2.       SCOPE OF AGREEMENT

         2.1      AHERF Network. On or before the effective date of this
                  Agreement, AHERF shall provide to HealthAmerica a complete
                  list of AHERF Providers as of the date of this Agreement and
                  the usual and customary capitation, percentage of premium or
                  fee schedule under which they are to be paid. If such
                  information is not provided with respect to an AHERF Provider,
                  the fee schedule in the standard provider agreements of the
                  Member Companies will be used to determine payments to such
                  provider. It is generally understood that it may take up to 45
                  days from date of receipt before payments can be processed.
                  The parties understand and agree that AHERF shall as soon as
                  possible use its best efforts to contract and include in its
                  network all physicians who have active medical staff
                  privileges at hospitals that are AHERF Affiliated Providers.

         2.2      Provider Leaving Network. AHERF shall notify HealthAmerica or
                  other Member Company within 10 days of being notified that any
                  AHERF Provider has or will discontinue providing Covered
                  Services to Covered Individuals. If such AHERF Provider is
                  simultaneously discontinuing participation in a HealthAmerica
                  or affiliated product, the parties shall cooperate in
                  transitioning the care of such Covered Individuals to another
                  HealthAmerica Participating Provider within a reasonable
                  amount of time; provided, however, such transfer shall take
                  place immediately if such discontinuance is due to quality of
                  care or HealthAmerica determines that continuation of care may
                  negatively affect care rendered to Covered Individuals.

         2.3      Becoming a HealthAmerica Provider. AHERF shall cause each
                  current or future AHERF Affiliated Provider, and shall make a
                  good faith effort to cause any current or future AHERF
                  Contracted Provider not already participating with
                  HealthAmerica, to apply for participation with the Member
                  Companies in

                  Programs offered within such Provider's service area, and the
                  Member Companies agree to use their best efforts to accept as
                  soon as possible and in any event within 30 days of receipt of
                  a completed application, for participation any such provider
                  that meets the Member Companies' participation criteria and
                  agrees to the Member Companies' contract terms.

                  AHERF shall notify HealthAmerica or other Member Company of
                  any new AHERF Providers and the fee schedule under which such
                  providers are to be paid. If AHERF provides notification to
                  HealthAmerica prior to the 15th day of any month,
                  HealthAmerica shall implement such fee schedule in the
                  following month. In the event that AHERF fails to notify a
                  Member Company of the fee schedule under which a AHERF
                  Provider is to be paid, a Member Company shall pay such
                  provider under the Member Company's then current applicable
                  fee schedule.

                  The parties understand and agree that under no circumstances
                  may an AHERF Provider provide Covered Services hereunder
                  unless it is first accepted by HealthAmerica for participation
                  and agrees to the Member Companies' contract terms.

         2.4      Programs.

                  2.4.1   [___]* The foregoing terms shall be effective upon the
                          later of: (i) the date such provider becomes an AHERF
                          Affiliated Provider: or (ii) the date of this
                          Agreement.

                           submit to HealthAmerica an annual statement signed by
                           AHERF Chief Financial Officer or Treasurer evidencing
                           AHERF's compliance with Section 2.4.  [___]*
                           HealthAmerica shall be entitled to obtain an
                           independent audit of compliance with Section 2.4, the
                           cost of which shall be divided equally between
                           HealthAmerica and AHERF.

         2.5      Termination of a AHERF Provider.

                  2.5.1    In the event of AHERF's termination or suspension of
                           an AHERF Provider's contract with AHERF, AHERF shall
                           immediately cause such AHERF Provider to cease
                           providing Covered Services to Covered Individuals,
                           notify Health America of the foregoing and if the
                           reason for such termination or suspension is required
                           to be reported to the National Practitioner Data
                           Bank, such notice shall state the reason for such
                           termination or suspension.

                  2.5.2    In the event that one of the events listed below
                           occurs as to an AHERF Provider, HealthAmerica may
                           notify AHERF that such Provider is no longer eligible
                           to provide Covered Services to Covered Individuals
                           and AHERF shall thereafter immediately cause such
                           AHERF Provider to cease providing Covered Services to
                           Covered Individuals:

                                        to quality of care or ability to admit

                                        agency or licensing board that may
                                        result in the termination, revocation or
                                        suspension of the Provider's license or
                                        certification.

                                        change in any AHERF Ancillary Provider's

                                        Agreement occurs and HealthAmerica has

                  basis [__]*

         2.10     HealthAmerica Network. AHERF shall take all reasonable steps
                  to maintain in Health America's Western Region network
                  ("Network") the providers listed on Exhibit B attached hereto
                  so long as this Agreement is in effect. The parties hereto
                  understand and agree that those providers listed in Exhibit B
                  with an asterisk associated therewith shall not be removed
                  from the Network except upon the mutual agreement of the
                  designated representatives of the parties comprising the
                  Operating Committee, taking into account quality, location and

                  Member Company desires to add a particular physician or
                  practice group to its physician provider panel, or desires to
                  add physician providers in a particular geographic area within
                  the Western Pennsylvania Region or in a particular type of
                  practice or specialty, it will identify its specific needs in
                  writing to AHERF, including the rationale for the proposed

                           establish compliance with such agreements, and
                           subsequent negotiation or renegotiation of such
                           agreements should be conducted by HealthAmerica

                           to offer to their employees any Program that a Member
                           Company chooses to offer within such AHERF Affiliated
                           Provider's service area on terms, including, without
                           limitation, employer contributions, at least as

                           with comparable benefits and premiums as are offered
                           on behalf of any other third party payor. Such
                           Program(s) shall be offered during each AHERF

                           shall not promote or favor a competing health benefit
                           program with benefits comparable to any Program
                           offered in the AHERF Affiliated Providers' service
                           area so long as the cost to the applicable AHERF
                           Affiliated Provider for the competing health benefit
                           program is no greater than the cost of the Program.
                           In addition, an AHERF Affiliated Provider shall not
                           agree with another third party payor to exclude
                           HealthAmerica or any of its affiliates from the
                           health care benefits offered to the AHERF Affiliated
                           Provider's employees. AHERF shall cause each AHERF
                           Affiliated Provider to immediately inform
                           HealthAmerica in the event that it intends to offer
                           any other third party payor's health benefits plan on
                           terms more favorable than a Program.

                  3.1.6    AHERF shall contract with the Third Parties under or
                           assume as provided in Section 1.2 the terms and

                           with HealthAmerica to provide care to Covered

                           or other Member Company shall be responsible for the

                           Individual, and (ii) the services, supplies, products
                           and accommodation provided to a Covered Individual
                           are Covered Services. The Member Company shall use
                           its reasonable efforts to provide AHERF and AHERF
                           Providers with real time access to the Member

                           reasonable and consistently and uniformly applied to
                           each HealthAmerica Participating Provider.

                           according to its then current policies.

                           As to AHERF Providers being compensated on a
                           capitation basis, if a Covered Individual's
                           eligibility has been canceled retroactively,

                           the AHERF Provider an amount equal to the capitation
                           payments paid to the AHERF Provider on account of
                           such Covered Individual after the date of the
                           retroactive cancellation: provided, however, such
                           amount shall not exceed an amount equal to three (3)
                           months of capitation payments for such Covered
                           Services. The AHERF Provider may bill such Covered

                                    Individuals. AHERF and Member Companies
                                    shall afford Covered Individuals the
                                    opportunity to approve or deny the release
                                    of identifiable personal information by
                                    AHERF or the Member Companies, except where
                                    such release is required by law.

                           4.2.5    Other Duties

                                    4.2.5.1    AHERF shall provide quarterly
                                               performance reports according to
                                               HealthAmerica specifications 
                                               regarding quality improvement 
                                               and utilization management.

                                    4.2.5.2    Representatives from
                                               HealthAmerica shall be included
                                               as voting members of all 
                                               committees of AHERF including
                                               but not limited to the committee
                                               which addresses the development
                                               of quality improvement standards,
                                               provided, such participation
                                               shall be limited to matters
                                               relating to Covered Individuals
                                               and shall not jeopardize any peer
                                               review protection granted under
                                               applicable law.

                           4.2.6    Failure to Perform Delegated Functions to 
                                    the Satisfaction of a Member Company. In the
                                    event that AHERF fails to perform a
                                    Delegated Function in accordance with this
                                    Agreement, a Member Company shall so notify
                                    AHERF, which notice shall set forth in
                                    detail the reasons for such failure. Within
                                    fifteen (15) days of the date of the Member
                                    Company's notice to AHERF, AHERF shall
                                    provide to the Member Company a written plan
                                    for correcting the items detailed in the
                                    Member Company's notice. In the event that
                                    such failure is not corrected within fifteen
                                    (15) days of the date of AHERF's written
                                    plan, the Member Company may notify AHERF
                                    that the Member Company shall perform the
                                    affected Delegated Function and shall
                                    discontinue payment for the same effective a
                                    date certain to be chosen by the Member
                                    Company.

         4.3      Contractual Responsibilities to Covered Individuals. The
                  parties recognize that regulatory requirements provide that
                  HealthAmerica and other Member Companies will remain
                  ultimately responsible to Covered Individuals, financially or
                  otherwise, for AHERF's functions and responsibilities under
                  the terms of this Agreement and that HealthAmerica will retain
                  oversight authority over such functions and responsibilities.

5.       FINANCIAL TERMS.

         5.1      Financial Responsibility. All Covered Services rendered for
                  Covered Individuals are to be either directly provided by or
                  paid for by AHERF. AHERF shall be responsible for the total
                  costs of Covered Services whether provided within or outside
                  of AHERF's system. Covered Services for which AHERF shall be
                  financially responsible will include without limitation
                  Emergency Medical Services or Urgently Needed Services.



                                       18

         5.2      Percent of Premium. In consideration of AHERF's arranging for
                  the provision of Covered Services to Covered Individuals under
                  the Programs, its assumption of risk of financial loss
                  associated with the provision of those Covered Services and
                  its performance of the other duties set forth in this
                  Agreement, HealthAmerica or a Member Company, as appropriate,
                  shall pay AHERF the AHERF Premium Amount, subject to
                  applicable terms and conditions set forth elsewhere in this
                  Agreement.

                  If the average per member, per month premium in a Risk Year
                  for the aggregate of Covered Individuals enrolled in a Program
                  is more than two percent (adjusted for change in benefit
                  design and demographic mix) less than the average per member,
                  per month premium for the previous Risk Year for the aggregate
                  of Covered Individuals enrolled in such Program, the parties
                  hereto shall negotiate in good faith to execute and deliver a
                  mutually satisfactory amendment to this Agreement to adjust
                  the percent of premium paid to AHERF hereunder for such
                  Program, subject to Section 2.5.1.
                  
         5.3      Reconciliation. The parties understand and agree that because
                  the percentage of premium allocated to AHERF differs for each
                  Program, the calculations and reconciliations under this
                  Section 5 shall not be aggregated and shall be made separately
                  for the Commercial HMO Program, the Medicare Risk HMO Program,
                  the PPO Program and POS Program and, if implemented, the
                  Medicaid HMO Program and the Private Label Program.

         5.4      Interim Premium Reconciliation. In order to facilitate prompt
                  reconciliation of differences between amounts paid and amounts
                  owed between the parties during each Risk Year, the Member
                  Companies shall perform interim premium reconciliations for
                  each of the first three quarters of each Risk Year ("Interim
                  Reconciliation Periods") commencing on the effective date.
                  Within one hundred thirty five (135) days after the end of
                  each Interim Reconciliation Period, the Member Companies shall
                  calculate the difference between (i) the AHERF Premium Amount
                  for such Interim Reconciliation Period plus any payments made
                  by AHERF pursuant to Section 5.10.6 ("Shortfall Payments") and
                  (ii) the amount of Total Provider Payments incurred by the
                  Member Company for services provided during such Interim
                  Reconciliation Period plus an amount for claims incurred but
                  not reported ("IBNR"), calculated consistently with the Member
                  Company's other IBNR claims calculations, less any amounts
                  recovered by AHERF from an applicable reinsurer (the "Interim
                  Premium Reconciliation Amount"). Detailed lag schedules
                  relating to the IBNR calculation will be provided with each
                  reconciliation, with the intention to migrate to an AHERF
                  specific IBNR calculation where practically feasible. There
                  will be no interim payments due to or from either party in the
                  initial year. Subsequent years will include a provision



                                       19

<PAGE>   20



                  for interim payments only if the final reconciliation for the
                  prior year resulted in an amount due to and from either party
                  in excess of ten percent (10%) of the total premium for that
                  period. If the Interim Premium Reconciliation Amount is a
                  positive number the Member Company shall pay that amount to
                  AHERF within fifteen (15) days of the completion of the
                  reconciliation. In the event the Interim Premium
                  Reconciliation Amount is a negative number AHERF shall pay
                  that amount to the Member Company within fifteen (15) days
                  after receipt from the Member Company of the results of the
                  reconciliation.

         5.5      Annual Premium Reconciliation. Within one hundred eighty (180)
                  days after the end of each Risk Year, HealthAmerica shall
                  calculate the difference between (i) the AHERF Premium Amount
                  plus Shortfall Payments in the Risk Year and (ii) the amount
                  of Total Provider Payments made by Member Companies for
                  services provided to Covered Individuals during such Risk Year
                  plus IBNR claims less any amounts recovered by AHERF from an
                  applicable reinsurer (the "Premium Reconciliation Amount").
                  Upon completion of the reconciliation, the parties agree to
                  meet and review the results and supporting documentation.
                  Either party may perform further diligence in the sixty (60)
                  days following presentation of the reconciliation. Absent
                  material differences, the party owing the other shall pay one
                  hundred percent (100%) of the amount due by the end of the
                  sixty (60) day period. Any claims presented to a Member
                  Company for payment following completion of the Annual Premium
                  Reconciliation for a given Risk Year shall be entirely AHERF's
                  financial responsibility, paid by the Member Company and
                  reimbursed through the Account.

         5.6      Final Premium Reconciliation. In the event of termination of
                  this Agreement a Member Company shall within twenty-four (24)
                  months of the effective date of termination calculate for any
                  periods for which Premium Reconciliation Amounts have not
                  already been calculated and paid (the "Final Reconciliation
                  Period") the difference between: (i) the AHERF Premium Amount
                  plus Shortfall Payments for such Final Reconciliation Period
                  and (ii) the amount of Total Provider Payments made by the
                  Member Company for services provided to Covered Individuals
                  during the Final Reconciliation Period plus IBNR claims,
                  calculated consistently with the Member Company's other IBNR
                  claims calculations for such Final Reconciliation Period less
                  any amounts recovered by AHERF from an applicable reinsurer
                  not already calculated (the "Final Premium Reconciliation
                  Amount"). Any Final Premium Reconciliation Amounts owed by
                  either party shall be paid within ninety (90) days of receipt
                  of notice of the Final Premium Reconciliation Amount. Any
                  Premium Reconciliation Amounts previously calculated as due
                  from one party to the other, but not yet paid, shall be paid
                  at the same time.

         5.7      Supporting Information; Audit.  Within one hundred eighty 
                  (180) days after the end of each Risk Year and within 180 days
                  of the effective date of termination of

                  this Agreement, the Member Companies shall provide to AHERF
                  information establishing: (i) the Total Premium in respect of
                  such Risk Year; (ii) the Total Provider Payments in respect of
                  such Risk Year; and (iii) the Member Company's calculation of
                  the AHERF Premium amount and the Premium Reconciliation for
                  such Risk Year. AHERF shall be entitled to review and to
                  conduct an audit (either by AHERF or by independent auditors
                  acceptable to HealthAmerica) of the Member Company's books and
                  records to verify such amounts and calculations as claimed by
                  the Member Company. The cost of any such review and/or audit
                  conducted by independent auditors shall be shared equally
                  between the Member Company and AHERF. If, as the result of any
                  such review or audit, it is determined that the Premium
                  Reconciliation as conducted by the Member Company was
                  incorrect, AHERF and HealthAmerica shall promptly correct the
                  Premium Reconciliation. In the event AHERF and the Member
                  Company are unable after good faith efforts for at least 60
                  days to resolve a dispute with regard to any such amount or
                  calculation, such dispute shall be settled in accordance with
                  the dispute resolution provisions of this Agreement.

         5.8      Insurance. Each party shall secure and maintain or cause to be
                  secured and maintained comprehensive general professional and
                  directors and officers liability insurance through a program
                  of self-insurance or through the purchase of insurance
                  providing minimum limits of liability of the greater of (i)
                  one million dollars ($1,000,000) per claim and three million
                  dollars ($3,000,000) in the annual aggregate or (ii) such
                  amount as shall be required by law covering the acts or
                  omissions of itself, its employees, officers and agents within
                  the scope of and during the term of this Agreement. Each party
                  shall provide the other with proof of the foregoing on written
                  request. In addition AHERF shall secure and maintain
                  reinsurance policies (also known as stop-loss insurance) to
                  insure costs of health care services required for specific
                  cases at least to the minimum amounts required by law or set
                  forth in HFCA physician incentive plan regulations and shall
                  report to the Member Companies recoveries on such policies as
                  provided under the reconciliation provisions above and the
                  premiums on such policies as provided in 5.10.4 below.

         5.9      No Balance Billing. AHERF hereby agrees that in no event,
                  including but not limited to, non-payment by a Member Company,
                  a Member Company insolvency or breach of the Agreement, shall
                  AHERF bill, charge or collect a deposit from, seek
                  compensation, remuneration or reimbursement from, or have any
                  recourse against, Covered Individuals or persons other than a
                  Member Company acting on their behalf for Covered Services.
                  This Section shall not prohibit collection of Copayments,
                  Coinsurance, Deductibles or Financial Penalties made in
                  accordance with the terms of the applicable Covered
                  Individual's contract with a Member Company nor billing for
                  non-Covered Service for which Covered Individuals have had
                  prior notification and approved.



                                       21

<PAGE>   22



                  AHERF further agrees that: (i) the no balance billing
                  provision herein shall survive the termination of the
                  Agreement regardless of the cause giving rise to termination
                  and shall be construed to be for the benefit of Covered
                  Individuals; and (ii) this no balance billing provision
                  supersedes any oral or written contrary Agreement now existing
                  or hereafter entered between AHERF and a Covered Individual or
                  a person acting on his/her behalf.

                  Any modification, addition or deletion to the provisions of
                  this Section shall become effective on a date no earlier that
                  sixty (60) days after the Pennsylvania Secretary of Health has
                  received written notice of such proposed change.

         5.10     Assurances of Claims Payment.

                  5.10.1   Controlled Disbursement Account.  On or before the 
                           effective date of this Agreement, AHERF shall open
                           one or more interest bearing bank accounts, over
                           which HealthAmerica or the appropriate Member Company

                           provided to Covered Individuals (such administrative
                           expenses and reinsurance premiums are hereinafter
                           collectively referred to as "Expenses"); and (iii) if
                           not otherwise previously paid, capitation payments
                           due to providers other than primary care physicians
                           for Covered Services ("Other Capitation Payments").
                           Within fifteen (15) days of its receipt of such
                           notice the Member Companies shall withdraw from the
                           Account and forward to AHERF an amount equal to the
                           amount set forth in such notice, provided: (i)
                           Expenses are substantiated by AHERF by third party
                           invoice, contract or some other form of reliable
                           documentation; (ii) the notice lists the providers
                           that shall receive Other Capitation Payments and the
                           amounts to be received by such providers; and (ii)
                           such amount does not exceed ten percent (10%) of the
                           previous monthly deposit to the Account.

                  5.10.5   Restriction of Account Funds.  The Member Companies 
                           shall not withdraw moneys from the Account other than
                           for the purposes described in Section 5 of this
                           Agreement.

                  5.10.6   Account Shortfall.  In the event that moneys in the 
                           Account do not exceed 15 days of the daily average of
                           total claims for the preceding three (3) month
                           period, the Member Companies shall immediately notify
                           AHERF which notice shall include the amount of such
                           insufficiency (the "Shortfall"). Within three
                           business days of the receipt of such notice, AHERF
                           shall deposit in the Account an amount equal to the
                           Shortfall. Failure to make such payment within such
                           time period shall constitute a material breach under
                           Section 7.2.2. The obligation hereunder shall survive
                           termination of this Agreement.

                  5.10.7   Reimbursement. Within ten (10) days of its receipt
                           of notice from the Member Companies, AHERF shall

                           reasonable administrative expenses incurred by the
                           Member Companies, as mutually determined, due to
                           AHERF's failure to pay any Shortfall amounts,
                           including, without limitation, expenses incurred as a
                           result of processing duplicate claims.

                  5.10.8   Reconciliations. Any amounts required to be paid
                           under Section 5 of this Agreement shall first be paid
                           out of any amounts remaining in the Account in excess
                           of the then due and outstanding Claims and Other
                           Capitation Payments. Any amounts remaining in the
                           Account after performance of all of the
                           reconciliations required under this Section 5 shall
                           be the property of AHERF.

                             continue to be provided all Covered Services by an
                             AHERF Provider, and HealthAmerica shall pay such
                             AHERF Provider for such inpatient Covered Services
                             in accordance with this Agreement until such
                             Covered Individual is transferred to another
                             facility per HealthAmerica's request or is properly
                             discharged.

                  7.3.3      Continuation of Payment.  Within one hundred eighty
                             (180) days of the end of the Continuation Period,
                             HealthAmerica or another Member Company shall pay 
                             the AHERF Providers all sums due and outstanding112
                             for services rendered to Covered Individuals 
                             between the date of termination of the Agreement 
                             and the end of the Continuation Period. For
                             services rendered during that period, or another 
                             Member Company agrees to pay the AHERF Providers at
                             the rates in effect at the time of termination of 
                             the Agreement to the extent such services would
                             have been Covered Services had this Agreement not 
                             been terminated.

                  7.3.4      Direct Contracting with Affiliated Providers.  A 
                             Member Company or another Member Company may 
                             recruit and contract directly with AHERF Providers
                             to provide Covered Services upon the commencement
                             of the Continuation Period. In any case such
                             contracts by and between the Member Company and
                             AHERF Providers shall not become effective until
                             the termination of this Agreement. AHERF shall not
                             take any action to prevent AHERF Providers from
                             contracting directly with HealthAmerica or a
                             Member Company.

                  7.3.5      Nondisclosure. Neither party shall discuss the
                             circumstances of the termination of this Agreement
                             with third parties or refer to the other party
                             hereto in any negative or disparaging manner or in
                             any way which may negatively affect the image or
                             reputation of the other party. Further, AHERF will
                             take reasonable steps to prevent AHERF Providers
                             from making any such references to a Member
                             Company.

                  7.3.6      ISS. The Member Companies shall continue to provide
                             AHERF and AHERF Providers with all applicable
                             information support services as required by this
                             Agreement during the Continuation Period.

                  7.3.7      Risk Assumption. Upon the termination of this
                             Agreement for any reason, the risk assumption by
                             AHERF under the procedures described in Section 5
                             shall apply up to and including such date of
                             termination. Upon the termination of this
                             Agreement, AHERF and the Member Companies shall
                             cooperate in good faith to cause an orderly wind up
                             of



                                       28

                             the operations contemplated by this Agreement so as
                             not to cause unnecessary disruption to Covered
                             Individuals or AHERF Providers. Termination of this
                             Agreement has no effect upon the rights,
                             obligations or remedies at law or in equity of the
                             parties under any other Agreement.

                             Upon termination of this Agreement and subject to
                             applicable law regarding confidentiality of medical
                             records, each party shall for a period of seven (7)
                             years from the date of termination provide the
                             other party with full access to (and such other
                             party shall be entitled to make and use
                             computer-readable and hard copies of) all data and
                             information of the first party relating to the
                             Member Companies members developed during the term
                             of this Agreement relating to (i) the performance
                             by AHERF Providers under the UM/QA program and (ii)
                             claims, utilization, case management, payment and
                             outcome data with respect to each Covered
                             Individual provided any Covered Services during the
                             term of this Agreement. During the Continuation
                             Period and thereafter, each party shall have the
                             unrestricted ability to contact or otherwise have
                             access to all such Covered Individuals provided the
                             other party does not in any manner disparage the
                             other party (or any AHERF Provider) or any products
                             or services of such other party (or any AHERF
                             Provider).

8.       CONFIDENTIALITY.

         8.1      The parties recognize and acknowledge that performance of this
                  Agreement and related provider agreements shall result in the
                  disclosure to the other party of trade secrets, proprietary
                  information and confidential information including this
                  Agreement and its terms, conditions and financial terms and
                  schedules (collectively referred to as "Confidential
                  Information"). The non-disclosing party agrees that it and its
                  owned, controlled or managed entities and their employees,
                  representatives and agents, shall treat Confidential
                  Information as strictly confidential and shall:

                  8.1.1      protect the Confidential Information from 
                             unauthorized use or disclosure, either directly or
                             indirectly, and keep it confidential;

                  8.1.2      use the Confidential Information only for purposes 
                             related to this Agreement;

                  8.1.3      not disclose or otherwise permit any third person 
                             or entity access to the Confidential Information
                             without prior written authorization by the
                             disclosing party; and



                                       29

<PAGE>   30

                  8.1.4      limit disclosure to necessary individuals and
                             ensure that individuals exposed to Confidential
                             Information are advised of its confidential nature
                             and their obligations thereunder.

         8.2      Information shall not be considered to be Confidential 
                  Information if:

                  8.2.1      it is already, or otherwise becomes, publicly known
                             by third persons other than as a result of an act
                             or omission of the non-disclosing party;

                  8.2.2      it is lawfully received from a third person having 
                             the right to disseminate the information without
                             restriction on disclosure;

                  8.2.3      it is furnished to others by the disclosing party 
                             without restriction on disclosure;

                  8.2.4      it can be shown by the receiving party to have been
                             independently developed by such party; or

                  8.2.5      it is required to be disclosed by law or court
                             order.

         8.3      This Section 8 shall survive termination of this Agreement.
                  The parties agree that the breach or prospective breach of
                  this provision will cause irreparable harm for which money
                  damages may not be adequate. The parties therefore agree that
                  in addition to any other remedies, the non-breaching party
                  shall be entitled to injunctive or other equitable relief to
                  restrain the breach hereof.

9.       RESTRICTIVE COVENANTS.

         9.1      Restriction on AHERF Activities

                  So long as this Agreement is in effect and for a period of one
                  year following its termination, AHERF will not, and will cause
                  any subsidiary or affiliate of AHERF to not offer, and to not
                  own a controlling interest in, manage or otherwise direct or
                  control any entity which offers, any health care benefits plan
                  on a direct or "retail" basis (including on an employer
                  self-funded or self-insured basis) to employers or other
                  purchasers of health care services in AHERF's aggregate
                  service area or in the geographic area in which HealthAmerica
                  presently engages in the offering of health care benefit
                  plans, other than to the employees of AHERF or any AHERF
                  provider. The foregoing sentence shall not prohibit AHERF or
                  any AHERF subsidiary or affiliate from providing or arranging
                  to provide health care services on a risk or non-risk basis
                  under any product of any other health maintenance
                  organization, preferred provider organization or other entity,
                  and AHERF's or its affiliates' continued passive ownership
                  interest of Gateway and Health Partners (so long as such
                  interest shall not be increased materially from that existing
                  on the date of this agreement, or constitute a controlling
                  interest).

         9.2      Restrictions on HealthAmerica Activities

                  So long as this Agreement is in effect and for a period of one
                  year following its termination, Coventry and HealthAmerica
                  agree that Coventry and HealthAmerica will not, and will cause
                  each of their subsidiaries to not, provide healthcare services
                  directly to the public, or acquire practices which provide
                  such services to the public within the service area of the
                  AHERF Affiliated Providers (except in the Central Pennsylvania
                  Region).

         9.3      This Section 9 shall survive termination of this Agreement.
                  The parties agree that the breach or prospective breach of
                  this provision will cause irreparable harm for which money
                  damages may not be adequate. Therefore, the parties agree that
                  in addition to any other remedies, the non-breaching party
                  shall be entitled to injunctive or other equitable relief
                  without being required to post bond.

10.      NO SOLICITATION.

         So long as this Agreement is in effect and for a period of two (2)
         years after the date of termination of this Agreement (whether for
         material breach or for other cause or by expiration of the term)
         neither party shall directly or indirectly in any capacity whatsoever
         solicit, attempt to solicit or encourage any person who was employed by
         the other party on a full or part-time basis while this Agreement is in
         effect or to encourage such person to leave the employ of the other
         party hereto without the prior written consent of the other party. For
         purposes of this Agreement, indirect solicitation shall not include
         advertising in professional journals and newspapers provided the party
         so advertising does not request or advise such employee to make
         application for such advertised positions.

11.      COOPERATION OF THE PARTIES.

         11.1     AHERF and the Member Companies will maintain an effective
                  liaison and close cooperation with each other to provide
                  maximum benefits at reasonable costs to Covered Individuals
                  consistent with high standards of medical practice. AHERF and
                  the Member Companies will comply with the others
                  administrative policies and procedures including those related
                  to the delivery of medical services and will keep and make
                  available such medical, financial and other records as each
                  party requires for Covered Individuals.

         11.2     AHERF agrees, and will cause AHERF Affiliated Providers to
                  ensure, that each Primary Care Physician shall remain open to
                  Covered Individuals during the term of this Agreement. This
                  provision shall not apply when both parties have



                                       31

<PAGE>   32



                  reasonably determined that a particular office has reached its
                  capacity provided that:

                  11.2.1     the office is closed to all new patients; and

                  11.2.2     AHERF demonstrates that the physician office is
                             attempting to hire additional staff/physicians in
                             order to increase capacity, if feasible.

         11.3     The Member Companies will provide AHERF with relevant
                  information to assist AHERF in evaluation of potential
                  physician offices for acquisition to the extent permitted
                  under applicable contracts and regulations.

         11.4     The Member Companies will provide advance copies of relevant
                  Member Company policies and procedures and updates to AHERF as
                  applicable.

         11.5     The foregoing shall not prevent an AHERF Affiliated Provider
                  that is a physician from terminating his/her relationship with
                  a Covered Individual provided that such termination is not due
                  to age, race, color, creed, religion, sex, sexual preference,
                  national origin, health status, income level, credit history,
                  or on the basis that he/she is a Medicare or Medicaid
                  beneficiary or enrolled in a prepaid health plan. By way of
                  explanation of the foregoing and not by limitation, such
                  physician shall not terminate his/her relationship with a
                  Covered Individual due to the amount of Medically Necessary
                  Covered Services required by the Covered Individual.

12.      AGREEMENT ADMINISTRATION.

         12.1     Operating Committee. The parties shall designate an Operating
                  Committee to oversee the operation of this Agreement and the
                  related provider contracts. The Operating Committee shall
                  consist of equal representation from Coventry/HealthAmerica/
                  Member Companies (as a single party) and AHERF. The Operating 
                  Committee shall meet no less than quarterly. The Committee 
                  shall have the authority to create temporary committees 
                  necessary for the implementation and/or effective operation of
                  this Agreement.

         12.2     Dispute Resolution. If any dispute or controversy shall arise
                  between the parties hereto with respect to the making,
                  construction, terms, or interpretation of this Agreement; or
                  the rights of any party hereto; or with respect to any
                  transaction involved; the Operating Committee shall make good
                  faith efforts to settle the dispute or controversy. If the
                  Operating Committee is unable to resolve such dispute within
                  60 days, the Operating Committee shall request the President
                  of each party (or his or her designee) to resolve the dispute
                  and, if the Operating Committee is able to agree, make
                  recommendations of possible resolution methodologies to the
                  Presidents.

13.      SEVERABILITY.

         In the event that any provision of this Agreement conflicts with the
         law under which this Agreement is to be construed, or if any such

                  identifying in the aggregate all payments made or owed to its
                  providers in sufficient detail for West Virginia HMO and the
                  Commissioner to determine if the payments are being made in a
                  timely manner and which identify in the aggregate the
                  reasonably estimated incurred but not reported health care
                  costs. West Virginia HMO shall monitor said reports referred
                  to in this Section 3.1.9.

                  3.1.10 AHERF shall permit West Virginia HMO and the
                  Commissioner, both singularly and jointly, upon reasonable
                  prior notice, to audit, inspect and copy its books, records,
                  and other evidence of its operations which are, in the
                  discretion of West Virginia HMO or the Commissioner, relevant
                  to AHERF's obligations under the Agreement for the purpose of
                  determining its compliance with all requirements legally
                  mandated by statute, rule or the Agreement. Any review is
                  subject to any confidentiality requirements imposed by State
                  or Federal law.

                  Member Company is required to retain oversight of the
                  Delegated Functions. A Member Company shall not be required to
                  delegate a Delegated Function hereunder unless and until the
                  Member Company and AHERF mutually agree to the frequency and
                  content of periodic reports to be provided by AHERF to the
                  Member Company in order to assist HealthAmerica in performing
                  its oversight duties hereunder. A Member Company shall conduct
                  an annual on-site audit of AHERF to ensure compliance with
                  HealthAmerica's, or Member Company's Pennsylvania's, Ohio's or

8.   Section 4.2.1.4, STANDARD OF PERFORMANCE, shall be revised to read as
     follows:

                  "All Delegated Functions shall be performed in accordance with
                  standards satisfactory to the Member Company, which standards
                  shall be no less than the standards required by NCQA, the
                  Pennsylvania Department of Health ("DOH") or the Pennsylvania
                  Insurance Department ("DOI"), including, without limitation,
                  the requirements set forth in the DOH's Statement of Policy
                  and the DOI's Statement of Policy, each as amended from time
                  to time, respectively set forth at 28 Pa. Code '9.401 et seq.
                  and 31 Pa. Code '301.301 et seq. (collectively the "Statement

                  Further, all Delegated Functions shall be subject to
                  performance monitoring by the Member Company and the DOH,

                  independent quality review/assessment approved by the DOH,
                  the State of Ohio and the State of West Virginia.
                  HealthAmerica or Member Company may elect to rescind any
                  delegated duties if, in HealthAmerica's or Member Company's
                  sole opinion, AHERF's performance of such functions may
                  jeopardize either the health or safety of HealthAmerica's or
                  Member Company's members, or HealthAmerica's or Member
                  Company's compliance with applicable regulations or other
                  certification requirements."

9.    Section 4.2.3, ACCESS TO RECORDS, shall be amended to read as follows:

                  insolvency or breach of the Agreement, shall AHERF bill,
                  charge or collect a deposit from, seek compensation,
                  remuneration or reimbursement from, or have any recourse
                  against, Covered Individuals or persons other than a Member
                  Company acting on their behalf for Covered Services. This
                  Section shall not prohibit collection of Copayments,
                  Coinsurance, Deductibles or Financial Penalties made in
                  accordance with the terms of the applicable Covered
                  Individual's contract with a Member Company nor billing for
                  non-Covered Service for which Covered Individuals have had

                  a person acting on his/her behalf.

                  "Any modification, addition or deletion to the provisions of
                  this Section shall become effective on a date no earlier that
                  sixty (60) days after the Pennsylvania Secretary of Health and

                                    SECTION 3
                               OBLIGATIONS OF BJC

3.1  PROVIDER REQUIREMENTS: BJC shall arrange for BJC Providers to provide
Covered Services to all Members regardless of the type of Benefit Plan or Payor
covering such Member and regardless of the frequency or degree such Members
utilize Covered Services. BJC shall, and shall use its best efforts to cause BJC
Providers to, cooperate with all medical management, utilization management,
credentialing, quality assessment, peer review, or other similar programs
established by Plan and/or by BJC under this Agreement. BJC shall use its best
efforts to assure that BJC Providers comply with all applicable obligations set
forth in this Agreement and BJC shall assure that BJC Providers comply with the
member protection/no balance billing provisions set forth in this Agreement,
with applicable obligations set forth in BJC Provider Agreements, including
without limitation the following:


         (1) BJC Providers shall provide Covered Services to all Members, and
         shall accept all Members as new patients in accordance with the terms
         of this Agreement and at least on the same basis as BJC Provider is
         accepting non-Members as new patients without regard to type of Benefit
         Plan or Payor, race, religion, gender, color, national origin, age or
         physical or mental health status.

         In addition, BJC agrees that each of the Medical Centers shall remain
         adequately staffed with BJC Providers and BJC PCPs to provide
         continuous capacity to serve no less than 1000 Members per Medical
         Center in addition to the number of Members served as of the Effective
         Date. Employed, owned, and controlled BJC Providers (including those

                                       5

<PAGE>   6


         (2) BJC Provider may inquire regarding the current status of the
         Member's eligibility for Covered Services by requesting presentation by
         the Member of his or her identification card or by contacting Plan
         during normal office hours. However, if Plan subsequently learns or
         determines that the individual was not eligible for coverage for the
         services rendered, those services shall not be eligible for payment
         under this Agreement. BJC Provider may then directly bill the
         individual for such services. Notwithstanding the foregoing, in the
         event Plan confirms eligibility to a BJC Provider after 45 days
         following the effective date for the eligibility change, and BJC and
         BJC Provider use reasonable efforts to collect its fees for such
         services using customary collection practices (to include at least
         billing the Member through 2 billing cycles) and is unsuccessful in
         collecting such amounts from the Member, BJC and BJC Provider may
         submit such claims to Plan for payment at a rate of 50% of the fee
         schedules set forth in Exhibit A-4.

         (3) BJC Provider shall comply with protocols of Plan and/or BJC,
         including without limitation the following:

                  (i)   Referral of Members only to other Participating
                  Providers or BJC Providers unless otherwise authorized by Plan
                  and BJC pursuant to the Member's Benefit Plan.

                  (ii)  Compliance with approved billing procedures of Plan.

                  (iii) Obtain prior authorization and/or precertification for
                  certain Covered Services as defined by Plan.

                  (iv)  Compliance with any provider administrative manual,
                  credentialing plan or contracting standards, as modified from
                  time to time by Plan and/or BJC.

         (4) If the Member's Benefit Plan requires the Member to receive all or
         any Covered Services from or upon Referral Authorization by a PCP or
         Plan, the following additional protocols must be adhered to when those
         Covered Services are provided by ancillary and referral providers and
         Referral Physicians: (i) Referrals to other Participating Providers,
         non-Participating Providers, and BJC Providers must first be authorized
         by the Member's PCP (or for Medicaid Members, by HCUSA); and (ii)
         Covered Services must be provided pursuant to the terms and limitations
         of the Referral Authorization issued by or on behalf of the Member's
         PCP or by HCUSA, as applicable.

         (5) BJC Provider shall comply with the following requirements for
         admitting Members to a hospital:

                  (i)   Admit Members on the day of surgery, unless the Member's
                  medical condition requires otherwise and BJC Provider has
                  obtained prior authorization from Plan.


                                       6

<PAGE>   7


                  (ii)  Notify Plan by telephone prior to a scheduled authorized
                  admission of a Member.

                  (iii) In the event of an Emergency admission under the
                  direction of BJC Provider, notify Plan within 24 hours of the
                  admission or, for admissions occurring during a weekend or
                  holiday, by the end of the first working day thereafter.

                  (iv)  If BJC Provider is a Referral Physician and the Member's
                  Benefit Plan requires the Member to receive all or any Covered
                  Services from or upon Referral Authorization by a PCP or Plan,
                  such BJC Provider also must notify the Member's PCP of all
                  admissions and comply with applicable Plan required protocols
                  when those Covered Services are provided.

         Failure to comply with the protocols of Plan may result in sanctions
         against BJC Provider, including without limitation loss of
         reimbursement to BJC in accordance with the performance standards and
         sanctions set forth in EXHIBIT G, and upon repeated failure to comply
         by a specific BJC Provider, sanctions up to and including termination
         of that BJC Provider's participation under this Agreement as set forth
         in EXHIBIT G.

         (6) BJC Provider and BJC shall cooperate with the Plan's (and for
         Medicaid Members, with the State of Missouri's) coordination of
         benefits, third party claims recovery and subrogation rules to the
         extent permitted by law.

3.2 PAYMENT TO PROVIDERS. BJC shall be solely financially responsible for the
compensation remitted to BJC Providers and Participating Providers for all
Covered Services rendered to BJC Members whether provided in or outside of
Plan's Service Areas and BJC's Service Sites. BJC shall and shall ensure that
BJC Providers hold harmless and indemnify Plan and Payor against any claims for
compensation by a BJC Provider. BJC shall hold harmless and indemnify Plan and
Payor against any claims for compensation by a Participating Provider for
Covered Services for which GHP has made payment to BJC out of the Claims Payment
Account. BJC shall and shall assure that Providers provide Plan with Referral
Authorizations and other information required for Plan to process and reconcile
claims presented for payment by Providers within no later than 60 days from the
date of service. Failure to submit claims within 90 days of the date of service
or inpatient discharge may result in BJC and BJC Providers forfeiting the right
to payment for such claims (member protection provisions in Section 5 below
apply). The process by which BJC Providers and Participating Providers are paid
shall comply with the terms and conditions set forth in this Agreement
(including without limitation Section 3.4 and Section 3.1) and in EXHIBIT A-1,
AND A-2, A-3, AND A-4.

3.3 PROVIDER PARTICIPATION. BJC shall require that its BJC Providers who are
PCPs participate solely with BJC for the purpose of rendering Covered Services
to Members. BJC shall notify Plan promptly in the event it knows or becomes
aware of PCPs who participate with more than one (1) medical group, IPA or PHO
for the purpose of rendering Covered Services to Members. The parties understand
and agree that BJC shall as soon as possible after the Effective


                                       7

<PAGE>   8


Date but not later than October 1, 1997 use its reasonable efforts to contract
and include in its network all physicians that are affiliated or under contract
with BJC. Notwithstanding anything herein to the contrary, Plan may request that
BJC recruit and, if such physician meets BJC criteria, accept as a BJC Provider
a specific physician(s) who meets Plan's participation requirements. In the

BJC shall assure that BJC and all BJC Providers comply with the terms of this
Section 5. BJC Provider shall accept as payment in full for Covered Services
rendered to Members such amounts as are paid by BJC, and BJC shall accept as

         recommendations regarding the Receiving Party's response or take other
         appropriate action regarding such Request. In acknowledgment of the
         time-sensitive nature of such 



                                       14
<PAGE>   15

         owned or controlled or under common control with BJC that does not have
         access to the Information shall be excluded from the restrictions set
         forth in the previous 2 sentences to the extent BJC takes reasonable
         steps to assure that no such individual has access to the Information
         of any other entity (whether owned or affiliated) which can reasonably
         be characterized as a competitor of Plan (which steps shall be at least
         as stringent as those taken by BJC to protect its own Information).

         (4) POST-TERMINATION INFORMATION OBLIGATIONS AND RESTRICTIONS. For a
         period of ten (10) years following the termination of this Agreement,
         the parties agree that they shall not disclose, or allow the improper
         use of, Information or the substance or terms of this Agreement to or

         Each party acknowledges the unique nature of the other party's
         Information and agrees that the other party will suffer irreparable
         harm in the event that the recipient of Information fails to comply
         with all of its obligations hereunder, and that in the event of breach
         of such obligations there would be no adequate remedy at law to fully
         compensate the non-breaching party. Accordingly, the parties hereby
         agree that the non-breaching party will be entitled to injunctive
         relief to enforce the terms hereof upon breach or anticipated breach by
         a party or by those with respect to whom that party has a duty to
         prevent disclosure or unauthorized use/misuse of Information, such
         injunctive relief to be cumulative with all other legal and equitable
         remedies available to the non-breaching party. Notwithstanding the
         foregoing, and in addition to any injunctive or other relief which may
         be available at or in equity, the parties agree that any breach of this
         Section shall entitle the non-breaching party to liquidated damages in
         the amount of One Million Dollars ($1,000,000).

services are rendered under this Agreement that, in the opinion of Plan's and
BJC's legal counsel, will substantively deprive one or both parties of the
benefit of its or their bargain under this Agreement.

If the Operating Committee is unable to resolve a Dispute within thirty (30)
days, the Operating Committee shall request the President of each party or his
or her designee to resolve the Dispute. In the event the Dispute is not resolved
within forty-five (45) days of the date one party initially sends written notice
of the Dispute to the other party, and if any party wishes to pursue the
Dispute, it shall be submitted to binding arbitration in accordance with the
rules of the National Health Lawyers Association. In no event may arbitration be
initiated more than one year following the initial sending of written notice of
the Dispute. Any arbitration proceeding under this Agreement shall be conducted
in St. Louis County, Missouri. The arbitrators shall have no authority to award
any punitive or exemplary damages, or to vary or ignore the terms of this
Agreement, and shall be bound by controlling law. If the Dispute pertains to a
matter which is generally administered by certain Plan or BJC procedures, such
as, for example, a credentialing, utilization management or quality improvement
plan, the procedures set forth in that plan must be fully exhausted before any
right to arbitration under this section may be invoked. Notwithstanding the
foregoing, neither party shall be precluded from seeking injunctive or other
relief in connection with the other party's breach or threatened breach of the
terms of Section 6, Section 7.3, Section 7.7 or Section 10.3. This section shall
survive termination of this Agreement.

9.2 RENEWAL PROCEDURE. On or before January 1, 2006, the parties shall commence
good faith negotiations regarding the terms and conditions (including without

renewal of this Agreement and the time period of any renewal (the "Renewal
Term"). The negotiation of Renewal Conditions and of the first Renewal Term
shall be completed by the parties on or before July 1, 2006.


9.3 TERMINATION. This Agreement may be terminated as follows:

         (1) NONRENEWAL. If the parties have not reached final agreement
         regarding Renewal Conditions for the first Renewal Term on or before
         July 1, 2006, this Agreement shall expire on March 31, 2007. Either
         party may elect not to renew this Agreement at the end of any Renewal
         Term(s) by giving written notice of such election at least one hundred
         eighty (180) days prior to the end of such Renewal Term(s). Thereafter,
         this Agreement shall terminate upon the last day of the Renewal Term in
         which such notice was given.


         (2) FOR CAUSE.


                  (i)  Material Breach. By either party, for the breach of a
                  material term, condition or provision of this Agreement, after
                  one hundred twenty (120) days advance written notice
                  ("Notice"), specifying such material breach, to the other
                  party provided that the breaching party shall have a minimum
                  of thirty (30) days or longer reasonable period agreed to by
                  the parties to correct or cure such material breach. If the
                  breaching party fails or refuses to cure the material breach
                  within such time, then the nonbreaching party may elect to
                  terminate this Agreement. The remedy herein provided shall not
                  be exclusive of, but shall be in addition to, any remedy
                  available at law or in equity to the nonbreaching party.

                  (ii) Failure to pay/maintain financial obligations. BJC may
                  terminate this Agreement after 30 days prior written notice to
                  Plan in the event Plan fails to deposit funds into any Claims
                  Payment Account(s) (as defined in and in accordance with the
                  Exhibits to this Agreement) provided that Plan shall have 30
                  days to correct or cure its failure to pay. GHP may terminate
                  this Agreement after 30 days prior written notice to BJC in
                  the event BJC fails to maintain the required amount of
                  continuously available funds accessible under one or more
                  Letters of Credit required by the Exhibits to this Agreement.


         (3) UPON NOTICE. BJC may terminate this Agreement upon 180 days prior
         written notice in the event GHP is acquired by a provider based
         organization (or a subsidiary or affiliate of such organization) in the
         St. Louis market that is not a BJC Provider.

         (4) PLAN REQUEST FOR TERMINATION OF BJC PROVIDERS UPON NOTICE. With
         respect to a BJC Provider's participation in the provision of Covered
         Services hereunder, in the event the Plan requires by thirty (30) days
         prior written request that BJC terminate any individual BJC Provider's
         participation. Such termination shall not result in a termination of
         this Agreement. If appropriate to support compliance with adequate



                                       17
<PAGE>   18

         access standards applicable to Plan, in the event a BJC Provider is
         terminated from participation in this Agreement upon the request of the
         Plan, BJC shall use its best efforts to replace such BJC Provider as
         soon as practicable, but in no event in excess of sixty (60) days from
         the date of such BJC Provider's termination, and in the interim, shall
         promptly make appropriate arrangements to ensure the provision of
         Covered Services to Members.

         (5) IMMEDIATE TERMINATION OF INDIVIDUAL PROVIDERS. In the event that
         one of the events listed below occurs as to a BJC Provider, Plan may
         notify BJC that such BJC Provider is no longer eligible to provide
         Covered Services to Members and BJC shall thereafter immediately cause
         such BJC Provider to cease providing Covered Services to Members:

                  (i)      The events referenced herein include:

                           A. BJC's termination or suspension of a BJC
                           Provider's membership in BJC. Any notice required by
                           this Section shall state the reason for such
                           termination, or suspension, as the case may be.

                           B. Any action involving termination of or substantial
                           limitation on a BJC Physician's or Provider's
                           hospital privileges related to quality of care or
                           ability to admit patients to any hospital or
                           inpatient facility.

                           C. Any situation that requires a BJC Provider to
                           notify a state or federal agency or licensing board
                           that results in the termination, revocation or
                           suspension of the BJC Provider's license or
                           certification.

                           D. Any situation involving an investigation conducted
                           or complaint filed by a state or federal agency or
                           licensing board that restricts a BJC Hospital's
                           ability to operate an acute care hospital, results in
                           termination or substantial limitation being placed on
                           a BJC Physician's license to practice medicine or
                           osteopathy or a BJC Ancillary Provider's license or
                           certification to provide professional services,
                           provided that Plan shall consult with BJC prior to
                           terminating a BJC Provider under this Section
                           9.3(5)(D).

                           E. A change in any BJC Provider's license to practice
                           medicine or osteopathy, any form of reportable
                           discipline against such license, a change in any BJC
                           Provider's accreditation by JCAHO, or certifications
                           including, but not limited to, those under Titles
                           XVIII or XIX of the United States Code, or a marked
                           change in any BJC Provider's license or certification
                           to provide professional services or any form of
                           reportable discipline against the same.



                                       18
<PAGE>   19

                           F. After Plan consults with BJC, in appropriate
                           circumstances Plan may require the termination of a
                           BJC Provider who or which is a defendant in a lawsuit
                           or claim filed alleging professional malpractice
                           involving a Member.


                           G. Any felony conviction of a BJC Provider.


                           H. Any BJC Provider's suspension or termination from
                           participation in Medicare or any BJC Provider's
                           suspension or involuntary termination from
                           participation in the Medical Assistance program of
                           any state.

                           I. Plan determines in good faith that the BJC
                           Provider's continued provision of services to Members
                           may result in, or is resulting in, danger to the
                           health, safety or welfare of Members.

                           J. Plan determines in good faith that, after notice
                           from Plan and opportunity to cure to BJC Provider and
                           after consultation with BJC, the BJC Provider has not
                           materially complied with the provisions of Plan's or
                           BJC's Quality Improvement or Utilization Management
                           Programs or the BJC Provider is unwilling or unable
                           to work cooperatively in a managed care environment.

                           K. One of the events of default set forth in the
                           applicable BJC Provider Agreement, occurs and
                           Plan/BJC has complied with the applicable notice
                           provisions set forth therein.

                  (ii)  Reapplication. In the event that a BJC Provider is
                  terminated hereunder, he/she may reapply to participate in the
                  Plan network in accordance with Plan's standard policies and
                  procedures. The parties understand and agree that Plan's
                  standard policies and procedures may prohibit or delay
                  reapplication in certain instances.


                  (iii) Corrective Action. If terminated for one of the items
                  set forth immediately above, a BJC Provider may utilize Plan's
                  then current applicable appeal procedure or other corrective
                  action program, if such BJC Provider would otherwise have been
                  entitled to utilize such appeal procedure or corrective action
                  program (if such program exists at the time of termination).


         (6) RIGHT TO TERMINATE AGREEMENT IMMEDIATELY. Nothing herein will be
         construed as limiting the right of either party to terminate this
         Agreement immediately upon delivery of written notice if:

                  (i)   Either party is unable to secure and/or fails to
                  maintain the necessary governmental licenses or authority
                  required for the performance of its duties under this
                  Agreement, or



                                       19
<PAGE>   20

                  (ii)  By Plan if BJC is unable to secure and/or fails to
                  maintain the required professional liability coverage required
                  under this Agreement, or (in addition to any remedies set
                  forth in the Exhibits to this Agreement) if BJC fails to
                  maintain the required Irrevocable Letter of Credit required by
                  the Exhibits to this Agreement, or

                  (iii) The Plan determines, in its reasonable discretion, that
                  the health, safety, or welfare of Members is jeopardized by
                  continuation of this Agreement, or

                  (iv)  In the event of fraud, intentional wrongdoing, or
                  misrepresentation by either party with respect to a material
                  term or obligation under this Agreement.

                  (v)   In the event either party is prohibited from
                  participation in a governmental sponsored Benefit Plan.

                  (vi)  In the event either party files a petition in voluntary
                  bankruptcy or corporate debt reorganization, makes an
                  assignment for the benefit of creditors, admits in writing to
                  its insolvency or inability to pay debts as they come due,
                  consents to or has appointed on its behalf a trustee or
                  receiver, or otherwise ceases to do business, or in the event
                  any court of competent jurisdiction assumes custody or control
                  of either parties' assets, or has an involuntary proceeding
                  commenced under bankruptcy or liquidation law which is not
                  dismissed within 60 days after the date of commencement of
                  that proceeding.

9.4 OBLIGATIONS FOLLOWING TERMINATION.

         (1) CONTINUATION OF SERVICE. If this Agreement is terminated due to the
         insolvency of the Plan, BJC shall continue to provide or arrange for
         the provision of Covered Services to Members for the period of time
         through which payment for Covered Services has been received by the
         Plan from a Payor for that Member or those Members or the period of
         time required by law, whichever is greater. BJC shall be paid for
         Covered Services rendered at the rate that is in effect between the
         parties during the period immediately preceding termination on this
         basis.


         (2) COMMUNICATION WITH MEMBERS. If this Agreement is terminated, the
         Plan may notify Members, Payors, participating employers and
         Participating and BJC Providers that BJC no longer participates with
         the Plan in the provision of Covered Services to Members. If Members
         seek services, or Participating or BJC Providers, or non-Participating
         Providers order tests or seek services from BJC or BJC Providers after
         the date of termination, BJC shall inform such Members and BJC
         Providers that BJC no longer has an agreement with Plan to arrange for
         Covered Services to Members.. BJC shall otherwise not initiate
         communications with Members, verbally or in writing, concerning the
         termination of its participation with the Plan, unless the parties have
         agreed in writing to the content of such communications. Nothing in
         this Section or in 



                                       20
<PAGE>   21


         this Agreement shall be construed to limit Physician-Patient
         communications regarding medical treatment or informed consent for
         treatment.


         (3) RESPONSIBILITY FOR MEMBERS AT TERMINATION. In the event of
         termination of this Agreement other than as provided in subsection
         9.4(1) above, BJC and BJC Providers shall continue to provide Covered
         Services to Members in accordance with this Agreement for one year from
         the effective date of termination. Any such Covered Services rendered
         by BJC or BJC Providers to Members on a post-termination basis pursuant
         to this Section shall be reimbursed by the Plan or the appropriate
         Payor at the rate at which BJC and BJC providers are compensated during
         the period immediately preceding such termination.

         (4) TERMINATION OF PROVIDER UPON NOTICE. In the event a BJC Provider is
         terminated from participation in this Agreement upon notice, such
         termination will occur on the last day of the month in which the
         ninetieth (90th) day following the requisite notice occurs. In the
         event of such termination, and upon Plan's reasonable request taking
         into account the access and service needs of Members, BJC shall replace
         the terminated BJC Provider with a BJC Provider that meets the
         credentialing criteria specified in this Agreement and all of the
         Plan's Medical Management Program and Credentialing Plan requirements
         as soon as reasonably possible. While BJC is in the process of securing
         said replacement BJC Provider, BJC shall promptly make all necessary
         and appropriate arrangements to ensure that the access and service
         needs of Member receiving Covered Services under this Agreement are
         fulfilled.

         (5) PARTICIPATION AGREEMENTS. Upon termination of this Agreement, Plan
         shall have the right to contract directly with any BJC Provider upon
         terms to be agreed upon between Plan and such BJC Provider. BJC agrees
         that it shall not in any way interfere with Plan's contracting efforts.
         BJC further agrees that it shall include in any BJC Provider Agreement
         or impose as a condition of continued affiliation with BJC a clause,
         policy or provision prohibiting such BJC Provider from directly
         contracting with GHP upon termination of this Agreement.

         (6) INFORMATION SYSTEMS. Plan shall continue to provide BJC and BJC
         Providers with applicable information support services as required by
         this Agreement during the continuation period described in this Section
         9.4.

         (7) ACCESS TO RECORDS. Consistent with the terms of Section 7.8(4)
         above, upon termination of this Agreement and for a period of 10 years
         from the date of termination, each party shall provide the other party
         with full access to (including the right to make copies of and/or use
         computer-readable and hard copies of) all data and information of the
         requesting party developed during the term of this Agreement relating
         to (i) the performance by BJC Providers under the Credentialing, UM/QA
         and related programs, and (ii) claims utilization case management
         payment and outcome data with respect to each Member provided any
         Covered Services during the term of this Agreement. During the
         Continuation Period and thereafter, each party agrees that it shall not
         in any manner




                                       21
<PAGE>   22

         disparage the other party (or any BJC or Participating Provider) or any
         products or services of such other party (or any BJC or Participating
         Provider).

                                   SECTION 10
                                  MISCELLANEOUS


10.1 NO SOLICITATION OF MEMBERS. The parties agree that during (1) the initial
term of this Agreement, plus (2) any Renewal Term(s) of this Agreement, plus (3)
the expiration of the continuation period set forth in Section 9.4(3) above, BJC
and BJC Providers shall not, directly or through employed or contracted brokers,
agents or producers, solicit, encourage, suggest, or otherwise communicate with
("Solicit") Members, or attempt to Solicit Members regarding changing such
Members' health care coverage from Plan to another insurer, managed care, health
care financing, TPA or similar entity or organization, ("Competitor") regardless
of whether such Competitor is related to, under contract with, or otherwise
affiliated with BJC. This Section shall survive termination of this Agreement.
Nothing in this Section shall be construed to limit the physician/patient
relationship or interfere with physician/patient communications regarding a
patient's medical condition or informed consent to treatment.

attempt to Solicit any person who was employed by the other party hereto on a
full or part-time basis while this Agreement was in effect to leave the employ
of the other party hereto without the prior written consent of the other party.
For purposes of this Agreement, indirect Solicitation shall not include
advertising in professional journals and newspapers, provided the party so
advertising does not request or advise such employee to submit an application
for such advertised positions. This Section shall survive termination of this
Agreement.


10.3 AMENDMENT. This Agreement may be amended only in writing, and the amendment
must be executed by both parties. Modification by Plan of its Provider Manual,
Credentialing Plan, Utilization Management Plan, Administrative Manual,
Underwriting Guidelines, Sales and Marketing Plan, or other such internal
documents, policies and procedures, shall not constitute an Amendment to this
Agreement unless such modification materially conflicts with the provisions of
this Agreement or materially increases BJC's responsibilities or financial
obligations under this Agreement.

10.4 REGULATORY AMENDMENT. Plan also may amend this Agreement after discussion
with BJC to comply with applicable statutes and regulations, standards and
guidelines, and shall give notice to BJC of such amendment and its effective
date. Such amendment will not require agreement by BJC.

under this Agreement, including without limitation any and all financial
obligations and the financial stability of such proposed assignee.

guarantee acceptable to Plan of all representations, warranties, and obligations
(including without limitation financial obligations) under this Agreement in
connection with an assignment to an entity controlling, controlled by, or under

complete such an assignment unless the Plan reasonably determines that the
proposed assignee is a competitor of Plan. The form of such Corporate Guarantee
is attached hereto as EXHIBIT J. The parties agree that in the event Plan
believes the proposed assignee is a competitor of Plan, Plan shall so notify BJC
within the 30 day notice period referenced herein. If BJC does not agree with
Plan's designation of the proposed assignee as a competitor, the parties shall
submit the issue to the dispute resolution process set forth in Section 8 this
Agreement. Neither party may assign any of its rights and responsibilities under
this Agreement to any other person or entity without the prior written consent

obligations under this Agreement, including without limitation any and all
financial obligations and the financial stability of such proposed assignee.

                                   EXHIBIT A-1
                           GLOBAL CAPITATION PAYMENTS

                             SECTION 1: DEFINITIONS

COPAYMENT: The amount a Member is required to pay and BJC Provider shall collect
for certain Covered Services in accordance with the Member's Benefit Plan.

CUSTOMARY CHARGE: The reasonable and customary fees charged by a provider,
Participating Provider or BJC Provider ("billed charges") which do not exceed
the billed charges such provider would charge any other person regardless of
whether the person is a Member.

DEDUCTIBLE: The annual amount of charges for Covered Services, as provided in
the Member's Benefit Plan, which the Member is required to pay and which, to the
extent applicable to Covered Services provided by BJC Provider, BJC Provider may
collect in accordance with the Member's Benefit Plan.


BJC MEMBER: A Member who has selected or has been assigned to a BJC Provider
(including without limitation a BJC Provider located in or associated with a
Medical Center) as his or her PCP.

BJC PREMIUM:  The amount of compensation to be paid to BJC for the services to
be provided by or through BJC and BJC Providers, including without limitation,
Covered Services rendered to BJC Members.  BJC Premium shall be stated in this
Exhibit as a percentage of Total Premium per BJC Member per month (see section
3.1 below).  BJC Providers shall collect from Members and may retain collected
Copayments, Deductibles or charges for services which are not Covered Services
(whether by reason of an exclusion, exhaustion of benefits, benefit maximums,
and recoveries from coordination of benefits, third party claims and subrogation
to the extent permitted by law, and similar bases, but not amounts not paid by
reason of a UM determination) under a Member's Benefit Plan.  Such collected
amounts shall be in addition to and shall not be deemed part of the BJC Premium.

TOTAL PREMIUM:  The gross amount of premium actually collected by Plan for each
BJC Member per month including the premium actually collected by Plan for each
BJC Member for the issuance of a Rider attached to or made part of the BJC
Member's Benefit Plan.  The parties acknowledge that due to systems issues, as
of the Effective Date of this Agreement for purposes of calculating the amount
of monthly deposits into the Claims Payment Account, (1) for the first month
under this Exhibit A-1, GHP is depositing an amount determined as the average
gross premium per Member per month multiplied by the total number of Members who
selected a Medical Center physician as such Member's PCP for the immediately
preceding month (i.e., pre-execution/Effective Date); (2) for the second and
subsequent months under this Exhibit A-1, GHP is depositing an amount determined
as the average gross premium per BJC Member per month multiplied by the total
number of BJC Members for the immediately preceding month plus or minus the
adjustment for the amount determined as the amount of gross premium billed plus
retroactive accretions and minus retroactive deletions, if any, (to the extent
permitted in accordance with Section 3.5 of this Exhibit A-1) billed by Plan for
each BJC Member per month for the immediately preceding month.

TOTAL PROVIDER PAYMENTS:  The total amount of payments made by Plan to any
providers, including BJC Providers, for the provision of Covered Services to BJC
Members incurred during the applicable period (e.g., calendar year).


                                       26

*CONFIDENTIAL INFORMATION HAS BEEN OMITTED AND FILED SEPARATELY WITH THE
COMMISSION.

TOTAL PROVIDER PAYMENTS: The total amount of payments made by Plan to any
providers, including BJC Providers, for the provision of Covered Services to BJC
Members incurred during the applicable period (e.g., calendar year).

                           SECTION 2: SCOPE OF EXHIBIT


The provisions of this Exhibit apply to Covered Services rendered to BJC Members
who are covered by all commercial insured products (Benefit Plans) sponsored or
issued by all Payors, regardless of whether such BJC Members receive Covered
Services from BJC Providers, Participating Providers or non-Participating
Providers within or outside of BJC's Service Sites or within or outside of
Plan's Service Area.


                          SECTION 3: PAYMENT OBLIGATION


3.1 PAYMENT FOR SERVICES.  In consideration of BJC's arranging for the provision
of all Covered Services to BJC Members covered by Benefit Plans within the
scope of this Exhibit, of BJC's assumption of the financial risk associated
with the provision of such Covered Services to BJC Members, and of BJC's
performance of its obligations under this Agreement, Plan shall pay BJC in
accordance with the payment and claims processing procedures set forth in this
Exhibit A-1.  The amount of payment shall be the BJC Premium set forth below:

Calendar Year:                     BJC Premium:
1997                                  [_]*
1998                                  [_]*  
1999                                  [_]*  
2000-2002                             [_]*
2003-2007                             [_]*  

In no event shall such percentage be deemed to include the amount or value of
any Copayaments or Deductibles, or recoveries from appropriate coordination of
benefits, third party claims or subrogation recoveries to the extent permitted
by law which BJC Providers may be entitled to collect for certain Covered
Services as set forth in BJC Member's Benefit Plans.
                                                                 
                                                                 
                                                                 
                                                                 


3.2 INCENTIVE AND MINIMUM PREMIUM FLOOR. [SEE SCHEDULE A-1]

3.3 PAYMENT PROCESS FOR BJC MEMBERS. The parties agree that the following
process shall be used to assure the timely payment of claims for BJC Members
covered by Benefit Plans within the scope of this Exhibit:

         (1) Establishment of Claims Payment Account. The parties shall mutually
         agree upon the bank and type of account into which GHP shall deposit
         BJC Premium and out of 



                                       27
<PAGE>   28

         which GHP shall process claims for Covered Services for BJC Members
         (the "Claims Payment Account"). The parties acknowledge that the Claims
         Payment Account may contain BJC Premium and BJC Medicare Premium (as
         that term is defined in Exhibit A-3) but not BJC Medicaid Premium (as
         that term is defined in Exhibit A-2). BJC shall complete such forms as
         may be required by the Bank to grant GHP the right to access funds
         necessary to pay claims from the Claims Payment Account. BJC and GHP
         shall jointly complete any forms necessary to allow BJC and GHP access
         to Claims Payment Account information (including without limitation
         monthly balance statements). The parties acknowledge that the Claims
         Payment Account shall remain the property of BJC and that any interest,
         earnings or other income derived or accrued on the investment of such
         account funds shall also be the property of BJC; provided, however,
         that BJC understands and agrees that under no circumstances may BJC
         directly withdraw funds from the Claims Payment Account without the
         prior written consent of Plan, which consent shall not be unreasonably
         withheld. Plan may withdraw from the Claims Payment Account amounts due
         to health care providers for the provision of Covered Services to BJC
         Members, including without limitation, amounts due to BJC Providers,
         Participating Providers and non-Participating providers under
         applicable fee schedules, Customary Charges and other fees-for-services
         and applicable capitation payments (such amounts are hereafter
         collectively referred to as "Claims") in accordance with the Claims
         payment procedures set forth in this Section 3.3. Plan shall not
         withdraw or access funds or any moneys from the Claims Payment Account
         or the BJC ILOC other than for the purposes described in this Section
         3. Plan shall provide BJC reports regarding Claims as required
         elsewhere in this Agreement.

         (2) Calculation of Claims Payment Account. On the fifteenth (15th) day
         of each calendar month or the next business day in the event the
         fifteenth (15th) day of the month is a Saturday, Sunday or bank
         holiday, GHP shall, after calculating Total Premiums and BJC Premium
         for the purpose of determining the deposit amount for each BJC Member
         per month, calculate and deposit into the Claims Payment Account an
         amount equal to the applicable BJC Premium that Plan collected from or
         on behalf of BJC Members.

         (3) Letter of Credit. BJC shall at all times maintain an Irrevocable
         Letter of Credit (the "BJC ILOC") (the form of which shall be attached
         hereto as EXHIBIT L attached to the Claims Payment Account which may be
         drawn upon directly by GHP in the event the Claims Payment Account does
         not have sufficient funds to pay for claims for Covered Services
         rendered to BJC Members. The BJC ILOC shall be continuously maintained
         in an amount equal to three months of claims for BJC Members averaged
         over the immediately preceding 6 months. BJC shall assure at any time
         and at all times during the any term of this Agreement and any
         extensions thereof, that (1) GHP at any time and from time to time may
         directly access the BJC ILOC, (2) GHP at any time and at all times has
         access to information on the BJC ILOC and (3) the BJC ILOC maintains a
         continuous minimum available and accessible amount equal to 3 months of
         claims for BJC Members averaged over the immediately preceding 6
         months.

         (4)      Claims Payment Procedures and Access to BJC ILOC.

                  (i)  Non-Capitation Payment Procedures. On a weekly basis, GHP
                  shall perform a check run and determine the amount necessary
                  to cover non-capitation Claims adjudicated for BJC Members
                  during the immediately preceding week. GHP shall determine by
                  confirming with the bank that the Claims Payment Account
                  contains sufficient funds to cover the total amount of that
                  non-capitation Claims check run and, upon receiving such
                  confirmation, GHP shall release all checks for such Claims
                  adjudicated for BJC Members during the immediately preceding
                  week. In the event GHP receives information from the bank that
                  the Claims Payment Account does not have sufficient funds to
                  cover such non-capitation Claims check run, GHP shall notify
                  the BJC Contact Person identified pursuant to Section 3 of
                  this Agreement of the amount of the shortfall. BJC shall then
                  have one business day to transfer the necessary amount via ACH
                  transfer from an alternative BJC account into the Claims
                  Payment Account. In the event BJC does not complete the ACH
                  transfer, GHP may without further notice to BJC access the BJC
                  ILOC in the amount necessary to cover the total amount of that
                  non-capitation Claims check run and release the checks to
                  cover the total amount of that check run. Within 2 business
                  days of GHP's completion of accessing the BJC ILOC, BJC shall
                  complete any and all steps necessary to maintain the
                  continuous minimum BJC ILOC amount available to and accessible
                  by GHP as required by subsection (3) above.

                  (ii) Capitation Payment Procedures. On a monthly basis, GHP
                  shall perform a check run and determine the amount necessary
                  to cover Capitation payments applicable to BJC Members during
                  the current month. GHP shall determine by confirming with the
                  bank that the Claims Payment Account contains sufficient funds
                  to cover the total amount of the Capitation check run and,
                  upon receiving such confirmation, GHP shall initiate an ACH
                  transfer of sufficient funds from the Claims Payment Account
                  into an account to be designated by GHP and, upon receiving
                  confirmation of the ACH transfer, GHP shall release all checks
                  for that Capitation check run. In the event GHP receives
                  information from the bank that the Claims Payment Account does
                  not have sufficient funds to cover that Capitation check run,
                  GHP shall notify the BJC Contact Person identified pursuant to
                  Section 3 of the Agreement of the amount of the shortfall. BJC
                  shall then have one business day to transfer the necessary
                  amount via ACH transfer from an alternative BJC account into
                  the Claims Payment Account. In the event BJC does not complete
                  the ACH transfer, GHP may without further notice to BJC
                  directly access the BJC ILOC in the amount necessary to cover
                  the total amount of that Capitation check run and release the
                  checks to cover the total amount of that Capitation check run.
                  Within 2 business days of GHP's completion of accessing the
                  BJC ILOC, BJC shall complete any and all steps necessary to
                  maintain the continuous minimum BJC ILOC amount available to
                  and accessible by GHP as required by subsection (3) above.

         (5) Provider Submission of and Adjustments to Claims for Covered
         Services. BJC shall assure that BJC Providers submit claims for BJC
         Member Covered Services to Plan in a manner and format prescribed by
         Plan. At Plan's request, BJC Provider may be required to submit such
         claims electronically in a manner and form agreed to by the parties and
         on at least 60 days notice to the BJC Provider. BJC Member Covered
         Services claims must be received by Plan no more than 60 days from the
         date the Covered Services were rendered. Provider agrees that claims
         received from and after 90 days from the date BJC Member Covered
         Services were rendered may be rejected for payment, at Plan's
         discretion; provided, however, that corrections or additions to such
         claims shall be considered by Plan if made within 30 days from BJC
         Provider's receipt of the initial claim payment.


         Unless otherwise directed by Plan, BJC shall assure that BJC Providers
         submit claims using current HCFA 1500 or UB92 forms with current HCPCS
         coding, if applicable, current ICD9 coding and current CPT coding. BJC
         Providers shall include in a claim the BJC Member number and BJC
         Provider's Customary Charge for the Covered Services rendered to a BJC
         Member during a single instance of service. If requested by Plan, BJC
         Provider shall also submit BJC Provider's Federal Tax I.D. number
         and/or other identifiers.

         Plan shall have the right to make corrective adjustments to any
         previous BJC Provider payment for a claim for Covered Services;
         provided, however, that any corrections shall be made either (1) within
         6 months from receipt by Plan of such claim; (2) as part of an annual
         reconciliation procedure; or (3) at any time as part of a Plan audit of
         BJC's or BJC Provider's claims to the extent such claims adjustments
         arise out of billing errors, or improper, fraudulent or abusive billing
         practices.


         (6) Claims Responsibility. The parties understand and agree that under
         state and/or federal statutes and regulations governing insurers, HMOs
         and claims turnaround times/payment procedures, Plan may be required to
         pay any due and outstanding Claims even in the event that amounts then
         in the Claims Payment Account are unavailable to Plan and/or
         insufficient to pay such Claims, putting Plan at risk for Claims
         responsibility contrary to the intent of this Agreement. In the event
         Plan is required to make Claims payments under the circumstances
         described in this subsection 6, BJC agrees that to the extent the funds
         necessary to pay the Claims were not directly and timely available to
         GHP under the BJC ILOC, then , BJC shall hold harmless and indemnify
         Plan for any and all payments, losses, claims, liabilities, actions,
         suits, causes of action, administrative or regulatory proceedings,
         costs and expenses arising out of or related to such Claims payments.
         In addition, BJC shall assure that BJC Providers do not bill any Member
         for Covered Services if BJC Provider fails to submit claims in
         accordance with the terms and conditions set forth in this Agreement
         (including without limitation this and any other applicable Exhibits,
         appendices, addendums or attachments), and BJC shall indemnify and hold
         harmless Plan and BJC Member for all payments, losses, liabilities,
         claims, suits, actions, causes of action, costs and expenses incurred
         by Plan and BJC Member arising out of BJC Providers' failure to comply
         with the prohibition on billing contained 



                                       30
<PAGE>   31

         in this Agreement, including without limitation this and any other
         Exhibits, appendices or attachments.


3.4 ELIGIBILITY AND BENEFIT VERIFICATION. Plan shall be responsible for the
determination under each Benefit Plan covered under the scope of this Exhibit as
to whether (i) a person receiving services, supplies, products or accommodations
from a BJC Provider is a BJC Member, and (ii) the services, supplies, products
and accommodation provided to a BJC Member are Covered Services. Plan shall
provide BJC with the claims, eligibility and other reports identified in EXHIBIT
E and Plan shall use its reasonable efforts to provide BJC and BJC Providers in
the future with real time access to Plan's eligibility files to verify BJC
Member eligibility and coverage. Plan agrees that eligibility verification
processes shall be reasonable and consistently and uniformly applied to each BJC
Provider. Plan shall make eligibility determinations according to its then
current policies.


3.5 ADJUSTMENTS FOR RETROACTIVE ELIGIBILITY AND BENEFIT DETERMINATIONS: The
parties acknowledge that Plan may from time to time make retroactive adjustments
to eligibility and benefit determinations. Plan agrees to use reasonable efforts
to keep such retroactive determinations to a minimum, and to enforce Benefit
Plan provisions prohibiting such practices by employers to the extent reasonably
possible using sound business judgment considering the particular employer group
and Benefit Plan.


         (1) Retroactive Eligibility Cancellations. If a BJC Member's
         eligibility has been canceled retroactively, Plan may deduct from
         deposits to be made into the Claims Payment Account an amount equal to
         the BJC Premium previously deposited into the Claims Payment Account on
         account of such BJC Member after the date of the retroactive
         cancellation: provided, however, such amount shall not exceed an amount
         equal to 6 months of BJC Premium for such BJC Member. BJC shall assure
         that Plan may recoup from a BJC Provider any claims payments made to
         BJC Providers on behalf of such BJC Member during such time as the BJC
         Member was not eligible. BJC and BJC Providers may then bill such BJC
         Member for services rendered during such period of ineligibility, which
         billing shall not constitute a violation of the member protection and
         no balance billing provisions set forth in this Agreement.

         (2) Retroactive Eligibility Additions. If a BJC Member's enrollment in
         a BJC Provider's practice has been added retroactively, Plan shall make
         a deposit into the Claims Payment Account in an amount equal to the BJC
         Premium received (and Plan shall deduct from the Claims Payment Account
         an amount equal to the claims for Covered Services paid on behalf of
         such BJC Member) during the time period such BJC Member was eligible
         but not treated as a BJC Member for claims payment purposes. Such
         retroactive adjustments shall be made for a period not to exceed 6
         months. BJC shall assure that Plan may offset and/or recoup from a BJC
         Provider any claims payments made to BJC Providers under another
         agreement or another Exhibit to this Agreement during such time as the
         BJC Member was eligible but not treated as a BJC Member for claims
         payment purposes.




                                       31
<PAGE>   32

The financial terms and conditions set forth in this Section 3.5 shall be BJC
Provider's sole and exclusive remedy for failing to notify Plan of a BJC
Member's enrollment in BJC Provider's practice.

                      SECTION 4: RECONCILIATION PROCEDURES


4.1 ACKNOWLEDGMENT. The parties understand and agree that because the BJC
Premium and resulting amount paid into the Claims Payment Account differs for
each Benefit Plan and BJC Member, and because the payment procedures differ for
BJC Members and for BJC Medicaid Members, the calculations and reconciliations
under this Section 4 shall not be aggregated and shall be made separately for
the Medicaid Benefit Plan, and other Benefit Plans included under Section 2 of
this Exhibit.

4.2 BJC QUARTERLY WITHDRAWALS FROM CLAIMS PAYMENT ACCOUNT. The parties agree
that from and after the fifteenth month of this Agreement, BJC may request
quarterly withdrawals from the Claims Payment Account. GHP shall grant BJC's
request if the Claims Payment Account has sustained a continuous minimum balance
of at least 110% of the average monthly claims payment averaged over the
immediately preceding 12 month period experience.


4.3 ANNUAL PREMIUM RECONCILIATION. Within 180 days after the end of each
calendar year (the "Annual Premium Reconciliation Period") identified in Section
3.1 of this Exhibit, Plan shall calculate the difference between (i) the BJC
Premium Amount for the Annual Premium Reconciliation Period less any BJC
Quarterly Withdrawals actually paid to BJC plus any amounts that were funded
directly by BJC upon request of Plan or drawn upon or accessed via the BJC ILOC
for the same period and (ii) the amount of Total Provider Payments made by Plan
for Covered Services provided to BJC Members during such calendar year plus IBNR
claims less any amounts actually recovered by Plan from an applicable reinsurer
(the "Premium Reconciliation Amount"). In the event that the Premium
Reconciliation Amount is a positive number Plan shall pay that amount to BJC
within 15 days of the completion of the Annual Premium Reconciliation. In the
event the Premium Reconciliation Amount is a negative number BJC shall pay that
amount to Plan within 15 days after receipt from Plan of the results of the
Annual Premium Reconciliation. Any claims for Covered Services provided to BJC
Members which have been presented for payment or which have otherwise been
identified but have not been paid within 150 days after the end of such calendar
year shall be appropriately accrued for and included in the Annual Premium
Reconciliation. Any such claims presented to Plan for payment following
completion of the Annual Premium Reconciliation for a given calendar year shall
be forwarded to BJC and payment of such claims shall be entirely BJC's
responsibility. To the extent that Plan is required to pay any such claims it
may offset such payments against BJC Premium amounts due to BJC in the future.
Any premium payments received by Plan for a given calendar year from which BJC
Premiums are required to be calculated and which are received after the
completion of the Annual Premium Reconciliation for that calendar year shall be
forwarded to BJC.






                                       32
<PAGE>   33




4.4 FINAL PREMIUM RECONCILIATION. In the event of termination of this Agreement
Plan shall within 180 days of the effective date of termination calculate for
any periods for which Premium Reconciliation Amounts have not already been
calculated and paid (the "Final Reconciliation Period") the difference between:
(i) the BJC Premium Amount for such Final Reconciliation Period less any BJC
Quarterly Withdrawals actually paid to BJC during the Final Reconciliation
Period, plus any amounts that were actually funded directly by BJC upon request
of Plan or drawn upon or accessed via the BJC ILOC for the same period and (ii)
the amount of Total Provider Payments made by Plan for Covered Services provided
to BJC Members during the Final Reconciliation Period plus claims for such Final
Reconciliation Period less any amounts recovered by Plan from an applicable
reinsurer not already calculated (the "Final Premium Reconciliation Amount")
calculated consistently with Plan's other IBNR claims calculations. Any Final
Premium Reconciliation Amounts owed by either party shall be paid within 90 days
of receipt of notice of the Final Premium Reconciliation Amount. Any Premium
Reconciliation Amounts previously calculated as due from one party to the other,
but not yet paid shall be paid at the same time.

4.5 SUPPORTING INFORMATION; PREMIUM RECONCILIATION AUDIT RIGHTS. Within 180 days
after the end of each calendar year and within 180 days of the effective date of
termination of this Agreement Plan shall provide to BJC information
establishing: (i) the Total Premium in respect of such calendar year; (ii) the
Total Provider Payments in respect of such calendar year; and (iii) Plan's
calculation of the BJC Premium amount and the Premium Reconciliation for such
calendar year. BJC shall be entitled to review and to conduct an audit (either
by BJC or by independent auditors acceptable to Plan) of Plan's books and
records to verify such amounts and calculations as claimed by Plan. Any such
review and/or audit shall be conducted at BJC's expense. If as the result of any
such review or audit it is determined that the Premium Reconciliation as
conducted by Plan was incorrect, Plan shall promptly correct the Premium
Reconciliation. In the event BJC and Plan are unable after good faith efforts
for at least 60 days to resolve a dispute with regard to any such amount or
calculation such dispute shall be settled in accordance with the dispute
resolution provisions of this Agreement.

4.6 ANNUAL CLAIMS AUDIT RIGHTS. From and after October 1, 1997, BJC shall have
the right to conduct quarterly audits of Plan's performance of the claims
processing and claims payment function under this Agreement, but not more
frequently than two times per year. Such an annual audit shall be conducted at
BJC's sole expense, shall be completed within 180 days of the end of each year
for the immediately preceding year, and shall be performed by a nationally
recognized third party reasonably acceptable to Plan in view of Plan's
reasonable competitive concerns. Such third party shall have access to and be
entitled to review Plan's applicable Participating Provider agreement fee
information, if any, and other books and records necessary to verify whether
claims were correctly paid by Plan. Plan shall be given the opportunity to
comment on the auditor's report prior to release, and all such comments shall be
disclosed to BJC. The auditor's report to BJC shall specifically not include any
blanket references to or specific or general disclosures of Plan's fee schedules
or other rate or payment arrangements with non BJC Providers, but shall instead
confirm to BJC whether Plan correctly paid the amount of the claim in accordance
with the bill or the Plan Participation Agreement in effect with such claimant,
as applicable. In the event the auditor's report to BJC states that Plan has not
paid specific claims 



                                       33
<PAGE>   34


correctly, Plan shall use the same efforts it uses in the ordinary course of
business with respect to non-BJC claims to recover the amount incorrectly paid.
Any amounts recovered by Plan shall be deposited into the Claims Payment
Account.

*CONFIDENTIAL INFORMATION HAS BEEN OMITTED AND FILED SEPARATELY WITH THE
COMMISSION.


                                  SCHEDULE A-1
                    INCENTIVE AND MINIMUM PREMIUM ADJUSTMENTS


It is the intent of the parties to incent BJC, BJC Providers and GHP to grow the
size and enrollment of BJC Members in Benefit Plans covered by Exhibit A-1,
while maintaining high patient and member satisfaction and appropriate Benefit
Plan pricing in comparison to GHP's St. Louis market competitors' pricing
practices for substantially similar employer groups and Benefit Plans, adjusted
by age/sex/industry/benefit package.

To that end and purpose the parties agree that on an annual basis beginning in
year two of this Agreement (April 1, 1998) an adjustment to the BJC Premium
will be calculated and considered for the immediately following year.  The
parties agree that during the first year of this Agrement (April 1, 1997 through
March 31, 1998) no incentive and minimum premium adjustment will be effective,
it being the parties intent that incentive and minimum premium adjustments will 
first be implemented in the second year of this Agreement (April 1, 1998 through
March 31, 1999).

The maximum incentive and minimum premium adjustment on a non-cumulative,
reset, annual basis shall be 200 basis points either above or below the BJC
Premium percentage as shown in Section 3.1 of Exhibit A-1 except as noted below
for membership carryover based on the outcome of the analysis and consideration
of the factors and adjustment formula set forth in this Schedule A-1.

The following factors will be collectively considered for this purpose.

     1)   Membership growth factor , unless patient satisfaction is negatively
          impacted as described below;
     2)   Premium Floor Analysis - factors calculated on an annual basis as
          described below.

MEMBERSHIP GROWTH threshold of [__]* in year over year comparison shall be
considered for payment as follows on a prospective (immediately following one
year period only) basis as an increase adjustment to the BJC Premium percentage
delineated in Section 3.1 of Exhibit A-1 for the then current year:

          [__]*

The above potential increases shall be limited based on the consideration of
any statistically significant decline in the patient satisfaction of BJC
Membership as monitored by BJC's and/or GHP's quarterly customer service
surveys to be agreed upon by the parties.



                                       35
<PAGE>   36

Such adjustment, if any, for membership growth will continue carryover for an
additional year after initial calculation at 50% of the original amount.

MINIMUM PREMIUM FLOOR calculation shall be based on an annual analysis of the
annual changes by GHP's St. Louis market competitors' pricing practices for
substantially similar employer groups and Benefit Plans, adjusted by
age/sex/industry/benefit package during the immediately preceding year.  
A nationally recognized actuarial firm, acceptable to both parties, will be 
retained at BJC's sole expense to develop the analysis which will serve as the 
basis for the mutually agreeable figure representing the annual market premium
change for the St. Louis market based on Benefit Plan equivalent products
(commercial HMO products) in force during the immediately preceding year by
GHP's St. Louis market competitors to similar employer groups, such Benefit
Plans to be appropriately adjusted for age/sex/industry/benefit package.

The agreed upon figure representing the St. Louis market premium change during 
the immediately preceding year as described above will be compared to the
premium change in the BJC Membership commercial book of GHP business (BJC Book) 
calculated as follows:

Comparing the change in premium from the average collected premium per BJC
Member per month in the BJC Book for comparable benefits from the month of April
in the immediately preceding year to the same average per BJC Member per month
premium collected for April of the then current year (i.e., from April to
April), age/sex/industry factor/and benefit adjusted.

If the market premium change is within 250 basis points of the change in the
BJC book premium change then this analysis and calculation will have no impact
on the incentive/floor adjustment and will not result in the adjustment of BJC
Premium for the immediately following year.

If the St. Louis market premium change is greater than 250 basis points as
compared to the BJC Book premium change, then the amount of the excess
multiplied by 50% increases only the immediately following one year BJC premium
percentage. If the St. Louis market premium change is more than 250 basis less
as compared to the BJC Book premium change, then the amount of the excess
multiplied by 50% decreases only the immediately following one year BJC Premium
percentage.

These calculations are non-cumulative and will be reset on an annual basis
beginning in year 2 of the Agreement.

This analysis and comparison of premium change in the St. Louis market and BJC
Book and membership growth will be exclusive of any accounts/employer groups
that have had premium pricing specifically discussed and mutually agreed upon
between the parties, and shall exclude the Gateway Purchasing Alliance for the
1998 calculation.

The total incentive and minimum premium adjustment for the immediately
following year shall be the sum of the amount calculated for membership growth
and the amount calculated for minimum premium floor, the total of which shall
not exceed 200 basis points either higher or lower than the percentage shown in
Section 3.1 of Exhibit A-1. With the exception that 200



                                   



                                       36


<PAGE>   37
basis points may be exceeded if such additional amount over 200 basis points is
the result of second year carryover 50% of membership growth adjustment.

                        PAYMENT FOR BJC MEDICAID MEMBERS


                             SECTION 1: DEFINITIONS

COPAYMENT: The amount a Member is required to pay, if any, and BJC Provider
shall collect for certain Covered Services in accordance with the Member's
Benefit Plan.

COVERED SERVICES: All health care services and supplies covered by or on behalf
of a BJC Medicaid Member except for transportation services as defined in the
Medicaid Benefit Plan which shall be retained by HealthCare USA of Missouri, LLC
("HCUSA").

CUSTOMARY CHARGE: The reasonable and customary fees charged by a provider,
Participating Provider or BJC Provider ("billed charges") which do not exceed
the then-current Medicaid Fee Schedule.

DEDUCTIBLE: The annual amount of charges for Covered Services, if any is
provided in the Member's Benefit Plan, which the Member is required to pay and
which, to the extent applicable to the Covered Services provided by BJC
Provider, BJC Provider may collect in accordance with the Member's Benefit Plan.

BJC MEMBER: A Member who has selected or has been assigned to a BJC Provider
(including without limitation a BJC Provider located in or associated with a
Medical Center) as his or her PCP.

BJC MEDICAID MEMBER: A BJC Member covered by the Missouri MC Plus program and
enrolled in HCUSA. The parties acknowledge that not all BJC Providers may
participate in the Medicaid program or agree to provide Covered Services for BJC
Medicaid Members under the terms of this Exhibit A-2.

BJC PREMIUM: The amount of compensation to be paid to BJC for the services to be
provided by or through BJC and BJC Providers, including Covered Services
rendered to BJC Medicaid Members. BJC Premium shall be stated in this Exhibit as
a percentage of Total Premium per BJC Medicaid Member per month (see section 3.1
below), which percentage shall be reduced by $.81 per BJC Medicaid Member per
month, to reflect HCUSA's retention of responsibility for transportation
services from Covered Services as defined herein. BJC Providers shall collect
from BJC Medicaid Members and may retain collected Copayments. Deductibles or
charges for services which are not Covered Services (whether by reason of an
exclusion, exhaustion of benefits, benefits maximums, and recoveries from
coordination of benefits, third party claims and subrogation to the extent
permitted by law, and similar bases, but not amounts not paid by reason of a UM
determination) under a BJC Medicaid Member's Benefit Plan. Such collected
amounts shall be in addition to and shall not be deemed part of the BJC Premium.

TOTAL PREMIUM: The amount of premium actually collected by Plan from the State
of Missouri for each BJC Medicaid Member per month and such other payments
actually collected by Plan from the State of Missouri for each BJC Medicaid
Member (i.e., Kick payments) to the extent the parties agree such payments are
permitted by law. The parties acknowledge that due to systems issues, as of the
Effective Day of this Agreement, for purposes of calculating the amount of
monthly deposits into the Claims Payment Account, HCUSA is depositing an amount
determined as the amount of premium received plus retroactive accretions and
minus retroactive deletions Plan for each BJC Medicaid Member per month.

                           SECTION 2: SCOPE OF EXHIBIT

The provisions of this Exhibit apply to Covered Services rendered to BJC
Medicaid Members, regardless of whether such BJC Medicaid Members receive
Covered Services from BJC Providers, Participating Providers or
non-Participating Providers within or outside of BJC's Service Sites or within
or outside of Plan's Service Area.

                          SECTION 3: PAYMENT OBLIGATION
                                     [_]*


3.1 PAYMENT FOR SERVICES. In consideration of BJC's arranging for the provision
of all Covered Services to BJC Medicaid Members, of BJC's assumption of the
financial risk associated with the provision of such Covered Services to BJC
Medicaid Members, and of BJC's performance of its obligations under this
Agreement, Plan shall pay BJC in accordance with the payment and claims
processing procedures set forth in this Exhibit A-2. The amount of payment
shall be the BJC Premium set forth below:

<TABLE>
<CAPTION>
Calendar Year:                  BJC Premium:
- --------------                  ------------
<S>                             <C>
1997                               [___]*

2003-2007                          [___]*
</TABLE>

As provided in Section 1 above, in no event shall such percentage be deemed to
include the amount or value of any copayments which BJC Providers may be
entitled to collect for certain Covered Services as set forth in BJC Medicaid
Members' Benefit Plans and as permitted by law.

3.2 PAYMENT PROCESS FOR BJC MEDICAID MEMBERS. The parties agree that the
following process shall be used to assure the timely payment of claims for BJC
Medicaid Members covered by Benefit Plans within the scope of this Exhibit:



                                       39
<PAGE>   40

         (1) Establishment of Claims Payment Account. The parties shall mutually
         agree upon the bank and type of segregated account into which HCUSA
         shall deposit only BJC Premium and out of which HCUSA shall process
         claims only for Covered Services for BJC Medicaid Members (the "Claims
         Payment Account"). BJC shall complete such forms as may be required by
         the Bank to grant HCUSA the right to access funds necessary to pay
         claims from the Claims Payment Account. BJC and HCUSA shall jointly
         complete any forms necessary to allow BJC and HCUSA access to Claims
         Payment Account information (including without limitation monthly
         balance statements). The parties acknowledge that the Claims Payment
         Account shall remain the property of BJC and that any interest,
         earnings or other income derived or accrued on the investment of such
         account funds shall also be the property of BJC; provided, however that
         BJC understands and agrees that under no circumstances may BJC directly
         withdraw funds from the Claims Payment Account without the prior
         written consent of HCUSA, which consent shall not be unreasonably
         withheld. HCUSA may withdraw from the Claims Payment Account amounts
         due to health care providers for the provision of Covered Services to
         BJC Medicaid Members, including without limitation, amounts due to BJC
         Providers, Participating Providers and non-Participating providers
         under applicable fee schedules, Customary Charges and other
         fees-for-services and PCP capitation payments (such amounts are
         hereafter collectively referred to as "Claims") in accordance with the
         Claims payment procedures set forth in this Section 3.2. HCUSA shall
         not withdraw or access funds or any moneys from the Claims Payment
         Account or access the BJC Irrevocable Letter of Credit other than for
         the purposes described in this Section 3. HCUSA shall provide BJC
         reports regarding Claims as required elsewhere in this Agreement. At no
         time shall funds in the Claims Payment Account established pursuant to
         this Exhibit A-2 be commingled with funds from any other account or
         Benefit Plans covered under this Agreement or any other Exhibit to this
         Agreement.

         (2) Calculation of Claims Payment Account. On the twentieth (20th) day
         of each calendar month or the next business day in the event the 20th
         day of the month is a Saturday, Sunday or bank holiday, HCUSA shall,
         after collecting and reconciling the premium payment from the State of
         Missouri, calculate and deposit into the Claims Payment Account an
         amount equal to the applicable BJC Premium for all BJC Medicaid Members
         for the immediately preceding calendar month.

         (3) Letter of Credit. BJC shall at all times maintain an Irrevocable
         Letter of Credit (the "BJC ILOC") (the form of which shall be attached
         hereto as EXHIBIT L-2) attached to the Claims Payment Account
         specifically established for BJC Medicaid Member claims pursuant to
         this Exhibit A-2, which may be drawn upon directly by HCUSA in the
         event the Claims Payment Account does not have sufficient funds to pay
         for claims for Covered Services rendered to BJC Medicaid Members. The
         BJC ILOC shall be continuously maintained in an amount equal to three
         months of claims for BJC Medicaid Members averaged over the immediately
         preceding 6 months. BJC shall assure at any time and at all times
         during the any term of this Agreement and any extensions thereof, that
         (1) HCUSA at any time and from time to time may directly access the BJC
         ILOC, (2) HCUSA at any time and at all times has access to information
         on the BJC ILOC and (3) 




                                       40
<PAGE>   41


         the BJC ILOC maintains a continuous minimum available and accessible
         amount equal to 3 months of claims for BJC Medicaid Members averaged
         over the immediately preceding 6 months.


         (4) Claims Payment Procedures and Access to BJC ILOC. On a weekly
         basis, HCUSA shall perform a check run and determine the amount
         necessary to cover the claims adjudicated for BJC Medicaid Members
         during the immediately preceding week. HCUSA shall determine by
         confirming with the bank that the Claims Payment Account contains
         sufficient funds to cover the total amount of that check run and, upon
         receiving such confirmation, HCUSA shall release all checks for claims
         received for BJC Medicaid Members during the immediately preceding
         week. In the event HCUSA receives information from the bank that the
         Claims Payment Account does not have sufficient funds to cover the
         claims, HCUSA shall notify the BJC Contact Person identified pursuant
         to Section 3 of this Agreement of the amount of the shortfall. BJC
         shall then have one business day to transfer the necessary amount via
         ACH transfer from an alternative BJC account into the Claims Payment
         Account. In the event BJC does not complete the ACH transfer, HCUSA may
         without further notice to BJC access the BJC ILOC in the amount
         necessary to cover the total amount of that check run and release the
         checks to cover the total amount of that check run. Within 2 business
         days of HCUSA's completion of accessing the BJC ILOC, BJC shall
         complete any and all steps necessary to maintain the continuous minimum
         BJC ILOC amount available to and accessible by HCUSA as required by
         subsection (3) above.


         (5) Provider Submission of and Adjustments to Claims for Covered
         Services. BJC shall assure that BJC Providers submit claims for BJC
         Medicaid Member Covered Services to Plan in a manner and format
         prescribed by Plan. At Plan's request, BJC Provider may be required to
         submit such claims electronically in a manner and form agreed to by the
         parties and on at least 60 days notice to the BJC Provider. BJC
         Medicaid Member Covered Services claims must be received by Plan no
         more than 60 days from the date the Covered Services were rendered. BJC
         and BJC Provider agrees that claims received from and after 90 days
         from the date BJC Medicaid Member Covered Services were rendered may be
         rejected for payment, at Plan's discretion; provided, however, that
         corrections or additions to such claims shall be considered by Plan if
         made within 30 days from BJC Provider's receipt of the initial claim
         payment.

         Unless otherwise directed by Plan, BJC shall assure that BJC Providers
         submit claims using current HCFA 1500 or UB92 forms with current HCPCS
         coding, if applicable, current ICD9 coding and current CPT coding. BJC
         Providers shall include in a claim the BJC Medicaid DCN Member number
         and BJC Provider's Customary Charge for the Covered Services rendered
         to a BJC Medicaid Member during a single instance of service. BJC
         Provider also shall submit BJC Provider's Federal Tax I.D. number
         and/or other identifiers.

         Plan shall have the right to make corrective adjustments to any
         previous BJC Provider payment for a claim for Covered Services;
         provided, however, that any corrections shall




                                       41
<PAGE>   42

         be made either (1) within 6 months from receipt by Plan of such claim;
         (2) as part of an annual reconciliation procedure; or (3) at any time
         as part of a Plan audit of BJC's or BJC Provider's claims to the extent
         such claims adjustments arise out of billing errors, or improper,
         fraudulent or abusive billing practice.

         (6) Claims Responsibility. The parties understand and agree that under
         state and/or federal statutes and regulations governing insurers, HMOs
         and claims turnaround times/payment procedures, Plan may be required to
         pay any due and outstanding Claims even in the event that amounts then
         in the Claims Payment Account are unavailable to Plan and/or
         insufficient to pay such Claims, putting Plan at risk for Claims
         responsibility contrary to the intent of this Agreement. In the event
         Plan is required to make Claims payments under the circumstances
         described in this subsection 6, BJC agrees that to the extent the funds
         necessary to pay the Claims were not directly and timely available to
         HCUSA under the BJC ILOC, then , BJC shall hold harmless and indemnify
         Plan for any and all payments, losses, claims, liabilities, actions,
         suits, causes of action, administrative or regulatory proceedings,
         costs and expenses arising out of or related to such Claims payments.
         In addition, BJC shall assure that BJC Providers do not bill any BJC
         Medicaid Member for Covered Services if BJC Provider fails to submit
         claims in accordance with the terms and conditions set forth in this
         Agreement (including without limitation this and any other applicable
         Exhibits, appendices, addendums or attachments), and BJC shall
         indemnify and hold harmless Plan and BJC Medicaid Member and the
         Missouri Department of Medical Services for all payments, losses,
         liabilities, claims, suits, actions, causes of action, costs and
         expenses incurred by Plan and BJC Medicaid Member arising out of BJC
         Providers' failure to comply with the prohibition on billing contained
         in this Agreement, including without limitation this and any other
         Exhibits, appendices or attachments.

3.3 ELIGIBILITY AND BENEFIT VERIFICATION. Plan shall be responsible for the
determination whether (i) a person receiving services, supplies, products or
accommodations from a BJC Provider is a BJC Medicaid Member, and (ii) the
services, supplies, products and accommodation provided to a BJC Medicaid Member
are Covered Services. Plan shall provide BJC with the claims and eligibility
reports attached hereto as EXHIBIT E and Plan shall use its reasonable efforts
to provide BJC and BJC Providers in the future with real time access to Plan's
eligibility files to verify BJC Medicaid Member eligibility and coverage. Plan
agrees that its eligibility verification processes shall be reasonable and
consistently and uniformly applied to each BJC Provider. Plan shall make
eligibility determinations according to its then current policies.


3.4 ADJUSTMENTS FOR RETROACTIVE ELIGIBILITY AND BENEFIT DETERMINATIONS: The
parties acknowledge that Plan may from time to time make retroactive adjustments
to eligibility and benefit determinations. Plan agrees to use reasonable efforts
to keep such retroactive determinations to a minimum; eligibility, however, is
controlled by the State of Missouri.


         (1) Retroactive Eligibility Cancellations. If a BJC Medicaid Member's
         eligibility has been canceled retroactively, Plan may deduct from
         deposits to be made into the Claims 



                                       42
<PAGE>   43

         Payment Account an amount equal to the BJC Premium previously deposited
         into the Claims Payment Account on account of the retroactive
         cancellation. BJC shall assure that Plan may recoup from a BJC Provider
         any claims payments made to BJC Providers on behalf of such BJC
         Medicaid Member during such time as the BJC Medicaid Member was not
         eligible. BJC and BJC Providers may then bill State of Missouri if the
         BJC Medicaid Member has become eligible under the Medicaid
         Fee-For-Service program. In the event the BJC Medicaid Member is not
         eligible under the Medicaid Fee-For-Service program, BJC Provider may
         bill the BJC Medicaid Member for services rendered during such period
         of ineligibility using customary billing procedures, which billing
         shall not constitute a violation of the member protection and no
         balance billing provisions set forth in this Agreement.

         (2) Retroactive Eligibility Additions. If a BJC Medicaid Member's
         enrollment in a BJC Provider's practice has been added retroactively,
         Plan shall make a deposit into the Claims Payment Account in an amount
         equal to the BJC Premium received (and Plan shall deduct from the
         Claims Payment Account an amount equal to the claims for Covered
         Services paid on behalf of such BJC Medicaid Member) during the time
         period such BJC Medicaid Member was eligible but not treated as a BJC
         Medicaid Member for claims payment purposes. BJC shall assure that Plan
         may offset and/or recoup from a BJC Provider any claims payments made
         to BJC Providers under another agreement or another Exhibit to this
         Agreement during such time as the BJC Medicaid Member was eligible but
         not treated as a BJC Medicaid Member for claims payment purposes.

The financial terms and conditions set forth in this Section 3.4 shall be BJC
Provider's sole and exclusive remedy for failing to notify Plan of a BJC
Medicare Member's enrollment in BJC Provider's practice.


                      SECTION 4: RECONCILIATION PROCEDURES


4.1 ACKNOWLEDGMENT. The parties understand and agree that because the BJC
Premium and resulting amount paid into the Claims Payment Account differs for
each Benefit Plan covered by this Agreement, and because the payment procedures
differ for BJC Medicare Members, for BJC Members, and for BJC Medicaid Members,
the calculations and reconciliations under this Section 4 shall not be
aggregated and shall be made separately for the Medicaid Benefit Plan, and other
Benefit Plans, if any, included under Section 2 of this Exhibit.

4.2 BJC QUARTERLY WITHDRAWALS FROM CLAIMS PAYMENT ACCOUNT. The parties agree
that from and after the fifteenth month of this Agreement, BJC may request
quarterly withdrawals from the Claims Payment Account. HCUSA shall grant BJC's
request if the Claims Payment Account has sustained a continuous minimum balance
of at least 110% of the average monthly claims payment averaged over the
immediately preceding 12 month period experience.

4.3 ANNUAL PREMIUM RECONCILIATION. Within 180 days after the end of each
calendar year identified in Section 3.1 of this Exhibit, Plan shall calculate
the difference between (i) the BJC Premium Amount for such calendar year less
any BJC Quarterly Withdrawals actually paid to




                                       43
<PAGE>   44

BJC plus any amounts that were actually funded by BJC upon request or drawn upon
or accessed by the BJC ILOC and (ii) the amount of Total Provider Payments made
by Plan for Covered Services provided to BJC Medicaid Members during such
calendar year plus IBNR claims less any amounts actually recovered by Plan from
an applicable reinsurer (the "Premium Reconciliation Amount"). In the event that
the Premium Reconciliation Amount is a positive number Plan shall pay that
amount to BJC within 15 days of the completion of the Annual Premium
Reconciliation. In the event the Premium Reconciliation Amount is a negative
number BJC shall pay that amount to Plan within 15 days after receipt from Plan
of the results of the Annual Premium Reconciliation. Any claims for Covered
Services provided to BJC Medicaid Members which have been presented for payment
or which have otherwise been identified but have not been paid within 150 days
after the end of such calendar year shall be appropriately accrued for and
included in the Annual Premium Reconciliation. Any such claims presented to Plan
for payment following completion of the Annual Premium Reconciliation for a
given calendar year shall be forwarded to BJC and payment of such claims shall
be entirely BJC's responsibility. To the extent that Plan is required to pay any
such claims it may offset such payments against BJC Premium amounts due to BJC
in the future. In the event Plan receives any premium payments for a given
calendar year from which BJC Premiums are required to be calculated after the
completion of the Annual Premium Reconciliation for that calendar year, Plan
shall forward BJC Premiums to BJC.


4.4 FINAL PREMIUM RECONCILIATION. In the event of termination of this Agreement
Plan shall within 180 days of the effective date of termination calculate for
any periods for which Premium Reconciliation Amounts have not already been
calculated and paid (the "Final Reconciliation Period") the difference between:
(i) the BJC Premium Amount for such Final Reconciliation Period less any BJC
Quarterly Withdrawals actually paid to BJC during the Final Reconciliation
Period plus any amounts that were actually funded by BJC upon request or drawn
upon or accessed by the BJC ILOC and (ii) the amount of Total Provider Payments
made by Plan for Covered Services provided to BJC Medicaid Members during the
Final Reconciliation Period plus claims for such Final Reconciliation Period
less any amounts recovered by Plan from an applicable reinsurer not already
calculated (the "Final Premium Reconciliation Amount") calculated consistently
with Plan's other IBNR claims calculations. Any Final Premium Reconciliation
Amounts owed by either party shall be paid within 90 days of receipt of notice
of the Final Premium Reconciliation Amount. Any Premium Reconciliation Amounts
previously calculated as due from one party to the other, but not yet paid shall
be paid at the same time.

4.5 SUPPORTING INFORMATION; PREMIUM RECONCILIATION AUDIT RIGHTS. Within 180 days
after the end of each calendar year and within 180 days of the effective date of
termination of this Agreement Plan shall provide to BJC information
establishing: (i) the Total Premium in respect of such calendar year; (ii) the
Total Provider Payments in respect of such calendar year; and (iii) Plan's
calculation of the BJC Premium amount and the Premium Reconciliation for such
calendar year. BJC shall be entitled to review and to conduct an audit (either
by BJC or by independent auditors acceptable to Plan) of Plan's books and
records to verify such amounts and calculations as claimed by Plan. Any such
review and/or audit shall be conducted at BJC's expense. If as the result of any
such review or audit it is determined that the Premium Reconciliation as
conducted by Plan was incorrect BJC and Plan shall promptly correct the



                                       44
<PAGE>   45

Premium Reconciliation. In the event BJC and Plan are unable after good faith
efforts for at least 60 days to resolve a dispute with regard to any such amount
or calculation such dispute shall be settled in accordance with the dispute
resolution provisions of this Agreement.

4.6 ANNUAL CLAIMS AUDIT RIGHTS. From and after October 1, 1997, BJC shall have
the right to conduct quarterly audits of Plan's performance of the claims
processing and claims payment function under this Agreement, but not more
frequently than two times per year. Such an annual audit shall be conducted at
BJC's sole expense, shall be completed within 180 days of the end of each year
for the immediately preceding year, and shall be performed by a nationally
recognized third party reasonably acceptable to Plan in view of Plan's
reasonable competitive concerns. Such third party shall have access to and be
entitled to review Plan's applicable Participating Provider agreement fee
information, if any, and other books and records necessary to verify whether
claims were correctly paid by Plan. Plan shall be given the opportunity to
comment on the auditor's report prior to release, and all such comments shall be
disclosed to BJC. The auditor's report to BJC shall specifically not include any
blanket references to or specific or general disclosures of Plan's fee schedules
or other rate or payment arrangements with non BJC Providers, but shall instead
confirm to BJC whether Plan correctly paid the amount of the claim in accordance
with the bill or the Plan Participation Agreement in effect with such claimant,
as applicable. In the event the auditor's report to BJC states that Plan has not
paid specific claims correctly, Plan shall use the same efforts it uses in the
ordinary course of business with respect to non-BJC claims to recover the amount
incorrectly paid. Any amounts recovered by Plan shall be deposited into the
Claims Payment Account.

                                   EXHIBIT A-3
                        PAYMENT FOR BJC MEDICARE MEMBERS

                             SECTION 1: DEFINITIONS

COPAYMENT: The amount a Member is required to pay and BJC Provider shall collect
for certain Covered Services in accordance with the Member's Benefit Plan.

CUSTOMARY CHARGE: The reasonable and customary fees charged by a provider,
Participating Provider or BJC Provider ("billed charges") which do not exceed
the billed charges such provider would charge any other person regardless of
whether the person is a Member.

DEDUCTIBLE: The annual amount of charges for Covered Services, as provided in
the Member's Benefit Plan, which the Member is required to pay and which, to the
extent applicable to Covered Services provided by BJC Provider, BJC Provider may
collect in accordance with the Member's Benefit Plan.

BJC MEMBER: A Member who has selected or has been assigned to a BJC Provider
(including without limitation a BJC Provider located in or associated with a
Medical Center) as his or her PCP.

BJC MEDICARE MEMBER: A BJC Member who is covered by a Medicare Cost or a
Medicare Risk product offered by or through Plan.

BJC PREMIUM: The amount of compensation to be paid to BJC for the services to be
provided by or through BJC and BJC Providers, including Covered Services
rendered to BJC Medicare Members. BJC Premium shall be stated in this Exhibit as
a percentage of Total Premium per BJC Medicare Member per month (see section 3.1
below). BJC Providers shall collect from BJC Medicare Members and may retain
collected Copayments, Deductibles or charges for services which are not Covered
Services (whether by reason of an exclusion, exhaustion of benefits, benefit
maximums, and recoveries from coordination of benefits, third party claims and
subrogation to the extent permitted by law, and similar bases, but not amounts
not paid by reason of a UM determination) under a Member's Benefit Plan. Such
collected amounts, if any, shall be in addition to and shall not be deemed part
of the BJC Premium.


TOTAL PREMIUM: The amount of gross premium actually collected and other payments
actually received by Plan to the extent permitted by law for each BJC Medicare
Member per month. The parties acknowledge that due to systems issues, as of the
Effective Date of this Exhibit A-3, for purposes of calculating the amount of
monthly deposits into the Claims Payment Account, (1) for the first month under
this Exhibit A-3 GHP is depositing an amount determined as the average gross
premiums per Member per month for Medicare Risk and for Medicare Cost Members
multiplied by the number of Medicare Risk and Medicare Cost Members who selected
a PCP whose practice was located in the Medical Centers for the immediately
preceding month; (2) for the second and subsequent months of this Exhibit A-3,
GHP is depositing an amount for each Medicare Risk and Medicare Cost Member an
amount determined as the average gross premium




                                       46

*CONFIDENTIAL INFORMATION HAS BEEN OMITTED AND FILED SEPARATELY WITH THE
COMMISSION.



per Member per month multiplied by the total number of BJC Medicare Members for
the immediately preceding month plus or minus the adjustment for the amount
determined as the amount of premium billed plus retroactive accretions and minus
retroactive deletions, if any, (but only to the extent permitted in accordance
with Section 3.6 of this Exhibit A-3) billed by Plan for each BJC Medicare
Member per month who has enriched benefits, plus or minus the adjustment for the
reconciliation for the amount of premium actually collected from the Health Care
Financing Administration ("HCFA") by Plan for each BJC Medicare Member per month
for the immediately preceding month.

TOTAL PROVIDER PAYMENTS: The total amount of payments made by Plan to any
providers, including BJC Providers, for the provision of Covered Services to BJC
Medicare Members incurred during the applicable period (e.g., calendar year).


                           SECTION 2: SCOPE OF EXHIBIT

The provisions of this Exhibit apply to Covered Services rendered to BJC
Medicare Members, regardless of whether such BJC Medicare Members receive
Covered Services from BJC Providers, Participating Providers or
non-Participating Providers within or outside of BJC's Service Sites or within
or outside of Plan's Service Area.

                          SECTION 3: PAYMENT OBLIGATION

3.1 PAYMENT FOR SERVICES. In consideration of BJC's arranging for the provision
of all Covered Services to BJC Medicare Members covered by Benefit Plans within
the scope of this Exhibit, of BJC's assumption of the financial risk associated
with the provision of such Covered Services to BJC Medicare Members, and of
BJC's performance of its obligations under this Agreement, Plan shall pay BJC in
accordance with the payment and claims processing procedures set forth in this
Exhibit A-3. The amount of payment shall be the BJC Premium set forth below:

<TABLE>
<CAPTION>
Calendar Year:                  BJC Premium:
- --------------                  ------------
<S>                             <C>
1997                               [___]*
1998                               [___]*
1999                               [___]*

2003-2007                          [___]*
</TABLE>

In no event shall such percentage be deemed to include the amount or value of
any Copayments or Deductibles, or recoveries from appropriate coordination of
benefits, third party claims or subrogation recoveries to the extent permitted
by law which BJC Providers may be entitled to collect for certain Covered
Services as set forth in BJC Medicare Members' Benefit Plans.


                                       47
<PAGE>   48

3.2 PAYMENT PROCESS FOR BJC MEDICARE MEMBERS. The parties agree that the
following process shall be used to assure the timely payment of claims for BJC
Medicare Members covered by Benefit Plans within the scope of this Exhibit:


         (1) Establishment of Claims Payment Account. The parties shall mutually
         agree upon the bank and type of account into which GHP shall deposit
         BJC Premium and out of which GHP shall process claims for Covered
         Services for BJC Medicare Members (the "Claims Payment Account"). The
         parties acknowledge that the Claims Payment Account may contain BJC
         Premium and BJC Medicare Premium (as that term is defined in Exhibit
         A-3) but not BJC Medicaid Premium (as that term is defined Exhibit
         A-2). BJC shall complete such forms as may be required by the Bank to
         grant GHP the right to access funds necessary to pay claims from the
         Claims Payment Account. BJC and GHP shall jointly complete any forms
         necessary to allow BJC and GHP access to Claims Payment Account
         information (including without limitation monthly balance statements).
         The parties agree that the Claims Payment Account shall remain the
         property of BJC and that any interest, earnings or other income derived
         or accrued on the investment of such account funds shall also be the
         property of BJC; provided, however, that BJC understands and agrees
         that under no circumstances may BJC directly withdraw funds from the
         Claims Payment Account without the prior written consent of Plan, which
         consent shall not be unreasonably withheld. Plan may withdraw from the
         Claims Payment Account amounts due to health care providers for the
         provision of Covered Services to BJC Medicare Members, including
         without limitation, amounts due to BJC Providers, Participating
         Providers and non-Participating providers under applicable fee
         schedules, Customary Charges and other fees-for-services and applicable
         capitation payments (such amounts are hereafter collectively referred
         to as "Claims") in accordance with the Claims payment procedures set
         forth in this Section 3.2. Plan shall not withdraw or access funds or
         any moneys from the Claims Payment Account or the Claims Assurance
         Account other than for the purposes described in this Section 3. Plan
         shall provide BJC reports regarding Claims as required elsewhere in
         this Agreement.

         (2) Calculation of Claims Payment Account. On the fifteenth (15th) day
         of each calendar month or the next business day in the event the
         fifteenth (15th) day of the month is a Saturday, Sunday or bank
         holiday, GHP shall, after calculating Total Premiums and BJC Premium
         for the purpose of determining the deposit amount for each BJC Medicare
         Member per month, calculate and deposit into the Claims Payment Account
         an amount equal to the applicable BJC Premium that Plan collected from
         or on behalf of BJC Medicare Members.

         (3) Letter of Credit. BJC shall at all times maintain an Irrevocable
         Letter of Credit (the "BJC ILOC") (the form of which shall be attached
         hereto as EXHIBIT L) attached to the Claims Payment Account which may
         be drawn upon directly by GHP in the event the Claims Payment Account
         does not have sufficient funds to pay for claims for Covered Services
         rendered to BJC Medicare Members. The BJC ILOC shall be continuously
         maintained in an amount equal to three months of claims for BJC
         Medicare Members averaged over the immediately preceding 6 months. BJC
         shall assure at any time and at




                                       48
<PAGE>   49

         all times during the any term of this Agreement and any extensions
         thereof, that (1) GHP at any time and from time to time may directly
         access the BJC ILOC, (2) GHP at any time and at all times has access to
         information on the BJC ILOC and (3) the BJC ILOC maintains a continuous
         minimum available and accessible amount equal to 3 months of claims for
         BJC Medicare Members averaged over the immediately preceding 6 months.

         (4) Claims Payment Procedures and Access to BJC ILOC.

                  (i)  Non-Capitation Payment Procedures. On a weekly basis, GHP
                  shall perform a check run and determine the amount necessary
                  to cover non-capitation Claims only adjudicated for BJC
                  Medicare Members during the immediately preceding week. GHP
                  shall determine by confirming with the bank that the Claims
                  Payment Account contains sufficient funds to cover the total
                  amount of that non-capitation Claims check run and, upon
                  receiving such confirmation, GHP shall release all checks for
                  such Claims received for BJC Medicare Members during the
                  immediately preceding week. In the event GHP receives
                  information from the bank that the Claims Payment Account does
                  not have sufficient funds to cover such non-capitation Claims
                  check run, GHP shall notify the BJC Contact Person identified
                  pursuant to Section 3 of this Agreement of the amount of the
                  shortfall. BJC shall then have one business day to transfer
                  the necessary amount via ACH transfer from an alternative BJC
                  account into the Claims Payment Account. In the event BJC does
                  not complete the ACH transfer, GHP may without further notice
                  to BJC access the BJC ILOC in the amount necessary to cover
                  the total amount of that non-capitation Claims check run and
                  release the checks to cover the total amount of that check
                  run. Within 2 business days of GHP's completion of accessing
                  the BJC ILOC, BJC shall complete any and all steps necessary
                  to maintain the continuous minimum BJC ILOC amount available
                  to and accessible by GHP as required by subsection (3) above.

                  (ii) Capitation Payment Procedures. On a monthly basis, GHP
                  shall perform a check run and determine the amount necessary
                  to cover Capitation Claims applicable to BJC Medicare Members
                  during the current month. GHP shall determine by confirming
                  with the bank that the Claims Payment Account contains
                  sufficient funds to cover the total amount of the Capitation
                  check run and, upon receiving such confirmation, GHP shall
                  initiate an ACH transfer of sufficient funds from the Claims
                  Payment Account into an account to be designated by GHP and,
                  upon receiving confirmation of the ACH transfer, GHP shall
                  release all checks for that Capitation check run. In the event
                  GHP receives information from the bank that the Claims Payment
                  Account does not have sufficient funds to cover that
                  Capitation check run, GHP shall notify the BJC Contact Person
                  identified pursuant to Section 3 of the Agreement of the
                  amount of the shortfall. BJC shall then have one business day
                  to transfer the necessary amount via ACH transfer from an
                  alternative BJC account into the Claims Payment Account. In
                  the event BJC does not complete the ACH transfer, GHP may
                  without further notice to BJC directly access the BJC ILOC in
                  the amount necessary to cover the total amount




                                       49
<PAGE>   50

                  of that Capitation check run and release the checks to cover
                  the total amount of that Capitation check run. Within 2
                  business days of GHP's completion of accessing the BJC ILOC,
                  BJC shall complete any and all steps necessary to maintain the
                  continuous minimum BJC ILOC amount available to and accessible
                  by GHP as required by subsection (3) above.


         (5) Provider Submission of and Adjustments to Claims for Covered
         Services. BJC shall assure that BJC Providers submit claims for BJC
         Medicare Member Covered Services to Plan in a manner and format
         prescribed by Plan. At Plan's request, BJC Provider may be required to
         submit such claims electronically in a manner and form agreed to by the
         parties and on at least 60 days notice to the BJC Provider. BJC
         Medicare Member Covered Services claims must be received by Plan no
         more than 60 days from the date the Covered Services were rendered. BJC
         and BJC Provider agrees that claims received from and after 90 days
         from the date BJC Medicare Member Covered Services were rendered may be
         rejected for payment, at Plan's discretion; provided, however, that
         corrections or additions to such claims shall be considered by Plan if
         made within 30 days from BJC Provider's receipt of the initial claim
         payment.

         Unless otherwise directed by Plan, BJC shall assure that BJC Providers
         submit claims using current HCFA 1500 or UB92 forms with current HCPCS
         coding, if applicable, current ICD9 coding and current CPT coding. BJC
         Providers shall include in a claim the BJC Medicare Member number and
         BJC Provider's Customary Charge for the Covered Services rendered to a
         BJC Medicare Member during a single instance of service. If requested
         by Plan, BJC Provider shall also submit BJC Provider's Federal Tax I.D.
         number and/or other identifiers.

         Plan shall have the right to make corrective adjustments to any
         previous BJC Provider payment for a claim for Covered Services;
         provided, however, that any corrections shall be made either (1) within
         6 months from receipt by Plan of such claim; (2) as part of an annual
         reconciliation procedure; or (3) at any time as part of a Plan audit of
         BJC's or BJC Provider's claims to the extent such claims adjustments
         arise out of billing errors, or improper, fraudulent or abusive billing
         practices.


         (6) Claims Responsibility. The parties understand and agree that under
         state and/or federal statutes and regulations governing insurers, HMOs
         and claims turnaround times/payment procedures, Plan may be required to
         pay any due and outstanding Claims even in the event that amounts then
         in the Claims Payment Account are unavailable to Plan and/or
         insufficient to pay such Claims, putting Plan at risk for Claims
         responsibility contrary to the intent of this Agreement. In the event
         Plan is required to make Claims payments under the circumstances
         described in this subsection 6, BJC agrees that to the extent the funds
         necessary to pay the Claims were not directly and timely available to
         GHP under the BJC ILOC, then, BJC shall hold harmless and indemnify
         Plan for any and all payments, losses, claims, liabilities, actions,
         suits, causes of action, administrative or regulatory proceedings,
         costs and expenses arising out of or related to such Claims payments.
         In addition, BJC shall assure that BJC Providers do not bill any BJC
         Medicare 



                                       50
<PAGE>   51


         Member for Covered Services if BJC Provider fails to submit claims in
         accordance with the terms and conditions set forth in this Agreement
         (including without limitation this and any other applicable Exhibits,
         appendices, addendums or attachments), and BJC shall indemnify and hold
         harmless Plan and BJC Medicare Member for all payments, losses,
         liabilities, claims, suits, actions, causes of action, costs and
         expenses incurred by Plan and BJC Medicare Member arising out of BJC
         Providers' failure to comply with the prohibition on billing contained
         in this Agreement, including without limitation this and any other
         Exhibits, appendices or attachments.


3.3 ELIGIBILITY AND BENEFIT VERIFICATION. Plan shall be responsible for the
determination under each Benefit Plan covered under the scope of this Exhibit as
to whether (i) a person receiving services, supplies, products or accommodations
from a BJC Provider is a BJC Medicare Member, and (ii) the services, supplies,
products and accommodation provided to a BJC Medicare Member are Covered
Services. Plan shall provide BJC the claims and eligibility reports set forth in
EXHIBIT E and shall use its reasonable efforts to provide BJC and BJC Providers
in the future with real time access to Plan's eligibility files to verify BJC
Medicare Member eligibility and coverage. Plan agrees that its eligibility
verification processes shall be reasonable and consistently and uniformly
applied to each BJC Provider. Plan shall make eligibility determinations
according to its then current policies.


3.4 ADJUSTMENTS FOR RETROACTIVE ELIGIBILITY AND BENEFIT DETERMINATIONS: The
parties acknowledge that Plan may from time to time make retroactive adjustments
to eligibility and benefit determinations. Plan agrees to use reasonable efforts
to keep such retroactive determinations to a minimum, to the extent reasonably
possible using sound business judgment considering the particular Benefit Plan.


         (1) Retroactive Eligibility Cancellations. If a BJC Medicare Member's
         eligibility has been canceled retroactively, Plan may deduct from
         deposits to be made into the Claims Payment Account an amount equal to
         the BJC Premium previously deposited into the Claims Payment Account on
         account of such BJC Medicare Member after the date of the retroactive
         cancellation: provided, however, such amount shall not exceed an amount
         equal to 6 months of BJC Premium for such BJC Medicare Member. BJC
         shall assure that Plan may recoup from a BJC Provider any claims
         payments made to BJC Providers on behalf of such BJC Medicare Member
         during such time as the BJC Medicare Member was not eligible. BJC and
         BJC Providers may then bill such BJC Medicare Member for services
         rendered during such period of ineligibility using customary billing
         procedures, which billing shall not constitute a violation of the
         member protection and no balance billing provisions set forth in this
         Agreement.

         (2) Retroactive Eligibility Additions. If a BJC Medicare Member's
         enrollment in a BJC Provider's practice has been added retroactively,
         Plan shall make a deposit into the Claims Payment Account in an amount
         equal to the BJC Premium received (and Plan shall deduct from the
         Claims Payment Account an amount equal to the claims for Covered
         Services paid on behalf of such BJC Medicare Member) during the time
         period such BJC Medicare Member was eligible but not treated as a BJC
         Medicare Member for




                                       51
<PAGE>   52

         claims payment purposes. Such retroactive adjustments shall be made for
         a period not to exceed 6 months. BJC shall assure that Plan may offset
         and/or recoup from a BJC Provider any claims payments made to BJC
         Providers under another agreement or another Exhibit to this Agreement
         during such time as the BJC Medicare Member was eligible but not
         treated as a BJC Medicare Member for claims payment purposes.

The financial terms and conditions set forth in this Section 3.4 shall be BJC
Provider's sole and exclusive remedy for failing to notify Plan of a BJC
Medicare Member's enrollment in BJC Provider's practice.

3.5 HCFA REQUIRED BENEFIT EXPANSIONS. The parties agree that in the event as the
result of a review by HCFA of Plan's annual filing of the specific Benefit Plan
and range of Covered Services for BJC Medicare Members, HCFA requires Plan to
increase specific Covered Services provided under Plan's Benefit Plan for BJC
Medicare Members, the parties will meet to discuss in good faith a reasonable
resolution to the issue of allocation of financial responsibility for such
specific increased Covered Services.


                      SECTION 4: RECONCILIATION PROCEDURES


4.1 ACKNOWLEDGMENT. The parties understand and agree that because the BJC
Premium and resulting amount paid into the Claims Payment Account differs for
each Benefit Plan and BJC Medicare Member, and because the payment procedures
differ for BJC Medicare Members, for BJC Members, and for BJC Medicaid Members,
the calculations and reconciliations under this Section 4 shall not be
aggregated and shall be made separately for the Medicare Benefit Plan, and other
Benefit Plans included under Section 2 of this Exhibit.

4.2 BJC QUARTERLY WITHDRAWALS FROM CLAIMS PAYMENT ACCOUNT. The parties agree
that from and after the fifteenth month of this Agreement, BJC may request
quarterly withdrawals from the Claims Payment Account. GHP shall grant BJC's
request if the Claims Payment Account has sustained a continuous minimum balance
of at least 110% of the average monthly claims payment averaged over the
immediately preceding 12 month period experience.

4.3 ANNUAL PREMIUM RECONCILIATION. Within 180 days after the end of each
calendar year identified in Section 3.1 of this Exhibit (the "Annual Premium
Reconciliation Period"), Plan shall calculate the difference between (i) the BJC
Premium Amount for such calendar year less the amount of any BJC Quarterly
Withdrawals actually paid to BJC during the Annual Premium Reconciliation
Period, plus the amounts that were actually funded upon request by Plan or drawn
upon or accessed by Plan through the BJC ILOC, and (ii) the amount of Total
Provider Payments made by Plan for Covered Services provided to BJC Medicare
Members during such calendar year plus IBNR claims less any amounts actually
recovered by Plan from an applicable reinsurer (the "Premium Reconciliation
Amount"). In the event that the Premium Reconciliation Amount is a positive
number Plan shall pay that amount to BJC within 15 days of the completion of the
Annual Premium Reconciliation. In the event the Premium Reconciliation Amount is
a negative number BJC shall pay that amount to Plan within 15 days after receipt
from Plan of the results of the Annual Premium Reconciliation. Any claims for
Covered Services provided to BJC 




                                       52
<PAGE>   53

Medicare Members which have been presented for payment or which have otherwise
been identified but have not been paid within 150 days after the end of such
calendar year shall be appropriately accrued for and included in the Annual
Premium Reconciliation. Any such claims presented to Plan for payment following
completion of the Annual Premium Reconciliation for a given calendar year shall
be forwarded to BJC and payment of such claims shall be entirely BJC's
responsibility. To the extent that Plan is required to pay any such claims it
may offset such payments against BJC Premium amounts due to BJC in the future.
Any premium payments received by Plan for a given calendar year from which BJC
Premiums are required to be calculated and which are received after the
completion of the Annual Premium Reconciliation for that calendar year shall be
forwarded to BJC.

4.4 FINAL PREMIUM RECONCILIATION. In the event of termination of this Agreement
Plan shall within 180 days of the effective date of termination calculate for
any periods for which Premium Reconciliation Amounts have not already been
calculated and paid (the "Final Reconciliation Period") the difference between:
(i) the BJC Premium Amount for such Final Reconciliation Period less any BJC
Quarterly Withdrawals actually paid to BJC during the Final Reconciliation
Period, plus any amounts actually funded upon request by Plan or amounts
actually drawn upon or accessed by Plan through the BJC ILOC, and (ii) the
amount of Total Provider Payments made by Plan for Covered Services provided to
BJC Medicare Members during the Final Reconciliation Period plus claims for such
Final Reconciliation Period less any amounts recovered by Plan from an
applicable reinsurer not already calculated (the "Final Premium Reconciliation
Amount") calculated consistently with Plan's other IBNR claims calculations. Any
Final Premium Reconciliation Amounts owed by either party shall be paid within
90 days of receipt of notice of the Final Premium Reconciliation Amount. Any
Premium Reconciliation Amounts previously calculated as due from one party to
the other, but not yet paid shall be paid at the same time.

4.5 SUPPORTING INFORMATION; PREMIUM RECONCILIATION AUDIT RIGHTS. Within 180 days
after the end of each calendar year and within 180 days of the effective date of
termination of this Agreement Plan shall provide to BJC information
establishing: (i) the Total Premium in respect of such calendar year; (ii) the
Total Provider Payments in respect of such calendar year; and (iii) Plan's
calculation of the BJC Premium amount and the Premium Reconciliation for such
calendar year. BJC shall be entitled to review and to conduct an audit (either
by BJC or by independent auditors acceptable to Plan) of Plan's books and
records to verify such amounts and calculations as claimed by Plan. Any such
review and/or audit shall be conducted at BJC's expense. If as the result of any
such review or audit it is determined that the Premium Reconciliation as
conducted by Plan was incorrect BJC and Plan shall promptly correct the Premium
Reconciliation. In the event BJC and Plan are unable after good faith efforts
for at least 60 days to resolve a dispute with regard to any such amount or
calculation such dispute shall be settled in accordance with the dispute
resolution provisions of this Agreement.


4.6 ANNUAL CLAIMS AUDIT RIGHTS. From and after October 1, 1997, BJC shall have
the right to conduct quarterly audits of Plan's performance of the claims
processing and claims payment function under this Agreement, but not more
frequently than two times per year. Such an annual audit shall be conducted at
BJC's sole expense, shall be completed within 180 days of the end of



                                       53
<PAGE>   54

each year for the immediately preceding year, and shall be performed by a
nationally recognized third party reasonably acceptable to Plan in view of
Plan's reasonable competitive concerns. Such third party shall have access to
and be entitled to review Plan's applicable Participating Provider agreement fee
information, if any, and other books and records necessary to verify whether
claims were correctly paid by Plan. Plan shall be given the opportunity to
comment on the auditor's report prior to release, and all such comments shall be
disclosed to BJC. The auditor's report to BJC shall specifically not include any
blanket references to or specific or general disclosures of Plan's fee schedules
or other rate or payment arrangements with non BJC Providers, but shall instead
confirm to BJC whether Plan correctly paid the amount of the claim in accordance
with the bill or the Plan Participation Agreement in effect with such claimant,
as applicable. In the event the auditor's report to BJC states that Plan has not
paid specific claims correctly, Plan shall use the same efforts it uses in the
ordinary course of business with respect to non-BJC claims to recover the amount
incorrectly paid. Any amounts recovered by Plan shall be deposited into the
Claims Payment Account.

                                   EXHIBIT A-4
                       FEE FOR SERVICE PAYMENTS/SCHEDULES

                             SECTION 1: DEFINITIONS

COPAYMENT: The amount a Member is required to pay and BJC Provider shall collect
for certain Covered Services in accordance with the Member's Benefit Plan.

CUSTOMARY CHARGE: The reasonable and customary fees charged by a provider,
Participating Provider or BJC Provider ("billed charges") which do not exceed
the billed charges such provider would charge any other person regardless of
whether the person is a Member.

DEDUCTIBLE: The annual amount of charges for Covered Services, as provided in
the Member's Benefit Plan, which the Member is required to pay and which, to the
extent applicable to Covered Services provided by BJC Provider, BJC Provider may
collect in accordance with the Member's Benefit Plan.

                           SECTION 2: SCOPE OF EXHIBIT

The provisions of this Exhibit apply during the term and any Renewal Term(s) of
this Agreement, Covered Services rendered to Members (i) who have not chosen a
BJC Provider as his or her PCP (and therefore are are not BJC Members, BJC
Medicaid Members or BJC Medicare Members), and (ii) who are covered by all Plan
Benefit Plans including without limitation insured and self-funded (ASO)
products (Benefit Plans) sponsored or issued by all Payors (excluding those
Benefit Plans covered by Exhibits A-1, A-2 and A-3), (iii) when such Members
receive Covered Services from BJC Providers or at a BJC Service Site.


The terms of this Exhibit A-4 and the attached schedules also shall determine
the amounts to be paid to BJC Providers out of the Claims Payment Account(s)
referenced in Exhibits A-1, A-2 and A-3 of this Agreement.

The terms of this Exhibit A-4 and the attached schedules also shall determine
the rates to be paid to BJC Providers during the continuation period reference
in Section 9.4 and Section 10.1 of the Agreement.

               SECTION 3: SERVICE DELIVERY AND PAYMENT OBLIGATIONS

3.1 COVERED SERVICE DELIVERY. BJC and BJC Providers acknowledge and will perform
the obligation to deliver Covered Services to Members in accordance with the
terms of the Agreement and of this Exhibit A-4, including without limitation
Section 3 and Section 4 of the Agreement.

3.2 PAYMENT FOR SERVICES. In consideration of BJC Providers providing or
arranging for the provision of Covered Services to Members covered by Benefit
Plans within the scope of this Exhibit, Payor shall pay BJC Providers in
accordance with the lesser of BJC Provider's 



                                       55
<PAGE>   56


Customary Charges or the payment schedules and procedures set forth in Schedule
A-4 of this Exhibit A-4. In the event a Member possesses other insurance
coverage for Covered Services rendered by a BJC Provider, which pays such BJC
Provider an amount less than the amounts due such BJC Provider under this
subsection 3.2, then the Plan or Payor shall pay such BJC Provider the
difference between what amounts are due under this subsection 3.2 and the amount
paid by to the BJC Provider by the other insurer. The parties agree that to the
extent BJC Providers render Covered Services to Members covered by self-funded
Benefit Plans for which administrative services agreements are entered into by
Plan from and after the Effective Date, Plan shall use its best efforts to
include in its Payor administrative services agreements and obtain from the
Payor an acknowledgment substantially in the form of Schedule A-4 (1) under
which the Payor acknowledges it's obligations as a Payor under the Plan's
provider participation agreements and global capitation arrangements. Plan shall
additionally notify BJC in the event such a self-funded Payor has terminated its
administrative services agreement with Plan or has not satisfied its obligation
to fund the payment of claims. BJC Providers may then pursue payment of Covered
Services from such Members and Payors directly.


3.3 SUBMISSION OF AND ADJUSTMENTS TO CLAIMS FOR COVERED SERVICES. BJC shall
assure that BJC Providers submit claims for Member Covered Services to Plan in a
manner and format prescribed by Plan. At Plan's request, BJC Provider may be
required to submit such claims electronically in a manner and form agreed to by
the parties and on at least 60 days notice to the BJC Provider. Member Covered
Services claims must be received by Plan no more than 60 days from the date the
Covered Services were rendered. BJC Provider agrees that claims received from
and after 90 days from the date Member Covered Services were rendered may be
rejected for payment, at Plan's discretion and may not be directly billed to the
Member or any Payor; provided, however, that corrections or additions to such
claims shall be considered by Plan if made within 30 days from BJC Provider's
receipt of the initial claim payment.


Unless otherwise directed by Plan, BJC shall assure that BJC Providers submit
claims using current HCFA 1500 or UB92 forms with current HCPCS coding, if
applicable, current ICD9 coding and current CPT coding. BJC Providers shall
include in a claim the Member number and BJC Provider's Customary Charge for the
Covered Services rendered to a Member during a single instance of service. If
requested by Plan, BJC Provider shall also submit BJC Provider's Federal Tax
I.D. number and/or other identifiers.

Plan shall have the right to make corrective adjustments to any previous BJC
Provider payment for a claim for Covered Services; provided, however, that any
corrections shall be made either (1) within 6 months from receipt by Plan of
such claim; (2) as part of an annual reconciliation procedure; or (3) at any
time as part of a Plan audit of BJC's or BJC Provider's claims to the extent
such claims adjustments arise out of billing errors, or improper, fraudulent or
abusive billing practices.

3.4 ELIGIBILITY AND BENEFIT VERIFICATION. Plan shall be responsible for the
determination under each Benefit Plan covered under the scope of this Exhibit as
to whether (i) a person receiving services, supplies, products or accommodations
from a BJC Provider is a Member, and 




                                       56
<PAGE>   57

(ii) the services, supplies, products and accommodation provided to a Member are
Covered Services.


3.5 ADJUSTMENTS FOR RETROACTIVE ELIGIBILITY AND BENEFIT DETERMINATIONS: The
parties acknowledge that Plan may from time to time make retroactive adjustments
to eligibility and benefit determinations. Plan agrees to use reasonable efforts
to keep such retroactive determinations to a minimum, and to enforce Benefit
Plan provisions prohibiting such practices by employers to the extent reasonably
possible using sound business judgment considering the particular employer group
and Benefit Plan. The parties acknowledge that subject to the terms of Section
3.1(2) of the Agreement, services provided to an individual when such individual
was not eligible to be a Member will not be Covered Services as defined in this
Agreement or in this Exhibit A-4.

Dear Scott:

There are a number of outpatient surgical procedures commonly performed for a
commercial population that are not classified in the current Medicare groupers.
BIC would therefore like to modify the existing groupers by adding certain CPT
codes to the existing structure.

Please consider the attached list as a first draft to classify these additional
codes.

We would like to discuss these changes with you and these codes, and others we
are considering to the groupers before the transaction is closed. We expect
closing prior to March 31,1997. When we reach mutual agreement, we will modify
the commercial outpatient surgery rates accordingly.

This letter serves as agreement by which both parties to adjust outpatient
surgical codes as discussed above subsequent to the signing of the Global
Capitation Contract of which these rates will be a part of. However, we expect
to reach agreement with you prior to the effective date of the contract.

I would appreciate your response as quickly as possible so that discussions can
get underway.
Please call me with your comments and questions at 996-8106, or Emmette Craft
at 996-8196.

Best regards,

/s/ Charlie

================================================================================

ACUTE CARE          An institution providing medical, surgical, or psychiatric
FACILITY            care and treatment for medical conditions in the acute phase
                    of illness or injury.

SKILLED NURSING     A facility or distinct part of an institution providing
FACILITY            medical, nursing, and other ancillary services to patients
                    requiring restoration or skilled nursing services on a
                    patient basis. Patients who receive care in skilled nursing
                    facilities are not acutely ill but require services above a
                    level of intermediate or custodial care in order to reach an
                    optimal level of functioning.

SUB ACUTE UNIT      A facility or distinct part of an institution that is a step
                    down from acute care for patients who are medically too
                    complex or fragile to be admitted to an inpatient rehab
                    program. Although the patient no longer meets criteria for
                    an acute care, close monitoring and management of their
                    treatment regimen is necessary due to their complicating
                    medical conditions.

INPATIENT SERVICES  Shall mean those Health Services which are provided on an
                    inpatient basis by a duly licensed and accredited hospital
                    or skilled nursing facility.

NURSERY             LEVEL I - Routing care of apparently normal full-term or
                    preterm neonates. ("Newborn Nursery")
                    LEVEL II - Low birth-weight neonates who are not sick, but
                    require frequent feeding, and neonates who require more
                    hours of nursing than do normal neonates. ("Continuing
                    Care")
                    LEVEL III - Sick neonates who do not require intensive care,
                    but require 6-12 hours of nursing each day. ("Intermediate
                    Care")

                                                                    CONFIDENTIAL

                    PICU-Constant nursing and continuous cardiopulmonary and
                    other support for severely ill children. ("Pediatrics")

EMERGENCY ROOM      Emergency Room Services can be divided into the following
SERVICES            levels of care:

                    TRIAGE LEVEL - The initial assessment of patient to include
                    a brief history and limited physical as necessary to
                    determine the appropriate level of care.

                    URGENT CARE LEVEL - The provision of medical services for
                    conditions of sufficient symptoms that without treatment
                    could escalate into more emergent medical complications,
                    loss of life, permanent impairment or that requires early
                    treatment to alleviate pain or severe discomfort.

                    EMERGENCY CARE LEVEL - The provision of medical services
                    for the treatment of a suddenly occurring condition that
                    requires immediate medical attention to prevent loss of
                    life, irreparable physical damage or serious impairment of
                    bodily function*.

REHIBILITATION      The Rehabilitation unit provides a coordinated program of
                    inpatient care that promotes optimal physical,
                    psychological, social, vocational and eduction adjustment,
                    offering individualized treatment programs for a number of
                    diagnoses. These include, but are not limited to:

                    - traumatic brain injury

                    - brain tumors

                    - spinal cord injuries or malformations

                    - strokes

                    - Guillane-Barre syndrome

                    - hypoxic brain injury

                    - severe orthopedic or multiple traumatic injury

                    - post-surgical correction of musculoskeletal problems

                    Patients must be medically stable and neurologically- 
                    responsive to tactile, auditory or visual stimuli. They 
                    also must have the potential to achieve clearly 
                    identifiable treatment goals within a reasonable 
                    length of time.

* "Emergency Care Level" shall be used as an interpretive guideline for
  implementing the definition of "Emergency" as set forth in this Agreement.

ACUTE CARE FACILITY   An institution providing medical, surgical, or
                      psychiatric care and treatment for medical conditions in 
                      the acute phase of illness or injury.

SKILLED NURSING       A facility or distinct part of an institution providing
FACILITY              medical, nursing and other ancillary services to patients
                      requiring restorative or skilled nursing services on a
                      patient basis. Patients who receive care in skilled
                      nursing facilities are not acutely ill but require
                      services above a level of intermediate or custodial care
                      in order to reach an optimal level of functioning.

SUB ACUTE UNIT        A facility or distinct part of an institution that is a
                      step down from acute care for patients who are medically
                      too complex or fragile to be admitted to an inpatient
                      rehab program.  Although the patient no longer meets
                      criteria for an acute care, close monitoring and
                      management of their treatment regimen is necessary due to
                      their complicating medical conditions.

INPATIENT SERVICES    Shall mean those Health Services which are provided on an
                      inpatient basis by a duly licensed and accredited hospital
                      or skilled nursing facility.

NURSERY               LEVEL I - Routine care of apparently normal full-term or
                      preterm neonates.  ("Newborn Nursery")
                      LEVEL II - Low birth-weight neonates who are not sick,
                      but require frequent feeding, and neonates who require
                      more hours of nursing than do normal neonates.
                      ("Continuing Care")   
                      LEVEL III - Sick neonates who do not require intensive
                      care, but require 6-12 hours of nursing each day.  
                      ("Intermediate Care")

                PICU - Constant nursing and continuous cardiopulmonary and other
                support for severely ill children. ("Pediatrics")

EMERGENCY ROOM  Emergency Room Services can be divided into the following
SERVICES        levels of care:

                TRIAGE LEVEL - The initial assessment of patient to include a
                brief history and limited physical as necessary to determine
                the appropriate level of care.

                URGENT CARE LEVEL - The provision of medical services for
                conditions of sufficient symptoms that without treatment could
                escalate into more emergent medical complications, loss of
                life, permanent impairment or that requires early treatment to
                alleviate pain or severe discomfort.

                EMERGENCY CARE LEVEL - The provision of medical services for
                the treatment of a suddenly occurring condition that requires
                immediate medical attention to prevent loss of life,
                irreparable physical damage or serious impairment of bodily
                function.

REHABILITATION  The Rehabilitation unit provides a coordinated program of
                inpatient care that promotes optimal physical, psychological,
                social, vocational and education adjustment, offering
                individualized treatment programs for a number of diagnoses.

                - hypoxic brain injury
                - severe orthopedic or multiple traumatic injury
                - post-surgical correction of musculoskeletal problems

                Patients must be medically stable and neurologically-responsive
                to tactile, auditory or visual stimuli. They also must have the
                potential to achieve clearly identifiable treatment goals
                within a reasonable length of time.

Ladies and Gentlemen:

     1. This Letter of Credit Number S-852087 is issued in your favor and for
the account of BJC (as hereinafter defined) pursuant to a Reimbursement
Agreement dated as of May 1, 1997 (as amended from time to time, the
"Reimbursement Agreement") between the BJC Health System ("BJC") and Mellon
Bank, N.A. (the "Bank"). This Letter of Credit is established for drawing on or
before the Termination Date (as hereinafter defined) of up to the aggregate
amount of $3,370,152.00 (the "Stated Amount") which represents three months of
claims for BJC Medicaid Members as more specifically described in the Global
Capitation Agreement between BJC and Group Health Plan, Inc. (the "Capitation
Agreement").

     2. It is a condition of this Letter of Credit that the Stated Expiration
Date (as hereinafter defined) will be automatically extended annually for a
period of 364 days, unless we notify you in writing at least thirty (30) days
prior to the then current Stated Expiration Date that we elect not to further
extend the Stated Expiration Date of this Letter of Credit. Upon receipt of
such notice, you may draw on this letter of Credit by presenting a sight draft
to us for an amount up to the unused balance of this Letter of Credit on or
before the then relevant expiry date.

     3. Funds under this Letter of Credit are available to you against your
sight draft(s) drawn on us, stating on their face: "Drawn under Irrevocable
Letter of Credit No. S-852087" accompanied by:

          (A) a certificate, in the form of Annex 1 hereto, providing: (i) that
sufficient funds do not exist in the Claims Payment Account (as defined in the
Capitation Agreement); (ii) a demand has been made upon BJC to deliver funds
into the Claims Payment Account pursuant to the Capitation Agreement; (iii) BJC
has failed to deliver such funds; (iv) $_______ is being drawn hereunder in
accordance with such Agreement, which amount represents the amount of such
deficiency; and (v) this amount, together with all other amounts previously
drawn hereunder, does not exceed the Stated Amount;

          (B) a certificate, in the form of Annex 2 hereto, providing that: (i)
the Bank has given you at least 30 days notice that we are not extending the
Stated Expiration Date of this Letter of Credit; and (ii) BJC has not provided
to you a substitute letter of credit for this Letter of Credit which is
satisfactory to you; or

                              DELEGATED FUNCTIONS

                     SECTION 1: DELEGATION OF CREDENTIALING
                     

The parties agree that if BJC's credentialing procedures meet Plan reasonable
standards and guidelines, as mutually agreed to by the parties in accordance
with Section 4 of this Agreement, and the standards and guidelines of any Plan
accrediting organizations including without limitation NCQA, Plan shall delegate
the responsibility for credentialing Providers to BJC; however, Plan retains the
right to approve new health care providers and sites and to terminate or suspend
individual Providers in accordance with the standards and guidelines described
above. If such such function is delegated to BJC, BJC shall comply with the 
following requirements:

1.1     BJC agrees that current and future health care providers that join BJC
must be properly credentialed before they may render Covered Services to Members
pursuant to this Agreement. In addition, BJC shall immediately notify Plan in
writing of all new Providers who become affiliated with and are credentialed by
BJC, as well as those who are no longer affiliated with BJC, and BJC shall
cooperate with Plan's timelines and schedules related to the production of
accurate provider directories.

1.2    BJC shall maintain all records necessary for Plan to monitor the
effectiveness of BJC's credentialing and recredentialing process, including
without limitation records related to the credentialing of all current or
future Providers ("Provider Records"). Annually, BJC shall provide the Plan
with its Credentialing Policies for review and evaluation and shall permit and
cooperate with the Plan's on-site review of BJC's Provider Records, which shall
be conducted by the Plan during BJC's normal business hours and with reasonable
prior notice given. The Plan's on-site review shall consist of its review of the
lesser of five percent (5%) or fifty (50) of BJC's Provider Records to ensure
compliance with the standards of the Plan, NCQA and any other of Plan's
accrediting organizations, and all applicable Federal and state laws and
regulations. BJC shall furnish the Plan with each Provider's signed
authorization permitting the Plan to review such Provider Records, in a form
that provides a release of liability to the Plan and its authorized
representatives in conjunction with conducting such reviews.

1.3     BJC shall submit to Plan credentialing and recredentialing reports
("Reports") that identify those Providers credentialed/recredentialed, the
effective date of such action, the most recent prior date of
credentialing/recredentialing and the effective date of such Providers'
participation with the Plan and the other information set forth in the
incorporated Schedule H. Such reports shall be furnished to the Plan by BJC
after each credentialing committee meeting, without regard to the number of or
frequency of such meetings.

                                      -1-

<PAGE>   227
1.4  Plan shall provide BJC written notice and description of any deficiencies
in BJC's credentialing process and recommendations regarding correction of
same. BJC agrees to correct, within the reasonable timeframes specified Plan,
any such deficiencies and provide Plan written notice of such correction within
the same period, after which Plan will provide BJC with a date for re-review of
such corrected issue.

1.5  To the extent BJC fails to comply with any obligation regarding
credentialing as outlined herein, and fails to correct such situation to Plan's
reasonable satisfaction within thirty (30) days of written notice from Plan of
such defect, Plan shall have the right, to revoke and take over some or all of
the credentialing responsibilities delegated to BJC.


                SECTION 2: DELEGATION OF UTILIZATION MANAGEMENT

The parties agree that if BJC's UM policies and procedures meet Plan standards
and guidelines as mutually agreed to by the parties in accordance with Section
4 of this Agreement, and the standards and guidelines of any Plan accrediting
organizations including without limitation NCQA, Plan shall delegate the
responsibility for initial UM determinations to BJC; however, Plan retains the
right to address and resolve any Member and Provider appeals of BJC's UM
determinations and for all Provider UM determinations. If such such function is
delegated to BJC, BJC shall comply with the following requirements:

     2.1  If the Plan delegates the responsibility of making initial utilization
     management ("UM") determinations ("Determinations") to BJC pursuant to this
     Agreement, BJC shall make such Determinations in accordance with the UM
     policies prepared or approved by the Plan, the terms of the Member's
     Benefit Plan and the Employee Retirement Income and Security Act of 1974
     ("ERISA").

     2.2  In the event of such delegation, BJC shall maintain a UM program
     description and policies and procedures that are in compliance with the
     Plan's reasonable standards and the NCQA standards for Utilization
     Management. The UM program description will include BJC's mechanism for
     handling initial determinations and denials and the communication and
     provision of all information pertaining to same to Plan for its handling of
     UM appeals. Annually, BJC shall provide the Plan with a current UM program
     description, policies and procedures, and the criteria used for medical
     review. BJC shall also provide the Plan with monthly UM reports in such
     time frames as are mutually agreed to by the parties in such form and
     content as specified in the incorporated Schedule H.

     2.3  The Plan shall provide written feedback to BJC following its review
     and evaluation of the UM program descriptions and policies and procedures
     within thirty (30) days of Plan's UM Committee's review of said documents.


                                      -2-

     2.4  Upon rendering an initial determination ("Determination"), BJC shall
     promptly notify a Member, in writing, of Determination, along with an
     explanation of his or her right to appeal that Determination to the Plan in
     accordance with the Member grievance procedure of his or her their Benefit
     Plan. In the event of such appeal, BJC shall promptly furnish the Plan with
     all relevant information and documentation regarding the Member's
     complaint/grievance, all relevant information and documentation pertaining
     to BJC's Determination and the Member's request for appeal. The form of

                            GUARANTY OF PERFORMANCE
                            -----------------------


     THIS GUARANTY OF PERFORMANCE (the "Guaranty") is made and entered into as
of the 1st day of May, 1997 by BJC HEALTH SYSTEM (SM) (the "Guarantor") in favor
of GROUP HEALTH PLAN, INC. ("GHP").

     WHEREAS, BJC and GHP have entered into a Global Capitation Agreement dated
March 12, 1997 (the "Agreement");

     WHEREAS, BJC may desire in the future to assign said Agreement to an entity
under common control with, controlled by, or controlling BJC ("Assignee") in
accordance with the provisions of Section 10.5 of the Agreement; and

     WHEREAS, Guarantor is willing to guaranty the obligations of Assignee under
the Agreement.

     NOW, THEREFORE, in consideration of the foregoing and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, and in accordance with the requirement of Section 10.5 of the
Agreement, Guarantor agrees as follows:

     1. Guarantor unconditionally and absolutely guaranties the punctual payment
(when and as due, without extension) of all payments of any kind and nature now
or hereafter payable to Assignee to GHP under the Agreement, and the observance
of every condition, covenant and obligation of Assignee under the Agreement.
This Guaranty shall remain in full force and effect until the obligations of
Assignee under the Agreement have been performed in full. This Guaranty shall
apply to the Agreement and all extesions, renewals and modifications thereof and
shall be deemed to be a continuing guaranty.

     2. The obligations of Guarantor hereunder shall not be impaired, modified,
released or limited in any way by any impairment, modification, release or
limitation of liability of the Assignee or Assignee's estate in bankruptcy
resulting from the operation of any bankruptcy or insolvency laws or related
proceedings affecting Assignee. No obligation of Guarantor hereunder shall be
deemed to be waived or released as a result of any extension of time for
payment, waiver or forbearance granted at any time by GHP To Assignee.

     3. Guarantor agrees that GHP and Assignee may extend the time of payment,
and renew or change the manner, place, time and terms of payment of and make any
other changes with respect to any or all of the obligations of Assignee under
the Agreement, as and to the extent permitted by the Agreement, and this
guaranty shall apply to the Agreement as so extended, renewed or changed.
<PAGE>   252


     4.  Guarantor agrees that GHP may in its sole and absolute discretion
release and otherwise deal with any other guarantor or guarantors, may exercise
or refrain from exercising any rights against Assignee or any other guarantor
or guarantors or otherwise act or refrain from acting, and may settle or
compromise any or all of Assignee's obligations, under the Agreement, all
without releasing the Guarantor from its obligations thereunder.

     5.  Guarantor shall have no right of subrogation, reimbursement,
contribution or indemnity whatsoever, and no right of recourse to or with
respect to any assets or property of any guarantor or guarantors or to any
collateral owned by Assignee, for the obligations of Assignee guaranteed
hereunder unless and until all of said obligations shall have first been paid
in full to GHP or otherwise satisfied.  Nothing shall discharge or satisfy the
liability of the Guarantor hereunder except the full performance and payment to
GHP of all the said obligations of Assignee and all obligations of the
Guarantor hereunder and, after demanding performance of the Assignee, and
failure of the Assignee to perform, GHP may, at its sole discretion, proceed
directly against Guarantor without first proceeding against Assignee or any
other guarantor or guarantors hereunder.

     6.  Guarantor hereby waives notices of acceptance of this Guaranty by GHP
and notice of execution or commencement of the Agreement.

     7.  Guarantor shall pay to GHP all costs and expenses incurred by GHP in
enforcing this Guaranty, including reasonable attorney fees, regardless of
whether or not litigation is commenced.

     8.  This Guaranty cannot be changed or terminated orally, shall be
governed by and construed in accordance with the laws of the State of Missouri
and shall be binding on and inure to be benefit of the successors and assigns
of the Guarantor and GHP.

     IN WITNESS WHEREOF, this Guaranty is made as of the date first written
above.

*NOTE: The Small Business Administration (SBA) establishes small business size
standards on an industry-by-industry basis in its regulations at 13 CFR 121, as
amended (the "SBA regulations"). For each industry classification, the SBA
regulations set forth the maximum number of employees or annual receipts that
are allowed for a concern (including affiliates) to still be considered small,
but these thresholds vary by industry. For example, the number of employees
allowed generally ranges from 500 to 1,000 depending on the industrial
classification. Contractor should refer to the SBA regulations to assist it in
answering these questions.
