Limelight Networks is now the exclusive CDN service provider for all Musicmatch content and software downloads

PHOENIX, AZ - April 24, 2002 - LIMELIGHT NETWORKS, the leading provider of next-generation content delivery services for the Internet, today announced an expanded relationship with Musicmatch, the recognized leader in music software and subscription services. Limelight Networks is now the exclusive delivery network for all Musicmatch content, as well as the Musicmatch JukeBox application. The exclusive delivery agreement with Limelight Networks, in conjunction with Musicmatch's embedded updating mechanism provided by Marimba, will help Musicmatch extend its competitive advantage in their highly dynamic business.

Musicmatch Jukebox, with more than 25 million registered customers worldwide is the number one-selling music software at retail and online. Usage continues to grow with 1 million new users being added each month. It's the ultimate personal music system, enabling music lovers to play, rip, burn and organize all their music files in one easy-to-use program.

Musicmatch uses Marimba's Embedded Management technology to manage its award-winning Musicmatch Jukebox across Limelight Network's pervasive, highly scalable content delivery network. This combination of performance reliability and Marimba's embedded technology enables Musicmatch to improve the speed and download reliability of music and application updates to its Musicmatch Jukebox. In addition to content and application updates, Marimba technology enables Musicmatch to transparently deliver enhanced services, automatically providing all Musicmatch Jukebox customers with the latest version of the software and supporting the Web-based delivery of new personalized services that improve their music listening experiences.

Prior to this agreement, Musicmatch content was served by multiple CDN providers, while user updates via Marimba's embedded technology were handled by a third party hosting provider. "Consolidating all content and software download delivery with Limelight Networks simplifies IT operations and magnifies the cost savings Musicmatch realizes by using our EdgePrism technology," said Limelight Network's president, Bill Rinehart.

Limelight Networks serves Musicmatch content and software downloads from servers strategically located around the globe to improve response times and enhance the quality of the user experience. Equipment and IT costs are

reduced because Limelight Networks' customers do not need to buy, deploy, or maintain complex, rapidly evolving server and networking systems.

"I am a great fan of Limelight. They have delivered on all counts - reliability, performance and cost savings. We realized that by shifting all our delivery to Limelight Networks we could realize even greater savings and gain greater operating efficiency," said Bill Caid, vice president of Internet operations at MusicMatch.

Marimba's Embedded Management solution will help Musicmatch streamline delivery of detailed, personalized music recommendations to customers to help them enhance their music listening experiences. Marimba makes these services possible by allowing software companies and device manufacturers to transparently deliver and install new features, OS patches, and software fixes in the form of updates, without user intervention.

According to Marimba's vice president of embedded management, Michael Hughes, "We view Limelight Networks as a key partner that can enable us to deliver the Musicmatch application in a fast, efficient and reliable manner. We look forward to working with them in the future to deliver cost-effective, scalable distribution solutions for the next-generation of Internet-centric applications."
