Re: California Independent System Operator

Dear Marty:

As we discussed during our recent meeting with Mr. Jeffrey Tranen of the
California Independent System Operator, Inc. (ISO) and Mr. Ronald Nash of Perot
Systems Corporation ("Perot Systems"), I am enclosing for your review the
following documents:

     1.  A "Disclaimer" proposed to be used in Perot Systems' sales and
         marketing presentations involving the California energy market
         deregulation.

     2.  A "Letter" proposed to be sent to potential participants in the
         California energy market to whom Perot Systems has made sales
         and marketing presentations.

     3.  An "Ethics Wall" proposed to be invoked formally for Perot Systems
         associates working with the ISO.

In response to Mr. Tranen's inquiry, Perot Systems has made presentations
regarding our consulting capabilities with respect to California market
restructuring to three potential market participants (in addition to related
presentations made to the ISO and the California Power Exchange). Of these
three companies, two decline to reveal their identities under the terms of our
non-disclosure agreements. The remaining company is San Diego Gas and Electric,
and its parent, Energy Pacific, which has informed the ISO of our confidential
discussion.

In response to Mr. Tranen's inquiry regarding our relationship with Policy
Assessment Corporation (PAC), I have reviewed our contracts database and made
appropriate inquiries regarding any such relationship. Perot Systems has no

contractual relationship with PAC, except for mutual non-disclosure agreements.
Perot Systems and PAC make periodic joint sales presentations in situations
where we have mutual business interests, and we have discussed various
potential joint projects. However, we have not yet engaged in any joint
projects and none are currently pending. Perot Systems has not provided any
services to PAC, but has received consulting services from PAC. In addition,
PAC does not employ any current or former associates of Perot Systems.

Upon your approval of the forms of these documents, Perot Systems will promptly
(i) formally communicate the content of the Ethics Wall to the appropriate
associates, (ii) send the Letter to each of potential participants to whom
Perot Systems has made sales and marketing presentations regarding our
consulting capabilities with respect to California market restructuring, and
(iii) ensure that the Disclaimer appears as part of our sales and marketing
presentations regarding our consulting capabilities with respect to California
market restructuring.

Based on our discussions of November 18th, and following our compliance with
Mr. Tranen's requests in this matter, it is our understanding that the ISO will
make similar requests to each of the ISO's vendors who offer consulting
services relating to California market restructuring and that Mr. Tranen will
formally withdraw the allegations made in his letter dated October 22, 1997.

If you have any questions regarding these matters, please call me at
972/383-5615 at your earliest convenience. Best wishes for the holidays.

Sincerely,

/s/ CHARLES N. BELL

                           PROPOSED DISCLAIMER SLIDE

Perot Systems' services addressing the restructuring of California's power
markets and development of supporting infrastructure and services are based on
our understanding of the California ISO's and PX's business protocols; NOT the
use of, or knowledge of, any proprietary client systems.



Proposed Letter to Contacts:

The California Independent Service Operator (ISO) has retained Perot Systems
Corporation (Perot Systems) as a member of the ISO Alliance, LLC to provide
professional services to the ISO in the design, development, integration and
roll-out of the information technology applications supporting the ISO's
business operations.

Recently, the ISO expressed concerns over the potential insights which Perot
Systems and the ISO's other service providers may possess into its proprietary
systems or operations.

To address these concerns and avoid any suggestion, whether real or perceived,
of Perot Systems using information not in the public domain in performing
services to other clients, Perot Systems agreed to initiate several actions,
including contacting its present clients and those prospects with whom we have
been discussing matters of California market restructuring to reinforce our
position in matters of this nature.

I am writing to you in support of these agreements.

Perot Systems' offering of our services addressing the restructuring of
California's power markets and development of supporting infrastructure and
services, are based on our understanding of the ISO's and the California
Exchange's business protocols; not the use of, or knowledge of, any proprietary
client systems.

We are fortunate to count amongst the members of our team, subject matter
experts in such issues as congestion theory and in other equally critical
aspects of the business rules governing these markets. It is through these
Associates' comprehension of the business rules and their applications to the
market that our strategic service offerings are shaped.

Perot Systems' Standards and Ethical Principals embody the highest concepts and
standards of honesty and integrity. Our values require that we operate with
absolute integrity and that each of our associates conduct themselves in a
manner that will bring credit to themselves, their families and the company at
all times. Each and every associate pledges his or her personal and
professional commitment to these principals and values. There are no exceptions.

It is understandable that the major changes all of us are facing in
deregulating this industry should be accompanied by states of anxiousness. Perot
Systems feels it important that our clients can be assured that one constant
they can expect is the measure of integrity with which we will approach their
business dealings. We welcome the opportunity to discuss these matters if you
have any concerns or questions whatsoever. We will be contacting each of you
directly to review any concerns which you may have.

These are exciting times. We look forward to working with you to shape the
future.

Sincerely,


                                   MEMORANDUM



To:   All Perot Systems Associates and Independent Contractors Engaged on the
      California ISO Account

Re:   California ISO Ethics Wall


Please review the attached document and return the attached Affirmation to me as
soon as possible. It is essential that you review this document carefully and
comply with its requirements.


If you have any questions, please give me a call.




                     CALIFORNIA INDEPENDENT SYSTEM OPERATOR
                                   ETHICS WALL

                                NOVEMBER 17, 1997


              THIS DOCUMENT REQUIRES YOUR IMMEDIATE CAREFUL REVIEW

The core concepts of Perot Systems Corporation's ("Perot Systems") Standards and
Ethical Principals are the highest standards of honesty and integrity. Our
values require that we operate with integrity and that each of our associates
conduct themselves in a manner that will bring credit to themselves, their
families and the company at all times.


California Independent System Operator, Inc. (the "Client") has engaged the ISO
Alliance, LLC (the "Alliance") to provide certain project management, system
development, system integration, system testing and training services in
connection with electric utility deregulation and the new competitive
environment in the California electric industry. Perot Systems is a member of,
and a subcontractor to, the Alliance and has certain contractual obligations to
the Alliance and our Client with respect to (1) the disclosure and use of the
Alliance's and our Client's confidential information and (2) the acceptance of
certain third party client engagements.

Perot Systems' Standards and Ethical Principals, as well as your Associate
Agreement, Independent Contractor Agreement, or Confidentiality and Proprietary
Rights Agreement, as the case may be, prohibit the disclosure or use of our
Client's confidential or proprietary business and technical information without
Perot Systems' and our Client's approval.

From time to time, you may be called upon to participate in discussions with the
California Power Exchange (the "PX"), one or more investor owned utilities, one
or more scheduling coordinators (including the PX when acting in such capacity),
vendors or other persons who may use or have another interest in the computer
systems or our Client. In addition, you should be aware than certain Perot
Systems associates may be engaged in marketing consulting or technology services
to these parties.

In order to ensure compliance with Perot Systems' Standards and Ethical
Practices and our contractual obligations to our Client and to avoid the
appearance of a conflict of interest, Perot Systems is formally establishing a
so-called "Ethics Wall" with respect to all associates who perform services for
our Client. This Ethics Wall will serve to reinforce, to the greatest extent
practicable, the care to be exercised by all associates involved in Perot
Systems' work for our Client, particularly when talking to persons who are
involved in Perot Systems' work for third parties who may have an interest in
our Client's confidential or proprietary information.


            ALL PEROT SYSTEMS ASSOCIATES AND CONTRACT PERSONNEL MUST
           CAREFULLY REVIEW AND COMPLY WITH THE FOLLOWING RESTRICTIONS
                         WHICH COMPRISE THE ETHICS WALL
