ITEM 1.       BUSINESS
                                                      GENERAL

Sierra Health  Services,  Inc.  ("Sierra")  and its  subsidiaries  (collectively
referred  to as the  "Company"),  is a managed  health  care  organization  that
provides and administers the delivery of comprehensive  health care and workers'
compensation programs with an emphasis on quality care and cost management.  The
Company's  strategy has been to develop and offer a portfolio of managed  health
care and workers' compensation products to employer groups and individuals.  The
Company's  broad range of managed  health care services is provided  through its
federally qualified and non-qualified health maintenance organizations ("HMOs"),
managed  indemnity  plans,  a third-party  administrative  services  program for
employer-funded  health benefit plans,  workers' compensation medical management
programs and a subsidiary  that  administers a managed care federal  contact for
the  Department  of  Defense's  TRICARE  program in Region 1. This  contract  is
currently  structured as five one-year option periods. If all option periods are
exercised  by  the  Department  of  Defense  ("DOD")  and no  extensions  of the
performance  period are made,  health care delivery will end on May 31, 2003 for
Region 1. Ancillary  products and services that complement the Company's managed
health care and workers' compensation product lines are also offered.

On October 31, 1998,  Sierra and one of its  subsidiaries,  Texas Health Choice,
L.C.  ("TXHC"),  (formerly HMO Texas L.C.)  completed the acquisition of certain
assets of Kaiser Foundation Health Plan of Texas ("Kaiser-Texas"), a health plan
operating in Dallas/Ft. Worth with approximately 109,000 members, and Permanente
Medical Association of Texas ("Permanente"),  a medical group with approximately
150 physicians. The purchase price was $124 million, which is net $20 million in
operating  cost support to be paid to Sierra by Kaiser  Foundation  Hospitals in
five  quarterly  installments  following  the  closing of the  transaction.  The
purchase  price  includes  amounts for real estate and eight  medical and office
facilities  with  approximately  500,000 square feet. In December 1998,  certain
accreditation  goals were met by the health plan  resulting in a purchase  price
increase of $3.0 million, to $127 million. The purchase price may increase up to
an  additional  $27  million  over  three  years if  certain  growth  and member
retention goals are met by the health plan.  Sierra assumed no prior liabilities
for malpractice or other litigation, or for any unanticipated future adjustments
to claims  expenses for periods prior to closing.  The  transaction was financed
with a five-year  revolving  credit facility and a $35.2 million note payable to
Kaiser Foundation Health Plan of Texas. The note is secured by the acquired real
estate. Approximately $110 million of the $200 million revolving credit facility
was used to fund the transaction.

On December 31, 1998, Sierra completed the acquisition of the Nevada health care
business of Exclusive Healthcare,  Inc. ("EHI"),  United of Omaha Life Insurance
Company and United World Life  Insurance  Company  ("United"),  all of which are
subsidiaries of Mutual of Omaha Insurance Company. Sierra retained approximately
9,000 members  (approximately  4,400 HMO members) subsequent to the acquisition.
On January 27, 1999, Sierra signed a definitive  agreement to purchase the Texas
operations of EHI (6,900 HMO members) and United's  related  preferred  provider
organization  ("PPO")  that  is  part  of the  dual  option  HMO/PPO  plan.  The
transaction  is  expected  to be  completed  no later than April 30, 1999 and is
subject to regulatory  approvals.  The purchase  price of both  transactions  is
contingent based on how many members are retained through 2000 and 2001. No cash
will be paid until group renewals begin in 2000.

On September  30, 1997,  Sierra  Military  Health  Services,  Inc.  ("SMHS") was
awarded a TRICARE  contract to provide  managed health care coverage to eligible
beneficiaries in Region 1. In June 1998, the Company began providing health care
benefits to approximately 606,000 individuals in Connecticut,  Delaware,  Maine,
Maryland,  Massachusetts,  New Hampshire,  New Jersey,  New York,  Pennsylvania,
Rhode Island, Vermont, Virginia, West Virginia and Washington, D.C. In 1998, the
award resulted in a total of approximately $204.8

                                                         1

million of revenue for the final  five-months  of the  implementation  phase and
seven  months of health care  delivery.  SMHS was  notified on February 13, 1998
that  the  United  States  General   Accounting   Office  ("GAO")   sustained  a
competitor's  protest of the  contract  award for TRICARE  Managed  Care Support
Region 1 and  recommended  that the contract be re-bid.  In December  1998,  the
Company  reached an agreement to settle the protest (See Note 14 of Notes to the
Consolidated  Financial Statements).  As part of the settlement,  the competitor
will forego any and all rights it may have to challenge  the contract  award and
seek a re-bid.

The principal  executive offices of the Company are located at 2724 North Tenaya
Way, Las Vegas, Nevada 89128, and its telephone number is (702) 242-7000.

Managed Care Products and Services

The Company's  primary types of health care coverage are HMO plans, HMO Point of
Service ("POS") plans, and managed indemnity plans,  which include a PPO option.
As of December 31,  1998,  the Company  provided  HMO products to  approximately
182,000  members in Nevada,  112,000 in Dallas,  25,000 in Houston  and 5,000 in
Arizona.  The POS products  allow members to choose one of the various  coverage
options  when medical  services are required  instead of one plan for the entire
year.  The Company also provides  managed  indemnity  products to  approximately
41,000 members,  Medicare supplement  products to approximately  26,000 members,
and administrative  services to approximately 318,000 members.  Medical premiums
account  for  approximately  59% of total  revenues.  Approximately  70% of such
medical premiums were derived from southern Nevada in 1998. With the acquisition
of  Kaiser-Texas,  medical premiums derived from southern Nevada in November and
December of 1998 were approximately 57% of medical premium revenue.

Health Maintenance Organizations. The Company operates mixed group network model
HMOs in Las Vegas, Nevada and Dallas/Ft. Worth, Texas and a network model HMO in
Reno,  Nevada  and  Houston,  Texas.  Contracted  primary  care  physicians  and
specialists   for  the  HMOs  are   compensated  on  a  capitation  or  modified
fee-for-service   basis.  Contracts  with  their  primary  hospitals  are  on  a
capitation  or  discounted  per diem  basis.  Members  receive  a wide  range of
coverage after paying a nominal  co-payment and are eligible for preventive care
coverage. The HMOs do not require deductibles or claim forms.

Most of the  Company's  managed  health  care  services  in Nevada are  provided
through its  independently  contracted  network of over 2,200  providers  and 13
hospitals.  These Nevada networks include the Company's  multi-specialty medical
group,  which provides medical  services to  approximately  71% of the Company's
Nevada HMO members and employs  over 170  primary  care and other  providers  in
various medical  specialties.  The Company  directly  provides home health care,
hospice  care and  behavioral  health care  services and operates a company that
provides  home  infusion,  oxygen and durable  medical  equipment  services.  In
addition,  the Company  operates three 24-hour urgent care centers,  a radiology
department,  a vision department,  an occupational  medicine  department and two
free-standing,  state-licensed and Medicare-approved ambulatory surgery centers.
The Company believes that this vertical  integration of its health care delivery
system in Nevada provides a competitive  advantage as it has helped it to manage
health care costs effectively while delivering quality care.

On October 31, 1998,  the Company  acquired  certain assets of  Kaiser-Texas,  a
group model HMO with  approximately  109,000 members and a 150 physician medical
group in Dallas/Ft.  Worth,  Texas. The independently  contracted  medical group
provides  professional  services from nine health centers;  eight of which offer
primary care services while two offer specialty care services. In addition, TXHC
has contracts with 13 hospitals for inpatient care in Dallas/Ft.  Worth. Shortly
after the  acquisition,  the Company  changed the provider  model in  Dallas/Ft.
Worth  from a group  model to a mixed  network  model by  overlaying  individual
practice association ("IPA") delivery systems on top of the existing group model
to provide  members with more choice.  The first IPA was  contracted in November
1998 and added approximately

                                                         2

<PAGE>



1,500  physicians  to the  Dallas/Ft.  Worth  delivery  system.  The Houston HMO
members are served by approximately 1,600 independent  contracted  providers and
30 hospitals.

In addition to its commercial HMO plans, which involve  traditional HMO benefits
and  POS   benefits,   the   Company   offers  a  Medicare   risk   product  for
Medicare-eligible  beneficiaries called Senior Dimensions in Nevada and parts of
Arizona and Golden Choice in Texas.  Senior  Dimensions is marketed  directly to
Medicare-eligible  beneficiaries in the Company's Nevada service area as well as
contiguous  parts of Arizona.  The monthly payment received from the Health Care
Financing  Administration  ("HCFA")  is  determined  by formula  established  by
Federal law. The Balanced Budget Act of 1997 included  legislative changes which
affected  the  way  health  plans  are  compensated  for  Medicare   members  by
eliminating over five years amounts paid for graduate  medical  education and by
increasing  the blend of national  cost  factors  applied in  determining  local
reimbursement  rates over a six-year phase-in period. Both changes will have the
effect of reducing  reimbursement in high cost  metropolitan  areas with a large
number of teaching hospitals;  however, the legislation includes a provision for
a minimum increase of 2% annually in health plan Medicare  reimbursement for the
next five years.  Under the authority  provided by the 1997 Balanced  Budget Act
(see "Government Regulation and Recent Legislation"),  HCFA has begun to collect
hospital encounter data from Medicare risk contractors. The data will be used to
implement  a new  risk  adjustment  mechanism  which  will be  phased  in over a
five-year period  beginning  January 1, 2000. Given the relatively high Medicare
risk premium levels in certain of the Company's  market areas, the Company is in
jeopardy that the new risk adjustment  mechanism to be developed could adversely
affect the Company's Medicare premium rates going forward.  The Company does not
believe  that the risk  adjustment  mechanism  will be  applied  to  Social  HMO
capitation payments.

As of December  31,  1998,  the Company had 47,000  Medicare  members,  of which
33,500  were   located  in  Nevada,   8,300  in  Texas  and  5,200  in  Arizona.
Approximately  26,000 of the Nevada  Medicare  members were enrolled in a Social
Health Maintenance  Organization (see "Social Health  Maintenance  Organization"
following).

Social Health Maintenance Organization.  Effective November 1, 1996, the Company
entered  into a Social HMO  contract  pursuant  to which a large  portion of the
Company's Medicare risk enrollees will receive certain expanded benefits. Sierra
was one of six HMOs nationally to be awarded this contract, and is currently the
only  company to have  implemented  the program as of  December  31,  1998.  The
Company receives additional revenues for providing these expanded benefits.  The
additional  revenues are determined  based on health risk  assessments that have
been, and will continue to be, performed on the Company's eligible Medicare risk
members.  The additional  benefits  include,  among other things,  assisting the
eligible  Medicare  risk  members with typical  daily living  functions  such as
bathing,  dressing and walking.  These members, as identified in the health risk
assessments,  are those who  currently  have  difficulty  performing  such daily
living functions because of a health or physical problem. HCFA has expressed the
intention to continue the current  reimbursement  methodology for the Social HMO
contract  through   December  31,  2000.  HCFA  has  considered   adjusting  the
reimbursement  factors for the Social HMO members. At this time, however,  there
can be no  assurance  as to what the final per member  reimbursement  will be or
that the social HMO contract will be renewed.

Preferred  Provider  Organizations.  The Company  also offers  health  insurance
through its PPO. The Company's  managed indemnity plans generally offer insureds
the  option of  receiving  their  medical  care from  either  non-contracted  or
contracted  providers.  Insureds  pay higher  deductibles  and  co-insurance  or
co-payments when they receive care from non-contracted providers.  Out-of-pocket
costs  are  lowered  by  utilizing  contracted  providers  who  are  part of the
Company's PPO network.  As of December 31, 1998,  approximately  41,000  members
were enrolled in Sierra's managed indemnity plans.

The  Company  currently  provides  managed  indemnity  and  Medicare  supplement
services  to  individuals  in  Nevada,  Arizona,  Colorado,  Texas,  California,
Louisiana,  Iowa and South  Carolina.  The  Company  is also  exploring  further
expansion  in  certain  other  states and  currently  provides  other  insurance
services in Missouri, New Mexico, and Pennsylvania.  As of December 31, 1998 the
PPO is licensed in a total of 43 states and the District of Columbia.

Ancillary Medical Services.  Among the ancillary medical services offered by the
Company are outpatient  surgical care,  diagnostic  tests,  medical and surgical
procedures, inpatient and outpatient laboratory tests, x-ray, CAT scans, nuclear
medicine  services,  and mental health and substance abuse services.  In Nevada,
the Company  also  provides  home health care  services,  a hospice  program and
vision  services.  These services are provided to members of the Company's HMOs,
managed  indemnity  and  administrative  services  plans.  The mental health and
substance abuse services are also provided to approximately 137,000 participants
from non-affiliated  employer groups and insurance companies.  In addition,  the
Company offers home infusion, oxygen and durable medical equipment services.

Administrative Services. The Company's administrative services products provide,
among other things, utilization review and PPO services to large employer groups
that are usually  self-insured.  As of December 31, 1998,  approximately 318,000
members  were  enrolled in the  Company's  administrative  services  plans.  The
results of  operations  for these  services are  included in  specialty  product
revenues and expenses in the Consolidated Statements of Operations.

Workers' Compensation Operations

Workers' Compensation Subsidiary.  On October 31, 1995, the Company acquired CII
Financial,  Inc. ("CII"),  for approximately  $76.3 million of common stock in a
transaction  accounted  for as a  pooling  of  interests.  CII  writes  workers'
compensation insurance in the states of California,  Colorado, Kansas, Missouri,
Nebraska,  New  Mexico,  Texas and Utah.  CII has  licenses in 31 states and the
District of Columbia.  California,  Colorado, and Texas represent  approximately
84%, 8%, and 5%,  respectively,  of CII's fully  insured  workers'  compensation
insurance premiums in 1998. Workers' compensation insurance premiums account for
approximately  13% of the Company's  total  revenue.  The workers'  compensation
subsidiary  applies the  discipline of managed care concepts to its  operations.
These concepts include, but are not limited to, the use of specialized preferred
provider networks,  utilization reviews by employed board certified occupational
medicine and orthopedic  surgeons as well as nurse case  managers,  medical bill
reviewers and job developers who facilitate early return to work.

Effective  September 30, 1997, the Company terminated its workers'  compensation
administrative  services contract with the state of Nevada.  The contract served
approximately  200,000  enrollees  and  provided  approximately  $3.2 million in
revenues for the year ended  December 31, 1997.  The contract was  terminated to
allow the Company to participate in the Nevada workers'  compensation  insurance
market when the state  allows  private  insurance  companies  to begin  offering
products on July 1, 1999.

Military Contract Services

Sierra  Military  Health  Services,  Inc. On September 30, 1997, the Company was
awarded a TRICARE  contract to provide  managed health care coverage to eligible
beneficiaries in Region 1. This region includes  approximately  606,000 eligible
individuals  in  Connecticut,  Delaware,  Maine,  Maryland,  Massachusetts,  New
Hampshire, New Jersey, New York, Pennsylvania,  Rhode Island, Vermont, Virginia,
West Virginia and Washington,  D.C. SMHS completed an eight month implementation
phase in May 1998 and began providing health care benefits on June 1, 1998 under
the TRICARE contract.

Under the TRICARE contract,  SMHS provides health care services to approximately
606,000  dependents of active duty military  personnel and military retirees and
their dependents through  subcontractor  partnerships and individual  providers.
Through such partnerships,  SMHS also performs specific administrative services,
such as health care appointment scheduling,  enrollment,  network management and
health  care  advice  line  services.  SMHS  performs  such  services  using DOD
information  systems. If all five option periods are exercised by the DOD and no
extensions of the performance  period are made, health care delivery will end on
May 31, 2003,  followed by an  additional  eight month  phaseout of the Region 1
managed care support contract.

Marketing

The Company's marketing efforts for its commercial managed care products involve
a two-step process.  The Company first makes presentations to employers and then
provides  information  directly to  employees  once the  employer has decided to
offer the Company's  products.  Once a relationship  with a group is established
and a group agreement is negotiated and signed, the Company's  marketing efforts
focus on individual employees. During a designated "open enrollment" period each
year,  usually the month  preceding the annual renewal of the agreement with the
group,  employees  choose  whether  to  remain  with,  join or  terminate  their
membership  with a specific  health plan offered by the employer.  New employees
decide whether to join one of the  employers'  health  insurance  options at the
time of their  employment.  Although  contracts  with  employers  are  generally
terminable on 60 days notice,  changes in membership occur primarily during open
enrollment  periods.  Medicare risk products are primarily marketed by the HMOs'
sales  employees.   Retention  of  employer  groups  and  membership  growth  is
accomplished  through  print  advertising  directed  to  employers  and  through
consumer media campaigns.  Media communications convey the Company's emphasis on
preventive  care,  ready access to health care  providers  and quality  service.
Other  communications  to customers  include  employer  and member  newsletters,
member  education  brochures,  prenatal  information  packets,   employer/broker
seminars and direct mail  advertising  to clients.  Members'  satisfaction  with
Company  benefits and services is  monitored by customer  surveys.  Results from
these  surveys and other  primary  and  secondary  research  guide the sales and
advertising efforts throughout the year.

The  Company's  workers'  compensation  insurance  policies  are sold  primarily
through independent  insurance agents and brokers,  who may also represent other
insurance companies.  The Company believes that independent insurance agents and
brokers choose to market the Company's  insurance  policies primarily because of
the price the Company charges.  Additional considerations include the quality of
service that the Company  provides and the  commissions  the Company  pays.  The
Company  employs  full-time  employees  as  marketing  representatives  to  make
personal  contacts with agents and brokers,  to maintain  regular  communication
with them, to advise them of the Company's services and products, and to recruit
additional agents and brokers. In addition,  the Company employs full-time field
underwriters who meet with agents and brokers and can provide an immediate quote
on a policy.  As of  December  31,  1998,  the Company  had  relationships  with
approximately  730  agents  and 20  brokers  and paid  its  agents  and  brokers
commissions  based on a percentage of the gross written premium produced by such
agents and brokers.  The Company also  utilizes a number of  promotional  media,
including advertising in publications and at trade fairs, to support the efforts
of its independent agents.

SMHS administers  marketing  initiatives in accordance with the TRICARE Region 1
managed  care  support  contract.  SMHS'  dedicated  Marketing  Division  uses a
multi-faceted  marketing approach to ensure that all beneficiaries within Region
1 have the opportunity to learn about the health care benefits under TRICARE and
have the  opportunity  to make health care choices that best fit their  specific
needs. Marketing initiatives include direct beneficiary briefings,  direct mail,
newspaper advertising, newsletters and web page briefs.

(1)  For  comparability  purposes,  enrollment  information has been restated to
     reflect  the  September  30, 1997  termination  of the  Company's  workers'
     compensation  administrative  services  contract  with the state of Nevada.
     Enrollment in the terminated plan was 163,000, 94,000 and 79,000 members at
     December 31, 1996, 1995 and 1994, respectively.

For  the  years  ended  December  31,  1998  and  1997,  the  Company   received
approximately  23.0% and 23.7%,  respectively,  of its total  revenues  from its
contract with HCFA to provide  health care services to Medicare  enrollees.  The
Company's  contract  with HCFA is subject to annual  renewal at the  election of
HCFA,  and requires the Company to comply with federal HMO and Medicare laws and
regulations  and may be  terminated  if the  Company  fails  to so  comply.  The
termination  of the Company's  contract with HCFA would have a material  adverse
effect on the Company's business. In addition,  there have been, and the Company
expects  that there will  continue to be, a number of  legislative  proposals to
limit Medicare reimbursements and to require additional benefits.  Future levels
of funding of the Medicare program by the federal government cannot be predicted
with certainty (See "Government Regulation and Recent Regulation").

The Company's ability to obtain and maintain  favorable group benefit agreements
with employer  groups  affects the Company's  profitability.  The agreements are
generally renewable on an annual basis but are subject to termination on 60 days
prior  notice.  For the fiscal year ended  December 31, 1998,  the Company's ten
largest HMO employer  groups were, in the aggregate,  responsible  for less than
10% of the Company's  total  revenues.  Although  none of such  employer  groups
accounted for more than 2% of total revenues during that period, the loss of one
or more of the larger  employer  groups  would,  if not  replaced  with  similar
membership,  have a material  adverse  effect upon the Company's  business.  The
Company has  generally  been  successful  in retaining  these  employer  groups.
However,  there can be no  assurance  that the Company will be able to renew its
agreements  with  such  employer  groups  in the  future  or that  it  will  not
experience a decline in  enrollment  within its employer  groups.  Additionally,
revenues  received under certain  government  contracts are subject to audit and
retroactive adjustment.

Provider Arrangements and Cost Management

HMO and  Managed  Indemnity  Products.  A  significant  distinction  between the
Company's  health  care  delivery  system  and that of many other  managed  care
providers is the fact that approximately 71% of the Company's Nevada HMO members
and 80% of its Texas  HMO  members  receive  primary  health  care  through  the
Company's  affiliated  multi-specialty  medical groups. The Company makes health
care  available  through  independently  contracted  providers  employed  by the
multi-specialty  medical groups and other  independently  contracted networks of
physicians, hospitals and other providers.

Under the  Company's  HMOs,  the member  selects a primary  care  physician  who
provides or  authorizes  any  non-emergency  medical  care given to that member.
These primary care physicians and some  specialists are compensated to a limited
extent on the basis of how well they  coordinate  appropriate  medical care. The
Company has a system of limited  incentive  risk  arrangements  and  utilization
management with respect

                                                         6

<PAGE>



to its independently contracted primary care physicians. The Company compensates
its  independently  contracted  primary care physicians and specialists by using
both capitation and modified  fee-for-service  payment methods. In Nevada, under
both the  capitation  and modified  fee-for-service  methods,  an incentive risk
arrangement is established for institutional services. Additional amounts may be
made available to certain  capitated  physicians if hospital costs are less than
anticipated  for the  Company's HMO members.  For those primary care  physicians
receiving payments on a modified fee-for-service basis, portions of the payments
otherwise due the  physicians are withheld.  The amounts  withheld are available
for  payment  to the  physicians  if, at  year-end,  the  expenditures  for both
institutional and  non-institutional  medical services are within predetermined,
contractually  agreed upon  ranges.  It is believed  that this method of limited
incentive risk payment is  advantageous  to the  physician,  the Company and the
members  because all share in the  benefits of managing  health care costs.  The
Company  has,  however,   negotiated  capitation  and  reduced   fee-for-service
agreements  with  certain  specialists  and primary  care  providers  who do not
participate in the incentive risk arrangements. The Company monitors health care
utilization,  including evaluation of elective surgical  procedures,  quality of
care and financial  stability of its capitated providers to facilitate access to
service and to ensure member satisfaction.

The  Company  also  believes  that it has  negotiated  favorable  rates with its
contracted  hospitals.  The  Company's  contracts  with its  hospital  providers
typically renew  automatically  with both parties granted the right to terminate
after  a  notice  period   ranging  from  between   three  and  twelve   months.
Reimbursement   arrangements   with  other  health  care  providers,   including
pharmacies,  generally renew  automatically  or are negotiated  annually and are
based on several  different  payment  methods,  including  per diems  (where the
reimbursement  rate  varies  and is based  on a per day of  service  charge  for
specified types of care), capitation or modified  fee-for-service  arrangements.
To the extent possible,  when negotiating  non-physician  provider arrangements,
the Company solicits competitive bids.

The Company provides,  or negotiates discounted contracts with hospitals for the
provision of, inpatient and outpatient hospital care,  including room and board,
diagnostic tests and medical and surgical procedures.  The Company believes that
it  currently  has  a  favorable  contract  with  its  primary  southern  Nevada
contracted hospital,  Columbia Sunrise Hospital. Subject to certain limitations,
the contract provides,  among other things,  guaranteed contracted per diem rate
increases  on an  annual  basis  after  December  31,  1997.  The per diem  rate
increased  1% in 1998 and is scheduled  for 2% in 1999.  Since a majority of the
Company's  southern Nevada hospital days are at Columbia Sunrise Hospital,  this
contract  assists the Company in managing a  significant  portion of its medical
costs.  The  contract  expires  in the year  2012.  In Texas,  the  Company  has
negotiated a capitation  arrangement with Columbia  Hospital,  Inc. for hospital
services  provided in Houston and has contracts  with 13 hospitals for inpatient
care in Dallas/Ft. Worth.

The  Company  utilizes  two  reimbursement  methods  for health  care  providers
rendering services under the Company's  indemnity plans. For services to members
utilizing  a PPO plan,  the Company  reimburses  participating  physicians  on a
modified  fee-for-service  basis which  incorporates  a limited fee schedule and
reimburses  hospitals on a per diem or  discounted  fee-for-service  basis.  For
services  rendered under a standard  indemnity plan,  pursuant to which a member
may select a non-plan provider, the Company reimburses non-contracted physicians
and  hospitals at  pre-established  rates,  less  deductibles  and  co-insurance
amounts.

The Company manages health care costs through its large case management program,
urgent  care  centers  and by  educating  its members on how and when to use the
services of its plans and how to manage chronic disease conditions.  The Company
also audits hospital bills to identify inappropriate charges. Further, in Nevada
the Company  utilizes its home health care agency and its hospice which helps to
minimize hospital admissions and lengths of stay.

Military Health Services. Under the TRICARE contract,  dependents of active duty
military  personnel  and military  retirees and their  dependents  choose one of
three option plans available to them for health care services: (1) TRICARE Prime
(an  HMO  style  option  with  a  self-selected  primary  care  manager  and  no
deductibles),  (2) TRICARE Extra (a PPO style option),  or (3) TRICARE  Standard
(an indemnity style option with deductibles and cost shares).  Approximately 30%
of eligible beneficiaries receive their primary care

                                                         7

<PAGE>



through  existing  Military  Treatment  Facilities.  SMHS negotiated  discounted
contracts with approximately 20,000 individual providers, 1,200 institutions and
5,000  pharmacies to provide  supplemental  network access for TRICARE Prime and
Extra  beneficiaries.   SMHS'  contracts  with  providers  are  primarily  on  a
discounted  fee-for-service  basis with renewal and termination terms similar to
Sierra's  commercial  practice.  SMHS is at-risk for and manages the health care
service cost of all TRICARE Extra and Standard  beneficiaries as well as a small
percentage of TRICARE Prime beneficiaries.

Risk Management

The Company maintains general and professional liability,  property and fidelity
insurance  coverage in amounts that it believes are adequate for its operations.
The  Company's   multi-specialty  medical  groups  maintain  excess  malpractice
insurance  for the  providers  presently  employed  by the group.  In Nevada and
Arizona, the Company has assumed the risk for the first $250,000 per malpractice
claim,  not to exceed $1.5 million in the  aggregate per contract year up to its
limits of coverage. In Texas, the Company has assumed no self-insured  retention
per claim.  The  aggregate  maximum  exposure for each of these  policies is $30
million per year.  In addition,  the Company  requires all of its  independently
contracted   provider   physician  groups,   individual   practice   physicians,
specialists,  dentists,  podiatrists  and other health care providers  (with the
exception of certain  hospitals) to maintain  professional  liability  coverage.
Certain of the hospitals with which the Company contracts are self-insured.  The
Company also maintains  stop-loss  insurance that reimburses the Company between
50% and 90% of hospital charges for each individual member of its HMO or managed
indemnity  plans whose  hospital  expenses  exceed,  depending on the  contract,
$100,000 to $200,000, during the contract year and up to $2.0 million per member
per lifetime.

Effective July 1, 1997, the Company also maintains excess catastrophic  coverage
for one of the Company's wholly-owned HMOs, Health Plan of Nevada, Inc. ("HPN"),
that  reimburses  the Company for amounts by which the ultimate net loss exceeds
$400,000,  but does not exceed the annual  maximum of $19.6 million per accident
and $39.2 million per contract. In the ordinary course of its business, however,
the Company is subject to claims that are not  insured,  principally  claims for
punitive damages.

Effective January 1, 1998,  workers'  compensation  claims are reinsured between
$500,000 and $100 million per occurrence. For claims occurring on and after July
1, 1998, that are below $500,000, the Company obtained quota share and excess of
loss reinsurance.  Under this agreement,  the Company reinsures 30% of the first
$10,000 of each claim,  75% of the next  $40,000 and 100% of the next  $450,000.
The  Company  receives  a ceding  commission  from the  reinsurer  as a  partial
reimbursement of operating expenses.

Information System

The Company has in place certain data systems which assist the Company in, among
other  things,  pricing  its  services,  monitoring  utilization  and other cost
factors,  providing bills on a timely basis, identifying accounts for collection
and  handling  various  accounting  and  reporting  functions.  Its  imaging and
workflow  systems are used to process and track claims and  coordinate  customer
service. Where it is cost efficient,  the Company's system is connected to large
provider  groups,  doctors'  offices,  payors and  brokers  to enable  efficient
transfer of information  and  communication.  The Company views its  information
systems  capability  as critical to the  performance  of ongoing  administrative
functions and integral to quality  assurance and to the  coordination of patient
care across care sites.  The Company is  continually  modifying or improving its
information systems capabilities in an effort to improve operating efficiencies.

Year 2000

The Year 2000 issue  exists  because  many  computer  systems  and  applications
currently  use  two-digit  date fields to designate a year.  As the century date
change occurs,  date-sensitive  systems will recognize the year 2000 as 1900, or
not at all.  This  inability to  recognize  or properly  treat the Year 2000 may
cause  systems  to  process  critical  financial  and  operational   information
incorrectly.


                                                         8

The Company is currently  in the process of  modifying or replacing  its mission
critical financial and operational  computer systems. The Company is also in the
process  of  testing  its  non-information   system  technology  for  Year  2000
compliance.  The Year 2000  project has been broken down into five  phases:  (1)
inventorying  Year  2000  items;  (2)  assessing  the Year 2000  items  that are
determined to be material to the Company;  (3) renovating or replacing  material
items  that are  determined  not to be Year  2000  compliant;  (4)  testing  and
validating material items; and (5) implementing renovated and validated systems.

At December 31, 1998,  the inventory  and  assessment  phases are  substantially
complete as it relates to all material  computer systems and  approximately  50%
complete  as it  relates  to  non-information  system  technology.  The  Company
estimates  that the  replacement/renovation  phases  and the  testing/validation
phases will be 95% complete by October 31, 1999.  The Company  estimates that it
is  approximately  50% complete  with the total project as of December 31, 1998.
Contingency  planning for the mission critical business  operations is scheduled
to be  completed  by the end of  April  1999.  These  plans  focus  on  business
operations   involving   information   systems   and   non-information   systems
technologies.

The Company has initiated formal  communications with entities with whom it does
business to assess  their Year 2000  issues.  Evaluations  of the most  critical
third  parties  have been  initiated,  and  follow-up  reviews will be conducted
through 1999.  Contingency  plans are being developed based on these evaluations
and are  expected  to be  completed  by the  middle  of  1999.  There  can be no
assurances that the systems of other companies or governmental agencies, such as
HCFA and the DOD, on which the Company  relies will be timely  modified for Year
2000, or that the failure to modify by another company would not have a material
adverse  effect on the Company.  Based upon two separate  reports  issued by the
United States General Accounting Office it is doubtful that the computer systems
at both HCFA and the DOD will be fully Year 2000  compliant  by the end of 1999.
The Company does not currently have available data to predict the impact of such
non-compliance on its business  operations.  Should there be any material delays
caused  by Year 2000  issues,  the  Company  anticipates  that the  governmental
entities will make estimated payments.

The  Company  is in the  process  of  implementing  three  major  systems  at an
estimated cost of $36 million to $38 million,  which includes the implementation
costs related to the recently  acquired  Kaiser-Texas  operations.  To date, the
Company has spent  approximately  $19.0 million on the new computer  systems and
other Year 2000 items. The Company is expensing the costs to make  modifications
to existing computer systems and non-computer  equipment.  Management  currently
estimates the  remaining new computer  system costs and other Year 2000 costs to
be $13.0  million to $16.0  million for  operations  in  existence  prior to the
Kaiser-Texas  transaction and $6.0 million to $8.0 million for the  Kaiser-Texas
operations  that were acquired on October 31, 1998.  While this is a substantial
effort,   it  will  give  the  Company  the  benefits  of  new   technology  and
functionality  for many of its financial and  operational  computer  systems and
applications.

The  failure  to  correct  a  material  Year  2000  problem  could  result in an
interruption  of, or a failure of,  certain  business  activities or operations.
Such  failures  could  materially  adversely  affect the  Company's  operations,
liquidity and financial  condition.  Due to the general uncertainty  inherent in
the Year  2000  problem,  resulting  in part from  uncertainty  of the Year 2000
readiness of third parties with which the Company does business,  the Company is
unable to determine at this time whether the consequences of potential Year 2000
failures  will have a  material  adverse  impact  on the  Company's  results  of
operations, liquidity or financial condition. The Company's Year 2000 project is
expected to  significantly  reduce the Company's level of uncertainty  about the
Year 2000 problem. The Company believes that, with the implementation of the new
computer  systems  and  completion  of the  entire  project  as  scheduled,  the
possibility of significant interruptions of operations should be reduced.

The above contains  forward-looking  statements  including,  without limitation,
statements   relating   to  the   Company's   plans,   strategies,   objectives,
expectations,  intentions, and adequate resources, that are made pursuant to the
"safe harbor"  provisions  of the Private  Securities  Litigation  Reform Act of
1995.  Readers are cautioned that  forward-looking  statements  contained in the
Year 2000 disclosure should be read in conjunction with the following disclosure
of the Company:


                                                         9

<PAGE>



The costs of the project  and the dates on which the  Company  plans to complete
the necessary Year 2000  modifications are based on management's best estimates,
which were derived utilizing numerous assumptions of future events including the
continued  availability of certain resources and other factors.  However,  there
can be no guarantee  that these  estimates  will be achieved and actual  results
could differ materially from those plans. Specific factors that might cause such
material  differences include, but are not limited to, the availability and cost
of  personnel  trained in this area,  the  ability  to locate  and  correct  all
relevant  computer codes,  the ability of the Company's  significant  suppliers,
customers  and others with which it  conducts  business,  including  federal and
state governmental  agencies, to identify and resolve their own Year 2000 issues
and similar uncertainties.

Quality Assurance and Improvement

The Company has developed  programs to help ensure that the health care services
provided by its HMO and managed indemnity plans meet the professional  standards
of care  established  by the medical  community.  The Company  believes that its
emphasis on quality  allows it to increase and retain its  members.  The Company
monitors and evaluates the availability and quality of the medical care rendered
by the providers in its HMO and insurance plans and periodically audits selected
diagnoses,   problems  and  referrals  to  determine  adherence  to  appropriate
standards of medical care. In addition,  the Company has medical  directors who,
supported   by  a   professional   medical   staff,   monitor  the  quality  and
appropriateness  of  health  care by  analyzing  a  physician's  utilization  of
diagnostic  tests,  laboratory and radiology  procedures,  specialty  referrals,
prescriptions  and  hospitals.  Physicians  and  hospitals  selected  to provide
services to the Company's members are subject to the Company's quality assurance
programs including a formal credentialing process of all physicians.

The  Company  also  has  internal  quality  assurance  and  improvement   review
committees that meet on a regular basis to review specialist referrals,  monitor
the performance of physicians and review practice patterns, complaints and other
patient  issues.  Staff  members  regularly  visit  hospitals to review  medical
records,  meet with patients and review  treatment  programs and discharge plans
with attending  physicians.  In addition,  the Company solicits information from
both  existing  and  former  members  as to  their  satisfaction  with  the care
delivered.  Complaints  and  grievances are responded to on both an informal and
formal basis, depending on the nature of the complaint.

Several independent organizations have been formed for the purpose of responding
to external demands for accountability in the health care industry.  The Company
has  voluntarily  elected  to be  evaluated  by  these  external  organizations,
including the National  Committee for Quality  Assurance  ("NCQA") and the Joint
Commission on Accreditation of Healthcare Organizations ("JCAHO").

NCQA is an independent,  not-for-profit organization that evaluates managed care
organizations.  The NCQA  accreditation  process includes  rigorous  evaluations
conducted  by a team of  physicians  and managed  care  experts.  No  comparable
evaluation exists for  fee-for-service  health care. The NCQA evaluates plans on
approximately  50  quality  standards  that  fall into six  categories:  Quality
Management  and  Improvement;   Physician   Credentials;   Members'  Rights  and
Responsibilities;  Preventive  Health  Services;  Utilization  Management;  and,
Medical  Records.  In 1998,  Health Plan of Nevada  ("HPN") earned a three-year,
full  accreditation  from the NCQA for its HMO and Medicare  products in the Las
Vegas  metropolitan area and Pahrump.  TXHC in Dallas/Ft.  Worth currently has a
One-Year Accreditation from NCQA, pending a May 1999 acquisition review.

     The JCAHO reviews rights,  responsibilities and ethics,  continuum of care,
education and communication,  leadership,  management of information,  and human
resources and network  performance.  The Company's  home health care and hospice
subsidiaries are JCAHO accredited.

There can be no assurance, however, that the Company will maintain NCQA or other
accreditations  in the future and there is no basis to predict what  effect,  if
any,  the lack of NCQA or other  accreditations  could  have on HPN's or  TXHC's
competitive   positions  in  southern   Nevada  and  Dallas/Ft.   Worth,   Texas
respectively.

Underwriting

HMO. The Company structures premium rates for its various health plans primarily
through  community  rating  and  community  rating  by class  method.  Under the
community  rating  method,  all costs of basic  benefit  plans for the Company's
entire  membership  population  are  aggregated.   These  aggregated  costs  are
calculated  on a "per member per month" basis and converted to premium rates for
various coverage types, such as single or family coverage.  The community rating
by class method is based on the same principles as community rating, except that
actuarial  adjustments  to  premium  rates are made for  demographic  variations
specific  to each  employer  group  such  as the  average  age and sex of  their
employees,  group size and  industry.  All  employees  of an employer  group are
charged the same premium rate if the same coverage is selected.

In  addition  to those  premium  charges  paid by the  employers  with  whom the
Company's  HMOs  contract,  members  also pay  co-payments  at the time  certain
services are  provided.  The Company  believes that such  co-payments  encourage
appropriate  utilization  of health care services  while allowing the Company to
offer  competitive  premium rates. The Company also believes that the capitation
method of provider compensation  encourages physicians to provide only medically
necessary and appropriate care.

Managed Indemnity.  Premium charges for the Company's managed indemnity products
are set in a manner  similar to the community  rating by class method  described
above. This rate calculation  utilizes similar  demographic  adjustment  factors
such as age, sex and industry factors to develop group-specific adjustments from
a given per member per month base rate by plan.  Actual health claims experience
is used in whole or in part to develop premium rates for larger insurance member
groups. This process includes the use of utilization experience, adjustments for
incurred but not reported claims, inflationary factors, credibility and specific
reinsurance pooling levels for large claims.

Workers' Compensation. Prior to insuring a particular risk, the Company reviews,
among other factors,  the employer's  prior loss  experience and premium payment
history.  Additionally, the Company determines whether the employer's employment
classifications  are among the  classifications  that the Company has elected to
insure generally and if the amounts of the premiums for the  classifications are
within the  Company's  guidelines.  The Company  reviews  these  classifications
periodically to evaluate whether they are profitable.  A member of the Company's
loss control  department  may conduct an on-site  safety  inspection  before the
Company insures the employer.  The Company  generally  initiates this inspection
for enterprises with manufacturing or construction classifications.  The Company
may also initiate  inspections if the enterprise  previously has had a high loss
ratio or frequent losses. If the on-site  inspection reveals hazards that can be
corrected,  and an agreement can be reached with the employer that these hazards
will be  corrected in a time frame  established  by the  Company's  underwriting
department,  the  Company  may issue a policy  subject  to  correction  of those
hazards.  In the  event  the  Company  has  issued  a policy  where no  previous
inspection has been conducted, and subsequently learns through an inspection the
employer has hazards that must be  corrected,  the Company will request that the
employer correct the hazards within a specified period of time. If these hazards
are not corrected,  the Company may cancel the policy for  non-compliance of the
hazard correction. With regard to new business, the agent or broker will usually
submit the claims history on the prospective  account. In those situations where
the claims  history is not supplied by the agent or broker,  other sources (such
as the prior  insurer)  are used to obtain  the  appropriate  claims  history if
possible.

Competition

HMO and Managed  Indemnity.  Managed care companies and HMOs operate in a highly
competitive  environment.  The Company's major  competition is from  self-funded
employer plans, PPO networks,  other HMOs, such as Humana Care Plus, Pacificare,
Inc., Aetna and Harris  Methodist and traditional  indemnity  carriers,  such as
Blue Cross/Blue  Shield.  Many of the Company's  competitors have  substantially
larger total enrollments,  have greater financial  resources and offer a broader
range  of  products  than  the  Company.  Additional  competitors  with  greater
financial  resources  than the  Company may enter the  Company's  markets in the
future. The Company believes that the most important competitive factors are the
delivery  of  reasonably  priced,  quality  medical  benefits to members and the
adequacy and availability of health care delivery  services and facilities.  The
Company depends on a large PPO network and flexible benefit plans

                                                        11

<PAGE>



to  attract  new  members.  Competitive  pressures  are  expected  to limit  the
Company's  ability to increase premium rates and, to a lesser extent,  to result
in declining premium rates. Accordingly,  the profitability of the Company will,
to a large  extent,  depend on the  Company's  ability  to  manage  the costs of
providing  health care benefits to its members.  The inability of the Company to
manage these costs would have an adverse impact on the Company's  future results
of operations by reducing margins. In addition,  competitive  pressures may also
result in reduced membership levels. Any such reductions could materially affect
the Company's results of operations.

Workers'   Compensation.   The  Company's  workers'   compensation  business  is
concentrated in California,  a state where the workers'  compensation  insurance
industry is  extremely  competitive.  Since open  rating  became  effective  for
policyholders  in  1995,  there  have  been,  and  continue  to be,  substantial
reductions  in  premiums.  The  Company  believes  that  there are more than 200
insurance companies writing workers' compensation insurance in California.  Many
of the Company's  competitors have been in business longer, have a larger volume
of business,  offer a more diversified line of insurance coverage,  have greater
financial resources and have greater  distribution  capability than the Company.
The largest writer of workers' compensation insurance in California is the State
Compensation Insurance Fund.

In all states in which the Company is currently  writing  business,  competition
for workers' compensation insurance is primarily driven by price and secondarily
by services provided to insureds and agents. In states other than California and
Texas,  the National Council on Compensation  Insurance  ("NCCI") is usually the
designated rating organization. The NCCI accumulates statistical information and
recommends pure loss costs to the state's  Department of Insurance.  The Company
then selects loss cost multiplier, expense loads to derive premium rates. Rating
plans in those  states are more  "standardized"  and are usually  based on plans
developed by the NCCI.

Losses and Loss Adjustment Expenses

Often, in workers' compensation insurance,  several years may elapse between the
occurrence  of a loss  and  the  final  settlement  of the  loss.  To  recognize
liabilities  for unpaid  losses,  the Company  establishes  reserves,  which are
balance sheet liabilities representing estimates of future amounts needed to pay
claims and related  expenses for insured events,  including  reserves for events
that have been incurred but have not yet been reported to the Company ("incurred
by not reported" or "IBNR").

When a claim is reported,  the Company's  claims personnel  initially  establish
reserves  on a  case-by-case  basis for the  estimated  amount  of the  ultimate
payment.  These estimates  reflect the judgment of the claims personnel based on
their  experience  and knowledge of the nature and value of the specific type of
claim and the available  facts at the time of reporting as to severity of injury
and initial medical  prognosis.  Included in these reserves are estimates of the
expenses of settling  claims,  including  legal and other fees,  and the general
expenses of administering the claims adjustment process. Claims personnel adjust
the amount of the case reserves as the claim develops and as the facts warrant.

IBNR  reserves  are  established  for  unreported  claims  and loss  development
relating to current  and prior  accident  years.  In the event that a claim that
occurred  during  a prior  accident  year was not  reported  until  the  current
accident year, the case reserve for such claim typically will be established out
of previously established IBNR reserves for that prior accident year.

The  Company  reviews  the  adequacy  of its  reserves  on a  monthly  basis and
considers  external  forces  such  as  changes  in the  rate of  inflation,  the
regulatory environment, the judicial administration of claims, medical costs and
other  factors  that could  cause  actual  losses and loss  adjustment  expenses
("LAE") to change.  Reserves are reviewed with the Company's independent actuary
at least  annually.  The  actuarial  projections  include  a range of  estimates
reflecting the uncertainty of projections.  Management evaluates the reserves in
the aggregate, based upon the actuarial indications, and makes adjustments where
appropriate. The

                                                        12

<PAGE>



consolidated  financial  statements of the Company provide for reserves based on
the anticipated ultimate cost of losses.

     Once an employer is insured by the  Company,  the  Company's  loss  control
department may assist the insured in developing and maintaining  safety programs
and procedures to minimize  on-the-job  injuries and industrial  health hazards.
The safety programs and procedures  vary from insured to insured.  The Company's
loss control  department  may recommend to the employer that a safety  committee
consisting of members of the employer's  management  staff and its general labor
force be established.  The Company's loss control department may then assist the
committee members in isolating safety hazards,  advising the committee on how to
correct the hazards and  assisting  the employer in  establishing  procedures to
enforce the corrections.  The Company's loss control department may also revisit
the employer to determine  whether the  recommended  corrections  and procedures
have  been  implemented.  Depending  upon the  size,  classifications,  and loss
experience  of  the  employer,   the  Company's  loss  control  department  will
periodically inspect the employer's places of business and may recommend changes
that could  prevent  industrial  accidents.  In  addition,  severe or  recurring
injuries may also warrant on-site inspections. In certain instances,  members of
the Company's loss control department may conduct special  educational  training
sessions for  insureds'  employees  to assist in the  prevention  of  on-the-job
injuries.  For  example,  employers  engaged in  manufacturing  may be offered a
training  session  on how to  prevent  back  injuries  or  employers  engaged in
contracting  may be  offered  a  training  session  on  general  first  aid  and
prevention of injuries that may result from specific work exposures.

Government Regulation and Recent Legislation

HMOs and Managed Indemnity.  Federal and state governments have enacted statutes
extensively  regulating the activities of HMOs. In addition,  growing government
concerns  over  increasing  health care costs and quality could result in new or
additional state or federal legislation that could affect health care providers,
including  HMOs,  PPOs and other health  insurers.  Among the areas regulated by
federal and state law are the scope of benefits  available  to members,  premium
structure,  procedures for review of quality assurance, enrollment requirements,
the  relationship  between an HMO and its health  care  providers  and  members,
licensing and financial condition.

Government  regulation  of health  care  coverage  products  and  services  is a
changing area of law that varies from  jurisdiction to jurisdiction.  Changes in
applicable  laws  and  regulations   are   continually   being   considered  and
interpretation  of  existing  laws and rules also may change  from time to time.
Regulatory agencies generally have broad discretion in promulgating  regulations
and in interpreting and enforcing laws and regulations.

While the Company is unable to predict what regulatory  changes may occur or the
impact on the Company of any  particular  change,  the Company's  operations and
financial  results could be negatively  affected by  regulatory  revisions.  For
example,  any  proposals  affecting   underwriting   practices,   limiting  rate
increases,  requiring  new  or  additional  benefits  or  affecting  contracting
arrangements  (including proposals to require HMOs and PPOs to accept any health
care providers  willing to abide by an HMO's or PPO's contract terms) may have a
material adverse effect on the Company's business.  The continued  consideration
and enactment of  "anti-managed  care" laws and regulations by federal and state
bodies may make it more  difficult for the Company to control  medical costs and
may adversely affect financial results.

In  addition  to changes in  applicable  laws and  regulations,  the  Company is
subject to various audits, investigations and enforcement actions. These include
possible  government actions relating to the federal Employee  Retirement Income
Security Act, which  regulates  insured and  self-insured  health coverage plans
offered by employers,  the Federal  Employees  Health Benefit Plan,  federal and
state fraud and abuse laws, and laws relating to utilization  management and the
delivery  of  health  care  and  payment  or  reimbursement  therefor.  Any such
government action could result in assessment of damages, civil or criminal fines
or

                                                        13

<PAGE>



penalties,  or  other  sanctions,  including  exclusion  from  participation  in
government  programs.  In addition,  disclosure of any adverse  investigation or
audit results or sanctions could negatively  affect the Company's  reputation in
various  markets and make it more difficult for the Company to sell its products
and services.

The Company has HMO licenses in Nevada,  Texas and Arizona.  The  Company's  HMO
operations  are subject to regulation by the Nevada  Division of Insurance,  the
Nevada  Division of Health,  the Texas  Department  of Insurance and the Arizona
Department of Insurance.  The Company's health insurance subsidiary is domiciled
and  incorporated in California and is licensed in 43 states and the District of
Columbia, with current operations primarily in Nevada, Arizona, Colorado, Texas,
California,  Louisiana,  Iowa and South Carolina. It is subject to licensing and
other  regulations  of the  California  Department  of  Insurance as well as the
insurance  departments  of other states in which it operates or holds  licenses.
The Company's  premium rate  increases  are subject to various  state  insurance
department  approvals.  The Company's HMO and  insurance  subsidiaries  are also
required by state regulatory agencies to maintain certain deposits and must also
meet  certain net worth and reserve  requirements.  The Company also has certain
other  deposit  requirements.  The Company has  restricted  assets on deposit in
various states ranging from $20,000 to $2.0 million and totalling  $17.8 million
at  December  31,  1998.  The  Company's  HMO and  insurance  subsidiaries  meet
requirements to maintain minimum  stockholder's equity ranging from $1.1 million
to $5.2 million. In addition, in conjunction with the Kaiser-Texas  acquisition,
TXHC  entered into a letter  agreement  with the Texas  Department  of Insurance
whereby  TXHC agreed to  maintain a net worth of $20.0  million.  The  Company's
Nevada HMO and health insurance subsidiaries currently maintain home offices and
a  regional  home  office,  respectively,  in Las Vegas  and,  accordingly,  are
eligible for certain premium tax credits in Nevada.

The Company's HMO subsidiaries are also restricted by state law as to the amount
of dividends that can be declared and paid.  Moreover,  insurance  companies and
HMOs  domiciled  in  Texas,   Nevada  and  California   generally  may  not  pay
extraordinary  dividends without providing the state insurance commissioner with
30 days prior notice,  during which period the  commissioner  may disapprove the
payment.  An  "extraordinary  dividend" is generally defined as a dividend whose
fair market value together with that of other  dividends or  distributions  made
within the  preceding  12 months  exceeds  the greater of (i) ten percent of the
insurer's  surplus  as of the  preceding  December  31 or (ii) the net gain from
operations  of such  insurer for the  12-month  period  ending on the  preceding
December  31.  The  Company is not in a position  to assess  the  likelihood  of
obtaining  future  approval  for the  payment of  "extraordinary  dividends"  or
dividends  other  than  those  specifically  allowed  by  law  in  each  of  its
subsidiaries'  states of domicile.  No prediction  can be made as to whether any
legislative  proposals  relating to dividend rules in the domiciliary  states of
the Company's  subsidiaries  will be made or adopted in the future,  whether the
insurance departments of such states will impose either additional  restrictions
in the  future  or a  prohibition  on the  ability  of the  Company's  regulated
subsidiaries  to  declare  and pay  dividends  or as to the  effect  of any such
proposals or restrictions on the Company's regulated subsidiaries.

The Company is subject to the Federal  HMO Act and the  regulations  promulgated
thereunder.  Of the Company's  three  subsidiary  HMOs, only MedOne Health Plan,
acquired at the end of 1996, is not federally-qualified  under this Act. In 
order to obtain federal  qualification,  an HMO must, among other things,  
provide its members certain services on a fixed, prepaid fee basis and set its 
premium rates
in accordance  with certain  rating  principles  established  by federal law and
regulation.  The HMO must also have  quality  assurance  programs  in place with
respect  to its health  care  providers.  Furthermore,  an HMO may not refuse to
enroll an employee, in most circumstances,  because of such person's health, and
may not expel or refuse to re-enroll  individual members because of their health
or their need for health services.

Under the "corporate  practice of medicine" doctrine,  in most states,  business
organizations,  other  than  those  authorized  to do so,  are  prohibited  from
providing, or holding themselves out as providers of, medical care. Some states,
including  Nevada,  exempt HMOs from this  doctrine.  The laws  relating to this
doctrine  are  subject to numerous  conflicting  interpretations.  Although  the
Company seeks to structure its operations

                                                        14

<PAGE>



to comply with  corporate  practice  of medicine  laws in all states in which it
operates,  there can be no  assurance  that,  given the  varying  and  uncertain
interpretations  of those laws,  the Company  would be found to be in compliance
with  those  laws in all  states.  A  determination  that the  Company is not in
compliance with applicable  corporate  practice of medicine laws in any state in
which it operates could have a material adverse effect on the Company if it were
unable to restructure its operations to comply with the laws of that state.

Medicare and Medicaid  antifraud and abuse  provisions are codified at 42 U.S.C.
Sections  1320a-7(b)  (the  "Anti-kickback  Statute")  and  1395nn  (the  "Stark
Amendments").  Many states have similar  anti-kickback and  anti-referral  laws.
These statutes prohibit certain business  practices and relationships  involving
the  referral of  patients  for the  provision  of health care items or services
under  certain  circumstances.  Sanctions for  violations  of the  Anti-kickback
Statute and the Stark Amendments include criminal penalties and civil sanctions,
including fines and possible  exclusion from the Medicare and Medicaid programs.
Similar  penalties  are  provided  for  violation  of  state  anti-kickback  and
anti-referral  laws.  The  Department of Health and Human  Services  ("HHS") has
issued regulations  establishing "safe harbors" with respect to the Antikickback
Statute.  The Office of the  Inspector  General  recently  proposed new rules to
clarify those safe harbors.  HHS has also recently proposed to establish certain
safe harbors under the Stark Amendments.  The Company believes that its business
arrangements and operations are in compliance with the Antikickback  Statute and
the Stark  Amendments and the  exceptions  set forth therein,  regardless of the
availability  of  regulatory  safe  harbor  protection  with  respect  to  those
statutes.  There can,  however,  be no assurance that (i)  government  officials
charged with  responsibility  for enforcing the prohibitions of the Antikickback
Statute  and the Stark  Amendments  will not assert  that the Company or certain
transactions  in which it is involved are in violation  of those  statutes;  and
(ii) such statutes  will  ultimately  be  interpreted  by the courts in a manner
consistent with the Company's interpretation.

In 1997,  Congress  passed the  Balanced  Budget Act ("Act")  which  revised the
structure  of and  reimbursement  for private  health plan  options for Medicare
enrollees.  The Act seeks to expand the options available to Medicare  enrollees
by  permitting  HCFA to contract  with a variety of types of managed care plans,
creating  a new  Medicare  fee-for-service  option and  establishing  a Medicare
Medical Savings Account  Demonstration  Program. The legislation also encourages
provider  sponsored  organizations  to  contract  directly  with HCFA to provide
coverage for Medicare enrollees.  Federal reimbursement was modified so that the
premiums  paid by HCFA will be adjusted to take into  account,  on an increasing
basis, a blend of national and local health care cost factors,  rather than only
local  costs--starting  with a 10%  national  factor in 1998 and moving to a 50%
national  factor by 2003.  Congress  also  provided  for  gradual  removal  of a
graduate medical education factor in determining reimbursement.  As a result, it
is likely that  premiums  paid by HCFA will not match the rate of  increase  for
medical costs.

The  legislation  includes a provision for a minimum  increase of 2% annually in
health plan Medicare reimbursement for the next five years. The legislation also
provides for  expedited  licensure  of  provider-sponsored  Medicare  plans and 
a repeal  in 1999 of the  rule  requiring  health  plans  to have  one 
 commercial
enrollee for each  Medicare or Medicaid  enrollee.  These changes could have the
effect of increasing  competition  in the Medicare  market.  Further,  effective
January 1, 1999, the Company was required to implement new Medicare  regulations
including,  but not  limited to,  regulations  relating  to  discharge  notices,
additional  provider  contract  language and extensive  new quality  improvement
programs.   These  new   regulations  are  likely  to  increase  the  burden  of
administering  the  Company's  Medicare  plans  and  may  adversely  impact  the
Company's operations.

The  Health  Insurance   Portability  and   Accountability   Act  of  1996  (the
"Accountability  Act") was passed by Congress  and signed into law by  President
Clinton on August  21,  1996 and  effective  beginning  July 1, 1997.  While the
Accountability  Act contains  provisions  regarding  health  insurance or health
plans, such as portability and limitations on pre-existing condition exclusions,
guaranteed  availability and renewability,  it also contains several  anti-fraud
measures that significantly change health care fraud and abuse

                                                        15

provisions.  Some of the  provisions  include (i) creation of an anti-fraud  and
abuse trust fund and  coordination of fraud and abuse efforts by federal,  state
and local authorities;  (ii) extension of the criminal  anti-kickback statues to
all federal health  programs;  (iii)  expansion of and increase in the amount of
civil  monetary   penalties  and  establishment  of  a  knowledge  standard  for
individuals or entities  potentially  subject to civil monetary  penalties;  and
(iv) revisions to current sanctions for fraud and abuse, including mandatory and
permissive exclusion from participation in the Medicare or Medicaid programs.

Workers'  Compensation.   The  Company  is  subject  to  extensive  governmental
regulation  and  supervision  in  each  state  in  which  it  conducts  workers'
compensation business. The primary purpose of such regulation and supervision is
to provide  safeguards for policyholders and injured workers rather than protect
the interests of  shareholders.  The extent and form of the regulation may vary,
but generally has its source in statutes that establish  regulatory agencies and
delegate  to  the  regulatory   agencies  broad   regulatory,   supervisory  and
administrative authority. Typically, state regulations extend to such matters as
licensing companies; restricting the types or quality of investments;  requiring
triennial  financial  examinations  and  market  conduct  surveys  of  insurance
companies; licensing agents; regulating aspects of a company's relationship with
its agents;  restricting use of some  underwriting  criteria;  regulating rates,
forms and  advertising;  limiting the grounds for  cancellation or nonrenewal of
policies,  solicitation  and  replacement  practices;  and specifying what might
constitute unfair practices.  Moreover,  the payment of dividends and the making
of other  distributions  to the Company by its workers'  compensation  insurance
company  subsidiaries are contingent upon the earnings of those subsidiaries and
are subject to various business considerations,  applicable state corporate laws
and  regulations,  the terms of  agreements to which they may become a party and
government  regulations,  which restrict in certain circumstances the payment of
dividends and distributions, and the transfer of assets to the Company.

In the normal  course of business,  the Company and the various  state  agencies
that regulate the activities of the Company may disagree on  interpretations  of
laws and  regulations,  policy wording and  disclosures or other related issues.
These disagreements, if left unresolved, could result in administrative hearings
and/or  litigation.  The  Company  attempts  to  resolve  all  issues  with  the
regulatory agencies,  but is willing to litigate issues where it believes it has
a strong position.  The ultimate outcome of these  disagreements could result in
sanctions and/or  penalties and fines assessed  against the Company.  Currently,
there are no litigation matters pending with any department of insurance.

Typically,  states mandate  participation  in insurance  guaranty  associations,
which  assess   solvent   insurance   companies  in  order  to  fund  claims  of
policyholders of insolvent insurance companies. Under this arrangement, insurers
can be  assessed  up to 1% (or 2% in certain  states) of  premiums  written  for
workers' compensation insurance in that state each year to pay losses and LAE on
covered  claims of insolvent  insurers.  In California and certain other states,
insurance  companies are allowed to recoup such assessments  from  policyholders
while several states allow an offset against premium taxes. Potential assessment
expenses,  net of  recoupment,  if any, for  insolvencies  are not accrued until
after an  insolvency  has occurred  since the  likelihood  and the amount of the
assessment expense cannot be reasonably determined or estimated.  In California,
there have been no new assessments for insolvent workers' compensation insurance
companies since 1990.

California's  Insurance Holding Company Act regulates the payment of shareholder
dividends by insurance companies.  To date, the workers' compensation  insurance
subsidiaries have not paid dividends to the Company.

General.  Besides  state  insurance  laws,  the  Company  is  subject to general
business and  corporation  laws,  federal and state  securities  laws,  consumer
protection  laws,  fair  credit  reporting  acts and other laws  regulating  the
conduct and operation of its subsidiaries.

Employees

The Company had  approximately  4,700 employees as of December 31, 1998. None of
these employees are covered by a collective  bargaining  agreement.  The Company
believes that its relations with its employees are good.


ITEM 2. PROPERTIES

The Company owns several administrative  facilities in southern Nevada totalling
approximately  406,000  square  feet.  Such  facilities  include an  approximate
134,000  square foot six-story  home office  building and an approximate  43,000
square foot two-story corporate administrative headquarters. These buildings are
subject to liens  securing an $800,000  loan balance from Bank of America.  Also
included  in this  total  is a  198,000  square  foot  six-story  administrative
headquarters  building  which became fully  occupied in 1998.  This building was
financed in January  1998 and is subject to a $13.4  million loan  balance.  The
Company  also owns  several  clinical  facilities  in the  southern  Nevada area
totalling  approximately  396,000 square feet and  consisting  primarily of nine
medical clinics and two surgery centers.  The Company leases  additional  office
and clinical space in Nevada totalling  approximately  145,000 and 86,000 square
feet, respectively.

In conjunction with the Kaiser-Texas  acquisition,  the Company  purchased eight
medical   facilities   totalling   approximately   323,000   square   feet   and
administrative  facilities  totalling  approximately  175,000 square feet. These
buildings  are subject to a deed of trust note securing a $35.2 million note. In
addition,  the Company  leases  additional  office and  clinical  space in Texas
totalling approximately 54,000 square feet and 77,000 square feet, respectively.
The above properties are utilized primarily for the managed care operations. The
workers'  compensation  subsidiary  is  headquartered  in  Nevada  and  occupies
approximately 25% of the 198,000 square foot administrative  building as well as
leases  approximately  67,000  square feet of office  space in  California.  The
Company  leases  approximately  150,000  square  feet of  office  space in other
various  states as needed for other  regional  operations,  for TRICARE  service
centers and for the military subsidiary's administrative headquarters.

The Company  believes that current and planned  clinical  space will be adequate
for its present needs.  Additional  clinical space may be required,  however, if
membership continues to expand in southern Nevada.

The Company owns real estate and a building in Park City, Utah purchased in 1996
to provide  entertainment and a meeting  environment for significant current and
prospective  clients,  brokers and others who assist in the Company's  marketing
efforts.

ITEM 3.   LEGAL PROCEEDINGS

The Company is subject to various  claims and other  litigation  in the ordinary
course of business.  Such  litigation  includes  claims of medical  malpractice,
claims for coverage or payment for medical services  rendered to HMO members and
claims by providers  for payment for medical  services  rendered to HMO members.
Also included in such litigation are claims for workers' compensation and claims
by providers for payment for medical services  rendered to injured workers.  The
litigation with Humana  resulting from its acquisition of Physician  Corporation
of America  that was  discussed  in previous  filings has been  settled.  In the
opinion of the Company's  management,  the ultimate  resolution of pending legal
proceedings should not have a material adverse effect on the Company's financial
condition.

</TABLE>

On February 26, 1999, the closing sale price of the common stock was $14 3/8 per
share.

Note:    The  above  stock  prices  have  been   adjusted  to  account  for  the
         three-for-two stock split of the Company's common stock to stockholders
         of record as of May 18, 1998.

Holders

The number of record holders of Common Stock at February 26, 1999 was 254. Based
upon  information  available  to it,  the  Company  believes  there are  several
thousand beneficial holders of the Common Stock.

Dividends

No cash  dividends  have  been paid on the  Common  Stock  since  the  Company's
inception.  The Company  currently intends to retain its earnings for use in its
business and does not anticipate  paying any cash  dividends in the  foreseeable
future.  As a holding  company,  the  Company's  ability to  declare  and to pay
dividends is dependent upon cash distributions from its operating  subsidiaries.
The  ability  of the  Company's  health  maintenance  organization  ("HMO")  and
insurance  subsidiaries  to  declare  and to pay  dividends  is limited by state
regulations applicable to the maintenance of minimum deposits,  reserves and net
worth.  (See  Management's  Discussion  and Analysis of Financial  Condition and
Results of Operations -- Liquidity and Capital  Resources.)  The  declaration of
any  future  dividends  will be at the  discretion  of the  Company's  Board  of
Directors  and will  depend  on,  among  other  things,  future  earnings,  debt
covenants,  operations,  capital requirements and the financial condition of the
Company and upon general business conditions.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

The following  discussion and analysis  provides  information  which  management
believes  is relevant  for an  assessment  and  understanding  of the  Company's
consolidated  financial  condition  and results of  operations.  The  discussion
should be read in conjunction  with the  Consolidated  Financial  Statements and
Related  Notes  thereto.  Any  forward-looking  information  contained  in  this
Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations and any other sections of this 1998 Annual Report on Form 10-K should
be considered in connection with certain cautionary  statements contained in the
Company's  Current Report on Form 8-K filing dated March 17, 1999,  incorporated
herein by reference.  Such cautionary  statements are made pursuant to the "safe
harbor" provisions of the Private  Securities  Litigation Reform Act of 1995 and
identify important risk factors that could cause the Company's actual results to
differ   materially  from  those  expressed  in  any  projected,   estimated  or
forward-looking statements relating to the Company.

Acquisitions

On October 31, 1998,  Sierra and one of its  subsidiaries,  Texas Health Choice,
L.C.  (formerly HMO Texas L.C.)  completed the  acquisition of certain assets of
Kaiser  Foundation  Health  Plan of  Texas  ("Kaiser-  Texas"),  a  health  plan
operating in Dallas/Ft. Worth with approximately 109,000 members, and Permanente
Medical Association of Texas ("Permanente"),  a medical group with approximately
150 physicians. The purchase price was $124 million, which is net $20 million in
operating  cost support to be paid to Sierra by Kaiser  Foundation  Hospitals in
five  quarterly  installments  following  the  closing of the  transaction.  The
purchase price allocation  includes a premium  deficiency reserve of $25 million
for  estimated  losses on the  contracts  acquired  from  Kaiser-Texas.  Of this
amount,  $6.8  million  was  reversed in 1998 to offset  losses on the  acquired
contracts. The purchase price includes amounts for real estate and eight medical
and office facilities with approximately  500,000 square feet. In December 1998,
certain  accreditation goals were met by the health plan resulting in a purchase
price increase of $3.0 million to $127 million.  The purchase price may increase
up to an  additional  $27 million over three years if certain  growth and member
retention goals are met by the health plan.  Sierra assumed no prior liabilities
for malpractice or other litigation, or for any unanticipated future adjustments
to claims  expenses for periods prior to closing.  The  transaction was financed
with a five-year  revolving  credit facility and a $35.2 million note payable to
Kaiser Foundation Health Plan of Texas. The note is secured by the acquired real
estate. Approximately $110 million of the $200 million revolving credit facility
was used to fund the transaction.

On December 31, 1998, Sierra completed the acquisition of the Nevada health care
business of Exclusive  Healthcare,  Inc., United of Omaha Life Insurance Company
and United World Life Insurance Company, all of which are subsidiaries of Mutual
of Omaha Insurance  Company.  The purchase price is contingent based on how many
members are  retained  through  2000 and 2001.  No cash will be paid until group
renewals   begin  in  2000.   Sierra   retained   approximately   9,000  members
(approximately 4,400 HMO members) subsequent to the acquisition.

In August 1997,  the Company  acquired the assets and  operations  of Total Home
Care, Inc. ("THC") for  approximately  $3.1 million,  net of cash acquired.  THC
provides home infusion, oxygen, and durable medical equipment services in Nevada
and Arizona.  The Company sold the Arizona  operations  in the first  quarter of
1998 for  approximately  $1.5 million.  Also, in the first quarter of 1998,  the
Company  purchased three medical  clinics in southern  Nevada for  approximately
$7.3 million.

Effective  December  31,  1996,  the  Company  purchased  Prime  Holdings,  Inc.
("Prime") for  approximately  $32.2 million in cash. At December 31, 1996, Prime
operated MedOne Health Plan,  Inc., a 12,800 member HMO, and also served 215,000
people through preferred provider organizations, workers' compensation programs,
and  administrative  services  products  for  self-insured  employers  and union
welfare funds, primarily in the state of Nevada.

Overview

The Company derives revenues from its health maintenance organizations,  managed
indemnity,  military  health care services and workers'  compensation  insurance
subsidiaries.  To a lesser extent, the Company also derives additional specialty
product  revenues from non-HMO and insurance  products  (consisting  of fees for
workers'  compensation  administration,   utilization  management  services  and
ancillary  products),  professional  fees  (consisting  primarily  of  fees  for
providing  health care services to non-members and co-payment fees received from
members),  and investment and other revenue.  Medical premium revenues accounted
for  approximately  58.8%,  71.2% and 67.3% of the Company's  total revenues for
1998,  1997 and 1996,  respectively.  The  decrease  in  medical  premiums  as a
percentage  of total  revenues  is  primarily  due to the  addition  of military
contract  revenues.  Continued  medical  premium  revenue  growth is principally
dependent  upon  continued   enrollment  in  the  Company's  products  and  upon
competitive and regulatory factors.

The Company's principal expenses consist of medical expenses,  military contract
expense,  specialty product expenses, and general,  administrative and marketing
expenses.  Medical  expenses  represent the aggregate  expenses of operating the
Company's  multi-specialty medical group and other provider subsidiaries as well
as capitation  fees and other  fee-for-service  payments  paid to  independently
contracted physicians,  hospitals and other health care providers. As a provider
of managed  care  services,  the  Company  seeks to manage  medical  expenses by
employing  or  contracting  with  physicians,  hospitals  and other  health care
providers at negotiated price levels, by adopting quality assurance programs, by
monitoring and managing  utilization of physicians and hospital  services and by
providing incentives to use cost-effective providers. Military contract expenses
represent  the  expenses of  delivering  health care as agreed to in the TRICARE
contract with the federal government as well as administrative  costs to operate
the  military  health care  subsidiary.  Specialty  product  expenses  primarily
consist  of losses  and loss  adjustment  expenses,  and  underwriting  expenses
associated  with the Company's  workers'  compensation  insurance  subsidiaries.
General,  administrative and marketing expenses generally represent  operational
costs other than those  associated with the delivery of health care services and
specialty product services.

On September  30, 1997,  Sierra  Military  Health  Services,  Inc.  ("SMHS") was
awarded a TRICARE  contract to provide  managed health care coverage to eligible
beneficiaries in Region 1. In June 1998, the Company began providing health care
benefits to approximately 606,000 individuals in Connecticut,  Delaware,  Maine,
Maryland,  Massachusetts,  New Hampshire,  New Jersey,  New York,  Pennsylvania,
Rhode Island, Vermont,

                                                        21

<PAGE>



Virginia,  West Virginia and  Washington,  D.C. In 1998, the award resulted in a
total  of  $204.8   million  of  revenue  for  the  final   five-months  of  the
implementation phase and seven months of health care delivery. SMHS was notified
on February 13, 1998 that the United States  General  Accounting  Office ("GAO")
sustained a competitor's  protest of the contract award for TRICARE Managed Care
Support Region 1 and recommended that the contract be re-bid.  In December 1998,
the  Company  reached  an  agreement  to  settle  the  protest.  As  part of the
settlement,  the  competitor  will  forego  any and all  rights  it may  have to
challenge  the  contract  award  and seek a re-bid  (See Note 14 of Notes to the
Consolidated Financial Statements).

Integration,  settlement and other expenses represent  identifiable  incremental
costs the Company has incurred  primarily in  connection  with various  mergers,
acquisitions  and planned  dispositions as well as expenses  associated with the
Company's  proposal to serve TRICARE  beneficiaries in Region 1 and the ultimate
cost to settle a bid protest.  Start-up expenses associated with the proposal to
serve TRICARE  beneficiaries  were charged to operations  upon  notification  of
award.

1998 Compared to 1997

Revenues.   The  Company's   total   operating   revenues  for  1998   increased
approximately  43.7% to $1.04 billion from $721.7 million for 1997. The increase
was primarily due to military contract revenue of $204.8 million and an increase
in premium revenue of $95.5 million.  The military  contract revenue is a result
of the  implementation of the TRICARE contract as well as the first seven months
of health care delivery. Revenue under the TRICARE contract is recorded based on
the contract  price as agreed to by the federal  government.  The contract  also
contains  provisions which adjust the contract price based on actual experience.
The estimated effects of these adjustments are recognized on a monthly basis.

Medical premium revenue from the Company's HMO and managed  indemnity  insurance
subsidiaries  increased  $95.5  million,  or 18.6%.  Excluding the effect of the
Kaiser-Texas  acquisition  in  the  fourth  quarter  of  1998,  premium  revenue
increased $66.9 million, or 13.0%. The $66.9 million increase in premium revenue
reflects a 3.4%  increase  in member  months  (the number of months of each year
that an individual  is enrolled in a plan).  Medicare  member  months  increased
20.1% which contributed to the increase in medical premium revenue.  Such growth
in Medicare member months  contributes  significantly to the increase in premium
revenues as the  Medicare per member  premium  rates are over three times higher
than the average  commercial premium rate. The Company's premium rates increased
an  average of 3% to 4% for its HMO  commercial  groups and in excess of 10% for
managed indemnity commercial groups. The Company also realized a slight increase
in its  capitation  rate  established  by Health Care  Financing  Administration
("HCFA").  Approximately  78% of  the  Company's  Nevada  Medicare  members  are
enrolled in the Social HMO Medicare program.  HCFA is considering  adjusting the
reimbursement  factor  for  the  Social  HMO  members  in  the  future.  If  the
reimbursement  for these members  decreases  significantly  and related  benefit
changes are not made  timely,  there could be a material  adverse  effect on the
Company's business.

Specialty  product revenue  increased $2.2 million,  or 1.5%, for the year ended
December  31, 1998  compared to the prior year.  The increase was due to revenue
growth of $5.1 million in the workers'  compensation  insurance operation offset
in part by a  decrease  in  administrative  services  and other  revenue of $2.9
million due primarily to the termination of the Company's workers'  compensation
administrative  services  contract  with the  State  of  Nevada.  The  Company's
workers'  compensation  subsidiary  signed a  reinsurance  agreement  whereby  a
greater portion of premium is ceded thus reducing revenue. The agreement results
in a reduction of specialty  product expense as discussed later in this section.
Excluding the effect of the new reinsurance agreement, the workers' compensation
subsidiaries'  revenue would have increased $21.2 million  compared to the prior
year.  Professional fee revenue increased  approximately $14.1 million primarily
due to the January 1998  acquisition of the operations of two medical clinics in
southern  Nevada and the clinics  acquired  in the  Dallas/Ft.  Worth  area.  In
addition approximately $3.5 million of the increase in professional fees was due
to the operations of Total Home Care, Inc.  ("THC") which was acquired in August
1997.

Investment  and other  revenue  increased  approximately  $3.2  million over the
comparable  period in the prior year  primarily  due to an  increase in invested
balances and capital gains realized on the sale of investments.

Medical and  Specialty  Product  Expense.  Medical  expenses as a percentage  of
medical  premiums and  professional  fees ("Medical Care Ratio")  increased from
76.9% to 78.4%  for the year  ended  December  31,  1998  compared  to the prior
period.  The  increase  in the  medical  care  ratio was due to an  increase  in
Medicare members as a percentage of fully-insured  members,  continued expansion
in Texas,  northern  Nevada and Arizona  which have higher  medical care ratios,
higher  pharmacy costs and the  acquisitions  of THC and two medical clinics for
which  costs  of  operations  are  included  in  medical  expenses.  The cost of
providing  medical  care  to  Medicare  members  generally  requires  a  greater
percentage of the premiums received.  Pharmacy costs increased as the management
of the pharmacy  benefit was  transitioned  from a capitated  pharmacy  benefits
contract to in-house management in the third quarter of 1998. The costs

                                                        23

<PAGE>



under  such  capitation   contract  were   substantially   below  actual  claims
experience.  The medical care ratio is expected to further  increase in 1999 due
to the changes in member mix and pharmacy costs noted above. Included in medical
expenses is the reversal of $4.4 million of premium  deficiency reserve that was
used to offset losses on contracts from the  Kaiser-Texas  operations  that were
acquired on October 31, 1998.

Specialty product expenses decreased  approximately $800,000, or less than 1.0%,
due primarily to the  implementation  of the reinsurance  agreement as discussed
previously.  Specialty  product revenue and expense is primarily  related to the
workers'  compensation  insurance business.  Effective January 1, 1998, workers'
compensation  claims  are  reinsured  between  $500,000  and  $100  million  per
occurrence.  For claims  occurring  on and after  July 1,  1998,  that are below
$500,000, the Company obtained quota share and excess of loss reinsurance. Under
this  agreement,  the Company  reinsures 30% of the first $10,000 of each claim,
75% of the next $40,000 and 100% of the next  $450,000.  The Company  receives a
ceding  commission  from the reinsurer as a partial  reimbursement  of operating
expenses.  Excluding the effect of the reinsurance agreement,  specialty product
expense would have increased $19.5 million compared to the prior year.

The combined ratio for the workers'  compensation  insurance  business was 98.7%
compared to 101.9% for the comparable  prior year period.  The reduction was due
to a 198 basis point  decrease in the loss ratio and a 122 basis point  decrease
in the expense ratio.  The decrease in the loss ratio was largely due to the new
reinsurance  agreement  for losses  occurring on and after July 1, 1998 and as a
result of the Company's ability to overlay and implement managed care techniques
to the workers'  compensation claims. The combined ratio excluding the effect of
the new  reinsurance  agreement was 101.6% for the year ended December 31, 1998.
In addition,  favorable  loss  development on prior accident years totalled $9.6
million for the year ended  December 31, 1998,  compared to net  favorable  loss
development of $9.0 million for the comparable prior year period.  The favorable
loss  development  is largely due to actual paid  losses  being below  projected
losses. There can be no assurance that favorable  development,  or the magnitude
thereof,  will  continue in the future.  The  reduction in the expense ratio was
largely  due to a  reduction  in  agents'  commissions,  as a result of a ceding
commission related to the new reinsurance  agreement and from lower salaries and
related benefits expenses.  The losses and loss adjustment expense ratio for the
year ended  December 31, 1998 reflect the  Company's  current  projection of the
ultimate  costs of claims  occurring  in the  current as well as prior  accident
years.  Such projections are subject to change and any change would be reflected
in the income  statement.  Workers'  compensation  claims are paid over  several
years. Until payment is made, the Company invests the monies, earning a yield on
the invested balance.

Military Contract  Expense.  The military contract expense is comprised of those
expenses incurred in 1998 for five months of contract  implementation  and seven
months of health care  delivery.  This  expense  consists  primarily of costs to
provide  managed  health care services to eligible  beneficiaries  in accordance
with the Company's  TRICARE contract.  Under the contract,  SMHS provides health
care  services to  approximately  606,000  dependents  of active  duty  military
personnel  and military  retirees  and their  dependents  through  subcontractor
partnerships  and  individual  providers.  Health care costs are recorded in the
period when services are provided to eligible beneficiaries, including estimates
for  provider  costs which have been  incurred  but not reported to the Company.
Also,  included  in  military  contract  expense  are costs  incurred to perform
specific  administrative  services,  such as health care appointment scheduling,
enrollment,  network management and health care advice line services,  and other
administrative functions of the military health care subsidiary.

General,  Administrative  and Marketing  Expenses.  General,  administrative and
marketing ("G&A") cost increased $16.8 million, or 17.9%, compared to 1997. As a
percentage of revenues,  G&A costs for 1998 decreased to 10.7% from 13.0% during
1997. The decrease in the G&A ratio is primarily due to the addition of military
contract revenues offset in part by costs for additional  infrastructure  needed
to  support  overall  Company  growth.  Excluding  military  revenues,  G&A as a
percentage of revenues was 13.3% in 1998. Of the $16.8 million  increase in G&A,
$3.2 million was due to  additional  G&A related to the acquired HMO business in
the Dallas/Ft.  Worth area. The remaining increase of $13.6 million consisted of
$3.8

                                                        24

million  increased  compensation  expense,  resulting  primarily from additional
employees  supporting expanded services and new benefit programs for management.
Broker,   third  party   administration   and  premium  tax  expense   increased
approximately  $900,000 due to increased membership.  In addition,  depreciation
expense increased $1.7 million.

Integration,  Settlement  and Other Costs.  In the fourth  quarter of 1998,  the
Company expensed  approximately $13.9 million, $10.3 million after tax, of costs
primarily  associated  with the  settlement  of the  protest  pertaining  to its
military  services  contract as well as costs associated with the integration of
the  Kaiser-Texas  business  acquired  October  31,  1998  (see  Note  14 to the
Consolidated Financial Statements).

On March 18, 1997, the Company  announced it had terminated its merger agreement
with  Physician  Corporation  of America,  Inc. and  recorded  expenses of $11.0
million,  $8.4 million after tax, for merger-  related  costs.  During the third
quarter  of  1997  SMHS  was  awarded  a  contract  to  serve  TRICARE  eligible
beneficiaries in Region 1. Development expenses of $18.4 million,  $10.6 million
net of  taxes,  were  recorded  in the  third  quarter  primarily  for  expenses
associated with the Company's  proposal to serve TRICARE Region 1. Such expenses
had been deferred until award notification.

Interest Expense and Other.  Interest expense and other increased  approximately
$2.7 million for the year ended  December 31, 1998,  compared to the same period
in the prior  year due to an  increase  in debt as a result of the  Kaiser-Texas
acquisition.

Income Taxes. For the period, the Company recorded  approximately  $13.8 million
of tax expense  for an  effective  tax rate of 25.8%  compared to 23.9% in 1997,
excluding  the tax effects of  identifiable  integration,  settlement  and other
costs.  The  Company's  current low  operating tax rate is primarily a result of
tax-preferred investments and the change in the deferred tax valuation 
allowance,
which is due  primarily  to the ability to use a portion of net  operating  loss
carryovers. The effective tax rate will increase to the 32% to 34% range in 1999
as most of the valuation  allowances for net operating loss  carryforwards  have
been utilized as of December 31, 1998.

1997 Compared to 1996

Revenues.  The Company's  total  operating  revenues for 1997 increased 25.4% to
$721.7  million from $575.4  million for 1996. The increase was primarily due to
medical premium revenue  increases of  approximately  $126.9 million,  or 32.8%,
from the  Company's  HMO and  managed  indemnity  insurance  subsidiaries.  Such
premium growth resulted principally from an approximate 30.3% increase in member
months.  The Company's HMO and insurance  subsidiaries'  premium rates increased
approximately 2.5%,  primarily due to an increase in its capitation rate for its
Medicare  members as  established  by HCFA.  The increase was due in part to the
Company's participation in HCFA's social HMO program. The Company realized 1% to
3% rate increases for its existing HMO  subsidiaries'  commercial groups and the
managed indemnity  subsidiary.  However,  these increases were offset in part by
lower premium rates at MedOne Health Plan, an HMO acquired on December 31, 1996.
The Company's  specialty  product revenue  increased $12.9 million,  or 9.7%, to
$146.2  million in 1997 from $133.3  million in 1996.  The  increase  was due to
specialty product revenue growth in the workers'  compensation  insurance market
of  approximately  $8.3 million and an increase in  administrative  services and
other of $4.6 million due primarily to the acquisition of Prime Health, Inc., at
the end of 1996.  Some of this increase will be offset in the future by the loss
of a portion  of the state of  Nevada's  self-insured  medical  business.  Also,
effective  September 30, 1997, the Company terminated its workers'  compensation
administrative  services contract with the state of Nevada.  The contract served
approximately  200,000  enrollees  and  provided  approximately  $3.2 million in
revenues for the year ended  December 31, 1997.  The contract was  terminated to
allow the Company to participate in the Nevada workers'  compensation  insurance
market when the state  allows  private  insurance  companies  to begin  offering
products,  which is  anticipated  for 1999.  Professional  fees  increased  $2.4
million,  or 8.3%,  over 1996 to $31.2 million.  This increase is due in part to
the acquisition of the

                                                        25

assets and operations of THC during the third quarter of 1997. THC provides home
infusion,  oxygen and durable medical equipment  services in Nevada and Arizona.
During the fourth quarter of 1997, SMHS began the  implementation  period of its
TRICARE  contract.  The military contract revenue of $4.3 million is a result of
this contract. Investment and other revenue was consistent with the prior year.

Medical and Specialty  Product  Expenses.  Total medical  expenses  increased by
$103.4 million in 1997 compared to 1996.  This 32.7% increase  resulted from the
consolidated  member month growth discussed  previously.  The Medical Care Ratio
increased  from 76.0% to 76.9% due  primarily to member  growth and expansion in
areas with  higher  medical  expenses,  such as  northern  Nevada and Texas.  In
addition,  MedOne  Health Plan has a higher  Medical Care Ratio,  which  further
contributed  to the  increase  in the  Company's  overall  Medical  Care  Ratio.
Specialty  product  expenses  increased $12.3 million,  or 9.4%, over 1996. This
increase is due  primarily  to the  increase in workers'  compensation  premiums
noted above.  Specialty  product revenue and expense is primarily related to the
workers' compensation insurance business.

The combined ratio for the workers'  compensation  insurance business was 101.9%
for the year ended  December  31,  1997,  compared to 103.2% for the  comparable
prior year period.  The  reduction  was due to a 40 basis point  decrease in the
loss ratio along with a 90 basis point decrease in the expense  ratio.  Compared
to the prior year period,  incurred  losses for the current  accident  year were
reduced as a result of the Company's  ability to overlay and  implement  managed
care techniques to the workers'  compensation  claims. In addition,  the Company
had net favorable loss development on prior accident years totaling $9.0 million
compared to net favorable  loss  development of $15.3 million for the comparable
prior year  period.  The  favorable  development  is largely  due to actual paid
losses  being  below  projected  losses.  The  majority  of the  favorable  loss
development  occurred on the 1992 through 1995 accident  years.  There can be no
assurances that favorable  development,  or the magnitude thereof, will continue
in the future.  The losses and loss adjustment  expense ratio for the year ended
December 31, 1997  reflects the  Company's  current  projection  of the ultimate
costs of claims  occurring in the current as well as prior accident years.  Such
projections  are  subject  to change and any change  would be  reflected  in the
income  statement.  Workers'  compensation  claims are paid over several  years.
Until payment is made,  the Company  invests the monies,  earning a yield on the
invested balance.

General,  Administrative  and  Marketing  Expenses.  G&A costs  increased  $21.7
million, or 30.0%, for the twelve months ended December 31, 1997 compared to the
twelve months ended  December 31, 1996.  As a percentage of revenues,  G&A costs
for the twelve  months  ended  December  31, 1997  increased to 13.0% from 12.6%
during the comparable period in 1996. Of the $21.7 million increase in G&A, $8.6
million was in compensation costs primarily resulting from additional  employees
supporting  expanded  services and increased  incentive  amounts for management.
Broker,   third-party   administration,   and  premium  tax  expenses  increased
approximately  $8.5  million  due  to  increased  membership.  Amortization  and
depreciation  costs increased  approximately  $1.9 million  primarily due to the
amortization of goodwill resulting from the Prime acquisition. The remaining G&A
increase  was  due to  additional  expenses  in  several  areas  including  data
processing maintenance.

     Military  Contract  Expense.  During the fourth quarter of 1997, SMHS began
the implementation period of its TRICARE contract. The military contract expense
is a result of this contract.

Integration,  Settlement  and  Other  Costs.  On March  18,  1997,  the  Company
announced it had terminated its merger  agreement with Physician  Corporation of
America,  Inc. and recorded and paid expenses of  approximately  $11.0  million,
$8.4 million after tax, for merger-related costs.

During  the third  quarter  of 1997,  SMHS,  a wholly  owned  subsidiary  of the
Company,  was  awarded a contract to serve  TRICARE  eligible  beneficiaries  in
Region 1. This region includes approximately 606,000 TRICARE beneficiaries in 13
northeastern states and the District of Columbia. Development expenses of

                                                        26

<PAGE>



$18.4  million,  $10.6 million net of taxes,  were recorded in the third quarter
primarily for expenses  associated with the Company's proposal to serve eligible
beneficiaries in Region 1.

During 1995, as part of the Company's clinical expansion and growth efforts, the
Company acquired a medical facility in Mohave County, Arizona, across the border
from Laughlin,  Nevada. This medical facility included a 12-bed hospital. During
1996,  the Company  implemented  a plan to exit the  hospital  business  and has
actively pursued buyers for this business. As a result of this plan, the Company
recorded  a charge of $3.8  million,  ($2.9  million  after  tax) in the  fourth
quarter of 1996,  primarily to recognize the  estimated  costs to dispose of the
hospital.  As of  December  31,  1998,  the  Company has been unable to reach an
agreement to sell the hospital.

As a result of higher than expected claim and  administrative  costs relative to
premium rates that can be obtained in certain regional insurance  operations and
the  Company's  inability to negotiate  adequate  provider  contracts due to its
limited  presence  in some of  these  markets,  the  Company  adopted  a plan to
restructure  certain  insurance  operations during the third quarter of 1996 and
recorded a charge of $8.3 million, ($6.2 million after tax). These restructuring
costs included cancellation of certain contractual  obligations of $6.0 million,
lease  termination  costs of $1.5  million and  approximately  $750,000 of other
costs.

Interest Expense and Other.  Interest expense and other increased  approximately
$1.6 million over the prior year  primarily due to the $2.1 million  benefit for
minority  interests  recorded  in  1996,  offset  in  part  by  an  increase  in
capitalized  interest  related  to various  construction  projects  in 1997.  In
November 1996, the Company acquired  complete  ownership of a Texas HMO in which
it had previously held a 50% interest. That HMO began business in March 1995 and
experienced  losses in both years.  In the prior year, a portion of these losses
resulted in a benefit from minority interests.

Income Taxes.  The Company's  effective tax rate for the year ended December 31,
1997 was 11.8%,  compared to 25.2% in 1996. The difference between the Company's
effective  tax rate and the current  federal tax rate is due primarily to a $4.7
million tax benefit  recorded as a result of a  reduction  of the  deferred  tax
valuation  allowance and the Company's  portfolio of tax preferred  investments.
These benefits are more  significant  as a result of the charges  related to the
Physicians Corporation of America acquisition and start-up costs associated with
the TRICARE contract.  Excluding these costs, the effective tax rate for 1997 is
23.9%. See Note 9 of Notes to Consolidated Financial Statements.

LIQUIDITY AND CAPITAL RESOURCES

The Company's  cash flow from  operating  activities of $50.1 million during the
twelve months ended  December 31, 1998 resulted  primarily from $39.6 million of
net income,  $19.3 million in depreciation  and amortization and $6.4 million in
provision for doubtful accounts offset by a $15.2 million decrease in cash flows
from changes in assets and liabilities. The decrease in cash flow resulting from
the  change in assets  and  liabilities  was  primarily  due to an  increase  in
reinsurance  recoverable  and  military  accounts  receivable.  The  increase in
reinsurance  recoverable  is  primarily  due to the  new  reinsurance  agreement
implemented  by  the  Company's  workers'  compensation  subsidiary  for  claims
occurring  on or after July 1, 1998 that are below  $500,000  (see Note 6 to the
Consolidated Financial  Statements).  Military accounts receivable increased due
to the  implementation  of  health  care  delivery  in 1998.  Military  accounts
receivable   consists  primarily  of  one  month's  contract  payment  from  the
government in arrears,  estimates of bid price  adjustments  ("BPAs")  under the
contract  based on  actual  experience  and any  change  orders  not  originally
specified in the contract.  These cash outflows were offset in part by increases
in military health care payable and other current  liabilities.  The increase in
military health care payable is a result of health care delivery  beginning June
1, 1998 for the Region 1 TRICARE contract. Military health care payable includes
the  estimated  cost for unpaid  claims for which health care services have been
provided to TRICARE  eligibles and a provision of the estimated costs for claims
that have been incurred but have not been

                                                        27

<PAGE>



reported. The increase in other current liabilities is primarily due to expenses
related to  operations  of the  military  services  subsidiary  and  reinsurance
premiums payable due to the new reinsurance contract.

SMHS receives  monthly cash payments  equivalent  to  one-twelfth  of its annual
contractual price with the Department of Defense ("DOD") and accrues health care
revenue on a monthly  basis for any monies owed above its monthly  cash  receipt
based on the number of at-risk eligible beneficiaries. Approximately $34 million
of the military  accounts  receivable  balance is associated with monies owed to
SMHS as a result of providing  health care  services for a larger than  expected
beneficiary population. SMHS expects to receive this amount at the completion of
the first BPA. The BPA process  serves to adjust the DOD's  monthly  payments to
SMHS,  because  such  payments  are  based  in part on 1996 DOD  estimates  for:
beneficiary  population,  beneficiary  population  baseline  health  care  cost,
inflation and military direct care system utilization.  As actual information is
made  available  for the above items,  quarterly  adjustments  are made to SMHS'
monthly  health  care  payment in  addition  to a lump sum  adjustment  for past
months.  SMHS  accrues  for  such  adjustments  on a  monthly  basis  as  actual
information  is made  available.  The  first  such  adjustment  did not occur as
scheduled on February 28, 1999 (SMHS anticipates  additional DOD delays of up to
6 months). If the timing or amount of the BPA reimbursement varies significantly
from the Company's expectations, there could be a material adverse effect on the
Company's business and cash flows.

Net cash used for investing  activities  during 1998  included  $40.7 million in
capital  expenditures for construction  costs associated with office facilities,
furniture  and  equipment  for the newly  constructed  six-story  administrative
headquarters building,  continued  implementation of three new computer systems,
computer and medical  equipment,  other  capital  needs to support the Company's
growth,  and  a  $24.2  million  net  increase  in  investments.   In  addition,
approximately  $111.4  million of cash was used to purchase  the  Dallas,  Texas
operations of Kaiser Foundation Health Plan.

Cash flows from  financing  activities  included  net  proceeds  from  long-term
borrowings  (proceeds  less  payments)  of $113.1  million.  The majority of net
proceeds  from  long-term   borrowings   was  used  to  fund  the   Kaiser-Texas
acquisition.  The  transaction  was financed with a five-year  revolving  credit
facility. As of December 31, 1998, the Company had $139 million in borrowings on
the $200 million line of credit.  Interest under the credit facility is variable
and  based  on the  London  Interbank  Offering  Rate  ("LIBOR")  plus a  margin
determined  by reference  to the  Company's  leverage  ratio.  In addition,  $50
million of the outstanding  balance is covered by interest-rate swap agreements.
The average cost of  borrowing on this line of credit for the fourth  quarter of
1998,  including the impact of the swap agreements,  was approximately 8.0%. The
terms of the credit facility contain a mandatory payment schedule that begins on
June 30, 2001 and ends on September  30, 2003 if the principal  balance  exceeds
certain  thresholds.  The terms of the credit facility contain certain covenants
including a minimum fixed charge  coverage ratio and a maximum  leverage  ratio.
The remaining $61 million available balance on the line of credit as of December
31, 1998, may be used for general corporate purposes, including working capital.

During  1998  and  1997,  the  Company  used  $9.2  million  and  $5.5  million,
respectively, to buy back Company stock on the open market.

In the second  quarter of 1997,  the Company's  Board of Directors  authorized a
$3.0 million line of credit from the Company to the  Company's  Chief  Executive
Officer ("CEO").  The CEO borrowed a total of $650,000 in 1998 and $2 million in
1997 at an interest rate equal to the LIBOR  Offering Rate plus 53 basis points.
During the first quarter of 1999, the CEO repaid  approximately  $360,000 of the
line of  credit.  The line of credit is  collateralized  by certain of the CEO's
rights to  compensation  from the  Company  and is due and payable no later than
August 15, 1999.

In  September  1991,  CII  issued  convertible   subordinated   debentures  (the
"Debentures")  due September 15, 2001.  The  Debentures  bear interest at 7 1/2%
which is due semi-annually on March 15 and September 15.

                                                        28

Each $1,000 in  principal is  convertible  into 25.382  shares of the  Company's
common stock at a  conversion  price of $39.40 per share.  Unamortized  issuance
costs of  $500,000  are  included in other  assets on the balance  sheet and are
being  amortized  over the life of the  Debentures.  The  Debentures are general
unsecured  obligations  of CII  only and are not  guaranteed  by  Sierra  Health
Services, Inc. ("Sierra"). During the twelve months ended December 31, 1998, the
Company purchased $3.2 million of the Debentures on the open market.

The  holding   company  may  receive   dividends  from  its  HMO  and  insurance
subsidiaries  which  generally  must be  approved  by  certain  state  insurance
departments.  The Company's HMO and insurance subsidiaries are required by state
regulatory  agencies to maintain certain deposits and must also meet certain net
worth and reserve requirements.  The Company had restricted assets on deposit in
various  states  totaling  $17.8  million as of December 31,  1998.  The HMO and
insurance   subsidiaries   must  also  meet  requirements  to  maintain  minimum
stockholder's  equity,  on a statutory basis,  ranging from $1.1 million to $5.2
million. In addition,  in conjunction with the Kaiser-Texas  acquisition,  Texas
Health  Choice,  L.C.  ("TXHC")  entered into a letter  agreement with the Texas
Department  of  Insurance  whereby  TXHC agreed to maintain a net worth of $20.0
million.  Of the cash and cash  equivalents  held at December  31,  1998,  $81.3
million is designated for use only by the regulated  subsidiaries.  Such amounts
are  available  for transfer to the holding  company from the HMO and  insurance
subsidiaries only to the extent that they can be remitted in accordance with the
terms of existing management agreements and by dividends.  Remaining amounts are
generally available on an unrestricted basis.

The  National  Association  of Insurance  Commissioners  has adopted new minimum
capitalization  requirements for HMOs, health care insurance  entities and other
risk-bearing health care entities. Depending on the nature and extent of the new
minimum  capitalization  requirements  ultimately  adopted by each state,  there
could be an  increase  in the  capital  required  for  certain of the  Company's
regulated subsidiaries.  The Company intends to fund any increase from available
parent company cash reserves;  however, there can be no assurance that such cash
reserves will be sufficient to fund these minimum  capitalization  requirements.
The new requirements are expected to be effective on or before December 31, 1999
upon  enactment  by each  state.  The  Company  does not  believe  that any such
required  increase in the amount of funds to be contributed to the  subsidiaries
will be material.

The holding company will not receive  dividends from its regulated  subsidiaries
if such  dividend  payment  would cause  violation  of  statutory  net worth and
reserve requirements.

The Company has a 1999 capital budget of  approximately  $60 million,  primarily
for  computer   hardware  and  software,   furniture  and  equipment  and  other
requirements  due to the  Company's  computer  system  conversion  and projected
growth and expansion. The Company's liquidity needs over the next 12 months will
primarily be for the capital items noted above,  the Company's stock  repurchase
program,  debt service and  expansion  of the  Company's  operations,  including
potential  acquisitions.  The Company  believes that existing  working  capital,
operating cash flow and, if necessary,  mortgage  financing,  equipment leasing,
and amounts  available  under its credit facility will be sufficient to fund its
capital  expenditures and debt service.  Additionally,  subject to unanticipated
cash  requirements,  the Company  believes that its existing working capital and
operating cash flow and, if necessary, its access to new credit facilities, will
enable it to meet its liquidity needs on a longer term basis.

Year 2000

The Year 2000 issue  exists  because  many  computer  systems  and  applications
currently  use  two-digit  date fields to designate a year.  As the century date
change occurs,  date-sensitive  systems will recognize the year 2000 as 1900, or
not at all.  This  inability to  recognize  or properly  treat the Year 2000 may
cause  systems  to  process  critical  financial  and  operational   information
incorrectly.


                                                        29

The Company is currently  in the process of  modifying or replacing  its mission
critical financial and operational  computer systems. The Company is also in the
process  of  testing  its  non-information   system  technology  for  Year  2000
compliance.  The Year 2000  project has been broken down into five  phases:  (1)
inventorying  Year  2000  items;  (2)  assessing  the Year 2000  items  that are
determined to be material to the Company;  (3) renovating or replacing  material
items  that are  determined  not to be Year  2000  compliant;  (4)  testing  and
validating material items; and (5) implementing renovated and validated systems.

At December 31, 1998,  the inventory  and  assessment  phases are  substantially
complete as it relates to all material  computer systems and  approximately  50%
complete  as it  relates  to  non-information  system  technology.  The  Company
estimates  that the  replacement/renovation  phases  and the  testing/validation
phases will be 95% complete by October 31, 1999.  The Company  estimates that it
is  approximately  50% complete  with the total project as of December 31, 1998.
Contingency  planning for the mission critical business  operations is scheduled
to be  completed  by  April  1999.  These  plans  focus on  business  operations
involving information systems and non-information systems technologies.

The Company has initiated formal  communications with entities with whom it does
business to assess  their Year 2000  issues.  Evaluations  of the most  critical
third  parties  have been  initiated,  and  follow-up  reviews will be conducted
through 1999.  Contingency  plans are being developed based on these evaluations
and are  expected  to be  completed  by the  middle  of  1999.  There  can be no
assurances that the systems of other companies or governmental agencies, such as
HCFA and the Department of Defense ("DOD"),  on which the Company relies will be
timely  modified for Year 2000, or that the failure to modify by another company
would not have a material adverse effect on the Company. Based upon two separate
reports  issued by the United States  General  Accounting  Office it is doubtful
that the  computer  systems  at both  HCFA and the DOD will be fully  Year  2000
compliant by the end of 1999. The Company does not currently have available data
to predict the impact of such non-compliance on its business operations.  Should
there be any material delays caused by Year 2000 issues, the Company anticipates
that the governmental entities will make estimated payments.

The  Company  is in the  process  of  implementing  three  major  systems  at an
estimated cost of $36 million to $38 million,  which includes the implementation
costs  related to the recently  acquired  Kaiser-Texas  operations.  To date the
Company has spent  approximately  $19.0 million on the new computer  systems and
other Year 2000 items. The Company is expensing the costs to make  modifications
to existing computer systems and non-computer  equipment.  Management  currently
estimates the  remaining new computer  system costs and other Year 2000 costs to
be $13.0  million to $16.0  million for  operations  in  existence  prior to the
Kaiser-Texas  transaction and $6.0 million to $8.0 million for the  Kaiser-Texas
operations  that were acquired on October 31, 1998.  While this is a substantial
effort,   it  will  give  the  Company  the  benefits  of  new   technology  and
functionality  for many of its financial and  operational  computer  systems and
applications.

The  failure  to  correct  a  material  Year  2000  problem  could  result in an
interruption  of, or a failure of,  certain  business  activities or operations.
Such  failures  could  materially  adversely  affect the  Company's  operations,
liquidity and financial  condition.  Due to the general uncertainty  inherent in
the Year  2000  problem,  resulting  in part from  uncertainty  of the Year 2000
readiness of third parties with which the Company does business,  the Company is
unable to determine at this time whether the consequences of potential Year 2000
failures  will have a  material  adverse  impact  on the  Company's  results  of
operations, liquidity or financial condition. The Company's Year 2000 project is
expected to  significantly  reduce the Company's level of uncertainty  about the
Year 2000 problem. The Company believes that, with the implementation of the new
computer  systems  and  completion  of the  entire  project  as  scheduled,  the
possibility of significant interruptions of operations should be reduced.

     The  above   contains   forward-looking   statements   including,   without
limitation, statements relating to the Company's plans, strategies,  objectives,
expectations,  intentions, and adequate resources, that are made pursuant to the
"safe harbor"  provisions  of the Private  Securities  Litigation  Reform Act of
1995. Readers

are  cautioned  that  forward-looking  statements  contained  in the  Year  2000
disclosure  should be read in conjunction  with the following  disclosure of the
Company:

The costs of the project  and the dates on which the  Company  plans to complete
the necessary Year 2000  modifications are based on management's best estimates,
which were derived utilizing numerous assumptions of future events including the
continued  availability of certain resources and other factors.  However,  there
can be no guarantee  that these  estimates  will be achieved and actual  results
could differ materially from those plans. Specific factors that might cause such
material  differences include, but are not limited to, the availability and cost
of  personnel  trained in this area,  the  ability  to locate  and  correct  all
relevant  computer codes,  the ability of the Company's  significant  suppliers,
customers  and others with which it  conducts  business,  including  federal and
state governmental  agencies, to identify and resolve their own Year 2000 issues
and similar uncertainties.

Inflation

Health  care costs  continue to rise at a faster  rate than the  Consumer  Price
Index.  The Company uses various  strategies to mitigate the negative effects of
health care cost inflation,  including setting commercial  premiums based on its
anticipated  health care costs,  risk-sharing  arrangements  with the  Company's
various health care providers,  and other health care cost containment measures.
There can be no assurance,  however,  that, in the future, the Company's ability
to  manage  medical  costs  will not be  negatively  impacted  by items  such as
technological advances, competitive pressures, applicable regulations, increases
in pharmacy costs,  utilization  changes and catastrophic items, which could, in
turn, result in medical cost increases equaling or exceeding premium increases.

Government Regulation

The Company's  business,  offering health care coverage,  health care management
services,  workers'  compensation programs and, to a lesser extent, the delivery
of medical services, is heavily regulated at both the federal and state levels.

Government  regulation  of health  care  coverage  products  and  services  is a
changing area of law that varies from  jurisdiction to jurisdiction.  Changes in
applicable  laws  and  regulations   are   continually   being   considered  and
interpretation  of  existing  laws and rules also may change  from time to time.
Regulatory agencies generally have broad discretion in promulgating  regulations
and in interpreting and enforcing laws and regulations.

While the Company is unable to predict what regulatory  changes may occur or the
impact on the Company of any  particular  change,  the Company's  operations and
financial  results could be negatively  affected by  regulatory  revisions.  For
example,  any  proposals  affecting   underwriting   practices,   limiting  rate
increases,  requiring  new  or  additional  benefits  or  affecting  contracting
arrangements  (including proposals to require HMOs and PPOs to accept any health
care providers  willing to abide by an HMO's or PPO's contract terms) may have a
material adverse effect on the Company's business.  The continued  consideration
and enactment of  "anti-managed  care" laws and regulations by federal and state
bodies may make it more  difficult  for the Company to manage  medical costs and
may adversely affect financial results.

In  addition  to changes in  applicable  laws and  regulations,  the  Company is
subject to various audits, investigations and enforcement actions. These include
possible  government actions relating to the federal Employee  Retirement Income
Security Act, which  regulates  insured and  self-insured  health coverage plans
offered by employers,  the Federal  Employees  Health Benefit Plan,  federal and
state fraud and abuse laws, and laws relating to utilization  management and the
delivery of health care. Any such  government  action could result in assessment
of damages, civil or criminal fines or penalties, or other sanctions, including

                                                        31

exclusion from participation in government programs. In addition,  disclosure of
any adverse  investigation or audit results or sanctions could negatively affect
the Company's  reputation in various  markets and make it more difficult for the
Company to sell its products and services.

Recently Issued Accounting Standards

In March 1998,  the  Accounting  Standards  Executive  Committee of the American
Institute of Certified Public Accountants ("AcSEC") issued Statement of Position
98-1 ("SOP 98-1"),  "Accounting for the Costs of Computer Software Developed For
or Obtained For Internal Use". SOP 98-1 requires certain computer software costs
to be capitalized  and amortized over the software's  estimated  useful life. In
June 1998, the AcSEC issued Statement of Position 98-5 ("SOP 98-5"),  "Reporting
on the Costs of Start-Up Activities".  This standard requires organization costs
and costs associated with start-up  activities to be expensed as incurred.  Both
statements  are  effective  for years  beginning  after  December 15, 1998.  The
Company will adopt SOP 98-1 and SOP 98-5 for the fiscal year ending December 31,
1999 and does not believe these  statements  will have a material  impact on its
financial statements.

In June 1998, The Financial  Accounting  Standards Board issued  "Accounting for
Derivative Instruments and Hedging Activities" ("FAS 133"). FAS 133 is effective
for fiscal years beginning after June 15, 1999. FAS 133 addresses the accounting
for derivative  instruments including certain derivative instruments embedded in
other  contracts,  and hedging  activities.  The Company  does not believe  this
statement will have a material impact on its financial statements.

ITEM 7a.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As of December 31, 1998, the Company has approximately  $392 million in cash and
cash equivalents,  and short-term,  long-term and restricted investments. Of the
investments,  approximately  $254.6 million is classified as  available-for-sale
investments  and $54.0 million is classified  as  held-to-maturity  investments.
These  investments are primarily in fixed income,  investment grade  securities.
The Company's  investment  policies  emphasize return of principal and liquidity
and are focused on fixed  returns that limit  volatility  and risk of principal.
Because of the Company's investment policies, the primary market risk associated
with the Company's portfolio is interest rate risk.

Assuming an immediate 10% increase in interest rates, the net hypothetical  loss
in fair value of  shareholders'  equity  related  to  financial  instruments  is
estimated  to  be  approximately   $7.5  million  (after  tax)  (2.5%  of  total
shareholders'  equity).  The Company  believes that such an increase in interest
rates would not have a material impact on future earnings or cash flows as it is
unlikely  that the Company would need or choose to  substantially  liquidate its
investment portfolio.

The effect of interest rate risk on potential  near-term  net income,  cash flow
and fair value was determined based on commonly used sensitivity  analyses.  The
models  project the impact of interest  rate changes on a wide range of factors,
including  duration and  prepayment.  Fair value was estimated  based on the net
present  value of cash flows or duration  estimates,  assuming an immediate  10%
increase in interest rates.

As of  December  31,  1998,  the  Company  had  approximately  $139  million  in
borrowings  outstanding  under a revolving credit facility that was entered into
in October 1998. Interest under the credit facility is variable and based on the
London  Interbank  Offering  Rate plus a margin,  except for $50  million of the
outstanding  balance  that is  covered by  interest-rate  swap  agreements.  The
average cost of borrowing  on this line of credit was  approximately  8% for the
fourth  quarter  of  1998.  If the  average  cost  of  borrowing  on the  amount
outstanding  as of December  31,  1998,  was to increase by 10%,  annual  income
before tax would decrease by approximately $900,000.

             MANAGEMENT REPORT ON CONSOLIDATED FINANCIAL STATEMENTS


The management of Sierra Health Services, Inc., is responsible for the integrity
and  objectivity of the  accompanying  Consolidated  Financial  Statements.  The
statements have been prepared in conformity with generally  accepted  accounting
principles  applied on a consistent  basis and are not misstated due to fraud or
material  error.  The  statements  include  some amounts that are based upon the
Company's best estimates and judgment.

The  accounting  systems and  controls  of the  Company are  designed to provide
reasonable   assurance  that   transactions  are  executed  in  accordance  with
management's  authorization,   that  the  financial  records  are  reliable  for
preparing  financial  statements and maintaining  accountability for assets, and
that assets are safeguarded against losses from unauthorized use or disposition.
Management  believes that for the year ended December 31, 1998, such systems and
controls were adequate to meet the objectives discussed herein.

The  accompanying   Consolidated  Financial  Statements  have  been  audited  by
independent  certified  public  accountants,  whose audits  thereof were made in
accordance with generally  accepted auditing  standards and included a review of
internal  accounting controls to the extent necessary to design audit procedures
aimed at gathering  sufficient  evidence to provide a reasonable basis for their
opinion on the fairness of presentation of the Consolidated Financial Statements
taken as a whole.

The Audit  Committee of the Board of  Directors,  comprised  solely of directors
from outside the Company,  meets  regularly with  management and the independent
auditors to review the work  procedures of each. The  independent  auditors have
free access to the Audit Committee, without management being present, to discuss
the  results of their  opinions  on the  adequacy  of the  Company's  accounting
controls  and the quality of the  Company's  financial  reporting.  The Board of
Directors,  upon  the  recommendation  of  the  Audit  Committee,  appoints  the
independent auditors, subject to stockholder ratification.

                          INDEPENDENT AUDITORS' REPORT


Board of Directors
Sierra Health Services, Inc.:

We have audited the  accompanying  consolidated  balance sheets of Sierra Health
Services,  Inc., and its  subsidiaries as of December 31, 1998 and 1997, and the
related consolidated  statements of operations,  stockholders'  equity, and cash
flows for each of the three years in the period ended  December  31,  1998.  Our
audits also included the financial  statement  schedules  listed in the index at
Item 14 (a)(2). These financial statements and financial statement schedules are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements and financial statement schedules based
on our audits.

We  conducted  our  audits  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 Sierra Health Services,  Inc. and
its  subsidiaries  at  December  31,  1998 and 1997,  and the  results  of their
operations  and their cash flows for each of the three years in the period ended
December 31, 1998 in conformity with generally accepted  accounting  principles.
Also, in our opinion,  such financial  statement  schedules  when  considered in
relation  to the  basic  consolidated  financial  statements  taken  as a whole,
present fairly in all material respects the information set forth therein.

                  SIERRA HEALTH SERVICES, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
              For the Years Ended December 31, 1998, 1997 and 1996


1.   BUSINESS

Business.  The consolidated  financial statements include the accounts of Sierra
Health Services, Inc. ("Sierra") and its subsidiaries  (collectively referred to
as the  "Company").  The  Company is a managed  health  care  organization  that
provides and administers the delivery of comprehensive  health care and workers'
compensation programs with an emphasis on quality care and cost management.  The
Company's  broad range of managed  health care services is provided  through its
health maintenance organizations ("HMOs"),  managed indemnity plans, third-party
administrative  services  programs for  employer-funded  health  benefit  plans,
workers'  compensation  medical  management  programs  and its  military  health
services programs. Ancillary products and services that complement the Company's
managed health care product lines are also offered.

Acquisitions.  On October 31, 1998, Texas Health Choice, L.C. ("TXHC") (formerly
HMO Texas,  L.C.), a subsidiary of Sierra,  completed the acquisition of certain
assets of Kaiser Foundation Health Plan of Texas ("Kaiser-Texas"), a health plan
operating in Dallas/Ft. Worth with approximately 109,000 members, and Permanente
Medical  Association  of Texas  ("Permanente"),  a 150  physician  medical group
operating in that area. The purchase price was $124 million, which is net of $20
million in  operating  cost  support  to be paid to Sierra by Kaiser  Foundation
Hospitals  in  five  quarterly   installments   following  the  closing  of  the
transaction. The purchase price allocation includes a premium deficiency reserve
of approximately $25 million for estimated losses on the contracts acquired from
Kaiser-Texas.  The  purchase  price  includes  amounts for real estate and eight
medical and office facilities  encompassing  approximately  500,000 square feet.
During the first  quarter of 1999  certain  accreditation  goals were met by the
health plan  resulting in a purchase  price  increase of $3.0  million,  to $127
million.  The purchase  price may increase an additional  $27 million over three
years if certain growth and member retention goals are met by the health plan.

The  acquisition  has been recorded using purchase  accounting and the excess of
the  purchase  price over the fair value of the assets  acquired was recorded as
goodwill. The goodwill, in the amount of $102.0 million, is being amortized on a
straight line basis over 40 years.

The following pro forma information  (unaudited) has been prepared assuming that
this acquisition had taken place at the beginning of the respective periods. The
pro forma  information  includes  adjustments  for the  amortization of goodwill
arising from the transaction and interest  expense that would have been incurred
to finance the purchase.  The pro forma financial information is not necessarily
indicative of the results of operations had the transaction been effected on the
assumed dates. <TABLE>

On December 31, 1998, Sierra completed the acquisition of the Nevada health care
business of Exclusive  Healthcare,  Inc., United of Omaha Life Insurance Company
and United World Life Insurance Company, all of which are subsidiaries of Mutual
of Omaha Insurance  Company.  The purchase price is contingent based on how many
members are  retained  through  2000 and 2001.  No cash will be paid until group
renewals   begin  in  2000.   Sierra   retained   approximately   9,000  members
(approximately 4,400 HMO members) subsequent to the acquisition.

In August 1997,  the Company  acquired the assets and  operations  of Total Home
Care, Inc. ("THC") for  approximately  $3.1 million,  net of cash acquired.  THC
provides home infusion, oxygen, and durable medical equipment services in Nevada
and Arizona. The Company sold the Arizona operations in the first

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
              For the Years Ended December 31, 1998, 1997 and 1996


quarter of 1998 for  approximately  $1.5 million.  Also, in the first quarter of
1998,  the  Company  purchased  three  medical  clinics in  southern  Nevada for
approximately $7.3 million.

Effective  December  31,  1996  the  Company  purchased  Prime  Holdings,   Inc.
("Prime"),  for  approximately  $32 million in cash.  At December 31, 1996 Prime
operated  MedOne Health Plan, Inc.  ("MedOne"),  a 12,800 member HMO. Prime also
served  215,000  people  through  preferred  provider  organizations,   workers'
compensation  programs and  administrative  service  products  for  self-insured
employers and union welfare trust funds,  primarily in the state of Nevada.  The
acquisition resulted in goodwill of $31 million.

In  November  1996,  the  Company  acquired  complete   ownership  of  TXHC  for
$5,040,000.  The  Company  had  previously  held a 50  percent  interest  in the
Houston-based health plan. The purchase resulted in goodwill of $5,040,000.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of  Consolidation.  All  significant  intercompany  transactions  and
balances  have been  eliminated.  Sierra's  wholly owned  subsidiaries  include:
Health Plan of Nevada, Inc. ("HPN"),  TXHC and MedOne, all licensed HMOs; Sierra
Health and Life Insurance  Company,  Inc.  ("SHL"),  a health and life insurance
company;  Southwest Medical Associates,  Inc. ("SMA"),  and The Medical Group of
Texas ("TMGT"),  multi-specialty medical groups; CII Financial,  Inc. ("CII"), a
holding company  primarily  engaged in writing workers'  compensation  insurance
through its wholly owned  subsidiaries;  Sierra Military Health Services,  Inc.,
("SMHS"),  a company that has been contracted to provide and administer  managed
care services to certain TRICARE eligible beneficiaries from June 1, 1998 to May
31,  2003;  administrative  services  companies;  a home health care  agency;  a
hospice;  a home medical  products  subsidiary;  and a company that provides and
manages mental health and substance abuse services.

Medical Premiums.  Non-Medicare member enrollment is represented  principally by
employer  groups.  Medical  premiums  are  billed  to  each  employer  group  in
accordance  with  negotiated  contracts,  and such premium revenue is recognized
when earned.  Unearned premium revenue includes  payments under prepaid Medicare
contracts  with the Health Care  Financing  Administration  ("HCFA") and prepaid
HPN, TXHC and MedOne commercial and SHL indemnity premiums. HPN and TXHC offer a
prepaid health care program to Medicare  recipients.  Revenues  associated  with
these Medicare  recipients were  approximately  $238,913,000,  $186,105,000  and
$140,611,000 in 1998, 1997 and 1996, respectively.

Specialty  Product  Revenues.  These  revenues  consist  primarily  of  workers'
compensation premiums.  Premiums are calculated by formula such that the premium
written  is  earned  pro rata  over the term of the  policy.  Also  included  in
specialty  product revenues are  administrative  services and certain  ancillary
product  revenues.  Such  revenues  are  recognized  in the  period in which the
service is  performed  or the period that  coverage  for  services is  provided.
Premiums  written in excess of  premiums  earned  are  recorded  as an  unearned
premium  revenue  liability.  Premiums earned include an estimate for earned but
unbilled  premiums.  Also  included in  specialty  product  revenue are revenues
associated with administrative services and certain ancillary products.

Military Contract Revenues. Revenue under the TRICARE contract is recorded based
on the contract price as agreed to by the federal government.  The contract also
contains  provisions which adjust the contract price based on actual experience.
The estimated effects of these adjustments are recognized on a monthly basis. In
addition,  the Company  records revenue based on estimates of the earned portion
of any contract change orders not originally specified in the contract.

                  SIERRA HEALTH SERVICES, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
              For the Years Ended December 31, 1998, 1997 and 1996


Professional Fees. Revenue for professional  medical services is recorded on the
accrual basis in the period in which the services are provided.  Such revenue is
recorded at established  rates net of provisions for estimated  contractual  and
charitable allowances.

Medical  Expenses.  Sierra  contracts  with  hospitals,   physicians  and  other
providers  of  health  care  under   capitated  or  discounted   fee-for-service
arrangements  including  hospital per diems to provide  medical care services to
enrollees. Capitated providers are at risk for the cost of medical care services
provided to the Company's enrollees in the relevant  geographic areas;  however,
the  Company is  ultimately  responsible  for the  provision  of services to its
enrollees  should the  capitated  provider be unable to provide  the  contracted
services.  Health  care costs are  recorded  in the  period  when  services  are
provided to enrolled members,  including estimates for provider costs which have
been  incurred as of the  balance  sheet date but not  reported to the  Company.
Losses on specific contracts, if any, are accrued when measurable.

Specialty Product Expenses.  This expense consists  primarily of losses and loss
adjustment  expense ("LAE") and policy  acquisition costs associated with issued
workers' compensation policies. Losses and LAE is based upon the accumulation of
cost  estimates for reported  claims  occurring  during the period as well as an
estimate for losses that have  occurred but have not yet been  reported.  Policy
acquisition costs consist of commissions,  premium taxes and other  underwriting
costs,  which are directly  related to the  production  and retention of new and
renewal  business  and are deferred  and  amortized as the related  premiums are
earned.  Should it be  determined  that future  policy  revenues and earnings on
invested funds relating to existing insurance  contracts will not be adequate to
cover related costs and expenses,  deferred costs are expensed. Also included in
specialty product expense are costs associated with administrative  services and
certain ancillary products. These costs are recorded when incurred.

Military Contract Expenses.  This expense consists primarily of costs to provide
managed health care services to eligible  beneficiaries  in accordance  with the
Company's  TRICARE  contract.  Under the  contract,  SMHS  provides  health care
services to approximately  606,000  dependents of active duty military personnel
and military retirees and their dependents  through  subcontractor  partnerships
and  individual  providers.  Health  care costs are  recorded in the period when
services are provided to eligible beneficiaries including estimates for provider
costs which have been  incurred as of the balance sheet date but not reported to
the Company.  Also included in military  contract  expense are costs incurred to
perform  specific  administrative  services,  such as  health  care  appointment
scheduling, enrollment, network management and health care advice line services,
and other administrative functions of the military health care subsidiary.

Cash and Cash  Equivalents.  The Company  considers cash and cash equivalents as
all highly liquid instruments with a maturity of three months or less at time of
purchase.  The carrying amount of cash and cash  equivalents  approximates  fair
value because of the short maturity of these instruments.

     Investments.  Short- and long-term  investments consist principally of U.S.
Government  securities  and municipal  bonds,  as well as corporate and mortgage
backed securities.  Short-term  investments have maturities of one year or less.
Long-term investments have maturities in excess of one year.

Restricted  Cash and  Investments.  Certain  subsidiaries  are required by state
regulatory  agencies to maintain certain deposits and must also meet certain net
worth  and  reserve  requirements.  The  Company  and  its  subsidiaries  are in
compliance with the applicable minimum regulatory and capital requirements.

Military Accounts Receivable.  Amounts receivable under government contracts are
comprised  primarily  of one month's  contract  payment from the  government  in
arrears, estimates of adjustments under the contract based on actual experience,
and  estimates  of the  earned  portion  of any  change  orders  not  originally
specified in the contract.

                  SIERRA HEALTH SERVICES, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
              For the Years Ended December 31, 1998, 1997 and 1996


Property and Equipment.  Property and equipment are stated at cost.  Maintenance
and repairs that do not improve or extend the life of the respective  assets are
charged to  operations.  Depreciation  and  amortization  is computed  using the
straight-line  method over the estimated service lives of the assets or terms of
leases if shorter. Estimated useful lives are as follows:

               Buildings and Improvements                     30 years
               Leasehold Improvements                         3 - 10 years
               Furniture, Fixtures and Equipment              3 - 5 years
               Data Processing Hardware and Software          3 - 5 years

Goodwill.  Goodwill has been recorded  primarily as a result of various business
acquisitions  by the Company.  Amortization is provided on a straight line basis
over periods not exceeding 40 years. The Company evaluates the carrying value of
its intangible assets at each balance sheet date.

Medical Claims Payable and Military Health Care Payable.  Medical claims payable
and Military  health care payable  include the estimated  cost for unpaid claims
for which  health care  services  have been  provided to  enrollees  and TRICARE
eligibles  and a  provision  of the  estimated  costs for claims  that have been
incurred but have not been reported.

Reserve for Losses and Loss Adjustment  Expense.  The reserve for losses and LAE
consists of estimated  costs of each unpaid claim  reported to the Company prior
to the close of the  accounting  period,  as well as those  incurred but not yet
reported.  The methods for  establishing  and  reviewing  such  liabilities  are
continually reviewed and adjustments are reflected in current operations.

Income Taxes. The Company accounts for income taxes using the liability  method.
Deferred  income tax assets and  liabilities  result from temporary  differences
between the tax basis of assets and liabilities and the reported  amounts in the
consolidated  financial  statements  that will  result in taxable or  deductible
amounts in future years. The Company's  temporary  differences arise principally
from certain net operating losses, accrued expenses, reserves and depreciation.

Concentration  of Credit Risk.  The  Company's  financial  instruments  that are
exposed to credit risk consist primarily of investments and accounts receivable.
The  Company  maintains  cash and cash  equivalents,  and short-  and  long-term
investments with various financial  institutions.  These financial  institutions
are located in many different  regions,  and company policy is designed to limit
exposure with any one institution.

Credit risk with respect to accounts receivable is generally  diversified due to
the large number of entities  comprising the Company's customer base, other than
gaming, and their dispersion across many different  industries.  These customers
are  primarily  located  in the  states  in which  the  Company  operates.  Such
operations are principally in California, Nevada and Texas. However, the Company
is licensed and does  business in several  other states as well.  As of December
31, 1998, the Company has receivables  outstanding  from the federal  government
related to its TRICARE contract in the amount of $69.6 million. The Company also
has receivables from certain  reinsurers.  Reinsurance  contracts do not relieve
the Company  from its  obligations  to enrollees  or  policyholders.  Failure of
reinsurers to honor their obligations could result in losses to the Company. The
Company  evaluates  the  financial  condition of its  reinsurers to minimize its
exposure to significant losses from reinsurer insolvencies.  All reinsurers that
the Company has  reinsurance  contracts  with are rated A- or better by the A.M.
Best Company.

Recently Issued Accounting  Standards.  In March 1998, the Accounting  Standards
Executive  Committee of the American  Institute of Certified Public  Accountants
("AcSEC")  issued  Statement of Position 98-1 ("SOP 98-1"),  "Accounting for the
Costs of Computer Software Developed For or Obtained For Internal Use". SOP 98-1
requires  certain  computer  software costs to be capitalized and amortized over
the software's  estimated  useful life. In June 1998, the AcSEC issued Statement
of Position 98-5 ("SOP 98-5"),  "Reporting on the Costs of Start-Up Activities".
This standard requires organization costs and costs

associated with start-up activities to be expensed as incurred.  Both statements
are  effective for years  beginning  after  December 15, 1998.  The Company will
adopt SOP 98-1 and SOP 98-5 for the fiscal  year  ending  December  31, 1999 and
does not believe these  statements  will have a material impact on its financial
statements.

In June 1998, The Financial  Accounting  Standards Board issued  "Accounting for
Derivative Instruments and Hedging Activities" ("FAS 133"). FAS 133 is effective
for fiscal years beginning after June 15, 1999. FAS 133 addresses the accounting
for derivative  instruments including certain derivative instruments embedded in
other  contracts,  and hedging  activities.  The Company  does not believe  this
statement will have a material impact on its financial statements.

Estimates and Assumptions. The preparation of 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 disclosure of contingent  assets and liabilities at the date of
the  financial  statements  and the  reported  amounts of revenues  and expenses
during the reporting  period.  Estimates and  assumptions  include,  but are not
limited to,  medical and  specialty  product  expenses and military  revenue and
expenses. Actual results may materially differ from estimates.

Stock Split. On May 5, 1998, the Company announced a three-for-two  stock split.
Each  stockholder of record of the Company owning one share of common stock, par
value of $.005,  as of the close of business on the record date of May 18, 1998,
received  an  additional  one-half  share  on  June  18,  1998.  In  lieu of any
fractional  share resulting from the stock split, a stockholder  received a cash
payment based on the closing  price of the Company's  common stock on the record
date. The par value remains $.005 per share. Common stock and earnings per share
amounts have been retroactively adjusted to account for the split.

Company's common stock at a conversion price of $39.40 per share. The Debentures

anti-dilutive.

Of  the  cash  and  cash  equivalents  that  total  $83,910,000  million  in the
accompanying  Consolidated  Balance  Sheet at  December  31,  1998,  $81,328,000
million is limited for use only by the Company's  regulated  subsidiaries.  Such
amounts are  available  for transfer to Sierra from the  regulated  subsidiaries
only to the  extent  that  they can be  remitted  in  accordance  with  terms of
existing  management  agreements  and by  dividends  which  customarily  must be
approved by regulating state insurance  departments.  The remainder is available
to Sierra on an unrestricted basis.

6.   REINSURANCE

In the normal course of business,  the Company seeks to reduce  potential losses
that may arise from  catastrophic  events  that cause  unfavorable  underwriting
results by reinsuring certain levels of such risk with other reinsurers. Amounts
recoverable from reinsurers are estimated in a manner  consistent with the claim
liability associated with the reinsurance policy.

The  Company  is covered  under  medical  reinsurance  agreements  that  provide
coverage  for 50% - 90% of hospital  and other costs in excess of,  depending on
the contract,  $100,000 to $200,000, per case, up to a maximum of $2,000,000 per
member per  lifetime for both the managed  indemnity  and HMO  subsidiaries.  In
addition,  certain  of the  Company's  HMO  members  are  covered  by an  excess
catastrophe reinsurance contract. Reinsurance premiums of $2,860,000, $3,156,000
and  $3,235,000  net of  reinsurance  recoveries of  $1,185,000,  $1,729,000 and
$2,276,000   are  included  in  medical   expense  for  1998,   1997  and  1996,
respectively.  In addition, SHL maintains reinsurance on certain other insurance
products.

CII also has reinsurance treaties in effect. Effective January 1, 1998, workers'
compensation  claims  between  $500,000  and  $100,000,000  per  occurrence  are
reinsured.  In 1997 and 1996, workers'  compensation claims between $350,000 and
$60,000,000 per occurrence were reinsured. In addition,  effective July 1, 1998,
workers'  compensation  claims below $500,000 per occurrence are reinsured under
quota  share  and  excess  reinsurance  agreements  (referred  to as "low  level
reinsurance") with an A+ rated carrier. Under this agreement,  CII reinsures 30%
of the first $10,000 of each loss, 75% of the next $40,000

                                                        48

     and 100% of the next $450,000.  CII receives a ceding  commission  from the
reinsurer as a partial reimbursement of its operating expenses.

The low level  reinsurance  agreement  contains both retroactive and prospective
reinsurance coverage and CII has bifurcated the low level reinsurance  agreement
to account  for the  different  accounting  treatments.  The amount by which the
estimated ceded liabilities exceed the amount paid for the retroactive  coverage
is amortized to income over the estimated remaining  settlement period using the
interest method.  For the year ended December 31, 1998, CII amortized a deferred
gain of $1,038,000. Any subsequent changes in estimated or actual cash flows are
accounted for by adjusting the previously  recorded deferred gain to the balance
that would have existed had the revised estimate been available at the inception
of the  reinsurance  transactions,  with a  corresponding  charge  or  credit to
income.

At  December  31, 1998 and 1997,  the amount of  reinsurance  recoverable  under
prospective reinsurance contracts for unpaid losses and loss adjustment expenses
for CII was $37,797,000 and $21,056,000, respectively. At December 31, 1998, the
amount of reinsurance recoverable under the retroactive reinsurance contract was
$18,710,000.  The  amount of  reinsurance  receivable  for paid  losses and loss
adjustment expenses was $1,917,000 and $358,000,  at December 31, 1998 and 1997,
respectively.

Reinsurance  contracts  do not  relieve  the  Company  from its  obligations  to
enrollees or  policyholders.  Failure of reinsurers  to honor their  obligations
could  result in losses to the  Company.  The Company  evaluates  the  financial
condition of its reinsurers to minimize its exposure to significant  losses from
reinsurer  insolvencies.   All  reinsurers  that  the  Company  has  reinsurance
contracts with are rated A- or better by the A.M. Best company.

Revolving Credit  Facility.  On October 31, 1998, the Company replaced its prior
line of credit  with a $200  million  credit  facility  under  which it has $139
million in borrowings  outstanding  as of December 31, 1998.  Interest under the
credit facility is variable and based on the London Interbank Offering Rate plus
a margin  determined  by  reference  to the  Company's  leverage  ratio.  Of the
outstanding balance,  $50.0 million is covered by interest-rate swap agreements.
The average cost of  borrowing on this line of credit for the fourth  quarter of
1998,  including the impact of the swap agreements,  was approximately 8.0%. The
terms of the credit facility contain a mandatory payment schedule that begins on
June 30, 2001 and ends on September  30, 2003 if the principal  balance  exceeds
certain thresholds. The terms of the credit facility

At December 31, 1998, the Company had  approximately  $20,022,000 of regular tax
net  operating  loss  carryforwards  which  are  limited  to use at the  rate of
approximately  $7,021,000  per year  during  the  carryforward  period.  The net
operating loss  carryforwards  can be used to reduce future taxable income until
they  expire  through  the year 2011.  In  addition  to the net  operating  loss
carryforwards,  the Company has alternative minimum tax credits of approximately
$848,000  which can be used to reduce  regular tax  liabilities in future years.
There is no  expiration  date  for the  alternative  minimum  tax  credits.  The
majority  of the above items are  subject to both  annual and  separate  company
limitations required by the Internal Revenue Code.

A valuation  allowance has been set up to reflect the Company's inability to use
tax benefits from certain acquisitions  currently or in the near future. For the
years  ended  December  31,  1998 and 1997,  the  Company  was able to realize a
portion of the tax benefits for which a valuation  allowance had been previously
established.  As a result,  the  Company  reduced  its  valuation  allowance  by
$4,691,000  and  $4,663,000  for the years  ended  December  31,  1998 and 1997,
respectively.

10.  COMMITMENTS AND CONTINGENCIES

Leases. The Company is the lessee under several operating leases,  most of which
relate to office  facilities  and  equipment.  The  rentals on these  leases are
charged to expense  over the lease term as the  Company  becomes  obligated  for
payment and, where  applicable,  provide for rent  escalations  based on certain
costs and price index  factors.  The  following is a schedule,  by year,  of the
future minimum lease payments under existing operating leases: <TABLE>

</TABLE>

Rent expense  totaled  $8,763,000,  $5,827,000 and $4,945,000 in 1998,  1997 and
1996, respectively.

Litigation and Legal Matters. The Company is subject to various claims and other
litigation in the ordinary course of business.  Such litigation  includes claims
of medical  malpractice,  claims for  coverage or payment  for medical  services
rendered to HMO members and claims by providers for payment for medical services
rendered  to HMO  members.  Also  included  in such  litigation  are  claims for
workers'  compensation  and claims by providers for payment for medical services
rendered to injured  workers.  In the opinion of the Company's  management,  the
ultimate  resolution  of pending  legal  proceedings  should not have a material
adverse effect on the Company's financial condition.

11.       EMPLOYEE BENEFIT PLANS

Defined  Contribution Plan. The Company has a defined  contribution  pension and
401(k) plan (the "Plan") for its  employees.  The Plan covers all  employees who
meet certain age and length of service  requirements.  The Company contributes a
maximum  of  2%  of  eligible  employees'  compensation  and  matches  50%  of a
participant's  elective  deferral up to a maximum of either 10% of an employee's
compensation or the maximum  allowable under current IRS statute.  Expense under
the plan totaled  $4,522,000,  $3,929,000 and $3,216,000 in 1998, 1997 and 1996,
respectively.

Supplemental Retirement Plan. The Company has Supplemental Retirement Plans (the
"SRPs") for certain officers,  directors and highly compensated  employees.  The
SRPs are non-qualified  deferred  compensation  plans through which participants
may elect to  postpone  the  receipt  and  taxation of all or a portion of their
salary and bonuses  received  from the Company.  The Company also matches 50% of
those  contributions  that  participants are restricted from deferring,  if any,
under the Company's pension and 401(k) plan. As contracted with the Company, the
participants or their  designated  beneficiaries  may begin to receive  benefits
under the SRPs upon participant death,  disability,  retirement,  termination of
employment or certain other circumstances including financial hardship.

Executive Life Insurance Plan. Effective July 1, 1997 the Company has funded and
entered into split dollar life insurance  agreements  with certain  officers and
key  executives  (selected and approved by the Sierra Board of  Directors).  The
premiums paid by the Company will be reimbursed  upon the  occurrence of certain
events as specified in the contract.

     Supplemental Executive Retirement Plan (SERP).  Effective July 1, 1997, the
Company  adopted  a  defined  benefit   retirement  plan  covering  certain  key
employees. The Company is funding the benefits through the

purchase of certain life insurance policies.  Benefits are based on, among other
things,  the  employee's  average  earnings over the  five-year  period prior to
retirement  or  termination,  and length of service.  Benefits  attributable  to
service  prior to the  adoption  of the plan are  amortized  over the  estimated
remaining service period for those employees participating in the plan. In 1998,
the Company expanded the SERP to include more participants. The effect of adding
these participants is included in plan amendments in the reconciliation below.

A reconciliation of ending year balances is as follows:

12.       CAPITAL STOCK PLANS

Stockholders'  Rights Plan.  Each share of Sierra common stock,  par value $.005
per share,  contains one right (a "Right").  Each Right  entitles the registered
holder to purchase from Sierra a unit consisting of one one-hundredth of a share
of the Series A Junior Participating Preferred Shares (a "Unit"), par value $.01
per share,  of Sierra,  or a combination  of securities and assets of equivalent
value,  at a purchase  price of $100.00  per Unit,  subject to  adjustment.  The
Rights have certain  anti-takeover  effects.  The Rights will cause  substantial
dilution  to a person or group  that  attempts  to  acquire  Sierra on terms not
approved by Sierra's Board of Directors, except pursuant to an offer conditioned
on a  substantial  number  of Rights  being  acquired.  The  Rights  should  not
interfere with any merger or other business combination approved by the Board of
Directors  since  Sierra  may  redeem  the Rights at the price of $.02 per Right
prior to the time that a person or group has  acquired  beneficial  ownership of
20% or more of Sierra common stock.

Stock  Option  Plans.   The  Company  has  several  plans  that  provide  common
stock-based awards to employees and to non-employee directors. The plans provide
for the granting of Options,  Stock, and other  stock-based  awards.  Awards are
granted by a  committee  appointed  by the Board of  Directors.  Options  become
exercisable at such times and in such installments as set by the committee.  The
exercise price of each option equals the market price of the Company's  stock on
the date of grant. Stock options generally vest at a rate of 20% - 25% per year.
Options generally expire one year after the end of the vesting period.

The following table reflects the activity of the stock option plans:

Employee  Stock  Purchase  Plan. The Company has an employee stock purchase plan
(the  "Purchase  Plan")  whereby  employees may purchase  newly issued shares of
stock through payroll  deductions at 85% of the fair market value of such shares
on specified dates as defined in the Purchase Plan. As of December 31, 1998, the
Company had 353,000 shares reserved for purchase under the Purchase Plan. During
1998,  a total of 144,000  shares were  purchased at prices of $17.75 and $19.06
per share. During January 1999, 72,000 shares were issued to employees at $17.85
per share in connection with the Purchase Plan.

Accounting for  Stock-Based  Compensation.  The Company uses the intrinsic value
method in accounting for its stock-based  compensation  plans.  Accordingly,  no
compensation  cost has been  recognized  for its employee stock option plans nor
the Stock  Purchase Plan. Had  compensation  cost for the Company's  stock-based
compensation  plans been  determined  based on the fair value at the grant dates
for awards under those plans,  the  Company's  net income and earnings per share
would have been reduced to the pro forma amounts indicated below: <TABLE>

The fair value of each option  grant is estimated on the date of grant using the
Black-Scholes   option  pricing  model  with  the  following   weighted  average
assumptions used for grants in 1998, 1997 and 1996, respectively: dividend yield
of 0% for all years; expected volatility of 37%, 35% and 29%; risk-free interest
rates of 4.46%, 5.89% and 5.92%; and expected lives of five years for all years.
The  weighted  fair value of options  granted in 1998,  1997 and 1996 was $9.92,
$8.27 and $5.65, respectively.

The fair value of the look-back option implicit in each offering of the Purchase
Plan is estimated on the date of grant using the  Black-Scholes  option  pricing

14.        INTEGRATION, SETTLEMENT AND OTHER COSTS

1998

During the fourth  quarter of 1998,  the Company  incurred  settlement  expenses
totaling $8 million,  $5.9 million  after tax,  related to the  settlement  of a
competitor's protest for the Region 1 TRICARE contract. All this amount was paid
during fiscal year 1998.  On September  30, 1997,  SMHS was awarded a five-year,
$1.2 billion  contract to  administer  managed  health care services to military
families and retirees in 13 northeastern states and Washington, D.C. A competing
bidder  protested the contract award and claimed,  among other issues,  that the
United States Department of Defense failed to adequately disclose the weights of
the  significant  factors used to evaluate  proposals.  In December  1998,  SMHS
reached an  agreement  to settle the  protest.  As part of the  settlement,  the
competitor has foregone any and all rights it may have to challenge the contract
award and seek re-bid.

During the fourth quarter of 1998, the Company incurred integration,  transition
and other  charges  totaling  $3.1  million,  $2.3  million  after tax,  related
primarily to its acquisition of the Texas operations of Kaiser Foundation Health
Plan. In addition,  the Company  incurred  certain legal expenses  totaling $2.7
million, $2.0 million after tax, resulting primarily from the TRICARE settlement
and acquisition and integration  activity. As of December 31, 1998, $2.8 million
was included in accrued  expenses for these  integration,  transition  and legal
costs incurred through December 31, 1998.

1997

During 1997,  the Company  recorded  and paid  expenses of  approximately  $11.0
million,  $8.4 million after tax, for  merger-related  costs. On March 18, 1997,
the Company  announced it had  terminated  its merger  agreement  with Physician
Corporation of America. The original agreement had been entered into in November
1996.

              For the Years Ended December 31, 1998, 1997 and 1996


During  the third  quarter  of 1997,  SMHS was  notified  it had been  awarded a
TRICARE  managed care contract by the  Department  of Defense to serve  eligible
beneficiaries in Region 1. This region includes more than 600,000  beneficiaries
in 13 northeastern states and the District of Columbia.  Development expenses of
$18.4 million $10.6  million net of taxes,  were recorded in the third  quarter,
primarily for expenses  associated with the Company's  proposal to serve TRICARE
beneficiaries  in  Region  1.  Such  expenses  had  been  deferred  until  award
notification. SMHS began health care delivery on June 1, 1998. SMHS subcontracts
for health care  delivery,  including some of the risk, for parts of the TRICARE
contract.

1996

During 1995, as part of the Company's clinical expansion and growth efforts, the
Company acquired a medical facility in Mohave County, Arizona, across the border
from Laughlin,  Nevada. This medical facility included a 12-bed hospital. During
1996 the  Company  implemented  a plan to exit  the  hospital  business  and has
actively pursued buyers for this business. As a result of this plan, the Company
recorded a charge of $3.8 million, $2.9 million after tax, in the fourth quarter
of 1996,  primarily to recognize the estimated costs to dispose of the hospital.
As of December  31,  1998,  the Company has been unable to reach an agreement to
sell the hospital.

As a result of higher than expected claim and  administrative  costs relative to
premium rates that can be obtained in certain regional insurance  operations and
the  Company's  inability to negotiate  adequate  provider  contracts due to its
limited  presence  in some of  these  markets,  the  Company  adopted  a plan to
restructure  certain  insurance  operations during the third quarter of 1996 and
recorded a charge of $8.3 million,  $6.2 million after tax. These  restructuring
costs included cancellation of certain contractual  obligations of $6.0 million,
lease  termination  costs of $1.5  million and  approximately  $750,000 of other
costs.

The Company has three  reportable  segments  based on the  products and services
offered: managed care and corporate operations, workers' compensation operations
and military  health  services  operations.  The managed  care segment  includes
managed health care services  provided  through HMOs,  managed  indemnity plans,
third-party  administrative services programs for employer-funded health benefit
plans,  multi-specialty  medical groups,  other ancillary services and corporate
operations.  The workers'  compensation  segment assumes  workers'  compensation
claims risk in return for premium revenues. The military health services segment
administers  a five-year,  managed care federal  contract for the  Department of
Defense's TRICARE program in Region 1.

Sierra evaluates each segment's  performance  based on segment operating profit.
The  accounting  policies  of the  operating  segments  are the  same  as  those

                                                   ARTICLE II
                                                    THE CREDITS

         2.01  Amounts and Terms of Commitments.  Each Bank severally
agrees, on the terms and conditions set forth herein, to make
loans to the Company (each such loan, a "Revolving Loan") from
time to time on any Business Day during the period from the
Closing Date to the Revolving Termination Date, in an aggregate
amount not to exceed at any time outstanding the amount set forth
on Schedule 2.01 (such amount as the same may be reduced under
Section 2.05 or increased under Section 2.08 or as a result of
one or more assignments under Section 10.08, the Bank's
"Commitment"); provided, however, that, after giving effect to
any Borrowing of Revolving Loans, the Effective Amount of all
outstanding Revolving Loans and the Effective Amount of all L/C
Obligations, shall not at any time exceed the combined
Commitments; and provided further, that the Effective Amount of
the Revolving Loans of any Bank plus the participation of such
Bank in the Effective Amount of all L/C Obligations shall not at
any time exceed such Bank's Commitment.  Within the limits of
each Bank's Commitment, and subject to the other terms and
conditions hereof, the Company may borrow under this section
2.01, prepay under Section 2.06 and reborrow under this section
2.01.

         2.02  Loan Accounts.

                  (a)      The Loans made by each Bank and the Letters of
Credit Issued by the Issuing Bank shall be evidenced by one or
more accounts or records maintained by such Bank or Issuing Bank,
as the case may be, in the ordinary course of business.  The
accounts or records maintained by the Agent, the Issuing Bank and
each Bank shall be presumptive evidence of the amount of the
Loans made by the Banks to the Company and the Letters of Credit
Issued for the account of the Company, and the interest and
payments thereon.  Any failure to so maintain such accounts or
records, or any error in doing so, shall not, however, limit or
otherwise affect the obligation of the Company hereunder to pay
any amount owing with respect to the Loans or any Letter of
Credit.

                  (b)      Upon the request of any Bank made through the
Agent, the Loans made by such Bank may be evidenced by one or
more Notes, instead of or in addition to loan accounts.  Each
such Bank shall endorse on the schedules annexed to its Note(s)
the date, amount and maturity of each Loan made by it and the
amount of each payment of principal made by the Company with

 
                                                        28


respect thereto.  Each such Bank is irrevocably authorized by the
Company to endorse its Note(s) and each Bank's record shall be
conclusive absent manifest error; provided, however, that the
failure of a Bank to make, or an error in making, a notation
thereon with respect to any Loan shall not limit or otherwise
affect the obligations of the Company hereunder or under any such
Note to such Bank.

         2.03  Procedure for Borrowing.

                  (a)      Each Borrowing of Revolving Loans shall be made
upon the Company's irrevocable written notice delivered to the
Agent in the form of a Notice of Borrowing (which notice must be
received by the Agent prior to 10:00 a.m. (San Francisco time)
(i) three Business Days prior to the requested Borrowing Date, in
the case of LIBOR Rate Loans, and (ii) one Business Day prior to
the requested Borrowing Date, in the case of Base Rate Loans,
specifying:

                                    (A)     the amount of the Borrowing, which
         shall be, in the case of LIBOR Rate Loans, in an
         aggregate minimum amount of $5,000,000 or any multiple
         of $1,000,000 in excess thereof and, in the case of
         Base Rate Loans, in an aggregate minimum amount of
         $1,000,000 or any multiple of $100,000 in excess
         thereof;

                                    (B)     the requested Borrowing Date, which
         shall be a Business Day;

                                    (C)     the Type of Loans comprising the
         Borrowing; and

                                    (D)     if such Borrowing is comprised of
         LIBOR Rate Loans, the duration of the Interest Period
         applicable to such Loans included in such notice.  If
         the Notice of Borrowing fails to specify the duration
         of the Interest Period for any Borrowing comprised of
         LIBOR Rate Loans, such Interest Period shall be one
         month.

                  (b)      The Agent will promptly notify each Bank of its
receipt of any Notice of Borrowing and of the amount of such
Bank's Pro Rata Share of that Borrowing.

                  (c)      Each Bank will make the amount of its Pro Rata
Share of each Borrowing available to the Agent for the account of
the Company at the Agent's Payment Office by 11:00 a.m. (San

 
                                                        29


Francisco time) on the Borrowing Date requested by the Company in
funds immediately available to the Agent.  The proceeds of all
such Loans will then be made available to the Company by the
Agent by wire transfer in accordance with written instructions
provided to the Agent by the Company of like funds as received by
the Agent.

                  (d)      After giving effect to any Borrowing, unless the
Agent shall otherwise consent, there may not be more than ten
(10) different Interest Periods in effect.

         2.04  Conversion and Continuation Elections.

                  (a)      The Company may, upon irrevocable written notice
to the Agent in accordance with subsection 2.04(b):

                           (i) elect, as of any Business Day, in the case of
         Base Rate Loans, to convert any such Loans (or any part
         thereof in an amount not less than $5,000,000, or that is in
         an integral multiple of $1,000,000 in excess thereof) into
         LIBOR Rate Loans;

                           (ii) elect, as of the last day of the
         applicable Interest Period, in the case of LIBOR Rate
         Loans, to convert any such Loans (or any part thereof
         in an amount not less than $1,000,000, or that is in an
         integral multiple of $100,000 in excess thereof) into
         Base Rate Loans; or

                           (iii) elect as of the last day of the applicable
         Interest Period, in the case of LIBOR Rate Loans, to
         continue any such Loans having Interest Periods expiring on
         such day (or any part thereof in an amount not less than
         $5,000,000, or that is in an integral multiple of $1,000,000
         in excess thereof);

provided, that if at any time the aggregate amount of LIBOR Rate
Loans in respect of any Borrowing is reduced, by payment,
prepayment, or conversion of part thereof to be less than
$5,000,000, such LIBOR Rate Loans shall automatically convert
into Base Rate Loans, and on and after such date the right of the
Company to continue such Loans as, and convert such Loans into,
LIBOR Rate Loans, shall terminate.

                  (b)      The Company shall deliver a Notice of
Conversion/Continuation to be received by the Agent not later
than 9:00 a.m. (San Francisco time) at least (i) three Business
Days in advance of the Conversion/ Continuation Date, if the

 
                                                        30

Loans are to be converted into or continued as LIBOR Rate Loans,
and (ii) one Business Day in advance of the Conversion/
Continuation Date, if the Loans are to be converted into Base
Rate Loans, specifying:

                               (A)     the proposed Conversion/Continuation
         Date;

                               (B)     the aggregate amount of Loans to be
         converted or continued;

                               (C)     the Type of Loans resulting from the
         proposed conversion or continuation; and

                               (D)     other than in the case of conversions
         into Base Rate Loans, the duration of the requested Interest
         Period.

                  (c)      If upon the expiration of any Interest Period
applicable to LIBOR Rate Loans, the Company has failed to select
timely a new Interest Period to be applicable to such LIBOR Rate
Loans, the Company shall be deemed to have elected to convert
such LIBOR Rate Loans into Base Rate Loans effective as of the
expiration date of such Interest Period.

                  (d)      The Agent will promptly notify each Bank of its
receipt of a Notice of Conversion/ Continuation, or, if no timely
notice is provided by the Company, the Agent will promptly notify
each Bank of the details of any automatic conversion. All
conversions and continuations shall be made ratably according to
the respective outstanding principal amounts of the Loans with
respect to which the notice was given held by each Bank.

                  (e)      Unless the Majority Banks otherwise consent,
during the existence of a Default or Event of Default, the
Company may not elect to have a Loan converted into or continued
as a LIBOR Rate Loan.

                  (f)      After giving effect to any conversion or
continuation of Loans, unless the Agent shall otherwise consent,
there may not be more than ten (10) different Interest Periods in
effect.

         2.05  Voluntary Termination or Reduction of Commitments. The
Company may, upon not less than three Business Days' prior notice
to the Agent, terminate the Commitments, or permanently reduce
the Commitments by an aggregate minimum amount of $5,000,000 or
any multiple of $1,000,000 in excess thereof; unless, after

 
                                                        31


giving effect thereto and to any prepayments of Loans made on the
effective date thereof, (i) the Effective Amount of all Revolving
Loans and L/C Obligations together would exceed the amount of the
combined Commitments then in effect, or (ii) the Effective Amount
of all L/C Obligations then outstanding would exceed the L/C
Commitment.  Once reduced in accordance with this Section, the
Commitments may not be increased.  Any reduction of the
Commitments shall be applied to each Bank according to its Pro
Rata Share.  If and to the extent specified by the Company in the
notice to the Agent, some or all of the reduction in the combined
Commitments shall be applied to reduce the L/C Commitment.  All
accrued commitment and letter of credit fees to, but not
including, the effective date of any reduction or termination of
Commitments, shall be paid on the effective date of such
reduction or termination.

         2.06  Optional Prepayments. Subject to Section 4.04, the
Company may, at any time or from time to time, upon not less than
(i) three Business Days' irrevocable notice to the Agent, ratably
prepay LIBOR Rate Loans in whole or in part, in minimum amounts
of $5,000,000 or any multiple of $1,000,000 in excess thereof,
and (ii) one Business Day's irrevocable notice to the Agent,
ratably prepay Base Rate Loans in whole or in part, in minimum
amounts of $1,000,000 or any multiple of $100,000 in excess
thereof.  Such notice of prepayment shall specify the date and
amount of such prepayment and the Type(s) of Loans to be prepaid.
The Agent will promptly notify each Bank of its receipt of any
such notice, and of such Bank's Pro Rata Share of such
prepayment.  If such notice is given by the Company, the Company
shall make such prepayment and the payment amount specified in
such notice shall be due and payable on the date specified
therein, together with accrued interest to each such date on the
amount prepaid and any amounts required pursuant to Section 4.04.
Amounts so prepaid may be reborrowed subject to the applicable
provisions of this Agreement.

         2.07  Mandatory Prepayments of Loans; Mandatory Commitment
Reductions and Repayments.

                  (a)      If on any date the Effective Amount of L/C
Obligations exceeds the L/C Commitment, the Company shall Cash
Collateralize on such date the outstanding Letters of Credit in
an amount equal to the excess of the maximum amount then
available to be drawn under the Letters of Credit over the
Aggregate L/C Commitment.  Subject to Section 4.04, if on any
date after giving effect to any Cash Collateralization made on
such date pursuant to the preceding sentence, the Effective
Amount of all Revolving Loans then outstanding plus the Effective

 
                                                        32

Amount of all L/C Obligations exceeds the combined Commitments,
the Company shall immediately, and without notice or demand,
prepay the outstanding principal amount of the Revolving Loans
and L/C Advances by an amount equal to the applicable excess.

                  (b)      On each date set forth below, the aggregate
Commitments shall, without any further action, automatically and
permanently be reduced to the amount set forth opposite such
date:

                           Date                                  Amount

                  June 30, 2001                               $205,000,000*/
                  December 31, 2001                           $185,000,000
                  June 30, 2002                               $165,000,000
                  December 31, 2002                           $145,000,000
                  June 30, 2003                               $125,000,000

provided, however, that on the Revolving Termination Date, the
aggregate Commitments shall be zero and on such date the Company
shall repay to the Banks the aggregate principal amount of Loans
outstanding on such date.

                  (c)      If the aggregate Commitments equal or exceed
$100,000,000, the aggregate Commitments shall be automatically
and permanently reduced (but not to an amount below $100,000,000)
by an amount equal to seventy-five percent (75%) of the first
$25,000,000 of Net Cash Proceeds and one hundred percent (100%)
of all Net Cash Proceeds in excess thereof received by the
Company or its Subsidiary from a sale or disposition of any asset
(including, without limitation, any sale or disposition by the
Company of any capital stock of any of its Subsidiaries) other
than up to $10,000,000 in any fiscal year of Net Cash Proceeds
from asset sales in the ordinary course of business; provided,
however, that so long as no Default or Event of Default shall
have occurred and then be continuing, the aggregate Commitments
shall not be required to be reduced under this Section 2.07(c) if
and to the extent the Company or one of its Subsidiaries has used
such Net Cash Proceeds within 180 days of the receipt thereof for
Capital Expenditures or Acquisitions (in accordance with the
provisions of Article VI hereof) in the existing lines of
business of the Company; provided, further, that in no event
shall the Net Cash Proceeds used by the Company or its
Subsidiaries in accordance with the previous proviso exceed
$10,000,000 in any fiscal year or $25,000,000 during the term of
this Agreement.  The reduction in the aggregate Commitments
- --------
*/Applicable only if the commitments have been increased pursuant
to
 Section 2.08.

 
                                                        33


contemplated by this Section 2.07(c) shall occur no later than
the earlier of (i) the tenth day after receipt by the Company or
its Subsidiary of Net Cash Proceeds, unless prior to such date
the Company shall have provided the Agent with written notice of
its intention to reinvest such proceeds in accordance with the
terms of the preceding sentence, or (ii) the date which is 180
days from the date of receipt by the Company or its Subsidiary of
such Net Cash Proceeds subject, in the case of asset sales by
regulated Subsidiaries of the Company, to the compliance by such
Subsidiaries with any applicable Requirements of Law.  Any
reduction in the aggregate Commitment pursuant to this Section
2.07(c) shall be applied to reduce any remaining scheduled
installments in inverse order of maturity.

         2.08  Increase to the Commitment.

                  (a) On or before April 30, 1999, the Company may by
written notice to the Agent, request proposed increases to the
amount of the Commitments to be effective on a date to be
specified by the Company (the "Commitment Increase Date"),
provided that (i) as of the Commitment Increase Date, no Default
or Event of Default shall have occurred, (ii) each such request
shall be for an increase in the Commitments which is in an
integral multiple of $5,000,000 and (iii) without the prior
written consent of all of the Banks, no such increase shall
result in the aggregate principal amount of the Commitments being
in excess of $225,000,000.  Nothing contained in this Section
2.08 shall be construed as a commitment on behalf of the Agent or
any Bank to assume any increase in the Commitments.

                  (b)      Each Person which assumes any portion of an
increase to the Commitments shall be a Bank or a willing
financial institution which qualifies as an Eligible Assignee and
which is designated by the Agent or the Syndication Agent.

                  (c)      The Borrower, each such Eligible Assignee or Bank
and the Agent shall execute and deliver a Joinder Agreement, and
Company shall deliver a Note to each such Eligible Assignee in
the amount of its Commitment.  Upon the Commitment Increase Date,
the Eligible Assignee or Bank named therein shall become a Bank
for all purposes of the Loan Documents, with the Commitment
therein set forth.

                  (d)      By executing and delivering a Joinder Agreement,
the Eligible Assignee or Bank named therein acknowledges and
agrees as of the Commitment Increase Date that (i) it has
received a copy of this Agreement, together with copies of the
most recent financial statements delivered pursuant to Section
7.01 and such other documents and information as it has deemed

 
                                                        34

appropriate to make its own credit analysis and decision to enter
into such Joinder Agreement; (ii) it will, independently and
without reliance upon the Agent, the Syndication Agent or any
Bank and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit
decisions in taking or not taking action under this Agreement;
(iii) it appoints and authorizes the Agent to take such action
and to exercise such powers under this Agreement as are delegated
to the Agent by this Agreement; and (iv) it will perform in
accordance with their terms all of the obligations which by the
terms of this Agreement are required to be performed by it as a
Bank.

                  (e)      The Agent shall maintain a copy of each Joinder
Agreement, shall promptly inform the Banks of the identity of
each Bank which executes a Joinder Agreement and provide each
Bank and the Company with a revised Schedule 2.01 to this
Agreement.

         2.09  Interest.

                  (a)      Each Revolving Loan shall bear interest on the
outstanding principal amount thereof from the applicable
Borrowing Date at a rate per annum equal to the LIBOR Rate or the
Base Rate, as the case may be (and subject to the Company's right
to convert to other Types of Loans under Section 2.04), plus the
Applicable Margin.

                  (b)      Interest on each Revolving Loan shall be paid in
arrears on each Interest Payment Date. Interest shall also be
paid on the date of any prepayment of LIBOR Rate Loans under
Section 2.06 or 2.07 for the portion of the Loans so prepaid and
upon payment (including prepayment) in full thereof and, during
the existence of any Event of Default, interest on all Loans
shall be paid on demand of the Agent at the request or with the
consent of the Majority Banks.

                  (c)      Notwithstanding subsection (a) of this Section,
while any Event of Default exists or after acceleration, the
Company shall pay interest (after as well as before entry of
judgment thereon to the extent permitted by law) on the principal
amount of all outstanding Obligations, at a rate per annum which
is determined by adding 2% per annum to the Applicable Margin
then in effect for such Loans and, in the case of Obligations not
subject to an Applicable Margin, at a rate per annum equal to the
Base Rate plus 2%; provided, however, that, on and after the
expiration of any Interest Period applicable to any LIBOR Rate
Loan outstanding on the date of occurrence of such Event of

 
                                                        35


Default or acceleration, the principal amount of such Loan shall,
during the continuation of such Event of Default or after
acceleration, bear interest at a rate per annum equal to the Base
Rate plus the Applicable Margin for Base Rate Loans plus 2%.

                  (d)      Anything herein to the contrary notwithstanding,
the obligations of the Company to any Bank hereunder shall be
subject to the limitation that payments of interest shall not be
required for any period for which interest is computed hereunder,
to the extent (but only to the extent) that contracting for or
receiving such payment by such Bank would be contrary to the
provisions of any law applicable to such Bank limiting the
highest rate of interest that may be lawfully contracted for,
charged or received by such Bank, and in such event the Company
shall pay such Bank interest at the highest rate permitted by
applicable law.

         2.10  Fees.  In addition to certain fees described in
Section 3.08:

                  (a)      Agents' Fees.  The Company shall pay fees to the
Agent and the Syndication Agent for their own account, as
required by the letter agreement ("Fee Letter") between the
Company, the Agent and the Syndication Agent dated October 1,
1998.

                  (b)      Commitment Fees.  The Company shall pay to the
Agent for the account of each Bank a commitment fee on the
average daily unused portion of such Bank's Commitment, computed
on a quarterly basis in arrears on the last Business Day of each
fiscal quarter, equal to the product of (i) the Applicable
Commitment Fee Rate and (ii) the average daily unused portion of
such Bank's Commitment during such fiscal quarter.  For purposes
of calculating utilization under this subsection, the Commitments
shall be deemed used to the extent of the Effective Amount of
Revolving Loans then outstanding, plus the Effective Amount of
L/C Obligations then outstanding.  Such commitment fee shall
accrue from the Closing Date to the Revolving Termination Date
and shall be due and payable quarterly in arrears on the last day
of each March, June, September and December, commencing
December 31, 1998 through the Revolving Termination Date, with
the final payment to be made on the Revolving Termination Date;
provided that, in connection with any reduction or termination of
Commitments under Section 2.05 or Section 2.07, the accrued
commitment fee calculated for the period ending on such date
shall also be paid on the date of such reduction or termination,
with the following quarterly payment being calculated on the
basis of the period from such reduction or termination date to

 
                                                        36

such quarterly payment date.  The commitment fees provided in
this subsection shall accrue at all times after the above-
mentioned commencement date, including at any time during which
one or more conditions in Article V are not met.

         2.11  Computation of Fees and Interest.

                  (a)      All computations of interest for Base Rate Loans
when the Base Rate is determined by BofA's "reference rate" shall
be made on the basis of a year of 365 or 366 days, as the case
may be, and actual days elapsed.  All other computations of fees
and interest shall be made on the basis of a 360-day year and
actual days elapsed (which results in more interest being paid
than if computed on the basis of a 365-day year).  Interest and
fees shall accrue during each period during which interest or
such fees are computed from the first day thereof to the last day
thereof.

                  (b)      Each determination of an interest rate by the
Agent shall be conclusive and binding on the Company and the
Banks in the absence of manifest error.  The Agent will, at the
request of the Company or any Bank, deliver to the Company or the
Bank, as the case may be, a statement showing the quotations used
by the Agent in determining any interest rate and the resulting
interest rate.

         2.12  Payments by the Company.

                  (a)      All payments to be made by the Company shall be
made without set-off, recoupment or counterclaim.  Except as
otherwise expressly provided herein, all payments by the Company
shall be made to the Agent for the account of the Banks at the
Agent's Payment Office, and shall be made in dollars and in
immediately available funds, no later than 11:00 a.m. (San
Francisco time) on the date specified herein.  The Agent will
promptly distribute to each Bank its Pro Rata Share (or other
applicable share as expressly provided herein) of such payment in
like funds as received.  Any payment received by the Agent later
than 11:00 a.m. (San Francisco time) shall be deemed to have been
received on the following Business Day and any applicable
interest or fee shall continue to accrue.

                  (b)      Subject to the provisions set forth in the
definition of "Interest Period" herein, whenever any payment is
due on a day other than a Business Day, such payment shall be
made on the following Business Day, and such extension of time
shall in such case be included in the computation of interest or
fees, as the case may be.

 
                                                        37


                  (c)      Unless the Agent receives notice from the Company
prior to the date on which any payment is due to the Banks that
the Company will not make such payment in full as and when
required, the Agent may assume that the Company has made such
payment in full to the Agent on such date in immediately
available funds and the Agent may (but shall not be so required),
in reliance upon such assumption, distribute to each Bank on such
due date an amount equal to the amount then due such Bank.  If
and to the extent the Company has not made such payment in full
to the Agent, each Bank shall repay to the Agent on demand such
amount distributed to such Bank, together with interest thereon
at the Federal Funds Rate for each day from the date such amount
is distributed to such Bank until the date repaid.

         2.13  Payments by the Banks to the Agent.

                  (a)      Unless the Agent receives notice from a Bank on or
prior to the Closing Date or, with respect to any Borrowing after
the Closing Date, at least one Business Day prior to the date of
such Borrowing, that such Bank will not make available as and
when required hereunder to the Agent for the account of the
Company the amount of that Bank's Pro Rata Share of the
Borrowing, the Agent may assume that each Bank has made such
amount available to the Agent in immediately available funds on
the Borrowing Date and the Agent may (but shall not be so
required), in reliance upon such assumption, make available to
the Company on such date a corresponding amount.  If and to the
extent any Bank shall not have made its full amount available to
the Agent in immediately available funds and the Agent in such
circumstances has made available to the Company such amount, that
Bank shall on the Business Day following such Borrowing Date make
such amount available to the Agent, together with interest at the
Federal Funds Rate for each day during such period.  A notice of
the Agent submitted to any Bank with respect to amounts owing
under this subsection (a) shall be conclusive, absent manifest
error. If such amount is so made available, such payment to the
Agent shall constitute such Bank's Loan on the date of Borrowing
for all purposes of this Agreement.  If such amount is not made
available to the Agent on the Business Day following the
Borrowing Date, the Agent will notify the Company of such failure
to fund and, upon demand by the Agent, the Company shall pay such
amount to the Agent for the Agent's account, together with
interest thereon for each day elapsed since the date of such
Borrowing, at a rate per annum equal to the interest rate
applicable at the time to the Loans comprising such Borrowing.

                  (b)      The failure of any Bank to make any Loan on any
Borrowing Date shall not relieve any other Bank of any obligation

 
                                                        38

hereunder to make a Loan on such Borrowing Date, but no Bank
shall be responsible for the failure of any other Bank to make
the Loan to be made by such other Bank on any Borrowing Date.

         2.14  Sharing of Payments, Etc.  If, other than as expressly
provided elsewhere herein, any Bank shall obtain on account of
the Loans made by it any payment (whether voluntary, involuntary,
through the exercise of any right of set-off, or otherwise) in
excess of its ratable share (or other share contemplated
hereunder), such Bank shall immediately (a) notify the Agent of
such fact, and (b) purchase from the other Banks such
participations in the Loans made by them as shall be necessary to
cause such purchasing Bank to share the excess payment pro rata
with each of them; provided, however, that if all or any portion
of such excess payment is thereafter recovered from the
purchasing Bank, such purchase shall to that extent be rescinded
and each other Bank shall repay to the purchasing Bank the
purchase price paid therefor, together with an amount equal to
such paying Bank's ratable share (according to the proportion of
(i) the amount of such paying Bank's required repayment to
(ii) the total amount so recovered from the purchasing Bank) of
any interest or other amount paid or payable by the purchasing
Bank in respect of the total amount so recovered.  The Company
agrees that any Bank so purchasing a participation from another
Bank may, to the fullest extent permitted by law, exercise all
its rights of payment (including the right of set-off, but
subject to Section 11.10) with respect to such participation as
fully as if such Bank were the direct creditor of the Company in
the amount of such participation. The Agent will keep records
(which shall be conclusive and binding in the absence of manifest
error) of participations purchased under this Section and will in
each case notify the Banks following any such purchases or
repayments.

         2.15  Security.  All obligations of the Company under this
Agreement, the Notes all other Loan Documents and any Swap
Contract entered into with a Bank and permitted under this
Agreement shall be secured in accordance with the Collateral
Documents.


                                                    ARTICLE III
                                               THE LETTERS OF CREDIT

         3.01  The Letter of Credit Subfacility.

                  (a)      On the terms and conditions set forth herein (i)
the Issuing Bank agrees, (A) from time to time on any Business

 
                                                        39


Day during the period from the Closing Date to the Revolving
Termination Date to issue Letters of Credit for the account of
the Company, and to amend or renew Letters of Credit previously
issued by it, in accordance with subsections 3.02(c) and 3.02(d),
and (B) to honor drafts under the Letters of Credit; and (ii) the
Banks severally agree to participate in Letters of Credit Issued
for the account of the Company; provided, that the Issuing Bank
shall not be obligated to Issue, and no Bank shall be obligated
to participate in, any Letter of Credit if as of the date of
Issuance of such Letter of Credit (the "Issuance Date") (1) the
Effective Amount of all L/C Obligations plus the Effective Amount
of all Revolving Loans exceeds the combined Commitments, (2) the
participation of any Bank in the Effective Amount of all L/C
Obligations plus the Effective Amount of the Revolving Loans of
such Bank exceeds such Bank's Commitment, or (3) the Effective
Amount of L/C Obligations exceeds the L/C Commitment.  Within the
foregoing limits, and subject to the other terms and conditions
hereof, the Company's ability to obtain Letters of Credit shall
be fully revolving, and, accordingly, the Company may, during the
foregoing period, obtain Letters of Credit to replace Letters of
Credit which have expired or which have been drawn upon and
reimbursed.

                  (b)      The Issuing Bank is under no obligation to Issue
any Letter of Credit if:

                           (i) any order, judgment or decree of any
         Governmental Authority or arbitrator shall by its terms
         purport to enjoin or restrain the Issuing Bank from Issuing
         such Letter of Credit, or any Requirement of Law applicable
         to the Issuing Bank or any request or directive (whether or
         not having the force of law) from any Governmental Authority
         with jurisdiction over the Issuing Bank shall prohibit, or
         request that the Issuing Bank refrain from, the Issuance of
         letters of credit generally or such Letter of Credit in
         particular or shall impose upon the Issuing Bank with
         respect to such Letter of Credit any restriction, reserve or
         capital requirement (for which the Issuing Bank is not
         otherwise compensated hereunder) not in effect on the
         Closing Date, or shall impose upon the Issuing Bank any
         unreimbursed loss, cost or expense which was not applicable
         on the Closing Date and which the Issuing Bank in good faith
         deems material to it;

                           (ii) the Issuing Bank has received written notice
         from any Bank, the Agent or the Company, on or prior to the
         Business Day prior to the requested date of Issuance of such

 
                                                        40

        Letter of Credit, that one or more of the applicable
         conditions contained in Article V is not then satisfied;

                           (iii) the expiry date of any requested Letter of
         Credit is (A) more than 364 days after the date of Issuance,
         unless the Majority Banks have approved such expiry date in
         writing, or (B) later than thirty days prior to the
         Revolving Termination Date;

                           (iv) any requested Letter of Credit does not
         provide for drafts, or is not otherwise in form and
         substance acceptable to the Issuing Bank, or the Issuance of
         a Letter of Credit shall violate any applicable policies of
         the Issuing Bank;

                           (v) any requested Letter of Credit is for the
         purpose of supporting the issuance of any letter of credit
         by any other Person; or

                           (vi) such Letter of Credit is in a face amount
         less than $500,000 or to be denominated in a currency other
         than Dollars.

         3.02  Issuance, Amendment and Renewal of Letters of Credit.

                  (a)      Each Letter of Credit shall be issued upon the
irrevocable written request of the Company received by the
Issuing Bank (with a copy sent by the Company to the Agent) at
least four days (or such shorter time as the Issuing Bank may
agree in a particular instance in its sole discretion) prior to
the proposed date of issuance.  Each such request for issuance of
a Letter of Credit shall be by facsimile, confirmed immediately
in an original writing, in the form of an L/C Application, and
shall specify in form and detail satisfactory to the Issuing
Bank:

                           (i) the proposed date of issuance of the
         Letter of Credit (which shall be a Business Day);

                           (ii) the face amount of the Letter of Credit;

                           (iii) the expiry date of the Letter of
         Credit;

                           (iv) the name and address of the beneficiary
         thereof;


 
                                                        41


                           (v) the documents to be presented by the
         beneficiary of the Letter of Credit in case of any
         drawing thereunder;

                           (vi) the full text of any certificate to be
         presented by the beneficiary in case of any drawing
         thereunder; and

                           (vii) such other matters as the Issuing Bank
         may require.

                  (b)      At least two Business Days prior to the Issuance
of any Letter of Credit, the Issuing Bank will confirm with the
Agent (by telephone or in writing) that the Agent has received a
copy of the L/C Application or L/C Amendment Application from the
Company and, if not, the Issuing Bank will provide the Agent with
a copy thereof.  Unless the Issuing Bank has received notice on
or before the Business Day immediately preceding the date the
Issuing Bank is to issue a requested Letter of Credit from the
Agent (A) directing the Issuing Bank not to issue such Letter of
Credit because such issuance is not then permitted under
subsection 3.01(a) as a result of the limitations set forth in
clauses (1) through (3) thereof or subsection 3.01(b)(ii); or
(B) that one or more conditions specified in Article V are not
then satisfied; then, subject to the terms and conditions hereof,
the Issuing Bank shall, on the requested date, issue a Letter of
Credit for the account of the Company in accordance with the
Issuing Bank's usual and customary business practices.

                  (c)      From time to time while a Letter of Credit is
outstanding and prior to the Revolving Termination Date, the
Issuing Bank will, upon the written request of the Company
received by the Issuing Bank (with a copy sent by the Company to
the Agent) at least four days (or such shorter time as the
Issuing Bank may agree in a particular instance in its sole
discretion) prior to the proposed date of amendment, amend any
Letter of Credit issued by it. Each such request for amendment of
a Letter of Credit shall be made by facsimile, confirmed
immediately in an original writing, made in the form of an L/C
Amendment Application and shall specify in form and detail
satisfactory to the Issuing Bank: (i) the Letter of Credit to be
amended; (ii) the proposed date of amendment of the Letter of
Credit (which shall be a Business Day); (iii) the nature of the
proposed amendment; and (iv) such other matters as the Issuing
Bank may require.  The Issuing Bank shall be under no obligation
to amend any Letter of Credit if: (A) the Issuing Bank would have
no obligation at such time to issue such Letter of Credit in its
amended form under the terms of this Agreement; or (B) the

 
                                                        42

beneficiary of any such Letter of Credit does not accept the
proposed amendment to the Letter of Credit.  The Agent will
promptly notify the Banks of the receipt by it of any L/C
Application or L/C Amendment Application.

                  (d)      The Issuing Bank and the Banks agree that, while a
Letter of Credit is outstanding and prior to the Revolving
Termination Date, at the option of the Company and upon the
written request of the Company received by the Issuing Bank (with
a copy sent by the Company to the Agent) at least four days (or
such shorter time as the Issuing Bank may agree in a particular
instance in its sole discretion) prior to the proposed date of
notification of renewal, the Issuing Bank shall be entitled to
authorize the automatic renewal of any Letter of Credit issued by
it.  Each such request for renewal of a Letter of Credit shall be
made by facsimile, confirmed immediately in an original writing,
in the form of an L/C Amendment Application, and shall specify in
form and detail satisfactory to the Issuing Bank: (i) the Letter
of Credit to be renewed; (ii) the proposed date of notification
of renewal of the Letter of Credit (which shall be a Business
Day); (iii) the revised expiry date of the Letter of Credit; and
(iv) such other matters as the Issuing Bank may require.  The
Issuing Bank shall be under no obligation so to renew any Letter
of Credit if: (A) the Issuing Bank would have no obligation at
such time to issue or amend such Letter of Credit in its renewed
form under the terms of this Agreement; or (B) the beneficiary of
any such Letter of Credit does not accept the proposed renewal of
the Letter of Credit.  If any outstanding Letter of Credit shall
provide that it shall be automatically renewed unless the
beneficiary thereof receives notice from the Issuing Bank that
such Letter of Credit shall not be renewed, and if at the time of
renewal the Issuing Bank would be entitled to authorize the
automatic renewal of such Letter of Credit in accordance with
this subsection 3.02(e) upon the request of the Company but the
Issuing Bank shall not have received any L/C Amendment
Application from the Company with respect to such renewal or
other written direction by the Company with respect thereto, the
Issuing Bank shall nonetheless be permitted to allow such Letter
of Credit to renew, and the Company and the Banks hereby
authorize such renewal, and, accordingly, the Issuing Bank shall
be deemed to have received an L/C Amendment Application from the
Company requesting such renewal.

                  (e)      The Issuing Bank may, at its election (or as
required by the Agent at the direction of the Majority Banks),
deliver any notices of termination or other communications to any
Letter of Credit beneficiary or transferee, and take any other
action as necessary or appropriate, at any time and from time to

 
                                                        43


time, in order to cause the expiry date of such Letter of Credit
to be a date not later than the Revolving Termination Date.

                  (f)      This Agreement shall control in the event of any
conflict with any L/C-Related Document (other than any Letter of
Credit).

                  (g)      The Issuing Bank will also deliver to the Agent,
concurrently or promptly following its delivery of a Letter of
Credit, or amendment to or renewal of a Letter of Credit, to an
advising bank or a beneficiary, a true and complete copy of each
such Letter of Credit or amendment to or renewal of a Letter of
Credit.

         3.03  Existing BofA Letters of Credit; Risk Participations,
Drawings and Reimbursements.

                  (a)      On and after the Closing Date, the Existing BofA
Letters of Credit shall be deemed for all purposes, including for
purposes of the fees to be collected pursuant to subsections
3.08(a) and 3.08(b), and reimbursement of costs and expenses to
the extent provided herein, Letters of Credit outstanding under
this Agreement and entitled to the benefits of this Agreement and
the other Loan Documents, and shall be governed by the
applications and agreements pertaining thereto and by this
Agreement.  Each Bank shall be deemed to, and hereby irrevocably
and unconditionally agrees to, purchase from the Issuing Bank on
the Closing Date or on the Commitment Increase Date a
participation in each such Letter of Credit and each drawing
thereunder in an amount equal to the product of  such Bank's Pro
Rata Share times  the maximum amount available to be drawn under
such Letter of Credit and the amount of such drawing,
respectively.  For purposes of subsection 2.01(b) and subsection
2.10(b), the Existing BofA Letters of Credit shall be deemed to
utilize pro rata the Commitment of each Bank.

                  (b)      Immediately upon the Issuance of each Letter of
Credit in addition to those described in subsection 3.3(a), each
Bank shall be deemed to, and hereby irrevocably and
unconditionally agrees to, purchase from the Issuing Bank a
participation in such Letter of Credit and each drawing
thereunder in an amount equal to the product of (i) the Pro Rata
Share of such Bank, times (ii) the maximum amount available to be
drawn under such Letter of Credit and the amount of such drawing,
respectively.  For purposes of subsection 2.01(b), each Issuance
of a Letter of Credit shall be deemed to utilize the Commitment
of each Bank by an amount equal to the amount of such
participation.


 
                                                        44

                 (c)      In the event of any request for a drawing under a
Letter of Credit by the beneficiary or transferee thereof, the
Issuing Bank will promptly notify the Company.  The Company shall
reimburse the Issuing Bank prior to 10:00 a.m. (San Francisco
time), on each date that any amount is paid by the Issuing Bank
under any Letter of Credit (each such date, an "Honor Date"), in
an amount equal to the amount so paid by the Issuing Bank.  In
the event the Company fails to reimburse the Issuing Bank for the
full amount of any drawing under any Letter of Credit by 10:00
a.m. (San Francisco time) on the Honor Date, the Issuing Bank
will promptly notify the Agent and the Agent will promptly notify
each Bank thereof, and the Company shall be deemed to have
requested that Base Rate Loans be made by the Banks to be
disbursed on the Honor Date under such Letter of Credit, subject
to the amount of the unutilized portion of the Revolving
Commitment and subject to the conditions set forth in Section
5.02.  Any notice given by the Issuing Bank or the Agent pursuant
to this subsection 3.03(c) may be oral if immediately confirmed
in writing (including by facsimile); provided that the lack of
such an immediate confirmation shall not affect the
conclusiveness or binding effect of such notice.

                  (d)      Each Bank shall upon any notice pursuant to
subsection 3.03(c) make available to the Agent for the account of
the relevant Issuing Bank an amount in Dollars and in immediately
available funds equal to its Pro Rata Share of the amount of the
drawing, whereupon the participating Banks shall (subject to
subsection 3.03(e)) each be deemed to have made a Loan consisting
of a Base Rate Loan to the Company in that amount.  If any Bank
so notified fails to make available to the Agent for the account
of the Issuing Bank the amount of such Bank's Pro Rata Share of
the amount of the drawing by no later than 12:00 noon (San
Francisco time) on the Honor Date, then interest shall accrue on
such Bank's obligation to make such payment, from the Honor Date
to the date such Bank makes such payment, at a rate per annum
equal to the Federal Funds Rate in effect from time to time
during such period.  The Agent will promptly give notice of the
occurrence of the Honor Date, but failure of the Agent to give
any such notice on the Honor Date or in sufficient time to enable
any Bank to effect such payment on such date shall not relieve
such Bank from its obligations under this Section 3.03.

                  (e)      With respect to any unreimbursed drawing that is
not converted into Loans consisting of Base Rate Loans to the
Company in whole or in part, because of the Company's failure to
satisfy the conditions set forth in Section 5.02 or for any other
reason, the Company shall be deemed to have incurred from the
Issuing Bank an L/C Borrowing in the amount of such drawing,

 
                                                        45


which L/C Borrowing shall be due and payable on demand (together
with interest) and shall bear interest at a rate per annum equal
to the Base Rate plus 2% per annum, and each Bank's payment to
the Issuing Bank pursuant to subsection 3.03(d) shall be deemed
payment in respect of its participation in such L/C Borrowing and
shall constitute an L/C Advance from such Bank in satisfaction of
its participation obligation under this Section 3.03.

                  (f)      Each Bank's obligation in accordance with this
Agreement to make the Loans or L/C Advances, as contemplated by
this Section 3.03, as a result of a drawing under a Letter of
Credit, shall be absolute and unconditional and without recourse
to the Issuing Bank and shall not be affected by any
circumstance, including (i) any set-off, counterclaim,
recoupment, defense or other right which such Bank may have
against the Issuing Bank, the Company or any other Person for any
reason whatsoever; (ii) the occurrence or continuance of a
Default, an Event of Default or a Material Adverse Effect; or
(iii) any other circumstance, happening or event whatsoever,
whether or not similar to any of the foregoing; provided,
however, that each Bank's obligation to make Loans under this
Section 3.03 is subject to the conditions set forth in Section
5.02.

         3.04  Repayment of Participations.

                  (a)      Upon (and only upon) receipt by the Agent for the
account of the Issuing Bank of immediately available funds from
the Company (i) in reimbursement of any payment made by the
Issuing Bank under the Letter of Credit with respect to which any
Bank has paid the Agent for the account of the Issuing Bank for
such Bank's participation in the Letter of Credit pursuant to
Section 3.03 or (ii) in payment of interest thereon, the Agent
will pay to each Bank, in the same funds as those received by the
Agent for the account of the Issuing Bank, the amount of such
Bank's Pro Rata Share of such funds, and the Issuing Bank shall
receive the amount of the Pro Rata Share of such funds of any
Bank that did not so pay the Agent for the account of the Issuing
Bank.

                  (b)      If the Agent or the Issuing Bank is required at
any time to return to the Company, or to a trustee, receiver,
liquidator, custodian, or any official in any Insolvency
Proceeding, any portion of the payments made by the Company to
the Agent for the account of the Issuing Bank pursuant to
subsection 3.04(a) in reimbursement of a payment made under the
Letter of Credit or interest or fee thereon, each Bank shall, on
demand of the Agent, forthwith return to the Agent or the Issuing

 
                                                        46

Bank the amount of its Pro Rata Share of any amounts so returned
by the Agent or the Issuing Bank plus interest thereon from the
date such demand is made to the date such amounts are returned by
such Bank to the Agent or the Issuing Bank, at a rate per annum
equal to the Federal Funds Rate in effect from time to time.

         3.05  Role of the Issuing Bank.

                  (a)      Each Bank and the Company agree that, in paying
any drawing under a Letter of Credit, the Issuing Bank shall not
have any responsibility to obtain any document (other than any
sight draft and certificates expressly required by the Letter of
Credit) or to ascertain or inquire as to the validity or accuracy
of any such document or the authority of the Person executing or
delivering any such document.

                  (b)      No Agent-Related Person nor any of the respective
correspondents, participants or assignees of the Issuing Bank
shall be liable to any Bank for: (i) any action taken or omitted
in connection herewith at the request or with the approval of the
Banks (including the Majority Banks, as applicable); (ii) any
action taken or omitted in the absence of gross negligence or
willful misconduct; or (iii) the due execution, effectiveness,
validity or enforceability of any L/C-Related Document.

                  (c)      The Company hereby assumes all risks of the acts
or omissions of any beneficiary or transferee with respect to its
use of any Letter of Credit; provided, however, that this
assumption is not intended to, and shall not, preclude the
Company's pursuing such rights and remedies as it may have
against the beneficiary or transferee at law or under any other
agreement.  No Agent-Related Person, nor any of the respective
correspondents, participants or assignees of the Issuing Bank,
shall be liable or responsible for any of the matters described
in clauses (i) through (vii) of Section 3.06; provided, however,
anything in such clauses to the contrary notwithstanding, that
the Company may have a claim against the Issuing Bank, and the
Issuing Bank may be liable to the Company, to the extent, but
only to the extent, of any direct, as opposed to consequential or
exemplary, damages suffered by the Company which the Company
proves were caused by the Issuing Bank's willful misconduct or
gross negligence or the Issuing Bank's willful failure to pay
under any Letter of Credit after the presentation to it by the
beneficiary of a sight draft and certificate(s) strictly
complying with the terms and conditions of a Letter of Credit. In
furtherance and not in limitation of the foregoing: (i) the
Issuing Bank may accept documents that appear on their face to be
in order, without responsibility for further investigation,

 
                                                        47


regardless of any notice or information to the contrary; and
(ii) the Issuing Bank shall not be responsible for the validity
or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign a Letter of Credit or the rights
or benefits thereunder or proceeds thereof, in whole or in part,
which may prove to be invalid or ineffective for any reason.

         3.06  Obligations Absolute.  The obligations of the Company
under this Agreement and any L/C-Related Document to reimburse
the Issuing Bank for a drawing under a Letter of Credit, and to
repay any L/C Borrowing and any drawing under a Letter of Credit
converted into Revolving Loans, shall be unconditional and
irrevocable, and shall be paid strictly in accordance with the
terms of this Agreement and each such other L/C-Related Document
under all circumstances, including the following:

                           (i) any lack of validity or enforceability of this
         Agreement or any L/C-Related Document;

                           (ii) any change in the time, manner or place of
         payment of, or in any other term of, all or any of the
         obligations of the Company in respect of any Letter of
         Credit or any other amendment or waiver of or any consent to
         departure from all or any of the L/C-Related Documents;

                           (iii) the existence of any claim, set-off, defense
         or other right that the Company may have at any time against
         any beneficiary or any transferee of any Letter of Credit
         (or any Person for whom any such beneficiary or any such
         transferee may be acting), the Issuing Bank or any other
         Person, whether in connection with this Agreement, the
         transactions contemplated hereby or by the L/C-Related
         Documents or any unrelated transaction;

                           (iv) any draft, demand, certificate or other
         document presented under any Letter of Credit proving to be
         forged, fraudulent, invalid or insufficient in any respect
         or any statement therein being untrue or inaccurate in any
         respect; or any loss or delay in the transmission or
         otherwise of any document required in order to make a
         drawing under any Letter of Credit;

                           (v) any payment by the Issuing Bank under any
         Letter of Credit against presentation of a draft or
         certificate that does not strictly comply with the terms of
         any Letter of Credit; or any payment made by the Issuing
         Bank under any Letter of Credit to any Person purporting to
         be a trustee in bankruptcy, debtor-in-possession, assignee

 
                                                        48

        for the benefit of creditors, liquidator, receiver or other
         representative of or successor to any beneficiary or any
         transferee of any Letter of Credit, including any arising in
         connection with any Insolvency Proceeding;

                           (vi) any exchange, release or non-perfection of
         any collateral, or any release or amendment or waiver of or
         consent to departure from any other guarantee, for all or
         any of the obligations of the Company in respect of any
         Letter of Credit; or

                           (vii) any other circumstance or happening
         whatsoever, whether or not similar to any of the foregoing,
         including any other circumstance that might otherwise
         constitute a defense available to, or a discharge of, the
         Company or a guarantor.

         3.07  Cash Collateral Pledge.  Upon (i) the request of the
Agent, (A) if the Issuing Bank has honored any full or partial
drawing request on any Letter of Credit and such drawing has
resulted in an L/C Borrowing hereunder, or (B) if, as of the
Revolving Termination Date, any Letters of Credit may for any
reason remain outstanding and partially or wholly undrawn, or
(ii) the occurrence of the circumstances described in Section
2.07 requiring the Company to Cash Collateralize Letters of
Credit, then, the Company shall immediately Cash Collateralize
the L/C Obligations in an amount equal to such L/C Obligations.

         3.08  Letter of Credit Fees.

                  (a)      The Company shall pay to the Agent for the account
of each of the Banks a letter of credit fee on the average daily
maximum amount available to be drawn of the outstanding Letters
of Credit, computed on a quarterly basis in arrears on the last
Business Day of each calendar quarter based upon Letters of
Credit outstanding for that quarter as calculated by the Agent,
at a rate per annum equal to the Applicable Letter of Credit Fee
Rate.  Such letter of credit fees shall be due and payable
quarterly in arrears on the last Business Day of each calendar
quarter during which Letters of Credit are outstanding,
commencing on December 31, 1998, through the Revolving
Termination Date (or such later date upon which the outstanding
Letters of Credit shall expire), with the final payment to be
made on the Revolving Termination Date (or such later expiration
date).

                  (b)      The Company shall pay to the Issuing Bank, for its
sole account, a letter of credit fronting fee for each Letter of

 
                                                        49


Credit Issued by the Issuing Bank equal to .125% of the face
amount (or increased face amount, as the case may be) of such
Letter of Credit.  Such Letter of Credit fronting fee shall be
due and payable on each date of Issuance of a Letter of Credit.

                  (c)      The Company shall pay to the Issuing Bank, for its
sole account, from time to time on demand the normal issuance,
presentation, amendment and other processing fees, and other
standard costs and charges, of the Issuing Bank relating to
letters of credit as from time to time in effect.

         3.09  Uniform Customs and Practice.  The Uniform Customs and
Practice for Documentary Credits as published by the
International Chamber of Commerce most recently at the time of
issuance of any Letter of Credit shall (unless otherwise
expressly provided in the Letters of Credit) apply to the Letters
of Credit.


                                                    ARTICLE IV
                                      TAXES, YIELD PROTECTION AND ILLEGALITY

         4.01  Taxes.

                  (a)      Any and all payments by the Company to each Bank
or the Agent under this Agreement and any other Loan Document
shall be made free and clear of, and without deduction or
withholding for, any Taxes.  In addition, the Company shall pay
all Other Taxes.

                  (b)      If the Company shall be required by law to deduct
or withhold any Taxes or Other Taxes from or in respect of any
sum payable hereunder to any Bank or the Agent, then:

                           (i) the sum payable shall be increased as
         necessary so that, after making all required deductions and
         withholdings (including deductions and withholdings
         applicable to additional sums payable under this Section),
         such Bank or the Agent, as the case may be, receives and
         retains an amount equal to the sum it would have received
         and retained had no such deductions or withholdings been
         made;

                           (ii) the Company shall make such deductions and
         withholdings;


 
                                                        50

                          (iii) the Company shall pay the full amount
         deducted or withheld to the relevant taxing authority or
         other authority in accordance with applicable law; and

                           (iv) the Company shall also pay to each Bank or
         the Agent for the account of such Bank, at the time interest
         is paid, Further Taxes in the amount that the respective
         Bank specifies as necessary to preserve the after-tax yield
         the Bank would have received if such Taxes, Other Taxes or
         Further Taxes had not been imposed;

provided, that the foregoing obligation of the Company to pay
such additional amounts shall not apply

                                    (A)     to any payment to any Bank that is
         subject to deduction for or withholding for taxes pursuant
         to the Code, unless, as of the Closing Date or the date it
         becomes a Bank pursuant to Section 11.08, such Bank is
         entitled to submit a Form 1001 (relating to such Bank and
         entitling it to a complete exemption from withholding on all
         interest to be received by it under this Agreement) or a
         Form 4224 (relating to all interest to be received by such
         Bank under this Agreement in respect of the Loans) (and, in
         that regard, each such Bank shall deliver to the
         Administrative Agent and the Company the documentation
         required by Section 10.10), or

     (B) to any taxes  imposed  solely by reason of the  failure of such Bank to
comply  with  applicable  certification,  information,  documentation  or  other
reporting  requirements  concerning  the  nationality,  residence,  identity  or
connections  with the United States of such Bank if such  compliance is required
by statute or regulations  of the United States as a  precondition  to relief or
exemption from such Taxes.

                  (c)      The Company agrees to indemnify and hold harmless
each Bank and the Agent for the full amount of (i) Taxes,
(ii) Other Taxes, and (iii) Further Taxes in the amount that the
respective Bank specifies as necessary to preserve the after-tax
yield the Bank would have received if such Taxes, Other Taxes or
Further Taxes had not been imposed, and any liability (including
penalties, interest, additions to tax and expenses) arising
therefrom or with respect thereto, whether or not such Taxes,
Other Taxes or Further Taxes were correctly or legally asserted.
Payment under this indemnification shall be made within 30 days
after the date the Bank or the Agent makes written demand
therefor.

 
                                                        51


                  (d)      Within 30 days after the date of any payment by
the Company of Taxes, Other Taxes or Further Taxes, the Company
shall furnish to each Bank or the Agent the original or a
certified copy of a receipt evidencing payment thereof, or other
evidence of payment satisfactory to such Bank or the Agent.

                  (e)      If the Company is required to pay any amount to
any Bank or the Agent pursuant to subsection (b) or (c) of this
Section, then such Bank shall use reasonable efforts (consistent
with legal and regulatory restrictions) to change the
jurisdiction of its Lending Office so as to eliminate any such
additional payment by the Company which may thereafter accrue, if
such change in the sole judgment of such Bank is not otherwise
disadvantageous to such Bank.

         4.02  Illegality.

                  (a)      If any Bank determines that the introduction of
any Requirement of Law, or any change in any Requirement of Law,
or in the interpretation or administration of any Requirement of
Law, has made it unlawful, or that any central bank or other
Governmental Authority has asserted that it is unlawful, for any
Bank or its applicable Lending Office to make LIBOR Rate Loans,
then, on notice thereof by the Bank to the Company through the
Agent, any obligation of that Bank to make LIBOR Rate Loans shall
be suspended until the Bank notifies the Agent and the Company
that the circumstances giving rise to such determination no
longer exist.

                  (b)      If a Bank determines that it is unlawful to
maintain any LIBOR Rate Loan, the Company shall, upon its receipt
of notice of such fact and demand from such Bank (with a copy to
the Agent), prepay in full such LIBOR Rate Loans of that Bank
then outstanding, together with interest accrued thereon and
amounts required under Section 4.04, either on the last day of
the Interest Period thereof, if the Bank may lawfully continue to
maintain such LIBOR Rate Loans to such day, or immediately, if
the Bank may not lawfully continue to maintain such LIBOR Rate
Loan.  If the Company is required to so prepay any LIBOR Rate
Loan, then concurrently with such prepayment, the Company shall
borrow from the affected Bank, in the amount of such repayment, a
Base Rate Loan.

                  (c)      If the obligation of any Bank to make or maintain
LIBOR Rate Loans has been so terminated or suspended, the Company
may elect, by giving notice to the Bank through the Agent that
all Loans which would otherwise be made by the Bank as LIBOR Rate
Loans shall be instead Base Rate Loans.

 
                                                        52

        4.03  Increased Costs and Reduction of Return.

                  (a)      If any Bank determines that, due to either (i) the
introduction of or any change in or in the interpretation by any
Governmental Authority of any law or regulation or (ii) the
compliance by that Bank with any guideline or request from any
central bank or other Governmental Authority (whether or not
having the force of law), there shall be any increase in the cost
to such Bank of agreeing to make or making, funding or
maintaining any LIBOR Rate Loans or participating in Letters of
Credit, or, in the case of the Issuing Bank, any increase in the
cost to the Issuing Bank of agreeing to issue, issuing or
maintaining any Letter of Credit or of agreeing to make or
making, funding or maintaining any unpaid drawing under any
Letter of Credit, then the Company shall be liable for, and shall
from time to time, upon demand (with a copy of such demand to be
sent to the Agent), pay to the Agent for the account of such
Bank, additional amounts as are sufficient to compensate such
Bank for such increased costs.

                  (b)      If any Bank shall have determined that (i) the
introduction of any Capital Adequacy Regulation, (ii) any change
in any Capital Adequacy Regulation, (iii) any change in the
interpretation or administration of any Capital Adequacy
Regulation by any central bank or other Governmental Authority
charged with the interpretation or administration thereof, or
(iv) compliance by the Bank (or its Lending Office) or any
corporation controlling the Bank with any Capital Adequacy
Regulation, affects or would affect the amount of capital
required or expected to be maintained by the Bank or any
corporation controlling the Bank and (taking into consideration
such Bank's or such corporation's policies with respect to
capital adequacy and such Bank's desired return on capital)
determines that the amount of such capital is increased as a
consequence of its Commitment, loans, credits or obligations
under this Agreement, then, upon demand of such Bank to the
Company through the Agent, the Company shall pay to the Bank,
from time to time as specified by the Bank, additional amounts
sufficient to compensate the Bank for such increase.

         4.04  Funding Losses.  The Company shall reimburse each Bank
and hold each Bank harmless from any loss or expense which the
Bank may sustain or incur as a consequence of:

                  (a)      the failure of the Company to make on a timely
basis any payment of principal of any LIBOR Rate Loan;


 
                                                        53


                  (b)      the failure of the Company to borrow, continue or
convert a Loan after the Company has given (or is deemed to have
given) a Notice of Borrowing or a Notice of Conversion/
Continuation;

                  (c)      the failure of the Company to make any prepayment
in accordance with any notice delivered under Section 2.06;

                  (d)      the prepayment (including pursuant to Section
2.07) or other payment (including after acceleration thereof) of
a LIBOR Rate Loan on a day that is not the last day of the
relevant Interest Period; or

                  (e)      the automatic conversion under Section 2.04 of any
LIBOR Rate Loan into a Base Rate Loan on a day that is not the
last day of the relevant Interest Period;

including any such loss or expense arising from the liquidation
or reemployment of funds obtained by it to maintain its LIBOR
Rate Loans or from fees payable to terminate the deposits from
which such funds were obtained.  For purposes of calculating
amounts payable by the Company to the Banks under this Section
and under subsection 4.03(a), each LIBOR Rate Loan made by a Bank
(and each related reserve, special deposit or similar
requirement) shall be conclusively deemed to have been funded at
the LIBOR used in determining the LIBOR Rate for such LIBOR Rate
Loan by a matching deposit or other borrowing in the interbank
eurodollar market for a comparable amount and for a comparable
period, whether or not such LIBOR Rate Loan is in fact so funded.

         4.05  Inability to Determine Rates.  If the Agent determines
that for any reason adequate and reasonable means do not exist
for determining the LIBOR Rate for any requested Interest Period
with respect to a proposed LIBOR Rate Loan, or that the LIBOR
Rate applicable pursuant to subsection 2.09(a) for any requested
Interest Period with respect to a proposed LIBOR Rate Loan does
not adequately and fairly reflect the cost to the Banks of
funding such Loan, the Agent will promptly so notify the Company
and each Bank.  Thereafter, the obligation of the Banks to make
or maintain LIBOR Rate Loans hereunder shall be suspended until
the Agent revokes such notice in writing.  Upon receipt of such
notice, the Company may revoke any Notice of Borrowing or Notice
of Conversion/Continuation then submitted by it.  If the Company
does not revoke such Notice, the Banks shall make, convert or
continue the Loans, as proposed by the Company, in the amount
specified in the applicable notice submitted by the Company, but
such Loans shall be made, converted or continued as Base Rate
Loans instead of LIBOR Rate Loans.

 
                                                        54

        4.06  Certificates of Banks.  Any Bank claiming
reimbursement or compensation under this Article IV shall deliver
to the Company (with a copy to the Agent) a certificate setting
forth in reasonable detail the amount payable to the Bank
hereunder and the reasons therefor and such certificate shall be
conclusive and binding on the Company in the absence of manifest
error.

         4.07  Substitution of Banks.  If the Company shall receive
notice from any Bank that LIBOR Rate Loans are no longer
available from such Bank pursuant to Section 4.02 or that amounts
are due to such Bank pursuant to Section 4.01 or 4.03, the
Company may (but subject in any such case to the payments
required by Section 4.04), upon at least five Business Days'
prior written or telecopier notice to such Bank and the Agent,
but not more than 90 days after receipt of written notice from
such Bank, identify to the Agent a lending institution acceptable
to the Company and the Agent, which will purchase the
Commitments, the amount of outstanding Loans and any
participations in Letters of Credit from the Bank providing such
notice, and such Bank shall thereupon assign its Commitment, any
Loans owing to such Bank, any participations in Letters of Credit
and the Notes held by such Bank to such replacement lending
institution pursuant to Section 11.08.

         4.08  Survival.  The agreements and obligations of the
Company in this Article IV shall survive the payment of all other
Obligations.


                                                     ARTICLE V

                  (d)      is in compliance with all Requirements of Law,
except for such instances of non-compliance as would not have,

or performance by, or enforcement against, the Company or any of
its Subsidiaries of the Agreement, the Pledge Agreements or any

                           (i)      the pledge by the Company and the
         Pledgor Subsidiaries of any Collateral pursuant to the
         Pledge Agreements or the execution, delivery, and
         performance of the Pledge Agreements by the Company and
         the Pledgor Subsidiaries; and


 
                                                        61


                           (ii)     the exercise by the Agent of the voting
         or other rights provided for in the Pledge Agreements,

         6.04  Binding Effect.  This Agreement, the Pledge Agreements
and each other Loan Document to which the Company or any Pledgor

obligations of the Company or such Pledgor Subsidiary (as the

        6.06  No Default.  No Default or Event of Default exists or
would result from the incurring of any Obligations by the Company
or any of its Subsidiaries or from the grant or perfection of the
Liens of the Agent and the Banks on the Collateral.  As of the
Closing Date, neither the Company nor any Subsidiary is in
default under or with respect to any Contractual Obligation in
any respect which, individually or together with all such
defaults, could reasonably be expected to have a Material Adverse
Effect, or that would, if such default had occurred after the
Closing Date, create an Event of Default under subsection
9.01(e).

         6.07  Compliance with Laws and ERISA.

                  (a)      Except as set forth on Schedule 6.03, the Company
and its Subsidiaries are in compliance with the requirements of
all applicable laws, rules, regulations and orders of every
governmental authority, the non-compliance with which might
materially adversely affect the business, properties, assets,
operations or condition (financial or otherwise) of the Company
or the value of the Collateral or the worth of the Collateral as
collateral security.

                  (b)      Each Plan is in compliance in all material
respects with the applicable provisions of ERISA, the Code and
other federal or state law.  Each Plan which is intended to
qualify under Section 401(a) of the Code has received a favorable
determination letter from the IRS and to the best knowledge of
the Company, nothing has occurred which would cause the loss of
such qualification.  The Company and each ERISA Affiliate has
made all required contributions to any Plan subject to Section
412 of the Code, and no application for a funding waiver or an
extension of any amortization period pursuant to Section 412 of
the Code has been made with respect to any Plan.

                  (c)      There are no pending (and served) or, to the best
knowledge of Company, otherwise pending or threatened claims,
actions or lawsuits, or action by any Governmental Authority,
with respect to any Plan which has resulted or could reasonably
be expected to result in a Material Adverse Effect.  There has
been no prohibited transaction or violation of the fiduciary
responsibility rules with respect to any Plan which has resulted
or could reasonably be expected to result in a Material Adverse
Effect.

                  (d)      (i) No ERISA Event has occurred or is reasonably
expected to occur;


 
                                                        63


                           (ii) no Pension Plan has any Unfunded Pension
         Liability;

                           (iii) neither the Company nor any ERISA
         Affiliate has incurred, or reasonably expects to incur,
         any liability under Title IV of ERISA with respect to
         any Pension Plan (other than premiums due and not
         delinquent under Section 4007 of ERISA);

                           (iv) neither the Company nor any ERISA
         Affiliate has incurred, or reasonably expects to incur,
         any liability (and no event has occurred which, with
         the giving of notice under Section 4219 of ERISA, would
         result in such liability) under Section 4201 or 4243 of
         ERISA with respect to a Multiemployer Plan; and

                           (v) neither the Company nor any ERISA
         Affiliate has engaged in a transaction that could be
         subject to Section 4069 or 4212(c) of ERISA.

         6.08  Use of Proceeds; Margin Regulations.  The proceeds of
the Loans are to be used solely for the purposes set forth in and
permitted by Section 7.12 and Section 8.07. Neither the Company
nor any Subsidiary is generally engaged in the business of
purchasing or selling Margin Stock or extending credit for the
purpose of purchasing or carrying Margin Stock.

         6.09  Title to Property and Collateral; No Liens.  The
Company and each Subsidiary have good record and marketable title
in fee simple to, or valid leasehold interests in, all real
property necessary or used in the ordinary conduct of their
respective businesses, except for such defects in title as could
not, individually or in the aggregate, have a Material Adverse
Effect.  The Company and the Pledgor Subsidiaries are the legal
and beneficial owners of, and have good and marketable title to
(and have full right and authority to pledge, hypothecate,
mortgage and deliver) all the Collateral that is subject to their
respective Pledge Agreements.  As of the Closing Date, all the
Collateral and other property of the Company and its Subsidiaries
are subject to no Liens, other than Permitted Liens.  Even after
the Closing Date, the Collateral shall continue not to be subject
to any Liens, other than Permitted Liens.

         6.10  As to Pledged Shares.  Except as disclosed in Schedule
6.10, all Pledged Shares are duly authorized and validly issued,
fully paid, and non-assessable, and constitute all of the issued
and outstanding shares of capital stock of the Subsidiaries whose
shares have been pledged by the Company and the Pledgor

 
                                                        64

Subsidiaries under the Pledge Agreements.  Other than the Pledged
Shares, no Subsidiary whose shares have been pledged under the
Pledge Agreements has outstanding any capital stock or other
securities convertible into or exchangeable for any of its
capital stock, nor will it have outstanding any rights to
subscribe for or to purchase, or any warrants or options for the
purchase of, or any agreements (contingent or otherwise)
providing for the issuance of, or any calls, commitments or
claims of any character relating to, any of its capital stock or
any securities convertible into or exchangeable for any of its
capital stock.

         6.11  Taxes.  The Company and its Subsidiaries have filed
all Federal and other material tax returns and reports required
to be filed, and have paid all Federal and other material taxes,
assessments, fees and other governmental charges levied or
imposed upon them or their properties, income or assets otherwise
due and payable, except those which are being contested in good
faith by appropriate proceedings and for which adequate reserves
have been provided in accordance with GAAP. There is no proposed
tax assessment against the Company or any Subsidiary that would,
if made, have a Material Adverse Effect.

         and Contingent Obligations;

         except to the extent that departures from the

         6.25  Year 2000 Representation.  On the basis of a
comprehensive review and assessment of the Company's and its
Subsidiaries' systems and equipment and inquiry made of the
Company's and its Subsidiaries' material suppliers, vendors and
customers, the Company reasonably believes that the "Year 2000
problem" (that is, the inability of computers, as well as
embedded microchips in non-computing devices, to perform properly
date-sensitive functions with respect to certain dates prior to
and after December 31, 1999), including costs of remediation,
will not result in a Material Adverse Effect.  The Company and
its Subsidiaries have developed feasible contingency plans
adequately to ensure uninterrupted and unimpaired business
operation in the event of failure of their own or a third party's
systems or equipment due to the Year 2000 problem, including
those of vendors, customers, and suppliers, as well as a general
failure of or interruption in its communications and delivery
infrastructure.

Subsidiaries, or (ii) the Company or any of its Subsidiaries to
receive or retain vis-a-vis the transferor any such amounts set
forth in clauses (i)(a), (i)(b) or (i)(c) above, except for
encumbrances or restrictions existing under or by reason of HMO
Regulations and other applicable law.

         8.16  Pledged Shares.  The Company shall, and shall cause
each of its Subsidiaries to, pledge to the Agent, for the benefit
of the Banks, all of the shares of capital stock of each of their
respective Subsidiaries (other than the shares of Excluded
Subsidiaries) from time to time pursuant to a Pledge Agreement.

         8.17  Acquisitions.  The Company will not, nor will it
permit any of its Subsidiaries to, make any Acquisition unless:

                      (i) immediately before and after giving effect
         to the consummation of each Acquisition, no Default has
         occurred and is continuing or will exist;

                      (ii) for each such Acquisition involving the
         purchase of a majority of the stock of another party,
         the prior, effective written consent or approval to
         such Acquisition of the board of directors or
         equivalent governing body of the other party or parties
         has been obtained;

                      (iii) the aggregate value of the cash or other

Company.


                                                    ARTICLE IX

to cause such Indebtedness to be declared to be due and payable

                                                        89


                  (o)      Adverse Change.  There occurs a Material Adverse
Effect; or

                  (p)      Invalidity of Subordination Provisions.  The
subordination provisions of the Convertible Debt is for any
reason revoked or invalidated, or otherwise cease to be in full

reasonable likelihood of success) the validity or enforceability
thereof or denies that it has any further liability or obligation
thereunder, or the Indebtedness hereunder is for any reason
subordinated or does not have the priority contemplated by this
Agreement or such subordination provisions.

         9.02  Remedies.  If any Event of Default occurs, the Agent
shall, at the request of, or may, with the consent of, the
Majority Banks,

                  (a)      declare the commitment of each Bank to make Loans
and any obligation of the Issuing Bank to Issue Letters of Credit
to be terminated, whereupon such commitments and obligation shall
be terminated;

                  (b)      declare an amount equal to the maximum aggregate
amount that is or at any time thereafter may become available for
drawing under any outstanding Letters of Credit (whether or not

such time to present, the drafts or other documents required to
draw under such Letters of Credit) to be immediately due and
payable, and declare the unpaid principal amount of all
outstanding Loans, all interest accrued and unpaid thereon, and
all other amounts owing or payable hereunder or under any other
Loan Document to be immediately due and payable, without
presentment, demand, protest or other notice of any kind, all of
which are hereby expressly waived by the Company; and

                  (c)      exercise on behalf of itself and the Banks all
rights and remedies available to it and the Banks under the Loan

provided, however, that upon the occurrence of any event

of clause (i) of subsection (g) upon the expiration of the 60-day
period mentioned therein), the obligation of each Bank to make
Loans and any obligation of the Issuing Bank to Issue Letters of
Credit shall automatically terminate and the unpaid principal
amount of all outstanding Loans and all interest and other
amounts as aforesaid shall automatically become due and payable
without further act of the Agent, the Issuing Bank or any Bank.

 
                                                        90

NOTWITHSTANDING THE FOREGOING, THE AGENT AND THE BANKS EXPRESSLY
ACKNOWLEDGE AND AGREE THAT ANY TRANSFER OF THE PLEDGED SHARES, OR
ANY EXERCISE OF CONTROL WITH RESPECT THERETO, IS SUBJECT TO, AND
SHALL BE EFFECTED SOLELY IN COMPLIANCE WITH, APPLICABLE
REGULATORY REQUIREMENTS; PROVIDED THAT THIS ACKNOWLEDGMENT AND
AGREEMENT IS MADE SOLELY FOR THE BENEFIT OF APPLICABLE
GOVERNMENTAL AND REGULATORY AUTHORITIES AND SHALL NOT BE
CONSTRUED AS A COVENANT AS BETWEEN THE AGENT AND THE BANKS, ON
THE ONE HAND, AND THE COMPANY OR ANY OF ITS SUBSIDIARIES, ON THE
OTHER HAND.

         9.03  Rights Not Exclusive.  The rights provided for in this
Agreement and the other Loan Documents are cumulative and are not
exclusive of any other rights, powers, privileges or remedies
provided by law or in equity, or under any other instrument,
document or agreement now existing or hereafter arising.


                                                     ARTICLE X
                                                     THE AGENT

         10.01  Appointment and Authorization; "Agent".

                  (a)      Each Bank hereby irrevocably (subject to Section
10.09) appoints, designates and authorizes the Agent to take such
action on its behalf under the provisions of this Agreement and
each other Loan Document and to exercise such powers and perform
such duties as are expressly delegated to it by the terms of this
Agreement or any other Loan Document, together with such powers
as are reasonably incidental thereto.  Notwithstanding any
provision to the contrary contained elsewhere in this Agreement
or in any other Loan Document, the Agent shall not have any
duties or responsibilities, except those expressly set forth
herein, nor shall the Agent have or be deemed to have any
fiduciary relationship with any Bank, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities
shall be read into this Agreement or any other Loan Document or
otherwise exist against the Agent.  Without limiting the
generality of the foregoing sentence, the use of the term "agent"
in this Agreement with reference to the Agent is not intended to
connote any fiduciary or other implied (or express) obligations
arising under agency doctrine of any applicable law. Instead,
such term is used merely as a matter of market custom, and is
intended to create or reflect only an administrative relationship
between independent contracting parties.

                  (b)      The Issuing Bank shall act on behalf of the Banks
with respect to any Letters of Credit Issued by it and the

 
                                                        91


documents associated therewith until such time and except for so
long as the Agent may agree at the request of the Majority
Lenders to act for such Issuing Bank with respect thereto;
provided, however, that the Issuing Bank shall have all of the
benefits and immunities (i) provided to the Agent in this Article
X with respect to any acts taken or omissions suffered by the
Issuing Bank in connection with Letters of Credit Issued by it or
proposed to be Issued by it and the application and agreements
for letters of credit pertaining to the Letters of Credit as
fully as if the term "Agent", as used in this Article X, included
the Issuing Bank with respect to such acts or omissions, and
(ii) as additionally provided in this Agreement with respect to
the Issuing Bank.

         10.02  Delegation of Duties.  The Agent may execute any of
its duties under this Agreement or any other Loan Document by or
through agents, employees or attorneys-in-fact and shall be
entitled to advice of counsel concerning all matters pertaining
to such duties.  The Agent shall not be responsible for the
negligence or misconduct of any agent or attorney-in-fact that it
selects with reasonable care.

         10.03  Liability of Agent.  None of the Agent-Related
Persons shall (i) be liable for any action taken or omitted to be
taken by any of them under or in connection with this Agreement
or any other Loan Document or the transactions contemplated
hereby (except for its own gross negligence or willful
misconduct), or (ii) be responsible in any manner to any of the
Banks for any recital, statement, representation or warranty made
by the Company or any Subsidiary or Affiliate of the Company, or
any officer thereof, contained in this Agreement or in any other
Loan Document, or in any certificate, report, statement or other
document referred to or provided for in, or received by the Agent
under or in connection with, this Agreement or any other Loan
Document, or the validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Loan
Document, or for any failure of the Company or any other party to
any Loan Document to perform its obligations hereunder or
thereunder.  No Agent-Related Person shall be under any
obligation to any Bank to ascertain or to inquire as to the
observance or performance of any of the agreements contained in,
or conditions of, this Agreement or any other Loan Document, or
to inspect the properties, books or records of the Company or any
of the Company's Subsidiaries or Affiliates.

         10.04  Reliance by Agent.


 
                                                        92

                 (a)      The Agent shall be entitled to rely, and shall be
fully protected in relying, upon any writing, resolution, notice,
consent, certificate, affidavit, letter, telegram, facsimile,
telex or telephone message, statement or other document or
conversation believed by it to be genuine and correct and to have
been signed, sent or made by the proper Person or Persons, and
upon advice and statements of legal counsel (including counsel to
the Company), independent accountants and other experts selected
by the Agent. The Agent shall be fully justified in failing or
refusing to take any action under this Agreement or any other
Loan Document unless it shall first receive such advice or
concurrence of the Majority Banks as it deems appropriate and, if
it so requests, it shall first be indemnified to its satisfaction
by the Banks against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any
such action.  The Agent shall in all cases be fully protected in
acting, or in refraining from acting, under this Agreement or any
other Loan Document in accordance with a request or consent of
the Majority Banks and such request and any action taken or
failure to act pursuant thereto shall be binding upon all of the
Banks.

                  (b)      For purposes of determining compliance with the
conditions specified in Section 5.01, each Bank that has executed
this Agreement shall be deemed to have consented to, approved or
accepted or to be satisfied with, each document or other matter
either sent by the Agent to such Bank for consent, approval,
acceptance or satisfaction, or required thereunder to be
consented to or approved by or acceptable or satisfactory to the
Bank.

         10.05  Notice of Default.  The Agent shall not be deemed to
have knowledge or notice of the occurrence of any Default or
Event of Default, except with respect to defaults in the payment
of principal, interest and fees required to be paid to the Agent
for the account of the Banks, unless the Agent shall have
received written notice from a Bank or the Company referring to
this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default".  The Agent
will notify the Banks of its receipt of any such notice.  The
Agent shall take such action with respect to such Default or
Event of Default as may be requested by the Majority Banks in
accordance with Article IX; provided, however, that unless and
until the Agent has received any such request, the Agent may (but
shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of
Default as it shall deem advisable or in the best interest of the
Banks.

 
                                                        93


         10.06  Credit Decision.  Each Bank acknowledges that none of
the Agent-Related Persons has made any representation or warranty
to it, and that no act by the Agent hereinafter taken, including
any review of the affairs of the Company and its Subsidiaries,
shall be deemed to constitute any representation or warranty by
any Agent-Related Person to any Bank.  Each Bank represents to
the Agent that it has, independently and without reliance upon
any Agent-Related Person and based on such documents and
information as it has deemed appropriate, made its own appraisal
of and investigation into the business, prospects, operations,
property, financial and other condition and creditworthiness of
the Company and its Subsidiaries, and all applicable bank
regulatory laws relating to the transactions contemplated hereby,
and made its own decision to enter into this Agreement and to
extend credit to the Company hereunder.  Each Bank also
represents that it will, independently and without reliance upon
any Agent-Related Person and based on such documents and
information as it shall deem appropriate at the time, continue to
make its own credit analysis, appraisals and decisions in taking
or not taking action under this Agreement and the other Loan
Documents, and to make such investigations as it deems necessary
to inform itself as to the business, prospects, operations,
property, financial and other condition and creditworthiness of
the Company. Except for notices, reports and other documents
expressly herein required to be furnished to the Banks by the
Agent, the Agent shall not have any duty or responsibility to
provide any Bank with any credit or other information concerning
the business, prospects, operations, property, financial and
other condition or creditworthiness of the Company which may come
into the possession of any of the Agent-Related Persons.

         10.07  Indemnification of Agent.  Whether or not the
transactions contemplated hereby are consummated, the Banks shall
indemnify upon demand the Agent-Related Persons (to the extent
not reimbursed by or on behalf of the Company and without
limiting the obligation of the Company to do so), pro rata, from
and against any and all Indemnified Liabilities; provided,
however, that no Bank shall be liable for the payment to the
Agent-Related Persons of any portion of such Indemnified
Liabilities resulting solely from such Person's gross negligence
or willful misconduct. Without limitation of the foregoing, each
Bank shall reimburse the Agent upon demand for its ratable share
of any costs or out-of-pocket expenses (including Attorney Costs)
incurred by the Agent in connection with the preparation,
execution, delivery, administration, modification, amendment or
enforcement (whether through negotiations, legal proceedings or
otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document,

 
                                                        94

or any document contemplated by or referred to herein, to the
extent that the Agent is not reimbursed for such expenses by or
on behalf of the Company.  The undertaking in this Section shall
survive the payment of all Obligations hereunder and the
resignation or replacement of the Agent.

         10.08  Agent in Individual Capacity.  BofA and its
Affiliates may make loans to, issue letters of credit for the
account of, accept deposits from, acquire equity interests in and
generally engage in any kind of banking, trust, financial
advisory, underwriting or other business with the Company and its
Subsidiaries and Affiliates as though BofA were not the Agent or
the Issuing Bank hereunder and without notice to or consent of
the Banks. The Banks acknowledge that, pursuant to such
activities, BofA or its Affiliates may receive information
regarding the Company or its Affiliates (including information
that may be subject to confidentiality obligations in favor of
the Company or such Subsidiary) and acknowledge that the Agent
shall be under no obligation to provide such information to them.
With respect to its Loans, BofA shall have the same rights and
powers under this Agreement as any other Bank and may exercise
the same as though it were not the Agent or the Issuing Bank.

         10.09  Successor Agent.  The Agent may, and at the request
of the Majority Banks shall, resign as Agent upon 30 days' notice
to the Banks.  If the Agent resigns under this Agreement, the
Majority Banks shall appoint from among the Banks a successor
agent for the Banks.  If no successor agent is appointed prior to
the effective date of the resignation of the Agent, the Agent may
appoint, after consulting with the Banks and the Company, a
successor agent from among the Banks.  Upon the acceptance of its
appointment as successor agent hereunder, such successor agent
shall succeed to all the rights, powers and duties of the
retiring Agent and the term "Agent" shall mean such successor
agent and the retiring Agent's appointment, powers and duties as
Agent shall be terminated. After any retiring Agent's resignation
hereunder as Agent, the provisions of this Article X and Sections
11.04 and 11.05 shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Agent under this
Agreement.  If no successor agent has accepted appointment as
Agent by the date which is 30 days following a retiring Agent's
notice of resignation, the retiring Agent's resignation shall
nevertheless thereupon become effective and the Banks shall
perform all of the duties of the Agent hereunder until such time,
if any, as the Majority Banks appoint a successor agent as
provided for above.  Notwithstanding the foregoing, however, BofA
may not be removed as the Agent at the request of the Majority
Banks unless BofA shall also simultaneously be replaced as

 
                                                        95


"Issuing Bank" hereunder pursuant to documentation in form and
substance reasonably satisfactory to BofA.

         10.10  Withholding Tax.

                  (a)      If any Bank is a "foreign corporation, partnership
or trust" within the meaning of the Code and such Bank claims
exemption from, or a reduction of, U.S. withholding tax under
Sections 1441 or 1442 of the Code, such Bank agrees with and in
favor of the Agent and the Company, to deliver to the Agent:

                      (i) if such Bank claims an exemption from, or a
         reduction of, withholding tax under a United States tax
         treaty, two properly completed and executed copies of IRS
         Form 1001 before the payment of any interest in the first
         calendar year and before the payment of any interest in each
         third succeeding calendar year during which interest may be
         paid under this Agreement;

                      (ii) if such Bank claims that interest paid under
         this Agreement is exempt from United States withholding tax
         because it is effectively connected with a United States
         trade or business of such Bank, two properly completed and
         executed copies of IRS Form 4224 before the payment of any
         interest is due in the first taxable year of such Bank and
         in each succeeding taxable year of such Bank during which
         interest may be paid under this Agreement; and

                      (iii) such other form or forms as may be required
         under the Code or other laws of the United States as a
         condition to exemption from, or reduction of, United States
         withholding tax.

Such Bank agrees to promptly notify the Agent and the Company of
any change in circumstances which would modify or render invalid
any claimed exemption or reduction.

                  (b)      If any Bank claims exemption from, or reduction
of, withholding tax under a United States tax treaty by providing
IRS Form 1001 and such Bank sells, assigns, grants a
participation in, or otherwise transfers all or part of the
Obligations of the Company to such Bank, such Bank agrees to
notify the Agent of the percentage amount in which it is no
longer the beneficial owner of Obligations of the Company to such
Bank.  To the extent of such percentage amount, the Agent will
treat such Bank's IRS Form 1001 as no longer valid.


 
                                                        96

                 (c)      If any Bank claiming exemption from United States
withholding tax by filing IRS Form 4224 with the Agent sells,
assigns, grants a participation in, or otherwise transfers all or
part of the Obligations of the Company to such Bank, such Bank
agrees to undertake sole responsibility for complying with the
withholding tax requirements imposed by Sections 1441 and 1442 of
the Code.

                  (d)      If any Bank is entitled to a reduction in the
applicable withholding tax, the Agent may withhold from any
interest payment to such Bank an amount equivalent to the
applicable withholding tax after taking into account such
reduction.  However, if the forms or other documentation required
by subsection (a) of this Section are not delivered to the Agent,
then the Agent may withhold from any interest payment to such
Bank not providing such forms or other documentation an amount
equivalent to the applicable withholding tax imposed by Sections
1441 and 1442 of the Code, without reduction.

                  (e)      If the IRS or any other Governmental Authority of
the United States or other jurisdiction asserts a claim that the
Agent or the Company did not properly withhold tax from amounts
paid to or for the account of any Bank (because the appropriate
form was not delivered or was not properly executed, or because
such Bank failed to notify the Agent of a change in circumstances
which rendered the exemption from, or reduction of, withholding
tax ineffective, or for any other reason) such Bank shall
indemnify the Agent and the Company fully for all amounts paid,
directly or indirectly, by the Agent or the Company as tax or
otherwise, including penalties and interest, and including any
taxes imposed by any jurisdiction on the amounts payable to the
Agent under this Section, together with all costs and expenses
(including Attorney Costs). The obligation of the Banks under
this subsection shall survive the payment of all Obligations and
the resignation or replacement of the Agent.

         10.11  Syndication Agent.  The Bank identified on the facing
page or signature pages of this Agreement as the "syndication
agent" shall not have any right, power, obligation, liability,
responsibility or duty under this Agreement other than those
applicable to all Banks as such.  Without limiting the foregoing,
the Bank so identified as the "syndication agent" shall not have
or be deemed to have any fiduciary relationship with any Bank.
Each Bank acknowledges that it has not relied, and will not rely,
on the Bank so identified in deciding to enter into this
Agreement or in taking or not taking any action hereunder.

         11.01  Amendments and Waivers.  No amendment or waiver of
any provision of this Agreement or any other Loan Document, and

                  (e)      amend this Section, or Section 2.14, or any
provision herein providing for consent or other action by all
Banks;

and, provided further, that (i) no amendment, waiver or consent
shall, unless in writing and signed by the Issuing Bank in

be, affect the rights or duties of the Issuing Bank under this
Agreement or any L/C-Related Document relating to any Letter of
Credit Issued or to be Issued by it, (ii) no amendment, waiver or
consent shall, unless in writing and signed by the Agent in
addition to the Majority Banks or all the Banks, as the case may

or any other Loan Document, and (iii) the Fee Letters may be

 
                                                        98

amended, or rights or privileges thereunder waived, in a writing
executed by the parties thereto.

         11.02  Notices.

                  (a)      All notices, requests, consents, approvals,
waivers and other communications shall be in writing (including,
unless the context expressly otherwise provides, by facsimile
transmission, provided that any matter transmitted by the Company
by facsimile (i) shall be immediately confirmed by a telephone
call to the recipient at the number specified on Schedule 11.02,
and (ii) shall be followed promptly by delivery of a hard copy
original thereof) and mailed, faxed or delivered, to the address
or facsimile number specified for notices on Schedule 11.02; or,
as directed to the Company or the Agent, to such other address as
shall be designated by such party in a written notice to the
other parties, and as directed to any other party, at such other
address as shall be designated by such party in a written notice
to the Company and the Agent.

                  (b)      All such notices, requests and communications
shall, when transmitted by overnight delivery, or faxed, be
effective when delivered for overnight (next-day) delivery, or
transmitted in legible form by facsimile machine, respectively,
or if mailed, upon the third Business Day after the date
deposited into the U.S. mail, or if delivered, upon delivery;
except that notices pursuant to Article II, III or X to the Agent
shall not be effective until actually received by the Agent, and
notices pursuant to Article III to the Issuing Bank shall not be
effective until actually received by the Issuing Bank at the
address specified for the "Issuing Bank" on the applicable
signature page hereof.

                  (c)      Any agreement of the Agent and the Banks herein to
receive certain notices by telephone or facsimile is solely for
the convenience and at the request of the Company and the Pledgor
Subsidiaries.  The Agent and the Banks shall be entitled to rely
on the authority of any Person purporting to be a Person
authorized by the Company or any Pledgor Subsidiary to give such
notice and the Agent and the Banks shall not have any liability
to the Company, any Pledgor subsidiary or other Person on account
of any action taken or not taken by the Agent or the Banks in
reliance upon such telephonic or facsimile notice.  The
obligation of the Company to repay the Loans and L/C Obligations
shall not be affected in any way or to any extent by any failure
by the Agent and the Banks to receive written confirmation of any
telephonic or facsimile notice or the receipt by the Agent and
the Banks of a confirmation which is at variance with the terms

 
                                                        99


understood by the Agent and the Banks to be contained in the
telephonic or facsimile notice.

         11.03  No Waiver; Cumulative Remedies.  No failure to
exercise and no delay in exercising, on the part of the Agent or
any Bank, any right, remedy, power or privilege hereunder, shall
operate as a waiver thereof;  nor shall any single or partial
exercise of any right, remedy, power or privilege hereunder
preclude any other or further exercise thereof or the exercise of
any other right, remedy, power or privilege.

         11.04  Costs and Expenses.  The Company shall:

                  (a)      whether or not the transactions contemplated
hereby are consummated, pay or reimburse BofA (including in its
capacity as Agent and Issuing Bank) within five Business Days
after demand (subject to subsection 5.01(e)) for all reasonable
costs and expenses incurred by BofA (including in its capacity as
Agent and Issuing Bank) in connection with the development,
preparation, delivery, administration and execution of, and any
amendment, supplement, waiver or modification to (in each case,
whether or not consummated), this Agreement, any Loan Document
and any other documents prepared in connection herewith or
therewith, and the consummation of the transactions contemplated
hereby and thereby, including reasonable Attorney Costs incurred
by or on behalf of BofA (including in its capacity as Agent and
Issuing Bank) with respect thereto; and

                  (b)      pay or reimburse the Agent and each Bank within
five Business Days after demand (subject to subsection 5.01(e))
for all reasonable costs and expenses (including Attorney Costs)
incurred by them in connection with the enforcement, attempted
enforcement, or preservation of any rights or remedies under this
Agreement or any other Loan Document during the existence of an
Event of Default or after acceleration of the Loans (including in
connection with any "workout" or restructuring regarding the
Loans, and including in any Insolvency Proceeding or appellate
proceeding).

         11.05  Company Indemnification.  Whether or not the
transactions contemplated hereby are consummated, the Company
shall indemnify, defend and hold the Agent-Related Persons, and
each Bank and each of its respective officers, directors,
employees, counsel, agents and attorneys-in-fact (each, an
"Indemnified Person") harmless from and against any and all
liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, charges, expenses and disbursements
(including of experts and agents and Attorney Costs which all

 
                                                        100

shall be paid upon demand by the Agent) of any kind or nature
whatsoever which may at any time (including at any time following
repayment of the Loans, the termination of the Letters of Credit
and the termination, resignation or replacement of the Agent or
replacement of any Bank) be imposed on, incurred by or asserted
against any such Person in any way relating to or arising out of:
this Agreement, the Pledge Agreements or any document
contemplated by or referred to herein; the administration of the
Loan Documents; the custody, preservation, use or operation of or
the sale of, collection from, or other realization upon, any of
the Collateral; the exercise or enforcement of any of the rights
of the Agent under the Pledge Agreements or any other Loan
Document; the failure by the Company to perform or observe any of
the provisions of the Pledge Agreements or any other Loan
Document; the transactions contemplated hereby; or any other
action taken or omitted by any such Person under or in connection
with any of the foregoing, including with respect to any
investigation, litigation or proceeding (including any Insolvency
Proceeding or appellate proceeding) related to or arising out of
this Agreement or the Loans or Letters of Credit or the use of
the proceeds thereof, whether or not any Indemnified Person is a
party thereto (all the foregoing, collectively, the "Indemnified
Liabilities"); provided, that the Company shall have no
obligation hereunder to any Indemnified Person with respect to
Indemnified Liabilities resulting solely from the gross
negligence or willful misconduct of such Indemnified Person. The
agreements in this Section shall survive payment of all other
Obligations.

         11.06  Payments Set Aside.  To the extent that the Company
makes a payment to the Agent or the Banks, or the Agent or the
Banks exercise their right of set-off, and such payment or the
proceeds of such set-off or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside
or required (including pursuant to any settlement entered into by
the Agent or such Bank in its discretion) to be repaid to a
trustee, receiver or any other party, in connection with any
Insolvency Proceeding or otherwise, then (a) to the extent of
such recovery the obligation or part thereof originally intended
to be satisfied shall be revived and continued in full force and
effect as if such payment had not been made or such set-off had
not occurred, and (b) each Bank severally agrees to pay to the
Agent upon demand its pro rata share of any amount so recovered
from or repaid by the Agent.

         11.07  Successors and Assigns.  The provisions of this
Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns,

 
                                                        101


except that the Company may not assign or transfer any of its
rights or obligations under this Agreement without the prior
written consent of the Agent and each Bank.

         11.08  Assignments, Participations, etc.

                  (a)      Any Bank may, with the written consent of the
Company at all times other than during the existence of an Event
of Default and the Agent and the Issuing Bank, which consents
shall not be unreasonably withheld, at any time assign and
delegate to one or more Eligible Assignees (provided that no
written consent of the Company, the Agent or the Issuing Bank
shall be required in connection with any assignment and
delegation by a Bank to an Eligible Assignee that is an Affiliate
of such Bank) (each an "Assignee") all, or any ratable part of
all, of the Loans, the Commitments, the L/C Obligations and the
other rights and obligations of such Bank hereunder, in a minimum
amount of $5,000,000; provided, however, that after giving effect
thereto, such Bank shall either retain a Commitment in a minimum
amount of $5,000,000 or have no ongoing Commitment and provided
further that the Company and the Agent may continue to deal
solely and directly with such Bank in connection with the
interest so assigned to an Assignee until (i) written notice of
such assignment, together with payment instructions, addresses
and related information with respect to the Assignee, shall have
been given to the Company and the Agent by such Bank and the
Assignee; (ii) such Bank and its Assignee shall have delivered to
the Company and the Agent an Assignment and Acceptance in the
form of Exhibit E ("Assignment and Acceptance") together with any
Note or Notes subject to such assignment and (iii) the assignor
Bank or Assignee has paid to the Agent a processing fee in the
amount of $3,500.

                  (b)      From and after the date that the Agent notifies
the assignor Bank that it has received (and provided its consent
with respect to) an executed Assignment and Acceptance and
payment of the above-referenced processing fee, (i) the Assignee
thereunder shall be a party hereto and, to the extent that rights
and obligations hereunder have been assigned to it pursuant to
such Assignment and Acceptance, shall have the rights and
obligations of a Bank under the Loan Documents, and (ii) the
assignor Bank shall, to the extent that rights and obligations
hereunder and under the other Loan Documents have been assigned
by it pursuant to such Assignment and Acceptance, relinquish its
rights and be released from its obligations under the Loan
Documents.


 
                                                        102

                 (c)      Within five Business Days after its receipt of
notice by the Agent that it has received an executed Assignment
and Acceptance and payment of the processing fee, (and provided
that it consents to such assignment in accordance with subsection
11.08(a)), the Company shall execute and deliver to the Agent,
new Notes evidencing such Assignee's assigned Loans and
Commitment and, if the assignor Bank has retained a portion of
its Loans and its Commitment, replacement Notes in the principal
amount of the Loans retained by the assignor Bank (such Nots to
be in exchange for, but not in payment of, the Notes held by such
Bank).  Immediately upon each Assignee's making its processing
fee payment under the Assignment and Acceptance, this Agreement
shall be deemed to be amended to the extent, but only to the
extent, necessary to reflect the addition of the Assignee and the
resulting adjustment of the Commitments arising therefrom. The
Commitment allocated to each Assignee shall reduce such
Commitments of the assigning Bank pro tanto.

                  (d)      Any Bank may at any time sell to one or more
commercial banks or other Persons not Affiliates of the Company
(a "Participant") participating interests in any Loans, the
Commitment of that Bank and the other interests of that Bank (the
"originating Bank") hereunder and under the other Loan Documents;
provided, however, that (i) the originating Bank's obligations
under this Agreement shall remain unchanged, (ii) the originating
Bank shall remain solely responsible for the performance of such
obligations, (iii) the Company, the Issuing Bank and the Agent
shall continue to deal solely and directly with the originating
Bank in connection with the originating Bank's rights and
obligations under this Agreement and the other Loan Documents,
and (iv) no Bank shall transfer or grant any participating
interest under which the Participant has rights to approve any
amendment to, or any consent or waiver with respect to, this
Agreement or any other Loan Document, except to the extent such
amendment, consent or waiver would require unanimous consent of
the Banks as described in the first proviso to Section 11.01. In
the case of any such participation, the Participant shall be
entitled to the benefit of Sections 4.01, 4.03 and 11.05 as
though it were also a Bank hereunder, and if amounts outstanding
under this Agreement are due and unpaid, or shall have been
declared or shall have become due and payable upon the occurrence
of an Event of Default, each Participant shall be deemed to have
the right of set-off in respect of its participating interest in
amounts owing under this Agreement to the same extent as if the
amount of its participating interest were owing directly to it as
a Bank under this Agreement.


 
                                                        103


                  (e)      Notwithstanding any other provision in this
Agreement, any Bank may at any time create a security interest
in, or pledge, all or any portion of its rights under and
interest in this Agreement and the Note held by it in favor of
any Federal Reserve Bank in accordance with Regulation A of the
FRB or U.S. Treasury Regulation 31 CFR Section 203.14, and such Federal
Reserve Bank may enforce such pledge or security interest in any
manner permitted under applicable law.

         11.09  Set-off.  In addition to any rights and remedies of
the Banks provided by law, if an Event of Default exists or the
Loans have been accelerated, each Bank is authorized at any time
and from time to time, without prior notice to the Company, any
such notice being waived by the Company to the fullest extent
permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any
time held by, and other indebtedness at any time owing by, such
Bank to or for the credit or the account of the Company against
any and all Obligations owing to such Bank, now or hereafter
existing, irrespective of whether or not the Agent or such Bank
shall have made demand under this Agreement or any Loan Document
and although such Obligations may be contingent or unmatured.
Each Bank agrees promptly to notify the Company and the Agent
after any such set-off and application made by such Bank;
provided, however, that the failure to give such notice shall not
affect the validity of such set-off and application.

         11.10  Automatic Debits of Fees.  With respect to any
commitment fee, arrangement fee, letter of credit fee or other
fee, or any other cost or expense (including Attorney Costs) due
and payable to the Agent, the Issuing Bank, the Arranger or the
Banks under the Loan Documents, the Company hereby irrevocably
authorizes BofA to debit any deposit account of the Company with
BofA in an amount such that the aggregate amount debited from all
such deposit accounts does not exceed such fee or other cost or
expense. If there are insufficient funds in such deposit accounts
to cover the amount of the fee or other cost or expense then due,
such debits will be reversed (in whole or in part, in BofA's sole
discretion) and such amount not debited shall be deemed to be
unpaid.  No such debit under this Section shall be deemed a set-
off.

         11.11  Notification of Addresses, Lending Offices, Etc.
Each Bank shall notify the Agent in writing of any changes in the
address to which notices to the Bank should be directed, of
addresses of any Lending Office, of payment instructions in
respect of all payments to be made to it hereunder and of such

 
                                                        104

other administrative information as the Agent shall reasonably
request.

         11.12  Counterparts.  This Agreement may be executed in any
number of separate counterparts, each of which, when so executed,
shall be deemed an original, and all of said counterparts taken
together shall be deemed to constitute but one and the same
instrument.

         11.13  Severability.  Wherever possible each provision of
this Agreement, the Pledge Agreements or any other instrument
agreement required hereunder shall be interpreted in such manner
as to be effective and valid under applicable law, but if any
provision of this Agreement, the Pledge Agreements or any other
instrument or agreement required hereunder shall be prohibited by
or invalid under such law, such provision shall be ineffective to
the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining
provisions of such agreement or instrument.

         11.14  No Third Parties Benefited.  This Agreement is made
and entered into for the sole protection and legal benefit of the
Company, the Banks, the Agent and the Agent-Related Persons, and
their permitted successors and assigns, and no other Person shall
be a direct or indirect legal beneficiary of, or have any direct
or indirect cause of action or claim in connection with, this
Agreement or any of the other Loan Documents.

         11.15  Governing Law and Jurisdiction.

                  (a)      THIS AGREEMENT, THE PLEDGE AGREEMENTS AND THE
NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAW OF THE STATE OF CALIFORNIA EXCEPT TO THE EXTENT THAT THE
VALIDITY OR PERFECTION OF ANY SECURITY INTERESTS OR REMEDIES
UNDER ANY LOAN DOCUMENTS ARE GOVERNED BY THE LAWS OF A STATE
OTHER THAN CALIFORNIA; PROVIDED THAT THE AGENT AND THE BANKS
SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

                  (b)      ANY LEGAL ACTION, PROCEEDING OR LITIGATION BASED
HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS
AGREEMENT, THE PLEDGE AGREEMENTS OR ANY OTHER LOAN DOCUMENT, OR
ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER
ORAL OR WRITTEN) OR ACTIONS OF THE AGENT, THE BANKS OR THE
COMPANY MAY BE BROUGHT AND MAINTAINED IN THE COURTS OF THE STATE
OF CALIFORNIA OR IN THE UNITED STATES DISTRICT COURT FOR THE
CENTRAL DISTRICT OF CALIFORNIA; PROVIDED, HOWEVER, THAT ANY SUIT
SEEKING ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY
BE BROUGHT, AT THE AGENT'S OPTION, IN THE COURTS OF ANY

 
                                                        105


JURISDICTION WHERE SUCH COLLATERAL OR OTHER PROPERTY MAY BE
FOUND.  BY THE EXECUTION AND DELIVERY OF THIS AGREEMENT OR THE
PLEDGE AGREEMENTS, EACH OF THE COMPANY, THE BANKS AND THE AGENT
HEREBY CONSENTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY AND
EXPRESSLY AND IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE
JURISDICTION OF THE COURTS OF THE STATE OF CALIFORNIA AND OF THE
UNITED STATES DISTRICT COURT FOR THE CENTRAL DISTRICT OF
CALIFORNIA FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH
ABOVE AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT RENDERED

AND THE COMPANY FURTHER IRREVOCABLY CONSENT TO THE SERVICE OF
PROCESS BY ANY MEANS PERMITTED BY CALIFORNIA LAW INCLUDING BY
REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL SERVICE WITHIN
OR WITHOUT THE STATE OF CALIFORNIA.  THE AGENT, THE BANKS AND THE
COMPANY HEREBY EXPRESSLY AND IRREVOCABLY WAIVE, TO THE FULLEST
EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH THEY MAY HAVE OR
HEREAFTER MAY HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION
BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT
ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.
TO THE EXTENT THAT THE AGENT, THE BANKS AND THE COMPANY HAVE OR
HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY COURT
OR FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE,
ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR
OTHERWISE) WITH RESPECT TO THEM OR THEIR PROPERTY, THE AGENT, THE
BANKS AND THE COMPANY HEREBY IRREVOCABLY WAIVE SUCH IMMUNITY IN
RESPECT OF THEIR OBLIGATIONS UNDER THIS AGREEMENT, THE PLEDGE
AGREEMENTS AND THE OTHER LOAN DOCUMENTS.

         11.16  Waiver of Jury Trial.  THE COMPANY, THE BANKS AND THE
AGENT EACH WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY OF
ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF OR
RELATED TO THIS AGREEMENT, THE PLEDGE AGREEMENTS, THE OTHER LOAN
DOCUMENTS, ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS
(WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE COMPANY, THE PLEDGOR
SUBSIDIARIES, THE BANKS OR THE AGENT, OR THE TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY, IN ANY ACTION, PROCEEDING OR
OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE PARTIES
AGAINST ANY OTHER PARTY OR ANY AGENT-RELATED PERSON, PARTICIPANT
OR ASSIGNEE, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT
CLAIMS, OR OTHERWISE.  THE COMPANY, THE BANKS AND THE AGENT EACH
AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A
COURT TRIAL WITHOUT A JURY.  WITHOUT LIMITING THE FOREGOING, THE
PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY
JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION,
COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN
PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS
AGREEMENT, THE PLEDGE AGREEMENTS, OR THE OTHER LOAN DOCUMENTS OR
ANY PROVISION HEREOF OR THEREOF.  THIS WAIVER SHALL APPLY TO ANY

 
                                                        106

SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO
THIS AGREEMENT, THE PLEDGE AGREEMENTS, AND THE OTHER LOAN
DOCUMENTS.  THE COMPANY ACKNOWLEDGES AND AGREES THAT IT HAS
RECEIVED FULL AND SUFFICIENT CONSIDERATION FOR THIS PROVISION
(AND EACH OTHER PROVISION OF EACH OTHER LOAN DOCUMENT TO WHICH IT
IS A PARTY) AND THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR
THE AGENT AND THE BANKS ENTERING INTO THIS AGREEMENT AND EACH
SUCH OTHER LOAN DOCUMENT.

         11.17  Entire Agreement.  This Agreement, together with the
Pledge Agreements and the other Loan Documents, embodies the
entire agreement and understanding among the Company, the Pledgor
Subsidiaries, the Banks and the Agent, and supersedes all prior
or contemporaneous agreements and understandings of such Persons,
verbal or written, relating to the subject matter hereof and

                                SCHEDULE 6.03

                              REQUIRED APPROVALS


1.  The Company or certain of its Subsidiaries will be required, following the 
Closing, to notify applicable insurance regulators of the transaction
evidenced by the Loan Documents by filing amendments to their Insurance
Holding Company System Registration Statement or equivalent statement.

2.  Prior to obtaining ownership and/or control, or transferring ownership 
and/or control of the Pledged Shares of Subsidiaries subject to regulation
by state insurance regulatory authorities, the Agent and the Banks may need
to make certain filings with those authorities and obtain requisite
regulatory approval.  Under apllicable anti-affiliation statutes, banks and
certain other financial institutions may be prohibited from owning or 
controlling any subsidiary subject to state insurance legislation.

3.  Section 18442 of the California Financial Code states that "(a)n industrial 
loan company shall not make any loan of money or property to or guarantee the
obligation of any person upon the security of its capital (including the
shares of capital stock) of the company, its holding company, or its
affiliates."  Although Section 18442 may be read to prohibit the pledge of
shares of a corporation which owns an industrial loan company (such as in the 
case of CIIF and CII Premium Finance Company), a representative of the
Industrial Loan Department of the Department of Corporations has taken the
position in a telephonic conversation that Section 18442 is not intended to
prohibit the pledge of shares of the parent company.

filed a Second Amended Complaint that also alleges negligent misrepresentation.

                  (c)  There  shall  be  added to  Section  11.01 of the  Credit
Agreement a new Clause (f) reading in its entirety as follows:

     "(f) release any portion of the Pledged Collateral;"

                  2.22     Amendment of Schedules.

                  (a) Schedule  2.01 of the Credit  Agreement is hereby  amended
and restated to read in its entirety as set forth on Schedule 2.01 hereto.

                  (b) Schedule 5.01(g) of the Credit Agreement is hereby amended
and restated to read in its entirety as set forth on Schedule 5.01(g) hereto.

                  (c) Schedule  11.02 of the Credit  Agreement is hereby amended
and restated to read in its entirety as set forth on Schedule 11.02 hereto.

                  2.23     Addition of New Banks.

                  (a) Upon the  effectiveness of this First  Amendment,  each of
the New Banks shall (i) be a party to the Credit  Agreement;  (ii) assume all of
the  rights  and  obligations  of a  Bank  under  the  Credit  Agreement  with a
Commitment  in the amount set forth  opposite  such Bank's name in Schedule 2.01
attached hereto; and (iii) be secured by the Collateral.  The Commitments of the
New Banks and the revised Commitments of the existing Banks will be effective as
of November 25, 1998 (the "New Commitment  Effective  Date").  As of the date of
this First Amendment, there are three outstanding Borrowings of LIBOR Rate Loans
(the  "Outstanding  Loans").  It is the intention of the parties that on the New
Commitment  Effective Date the New Banks shall  purchase  assignments in each of
the Outstanding Loans in an amount equal to each such Bank's respective Pro Rata
Share.  The interest rate payable by the Company on the Outstanding  Loans shall
remain unchanged;  however,  the interest rate distributable to the New Banks on
their  portion of the New Loans shall be equal to the LIBOR Rate for an Interest
Period of three months,  determined as of November 23, 1998, plus the Applicable
Margin for LIBOR Rate Loans. On the New Commitment Effective Date, each New Bank
shall pay to the Agent (for delivery to BofA and First Union) its Pro Rata Share
of the aggregate  principal  amount of the Outstanding  Loans. The obligation of
each New Bank to so provide  its  purchase  price to the Agent shall be absolute
and  unconditional  and shall not be affected by the  occurrence of a Default or
Event of  Default.  Each New Bank that has  provided  to the Agent the  purchase
price due for its  assignment in such Loans shall  thereupon  acquire a pro rata
participation,  to the  extent of such  payment,  in the claim of BofA and First
Union against the Company for principal and shall share,  in accordance with its
Pro Rata Share,  in any  principal  payment  made by the Company with respect to
such claim.

                  (b) From and after the New Commitment  Effective Date, the New
Banks  shall be  entitled  to  their  Pro Rata  Share of all  interest  and fees
thereafter accruing under this

Credit  Agreement  (including,  without  limitation,  interest  on each such New
Bank's Pro Rata Share of the  Outstanding  Loans).  All Loans made after the New
Commitment  Effective  Date shall be made by the Banks  pursuant to the Pro Rata
Shares set forth in Schedule 2.01 attached hereto.

                  (c) Each of the New Banks hereby (i)  warrants and  represents
that it is authorized to become a party to the Credit  Agreement;  (ii) appoints
and authorizes the Agent to take such action,  exercise such powers, and perform
such duties  under the Credit  Agreement  as are  specifically  delegated  to or
required of the Agent by the terms of the Credit  Agreement,  together with such
other powers as are reasonably incidental thereto; and (iii) agrees that it will
abide and be bound by all of the terms,  covenants and  agreements,  and perform
all of the obligations,  which by the terms of the Credit Agreement are required
to be abided and  performed  by it as a Bank and shall be entitled to all of the
rights,  benefits and  privileges  available or accruing to Banks under the Loan
Documents.

         3. Representations and Warranties.  The Company represents and warrants
to the Agent and the Banks that, on and as of the date hereof,  and after giving

contractual  restriction  or  violate  or  contravene  any  law or  governmental
regulation  or court decree or order  binding on or affecting  the Company which
individually or in the aggregate does or could  reasonably be expected to have a
Material Adverse Effect; or (c) result in, or require the creation or imposition
of, any Lien on any of the Company's properties. No approval or authorization of
any  governmental  authority  is required to permit the  execution,  delivery or
performance  by the  Company  of  this  First  Amendment,  or  the  transactions

                  3.4  Incorporation  of Certain  Representations.  After giving

Amendment  dated as of  November 23,  1998 (as further  amended or modified from

                                                     RECITALS

     WHEREAS, the Company has requested the Agent and the Banks to amend certain
provisions of the Credit  Agreement,  and the Agent and the Banks are willing to
do so, on the terms and conditions specified herein;

     WHEREAS, the New Bank wishes to be added to the Credit Agreement as a Bank,
and the Company,  the Agent and the existing Banks are willing to permit the New
Bank to be so added;

     NOW,  THEREFORE,  for good and  valuable  consideration,  the  receipt  and
adequacy of which are hereby acknowledged, the parties hereby agree as follows:

     1.  Terms.  All terms used  herein  shall have the same  meanings as in the
Credit Agreement unless otherwise defined herein.

         2.       Amendment.  The Credit Agreement is hereby amended as follows:

                  2.1      Amendment to Section 8.10.

     (a) Section 8.10 of the Credit  Agreement  is hereby  amended by adding the
following clause immediately after the phrase  "notwithstanding  the foregoing,"
in the seventh line from the end of such Section:

     "(i) any  Wholly-Owned  Subsidiaries  may declare and pay  dividends to the
Company and (ii) "

                  2.2      Amendment to Section 8.14.

     (a) Clause (ii) of subsection  (b) of Section 8.14 of the Credit  Agreement
is hereby  amended by  replacing  the phrase "for the period  commencing  on the
Closing Date and

                                                         1

     ending on the date of determination"  and with the following  phrase:  "for

                  2.3      Amendment to Section 8.17.

     (a) The  proviso at the end of  Section  8.17 of the  Credit  Agreement  is
hereby  amended by inserting the  following  clause  immediately  after the word
"foregoing":  "the Company may consummate any of the  transactions  set forth on
Schedule 8.17 and".

                  2.4      Amendment to Section 9.02.

     (a) The following  sentence shall be added to the end of the first sentence
of Section 9.02:  "Upon any  acceleration of the Loans pursuant to the foregoing
provisions,  the Company  shall  deposit  with the Agent cash  collateral  in an
amount  equal to the  aggregate  undrawn  amount of all  Letters of Credit  then
outstanding (the "Maximum Available Amount");  provided that in the event of any
drawing  under any Letter of Credit  thereafter,  the Agent  shall use such cash
collateral to reimburse such drawing and provided  further that, in the event of
any  cancellation  or expiration of any Letter of Credit,  the Agent shall apply
the difference  between the Maximum  Available Amount  immediately prior to such
cancellation or expiration and the Maximum  Available Amount  immediately  after
such cancellation or reduction, first, to the payment in full of any outstanding
Obligations,  and  second,  to the  Company or to such  other  Person who may be
lawfully entitled to receive such funds or as a court of competent  jurisdiction
may direct."

     2.5 Amendment to Section  10.10.  Section 10.10 of the Credit  Agreement is
hereby amended and restated in its entirety to read as follows:

                  10.10    Withholding Tax.

     (a) If any Bank is a "foreign corporation, partnership or trust" within the
meaning of the Code and such Bank claims exemption from, or a reduction of, U.S.
withholding  tax under Sections 1441 or 1442 of the Code,  such Bank agrees with
and in favor of the Agent and the Company, to deliver to the Agent:

     (i)  if such Bank claims an exemption from, or a reduction of,  withholding
tax under a United States tax treaty, two properly completed and executed copies
of IRS Form 1001 before the payment of any interest in the first  calendar  year
and before the payment of any interest in each third  succeeding  calendar  year
during which interest may be paid under this Agreement;

     (ii)  if such Bank claims that interest paid under this Agreement is exempt
from United States  withholding  tax because it is effectively  connected with a
United  States  trade or  business  of such Bank,  two  properly  completed  and
executed  copies of IRS Form 4224 before the  payment of any  interest is due in
the first taxable year of

                                                         2

     such Bank and in each  succeeding  taxable  year of such Bank during  which
interest may be paid under this Agreement; and

     (iii)  to the extent it is legally  able to do so, such other form or forms
as may be  required  under  the Code or other  laws of the  United  States  as a
condition to exemption from, or reduction of, United States withholding tax.

     Such Bank agrees to promptly notify the Agent and the Company of any change
in circumstances  which would modify or render invalid any claimed  exemption or
reduction.

     (b) If any Bank claims  exemption  from, or reduction of,  withholding  tax
under a United States tax treaty by providing IRS Form 1001 and such Bank sells,
assigns,  grants a participation  in, or otherwise  transfers all or part of the
Obligations of the Company to such Bank, such Bank agrees to notify the Agent of
the  percentage  amount  in  which  it is no  longer  the  beneficial  owner  of
Obligations  of the  Company  to such  Bank.  To the  extent of such  percentage
amount, the Agent will treat such Bank's IRS Form 1001 as no longer valid.

     (c) If any Bank claiming  exemption from United States  withholding  tax by
filing IRS Form 4224 with the Agent grants a participation in all or part of the
Obligations  of the Company to such  originating  Bank,  such  originating  Bank
agrees to undertake sole  responsibility  for complying with the withholding tax
requirements  imposed by Sections  1441 and 1442 of the Code with respect to its
participant.

     (d) If any Bank is entitled to a reduction  in the  applicable  withholding
tax,  the Agent may withhold  from any  interest  payment to such Bank an amount
equivalent  to the  applicable  withholding  tax after  taking into account such
reduction.  However, if the forms or other documentation  required by subsection
(a) of this Section are not delivered to the Agent,  then the Agent may withhold
from any  interest  payment  to such  Bank  not  providing  such  forms or other
documentation an amount equivalent to the applicable  withholding tax imposed by
Sections 1441 and 1442 of the Code, without reduction.

     (e) If the IRS or any other Governmental  Authority of the United States or
other  jurisdiction  asserts  a claim  that  the  Agent or the  Company  did not
properly  withhold  tax  from  amounts  paid to or for the  account  of any Bank
(because such Bank failed to notify the Agent of a change in circumstances which
rendered the exemption from, or reduction of,  withholding tax ineffective) such
Bank shall  indemnify  the Agent and the  Company  fully for all  amounts  paid,
directly  or  indirectly,  by the  Agent  or the  Company  as tax or  otherwise,
including  penalties  and  interest,  and  including  any taxes  imposed  by any
jurisdiction  on the amounts  payable to the Agent under this Section,  together
with all costs and expenses  (including  Attorney Costs).  The obligation of the
Banks under this subsection shall survive the payment of all Obligations and the
resignation or replacement of the Agent.


                                                         3

                  2.6      Amendment of Schedules.

     (a) Schedule 2.01 of the Credit Agreement is hereby amended and restated to
read in its entirety as set forth on Schedule 2.01 hereto.

     (b) Schedule  11.02 of the Credit  Agreement is hereby amended and restated
to read in its entirety as set forth on Schedule 11.02 hereto.

                  2.7      Addition of New Bank.

     (a) Upon the date of effectiveness of this Second Amendment (the "Effective
Date"),  the New Bank shall (i) be a party to the Credit Agreement;  (ii) assume
all of the rights and  obligations  of a Bank under the Credit  Agreement with a
Commitment  in the amount set forth  opposite  such Bank's name in Schedule 2.01
attached hereto; and (iii) be secured by the Collateral.  On the Effective Date,
the New Bank shall purchase and assume, and BofA and First Union shall each sell
to the New Bank, 25% of its Commitment under the Credit Agreement, including 25%
of each of the  outstanding  Loans of BofA and First Union (with such  purchase,
assumption  and sale being  deemed to have been  completed  upon  payment of the
purchase price in the manner  referred to below).  As of the date of this Second
Amendment,  there are four outstanding Borrowings of LIBOR Rate Loans, the terms
of which are more particularly  described on Exhibit A hereto. The interest rate
payable by the Company on its outstanding Loans shall not change;  however,  the
interest  rate  distributable  to the  New  Bank  on its  portion  of the  Loans
purchased  from BofA and  First  Union  shall be equal to the LIBOR  Rate for an
Interest  Period of one or three months (as described on Exhibit A),  determined
as of January 15,  1999, plus the Applicable Margin for LIBOR Rate Loans. On the
Effective  Date,  the New Bank shall  assume the  Commitment  of, and pay to the
Agent (for  delivery to BofA and First Union) the  purchase  price for the Loans
sold by, BofA and First Union.  The obligation of the New Bank to so provide its
purchase price to the Agent shall be absolute and unconditional and shall not be
affected by the  occurrence of a Default or Event of Default.  Upon the delivery
by the New Bank to the Agent of the purchase  price due for such Loans,  the New
Bank shall thereupon hold an assignment,  to the extent of such payment,  in the
claim of BofA and First Union against the Company for principal and shall share,
in  accordance  with its Pro Rata Share,  in any  principal  payment made by the
Company with respect to such claim.

     (b) From and after the New Commitment Effective Date, the New Bank shall be
entitled  to its Pro Rata Share of all  interest  and fees  thereafter  accruing
under this Credit Agreement (including, without limitation,  interest on the New
Bank's Pro Rata Share of the  Outstanding  Loans).  All Loans made after the New
Commitment  Effective  Date shall be made by the Banks  pursuant to the Pro Rata
Shares set forth in Schedule 2.01 attached hereto.

     (c) The New Bank hereby (i) warrants and  represents  that it is authorized
to become a party to the Credit  Agreement;  (ii)  appoints and  authorizes  the
Agent to take such

                                                         4

     action,  exercise  such  powers,  and perform  such duties under the Credit
Agreement as are specifically delegated to or required of the Agent by the terms
of the  Credit  Agreement,  together  with such other  powers as are  reasonably
incidental  thereto;  and (iii) agrees that it will abide and be bound by all of
the terms, covenants and agreements,  and perform all of the obligations,  which
by the terms of the Credit  Agreement are required to be abided and performed by
it as a Bank and shall be entitled to all of the rights, benefits and privileges
available or accruing to Banks under the Loan Documents.

     3.  Representations and Warranties.  The Company represents and warrants to

generally or by equitable principles relating to enforceability.

     3.3 No Legal Obstacle to Amendment. The execution, delivery and performance

restriction or violate or contravene any law or governmental regulation or court
decree or order binding on or affecting the Company which individually or in the
aggregate  does or could  reasonably  be  expected  to have a  Material  Adverse

performance  by the  Company  of  this  Second  Amendment,  or the  transactions
contemplated hereby.

     3.4  Incorporation of Certain  Representations.  After giving effect to the
terms of this  Second  Amendment,  the  representations  and  warranties  of the
Company set forth in Article VI of the Credit  Agreement are true and correct in

nor shall anything herein contained be deemed to prevent Employee from investing

Employee shall complete a Conflict of Interest form by February 15 of each



                                                       4

     calendar  year and submit it to  Employer  for  review.  All  conflicts  of
interest or any potential conflicts of interest which arise during the year must
be immediately  reported to Employer.  All conflict of interest concerns must be
resolved  to  the  reasonable   satisfaction  of  Employer  as  a  condition  of

subsidiaries, including without limiting the generality of the foregoing, any of
their customers, the prices they obtain from providers or have obtained from the
sale of,  or at  which  they  sell or have  sold,  its  services,  or any  other
information  concerning  the  business of Employer  or its  subsidiaries,  their
manner of operation,  or their plans, if such a disclosure  would be detrimental
to the business  interests  of Employer or its  subsidiaries.  2. If  Employee's
employment  hereunder is terminated by either party at any time hereafter,  then
Employee agrees to turn over to Employer all papers, documents,  working papers,
correspondence,  memos and any and all other documents in Employee's  possession

                                   ARTICLE VI

                            NONCOMPETITION AGREEMENT

     1. Employee acknowledges that in Employee's employment hereunder,  Employee
will have  continual  contacts with the groups,  members,  and providers who are
covered by or  associated  with the  managed  health  care  programs  offered by
Employer or its  subsidiaries  in Nevada and other states.  In all of Employee's
activities, Employee, through the nature of Employee's work, will have access to
and will acquire confidential information related to the business and operations
of Employer and its subsidiaries,  including, without limiting the generality of
the foregoing,  member and group lists, and confidential information relating to
processes,  plans,  methods of doing  business  and  special  needs of  doctors,
hospitals,  members,  groups,  pharmacies,  or other health care  providers  who
contract with Employer or its subsidiaries.  Employee acknowledges that all such
information  is  the  property  of  Employer  or  its  subsidiaries  solely  and
constitutes  confidential  information  of such  parties;  that  the  disclosure
thereof  would  cause  substantial  loss to the  goodwill  of  Employer  and its
subsidiaries;  that disclosure thereof to Employee is being made only because of
the position of trust and  confidence  which Employee will occupy and because of
Employee's agreement to the restrictions herein contained; that his knowledge of
these matters would enable him, on  termination  of this  Agreement,  to compete
with Employer or its  subsidiaries  in a manner likely to cause Employer and its
subsidiaries  irreparable harm, and disclosure of such matters would,  likewise,
cause such



                                                       6

     harm;  and that the  restrictions  imposed upon  Employee  herein would not
prohibit Employee in earning a living.

     2. It is understood and agreed by Employee and Employer that the essence of
this  Employment  Agreement is the mutual  covenants of the parties herein made,
that the present and future  members and groups of Employer or its  subsidiaries
will remain Employer's or its  subsidiaries'  members and groups during the term
of this Agreement and following its termination for any reason. In consideration
for the  employment and continued  employment of Employee by Employer,  and also
for the amount received by Employee as compensation, Employee hereby irrevocably
warrants, covenants, and agrees as follows:

     (a)  during  the  term of  Employee's  employment  and  after  leaving  the
employment  of  Employer  for any  reason,  whether  involuntary  or  voluntary,
Employee  will not take any action  whatsoever  which may or might  disturb  any
existing business relationship of Employer or its subsidiaries with any doctors,
groups, members, hospitals,  pharmacies or other health care providers in Nevada
who contract with Employer or its subsidiaries;

     (b) for a period of one (1) year after leaving the  employment of Employer,
Employee will not solicit business from the members or groups of Employer or its
subsidiaries  in Nevada,  or in any manner  disrupt  any  business  relationship
Employer or its  subsidiaries  has with any  contracted  health care provider in
Nevada with whom Employee came in contact as an employee of Employer.



                                                       7

     (c) for a period of one (1) year after leaving the  employment of Employer,
Employee will not, either directly or indirectly, work for any present or future
competitors of Employer operating in the state of Nevada who in any manner offer
any managed health care programs,  insurance coverage, or administer health care
claims for employers.  Such competitors  shall include,  but are not limited to,
HMOs, PPOs,  insurance companies,  utilization  management  companies,  or third
party administrators.

     3. The one (1) year period  specified in this Article will be tolled during
any period of breach of any of the terms of Article VI by Employee.

     4.  Employee  agrees  that in the  event  of a  breach  of any term of this
Agreement,  and more particularly,  in the event of a breach of any of the terms
and  provisions of Article VI,  Employer shall be entitled to secure an order in
any suit brought for that purpose to enjoin  Employee from  violating any of the
provisions of the  Agreement  and that,  pending the hearing and the decision on
the  application  for such  order,  Employer  shall be  entitled  to a temporary
restraining  order without  prejudice to any other remedy available to Employer,
all at the expense of Employee should Employer prevail in such action.  Employee
understands  that  the  covenants  of  this  Article  are  the  essence  of this
Employment  Agreement,  and without which no Employment  Agreement with Employee
would be entered into by Employer.

     5. The  provisions  of Article VI shall in no event be  construed  to be an
exclusive  remedy and such remedy shall be held and  construed to be  cumulative
and not



                                                       8



<PAGE>



     exclusive  of any rights or remedies,  whether in law or equity,  otherwise
available  under the  terms of this  Agreement  or under the laws of the  United
States or the state of Nevada.

     6. The covenants and  agreements  made by Employee in this Article VI shall
be construed as an agreement independent of any other provision in the Agreement
and the existence of any claim or cause of action by Employee against  Employer,
whether  predicated  on this  Agreement  or  otherwise,  shall not  constitute a
defense to the enforcement by Employer,  by injunctive  relief or otherwise,  of
the  provisions of Article VI. The  invalidity of all or any part of any section
or paragraph of this Article VI shall not render  invalid the  remainder of this
Article or any section hereof.

     7. No failure or failures on the part of Employer to enforce any  violation
by Employee  of this  Noncompetition  agreement,  shall  constitute  a waiver of
Employer's rights thereafter to enforce all of the terms, covenants,  provisions
and agreements herein contained.

                                   ARTICLE VII

                            TERMINATION OF EMPLOYMENT

established Sierra Health Services Policies and Procedures including appropriate

written notice. If Employee shall voluntarily  terminate employment all eligible

     compensation  and  benefits  as  are  routinely  made  available  to  other
employees of Employer at the same  organizational  level,  shall be paid or made
available to Employee.

     3. If Employer shall  terminate  Employee's  employment  hereunder  without
cause,  except as otherwise  set forth in  Paragraphs  6 and 7 of this  Article,
Employee  shall be entitled to nine (9) months  salary and all other  separation
compensation  and benefits as are routinely made available to other employees of
Employer at the same organizational level.

     4. In the event Employee's  employment  hereunder terminates for any reason
other than for cause, as set forth in Paragraph 6 of this Article,  Employee and
his/her family shall be eligible to remain covered under Employer's  health care
coverage program, at no expense, for a period of time equal to Employee's length
of  service  or until  Medicare  eligible,  whichever  occurs  first,  following
termination of such employment.

     5.  Notwithstanding  any other provision in this Agreement to the contrary,
Employee hereby agrees that any separation  compensation due to Employee,  other
than accrued  vacation,  shall be paid out 25% after the first 90 days,  37 1/2%
after  the first 180  days,  and the  remaining  37 1/2% at the end of 365 days,
except in the event of a change in control.  Payment of such amounts shall fully
release  Employer  from  any and all  liability  of  Employer  relating  to this
Agreement or the employment hereunder.  Any payments or such amounts which would
otherwise  be  payable  after a change in  control,  or arising as a result of a
change in control, shall be made in a lump sum within five (5)



                                                       10

business days  following the date of the change in control and shall,  except as
otherwise  provided in any other  benefit  program or in this  Agreement,  fully
release  Employer  from  any and all  liability  of  Employer  relating  to this
Agreement or the employment hereunder.

     6. If Employer  shall  terminate  Employee's  employment  due to Employee's
conduct  that is  materially  detrimental  to  Employer's  reputation,  business
relationships,  or for  misappropriation of Employer's funds,  Employee shall be
eligible for four (4) weeks  salary and any other  separation  compensation  and
benefits as are routinely made  available to other  employees of Employer at the
same  organizational  level,  as full and final  payment  under this  Agreement.
Payment of such amounts shall fully release  Employer from any and all liability
of Employer relating to this Agreement or the employment hereunder.

     7. (a) If Employee is unable to perform  Employee's  duties  hereunder,  by
reason of illness or incapacity  of any kind,  for a period of more than six (6)
months in excess of accrued sick leave,  Employee's  employment hereunder may be
terminated by Employer at its absolute discretion with one week of prior written
notice.

     (b) If  Employee's  illness or  incapacity  shall have ended,  and Employee
shall have assumed  Employee's duties hereunder,  prior to the date specified in
the notice of  termination,  Employee  shall be  entitled  to resume  Employee's
employment hereunder as if such notice had not been given.

     8. In the event of a change in control of  Employer,  whereby any  "person"
(as  such  term is used in  Sections  3(a)(9)  and  13(d)(3)  of the  Securities
Exchange Act of 1934)



                                                       11

     is or becomes the beneficial owner,  directly or indirectly,  of securities
of Employer  representing  51% or more of the combined  voting power of the then
outstanding  securities of Employer, and such change in control was not approved
by a majority of the Board of Directors of Employer,  Employee,  at his/her sole
option,  shall be entitled to terminate his/her  employment  hereunder and, upon
such  termination,  will be  entitled  to a cash  amount  equal to  (2.0)  times
Employee's  current  salary and the target  annual  bonus for which  Employee is
eligible  in the  year  of  termination,  together  with  any  other  separation
compensation  and benefits as are routinely made available to other employees of
Employer at the same organizational  level.  Employee's right to terminate under
this Paragraph 8 may be exercised at the time of the change in control or at any
time within two years after the change in control, including upon receipt of any
notice that  Employer has elected to  terminate  Employee's  employment  without
cause during such  two-year  period.  Payment of such amounts shall be made in a
lump sum within five (5) business days  following  the date such amounts  become
payable hereunder and shall,  except as otherwise  provided in any other benefit
program or in this Agreement,  fully release Employer from any and all liability
of Employer  relating to this Agreement or the employment  hereunder.  9. In the
event of a change in control of Employer,  whereby any "person" (as such term is
used in Sections 3(a)(9) and 13(d)(3) of the Securities Exchange Act of 1934) is
or becomes the  beneficial  owner,  directly or  indirectly,  of  securities  of
Employer  representing  51% or more of the  combined  voting  power  of the then
outstanding securities

     of  Employer,  and such  change in control is approved by a majority of the
Board of  Directors  of Employer,  Employee,  at his/her  sole option,  shall be
entitled to terminate his/her  employment  hereunder and, upon such termination,
will be entitled to a cash amount equal to (2.0) times Employee's current salary
and the  target  annual  bonus for which  Employee  is  eligible  in the year of
termination, together with any other separation compensation and benefits as are
routinely   made   available  to  other   employees  of  Employer  at  the  same
organizational  level,  if, within two (2) years after the effective date of the
change  in  control  any one of the  following  occurs:  (a) the  assignment  to
Employee of any duties  inconsistent with Employee's position (including status,
offices,   titles,   and  reporting   requirements),   authority,   duties,   or
responsibilities  or any other action by the Employer that results in a material
diminution in such position,  authority, duties, or responsibilities,  excluding
for this  purpose  an action  not taken in bad  faith  and that is  remedied  by
Employer  within 10 days  after  receipt of written  notice by  Employee;  (b) a
reduction in Employee's  annual base salary or target bonus;  (c) the relocation
of Employer's  principle executive offices to a location more than 75 miles from
the current location of such offices or (d), in the event such change in control
occurs  within  the final two years  prior to the  calendar  date  stated as the
termination  date of the  Agreement  in Article II, and if, prior to such stated
termination date and prior to termination of Employee's employment, Employer has
not offered to enter into an  extension  of this  employment  agreement or a new
employment agreement providing benefits substantially equal to those under this



                                                       13



<PAGE>



     agreement  for a term to extend  until at least two years after the date of
such change in control.  In  addition,  if  Employee's  employment  hereunder is
terminated  for reasons  other than those set forth in Paragraph 6 and 7 of this
Article  within two (2) years  after the  effective  date of a change in control
which was  approved by a majority of  Employer's  Board of  Directors,  Employee
shall be  entitled  to a cash amount  equal to (2.0)  times  Employee's  current
salary and the target annual bonus for which Employee is eligible in the year of
termination, together with all other separation compensation and benefits as are
routinely   made   available  to  other   employees  of  Employer  at  the  same
organizational level. Payment of such amounts shall be made in a lump sum within
five (5) business days following the date such amounts become payable hereunder,
and shall,  except as otherwise provided in any other benefit program or in this
Agreement,  fully  release  Employer  from  any and all  liability  of  Employer
relating to this Agreement or the employment hereunder.

     10. Anything contained herein to the contrary  notwithstanding in the event
that Employer shall discontinue  operation of Employer other than as a result of
a merger, consolidation or acquisition,  then this Agreement shall terminate and
the provisions of Article VI shall  terminate as of the last day of the month in
which Employer  ceases  operation with the same force and effect as if such last
day of the month were originally set as the termination date hereof.

11. Any amounts payable under this Article VII shall also be payable to Employee



                                                       14



<PAGE>



     in the event Employee is terminated  without cause during the 90-day period
prior to a Change in Control.

     12.  Whether  or  not  Employee  becomes  entitled  to any  payments  under
Paragraphs  1 through  11 of this  Article  VII,  if any  payments  or  benefits
received,  or to be received,  by Employee  (including the vesting of any option
and other non-cash benefits and property),  whether pursuant to any provision of
this Agreement or any other plan,  arrangement or agreement with Employer or any
affiliated  company,  excluding  the Gross- Up Payment  described  herein  (such
payments and benefits being the "Total Payments"), will be subject to any excise
tax imposed under section 4999 of the Internal  Revenue Code of 1986, as amended
(such excise tax,  including  penalties and interest thereon,  being the "Excise
Tax"),  Employer  shall pay to Employee  an  additional  amount  (the  "Gross-Up
Payment") such that the net amount retained by Employee, after reduction for any
Excise Tax on the Total  Payments and any federal and Excise Tax on the Gross-Up
Payment,  shall be  equal to the sum of (i) the  Total  Payments  plus  (ii) any
deductions  disallowed for federal income tax purposes  because of the inclusion
of the Gross-Up Payment in Executive's  adjusted gross income  multiplied by the
Executive's  highest  marginal rate of federal income  taxation for the calendar
year in which the Gross-Up Payment is to be made.

                                 AMENDMENT NO. 2

                    TO THE ASSET SALE AND PURCHASE AGREEMENT

     THIS AMENDMENT ("Amendment") is entered into as of October 31, 1998, by and
between Kaiser Foundation  Health Plan of Texas, a Texas non-profit  corporation
("Seller"),  and Texas  Health  Choice,  L.C.,  f/k/a HMO Texas,  L.C.,  a Texas
limited liability company ("Buyer").

                                                      RECITAL

     The  undersigned  parties have  entered  into that  certain  Asset Sale and
Purchase Agreement,  dated June 5, 1998, as amended on August 7, 1998 ("Purchase
Agreement"),  and the parties desire to further amend the Purchase  Agreement as
set forth herein.

     NOW,  THEREFORE,  for and in  consideration  of the above  recitals and the
representations,  warranties, mutual covenants, and agreements herein expressed,
and for other good and valuable  consideration,  the receipt and  sufficiency of
which are hereby expressly acknowledged, the parties hereby agree as follows:

     1.  Identity of Buyer.  The parties  hereby  agree to amend (i) the initial
paragraph of the Purchase Agreement,  (ii) Section 15.1 regarding notices, (iii)
the  signature  blocks  of  Buyer,  and (iv)  any  other  place in the  Purchase
Agreement which  references HMO Texas,  L.C. as Buyer, to change the identity of
the Buyer from HMO Texas,  L.C., a Texas  limited  liability  company,  to Texas
Health Choice, L.C., a Texas limited liability company.

     2.  Confidentiality  Agreements.  The parties hereby  acknowledge  that the
references to the Confidentiality  Agreements dated March 28, 1998 and March 30,
1998 in paragraph E of the Recitals in the Purchase Agreement are erroneous, and
hereby  agree  to  amend  such  paragraph  to  change  such  references  to  the
Confidentiality  Agreements  dated March 24, 1998 and March 27, 1998.  Copies of
the  Confidentiality  Agreements  dated  March 24,  1998 and March 27,  1998 are
attached as Exhibits A and B to this Amendment.

     3. Texas Group 3000 Issues.  The parties  hereby  acknowledge  that Section
1.4.4 of the  Purchase  Agreement  shall be  interpreted  to mean that the Texas
Group  3000  Members  shall not be  counted  in the  Membership  Base  under the
Earn-Out  Accounts for the purpose of calculating any additional  purchase price
paid by Buyer to Seller thereunder.  In addition,  other members employed by the
Group 3000 Members' employers (such employers to be determined as of the Closing
Date) shall not be counted unless (i) such member is listed on Schedule 1.4.4 as
a  National  Account or (ii)  Seller  brings  new  members  to areas  other than
Dallas/Fort  Worth in accordance  with the  provisions of Section  1.4.4.  As an
example  of  subsection  (i),  if XYZ Co.  is listed as a  National  Account  in
Schedule  1.4.4 and an  employee of XYZ Co. is listed as a Group 3000 Member but
is not included in the membership count in Schedule 1.4.4, the


     employee  shall  never  count  in  the  Membership  Base  for  purposes  of
calculating the Earn-Out Accounts;  however,  increases in the number of members
employed  by XYZ Co.  and who are not a Group 3000  Member at  Closing  shall be
counted  in the  Membership  Base  for  purposes  of  calculating  the  Earn-out
Accounts.

     4. Old National Accounts. In addition to updating Schedule 1.4.4 to make it
accurate  as of the  Closing,  the  parties  agree (i) to  delete  intentionally
Columbia  Healthcare  members from the  Membership  Base for purposes of Section
1.4.4,  notwithstanding that Columbia Healthcare is an Old National Account, and
(ii) to not count  Columbia  Healthcare  members in the New Accounts or Earn-Out
Accounts. This shall affect Section 1.4.4 of the Purchase Agreement only.

     5.  Closing.  The parties  hereby  agree that  Section 1.5 of the  Purchase
Agreement shall be amended to change the reference regarding the time of Closing
from 12:01:01 a.m. to 11:59:59 p.m. on the Closing Date.

     6. Columbia Hospital  Contract.  In order to simplify the process described
in Section 1.6.3(b) of the Purchase  Agreement relating to the Columbia Hospital
Contract,  the  parties  agree to delete  the text of  Section  1.6.3(b)  of the
Purchase Agreement in its entirety, and replace such text with the following:

     Buyer has arranged to amend and assume that certain contract between Seller
and Columbia  North Texas  Division,  Inc.  ("Columbia"),  dated January 1, 1995
("Columbia  Hospital  Contract")  pursuant to a letter dated September 17, 1998,
from Larry S. Howard to Thomas O. Corley, which sets forth the agreement between
Buyer and Columbia and the consent of Columbia to the  assignment and assumption
of the Columbia Hospital Contract.  The following chart sets forth the change in
Equivalent Per Diem rates resulting from the assignment of the Columbia Hospital
Contract to Buyer:
