Other Events.

As previously reported, on November 17, 2007, Macrovision Corporation signed a definitive Asset Purchase Agreement (the “Agreement”) to acquire certain assets of Cryptography Research, Inc. (“CRI”) (the “Transaction”). Macrovision paid CRI $45 million in cash and may issue up to $15 million in warrants exercisable for Macrovision common stock, a portion of such warrants being subject to performance milestones, in consideration for the purchased assets. CRI is a privately-held company based in San Francisco, California. The acquisition closed on November 21, 2007. The foregoing description of the Agreement and the Transaction is qualified in its entirety by reference to the Agreement, which is filed as Exhibit 10.1 to the Current Report filed on Form 8-K/A on December 18, 2007.

Under the Agreement, Macrovision may issue up to three separate warrants to CRI. The first warrant issuable under the agreement will be exercisable for 928,315 shares of Macrovision’s common stock at an exercise price of $35.45 per share. The second and third warrants are subject to performance milestones, and would be exercisable for 530,466 shares of common stock at an exercise price of $35.45 per share and 507,540 shares of common stock at an exercise price of $34.14 per share, respectively. The warrants were committed to be issued in reliance on Section 4(2) of the Securities Act of 1933, as amended.

Under the terms of the Agreement, the first warrant was to be issued on January 1, 2008. At CRI’s request, Macrovision did not issue the first warrant on January 1, 2008. This warrant may be issued at a later date once CRI requests that it be issued.
