Glu Mobile and PlayFirst™ Partner to Bring Diner Dash™ to Mobile Phones

SAN MATEO, Calif. - September 20, 2005 - Glu Mobile (formerly Sorrent, Inc. and Macrospace Ltd.), a leading creator and global publisher of mobile entertainment, and PlayFirst, the leading full-service publisher of downloadable popular games for the PC, today announced that Glu will publish a number of PlayFirst™ titles for mobile, including the wildly popular Diner Dash™.

"PlayFirst has emerged as a leader in the casual games market and shares Glu's goal of delivering entertaining games to a wide variety of people," said Robert Nashak, senior vice president of production, Glu Mobile. "Diner Dash combines a simple game mechanic with a gaming experience that includes character development and a fun storyline and is an example of a game with broad consumer appeal that is perfectly suited for the mobile platform."

"Expanding our publishing reach to the mobile phone has always been a keenly anticipated milestone in our roadmap," said Kenny Dinkin, vice president and executive producer, PlayFirst. "As a full-service publisher, our commitment to developers is to take their accessible, engaging games to the places where the mass market seeks digital entertainment. Because of the tricky nature of the mobile business we knew we'd need to partner with an established mobile publisher, and Glu's expertise in development and global deployment of titles made this decision easy."

Diner Dash, originally a downloadable PC and Mac game, has been the No. 1 title on major game sites like Yahoo! Games, MSN Games® and Shockwave.com™. Developed by the award-winning independent studio gameLab, Diner Dash is the first PlayFirst game that Glu will publish for mobile and will be available to consumers worldwide via their cell phone carriers in the first half of 2006.
