                               AMENDMENT NUMBER 1
                                       TO
                   INFORMATION TECHNOLOGY SERVICES AGREEMENT

This is Amendment Number 1, dated as of September 15, 1997 to the Information
Technology Services Agreement (the "Agreement") dated as of June 1, 1996
between UNISYS CORPORATION ("Unisys") and UNITED HEALTHCARE SERVICES, INC.
("UHS").

Section 3.18 of the Agreement provides that the Parties will jointly develop
and implement a revised charge process in accordance with Exhibit 31 of the
Agreement which will result in charges based on the usage of computing resources

ACCORDINGLY, in consideration of the premises and other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged,
Unisys and UHS hereby agree to amend Exhibit 31 of the Agreement to incorporate
the following additional provisions:

     1. Rate Card. Attached hereto as Exhibit 31-1 is the rate card which sets
     forth the methodology by which UHS will be assessed charges for Services
     provided by Unisys pursuant to the Agreement.

     2. UNIX charges by system. Attached hereto as Exhibit 31-2 are schedules
     containing the charges for the initial systems and systems added during
     1996. The initial systems listed by serial number in Exhibit 2 of this
     contract amendment replace those listed in Exhibit 6 of the Agreement.

     3. Methodology. Attached hereto as Exhibit 31-3 is the methodology and
     description forming the basis for the application of the Rate Card.

     4. Effective Date. The rate card is effective January 1, 1997. Within 30
     days of execution of this Amendment Number 1, Unisys will provide to UHS
     retro-active rate card based invoices and credits to reverse prior Interim
     Agreement charges.

     5. IBM consumption based charges. Consumption based charges will be
     developed including prime and off-prime rates. The rate card for these
     charges will have a structure similar to the Unisys rate card. The goal is
     to have these charges be effective October 1, 1997. Should the rate card
     not be finalized by October 1, Unisys will continue charges based on
     capacity, with the understanding that these charges will be reversed and
     replaced by consumption based charges retro-active to October 1, 1997.

                                       TO
                   INFORMATION TECHNOLOGY SERVICES AGREEMENT

     6. UNIT/NT consumption based charges. The Account Executives will review
     the possibility of converting UNIX/NT to consumption based charges. A
     feasibility study will be submitted to UHS by January 1, 1998. Effective in
     1998, a report on the status of this conversion will be prepared by the
     Account Executives and submitted to UHS on a quarterly basis. Key to making
     this conversion will be the proliferation of large capacity servers with
     the ability to consolidate servers and support consumption measurement
     software.

     7. Prime and off-prime for Unisys. Effective with the 4th quarter of 1997,
     the Account Executives will review this issue on a quarterly basis. The
     Account Executives will consider modifying the rate card for prime and
     off-prime rates, add-hoc requests and/or monthly cyclical rates. A joint
     Unisys/UHS feasibility study will be generated at the request of the
     Account Executives

     8. Per member per month. The Account Executives will consider modifying the
     rate card to per member per month rates.  With mutual agreement, a joint
     Unisys/UHS feasibility study will be generated at the request of the
     Account Executives.

     9. Other Terms. Except as herein specifically amended, all of the terms of
     the Agreement remain in full force and effect and are hereby ratified and
     confirmed. To the extent the terms of this Amendment Number 1 conflict with
     the existing Exhibit 31 or other terms of the Agreement, the provisions set
     forth in this amendment shall control.

IN WITNESS WHEREOF, Unisys and UHS have executed this Amendment Number 1,
effective as of the date first above written.

UNISYS CORPORATION                      UNITED HEALTHCARE SERVICES, INC.

                         BASE CHANGES - VOLUME AND RATE

If the actual unit volume consumed for a specific category exceeds or falls
below the base by 40% or more for three consecutive months, the Account
Executives shall negotiate an adjustment to the base volume and base rate. The
principles underlying this adjustment would be that the adjusted base volume
would not exceed the prior 90 day average volume and the adjusted base rate
would not exceed the prior 90 day unit average.

If the actual unit volume for three consecutive months is 0 and the forecast for
the next 3 months is also 0, the base volume for that particular metric will be
set at 0.

                              VOLUME DISCOUNT RATES

The volume discount percentages apply only to the units in the range for that
particular percentage. For example, if the actual volume is 114% of the base,
the units below 100% receive no discount, the units between 100 - 105% receive
6%, the units between 105 - 110% receive 10% and the units between 100 - 115%
receive 15%.

                   CREDITS FOR UNUSED UNITS BELOW BASE VOLUME

Credits for unused units below the base volume will be granted only for unused
units that have been forecasted. No credits be given for unused units below the
forecast. For example, if the forecasted volume is 75% of the base and the
actual volume is 65% of the base, then credits for the unused units between 75%
and 100% of the base volume will be granted per the schedule. No credits will be
given for units between 65% and 75%. However, if in the same example the actual
volume is 80%, credits are granted for the units between 80% and 100%.

If the volume consumed for a category falls below the base, then the amount
billed will equal the base units times the base rate for that period with a
credit for each unused unit below the base, providing the forecasted volume was
below the actual volume. The amount of the credit is a percentage of the base
rate to be determined according to the rate card schedule.

                                 MINIMUM CHARGES
ALL PERIODS
If the base volume falls below 60% of the initial base volume for a particular
category, for example "Unisys CPU Hour" and the UHS volume forecast for that
category is flat or projecting continued decline, the Account Executives for
Unisys and UHS will jointly agree on a revised rate card for that category as
well as a one-time charge for the reduced capacity requirement, or if UHS
reassigns the volume of one product family (IBM, Unisys, UNIX) to other product
families supported by Unisys, the Account Executives for Unisys and UHS will
jointly agree on an appropriate one-time charge for the eliminated capacity
requirement. This charge will be supported by Unisys and limited to the
remaining Unisys book value of capitalized assets as of the month of termination
less any remaining fair market value of associated equipment, early termination
penalties and/or notice period requirements on hardware and software maintenance
contracts and redeployment costs of affected human resources.

INITIAL 48 MONTHS
Rate Card based charges (Total of Unisys, IBM and UNIX/NT) will not fall below
the "contract to date" values contained in Exhibit 11 of the Agreement.

AFTER MONTH 48

Rate Card based charges (Total of Unisys, IBM and UNIX/NT) will not fall below
the "contract to date" values contained in Exhibit 11 of the agreement.

If UHS reassigns the volume of one product family (IBM, Unisys, UNIX) to another
vendor, the Account Executives for Unisys and UHS will jointly agree on an
appropriate one-time charge for the eliminated capacity requirement. This charge
will be supported by Unisys and limited to the remaining Unisys book value of
capitalized assets as of the month of termination less any remaining fair market
value of associated equipment, early termination penalties and/or notice period
requirements on hardware and software maintenance contracts and redeployment
costs of affected human resources.

The one-time charge referenced above replaces the product family (IBM, Unisys,
UNIX) termination charges contained in Exhibit 17 of the Agreement.

If UHS reassigns the volume of all product families (IBM, Unisys, UNIX/NT) to
another vendor, the Termination Charges from Exhibit 17 of the Agreement are
applicable.

Unisys and UHS agree that the standard depreciation schedule for calculation of
Unisys book value for capitalized assets will be 4 years. Exceptions will be
authorized if both parties agree in advance.

END OF TERM:

BASE SYSTEMS

Effective with January, 1998, Unisys will provide a 90 day notice UHS on systems
reaching the end of their initial term. The initial notification will include
all systems which were fully depreciated by December, 1997. UHS has the option
to terminate, replace, or extend systems at the end of their initial term. If
the system is terminated, Unisys will discontinue charges after the initial
term. If the system is replaced, Unisys will discontinue all capital costs
effective with the end of initial term and discontinue the remaining charges
with deinstallation of the system. If the system is to be extended as
configured, Unisys will submit a new quote for the system without capital costs.

GROWTH SYSTEMS

At 90 days prior to the end of their term as defined in the ASR document, Unisys
will notify UHS of the end of the initial agreement. UHS has the option to
terminate, replace or extend systems after their individual term. If the system
is terminated, Unisys will discontinue all future charges after the initial
term. If the system is replaced, Unisys will discontinue all capital costs
effective with the first month after the initial term and discontinue the
remaining charges with deinstallation of the system. If the system is to be
extended as configured, Unisys will submit a new quote for the system without
capital costs.

EARLY TERMINATION

With a 90 day notice, UHS will be allowed to terminate UNIX systems prior to the
end of their term by paying Unisys an "Early Termination Charge" equal to the
remaining Unisys book value as of the month of termination less any remaining
fair market value.

                                 VOLUME FORECAST

United HealthCare Services will provide Unisys with a 12 month consumption
forecast for all mainframe metrics on a quarterly basis. That forecast will be
delivered on the 15th of the final month of each quarter (March, June, September
and December).

         Missing Viewpoint Data      In the event that Viewpoint data is missing
                                     or corrupted for any given time period
                                     (minute, 15 minute, hour, day, etc.),
                                     Unisys will average the data from the
                                     previous good time period with the
                                     following good time period.  For example,
                                     if 14 minutes of data are missing, Unisys
                                     would average the previous 15 minute sample
                                     with the next 15 minute sample to compute
                                     an average for the missing period.  If 23
                                     hours of data was missing, the previous and
                                     next daily samples would be used to compute
                                     an average.

                                     Unisys would clearly report exactly what
                                     method and samples it used in computing
                                     metrics for any lost period.

Forecasting and Measuring

Forecasting metric to be used      Total Application CPU Hours/Month/Workgroup
                                   (database) forecasted on machine that the
                                   database is running on.(1)
Unit of Measure                    Viewpoint will capture processor utilization
                                   statistics for the various workgroups.  The
                                   utilization statistics for multi-processor
                                   A18's need to be converted into a common
                                   metric (A18- 1x Application CPU hours) for
                                   that class of machine.(2) Different processor
                                   classes (e.g., A19) will require a conversion
                                   factor to produce compatible hourly
                                   projections.  The Relative Performance
                                   Measure (RPM) as reported by Unisys product
                                   specifications will be used to make this
                                   conversion.
How forecasted and measured        Computed and tracked via Viewpoint CPU USER
                                   PERCENT samples
When computed                      Viewpoint will monitor processor usage by
                                   taking snapshots of the usage each minute.
                                   These minutely samples are automatically
                                   consolidated into summary records by
                                   Viewpoint (e.g., 15 minutes, hourly and daily
                                   records).  The daily records will be used in
                                   computing total monthly usage.
What forecasted/measured           A workgroup will be defined for each
                                   database.

                                   For the production machines, one total will
                                   be forecasted for each database plus one
                                   total for "OTHER." OTHER will contain
                                   programs that aren't easily broken out by
                                   database even though their time may be
                                   attributable to a particular database.(3)

                                   For the development machines, one monthly
                                   total for everything will be provided.
What programs are included/        Since UHS has several thousand programs
excluded from forecast             running in production on the various machines
                                   under various usercodes, and the list of
                                   programs change on a frequent basis, an
                                   inclusive list of all programs would be
                                   unmanageable.

                                   Excluded programs are:

                                   (minute, 15 minute, hour, day, etc.), Unisys
                                   will average the data from the previous good

                                   would average the previous 15 minute sample
                                   with the next 15 minute sample to compute an
                                   average for the missing period. If 23 hours
                                   of data are missing, the previous and next
                                   daily samples would be used to compute an
                                   average.

                                   Unisys would clearly report exactly what

BILLING UNITS

Total application CPU hours per month for all A Series machines

MACHINE/RESOURCE UTILIZATION

In general, for an on-line oriented machine, as the machine utilization
approaches saturation, technical support requirements increase exponentially.
Efficient and cost effective computer operations requires executing the hardware
resources at the highest level possible that doesn't require oppressive human
intervention. The billing rates will be based on a best fir of machine
utilization and technical resource utilization.

Conversation Factor

Since a variety of processor speeds/models are in use by UHS and it is expected
that new processor speeds/models will be used, a conversion must be done to
convert application CPU hours on all machines to a common metric. The
conversation factor is the multiplier that will be applied to convert that
machine to A18 - 1x Application CPU hours (the base metric). For example, ***

Machine Style       Conversion Factor

A18 - all models    ***
A16-82L             ***
A19 - all models    ***
NX4801              ***

BILLING REPORTING

Unisys and UHS have defined workgroups into which the Viewpoint data will be
defined. The hours in these workgroups will be converted to a common metric and
summed monthly to provide the total Application CPU hours used. One workgroup
exists for each A Series database plus one workgroup for all applications
("OTHER") that don't easily fit into a database workgroup. Unisys will provide
billing detail at the summarized workgroup level.

DISK FORECASTING/BILLING METRICS

Metric to be used Maximum GB used within month

Unit of Measure   Gigabytes of fault tolerant disk(1)

How computed              The DCOLLECT tool will run multiple times per day
                          capturing the maximum disk used in each of the disk
                          pools plus the SPOOL and Migration volumes.(2) At the
                          end of the month, the maximum GB of disk for the
                          month will be computed using this formula:

                          Max GB consumed -
                            max (SPOOL/Migration) + max (pool 1) + max (pool 2)
                          + xxx + (pool n)

                          where the "max" will be the highest value recorded for
                          that pool at any time within the month and "n" will be
                          the last pool being forecasted.

                          For example: if 2 pools are being used in the
                          computation:
                          Pool 1:6/1@ 12:00 = 90 GB
                          ...
                          Pool 1:6/12@ 12:00 = 100 GB
                          Pool 1:6/12@ 18:00 = 110 GB
                          ...
                          Pool 1:6/30@ 18:00 = 95 GB

                          Pool 2:6/1@ 12:00 = 190 GB
                          ...
                          Pool 2:6/15@ 12:00 = 200 GB
                          ...
                          Pool 2:6/1@ 12:00 = 1095GB

                          The maximum for pool 1 =
                          110 GB and the maximum for
                          pool 2 = 200 GB. The Max
                          Disk Consumed metric

Missing Data              In the event that data is missing or corrupted for any
                          given time, Unisys will average the data from the
                          previous good time period with the following good time
                          period.  For example, if a 4 hour collection period is
                          used and if 4 hours of data are missing, Unisys would
                          average the previous 4 hour sample with the next 4
                          hour sample to compute an average for the missing
                          period.

                          Unisys would clearly report exactly what method and
                          samples it used in computing metrics for any lost
                          period.

(1) - Interval Accounting: The actual time a job executes within prime shift
      and off-prime shift will be accounted for separately. For example,
      assuming prime shift is 8AM to 5PM, and a job runs from 7 AM to 9AM
      (regardless of when it was submitted), it will accumulate 1 hour of
      off-prime shift time and 1 hour of prime shift time.

Conversion Factor

Since it is expected that new processor speeds/models will be used, a
conversation must be done to convert application CPU hours on all machines to a
common metric. The conversation factor is the multiplier that will be applied to
convert that machine to ES9021-340 CPU hours (the base metric).

BILLING REPORTING

From the SMF data, Unisys will sum all CPU hours for all appropriate account
codes (see prior list). The hours in these Account Codes will be converted to a
common metric and summed monthly to provide the total CPU hours consumed. Unisys
will provide two monthly metrics; one metric for total prime shift CPU hours and
one metric for off-prime shift CPU hours. Unisys will also provide an EXCEL
spreadsheet that contains the detail used to create this report.

                                       TO
                   INFORMATION TECHNOLOGY SERVICES AGREEMENT

This is Amendment Number 2, dated as of June 30, 1999, to the Information
Technology Services Agreement dated as of June l, 1996 between UNISYS
CORPORATION ("Unisys") and UNITED HEALTHCARE SERVICES, INC, ("UHS"), as amended
September 15, 1997 (the Agreement").

The Agreement sets forth the parties' obligations relating to (i) ownership of
certain Unisys Machines and System Software, (ii) Termination Charges and (iii)
pricing adjustments in the event of the occurrence of certain base volume
changes. Unisys has requested such provisions be amended in certain respects and
UHS has agreed to amend such provisions in accordance with this Amendment Number
2. Terms not otherwise defined herein shall have the meaning given them in the
Agreement.

ACCORDINGLY, in consideration of the premises and other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged,
Unisys and UHS hereby agree to amend the Agreement to incorporate the following
additional provisions and modify certain clauses as follows:

1.       Notwithstanding anything to the contrary contained in the Agreement or
         any exhibits thereto, upon the termination, in whole or in part only
         with respect to the A-Series and Clearpath Unisys Machines, of the
         Agreement for any reason prior to its expiration, UHS shall, upon
         request of Unisys, only with respect to (i) any A Series and Clearpath
         Unisys Machines and related peripherals described on Exhibit A attached
         hereto and (ii) Unisys proprietary System Software described on Exhibit
         A attached hereto, be obligated to (i) purchase such A-Series and
         Clearpath Unisys Machines and related peripherals and (ii) license such
         Unisys proprietary Systems Software for the remaining term of the
         Agreement, solely for an amount equal to the amount set forth on
         Exhibit B attached hereto. Upon the sale of any Unisys Machines and
         related peripherals to UHS under this Amendment Number 2, Unisys will
         represent and warrant that it has the full right, title and interest in
         such Unisys Machines and related peripherals free and clear of any
         liens, claims or encumbrances and that such Unisys Machines and related
         peripherals are in good working order and eligible for Unisys
         maintenance services in accordance with Unisys then existing
         maintenance agreements. It is understood and agreed by the parties
         that, in the event UHS terminates the Agreement in full or only with
         respect to one or more of the A-Series and Clearpath Unisys Machines,
         and Unisys requests that UHS purchase the A-Series and Clearpath Unisys
         Machines and related peripherals described on Exhibit A attached hereto
         and license the Unisys proprietary System Software described on Exhibit
         A attached hereto, UHS will only be obligated to pay (i) those fees
         then due and payable under the Agreement at the time of termination and
         (ii) the amount set forth on Exhibit B attached hereto. Notwithstanding
         the foregoing, in the event

<PAGE>
         that UHS terminates the Agreement pursuant to Section 24.05 of the
         Agreement, UHS shall not be obligated to pay the applicable amount set
         for on Exhibit B attached hereto for such A-Series and Clearpath Unisys
         Machines and related peripherals if UHS has not received the full right
         title and interest in such Unisys Machines and related peripherals free
         and clear of any liens, claims or encumbrances. No other fees or
         charges of any kind shall apply. For clarification purposes only,
         termination solely with respect to one or more IBM or Unix machines
         shall be in accordance with the terms and conditions of the Agreement
         (specifically including Amendment 1).

2.       Upon mutual agreement of the parties, which agreement will be in the
         sole discretion of the parties, Exhibit A attached hereto will be
         amended, from time to time, as the A-Series and Clearpath Unisys
         Machines and Unisys proprietary System Software subject to this
         Amendment Number 2 are substituted by Unisys. Exhibit B attached hereto
         will not be amended or modified as a result of any such amendment of
         Exhibit A attached hereto. The intent of the parties is that Exhibit A
         attached hereto reflects all of the hardware and Unisys proprietary
         System Software required to process the UHS workload as of the date of
         this Amendment Number 2. Unisys hereby represents that Exhibit A
         attached hereto includes a complete and accurate list of all the
         A-Series and Clearpath Unisys Machines and Unisys proprietary System
         Software required to process the Unisys related UHS workload as of the
         date of this Amendment.

3.       Section 33.01(1) of the Agreement is hereby amended by adding the
         following sentence to the end of the paragraph:

         "Notwithstanding the above, Unisys may assign its right to receive
         payments under this Agreement; provided, however, that any such
         assignment (a) will not increase the number of payments  or amounts due
         from UHS, (b) will be subject to any claims and offset rights as well
         as UHS's right to receive payment for unused credits of UHS and (c)
         will not affect any of UHS's rights or remedies under the Agreement."

4.       The first paragraph under the title "BASE CHANGES - VOLUME AND RATE" on
         page 1 of Exhibit 31-3 of Amendment Number 1 to the Agreement is hereby
         amended by adding the following sentence to the end of such paragraph:

         "It is understood and agreed and it is the intent of the parties hereto
         that, with respect to A-Series and Clearpath Unisys Machines only, in
         the event that an adjustment to the base rate is made as a result of a
         reduction in the actual unit volume consumed for a specific category,
         the parties will negotiate in good faith an appropriate adjustment to
         the base rate to reflect the capacity reductions and volume changes.
         Adjustments to the base rate pursuant to this paragraph will not in any
         way affect, reduce, amend or alter the parties rights or obligations
         under Article 9 of the Agreement."

5.       The first sentence of the paragraph titled "ALL PERIODS" on page 1 of
         Exhibit 31-3 of Amendment Number 1 to the Agreement is hereby amended
         to read in its entirety as follows:

         "If the base volume for a particular category falls below either 60% of
         the base volume existing as of the date of this Amendment Number 2 for
         the Unisys category, or 60% of the initial base volume for the IBM
         categories, the Account Executives for Unisys and UHS will jointly
         agree on a revised rate card for that category. The Account Executives
         will also agree on a one-time charge for the reduced capacity
         requirement, or if UHS re-assigns the volume of one product family
         (IBM, Unisys) to the other product families supported by Unisys, the
         Account Executives for Unisys and UHS will jointly agree on an
         appropriate one-time charge for the eliminated capacity requirement."

6.       Section 30.01 of the Agreement is hereby amended to read in its
         entirety as follows:

                  30.01(a) Direct Damages. Each of UHS and Unisys shall be
         liable to the other Party for any direct damages arising out of or
         relating to a breach of its obligations under this Agreement. The
         following shall be considered direct damages and Unisys shall not
         assert that they are indirect, incidental, special, or consequential
         damages or lost profits to the extent they result from Unisys failure
         to provide the Services in accordance with this Agreement:

                  (1)      reasonable costs of recreating (if possible) or
                           reloading any of UHS' or its Affiliates' information
                           that is lost or damaged;

                  and (ii) the charges paid to Unisys by UHS during the twelve

                  immediately prior to the date the amount of damages was
                  established. Notwithstanding the preceding two sentences, in

                  UHS an amount equal to the charges paid to Unisys by UHS
                  during the four (4) month period immediately prior to the date

                  Section 29.01(1), Section 29.01(7), Section 29.02(1) and
                  Section 29.02(7), (c) any breach of confidentiality
                  obligations contained in this Agreement or the improper
                  disclosure of UHS Data, or (d) liability resulting from the
                  willful misconduct of a Party.

7.       It is the intent of the parties that Exhibit 17 of the Agreement is
         superseded in its entirety by Amendment Number 1 and this Amendment
         Number 2.

8.       Other Terms

                ADDITION TO ARTICLE 33 MISCELLANEOUS PROVISIONS

33.18 External Access. This section establishes the terms and conditions and
procedures of Unisys access to certain of UHS' Systems noted on the Security
Form ("United IS").

(1). Method of Access. Unisys shall have access to United IS by the following
methods:

-        At a UHS Site using UHS owned or leased equipment.

-        As otherwise mutually agreed to by the Parties.

(2). System Users. As part of the Agreement, UNISYS shall identify to UHS the
UNISYS employees UNISYS believes will need to have access to United IS under the
Agreement ("SYSTEM USERS"). UHS will provide each System User with a hard copy
of the UHS customer administration request form that is used by UHS to process
adds, changes and deletes regarding access to the United IS, which is located in
the UHS Lotus Notes database (the "SECURITY FORM"). The UHS designated contact
will forward the completed Security Form to the UHS security group for
processing. UNISYS shall provide UHS the information regarding each System User
reasonably required by UHS, including, but not limited to, the United IS each
System User will access and the method of each System User's access to United
IS. UNISYS will not provide social security numbers or other UNISYS or personal
confidential information to UHS.

UNISYS shall promptly notify UHS of any System Users who cease to require access
to United IS as a result of a change of responsibilities and/or leaving UNISYS
employment. UHS may terminate any System User's access to United IS in the event
UHS has good faith reason to believe such access is not authorized, or access
must be terminated in order to prevent damage to UHS. UNISYS is responsible for
a System User's non-compliance with the terms of this Agreement. UNISYS
subcontractors shall be deemed System Users under the terms of the Agreement.

         In the event UHS terminates an UNISYS System User's access to the
United IS for any reason other than (1) a material breach of the Agreement or
(2) a force majeure event, and such access is necessary for UNISYS to perform
the Services, the Parties will mutually agree to either (1) develop an
alternative means to access the data on the United IS that is necessary for
UNISYS to perform the Services or (2) delay the delivery of any deliverables
under the Agreement, with no contractual penalty being assessed against UNISYS.

                                        6

<PAGE>

(3). Limitations on UNISYS Use of Access to United IS. UNISYS shall not use its
access to United IS for any purposes not authorized by an Agreement.

(4). No Software License Granted and Ownership. The access to United IS granted
to UNISYS under the Agreement is limited to granting UNISYS access to the United
IS and does not and shall not be construed as granting UNISYS a license for the
use of the software programs contained in the United IS. Any license to the
software programs contained in United IS shall be pursuant to a separate license
agreement between the Parties. UNISYS shall not and shall not attempt to reverse
engineer or otherwise obtain copies of the software programs contained in United
IS or the source code of the software programs contained in United IS.

UHS represents and warrants to UNISYS that it either owns and/or has rights to
the United IS and it owns or has rights to allow UNISYS to access and use the
software and applications on the United IS solely for the purposes set forth in
the Agreement. This section to the Agreement does not transfer title to or
ownership to rights to United IS or to rights in patents, copyrights, trademarks
and trade secrets encompassed in the United IS to UNISYS.

(5). Security. UNISYS shall use reasonable physical and software-based measures,
commonly used in the electronic data interchange field as such are provided by
UHS to UNISYS or that UNISYS uses in its normal course of business, to protect
data contained in United IS from unauthorized access. UNISYS shall comply with
and shall not attempt to circumvent or bypass UHS's security procedures for the
United IS that are required by UHS and provided to UNISYS during the performance
of the SOW. UNISYS shall advise UHS if conformance with such requirements will
result in additional burdens on UNISYS, and if such burdens will affect UNISYS
ability to deliver the Services and/or increase UNISYS costs to perform the
Services. Notwithstanding the foregoing, any such Changes to the Agreement will
be processed by the Parties in accordance with the terms and conditions of the
Agreement.

ADDITIONAL NEW PARAGRAPH IN SECTION 22.01 CONFIDENTIAL INFORMATION

         "While it is not contemplated under this Agreement that Unisys will
have a need to use or disclose Protected Health Information or Personal
Information (as those terms are defined below), in connection with providing
services to UHS, in the event Unisys does, this section shall apply.  In
addition to its obligations of confidentiality under this Agreement, Unisys
understands and acknowledges that it may receive from or create or receive on
behalf of UHS Protected Health Information, as defined under the privacy
regulations issued pursuant to the Health Insurance Portability and
Accountability Act of 1996 ("HIPAA"), and/or nonpublic personal information, as
defined under the Gramm-Leach-Bliley Act and implementing regulations ("GLB"),
during the performance of its obligations under this Agreement. Unisys agrees
to comply with any information privacy and security policies and standards of
UHS that are disclosed by UHS to Unisys in writing and that are applicable to
the aforementioned information. Except as otherwise specified herein, Unisys
may use or disclosure Protected Health Information received from or created or
received on behalf of UHS ("PHI") and nonpublic personal information received
from or created or received on behalf of UHS ("Personal Information") solely to
perform functions, activities, or services for, or on behalf of, UHS as
specified in this Agreement. With regard to its use and/or disclosure of PHI or
Personal Information, Unisys hereby agrees and represents and warrants to UHS
that Unisys shall:

(a)      Not use or further disclose any PHI or Personal Information other than
as permitted by this Agreement.
(b)      At all times maintain and use appropriate safeguards to prevent uses
or disclosures of any PHI or Personal Information other than as permitted by
this Agreement;
(c)      Ensure that any subcontractor or agent to whom it provides any PHI or
Personal Information agrees in writing to the same conditions and restrictions
that apply to Unisys with regard to the PHI or Personal Information, including,
without limitation, all of the requirements of this Section 22.

With regard to its use and/or disclosure of PHI, Unisys hereby agrees and
represents and warrants to UHS that Unisys shall:
(a)      Report promptly to UHS any use or disclosure of any PHI of which it
becomes aware that is not permitted by this Agreement;
(b)      Mitigate, to the extent practicable, any harmful effect that is known
to Unisys of a use or disclosure of PHI by Unisys in violation of the
requirements of this Agreement;
(c)      In the time and manner designated by UHS, make available PHI in a
Designated Record Set, to UHS, or as directed by UHS, to an individual, in
order for UHS to respond to individuals' request for access to information
about them in accordance with the HIPAA privacy regulation;

                                       9
<PAGE>
(d)      In the time and manner designated by UHS, make any amendments or
corrections to the PHI in a Designated Record Set that UHS directs in
accordance with the HIPAA privacy regulation;
(e)      In the time and manner designated by UHS, document such disclosures of
PHI and information related to such disclosures as would be required for UHS to
respond to a request by an individual for an accounting of disclosures of PHI in
accordance with the HIPAA privacy regulations;
(f)      In the time and manner designated by UHS, make available to UHS, or as
directed by UHS, to an individual, the information documented in accordance
with subsection (e) above, to permit UHS to respond to a request by an
individual for an accounting of disclosures, in accordance with the HIPAA
privacy regulations;
(g)      In the time and manner designated by UHS or the Secretary of HHS, make
its internal practices, books and records relating to the use and disclosure of
PHI available to UHS and to the Secretary of HHS for purposes of determining
UHS's compliance with the HIPAA privacy regulations.

         Unisys agrees that this Agreement may be terminated by UHS upon written
notice to Unisys in the event that UHS determines that Unisys has violated any
material term of this section. Alternatively, UHS may choose to provide Unisys
with written notice of the existence of an alleged material breach of this
section and afford Unisys an opportunity to cure said breach upon mutually
agreeable terms. Failure to cure, or a determination by UHS that cure is not
practicable or possible, shall be grounds for the immediate termination of this
Agreement. Unisys agrees to defend, indemnify and hold harmless UHS against any
and all claims, liabilities, judgments or damages asserted against, imposed upon
or incurred by UHS that arise out of any violation of this section.

         Upon the termination of this Agreement for any reason, Unisys shall
return to UHS or destroy all PHI and/or Personal Information, and retain no
copies in any form whatsoever. This provision shall apply to PHI and/or Personal
Information that is in the possession of subcontractors, vendors or agents of
Unisys. Unless otherwise specified in this Agreement, all capitalized terms in
this section not otherwise defined have the meaning established for purposes of
Title 45 parts 160 and 164 of the UHS States Code of Federal Regulations, as
amended from time to time. The Parties agree to take such action as is necessary
to amend this Agreement from time to time as is necessary for UHS to comply with
the requirements of HIPAA, the HIPAA privacy regulations, GLB and other federal
and state privacy and consumer rights laws and regulations applicable to UHS.
Unisys agrees to cooperate with and assist UHS in order for UHS to meet its
obligations under applicable privacy laws and regulations. This section shall
survive any termination of this Agreement. The terms and conditions of this
section required by HIPAA shall be construed in light of any applicable
interpretation of and/or guidance on the HIPAA privacy regulation issued by HHS

                                       10
<PAGE>
         from time to time. Any ambiguity in this section shall be resolved in
         favor of a meaning that permits UHS to comply with applicable laws and
         regulations.

Notwithstanding  anything to the contrary  contained in this Section 22.01,  UHS
acknowledges and agrees that Unisys has no independent  knowledge of the
requirements  of HIPAA or GLB or any regulations  promulgated  pursuant
thereto.  As a result,  to the extent that any of the obligations  of Unisys
with regard to PHI or Personal  Information  are determined by, relate or refer
to the provisions of HTAA, GLB or any regulations relating thereto,  Unisys
shall be bound by any such  obligation only if and to the extent that Unisys has
been informed by UHS, in writing,  (via policies and procedures or otherwise) of
the requirements of such provision and the procedures that Unisys must follow in
order to comply with such  obligations.  If and to  the  extent  that,  when  so
informed,  Unisys  determines  that  compliance  with  such obligations would be
commercially  unreasonable or unduly burdensome,  Unisys shall so notify UHS and
the  parties  shall work  together  in good  faith to  develop a mutually
acceptable solution,  including,  without limitation,  restricting Unisys's
access to the applicable PHI or Personal Information, if practicable."

                     PHARMACY BENEFIT MANAGEMENT AGREEMENT

         This Amendment is made to the agreement ("Agreement") between United
HealthCare Services, Inc. and UnitedHealth Networks, Inc., collectively
referred to as "United", and the entity named below ("MMMC"). The Agreement
currently sets forth the terms and conditions under which MMMC or an affiliate
shall provide or arrange for the provision of health care services to
individuals covered by a United's affiliated Health Plan pursuant to its
Medicare contract with the Health Care Financing Administration ("HCFA"). The
parties understand and agree that the Balanced Budget Act of 1997 ("BBA")
established a new program known as Medicare+Choice, which replaced Health
Plan's existing Medicare risk program. The purpose of this Amendment is to
incorporate all provisions necessary to meet the HCFA requirements for
Medicare+Choice. This Amendment is effective on August 1, 1999.

1.       The Agreement shall be amended by the addition of the attached
         Health Plan Medicare+Choice Requirements Addendum.

2.       All other provisions of the Agreement shall remain in full force and
         effect.

                     MEDICARE+CHOICE REQUIREMENTS ADDENDUM

In addition to PBM's obligations under the Agreement, PBM agrees, and shall
require PBM Contracting Providers to agree, as participating providers under a
United affiliated Health Plan's contract with HCFA to be a Medicare+Choice
managed care organization (hereafter the "M divided by C Contract"), to abide by
all applicable provisions of the M+C Contract and to fulfill PBM's and PBM
Contracting Provider's obligations under the Agreement in a manner consistent
with a United affiliated Health Plan's (hereafter the "Health Plan") obligations
under the M divided by C Contract. For purposes of this Addendum, "Medicare
Member" means a Health Plan's Member who is enrolled in a Medicare+Choice plan
through Health Plan. PBM and PBM Contracting Provider compliance with the M+C
Contract specifically includes, but is not limited to, the following
requirements:

1.       Prompt Payment. Health Plan shall pay "clean" claims for Covered
         Services within forty-five (45) days of receipt and approve or deny all
         claims that are not "clean" claims within sixty (60) days from the date
         of the request.

2.       Medicare Compliance. PBM shall, and shall require PBM Contracting
         Providers to, comply with all applicable Medicare laws and regulations
         and HCFA instructions.

3.       Audits and Information. In addition to PBM's and PBM Contracting
         Provider's obligations under Section 5.3.2, PBM shall, and shall
         require PBM Contracting Providers to, permit audits and inspection by
         HCFA and/or its designees, and cooperate, assist and provide
         information to HCFA and/or its designees as requested from time to
         time. This provision shall survive termination of the Agreement.

4.       Maintenance of Records. In addition to PBM's and PBM Contracting
         Providers' obligations under Section 5.3.2, PBM shall, and shall
         require PBM Contracting Providers to, retain books, contracts,
         documents, papers and records, including without limitation, medical
         records, patient care documentation, and other records that pertain to
         any aspect of services performed, financial solvency, reconciliation of
         benefit liabilities and determination of amounts payable under Health
         Plan's M divided by C Contract for a minimum of six (6) years from the
         end of the applicable one-year contract period in the M divided by C
         Contract or the completion of an audit, or in certain instances
         described in applicable Medicare+Choice regulations, for periods in
         excess of six (6) years, if appropriate. PBM shall, and shall require
         PBM Contracting Providers to, maintain such records accurately and
         update them on a regular basis. PBM and PBM's employees and agents
         shall, and shall require PBM Contracting Providers to, maintain the
         confidentiality of all Medicare Member records in accordance with the
         applicable laws and regulations, and shall safeguard Medicare Members'
         privacy. This provision shall survive termination of the Agreement.

5.       Data Collection. PBM shall submit to Health Plan, upon request, all
         data necessary for Health Plan to fulfill its reporting obligations
         pursuant to 42 C.F.R.SS.422.516. PBM must submit to Health Plan all
         data, including medical records, necessary to characterize the content
         and purpose of each encounter with a Medicare Member. PBM must certify
         (based

                                       1
<PAGE>
    on best knowledge, information and belief) the accuracy, completeness and
    truthfulness of such data on certification forms provided by Health Plan.
    PBM shall hold harmless and indemnify Health Plan for any fines or penalties
    it may incur due to PBM's submission of inaccurate or incomplete data.

6.  Accountability.  PBM acknowledges, and shall require PBM Contracting
    Providers to acknowledge, that Health Plan oversees and is responsible to
    HCFA for any functions or responsibilities provided or performed by PBM or
    PBM Contracting Providers pursuant to the M+C Contract, as applicable.

7.  Delegation.  If any service or activity to be performed by PBM under this
    Agreement is delegated, to the extent permitted by and in accordance with
    this Agreement, to a downstream entity, such entity shall enter into a
    contract with PBM obligating such entity to perform such service or activity
    consistent with and in compliance with the terms of this Agreement and the
    M+C Contract.

8.  Continued Care.  In addition to PBM's and PBM Contracting Providers'
    obligations pursuant to Section 3.8 of the Agreement, PBM shall, and shall
    require PBM Contracting Providers to, provide Covered Services to Medicare
    Members (i) for all Medicare Members, for the duration of the M+C Contract
    period for which HCFA payments have been made; and (ii) for Medicare Members
    who are hospitalized on the date the M+C Contract terminates or in the event
    of Health Plan's or PBM's insolvency, through discharge.  This provision
    shall survive termination of the Agreement.

9.  Compliance with Pharmacy Services Manual.  PBM shall require PBM Contracting
    Providers to comply with PMB's Pharmacy Services Manual, including, without
    limitation, the Medicare Plus Choice Requirements addendum (the "Pharmacy
    Attachment").  PBM shall comply with those requirements of the Pharmacy
    Attachment applicable to the performance of PBM's obligations under this
    Agreement, including, without limitation, where an obligation is placed upon
    PBM Contracting Providers but such obligation may be performed or could be
    violated by PBM.  In the event of a conflict between any provision in this
    ADDENDUM and the Pharmacy Attachment, this ADDENDUM shall govern.
