The following e-mail was sent to all Edison International Employees on March 17, 2010:

Subject: Edison International Proxy Materials

To: Edison International Employees

Last Friday, I sent you an email to advise you that proxy materials for the 2010 annual meeting of shareholders are available on our Web site at: www.edison.com/annualmeeting. I also provided information regarding the Notice of internet availability of proxy materials that most shareholders will receive in the mail.

Shareholders began to receive their Notices in the mail on Monday. Attached are two examples of what the envelope usually looks like, depending on how you hold your shares. The word “Vote” usually appears prominently on the envelope.

The Notice contains the control numbers you need to vote your shares. If you receive more than one Notice, it means that your shares are held in more than one account. Use the control numbers provided on each Notice to ensure that all of your shares are voted.
