[Edison International Institutional Shareholder]

SUBJECT: Shareholder Proposal on Shareholder Rights Agreement

Dear [Institutional Shareholder]

At this year's annual meeting on May 15, Edison International shareholders will elect all eleven directors and
vote on a shareholder proposal regarding the Company's shareholder rights agreement.  Edison International's
Board recommends a vote "against" the proposal, and asks that you carefully consider the arguments in this letter
and the proxy statement before making up your mind.

Edison International's Board, comprised of a substantial majority of non-management Directors, places great
importance on sound corporate governance to protect the investment of its shareholders. The Board has reviewed
our shareholder rights plan on a regular basis and continues to believe that the plan is in the best interests of
Edison International's shareholders.

Over the past two years, Edison International has been buffeted by the California energy crisis and adverse
changes in the markets it serves.  We have worked hard to weather these difficult times and restore value for our
shareholders - and we are succeeding.  Last year, among other things, we removed $2.2 billion in overall debt,
recovered most of our crisis-related power procurement costs and worked to persuade public officials to restore a
healthy regulatory framework for California utilities.  While we believe we are meeting our challenges, there is
more work to be done to restore fully our companies to financial health and creditworthiness.  Our Board believes
it is particularly important that it has the tools to deal with any coercive and unfair takeover attempts.  In
short, we believe that now is not the time to remove our shareholder rights plan.

In undertaking your analysis, we also ask that you consider the type of shareholder rights agreement enacted by
the Edison International Board.  Significantly, and unlike many other plans, Edison International's plan contains
the following shareholder-friendly features:

        o   Edison International's rights plan has a 20% trigger, not the more typical 15% trigger; and
        o   Edison International's rights plan does not contain a "dead hand" provision.

We hope this information will assist you in your deliberations, and we urge you to vote "against" the shareholder
proposal (Item 2 on your proxy card).  A complete statement of our position with respect to this proposal is
contained in our April 7, 2003 proxy statement at pages 44 and 45.
