InfoSpace Signs Mobile Gaming Agreement with Activision

LOS ANGELES, Calif., Sept. 12, 2006 - InfoSpace, Inc. (NASDAQ: INSP), a leader in mobile media, today announced that it has signed an agreement to create mobile versions of several top Activision games, including the two most recent titles from the legendary action sports superstar Tony Hawk.

InfoSpace's mobile versions of "Tony Hawk's Project 8" and "Tony Hawk's Downhill Jam" will offer gamers stunning graphics, exciting terrains and challenging tricks and jumps as well as many of the features of the console versions. InfoSpace will also develop mobile versions of "GUN," a Western-style action game, and a selection of Anthology Classic 2600 titles, which include classic games that were first designed for the Atari 2600.

"As mobile technology continues to evolve and with the increasing availability of 3G handsets, mobile gaming now enables more powerful and dynamic gameplay experiences.," said Stephen Davis, president, mobile & online media for InfoSpace. "We're excited to work with Activision to develop the coveted Tony Hawk brand for mobile as well as their most popular sport and adventure titles, offering fans the chance to test their skills and enjoy their favourite games while on the go."

"There's no denying the market penetration of cell phones, which makes mobile games a great way to extend our console brands," said David Anderson, senior director of business development for Activision. "InfoSpace is a leading mobile content, distribution and delivery company, and we look forward to building a successful relationship that puts some of our top titles in the hands of mobile gamers."

Mobile games to be released as a result of today's announcement include:

Completely revamped for next generation consoles, "Tony Hawk's Project 8" immerses players in the definitive skateboarding experience by using realistic graphics, enhanced physics, and extremely responsive controls that simulate the feeling of skating with every trick and bail.

"Tony Hawk's Downhill Jam" will allow players to experience the breakneck speed of downhill skateboard racing as they attempt some of the steepest terrains while performing tricks and outmanoeuvring opponents in locations around the globe -- from the streets of San Francisco to the rocky terrain of Machu Picchu.

Developed by Neversoft Entertainment, "GUN" turns virtual lonesome cowboys and one-armed bandits into Colton White, a vengeful gunslinger as he makes his way across the frontier of late 1800s America.

The Anthology Classic 2600 titles reintroduces old school gaming favourites such as "Pitfall 1 & 2," "Commando," "Freeway," "Keystone Kapers," "Seaquest," "Spider Fighter" and more. By combining these vintage games into one package, players can be a flying ace, a race car champion, a tennis star and space pioneer -- all in one afternoon.

Game availability depends on individual phone models and wireless carriers.
