Capistrano Transaction Overview

Economics (2)

Projects sold by EME to CWP at Fair Market Value

Investors’ funding portion set by formula

Tax sharing agreement directly between MEHC and Capo Wind (Holdco of CWP)

Capo Wind allocates 99% of tax attributes to MEHC and agrees to contribute 90% of cash tax payments received from EIX to Capistrano with remaining 10% indirectly paid to EME

CWP uses project cash flows and tax sharing contributions to make distributions to partners

Investors get priority distributions until flip date

Thereafter, 55% to Edison and 45% to Investors

CWP and/or Projects also pay EME additional fees for management

Roles

EME/affiliates develop/build/operate projects and manage CWP

Investors generally passive with protective voting rights and covenants

Overview

Capistrano Wind Partners (CWP) formed February 13, 2012 by EMG, TIAA-CREF, and CIRI (an Alaskan native corporation) $460 million commitment for wind development:

Operating projects transferred – Cedro Hill, Texas (150 MW) and Mountain Wind I and II, Wyoming (141 MW) & the initial transaction netted EME ~$235 million in liquidity at completion of final projects

Additional Projects being transferred into CWP – Crofton Bluffs Nebraska (40MW) completed in Dec 2012 and Broken Bow I, Nebraska (80 MW) is expected in Jan 2013. Through these transfers EME recovers $140 million (less transaction costs) previously used to fund construction

In Dec. 2012, AMP Capital Investors (via Rest Infrastructure Trust) has been added as an additional investor

EME retains an economic interest and will continue to operate and consolidate projects

Regulatory Framework – Illinois

The Combined Pollutant Standard (―CPS‖) for air emissions is the key environmental framework for the Illinois assets

Addresses Mercury, NOx and SO2

Entered into in 2006 with the Illinois EPA and adopted as a formal state rule in 2007

CPS was crafted to anticipate potential federal regulations

Status: NOx retrofits complete on all units; Mercury control installations complete on all units utilizing Activated Carbon Injection; Construction of SO2 controls is underway at Powerton (unit 6), preliminary engineering, technical analysis underway on balance of units as needed

Strategy: Ensure CPS satisfies all Federal rules and that additional state and federal water regulations do not mandate additional, material capital expenditures

Proposed variance from CPS filed with Illinois Pollution Control Board November 30

If granted, would defer approximately $200.0 million CapEx from 2013-14 (short term liquidity improvement relative to projections)

Illinois EPA fully briefed

Public hearing January 29; environmental opposition expected; due for board order in early April

Proposed variance would extend deadline to retrofit Waukegan Unit 8 from end of 2014 to May 31, 2015, with unit offline as of December 31, 2014 until work completed

Proposed variance would provide relief from current SO2 emission rate limit in 2015 and 2016

Emission rate cap of 0.38 lbs./MMbtu in each year compared to current limits of 0.28 in 2015 and 0.195 in 2016

Proposed variance would set annual SO2 tonnage cap for 2013-16 (consistent with internal outlook) to guarantee "no environmental harm"

SO2 Control – Dry Sorbent Injection (cont’d)

A number of important considerations must be taken into account when using DSI

Particulate removal to address HAP MACT standards

Transportation, storage and milling of trona on-site

Screening of qualified vendors has focused on capital cost, life cycle cost including O&M and trona consumption associated with SO2 removal linked to grind particle sizing

Mill technology and proof of mills in this application has been a key variable in the review process

United Conveyor Corp (―UCC‖) / O’Brien & Gere selected as equipment supplier

Waukegan construction started October 2011 to preserve construction permit. Construction suspended after receipt of one year permit extension from IEPA

Powerton unit 6 construction underway, implementation is broken into two phases to maximize deferral of capital; Phase 1 up to 50% SO2 removal; Phase 2 greater than 50% SO2 removal

Phase I will be completed and operational September 2013

Phase II will be implemented at a later date as needed to meet CPS

Added ESP fields and potentially adding height to increase volume

Waukegan 8, Crawford 7&8, Fisk, and Will County 3

The ―hot to cold‖ ESP Conversion at Waukegan 7 and Will County 3 is anticipated to significantly improve existing ESP performance negating the need for baghouses

Currently don’t anticipate having to add polishing baghouses but analysis is still underway

Objective is to optimize particulate removal efficiency at the lowest overall capital cost

Sargent & Lundy and Southern Environmental (SEI) are currently engaged to complete unit level review of ESPs

Gas Production Increased production to better calibrate to actual historical production; long-run production trend

similar; long term demand reflects coal retirements (including through coal to gas switching)

Gas Demand Reflects near term weather impacts

LNG Exports Addition of 3Bcfd of exports from the U.S. Gulf Coast by 2019

Coal Prices Reduced pricing as a result of lower demand due to coal retirements and update of extraction /

transportation costs

Operating Model Assumptions

EME has developed its operating model using a combination of forward market pricing as of September 28, 2012 (through 2015) and ICF’s fundamental forecast(1) for 2016 onwards

Projections reflect actual results of RPM capacity auction through planning year 2015/2016

For illustrative purposes, financial projections and tax payments are illustrated based on publicly disclosed information in the 8-K dated 12/17/12 and do not reflect any potential changes subsequent to that date (including changes to bonus depreciation for tax year 2013)(2)

Projections assume tax sharing payments by EIX will continue though 2014 as indicated in the draft plan support agreement

Projections include the following recent and near term considerations:

1. ICF Forecast (with no National CO2 Policy) as of Q2 2012. Projections developed prior to CSAPR ruling but are not expected to change materially as a result of the new ruling

2. On 01/01/13, fiscal cliff legislation extended 50% bonus depreciation for one year (through 2013). Based on preliminary analysis, this extension is anticipated to result in a reduction in tax sharing payments to EME of approximately $400 million in 2014

In connection with the proposed restructuring, EIX has agreed to assume all EME non-executive retirement plan liabilities ($91 million), executive retirement and executive deferred compensation plan liabilities ($21 million) and certain PBOP liabilities ($51 million). The schedule below summarizes the liabilities proposed to be assumed by EIX and those anticipated to be retained by EME under the proposed restructuring

Under the proposed restructuring, EIX would assume certain unfunded pension & PBOP liabilities upon completion of the bankruptcy. EME is obligated to continue to fund such benefits during the bankruptcy proceeding. The above table provides the estimated liabilities at December 31, 2011 for reference purposes. The Assumed Liabilities at the end of the bankruptcy proceeding will differ

These liabilities, including the liabilities retained by EME, correspond to an average cash funding requirement potential savings of approximately up to $26 million per year from 2015 to 2017
