ABOUT INTERLINK NETWORKS

THE COMPANY

Interlink Networks is a leader in securing access to public and private networks. Our
products manage user access to dial-in, broadband, mobile, and wireless LAN
networks. Interlink Networks’ RADIUS-based access control software provides the
authentication, authorization, and accounting infrastructure that enables secure and
reliable network access for thousands of enterprise and service provider networks
worldwide.

Interlink Networks is headquartered in Ann Arbor, Michigan. We have a worldwide
network of resellers and distributors.

OUR MISSION

Interlink Networks’ mission is to be a worldwide leader in providing solutions for
securing access to public and private networks. By securing access to the network,
we provide network operators the first line of defense against unauthorized access to
an organization's computing resources.

OUR HISTORY

In July 2000, Interlink Networks was formed by a spin out of technology and
developers from Merit Network, Inc., a world-renowned designer, developer, and
implementer of Internet technology, hosted at the University of Michigan.
The founders of Interlink Networks spent over a decade defining and developing the
world's best carrier-class RADIUS (Remote Access Dial-In User Services) server.
Mr. John Vollbrecht, Interlink Networks' Founder and CTO, issued the first RFP for
centralized AAA ten years ago, and championed the resulting RADIUS standards
through the IETF Standards Groups. Mr. Vollbrecht’s name is on many of the RFCs
that define RADIUS and AAA.

The charter of Interlink Networks is to expand upon its vision of providing the most
advanced authentication products, and to expand its solution set beyond remote
access into other network access mechanisms that require authentication and
authorization. As networks become more complex, and the means to access
networks expands, Interlink will continue to assure that the “interlinks” between
users and their networks are protected and secure.
