FOR IMMEDIATE RELEASE

ICAHN EXTENDS TENDER OFFER FOR LIONS GATE COMMON SHARES

New York, New York, May 21, 2010

Contact: Susan Gordon (212) 702-4309

Carl C. Icahn announced today that the offer by his affiliated entities to purchase up to all of the outstanding common shares of Lions Gate Entertainment Corp. for $7.00 per share in cash has been extended and will now expire at 8:00 p.m., New York City time, on June 1, 2010, unless extended or withdrawn. All other terms and conditions of the tender offer remain unchanged.

Mr. Icahn stated: “We find reprehensible Lions Gate’s recent announcement regarding the board’s approval of the establishment of a trust that would hold approximately $16 million in cash to fund severance obligations that would purportedly be due to members of senior management should their employment be terminated without “cause” in connection with a “change in control”. We believe this latest action, together with the board’s failed and misguided attempts to implement a poison pill and its reckless retention (at enormous expense to shareholders – with no discernible benefit) of no less than six professional advisory firms (two financial advisors, three law firms and a public relations firm) to defend against our offer, shows just how far removed this board has become from its mission of holding management accountable and safeguarding the interests of shareholders. The Icahn Group reserves all rights to challenge the propriety of the establishment of this trust as well as the propriety of the purported severance obligations and to bring any and all other claims that the Icahn Group may have against the board and management.”

As of noon, New York City time, today, a total of approximately 4,660,699 common shares of Lions Gate were validly tendered and not withdrawn. The complete terms and conditions of the tender offer are set forth in the Offer to Purchase dated March 1, 2010, as amended by the Notice of Variation and Extension dated March 19, 2010, the Notice of Variation and Change in Information dated April 16, 2010, the Notice of Extension and Change in Information dated April 30, 2010, the Notice of Extension and Change in Information dated May 10, 2010 and the Notice of Extension and Change in Information dated May 21, 2010.
