                  SIERRA HEALTH SERVICES, INC. AND SUBSIDIARIES

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


     1. The accompanying unaudited financial statements include the consolidated
accounts of Sierra Health Services, Inc. ("Sierra", a holding company,  together
with its subsidiaries,  collectively  referred to herein as the "Company").  All
material  intercompany  balances and transactions  have been  eliminated.  These
statements  have  been  prepared  in  conformity  with  the  generally  accepted
accounting   principles   used  in  preparing  the  Company's   annual   audited
consolidated  financial statements but do not contain all of the information and
disclosures  that  would be  required  in a complete  set of  audited  financial
statements.  They should,  therefore,  be read in conjunction with the Company's
annual audited  consolidated  financial statements and related notes thereto for
the years ended  December 31, 1997 and 1996. In the opinion of  management,  the
accompanying  unaudited condensed  consolidated financial statements reflect all
adjustments,  consisting only of normal and recurring adjustments, necessary for
a fair presentation of the financial results for the interim periods presented.

     2. On June 5,  1998,  the  Company's  subsidiary,  HMO  Texas,  L.C.  ("HMO
Texas"),  entered into definitive agreements to acquire certain assets of Kaiser
Foundation  Health  Plan  of  Texas  ("Kaiser"),  a  health  plan  operating  in
Dallas-Forth  Worth with  approximately  120,000 members and Permanente  Medical
Association of Texas ("Permanente"),  a 150 physician medical group operating in
that area.  The  purchase  price was $129  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  encompassing  more than 500,000  square feet. The purchase price may
increase by $30 million over three years if certain growth, member retention and
accreditation goals are met by the health plan.

         Sierra  is  assuming  no prior  liabilities  for  malpractice  or other
         litigation,  or for any  unanticipated  future  adjustments  to  claims
         expenses for periods prior to closing. The transaction will be financed
         with bank debt.  The  transaction  has been  approved  by the Boards of
         Directors of Kaiser and the Company.  Subject to applicable  regulatory
         approvals and other closing conditions,  the transaction is expected to
         close no later than October 31, 1998.

3.       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.

4. The following tables provide a  reconciliation  of basic and diluted earnings
per share ("EPS"):

         130,  "Reporting  Comprehensive  Income"  which  requires  companies to
         classify  items of other  comprehensive  income  by their  nature  in a

         of  unrealized   holding   gains  and  losses  on  available   for-sale
         investments,  net of taxes,  arising  during the period,  adjusted  for
         gains and losses included in net income.

6.       During  1997  the   Financial   Accounting   Standards   Board   issued
         "Disclosures  about Segments of an Enterprise and Related  Information"
         ("FAS 131").  FAS 131 is effective  for fiscal  years  beginning  after
         December  31,  1997;  however,  the  statement  need not be  applied to
         interim  statements  in  the  initial  year  of  application.  FAS  131
         establishes   additional  standards  for  segment  disclosures  in  the
         financial statements.  Management has not determined the effect of this
         statement on its financial statement disclosure.

         In March 1998,  the  Accounting  Standards  Executive  Committee of the
         American  Institute of Certified Public Accountants issued Statement of
         Position  98-1  ("SOP  98-1"),  "Accounting  for the Costs of  Computer
         Software  Developed For or Obtained For Internal  Use." Under SOP 98-1,
         effective for years beginning after December 15, 1998, certain computer
         software  costs are required to be  capitalized  and amortized over the
         software's  estimated  useful life. The Company will adopt SOP 98-1 for
         the fiscal year  ending  December  31,  1999 and does not believe  this
         statement 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

     ITEM 2.  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  Condensed  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  Quarterly  Report on Form 10-Q
should be considered in connection with certain cautionary  statements contained
in the Company's  Current  Report on Form 8-K dated March 19, 1998  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 from those  expressed  in any  projected,  estimated  or  forward-looking
statements relating to the Company.

Results of  Operations,  three  months  ended June 30,  1998,  compared to three
months ended June 30, 1997.

The Company's total operating  revenues for the three months ended June 30, 1998
increased approximately 38.7% to $244.5 from $176.3 million for the three months
ended June 30, 1997. The increase was primarily due to military contract revenue
of $41.9 million and an increase in premium revenue of $18.0 million. During the
fourth  quarter of 1997  Sierra  Military  Health  Services,  Inc.  ("SMHS"),  a
wholly-owned  subsidiary of the Company,  began the implementation  phase of its
TRICARE  contract.  The military  contract  revenue is a result of the continued
implementation  of that contract as well as health care delivery  which began on
June 1, 1998.  The operating  margin for SMHS was 4.3% for the current  quarter.
With health care delivery starting in June 1998,  operating margins for SMHS are
expected to decrease in future quarters.

Medical premium revenue from the Company's HMO and managed  indemnity  insurance
subsidiaries  increased $18.0 million, or 14.3%. The increase in premium revenue
reflects a 5.9%  increase in member  months (the number of months of each period
that an individual  is enrolled in a plan).  Medicare  member  months  increased
19.6% 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 5% for its HMO  commercial  groups and in excess of 10% for
its managed  indemnity  commercial  groups.  The Company also  realized a slight
increase  in its  capitation  rate  established  by the  Health  Care  Financing
Administration  ("HCFA").  Approximately  75% 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 $3.6 million,  or 9.8%, for the three months
ended June 30, 1998 compared to the same  three-month  period in the prior year.
The increase was due to revenue  growth in the workers'  compensation  insurance
operation  offset in part by a decrease in  administrative  services  revenue of
$900,000 due primarily to the termination of the Company's workers' compensation
administrative  services  contract  with the State of Nevada.  Professional  fee
revenue increased approximately $3.6 million primarily due to the acquisition of
the  operations  of  two  medical  clinics  in  southern  Nevada.   In  addition
approximately  $1.1 million of the increase in  professional  fees is due to the
operations  of Total Home Care,  Inc.  ("THC").  THC was  acquired  in the third
quarter of 1997 and provides home infusion, oxygen and durable medical equipment
services  in  Nevada  and  Arizona.   Investment  and  other  revenue  increased
approximately  $1.1  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.

     ITEM 2.  MANAGEMENT'S  DISCUSSION  AND ANALYSIS OF FINANCIAL  CONDITION AND
RESULTS OF OPERATIONS (continued)

Results of  Operations,  three  months  ended June 30,  1998,  compared to three
months ended June 30, 1997 (continued).

Medical  expenses as a  percentage  of medical  premiums and  professional  fees
("Medical  Loss  Ratio")  increased  from 76.7% to 77.4%.  The  increase  in the
medical loss ratio was due to an increase in Medicare members as a percentage of
fully-insured  members,  continued  expansion in Texas which has higher  medical
expenses 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.  Specialty  product  expenses  increased  $3.2 million,  or 8.7%,  due
primarily  to  the  9.8%  increase  in  specialty   product  revenue   discussed
previously.  Specialty  product revenue and expense is primarily  related to the
workers' compensation insurance business.

The combined ratio for the workers'  compensation  insurance  business was 99.6%
compared to 101.7% for the comparable  prior year period.  The reduction was due
to a 225 basis point decrease in the expense ratio which was offset  slightly by
a 12 basis point increase in the loss ratio.  The reduction in the expense ratio
was  primarily  due to a larger net earned  premium.  The dollar amount of those
expenses that are not a direct function of premium  revenues were  substantially
the same between the periods. 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 as well as net favorable
loss  development on prior  accident years totaling $2.6 million,  which was the
same as the  comparable  prior  year  period.  There  can be no  assurance  that
favorable  development,  or the magnitude thereof,  will continue in the future.
The losses and loss adjustment expense ratio for the three months ended June 30,
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.

General,  administrative and marketing ("G&A") costs increased $3.9 million,  or
16.9%, compared to the second quarter of 1997. As a percentage of revenues,  G&A
costs for the second  quarter of 1998  decreased  to 11.0% from 13.1% during the
comparable period in 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.  Of the $3.9 million
increase in G&A,  $1.1  million  consisted  of  increased  compensation  expense
resulting primarily from additional  employees  supporting expanded services and
new benefit  programs for management.  Broker,  third-party  administration  and
premium  tax  expenses  increased   approximately   $600,000  due  to  increased
membership.  The remaining G&A increase is due to additional expenses in several
areas including an increase in depreciation of $400,000. The Company markets its
products primarily to employer groups,  labor unions and individuals enrolled in
Medicare through its internal sales personnel and independent insurance brokers.
Such brokers receive commissions based on the premiums received from each group.
The  Company's  agreements  with its member groups are usually for twelve months
and are subject to annual  renewal.  For the quarter  ended June 30,  1998,  the
Company's ten largest  commercial  HMO employer  groups were, in the  aggregate,
responsible  for less  than 10% of its  total  revenues.  Although  none of such
employer  groups  accounted for more than 2% of total  revenues for that period,
the loss of one or more of the larger  employer  groups  could,  if not replaced
with  similar  membership,  have a  material  adverse  effect  on the  Company's
business.

Interest expense and other increased approximately $400,000 compared to the same
period in the prior year primarily due to the addition of a new mortgage as well
as capital leases for equipment at SMHS.

     ITEM 2.  MANAGEMENT'S  DISCUSSION  AND ANALYSIS OF FINANCIAL  CONDITION AND
RESULTS OF OPERATIONS (continued)

Results of  Operations,  three  months  ended June 30,  1998,  compared to three
months ended June 30, 1997 (continued).

For the period,  the Company recorded  approximately $4.4 million of tax expense
for an  effective  tax rate of 25.9%  compared to 24.0% in 1997.  The  Company's
current low operating tax rate is primarily a result of taxpreferred 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  in  future  periods  after  the  remaining  valuation
allowances for net operating loss carryforwards are utilized.

Net income for the three  months ended June 30, 1998  increased  $2.0 million or
18.8%, compared to the three months ended June 30, 1997.

Results of  Operations,  six months ended June 30, 1998,  compared to six months
ended June 30, 1997.

The Company's  total  operating  revenues for the six months ended June 30, 1998
increased  approximately  31.1% to $455.0 from $346.9 million for the six months
ended June 30, 1997. The increase was primarily due to military contract revenue
of $60.4  million  and an  increase  in premium  revenue of $33.5  million.  The
military  contract  revenue is a result of the continued  implementation  of the
TRICARE contract as well as one month of health care delivery.

Medical premium revenue from the Company's HMO and managed  indemnity  insurance
subsidiaries  increased $33.5 million, or 13.5%. The increase in premium revenue
reflects a 6.5% increase in member  months.  Medicare  member  months  increased
19.3% 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 5% 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 HCFA.  Approximately  75% 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 $5.1 million,  or 7.1%, for the six months
ended June 30, 1998 compared to the same six-month period in the prior year. The
increase  was due to  revenue  growth  in the  workers'  compensation  insurance
operation  offset in part by a decrease in  administrative  services  revenue of
$2.3  million  due  primarily  to  the  termination  of the  Company's  workers'
compensation   administrative  services  contract  with  the  State  of  Nevada.
Professional fee revenue increased  approximately  $7.0 million primarily due to
the acquisition of the operations of two medical clinics in southern Nevada.  In
addition  approximately $1.9 million of the increase in professional fees is due
to the operations of THC.  Investment and other revenue increased  approximately
$2.1 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.

The medical  loss ratio  increased  from 76.7% to 77.1% for the six months ended
June 30, 1998  compared to the prior  period.  The  increase in the medical loss
ratio  was  due  to  an  increase  in  Medicare   members  as  a  percentage  of
fully-insured  members,  continued  expansion in Texas which has higher  medical
expenses 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.  Specialty  product  expenses  increased  $4.8 million,  or 6.7%,  due
primarily  to  the  7.1%  increase  in  specialty   product  revenue   discussed
previously. Specialty product revenue and expense is

RESULTS OF OPERATIONS (continued)

Results of  Operations,  six months ended June 30, 1998,  compared to six months
ended June 30, 1997 (continued).

primarily related to the workers' compensation insurance business.

The combined ratio for the workers'  compensation  insurance business was 101.0%
compared to 103.1% for the comparable  prior year period.  The reduction was due
to a 159 basis point decrease in the expense ratio and a 45 basis point decrease
in the loss ratio.  The  reduction in the expense  ratio was  primarily due to a
larger net earned  premium.  The dollar amount of those  expenses that are not a
direct  function of premium  revenues  were  substantially  the same between the
periods.  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 as well as net favorable loss development on prior
accident years totaling $4.5 million  compared to net favorable loss development
of $4.4 million for the comparable prior year period.  There can be no assurance
that  favorable  development,  or the  magnitude  thereof,  will continue in the
future.  The losses and loss  adjustment  expense ratio for the six months ended
June 30, 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.

G&A costs increased $7.1 million, or 15.8%,  compared to the first six months of
1997.  As a  percentage  of  revenues,  G&A  costs  for the six  months  of 1998
decreased to 11.5% from 13.0% during the comparable period in 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.  Of the $7.1 million increase in G&A, $2.4 million  consisted of
increased  compensation  expense resulting  primarily from additional  employees
supporting  expanded  services and new benefit programs for management.  Broker,
third-party  administration  and premium tax  expenses  increased  approximately
$900,000  due to  increased  membership.  The  remaining  G&A increase is due to
additional  expenses in several areas  including an increase in  depreciation of
$600,000.  The Company markets its products primarily to employer groups,  labor
unions  and  individuals  enrolled  in  Medicare,  through  its  internal  sales
personnel and independent  insurance brokers.  Such brokers receive  commissions
based on the premiums  received from each group.  The Company's  agreements with
its  member  groups are  usually  for  twelve  months and are  subject to annual
renewal.  For the six months  ended June 30,  1998,  the  Company's  ten largest
commercial HMO employer groups were, in the aggregate, responsible for less than
10% of its total revenues.  Although none of such employer groups  accounted for
more than 2% of total  revenues for that period,  the loss of one or more of the
larger employer groups could,  if not replaced with similar  membership,  have a
material adverse effect on the Company's business.

Interest expense and other increased slightly compared to the same period in the
prior year primarily due to the acquisition of new debt.

     ITEM 2.  MANAGEMENT'S  DISCUSSION  AND ANALYSIS OF FINANCIAL  CONDITION AND
RESULTS OF OPERATIONS (continued)

Results of  Operations,  six months ended June 30, 1998,  compared to six months
ended June 30, 1997 (continued).

For the period,  the Company recorded  approximately $8.6 million of tax expense
for an  effective  tax rate of 25.7%  compared to 24.0% in 1997.  The  Company's
current low operating tax rate is primarily a result of taxpreferred 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  in  future  periods  after  the  remaining  valuation
allowances for net operating loss carryforwards are utilized.

Net income  for the six months  ended June 30,  1998  increased  $12.8  million,
compared  to the six months  ended June 30,  1997.  Excluding  the effect of the
merger related expenses, net income increased $4.4 million, or 21.7% compared to
the same period in the prior year.

Liquidity and Capital Resources

The Company's  cash flow from operating  activities  during the six months ended
June 30, 1998 resulted primarily from $24.7 million of net income,  $8.5 million
in  depreciation  and  amortization  and $3.2 million in provision  for doubtful
accounts  offset by a $32.5  million net change in assets and  liabilities.  The
decrease in cash flow  resulting from the change in assets and  liabilities  was
primarily due to an increase in accounts  receivable  and a decrease in unearned
premium revenue.  The increase in accounts  receivable  resulted  primarily from
work performed in conjunction  with the Region 1 TRICARE  contract for which the
Company  had  not  been  paid  as  of  June  30,  1998.  The  Company   received
approximately  $28.8 million of this  receivable  in July 1998.  The decrease in
unearned  premium  revenue  resulted  primarily  from the early  receipt  of the
subsequent month's HCFA Medicare capitation payment as of December 31, 1997.

The $27.4 million used for investing and financing activities since December 31,
1997 consisted of a $19.1 million net increase in investments, and $17.2 million
in  capital   expenditures  for   construction   costs  associated  with  office
facilities,   furniture  and  equipment  for  the  newly  constructed  six-story
headquarters building,  continued  implementation of three new computer systems,
computer and medical equipment, and other capital needs to support the Company's
growth.  The Company  received $15.5 million from new debt primarily  related to
financing  for the newly  constructed  headquarters  building  offset in part by
$12.7 million used for the reduction of debt,  including an $8.0 million payment
on the Company's line of credit.  In July 1998, the Company repaid an additional
$9.0  million on its line of  credit.  The  remaining  $92.0  million  available
balance of the line of credit as of July 31,  1998,  may be used for  additional
working capital, if necessary.  In addition the Company received $4.7 million in
connection  with the sale of stock  through the  Company's  stock plans and $1.4
million in connection with the sale of THC's Arizona operations.

On June 5, 1998, HMO Texas entered into signed definitive  agreements to acquire
certain assets of Kaiser and Permanente in Dallas, Texas. The purchase price was
$129 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 may increase by $30 million
over three years if certain growth, member retention and accreditation goals are
met by the health plan.  Sierra is assuming no prior liabilities for malpractice
or other  litigation,  or for any  unanticipated  future  adjustments  to claims
expenses for periods  prior to closing.  The  transaction  will be financed with
bank debt. Subject to applicable  regulatory and other closing  conditions,  the
transaction is expected to close by the end of October 1998.

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

RESULTS OF OPERATIONS (continued)

reserve requirements.  The HMO and insurance  subsidiaries had restricted assets
on deposit in various states totaling $17.2 million as of June 30, 1998. The HMO
and  insurance  subsidiaries  must also meet  requirements  to maintain  minimum
stockholder's  equity,  on a  statutory  basis,  ranging  from  $500,000 to $5.2
million.  Of the cash and cash  equivalents held at June 30, 1998, $62.3 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
available  on an  unrestricted  basis.  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 National Association of Insurance  Commissioners (the "NAIC") has undertaken
an  initiative  that would impose new minimum  capitalization  requirements  for
HMOs,  health  care  insurance  entities  and other  risk  bearing  health  care
entities.  If those  capitalization  requirements  are  adopted,  certain of the
Company's  subsidiaries  may have increased  minimum capital  requirements.  The
Company does not believe that any such required  increase in the amount of funds
to be contributed to the subsidiaries will be material.

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  more  than  600,000  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  will  result in a total of  approximately  $150.0 to  $200.0  million  of
revenue for the five-month  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.  The TRICARE  Management  Activity  ("TMA") along with the Company,  has
filed a motion requesting the GAO reconsider its recommendation. If the GAO does
not change its recommendation and the TMA follows the recommendation,  there are
several possible  outcomes,  including  litigation.  While it is not possible to
predict the outcome,  the Company  anticipates  that it will continue to provide
health care under the  contract for a currently  undetermined  amount of time if
the TMA and the Company are unsuccessful in their reconsideration request.

The Company is in the process of modifying or replacing its computer systems and
applications to accommodate the "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.  The Company currently expects to complete
all  material   replacements  or  modifications  of  its  computer  systems  and
applications  sufficiently  in  advance  of the Year 2000 to allow for  adequate
testing so as not to have any material  negative impact on its  operations.  The
Company is in the process of  implementing  three major  systems at an estimated
cost of  $25.0  million  to  $30.0  million.  These  systems  will be Year  2000
compliant.  The Company is expensing the costs to make modifications to existing
computer  systems as incurred.  Management  currently  estimates  the  remaining
modification  costs to be  approximately  $3.0  million to $5.0 million over the
next two years. 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 inability of the Company to
timely complete its Year 2000  modifications and replacements,  or the inability
of companies with which the Company does business to timely  complete their Year
2000  modifications,  could have a material effect on the Company's  operations.
During  the first six  months of 1998,  the  Company  spent  approximately  $7.0
million on both system implementations and Year 2000 items.

     The Company  has a 1998  capital  budget of  approximately  $50.0  million,
primarily for computer hardware and

software, furniture and equipment for the newly constructed 180,000 square foot,
six-story  corporate  headquarters  building,  and other requirements due to the
Company's projected growth and expansion. Excluding the acquisition from Kaiser,
which will be financed with bank debt,  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.  Excluding the acquisition from
Kaiser, 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.

ITEM 1.        LEGAL PROCEEDINGS


On March 18, 1997, the Company  announced it had terminated its merger agreement
with Physician  Corporation of America ("PCA").  The original agreement had been
entered into in November  1996. On March 18, 1997,  prior to  termination of the
merger  agreement,  PCA filed a lawsuit against the Company in the United States
District  Court for the  Southern  District of Florida (the  "District  Court"),
seeking,  among other things,  specific  performance of the merger agreement and
monetary  damages  in excess of $20  million.  The  lawsuit  has been  dismissed
(without prejudice to PCA's claims) for failure to join an indispensable  party.
On March 27, 1997, the Company  commenced a lawsuit  against PCA in the Court of
Chancery of the State of Delaware.  On July 31, 1998, the Company filed a Second
Amended Complaint alleging,  among other things, breach of the merger agreement,
negligent  misrepresentation,  common law fraud and equitable fraud, and seeking
monetary  damages and other remedies.  The Company intends to vigorously  pursue
all  remedies  available  to it,  however,  there can be no  assurance  that the
Company will prevail in such litigation.

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,
claims by providers  for payment for medical  services  rendered to HMO members.
Also included in such  litigation are claims for dividends and claims denials in
the  workers'  compensation  division  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.

the  representations and warranties of Seller are not true and correct as of the
Closing Date,  then Buyer shall be entitled to  indemnification  for any and all
losses   arising   therefrom  in  accordance   with  Paragraph  3.6,  but  shall
nevertheless be obligated to conclude the transactions  contemplated hereby. The
consummation  of the  transactions  under  this  Agreement  by Buyer  shall  not
constitute  a waiver  of  Buyer's  rights to  indemnification  for a breach of a
representation or warranty



                                                        12

     3.2  Representations  and  Warranties of Buyer.  As of the Execution  Date,
Buyer represents and warrants to Seller as follows:

         (a)  Organization  and  Good  Standing.  Buyer is a  limited  liability
company duly organized,  validly existing and in good standing under the laws of
the State of Texas.  Buyer is authorized  under state law to conduct business in
the State of Texas.

         (b) Buyer's Authority and No Breach.  Buyer has all requisite corporate
power and corporate  authority to enter into this Agreement and all of the other
agreements contemplated hereby, and to consummate the transactions  contemplated
hereby. The execution and delivery of this Agreement and the consummation of the
transactions  contemplated  hereby have been duly  authorized  by all  necessary
corporate  action on the part of Buyer.  This Agreement and each other agreement
contemplated   hereby   constitute  valid  and  binding   agreements  of  Buyer,
enforceable  against  Buyer in all material  respects in  accordance  with their
respective terms,  except insofar as enforcement may be limited by insolvency or
similar laws  affecting the  enforcement  of creditors'  rights in general,  and
except  as  enforceability  may be  limited  by  general  principles  of  equity
(regardless  of whether such  enforceability  is  considered  in a proceeding in
equity or at law.)

         (c) No Brokers or Finders. No broker or finder is involved on behalf of
Buyer or any  affiliates of Buyer in connection  with the sale of the Properties
nor may any broker or finder involved on behalf of Buyer claim any commission on
account of the sale of the Properties. The parties acknowledge that Bear Stearns
has been engaged by Buyer as a financial  advisor to Buyer, and the fees of Bear
Stearns shall be paid for by Buyer in accordance with the HMO Agreement.

         (d) Buyer's Consents.  Except as set forth in the HMO Agreement,  Buyer
is not  required to obtain the consent or  approval  of any  government  agency,
department  or other  government  body to  perform  its  obligations  under this
Agreement.

         (e) No Untrue  Representation  or Warranty.  To Buyer's  knowledge,  no
representation  or warranty by Buyer in this  Agreement,  nor any  statement  or
certificate  furnished  or to be  furnished  to  Seller  pursuant  hereto  or in
connection with the transactions  contemplated hereby,  contains or will contain
any untrue statement of a
material fact.

         (f)  Representations  and  Warranties  True  and  Correct  at  Closing;

as of the Closing Date, or describing  the manner in which such  representations
and  warranties  are not true and  correct.  If any of the  representations  and
warranties of Buyer are not true and correct as of the Closing Date, then Seller
shall be  entitled  to  indemnification  for any and all losses as  provided  in
Paragraph  3.6. The  consummation  of the  transactions  under this Agreement by
Seller shall not constitute a waiver of Seller's rights to indemnification for a
breach of a representation or warranty provided for in this Paragraph.

         3.3 Survival of Provisions. The representations, warranties, covenants,
agreements, indemnities, terms and provisions contained herein shall survive the
Closing for a term of five (5) years and shall not be deemed to have been merged
with or into the
Deeds.

     3.4 Operations  Pending  Closing.  From the date hereof through the Closing
Date, Seller agrees as follows:

         (a) Seller will  manage,  operate,  repair and maintain the Property in
the same manner as it operated  the  Property  prior to the date hereof and will
keep the  Property  in its  present  state of repair  subject to normal wear and
tear,  exercising  the  same  degree  of care  in such  matters  as  Seller  has
previously  exercised  and in compliance  with  Applicable  Laws and  Applicable
Environmental  Laws. Except for the sale or use of operating  inventories in the
ordinary  course of  business,  Seller  shall not  remove  any item of  Personal
Property from the Property without  replacing the same with property of equal or
greater value.

         (b) Except as  permitted  by the HMO  Agreement,  Seller will not enter
into any renewal, extension, modification or replacement of any existing service
contract or enter into any new employment, maintenance, service, supply or other
agreement  relating to the Property  without the express  written  permission of
Buyer.

         (c) Without the prior  written  consent of Buyer,  Seller shall not (i)
enter into any new leases or  occupancy  agreements  for space at the  Property,
(ii)  modify,  amend,  terminate,  renew,  extend or waive any rights  under any
existing Lease,  (iii) apply any rental security  deposits  against sums payable
under any Lease,  (iv) grant any concession,  rebate,  allowance or free rent to
any tenant for any  period,  or (v) accept the  surrender  of or  terminate  any
Lease.  Notwithstanding  the foregoing,  to the extent  available at the time of

feet, at Seller's option, of currently built-out  administrative space in either
North Point I (9229 LBJ Freeway,  Dallas,  Texas) or Hillcrest (12720 Hillcrest,
Dallas,  Texas) (but in no event less than 5,000  square feet) for not more than
18 months for gross rent equal to $11.00 per foot per year (Seller shall pay for
electricity).  The lease,  if entered  into,  shall be executed and delivered at
Closing,  shall  allow  Seller  to  release  space  back to  Buyer  as  Seller's
operations wind down, in 1,000 square foot increments,



                                                        14

at months end, and shall contain such other terms as are typically  including in
third party leases at the same  building.  In addition,  Seller shall attempt to
satisfy  Seller's   transition  space   requirements  from  Centex  Real  Estate
Corporation  ("Centex")  first and shall have the option to sublease any portion
of the  premises now leased to Centex and not  subleased  to third  parties upon
such terms as Seller may deem  appropriate  as between Centex and Seller without
modification  of the terms of the Lease  Agreement now in effect  between Centex
and Seller covering  premises located in North Point I. There are  approximately
15,000  square feet of space not  subleased  by Centex to third  parties at this
time.  Buyer  agrees not to compete for the Centex  space until  Seller's  space
requirements have been satisfied.

         (d) Seller  will  continue to  self-insure  for all  existing  fire and
casualty liability, which self-insurance shall inure to the benefit of Buyer.

         (e) Seller  shall  perform  its  obligations  when due  pursuant to the
Leases, including, without limitation, any maintenance or repair of the Property
to be performed by Seller as landlord  under the Leases;  and except as provided
this Agreement,  all construction of tenant improvements and other work required
to be  performed  under any Lease  entered  into prior to the  Closing  shall be
completed, satisfied and paid in full by Seller prior to Closing.

         (f) Buyer or representatives of Buyer shall have access to the Property
during normal  business  hours if Buyer  notifies  Seller in writing at least 48
hours in advance of the time Buyer desires access to the Property.

         (g) Seller  will not cause any action to be taken which would cause any
of the  representations  or  warranties  made by Seller in this  Agreement to be
false on or as of the  Closing  Date.  Seller  shall  promptly  notify  Buyer in
writing of the  occurrence  of any event or condition  which occurs prior to the
Closing Date which  causes an adverse  change in any of the  representations  or
warranties made in Article III of this Agreement.

         (h) Seller shall give Buyer  prompt  notice of the  institution  of any
litigation,  arbitration or administrative proceeding or condemnation proceeding
of which it becomes aware prior to the Closing Date involving Seller relating to
the Real Property.

         (i) Seller shall make best efforts to obtain  estoppel  certificates in
the form of  Exhibit I  attached  hereto  (the  "Estoppels")  and  deliver  said
Estoppels to Buyer on or before the Closing  Date. If Seller is unable to obtain
such Estoppels, Seller may substitute a certificate from Seller substantially in
the form of the Estoppels.

         3.5  Communications.  Between the Execution  Date and the Closing Date,
and unless otherwise  specifically  authorized in this Agreement,  Buyer may not

Services for Seller,  and George Tomberlin,  Senior Counsel for Seller, or their

Paragraph shall preclude either Buyer or Seller from  communicating  as it deems
advisable with its own subscribers,  government  regulators,  service providers,
employees,  vendors,  shareholders,  suppliers,  and third party  contractors as
required by law in the ordinary course of business, or prohibit Buyer from doing
its  due  diligence  review,  including  inspections  with  surveyors,  property
inspectors,  environmental  consultants  and title officers and the obtaining of
zoning and other similar  property related  information from local  governmental
authorities.  In  no  event  shall  either  party  cause  any  oral  or  written
communication  to be issued relating to this  transaction  which  disparages any
other party or its affiliates,  unless required by law.  Communications with the
media  shall be  subject  to the joint  work plan to be  developed  by Buyer and
Seller pursuant to the HMO Agreement.

                  representation, warranty, covenant or agreement made by Seller
                  in this  Agreement,  or in any  other  agreement  executed  in
                  connection herewith.

         (b)  Indemnification by Buyer.  Subject to the limitations of Paragraph
3.6(c) below,  Buyer shall indemnify and hold harmless Seller and its respective
officers,  directors,  employees,  agents  and  affiliates,  against  any losses

         (c) Limitation. The indemnification rights and obligations set forth in
this  Paragraph  3.6 shall  survive the Closing and shall  expire as provided in
Paragraph 3.3; provided,  however,  that with respect to claims notified in good
faith to the indemnifying party prior to the expiration of the indemnity rights,
the parties'  obligations  with respect to its indemnity  rights and obligations
shall continue in effect until payment or other resolution of such claims.  Each
party's  liability  hereunder  shall be limited to actual  damages  and no party
shall be  liable  to any  other  party  hereunder  for  special,  consequential,
incidental, punitive or other damages. If a party is entitled to indemnification
under the specific indemnification  provisions of this Agreement with respect to
a particular  claim,  then such  indemnification  shall be such party's sole and
exclusive remedy;  provided however,  indemnification  shall not be the sole and
exclusive remedy under the documents,  agreements and certificates  delivered at
Closing pursuant to Paragraph 5.2 hereof.  This subparagraph shall be subject to
and limited by the  provisions  contained  in Sections  11.4 and 11.6 of the HMO
Agreement, which are incorporated herein by reference.

Affiliate")  hereby  irrevocably and  unconditionally  agrees to cause Seller to
fully  perform its  obligations  under this  Agreement in a timely  manner,  and

Seller  in  accordance  with its  terms.  The  foregoing  guarantee  includes  a
guarantee of the immediate  payment when due of all amounts for which Seller may
at any time be liable on account  of the  Agreement.  Buyer  may,  at it option,
proceed  directly  against  Seller's   Affiliate  for  the  performance  of  any
obligations of Seller hereunder or for any amounts which may be recoverable as a
result of any misrepresentation, breach of warranty, breach of covenant or other
cause of Seller's  liability  under this  Agreement,  without any requirement to
proceed against Seller either prior to or concurrently  with proceeding  against
Seller's  Affiliate.  Seller's Affiliate further agrees that its guarantee shall
continue in effect notwithstanding any modification,  extension, waiver or other
changes in or under this Agreement or any guaranteed obligation of any other act
or thing which might  otherwise  operate as a legal or equitable  discharge of a
guarantor.  Seller's Affiliate hereby waives all special suretyship defenses and
notice requirements.

     (b) Buyer's  Guarantor.  Sierra Health Services,  Inc.  ("Buyer's  Parent")

(the "Adjustment Date"):

         (a) Real estate and other ad valorem  taxes,  personal  property or use
taxes,  on the basis of the fiscal  year for which  such  taxes or  charges  are
assessed.  If the actual ad valorem  taxes are not available on the Closing Date

taxes at the  Closing  shall be  estimated  based  upon  reasonable  information
available  to the  parties,  including  information  disclosed  by the local tax
office or other public information,  and an adjustment shall be made when actual
figures are published or otherwise become available; provided, however, that any
prorations  made pursuant to the HMO Agreement shall not be duplicated in making
the prorations hereunder.

         (b) All costs and expenses of operating the Property,  and amounts paid
or payable under the service  contracts  shall be  determined to the  Adjustment

Closing.

         (c) Water and sewer charges, fuel charges,  electricity, gas or utility
charges (including, without limitation, telephone, gas and electricity) shall be
prorated as of the Adjustment  Date, and Seller shall terminate its account (but

Adjustment Date. Buyer shall, prior to the Closing Date, make application to the
providers of such services for the  continuation of such services in the name of
Buyer or its designee. If termination of such accounts on the Adjustment Date is
not feasible,  the meters will be read on or about the  Adjustment  Date and the
Seller  shall be  responsible  for paying the bills for such  services  accruing
prior to the Adjustment  Date and the Buyer shall be responsible for the payment
of all such accounts accruing on or after the Adjustment Date.

         (d) Collected  rents and other sums payable under the Leases which have
accrued  prior to the  Adjustment  Date shall be prorated as of the Closing Date

shall have the right to collect  delinquent  rents directly from a tenant by any
legal  means,  provided  that  neither  party shall be  obligated  to attempt to
collect such delinquent rents, and any recovery,  after the costs of collection,
shall be prorated equitably as of the Adjustment Date.

                                   ARTICLE VI

inoperative



                                                        22

(collectively,  the "Damage"),  by fire, flood, natural elements or other causes
beyond Seller's control, then the following shall apply:

         (a) If the Damage is not Material  (hereinafter  defined),  Buyer shall
proceed to close and purchase the Property as diminished by such Damage, subject
to a reduction in the Purchase Price equal to the cost of repairing or restoring
the Damage, as determined under subparagraph (c) below.

         (b) If the Damage is  Material,  then Buyer,  at its sole  option,  may
elect either (i) to terminate  this  Agreement by written notice to Seller given
at or prior to the Closing, whereupon the Title Company shall immediately return
the Escrow  Deposit to Buyer and, upon Buyer's  receipt  thereof,  neither party
hereto shall have any further rights against, or obligations to, the other under
this Agreement; or (ii) require Seller to agree to close and complete the repair
or restoration of the Damage after the Closing.

         (c) For the purposes of this Paragraph  6.1,  Damage shall be deemed to
be  "Material"  if (i) the  cost of  repairing  the  Damage  equals  or  exceeds
$250,000.  The cost of repairing the Damage shall be determined in the following
manner:  Within 10 days after the Damage occurs,  each party shall  designate an
engineering  firm to act on its behalf,  and the firms designated shall promptly
consult  with  each  other in an  attempt  to  mutually  agree  upon the cost of
repairing  the Damage.  If the firms  cannot agree on the cost within the 10-day
period after they have both been designated,  they shall, within five days after
such  10-day  period,  designate  a  third  engineering  firm,  which  shall  be
instructed  to determine  the cost of repairing  the Damage within 10 days after
its  designation.  The cost of repairing  the Damage as  determined by the third
engineering firm shall be conclusive.

         (d) This  Agreement  shall not be interpreted as including an agreement
by the parties that they shall have the rights and duties  prescribed by Section
5.007 of the Texas Property Code.

         6.2  Condemnation.  If,  prior to the Closing  Date,  all or a material
portion of the Property is taken by, or made subject to,  condemnation,  eminent
domain or other governmental  acquisition  proceedings,  then Buyer, at its sole
option, may elect either:

         (a) To terminate this Agreement by written notice to Seller given at or
prior to the Closing,  whereupon the Title Company shall immediately  return the
Escrow Deposit to Buyer and, upon Buyer's receipt thereof,  neither party hereto
shall have any further rights  against,  or obligations to, the other under this
Agreement; or

         (b) To agree to close  and  deduct  from the  Purchase  Price an amount
equal to any sum paid to  Seller  for such  governmental  acquisition,  in which
event Seller shall assign, transfer and set over to Buyer all of Seller's right,
title and  interest  in and to any  awards  which  may in the  future be made on
account of such governmental acquisition.

         (c)  A  "Material"  taking  shall  be  a  taking  and  the  payment  of
compensation in excess of $5,000,000.

                                    DEFAULTS

         7.1  Default  by  Seller.  In the event  Seller  shall  default  in its
obligation to convey the Real Property to Buyer pursuant to this Agreement,  the
Buyer may, as its sole alternatives,  either (i) enforce specific performance of
this Agreement, or (ii) terminate this Agreement by written notice to Seller and
the Title Company, in which event the Escrow Deposit shall be returned to Buyer,
or (iii) institute suit against Seller for damages.

         7.2 Default by Buyer.  In the event Buyer defaults in its obligation to
purchase the Real Property from Seller pursuant to this  Agreement,  Seller may,
as its sole and exclusive  remedy for such breach,  terminate  this Agreement by
written notice to Buyer and the Title Company, and upon any such termination the
Title Company shall immediately  deliver the Escrow Deposit to Seller,  such sum
being agreed upon as the amount payable by Buyer to Seller as liquidated damages
and in  consideration  of Buyer  having  the  option to refuse to  purchase  the
Property  without any  liability on account of its refusal other than payment of
the Escrow Deposit.

harmless the other from and against any and all liabilities,  claims, demands or

contemplated  hereby,  and any court costs,  attorneys'  fees or other costs and
expenses arising therefrom, insofar as any such liabilities,  claims, demands or
actions are based upon a contract or commitment of the indemnifying party.

         8.5 Entire  Agreement.  This  Agreement  (including  the  Exhibits  and
Schedules) and the other  agreements,  certificates  and documents of Seller and
Buyer  contemplated  herein  constitute the entire agreement between the parties
hereto with respect to the matter hereof, and supersedes all prior agreements or
understandings between the parties. No amendment, alteration, or modification of
this  Agreement   shall  be  valid  unless  in  each  instance  such  amendment,
alteration,  or modification is expressed in a written  instrument duly executed
by the parties hereto.

         8.6  Modification.  Neither this Agreement nor any provision hereof may
be waived, modified, amended, discharged or terminated except as provided herein
or by an instrument in writing signed by the party against which the enforcement
of such waiver, modification, amendment, discharge or termination is sought, and

         8.7 Applicable Law. This Agreement is to be governed by and interpreted

Notwithstanding  the foregoing,  this  Agreement  shall not be assignable by any
party  without  the prior  written  consent of the other,  and any attempt at an
assignment  in violation of this  Paragraph  shall be void ab initio;  provided,
however,  that this  Agreement  may be assigned to an affiliate of Buyer without
Seller's consent.

         8.10 Further  Assurances.  Each party hereto  agrees for the benefit of
the other  parties  hereto to  execute  and  deliver  any  necessary  documents,

(ii) carry out the terms of this Agreement
and the transactions contemplated by this Agreement.

         8.11 Time of Essence.  Time is of the essence of this  Agreement and of
each  covenant and  agreement  that is to be  performed at a particular  time or
within a  particular  period of time.  However,  if the final date of any period
which is set out in any  provision  of this  Agreement  (other  than the Closing
Date) falls on a Saturday,  Sunday or legal holiday under the laws of the United
States or the State of Texas,  then the time of such period shall be extended to
the next date which is not a Saturday, Sunday or legal holiday.

         8.12 Severability.  If any provision of this Agreement is held by final
judgment  of a  court  of  competent  jurisdiction  to be  invalid,  illegal  or
unenforceable, such invalid, illegal or unenforceable provision shall be severed
from the remainder of this Agreement,  and the remainder of this Agreement shall
be enforced. In addition, the invalid,  illegal or unenforceable provision shall
be deemed to be automatically  modified,  and, as so modified, to be included in
this Agreement,  such modification being made to the minimum extent necessary to
render  the  provision  valid,  legal  and  enforceable.   Notwithstanding   the
foregoing,  however,  if the severed or  modified  provision  concerns  all or a
portion of the essential  consideration  to be delivered under this Agreement by
one party to the other, the remaining provisions of this Agreement shall also be
modified to the extent  necessary to adjust  equitably  the parties'  respective
rights and obligations hereunder.

     8.13  Attorneys'   Fees.  If  either  party  defaults  in  its  obligations
hereunder,  the  defaulting  party  shall  pay the  reasonable  attorneys'  fees
incurred by the other party in order to enforce its rights hereunder.

                  8.14  Construction.  Whenever  the  context of this  Agreement
requires, the gender of all words herein shall include the masculine,  feminine,
and neuter,  and the number of all words herein  shall  include the singular and
plural.  All parties to this  Agreement  have been  represented  by counsel and,
accordingly,  this Agreement shall not be construed  strictly for or against any
party hereto. The Schedules and Exhibits attached hereto are incorporated herein

                                         ASSET SALE AND PURCHASE AGREEMENT


     THIS ASSET SALE AND PURCHASE  AGREEMENT  ("Agreement")  is made and entered
into as of this 5th day of June,  1998  ("Execution  Date"),  by and between HMO
Texas, L.C., a Texas limited liability company ("Buyer"),  and Kaiser Foundation
Health Plan of Texas, a Texas non-profit corporation ("Seller").

                                                     RECITALS:

     A. Seller is a Texas  non-profit  corporation  that is exempt from  federal
income taxation under Section 501(c)(3) of the Internal Revenue Code of 1986, as
amended ("Code"). Buyer is a Texas limited liability company.

     B. Seller's business operations are comprised of several business segments,
including  (i) its  operation  in the  State of  Texas  of a health  maintenance
organization  ("HMO  Business"),  (ii) the provision and delivery of health care
services  in the State of Texas (as  distinct  from the  financial  coverage  of
health care services that are part of the HMO Business) ("Delivery System"), and
(iii) the  provision  and  delivery of  pharmacy  services in the State of Texas
("Pharmacy  Business").  The HMO Business, the Delivery System, and the Pharmacy
Business are  collectively  referred to as the  "Business." In addition,  one of
Seller's Affiliates (as herein defined),  Kaiser Permanente Insurance Company, a
California  domiciled  life and  disability  insurer  ("KPIC"),  issues  certain
indemnity  products  in Texas  ("Indemnity  Business")  in support  of  Seller's
Business.

     C. Seller desires to sell,  assign,  and deliver to Buyer, or to arrange or
cause to be sold,  assigned,  and delivered by Seller's Affiliates to Buyer, and
Buyer desires to purchase, accept assignment, and accept delivery from Seller or
Seller's Affiliates, substantially all of the operating assets used by Seller in
the operation of its Business, including, without limitation, (1) the subscriber
agreements ("Subscriber Agreements") and government contracts under which Seller
has agreed to provide or arrange for the provision of health care services to be
delivered to covered  individuals and group enrollees  (including  their covered
spouses and covered  dependents)  under direct pay,  group,  welfare trust,  and
other  plans  or  policies,  and  (2)  certain  provider  agreements  ("Provider
Agreements")  through  which Seller has arranged for health care  services to be
delivered to Members (as hereinafter defined), and certain other property owned,
leased or otherwise used by Seller in the operation of its Business. Each person
enrolled under the Subscriber  Agreements or under  governmental  contracts with
the Health Care  Financing  Administration  ("HCFA") or the Office of  Personnel
Management  ("OPM"),  or Texas and  Non-Texas  Group 3000 Members is referred to
individually as a "Member" or  collectively as "Members." The term  "Affiliates"
shall mean any entity  which  controls,  which is under  control of, or which is
under common  control with,  either Buyer or Seller.  Affiliates of Seller shall
include Kaiser  Foundation  Hospitals  ("KFH") and Kaiser Foundation Heath Plan,
Inc.  ("KFHP").  "Control," as used in the definition of Affiliates,  shall mean
the  possession,  directly  or  indirectly,  of the power to direct or cause the
direction of  management  and policies of another  entity,  whether  through the
authority to elect the board of directors of such entity or otherwise.

Buyer or Buyer's Affiliate. The Insurance and the Assumption Insurance Agreement
including  its  exhibits,  (as  herein  defined)  shall  be  referred  to as the
"Reinsurance Agreements."

("Confidentiality  Agreement") dated March 28 and March 30, 1998,  respectively,
relating to the transactions set forth in this Agreement.

     F. Buyer and Seller wish to set forth the terms and conditions  under which
Buyer will buy and  Seller  will  sell,  or cause to be sold,  the assets of the
Business.

     All annual or periodic ad valorem fees, taxes, assessments, licensing fees,
vehicle  use fees,  and similar  charges  imposed by taxing  authorities  on the
Assets  (collectively,  "Property  Taxes") shall be borne and paid (a) by Seller
for all full tax years or periods ending before the Closing and for that portion
of any tax year or  period  ending  on or  after  the  Closing  from the date of
commencement  of such  year or  period  to the date  immediately  preceding  the
Closing,  and (b) by Buyer for all full tax  years or  periods  beginning  on or
after the  Closing and for that  portion of any tax year or period  ending on or
after the Closing from and  including the Closing to the final date of such year
or period, regardless of when or by which party such Property Taxes are actually
paid to the  applicable  taxing  authority.  Premium  taxes  shall be  allocated
between  Buyer and Seller  pursuant to the terms of the  Assumption  Reinsurance
Agreement, except that premium taxes relating to Seller's contracts with OPM and
HCFA shall be allocated as provided in this Agreement.

         1.3.4.   Transfer Taxes; Recording Fees.

     The Buyer and Seller shall share equally any and all sales,  use,  transfer

1.4.     Purchase Price.

         1.4.1.   Purchase Price.

     The  consideration  for the transfer of the Assets from Seller and Seller's
Affiliates to Buyer shall be One Hundred Twenty Seven Million Two Hundred Twenty
Four  Thousand  Three  Hundred  Nine Dollars  ($127,224,309.00),  as adjusted as
provided in this  Section  1.4  ("Purchase  Price").  Ninety  Seven  Million Two
Hundred Twenty Four Thousand Three Hundred Nine Dollars  ($97,224,309.00) of the
Purchase  Price  shall be paid by Buyer to Seller by Federal  Reserve  Bank wire
transfer of good funds at Closing,  as adjusted as provided in this Section 1.4.
The remaining  Thirty  Million  Dollars  ($30,000,000.00)  of the Purchase Price
shall be paid in accordance  with the earn-outs set forth in Sections  1.4.4 and
1.4.5 below. The parties acknowledge that the amount of Two Hundred Seventy Five
Thousand Six Hundred  Ninety One Dollars  ($275,691.00)  is the  purchase  price
associated  with the Insurance  Assumption  Reinsurance  Agreement and that such
amount  is not  included  in the  term  Purchase  Price  for  purposes  of  this
Agreement.

         1.4.2.   Certain Balance Sheet Adjustments to Purchase Price.

     (a) The Opening  Balance  Sheet (and related  worksheets,  working  papers,
notes  and  schedules  thereto,  if  applicable),  attached  hereto  as  Exhibit
1.4.2(a),  sets  forth,  at March 31,  1998,  the book  value of the  assets and
liabilities  of Seller.  Except as expressly  provided by the rules set forth in
Exhibit 1.4.2(a)-1 ("Rules"),  the Opening Balance Sheet (i) fairly presents the
financial  position of Seller at March 31,  1998,  in  conformity  with US GAAP,
applied on a consistent basis, and (ii) reflects all write-offs or

                                                         7

<PAGE>



     revaluations of assets (except as specified therein). The reserves recorded
in the Opening  Balance Sheet were  prepared in accordance  with US GAAP and are
consistent  with the  statutory  or other  accounting  practices  prescribed  or
permitted by the insurance  regulatory  authorities of the State of Texas and of
all the jurisdictions in which Seller is licensed to transact insurance business
and make good and sufficient provision for all insurance  obligations of Seller.
If there is a  conflict  between  US GAAP and the  Rules,  the Rules  shall take
precedence.

     (b) Not less than five  business  days prior to the  Closing  Date,  Seller
shall deliver to Buyer a balance sheet  ("Interim  Balance  Sheet") for the most
recent month end prior to the Closing Date, prepared in accordance with US GAAP,
the Rules, and other standards applicable to the Closing Balance Sheet. Not more
than 15 days after the Closing  Date,  Seller shall deliver to Buyer the closing
balance sheet ("Closing  Balance Sheet") pursuant to which the book value of the
current  assets  included  in the  Assets  less  the book  value of the  current
liabilities included in the Assumed Liabilities ("Closing Working Capital") will
be zero at the Closing Date.  The Closing  Balance Sheet will (i) fairly present
the financial  position of Seller as at the Closing Date, in conformity  with US
GAAP,  applied on a consistent  basis,  and (ii) will reflect all  write-offs or
revaluation  of assets.  Seller will provide a list of all write-offs or partial
write-downs of assets from the Opening Balance Sheet in excess of $5,000.00. The
reserves  recorded in the Closing  Balance  Sheet will be prepared in accordance
with US GAAP  and will be  consistent  with the  statutory  or other  accounting
practices prescribed or permitted by the insurance regulatory authorities of the
State of Texas  and of all the  jurisdictions  in which  Seller is  licensed  to
transact  insurance  business and make good and  sufficient  provisions  for all
insurance  obligations of Seller. If there is a conflict between US GAAP and the
Rules, the Rules shall take precedence.  If the book value of the current assets
included in the Assets of Seller less the book value of the current  liabilities
included in the Assumed  Liabilities of Seller set forth on the Interim  Balance
Sheet is less than zero,  the Purchase Price payable at Closing shall be reduced
by the amount of such deficit,  without  prejudice to either party to assert any
adjustments  pursuant to this  Section  1.4.2.  If the book value of the current
assets  included  in the  Assets of Seller  less the book  value of the  current
liabilities  included  in the  Assumed  Liabilities  of Seller  set forth on the
Interim  Balance Sheet is more than zero,  the Purchase Price payable at Closing
shall be  increased by the amount of such  excess,  without  prejudice to either
party to assert any adjustments pursuant to this Section 1.4.2. The parties may,
by mutual  agreement,  arrange for Seller to retain and  discharge  on or before
Closing certain  liabilities set forth on the Closing Balance Sheet in the place
of all or part of any  necessary  adjustment  to the Purchase  Price  payable at
Closing.

     (c) Seller shall  promptly pay to Buyer the amount of any payable of Seller
booked to the Closing Balance Sheet under Rule 9 on Exhibit 1.4.2(a)-1,

                                                         8

     and Buyer shall  promptly  pay to Seller the amount of any payable of Buyer
booked to the  Closing  Balance  Sheet  under Rule 9 on Exhibit  1.4.2(a)-1.  In
addition, if at any time, either party determines that the Closing Balance Sheet
is not in conformity with the standards set forth in Section  1.4.2(b),  and the
Closing  Working  Capital was not zero, it shall promptly notify the other party
of such discrepancy in writing, setting forth in detail the basis for its belief
that a discrepancy exists, and the Purchase Price shall be adjusted as set forth
below;  provided  however,  (i) no adjustments shall be made with respect to any
event that occurs subsequent to December 31, 1999; and (ii) no adjustments shall
be made  with  respect  to any  proposed  adjustment  not  asserted  in  writing
containing a reasonable description of the proposed adjustment sent on or before
March 31, 2000.

     (d) If, as a result of an  adjustment  to the Closing  Balance  Sheet,  the
Closing Working Capital is less than zero, Seller shall promptly pay in full the
amount by which it is less than zero to Buyer.  If, as a result of an adjustment
to the Closing  Balance Sheet,  the Closing  Working  Capital is more than zero,
Buyer shall promptly pay the amount by which it is more than zero to Seller. All
amounts due hereunder shall be paid within 30 days of receipt of notice from the
other party that an amount is due and owing unless,  within such 30-day  period,
the matter has been made the subject of a dispute  resolution  proceeding as set
forth in Section 1.4.2(e).

     (e) If one party  ("Notifying  Party")  has  given  the  other  ("Receiving
Party")  written  notice that it believes an adjustment  to the Closing  Balance
Sheet or the Closing  Working  Capital is  appropriate,  and the Receiving Party
does not agree that an adjustment is appropriate,  or disputes the amount of the
adjustment,  then the Receiving Party shall give the Notifying Party notice that
it is  submitting  the matter to the dispute  resolution  procedure set forth in
this  Section  1.4.2(e).  In that event,  the parties  shall seek,  for a 30-day
period  following the notice from the Receiving Party to the Notifying Party, to
come to an  agreement  on the  amount,  if any, of the  appropriate  adjustment.
During  that  30-day  period,  (i) each  party  shall  share  with the other the
information  in its  possession  that causes it to believe that an adjustment is
required,  and (ii)  representatives  of each party who are authorized to settle
the dispute  shall meet to discuss the  resolution  thereof.  If the parties are
unable to reach  resolution of the dispute within the 30-day period,  they shall
promptly  submit  the  matter  to an  independent  "Big  Six"  accounting  firm,
acceptable to both parties, and the determination of the independent  accounting
firm as to the amount,  if any, of the  adjustment,  shall be conclusive and not
subject to arbitration  under this  Agreement.  Each party shall cooperate fully
with the  independent  accounting firm and provide to it such documents and work
papers as it may request in making its determination. The cost of the submission
of the adjustment to the independent accounting firm shall be borne by the party
whose  position  is  most  at  variance  with  the  final  determination  of the
independent accounting

     firm. All amounts due from one party to the other shall be promptly paid in
full upon the resolution of the matter by the independent accounting firm.

     (f) Either  party may,  through  its own  employees  or through  designated
representatives, review and audit the proposed adjustments asserted by the other
party.  Each party  shall fully  cooperate  with such review and audit and shall
share with the other  party and its  designated  representatives,  such  working
papers and accounting records as they may reasonably  request.  Each party shall
use  commercially  reasonable  efforts to conduct its review and audit in such a
manner as to not  unreasonably  interfere with the other party's  conduct of its
business.

     (g) The entries on the Opening  Balance Sheet and the Closing Balance Sheet
that are the subject of the Post Closing  Reconciliation  and Report Procedures,
as defined  and set forth in the  Reinsurance  Agreements,  shall be adjusted in
accordance with the terms of the Reinsurance Agreements.  Such adjustments under
the  Assumption  Reinsurance  Agreement  shall  not  be  duplicated  under  this
Agreement  and  shall be  netted  against  any  adjustments  or  indemnification
payments hereunder made with respect to the same event or circumstance.

         1.4.3.   Collection of Receivables.

     (a) Seller may, from time to time, review the collection efforts being made
by Buyer with  respect to accounts  receivable  included on the Closing  Balance
Sheet  which are aged at least 90 days.  If at any  time,  or from time to time,
Seller wishes to assume responsibility for collection of all or any part of such
receivables  listed on the Closing  Balance Sheet,  Seller shall notify Buyer in
writing  that it  wishes to do so,  and  Buyer  shall  provide  Seller  with all
information necessary or appropriate to enable Seller to collect the amounts due
on the accounts so designated.  Buyer shall not have any  responsibility to take
any action  with  respect to  accounts  receivable  following  the  transfer  of
responsibility for their collection to Seller.

     (b) Any amounts  collected  by Seller on national or  multi-state  accounts
with respect to Members under Subscription  Agreements  transferred  pursuant to
this Agreement shall be paid to Buyer within 15 business days of receipt.

         1.4.4.   Purchase Price Earn-Out for Growth in Certain Member Accounts.

     Buyer shall pay to Seller,  in accordance with this Section 1.4.4, up to an
additional  Twenty  Seven  Million  Dollars  ($27,000,000.00)  on account of (i)
post-Closing  increases in the membership count of employer groups identified by
Seller prior to Closing as national accounts ("Old National  Accounts") over the
membership level of such accounts at the Closing,  and (ii) new accounts written
by Buyer or Buyer's  Affiliates in their Dallas,  Houston,  Las Vegas,  and Reno
service  areas  after the  Closing  ("New  Accounts")  which  Seller or Seller's
Affiliates has been primarily responsible for obtaining on Buyer's behalf.

                                                        10

<PAGE>



     The names and membership levels of the Old National  Accounts  ("Membership
Base") at March 31, 1998 is set forth in Schedule 1.4.4.  This Schedule shall be
replaced  by Seller  within 60 days  after  Closing  to  reflect  additions  and
deletions to names and  membership  levels  effective the Closing Date.  The Old
National  Accounts  and  the  New  Accounts  are,  collectively,  the  "Earn-Out
Accounts."

     (a) If the number of Members in the  Earn-Out  Accounts at the first annual
anniversary of the Closing Date is equal to or in excess of the First Membership
Milestone  percentages of the number of Members in the Earn- Out Accounts at the
Closing Date,  Buyer shall pay Seller the amount  opposite the  percentage.  The
amount paid to Seller shall be prorated between the First  Membership  Milestone
percentages.  First  Membership  Milestones  (1st  Anniversary  Compared  to the
Closing  Date)  Earn-Out 107% $9 Million 100% $6.75 Million 90% $4.5 Million 80%

     (b) If the number of Members in the Earn-Out  Accounts at the second annual
anniversary  of the  Closing  is equal to or in excess of the  following  Second
Membership  Milestone  percentages  of the  number of  Members  in the Earn- Out
Accounts at the Closing Date plus 7%, Buyer shall pay Seller the amount opposite
such  percentage,  less any amount  already  paid to Seller at the first  annual
anniversary of the Closing.  The amount paid to Seller shall be prorated between
the Second Membership Milestone  percentages.  If the amount owed Seller is less
than the amount paid Seller at the first  anniversary,  Seller  shall  return to
Buyer the difference.  Second Membership Milestones (2nd Anniversary Compared to
the Closing  Date)  Earn-Out  114% $18 Million 107% $13.5 Million 96% $9 Million
86% $4.5 Million Less than 86% - 0 -

     (c) If the number of Members in the  Earn-Out  Accounts at the third annual
anniversary of the Closing Date is equal to or in excess of the Third Membership
Milestone  percentages of the number of Members in the Earn- Out Accounts at the
Closing  Date  plus 14%,  Buyer  shall  pay  Seller  the  amount  opposite  such
percentage,  less any  amount  already  paid to Seller  at the first and  second
annual anniversaries of the Closing. The amount paid to Seller shall be prorated
between the Third Membership Milestone percentages. If the amount owed Seller is
less than the amount paid Seller at the first and second  anniversaries  (net of
any payments from Seller to

     Buyer at the first and second  anniversaries)  Seller shall return to Buyer
the difference.  Third Membership  Milestones (3rd  Anniversary  Compared to the
Closing Date)  Earn-Out 122% $27 Million 114% $20.25  Million 103% $13.5 Million
91% $6.75 Million Less than 91% - 0 -

     (d) Buyer agrees to make available to the Earn-Out Accounts benefit designs
and rates consistent with prudent business practices. Such benefit designs shall
also be materially  consistent with the Old National Accounts existing as of the
Closing Date.

     (e) Calculations and audits thereof shall be undertaken by Seller and Buyer
within 90 days of each annual anniversary, with any payment owed by one party to
the other paid  within  120 days of each  annual  anniversary.  Seller and Buyer
shall each have the right to inspect  and  photocopy  those books and records of
the other  necessary  to verify any amounts that may be owed by one party to the
other under this Section.

         1.4.5.   Purchase Price Earn-Out for NCQA Accreditation.

     Buyer shall pay Seller  Three  Million  Dollars  ($3,000,000.00)  if Seller
achieves for the HMO Business a full one-year or better non-provisional National
Committee on Quality Assurance ("NCQA")  accreditation  certificate for the NCQA
survey currently scheduled on or about July of 1998. Buyer shall pay Seller such
amount within five business days of receipt of proof of such  certification from
NCQA.  Buyer  agrees  not to take any  action  other  than  entering  into  this
Agreement which might delay the July, 1998 NCQA site visit.

     1.4.6. Purchase Price Decrease for Decrease in Certain Member Accounts.

     If at  Closing,  the total  number of Seller's  Commercial  HMO Members (as
herein defined) plus Medicare risk HMO Members is less than 114,000, Buyer shall
be entitled to reduce the  Purchase  Price by an amount  equal to Seven  Hundred
Forty Five Dollars  ($745.00)  multiplied  by the  difference  between the total
number of Seller's  Commercial  HMO Members plus  Medicare  risk HMO Members and
114,000;  provided,  however,  that if Buyer declines to accept the  assignment,
reinsurance,  novation or other  transfer of certain  Commercial  HMO Members or
Medicare risk HMO Members from Seller to Buyer,  including,  without limitation,
Group 3000,  such  Commercial HMO Members or Medicare risk HMO Members shall not
be  included  in this  difference.  Calculation  and audits of  Seller's  actual
Commercial  HMO Members plus  Medicare  risk HMO Members as of Closing  shall be
undertaken by Seller and Buyer within 90 days of the Closing.  Such  calculation
and audit shall be completed within 180 days following the Closing. For purposes
of such calculation, an individual shall not be considered a Commercial HMO

                                                        12

     or Medicare risk HMO Member if there is an account  receivable for premiums
associated  with such  individual in excess of 120 days.  Buyer shall apply such
reduction  first to offset any amounts  owed by Buyer to Seller  under  Sections
1.4.4 and  1.4.5.  If such  offset  proves  to be  inadequate,  Seller  shall be
required to refund to Buyer the remaining  amount owed within 15 business  days.
The term  "Commercial HMO Members" shall mean those persons enrolled with Seller
for HMO and  point-of-service  benefits  under group and  individual  Subscriber
Agreements, including, without limitation, through the Old National Accounts and
OPM and other  governmental  groups,  but excluding any Medicare cost enrollees,
fee-for-service patients and preferred provider organization beneficiaries.

     Note 1: POS revenue  shall be calculated  as follows:  account  number 4020
less account number 4920; gross up net balance by 40%.

Note 2: Account number 4950, other regions' members dues is not included in this
calculation.

     If, for the first  calendar  quarter of 1998,  the actual Premium Yield for
all Commercial HMO Members is not $123.12,  (i) Seller shall (up to a maximum of
Three Million Five Hundred Thousand Dollars ($3,500,000.00)) pay to Buyer if the
Premium  Yield is lower than  $123.12,  or (ii) Buyer  shall (up to a maximum of
Three Million Five Hundred  Thousand Dollars  ($3,500,000.00))  pay to Seller if
the Premium  Yield is higher than  $123.12,  the  difference  between the actual
Premium Yield and $123.12  multiplied  by the actual  number of  Commercial  HMO
Member months for the same quarter times four.  "Premium Yield" shall mean gross
billed  premiums  (including  100% of premium  revenue  due Seller and  Seller's
Affiliates  for  point-of-service  Members,  without  offset  for the  indemnity
component of the point-of-service plan), less cancellations,  returned premiums,
and bad debt but shall not include deductions for commissions,  premium taxes or
Texas Health Insurance Risk Pool Assessments.  The calculation  required by this
Section  shall be made by Seller and Buyer  within 60 days of  Closing  with any
payment owed due within 90 days of Closing.  Such calculation shall be performed
using the identical  methodology as the calculations set forth above, subject to
such  methodology  being consistent with Seller's past practice as it relates to
payment of commissions.

         1.4.8.   Allocation.

     Prior to the Closing Date,  the parties shall agree to an allocation of the
Purchase Price among the Assets in accordance with the Code; provided,  however,
the parties' agreement on such allocation shall not be a condition to Closing.

Agreement shall take place on the date ("Closing Date") which,  unless otherwise
agreed by Buyer and Seller,  shall be effective the last day of the month during
the calendar month after all conditions  precedent of Buyer and Seller which are
set forth in this  Agreement  have been fully  satisfied  or have been waived in
writing;  provided,  however, that notwithstanding the actual time of the day on

("Closing")  shall be deemed to be effective as of and to occur, and the risk of

covenants and agreements  have not been complied with in all material  respects,
Seller shall provide a list  describing  in reasonable  detail the extent of the

Notwithstanding  the above, if such  representations and warranties are not true

         1.6.3.   Third Party Consents.

     (a) To the extent that Seller's rights under any contracts  (other than the
Subscriber  Agreements) relating to the Business may not be assigned without the
consent of a third party,  which consent has not been obtained prior to Closing,
this  Agreement  shall not  constitute  an  agreement  to assign  the same if an
attempted  assignment would constitute a breach thereof or be unlawful.  Seller,
at its expense, shall use its commercially reasonable

                                                        18

<PAGE>



     efforts to obtain any such required  consents as promptly as possible after
Closing.  If any such consents are not obtained or if any  attempted  assignment
would be  ineffective  or would impair Buyer's rights so that Buyer would not in
effect  acquire the benefit of all such rights,  Seller,  to the maximum  extent
permitted  by law and by the terms of the  applicable  contract(s),  at Seller's
expense, shall act for six months after the Closing as Buyer's agent in order to
obtain for Buyer the benefits  thereunder,  and shall cooperate,  to the maximum
extent  permitted by law and by the terms of the  applicable  contract(s),  with
Buyer in any other  reasonable  arrangement  designed to provide the benefits of
such  contracts  to  Buyer.  Alternatively,   at  Seller's  option,  Seller  may
recharacterize  any contract of Seller for which the required consent of a third
party could not be obtained at Closing or within six months  after  Closing Date
as an  Excluded  Asset (and not an Asset to be  transferred  to Buyer),  and all
rights and obligations relating to such contract shall remain with Seller.

     (b)  Notwithstanding  Section  1.6.3(a)  above,  should Seller be unable to
obtain the third party  consents  required to assign the hospital  contract with
certain  Columbia  hospitals,  dated  January  1, 1995,  as  amended  ("Columbia
Hospital  Contract"),  Seller shall attempt to  substitute an adequate  hospital
network for the  existing  service  area of the HMO  Business.  Irrespective  of
whether Seller or Buyer provides such substitute hospital network,  Seller shall
pay to Buyer 75% of the excess  (if any) of the  amount  that Buyer must pay for
hospital services with such substitute hospital delivery network over the amount
which Buyer would have enjoyed as an assignee of Seller pursuant to the Columbia
Hospital  Contract,  for the period from the Closing Date  through  December 31,
1999.  The amount due  hereunder  shall be  determined by repricing the services
actually used during the period in question as if they had been  provided  under
the Columbia Hospital Contract.

     (c)  All  third  party  consent  issues  with  respect  to  the  Subscriber
Agreements shall be resolved pursuant to the terms of the Assumption Reinsurance
Agreement.

2.       REPRESENTATIONS AND WARRANTIES OF SELLER.

     The  parties  acknowledge  that there are  additional  representations  and
warranties  relating to the  Subscriber  Agreements  set forth in the Assumption
Reinsurance Agreement.  "Material Adverse Effect" means, with respect to Seller,
an  adverse  effect  on  the  Assets  or the  Assumed  Liabilities  which  would
materially  impair the ability of Buyer to operate the Business in substantially
the manner it has been heretofore conducted.

2.1.     Representations and Warranties of Seller.

     As of the  Execution  Date,  Seller  represents  and  warrants  to Buyer as
follows:

         2.1.1.   Organization and Good Standing.

     Seller is a non-profit corporation duly organized,  validly existing and in
good standing under the laws of the  jurisdiction if its  organization,  has all
requisite  corporate power and corporate authority to own, lease and operate its
properties and to carry on the Business,  as it is now being  conducted,  and is
duly  qualified and in good standing to do business  under the corporate laws of
each  jurisdiction  in which the  nature of the  Business  or the  ownership  or
leasing of its properties makes such qualification  necessary,  except where the
failure to be so qualified would not have a Material Adverse Effect.

         2.1.2.   Seller's Authority and No Breach.

     Seller has all requisite  corporate power and corporate  authority to enter
into this Agreement and to consummate the transactions  contemplated hereby. The
execution  and  delivery  of  this  Agreement  and  the   consummation   of  the
transactions  contemplated  hereby have been duly  authorized  by all  necessary
corporate action on the part of Seller and, as necessary,  Seller's  Affiliates.
This Agreement constitutes a valid and binding obligation of Seller, enforceable
against  Seller in all material  respects in accordance  with its terms,  except
insofar as enforcement may be limited by insolvency or similar laws affected the
enforcement of creditors' rights in general, and except as enforceability may be
limited  by  general   principles   of  equity   (regardless   of  whether  such
enforceability is considered in a proceeding in equity or at law).

         2.1.3.   No Violations.

     Except  for  consents  of  third  parties  required  under  contracts,  the
execution and delivery of this Agreement does not, and the  consummation  of the
transactions  contemplated hereby will not, (i) conflict with, or result in, any
material  violation of, or default (with or without  notice or lapse of time, or
both)  under,  or  give  rise  to  a  right  of  termination,   cancellation  or
acceleration of any material obligation or the loss of a material benefit under,
or the creation of a material lien, material security interest or other material
encumbrance  with  respect  to,  any  material  portion of the Assets or Assumed
Liabilities  (any  such  conflict,  violation,  default,  right of  termination,
cancellation or acceleration, loss or creation, a "Violation"),  pursuant to any
provision of the Articles of Incorporation or By- laws of Seller, (ii) result in
any Violation of any material  agreement which constitutes part of the Assets or
Assumed  Liabilities,  (iii) result in any Violation of any  judgment,  order or
decree  entered  with  respect to Seller or to which the  Assets or the  Assumed
Liabilities are subject, or, (iv) to Seller's knowledge, result in any Violation
of any statute,  law, ordinance,  rule or regulation applicable to the Assets or
the Assumed Liabilities,  except in each of clauses (i) through (iv), where such
Violations,  individually or in the aggregate, would not have a Material Adverse
Effect.

         2.1.4.   No Consents.

                                                        20

<PAGE>




     No  consent,   approval,   order  or  authorization  of,  or  registration,
declaration  or filing with, any court,  administrative  agency or commission or
other   governmental   authority   or   instrumentality,   domestic  or  foreign
("Governmental  Entity"), is required by or with respect to Seller in connection
with the execution and delivery of this Agreement by Seller, or the consummation
by Seller of the transactions  contemplated hereby, except for (i) the filing of
a premerger notification report by Seller under the Hart-Scott-Rodino  Antitrust
Improvements  Act of 1976,  as  amended  ("HSR  Act"),  and (ii)  such  filings,
authorizations,  orders and  approvals as may be required by federal,  state and
local  Governmental  Entities,  including  those  in  connection  with  Seller's
insurance business.

         2.1.5.   Seller's Financial Statements.

     Seller has delivered (or if not yet available as of the Execution Date will
promptly  deliver when available  prior to the Closing Date) to Buyer,  complete
and correct  copies of (i) the audited  balance  sheets of Seller as at December
31, 1995, 1996 and 1997, and those related audited statements of income and cash
flows,  for the fiscal years ended on those dates,  together  with all footnotes
and (ii) the unaudited  interim balance sheet and statement of income for Seller
for the fiscal period ended on March 31, 1998 and  subsequent  quarters prior to
Closing.  All of such  financial  statements  fairly  present,  in all  material
respects,  as at and for the periods then ended, as the case may be (subject, in
the case of the  unaudited  balance  sheet  and  income  statement,  to  normal,
recurring adjustments and the absence of footnotes),  the financial position and
results of operations of Seller in conformity with generally accepted accounting
principles  prevailing  in the United  States ("US GAAP") or  statutory or other
accounting  practices  prescribed  or  permitted  by  the  insurance  regulatory
authorities  in the State of Texas,  in each case applied on a basis  consistent
throughout the reported periods. Such financial statements (i) do not contain or
when delivered will not contain,  as the case may be, any item of  extraordinary
or  non-recurring  income or expense  (except as  specified  therein);  and (ii)
reflects all write-offs or necessary  revaluation of assets (except as specified
therein).  The  reserves  recorded  in the  accounting  records  of  Seller  for
insurance  or HMO policy  benefits,  losses,  claims and  expenses and any other
reserves  were prepared in  accordance  with the  statutory or other  accounting
practices prescribed or permitted by the insurance regulatory authorities of the
State  of Texas  and  make  good and  sufficient  provisions  for all  insurance
obligations of Seller.

         2.1.6.   Litigation.

     To Seller's knowledge,  except as set forth on Schedule 2.1.6, there are no
actions, suits, proceedings,  of any kind pending, or investigations of any kind
now pending or  threatened in writing and  involving  Seller,  the Assets or the
Assumed Liabilities, which may have a Material Adverse Effect.

                                                        21

<PAGE>




         2.1.7.   Compliance With Applicable Laws.

     Except as set forth on  Schedule  2.1.7,  and  except  to the  extent  that
non-compliance  would not have a Material Adverse Effect, the Business of Seller
is being conducted in compliance with all applicable  laws,  rules,  ordinances,
regulations,  licenses, or judgments, or orders, rules,  regulations,  licenses,
judgments, or decrees of Governmental Entities. Seller holds all certificates of
authority, permits, licenses, consents, certificates,  orders and approvals from
all Governmental Entities (collectively, "Seller's Permits") which are necessary
to own, lease and operate the Assets in the manner heretofore conducted,  except
to the extent  that  failure to hold same does not result in a Material  Adverse
Effect.  Seller has filed all material  statements  and reports  with  insurance
regulatory authorities required by the law, regulations,  licensing requirements
and orders  administered or issued by such regulatory  authorities.  To Seller's
knowledge,  no event has occurred with respect to any of such  Seller's  Permits
which would cause revocation,  termination or suspension of any of such Seller's
Permits if such revocation,  termination,  suspension or impairment would have a
Material Adverse Effect. Seller has not, and, to Seller's knowledge, none of its
executive  officers,  directors or employees (in their respective  capacities as
such),  has engaged in any activity  constituting  fraud or abuse under the laws
relating to health care or insurance.

         2.1.8.   Labor and Employment Matters.

     Except as set forth on Schedule 2.1.8,  (i) Seller has no employees who are
represented by a labor union or organization, no labor union or organization has
been  certified or recognized as a  representative  of any such  employees,  and
Seller is not a party to and does not have any obligation under any collectively
bargaining  agreement  or other  contract or  agreement  with any labor union or
organization;  (ii) there are no pending or, to Seller's knowledge,  threatened,
representation campaigns, elections or proceedings or questions concerning union
representation involving any employees of Seller; and (iii) Seller does not have
any knowledge of any  activities or efforts of any labor union or  organizations
(or representatives  thereof) to organize any of its employees,  any demands for
recognition for collective bargaining, any strikes, slowdowns, work stoppages or
lock-outs of any kind, or threats  thereof,  by or with respect to any employees
of Seller, and no such activities,  efforts, demands,  strikes,  slowdowns, work
stoppages  or  lock-outs  occurred  during a  three-year  period  preceding  the
Execution Date.

         2.1.9.   Absence of Certain Changes.

     Since March 31, 1998,  except (i) as set forth on Schedule 2.1.9,  (ii) for
the execution and delivery of this Agreement and changes in Seller's  properties
or Business  attributable  to the  transactions  contemplated or necessitated by
this  Agreement  and the  Related  Agreements  (as herein  defined)  (including,
without  limitation,   the  spin-off  of  Consolidated  Service  Center  assets,
employees  and  operations  on or before  Closing),  and (iii) as  disclosed  in
Seller's  financial  statements  as  previously  delivered or to be delivered to
Seller:


                                                        22

<PAGE>



     (a) Seller has not made any material  change in its  accounting  methods or
practices with respect to its condition,  operations,  the Business, the Assets,
or the Assumed Liabilities;

     (b)  Seller  has  not  entered  into or  materially  amended  any  contract
requiring  payment by Seller,  on an annualized  basis,  of more than  $250,000,
which contract is not terminable without cause on 90 days notice or less;

     (c) Seller has not permitted any lien, charge or encumbrance on the Assets,
to the extent such lien,  charge or  encumbrance  would have a Material  Adverse
Effect;

     (d) Seller has not increased,  or agreed to increase,  the  compensation of
any of the Terminated  Employees,  over the rate being paid to them on March 31,
1998, other than normal merit and cost-of-living increases pursuant to customary
arrangements consistently followed and any special retention bonuses relating to
the winding down of Seller's Business;

     (e) Except for transactions that,  individually or in the aggregate,  would
not have a Material  Adverse Effect,  Seller has (i) conducted its Business in a
commercially  prudent manner, as a going concern and in the ordinary course, and
consistent  with  such  operation,   complied  in  all  material  respects  with
applicable  legal and  contractual  obligations,  consistent with past practice;
(ii) used commercially  reasonable  efforts,  consistent with past practice,  to
preserve  the  goodwill  of its  Members and its  employees,  including  without
limitation,  issuing  rate  quotes  and  taking  such  other  action  as  may be
necessary;  and (iii) not intentionally taken any action outside of the ordinary
course of  business  which would tend to cause  employer  groups,  suppliers  or
Members to cease their respective affiliations with Seller.

         2.1.10.           Material Contracts.

     Each  material  contract  constituting  part of the  Assets or the  Assumed
Liabilities  is in full force and effect and is valid and  enforceable by Seller
in accordance  with its terms,  except insofar as enforcement  may be limited by
bankruptcy,  insolvency or similar laws affecting the  enforcement of creditors'
rights in  general,  and  except as  enforceability  may be  limited  by general
principles of equity (regardless of whether such enforceability is considered in
a  proceeding  in equity or at law).  Seller is not in  material  default in the
observance or the  performance  of any term or obligation to be performed by its
under any such  Agreement to the extent that such default would cause a Material
Adverse effect. To Seller's knowledge, no other person is in material default in
the  observance or the  performance of any term or obligation to be performed by
it under any such  contract  to the  extent  that such a default  would  cause a
Material  Adverse  Effect.  There is  currently no  outstanding  bid or contract
proposal by Seller  which,  if accepted or entered  into,  might  reasonably  be
expected to result in a Material  Adverse Effect.  Seller has provided,  or will
provide before 60 days after the Execution  Date,  originals or true and correct
copies of

                                                        23

<PAGE>



     all  contracts  constituting  part of the  Assets  or  Assumed  Liabilities
requiring  payment by Seller,  on an annualized basis, of more than $250,000 and
which contracts are not terminable on 90 days notice or less.

         2.1.11.           Title to and Condition of Assets.

     Except as set forth on Schedule  2.1.11 or reflected on the Opening Balance
Sheet,  Seller has good title to the Assets,  whether  owned or leased,  in each
case subject to no mortgage,  pledge,  conditional sales contract lien, security
interest,  right  of  possession  in favor of any  third  party,  claim or other
encumbrance (collectively, "Liens"), and except with respect to leased property,
the provisions of the applicable  leases. No representation or warranty is being
made with  respect to the  physical  condition  of the  Assets,  and Buyer shall
receive the Assets in their "AS-IS" condition.

         2.1.12.           Patents, Copyrights, Service Marks and Trademarks.

     Seller is not transferring to Buyer any patents, copyrights, service marks,
trademarks, or other intellectual property other than its rights, as a licensee,
to use certain software, as described elsewhere in this Agreement.

         2.1.13.           No Broker or Finders.

     No  broker or finder is  involved  on behalf of Seller or an  Affiliate  of
Seller in connection  with the sale of the Assets,  nor may any broker or finder
involved on behalf of Seller claim any  commission on account of the sale of the
Assets. The parties  acknowledge that Wasserstein Perella & Co. has been engaged
by Seller as a financial advisor to Seller, and the fees of Wasserstein  Perella
& Co. shall be paid for by Seller.

         2.1.14.           Tax Returns and Tax Liabilities.

     To Seller's  knowledge,  Seller has made and is current with respect to all
reports,  returns and other  filings  (collectively,  "Returns")  required to be
furnished from time to time to all federal,  state,  local or other governmental
tax or fiscal authorities (including,  without limitation, all real and personal
property, informational, franchise and withholding taxes and other Returns); all
such Returns so furnished  were correct in all material  respects;  and based on
the  applicable  measure of Seller's  operations  or Assets during the period in
question;  each such Return  correctly stated and reported the amount due in all
material  respects;  true and correct copies of all such Returns are included in
Seller's files; and all amounts reflected as due and payable on the Returns have
been paid.

         2.1.15.           No Untrue Representation or Warranty.

     To  Seller's  knowledge,  no  representation  or warranty by Seller in this
Agreement,  nor any  statement  or  certificate  furnished or to be furnished to
Buyer pursuant hereto or in connection with the transactions contemplated hereby
contains or will contain any untrue statement of a material fact.

2.2.     Representations and Warranties True and Correct at Closing; Breaches.

     Seller  shall  execute  and  deliver  to Buyer a  certificate  signed by an
authorized  representative of Seller, dated as of the Closing Date, stating that
each of the  representations  and  warranties of Seller made herein are true and
correct in all  respects as of the Closing  Date,  or  describing  the manner in

duly  qualified and in good standing to do business  under the corporate laws of
each  jurisdiction  in which the  nature of its  business  or the  ownership  or
leasing of its properties makes such qualification  necessary,  except where the
failure to be so qualified would not have a Material Adverse Effect.

         3.1.2.   Buyer's Authority and No Breach.

     Buyer has all requisite  corporate  power and corporate  authority to enter
into this Agreement and to consummate the transactions  contemplated hereby. The

against  Buyer in all material  respects in  accordance  with its terms,  except
insofar as enforcement may be limited by insolvency or similar laws affected the
enforcement of creditors' rights in general, and except as enforceability may be
limited  by  general   principles   of  equity   (regardless   of  whether  such
enforceability is considered in a proceeding in equity or at law).

Closing Date, then Seller shall be entitled to  indemnification  for any and all
losses as provided in Section 11. The  consummation  of the  transactions  under

indemnification  for a breach of a  representation  or warranty  provided for in
this Section.

4.       SURVIVAL OF REPRESENTATIONS AND WARRANTIES.

     The  representations  and  warranties  of Buyer  and  Seller  contained  in

an annualized  basis, of more than $250,000.00  which contract is not terminable

Dallas-Fort  Worth,  Texas,  or any other area  within the State of Texas  where
Seller or its Affiliates conducted business as of the Closing Date, or (ii) make
any federal,  state or local regulatory filing with the purpose of being granted

provider  or  hospital  business,  including,  without  limitation,  any  health
maintenance organization, health care preferred provider organization,  multiple

and permanent  injunctive relief without the necessity of proving actual damage.

otherwise  contravene the  provisions of applicable  law, then the parties agree
that such  provisions  shall be reformed  to set forth the  maximum  permissible
limitations or provisions allowable by law.

Seller of its obligations  under Seller's  existing  contracts with HCFA or OPM,

regulators, service providers, employees, vendors, shareholders,  suppliers, and
third party  contractors  required by law or in the ordinary course of business.
In no event shall  either  party cause any oral or written  communication  to be

not a condition to Buyer's  obligation  to close the  transactions  contemplated
hereby.

10.3.    Office of Personnel Management.

     (a) Buyer and Seller  acknowledge and agree that Seller's contract with OPM
is not assignable without the written consent or approval of OPM, and assignment
of such contract  shall require the  preparation  and execution of a novation or
other agreement ("OPM Novation  Agreement") by and among Buyer,  Seller and OPM.

within a  reasonable  period of time after the  Closing.  Seller and Buyer shall
cooperate  reasonably  to effect the  transfer of the  contingency  reserve fund

through 11.4, Seller hereby agrees to indemnify and hold harmless Buyer from and
against any and all losses,  damages,  costs and expenses (including  reasonable
attorneys'  fees)  arising  out of or  sustained  as a  result  of any  negative
adjustment made by the government under Seller's contract with OPM (such losses,
damages,  costs and expenses are hereinafter referred to as the "Indemnification
Liability") with respect to contract periods prior to contract year 1999.

     (c) With respect to contract year 1999, Seller's indemnification obligation
shall be limited to 75% of any Indemnification  Liability up to a maximum amount
of $2,000,000. Provided, however, that Seller shall have no liability under this
Section to the extent that any rate adjustment required by OPM is (i) the result
of rates  quoted by Buyer  which are lower than the current  rates for  existing
groups of Seller as long as standard rating  methodology was employed for rating
similarly sized groups;  and/or (ii) the result of rates quoted by Buyer for new
groups.  Seller  further agrees that the rate charged OPM for contract year 1999
shall not be less than the rate charged OPM for 1998.

     (d)  The  CRF is and  will  be  properly  funded  in  accordance  with  OPM
regulations  and  applicable  laws.  Only those  amounts  which OPM deems are in
excess of what is required and OPM allows to be removed by a contractor under

                                                        34

     applicable laws and regulations as a lump sum payment will be considered an
excess.  Buyer shall,  upon  receipt from OPM of any lump sum payment  resulting
from any positive  adjustment made by OPM for contract periods prior to contract
year 1999,  remit such amount to Seller.  For  contract  year 1999,  Buyer shall
retain 25% of any lump sum payment  resulting from any positive  adjustment made
by the OPM for that year and the balance  shall be remitted to Seller.  Payments
to be made hereunder shall be by wire transfer within five business days of time
of receipt of Buyer's  payment from OPM.  Buyer  retains the right to offset any
amounts  otherwise due Seller under Section 10.3(b) from any such payment.  Such
payment  shall be  accompanied  by a  statement  identifying  the  amount of the
payment from OPM and the specific time period covered by the payment.

     (e) Buyer shall make all filings required to be made by Buyer to effect the
OPM Novation  Agreement within 14 calendar days of the Execution Date,  unless a
later date is requested by Seller. Buyer shall provide Seller with time- stamped
copies of all correspondence  with OPM as proof of compliance with this Section.
Buyer's and OPM's entering into the OPM Novation Agreement is not a condition to
Buyer's obligation to close the transactions contemplated hereby.

10.4.    Employment Matters.

         10.4.1.           Severance Payments.

     (a) Seller  shall  terminate  all of  Seller's  employees  relating  to the
Business (except Consolidated Service Center employees, who shall be transferred
to a Seller's Affiliate on or before Closing) whether such employees are at-will
or are  subject  to  employment  agreements,  as of the  Closing  (collectively,
"Terminated Employees").

     (b) Buyer shall reimburse  Seller for all severance  payments arising under
Seller's  severance  policy in effect on the date of execution of this Agreement
due to those  Terminated  Employees  to whom  Buyer  does not  offer  comparable
employment with comparable pay following their termination from their employment
with Seller  ("Severance  Payments").  Buyer shall also assume the obligation to
provide or pay for all accrued but unused vacation to Terminated Employees,  but
only to the extent such benefits  would be owed under  Seller's  policies and to
the extent adequate reserves have been made in the Closing Balance Sheet. Seller
shall retain the  responsibility to pay any transition bonuses to the Terminated
Employees pursuant to Seller's policies.  If any Terminated Employee is hired by
Buyer pursuant to this Section 10.4.1 and such Terminated  Employee's employment
is severed by Buyer  within 60 days of the Closing  without  cause,  Buyer shall
reimburse Seller for such Terminated Employee severance in an amount which would
have been due the  Terminated  Employee  under  Seller's  severance  policies in
effect on the date of

                                                        35

<PAGE>



     execution  of  this  Agreement  as if  Buyer  had  not  offered  comparable
employment at comparable pay.

     (c)  Promptly   following  the  Execution  Date,  Buyer  (i)  will  provide
information  regarding  its  employment  application  process to the  Terminated
Employees,   and  (ii)  will  actively  begin  to  interview  and  consider  for
employment,  to be  effective  as of the Closing,  any  Terminated  Employee who
submits an  application  for  employment  in accordance  with Buyer's  customary
application process requirements and who are qualified for employment with Buyer
(each individually, an "Applicant," or collectively, "Applicants").

     (d) On or before July 15, 1998,  Buyer shall provide  Seller with a list of
the  Terminated  Employees  that Buyer has elected to hire  effective  as of the
Closing Date, as provided in Section  10.4.2.  Seller shall provide WARN notices
to all  employees  on or before 60 days prior to Closing.  Buyer  shall  provide
Seller,  at the  same  time  Buyer  provides  Seller  with a list of  Terminated
Employees  that Buyer has elected to hire,  with an offer of employment for each
such employee so that Seller may enclose such offer in the WARN notice.

     (e) All  Terminated  Employees who are hired by Buyer shall be given credit
for the time that they were employed by Seller for purposes of calculating  such
Terminated  Employees'  rights under each of Buyer's  employee  benefits  plans,
including without  limitation,  vacation pay, sick pay, and vesting for purposes
of deferred compensation and retirement plans.

     (f) After the Execution Date,  Seller agrees to cooperate with Buyer and to
release  information  to  Buyer  regarding   Terminated  Employees  which  Buyer
considers  for  employment  prior to  Closing.  All  information  regarding  the
Terminated  Employees  shall be provided  subject to (i) all applicable laws and
regulations   regarding   protection  of  the   confidentiality   of  employment
information,  (ii) Buyer's obtaining the written consent of such employees,  and
(iii) Buyer's adherence to any policies of Seller with respect to the protection
of the confidentiality of employee information, as if such policies were Buyer's
own.  Buyer shall respect and protect the  confidentiality  of all such employee
information.

         10.4.2.           WARN, COBRA and HIPAA Notices.

     To the extent  required of Seller by law,  Seller shall provide all notices
relating to the  termination of the  Terminated  Employees,  including,  without
limitation,  the notice  obligations  arising under the Workers  Adjustment  and
Retraining  Notification  Act  ("WARN"),  the  Consolidated  Omnibus  Budget and
Reconciliation  Act of 1985 ("COBRA"),  or the Health Insurance  Portability and
Accountability  Act  of  1996  ("HIPAA").   WARN-  related  liabilities  to  the
Terminated  Employees  which result from any delay in providing  WARN notices to
the Terminated Employees shall be paid by the party causing the delay.

         10.4.3.           Health Care Coverage for Terminated Employees.

     Buyer shall offer health care coverage to all  Terminated  Employees  which
shall be at least  substantially  equivalent  to the health care  coverage  they
would be entitled to receive under COBRA if Seller  remained in existence  after
the  Closing,  effective  as of the date of  Closing,  for a period  of up to 36
months after the Closing Date or such shorter period as permitted by law. To the
extent  that  any  Terminated  Employee  becomes  employed  by  Buyer,  and  the
Terminated  Employee does not meet the eligibility  requirements for Buyer's own
COBRA health care coverage  prior to the Buyer's  termination  of the Terminated
Employee,  Buyer  agrees to offer the  health  care  coverage  set forth in this
Section to such  Terminated  Employee,  effective as of his date of  termination
from Buyer,  until the expiration of the 36th month after the Closing Date. Each
Terminated  Employee  shall  be  responsible  for  payment  of his own  premiums
relating to health care coverage provided pursuant to this Section.

         10.4.4.           Health Care Coverage for Seller's Board of Directors.

     Seller  shall  prepay  through  December 31, 1998 the premiums for whatever
health  care  coverage a member of the Board of  Directors  of Seller  maintains
under Seller's Subscriber Agreements (be it individual, spouse, family, or other
health coverage)  provided Buyer accepts the assignment,  reinsurance,  or other
transfer of such Subscriber  Agreement  under this Agreement.  Buyer shall offer
renewal of such coverage,  without medical  underwriting,  for the calendar year
1999, or until Medicare  eligibility.  Buyer and such individual  shall agree on
the premium payment amount, if any, as Buyer and the individual may agree.

10.5.    Transition Issues.

         10.5.1.           Use of Materials.

     Buyer  shall  have  the  right  to use all  existing  stock  of any and all
advertising brochures,  marketing materials,  literature,  form contracts,  form
certificates of coverage,  membership  handbooks and other pre-printed  material
relating to the  Business,  as  authorized  by law,  until the later of one year
after the Closing Date or (with respect to any particular Subscriber Agreement),
the renewal date for the Member,  or for some other  shorter time  limitation as
may be required by law.  Buyer shall make a  commercially  reasonable  effort to
sticker such materials with Buyer's name to avoid confusion.

         10.5.2.           Transition Agreement.

     On or before the Closing  Seller and Buyer shall enter into the  Transition
Agreement,  in  substantially  the form  attached  hereto as  Exhibit  1.6.1(m),
pursuant to which certain of Seller's  Affiliates will provide Buyer,  for a fee
measured by the direct cost of providing such services,  with certain transition
assistance,  including  membership  accounting,  claims processing,  information
systems training and other administrative support.

10.6.    Public Information Releases.

     Between the Execution Date and the Closing,  and for a period of six months
following the Closing Date, Seller and Buyer agree to use reasonable  efforts to
consult  with each other  prior to any press  release,  public  announcement  or
publicly disseminated communication concerning this transaction,  to discuss the
content  of any such  announcement,  and to refrain  from  making any such press
releases or public  announcements  without  first  receiving  the other's  prior
written  consent,  which shall not be unreasonably  withheld.  The parties shall
develop  and  implement  a  joint  work  plan  for  this  transaction  regarding
communications  with the media. In no event shall either party cause any oral or
written communication to be issued relating to this transaction which disparages
any other party or its  Affiliates,  unless  required by law. The  provisions of
this Section shall survive the termination of this Agreement.

10.7.    Cooperation.

     Buyer and Seller agree to cooperate  reasonably  with each other,  from the
Execution  Date up  through  and  following  the  Closing  Date,  and use  their
respective best efforts in good faith,  to satisfy all conditions,  undertakings
and agreements contained in this Agreement.

10.8.    Group 3000.

     (a) Seller  currently  provides or arranges to provide health care services
to certain  enrollees in Texas ("Texas Group 3000  Members") who are employed by
employers that have  subscriber  agreements  with various  Seller's  Affiliates.
Buyer agrees to continue  Seller's current  practice of providing,  or arranging
for one of Buyer's  Affiliates  to provide,  health  care  services to the Texas
Group  3000  Members  through  the end of the  term  of  each of the  subscriber
agreements covering the Texas Group 3000 Members, in exchange for which Buyer or
Buyer's  Affiliate shall be entitled to charge,  and Seller's  Affiliates  shall
pay, Seller's  standard Group 3000 rates through December 31, 1998.  Thereafter,
Seller's Affiliates agree to pay Buyer a rate actuarially  sufficient to provide
the benefits required by the Subscriber  Agreement.  A copy of Seller's standard
Group 3000 rates is set forth as Exhibit 10.8(a).

     (b) Seller's  Affiliates  currently provide or arrange health care services
to certain  enrollees  outside Texas  ("Non-Texas  Group 3000  Members") who are
employed by Texas employers that have subscriber  agreements with Seller,  which
Subscriber  Agreements  will be  assigned to Buyer  pursuant to this  Agreement.
Seller agrees to cause Seller's Affiliates to continue their current practice of
providing,  or arranging for one of Seller's Affiliates to provide,  health care
services to the Non-Texas Group 3000 Members through the end of the term of each
of the  subscriber  agreements  covering the Non-Texas  Group 3000  Members,  in
exchange for which Seller's  Affiliates  shall be entitled to charge,  and Buyer
shall pay Seller's Affiliates'

                                                        38

     standard  Group 3000 rates  through  December 31, 1998.  Thereafter,  Buyer
agrees to pay Seller's  Affiliates a rate actuarially  sufficient to provide the
benefits required by the Subscriber  Agreement.  A copy of Seller's  Affiliates'
Standard Group 3000 rates is set forth in Exhibit 10.8(b).

     (c) Following the Closing Date,  Seller shall cause Seller's  Affiliates to
make commercially  reasonable efforts not to offer any new or renewal subscriber
agreements  providing for services for Members  located in Texas which  services
would be required to be provided by Buyer absent a separate agreement  providing
for same. In addition,  Buyer shall make commercially  reasonable efforts not to
offer any new or  renewal  agreements  covering  services  for  Members  located
outside of Texas which  would be required to be provided by Seller's  Affiliates
absent a separate agreement providing for same.

10.9.    Reciprocity Agreement.

     Buyer and Seller shall cause their  Affiliates to endeavor in good faith to
enter into  reciprocity  agreements  regarding the provision or  arrangement  of
health care in various states. Failure to enter into such arrangements before or
after the Closing shall not be a condition, covenant, representation,  warranty,
obligation or otherwise  give any party any right or remedy with respect to this
Agreement.

11.      INDEMNIFICATION.

11.1.    Indemnification by Seller.

         Subject to the limitations of Section 11.3,  Seller shall indemnify and
hold harmless Buyer and its respective officers,  directors,  employees,  agents
and affiliates against any and all actual damages resulting from claims, losses,
costs, expenses,  fees, liabilities and damages,  including interest,  penalties
and reasonable  attorneys' fees and disbursements  (each  individually a "Loss,"

         (b)      The Excluded Liabilities;

     (c) The material breach by Seller of any representation, warranty, covenant
or  agreement  made by  Seller  in this  Agreement,  or in any  other  agreement
executed in connection herewith;

     (d) Any claim, obligation or other liability arising from the Business with
respect to any period  prior to the  Closing  Date other than to the extent such
claims,  obligations or liabilities  constitute part of the Assumed Liabilities;
and


                                                        39

<PAGE>



     (e) Any action or litigation which  challenges,  seeks damages arising from
or seeks to enjoin any of the  transactions  contemplated  by this  Agreement or
Related Agreements, other than any actions commenced by shareholders of Buyer or
Buyer's  Affiliates or primarily  involving the operations of Buyer's or Buyer's
Affiliates' businesses.

11.2.    Indemnification by Buyer.

     Subject to the limitations of Section 11.3,  Buyer shall indemnify and hold
harmless Seller and its respective officers,  directors,  employees,  agents and

case  may  be) of  Buyer  or  Buyer's  Affiliates  or  primarily  involving  the
operations of Buyer's or Buyer's Affiliates' businesses which challenges,  seeks
damages arising from or seeks to enjoin any of the transactions  contemplated by
this Agreement or Related Agreements.

11.3.    Limitations.

     The  indemnification  rights and  obligations  set forth in this Section 11
shall  survive the Closing and shall expire 18 months after  Closing;  provided,
however,  that  (i)  with  respect  to  claims  notified  in good  faith  to the
indemnifying party prior to the expiration of the indemnity rights, the parties'
obligations with respect to its indemnity rights and obligations  shall continue
in effect  until  payment  or other  resolution  of such  claims;  and (ii) with
respect to  liabilities  under Section  1.3.2,  the  indemnification  rights and
obligations  shall  continue  until the expiration of the statute of limitations
applicable thereto.  Each party's liability hereunder shall be limited to actual
damages and no party shall be liable to any other party  hereunder  for special,
consequential,  incidental,  punitive or other damages.  Any  indemnified  claim
under Article VII of the Assumption  Reinsurance  Agreement and Article X of the
Insurance Assumption  Reinsurance Agreement shall apply towards the maximums and
minimums set forth in this Section 11.3.

         11.3.1.           Minimum.


                                                        40

<PAGE>



     No party to this Agreement  shall have any liability,  whether  pursuant to
Section  11  or  otherwise,   for  breach  of  any  covenant  or  warranty,  for
misrepresentation,  or otherwise,  unless the aggregate amount of all claims for
which  such  party  would,   but  for  this  Section  11,  be  liable,   exceeds
$1,000,000.00  on a cumulative  basis.  Each claim  making up the  $1,000,000.00
cumulative  amount  shall  be a claim of  $5,000.00  or  more.  If such  party's
aggregate liability for such claims exceeds $1,000,000.00 on a cumulative basis,
then such party shall be liable for all claims,  including claims which are part
of the $1,000,000.00  minimum.  Excluded  Liabilities and reconciliations  under
Section 3.3 of the Assumption  Reinsurance Agreement and Section 3.3 of Schedule
2.5 of the Assumption Reinsurance Agreement or this Agreement are not subject to
and do not count towards these minimum limitations.

         11.3.2.           Maximum.

     In no event shall the  aggregate  liability of any party to this  Agreement
(whether  for breach of  covenant  or  warranty,  misrepresentation  pursuant to
Section  11,  or  otherwise)  exceed  50%  of  the  Purchase  Price,  net of any
adjustments provided by this Agreement. Excluded Liabilities and reconciliations
under  Section 3.3 of the  Assumption  Reinsurance  Agreement and Section 3.3 of
Schedule 2.5 of the Assumption  Reinsurance  Agreement or this Agreement are not
subject to and do not count towards this maximum limitation.

11.4.    Notice and Right to Defend.

     (a) Should any claim or action by a third  party  arise  after the  Closing
Date for which  Buyer or Seller may be liable to the other  under the  indemnity
provisions of this  Agreement,  the  indemnitee  shall notify the  indemnitor in
writing and in reasonable  detail as soon as  practicable  after the  indemnitee
receives notice of such claim or action in the manner provided for the giving of
notices  under  this  Agreement.  The  expenses  of all  proceedings,  contests,
lawsuits,  or  investigations  of claims with respect to such claims or actions,
shall be borne by the indemnitor.  If an indemnitor wishes to assume the defense
of such claim or action,  it shall give written notice to the indemnitee  within
10 days  after  notice  from  the  indemnitee  of such  claim or  action  of its
intention to assume the defense,  and the indemnitor shall thereafter assume the
defense of any such claim or liability through counsel  reasonably  satisfactory
to the  indemnitee,  provided that the indemnitee  may also  participate in such
defense at its own expense;

     (b) If the  indemnitor  shall not  assume  the  defense  of, or if after so
assuming it shall fail to defend,  any such claim or action,  the indemnitee may
defend against any such claim or action in such manner as it may reasonably deem
appropriate and the indemnitee may settle such claim or litigation on such terms
as it may  reasonably  deem  appropriate,  and  the  indemnitor  shall  promptly
reimburse the indemnitee for the amount of all  reasonable  expenses,  legal and
otherwise,  incurred by the  indemnitee  in connection  with the defense  and/or
settlement of such claim or action. If no settlement

                                                        41

<PAGE>



     of such claim or action is made, the indemnitor  shall satisfy any judgment
rendered  with  respect to such claim or in such  action  before  indemnitee  is
required to do so, and pay all  expenses,  legal or  otherwise,  incurred by the
indemnitee in the defense against such claim or litigation.

11.5.    Exclusive Remedy.

     If a party is entitled to indemnification under this Agreement with respect
to a particular claim, then such indemnification  shall be such party's sole and
exclusive remedy.

11.6.    Failure to Provide Records Cooperation.

     If Buyer materially  breaches its obligations under Section 9.1 that Seller
can establish were actually transferred by Seller to Buyer under this Agreement,
and Seller  establishes  that such breach resulted in the loss or destruction of
documents  material to the defense of Buyer by Seller of an action or claim by a
third  party  pursuant  to  Seller's  indemnification   obligations  under  this
Agreement,  Seller  shall be  entitled to recover  from Buyer its actual  losses
incurred in the matter directly resulting from Buyer's breach. The amount of the
losses  recoverable  from Buyer shall in no event exceed the amount of the third
party claim, and shall not include special, consequential,  incidental, punitive
or other damages.

12.      TERMINATION.

12.1.    Termination.

     This Agreement and the transactions  contemplated  hereby may be terminated
or abandoned at any time prior to the Closing Date:

     (a) By the mutual consent of Buyer and Seller; or

     (b) By Seller or Buyer if the Closing  shall not have occurred on or before
October 31, 1998.

     Termination of this Agreement shall terminate the Related Agreements. Where
a Related  Agreement  is only  between  Buyer and Seller,  no further  action or
notice shall be required for such termination to take effect. Where an Affiliate
or a third party is involved in a Related Agreement, Buyer and Seller (as may be
the case) shall cause termination of such Related Agreement.

12.2.    Liability for Termination.

     If this  Agreement is  terminated  pursuant to this Section 12, all further
obligations  of the parties under this  Agreement  shall be  terminated  without
further liability of any party to the other, provided that nothing shall relieve
either party from any liability it may have for any breach hereof.

13.      ARBITRATION.

13.1.    Conciliation and Mediation.

     If a dispute between Buyer and Seller relating to this Agreement,  or under
any other  agreement  executed and  delivered  in  connection  herewith,  is not
resolved  within 15 days from the date that either  party has notified the other
that such  dispute  exists,  then such dispute  shall be  submitted  jointly for
conciliation  to the  president  or his  designee of each party.  If such senior
executive  officers  are unable to resolve the  dispute  within 30 days from the
date that it is first  presented  to them,  either  party may give notice to the
other party that the dispute shall be submitted to non-binding  mediation with a
mediator acceptable to both parties,  and the parties shall, for a 60-day period
from the receipt of such  notice,  seek in good faith to resolve such dispute in
mediation. If the parties are not able to resolve the dispute in mediation, then
such dispute shall be referred to binding arbitration.

13.2.    Arbitration.

     Any dispute  submitted to  arbitration  pursuant to this  Section  shall be
determined by the decision of a board of arbitration consisting of three members
("Board of Arbitration") selected as hereinafter provided. Buyer shall select an
arbitrator and Seller shall select an arbitrator, each of whom shall be a member
of the Board of Arbitration who is independent of the parties.  A third Board of
Arbitration  member,  independent  of the  parties,  shall be selected by mutual
agreement of the other two Board of Arbitration  members. If the other two Board
of  Arbitration  members fail to reach  agreement on such third member within 20
days after their  selection,  such third member shall  thereafter be selected by
the  American  Arbitration  Association  upon  application  made to it for  such
purpose by any party to the arbitration.  The Board of Arbitration shall meet in
Dallas,  Texas, or such other place as a majority of the members of the Board of
Arbitration  determines more appropriate,  and shall reach and render a decision
in writing (which shall state the reasons for its decisions in writing and shall
make such decisions  entirely on the basis of the  substantive law governing the
Agreement  and which shall be  concurred  in by a majority of the members of the
Board of Arbitration)  with respect to the items in dispute.  In connection with
rendering its  decisions,  the Board of  Arbitration  shall adopt and follow the
Commercial  Rules of  Arbitration  of the American  Arbitration  Association  in
effect as of the date of the arbitration, except as provided in Exhibit 13.2. To
the extent practical, decisions of the Board of Arbitration shall be rendered no
more than 30 calendar days following  commencement  of proceedings  with respect
thereto.  The Board of  Arbitration  shall  cause  its  written  decision  to be
delivered  to Buyer and Seller.  Any decision  made by the Board of  Arbitration
(either  prior to or after the  expiration of such 30 calendar day period) shall
be final,  binding and conclusive on Buyer and Seller (except as may be provided
in Exhibit 13.2) and each party to the arbitration  shall be entitled to enforce
such decision to the fullest extent permitted by law and entered in any court of
competent  jurisdiction.  The fees and expenses of the Board of Arbitration  and
the reasonable fees and expenses of legal counsel and consultants of the parties
shall  be  allocated  among  the  parties  as the  Board  of  Arbitration  deems
appropriate.

13.3.    Equitable Relief.

     Notwithstanding any other provision of this Agreement, any party shall have
the right to seek equitable relief, in a court of competent jurisdiction, to the
extent that equitable relief is available to a party hereto.  If a party chooses
to pursue equitable relief,  such conduct shall not constitute a waiver of or be
deemed  inconsistent  with the arbitration  provisions set forth in this Section
13. The Board of  Arbitration  may consider the findings of, rulings of, and any
evidence  submitted in every legal  proceeding for equitable relief as the Board
of Arbitration deems proper;  however,  any such findings,  rulings and evidence
shall not  necessarily be binding on the Board of Arbitration in connection with
any arbitration proceedings conducted by such Board of Arbitration.

13.4.    No Applicability.

     This Section is not  applicable  to disputes  required by the terms of this
Agreement  to be  resolved  pursuant  to the  procedures  set  forth in  Section
1.4.1(e).

14.      GUARANTEES.

notice given pursuant to this Section, or if a notice is not deliverable because
of a changed  address or fax  number of which no notice was given in  accordance
with the provisions hereof,  such notice shall be deemed to be received two days
after  such  notice  was  mailed  (whether  as  the  actual  notice  or  as  the
confirmation  of a faxed  notice)  in  accordance  with the  terms  hereof.  The
foregoing shall not preclude the effectiveness of actual written notice given to
a party at any address or by any means.

15.2.    Waiver.

     No  waiver  by  either  Buyer or  Seller  hereto  of its  rights  under any
provision of this  Agreement  shall  constitute a waiver of such party's  rights
under such  provision at any other time or a waiver of such party's rights under
any other provision of this Agreement.

15.3.    Counterparts.

     This Agreement may be executed in any number of counterparts, each of which
shall be deemed an original but all of which together  shall  constitute one and

     The headings contained in this Agreement have been inserted for convenience
of  reference  only and shall in no way  restrict  or modify any of the terms or
provisions hereof.

15.5.    Severability.

     If any provision of this  Agreement is held by final judgment of a court of
competent  jurisdiction to be invalid,  illegal or unenforceable,  such invalid,
illegal or  unenforceable  provision shall be severed from the remainder of this
Agreement,  and the remainder of this Agreement shall be enforced.  In addition,
the  invalid,   illegal  or  unenforceable  provision  shall  be  deemed  to  be
automatically  modified,  and, as so modified, to be included in this Agreement,
such  modification  being made to the  minimum  extent  necessary  to render the
provision valid, legal and enforceable.  Notwithstanding the foregoing, however,
if the severed or modified  provision concerns all or a portion of the essential
consideration  to be delivered  under this  Agreement by one party to the other,
the remaining  provisions of this Agreement shall also be modified to the extent
necessary to adjust  equitably the parties'  respective  rights and  obligations
hereunder.

assignment in violation of this Section shall be void ab initio.

15.8.    Governing Law.

     This Agreement is to be governed by and  interpreted  under the laws of the
State of Texas,  without  resort to choice of law or conflict of law  principles
which direct the application of the laws of a different state.

     (a) Buyer shall pay the fees, expenses,  and disbursements of Buyer and its

herein shall include the masculine,  feminine, and neuter, and the number of all

                                                        47

     shall include the singular and plural.  All parties to this  Agreement have
been  represented  by counsel  and,  accordingly,  this  Agreement  shall not be
construed  strictly for or against any party hereto.  The Schedules and Exhibits
attached hereto are incorporated herein for all purposes and made a part of this
Agreement as if set out in full in this  Agreement.  All  references  to section
numbers in this  Agreement  shall be references  to sections in this  Agreement,
unless otherwise specifically indicated.

15.12.   Third Parties.

     None of the provisions of this Agreement shall confer rights or benefits as
third  party  beneficiaries  or  otherwise  upon  any  third  party  that is not
expressly  a  party  to  this  Agreement  including,   without  limitation,  the
Terminated  Employees or the Members, and the provisions of this Agreement shall
not be enforceable by any such third party.

15.13.   Time is of the Essence.

     Time  is of the  essence  with  regard  to all of the  provisions  of  this
Agreement.  The parties acknowledge and agree that strict compliance with all of

     The  parties  acknowledge  and agree that this  Agreement  and the  Related
Agreements are part of the  "Confidential  Information"  of the  Confidentiality
Agreement.  Notwithstanding the Confidentiality  Agreement,  which shall survive
the execution of this Agreement, or any confidentiality, proprietary, or similar
clause  in any  Related  Agreement,  the  parties  may  disclose  any  terms  or
conditions of this Agreement to any third parties to comply with securities laws
or HMO or insurance laws, and as needed to meet prudent business requirements of
shareholders, investors, bondholders, members and other creditors.

15.15.   Offsets.

     Either  party may offset any amount  owed the other by amounts  owed by the
other to the party.

15.16.   No Duplication.

     The  intent of the  parties  is that the  Reinsurance  Agreements  and this
Agreement are different  memorializations  of substantially  similar  agreements
between   the   parties,   and   that   the   claims,   offsets,    adjustments,
indemnifications,  reconciliations,  liabilities, rights, and remedies under the
Reinsurance  Agreements  and this  Agreement  shall not be  duplicative.  If any
particular event or circumstances gives rise to any claim,  offset,  adjustment,
indemnification,   reconciliation,   liability,  right,  or  remedy  under  this
Agreement and under one or both of the Reinsurance  Agreements,  Buyer or Seller
must elect to exercise its rights either under this  Agreement or any one of the
Reinsurance

2.1.     Representations and Warranties of Seller.

     As of the  Execution  Date,  Seller  represents  and  warrants  to Buyer as
follows:

         2.1.1.     Organization and Good Standing.



HLTHDAL:19130.4  40072-00002


<PAGE>



     Seller is a professional  association duly organized,  validly existing and
in good standing under the laws of the jurisdiction of its organization, has all
requisite  corporate power and corporate  authority to own lease and operate its
properties  and to carry on its business,  as now being  conducted,  and is duly
qualified and in good standing to do business  under the corporate  laws of each
jurisdiction  in which the nature of its business or the ownership or leasing of
its properties makes such qualification necessary, except when the failure to be
so qualified would not have a Material Adverse Effect.

         2.1.2.     Seller's Authority and No Breach.

     Seller has all requisite  corporate power and corporate  authority to enter
into this Agreement and to consummate the transactions  contemplated hereby. The
execution  and  delivery  of  this  Agreement  and  the   consummation   of  the
transactions  contemplated  hereby have been duly  authorized  by all  necessary
corporate  action of Seller  other than the  approval of  Seller's  Unitholders,
which approval shall be obtained prior to Closing.  This Agreement constitutes a
valid and  binding  obligation  of  Seller,  enforceable  against  Seller in all
material respects in accordance with its terms except insofar as enforcement may
be limited by insolvency or similar laws affecting the enforcement of creditors'
rights in  general,  and  except as  enforceability  may be  limited  by general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

         2.1.3.     No Violations

     Except for consents of third parties  required under contracts set forth on
Part A of Exhibit 1.1, the  execution and delivery of this  Agreement  does not,
and the  consummation  of the  transactions  contemplated  hereby will not,  (i)
conflict  with,  or result in any  material  violation  of, or default  (with or
without  notice  or lapse of time,  or both)  under,  or give rise to a right of
termination, cancellation or acceleration of any material obligation or the loss
of a material  benefit  under,  or the  creation  of a material  lien,  security
interest  or other  encumbrance  with  respect to, any  material  portion of the
Assets or Assumed Liabilities (any such conflict,  violation,  default, right of
termination,  cancellation or  acceleration,  loss or creation,  a "Violation"),
pursuant to any provision of the Articles of  Association or By- laws of Seller,
(ii) result in any Violation of any material agreement which constitutes part of
the  Assets  or  Assumed  Liabilities,  (iii)  result  in any  Violation  of any
judgment,  order or decree entered with respect to Seller or to which the Assets
or the Assumed Liabilities are subject,  or, (iv) to Seller's knowledge,  result
in any Violation of any statute,  law, ordinance,  rule or regulation applicable
to the Assets or the Assumed  Liabilities,  except, in each of subparagraphs (i)
through (iv), where such Violations, individually or in the aggregate, would not
have a Material Adverse Effect.

         2.1.4.     Litigation.



HLTHDAL:19130.4  40072-00002


<PAGE>



     To  Seller's  knowledge,  there  are  no  actions,  suits,  proceedings  or
investigations  of any kind now pending or  threatened  in writing and involving
Seller, the Assets or the Assumed Liabilities, which may have a Material Adverse
Effect.

         2.1.5.     Seller's Financial Statements.

     Seller  has  delivered  to Buyer  complete  and  correct  copies of (i) the
audited  balance sheet of Seller as at December 31, 1996 and the related audited
statements  of income and cash flows for the fiscal  year then  ended,  together
with all footnotes, and (ii) a draft copy of the audited balance sheet of Seller
as at December 31, 1997 and the related draft  audited  statements of income and
cash  flows  for the  fiscal  year  then  ended,  together  with  drafts  of all
footnotes,  which  financial  statements and draft financial  statements  fairly
present  in all  material  respects,  as at and for the  periods  then ended the
financial  position  and  results of  operations  of Seller in  conformity  with
generally  accepted  accounting  principles  prevailing in the United States, in
each case applied on a basis consistent throughout the reported periods.  Seller
has also delivered to Buyer an unaudited  interim balance sheet and statement of
income of Seller for the fiscal period ended on March 31, 1998,  which have been
prepared in a manner  consistent  with prior  practices  for Seller's  unaudited
statements  and on which all  transactions  that are  material are recorded in a
manner that is consistent with the recordation of such transactions in the past.
Such  financial  statements  (i) do not  contain  any item of  extraordinary  or
non-recurring  income or expense  (except as specified  therein) and (ii) do not
reflect any write- off or revaluation  of assets (except as specified  therein),
other than year-end adjustments which individually,  or in the aggregate,  would
not be material.

         2.1.6.     No Brokers or Finders.

     No broker or finder is involved on behalf of Seller in connection  with the
sale of the  Assets,  nor may any broker or finder  involved on behalf of Seller
claim  any  commission  on  account  of the  sale  of the  Assets.  The  parties
acknowledge  that  Wasserstein  Perella & Co.  has been  engaged  by Seller as a
financial advisor to Seller, and the fees of Wasserstein  Perella & Co. shall be
paid for by Seller.

         2.1.7.     Compliance with Applicable Laws.

     Except to the extent that non-compliance  would not have a Material Adverse
Effect,  the  business  of  Seller is being  conducted  in  compliance  with all
applicable laws, rules,  ordinances,  regulations,  licenses,  or judgments,  or
orders,  rules,  regulations,  licenses,  judgments,  or decrees of Governmental
Entities.  Seller has not,  and, to Seller's  knowledge,  none of its  executive
officers,  directors or employees (in their respective  capacities as such), has
engaged in any activity  constituting  fraud or abuse under the laws relating to
health care or insurance.

         2.1.8.     No Consents.

     No  consent,   approval,   order  or  authorization  of,  or  registration,
declaration  or filing with, any court,  administrative  agency or commission or
other  governmental  authority  or  instrumentality,   domestic  or  foreign  (a
"Governmental  Entity"),  is required by or with respect to Seller in connection

         2.1.9.     Material Contracts.

     Each  material  contract  constituting  part of the  Assets or the  Assumed
Liabilities  is in full force and effect and is valid and  enforceable by Seller
in accordance  with its terms,  except insofar as enforcement  may be limited by
bankruptcy,  insolvency or similar laws affecting the  enforcement of creditors'
rights in  general,  and  except as  enforceability  may be  limited  by general
principles of equity (regardless of whether such enforceability is considered in
a  proceeding  in equity or at law).  Seller is not in  material  default in the
observance  or the  performance  of any term or obligation to be performed by it
under any such  agreement to the extent that such default would cause a Material
Adverse  Effect.  To the  knowledge  of Seller,  no other  person is in material
default in the  observance  or the  performance  of any term or obligation to be
performed by it under any such  contract to the extent that such a default would
cause a Material Adverse Effect.  Seller has provided, or will provide before 60
days after the  Execution  Date,  originals  or true and  correct  copies of all
contracts  constituting part of the Assets or Assumed  Liabilities which are not
terminable on 90 days notice or less.

     Seller  has good  title  to the  Assets  set  forth on Parts B, D, and E of
Exhibit  1.1,  whether  owned or leased,  in each case  subject to no  mortgage,
pledge, conditional sales contract, lien, security interest, right of possession
in favor of any third party, claim or other encumbrance  (collectively "Liens"),
and except with respect to leased  property,  the provisions of such leases.  No
representation or warranty is being made with respect to the physical  condition
of the Assets.  Seller makes no representation or warranty with respect to title
to the intellectual property set forth in Part C of Exhibit 1.1.

         2.1.11.    No Untrue Representation or Warranty.

     To  Seller's  Knowledge,  no  representation  or warranty by Seller in this
Agreement,  nor any  statement  or  certificate  furnished or to be furnished to
Buyer pursuant hereto or in connection with the transactions contemplated hereby
by Seller contains or will contain any untrue statement of a material fact.

2.2.     Representations and Warranties True and Correct at Closing; Breaches.

2.1.2, 2.1.5, and 2.1.10, if any of the representations and warranties of Seller
are not true and  correct in all  respects as of the  Closing  Date,  then Buyer
shall be  entitled  to  indemnification  for any and all losses as  provided  in
Section  11  hereof,  but  shall  nevertheless  be  obligated  to  conclude  the
transactions  contemplated  hereby.  The consummation of the transactions  under
this  Agreement  by Buyer  shall not  constitute  a waiver of Buyer's  rights to
indemnification  for a breach of a  representation  or warranty  provided for in
this Section.

binding obligation of Buyer,  enforceable against Buyer in all material respects
in accordance  with its terms,  except insofar as enforcement  may be limited by
insolvency,  or similar laws affected the  enforcement  of creditors'  rights in
general,  and except as enforceability  may be limited by general  principles of
equity (regardless of whether such enforceability is considered in proceeding in
equity or at law).

         3.1.3.     No Brokers or Finders.

by Buyer, or the consummation by Buyer of the transactions  contemplated hereby,
except for such filings, authorizations, orders and approvals as may be required
by state and local  Governmental  Entities,  including  those in connection with
Buyer's insurance business.

         3.1.5.     No Untrue Representation or Warranty.

     To  Buyer's  knowledge,  no  representation  or  warranty  by Buyer in this
Agreement,  nor any  statement  or  certificate  furnished or to be furnished to

warranties of Buyer are not true and correct as of the Closing Date, then Seller
shall be  entitled  to  indemnification  for any and all losses as  provided  in
Section 11. The consummation of the transactions  under this Agreement by Seller
shall not constitute a waiver of Seller's rights to indemnification for a breach
of a representation or warranty provided for in this Section.

4.       SURVIVAL OF REPRESENTATIONS AND WARRANTIES.

     The  representations  and  warranties  of Buyer  and  Seller  contained  in

counsel to the extent  possible  without  waiving any privilege  with respect to
information regarding all actions,  suits,  proceedings or investigations of any

Seller's  severance  policy in effect on the date of execution of this Agreement
due to those  Terminated  Employees  to whom  Buyer  does not  offer  comparable
employment with comparable pay following their termination from their employment
with Seller  ("Severance  Payments").  Buyer shall also assume the obligation to
provide or pay for all accrued but unused vacation to Terminated Employees,  but
only to the extent such benefits would be owed under Seller's  policies.  Seller
shall retain the  responsibility to pay any transition bonuses to the Terminated
Employees pursuant to Seller's policies.  If any Terminated Employee is hired by

Employees,   and  (ii)  will  actively  begin  to  interview  and  consider  for
employment,  to be  effective  as of the Closing,  any  Terminated  Employee who
submits an  application  for  employment  in accordance  with Buyer's  customary
application process requirements and who are qualified for employment with Buyer
(each individually, an "Applicant," or collectively, "Applicants").

     (d) On or before July 15, 1998,  Buyer shall provide  Seller with a list of
the  Terminated  Employees  that Buyer has elected to hire  effective  as of the
Closing Date, as provided in Section  10.2.2.  Seller shall provide WARN notices
to all  employees  on or before 60 days prior to Closing.  Buyer  shall  provide
Seller,  at the  same  time  Buyer  provides  Seller  with a list of  Terminated
Employees  that Buyer has elected to hire,  with an offer of employment for each
such employee so that Seller may enclose such offer in the WARN notice.

     (e) All  Terminated  Employees who are hired by Buyer shall be given credit
for the time that they were employed by Seller for purposes of calculating  such
Terminated  Employees'  rights under each of Buyer's  employee  benefits  plans,
including without  limitation,  vacation pay, sick pay, and vesting for purposes
of deferred compensation and retirement plans.

     (f) After the Execution Date,  Seller agrees to cooperate with Buyer and to

considering  for  employment  prior to Closing.  All  information  regarding the

information.  Information  to be released  hereunder  does not  include  quality
management and peer review  documents,  including but not limited to any and all
credentialing files, utilization review information,  peer evaluations,  medical
record reviews,  and member complaints,  except as may be permitted by law so as

     To the extent  required of Seller by law,  Seller shall provide all notices
relating to the  termination of the  Terminated  Employees,  including,  without
limitation,  the notice  obligations  arising under the Workers  Adjustment  and
Retraining  Notification  Act  ("WARN"),  the  Consolidated  Omnibus  Budget and
Reconciliation  Act of 1985 ("COBRA"),  or the Health Insurance  Portability and
Accountability  Act  of  1996  ("HIPAA").   WARN-  related  liabilities  to  the
Terminated  Employees  which result from any delay in providing  WARN notices to
the Terminated Employees shall be paid by the party causing the delay.

         10.2.3.    Healthcare Coverage for Terminated Employees.

be entitled to receive  under COBRA if Seller  remained in  existence  after the
Closing,  effective  as of the date of Closing,  for a period of up to 36 months
after the Closing Date or such shorter period as permitted by law. To the extent
that any  Terminated  Employee  becomes  employed by Buyer,  and the  Terminated
Employee  does not meet the  eligibility  requirements  for  Buyer's  own  COBRA
healthcare coverage prior to the Buyer's termination of the Terminated Employee,
Buyer agrees to offer the healthcare  coverage set forth in this Section to such
Terminated  Employee,  effective as of his date of termination from Buyer, until
the expiration of the thirty-sixth month after the Closing Date. Each Terminated
Employee  shall be  responsible  for  payment of his own  premiums  relating  to
healthcare coverage provided pursuant to this Section.

10.3.    Cooperation.

     Buyer and Seller agree to cooperate  reasonably  with each other,  from the

     Seller  shall  prepay  through  December 31, 1999 the premiums for whatever
health care coverage  certain  Unitholders  of Seller  maintain  under  KFHPTx's
Subscriber  Agreements,  as defined in the Purchase Agreement (be it individual,
spouse, family, or other health coverage) provided Buyer accepts the assignment,
reinsurance,  or  other  transfer  of  such  Subscriber  Agreements  under  this
Agreement and provided further the Unitholders pay such premiums to Seller.

Liabilities; and

     (e) Any action or litigation which  challenges,  seeks damages arising from
or seeks to enjoin any of the transactions contemplated by this Agreement, other
than any actions  commenced by  shareholders  of Buyer or Buyer's  Affiliates or

<PAGE>



     (e) Any action or litigation  commenced by members or shareholders  (as the
case  may  be) of  Buyer  or  Buyer's  Affiliates  or  primarily  involving  the
operations of Buyer's or Buyer's Affiliates' businesses which challenges,  seeks
damages arising from or seeks to enjoin any of the transactions  contemplated by
this Agreement or Related Agreements.

11.3.    Limitations.

     The  indemnification  rights and  obligations  set forth in this Section 11
shall  survive the Closing and shall expire 18 months after  Closing;  provided,
however,  that  (i)  with  respect  to  claims  notified  in good  faith  to the
indemnifying party prior to the expiration of the indemnity rights, the parties'
obligations with respect to its indemnity rights and obligations  shall continue
in effect  until  payment  or other  resolution  of such  claims;  and (ii) with
respect to  liabilities  under Section  1.3.2,  the  indemnification  rights and
obligations  shall  continue  until the expiration of the statute of limitations
applicable thereto.  Each party's liability hereunder shall be limited to actual
damages and no party shall be liable to any other party  hereunder  for special,
consequential, incidental, punitive or other damages.

         11.3.1.    Minimum.

     No party to this Agreement  shall have any liability,  whether  pursuant to
Section  11  or  otherwise,   for  breach  of  any  covenant  or  warranty,  for
misrepresentation,  or otherwise,  unless the aggregate amount of all claims for
which such party would, but for this Section 11, be liable,  exceeds $350,000 on
a cumulative basis. Each claim making up the $350,000  cumulative amount must be
a claim of $5,000 or more. If such party's  aggregate  liability for such claims
exceeds $350,000 on a cumulative  basis, then such party shall be liable for all
such claims in excess of $350,000.  Excluded  Liabilities are not subject to and
do not count towards these minimum limitations.

         11.3.2.    Maximum.

     In no event shall the  aggregate  liability of any party to this  Agreement
(whether  for breach of covenant  or  warranty,  misrepresentation,  pursuant to
Section 11 or otherwise) exceed 50% of the Purchase Price.  Excluded Liabilities
are not subject to and do not count towards these maximum limitations.

11.4.    Notice and Right to Defend.

     (a) Should any claim or action by a third party arise after the Closing for
which Buyer or Seller may be liable to the other under the indemnity  provisions
of this Agreement,  the indemnitee shall notify the indemnitor in writing and in
reasonable detail as soon as practicable after the indemnitee receives notice of
such claim or action in the manner provided for the giving of notices under this
Agreement.   The   expenses  of  all   proceedings,   contests,   lawsuits,   or
investigations of claims with respect to such claims or actions,  shall be borne
by the indemnitor.  If an indemnitor  wishes to assume the defense of such claim
or action,  it shall give written notice to the indemnitee  within ten (10) days
after  notice from the  indemnitee  of such claim or action of its  intention to
assume the defense,  and the indemnitor shall  thereafter  assume the defense of
any such claim or  liability  through  counsel  reasonably  satisfactory  to the
indemnitee, provided that the indemnitee may also participate in such defense at
its own expense.

     (b) If the  indemnitor  shall not  assume  the  defense  of, or if after so
assuming it shall fail to defend,  any such claim or action,  the indemnitee may
defend against any such claim or action in such manner as it may reasonably deem
appropriate and the indemnitee may settle such claim or litigation on such terms
as it may  reasonably  deem  appropriate,  and  the  indemnitor  shall  promptly
reimburse the indemnitee for the amount of all  reasonable  expenses,  legal and
otherwise,  incurred by the  indemnitee  in connection  with the defense  and/or
settlement of such claim or action.  If no settlement of such claim or action is
made,  the indemnitor  shall satisfy any judgment  rendered with respect to such
claim or in such  action  before  indemnitee  is  required to do so, and pay all
expenses, legal or otherwise,  incurred by the indemnitee in the defense against
such claim or litigation.

11.5.    Exclusive Remedy.

     If a party is entitled to indemnification under this Agreement with respect
to a particular claim, then such indemnification  shall be such party's sole and
exclusive remedy.

11.6.    Failure to Provide Records Cooperation.

     If Buyer materially  breaches its obligations under Section 9.2 that Seller
can establish were actually transferred by Seller to Buyer under this Agreement,
and Seller  establishes  that such breach resulted in the loss or destruction of
documents  material to the defense of Buyer by Seller of an action or claim by a
third  party  pursuant  to  Seller's  indemnification   obligations  under  this
Agreement,  Seller  shall be  entitled to recover  from Buyer its actual  losses
incurred in the matter directly resulting from Buyer's breach. The


HLTHDAL:19130.4  40072-00002


<PAGE>



     amount of the losses  recoverable  from Buyer shall in no event  exceed the
amount of the third party claim, and shall not include  special,  consequential,
incidental, punitive or other damages.

12.      TERMINATION.

12.1.    Termination.

This Agreement and the transactions contemplated hereby may be terminated or
abandoned at any time prior to the Closing Date:

     (a) By the mutual consent of Buyer and Seller;

     (b) By Seller or Buyer if the Closing  shall not have occurred on or before
October 31,  1998 (or such later date as may be mutually  agreed to by Buyer and
Seller);

     Termination of this Agreement shall terminate the Related Agreements. Where
a Related  Agreement  is only  between  Buyer and Seller,  no further  action or
notice shall be required for such termination to take effect. Where an affiliate
or a third party is involved in a Related Agreement, Buyer and Seller (as may be
the case) shall cause termination of such Related Agreement.

12.2.    Liability for Termination.

     If this  Agreement is  terminated  pursuant to this Section 12, all further
obligations  of the parties under this  Agreement  shall be  terminated  without
further liability of any party to the other, provided that nothing shall relieve
either party from any liability it may have for any breach hereof. 

13.      ARBITRATION.

13.1.    Conciliation and Mediation.

     If a dispute  between Buyer and Seller  relating to this Agreement or under
any other agreement  executed and delivered in connection with this Agreement is
not  resolved  within  fifteen  (15) days from the date  that  either  party has
notified  the other  that  such  dispute  exists,  then  such  dispute  shall be
submitted  jointly for  conciliation  to the  President  or his designee of each
party.  If such  senior  executive  officers  are unable to resolve  the dispute
within thirty (30) days from the date that it is first presented to them, either
party may give notice to the other party that the dispute  shall be submitted to
non- binding  mediation  with a mediator  acceptable  to both  parties,  and the
parties shall, for a sixty (60) day period from the receipt of such notice, seek
in good faith to resolve such dispute in mediation.  If the parties are not able
to resolve  the dispute in  mediation,  then such  dispute  shall be referred to
binding arbitration, except to the extent that injunctive relief is available to
a party hereto.

<PAGE>




13.2.    Arbitration.

     Any dispute  submitted to  arbitration  pursuant to this  Section  shall be
determined  by the decision of a board of  arbitration  consisting  of three (3)
members (ABoard of Arbitration")  selected as hereinafter provided.  Buyer shall
select an arbitrator and Seller shall select an  arbitrator,  each of whom shall
be a member of the Board of Arbitration  who is  independent  of the parties.  A
third Board of Arbitration member, independent of the parties, shall be selected
by mutual agreement of the other two Board of Arbitration  members. If the other
two Board of  Arbitration  members fail to reach  agreement on such third member
within  twenty  (20)  days  after  their  selection,  such  third  member  shall
thereafter be selected by the American Arbitration  Association upon application
made to it for such  purpose  by any  party  to the  arbitration.  The  Board of
Arbitration  shall meet in Dallas,  Texas,  or such other place as a majority of
the members of the Board of Arbitration  determines more appropriate,  and shall
reach and render a decision  in writing  (which  shall state the reasons for its
decisions in writing and shall make such decisions  entirely on the basis of the
substantive  law  governing  the  Agreement and which shall be concurred in by a
majority of the members of the Board of  Arbitration)  with respect to the items
in dispute. In connection with rendering its decisions, the Board of Arbitration
shall  adopt and follow the  Commercial  Rules of  Arbitration  of the  American
Arbitration  Association,  except as  provided  in Exhibit  13.2.  To the extent
practical,  decisions of the Board of Arbitration shall be rendered no more than
thirty (30) calendar days following  commencement  of  proceedings  with respect
thereto.  The Board of  Arbitration  shall  cause  its  written  decision  to be
delivered  to Buyer and Seller.  Any decision  made by the Board of  Arbitration
(either  prior to or after the  expiration  of such  thirty  (30)  calendar  day
period)  shall be final,  binding  and  conclusive  on Buyer and Seller and each
party to the  arbitration  shall be  entitled  to enforce  such  decision to the
fullest  extent  permitted  by  law  and  entered  in  any  court  of  competent
jurisdiction.  The  fees  and  expenses  of the  Board  of  Arbitration  and the
reasonable  fees and expenses of legal  counsel and  consultants  of the parties
shall be allocated  among the parties in the same  proportion that the aggregate
amount of the disputed  items so submitted to the Board of  Arbitration  that is
unsuccessfully  submitted by each of them (as finally determined by the Board of
Arbitration)  bears to the total amount of items so submitted.  

13.3.  Equitable Relief.

     Notwithstanding any other provision of this Agreement, any party shall have
the right to seek equitable relief, in a court of competent jurisdiction, to the
extent that equitable relief is available to a party hereto.  If a party chooses
to pursue equitable relief,  such conduct shall not constitute a waiver of or be
deemed  inconsistent  with the arbitration  provisions set forth in this Section
13. The Board of  Arbitration  may consider the findings of, rulings of, and any
evidence  submitted in every legal  proceeding for equitable relief as the Board
of Arbitration deems proper;  however,  any such findings,  rulings and evidence
shall not  necessarily be binding on the Board of Arbitration in connection with
any arbitration proceedings conducted by such Board of Arbitration.

party shall be prohibited  from  disclosing  any such  information,  without the
other party's consent, if such disclosure is required, in the reasonable opinion
of its legal  counsel,  by order of a court of competent  jurisdiction  or under
applicable law or regulatory action and the disclosing party has given notice of
such  requirement to the other party promptly upon learning that such disclosure
may be  required  and (ii) Buyer shall not be  prohibited  from  disclosing  any

any other provision of this Agreement.

14.4.    Counterparts.

     This Agreement may be executed in any number of counterparts, each of which

necessary to adjust  equitably the parties'  respective  rights and  obligations
hereunder.

                                   As Amended and Restated through May 18, 1998


     1. Purpose.  The purpose of this 1995 Long-Term  Incentive Plan, as amended
and restated (the "Plan"), of Sierra Health Services, Inc., a Nevada corporation
(the "Company"), is to advance the interests of the Company and its stockholders
by providing a means to attract, retain, and reward executive officers and other
key  employees of, and  consultants  to, the Company and its  subsidiaries,  and
directors of  subsidiaries,  to link  compensation  to measures of the Company's
performance in order to provide  additional  incentives,  including  stock-based
incentives and cash-based annual incentives, to such persons for the creation of
stockholder  value,  and to  enable  such  persons  to  acquire  or  increase  a
proprietary  interest  in the  Company in order to promote a closer  identity of
interests between such persons and the Company's stockholders.

     2.  Definitions.  The  definitions  of awards  under  the  Plan,  including

granted as a bonus or in lieu of other awards, and Other Stock-Based Awards, are
set forth in Section 6 of the Plan, and the definition of Performance Awards and
Annual  Incentive  Awards is set forth in  Section 8 of the Plan.  Such  awards,
together  with any other right or interest  granted to a  Participant  under the

laws of descent and distribution to receive such benefits.

     (c) "Board" means the Board of Directors of the Company.

     (d) "Code" means the Internal Revenue Code of 1986, as amended from time to

property,  the  fair  market  value of such  Stock,  Awards,  or other  property
determined by such methods or procedures  as shall be  established  from time to
time by the Committee.  Unless otherwise  determined by the Committee,  the Fair

share of common stock  reported in the table  entitled "New York Stock  Exchange

     (i)  "Participant"  means a person  who,  as an  executive  officer  or key
employee of the  Company or a  subsidiary,  has been  granted an Award under the

     (j) "Rule  16b-3"  means  Rule  16b-3,  as from time to time in effect  and
applicable  to the Plan and  Participants,  promulgated  by the  Securities  and
Exchange Commission under Section 16 of the Exchange Act.

     (k) "Stock"  means the Common  Stock,  $.005 par value,  of the Company and

3.       Administration.

     (a)  Authority  of the  Committee.  The Plan shall be  administered  by the

following actions, in each case subject to and consistent with the provisions of
the Plan:


Amended95LTIP071698


<PAGE>



(i)      to select Participants to whom Awards may be granted;

     (ii) to  determine  the type or  types  of  Awards  to be  granted  to each
Participant;

     (iii) to determine the number of Awards to be granted, the number of shares
of Stock to which an Award will relate, the cash amount payable in settlement of
an Annual Incentive Award and the performance conditions applicable thereto, all
other terms and conditions of any Award granted under the Plan  (including,  but
not limited  to, any  exercise  price,  grant  price,  or  purchase  price,  any
restriction or condition,  any schedule or performance  conditions for the lapse
of  restrictions  or  conditions   relating  to   transferability,   forfeiture,
exercisability,  or  settlement  of an Award,  and  waivers,  accelerations,  or
modifications  thereof,  based  in  each  case  on  such  considerations  as the
Committee shall determine), and all other matters to be determined in connection
with an Award;

     (iv) to determine whether,  to what extent, and under what circumstances an
Award may be settled,  or the exercise  price of an Award may be paid,  in cash,
Stock, other Awards, or other property, or an Award may be cancelled, forfeited,
or  surrendered;  

(v) to  determine  whether,  to what  extent,  and under  what
circumstances  cash, Stock, other Awards, or other property payable with respect
to an Award  will be  deferred  either  automatically,  at the  election  of the
Committee, or at the election of the Participant;

     (vi) to  prescribe  the form of each  Award  Agreement,  which  need not be
identical for each Participant;

     (vii)  to  adopt,  amend,  suspend,  waive,  and  rescind  such  rules  and
regulations  and appoint  such agents as the  Committee  may deem  necessary  or
advisable to administer the Plan;

     (viii) to correct  any  defect or supply  any  omission  or  reconcile  any
inconsistency  in the Plan and to construe and interpret the Plan and any Award,
rules and regulations, Award Agreement, or other instrument hereunder; and

     (ix) to make all other  decisions  and  determinations  as may be  required
under the terms of the Plan or as the Committee may deem  necessary or advisable
for the administration of the Plan.

     (b) Manner of Exercise of Committee Authority.  Any action of the Committee
with respect to the Plan shall be final, conclusive, and binding on all persons,
including the Company,  subsidiaries  of the Company,  Participants,  any person
claiming  any  rights  under  the Plan  from or  through  any  Participant,  and
stockholders.  The express grant of any specific power to the Committee, and the
taking of any action by the  Committee,  shall not be  construed as limiting any
power or authority of the  Committee.  The Committee may delegate to officers or
managers of the Company or any subsidiary of the Company the authority,  subject
to such terms as the Committee shall determine, to perform such functions as the
Committee may determine,  to the extent that such  delegation will not result in
the  loss  of  an  exemption  under  Rule  16b-3(d)(1)  for  Awards  granted  to
Participants

Amended95LTIP071698


<PAGE>



     subject to Section 16 of the  Exchange  Act in respect of the  Company  and
will not cause Awards  intended to qualify as  "performance-based"  compensation
under Code Section  162(m) to fail to so qualify,  and as  otherwise  limited by
applicable  law.  Other  provisions of the Plan  notwithstanding,  the Board may
perform any function of the  Committee  under the Plan,  in order to ensure that
transactions under the Plan are exempt under Rule 16b-3 or for any other reason;
provided,  however, that authority  specifically reserved to the Board under the
terms of the Plan, the Company's  Certificate of  Incorporation  or By-laws,  or
applicable law shall be exercised by the Board and not by the Committee.

     (c) Limitation of Liability. Each member of the Committee shall be entitled
to, in good faith, rely or act upon any report or other information furnished to
him by any  officer or other  employee  of the  Company or any  subsidiary,  the
Company's   independent   certified   public   accountants,   or  any  executive
compensation  consultant,  legal counsel, or other professional  retained by the
Company to assist in the administration of the Plan. No member of the Committee,
nor any officer or employee  of the Company  acting on behalf of the  Committee,
shall be  personally  liable for any action,  determination,  or  interpretation
taken or made in good faith with  respect  to the Plan,  and all  members of the
Committee  and any officer or  employee  of the Company  acting on behalf of the
Committee or members  thereof  shall,  to the extent  permitted by law, be fully
indemnified  and  protected  by the  Company  with  respect to any such  action,
determination, or interpretation.

     4.  Stock  Available  Under  the  Plan;   Per-Person   Award   Limitations;
Adjustments.

     (a) Stock  Reserved  for  Awards.  Subject  to  adjustment  as  hereinafter
provided,  the  total  number  of shares of Stock  reserved  and  available  for
issuance to  Participants  in  connection  with  Awards  under the Plan shall be
3,150,000  plus the number of shares  reserved for the grant of awards under the
Company's Second Amended and Restated 1986 Stock Option Plan and Second Restated
Capital  Accumulation  Plan but which have not been and will not be issued under
such plans (as determined at any time during the  effectiveness of the Plan). No
Award may be granted if the number of shares to which such Award  relates,  when
added to the number of shares to which  other  then-outstanding  Awards  relate,
exceeds the number of shares then  remaining  available for issuance  under this
Section 4. If all or any portion of an Award is  forfeited,  settled in cash, or
otherwise  terminated without issuance of shares to the Participant,  the shares
to which such Award or portion  thereof  related  shall again be  available  for
Awards under the Plan; provided, however, that shares withheld in payment of the
exercise price of any Option or withholding  taxes relating to Awards and shares
equal to the number of Shares  surrendered  in payment of the exercise  price of
any Option or withholding  taxes relating to Awards shall,  for purposes of this
provision,  be deemed not to have been issued to the  Participant  in connection
with such Awards under the Plan.  The  Committee  may adopt  procedures  for the
counting of shares  relating  to any Award to ensure  appropriate  counting  and
avoid double counting (in the case of tandem or substitute  awards).  Any shares
of Stock  issued  pursuant  to an Award  may  consist,  in whole or in part,  of
authorized  and unissued  shares,  treasury  shares,  or shares  acquired in the
market for the account of the  Participant  (which  treasury  shares or acquired
shares will be deemed to have been "issued" pursuant to such Award).

Amended95LTIP071698


<PAGE>




     (b) Annual Individual Limitations. During any calendar year, no Participant
may be granted  Options,  SARs,  and other Awards under the Plan with respect to
more than 300,000 shares of Stock,  subject to adjustment as provided in Section
4(c).  For purposes of this Section 4(b),  unless more  restrictive  counting is
required in order for Awards to comply  with the  requirements  of Code  Section
162(m) and regulations thereunder,  this provision will limit the maximum number
of  shares  that can be  issued  to a  Participant  under  Awards  (taking  into
consideration the terms of the Awards, including tandem exercise provisions). In
addition,  no Annual  Incentive  Award or Awards  granted  to a  Participant  in
respect of any one  calendar  year may be  settled by payment of an amount  that
exceeds four percent of the Company's pre-tax operating income (determined under
generally accepted accounting principles) for that year.

     (c)  Adjustments.  In the event that the Committee shall determine that any
dividend or other distribution in the form of Stock or property other than cash,
other   special,   large,   and   non-recurring   dividends  or   distributions,
recapitalization,    forward   or   reverse   split,   reorganization,   merger,
consolidation,  spin-off,  combination,  repurchase, or share exchange, or other
similar  corporate  transaction  or  event,  affects  the  Stock  such  that  an
adjustment is  appropriate  in order to prevent  dilution or  enlargement of the
rights of Participants  under the Plan, then the Committee shall, in such manner
as it may deem equitable, adjust any or all of (i) the number and kind of shares
of Stock  reserved and available for Awards under Section 4(a),  (ii) the number
and kind of shares of  outstanding  Restricted  Stock or  relating  to any other
outstanding  Award in connection  with which shares have been issued,  (iii) the
number and kind of shares  that may be issued in  respect  of other  outstanding
Awards,  (iv) the exercise price, grant price, or purchase price relating to any
Award (or, if deemed  appropriate,  the Committee may make  provision for a cash
payment with  respect to any  outstanding  Award),  and (v) the number of shares
with  respect  to which  Options,  SARs,  and other  Awards  may be granted to a
Participant in any calendar year, as set forth in Section 4(b). In addition, the
Committee is authorized to make  adjustments in the terms and conditions of, and
the criteria included in, Awards (including  Performance  Awards and performance
goals, and Annual Incentive Awards and any performance  goals relating  thereto)
in recognition of unusual or nonrecurring events (including, without limitation,
events  described  in the  preceding  sentence)  affecting  the  Company  or any
subsidiary or the financial  statements of the Company or any subsidiary,  or in
response to changes in applicable laws,  regulations,  or accounting principles.
The foregoing  notwithstanding,  no adjustments  shall be authorized  under this
Section 4(c) with respect to ISOs or SARs in tandem therewith to the extent that
such  authority  would  cause the Plan or such  Awards  to fail to  comply  with
Section 422 of the Code, and no such adjustment shall be authorized with respect
to Options,  SARs, Annual Incentive Awards, or other Awards subject to Section 8
to the extent that such authority would cause such Awards intended to qualify as
"qualified  performance-based  compensation"  under Section  162(m)(4)(C) of the
Code and regulations thereunder to fail to so qualify.

     5. Eligibility.  Executive  officers and other key employees of the Company
and its  subsidiaries  (including  any  director  of the  Company who is also an
executive  officer or key  employee),  and  consultants  to the  Company and its
subsidiaries and directors of any subsidiary (excluding any

Amended95LTIP071698


<PAGE>



     director of the Company who would be eligible solely due to service as such
a consultant or subsidiary  director),  are eligible to be granted  Awards under
the Plan.  The foregoing  notwithstanding,  no member of the Committee  shall be
eligible to be granted Awards under the Plan.

     6. Specific Terms of Awards.

     (a) General. Awards may be granted on the terms and conditions set forth in
this  Section  6. In  addition,  the  Committee  may  impose on any Award or the
exercise thereof, at the date of grant or thereafter (subject to Section 10(e)),
such additional terms and conditions,  not  inconsistent  with the provisions of
the Plan, as the Committee shall determine, including terms requiring forfeiture
of  Awards  in  the  event  of  termination  of  employment  or  service  by the
Participant or upon the occurrence of other events. Except as expressly provided
by the Committee  (including for purposes of complying with  requirements of the
Nevada General Corporation Law relating to lawful  consideration for issuance of
shares), no consideration other than for services will be required for the grant
(but not the exercise) of any Award.

     (b) Options.  The Committee is authorized to grant Options to  Participants
(including "reload" options  automatically granted to offset specified exercises
of options) on the following terms and conditions:

     (i) Exercise Price. The exercise price per share of Stock purchasable under
an Option shall be determined by the Committee;  provided, however, that, except
as provided in Section 7(a), such exercise price shall be not less than the Fair
Market Value of a share on the date of grant of such Option.

     (ii) Time and Method of Exercise. The Committee shall determine the time or
times at which an Option may be  exercised  in whole or in part,  the methods by
which  such  exercise  price may be paid or deemed to be paid,  the form of such
payment,  including,  without  limitation,  cash, Stock,  other Awards or awards
granted under other Company plans, or other property  (including  notes or other
contractual  obligations of  Participants  to make payment on a deferred  basis,
such as through  "cashless  exercise"  arrangements,  to the extent permitted by
applicable  law),  and the methods by which Stock will be delivered or deemed to
be delivered to Participants.

     (iii) ISOs. The terms of any ISO granted under the Plan shall comply in all
respects  with the  provisions  of Section  422 of the Code,  including  but not
limited  to the  requirement  that no ISO shall be  granted  more than ten years
after the  effective  date of the  Plan.  Anything  in the Plan to the  contrary
notwithstanding,  no term of the Plan  relating  to ISOs  shall be  interpreted,
amended,  or altered,  nor shall any  discretion or authority  granted under the
Plan be exercised,  so as to disqualify either the Plan or any ISO under Section
422  of  the  Code,   unless   the   Participant   has  first   requested   such
disqualification.

     (c) Stock Appreciation Rights. The Committee is authorized to grant SARs to
Participants on

Amended95LTIP071698


<PAGE>



the following terms and conditions:

     (i) Right to Payment.  An SAR shall confer on the Participant to whom it is
granted a right to receive,  upon exercise  thereof,  the excess of (A) the Fair
Market Value of one share of Stock on the date of exercise (or, if the Committee
shall so  determine  in the case of any such right  other than one related to an
ISO,  the Fair Market  Value of one share at any time during a specified  period
before or after the date of  exercise),  over (B) the grant  price of the SAR as
determined by the Committee as of the date of grant of the SAR, which, except as
provided in Section  7(a),  shall be not less than the Fair Market  Value of one
share of Stock on the date of grant.

     (ii) Other Terms.  The Committee shall determine the time or times at which
an SAR may be exercised in whole or in part,  the method of exercise,  method of
settlement,  form of consideration payable in settlement,  method by which Stock
will be delivered or deemed to be delivered to  Participants,  whether or not an
SAR shall be in tandem with any other Award,  and any other terms and conditions
of any SAR.  Limited SARs that may only be exercised  upon the  occurrence  of a
Change of Control  (as such term is defined  in  Section  10(b) or as  otherwise
defined by the Committee) may be granted on such terms,  not  inconsistent  with
this Section  6(c), as the  Committee  may  determine.  Such Limited SARs may be
either freestanding or in tandem with other Awards.

     (d) Restricted Stock. The Committee is authorized to grant Restricted Stock
to Participants on the following terms and conditions:

     (i) Grant and  Restrictions.  Restricted  Stock  shall be  subject  to such
restrictions on transferability and other restrictions, if any, as the Committee
may impose,  which  restrictions  may lapse separately or in combination at such
times,  under such  circumstances,  in such  installments,  or  otherwise as the
Committee may determine;  provided,  however, that Restricted Stock the grant of
which is not conditioned upon achievement of any performance  objective shall be
subject to a  restriction  on  transferability  and a risk of  forfeiture  for a
period of not less than three  years  after the date of grant  (except  that the
Committee  may  accelerate  the lapse of such  restrictions  in the event of the
Participant's  termination  of employment  or service due to death,  disability,
normal or approved early retirement,  or involuntary  termination by the Company
or a subsidiary  without  "cause," as defined by the  Committee).  Except to the
extent  restricted under the terms of the Plan and any Award Agreement  relating
to the Restricted Stock, a Participant  granted  Restricted Stock shall have all
of the rights of a stockholder including,  without limitation, the right to vote
Restricted Stock or the right to receive dividends thereon.

     (ii)  Forfeiture.  Except as otherwise  determined by the  Committee,  upon
termination of employment or service during the applicable  restriction  period,
Restricted Stock that is at that time subject to restrictions shall be forfeited
and  reacquired  by the  Company;  provided,  however,  that the  Committee  may
provide,  by rule or regulation or in any Award  Agreement,  or may determine in
any individual  case,  that  restrictions or forfeiture  conditions  relating to
Restricted Stock will be waived in whole or in part in the event of terminations
resulting from specified causes, except as otherwise

Amended95LTIP071698


<PAGE>



provided in Section 6(d)(i).

     (iii)  Certificates for stock.  Restricted Stock granted under the Plan may
be evidenced in such manner as the Committee  shall  determine.  If certificates
representing  Restricted  Stock are  registered in the name of the  Participant,
such  certificates  shall bear an  appropriate  legend  referring  to the terms,
conditions,  and restrictions  applicable to such Restricted  Stock, the Company
shall retain physical  possession of the certificate,  and the Participant shall
have delivered a stock power to the Company,  endorsed in blank, relating to the
Restricted Stock.

     (iv) Dividends and Distributions.  Dividends paid on Restricted Stock shall
be either paid at the dividend payment date in cash or in shares of unrestricted
Stock having a Fair Market Value equal to the amount of such  dividends,  or the
payment of such dividends  shall be deferred  and/or the amount or value thereof
automatically  reinvested in additional Restricted Stock, other Awards, or other
investment vehicles,  as the Committee shall determine or permit the Participant
to elect.  Stock distributed in connection with a Stock split or Stock dividend,
and other property  distributed as a dividend,  shall be subject to restrictions
and a risk of forfeiture to the same extent as the Restricted Stock with respect
to which such Stock or other property is distributed.

     (e) Deferred Stock.  The Committee is authorized to grant Deferred Stock to
Participants, subject to the following terms and conditions:

     (i) Award and Restrictions. Issuance of Stock will occur upon expiration of
the deferral  period  specified for an Award of Deferred  Stock by the Committee
(or, if permitted by the Committee, as elected by the Participant). In addition,
Deferred  Stock  shall be  subject to such  restrictions  as the  Committee  may
impose,  if any, which  restrictions may lapse at the expiration of the deferral
period or at earlier specified times,  separately or in combination,  under such
circumstances,   in  such  installments,  or  otherwise  as  the  Committee  may
determine.

     (ii)  Forfeiture.  Except as otherwise  determined by the  Committee,  upon
termination of employment or service during the  applicable  deferral  period or
portion thereof to which  forfeiture  conditions apply (as provided in the Award
Agreement  evidencing  the Deferred  Stock),  all Deferred Stock that is at that
time subject to such risk of forfeiture shall be forfeited;  provided,  however,
that the Committee may provide, by rule or regulation or in any Award Agreement,
or may  determine  in any  individual  case,  that  restrictions  or  forfeiture
conditions  relating to Deferred Stock will be waived in whole or in part in the
event of terminations resulting from specified causes.

     (iii) Dividend Equivalents.  The Committee may provide that payments in the
form of dividend  equivalents  will be  credited  in respect of Deferred  Stock,
which amounts may be paid or  distributed  when accrued or deemed  reinvested in
additional Deferred Stock.

     (f) Bonus Stock and Awards in Lieu of Cash  Obligations.  The  Committee is
authorized to grant Stock as a bonus,  or to grant Stock or other Awards in lieu
of Company obligations to pay cash

Amended95LTIP071698


<PAGE>



     under other plans or  compensatory  arrangements.  Stock or Awards  granted
hereunder  shall be subject to such other  terms as shall be  determined  by the
Committee.

     (g) Other  Stock-Based  Awards.  The  Committee is  authorized,  subject to
limitations  under  applicable law, to grant to  Participants  such other Awards
that may be  denominated  or payable in, valued in whole or in part by reference
to, or otherwise  based on, or related to, Stock and factors that may  influence
the  value of  Stock,  as  deemed by the  Committee  to be  consistent  with the
purposes of the Plan, including, without limitation, convertible or exchangeable
debt securities,  other rights convertible or exchangeable into Stock,  purchase
rights for Stock,  Awards with value and payment  contingent upon performance of
the Company or any other factors designated by the Committee,  and Awards valued
by  reference  to the book value of Stock or the value of  securities  of or the
performance of specified  subsidiaries.  The Committee shall determine the terms
and conditions of such Awards.  Stock issued  pursuant to an Award in the nature
of a purchase  right granted under this Section 6(g) shall be purchased for such
consideration,  paid for at such  times,  by such  methods,  and in such  forms,
including,  without limitation, cash, Stock, other Awards, or other property, as
the Committee shall  determine.  Cash awards,  as an element of or supplement to
any other Award under the Plan, may be granted pursuant to this Section 6(g).

7.       Certain Provisions Applicable to Awards.

     (a) Stand-alone,  Additional, Tandem, and Substitute Awards. Awards granted
under the Plan may, in the discretion of the Committee,  be granted either alone
or in addition  to, in tandem  with,  or in  substitution  for,  any other Award
granted under the Plan or any award granted under any other plan of the Company,
any  subsidiary,  or any  business  entity to be  acquired  by the  Company or a
subsidiary,  or any other right of a  Participant  to receive  payment  from the
Company or any subsidiary. Awards granted in addition to or in tandem with other
Awards or awards  may be  granted  either as of the same time as or a  different
time from the grant of such other Awards or awards. The per share exercise price
of any Option,  grant  price of any SAR,  or  purchase  price of any other Award
conferring a right to purchase Stock granted in substitution  for an outstanding
Award  or  award  may be  adjusted  to  reflect  the  in-the-money  value of the
surrendered Award or award.

     (b) Term of Awards.  The term of each Award shall be for such period as may
be determined by the Committee;  provided,  however,  that in no event shall the
term of any ISO or an SAR  granted  in tandem  therewith  exceed a period of ten
years from the date of its grant (or such  shorter  period as may be  applicable
under Section 422 of the Code).

     (c) Form of Payment Under Awards.  Subject to the terms of the Plan and any
applicable Award  Agreement,  payments to be made by the Company or a subsidiary
upon  the  grant  or  exercise  of an  Award  may be made in such  forms  as the
Committee shall determine,  including,  without  limitation,  cash, Stock, other
Awards, or other property,  and may be made in a single payment or transfer,  in
installments,  or on a  deferred  basis.  Such  payments  may  include,  without
limitation,  provisions  for the payment or crediting of reasonable  interest on
installment or deferred payments or the grant or

Amended95LTIP071698


<PAGE>



     crediting of dividend  equivalents  in respect of  installment  or deferred
payments denominated in Stock.

(d)      Rule 16b-3 Compliance.

     (i) Six-Month Holding Period.  Unless a Participant could otherwise dispose
of equity securities (including  derivative  securities) acquired under the Plan
without  incurring  liability  under Section  16(b) of the Exchange Act,  equity
securities  acquired  under  the Plan  must be held for a period  of six  months
following the date of such  acquisition,  provided that this condition  shall be
satisfied  with respect to a derivative  security if at least six months  elapse
from  the  date  of  acquisition  of the  derivative  security  to the  date  of
disposition of the derivative  security (other than upon exercise or conversion)
or its underlying equity security.

     (ii)  Compliance  Generally.  With  respect  to a  Participant  who is then
subject to the  reporting  requirements  of Section 16(a) of the Exchange Act in
respect of the Company,  the Committee  shall implement  transactions  under the
Plan and administer the Plan in a manner that will ensure that each  transaction
by such a Participant  is exempt from  liability  under Rule 16b-3,  except that
this  provision  shall  not  limit  sales  by  such a  Participant,  and  such a
Participant  may  engage  in other  non-exempt  transactions  under  the Plan if
written notice is given to the  Participant  regarding the non-exempt  nature of
such  transaction.  The Committee  may  authorize the Company to repurchase  any
Award  or  shares  of Stock  resulting  from any  Award  in order to  prevent  a
Participant  who is subject to Section  16 of the  Exchange  Act from  incurring
liability under Section 16(b).  Unless  otherwise  specified by the Participant,
equity  securities or derivative  securities  acquired  under the Plan which are
disposed  of by a  Participant  shall be deemed to be  disposed  of in the order
acquired by the Participant.

     (e) Loan Provisions.  With the consent of the Committee, and subject at all
times to, and only to the  extent,  if any,  permitted  under and in  accordance
with,  laws  and  regulations  and  other  binding   obligations  or  provisions
applicable  to the Company,  the Company may make,  guarantee,  or arrange for a
loan or loans to a  Participant  with  respect to the  exercise of any Option or
other  payment  in  connection  with  any  Award,  including  the  payment  by a
Participant of any or all federal,  state, or local income or other taxes due in
connection with any Award. Subject to such limitations, the Committee shall have
full  authority  to  decide  whether  to make a loan or loans  hereunder  and to
determine the amount, terms, and provisions of any such loan or loans, including
the  interest  rate to be charged in respect of any such loan or loans,  whether
the loan or loans are to be with or without recourse  against the borrower,  the
terms on which the loan is to be repaid and conditions,  if any, under which the
loan or loans may be forgiven.

8.       Performance and Annual Incentive Awards.

     (a)  Performance  Conditions.  The right of a  Participant  to  exercise or
receive a grant or  settlement  of any  Award,  and the timing  thereof,  may be
subject to such performance conditions as

Amended95LTIP071698


<PAGE>



     may be specified by the  Committee.  The  Committee  may use such  business
criteria  and  other  measures  of  performance  as it may deem  appropriate  in
establishing  any  performance  conditions,  and may exercise its  discretion to
reduce or increase the amounts  payable under any Award  subject to  performance
conditions, except as limited under Sections 8(b) and 8(c) hereof in the case of
a Performance  Award or Annual  Incentive  Award  intended to qualify under Code
Section 162(m).

     (b) Performance  Awards Granted to Designated  Employees.  If the Committee
determines  that a Performance  Award to be granted to an eligible person who is
designated by the  Committee as likely to be a "covered  employee" (as such term
is used in the  regulations  under  Section  162(m)) with respect to a specified
fiscal  year  (a  "Covered  Employee")  should  qualify  as   "performance-based
compensation" for purposes of Code Section 162(m), the grant,  exercise,  and/or
settlement of such  Performance  Award shall be contingent  upon  achievement of
preestablished performance goals and other terms set forth in this Section 8(b).

     (i) Performance Goals Generally. The performance goals for such Performance
Awards shall  consist of one or more business  criteria and a targeted  level or
levels of performance with respect to each of such criteria, as specified by the
Committee  consistent  with  this  Section  8(b).  Performance  goals  shall  be
objective and shall  otherwise meet the  requirements of Code Section 162(m) and
regulations  thereunder (including Regulation 1.162-27 and successor regulations
thereto),  including  the  requirement  that the level or levels of  performance
targeted by the Committee  result in the achievement of performance  goals being
"substantially  uncertain."  The Committee may determine  that such  Performance
Awards shall be granted,  exercised,  and/or settled upon achievement of any one
performance  goal or that two or more of the performance  goals must be achieved
as a condition to the grant,  exercise,  and/or  settlement of such  Performance
Awards.  Performance goals may differ for Performance  Awards granted to any one
Participant or to different Participants.

     (ii) Business Criteria.  One or more of the following business criteria for
the Company,  on a  consolidated  basis,  and/or for specified  subsidiaries  or
business  units of the Company  (except with  respect to the annual  earnings or
earnings per share and total stockholder return criteria),  shall be used by the
Committee in establishing  performance  goals for such Performance  Awards:  (1)
annual return on equity;  (2) annual  earnings per share;  (3) changes in annual
revenues;  (4)  operating  income;  (5) total  stockholder  return;  and/or  (6)
strategic  business  criteria,  consisting  of one or more  objectives  based on
meeting specified revenue,  market  penetration,  geographic  business expansion
goals,  cost targets,  and goals relating to acquisitions or  divestitures.  The
targeted level or levels of performance  with respect to such business  criteria
may be  established  at such  levels  and in such  terms  as the  Committee  may
determine, in its discretion, including in absolute terms, as a goal relative to
performance in prior periods, or as a goal compared to the performance of one or
more comparable companies or an index covering multiple companies.

     (iii)  Performance  Period;  Timing  for  Establishing  Performance  Goals.
Achievement of performance goals in respect of such Performance  Awards shall be
measured over a performance

Amended95LTIP071698


<PAGE>



     period specified by the Committee.  Performance  goals shall be established
not later than 90 days after the beginning of any performance  period applicable
to  such  Performance  Awards,  or at such  other  date  as may be  required  or
permitted for  "performance-based  compensation" under Code Section 162(m). 

(iv) 
Settlement of Performance  Awards;  Other Terms.  Settlement of such Performance
Awards shall be in Stock, other Awards, or other property,  in the discretion of
the  Committee.  The Committee  may, in its  discretion,  reduce the amount of a
settlement  otherwise to be made in connection with such Performance Awards, but
may not exercise  discretion  to increase  any such amount  payable to a Covered
Employee in respect of a Performance  Award  subject to this Section  8(b).  The
Committee shall specify the circumstances in which such Performance Awards shall
be  paid  or  forfeited  in  the  event  of  termination  of  employment  by the
Participant or other event (including a Change of Control) prior to the end of a
performance period or settlement of Performance Awards.

     (c) Annual Incentive Awards Granted to Designated  Covered  Employees.  The
Committee may grant an Annual  Incentive Award under the Plan to a person who is
designated by the Committee as a Covered  Employee.  Such Annual Incentive Award
will be intended to qualify as "performance-based  compensation" for purposes of
Code Section 162(m), and therefore its grant, exercise,  and/or settlement shall
be contingent upon  achievement of  preestablished  performance  goals and other
terms set forth in this Section 8(c).

     (i) Grant of Annual  Incentive  Awards.  Not later than the end of the 90th
day of each fiscal  year,  or at such other date as may be required or permitted
in the case of Awards intended to be "performance-based compensation" under Code
Section 162(m),  the Committee  shall  determine the Covered  Employees who will
potentially  receive  Annual  Incentive  Awards,  and the amount(s)  potentially
payable  thereunder,  for that fiscal year.  The amount(s)  potentially  payable
shall be based upon the achievement of a performance  goal or goals based on one
or more of the  business  criteria set forth in Section  8(b)(ii)  hereof in the
given  performance  year,  as  specified by the  Committee.  The  Committee  may
designate an annual  incentive award pool as the means by which Annual Incentive
Awards will be  measured,  provided  that the  portion of such pool  potentially
payable to the  Covered  Employee  shall be  preestablished.  In all cases,  the
maximum  Annual  Incentive  Award of any  Participant  shall be  subject  to the
limitation set forth in Section 5 hereof.

     (ii) Payout of Annual Incentive Awards.  After the end of each fiscal year,
the Committee shall determine the amount,  if any, of the Annual Incentive Award
for that fiscal year  payable to each  Participant.  The  Committee  may, in its
discretion,  determine  that the amount  payable to any  Participant  as a final
Annual  Incentive Award shall be reduced from the amount of his or her potential
Annual  Incentive  Award,  including  a  determination  to make no  final  Award
whatsoever,  but may not exercise  discretion  to increase any such amount.  The
Committee  shall specify the  circumstances  in which an Annual  Incentive Award
shall be paid or  forfeited in the event of  termination  of  employment  by the
Participant or other event (including a Change of Control) prior to the end of a
fiscal year or settlement of such Annual Incentive Award.

Amended95LTIP071698


<PAGE>




     (d)  Written  Determinations.  Determinations  by the  Committee  as to the
establishment of performance goals, the amount potentially payable in respect of
Performance  Awards and Annual Incentive Awards,  the achievement of performance
goals relating to Performance Awards and Annual Incentive Awards, and the amount
of any final  Performance  Award and Annual Incentive Award shall be recorded in
writing,  except in the case of Performance Awards not intended to qualify under
Section  162(m).  Specifically,  the Committee  shall  certify in writing,  in a
manner  conforming to applicable  regulations  under  Section  162(m),  prior to
settlement  of  each  such  Award  granted  to  a  Covered  Employee,  that  the
performance  objective relating to operating profits and other material terms of
the  Award  upon  which  settlement  of the  Award  was  conditioned  have  been
satisfied.  The Committee may not delegate any  responsibility  relating to such
Performance  Awards or Annual Incentive Awards,  and the Board shall not perform
such functions at any time that the Committee is composed  solely of members who
qualify as "outside directors" under the Section 162(m) regulations.

9.       Change of Control Provisions.

     (a) Effect of Change of Control.  In the event of a "Change of Control," as
defined in this Section, the following acceleration provisions shall apply:

     (i) any outstanding  Award carrying a right to exercise which Award was not
previously  exercisable and vested,  shall become fully  exercisable and vested,
subject only to the restrictions set forth in Sections 7(d)(i) and 10(a); and

     (ii) The restrictions,  deferral of settlement,  and forfeiture  conditions
applicable to any other outstanding Award, other than an Annual Incentive Award,
granted six months or more before the date of the Change of Control  shall lapse
and such Award shall be deemed fully  vested,  subject to the  restrictions  set
forth in Sections 7(d)(i) and 10(a).

     (b) Definition of Change of Control. For purposes of the Plan, a "Change of
Control" means a transaction or event in which,  after the effective date of the
Plan, (i) the Company shall merge or consolidate with any other  corporation and
shall not be the surviving  corporation;  (ii) the Company shall transfer all or
substantially  all of its assets to any other person;  or (iii) any person shall
have  become  the  beneficial  owner  of more  than 50% of the  voting  power of
outstanding voting securities of the Company.

10.      General Provisions.

     (a)  Compliance  with  Laws  and  Obligations.  The  Company  shall  not be
obligated  to issue or deliver  Stock in  connection  with any Award or take any
other  action  under  the  Plan in a  transaction  subject  to the  registration
requirements of the Securities Act of 1933, as amended,  or any other federal or
state securities law, any requirement  under any listing  agreement  between the
Company and any national  securities  exchange or automated quotation system, or
any other law, regulation,

Amended95LTIP071698


<PAGE>



     or  contractual  obligation of the Company,  until the Company is satisfied
that such laws,  regulations,  and other  obligations  of the Company  have been
complied with in full.  Certificates  representing  shares of Stock issued under
the Plan will be subject to such stop-transfer  orders and other restrictions as
may be applicable  under such laws,  regulations,  and other  obligations of the
Company, including any requirement that a legend or legends be placed thereon.

     (b) Limitations on Transferability.  Awards and other rights under the Plan
will not be transferable by a Participant  except by will or the laws of descent
and  distribution  (or  to  a  designated   Beneficiary  in  the  event  of  the
Participant's  death),  and, if  exercisable,  shall be  exercisable  during the
lifetime of a  Participant  only by such  Participant  or his  guardian or legal
representative; provided, however, that such Awards and other rights (other than
ISOs and SARs in tandem therewith) may be transferred during the lifetime of the
Participant, for purposes of the Participant's estate planning or other purposes
consistent with the purposes of the Plan (as determined by the  Committee),  and
may be exercised by such transferees in accordance with the terms of such Award,
but only if and to the extent then consistent with the registration of the offer
and sale of Stock on Form S-8 or Form S-3 or such other registration form of the
Securities  and  Exchange  Commission  as may then be filed and  effective  with
respect to the Plan,  and  permitted by the  Committee.  Awards and other rights
under  the  Plan  may not be  pledged,  mortgaged,  hypothecated,  or  otherwise
encumbered, and shall not be subject to the claims of creditors.

     (c) No Right to Continued Employment;  Leaves of Absence.  Neither the Plan
nor any action  taken  hereunder  shall be  construed  as giving  any  employee,
consultant, subsidiary director, or other person the right to be retained in the
employ  or  service  of the  Company  or any of its  subsidiaries,  nor shall it
interfere in any way with the right of the Company or any of its subsidiaries to
terminate any  persons's  employment  or service at any time.  Unless  otherwise
specified in the applicable Award Agreement,  an approved leave of absence shall
not be  considered a  termination  of  employment  or service for purposes of an
Award under the Plan.

     (d) Taxes.  The Company and any  subsidiary  is authorized to withhold from
any Award granted or to be settled,  any delivery of Stock in connection with an
Award,  any other payment  relating to an Award, or any payroll or other payment
to a  Participant  amounts of  withholding  and other  taxes due or  potentially
payable in connection with any transaction  involving an Award, and to take such
other  action as the  Committee  may deem  advisable  to enable the  Company and
Participants  to satisfy  obligations  for the payment of withholding  taxes and
other tax  obligations  relating  to any Award.  This  authority  shall  include
authority  to  withhold  or  receive  Stock or other  property  and to make cash
payments in respect thereof in satisfaction of a Participant's tax obligations.

     (e) Changes to the Plan and Awards.  The Board may amend,  alter,  suspend,
discontinue,  or terminate the Plan or the Committee's authority to grant Awards
under the Plan without the consent of stockholders or Participants,  except that
any  amendment or  alteration  shall be subject to the approval of the Company's
stockholders at or before the next annual meeting of stockholders  for which the
record date is after the date of such Board action if such stockholder  approval
is required

Amended95LTIP071698


<PAGE>



     by any  federal  or state  law or  regulation  or the  rules  of any  stock
exchange or automated  quotation system on which the Stock may then be listed or
quoted,  and the Board may  otherwise,  in its  discretion,  determine to submit
other such  amendments or alterations to  stockholders  for approval;  provided,
however,  that, without the consent of an affected  Participant,  no such action
may materially impair the rights of such Participant under any Award theretofore
granted to him. The  Committee  may waive any  conditions  or rights  under,  or
amend, alter, suspend,  discontinue, or terminate, any Award theretofore granted
and any Award Agreement relating thereto;  provided,  however, that, without the
consent of an affected  Participant,  no such action may  materially  impair the
rights of such Participant under such Award.

     (f) No Rights to Awards;  No  Stockholder  Rights.  No Participant or other
person shall have any claim to be granted any Award under the Plan, and there is
no  obligation  for  uniformity  of  treatments  of   Participants,   employees,
consultants,  or subsidiary directors.  No Award shall confer on any Participant
any of the rights of a stockholder of the Company unless and until Stock is duly
issued or transferred  and delivered to the  Participant in accordance  with the
terms of the Award or, in the case of an Option, the Option is duly exercised.

     (g) Unfunded Status of Awards;  Creation of Trusts. The Plan is intended to
constitute an "unfunded"  plan for  incentive  and deferred  compensation.  With
respect to any  payments  not yet made to a  Participant  pursuant  to an Award,
nothing  contained in the Plan or any Award shall give any such  Participant any
rights  that are  greater  than  those of a  general  creditor  of the  Company;
provided,  however,  that the  Committee may authorize the creation of trusts or
make other  arrangements  to meet the  Company's  obligations  under the Plan to
deliver cash,  Stock,  other Awards,  or other  property  pursuant to any Award,
which  trusts or other  arrangements  shall be  consistent  with the  "unfunded"
status of the Plan unless the Committee otherwise determines with the consent of
each affected Participant.

     (h)  Nonexclusivity  of the Plan.  Neither the  adoption of the Plan by the
Board nor its submission to the  stockholders  of the Company for approval shall
be construed as creating any limitations on the power of the Board to adopt such
other  compensatory  arrangements as it may deem desirable,  including,  without
limitation,  the  granting  of awards  otherwise  than under the Plan,  and such
arrangements may be either applicable generally or only in specific cases.

     (i) No Fractional  Shares. No fractional shares of Stock shall be issued or
delivered  pursuant  to the Plan or any Award.  The  Committee  shall  determine
whether cash, other Awards, or other property shall be issued or paid in lieu of
such fractional  shares or whether such fractional  shares or any rights thereto
shall be forfeited or otherwise eliminated.

     (j) Compliance  with Code Section  162(m).  It is the intent of the Company
that Options,  SARs, and other Awards  designated as Awards to Covered Employees
subject to Section 8 shall constitute "qualified performance-based compensation"
within the meaning of Code Section 162(m) and regulations  thereunder (including
Proposed Regulation 1.162-27). Accordingly, the terms of

Amended95LTIP071698


<PAGE>


     Sections 8(b), (c), and (d),  including the definitions of Covered Employee
and other terms used therein,  shall be interpreted in a manner  consistent with
Code Section 162(m) and regulations thereunder.  The foregoing  notwithstanding,
because  the  Committee  cannot   determine  with  certainty   whether  a  given
Participant  will be a Covered  Employee  with respect to a fiscal year that has
not yet been completed, the term Covered Employee as used herein shall mean only
a person designated by the Committee, at the time of grant of Performance Awards
or an Annual Incentive Award, as likely to be a Covered Employee with respect to
a specified fiscal year. If any provision of the Plan or any agreement  relating
to a Performance  Award or Annual Incentive Award that is designated as intended
to comply with Code Section 162(m) does not comply or is  inconsistent  with the
requirements  of Code Section 162(m) or regulations  thereunder,  such provision
shall be construed or deemed amended to the extent  necessary to conform to such
requirements,  and no provision  shall be deemed to confer upon the Committee or
any other person  discretion  to increase the amount of  compensation  otherwise
payable in  connection  with any such Award upon  attainment  of the  applicable
performance objectives.

     (k) Governing Law. The validity,  construction, and effect of the Plan, any
rules and regulations under the Plan, and any Award Agreement will be determined
in accordance with the Nevada General  Corporation Law and other laws (including
those  governing  contracts)  of the State of Nevada,  without  giving effect to
principles of conflicts of laws, and applicable federal law.

     (l) Effective Date,  Stockholder Approval,  and Plan Termination.  The Plan
became effective May 16, 1995, upon its approval by stockholders of the Company.
The 1998 amendment and  restatement of the Plan shall be subject to the approval
of the  stockholders of the Company by the vote required by Section  78.320.1(b)
of the Nevada  Revised  Statutes  at the 1998  Annual  Meeting of  Stockholders.
Unless  earlier  terminated by action of the Board of  Directors,  the Plan will
remain in effect  until such time as no Stock  remains  available  for  delivery
under the Plan and the Company has no further  rights or  obligations  under the
Plan with respect to outstanding Awards under the Plan.

                                           SIERRA HEALTH SERVICES, INC.
                                      1995 NON-EMPLOYEE DIRECTORS' STOCK PLAN
                                   As Amended and Restated through May 18, 1998

     1. Purpose.  The purpose of this 1995  Non-Employee  Directors'  Stock Plan
(the "Plan") of Sierra Health  Services,  Inc. (the "Company") is to advance the
interests  of the Company and its  stockholders  by providing a means to attract
and retain highly  qualified  persons to serve as non-employee  directors of the
Company and to promote  ownership  by such  directors  of a greater  proprietary
interest in the Company, thereby aligning such directors' interests more closely
with the interests of stockholders of the Company.

     2.  Definitions.  In addition to terms defined  elsewhere in the Plan,  the
following terms are defined as set forth below:

     (a) "Code" means the Internal Revenue Code of 1986, as amended from time to
time. References to any provision of the Code include regulations thereunder and
successor provisions and regulations thereto.

     (b) "Change of Control"  means a transaction  or event in which,  after the
effective date of the Plan, (i) the Company shall merge or consolidate  with any
other corporation and shall not be the surviving  corporation;  (ii) the Company
shall transfer all or  substantially  all of its assets to any other person;  or
(iii) any person shall have become the beneficial  owner of more than 50% of the
voting power of outstanding voting securities of the Company.

     (c) "Deferred Stock" means the credits to a Participant's  deferral account
under  Section 7, each of which  represents  the right to  receive  one share of
Stock upon settlement of the deferral account.  Deferral accounts,  and Deferred
Stock  credited  thereto,  are maintained  solely as bookkeeping  entries by the
Company evidencing unfunded obligations of the Company.

     (d) "Exchange Act" means the  Securities  Exchange Act of 1934, as amended.
References  to any provision of the Exchange Act include  rules  thereunder  and
successor provisions and rules thereto.

     (e) "Fair Market Value" of Stock means,  as of any given date,  the closing
sale price of a share of Stock  reported in the table  entitled  "New York Stock
Exchange  Composite  Transactions"  contained in The Wall Street  Journal (or an
equivalent  successor  table)  for such  date or, if no such  closing  price was
reported for such date,  for the most recent  trading day prior to such date for
which such closing price was reported.

     (f) "Option"  means the right,  granted to a director  under  Section 6, to
purchase a specified

Amended95NED071698


<PAGE>



     number of shares of Stock at the specified  exercise  price for a specified
period of time under the Plan. All Options will be non-qualified stock options.

     (g) "Participant"  means a director of the Company who is granted an Option
or who receives fees in the form of Stock or defers fees in the form of Deferred
Stock under the Plan.

     (h) "Retirement"  means a Participant  ceasing to serve as a director at or
after reaching age 75, other than due to death.

     (i) "Stock"  means the Common  Stock,  $.005 par value,  of the Company and
such other  securities as may be substituted for Stock or such other  securities
pursuant to Section 8.

     3. Shares  Available  Under the Plan.  Subject to adjustment as provided in
Section  8, the  total  number of shares of Stock  reserved  and  available  for
issuance  under the Plan is 90,000.  Such shares may be authorized  but unissued
shares, treasury shares, or shares acquired in the market for the account of the
Participant.  For  purposes  of the  Plan,  shares  that may be  purchased  upon
exercise of an Option or delivered in settlement  of Deferred  Stock will not be
considered to be available  after such Option has been granted or Deferred Stock
credited,  except for  purposes of issuance  in  connection  with such Option or
Deferred  Stock;  provided,  however,  that, if an Option expires for any reason
without having been  exercised in full,  the shares  subject to the  unexercised
portion of such Option will again be available for issuance under the Plan.

     4.  Administration  of the Plan. The Plan will be administered by the Board
of  Directors of the Company;  provided,  however,  that any action by the Board
relating to the Plan will be taken only if, in  addition  to any other  required
vote,  such  action is  approved  by the  affirmative  vote of a majority of the
directors who are not then eligible to participate in the Plan.

     5.  Eligibility.  Each director of the Company who, on any date on which an
Option is to be  granted  under  Section 6 or on which fees are to be paid which
could be received in the form of Stock or deferred in the form of Deferred Stock
under  Section 7, is not an  employee of the  Company or any  subsidiary  of the
Company will be eligible,  at such date, to be granted an Option under Section 6
or receive fees in the form of Stock or defer fees in the form of Deferred Stock
under Section 7. No person other than those  specified in this Section 5 will be
eligible to participate in the Plan.

     6.  Options.  An Option to  purchase  7,500  shares  of Stock,  subject  to
adjustment  as  provided  in Section 8, will be  automatically  granted (i) to a
person who is first  elected or  appointed  to serve as a member of the Board of
Directors of the Company  after the  effective  date of the Plan, on the date of
such  election  or  appointment,  if such  director is eligible to be granted an
Option at that date,  and (ii) to each member of the Board of  Directors  of the
Company on January 20, 1996 and on each January 20  thereafter  if such director
is  eligible  to be  granted an Option at that date and has not  otherwise  been
granted an Option under this Section 6 during the six-month  period prior to and
including the date the Option would otherwise be granted hereunder. Options will
be subject to the

Amended95NED071698


<PAGE>



following terms and conditions:

     (a) Exercise Price. The exercise price per share of Stock  purchasable upon
exercise of an Option will be equal to 100% of the Fair Market Value of Stock on
the date of grant of the Option.

     (b) Option Expiration. A Participant's Option will expire at the earlier of
(i) ten  years  after  the  date of  grant,  (ii) one  year  after  the date the
Participant  ceases  to  serve  as a  director  of the  Company  due  to  death,
disability,  or Retirement,  or (iii) six months after the Participant ceases to
serve as a director of the Company for any reason  other than death,  disability
or Retirement;  provided,  however, that, if the Participant dies during the one
year after  ceasing to serve as a director due to  disability  or  Retirement or
during the six months  after  ceasing to serve as a director  for reasons  other
than disability or Retirement, the expiration shall be delayed until the earlier
of one year after the  Participant's  death or ten years after the date of grant
of the Option.

     (c) Exercisability.  Each Option will become cumulatively exercisable as to
20% of the shares of Stock  subject to such  Option on each  anniversary  of the
date of grant; provided,  however, that a Participant's Option, to the extent it
has not previously become  exercisable,  will become immediately  exercisable in
full (i) at the time the Participant  ceases to serve as a director due to death
or  disability,  (ii) at the date six  months  prior  to the  expiration  of the
Participant=s  term of office as a director  during  which term the  Participant
reaches  age 75, if the  Participant  continues  to serve as a director  at such
vesting  date,  or (iii),  in the case of an Option  granted  six months or more
prior to a Change of Control, upon such Change of Control; and provided further,
that a Participant's  Option may be exercised  after the  Participant  ceases to
serve as a director  only to the extent  that the Option was  exercisable  at or
before the date he or she ceased to be a director.

     (d) Method of Exercise.  A Participant may exercise an Option,  in whole or
in part,  at such  time as it is  exercisable  and prior to its  expiration,  by
giving  written  notice of exercise to the Secretary of the Company,  specifying
the Option to be  exercised  and the number of shares of Stock to be  purchased,
and  paying  in full the  exercise  price in cash  (including  by  check)  or by
surrender of shares of Stock already owned by the Participant (except for shares
acquired  from the Company by exercise of an option less than six months  before
the date of surrender)  having a Fair Market Value at the time of exercise equal
to the exercise price, or by a combination of cash and Stock.

     7. Receipt of Stock or Deferred Stock in lieu of Fees. Each director of the
Company  may,  in lieu of receipt of fees in his or her  capacity  as a director
(including  annual retainer fees for service on the Board, fees for service on a
Board  committee,  fees for service as chairman  of a Board  committee,  and any
other fees paid to directors) in cash, receive such fees in the form of Stock or
defer receipt of such fees in the form of Deferred Stock in accordance with this
Section 7;  provided,  however,  that such  director  is eligible to do so under
Section 5 at the date any such fee is otherwise payable.

     (a)  Elections.  Each  director  who  elects  to  receive  fees for a given
calendar year in the form of

Amended95NED071698


<PAGE>



     Stock or to defer  fees in the form of  Deferred  Stock  for such year must
file an  irrevocable  written  election  with the Secretary of the Company on or
before such filing  deadline as may be  specified  by the  Secretary;  provided,
however,  that any newly elected or appointed  director may file an election not
later than 30 days after the date such person first became a director,  in which
case such election shall apply to fees payable for services  performed after the
date of such filing.  An election by a director shall be deemed to be continuing
and therefore applicable to subsequent Plan years unless the director revokes or
changes  such  election by filing a new  election  form by the due date for such
form specified in this Section 7(a). The election must specify the following:

     (i) A percentage of fees to be received in the form of Stock or deferred in
the form of Deferred Stock under the Plan; and

     (ii) In the  case  of a  deferral,  the  period  or  periods  during  which
settlement of Deferred  Stock will be deferred  (subject to such  limitations as
may be specified by counsel to the Company).

     If required in order that transactions under this Section 7 shall be exempt
under Rule  16b-3(d),  elections  under this  Section 7 shall be reviewed by the
Board of Directors and  resulting  transactions  approved,  for purposes of Rule
16b-3 under the Exchange  Act, at the Board's  first meeting at or following the
date by which the  election  has  become  irrevocable;  failure  of the Board to
approve transactions resulting from elections shall not, however, invalidate the
elections or preclude such transactions.

     (b)  Payment  of Fees in the Form of Stock.  At any date on which  fees are
payable to a  Participant  who has  elected to receive  such fees in the form of
Stock, the Company will issue to such Participant,  or to an account  maintained
by a third party and designated by such Participant, a number of shares of Stock
having an  aggregate  Fair  Market  Value at that date equal to the fees,  or as
nearly as possible  equal to the fees (but in no event  greater  than the fees),
that would have been payable at such date but for the Participant's  election to
receive  Stock in lieu  thereof.  If the Stock is to be  credited  to an account
maintained by the Participant and to the extent reasonably  practicable  without
requiring  the actual  issuance of  fractional  shares,  the Company shall cause
fractional  shares to be credited to the  Participant's  account.  If fractional
shares are not so credited,  any part of the Participant's  fees not paid in the
form of whole shares of Stock will be payable in cash to the Participant (either
separately or included in a subsequent  payment of fees,  including a subsequent
payment of fees subject to an election under this Section 7).

     (c)  Deferral  of Fees in the Form of  Deferred  Stock.  The  Company  will
establish a deferral  account for each  Participant  who elects to defer fees in
the form of Deferred  Stock under this  Section 7. At any date on which fees are
payable to a  Participant  who has elected to defer fees in the form of Deferred
Stock, the Company will credit such Participant's deferral account with a number
of shares of  Deferred  Stock  equal to the number of shares of Stock  having an
aggregate Fair Market Value at that date equal to the fees that otherwise  would
have been  payable  at such  date but for the  Participant's  election  to defer
receipt of such fees in the form of Deferred Stock. The amount of

<PAGE>



     Deferred Stock so credited shall include fractional shares calculated to at
least three decimal places.

     (d)  Crediting  of Dividend  Equivalents.  Whenever  dividends  are paid or
distributions  made with respect to Stock,  a Participant to whom Deferred Stock
is then  credited in a deferral  account  shall be  entitled  to be receive,  as
dividend  equivalents,  an amount  equal in value to the amount of the  dividend
paid or property distributed on a single share of Stock multiplied by the number
of shares of Deferred Stock (including any fractional  share) credited to his or
her deferral  account as of the record date for such  dividend or  distribution.
Such  dividend  equivalents  shall be  credited  to the  Participant's  deferral
account as a number of shares of  Deferred  Stock  determined  by  dividing  the
aggregate value of such dividend equivalents by the Fair Market Value of a share
of Stock at the payment date of the dividend or distribution.

     (e) Settlement of Deferred Stock. The Company will settle the Participant's
deferral  account by delivering to the Participant (or his or her beneficiary) a
number of shares of Stock equal to the number of whole shares of Deferred  Stock
then  credited to his or her  deferral  account  (or a specified  portion in the
event of any partial  settlement),  together with cash in lieu of any fractional
share  remaining  at a time that less than one whole share of Deferred  Stock is
credited to such deferral account.  Such settlement shall be made at the time or
times specified in the  Participant's  election filed in accordance with Section
7(a);  provided,  however,  that a Participant  may further defer  settlement of
Deferred Stock if counsel to the Company  determines that such further  deferral
likely  would  be  effective  under  applicable  federal  income  tax  laws  and
regulations.

     (f) Designation of Beneficiary.  Each Participant may designate one or more
beneficiaries  to  receive  the  amounts  distributable  from the  Participant's
deferral  account under the Plan in the event of such  Participant's  death, and
the  terms of any such  distribution,  on forms  provided  by the  Company.  The
Company may rely upon the beneficiary  designation last filed in accordance with
this Section 7(f).

     (g) Nonforfeitability. The interest of each Participant in any fees paid in
the form of Stock or Deferred Stock (and any deferral account relating  thereto)
at all times will be nonforfeitable.

8.       Adjustment Provisions.

     (a) Corporate  Transactions and Events. In the event any  recapitalization,
reorganization,   merger,  consolidation,   spin-off,  combination,  repurchase,
exchange of shares or other  securities  of the Company,  stock split or reverse
split,  stock  dividend,  other  special,  large,  and  non-recurring  dividend,
liquidation,  dissolution,  or  other  similar  corporate  transaction  or event
affects the Stock such that an  adjustment  is  appropriate  in order to prevent
dilution or enlargement  of each  Participant's  rights under the Plan,  then an
adjustment shall be made, in a manner that is proportionate to the change to the
Stock and  otherwise  equitable,  in (i) the  number and kind of shares of Stock
remaining  available  for issuance  under the Plan,  (ii) the number and kind of
shares of Stock to be subject to each automatic grant of an Option under Section
6, (iii) the number and kind of

Amended95NED071698


<PAGE>



     shares of Stock issuable upon exercise of outstanding  Options,  and/or the
exercise  price per share thereof  (provided  that no fractional  shares will be
issued  upon  exercise  of any  Option),  (iv) the kind of shares of Stock to be
issued in lieu of fees under Section 7, and (v) the number and kind of shares of
Stock to be issued  upon  settlement  of  Deferred  Stock  under  Section 7. The
foregoing notwithstanding, no adjustment may be made hereunder except as will be
necessary to maintain the  proportionate  interest of the Participant  under the
Plan and to preserve,  without exceeding,  the value of outstanding  Options and
potential grants of Options.

     (b) Insufficient Number of Shares. If at any date an insufficient number of
shares of Stock are available  under the Plan for the automatic grant of Options
or the  receipt of fees in the form of Stock or  deferral of fees in the form of
Deferred  Stock  at that  date,  Options  will  first be  automatically  granted
proportionately  to each  eligible  director,  to the  extent  shares  are  then
available  (provided  that no fractional  shares will be issued upon exercise of
any Option) and  otherwise as provided  under Section 6, and then, if any shares
remain  available,  fees shall be paid in the form of Stock or  deferred  in the
form  of  Deferred  Stock  proportionately  among  directors  then  eligible  to
participate  to the extent  shares are then  available and otherwise as provided
under Section 7.

     9. Changes to the Plan. The Board of Directors may amend,  alter,  suspend,
discontinue,  or terminate the Plan or authority to grant Options or pay fees in
the form of Stock or  Deferred  Stock  under the Plan  without  the  consent  of
stockholders  or  Participants,  except that any amendment or alteration will be
subject to the  approval  of the  Company's  stockholders  at or before the next
annual  meeting of  stockholders  for which the record date is after the date of
such Board  action if such  stockholder  approval  is required by any federal or
state  law or  regulation  or the  rules  of any  stock  exchange  or  automated
quotation  system,  and the Board may  otherwise  determine to submit other such
amendments or alterations to stockholders for approval; provided, however, that,
without the consent of an affected  Participant,  no such action may  materially
impair the rights of such  Participant  with respect to any  previously  granted
Option or any previous  payment of fees in the form of Stock or deferral of fees
in the form of Deferred Stock.

10.      General Provisions.

     (a) Agreements. Options, Deferred Stock, and any other right under the Plan
may be evidenced by  agreements or other  documents  executed by the Company and
the  Participant  incorporating  the terms and conditions set forth in the Plan,
together with such other terms and conditions not inconsistent with the Plan, as
the Board of Directors may from time to time approve.

     (b) Compliance with Laws and Obligations. The Company will not be obligated
to issue or deliver shares of Stock in connection with any Option, in payment of
any directors' fees, or in settlement of Deferred Stock in a transaction subject
to the registration  requirements of the Securities Act of 1933, as amended,  or
any other federal or state  securities  law, any  requirement  under any listing
agreement  between  the Company and any stock  exchange or  automated  quotation
system, or any other law, regulation,  or contractual obligation of the Company,
until  the  Company  is  satisfied  that  such  laws,  regulations,   and  other
obligations  of the  Company  have  been  complied  with in  full.  Certificates
representing  shares of Stock  issued  under the Plan  will be  subject  to such
stop-transfer  orders and other  restrictions  as may be  applicable  under such
laws,  regulations,   and  other  obligations  of  the  Company,  including  any
requirement that a legend or legends be placed thereon.

     (c) Limitations on Transferability.  Options, Deferred Stock, and any other
right under the Plan will not be transferable by a Participant except by will or
the laws of descent and  distribution  (or to a  designated  beneficiary  in the
event of a Participant's  death), and will be exercisable during the lifetime of
the  Participant  only by  such  Participant  or his or her  guardian  or  legal
representative;  provided,  however, that Options and Deferred Stock (and rights
relating   thereto)  may  be   transferred  to  one  or  more  trusts  or  other
beneficiaries  during  the  lifetime  of the  Participant  for  purposes  of the
Participant's  estate  planning,  and may be  exercised by such  transferees  in
accordance with the terms thereof, but only if and to the extent then consistent
with the  registration  of the offer and sale of shares of Stock related thereto
on Form S-8, Form S-3, or such other  registration  form of the  Securities  and
Exchange Commission as may then be filed and effective with respect to the Plan.
Options,  Deferred  Stock,  and other  rights under the Plan may not be pledged,
mortgaged,  hypothecated,  or otherwise encumbered,  and shall not be subject to
the claims of creditors of any Participant.

(d)      Compliance with Rule 16b-3.

     (i) Compliance Generally. With respect to a Participant who is then subject
to the reporting requirements of Section 16(a) of the Exchange Act in respect of
the  Company,  the  Board  shall  implement  transactions  under  the  Plan  and
administer the Plan in a manner that will ensure that each transaction by such a
Participant  is exempt  from  liability  under Rule  16b-3,  except  that such a
Participant  may be permitted to engage in a  non-exempt  transaction  under the
Plan if written  notice is given to the  Participant  regarding  the  non-exempt
nature of such  transaction.  The Board may  authorize the Company to repurchase
any  Award or  shares of Stock  resulting  from any Award in order to  prevent a
Participant who is subject to Section 16 of the Exchange Act from incurring

Amended95NED071698


<PAGE>



     liability  under  Section  16(b).   Unless   otherwise   specified  by  the
Participant,  equity securities or derivative securities acquired under the Plan
which are disposed of by a Participant  shall be deemed to be disposed of in the
order acquired by the Participant.


Amended95NED071698


<PAGE>


     (ii) Six-Month Holding Period. Unless a Participant could otherwise dispose
of equity securities (including  derivative  securities) acquired under the Plan
without  incurring  liability  under Section  16(b) of the Exchange Act,  equity
securities  acquired  under  the Plan  must be held for a period  of six  months
following the date of such  acquisition,  provided that this condition  shall be
satisfied  with respect to a derivative  security if at least six months  elapse
from  the  date  of  acquisition  of the  derivative  security  to the  date  of
disposition of the derivative  security (other than upon exercise or conversion)
or its underlying equity security.

     (e) Continued Service as an Employee.  If a Participant ceases serving as a
director of the Company and, immediately thereafter,  is employed by the Company
or any subsidiary of the Company, then, solely for purposes of Sections 6(b) and
(c), such Participant will not be deemed to have ceased service as a director at
that time and his or her continued  employment by the Company or any  subsidiary
will be deemed to be continued service as a director.

     (f) NO RIGHT TO CONTINUE AS A DIRECTOR.  Nothing  contained  in the Plan or
any agreement  hereunder will confer upon any  Participant any right to continue
to serve as a director of the Company.

     (g) No Stockholder  Rights Conferred.  Nothing contained in the Plan or any
agreement  hereunder will confer upon any  Participant  (or any person or entity
claiming rights by or through a Participant)  any rights of a stockholder of the
Company unless and until shares of Stock are in fact issued to such  Participant
(or person) or his or her account maintained by a third party or, in the case an
Option, such Option is validly exercised in accordance with Section 6.

     (h)  Nonexclusivity  of the Plan.  Neither the  adoption of the Plan by the
Board of Directors  nor its  submission to the  stockholders  of the Company for
approval  shall be  construed as creating  any  limitations  on the power of the
Board to adopt such other compensatory arrangements for directors as it may deem
desirable.

     (i) Governing Law. The validity,  construction,  and effect of the Plan and
any agreement hereunder will be determined in accordance with the Nevada General
Corporation  Law and other laws  (including  those  governing  contracts) of the
State of Nevada,  without  giving effect to principles of conflicts of laws, and
applicable federal law.

     11.  Stockholder  Approval  Effective Date, and Plan Termination.  The Plan
became effective May 16, 1995, upon its approval by stockholders of the Company.
Unless  earlier  terminated by action of the Board of  Directors,  the Plan will
remain in effect  until  such time as no shares of Stock  remain  available  for
issuance under the Plan and the Company and Participants  have no further rights
or obligations under the Plan.
