Alliance Atlantis Announces Licensing of International Second Window Rights for the CSI Franchise

TORONTO, CANADA — July 14, 2006 — Alliance Atlantis Communications Inc. today announced the licensing of certain international second window rights for the CSI franchise including CSI: Crime Scene Investigation, CSI: Miami and CSI: NY. The license fees generated for these international second window rights total approximately US$250 million.

"We have now secured second window licensing agreements in a number of countries including France, Spain, Australia and, most recently, Germany and the U.K.," said Ted Riley, Executive Managing Director of International Content Distribution for Alliance Atlantis. "These agreements with international broadcasters demonstrate the strong interest in the re-licensing of CSI around the world."

"We are exceptionally pleased with the performance of the CSI franchise in the international marketplace," said Phyllis Yaffe, Chief Executive Officer of Alliance Atlantis Communications Inc. "As we have previously stated, the franchise has outperformed our original expectations in international first window and DVD sales. With today's announcement we can confirm that the trend continues. International second window rights are worth significantly more than we had originally anticipated. We continue to have active discussions with broadcasters in other territories regarding further second window licensing opportunities."

International broadcasters that have acquired second window rights to the franchise include RTL in Germany, Five in the United Kingdom, TF1 in France, Telecinco in Spain, Nine Network in Australia and CTV in Canada. These sales include both produced and future episodes of CSI. To date, the CSI franchise has produced 287 hours of programming inventory.

Alliance Atlantis also announced video-on-demand (VOD) partnering agreements for the CSI franchise in certain European territories including Germany and the United Kingdom, to take advantage of emerging opportunities in cable and online distribution.
