C-COR PROVIDES BUSINESS UPDATE

State College, PA (October 12, 2004) – C-COR Incorporated (Nasdaq: CCBL), a global provider of broadband communications transport products, software systems, and technical services, will be discussing business conditions for the first quarter of fiscal year 2005 at the Company’s Annual Shareholder Meeting today, October 12, 2004.

C-COR anticipates that net sales for the first quarter of fiscal year 2005, ended September 24, 2004, will be approximately $62 million. The change from C-COR’s previous guidance of net sales of between $64 and $67 million, provided in the Company’s news release of August 19, 2004, is due to delays in software sales during the first quarter of fiscal year 2005. C-COR anticipates that GAAP earnings, excluding an anticipated charge for in-process research and development (IPR&D), will be at the low end of the previous guidance of between $.02 and $.05 per diluted share. The projection of GAAP earnings includes $1 million related to amortization of intangible assets, or $.02 per diluted share, which is typically excluded from the First Call analysts’ projections. C-COR is breaking out these numbers to improve comparability of the projected GAAP results and the non-GAAP First Call numbers.

The Company’s earnings projection for the first quarter of fiscal year 2005 does not include an anticipated charge against earnings for IPR&D related to the Stargus and Optinel acquisitions, which closed in the first quarter of fiscal year 2005, because the Company cannot reliably estimate this charge at this time. The amount of the IPR&D charges, which is being determined by a third party appraisal, has not been finalized at this time, but is expected to be included in the Company’s first quarter results.

Detailed information on fiscal year 2005 first quarter results will be provided under a separate news release, to be dated October 21, 2004. The Company will also hold its quarterly conference call at 9:45 AM (ET) on that date. For information on accessing the call, refer to the Company’s news release, dated October 7, 2004, posted on its web site, www.c-cor.net.
