First-of-its-Kind On-Line Music Delivery Service Provides New Music Distribution and Ecommerce Opportunities for Artists, Music Publishers and Music Retailers

Over 35 Million RealJukebox Consumers Can Now Discover and Automatically Receive the Digital Music They Want

SEATTLE and SAN JOSE, CA — June 29, 2000 — RealNetworks®, Inc. (Nasdaq: RNWK), and BackWeb® Technologies (Nasdaq: BWEB) today announced the launch of Real.com™ Music Delivery, a revolutionary service that offers artists, music publishers and music retailers a powerful new means to introduce and distribute their music to the more than 35 million unique registered users of RealJukebox™. By integrating BackWeb's Polite™ push technology into RealJukebox, Real.com Music Delivery provides an easy way for consumers to quickly grow their music collections based on their personal music preferences. New users can download RealJukebox or Real Entertainment Center for free at www.real.com.

Real.com Music Delivery enables consumers to select from 7 different music categories from different music genres (e.g., classical, alternative). Each week, up to 8 new CD quality songs matching consumers' music preferences will be automatically delivered and added to their RealJukebox music collection. Using integrated BackWeb Polite push technology, these downloads occur seamlessly in the background while consumers are online and not using the full capacity of their Internet connections. The service does not impact the performance of other Internet applications such as email, file downloading, streaming media or browsing. Initial featured music downloads will include content from a wide variety of artists and music publishers including Riffage.com, Dreamworks Records, Sub Pop Records, RykoDisc, NewTechMusic, Vagrant Records, Telarc and NovaMusica.

Real.com Music Delivery provides artists, music publishers and music retailers with a broad range of opportunities including paid-for music subscriptions and promotional music distribution. For artists and their music publishers, Real.com Music Delivery provides a powerful avenue to reach out to their fan base and gain valuable exposure for their music by distributing it to consumers interested in discovering new music. For music retailers, Real.com Music Delivery will enable many ecommerce opportunities including purchasing CDs, paid-for download songs, concert tickets, artist-related web links and other relevant offerings. Real.com Music Delivery will support multiple digital music formats and digital rights management (DRM) options to support a wide variety of business models, including the ability for certain music to expire after a pre-determined amount of time.

"Real.com Music Delivery provides yet another powerful vehicle for our many content partners to promote, merchandise and deliver great music programming," said Mark Hall, vice president, Media Publishing Division, RealNetworks, Inc. "And, it enables them to connect with the more than 35 million RealJukebox users who are interested in having fresh, high quality music automatically delivered directly every day."

"RealNetworks has provided an outstanding vehicle for the profitable and sustainable development of digital music distribution over the Internet," said Ken Wirt, CEO of Riffage.
