                                  ATTACHMENT A
                             NONDISCLOSURE AGREEMENT

This Nondisclosure Agreement (the "Agreement") is entered into between
California Power Exchange (CalPX), OM Technology Energy Systems Corporation
("OMT"), and Perot Systems Corporation ("Perot Systems"), hereinafter referred
to as "Consortium Members" as of September 9, 1999.

CalPX, OMT and Perot Systems are parties to a Consortium Agreement dated as of
August 13, 1999 (the "Consortium Agreement"). In order for the parties to
discuss preparing and submitting to the Mountain West Independent Scheduling
Administrator ("MWISA") a proposal to build and operate a settlement system and
internet interface system ("Proposal") each party may need to disclose
confidential or proprietary information to the others regarding its business
activities and plans (the "Confidential Information"). Information disclosed by
a party shall be deemed Confidential Information without regard to whether it is
marked as confidential or identified in writing as confidential. The parties
agree to protect all other's Confidential Information disclosed during the
period commencing 30 days before the Effective Date and ending six months after
the Consortium Agreement expires or is terminated.

1.   Each party shall use at least the same degree of care, but no less than a
     reasonable degree of care, to avoid unauthorized disclosure or use of the
     other parties' Confidential Information as it employs with respect to its
     own Confidential Information of like importance. Receipt and disclosure of
     Confidential Information will be coordinated for the parties by:

       For CalPX:  John Flory
       For Perot Systems: Dariush Shirmohammadi
       For OMT:   Kjell Barmsnes

2.   No party has any obligation with respect to any Confidential Information
     which (a) was previously known by such party without obligations of
     confidentiality; (b) that party independently develops; (c) is or becomes
     publicly available without a breach of this Agreement by any party; or (d)
     is disclosed to it by a third party who is not required to maintain its
     confidentiality. The party claiming any of the above exceptions has the
     burden of proving its applicability.

3.   Each party may disclose Confidential Information only to its own officers,
     directors, and employees and to its consultants and advisors who reasonably
     need to know it. Each party shall be responsible to the others for any
     violation of this Agreement by its own officers, directors, employees,
     consultants or advisors.

4.   No party may print or copy, in whole or in part, any documents or other
     media containing any Confidential Information without the prior written
     consent of the other parties other than copies for its officers, directors,
     employees, consultants or advisors who are working on the matter. No party
     will remove or deface any notice of copyright, trademark, logo or other
     proprietary notice of the other parties appearing on any original or copy
     of the others' Confidential Information.

5.   Each party's Confidential Information shall remain its own property. Upon
     the request of another party, each party shall return all of the others'
     Confidential Information, or destroy it and provide the other parties with
     written certification of such destruction, except for archival and backup
     copies that are not readily available for use and business records required
     by law to be retained.

6.   If any party becomes legally obligated to disclose any of the other
     parties' Confidential Information, the party subject to the obligation
     shall notify the other parties in writing promptly and shall cooperate with
     the other parties at their expense in seeking a protective order or other
     appropriate remedy.

7.   Each party agrees that in the event of a breach or threatened breach by a
     party, including its officers, directors, consultants or employees, of the
     provisions of this Agreement, the non-breaching parties will have no
     adequate remedy in money damages and, accordingly, shall be entitled to
     seek an injunction against such breach, in addition to any other legal or
     equitable remedies available to it.

                                        2



8.   Each party is disclosing Confidential Information solely on an "AS IS"
     basis, with no warranties. The disclosing party will not be liable for any
     damages arising out of the use of Confidential Information disclosed
     hereunder.

9.   If any Confidential Information originating in the United States is
     authorized by this Agreement to be disclosed outside the United States, the
     receiving parties agree to ensure that it or any materials derived from it
     are not disclosed or communicated to any individual or entity in any
     country to which the export of such information is prohibited by U.S.
     export laws or regulations.

10.  This Agreement is governed by the laws of California without regard to its
     rules on conflicts of law. No party may assign its rights or obligations
     under this Agreement. No modification or waiver of any provision of this
     Agreement shall be effective unless in writing and signed by the party
     sought to be bound. The obligations of confidentiality under this Agreement
     is the entire agreement between the parties on nondisclosure of
     Confidential Information and supersedes all prior representations and
     agreements between the parties on that subject relating to the Proposal.
     This Agreement shall expire five years after the last receipt of
     Confidential Information by any party.
