Cablevision’s Rainbow Media Group Tracking Stock Begins Trading On New York Stock Exchange

Bethpage, NY – March 30, 2001 – Cablevision Systems Corporation (NYSE:CVC) announced today that its new series of Cablevision common stock, called Rainbow Media Group tracking stock, commenced trading on the New York Stock Exchange under the ticker symbol (NYSE: RMG).

The RMG tracking stock is designed to reflect the separate economic performance of certain businesses and interests of Rainbow Media Holdings, Inc. These include Rainbow’s national programming networks and selected regional programming assets: American Movie Classics, Bravo, The Independent Film Channel, WE: Women’s Entertainment (formerly Romance Classics), MuchMusic USA, Rainbow’s interest in the national service FOX Sports Net, Rainbow’s five regional sports channels outside of the New York market, and Rainbow Network Communications.

“The RMG tracking stock provides our shareholders with an excellent vehicle to recognize the asset value within Rainbow Media Group while giving Cablevision greater flexibility to pursue growth opportunities at our national networks,” said James L. Dolan, president and CEO, Cablevision Systems Corporation. “Depending on their particular investment objectives, the new equity structure now allows investors to invest in either Cablevision NY Group common stock, which focuses on our New York cable, programming and entertainment assets, or the new Rainbow Media Group tracking stock, which focuses on our national programming assets,” Mr. Dolan continued.

On February 1, 2001, Cablevision and Metro-Goldwyn-Mayer Inc. (NYSE:MGM) announced an agreement for MGM to make a cash investment of $825 million in exchange for a 20 percent stake in four of Rainbow’s national networks – AMC, Bravo, The Independent Film Channel and WE: Women’s Entertainment. Following the completion of the MGM transaction, Rainbow will continue to manage those programming networks. MGM’s 20 percent ownership interest in the four networks will not be part of the assets included in the Tracking stock. The agreement is expected to close the first week of April.
