          subject to a Change of Control (as hereinafter defined), Manager shall

          pending Change of Control as early as practicable, but in any event no
          less than thirty (30) days prior to the effectiveness of such Change
          of Control. Upon receipt of the Transfer Notice, Renaissance may elect
          to terminate this Agreement effective one hundred and eighty (180)

          notice of such election within thirty (30) days after the receipt by
          Renaissance of the Transfer Notice from Manager. If Renaissance does
          not provide such notice of its election within such thirty (30) day
          period, Renaissance shall be deemed to have waived its right to
          terminate this Agreement pursuant to this Section 6.2.3. If Manager
          does not provide the Transfer Notice to Renaissance as required
          hereunder, in addition to any other rights and remedies that
          Renaissance may have at law or in equity, Renaissance shall have the
          right to terminate this Agreement any time after it receives actual
          knowledge thereof by providing written notice of such termination to
          Manager, with any such termination to take effect at the time stated
          by Renaissance in its notice. As used herein, a "Change of Control"
          shall mean the occurrence of either or both (i) the acquisition,
          whether by operation of law or otherwise and whether by one or more
          transactions, including, without limitation, by sale, transfer or
          exchange of stock, membership interests or other equity interest,
          merger, consolidation, reorganization or conversion, or by voting
          agreement or other agreement, directly or indirectly, of the power to
          direct or cause the direction of the management and policies of
          manager, including, without limitation, the direct or indirect
          acquisition of fifty percent (50%) or more of the equity interest of
          Manager, and (ii) the sale, transfer, pledge or exchange, directly or
          indirectly, of any of the ownership interest of Herb Fritch in
          Manager, including, without limitation, any agreement by which any
          person or entity other than Herb Fritch directly or indirectly
          acquires the right to control any of the voting or other rights
          associated with the ownership interest of Herb Fritch in Manager.

     6.2.4 Termination on Notice for Default. If either party defaults in the
          performance of any obligation under this Agreement, the other party
          shall provide written notice detailing such default. The defaulting
          party shall have thirty (30) days, or ten (10) days in the event of
          nonpayment of fees under Article V, following the giving of written
          notice of such default by the other party, to cure the default. At the
          conclusion of the cure period, the party giving such notice shall have
          the right to immediately terminate this Agreement, without limiting
          any other rights or remedies that would otherwise be available.

     6.2.5 Termination for Insolvency. If either Party becomes insolvent, or if
          any petition under bankruptcy or insolvency or for a reorganization or
          arrangement or other relief from creditors shall be filed by or
          against either Party, or if either Party shall make an assignment of
          all or substantially all of its assets for the benefit of its
          creditors or if a receiver, trustee, or similar officer or creditor's
          committee shall be appointed to take charge of any property of or to
          operate or wind up the affairs

                                       12
<PAGE>
          of either Party, then the other Party may by written notice
          immediately terminate this Agreement.

     6.2.6 Termination for Non-Performance. In the event that Manager does not
          meet Performance Standards, as defined in Exhibit 3.17, the corrective
          action plan and associated fee reductions shall take place, leading to
          possible termination by Renaissance at the end of the period, all as
          defined specifically in Exhibit 3.17.

     6.2.7 Termination for Change in Statute or Regulation. If there shall be a
          change in the Medicare or Medicaid Statutes, case laws, regulations or
          general instructions, the adoption of new legislation or a change in a
          third party reimbursement system, any of which materially and
          adversely affects the manner in which either party may perform or be
          compensated for its services under this Agreement, or Renaissance's
          ability to obtain reimbursement from Medicare or Medicaid or any other
          third party payor (a "Change Event"), the parties agree to negotiate
          in good faith to modify the terms of this Agreement to comply with the
          Change Event to approximate as closely as possible the economic
          position of the parties prior to the Change Event. If the parties
          cannot reach an agreement on such modification within thirty (30) days
          of the Change Event, either party may terminate this Agreement by
          written notice to the other party effective as of any future date
          specified in such notice, or such sooner date as may be required by
          the Change Event. Nothing in this Agreement shall be interpreted to
          require either party at any time to do anything that is illegal or
          contrary to statute.

          a formal plan for winding up of the relationship, return of documents,
          and general resolution of outstanding issues. A pay-out services
          agreement will be entered into between Manager and Renaissance, for an
          orderly transition and winding up. Under any termination condition,
          the parties shall prepare a financial accounting, one to the other,
          and shall negotiate a settlement, subject as necessary to true-up,
          that shall permit both parties to conduct business or winding up of
          business in an effective and fair manner.

          provided in this Agreement. In the event of a dispute or third party

          addition, each party has been privy to confidential business
          information about the other, and shall maintain such information as
          confidential, returning any materials of whatever nature that may
          pertain to such confidential business matters to the other.

     Agreement, the parties will fully cooperate in any and all matters relating

                        Performance Standards for Manager

A.   Manager shall at all times meet and comply with the following standards:

     1.   Clean claims based on statutory requirements shall be processed within
          45 days.

     2.   At least 95% of all clean claims shall be paid consistently and
          accurately.

     3.   Reinsurance will be timely filed, at least quarterly or within the
          stipulation of the reinsurance policy.

     4.   Physician capitation will be paid by and delivered to physicians by
          the 22nd calendar day of the month. All such payments shall be made in
          conjunction with the latest eligibility list provided by the payor.

     5.   Delegated functions, UM, credentialing, claims payment, shall be
          maintained in accordance with delegation requirements.

     6.   Financial statements including an income, balance sheet and cash flow
          statements will be produced monthly and provided to the Board. Other
          key reports such as utilization statistics and physician profiling
          will be mutually agreed to with the Board as to timing and content.

B.   If an event as defined in Section 8.9 (a Force Majeure) makes it impossible
     for Manager to meet these standards, it shall be the responsibility of
     Manager to notify Renaissance in writing, if possible under the
     circumstances, delivered personally or by overnight delivery service, and
     to keep Renaissance informed of all actions being taken to bring the matter
     under Manager's control. In such case, the penalty of ten (10) percent of
     Management Fee shall not be retained by Renaissance.

C.   C. If Manager, due to its own performance, shall not be in compliance with
     such standards, Renaissance shall deliver written notice to Manager by
     personal or overnight delivery service, return receipt requested, which
     shall specify which standard(s) are not being met and the grounds for such
     determination. Manager shall, within ten (10) days, provide a corrective
     action plan for approval by the Class A Members of the Renaissance Board.
     Upon completion of corrective action plan or resolution of the failure to
     meet standards, whichever is sooner, Manager shall, personally or by
     overnight delivery service, deliver written notice and demonstration of
     return to compliance with the standard(s). During the period from the date
     of delivery of notice of non-compliance until both a return to compliance
     is achieved and demonstration of such compliance is delivered to
     Renaissance, the management fees paid to Manager pursuant to this Agreement
     shall be decreased by ten percent (10%).

D.   D. If within the 30 days following the fee reduction, standards still are
     not met, Manager's fees shall be reduced by twenty percent (20%). If within
     the next 30 days (60 days after the original fee reduction action),
     standards are not met, Manager's fees shall

                                       18
<PAGE>
     be reduced by thirty percent (30%) and Renaissance may give 30 days notice
     of intent to terminate for non-performance. Such termination shall be
     effective at the end of such 30-day period unless Renaissance shall revoke
     the termination.

     rights or obligations hereunder, is assignable by Renaissance without the
     prior written consent of Manager, which consent shall not be unreasonably
     withheld or delayed. Manager may, without Renaissance's consent, assign
     this Agreement. However, subject to the following sentence, where such an
     assignment occurs without Renaissance's consent to an entity other than a

               and-one-half percent (1-5%) per month or part thereof, if not

      financing statements (and other applicable documents) necessary to protect

      in CUSTOMER's name. CSC Healthcare Systems shall file the appropriate
      termination statement upon CUSTOMER's final payment for the System.

14.5  SYSTEM RETURN FOR NON-PAYMENT

      In addition to any other remedy available at law or under this Agreement,
      CSC Healthcare Systems may, upon CUSTOMER's default in making payment for
      the System, enter upon CUSTOMER's site repossess the System or that
      portion of the System for which payment has not been made. If legal action
      is required, CSC Healthcare Systems may obtain a judicial order granting
      such repossession without the necessity of posting a bond as security.

14.6  TERMINATION FOR DEFAULT OR BANKRUPTCY

      14.6.1   In the event CUSTOMER fails to perform any of its obligations
               under this Agreement, CSC Healthcare Systems may, in addition to
               any other remedy available at law or under this Agreement,
               terminate this Agreement and CUSTOMER's license to use the
               Programs, by giving CUSTOMER thirty (30) days' prior written
               notice, specifying the nature of the default, If CUSTOMER cures
               such default during the thirty (30) day notice period, the notice
               of termination shall be null and void.

      14.6.2   Either patty may terminate this Agreement and CUSTOMER's license
               to use the Programs without prior notice upon an act of
               bankruptcy by or against the other party. If the other party is
               insolvent and unable to pay it debts as they mature, upon an
               assignment for the benefit of creditors, or upon dissolution of
               the other party's business, provided that the termination of this
               Agreement shall not relieve CUSTOMER of its confidentiality
               obligations.

CLIENT:          HealthSpring Management, Inc.
REQUESTED BY:    Tim Riley
PROJECT:         Support & Maintenance
SCHEDULE:        20206.H25
ACTIVITY:        Support Assistance
DATE:            March 20, 2003
CHANGE ISSUE:    Federal Tax Id Change

DESCRIPTION:

CUSTOMER would like CSCH to change the federal tax id associated with company 7
in the middle of the calendar year. CUSTOMER needs one federal tax id to be
effective from 01/01/03 through 3/31/03 and then a second federal tax id to be
effective 4/1/03-future. Two 1099's need to be generated, one for each tax id.
MHC only allows assignment of one tax id to each company. CSCH will write a
program to move the 1099 data from company 7 for periods 01/01/03-03/31/03 to a
new company that will be setup with the old federal tax id. CUSTOMER will setup
the company and provide the company id at a later date. The program will move
the 1099 totals to last year's attributes, so that month/year end will not have
to be run on the dummy company. This change will only update the 1099 data
fields in the VENDOR file. Daily processing and all other corresponding files
will remain associated with company 7. This is not covered under CUSTOMER's
current Support and Maintenance contract. All work will be performed on a time
and materials basis at a rate of $165.00 per hour. CUSTOMER will only be billed
for the actual hours used to perform this work.

IMPACT OF CHANGE:

                  Cost per hour:        $165.00

                  Estimated hours:            3

                  Total Estimated Cost: $495.00

                               SOURCE CODE RIDER

THIS SOURCE CODE RIDER (this "Rider") is attached and made a part of that
certain CSC Healthcare Systems Agreement No. 20206, dated as of _____, 1993
between CSC Healthcare Systems and BAPTIST HOSPITAL, INC. ("CUSTOMER") (the
Agreement, including the schedules attached thereto, is hereinafter referred to
as the "Agreement").

1.    General. This Rider amends and supplements the Agreement in certain
      respects. To the extent there are any inconsistencies between any
      provisions of this Rider and any provisions of the pre-printed portion of
      the Agreement or the schedules attached thereto, the provisions of this
      Rider Shall govern. Terms used herein that are defined in the Agreement
      and that are not otherwise herein defined shall have the meanings ascribed
      to them in the Agreement. Except where the contract otherwise requires,
      references to Sections or Schedules are references to Sections of, or
      Schedules attached to, the Agreement (as applicable).

2.    Additional Definitions. When used in this Rider, the following terms have
      the indicated meanings:

      "Enhancements" - Changes or additions, other than Maintenance
      Modifications, to the Source Code Programs or related documentation that
      add new functions or improved performance by changes in program design or
      coding, including changes or additions to accommodate CUSTOMER's
      particular needs.

      "Errors" - Problems caused by incorrect operation of the Source Code
      Programs or an incorrect statement or diagram in the related documentation
      that, in either case, produces incorrect results or causes incorrect
      actions to occur.

      "Maintenance Modifications" - Modifications or revisions to the Source
      Code Programs or related documentation that correct Errors therein.

      "Source Code Programs" - The computer program modules for which source
      code has been licensed as indicated in Schedule D, including source code
      and related procedural code, and (except where the context otherwise
      indicates) the related documentation.

3.    Application of Terms of Agreement to Source Code Programs. Except as
      otherwise indicated in this Rider, the terms, conditions, and restrictions
      contained in the Agreement relating to the Programs apply equally to the
      Source Code Programs. In particular, but without limiting the generality
      of the foregoing, the license to use the Source Code Programs (including
      the limited license to the source code) may be terminated on the same
      basis as the license to use the Programs.

      the Source Code Programs and related documentation and may use such works
      subject to the same limitations and restrictions as are applicable to the
      Programs pursuant to the Agreement. Except for Maintenance Modifications
      and Enhancements, CUSTOMER shall not modify the Source Code Programs or
      the related documentation. Source code license shall not be provided for

      by CSC Healthcare Systems, by or on behalf of CUSTOMER, or jointly, shall
      be and remain with CSC Healthcare Systems. CUSTOMER shall treat any such

                                SOURCE CODE RIDER

THIS SOURCE CODE RIDER (this "Rider") is attached and made a part of that
certain CSC Healthcare, Inc. Agreement No. 20206, dated as of June 13th, 2002
between CSC Healthcare, Inc. and HealthSpring Management, Inc. ("CUSTOMER")
(the Agreement, including the schedules attached thereto, is hereinafter
referred to as the "Agreement").

1.    General. This Rider amends and supplements the Agreement in certain
      respects. To the extent there are any inconsistencies between any
      provisions of this Rider and any provisions of the pre-printed portion of
      the Agreement or the schedules attached thereto, the provisions of this
      Rider shall govern. Terms used herein that are defined in the Agreement
      and that are not otherwise herein defined shall have the meanings ascribed
      to them in the Agreement. Except where the contract otherwise requires,
      references to Sections or Schedules are references to Sections of, or
      Schedules attached to, the Agreement (as applicable).

2.    Additional Definitions. When used in this Rider, the following terms have
      the indicated meanings:

      "Enhancements" - Changes or additions, other than Maintenance
      Modifications, to the Source Code Programs or related documentation that
      add new functions or improved performance by changes in program design or
      coding, including changes or additions to accommodate CUSTOMER's
      particular needs.

      "Errors" - Problems caused by incorrect operation of the Source Code
      Programs or an incorrect statement or diagram in the related documentation
      that, in either case, produces incorrect results or causes incorrect
      actions to occur.

      "Maintenance Modifications" - Modifications or revisions to the Source
      Code Programs or related documentation that correct Errors therein.

      "Source Code Programs" - The computer program modules for which source
      code has been licensed as indicated in Schedule D, including source code
      and related procedural code, and (except where the context otherwise
      indicates) the related documentation.

3.    Application of Terms of Agreement to Source Code Programs. Except as
      otherwise indicated in this Rider, the terms, conditions, and
      restrictions contained in the Agreement relating to the Programs apply
      equally to the Source Code Programs. In particular, but without limiting
      the generality of the foregoing, the license to use the Source Code
      Programs (including the limited license to the source code) may be
      terminated on the same basis as the license to use the Programs.

                           FOCAL POINT IMPLEMENTATION

The implementation of the Focal Point Decision Support System will be
accomplished in five Implementation Visits over an approximate period of four
months. Prior to the first site visit, the customer shall be responsible for
certain items which will ensure a correct environment for the Focal Point
system. These items include the purchase and/or designation of a database
server, per CSCHS' recommended configuration, which should be used for Focal
Point. If a network interface is involved, the proper communication between the
server and the network should be tested. A Database Management System (DBMS) is
another requirement for the operation of Focal Point. These requirements will be
discussed in more detail at site visit #1.

Implementation Visit #1 involves a formal kickoff meeting and operational
review. The kickoff meeting includes a detailed demonstration of-the Focal
Point DSS. The target audience for the kickoff meeting should be the business
users of the system; the MIS department, and others interested in the
capabilities of Focal Point. After the demo, discussions of the business
practices of the health plan will occur over the remaining time. During this
visit, the Focal Point consultant will interview representatives from the
various departments to better understand their business operations and to
ensure that the data captured with Focal Point is interpreted correctly.
Interviews may also take place with key decision makers in the health plan to
develop a strategy for effective use of the DSS. Finally, a sample of claims and
membership, data may be requested so that the data can be examined by the Focal
Point consultant in Southfield, Michigan.

The actual system installation occurs at the next visit (Implementation Visit
#2). This generally will take place six to eight weeks after the operational
review. In the weeks preceding the visit, a technical consultant will work with
the customer on the technical requirements to operate Focal Point, as it is
necessary for the correct environment to be in place before the visit. During
this visit the technical consultant will build the Focal Point database. The
building of the database involves extracting the data from the on-line claims
system as well as populating the data tables. The visit can last up to four days
with the technical consultant working largely independent of the customer's MIS
staff.

Implementation Visit #3 will occur three to four weeks after the installation of
the system. This visit involves training sessions conducted at the client site
by the Focal Point consultant. Three separate training sessions will take place
over the course of three days. A training session for the business users of
Focal Point will last approximately one and one-half days. This is geared for
those who will be integrating Focal Point in their business practice for use as
a decision support tool. The next day will focus on training the MIS staff, or
those who will support Focal point internally. Finally, an overview session will
last one-half day. This session is aimed at anyone else in the organization who
wants to know the capabilities of the system.

Implementation Visit #4 will occur at the first month-end following the training
described above. This visit is performed by the technical consultant and is
geared towards two objectives. The first objective involves extracting
supplemental information from the transaction processing system and building
onto the existing database. Secondly, additional technical training is provided
to the MIS staff on the maintenance of the database arid future supplemental
runs.

<PAGE>

Implementation Visit #5 will occur 4-6 weeks after visit #4. The purpose of
this visit is to provide follow-up training to the end users and technical
users of Focal Point. Additionally, the consultant will provide guidance on how
the information from the Focal Point system can be integrated into the overall
business objectives of the organization.

On-going user support and technical support for year one of the three-year
agreement is included in the Focal Point contract. Support from the consultants
or support representative via telephone is included, as well as on-site when
appropriate. Additional consultation, on a time and materials basis, is also
available when the customer needs to develop new types of reports, data
perspectives, or extracts.

If the system includes the Johns Hopkins ACG Case-Mix System then additional
training and consulting will be provided for the Physicians Profiling with
ACG's module.

1.    EXECUTIVE SUMMARY

Health Net was formed in 1984 as a Preferred Provider Organization (PPO). They
began offering a commercial HMO product in 1995 and a Plus Choice product in
1999. Health Net implemented MHC in 1997 and is currently operating on a
customized 14.6.1 release of CSC's MHC system. Current membership for the
commercial HMO and Plus Choice business is approximately 32,500 members. Health
Net also utilizes a separate RS6000 box to reprice claims for approximately
150,000 members. The repricing is handled on a separate MHC account, which is
currently running on Release 14.3. This account shares supporting files with the
MHC Release 14.6.1 account; however, members, authorizations, groups, etc. are
separate. This Statement of Work applies to performing an upgrade for the MHC
Release 14.6.1 account only. It is the responsibility of Health Net to maintain
the MHC Release 14.3 account.

Health Net uses the Focal Point product, the Code Review product and MRM. They
also use FlexTech's MSM module but are not on the most current release of the
module. Health Net will continue using the MSM module after upgrading to MHC
Release 17. The integration of the MSM module with MHC will be handled by
FlexTech. Health Net uses the MHC capitation, URM and Letter Generation modules,
but does not use the COB or EDA modules.

Health Net has the opportunity to upgrade to a standard MHC release. A standard
MHC release will minimize future upgrade costs for Health Net, as well as
provide more robust functionality. Health Net has subscribed to CSC's
Enhancement Package Program (EPP) in order to minimize their upgrade costs to
MHC Release 17. As a subscriber to EPP, Health Net will recognize the following
benefits:

-     Extended term for Support and Maintenance (past 12/31/00) on current
      release

-     Priority in queue for upgrade to Release 17

-     Discounted Professional Services rates to $100/hour, applicable to
      upgrades and/or enhancements to MHC R17 agreed to and signed by March 31,
      2001.

-     The MHC Upgrade Services agreement will provide an upgrade impact
      assessment including technical, training and configuration impacts as well
      as technical and application consultant support for addressing impacts and
      taking advantage of MHC Release 17 functionality.

1.1   OBJECTIVES

The MHC Upgrade project objectives include:

-     Moving toward a standard release of MHC

-     Minimizing future upgrade costs by moving to a standard release

-     Reviewing the current modifications [ILLEGIBLE] Health Net's MHC Release
      14.6.1 to assist in determining which modifications will not be carried
      forward due to the enhancements in Releases 15, 16 and 17

-     Reviewing the level of effort and hours required to "standardize" all
      remaining modifications being carried forward

-     Training Health Net personnel on the new enhancements in MHC Releases 15,
      16 and 17

-     Consulting on the setup for MHC Releases 15, 16 and 17

-     Identifying solutions for functionality gaps

-     Installation of the new software onto the customer account

-     Execution of the upgrade conversion on the customer's test and live data

-     On-site technical assistance with the upgrade process

1.2   STRATEGY

The key tenets of the MHC Upgrade project call for:

-     Upgrading towards a standard MHC release that supports current and future
      business requirements.

-     Because upgrading the current MHC production system would be disruptive to
      production, the current MHC Release 14.6.1 production account (this
      assumes MHC Release 14.6.1 is installed on both the test and production
      accounts prior to the upgrade) will be maintained, while the MHC Release
      14.6.1 test account is upgraded to MHC Release 17.

-     Include in the project identification of other business initiatives that
      impact claims processing: product offerings, provider relations,
      membership, decision support, regulatory requirements, HIPAA readiness and
      e-commerce to insure comprehensive requirements gathering and holistic
      solutions. Identifying related initiatives will prevent redundant effort
      and expenses.

1.3   CONSTRAINT PRIORITIZATION

This project will be managed by the following prioritization of the 3 key
constraints of scope, budget and elapsed time. This prioritization will drive
the manner in which the project is managed, the way changes of scope will be
handled, and the approach to resolving issues. These approaches are described
in Section 4.1, Management Approach.

      -     High Priority:   Time

      -     Medium Priority: Budget

      -     Low Priority:    Scope

Project measurement will validate assumptions used to estimate scope, budget and
time and identify incorrect assumptions and effort estimates related to scope.
Underestimated effort required to support the identified scope will be evaluated
on an on-going basis. Scope adjustments can be made by constraining scope,
prioritizing effort expenditures, increasing resource commitments or identifying
alternative solutions. In some cases, external projects will need to be included
in scope adjustment assessments to address expected Health Net resource, budget
and time constraints.

2.    SCOPE

The scope of this project can be defined most clearly by breaking it down into
specific categories. CSC describes these categories as Domains of Change.

There are three domains related to business scope:

       -     BUSINESS PROCESS SCOPE describes the work activities

       -     ORGANIZATION SCOPE describes the people, teams, and departments

       -     LOCATION SCOPE describes the physical locations of facilities.

There are three domains related to technical scope:

       -     APPLICATION SCOPE describes specific business software applications

                                                     [FIGURE]

      -     DATA SCOPE describes the specific data items, structures,
            relationships and business rules for information

      -     TECHNOLOGY SCOPE describes the hardware, system software,
            communication components, and development tools.

Defining scope is essential to defining mutually acceptable expectations for
project deliverables. Scope definition also insures appropriate focus and
prioritization of deliverable components. CSC will consider all components shown
as out of scope for inclusion in the MHC upgrade based on time, budget and
resource impacts using our standard change control process.

The following scope definitions define the areas that are in and out of scope.
Any areas not specifically identified as "in scope" are assumed to be "out of
scope". Specific items listed as "out of scope" are presented for clarity.

2.1   BUSINESS PROCESS SCOPE

                                    IN SCOPE

CSC will provide consulting services to assist Health Net with identifying
Health Net's business MHC upgrade impacts.

                                  OUT OF SCOPE

Health Net product offerings introduced after the project has been started are
out-of-scope and will be included if baseline time and budget allow or if
requested for inclusion through the change management process.

CSC will not address Health Net business impacts for Health Net product
offerings not supported on MHC prior to initiation of the upgrade project.

Net locations.

TABLE 3: LOCATION SCOPE

2.4   APPLICATION SCOPE

                                    IN SCOPE

MHC upgrade consulting will be provided for functionality added or modified in
MHC Releases 15 through 17, which impact Health Net's MHC Release 14.6:1
configuration and/or business requirements.

During the upgrade to Release 17, Health Net will receive a new Focal Point
extract that will function the same as it does on MHC Release 14.

                                  OUT OF SCOPE

Custom enhancements not developed or supported by CSC, code to extract data
from MHC, ad hoc reports and interfaces not supported by MHC are out of scope.

MHC configuration requires that the business requirements for each line
of business or product be defined. It is the responsibility of Health Net to
define the business requirements for each line of business and product.

Operational Assessment         The objective of the operational assessment is to identify the MHC              CSC Application
                               configuration strategy that best meets Health Net's current and future          Consultant and Health
                               business requirements. The Health Net and CSC implementation teams work          Net Project Team
                               closely together during this phase to identify the business requirements,
                               determine where there are functionality gaps between business requirements and
                               MHC functionality and identify solutions for all gaps. Solutions may include:
                               taking advantage of MHC functionality, revising or creating new processes and
                               procedures, utilizing third-party applications or enhancing MHC Some gaps will
                               have multiple solutions, each with pros, cons and tradeoffs. The set of
                               solutions is evaluated holistically from a cost-benefit perspective and a
                               configuration strategy is identified.

                               Gather, review, and document current and future business requirements for
                               upgrading to MHC Release 17. The business requirements identified during this
                               process are used to formulate the appropriate set up definition and
                               configuration for MHC.

                               Sign-off of Business Requirements documentation prior to onset of MHC Set-Up
                               Definition and documentation.

MHC Set-up                     MHC set-up is defined to support the requirements and business rules            Health Net Project
                               identified in the operational assessment. Supporting processes are improved     Team and CSC
                               and created.                                                                    Application
                                                                                                               Consultant
                               The configuration strategy drives the MHC set-up strategy. The MHC set-up
                               strategy addresses each affected functional area of MHC and identifies set-up
                               requirements, sources of information for set-up, information owners, critical
                               set-up dependencies and effort estimates to perform the actual set-up steps.

                               There is an opportunity in this phase to insure that the actual set-up is
                               efficient and clean. MHC has numerous data interdependencies. By looking at
                               MHC as a series of silo functional areas, there is a risk that some data sets
                               will be impacted by decisions related to multiple functional areas. If each
                               functional area creates or edits a data set independently, it is possible to
                               introduce redundant or inconsistent data into the configuration.

                               The Health Net and CSC implementation teams work closely together during this
                               phase. CSC MHC application consultants rely on in-depth  product knowledge
                               and set-up experience to guide and assess Health  Net set-up decisions.

System Set-Up                  MHC is set-up according to the set-up definition. Structure is defined and      Health Net
                               data is built. Processes are refined or created to support the new HHC          Project Team
                               set-up.

                               acceptance criteria to develop test plans, scenarios and scripts.               Team

                               Catalyst includes a comprehensive test planning methodology for many types of
                               testing. Test planning begins with identification of acceptance criteria and
                               concludes with developing test scenarios and test scripts. Implementation
                               testing focuses on configuration cycle tests and integration testing with
                               interfaces and other components unique to an implementation.

Model Office                   Test MHC set-up in model office environment. Health Net will utilize the test   Health Net Project
                               plan and scripts developed during test preparation. Testing includes Health     Team
                               Net's processes and procedures.

                               Review test results relative to acceptance and go/no-go criteria to determine
                               if MHC Release 17 may be safely promoted to production.

Curriculum Development         Health Net trainers create an end-user-training curriculum that includes MHC    Health Net Training
                               training and Health Net processes and procedures.

End-User Training              Health Net trainers train Health Net end-users.                                 Health Net Training

Go Live                        Go-Live is preceded by detailed plans including evaluating model office test    Health Net Project
                               results against acceptance criteria and reviewing open issues for production    Team and CSC
                               impacts. Go-Live also includes detailed conversion activities, tested via a
                               series of dress rehearsals and executed in order to insure minimal impact on
                               production. Final go-live activities are usually staged over a weekend with a
                               dedicated go-live team.

Post Production                After Go-Live, the MHC configuration is audited to insure that it meets the     Health Net and CSC
                               system set-up criteria established at the onset of the project. All open
                               issues are resolved or resolutions are implemented. The transition to Support
                               and Maintenance is completed.

4. PROJECT MANAGEMENT

4.1 MANAGEMENT APPROACH

CSC and Health Net are jointly responsible for the management of the project and
for providing the necessary resources to the project. Our joint management
objectives are focused on tightly monitoring, controlling, and balancing the
project's three key constraints: Scope (or Product), Budget and Time. To be
effective in achieving this primary management objective, the following must be
established:

      -     An agreed-upon baseline

      -     A process to monitor progress

      -     A clear means of communication

      -     An open approach for dealing with issues

      -     An objective change control procedure

      -     An approach for accepting project deliverables

      -     A definition of what constitutes project completion

This section describes the basic approaches that will be used to provide this
type of control.

4.1.1 AGREED-UPON BASELINE

This Upgrade Proposal is the foundation for all the key project management
activities. It identifies the work activities that will be tracked, defines the
boundaries for scope control, identifies responsibilities, and clarifies many of
the areas where issues may arise that need to be managed.

The Upgrade Proposal is then used as the basis for creating a detailed project
plan for all the work activities to be performed on the project. Every activity
will have an estimate of work effort. All project team members, from CSC and
Health Net, will be assigned these activities and this will determine the cost
of the activity based on the cost of the individual team members assigned to it.

Once all the activities are allocated to team members, the project plan is
leveled and loaded against the calendar. This completed plan represents the
baseline plan. This plan will provide the key milestone dates to track schedule
progress.

prohibited

                                       13
<PAGE>

The summation of all activity costs from the base lined project plan, plus
expenses, plus the costs of purchased items like hardware, software, and other
services, will represent the budget that the CSC / Health Net management team
will track against.

4.1.2 PROCESS TO MONITOR PROGRESS

The detailed project plan is the key vehicle for measuring progress. The
specific activities that each team member works on, and their progress against
completing those activities, are an objective measure of where the project
stands against the schedule and budget. To capture this information every team
member, both CSC and Health Net, will record and report their actual hours
spent on project activities against the budgeted time in the project plan. In
addition, each team member will provide estimates of the effort remaining on
activities that have not been completed during the regularly scheduled
conference calls.

4.1.3 MEANS OF COMMUNICATION

Because CSC and Health Net are responsible for managing this project, it is
imperative that we use a formal process to provide timely and accurate
communication between the organizations. There are two key vehicles for
providing this communication: a weekly status report and a weekly status
meeting.

All team members will report progress and status weekly. This information, and
the analysis of it, will be summarized into a project status report for Health
Net and CSC management. This report contains the following information:

      -     Significant Problems/Actions Taken

      -     Progress Summary

      -     Accomplishments

      -     Planned Accomplishments

      -     Budget Status

      -     Issues Log (discussed later)

The weekly project status meeting will be used to review the project status and
open issues in the status report. The CSC and Health Net management team must be
committed to having this meeting and making it effective. The keys to making the
meeting worthwhile are:

      -     Having the meetings often enough so that timely information is
            available

      -     Focusing the meeting on major issues or areas where management
            action or intervention is required

      -     Making sure that the information provided is accurate and objective

4.1.4 APPROACH FOR DEALING WITH ISSUES

Every project has issues that hinder progress. It is important to ensure that
these issues are identified and resolved quickly by the right person. The first
step in effectively dealing with these issues is to make the entire team aware
of the importance of identifying issues and getting proper resolution. We will
then use the following procedure to identify issues so that they can be visibly
tracked.

      -     IDENTIFY ISSUES. When the project begins, we will start identifying
            any issues that could hinder our ability to meet the objectives of
            the project. Issues can be identified by anyone involved with the
            project.

      -     DOCUMENT THE ISSUE. The person who identifies the issue must
            document it.

      -     ASSIGN RESPONSIBILITY FOR RESOLVING ISSUES. The CSC / Health Net
            management team will determine the appropriate individual who will
            be responsible for resolving each issue. The responsible person must
            be an

<PAGE>

            individual who has the knowledge and authority to make decisions
            regarding the issue. The management team will also assign a priority
            to the issue.

      -     MONITOR AND CONTROL PROGRESS. All issues will be tracked on an issue
            log that will be maintained to formally track the status and
            resolution of the issues.

      -     REPORT PROGRESS ON ISSUE RESOLUTION. As mentioned earlier, the
            issues log will be a part of the weekly status report and discussed
            in the weekly status meeting.

      -     COMMUNICATE ISSUE RESOLUTION. The issues log and documented
            resolutions of issues will be made available to all team members.

In the event that an issue cannot be resolved in a reasonable time frame, to the
mutual satisfaction of CSC and Health Net, we will determine a mutually
acceptable approach to escalating it to the next level of management.

4.1.5 CHANGE CONTROL PROCESS

The Change Control Process is a crucial mechanism that can affect the success or
failure of this project. This process is the primary vehicle for containing
scope and enables Health Net's management to have the opportunity to make timely
trade-offs between the three key project variables of cost, time and scope. It
is imperative that potential changes are identified early, documented carefully,
and resolved at the appropriate levels of responsibility.

Changes are broadly defined as work activities or work products not originally
planned for as defined by this MHC Upgrade Proposal. More specifically, changes
will include:

      -     Any scope items not listed in this Upgrade Proposal (See Section 2,
            Scope)

      -     Participation in activities not previously included in this Upgrade
            Proposal's list of work activities during the weekly status meetings

      -     Provision or development of deliverables not included in this
            Upgrade Proposal

      -     A change in responsibilities, as defined in this Upgrade Proposal
            between CSC / Health Net, including reallocation of project staffing

      -     Any rework of completed activities or accepted deliverables

      -     Investigative work to determine the impact of major changes

In order to manage change properly, a Change Control Process will be established
to identify, record, assess, and approve changes to the project. CSC and Health
Net will follow this process to classify, prioritize, approve, or reject
changes. Change requests need to be clearly defined, including cost, resource,
and schedule implications, to allow CSC and Health Net management to make
appropriate decisions. CSC will always need prior authorization and approval of
expenditures by Health Net before starting work on changes.

The change control process will not be used to report or identify the impact of:

      -     Assumptions not remaining valid

      -     Delays caused by schedule slippage

      -     Variances of actual work effort from estimated effort

This information will be identified and tracked as part of the monitoring and
reporting processes defined in Sections 4.1.2 and 4.1.3.

At the beginning of the project CSC and Health Net management will institute a
mutually acceptable change control procedure.

4.1.6 RISK MANAGEMENT

Critical project risks that must be managed, tracked, and mitigated will be
formally documented and reviewed. Each risk identified will be assessed in terms
of the impact it could potentially have on the success of the project and a
mitigation strategy will be identified which is commensurate with this potential
impact.

4.1.7 AGREED-UPON BASELINE

This Statement of Work and project plan is the foundation for all the key
project management activities. It identifies the work activities that will be
tracked, defines the boundaries for scope control, identifies responsibilities,
and clarifies many of the areas where issues may arise that need to be managed.

The Statement of Work is then used as the basis for creating a detailed project
plan for all the work activities to be performed on the project. This completed
plan represents the baseline plan. This plan will provide the key milestone
dates to track schedule progress.

Every activity has an estimated duration and/or work effort. All project team
members, from CSC and Health Net, will be assigned these activities and this
will determine the cost of the activity based on the cost of the individual team
members assigned to it.

The summation of all activity costs from the baselined project plan, plus
expenses, plus the costs of purchased items like hardware, software, and other
services, will represent the budget that the CSC/Health Net management team
will track against.

4.1.8 PROCESS TO MONITOR PROGRESS

The detailed project plan is the key vehicle for measuring progress. The
specific activities that each team member works on, and their progress against
completing those activities, are an objective measure of where the project
stands against the schedule and budget. To capture this information every team
member, both CSC and Health Net, will record and report their actual hours spent
on project activities against the budgeted time in the project plan. In
addition, each team member will provide estimates of the effort remaining on
activities that have not been completed.

4.1.9 MEANS OF COMMUNICATION

The CSC and Health Net project managers are responsible for routinely and
frequently assessing project status and reporting status to the Health Net
project sponsor and CSC management verbally and in writing. In addition, the CSC

4.1.10 ACCEPTANCE OF DELIVERABLES

All of the completed deliverables identified in this SOW will be formally
submitted for final review and approval. This section outlines the key
components to this acceptance process. CSC and Health Net will mutually agree
to a more detailed acceptance procedure and specific acceptance criteria. The
key components are:

      -     There will be only one person identified as the designated acceptor
            for each deliverable

      -     The deliverables will include an acceptance form for signature

      -     Each deliverable will have clearly documented, objective acceptance
            criteria

      -     There will be a specified time-frame for acceptance/rejection of
            each deliverable

      -     Deliverables will be deemed accepted if the acceptance time-frame is
            exceeded

In order to avoid delays in the schedule and the associated increased cost due
to slow deliverable review, deliverables not reviewed and approved within the
specified review period will be considered accepted. Feedback supplied after the
review period will be evaluated as a change of scope.

4.1.11 PROJECT COMPLETION CRITERIA

The project will be completed when all of the deliverables identified in Section
3.2 have been accepted. The Health Net project management team is responsible
for accepting and approving CSC deliverables. Failure to indicate acceptance
within 5 business days will be assumed as an indication of acceptance. Quality
of deliverables will be based on agreement regarding deliverable standards
between Health Net and CSC project management. Issues regarding quality of
deliverables that these individuals are unable to resolve will be escalated to
CSC Business Services and Health Net Management.

4.2 PROJECT ORGANIZATION

                          [PROJECT ORGANIZATION CHART]

CSC and Health Net will jointly manage the project. The project team includes
Health Net representatives from functional areas representing the span of
operational areas impacted by a integration and reconfiguration project. Health
Net representatives may in turn delegate additional resources from their
departments. Additional resources are required for enhancement set-up tasks and
model office testing. See Section 4.3, Roles and Responsibilities for additional
information.

Health Net project team members are responsible for representing the functional
areas, which they represent in a leadership capacity. Generally, these
individuals must be perceived as leaders by their colleagues, have expertise in
their functional areas, and be able to identify issues and promote resolution of
issues for their functional areas with an understanding of the impacts on other
functional areas. They must understand Health Net's current and future business
requirements and strategic objectives and weigh decisions against business
requirements and strategic criteria. They must be sensitive to the impacts that
a project of this magnitude will have on their colleagues and engender
enthusiasm and support for the goals and objectives of the project. Finally,
they must help their functional areas prepare for the changes, which a
successful project will require. Project team membership will require
commitment, frequently in the form of work in excess of routine working hours.

(1) The Health Net project sponsor may assume responsibilities of the Health Net
project manager until a Health Net project manager is assigned to the project.

(2) The Health Net project manager will be assigned early in the project and the
CSC and Health Net-project managers will work in a partnership capacity. Issues
which the CSC / Health Net project management team cannot resolve will be
escalated to the Health Net project sponsor and CSC management. Specific roles
of the project managers may be further defined based on project requirements,
optimization of time utilization and other factors. A few responsibilities,
including managing CSC resources and coordinating with CSC management will
remain the responsibility of the CSC project manager.

5. PRODUCT DEVELOPMENT

5.1 CARRY FORWARD OVERVIEW

This upgrade estimate will be valid for all modifications developed by CSC,
which have been installed on Health Net's  machine on or before October 1, 2000.
The carry forward of enhancements to a new software release involves the
following tasks:

-     Carry forward previous release modification designs. This involves
      designing the modification on the new release of MHC software. This also
      includes targeting enhancements for a future standard release of MHC
      software.

-     Carry forward the enhanced programs, including changing the original
      coding to work with the new release of MHC.

-     Updates to the database conversion routines to accommodate any data
      elements added due to enhancements.

-     Carry forward of Customer Service changes to the new release of MHC
      software (if applicable).

-     Testing of the enhanced MHC software.

The upgrade to MHC Release 17 is the first step towards moving Health Net to the
'standard' model of MHC. The carry-forward enhancements listed in this
Statement of Work, if implemented, will be placed in a queue for enhancements to
target for the base MHC product or a separate module in a future release. The
enhancements will also be redesigned during this upgrade effort to prepare for
inclusion into a future release of MHC. This means that Health Net will continue
to pay the support and maintenance fees for the enhancement on a monthly basis
through the time that Health Net upgrades to and implements a version of MHC
which includes the enhancement(s) as part of the base product or a separate
module. If Health Net upgrades to a subsequent release of MHC, after Release 17,
but before a carry-forward enhancement is included in the base product or a
separate module, Health Net will be responsible for the carry-forward fees of
the enhancement when upgrading to that subsequent release.

5.2 SUMMARY OF ENHANCEMENTS

The following is a summary of the enhancements that currently exist on Health
Net's account, with the estimated hours to implement the enhancements on a
Release 17 account.

      1. 8-00132  OB Information                               47 - 52

      2. 8-00216  Track Member Liability Amount on Claims      81 - 90

      3. 8-00467  Auto ER Pay                                  85 - 92

      4. 8-00563  Move Print of Zero Checks to End             53 - 60

      5. 8-00564  Flag Non-Pars for UM                         62 - 68

      6. 8-00577  IPA Warning for UM                           28 - 33

      7. 9-00038  Pay Lesser of Calculated vs. Billed          50 - 55

      8. 9-00375  EOBs for Denied Claims                       45 - 60

                                     Carry Forward Hours:     451 - 510

<PAGE>

      NOTE: The following enhancements will not be moved to Release 17:

      1. 8-00429  Update Claims to Financial by Table

      2. 8-00405  Lag Report Break on region Option

      3. 8-00187  Adjudicate Claims Against All Diagnosis Codes

      4. 8-00131  Enhance Duplicate Claims Checking

      5. 8-00148  Open Authorizations/Precerts for One Episode of Care

      6.          Code Review Interface

5.3 DATABASE CONVERSION ANALYSIS

Health Net will be upgrading from Release 14.6.1 to Release 17 of MHC, which
will email three release upgrades. Since several of Health Net's enhancements
added new data elements, the upgrade routines will be reviewed to determine if
any impact is made by the addition of the new data elements.

      Estimated hours for this upgrade analysis and conversion processing
changes: 80-100

Note: This analysis assumes that Health Net is not currently using the Open
Authorization/Precert enhancement (8-00148) so that a conversion will not be
required for that enhancement's data.

5.4 TECHNICAL UPGRADE ASSISTANCE

With CSC's knowledge of the MHC file structure and many years of experience in
performing upgrades, we recommend that CSC provide on-site assistance with the
upgrade process. The upgrade will be scheduled to minimize the system down time,
which is necessary during the upgrade process. Health Net personnel should be
available during the upgrade process to ensure that any questions or decisions
are addressed in a timely manner. The upgrade will include the following:

      -     Installation of the new software onto the customer account.

      -     Installation of the standard System Builder+ files.

      -     Work in conjunction with Health Net and the CSC consultant to define
            any default values that will be used in the data conversion.

      -     Execution of the upgrade conversion on the customer's test and live
            data. The "live" conversion will be executed approximately four to
            six weeks after the "test" upgrade (exact timeframe will be
            determined after the "test" upgrade is reviewed). This timeframe
            will allow Health Net to become familiar with the new software, as
            well as provide sufficient time for user testing of the converted
            data and any added enhancements.

      -     Perform audits to ensure that the conversion executed successfully
            on the customer's data.

      -     Provide immediate trouble-shooting to resolve any technical problems
            that may arise. Quickly research and provide answers to any
            questions that may arise.

            Estimated hours (test upgrade): 80-100

            Estimated hours (live upgrade): 80-100

            TOTAL TECHNICAL UPGRADE ASSISTANCE HOURS: 160-200

            Note: A technical representative will remain on-site on the first
            day of processing on the new release of MHC. This is included in the
            live upgrade estimate.

7.4 PAYMENT SCHEDULE

CSC will submit invoices monthly for work performed: Invoice payment is required
within 30 days of receipt of invoice. Questions regarding invoice detail should
be directed to the CSC Project Manager.

8. PROJECT PLAN

Attached to this Statement of Work is a draft high-level Project Plan. A
detailed Project Plan will be created by the CSC Project Manager for all work
activities to be performed on the project once the upgrade proposal is finalized
and approved. Every activity will have an estimate of work effort. All project
team members, from CSC and Health Net, will be assigned these activities and
this determines the cost of the activity based on the cost of the individual
team members assigned to it.

Once all the activities are allocated to team members, the project plan is
leveled and loaded against the calendar. This completed plan represents the
baseline plan. This plan will provide the key milestone dates to track schedule
progress.

The summation of all activity costs from the baseline project plan, plus
expenses, plus the costs of purchased items like hardware, software, and other
services/will represent the budget that the CSC/Health Net management team will
track against.

9. MHC ENHANCEMENT SUMMARY - RELEASE 15, 16 AND 17

NATIONAL PAYER IDENTIFIER

NATIONAL PAYER IDENTIFIER (8-00606-R15)

In accordance with the requirements of the Health Insurance Portability and
Accountability Act of 1996 (HIPAA), a new field for assignment of the
HCFA-assigned payer identification number, was added to employer group, and
Federal Tax ID number screens. The payer ID is also stored in general claims.
This is a strictly an informational field.

PROVIDERS/VENDORS

NATIONAL PROVIDER IDENTIFIER (8-00607-R15)

Each individual, group, and organization of providers will be assigned a unique
National Provider Identifier (NPI). A new NPI field was added to Provider,
Vendor and Region code screens, however, until the NPI requirements are
finalized, the NPI number is used for informational purposes only. NPI is also
stored in the Credentialing module.

VARIOUS PROVIDER DATA ENTRY ENHANCEMENTS (8-00852-R16)

The following enhancements were added for provider data entry:

A PCP panel limit may now be defined at the line-of-business level to track PCP
members separately for each LOB (i.e.: Medicare versus Commercial). In
combination, panel limits at the LOB level are calculated against the global
panel limit for the provider. The system will use a global panel limit if no
limit is defined at the LOB level.

The panel size assigned to a PCP may be restricted by the age and gender of the
member. A report is also generated during Membership Month End for members who
no longer meet the PCP age/gender panel restrictions. This report is also
available upon demand.

Both providers and vendors have new fields to store an office name and fax
number for each business address. Office names and fax numbers are also included
on the Provider Codes Report (HC412.3.1) and Vendor Codes Report (HC412.8.1).

An unlimited number of specialties may be assigned to the provider at Field #4
of HC411.3, where previously only four specialties could be entered.

10 additional user defined fields were created for users to store additional
provider data. The sub-screen containing these fields may be accessed through
the new UDF' Change Field option on HC411.3.

INCREASE DRG & PER DIEM FLEXIBILITY (8-00858-R16)

DRG and per diem pricing has been enhanced to better automate claims
reimbursement for vendors with complex contracting arrangements.

Enhancements include:

      -     Moving per diem fee schedules to the region level within a LOB,

      -     Adding multiple sets of rates by effective date, rather than just
            "current" and "previous" rates,

      -     Adding "step-down" per diems, where the rate may vary depending on a
            set number of days,

      -     Making DRG and per diem pricing flags on the vendor date sensitive,

      -     Adding the ability to specify a per diem rate by place of service.

      -     Use "Lesser of" Logic on Per Diem Claims (8-00928-R16)

Per Diem pricing may now be calculated to pay the lesser of the per diem
allowance or the requested amount as determined by a LOB flag setting.

PROCEDURE CODE MODIFIER ENHANCEMENT (8-01015-R16)

Modifiers may be defined at the LOB and/or region level by effective date.
Within each procedure code/range assignment, a modifier may be defined to add
to, subtract from or replace the procedure fee allowance by a percentage or flat
dollar amount. Enter/Update Procedure Code Modifiers is now an SB+ screen.

DISCOUNT TABLES (0-00032-R16)

Discounts may now be assigned to a provider and/or a vendor at the region level
within each LOB. Date sensitive discounts may be defined as a default discount
applicable to all services, or restricted by and combination of procedure
code(s), procedure group(s), claim type(s), place(s) of service, diagnosis
code(s), diagnostic group(s), DRG code(s), and/or pricing method for par/non-par
or all providers. Discounts may apply either front-end or back-end and may be
based upon a percentage or flat dollar amount taken from the pricing method fee
allowance. A conversion program to clear current vendor discount information is
provided. This program also allows a 'default' discount table to be created and
assigned to select all vendors based on LOB and region combinations.

ENHANCED TIN LOOK-UP (EPP)

Provider and vendors may be selected based upon a TIN number. Entering
T,xxxxxxxxx (where xxxxxxxxxx represents a TIN), from a provider prompt displays
a list of providers with the TIN. Entering T,xxxxxxxx from a vendor prompt
displays a list of vendors assigned to the TIN. In either case, a Federal Tax ID
Display screen appears for the selected TIN, displaying associated MHC provider
or vendor code(s), name(s) and address(es).

CAPITATION

AUTOMATE THE REDUCTION OF CHARGEBACK CLAIMS FROM A PCPs CAPITATION CHECK
(8-00999-R16)

To accommodate capitation arrangements where covering physicians are paid FFS
and such payment should be deducted from the PCP's capitation check, MHC was
enhanced to automate the chargeback process based upon a user defined set of
criteria.

ASSIGN MAXIMUM NUMBER OF MONTHS FOR RETROACTIVE CAPITATION PAYMENTS
(9-00042-R16)

Both the PCP and non-PCP capitation calculation processes have been enhanced to
allow definition of a set number of months for retroactivity. The retroactive
month limit is defined at the LOB level and may be overridden at the
provider/region/capitation level. If no value exists at the
provider/region/capitation level, then the default value at the LOB level will
be used. In either case no more than 12 months of retroactivity may be
calculated.

EFFECTIVE DATE DRIVE CAPITATION RATE TABLES (8-00878-R16)

PCP and Non-PCP capitation rate tables were enhanced to be effective date driven
in order, to maintain a history of capitation rate changes.

SORT CAPITATION REPORTS BY VENDOR (8-01014-R16)

The following capitation reports now provide an option to sort by vendor.

      -     HC153.2.1 PCP Capitation Summary

      -     HC153.2.2 PCP Capitation Detail

      -     HC153.2.3 PCP Capitation Adjustment Detail

      -     HC152.2.1 Non-PCP Capitation Summary

      -     HC152.2.2 Non-PCP Capitation Detail

      -     HC152.2.3 Non-PCP Capitation Adjustment Detail

USE VENDOR TO DETERMINE NON-PCP (EPP)

A new flag will be added to the Initialize Utilization Constants screen (IN2.2)
that will allow health plans to use the service provider's vendor for non-PCP
determination. When this functionality is activated and the claim provider's
vendor matches the vendor of an assigned non-PCP, the capacity of the claim will
be set to the non-PCP capacity code.

ENROLLMENT

AUTO PCP ASSIGNMENT (EPP)

During membership data-in processing a new table will determine to which PCP an
enrolled member should be assigned. The new table will store the PCP assignment
parameters by effective date and may vary by LOB. When members are 'manually'
entered, PCPs that match the criteria in the PCP tables will display in order of
appropriateness for manual selection of the correct PCP.

AUTOMATE TRANSFER OF PCP's PANEL (EPP)

When a PCP leaves a provider network, a new program allows transfer of that
PCP's patients to another PCP by effective date. A report will be generated if
the new PCP panel size is exceeded; however, the user may override the new PCP
panel size allowing the transfer to take place.

AUTOMATE NON-PCP ASSIGNMENT AND TRANSFER (EPP)

A new screen may be used to create panels of non-PCP providers, which may then
be assigned to PCPs, LOBs or regions. These non-PCP panels are effective date
driven. These panels may be automatically assigned to newly enrolled members,
those transferring PCPs, regions or groups, or when changes within a panel are
made.

SUSPEND CLAIMS AT GROUP LEVEL (EPP)

A new flag at the Employer Group level may be set to suspend all claims for the
group when the claim date of service is on or after the group suspension
effective date. Once the group is released from suspension, a mass group
unsuspension process exists to release the associated claims. This process
removes the group suspension warning message from all of the groups pended
claims; however, claims suspended for reasons other than the group suspension
flag will remain in a suspended state for manual review and release.

MEMBER LEVEL BENEFITS (8-00386-R15)

For groups using ASO billing method 4 or 5, the group may offer a choice of
benefits to their employees and employee dependents. On the Enter/Update Group
Benefit Information screen, flags are set to indicate:

Whether the employer group permits member level benefit selection

Whether the dependent member will choose from either the benefit types selected
by the subscriber or the benefit types that are valid for the group. (This flag
setting at the group level may be overridden on Enroll Subscribers or Change
Subscriber's Data screens.)

A new option was added to the Member Inquiry Control Screen (INQ) to view a
member's benefit type(s).

MEMBERSHIP RETROACTIVITY REPORT (6-10340-R15)

Membership Data-in Processing was modified to process retroactivity in a manner
similar to the Disenroll/Reenroll a Member screen (HC115). The user may choose
to not process retroactivity; to detect retroactivity and add a message to the
existing reports; or to generate a full retroactivity report. The choices are
available from the Set Up Membership Data-in Constants screen, which was
rewritten in SB+. Retroactivity may be run for audits, updates, and automatic
disenrollment. In addition, the full retroactivity report is available from a
new Membership Retroactivity Report screen.

BENEFITS

BENEFIT LIMIT ENHANCEMENTS (8-00384-R15)

The same functionality available for Coinsurance definition has been added to
the Copayment option. The following fields may be defined for a copay:

      -     Expiration period

      -     Number of years

      -     Limit by either a percentage or dollar amount

      -     Limit by either a visit or dollar amount

      -     Maximum copayment per visit amount

Benefit Limit screen HC345 now allows assignment of multiple groupers including
deductible, coinsurance and out-of-pocket.

NON-COVERED BENEFIT DEFINITION WITH AUTO-DENY FUNCTIONALITY (EPP)

A health plan may indicate that specific services/diagnoses are not covered by a
plan through definition of non-covered benefits. There are two means of defining
non-covered benefits. If only the benefit's Non-Covered flag is set to 'Y', the
claim will suspend with a standard 'non-covered benefit' message. If the
Non-Covered flag is set to 'Y' and a denial claim adjustment code is assigned to
the benefit, the claim adjustment code will be automatically assigned to
procedure lines matching the non-covered benefit and all values except the
requested amount will be set to zero. The second method fully automates denial
of non-covered services. This enhancement encompasses claims processing through
manual, tape and electronic claims entry.

COPY UTILITY FOR BENEFIT CODES AND BENEFIT PLANS WITH AUTOMATIC EMPLOYER GROUP
(EPP)

New utilities were created to copy a benefit code or benefit plan. The new copy
functionality is available as a Change Field option (COPY) on HC348 and HC343.
When a benefit plan is modified, another new screen allows health plans to
indicate if all employer groups assigned to that benefit plan should be
automatically updated.

CLAIMS ADJUDICATION

LINE ITEM DIAGNOSIS (6-00825-R15)

Up to four of the diagnosis codes entered on HC441 may be linked to each
procedure line on HC441.1. When positioned at the DIAG field of any procedure
line on HC441.1, up to eight of the diagnosis codes display at the lower left
hand section of the screen with associated reference numbers. Keying through the
DIAG field will automatically assign diagnosis codes (up to four) to the
procedure line.

UTILIZE ALL DIAGNOSIS CODES DURING CLAIMS, AUTHORIZATION AND PRECERT
ADJUDICATION (EPP)

A new initialize flag allows health plans to determine how many diagnoses per
line to consider during the adjudication process to determine benefits for
claims, authorizations and precertifications.

FREE FORM & LONG DESCRIPTION CLAIM ADJUSTMENT CODES (PSR 9-10919-R15.3)

Health plans may now define an extended claim adjustment code description
consisting of three lines with sixty characters per line. In addition, by
entering FFA at the ADJ field on HC441.1, a new System Builder Screen allows
entry of free form comments with the same size limit as a predefined Claim
Adjustment Code Description. The new change field option 'FFA#' allows a user to
view the free form comment for a specific line (#). EOBs and RAs were enhanced
to print the full free form or extended Claim Adjustment Code description.

ASSIGN MULTIPLE CLAIM ADJUSTMENT CODES (R-15)

Multiple claim adjustment codes may be assigned to each procedure line and a new
change field option 'PA#' may be used to page through the claim adjustment
codes for a specific procedure line (#).

LINE ITEM DENIAL (6-00418-R-15)

A new flag has been added to Claim Adjustment Codes allowing it to be used for
denial only purposes. MHC has been enhanced to allow denial of services by
individual claim line using one of the 'denial' type Claim Adjustment Codes.
Denial of the claim line may be performed through entry of DNx at the Change
Field, where 'x' represents the line item to be denied. The user will then be
prompted to enter a denial claim adjustment code that is automatically assigned
to the procedure line. The Denied Services report was renamed and modified to
list all denied claim lines based upon selection criteria.

EARLY PERIODIC SCREENING, DIAGNOSIS, AND TREATMENT (EPSDT) (8-00650-R15)

Health plans may now designate specific procedure and diagnosis codes as EPSDT
related. When an EPSDT tagged procedure and/or diagnosis is entered on a claim
of a member under the age of21; the EPSDT flag on the claim line is
automatically set to 'Y'. Users may also override the authorization requirement
when the procedure is identified as EPSDT related.

TIMELY CLAIM FILING FLAG (EPP)

Health plans may define a claim-filing limit at the employer group or LOB level
by using the new 'TC' change field option on these screens. Timely filing limits
may be defined for participating and non-participating providers. The filing
limit may be defined to represent the number of days between the date of service
and either the date the claim is received by the health plan, or the date of
entry into the MHC. If the claim line exceeds the timely filing limit, the claim
line may be suspended or automatically denied based upon the timely filing
criteria.

FLEXIBLE DUPLICATE CLAIMS CHECKING CRITERIA (EPP)

Duplicate claim checking logic is modified to allow a health plan to vary
duplicate claim criteria by LOB.

The pre-defined duplicate claim data elements with some user definition
flexibility include:

      -     Patient Identifier-MHC number, Social Security Number, Health Plan
            ID, Recipient ID, Medicare ID.

                    Date of Service

      -     Procedure Code

Users may customize the duplicate check criteria by adding:

      -     Provider Identifier - MHC provider ID, provider TIN, UPIN, or
            provider NPI

      -     Vendor Identifier - MHC vendor ID, Vendor TIN, Vendor NPI

      -     Place of Service

      -     Procedure Code Modifier

Users may also be able to define the number of matches required for a
'suspension or warning' and the number of matches required for an automatic
denial. The program will check the entire date range on a claim line for
overlaps and matches with dates on previous claims.

AUTOMATICALLY RECALCULATE MANUALLY ADJUSTED CLAIM LINES (EPP)

As an alternative to the current process of manual claim line recalculation when
one of the line item amounts has been manually modified, the system will be
enhanced to automatically recalculate the claim line based upon the values of
the manually changed field.

The recalculation process may be activated from a new initialize flag with
options to auto recalculate, prompt the user for system recalculation or
continue to follow the current manual adjustment process.

The PAID AMOUNT, WITHHOLD, COPAY, COINSURANCE, DEDUCTIBLE and DISCOUNT amount on
a claim line will automatically be recalculated if manual adjustments are made
to any of the following fields: MAX.AMT, COB.AMT, WHOLD, DISCOUNT, COPAY, COINS
and/or DED.AMT.

No automatic recalculation of fields will occur if the Paid Amount is manually
changed.

INTERIM CLAIMS PROCESSING (EPP)

Because, hospitals often need to submit an interim bill to payers for patients
who have extended facility stays, a new prompt will be added to all claims
adjudication processes to capture an interim claim indicator from the UB92 Type
of Bill Code. The presence of this indicator will bypass the requirement of
discharge date entry.

HCFA1500 AND UB92 CLAIMS ENTRY SCREENS (R16.1)

A new series of three screens were designed to capture all data submitted on a
HCFA1500 claim form. Fields within the screen flow in the same order found on a
HCFA150Q form. These new screens are used for data capture and reporting only.
When filed, a MASTER CLAIM record is created and adjudication still takes place
on the HC441, HC441.1 and HC442 screens.

<PAGE>

Four new screen(s) were created to capture UB92 data. These screens are laid out
in the same order as a UB92 claim form to capture all data fields within the
UB92 claim form. All new fields are for data capture and reporting only. Ten new
code files were also created for UB92 claims for code validation purposes.
Reports for each of the following code files are also available:

         Type of Bill             Admit Source                Condition Codes

         Admit Type               Patient Status Codes        Revenue Codes

         Condition Codes          Occurrence Codes            Value Codes

         Employment Status Code

PROCESSING EFFICIENCIES

EFFECTIVE & INACTIVATION DATES FOR PROCEDURE AND DIAGNOSIS CODES (R17)

Effective and Inactive dates will be added to both procedure code as and
diagnosis codes. The field length for procedure codes will also be expanded from
7 to 11.

MULTIPLE MODIFIERS FOR A PROCEDURE CODE (R17)

An enhancement will be made to capture up to 4 modifier codes on a claim line.
Only the first modifier entered will be considered for pricing purposes.

INQUIRY ONLY SCREENS (EPP)

New functionality allows users access to various code files in an 'inquiry only'
mode. Access to the new inquiry screen will be available from the change field
HC441, HC442.2, HC431, HC4102 and a number of other screens.

CUSTOMER SERVICE

INQ ADDED TO CSIM SCREENS (8-00386-R15)

An inquiry (INQ) option has been added to the change fields of the following
CISM screens to enable the user to view a member's benefit types as well as the
other options available:

      -     CSIM200 - Enter/Update Calls

      -     CSIM306 - Enter/Update Callers

      -     CSIM406 - Caller Inquiry

      -     CSIM701 - Member Document Inquiry

MEDICAL MANAGEMENT

INQUIRE AND ASSIGN PROCEDURE GROUP OR PROCEDURE CODE TO PRE-CERTIFICATIONS (R15)

Users now have the capability to inquire and assign either a procedure code or a
procedure group on HC4102, Initial Certification - Screen 1.

AUTHORIZATION ACCUMULATOR INQUIRIES (6-00352-R15)

Entry of 'AA' at the change field for claims, authorizations and
pre-certifications accesses HC128, the Authorization Inquiry screens. This
screen lists the benefit limit, with the authorized, approved; claimed and
available limits for a benefit.

ADD BENEFIT BALANCE TO HC128 (EPP)

The Accumulator Inquiry screen (HC128) will be enhanced to display the remaining
benefit balance. The balance will be the difference between the benefit limit
and the amount claimed.

DIAGNOSIS UTILIZATION REPORT (6-00333-R15)

This new report includes services associated with a diagnosis code (range),
diagnostic group or DRG within a specified date range. The report may be
selected by provider(s), provider specialty(s), member(s), LOB(s), region(s),
group(s), age range(s) and/or member gender. Denied services may be included or
excluded and two levels of sort are offered.

OPEN AUTHORIZATIONS AND PRE-CERTIFICATIONS (EPP)

Health plans will have the ability to enter a single
authorization/pre-certification record to cover a full episode of care. Claims
from different providers may be matched to a single
authorization/pre-certification record. This will be accomplished by defining
the authorization/pre-certification as a 'global auth' record. With an 'global
auth' record, multiple 'referred to' providers may be entered on a new
sub-screen accessible from the change field on HC431 or HC4102, or new providers
associated to the episode by place of service and date range, may be updated to
this sub-screen automatically through claims processing routines. In addition,
referral inquiry screens will be modified to display the phrase 'Open
Authorization' in place of the vendor name when open authorizations/referrals
exist.

RESTRICT UPDATES BY ADJUDICATOR CODE (EPP)

Currently options /15, /16, /17 and /18 on the Certification Entry/Update screen
allow a user to update the data in the associated records. Health plans will now
be able to limit access to these records based upon the users SB+ User ID.
Options available will include inquiry only mode or update capability.

MEDICARE RECONCILIATION MODULE

MEDICARE RECONCILIATION MODULE (MRM) (CR012225-CR012230-R16.1)

The MHC Medicare Reconciliation Module (MRM) was brought into HCFA compliance.
It now accommodates the revised Membership Detail Report, which includes
adjustment data used for the new Premium Calculation and Reconciliation.

The following critical areas were addressed in this enhancement:

      -     The program that receives the HCFA Reply file was changed to include
            the new data elements of the Membership Detail report.

      -     The AAPCC cells now include 'Rescaling Factors'.

      -     Membership billing records were revised to include the new risk
            payment data elements.

      -     Reconciliation reports were revised for the new data elements
            between HMO and HCFA.

      -     Premium Revenue calculates according to risk adjustment data.

      -     Results of risk adjusted premium process were blended with the
            historical method to calculate gross premium.

      -     GL allocations were expanded/refine to recognize new revenue
            segments (i.e. risk component, etc.).

LASER PRINTING

RXLASER (8-00773-R15)

Several screens and programs have been created that will allow a health plan to
select a laser report output for EOBs, group bills, remittance advices, accounts
payable checks, membership cards, other reports. The laser output is selected
and entered through the laser screens. Once all forms are complete, this
information is sent to RxLaser to produce a laser printer chip containing all
the required information. The laser chip is returned to the health plan site for
installation in a laser printer. Once the laser printer chip is installed, the
information can be transferred from the test account to the live account.
Thereafter, whenever a laser output designation is made, the laser printer chip
in the printer recognizes the commands and produces results according to your
selected laser output. Standard output versions will continue to be available
for these functions.

DATA TRANSACTION ACCESS (DTA)

DATA TRANSACTION ACCESS (S003231 - R15.3)

Health plans may require the use of database changes in the production
environment to trigger subsequent database changes in the data warehouse
environment. These database changes are identified by data files in the uniVerse
database environment. A standard subroutine (referred to as CUST.HOOK) will be
supplied for data tracking proposes. To meet its business needs, a health plan
may modify the CUST.HOOK subroutine for specific files or create additional
files to track data changes. These files and client-written subroutines will not
be considered part of the standard MHC R15.3 package and will not be maintained
by CSCH. This functionality is switch driven at a high level and is on a
go-forward basis. No transaction logs from history will be built. Many of the
uniVerse data files that are monitored for file update activity are also
accessed directly by client specific ancillary systems such as Appointment
Scheduling, Pharmacy, and LAB.

ELECTRONIC DATA INTERCHANGE

Since the MHC Electronic Commerce Modules do not format the data into an ANSI
X12 format, it is essential that a mapping tool, clearinghouse or some other
data translation utility or service be used to map the incoming and outgoing
data from and to the mandated X12 formats. CSC recommends the use of an EDI
mapping tool or our Direct Connect EDI clearinghouse. This provides a way to
receive the X12 transaction, map it to the MHC interface format, run the load or
extract process, validate the data, and load it into the MHC Database. MHC will
handle the following HIPAA transactions in batch mode.

DATA PROCESSING ENHANCEMENTS (7-00443, 7-00444, 8-00667 - R15)

A new MHC screen enables users to define valid EDI Trading Partner codes. The
data-in processing routines have been enhanced to load data for EDI processing.
The data-out processes have been enhanced to output data for outbound mapping to
standard EDI documents through a translator.

HIPAA TRANSACTION SETS (R17)

MHC will be enhanced to support the following HIPAAANSI X12 batch transactions:

      -     S005868 - EDI 270-271 Eligibility & Benefits Inquiry & Response

            MHC will be modified to process a request for eligibility and return
            a response. Requests for eligibility may be generic or specific. If
            there are no errors (reject reasons) found during the processing of
            the request, MHC will return a response detailing the member's
            eligibility for the request. If the member is eligible for the
            request, deductible, co-pay, and/or coinsurance information will
            also be returned, if applicable.

      -     S006186 - EDI 820 Premium Payment

            A new module will be developed on Accounts Receivable to allow
            premium payment information for group billing to be received
            electronically. Transmitted data will be required to be in the ASC
            X12 820, Payroll Deducted and Other Group Premium Payment for
            Insurance Products, format.

      -     S005960 - EDI 834 Enrollment

            Changes will be made to the existing Membership From Data-In module
            in MHC to support an interface with data from an ANSI XI2 834
            version 4010. Data elements not used in MHC processing will be
            captured and stored in the FM.EDI.834 file. Data elements in the
            FM.EDI.834 file will not have an edit/inquiry screen and will not
            impact membership processing in MHC.

            The MHC Members From Data-In module will be enhanced to update the
            MEMBERS file with the key to the FM.EDI.834 file and to allow the
            printing of multiple ID cards.

      -     S005961 - EDI 835 Remittance Advices

            MHC will be enhanced to allow it to generate an outbound UNIX
            flat-file containing the data necessary to translate into a standard
            ANSI X12 835 for claim payments and/or remittance advice statements
            processed through MHC's standard accounts payable. The ability to
            send electronic claim payments (EFTs), electronic remittance advice
            statements (ERA's) or both in a single 835 record will be added to
            MHC.

      -     S005299 - EDI 837 Claims - Institutional and Professional

            for any reason (because of negligence or otherwise) to furnish or
            supply to Customer the services described in the Schedule of
            Services, the exclusive liability or responsibility of CSCH
            hereunder shall be to furnish to Customer the correct report or data
            or to resume the services or deliver the reports contemplated, as
            the case may be, as soon as reasonably practicable. CSCH shall not
            be liable or responsible to Customer or to any third party for any
            loss or damage which it or any of them may suffer or incur by reason
            of such error, omission or failure.

      b.    EXCEPT AS SPECIFICALLY SET FORTH HEREIN, CSCH MAKES NO WARRANTIES,
            EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
            WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

            for any reason (because of negligence or otherwise) to furnish or
            supply to Customer the services described in the Schedule of
            Services, the exclusive liability or responsibility of CSCH
            hereunder shall be to furnish to Customer the correct report or data
            or to resume the services or deliver the reports contemplated, as
            the case may be, as soon as reasonably practicable. CSCH shall not
            be liable or responsible to Customer or to any third party for any

CHANGE ISSUE:   Assistance in producing a tape of standard MHC programs

Health Net has requested Professional Services assistance in producing a tape of
the 26 standard programs that are being modified to incorporate the MRM-in-MHC
11.1. Health Net is unable to determine what user modifications have been made
because the modifications were not stored separately from the standard source
code. Professional Services will produce a tape of the source code for the 26
programs so that Health Net can do a comparison to determine what user
modifications have been made.

All work is to be done on a time and materials basis at the rate of $100.00 per
hour. It is estimated that this effort will encompass five to ten hours.

DESCRIPTION OF/REASON FOR CHANGE

The original scope of work for the system compare initiative (20206.F05) did not
include a comparison of System Builder programs. In order to properly compare
HNETTN's system with the CSCHS standard support system, the comparison of the
System Builder programs is required.

                         PROGRAMMING SERVICES WORK ORDER

This Schedule is governed by the terms and conditions of Agreement number 20206
between CSC Healthcare, Inc. and HEALTHNET MANAGEMENT, INC.

   Date. If the Enhancement Package is terminated due to a lack of Subscription
   Fees, all Subscription Fees (but not any of the Deposits) will be returned
   within thirty (30) days of termination.

3. SPECIFICATIONS. Unless the Enhancement Package is previously terminated
   pursuant to Section 1 or Section 2 of this Schedule F, CSCH will deliver
   problem statements, approaches to programming, and high level functionality
   descriptions (collectively the "Specifications") to CUSTOMER by March 8, 2000
   ("Specification Due Date") for the purpose of allowing the Subscribers to
   review the Specifications. CSCH may use its sole discretion to delay the
   Specification Due Date. If a Specification Due Date extension is unacceptable
   to Subscriber, Subscriber may terminate this Schedule F and request the
   return of Subscriber's Subscription Fee (the Deposit is not refundable).
   Subscriber acknowledges that CSCH's work in developing the Specifications for
   the Enhancement Package constitutes valuable consideration. CUSTOMER agrees
   that the Specifications constitute confidential and proprietary information
   which cannot be disclosed to third parties without CSCH's prior written
   permission. CSCH intends to distribute the Specifications to Subscribers as
   those Specifications are developed in order the maximize the time Subscribers
   have to review the Specifications. CSCH may deliver all of the Specifications
   to Subscribers before the Specification Due Date, and for the purposes of
   interpreting this Schedule F, the date upon which all of the Specifications
   have been delivered to a Subscriber is hereby defined as that Subscriber's
   "Specification Delivery Date."

4. SPECIFICATION MODIFICATIONS. It is CSCH's desire that the Specifications
   provided to Subscribers on the Specifications Delivery Date shall be final in
   terms of the basic functionality provided. However, CSCH does maintain sole
   control over those Specifications and reserves the right to make commercially
   reasonable changes to the Specifications. Subscribers shall be notified in
   writing of any such changes. If Subscriber is dissatisfied with the
   Specifications in any way, Subscriber's sole remedy is to withdraw as a
   Subscriber of the Enhancement Package and receive a full refund of the
   Subscription Fee (but not the Deposit). If a Subscriber (including CUSTOMER)
   seeks to receive a refund of a Subscription Fee, that Subscriber must first
   provide CSCH with a written notice of cancellation no later than seven (7)
   days after the Specifications Delivery Date (the "Refund Notice Due Date").
   If the number of non-refunded Subscription Fees on the day after the Refund
   Notice Due Date is less than twenty (20), CSCH may at its sole discretion
   terminate the Enhancement Package and this Schedule F within ninety (90) days
   of the Refund Notice Due Date. If the Enhancement Package is terminated due
   to refunded Subscription Fees, all Subscription Fees (but not any of the
   Deposits) will be returned within thirty (30) days of termination. CUSTOMER
   acknowledges in advance that CSCH may lawfully ignore all refund requests
   received after the Refund Notice Due Date. NO SUBSCRIPTION FEE REFUNDS WILL
   BE

This Schedule is governed by the terms and conditions of Agreement number 20206
between CSC Healthcare. Inc. and HEALTHNET MANAGEMENT, INC.

      PROVIDED AFTER THE REFUND NOTICE DUE DATE.

5.    CSCH'S DISCLOSURE RIGHTS. To the extent that the Agreement between
      CUSTOMER and CSCH would prohibit identifying.CUSTOMER as a Subscriber or
      a,potential Subscriber in the Enhancement Package program, the
      Agreement is hereby amended to allow CSCH to disclose the following facts
      to former, active and potential Subscribers in the Enhancement Package
      program: (a) whether or not CUSTOMER has paid the Deposit; (b) whether or
      not CUSTOMER has executed an Enhancement Package Schedule F; (c) whether
      or not CUSTOMER has paid a Subscription Fee; and (d) whether or not
      CUSTOMER has requested a refund of their particular Subscription Fee.

                      INCENTIVES FOR BECOMING A SUBSCRIBER

6.    PRICE INCENTIVES. Neither the Deposit nor the Subscription Fee constitutes
      consideration for actual implementation of the Enhancement Package.
      However, CUSTOMER (if the status of a Subscriber is maintained) will be
      eligible to receive certain services at discounted rates. CUSTOMER will
      receive the discounted rate of $100/hour for professional services for any
      MHC release through the release of MHC Release 17 or February
      28, 2001, whichever occurs first. The discounted price will end at the
      earlier of: (a) the day that CUSTOMER is no longer a Subscriber; or (b)
      the Enhancement Package is available for delivery.

7.    UPGRADE PRIORITY. CUSTOMER (if the status of a Subscriber is maintained)
      will receive priority over non-subscribers for MHC Release 16.0
      implementations.

8.    FIXED PRICE UPGRADE ANALYSIS. After the release of MHC 16 in March 2000,
      CUSTOMER will be eligible to purchase detailed and client specific upgrade
      analyses for a cost of Ten Thousand ($10,000.00) Dollars ("Upgrade
      Analysis Fee"). The Upgrade Analysis Fee will ultimately be applied as a
      credit only to CUSTOMER's release upgrade implementation service charges,
      only if the CUSTOMER ultimately upgrades, and will include (a)
      implementation and data conversion; (b) integrated consulting, project
      management and training; and (c) upgrades of non-standard enhancement
      modules. The Upgrade Analysis Fee is independent of the Deposit and
      Subscription Fee.

9.    DELAYING THE UPGRADE FROM MHC RELEASE 14.4. CSCH will provide support and
      maintenance services for only the two most recent MHC releases. However,
      if CUSTOMER uses MHC Release 14.4 and CUSTOMER maintains the status, as
      a Subscriber, CUSTOMER will be eligible to receive support and maintenance
      through December 31, 2001 (a one year extension

between CSC Healthcare, Inc. and HEALTHNET MANAGEMENT, INC.

      from the existing December 31, 2000 deadline for upgrading).

10.   SUPPORT AND MAINTENANCE. CUSTOMER's support and maintenance fees will be
      frozen (so long as CUSTOMER maintains the status of a Subscriber) through
      December 2000 for the CUSTOMER's MHC system as it currently exists. Any
      new custom modifications will still require additional support and
      maintenance fees.

11.   RELEASE ELIGIBILITY PLANS AND RELEASE 15 CLIENTS. A reduced subscription
      price of Fifty Thousand ($50,000.00) Dollars ("Discounted Subscription
      Fee") is available to the following participants so long as they timely
      comply with the requirements of Sections 1 and 2 of this Schedule F: (a)
      existing MHC Release 15 clients and (b) Release Eligibility Plans ("REP")
      as defined in the sole discretion of CSCH. For the purposes of tabulating
      the number of Subscription Fees pursuant to Sections 1, 2, and 4 of this
      Schedule F, a Discounted Subscription Fee counts as only one half (1/2) of
      a Subscription Fee.

12.   COST UNDERAGE. To the extent that CSCH in its sole discretion determines
      that the cost (based on CSCH's standard commercial rates) to develop the
      Enhancement Package was less then previously expected and that such cost
      underage results in a financial contribution to the development process of
      less than Five Hundred Thousand ($500,000.00) Dollars by CSCH, CSCH will
      provide-Subscribers with a pro-rata (based on the amount of the
      subscription fee) refund of the cost underage so that CSCH's Enhancement
      Package contribution will remain at Five Hundred Thousand ($500,000.00)
      Dollars. Any refunds pursuant to this Section 12 would be provided within
      ninety (90) days of CSCH's determination that a cost underage occurred,
      and no such investigation by CSCH need be made until sixty (60) days after
      the implementation process is completed.

13.   LATE SUBSCRIBERS. Entities desiring to participate in the Enhancement
      Package who have not paid a Subscription Fee by the Subscription Due Date
      may become Subscribers by paying CSCH a fee of Two Hundred Fifty Thousand
      ($250,000.00) Dollars ("Late Subscription Fee"). To the extent that Late
      Subscription Fees increase the total number of non-refunded Subscription
      Fees received by CSCH (Discount Subscription Fees in Section 11 count as
      only one half of a Subscription Fee), CSCH will share the additional
      non-refunded revenue (the "Surplus") with all Subscribers who rendered
      payment before the Subscription Due Date without subsequently requesting a
      refund (the "Charter Subscribers"). If such a Surplus exists, 50% of it
      will be kept by CSCH, and the remaining 50% will be distributed to the
      Charter Subscribers on a pro-rata (based upon the amount of the fee paid)
      basis.

      THIS SCHEDULE F IS HEREBY CAPPED AT THE AMOUNT OF THE SUBSCRIPTION FEE
      ACTUALLY PAID BY CUSTOMER. CUSTOMER acknowledges that the allocation of
      risk contained in this Schedule F is fair and just because the Enhancement

      face of an "Order of Precedence" Clause in the Agreement that would
      otherwise require that the Agreement control the conflicted issue. CSCH's
      standard Change Control Process is not applicable to this Schedule F or to
      the Enhancement Package.

17.   INTEGRATED DOCUMENT. With respect to the Enhancement Package, this
      Schedule F contains all of the terms and conditions between the parties.
      Promises and terms with regards to the Enhancement Package, whether made

</TABLE>

SERVICES CANCELLATION POLICY FOR HOURLY SERVICES

In the event that you must cancel scheduled services (on-site meetings or

required or the following penalties will apply:

[ ]   Training - 100% of estimated reserved seats or on-site training

[ ]   Program/Project Mgt/Consulting - Scheduled services at 50% of the regular
      billing rate.

If scheduled services exceed two (2) weeks, the penalty applies only to the
first 2 weeks of services.

SERVICES CANCELLATION POLICY FOR DEDICATED RESOURCES

In the event, that you must cancel a dedicated resource (billed at a monthly
rate), a minimum of thirty (30) business days' notice is required or the
following penalties will apply:

[ ]   Program/Project Mgt/Consulting - Scheduled services at 50% of the regular
      billing rate.

If scheduled services exceed one (1) month, the penalty applies only to the

                                                                          Page 2

ENGAGEMENT CONFIRMATION NOTICE

As a follow-up to your services request, CSC will provide you with a
confirmation notice. This document will set forth the dates of work, the number
of eight (8) hour days that will be provided, and what contract schedule the
work will fall under. In the event that you must cancel a confirmed request, the
confirmation notice will be the basis for calculating the appropriate penalty.
Please refer to the attached Engagement Confirmation Notice for more details.

TRAVEL BILLING RATES

As a standard, all travel for on-site services will be conducted during the
normal business week (Monday through Friday). Travel during this time will be
non-billable. Upon your request CSC staff may be able to travel on weekends and
CSC holidays. The rate for weekend and holiday travel is $120.00/hour. These
requests will also be authorized with the Engagement Confirmation Notice.

STANDARD SYSTEM MODIFICATIONS

Standard system modification requests will flow as follows and result in two (2)
different contract schedules:

1.    You submit your modification request to CSC through a CSR or on-site
      consultant.

2.    CSC proposes a high-level estimate for design and development (time spent
      doing a high-level estimate is included in the cost of the detail design
      and will be billable if work is approved).

3.    You verbally approve high-level estimate.

4.    CSC prepares a contract for time and materials design.

5.    Upon your authorization, detail design is scheduled.

6.    Upon your approval of the detail design, CSC prepares a contract for fixed
      price development.

7.    Upon your authorization, development is scheduled.

CUSTOM MODIFICATIONS

A special surcharge will be added to your monthly support and maintenance
invoice for all non-standard, custom system modifications. This is in addition
to costs associated with the design and development of the custom modification.
The annual fee will equal 50% of the total design and development cost (actual,
not estimated, costs will be used to calculate the fee). For example, a $10,000
custom modification will result in a monthly custom support/maintenance fee
equal to $417.

PREPAID SUPPORT AND MAINTENANCE

There will be a 1.2% increase in prepaid support and maintenance fees for
customers who are on releases less than MHC 15.0. This 1.2% increase equates to
a monthly increase of 6.25% and will include the base MHC product and most
modules. Since all limited and interim support and maintenance agreements expire
on December 31,1998, a new Schedule H will be sent to all customers on an active
agreement. The Schedule H will serve to indicate your price increase, as well as
to provide you with your annual renewable agreement for support and
maintenance. Release 15.0 customers will receive a schedule with the new Release
15.0 pricing. All existing contract provisions will be taken into account in
relation to fee increases.

If you have any questions regarding the new rates, feel free to contact me at
205-967-8200.

Sincerely,

TRAVEL POLICY: EXPENSES AND TRAVEL TIME

When a CSC employee travels on behalf of the Customer, all expenses incurred in
that travel are billable to the Customer. Time required to travel is not billed
to the Customer if the travel occurs during the business week. However, time

Mr. John Davis
Health Net, Inc.
44 Vantage Way, Suite 300
Nashville, TN 37228

Dear Mr. Davis:

SUBJECT: MHC Year 2000 Testing

Although CSC Healthcare has mounted an extensive campaign to inform and support
our clients about the MHC product and the Year 2000, several of our clients have
recently requested additional information regarding our internal Year 2000
testing program. Based on CSC Corporate Policy, CSC Healthcare is unable to
release the details of our Year 2000 test plans and results. However, our
Development and Quality Assurance teams compiled a summary document that
described our MHC testing methodology and commitment to Year 2000 readiness.
This document, entitled "MHC Year 2000 Testing Methodology" is attached.

Recently, we have received several requests asking if there are other MHC
clients who conducted their own independent test of the product and would they
be willing to share the results of this testing with their fellow MHC users. In
light of these requests, CSCH is proposing to our clients that we become a
"clearinghouse" for any Year 2000 test data that you might be willing to share
with the other MHC clients. Your testing data would be securely stored at our
Southfield, Michigan office and any current MHC client could request copies to
provide to them. If this approach is well received, CSCH hopes that by
facilitating this sharing of information, each client will be able to create
their own file of independent test information that could be made available to
federal and state institutions having a need to know.

If you are interested in sharing your MHC Year 2000 test plans and results with
other MHC clients, please send this "information to:

-     Electronic format (preferably MS Word 7 or Word 97): email to
      kryskamp@csc.

-     Hard copies: Michele Ryskamp; CSC Healthcare Group, 26711 Northwestern
      Hwy, Suite 600; Southfield, MI 48034-2156

If you have questions or are interested in obtaining information from other
clients about the testing they conducted, please contact Connie Hein via
telephone at 615,799.2960 or via email at chein@ccc.com. We request that you
provide this information by mid-September to allow other clients sufficient time
to benefit their Year 2000 testing efforts.

CSC Healthcare hopes that you find this service to be valuable to your company.

Sincerely,

/s/ Michael Mark

  UNDER U.S. YEAR 2000 INFORMATION AND READINESS DISCLOSURE ACT (P.L. 105-271)

                              MHC AND THE YEAR 2000

THE PROBLEM

We recently confronted the worldwide challenge to develop an effective strategy
concerning the "Year 2000" issue. The question we debated as we developed our
strategy was this: How can we alter the software to handle Year 2000 issues
effectively, without adversely affecting the productivity of our existing
customers? Our customers have invested a great deal in teaching their personnel
to use the system and in developing training materials. Many of our screens and
reports are filled to capacity with essential information. Changing the screens
and reports to use four digit years, rather than two, would require that many
screens and reports be completely redesigned. In some cases, we would be forced
to move information to other places. We agreed that this would place an undue
burden on our customers. Fortunately, our analysts conceived a strategy that
will effectively circumvent this problem.

HOW MHC ORIGINALLY HANDLED DATES

Most dates displayed the MMDDYY format throughout the MHC system. Some dates
have been stored as month/year, year only or period. However, birth dates in MHC
have always displayed a full four-digit year.

OUR YEAR 2000 READY STRATEGY

To avoid the complications, costs, and productivity losses our customers would
otherwise face, MHC will continue to display and report dates in their current
formats. However, with the exception of birth dates, a user must assume that the
years 00 to 29 refer to the twenty-first century (2000 to 2029) and that all
other years refer to the twentieth century when reading dates. MHC displays
birth dates with a full four-digit year. Therefore, users can readily
distinguish a member bom in 1901 from one born in 2001. The programs have been
modified to convert dates to a four-digit format before doing calculations
involving the year. Within the data files, dates previously stored as
month/year, year only or period have been changed to store those dates with a
four-digit year. In addition, all hard coded century logic was removed.

THE IMPLEMENTATION OF OUR YEAR 2000 SOLUTION

The year 2000 solution was implemented in the MHC release 14.4 and 15. Changes
were made by the programming department according to the detail design, and
then each object was tested before being passed over to the Quality Assurance
team.

YEAR 2000 TESTING APPROACH

Our testing approach has encompassed several phases. The first phase focused on
program and date field specific changes. Examples of these types of tests are:

-     Each programming change related to Year 2000 was verified through a
      process relevant to the change itself. For example, if an on-line program
      was changed to write the century based on the year entered, dates within
      the 21st century were added and the record displayed within the file to
      verify correct writing of the century value.

  UNDER U.S. YEAR 2000 INFORMATION AND READINESS DISCLOSURE ACT (P.L. 105-271)

-     For processes and reports using a Start Date; output was successfully
      generated to verify that the processed data was either on or after the
      start date of the selection. This testing used start dates in both the
      20th and 21st centuries.

-     For date fields that do not allow a future date, it was successfully
      verified that a date entered that is greater than the current date is
      still considered an error.

-     Standard reports were generated for dates within the 21st century to
      verify that the reports were reading and printing the new century
      correctly.

-     Claims payment cycles, premium billing runs, capitation runs, member
      months, and check runs were successfully processed with updates as the
      system date changed from 12/31/99 into 01/01/00.

Additional phases of testing verified future date compliance for processes,
including testing for the millennium cross over and dates beyond January 1,
2000. These phases focused on the impact to our programs when the system date
was set to a year within the 21st century. Examples of these types of tests are:

-     With the system date set to various dates within the year 2000, batch
      processes using date ranges were successfully executed using the following
      ranges:

      12/31/99 to 01/01/00

      01/01/00 to 01/01/01

      02/28/00 to 02/29/00 to 03/01/00 (to test allowing for leap year)

      12/31/2000 (for year end processes)

      The output from these processes was verified to ensure that the data
      processed or extracted was within the date ranges specified. Additionally,
      it was verified that dates with a year between 00 and 29 were considered
      to be greater than dates with a year between 30 and 99. This is because in
      accordance with the scope of our changes, any year between 00 and 29 is
      considered to be in 21st century and any year between 30 and 99 is
      considered to be in the 20th century.

Please note: MHC Release 14.4 or 15 may not perform correctly if it has been
customized or modified by non-CSC personnel. Moreover, the Year 2000
functionality of MHC Release 14.4 or 15 may be adversely affected by other
components or elements of the system in which MHC Release 14.4 or 15 is
employed, including:

-     Incompatible equipment, operating system software, or other application
      software with which MHC Release 14.4 or 15 must interface, and

-     Use of MHC Release 14.4 or 15 with data transmitted from other application
      programs that contain incompatible date representations or are otherwise
      in a form incompatible with MHC Release 14.4 or 15.

CUSTOMER SPECIFIC YEAR 2000 TESTING

PHASE ONE:

Following the completion of the Quality Assurance testing for the standard MHC
Release 14:4 application, each customer's current version was examined to
determine the appropriate procedures to upgrade to Release 14.4. We evaluated
the programming customizations that CSC Healthcare performed on their existing
software version and applied those customizations to Release 14.4. During this
process, we also corrected Year 2000 problems with the customizations. The
application was tested for account verification by accessing and verifying
functionality for each screen.

PHASE TWO:

Following the Quality Assurance testing for the standard MHC Release 14.4, and
the account verification following the upgrade, a level of additional testing
was completed following the inclusion of various custom modifications to Release
14.4 which supported the client's application.

This level of testing placed focus on verifying the correct operation of areas
of the MHC application which were impacted by custom modifications specific to
the customer.

The MHC Quality Assurance team validated that all phases of testing were
completed. We required that every customer perform additional integrated systems
testing prior to moving into production.

THE FUTURE OF MHC

As our product continues to evolve, our year 2000 efforts will also continue.
Our current Quality Assurance process has been modified to ensure all future
changes and modifications to the MHC system function in accordance with our year
2000 strategy.

This Schedule is governed by the terms and conditions of Agreement number 20206
between CSC Healthcare, Inc. and HEALTH NET MANAGEMENT, INC..

      TASK DESCRIPTION:        Standard Claims Editing Interfaces (SCEI)

      START DATE:              To be determined

      STATEMENT OF WORK:

      The SCEI enhancement will be a standard, separately licensed, module for
      Claim Editing interfaces to MHC. This enhancement will be a switch-driven
      module offering a variety of options and will replace the previous MHC
      Claim editing interface that facilitated downloading claim data to an
      earlier version of HPR's (now McKesson HBOC) CodeReview on another
      computer system. This enhancement will also replace individual customer
      modifications for claim editing. The SCEI enhancement will enable CUSTOMER
      to define what type of claim should process through the claim editing
      software and facilitate the application of claim editing advice to the
      claim while it is being approved. The SCEI enhancement is an interface
      only and therefore requires CUSTOMER to purchase a third-party Claim
      Editing software package. The enhancement shall include a new claim
      editing setup menu created to assist the CUSTOMER in defining the
      processing criteria for claim editing and what MHC action should be taken
      in response to the claim editing advice. The claim adjudication and
      approval process will be enhanced to automatically extract the claim data
      meeting that defined claim editing criteria, and either facilitate
      downloading it to another system or process it through the UNIX server
      claim editing software where it will auto-apply its advice to the claim
      depending on the options utilized, and report on the claim changes and
      resulting savings.

      THE SCEI ENHANCEMENT WILL OFFER THREE POSSIBLE PROCESSING MODES FOR CLAIM
      EDITING:

      1.    The "one-way" processing mode will flag claim data that meets the
            claim editing criteria, as the claim is being approved, then suspend
            and flag the claims. A new process will extract the claim data and
            load it into a download file. The data out utility will then be used
            to format the claim data into the correct layout for subsequent
            transfer to the claim editing software. The results of the claim
            editing must then be manually applied to the claim.

      2.    The "two-way" processing mode will flag claim data that meets the
            claim editing criteria, as the claim is being approved, then suspend
            and flag the claims. A new process will extract the claim data, pass
            it to the UNIX server claim editing software, and apply the claim
            editing advice to the claim. This claim editing approach minimizes
            claim adjudicator

This Schedule is governed by the terms and conditions of Agreement number 20206

            effort and time requirements, but increases the total processing
            time for the claim because it is suspended until the claim is
            "batch" processed through claim editing.

      3.    The "on-line" processing mode will extract the claim data that meets
            the claim editing criteria as the claim is being approved, pass it
            to the UNIX server claim editing software and apply the claim
            editing advice to the claim. While the claim is being approved and
            processed through the claim editing software, the MHC user is
            required to wait, i.e., other processing in that HostAccess session
            is not possible. This claim editing approach minimizes claim
            adjudicator effort and the total processing time for the claim, but
            increases the adjudicator "wait" time while claim editing is
            performed.

      THE THIRD-PARTY CLAIM EDITING SOFTWARE OPTIONS WITH THE SCEI ENHANCEMENT
      SHALL INCLUDE THE FOLLOWING:

      1.    HBOC ClaimCheck with ClaimReview will be available in an "on-line"
            or "two-way" or "one-way" processing mode. This enhancement does not
            include SmartSuspense.

      2.    HBOC Commercial CodeReview with or without the Medicare "add-on"
            module will be available in a "two-way" or "one-way" processing
            mode. This enhancement does not include "custom" knowledge bases nor
            does it include ProMatch.

      3.    Other third-party options will be available in a "one-way"
            processing mode. This option will require data-out configuration for
            the download process.

      The SCEI enhancement is being joint-funded.

Joint Funding Enhancement Cost Due Upon Execution: $15,000.00*

Additional Monthly Support Fee: $500.00 (shall begin after installation of
module in test environment)

*Price does not include travel and per diem expenses.

The enhancement can be retrofit into MHC Release 17.1, with a retrofit fee, if
the CUSTOMER elects to receive the functionality prior to MHC Release 18. The
retrofit fee will be a discounted hourly rate of  $100 per hour for joint
funding CUSTOMER.

                      THE PREPAID ENHANCEMENT POOL PROGRAM

1.    PARTICIPANT FEES. The monthly fee for the Prepaid Enhancement Pool Program
      is based on a minimum of 24 months, which begins November 1, 2002 and ends
      October 31, 2004. THE MONTHLY FEE IS $3,300.00. CUSTOMER acknowledges that
      the Participant Fee does not constitute consideration for actual
      implementation of the Prepaid Enhancement Pool Program.

2.    PARTICIPANT REQUIREMENTS. This Schedule F is entered into in anticipation
      of and contingent upon, CSCH's receipt of minimum aggregate participation
      fees of $1.3 million. If CSCH does not receive this level of commitment by
      November 1, 2002, CSCH may, at its sole discretion, terminate the Prepaid
      Enhancement Pool Program and this Schedule F. If the Prepaid Enhancement
      Pool Program is terminated due to a lack of funding, all fees will be
      returned within thirty (30) days of termination.

3.    SPECIFICATIONS. Unless the Prepaid Enhancement Pool Program is terminated
      pursuant to Section 2 of this Schedule F, CSCH will deliver the
      functional specifications for the Prepaid Enhancement Pool hours to
      CUSTOMER on or after November 8, 2002 ("Specification Due Date") for the
      purpose of allowing the participant to review the functional
      specifications. CSCH may, in its sole discretion, change the Specification
      Due Date if necessary. CUSTOMER acknowledges that CSCH's work in
      developing the functional specifications for the Prepaid Enhancement Pool
      Program shall constitute valuable consideration. CUSTOMER further agrees
      that the functional specifications constitute confidential and proprietary
      information, which cannot be disclosed to third parties without CSCH's
      prior written permission.

4.    CSCH'S DISCLOSURE RIGHTS. To the extent that the Agreement between
      CUSTOMER and

This Schedule is governed by the terms and conditions of Agreement number 20206
between CSC Healthcare, Inc. and HEALTHSPRING MANAGEMENT, INC.

      CSCH would prohibit identifying CUSTOMER as a participant or a potential
      participant in the Prepaid Enhancement Pool Program, the Agreement is
      hereby amended to allow CSCH to disclose the following facts to former,
      active and potential participants in the Prepaid Enhancement Pool Program:
      (a) whether or not CUSTOMER has executed a Prepaid Enhancement Pool
      Program Schedule F; (b) whether or not CUSTOMER has paid a Participant
      Fee; and (c) whether or not CUSTOMER has requested to terminate the
      Prepaid Enhancement Pool Program.

                      INCENTIVES FOR BECOMING A PARTICIPANT

5.    PRICE INCENTIVES. CUSTOMER will receive the discounted rate of $130/hour
      for the hours allocated to the pool enhancement.

6.    VOTING PRIVILEGES. CUSTOMER will have voting rights on how the Prepaid
      Enhancement Pool Program hours will be used.

7.    DELIVERY OF FUNCTIONALITY. CUSTOMER can receive the Prepaid Enhancement
      Pool Program functionality sooner than non-participants, if the
      functionality is included in a release.

8.    SUPPORT AND MAINTENANCE. CUSTOMER's support and maintenance fees
      (exclusive of third party products) will not be subject to CSCH's
      potential annual support and maintenance increases through December 31,
      2004 for the CUSTOMER's MHC system, as it currently exists. Custom
      modifications will still require additional support and maintenance fees.

9.    LATE PARTICIPANTS. Entities desiring to participate in the Prepaid
      Enhancement Pool Program who have not committed by November 1, 2002 may
      become a participant by retroactively paying all monthly fees, plus an
      applicable surcharge.

      Section 2, the benefits conveyed by CSCH to CUSTOMER in Sections 5-9 of

      Schedule F shall survive termination.

11.   LIABILITY LIMITATION. ANY AND ALL POTENTIAL LIABILITY ARISING FROM OR
      RELATING TO THIS SCHEDULE F SHALL NOT EXCEED AND IS HEREBY CAPPED AT THE
      AMOUNT OF THE PARTICIPANT FEE ACTUALLY PAID BY CUSTOMER. CUSTOMER

      participants, including CUSTOMER, with a unique mechanism for obtaining
      potentially valuable work at a discounted price due to the shared nature
      of the development costs. CUSTOMER further acknowledges that CSCH would
      not offer to provide the Prepaid Enhancement Pool Program to CUSTOMER
      without the benefit of the risk allocation, contract flexibility and other
      rights provided to CUSTOMER herein.

12.   ORDER OF PRECEDENCE. In the event of an express conflict between the
      Agreement between CUSTOMER and CSCH and this Schedule F, this Schedule F
      shall control. This Schedule F shall control even in the face of an "Order
      of Precedence". Clause in the Agreement that would otherwise require that
      the Agreement control the conflicted issue. CSCH's standard Change Control
      Process is not applicable to this Schedule F or to the Prepaid Enhancement
      Pool Program.

13.   INTEGRATED DOCUMENT. With respect to the Prepaid Enhancement Pool Program,
      this Schedule F contains all of the terms and conditions between the
      parties. Promises and terms with regard to the Prepaid Enhancement Pool
      Program, whether made in an oral or written form, are not binding upon the
      parties unless contained in this Schedule F, the Agreement between the
      parties, or in a subsequent written amendment of the Agreement and its
      accompanying schedules and exhibits.

14.   In the event CSCH terminates the Prepaid Enhancement Pool Program at any
      time, CUSTOMER will receive any functionality that has been completed as
      of the date of termination from the Prepaid Enhancement Pool Program.

      3.4 AUTHORIZED CALLERS Customer must identify a Designated Caller and an
      Alternate Designated Caller, and if applicable under this Agreement, an

      is responsible for implementing any temporary procedures requested by
      CSCHS while a permanent solution is being sought. The extent of support
      provided via modem varies with Equipment type. Customer acknowledges and
      agrees that CSCHS shall not be responsible for a failure to provide
      support services if Customer's remote equipment is unavailable for any
      reason at the time CSCHS attempts communication with Customer's Equipment.

      4.3 ON-SITE ASSISTANCE If CSCHS cannot resolve a problem remotely,
      additional resources may be utilized via CSCHS's escalation management
      procedures, which may result in a on-site visit with the Designated

      4.4 SOFTWARE PROBLEM REPORTING Customer shall report problems with the
      Software or updates by submitting a software service request to CSCHS.

      request. CSCHS retains the right to determine the final disposition of all
      reported problems. Upon Customer's report of a critical Software problem,
      CSCHS may, at its discretion, provide Customer with a workaround or object
      code modification (patch), if available.

      4.5 NON-CURRENT REVISIONS CSCHS shall have no obligation to support
      versions of the Software which pre-date the most current two release
      levels ("Current Revision Levels"). Support for Software problems for

      and materials rates.

      support, and receive the following:

            from the manufacturer. Media charges will be charged for each
            update.

            4.6.2 REFERENCE MANUAL UPDATES CSCHS will send one copy of the

            manual updates may be purchased through CSCHS.

      or correction of applications software, providing supplies or accessories,

            expense for the purpose of allowing CSCHS to provide software
            support.

MHC PREPAID INTERIM SUPPORT AND MAINTENANCE PLAN

      This Prepaid Interim Support and Maintenance Plan for "Non-Year 2000
      ready" releases of MHC features individual support and maintenance fees.
      Customer participation in the plan is required and will be in effect until
      the installation and implementation of MHC 14.4, MHC 15.0, MHS, or
      Meridia or December 31, 1998 whichever comes first. CSC Healthcare Systems
      reserves the right to discontinue support and maintenance services at
      anytime during the life of this interim plan upon 30 days written notice.

      Systems' Year 2000 ready release, new "full coverage" support and
      maintenance plans and schedules will be supplied by CSC Healthcare Systems
      and executed by Customer to provide continued coverage.

      OPERATE CORRECTLY WITH DATES ON AND AFTER JANUARY 1, 2000.

      supported under this plan, unless otherwise specified by CSC Healthcare
      Systems at the time of license.

      by Customer modification, or when a CSC Healthcare Systems program
      correction affects Customer modified code is not covered by this plan.

Periodically, CSC Healthcare Systems will provide program corrections and
enhancements to our Customer base. It is requested that Customers load all
updates within thirty (30) days to expedite account synchronization. CSC
Healthcare Systems suggests that all updates first be loaded to a test account

successful evaluation, the program(s) may be loaded by the Customer to live
production accounts.

It is the direct responsibility of the Customer to maintain account
synchronization with CSC Healthcare Systems. Failure to load CSC Healthcare
Systems updates within the requested 30 day time frame will affect the ability
of the Customer to load future program updates as well as the ability of CSC
Healthcare Systems to provide quality support services on a timely basis. As
such, requests made of the CSC Healthcare Systems Customer Service Center
pertaining to situations contrary to the above policies, will be deemed billable
on a time and materials basis at the prevailing hourly rate. Customer
authorization will be requested before billable services are provided. In such
cases, CSC Healthcare Systems will request Customer authorization via an
executed Change Control Notice (CCN), before providing billable services.

The following guidelines will help your Application Support Analyst resolve
issues as quickly as possible. When placing your request:

      Please provide as much information as possible about the problem or
      question you have. Facts such as the program number, related error
      messages, unusual circumstances, and the exact sequence of events that
      led to your situation will all help your Application Support Analyst to
      resolve your problem or question in a timely, efficient manner.

      Per the standard license contract, one primary and one backup person
      should be designated by the Customer to act as contact points for CSC
      Healthcare Systems personnel. Ideally, these individuals will have
      attended the complete series of application software training courses
      offered by CSC Healthcare Systems.

      Additional printed information pertaining to your request should be sent
      via facsimile to your Application Support Analyst.__. The Customer Service
      Center facsimile number is:

      If you find it necessary to contact your Application Support Analyst about
      an open request, please call 1-800-553-2722.

      To ensure rapid response and proper tracking of your requests, we strongly
      recommend that you do not attempt to log new requests via fax or voice
      mail. Your cooperation in this matter will help us to maintain our
      response standards and to provide you with the best possible service.

      If an Application Support Analyst leaves a message or requests information
      on three consecutive days and does not receive a response from the
      Customer, the case will be closed. If additional assistance is required
      after closure, Customer will be required to open a new case.

      execution of this Agreement, source code escrow fees charged by Fort Knox
      Security are $100 per deposit or update.

5.    Add Section 4.1.4 as follows:

      "For purposes of Sections 4.1.1 and 4.4.1, the term CUSTOMER shall mean

      CUSTOMER. CSC Healthcare Systems further acknowledges that CUSTOMER treats
      its confidential information as confidential, and CSC Healthcare Systems
      agrees to use all reasonable efforts to confine knowledge and use of the
      confidential information solely to its employees who require such
      knowledge and use thereof in furtherance of this Agreement for the benefit
      of CUSTOMER. CSC Healthcare Systems shall not disclose or permit access to
      such confidential information by any third party without the prior written
      consent of CUSTOMER. CSC Healthcare Systems shall have no obligation to
      preserve the confidentiality of any information which (a) was previously
      known to it free of any obligation to keep it confidential; (b) is or
      becomes publicly available, by other than an authorized disclosure; (c) is
      independently developed by CSC Healthcare Systems without knowledge of
      CUSTOMER's confidential information; (d) is disclosed to CSC Healthcare
      Systems by third parties without restriction; or (e) is required by law to
      be disclosed. CSC Healthcare Systems agrees that the unauthorized use,
      disclosure, or transfer of CUSTOMER's confidential information will
      diminish substantially its value to CUSTOMER, and, if CSC Healthcare
      Systems breaches any of its obligations set forth in this Section 4.4.4,
      that CUSTOMER shall be entitled to equitable relief including orders for
      injunction as well as monetary damages."

      CUSTOMER to continue use of the Programs for the term of this Agreement
      and pay for any additional fee required for such license; (ii) modify the
      Programs to avoid the infringement or (iii) replace the Programs, without
      additional charge, with a compatible functionally equivalent and non
      infringing product."

9.    Travel expenses billed to CUSTOMER shall be billable in accordance with
      the Travel Policy attached hereto as Exhibit A.

10.   Section 7.6.1 is deleted and replaced with the following:

      or in part by CUSTOMER upon notice to CSC Healthcare Systems, whenever,
      for any reason, CUSTOMER shall determine that such termination is in its
      best interests. To be effective, such notice must be in writing and
      rendered to CSC Healthcare Systems at least five (5) business days prior
      to the date of termination.

      employment to, or otherwise directly or indirectly use the services of any
      employee or any former employee of the other party for a period of six (6)
      months after termination of such employment, nor shall CUSTOMER employ any
      prospective employee of CSC Healthcare Systems who has been introduced to
      or interviewed by CUSTOMER through the services of CSC Healthcare Systems
      within six (6) months of that introduction or interview. The hiring fee
      shall be equal to 30% of the gross salary to be paid by the other party to

This Schedule is governed by the terms and conditions of Agreement number
20206 between CSC Healthcare Systems and Healthnet Management, Inc.

      1.    To the extent that the provisions of this Schedule K03 conflict with
            the Agreement, the provisions of this Schedule K03 shall control.
            CUSTOMER agrees to keep confidential all terms and conditions of
            this Schedule K03 and any other present and future non-standard
            contract terms, and shall require all of its agents and
            representatives to observe this confidentiality provision.

      2.    Application Response Time (Schedules B14, C07 and E08)

            Every implementation of MHC Program applications is in a unique
            environment subject to user and data volumes that vary by location,
            time of year and even time of day. CSC Healthcare Systems estimates
            the application response time for the average RS/6000 model J40
            family system to be 2.5 seconds or less within program groups
            non-processing activities while changing screens for an average
            member processing of approximately 145,000 members.

            If the 2.5 second response time estimate, as further defined below,
            is not met as measured by the below response measurement process at
            any point within one (1) year of the Effective Date of this Schedule
            K03, the same shall not constitute an event of default under the
            Agreement, but rather as CUSTOMER's sole and exclusive remedy CSC
            Healthcare Systems will correct the condition at no charge to
            CUSTOMER, provided CUSTOMER notifies CSC Healthcare Systems in
            writing that the 2.5 second response time has not been met and
            provided such condition is not due to the fault of CUSTOMER. If due
            to the fault of CUSTOMER, the correction of the condition and
            related services, including CSC Healthcare Systems' analysis, shall
            be at CUSTOMER's expense.

            This response time estimate shall apply only to the Release 14
            Program upgrade under Schedule E08 installed in an environment
            consisting of an IBM RS 6000 Model J40 System in the configuration
            under Schedule B14, and including AIX (Schedule C07), uniVerse,

                                  SCHEDULE K

                           SPECIAL CONSIDERATIONS

This Schedule is governed by the terms and conditions of Agreement number
20206 between CSC Healthcare Systems and Healthnet Management, Inc.

            * Quarterly uniVerse database File Statistic Reports consisting of a
            "pre-maintenance" File Statistic Report and a corresponding,
            "post-maintenance" file resizing File Statistic Report.

            * Internal I/T Help Desk Service Call Logs with corresponding call
            closing resolution data.

      The above information shall cover the date of hardware installation
      through the date of CUSTOMER's written notification to CSC Healthcare
      Systems that the 2.5 second response time has not been met.

      Response measurements shall be subject to the following process:

      a. Within one (1) month of live operations of the System for a single line
      of business, CUSTOMER and CSC Healthcare Systems will jointly certify the
      2.5 second response time for the System configuration, as well as System
      file status, for measurement sampling purposes.

      b. Response time interval shall be measured by CUSTOMER with a stopwatch,
      using a representative non-batch processing MHC Program agreed to by CSC
      Healthcare Systems, starting when the "enter" key is depressed and ending
      when the last return character is painted to the screen. Each of these
      measurements shall be one (1) response time sample. If CUSTOMER provides
      written notification to CSC Healthcare Systems that the 2.5 second
      response time has not been met, CUSTOMER'S measurements must be verified
      or duplicated by CSC Healthcare Systems. Upon such verification or
      duplication, CUSTOMER and CSC Healthcare Systems will mutually agree upon
      the corrective action to be taken.

                             SPECIAL CONSIDERATIONS

This Schedule is governed by the terms and conditions of Agreement number
20206 between CSC Healthcare Systems and Healthnet Management, Inc.

      c. Response time sampling, using the same non-batch processing screen,
      shall be performed two to three (2-3) times weekly over a one (1) month
      sample measurement period ("Sampling Period"), collecting a minimum of
      twelve (12) samples during the Sampling Period. Ninety percent (90%) of
      these samples (11 samples) must meet the 2.5 second response time
      estimate.

      d. Sampling shall be performed during the day shift when only non-batch
      processing MHC Programs are running on the System and will be scheduled to
      minimize the performance degradation caused by simultaneous batch jobs
      running in the background. Monthly and batch processing are excluded from
      the Sampling Period since simultaneous batch jobs are typically required
      during the close. Ad hoc reporting is also excluded from the Sampling
      Period. Sampling Period schedules shall be mutually agreed to between CSC
      Healthcare Systems and CUSTOMER.

      e. The results of each Sampling Period will be charted by CUSTOMER and
      reported to CSC Healthcare Systems. CSC Healthcare Systems and CUSTOMER
      will jointly review the results each quarter, identify adverse response
      time trends, and plan corrective measures.

      f. All sampling shall be performed with direct connect terminals or
      terminals not connected through CUSTOMER's network.

                             SPECIAL CONSIDERATIONS

This Schedule is governed by the terms and conditions of Agreement number 20206
between CSC Healthcare, Inc. and HealthSpring Management, Inc.

1.    To the extent that the provisions of this Schedule K07 conflict with the
      Agreement the provisions of this Schedule K07 shall control. CUSTOMER
      agrees to keep confidential all terms and conditions of this Schedule K07
      and any other present and future non-standard contract terms and shall
      require all of its agents and representatives to observe this
      confidentiality provision.

2.    This Schedule K07 is issued to reflect the conversion of the user-based
      Program license (MHC, CAP and MRM) as set forth in Schedule 20206.D14 to
      the membership-based Program license set forth in Schedule 20206,D18
      hereto. Such conversion does not apply to SBRuntime, SBDeveloper,
      HostAccess and UniVerse.

3.    Section 1.10 is added as follows:

      Member Live(s) - Those individuals who are actively enrolled in a health
      plan administered by the CUSTOMER.

4.    The following Section 4.1.5 shall apply to Member Lives-based Programs:

      (a)   CSC Healthcare hereby grants to CUSTOMER, a perpetual, limited,
            non-exclusive license for use of the Programs. Such license shall be
            subject to the following privileges, limitations and conditions, and
            to the limitations and conditions contained elsewhere in this
            Agreement:

            (1)   The Programs are restricted, as indicated in Schedule D
                  hereto, by the number of Member Lives which may be processed
                  using the Programs.

            (2)   CUSTOMER shall grant CSC Healthcare the right to access
                  CUSTOMER's system on an annual basis to perform a membership
                  audit. CUSTOMER may exceed the number of Member Lives
                  originally licensed provided CUSTOMER has permitted CSC
                  Healthcare to perform an annual membership audit. If Member
                  Lives decrease below the number of Member Lives for which
                  CUSTOMER has paid the applicable license fees, the number of
                  Member Lives may increase again, up to the level for which
                  CUSTOMER has previously paid, without further payment
                  obligations until such time as CUSTOMER exceeds the number of
                  Member Lives for which license fees have been paid.

            (3)   MHC license billing will occur on an annual basis if there is
                  an increase in membership of 5,000 members or more since the
                  most recent billed membership count on the annual membership
                  count. In the event that CUSTOMER's membership increases above
                  the number of licensed Member Lives under this Agreement,
                  CUSTOMER shall execute an amended Schedule D and pay any
                  additional charges in effect at the time such order is placed.

Dear MHC client:

THANK YOU FOR BEING A CSC HEALTHCARE GROUP CUSTOMER!

As you know, CSC has extended support and maintenance for MHC Release 14.4
beyond the projected availability date of Release 16.0, however, support will
end on December 31,2000.I am pleased to present to you an update on our progress
with MHC Release 16's base functionality and to respond to your requests for a
program to fast-forward the development of MHC by incorporating a substantial
number of your custom modifications into the standard MHC package. This could
enable you to upgrade to MHC Release 16.2 and enjoy the many advantages of our
standardized development strategy.

MHC has a long and successful history as a multi-faceted managed care
information system, and until recently, has embraced the concept of custom
modifications. You have told us that, while customizing your copy of the
software solves short-term problems efficiently, it creates huge operational and
financial barriers to upgrading to new releases of our software. As a result of
your input, we introduced the concept of standard software releases, thereby
making all new development available to all clients. With MHC Release 15, we saw
seven clients embrace the standardized concept and these clients are now
positioned to upgrade quickly and inexpensively. Because of the time pressures
brought about by the year 2000 computer issue, and because many of your custom
enhancements were not included in Release 15, many of you chose to upgrade to
Release 14.4 and retrofit your custom enhancements (at a high cost).

BASE MHC RELEASE 16.0

First, an update on the progress of Base MHC Release 16.0. As you know, a
portion of your monthly maintenance payment is allocated to fund new releases of
MHC. With Release 16.0, CSC has matched your contribution to build a total of
15,000 hours of new functionality. The Base Release 16.0 functionality focuses
on provider contracting and will greatly increase your flexibility in managing
contracts. As promised, we are on schedule to finish MHC Release 16.0 in March
of 2000. (See tab 1 "MHC Base Release 16" for details on the functionality and
development status).

MHC RELEASE 16.2 ENHANCEMENT PACKAGE PROGRAM

Based on your feedback, we have also designed a program with which an additional
20,000 hours of functionality can be funded into Release 16.2 and could be ready
as soon as summer of 20001 Depending on your participation, and the
participation of other customers, approximately $2,670,000 of software
development could be directly incorporated into standard MHC Release 16.2. Most
of your current customization could then become standard in the MHC package,
allowing you to move forward and join our Release 15 clients who enjoy the
benefits of easy upgrades, rapid software development, and faster availability
of new software modules. (See tab 2 "Joint Funding Packages" for details on the
contents of the optional enhancement packages).

<PAGE>

HERE IS WHAT THE ENHANCEMENT PACKAGE PROGRAM COULD PROVIDE

The total cost of the enhancement package being considered by CSC is
approximately $2,700,000. It would include enhanced functionality in the
following areas:

Based on our preliminary calculations, if 20 clients participate in the funding
of the Enhancement Package, each client would need to pay $108,000 in order to
receive $2,666,950 in functionality. TO DEMONSTRATE OUR DESIRE TO CONTRIBUTE TO
THE FAST TRACK DEVELOPMENT OF MHC AND TO HELP DEVELOP THE ENHANCEMENT PACKAGE
PROGRAM, CSC WOULD CONTRIBUTE THE FIRST $500,000 TOWARD THE ENHANCEMENTS. Of
course, CSC needs significant client participation in order to turn this vision
into reality. In order to gage client interest, CSC is asking prospective
participants of the Enhancement Package to affirm their interest by: (1) signing
this letter, (2) returning it to CSC, and (3) enclosing a $10,000 refundable
deposit along with the signed letter. This is a new innovative approach to
determine if there is support in the marketplace for the standardized
functionality contained in the Enhancement Package. CSC will not go forward with
this effort unless at least 20 clients participate and ultimately execute
binding contractual agreements.

For participants using MHC Release 14.4, CSC would be prepared to lock in a
fixed price for upgrade services into a contract for the Enhancement Package
Program. This Program feature would thus allow you to budget for the cost of
moving to the standard MHC release in the year 2000. This package would contain
services for a basic upgrade to Release 16.2, but would not include the retrofit
and standardization of modifications, which are not in the enhancement package.

HERE ARE THE ADVANTAGES TO SIGNING UP NOW FOR THE ENHANCEMENT PACKAGES AND
PAYING THE REFUNDABLE $10,000 DEPOSIT

-    You would receive priority in upgrading to Release 16.2 if CSC ultimately
     to decide to go forward with the Enhancement Package

-    You would help CSC's efforts to make the Enhancement Package a reality

-    You are not risking anything, because the deposit is refundable until a
     binding contact is executed

HERE ARE SOME VERY SIGNIFICANT ADVANTAGES YOU COULD RECEIVE AFTER A CONTRACT IS
EXECUTED FOR THE ENHANCEMENT PACKAGES

-    Your monthly support and maintenance charges will not increase until at
     least January 1st, 2001

-    You will receive a fixed price on upgrade services

-    You will guarantee a reduced rate of $100 per hour on any programming
     services until the completion of MHC Release 16.2, in the event you need
     short term work done

-    You pay no support and maintenance on the enhancement functionality once
     upgraded to Release 16.2

-    By making MHC a better product that allows you to upgrade regularly and
     easily, you create the critical mass of standard release clients that will
     enable faster, less expensive development of future MHC releases

<PAGE>

HERE ARE SOME IMPORTANT FACTS FOR YOUR CONSIDERATION

-    The $10,000 deposit would be refundable at your request until a binding
     contract can be executed. Similarly, CSC is not legally bound by this
     letter until a valid contract can be executed.

-    In order to expedite development of the Enhancement Packages, CSC would
     have complete control over design and programming decisions.

-    CSC's ability and desire to go forward will be largely based on your
     response, and the responses of other potential participants.

We will contact each of you in the next two weeks to discuss this exciting
opportunity. We have a limited window of time to accomplish participation and
complete programming so we have set a date of September 10th to receive all
signed responses and deposits. Please sign and return this letter if you wish to
further investigate this opportunity.

Please review all of the information in this package and call me at
(248)372-3261 if you have any questions.

Sincerely,

Douglas S. Coleman
Senior Sales Executive
CSC Healthcare Group

No legal obligation is created by signing this letter. Signing this letter
merely affirms your interest in potentially participating in the Enhancement
Package Program and payment of the $ 10,000 refundable deposit.

     Dear Ms Timko:

     SUBJECT: Enhancement Package Program

     Thank you for your commitment to the MHC product. We want you to know that
     we share that commitment to further strengthen your product

     The purpose of this letter is to secure your participation in the
     Enhancement Package Program as a means to advance your MHC product. THE
     TIME TO ACT IS NOW -- OTHERWISE, YOU WILL COMPROMISE YOUR ABILITY TO USE
     MHC BEYOND DECEMBER 2000.

     SPECIFICALLY, YOU MAY EITHER:

     -    SUBSCRIBE TO THE ENHANCEMENT PACKAGE PROGRAM (DESCRIBED BELOW) AND
          ENJOY A MORE ROBUST MHC. By doing so, you will secure additional
          benefits, including deferral of major investments until 2001.

          OR

     -    UPGRADE TO RELEASE 15 OR 16, BY THE END OF CALENDAR YEAR 2000, PAYING
          FULL PRODUCT SUPPORT RATES TO RETROFIT YOUR CUSTOM MODIFICATIONS INTO
          A STANDARDIZED FORMAT. These modifications will cost more than
          traditional upgrades in the past.

     MHC customers face this clear-cut choice now because SUPPORT/MAINTENANCE
     FOR RELEASE 14.4 WILL END ON DEC. 31, 2000, EXCEPT FOR SUBSCRIBERS TO THE
     ENHANCEMENT PACKAGE PROGRAM. Clients who are no longer covered by
     support/maintenance will not only lose support for software and custom
     modifications, but will also lose eligibility for future releases. (See
     detailed explanation below.)

     MHC customers are strongly encouraged to subscribe to the Enhancement
     Package Program because your participation:

1.   Supports the future vision for MHC to meet your system needs for the
     long-term;

2.   Creates a predictable plan for future release timing and release-specific
     support/maintenance that will deliver an increasingly robust MHC;

3.   Embarks on making standardization and joint-funding a reality;

4.   Leverages a highly attractive CSC proposal for joint-funding through the
     Enhancement Package Program; and,

5.   Secures for you a uniquely attractive set of incentives.

Please see the attachments for details on each of the above sections, as well as
the attached Contract Schedule F for your signature.

We're excited about the future of the MHC product and in partnering with you to
make sure that it continues to meet your needs. We intend to actively market MHC
to new clients to spread the cost of development. We're working hard to improve
customer service/support. And finally, we're committed to reach out to every
client to re-establish strong relationships -- to insure mutual benefits from a
strong MHC product. We look forward to hearing from you by Oct. 29, 1999 about
whether you will subscribe to the Enhancement Program Plan, or upgrade to
Release 15 or 16. A member of our team will be following up with you next week
to see if you have any additional questions.

Sincerely yours,

1. Future Vision: Meets Your System Needs for the Long-Term

To ensure MHC's affordability, CSC is consolidating all of its MHC clients onto
no more than two concurrent releases. At present, 8 clients enjoy the benefits
of standardization on Release 15. However, over 40 clients use MHC Release 14.4,
each customized to varying degrees. This multitude of customization creates
costly development, support/maintenance and upgrades/retrofits to new releases.
You have told us you cannot continue to upgrade MHC and pay each time to
reprogram your custom modifications. Hence, this move to standardization.

To meet your long-term system needs, MHC will provide software that offers a low
cost of operation, while meeting critical functional and regulatory needs. Low
cost of operations will be achieved by standardizing the software, thereby
facilitating superior support/maintenance and lowering the cost and difficulty
of upgrades. Furthermore, we will continue to provide a "character-based" claims
entry screen for efficient data processing, while enhancing the front end for
your clients, providers and members, through web enablement. This web option
should be available before year-end. In addition, we will work with you over
time to improve MHC's claims throughput and other core processes.

To achieve these goals, we--CSC and you, our MHC customers--have agreed to a
strategy that involves aggressive and consistent interaction and mutual
commitment. Called "joint funding," this strategy integrates two elements:
using part of your support/maintenance payments for development and
client-funding for enhanced functionality. While CSC will allow MHC clients to
bring forward their unique custom modifications--in standardized format--we
will emphasize client joint-funding for standardization to reduce costs to
individual clients.

2. RELEASE TIMING AND SUPPORT/MAINTENANCE: PROVIDES PREDICTABLE TIMELINES
AND AN INCREASINGLY ROBUST MHC

Each March, CSC plans to deliver a major MHC release containing
improvements in functionality and ease of operation. In between, maintenance
releases for corrections and ongoing compliance issues will be delivered.
Therefore, in March, 2000, Release 16 is scheduled to be available; that release
will accommodate client-specific, upgraded custom modifications in standardized
form only. In March, 2001, CSC plans to offer Release 17, which will target
HIPAA compliance, greater e-commerce capability and higher claims throughput.
With your funding participation, MHC will deliver the Enhancement Package
Program functionality as part of Release 17.

The corresponding support/maintenance policy is that MHC will support only
two releases simultaneously, the current, release and the most recent prior
release. For example, when Release 17.0 becomes available support/maintenance
will be limited to Release 16 and Release 17. Therefore, MHC clients must keep
current or lose support/maintenance.

In recognition of the unique situation created by Y2K, however, MHC is
adjusting this policy on a one-time basis. Specifically, MHC has extended
support/maintenance for Release 14.4 until December 31, 2000. Once Release 16.0
becomes available and December 31, 2000 has passed, support/maintenance for
Release 14.4 will be discontinued, except for Subscribers to the Enhancement
Package Program, with the consequence of loss of eligibility for access to new
releases of MHC.

3. ENHANCEMENT PACKAGE PROGRAM: EMBARKS ON THE STRATEGY OF STANDARDIZATION-AND
JOINT-FUNDING

As described in Future Vision, joint funding is designed to include client
funding for packages of common modifications; therefore; groups of clients can
come together to standardize these packages at a leveraged cost, rather than
individually. Standardization of these packages will enhance MHC's functionality
in the standard form, and the HUG Board and members will select the
functionalities.

In the case of the current initiative, the Enhancement Package Program
contents, selected for the first wave of "joint funding" include six elements;
enhanced claims processing (such as flexible duplicate claims checking, timely
claim filing flags, suspend claims at employer level, interim claim processing,
using all diagnosis codes, automatic recalculation of adjusted claim lines,
non-vendor PCP capacity), data capture/reporting, provider assignment, benefits
enhancements, inquiry/look up, and open auths/pre-certs. Collectively,
standardization of these custom modifications will cost $2.7MM. By "joint
funding" this investment, all who Subscribe to the Enhancement Package Program
will enjoy the benefits of $2.7MM in standard modules, at a fraction of their
cost.

4. SUBSCRIPTION: LEVERAGES A HIGHLY ATTRACTIVE APPROACH TO JOINT FUNDING

All MHC clients are invited to subscribe, at a fixed cost, to the defined
Enhancement Package Program; note that the scope of the Enhancement Package
Program is locked, based on previously-made HUG selections. To demonstrate its
commitment to MHC, CSC is ready to commit $500K to this effort, based on at
least 20 Subscriptions (out of a total MHC client base of about 40). If more
than 20 clients elect to participate through the end of the implementation
process, CSC will share those additional subscription fees with the Subscribers
on a pro-rata basis at the end of the project. Furthermore, CSC will cap the
development costs per client at $108K, and will return any funds not used in
Enhancement Package Program development.

To initiate this effort, CSC seeks signed contracts and the $10K deposits
for the Subscription by October 29, 1999. To insure rapid, delivery of the
Enhancement Package Program, CSC will conduct the development. Subscribers must
pay their $108K by January 14, 2000. You will begin to receive the
specifications (problem statement, approach to programming and high-level
description of functionality) for review by March 8, 2000. Subscribers will
retain the right to opt out of the Subscription Program -- as an option that may
be available -- as late as March 15, 2000.

For clients on Release 14.4, Subscriptions will cost $108K (exclusive of
the upgrade costs). Clients on Release 15, as well as REP clients, are invited
to timely subscribe for $50K (exclusive of the upgrade costs); Any subscription
contract received after the October 29, 1999 date will cost $250K. All
Subscribers will receive the benefits described below (see Incentives for
Subscription).

                                   [CSC LOGO]

5. INCENTIVES: PROVIDES MULTIPLE BENEFITS TO SUBSCRIBERS

The incentives for Subscription -- available only to Subscribers--include:

- SUPPORT/MAINTENANCE CONTINUATION, for Release 14.4, beyond December 31, 2000,
  until you are actually upgraded (but no later than December 31, 2001)

- SHORT-TERM GAIN SHARING, relative to Enhancement Package Program, such that:

  -    Late subscribers' fees in excess of the base 20 clients required for
       the Program will be split 50:50 between CSC and the Charter
       Subscribers (who will divide their share on a pro-rata basis.

  -    Cost underage will be returned fully to Subscribers (including late
       subscribers) on a pro-rata-basis.

  -    CSC accepts full risk for cost overages as consideration for ultimate
       control over the change control process.

- UPGRADE PRIORITY FOR RELEASE 16 implementations, which materially advances
  the timeframe within which Subscribers will be able to use this
  functionality; in addition, MHC will publish and guarantee delivery dates
  for the packages

- FIXED PRICE UPGRADE SERVICES will be offered to Subscribers, after detailed
  (client-specific) analyses are conducted after the release of 16.0 (March,
  2000); this analysis will cost $10K, which will be applied to ultimate
  upgrade costs. The upgrade process includes:

  -    Implementation and data conversion

  -    Integrated consulting, project management and training

- Upgrades of non-standard enhancements (modules)

- A FREEZE ON MONTHLY MHC SUPPORT & MAINTENANCE FEES will be guaranteed
  through December, 2000, with Subscribers thereby avoiding the increase in
  monthly payments planned for January, 2000; note that any new custom
  modifications will still require additional support & maintenance fees

- REDUCED PS RATES, at $100/hour on any ad hoc modification work needed until
  the Release becomes available

- OPTION TO AVOID SIGNIFICANT CAPITAL EXPENSES IN 2000, because you may defer
  upgrading to Release 17 until calendar year 2001; whereas, other option --
  upgrading to Release 15 or 16 -- would need to be complete by December 31,
  2000 to continue your use of MHC.

As always, you may contract with CSC to have your custom modifications made
part of standard MHC on a time and materials basis at CSC's standard development
rates of $175/hour for design and $130/hour for programming -- except for
Subscribers who will receive the preferred rate of $100/hour for upgrading
custom modifications to release 16 or 17. Alternatively, and we believe
preferably, you can Subscribe to the Enhancement Package Program and receive the
above advantages. In addition, we offer a $10K contract to prepare a proposal
for your upgrade. Note that this $10K proposal contract is not the same as the
$10K deposit for the Subscription. MHC will commit to this proposal as a fixed
price for the project and will apply your $10K to the overall upgrade cost
(which includes the proposal development).

RE: Notice of Assignment of License and Services Agreements for Ardent
Software Products ("Existing Agreements")

Dear Customer:

On November 30, 1999, Ardent Software, Inc. ("Ardent"), and Informix
Corporation ("Informix"), signed a definitive Agreement and Plan of
Reorganization ("Agreement") under which Informix would acquire all of the
outstanding stock of Ardent pursuant to the merger of a wholly-owned subsidiary
of Informix with and into Ardent ("Merger"). Ardent will continue to exist for
a period of time after the Merger as a wholly-owned subsidiary of Informix. The
Merger will combine the resources of the companies together with complementary
technologies and other associated products.

Informix's headquarters are located at 4100 Bohannon Drive, Menlo Park,
California 94025. The Merger was completed on March 1, 2000.

As a result of this Merger, the aforementioned Existing Agreements have
been assigned to and assumed by Informix Software, Inc. a wholly-owned
subsidiary of Informix Corporation, as of March 1, 2000:

Your sales representative will soon be in touch with you and/or other
employees of your company to discuss any matters relating to the Merger.

                                           Very truly yours,

                           FOCAL POINT IMPLEMENTATION

The implementation of the Focal Point Decision Support System will be
accomplished in five Implementation Visits over an approximate period of four
months. Prior to the first site visit, the customer shall be responsible for
certain items which will ensure a correct environment for the Focal Point
system. These items include the purchase and/or designation of a database
server, per CSCHS' recommended configuration, which should be used for Focal
Point. If a network interface is involved, the proper communication between the
server and the network should be tested. A Database Management System (DBMS) is
another requirement for the operation of Focal Point. These requirements will be
discussed in more detail at site visit #1.

Implementation Visit #1 involves a formal kickoff meeting and operational
review. The kickoff meeting includes a detailed demonstration of the Focal Point
DSS. The target audience for the kickoff meeting should be the business users of
the system, the MIS department, and others interested in the capabilities of
Focal Point. After the demo, discussions of the business practices of the health
plan will occur over the remaining time. During this visit, the Focal Point
consultant will interview representatives from the various departments to better
understand their business operations and to ensure that the data captured with
Focal Point is interpreted correctly. Interviews may also take place with key
decision makers in the health plan to develop a strategy for effective use of
the DSS. Finally, a sample of claims and membership data may be requested so
that the data can be examined by the Focal Point consultant in Southfield,
Michigan.

The actual system installation occurs at the next visit (Implementation
Visit #2). This generally will take place six to eight weeks after the
operational review. In the weeks preceding the visit, a technical consultant
will work with the customer on the technical requirements to operate Focal
Point, as it is necessary for the correct environment to be in place before the
visit. During this visit the technical consultant will build the Focal Point
database. The building of the database involves extracting the data from the
on-line claims system as well as populating the data tables. The visit can last
up to four days with the technical consultant working largely independent of the
customer's MIS staff.

Implementation Visit #3 will occur three to four weeks after the
installation of the system. This visit involves training sessions conducted at
the client site by the Focal Point consultant. Three separate training sessions
will take place over the course of three days. A training session for the
business users of Focal Point will last approximately one and one-half days.
This is geared for those who will be integrating Focal Point in their business
practice for use as a decision support tool. The next day will focus on training
the MIS staff, or those who will support Focal point internally. Finally, an
overview session will last one-half day. This session is aimed at anyone else in
the organization who wants to know the capabilities of the system.

Implementation Visit #4 will occur at the first month-end following the
training described above. This visit is performed by the technical consultant
and is geared towards two objectives. The first objective involves extracting
supplemental information from the transaction processing system and building
onto the existing database. Secondly, additional technical training is provided
to the MIS staff on the maintenance of the database and future supplemental
runs.

Implementation Visit #5 will occur 4-6 weeks after visit #4. The purpose
of this visit is to provide follow-up training to the end users and technical
users of Focal Point. Additionally, the consultant will provide guidance on how
the information from the Focal Point system can be integrated into the overall
business objectives of the organization.

On-going user support and technical support for year one of the three-year
agreement is included in the Focal Point contract. Support from the consultants
or support representative via telephone is included, as well as on-site when
appropriate. Additional consultation, on a time and materials basis, is also
available when the customer needs to develop new types of reports, data
perspectives, or extracts.

If the system includes the Johns Hopkins ACG Case-Mix System then additional
training and consulting will be provided for the Physicians Profiling with ACG's
module.
