Broadband Service Provider Markets

C-COR.net Corp. (Nasdaq:CCBL), a worldwide provider of broadband transport products, software systems, and technical services, today announced that the Company has entered into an agreement to acquire all of the assets of Alopa Networks, Inc. (www.alopa.com) for a cash payment of approximately $15 million and the assumption of certain liabilities. Alopa, a privately-held company headquartered in Sunnyvale, California, is a pioneer and leader in the design, development, and deployment of infrastructure software solutions for end-to-end activation, management, and assurance of digital services over cable. The purchase transaction is subject to customary closing conditions and is expected to be completed in the fourth quarter of C-COR's fiscal year 2004. With the completion of the purchase, Alopa will become part of C-COR's Broadband Management Solutions (BMS) division. C-COR anticipates that in fiscal year 2005 the Alopa acquisition will add approximately $7 million in net sales and contribute to earnings after integration is completed, which is expected to be within six months.

Commenting on the acquisition agreement, David Woodle, Chairman and CEO of C-COR, stated, "With a strategic focus on the digital networks of the future, we believe that the powerful combination of Alopa's subscriber management component with our own network service and mobile workforce applications will find strong acceptance among our customers and position C-COR as a global leader in OSS broadband solutions."

Thomas Engdahl, CEO of Alopa Networks, concurred, "This is a win/win for both Alopa and C-COR customers. Through this acquisition, C-COR will deliver strength, stability, and product depth to its customer base by capitalizing on Alopa's technology, products, and team of professionals."

Founded in 1999, Alopa Networks has been an industry driver in developing operations support software (OSS) solutions for broadband service providers that accelerate time-to-market for advanced network-based services and applications, including Internet telephone (VoIP), differentiated access, security, multimedia, and more. Alopa's combined family of products automates the complete life cycle of subscriber acquisition and service management by facilitating service creation, deployment, and assurance and security functions while, at the same time, accelerating revenue and lowering operating and capital expenses. Its flagship Alopa MetaServ(TM) platform is currently the only industry solution that automates the entire subscriber life cycle -- from equipment qualification through service creation and activation to customer support -- and integrates all layers of the IT infrastructure, including billing, order entry, customer care, and network management. It also provides secure provisioning for both PacketCable(TM) and CableHome(TM) networks, offering a framework for VoIP, multimedia services, and interactive gaming.

Alopa MetaServ is designed to support advanced data, voice, and video services with little or no development effort, minimizing or eliminating service support costs. Further, the platform's open architecture allows seamless integration with existing network infrastructures and IT architectures, thereby ensuring easy adaptability to emerging broadband standards. With over 35 customers worldwide across multiple markets, Alopa Networks is recognized for its leading role in key industry standards groups such as DOCSIS, PacketCable, and CableHome forums. Alopa's subscriber management component will be added to C-COR's ISM(TM) (Integrated Services Management) suite of network service management and mobile workforce management system applications for the broadband industry.

C-COR will hold a conference call regarding the agreement to acquire Alopa on Tuesday, May 11, 2004, at 11:00 AM (ET).
