              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, 1996 and 1995. In the
          opinion  of   management,   the   accompanying   unaudited   condensed
          consolidated financial statements reflect all adjustments,  consisting
          only  of  normal   recurring   adjustments,   necessary   for  a  fair
          presentation  of  the  financial   results  for  the  interim  periods
          presented.

2.         In the  second  quarter  of 1997,  the line of credit  agreement  the
           ("Credit  Agreement"),  among Sierra,  Bank of America National Trust
           and Savings Association as Agent, and other lenders,  was amended and
           increased to $100 million.  In March 1997, the Company borrowed $17.0
           million  on its  line  of  credit  for  general  corporate  purposes.
           Currently the interest  rate is 6.3%.  The amount owed on the line of
           credit is included in long-term  debt at June 30, 1997. The remaining
           line of  credit  may be  used  for  additional  working  capital,  if
           necessary.

3.         During the first quarter of 1997, the Company recorded $11.0 million,
           $8.4 million after taxes,  for certain  estimated  costs and expenses
           incurred  in  association  with a  merger  agreement  with  Physician
           Corporation  of America  ("PCA"),  such  agreement was  terminated on
           March 18, 1997, as disclosed in the Company's  Annual Report filed on
           Form 10-K for the fiscal year ended December 31, 1996.

4.        During 1997 the Financial  Accounting  Standards Board ("FASB") issued
          the following  statements of financial  accounting  standards ("FAS"):
          FAS No.  128,  "Earnings  per  Share",  FAS No.  129,  "Disclosure  of
          Information  about  Capital   Structure",   FAS  No.  130,  "Reporting
          Comprehensive  Income", and FAS No. 131, "Disclosure About Segments of
          an Enterprise and Related Information".

           FAS No. 128 and FAS No. 129 are  effective  for periods  ending after
           December  15,  1997,  and  establish   standards  for  computing  and
           presenting earnings per share ("EPS"), and for disclosing information
           about  an  entity's  capital  structure,   respectively.   Management
           believes that these  standards will not have a significant  impact on
           its EPS or financial  statement  disclosure.  FAS No. 130 and FAS No.
           131 are effective for periods  beginning after December 15, 1997. FAS
           No. 130 requires  companies to classify items of other  comprehensive
           income by their nature in a financial statement.  Management does not
           believe this statement  will have a material  impact on the Company's
           financial  statements.  FAS No. 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.

5.         In the  second  quarter of 1997,  the  Company's  Board of  Directors
           authorized a stock repurchase  program of up to one million shares of
           the Company's outstanding stock. As of June 30, 1997, the Company had
           repurchased 184,300 shares for $5.5 million.

6.         Amounts  in  the  accompanying   Condensed   Consolidated   Financial
           Statements  for the three  months and six months  ended June 30, 1996
           have  been   reclassified   to  conform   with  the  current   period
           presentation.

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  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  should be  considered  in  connection  with  certain  cautionary
statements  contained in the Company's  Current  Report on Form 8-K filing dated
March 28,  1997.  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,  1997,  compared to three
months ended June 30, 1996.

The Company's total operating  revenues for the three months ended June 30, 1997
increased  24.7% to $176.3 from $141.4  million for the three  months ended June
30, 1996. The increase was primarily due to medical premium revenue increases of
$31.8 million,  or 34.1%, from the Company's HMO and managed indemnity insurance
subsidiaries.  Such additional premium revenue resulted principally from a 30.3%
increase  in  member  months  (the  number  of  months  of each  period  that an
individual is enrolled in a plan). The Company's HMO and insurance subsidiaries'
premium rates increased  approximately  3.8% primarily due to an increase in its
capitation  rate for its  Medicare  members as  established  by the Health  Care
Financing Administration ("HCFA"). The increase was due in part to the Company's
participation  in HCFA's social HMO program.  The Company realized 1% to 3% rate
increases for its existing HMO  subsidiaries'  commercial groups and the managed
indemnity  subsidiary.  However,  these  increases  were offset in part by lower
rates  realized by MedOne  Health  Plan,  an HMO  acquired on December 31, 1996.
Specialty product revenue increased $3.7 million, or 11.2%, for the three months
ended June 30, 1997 compared to the same  three-month  period in the prior year.
The  increase  was due to  specialty  product  revenue  growth  in the  workers'
compensation  insurance market of $1.9 million and an increase in administrative
services of $1.8 million due primarily to the acquisition of Prime Health,  Inc.
at the end of 1996. Some of this increase in administrative services revenue may
be offset  in the  future  by the loss of a  portion  of the  State of  Nevada's
self-insured  business.  Professional  fee revenue  decreased  slightly from the
comparable period in the prior year.  Investment and other revenue decreased due
to certain investment gains recognized in the second quarter of 1996.

Total medical expenses  increased $25.9 million over the same three-month period
last year. This 34.2% increase resulted  primarily from the consolidated  member
month growth discussed  previously.  Medical expenses as a percentage of medical
premiums and  professional  fees ("Medical Loss Ratio")  increased from 75.0% to
76.7% due primarily to member growth and expansion in areas with higher  medical
expenses, such as northern Nevada and Texas. In addition, MedOne Health Plan has
a higher  Medical Loss Ratio,  which further  contributed to the increase in the
Company's overall Medical Loss Ratio.  Specialty product expenses increased $2.7
million,  or 8.0%,  due  primarily to the 11.2%  increase in  specialty  product
revenue discussed previously. Specialty product revenue and expense is primarily
related to the workers' compensation insurance business.

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

Results of  Operations,  three  months  ended June 30,  1997,  compared to three
months ended June 30, 1996 (continued).

The combined ratio for the workers'  compensation  insurance business was 101.7%
compared to 105.1% for the  comparable  prior year  period.  The  reduction  was
primarily  due to a 4.7  percentage  point  decrease in the loss ratio which was
partially  offset by a 1.3  percentage  point  increase  in the  expense  ratio.
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  compared to net favorable loss development
of $3.1  million  for the  comparable  prior  year  period.  The losses and loss
adjustment  expense  ratio for the three months ended June 30, 1997 reflects the
Company's  current  projection of the ultimate costs of claims  occurring in the
current as well as prior accident years.  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 $5.7 million,  or
33.2%, compared to the second quarter of 1996. As a percentage of revenues,  G&A
costs for the second  quarter of 1997  increased  to 13.1% from 12.2% during the
comparable  period in 1996.  Of the $5.7 million  increase in G&A,  $2.2 million
consisted of increased  compensation expense resulting primarily from additional
employees supporting expanded services. Broker, third-party administration,  and
premium tax  expenses  increased  approximately  $2.1  million due to  increased
membership.  Amortization  increased  approximately  $400,000. The remaining G&A
increase  is  due  to  additional  expenses  in  several  areas  including  data
processing  maintenance.  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,  1997,  the  Company's  ten
largest  commercial HMO employer groups were, in the aggregate,  responsible for
less than 15% of its  total  revenues.  Although  none of such  employer  groups
accounted for more than 3% 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 over the same period
in the prior year  primarily  due to the almost  $600,000  benefit for  minority
interests  recorded  in  1996,  offset  in part by an  increase  in  capitalized
interest related to various construction projects in 1997. In November 1996, the
Company  acquired  complete  ownership of a Texas HMO in which it had previously
held a 50%  interest.  That HMO began  business  in March  1995 and  experienced
losses in both three-month  periods. In the prior period,  these losses resulted
in a benefit from minority interests.

The decrease in the effective tax rate for the second quarter of 1997 from 25.4%
to 24.0% resulted from the Company's investment in tax-preferred investments and
the change in the deferred tax  valuation  allowance,  which is due primarily to
the ability to use a portion of net operating loss carryovers.

Net income for the three months ended June 30, 1997 increased  $400,000 to $10.6
million  over the  comparable  prior year  period.  The increase in earnings was
primarily due to increased  operating  revenues  offset by a higher Medical Loss
Ratio and increased G&A expenses as a percentage  of revenues.  In addition,  as
discussed previously,  the Company recorded  approximately  $600,000 in minority
interest in the prior year  period.  Excluding  the effects of the prior  period
benefit  related to minority  interests  income  before  income taxes  increased
approximately $800,000.

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

Results of  Operations,  six months ended June 30, 1997,  compared to six months
ended June 30, 1996.

The Company's  total  operating  revenues for the six months ended June 30, 1997
increased 25.1% to $346.9 million, from $277.4 million, for the six months ended
June 30,  1996.  The  increase  was  primarily  due to medical  premium  revenue
increases of approximately  $63.6 million,  or 34.5%, from the Company's HMO and
managed  indemnity  insurance  subsidiaries.  Such  additional  premium  revenue
resulted  principally from a 31.2% increase in member months.  The Company's HMO
and insurance  subsidiaries' premium rates increased approximately 3.4% overall,
primarily due to an increase in its capitation rate for its Medicare  members as
established by HCFA. The increase was due in part to the Company's participation
in HCFA's social HMO program.  The Company  realized 1% to 3% rate increases for
its  existing  HMO  subsidiaries'  commercial  groups and the managed  indemnity
subsidiary. However, these increases were offset in part by lower rates realized
by MedOne Health Plan, an HMO acquired on December 31, 1996.  Specialty  product
revenue increased $7.5 million,  or 11.7%, in the six months ended June 30, 1997
compared to the same six-month period in the prior year. The increase was due to
specialty  product  revenue growth of $4.3 million in the workers'  compensation
insurance market and an increase in administrative  services of $3.2 million due
primarily to the  acquisition of Prime Health,  Inc. at the end of 1996. Some of
this increase in administrative  services revenue may be offset in the future by
the  loss  of  a  portion  of  the  State  of  Nevada's  self-insured  business.
Professional fee revenue  decreased  slightly from the comparable  period in the
prior year. Investment and other revenue decreased $1.3 million, or 9.4%, due to
certain investment gains recognized in the first six months of 1996.

Total medical expenses increased by $51.7 million over the same six-month period
last year. This 34.5% increase resulted  primarily from the consolidated  member
month growth discussed  previously.  The Medical Loss Ratio increased from 75.2%
to 76.7% due  primarily  to member  growth and  expansion  in areas with  higher
medical expenses, such as northern Nevada and Texas. In addition,  MedOne Health
Plan has a higher Medical Loss Ratio, which further  contributed to the increase
in  the  Company's  overall  Medical  Loss  Ratio.  Specialty  product  expenses
increased  $6.8  million,  or 10.6%,  due  primarily  to the 11.7%  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 103.1%
compared to 104.9% for the  comparable  prior year  period.  The  reduction  was
primarily due to a 1.1 percentage  point decrease in the loss ratio along with a
0.7 percentage  point decrease in the expense ratio.  Compared to the prior year
period,  incurred losses for the current  accident year were reduced as a result
of the Company's ability to overlay and implement managed care techniques to the
workers'  compensation  claims. In addition,  the Company had net favorable loss
development totalling $4.4 million compared to net favorable loss development of
$7.1 million for the  comparable  prior year period.  There can be no assurances
that  favorable  development,  or the  magnitude  thereof,  will continue in the
future.  The losses and loss  adjustment  expense ratio for the six months ended
June 30, 1997 reflects the Company's current projection of the ultimate costs of
claims  occurring  in  the  current  as  well  as  prior  accident  years.  Such
projections  are  subject  to change and any change  would be  reflected  in the
income statement.

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

Results of  Operations,  six months ended June 30, 1997,  compared to six months
ended June 30, 1996 (continued).

G&A costs increased $10.6 million, or 30.7%, compared to the first six months of
1996.  As a percentage  of revenues,  G&A costs for the first six months of 1997
increased to 13.0% from 12.4% during the comparable period in 1996. Of the $10.6
million  increase  in  G&A,  $3.4  million  consisted  of  compensation  expense
resulting  primarily from additional  employees  supporting  expanded  services.
Broker,   third-party   administration,   and  premium  tax  expenses  increased
approximately $4.6 million due to increased membership.  Amortization  increased
$700,000.  The remaining  G&A increase is due to additional  expenses in several
areas  including data processing  maintenance.  The Company markets its products
primarily  to  employer  groups and labor  unions  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,  1997,  the  Company's  ten largest
commercial HMO employer groups were, in the aggregate, responsible for less than
15% of its total revenues.  Although none of such employer groups  accounted for
more than 3% 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.

In the first quarter of 1997, the Company recorded  estimated  expenses of $11.0
million,  $8.4 million after tax, for  merger-related  costs. On March 18, 1997,
the Company  announced  it had  terminated  its merger  agreement  with 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.  Although the Company  believes the PCA
lawsuit is without merit, there can be no assurance as to the outcome of the PCA
lawsuit.  The  Company  has  filed a motion  in the  District  Court  seeking  a
dismissal  of the PCA lawsuit.  The Company has also  initiated a lawsuit in the
Court of  Chancery of the State of Delaware  seeking a  declaratory  judgment as
well as 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  or that PCA will have  sufficient  funds to pay any
damages that the Company may be awarded.

Interest  expense  and  other  increased  approximately  $1.0  million  from the
comparable  prior year period  primarily due to the almost $1.0 million  benefit
for minority  interests recorded in 1996. In November 1996, the Company acquired
complete  ownership  of a  Texas  HMO  in  which  it had  previously  held a 50%
interest.  That HMO began business in March 1995 and experienced  losses in both
six-month periods. In the prior period,  these losses resulted in a benefit from
minority interests.

The decrease in the effective tax rate for the first six months of 1997 to 24.0%
from  25.2%  in the  first  six  months  of 1996  resulted  from  the  Company's
investment  in  tax-preferred  investments  and the change in the  deferred  tax
valuation  allowance,  which is due primarily to the ability to use a portion of
net operating loss carryovers.

Excluding  the  effect  of the  merger-related  costs,  the  gains  on  sales of
securities,  and the prior period benefit related to minority interests,  income
before income taxes  increased  approximately  $1.5 million from the  comparable
prior  year  period.  Net income  for the six  months  ended  June 30,  1997 was
consistent with the prior year period.

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

Liquidity and Capital Resources

The Company's  cash flow from operating  activities  during the six months ended
June 30, 1997 resulted primarily from $12.0 million of net income,  $6.6 million
in  depreciation  and  amortization  and $2.2 million in provision  for doubtful
accounts  offset  by a $3.4  million  net  change  in  assets  and  liabilities,
excluding  cash and cash  equivalents.  The decrease in cash which resulted from
the change in assets and liabilities was primarily due to a decrease in unearned
premium  revenue  resulting  from early receipt of the  subsequent  month's HCFA
Medicare  capitation  payment as of December 31,  1996,  as well as increases in
accounts  receivable  and other  assets,  offset in part by increases in medical
claims payable,  the reserve for losses and loss adjustment  expense and accrued
and other liabilities.

The $61.6 million used for investing and financing activities since December 31,
1996  primarily  consisted of a $40.5 million net increase in  investments,  and
$22.0  million  in  net  capital  expenditures   including   construction  costs
associated with office and medical  facilities,  computer and medical equipment,
and other  capital  needs to support the  Company's  growth.  Additionally,  the
Company used $5.5 million to purchase treasury stock on the open market and $1.2
million for the  reduction  of debt.  On January 10,  1997,  the Company and PCA
entered into a credit and share pledge  agreement  (the "PCA Loan")  pursuant to
which the Company made a demand loan to PCA in the amount of $16.8  million with
an 8.25% fixed rate of interest.  There can be no  assurance  that PCA will have
sufficient funds to pay the PCA Loan in full. However, during the second quarter
of 1997 PCA  announced  that it had entered  into an agreement to be acquired by
Humana,  Inc., a company with  substantial  assets.  A special  meeting of PCA's
shareholders  is  scheduled  to vote  on the  proposed  merger  with  Humana  on
September  8,  1997.  These  uses of cash were  offset  in part by $7.4  million
received in connection with the sale of stock through the Company's stock plans.

In the second quarter of 1997 the Credit  Agreement was amended and increased to
$100 million.  In March 1997, the Company  borrowed $17.0 million on its line of
credit for general corporate purposes.  The remaining line of credit may be used
for  additional  working  capital,  if necessary.  Also in the second quarter of
1997, the Company's Board of Directors  authorized a $3.0 million line of credit
from the Company to the Company's  Chief  Executive  Officer ("CEO") at a market
interest rate tied to the Company's  borrowing  rate. The line of credit will be
collateralized  by certain  amounts of the CEO's Sierra stock and stock  options
and will be due and payable no later than June 30, 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  reserve  requirements.   The  HMO  and  insurance  subsidiaries  had
restricted assets on deposit in various states totaling $14.6 million as of June
30, 1997.  The HMO and insurance  subsidiaries  must also meet  requirements  to
maintain  minimum  stockholder's  equity,  on a statutory  basis,  ranging  from
$200,000  to $5.2  million.  Of the cash and cash  equivalents  held at June 30,
1997,  $45.5 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  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.

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

Liquidity and Capital Resources (continued)

The Company has  submitted a proposal as the prime  contractor  to the Office of
the Civilian Health and Medical Program of the Uniformed Services ("CHAMPUS") to
provide managed health care coverage to CHAMPUS 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, northern Virginia and Washington, D.C. The
Company expects to incur expenses of approximately $12.0 to $15.0 million during
the Region 1 contract proposal  process.  The Company submitted its final bid on
July 17,  1997 and  anticipates  learning of the result of its bid by October 1,
1997. The contract, if awarded to the Company, will result in approximately $1.8
billion in estimated  revenues  over the  five-year  term of the  contract.  The
expenses  incurred in connection  with the contract are being  deferred.  If the
Company is not  awarded the  contract,  the costs will be expensed in the period
that notification is received.

CII Financial, Inc., a California workers' compensation company that the Company
acquired in 1995, has convertible subordinated debentures (the "Debentures") due
September 15, 2001 and bearing interest at 7 1/2% which is due  semi-annually on
March 15 and September 15. Each $1,000 in principal is  convertible  into 16.921
shares of the Company's common stock at a conversion price of $59.097 per share.
The Debentures are general  unsecured  obligations of CII and are not guaranteed
by Sierra. During the six months ended June 30, 1997 Sierra purchased $30,000 of
the Debentures on the open market.

The Company has a 1997 capital budget of approximately $45.0 million,  primarily
for the construction of a new 59,000 square-foot  medical facility,  a six-story
180,000 square foot corporate  headquarters  building and  accompanying  parking
structure,  computer hardware and software,  furniture and equipment,  and other
requirements needed for the Company's projected growth and expansion. Completion
of the  medical  facility  is  expected  in the  fourth  quarter  of  1997 at an
estimated total cost of $7.3 million.  Completion of the additional  building at
the corporate  headquarters complex is expected in the fourth quarter of 1997 at
a total cost of $35.0  million.  The  Company  believes  that  existing  working
capital, operating cash flow and, if necessary, mortgage financing and equipment
leasing,  and additional  amounts  available  under its credit  facility will be
sufficient  to fund its capital  expenditures,  debt  service and any  expansion
activities  during the next 12 months.  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.

The  Company's  liquidity  needs over the next 12 months will  primarily  be for
capital items to support  growing  membership,  the Company's  stock  repurchase
program,  as well as debt  service and  expansion of the  Company's  operations,
including potential acquisitions.

Health Care Reform

Numerous  proposals  relating to health care and insurance  reform have been and
may  continue  to be  introduced  in the  United  States  Congress  and in state
legislatures.  At this time, the Company cannot determine which legislation,  if
any, will be enacted or what effect such legislation may have on the Company.

Inflation

Health care costs generally  continue to rise at a rate faster than the Consumer
Price  Index.  The Company  has been able to somewhat  lessen the impact of such
inflation by managing medical costs. There can be no assurance, however, that in
the future the Company's  ability to manage medical costs will not be negatively
impacted  by items  such as  technological  advances,  utilization  changes  and
catastrophic  items,  which could,  in turn,  result in medical  cost  increases
continuing to equal or exceed premium increases.


ITEM 3.        QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Pursuant  to the  General  Instructions  to  Rule  305 of  Regulation  S-K,  the
quantitative and qualitative  disclosures  called for by this Item 3 and by Rule
305 of Regulation S-K are inapplicable to the Company at this time.

                           PART II - OTHER INFORMATION

ITEM 1.        LEGAL PROCEEDINGS

               On March 18, 1997,  the Company  announced it had  terminated its
               merger  agreement  with  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 District Court,  seeking,  among other things,
               specific   performance  of  the  merger  agreement  and  monetary
               damages. Although the Company believes the PCA lawsuit is without
               merit,  there can be no  assurance  as to the  outcome of the PCA
               lawsuit.  The  Company has filed a motion in the  District  Court
               seeking a  dismissal  of the PCA  lawsuit.  The  Company has also
               initiated  a  lawsuit  in the Court of  Chancery  of the State of
               Delaware  seeking  a  declaratory   judgment  as  well  as  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  or that PCA will have
               sufficient  funds  to pay any  damages  that the  Company  may be
               awarded.

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

Insurance Company ("CIIC") to maintain the pledge of 10,000 shares of the common

                      SPLIT DOLLAR LIFE INSURANCE AGREEMENT



                  This Split Dollar Life Insurance  Agreement  ("Agreement")  is
made, as of ____________,  199__, by and between Sierra Health Services, Inc., a
Nevada corporation (the "Company"),  _______________(the  "Executive"),  and any
other  person,  in his or her capacity as trustee of a trust  designated  by the
Executive, as may from time to time agree to be bound by this Agreement.


                                    RECITALS

                  The  Executive  desires  to  insure  his or her  life  for the
benefit and protection of his or her family or designated  beneficiary under the
Policy (as defined below);

                  The  Company  desires to help the  Executive  provide  certain
insurance  for the benefit  and  protection  of his or her family or  designated
beneficiary by providing  funds from time to time to pay the premiums due on the
Policy, subject to reimbursement; and

                  The Executive  desires the Executive or a trust  designated by
Executive  to become the owner of the Policy  and to assign  certain  rights and
interests  in the Policy to the  Company,  to the  extent  provided  herein,  as
security  for  reimbursement  of certain  funds  provided by the Company for the
acquisition and/or maintenance of the Policy.


                                    AGREEMENT

                  NOW,  THEREFORE,  in consideration  of the foregoing,  and the
mutual  agreements and covenants set forth below,  the parties to this Agreement
agree as follows:

     1.  DEFINITIONS.  For purposes of this Agreement,  unless otherwise clearly
apparent  from the  context,  the  following  phrases  or terms  shall  have the
following indicated meanings:

                           (a)  "Aggregate  Premiums  Paid" shall  mean,  at any
         time,  an  amount  equal  to (i) the  cumulative  premiums  paid by the
         Company on the  Policy,  less (ii) any policy  loans to the Company and
         accrued and unpaid interest  thereon  (excluding any loan under Section
         6(e)(ii)),  and less (iii) any amounts received by the Company from the
         Executive for life insurance  coverage  provided under this  Agreement.
         Despite the foregoing,  Aggregate Premiums Paid shall not include extra
         benefit riders or  agreements,  other than those  providing  additional
         life insurance coverage on the insured,  and shall not include premiums
         waived  pursuant  to the  terms of any  disability  waiver of a premium
         rider. In addition, no interest shall be deemed to be accrued on and no
         present value adjustment to the cumulative premiums paid by the Company
         shall be made in calculating Aggregate Premiums Paid.

                           (b)  "Base  Annual   Compensation"   shall  mean  the
         Executive's   annual   salary  plus  an  amount  of  annual   incentive
         compensation  payable by the Company and its subsidiaries  equal to 50%
         of such annual  salary for  employment  services  in a specified  year,
         before reduction for compensation  deferred  pursuant to all qualified,
         non-qualified  and Code Section 125 plans of the  Company.  Base Annual
         Compensation  excludes  amounts  payable in connection  with  long-term
         incentive  awards   (including   compensation   resulting  from  option
         exercises),   perquisites,   other  annual  compensation  not  properly
         categorized as salary or annual incentive  compensation,  reimbursement
         of expenses,  and employee  benefits.  For purposes of determining  the
         Executive's Base Annual Compensation as of the Benefit Measurement Date
         or any other date, the Executive's  Base Annual  Compensation as of the
         most  recent  preceding  July 1 will  be used  (which  means  that  the
         Executive's  Base Annual  Compensation  will be  increased or decreased
         under this Agreement only once a year).

         under any group life  insurance  policy or program of the  Company or a
         subsidiary  (other than this Plan), and less (B) the Benefit  Reduction
         Amount  (but in no event shall  these  reductions  result in a negative
         number).  For  purposes  of this  definition,  the  "Benefit  Reduction
         Amount" shall mean the amount by which the Aggregate Premiums Paid plus
         Executive's  Death  Benefit,  calculated  without regard to the Benefit
         Reduction  Amount,  exceeds the death proceeds payable under the Policy
         assuming the maximum  cumulative  increases in the death proceeds under
         the Policy permitted by the Insurer,  over and above the death proceeds
         initially  payable under the Policy,  without requiring new evidence of
         insurability of the Executive. The foregoing notwithstanding, the death
         proceeds  initially  payable under the Policy shall be sufficient  such
         that the  Benefit  Reduction  Amount  in the  initial  year  that  this
         Agreement is in effect shall be zero.

     (j) "Insurer" shall mean Metropolitan Life Insurance Company.

                           (k) "Minimum  Retirement  Cash Value" shall mean,  on
         the  Rollout  Date,  the amount of Cash  Surrender  Value of the Policy
         payable to the Executive  (I.E.,  exclusive of portions  payable to the
         Company  under  Section  6(a))  equal to (i) the amount  sufficient  to
         maintain  a  death  benefit  that is  equal  to 1.5  multiplied  by the
         Executive's  Base  Annual  Compensation,   determined  on  the  Benefit
         Measurement  Date,  assuming  that  the  Policy  will be  held  without
         surrender,  withdrawal or loan by the Executive for 20 years  following
         the  Benefit  Measurement  Date and  using the  Insurer's  then-current
         interest  rate and  expense  loads  under the Policy as of the  Rollout
         Date, multiplied by (ii) 1.6667.

                           (l)  "Permanently  Disabled" shall mean the Executive
         is unable to perform the usual  assigned  duties of his or her position
         (i) due to a disability  which  qualifies the Executive for  disability
         benefits under the Company's  long-term  disability  plan,  (ii) if the
         Executive  does not  participate  in such a plan,  due to a  disability
         which would have qualified the Executive for disability  benefits under
         such a plan had the  Executive  been a  participant  in such a plan, or
         (iii), if the Company does not sponsor a long-term disability plan, due
         to a physical or mental disease, injury or infirmity, of long duration,
         as determined by the Committee in its sole discretion.

     (m) "Plan" shall mean the plan described in Section 8(a) below.

     (n) "Policy" shall mean the following policy or policies on the life of the
Executive that are issued by the Insurer:

                           POLICY NUMBER    TYPE OF POLICY

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

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

                           (o)  "Retirement"  or "Retire"  shall mean  severance
         from  employment  from  the  Company  for  any  reason  other  than  an
         authorized  leave of  absence  or death on or after the  earlier of the
         attainment of (i) age 65 ("Normal  Retirement")  or (ii) age 55 and ten
         Years of Service  ("Early  Retirement").  In addition,  a person who is
         Permanently  Disabled  (regardless of his or her employment status with
         the Company) and who reaches age 55 shall be treated as having  reached
         Retirement under this Agreement. For purposes of the foregoing,  "Years
         of  Service"  shall  mean the total  number of full  years in which the
         Executive  has been  employed  by the  Company.  For  purposes  of this
         definition,  a year of employment shall be a 365-day period (or 366-day
         period in the case of a leap year) commencing on the date of hiring and
         each  anniversary  thereof  (subject to  adjustment  to reflect  unpaid
         leaves of absence of more than 90 days). A Participant's  paid leave of
         absence or unpaid leave of absence for 90 days or less shall constitute
         employment for purposes of this definition,  but a Participant's unpaid
         leave of absence for more than 90 days shall not constitute  employment
         for purposes of this definition.

                           (p)  "Rollout  Date"  shall  mean  the  later  of the
         Benefit  Measurement  Date or the fifteenth  anniversary of the date of
         this Agreement,  but in no event later than the death of the Executive;
         provided,  however, that the Company may accelerate the Rollout Date to
         a date  specified  by the  Company,  but in no event  earlier  than the
         Benefit  Measurement  Date,  and only if at such  Rollout Date the Cash
         Surrender Value equals or exceeds the Minimum Retirement Cash Value.

                           (q)  "Tax  Limitation  Date"  shall  mean the date on
         which the  Policy  will no longer be  subject  to those  provisions  of
         Section  7702(f)(7)  of the Code that would cause any  distribution  or
         surrender  from or under the Policy to be taxed under that  Section (or
         Section 72 of the Code by reason of that Section).

                           (r)  "Termination  of  Employment"   shall  mean  the
         ceasing of Executive's employment with the Company for any reason other
         than Retirement,  death, a Permanent Disability, or an authorized leave
         of absence.

                  2.       ACQUISITION OF POLICY; OWNERSHIP OF INSURANCE.

     (a) Cooperation  With Respect to the Policy.  The parties to this Agreement
shall cooperate in applying for,  obtaining,  and maintaining the Policy, and in
obtaining any increase in coverage of the Policy.

                           (b)  Ownership  of the  Policy.  The Policy  shall be
         issued to the  Executive or to a trust  designated  by the Executive in
         accordance  with this Section 2(b). If the Policy is originally  issued
         to the  Executive,  the  Executive  may  transfer the Policy to a trust
         designated  by the  Executive,  if such  transfer  is  approved  by the
         Company.  The  trustee,  on behalf  of a trust to which  the  Policy is
         issued or transferred,  must execute a copy of this Agreement and agree
         to be bound by the terms  hereof.  The  Executive  or the  trustee,  on
         behalf of such a  designated  trust,  as the case may be,  shall be the
         sole and  exclusive  owner of the  Policy,  subject  to the  rights and
         interests granted to the Company, as provided in this Agreement and the
         Collateral  Assignment.  The Executive and any such trustee acknowledge
         and agree that the Company and its agents have not provided advice with
         respect to Executive's estate planning.

                  3.       PREMIUM PAYMENTS ON POLICY.

                           (a)  Payments  and   Reimbursements.   Prior  to  the
         occurrence of the Rollout  Date,  the Company shall pay to the Insurer,
         on or before each applicable premium due date, all applicable  premiums
         for the Policy.  In the event that the  Company  fails to make any such
         payment, the Executive or any trust which then owns the Policy may make
         (but is not required to make) any such  payment,  and the Company shall
         immediately  reimburse  the  Executive  or such trust for any amount so
         paid.  All  such  premium  payments  made  by the  Company  under  this
         Agreement shall constitute advances by the Company to the Executive for
         which the  Executive  or any trust  then  owning  the  policy  shall be
         responsible  for  reimbursement  in  accordance  with the terms of this
         Agreement,  but only up to an amount equal to the Company's  Collateral
         Interest.  The Company does not  guarantee the Policy or the payment of
         any death benefit or other amount thereunder to the Executive or his or
         her  Beneficiaries,  nor is the Company  otherwise  obligated to pay or
         provide any benefit to the Executive by virtue of this Agreement except
         for the payment of  premiums on the terms and subject to  reimbursement
         as specified in this Agreement.

                           (b) Prefunding Upon a Change in Control. In the event
         of a Change in Control, the Company shall, not later than 45 days after
         such  event,  pay to the  Insurer  an amount  sufficient  to prepay all
         premiums  for the  Policy  through  the  earlier  of the  date on which
         Executive  will be eligible for Normal  Retirement or the date one year
         after the Change in Control.  The Company  will arrange for the Insurer
         to apply such  prefunding  payments to premiums or hold such prefunding
         payments in a premium reserve  account,  which shall be  non-refundable
         (without regard to whether Executive's  employment  terminates prior to
         the end of the period covered by such prefunding).

                           (c) Additional Compensation.  Each calendar year, the
         Executive shall be considered to have taxable  compensation  income for
         that  portion  of the  premiums  paid by the  Company  that is equal in
         amount to the value of the "economic  benefit" derived by the Executive
         from the Policy's life insurance protection,  as determined for Federal
         income tax purposes under Revenue  Rulings  64-328 and 66-110,  and may
         have other taxable income under other  applicable tax  regulations  and
         authorities.  The Company  shall  withhold  from the  Executive's  Base
         Annual Compensation,  or other compensation paid to the Executive, in a
         manner  determined by the Company,  the  Executive's  share of FICA and
         other  employment  and  income  taxes  required  to be  withheld  under
         applicable tax regulations and authorities.

                  4.       COMPANY'S RIGHTS.

     (a)  Generally.  The  Company's  rights and  interests in and to the Policy
shall be

         specifically  limited  to (i)  the  right  to be  paid  its  Collateral
         Interest in accordance with Section 6 below,  (ii) the rights specified
         in the Collateral Assignment,  (iii) the Company's rights under Section
         4(b) and (iv) the right to obtain one or more loans or  advances on the
         Policy,  provided,  however,  that any such  loans  shall  not,  in the
         aggregate,  result in the  Aggregate  Premiums Paid becoming a negative
         amount  at any  specified  date  without  the  written  consent  of the
         Executive,  and  provided  further,  that prior to any Rollout date the
         Company shall repay any such loans, including accrued interest thereon,
         to the extent  necessary so that the Aggregate  Premiums Paid shall not
         be a negative amount at the Rollout Date.

                           (b)  Investment  Decisions.  Until  such  time as the
         Company's  Collateral Interest has been settled under Section 6(b), the
         Company  shall have the  exclusive  right to  exercise  the  investment
         discretion,  if any,  under the Policy  that the Policy may confer upon
         the  Executive or any other person.  After  settlement of the Company's
         Collateral  Interest,  the  Executive  or any other owner of the Policy
         shall have the right to exercise such  investment  discretion (if any),
         without consultation with or participation by the Company.

                  5.  EXECUTIVE'S  RIGHTS  AND  RIGHTS  OF  TRUSTEE  AS OWNER OF
POLICY.  Subject to the terms of this  Agreement and the  Collateral  Assignment
(and any  agreement or deed of trust between the Executive and any trustee which
may become the owner of the Policy in trust),  the Executive or the trustee of a
trust designated under Section 2(b) shall be the owner of the Policy,  and shall
be entitled to exercise all rights in the Policy while the Collateral Assignment
is in  effect,  except  for  the  following,  which  may be  exercised  only  in
accordance with Section 6:

                           (a)      To borrow against or pledge the Policy;

                           (b)      To surrender, cancel or assign the Policy;

     (c) To take a distribution or withdrawal from the Policy; or

     (d) To exercise investment  discretion under the Policy, except as provided
in Section 4(b).

                  6.       COLLATERAL INTEREST.

                           (a) On the Rollout Date,  the  Company's  interest in
         the Policy  (the  "Collateral  Interest")  shall be  determined  in the
         following manner:

                                    (i) If the Benefit Measurement Date occurred
                  due to the  Executive's  Retirement or due to a termination of
                  this Agreement by the Company  subject to Section  9(b)(i) and
                  the Rollout Date did not occur due to Executive's  death,  the
                  Company  shall be entitled to receive from the  Policy's  Cash
                  Surrender  Value (or otherwise,  as specified in Section 6(b))
                  at the Rollout  Date an amount  equal to the lesser of (i) the
                  Aggregate Premiums Paid or (ii) the Cash Surrender Value minus
                  the Minimum Retirement Cash Value (if this calculation results
                  in a negative number, the Company's  Collateral Interest shall
                  be zero).

                                    (ii)  If  the   Benefit   Measurement   Date
                  occurred due to the  Executive's  Termination of Employment or
                  the  termination  of this Agreement by either party subject to
                  Section  9(b)(ii) below and the Rollout Date did not occur due
                  to Executive's death, the Company shall be entitled to receive
                  from the  Policy's  Cash  Surrender  Value (or  otherwise,  as
                  specified in Section 6(b)) at the Benefit  Measurement Date an
                  amount equal to that portion of the  Policy's  Cash  Surrender
                  Value up to but not exceeding the Aggregate Premiums Paid.

                                    (iii)  If the  Benefit  Measurement  Date or
                  Rollout Date occurred due to the death of the  Executive,  the
                  Company  shall be  entitled  to that  portion of the  Policy's
                  death  proceeds that exceeds the  Executive's  Death  Benefit,
                  except as provided in Section 6(a)(iv)

                  below.

                                    (iv)  If the  Benefit  Measurement  Date  or
                  Rollout Date occurred due to the suicide of the Executive, and
                  the death  proceeds  from the Policy  are  limited by either a
                  suicide or contestability provision under the Policy such that
                  the amount  payable to the  Company  under  Section  6(a)(iii)
                  would be less than the Aggregate Premiums Paid with respect to
                  the Policy or the  portion  thereof so  limited,  the  Company
                  shall be entitled to that portion of the Cash Surrender  Value
                  and/or  death  proceeds  resulting  from the Policy or portion
                  thereof so limited that does not exceed the Aggregate Premiums
                  Paid with respect to the Policy or portion thereof so limited.

                           (b) If the Benefit  Measurement Date and Rollout Date
         are each on a date other than the date of the  Executive's  death,  the
         Company's  Collateral  Interest in the Policy, as determined in Section
         6(a)(i)  and (ii)  above,  shall be paid to the  Company  in one of the
         following  ways, as elected by the Executive or the trustee then owning
         the  Policy  in trust  (if the  power to make  this  election  has been
         transferred to such owner by the Executive),  in writing within 30 days
         after the date the Company first notifies the Executive or such trustee
         in writing of the  occurrence of the Rollout  Date,  if the  Collateral
         Interest  is  determined   under  Section   6(a)(i),   or  the  Benefit
         Measurement  Date,  if the  Collateral  Interest  is  determined  under
         Section 6(a)(ii):

                                    (i) By the  Executive's  or  such  trustee's
                  surrender or partial  surrender  of, or withdrawal  from,  the
                  Policy  in  an  amount  equal  to  the  Company's   Collateral
                  Interest,  and the payment of the cash proceeds thereof to the
                  Company;

                                    (ii) By the Executive or such trustee taking
                  a loan out on the Policy in an amount  equal to the  Company's
                  Collateral  Interest,  and payment of the loan proceeds to the
                  Company,  provided that the Company  shall not be  responsible
                  for repayment of any principal of or interest accruing on such
                  loan;

                                    (iii) By the  Executive's  or such trustee's
                  payment to the  Company,  from other  funds  available  to the
                  Executive or such  trustee,  an amount equal to the  Company's
                  Collateral Interest; or

                                    (iv) By the  Executive's  or such  trustee's
                  transfer  of the  ownership  of the  Policy,  and  all  rights
                  thereunder,  to the Company,  provided that the Cash Surrender
                  Value  of the  Policy  is at  least  equal  to  the  Company's
                  Collateral Interest at the time of the transfer.

         The  Company's  Collateral  Interest in the Policy shall be paid to the
         Company as soon as is reasonably practical after the Rollout Date.

                           (c) If the Benefit  Measurement  Date or Rollout Date
         is the date of the Executive's death, the Company's Collateral Interest
         in the Policy, as determined in Section 6(a)(iii) above,  shall be paid
         to the Company  from the  Policy's  proceeds  as soon as is  reasonably
         practicable after the Executive's death.

                           (d)  Despite  Section  6(b)  above and  Section  6(e)
         below, if, at the time the Company's Collateral Interest is determined,
         the Tax  Limitation  Date has not occurred,  (i) the Company shall have
         the right,  in its sole  discretion,  to require the  Executive  or the
         trustee  then owning the Policy in trust to elect to pay the  Company's

         the  Company's  rights under  Section 6(e) shall be limited to taking a
         loan in accordance with Section 6(e)(ii) below.

                           (e) If the  Executive  or the trustee then owning the
         Policy in trust fails to exercise any of the options under Section 6(b)

         the  occurrence of an event whereby the Company's  Collateral  Interest
         has been determined, the Company shall be entitled to: (i) exercise the
         right  to  surrender  the  Policy  and to  receive  the  Policy's  Cash
         Surrender Value, to the extent of the Company's Collateral Interest, or
         (ii) take out a loan on the Policy in an amount equal to the  Company's
         Collateral Interest, with the loan proceeds paid to the Company and the
         Company not  responsible  for  repayment  of  principal  of or interest
         accruing  on  such  loan,  or  (iii)  transfer  the  ownership  of  and
         beneficial interest in the Policy to the Company. In the case of (i) or
         (iii) above, the Company shall pay to the Executive,  if he or she then
         owns the Policy,  or to the trustee of the trust then owning the Policy
         in trust,  the Cash Surrender Value or death proceeds that remain after
         the Company has been paid its Collateral Interest.

                           (f) The Company agrees to keep records of its premium
         payments and to furnish the Insurer with a statement of its  Collateral
         Interest  (with a copy to the  Executive and to the trustee then owning
         the Policy in trust) whenever the Insurer requires such statement.

                           (g)  Concurrent  with the signing of this  Agreement,
         the  Executive  or the  trustee  which  owns or will own the  Policy in
         trust, will collaterally  assign the Policy to the Company, in the form
         of the  Collateral  Assignment,  as  security  for the  payment  of the
         Collateral  Interest,  which assignment shall not be altered or changed
         without the written consent of the Company, the Executive, and any such
         trustee.

                           (h) Promptly  following the  Executive's  death,  the
         Company and the  Executive's  designated  beneficiary  under the Policy
         shall take all steps  necessary  to collect  the death  proceeds of the
         Policy by  submitting  the  proper  claims  forms to the  Insurer.  The
         Company shall notify the Insurer of the amount of the Executive's Death
         Benefit  (subject to  adjustment  if the Policy's  proceeds are limited
         because  of  the  Executive's  death  by  suicide)  and  the  Company's
         Collateral  Interest  in the  Policy  at the time of such  death.  Such
         amounts shall be paid, respectively,  by the Insurer to the Executive's
         designated beneficiary and the Company.

                           (i) If the  Executive  or the trustee of a trust then
         owning  the  Policy  elects to retain  the  Policy in  accordance  with
         Section  6(b)  above,  the  Company  shall (i)  assign  its  Collateral
         Interest in the Policy to the  Executive or such  trustee,  as the case
         may be, (ii) execute and file with the Insurer an  appropriate  release
         of the  Company's  Collateral  Interest in the Policy and (iii) have no
         further  interest in the Policy;  provided that, in all instances,  the
         Company  receives  payment in full for its  Collateral  Interest in the
         Policy.  Further,  the Executive hereby  acknowledges,  understands and
         agrees that, upon the release of the Company's Collateral Interest, the
         Company shall not have any responsibility for the future performance of
         the Policy and shall have no obligation to make any additional  premium
         payments.

                           (j) If the  Executive  or the trustee of a trust then
         owning the Policy elects to transfer the Policy to the Company,  or the
         Company  makes such an election in  accordance  with Section  6(e)(iii)
         above, the Executive or such trustee shall sign all documents necessary
         to transfer the Policy to the Company, and the Executive, such trustee,
         and any  beneficiary  designated  by Executive or  beneficiary  of such
         trust or other party (other than the Company)  with a right or interest
         in the Policy from or through the Executive or such trust shall have no
         further right or interest in and to the Policy.

                           (k) Upon  payment to the  Company  of its  Collateral
         Interest in  accordance  with this Section 6, this  Agreement,  and the
         Executive's  participation in the Plan,  shall terminate,  and no party
         shall have any further rights or obligations under the Agreement or the
         Plan.

                  7.       INSURER.

                           (a) The  Insurer  is not a party  to this  Agreement,
         shall in no way be bound by or charged with notice of its terms, and is
         expressly  authorized to act only in  accordance  with the terms of the
         Policy.

         Split-Dollar   Life  Insurance   Agreements  that  so  reference  their
         association with the Plan.

                           (b) The  Company is the named  fiduciary  of the Plan
         for  purposes of this  Agreement.  The Plan is  administered  by a Plan
         Administrator  which  consists  of the  Compensation  Committee  of the
         Company's  Board of  Directors  or such  committee  as the Board  shall
         appoint.

                           (c) The following  claims procedure shall be followed
         in handling any benefit claim under this Agreement and the Plan:

                  then owning the Policy,  or any  beneficiary  of  Executive if
                  Executive  is dead (the  "Claimant"),  may deliver to the Plan
                  Administrator a written claim for a determination with respect
                  to the benefits  distributable to such Claimant hereunder.  If
                  such a claim  relates to the contents of a notice  received by
                  the Claimant, the claim must be made within 60 days after such
                  notice was received by the Claimant. The claim must state with
                  particularity the determination  desired by the Claimant.  All
                  other claims must be made within 180 days of the date on which
                  the event that caused the claim to arise  occurred.  The claim
                  must state with particularity the determination desired by the
                  Claimant.

                                    (ii) The Plan Administrator shall consider a

claim has been allowed in full; or

                                            (B) that the Plan  Administrator has
                           reached a conclusion  contrary,  in whole or in part,
                           to the Claimant's requested  determination,  and such
                           notice  must set forth in a manner  calculated  to be
                           understood by the Claimant:

     (1) the specific reason(s) for the denial of the claim, or any part of it;

     (2) specific  reference(s)  to pertinent  provisions of the Plan upon which
such denial was based;

the Claimant to perfect the claim,  and an  explanation  of why such material or
information is necessary; and

discretion, may grant.

manner calculated to be understood by the Claimant, and it must contain:

                  at a time that the Executive's termination of employment would
                  qualify as a "Retirement," the Company's  Collateral  Interest
                  shall be determined under Section 6(a)(i); and

                                    (ii) If the Company terminates the Agreement

specific rights included in this Assignment.

                  7. AMENDMENT OF ASSIGNMENT; TERMINATION. This Assignment shall
not be  modified,  amended  or  terminated,  except by a  writing  signed by the

Assignment  may be  terminated  by the  Company or the  Executive  if that Party
terminates  the Agreement in accordance  with Section 9 of the Agreement and the
obligations of the party  terminating  the Agreement are performed in full under
the Agreement.

                  8.  BINDING  AGREEMENT;  ASSIGNS.  This  Assignment  shall  be
binding upon the heirs,  administrators,  executors and permitted successors and
assigns of each party to this  Assignment.  The Executive and/or the Trustee (if
any) shall not assign his or her  rights or  obligations  under this  Assignment
without the prior written consent of the Company.

     9.  GOVERNING  LAW. This  Assignment  shall be subject to and construed and
interpreted under the internal laws of the State of Nevada without regard to its
conflicts of laws principles.

                  10.  VALIDITY.  In case any provision of this Assignment shall
be illegal or invalid for any reason,  said  illegality or invalidity  shall not
affect the remaining  parts of this  Assignment,  but this  Assignment  shall be
construed  and enforced as if such illegal or invalid  provision  had never been
inserted herein.

1.16     "Company   Restoration  Account"  shall  mean  the  sum  of  all  of  a
         Participant's  Annual Company Restoration Amounts plus amounts credited
         and debited in  accordance  with all the  applicable  provisions of the
         Plan,  less all  distributions  made to the  Participant  or his or her
         Beneficiary  pursuant  to the Plan that  relate  to his or her  Company
         Restoration Account. This account shall be a bookkeeping entry only and
         shall  be  utilized   solely  as  a  device  for  the  measurement  and
         determination of the amounts to be paid to the Participant  pursuant to
         this Plan.

1.17     "Deferral Account" shall mean the sum of all of a Participant's  Annual
         Deferral Amounts,  plus amounts credited and debited in accordance with
         all the applicable  provisions of the Plan, less all distributions made
         to the Participant or his or her Beneficiary  pursuant to the Plan that
         relate  to  his  or her  Deferral  Account.  This  account  shall  be a
         bookkeeping entry only and shall be utilized solely as a device for the
         measurement  and  determination  of  the  amounts  to be  paid  to  the
         Participant pursuant to this Plan.

1.18     "Deduction Limitation" shall mean the following described limitation on
         a  benefit  that  may  otherwise  be  distributable   pursuant  to  the
         provisions of this Plan. Except as otherwise provided,  this limitation
         shall  be  applied  to  all  distributions  that  are  "subject  to the
         Deduction  Limitation"  under this Plan.  If an Employer  determines in
         good  faith  prior to a Change in Control  that  there is a  reasonable
         likelihood  that any  compensation  paid to a Participant for a taxable
         year of the Employer would not be deductible by the Employer  solely by
         reason of the limitation under Code Section 162(m),  then to the extent
         deemed  necessary by the  Employer to ensure that the entire  amount of
         any distribution to the Participant  pursuant to this Plan prior to the
         Change in  Control is  deductible,  the  Employer  may defer all or any
         portion  of a  distribution  under  this  Plan.  Any  amounts  deferred
         pursuant  to  this  limitation  shall  be  credited  and  debited  with
         additional  amounts in accordance with Section 3.8 below,  even if such
         amount is being  paid out in  installments.  The  amounts  so  deferred
         adjusted  to reflect  amounts  credited  and debited  thereon  shall be
         distributed to the  Participant or his or her Beneficiary (in the event
         of  the  Participant's   death)  at  the  earliest  possible  date,  as
         determined by the Employer in good faith, on which the deductibility of
         compensation paid or payable to the Participant for the taxable year of
         the Employer during which the  distribution is made will not be limited
         by Section  162(m),  or if earlier,  the effective  date of a Change in
         Control.  Notwithstanding  anything to the  contrary in this Plan,  the
         Deduction  Limitation shall not apply to any distributions made after a
         Change in Control.

1.19     "Disability"   shall  mean  a  period  of  disability  during  which  a
         Participant  qualifies for disability  benefits under the Participant's
         Employer's  long-term  disability  plan, or, if a Participant  does not
         participate  in such a plan,  a period of  disability  during which the
         Participant  would have qualified for disability  benefits under such a
         plan  had  the  Participant  been a  participant  in  such a  plan,  as
         determined   in  the  sole   discretion  of  the   Committee.   If  the
         Participant's Employer does not sponsor such a plan, or discontinues to
         sponsor such a plan, Disability shall be determined by the Committee in
         its sole discretion.

1.20     "Disability Benefit" shall mean the benefit set forth in Article 8.

1.21     "Election  Form" shall mean the form  established  from time to time by
         the Committee  that a Participant  completes,  signs and returns to the
         Committee to make an election under the Plan.

1.22     "Employee" shall mean a person who is an employee of any Employer.

1.23     "Employer(s)"  shall mean the  Company  and/or any of its  subsidiaries

paid. The result of this multiplication  shall be the amount of each installment
payment for the Plan Year in which the  Participant  Retired,  died,  suffered a

Year,  in  accordance  with Section 3.8,  after taking into account all previous
installment  payments,  and such  balance  shall be  multiplied  by the fraction
described  above,  except that the denominator  shall be the number of remaining
periods over which the installment payments are to be paid. The resulting amount

2.1      SELECTION BY COMMITTEE. Participation in the Plan shall be limited to a
         select  group of  management  or highly  compensated  Employees  of the
         Employers, as determined by the Committee in its sole discretion.  From

         future  deferral  elections  and/or (iii)  immediately  distribute  the
         Participant's then Account Balance, determined as if there has occurred
         a   Termination   of  Employment   and   terminate  the   Participant's
         participation  in the Plan. If the  Committee  chooses to terminate the
         Participant's participation in the Plan, the Committee may, in its sole
         discretion,  reinstate the  Participant to full Plan  participation  at
         such time in the future as the  Participant  again  becomes a member of

                  first Plan Year itself, for such Plan Year only, a Participant

                  along  with  such  other  elections  as  the  Committee  deems
                  necessary or desirable  under the Plan. For these elections to

                  necessary or desirable under the Plan, shall be made by timely
                  delivering to the Committee,  in accordance with its rules and
                  procedures, before the end of the Plan Year preceding the Plan
                  Year for which the election is made, a new Election  Form.  If

                  Annual Deferral Amount shall be withheld for that Plan Year.

3.4      WITHHOLDING OF ANNUAL  DEFERRAL  AMOUNTS.  For each Plan Year, the Base
         Annual Salary portion of the Annual  Deferral  Amount shall be withheld
         in equal  amounts  from each  regularly  scheduled  Base Annual  Salary
         payroll.  The Annual Bonus portion of the Annual  Deferral Amount shall
         be withheld at the time the Annual Bonus is or otherwise  would be paid
         to the  Participant,  whether or not this  occurs  during the Plan Year
         itself.

     3.5  ANNUAL  COMPANY  MATCHING  AMOUNT.  If,  and only  if,  a  Participant
participates  in the 401(k) Plan  ------------------------------  to the maximum
extent  possible under the limits  applicable to the Plan for the Plan Year, the
Participant's  Annual Company  Matching Amount for such Plan Year shall be equal
to 50% of the Participant's  Annual Deferral Amount for such Plan Year, up to an
amount  that does not exceed the lesser of 5% of the  Participant's  Base Annual
Salary  or 50% of the IRC  402(g)(i)  limit in the  effect  for the  Plan  Year,
reduced by the amount of any Company matching  contributions  made to the 401(k)
Plan on his or her behalf for the plan year of the 401(k) Plan that  corresponds

Participant's  Company  Matching  Account as of the first day of February of the
Plan Year  following  the Plan  Year to which it  relates.  Notwithstanding  the
above,  if a Participant  is not employed by an Employer as of the last day of a
Plan Year other than by reason of his or her  Retirement,  Disability  or death,
the Annual  Company  Matching  Amount  for such Plan Year shall be zero.  In the

         matching contributions under the 401(k) Plan which would have been made

         on or  after  July 1,  1997  for  such  Plan  Year  but for one or more
         limitations imposed by the 401(k) Plan pursuant to the Code,  including
         but not limited to any such amounts  resulting from the  application of
         the compensation  limitations  contained in Code Section  401(a)(17) or
         the  limitations  contained  in Code  Section 415. For purposes of this
         Section  3.6,  employer  contributions  under the 401(k)  Plan  exclude
         contributions resulting from the cash or deferred arrangement under the
         401(k) Plan but include  contributions  resulting from the reallocation
         of prior  employer  contributions  (other than matching  contributions)
         forfeited  by  other  401(k)  Plan  participants.  The  Annual  Company
         Restoration  Amount  shall be  credited  to the  Participant's  Company
         Restoration  Account  as of the date or dates such  amounts  would have
         been allocated to the Participant's account(s) under the 401(k) Plan if
         such  amounts had in fact been  allocated  under the 401(k)  Plan.  The
         foregoing  notwithstanding  the above, if a Participant is not employed
         by an  Employer  as of the last day of a Plan Year other than by reason
         of his or her  Retirement,  Disability  or death,  the  Annual  Company
         Restoration  Amount for such Plan Year  shall be zero.  In the event of
         Retirement,  Disability or death, a Participant  shall be credited with
         the Annual Company  Restoration Amount for the Plan Year in which he or
         she

     (a) ELECTION OF MEASUREMENT FUNDS. A Participant, in connection with his or
her initial  -----------------------------  deferral election in accordance with
Section 3.3(a) above, shall elect, on the Election Form, one or more Measurement
Fund(s) (as  described  in Section  3.8(c)  below) to be used to  determine  the
additional  amounts to be credited or debited to his or her Account Balance (and
Unvested  Accrued  Amounts)  from the date on which  the  Participant  commences
participation  in  the  Plan  and  continuing  thereafter,   unless  changed  in
accordance  with the next  sentence.  Commencing  with the  January  1 or July 1
("Investment  Election  Date") that follows the  Participant's  commencement  of
participation in the Plan and on each subsequent Investment Election Date during
which the Participant  participates in the Plan, no later than the day before an
Investment Election Date, the Participant may (but is not required to) elect, by
submitting an Election Form to the Committee  that is accepted by the Committee,
to add or delete one or more  Measurement  Fund(s) to be used to  determine  the
amounts to be credited or debited to his or her Account  Balance  (and  Unvested
Accrued  Amounts),  or to change the portion of his or her Account  Balance (and

                  Accrued Amounts) allocated to each previously or newly elected
                  Measurement  Fund. If an election is made in  accordance  with
                  the previous  sentence,  it shall apply to the next Investment
                  Election  Date and  continue  thereafter,  unless  changed  in
                  accordance  with the previous  sentence.  Notwithstanding  the
                  foregoing,  the  maximum  transfer  that may be made  from the
                  Declared Rate Measurement Fund to another  Measurement Fund in
                  any one Plan Year cannot exceed 20% of the maximum  balance in
                  the  Participant's  account in the Declared  Rate  Measurement
                  Fund in the current Plan Year and the four prior Plan Years.

         (b)      PROPORTIONATE  ALLOCATION. In making any election described in
                  Section  3.8(a) above,  the  Participant  shall specify on the
                  Election Form, in whole percentage points (1%), the percentage
                  of his or her Account Balance (and Unvested  Accrued  Amounts)
                  to be allocated to a Measurement  Fund (as if the  Participant
                  was making an  investment in that  Measurement  Fund with that
                  portion of his or her  Account  Balance and  Unvested  Accrued
                  Amounts).

     (c) MEASUREMENT  FUNDS.  The Participant may elect one or more  measurement
funds,  -----------------  based  on  certain  mutual  funds  (the  "Measurement
Funds"),  for the purpose of crediting or debiting amounts to his or her Account
Balance (and Unvested  Accrued  Amounts).  The Committee shall select the mutual
funds that are to be used as Measurement Funds. As necessary, the Committee may,
in its sole discretion, discontinue, substitute or add a Measurement Fund at any
time.  Each such  action  will take  effect as of the first day of the  calendar
quarter  that follows by thirty (30) days the day on which the  Committee  gives
Participants advance written notice of such change. In addition, a Declared Rate
Measurement Fund shall be maintained under which interest shall be credited at a
rate as specified by the Company on the November 1 of the year prior to the Plan
Year for which the amount of  interest  is being  determined.  In the first Plan
Year, the rate of interest on the Declared Rate  Measurement Fund shall be equal
to 8.75%.

     (d)  CREDITING  OR  DEBITING  METHOD.  The  performance  of  each  selected
Measurement Fund ---------------------------- (either positive or negative) will
be determined by the Committee in its sole  discretion  based on the performance
of the  Measurement  Funds  themselves  or,  in the  case of the  Declared  Rate
Measurement  Fund, based on the amount of accrued interest credited to the fund.
A Participant's Account Balance (and Unvested Accrued Amounts) shall be credited
or debited based on such  performance of the Measurement  Funds as determined by
the Committee in its sole discretion.  As of each Investment  Election Date, the
Committee shall  distribute to the  Participants a statement of their respective
Account Balances (and Unvested Accrued Amounts).  Furthermore, in the event of a
Participant's   termination  of  employment  or  any  other  event  requiring  a
determination  of the  Participant's  Benefit  or the  value of a  Participant's
Account  Balance,   the  Account  Balance  shall  be  determined  based  on  the
performance of the relevant Measurement Fund(s) through the last date of the pay
period  during  which  the  event  occurs  and  shall  not be  further  adjusted
thereafter.

     (e) NO ACTUAL INVESTMENT.  Notwithstanding any other provision of this Plan
that may be interpreted to the contrary,  the  Measurement  Funds are to be used
for  measurement  purposes  only,  and a  Participant's  election  of  any  such
Measurement Fund, the

                  allocation to his or her Account Balance (and Unvested Accrued
                  Amounts)  thereto,  the calculation of additional  amounts and
                  the  crediting or debiting of such amounts to a  Participant's
                  Account  Balance (and Unvested  Accrued  Amounts) shall not be
                  considered or construed in any manner as an actual  investment
                  of his or her Account Balance (or Unvested Accrued Amounts) in
                  any such  Measurement  Fund.  In the event that the Company or
                  the Trustee (as that term is defined in the Trust), in its own
                  discretion,  decides  to  invest  funds  in  any or all of the
                  Measurement  Funds, no Participant shall have any rights in or
                  to  such   investments   themselves.   Without   limiting  the
                  foregoing,  a  Participant's  Account  Balance  (and  Unvested
                  Accrued  Amounts)  shall at all times be a  bookkeeping  entry
                  only and shall not represent any investment made on his or her
                  behalf by the Company or the Trust;  the Participant  shall at
                  all times remain an unsecured creditor of the Company.

3.9      FICA,  WITHHOLDING  AND  OTHER  TAXES.  For each  Plan Year in which an
         Annual Deferral Amount is being withheld or an Annual Company  Matching
         Amount  or  Annual  Company   Restoration   Amount  is  credited  to  a
         Participant,  the  Participant's  Employer(s)  shall withhold from that
         portion of the  Participant's  Base Annual  Salary  and/or Annual Bonus
         that is not being deferred,  in a manner determined by the Employer(s),
         the  Participant's  share  of  FICA  and  other  employment  taxes.  If
         necessary,  the Committee  shall reduce the Annual  Deferral  Amount in
         order to comply with this Section 3.9. In addition,  the  Participant's
         Employer(s)  or the Trust,  shall  withhold from any payments made to a
         Participant  under  this Plan all  federal,  state  and  local  income,
         employment and other taxes  required to be withheld in connection  with
         such payments,  in amounts and in a manner to be determined in the sole
         discretion of the Employer(s) or the Trust.

3.10     ROLLOVERS  FROM PRIOR  DEFERRED  COMPENSATION  PLAN. A Participant  who
         participated in the Company's prior nonqualified  deferred compensation
         plan shall  have the  right,  under such rules and at such times as are
         prescribed  by the  Committee,  to  roll  over  the  benefit  that  the
         Participant is entitled to receive pursuant to such prior  nonqualified
         deferred  compensation  plan so that  such  amount  shall  be held  and
         administered  pursuant  to the terms of this Plan and shall be received
         at the same time that benefits are received pursuant to this Plan.

             Short-Term Payout; Unforeseeable Financial Emergencies;
                               Withdrawal Election

4.1      SHORT-TERM  PAYOUT. In connection with each election to defer an Annual
         Deferral   Amount,   a  Participant  may  elect  to  receive  a  future
         "Short-Term  Payout" from the Plan with respect to that Annual Deferral
         Amount.  Subject to the Deduction  Limitation,  the  Short-Term  Payout
         shall be a lump sum  payment  in an amount  that is equal to the Annual
         Deferral Amount plus amounts credited or debited in the manner provided
         in  Section  3.8 above on that  amount,  determined  at the time of the
         Short-Term  Payout  becomes  payable.  Subject  to the other  terms and
         conditions of this Plan, each Short-Term  Payout elected shall be paid,
         subject to the Deduction Limitation, within 60 days of the first day of
         the Plan Year  that is at least  four  years  after the last day of the
         Plan Year in which the Annual Deferral Amount is actually deferred.  By
         way of example,  if a Short-Term Payout is elected for amounts that are
         deferred in the Plan Year  commencing  January 1, 1997,  the Short-Term
         Payout becomes payable within 60 days of January 1, 2002.

4.2      OTHER BENEFITS TAKE PRECEDENCE OVER SHORT-TERM PAYOUT.  Should an event
         occur that triggers a benefit  under  Articles 5, 6, 7 or 8, any Annual
         Deferral  Amount,  plus amounts  credited or debited  thereon,  that is
         subject to a Short-Term  Payout election under Section 4.1 shall not be
         paid in  accordance  with  Section 4.1 but shall be paid in  accordance
         with the other applicable Article.

     4.3 WITHDRAWAL  PAYOUT/SUSPENSIONS FOR UNFORESEEABLE FINANCIAL EMERGENCIES.
If                                the                                Participant
- ---------------------------------------------------------------------
experiences an Unforeseeable  Financial Emergency,  the Participant may petition
the Committee to (i) suspend any deferrals  required to be made by a Participant
and/or (ii) receive a partial or full payout from the Plan. The payout shall not
exceed the lesser of the  Participant's  Account Balance,  calculated as if such
Participant  were  receiving a  Termination  Benefit,  or the amount  reasonably
needed to satisfy the Unforeseeable Financial Emergency. If, subject to the sole
discretion  of the  Committee,  the petition for a suspension  and/or  payout is
approved,  suspension shall take effect upon the date of approval and any payout
shall be made within 60 days of the date of approval.  The payment of any amount
under this Section 4.3 shall not be subject to the Deduction Limitation.

     4.4 WITHDRAWAL  ELECTION. A Participant may elect, at any time, to withdraw
all of his or her Account  Balance,  less a withdrawal  penalty  equal to 10% of
such amount (the net amount  shall be referred to as the  "Withdrawal  Amount").
This election can be made at any time, before or after  Retirement,  Disability,
death or  Termination  of  Employment,  and whether or not the  Participant  (or
Beneficiary) is in the process of being paid pursuant to an installment  payment
schedule.  If made  before  Retirement,  Disability  or death,  a  Participant's
Withdrawal Amount shall be his or her Account Balance calculated as if there had
occurred a Termination  of Employment as of the day of the election.  No partial
withdrawals of the Withdrawal  Amount shall be allowed.  The  Participant  shall
make this  election  by  giving  the  Committee  advance  written  notice of the
election  in a  form  determined  from  time  to  time  by  the  Committee.  The
Participant  shall be paid the  Withdrawal  Amount  within 60 days of his or her
election. Once the Withdrawal Amount is paid, the Participant's participation in
the Plan shall  terminate,  the  Participant's  Unvested Accrued Amounts will be
forfeited and the  Participant  shall not be eligible to participate in the Plan
in the future. The payment of this Withdrawal Amount shall not be subject to the
Deduction Limitation.

     5.1 RETIREMENT BENEFIT.  Subject to the Deduction Limitation, a Participant
who Retires shall receive, as a Retirement Benefit, his or her Account Balance.

5.2      PAYMENT OF RETIREMENT BENEFIT. A Participant, in connection with his or
         her  commencement  of  participation  in the  Plan,  shall  elect on an
         Election  Form to  receive  the  Retirement  Benefit  in a lump  sum or
         pursuant to a Monthly  Installment Method of 60, 120 or 180 months. The
         Participant  may  annually  change his or her  election to an allowable
         alternative  payout  period by  submitting a new  Election  Form to the
         Committee, provided that any such Election Form is submitted at least 2
         years  prior to the  Participant's  Retirement  and is  accepted by the
         Committee  in its sole  discretion.  The  Election  Form most  recently
         accepted by the  Committee  shall  govern the payout of the  Retirement
         Benefit.  If a  Participant  does not make any election with respect to
         the payment of the Retirement Benefit, such benefit shall be payable in
         a lump

         sum. The lump sum payment shall be made, or installment  payments shall
         commence, no later than 60 days after the date the Participant Retires.
         Notwithstanding the foregoing,  if the Company enters into a consulting
         arrangement with a Participant following the Participant's  Retirement,
         the  payment  of the  Retirement  Benefit  shall be  delayed  and shall
         commence  no  later  than  60  days  after  the  date  the   consulting
         arrangement  terminates.  Any  payment  made  shall be  subject  to the
         Deduction Limitation.

5.3      DEATH PRIOR TO COMPLETION OF RETIREMENT  BENEFIT. If a Participant dies
         after Retirement but before the Retirement Benefit is paid in full, the
         Participant's  unpaid  Retirement  Benefit  payments shall continue and
         shall be paid to the  Participant's  Beneficiary (a) over the remaining
         number of months  and in the same  amounts as that  benefit  would have
         been paid to the Participant had the Participant  survived, or (b) in a
         lump sum,  if  requested  by the  Beneficiary  and  allowed in the sole
         discretion of the Committee,  that is equal to the Participant's unpaid
         remaining Account Balance.

                         Pre-Retirement Survivor Benefit

6.1      PRE-RETIREMENT  SURVIVOR BENEFIT.  Subject to the Deduction Limitation,
         the Participant's  Beneficiary shall receive a Pre-Retirement  Survivor
         Benefit equal to the  Participant's  Account Balance if the Participant
         dies before he or she Retires,  experiences a Termination of Employment
         or suffers a Disability.

     6.2 PAYMENT OF PRE-RETIREMENT SURVIVOR BENEFIT. The Pre-Retirement Survivor
Benefit  shall be paid in the same manner and at the same time as  specified  in
the election made by the Participant pursuant to Section 5.2.

         Participant shall receive a Termination  Benefit,  which shall be equal
         to the Participant's Account Balance (i.e.,  determined based on Vested
         Company   Matching   Contributions   and  Vested  Company   Restoration
         Contributions) if a Participant experiences a Termination of Employment
         prior to his or her Retirement, death or Disability.

7.2      PAYMENT OF TERMINATION  BENEFIT.  The Termination Benefit shall be paid
         in a lump  sum  within  60  days  of  the  Termination  of  Employment.
         Notwithstanding the foregoing,  a Participant may elect either (i) upon
         his  election to  participate  in the Plan or (ii) at any time at least
         two years prior to Termination of Employment to receive the Termination
         Benefit in three annual installments.
         Any payment made shall be subject to the Deduction Limitation.

                          Disability Waiver and Benefit

8.1      DISABILITY WAIVER.

     (a) WAIVER OF DEFERRAL. A Participant who is determined by the Committee to
be  suffering  ------------------  from  a  Disability  shall  be  excused  from
fulfilling  that portion of the Annual  Deferral  Amount  commitment  that would
otherwise  have been  withheld  from a  Participant's  Base Annual Salary and/or
Annual  Bonus for the Plan Year during  which the  Participant  first  suffers a
Disability.  During  the  period of  Disability,  the  Participant  shall not be
allowed to make any  additional  deferral  elections,  but will  continue  to be
considered a Participant  for all other  purposes of this Plan.  Notwithstanding
the  foregoing,  if the Disability is determined by the Committee to be expected
to be of a short term duration,  the Annual Deferral Amount shall continue to be
withheld from a Participant's Base Annual Salary and/or Annual Bonus.

         (b)      RETURN TO WORK. If a Participant returns to employment with an
                  Employer, after a Disability ceases, the Participant may elect
                  to defer an Annual Deferral Amount for the Plan Year following
                  his or her return to  employment or service and for every Plan
                  Year thereafter while a Participant in the Plan; provided such
                  deferral  elections are otherwise allowed and an Election Form
                  is delivered to and  accepted by the  Committee  for each such
                  election in accordance with Section 3.3 above.

8.2      CONTINUED  ELIGIBILITY;  DISABILITY BENEFIT. A Participant  suffering a
         Disability shall, for benefit purposes under this Plan,  continue to be
         considered  to be  employed,  and shall be  eligible  for the  benefits
         provided for in Articles 4, 5, 6 or 7 in accordance with the provisions
         of those Articles.  Notwithstanding the above, the Committee shall have
         the right to, in its sole and absolute  discretion  and for purposes of
         this Plan only, and must in the case of a Participant  who is otherwise
         eligible  to  Retire,  deem  the  Participant  to  have  experienced  a
         Termination  of  Employment,  or in the  case of a  Participant  who is
         eligible to Retire,  to have Retired,  at any time (or in the case of a
         Participant who is eligible to Retire,  as soon as  practicable)  after
         such Participant is determined to be permanently disabled (i) under the
         Participant  Employer's  long-term  disability plan (or would have been
         determined to be  permanently  disabled had he or she  participated  in
         that plan),  or (ii) if such a plan does not exist, by the Committee in
         its sole  discretion,  in which case the  Participant  shall  receive a
         Disability  Benefit equal to his or her Account Balance at the time the
         Committee's determination.  The Disability Benefit shall be paid in the
         same manner and at the same time as specified  in the election  made by
         the  Participant  pursuant to Section 5.2,  unless the Committee in its
         sole discretion  elects at any time to pay such amount or any remaining
         amount in a lump sum payment.  Any payment made shall be subject to the
         Deduction Limitation.

                             Beneficiary Designation

     9.1  BENEFICIARY.  Each  Participant  shall have the right, at any time, to
designate his or her  Beneficiary(ies)  (both primary as well as  contingent) to
receive any benefits payable under the Plan to a beneficiary upon the death of a
Participant. The Beneficiary designated under this

         Plan may be the same as or different from the  Beneficiary  designation
         under  any  other  plan  of  an  Employer  in  which  the   Participant
         participates.

9.2      BENEFICIARY  DESIGNATION;  CHANGE; SPOUSAL CONSENT. A Participant shall
         designate  his  or  her  Beneficiary  by  completing  and  signing  the
         Beneficiary  Designation Form, and returning it to the Committee or its
         designated  agent.  A  Participant  shall  have the  right to  change a
         Beneficiary  by  completing,  signing and otherwise  complying with the
         terms of the Beneficiary Designation Form and the Committee's rules and
         procedures,  as in effect from time to time. If the  Participant  names
         someone other than his or her spouse as a Beneficiary for more than 50%
         of  the  Participant's   benefits,  a  spousal  consent,  in  the  form
         designated  by the  Committee,  must be  signed  by that  Participant's
         spouse  and  returned  to the  Committee.  Upon the  acceptance  by the
         Committee  of a  new  Beneficiary  Designation  Form,  all  Beneficiary
         designations  previously filed shall be cancelled.  The Committee shall
         be entitled to rely on the last  Beneficiary  Designation Form filed by
         the  Participant  and  accepted  by the  Committee  prior to his or her
         death.

9.3      ACKNOWLEDGMENT.   No   designation   or  change  in  designation  of  a
         Beneficiary   shall  be   effective   until   received,   accepted  and
         acknowledged in writing by the Committee or its designated agent.

9.4      NO  BENEFICIARY  DESIGNATION.  If a  Participant  fails to  designate a
         Beneficiary  as provided in Sections  9.1, 9.2 and 9.3 above or, if all
         designated  Beneficiaries  predecease  the  Participant or die prior to
         complete   distribution  of  the  Participant's   benefits,   then  the
         Participant's  designated  Beneficiary shall be deemed to be his or her
         surviving  spouse.  If the  Participant  has no surviving  spouse,  the
         benefits  remaining under the Plan to be paid to a Beneficiary shall be
         payable to the executor or personal representative of the Participant's
         estate.

9.5      DOUBT  AS TO  BENEFICIARY.  If the  Committee  has any  doubt as to the
         proper  Beneficiary  to receive  payments  pursuant  to this Plan,  the
         Committee shall have the right, exercisable in its discretion, to cause
         the Participant's  Employer to withhold such payments until this matter
         is resolved to the Committee's satisfaction.

9.6      DISCHARGE OF  OBLIGATIONS.  The payment of benefits under the Plan to a
         Beneficiary  shall fully and  completely  discharge  the  Company,  all
         Employers and the  Committee  from all further  obligations  under this
         Plan with  respect  to the  Participant,  and that  Participant's  Plan
         Agreement shall terminate upon such full payment of benefits.

                                Leave of Absence

10.1     PAID  LEAVE  OF  ABSENCE.   If  a  Participant  is  authorized  by  the
         Participant's  Employer  for any reason to take a paid leave of absence
         from the employment of the Employer,  the Participant shall continue to
         be considered  employed by the Employer and the Annual  Deferral Amount
         shall  continue  to be  withheld  during  such paid leave of absence in
         accordance with Section 3.3.

10.2     UNPAID  LEAVE  OF  ABSENCE.  If a  Participant  is  authorized  by  the
         Participant's  Employer  for any  reason  to take an  unpaid  leave  of
         absence from the  employment of the  Employer,  the  Participant  shall
         continue to be considered  employed by the Employer and the Participant
         shall be excused  from making  deferrals  until the earlier of the date
         the leave of absence expires or

         the  Participant  returns  to  a  paid  employment  status.  Upon  such
         expiration or return,  deferrals shall resume for the remaining portion
         of the Plan Year in which the expiration or return occurs, based on the
         deferral election,  if any, made for that Plan Year. If no election was
         made for that Plan Year, no deferral shall be withheld.

                                   ARTICLE 11
                     Termination, Amendment or Modification

11.1     TERMINATION.  Each Employer reserves the right to terminate the Plan at
         any time with respect to any or all of its  participating  Employees by
         the actions of its board of directors. Upon the termination of the Plan
         with  respect to any  Employer,  the Plan  Agreements  of the  affected
         Participants  who are employed by that  Employer  shall  terminate  and
         their  Account  Balance,  determined  as  if  they  had  experienced  a
         Termination of Employment on the date of Plan  termination  or, if Plan
         termination occurs after the date upon which a Participant was eligible
         to Retire,  then with respect to that  Participant  as if he or she had
         Retired  on  the  date  of  Plan  termination,  shall  be  paid  to the
         Participants as follows:  Prior to a Change in Control,  if the Plan is
         terminated with respect to all of its  Participants,  an Employer shall
         have  the  right,  in its  sole  discretion,  and  notwithstanding  any
         elections made by the  Participant,  to pay such benefits in a lump sum
         or pursuant  to a Monthly  Installment  Method of up to 15 years,  with
         amounts credited and debited during the installment  period as provided
         herein.  If the Plan is terminated with respect to less than all of its
         Participants,  an Employer  shall be required to pay such benefits in a
         lump sum. After a Change in Control,  the Employer shall be required to
         pay such benefits in a lump sum. The  termination of the Plan shall not
         adversely affect any Participant or Beneficiary who has become entitled
         to the  payment  of any  benefits  under  the  Plan  as of the  date of
         termination;  provided however,  that the Employer shall have the right
         to accelerate  installment  payments by paying the Account Balance in a
         lump sum or  pursuant  to a  Monthly  Installment  Method  using  fewer
         months.

11.2     AMENDMENT.  Any Employer may, at any time,  amend or modify the Plan in
         whole or in part with  respect to that  Employer  by the actions of its
         board  of   directors;   provided,   however,   that  no  amendment  or
         modification  shall be effective to decrease or restrict the value of a
         Participant's Account Balance in existence at the time the amendment or
         modification is made,  calculated as if the Participant had experienced
         a Termination  of Employment as of the effective  date of the amendment
         or modification,  or, if the amendment or modification occurs after the
         date upon which the Participant was eligible to Retire, the Participant
         had Retired as of the effective date of the amendment or  modification.
         The  amendment  or  modification  of the  Plan  shall  not  affect  any
         Participant  or Beneficiary  who has become  entitled to the payment of
         benefits   under  the  Plan  as  of  the  date  of  the   amendment  or
         modification; provided, however, that the Employer shall have the right
         to accelerate  installment  payments by paying the Account Balance in a
         lump sum or  pursuant  to a  Monthly  Installment  Method  using  fewer
         months.

11.3     PLAN AGREEMENT. Despite the provisions of Sections 11.1 and 11.2 above,
         if a Participant's Plan Agreement contains benefits or limitations that
         are not in this Plan document, the Employer may only amend or terminate
         such provisions with the consent of the Participant.

11.4     EFFECT OF PAYMENT.  The full payment of the  applicable  benefit  under
         Section  4.4 or  Articles  5, 6, 7 or 8 of the  Plan  shall  completely
         discharge all  obligations  to a Participant  and his or her designated
         Beneficiaries  under  this Plan and the  Participant's  Plan  Agreement
         shall terminate.

         after such notice was received by the  Claimant.  All other claims must

                  or in part, to the  Claimant's  requested  determination,  and
                  such  notice  must  set  forth in a  manner  calculated  to be

     (ii) specific  reference(s) to pertinent  provisions of the Plan upon which
such denial was based;

         Committee's  decision must be rendered within 120 days after such date.

                                      Trust

15.1     ESTABLISHMENT  OF THE TRUST. The Company shall establish the Trust, and
         the each Employer  shall at least  annually  transfer over to the Trust
         such assets as the Employer  determines are necessary to provide,  on a
         present value basis, for its future liabilities created with respect to
         all Annual  Deferral  Amounts,  Company  Matching  Amounts  and Company
         Restoration  Amounts for such Employer's  Participants  for all periods
         prior  to the  transfer,  as  well as the  credits  and  debits  to the
         Participants'  Account Balance (and Unvested  Accrued  Amounts) for all
         periods prior to the transfer,  taking into  consideration the value of

         shall  govern  the  rights  of  the  Employers,  Participants  and  the
         creditors of the Employers to the assets transferred to the Trust. Each
         Employer shall at all times remain liable to carry out its  obligations
         under the Plan.

15.3     DISTRIBUTIONS  FROM THE TRUST.  Each Employer's  obligations  under the
         Plan may be  satisfied  with Trust assets  distributed  pursuant to the
         terms  of the  Trust,  and  any  such  distribution  shall  reduce  the
         Employer's obligations under this Plan.

16.1     UNSECURED  GENERAL  CREDITOR.  Participants  and  their  Beneficiaries,
         heirs,  successors and assigns shall have no legal or equitable rights,
         interests  or claims in any  property  or  assets of an  Employer.  For
         purposes of the payment of benefits  under this Plan, any and all of an
         Employer's  assets  shall  be,  and  remain,  the  general,   unpledged
         unrestricted assets of the Employer. An Employer's obligation under the
         Plan shall be merely that of an unfunded and  unsecured  promise to pay
         money in the future.

16.2     EMPLOYER'S  LIABILITY.  An  Employer's  liability  for the  payment  of
         benefits shall be defined only by the Plan and the Plan  Agreement,  as
         entered into between the Employer and a Participant.  An Employer shall
         have no obligation to a Participant  under the Plan except as expressly
         provided in the Plan and his or her Plan Agreement.

16.3     NONASSIGNABILITY. Neither a Participant nor any other person shall have
         any right to  commute,  sell,  assign,  transfer,  pledge,  anticipate,
         mortgage or  otherwise  encumber,  transfer,  hypothecate,  alienate or
         convey in advance  of actual  receipt,  the  amounts,  if any,  payable
         hereunder,  or any part thereof, which are, and all rights to which are
         expressly  declared to be,  unassignable and  non-transferable,  except
         that the foregoing  shall not apply to any family  support  obligations
         set forth in a court order. No part of the amounts payable shall, prior
         to actual payment,  be subject to seizure,  attachment,  garnishment or
         sequestration  for the  payment  of any  debts,  judgments,  alimony or
         separate  maintenance owed by a Participant or any other person, nor be
         transferable by operation of law in the event of a Participant's or any
         other person's bankruptcy or insolvency.

     16.4 NOT A CONTRACT OF  EMPLOYMENT.  The terms and  conditions of this Plan
shall not be deemed to  ----------------------------  constitute  a contract  of
employment  between  the  Company  or any  Employer  and the  Participant.  Such
employment is hereby  acknowledged  to be an "at will"  employment  relationship
that can be terminated at any time for any reason, or no reason, with or without
cause,  and with or  without  notice,  unless  expressly  provided  in a written

discharge the Participant at any time.

16.5     FURNISHING  INFORMATION.  A Participant or his or her Beneficiary  will

         singular or in the plural,  they shall be construed as though they were
         used in the  plural or the  singular,  as the case may be, in all cases
         where they would so apply.

16.7     CAPTIONS. The captions of the articles, sections and paragraphs of this
         Plan are for  convenience  only and shall  not  control  or affect  the

16.11    SPOUSE'S  INTEREST.  The interest in the benefits hereunder of a spouse
         of  a  Participant   who  has   predeceased   the   Participant   shall
         automatically  pass to the Participant and shall not be transferable by
         such spouse in any manner,  including  but not limited to such spouse's
         will,  nor  shall  such  interest  pass  under  the  laws of  intestate
         succession.

16.12    VALIDITY.  In case any  provision  of this  Plan  shall be  illegal  or
         invalid for any reason,  said  illegality or invalidly shall not affect
         the  remaining  parts  hereof,  but this Plan  shall be  construed  and
         enforced  as if such  illegal  or  invalid  provision  had  never  been
         inserted herein.

16.13    INCOMPETENT.  If the  Committee  determines  in its  discretion  that a
         benefit  under  this Plan is to be paid to a minor,  a person  declared
         incompetent  or to a person  incapable of handling the  disposition  of
         that  person's  property,  the  Committee  may  direct  payment of such
         benefit to the guardian, legal representative or person having the care
         and  custody  of such  minor,  incompetent  or  incapable  person.  The
         Committee  may require proof of minority,  incompetency,  incapacity or
         guardianship,  as it may deem appropriate  prior to distribution of the
         benefit. Any payment of a benefit shall be a payment for the account of
         the Participant and the Participant's Beneficiary,  as the case may be,
         and shall be a complete  discharge of any liability  under the Plan for
         such payment amount.

16.14    COURT ORDER. The Committee is authorized to make any payments  directed
         by court  order in any  action in which the Plan or the  Committee  has
         been named as a party. In addition, if a court determines that a spouse
         or former  spouse of a  Participant  has an interest in the Plan as the
         result of a property  settlement or otherwise,  the  Committee,  in its
         sole  discretion,  shall have the right,  notwithstanding  any election
         made by a Participant, to immediately distribute the spouse's or former
         spouse's interest in the Plan to that spouse or former spouse.

16.15    DISTRIBUTION IN THE EVENT OF TAXATION.

     (a) IN GENERAL.  If, for any reason,  all or any portion of a Participant's
benefit under this ----------  Plan becomes taxable to the Participant  prior to
receipt, a Participant may petition the Committee before a Change in Control, or
the trustee of the Trust after a Change in Control,  for a distribution  of that
portion of his or her benefit that has become taxable.  Upon the grant of such a
petition, which grant shall not be unreasonably withheld (and, after a Change in
Control,  shall be granted),  a Participant's  Employer shall  distribute to the
Participant  immediately  available  funds in an  amount  equal  to the  taxable
portion of his or her benefit  (which  amount  shall not exceed a  Participant's
Account Balance under the Plan).  If the petition is granted,  the tax liability
distribution  shall be made  within 90 days of the date  when the  Participant's
petition is granted. Such a distribution shall affect and reduce the benefits to
be paid under this Plan.

         (b)      TRUST.  If the Trust  terminates  in  accordance  with Section
                  3.7(e) of the  Trust and  benefits  are  distributed  from the
                  Trust to a Participant  in accordance  with that Section,  the
                  Participant's benefits under this Plan shall be reduced to the
                  extent of such distributions.

     16.16 LEGAL FEES TO ENFORCE RIGHTS AFTER CHANGE IN CONTROL. The Company and
each  Employer is aware that upon the  occurrence  of a Change in  Control,  the
Board or the board of directors of the Employer (which might then be composed of
new members) or a shareholder of the

         Company or the  Employer,  or of any successor  corporation  might then
         cause or attempt to cause the Company,  the Employer or such  successor
         to refuse to comply with its obligations under the Plan and might cause
         or attempt to cause the Company or the  Employer to  institute,  or may
         institute,   litigation  seeking  to  deny  Participants  the  benefits
         intended  under the Plan.  In these  circumstances,  the purpose of the
         Plan  could be  frustrated.  Accordingly,  if,  following  a Change  in
         Control,  it should  appear to any  Participant  that the Company,  its
         Employer or any successor  corporation has failed to comply with any of
         its obligations  under the Plan or any agreement  thereunder or, if the
         Company,  such Employer or any other person takes any action to declare
         the Plan void or  unenforceable  or institutes  any litigation or other
         legal  action  designed  to  deny,  diminish  or to  recover  from  any
         Participant the benefits intended to be provided,  then the Company and
         the Employer  irrevocably  authorize such Participant to retain counsel
         of his or her choice at the  expense of the  Company  and the  Employer
         (who  shall  be  jointly  and  severally   liable)  to  represent  such
         Participant  in  connection  with  the  initiation  or  defense  of any
         litigation  or other legal  action,  whether by or against the Company,
         the  Employer or any  director,  officer,  shareholder  or other person
         affiliated with the Company,  the Employer or any successor  thereto in
         any jurisdiction.

Participant's SERP Benefit  (calculated based on the Assumed Interest Rate(s) in
effect during the period since such prior payments were made) to the Participant
were to be paid out in  quarterly  installments  at the  same  dates as the SERP

                      Participant  has been  employed  by one or more  Employers
                      through  such date plus any  additional  Years of  Service
                      credited to such Participant under Section 3.2;

             (ii)     in the  case of a  Participant  not  named  on  Exhibit  A

             of hiring and each  anniversary  thereof  (subject to adjustment to
             reflect leaves of absence),  in the case of a Participant  named on
             Exhibit A, or the date of initial  participation in the Plan and on
             each  anniversary  thereof (subject to adjustment to reflect leaves
             of absence),  in the case of other  Participants.  In the case of a
             Participant who has suffered a Disability but thereafter returns to
             service or becomes  reemployed  by an Employer  promptly  after the
             Disability  ended,  the period(s) of such Disability in the year in
             which the  Disability  began  and the year in which the  Disability
             ended will be counted as  employment  solely for  purposes  of this
             definition,  but any other period (I.E.  full years) of  Disability
             shall not count as employment and therefore shall not be treated as
             Years  of  Service.  In  the  case  of  a  Participant  who  has  a
             Termination  of  Employment  for any  reason  other  than  death or
             Disability  following a Change in Control,  (i) if the  Participant
             was not employed for a full 365- (or 366-) day period that includes
             the date of the Change in Control, such Participant shall be deemed
             to have  completed a full Year of Service in respect of that period
             which includes the Change in Control,  and (ii), if the Participant
             qualifies  for  payment of his or her SERP  Benefit  under  Section
             4.1(b) or under Section 4.1(a) within six years after the Change in
             Control, such Participant shall be credited with an additional Year
             of  Service  as of  the  date  immediately  prior  to  his  or  her
             Termination of Employment.  Except as provided in this  definition,
             no  partial  year  of  employment  shall  be  counted  as a Year of
             Service.  A Participant's  paid leave of absence or unpaid leave of
             absence  for 90  days  or  less  shall  constitute  employment  for
             purposes of this  definition,  but a Participant's  unpaid leave of
             absence for more than 90 days shall not  constitute  employment for
             purposes of this definition.

             payment of a Participant's  Vested SERP Benefit,  a Participant may
             be  credited  with  additional   "deemed"  Years  of  Service,   if
             recommended  by  the  Plan   Administrator   and  approved  by  the
             Compensation  Committee.  In  no  event  may  the  number  of  such
             additional  "deemed"  Years  of  Service  exceed  five  for any one
             Participant.

                                    BENEFITS

4.1          ELIGIBILITY FOR BENEFITS.

             (a)      BENEFIT UPON  RETIREMENT OR  DISABILITY.  If a Participant
                      Retires or suffers a Disability,  the Participant shall be
                      entitled to payment of his or her Vested  SERP  Benefit in
                      quarterly  installments to the Participant and,  following
                      Participant's death, to his or her Beneficiary(ies), for a
                      period of 15 years. Payment of benefits under this Section
                      4.1(a)  shall  commence  on the  first  day  of  the  next
                      calendar  quarter  that begins at least 30 days after such
                      Retirement  or 30  days  after  the  Plan  Administrator's
                      receipt  of  written  proof  or   determination   of  such
                      Participant's Disability.

             (b)      BENEFIT UPON TERMINATION FOLLOWING A CHANGE IN CONTROL. If
                      a Participant  has a Termination of Employment  within six
                      years  following  a  Change  in  Control,   other  than  a
                      Retirement or termination  due to death or Disability,  he
                      or she shall be paid,  as a  lump-sum  cash  payment,  the
                      Present Value of his or her Vested SERP Benefit  within 15
                      days  after  such  Termination  of  Employment,   in  full
                      settlement of the Participant's rights under the Plan..

     (c)  SURVIVORS'  BENEFIT.  If a  Participant  dies  prior  to  his  or  her
Termination  of  Employment  ------------------  and not  while  Participant  is
receiving  benefits under Section 4.1(a) due to a Disability,  the Participant's
Beneficiary shall be entitled to receive the  Participant's  Vested SERP Benefit
in  the  form  of  a  Preretirement  Survivor  Benefit,   payable  in  quarterly
installments  for a period of 15 years.  Payments of benefits under this Section
4.1(c) shall commence on the first day of the next calendar  quarter that begins
at least 60 days after the Plan Administrator has received written proof of such
Participant's death. The foregoing notwithstanding,  a Beneficiary then entitled
to  receive a SERP  Benefit  may  petition  the Plan  Administrator  in  writing
requesting  payment  of such SERP  Benefit in a  lump-sum  due to the  financial
hardship of the Beneficiary or his or her dependents, stating with particularity
the reasons giving rise to constituting  such hardship.  The Plan  Administrator
may approve or disapprove  such request,  in its sole  discretion.  If approved,
such Beneficiary shall be paid, as a lump-sum cash payment, the Present Value of
such SERP Benefit as of the payment date specified by the Plan Administrator, in
full settlement of the Beneficiary's rights under the Plan.

     (d) BENEFIT UPON OTHER  TERMINATION OF EMPLOYMENT.  If a Participant  has a
Termination  --------------------------------------------  of  Employment  which
does not give rise to payment of benefits  under Section 4.1(a) or (b) and which
is not due to death and is not a  termination  by the  Company  for  Cause,  the
Participant  shall be entitled  to payment of his or her Vested SERP  Benefit in
quarterly installments to the Participant and, following Participant's death, to
his or her Beneficiary(ies), for a period of 15 years. Payment of benefits under
this  Section  4.1(d)  shall  commence on the later of the first day of the next
calendar  quarter  that  begins  at  least 90 days  after  such  Termination  of
Employment  or the next calendar  quarter that begins at or after  Participant's
completion of ten Years of Service; provided, however,

                      that  the  Plan  Administrator  may  elect  to  pay to the
                      Participant  (or,  following  his  or  her  death,  to the
                      Participant's  Beneficiary(ies))  a lump-sum cash payment,
                      the Present  Value of such Vested SERP Benefit  determined
                      as of the  date  of  Termination  of  Employment,  in full
                      settlement    of    the     Participant's     (and    such
                      Beneficiary's(ies')  rights under the Plan.  Such lump-sum
                      cash  payment  shall be made on the  first day of the next
                      calendar  quarter  that begins at least 90 days after such
                      Termination of Employment.

     (e)  CIRCUMSTANCES  IN WHICH NO BENEFIT IS  PAYABLE.  Upon a  Participant's
Termination  of  --------------------------------------------   Employment,  the
Participant  (including his or her  Beneficiaries)  will forfeit all rights to a
SERP Benefit if such SERP Benefit did not become  Vested prior to or as a result
of such Termination of Employment.  In addition, in the event of a Participant's
Termination  of  Employment  by the  Company  for Cause which both is prior to a
Change  in  Control  and does  not  qualify  as a  Retirement,  the  Participant
(including his or her  Beneficiaries)  will forfeit all rights to a SERP Benefit
whether or not such SERP Benefit had become Vested.

     4.2 REEMPLOYMENT OF PARTICIPANT WHO HAS RECEIVED BENEFITS. Other provisions
of the Plan  notwithstanding,  if a Participant who has received payments of his
or her  SERP  Benefit  thereafter  becomes  reemployed  by any  Employer  (I.E.,
following the end of a Disability or as a result of being rehired),  payments of
such SERP Benefit will be suspended for so long as the Participant is thereafter
employed  by any  Employer.  Upon a  subsequent  Termination  of  Employment  or
Disability,  if the Participant  did not accrue further  benefits under the Plan
following such reemployment or if such subsequent Termination of Employment does
not give  rise to  payment  of  benefits  under  the Plan,  the  payment  of the
Participant's  previous  Vested SERP Benefit shall resume in accordance with its
original  terms (for the remaining  period such Vested SERP Benefit is payable).
Upon a subsequent  Termination of Employment or Disability,  if the  Participant
accrued further benefits under the Plan following such  reemployment and if such
subsequent  Termination of Employment or Disability gives rise to benefits under
Section 4.1, the  Participant's  SERP Benefit shall become payable in accordance
with Section 4.1;  provided,  however,  that such  Participant's  Final  Average
Compensation  for purposes of calculating  such SERP Benefit shall be the higher
of his or her Final Average  Compensation at the date of the latest  Termination
of  Employment  or the Final Average  Compensation  as previously  calculated in
determining his or her previously paid SERP Benefit.

4.3          ALTERNATIVE PAYOUTS.

             (a)      LUMP SUM. If a  Participant's  Vested SERP  Benefit  under
                      this Plan at the time he or she, or his or her Beneficiary
                      (whether  primary  or  contingent),  becomes  eligible  to
                      receive a distribution  under this Plan, when expressed on
                      a Present Value basis as a lump sum, is less than $25,000,
                      the Plan  Administrator,  in its sole discretion,  may pay
                      that  benefit  in a  lump  sum at the  time  that  benefit
                      payments would otherwise commence.

     (b) WITHDRAWAL  ELECTION.  A Participant or his or her Beneficiary,  as the
case  may  be,  may  -------------------  elect,  at any  time  after  he or she
commences  to  receive  benefits  payments  under this  Plan,  to receive  those
payments  in a lump  sum,  based on the  Present  Value of his or her  remaining
Vested SERP  Benefits  less a 10% penalty (as  described  below) (the net amount
shall  be  referred  to as the  "Benefit  Amount").  No  election  to  partially
accelerate  benefits shall be allowed.  The Participant shall make this election
by giving the Plan  Administrator  advance  written  notice of the election in a
form determined from time to time by the Plan  Administrator.  The penalty shall
be equal to 10% of the Participant's remaining Vested SERP Benefits,  determined
on a Present Value basis. The Participant

                      shall be paid the Benefit  Amount within 60 days after his
                      or her  election.  Once the  Benefit  Amount is paid,  the
                      Participant's  participation  in the Plan shall  terminate
                      and the  Participant  shall not be eligible to participate
                      in the Plan in the future.

     4.4  WITHHOLDING  AND PAYROLL TAXES.  The Employers shall withhold from any
and all  benefits  paid  -----------------------------  under this Article 4 all
federal,  state and local  income,  employment  and other  taxes  required to be
withheld by the Employers in connection with the benefits hereunder,  in amounts
to be determined in the sole discretion of the Employers.

               TERMINATION, AMENDMENT OR MODIFICATION OF THE PLAN

5.1          TERMINATION. Each Employer reserves the right to terminate the Plan
             at any time with  respect  to its  participating  employees  by the
             action of its board of directors.  A termination  of the Plan shall
             have the effect of terminating further accruals of Years of Service
             that would accrue (assuming the Participant's continued employment)
             more  than  six  months  after  the  termination  of  the  Plan.  A
             termination  of the Plan shall not otherwise  materially  adversely
             affect the a - Participant's  SERP Benefit or rights under the Plan
             or, in the case of a  Beneficiary  who has become  entitled  to the
             payment of benefits  under the Plan as of the date of  termination,
             the rights of such Beneficiary under the Plan.

5.2          AMENDMENT.  Any Employer may, at any time, amend or modify the Plan
             in whole or in part with respect to its participating employees and
             former  employees  by  the  actions  of  its  board  of  directors;
             provided,  however,  that no  amendment  or  modification  shall be
             effective   to   decrease   or   materially   adversely   affect  a
             Participant's SERP Benefit or rights under the Plan or, in the case
             of a Beneficiary who has become entitled to the payment of benefits
             under the Plan as of the date of  termination,  the  rights of such
             Beneficiary under the Plan.

     5.3  TERMINATION  OF  PLAN  AGREEMENT.   Absent  the  earlier  termination,
modification  or amendment of the Plan,  the Plan  Agreement of any  Participant
shall  terminate upon the full payment of the applicable  Vested SERP Benefit as
provided under Article 4.


                                    ARTICLE 6
                          OTHER BENEFITS AND AGREEMENTS

             The  benefits  provided  for a  Participant  under this Plan are in
addition to any other  benefits  available to such  Participant  under any other
plan or program for employees of the  Employers.  The Plan shall  supplement and

             Compensation   Committee   shall  appoint.   Members  of  the  Plan

                                CLAIMS PROCEDURES

8.1          PRESENTATION OF CLAIM. Any Participant or Beneficiary of a deceased
             Participant  (such  Participant  or  Beneficiary  being referred to
             below as a  "Claimant")  may  deliver to the Plan  Administrator  a
             written  claim for a  determination  with  respect  to the  amounts
             distributable  to such  Claimant  from  the  Plan.  If such a claim
             relates to the contents of a notice  received by the Claimant,  the
             claim must be made within 60 days after such notice was received by
             the  Claimant.   The  claim  must  state  with   particularity  the
             determination  desired by the  Claimant.  All other  claims must be
             made within 180 days of the date on which the event that caused the
             claim to arise  occurred.  The claim must state with  particularity
             the determination desired by the Claimant.

     8.2  NOTIFICATION  OF DECISION.  The Plan  Administrator  shall  consider a
Claimant's  claim within a  ------------------------  reasonable time, and shall
notify the Claimant in writing:

     (i) that the Claimant's requested determination has been made, and that the
claim has been allowed in full; or

                      (ii)    that  the  Plan   Administrator   has   reached  a
                              conclusion  contrary,  in whole or in part, to the
                              Claimant's  requested   determination,   and  such
                              notice must set forth in a manner calculated to be
                              understood by the Claimant:

     (1) the specific reason(s) for the denial of the claim, or any part of it;

     (2) specific  reference(s)  to pertinent  provisions of the Plan upon which
such denial was based;

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

     (4) an explanation  of the claim review  procedure set forth in Section 8.3
below.

8.3          REVIEW OF A DENIED CLAIM.  Within 60 days after  receiving a notice
             from the Plan  Administrator that a claim has been denied, in whole
             or  in  part,  a  Claimant  (or  the  Claimant's   duly  authorized
             representative)  may file  with the Plan  Administrator  a  written
             request  for a review of the denial of the claim.  Thereafter,  but
             not  later  than 30 days  after the  review  procedure  began,  the
             Claimant (or the Claimant's duly authorized representative):

                      (i)     may review pertinent documents;

     (ii) may submit written comments or other documents; and/or

     (iii) may  request a  hearing,  which the Plan  Administrator,  in its sole
discretion, may grant.

     8.4 DECISION ON REVIEW. The Plan Administrator shall render its decision on
review promptly,  and ------------------ not later than 60 days after the filing
of a written request for review of the denial, unless a hearing is held or other
special   circumstances   require  additional  time,  in  which  case  the  Plan
Administrator's  decision must be rendered within 120 days after such date. Such
decision  must  be  written  in a  manner  calculated  to be  understood  by the
Claimant, and it must contain:

                      (i)     specific reasons for the decision;

     (ii) specific  reference(s) to the pertinent Plan provisions upon which the
decision was based; and

     (iii) such other matters as the Plan Administrator deems relevant.

8.5          LEGAL ACTION. A Claimant's compliance with the foregoing provisions
             of this Article 8 is a mandatory prerequisite to a Claimant's right
             to commence any legal action with respect to any claim for benefits
             under this Plan.  Except to the extent  otherwise  required by law,
             any dispute or controversy  arising under the Plan or in connection
             with any Plan Agreement shall be settled exclusively by arbitration
             in Las Vegas,  Nevada, in accordance with the rules of the American
             Arbitration  Association  in  effect at the time of  submission  to
             arbitration.  Judgment may be entered on the arbitrators'  award in
             any court having jurisdiction.

                             BENEFICIARY DESIGNATION

9.1          BENEFICIARY. Each Participant shall have the right, at any time, to
             designate  his or her  Beneficiary(ies)  (both  primary  as well as
             contingent)  to receive any  benefits  payable  under the Plan to a
             beneficiary  upon  the  death  of a  Participant.  The  Beneficiary
             designated under this Plan may be the same as or different from the
             Beneficiary  designation  under any other  plan of an  Employer  in
             which the Participant participates.

     9.2 BENEFICIARY  DESIGNATION;  CHANGE; SPOUSAL CONSENT. A Participant shall
designate    his   or    her    ------------------------------------------------
Beneficiary  by completing  and signing the  Beneficiary  Designation  Form, and
returning it to the Plan  Administrator  or its designated  agent. A Participant
shall  have the  right to  change  a  Beneficiary  by  completing,  signing  and
otherwise  complying with the terms of the Beneficiary  Designation Form and the
Plan  Administrator's  rules and procedures,  as in effect from time to time. If
the Participant  names someone other than his or her spouse as a Beneficiary,  a
spousal  consent,  in the form  designated  by the Plan  Administrator,  must be
signed by that Participant's spouse and returned to the Plan Administrator. Upon
the acceptance by the Plan  Administrator of a new Beneficiary  Designation Form
filed by the Participant,  all Beneficiary  designations previously filed by the
Participant shall be cancelled. The Plan Administrator shall be entitled to rely
on the last  Beneficiary  Designation Form filed by the Participant and accepted
by the Plan Administrator prior to the Participant's death.

     9.3   ACKNOWLEDGMENT.   No  designation  or  change  in  designation  of  a
Beneficiary  shall be  effective  --------------  until  received,  accepted and
acknowledged in writing by the Plan Administrator or its designated agent.

9.4          NO BENEFICIARY  DESIGNATION.  If a Participant fails to designate a
             Beneficiary  as provided in Sections  9.1, 9.2 and 9.3 above or, if
             all  designated  Beneficiaries  predecease  the  Participant or die
             prior to complete distribution of the Participant's  benefits, then
             the  Participant's  spouse  and  children  shall be the  designated
             Beneficiary.

     9.5 DOUBT AS TO BENEFICIARY.  If the Plan Administrator has any doubt as to
the proper Beneficiary  -----------------------  to receive payments pursuant to
this Plan,  the Plan  Administrator  shall have the  right,  exercisable  in its
discretion,  to cause the Participant's Employer to withhold such payments until
this matter is resolved to the Plan Administrator's satisfaction.

9.6          DISCHARGE OF OBLIGATIONS. The payment of benefits under the Plan to
             a Beneficiary  shall fully and  completely  discharge all Employers
             and the Plan Administrator from all further  obligations under this
             Plan with respect to the Participant,  and that  Participant's Plan
             Agreement shall terminate upon such full payment of benefits.

                                      TRUST

10.1         ESTABLISHMENT  OF THE TRUST. The Company shall have established and
             shall maintain the Trust.  The Employers shall transfer over to the
             Trust such assets,  if any, as the  Employers  determine,  in their
             sole discretion.

10.2         INTERRELATIONSHIP  OF THE PLAN AND THE TRUST. The provisions of the
             Plan  and  the  Plan  Agreement   shall  govern  the  rights  of  a
             Participant  to receive  distributions  pursuant  to the Plan.  The
             provisions  of the Trust shall govern the rights of the  Employers,
             Participants  and the  creditors  of the  Employers  to the  assets
             transferred  to the Trust.  Each Employer shall at all times remain
             liable to carry out its obligations under the Plan. Each Employer's
             obligations  under  the Plan may be  satisfied  with  Trust  assets
             distributed  pursuant  to the  terms  of the  Trust,  and any  such
             distribution  shall reduce the  Employer's  obligations  under this
             Agreement.

                                  MISCELLANEOUS

11.1         UNSECURED  GENERAL CREDITOR.  Participants and their  Beneficiaries
             successors  and assigns  shall have no legal or  equitable  rights,
             interests or claims in any  property or assets of an Employer.  Any
             and all of an Employer's assets shall be, and remain,  the general,
             unpledged,  unrestricted  assets  of the  Employer.  An  Employer's
             obligation  under the Plan shall be merely that of an unfunded  and
             unsecured promise to pay money in the future.

11.2         EMPLOYER'S  LIABILITY.  An Employer's  liability for the payment of
             benefits shall be defined only by the Plan and the Plan  Agreement,
             as entered into between the Employer and a Participant. An Employer
             shall have no obligation to a Participant  under the Plan except as
             expressly provided in the Plan and his or her Plan Agreement.

11.3         NONASSIGNABILITY.  Neither a Participant nor any other person shall
             have  any  right  to  commute,  sell,  assign,  transfer,   pledge,
             anticipate,  mortgage or otherwise encumber, transfer,  hypothecate
             or convey  in  advance  of actual  receipt,  the  amounts,  if any,
             payable hereunder,  or any part thereof,  which are, and all rights
             to  which  are,   expressly   declared  to  be,   unassignable  and
             non-transferable.  No part of the amounts  payable shall,  prior to
             actual  payment,  be subject to  seizure or  sequestration  for the
             payment of any debts,  judgments,  alimony or separate  maintenance
             owed by a Participant or any other person,  nor be  transferable by
             operation  of law in the  event  of a  Participant's  or any  other
             person's bankruptcy or insolvency.

11.4         NOT A CONTRACT OF EMPLOYMENT. The terms and conditions of this Plan
             shall not be deemed to constitute a contract of employment  between
             any  Employer  and  the  Participant.  Such  employment  is  hereby
             acknowledged to be an "at will" employment relationship that can be
             terminated  at any  time for any  reason,  with or  without  cause,
             unless  otherwise   expressly  provided  in  a  written  employment
             agreement.  Nothing  in  this  Plan  shall  be  deemed  to  give  a
             Participant the right to be retained in the service of any Employer
             or to  interfere  with the right of any Employer to  discipline  or
             discharge the Participant at any time.

     11.5 FURNISHING  INFORMATION.  A Participant or his or her Beneficiary will
cooperate  with the Plan  Administrator  by furnishing  any and all  information
requested  by the Plan  Administrator  and take  such  other  actions  as may be
requested in order to facilitate the administration of the Plan and

             the payments of benefits  hereunder,  including  but not limited to
             taking such physical  examinations  as the Plan  Administrator  may
             deem necessary.

11.6         TERMS.  Whenever any words are used herein in the  masculine,  they
             shall be construed as though they were in the feminine in all cases
             where they would so apply;  and  wherever any words are used herein
             in the singular or in the plural, they shall be construed as though
             they were used in the plural or the  singular,  as the case may be,
             in all cases where they would so apply.

11.7         CAPTIONS. The captions of the articles,  sections and paragraphs of
             this Plan are for convenience  only and shall not control or affect
             the meaning or construction of any of its provisions.

     11.8 GOVERNING LAW.  Subject to ERISA, the provisions of this Plan shall be
construed and interpreted  according to the internal laws of the State of Nevada
without regard to its conflict of laws principles.

11.9         VALIDITY.  In case any  provision  of this Plan shall be illegal or
             invalid for any reason,  said  illegality or  invalidity  shall not
             affect the remaining parts hereof, but this Plan shall be construed
             and  enforced as if such  illegal and invalid  provision  had never
             been inserted herein.

11.10        NOTICE.  Any notice or filing  required or permitted to be given to
             the Plan  Administrator  under this Plan shall be  sufficient if in
             writing and  hand-delivered,  or sent by  registered  or  certified
             mail, to the address below:

                              Sierra Health Services, Inc.
                              2724 North Tenaya Way

                              Attn.: Office of General Counsel

             Such notice shall be deemed given as of the date of delivery or, if
             delivery is made by mail,  as of the date shown on the  postmark on
             the receipt for registration or certification.

             Any  notice  or  filing  required  or  permitted  to be  given to a
             Participant  under this Plan shall be  sufficient if in writing and
             hand-delivered,  or sent by mail,  to the last known address of the
             Participant.

11.11        SUCCESSORS. The provisions of this Plan shall bind and inure to the
             benefit  of the  Participant's  Employer  and  its  successors  and
             assigns and the Participant and the Participant's Beneficiary(ies).

11.12        SPOUSE'S  INTEREST.  The  interest in the  benefits  hereunder of a
             spouse of a Participant who has  predeceased the Participant  shall
             automatically pass to the Participant and shall not be transferable
             by such  spouse in any  manner,  including  but not limited to such
             spouse's  will,  nor shall  such  interest  pass  under the laws of
             intestate succession.

11.13        INCOMPETENT. If the Plan Administrator determines in its discretion
             that a benefit  under this Plan is to be paid to a minor,  a person
             declared  incompetent  or to a person  incapable  of  handling  the
             disposition of that person's  property,  the Plan Administrator may
             direct   payment   of  such   benefit   to  the   guardian,   legal
             representative or person having the care and custody of such minor,
             incompetent or incapable person. The Plan Administrator may require
             proof of minority, incompetency,  incapacity or guardianship, as it
             may deem appropriate prior to distribution of the


                                                         13

             benefit.  Any  payment  of a  benefit  shall be a  payment  for the
             account of the Participant and the  Participant's  Beneficiary,  as
             the case may be, and shall be a complete discharge of any liability
             under the Plan for such payment amount.

     11.14  COURT  ORDER.  The  Plan  Administrator  is  authorized  to make any
payments  directed  by court  order  in any  action  in  which  the Plan or Plan
Administrator has been named as a party.

11.15        DISTRIBUTION IN THE EVENT OF TAXATION.  If, for any reason,  all or
             any  portion of a  Participant's  benefit  under this Plan  becomes
             taxable to the  Participant  prior to receipt,  a  Participant  may
             petition the Plan  Administrator for a distribution of that portion
             of his or her benefit  that has become  taxable.  Upon the grant of
             such a petition,  which grant shall not be unreasonably withheld, a
             Participant's   Employer  shall   distribute  to  the   Participant
             immediately  available  funds in an  amount  equal  to the  taxable
             portion  of his or her  benefit  (which  amount  shall not exceed a
             Participant's  unpaid  Account  Balance  under  the  Plan).  If the
             petition is granted,  the tax liability  distribution shall be made
             within  90 days of the date  when  the  Participant's  petition  is
             granted.  Such a distribution  shall affect and reduce the benefits
             to be paid under this Plan.

         1. Employee shall not at any time or in any manner,  either directly or
indirectly, divulge, disclose or communicate to any person, firm or corporation,
in any manner whatsoever, any proprietary or confidential information concerning
any  matter   affecting   or  relating  to  the  business  of  Employer  or  its
subsidiaries, including without limiting the generality of the foregoing, any of
their customers, the prices they obtain from providers or have obtained from the
sale of,  or at  which  they  sell or have  sold,  its  services,  or any  other
information  concerning  the  business of Employer  or its  subsidiaries,  their
manner of operation,  or their plans, if such a disclosure  would be detrimental
to the business interests of the Employer or its subsidiaries.
         2.  If this  Agreement  is  terminated  by  either  party  at any  time
hereafter,  then the  Employee  agrees to turn over to the  Employer all papers,
documents, working papers, correspondence, memos and any and all other documents
in  Employee's  possession  relating to or  concerning  any matter  affecting or
relating to the business of the Employer or its subsidiaries.
                                   ARTICLE VI
                            NONCOMPETITION AGREEMENT
         1. The Employee  acknowledges that in Employee's  employment hereunder,
Employee will have continual  contacts with the groups,  members,  and providers
who are covered by or associated  with the managed health care programs  offered
by the  Employer  or its  subsidiaries  in Nevada  and other  states.  In all of
Employee's activities, the Employee, through the nature of Employee's work, will
have access to and will acquire confidential information related to the business
and operations of the Employer and its subsidiaries, including, without limiting
the  generality  of the  foregoing,  member and group  lists,  and  confidential
information relating to processes,  plans, methods of doing business and special
needs of doctors,  hospitals,  members, groups, pharmacies, or other health care
providers  who  contract  with the  Employer or its  subsidiaries.  The Employee
acknowledges  that all such  information  is the property of the Employer or its
subsidiaries  solely and constitutes  confidential  information of such parties;
that the disclosure  thereof would cause substantial loss to the goodwill of the
Employer and its subsidiaries;  that disclosure thereof to the Employee is being
made only because of the position of trust and  confidence  which  Employee will
occupy and because of Employee's agreement to the restrictions herein contained;
that his  knowledge of these matters  would enable him, on  termination  of this
Agreement,  to compete with the Employer or its  subsidiaries in a manner likely
to cause the Employer and its subsidiaries  irreparable  harm, and disclosure of
such matters would, likewise, cause such harm; and that the restrictions imposed
upon the Employee herein would not prohibit the Employee in earning a living.
         2. It is  understood  and agreed by the Employee and the Employer  that
the essence of this Employment  Agreement is the mutual covenants of the parties
herein made that the present  and future  members and groups of the  Employer or
its  subsidiaries  will remain the Employer's or its  subsidiaries'  members and
groups during the term of this Agreement and in the event of its termination for
any reason by either party.  In  consideration  for the employment and continued
employment of the Employee by the Employer,  and also for the amount received by
the  Employee  as  compensation,   the  Employee  hereby  irrevocably  warrants,
covenants, and agrees as follows:
                  (a) during the term of Employee's employment and after leaving
the employment of the Employer for any reason, whether involuntary or voluntary,
the Employee will not take any action  whatsoever which may or might disturb any
existing  business  relationship  of the Employer or its  subsidiaries  with any
doctors, groups, members,  hospitals,  pharmacies or other health care providers
in Nevada who contract with the Employer or its subsidiaries;
                  (b) for a period of one (1) year after leaving the  employment
of the Employer,  Employee will not solicit  business from the members or groups
of the  Employer or its  subsidiaries  in Nevada,  or in any manner  disrupt any
business  relationship  the Employer or its subsidiaries has with any contracted
health care provider in Nevada with whom Employee came in contact as an employee
of the Employer.
                  (c) for a period of one (1) year after leaving the  employment
of the Employer,  Employee will not, either directly or indirectly, work for any
present or future  competitors of Employer  operating in the state of Nevada who
in any manner offer any managed health care  programs,  insurance  coverage,  or
administer health care claims for employers. Such competitors shall include, but
are not limited to, HMOs,  PPOs,  insurance  companies,  utilization  management
companies, or third party administrators.
         3. The one (1) year period  specified  in this  Article  will be tolled
during any period of breach of any of the terms of Article VII by the Employee.
         4. The  Employee  agrees  that in the  event of a breach of any term of
this Agreement,  and more  particularly,  in the event of a breach of any of the
terms and provisions of Article VII, the Employer shall be entitled to secure an
order in any suit brought for that purpose to enjoin the Employee from violating
any of the  provisions of the  Agreement  and that,  pending the hearing and the
decision on the application for such order,  the Employer shall be entitled to a
temporary  restraining  order without prejudice to any other remedy available to
the Employer,  all at the expense of the Employee should the Employer prevail in
such action. The Employee understands that the covenants of this Article are the
essence of this Employment Agreement,  and without which no Employment Agreement
with the Employee would be entered into by the Employer.
         5. The  provisions  of Article VII shall in no event be construed to be
an exclusive remedy and such remedy shall be held and construed to be cumulative
and not exclusive of any rights or remedies, whether in law or equity, otherwise
available  under the  terms of this  Agreement  or under the laws of the  United
States or the state of Nevada.
         6. The  covenants and  agreements  made by the Employee in this Article
VII shall be construed as an agreement independent of any other provision in the
Agreement  and the  existence  of any claim or cause of  action by the  Employee
against the Employer,  whether predicated on this Agreement or otherwise,  shall
not  constitute a defense to the  enforcement  by the  Employer,  by  injunctive
relief or otherwise,  of the provisions of Article VII. The invalidity of all or
any part of any  section  or  paragraph  of this  Article  VII shall not  render
invalid the remainder of this Article or any section hereof.
         7. No failure or  failures  on the part of the  Employer to enforce any
violation by the Employee of this Noncompetition  agreement,  shall constitute a
waiver  of the  Employer's  rights  thereafter  to  enforce  all  of the  terms,
covenants, provisions and agreements herein contained.
                                   ARTICLE VII
                            TERMINATION OF EMPLOYMENT

appropriate notice, except as otherwise specifically set forth in this Article.
         2. The Employee may terminate this  Agreement and employment  hereunder
with  sixty  (60) days prior  written  notice.  If  Employee  shall  voluntarily
terminate the Agreement all eligible separation compensation and benefits as are
routinely  made  available  to  other  employees  of the  Employer  at the  same

         4.  Notwithstanding  any  other  provision  in  this  Agreement  to the

days, 37 1/2% after the first 180 days,  and the remaining 37 1/2% at the end of
365 days.  Payment of such amounts shall fully release the Employer from any and
all  liability of the  Employer  relating to this  Agreement  or the  employment
hereunder.
         5. If Employer shall terminate the Agreement for Employee  conduct that
is materially detrimental to the Company's reputation,  business  relationships,
or for misappropriation of Employer's funds, Employee shall be eligible for four
(4) weeks'  salary and any other  separation  compensation  and  benefits as are
routinely  made  available  to  other  employees  of the  Employer  at the  same
organizational level, as full and final payment under this Agreement. Payment of
such amounts  shall fully release the Employer from any and all liability of the
Employer relating to this Agreement or the employment  hereunder.  6. (a) If the
Employee is unable to perform Employee's duties hereunder,  by reason of illness
or incapacity of any kind,  for a period of more than THREE (3) MONTHS in excess
of accrued sick leave,  this  Agreement,  and the  employment  hereunder  may be
terminated  by the  Employer at its absolute  discretion  with one week of prior
written notice.  (b) If the Employee's  illness or incapacity  shall have ended,
and the Employee shall have assumed  Employee's duties  hereunder,  prior to the
date  specified  in the notice of  termination,  Employee  shall be  entitled to
resume Employee's employment hereunder as if such notice had not been given.
                  (c) In the event of the death of the Employee  during the term
of this Agreement, the Employer shall be required to pay the Employee's personal
representative or the executor or administrator of the Employee's estate,  THREE
(3) MONTHS of the Employee's  total prior year's annual  compensation  including
both salary and bonus. Such payment shall be in addition to any other payment to
which the Employee or their estate is otherwise  eligible for under the terms of
this Agreement.
         7. In the event of a change in control  of the  Employer,  whereby  any
"person"  (as  such  term  is used  in  Sections  3(a)(9)  and  13(d)(3)  of the
Securities Exchange Act of 1934) is or becomes the beneficial owner, directly or
indirectly,  of securities of Employer  representing 51% or more of the combined
voting power of the then outstanding  securities of Employer, and such change in
control was not  approved by a majority of the Board of  Directors  of Employer,
Employee,  at his/her sole option, shall be entitled to terminate this Agreement
and will be  entitled  to TWELVE (12)  MONTH'S  salary and any other  separation
compensation  and benefits as are routinely made available to other employees of
the Employer at the same  organizational  level.  Payment of such amounts  shall
fully release the Employer  from any and all liability of the Employer  relating
to this Agreement or the employment hereunder.
         8. In the event of a change in control  of the  Employer,  whereby  any
"person"  (as  such  term  is used  in  Sections  3(a)(9)  and  13(d)(3)  of the
Securities Exchange Act of 1934) is or becomes the beneficial owner, directly or
indirectly,  of securities of Employer  representing 51% or more of the combined
voting power of the then outstanding  securities of Employer, and such change in
control  is  approved  by a  majority  of the Board of  Directors  of  Employer,
Employee,  at his/her sole option, shall be entitled to terminate this Agreement
and  will be  entitled  to one  (l)  year's  salary  and  any  other  separation
compensation  and benefits as are routinely made available to other employees of
the Employer at the same organizational  level if, within one (l) year after the
effective  date of the  change in control  the  Employee's  principal  duties or
compensation, including salary and bonus, is materially changed. It is expressly
understood  that a change in who the Employee  reports to shall not constitute a
material change in duties. In addition,  if the Employee's  employment hereunder
is  terminated  for  reasons  other than those set forth in  Paragraph 4 of this
Article  within one year after the  effective  date of a change in control which
was approved by a majority of the Employer's Board of Directors,  Employee shall
be entitled to TWELVE (12) MONTH'S salary and all other separation  compensation
and benefits as are routinely made available to other  employees of the Employer
at the same  organizational  level.  Payment of such amounts shall fully release
the  Employer  from  any and all  liability  of the  Employer  relating  to this
Agreement or the employment hereunder.
         9. Anything  contained  herein to the contrary  notwithstanding  in the
event that  Employer  shall  discontinue  operation of Employer  other than as a
result of a merger,  consolidation  or  acquisition,  then this Agreement  shall
terminate  as of the last day of the month in which  Employer  ceases  operation
with the same force and effect as if such last day of the month were  originally
set as the termination date hereof.

                                EFFECT OF WAIVER
         The  waiver  by  either  party of a  breach  of any  provision  of this
agreement shall not operate or be construed as a waiver of any subsequent breach
thereof.

interest  adverse to  Employer;  provided,  however,  that  Employee may provide

      1.  Employee  shall not at any time or in any manner,  either  directly or
indirectly, divulge, disclose or communicate to any person, firm or corporation,
in any manner whatsoever, any proprietary or confidential information concerning
any  matter   affecting   or  relating  to  the  business  of  Employer  or  its
subsidiaries, including without limiting the generality of the foregoing, any of
their customers, the prices they obtain from providers or have obtained from the
sale of,  or at  which  they  sell or have  sold,  its  services,  or any  other
information  concerning  the  business of Employer  or its  subsidiaries,  their
manner of operation,  or their plans, if such a disclosure  would be detrimental
to the business interests of the Employer or its subsidiaries.
      2. If this Agreement is terminated by either party at any time  hereafter,
then the Employee  agrees to turn over to the  Employer  all papers,  documents,
working  papers,  correspondence,  memos  and  any and all  other  documents  in
Employee's possession relating to or concerning any matter affecting or relating
to the business of the Employer or its subsidiaries.

                                   ARTICLE VI
                            NONCOMPETITION AGREEMENT
      1. The Employee  acknowledges  that in  Employee's  employment  hereunder,
Employee will have continual  contacts with the groups,  members,  and providers
who are covered by or associated  with the managed health care programs  offered
by the  Employer  or its  subsidiaries  in Nevada  and other  states.  In all of
Employee's activities, the Employee, through the nature of Employee's work, will
have access to and will acquire confidential information related to the business
and operations of the Employer and its subsidiaries, including, without limiting
the  generality  of the  foregoing,  member and group  lists,  and  confidential
information relating to processes,  plans, methods of doing business and special
needs of doctors,  hospitals,  members, groups, pharmacies, or other health care
providers  who  contract  with the  Employer or its  subsidiaries.  The Employee
acknowledges  that all such  information  is the property of the Employer or its
subsidiaries  solely and constitutes  confidential  information of such parties;
that the disclosure  thereof would cause substantial loss to the goodwill of the
Employer and its subsidiaries;  that disclosure thereof to the Employee is being
made only because of the position of trust and  confidence  which  Employee will
occupy and because of Employee's agreement to the restrictions herein contained;
that her  knowledge of these matters  would enable her, on  termination  of this
Agreement,  to compete with the Employer or its  subsidiaries in a manner likely
to cause the Employer and its subsidiaries  irreparable  harm, and disclosure of
such matters would, likewise, cause such harm; and that the restrictions imposed
upon the Employee herein would not prohibit the Employee in earning a living.
      2. It is  understood  and agreed by the Employee and the Employer that the
essence of this  Employment  Agreement  is the mutual  covenants  of the parties
herein made that the present  and future  members and groups of the  Employer or
its  subsidiaries  will remain the Employer's or its  subsidiaries'  members and
groups during the term of this Agreement and in the event of its termination for
any reason by either party.  In  consideration  for the employment and continued
employment of the Employee by the Employer,  and also for the amount received by
the  Employee  as  compensation,   the  Employee  hereby  irrevocably  warrants,
covenants, and agrees as follows:
               (a) during the term of  Employee's  employment  and after leaving
the employment of the Employer for any reason, whether involuntary or voluntary,
the Employee will not take any action  whatsoever which may or might disturb any
existing  business  relationship  of the Employer or its  subsidiaries  with any
doctors, groups, members,  hospitals,  pharmacies or other health care providers
in Nevada who contract with the Employer or its subsidiaries;
               (b) for a period of one (1) year after leaving the  employment of
the Employer,  Employee will not solicit  business from the members or groups of
the  Employer  or its  subsidiaries  in  Nevada,  or in any manner  disrupt  any
business  relationship  the Employer or its subsidiaries has with any contracted
health care provider in Nevada with whom Employee came in contact as an employee
of the Employer.
               (c) for a period of one (1) year after leaving the  employment of
the Employer,  Employee will not,  either  directly or indirectly,  work for any
present or future  competitors of Employer  operating in the state of Nevada who
in any manner offer any managed health care  programs,  insurance  coverage,  or
administer health care claims for employers. Such competitors shall include, but
are not limited to, HMOs,  PPOs,  insurance  companies,  utilization  management
companies, or third party administrators.
      3. The one (1) year period specified in this Article will be tolled during
any period of breach of any of the terms of Article VII by the Employee.
      4. The  Employee  agrees that in the event of a breach of any term of this
Agreement,  and more particularly,  in the event of a breach of any of the terms
and provisions of Article VII, the Employer shall be entitled to secure an order
in any suit brought for that purpose to enjoin the Employee  from  violating any
of the  provisions  of the  Agreement  and that,  pending  the  hearing  and the
decision on the application for such order,  the Employer shall be entitled to a
temporary  restraining  order without prejudice to any other remedy available to
the Employer,  all at the expense of the Employee should the Employer prevail in
such action. The Employee understands that the covenants of this Article are the
essence of this Employment Agreement,  and without which no Employment Agreement
with the Employee would be entered into by the Employer.
      5. The  provisions  of Article VII shall in no event be construed to be an
exclusive  remedy and such remedy shall be held and  construed to be  cumulative
and not exclusive of any rights or remedies, whether in law or equity, otherwise
available  under the  terms of this  Agreement  or under the laws of the  United
States or the state of Nevada.
      6. The  covenants and  agreements  made by the Employee in this Article VI
shall be  construed as an agreement  independent  of any other  provision in the
Agreement  and the  existence  of any claim or cause of  action by the  Employee
against the Employer,  whether predicated on this Agreement or otherwise,  shall
not  constitute a defense to the  enforcement  by the  Employer,  by  injunctive
relief or otherwise,  of the provisions of Article VII. The invalidity of all or
any part of any section or paragraph of this Article VI shall not render invalid
the remainder of this Article or any section hereof.
      7. No failure  or  failures  on the part of the  Employer  to enforce  any
violation by the Employee of this Noncompetition  agreement,  shall constitute a
waiver  of the  Employer's  rights  thereafter  to  enforce  all  of the  terms,
covenants, provisions and agreements herein contained.
                                   ARTICLE VII
                            TERMINATION OF EMPLOYMENT

1/2% after the first 180 days, and the remaining 37 1/2% at the end of 365 days.
Payment of such  amounts  shall  fully  release  the  Employer  from any and all
liability  of  the  Employer  relating  to  this  Agreement  or  the  employment
hereunder.

materially detrimental to the Company's reputation,  business relationships,  or
for  misappropriation  of Employer's funds,  Employee shall be eligible for FOUR
(4) WEEKS  salary and any other  separation  compensation  and  benefits  as are
routinely  made  available  to  other  employees  of the  Employer  at the  same
organizational level, as full and final payment under this Agreement. Payment of

(12) MONTHS in excess of accrued sick leave, this Agreement,  and the employment
hereunder may be terminated by the Employer at its absolute  discretion with one
week of prior written notice.
               (b) If the Employee's illness or incapacity shall have ended, and
the Employee shall have assumed  Employee's duties hereunder,  prior to the date
specified  in the notice of  termination,  Employee  shall be entitled to resume
Employee's employment hereunder as if such notice had not been given.
               (c) In the event of the death of the Employee  during the term of
this  Agreement,  the Employer shall be required to pay the Employee's  personal
representative  or the  executor  or  administrator  of the  Employee's  estate,

including both salary and bonus.  Such payment shall be in addition to any other
payment to which the Employee or their  estate is  otherwise  eligible for under
the terms of this Agreement.
      7. In the  event of a change  in  control  of the  Employer,  whereby  any
"person"  (as  such  term  is used  in  Sections  3(a)(9)  and  13(d)(3)  of the
Securities Exchange Act of 1934) is or becomes the beneficial owner, directly or

Securities Exchange Act of 1934) is or becomes the beneficial owner, directly or

                                EFFECT OF WAIVER

                                   ARTICLE IV

      Employee shall devote all of his time,  attention,  knowledge,  and skills
solely to the business and interest of Employer,  unless otherwise authorized by
the Employer, and Employer shall be entitled to all of the income,  benefits, or
profits arising from or incident to all work, work  associations,  services,  or
advice of Employee,  unless  otherwise  authorized  in writing by the  Employer.
Employee  shall not,  during the term hereof,  be interested  in any manner,  as
partner,  officer,  director,  advisor, employee or in any other capacity in any
other business similar to Employer's business or any allied trade, or obtain any
interest  adverse to  Employer;  provided,  however,  that  Employee may provide
advice and consultation to other entities with the written approval of Employer,
and further provided,  however, that nothing herein contained shall be deemed to
prevent or limit the right of Employee to invest any of his/her surplus funds in
the  capital  stock  or  other  securities  of any  corporation  whose  stock or
securities  are publicly owned or are regularly  traded on any public  exchange,
nor shall anything herein contained be deemed to prevent Employee from investing
or limit  Employee's  right to  invest  his/her  surplus  funds in real  estate.
Employee  shall  complete a Conflict  of  Interest  form by  February 15 of each
calendar  year and  submit it to the  Employer  for  review.  All  conflicts  of
interest or any potential conflicts of interest which arise during the year must
be immediately reported to the Employer.  All conflict of interest concerns must
be resolved to the  reasonable  satisfaction  of the  Employer as a condition of
continuation of employment.

                                    ARTICLE V
                                BUSINESS SECRETS
      1.  Employee  shall not at any time or in any manner,  either  directly or
indirectly, divulge, disclose or communicate to any person, firm or corporation,
in any manner whatsoever, any proprietary or confidential information concerning
any  matter   affecting   or  relating  to  the  business  of  Employer  or  its
subsidiaries, including without limiting the generality of the foregoing, any of
their customers, the prices they obtain from providers or have obtained from the
sale of,  or at  which  they  sell or have  sold,  its  services,  or any  other
information  concerning  the  business of Employer  or its  subsidiaries,  their
manner of operation,  or their plans, if such a disclosure  would be detrimental
to the business interests of the Employer or its subsidiaries.
      2. If this Agreement is terminated by either party at any time  hereafter,
then the Employee  agrees to turn over to the  Employer  all papers,  documents,
working  papers,  correspondence,  memos  and  any and all  other  documents  in
Employee's possession relating to or concerning any matter affecting or relating
to the business of the Employer or its subsidiaries.

                                   ARTICLE VI
                            NONCOMPETITION AGREEMENT
      1. The Employee  acknowledges  that in  Employee's  employment  hereunder,
Employee will have continual  contacts with the groups,  members,  and providers
who are covered by or associated  with the managed health care programs  offered
by the  Employer  or its  subsidiaries  in Nevada  and other  states.  In all of
Employee's activities, the Employee, through the nature of Employee's work, will
have access to and will acquire confidential information related to the business
and operations of the Employer and its subsidiaries, including, without limiting
the  generality  of the  foregoing,  member and group  lists,  and  confidential
information relating to processes,  plans, methods of doing business and special
needs of doctors,  hospitals,  members, groups, pharmacies, or other health care
providers  who  contract  with the  Employer or its  subsidiaries.  The Employee
acknowledges  that all such  information  is the property of the Employer or its
subsidiaries  solely and constitutes  confidential  information of such parties;
that the disclosure  thereof would cause substantial loss to the goodwill of the
Employer and its subsidiaries;  that disclosure thereof to the Employee is being
made only because of the position of trust and  confidence  which  Employee will
occupy and because of Employee's agreement to the restrictions herein contained;
that his  knowledge of these matters  would enable him, on  termination  of this
Agreement,  to compete with the Employer or its  subsidiaries in a manner likely
to cause the Employer and its subsidiaries  irreparable  harm, and disclosure of
such matters would, likewise, cause such harm; and that the restrictions imposed
upon the Employee herein would not prohibit the Employee in earning a living.
      2. It is  understood  and agreed by the Employee and the Employer that the
essence of this  Employment  Agreement  is the mutual  covenants  of the parties
herein made that the present  and future  members and groups of the  Employer or
its  subsidiaries  will remain the Employer's or its  subsidiaries'  members and
groups during the term of this Agreement and in the event of its termination for
any reason by either party.  In  consideration  for the employment and continued
employment of the Employee by the Employer,  and also for the amount received by
the  Employee  as  compensation,   the  Employee  hereby  irrevocably  warrants,
covenants, and agrees as follows:
               (a) during the term of  Employee's  employment  and after leaving
the employment of the Employer for any reason, whether involuntary or voluntary,
the Employee will not take any action  whatsoever which may or might disturb any
existing  business  relationship  of the Employer or its  subsidiaries  with any
doctors, groups, members,  hospitals,  pharmacies or other health care providers
in Nevada who contract with the Employer or its subsidiaries;
               (b) for a period of one (1) year after leaving the  employment of
the Employer,  Employee will not solicit  business from the members or groups of
the  Employer  or its  subsidiaries  in  Nevada,  or in any manner  disrupt  any
business  relationship  the Employer or its subsidiaries has with any contracted
health care provider in Nevada with whom Employee came in contact as an employee
of the Employer.
               (c) for a period of one (1) year after leaving the  employment of
the Employer,  Employee will not,  either  directly or indirectly,  work for any
present or future  competitors of Employer  operating in the state of Nevada who
in any manner offer any managed health care  programs,  insurance  coverage,  or
administer health care claims for employers. Such competitors shall include, but
are not limited to, HMOs,  PPOs,  insurance  companies,  utilization  management
companies, or third party administrators.
      3. The one (1) year period specified in this Article will be tolled during
any period of breach of any of the terms of Article VII by the Employee.
      4. The  Employee  agrees that in the event of a breach of any term of this
Agreement,  and more particularly,  in the event of a breach of any of the terms
and provisions of Article VII, the Employer shall be entitled to secure an order
in any suit brought for that purpose to enjoin the Employee  from  violating any
of the  provisions  of the  Agreement  and that,  pending  the  hearing  and the
decision on the application for such order,  the Employer shall be entitled to a
temporary  restraining  order without prejudice to any other remedy available to
the Employer,  all at the expense of the Employee should the Employer prevail in
such action. The Employee understands that the covenants of this Article are the
essence of this Employment Agreement,  and without which no Employment Agreement
with the Employee would be entered into by the Employer.
      5. The  provisions  of Article VII shall in no event be construed to be an
exclusive  remedy and such remedy shall be held and  construed to be  cumulative
and not exclusive of any rights or remedies, whether in law or equity, otherwise
available  under the  terms of this  Agreement  or under the laws of the  United
States or the state of Nevada.
      6. The  covenants and  agreements  made by the Employee in this Article VI
shall be  construed as an agreement  independent  of any other  provision in the
Agreement  and the  existence  of any claim or cause of  action by the  Employee
against the Employer,  whether predicated on this Agreement or otherwise,  shall
not  constitute a defense to the  enforcement  by the  Employer,  by  injunctive
relief or otherwise,  of the provisions of Article VII. The invalidity of all or
any part of any section or paragraph of this Article VI shall not render invalid
the remainder of this Article or any section hereof.
      7. No failure  or  failures  on the part of the  Employer  to enforce  any
violation by the Employee of this Noncompetition  agreement,  shall constitute a
waiver  of the  Employer's  rights  thereafter  to  enforce  all  of the  terms,
covenants, provisions and agreements herein contained.

                                   ARTICLE VII
                            TERMINATION OF EMPLOYMENT
      1.  Termination of employment by either  Employer or Employee shall follow
established Sierra Health Services Policies and Procedures including appropriate
notice, except as otherwise specifically set forth in this Article.
      2. The Employee may terminate this Agreement and employment hereunder with
sixty (60) days prior written notice.  If Employee shall  voluntarily  terminate
the Agreement all eligible separation compensation and benefits as are routinely
made  available to other  employees  of the Employer at the same  organizational
level, shall be paid or made available to the Employee.
      3. If Employer shall  terminate this  Agreement  without cause,  except as
otherwise set forth in Paragraph 7 of this Article,  Employee  shall be entitled
to  TWENTY-FOUR  (24) MONTHS salary and all other  separation  compensation  and
benefits as are routinely made  available to other  employees of the Employer at
the same organizational level.
      4.  Notwithstanding any other provision in this Agreement to the contrary,
Employee  hereby agrees that any  separation  compensation  due to the Employee,
other than accrued  vacation,  shall be paid out 25% after the first 90 days, 37
1/2% after the first 180 days, and the remaining 37 1/2% at the end of 365 days.
Payment of such  amounts  shall  fully  release  the  Employer  from any and all
liability  of  the  Employer  relating  to  this  Agreement  or  the  employment
hereunder.
      5. If Employer shall terminate the Agreement for Employee  conduct that is
materially detrimental to the Company's reputation,  business relationships,  or
for  misappropriation  of Employer's funds,  Employee shall be eligible for FOUR
(4) WEEKS  salary and any other  separation  compensation  and  benefits  as are
routinely  made  available  to  other  employees  of the  Employer  at the  same
organizational level, as full and final payment under this Agreement. Payment of
such amounts  shall fully release the Employer from any and all liability of the
Employer relating to this Agreement or the employment hereunder.
      6. (a) If the Employee is unable to perform  Employee's  duties hereunder,
by reason of illness or incapacity of any kind, for a period of more than TWELVE
(12) MONTHS in excess of accrued sick leave, this Agreement,  and the employment
hereunder may be terminated by the Employer at its absolute  discretion with one
week of prior written notice.
               (b) If the Employee's illness or incapacity shall have ended, and
the Employee shall have assumed  Employee's duties hereunder,  prior to the date
specified  in the notice of  termination,  Employee  shall be entitled to resume
Employee's employment hereunder as if such notice had not been given.
               (c) In the event of the death of the Employee  during the term of
this  Agreement,  the Employer shall be required to pay the Employee's  personal
representative  or the  executor  or  administrator  of the  Employee's  estate,
TWENTY-FOUR (24) MONTHS of the Employee's total prior year's annual compensation
including both salary and bonus.  Such payment shall be in addition to any other
payment to which the Employee or their  estate is  otherwise  eligible for under
the terms of this Agreement.
      7. In the  event of a change  in  control  of the  Employer,  whereby  any
"person"  (as  such  term  is used  in  Sections  3(a)(9)  and  13(d)(3)  of the
Securities Exchange Act of 1934) is or becomes the beneficial owner, directly or
indirectly,  of securities of Employer  representing 51% or more of the combined
voting power of the then outstanding  securities of Employer, and such change in
control was not  approved by a majority of the Board of  Directors  of Employer,
Employee,  at his/her sole option, shall be entitled to terminate this Agreement
and will be entitled to TWENTY-FOUR  (24) MONTHS salary,  which shall be grossed
up for taxes in an amount not to exceed fifty percent  (50%) of the  twenty-four
(24) months salary,  and any other  separation  compensation and benefits as are
routinely  made  available  to  other  employees  of the  Employer  at the  same
organizational  level.  Payment of such amounts shall fully release the Employer
from any and all  liability  of the Employer  relating to this  Agreement or the
employment hereunder.
      8. In the  event of a change  in  control  of the  Employer,  whereby  any
"person"  (as  such  term  is used  in  Sections  3(a)(9)  and  13(d)(3)  of the
Securities Exchange Act of 1934) is or becomes the beneficial owner, directly or
indirectly,  of securities of Employer  representing 51% or more of the combined
voting power of the then outstanding  securities of Employer, and such change in
control  is  approved  by a  majority  of the Board of  Directors  of  Employer,
Employee,  at his/her sole option, shall be entitled to terminate this Agreement
and will be entitled to TWENTY-FOUR  (24) MONTHS salary,  which shall be grossed
up for taxes in an amount not to exceed fifty percent  (50%) of the  twenty-four
(24) months salary,  and any other  separation  compensation and benefits as are
routinely  made  available  to  other  employees  of the  Employer  at the  same
organizational  level if,  within one (l) year after the  effective  date of the
change in control the Employee's  principal  duties or  compensation,  including
salary and bonus,  is  materially  changed.  It is expressly  understood  that a
change in who the Employee  reports to shall not constitute a material change in
duties. In addition,  if the Employee's  employment  hereunder is terminated for
reasons  other than those set forth in  Paragraph 4 of this  Article  within one
year after the  effective  date of a change in control  which was  approved by a
majority of the  Employer's  Board of Directors,  Employee  shall be entitled to
TWENTY-FOUR (24) MONTHS salary, which shall be grossed up for taxes in an amount

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

                                  ARTICLE VIII
                                EFFECT OF WAIVER
      The waiver by either party of a breach of any provision of this  agreement
shall not operate or be construed as a waiver of any subsequent breach thereof.

      This Agreement contains the entire Agreement between the parties,  and the
parties hereby agree that no other oral  representations or agreements have been
entered into in connection with this transaction.

      This Agreement, having been executed and delivered in the State of Nevada,
its validity,  interpretation,  performance and enforcement  will be governed by
