                                    Article 2
                        Account Management and Personnel

2.1  Account Manager. Perot Systems shall designate an Account Manager ("Account
     Manager") who shall be directly responsible for coordinating, managing and
     supervising the delivery of the Services and shall have full authority to
     act on Perot Systems' behalf with respect to all matters relating to this
     Agreement. The Account Manager shall work with the CalPX Representative to
     address CalPX's information technology issues and strategies and the
     parties' relationship under this Agreement. The initial Account Manager
     shall be Dariush Shirmohammadi.

2.2  Change of Account Manager.

     a.   Unless CalPX agrees, Perot Systems shall not replace or reassign the
          Account Manager for a period of not less than 12 months after the date
          of his or her assignment to the CalPX account unless such Account
          Manager (a) voluntarily resigns his or her employment or terminates
          his or her contract of engagement with Perot Systems, (b) is dismissed
          by Perot Systems for misconduct, (c) fails to perform his or her
          duties and responsibilities pursuant to this Agreement, (d) dies or





          is unable to work due to his or her disability, or (e) independently

          (a) notify the CalPX Representative of the proposed assignment, (b)
          introduce the individual to appropriate representatives of CalPX, and
          (c) provide the CalPX Representative with the qualifications and any
          other appropriate information regarding the individual that may be
          requested by the CalPX Representative. In the event the CalPX
          Representative does not approve of an individual which Perot Systems
          proposes to appoint as an Account Manager, Perot Systems shall in good
          faith select an alternate candidate and shall follow the procedure set
          forth in this subsection with respect to such candidate.

2.3  Perot Systems Key Employees. With respect to the persons identified in
     Schedule 2.4 (the "Key Personnel"), the parties agree as follows:

     a.   The individuals serving as Key Personnel shall each be dedicated to
          the CalPX account on a full-time basis.

          Schedule 2.4 as Key Personnel, as a replacement for any Key Personnel,
          Perot Systems shall (a) notify the CalPX Representative of the
          proposed assignment, (b) introduce the individual to the CalPX
          Representative and, (c) provide the CalPX Representative with the
          qualifications and any other appropriate information regarding the
          individual that may be requested by the CalPX Representative. If the
          CalPX Representative does not approve of the assignment of such
          individual as Key Personnel, Perot Systems shall in good faith select
          an alternate candidate and shall follow the procedure set forth in
          this subsection with respect to such candidate.

     c.   Unless CalPX agrees otherwise, Perot Systems shall not replace or
          reassign any individual assigned to the CalPX account as Key Personnel
          during a period of 12 months from the date of his or her assignment as
          Key Personnel unless such individual (a) voluntarily resigns from, or
          terminates his or her contract of engagement with, Perot Systems, (b)
          is dismissed by Perot Systems, (c) fails or is not qualified to
          perform his or her duties and responsibilities pursuant to this
          Agreement, (d) dies or is unable to work due to his or her disability,
          (e) independently initiates a request for reassignment for personal
          reasons, or (f) the services of such Key Personnel, in Perot Systems'
          reasonable opinion and with the concurrence of the CalPX

          Agreement.

     d.   If, in CalPX's opinion, any individual assigned to the CalPX account
          as Key Personnel should not remain assigned to the CalPX account, then
          CalPX shall advise Perot Systems of such opinion, and Perot Systems
          shall promptly investigate


                                       2




          the matter and take appropriate action which may include (a) removing
          such individual from his or her status as Key Personnel and notifying
          CalPX of such removal and replacing such individual with another
          qualified individual; or (b) other appropriate disciplinary action.

     e.   Perot Systems shall maintain recruiting and replacement procedures for
          Key Personnel designed to assure an orderly succession in as prompt a
          manner as reasonably possible for any Key Personnel who resign or are
          replaced.

2.4  PSC Personnel. Perot Systems shall assign qualified personnel as PSC
     Personnel to perform the Services under this Agreement. On a quarterly
     basis, Perot Systems shall provide to the CalPX Representative a list of

          requests and standard rules and regulations of CalPX regarding safety,
          health and personal conduct generally applicable to CalPX and vendor
          personnel working at such CalPX premises, including (i) subject to
          each individual person serving as PSC Personnel being provided with a
          copy, complying with the CalPX Employee Code of Conduct, (ii) wearing
          an identification badge, and (iii) otherwise conducting themselves in
          a businesslike manner.

     b.   Perot Systems shall cause the PSC Personnel to comply with (a) the
          confidentiality provisions of this Agreement, and (b) CalPX's computer
          security procedures, a current copy of which is attached as Schedule
          2.5, as amended by CalPX from time to time.

     c.   If CalPX reasonably determines that any PSC Personnel are not
          conducting themselves in accordance with this Section, CalPX shall
          notify Perot Systems of the non-compliant conduct. Upon receiving such
          notice, Perot Systems shall promptly investigate the matter and take
          appropriate disciplinary action which may include (a) removing the
          applicable person from the CalPX account, providing CalPX with notice
          of such removal, and replacing him or her with another qualified
          person, or (b) other disciplinary action reasonably anticipated to
          prevent a recurrence. If there are repeated violations of this Section
          by a particular individual, Perot Systems shall remove the individual
          from the CalPX account. Perot Systems shall notify the CalPX
          Representative immediately after dismissing or reassigning any PSC
          Personnel whose normal work location is at a CalPX service location.
          Except as otherwise approved by CalPX, those PSC Personnel located on
          CalPX's premises may only provide services on such premises which
          support CalPX's operations.


                                       3

     relating to this Agreement. The CalPX Representative shall work with the
     Account Manager to address CalPX's information technology issues and

                3.1;

          (iii) the Applications Maintenance Services described in Part C of
                Schedule 3.1; and

          (iv)  the IT Procurement Services.

     (b)  Applications Development Services are described in Part D of Schedule

3.2  Service Levels.

     (a)  In the absence of adequate historical data from the operation of
          CalPX's Systems, the parties agree to use the service levels set forth
          in Schedule 3.2 ("Service Levels") for the Services. These Service
          Levels have been selected based upon industry data and a partial
          analysis of the operation of CalPX's Systems and the number of PSC
          Personnel assigned to perform the Services. During the first 120 days
          after the Effective Date ("Transition Period"), Perot Systems and
          CalPX shall diligently and in good faith negotiate any changes to the
          Service Levels that are required to reflect the actual operation of
          CalPX's Systems during the six-month period prior to the Effective
          Date. After the Transition Period, Perot Systems shall meet or exceed
          the mutually agreed Service Levels with respect to the Services. The
          addition of any Service Level not set forth on Schedule 3.3 as of the
          Effective Date shall require an amendment to this Agreement.

     (b)  Perot Systems shall be excused from its obligation to perform the
          Computer Operations Services in accordance with the Service Levels to
          the extent that it can not meet such Service Levels as a result of
          actions or failures to act by CalPX in acceptance with this Agreement
          or by a third party other than Perot Systems or PSC Personnel,
          including any failure to obtain any access described in Section 4.2(b)
          or Force Majeure Event.

     (c)  As contemplated by the Change Control Procedure, (i) any Change Order
          implementing service or resource additions or reductions requested by
          CalPX and any other Change Order changing the manner in which the Core
          Services are provided by Perot Systems shall include an appropriate
          adjustment to the applicable Service Levels, and (ii) Perot Systems
          shall review with CalPX as part of the Change Order Procedure the
          anticipated effect of such reduction, addition or change on Perot
          Systems' ability to meet the applicable Service Levels.

     (d)  If Perot Systems fails to meet any Service Level, Perot Systems shall
          (i) promptly investigate and perform a root-cause analysis to identify
          the cause of the failure; (ii) provide to CalPX a report on the causes
          of the problem; (iii) correct the problem, to the extent such problem
          is within its control, or take appropriate steps to cause the problem
          to be corrected to the extent such problem is not within its control;
          (iv) to the extent within its control, take appropriate preventive
          measures to reduce the probability of a recurrence of the problem; (v)
          take appropriate actions to mitigate the adverse effects of the
          problem prior to its correction; and (vi) periodically advise the
          CalPX Representative of the status of remedial efforts being
          undertaken with respect to such problems.


                                       6




3.3  Additional Services.

     (a)  Perot Systems shall provide to CalPX such additional services that are
          beyond the scope of the Base Services ("Additional Services") as Perot
          Systems and CalPX from time to time agree in writing. Base Services,
          Additional Services, and any Transition Assistance provided under
          Section 7.11 are collectively referred to herein as "Services." Upon
          identifying a need for information technology or business consulting
          services outside the scope of the Base Services, the Account Manager
          and the CalPX Representative shall coordinate the preparation of a
          document identifying, in reasonable detail, the services to be
          performed, the specific hardware, software and third party services to
          be delivered as part of such services, and the objective completion
          criteria to be applied in connection with such services. This document
          shall be reviewed by the IT Steering Committee.

     (b)  Perot Systems acknowledges and agrees that CalPX prefers to use
          commercial off-the-shelf software, rather than custom-designed
          solutions, to meet its requirements whenever and wherever practical,
          and Perot Systems shall use reasonable commercial efforts to identify
          commercial off-the-shelf software products that are suitable for use
          by CalPX as part of any proposal to provide Additional Services.

     (c)  If CalPX, in its sole and absolute discretion, chooses to terminate
          the contract of any third party vendor that is providing desktop,
          network or telecommunications information technology services, or such
          contract expires in accordance with its terms, and CalPX (i) desires
          to obtain such services from another third party and (ii) determines
          in its reasonable discretion that Perot Systems has the appropriate
          expertise and resources to provide such services, then CalPX and Perot
          Systems shall commence good faith negotiations for Perot Systems to
          provide such services. In the event that following such good faith
          negotiations, the parties shall not have reached agreement on the
          terms of Perot Systems providing such services within 30 days of the
          commencement of such negotiations, then CalPX shall have the right to
          enter into an agreement with a third party to provide such services;
          provided that prior to entering into a definitive agreement for the
          provision of such services Perot Systems shall be offered the
          opportunity to resubmit another proposal for the provision of such
          services. CalPX acknowledges and agrees that Perot Systems has, as of
          the Effective Date, the technical capability and experience to perform
          the Desktop Support Services and Desktop Procurement Services.

     (d)  Additional Services will be performed under individual written task
          order ("Task Orders") that are approved and issued in accordance with
          this Section 3.3 and the Change Control Procedure. Each Task Order
          shall identify, in reasonable detail, the services to be performed,
          the specific hardware, software and third party services to be
          delivered as part of such services, and the objective completion
          criteria to be applied in connection with such services, in addition
          to the price, reimbursable expenses and pass-through expenses to be
          paid by CalPX for such Additional


                                       7




          Services. Perot Systems will commence the Additional Services upon
          execution of the Task Order by CalPX and Perot Systems.

3.4  Change Control Procedure.

     (a)  All Changes (as defined herein) shall be reviewed by the Change Review
          Board. All Change Orders shall be reviewed and approved in writing by
          the Account Manager and CalPX Representative. The budgetary and
          schedule effects of reasonably interrelated Change Orders shall be
          aggregated to determine whether the CalPX Representative or the Change
          Review Board should review such Change Orders. The parties shall use
          their reasonable commercial efforts to minimize any adjustments to
          development schedules, development budget and application
          requirements. Change Orders may be approved electronically by the
          Account Manager and the CalPX Representative.

     (b)  During the first 30 days after the Effective Date, Perot Systems shall
          prepare and deliver to the Change Review Board, for its review and
          approval, the Change Control Procedures to be used under this
          Agreement to control Changes in scope, schedule and cost "the
          Services. The Change Control Procedures shall provide, at a minimum,
          that. (i) all Changes, including Changes to the Change Control
          Procedures, shall be made pursuant to the Change Control Procedures,
          except as may be necessary on an emergency basis; (ii) no Change which
          is reasonably expected to materially or adversely affect the function
          or performance of any System or result in a material increase in the
          charges to CalPX under this Agreement shall be implemented without the
          Change Review Board's approval, except as may be necessary on an
          emergency basis; (iii) all Changes, except those made as necessary on
          an emergency basis, shall be implemented in accordance with a schedule
          provided to the Change Review Board periodically and under
          circumstances that are reasonably expected not to interrupt CalPX's
          business operations materially; and (iv) the Account Manager shall
          give the Change Review Board prompt notice (which may be given orally,
          provided that any oral notice is confirmed in writing within five
          business days) of any Change made as necessary on an emergency basis.

     (c)  Changes to the application requirements, development budget, or
          development schedule shall be made only by mutual agreement of the
          affected parties through the use of a Change Order. All requests for
          Changes by a party shall be communicated by the Account Manager or
          CalPX Representative, as the case may be, to the CalPX Representative
          or Account Manager, as the case may be, or the Change Review Board as
          appropriate. No party shall have any obligation or authority to
          implement Changes requested through any other means.

     (d)  Requests for Change Orders shall be submitted for review in accordance
          with the Change Control Procedure, and shall include the following
          information: (i) a


                                       8




          detailed description of the Change requested, (ii) the business,
          technical or financial justification for the Change requested, (iii)
          the price, capital and operating costs associated with the Change
          requested, (iv) the projected schedule impact of the Change requested,
          and (v) the priority of the Change requested.

     (e)  Within ten business days (or such longer period as is mutually
          agreeable) after receiving a request from CalPX for a Change Order,
          Perot Systems shall prepare and provide to CalPX's Representative or
          the Change Review Board a document summarizing the effect, if any, of
          the proposed Change on (i) the development schedule, including but not
          limited to CalPX's obligations under the development schedule, (ii)
          the functionality and requirements of the applicable System to be
          delivered, and (iii) the development budget. In addition, Perot
          Systems shall inform CalPX regarding any other business impact that
          Perot Systems believes to be relevant to an evaluation of the Change
          Order. The CalPX Representative or the Change Review Board, as the
          case may be, shall review the information and, as the Change Review
          Board deems necessary, revise it at the next succeeding Change Review
          Board meeting and promptly forward its report on the proposed Change
          to CalPX. Within ten business days or such longer period as is
          mutually agreeable to the parties, after receiving such information,
          CalPX will approve, reject or withdraw the request for such Change
          Order. CalPX's failure to approve, reject or withdraw the request
          within the applicable time period shall be deemed a withdrawal of such
          request.

     (f)  Upon submitting a request for a Change Order initiated by Perot
          Systems, Perot Systems shall provide to CalPX a document summarizing
          the effect, if any, on (i) the development schedule, including but not
          limited to CalPX's obligations under the development schedule, (ii)
          the functionality and requirements of the applicable System to be
          delivered, and (iii) the development budget. In addition, Perot
          Systems shall inform CalPX regarding any other business impact that it
          believes to be relevant to an evaluation of the Change Order. The
          Change Review Board shall review the information and, as the Change
          Review Board deems necessary, revise it at the next succeeding Change
          Review Board meeting and promptly forward its report to CalPX. Within
          ten business days after receiving such information (or within ten
          business days after receiving the Change Review Board's report, in the
          case of a Change request reviewed by the Change Review Board), CalPX
          shall approve or reject the requested Change Order. CalPX's failure to
          approve or reject the requested Change Order within the applicable
          time period shall be deemed a rejection of such request.

     (g)  In any case where no final agreement has been reached on a Change
          request but the CalPX Representative nonetheless orders Perot Systems
          to carry out such Change, Perot Systems shall use its commercially
          reasonable efforts to carry out such Change within the time requested
          by CalPX at the price and related terms proposed


                                       9




          by Perot Systems, and either party may refer the disputed Change
          request to the procedures provided in Section 7.2 and 7.3.

3.5  IT Procurement Services. At CalPX's written request, Perot Systems shall
     purchase, lease or license equipment, software, services and supplies from
     Perot Systems' suppliers on behalf of CalPX and for CalPX's account or
     shall facilitate the purchase, lease or license of such items by CalPX at
     the prices available to Perot Systems (the "IT Procurement Services").

3.6  Management Procedures Manual. On or before the end of the Transition Period
     and as part of the Services, (1) CalPX and Perot Systems shall establish
     procedures pursuant to which mutually agreed policies of CalPX and Perot
     Systems shall be adhered to during the Term, and (2) Perot Systems shall
     prepare and deliver to CalPX, for CalPX's approval, a management procedures
     manual (the "Management Procedures Manual") generally describing (a) the
     Services, (b) the computer hardware and software environments in which the
     Services will be performed, (c) the documentation, if any, which provides
     further details regarding the Services or computer hardware and software
     environment in which the Services will be performed, (d) the procedures
     Perot Systems intends to use to manage the Services, and (e) the management
     reporting system that Perot Systems shall use to manage this Agreement and
     communicate to CalPX. Perot Systems and CalPX shall write the Management
     Procedures Manual whenever necessary to reflect any changes in the
     operations or procedures described therein within a reasonable time after
     such changes are made.

3.7  Reports. Perot Systems shall provide to CalPX performance, utilization and
     status reports relating to the Services and Service Levels as requested by
     CalPX in a form acceptable to CalPX.

3.8  Improved Technology. As part of the Services, Perot Systems shall provide
     CalPX with information about, and recommendations regarding, information
     technology developments that could reasonably be expected to have a
     favorable impact on CalPX's information technology operations for CalPX's
     consideration and evaluation, including information regarding any new
     information technology developments that are not subject to third party
     confidentiality restrictions made generally available by Perot Systems for
     use by Perot Systems' customers. In addition, Perot Systems shall meet with
     CalPX at least twice per year during the Term to inform CalPX of any new
     information technology developments that are not subject to third party
     confidentiality restrictions which Perot Systems is developing and any
     appropriate information processing trends and directions of which Perot
     Systems is aware.

3.9  Changes in Law and Regulations.

     (a)  Perot Systems shall identify and notify CalPX of any changes in any
          laws or regulations applicable to Perot Systems or its operating
          procedures that could adversely affect the use or delivery of the
          Services. CalPX shall identify and notify Perot Systems of any changes
          in any laws or regulations applicable to CalPX or its operating
          procedures that require changes to the way in which the Services are


                                       10




          provided by Perot Systems. Perot Systems and CalPX shall work together
          to identify the impact of any such laws or regulations on how CalPX
          uses, and Perot Systems delivers, the Services. Each party shall be
          responsible for any fines and penalties arising from its failure to
          comply with any laws or regulations applicable to its business
          operations relating to the delivery or use of the Services.

     (b)  If any changes in laws or regulations prevent Perot Systems from
          performing its obligations under this Agreement, Perot Systems shall
          (i) use commercially reasonable efforts to continue to perform the
          Services and (ii) develop and, upon CalPX's approval, implement a
          suitable workaround for its obligations under this Agreement that
          cannot be performed until such time as Perot Systems can perform its
          obligations under this Agreement without such workaround. If the
          applicable change in law or regulatory requirements is applicable to
          Perot Systems, then Perot Systems shall develop and implement such
          workaround at its own expense. If the applicable change in law or
          regulatory requirements is applicable to CalPX and such change results
          in additional costs to Perot Systems to perform its obligations under
          this Agreement, then CalPX shall pay Perot Systems for its incremental
          costs incurred in connection with making the appropriate changes as
          part of the Base Services or as an Additional Service, as the case may
          be.

3.10 Technical Standards. Perot Systems shall comply with CalPX's information
     management technical architecture and product standards in effect on the
     Agreement Date and as amended pursuant to the Change Control Procedure
     during the Term.

3.11 Knowledge Sharing. At least once every year, and on request after at least
     30 days' notice from CalPX, Perot Systems shall meet with representatives
     of CalPX to explain, at an executive level, how (1) the Systems are
     designed and operate, and (2) the Services are provided.

3.12 Customer Satisfaction.

     (a)  Within 90 days after the Effective Date, Perot Systems shall conduct a
          survey to measure end-user satisfaction with the Services at each
          CalPX site. The survey shall contain questions, and shall be
          administered according to procedures, mutually agreed by CalPX and
          Perot Systems within 60 days after the Agreement Date. Perot Systems
          shall promptly share the results of each such survey with CalPX,
          including, without limitation, copies of the user questionnaires
          completed by any CalPX personnel.

     (b)  At least annually during the Term, Perot Systems shall conduct a
          survey to measure end-user satisfaction with the Services and Perot
          Systems' responsiveness to requests for Services at each CalPX site.
          The survey shall contain questions to be agreed upon by CalPX and
          Perot Systems no later than 30 days before the date on which the
          survey is scheduled to begin. Perot Systems shall promptly share the


                                       11




          results of each such survey with CalPX, including, without limitation,
          copies of the user questionnaires completed by any CalPX personnel.
          The content, scope, and method of each such survey shall be consistent
          with the baseline customer survey conducted under Section 3.12(a), and
          the timing of the surveys shall be subject to mutual agreement.

     (c)  During the last six months of the Term, CalPX may initiate at its
          expense a third-party review of the Services being performed by Perot
          Systems. If CalPX initiates such a review, CalPX shall, within five
          business days after sending notice of such election, provide Perot
          Systems with a list of three unbiased third party benchmarkers
          acceptable to CalPX, none of whom shall be competitors to Perot
          Systems. Perot Systems shall select one of such third party
          benchmarkers to be engaged by CalPX. CalPX and Perot Systems shall
          negotiate in good faith to determine jointly the information to be
          provided to the benchmarker (the "Benchmark Information") and the
          scope and cost of the review, and shall (1) review the Benchmark
          Information and (2) schedule a meeting to address any issues either
          party may have with respect to the Benchmark Information. The
          benchmarker shall review the scope and level of Services then being
          provided under this Agreement, the total number of personnel assigned
          to perform those Services, and the charges for the Services and any
          other appropriate information related to this Agreement and compare
          the scope and level of Services, the total number of personnel
          assigned to perform such Services, and the charges for the Services
          against similar services that are performed by other full service
          information technology outsourcing providers who compete with Perot
          Systems in similar markets in a similar period. The benchmarker
          results shall be treated as Confidential Information.

3.13 Regular Improvement. Perot Systems shall, on a regular basis (1) identify
     processes, techniques, equipment and software that could improve the
     Services and Service Levels and (2) recommend for adoption or acquisition
     non-confidential processes, techniques, equipment, software and tools used
     by Perot Systems that could improve or lower the cost of CalPX's technology
     operations. Perot Systems shall, from time to time, include the information
     required by this Section 3.13 in appropriate reports provided to CalPX
     under this Agreement.


                                    Article 4
                             CalPX Responsibilities

4.1  Cooperation. CalPX shall keep Perot Systems informed, as reasonably
     appropriate, about those aspects of CalPX's business that could reasonably
     have a material effect on the demand for, or provision of, the Services.
     CalPX shall cooperate with Perot Systems to ensure that the Change Control
     Procedure and other processes relating to the Services that are dependent
     upon information from CalPX are not unreasonably delayed by CalPX.


                                       12




4.2  Access to Software.

     (a)  CalPX Proprietary Software. CalPX shall provide Perot Systems with
          access to, and the necessary rights to operate, modify, and enhance,
          its proprietary software listed in Part A of Schedule 4.2 and such
          other proprietary software of CalPX as is necessary for Perot Systems
          to perform its obligations under the Agreement ("CalPX Proprietary
          Software"). CalPX shall pay any access or other fees associated with
          obtaining such rights to the CalPX Proprietary Software. CalPX shall
          pay all license, maintenance and other fees associated with the CalPX
          Proprietary Software.

     (b)  CalPX Vendor Software. CalPX shall provide Perot Systems with access
          to, and the necessary rights to operate and, where necessary to
          perform the Services to modify and to enhance, its vendor software
          listed in Part B of Schedule 4.2 and such other vendor software as is
          necessary for Perot Systems to perform its obligations under the
          Agreement ("CalPX Vendor Software") and shall pay any access or other
          fees associated with obtaining such rights to the CalPX Vendor
          Software. CalPX shall pay all license, maintenance and other fees
          associated with the CalPX Vendor Software. Except as contemplated by
          this Section 4.2(b), Pei ;i Systems' access to, and other rights in
          respect of, CalPX Vendor software shall be subject to the terms of the
          applicable software license agreement between CalPX and the applicable
          vendors. If CalPX is unable to obtain the rights described in this
          paragraph (b), (i) Perot Systems shall be relieved of any obligations
          under this Agreement that cannot be performed in the absence of such
          rights without violating a third person's intellectual property or
          other rights, and (ii) CalPX and Perot Systems shall work together in
          good faith to find an alternative way for CalPX to obtain any Services
          that Perot Systems cannot perform in a manner that is reasonably
          satisfactory to both parties.

4.3  Access to CalPX Facilities. CalPX shall provide Perot Systems access to its
     facilities and shall provide to all PSC Personnel performing Services at
     such facilities, without charge, such office furnishings, janitorial
     service, telephone service, utilities (including air conditioning) and
     office-related equipment (including but not limited to personal computers
     and related software, peripherals and supplies and facsimile machines),
     supplies, and duplicating services as Perot Systems may reasonably require
     in connection with the activities contemplated hereunder. Unless otherwise
     agreed, CalPX shall not be obligated to provide such facilities for PSC
     Personnel performing (i) Services at the RIMF (or another Perot Systems
     data center), (ii) Business Consulting Services, or (iii) any Services on a
     part-time basis, except as may be necessary on a short-term, shared basis.
     CalPX shall procure and purchase at its sole cost and expense all the
     necessary hardware and software of CalPX reasonably required by Perot
     Systems to provide the Services. CalPX shall provide such access 24 hours a
     day, seven days a week. Perot Systems shall obey all generally applicable
     rules and procedures at any CalPX facility of which CalPX has notified
     Perot


                                       13




     Systems. CalPX agrees that such CalPX facilities shall comply with all
     applicable laws and regulations. Access and equipment requirements shall be
     handled through the Change Control Procedure. PSC Personnel shall receive
     similar technologies to those currently in use or contemplated at CalPX.

4.4  Access to Technology. CalPX shall provide Perot Systems with access to its
     hardware, equipment, and technology related items and services listed in
     Schedule 4.4 and such other hardware, equipment and technology related
     items and services as otherwise reasonably necessary for Perot Systems to
     perform its obligations under this Agreement (the "CalPX Technology"),
     CalPX shall pay all costs and expenses, including without limitation,
     maintenance costs, associated with the CalPX Technology.

4.5  Required Improvements. CalPX shall implement, or cause to be implemented,
     each of the process, infrastructure, testing and project management
     improvements described in Schedule 4.5, and the initiation of the
     maintenance windows set forth in Schedule 4.5 ("Required Improvements"). If
     CalPX does not implement, or cause to be implemented the Required
     Improvements, the provisions of Section 5.3(b) shall not apply until after
     the Required Improvements have been implemented. The estimates of
     additional expenditures, implementation times and requirements for
     additional Full-Time Equivalent resources set forth in Schedule 4.5 as to
     Required Improvements are subject to change in accordance with the Change
     Control Procedures. CalPX agrees to provide funding for those Required
     Improvements that require additional expenditures or additional external
     resources. Upon the request of CalPX, Perot Systems agrees to provide the
     additional external resources as Application Development and Business
     Consulting Services under this Agreement. Expenditures for hardware,
     software and third party services to implement the Required Improvements
     shall be the responsibility of CalPX.

                                    Articles
                           Payments to Perot Systems

5.1  Base Services Fees.

     (a)  During the Transition Period and thereafter until the Required
          Improvements are completed, Perot Systems shall invoice CalPX on or
          before the 10th day of each month the Calculated Services Fee for each
          of me Core Services, the Application Development Services and the
          Business Consulting Services provided during the previous month. After
          the Transition Period and the Required Improvements have been
          completed, Perot Systems shall invoice CalPX on or before the 10th day
          of each month for (i) an amount equal to the Baseline Budget per month
          for the Core Services to be provided during the following month, plus
          (ii) the Calculated Services Fee for each of the Application
          Development Services and the Business Consulting Services provided
          during the previous month.

     (b)  After the Transition Period and the Required Improvements have been
          completed, the invoice for the first month of each calendar quarter
          shall reflect any credit due to CalPX, and any additional amount
          payable by CalPX, for all adjustments to the previously invoiced
          amounts mat are required under this Agreement, including but not
          limited to any adjustments required pursuant to Section 5.3 (the
          "Quarterly True- Up"). Perot Systems shall not modify any previously
          prepared Quarterly True-Up, subject to the provisions of Section 5.8.

5.2  Additional Services Charges. During the Term, CalPX shall pay Perot Systems
     each month for the Additional Services the amounts agreed to by CalPX and
     Perot Systems at the times agreed to by Perot Systems and CalPX. Additional
     Services shall be provided on a time and materials basis using Perot
     Systems' "Standard Commercial Rates", less a 25% discount. Perot Systems
     may adjust the Standard Commercial Rates no more often than once per year,
     beginning in the second year of the Term, with 60 days advance written
     notice.

5.3  Performance Bonuses and Credits.

     (a)  CalPX and Perot Systems have established the "Baseline Budget" set
          forth in Schedule 5.1, which represents CalPX's good faith projection
          of the fixed and variable costs and expenses that would have been
          incurred or paid by CalPX to perform the Core Services on a monthly
          basis in the absence of this Agreement, minus a level of savings
          projected in good faith to be achievable as a result of the Required
          Improvements and other improvements initiated by Perot Systems. The
          Baseline Budget shall be adjusted annually as provided in Section 5.6.

     (b)  If during any calendar quarter in which the Calculated Service Fees
          for the Core Services (calculated in accordance with paragraph A of
          Schedule 5.1) are less than the Baseline Budget for the Core Services,
          as adjusted in accordance with Section


                                       15




          5.6, for that calendar quarter, then Perot Systems shall credit CalPX
          an amount equal to one-half of the amount by which the applicable
          Baseline Budget exceeds such Calculated Service Fees. The credit shall
          be issued on the first invoice issued to CalPX following the
          completion of that calendar quarter; provided that no such credit
          shall be issued until after the Transition Period and the Required
          Improvements have been completed.

     (c)  If during any calendar quarter the Calculated Service Fees for the
          Core Services (calculated in accordance with paragraph A of Schedule
          5.1) are greater than the Baseline Budget for the Core Services, as
          adjusted in accordance with Section 5.6, for that calendar quarter,
          then CalPX shall pay Perot Systems an amount equal to one-half of the
          amount by which the applicable Calculated Service Fees exceed the
          applicable Baseline Budget, which amount shall be included on the
          first invoice issued to CalPX following the completion of that
          calendar quarter.

5.4  Reimbursable Expenses. CalPX shall pay or reimburse Perot Systems for its
     reasonable out-of-pocket travel and travel related expenses incurred in
     connection with its performance of the Services that arise in connection
     with any travel by the PSC Personnel outside of the greater Los Angeles
     area requested by CalPX. Notwithstanding the preceding sentence, CalPX
     shall not pay or reimburse Perot Systems for travel or travel-related costs
     incurred by PSC Personnel assigned to perform the Base Services for travel
     within the Los Angeles area. Unless otherwise agreed, any expenses shall be
     reimbursed according to CalPX Expense and Reimbursement Policy, attached as
     Schedule 5.4, as amended from time to time.

5.5  Taxes. There shall be added to any charges payable by CalPX under this
     Agreement, and CalPX shall pay or reimburse to Perot Systems, amounts equal
     to any taxes, however designated or levied based upon such charges, the
     Services, or this Agreement, including state and local taxes, and any taxes
     or amounts in lieu thereof paid or payable by Perot Systems in respect of
     the foregoing, excluding franchise taxes and taxes based on the net income
     of Perot Systems. Each party shall cooperate with the other in minimizing
     any applicable tax and, in connection therewith, CalPX shall provide Perot
     Systems any resale certificates, information regarding out-of-state use of
     materials, services or sales, or other exemption certificates or
     information reasonably requested by Perot Systems.

5.6  Cost of Living Adjustment. If the Price Index at the end of each one year
     period following the Effective Date ("Current Index") is higher than the
     Price Index at the beginning of such one year period ("Base Index"), then,
     effective as of the end of such one year period, all charges hereunder
     shall be increased by the percentage that the Current Index increased from
     the applicable Base Index. "Price Index" means the index entitled "Private
     Industry, Wages and Salaries, 12-Month Percent Change, Not Seasonally
     Adjusted," published by the Bureau of Labor Statistics. If the publisher of
     this index should stop publishing or substantially change the content or
     format of the index, the parties shall substitute therefor another
     comparable measure published by a mutually acceptable source; provided,
     however, that if such change is merely to redefine the base year for the
     Price Index to


                                       16




     another year, the parties shall continue to use the Price Index but shall,
     if necessary, adjust the Base Index and Current Index as reasonably
     appropriate.

5.7  Time of Payment. All amounts due hereunder shall be due within 30 days
     after receipt by CalPX of an invoice therefor. An invoice shall be deemed
     to be received in accordance with the terms of Section 12.2, provided that
     all invoices shall be addressed to the attention of the CalPX Chief
     Financial Officer. CalPX shall deliver a CalPX check to the Account Manager
     at CalPX's offices in Pasadena on the due date and Perot Systems shall not
     charge CalPX for overnight courier. Amounts not paid when due shall incur
     interest until paid at the lesser of (i) 1.5% per month, or (ii) the
     maximum rate permitted by applicable law. If any amount not paid when due
     under this Agreement is disputed in good faith, interest shall not begin to
     accrue until the dispute has been resolved.

5.8  Audit of Charges. Within 30 days after me Effective Date, Perot Systems and
     CalPX shall agree as to the documentation that Perot Systems will provide
     to CalPX each month in support of its charges under this Agreement,
     including reimbursable expenses. Upon notice from CalPX, Perot Systems
     shall provide CalPX and its representatives (collectively, the "CalPX
     Auditors") with access to such financial records and supporting
     documentation as may reasonably be requested by the CalPX Auditors, and the
     CalPX Auditors may audit reasonable appropriate books and records of Perot
     Systems for the purpose of verifying that any amounts charged under this
     Agreement with respect to the Services are accurate and in accordance with
     this Agreement. If, as a result of such audit, CalPX determines that Perot
     Systems has overcharged or undercharged CalPX, CalPX shall notify Perot
     Systems of the amount of such overcharge or undercharge and Perot Systems
     or CalPX, as the case may be, shall promptly pay the amount due. In
     addition, if any such audit reveals an overcharge to CalPX of five percent
     or more of the aggregate amount of the invoices audited, Perot Systems
     shall reimburse CalPX for the cost of such audit.

5.9  Pass-Through Expenses. Perot Systems shall review all IT vendor invoices
     for Pass-Through Expenses, including but not limited to invoices relating
     to IT Procurement Services, to determine whether the charges reflected in
     such invoices comply in all material respects with the applicable purchase
     documentation or contract. After completing its review, Perot Systems shall
     submit an invoice to CalPX for such IT vendor invoices, together with Perot
     Systems' recommendation for payment, nonpayment, or partial payment, to
     CalPX twice per month on or about the fifth and twentieth days of the month
     for CalPX's review and payment. CalPX shall promptly review and pay the
     invoices submitted to it (or advise Perot Systems' Account Manager that an
     invoice is not approved, with an explanation of the reasons for not
     approving the invoice).

5.10 Adjustment of Budget.

     (a)  During any 12-month period commencing as of the Effective Date, CalPX
          may, in one or more installments, reduce the Baseline Budget (as
          adjusted in accordance with Section 5.6) as of the beginning of such
          12-month period by a percentage


                                       17




          amount up to a percentage equal to the sum of (i) 5% (the "Reduction
          Percentage"), plus (ii) the aggregate number of percentage points, if
          any, for all of the unused portions of the Reduction Percentages with
          respect to all previous 12- month periods, provided that CalPX may not
          exercise such right to reduce the Baseline Budget until after the
          Transition Period and Required Improvements are completed. If during
          any three calendar month period commencing after the Transition Period
          and the Required Improvements are completed the average number of
          transactions settled through CalPX's settlement system during such
          three-month period is less than 50% of the average number of
          transactions settled through CalPX's settlement system during the
          Transition Period, CalPX and Perot Systems shall negotiate appropriate
          adjustments to the Baseline Budget, the number of Full-Time Equivalent
          PSC Personnel providing Core Services, the Service Levels, and
          Schedule 7.8 provided that the reduction in the number of transactions
          settled is the result of circumstances outside CalPX's reasonable
          control.

     (b)  If CalPX elects to reduce the Baseline Budget as provided in Section
          5.10(a), CalPX shall give Perot Systems at least (i) 90 days prior
          written notice of any budget reduction of 5% or less of the applicable
          Baseline Budget, (ii) 135 days prior written notice of any budget
          reduction of 5% to 10% of the applicable Baseline Budget, and (iii)
          180 days nor written notice of any budget reduction of more than
          10% of the applicable Baseline Budget. On the effective date of any
          reduction in the Baseline Budget, Perot Systems shall have the right
          to reduce the number of Full-Time Equivalent PSC Personnel performing
          Core Services under this Agreement, and Perot Systems and CalPX shall
          adjust the Service Levels and Schedule 7.8 as appropriate to reflect
          the staffing adjustments.

5.11 No Other Charges. There shall be no other charges payable by CalPX other
     than those stated in this Article 5, Schedule 5.1 and Schedule 5.2.

5-12 Fee Disputes.

     (a)  Within 30 days after receiving each invoice, CalPX shall give notice
          to Perot Systems of any amount shown in such invoice that is
          reasonably disputed in good faith by CalPX, which notice shall include
          a reasonably detailed explanation of the disputed amount and the
          grounds for the dispute. CalPX's failure to pay amounts disputed in
          accordance with this Section 5.12 shall not be grounds for a claim of
          breach or suspension of work by Perot Systems so long as CalPX
          complies with the provisions of Section 5,12(b). CalPX shall pay any
          amounts to Perot Systems within five business days after such amounts
          are found to be payable to Perot Systems. If the aggregate disputed
          invoiced amounts exceed $120,000, then CalPX shall pay all such
          disputed amounts, on or before 30 days after giving notice of dispute,
          into escrow in a major United States commercial bank with which
          neither party has significant dealings, with interest to be allocated
          to the party entitled to


                                       18




          the principal upon resolution of the dispute, which dispute shall be
          resolved through good faith negotiation or otherwise in accordance
          with Article 7.

5.13 Proration. All periodic fees under this Agreement are to be computed on a
     calendar month basis and shall be prorated for any partial month.

5.14 Unused Credits. Any unused credits against future payments owed to either
     party by the other pursuant to this Agreement shall be paid to the
     applicable party within 30 days after the expiration or termination of this
     Agreement.

5.15 Retention of Records. Perot Systems shall retain records and supporting
     documentation sufficient to document the Services and the fees paid or
     payable by CalPX under this Agreement for a period of seven years after the
     expiration or termination of this Agreement.

6.1  CalPX Data.

     (a)  All data and information (i) provided by or on behalf of CalPX to
          Perot Systems in connection with the Services, (ii) obtained,
          developed or produced by Perot Systems as part of the Services, or
          (iii) to which Perot Systems has access as a result of providing the
          Services ("CalPX Data") shall remain the property of CalPX or the
          third party that owns such data and information. Perot Systems shall
          use such CalPX Data solely in connection with the activities
          contemplated by this Agreement. The CalPX Data shall be treated as
          Confidential Information of CalPX under the Agreement Perot Systems
          hereby irrevocably assigns, transfers and conveys, and shall cause all
          PSC Personnel to assign, transfer and convey, to CalPX without further
          consideration all of its and their right, title and interest in and to
          the CalPX Data.

     (b)  At Perot Systems' expense, Perot Systems shall promptly correct any
          errors or inaccuracies in the CalPX Date and the reports delivered to
          CalPX under this Agreement, to the extent caused by Perot Systems. At
          CalPX's request and expense, Perot Systems shall promptly correct any
          other errors or inaccuracies in the CalPX Data or such reports.

     (c)  Upon request by CalPX at any time during the Term and upon expiration
          or termination of the Agreement, Perot Systems shall (1) promptly
          return to CalPX, in the format and on the media requested by CalPX,
          all or any part of the CalPX Data and (2) erase or destroy all or any
          part of the CalPX Data in Perot System's possession, in each case to
          the extent so requested by CalPX, except for (i) archive and backup
          copies that are not readily accessible for use, and (ii) business
          records required by law to be


                                       19

            retained by Perot Systems. Any archival and backup tapes containing
            CalPX Data shall be deemed Confidential Information of CalPX and
            subject to the provisions of Article 6 and shall be used by Perot
            Systems only for back-up and audit purposes.

6.2    Confidential Information.

       (a)  Confidential Information. Each receiving party shall use at least
            the same degree of care, but no less than a reasonable degree of
            care, to avoid unauthorized disclosure or use of each disclosing
            party's Confidential Information, including any third party
            Confidential Information disclosed by the disclosing party, as it
            employs with respect to its own Confidential Information of similar
            importance. Each receiving party may disclose Confidential
            Information only to the other party to this Agreement and its own
            officers, directors, and employees and to its consultants,
            subcontractors and advisors who reasonably need to know it. Each
            receiving party shall be responsible to the disclosing party for any
            violation of this Agreement by its officers, directors, employees,
            consultants, subcontractors or advisors. No receiving party may
            print or copy, in whole or in part, any documents or other media
            containing a disclosing party's Confidential Information, other than
            copies for its officers, directors, employees, consultants or
            advisors who are working on the matter, without the prior consent of
            the disclosing party. No receiving party may use a disclosing
            party's Confidential Information for competing with the disclosing
            party or for any purpose not in furtherance of this Agreement. The
            term "Confidential Information" is defined to mean, with respect to
            CalPX and Perot Systems, all information, documents, records and
            data, in whatever form or medium (including, without limitation, (i)
            verbal statements summarized in writing within 10 business days,
            (ii) printed and electronic forms, (iii) handwritten notes or
            summaries, (iv) portions of any such items) regarding each other
            party's (a "disclosing party") methodologies, financial affairs,
            business activities and plans and records identified as confidential
            in CalPX's tariff, operating manual and Records Availability Policy
            communicated by a disclosing party to a receiving party.

       (b)  Certain Permitted Disclosures. Each of Perot Systems and CalPX
            shall, however, be permitted to disclose relevant aspects of the
            other party's Confidential Information to its respective officers,
            agents, subcontractors and employees to the extent that such
            disclosure is reasonably necessary for the performance of its duties
            and obligations under this Agreement; provided, however, that such
            party shall take reasonable measures to prevent, and shall remain
            responsible for, the disclosure of Confidential Information of the
            other party in contravention of the provisions of this Agreement by
            such officers, agents, subcontractors (except as otherwise
            specifically provided in this Agreement) and employees.

       (c)  Disclosures Required by Law. If a receiving party is requested, as
            part of an administrative or judicial proceeding, to disclose any of
            a disclosing party's

                                                  20



            Confidential Information, the receiving party shall, to the extent
            permitted by applicable law, promptly notify the disclosing party of
            such request and cooperate with the disclosing party in seeking a
            protective order or similar confidential treatment for such
            Confidential Information. The seeking of protective orders shall be
            at the expense of the party whose Confidential Information is at
            issue.

       (d)  Exclusions. Confidential Information shall not include information
            that (1) was known by the receiving party without an obligation of
            confidentiality prior to its receipt from the disclosing party, (2)
            is independently developed by the receiving party without reliance
            on Confidential Information, (3) is or becomes publicly available
            without a breach of this Agreement by the receiving party, (4) is
            disclosed to the receiving party by a third person who is not
            required to maintain its confidentiality, or (5) is required to be
            disclosed by reason of legal, accounting or regulatory requirements
            beyond the reasonable control of the receiving party.

       (e)  Obligations upon Termination or Expiration. Promptly after the
            expiration or termination of this Agreement, except as provided in
            Section 6.5 with respect to the Developed Software, each receiving
            party shall return or, with the consent of the disclosing party,
            destroy all "the disclosing party's Confidential Information,
            including any third party Confidential Information in the hands of
            either party, except for (i) archive and backup copies that are not
            readily accessible for use, and (ii) business records required by
            law to be retained by the receiving party.

                                       21




       (f)  Certain Privileged Information. Perot Systems acknowledges that
            CalPX may assert that certain documents, data and databases created
            by Perot Systems as part of the Operations Services provided under
            this Agreement and all communications related thereto (collectively,
            "Privileged Work Product") are subject to certain privileges under
            applicable law, including the attorney-client privilege, and may
            seek to protect such Privileged Work Product from disclosure by Rule
            26 of the Federal Rules of Civil Procedure or other applicable rules
            or laws. CalPX shall notify Perot Systems of any Privileged Work
            Product to which Perot Systems has or may have access. After Perot
            Systems receives such notice, Perot Systems shall use reasonable
            commercial efforts to limit access to such Privileged Work Product
            solely to those PSC Personnel for whom such access is required to
            fulfill Perot Systems' obligations under this Agreement. If Perot
            Systems is requested to provide any third party with access to
            Privileged Work Product, Perot Systems shall, to the extent
            permitted by applicable law, promptly notify CalPX and take, at
            CalPX's expense, such reasonable actions as may be requested by
            CalPX to resist providing such access. Perot Systems shall have the
            right, at CalPX's expense, to retain independent legal counsel in
            connection with any such request. If Perot Systems is ultimately
            required, pursuant to an order of a court or other authority
            reasonably believed by Perot Systems to be of competent
            jurisdiction, to disclose Privileged Work Product, Perot Systems
            shall have no liability under this Agreement in connection with such
            disclosure.

       (g)  Internal Audits. Perot Systems may periodically perform, or cause to
            be performed, internal compliance reviews of its activities under
            this Agreement. The specific findings of these reviews other than
            those performed under this Agreement, whether performed by Perot
            Systems or a third person, shall be deemed Privileged Work Product
            and Perot Systems shall not be required to disclose such findings to
            CalPX under any circumstances.

6.3    CalPX Proprietary Software. CalPX Proprietary Software shall be and
       remain the property of CalPX, and Perot Systems shall have no rights or
       interests therein except as required to perform the Services or as
       otherwise provided in this Agreement.

6.4    Perot Systems Software and Perot Systems Tools.

       (a)  Any software that is proprietary to Perot Systems that Perot Systems
            uses or to which Perot Systems provides CalPX access ("Perot Systems
            Software") and any tools or methodologies which are proprietary to
            Perot Systems and used in connection with the activities
            contemplated by this Agreement ("Perot Systems Tools"), including
            any modifications to any Perot Systems Software or Perot Systems
            Tools, shall be and remain the property of Perot Systems, and CalPX
            shall have no rights or interests therein, except as otherwise
            provided in this Agreement.

                                       22



       (b)  Perot Systems shall provide CalPX, Affiliates of CalPX and CalPX
            Partners with access to the Perot Systems Software, Perot Systems
            Tools and Perot Systems' Third Party Software and Third Party Tools
            used in connection with the Services during the Term to the extent
            such access is necessary for CalPX or its Affiliates to receive the
            Services. Upon request, CalPX shall have the right to approve the
            Perot Systems Software, Perot Systems Tools and Third Party Software
            and Third Party Tools prior to their use by Perot Systems in
            connection with the Services.

       (c)  Upon termination or expiration of this Agreement, at the request of
            CalPX, Perot Systems shall grant to CalPX, Affiliates of CalPX and
            CalPX Partners, and the first successor provider of the Services, a
            license to access, use, operate, modify and enhance for CalPX or its
            Affiliate's business operations any Perot Systems Software or Perot
            Systems Tools then being used to provide the Services at Perot
            Systems' then prevailing commercial rates and terms, provided that
            Perot Systems shall not be obligated to grant any license rights
            with respect to any such software and tools to Electronic Data
            Systems Corporation, Computer Sciences Corporation, Andersen
            Consulting LLP or any of their Affiliates for any period in excess
            of 180 days.

       (d)  At the request of CalPX, Perot Systems will commercially
            reasonable efforts to obtain for CalPX, Affiliates of CalPX and
            CdIPX Partners, and the first successor provider of the Services,
            after the expiration or termination of the Agreement license rights
            from the applicable third parties to access, use, operate, modify
            and enhance any Third Party Software and Third Party Tools being
            used by Perot Systems to provide the Services as of expiration or
            termination of this Agreement.

6.5    Rights in Developed Software.

       (a)  Except as otherwise agreed in this Article 6, CalPX shall acquire
            all right, title and interest in and to all Work Product produced
            under this Agreement, including but not limited to all trade
            secrets, copyrights, patents and other intellectual property rights
            in and to such Work Product. Except as otherwise agreed in this
            Article 6, Perot Systems hereby irrevocably assigns, transfers and
            conveys, and shall cause all PSC Personnel to assign, transfer and
            convey, to CalPX without further consideration all of its and their
            right, title and interest in and to such Work Product. Perot Systems
            acknowledges, and shall cause all PSC Personnel to acknowledge, that
            CalPX and the successors and permitted assigns of CalPX shall have
            the right to obtain and hold in their own name the intellectual
            property rights referred to above in and to such Work Product
            including all rights of patent, copyright, trade secret or other
            proprietary rights. Perot Systems agrees to execute, and shall cause
            all PSC Personnel to execute, any documents or take any other
            actions as may reasonably be necessary, or as CalPX may reasonably
            request, to perfect or register CalPX's ownership of any such Work
            Product.

                                       23



       (b)  All Perot Developed Software and related Documentation shall be
            owned by Perot Systems. To the extent that any of the Perot
            Developed Software and related Documentation is deemed a "work for
            hire" by operation of law, except as otherwise provided in this
            Article 6, CalPX hereby assigns, transfers and conveys, and shall
            cause CalPX Affiliates and agents to assign, transfer and convey, to
            Perot Systems without further consideration all of its and their
            right, title and interest in and to such Perot Developed Software
            and related Documentation including all rights of patent, copyright,
            trade secret or other proprietary rights. CalPX acknowledges that
            Perot Systems and the successors and permitted assigns of Perot
            Systems shall have the right to obtain and hold in their own names
            such intellectual property rights in and to the Perot Developed
            Software and related Documentation. CalPX agrees to execute any
            documents or take any other actions as may be necessary, or as Perot
            Systems may reasonably request, to perfect Perot Systems* ownership
            of or register such intellectual property rights in any Perot
            Developed Software and related Documentation.

            (i)   Unless otherwise agreed in this Article 6, Perot Systems shall
                  grant and hereby does grant to CalPX, subject to the terms of
                  this Article 6 and the terms and condition of any license or
                  similar agreement relating to party Embedded Software, a
                  fully paid-up, worldwide, non-exclusive, non-transferable
                  (except as provided in this Agreement) and perpetual license
                  to use, copy, maintain, and modify the Perot Developed
                  Software, Embedded Software and related Documentation for
                  CalPX's use in connection with its own operations. For
                  purposes of this Section 6.5, CalPX's operations shall include
                  the operations of any Affiliate of CalPX and other third
                  parties (i) to whom CalPX provides services in addition to any
                  sublicense of software; or (ii) in whom CalPX has an ongoing
                  equity interest ("CalPX Partners"). CalPX shall be permitted
                  to sublicense such rights to its Affiliates and CalPX
                  Partners. The license granted in this paragraph shall include
                  a non-transferable (except as provided in the Agreement) and
                  perpetual license to use and practice any and all inventions
                  of Perot Systems embedded in any Perot Developed Software,
                  Embedded Software or related Documentation (including those
                  covered by patents and patent applications at any time).

            (ii)  Perot Systems shall provide CalPX with one or more copies of
                  the source code, source code documentation, and other
                  documentation that is reasonably necessary to enable CalPX to
                  enjoy the benefits of the license granted in this Article 6.

            (iii) Unless otherwise specifically agreed in writing by CalPX,
                  Perot Systems shall not license or otherwise use, copy,
                  maintain or modify, or authorize any third party to use, copy,
                  maintain or modify Work Product that is prepared under this
                  Agreement to provide or market electricity services in any
                  Restricted Territory (defined below), during the period while
                  the Work

                                           24



                  Product is being developed and for a period of one (1) year
                  following the expiration or termination of this Agreement. For
                  purposes of this paragraph, the term "Restricted Territory"
                  means the geographic region covered on the Effective Date by
                  the Western Systems Coordinating Council (WSCC), the Electric
                  Reliability Council of Texas (ERCOT), or the Southwest Power
                  Pool (SPP).

       (c)  The term "Embedded Software" is defined to mean pre-existing
            software that is licensed by CalPX or Perot Systems from a third
            party or owned by Perot Systems that is embedded in or is necessary
            to operate the Developed Software. Perot Systems shall retain its
            rights to any Embedded Software that is owned by Perot Systems, but
            grants to CalPX the license rights referred to in paragraph (b)
            above, provided that if any Embedded Software is owned by a third
            party, then the terms of the applicable license shall define each
            party's rights to such Embedded Software.

6.6    Know-How.

       (a)  CalPX acknowledges that, prior to the Effective Date, Perot Systems
            has acquired, conceived, developed or licensed, and after the
            Effective Date shall continue (both independently and as a result of
            performing services under this Agreement) to acquire, conceive,
            develop or license, certain architectures, concepts, industry
            knowledge, techniques and template works of authorship which embody
            copyrights, inventions, trade secrets and other intellectual
            property (collectively, "Know-How") relating to the types of
            services to be performed for CalPX under this Agreement. CalPX
            desires Perot Systems to apply its Know-How in connection with the
            Services, and acknowledges that performance of the Services shall
            enhance and expand the Know-How. Accordingly, Perot Systems may (1)
            develop or distribute products or perform services similar to the
            Work Product (including the Deliverables and the Documentation), and
            (2) use its Know-How to develop or distribute products or to perform
            services for any other person, provided that (i) no such activity
            violates the other provisions of this Article 6, (ii) the Know-How
            does not contain any Confidential Information of CalPX and (iii) use
            of the Know-How does not misappropriate any trade secret rights or
            infringe upon any other copyright, patent or other proprietary
            rights of CalPX. To the extent necessary to enjoy the rights
            described in this Section 6.6, Perot Systems shall retain, whenever
            intellectual property rights are assigned to CalPX under this
            Agreement, (i) a royalty-free, perpetual, worldwide license to use,
            modify and practice any and all inventions of PSC Personnel embedded
            in any Work Product, Perot Developed Software or related
            Documentation (including those covered by patents and patent
            applications at any time) and (ii) the copyright in any templates
            that form the basis for the Work Product (but not the copyright in
            the Work Product derived from the template).

                                       25



       (b)  Perot Systems acknowledges that, prior to the Effective Date, CalPX
            and its employees have acquired, conceived, developed or licensed,
            and after the Effective Date shall continue to acquire, conceive,
            develop or license, certain Know-How. Perot Systems acknowledges and
            agrees that nothing in this Agreement shall restrict in any manner
            the right of CalPX to use any such Know-How in any manner.

6.7    Audit of CalPX's Business. Perot Systems shall provide reasonable support
       to CalPX in connection with an audit of CalPX's business as Additional
       Services. Perot Systems shall not be obligated by this Agreement to
       disclose to CalPX or any other person or entity any information which is
       not reasonably necessary to conduct an audit of CalPX's business, nor
       shall Perot Systems be obligated to divulge any Confidential Information
       of Perot Systems or any third party, except as may be required under
       applicable law. In no event shall Perot Systems be obligated to disclose
       any Confidential Information to any competitor, or Affiliate of a
       competitor, of Perot Systems. CalPX may utilize third parties to conduct
       such audit subject to such third party or parties entering into a
       confidentially agreement reasonably satisfactory to CalPX and Perot
       Systems.

6.8    Data Security. Perot Systems shall establish and maintain mutually
       agreed safeguards against the destruction, loss, or alteration of the
       CalPX Data in the possession of Perot Systems. Perot Systems shall only
       have access to the CalPX production data on an as-needed basis. In the
       event any PSC Personnel discover or are notified of a material breach or
       potential material breach of security of the CalPX Data, Perot Systems
       shall immediately (1) notify the CalPX Representative of the same and (2)
       if the CalPX Data was in the possession of Perot Systems or PSC
       Personnel, as part of the Services, Perot Systems shall investigate the
       breach or potential breach. In addition, at CalPX's request, Perot
       Systems shall promptly provide CalPX Data security reports to CalPX in a
       form to be agreed upon by CalPX and Perot Systems.

6.9    Safety and Security Procedures. Perot Systems shall maintain and enforce
       mutually agreed physical security standards and procedures at each of the
       service locations and comply with CalPX environmental and physical
       security procedures in effect at the CalPX service locations.

6.10   Security Relative To CalPX Competitors. If Perot Systems intends to
       provide the Services from a service location that is shared with (1) a
       third party or (2) any part of the business of Perot Systems that
       competes with the business of CalPX, then, prior to providing any of the
       Services from such service location, Perot Systems shall develop a
       process, subject to CalPX's prior approval, to restrict access to the
       systems in any shared environment in a manner that prevents persons other
       than PSC Personnel from having access to CalPX's Confidential
       Information.

                                       26



                                   Article 7
                       Performance Review and Termination

7.1    Performance Review. The Account Manager and CalPX Representative shall
       meet as often as reasonably requested by either party to review the
       performance of the parties under this Agreement. Each party shall bear
       its own costs and expenses incurred in connection with such review.

7.2    Dispute Resolution. If any continuing dispute between the parties is not
       resolved after reasonable attempts to resolve such dispute are made by
       either party, then, upon the written request of either party, each party
       shall appoint an officer who does not spend most of his or her time on
       activities relating to this Agreement, to meet with the other party's
       officer for the purpose of resolving the dispute. The officers shall
       negotiate in good faith to resolve the dispute without the necessity of
       any formal proceeding. During the course of such negotiations, all
       reasonable requests made by one party to the other for information shall
       be honored.

7.3    Arbitration. Any dispute that is not resolved through negotiation
       pursuant to Section 7.2 shall be settled through mandatory binding
       arbitration in accordance with the dispute resolution procedures
       described in Schedule 9 of CalPX's Tariff and the CalPX's "Supplemental
       Procedures for California Power Exchange Disputes", as shown in Schedule
       7.3 (the Supplemental Procedures for California Power Exchange Disputes)
       administered by the American Arbitration Association, as amended from
       time to time (which tariff provisions are incorporated into and made part
       of this Agreement as if set forth in full). Such arbitration shall be
       final and binding in accordance with the following:

       (a)  American Arbitration Association Rules. Except as specified below or
            otherwise agreed in writing, the arbitration shall be conducted in
            accordance with the then current Commercial Arbitration Rules of
            the American Arbitration Association.

       (b)  Demands and Counterclaims. Any demand for arbitration or any
            counterclaim shall specify in reasonable detail the facts and legal
            grounds forming the basis for the claimant's request for relief, and
            shall include a statement of the total amount of damages claimed, if
            any, and any other remedy sought by the claimant.

       (c)  Panel and Location. The arbitration shall be conducted by an
            arbitration panel consisting of a single neutral arbitrator selected
            in accordance with those Commercial Arbitration Rules. The
            arbitration proceedings shall take place in Los Angeles, California.

       (d)  Panel Actions. The arbitration panel may render awards of monetary
            damages, direction to take or refrain from taking action, or both.
            However, the arbitration panel may not award monetary damages in
            excess of the damages allowed pursuant

                                       27


       to Article 8 or 9. The arbitration panel may, at its discretion, require
       any party to the arbitration to reimburse any other party to the
       arbitration for all or any part of the expenses of the arbitration paid
       by the other party and the attorneys' fees and other expenses reasonably
       incurred by the other party in connection with the arbitration. Judgement
       upon the award rendered in the arbitration may be entered in any court of
       competent jurisdiction.

7.4    Termination for Cause. If either party (i) breaches any of its material
       obligations under this Agreement (excluding CalPX's obligation to pay
       Perot Systems) or (ii) repeatedly breaches any of its other obligations
       and the effect of any such repeated breaches is material, and the
       breaching party fails to cure any such breach within 30 days (or such
       longer period, not to exceed 60 days, if such breach can not be
       reasonably cured within such 30 day period and the breaching party
       commences to cure such breach upon receipt of notice and diligently
       pursues a cure for such breach) after receipt of written notice from the
       other party identifying such breach, then the nonbreaching party may
       terminate this Agreement by providing the breaching party with prior
       written notice of termination.

7.5    Termination for Non-Payment. If CalPX fails to pay Perot Systems any
       undisputed amounts due hereunder and fails to cure such nonpayment within
       10 days after receipt of written notice from Perot Systems identifying
       such nonpayment, then Perot Systems may terminate this Agreement by
       providing CalPX with prior written notice of termination.

7.6    Termination for Insolvency. ANY LICENSE CONTEMPLATED BY THIS AGREEMENT
       SHALL BE DEEMED AN EXECUTORY CONTRACT UNDER SECTION 365(n) OF TITLE 11 TO
       THE U.S. BANKRUPTCY CODE AND SHALL REMAIN IN FULL FORCE AND EFFECT UPON
       THE LICENSEE'S ELECTION AND THE LICENSEE'S SUBSTANTIAL PERFORMANCE
       HEREUNDER, NOTWITHSTANDING ANY BANKRUPTCY OR INSOLVENCY OF THE LICENSOR.

       If either party is unable to pay its debts generally as they come due or
       is declared insolvent or bankrupt, is the subject of any proceedings
       relating to its liquidation, insolvency or for the appointment of a
       receiver or similar officer for it, makes an assignment for the benefit
       of all or substantially all of its creditors, or enters into an agreement
       for the composition, extension or readjustment of all or substantially
       all of its obligations, then the other party may, by giving prior written
       notice thereof to such party, terminate this Agreement as of a date
       specified in such notice of termination.

7.7    Termination for Convenience.

       (a)    CalPX may terminate this Agreement for convenience effective as of
              any time after the second anniversary of the Effective Date by (i)
              giving Perot Systems notice of the termination at least 180 days
              prior to the termination date specified in the notice, and (ii)
              paying a termination fee in accordance with this Section 7.7 in
              the event the date of termination is a date prior to the end of
              the Initial Term.

                                       28





       (b)    The aggregate termination fee payable by CalPX in the event of a
              termination for convenience pursuant to this Section 7.7 prior to
              the end of the Initial Term shall equal an amount equal to
              $6,575.34 times the number of calendar days remaining between the
              termination date and the end of the Initial Term. Fifty percent of
              such termination fee shall be payable 90 days following delivery
              of such termination notice, and shall be paid in accordance with
              Section 5.7. The remaining 50% shall be due on the termination
              date and shall be paid in accordance with Section 5.7. In the
              event of an extension of this Agreement beyond the Initial Term,
              the parties shall negotiate the availability of a termination for
              convenience right and any related fee, if any.

       (c)    If CalPX exercises its right under this Section 7.7, Perot Systems
              shall, not later than 60 days after the termination date, invoice
              CalPX for the Make-Whole Costs and CalPX shall pay the Make-Whole
              Costs within 30 days after receiving the invoice. For purposes of
              this Section 7.7, "Make-Whole Costs" means all reasonable
              out-of-pocket direct costs and expenses resulting from the early
              termination of this Agreement, such as and by way of example only:
              (i) equipment lease termination penalties, prorated over a period
              of the lesser of the Term or the entire lease term during the
              Term, and (ii) "amortized equipment and software costs (subject
              to CalPX's right to elect to take delivery or transfer of such
              equipment or software at Perot Systems' then book value), less
              (iii) any savings realized by Perot Systems in connection with
              CalPX's exercise of its rights under this Section 7.7. Each party
              will use reasonable commercial efforts, and will cooperate with
              the other party or its designee, to minimize the Make-Whole Costs.

7.8    Termination for Causing Failure of Critical Services. If Perot Systems
       (1) as a result of a breach of its obligations under this Agreement
       causes the failure of any specific Critical Service described in Schedule
       7.8 and (2) does not cure such failure with a permanent solution within
       the number of hours identified in Schedule 7.8 as the applicable cure
       period, after receipt of a notice from CalPX with respect to such
       failure, more than the number of disruptions in a six month time period
       set forth in Schedule 7.8 for that Critical Service, then CalPX may, upon
       notice to Perot Systems, terminate this Agreement, in whole or in part,
       as of the termination date specified in the notice. For the purposes of
       this Section 7.8, such failures caused by Perot Systems shall not be
       counted as a disruption (i) during the Transition Period, (ii) prior to
       the date a disaster recovery solution is completed, (iii) to the extent
       the failure of a Critical Service is caused by the failure to complete
       all Required Improvements, (iv) in connection with any failure caused by
       a server that has not had its scheduled maintenance window made available
       by CalPX during the 30 day period prior to the disruption, (v) if Perot
       Systems' inability to cure the failure is caused by any third party's
       failure or inability to provide software, hardware or services necessary
       for Perot Systems to cure the failure, (vi) in connection with any
       failure of a Critical Service caused by the installation of new hardware
       or software that occurs within 30 days after such installation, or (vii)
       in connection with any failure to provide a Critical Service caused by a
       Force Majeure Event.

                                       29






7.9    Force Majeure Termination Provision. If any Force Majeure Event prevents,
       hinders or delays performance of the Services for seven days, in the case
       of Critical Services, or more than 30 days, in the case of all other
       Services, CalPX may procure such Services from an alternate source. If
       the Force Majeure Event continues to prevent, hinder or delay performance
       of the Services for more than 30 days, in the case of Critical Services,
       or more than 45 days, in the case of all other Services, and CalPX can
       obtain such Services from a third party, then CalPX may terminate this
       Agreement, in whole or in part, as of a date specified by CalPX in a
       termination notice to Perot Systems. If CalPX terminates this Agreement
       pursuant to this Section 7.9, such termination will be CalPX's sole
       remedy, and Perot Systems shall have no liability for damages or
       otherwise to CalPX, in connection with the unavailability of any Services
       as a result of any of the designated Force Majeure Events.

7.10   Continuity of Services. Perot Systems acknowledges that the timely and
       complete performance of its obligations pursuant to this Agreement is
       critical to the business and operations of CalPX. Accordingly, in the
       event of a dispute between CalPX and Perot Systems, Perot Systems shall
       continue to so perform its obligations under this Agreement in good faith
       during the resolution of such dispute unless and until this Agreement is
       terminated in accordance with the provisions hereof so long as CalPX
       continues to comply with the terms of Article 5.

7.11   Transition Obligations.

       (a)    Transition Assistance. During the Transition Assistance Period
              (hereinafter defined), Perot Systems shall provide to CalPX the
              Transition Assistance described below as reasonably requested by
              CalPX ("Transition Assistance"). The term "Transition Assistance
              Period" is defined as (i) if this Agreement expires under Section
              1.3, the six month period after the expiration date or termination

              on the date on which a notice of termination is delivered by
              either party through the termination date or, upon CalPX's written
              request prior to the termination date, through the date six months
              after the termination date. The Transition Assistance to be
              provided to CalPX by Perot Systems shall consist of the following:

              (i)    Continuing to perform any or all of the Services then being
                     performed by Perot Systems.

              (ii)   Working with CalPX to develop a plan for the transition of
                     services from Perot Systems to CalPX or another third party
                     provider.

              (iii)  Providing training for personnel of CalPX in the

              (iv)   With respect to any equipment owned by Perot Systems and
                     used solely to perform the Services, CalPX may purchase any
                     such equipment at Perot Systems' then-current book value on
                     an "as is -- where is" basis. With respect to any equipment
                     leased by Perot Systems and used solely to perform the
                     Services, subject to the terms of any applicable lease,
                     Perot Systems shall assign to CalPX Perot Systems' rights
                     and obligations with respect to any such equipment leased
                     by Perot Systems; provided, however, that the lessor under
                     the lease agrees to release Perot Systems from all
                     liability under me lease as of the date of assignment.

              (v)    With respect to any third party services acquired by Perot
                     Returning Systems and used solely to perform the Services,
                     subject to the terms of any applicable third party services
                     agreement, Perot Systems shall assign to CalPX Perot
                     Systems' rights and obligations with respect to any such
                     third party services used by Perot Systems; provided,
                     however, that such third party service provider under the
                     third party service agreement agrees to release Perot
                     Systems from all liability arising under the third party
                     service agreement after the date of assignment

              (vi)   Returning CalPX Proprietary Software, delivering and

                     Work Product, delivering CalPX Data in a format specified
                     by CalPX and cooperating with CalPX and a successor third
                     party service provider.

              (vii)  CalPX shall have the opportunity to offer employment to
                     Transitioned Employees and any replacements for the
                     Transitioned Employees and any other PSC Personnel who are
                     providing Services to CalPX upon expiration or termination
                     of this Agreement. Perot Systems shall provide CalPX with
                     reasonable access to such PSC Personnel to enable CalPX to
                     meet with, solicit and hire such PSC Personnel. Perot
                     Systems shall waive any non-competition or similar
                     provisions of any agreements or benefit plans that may
                     prevent or inhibit the PSC Personnel from being hired by
                     CalPX, except that Perot Systems shall have no obligation
                     to modify vesting, participation or similar terms in any
                     stock option agreements or stock purchase program
                     agreements.

       (b)    Payment for Transition Assistance. CalPX shall pay Perot Systems
              for such Transition Assistance on a time and materials basis at
              Perot Systems' then-standard commercial billing rates (less a
              discount of 25% in the case of a termination under Sections 7.4,
              7.6, 7.8 or 7.9) or on any other mutually acceptable basis.
              Notwithstanding Section 5.8, CalPX shall pay Perot Systems for any
              Transition Assistance in advance on the first day of each month of
              the Transition Assistance Period an amount equal to Perot Systems'
              reasonable estimate of the total amount

                                       31



              payable to Perot Systems for such Transition Assistance for that
              month adjusted, as necessary, to reflect the reconciliation based
              on the actual charges for Transition Assistance provided during
              the prior month. Perot Systems shall provide CalPX with an invoice
              each month evidencing the estimate of the total amount payable to
              Perot Systems for Transition Assistance for the next month and a
              reconciliation with the actual charges for the Transition
              Assistance provided to CalPX during the prior month.

7.12   Force Majeure. If and to the extent that a party's performance of any of
       its obligations pursuant to this Agreement is prevented, hindered or
       delayed by fire, flood, earthquake, elements of nature or acts of God,
       acts of war, terrorism, riots, civil disorders, rebellions or
       revolutions, or any other similar cause beyond the reasonable control of
       such party (each, a "Force Majeure Event"), and such non-performance,
       hindrance or delay could not have been prevented by reasonable
       precautions, then the non-performing, hindered or delayed party shall be
       excused for such non-performance, hindrance or delay, as applicable, of
       those obligations affected by the Force Majeure Event for as long as such
       Force Majeure Event continues and such party continues to use all
       commercially reasonable efforts to recommence performance whenever and to
       whatever extent possible without delay, including through the use of
       alternate sources, workaround plans or other means. The party whose
       performance is prevented, hindered or delayed by a Force Majeure Event
       shall immediately notify the other party of the occurrence of the Force
       Majeure Event and describe in reasonable detail the nature of the Force
       Majeure Event.

       relating to the settlement thereof, provided that the indemnitee shall
       have the right to approve any settlement or any decision not to defend,
       which approval shall not be unreasonably withheld. The indemnitee's
       failure to promptly give notice shall affect the indemnitor's obligation
       to indemnify the indemnitee only to the extent that the indemnitor's
       rights are materially prejudiced thereby. The indemnitee may participate,

       deem appropriate, at the cost and expense of the indemnitor, which shall
       promptly reimburse the indemnitee for such costs, expenses and settlement
       amounts.

              (i)    Each party shall use reasonable commercial efforts to
                     prevent any software viruses or other surreptitious
                     software codes (collectively, "Virus") from being
                     introduced into the Systems. Perot Systems shall evaluate,
                     recommend and maintain up-to-date, subject to CalPX's
                     approval, virus detection and removal products to be used
                     in connection with the Systems, on a mutually satisfactory
                     periodic basis.

              (ii)   If a Virus is introduced into a System, each party shall
                     use reasonable commercial efforts to identify and
                     neutralize such Virus and to mitigate any adverse effect of

                     soon as, and to the extent, reasonably practicable any
                     data, information or Systems damaged by such Virus. The
                     priority and intensity of the efforts

                     Virus, and to repair or restore any affected data,
                     information or systems, shall be determined by CalPX based
                     on its evaluation of the situation, based on such factors
                     as it deems appropriate, including but not limited to, the
                     number of sites affected, the severity of the damage being
