Avaya Proprietary (Document and Conversation under NDA) Nimcat Networks Overview - Customer Views of Nimcat Networks (software embedded in OEM phone) VON Magazine 10/2005 Neat Technology, nice demos, and it works James Mahoney, CEO of Mahoney & Associates, isn’t a techie. Mahoney owns and runs a medical malpractice insurance agency in Walpole, Massachusetts …. He did the installation himself without any problems, including giving the phones the numbers he wanted. "I always had a dilemma with small-business phone systems," says Ben Fard, managing director at MoneyVest. "Most phone systems require a lot of money up front for equipment. Then they hit you again [with more upgrade costs] if you want to expand." He says with the VentureIP system, "you don't have to invest in a lot of back-room infrastructure." "If we grow, I'll just add phones," he says. Network World 3/2005 Vendors launch innovative VoIP gear

Avaya Proprietary (Document and Conversation under NDA) Marketplace Reaction to Nimcat Networks Acquisition Merrill Lynch “Incorporating such technology into Avaya’s IP phones could potentially change the economics of the company’s SMB and branch office solutions, narrowing (or perhaps eliminating) the company’s current cost disadvantage relative to competitors such as Cisco.” “Avaya's acquisition of private company Nimcat Networks for $46 million has long- run potential to significantly change the market dynamic for small and medium business Key/PBX/VOIP phone systems.” CIBC “Avaya's acquisition of a small provider of peer-to-peer (P2P) technologies lends credibility to an emerging, and potentially disruptive, communications architecture.” Gartner “The Nimcat acquisition presents Avaya as an IP telephony developer unafraid to think out of the box and strike out in new directions.” Current Analysis
