2    DUTIES OF PCP.

     2.1  PCP'S RESPONSIBILITIES. During the Term (as defined below), PCP shall
          provide Primary Care Services to Members within the Service Area in
          accordance with the terms and conditions of this Agreement, and shall
          be available, either through PCP or a Covering Physician, twenty-four
          (24) hours per day, seven (7) days per week, to provide Primary Care
          Services to Members in PCP's office and arrange or provide Primary
          Care Services to Members in any inpatient facility. PCP shall maintain
          an appropriately staffed office within the Service Area to provide
          Primary Care Services to Members. PCP or a Covering Physician shall
          maintain appropriate staff privileges with at least one Participating
          Hospital in the Service Area. PCP shall comply with the PCP
          Requirements set forth on Schedule 2.1, attached hereto and
          incorporated herein, and VISTA Policies.

     2.2  STANDARD OF CARE. All Primary Care Services provided by PCP shall be
          provided in accordance with professionally recognized standards of
          health care and VISTA Policies.

     2.3  REFERRALS AND PRE-AUTHORIZATIONS. PCP shall make appropriate Referrals
          and obtain required Pre-Authorizations for all Covered Services in
          accordance with this Agreement, the applicable VISTA Coverage Plan and
          VISTA Policies. PCP shall use his/her best efforts to provide Members
          with any necessary Referral or obtain any required Pre-Authorization
          from VISTA while the Member is in PCP's office. VISTA shall use its
          best efforts to provide requested Pre-Authorization immediately upon
          PCP's request; provided, however, that PCP agrees to take a pending or
          tracking number with respect to a Pre-Authorization request in the
          event VISTA requires further information in making the
          Pre-Authorization coverage decision. Except in the case of Emergency
          Services or Urgently Needed Services or upon the prior written
          approval of VISTA's Medical Director or his/her designee, PCP agrees
          that all charges incurred for Covered Services by VISTA which fail to
          comply with VISTA's Referral and Pre-Authorization requirements,
          including those set forth in VISTA Policies or the applicable VISTA
          Coverage Plan, shall be borne by PCP, including all related costs,
          fees, charges and expenses. PCP hereby agrees to indemnify and hold
          harmless Members, AHCA, CMS and OIR against charges for Covered
          Services for which PCP failed to comply with VISTA's Referral and
          Pre-Authorization requirements, as required under VISTA Policies, the
          applicable VISTA Coverage Plan or this Agreement.

     2.4  PARTICIPATING PROVIDERS. Except in the case of Emergency Services,
          Urgently Needed Services, as otherwise permitted under VISTA Policies
          or applicable state or federal law, upon the prior written approval of
          VISTA's Medical Director or his/her designee, or as otherwise
          permitted under the applicable VISTA Coverage Plan, all Referrals and
          Pre-Authorizations for Covered Services, including, but not limited to

PCP

                                       2



          ancillary services such as laboratory and radiology services, shall be
          made to Participating Providers in accordance with VISTA Policies. Any
          laboratory services provided to Members in PCP's office shall not be
          reimbursable Covered Services, unless otherwise expressly provided in
          Schedule 4.1 hereof. If PCP fails to comply with this Section 2.4, PCP
          shall be responsible for all charges incurred for Covered Services by
          VISTA rendered by a Non-Participating Provider without the required
          Pre-Authorization, including all related costs, fees, charges and
          expenses. PCP hereby agrees to indemnify and hold harmless Members,
          AHCA, CMS and OIR against charges for Covered Services rendered by a
          Non-Participating Provider for which PCP failed to obtain the required
          Pre-Authorization.

     2.5  COVERING PHYSICIANS. PCP shall make necessary and appropriate
          arrangements with Covering Physicians to ensure the availability of
          Primary Care Services to Members twenty-four (24) hours per day, seven
          (7) days per week, including arrangements to ensure coverage of
          Members after hours or when PCP is otherwise unavailable. PCP shall
          ensure that Covering Physicians are Participating Providers, except as
          otherwise consented to by VISTA in writing. PCP shall ensure that
          Covering Physicians adhere to the terms of this Agreement and all
          VISTA Policies and that Covering Physicians seek required
          Pre-Authorization from VISTA, or Refer the Member back to PCP, as
          required by VISTA Policies, except for Emergency Services or Urgently
          Needed Services or as otherwise permitted under the applicable VISTA
          Coverage Plan. Except for Hospitalist Physicians (as defined below),
          with respect to Capitated Services (as defined below), PCP shall be
          solely liable to Covering Physicians for the amount and manner in
          which Covering Physicians are reimbursed or otherwise compensated for
          services rendered to Members on PCP's behalf. PCP acknowledges and
          agrees that VISTA shall not have any financial obligation whatsoever
          to Covering Physicians with respect to Capitated Services. PCP shall
          ensure that Covering Physicians do not, under any circumstances, bill
          Members for Covered Services other than for applicable Co-Payments,
          Deductibles and Co-Insurance. PCP hereby agrees to indemnify and hold
          harmless Members, AHCA, OIR, and CMS against charges for Covered
          Services rendered by Covering Physicians. All charges incurred for
          services rendered pursuant to a Pre-Authorization or Referral made by
          a Covering Physician, other than a Referral back to PCP, shall, unless
          such Pre-Authorization or Referral was approved by VISTA in advance
          and in writing or as otherwise permitted under the applicable VISTA
          Coverage Plan, be borne by PCP who shall be liable for all costs,
          fees, charges and expenses associated with such services.

     2.6  COORDINATION OF BENEFITS. PCP agrees that payment for Covered Services
          provided to Members is subject to coordination with any other benefits
          payable or paid to or for a Member. Such benefits include, but are not
          limited to, any group insurance coverage, contract, prepayment plan or
          governmental program and any claims that may give rise to compensation
          to a Member from a third party, including, without limitation,
          workers' compensation and automobile insurance. VISTA shall be
          subrogated to all rights of recovery of a Member against any person or
          entity for such

PCP

                                       3



          benefits or payments as permitted under applicable law and this
          Agreement. PCP shall use its best efforts to determine whether a
          Member has any benefits as described above or whether a third party
          may be responsible for payment. PCP shall assist VISTA in coordination
          of benefits by (i) requiring a Member so covered to sign all necessary
          documents to give effect to this Section 2.6; and (ii) signing any
          other document and providing any other information or records so
          requested by VISTA at no cost to VISTA. Unless otherwise required by
          law, PCP shall not be entitled to reimbursement by any third party for
          Covered Services rendered to Members, including, Medicare
          intermediaries or carriers, and all sums recovered pursuant to this
          Section 2.6 shall be retained by VISTA. Unless required by law or the
          applicable VISTA Coverage Plan, in the event VISTA is the primary
          carrier, payments made by VISTA to PCP plus allowed Co-Payments,
          Deductibles and Co-Insurance shall be deemed payment in full for all
          services rendered by PCP hereunder. In the event VISTA is the
          secondary carrier (except in the case of Medicare or where otherwise
          required by law), VISTA shall pay for all services rendered to Members
          in accordance with this Agreement and applicable law that were not
          paid by the primary carrier; provided, however, that the combined
          payments made by the primary and secondary carriers shall not exceed
          one hundred percent (100%) of the compensation due PCP by VISTA under
          Schedule 4.1 of this Agreement. If VISTA is the secondary carrier to
          Medicare, VISTA's liability shall be limited to Deductible and
          Co-Insurance amounts, unless otherwise required by federal law.

     2.7  COLLECTION OF CHARGES FROM MEMBERS. PCP agrees that in no event,
          including but not limited to non-payment by VISTA, insolvency of
          VISTA, or breach of this Agreement, shall PCP, or any representative
          of PCP, bill, charge, collect a deposit from, seek compensation,
          remuneration or reimbursement from, or have any recourse against
          Members or persons (other than VISTA) acting on a Member's behalf for
          Covered Services provided pursuant to this Agreement, including but
          not limited to any and all amounts equal to the difference between
          PCP's Billed Charge for a Covered Service and the applicable Allowance
          for the particular Covered Service. Additionally, PCP, or any
          representative of PCP, shall not collect or attempt to collect money
          from, maintain any action at law against, or report to a credit agency
          a Member for payment of a claim for a Covered Service for which VISTA
          is liable if PCP in good faith knows or should know that VISTA is
          liable in accordance with Florida law, including, but not limited to
          pended claims submitted by PCP to VISTA for payment of the services
          and any legal proceedings or dispute resolution process to determine
          whether VISTA is liable for the services. Notwithstanding the
          foregoing, this Agreement does not prohibit PCP from collecting
          Co-Payments, Deductibles and Co-Insurance, as specifically provided in
          the applicable VISTA Coverage Plan, or fees for non-Covered Services
          delivered on a fee-for-service basis to Members. Nor does this
          Agreement prohibit PCP and a Member from agreeing to continue services
          solely at the expense of the Member, as long as PCP clearly informed
          the Member in advance and in writing that VISTA might not cover or
          continue to cover such specific service(s). PCP shall bill Members
          directly for any applicable Co-Payments, Deductibles and Co-Insurance
          at the time Covered Services are rendered. PCP

          further agrees that this Section 2.7 (i) shall survive the termination
          of this Agreement regardless of the cause giving rise to such
          termination and shall be construed to be for the benefit of Members;
          and (ii) supersedes any oral or written agreement to the contrary now
          existing or hereafter entered into between PCP and a Member or persons
          acting on a Member's behalf. PCP agrees that if non-Covered Services
          are to be provided to Members, it is PCP's responsibility to inform
          the Member in writing prior to the provision of such non-Covered
          Services that such services are not Covered Services and that the
          Member will be responsible for payment for such non-Covered Services
          and to collect the fees for such non-Covered Services directly from
          the Member. In the event that the Member is not so informed, PCP
          agrees that the Member shall not be liable to PCP for payment for such
          non-Covered Services.

     2.8  PUBLICATION AUTHORIZATION. PCP agrees that VISTA may use PCP's name,
          address and telephone number in VISTA's provider directory and other
          marketing materials; provided, however, that VISTA shall have no
          obligation to include PCP's name or other information in VISTA's
          provider directory. PCP shall not advertise or market VISTA, any VISTA
          Affiliate or any of their health care services or Benefit Programs, or
          utilize any trademarks, trade names, logos or other VISTA property
          without VISTA's prior written approval.

     2.9  NONDISCRIMINATION. PCP represents and warrants to VISTA that PCP shall
          not discriminate against Members with respect to the availability or
          provision of health services based on a Member's race, sex, age,
          religion, place of residence, HIV status, source of payment, VISTA
          membership, color, sexual orientation, marital status or any factor
          related to a Member's health status, including, but not limited to, a
          Member's medical condition (including  mental as well as physical
          illness), claims experience, receipt of health care, medical history,
          genetic information, evidence of insurability (including conditions
          arising out of acts of domestic violence), disability or on any other
          basis otherwise prohibited by state or federal law. Further, PCP shall
          comply with Title VI of the Civil Rights Act of 1964, as implemented
          by regulations at 45 C.F.R. part 84; the  Rehabilitation Act of 1973;
          the Americans with Disabilities Act; the Age Discrimination Act of
          1975, as implemented by regulations at 45 C.F.R. part 91; other laws
          applicable to recipients of federal funds; and all other applicable
          laws and rules, as required by applicable laws or regulations. PCP
          shall not  discriminate against a Member based on whether or not the
          Member executed an advance directive.

     2.10 COMPLIANCE WITH REQUIREMENTS OF CMS. PCP shall comply with any and all
          applicable Medicare laws, regulations, CMS instructions and VISTA's
          obligations under its contract with CMS with respect to the provision
          of Covered Services and all other activities relating to Medicare
          Members. PCP represents and warrants that he/she participates as a
          provider under Title XVIII of the Social Security Act (Medicare) in
          accordance with 42 C.F.R. Part 422, and shall maintain such
          participation throughout the Term. Further, PCP shall allow CMS to
          evaluate the quality, appropriateness, and timeliness of Primary Care
          Services rendered by PCP to

PCP

                                        5



          Medicare Members and shall comply with and abide by the results of any
          grievance procedures adopted by CMS.

     2.11 ENCOUNTER DATA. As required by VISTA and applicable law, PCP shall
          submit complete Encounter Data to VISTA on a monthly basis on or
          before the last day of each month, or such lesser time period as may
          be required by VISTA or applicable law, for encounters occurring in
          the immediately preceding month. PCP shall submit Encounter Data in
          accordance with VISTA Policies or as otherwise required by VISTA or
          state or federal laws or regulations, and shall certify the accuracy,
          completeness and truthfulness of such Encounter Data in such form as
          required by VISTA Policies. PCP acknowledges and agrees that in the
          event PCP fails to comply with this Section 2.11, (i) VISTA may
          withhold any and all payments due by VISTA to PCP until such time as
          VISTA receives the current and complete Encounter Data that it
          requested; and (ii) such failure may be deemed a material breach of
          this Agreement, as determined by VISTA in VISTA's sole discretion.

     2.12 SUSPENSION. If PCP is the subject of a notice of suspension,
          limitation or restriction on PCP's license to practice medicine in any
          jurisdiction or is excluded from or voluntarily opts out of the
          Medicare or Medicaid program, PCP shall not render any services to
          Members during such period of suspension, exclusion or
          non-participation or violate the terms of such suspension, limitation,
          restriction or exclusion, unless otherwise permitted by VISTA in
          accordance with applicable law; and, further, PCP shall notify VISTA
          of such suspension, limitation or restriction of his/her license or
          exclusion from or non-participation in the Medicare or Medicaid
          program in accordance with Schedule 2.1. Any Member seeking Primary
          Care Services from PCP during such period of suspension, exclusion or
          non-participation, or requiring Primary Care Services which PCP is
          then restricted or limited from providing, may be referred by VISTA to
          another Primary Care Physician for such Primary Care Services upon
          receipt by VISTA of any such  notice. In the event PCP's license is
          suspended, limited, or restricted or PCP is excluded from or does not
          participate in the Medicare or Medicaid program, VISTA shall have the
          right to terminate any and all payments due to PCP from VISTA under
          this Agreement during such period of suspension, limitation,
          restriction, exclusion or non-participation.

     2.13 VERIFICATION OF ELIGIBILITY. Prior to providing any services to a
          Member, PCP shall cause the Member to produce his/her VISTA membership
          card or, if the Member represents that such membership card was not
          yet issued by VISTA, the Member's enrollment form. VISTA shall make
          reasonable efforts to confirm or deny eligibility using the most
          current information provided by the Subscriber Group, CMS or any other
          governmental agency, as applicable; provided, however, that PCP's
          compliance with such verification procedures and/or VISTA's
          confirmation of a Member's eligibility does not constitute a guarantee
          of such Member's eligibility or VISTA's coverage of any services
          provided by PCP in reliance on such confirmation. In the event VISTA
          determines that a Member was ineligible at the time services were
          provided by PCP to such Member, VISTA may recover payments made by
          VISTA to PCP for that Member retroactive to the first (1st) day of the
          month in which the

PCP
October 4, 2004

                                       6



          Member became ineligible for coverage. VISTA may retroactively add
          Members to PCP's panel for a period of up to ninety (90) days from the
          date VISTA determines, in VISTA's sole discretion, that the particular
          Member should have been included in PCP's panel and PCP shall receive
          applicable Capitation Fee payments on behalf of that Member for such
          period. If, in VISTA's determination, a Member was erroneously or
          inappropriately placed on PCP's Member list or is retroactively
          terminated, VISTA may offset any payment previously paid to PCP on
          behalf of such Member for a period of up to one (1) year from future
          payments due to PCP; provided, however, that such one (1) year
          limitation shall not apply to Members covered under Federal Employee
          Health Benefit Program, Healthy Kids, Medicare or Medicaid pursuant to
          an adjustment made by CMS, AHCA or other applicable entity. If the
          Member loses eligibility during hospitalization, PCP may collect from
          the Member any amounts for services rendered subsequent to the loss of
          coverage under the applicable VISTA Coverage Plan; provided, however,
          that any such loss of eligibility shall be subject to applicable law,
          the applicable VISTA Coverage Plan and VISTA Policies.

     2.14 CONSULTATIONS. PCP shall participate in all programs instituted by
          VISTA to consult with its Participating Providers regarding VISTA
          Policies to assure compliance with federal, state and Accreditation
          Organization standards.

     2.15 PROVISION OF TREATMENT OPTIONS. PCP shall provide information in a
          culturally-competent manner to all Members and consider and take
          measures to accommodate, at PCP's sole cost and expense, Members'
          English proficiency, reading skills, diverse cultural and ethnic
          backgrounds and physical or mental disabilities, including but not
          limited to hearing and vision impairments, when discussing a Member's
          treatment options, including the option of no treatment.

     2.16 DIRECT ACCESS AND COST-SHARING. PCP shall, as mandated by state or
          federal law, the applicable VISTA Coverage Plan and VISTA Policies;
          allow Members direct access to certain Specialist Physicians; not
          inhibit Members' self-referral for certain services, including
          mammography screening and influenza vaccinations; and not impose
          cost-sharing on any Member for influenza or pneumococcal vaccines.

     2.17 DISPARAGEMENT PROHIBITED. PCP shall not disparage VISTA, any VISTA
          Affiliate or any VISTA Coverage Plan in any form or manner whatsoever.
          In the event PCP is determined to have disparaged VISTA, any VISTA
          Affiliate or any VISTA Coverage Plan, in VISTA's sole determination,
          such action by PCP may constitute a material breach of this Agreement,
          as determined by VISTA.

     2.18 CONSUMER ASSISTANCE NOTICE. PCP shall post a prominently displayed and
          clearly noticeable consumer assistance notice in PCP's reception area
          which states the addresses and toll-free telephone numbers of AHCA,
          the Subscriber Assistance Program and OIR and states that the address
          and toll-free telephone number of VISTA's grievance department shall
          be provided upon request.

          comply with and abide by VISTA Policies. PCP's failure to comply with

          that physicians contracted, directly or indirectly, with VISTA are
          responsible for certain Primary Care Services ("Hospitalist
          Physicians") PCP is otherwise obligated to provide under this
          Agreement on behalf of Members assigned to or who select PCP as their

          department or are inpatients of a hospital. Except in cases where PCP
          elects not to participate in the Program, PCP shall not document any
          progress notes in the PCP Member's record or issue any orders on

          Members, including, but not limited to (i) resuming responsibility for

     3.1  LIMITATION ON SELECTION OF PCP. VISTA may limit, restrict or suspend
          Members' opportunity to select PCP for Primary Care Services,
          effective immediately upon written notice to PCP. PCP shall comply

     3.2  ACCOUNTABILITY TO CMS. To the extent required by law, VISTA shall
          oversee and be accountable to CMS with respect to those services

4    COMPENSATION.

     4.1  PAYMENT FOR PRIMARY CARE SERVICES. As compensation in full for Primary
          Care Services provided by PCP under this Agreement, VISTA shall pay
          PCP as set forth in Schedule 4.1 and the Exhibits thereto, attached
          hereto and incorporated herein, as amended by VISTA from time to time
          in VISTA's sole discretion in accordance with Section 9.5 of this
          Agreement. PCP agrees that the compensation paid by VISTA to PCP
          pursuant to Schedule 4.1, plus any applicable Co-Payments, Deductibles
          and Co-Insurance shall serve as full and complete compensation to PCP
          for all Primary Care Services rendered to Members under this
          Agreement, both in PCP's office and in an inpatient setting. To the
          extent required by law, VISTA shall provide PCP with additional
          information regarding VISTA's payment to PCP for Primary Care Services
          provided by PCP under this Agreement upon PCP's request. With respect

                                       9



          Medicare Members, PCP acknowledges that VISTA is receiving federal
          funds and that payments to PCP for Covered Services under this
          Agreement may be, in whole or in part, from federal funds. To the
          extent required by law, PCP shall be subject to all laws applicable to
          entities receiving federal funds. PCP acknowledges the limitation on
          collection of charges from Members, including, without limitation,
          that set forth in Section 2.7 hereof.

     4.2  UTILIZATION-RELATED COMPENSATION. PCP acknowledges and agrees that any
          and all decisions rendered by VISTA in its administration of this
          Agreement, including, but not limited to, all decisions rendered in
          connection with VISTA's utilization management activities are based
          solely on whether such services are covered under the applicable VISTA
          Coverage Plan. Further, PCP acknowledges and agrees that VISTA does
          not compensate PCP for denial of care or services and VISTA does not
          offer incentives to encourage denial of care or services. PCP
          recognizes that there is a need for special concern about
          underutilization of care and services.

     4.3  MULTIPLE AGREEMENTS. Notwithstanding Section 9.15 hereof, if PCP is a
          party to more than one agreement with VISTA or a VISTA Affiliate for
          the provision of Covered Services to Members, VISTA shall have the
          right to determine, in VISTA's sole discretion, whether this Agreement
          or such other agreement governs with respect to the amount of
          reimbursement for Covered Services provided to a particular Member
          which VISTA is obligated to pay PCP.

     4.4  MEMBER RESPONSIBILITY. PCP acknowledges and agrees that VISTA shall
          have no financial or other liability with respect to a Member's
          failure to pay PCP amounts due PCP for Co-Payment, Co-Insurance, or
          Deductible as required under the Member's VISTA Coverage Plan or for
          non-Covered Services.

     4.5  EMERGENCY SERVICES. VISTA shall pay for all Emergency Services
          provided to Members, regardless of whether (i) a Pre-Authorization was
          obtained, or (ii) the Provider is a Participating or Non-Participating
          Provider, as required under applicable state and federal law. VISTA
          shall not deny payment for Emergency Services based on the Member's
          failure to notify VISTA in advance of seeking treatment or within a
          certain period of time after the Emergency Services were rendered.
          VISTA shall pay for the screening, evaluation and examination that are
          reasonably calculated to assist the Provider in arriving at the
          determination as to whether the Member's condition is an Emergency
          Medical Condition. If a determination is made that an Emergency
          Medical Condition does not exist, payment for services rendered
          subsequent to that determination shall be governed by this Agreement.
          The determination as to whether an Emergency Medical Condition exists
          shall be made by a physician of the hospital or, to the extent
          permitted by applicable law, by other appropriate licensed
          professional hospital personnel under the supervision of the hospital
          physician.

     6.5  TERMINATION ON PCP'S DEATH OR DISABILITY. VISTA shall have the right
          to terminate this Agreement immediately upon PCP's death or disability
          where, as determined by VISTA in VISTA's sole judgment and discretion,
          PCP is unable to perform his or her duties and obligations as required
          under this Agreement.

     6.6  OIR CANCELLATION OF AGREEMENT AND NOTICE TO OIR AND AHCA. This
          Agreement shall be canceled immediately upon issuance of an order by
          OIR pursuant to Section 641.234 of the Florida Statutes. Further, in
          the event that either VISTA terminates this Agreement without cause
          under Section 6.2 hereof or PCP terminates this Agreement for any
          reason whatsoever, the party so terminating this Agreement shall
          provide OIR and AHCA, as required by applicable law, with sixty (60)
          days advance written notice of such termination, or such longer time
          as required by law; provided, however, that if VISTA terminates this
          Agreement for any other reason, VISTA shall immediately provide OIR
          and AHCA notice of such termination, as required by applicable law.

     6.7  CONTINUING CARE RESPONSIBILITIES. Except as otherwise provided in this
          Agreement, upon termination of this Agreement for any reason
          whatsoever, the rights of each party shall terminate; provided,
          however, that such termination shall not release PCP from: (i) PCP's
          agreement not to seek compensation from Members, other than as
          specifically permitted by Section 2.7, for Covered Services provided
          by PCP to Members prior to the effective date of termination of this
          Agreement, which agreement shall also be applicable after termination
          of this Agreement with respect to Covered Services provided to Members
          during any period in which PCP is providing continuing care to a
          Member as contemplated below; and (ii) PCP's obligation, under
          applicable law, to arrange and provide continuation of coverage and
          care for those Members then utilizing PCP as their Primary Care
          Physician or for whom treatment is otherwise active with PCP until the
          earlier of: (a) the completion of treatment of a condition for which
          the Member is receiving care on the effective date of termination; (b)
          the date on which the transfer of such Member's care to another
          Primary Care Physician can be arranged by VISTA; or (c) the next open
          enrollment period offered by the Subscriber Group, if applicable;
          provided, however, that PCP shall not be required to provide such
          continuation of coverage and care to any Member longer than six (6)
          months after the effective date of termination of this Agreement.
          Notwithstanding the foregoing, VISTA shall allow PCP and PCP shall
          continue to provide care after the termination of this Agreement for
          any Member who initiated a course of prenatal care, regardless of the
          trimester in which care was initiated, until completion of postpartum
          care. Notwithstanding anything herein to the contrary, if termination
          of this Agreement occurs during the insolvency of VISTA or in the
          event that the contract between CMS and VISTA terminates or is not
          renewed for any reason whatsoever, PCP shall provide Primary Care
          Services to Members for the duration of the later of: (i) the period
          for which the Member made payment under his/her VISTA Coverage Plan or
          for the duration of the contract period for which CMS payments were
          made to VISTA on behalf of the Member, as

          applicable; (ii) the duration of any stay by the Member in an
          inpatient facility on the date of insolvency or, in the event that the
          contract between CMS and VISTA expires or terminates, until the Member
          is discharged from such facility; or (iii) such longer period of time
          as may be necessary for VISTA to remain in compliance with federal and
          state laws and regulations, including, without limitation, Medicare
          and Medicaid. During any such continuation of care period, VISTA shall
          compensate PCP in accordance with Schedule 4.1 of this Agreement for
          care rendered to any Member and PCP shall be bound by the terms of
          this Agreement. PCP further agrees that (i) this Section 6.7 shall
          survive the termination of this Agreement regardless of the cause
          giving rise to termination and shall be construed to be for the
          benefit of the Member; and (ii) this Section 6.7 supersedes any oral
          or written agreement to the contrary, whether now existing or
          hereafter entered into between PCP and a Member, or persons acting on
          a Member's behalf.

     6.8  NOTIFICATION BY PCP TO VISTA. Upon termination of this Agreement for
          any reason whatsoever (including expiration of this Agreement without
          renewal), PCP shall notify VISTA in writing:

          6.8.1 of the reason for PCP's termination of this Agreement; and

          6.8.2 within fifteen (15) days of termination of this Agreement of (i)
                a detailed list, in such format as required under VISTA
                Policies, of all Members receiving Primary Care Services at the
                time of termination of this Agreement who require continuation
                of care in any capacity whatsoever with the Member's name,
                address, phone number, identification number, type of service
                required or equipment in use, frequency of such service and
                ordering physician's name and phone number; and (ii) copies of
                all medical records and treatment plans related to Members being
                transitioned, in accordance with applicable law at no cost to
                VISTA. In the event PCP fails to comply with this Section 6.8.2,
                VISTA may withhold any and all payment due by VISTA to PCP until
                such time as VISTA receives the requested information.

     6.9  NOTIFICATION BY VISTA TO PCP. In the event VISTA terminates this
          Agreement for any reason whatsoever or suspends PCP pursuant to
          Section 2.12, VISTA shall provide PCP with written notice of the:

          6.9.1 reasons for the action, including, if relevant, the standards
                and profiling data used to evaluate PCP and the numbers and mix
                of Primary Care Physicians needed by VISTA; and

          6.9.2 with respect to Medicare Members only, PCP's right to appeal the
                action and the process and timing requirements for requesting a
                hearing.

     6.10 NONPAYMENT. PCP acknowledges and agrees that nonpayment for goods or
          services rendered by PCP to Members shall not be a valid reason for
          avoiding the sixty (60)

          with respect to all Participating Providers or solely with respect to
          PCP, at VISTA's sole discretion, upon notice to PCP in accordance with
          this Agreement; provided, however, that termination of this Agreement
          with respect to a particular Benefit Program(s) shall have no effect
          on the continuation of this Agreement with respect to all other
          Benefit Programs as listed on Schedule D. As such, this Agreement
          shall remain in full force and effect with respect to any Benefit

          to any compensation not expressly provided for herein.

     6.13 COOPERATION UPON TERMINATION. Upon termination of this Agreement for
          any reason whatsoever, the parties shall cooperate with each other to
          ensure compliance with this Agreement and the parties' continuing
          obligations as required under this Agreement, including but not
          limited to obligations of the parties set forth in Section 6.7 hereof.

7    RECORDS. PCP shall maintain, provide and allow access to records as set
     forth on Schedule 7, attached hereto and incorporated herein, and otherwise
     set forth in VISTA Policies and applicable laws and regulations. In the

     as PCP complies with VISTA's request.

     9.1  CONFIDENTIALITY.

          9.1.1 CONFIDENTIAL MATERIALS. PCP acknowledges and agrees that as a
                result of this Agreement, PCP may become informed of, and have
                access to, valuable and confidential information of VISTA and
                VISTA Affiliates, including, without limitation, (i) eligibility
                lists and any other information containing the names, addresses
                and telephone numbers of Members; (ii) VISTA Policies and all
                forms related thereto; (iii) other policy and procedure manuals;
                (iv) the provisions of this Agreement, including but not limited
                to reimbursement provisions set forth herein; and (v) any other
                information compiled or created by VISTA which is proprietary in
                nature, including names, payment rates and methodologies,
                business methods, trademarks, logos, patents and copyrights (the
                "Confidential Information"), and that the Confidential
                Information, even though it may be contributed, developed or
                acquired, in whole or in part, by PCP, shall remain the
                exclusive property of

PCP

                                       15



                VISTA to be held by PCP in trust and solely for VISTA's benefit.
                Accordingly, except as required by law or expressly authorized
                under this Agreement, PCP shall not, at any time, either during
                or subsequent to the Term, use, reveal, report, publish, copy,
                transcribe, transfer or otherwise disclose to any person,
                corporation or other entity, any of the Confidential Information
                without the prior written consent of VISTA, except to
                responsible persons who are in a contractual or fiduciary
                relationship with VISTA and for information which legally and
                legitimately is or becomes of general public knowledge from
                authorized sources other than PCP or any person acting on PCP's
                behalf.

          9.1.2 RETURN OF CONFIDENTIAL INFORMATION. Upon termination of this
                Agreement to the extent permitted by applicable law, PCP shall
                promptly deliver to VISTA all Confidential Information that is
                in PCP's possession or control, including all copies and
                abstracts of Confidential Information.

          9.1.3 CONFIDENTIAL OPERATIONS INFORMATION. Unless otherwise required
                by law, PCP shall not disclose information relating to the
                operations of VISTA or VISTA Affiliates to third parties without
                obtaining VISTA's prior written consent.

          9.1.4 CONFIDENTIALITY OF MEMBERS' INFORMATION. PCP shall protect the
                confidentiality of Members' information and records to the
                extent consistent with applicable law and shall comply with
                VISTA Policies on the release of information (whether written or
                oral) about Members and all applicable state and federal laws
                and regulations protecting the confidentiality of Members'
                records and disclosure of mental health records, medical records
                and other health and Member information, including, but not
                limited to, (i) all applicable requirements of the Health
                Insurance Portability and Accountability Act of 1996, Public Law
                104-191, as amended from time to time ("HIPAA"), and
                particularly Title II, Subtitle F (Administrative
                Simplification) thereof (42 U.S.C. Sections 1171 et. seq.) and
                (b) all applicable HIPAA regulations, as amended from time to
                time.

          9.1.5 OWNERSHIP. Ownership of and right of control over all
                Confidential Information shall vest exclusively in VISTA.

          9.1.6 NON-SOLICITATION OF MEMBERS. PCP recognizes and agrees that
                VISTA has a valuable business relationship with each of its
                Members and, further, that PCP stands in a position to influence
                Members' decisions concerning insurers. In recognition of
                VISTA's valuable business relationships with its Members, PCP
                agrees that, during the Term, and upon termination of this
                Agreement for any reason whatsoever, PCP shall not solicit
                Members, directly or indirectly, to enroll in any other health
                insurance or health coverage or alternative health care delivery
                system. PCP's obligation not to

PCP

                                       16



                solicit Members is a material inducement for PCP's engagement by
                VISTA pursuant to this Agreement. This Section 9.1.6, however,
                is not intended to interfere with a Member's right to freely
                select a Primary Care Physician or alternative health coverage
                subsequent to termination of this Agreement. Further, PCP
                acknowledges and agrees that any and all marketing or
                solicitation communication with Medicare Members and Medicaid
                Members must be approved in advance of dissemination by CMS or
                AHCA, as applicable, in accordance with applicable requirements.

          9.1.7 ENFORCEMENT. PCP acknowledges and agrees that irreparable injury
                will result to VISTA in the event of PCP's breach of these
                covenants, that a material inducement for PCP's engagement by
                VISTA are the covenants set forth in this Section 9.1, and that
                monetary damages in an action at law would not provide an
                adequate remedy in the event of a breach of this Section 9.1.
                PCP further acknowledges and agrees that the covenants set forth
                in this Section 9.1 are necessary for the protection of VISTA's
                legitimate business and professional duties, ethical
                obligations, and interests and are reasonable in scope and
                content. Accordingly, in the event of PCP's breach of (i) this
                Section 9.1, or any part of this Section 9.1, this Section 9.1
                may be enforced by the obtaining of an injunction to restrain
                the violation thereof by PCP and all persons acting for or with
                PCP; or (ii) Section 9.1.6, as determined by a court of
                competent jurisdiction, PCP shall pay to VISTA and amount equal
                to one thousand two hundred dollars ($1,200) for each Member PCP
                inappropriately solicits, directly or indirectly, to enroll in
                any other health insurance or health coverage or alternative
                health care delivery system in violation of Section 9.1.6, in
                addition to all other remedies VISTA may have at law or in
                equity.

     9.2  ASSIGNMENT. PCP shall not assign, delegate, subcontract, or otherwise
          transfer its rights, obligations and/or interests arising under this
          Agreement, including, but not limited to a transfer resulting from
          either an asset or stock purchase, without the express written consent
          of VISTA. VISTA may assign, delegate, subcontract or otherwise
          transfer its rights, obligations and/or interests under this Agreement
          to any successor, VISTA Affiliate or a party to which any of VISTA's
          line(s) of business are sold, assigned or otherwise transferred,
          without PCP's consent. This Agreement shall be binding upon and inure
          to the benefit of the successors and permitted assigns of the parties.

     9.3  SEVERABILITY. In the event that one or more provisions of this
          Agreement are determined to be invalid, illegal or unenforceable, in
          whole or in part, the validity, legality and enforceability of the
          remaining terms of this Agreement shall not in any way be affected.

     9.4  ATTORNEYS' FEES. In the event of any action, dispute, litigation or
          other proceeding with respect to this Agreement or any specific term
          of this Agreement, the prevailing

PCP

                                       17



          party in such action, dispute, litigation or other proceeding shall be
          entitled to recover reasonable fees, costs and expenses of counsel
          incurred in connection with such proceeding, whether suit is
          instituted or not, and if instituted, at both trial and appellate
          levels, in addition to any and all other relief to which it may
          otherwise be entitled at law or in equity.

     9.5  MODIFICATIONS. VISTA may modify or amend one or more provisions of
          this Agreement, including, but not limited to the addition of a new
          Benefit Program, upon thirty (30) days notice to PCP. The failure of
          PCP to object to such modification in writing to the Executive Vice
          President of Provider Operations during the thirty (30) day notice
          period shall constitute acceptance of such amendment or modification
          as of the effective date set forth in the notice. If PCP objects to
          such modification or amendment, VISTA may terminate this Agreement
          upon its giving sixty (60) days prior notice to PCP, or on such other
          date as is set forth in the notice to PCP; provided, further, that
          this Agreement shall automatically be modified or amended without
          notice or PCP's ability to reject such modification or amendment, to
          the extent necessary from time to time to comply with the requirements
          of state or federal laws or regulations or to comply with the
          requirements or regulations of any Accreditation Organization, AHCA,
          CMS, OIR, any other governmental agency with jurisdiction over VISTA
          or PCP, or the requirements of any VISTA Coverage Plan.
          Notwithstanding the foregoing, any and all changes or modifications to
          this Agreement made within thirty (30) days prior to the effective
          date of termination of this Agreement shall be effective only if
          agreed to by the parties.

     9.6  INCORPORATION OF SCHEDULES. All schedules and exhibits to this
          Agreement are considered part of this Agreement and are fully
          incorporated in this Agreement with the same effect as if such
          schedules and exhibits were restated in their entirety in the body of
          this Agreement.

     9.7  GOVERNING LAW. This Agreement is made, delivered in and shall be

          regulations promulgated thereunder; and (vii) Sections 409.901 -
          409.920 of the Florida Statutes, and the regulations promulgated
          thereunder by AHCA. This Agreement is also subject to the applicable
          rules and regulations of AHCA, CMS and OIR. Any provisions required by
          any laws and regulations to be included in this Agreement shall be
          binding upon VISTA and PCP whether or not expressly included or
          referenced in this Agreement. Any and all references to specific laws
          or regulations

          in this Agreement shall include any successor laws or regulations and
          any and all amendments. The parties shall comply with all applicable
          federal, state and local laws, rules and regulations of all governing
          authorities over their respective businesses.

     9.8  NON-EXCLUSIVE. VISTA acknowledges and agrees that this Agreement in no
          way prohibits or restricts PCP from entering into a commercial
          contract with any other health maintenance organization. PCP
          acknowledges and agrees that this Agreement in no way prohibits or
          restricts VISTA or any VISTA Affiliate from entering into a commercial
          contract with any other health care provider, inside or outside of the
          Service Area.

     9.9  WAIVER. If any party decides not to terminate this Agreement, even
          though it has the right to do so in a particular instance, or delays
          its decision to terminate, such decision shall not be considered a
          waiver of its right to terminate on a future occasion for the same or
          any other reason, and any other waivers of the breach or violation of
          any provision of this Agreement shall not operate as, or be construed
          to be, a waiver of any subsequent breach of the same or another
          provision of this Agreement. To be effective, a waiver of any of PCP's
          obligations under this Agreement must be in writing and signed by an
          authorized representative of VISTA.

     9.10 INDEPENDENT CONTRACTORS.

          9.10.1 The relationship between VISTA and PCP is an independent
                 contractor relationship. The parties acknowledge and agree that
                 neither party has the authority to make any representation,
                 warranty or binding commitment on behalf of the other party,
                 except as expressly provided in this Agreement or as otherwise
                 agreed to in writing by the parties, and nothing contained in
                 this Agreement shall be deemed or construed to (i) create a
                 partnership or joint venture between the parties or any
                 affiliate, employee or agent of a party; or (ii) constitute any
                 party or employee, agent or associate of a party as an
                 employee, agent or associate of the other party. No party shall
                 represent to any third party that it is an employee of another
                 party. PCP shall be responsible and shall pay in a timely
                 manner, FICA and all other taxes relating to payments made by
                 VISTA to PCP in accordance with this Agreement.

          9.10.2 PCP acknowledges and agrees that VISTA shall have no
                 responsibility for PCP's license, income, FICA, unemployment or
                 any and all other taxes, fees or levies upon PCP. PCP shall and
                 hereby does indemnify and save harmless VISTA and VISTA
                 Affiliates and their respective directors, officers, employees,
                 representatives and affiliated and subsidiary companies from
                 and against all liability for the same.

     9.11 CONSTRUCTION; ACKNOWLEDGMENT. All parties have participated in the
          negotiation of

PCP
October 4, 2004

                                       19



          this Agreement and, accordingly, the parties agree that this Agreement
          shall be construed and interpreted without regard to any presumption
          or other rule requiring construction against the party causing this
          Agreement to be drafted. PCP read this Agreement in its entirety,
          understands its contents, and had the advice of counsel as to this
          Agreement's meaning and intent.

     9.12 PROVIDER-PATIENT RELATIONSHIP. The parties acknowledge and agree that
          any and all decisions rendered by VISTA in its administration of this
          Agreement, including, but not limited to, all decisions with respect
          to the determination of whether or not a service is a Covered Service,
          are made solely to determine if payment of benefits under the
          applicable VISTA Coverage Plan is appropriate. The parties further
          acknowledge and agree that any and all decisions relating to the
          necessity of the provision or non-provision of medical services or
          supplies shall be made solely by the Member and PCP in accordance with
          the usual provider-patient relationship. PCP shall have sole
          responsibility for the medical care and treatment of Members under
          PCP's care. PCP further acknowledges and agrees that it is possible
          that a Member and PCP may determine that certain services or supplies
          are appropriate even though such services or supplies are not Covered
          Services under the applicable VISTA Coverage Plan and will not be paid
          for or arranged by VISTA. PCP shall inform Members in writing prior to
          provision of such non-Covered Services that such services are not
          Covered Services and that the Member will be responsible for payment
          for such non-Covered Services and collect the fees for such
          non-Covered Services directly from the Member.

     9.13 ANTI-GAG CLAUSE. Nothing contained in this Agreement is intended to
          interfere with the provider-patient relationship or to prohibit or
          otherwise restrict PCP from freely communicating with or advising or
          advocating on behalf of a Member regarding the Member's health status,
          medical care or treatment options, including any alternative
          treatments that may be self-administered, medication treatment options
          and any other medical care and treatment options for the Member which
          PCP deems knowledge of such information to be in the Member's best
          interest, regardless of benefit coverage limitations, including PCP's
          provision of sufficient information to the individual to provide an
          opportunity to decide among all relevant treatment options; the risks,
          benefits and consequences of treatment or non-treatment; or the
          opportunity for the individual to refuse treatment and to express
          preferences about future treatment decisions.

     9.14 HEADINGS. The headings contained in this Agreement are merely for the
          purpose of convenience of reference only and do not in any way affect
          the meaning or interpretation of this Agreement.

     9.15 ENTIRE AGREEMENT. Except as otherwise provided herein, this Agreement
          and all schedules and exhibits constitute the entire agreement and
          understanding between the parties relating to the subject matter of
          this Agreement and supersede all prior agreements between the parties,

          previously entered into a Primary Care Provider Services Agreement or
          any similar agreement with VISTA and/or a VISTA Affiliate relating to
          the subject matter of this Agreement or the provision of Primary Care
          Services that has not expired or been otherwise terminated, such
          agreement shall be deemed to have been superseded by this Agreement as
          of the Effective Date.

     9.16 COUNTERPARTS. This Agreement may be executed in multiple counterparts,
          each of which shall be deemed an original and all of which together
          shall constitute a single agreement.

     9.17 JURISDICTION; VENUE; INCONVENIENT FORUM; JURY TRIAL. Any suit, action
          or proceeding with respect to this Agreement shall be brought in
          federal or state court located in Broward County, Florida and the
          parties accept the exclusive personal jurisdiction of those courts for
          the purpose of any suit, action or proceeding. THE PARTIES KNOWINGLY,

          OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT AND ANY
          AGREEMENT CONTEMPLATED TO BE EXECUTED IN CONJUNCTION WITH THIS
          AGREEMENT OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS
          (WHETHER ORAL OR WRITTEN) OR ACTION OF ANY PARTY. THIS PROVISION IS A
          MATERIAL INDUCEMENT FOR THE PARTIES TO ENTER INTO THIS AGREEMENT.

     9.18 INTERPRETATION OF CERTAIN TERMS. When the context of this Agreement
          requires, the gender of all words shall include the masculine,
          feminine and neuter, and the number of all words shall include the
          singular and plural. All references herein to "Member" shall be deemed
          only to refer and apply to VHP Members, VIP Members, Medicare Members,
          Medicaid Members or Participants, as applicable to (i) the particular
          context of the Agreement; and (ii) those certain Benefit Programs
          listed on Schedule D hereof.

     9.19 CUMULATIVE REMEDIES. Except as otherwise provided for to the contrary
          in this Agreement, remedies provided for in this Agreement shall be in
          addition to and not in lieu of any other remedies available to any
          party and shall not be deemed a waiver or substitution for any action
          or remedy the parties may have at law or in equity. Pursuit of a
          particular remedy by a party shall not be deemed to constitute a
          waiver of any other right or remedy such party may have at law or in
          equity.

     9.20 SUBCONTRACTS. Except as otherwise permitted in this Agreement, PCP
          shall not delegate or subcontract any of its obligations under this
          Agreement without the prior written consent of VISTA. If PCP, with
          VISTA's consent, carries out any of its obligations or duties under
          this Agreement through a subcontract, such subcontract shall contain a
          clause which requires the subcontractor to comply with any and all

PCP

                                       21



          obligations and duties imposed on PCP in this Agreement, including
          Medicare and Medicaid laws and regulations. Such subcontract shall
          provide that the performance of the parties is monitored by VISTA on
          an ongoing basis and that VISTA may take enforcement actions in the
          event such subcontractor fails to comply, in VISTA's determination,
          with any obligation or duty imposed on PCP in this Agreement,
          including the Medicare and Medicaid laws and regulations.

     9.21 FORCE MAJEURE. No party to this Agreement shall be liable for any
          default or delay in the performance of its obligations hereunder if
          and to the extent the default or delay is caused, directly or
          indirectly, by strikes, picketing, insurrection, acts of God, military
          actions, terrorist attacks, war, emergencies, shortages or
          unavailability of materials or other causes beyond a party's
          reasonable control (a "Force Majeure Event"), and such party shall be
          excused from performance and shall not be considered to be in default
          hereunder in respect to the affected obligation. The suspension of
          performance due to a Force Majeure Event shall be of no greater scope
          and no longer duration than that which is reasonably necessary. The
          excused party shall use its reasonable best efforts to remedy its
          inability to perform as soon as possible.

     9.22 NO THIRD PARTY BENEFICIARY. Except as otherwise expressly provided
          herein, nothing in this Agreement is intended to, or shall be deemed
          or construed to create any rights or remedies in any third party,
          including but not limited to a Member.

     9.23 PARTICIPATION IN BENEFIT PROGRAMS. PCP acknowledges and agrees that,
          notwithstanding of the listing of a Benefit Program on Schedule D,
          PCP's participation in any one or more Benefit Program(s) is under no
          circumstances whatsoever conditioned by VISTA or a VISTA Affiliate or
          dependent on PCP's participation or non-participation in any other
          Benefit Program, relationship, arrangement, contract, line of business
          or other agreement with VISTA or any VISTA Affiliate.

     9.24 NO JOINT AND SEVERAL LIABILITY. Each of VHP, VIP and any Payor shall
          be severally liable for its own actions or inactions arising under,
          relating to or resulting from this Agreement. There shall be no joint
          liability between or among any of VHP, VIP or any Payor.

     9.25 EXECUTION BY AUTHORIZED REPRESENTATIVES. An authorized representative
          of each party shall execute this Agreement and an authorized
          representative of a party shall execute any and all notices given by
          such party hereunder. PCP represents and warrants that the individual
          executing this Agreement is authorized to bind PCP and all PCP Staff
          to the rights, obligations, conditions and terms set forth in this
          Agreement.

ADVERSE OR UNTOWARD INCIDENT - an event, as defined in Chapter 395.0197(5) of
the Florida Statutes, over which PCP could exercise control which is more

     B.   brain or spinal damage;

     C.   permanent disfigurement;

     D.   fracture or dislocation of bones or joints;

          intervention resulting from non-emergency medical intervention, other
          than an Emergency Medical Condition, to which the Member has not given

     G.   any condition that required the transfer of the Member, within or
          outside the facility, to a unit providing a more acute level of care
          due to the Adverse Incident, rather than the Member's condition prior
          to the Adverse Incident, including:

          1.   the performance of a surgical procedure on the wrong patient, a
               wrong surgical procedure or wrong-site surgical procedure, or a
               surgical procedure otherwise unrelated to the Member's diagnosis
               or medical condition;

          2.   required surgical repair of damage resulting to a Member from a
               planned surgical procedure where the damage was not a recognized
               specific risk, as disclosed to the Member and documented through
               the informed-consent process;

          3.   a procedure to remove unplanned foreign objects remaining from a
               surgical procedure; or

                                  SCHEDULE 2.19
                              MEDICAID REQUIREMENTS

      As required by applicable Medicaid laws and regulations, this Schedule
2.19 shall modify this Agreement to meet Medicaid requirements as determined by
the Medicaid HMO Model Contract ("Model Contract") between VISTA and/or a VISTA
Affiliate, as applicable ("VISTA") and the Florida Agency for Health Care
Administration, ("AHCA"). In case of any conflict between the terms of this
Agreement and this Schedule 2.19, the terms and provisions of this Schedule 2.19
shall prevail.

I.    VISTA'S RESPONSIBILITY TOWARDS AHCA.

      VISTA is responsible for all work performed under the Model Contract
      between AHCA and VISTA. In accordance with the Model Contract and subject
      to written approval by AHCA, VISTA is entering into a subcontract with
      PCP. The subcontract is the combination of this Agreement and this
      modifying Schedule 2.19. The parties shall comply with 42 C.F.R. 438.230
      and 42 C.F.R. 438.214. PCP shall comply with any and all requirements
      imposed on VISTA and/or PCP as a subcontractor of VISTA as set forth in
      the Model Contract.

      This Agreement and this Schedule 2.19 shall not in any way relieve VISTA
      of any responsibility for the performance of its duties under the Model
      Contract. All tasks related to this Agreement and this Schedule 2.19 shall
      be performed in accordance with the Model Contract.

      VISTA shall not discriminate with respect to participation, reimbursement,
      or indemnification as to any provider, including PCP, who is acting within
      the scope of the provider's license, or certification under applicable
      state law solely on the basis of such license or certification in
      accordance with Section 4704 of the Balanced Budget Act of 1997.

II.   CONDITIONS AND METHOD OF PAYMENT.

      A.    THIRD PARTY RESOURCES COLLECTION.

            VISTA assumes full responsibility for third party collections. If
            third party liability exists, payment of claims shall be determined
            in accordance with section 70.20 of the Model Contract (Third Party
            Resources).

      B.    SUBMISSION OF PAYMENT INFORMATION.

            PCP shall submit all information necessary for payment of claims in
            accordance with the Agreement.

                                       43



      C.    METHOD AND AMOUNT OF COMPENSATION.

            VISTA shall compensate PCP in accordance with this Agreement,
            641.3155, F.S., 42 C.F.R. 447.46, 42 C.F.R. 447.45(d)(2), (3), (5)
            and (6). Upon AHCA's request, VISTA shall make disclosure of the
            method and amount of compensation or other consideration to be
            received from VISTA. PCP shall not charge for any service provided
            to Medicaid Members at a rate in excess of the rates established by
            this Agreement in accordance to Section 1128B(d)(1), Social Security
            Act (enacted by Section 4704 of the Balanced Budget Act of 1997). If
            this Agreement contains provisions for charging the Medicaid Member
            co-payments, cost sharing, or for missed appointments, this Schedule
            2.19 renders such provisions null and void as the same pertain to
            Medicaid Members.

      D.    PHYSICIAN INCENTIVE PLANS.

            If VISTA uses a Physician Incentive Plan ("PIP"), the PIP shall
            comply with 42 C.F.R. 417.479, 42 C.F.R. 438.6(h), 42 C.F.R. 422.208
            and 42 C.F.R. 422.210. VISTA shall make no specific payment directly
            or indirectly under a PIP to PCP as an inducement to reduce or limit
            Medically Necessary services furnished to a Medicaid Member. The PIP
            shall not contain provisions that provide incentives, monetary or
            otherwise, for the withholding of Medically Necessary care. VISTA
            shall disclose to CMS information on PIPs in accordance with 42
            C.F.R. 417.479(h)(1) and 417.479(I) and at the times indicated in 42
            C.F.R. 417.479(d) - (g). VISTA shall submit all such information to
            AHCA for approval, in writing, prior to use. If any other type of
            withhold arrangement currently exists, it must be omitted from all
            subcontracts.

      effective dates for authorizations, if appropriate; and (iii) written
      confirmation of adverse determinations to the provider and the Medicaid
      Member, as required under applicable law. In such instances where PCP with
      VISTA's approval delegates or subcontracts any such functions, such
      subcontract or delegation must include all the Medicaid requirements of
      this Agreement and this Schedule 2.19.

F.    ELIGIBILITY TO PARTICIPATE IN THE MEDICAID PROGRAM.

      PCP shall be eligible for participation in the Medicaid program and shall
      have a unique identifier in accordance with the system established under
      Section 1173(b) of the Social Security Act.

G.    REVOCATION OF DELEGATED FUNCTIONS.

      VISTA shall have the right to revoke any function delegated to PCP under
      this Agreement and/or impose any sanctions VISTA deems appropriate in the
      event VISTA or AHCA determines PCP's performance under this Agreement to
      be inadequate.

      This Schedule 2.23 shall apply to Network Access Arrangements and shall
supplement and modify this Agreement with respect to Participants. In case of
any conflict between the terms of this Agreement and this Schedule 2.23, the
terms and provisions of this Schedule 2.23 shall prevail with respect to
Participants only. All references to VISTA in this Agreement shall apply to the
applicable Payor, unless otherwise required by the applicable Network Access
Arrangement, VISTA Policies or to the extent required by applicable laws and
regulations.

I.    NETWORK ACCESS ARRANGEMENTS.

      VISTA offers Network Access Arrangements to Payors (i) in connection with
      the applicable Payor Agreement pursuant to which, among other things,
      Participants are entitled to Primary Care Services that are reimbursable
      to PCP by the Payor in such amounts as specifically set forth on Schedule
      4.1, Exhibit 7, attached hereto and incorporated herein; and (ii) pursuant
      to which each of VISTA and the applicable Payor assume certain
      responsibilities and obligations, as set forth in the applicable Network
      Access Arrangement.

II.   DUTIES OF PCP.

      A.    PROVISION OF PRIMARY CARE SERVICES.

            PCP shall provide Primary Care Services to Participants in
            accordance with the applicable Payor Agreement and this Agreement.

      B.    BILLING AND COLLECTION.

            PCP shall be entitled to bill and collect from the applicable Payor
            and/or Participants, as required under the applicable Payor
            Agreement or as otherwise set forth in VISTA Policies, charges for
            all services provided to a Participant, including but not limited to
            Covered Services, including Primary Care Services, in accordance
            with and subject to the applicable Payor Agreement, Schedule 4.1 and
            Exhibit 7 thereof, this Schedule 2.23 and VISTA Policies. PCP
            acknowledges and agrees that VISTA in no way guarantees or is liable
            for (i) payment for any services rendered by PCP to Participants,
            including, but not limited to Covered Services or (ii) timeliness of
            payment for services rendered by PCP to Participants.

III.  CLAIMS PAYMENT.

      A.    LIABILITY FOR CLAIMS PAYMENT.

            1.    PAYOR; PARTICIPANT LIABILITY. PCP acknowledges and agrees that
                  either the applicable Payor and/or Participant, as applicable,
                  shall be liable for the payment of all claims for all
                  services, including Covered Services, rendered

PCP

                                       52



                  by PCP to Participant, in accordance with the applicable Payor
                  Agreement.

            2.    NO VISTA LIABILITY. PCP acknowledges and agrees that VISTA
                  shall not be liable for payment of any claims for any
                  services, including Covered Services, rendered by PCP to
                  Participants. PCP further acknowledges and agrees that under
                  no circumstances whatsoever shall VISTA be an insurer,
                  guarantor, or underwriter of the responsibility or liability
                  of a Payor or Participants to pay for services rendered by PCP
                  to Participants, including Covered Services.

      B.    REPRESENTATION AND WARRANTY. PCP hereby represents and warrants that
            the compensation amounts set forth in Schedule 4.1, Exhibit 7 hereof
            ("Compensation") are, in fact, true discount prices compared to
            PCP's Billed Charges for the same services. PCP acknowledges and
            agrees that irreparable injury will result to VISTA in the event of
            PCP's breach of this Schedule 2.23 and that a material inducement
            for PCP's engagement by VISTA are the covenants set forth in this
            Schedule 2.23. In the event PCP breaches this Schedule 2.23, VISTA
            shall have the right, in  addition to any other right or remedy
            VISTA may have under this Agreement or at law or in equity, to
            automatically terminate this Agreement.

IV.   INDEMNIFICATION.

      A.    PCP'S OBLIGATIONS. PCP shall indemnify, defend, and hold harmless,
            VISTA, VISTA Affiliates and their officers, directors, employees,
            affiliates, subsidiaries and agents from and against all expenses,
            claims, losses, damages, debts, obligations and other liabilities
            (or actions in respect thereof), including reasonable attorneys'
            fees and court costs incurred in the investigation, settlement or
            defense of any such action, whether threatened or actual, at trial
            level or on appeal, arising out of or resulting from the acts or
            omissions of PCP or its officers, employees or agents occurring
            during or in connection with the performance of or failure to
            perform any of PCP's obligations under this Agreement or this
            Schedule 2.23 and the  provision of or failure to provide any and
            all services by PCP to Participants in accordance with this
            Agreement.

      B.    PAYORS' OBLIGATIONS. PCP acknowledges and agrees that, with respect
            to Network Access Arrangements, Payor has certain responsibilities
            and obligations as set forth in the applicable Network Access
            Arrangement, Payor Agreement, this Agreement and applicable VISTA
            Policies. Based on the foregoing, PCP shall indemnify, defend, and
            hold harmless, VISTA, VISTA Affiliates and their officers,
            directors, employees, affiliates, subsidiaries and agents from and
            against all expenses, claims, losses, damages, debts, obligations
            and other liabilities (or actions in respect thereof), including
            reasonable attorneys' fees and court costs incurred in the
            investigation, settlement or defense of any such action, whether

            of or failure to perform any of Payor's responsibilities or
            obligations under the applicable Network Access Arrangement, Payor

V.    SILENT PPO.

      The parties acknowledge and agree that this Agreement is intended to apply
      to legitimately directed business through Payors' participation in a
      Network Access Arrangement. VISTA agrees not to make available, directly
      or indirectly, the Compensation to individuals who are not Participants at
      the time PCP renders Primary Care Services to such individuals.

                                  SCHEDULE 4.1
                                  COMPENSATION

I.    COMPENSATION FOR CAPITATED SERVICES.

      A.    CAPITATION FEE. For each Member selecting or assigned to PCP, VISTA
            shall pay to PCP on a monthly basis the applicable Capitation Fee,
            as set forth in the applicable Exhibit(s) to this Schedule 4.1. This
            Capitation Fee shall serve as payment for all Primary Care Services
            set forth in Schedule C, except as otherwise set forth in the
            applicable Exhibit(s) to this Schedule 4.1 ("Capitated Services"),
            subject to adjustment in accordance with this Agreement. Such
            payments shall be made by VISTA to PCP on or before the fifteenth
            (15th) day of each month and shall constitute payment in full for
            all Capitated Services and obligations provided by PCP under this
            Agreement, except applicable Co-Payments, Deductibles and
            Co-Insurance amounts.

      B.    DEDUCTIONS FROM CAPITATION FEE. If PCP Refers a Member to a Provider
            in a manner inconsistent with VISTA Policies, the cost of any
            services provided by such Provider shall, at VISTA's discretion, be
            the financial responsibility of PCP, and VISTA may deduct such
            amount from any and all payment otherwise due PCP from VISTA,
            including the Capitation Fee.

      C.    CAPITATION FEE ADJUSTMENTS. If, in VISTA's determination, a Member
            should have been included on PCP's Member list and was not so
            included, VISTA shall retroactively add such Member to PCP's panel
            for a period of up to ninety (90) days from the date VISTA
            determines that the particular Member should have been included in
            PCP's panel and PCP shall receive applicable Capitation Fee payments
            on behalf of that Member for such period. If, in VISTA's
            determination, a Member was erroneously or inappropriately placed on
            PCP's panel or is retroactively terminated, VISTA shall offset any
            Capitation Fee payment previously paid to PCP on behalf of such
            Member for a period of up to one (1) year from any and all payments
            otherwise due PCP, including the Capitation Fee; provided, however,
            that such one (1) year limitation shall not apply to Members covered
            under Federal Employee Health Benefit Program, Medicare or Medicaid
            pursuant to an adjustment made by CMS or AHCA, as applicable.

      D.    PRORATION OF CAPITATION FEE UPON TERMINATION. PCP acknowledges and
            agrees that if the effective date of termination of this Agreement
            occurs on any day other than the first (1st) day of a month, the
            Capitation Fee shall be prorated to account for only those days that
            this Agreement was in effect during the applicable month in which
            the termination is effective.

      E.    PAYMENT UPON TERMINATION FOR CONTINUATION OF CARE SERVICES. Upon
            termination of this Agreement for any reason whatsoever, as required
            under applicable law and regulations and in accordance with Section
            6.7 hereof, VISTA shall pay PCP and PCP shall accept as payment in
            full for all Capitated Services

PCP

                                       55



            rendered by PCP to Members for continuation of care and treatment as
            required under Section 6.7 an amount equal to the Capitation Fee for
            each such Member PCP is providing continuation of care and treatment
            for each month PCP is required to provide such services as set forth
            in Section 6.7, in accordance with this Schedule 4.1.

II.   COMPENSATION FOR NON-CAPITATED PRIMARY CARE SERVICES.

      A.    PAYMENT OF CLAIMS; TIMELY SUBMISSION OF CLAIMS. VISTA shall
            compensate PCP as set forth in this Schedule 4.1 for non-Capitated
            Services set forth in the applicable Exhibit(s) to this Schedule 4.1
            ("Fee For Services"). Fee For Services shall also include any and
            all claims for non-assigned Members not otherwise payable under this
            Schedule 4.1, Section I. VISTA shall pay all Clean Claims or any
            portion of a Clean Claim submitted by PCP to VISTA for Fee For
            Services furnished by PCP to Members in accordance with applicable
            state and federal law and regulations; provided; however, that VISTA
            shall have no obligation whatsoever to pay for any service(s)
            rendered by PCP to a Member if PCP fails to submit a Claim for such
            services in accordance with applicable state and federal law.

      B.    CLAIMS APPEALS. In the event VISTA denies a claim submitted by PCP
            to VISTA or PCP otherwise contests the accuracy of VISTA's payment
            for services rendered to a Member, PCP shall have sixty (60) days
            from the date of PCP's receipt of VISTA's denial or payment of such
            claim to file a written appeal with VISTA contesting such claim
            denial or the accuracy of the payment in accordance with VISTA
            Policies. If PCP fails to file an appeal with VISTA in accordance
            with VISTA Policies within such sixty (60) day period, PCP agrees
            that such claims shall be deemed uncontestable.

      C.    CLAIMS PAYMENT INFORMATION. PCP shall send any and all Claims to the
            applicable mailing or electronic address as set forth in Exhibit 8,
            attached hereto and incorporated herein, unless otherwise required
            by VISTA Policies or the applicable VISTA Coverage Plan. If PCP has
            any questions or concerns regarding Claims, PCP may call such
            numbers as indicated in Exhibit 8.

      D.    EXHAUSTION OF APPEALS PROCESS. PCP shall exhaust all remedies
            available to PCP under VISTA's internal dispute resolution process,
            as set forth in this Agreement and VISTA Policies, as a prerequisite
            to PCP's submission of a claim resolution pursuant to the state
            provider assistance program.

      E.    UP-CODING. PCP acknowledges and agrees that up-coding by PCP with
            the intent to obtain reimbursement from VISTA not otherwise due PCP
            is a false and fraudulent insurance claim punishable in accordance
            with Section 641.52(5) of the Florida Statutes.

      F.    DUPLICATE CLAIMS. PCP shall not submit a duplicate claim to VISTA
            for the same

PCP
October 4, 2004

                                       56



            services provided to the same Member on the same date of service
            unless it is determined that the original claim was not received or
            is otherwise lost.

      G.    RETROACTIVE ADJUSTMENTS. Any retroactive demands by PCP for payment
            due to underpayments or non-payments for Covered Services must be
            reconciled to specific Claims unless the parties agree to other
            reconciliation methods and terms.

      H.    FLORIDA MOTOR VEHICLE NO-FAULT LAW. PCP shall comply with the
            Florida Motor Vehicle No-Fault Law, Section 627.736, Florida
            Statutes (the "No-Fault Law"), by filing all Claims with the motor
            vehicle liability insurer for services provided by PCP to Members
            related to a Member's personal injuries which are covered under
            motor vehicle liability insurance within the required thirty (30) or
            sixty (60) day time period, as required under the No-Fault Law.
            VISTA shall have no obligation to pay any Claim for services
            provided by PCP to a Member that is denied by the motor vehicle
            liability insurer due to PCP's failure to comply with the
            requirement under the No-Fault Law for timely filing of claims.

      I.    CPT CODES. In submitting claims to VISTA, PCP shall use the most
            current procedural terminology ("CPT") codes on all required forms.
            PCP shall comply with all rules and guidelines governing use of CPT
            Codes, including, but not limited to inclusive CPT codes.

      J.    BILLED CHARGES. In the event PCP's Billed Charge for a service
            listed in any Exhibit hereto is changed by any amount whatsoever, in
            any manner whatsoever (the "New Billed Charge"), (i) PCP shall
            immediately notify VISTA; and (ii) this Agreement shall be
            automatically amended, without the need for PCP's consent, so that
            the compensation set forth herein is reduced to reflect the same
            percentage discount to the New Billed Charge for the particular
            service(s) as the compensation represents with respect to Billed
            Charge for such service(s). PCP acknowledges and agrees that
            irreparable injury will result to VISTA in the event of PCP's breach
            of this Schedule 4.1 and that a material inducement for PCP's
            engagement by VISTA are the covenants set forth in this Schedule
            4.1. In the event PCP breaches this Schedule 4.1, VISTA shall have
            the  right, in addition to any other right or remedy VISTA may have
            under this Agreement or at law or in equity, to automatically (i)
            terminate this Agreement and (ii) offset any and all payments
            otherwise due PCP from VISTA, including future compensation, in an
            amount equal to the difference between (1) compensation paid by
            VISTA to PCP where the compensation was based on the New Billed
            Charge which compensation did not equal the same percentage discount
            to the New Billed Charge for the particular service(s) as the
            compensation represented with respect to the Billed Charge for such
            service(s) and (2) compensation based on the New Billed Charge which
            is equal to the same percentage discount to the Billed Charge for
            the particular service.

III.  PAYMENTS TO VISTA.

      A.    OVERPAYMENTS. In the event VISTA determines, as a result of
            retroactive review of coverage decisions or payment levels or
            otherwise, it made an overpayment to PCP for services rendered to a
            Member, VISTA shall make a claim to PCP for such overpayment in
            accordance with applicable state and federal laws and regulations.
            PCP shall pay a claim for overpayment submitted by VISTA to PCP in
            accordance with applicable state and federal laws and regulations.

      B.    OFFSET. PCP acknowledges and agrees that VISTA may reduce payment to
            PCP in connection with a claim for overpayment at VISTA's discretion
            or in the event PCP fails to comply with Article III of this
            Schedule 4.1.

      C.    RECOVERY RIGHT. PCP acknowledges and agrees that VISTA shall have
            the right to recover any and all amounts due VISTA by PCP under this
            Agreement, as determined by VISTA in VISTA's sole discretion and in
            accordance with applicable laws and regulations.

      D.    RETROACTIVE ADJUSTMENTS. Any retroactive reductions of payments or
            demands for refund of previous overpayments that are due to
            retroactive review of coverage decisions or payment levels must be

      as required by the PIP Regulations (i) a description of the financial

      Coverage Plan; (iii) VISTA is the designated beneficiary for Members
      covered by the policy for incurred but unpaid benefits for the time frame
      for which Capitation Fee payments were received by PCP in the event PCP is
      insolvent or bankrupt; and (iv) the policy insurer will provide notice of
      termination or cancellation of the policy to VISTA.
