                  (e) independently initiates a request for reassignment for
                  personal reasons, or (f) the services of such Key Personnel,

                  of the CalPX Representative, are no longer required for the
                  performance of this Agreement.

                  is attached as Schedule 2.5, as amended by CalPX from time to
                  time.

         c.       If CalPX reasonably determines that any PSC Personnel are not
                  conducting themselves in accordance with this Section, CalPX
                  shall notify Perot Systems of the non-compliant conduct. Upon
                  receiving such notice, Perot Systems shall promptly
                  investigate the matter and take appropriate disciplinary

                  cooperate with Perot Systems in connection with Perot Systems
                  making such offers. CalPX shall not make any representations
                  to the Transitioned Employees relating to the terms of
                  employment by Perot Systems. If any Transitioned Employee is
                  terminated by Perot Systems within six months after the
                  Effective Date, CalPX shall reimburse Perot Systems for
                  severance costs as same may be incurred by Perot Systems in
                  accordance with Perot Systems' standard employment policies as
                  of the Effective Date. CalPX shall reimburse the severance
                  paid by Perot Systems after presentation of an invoice with
                  supporting documentation in accordance with Section 5.7.

2.8      Subcontractors. Perot Systems may engage independent third parties or
         one or more of its Affiliates to perform as a subcontractor to Perot
         Systems any part of the Services or other obligations to be performed
         by Perot Systems under this Agreement, provided that:

(a)      Perot Systems' Account Manager shall obtain the CalPX Representative's
         prior approval of any subcontractor (other than an Affiliate controlled
         by Perot Systems) that Perot Systems reasonably expects, at the time of
         the initial engagement, shall be

                                        4

             paid more than $250,000 during the term of the agreement under
             which such subcontractor is engaged or, in the case of multiple
             agreements with a single subcontractor, during any 12 month period.
             Such approval shall not be necessary for Affiliates controlled by
             Perot Systems unless otherwise agreed in the Change Control
             Procedure.

      (b)     Perot Systems shall be fully responsible for the work and
              activities of its subcontractors, including the compliance of such
              subcontractors with the terms of this Agreement. Perot Systems
              shall use commercially reasonable efforts to keep CalPX's property
              free from liens arising in connection with the Services performed
              by Perot Systems under this Agreement.

2.9    Regtrictions on Hiring. Except as otherwise specifically provided in this
       Agreement, Perot Systems and CalPX each agree not to hire or recruit the
       other's employees with whom Perot Systems or CalPX came into contact in
       connection with the activities contemplated by this Agreement until the
       earlier of a) six months after the end of the Term; and b) six months
       after such employee is no longer employed by the applicable party,
       without, in each case, the prior written consent of the other party.

                                         Article 3
                                         Services

3.1   Base Senides. During the Term, Perot Systems shall provide the Core
      Services and up to the number of Full-Time Equivalent PSC Personnel shown
      in Schedule 5.1 to perform Applications Development services, and Business
      Consulting services (collectively, "Base Services') at CalPX's offices in

               (i)  the Program Management Services described in Part A of
                    Schedule 3.1;

3.2  Semice .&e1s.

     (a)  In the absence of adequate historical data from the operation of
          Ca1PX's Systems, the parties agree to use the service levels set forth
          in Schedule 3.2 ("Service Levels") for the Services. These Service
          Levels have been selected based upon industry data and a partial
          analysis of the operation of CalPX's Systems and the number of PSC
          Personnel assigned to perform the Services. During the first 120 days
          after the Effective Date ("Transition Period"), Perot Systems and
          CalPX shall diligently and in good faith negotiate any changes to the
          Service Levels that are required to reflect the actual operation of
          CalPX's Systems during the six-month period prior to the Effective
          Date. After the Transition Period, Perot Systems shall meet or exceed
          the mutually agreed Service Levels with respect to the Services. The
          addition of any Service Level not set forth on Schedule 3.3 as of the
          Effective Date shall require an amendment to this Agreement.

     (b)  Perot Systems shall be excused from its obligation to perform the
          Computer Operations Services in accordance with the Service Levels to
          the extent that it can not meet such Service Levels as a result of
          actions or failures to act by CalPX in 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  Addition1 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 Pmeediure.

     (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) the Account Manager shall
          give the Change Review Board prompt notice (which may be given orally,
          provided that any oral notice is confirmed in writing within five
          business days) of any Change made as necessary on an emergency basis.

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

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

                                        8

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

         (e)      Within ten business days (or such longer period as is mutually
                  agreeable) after receiving a request from CalPX for a Change
                  Order, Perot Systems shall prepare and provide to CalPX's
                  Representative or the Change Review Board a document
                  summarizing the effect, if any, of the proposed Change on (i)
                  the development schedule, including but not limited to CalPX's
                  obligations under the development schedule, (ii) the
                  functionality and requirements of the applicable System to be
                  delivered, and (iii) the development budget. In addition,
                  Perot Systems shall inform CalPX regarding any other business
                  impact that Perot Systems believes to be relevant to an
                  evaluation of the Change Order. The CaIPX 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 with- draw the
                  request for such Change Order. CaIPX's failure to approve,
                  reject or withdraw the request within the applicable time
                  period shall be deemed a withdrawal of such request.

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

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


                                        9


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

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

3.6      Management Procedures Manual- On or before the end of the Transition
         Period and as part of the Services, (I) 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 the
         operations or procedures described therein within a reasonable time
         after such changes are made.

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

3.8      Improved Technology. As part of the Services, Perot Systems shall
         provide CalPX with information about, and recommendations regarding,
         information technology developments that could reasonably be expected
         to have a favorable impact on CaIPX's information technology operations
         for CaIPX'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 aw and Reguilations.

         (a)      Perot Systems shall identify and notify CaIPX 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
                  CaIPX 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 perforning its obligations under this Agreement, Perot
                  Systems shall (i) use commercially reasonable efforts to
                  continue to perform the Services and (ii) develop and, upon
                  CalPXs 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     Cuistomer Satkfaction.

         (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 CaIPX site. The survey shall contain questions to be
                  agreed upon by CalPX and Perot Systems no later than 30 days
                  before the date on

                  which the survey is scheduled to begin. Perot Systems shall
                  promptly share the 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, Ca1PX may initiate at
                  its expense a third- party review of the Services being
                  performed by Perot Systems. If CaIPX 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     Regilar mprovement. 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.

                  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

                  any Services that Perot Systems cannot perform in a manner
                  that is reasonably satisfactory to both parties.

4.3      Access to Cla1PX Facilities. CaIPX 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

         and facsimile machines), supplies, and duplicating services as Perot
         Systems may reasonably require in connection with the activities

                  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

         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      Peifirmance Bonimes anti Credit .

         (a)      CalPX and Perot Systems have established the "Baseline Budget"
                  set forth in Schedule 5.1, which represents CaIPX'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    Reimbuirsahle 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 CaIPX 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 Adjistment. 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 CaIPX 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 CaIPX Chief
      Financial Officer. CalPX shall deliver a CalPX check to the Account
      Manager at CaIPXs 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 CaIPX each month in support of its charges under this
       Agreement, including reimbursable expenses. Upon notice from CalPX, Perot
       Systems shall provide CaIPX and its representatives (collectively, the
       "CaIPX 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-Throu1gh Fxpences. 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 CaIPX for such IT vendor
       invoices, together with Perot Systems' recommendation for payment,
       nonpayment, or partial payment, to CalPX twice per month on or about the
       fifth and twentieth days of the month for CalPX's review and payment.
       CaIPX 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  Adjuclstment of Budget.

       (a)    During any 12-month period commencing as of the Effective Date,
              CaIPX 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 CaIPX may not
         exercise such right to reduce the Baseline Budget until after the
         Transition Period and Required Improvements are completed. If during
         any three calendar month period commencing after the Transition Period
         and the Required Improvements are completed the average number of
         transactions settled through CalPX's settlement system during such
         three-month period is less than 50% of the average number of
         transactions settled through CalPX's settlement system during the
         Transition Period, CalPX and Perot Systems shall negotiate appropriate
         adjustments to the Baseline Budget, the number of Full-Time Equivalent
         PSC Personnel providing Core Services, the Service Levels, and Schedule
         7.8 provided that the reduction in the number of transactions settled
         is the result of circumstances outside CaIPX's reasonable control.

(b)      If CalPX elects to reduce the Baseline Budget as provided in Section
         5.1 0(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 the Baseline Budget, Perot Systems shall have the right to reduce
         the number of Full-Time Equivalent PSC Personnel performing Core
         Services under this Agreement, and Perot Systems and CalPX shall adjust
         the Service Levels and Schedule 7.8 as appropriate to reflect the

         (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). Ca1PX 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

         a calendar month basis and shall be prorated for any partial month.

         either party by the other pursuant to this Agreement shall be paid to
         the applicable party within 30 days after the expiration or termination

                  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

                  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

                  verbal statements summarized in writing within 10 business
                  days, (ii) printed and electronic forms, (iii) handwritten

                  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 Dlisclosuires. 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

                                       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,

                  disclosed by reason of legal, accounting or regulatory
                  requirements beyond the reasonable control of the receiving
                  party.

         (e)      Ohligations upon Termination or xIpiratinn. Promptly after the
                  expiration or termination of this Agreement, except as

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

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

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

6.4      Perot Systems Software and Perot Systems Tools.

         (a)      Any software that is proprietary to Perot Systems that Perot
                  Systems uses or to which Perot Systems provides CalPX access
                  ("Perot Systems Software") and any tools or methodologies
                  which are proprietary to Perot Systems and used in connection
                  with the activities contemplated by this Agreement ("Perot
                  Systems Tools"), including any modifications to any Perot
                  Systems Software or Perot Systems Tools, shall be and remain
                  the property of Perot Systems, and Ca1PX shall have no rights
                  or interests therein, except as otherwise provided in this
                  Agreement.


                                       22

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

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

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

                  limited to all trade secrets, copyrights, patents and other
                  intellectual property rights in and to such Work Product.
                  Except as otherwise agreed in this Article 6, Perot Systems
                  hereby irrevocably assigns, transfers and conveys, and shall
                  cause all PSC Personnel to assign, transfer and convey, to
                  CalPX without further consideration all of its and their

                  own names such intellectual property rights in and to the
                  Perot Developed Software and related Documentation. CalPX
                  agrees to execute any documents or take any other actions as

                           the Work

                                       24

                    Product is being developed and for a period of one (1) year

             grants to CalPX the license rights referred to in paragraph (b)
             above, provided that if any Embedded Software is owned by a third
             party, then the terms of the applicable license shall define each
             party's rights to such Embedded Software.

       (a) CalPX acknowledges that, prior to the Effective Date, Perot Systems
           has acquired, conceived, developed or licensed, and after the
           Effective Date shall continue (both independently and as a result of
           performing services under this Agreement) to acquire, conceive,
           develop or license, certain architectures, concepts, industry
           knowledge, techniques and template works of authorship which embody
           copyrights, inventions, trade secrets and other intellectual property
           (collectively, "Know-How") relating to the types of services to be
           performed for CaIPX under this Agreement. CalPX desires Perot Systems
           to apply its Know-How in connection with the Services, and
           acknowledges that performance of the Services shall enhance and
           expand the Know- How. Accordingly, Perot Systems may (1) develop or
           distribute products or perform services similar to the Work Product

           Know-How to develop or distribute products or to perform services for
           any other person, provided that (i) no such activity violates the
           other provisions of this Article 6, (ii) the Know-How does not
           contain any Confidential Information of CalPX and (iii) use of the
           Know-How does not misappropriate any trade secret rights or infringe
           upon any other copyright, patent or other proprietary rights of

           those covered by patents and patent applications at any time) and
           (ii) the copyright in any templates that form the basis for the Work
           Product (but not the copyright in the Work Product derived from the
           template).




                                       25

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

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

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

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

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





                                             26

             arbitration may be entered in any court of competent jurisdiction.

7.4   Terminatinn for Caise. If either party (i) breaches any of its material
      obligations under this Agreement (excluding CaIPX'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.

      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 Ca1PX 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 CaIPX'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)

             participate in any plans, arrangements, or distributions by CalPX

              Acceptance Test Period with notice of the 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, Ca1PX 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.

                                     SCHEDULE 3.3
                                     Service Levels

A.    Service L evels - General Provicions

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.

       Assuimptions 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 I







                                      

            of its manufacturer, (iii) to interoperate properly with other
            hardware or software authorized to be replaced by CalPX, 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.

   Perot Systems shall target the evaluation of systems management products and
   tools for use by the Computer Operations team to efficiently monitor and
   manage the multiple platforms used in the CalPX environment. Once product
   selection is completed, an implementation of the targeted environment must be
   planned and executed. This includes customization and integration of the
   Problem Management and Change Management packages.

   Estimated PSC Personnel Requirements above Baseline: 9 FTE-months

3. NT Service Pack

   All Managed Equipment running the Microsoft Windows NT operating system must
   be upgraded to NT Service Pack 6A.

   The current NT environment is at the NT Service Pack 4 plus hot fixes. A
   project to implement the new service into each cluster discretely must occur
   to resolve known problems with memory leaks and other technical fixes.

   Estimated PSC Personnel Requirements above Baseline: None



                              Schedule 4.5 - Page I











4. Remedy Customization/Inplementation/Training

   The Remedym software that Perot Systems uses for problem and change
   management must be customized to support the CalPX's specific requirements.
   In addition, the escalation process used to support the Ca1PX's business must
   be automated.

   This process shall improve the notification and response of technicians when
   warning or alerts are issued by Systems.

   After the RemedyTm software is customized, it must be implemented in the
   CalPX's environment to provide access to all authorized PSC Personnel,
   including Transitioned Employees, and all authorized CalPX personnel. Each of
   the authorized users must be trained to use this software.

   This process shall improve the notification and response of technicians when
   warning or alerts are issued by Systems.

   Estimated PSC Personnel Requirements above Baseline: None

5. HP Firmware Updates

   All Hewlett-Packard servers and system components must be inventoried to
   determine its current firmware version and, if necessary, upgraded to the
   most current firmware version that is commercially available.

   Upgrading to the latest firmware versions may resolve issues such as data
   corruption, missing interrupts and lost data chains. In addition, these
   upgrades should increase reliability and availability. Perot Systems shall
   manage HP to complete this Required Improvement under the current agreement
   between CalPX and HP.

   Estimated PSC Personnel Requirements above Baseline: None

6. Review Backup and Archive Strategies

   Ca1PX backup and archive strategies must be reviewed and updated, if
   necessary.

   Perot Systems shall review the CaIPX's requirements for application and data
   backup and archival. The methods and tools currently being used to meet these
   requirements must be reviewed for compliance.

   As appropriate, Perot Systems shall specify changes in these requirements,
   methods and tools to manage these requirements more effectively across the
   CaIPX's Systems. Perot Systems shall review with CalPX the work that must be
   done to establish the most appropriate frequency and methodology to meet
   CalPX's data recovery requirements.



                              Schedule 4.5 - Page 2














   Estimated PSC Personnel Requirements above Baseline: None

7. Implement Program/Project Management Office

   CaIPX must implement and use the Program Office/Project Management processes
   and procedures to effectively manage programs and projects.

   Estimated PSC Personnel Requirements above Baseline: None

8. Implement Change Management Methodology

   CalPX must implement the Change Control Procedure for all proposed Changes.
   CalPX must also implement the Change Control Board and the IT Steering
   Committee.

   Estimated PSC Personnel Requirements above Baseline: None

9. Add CalPX IT Operations to Automated Call Distributor (ACD)

   The Automated Call Distributor (ACD) system used by Perot Systems must be
   used to manage the help desk.

   This system must be implemented to provide the capability to efficiently
   distribute calls throughout the enterprise and report the call volumes,
   service time, queue time, and average talk time. These metrics are critical
   when forecasting future operational service levels and requirements. As part
   of implementing this Improvement, Perot Systems shall manage CalPX vendor to
   implement the required improvement.

   Estimated PSC Personnel Requirements above Baseline: None

10. Plan and Implement Consolidated Test Environment

   The physical architecture that shall support the testing environment and the
   required software and tools necessary to manage production promotion from one
   environment to the next (i.e. development to test, test to model office and
   model office to production) must be planned, designed and implemented. Also
   included in this Required Improvement is planning and implementation of
   configuration management/release procedures and the required tools. Test
   procedures that describe how applications are to be tested and promoted
   through the testing environments, server code, database objects, CalPX based
   applications and the tracking of application source code must also be
   developed and implemented.

   Estimated PSC Personnel Requirements above Baseline: 16 FTE-months.

                         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.

                                    PROCEDTTRFS

    DfOCUJMENTATION

    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 inclnde 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.

    APPROVAL S



                              Schedule 5.4 - Page I










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.

    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.

   to the gasoline options offered with the rental car.

   The California Power Exchange carries liability and vehicle damage insurance
   that protects the CaIPX 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 Ca1PX business, the employee
   must contact the Chief Financial Officer and Controller immediately so that
   claims may be processed with the CaIPX 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.

      Rusiness 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

    and testify at arbitration hearings. If no petitions are received from
    intervening third parties within said thirty (30) day period, the case will
    move forward in accordance with Section 10 of the Procedures. Petitions to
    intervene shall be in writing and shall set forth the grounds of the
    proposed intervention, the position and interest of the petitioner in the
    proceeding, and whether petitioner's position is in support of or opposition
    to the relief sought in the notice. Petitioners for intervention also shall
    pay the appropriate filing fee if the intervention is challenged.

        Upon receipt of a petition to intervene from any third party, the AAA
    will invite the comments of the original parties set forth on the notice. If
    no objection is raised within fourteen (14) days to the petitions of the
    intervening third parties, the petitioners shall be allowed to participate
    as requested and the case will move forward in accordance with Section 10 of
    the Procedures.

                              Schedule 7.3 - Page 4











        If any timely objection is received to any petition for intervention,
    the AAA will appoint one neutral intervention arbitrator, without the
    submission of lists, to consider the petitions and objections and to make a
    binding determination regarding the participation of the party or parties
    requesting to intervene. The intervention arbitrator will be subject to the
    disclosures required by Section 11 of the Procedures.

        Upon confirmation of the appointment of the intervention arbitrator, the
    AAA will deliver to him or her the relevant petitions and objections
    thereto, and the intervention arbitrator will render a written decision
    within fourteen (14) days of receipt of those documents, without oral
    hearings. The arbitration shall, upon good cause shown, grant the
    petition(s) for intervention provided that the issues in the arbitration
    will not be unduly broadened or the arbitration unduly extended. The
    intervenors may only participate to the extent authorized by the
    intervention arbitrator. The case will then move forward in accordance with
    Section 10 of the Procedures. The intervenor(s) shall file a statement of
    claim, pay the appropriate filing fee and share in the costs associated with
    the arbitration in an amount to be determined by the arbitrator(s) appointed
    to hear the case.

10.   Selection of the Arbitrator(s)

        Disputes Under $1,000,000 Where the total amount of the claims and
    counterclaims in controversy is less than $1,000,000 (exclusive of legal
    costs and interest), the disputing parties shall select within fourteen (
    14) days an arbitrator from a list containing the names of at least ten (10)
    individuals with arbitration experience, or with technical or business
    experience in the electric power industry, or both. The AAA shall supply the
    list following expiration of the intervention period, submission of the
    formal demand for arbitration and payment of any appropriate filing fees. If
    the parties cannot agree upon an arbitrator within the stated time, the
    parties shall take turns striking names from the list of proposed
    arbitrators. The first party to strike a name shall be determined by
    lottery. The last name remaining on the list shall be designated the
    arbitrator.

        Disputes of $1,000,000 or More Where the total amount of claims and
    counterclaims in controversy is $1,000,000 or more (exclusive of interest
    and legal costs), the disputing parties may (a) agree on any person to serve
    as a single arbitrator, or (b) shall endeavor in good faith to agree within
    fourteen (14) days on a single arbitrator from a list of ten (10)
    individuals with arbitration experience, or with technical or business
    experience in the electric power industry, or both. The AAA shall supply the
    list following expiration of the intervention period, submission of the
    demand for arbitration and payment of any appropriate filing fees. If the
    parties are unable to agree on a single arbitrator within the stated time,
    the party or parties demanding arbitration shall designate one arbitrator
    and the party or parties responding to the demand for arbitration shall
    designate one arbitrator, in both cases

                              Schedule 7.3 - Page 5









    from the AAA's list of arbitrators no later than the tenth (1 e) day after
    the expiration of the stated time (the intervention arbitrator shall
    determine the position of intervenors for the purposes of arbitrator
    selection). The two arbitrators so chosen shall choose a third arbitrator
    from the AAA's list of arbitrators.

11.   Disclosures Required of Mediators and Arbitrators

    The designated mediator or arbitrator(s) shall be required to disclose to
    the parties any circumstances which might preclude them from acting in an
    objective and impartial manner. Each mediator or arbitrator shall disclose:

          (a)  any direct financial or personal interest in the outcome of the
               mediation or the arbitration;

          (b)  any information required to be disclosed by the California Code
               of 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
               to disclose interests, relationships, or circumstances that might
               preclude a 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 petitioner(s) 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 arbitrator(s) 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 parties. Alternatively, the parties may, by written agreement,
     modify the standard procedures. In the event of a disagreement between the
     arbitrator(s) and the written agreement of the parties regarding
     arbitration procedures to be utilized, the parties' written agreement shall
     prevail.

13.  Remedies

     (a)  "Baseball" Arbitration If all of the parties agree to conduct the
          arbitration "baseball" style, each party shall submit to the
          arbitrator(s) and exchange with each other their last best offers in
          the form of the award they believe the arbitrator(s) should make, not
          less than seven (7) days in advance of the date fixed for the hearing,
          or such other date as the arbitrator(s) may decide. If a party fails
          to submit its last best offer in accordance with this Section, that
          party shall be deemed to have accepted the offer proposed by the other
          party. The arbitrator(s) shall be limited to awarding only one of the
          proposed offers, and may not detennine an alternative or compromise
          remedy.

     (b)  Arbitrator's Discretion Unless all of the parties agree to conduct the
          arbitration "baseball" style, the arbitrators shall have the
          discretion to grant the relief sought by a party, or determine such
          other remedy as is appropriate. Unless otherwise expressly limited
          herein, the arbitrators shall have the authority to award any remedy
          or relief available from FERC, or any court of competent jurisdiction.
          Where any PX Document allows the parties to reach an agreement on a
          matter at some future time and provides that defaults or disputes
          shall be referred to the PX ADR Procedures, the arbitrator(s) shall
          make a decision on the matter considering what is fair and reasonable
          in light of the circumstances.

14.   Summary Disposition

       The arbitrator(s) shall dispose in a summary manner a statement of claim,
       response to a statement of claim, counterclaim, demand for arbitration or
       a

                              Schedule 7.3 - Page 7










       response to a demand for arbitration that in the reasoned opinion of the
       arbitrator(s) does not have a good faith basis in either law or fact. If
       the arbitrator(s) make a determination that there is no good faith basis
       in either law or fact, the arbitrator(s) shall have discretion to award
       the costs of the time, expenses, and other charges of the arbitrator(s)
       to the prevailing party. A determination made under this Section (a) may
       be made any time after the review and consideration by the arbitrator(s)
       of the parties' briefs, which may be before a hearing is held on the
       matter and (b) is subject to appeal under the Tariff.

15.    Discovery Procedures
       Adequate provision for the discovery of relevant facts, including the
       taking of testimony under oath, production of relevant documents and
       other things, the presentation of evidence, the taking of samples,
       conducting of tests, and inspection of land and tangible items shall be
       granted by the arbitrator(s). When deciding the nature and extent of such
       discovery, the arbitrator(s) shall take into account (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,
       and (d) the amount in controversy. Discovery disputes shall be resolved
       by the arbitrator(s) by telephonic means or other means determined by the
       arbitrator(s).







                              Schedule 7.3 - Page 8





16.    Evidentiary Hearing
       An evidentiary hearing with provision for the examination and
       cross-examination of witnesses shall be conducted unless all parties
       consent in writing to the resolution of the matter on the basis of the
       written record. The forms and methods for taking evidence shall be
       determined by the arbitrator(s) and may be modified pursuant to Section
       12 of the Procedures. The arbitrator(s) may require such written or other
       submissions from the parties as deemed appropriate by the arbitrator(s),
       including submission of direct and rebuttal testimony of witnesses in
       written form. The arbitrator(s) may exclude any evidence that is
       irrelevant, immaterial, unduly repetitious, unduly prejudicial or
       privileged. The arbitrator(s) shall compile a complete evidentiary record
       of the arbitration hearing (that may include a summary of testimony
       presented and the briefs, affidavits and exhibits submitted), which shall
       be available to the parties upon request on completion of the
       arbitration.

17.    Confidentiality
       Subject to the other provisions of the Procedures, any party may claim
       that information contained in a document otherwise subject to discovery
       is "confidential" if such information would be so characterized under the
       Federal Rules of Evidence. The party making such claim shall provide to
       the arbitrator(s) in writing the basis for the assertion. If the claim of
       confidentiality is confirmed by the arbitrator(s), they shall establish
       requirements for the protection of such documents or other information
       designated as "confidential" as may be reasonable and necessary to
       protect the confidentiality and commercial value of such information. Any
       party disclosing information in violation of these provisions or
       requirements established by the arbitrator(s), unless such disclosure is
       required by federal or state law or by a court order, shall thereby (a)
       waive any right to introduce or otherwise use such information in any
       judicial, regulatory, or other legal or dispute resolution proceeding,
       including the proceeding in which the information was obtained and (b) be
       subject to monetary sanctions by the arbitrator(s) and injunctive relief
       in a court of competent jurisdiction.

18.    Timetable:
       Promptly after appointment, the arbitrator(s) shall set a date for the
       issuance of the arbitration decision, which shall be within six (6)
       months (or such earlier date as the parties and the arbitrator(s) may
       agree) from the date of their appointment, with other dates, including
       the dates for an evidentiary hearing or other final submissions of
       evidence, set in light of this date. The date for the evidentiary hearing
       or other final submission of evidence may be extended by the reasonable
       discretion of the arbitrator(s). The arbitrator(s) shall have the power
       to impose sanctions, including dismissal of the proceeding, for dilatory
       tactics or undue delay in completing the arbitration proceedings.


                              Schedule 7.3 - Page 9











19.   Decision

       (a)    Except as provided below with respect to the "baseball" style
              arbitration, the arbitrator(s) shall issue a written decision (and
              a summary suitable for publication by the PX) granting the relief
              requested by one of the parties, or such other remedy as is
              appropriate, if any, and shall include findings of fact and law.
              The arbitrator'(s) decision shall be based on the evidence in the
              record and the terms of PX Documents, as applicable, and shall
              consider (and not violate) applicable substantive United States
              federal law, including the FPA, and any applicable FERC
              regulations and decisions or applicable substantive state law.
              Additionally, the arbitrator(s) may consider relevant decisions in
              previous arbitration proceedings. A summary of the disputed matter
              and the decision of the arbitrator(s) shall be published in the PX
              newsletter or electronic bulletin board, or any other method
              adopted by the PX ADR Committee, and maintained by the PX.

       (b)    In an arbitration conducted "baseball" style, the arbitrator(s)
              shall issue a written decision adopting one of the awards proposed
              by the parties, and shall include findings of fact and law. The
              decision of the arbitrator(s) shall be based upon the evidence in
              the record and the terms of PX Documents, as applicable, and shall
              consider (and not violate) applicable substantive United States
              federal law, including the FPA, and any applicable FERC
              regulations and decisions or applicable substantive state law. If
              the arbitrator(s) conclude that no proposed award is consistent
              with the factors enumerated in the evidence in the record and the
              terms of PX Documents, as applicable, or with the applicable
              substantive United States federal law, including the FPA, and any
              applicable FERC regulations and decisions or with the applicable
              substantive state law, or address all of the issues in dispute,
              the arbitrator(s) shall specify how each proposed award is
              deficient and direct that the parties submit new proposed awards
              that cure the identified deficiencies. A summary of the disputed
              matter and the decision of the arbitrator(s) shall be published
              within thirty (30) days in the PX newsletter or electronic
              bulletin board, or any other method adopted by the PX ADR
              Committee. An award shall not be deemed to be precedential.

       (c)    Where a three-person panel of arbitrators is appointed pursuant to
              Section 10 of the Procedures, at least two of the arbitrators must
              agree on the decision.



20.   Compliance


                             Schedule 7.3 - Page 10










       Unless the decision of the arbitrator(s) is appealed to FERC or a court
       of competent jurisdiction, the disputing parties shall, upon receipt of
       the decision, immediately take whatever action is required to comply with
       the award to the extent the award does not require regulatory action. An
       award that is not appealed shall be deemed to have the same force and
       effect as an order entered by the FERC or any court of competent
       jurisdiction.

21.   Enforcement
       Following the expiration of the time for appeal of an award, any party
       may apply to FERC or any court of competent jurisdiction for entry and
       enforcement of judgement based on the award.

22.    Costs
       Subject to the adjustment pursuant to Section 9 with respect to third
       party intervention, the costs of the time, expenses, and other charges of
       the arbitrator(s) shall be borne by the parties to the dispute, with each
       side on an arbitrated issue bearing its pro-rata share of such costs, and
       each party to an arbitration proceeding bearing its own costs and fees.
       If the arbitrator(s) determine that a demand for arbitration or response
       to a demand for arbitration was made in bad faith, the arbitrator(s)
       shall have the discretion to award the costs of the time, expenses, and
       other charges of the arbitrator(s) to the winning party. Notwithstanding
       the above, at the discretion of the arbitrator(s), the winning party in
       any dispute which has resulted in the enforcement of an important right
       affecting the public interest shall not be required to pay any of the
       costs of the arbitrator(s) and may recover such of its own reasonable
       attorney fees, expert witness fees, and other reasonable costs from the
       losing party to the dispute if (a) a significant benefit, whether
       pecuniary or non-pecuniary, has been conferred on the general public, (b)
       the necessity and financial burden of private enforcement are such as to
       make the award appropriate and (c) such fees should not, in the interest
       of justice, be paid out of the recovery. The parties should be aware of
       Rules 48-51 of the AAA's Commercial Arbitration Rules and pages 13-14 of
       the AAA's Commercial Mediation Rules regarding costs. A complete fee
       schedule is attached to the Procedures.

23.   Appellate Record
       The parties intend that FERC or the court of competent jurisdiction
       should afford substantial deference to the factual findings of the
       arbitrator(s). No party shall seek to expand the record before the FERC
       or court of competent jurisdiction beyond that assembled by the
       arbitrator(s), except (a) by making reference to legal authority which
       did not exist at the time of the decision of the arbitrator(s), or (b) if
       such party contends the decision was based upon or affected by fraud,
       collusion, corruption, misconduct or misrepresentation.

24.   Appellate Procedures

                             Schedule 7.3 - Page II










       (a)    If a party to an arbitration desires to appeal an award, that
              party shall provide a notice of appeal to the PX and all parties
              within fourteen (14) days following the date of the award. The PX
              shall publish within fourteen (14) days' notice of the appeal in
              the PX newsletter or electronic bulletin board, or any other
              method adopted by the PX ADR Committee. Within ten (10) days of
              filing the notice of appeal, the appellant must file an
              appropriate application, petition or motion with FERC to trigger
              review under the FPA or with a court of competent jurisdiction.
              Such filing shall state that the subject matter had been the
              subject of arbitration pursuant to the Tariff.

       (b)    Within thirty (30) days of the notice of appeal (or such other
              period as FERC or the court of competent jurisdiction may specify)
              the appellant shall file the complete evidentiary record of the
              arbitration and a copy of the award with FERC or with the court of
              competent jurisdiction. The appellant shall serve copies of a
              description of all materials included in the submitted evidentiary
              record on the PX and all parties.

       (c)    Implementation of the award shall be deemed stayed pending an
              appeal unless and until, at the request of a party, the FERC or
              the court of competent jurisdiction to which an appeal has been
              filed issues an order dissolving, shortening, or extending such
              stay. However, a summary of each appeal shall be published in the
              PX newsletter or electronic bulletin board, or any other method
              adopted by the PX ADR Committee.

       (d)    FERC orders resulting from appeal shall be subject to judicial
              review pursuant to the FPA.

       of signatures as established by the PX Tariff.

2.     Arbitration Services. AAA's Commercial Arbitration administrative fees
       are based on the amount of the claim or counterclaim. Arbitrator
       compensation is additional. Unless the parties agree otherwise,
       arbitrator compensation and administrative fees are subject to allocation
       by the arbitrator in the final award. Services in respect of intervention
       requests shall be paid pursuant to Section 3 of this ExhibitA.

a.     Filing Fees. A nonrefundable filing fee is payable in full by the filing
       party when a claim, counterclaim or additional claim is filed, as
       follows:

                     Above $1,000,000 to $5,000,000            7,000.00

              When no amount can be stated at the time of filing, the minimum
              fee is $2,000, subject to increase when the claim or counterclaim
              is disclosed. The minimum filing fee for any case having three
              arbitrators is $2,000. When a claim or counterclaim is not for a
              monetary amount, AAA shall determine an appropriate filing fee.


                             Schedule 7.3 - Page 13










              The administrative fee for claims in excess of $5,000,000 will be
              negotiated with the parties to the dispute.

              The expedited procedures outlined in sections 53-57 of the
              Commercial Arbitration Rules (as modified herein) shall apply in
              any case where no disclosed claim or counterclaim exceeds $50,000,
              exclusive of interest and arbitration cost. Those procedures
              provide for arbitrators to be directly appointed by AAA. If the
              parties desire to chose an arbitrator as provided in Section
              7.3.1.1 of the PX Tariff, a service charge of $150 will be payable
              by each party.

       b.     Hearing Feel. For each day of hearing held before a single
              arbitrator, an administrative fee of $150 is payable by each
              party. For each day of hearing held before a multi-arbitrator
              panel, an administrative fee of $250 is payable by each party.
              There is no AAA hearing fee for the initial Procedural Hearing.
              There is no hearing fee for the initial hearing in cases in which
              no party's claim exceeds $10,000, administered under the expedited
              procedures, but the arbitrator's compensation shall be split by
              the parties (hourly rate of compensation will vary depending upon
              the arbitrator selected).

       c.     Postponement/Cancellation Fees. A fee of $150 is payable by a
              party causing a postponement of any hearing scheduled before a
              single arbitrator. A fee of $250 is payable by a party causing a
              postponement of any hearing scheduled before a multi-arbitrator
              panel.

       d.     usnpension for Nonpayment. If arbitrator compensation or
              administrative charges have not been paid in full, the
              administrator may so inform the parties in order that one of them
              may advance the required payment. If such payments are not made,
              the arbitrator or arbitrator panel may order the suspension or
              termination of the proceedings. If no arbitrator has yet been
              appointed, the administrator may suspend the proceedings.

3.     Intervention Services. There will be no additional charge if an
       intervention request is not challenged. If the request for intervention
       is challenged by a party to the dispute, the following fee schedule shall
       apply:

       o      Each challenger and each challenged intervenor shall pay a $150
              fee (even if parties make joint filings)

       o      pUs compensation per hour for the arbitrator split between the
              intervenor(s) being challenged and the challenger(s) (compensation
              rate will vary depending upon the arbitrator selected)

       o      pis $75 surcharge per hour of arbitrator compensation split by the
              intervenor being challenged and by the challenger(s) (to cover AAA
              administrative costs).

                             Schedule 7.3 - Page 14











       o      If the arbitrator finds that an intervention request or challenge
              was made in bad faith or for purposes of delay, the arbitrator
              shall have discretion to assess all of the fees and costs related
              to the intervention arbitration to the other party.

       o      After an intervention request has been granted, the intervenor
              shall file a statement of claim. If the intervenor seeks separate
              monetary relief the intervenor shall pay the filing fee set forth
              in Section 2 of this Fxhihit A with respect to arbitration issues.
