          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 accordance 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 of 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) me 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) me
          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 shall 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 me 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 update the Management
     Procedures Manual whenever necessary to reflect any changes in me
     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


                                       10




          operating procedures that require changes to the way in which the
          Services are 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


                                       11




          which the survey is scheduled to begin. 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. 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

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


                                       12




     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.

     (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), Perot 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


                                       13




     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 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 the 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 that 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 another year, the


                                       16




     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 the 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 reasonably 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 FT 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 me 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 prior written notice of any budget reduction of more than 10%
          of the applicable Baseline Budget. On the effective date of any
          reduction in me 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 the


                                       18




          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.

          (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

          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,

          copies that are not readily accessible for use, and (ii) business
          records required by law to be retained by Perot Systems. Any archival

          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)

          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 (his Agreement, except as provided in
          Section 6.5 with respect to the Developed Software, each receiving

          destroy all of 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

SCHEDULE 5.4

CalPX Expense Reimbursement Policy

It is the policy of the California Power Exchange Corporation to reimburse its
employees for necessary and reasonable travel and other actual expenses incurred
in the performance of their duties or assignments. Employees are expected to
exercise reasonable and prudent judgement in incurring such expenses. This
policy outlines broadly the types of such expenses, which are acceptable for
reimbursement and the documentation and approval requirements. The department
officers and directors are responsible for managing and approving expense
reimbursements. In addition, they will determine which expenses are reasonable
or unreasonable given the situation and, in conformance with this policy, will
approve all expense reports. Unreasonable expenses will not be reimbursed. The
Chief Financial Officer and Controller may challenge expense requests approved
by officers and directors. The Chief Financial Officer and Controller will have
final approval authority regarding the reimbursement of the expense. It is
expected that employees will submit these expenses for reimbursement on a timely
basis. Reimbursement should be requested when the amount is in excess of $100.00
and not more than 45 days after the expenses are incurred. Expense requests must
be properly documented as to the nature and business purpose of the expenses.

PROCEDURES

DOCUMENTATION

All elements of the expense report must be completed with original invoices or
receipts attached. The only exception to the original invoice requirement is for
airline tickets booked through the Internet (Southwest Airlines only), where a
print out of the download from the Internet will be accepted as an original
invoice. This print out must include the name of the traveler, the dates of
travel, the flight numbers, the departure and destination cities, and the amount
paid. Documentation is required for each expense item in excess of $35.00. For
expenses in excess of $35.00 that are not supported by a receipt, a memo to the
Chief Financial Officer and Controller should be attached explaining why
required procedures were not followed. Reimbursement of these expenses will be
at discretion of the Chief Financial Officer and Controller. Each individual
expense must include the business purpose of the item. An appropriate business
purpose will not be assumed before final approval. The business purpose for the
expenses can be grouped and one explanation provided for all expenses on the
report. The employee must sign the expense report acknowledging the validity of
the charges and supporting the business reason for the request.

APPROVALS




Schedule 5.4 - Page 1




Employees may be required to complete a Travel Authorization form prior to
leaving on a business trip. Use of this document is subject to the discretion of
department senior management. Employees are required to adhere to Travel
Authorization procedures established at the department level. No one is allowed
to approve his or her own expenses and must have their reimbursement request
approved by their supervisor. Expense reports may not be approved by a peer of
the employee's supervisor. The Audit Committee of the Governing Board will
direct the Internal Auditor to review the CEO's expense reports.

TYPES OF EXPENSES
Transportation

      Air Travel

   Employees are expected to use commercial air travel. Use of charter aircraft
   or personal aircraft is not allowed to conduct California Power Exchange
   business. Airfare may be booked through a travel agent the Internet, or
   directly with the Airline. All airfare must be charged to either the company
   American Express or Diners Club card. Employees are responsible for paying
   these charges to the credit card company. Employees should always strive to
   travel at the lowest available fare. If the lowest available fare is not
   utilized, the employee must indicate the reason on the expense report. If
   coach fare is not available, an explanation must be documented on the expense
   report form. Employees may fly business class for scheduled flights more than
   three hours in duration. For scheduled flights less than three hours in
   duration, employees are expected to book coach level fares. The company will
   not reimburse employees for flying first class. Employees are not allowed to
   purchase upgradable coach fares so that first class upgrade certificates can
   be used. In addition, the CalPX will not reimburse employees for the cost of
   first class upgrade certificates. If an employee chooses to upgrade to first
   class travel, only the lowest available coach fare will be reimbursed. Travel
   should not be scheduled to earn frequent flyer awards at the detriment of the
   California Power Exchange. Frequent flyer awards are the property of the
   employees. Expenses will only be reimbursed after travel is completed.
   Receipts showing the total price must be included for reimbursement.

      Car Rental

   Car rental should be limited to use when alternative transportation such as
   taxi or shuttles is not available or not economical. Receipts showing the
   total price must be included for reimbursement. Car rental reservations may
   be made either through a travel agent, the Internet, or directly with the
   rental car company. Compact or intermediate cars should be rented based on
   the




Schedule 5.4-Page 2




   number of employees traveling. Employees should make good judgements as to
   the gasoline options offered with the rental car.

   The California Power Exchange carries liability and vehicle damage insurance
   that protects the CalPX when employees rent vehicles while on CalPX business.
   Employees must indicate on the rental form the California Power Exchange 's
   name to put this insurance into effect. The CalPX will not reimburse
   employees for insurance from rental agencies, or credit cards offers of other
   agencies. Employees should decline insurance coverage offered by rental
   agencies unless they choose to purchase the insurance without reimbursement.
   In the event a California Power Exchange employee has a claim for damage to a
   vehicle while on CalPX business, the employee must contact the Chief
   Financial Officer and Controller immediately so that claims may be processed
   with the CalPX carrier. If an employee rents a vehicle while on California
   Power Exchange business, and extends its time at either the beginning or end
   of the trip for personal reasons, the CalPX insurance only covers the time
   related to CalPX business. Employees are responsible for the cost of vehicle
   insurance while using it for personal use.

      Business use of Personal Vehicles

      When it is necessary for employees to use their personal vehicle for
      business purposes, reimbursement of mileage will be made in lieu of other
      vehicle charges such as gas and oil, insurance, financing costs or other
      wear and tear. The currently approved IRS reimbursement rate will be used.
      No reimbursement will be made for employees' normal commuting to their
      assigned work location. Requests for reimbursement of business mileage
      should reflect a reduction of normal commuting miles.

      Parking. Tolls and Other Costs

      Parking, taxi, shuttle, tolls, tips and other expenses in excess of $35.00
      must be supported by a receipt. Cost of parking fines or other driving
      citations will not be reimbursed.

Lodging

      Aggregations of multiple days stay

      the supporting documentation clearly shows the daily rate and taxes
      applicable. The original receipt from the hotel or motel must be attached.
      Meals, tips, telephone, parking or other charges on the hotel or motel
      bill must be shown in the proper area of the expense report. Movies,
      snacks,

      and mini-bar charges are not reimbursable. Reasonable tips to hotel
      personnel should be shown as other incidental expense.

Meals

      Employee Meals

   Employees' expenses for meals are expected to be reasonable given the
   location. Expenses in excess of $35.00 per meal must have receipts showing
   the name of the establishment and the total amount of the meal including tip.
   Tips should be included in determining the $35.00 amount and be shown as part
   of the meal costs.

      Business Meals

   These expenses must constitute an ordinary and necessary business expense.
   Expenditures should not be lavish or extravagant. Employees must document the
   business purpose of the meal, the name of the restaurant, and include the
   names, titles and the name of the company for all in attendance.

      of the California Power Exchange in connections with the conduct of
      business, documentation as to the nature of the entertainment,
      participants (by name, title and company name), location, and business
      purpose is required.

Non-Reimbursable Expenses

       m general, expenses of a personal nature, that are unreasonable or
       excessive, and that not specifically related to the conduct of the
       business activities of the California Power Exchange are not
       reimbursable. Examples of specifically excluded costs are spousal travel
       expenses, excessive alcoholic beverages, flowers, other gifts for
       employees, credit card fees or interest charges, memberships in travel
       clubs or other airport services. Employee meals, other than for out of
       town travel, are not reimbursable This exclusion includes employee
       working meals which will not be reimbursed. When employees are having a
       meal, the most senior employee, officer or director should report the
       expense so that no one approving expenses for reimbursement would be
       approving a meal in which they participated.

   Civil Procedure Section 1281.9; and,

      (c) any existing or past financial, business, professional or personal
   interests that are likely to affect impartiality or might reasonably create
   an appearance of partiality or bias. Designated mediators or arbitrators
   shall disclose any relationships that they personally have with any party or
   its counsel, or with any individual whom they have been told will be a
   witness. They should also disclose any such relationship involving members of
   their families or their current employers, partners, or business associates.
   Designated mediators or arbitrators shall make a reasonable effort to inform
   themselves of any interests or relationships described above. The obligation

   mediator or an arbitrator from acting in an objective and impartial manner is
   a continuing duty that requires mediators and arbitrators to disclose, at any
   stage of the mediation or the arbitration, any such interests, relationships,
   or circumstances that arise, or are recalled or discovered. If, as a result
   of the continuing disclosure duty, a mediator or an arbitrator makes a
   disclosure which is likely to affect his or her impartiality, or might
   reasonably create an appearance of partiality or bias or if a party
   independently discovers the existence of such circumstances, a party wishing
   to object to the continuing use of a mediator or an arbitrator must provide
   written notice of the objection to the other parties within ten (10) days of
   receipt of the mediator's or arbitrator's disclosure or the date of a party's
   discovery of the circumstances giving rise to that party's objection. Failure
   to provide such notice shall be deemed to be a waiver of such objection. If a
   party timely provides a notice of objection to the continuing use of the
   mediator or the arbitrator, the parties shall attempt to agree whether the
   mediator or the arbitrator should be dismissed and replaced in the manner
   described in Section 5 or 6 of the Procedures. If,




                              Schedule 7.3 - Page 6



   within ten (10) days of a party's objection notice the parties have not
   agreed on how to proceed, the matter shall be referred to the AAA for
   resolution. With respect to intervention proceedings, the term "party" as
   used in this Section 11 shall include only the petitioners) in intervention
   and any challengers.

12.   Modification of Arbitration Procedures

      In determining whether to modify the standard procedures for use in the
   pending matter, the arbitrators) shall consider (a) the complexity of the
   dispute, (b) the extent to which facts are disputed, (c) the extent to which
   the credibility of witnesses is relevant to a resolution, (d) the amount in
   controversy, and (e) the opinions of, and any representations made by, the

       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) unamortized 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 denned), 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 date, as the case may be, or (ii) if
       this Agreement is terminated under Sections 7.4, 7.5,7.6, 7.7, 7.8 or 7.9
       the period beginning 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 performance of the
             Services then being transitioned to CalPX.




                                       30




       (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 the lease as of the date of assignment.

       (v)   With respect to any third party services acquired by Perot 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 installing
             software and tools licensed to CalPX by Perot Systems, delivering
             and installing Developed Software 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




                                       31




       Period an amount equal to Perot Systems' reasonable estimate of the total
       amount 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.

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

                 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 caused, and the
                 relative importance of the Systems affected.

       (b)  Perot Systems shall not, without the prior consent of CalPX,
            intentionally introduce into any System or intentionally invoke any

D - Applications Development Services

a) Application Development Services.

- -  Perot Systems shall assist CalPX personnel to develop, enhance and review the
   functional requirements for Application and Developed Software identified by
   the Program Office that has been approved for acquisition or development
   through the Change Control Procedure in accordance with technology standards,
   development budgets and schedules approved by CalPX from time to time.

- -  Perot Systems and CalPX shall review, and revise as necessary, the functional
   requirements, development budget and development schedule for each
   Application. Following CalPX's approval of these items, Perot Systems shall
   prepare a Change Order confirming the requirements, development budget and
   schedule for submission to the Change Review Board. Work shall begin under
   the Change Order promptly after its execution by CalPX and Perot Systems.

- -  All enhancements to Application shall be considered part of Application
   Development Services.

- -  All services required to introduce or integrate any software into CalPX
   systems, including customization or configuration of such software, shall be
   considered part of Application Development Services, provided, however, that
   if the vendor of Third Party Software requires that (i) such vendor customize
   or configure its software, or (ii) an authorized reseller, systems integrator
   or similar service provider customize or configure its software, then such
   customization or configuration of such software shall not be considered part
   of Application Development Services unless Perot Systems is an authorized
   reseller, systems integrator or similar service provider at the time the
   Third party Software is acquired by CalPX ("Configuration Services").

- -  Perot Systems shall have no obligation to enhance any Application whose
   source code it can not access and modify.

b) Acceptance.

   Acceptance of Deliverables shall be conducted in accordance with the
   following procedures.

- -  Documentation. Perot Systems may submit interim drafts of Documentation to
   CalPX for its review. CalPX shall review each interim draft within 15
   business days after receiving it. When Perot Systems delivers final
   Documentation to CalPX, CalPX shall have the opportunity to review the
   written deliverable for an acceptance period of 10 business days after
   receiving it ("Acceptance Period"), CalPX shall notify Perot Systems' Account
   Manager in writing by the end of the Acceptance Period either stating that
   the Documentation is accepted in the form delivered or describing in
   reasonable detail any deficiencies that must be corrected prior to
   acceptance. If CalPX does not send a deficiency notice by the end of the
   Acceptance Period, the Documentation shall be deemed to be Accepted. If CalPX
   sends a timely notice of deficiencies, Perot Systems shall correct the
   described deficiencies as promptly as possible; provided, however, if Perot
   Systems, upon providing CalPX's Account




                              Schedule 3.1-Page 13




   Manager a detailed justification of its position, does not believe that CalPX
   has identified a deficiency, the parties shall follow the procedures set
   forth in Article 7. Upon receipt of corrected Documentation from Perot
   Systems, CalPX shall have a reasonable additional period of time, not to
   exceed 15 business days, to review the corrected Documentation to confirm
   that the identified deficiencies have been corrected.

- -  Deliverables. At least 30 days prior to the date on which Perot Systems is
   scheduled to deliver any Deliverable to CalPX for testing, Perot Systems
   shall deliver proposed testing procedures for the Deliverable for CalPX's
   review. At least 15 days prior to the date on which Perot Systems is
   scheduled to deliver the Deliverable to CalPX, the parties shall agree upon
   the testing procedures for the Deliverable and the objective criteria for
   determining whether the Deliverable should be accepted ("Acceptance Test
   Plan"). The purpose of the Acceptance Test Plan shall be to determine whether
   the Deliverable performs the functions described in its approved
   specifications and performs the Requirements without any Defects. As used in
   this Agreement, "Defect" means a reproducible failure of a Deliverable to
   satisfy the Acceptance Test Plan. Acceptance of Software deliverables shall
   be conducted in accordance with the following procedures.

        (A)  The Acceptance Test Period for each Deliverable shall be specified
             in the relevant Project Plan.

        (B)  Perot Systems and CalPX shall start to perform Acceptance Testing
             on each Deliverable promptly after receiving Perot Systems' notice
             that the Deliverable is ready for acceptance. Acceptance Testing
             shall be performed as set forth in the Acceptance Test Plan. If
             CalPX determines during the Acceptance Period that the Deliverable
             has one or more Defects, CalPX shall promptly send to Perot
             Systems' Account Manager a notice ("Defect Notice") describing the
             alleged Defect(s) in sufficient detail to allow Perot Systems to
             recreate it or them. The parties shall use commercially reasonable
             efforts to identify all Defects prior to the end of the Acceptance
             Test Period.

        (C)  Perot Systems shall correct any Defects in a Deliverable promptly
             after receiving a Defect Notice and provide the corrections to
             CalPX for re-testing. CalPX shall promptly re-test any corrected
             portions of a Deliverable after receiving the corrections from
             Perot Systems.

        (D)  If any remaining uncorrected Defects exists in the Deliverable at
             the end of the Acceptance Test Period, CalPX shall provide Perot
             Systems by the end of the Acceptance Test Period with notice of me
             final list of outstanding Defects, describing them in sufficient
             detail to allow Perot Systems to recreate them ("Punch List").
             Perot Systems shall correct any Defects identified on the Punch
             List promptly after receiving the Punch List. When all Defects on
             the Punch List have been corrected, Perot Systems shall provide the
             corrections to CalPX. The parties shall have 15 days after receipt
             of the corrections, unless the parties agree to a different period
             in writing, to re-test the corrected Deliverable to confirm the




                              Schedule 3.1-Page 14



             correction of the Defects identified on the Punch List and to
             identify any remaining Defects. If CalPX determines that any
             Defects identified in the Punch List have not been corrected, CalPX
             shall provide Perot Systems by the end of the 15-day re-testing
             period with notice of a revised Punch List, which may include
             Defects not identified on the Punch List. Perot Systems shall
             promptly correct any Defects that are identified in the revised
             Punch List and provide the corrections to CalPX. The parties shall
             have a further 15 day period after receipt of the corrections,
             unless the parties agree to a different period in writing, to re-
             test the corrected Deliverable to confirm the correction of the
             Defects. If CalPX determines as a result of the re-testing that the
             Software deliverable still contains one or more Defects, CalPX
             shall notify Perot Systems' Account Manager, who shall promptly
             cause Perot Systems to perform a root cause analysis of such
             Defects and refer the matter to the IT Steering Committee. If the
             IT Steering Committee is unable to resolve the matter within 15
             days after the matter is submitted to it, any party may submit the
             matter to the dispute resolution procedures set forth in Article 7.

        (E)  Perot Systems and CalPX each agree to work diligently to achieve
             Acceptance of each Deliverable at the earliest possible date.

A.     Service Levels -- General Provisions

During the Transition Period CalPX and Perot Systems shall validate the service
levels set forth in this Schedule 3.3. Commencing with the first full calendar
month after the Transition Period for new Application, each performance metric
shall be measured and reported to CalPX on a monthly basis.

       Perot Systems shall perform Services for which no Service Level is
       specified in this Schedule 3.3 at least at the same level, and with the
       same degree of accuracy, quality, completeness and responsiveness as
       CalPX performed such Services prior to the Effective Date.

       Assumptions and Pre-conditions: Perot Systems' obligation to comply with
       the Service Levels set forth in this Schedule 3.3 is contingent upon the
       accuracy of the assumptions and the satisfaction of the pre-conditions
       set forth below. If any of these assumptions are inaccurate or any of
       these pre-conditions are not satisfied, Perot Systems and CalPX shall
       negotiate in good faith to adjust the Service Levels appropriately or to
       select alternate Service Levels.

       -  Each Service Level shall be measured using then existing measurement
          Tools.

       -  Server availability shall be calculated by dividing (i) the number of
          minutes the applicable server is responding to system commands, by
          (ii) the total number of minutes in the applicable month, based on 7 x
          24 availability, minus the total number of minutes of downtime (a)
          reserved for system maintenance windows, (b) reserved for CalPX
          approved, non-routine maintenance periods, (c) reserved for CalPX
          approved Application installation periods, (d) caused by defects in
          Managed Equipment, Applications (except to the extent such defects
          result from modifications to such Applications made by PSC Personnel),
          or services provided by Third Party Vendors (other than PSC
          Personnel), (e) caused by processing transaction volumes in excess of
          those for which the applicable system was designed, (f) caused by an
          Application that has not been tested in a reasonably adequate test
          environment for a reasonably adequate time period before being placed
          into the production System, and (g) defects in Applications (except to
          the extent such defects result from modifications to such Application
          made by PSC Personnel), or services provided by Third Party Vendors
          (other than PSC Personnel).

       -  CalPX shall authorize the replacement or repair, as reasonably
          appropriate, of any hardware and software reasonably necessary (i) to
          replace hardware that begins to exhibit erratic performance or has
          otherwise become obsolete, (ii) to upgrade such hardware or software
          in accordance with the recommendations




                               Schedule 3.3-Page 1



of its manufacturer, (iii) to interoperate properly with other hardware or
software authorized to be replaced by CaIPX, or (iv) to process the transaction
volumes then being processed by the applicable hardware or software.

Service Levels shall be measured but not enforced until the next calendar month
following each (i) transition to a new hardware or software platform that
affects the applicable Service Level and (ii) implementation of new Applications
that affects the applicable Service Level.

Unless otherwise agreed, the scheduled system maintenance window shall be
12:01 a.m. to 3:00 a.m. Pacific Time each Saturday and Sunday.
