Entergy Forward-Looking Information In this communication, and from time to time, Entergy makes certain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Except to the extent required by the federal securities laws, Entergy undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise. Forward-looking statements involve a number of risks and uncertainties. There are factors that could cause actual results to differ materially from those expressed or implied in the forward-looking statements, including (i) those factors discussed in Entergy’s Annual Report on Form 10-K for the year ended December 31, 2011, its Quarterly Reports on Form 10-Q for the quarters ended March 31, 2012, June 30, 2012 and September 30, 2012, and other filings made by Entergy with the Securities and Exchange Commission (the “SEC”); (ii) the following transactional factors (in addition to others described elsewhere in this communication, in the preliminary proxy statement/prospectus included in the registration statement on Form S-4 that ITC filed with the SEC on September 25, 2012 in connection with the proposed transactions, and in subsequent securities filings) involving risks inherent in the contemplated transaction, including: (1) failure to obtain ITC shareholder approval, (2) failure of Entergy and its shareholders to recognize the expected benefits of the transaction, (3) failure to obtain regulatory approvals necessary to consummate the transaction or to obtain regulatory approvals on favorable terms, (4) the ability of Entergy, Mid South TransCo LLC (TransCo) and ITC to obtain the required financings, (5) delays in consummating the transaction or the failure to consummate the transaction, (6) exceeding the expected costs of the transaction, and (7) the failure to receive an IRS ruling approving the tax-free status of the transaction; (iii) legislative and regulatory actions; and (iv) conditions of the capital markets during the periods covered by the forward-looking statements. The transaction is subject to certain conditions precedent, including regulatory approvals, approval of ITC’s shareholders and the availability of financing. Entergy cannot provide any assurance that the transaction or any of the proposed transactions related thereto will be completed, nor can it give assurances as to the terms on which such transactions will be consummated.

This document and the exhibits hereto contain certain statements that describe ITC Holdings Corp. (“ITC”) management’s beliefs concerning future business conditions and prospects, growth opportunities and the outlook for ITC’s business, including ITC’s business and the electric transmission industry based upon information currently available. Such statements are “forward-looking” statements within the meaning of the Private Securities Litigation Reform Act of 1995. Wherever possible, ITC has identified these forward-looking statements by words such as “anticipates”, “believes”, “intends”, “estimates”, “expects”, “projects” and similar phrases. These forward-looking statements are based upon assumptions ITC management believes are reasonable. Such forward-looking statements are subject to risks and uncertainties which could cause ITC’s actual results, performance and achievements to differ materially from those expressed in, or implied by, these statements, including, among other things, (a) the risks and uncertainties disclosed in ITC’s annual report on Form 10-K and ITC’s quarterly reports on Form 10-Q filed with the Securities and Exchange Commission (the “SEC”) from time to time and (b) the following transactional factors (in addition to others described elsewhere in this document, in the preliminary proxy statement/prospectus included in the registration statement on Form S-4 that ITC filed with the SEC on September 25, 2012 in connection with the proposed transactions, and in subsequent filings with the SEC): (i) risks inherent in the contemplated transaction, including: (A) failure to obtain approval by the Company’s shareholders; (B) failure to obtain regulatory approvals necessary to consummate the transaction or to obtain regulatory approvals on favorable terms; (C) the ability to obtain the required financings; (D) delays in consummating the transaction or the failure to consummate the transactions; and (E) exceeding the expected costs of the transactions; (ii) legislative and regulatory actions, and (iii) conditions of the capital markets during the periods covered by the forward-looking statements. Because ITC’s forward-looking statements are based on estimates and assumptions that are subject to significant business, economic and competitive uncertainties, many of which are beyond ITC’s control or are subject to change, actual results could be materially different and any or all of ITC’s forward-looking statements may turn out to be wrong. They speak only as of the date made and can be affected by assumptions ITC might make or by known or unknown risks and uncertainties. Many factors mentioned in this document and the exhibits hereto and in ITC’s annual and quarterly reports will be important in determining future results. Consequently, ITC cannot assure you that ITC’s expectations or forecasts expressed in such forward-looking statements will be achieved. Actual future results may vary materially. Except as required by law, ITC undertakes no obligation to publicly update any of ITC’s forward-looking or other statements, whether as a result of new information, future events, or otherwise. The transaction is subject to certain conditions precedent, including regulatory approvals, approval of ITC’s shareholders and the availability of financing. ITC cannot provide any assurance that the proposed transactions related thereto will be completed, nor can it give assurances as to the terms on which such transactions will be consummated.

U.S. Transmission Grid – Historically Fragmented and Inefficient Historically, transmission infrastructure development in the U.S. primarily focused on connecting load and resources within balancing authority areas, with little interregional or national perspective Europe, Australia, etc established independent transmission ownership and operation as the cornerstone of market reform In contrast, U.S. Electric Power Transmission Grid More than 211,000 high voltage transmission line miles Operated by ~130 balancing authority areas (ownership is even more fragmented) Source: FEMA, NERC kV 115 138 161 230 345 500

“you may well expect to see an ultimate industry structure whereby the electric grid is separated, heavily regulated, treated as a natural monopoly” --J. Wayne Leonard, presentation to DOE (1996) _ “Mr. Leonard also said he wants to sell [Entergy’s] transmission system if it could be folded into a ‘transmission company,’ one genre of a company that is being considered in a restructured electric industry.” --The Wall Street Journal (1998) “A transmission organization that’s incentivized to maximize access will promote competitive markets and create the greatest value for consumers of electric power.” --J. Wayne Leonard, World Energy (1999) “Since 1998, Entergy has supported and pursued the establishment of an independent entity to operate the Entergy transmission system.” --J. Wayne Leonard, Letter to FERC Commissioners (2004)

Change in How Wholesale Rates are Determined Due to Adoption of MISO's 12 CP Demand Methodology A B Note: Amount paid remains the same because the customer consumes the same amount of transmission service in both methodologies. The methodology affects the units of measuring rates and the units of measuring consumption but the amount paid is same and is reflective of services consumed In both methodologies aggregate amount paid by customer consuming a certain amount of Transmission service will remain the same

Wholesale Rate Effects Reduced for EAI Customers Post Transition to MISO 2.5 2.0 1.5 1.0 0.5 0.0 Estimated 2014 WS rates post transition to MISO with 4 Transmission Pricing Zones 2.41 Estimated Net Rate Effect of adopting default MISO ROE and implementing 4 Transmission Pricing Zones (0.02) Estimated 2014 WS rates paid under ETR OATT under One Transmission Pricing Zone 2.43 Estimated 2014 Wholesale Transmission Rate Effects ***using 12 CP methodology*** ($/kWm) Note: Calculation indicative and illustrative is not meant to project an actual future customer bill. Estimates are preliminary and draft prior to rate filings in first quarter of 2013 Wholesale rate effects estimation does not factor in any production costs savings and other benefits to be achieved through transition to MISO RTO Illustrative Rates have been estimated using 12 CP methodology used under MISO Attachment O. Current ETR OATT methodology uses a single annual peak rather than 12 CP. Change in methodology does not imply a change in Revenue Requirements hence customers do not pay different amounts under 12 CP employed by MISO vs. single annual peak employed by ETR. The equivalent number to $2.43 /kWm under 12 CP would be a $1.85 /kWm under single annual peak. The per unit estimation may be different but the amount paid by the customer is the same.

Transaction Rationale: In the Public Interest Independent model Proven independent business model for owning and operating transmission systems Independence from all buyers and sellers of electric energy allows ITC to plan improvements to the electric transmission grid for the broadest public benefit Singular focus Transaction results in two companies that are more specialized and focused — ITC on transmission and Entergy on generation and distribution Operational excellence, cost efficiency, customer focus Wholesale markets and a regional planning view Transaction facilitates infrastructure investment and fosters competition – activities that enhance wholesale electricity markets Structural separation of the transmission business from generation and distribution businesses encourages greater participation in the transmission planning process and disclosure of information by third parties Independent model aligns with national policy objectives Financial strength and flexibility Transaction will yield separate companies with strong balance sheets and greater capability to finance the infrastructure investment requirements today and in the future

Independent Model Benefits of ITC Independent Transmission Model Transparency Improved Reliability Enhanced Generator Interconnections Aligned with Public Policy Operational Excellence Improved Credit Quality Competitive Markets Reduced System Congestion Reliability Transparency Operational Excellence Infrastructure Investment High Credit Quality Public Policy Alignment Facilitate Generator Interconnection Customer Focus

Data from the SGS Study benchmarking study can be used to quantify the resulting improved reliability The U.S. Department of Energy’s Office of Electricity Delivery and Energy Reliability has developed a tool to estimate interruption costs and the benefits associated with reliability improvements A one minute improvement in System Average Interruption Duration Index (SAIDI) for ITCTransmission and METC results in one year savings of $7.7M Compared to the performance of the median utility in the SGS Study, this amounts to a value of about $153 million per year delivered by ITC’s Michigan utilities Operational Excellence: Quantitative Value of Reliability The calculation is based on data for the two largest load serving entities in Michigan from 2010 and 2011, with major storms excluded. The ITCT and METC data reflect a three year average SAIDI from the SGS Study, given that performance changes year over year.

Utilize standard equipment when possible to drive greater efficiencies (e.g. breaker replacement completed in two versus six weeks) Utilize equipment with track record of longer life, resulting in lower maintenance and replacement costs Engage in strategic alliances to ensure that needed equipment is available to meet project timelines Purchasing power leads to better pricing when buying large volume of transmission equipment Cost Efficiencies Standardization and Specialization Ability to attract and retain personnel with high levels of interest and expertise in electric transmission avoids turnover and training costs (important when facing near-term shortage of skilled workers)

Customer Focus Dedicated Stakeholder Relations group for all stakeholders, providing advocacy and issue resolution at ITC Stakeholders include investor-owned, municipal and cooperative utilities, independent power producers and retail load of large industrial and commercial retail customers connected at transmission level voltages Proactively meet with stakeholders to identify stakeholder issues and resolve any concerns through one-on-one meetings and semi-annual “Partners in Business” meetings Energy policy, legislative and regulatory matters Capital project, transmission planning and preventive maintenance Operations preparedness for summer peak load and storm events Transmission rates Timely customer communication Storm restoration Planned outages to eliminate or minimize any potential risk and costs to industrial processes Unplanned outages regarding cause, estimated duration, and future prevention

Fosters Regional Planning ITC has track record of planning its transmission systems to: Address local, state, and regional reliability needs Increase the economic efficiency of the overall grid Respond to transmission needs identified in state and regional processes When deficiencies are identified on the transmission system, such as inadequate capacity to meet load under certain contingency conditions, ITC’s transmission planners develop transmission system reinforcements to address those deficiencies ITC is committed to planning its transmission system in an open and transparent manner. As such, ITC has its own processes that supplement the already-robust open and transparent processes used by MISO Transaction enhances customer benefits beyond what could be achieved through the Entergy Operating Companies’ proposed MISO membership ITC has proven it has the expertise, resources, and capital not only to plan but also to construct needed investment ITC’s regional approach to transmission planning will enhance deliverability of generation throughout the region to provide a more economic source of energy for customers

IPL Transaction Experience & Results ITC has invested approximately $1.1 billion to improve the ITC Midwest transmission system since acquisition of IPL assets Primarily needed to upgrade and improve existing lines and substations, construct new lines to serve load growth and improve reliability, and provide interconnection for new load and generation Major activities: Built 26 new substations Completed 32 major substation upgrades/expansions Built nearly 26 miles of new line Rebuilt nearly 400 miles of existing lines Added four and replaced three major transformers Key Project: Salem-Hazleton 81-mile, 345 kV line connecting Dubuque and Buchanan Counties in eastern Iowa Regional planning had long identified as needed to resolve system constraints and reduce energy costs. Expected completion: 2013 ITC Midwest reduced sustained outages from those experienced in 2008 (the last year IPL operated and maintained the system) by 50% in 2009, 24% in 2010, and 58% in 2011

Financial Strength and Flexibility Transaction offers the financial strength of ITC and improves that of EAI to support the escalating capital investment requirements facing the electric industry ITC has a singular focus with no internal competition or competing priorities for capital or other resources; provides a stronger, separate balance sheet to support the transmission capital requirements ITC better positioned to efficiently capitalize the significant and sustained level of transmission investment required in the Entergy region, including Arkansas Post-close, EAI would be better positioned to attract capital separately to finance needed investments in generation and distribution at lower costs and to manage future uncertainty regarding event risk (e.g., new regulatory requirements or major storms) ITC’s MISO operating companies are deemed to be of higher credit quality than EAI, as well as most vertically-integrated utilities Enables consistent and predictable access to cost-effective capital, even during challenging economic times; supports enhanced liquidity Given significant and sustained level of transmission capital investment requirements, as well as unforeseen needs, credit quality and access to capital are paramount

Credit Quality Enhancement Overview Debt Cost Savings Expect new ITC operating companies to have ratings equivalent to that of ITC’s existing MISO operating companies FERC rate construct utilized by ITC’s operating companies viewed favorably by the rating agencies and investors, which supports lower funding costs ITC is seeking FERC rate construct for its new operating companies as part of this transaction Results in lower borrowing costs of approximately 55 bps to 195 bps relative to the status quo EOCs, depending on market conditions Merger between Entergy’s Transmission Business and ITC is expected to lead to material interest expense savings, which will benefit Entergy’s customers Reflected in both the initial capitalization of the new ITC operating companies, including ITC Arkansas, as well as future debt financings to fund transmission investment requirements Aggregate debt financing cost savings estimated in the range of $24 million to $27 million in 2014 (first full year of ownership) for the new ITC operating companies Over a five-year period (2014-2018), estimate debt cost savings for the new ITC operating companies in a range of approximately $125 million to $156 million (in nominal dollars)

Comparable equity values of ITC and the Entergy Operating Companies’ combined T-business at this point in time enable execution of a Reverse Morris Trust transaction structure where T-business is spun-off to existing ETR shareholders and merged with ITC Through the Reverse Morris Trust Transaction structure, EAI will not incur a tax liability Under a taxable transaction, the tax basis of EAI’s transmission assets would be reset and Accumulated Deferred Income Taxes (“ADIT”) would be re-measured, resulting in lower balances of ADIT Because ADIT ultimately lowers T-rates in cost of service ratemaking, re-measuring ADIT would otherwise result in higher T-rates in a taxable transaction, all other things being equal As a result of the RMT transaction structure, EAI’s transmission assets will have the same tax basis post-transaction as they had prior to the Transaction Accordingly, the negative rate effects for customers that otherwise would have resulted from a change in tax basis under a taxable transaction are avoided RMT Transaction Structure Avoids Re-Measurement of ADIT Preserving Tax Basis for EAI and Protecting Customers from Negative Rate Effects of a Taxable Transaction
