             NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - FINANCIAL STATEMENTS

In management's  opinion,  the  accompanying  unaudited  consolidated  financial
statements  contain  all  adjustments   (consisting  of  only  normal  recurring
adjustments)  considered  necessary for a fair  statement of the results for the
interim  periods  presented.  The  results of  operations  for the period  ended
February 29, 2000 are not  necessarily  indicative of the results to be expected
for the full year. The interim consolidated  financial statements should be read
in  conjunction  with  the  Lifemark   Corporation   ("Lifemark"  or  "Company")
consolidated  financial  statements and notes thereto  included in the Company's
Form 10-K for the year ended May 31, 1999.

NOTE 2 - NET INCOME PER SHARE

Basic net income per share is computed by  dividing  net income by the  weighted
average number of common shares  outstanding  during each period. Net income per
share  assuming  dilution is computed  by  dividing  net income by the  weighted
average  number of common  shares  outstanding  during the period  after  giving
effect to dilutive  stock options and warrants and adjusted for dilutive  common
shares assumed to be issued on conversion of the Company's convertible loans.

The following is the  computation  of the  reconciliation  of the numerators and
denominators  of net income  per common  share - basic and net income per common
share - assuming  dilution in accordance with Statement of Financial  Accounting
Standards No. 128, "Earnings Per Share".

of  their  revenues  through   contracts  with  the  Arizona  Health  Care  Cost
Containment System Administration ("AHCCCSA") to provide specified long-term and
acute care health services,  respectively,  to qualified  members.  The contract
periods  expire  September  30, 2001 and September 30, 2002 for Ventana and AHC,
respectively.  Each  contract  provides  for fixed  monthly  premiums,  based on
negotiated per capita enrollee rates.  Ventana and AHC subcontract  with nursing
homes, hospitals, physicians, and other medical providers within Arizona to care
for members.

Effective December 1, 1999, Lifemark of Texas, Inc. ("LMTX"), another subsidiary
of the Company,  contracted with Rio Grande HMO, Inc. ("RGHMO"), a subsidiary of
Health Care  Service  Corporation  ("HCSC")  formerly  Blue Cross Blue Shield of
Texas  ("BCBSTX"),  to share  financial  risk in the State of  Texas'  STAR+PLUS
program  contract in Harris County,  Texas.  The contract  expires on August 31,
2001, with the option to extend the contract for two additional one-year periods
upon mutual  agreement.  The  STAR+PLUS  program is the State of Texas'  managed
long-term care demonstration  project designed to provide  comprehensive managed
health  care  services  to aged,  blind  and  disabled  Medicaid  beneficiaries,
including  those  needing  long-term  care  services.  Lifemark has administered
RGHMO's   STAR+PLUS   program   ("HMO")   operations  since   its  inception  in
January  1998.  The  current  annualized  RGHMO  revenue  from  this  program is
approximately $100 million, and enrollment is approximately 20,000 members.

The  Company  also  provides  contract  management  services to county and state
governmental units and other health care organizations.  The Company's contracts
typically have multi-year terms, with its existing contracts expiring at various
dates through the year 2002.

RESULTS OF OPERATIONS

Consolidated  revenues for the three and  nine-month  periods ended February 29,
2000 increased 130% and 59%,  respectively,  over the comparable  periods of the
previous  fiscal year. For the three and  nine-month  periods ended February 29,
2000, direct costs of operations increased 182% and 73%, respectively,  over the
same periods of the  previous  fiscal  year.  The increase in both  revenues and
expenses is  primarily a result of the  financial  risk sharing  agreement  with
RGHMO and growth in enrollment in the RGHMO and Community Choice Michigan plans,
along with an increase in membership for both Ventana and AHC.

MANAGEMENT  SERVICES.  For the  three-month  period  ended  February  29,  2000,
revenues generated from fees for management services decreased 13% to $8,492,000
from $9,782,000 for the equivalent period of the prior fiscal year. The decrease
primarily represents the change in a contractual  relationship with RGHMO from a
management  services  agreement  to a financial  risk  sharing  agreement  which
resulted in a reclassification  of $2,684,000 as long-term care service revenues
effective  December  1, 1999.  Excluding  the  impact of this  reclassification,
revenues from management  services  increased  $1,394,000,  which represents 14%
growth during the current quarter as compared with the same quarter of the prior
fiscal  year.  For the  nine-month  period ended  February  29,  2000,  revenues
generated from fees for management  services  increased 11% to $31,096,000  from
$27,895,000 for the corresponding  period of the prior fiscal year. The increase
during both the three and nine-month periods ended February 29, 2000,  excluding
the impact of the  reclassification,  is attributable to the growth in Community
Choice Michigan enrollment,  the acquisition of Advinet, Inc. in March 1999, and
the renegotiated administrative services agreement with AlohaCare.

Direct costs of operations for the three and  nine-month  periods ended February
29, 2000  included  $3,851,000  and  $15,593,000  respectively,  related to fees
generated from management services of health plans and programs. The direct cost
of operations  for management  services as a percentage of related  revenues for
the three and  nine-month  periods ended  February 29, 2000 decreased 7% and 3%,
respectively, from the comparable periods of the previous fiscal year to 45% and
50%, due in part to  initiatives  to strengthen  Lifemark's  infrastructure  and
technology and increased profitability from the Company's renegotiated agreement
with AlohaCare, which was effective August 1, 1999 and expires July 31, 2000.

LONG-TERM CARE HEALTH  SERVICES.  Long-term  care health and personal  services,
which consists of the operations of Ventana,  Lifemark at Home,  Inc., and LMTX,
generated  revenues of $35,759,000  and $51,678,000 for the three and nine-month
periods ended  February 29, 2000,  respectively,  as compared to $7,410,000  and
$21,192,000  for  the  corresponding  periods  of the  prior  fiscal  year.  The
increases  during the three month period ended  February 29, 2000 are  primarily
due to LMTX revenues of  $23,549,000  described  above under the  `Introduction'
caption,  growth in Ventana  membership  with the  addition of two new  counties
which generated revenues of $3,868,000, and the purchase of Valleywide Attendant
Care in January 2000, which contributed revenues of $108,000.

Ventana was awarded  contracts  covering two additional rural Arizona  counties,
effective  December  1, 1999.  These  additional  counties  added 550 members to
Ventana's  membership and accounted for $3,868,000 in additional revenues during
the quarter ended February 29, 2000.

In January 2000, the Company  acquired  Valleywide  Attendant Care, who performs
non-medical  home and community based services in Maricopa and Pinal counties in
Arizona.   The  Company  paid  $143,000  for   Valleywide   Attendant  Care  and
incorporated its operations into its existing Lifemark at Home, Inc. subsidiary.

Direct costs of  operations  related to long-term  care health  services for the
three and  nine-month  periods  ended  February  29, 2000 were  $34,359,000  and
$48,373,000,  respectively,  versus  $6,451,000  and  $18,337,000  for the  same
periods of last fiscal year. As a percentage of related revenues, direct cost of
operations  related to long-term care health  services  increased to 96% and 94%
for the three and  nine-month  periods  ended  February 29, 2000,  respectively,
versus 87% for both  periods of the  previous  fiscal year.  The  increases  are
primarily due to the addition of LMTX, which  experienced  higher direct cost of
operations  as a  percentage  of  related  revenues  than other  long-term  care
services segment operations.

ACUTE CARE HEALTH SERVICES.  Acute care health  services,  which consists of the
operations of AHC,  generated  revenues of $5,399,000  and  $15,058,000  for the
three and nine-month periods ended February 29, 2000, respectively, representing
a 23% and 22%  increase  over the  comparable  periods of the prior fiscal year,
respectively. The change was caused by the recognition of the final prior period
coverage  settlement  for  September 30, 1999,  an  increase  in  membership  of
AHC and  approximately  6%  increase in the capitation rate received by AHC from
AHCCCSA.

Direct costs of operations  related to acute care health  services for the three
and nine-month  periods ended February 29, 2000 were $5,208,000 and $15,258,000,
respectively,  versus  $4,470,000  and  $12,479,000  for the same periods of the
previous  fiscal year.  Direct costs of  operations  as a percentage  of related
revenues  decreased to 96% for the three month  period  ended  February 29, 2000
versus 102% for the comparable  period of the prior fiscal year,  while the nine
month  period  ended  February  29, 2000  remained at 101% when  compared to the
comparable  period  from the prior  fiscal  year.  The change  relates to higher
revenues  generated by AHC due to a reconciliation  of capitation  reimbursement
from AHCCCSA.

MARKETING,  SALES  AND  ADMINISTRATIVE.   Marketing,  sales  and  administrative
expenses  decreased  $37,000 to  $5,108,000  for the  three-month  period  ended
February 29,  2000,  when  compared to the same period for the  previous  fiscal
year.  Marketing,   sales  and  administrative   expenses  as  a  percentage  of
consolidated  revenue  were  10%  and  17%,  respectively,  for  the  three  and
nine-month periods ended February 29, 2000 versus 24% and 23%, respectively, for
the corresponding periods of the previous year. The decrease in marketing, sales
and  administrative  expenses  for the three  months  ended  February  29,  2000
compared with the same quarter of the prior fiscal year is primarily a result of
LMTX entering into the financial  risk sharing  agreement  with RGHMO  effective
December  1, 1999.  LMTX,  similar to other  health plan  operations,  typically
experiences significantly less marketing, sales and administrative expenses as a
percentage  of related  revenue when compared  with an  administrative  services
contract structure. An increase in profitability due to membership growth in the
RGHMO and Community  Choice Michigan plans has also contributed to the reduction
in  marketing,  sales and  administrative  expenses as a  percentage  of related
revenue during the current fiscal year. In addition, prior year marketing, sales
and  administrative  expenses  included  consulting  fees related to  management
reorganization  and process redesign  intended to improve the Company's  service
delivery system.  The Company did not incur significant  consulting fees related
to this initiative in the current fiscal year.

INTEREST  INCOME.  Interest  income for the three and  nine-month  periods ended
February 29, 2000 was $614,000 and $1,137,000  versus  $234,000 and $720,000 for
the same periods of the prior  fiscal year.  The  additional  income  during the
current fiscal year is primarily  attributable  to LMTX's share of income earned
on investments  attributable to RGHMO's STAR+PLUS operations of $256,000 as well
as the growth of the Company's interest bearing cash and cash equivalents.

INTEREST  EXPENSE.  Interest  expense was $99,000 and $292,000 for the three and
the  nine-month  periods ended February 29, 2000,  respectively,  as compared to
$91,000 and $271,000  for the same  periods of the last fiscal year.  During the
current  quarter,  Lifemark  repaid  its  $3,000,000  convertible  loan to HCSC,
replacing  it with a  four-year  term note with a bank.  The warrant to purchase
100,000  shares of the  Company's  common stock held by HCSC as part of the loan
transaction  was also  terminated.  The loans  mentioned  above  coupled with an
interim  funding  agreement  obtained  from a bank during the fourth  quarter of
fiscal year 1999 were the  primary  reasons for the  interest  expense  incurred
during both the three and  nine-months  periods  ended  February 29,  2000.  The
Company   has   borrowed   $841,000   under   this   funding   agreement  as  of
February 29, 2000.

INCOME TAXES. Income tax expense was $830,000 and $1,391,000 for the three-month
and nine-month periods ended February 29, 2000, respectively.  The effective tax
rates were 51% and 47%, respectively. These rates were higher than the statutory
rates  for  the  respective   periods  primarily  due  to  the  amortization  of
non-deductible  goodwill expense.  During the three-month and nine-month periods
ended  February 28, 1999,  the  effective  tax rate was 22%.  These rates were a
result of the  reduction  in the deferred  tax  valuation  allowance of $366,000
based on the Company's  assessment of the  realizeability of deferred tax assets
partially offset by amortization of non-deductible goodwill expense.

NET INCOME.  Net income for the three and nine-month  periods ended February 29,
2000 was $809,000 and  $1,538,000 as compared to $618,000 and $1,532,000 for the
comparable  periods of the previous  fiscal year. The increase in  profitability
for the three and nine-month periods ended February 29, 2000 is primarily due to
the enhanced profitability in the management services segment with the growth in
enrollment in the Community  Choice Michigan and RGHMO plans.  The  renegotiated
administrative  service  agreement  with AlohaCare effective August 1, 1999 also
contributed to the increase  in  net income.  Additional  income  generated from
the  management  services  segment was partially  offset by  increases in direct
expenses as a percentage of related revenue in the long-term care and acute care
health service segments.

LIQUIDITY AND CAPITAL RESOURCES

The Company's cash and cash equivalents increased to $15,924,000 at February 29,
2000 from $13,792,000 at May 31, 1999. Operating activities generated $8,635,000
for the nine-month  period ended February 29, 2000 versus  $3,444,000 during the
same period of the previous fiscal year. The primary reasons for the increase in
cash are earnings  before  non-cash  charges,  a refundable  deposit of $650,000
obtained from AlohaCare pursuant to the terms of the renegotiated administrative
services agreement,  receipt of a $600,000 incentive fee payment pursuant to the
administrative  services  agreement  with RGHMO,  an increase in accrued  income
taxes and an increase in accrued medical expenses. The growth in accrued medical
expenses  was related to LMTX  operations,  and for both  Ventana  and AHC,  the
annual  increases  in  fee-for-service  rates  paid to  providers  coupled  with
enrollment  growth.  The growth in cash was  partially  offset by an increase in
accounts receivable caused by the  financial risk  sharing  agreement with RGHMO
and  a  payment  of  $844,000  in  interest  to  HCSC relating to the $3,000,000
convertible debt.

Investing  activities used  $7,105,000 for the nine-month  period ended February
29, 2000 as compared to $232,000  during the  corresponding  period of the prior
fiscal year.  Cash of  $2,966,000  was used to purchase  fixed assets during the
nine-month period ended February 29, 2000. Other uses of cash for the nine-month
period ended February 29, 2000 included the purchase of a certificate of deposit
for  $2,878,000.  The  Company  pledged the  certificate  of deposit to RGHMO to
secure its  obligations  under the financial  risk sharing  agreement with RGHMO
effective  December 1999. In addition,  Ventana and AHC invested  $2,398,000 and
$222,000 in assets securing performance bonds during the nine-month period ended
February 29, 2000, due to increased enrollment.  During the same period, sources
of cash included the sale of fixed assets to AlohaCare for $285,000 pursuant  to
the terms of the  renegotiated  administrative  services  agreement and maturity
of Ventana's short-term investments of $501,000.  During  the  nine-month period
ended February  28, 1999, cash was used to purchase  $1,003,000  of fixed assets
and $1,645,000 was used to purchase additional short-term investments.

                                       13
<PAGE>

Financing  activities generated $602,000 and $43,000 for the nine-month  periods
ended February 29, 2000 and 1999, respectively.  Issuance  of common stock under
the employee stock purchase plan  provided  $198,000  for the nine-month  period
ended  February 29, 2000  while  principal  payments  on long-term debt utilized
$155,000.  During  the  current  quarter,  the  Company  repaid  its  $3,000,000
convertible loan to HCSC,  replacing it with a four-year  term note with a bank.
The warrant held by HCSC to  purchase  100,000  shares  of the  Company's common
stock was also terminated as part of the transaction.

Certain of the Company's operating subsidiaries are subject to state regulations
which require compliance with net worth,  reserve and deposit  requirements.  To
the extent the operating  subsidiaries must comply with these regulations,  they
may not have the financial flexibility to transfer funds to Lifemark. Net assets
of subsidiaries (after inter-company  eliminations) which, at February 29, 2000,
may not be  transferred  to  Lifemark  by  subsidiaries  in the  form of  loans,
advances or cash dividends  without the consent of a third party are referred to
as  "Restricted  Net Assets".  Total  Restricted  Net Assets of these  operating
subsidiaries  was  $12,429,000  at February 29,  2000,  with deposit and reserve
requirements  (performance bonds) representing  $6,923,000 of the Restricted Net
Assets  and  net  worth   requirements,   in  excess  of  deposit   and  reserve
requirements,  representing  the  remaining  $5,506,000.  There  were  no  funds
provided by Ventana to Lifemark under loan agreements at February 29, 2000.

The Company believes that its existing capital resources and cash flow generated
from  future  operations  will  enable  it to  maintain  its  current  level  of
operations and its planned operations, including capital expenditures, in fiscal
year 2000.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The Company is a party to an administrative  services  agreement with Rio Grande
HMO, Inc. ("RGHMO"), a wholly owned subsidiary of HCSC. Under the agreement, the
Company  administers  RGHMO's STAR+PLUS  operations in Texas and is responsible,
among other things, for developing and maintaining  RGHMO's provider network and
for  administering  the claims  adjudication and payment  functions.  On July 5,
1997,   RGHMO  entered  into  agreement  for  medical  services  with  Universal
Healthplan,  Inc. ("Universal"),  a Texas health maintenance  organization.  The
agreement  provided for Universal to provide  hospitalization  services to RGHMO
members through Universal's  contract with Tenet Health Care Ltd.  ("Tenet"),  a
hospital chain.  Tenet asserts that RGHMO owes it  approximately  $6,500,000 for
claims allegedly  improperly denied or paid at incorrect rates. On July 1, 1999,
Tenet filed a demand for arbitration  against RGHMO to recover such amounts.  On
March 23, 2000, RGHMO filed a demand for arbitration  against the Company in the
same  arbitration  alleging  that because the Company is  responsible  for claim
adjudication, the Company should be responsible for any amount determined by the
arbitrators  to be due to Tenet.  The  Company  believes  that there is no valid
basis for its inclusion in the arbitration action. The Company also believes its
adjudication of the Tenet claims on RGHMO's behalf was appropriate and Tenet was
paid what it was owed. Accordingly, the Company intends to vigorously assert its
position in this matter.

The  Company  is also a party to  various  claims  and legal  proceedings  which
management  believes  are in the normal  course of business and will not involve
any material loss.

<PAGE>


This HEALTH SERVICES AGREEMENT  ("Agreement") is entered into by and between Rio
Grande HMO,  Inc.  d/b/a HMO  Blue(R),  Southeast  Texas,  a health  maintenance
organization  certified  under Article 20A of the Insurance Code of the State of
Texas  (hereinafter  referred  to as  "HMO"),  and  Lifemark  of Texas,  Inc.  a
nonprofit  health  corporation  certified  under  Section  5.01(a)  of the Texas
Medical Practice Act (hereinafter referred to as "Lifemark Texas").

1     PREAMBLE

      HMO is engaged in the  development,  management  and operation of a health
      maintenance  organization,  one of whose purposes is to provide or arrange
      for comprehensive  health care on a prepaid basis for Medicaid recipients.
      HMO  desires to engage the  services  of  Lifemark  Texas in the  Medicaid
      program. Lifemark Texas desires to participate in the HMO's health service
      delivery  system and directly  provide or arrange  health care services to
      Medicaid  recipients  who have  selected the HMO,  and to provide  certain
      administrative services to HMO.

      Now, therefore,  in consideration of the mutual promises herein stated, it
      is agreed by and between the parties hereto as follows:

2     DEFINITIONS

      The following terms will have the meanings for purposes of this Agreement,
      as set forth below:

2.1   "AGREEMENT" means this contract, including all attachments appended hereto
      and any written amendments subsequently executed by the parties.

2.2   "CLEAN  CLAIM"  means a TDHS  approved  or  identified  claim  format that
      contains all data fields  required by HMO and TDHS for final  adjudication
      of the claim.  The required  data fields must be complete and accurate and
      include HMO-published requirements for adjudication.

2.3   "CONTRACT YEAR" means September 1 of the current year through August 31 of
      the  following  year or as otherwise  defined by the Texas  Department  of

            a decision of HMO on behalf of a Member.

      8.3.5 CONTINUING CARE FOR MEMBERS OF SPECIAL  CIRCUMSTANCE.  Following the
            termination of this Agreement or of any of  Participating  Providers

            behavior,  Lifemark  Texas  or  such  Participating  Provider  shall
            continue to provide treatment to any Member of special circumstance,

            condition  such that Lifemark  Texas or its  Participating  Provider
            reasonably  believes  that  discontinuing  care by  Lifemark  Texas'
            Participating  Provider  could  cause harm to the  Member.  Lifemark
            Texas or its  Participating  Provider  shall  identify  a Member  of
            special  circumstance  to  HMO  and  request  that  such  Member  be
            permitted  to  continue   treatment  under  Lifemark  Texas  or  its
            Participating   Provider's   care,   and   Lifemark   Texas  or  its
            Participating  Provider  shall not seek  payment from such Member of
            any  amounts  for which  the  Member  is not  responsible  under the
            Program.  The  obligations of Lifemark  Texas and its  Participating
            Providers  and HMO under  this  Section  shall  extend  for at least
            ninety  (90) days from the  effective  date of  termination  of this
            Agreement  or beyond  nine months in the case of a Member who at the

            dispute  arising  between  HMO  and  Lifemark  Texas  or  any of its
            Participating   Providers  regarding  the  necessity  for  continued
            treatment by Lifemark Texas Participating Provider shall be resolved
            pursuant to the dispute resolution procedure as provided herein.

            makes  a  formal  recommendation.  If a  physician  or  provider  is

            Lifemark  Texas shall share equally in the "HMO Share" of the excess
            of allowable  HMO STAR+PLUS  revenues  over  allowable HMO STAR+PLUS
            expenses as measured by any  positive  amount for Net Income  Before
            Taxes  of  the  final  Managed  Care  Financial  Statistical  Report
            ("Report").  The amount for Net  Income  Before  Taxes of the Report
            shall  include,   or  be  combined  with,  any  interest  earned  or
            investment  income on Revenue.  No amount  shall be paid to Lifemark
            Texas until TDHS has been paid its experience  rebate, if any, under
            the TDHS Contract. Lifemark Texas's participation in the "HMO Share"
            is contingent upon Lifemark  Corporation's  repayment in full of any
            outstanding notes or loans from HMO. If Net Income  Before  Taxes of
            the Report for any  Contract  Year is a  negative  number,  HMO  and
            Lifemark  Texas shall each  contribute an equal amount to HMO's  CDA
            sufficient to eliminate the deficit within fifteen  (15) days of the
            filing of the Report  with TDHS.  Lifemark  Texas  and  HMO shall be
            paid within fifteen (15) days after filing of the Report their equal
            shares,  if any, of a positive  "HMO Share".  Claims incurred during
            a  Contract  Year  but  paid after  the determination of "HMO Share"
            shall be considered in the risk sharing settlement for the following
            Contract Year.

      9.3.2 ADJUSTMENT.  HMO and Lifemark Texas  acknowledge  that TDHS may make
            adjustments  to Net Income Before Taxes after payment of the amounts
            in Section 9.3.1.  HMO and Lifemark Texas shall repay amounts to the
            CDA which may be due to such adjustment  within fifteen (15) days of
            the determination of the adjustment.


      9.3.3 SECURITY FOR DEFICITS.  As security for Lifemark  Texas's payment of
            any  deficits is described in Section  9.3.1 above,  Lifemark  Texas
            shall purchase a Certificate of Deposit instrument ("Collateral") in
            an amount determined annually by the parties.  Such Collateral shall
            be assigned  to HMO and  pledged in writing  for the HMO's  benefit.
            Such pledge shall be in the form of the agreement attached hereto as
            Addendum  10. The  Collateral  amount  shall be agreed  upon by both
            parties  annually  within ninety (90) days after  commencement  of a
            Contract  Year.  If the parties  cannot agree,  then an  independent
            actuarial  firm shall be selected by mutual  agreement  to determine
            the Collateral  amount.  The parties shall share equally the cost of
            the actuarial  firm.  The actuarial  firm's  recommendation  for the
            Collateral amount shall be binding upon the parties.  The Collateral
            amount for Contract year 2000 is [x]*. The  Collateral  amount shall
            not be changed  until any deficits for the  previous  Contract  Year
            have  been  paid  by  Lifemark  Texas.   The  Collateral   shall  be
            established  within  thirty  (30)  days  of the  execution  of  this
            Agreement.  If the  Collateral  is not  established  by  such  date,
            Lifemark  Texas shall  forfeit  the  Additional  Administrative  Fee
            provided  in EXHIBIT A until the  Collateral  is  established.  This
            provision shall survive the termination of this Agreement.

      9.3.4 SECURITY  EXCEPTION.  If  Lifemark  Texas  obtains  a  Texas  health
            maintenance  organization license, or if Lifemark Corporation or one
            of its affiliates  obtains a Texas health  maintenance  organization
            license and this  Agreement is assigned to such entity,  the parties
            shall determine,  in consultation with TDI, if the Collateral may be
            used to jointly satisfy the  requirements of Section 9.3.3 and TDI's
            minimum net worth requirements for health maintenance organizations.
            If TDI  rejects  such  proposal,  such  entity  shall  maintain  the
            Collateral solely for the purposes of this Agreement. If TDI accepts
            such  proposal,  TDI must agree that HMO will have a first  priority
            lien on the Collateral.

10    TERM AND TERMINATION.

      10.1  TERM. This Agreement shall be effective on December 1, 1999, (though
            it may be finally  executed and  delivered on a subsequent  date) or
            the first day of the month following TDHS approval of this Agreement
            if TDHS must approve the effective  date,  through  August 31, 2001.
            The parties may extend the Agreement by mutual written agreement for
            additional one (1) year periods,  not to exceed two (2)  extensions.
            Each  such  extension  shall be  effective  on  September  1, or the
            effective  date of the Contract  Year between TDHS and the HMO. If a
            party  does not  desire to extend  this  Agreement,  such party must
            provide  the other  party at least one  hundred  twenty  (120)  days
            written  notice prior to the  expiration of the current  term.  Such
            extensions of this Agreement shall be of no force and effect if TDHS
            and HMO do not agree to a Program contract for the extension periods
            of this Agreement.

      10.2 TERMINATION. This Agreement may be terminated upon the following:

            10.2.1 at any time upon the written mutual consent of both parties.

            10.2.2either  party may  terminate  this  Agreement  for a  material
                  breach  or upon the  failure  of either  party to  obtain  and
                  maintain any license,  registration or approval required under
                  State or federal law that is material to the  operation of the
                  Plan Program which has not been cured within 30 days after the
                  "Cure  Period".  The Cure Period is defined as sixty (60) days
                  from the date on which one party receives notice of a material
                  breach from the other party. Provided however, if the material
                  breach involves failure to pay  Administration  Fees when due,
                  the Cure  Period  shall be (10)  days.  If this  Agreement  is
                  assigned to Lifemark Corporation or an affiliate during a Cure
                  Period,  such  assignee  shall be subject to the breach notice
                  and the remaining portion of the Cure Period.

            10.2.3In  the  event  the  contract  between  TDHS  and  the  HMO is
                  terminated  for any reason or the HMO's  participation  in the
                  Program is  otherwise  terminated,  in which case  termination
                  shall be  effective  as of the  termination  date of the HMO's
                  participation in the Program.

            10.2.4Immediately upon the filing of a bankruptcy petition by either
                  party.

10.3  OBLIGATIONS IN EVENT OF TERMINATION.

      10.3.1Upon  termination  of this  Agreement  for reasons  other than those
            described in Section  10.2.2 of this  Agreement,  HMO shall purchase
            those fixed assets and leasehold  improvements  acquired and used by
            Lifemark  Texas  (or  its  subcontractor  Lifemark  Corporation)  to
            administer the HMO at a price equal to the book value of such assets
            as  determined  by  Lifemark  Texas (or its  subcontractor  Lifemark
            Corporation)  at  the  termination  date.  Lifemark  Texas  (or  its
            subcontractor  Lifemark  Corporation)  shall use Generally  Accepted
            Accounting  Principles  (GAAP) for  depreciation of fixed assets and
            leasehold  improvements.  HMO shall also  agree to assume  and/or be
            fully  financially  responsible  for any  lease of  office  space or
            equipment  being  utilized  for  HMO  operations  and  to  indemnify
            Lifemark Texas (or its subcontractor  Lifemark  Corporation) against
            any  liability  therefor.  The purpose of this  reimbursement  is to
            allow the recovery of those costs normally  covered over the life of
            a contract.

      10.3.2In the  event  of  termination  of this  Agreement  for any  reason,
            Lifemark Texas and its subcontractors shall fully cooperate with the
            person or entity  selected  by HMO to assume  administration  of the
            Program.

      10.3.3In the event of termination of this Agreement,  Lifemark Texas shall
            provide  HMO with all copies of records in  Lifemark  Texas's or its
            subcontractor's  Program and which are  necessary  for the continued
            operation  of the  Program,  or  shall  forward  such  records  to a
            successor administrator as directed by HMO.

      10.3.4Upon  termination of this Agreement for any reason,  Lifemark Texas,
            at HMO's option,  shall continue to adjudicate  all incurred  claims
            that had not been  paid as of the  termination  date.  HMO shall pay
            Lifemark Texas a fee of [x]* of the paid claim amount for each claim
            adjudicated.  Lifemark  Texas shall have no obligation to expend its
            own funds to adjudicate  such claims,  but shall deliver such claims
            to the HMO pursuant to the HMO's instructions.  Lifemark Texas shall
            have  no  obligation  to  adjudicate   claims   incurred  after  the
            termination date of this Agreement.

      10.3.5NOTICE OF  WITHDRAWAL.  If HMO determines to withdraw from or limits
            involvement  in the Program,  HMO shall give  Lifemark  Texas ninety
            (90) days prior written notice.  To "withdraw"  shall mean an action
            by HMO to terminate the TDHS Contract,  or HMO's failure or decision
            not to  extend or renew the TDHS  Contract.  To "limit  involvement"
            shall  mean an action by HMO not to expand its  service  area in the
            Program if the HMO is presented such an opportunity. HMO agrees that
            if HMO withdraws or limits its involvement in the Program,  Lifemark
            Texas may pursue such opportunity independently of HMO.

11 MISCELLANEOUS.

11.1  CONFIDENTIALITY. Lifemark Texas agrees to safeguard the confidentiality of
      all data  pertaining to this  Agreement and Covered  Services  rendered to
      Members in accordance with TDHS requirements.

      relationship  of employer  and  employee,  or partners or joint  venturers
      created by this Agreement, and neither party may therefore, make any claim

      compensation benefits, unemployment insurance benefits, vacation pay, sick
      leave or any other  employee  benefit of any kind.  In  addition,  neither
      party shall have any power or  authority to act for or on behalf of, or to

      delegate or subcontract any of its rights or obligations hereunder without
      the prior written consent of the other party.  The parties agree that this
      Agreement  shall  be  assigned  by HMO to  Lifemark  Corporation  or to an
      affiliate of Lifemark Corporation if Lifemark Corporation or the affiliate
      obtains  a Texas  health  maintenance  organization  license.  HMO  hereby
      consents to the  assignment  of the Amended  and  Restated  Administrative
      Services  Agreement  attached  hereto  as  Addendum  11  whereby  Lifemark
      Corporation  shall  perform  certain  administrative  services  for and on
      behalf of Lifemark Texas.

      inserted  merely for the purpose of convenience and do not expressly or by
      implication  limit,  define or extend the specific terms of the section so
      designated.

11.6  WAIVER OF BREACH.  The waiver by either  party of a breach or violation of
      any provision of this Agreement  shall not operate as, nor be construed to
      be, a waiver of any subsequent breach thereof.

11.7  APPLICABLE LAW.  This Agreement shall be governed in all respects by
      the laws of the State of Texas.

                                        29

11.8  INVALID PROVISIONS. If, for any reason, any provision of this Agreement is
      or shall be hereafter determined by law, act, decision, or regulation of a
      duly  constituted body or authority,  to be in any respect  invalid,  such
      determination  shall not nullify any of the other terms and  provisions of
      this Agreement and, unless  otherwise agreed to in writing by the parties,
      then, in order to prevent the  invalidity of such  provision or provisions
      of this  Agreement,  the said  provision  or  provisions  shall be  deemed
      automatically  amended in such respect as may be necessary to conform this
      entire  Agreement  with  such  applicable  law,  act,  decision,  rule  or
      regulation.

11.9  NO THIRD-PARTY BENEFICIARY.  This Agreement is entered into by and between
      HMO and Lifemark Texas and for their benefit. There is no intent by either
      party to create or establish  third-party  beneficiary status or rights or
      their equivalent in any Member,  subcontractor,  or other third party, and
      no such third party shall have any right to enforce any right or enjoy any
      benefit created or established under this Agreement.

11.10 COMPLAINT AND APPEAL  PROCESS.  In the event that any dispute  relating to
      this  Agreement  arises  between  Lifemark Texas and HMO, the parties will
      make a good faith effort to resolve the dispute informally. If the dispute
      cannot  be  resolved  informally,  Lifemark  Texas  must  submit a written
      complaint  to  which  clearly  states  the  basis of the  complaint  and a
      proposed  resolution.  HMO shall  respond  to a written  complaint  to HMO
      within  thirty  (30) days of  receipt,  either  accepting,  rejecting,  or
      modifying Lifemark Texas's proposed  resolution.  This will be HMO's final
      determination.  If the parties  are unable to resolve the dispute  through
      the  complaint   process,   the  dispute  shall  be  resolved  by  binding
      arbitration in accordance with the Rules of Commercial  Arbitration of the
      American  Arbitration  Association.  In no event  may the  arbitration  be
      initiated  more than one year after the date one party first gave  written
      notice of the dispute to the other party. The arbitration shall be held in
      Dallas,  Texas or in such other location as the parties may mutually agree
      upon.  The  arbitrator  shall have no power to award punitive or exemplary
      damages  or vary  the  terms  of this  Agreement  and  shall  be  bound by
      controlling law.

11.11 REVIEW AND AUDIT.  Upon reasonable  notice, or such notice as is permitted
      by federal  or State  authorities,  Lifemark  Texas will at all times make
      available  for  review  and audit by either  the HMO or its  designee  its
      files,  books,  procedures and records (including computer terminal access
      to same)  pertaining  to the Program or the services  provided by Lifemark
      Texas or Lifemark Corporation under this Agreement. In addition,  Lifemark
      Texas  shall  make  available  for  interview  with  HMO's  auditor  those
      personnel with material  involvement or responsibility with respect to the
      services  provided by Lifemark  Texas or Lifemark  Corporation  under this
      Agreement.

11.12 ENTIRE AGREEMENT: AMENDMENT. This Agreement and all exhibits and addendums
      hereto  shall  constitute  the entire  agreement  relating  to the subject
      matter  hereof  between  the  parties  hereto,  and  supersedes  all other
      agreements,  written or oral,  relating to the subject matter hereof. This
      Agreement may be amended by mutual agreement of the parties, provided that
      such amendment is reduced to writing and signed by both parties.

11.13 EXHIBITS.  Any exhibits or  addendums  attached to this  Agreement  are an
      integral part of this Agreement and are incorporated herein by reference.

11.14 STATE GOVERNMENT  APPROVALS.  The parties  acknowledge and agree that this
      Agreement is subject to review and approval by TDI and TDHS.

12    RIGHT OF FIRST  REFUSAL.  HMO  hereby  grants a right of first  refusal to
      Lifemark Texas, Lifemark Corporation,  or a Lifemark Corporation affiliate
      to be the administrative  services manager and health services Provider if
      HMO expands its service area in the Program.  Further, HMO hereby grants a
      right of first  refusal to  Lifemark  Texas,  Lifemark  Corporation,  or a
      Lifemark  Corporation  affiliate,  to enter into an  arrangement  of equal
      sharing of medical risk in the Program,  or any other form of relationship
      in which such risk is shared equally by the parties.  The parties agree to
      negotiate  with each other in good faith as to the  allocation of start-up
      expenses and administrative services fees related to the expansion. If HMO
      declines to pursue the expansion, Lifemark Texas, Lifemark Corporation, or
      a Lifemark Corporation affiliate may pursue the opportunity  independently
      of HMO.

13    NON-COMPETE.  During the term of this Agreement,  Lifemark Texas, Lifemark
      Corporation,  or a Lifemark Corporation affiliate may not compete with HMO
      in the Program, or enter into a contract with an entity that competes with
      HMO  in  the  Program  without  obtaining  HMO's  prior  written  consent;
      provided,  however,  this  restrictive  covenant does not apply to service
      area  expansion in the Program which HMO has declined or failed to pursue.
      Except as set forth above, HMO and Lifemark Texas,  Lifemark  Corporation,
      or a Lifemark Corporation affiliate may pursue independently of each other
      business opportunities which are unrelated to the Program.

      IN WITNESS  WHEREOF,  the  parties  have  executed  this  Agreement  to be
effective as of the day and year first set forth above.

                           pay  Administrative  Fees when due,  the Cure  Period
                           shall be (10) days.

                  4.2.3    In the event the  contract  between TDHS and the Plan
                           is   terminated   for  any   reason  or  the   Plan's
                           participation in the Program is otherwise terminated,
                           in which case  termination  shall be  effective as of
                           the termination  date of the Plan's  participation in
                           the Program.

                  4.2.4    Immediately upon the filing of  a bankruptcy petition
                           by either party.

         4.3      OBLIGATIONS IN EVENT OF TERMINATION.

                  4.3.1    Upon termination of this Agreement for reasons  other
                           than  those  described  in  Section  4.2.2   of  this
                           Agreement,  the  Plan   shall  purchase  those  fixed
                           assets and leasehold improvements acquired  and  used
                           by Lifemark to administer the Plan at  a  price equal
                           to the book value of  such  assets as  determined  by
                           Lifemark at the termination date.  Lifemark shall use
                           Generally  Accepted Accounting Principles  (GAAP) for
                           depreciation   of    fixed   assets   and   leasehold
                           improvements.  The Plan  shall  also  agree to assume
                           and/or  be  fully  financially  responsible  for  any
                           lease of office space  or  equipment  being  utilized
                           for  Plan  operations  and  to   indemnify   Lifemark
                           against any liability therefor.  The  purpose of this
                           reimbursemen  is to allow the recovery of those costs
                           normally covered over the life of a contract.

                  4.3.2    In the event of termination of this Agreement for any
                           reason,  Lifemark  shall  fully  cooperate  with  the
                           person  or  entity  selected  by the  Plan to  assume
                           administration of the Plan.

                  4.3.3    In  the  event  of  termination  of  this  Agreement,
                           Lifemark  shall  provide  the Plan with all copies of
                           records  in   Lifemark'   possession   directly   and
                           specifically  relating to the Plan  Program and which
                           are necessary for the continued operation of the Plan
                           Program, or shall forward such records to a successor
                           administrator as directed by the Plan.

                  4.3.4    If this  Agreement  is  terminated  by the  Plan  for
                           reasons  other  than those  stated in  Section  4.2.2
                           within one year of the Implementation  Date, the Plan
                           will  reimburse  Lifemark  for  [x]*  of all  Program
                           related expenses incurred by Lifemark.

                  4.3.5    Upon  termination  of this  Agreement for any reason,
                           Lifemark,   at  Plan's  option,   shall  continue  to
                           adjudicate all incurred claims that had not been paid
                           as of the termination date. Plan shall pay Lifemark a
                           fee of [x]* of the paid  claim  amount for each claim
                           adjudicated.  Lifemark  shall  have  no obligation to
                           expend its own funds to adjudicate  such  claims, but
                           shall  deliver  such  claims to the Plan  pursuant to
                           the  Plan's  instructions.  Lifemark  shall  have  no
                           obligation  to adjudicate  claims  incurred after the
                           termination date of this Agreement.

         4.4      NOTICE OF WITHDRAWAL.  If the Plan determines to withdraw from
                  or limits  involvement in the Program,  the  Plan  shall  give
                  Lifemark ninety (90) days prior written notice.  To "withdraw"
                  shall mean  an  action  by  the Plan to terminate the contract
                  with TDHS, or the Plan's failure or decision not to  extend or
                  renew the TDHS contract.  To "limit involvement" shall mean an
                  action by Plan not  to  expand its service area in the Program
                  if the Plan is presented such an opportunity.  The Plan agrees
                  that  if  Plan  withdraws  or  limits  its  involvement in the
                  Program, Lifemark may pursue such opportunity independently of
                  the Plan.

                  workers'   compensation   benefits,   unemployment   insurance
                  benefits,  vacation  pay,  sick  leave or any  other  employee
                  benefit of any kind. In addition, neither party shall have any
                  power or  authority to act for or on behalf of, or to bind the

         5.6      WAIVER  OF  BREACH.  The waiver by either party of a breach or
                  violation of any provision of this Agreement shall not operate
                  as, nor be construed to be, a  waiver of any subsequent breach

                  act,  decision,  or  regulation of a duly constituted  body or
                  authority,  to be in  any respect invalid, such  determination
                  shall not  nullify any  of  the other terms and provisions  of
                  this Agreement and, unless otherwise agreed  to  in writing by

                  and between the Plan and Lifemark and for their benefit. There

         5.10     COMPLAINT  AND APPEAL  PROCESS.  In the event that any dispute
                  relating to this Agreement  arises between  Lifemark and Plan,
                  the  parties  will make a good  faith  effort to  resolve  the
                  dispute   informally.   If  the  dispute  cannot  be  resolved
                  informally,  Lifemark must submit a written  complaint to Plan
                  which clearly states the basis of the complaint and a proposed
                  resolution.  Plan shall respond to a written  complaint within
                  thirty (30) days of receipt,  either accepting,  rejecting, or
                  modifying Lifemark's proposed resolution.  This will be Plan's
                  final determination.  If the parties are unable to resolve the
                  dispute  through the complaint  process,  the dispute shall be
                  resolved by binding  arbitration in accordance  with the Rules
                  of  Commercial   Arbitration   of  the  American   Arbitration
                  Association. In no event may the arbitration be initiated more
                  than one year  after the date one  party  first  gave  written
                  notice of the  dispute  to the other  party.  The  arbitration
                  shall be held in Dallas,  Texas or in such other  location  as
                  the parties may mutually agree upon. The arbitrator shall have
                  no power to award  punitive or  exemplary  damages or vary the
                  terms of this Agreement and shall be bound by controlling law.

         5.11     REVIEW AND AUDIT.  Lifemark  will at all times make  available
                  for review and audit by either  the Plan or its  designee  its
                  files,  books,  procedures  and  records  (including  computer
                  terminal access to same) pertaining to the Plan Program or the
                  services  provided  by  Lifemark  under  this  Agreement.   In
                  addition, Lifemark shall make available for interview with the
                  auditor  those   personnel   with  material   involvement   or
                  responsibility  with  respect  to  the  services  provided  by
                  Lifemark under this Agreement.

         5.12     ENTIRE AGREEMENT:  AMENDMENT.  This Agreement and all exhibits
                  hereto shall constitute the entire  agreement  relating to the
                  subject  matter  hereof  between  the  parties   hereto,   and
                  supersedes all other agreements,  written or oral, relating to
                  the subject  matter  hereof.  This Agreement may be amended by
                  mutual agreement of the parties,  provided that such amendment
                  is reduced to writing and signed by both parties.

         5.13     EXHIBITS.  Any  exhibits  attached  to this  Agreement  are an
                  integral part of this Agreement and are incorporated herein by
                  reference.

         5.14     TEXAS  DEPARTMENT OF INSURANCE.  The parties  acknowledge  and
                  agree that this Agreement is subject to review and approval by
                  TDI and TDHS.

         5.15     PLAN INSOLVENCY. Lifemark understands and agrees that Plan has
                  the sole  responsibility  for payment of services  rendered by
                  Lifemark under this Agreement. In the event of Plan insolvency
                  or cessation of  operations,  Lifemark' sole recourse shall be
                  against Plan through the bankruptcy or receivership  estate of
                  Plan.  Lifemark  understands and agrees that neither the State
                  of Texas nor the Plan  Member is  liable  or  responsible  for
                  payment for any services provided under this Agreement.

         5.16     MODIFICATION   TO   AGREEMENT.   Lifemark   agrees   that  any
                  modification,  addition, or deletion of the provisions to this
                  Agreement  will become  effective  no earlier than thirty (30)
                  days after Plan notifies the TDHS of the change.  If TDHS does
                  not  provide  written  approval  within  thirty (30) days from
                  receipt  of  notification  from the Plan such  changes  may be
                  considered provisionally approved.

         5.17     FRAUD AND ABUSE.  This  Agreement  and Lifemark are subject to
                  state and federal fraud and abuse  statutes.  Lifemark will be
                  required to cooperate in the  investigation and prosecution of
                  any  suspected  fraud or abuse,  and must  provide any and all
                  requested  originals  and copies of records  and  information,
                  free of charge,  on  request,  to any state or federal  agency
                  with authority to investigate  fraud and abuse in the Medicaid
                  program.

         5.18     FUNDING.  Lifemark  understands  that  services provided under
                  this  contract  are  funded by State and federal  funds  under
                  the  Texas  Medical  Assistance  Program (Medicaid).  Lifemark
                  is  subject   to   all  State  and  federal  laws,  rules  and
                  regulations that  apply to persons or entities receiving State
                  and federal funds.  Lifemark  understands that  any  violation
                  by Lifemark of a State or federal law relating to the delivery
                  of  services  under  this  contract,  or any violation  of the
                  TDHS/HMO contract could result in liability for contract money
                  damages,  and/or  civil  and  criminal penalties and sanctions
                  under State and federal law.

6.       RIGHT  OF  FIRST  REFUSAL.  The  Plan  hereby  grants a right  of first
         refusal  to  Lifemark to be the administrative services manager if Plan
         expands its service area in  the  Program.  Further,  the  Plan  hereby
         grants  a  right  of  first  refusal  to  Lifemark  or its  affiliates,
         including but not limited to, Lifemark of Texas, Inc., to enter into an
         arrangement  of  equal  sharing  of medical risk in the Program, or any
         other form of relationship in which such risk is shared  equally by the
         parties.  The parties agree to negotiate with each other in good  faith
         as  to  the allocation of start-up expenses and administrative services
         fees  related  to  the  expansion.  If  the Plan declines to pursue the
         expansion,  Lifemark  may  pursue  the opportunity independently of the
         Plan.

7.       NON-COMPETE.  During  the  term of  this  Agreement,  Lifemark  may not
         compete  with Plan in the  Program,  or enter into a  contract  with an
         entity that competes with Plan in the Program without  obtaining Plan's
         prior written consent;  provided,  however,  this restrictive  covenant
         does not apply to service area  expansion in the Program which the Plan
         has declined or failed to pursue.  Except as set forth above,  the Plan
         and  Lifemark  may  pursue   independently   of  each  other   business
         opportunities which are unrelated to the Program.

8.       SETTLEMENT OF  PERFORMANCE  FEE. Plan agrees to pay Lifemark the sum of
         $600,000.00  ("Settlement  Amount") in full and final settlement of the
         Performance  Fee from the  Implementation  Date  through and  including
         November  30, 1999.  Lifemark  accepts the  Settlement  Amount and does
         completely and generally  release,  remise,  and forever discharge Plan
         from any and all claims for Performance Fee for such time period.  This
         release  shall become  effective  and binding upon: a) the execution of
         this Agreement,  and b) the receipt of the Performance Fee by Lifemark.
         Plan  shall pay the  Performance  Fee  within  thirty  (30) days of the
         assignment of this Agreement to Lifemark of Texas, Inc.

                        PERFORMANCE GOALS AND OBJECTIVES

I.       After  120  days  but  before  180  days  after  the end of each of the
         periods,  the   first   of  which  beginning  January  1, 1998  through
         December  31,  1998,  and the next  period  beginning  January  1, 1999
         through  November  30,  1999  ("Performance  Goal Periods"),  Plan will
         calculate the Performance  Fee/Penalty.  Plan will set a gross  medical
         budget which is defined as the sum  of the products  of  the per member
         per month (pmpm) medical  cost target  times the actual  member  months
         for each category.  The pmpm medical cost targets for FY 1998 are shown
         in Exhibit C and will be updated annually.  In  the event that  Medical
         Expenditures fall below [x]* of the gross medical budget, Plan will pay
         Lifemark a Performance Fee in the amount equal to [x]* by Plan  for the
         next  contract  month,  then Lifemark  may elect to pay the Performance
         Penalty to up to twelve (12) equal monthly installments.

II.      In the event that Plan incurs financial  penalties imposed by TDH, TDHS
         or the Texas  Department of Insurance  with respect to the operation of
         the Plan  Program and is a direct  result of the failure of Lifemark to
         fulfill its duties under this  Agreement,  Plan will pay such penalties
         from its own funds,  but may deduct the amount of such  penalties  from
         Lifemark'  Administrative  Fee;  provided  however,  the  amount of the
         deduction shall not exceed [x]*.

III.     This  Exhibit B shall be null and void if Lifemark of Texas,  Inc.  and
         Plan have entered into a risk sharing  arrangement  and this  Agreement
         has been assigned to Lifemark of Texas, Inc.
