Item 5.  Other Events

The following discussion contains certain cautionary statements regarding Sierra
Health  Services,  Inc.'s  business and results of  operations,  which should be
considered  by our  stockholders  or any  reader of our  business  or  financial
information. Unless otherwise indicated, the terms "our", "us" and "we" refer to
Sierra Health Services, Inc., and its subsidiaries. This information is provided
to enable us to avail  ourselves of the "safe harbor"  provisions of the Private
Securities  Litigation  Reform  Act of 1995.  The  following  factors  should be
considered in  conjunction  with any  discussion  of our  operations or results,
including any forward-looking statements, as well as comments contained in press
releases,  presentations  to  securities  analysts  or  investors  and all other
communications made by our representatives or us. Words or their variations used
to  identify  forward-looking  statements  include,  but are not limited to, the
following:  anticipates,  believes,  expects,  estimates, hopes, intends, plans,
projects and seeks.

In making these  statements,  we disclaim any intention or obligation to address
or update each factor in future filings or communications regarding our business
or results, and we do not undertake to address how any of these factors may have
caused changes to discussions  or information  contained in previous  filings or
communications.  In  addition,  any of the  matters  discussed  below  may  have
affected  our past  results and may affect  future  results,  so that our actual
results  may  differ  materially  from  those  expressed  here  and in  prior or
subsequent communications.

We  experienced   significant   losses  in  fiscal  year  2000  related  to  the
restructuring  of our Texas  operations and may incur  additional  losses in the
future.  We incurred  net losses of  approximately  $199.9  million for the year
ended  December 31, 2000 and $4.6 million for the year ended  December 31, 1999.
We recorded  significant goodwill and fixed asset impairment costs in connection
with  restructuring  plans we  adopted  and  announced  in the first and  second
quarters of 2000 related primarily to our Texas operations. While we are hopeful
that our  strategic  action  plans to turn  around  the  Texas  operations  will
succeed,  there  can be no  assurance  that  this  restructuring  will  lead  to
profitability.

If we are unable to comply with the terms of our credit facility,  our borrowing
costs  could  increase  and  if we  cannot  refinance  or  pay  the  outstanding
indebtedness  under the credit  facility  at  maturity,  our  business  could be
adversely  affected.  On October 31,  1998,  we obtained a $200  million  credit
facility that required us to comply with certain financial ratio covenants.  Due
to the significant  losses sustained in the quarter ended June 30, 2000, we were
not in compliance with the financial covenants.  We entered into an amended $185
million credit  facility with the banks on December 15, 2000. As of December 31,
2000, the credit facility was reduced to $135 million as a result of our payment
of $50 million that we received  from the sale and  leaseback of the majority of
our administrative and clinical  properties in Las Vegas in December 2000 and we
were in  compliance  with the new financial  covenants.  We are required to make
semi-annual  principal payments,  ranging from $2 million to $10 million, on the
credit  facility  starting  in June 2001.  These  payments  result in  permanent
reductions  in the size of the credit  facility.  There is no assurance  that we
will be able to obtain  future  waivers  if we are  unable to meet the  covenant
requirements or to cure a default on a timely basis.  Failure to obtain a waiver
or to cure a default on a timely  basis  could  result in  significantly  higher
borrowing  costs  and/or a demand  for  payment  of the  principal.  The  credit
facility  matures on September  30, 2003 and there is no  assurance  that we can
successfully  refinance or pay this debt when it matures. In addition, the loans
bear interest at a fluctuating rate, which could result in significantly  higher
borrowing costs.





If CII Financial is unable to refinance its outstanding convertible subordinated
debentures,  we may not be able to prevent a default when the debentures  mature
in September 2001. Our wholly-owned subsidiary, CII Financial, Inc., or CII, had
outstanding  convertible  subordinated  debentures  totaling  $47.0  million  at
December 31, 2000. These debentures mature on September 15, 2001 and are general
unsecured obligations of CII only. Sierra has not directly assumed or guaranteed
the repayment of the  debentures  and is limited by our bank credit  facility in
purchasing these debentures or providing funds to CII. CII became a guarantor of
our credit  facility  debt in the third quarter of 2000 and the  debentures  are
subordinated  to our  borrowings  under the  credit  facility.  CII is a holding
company and its only significant asset is its investment in California Indemnity
Insurance  Company.  CII has  limited  sources  of cash  and is  dependent  upon
dividends  from  California  Indemnity.   The  payment  of  dividends  or  other
distributions by California  Indemnity are regulated by the California Insurance
Code.  Under current  regulations,  California  Indemnity  could pay $174,000 in
dividends to CII in 2001 without prior approval by the California  Department of
Insurance.  CII does  not  expect  to have  readily  available  funds to pay the
debentures  when they mature.  In December 2000, CII commenced an exchange offer
in  which it is  offering  to  exchange  all of the  debentures  for cash or new
debentures.  On March 16, 2001, CII announced  that the interest  payment on the
debentures due March 15, 2001 was not being paid. There is a 30-day grace period
on the payment of interest before there is a default.  As of March 20, 2001, the
registration  statement  pertaining  to the  exchange  offer had not yet  become
effective and CII is negotiating  with a group of  institutional  holders of the
debentures. There can be no assurance that CII will be successful in refinancing
these  debentures or that we will be in a position to prevent a default when the
debentures mature.

If  our  reinsurers  do not  perform  their  obligations,  we  would  experience
significant losses.
Reinsurance  contracts  do not relieve us from our  obligations  to enrollees or
policyholders.  At December  31, 2000,  we had over $253 million in  reinsurance
recoverable.  We evaluate the financial  condition of our reinsurers to minimize
our exposure to significant losses from reinsurer insolvencies.  At December 31,
2000,  all of our  reinsurers  were rated A- or better by the A.M. Best Company.
Should these  companies be unable to perform their  obligations  to reimburse us
for ceded losses, we could experience significant losses.

Our reinsurance  coverage for workers'  compensation  policies issued after June
30, 2000 has a much higher  retention of liability,  and covers claims in excess
of $250,000 per occurrence,  compared to our former retention that had a maximum
retention  of liability of $17,000 per  occurrence.  As a result,  we must pay a
substantially  higher  portion  of each  claim  before we have  recourse  to our
reinsurers.  In making this change,  we expect an increase in premiums  retained
after reinsurance, an increase in investment income over time and an increase in
our net loss  ratio.  If the  increase  in our net  losses  and loss  adjustment
expenses  is  greater  than the  offsetting  increase  in  earned  premiums  and
investment  income,  then the  earnings of our workers'  compensation  operating
segment could be adversely affected.

If the competitive  environment in California  continues to adversely affect our
premiums on workers' compensation  insurance policies, our profitability will be
adversely affected. There has been intense price competition in California since
that state  replaced  its minimum  rate law with an open  rating  premium law in
1995, which has resulted in substantial  reductions in premium rates. This price
competition has affected and could continue to affect our profitability. Many of
our competitors  are larger and have significantly greater resources than we do.
Continued price  competition  could reduce our  profitability and may reduce the
earnings of our workers' compensation insurance subsidiaries.

Our premium  rates in California  began to increase  toward the end of 1999 and
continued to show an increasing  upward trend  throughout  2000. While this is a
material positive change, we believe that premium rates may still be below those
charged  prior to the advent of open rating in 1995.  The average  premium  rate
increase on California renewing policies was 26% for the year ended December 31,
2000 and averaged 36% in the last half of the year.  For the first two months of
2001,  we had an average  premium  rate  increase of 42% on renewing  California
policies.  There can be no assurance  that these rate increases will continue or
that  they  are  enough  to  enable  us to  report  a  profit  for our  workers'
compensation operating segment.

Although we intend to  underwrite  each account  taking into  consideration  the
insured's risk profile,  prior loss experience,  loss prevention plans and other
underwriting  considerations,  there  can be no  assurance  that,  even with the
premium rate increases,  we will be able to operate profitably in the California
workers'  compensation  market.  In addition,  there is no assurance that future
workers'  compensation  legislation  will not be adopted in  California or other
states which might adversely affect our results of operations.

If we incur  adverse  development  in our  health  care  payables  and  workers'
compensation loss and loss adjustment expense reserves,  our profitability could
be materially  affected.  In 1999 and 2000, the reserves that we established for
prior periods for both our health care payables and workers'  compensation  loss
and loss adjustment expense reserves developed  adversely or higher than what we
had originally  estimated.  The health care payables had adverse  development of
$11.2 million in 1999 and $30.5 million in 2000. The workers'  compensation loss
and loss adjustment expense reserves had net adverse development of $9.9 million
in 1999 and $23.3  million in 2000.  We establish  reserves for these  operating
segments  using  actuarial  projections,  which are  based,  in part,  on actual
historical data and assumptions regarding future trends. Given the uncertainties
that are inherent in making actuarial  projections,  a range of possible results
are  produced  and we  record  reserves  based on our best  judgment  of what we
believe to be an  appropriate  amount.  While we believe  that our  reserves are
adequate,  we may incur  adverse  loss  development  in the  future  that  could
materially affect our results of operations or financial position.

We depend on key enrollment contracts and changes in or the termination of these
contracts  could  adversely  affect our revenues.  A significant  portion of our
total   revenues  come  from  our  contract  with  the  Health  Care   Financing
Administration,  or HCFA, to provide health care services to Medicare enrollees.
Our contract with HCFA is subject to annual  renewal at the election of HCFA and
requires us to comply with federal health maintenance organization, or HMO, and
Medicare laws and  regulations  and may be terminated if we fail to comply.  The
termination of our Medicare contract could have a material adverse effect on our
business.  In addition,  there have been, and we expect that there will continue
to be, a number of legislative proposals to limit Medicare reimbursements, which
could  adversely  affect  our  profitability.  Future  levels of  funding of the
Medicare program by the federal government cannot be predicted with certainty.

Effective November 1, 1996, our wholly-owned subsidiary,  Health Plan of Nevada,
Inc.,  entered  into a Social  HMO  demonstration  program  contract  with  HCFA
pursuant to which a large portion of our Nevada Medicare risk enrollees  receive
certain expanded benefits.  We receive  additional  revenues for providing these
expanded  benefits and they are determined based on health risk assessments that
have been,  and will  continue to be,  performed on our eligible  Medicare  risk
members.  HCFA might consider adjusting the reimbursement  factor for the Social
HMO members in the future. 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 beyond 2003. If the  reimbursement  for these members  decreases
significantly  and the related benefit changes are not made timely,  there could
be a material adverse effect on our profitability.

Changes  in our  mix of HMO  and  managed  indemnity  business  can  affect  our
profitability.  If more employers  switch to self-funded  health plans or health
products  with higher  medical  care  ratios,  then our  profitability  could be
adversely  affected.  There can be no assurance that we will be able to continue
to renew  existing  members and attract new  members.  Our ability to obtain and
maintain favorable group benefit agreements with employer groups can also affect
our profitability. The agreements are generally renewable on an annual basis but
are subject to termination on 60 days' prior notice.  Although no employer group
accounts for more than 2% of our total revenues,  the loss of one or more of the
larger employer groups could have a material adverse effect upon our business.

For the year ended  December 31, 2000,  military  contract  revenue  represented
approximately 24% of our revenue.  The termination of the TRICARE contract would
have a material adverse effect on our business.  In addition,  we have contracts
to provide health care services to federal employees. The rates charged for such
services are subject to annual reviews and retroactive adjustments,  which could
adversely affect our profitability.

To be  profitable,  we must  obtain  adequate  premiums to keep pace with rising
medical costs.
For the year ended  December 31, 2000,  approximately  62% of our total revenues
were medical premiums,  including capitation payments from HCFA, which represent
fixed monthly  payments for each person enrolled in our health care plans. If we
are unable to obtain  adequate  premiums  because of  competitive  or regulatory
considerations,  we could incur decreased profit margins or significant  losses.
For the year ended December 31, 2000,  approximately  39% of our medical premium
revenues were paid by the federal  government  in  connection  with the Medicare
program.  To the  extent  Medicare  premium  rates do not keep pace with  rising
medical  costs,  our  profitability  could  be  materially  adversely  affected.
Historically,  annual rate  increases  were capped by  legislation  in 1997 to a
maximum of 2%. Legislation enacted in 2000 will increase our Medicare rates by a
minimum of 1%  effective  March 1, 2001.  Our  Medicare  programs are subject to
certain  additional risks compared to commercial  health care programs,  such as
higher medical costs and higher levels of utilization.  While we attempt to base
commercial  premiums at least in part on estimates of future health costs,  many
factors,  such as those discussed  above,  may cause actual health care costs to
exceed those cost estimates reflected in premiums charged.

We also  participate  in the Nevada  Medicaid  program.  Similar to the  federal
Medicare  program,  the state  government  determines the premium levels it will
pay. If the state  government  reduces the premium  levels or does not  increase
premiums to keep pace with our cost  increases  and we are unable to offset them
with  changes  in  benefit  plans,  then our  profitability  could be  adversely
affected.

If we are unable to accurately predict future health care costs and manage these
costs,  our  profitability  could be  adversely  affected.  Much of our  medical
premium  revenue is determined in advance of the actual delivery of services and
related costs  incurred.  Our  profitability  will continue to be dependent,  in
large part,  on our ability to predict and maintain  effective  management  over
health care costs  through,  among other  things,  appropriate  benefit  design,
utilization review and case management programs and our contracting arrangements
with providers,  while providing members with quality health care.  Factors such
as utilization,  new technologies  and changing health care practices,  hospital
costs, pharmacy costs, inflation, epidemics, new mandated benefits or additional
regulations,  inability to establish  acceptable  contracting  arrangements with
providers  and  numerous  other  factors  may affect our  ability to manage such
costs.  There can be no assurance  that we will be  successful  in predicting or
mitigating the effect of any of these factors.

The costs of pharmaceutical products and services have increased faster than the
costs of other medical products and services. Although we attempt to effectively
manage the pharmacy costs for our HMOs and PPOs, there can be no assurances that
we will be able to do so in the face of rapidly rising prices.  Also,  statutory
and  regulatory   changes  may   significantly   alter  our  ability  to  manage
pharmaceutical costs through restricted formularies of products available to our
health plan members.

Medical costs payable reflected in our financial statements include reserves for
incurred but not reported  claims,  or IBNR. We estimate the IBNR using standard
actuarial  methodologies  based  upon  historical  data  including  the  average
interval  between the date  services  are rendered and the date claims are paid,
expected  medical  cost  inflation  and  utilization,   seasonal   patterns  and
fluctuations in membership.  The adequacy of the reserve estimates, which are to
a large  degree based on  judgment,  are  sensitive to our growth and changes in
utilization costs, claims payment patterns and medical cost trends, all of which
may affect our ability to rely on historical  information in making IBNR reserve
estimates. Adverse development of medical cost trends and claim payment patterns
from the  assumptions  used to estimate  reserves  could cause these reserves to
change in the near term.  We believe that our reserves for IBNR have been fairly
estimated;  however,  there can be no assurance  as to the ultimate  accuracy or
completeness  of such  estimates or that  adjustments to reserves will not cause
volatility in our results of operations.

If we  are  unable  to  contract  favorably  with  health  care  providers,  our
profitability  could be adversely affected.  Our profitability is dependent,  in
large part, on our ability to contract favorably with hospitals,  physicians and
other health care providers.  Our contracts with primary providers are generally
renewable  annually,  but certain  contracts may be terminated on 90 days' prior
written  notice by either party.  There can be no assurance that we will be able
to continue to renew such  contracts or enter into new contracts  enabling us to
service our members profitably. We expect that we will be required to expand our
health care provider network in order to service  membership growth  adequately;
however,  there  can be no  assurance  that we will be able to do so on a timely
basis or under favorable terms.

We believe  that we have a favorable  contract  with a major Las Vegas  hospital
company. Due to a shortage of available beds at their facilities, we have had to
place our  members in other  facilities,  at a higher  cost to us.  Should  this
shortage of hospital beds extend over a long period of time,  our  profitability
will be adversely impacted.

Our business could be materially adversely affected if the providers we contract
with under a capitated or discounted  fee-for-service  arrangement are unable to
provide the  contracted  services.  We contract with  hospitals,  physicians and
other  providers of health care and  administrative  services under capitated or
discounted fee-for-service arrangements. Capitated providers are at risk for the
cost of medical care and  administrative  services  provided to our enrollees in
the relevant geographic areas;  however,  we are ultimately  responsible for the
provision of services to our enrollees  should the capitated  provider be unable
to provide the contracted services.  The inability of our capitated providers to
provide  the  contracted  service  could have a material  adverse  effect on our
business.

Our business is subject to substantial  government  regulation and the impact of
this regulation may increase our exposure to lawsuits and/or  penalties or other
regulatory  actions for  non-compliance  or may otherwise  adversely  affect our
business.  The health care  industry in general,  and HMOs and health  insurance
companies in particular, are subject to substantial federal and state government
regulation.  In addition,  our workers' compensation  insurance subsidiaries are
subject primarily to state government regulation.  These regulations,  which may
increase our exposure to lawsuits and/or penalties or other  regulatory  actions
for non-compliance,  include, but are not limited to: cash reserves; minimum net
worth; licensing requirements;  approval of policy language and benefits; claims
payment  practices;  mandatory  products  and  benefits;  provider  compensation
arrangements; patient confidentiality;  premium rates; medical management tools;
dividend payments; and periodic examinations by state and federal agencies. As a
result,  a portion of our HMOs' and  insurance  companies'  cash is  essentially
restricted by various state regulatory or other requirements limiting certain of
our subsidiaries' cash to use within their current operations. State and federal
government   authorities  are  continually   considering  changes  to  laws  and
regulations  that may affect us. Many  states in which we operate are  currently
considering regulations relating to mandatory benefits,  provider  compensation,
disclosure  and  composition of physician  networks.  If such  regulations  were
adopted  by any of the  states  in  which  we  operate,  our  business  could be
materially adversely affected.

As a result of the  continued  escalation of health care costs and the inability
of many individuals to obtain health care insurance, numerous proposals relating
to health  care  reform  have been or may be  introduced  in the  United  States
Congress and state legislatures. Any proposals affecting underwriting practices,
limiting  rate  increases,  requiring  new or  additional  benefits or affecting
contracting  arrangements  (including  proposals to require  HMOs and  preferred
provider organizations,  or PPOs, to accept any health care providers willing to
abide by an HMO's or PPO's contract terms), may make it more difficult for us to
control medical costs and could have a material adverse effect on our business.

The Health  Insurance  Portability  and  Accountability  Act, or HIPAA,  privacy
standards for individually  identifiable health  information,  or privacy rules,
may require us to establish  stringent,  and potentially  costly,  procedures to
protect  an  individual's  health  information.  This will also  apply to health
information we disclose to our business  partners who provide health care to our
members  and  enrollees.  Violations  of these  rules can result in  significant
penalties.  The  implementation  of the HIPAA  privacy rules are scheduled to be
effective in April 2003. At this time, we cannot quantify the cost of compliance
or the impact it will have on our business.  There can be no assurance  that the
costs to implement and to comply will not adversely affect our operating results
or financial condition.

In  addition  to  applicable  laws and  regulations,  we are  subject to various
audits,   investigations  and  enforcement   actions.   These  include  possible
government  actions relating to ERISA,  which regulates insured and self-insured
health coverage plans offered by employers; the Federal Employees Health Benefit
Plan; HCFA, which regulates Medicare programs; federal and state fraud and abuse
laws;  and laws relating to  utilization  management  and the delivery of health
care and the timeliness of payment or reimbursement.  Any such government action
could result in assessment of damages, civil or criminal fines or penalties,  or
other sanctions,  including exclusion from participation in government programs.
In addition, disclosure of any adverse investigation, audit results or sanctions
could  negatively  affect our  reputation  in various  markets  and make it more
difficult for us to sell our products and 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 we seek
to structure our operations to comply with  corporate  practice of medicine laws
in all states in which we operate,  there can be no  assurance  that,  given the
varying and uncertain  interpretations of those laws, we would be found to be in
compliance  with those laws in all states.  A  determination  that we are not in
compliance with applicable  corporate  practice of medicine laws in any state in
which we operate could have a material adverse effect on us if we were unable to
restructure our operations to comply with the laws of that state.

Changes in economic  conditions  can lead to reduced  revenues and higher costs,
which could adversely impact our profitability.  Approximately 58% of our health
care premium revenue is derived from commercial group business.  Severe economic
downturn  conditions  could result in employers  reducing or eliminating  health
care benefits for their  employees.  If we cannot reduce our own operating costs
on a timely basis, our  profitability  can be adversely  impacted.  Our workers'
compensation  operating  segment derives its premium revenues as a factor of the
insured employers'  payroll dollars.  Layoffs and other employment actions which
reduce payroll dollars could result in lower specialty product revenue.  Changes
in market interest rates can affect the amount of investment  income we earn and
the  amount  of  realized  and  unrealized  gains and  losses in our  investment
portfolio.  Changes in the costs to provide  health  care and  at-risk  military
health   care   services,   workers'   compensation   claims  and   general  and
administrative  costs  could  result  in  lower  profitability.  Changes  in our
borrowing  rate can affect the amount of  interest  expense we pay on our credit
facility debt and impact our profitability.

The competitive  environment in which we operate may make it difficult for us to
increase or maintain the  premiums we charge or adversely  impact our ability to
manage costs  effectively.  Managed care  companies and HMOs operate in a highly
competitive environment. We have numerous types of competitors, including, among
others, other HMOs, PPOs,  self-insured employer plans and traditional indemnity
carriers,  many of which have substantially  larger total  enrollments,  greater
financial resources  and offer a  broader range of products  than we do. We have
encountered  the  effects  of  increased  competition  in the  Nevada  and Texas
markets.  Certain competitive  pressures have limited our ability to increase or
in some instances  maintain the premiums charged to certain employer groups. Our
inability to manage costs  effectively  may have an adverse impact on our future
results of  operations  by reducing  profit  margins.  In addition,  competitive
pressures  may also result in reduced  membership  levels or  decreasing  profit
margins and there can be no assurance that we will not incur  increased  pricing
and enrollment pressure from local and national competitors.

Our workers'  compensation  operating  segment also faces  competition from much
larger  insurance  companies and state funds,  who have been in business longer,
offer more diversified lines of insurance  coverage,  and have greater financial
resources and distribution capability than us.

Since our business is concentrated geographically,  adverse changes in the areas
in which we operate could significantly  impact our profitability.  The majority
of our HMO operations are concentrated in southern Nevada and in the Dallas/Fort
Worth area of Texas. Any adverse economic, regulatory or other developments that
may occur in Nevada or Texas may negatively  impact our operations and financial
condition.  In the past, we have attempted to expand our  operations  outside of
southern  Nevada.  These  activities  have met with limited success and, in some
cases,   resulted  in  our  incurring   significant   losses.  The  Kaiser-Texas
acquisition has resulted in significant  operating losses and we have incurred a
substantial  debt balance to fund this  acquisition  and its  operating  losses.
Although  we  believe  that we have  materially  corrected  our Texas  operating
problems and are now more  experienced,  we may incur additional losses in Texas
and any future expansions into other regions may not be successful.

If we fail to qualify for the Nevada home office tax credit,  our tax costs will
increase.
Under  existing  Nevada law, a 50% premium tax credit is generally  available to
HMOs and  insurers  that own and  substantially  occupy home offices or regional
home offices within Nevada. In connection with the settlement of a prior dispute
concerning  the  premium  tax  credit,   the  Nevada   Department  of  Insurance
acknowledged  in November 1993 that our HMO and insurance  subsidiaries  met the
statutory  requirements  to qualify for this tax  credit.  We intend to take all
necessary steps to continue to comply with these  requirements.  The elimination
or  reduction  of the  premium  tax  credit,  or our  failure to qualify for the
premium  tax  credit,  would have a material  adverse  effect on our  results of
operations.

We are  subject  to  litigation  in the  ordinary  course of our  business.  Our
insurance  may not  cover  all our  liabilities  and the cost of  obtaining  the
insurance  coverage  may become  unreasonable.  We are and will  continue  to be
subject to certain types of litigation, including medical malpractice claims and
disputes  pertaining  to our contracts and other  arrangements  with  providers,
employer groups and their employees and individual  members. We maintain general
and professional  liability,  property and fidelity  insurance  coverage and our
multi-specialty  medical group maintains  excess  malpractice  insurance for the
providers presently employed by the group.  Additionally,  we require all of our
other independently  contracted  provider physician groups,  individual practice
physicians,  specialists,  dentists, podiatrists and other health care providers
(with the exception of certain  hospitals  which are  self-insured)  to maintain
professional  liability coverage.  We may incur losses not covered by insurance,
beyond  the  limits  of our  insurance  coverage  for our  affiliates'  employed
physicians and staff, for acts or omissions by other  independent  providers who
do not carry sufficient malpractice coverage or for other acts or omissions.  In
addition,  punitive  damage  awards are  generally  not  covered  by  insurance.
Although we believe that we currently carry adequate insurance, no assurance can
be given that our insurance coverage will be adequate in amount or type, will be
available in the future or that the cost of such insurance will be reasonable.

Any difficulty associated with or failure of our management  information systems
could have a material adverse effect on our business. Our management information
systems  are  critical to our current  and future  operations.  The  information
gathered and  processed by our  management  information  systems  assists us in,
among other things, pricing our services,  monitoring utilization and other cost
factors,  processing  provider  claims,  providing  bills on a timely  basis and
identifying  accounts  for  collection.   We  regularly  modify  our  management
information systems. Any difficulty associated with or failure of these systems,
or any  inability  to expand  processing  capability  or to develop and maintain
networking capability, could have a material adverse effect on our business.

A rating  downgrade  from credit  agencies or insurance  rating  agencies  could
reflect  negatively  on our  reliability  and make it more  difficult  for us to
borrow  funds or to compete  with other  health  care or  workers'  compensation
insurance  companies.  Certain of our  subsidiaries  are  subject to scrutiny by
various  credit  agencies such as Standard & Poor's and Moody's,  insurer rating
agencies such as the A.M. Best Company and Fitch IBCA, Duff & Phelps, as well as
health care rating  agencies that rate the quality of service to members such as
the National Committee for Quality Assurance, or NCQA. Currently, Health Plan of
Nevada has an Accreditation  rating from NCQA. Texas Health Choice, or TXHC, had
an  accredited  rating  from NCQA that  expired in April  2000.  We  voluntarily
postponed  our  accreditation  renewal  process  for TXHC and a  scheduled  site
examination  visit  of  TXHC by the  NCQA  in the  second  quarter  of 2000  was
cancelled.  We expect to reschedule  the site  examination  visit in early 2002,
depending upon the NCQA's availability. A negative rating, or the lack of rating
from such agencies,  could have an adverse effect on our ability to borrow funds
or to  compete  with  other  health  care  or  workers'  compensation  insurance
companies in attracting members and selling policies and, ultimately,  adversely
affect our earnings and share price.

If our TRICARE  contract is terminated or modified by the Department of Defense,
or if health care expenses  exceed  contractual  levels,  or if  adjustments  to
contractual  reimbursements  vary  significantly  from  our  expectations,   our
business could be materially adversely affected.
During the third quarter of 1997, our wholly-owned  subsidiary,  Sierra Military
Health  Services,  Inc.,  was  notified  that it had been  awarded a  multi-year
TRICARE managed care support  contract by the Department of Defense,  or DoD, to
serve  TRICARE-eligible   beneficiaries  in  Region  1.  This  region  includes
approximately  621,000 TRICARE  beneficiaries in 13 northeastern  states and the
District of Columbia.  We began health care delivery under this contract on June
1, 1998. The contract contains five option periods. While we expect to begin our
fourth  option  period on June 1, 2001,  the contract may not be renewed for the
fifth option year.

We subcontract  for health care delivery,  including some of the risk, for parts
of the TRICARE  contract.  TRICARE  contracts are generally issued at low profit
margins.  There can be no assurance that health care expenses or  administrative
expenses will not exceed contractual levels, which could have a material adverse
effect on our results of operations, liquidity and financial condition.

In addition,  the DoD has the unilateral  right to modify or change the contract
to increase or decrease  specifications and associated workload.  We incur costs
and cash outflow  related to these change orders (and recognize  revenue using a
percentage-of-completion  method of accounting)  long before final  negotiations
and payment from DoD. As a result,  we could  experience  health care revenue or
administrative  revenue  reduction  adjustments  or delayed  payments  for prior
periods,  which  could  have  a  material  adverse  effect  on  our  results  of
operations, liquidity and financial condition.

We estimate and record revenues earned in part based on preliminary  statistical
data provided by the DoD that  estimates the  beneficiary  population  currently
eligible  to utilize  our  services.  As the DoD and we  continue  to gather and
analyze  this  data,   adjustments  to  previously  estimated  revenues  may  be
necessary. These adjustments could have a material adverse effect on our results
of operations and financial condition.

Finally,  we receive  monthly cash  payments  equivalent to  one-twelfth  of our
annual  contractual  price with DoD. We accrue  health care revenue on a monthly
basis for any monies owed above our monthly cash receipt, based on the number of
estimated  at-risk  eligible  beneficiaries  and the estimated level of military
direct care system  utilization.  The contractual bid price  adjustment  process
serves to adjust the DoD's monthly  payments to us,  because these  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 our monthly health care payment in addition to
lump sum adjustments for past months. As a result of this "true-up" process, our
business and cash flows could be adversely  affected if the timing and/or amount
of these reimbursements should significantly vary from our expectations.

If we are named as a defendant in managed health care class action lawsuits, our
results  of  operations,  liquidity  and  financial  position  may be  adversely
affected.
A number of companies in the managed health care industry have become
involved in several class action  lawsuits  targeting the conduct of business by
managed health care companies. These complaints seek various forms of relief for
alleged  violations of the Employee  Retirement  Income Security Act of 1974,
the Racketeering Influenced and Corrupt Organizations Act and for alleged
misrepresentations  and  omissions  relating to the adequacy of  disclosures  of
providers'  compensation  arrangements  in literature  that is made available to
actual or prospective members. We are currently not the target of any such class
action.  There  can be no  assurance  that we will not be named in this  kind of
lawsuit  or that the effect of such a lawsuit  will not have a material  adverse
impact on our results of operations, liquidity or financial position.

Power  interruptions  due to power  shortages in California  and the  increasing
power costs could impact our operations. The centralized computer system for our
workers'  compensation  operating segment is located in Northern  California and
was shut down for a short  period of time due to a power  outage.  Our  computer
system is  supported  by an  uninterrupted  power  source that can provide up to
ninety  minutes of battery  power;  however,  it does  require  twelve  hours to
recharge  after each use. We are  upgrading  the  uninterrupted  power source to
provide up to three hours of battery  power.  In the event a power outage occurs
which lasts longer, we may experience data corruption with respect to the claims
and  policy  information  being  used at the  time the  system  shuts  down.  In
addition,  our  employees in all states would be prevented  from  accessing  the
claims and policy processing systems while the system is shut down.

Electrical power costs in general, and especially in Nevada and California,  are
increasing  at a higher rate than the consumer  price index.  Higher power costs
could adversely affect our operations and profitability.

We  depend  on our  management  for our  success  and the  loss of our  founder,
Chairman of the Board and Chief Executive  Officer could have a material adverse
effect on our  business.  Our success has been  dependent to a large extent upon
the efforts of Anthony M. Marlon,  M.D., our founder,  Chairman of the Board and
Chief Executive  Officer,  who has an employment  agreement with us. Although we
believe that the development of our management  staff has made us less dependent
on Dr. Marlon, the loss of Dr. Marlon could still have a material adverse effect
on our business.

We are expanding our Internet e-business services while government regulation of
security  and  privacy  is  increasing.   Failure  to  comply  with   applicable
regulations may adversely affect our ability to expand e-business  services.  We
are implementing  strategies to use the Internet to process certain transactions
with our members and  enrollees,  providers,  customers,  brokers and employees.
Federal and state laws, such as HIPAA,  are increasing  regulatory  oversight of
communications  and  transactions  processed  on the  Internet.  There can be no
assurance that the  encryption and other security  measures we have are adequate
to prevent  unauthorized uses of our web site. Failure to comply with applicable
regulations may adversely affect our ability to expand our e-business services.

The price of our common stock has been  volatile and we cannot  assure you as to
the price at which our common  stock will  trade in the  future.  There has been
significant  volatility  in the market  prices of securities of companies in the
health care  industry,  including the price of our common  stock.  Many factors,
including medical cost increases, research analysts' comments,  announcements of
new legislative and regulatory proposals or laws relating to health care reform,
investor  expectations,  the trading volume of our common stock,  litigation and
general economic and market conditions,  will influence the trading price of our
common  stock.  Accordingly,  there can be no assurance as to the price at which
our Common Stock will trade in the future.

We do not plan on paying  dividends  on our  common  stock  for the  foreseeable
future.

We have not paid or  declared  any cash  dividends  on our  common  stock  since
inception and we anticipate that future earnings will be retained to finance the
continuing development of our business for the foreseeable future.
