News release

State College, PA and Toronto, ON (August 9, 2006) – C-COR
Incorporated (NASDAQ: CCBL, www.c-cor.com) and Sigma Systems (www.sigma-
systems.com) today announced that they have agreed to terms whereby C-COR will
transition the product development and support for the C-COR Service Activation
Manager (SAM) and Service Provisioning Manager (SPM) to Sigma Systems.

The transaction is subject to customary closing conditions and is expected to
be completed this quarter. Upon closing of the transaction, Sigma will obtain an
exclusive interest from C-COR in the SAM and SPM products and assume all of the
service provider licensing and software maintenance contracts for these
products. C-COR will continue to wholly own its other OSS products, including
Key Distribution Center (KDC), Policy Service Manager (PSM), Network Service
Manager (NSM), Mobile Workforce Manager (MWM), and CableEdge.

C-COR and Sigma Systems have also agreed to terms whereby the companies will
co-market and co-sell integrated OSS solutions to the global cable marketplace.
This joint collaboration will leverage the synergies among their respective OSS
product lines to expedite the additional functionalities and capabilities
required to meet the evolving needs of cable operators. As a result, operators
will have access to an OSS product portfolio that combines automated order
management, service provisioning and activation, service authorization, resource
management and self-care capabilities from Sigma's Service Management Platform
with the functionalities of C-COR's complete line of bandwidth and resource
management, policy service management, automated workforce, and service
assurance solutions. C-COR and Sigma are worldwide leaders in OSS for cable with
deployments throughout North America, Europe, and Asia-Pacific and have
consistently demonstrated their industry leadership through continued
involvement with CableLabs.

“This is about putting innovative OSS solutions on a fast track,” stated
Robert Cruickshank, Vice President, OSS Market Strategy, C-COR. “For customers
of our SAM and SPM, folding the technology and support of these products under
Sigma Systems will provide them with broader flexibility and choice in service
activation and provisioning functionality. For the cable industry, applying the
combined experience and expertise of C- COR and Sigma to the OSS requirements of
future converged network architectures will speed innovation and provide the
shortest path to a fully integrated OSS solution for voice, video, and data over
wireline or wireless networks.”

“Sigma is delighted to announce this joint agreement, as it clearly cements
our position as a Worldwide Leader in Quad-Play Service Management,” said Andy
Jasuja, Chairman, CEO Sigma Systems. “As a result of this agreement, Sigma has a
total of 47 Deployments Worldwide, 20+ VoIP deployments, and 20M subscribers

co-promote OSS solutions provide our customers with a complete consolidation of
provisioning solutions,” said Tim Spencer, Sigma Systems President & COO.
“It allows our current and future customers to take advantage of Sigma's ongoing
R&D investment and the combination of two great sets of technology. Our
