GREENWOOD VILLAGE, CO and BUFFALO, NY – December 7, 2004 —
Adelphia Communications and Synacor, a leading provider of technology supporting
the delivery of bundled online services, today announced that Synacor’s Portelus
technology platform will be used to power Adelphia’s new High-Speed Internet
service customer home page that was jointly developed by Adelphia and Synacor.

page, including a wide variety of news from Associated Press, streaming media
clips, and a free online photo service, among others.

Adelphia will relaunch its improved High-Speed Internet
customer home page as part of a larger campaign focusing on a commitment to
providing value-added premium services, easy access to online customer service
options, and packaging useful free online content for its High-Speed Internet
customers. The redesign is an easy-to-use, reliable and fully featured package
of services. The redesigned portal will also allow Adelphia to rapidly introduce
new value-added services.

"Our new customer home page will further improve the value of
our High-Speed Internet service and provide the foundation for us to introduce a
wide range of value-added services. Synacor’s platform and existing
relationships with third-party service providers allows us to expand and evolve
our offering easily over time," said Karl Ossentjuk, Vice President of Internet
services project management for Adelphia.

Synacor’s platform, Portelus, enables a variety of online
content on the Adelphia High-Speed Internet customer home page to be fully
integrated and available through a single user-id, password, and interface.

"The Adelphia management team understands the importance of
adding value to its High-Speed Internet offerings. We expect to bring
significant personalization to Adelphia High-Speed Internet subscribers through
our platform to support their value-added services strategy," said Ron Frankel,
President and CEO of Synacor. "Our specialized expertise, as well as our proven
ability to partner effectively to provide the best high-speed experience
available, is certain to deliver great value to Adelphia consumers."

The new customer home page will be included as part of all
