all major industry standard formats. Activate's more than 300 customers include
Microsoft, EMC, Compaq, Safeco, and Adobe. Resellers include Carson Thomson,

create a stronger, unified company that addresses a rapidly growing marketplace
with audio/video webcasts, conference and presentation streaming, hosted digital
music samples and solutions, Internet radio and other advanced digital media

THE TRANSACTION

The acquisition of Activate represents an extension of Loudeye's digital media
services into the rapidly growing enterprise streaming market, strengthening
Loudeye's revenue mix and creating important strategic and synergistic value.
Jupiter Media Metrix projects the enterprise streaming market will double from
$290 million this year to $580 million in 2002, growing to $2.8 billion in 2005.

Founded in 1997, Activate generated revenues of $7.7 million in 2000. Loudeye
expects that Activate will generate revenues of between $8 million and $9
million for the full year 2001, growing to approximately $12 million in 2002.
Loudeye also anticipates that Activate's operations will turn cash flow positive
by the end of 2002.

Loudeye anticipates it will record a special charge related to the consolidation
of operations of between approximately $2 million and $2.5 million in the third
quarter, most of which will be non-cash.

SYNERGIES AND STRATEGIC VALUE ADDED

The combined entity will offer broad strategic and technological synergies
including infrastructure technologies, multimedia publishing applications,
intellectual property and patents, and complementary digital media technology
expertise. Additionally, Activate's hosting infrastructure, webcasting
technologies, ad insertion expertise and streaming content delivery networks
will enhance the scalability of Loudeye's digital media services, hosted music
samples business and Internet radio solutions.

Economies of scale are anticipated from combined bandwidth purchasing power, as
well as consolidated corporate infrastructure in areas such as finance,
administration, public relations, marketing and human resources. Approximately
85 of Activate's employees will remain with the combined entity in key roles
such as production, operations, customer service and support, sales and
marketing.

Loudeye expects many of its existing customers and strategic allies, such as
AOL, Bertelsmann, MSN, Amazon.com, EMI, Sony, Vivendi Universal and Warner
Records, will be excellent prospects for Activate services.

INTEGRATION

Activate President and Chief Operating Officer Dennis Shepard will assume the
role of president and general manager of the Activate subsidiary under Loudeye.

members of the Activate management team will remain in their current roles.

Loudeye expects to consolidate its digital media services, music samples and
Loudeye Radio business units into Activate Grand Central, Activate's
state-of-the-art digital media broadcast facility, which manages and streams
thousands of simultaneous audio and video signals.

media services and applications, delivered from a more efficient, single company
with an enhanced technology base, combined experience, and reputation for
unrivaled customer service. Activate's customers will also benefit from
Loudeye's commitment to advance Activate's technological and market leadership
position.

Commenting on the acquisition, Loudeye Chief Executive Officer John T. Baker

expertise into a lucrative market on the threshold of accelerated growth. This

for training, product marketing, sales support, corporate communications,
customer service, public relations and travel."

as our more than 300 customers will attest," said Dennis Shepard, Activate

resources will enable Activate to accelerate the deployment of new and upgraded
services, become more aggressive in our marketing activities and shorten the
path to profitability."
