Safe Harbor Statement

This press release contains certain statements that describe 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 most recent Annual Report on Form 10-K and any

subsequent 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 proxy statement/prospectus included in the registration statement on Form S-4 that was filed by ITC with the SEC in connection with the proposed transactions): (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.
