PROPOSAL REVISION



We submitted a proposal on August 31, 1999 to provide IT program management,
applications development and computer operations services to CalPX. This
revision reflects changes to our original proposal based on discussions with
CalPX executives regarding the scope of services ad CalPX baseline IT budgets.
Based on these discussions, we have revised our proposal to better reflect
CalPX's budget plans regarding baseline IT services. Our revised proposal calls
for increasing the scope of our services at CalPX to also cover applications
testing and desktop support and procurement services, It also entails changes in
implementation timeline, baseline staffing and baseline pricing by Perot
Systems.

According to our proposal:

         1.       CalPX and Perot Systems will start negotiation of a Services
                  Contract immediately after the acceptance of the proposal by
                  CalPX.

         2.       We foresee contract negotiations to last about one month
                  during which time Perot Systems will conduct a due diligence
                  study under the existing Task Order 5 between CalPX and Perot
                  Systems. All

- --------------------------------------------------------------------------------

                  funds collected for the due diligence study will be credited
                  against the fees to be paid by CalPX under the Services
                  Contract if it is executed by both parties. Once signed, the
                  Services Contract will supercede Task Order 5.

         3.       We would start the transition of all program management and
                  applications development services to Perot Systems as soon as
                  practical after the Services Contract is signed. This
                  transition, described in the proposal, is expected to last one
                  month.

         4.       At the end of the transition time period IT program management
                  and IT applications development services for CalPX will be
                  provided by Perot Systems.

         5.       We will conduct a study of the computer operations,
                  applications testing and desktop support and procurement
                  services starting in month three and complete this study in
                  month six. In the same time period we will conduct a series of
                  studies as indicated in Appendix B ("Additional Projects") of
                  the proposal. At the end of this study, either party may
                  decide not to proceed with the transfer of computer operations
                  services, applications testing services or desktop support and
                  procurement services to Perot Systems. Failure to reach an
                  agreement by both parties to transfer computer operations
                  services, applications testing services or desktop support and
                  procurement services, will have no bearing on the transfer of
                  program management and applications development services to
                  Perot Systems.

         6.       Should both parties agree to transfer computer operations and
                  applications testing services to Perot Systems, we would
                  transition these services to Perot Systems over a one month
                  time period starting in month six. At the end of the
                  transition period, computer operations and applications
                  testing services for CalPX will be provided by Perot Systems.

         7.       Should both parties agree to transfer desktop support and
                  procurement services to Perot Systems, we would transition
                  these services to Perot Systems over a one month time period
                  starting in January 2000. At the end of the transition period
                  desktop support and procurement services for CalPX will be
                  provided by Perot Systems.

BENEFITS TO CALPX

Our proposed solution will enable CalPX to have predictable IT performance and
costs and to have the flexibility to address CalPX business requirements in
California and beyond. In addition, we believe that our solution will allow
CalPX to meet its budgeted goals for IT services.

The following table presents the baseline cost of our solution along with
CalPX's IT budget numbers for the proposed IT services.

and timeline
- ----------------------------------------------------------------------------------------------


We believe that there may be substantial additional savings that can be realized
if we are selected to perform these services. These savings include:

         -        Savings due to possible restructuring of CalPX's MCI and IBM:
                  contracts;

         -        Savings due to a potential earlier transfer of desktop support
                  and procurement services to Perot Systems;

         -        Savings due: to potentially moving the entire CalPX IT staff
                  to Pasadena;

         -        Savings due to potential elimination of backup disaster
                  recovery site at Folsom; and

         -        Savings due to consolidation of all IT services and
                  elimination of "phantom IT organisms" throughout CalPX,
