                  from each  facility  will be applied to the  Deductible  in an

      in its  Membership  Service  Agreements.  Such  report  shall  be  sent to
      Preferred Life at least  thirty-one (31) days before the Effective Date of
      the change so that Preferred Life may evaluate the need for any changes in
      this Reinsurance Agreement.

C.    The Plan shall report to Preferred Life any  investigation  or request for
      information of a material nature by a State Insurance Department regarding
      the  conduct of the Plan.  Such  report must be provided in writing by the
      Plan to Preferred Life within  thirty-one (31) days following the date the
      Plan receives  notice,  written or  otherwise,  of such  investigation  or
      request from the State Insurance Department.

D.    The Plan shall keep a record of the monthly  enrollment of Members covered
      by its Membership  Service  Agreements and the Eligible  Hospital Services
      and Eligible Medical Services  received by each Member while covered under
      this Reinsurance Agreement. Such record shall be kept during the time this
      Reinsurance Agreement is in effect and for a one (1) year period after its
      termination date.

E.    The Plan's books and  records,  to the extent  permitted by law,  shall be
      made  available to  Preferred  Life for  inspection  and audit at any time
      during normal business hours during the time this Reinsurance Agreement is
      in effect and for a one (1) year period after its termination date.

F.    All information  disclosed to Preferred Life by the Plan or to the Plan by
      Preferred Life, either in the course of conducting  negotiations or as the
      result of  complying  with the terms and  conditions  of this  Reinsurance
      Agreement,   shall  be  considered  to  be  privileged  and   confidential
      information by both the Plan and Preferred Life.

G.    The  submission  of  this  Reinsurance  Agreement  to  any  Department  of
      Insurance  or any  State or  Federal  agency  shall  not be  considered  a
      violation of F above."

                                   ARTICLE VI

                                   Arbitration

A.    In the event of any dispute or difference  of opinion  arising out of this
      Agreement  which  cannot be amicably  resolved  by the Plan and  Preferred
      Life, the Plan and Preferred Life agree that such dispute or difference of
      opinion shall be submitted to and settled by arbitration.

B.    Except as otherwise provided herein, the arbitration shall be conducted in
      accordance  with  the  Commercial   Arbitration   Rules  of  the  American
      Arbitration  Association  (the "AAA" and the "AAA's Rules") which shall be
      in effect on the date of delivery of demand for arbitration.  In the event
      that the AAA's Rules  conflict with any  provisions of this Article,  this
      Article shall govern.

C.    The party that determines that a dispute should be resolved by arbitration
      (the "Initiating Party") shall give written notice to the other party (the
      "Responding  Party") of its  desire to compel  arbitration,  which  notice
      shall  contain a statement  setting  forth the nature of the dispute,  the
      amount involved, if any, and the remedy sought.

D.    The  arbitration  tribunal shall consist of three  arbitrators who must be
      disinterested  parties,  unaffiliated with the Plan or Preferred Life. The
      Plan shall appoint one  arbitrator,  and Preferred  Life shall appoint one
      arbitrator.  The third  arbitrator  shall be appointed by the previous two
      (2) arbitrators.  If the two previous  arbitrators cannot agree on a third
      arbitrator, then the third arbitrator shall be appointed by AAA.

E.    If either party refuses or neglects to appoint an arbitrator  within sixty
      (60) days after receipt of written notice from the other party  requesting
      it to do so, the requesting  party shall instruct AAA to appoint a neutral
      second  arbitrator.  The two  appointed  arbitrators  can then appoint the
      third.

F.    For the  purposes of  arbitration,  this  Reinsurance  Agreement  shall be
      considered an honorable  engagement  rather than a mere legal  obligation,
      and the arbitrators  are not bound by judicial  formalities or strict rule
      of law in interpreting this Reinsurance Agreement.

G.    The decision of a majority of the  arbitrators  shall be final and binding
      on both the Plan and Preferred Life.

H.    The expense of arbitration shall be divided between the Plan and Preferred
      Life based on a decision made by the arbitrators.

I.    Any such  arbitration  shall  take  place in New York,  unless  some other
      location is mutually agreed upon.

J.    The laws of New York  shall  govern the  arbitration  process in the event

                                  ARTICLE VII

                       Insolvency/Cessation of Operations

A.    In the event that Preferred Life should become insolvent, this Reinsurance
      Agreement shall  automatically  terminate on the date of Preferred  Life's
      insolvency.

B.    In the  event  that the Plan  shall  become  insolvent,  this  Reinsurance
      Agreement  shall  automatically  terminate  on  the  date  of  the  Plan's
      insolvency.  All Reinsurance  shall be payable directly to the liquidator,
      receiver,  or statutory  successor of the Plan,  without diminution due to
      the insolvency of the Plan.

C.    For purposes of this  Reinsurance  Agreement,  "insolvent" or "insolvency"
      shall mean that both of the following conditions occur:

      1.    A final  determination is made by a court of competent  jurisdiction
            that the Plan or Preferred Life is insolvent; and

      2.    All operations of the Plan or Preferred Life cease.

            The date of  insolvency  shall be  determined  as the date which the
            court  declares the Plan or Preferred  Life insolvent or the date on
            which the Plan or Preferred  Life has ceased  operations,  whichever
            date is later in time.

            Operations of the Plan will not be considered  ceased so long as the
            Plan is in control of a Receiver (which, as used herein,  includes a
            court or state appointed  supervisor,  receiver,  or  rehabilitator)
            until  the date the  Receiver  stops  paying  for  future  services,
            publicly  declares  its  intention  to not make  payment  for future
            services,  and orders Plan providers to stop  rendering  services on
            behalf of the Plan other than those  services for the remaining term
            for which providers have previously been paid.

D.    In the event the Plan should cease  operations  and become  insolvent,  as
      defined  above,  during  the  term of this  Reinsurance  Agreement,  it is
      further agreed the following would apply:

      1.    The liquidator,  receiver,  or statutory successor of the Plan shall
            give written  notice to Preferred  Life of the pendency of any claim
            affecting this Reinsurance  Agreement within a reasonable time after
            such a claim is filed. During the pendency of such claim,  Preferred
            Life may  investigate at its own expense such claim and interpose in
            the proceeding  where such claim is to be adjudicated,  any defenses
            which  it may  deem  available  to the  Plan  or to its  liquidator,
            receiver, or statutory successor; and

      2.    The expense  thus  incurred by Preferred  Life shall be  chargeable,
            subject to court  approval,  against the Plan or its  successors  as
            part of the expense of liquidation to the extent of a  proportionate
            share of the benefit which

                                      -12-
<PAGE>

            may accrue to the Plan solely as a result of the defense  undertaken
            by Preferred Life.

E.    Notice of the Plan's or  Preferred  Life's date of  insolvency  or date of
      cessation of operations  shall be  communicated  to the other party at the
      earliest possible point in time.

                                  ARTICLE VIII

                       Limitations of Reinsurance Coverage

A.    Preferred Life's  reimbursement of claims to the Plan shall not exceed, in
      any event, the limits of coverage stated in Article II.

B.    The Plan is solely  responsible for providing all services to its Members,
      for  compensation of all liability to its Members,  and for payment of all
      expenses to its Members.

C.    Preferred Life shall have no  responsibility  or obligation to provide any
      services or payment to any Member of the Plan, directly or indirectly.

D.    To the extent the Plan  receives or will receive any payment or receives a
      reduction  in its  liability  by  reason  of a  Coordination  of  Benefits
      provision in the Plan's  Membership  Service  Agreement or by any right of
      subrogation,  Preferred  Life shall only  indemnify the Plan in respect of
      any excess  beyond the amount of COB or  subrogation  amounts  received or
      applied currently or in the future as reductions in its liability.

E.    Preferred  Life shall not  reimburse  the Plan for  amounts  incurred  for
      skilled nursing or rehabilitative services (including,  but not limited to
      treatments   for  motor   function  or  mobility,   physical   therapy  or
      psychotherapies),  unless such services are provided  concurrent  with and
      incidental to Acute Care Services.

F.    Preferred  Life  shall not be liable to the Plan,  and the Plan shall hold
      harmless and indemnify Preferred Life, for any of the following:

      1.    Professional  liability  or  liability  for  any  act  or  omission,
            tortious or otherwise,  in connection with any services  rendered to
            any person or group of persons by the Plan or any group,  entity, or
            person employed by or affiliated in any manner with the Plan;

      2.    Liability assumed by the Plan in excess of Plan's Membership Service
            Agreements as identified in Article I of this Reinsurance Agreement,
            including  liability under any contract other than Plan's Membership
            Service Agreements;

      3.    Expenses  or losses to which the Plan has  released  any  persons or
            entity from its legal liability;

      4.    Liabilities which are non-pecuniary in nature (not having a monetary
            value);

      5.    Liabilities,   expenses,   or  losses   which  are  based  upon  any
            noncompliance or violation of any Federal or State statute, rule, or
            regulation by the Plan;

                                      -14-
<PAGE>

      6.    Additional  expenses or losses  resulting  from those services which
            are  billed in excess of the  usual and  customary  charges  for the
            locality where same were administered;

      7.    Losses which are paid or payable to Plan Members who are enrolled in
            Part A and/or  Part B of Title XVIII of the Social  Security  Act of
            1965 and any Amendments to it;

      8.    Any expenses to the extent the Plan  receives a reduction in charges
            because  of a  Coordination  of  Benefits  provision  in the  Plan's
            Membership Service Agreements or any right of subrogation;

      9.    Any liability due to war or act of war;

      10.   Any liability for replacement of equipment,  furniture,  or supplies
            which  are  not  Eligible  Hospital  Services  or  Eligible  Medical
            Services.

      11.   Any  liability  for any  property  damage  expenses  resulting  from
            negligence by any party which causes a failure of any equipment used
            in the treatment of a Member.

      Article II.

B.    This  Reinsurance  Agreement  shall  continue in effect from the Effective

      the Plan's insolvency or cessation of operations.

E.    This Reinsurance  Agreement can be terminated in accordance with paragraph
      A. of Article X.

F.    Termination of this  Reinsurance  Agreement shall not terminate the rights
      or  liabilities  of either the Plan or Preferred  Life arising  during any
      period when this Reinsurance Agreement was in force, provided that nothing
      herein  shall be  construed  to  extend  Preferred  Life's  liability  for
      reimbursements  under this Reinsurance  Agreement for any Loss paid by the
      Plan  which  was  incurred  on or after  the date of  termination  of this
      Reinsurance Agreement.

G.    The Plan and  Preferred  Life shall each have the right to terminate  this
      Reinsurance Agreement by giving the other party, and the State of New York

                        MDNY-IPA RECONCILIATION AGREEMENT

      AGREEMENT,  dated as of May __, 2000 (the "Agreement"),  by and among MDNY
Healthcare,  Inc, a New York corporation  ("MDNY"),  Island Practice Association
I.P.A.,  Inc.  (d/b/a "Island  Professional  Association,  I.P.A."),  a New York
corporation("IPA"), Catholic Healthcare Network of Long Island, Inc., a New York
not-for-profit   corporation  ("CHNLI"),  and  Long  Island  Physician  Holdings
Corporation, a New York corporation ("LIPH") (collectively, "the parties").

      WHEREAS,  MDNY  is  a  health  maintenance   organization,   certified  in
accordance with the provisions of Article 44 of the Public Health Law;

      WHEREAS,  all of the shares of MDNY are currently  owned by LIPH and CHNLI
and all of the shares of IPA are currently owned by LIPH;

      WHEREAS,  MDNY entered into an IPA  Participation  Agreement  with IPA, in
accordance  with the laws and  regulations of the State of New York and with the
approval of the Department of Health,  by which it contracts with IPA to arrange
for the  delivery or  provision of health  services by  individuals  licensed to
practice medicine and other health professions;

      WHEREAS,  the  IPA  Participation  Agreement  specified  that  MDNY  would
compensate  IPA for these  services  pursuant to a schedule  specifying  certain
capitation payments, calculated as a percentage of premium of the various health
plan products offered by MDNY;

      WHEREAS, MDNY met this obligation to the IPA by paying claims incurred, in
accordance with  applicable fee schedules,  subject to a  reconciliation  of the
amounts in accordance  with the capitation  payment amounts set forth in the IPA
Participation Agreement;

      WHEREAS, during 1997 and 1998, upon review of all claims incurred and paid
that  arose  during  the  relevant  time  periods,  it  was  calculated,  to the
satisfaction of the parties based upon audited financial reports, that MDNY paid
claims in excess of the  amount  set forth in the IPA  Participation  Agreement,
resulting in a liability by the IPA to repay MDNY approximately $6 million;

      WHEREAS, since that time, pursuant to the IPA Participation  Agreement and
the existing capitation payment schedule,  MDNY has not made the payments to the
IPA as are set forth in the IPA  Participation  Agreement during 1999 and it was
calculated,  to the  satisfaction  of the parties  based upon audited  financial
reports, that MDNY owes the IPA approximately $18,465,000;

<PAGE>

      WHEREAS,  the parties to this  Agreement have each concluded that it would
be  appropriate  to reconcile  the amounts owed by MDNY to the IPA against those
owed by the IPA to the MDNY, rather than maintaining two offsetting liabilities;

      NOW, THEREFORE, in consideration of the mutual promises and covenants made
by each party to the others, the parties hereby agree as follows:

      1.    The parties agree, based on the findings of the independent auditors
            who have examined the financial transaction and payments between the
            parties,  that the outstanding  liabilities between the MDNY and the
            IPA are approximately as set forth above.

      2.    The parties  further agree that it is in the best  interests of each
            party to reconcile the outstanding liabilities and credit the amount
            owed by IPA to MDNY to reduce the amount owed by MDNY to IPA.

      3.    The parties agree that,  notwithstanding  any prior agreement to the
            contrary,  including  but  not  limited  to  the  IPA  Participation
            Agreement,  the  reconciliation  of those  amounts  shall  result in
            eliminating any repayment obligation by IPA to repay MDNY any of the
            overpayments   made  by  MDNY  on  the  EPA's   behalf   during  the
            above-referenced  time  period and shall  reduce the amount  owed by
            MDNY to the IPA as of this date for the  relevant  time  periods  to
            $12,465,000.

                                       2

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