ETE ANNOUNCES ELECTION DEADLINE FOR WILLIAMS STOCKHOLDERS

Election Deadline Set For 5:00 p.m., Eastern Daylight Time, on June 24, 2016

DALLAS & TULSA, Okla. – June 6, 2016 – Energy Transfer Equity, L.P. (NYSE: ETE) (“ETE”) today announced that, in connection with ETE’s pending acquisition of The Williams Companies, Inc. (NYSE: WMB) (“Williams”), the election deadline for Williams stockholders to elect the form of consideration they wish to receive in the merger, subject to proration, is 5:00 p.m., Eastern Daylight Time, on June 24, 2016.

Registered Williams stockholders are reminded that if they wish to make an election, they must complete, sign and return a Form of Election to American Stock Transfer & Trust Company, LLC (“AST”), the exchange agent for the merger, prior to the election deadline. Williams stockholders should retain the certificates representing their shares of Williams common stock and should not mail the certificates to the exchange agent at this time. Instructions on mailing certificates representing shares of Williams common stock will be provided to stockholders once the merger has closed. Williams stockholders holding shares through a broker, bank or nominee should carefully follow the instructions provided by such broker, bank or nominee to make an election. Such stockholders may be subject to an earlier deadline from their brokers, banks or nominees for making an election. Williams stockholders should carefully review all the election materials provided to them before making their election.

Williams stockholders are further reminded that during the period following 5:00 p.m., Eastern Daylight Time, on June 24, 2016 and until the consummation of the proposed merger, Williams stockholders will not be able to transfer (including by sale) shares of Williams common stock for which a properly completed Form of Election has been submitted to AST. The date on which the closing of the merger, if any, will occur is not known at this time and as a result, the period of time during which the transfer restriction will apply is also unknown. If Williams stockholders wish to retain the ability to transfer their shares of Williams common stock between the election deadline and the completion of the proposed merger, then they should not return a Form of Election. However, Williams stockholders are advised that they may still be unable to transfer all or a portion of their shares (including by sale) because, as a result of all shares of Williams common stock for which an election was validly made no longer being transferable, there may be no trading market that will provide holders with adequate liquidity to make the desired transfer.

Williams stockholders with questions regarding the election procedures, who want up to date information on the election deadline or who wish to obtain copies of the election materials may contact MacKenzie Partners, Inc., the information agent for the transaction, at (800) 322-2885 (toll) or (212) 929-5500 (collect).

The merger remains subject to a number of closing conditions, including the receipt of Williams stockholder approval and receipt by Energy Transfer Corp LP (“ETC”) and Williams of a tax opinion from Latham & Watkins LLP (“Latham”) that the contribution of Williams’ assets by ETC to ETE should qualify as an exchange to which Section 721(a) of the Internal Revenue Code applies. Latham has advised ETE that it would not be able to deliver this tax opinion were the opinion requested as of the date of the proxy statement/prospectus mailed to Williams’ stockholders. ETE believes that there is a substantial risk that the closing condition relating to this tax opinion will not be met, and that it is unlikely that ETC would waive the closing condition. Williams believes that the contribution should qualify as an exchange to which Section 721(a) of the Internal Revenue Code applies, and would be willing to waive the condition to closing that Williams receive this tax opinion. Williams has filed a lawsuit against ETE in the Delaware Court of Chancery seeking, among other remedies, a declaratory judgment and injunction preventing ETE from terminating or otherwise avoiding its obligations under the merger agreement due to any failure of Latham to deliver the 721 tax opinion to ETC and Williams. ETE has filed its affirmative defenses and counterclaim and seeks, among other things, a declaratory judgment that, in the event Latham fails to deliver the 721 tax opinion prior to the outside date of June 28, 2016 set

forth in the merger agreement, ETE will be entitled to terminate the merger agreement without liability due to the failure of a closing condition. The parties have agreed to expedited proceedings, with a trial scheduled to be held June 20 and June 21, 2016. Williams’ stockholders are encouraged to read the proxy statement/prospectus in its entirety, including the section entitled “Recent Developments,” for additional information regarding the foregoing.
