FUTURE CURRENT ENERGY SOLUTION FOR A CHANGING WORLD ITC ENTERGY ENTERGY ITC TRANSACTION PMO PROGRESS REPORT Q3 2012 PUBLISHED QUARTERLY BY THE PROJECT MANAGEMENT ORGANIZATION REGULATORY FILINGS UNDERWAY, PMO STEAMS AHEAD LEADER’S NOTE If you’ve ever untangled a snarled fishing line or knotted thread, you might have had a mini-experience of the work that the Transco Project Management Organization is now addressing. The PMO is hundreds of people in more than a dozen teams systematically teasing apart two businesses that are not just joined at the hip, but the ankle, knee, elbow and head. The PMO’s job is to organize thousands of miles of interconnected lines, hundreds of jobs, roles and work functions and tens of thousands of other details into two discrete, well-oiled machines. One ÒmachineÓ becomes a new part of ITC Holdings Corp.’s transmission-only company and the other remains within Entergy’s generation, distribution and customer service business. The PMO teams are making good progress. We have to be appreciative of the detailed, disciplined effort they are making every day. Now that the regulatory filing process has started, everyone in the PMO will have the additional encouragement of watching this important strategic initiative move forward in the public sphere. In September and early October, the Transco initiative was thrust into the public eye with joint local and federal regulatory filings in Louisiana, New Orleans, Arkansas, Mississippi, and at FERC. Additional filings are planned in Texas and Missouri by the end of the year. Separating two integrated businesses that have essentially grown up together is an extraordinarily complex undertaking but the PMO teams are making significant progress. In fact, all teams have completed — or nearly completed — the analysis and design phases of their work, which included comparing processes, mapping functional roles, completing an inventory of IT systems and identifying issues to resolve in spinning off and merging the Entergy transmission business. These analysis steps were necessary in order to create a blueprint for the organizational and operational requirements of ÒDay 1Ó—the date the transaction closes—and ÒDay 2Ó—the date all transitioning is complete and the organizations are fully separated and operating independently. The PMO teams are making significant progress.JOE DOMINO IMPLEMENTATION TIMELINE 2012 2013 FEB SEP. MAY MAR. NOV. JUL. MAR. APR. DEC. AUG. APR. FEB. OCT. PRE-DESIGN ANALYSIS IMPLEMENTATION DESIGNIMP.

STATUS REPORTS WORKSTREAMS PROGRESS REPORTHR/STAFFING An estimated 750 Entergy employees will join ITC and become the core of the company’s mid-South workforce. The Joint Integrated Staffing Team has defined a process to identify Entergy employees who may become employees of ITC based on their current roles and ITC’s projected needs: Group 1: Those who work in positions that are principally transmission will become employees of ITC. Group 2: Those with a mix of transmission and distribution responsibilities who will be equitably split between the companies based on needs. Group 3: Shared services employees who support the transmission business, including those in legal, human resources, accounting and other departments. The staffing process for Group 2 employees will involve decision-making based on a series of inputs including each employee’s interest, an assessment of their skills, knowledge and experiences and each company’s needs. Energy delivery and system planning and operations are developing transition plans for two milestones: first, the transition associated with the spin-off and merger and subsequently, the transition into MISO. With or without Transco, after Entergy’s operating companies move to MISO the balancing authority functions will be split between Entergy and MISO. MISO will perform many functions normally considered Òoperating the balancing authorityÓ (i.e. balancing load, generation and schedules). Entergy will perform certain local functions that MISO considers a Òlocal balancing authority;Ó these will stay with Entergy regardless of Transco. Multiple implementation teams are assessing requirements such as NERC compliance, IT systems and the effects on embedded entities within the service area. BALANCING AUTHORITY ASSET SEPARATION Asset separation teams are managing the physical separation of the business—from wires, towers and substations down to desks, chairs and laptops. Teams are assigning assets to Entergy or ITC based on usage, criticality and geographical considerations, keeping an eye on whether the resulting businesses and employees will have all the equipment and materials necessary to succeed. OTHER SUBTEAMS Nearly two dozen additional subteams are addressing functions mission-critical to the planning and implementation of the fully separated transmission business. They include Critical Infrastructure Protection, distribution operations, MISO interface, engineering, supply chain, contracts/legal support, communications and real estate/facilities, as well as nine transmission teams looking at how to split today’s organization into transmission and distribution. Each area entails detailed analysis, review, documentation and decisions. As an example, the contracts/legal support subteam has reviewed more than 400 transmission and 600 franchise agreements while developing an overall contracts approach. A LOOK AHEAD All workstreams now turn their full attention to implementation in the fourth quarter of 2012, a phase that will extend through the close of the transaction. While extraordinary progress has been achieved to date, Entergy and ITC can foresee plenty of mountains to climb. These range from navigating the regulatory approval process to managing complex information technology hand-offs. Fortunately, for people who have surmounted ice storms and hurricanes and for people who have built the nation’s largest independent transmission company, big challenges are all in a day’s work.
