DEFERRAL ELECTIONS

2.1 Elections

(a) Retainers and Fees. An Eligible Director may elect to participate in the Plan and defer Retainers and Fees by filing with the Administrator a completed and fully executed Deferral Election specifying the whole percentage of Retainers and Fees to be deferred prior to the beginning of the Plan Year during which the Eligible Director performs the services for which such Retainers and Fees are to be earned. Notwithstanding the foregoing, an individual who first becomes an Eligible Director during a Plan Year may make an initial Deferral Election for deferral of Retainers and

-3-

Fees under this Plan within thirty days after the date the individual becomes an Eligible Director, provided that such Eligible Director has not previously become eligible to participate in this or any Similar Plan. Any such election will apply to Retainers and Fees earned for services performed after the election is filed with the Administrator. Once made, a Deferral Election (including any election regarding time and form of payment) will continue to apply for subsequent Deferral Periods unless the Participant submits a new Deferral Election form during a subsequent enrollment period changing the deferral amount or revoking the existing election.

(b) Deferred Stock Units. Upon initial election to the Board, an Eligible Director will receive an award of Deferred Stock Units made under the EIX Equity Compensation Plan or 2007 Performance Incentive Plan and credited to this Plan. An Eligible Director may elect to receive Deferred Stock Units rather than shares of Common Stock upon board re-election by filing with the Administrator a Deferral Election prior to the beginning of the Plan Year in which re-election occurs. Once made, a Deferral Election will continue to apply for subsequent Deferral Periods unless the Participant submits a new Deferral Election form during a subsequent enrollment period changing the deferral percentage or revoking the existing election.

(c) Dividend Equivalents. Dividend Equivalents associated with stock options granted to Participants are credited under the Plan and subject to the payment election provisions of Article 4.

Amounts deferred under this Article 2 and any earnings thereon will be 100% vested at all times.

(b) Deferred Stock Units. The Administrator will credit Deferred Stock Units to the Participant’s Deferral Account as of the effective date of any award of Deferred Stock Units under the EIX Equity Compensation Plan or 2007 Performance Incentive Plan.

As part of a Deferral Election, a Participant may make a Primary Payment Election specifying the payment schedule for each subaccount that will be created as a result of the Deferral Election. The choices available for a Primary Payment Election (except for Participants who commenced payment of Plan benefits in 2007 or earlier) are as follows:

(a) Monthly installments following Retirement for 60 to 180 months commencing upon (i) the first day of a specified month and year that may be no later than the month and year in which the Participant attains age 75 (if the Participant has not had a Separation from Service by such specified date, payments will commence upon the Participant’s Retirement); (ii) the Participant’s Retirement; or (iii) the first day of the month that is a specified number of months following the Participant’s Retirement; except that accounts payable in EIX stock may only be paid as annual installments for 5 to 15 years; or

(b) A single lump sum payable upon (i) the first day of a specified month and year that may be no later than the month and year in which the Participant attains age 75 (if the Participant has not had a Separation from Service by such specified date, payment will be made upon the Participant’s Retirement); (ii) the Participant’s Retirement; or (iii) the first day of the month that is a specified number of months following the Participant’s Retirement; or

(c) Two to ten annual or semi-annual (twice yearly) installments commencing upon (i) the first day of a specified month and year that may be no later than the month and year in which the Participant attains age 75 (if the Participant has not had a Separation from Service by such specified date, payments will commence upon the Participant’s

Retirement); (ii) the Participant’s Retirement; or (iii) the first day of the month that is a specified number of months following the Participant’s Retirement; or

(d) Any combination of the preceding three choices.

Lump sum payments or initial installment payments will be made within 30 days of the scheduled dates (or within 30 days following the date that is six months after the Participant’s Separation from Service (or, if earlier, 30 days after the Participant’s death) if such delay is required pursuant to Section 4.5), and interest will be added to the payment amount for the days elapsed between the scheduled payment date and the actual date of payment.

If paid in installments of cash, the installments will be paid in amounts that will amortize the Deferral Account or subaccount balance with interest credited at the Crediting Rate over the period of time benefits are to be paid. For purposes of calculating installments, the Deferral Account or subaccount will be valued as of December 31 each year, and the subsequent installments will be adjusted for the next calendar year according to procedures established by the Administrator. Notwithstanding anything herein to the contrary, distribution in installments shall be treated as a single payment as of the date of the initial installment for purposes of Section 409A of the Code.
