April 14, 2008 Dear Shareholder, The annual meeting of Edison International scheduled to be held on April 24, 2008 is quickly approaching. Your vote is extremely important, regardless of the number of shares of Edison International common stock that you own. The Edison International Board of Directors and Management recommend that you vote "FOR" the nominees for Directors listed in the Joint Proxy Statement and "FOR" the ratification of the appointment of the accounting firm. For reasons stated below and explained in the Joint Proxy Statement, the Edison International Board of Directors and Management recommend that you vote "AGAINST" the shareholder proposal requesting an advisory vote on executive compensation. o Our long-standing competitive compensation structure has aligned executive compensation with shareholder value, as indicated by our strong five-year cumulative total shareholder return. o Shareholders can more clearly express their concerns and have a greater impact on our compensation practices by communicating directly with our Investor Relations department, Board of Directors, or individual members of the Compensation and Executive Personnel Committee (the "Committee"). o The proposal would not provide the Board or its Committee with meaningful guidance as to the compensation structure or individual executive compensation payouts. o Because our executive compensation program is already strongly aligned with company performance, an advisory vote to ratify prior executive compensation is unnecessary, and could undermine the fundamental role of the Board and its Committee in formulating executive compensation principles and practices that reflect the interests of shareholders. Thank you for your continued support. Very truly yours, /s/ Barbara E. Mathews ______________________ Barbara E.
