SUMMARY NOTICE OF CLASS ACTION

If you held XO Holdings, Inc. (“XO”) common stock on July 25, 2008 and/or on July 11, 2011, it is very important that you read this notice. You must decide whether you want to remain a member of a class action against Carl Icahn and other defendants. Your decision may affect your legal rights including the right to share in any possible future recovery in this action.

This lawsuit affects: Class A: All persons that held XO common stock on July 25, 2008; and Class B: All persons that held XO common stock on July 11, 2011.

What is this lawsuit about? Plaintiffs brought this case on behalf of XO minority stockholders to challenge (i) XO’s July 25, 2008 $780 million private placement of XO Class B and Class C Preferred stock (the “2008 Recapitalization”); and (ii) the July 11, 2011 Merger between XO and Icahn’s affiliates (the “2011 Merger”). Plaintiffs allege that in effecting the 2008 Recapitalization and the 2011 Merger, defendant Icahn, XO’s controlling shareholder, breached his fiduciary duties to XO’s minority shareholders in order to take for his own use and benefit all of XO’s assets including XO’s net operating losses (“NOLs”). Plaintiffs allege that XO’s minority shareholders were harmed by Defendants’ unfair dealing and breach of fiduciary duties. Defendants deny all of plaintiffs’ claims and allegations.

Who represents you? The Court has appointed Abbey Spanier, LLP as Class Counsel.
