the Company's HMOs include
traditional Network and  IPA Model  HMO products,  which are  intended to  offer
quality  care,  cost containment  and comprehensive  coverage; a  matrix package
which allows employees to select  their desired coverage from alternatives  that
have    interchangeable    outpatient   and    inpatient    co-payment   levels;
point-of-service programs which  offer a  multi-tier design  that provides  both
conventional  HMO and  indemnity-like (in-network  and out-of-network)  tiers; a
PPO-like tier which  allows members to  self-refer to the  network physician  of
their  choice; and a managed indemnity plan, which is provided for employees who
reside outside of its HMO service areas.
 
    MEDICARE RISK.    The  Company  significantly  expanded  its  Medicare  risk
business  in 1995. During 1995 the  Company added 54,536 Medicare risk enrollees
and, as of December 31, 1995, the  Company's Medicare risk plans had a  combined
membership  of  approximately 133,000.  The  Company expects  its  Medicare risk
business to continue to significantly increase in the future.
 
    The Company offers its Medicare risk products directly to individuals and to
employer groups. To enroll in a Company Medicare risk plan covered persons  must
be  eligible for Medicare. Health care services normally covered by Medicare are
provided or arranged for by  the Company, in conjunction  with a broad range  of
preventive   health   care   services.  The   federal   Health   Care  Financing
Administration ("HCFA") pays to the Company  for each enrolled member a  monthly
fee  based, in part, upon the "Adjusted  Average Per Capita Cost," as determined
by HCFA's analysis of fee-for-service costs related to beneficiary demographics.
Depending on plan design and  other factors, the Company  may charge a member  a
premium or prepaid charge in addition to the monthly fee paid by HCFA.
 
    The  Company's Health  Net subsidiary intends  to introduce  a Medicare risk
point-of-service product  in  the  first  half of  1996.  The  two-tier  product
combines  features of a standard Medicare risk HMO with an option for the member
to seek health care services outside of the HMO network, which outside  services
carry higher co-payments and co-insurance compared with services provided inside
the  HMO network. The Company believes that this product will provide additional
marketing opportunities to  retirees of  large employers,  Health Net's  largest
market  segment. Introduction of  the product is  contingent upon HCFA approval.
The Company believes this approval will be forthcoming in the spring of 1996.
 
    The Company's California Medicare risk product was licensed and certified to
operate in 31 California counties (20 full counties and 11 partial counties)  as
of  December 31, 1995.  The Company's other  HMOs are licensed  and certified to
offer Medicare  risk plans  in 13  counties in  Colorado, five  counties in  New
Mexico,  six  counties  in Washington,  four  counties in  Pennsylvania  and two
counties in New Jersey.  The Company is currently  applying for a Medicare  risk
contract  in Oregon and  Connecticut. The Company has  contracted with more than
5,800 primary care physicians,  more than 13,500  specialty physicians and  more
than  180  hospitals  to  provide  services  to  its  Medicare  risk  members in
California, and the  Company's HMOs  in the Southwest,  Northwest and  Northeast
regions  have contracted with approximately 2,100 primary care physicians, 6,500
specialty physicians and 105 hospitals to provide services to its Medicare  risk
members.
 
    MEDICAID  PRODUCTS.  With  the acquisitions of M.D.  Health Plan and Greater
Atlantic, the  Company  significantly expanded  its  Medicaid business  and,  at
December 31, 1995, the Company had an aggregate of approximately 50,000 Medicaid
members. In addition, the Company's HMOs in Washington and Oregon began offering
Medicaid  products in 1995. To enroll  in these Medicaid products, an individual
must be eligible for  Medicaid benefits under  the appropriate state  regulatory
requirements.  These  HMOs offer,  in  addition to  standard  Medicaid coverage,
certain  additional  services   including  dental  and   vision  benefits.   The
 
                                       20
<PAGE>
applicable  state agency pays the Company's HMOs a monthly fee for each Medicaid
member enrolled on  a percentage of  fee-for-service costs. As  of December  31,
1995,   Greater   Atlantic  had   approximately   28,000  Medicaid   members  in
Pennsylvania, M.D.  Health  Plan had  approximately  8,000 Medicaid  members  in
Connecticut,  and the Company's HMOs in  Washington and Oregon had approximately
11,000 and 2,000 Medicaid members in their service areas, respectively.
 
    ADMINISTRATIVE SERVICES  ONLY  BUSINESS.   The  Company  also  provides  TPA
services  to large  employer groups  throughout its  service areas.  Under these
arrangements, the Company provides claims processing, customer service,  medical
management  and  other administrative  services  without assuming  the  risk for
medical costs. The  Company is  generally compensated  for these  services on  a
fixed  per member per month  basis. These services are  currently offered in the
Northeast and  Southwest  regions,  with  101,257  members  and  2,753  members,
respectively, as of December 31, 1995.
 
    INSURANCE  PRODUCTS.    The Company  offers  indemnity products  as  part of
multiple option products  in California,  Colorado, New  Mexico and  Washington.
These   products  are  offered  by  the  Company's  health  and  life  insurance
subsidiaries which are licensed to sell insurance in 33 states and the  District
of  Columbia. Through  these subsidiaries, the  Company also  offers HMO members
certain auxiliary non-health products such  as group life, accidental death  and
disability  and short-term disability insurance, in conjunction with its managed
care products.
 
    PPO NETWORK  SERVICES.   The  Company's  PPO network  subsidiary,  Preferred
Health  Network, Inc.  ("PHN"), provides  PPO and  workers' compensation network
services to over 4.6 million covered persons in 38 states. These figures include
PHN's acquisition in January 1996  of a PPO network  operating in the states  of
Illinois,  Indiana, Nebraska  and Wisconsin with  approximately 825,000 members.
The Company  intends  to continue  to  expand such  operations  into  additional
states, as appropriate.
 
    WORKERS'  COMPENSATION PRODUCT.  Health  Net Comp-24, the Company's non-risk
workers' compensation product in California  ("Comp-24"), is an integrated  full
service  managed care workers' compensation  program designed to deliver managed
medical care  to reduce  workers' compensation  medical expenses  for  insurance
carriers  and  self-insured  employers.  Comp-24  combines  medical  cost-saving
techniques and  workers' compensation  disability management  with the  goal  of
halting inflationary trends and reducing overall costs in workers' compensation.
The  initial strategy  of Comp-24,  which began operations  in July  1994, is to
create multiple  alliances with  large, well-established  regional and  national
insurance  carriers and to provide administrative services to large self-insured
employers. Consumers of the  Comp-24 product will have  access to a  specialized
provider  network and tailored  medical management, quality  controls, and other
specialized   administrative   capabilities.    Currently,   Comp-24    provides
administrative  workers' compensation  services to  American International Group
Claim Services, Republic Indemnity and ITT Hartford. The Company also intends to
expand its Comp-24 product  line by offering a  "24 hour" workers'  compensation
coverage.  PHN also offers a non-risk  workers' compensation product, similar to
Comp-24, in certain of its service areas.
 
    SPECIALTY PRODUCTS.    The  Company's comprehensive  product  offering  also
includes supplemental programs for managed chiropractic care, vision coverage, a
managed mental health/substance abuse program and a prescription drug program.
 
    WELLNESS  PROGRAMS.    The  Company  emphasizes  the  importance  of  health
education, disease prevention and adoption  of healthier lifestyles through  its
"Wellness  Programs." Management believes that health  awareness can be a factor
in the reduction of health care costs. Wellness Programs are offered directly to
employees at  the  employees'  work  site  or  through  primary  medical  groups
("PMGs").  PMGs are required and encouraged (in the form of increased capitation
payments) to offer educational programs and preventive health care  information.
To date, Wellness Programs have focused on topics such as prenatal care, smoking
cessation,  weight management, back care, diabetes  and exercise. In addition to
the health care benefits,  the Company believes that  its Wellness Programs  are
unique  and provide it  with a marketing advantage  which differentiates it from
its competitors.

PROVIDER SERVICES AND ARRANGEMENTS
 
    PHYSICIAN RELATIONSHIPS.  Upon enrollment in one of the Company's HMO  plans
(except  for M.D. Health Plan), each member  selects a primary care physician or
PMG from the HMO's provider panel.  The primary care physicians and PMGs  assume
overall  responsibility for  the care  of members  and determine  the nature and
extent of services provided to any given member. Medical care provided  directly
by  such physicians includes the treatment  of illnesses not requiring referral,
as well as  physical examinations,  routine immunizations,  maternity and  child
care  and other preventive health services. In conjunction with medical director
review, the  primary  care  physicians  and  PMGs  are  responsible  for  making
referrals to specialists and hospitals. In Connecticut, the M.D. Health Plan HMO
is offered on an "open panel" basis under which members may access any physician
in the network without first consulting a primary care physician.
 
    The  following table sets  forth the approximate number  of primary care and
specialist physicians with whom  the Company's HMOs (and  certain of such  HMOs'
PMGs)  contracted as of December 31, 1995 by its plans in each of the geographic
regions in which it had active HMO operations:

</TABLE>
 
    Physician contracts  are  generally  for  a  period  of  one  year  and  are
automatically   renewable  unless  terminated,  with  certain  requirements  for
maintenance of  good professional  standing and  compliance with  the  Company's
quality, utilization and administrative procedures. Market pressures have caused
the  Company to  undertake a  review of  the financial  terms of  contracts with
certain of its physician providers.  In California, the primary care  physicians
and  PMGs generally receive a monthly  "capitation" fee for every member served.
The capitation fee  represents payment  in full  for all  medical and  ancillary
services specified in the service agreements. The non-physician component of all
hospital  services is  covered by  a combination  of capitation  and/or per diem
charges. In such capitated arrangements,  in cases where the capitated  provider
cannot  provide  the  health  care  services  needed,  such  providers generally
contract with specialists and other  ancillary service providers to furnish  the
requisite services pursuant to capitation agreements or negotiated fee schedules
with  specialists.  The Company's  HMOs  outside California  generally reimburse
physicians according to a discounted fee-for-service schedule.
 
    HOSPITAL RELATIONSHIPS.  The Company's HMOs provide hospital care  primarily
under  contracts with selected  hospitals in their  service areas. Such hospital
contracts  generally  provide   for  multi-year  terms,   with  limited   annual
reimbursement  increases,  and  provide  for payments  on  a  variety  of bases,
including capitation, per diem rates, case rates and discounted  fee-for-service
schedules.
 
    Covered  hospital inpatient care for a  member is comprehensive; it includes
the services of physicians, nurses and other hospital personnel, room and board,
intensive care, laboratory and x-ray services, diagnostic imaging and  generally
all  other services normally provided by  acute-care hospitals. In the Company's
IPA Model HMOs,  once a member  is admitted  to a hospital,  nurses employed  or
designated   by  the  HMO  monitor  the   progress  of  the  member's  continued
hospitalization by reviewing medical charts in the hospital, consulting with the
attending physician and reporting  back to the  physician medical director.  The
nurse updates the member's status on a daily basis into the Company's management
information  system. In  the Company's IPA  Model HMOs,  a daily hospitalization
report is generated, and the status of each hospitalized member is reviewed by a
medical director on  a daily  basis. The HMO  nurses and  medical directors  are
actively  involved  in  discharge  planning  and  case  management,  which often
involves the  coordination of  community  support services,  including  visiting
nurses,  physical  therapy,  durable  medical  equipment  and  home  intravenous
therapy.
 
    OTHER MEDICAL SERVICES.  Certain medical and surgical procedures,  including
laboratory  tests,  diagnostic radiology  services  and ambulatory  surgery, are
performed on  an  outpatient basis.  Other  outpatient services  include  crisis
intervention,  group therapy and  counseling services, substance-abuse services,
physical therapy
 
                                       22
<PAGE>
and other similar services for which hospitalization is not medically necessary.
These services, as well as optional riders for pharmaceuticals and eye care, are
provided to  members  through  contracting  physicians  and  other  health  care
providers,  who  are generally  paid according  to a  discounted fee-for-service
schedule.
 
MANAGEMENT INFORMATION SYSTEMS
 
    The Company  operates a  sophisticated  management information  system  that
gathers  and stores data on its members and physician and hospital providers. It
contains  all  of  the  Company's  necessary  membership  and  claims-processing
capabilities as well as marketing and medical utilization programs. An effective
management  information system is  critical to the  Company's operation. In 1995
the Company  commenced  the installation  of  the AMISYS  operating  and  MACESS
document  imaging systems at its HMOs  outside of California. Within California,
the Company will continue  to utilize its  internally developed ABS  information
system  to  support  its Health  Net  plan  in the  highly  capitated California
environment. These systems will provide the Company with an integrated and  more
efficient  system of billing,  reporting, member services  and claims processing
and the ability to examine member encounter information for the optimization  of
clinical outcomes.
 
    In 1995, the Company embarked on a multi-year project to develop and install
a  new  information system  designed to  facilitate  the seamless  management of
patients throughout the  entire health care  continuum. This "Fourth  Generation
Medical  Management"  project  will  encompass  regional  data  banks containing
clinical data about each  of the Company's health  plan members. This data  will
serve  as the basis for enhanced clinical decision making. Physicians, hospitals
and the  Company's case  managers will  have  access to  expert systems  and  an
ever-expanding  library of clinical protocols which  will help in optimizing the
diagnosis and treatment decisions for each health plan member. In addition,  the
Company  will  create regional,  comprehensive member  support centers  which it
believes will strengthen the connection  between members and the Company.  These
centers will serve as the primary contact for members, offering expert triage by
nurses  and  directing  members  to  the  most  appropriate  provider.  Outbound
activities of the call centers will  include clinical reminder calls to  members
and  consultive support for  self-care protocols. The  Fourth Generation Medical
Management system will  undergo testing  in 1996. The  Company anticipates  that
this  system will be  fully operational in at  least one plan  before the end of
1996 and installed in all the Company's plans within three years.
 
COST CONTAINMENT
 
    The primary care physician or PMG is responsible for authorizing all  needed
medical care except for emergency medical services. By coordinating care through
such physicians in cases where reimbursement includes risk-sharing arrangements,
the  Company believes that inappropriate use of medical resources is reduced and
efficiencies are achieved.
 
    To limit possible abuse in utilization of hospital services, a certification
process precedes the admission of each non-emergency patient member, followed by
continuing review during the patient's  hospital stay. In addition to  reviewing
the  appropriateness  of hospital  admission  and continued  hospital  care, the
Company plays an active role in  evaluating alternative means of providing  care
to   enrollment  members  and  encourages  the  use  of  outpatient  care,  when
appropriate, to  reduce the  cost that  would otherwise  be associated  with  an
inpatient hospital admission.
 
QUALITY ASSURANCE
 
    Quality  assurance is  a continuing  priority for  the Company.  Each of the
Company's HMOs  has  a  quality  assurance  plan  administered  by  a  committee
comprised  of medical directors and primary  care and specialist physicians. The
committees'  responsibilities  include  periodic  review  of  medical   records,
development  and implementation  of standards of  care based  on current medical
literature and  community  standards and  the  collection of  data  relating  to
results of treatment. All of the Company's HMOs also have a subscriber grievance
procedure  and/or a member satisfaction program  designed to respond promptly to
member grievances. Aspects of such member service programs take place both  with
the  participating physicians and the Company's  HMOs. They are coordinated with
other aspects  of  the Company's  operations,  including quality  assurance  and
utilization management, medical policy and marketing. The following projects and
reviews help to assess the Company's progress in this area.
 
                                       23

    NCQA  ACCREDITATION.  The National  Committee for Quality Assurance ("NCQA")
is an independent, non-profit organization that reviews and accredits HMOs. NCQA
assesses an  HMOs  quality improvement,  utilization  management,  credentialing
process, commitment to members' rights and preventive health services. HMOs that
comply  with  NCQA's  review  requirements and  quality  standards  receive NCQA
accreditation. After an NCQA  review is completed, NCQA  will issue one of  four
designations.  These  are  (i) full  accreditation  for three  years;  (ii) full
accreditation for  one  year;  (iii) provisional  accreditation  for  twelve  to
eighteen months to correct certain problems with a follow-up review to determine
qualification  for accreditation; and  (iv) not accredited.  Health Net received
full one year accreditation from the NCQA in 1995. The Company's Washington  HMO
had  its initial  NCQA accreditation  site visit  in July  of 1995  and received
provisional accreditation.  Greater Atlantic  also has  received full  one  year
accreditation.  The  Company's  remaining  HMOs have  already  submitted  or are
currently  preparing  applications  for   NCQA  accreditation,  and  such   HMOs
anticipate that NCQA accreditation site visits will take place in 1996 and early
1997.
 
    HEDIS.   In 1994, the Company's  California HMO participated in a nationwide
pilot project  known  as the  Health  Plan  Employer Data  and  Information  Set
("HEDIS"),  the purpose of which  was to test the ability  of 21 health plans to
collect and report on 36 indicators of quality and performance. The project  was
developed  under the auspices of the NCQA.  The results of the project (which is
commonly referred to as  a "quality-report card") were  released in early  1995.
According  to the results of the HEDIS project, the Company's California HMO was
successful in reducing discretionary hospital  bed days while maintaining  rates
of  utilization of major medical procedures that were comparable to those of the
other participating plans. In June 1995, the Company's HMOs in the Northwest and
Northeast regions likewise submitted  HEDIS data to NCQA,  the results of  which
indicated that these HMOs quality and performance were comparable to or exceeded
major competing plans.
 
MARKETING AND SALES
 
    Marketing  is  a two-step  process  in which  the  Company first  markets to
employer groups and  then provides  information directly to  employees once  the
employer  has selected  the HMO. The  Company typically uses  its internal sales
staff to serve the large employer groups while independent brokers work with the
Company's internal sales staff to develop business with smaller employer groups.
Once selected by an employer, the  Company solicits enrollees from the  employee
base directly. In 1995, the Company marketed its programs and services primarily
through  its direct sales staff and independent brokers, agents and consultants.
During "open enrollment" periods when  employees are permitted to change  health
care   programs,  the  Company  uses  direct  mail,  worksite  and  health  fair
presentations,  telemarketing,  and   outdoor,  print,   radio  and   television
advertisements  to  attract  new  enrollees.  The  Company's  sales  efforts are
supported  by  its  marketing  division  which  includes  research  and  product
development, corporate communications, public relations and marketing services.
 
    Premiums  for each employer  group are generally contracted  for on a yearly
basis. Numerous factors  are considered  by the  Company in  fixing its  monthly
premiums,   including   employer  group   needs,  and   anticipated  health-care
utilization rates  as  forecasted  by  the Company's  management  based  on  the
demographic  composition of, and the Company's  prior experience in, its service
areas. Premiums  are  also  affected by  applicable  regulations  that  prohibit
experience  rating of  group accounts (i.e.,  setting the premium  for the group
based on  its  past  use of  health  care  services) and  by  state  regulations
governing  the manner  in which premiums  are structured and  the plan's overall
financial viability.
 
COMPETITION
 
    HMOs operate in a  highly competitive environment  in an industry  currently
subject  to  significant  changes from  business  consolidations,  new strategic
alliances, legislative reform  and market  pressures brought about  by a  better
informed and better organized customer base. The Company's HMOs face substantial
competition   from  for-profit  and  nonprofit  HMOs,  PPOs,  self-funded  plans
(including self-insured employers and union trust funds), Blue Cross/Blue Shield
plans  and  traditional  indemnity  insurance  carriers,  some  of  which   have
substantially  larger  enrollments  and  greater  financial  resources  than the
Company. The Company believes that the principal competitive features  affecting
its ability to retain and
 
                                       24
<PAGE>
increase  membership  include the  range and  prices  of benefit  plans offered,
provider network, quality of service, responsiveness to user demands,  financial
stability,  comprehensiveness of  coverage, diversity  of product  offerings and
market presence  and  reputation.  The  relative importance  of  each  of  these
features and key competitors vary by market.
 
GOVERNMENT REGULATION
 
    The  Company believes it is in compliance  in all material respects with all
current state and federal regulatory requirements applicable to the business  to
be  conducted by its  subsidiaries. Certain of  these requirements are discussed
below.
 
    CALIFORNIA HMO REGULATIONS.  California HMOs such as Health Net are  subject
to  state regulation,  principally by the  DOC under the  Knox-Keene Health Care
Service Plan Act  of 1975, as  amended (the "Knox-Keene  Act"). Among the  areas
regulated  by the Knox-Keene Act are: (i) adequacy of management, (ii) the scope
of benefits required to be made available to members, (iii) the manner in  which
premiums  are structured, (iv)  procedures for review  of quality assurance, (v)
enrollment requirements, (vi) composition of policy making bodies to assure that
plan members  have  access to  representation,  (vii) procedures  for  resolving
grievances,  (viii)  the interrelationship  between HMOs  and their  health care
providers, (ix)  adequacy  and  accessibility  of the  network  of  health  care
providers,  (x)  provider contracts  and (xi)  initial and  continuing financial
viability. Any  material  modifications to  the  organization or  operations  of
Health  Net are subject to  prior review and approval  by the DOC. This approval
process can be lengthy and there is no certainty of approval. In addition, under
the Knox-Keene Act, Health Net must  file periodic reports with, and is  subject
to periodic review by, the DOC.
 
    California  legislation which became effective  in 1993 (Assembly Bill 1672)
requires all HMOs and  health insurers that choose  to serve the small  employer
group  market in California provide health plan coverage to any small group that
applies, regardless of the health status  of the group's members. This law  also
limits  the amounts  by which  HMOs and  health insurers  may vary  the premiums
charged to different small groups based  upon their respective health care  cost
experience  or the health status of their members, and imposes a number of other
requirements regarding the terms upon which  coverage must be provided to  small
employer  groups. Compliance with  this legislation has  required the Company to
make certain changes to its small  group products. The Company does not  believe
that compliance with such legislation will have a material adverse effect on the
results of its operations.
 
    OTHER  STATE  HMO REGULATIONS.   In  each  state in  which the  Company does
business, HMOs must file periodic reports with, and their operations are subject
to periodic examination by, state  licensing authorities. In addition, each  HMO
must  meet numerous  state licensing criteria  and secure the  approval of state
licensing authorities before implementing certain operational changes, including
the development of new product offerings  and, in some states, the expansion  of
service  areas. To remain licensed, each HMO  must continue to comply with state
laws and regulations and may from time  to time be required to change  services,
procedures  or  other  aspects  of  its operations  to  comply  with  changes in
applicable laws and regulations. HMOs are required by state law to meet  certain
minimum capital and deposit and/or reserve requirements in each state and may be
restricted  from  paying dividends  to their  parent corporations  under certain
circumstances from  time to  time. Outside  of California,  such HMO  laws  also
regulate  some or  all of  the areas regulated  by the  Knox-Keene Act described
above. Several  states have  recently  increased minimum  capital  requirements,
which  increases are being phased in over a period of time. Regulations in these
and other  states  may be  changed  in the  future  to further  increase  equity
requirements.  Such increases could require the Company to contribute additional
capital to its  HMOs. Any adverse  change in governmental  regulation or in  the
regulatory  climate in any  state could materially impact  the HMOs operating in
that state. The HMO Act and state laws place various restrictions on the ability
of HMOs to  price their products  freely. The Company  must comply with  certain
provisions  of certain state insurance and  similar laws, especially as it seeks
ownership interests  in new  HMOs, PPOs  and insurance  companies, or  otherwise
expands its geographic markets or diversifies its product lines.
 
    FEDERAL  HCFA REGULATIONS.  The Company's Medicare risk products are subject
to regulation by HCFA.  Under the Company's contracts  with HCFA to offer  these
products and HCFA regulations, if premiums
 
                                       25
<PAGE>
received  for  Medicare-covered health  care  services provided  to  senior plan
members are more than  the premiums received for  the same health care  services
provided  to non-senior plan members, then  the Company must provide senior plan
members with additional benefits  beyond those required  by Medicare, or  reduce
their  premiums,  deductibles  or  copayments, if  any.  Such  products  are not
permitted to account for more than  one-half of the Company's total HMO  members
in  each of their geographic markets. HCFA has the right to audit HMOs operating
under Medicare contracts to determine the quality of care being rendered and the
degree of compliance with HCFA's contracts and regulations.
 
    THE FEDERAL HMO ACT.  Under the Federal Health Maintenance Organization  Act
of 1973 (the "HMO Act"), services to members must be provided substantially on a
fixed,  prepaid  basis without  regard to  the actual  degree of  utilization of
services. Although  premiums established  by an  HMO may  vary from  account  to
account  through composite rate  factors and special  treatment of certain broad
classes  of   members,  traditional   experience  rating   of  accounts   (i.e.,
retrospective  adjustments for a group account based on that group's past use of
health care services)  is not permitted  under the HMO  Act; prospective  rating
adjustments  are, however, allowed.  All of the Company's  HMOs (other than M.D.
Health Plan)  are  federally qualified  in  certain parts  of  their  respective
service areas under the HMO Act and are therefore subject to the requirements of
such  act  to the  extent  federally qualified  products  are offered  and sold.
However, qualification  under the  HMO Act  is not  mandatory, and  the lack  of
qualification does not prohibit the Company's HMOs from offering its products.
 
    INSURANCE REGULATIONS.  State departments of insurance (the "DOIs") regulate
insurance and TPA business conducted by certain subsidiaries of the Company (the
"Insurance  Subsidiaries")  pursuant to  various  provisions of  state insurance
codes and  regulations promulgated  thereunder. The  Insurance Subsidiaries  are
subject  to various capital reserve and other financial requirements established
by the  DOIs.  The  Insurance  Subsidiaries  must  also  file  periodic  reports
regarding  their activities  regulated by the  DOIs and are  subject to periodic
reviews of those activities by the  DOIs. The Company must also obtain  approval
from  the DOIs for  all of its  group insurance policies  and certain aspects of
their individual policies prior to issuing those policies. The Company does  not
believe that the requirements imposed by the DOIs will have a material impact on
the ability of the Insurance Subsidiaries to conduct their business profitably.
 
RISK MANAGEMENT
 
    The  Company  currently manages  risk  through various  mechanisms including
premium structure and liability coverage.
 
    PREMIUM STRUCTURE.    The Company's  premiums  are based  on  the  estimated
average medical and administrative costs per member for the expected utilization
and cost of services provided to members under the benefit plans and the benefit
riders  selected by an employer. These rates  are formulated by the Company with
the assistance of outside  actuarial consulting firms  as required. The  Company
also  calculates the  capitation rate,  where applicable,  for the  coverage and
optional riders chosen by each employer group.
 
    All employer group premium  rates generally are contracted  for on a  yearly
basis  unless the Company and the employer  agree to adjust the contract term so
that the  effective date  coincides with  the beginning  of the  group's  health
benefit  plan year or to accommodate  an established open enrollment period. The
Company may, from time to time,  guarantee limits on premiums with employers  if
contracts  are renewed. The Company's  methodology for determining premium rates
is in accordance with  federal guidelines, which  provide for community  rating,
community rating by class and adjusted community rating.
 
    LIABILITY  COVERAGE.  The Company  maintains general liability, professional
liability, workers  compensation,  property  and  casualty  and  directors'  and
officers'  liability coverage subject to  customary deductibles, limitations and
exclusions.  The  Company  also  requires  participating  physicians,  PMGs  and
participating  hospitals to maintain malpractice insurance coverage. The Company
verifies malpractice  insurance  coverage  as  part  of  its  credentialing  and
recredentialing processes.

EMPLOYEES
 
    At December 31,  1995, the  Company employed  approximately 3,500  full-time
employees  and approximately 400  part-time employees. Such  employees perform a
variety  of  functions,   including  administrative   services  for   employers,
providers,  and  members,  negotiation  of  agreements  with  physician  groups,
hospitals, pharmacies  and  other health  care  providers, handling  claims  for
payment  of hospital and other services  and providing data processing services.
The Company's employees are  not unionized and the  Company has not  experienced
any  work stoppage since  its organization. The  Company considers its relations
with its employees to be very good.
 
    On April 10, 1996,  the Company announced  a comprehensive restructuring  of
Health  Net  and the  consolidation of  certain  operational functions  of other
subsidiaries. The restructuring of Health  Net will include a reorganization  of
its  management and operating structure  and staff reductions. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

DIRECTORS
 
    The  Third Amended and Restated Certificate  of Incorporation of the Company
(the "Certificate") provides that  the Board of Directors  shall consist of  not
less  than three nor more than twenty members, the exact number to be determined
in accordance  with  the  Company's  Third Amended  and  Restated  By-Laws  (the
"By-Laws").  In accordance with the By-Laws, the  number of members of the Board

Pursuant to the Letter
 
                                       33
<PAGE>
   
Agreement, the Class A Stockholders agreed to waive their right, pursuant to the
Amended Foundation  Shareholder Agreement  dated  as of  January 28,  1992  (the
"Foundation  Shareholder Agreement") among the  Company, the Selling Stockholder
and the Class A Stockholders,  to purchase shares of  Class B Common Stock  from
the  Selling  Stockholder,  through  the  term  of  the  Foundation  Shareholder
Agreement. The Letter Agreement provides, in relevant part, that the Company and
the Class  A  Stockholders must  hold  good  faith discussions  to  determine  a
procedure,  consistent with  the terms and  conditions of  the Letter Agreement,
whereby each such Class A Stockholder may elect to sell to the Company a  number
of  shares  of Class  A Common  Stock up  to  the entire  number of  such shares
beneficially owned  by  such  Class  A Stockholder  under  the  Associate  Trust
(subject  to  applicable  restrictions  contained in  the  Credit  Facility). In
accordance with such discussions, in  February 1996, the Company repurchased  an
aggregate  of  303,879  shares  of  Class  A  Common  Stock  from  the  Class  A
Stockholders under a repurchase program adopted by the Company. In addition, the
Company has agreed to  repurchase an amount  of shares of  Class A Common  Stock
from such Class A Stockholders that is equal to the amount of shares sold by the
Company pursuant to the Offering, at a price per share equal to the net proceeds
per share to be received by the Company in the Offering.
    
 
CLASS B COMMON STOCK AND THE CALIFORNIA WELLNESS FOUNDATION
 
    The  Selling Stockholder currently holds 25,684,152 shares of Class B Common
Stock, which constitutes all of the outstanding shares of Class B Common  Stock.
The Selling Stockholder received all of such shares as a charitable recipient in
connection  with the Conversion, since the  legal requirements applicable to the
Conversion necessitated  the transfer  to a  charitable recipient  of an  amount
equal to the value of Health Net as determined by the DOC.
 
    In  connection with  the Conversion, Health  Net also issued  a $150 million
original principal  amount senior  secured  promissory note  and a  $75  million
original  principal amount subordinated  secured promissory note  to the Selling
Stockholder. In  January 1994,  the  Company made  a discretionary  $50  million
prepayment  to the  Selling Stockholder  on the  subordinated secured promissory
note, and in April 1995, the Company  paid down $135 million of the  outstanding
debt  under these  notes, leaving  a remaining  principal balance  on the senior
secured promissory note of $19.6 million due on December 31, 2006. Health  Net's
performance  under the note obligations has  been guaranteed by the Company, and
in accordance  with the  provisions of  such promissory  notes, Health  Net  has
provided the Selling Stockholder with a security interest in certain collateral.
The  long-term  portion  of  the  principal  and  interest  payments  under  the
outstanding senior secured promissory note is subordinated to Health Net meeting
certain minimum capital requirements under the Knox-Keene Act.
 
    The rights of  the Class A  Common Stock and  the Class B  Common Stock  are
identical except that the Class B Common Stock is generally non-voting. Upon the
sale  or transfer of the  Class B Common Stock by  the Selling Stockholder to an
unrelated third  party, the  Class B  Common Stock  automatically converts  into
shares  of Class A Common  Stock. The Selling Stockholder  is subject to various
volume and manner of sale  restrictions specified in the Foundation  Shareholder
Agreement  which limit  the number  of shares  that the  Selling Stockholder may
dispose of prior to December 31,  1998. In addition, the Foundation  Shareholder
Agreement,  in  conjunction  with  the Letter  Agreement,  requires  the Selling
Stockholder to offer its shares of Class B Common Stock to the Company prior  to
selling  such  shares  to any  other  person.  In this  respect,  the Foundation
Shareholder Agreement permits the  Selling Stockholder to offer  and sell up  to
80%  of the Selling Stockholder's  interest in the Class  B Common Stock (or all
but 5,136,830  of  such  shares) to  the  Company  prior to  December  31,  1998
(including  up to 3,852,623 shares in 1997 and  up to the balance of the 80% not
previously sold in 1998).  In the event the  Company declines to purchase  these
shares  offered, the Selling Stockholder will  have the right to exercise demand
registration rights prior to September  30 of each year  as to those shares  not
purchased  by the Company  during such year.  In addition, under  the terms of a
registration rights agreement dated March 2,  1995, prior to December 31,  1998,
the  Selling Stockholder has  the right to demand  two future registrations with
respect   to   up   to   8,026,298    shares   of   Class   B   Common    Stock.

Notwithstanding  its  rights upon  the expiration  or  waiver of  any applicable
restrictions, the Selling Stockholder currently intends to refrain from  selling
approximately  2.1 million shares of Class B Common Stock which may be forfeited
in the event of a final adverse ruling in the Writ Proceeding described in  Item
3  of the Company's Annual  Report on Form 10-K for  the year ended December 31,
1995.
 
   
    Prior to the completion of the Offering, the Selling Stockholder owns  53.4%
of  the combined outstanding shares  of Class A Common  Stock and Class B Common
Stock. Upon  the completion  of the  Offering  and the  application of  the  net
proceeds  from the  Offering by  the Company,  the Selling  Stockholder will own
20,547,322 shares  of  Class  B  Common  Stock  (or  19,297,642  shares  if  the
Underwriters'  over-allotment  option  is exercised  in  full) or  42.7%  of the
combined outstanding shares of Class A Common Stock and Class B Common Stock (or
40.1%  if  the  Underwriters'  over-allotment  option  is  exercised  in  full).
Notwithstanding  the Selling Stockholder's significant ownership interest in the
Company, the Selling Stockholder does not  consider itself nor does the  Company
consider  the Selling Stockholder to  be a control person  of the Company due to
the current  significant  restrictions  imposed  on  the  Selling  Stockholder's
ownership of the Class B Common Stock.
    
 
    The  Selling Stockholder  is an  independent, private  foundation created to
improve the  health  of the  people  of California.  The  Selling  Stockholder's
mission  is to  improve the  quality and  accessibility of  health promotion and
disease prevention programs and services for a culturally diverse  cross-section
of  California's  children, youth  and  families, encourage  the  integration of
health promotion and disease prevention  activities into the delivery of  health
and  human services, increase the  availability of work-related health promotion
opportunities for  California workers  and their  families, and  facilitate  the
development  of  public  policies  that  support  health  promotion  and disease
prevention. In 1995, the Selling Stockholder made 177 grants in the  approximate
aggregate amount of $55 million.
 
                          DESCRIPTION OF CAPITAL STOCK
 
   
    The  authorized capital stock of the  Company consists of 135 million shares
of Class A  Common Stock,  30 million  shares of Class  B Common  Stock, and  10
million  shares of preferred  stock, par value $0.001  per share (the "Preferred
Stock"). As of May 8, 1996, there  were 22,411,697 shares of the Class A  Common
Stock  issued and  outstanding, 25,684,152  shares of  the Class  B Common Stock
issued and  outstanding  and  no  shares  of  the  Preferred  Stock  issued  and
outstanding.
    
 
    The  Class  A  Common  Stock  is  more  fully  described  in  the  Company's
Registration Statement on Form 8-A (File  No. 1-12718), dated January 21,  1994,
and  the Company's Certificate, each of  which is incorporated by reference into
this Prospectus. The  comparison of the  Class A  Common Stock and  the Class  B
Common Stock set forth below is qualified in its entirety by reference thereto.
 
COMPARISON OF CLASS A COMMON STOCK AND CLASS B COMMON STOCK
 
    VOTING.   Holders  of the Class  A Common Stock  have one vote  per share on
matters submitted to  stockholders for approval,  while holders of  the Class  B
Common  Stock generally  have no  voting rights  other than  as required  by the
Delaware General Corporation Law.
 
    DIVIDENDS, OTHER DISTRIBUTIONS  AND MERGERS OR  CONSOLIDATIONS.  Holders  of
the  Class A  Common Stock and  Class B Common  Stock are entitled  to equal per
share cash dividends, if any, distributions upon liquidation of the Company  and
consideration  in a merger or  consolidation of the Company  (whether or not the
Company is the surviving corporation). Holders  of the Class A Common Stock  and
the  Class B Common  Stock are entitled  to equal per  share stock dividends and
stock splits, if any, except that if stock dividends in shares of Class A Common
Stock are made to  holders of Class  A Common Stock, holders  of Class B  Common
Stock may receive, on a share-for-share basis, shares of Class B Common Stock.
 
    CONVERSION  UPON SALE.  Shares of Class B Common Stock automatically convert
into shares of  Class A Common  Stock on a  one-for-one basis upon  the sale  or
other  transfer  of  Class B  Common  Stock  by the  Selling  Stockholder  to an
unrelated third party.

    Each of the U.S. Underwriting  Agreement and the International  Underwriting
Agreement provides that the obligations of the several U.S. Underwriters and the
several  Managers to pay  for and accept  delivery of the  shares are subject to
approval of certain legal  matters by counsel and  to certain other  conditions.
The  U.S. Underwriters and  the Managers are  obligated to take  and pay for all
shares of Class A Common Stock offered  hereby (other than those covered by  the
over-allotment option described below) if any such shares are taken.
 
    The  U.S. Underwriters and  the Managers initially propose  to offer part of
the shares of  the Class A  Common Stock directly  to the public  at the  public
offering  price set forth on  the cover page of this  Prospectus and part of the
shares to certain  dealers at  such price  less a  concession not  in excess  of
$      per share below the  public offering price. The U.S. Underwriters and the
Managers may allow, and such dealers may reallow, a concession not in excess  of
$      per  share to any other U.S.  Underwriter or Manager, respectively, or to
certain other dealers. After  the Offering, the public  offering price and  such
concession may be changed by the U.S. Underwriters and the Managers.

then in  effect for  shares of  Class  A Common  Stock being  sold by  the  U.S.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors and Stockholders of
Health Systems International, Inc.
Pueblo, Colorado
Woodland Hills, California
 
We  have audited the accompanying consolidated  balance sheets of Health Systems
International,  Inc.  as  of  December  31,  1995  and  1994,  and  the  related
consolidated  statements of income, stockholders' equity, and cash flows for the
years then  ended. These  financial  statements are  the responsibility  of  the
Company's  management.  Our  responsibility  is to  express  an  opinion  on the
financial statements based on our audits. The consolidated financial  statements
of  Health Systems  International, Inc.  for the  year ended  December 1993 were
audited by  other auditors  whose  report, dated  March  7, 1994,  expressed  an
unqualified opinion on those consolidated financial statements.
 
We conducted our audit in accordance with generally accepted auditing standards.
Those  standards require that we plan and perform the audit to obtain reasonable
assurance  about  whether  the  financial   statements  are  free  of   material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also  includes
assessing  the  accounting principles  used  and significant  estimates  made by
management, as well as evaluating the overall financial statement  presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In  our opinion, such  consolidated financial statements  present fairly, in all
material respects, the financial position of Health Systems International,  Inc.
at  December 31, 1995 and  1994, and the results  of its consolidated operations
and its  cash  flows for  the  years then  ended  in conformity  with  generally
accepted accounting principles.

            REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS
 
    The Board of Directors of the Company addresses its oversight responsibility
for the consolidated financial statements through its Audit Committee. The Audit
Committee  meets regularly with the independent  auditors to discuss the results
of their  audit  work and  their  evaluation of  the  adequacy of  the  internal
controls and the quality financial reporting of the Company.
 
    In  fulfilling its responsibilities in 1995, the Audit Committee recommended
to the Board of Directors, subject to stockholder ratification, the selection of
the Company's independent  auditors. The  Audit Committee  reviewed the  overall
scope and specific plans of the independent auditor's audit plans, and discussed
the  independent  auditor's  management letter  recommendations,  approved their
general audit fees and reviewed their non-audit services to the Company.
 
    The Audit Committee meetings are designed to facilitate open  communications
between  the independent  auditors and  the Audit  Committee. To  ensure auditor
independence, the independent auditors of the Company have full and free  access
of the Audit Committee.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
    ORGANIZATION AND BASIS OF PRESENTATION
 
    These  consolidated  financial  statements present  the  accounts  of Health
Systems International,  Inc.  and its  wholly-and  majority-owned  subsidiaries,
including Health Net, QualMed, Inc. ("QualMed"), HN Reinsurance Limited ("HNR"),
M.D.  Enterprises  of Connecticut,  Inc. ("MDEC")  and G.H.  Holding Corporation
("GHH") (collectively, the "Company"). All significant intercompany balances and
transactions have been eliminated in consolidation.
 
    NATURE OF OPERATIONS
 
    The Company provides a  wide range of managed  health care services  through
Health  Net, a California health  maintenance organization ("HMO"), and QualMed,
the parent  company of  a system  of  HMOs with  operations in  various  Western
states.  In March 1995,  the Company acquired  MDEC, the parent  company of M.D.
Health Plan, Inc., an HMO operating in Connecticut ("M.D. Health Plan"), and  in
December  1995 the Company acquired GHH,  the parent company of Greater Atlantic
Health Service, Inc. ("Greater Atlantic"), an HMO operating in Pennsylvania  and
New  Jersey. The  Company also  owns a  preferred provider  organization ("PPO")
network with operations in 36 states and two health and life insurance companies
with licenses to sell insurance in 33 states and the District of Columbia.
 
    In California, the  Company generally  provides services to  its members  by
contract  with  participating medical  groups on  a capitated  or fixed  fee per
member per month ("PMPM")  basis. Outside of  California, the Company  generally
provides  services to its  members through contracts  with individual physicians
and groups of physicians  on a discounted fee-for-service  basis and in  certain
areas through capitation arrangements with physician groups.
 
    HSI COMBINATION
 
    On  January 28, 1994, the Company, successor by name change to HN Management
Holdings, Inc. ("HNMH") (which was formed  in 1990 for the purpose of  acquiring
Health  Net) and QualMed completed a merger  (the "HSI Combination"). In the HSI
Combination, QualMed stockholders received  one share of  the Company's Class  A
Common  Stock for  each share  of QualMed  common stock  and, at  the same time,
previously outstanding HNMH shares (both Class  A voting and Class B  nonvoting)
were  split in a ratio  of 3.3618 shares of the  Company's Common Stock for each
previously existing share of HNMH stock.  The HSI Combination was accounted  for
as  a pooling-of-interests. In accordance  with the pooling-of-interests method,
the consolidated financial  statements of  the Company include  the accounts  of
Health  Net,  QualMed  and  their subsidiaries  for  all  periods  presented. In
addition, retroactive effect of the stock split has been given to all shares and
per share information in the accompanying consolidated financial statements.
 
    In connection with the HSI  Combination, the Company accrued certain  direct
transaction and integration costs totaling $29.7 million which were reflected as
merger-related  costs in  the Company's  1993 consolidated  statement of income.
Such fees and  expenses consist  of $17.4  million of  direct transaction  costs
(including  investment banking fees,  legal, accounting and  printing costs, and
costs associated with  the change  of control provisions  of certain  agreements
with   certain  senior  executives)  and  $12.3  million  of  integration  costs
(including employee severance,  facility consolidation,  conformity of  employee
benefits  and  other items).  Through December  31, 1995,  the Company  has made
payments for merger-related  costs of  approximately $28.9  million relating  to
these items.
 
    Management  believes that the remaining amount  of the original accrual will
be adequate for any future costs incurred. Merger costs recorded in 1994  relate
to the acquisition of MDEC discussed elsewhere herein.

    TERMINATED WELLPOINT AND BLUE CROSS OF CALIFORNIA BUSINESS COMBINATION
 
    On March 31, 1995, the Company, WellPoint Health Networks Inc. ("WellPoint")
and  Blue Cross  of California  ("BCC") entered  into an  Agreement and  Plan of
Reorganization (the "Plan of Reorganization"),  which provided for, among  other
things,   the  business  combination  of  the  Company,  WellPoint  and  certain
commercial operations of BCC (the "HSI/WellPoint Transaction").
 
    In progressing  with the  final  steps necessary  to complete  the  proposed
HSI/WellPoint  Transaction, the  Company, WellPoint and  BCC encountered certain
disagreements regarding various issues. On  December 14, 1995, the Company,  BCC
and WellPoint announced that they had been unable to resolve certain differences
and  were engaged in  discussions regarding a mutual  termination and release of
all  claims  against   one  another  related   to  the  proposed   HSI/WellPoint
Transaction. On December 28, 1995, the Company, WellPoint and BCC announced that
they  had entered into  a Settlement Agreement and  Mutual General Release dated
December 27,  1995  (the "Settlement  Agreement").  Pursuant to  the  Settlement
Agreement,  (i) all agreements among BCC and/or  WellPoint, on the one hand, and
the Company and/or  certain of  the Company's  stockholders, on  the other  hand
(including,  without  limitation, (a)  the Plan  of  Reorganization and  (b) the
Stockholder Agreements  and related  Irrevocable Proxies  dated March  31,  1995
among  WellPoint,  BCC and  each  of such  stockholders  in connection  with the
HSI/WellPoint Transaction), were terminated and (ii) all claims arising  between
BCC,  WellPoint and Mr. Leonard D. Schaeffer, the Chairman of both WellPoint and
BCC, on the one hand, and the Company and such stockholders, on the other  hand,
relating to the proposed HSI/WellPoint Transaction were released.
 
    In  connection  with  the HSI/WellPoint  Transaction,  the  Company incurred
merger-related costs totaling  approximately $20.2 million  in 1995. Such  costs
include  legal, accounting  and consulting  fees, as  well as  severance related
costs of $12.2 million resulting from agreements with certain key executives  in
contemplation of the proposed HSI/WellPoint Transaction.
 
    HEALTH NET CONVERSION
 
    On  February  6,  1992, Health  Net  received approval  from  the California
Department of Corporations ("DOC")  for the Conversion. Under  the terms of  the
Conversion  as approved by the DOC, on February 7, 1992, ownership of Health Net
was transferred to  the Company, and  Health Net contributed  $300 million to  a
qualifying   independent  charitable   organization,  The   California  Wellness
Foundation (the "Foundation").  In addition, the  Foundation received  7,640,000
(25,684,152  after giving effect to the 3.3618:1  stock split) shares of Class B
nonvoting common stock of the Company. The Foundation was established by  Health
Net  to provide  public awareness  and educational  programs to  promote healthy
lifestyles, and other health-related programs. The contribution by Health Net in
connection with the Conversion included $75 million in cash and $225 million  in
notes  payable to  the Foundation.  The Conversion  was accounted  for under the
purchase method of accounting  and the excess of  the Conversion price over  the
fair  value of net  assets acquired was  recorded as goodwill.  During 1995, the
Company eliminated approximately $33.0 million of associated goodwill (See  Note
8).
 
    STATUTORY ACCOUNTING PRACTICES
 
    All  of the Company's health plans as well as its insurance subsidiaries are
required to periodically file financial  statements with regulatory agencies  in
accordance   with  statutory  accounting  and  reporting  practices.  Under  the
California Knox-Keene Health Care Service Plan Act, Health Net must comply  with
certain  minimum  capital  or  tangible  net  equity  ("TNE")  requirements. The
Company's non-California health plans, as well as its Health and Life  Insurance
Company,  must comply with their respective state's minimum regulatory net worth
requirements generally under the regulation of the respective state's department
of insurance.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    The long-term portion of Health Net's  debt to the Foundation, as  discussed
in  Note  5, is  subordinated  to Health  Net  satisfying its  TNE requirements.
Dividends and loans by Health Net are restricted to the extent that the  payment
of  such would reduce its TNE below  the minimum requirement. As of December 31,
1995 and  1994, all  of the  Company's health  plans exceeded  their  respective
minimum TNE requirements. On a cumulative basis, the regulatory net worth of the
Company's   health  plans   exceeded  the   minimum  aggregate   requirement  by
approximately $172  million and  $145 million  at December  31, 1995  and  1994,
respectively.
 
    REVENUE RECOGNITION AND HEALTH CARE EXPENSES
 
    Each of the Company's individual HMOs generally provide health care to their
members  for  a prepaid  monthly  fee. Premiums  for  members are  recognized as
revenue in the  month in  which the members  are entitled  to service.  Premiums
collected in advance are deferred and recorded as unearned subscriber premiums.
 
    The  cost of health care services is recognized in the period in which it is
provided and  includes an  estimate of  the  cost of  services which  have  been
incurred  but  not yet  reported. Such  costs include  payments to  primary care
physicians, specialists, hospitals,  out-patient care facilities  and the  costs
associated  with  managing the  extent of  such care.  The estimate  for accrued
health care costs is based on actuarial projections of hospital and other  costs
using historical studies of claims paid. Estimates are continually monitored and
reviewed  and, as  settlements are made  or estimates  adjusted, differences are
reflected in current operations.
 
    CAPITATION AND SHARED-RISK ARRANGEMENTS
 
    The Company generally contracts in California with various medical groups to
provide professional care to certain of its members on a capitation or fixed fee
PMPM. Capitation  contracts  generally  include  provisions  for  stop-loss  and
non-capitated  services for which the  Company is liable. Professional capitated
contracts also generally contain provisions for shared risk, whereby the Company
and the medical groups share in  the variance between actual hospital costs  and
predetermined  goals. Additionally, the Company contracts with certain hospitals
to provide hospital care to enrolled members on a capitated basis.
 
    CASH AND EQUIVALENTS
 
    Cash equivalents include all  highly liquid investments  with a maturity  of
three months or less when purchased.
 
    The  Company and  its consolidated  subsidiaries are  required to  set aside
certain funds  for  restricted purposes.  As  of  December 31,  1995  and  1994,
balances  of  $2.0 million  and $3.2  million, respectively,  which are  held in
financial depository accounts, are restricted as to use.
 
    MARKETABLE SECURITIES
 
    The Company  accounts  for  investments  in accordance  with  SFAS  No.  115
"Accounting  for  Certain Investments  in Debt  and  Equity Securities"  and has
determined that all marketable securities (which are primarily comprised of debt
securities) held  as of  December 31,  1995  and 1994  are available  for  sale.
Accordingly,  such securities are carried at  fair value determined using quoted
market prices, and unrealized gains or  losses, net of applicable income  taxes,
are  recorded in stockholders' equity. The Company has also determined that such
marketable  securities  are  available  for  use  in  current  operations   and,
accordingly,  has classified such securities as current assets without regard to
the securities' contractual maturity dates.
 
    The cost of marketable securities sold is determined in accordance with  the
specific  identification method  and realized gains  and losses  are included in
investment income.
 
    The Company  and its  consolidated subsidiaries  are required  to set  aside
funds  for the protection of  their plan members in  accordance with the laws of
the various states  in which they  operate. Such restricted  funds totaled  $9.3
million  and $5.4 million at  December 31, 1995 and  1994, respectively, and are
held in

U.S. Treasury bills  and certificates  of deposit with  commercial banks.  These
investments are included in marketable securities held for sale. Interest earned
on such investments accrues to the Company and its consolidated subsidiaries and
is not restricted as to use.
 
    PROPERTY AND EQUIPMENT
 
    Property  and  equipment  are  stated at  historical  cost  less accumulated
depreciation. Depreciation is computed using  the straight-line method over  the
estimated  useful lives  of the  various classes  of assets  or the  lease term,
whichever is less. Lives of the assets range from three to 40 years.
 
    COSTS OF COMPUTER SOFTWARE DEVELOPED FOR INTERNAL USE
 
    With respect  to internal  costs  incurred in  the development  of  computer
software,  the  Company expenses  such costs  in the  period they  are incurred.
External costs incurred in the development of computer software are capitalized.
The Company capitalized approximately $12.7 million and $8.2 million of computer
software development  costs  in 1995  and  1994, respectively.  In  1993,  costs
eligible  for  capitalization  were immaterial.  Capitalized  costs  of computer
software developed for internal use are amortized using the straight line method
over the  remaining  estimated economic  life  of  four years  of  the  product.
Amortization  expense  amounted to  $2,203,000 and  $576,000  in 1995  and 1994,
respectively.
 
    GOODWILL AND OTHER INTANGIBLE ASSETS
 
    Goodwill and other intangible assets  have resulted from the Conversion,  as
well  as acquisitions which  have been accounted for  under the purchase method.
Other intangible assets  consist of the  value of employer  group contracts  and
provider  networks.  The  Company  routinely  evaluates  the  recoverability  of
goodwill and other intangible assets based on estimated future cash flows.

    CONCENTRATIONS OF CREDIT RISK
 
    Financial instruments that potentially subject the Company to concentrations
of credit risk consist primarily of  marketable securities as described in  Note
2,   cash  equivalents  and  premiums   receivable.  All  cash  equivalents  and
investments are managed  within established guidelines  which limit the  amounts
which  may  be invested  with  one issuer.  Concentrations  of credit  risk with
respect to premiums receivable are limited

1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
due to the large  number of payers comprising  the Company's customer base.  The
Company's  ten  largest  employer  groups  accounted  for  23.9%  and  43.6%  of
receivables and 24.8% and 26.7% of premium  revenue as of December 31, 1995  and
1994, respectively, and for the years then ended. In addition, the company has a
receivable  in the amount  of $20.5 million  from the State  of Connecticut that
represents claims  paid  by  the  Company  and  reimbursable  by  the  State  of
Connecticut  pursuant to a previous ASO arrangement. Included in other assets is
$18 million of this receivable.
 
    INCOME TAXES
 
    Deferred income  taxes  reflect the  net  effects of  temporary  differences
between  the carrying values  of assets and  liabilities for financial reporting
purposes and the amounts used for income tax purposes. The differences result in
taxable or deductible amounts for income  tax purposes when the reported  amount
of  the asset or liability in the  financial statements is recovered or settled,
respectively. The Company has recorded a deferred tax asset of $20.9 million  as
of  December 31, 1995. Although realization  is not assured, management believes
it is more likely than not that all of the deferred tax asset will be realized.
 
    EARNINGS PER SHARE
 
    Earnings per share  is calculated based  on the weighted  average shares  of
common  stock  and  common  stock  equivalents  outstanding  during  the periods
presented. Common  stock equivalents  arising from  dilutive stock  options  are
computed using the treasury stock method.
 
    USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS
 
    The  preparation of  the financial  statements in  conformity with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported amounts  of  assets and  liabilities and
disclosures of contingent assets  and liabilities at the  date of the  financial
statements,  and  the  reported  amounts of  revenues  and  expenses  during the
reporting period. Actual results could differ from those estimates.
 
    NEW ACCOUNTING PRONOUNCEMENTS
 
    In March  1995,  FINANCIAL ACCOUNTING  STANDARDS  BOARD STATEMENT  NO.  121,
"ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO

3.  ACQUISITIONS
    The following summarizes acquisitions and  strategic investments by HSI  for
the three years ended December 31, 1995:
 
    GHH  -- On December 1,  1995, the Company acquired  the outstanding stock of
GHH and certain of its  for-profit subsidiaries, including Greater Atlantic,  an
HMO  operating in Pennsylvania and New Jersey, for $94 million in cash and notes
(the "GHH Transaction").  In connection  with the GHH  Transaction, the  Company
also  paid  an aggregate  of $12.5  million to  certain affiliated  hospitals of
Graduate Health System, Inc. ("GHS"),  GHH's previous parent company, in  return
for  the  extension of  term and  other amendments  to such  hospitals' provider
contracts with Greater Atlantic. In  addition, pursuant to the GHH  Transaction,
the   Company  established  a  hospital   management  company  to  manage  GHS's
Philadelphia-area hospitals and acquired  certain other businesses that  provide
services  primarily to the hospitals in the GHS system. The acquisition has been
accounted using purchase accounting  and the excess of  the purchase price  over
the fair value of assets acquired in the amount of $88.4 million was recorded as
goodwill.
 
    CARE  MANAGEMENT SCIENCES CORPORATION  -- On September  8, 1995, the Company
purchased shares  of preferred  stock of  Care Management  Sciences  Corporation
("CMS")  for an aggregate  purchase price of $2  million, which shares represent
approximately 21.5% of the  outstanding capital of CMS.  The Company was  issued
warrants  to purchase additional shares  of CMS preferred stock  at the same per
share  purchase  price  of  its  initial  purchase,  which  warrants,  if  fully
exercised,  would increase the Company's ownership in CMS to 36.8%. In addition,
the Company  (as part  of the  stock acquisition)  has provided  CMS with  a  $1
million line of credit. CMS develops, licenses and supports proprietary software
related  to the health care industry. Accordingly, the Company has accounted for
its investment in CMS using the cost  method and such investment is included  in
other assets.
 
    HDS  -- On June 30, 1995, the  Company acquired shares of preferred stock of
Health  Data  Sciences  Corporation  ("HDS"),  representing  a  minority  equity
interest in HDS, for an aggregate purchase price of approximately $15.6 million.
In addition, the Company entered into certain software licensing and development
agreements  with HDS. HDS  develops, licenses and  supports proprietary software
and technology  related  to  health  care  information  management  systems.  On
November  13, 1995 and December 29, 1995, the Company acquired additional shares
of preferred stock of HDS for an aggregate purchase price of approximately  $6.3
million.  As  of  December 31,  1995,  the  Company's minority  interest  in HDS
represents  approximately  16%  of  the   total  outstanding  capital  of   HDS.
Accordingly,  the Company has accounted for its investment in HDS using the cost
method and such investment is included in other assets.
 
    MDEC -- On March 15, 1995, the Company acquired all of the outstanding stock
of MDEC, and its wholly-owned subsidiary, M.D. Health Plan, an HMO operating  in
Connecticut,  for  $95.4  million.  In  addition,  the  Company  assumed certain
contractual obligations related to MDEC stock appreciation rights equal in value
to $5.1 million. The  acquisition has been  accounted using purchase  accounting
and  the excess  of the purchase  price over  the fair value  of assets acquired
totaling $97.1 million was recorded as  goodwill in the amount of $89.1  million
and employer group contracts in the amount of $8.0 million.
 
    QMPHP -- In October 1994, the Company purchased 51% of the outstanding stock
of  QualMed Plans  for Health  of Pennsylvania,  Inc. ("QMPHP"),  a Pennsylvania
managed health  care  provider,  for  $1.1 million  in  cash.  HSI  subsequently
increased  its ownership  interest in  QMPHP to  82% through  additional capital
contributions of approximately $3.5 million.  The QMPHP acquisition resulted  in
$3   million  of  provider  network  intangible  assets.  QMPHP's  accounts  are
consolidated with those of the Company, and the minority stockholders'  interest
in  QMPHP's net assets and income (loss)  is included in the Company's financial
statements as minority interest.
 
    HUMANA -- On  July 1,  1993, QualMed  acquired certain  provider, group  and
subscriber  agreements  and certain  other assets  relating to  Humana's managed
health care business in Colorado for an aggregate

purchase price of  $1.9 million, which  purchase price was  subject to  downward
adjustment to the extent members enrolled under certain contracts subject to the
transaction  did not enroll under a Company contract. Accordingly, such purchase
price was adjusted downward by $450,000.
 
    HEALTH NET  LIFE  --  In  May  1993,  the  Company  purchased  100%  of  the
outstanding  common  stock  of  Health Net  Life  (HNL  -formerly  Sentinel Life
Insurance Company of California)  for $4.2 million. The  excess of the  purchase
price  over  the fair  value  of assets  acquired  was recorded  as  goodwill of
$470,000.
 
    Summarized below  are  the  unaudited  pro  forma  consolidated  results  of

5.  NOTES PAYABLE
 
    WELLNESS NOTE
 
    In  connection  with the  Conversion of  Health Net,  Health Net  issued two
non-negotiable promissory  notes to  the Foundation  in the  aggregate  original
principal  amount of $225 million. The  notes, a $150 million original principal
amount senior  secured promissory  note  and a  $75 million  original  principal
amount  subordinated secured promissory note, bore  interest at 10.27% and 7.96%
in the years ended 1995 and 1994,  respectively. The rate adjusts to 2.5%  above
the  three-year  treasury bill  auction  rate on  the  last business  day before
December 31, 1997, 2000, and 2003, but  will not be less than 5%. Principal  and
interest  is  due  in  quarterly  installments,  currently  based  on  a 25-year
amortization schedule;  in 1996,  the  amortization schedule  is changed  to  20
years,  and  in 1997,  the  amortization schedule  is  changed to  15  years. In
addition, commencing in 1995,  additional payments of  principal becomes due  to
the  extent  that Health  Net has  an "Excess  Cash Ratio,"  as defined,  in any
calendar year. Any remaining  unpaid principal and interest  is due on  December
31,  2006.  In  January  1994,  the Company  made  a  discretionary  $50 million
prepayment to the  Foundation on  the subordinated secured  promissory note.  In
April  1995, the  Company paid down  $135 million of  the outstanding Foundation
debt, leaving a  remaining principal  balance on the  senior secured  promissory
note of $19.6 million. (See discussion of credit facility below).
 
    Health  Net's performance under the note  obligations has been guaranteed by
the Company. In accordance with the provisions of the promissory notes described
above, Health  Net  has provided  the  Foundation  a security  interest  in  the
following  collateral:  premiums  receivable, property  and  equipment  and debt
securities held by depository (Note 2). Health Net is required to maintain funds
in a depository sufficient to

cover the debt service for the next four quarters. These funds totaled  $318,000
and $20.3 million at December 31, 1995 and 1994, respectively, and were included
in  marketable securities held for sale. In  addition, Health Net is required to
make payments to a sinking fund, commencing  in 2003, in order to provide  funds
for the unpaid principal balloon payment (plus any interest) due in 2006.
 
    The  long-term portion  of the principal  and interest  payments under these
notes is subordinated to Health Net meeting its tangible net equity requirements
under the Knox-Keene Health Care Service Plan Act.
 
    Based on the terms of the Conversion as approved by the DOC, Health Net  may
treat  as a  deemed principal  payment with respect  to the  senior secured note
payable to the Foundation any taxes, penalties or interest assessed with respect
to the Conversion (whether resulting from the recently completed examination  or
otherwise) up to a maximum of $28 million. In March 1995, Health Net and the IRS
entered  into a settlement  of all outstanding  issues raised in  the audit. The
settlements paid were treated  as a principal  payment on the  notes due to  the
Foundation. (see Note 8).
 
    CREDIT FACILITY
 
    On  April 12, 1995, the Company obtained  a five year unsecured $400 million
revolving line of credit (the "Credit Facility") from a lending syndicate led by
Bank of America. As of December 31,  1995, the Company had used $310 million  of
the Credit Facility to fund the prepayment by Health Net of $135 million in debt
to the Foundation, $100 million to fund the MDEC acquisition, and $75 million to
fund  the purchase  of GHH.  Under the  Credit Facility,  the Company  may incur
permitted subordinated indebtedness in a maximum aggregate amount not to  exceed
$150  million which  will be available  for acquisition purposes  and to provide
short-term financing to repurchase shares of stock.
 
    The Company may elect  from various short-term interest  rates based upon  a
spread  above the LIBOR rate, or the greater of the bank's reference rate or the
federal funds rate plus 1/2%. In addition, the Company may elect a  "competitive
bid  auction" in  which participating  banks are  offered an  opportunity to bid
alternative rates. The Credit Facility is for a term of five years from the date
of execution, with two one year extension options.
 
    The Company is currently  seeking to increase its  revolving line of  credit
under the Credit Facility to $700 million.
 
    OTHER NOTES PAYABLE
 
    The  Company also has various other  notes payable outstanding, both secured
and unsecured, totaling $26.8 million and $1.8 million at December 31, 1995  and
1994,  respectively.  In connection  with its  acquisition of  GHH in  1995, the
Company issued a promissory  note in the  amount of $22.5  million to GHS.  Such
note bears interest at 7.95% and is payable in 2005.
 
    The  weighted average annual  interest rate on  the Company's long-term debt
was approximately 7.4% for 1995 and 8% for each of the years 1994 and 1993.

7.  EMPLOYEE BENEFIT PLANS
 
    RETIREMENT PLANS
 
    In  1995 the Company had five separate 401(k) retirement savings plans. Such
plans are available to substantially  all employees of certain subsidiaries  age
21 or older who have completed various periods of continuous service. Non-highly
compensated  employees as defined by the Internal Revenue Code may defer up to a
maximum of 15% of their annual compensation under the 401(k) plans, while highly
compensated  employees  are  limited  to  lesser  maximums  in  compliance  with
discrimination  tests. The  Company made  certain matching  contributions to the
plans in 1995. All five of the 401(k) plans were consolidated into a single plan
effective January 1, 1996.
 
    Effective April  30, 1994,  the Company's  defined benefit  pension plan  in
effect  at  such  time was  amended  to  cease benefit  accruals.  The  plan was
subsequently terminated effective December 31,  1994. This freezing of the  plan
affects  the comparability of  net periodic pension cost  and funded status with
that of prior years. In 1994, the Company recorded a $3.1 million gain from  the
freeze.  The plan covered substantially all  Health Net employees. Benefits were
based on years of service and  the employee's compensation during the last  five
years of employment. The plan's assets consist of investments in a bank's pooled
trust  fund. Expenses under the 401(k) and defined benefit pension plans totaled
$1.3 million in 1995, $2.9 million in 1994 and $5.5 million in 1993.

</TABLE>
 
    The projected benefit  obligation was  determined using a  discount rate  of
5.25%  for 1995 and 5.25% for 1994  and an assumed rate of compensation increase
was not applicable in 1995 nor 1994. The net pension costs were determined using
the aforementioned assumptions and an expected long-term rate of return on  plan
assets of 8% for each of the years 1995, 1994 and 1993.
 
    On   December  15,  1992,  the  Company  adopted  a  Supplemental  Executive
Retirement Plan  (the "Prior  SERP"). Certain  key executives  were eligible  to
participate  in the Prior  SERP. Under the  provisions of the  Prior SERP, these
executives could  elect  to  credit  amounts  to  the  Prior  SERP  in  lieu  of
compensation. The annual amount so credited was equal to 50% of the premium that
would  be required to fund a premium variable life insurance policy. The Company
then credited the executive's SERP account with the remaining 50% premium.  Upon
death,  beneficiaries are entitled to receive the entire death benefit under the
policy  plus  an  additional  78.5%   of  policy  benefits.  At  retirement   or
termination, the executive is entitled to the cash surrender value of the policy
plus  an  additional 78.5%  of  such cash  surrender  value. The  termination or
retirement benefit must be paid to the executive in a lump sum. This Prior  SERP
was discontinued in December 1995.
 
    A  new SERP program  (the "Current SERP") was  approved effective January 1,
1996. The new SERP plan  ensures that executives who retire  at age 62 or  later
and  have worked for the  Company or a predecessor  organization for at least 15
years receive 50% of  average pay (salary and  bonus) when combined with  Social
Security  and  all other  employer provided  retirement benefits  provided under
current  and  prior  programs  including   the  accumulated  value  of   company
contributions  to  the Company's  401(k) plan  and Profit  Sharing Plan  for the
account of such individuals,  along with benefits accrued  under the prior  SERP
frozen  in 1995. Executives  with less than 15  years of service  at age 62 will
receive a reduced benefit under this  plan, and executives must accrue at  least
five  years  of service  to receive  a partial  benefit. Those  terminating with
between 5 and 10 years of service are entitled to receive a partial benefit, and
executives who terminate with 10 or more years of service will be 100% vested on
earned benefits.

    The Company also has  adopted the Health Net  Board of Directors  Retirement
Plan.  The plan covers all outside members  of the Health Net Board of Directors
retiring on or after age 65 for a  duration not to exceed the period of  service
as a director.
 
    Expense  under the Prior  SERP and Health Net  Board of Directors Retirement
Plan totaled $1.8  million in 1995,  $2.5 million  in 1994 and  $3.0 million  in
1993.
 
    POST-RETIREMENT HEALTH AND LIFE BENEFITS
 
    The  Company sponsors a defined-benefit health  care plan for its Health Net
employees that provides post-retirement medical benefits to full-time  employees
and  their  eligible dependents  for  employees who  have  worked ten  years and
attained age  55.  The  Company  pays  100% of  the  cost  of  medical,  dental,
prescription  and vision  benefits for those  employees who retire  on or before
December 1, 1995;  for employees retiring  after December 1,  1995, the  Company
pays  25% of the cost of medical coverage  for those employees with ten years of
service, increasing 5% a year to 25 years or more of service, at which time 100%
of the cost  is borne  by the  Company. The  health care  plan includes  certain
cost-sharing  features  such  as  deductibles,  coinsurance  and  maximum annual
benefit amounts for certain benefits.
 
    The following  table presents  this  plan's funded  status and  the  amounts

</TABLE>
 
    The  weighted-average annual assumed rate of increase in the per capita cost
of covered benefits (i.e., health-care cost-trend  rate) is 9% for 1996, and  is
assumed  to  decrease  gradually to  5.5%  for  2007 and  remain  at  that level
thereafter. The health-care cost-trend rate assumption has a significant  effect
on  the  amounts reported.  To illustrate,  increasing  the assumed  health care
cost-trend rates  by  one percentage  point  in  each year  would  increase  the
accumulated  post-retirement  benefit  obligation  as of  December  31,  1995 by
$200,000 and  the aggregate  of  service and  interest  cost components  of  net
periodic  post-retirement benefit cost for the  year then ended by $850,000. The
weighted-average   discount   rate   used   in   determining   the   accumulated
post-retirement  benefit obligation was 7.5% for 1995, 8.5% in 1994 and 7.5% for
1993.

    The Company also  sponsors a  life insurance  plan, funded  entirely by  the
Company.  The amount of coverage  varies with the maximum  amount of three times
earnings not to exceed  $500,000. The Company's  policy is to  fund the cost  of
benefits  for the health care and life  insurance plans in amounts determined at
the discretion of management, after consultation with an independent actuary.
 
    EMPLOYEE STOCK PURCHASE PLAN
 
    In 1993  the  Company's  Board  of Directors  approved  the  Health  Systems
International  Employee Stock  Purchase Plan,  effective February  15, 1993. The
plan provides employees  of the Company  with an opportunity  to purchase  stock
through  payroll deductions.  The Company has  reserved 1,000,000  shares of its
Class A  Common  Stock for  issuance  under  the plan.  Eligible  employees  may
purchase  up to $25,000  in fair market  value annually of  the Company's Common
Stock at 85% of the lower  of the market price on  either the first or the  last
day  of each offering period. During 1995,  1994 and 1993, 48,530 shares, 54,382
shares and 49,416 shares, respectively, were issued under the plan at prices  of
$20.93  and $23.06 in 1995,  $10.73 and $21.04 in 1994  and $10.63 and $11.90 in
1993.
 
    PERFORMANCE-BASED ANNUAL BONUS PLAN
 
    The Company has a Performance-Based  Annual Bonus Plan that qualifies  under
Section  162(m) of the Internal  Revenue Code of 1986,  as amended (the "Code").
Under the plan, if  the Company meets certain  financial and operating  targets,
certain  executives subject  to the  limitations of  Section 162(m)  of the Code
become eligible to receive annual cash bonuses  based on a maximum pool of  2.5%
of  consolidated operating income and on the executives' salaries in relation to
the pool.  Amounts payable  to such  executives from  such pool  are subject  to
downward adjustment by the Company's Compensation and Stock Option Committee.
 
    MANAGEMENT BONUS PLAN
 
    The  Company also  has a  Management Bonus  Plan whereby  certain executives
become eligible  to  receive  annual  cash  bonuses  if  the  Company  and  such
executives meet certain financial and operating targets.
 
8.  COMMITMENTS AND CONTINGENCIES
 
    IRS EXAMINATION
 
    Health  Net was under audit  by the IRS during  1995 and 1994. The principal
issue during the  course of  the audit  was whether  Health Net  qualified as  a
tax-exempt  entity for certain  periods prior to the  Conversion. In March 1995,
Health Net  and the  IRS entered  into a  settlement of  all outstanding  issues
raised  in the audit. The settlement paid was  treated as a payment on the notes
due to the Foundation, in accordance with the terms of such notes.
 
    A deferred tax liability account  was previously established by the  Company
to  cover  potential liabilities  relating to  the above  mentioned audit.  As a
result of this settlement, the deferred tax liability and associated goodwill of
approximately $33.0 million have been eliminated.
 
    FTB EXAMINATION
 
    Health Net is currently  under examination by  the California Franchise  Tax
Board  ("FTB"). Issues raised  by such examination  include, among other issues,
tax ramifications of the Conversion. Although it is not possible to predict with
any certainty the outcome of the examination, the Company's management believes,
based on advice of legal counsel, that Health Net has substantial bases for  its
positions  on issues likely to  arise during the course  of the examination. The
ultimate resolution of these matters should  not have a material adverse  effect
on the financial statements of the Company.
 
    LITIGATION
 
    In January, 1995, two purported class action lawsuits were filed against the
Company  and the members of its Board  of Directors alleging breach of fiduciary
duties to the Company's public stockholders by refusing

to seriously consider certain  acquisition bids for  the Company. The  complaint
requests  an  injunction  ordering  the directors  to  evaluate  alternatives to
maximize stockholder value, to ensure that no conflicts of directors'  interests
exist,  to account for damages allegedly  suffered, and to pay plaintiff's legal
costs. The Company and its individual  directors believe that both lawsuits  are
wholly  without  merit  and  intend  to  defend  against  each  of  the  actions
vigorously.
 
    The Company  is  involved in  various  other legal  proceedings,  which  are
routine  in its business. In the opinion of management, based upon current facts
and circumstances known by the Company,  the resolution of these matters  should
not  have a  material adverse  effect on  the financial  position or  results of
operations of the Company.
 
9.  TRANSACTIONS WITH RELATED PARTIES
    During 1993, a stockholder, prior director and the prior chief legal officer
and secretary of the Company, was a partner of a law firm from which the Company
purchased legal services in the amount of $2.4 million. The law firm became part
of the Company's in-house legal department in  July 1993, and no fees have  been
billed to the Company since then.
 
    Three  directors of  the Company  are partners  of law  firms which received
legal fees totaling $1.9  million, $1.5 million and  $4.4 million in 1995,  1994
and 1993, respectively.
 
    An  officer of a contracted hospital is also a member of the Company's Board
of Directors. Medical costs  paid to the provider  totaled $55.3 million,  $14.0
million  and $8.0 million in 1995,  1994 and 1993, respectively. Such contracted
hospital is also an employer group of the Company. The Company received  premium
revenues of $3 million annually in 1995, 1994 and 1993, respectively.
 
    A  director  of  a  subsidiary of  the  Company  is a  majority  owner  of a
contracted  provider  of   Health  Net.  The   Company  paid  professional   and
institutional capitation fees to the medical group totaling $36.7 million, $36.5
million and $55.9 million in 1995, 1994 and 1993, respectively.
 
    A  director of the Company was an officer of an employer group until October
1994. In 1994 and 1993, the Company received premium revenues of $17 million and
$14 million, respectively, from the group.
 
    A stockholder and director of the Company is an officer of a consulting firm
which received approximately $50,000 in 1995 pursuant to a consulting  agreement
to  pay for certain consulting services provided  to a subsidiary of the Company
in connection with its  warehouse operations. In addition,  a subsidiary of  the
Company,  paid approximately $90,000 and $70,000 to the consulting firm for real
estate consulting services rendered in 1995 and 1994, respectively.
 
    In 1995,  the  Company advanced  an  aggregate sum  of  approximately  $16.3
million  to three of  its former executive officers  and directors in connection
with the future repurchase of  shares of HSI Class A  Common Stock held by  such
individuals.  This  repurchase agreement  was  entered into  in  connection with
certain severance agreements  between the  Company and each  such individual  in
connection  with  his  or  her termination  of  employment.  Such  advances were
non-interest bearing and were secured  by a pledge of  shares of Class A  Common
Stock, which shares were ultimately repurchased by the Company in January 1996.
 
10. STOCK OPTION PLANS
    HSI has various outstanding stock option plans which cover certain employees
and non-employee directors. Such plans have been adopted by the stockholders and

    The accrual for the book/tax differences on net assets was established  with
the  Conversion.  The initial  amount  of the  accrual  was $34.7  million which
resulted in  a corresponding  charge  to goodwill.  In  March 1995,  Health  Net
entered  into  a settlement  with the  IRS,  resulting in  the reduction  of the
deferred tax liability and associated goodwill by $33.0 million.
 
    During the  years ended  December  31, 1995,  1994  and 1993,  tax  benefits
totaling  $8,663,000, $1,515,000 and $833,000,  respectively, were realized as a
result of compensation recognized for tax  purposes relating to the exercise  of
stock options and were recorded as an increase in additional paid-in capital.
 
    The  Company has  utilized pre-acquisition operating  losses of subsidiaries
acquired which  could  differ  from  amounts allowed  by  the  tax  authorities.
Management  believes it has adequately provided  for any increases in taxes that
might result  from  any reduction  of  the  realization of  net  operating  loss
carryforwards.

13. FAIR VALUE INFORMATION
    The Company has estimated the fair value of financial instruments held as of
December  31, 1995 and 1994 in accordance with the requirements of SFAS No. 107,
"Disclosures about Fair Value of Financial
 
                                      F-25

                       HEALTH SYSTEMS INTERNATIONAL, INC.
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
13. FAIR VALUE INFORMATION (CONTINUED)
Instruments." The estimated fair value  amounts of cash equivalents,  marketable
securities held for sale and notes payable approximate their carrying amounts in
the financial statements and have been determined by the Company using available
market  information and appropriate valuation methodologies. The carrying amount
of cash equivalents approximate  fair value due to  the short maturity of  those
instruments.  The fair  values of marketable  securities are  estimated based on
quoted market prices and dealer quotes  for similar investments. The fair  value
of  notes payable is estimated based on the quoted market prices for the same or
similar issues or on the  current rates offered to the  Company for debt of  the
same   remaining  maturities.  Considerable  judgment  is  required  to  develop
estimates  of  fair  value.  Accordingly,  the  estimates  are  not  necessarily
indicative  of the amounts the  Company could have realized  in a current market
exchange as  of  December  31,  1995  and 1994.  The  use  of  different  market
assumptions  and/or estimation methodologies  may have a  material effect on the
estimated fair value amounts.
 
    The fair value  estimates are  based on pertinent  information available  to
management as of December 31, 1995 and 1994. Although management is not aware of
any  factors that would  significantly affect the  estimated fair value amounts,
such amounts  have  not been  comprehensively  revalued for  purposes  of  these
financial  statements since that date, and  therefore, current estimates of fair
value may differ significantly.
 
14. COMMON STOCK
    The Company has two  classes of Common Stock.  The Company's Class A  Common
Stock  and Class B Common Stock have  identical rights except that upon the sale
or other transfer of the Class B Common Stock, such shares automatically convert
to Class A  Common Stock. The  Foundation is the  only holder of  record of  the
Company's Class B Common Stock.

                 [ALTERNATE PAGE FOR INTERNATIONAL PROSPECTUS]
      CERTAIN UNITED STATES TAX CONSEQUENCES TO NON-UNITED STATES HOLDERS
 
    The  following  general discussion  is a  summary  of certain  United States
federal income and estate tax consequences  of the ownership and disposition  of
Class  A Common  Stock applicable  to Non-U.S.  Holders of  such Class  A Common
Stock. A "Non-U.S. Holder"  is a person  or entity other than  (i) a citizen  or
resident of the United States, (ii) a corporation or partnership or other entity
created or organized in the United States or under the laws of the United States
or  of any state thereof, or (iii) an estate or trust whose income is includable
in gross income for United States federal income tax purposes regardless of  its
source.  For purposes  of the  withholding tax  on dividends  discussed below, a
non-resident fiduciary  of an  estate or  trust will  be considered  a  Non-U.S.
Holder.
 
    This  discussion does not consider specific facts and circumstances that may
be relevant to a particular Non-U.S. Holder's tax position and does not consider
United States  state  and local  or  non-United States  tax  consequences.  This
discussion  also does not consider  the tax consequences to  any person who is a
stockholder, partner or  beneficiary of a  holder of the  Class A Common  Stock.
Furthermore,  the following  discussion is  based on  current provisions  of the
United States  Internal Revenue  Code  of 1986,  as  amended (the  "Code"),  and
administrative  and judicial interpretation  of the Code as  of the date hereof,
all of which are subject to change. Each prospective Non-U.S. Holder is urged to
consult its own tax adviser with respect to the United States federal income and
estate tax consequences and  United States state and  local tax consequences  of
owning  and disposing  of shares  of Class A  Common Stock,  as well  as any tax
consequences arising under the laws of any other taxing jurisdiction.
 
DIVIDENDS
 
    In general, dividends paid  to a Non-U.S. Holder  will be subject to  United
States  withholding  tax  at  a 30%  rate  (or  a lower  rate  prescribed  by an
applicable tax treaty) unless the dividends are either (i) effectively connected
with a trade or  business carried on  by the Non-U.S.  Holder within the  United
States,  or  (ii) if  a  tax treaty  applies,  attributable to  a  United States
permanent establishment maintained by the Non-U.S. Holder. Dividends effectively
connected with  such  trade  or  business  or  attributable  to  such  permanent
establishment  generally will  not be  subject to  withholding (if  the Non-U.S.
Holder files certain forms with the payor of the dividend) and generally will be
subject to United States federal  income tax in the same  manner as if the  non-
U.S. Holder was a United States resident. In the case of a Non-U.S. Holder which
is  a corporation, such effectively  connected income may also  be subject to an
additional "branch  profits  tax"  (which  is generally  imposed  on  a  foreign
corporation  on the repatriation from the United States of effectively connected
earnings and profits). To determine the applicability of a tax treaty  providing
for  a lower  rate of  withholding, dividends  paid to  an address  in a foreign
country are presumed under current Treasury Department regulations to be paid to
a resident of that  country. Treasury Department  regulations proposed in  April
1996  would,  if adopted  in  final form,  require  Non-U.S. Holders  to  file a
"withholding certificate"  with  the  Company's  withholding  agent  (or,  under
certain  circumstances, a "qualified intermediary") to  obtain the benefit of an
applicable tax  treaty  providing  for  a  lower  rate  of  withholding  tax  on
dividends.  Such certificate would have  to contain the name  and address of the
holder  and  the  basis  for   any  reduced  rate  claimed.  These   withholding
certificates  would be  required for dividend  payments made  after December 31,
1999.
 
GAIN ON DISPOSITION
 
    A Non-U.S. Holder  generally will not  be subject to  United States  federal
income  tax on any gain recognized on a disposition of a share of Class A Common
Stock unless  (i) the  Company is  or has  been a  "U.S. real  property  holding
corporation"  for United  States federal income  tax purposes as  defined in the
Code (which the Company does not believe that it is or is likely to become) and,
assuming that the Class  A Common Stock is  "regularly traded on an  established
securities  market" for purposes of Section 897 of the Code, the Non-U.S. Holder
disposing of the share owned, directly or constructively, at any time during the
five-year period preceding the disposition, more than five percent of the  Class
A  Common Stock; (ii) the gain is effectively connected with a trade or business
carried on by the Non-U.S. Holder within  the United States or, if a tax  treaty
applies,  attributable to a United  States permanent establishment maintained by
the Non-U.S.  Holder,  (iii)  in  the  case of  a  Non-U.S.  Holder  who  is  an
individual,  who holds the  share as a capital  asset and who  is present in the
United States for  183 days  or more  in the  taxable year  of the  disposition,
 
                                       39
<PAGE>
either  (a) such Non-U.S. Holder has a  "tax home" (as defined for United States
federal income  tax  purposes)  in the  United  States  and the  gain  from  the
disposition  is not attributable to  an office or other  fixed place of business
maintained by such Non-U.S. Holder outside of the United States or (b) the  gain
from  the  disposition is  attributable to  an  office or  other fixed  place of
business maintained by such  Non-U.S. Holder in the  United States; or (iv)  the
Non-U.S.  Holder  is  subject  to  a tax  pursuant  to  provisions  of  the Code
applicable to certain United States expatriates.
 
FEDERAL ESTATE TAX
 
    Shares of Class A Common  Stock owned or treated  as owned by an  individual
who  is not a citizen  or resident (as defined  for United States federal estate
tax purposes) of the United  States at the time of  death will be includable  in
the  individual's gross  estate for  United States  federal estate  tax purposes
unless  an  applicable  estate  tax   treaty  provides  otherwise.  Estates   of
non-resident aliens are generally allowed a statutory credit which generally has
the  effect of offsetting  the United States  federal estate tax  imposed on the
first $60,000 of the taxed estate.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING REQUIREMENTS
 
    The Company must report annually to the Internal Revenue Service and to each
Non-U.S. Holder  the amount  of dividends  paid to,  and the  tax withheld  with
respect   to,  such  holder.  These  information  reporting  requirements  apply
regardless of whether withholding was reduced or eliminated by an applicable tax
treaty. Copies of these information returns may also be made available under the
provisions of  a specific  treaty or  agreement to  the tax  authorities in  the
country in which the Non-U.S. Holder resides.
 
    United  States backup withholding tax (which  generally is a withholding tax
imposed at the rate of 31% on  certain payments to persons that fail to  furnish
the   information  required  under  the   United  States  information  reporting
requirements) will generally not apply to dividends paid on Class A Common Stock
to a Non-U.S. Holder at an address  outside the United States, unless the  payor
has knowledge that the payee is a U.S. Holder.
 
    The  payment of the proceeds from the disposition of Class A Common Stock to
or through the United States office of  a broker will be subject to  information
reporting  and  backup withholding  at a  rate  of 31%  unless the  owner, under
penalties of perjury, certifies,  among other things, its  status as a  Non-U.S.
Holder,  or otherwise establishes an exemption. The payment of the proceeds from
the disposition of Class A Common Stock to or through a non-United States office
of a non-United  States broker  generally will, except  as noted  below, not  be
subject to backup withholding and information reporting. In the case of proceeds
from  a disposition  of Class  A Common  Stock paid  to or  through a non-United
States office of  a United  States broker  or paid  to or  through a  non-United
States  office of a non-United  States broker that is  (i) a "controlled foreign
corporation" for United States federal income tax purposes or (ii) a person  50%
or  more of whose gross income from  all sources for a certain three-year period
was effectively connected  with a United  States trade or  business, (a)  backup
withholding will not apply unless the broker has actual knowledge that the owner
is  not a Non-U.S. Holder,  and (b) information reporting  will not apply if the
broker has documentary evidence in its files that the owner is a Non-U.S. Holder
(unless the  broker has  actual knowledge  to the  contrary) and  certain  other
conditions are met, or the holder otherwise establishes an exemption.
 
    Any  amounts withheld under the backup withholding rules from a payment to a
Non-U.S. Holder  will be  refunded (or  credited against  the Non-U.S.  Holder's
United  States federal income tax liability, if any), provided that the required
information is furnished to the Internal Revenue Service.
 
    The backup withholding and information reporting rules would also be changed
by Treasury Department regulations proposed in April 1996. These regulations, if
adopted in final form, would provide that proceeds from the disposition of Class
A Common Stock after December 31,  1997 would be exempt from backup  withholding
and  information  reporting  only  if  the  Non-U.S.  Holder  complies  with the
"withholding certificate" requirements described above or otherwise  establishes
an exemption.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
    
 
    The Company's Certificate  and Bylaws  contain provisions  permitted by  the
Delaware  General Corporation Law (under which  the Company is organized) which,
in general terms, provide that directors and officers will be indemnified by the
Company for all losses that may be incurred by them in connection with any claim
or legal action in which they may become involved by reason of their service  as
a director or officer of the Company, if they meet certain specified conditions.
In  addition,  the Company's  Certificate contains  provisions permitted  by the
Delaware  General  Corporation  Law,  which  limit  the  monetary  liability  of
directors  of the Company for  certain breaches of their  fiduciary duty of care
and provide for  the advancement  by the Company  to directors  and officers  of
expenses  incurred by them  in defending suits  arising out of  their service as
such. The  Company has  also  entered into  agreements  with its  directors  and
certain  of  its  officers  which  essentially  provide  that  the  Company will
indemnify such directors and officers to the extent set forth in the Certificate
and Bylaws of the Company. In  addition, the Company maintains a directors'  and
officers' liability insurance policy.

ITEM 17.  UNDERTAKINGS.
 
    The  Company  hereby  undertakes  that,  for  purposes  of  determining  any
liability under the Securities Act, each  filing of the Company's annual  report
pursuant  to  Section  13(a)  or  Section 15(d)  of  the  Exchange  Act  that is
incorporated by reference in this Registration Statement shall be deemed to be a
new registration statement relating to  the securities offered therein, and  the
offering  of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
    Insofar as indemnification for liabilities arising under the Securities  Act
may  be permitted to directors, officers  and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company has been advised
that in the  opinion of the  Commission such indemnification  is against  public
 
                                      II-2
<PAGE>
policy  as expressed in the Securities  Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other  than
the  payment of the Company of expenses  incurred or paid by a director, officer
or controlling person of  the Company in the  successful defense of any  action,
suit  or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Company will, unless  in
the opinion of its counsel the matter has been settled by controlling precedent,
submit  to  a  court  of  appropriate  jurisdiction  the  question  whether such
indemnification by it is  against public policy as  expressed in the  Securities
Act and will be governed by the final adjudication of such issue.
 
    The Company hereby undertakes that:
 
        (1)  For purposes of determining any liability under the Securities Act,
    the information omitted from  the form of Prospectus  filed as part of  this
    Registration Statement in reliance upon Rule 430A and contained in a form of
    Prospectus  filed by the Company pursuant to Rule 424(b)(1) or (4) or 497(h)
    under the Securities  Act shall be  deemed to be  part of this  Registration
    Statement as of the time it was declared effective.
 
        (2)  For the purpose  of determining any  liability under the Securities
    Act, each post-effective amendment that contains a form of Prospectus  shall
    be  deemed to  be a  new registration  statement relating  to the securities
    offered therein, and the offering of  such securities at that time shall  be
    deemed to be the initial bona fide offering thereof.

certifies that it has  reasonable grounds to  believe that it  meets all of  the

Registration Statement to be signed on its behalf by the undersigned,  thereunto
duly authorized, in the City of Pueblo, Colorado on May 8, 1996.

Dear Sirs:

          Health Systems International, Inc., a Delaware corporation (the
"Company"), proposes to issue and sell an aggregate of 2,555,499 shares of its
Class A Common Stock, par value $0.001 per share (the "Common Stock"), to the
several Underwriters named in Schedule II hereto (the "U.S. Underwriters"), and
The California Wellness Foundation as the selling stockholder (the "Selling
Stockholder") proposes to sell to the several U.S. Underwriters an aggregate of
4,109,464 shares of the Company's Class B Common Stock, par value $0.001 per
share, which upon sale to the several U.S. Underwriters is converted into Common
Stock (the "Class B Common Stock").  The 2,555,499 shares of Common Stock to
be issued and sold to the U.S. Underwriters by the Company and the 4,109,464
shares of Class B Common Stock to be sold to the U.S. Underwriters by the
Selling Stockholder are hereinafter referred to as the "Firm Shares."  In
addition, solely for the purpose of covering over-allotments, the Selling
Stockholder proposes to sell to the U.S. Underwriters, upon the terms and
conditions set forth in Section 2 hereof, up to an additional 999,744 shares
of Class B Common Stock (the "Additional Shares").  The Firm Shares and the
Additional Shares are hereinafter collectively referred to as the "Shares."  The
Company and the Selling Stockholder are hereinafter sometimes referred to as the
"Sellers."

                                        

<PAGE>

          It is understood that the Company and the Selling Stockholder are
concurrently entering into an International Underwriting Agreement, dated the
date hereof (the "International Underwriting Agreement"), providing for the sale
of 1,666,240 shares of the Common Stock (the "Firm International Shares"), of
which 638,875 shares will be sold by the Company and 1,027,366 will be sold by
the Selling Stockholder (plus an option granted by the Selling Stockholder to
purchase up to an additional 249,936 shares of Common Stock (the "Additional
International Shares") solely for the purpose of covering over-allotments)
through arrangements with certain underwriters outside the United States and
Canada (the "Managers"), for whom Smith Barney Inc., Dillon, Read & Co. Inc.,
Dean Witter International Ltd., Robertson, Stephens & Company LLC, Salomon
Brothers International Limited and Volpe, Welty & Company are acting as lead
Managers (the "Lead Managers").  All shares of Common Stock proposed to be
offered to the Managers pursuant to the International Underwriting Agreement,
including the Firm International Shares and the Additional International Shares,
are herein called the "International Shares"; the International Shares and the
Shares, collectively, are herein called the "Underwritten Shares."

          The Company and the Selling Stockholder also understand that the
Representatives and the Lead Managers have entered into an agreement (the
"Agreement Between U.S. Underwriters and Managers") contemplating the
coordination of certain transactions between the U.S. Underwriters and the
Managers and that, pursuant thereto and subject to the conditions set forth
therein, the U.S. Underwriters may purchase from the Managers a portion of the
International Shares or sell to the Managers a portion of the Shares.  The
Company and the Selling Stockholder understand that any such purchases and sales
between the U.S. Underwriters and the Managers shall be governed by the
Agreement Between U.S. Underwriters and Managers and shall not be governed by
the terms of this Agreement or the International Underwriting Agreement.

          The Sellers wish to confirm as follows their agreement with you (the
"Representatives") and the other several U.S. Underwriters on whose behalf you
are acting, in connection with the several purchases of the Shares by the U.S.
Underwriters. 

     1.   REGISTRATION STATEMENT AND PROSPECTUS.  The Company has prepared and
filed with the Securities and Exchange Commission (the "Commission") in
accordance with the provisions of the Securities Act of 1933, as amended, and
the rules and regulations of the Commission thereunder (collectively, the
"Act"), a registration statement on Form S-3 under the Act (the "registration
statement"), including prospectuses subject to completion, relating to the
Underwritten Shares.  The term "Registration Statement" as used in this
Agreement means the registration statement (including all financial schedules
and exhibits), as amended at the time it becomes effective, and as thereafter
amended by post-effective amendment.  If an additional registration statement is
prepared and filed with the Commission in accordance with Rule 462(b) under the
Act (an "Additional Registration Statement"), the term "Registration Statement"
as used in this Agreement includes the Additional Registration Statement.  The
term "Prospectuses" as used in this Agreement means the prospectuses in the
forms included in the Registration Statement, or, if the prospectuses included
in the Registration Statement omit information in reliance on Rule 430A under
the Act and such information is included in the prospectuses filed with the
Commission pursuant to Rule 424(b) under the Act, the term "Prospectuses" as
used in this Agreement means the prospectuses in the forms included in the
Registration Statement as supplemented by the addition of the Rule 430A
information contained in the prospectuses filed with the Commission pursuant to
Rule 424(b).  The term "Prepricing Prospectuses" as used in this Agreement means
the prospectuses subject to completion in the forms included in the Registration
Statement at the time of the initial filing of the Registration Statement with
the Commission, and as such prospectuses shall have been amended from time

                                       -2-

<PAGE>

to time prior to the date of the Prospectuses.  Any reference in this Agreement
to the registration statement, the Registration Statement, any Prepricing
Prospectus or the Prospectus shall be deemed to refer to and include the
documents incorporated by reference therein pursuant to Item 12 of Form S-3
under the Act, as of the date of the registration statement, the Registration
Statement, such Prepricing Prospectus or the Prospectus, as the case may be, and
any reference to any amendment or supplement to the registration statement, the
Registration Statement, any Prepricing Prospectus or the Prospectus shall be
deemed to refer to and include any documents filed after such date under the
Securities Exchange Act of 1934, as amended, and the rules and regulations of
the Commission thereunder (collectively, the "Exchange Act") which, upon filing,
are incorporated by reference therein, as required by paragraph (b) of Item 12
of Form S-3.  As used herein, the term "Incorporated Documents" means the
documents which at the time are incorporated by reference in the registration
statement, the Registration Statement, any Prepricing Prospectus, the
Prospectus, or any amendment or supplement thereto.

          It is understood that two forms of Prepricing Prospectus and two forms
of Prospectus are to be used in connection with the offering and sale of the
Underwritten Shares:  a Prepricing Prospectus and a Prospectus relating to the
Shares that are to be offered and sold in the United States (as defined herein)
or Canada (as defined herein) to U.S. or Canadian Persons (the "U.S. Prepricing
Prospectus" and the "U.S. Prospectus," respectively), and a Prepricing
Prospectus and a Prospectus relating to the International Shares which are to be
offered and sold outside the United States or Canada to persons other than U.S.
or Canadian Persons (the "International Prepricing Prospectus" and the
"International Prospectus," respectively).  The U.S. Prospectus and the
International Prospectus are herein collectively called the "Prospectuses," and
the U.S. Prepricing Prospectus and the International Prepricing Prospectus are
herein called the "Prepricing Prospectuses."  For purposes of this Agreement: 
"U.S. or Canadian Person" means any resident or national of the United States or
Canada, any corporation, partnership or other entity created or organized in or
under the laws of the United States or Canada or any estate or trust the income
of which is subject to United States or Canadian income taxation regardless of
the source of its income (other than the foreign branch of any U.S. or Canadian
Person), and includes any United States or Canadian branch of a person other
than a U.S. or Canadian Person; "United States" means the United States of
America (including the states thereof and the District of Columbia) and its
territories, its possessions and other areas subject to its jurisdiction; and
"Canada" means Canada and its territories, its possessions and other areas
subject to its jurisdiction.

     2.   AGREEMENTS TO SELL AND PURCHASE.  Upon the basis of the
representations, warranties and agreements contained herein and subject to all
the terms and conditions set forth herein and to such adjustments as you may
determine to avoid fractional shares, the Company hereby agrees to issue and
sell to each U.S. Underwriter and each U.S. Underwriter agrees, severally and
not jointly, to purchase from the Company, at a purchase price of $       per
share (the "purchase price per share"), the number of Firm Shares that bears the
same proportion to the aggregate number of Firm Shares to be issued and sold by
the Company as the number of Firm Shares set forth opposite the name of such
Underwriter in Schedule II hereto (or such number of Firm Shares increased as
set forth in Section 12 hereof) bears to the aggregate number of Firm Shares to
be sold by the Company and the Selling Stockholder. 

     Upon the basis of the representations, warranties and agreements 
contained herein and subject to all the terms and conditions set forth herein 
and to such adjustments as you may determine to avoid fractional shares, the 
Selling Stockholder agrees to sell to each U.S. Underwriter and each U.S. 
Underwriter agrees, severally and not jointly, to purchase from the Selling 
Stockholder, at the purchase price per share, the number of Firm Shares that 
bears the same proportion to the number of Firm Shares

                                       -3-

<PAGE>

set forth opposite the name of the Selling Stockholder in Schedule I hereto 
as the number of Firm Shares set forth opposite the name of such U.S. 
Underwriter in Schedule II hereto (or such number of Firm Shares increased as 
set forth in Section 12 hereof) bears to the aggregate number of Firm Shares 
to be sold by the Company and the Selling Stockholder. 

     Upon the basis of the representations, warranties and agreements contained
herein and subject to all the terms and conditions set forth herein, the Selling
Stockholder also agrees to sell to the U.S. Underwriters, and the U.S.
Underwriters shall have the right to purchase from the Selling Stockholder, at
the purchase price per share, pursuant to an option (the "over-allotment
option") which may be exercised prior to 5:00 p.m., New York City time, on the
30th day after the date of the U.S. Prospectus (or, if such 30th day shall be a
Saturday or Sunday or a holiday, on the next business day thereafter when the
New York Stock Exchange is open for trading), up to an aggregate of 1,200,000
Additional Shares from the Selling Stockholder.  Upon any exercise of the
over-allotment option, each U.S. Underwriter, severally and not jointly, agrees
to purchase from the Selling Stockholder the number of Additional Shares
(subject to such adjustments as you may determine in order to avoid fractional
shares) that bears the same proportion to the number of Additional Shares to be
sold by the Selling Stockholder as the number of Firm Shares set forth opposite
the name of such U.S. Underwriter in Schedule II hereto (or such number of Firm
Shares increased as set forth in Section 12 hereof) bears to the aggregate
number of Firm Shares to be sold by the Selling Stockholder.

          Each U.S Underwriter represents, warrants, covenants and agrees that,
except as contemplated under Section 2 of the Agreement Between U.S.
Underwriters and Managers dated the date hereof, (i) it is not purchasing any
Shares for the account of anyone other than a U.S. or Canadian Person, (ii) it
has not offered or sold, and will not offer, sell, resell or deliver, directly
or indirectly, any Shares or distribute any U.S. Prospectus outside the United
States or Canada or to anyone other than a U.S. or Canadian Person, and (iii)
any offer of Shares in Canada will be made only pursuant to an exemption from
the requirement to file a prospectus in the relevant province of Canada in which
such offer is made.

     3.   TERMS OF PUBLIC OFFERING.  The Sellers have been advised by you that
the U.S. Underwriters propose to make a public offering of their respective
portions of the Shares as soon after the Registration Statement and this
Agreement have become effective as in your judgment is advisable and initially

     5.   AGREEMENTS OF THE COMPANY.  The Company agrees with the several U.S.
Underwriters as follows:

          (a)  If, at the time this Agreement is executed and delivered, it is
necessary for the Registration Statement or a post-effective amendment thereto
or any Additional Registration Statement to be declared effective before the
offering of the Shares may commence, the Company will endeavor to cause the
Registration Statement or such post-effective amendment to become effective as
soon as possible and will advise you promptly and, if requested by you, will
confirm such advice in writing, when the Registration Statement or such
post-effective amendment or Additional Registration Statement has become
effective. 

          (b)  The Company will advise you promptly and, if requested by you,
will confirm such advice in writing:  (i) of any request by the Commission for
an amendment of or a supplement to the Registration Statement, any Prepricing
Prospectuses or the Prospectuses or for additional information; (ii) of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement or of the suspension of qualification of the Shares for
offering or sale in any jurisdiction or the initiation of any proceeding for
such purpose; and (iii) within the period of time referred to in paragraph (f)
below, of any change in the Company's condition (financial or other), business,
prospects, properties, net worth or results of operations, or of the happening
of any event, including the filing of any information, documents or reports
pursuant to the Exchange Act, that makes any statement made in the Registration
Statement or the Prospectuses (as then amended or supplemented) untrue in any
material respect or which requires the making of any additions to or changes in
the Registration Statement or the Prospectuses (as then amended or supplemented)
in order to state a material fact required by the Act or the regulations
thereunder to be stated therein or necessary in order to make the statements
therein not misleading, or of the necessity to amend or supplement the
Prospectuses (as then amended or supplemented) to comply with the Act or any
other law.  If at any time the Commission shall issue any stop order suspending
the effectiveness of the Registration Statement, the Company will make every
reasonable effort to obtain the withdrawal of such order at the earliest
possible time. 

          (c)  The Company will furnish to you, without charge, (i) seven signed
copies of the Registration Statement as originally filed with the Commission and
of each amendment thereto, including financial statements and all exhibits to
the Registration Statement, and (ii) such number of conformed copies of the
Registration Statement as originally filed and of each amendment thereto, but
without exhibits, and the Incorporated Documents thereto as you may request.

                                       -5-

<PAGE>

          (d)  The Company will not (i) file any amendment to the Registration
Statement or make any amendment or supplement to the Prospectuses or, prior to
the end of the period of time referred to in the first sentence in subsection
(f) below, file any document which, upon filing becomes an Incorporated
Document, of which you shall not previously have been advised or with respect to
which you shall not previously have been consulted or (ii) so long as, in the
opinion of counsel for the U.S. Underwriters, a prospectus is required to be
delivered in connection with sales by any U.S. Underwriter or dealer, file any
information, documents or reports pursuant to the Exchange Act, without
delivering a copy of such information, documents or reports to you, as
Representatives of the U.S. Underwriters, prior to or concurrently with such
filing.
  
          (e)  Prior to the execution and delivery of this Agreement, the
Company has delivered or will deliver to you, without charge, in such quantities
as you have reasonably requested or may hereafter request, copies of each U.S.
Prepricing Prospectus.  The Company consents to the use, in accordance with the
provisions of the Act and with the securities or Blue Sky laws of the
jurisdictions in which the Shares are offered by the several U.S. Underwriters
and by dealers, prior to the date of the U.S. Prospectus, of each U.S.
Prepricing Prospectus so furnished by the Company. 

          (f)  As soon after the execution and delivery of this Agreement as
possible and thereafter from time to time for such period as in the written
opinion of counsel for the U.S. Underwriters a U.S. Prospectus is required by
the Act to be delivered in connection with sales by any U.S. Underwriter or
dealer, the Company will expeditiously deliver to each U.S. Underwriter and each
dealer, without charge, as many copies of the U.S. Prospectus (and of any
amendment or supplement thereto) as you may reasonably request.  The Company
consents to the use of the U.S. Prospectus (and of any amendment or supplement
thereto) in accordance with the provisions of the Act and with the securities or
Blue Sky laws of the jurisdictions in which the Shares are offered by the
several U.S. Underwriters and by all dealers to whom Shares may be sold, both in
connection with the offering and sale of the Shares and for such period of time
thereafter as the U.S. Prospectus is required by the Act to be delivered in
connection with sales by any U.S. Underwriter or dealer.  If during such period
of time any event shall occur that in the judgment of the Company or in the
opinion of counsel for the U.S. Underwriters is required to be set forth in the
U.S. Prospectus (as then amended or supplemented) or should be set forth therein
in order to make the statements therein, in the light of the circumstances under
which they were made, not misleading, or if it is necessary to supplement or
amend the U.S. Prospectus (or to file under the Exchange Act any document which,
upon filing, becomes an Incorporated Document) to comply with the Act, the
Exchange Act or any other law, the Company will forthwith prepare and, subject
to the provisions of paragraph (d) above, file with the Commission an
appropriate supplement or amendment thereto or such document, and will
expeditiously furnish to the U.S. Underwriters and dealers a reasonable number
of copies thereof.  In the event that the Company and you, as Representatives of
the several U.S. Underwriters, agree that either of the Prospectuses should be
amended or supplemented, or that a document should be filed under the Exchange
Act which upon filing becomes an Incorporated Document, the Company, if
requested by you, will promptly issue a press release announcing or disclosing

business as described in the Registration Statement and the Prospectuses, and is
duly registered and qualified to conduct its business and is in good standing in
each jurisdiction where the nature of its properties or the conduct of its

results of operations of the Company and the Subsidiaries (as hereinafter
defined) taken as a whole (a "Material Adverse Effect").

          (f)  All the Company's subsidiaries (collectively, the "Subsidiaries")

proceedings or investigations pending or, to the knowledge of the Company,
threatened, against the Company or any of the Subsidiaries or against or
involving any of its officers, directors or employees in connection with the
business or affairs of the Company, including, without limitation, any claims
for indemnification arising under any agreement to which the Company is a party,
or to which the Company or any of the Subsidiaries or any of their respective

Company is not subject to or in default with respect to any writ, order,
judgment, injunction or decree which could have a Material Adverse Effect.

          (h)  Neither the Company nor any of the Subsidiaries is in (i)

Material Adverse Effect), or (iii) in default in any material respect in the
performance of any obligation, agreement or condition contained in any bond,
debenture, note or any other evidence of indebtedness or in any material
agreement, indenture, lease or other instrument to which the Company or

any of the Subsidiaries is a party or by which any of them or any of their
respective properties may be bound, and no condition or state of facts exists,
which with the passage of time or the giving of notice or both, would constitute
such a default (except where any such default or defaults in the aggregate would
not have a Material Adverse Effect). 

          (i)  Neither the issuance, offer, sale or delivery of the Shares, the
execution, delivery or performance of this Agreement or the International
Underwriting Agreement by the Company nor the consummation by the Company of the
transactions contemplated hereby and thereby (i) requires any consent, approval,

or violation which could not have a Material Adverse Effect, or (iii) will
result in the creation or imposition of any lien, charge or encumbrance upon any
property or assets of the Company or any of the Subsidiaries pursuant to the

forma financial information included in or incorporated by reference into the 
Registration Statement and the Prospectuses are reasonable, and the 
adjustments used therein are reasonably appropriate to give effect to the 
transactions or circumstances referred to therein.

          (l)  The execution and delivery of, and the performance by the Company
of its obligations under, each of this Agreement and the International

any development having or which may reasonably be expected to have, a Material
Adverse Effect. 

          (n)  Each of the Company and the Subsidiaries has good and marketable
title to all property (real and personal) described in the Prospectuses as being

encumbrances except such as are described in the Registration Statement and the
Prospectuses or in a document filed as an exhibit to the Registration Statement
and all the property described in the Prospectuses as being held under lease by
each of the Company and the Subsidiaries is held by it under valid, subsisting

Subsidiary that participate in Medicare and/or Medicaid, to receive
reimbursement thereunder, and (z) under such insurance laws and regulations
which are applicable to the Company or any of the Subsidiaries, except where the
failure to have any such Permit would not have a Material Adverse Effect and
subject to such qualifications as may be set forth in the Prospectuses; the
Company and each of the Subsidiaries has fulfilled and performed all its
material obligations with respect to such Permits and no event has occurred that
allows, or after notice or lapse of time would allow, revocation or termination
thereof or results in any other material impairment of the rights of the holder
of any such Permit, subject in each case to such qualification as may be set
forth in the Prospectuses; and, except as described in the Prospectuses, none of
such Permits contains any restriction that is materially burdensome to the
Company or any of the Subsidiaries. 

          (q)  The Company maintains a system of internal accounting controls

transactions contemplated by this Agreement or the International Underwriting
Agreement, or otherwise.  No such rights with respect to shares of Common Stock
not listed in Schedule I or Schedule II hereto were exercised nor will be
exercised in connection with the sale of the Shares and for a period of 90 days
after the date hereof.  Except as described in or contemplated by the

release into the environment of any substance regulated by, or form the basis of
liability under, any Environmental Laws (a "Hazardous Material") or is in
contravention of any federal, state, local or foreign law, order or regulation

Subsidiaries has received any notice or claim, nor are there pending threatened
or reasonably anticipated lawsuits against it with respect to violations of an
Environmental Law or in connection with the release or threatened release of any
Hazardous Material into the environment.  To the best of the Company's

contingent liability in connection with any release or threatened release of
Hazardous Material into the environment.

governmental body, agency or official (except such as may be required for the
registration of the Shares under the Act or compliance with the securities or
Blue Sky laws of various jurisdictions or except as already obtained), or (ii)
conflicts or will conflict with or constitutes or will constitute a breach of,
or a default under, any agreement, indenture, lease or other instrument to which
the Selling Stockholder is a party or by which the Selling Stockholder is or may
be bound, or violates or will violate any statute, law, regulation or filing or
judgment, injunction, order or decree applicable to the Selling Stockholder, or
will result in the creation or imposition of any lien, charge or encumbrance
upon any property or assets of the Selling Stockholder pursuant to the terms of
any agreement or instrument to which the Selling Stockholder is a party or by
which the Selling Stockholder may be bound or to which any of the property or
assets of the Selling Stockholder is subject.

          (e)  The information pertaining to the Selling Stockholder provided to
the Company for inclusion under the caption "Principal and Selling Stockholders"
in the Prospectuses, does not and will not contain an untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein not misleading. 

          (f)  The Selling Stockholder has not taken, directly or indirectly,
any action designed to or that might reasonably be expected to cause or result
in stabilization or manipulation of the price of the Common Stock to facilitate
the sale or resale of the Shares, except for the lock-up arrangements referred
to in the Prospectuses.

          (g)  The Selling Stockholder does not have any knowledge or any reason
to believe that the Registration Statement or the Prospectuses (or any amendment
or supplement thereto) contains any untrue statement of a material fact or omits
to state any material fact required to be stated therein or necessary to make
the statements therein not misleading.

     9.   INDEMNIFICATION AND CONTRIBUTION.  (a)  The Company and the Selling
Stockholder, jointly and severally, agree to indemnify and hold harmless you and
each other U.S. Underwriter and each person, if any, who controls any U.S.
Underwriter within the meaning of Section 15 of the Act or Section 20(a) of the
Exchange Act from and against any and all losses, claims, damages, liabilities
and expenses (including reasonable costs of investigation) arising out of or
based upon any untrue statement or alleged untrue statement of a material fact
contained in any U.S. Prepricing Prospectus or in the Registration Statement or
the U.S. Prospectus or in any amendment or supplement thereto, or arising out of
or based upon any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, except insofar as such losses, claims, damages, liabilities or
expenses arise out of or are based upon any untrue statement or omission or
alleged untrue statement or omission which has been made therein or omitted
therefrom in reliance upon and in conformity with the information relating to
such U.S. Underwriter or Manager furnished in writing to the Company by or on
behalf of any U.S. Underwriter through you as Representatives of the several
U.S. Underwriters or by or on behalf of any Manager through a Lead Manager
expressly for use in connection therewith; provided, that with respect to the
Selling Stockholder, only to the extent that any such loss, liability, claim,
damage or expense arises out of or is based upon any untrue statement or alleged
untrue statement or an omission or alleged omission made therein in reliance
upon and in conformity with written information relating to the Selling
Stockholder furnished to the Company or the U.S. Underwriters by the Selling
Stockholder expressly for use in any Prepricing Prospectus or in the
Registration Statement or the U.S. Prospectus or in any amendment or supplement
thereto; provided, further, however, that the indemnification contained in this
paragraph (a) with respect to any U.S. Prepricing Prospectus shall not inure to
the benefit of any U.S. Underwriter (or to the benefit of any person controlling
such U.S. Underwriter) on account of any such loss, claim, damage, liability or
expense arising from the sale of the Shares by such U.S. Underwriter to any
person if a copy of the U.S. Prospectus shall not have been delivered or sent to
such person within the time required by the Act and the regulations thereunder,
and the untrue statement or alleged untrue statement or omission or alleged
omission of a material fact contained in such U.S. Prepricing Prospectus was
corrected in the U.S. Prospectus, provided that the Company has delivered the
U.S. Prospectus to the several U.S. Underwriters in a reasonable quantity on a
timely basis to permit such delivery or sending.  The foregoing indemnity
agreement shall be in addition to any liability which the Company or the Selling
Stockholder may otherwise have. 

          (b)  If any action, suit or proceeding shall be brought against any
U.S. Underwriter or any person controlling any U.S. Underwriter in respect of
which indemnity may be sought against the Company or the Selling Stockholder,
such U.S. Underwriter or such controlling person shall promptly notify the
parties against whom indemnification is being sought (the "indemnifying
parties"), and such indemnifying parties shall assume the defense thereof,
including the employment of counsel and payment of all fees and expenses.  Such
U.S. Underwriter or any such controlling person shall have the right to employ
separate counsel in any such action, suit or proceeding and to participate in
the defense thereof, but the fees and expenses of such counsel shall be at the
expense of such U.S. Underwriter or such controlling person unless (i) the
indemnifying parties have agreed in writing to pay such fees and expenses, (ii)
the indemnifying parties have failed to assume the defense and employ counsel,
or (iii) the named parties to any such action, suit or proceeding (including any
impleaded parties) include both such U.S. Underwriter or such controlling person
and the indemnifying parties and such U.S. Underwriter or such controlling
person shall have been advised by its counsel in writing that representation of
such indemnified party and any indemnifying party by the same counsel would be
inappropriate under applicable standards of professional conduct (whether or not
such representation by the same counsel has been proposed) due to actual or
potential differing interests between them (in which case the indemnifying party
shall not have

                                      -16-

<PAGE>

the right to assume the defense of such action, suit or proceeding on behalf of
such U.S. Underwriter or such controlling person).  It is understood, however,
that the indemnifying parties shall, in connection with any one such action,
suit or proceeding or separate but substantially similar or related actions,
suits or proceedings in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the reasonable fees and expenses of
only one separate firm of attorneys (in addition to any local counsel) at any
time for all such U.S. Underwriters and controlling persons not having actual or
potential differing interests with you or among themselves, which firm shall be
designated in writing by Smith Barney Inc., and that all such fees and expenses
shall be reimbursed as they are incurred.  The indemnifying parties shall not be
liable for any settlement of any such action, suit or proceeding effected
without their written consent, but if settled with such written consent, or if
there be a final judgment for the plaintiff in any such action, suit or
proceeding, the indemnifying parties agree to indemnify and hold harmless any
U.S. Underwriter, to the extent provided in the preceding paragraph, and any
such controlling person from and against any loss, claim, damage, liability or
expense by reason of such settlement or judgment. 

          (c)  Each U.S. Underwriter agrees, severally and not jointly, to
indemnify and hold harmless the Company, its directors, its officers who sign
the Registration Statement, any person who controls the Company within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act and the
Selling Stockholder, to the same extent as the foregoing indemnity from the
Company and the Selling Stockholder to each U.S. Underwriter, but only with
respect to information relating to such U.S. Underwriter furnished in writing by
or on behalf of such U.S. Underwriter through you expressly for use in the
Registration Statement, the U.S. Prospectus or any U.S. Prepricing Prospectus,
or any amendment or supplement thereto.  If any action, suit or proceeding shall
be brought against the Company, any of its directors, any such officer, any such
controlling person or the Selling Stockholder based on the Registration
Statement, the U.S. Prospectus or any U.S. Prepricing Prospectus, or any
amendment or supplement thereto, and in respect of which indemnity may be sought
against any U.S. Underwriter pursuant to this paragraph (c), such U.S.
Underwriter shall have the rights and duties given to the Company and the
Selling Stockholder by paragraph (b) above (except that if the Company or the
Selling Stockholder shall have assumed the defense thereof such U.S. Underwriter
shall not be required to do so, but may employ separate counsel therein and
participate in the defense thereof, but the fees and expenses of such counsel
shall be at such U.S. Underwriter's expense), and the Company, its directors,
any such officer, any such controlling person, and the Selling Stockholder,
shall have the rights and duties given to the U.S. Underwriters by paragraph (b)
above.  The foregoing indemnity agreement shall be in addition to any liability
which the U.S. Underwriters may otherwise have. 

          (d)  If the indemnification provided for in this Section 9 is
unavailable to an indemnified party under paragraphs (a) or (c) hereof in
respect of any losses, claims, damages, liabilities or expenses referred to
therein, then an indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party
as a result of such losses, claims, damages, liabilities or expenses (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company and the Selling Stockholder on the one hand and the U.S. Underwriters on
the other hand from the offering of the Shares, or (ii) if the allocation
provided by clause (i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of the Company and the
Selling Stockholder on the one hand and the U.S. Underwriters on the other hand
in connection with the statements or omissions that resulted in such losses,
claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations.  The relative benefits received by the Company and the
Selling Stockholder on the one hand

                                      -17-

<PAGE>

and the U.S. Underwriters on the other hand shall be deemed to be in the same
proportion as the total net proceeds from the offering (before deducting
expenses) received by the Company and the Selling Stockholder bear to the total
underwriting discounts and commissions received by the U.S. Underwriters, in
each case as set forth in the table on the cover page of the U.S. Prospectus;
provided that, in the event that the U.S. Underwriters shall have purchased any
Additional Shares hereunder, any determination of the relative benefits received
by the Company, the Selling Stockholder or the U.S. Underwriters from the
offering of the Shares shall include the net proceeds (before deducting
expenses) received by the Selling Stockholder, and the underwriting discounts
and commissions received by the U.S. Underwriters, from the sale of such
Additional Shares, in each case computed on the basis of the respective amounts
set forth in the notes to the table on the cover page of the U.S. Prospectus. 
The relative fault of the Company and the Selling Stockholder on the one hand
and the U.S. Underwriters 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 supplied by the Company or the Selling Stockholder on the one hand
or by the U.S. Underwriters on the other hand and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. 

          (e)  The Company, the Selling Stockholder and the U.S. Underwriters
agree that it would not be just and equitable if contribution pursuant to this
Section 9 were determined by a pro rata allocation (even if the U.S.
Underwriters were treated as one entity for such purpose) or by any other method
of allocation that does not take account of the equitable considerations
referred to in paragraph (d) above.  The amount paid or payable by an
indemnified party as a result of the losses, claims, damages, liabilities and
expenses referred to in paragraph (d) above shall be deemed to include, subject
to the limitations set forth above, any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating any claim or
defending any such action, suit or proceeding.  Notwithstanding the provisions
of this Section 9, no U.S. Underwriter shall be required to contribute any
amount in excess of the amount by which the total price of the Shares
underwritten by it and distributed to the public exceeds the amount of any
damages which such U.S. Underwriter has otherwise been required to pay by reason
of such untrue or alleged untrue statement or omission or alleged omission. 
Notwithstanding the provisions of this Section 9, the Selling Stockholder shall
not be required to contribute any amount in excess of the aggregate proceeds
received by such Selling Stockholder from the sale of its Shares pursuant to
this Agreement (net of underwriting discounts and commissions and after
deducting expenses).  No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.  The U.S.
Underwriters' obligations to contribute pursuant to this Section 9 are several
in proportion to the respective numbers of Firm Shares set forth opposite their
names in Schedule II hereto (or such numbers of Firm Shares increased as set
forth in Section 12 hereof) and not joint. 

          (f)  No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement of any pending or threatened
action, suit or proceeding in respect of which any indemnified party is or could
have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such action, suit or proceeding.

          (g)  Any losses, claims, damages, liabilities or expenses for which an
indemnified party is entitled to indemnification or contribution under this
Section 9 shall be paid by the indemnifying party to the indemnified party as
such losses, claims, damages, liabilities or expenses are incurred.  The 

                                      -18-

<PAGE>

indemnity and contribution agreements contained in this Section 9 and the
representations and warranties of the Company and the Selling Stockholder set
forth in this Agreement shall remain operative and in full force and effect,
regardless of (i) any investigation made by or on behalf of any U.S. Underwriter
or any person controlling any U.S. Underwriter, the Company, its directors or
officers or the Selling Stockholder, any director, officer or partner of the
Selling Stockholder or any person controlling the Company or the Selling
Stockholder, (ii) acceptance of any Shares and payment therefor hereunder, and
(iii) any termination of this Agreement.  A successor to any U.S. Underwriter or
any person controlling any U.S. Underwriter, or to the Company, its directors or
officers, or to the Selling Stockholder, any director, officer or partner of the
Selling Stockholder or any person controlling the Company or the Selling
Stockholder, shall be entitled to the benefits of the indemnity, contribution
and reimbursement agreements contained in this Section 9.

     10.  CONDITIONS OF U.S. UNDERWRITERS' OBLIGATIONS.  The several obligations
of the U.S. Underwriters to purchase the Firm Shares hereunder are subject to
the following conditions:

          (a)  If, at the time this Agreement is executed and delivered, it is
necessary for the Registration Statement or a post-effective amendment thereto
or an Additional Registration Statement to be declared effective before the
offering of the Shares may commence, the Registration Statement or such
post-effective amendment or Additional Registration Statement shall have become
effective not later than 5:30 P.M., New York City time, on the date hereof, or
at such later date and time as shall be consented to in writing by you, and all
filings, if any, required by Rules 424 and 430A under the Act shall have been
timely made; no stop order suspending the effectiveness of the Registration
Statement shall have been issued and no proceeding for that purpose shall have
been instituted or, to the knowledge of the Company or any U.S. Underwriter,
threatened by the Commission, and any request of the Commission for additional
information (to be included in the Registration Statement or the Prospectuses or
otherwise) shall have been complied with to your satisfaction. 

          (b)  Subsequent to the effective date of this Agreement, there shall
not have occurred any change, or any development involving a prospective change,
that would have a Material Adverse Effect on the Company and the Subsidiaries,
taken as a whole, not contemplated by the Prospectuses, which in your opinion,
as Representatives of the several U.S. Underwriters, makes it impracticable or
inadvisable to proceed with an offering of the Shares.

          (c)  You shall have received on the Closing Date an opinion of the B.
Curtis Westen, Senior Vice President, General Counsel and Secretary for the
Company dated the Closing Date and addressed to you, as Representatives of the
several U.S. Underwriters, to the effect that:

               (i)      Each Subsidiary is a corporation duly organized and
validly existing and in good standing under the laws of the jurisdiction of its
organization, with full power and authority to own, lease, and operate its
properties and to conduct its business as described in the Registration
Statement and the Prospectuses (and any amendment or supplement thereto); and
all the outstanding shares of capital stock of each of the Subsidiaries have
been duly authorized and validly issued, are fully paid and nonassessable, and
are owned of record by the Company directly, or indirectly through one of the
other Subsidiaries, free and clear of any security interest, lien, adverse
claim, equity or other encumbrance, except as referred to in the Registration
Statement and the Prospectuses (or any amendment or supplement thereto);

                                      -19-

<PAGE>

               (ii)      The Company and each Subsidiary is duly registered and
qualified to conduct its business and is in good standing as a foreign
corporation in each jurisdiction where the nature of its properties or the
conduct of its business requires such registration or qualification, except
where the failure so to register or qualify or to be in good standing does not
have a Material Adverse Effect;

               (iii)     All the shares of capital stock of the Company
outstanding prior to the issuance of the Shares have been duly authorized and
validly issued and are fully paid and nonassessable;

               (iv)      Neither the Company nor any of the Subsidiaries is (a)
in violation of its certificate of incorporation or bylaws, or other
organizational documents, nor (b) is in material default in the performance of
any material obligation, agreement or condition contained in any bond,
debenture, note or other evidence of indebtedness, except as disclosed in the
Registration Statement or Prospectuses (or any amendment or supplement thereto);

               (v)       Neither the offer, sale or delivery of the Shares, nor
the execution, delivery or performance of the U.S. Underwriting Agreement or the
International Underwriting Agreement, nor compliance by the Company with the
provisions thereof, nor consummation by the Company of the transactions
contemplated thereby conflicts or will conflict with or constitutes or will
constitute a breach of, or a default under, in any material respect, the
certificate of incorporation or bylaws, or other organizational documents of the
Company or any of the Subsidiaries or any agreement, indenture, lease or other
instrument to which the Company or any of the Subsidiaries is a party or by
which any of them or any of their respective properties is bound that is made an
exhibit to the Registration Statement or to any Incorporated Document, or is
known to such counsel after reasonable inquiry, or will result in the creation
or imposition of any lien, charge or encumbrance upon any property or assets of
the Company or any of the Subsidiaries, nor will any such action result in any
violation of any existing law, regulation, ruling (assuming compliance with all
applicable state securities and Blue Sky laws), judgment, injunction, order or
decree known to such counsel after reasonable inquiry, and applicable to the
Company, the Subsidiaries, or any of their respective properties, except where
any of the foregoing would not have a Material Adverse Effect;

               (vi)      Each of the Company and each Subsidiary has full
corporate power and authority and, to such counsel's knowledge after reasonable
inquiry, such Permits as are required, (A) under such federal and state
healthcare laws as are applicable to the Company or any of the Subsidiaries to
own, lease and operate their respective properties and to conduct their
respective businesses as described in the Prospectuses, and (B) with respect to
those facilities owned, leased or managed by the Company or any Subsidiary that
participates in Medicare and/or Medicaid, to receive reimbursement thereunder,
except where the failure to so possess any such Permits would not, singularly or
in the aggregate, have a Material Adverse Effect; 

               (vii)     To the knowledge of such counsel, neither the Company
nor any of the Subsidiaries is in violation of any healthcare law, ordinance,
administrative or governmental rule or regulation applicable to them,
respectively,  or of any decree of any court or governmental agency or body
having jurisdiction over them relating thereto, respectively, and, in the course
of such counsel's representation of the Company or any Subsidiary, nothing has
come to such counsel's attention to cause it to believe that the Company or any
Subsidiary is in violation of any other law, ordinance, administrative or
governmental rule or regulation applicable to it or of any decree of any court
or governmental agency or body having jurisdiction over it which could have a
Material Adverse Effect; 

                                      -20-

<PAGE>

               (viii)    There are no legal or governmental actions, suits,
claims, proceedings or investigations pending or, to the knowledge of the
Company, threatened, against the Company or any of the Subsidiaries or against
or involving any of its officers, directors or employees in connection with the
business or affairs of the Company, including, without limitation, any claims
for indemnification arising under any agreement to which the Company is a party,
which are materially adverse to the Company or any of its Subsidiaries, or to
which the Company or any of the Subsidiaries, or to which any of their
respective properties, is subject which are material to the Company and its
Subsidiaries, taken as a whole (including, without limitation, any proceeding to
revoke or deny renewal of any Permits (as defined herein) of the Company or any
of the Subsidiaries), that are required to be described in the Registration
Statement or the Prospectuses but are not described as required, and there are
no agreements, contracts, indentures, leases or other instruments relating to
the Company that are required to be described in the Registration Statement or
the Prospectuses or to be filed as an exhibit to the Registration Statement or
any Incorporated Document that are not described or filed as required by the Act
or the Exchange Act.  The descriptions of the terms of any such contracts or
documents contained in the Registration Statement or the Prospectuses are
accurate in all material respects.   The Company is not subject to or in default
with respect to any writ, order, judgment, injunction or decree which is
materially adverse to the Company or any of its Subsidiaries; 

               (ix)      Each of the Incorporated Documents (except for the
financial statements and the notes thereto and the schedules and other financial
and statistical data included therein, as to which counsel need not express any
opinion) complies as to form in all material respects with the Exchange Act and
the rules and regulations of the Commission thereunder; and

               (x)       The statements in the Registration Statement and
Prospectuses or any Incorporated Document, insofar as they are descriptions of
contracts, agreements or other legal documents, or refer to statements of law or
legal conclusions, are accurate in all material respects and present fairly the
information required to be shown.

          In addition, such counsel shall state that although such counsel has
not undertaken, except as otherwise indicated in his opinion, to determine
independently, and does not assume any responsibility for, the accuracy,
completeness or fairness of the statements in the Registration Statement, such
counsel has participated in the preparation of the Registration Statement and
the Prospectuses, including review and discussion of the contents thereof
(including review and discussion of the contents of all Incorporated Documents),
and no facts have come to the attention of such counsel that would lead him to
believe that the Registration Statement (including the Incorporated Documents)
at the time the Registration Statement became effective, or the Prospectuses as
of their respective dates and as of the Closing Date or the Option Closing Date,
as the case may be, contained an untrue statement of a material fact or omitted
or omits to state a material fact necessary in order to make the statements
therein not misleading or that any amendment or supplement to the Prospectuses,
as of its respective date, and as of the Closing Date or the Option Closing
Date, as the case may be, contained or contains an untrue statement of a
material fact or omitted or omits to state a material fact required to be stated
in the Prospectuses or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading (it being
understood that such counsel need express no opinion with respect to the
financial statements and the notes thereto and the schedules and other financial
and statistical data included in the Registration Statement or the Prospectuses
or in any Incorporated Documents).

                                      -21-

<PAGE>

          In rendering such opinion as aforesaid, such counsel may, as to
matters of law, rely upon an opinion or opinions, each dated the Closing Date,
of other counsel retained by him or the Company as to laws of any jurisdiction
other than the United States or the State of California or the corporation law
of the State of Delaware, provided that (1) each such local counsel is
reasonably acceptable to the Representatives, (2) such reliance is expressly
authorized by each opinion so relied upon and a copy of each such opinion is
delivered to the Representatives and is, in form and substance reasonably
satisfactory to them and their counsel, and (3) such counsel shall state in his
opinion that he believes that they and the U.S. Underwriters are justified in
relying thereon.

          (d)  You shall have received on the Closing Date an opinion from
McDermott, Will & Emery, Special Counsel to the Company, dated the Closing Date
and addressed to you, as Representatives of the several U.S. Underwriters, to
the effect that:

               (i)       The Company is a corporation duly organized and validly
existing in good standing under the laws of the State of Delaware with full
corporate power and authority to own, lease and operate its properties and to
conduct its business as described in the Registration Statement and the
Prospectuses;

               (ii)      The authorized capital stock of the Company is as set
forth under the caption "Capitalization" in the Prospectuses; and, the
authorized capital stock of the Company conforms in all material respects as to
legal matters to the description thereof contained in the Prospectuses under the
caption "Description of Capital Stock";

               (iii)     The Shares to be issued and sold to the U.S.
Underwriters and Managers by the Company pursuant to the U.S. Underwriting
Agreement and the International Underwriting Agreement have been duly authorized
and, when issued and delivered to the U.S. Underwriters and Managers against
payment therefor in accordance with the terms of the U.S. Underwriting Agreement
and the International Underwriting Agreement will be validly issued, fully paid
and nonassessable and free of any (A) preemptive rights or (B) to the best
knowledge of such counsel after reasonable inquiry, similar rights that entitle
or will entitle any person to acquire any Shares upon the issuance thereof by
the Company;

               (iv)      The form of certificates for the Shares conforms to the
requirements of the Delaware General Corporation Law;

               (v)       The Registration Statement and all post-effective
amendments, if any, have become effective under the Act and, to the best
knowledge of such counsel after reasonable inquiry, no stop order suspending the
effectiveness of the Registration Statement has been issued and no proceedings
for that purpose are pending before or contemplated by the Commission; and any
required filing of the Prospectuses pursuant to Rule 424(b) has been made in
accordance with Rule 424(b);

               (vi)      The Company has the corporate power and authority to
enter into the U.S. Underwriting Agreement and the International Underwriting
Agreement and to issue, sell and deliver the Shares to be sold by it to the U.S.
Underwriters and Managers as provided therein, and each of the U.S. Underwriting
Agreement and the International Underwriting Agreement have been duly
authorized, executed and delivered by the Company and is a legal, valid and
binding agreement of the Company, enforceable against the Company in accordance
with its terms, except as enforcement of rights to indemnity

                                      -22-

<PAGE>

and contribution hereunder may be limited by federal or state securities laws or
principles of public policy and subject to the qualification that the
enforceability of the Company's obligations hereunder may be limited by
bankruptcy, fraudulent conveyance, insolvency, reorganization, moratorium and
other laws relating to or affecting creditors' rights generally and by general
equitable principles;

               (vii)     No consent, approval, authorization or other order of,
or registration or filing with, any court, regulatory body, administrative
agency or other governmental body, agency, or official is required on the part
of the Company (except as have been obtained under the Act and the Exchange Act
or such as may be required under state securities or Blue Sky laws governing the
purchase and distribution of the Shares) for the valid issuance and sale of the
Shares to the U.S. Underwriters as contemplated by the U.S. Underwriting
Agreement; 

               (viii)    (A) The Registration Statement and the Prospectuses and
any supplements or amendments thereto (except for the financial statements and
notes thereto and the schedules and other financial and statistical data
included therein, as to which such counsel need not express any opinion) comply
as to form in all material respects with the requirements of the Act; and (B)

Prospectuses, such counsel does not know of any outstanding option, warrant or
other right calling for the issuance of, and such counsel does not know of any

exercise of options under the Company's stock option plans described in the
Prospectus); and except as described in the Prospectuses, such counsel does not
know of any holder of any security of the Company or any other person who has
the right, contractual or otherwise, to cause the Company to sell or otherwise

the right (other than any such right which has been complied with by the Company

within the meaning of the Investment Company Act of 1940, as amended.

          In addition, such counsel shall state that although such counsel has
not undertaken, except as otherwise indicated in their opinion, to determine
independently, and does not assume any responsibility for, the accuracy,
completeness or fairness of the statements in the Registration Statement, such
counsel has participated in the preparation of the Registration Statement and
the Prospectuses, including review and

                                      -23-

<PAGE>

discussion of the contents thereof (including review and discussion of the
contents of all Incorporated Documents), and no facts have come to the attention
of such counsel that would lead them to believe that the Registration Statement
(including the Incorporated Documents) at the time the Registration Statement
became effective, or the Prospectuses as of their respective dates and as of the
Closing Date or the Option Closing Date, as the case may be, contained an untrue
statement of a material fact or omitted or omits to state a material fact
necessary in order to make the statements therein not misleading or that any
amendment or supplement to the Prospectuses, as of its respective date, and as
of the Closing Date or the Option Closing Date, as the case may be, contained or
contains an untrue statement of a material fact or omitted or omits to state a
material fact required to be stated in the Prospectuses or necessary in order to
make the statements therein, in light of the circumstances under which they were
made, not misleading (it being understood that such counsel need express no
opinion with respect to the financial statements and the notes thereto and the
schedules and other financial and statistical data included in the Registration
Statement or the Prospectuses or in any Incorporated Documents).

          The opinion of such counsel may be limited to the laws of the United
States and the State of New York, State of California, the corporation laws of
the State of Delaware, and to the laws of certain other jurisdictions applicable
to the Company or a Subsidiary to the extent covered by an opinion or opinions,
each dated the Closing Date or the Option Closing Date, as the case may be, of
other counsel retained by them or the Company as to the laws of such other
jurisdiction, upon which such counsel may rely, provided that (1) each such
local counsel is acceptable to the Representatives, (2) such reliance is
expressly authorized by each opinion so relied upon and a copy of each such
opinion is delivered to the Representatives and is, in form and substance
satisfactory to them and their counsel, and (3) counsel shall state in their
opinion that they believe that they and the U.S. Underwriters are justified in
relying thereon.

          (e)  You shall have received on the Closing Date an opinion of Manatt,
Phelps & Phillips, LLP, special counsel for the Selling Stockholder, dated the
Closing Date and addressed to you, as Representatives of the several U.S.
Underwriters, to the effect that:

               (i)    The U.S. Underwriting Agreement and the International
Underwriting Agreement have each been duly executed and delivered by or on
behalf of the Selling Stockholder and are valid and binding agreements of the
Selling Stockholder enforceable against the Selling Stockholder in accordance
with their respective terms, except (A) as enforcement of rights to indemnity
and contribution hereunder and thereunder may be limited by federal or state
securities laws or principles of public policy and (B) subject to the
qualification that the enforceability of each of their obligations hereunder and
thereunder may be limited by bankruptcy, fraudulent conveyance, insolvency,
reorganization, moratorium and other laws relating to or affecting creditors'
rights generally and by general equitable principles;

               (ii)   To the knowledge of such counsel, the Selling Stockholder
has full legal right, power and authorization and any approval required by law
to sell, assign, transfer and deliver good and marketable title to the Shares
the Selling Stockholder has agreed to sell pursuant to this Agreement; and upon
delivery of such Shares pursuant to the U.S. Underwriting Agreement and the
International Underwriting Agreement and payment therefor as contemplated herein
and assuming that the several U.S. Underwriters and Managers are bona fide
purchasers within the meaning of the Uniform Commercial Code as in effect in the
State of New York (the "UCC"), the U.S. Underwriters will acquire good and
marketable title to such Shares free and clear of any adverse claim (within the
meaning of Section 8-302 of the U.C.C.); and

                                      -24-

<PAGE>

               (iii)     To the knowledge of such counsel, the execution and
delivery of the U.S. Underwriting Agreement and the International Underwriting
Agreement by the Selling Stockholder and the consummation of the transactions
contemplated hereby and thereby will not conflict with, violate, result in a
breach of or constitute a default under the terms or provisions of any
agreement, indenture, mortgage or other instrument to which the Selling
Stockholder is a party or by which it or any of its assets or property is bound,
or any court order or decree or any law, rule, or regulation known to such
counsel applicable to the Selling Stockholder or to any of the respective
property or assets of the Selling Stockholder.

          In addition, such counsel shall state that although such counsel has
not undertaken, except as otherwise indicated in their opinion, to determine
independently, and does not assume any responsibility for, the accuracy,
completeness or fairness of the statements in the Registration Statement with
respect to the Selling Stockholder, such counsel has participated in the
preparation of the Registration Statement and the Prospectuses, including review
and discussion of the contents thereof (including review and discussion of the
contents of all Incorporated Documents with respect to the Selling Stockholder),
and no facts have come to the attention of such counsel that would lead them to
believe that, insofar as such relates to the Selling Stockholder, the
Registration Statement (including the Incorporated Documents) at the time the
Registration Statement became effective, or the Prospectuses as of their
respective dates and as of the Closing Date or the Option Closing Date, as the
case may be, contained an untrue statement of a material fact or omitted or
omits to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading or that any amendment or supplement to the Prospectuses, as of its
respective date, and as of the Closing Date or the Option Closing Date, as the
case may be, contained or contains an untrue statement of a material fact or
omitted or omits to state a material fact required to be stated in the
Prospectuses or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading (it being
understood that such counsel need express no opinion with respect to the
financial statements and the notes thereto and the schedules and other financial
and statistical data included in the Registration Statement or the Prospectuses
or in any Incorporated Documents or any other information regarding the
Company).

          The opinion of such counsel may be limited to the laws of the United
States and the State of California, the corporation laws of the State of
Delaware, and to the laws of certain other jurisdictions applicable to the
Selling Stockholder to the extent covered by an opinion or opinions, each dated
the Closing Date or the Option Closing Date, as the case may be, of other
counsel retained by them or the Company as to the laws of such other
jurisdiction, upon which such counsel may rely, provided that (1) each such
local counsel is acceptable to the Representatives, (2) such reliance is
expressly authorized by each opinion so relied upon and a copy of each such
opinion is delivered to the Representatives and is, in form and substance
satisfactory to them and their counsel, and (3) counsel shall state in their
opinion that they believe that they and the U.S. Underwriters are justified in
relying thereon.

          (f)  You shall have received on the Closing Date an opinion of Dewey
Ballantine, counsel for the U.S. Underwriters, dated the Closing Date and
addressed to you, as Representatives of the several U.S. Underwriters, with
respect to the matters referred to in clauses (iii) (other than subclause (B)
thereof), (v), (vi), (viii) (other than subclause (B) thereof) and the paragraph
immediately following clause (x) of the foregoing paragraph (d) and such other
related matters as you may request.

          (h) (i)  No stop order suspending the effectiveness of the
Registration Statement shall have been issued and no proceedings for that
purpose shall have been taken or, to the knowledge of the Company, shall be
contemplated by the Commission at or prior to the Closing Date; (ii) there shall
not have been any change in the capital stock of the Company nor any material
increase in the short-term (other than in the ordinary course of business) or
long-term debt of the Company from that set forth or contemplated in the
Registration Statement or the Prospectuses (or any amendment or supplement
thereto); (iii) there shall not have been, since the respective dates as of
which information is given in the Registration Statement and the Prospectuses
(or any amendment or supplement thereto), except as may otherwise be stated in
the Registration Statement and Prospectuses (or any amendment or supplement
thereto), any material adverse change in the condition (financial or other),
business, prospects, properties, net worth or results of operations of the
Company and the Subsidiaries, taken as a whole; and (iv) all the representations
and warranties of the Company contained in this Agreement shall be true and
correct on and as of the date hereof and on and as of the Closing Date as if
made on and as of the Closing Date, and you shall have received a certificate,
dated the Closing Date and signed by the chief executive officer and the chief
financial officer of the Company (or such other officers as are acceptable to
you), to the effect set forth in this Section 10(h) and in Section 10(i) hereof.

          (i)  The Company shall not have failed at or prior to the Closing Date
to have performed or complied with any of its agreements herein contained and
required to be performed or complied with by it hereunder at or prior to the
Closing Date.

Closing Date and signed by or on behalf of the Selling Stockholder as to the

          (k)  The Selling Stockholder shall not have failed at or prior to the

by them hereunder at or prior to the Closing Date.

          (l)  The Shares shall have been listed or approved for listing subject
to notice of issuance on the New York Stock Exchange.

          (m)  The Sellers shall have furnished or caused to be furnished to you

                                      -26-

<PAGE>

          All such opinions, certificates, letters and other documents will be
in compliance with the provisions hereof only if they are reasonably
satisfactory in form and substance to you and your counsel. 

          Any certificate or document signed by any officer of the Company or by

of the several U.S. Underwriters, or to counsel for the U.S. Underwriters, shall
be deemed a representation and warranty by the Company or the Selling
Stockholder, as the case may be, to each U.S. Underwriter as to the statements
made therein. 

          The several obligations of the U.S. Underwriters to purchase
Additional Shares hereunder are subject to the satisfaction on and as of any
Option Closing Date of the conditions set forth in this Section 10, except that,
if any Option Closing Date is other than the Closing Date, the certificates,
opinions and letters referred to in paragraphs (c) through (h) and paragraphs
(j), (k) and (n) shall be dated the Option Closing Date in question and the
opinions or letters called for by paragraphs (c) through (f) shall be revised

costs or expenses.

     12.  EFFECTIVE DATE OF AGREEMENT.  This Agreement shall become effective:
(i) upon the execution and delivery hereof by the parties hereto; or (ii) if, at
the time this Agreement is executed and

                                      -27-

<PAGE>

delivered, it is necessary for the registration statement or a post-effective
amendment thereto or an Additional Registration Statement to be declared
effective before the offering of the Shares may commence, when notification of
the effectiveness of the registration statement or such post-effective amendment
or Additional Registration Statement has been released by the Commission.  Until
such time as this Agreement shall have become effective, it may be terminated by
the Company, by notifying you, or by you, as Representatives of the several U.S.
Underwriters, by notifying the Company and the Selling Stockholder. 

          If any one or more of the U.S. Underwriters shall fail or refuse to
purchase Shares which it or they are obligated to purchase hereunder on the
Closing Date, and the aggregate number of Shares which such defaulting U.S.
Underwriter or Underwriters are obligated but fail or refuse to purchase is not
more than one-tenth of the aggregate number of Shares which the U.S.
Underwriters are obligated to purchase on the Closing Date, each non-defaulting
U.S. Underwriter shall be obligated, severally, in the proportion which the
number of Firm Shares set forth opposite its name in Schedule II hereto bears to
the aggregate number of Firm Shares set forth opposite the names of all
non-defaulting U.S. Underwriters or in such other proportion as you may specify
in accordance with Section 20 of the Master Agreement Among Underwriters of
Smith Barney Inc., to purchase the Shares which such defaulting U.S. Underwriter
or Underwriters are obligated, but fail or refuse, to purchase.  If any one or
more of the U.S. Underwriters shall fail or refuse to purchase Shares which it
or they are obligated to purchase on the Closing Date and the aggregate number
of Shares with respect to which such default occurs is more than one-tenth of
the aggregate number of Shares which the U.S. Underwriters are obligated to
purchase on the Closing Date and arrangements satisfactory to you and the
Company for the purchase of such Shares by one or more non-defaulting U.S.
Underwriters or other party or parties approved by you and the Company are not
made within 36 hours after such default, this Agreement will terminate without
liability on the part of any non-defaulting U.S. Underwriter or the Company.  In
any such case which does not result in termination of this Agreement, either you
or the Company shall have the right to postpone the Closing Date, but in no
event for longer than seven days, in order that the required changes, if any, in
the Registration Statement and the Prospectus or any other documents or
arrangements may be effected.  Any action taken under this paragraph shall not
relieve any defaulting U.S. Underwriter from liability in respect of any such
default of any such Underwriter under this Agreement.  The term "U.S.
Underwriter" as used in this Agreement includes, for all purposes of this
Agreement, any party not listed in Schedule II hereto who, with your approval
and the approval of the Company, purchases Shares which a defaulting U.S.
Underwriter is obligated, but fails or refuses, to purchase.

     Any notice under this Section 12 may be given by telegram, telecopy or
telephone but shall be subsequently confirmed by letter. 

     13.  TERMINATION OF AGREEMENT.  This Agreement shall be subject to
termination in your absolute discretion, without liability on the part of any
U.S. Underwriter to the Company or the Selling Stockholder, by notice to the
Company, if prior to the Closing Date or any Option Closing Date (if different
from the Closing Date and then only as to the Additional Shares), as the case
may be, (i) trading in the Common Stock of the Company shall be suspended or
subject to any restriction or limitation not in effect on the date of this
Agreement; (ii) trading in securities generally on the New York Stock Exchange,
the American Stock Exchange or the Nasdaq National Market shall have been
suspended or materially limited; (iii) a general moratorium on commercial
banking activities in New York shall have been declared by either federal or
state authorities; or (iv) there shall have occurred any outbreak or escalation
of hostilities or other international or domestic calamity, crisis or change in
political, financial or economic conditions, the effect of which on the
financial markets of the United States is such as to make it, in your

                                      -28-

judgment, impracticable or inadvisable to commence or continue the offering of
the Shares at the offering price to the public set forth on the cover page of
the U.S. Prospectus or to enforce contracts for the resale of the Shares by the
U.S. Underwriters.

     Notice of such termination may be given by telegram, telecopy or telephone
and shall be subsequently confirmed by letter. 

     14.  INFORMATION FURNISHED BY THE U.S. UNDERWRITERS.  The statements set
forth in the last paragraph on the cover page, the stabilization legend on the
inside front cover page, and the statements in the first and fourth paragraphs

U.S. Underwriters through you as such information is referred to in Sections
7(b) and 9 hereof.

U.S. Underwriters, the Company, its directors and officers, the other
controlling persons referred to in Section 9 hereof and the Selling Stockholders
and their respective successors and assigns, to the extent provided herein, and
no other person shall acquire or have any right under or by virtue of this
Agreement.  Neither the term "successor" nor the term "successors and assigns"
as used in this Agreement shall include a purchaser from any U.S. Underwriter of
any of the Shares in his status as such purchaser. 

     16.  APPLICABLE LAW; COUNTERPARTS.  This Agreement shall be governed by and
construed in accordance with the laws of the State of New York applicable to
contracts made and to be performed within the State of New York.

     This Agreement may be signed in various counterparts which together
constitute one and the same instrument.  If signed in counterparts, this
Agreement shall not become effective unless at least one counterpart hereof

c/o SMITH BARNEY INC.
    388 Greenwich Street

Dear Sirs:

         Health Systems International, Inc., a Delaware corporation (the
"Company"), proposes to issue and sell an aggregate of 638,875 shares of its
Class A Common Stock, par value $0.001 per share (the "Common Stock"), to the
several Underwriters named in Schedule II hereto (the "Managers"), and The
California Wellness Foundation as the selling stockholder (the "Selling
Stockholder") proposes to sell to the several Managers an aggregate of 1,027,366
shares of the Company's Class B Common Stock, par value $0.001 per share, which
upon sale to the several Managers is converted into Common Stock (the "Class B
Common Stock").  The 638,875 shares of Common Stock to be issued and sold to
the Managers by the Company and the 1,027,366 shares of Class B Common Stock to
be sold to the Managers by the Selling Stockholder are hereinafter referred to
as the "Firm Shares."  In addition, solely for the purpose of covering over-
allotments, the Selling Stockholder proposes to sell to the Managers, upon the
terms and conditions set forth in Section 2 hereof, up to an additional
249,936 shares of Class B Common Stock (the "Additional Shares").  The Firm
Shares and the Additional Shares are hereinafter collectively referred to as the
"Shares."  The Company and the Selling Stockholder are hereinafter sometimes
referred to as the "Sellers."

         It is understood that the Company and the Selling Stockholder are
concurrently entering into a U.S. Underwriting Agreement, dated the date hereof
(the "U.S. Underwriting Agreement"), providing for



<PAGE>

the sale of 6,664,964 shares of the Common Stock (the "Firm U.S. Shares"), of
which 2,555,499 shares will be sold by the Company and 4,109,464 will be sold
by the Selling Stockholder (plus an option granted by the Selling Stockholder to
purchase up to an additional 999,744] shares of Common Stock (the "Additional
U.S. Shares") solely for the purpose of covering over-allotments) through
arrangements with certain underwriters in the United States and Canada (the
"U.S. Underwriters"), for whom Smith Barney Inc., Dillon, Read & Co. Inc., Dean
Witter Reynolds Inc., Robertson, Stephens & Company LLC, Salomon Brothers Inc
and Volpe, Welty & Company are acting as representatives (the
"Representatives").  All shares of Common Stock proposed to be offered to the
U.S. Underwriters pursuant to the U.S. Underwriting Agreement, including the
Firm U.S. Shares and the Additional U.S. Shares, are herein called the "U.S.
Shares"; the U.S. Shares and the Shares, collectively, are herein called the
"Underwritten Shares."

         The Company and the Selling Stockholder also understand that the Lead
Managers and the Representatives have entered into an agreement (the "Agreement
Between U.S. Underwriters and Managers") contemplating the coordination of
certain transactions between the Managers and the U.S. Underwriters and that,
pursuant thereto and subject to the conditions set forth therein, the Managers
may purchase from the U.S. Underwriters a portion of the U.S. Shares or sell to
the U.S. Underwriters a portion of the Shares.  The Company and the Selling
Stockholder understand that any such purchases and sales between the Managers
and the U.S. Underwriters shall be governed by the Agreement Between U.S.
Underwriters and Managers and shall not be governed by the terms of this
Agreement or the U.S. Underwriting Agreement.

         The Sellers wish to confirm as follows their agreement with you (the
"Lead Managers") and the other several Managers on whose behalf you are acting,
in connection with the several purchases of the Shares by the Managers.

    1.   REGISTRATION STATEMENT AND PROSPECTUS.  The Company has prepared and
filed with the Securities and Exchange Commission (the "Commission") in
accordance with the provisions of the Securities Act of 1933, as amended, and
the rules and regulations of the Commission thereunder (collectively, the
"Act"), a registration statement on Form S-3 under the Act (the "registration
statement"), including prospectuses subject to completion, relating to the
Underwritten Shares.  The term "Registration Statement" as used in this
Agreement means the registration statement (including all financial schedules
and exhibits), as amended at the time it becomes effective, and as thereafter
amended by post-effective amendment.  If an additional registration statement is
prepared and filed with the Commission in accordance with Rule 462(b) under the
Act (an "Additional Registration Statement"), the term "Registration Statement"
as used in this Agreement includes the Additional Registration Statement.  The
term "Prospectuses" as used in this Agreement means the prospectuses in the
forms included in the Registration Statement, or, if the prospectuses included
in the Registration Statement omit information in reliance on Rule 430A under
the Act and such information is included in prospectuses filed with the
Commission pursuant to Rule 424(b) under the Act, the term "Prospectuses" as
used in this Agreement means the prospectuses in the forms included in the
Registration Statement as supplemented by the addition of the Rule 430A
information contained in the prospectuses filed with the Commission pursuant to
Rule 424(b).  The term "Prepricing Prospectuses" as used in this Agreement means
the prospectuses subject to completion in the forms included in the Registration
Statement at the time of the initial filing of the Registration Statement with
the Commission, and as such prospectuses shall have been amended from time to
time prior to the date of the Prospectuses.  Any reference in this Agreement to
the registration statement, the Registration Statement, any Prepricing
Prospectus or the Prospectus shall be deemed to refer to and include the
documents incorporated by reference therein pursuant to Item 12 of Form S-3
under the Act, as of the date of the registration statement, the Registration
Statement, such Prepricing Prospectus or the Prospectus, as the case may be, and
any reference to any amendment or

                                       -2-

<PAGE>

supplement to the registration statement, the Registration Statement, any
Prepricing Prospectus or the Prospectus shall be deemed to refer to and include
any documents filed after such date under the Securities Exchange Act of 1934,
as amended, and the rules and regulations of the Commission thereunder
(collectively, the "Exchange Act") which, upon filing, are incorporated by
reference therein, as required by paragraph (b) of Item 12 of Form S-3.  As used
herein, the term "Incorporated Documents" means the documents which at the time
are incorporated by reference in the registration statement, the Registration
Statement, any Prepricing Prospectus, the Prospectus, or any amendment or
supplement thereto.

         It is understood that two forms of Prepricing Prospectus and two forms
of Prospectus are to be used in connection with the offering and sale of the
Underwritten Shares:  a Prepricing Prospectus and a Prospectus relating to the
Shares that are to be offered and sold in the United States (as defined herein)
or Canada (as defined herein) to U.S. or Canadian Persons (the "U.S. Prepricing
Prospectus" and the "U.S. Prospectus," respectively), and a Prepricing
Prospectus and a Prospectus relating to the International Shares which are to be
offered and sold outside the United States or Canada to persons other than U.S.
or Canadian Persons (the "International Prepricing Prospectus" and the
"International Prospectus," respectively).  The U.S. Prospectus and the
International Prospectus are herein collectively called the "Prospectuses," and
the U.S. Prepricing Prospectus and the International Prepricing Prospectus are
herein called the "Prepricing Prospectuses."  For purposes of this Agreement:
"U.S. or Canadian Person" means any resident or national of the United States or
Canada, any corporation, partnership or other entity created or organized in or
under the laws of the United States or Canada or any estate or trust the income
of which is subject to United States or Canadian income taxation regardless of
the  source of its income (other than the foreign branch of any U.S. or Canadian
Person), and includes any United States or Canadian branch of a person other
than a U.S. or Canadian Person; "United States" means the United States of
America (including the states thereof and the District of Columbia) and its
territories, its possessions and other areas subject to its jurisdiction; and
"Canada" means Canada and its territories, its possessions and other areas
subject to its jurisdiction.

    2.   AGREEMENTS TO SELL AND PURCHASE.   Upon the basis of the
representations, warranties and agreements contained herein and subject to all
the terms and conditions set forth herein and to such adjustments as you may
determine to avoid fractional shares, the Company hereby agrees to issue and
sell to each Manager and each Manager agrees, severally and not jointly, to
purchase from the Company, at a purchase price of $      per share (the
"purchase price per share"), the number of Firm Shares that bears the same
proportion to the aggregate number of Firm Shares to be issued and sold by the
Company as the number of Firm Shares set forth opposite the name of such Manager
in Schedule II hereto (or such number of Firm Shares increased as set forth in
Section 12 hereof) bears to the aggregate number of Firm Shares to be sold by
the Company and the Selling Stockholder.

    Upon the basis of the representations, warranties and agreements contained
herein and subject to all the terms and conditions set forth herein and to such
adjustments as you may determine to avoid fractional shares, the Selling
Stockholder agrees to sell to each Manager and each Manager agrees, severally
and not jointly, to purchase from the Selling Stockholder, at the purchase price
per share, the number of Firm Shares that bears the same proportion to the
number of Firm Shares set forth opposite the name of the Selling Stockholder in
Schedule I hereto as the number of Firm Shares set forth opposite the name of
such Manager in Schedule II hereto (or such number of Firm Shares increased as
set forth in Section 12 hereof) bears to the aggregate number of Firm Shares to
be sold by the Company and the Selling Stockholder.

    Upon the basis of the representations, warranties and agreements contained
herein and subject to all the terms and conditions set forth herein, the Selling
Stockholder also agrees to sell to the Managers, and the

                                       -3-

<PAGE>

Managers shall have the right to purchase from the Selling Stockholder, at the
purchase price per share, pursuant to an option (the "over-allotment option")
which may be exercised prior to 5:00 p.m., New York City time, on the 30th day
after the date of the International Prospectus (or, if such 30th day shall be a
Saturday or Sunday or a holiday, on the next business day thereafter when the
New York Stock Exchange is open for trading), up to an aggregate of 300,000
Additional Shares from the Selling Stockholder.  Upon any exercise of the
over-allotment option, each Manager, severally and not jointly, agrees to
purchase from  the Selling Stockholder the number of Additional Shares (subject
to such adjustments as you may determine in order to avoid fractional shares)
that bears the same proportion to the number of Additional Shares to be sold by
the Selling Stockholder as the number of Firm Shares set forth opposite the name
of such Manager in Schedule II hereto (or such number of Firm Shares increased
as set forth in Section 12 hereof) bears to the aggregate number of Firm Shares
to be sold by the Selling Stockholder.

         Each Manager represents, warrants, covenants and agrees that, except
as contemplated under Section 2 of the Agreement Between U.S. Underwriters and
Managers dated the date hereof, (i) it is not purchasing any Shares for the
account of a U.S. or Canadian Person, and (ii) it has not offered or sold, and
will not offer, sell, resell or deliver, directly or indirectly, any Shares or
distribute any International Prospectus inside the United States or Canada or to
any U.S. or Canadian Person.


    3.   TERMS OF PUBLIC OFFERING.  The Sellers have been advised by you that
the Managers propose to make a public offering of their respective portions of
the Shares as soon after the Registration Statement and this Agreement have
become effective as in your judgment is advisable and initially to offer the
Shares upon the terms set forth in the International Prospectus.

    4.   DELIVERY OF THE SHARES AND PAYMENT THEREFOR.  Delivery to the Managers

    5.   AGREEMENTS OF THE COMPANY.  The Company agrees with the several
Managers as follows:

         (a)  If, at the time this Agreement is executed and delivered, it is
necessary for the Registration Statement or a post-effective amendment thereto
or any Additional Registration Statement to be declared effective before the
offering of the Shares may commence, the Company will endeavor to cause the
Registration Statement or such post-effective amendment to become effective as
soon as possible and will advise you promptly and, if requested by you, will
confirm such advice in writing, when the Registration Statement or such
post-effective amendment or Additional Registration Statement has become
effective.

         (b)  The Company will advise you promptly and, if requested by you,
will confirm such advice in writing: (i) of any request by the Commission for
amendment of or a supplement to the Registration Statement, any Prepricing
Prospectuses or the Prospectuses or for additional information; (ii) of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement or of the suspension of qualification of the Shares for
offering or sale in any jurisdiction or the initiation of any proceeding for
such purpose; and (iii) within the period of time referred to in paragraph (f)
below, of any change in the Company's condition (financial or other), business,
prospects, properties, net worth or results of operations, or of the happening
of any event, including the filing of any information, documents or reports
pursuant to the Exchange Act, that makes any statement made in the Registration
Statement or the Prospectuses (as then amended or supplemented) untrue in any
material respect or which requires the making of any additions to or changes in
the Registration Statement or the Prospectuses (as then amended or supplemented)
in order to state a material fact required by the Act or the regulations
thereunder to be stated therein or necessary in order to make the statements
therein not misleading, or of the necessity to amend or supplement the
Prospectuses (as then amended or supplemented) to comply with the Act or any
other law.  If at any time the Commission shall issue any stop order suspending
the effectiveness of the Registration Statement, the Company will make every
reasonable effort to obtain the withdrawal of such order at the earliest
possible time.

         (c)  The Company will furnish to you, without charge (i) seven signed
copies of the Registration Statement as originally filed with the Commission and
of each amendment thereto, including financial statements and all exhibits to
the Registration Statement, and (ii) such number of conformed copies of the
Registration Statement as originally filed and of each amendment thereto, but
without exhibits, and the Incorporated Documents thereto as you may request.

         (d)  The Company will not (i) file any amendment to the Registration
Statement or make any amendment or supplement to the Prospectuses or, prior to
the end of the period of time referred to in the first sentence in subsection
(f) below, file any document which, upon filing becomes an Incorporated
Document, of which you shall not previously have been advised or with respect to
which you shall not previously have been consulted or (ii) so long as, in the
opinion of counsel for the Managers a prospectus is required to be delivered in
connection with sales by any Manager or dealer, file any information, documents
or reports pursuant to the Exchange Act, without delivering a copy of such
information, documents or reports to you, as Lead Managers for the Managers,
prior to or concurrently with such filing.

         (e)  Prior to the execution and delivery of this Agreement, the
Company has delivered or will deliver to you, without charge, in such quantities
as you have requested or may hereafter request, copies of

                                       -5-

<PAGE>

each International Prepricing Prospectus.  The Company consents to the use, in
accordance with the provisions of the Act and with the securities or Blue Sky
laws of the jurisdictions in which the Shares are offered by the several
Managers and by dealers, prior to the date of the International Prospectus, of
each International Prepricing Prospectus so furnished by the Company.

         (f)  As soon after the execution and delivery of this Agreement as
possible and thereafter from time to time for such period as in the written
opinion of counsel for the Managers an International Prospectus is required by
the Act to be delivered in connection with sales by any Manager or dealer, the
Company will expeditiously deliver to each Manager and each dealer, without
charge, as many copies of the International Prospectus (and of any amendment or
supplement thereto) as you may reasonably request.  The Company consents to the
use of the International Prospectus (and of any amendment or supplement thereto)
in accordance with the provisions of the Act and with the securities or Blue Sky
laws of the jurisdictions in which the Shares are offered by the several
Managers and by all dealers to whom Shares may be sold, both in connection with
the offering and sale of the Shares and for such period of time thereafter as
the International Prospectus is required by the Act to be delivered in
connection with sales by any Manager or dealer.  If during such period of time
any event shall occur that in the judgment of the Company or in the opinion of
counsel for the Managers is required to be set forth in the International
Prospectus (as then amended or supplemented) or should be set forth therein in
order to make the statements therein, in the light of the circumstances under
which they were made, not misleading, or if it is necessary to supplement or
amend the International Prospectus (or to file under the Exchange Act any
document which, upon filing, becomes an Incorporated Document) to comply with
the Act, the Exchange Act or any other law, the Company will forthwith prepare
and, subject to the provisions of paragraph (d) above, file with the Commission
an appropriate supplement or amendment thereto or such document, and will
expeditiously furnish to the Managers and dealers a reasonable number of copies
thereof.  In the event that the Company and you, as Lead Managers for the
several Managers, agree that either the Prospectuses should be amended or
supplemented, or that a document should be filed under the Exchange Act which
upon filing becomes an Incorporated Document, the Company, if requested by you,
will promptly issue a press release announcing or disclosing the matters to be
covered by the proposed amendment or supplement or such document.

         (g)  The Company will cooperate with you and with counsel for the
Managers in connection with the registration or qualification of the Shares for
offering and sale by the several Managers and by dealers under the securities or
Blue Sky laws of such jurisdictions as you may designate and will file such
consents to service of process or other documents necessary or appropriate in
order to effect such registration or qualification; provided that in no event
shall the Company be obligated to qualify to do business in any jurisdiction
where it is not now so qualified or to take any action that would subject it to
service of process in suits, other than those arising out of the offering or
sale of the Shares, in any jurisdiction where it is not now so subject.

         (h)  The Company will make generally available to its security holders
a consolidated earnings statement, which need not be audited, covering a
twelve-month period commencing after the effective date of the Registration
Statement and ending not later than 15 months thereafter, as soon as practicable
after the end of such period, which consolidated earnings statement shall
satisfy the provisions of Section 11(a) of the Act.

         (i)  During the period of five years hereafter, the Company will
furnish to you (i) as soon as available, a copy of each report of the Company
mailed to stockholders or filed with the Commission or the

                                       -6-

<PAGE>

New York Stock Exchange, and (ii) from time to time such other information
concerning the Company as you may request.

         (j)  If this Agreement shall terminate or shall be terminated after
execution pursuant to any provisions hereof (otherwise than pursuant to the
second paragraph of Section 12 hereof or by notice given by you terminating this
Agreement pursuant to Section 12 or Section 13 hereof) or if this Agreement
shall be terminated by the Managers because of any failure or refusal on the
part of the Company or the Selling Stockholder to comply with the terms or
fulfill any of the conditions of this Agreement, the Company agrees to reimburse
the Lead Managers for all out-of-pocket expenses (including fees and expenses of
counsel for the Managers) incurred by you in connection herewith.

         (k)  The Company will apply the net proceeds from the sale of the
Shares to be sold by it hereunder substantially in accordance with the
description set forth in the Prospectuses under the caption "Use of Proceeds."

         (l)  If Rule 430A of the Act is employed or if Rule 424(b) is
otherwise applicable, the Company will timely file the Prospectuses pursuant to
Rule 424(b) under the Act and will advise you of the time and manner of such
filing.

         (m)  For a period of 90 days after the date hereof (the "Lock up
Period"), the Company will not, without the prior written consent of Smith
Barney Inc., offer, sell, contract to sell or otherwise dispose of any Common
Stock or Class B Common Stock (or any securities convertible into or exercisable
or exchangeable for Common Stock or Class B Common Stock) except (i) for sales
to the Managers pursuant to this Agreement and the U.S. Underwriters pursuant to
the U.S. Underwriting Agreement, (ii) the issuance of Class A Common Stock by
the Company pursuant to acquisitions, mergers or other similar transactions, and
(iii) the issuance of shares by the Company pursuant to employee and non-
employee director stock options and the issuance or granting of shares or
options by the Company pursuant to employee benefit, stock option, employee
stock purchase and compensation plans of the Company.

         (n)  The Company has furnished or will furnish to you "lock-up"
letters, in form and substance satisfactory to you, signed by each of its
current executive officers and directors and each of its stockholders designated
by you.

         (o)  Except as stated in this Agreement and in the U.S. Underwriting
Agreement and in the Prepricing Prospectuses and the Prospectuses, the Company
has not taken, nor will it take, directly or indirectly, any action designed to
or that might reasonably be expected to cause or result in stabilization or
manipulation of the price of the Common Stock to facilitate the sale or resale
of the Shares.

         (p)  The Company will use its best efforts to have the Shares listed,
subject to notice of issuance, on the New York Stock Exchange prior to or
concurrently with the effectiveness of the registration statement.

         (q)  The Company will use its best efforts to satisfy on or before the
Closing Date all conditions to the Managers' obligations to purchase the Shares.

    6.   AGREEMENTS OF THE SELLING STOCKHOLDER.  The Selling Stockholder agrees
with the several Managers as follows:

Agreement.

          (d)  The Selling Stockholder has executed or will execute a "lock-up"
letter as provided in Section 5(n) above and will not offer, sell, contract to
sell or otherwise dispose of any Common Stock or Class B Common Stock or any
securities convertible into, or exercisable for Common Stock or Class B Common
Stock, except for the sale of Shares to the Managers pursuant to this Agreement
and the U.S. Underwriters pursuant to the U.S. Underwriting Agreement, prior to
the expiration of 90 days after the date of the Prospectus, without the prior
written consent of Smith Barney Inc.

         (e)  Except as stated in this Agreement and the U.S. Underwriting
Agreement and in the Prepricing Prospectuses and the Prospectuses, the Selling
Stockholder has not taken, nor will it take, directly or indirectly, any action
designed to or that might reasonably be expected to cause or result in
stabilization or manipulation of the price of the Common Stock to facilitate the
sale or resale of the Shares.

    7.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company represents
and warrants to each Manager that:

         (a)  Each International Prepricing Prospectus included as part of the
registration statement as originally filed or as part of any amendment or
supplement thereto, or filed pursuant to Rule 424 under the Act, complied when
so filed in all material respects with the provisions of the Act; except that
this representation and warranty does not apply to statements in or omissions
from such International Prepricing Prospectus (or any amendment or supplement
thereto) made in reliance upon and in conformity with information relating to
and furnished by any Manager or U.S. Underwriter to the Company in writing by a
Manager through the Lead Managers through you or by a U.S. Underwriter through
the Representatives expressly for use therein.  The Commission has not issued

         (b)  The Company meets the requirements for the use of Form S-3

all material respects with the provisions of the Act at the respective

to be 

                                       -8-

stated therein or necessary in order to make the statements therein, in light 
of the circumstances under which they were made, not misleading; except that 
this representation and warranty does not apply to statements in or omissions

in conformity with information relating to any Manager or U.S. Underwriter 
and furnished to the Company in writing by a Manager through the Lead 
Managers or by a U.S. Underwriter through the Representatives expressly for 
use therein.

         (c)  The Incorporated Documents heretofore filed were filed in a
timely manner with the Commission, and when they were filed (or, if any
amendment with respect to any such document was filed, when such amendment was
filed) conformed in all material respects to the requirements of the Exchange
Act and 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

filed in a timely manner and conform in all material respects to the
requirements of the Exchange Act and will not 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 not misleading.

         (d)  All the outstanding shares of Common Stock of the Company and
(except as expressly disclosed in the Registration Statement, the Prepricing

issued, are fully paid and nonassessable and are free of any preemptive or
similar rights; the Shares to be issued and sold by the Company have been duly

therefor in accordance with the terms hereof, will be validly issued, fully paid
and nonassessable and free of any preemptive or similar rights; and the capital
stock of the Company conforms in all material respects to the description
thereof in the Registration Statement and the Prospectuses.

         (e)  The Company is a corporation duly organized and validly existing
in good standing under the laws of the State of Delaware with full corporate
power and authority to own, lease and operate its properties and to conduct its
business as described in the Registration Statement and the Prospectuses, and is
duly registered and qualified to conduct its business and is in good standing in
each jurisdiction where the nature of its properties or the conduct of its
business requires such registration or qualification, except where the failure
so to register or qualify does not have a material adverse effect on the
condition (financial or other), business, prospects, properties, net worth or
results of operations of the Company and the Subsidiaries (as hereinafter
defined) taken as a whole (a "Material Adverse Effect").

         (f)  All the Company's subsidiaries (collectively, the "Subsidiaries")
are listed in an exhibit to the Company's Annual Report on Form 10-K which is
incorporated by reference into the Registration Statement.  Each Subsidiary is a
corporation duly organized, validly existing and in good standing in the

so described in the Registration Statement and the Prospectus, and is duly
registered and qualified to conduct its business and is in good standing in each
jurisdiction or place where the nature of its properties or the conduct of its
business requires such registration or qualification, except where the failure

or results of operations of such Subsidiary; all the outstanding shares of
capital stock of each of the Subsidiaries have been duly authorized and validly
issued, are fully paid and nonassessable, and are owned by the Company directly,

<PAGE>

one of the other Subsidiaries, free and clear of any lien, adverse claim,
security interest, equity or other encumbrance.

         (g)  There are no legal or governmental actions, suits, claims,
proceedings or investigations pending or, to the knowledge of the Company,
threatened, against the Company or any of the Subsidiaries or against or
involving any of its officers, directors or employees in connection with the
business or affairs of the Company, including, without limitation, any claims
for indemnification arising under any agreement to which the Company is a party,
or to which the Company or any of the Subsidiaries or any of their respective
properties, is subject which could have a Material Adverse Effect (including,
without limitation, any proceeding to revoke or deny renewal of any Permits (as
defined herein) of the Company or any of the Subsidiaries) that are required to
be described in the Registration Statement or the Prospectuses but are not
described as required, and there are no agreements, contracts, indentures,
leases or other instruments relating to the Company that are required to be
described in the Registration Statement or the Prospectuses or to be filed as an
exhibit to the Registration Statement or any Incorporated Document that are not
described or filed as required by the Act or the Exchange Act.  Any descriptions
of the terms of any such contracts or documents contained in the Registration
Statement or the Prospectuses are correct in all material respects.  The Company
is not subject to or in default with respect to any writ, order, judgment,
injunction or decree which could have a Material Adverse Effect.

         (h)  Neither the Company nor any of the Subsidiaries is in (i)
violation of its certificate or articles of incorporation or by-laws, or other
organizational documents, (ii) in violation of any law, ordinance,
administrative or governmental rule or regulation applicable to the Company or
any of the Subsidiaries or of any decree of any court or governmental agency or
body having jurisdiction over the Company or any of the Subsidiaries (except
where any such violation or violations in the aggregate would not have a
Material Adverse Effect), or (iii) in default in any material respect in the
performance of any obligation, agreement or condition contained in any bond,
debenture, note or any other evidence of indebtedness or in any material
agreement, indenture, lease or other instrument to which the Company or any of
the Subsidiaries is a party or by which any of them or any of their respective
properties may be bound, and no condition or state of facts exists, which with
the passage of time or the giving of notice or both, would constitute such a
default (except where any such default or defaults in the aggregate would not
have a Material Adverse Effect).

         (i)  Neither the issuance, offer, sale or delivery of the Shares, the
execution, delivery or performance of this Agreement or the U.S. Underwriting
Agreement by the Company nor the consummation by the Company of the transactions
contemplated hereby and thereby (i) requires any consent, approval,
authorization or other order of or registration or filing with, any court,
regulatory body, administrative agency or other governmental body, agency or
official (except such as may be required for the registration of the Shares
under the Act and compliance with the securities or Blue Sky laws of various
jurisdictions, all of which have been or will be effected in accordance with
this Agreement) or conflicts or will conflict with or constitutes or will
constitute a breach of, or a default under, the certificate or articles of
incorporation or bylaws, or other organizational documents, of the Company or
any of the Subsidiaries, (ii) conflicts or will conflict with or constitutes or
will constitute a breach of, or a default under, any agreement, indenture, lease
or other instrument to which the Company or any of the Subsidiaries is a party
or by which any of them or any of their respective properties may be bound, or
violates or will violate any statute, law, regulation or filing or judgment,
injunction, order or decree applicable to the Company or any of the Subsidiaries
or any of their respective properties, except any such conflict, breach, default
or violation which could not have a Material Adverse Effect, or (iii) will
result in the creation or imposition of any material lien, charge or encumbrance
upon any property or assets of the Company or any of the Subsidiaries pursuant
to the terms of any agreement

                                      -10-

<PAGE>

or instrument to which any of them is a party or by which any of them may be
bound or to which any of the property or assets of any of them is subject other
than security interests granted pursuant to the Credit Agreement, except for any
such lien, charge or encumbrance that would not have a Material Adverse Effect.

         (j)  The accountants, Deloitte & Touche LLP, who have certified or
shall certify the financial statements included or incorporated by reference
into the Registration Statement or the Prospectuses (or any amendment or
supplement thereto) are independent public accountants as required by the Act.

         (k)  The financial statements, together with related schedules and
notes included or incorporated by reference into the Registration Statement and
the Prospectuses (and any amendment or supplement thereto), present fairly the
consolidated financial position, results of operations, cash flows and changes
in stockholders' equity of the Company and the Subsidiaries on the basis stated
in the Registration Statement at the respective dates or for the respective
periods to which they apply; such statements and related schedules and notes
have been prepared in accordance with generally accepted accounting principles
consistently applied throughout the periods involved, except as disclosed
therein; and the other financial and statistical information and data included
or incorporated by reference into the Registration Statement and the
Prospectuses (and any amendment or supplement thereto) are accurately presented
and prepared on a basis consistent with the books and records of the Company and
its Subsidiaries.  The pro forma financial statements and other pro forma
financial information (including the notes thereto) included in or incorporated
by reference into the Registration Statement and the Prospectuses present fairly
the information shown therein, have been prepared in accordance with applicable
requirements of the Act (including Article 11 of Regulation S-X), have been
prepared in accordance with the Commission's rules and guidelines with respect
to pro forma financial statements and have been properly computed on the basis
described therein.  The assumptions used in preparation of the pro forma
financial statements and other pro forma financial information included in or
incorporated by reference into the Registration Statement and the Prospectuses
are reasonable, and the adjustments used therein are reasonably appropriate to
give effect to the transactions or circumstances referred to therein.

         (l)  The execution and delivery of, and the performance by the Company
of its obligations under, each of this Agreement and the U.S. Underwriting
Agreement have been duly and validly authorized by the Company, and each of this
Agreement and the U.S. Underwriting Agreement has been duly executed and
delivered by the Company and constitutes the valid and legally binding agreement
of the Company, enforceable against the Company in accordance with its terms,
except (i) the enforceability hereof or thereof may be limited by bankruptcy,
insolvency, reorganization, moratorium or other similar laws now or hereafter in
effect relating to creditors' rights generally, (ii) the remedy of specific
performance and other forms of equitable relief may be subject to certain
equitable defenses and to the discretion of the court before which the
proceedings may be brought and (iii) rights to indemnity and contribution
hereunder or thereunder may be limited by federal or state securities laws or
the public policy underlying such laws.

         (m)  Except as disclosed in the Registration Statement and the
Prospectuses (or any amendment or supplement thereto), subsequent to the
respective dates as of which such information is given in the Registration
Statement and the Prospectuses (or any amendment or supplement thereto), neither
the Company nor any of the Subsidiaries has incurred any liability or
obligation, direct or contingent, or entered into any transaction, not in the
ordinary course of business, that could result in a Material Adverse Effect, and
there has not been any change in the capital stock of the Company (other than
the issuance of Common Stock upon exercise of options under the Company's stock
option plans described in the Prospectus), or material

                                      -11-

<PAGE>

increase in the short-term debt or long-term debt, of the Company or any of the
Subsidiaries, or any development having or which may reasonably be expected to
have, a Material Adverse Effect.

         (n)  Each of the Company and the Subsidiaries has good and marketable
title to all property (real and personal) described in the Prospectuses as being
owned by it, free and clear of all liens, claims, security interests or other
encumbrances except such as are described in the Registration Statement and the
Prospectuses or in a document filed as an exhibit to the Registration Statement
and all the property described in the Prospectuses as being held under lease by
each of the Company and the Subsidiaries is held by it under valid, subsisting
and enforceable leases with only such exceptions as in the aggregate are not
materially burdensome and do not interfere in any material respect with the
conduct of the business of the Company and the Subsidiaries, taken as a whole.

         (o)  The Company has not distributed and, prior to the later to occur
of (i) the Closing Date or the Option Closing Date, if any, and (ii) completion
of the distribution of the Shares, will not distribute any offering material in
connection with the offering and sale of the Shares other than the Registration
Statement, the Prepricing Prospectuses, the Prospectuses or other materials, if
any, permitted by the Act.

         (p)  The Company and each of the Subsidiaries has such permits,
licenses, franchises and authorizations of governmental or regulatory
authorities ("Permits") as are necessary to own its respective properties and to
conduct its business in the manner described in the Prospectuses, including,
without limitation, such Permits as are required (x) under such federal and
state health care laws as are applicable to the Company or any of the
Subsidiaries or any of their respective businesses, (y) with respect to those
facilities that are owned, or leased or managed by the Company or any Subsidiary
that participate in Medicare and/or Medicaid, to receive reimbursement
thereunder, and (z) under such insurance laws and regulations which are
applicable to the Company or any of the Subsidiaries, except where the failure
to have any such Permit would not have a Material Adverse Effect and subject to
such qualifications as may be set forth in the Prospectuses; the Company and
each of the Subsidiaries has fulfilled and performed all its material
obligations with respect to such Permits and no event has occurred that allows,
or after notice or lapse of time would allow, revocation or termination thereof
or results in any other material impairment of the rights of the holder of any
such Permit, subject in each case to such qualification as may be set forth in
the Prospectuses; and, except as described in the Prospectuses, none of such
Permits contains any restriction that is materially burdensome to the Company or
any of the Subsidiaries.

         (q)  The Company maintains a system of internal accounting controls
sufficient to provide reasonable assurances that (i) transactions are executed
in accordance with management's general or specific authorization; (ii)
transactions are recorded as necessary to permit preparation of financial
statements in conformity with generally accepted accounting principles and to
maintain accountability for assets; (iii) access to assets is permitted only in
accordance with management's general or specific authorization; and (iv) the
recorded accountability for assets is compared with existing assets at
reasonable intervals and appropriate action is taken with respect to any
differences.

         (r)  To the Company's knowledge, neither the Company nor any of its
Subsidiaries nor any employee or agent of the Company or any Subsidiary has made
any payment of funds of the Company or any Subsidiary or received or retained
any funds in violation of any law, rule or regulation, which payment, receipt or
retention of funds is of a character required to be disclosed in the
Prospectuses.

                                      -12-

<PAGE>

         (s)  The Company and each of the Subsidiaries have filed all material
tax returns required to be filed, which returns are true and correct in all
material respects, and neither the Company nor any Subsidiary is in material
default in the payment of any taxes which were payable pursuant to said returns
or any assessments with respect thereto.

         (t)  Except as described in the Prospectuses, no holder of any
security of the Company has any right to require registration of shares of
Common Stock or any other security of the Company because of the filing of the
registration statement, the Registration Statement or consummation of the
transactions contemplated by this Agreement or the U.S. Underwriting Agreement,
or otherwise.  No such rights with respect to shares of Common Stock not listed
in Schedule I or Schedule II hereto were exercised nor will be exercised in
connection with the sale of the Shares and for a period of 90 days after the
date hereof.  Except as described in or contemplated by the Prospectuses, there
are no outstanding options, warrants or other rights calling for the issuance
of, and there are no commitments, plans or arrangements to issue, any shares of
Common Stock of the Company or any security convertible into or exchangeable or
exercisable for Common Stock of the Company, other than the issuance of Common
Stock upon exercise of options under the Company's stock option plans described
in the Prospectus.

         (u)  The property, assets and operations of each of the Company and
the Subsidiaries comply in all material respects with all applicable federal,
state or local laws, rules, orders, decrees, judgments, injunctions, licenses,
permits or regulations relating to environmental matters (the "Environmental
Laws"), except to the extent that failure to comply with such Environmental Laws
would not have a Material Adverse Effect.  To the best of the Company's
knowledge, none of the Company's nor any of the Subsidiaries' property, assets
or operations is the subject of any federal, state or local investigation
evaluating whether any remedial action is needed to respond to a release into
the environment of any substance regulated by, or form the basis of liability
under, any Environmental Laws (a "Hazardous Material") or is in contravention of
any federal, state, local or foreign law, order or regulation that would have a
Material Adverse Effect.  Neither the Company nor any of the Subsidiaries has
received any notice or claim, nor are there pending threatened or reasonably
anticipated lawsuits against it with respect to violations of an Environmental
Law or in connection with the release or threatened release of any Hazardous
Material into the environment.  To the best of the Company's knowledge, neither
the Company nor any of the Subsidiaries has any material contingent liability in
connection with any release or threatened release of Hazardous Material into the
environment.

         (v)  The Company and the Subsidiaries maintain insurance of the types
and in amounts generally deemed adequate for its business and consistent with
insurance coverage maintained by similar companies and businesses, all of which
insurance is in full force and effect, except where the failure to maintain such
insurance could not have a Material Adverse Effect.

         (w)  The Company and the Subsidiaries own or possess all patents,
trademarks, trademark registration, service marks, service mark registrations,
trade names, copyrights, licenses, inventions, trade secrets and rights
described in the Prospectuses as being owned by them or any of them or necessary
for the conduct of their respective businesses except where the lack of such
ownership or possession would not have a Material Adverse Effect, and the
Company is not aware of any claim to the contrary or any challenge by any other
person to the rights of the Company or any of the Subsidiaries with respect to
the foregoing.

         (x)  The Company is not and, upon sale of the Shares to be issued and
sold in accordance herewith and upon application of the net proceeds to the
Company from such sale as described in the

                                      -13-

<PAGE>

Prospectuses under the caption "Use of Proceeds," will not be an "investment
company" or a person "controlled" by an "investment company" within the meaning
of the Investment Company Act of 1940, as amended.

         (y)  Neither the Company nor its Subsidiaries does business with the
government of Cuba or with any person or affiliate located in Cuba.

         (z)  The Common Stock has been registered under the Exchange Act in
accordance with the rules and regulations thereunder.

         (aa) The Shares have been approved for listing, subject to notice of
issuance, on the NYSE.

    8.   REPRESENTATIONS AND WARRANTIES OF THE SELLING STOCKHOLDER.  The
Selling Stockholder represents and warrants to each Manager that:

         (a)  The Selling Stockholder now has, and on the Closing Date and any
Option Closing Date will have, valid and marketable title to the Shares to be
sold by the Selling Stockholder, free and clear of any lien, claim, security
interest or other encumbrance, including, without limitation, any restriction on
transfer, except as otherwise described in the Prospectuses.

         (b)  The Selling Stockholder now has, and on the Closing Date and any
Option Closing Date will have, full legal right, power and authorization, and
any approval required by law, to sell, assign, transfer and deliver such Shares
in the manner provided in this Agreement and the International Underwriting
Agreement, and upon delivery of and payment for such Shares hereunder, the
several Managers will acquire valid and marketable title to such Shares free and
clear of any lien, claim, security interest, or other encumbrance.

         (c)  This Agreement, and the U.S. Underwriting Agreement have been
duly authorized, executed and delivered by or on behalf of the Selling
Stockholder and are the valid and binding agreements of the Selling Stockholder
enforceable against the Selling Stockholder in accordance with their terms,
except that (i) the enforceability hereof or thereof may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereafter in effect relating to creditors' rights generally, (ii) the remedy of
specific performance and other forms of equitable relief may be subject to
certain equitable defenses and to the discretion of the court before which the
proceedings may be brought and (iii) rights to indemnity and contribution
hereunder or thereunder may be limited by federal or state securities laws or
the public policy underlying such laws.

         (d)  Neither the sale of the Shares, the execution, delivery or
performance of this Agreement, or the U.S. Underwriting Agreement by or on
behalf of the Selling Stockholder nor the consummation by or on behalf of the
Selling Stockholder of the transactions contemplated hereby and thereby
(i) requires any consent, approval, authorization or other order of, or
registration or filing with, any court, regulatory body, administrative agency
or other governmental body, agency or official (except such as may be required
for the registration of the Shares under the Act or compliance with the
securities or Blue Sky laws of various jurisdictions or except as already
obtained), or (ii) conflicts or will conflict with or constitutes or will
constitute a breach of, or a default under, any agreement, indenture, lease or
other instrument to which the Selling Stockholder is a party or by which the
Selling Stockholder is or may be bound, or violates or will violate any

                                      -14-

<PAGE>

statute, law, regulation or filing or judgment, injunction, order or decree
applicable to the Selling Stockholder, or will result in the creation or
imposition of any lien, charge or encumbrance upon any property or assets of the
Selling Stockholder pursuant to the terms of any agreement or instrument to
which the Selling Stockholder is a party or by which the Selling Stockholder may
be bound or to which any of the property or assets of the Selling Stockholder is
subject.

         (e)  The information pertaining to the Selling Stockholder provided to
the Company for inclusion under the caption "Principal and Selling Stockholders"
in the Prospectuses, does not and will not contain an untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein not misleading.

         (f)  The Selling Stockholder has not taken, directly or indirectly,
any action designed to or that might reasonably be expected to cause or result
in stabilization or manipulation of the price of the Common Stock to facilitate
the sale or resale of the Shares, except for the lock-up arrangements referred
to in the Prospectuses.

         (g)  The Selling Stockholder does not have any knowledge or any reason
to believe that the Registration Statement or the Prospectuses (or any amendment
or supplement thereto) contains any untrue statement of a material fact or omits
to state any material fact required to be stated therein or necessary to make
the statements therein not misleading.

    9.   INDEMNIFICATION AND CONTRIBUTION.  (a) The Company and the Selling
Stockholder, jointly and severally, agree to indemnify and hold harmless you and
each other Manager and each person, if any, who controls any Manager within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act from and
against any and all losses, claims, damages, liabilities and expenses (including
reasonable costs of investigation) arising out of or based upon any untrue
statement or alleged untrue statement of a material fact contained in any
International Prepricing Prospectus or in the Registration Statement or the
International Prospectus or in any amendment or supplement thereto, or arising
out of or based upon any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, except insofar as such losses, claims, damages,
liabilities or expenses arise out of or are based upon any untrue statement or
omission or alleged untrue statement or omission which has been made therein or
omitted therefrom in reliance upon and in conformity with the information
relating to such Manager or U.S. Underwriter furnished in writing to the Company
by or on behalf of any Manager through you as Lead Managers or by or on behalf
of any U.S. Underwriter through the Representatives expressly for use in
connection therewith; provided, that with respect to the Selling Stockholder,
only to the extent that any such loss, liability, claim, damage or expense
arises out of or is based upon any untrue statement or alleged untrue statement
or an omission or alleged omission made therein in reliance upon and in
conformity with written information relating to the Selling Stockholder
furnished to the Company or the U.S. Underwriters by the Selling Stockholder
expressly for use in any Prepricing Prospectus or in the Registration Statement
or the U.S. Prospectus or in any amendment or supplement thereto; provided,
further, however, that the indemnification contained in this paragraph (a) with
respect to any International Prepricing Prospectus shall not inure to the
benefit of any Manager (or to the benefit of any person controlling such
Manager) on account of any such loss, claim, damage, liability or expense
arising from the sale of the Shares by such Manager to any person if a copy of
the International Prospectus shall not have been delivered or sent to such
person within the time required by the Act and the regulations thereunder, and
the untrue statement or alleged untrue statement or omission or alleged omission
of a material fact contained in such International Prepricing Prospectus was
corrected in the International Prospectus, provided that the Company has
delivered the

                                      -15-

<PAGE>

International Prospectus to the several Managers in a reasonable quantity on a
timely basis to permit such delivery or sending.  The foregoing indemnity
agreement shall be in addition to any liability which the Company or the Selling
Stockholder may otherwise have.

    (b)  If any action, suit or proceeding shall be brought against any Manager
or any person controlling any Manager in respect of which indemnity may be
sought against the Company or the Selling Stockholder, such Manager or such
controlling person shall promptly notify the parties against whom
indemnification is being sought (the "indemnifying parties"), and such
indemnifying parties shall assume the defense thereof, including the employment
of counsel and payment of all fees and expenses.  Such Manager or any such
controlling person shall have the right to employ separate counsel in any such
action, suit or proceeding and to participate in the defense thereof, but the
fees and expenses of such counsel shall be at the expense of such Manager or
such controlling person unless (i) the indemnifying parties have agreed in
writing to pay such fees and expenses, (ii) the indemnifying parties have failed
to assume the defense and employ counsel, or (iii) the named parties to any such
action, suit or proceeding (including any impleaded parties) include both such
Manager or such controlling person and the indemnifying parties and such Manager
or such controlling person shall have been advised by its counsel in writing
that representation of such indemnified party and any indemnifying party by the
same counsel would be inappropriate under applicable standards of professional
conduct (whether or not such representation by the same counsel has been
proposed) due to actual or potential differing interests between them (in which
case the indemnifying party shall not have the right to assume the defense of
such action, suit or proceeding on behalf of such Manager or such controlling
person).  It is understood, however, that the indemnifying parties shall, in
connection with any one such action, suit or proceeding or separate but
substantially similar or related actions, suits or proceedings in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of only one separate firm of
attorneys (in addition to any local counsel) at any time for all such Managers
and controlling persons not having actual or potential differing interests with
you or among themselves, which firm shall be designated in writing by Smith
Barney Inc., and that all such fees and expenses shall be reimbursed as they are
incurred.  The indemnifying parties shall not be liable for any settlement of
any such action, suit or proceeding effected without their written consent, but
if settled with such written consent, or if there be a final judgment for the
plaintiff in any such action, suit or proceeding, the indemnifying parties agree
to indemnify and hold harmless any Manager, to the extent provided in the
preceding paragraph, and any such controlling person from and against any loss,
claim, damage, liability or expense by reason of such settlement or judgment.

    (c)  Each Manager agrees, severally and not jointly, to indemnify and hold
harmless the Company, its directors, its officers who sign the Registration
Statement, any person who controls the Company within the meaning of Section 15
of the Act or Section 20(a) of the Exchange Act and the Selling Stockholder, to
the same extent as the foregoing indemnity from the Company and the Selling
Stockholder to each Manager, but only with respect to information relating to
such Manager furnished in writing by or on behalf of such Manager through you
expressly for use in the Registration Statement, the International Prospectus or
any International Prepricing Prospectus, or any amendment or supplement thereto.
If any action, suit or proceeding shall be brought against the Company, any of
its directors, any such officer, any such controlling person or the Selling
Stockholder, based on the Registration Statement, the International Prospectus
or any International Prepricing Prospectus, or any amendment or supplement
thereto, and in respect of which indemnity may be sought against any Manager
pursuant to this paragraph (c), such Manager shall have the rights and duties
given to the Company and the Selling Stockholder by paragraph (b) above (except
that if the Company or the Selling Stockholder shall have assumed the defense
thereof such Manager shall not be required to do so, but may employ separate
counsel therein and participate in the defense thereof,

                                      -16-

but the fees and expenses of such counsel shall be at such Manager's expense),
and the Company, its directors, any such officer, any such controlling person,
and the Selling Stockholder shall have the rights and duties given to the
Managers by paragraph (b) above.   The foregoing indemnity agreement shall be in
addition to any liability which the Managers may otherwise have.

    (d)  If the indemnification provided for in this Section 9 is unavailable
to an indemnified party under paragraphs (a) or (c) hereof in respect of any
losses, claims, damages, liabilities or expenses referred to therein, then an
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or expenses (i) in such proportion
as is appropriate to reflect the relative benefits received by the Company and
the Selling Stockholder on the one hand and the Managers on the other hand from
the offering of the Shares, or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the Company and the Selling Stockholder on the one
hand and the Managers on the other hand in connection with the statements or
omissions that resulted in such losses, claims, damages, liabilities or
expenses, as well as any other relevant equitable considerations.  The relative
benefits received by the Company and the Selling Stockholder on the one hand and
the Managers on the other hand shall be deemed to be in the same proportion as
the total net proceeds from the offering (before deducting expenses) received by
the Company and the Selling Stockholder bear to the total underwriting discounts
and commissions received by the Managers, in each case as set forth in the table
on the cover page of the International Prospectus; provided that, in the event
that the Managers shall have purchased any Additional Shares hereunder, any
determination of the relative benefits received by the Company, the Selling
Stockholder or the Managers from the offering of the Shares shall include the
net proceeds (before deducting expenses) received by the Selling Stockholder,
and the underwriting discounts and commissions received by the Managers, from
the sale of such Additional Shares, in each case computed on the basis of the
respective amounts set forth in the notes to the table on the cover page of the
International Prospectus.  The relative fault of the Company and the Selling
Stockholder on the one hand and the Managers 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 supplied by the Company or the Selling
Stockholder on the one hand or by the Managers on the other hand and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

    (e)  The Company, the Selling Stockholder and the Managers agree that it
would not be just and equitable if contribution pursuant to this Section 9 were
determined by a pro rata allocation (even if the Managers were treated as one
entity for such purpose) or by any other method of allocation that does not take
account of the equitable considerations referred to in paragraph (d) above.  The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities and expenses referred to in paragraph (d) above
shall be deemed to include, subject to the limitations set forth above, any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating any claim or defending any such action, suit or
proceeding.  Notwithstanding the provisions of this Section 9, no Manager shall
be required to contribute any amount in excess of the amount by which the total
price of the Shares underwritten by it and distributed to the public exceeds the
amount of any damages which such Manager has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission.  Notwithstanding the provisions of this Section 9, the Selling
Stockholder shall not be required to contribute any amount in excess of the
aggregate proceeds received by such Selling Stockholder from the sale of its
Shares pursuant to this Agreement (net of underwriting discounts and commissions
and after deducting expenses).  No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled

                                      -17-

<PAGE>

to contribution from any person who was not guilty of such fraudulent
misrepresentation.  The Managers' obligations to contribute pursuant to this
Section 9 are several in proportion to the respective numbers of Firm Shares set
forth opposite their names in Schedule II hereto (or such numbers of Firm Shares
increased as set forth in Section 12 hereof) and not joint.

    (f)  No indemnifying party shall, without the prior written consent of the
indemnified party, effect any settlement of any pending or threatened action,
suit or proceeding in respect of which any indemnified party is or could have
been a party and indemnity could have been sought hereunder by such indemnified
party, unless such settlement includes an unconditional release of such
indemnified party from all liability on claims that are the subject matter of
such action, suit or proceeding.

    (g)  Any losses, claims, damages, liabilities or expenses for which an
indemnified party is entitled to indemnification or contribution under this
Section 9 shall be paid by the indemnifying party to the indemnified party as
such losses, claims, damages, liabilities or expenses are incurred.  The
indemnity and contribution agreements contained in this Section 9 and the
representations and warranties of the Company and the Selling Stockholder set
forth in this Agreement shall remain operative and in full force and effect,
regardless of (i) any investigation made by or on behalf of any Manager or any
person controlling any Manager, the Company, its directors or officers or the
Selling Stockholder, any director, officer or partner of the Selling Stockholder
or any person controlling the Company or the Selling Stockholder, (ii)
acceptance of any Shares and payment therefor hereunder, and (iii) any
termination of this Agreement.  A successor to any Manager or any person
controlling any Manager, or to the Company, its directors or officers, or to the
Selling Stockholder, any director, officer or partner of the Selling Stockholder
or any person controlling the Company or the Selling Stockholder, shall be
entitled to the benefits of the indemnity, contribution and reimbursement
agreements contained in this Section 9.

    10.  CONDITIONS OF MANAGERS' OBLIGATIONS.  The several obligations of the
Managers to purchase the Firm Shares hereunder are subject to the following
conditions:

         (a)  If, at the time this Agreement is executed and delivered, it is
necessary for the Registration Statement or a post-effective amendment thereto
or an Additional Registration Statement to be declared effective before the
offering of the Shares may commence, the Registration Statement or such
post-effective amendment or Additional Registration Statement shall have become
effective not later than 5:30 P.M., New York City time, on the date hereof, or
at such later date and time as shall be consented to in writing by you, and all
filings, if any, required by Rules 424 and 430A under the Act shall have been
timely made; no stop order suspending the effectiveness of the Registration
Statement shall have been issued and no proceeding for that purpose shall have
been instituted or, to the knowledge of the Company or any Manager, threatened
by the Commission, and any request of the Commission for additional information
(to be included in the Registration Statement or the Prospectuses or otherwise)
shall have been complied with to your satisfaction.

         (b)  Subsequent to the effective date of this Agreement, there shall
not have occurred (i) any change, or any development involving a prospective
change, that would have a Material Adverse Effect on the Company and the
Subsidiaries, taken as a whole, not contemplated by the Prospectuses, which in
your opinion, as Lead Managers for the several Managers, makes it impracticable
or inadvisable to proceed with an offering of the Shares.

                                      -18-

<PAGE>

         (c)  You shall have received on the Closing Date an opinion of B.
Curtis Westen, Senior Vice President, General Counsel and Secretary for the
Company dated the Closing Date and addressed to you, as Lead Managers for the
several Managers, to the effect that:

              (i)       Each Subsidiary is a corporation duly organized and
validly existing and in good standing under the laws of the jurisdiction of its
organization, with full power and authority to own, lease, and operate its
properties and to conduct its business as described in the Registration
Statement and the Prospectuses (and any amendment or supplement thereto); and
all the outstanding shares of capital stock of each of the Subsidiaries have
been duly authorized and validly issued, are fully paid and nonassessable, and
are owned of record by the Company directly, or indirectly through one of the
other Subsidiaries, free and clear of any security interest, lien, adverse
claim, equity or other encumbrance, except as referred to in the Registration
Statement and the Prospectuses (or any amendment or supplement thereto);

              (ii)      The Company and each Subsidiary is duly registered and
qualified to conduct its business and is in good standing as a foreign
corporation in each jurisdiction where the nature of its properties or the
conduct of its business requires such registration or qualification, except
where the failure so to register or qualify or to be in good standing does not
have a Material Adverse Effect;

              (iii)     All the shares of capital stock of the Company
outstanding prior to the issuance of the Shares have been duly authorized and
validly issued and are fully paid and nonassessable;

              (iv)      Neither the Company nor any of the Subsidiaries is (a)
in violation of its certificate of incorporation or bylaws, or other
organizational documents, nor (b) is in default in the performance of any
material obligation, agreement or condition contained in any bond, debenture,
note or other evidence of indebtedness, except as disclosed in the Registration
Statement or Prospectuses (or any amendment or supplement thereto);

              (v)       Neither the offer, sale or delivery of the Shares, nor
the execution, delivery or performance of the International Underwriting
Agreement or the U.S. Underwriting Agreement, nor compliance by the Company with
the provisions thereof, nor consummation by the Company of the transactions
contemplated thereby conflicts or will conflict with or constitutes or will
constitute a breach of, or a default under, in any material respect, the
certificate of incorporation or bylaws, or other organizational documents of the
Company or any of the Subsidiaries or any agreement, indenture, lease or other
instrument to which the Company or any of the Subsidiaries is a party or by
which any of them or any of their respective properties is bound that is made an
exhibit to the Registration Statement or to any Incorporated Document, or is
known to such counsel after reasonable inquiry, or will result in the creation
or imposition of any lien, charge or encumbrance upon any property or assets of
the Company or any of the Subsidiaries, nor will any such action result in any
violation of any existing law, regulation, ruling (assuming compliance with all
applicable state securities and Blue Sky laws), judgment, injunction, order or
decree known to such counsel after reasonable inquiry, and applicable to the
Company, the Subsidiaries, or any of their respective properties, except where
any of the foregoing would not have a Material Adverse Effect;

              (vi)      Each of the Company and each Subsidiary has full
corporate power and authority and, to such counsel's knowledge after reasonable
inquiry, such Permits as are required, (A) under such federal and state
healthcare laws as are applicable to the Company or any of the Subsidiaries to
own, lease and operate their respective properties and to conduct their
respective businesses as described in the Prospectuses, and (B) with respect to
those facilities owned, leased or managed by the Company or any


                                      -19-

<PAGE>

Subsidiary that participates in Medicare and/or Medicaid, to receive
reimbursement thereunder, except where the failure to so possess any such
Permits would not, singularly or in the aggregate, have a Material Adverse
Effect;

              (vii)     To the knowledge of such counsel, neither the Company
nor any of the Subsidiaries is in violation of any healthcare law, ordinance,
administrative or governmental rule or regulation applicable to them,
respectively,  or of any decree of any court or governmental agency or body
having jurisdiction over them relating thereto, respectively, and, in the course
of such counsel's representation of the Company or any Subsidiary, nothing has
come to such counsel's attention to cause it to believe that the Company or any
Subsidiary is in violation of any other law, ordinance, administrative or
governmental rule or regulation applicable to it or of any decree of any court
or governmental agency or body having jurisdiction over it which could have a
Material Adverse Effect;

              (viii)    There are no legal or governmental actions, suits,
claims, proceedings or investigations pending or, to the knowledge of the
Company, threatened, against the Company or any of the Subsidiaries or against
or involving any of its officers, directors or employees in connection with the
business or affairs of the Company, including, without limitation, any claims
for indemnification arising under any agreement to which the Company is a party,
which are materially adverse to the Company or any of its Subsidiaries, or to
which the Company or any of the Subsidiaries, or to which any of their
respective properties, is subject which are material to the Company and its
Subsidiaries, taken as a whole (including, without limitation, any proceeding to
revoke or deny renewal of any Permits (as defined herein) of the Company or any
of the Subsidiaries), that are required to be described in the Registration
Statement or the Prospectuses but are not described as required, and there are
no agreements, contracts, indentures, leases or other instruments relating to
the Company that are required to be described in the Registration Statement or
the Prospectuses or to be filed as an exhibit to the Registration Statement or
any Incorporated Document that are not described or filed as required by the Act
or the Exchange Act.  The descriptions of the terms of any such contracts or
documents contained in the Registration Statement or the Prospectuses are
accurate in all material respects.   The Company is not subject to or in default
with respect to any writ, order, judgment, injunction or decree which is
materially adverse to the Company or any of its Subsidiaries;

              (ix)      Each of the Incorporated Documents (except for the
financial statements and the notes thereto and the schedules and other financial
and statistical data included therein, as to which counsel need not express any
opinion) complies as to form in all material respects with the Exchange Act and
the rules and regulations of the Commission thereunder; and


              (x)       The statements in the Registration Statement and
Prospectuses or any Incorporated Document, insofar as they are descriptions of
contracts, agreements or other legal documents, or refer to statements of law or
legal conclusions, are accurate in all material respects and present fairly the
information required to be shown.

         In addition, such counsel shall state that although such counsel has
not undertaken, except as otherwise indicated in his opinion, to determine
independently, and does not assume any responsibility for, the accuracy,
completeness or fairness of the statements in the Registration Statement, such
counsel has participated in the preparation of the Registration Statement and
the Prospectuses, including review and discussion of the contents thereof
(including review and discussion of the contents of all Incorporated Documents),
and no facts have come to the attention of such counsel that would lead him to
believe that the

                                      -20-

<PAGE>

Registration Statement (including the Incorporated Documents) at the time the
Registration Statement became effective, or the Prospectuses as of their
respective dates and as of the Closing Date or the Option Closing Date, as the
case may be, contained an untrue statement of a material fact or omitted or
omits to state a material fact necessary in order to make the statements therein
not misleading or that any amendment or supplement to the Prospectuses, as of
its respective date, and as of the Closing Date or the Option Closing Date, as
the case may be, contained or contains an untrue statement of a material fact or
omitted or omits to state a material fact required to be stated in the
Prospectuses or necessary in order to make the statements therein, in the light
of the circumstances under which they were made, not misleading (it being
understood that such counsel need express no opinion with respect to the
financial statements and the notes thereto and the schedules and other financial
and statistical data included in the Registration Statement or the Prospectuses
or any Incorporated Documents).


         In rendering such opinion as aforesaid, such counsel may, as to
matters of law, rely upon an opinion or opinions, each dated the Closing Date,
of other counsel retained by him or the Company as to laws of any jurisdiction
other than the United States or the State of California or the corporation law
of the State of Delaware, provided that (1) each such local counsel is
reasonably acceptable to the Lead Managers, (2) such reliance is expressly
authorized by each opinion so relied upon and a copy of each such opinion is
delivered to the Lead Managers and is, in form and substance reasonably
satisfactory to them and their counsel, and (3) such counsel shall state in his
opinion that he believes that they and the Managers are justified in relying
thereon.

         (d)  You shall have received on the Closing Date an opinion from
McDermott, Will & Emery, Special Counsel to the Company, dated the Closing Date
and addressed to you, as Lead Managers for the several Managers, to the effect
that:

              (i)       The Company is a corporation duly organized and validly
existing in good standing under the laws of the State of Delaware with full

Prospectuses;

              (ii)      The authorized capital stock of the Company is as set

legal matters to the description thereof contained in the Prospectuses under the
caption "Description of Capital Stock";

              (iii)     The Shares to be issued and sold to the U.S.

and, when issued and delivered to the U.S. Underwriters and Managers against
payment therefor in accordance with the terms of the U.S. Underwriting Agreement
and the International Underwriting Agreement will be validly issued, fully paid
and nonassessable and free of any (A) preemptive rights or (B) to the best
knowledge of such counsel after reasonable inquiry, similar rights that entitle
or will entitle any person to acquire any Shares upon the issuance thereof by
the Company;

              (iv)      The form of certificates for the Shares conforms to the
requirements of the Delaware General Corporation Law;

                                      -21-

<PAGE>

              (v)       The Registration Statement and all post-effective
amendments, if any, have become effective under the Act and, to the best
knowledge of such counsel after reasonable inquiry, no stop order suspending the
effectiveness of the Registration Statement has been issued and no proceedings
for that purpose are pending before or contemplated by the Commission; and any
required filing of the Prospectuses pursuant to Rule 424(b) has been made in
accordance with Rule 424(b);

              (vi)      The Company has the corporate power and authority to
enter into the U.S. Underwriting Agreement and the International Underwriting
Agreement and to issue, sell and deliver the Shares to be sold by it to the U.S.
Underwriters and Managers as provided therein, and each of the U.S. Underwriting
Agreement and the International Underwriting Agreement have been duly
authorized, executed and delivered by the Company and is a legal, valid and
binding agreement of the Company, enforceable against the Company in accordance
with its terms, except as enforcement of rights to indemnity and contribution
hereunder may be limited by federal or state securities laws or principles of
public policy and subject to the qualification that the enforceability of the
Company's obligations hereunder may be limited by bankruptcy, fraudulent
conveyance, insolvency, reorganization, moratorium and other laws relating to or
affecting creditors' rights generally and by general equitable principles;

              (vii)     No consent, approval, authorization or other order of,
or registration or filing with, any court, regulatory body, administrative
agency or other governmental body, agency, or official is required on the part
of the Company (except as have been obtained under the Act and the Exchange Act
or such as may be required under state securities or Blue Sky laws governing the
purchase and distribution of the Shares) for the valid issuance and sale of the
Shares to the Managers as contemplated by the International Underwriting
Agreement;

              (viii)    (A) The Registration Statement and the Prospectuses and
any supplements or amendments thereto (except for the financial statements and
notes thereto and the schedules and other financial and statistical data
included therein, as to which such counsel need not express any opinion) comply
as to form in all material respects with the requirements of the Act; and (B)
each of the Incorporated Documents (except for (1) the financial statements and
the notes thereto and the schedules and other financial and statistical data
included therein and (2) the Company's two Current Reports on Form 8-K each
dated March 15, 1995, the Company's Current Report on Form 8-K dated December 8,

1996, the Company's Current Report on Form 8-K dated April 10, 1996, and the
Company's Current Report on Form 8-K dated May 3, 1996, in each case as to which
counsel need not express any opinion) complies as to form in all material
respects with the Exchange Act and the rules and regulations of the Commission
thereunder;

              (ix)      Except as described in or contemplated by the
Prospectuses, such counsel does not know of any outstanding option, warrant or
other right calling for the issuance of, and such counsel does not know of any
commitment, plan or arrangement to issue, any shares of capital stock of the
Company or any securities convertible into or exchangeable or exercisable for
capital stock of the Company (other than the issuance of Common Stock upon
exercise of options under the Company's stock option plans described in the
Prospectus); and except as described in the Prospectuses, such counsel does not
know of any holder of any security of the Company or any other person who has
the right, contractual or otherwise, to cause the Company to sell or otherwise
issue to them, or permit them to underwrite the sale of, any of the Shares or
the right (other than any such right which has been complied with by the Company
or waived) to have any Common Stock or other securities of the Company included
in the Registration Statement or the

                                      -22-

<PAGE>

right, as a result of the filing of the Registration Statement or otherwise, to
require registration under the Act of any shares of Common Stock or other
securities of the Company; and

              (x)       The Company is not and, upon sale of the Shares to be
issued and sold by the Company pursuant to this Agreement and the U.S.
Underwriting Agreement and upon application of the net proceeds therefrom as
described in the Prospectuses under the caption "Use of Proceeds" will not be,
an "investment company" or a person "controlled" by an "investment company"
within the meaning of the Investment Company Act of 1940, as amended.

         In addition, such counsel shall state that although such counsel has
not undertaken, except as otherwise indicated in their opinion, to determine
independently, and does not assume any responsibility for, the accuracy,
completeness or fairness of the statements in the Registration Statement, such
counsel has participated in the preparation of the Registration Statement and
the Prospectuses, including review and discussion of the contents thereof
(including review and discussion of the contents of all Incorporated Documents),
and no facts have come to the attention of such counsel that would lead them to
believe that the Registration Statement (including the Incorporated Documents)
at the time the Registration Statement became effective, or the Prospectuses as
of their respective dates and as of the Closing Date or the Option Closing Date,
as the case may be, contained an untrue statement of a material fact or omitted
or omits to state a material fact necessary in order to make the statements
therein not misleading or that any amendment or supplement to the Prospectuses,
as of its respective date, and as of the Closing Date or the Option Closing
Date, as the case may be, contained or contains an untrue statement of a
material fact or omitted or omits to state a material fact required to be stated
in the Prospectuses or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading (it being
understood that such counsel need express no opinion with respect to the
financial statements and the notes thereto and the schedules and other financial
and statistical data included in the Registration Statement or the Prospectuses
or any Incorporated Documents).

         The opinion of such counsel may be limited to the laws of the United
States and the State of New York, State of California, the corporation laws of
the State of Delaware, and to the laws of certain other jurisdictions applicable
to the Company or a Subsidiary to the extent covered by an opinion or opinions,
each dated the Closing Date or the Option Closing Date, as the case may be, of
other counsel retained by them or the Company as to the laws of such other
jurisdiction, upon which such counsel may rely, provided that (1) each such
local counsel is acceptable to the Lead Managers, (2) such reliance is expressly
authorized by each opinion so relied upon and a copy of each such opinion is
delivered to the Lead Managers and is, in form and substance satisfactory to
them and their counsel, and (3) counsel shall state in their opinion that they
believe that they and the Managers are justified in relying thereon.

         (e)  You shall have received on the Closing Date an opinion of Manatt,
Phelps & Phillips, LLP, special counsel for the Selling Stockholder, dated the
Closing Date and addressed to you, as Lead Managers for the several Managers, to
the effect that:

              (i)       The U.S. Underwriting Agreement and the International
Underwriting Agreement have each been duly executed and delivered by or on
behalf of the Selling Stockholder and are valid and binding agreements of the
Selling Stockholder enforceable against the Selling Stockholder in accordance
with their respective terms, except (A) as enforcement of rights to indemnity
and contribution hereunder and thereunder may be limited by federal or state
securities laws or principles of public policy and (B) subject to the
qualification that the enforceability of each of their obligations hereunder and

                                      -23-

<PAGE>

thereunder may be limited by bankruptcy, fraudulent conveyance, insolvency,
reorganization, moratorium and other laws relating to or affecting creditors'
rights generally and by general equitable principles;

              (ii)      To the knowledge of such counsel, the Selling
Stockholder has full legal right, power and authorization and any approval
required by law to sell, assign, transfer and deliver good and marketable title
to the Shares the Selling Stockholder has agreed to sell pursuant to this
Agreement; and upon delivery of such Shares pursuant to the U.S. Underwriting
Agreement and the International Underwriting Agreement and payment therefor as
contemplated herein and assuming that the several U.S. Underwriters and Managers
are bona fide purchasers within the meaning of the Uniform Commercial Code as in
effect in the State of New York (the "UCC"), the U.S. Underwriters will acquire
good and marketable title to such Shares free and clear of any adverse claim
(within the meaning of Section 8-302 of the U.C.C.); and

              (iii)     To the knowledge of such counsel, the execution and
delivery of the U.S. Underwriting Agreement and the International Underwriting
Agreement by the Selling Stockholder and the consummation of the transactions
contemplated hereby and thereby will not conflict with, violate, result in a
breach of or constitute a default under the terms or provisions of any
agreement, indenture, mortgage or other instrument to which the Selling
Stockholder is a party or by which it or any of its assets or property is bound,
or any court order or decree or any law, rule, or regulation known to such
counsel applicable to the Selling Stockholder or to any of the respective
property or assets of the Selling Stockholder.

         In addition, such counsel shall state that although such counsel has
not undertaken, except as otherwise indicated in their opinion, to determine
independently, and does not assume any responsibility for, the accuracy,
completeness or fairness of the statements in the Registration Statement with
respect to the Selling Stockholder, such counsel has participated in the
preparation of the Registration Statement and the Prospectuses, including review
and discussion of the contents thereof (including review and discussion of the
contents of all Incorporated Documents with respect to the Selling Stockholder),
and no facts have come to the attention of such counsel that would lead them to
believe that, insofar as such relates to the Selling Stockholder, the
Registration Statement (including the Incorporated Documents) at the time the
Registration Statement became effective, or the Prospectuses as of their
respective dates and as of the Closing Date or the Option Closing Date, as the
case may be, contained an untrue statement of a material fact or omitted or
omits to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading or that any amendment or supplement to the Prospectuses, as of its
respective date, and as of the Closing Date or the Option Closing Date, as the
case may be, contained or contains an untrue statement of a material fact or
omitted or omits to state a material fact required to be stated in the
Prospectuses or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading (it being
understood that such counsel need express no opinion with respect to the
financial statements and the notes thereto and the schedules and other financial
and statistical data included in the Registration Statement or the Prospectuses
or any Incorporated Documents or any other information regarding the Company).

         The opinion of such counsel may be limited to the laws of the United
States and the State of California, the corporation laws of the State of
Delaware, and to the laws of certain other jurisdictions applicable to the
Selling Stockholder to the extent covered by an opinion or opinions, each dated
the Closing Date or the Option Closing Date, as the case may be, of other
counsel retained by them or the Company as to the laws of such other
jurisdiction, upon which such counsel may rely, provided that (1) each such
local counsel is acceptable to the Lead Managers, (2) such reliance is expressly
authorized by each opinion so relied upon and a copy of each such opinion is
delivered to the Lead Managers and is, in form and substance

Underwriter) in connection with presentations to prospective purchasers of the
Shares; and (ix) the fees and expenses of the Company's accountants and the fees
and expenses of counsel (including local and special counsel) for the Company
and the Selling Stockholder; provided that nothing in this Section 11 shall

determine any such costs or expenses.

    12.  EFFECTIVE DATE OF AGREEMENT.  This Agreement shall become effective:
(i) upon the execution and delivery hereof by the parties hereto; or (ii) if, at
the time this Agreement is executed and delivered, it is necessary for the
registration statement or a post-effective amendment thereto or an Additional
Registration Statement to be declared effective before the offering of the
Shares may commence, when notification of the effectiveness of the registration
statement or such post-effective amendment or Additional Registration Statement
has been released by the Commission.  Until such time as this Agreement shall
have become effective, it may be terminated by the Company, by notifying you, or
by you, as Lead Managers for the several Managers, by notifying the Company and
the Selling Stockholder.

         If any one or more of the Managers shall fail or refuse to purchase
Shares which it or they are obligated to purchase hereunder on the Closing Date,
and the aggregate number of Shares which such defaulting Manager or Underwriters
are obligated but fail or refuse to purchase is not more than one-tenth of the
aggregate number of Shares which the Managers are obligated to purchase on the
Closing Date, each non-defaulting Manager shall be obligated, severally, in the
proportion which the number of Firm Shares set forth opposite its name in
Schedule II hereto bears to the aggregate number of Firm Shares set forth
opposite the names of all non-defaulting Managers or in such other proportion as
you may specify in accordance with Section 20 of the Master Agreement Among
Underwriters of Smith Barney Inc., to purchase the Shares which such defaulting
Manager or Underwriters are obligated, but fail or refuse, to purchase.  If any
one or more of the Managers shall fail or refuse to purchase Shares which it or
they are obligated to purchase on the Closing Date and the aggregate number of
Shares with respect to which such default occurs is more than one-tenth of the
aggregate number of Shares which the Managers are obligated to purchase on the
Closing Date and arrangements satisfactory to you and the Company for the
purchase of such Shares by one or more non-defaulting Managers or other party or
parties approved by you and the Company are not made within 36 hours after such
default, this Agreement will terminate without liability on the part of any
non-defaulting Manager or the Company.  In any such case which does not result
in termination of this Agreement, either you or the Company shall have the right
to postpone the Closing Date, but in no event for longer than seven days, in
order that the required changes, if any, in the Registration Statement and the
Prospectus or any other documents or arrangements may be effected.  Any action
taken under this paragraph shall not relieve any defaulting Manager from
liability in respect of any such default of any such Underwriter under this
Agreement.  The term "Manager" as used in this Agreement includes, for all
purposes of this Agreement, any party not listed in Schedule II hereto who, with
your approval and the approval of the Company, purchases Shares which a
defaulting Manager is obligated, but fails or refuses, to purchase.

    Any notice under this Section 12 may be given by telegram, telecopy or
telephone but shall be subsequently confirmed by letter.

    13.  TERMINATION OF AGREEMENT.  This Agreement shall be subject to
termination in your absolute discretion, without liability on the part of any
Manager to the Company or the Selling Stockholder, by notice to the Company, if
prior to the Closing Date or any Option Closing Date (if different from the
Closing Date and then only as to the Additional Shares), as the case may be, (i)
trading in the Common Stock of the

                                      -27-

<PAGE>

Company shall be suspended or subject to any restriction or limitation not in
effect on the date of this Agreement; (ii) trading in securities generally on
the New York Stock Exchange, the American Stock Exchange or the Nasdaq National
Market shall have been suspended or materially limited; (iii) a general
moratorium on commercial banking activities in New York shall have been declared
by either federal or state authorities; or (iv) there shall have occurred any
outbreak or escalation of hostilities or other international or domestic
calamity, crisis or change in political, financial or economic conditions, the
effect of which on the financial markets of the United States is such as to make
it, in your judgment, impracticable or inadvisable to commence or continue the
offering of the Shares at the offering price to the public set forth on the
cover page of the International Prospectus or to enforce contracts for the
resale of the Shares by the Managers.

    Notice of such termination may be given by telegram, telecopy or telephone
and shall be subsequently confirmed by letter.

    14.  INFORMATION FURNISHED BY THE MANAGERS.  The statements set forth in
the last paragraph on the cover page, the stabilization legend on the inside
front cover page, and the statements in the second and fourth paragraphs under
the caption "Underwriting" in any International Prepricing Prospectus and in the
International Prospectus constitute the only information furnished by or on
behalf of the Managers through you as such information is referred to in
Sections 7(b) and 9 hereof.

    15.  MISCELLANEOUS.  Except as otherwise provided in Sections 5, 12 and 13
hereof, notice given pursuant to any provision of this Agreement shall be in
writing and shall be delivered (i) if to the Company, at the office of the
Company at [21600 Oxnard Street, Woodland Hills, California 91367], with a copy
to McDermott, Will & Emery, 227 West Monroe St., Chicago, Illinois 60606-5906,

10013, Attention: Manager, Investment Banking Division, with a copy to Dewey
Ballantine, 333 South Hope Street, 30th Floor, Los Angeles, CA 90071, Attention:
Robert M. Smith, Esq.


    This Agreement has been and is made solely for the benefit of the several
Managers, the Company, its directors and officers, the other controlling persons
referred to in Section 9 hereof and the Selling Stockholders and their
respective successors and assigns, to the extent provided herein, and no other
person shall acquire or have any right under or by virtue of this Agreement.
Neither the term "successor" nor the term "successors and assigns" as used in
this Agreement shall include a purchaser from any Manager of any of the Shares
in his status as such purchaser.

    16.  APPLICABLE LAW; COUNTERPARTS.  This Agreement shall be governed by and
construed in accordance with the laws of the State of New York applicable to
contracts made and to be performed within the State of New York.

    This Agreement may be signed in various counterparts which together
constitute one and the same instrument.  If signed in counterparts, this
Agreement shall not become effective unless at least one counterpart hereof
shall have been executed and delivered on behalf of each party hereto.

     Re:  Registration Statement on Form S-1
          File No. 333-2788
          ------------------------------------------------

Ladies and Gentlemen:

     You have requested our opinion in connection with the above-referenced 
registration statement (the "Registration Statement"), under which (i) Health 
Systems International, Inc. (the "Company") intends to issue and sell in the 
offering related thereto 3,194,374 shares (the "Primary Shares") of Class A 
Common Stock, par value $.001 per share, of the Company ("Common Stock") and 
(ii) a stockholder of the Company intends to sell in the offering 5,136,830 
shares of Class A Common Stock, plus up to an additional 1,249,680 shares of 
Class A Common Stock granted to the underwriters by the selling stockholders 
to cover over-allotments (the "Secondary Shares").

     In arriving at the opinion expressed below, we have examined the 
Registration Statement and such other documents as we have deemed necessary 
to enable us to express the opinion hereinafter set forth. In addition, we 
have examined and relied, to the extent we deem proper, on certificates of 
officers of the Company as to factual matters, and on the originals or copies 
certified or otherwise identified to our satisfaction, of all such corporate 
records of the Company and such other instruments and certificates of public 
officials and other persons as we have deemed appropriate. In our 
examination, we have assumed the authenticity of all documents submitted to
us as originals, the conformity to the original documents of all documents 
submitted to us as copies, the genuineness of all signatures on documents 
reviewed by us and the legal capacity of natural persons.

     Based upon and subject to the foregoing, we are of the opinion that (i) 
the Primary Shares have been duly authorized and, when 

<PAGE>

Health Systems International, Inc.

Page 2

issued in accordance with the terms and conditions set forth in the 
Registration Statement, will be validly issued, fully paid and 
non-assessable, and (ii) the Secondary Shares have been duly authorized and 
validly issued and are fully paid and non-assessable.

     We hereby consent to the reference to our firm under the caption "Legal 
Matters" in the Registration Statement and to the use of this opinion as an 
exhibit to the Registration Statement. In giving this consent, we do not 
hereby admit that we come within the category of persons whose consent is 
required under Section 7 of the Securities Act of 1933, as amended, or the 
rules and regulations of the Securities and Exchange Commission thereunder.

                                       Very truly yours,
