Introduction
------------

C-COR.net Corp. (the "Corporation) designs, manufactures and markets network
transmission products and provides services and support to information service
providers.  The Corporation's principal customers are cable television system
operators who operate hybrid fiber coax ("HFC) networks for delivering video,
voice and data services. The Corporation's principal products are network
transmission equipment, including radio frequency ("RF") amplifiers and AM fiber
optic systems and nodes.  The Corporation's services include network design,
activation, optimization, management and maintenance.   The cable television
industry is undergoing both significant growth and change as a result of the
deregulation of the communications industry and demand by consumers for more and
better information services.  The Corporation's strategy is to provide complete
network solutions to enable the Corporation's customers to meet the growing
demand for interactive broadband communication services, including high-speed
Internet access, telephony, and video-on-demand.

In fiscal years 1999 and 1998, the Corporation operated in one industry segment
broadly defined as the Electronics Distribution Products segment, which
represents the Corporation's continuing operations.  In order to expand the
Corporation's product offering in the Electronics Distribution Products segment,
on September 17, 1999, the Corporation consummated a merger with SVCI, a
California corporation, whereby SVCI became a wholly-owned subsidiary of the
Corporation.  This acquisition will enable the Corporation to broaden and
strengthen its network distribution product offering by adding advanced fiber
optic products to its existing RF and fiber optic equipment.

In addition, on July 9, 1999, the Corporation consummated a merger with
Convergence, whereby Convergence became a wholly-owned subsidiary of the
Corporation.  The merger with Convergence will enable the Company to offer an
integrated package of network management and support services and products.  As
a result of this merger with Convergence, in the next fiscal year, the
Corporation will operate in a second business segment called Broadband
Management Services, which will provide Internet enabling technical services and
support to broadband network operators in the United States.

In fiscal year 1997, the Corporation operated in two industry segments: the
Electronics Distribution Products segment and the Digital Fiber Optics
Transmission Products segment, which has been

                                       2
<PAGE>

reported as a discontinued business segment. The Digital Fiber Optics
Transmission Products segment provided products for long-distance, point-to-
point video, voice and data signal transmission applications, primarily for
telephony, distance learning and other non-cable television markets. On July 10,
1997, the Corporation announced the discontinuance of its Digital Fiber Optics
Products segment in a nine-month wind-down process. See "Discontinued
Operations". In the remainder of this document, the discussions are based on the
Corporation's continuing operations, the Electronics Distribution Products
segment and Broadband Management Services segment, except where the context
indicates otherwise.

The Corporation's headquarters are in State College, Pennsylvania, and its
manufacturing facilities are in State College and Tipton, Pennsylvania, Santa
Clara, California, and Tijuana, Mexico.  The Corporation operates a Network
Operations Center in Suwanee, Georgia, and administrative offices in Toronto,
Canada and Almere, The Netherlands.  The Corporation also maintains 9 regional
sales offices throughout the United States and Asia.

Industry Overview
-----------------

Cable television system networks consist of a headend to receive television
signals, a transmission network to distribute the signal throughout the network
and connections from the transmission network to the subscribers.  Historically,
these systems offered one-way only video service.  Recently, the cable
television industry, like other parts of the communications industry, has been
undergoing substantial change as a result of:

 .  Deregulation that allows competition among communications companies,
   including wireline and wireless telephone companies and cable operators, for
   communications services;

 .  Demand by consumers for two-way, high-speed broadband communications to
   accommodate Internet, telephony and other new information services; and

 .  Multiple technologies that attempt to address the need for high-speed local
   loop connections, such as dense wave division multiplexing (DWDM), digital
   subscriber lines (DSL) and local multipoint distribution service (LMDS).


For the cable television industry, these factors are resulting in:

 .  Upgrading existing cable networks to two-way, interactive broadband networks
   to provide new services and to compete against other communications
   technologies including DSL, LMDS and direct broadcast satellite (DBS);

 .  Greater utilization of fiber optic technology, including DWDM into the
   network;

 .  Consolidation among cable operators, driven by the increased capital needs
   of the system upgrades;

 .  Investments in cable operators by non-cable operators in an effort to compete
   for both new and existing services and to provide a full range of
   communication services; and

 .  Increased demand for more reliable cable networks resulting from the new
   services being offered.

Strategy Overview
-----------------

The Corporation's comprehensive product line allows it to offer end-to-end
equipment for the three HFC network segments. The Corporation's Broadband
Management Services business segment provides its customers with a wide array of
services such as network design, activation and performance management, which
work in conjunction with its equipment product line as well as other product
lines.

The Corporation has been providing HFC distribution products and services and
customer support to cable operators for over 45 years.  The Corporation's
customers include the largest cable multiple

                                       3
<PAGE>


systems operators in the United States, many of the smaller domestic cable
operators, and several large cable operators internationally. As the
Corporation's customers upgrade their HFC networks to accommodate the Internet,
telephony and advanced digital services, its core business strategy is to
leverage its over 45 year legacy for quality and service, its strong customer
relationships and its extensive installed base of transmission equipment to
provide a full line of flexible, reliable and cost-effective network solutions.
The Corporation is seeking to implement this strategy through both internal
development of new products and services as well as acquisitions. Specific
aspects of the Corporation's strategy include:

Provide Comprehensive HFC Network Product Line.  The Corporation's principal
product has been RF amplifiers which increase the power of an RF signal so that
it can be transmitted further in the network and used from "the headend to the
curb."  The Corporation has undertaken initiatives to broaden its product line
to capture the additional investment being made by cable  operators.  First, in
December 1998, the Corporation introduced its NAVICOR family of optical node
products.  Second, in July 1999, the Corporation acquired Convergence.com, which
allows the Corporation to resell headend and network equipment such as servers,
routers and cable modem termination systems that are required to transmit high-
speed data across cable networks.  Third, in September, 1999, the Corporation
acquired Silicon Valley Communications, which added advanced fiber optic headend
equipment and optical transmitters and receivers.  The Corporation has delivered
these new products to enable next generation, fiber-rich, two-way HFC
architectures such as that being deployed in field trials by AT&T.

Leverage Extensive Installed Base of Equipment for Upgrade and Rebuild Sales.
The Corporation intends to leverage its large installed base of transmission
equipment in its customers' networks through upgrades, rebuilds and node size
reductions.  Over the past four years the Corporation has shipped approximately
1 million RF amplifiers.  The Corporation provides a more cost effective upgrade
path for its customers due to its ability to upgrade existing components for its
installed products base rather than requiring all new equipment.  As the
Corporation's customers continue to upgrade their networks, the Corporation
believes that this path will provide it with a competitive advantage in
providing this equipment.

Provide Next Generation Network Management Services to Enhance Network
Integrity.  The requirement for HFC network integrity and reliability has become
much greater as traffic and complexity increased and as networks become
increasingly used for critical communications such as telephony and electronic
commerce.  However, current approaches to managing HFC networks focus on
monitoring limited, individual elements of the network such as the cable modem
or power supplies.  Through the Corporation's network management software and
Network Operations Center, the Corporation can provide a comprehensive,
proactive view of the network from the set top box and/or modem to the headend.
The Corporation intends to continue developing its network management services
to address the various types of equipment and the unique characteristics of the
different information types that will be delivered over future HFC networks.

Deliver Total Network Solutions to Meet Cable Operators' Emerging Broadband
Needs.  The Corporation believes that it is able to offer a broad network
solution to cable operators by delivering a comprehensive line of equipment and
the network services that these cable operators need to offer additional and
improved services to their subscribers.  The Corporation is able to design the
network to enhance reliability, deliver the equipment and software, furnish
installation and activation services, and provide ongoing network management and
support services.

Increase International Sales.  The Corporation is currently supplying products
and services to a number of large international customers, including cable
operators in Canada, Europe, Asia and Latin America.  The Corporation intends to
invest in further developing its international distribution channels and in
providing localized versions of our products.  With its broadened product and
service offering, the Corporation intends to supply comprehensive network
solutions to these and other operators in various international markets who
generally prefer to purchase products and services from suppliers offering a
more complete product line.

HFC Products

An HFC network connects a central information source, typically referred to as
the headend, to individual residential users through a physical plant of fiber
optic and coaxial cables and a variety of electrical and fiber optic devices
that transmit, receive, modulate, and amplify the signals as they move through
the network.  A typical HFC network consists of three major segments: the
headend, the node and the RF plant.  The Corporation offers a full range of
products for each of these segments.

Headend Equipment

The headend receives information from a satellite transmission, gateway to the
Internet or telephony network or other source and converts this information to
laser modulated optical signals for transmission across the network.  Larger
networks feature both primary headends and a series of secondary headends or
hubs.  The Corporation offers a broad range of headend equipment that features
advanced technology.

Nodes

The general function of the node in the HFC network architecture is to convert
information from optical signals to RF signals to prepare the information for
distribution to the home.  The Corporation offers a family of node products
under the NAVICOR brand name that are upgradeable, scalable, modular and fully
integrated with our RF amplifiers.  This allows RF amplifiers to be upgraded to
become nodes and simple nodes to be upgraded to become telecommunication nodes
with narrowcasting and redundant configurations.  Narrowcasting refers to
tailoring content for certain subscribers by dedicating wavelengths to that
content.  The optical components of the nodes are designed to fit into the lid
or cover of the housing so that upgrades from amplifiers to nodes are easily
accomplished by replacing the lid.

Recently, the Corporation introduced a new family of fiber optic nodes, the
MuxNode and the MiniNode, that are used in architectures designed for node sizes
of 50 to 100 homes

RF Plant

The RF plant is comprised of the products that transmit information between the
nodes and the residential users.  These products are essentially RF amplifiers
that come in various configurations such as trunks, bridgers, and line
extenders.  A trunk is used to handle a large amount of information in a network
in which the node is further from the home. A bridger splits the signal to send
it to a greater number of destinations.  Line extenders move the information to
the home.

The following table summarizes the Corporation's major products and their
primary functions and features:

New HFC Products

MuxNode and MiniNode.  The Corporation has introduced two new fiber optic
products, which have recently begun field trials with AT&T's LightWire(TM)
Neighborhood Broadband System in Salt Lake City, Utah.  The Corporation believes
these two products, the MuxNode and the MiniNode, are key components of the next
generation of HFC architecture.  This architecture provides for the broader
deployment of fiber into the network, thereby providing increased bandwidth and
greater network reliability.  The MuxNode is an advanced, scalable, bi-
directional fiber optic network device.  The MuxNode is used to transmit and
receive fiber optic signals to up to twelve MiniNodes.  The MiniNode is a high
output receiver, which replaces many of the amplifiers in the network and is
designed to serve approximately 50 to 100 homes.  The MiniNodes feature multiple
forward and reverse paths that support analog video, digital video, high-speed
data and telephone applications.  This new architecture is designed to
facilitate high-speed, interactive broadband communications that allow
operators to provide new and enhanced services to customers with greater network
reliability.

The MuxNode and MiniNode feature DWDM technology which allows multiple signal
wavelengths to be transmitted at the same item across the network.  This
increases the volume of information that can be conveyed over the network.  It
also allows cable operators flexibility in tailoring content for individual
subscribers by dedicating certain wavelengths to that content, for example,
video-on-demand.

Broadband Management Services

The Corporation also offers a broad array of services to assist its customers in
operating reliable networks with high integrity.  These services include design,
activation, network management and optimization, and ongoing support, repair and
maintenance.

                                       6

Network Design.  Network design involves providing a customized plan for high-
reliability and cost-effective HFC network upgrades and rebuilds.  The
customized plan takes into account the current state of the network and the
target applications including such factors as channel capacity, two-way
requirements, performance specifications, powering needs, high-speed data
transmission, Internet access and network management options.  The plan details
the quantity, type and configuration of equipment required in the headend as
well as throughout the remainder of the network.  Deliverables include design
services, highly accurate maps, bill-of-materials and custom drafting.

Activation Services.  Activation services are required for a newly installed or
upgraded network to become operational.  They include activation/energizing,
sweep and balance and proof of performance testing.  The purpose of these
services is to identify and correct any problems that may exist within the newly
configured system and to validate that the construction is sound and the system
is operating optimally.

Network Management Software.  The Corporation's network management software
offering, CNM System 2, is a third generation product that automatically
identifies new units in the network and receives signals from intelligent agents
that provide early notice of equipment and other network related problems.  CNM
System 2 is based on industry standards, which facilitate use with numerous
network elements and maximize interoperability with other software applications.
The Corporation's NAVICOR and I-Flex product lines are fully integrated with CNM
System 2.

The Corporation has implemented additional network management software in its
Network Operations Center in Suwanee, Georgia. This software facilitates
proactive monitoring and management of networks by identifying usage trends,
pinpointing customers that consume large amounts of bandwidth for special
billing, and providing real-time fault detection and provisioning advice.  The
Center's software collects data and other information from cable modems
installed in the home thereby increasing the amount and reliability of data
available to proactively manage the network.  The Corporation is currently
working to integrate its CNM System 2 software with the Network Operations
Center software to provide a more comprehensive network management product both
for use in its Network Operations Center and for licensing to customers.

Network Management Services.  Through its Network Operations Center, the
Corporation is currently providing a number of network management services to
smaller cable operators.  These services include server management,  RF
technician help-desk support and end-user help-desk support as well as the basic
monitoring of the overall network integrity.  Server management monitors the
servers and routers installed in the customer headend that control the flow of
high-speed data traffic.  This service includes remote backups, problem
diagnosis and secondary service. RF technician help-desk support uses the cable
modems as telemetry devices and aids the operator in troubleshooting, problem
diagnosis and maintenance of the RF cable plant.  End-user help-desk services
take inbound calls from cable company subscribers with problems and questions on
Internet service and browser network applications.

Network Operations Center Consulting and System Integration Services.  The
Corporation provides program management, engineering and technical resources to
cable operators to assist them in the design, development, implementation and
operation of their own network operations centers.  Typical deliverables during
the planning and design phase include the site survey, business process
assessment, services architecture planning, customer capability assessment,
concept of operations document, systems architecture documentation and detailed
bill-of-materials. The Corporation will also procure and install all equipment
and software, including third party as well as the Corporation's equipment and
software.  The Corporation offers customized software development to integrate
the network management software with other customer applications such as
billing, dispatching and geographic information systems.

Equipment Services Center.  The Corporation's Equipment Service Center provides
repair and maintenance services on transmission equipment from all
manufacturers.  Repair services include documentation of parts, labor and
problem identification.  Upgrade services include such activities as bandwidth
increases and frequency changes.

During the past fiscal year, the Corporation's cable television customers have
included almost all of the largest system operators in the United States. The
Corporation's largest customers during the fiscal year ended June 25, 1999, were
Time Warner and AT&T accounting for 28% and 17%, respectively, of net sales. The
Corporation's largest customer during the fiscal year ended June 26, 1998, was
Time Warner Cable, which accounted for 31% of net sales.  The Corporation's
largest customer during the fiscal year ended June 27, 1997, was Time Warner
Cable, which accounted for 36% of net sales. No other customers accounted for
10% or more of net sales during fiscal years 1997, 1998 and 1999, respectively.

Sales and Distribution
----------------------

Sales efforts are conducted from the Corporation's headquarters; from offices in
Europe; from 10 regional sales offices located throughout the United States,
Canada and Asia; and through numerous distributors around the world.

The Corporation sells its products and services in the United States through its
direct sales force, which is geographically organized.  The Corporation
approaches its customers at both the corporate level and in their individual
cable systems.  A highly qualified technical staff supports the Corporation's
sales force. They work closely with customers to design systems, develop
technical proposals and assist with installation and post-sale support.
International sales in Canada, Europe, Asia and Latin America are made through
the Corporation's direct sales force and through distributors.

Additionally, the Corporation provides 24 hours per day, 7 days per week,
technical support, both directly and through distributors, as well as training
for customers and distributors, as required, both in the Corporation's
facilities and on-site.

The Corporation's marketing organization develops strategies for product lines
and, in conjunction with the sales force, identifies evolving technical and
application needs of customers so that product development resources can be most
effectively and efficiently deployed to meet anticipated product requirements.
The marketing organization is also responsible for demand forecasting and
general support of the sales force, particularly at major accounts.  The
Corporation has many programs in place to heighten industry awareness of the
Corporation and its products, including participation in technical conferences,
publication of articles in industry journals and exhibiting at trade shows.

For the fiscal year ended June 25, 1999, the Corporation's international sales
represented 11% of net sales.  In the fiscal years ended June 26, 1998, and June
27, 1997, international sales were 21% and 19%, respectively, of net sales.  See
the discussion of segment information in the Corporation's 1999 Annual Report to
Shareholders, Note R, incorporated herein by reference.

At June 25, 1999, the Corporation's backlog of orders was $52.8 million. At June
26, 1998, the Corporation's backlog of orders was $24.0 million, and at June 27,
1997, it was $34.9 million. For additional information regarding backlog, refer
to Management's Discussion and Analysis of Financial Condition and Results of
Operation incorporated herein by reference to page 17 of the Registrant's 1999
Annual Report to Shareholders.

Research and Product Development
--------------------------------

The Corporation operates in an industry that is subject to rapid changes in
technology.  The Corporation's ability to compete successfully depends in large
part upon its ability to anticipate such changes.  Accordingly, the Corporation
is engaged in ongoing research and development activities that are intended to
advance existing product lines, provide custom-designed variations of existing
product lines and develop or evaluate new products. Research and development
activities for the three major product groups are conducted at the Corporation's
headquarters. The Corporation has an interdepartmental team, which assigns
product development priorities.  During the past fiscal year, research and
product development expenditures were primarily directed at expanding the
Corporation's AM fiber optic technology, network management systems and RF
amplifier line. The

                                       8
<PAGE>

Corporation also continued with product development process improvements to
reduce cycle time to design, develop and deliver new products, reduce
manufacturing costs and improve design quality.

During the fiscal years ended June 25, 1999, June 26, 1998, and June 27, 1997,
the Corporation spent approximately $9,038,000, $7,459,000, and $5,681,000,
respectively, on research and development related to AM fiber optic systems, RF
distribution equipment and network management.  Anticipated product development
initiatives focused on AM fiber optics, network management and other technology
areas are expected to result in increased research and development expense in
future years. No research and product development expenditures mentioned above
have been capitalized.

Competition
-----------

The broadband communications markets are dynamic and highly competitive,
requiring of those companies that compete in these markets substantial
resources, skilled and experienced personnel and a capability to anticipate and
capitalize on change.  The Corporation competes with other companies in each of
the markets in which it operates including, General Instrument, Scientific-
Atlanta, ADC Telecommunications, Antec and Harmonic, some of which are large
publicly traded companies that may have greater financial, technical and
marketing resources than we do.

The Corporation's products are marketed with emphasis on their quality and are
generally priced competitively with other manufacturers' product lines.  Product
reliability and performance, superior and responsive customer service, breadth
of product offering and an enhanced warranty program are several of the key
criteria for competition.  Other bases for competition include pricing and
technological innovation.

There are several competing equipment vendors selling network products in the
United States, a few of which have greater sales of similar equipment than the
Corporation. The Corporation, however, believes it offers a broader product line
in the RF distribution amplifier segment of the market, along with a growing
number of AM fiber optic and network management products.

Industry sources estimate that U.S. cable systems pass 97% of TV households in
the United States and in excess of 65% of those households are subscribers. In
face of this high consumer market penetration, there are alternative methods of
distributing entertainment video or information services to subscribers.  All of
the methods compete, to a limited extent, with conventional Cable TV services.
The alternative distribution technologies include off-air broadcast service,
Multipoint Multichannel Distribution Service (MMDS), LMDS, Satellite Master
Antenna Television (SMATV), DSL and DBS.

Employees
---------

The Corporation had approximately 1,947 employees as of September 20, 1999, of
which approximately 68% were engaged in manufacturing, inspection and quality
control activities. The remainder were engaged in executive, administrative,
sales, product development, research and technical customer services activities.
The technical staff includes 160 engineers with baccalaureate or more advanced
degrees and an additional 315 persons with at least two years of technical
college or military education equivalent to a two-year degree.

Suppliers
---------

The Corporation closely monitors supplier delivery performance and quality and
employs a strategy of limiting the total number of global suppliers to those who
are quality leaders in their respective specialties and who will work with the
Corporation as partners in the supply function.  Typical items purchased are die
cast aluminum housings, RF hybrids, printed circuit boards, fiber optic laser
transmitter assemblies and standard electronic components.  Some components,
subassemblies and modules necessary for the manufacture and integration of our
product are obtained from a sole supplier or a limited group of suppliers.  The
reliance on sole or limited suppliers, particularly foreign suppliers, involves
several risks, including a potential inability to obtain an adequate supply of
required components or subassemblies and reduced control over pricing, quality
and timely delivery of components.  The Corporation has experienced no

                                       9
<PAGE>

significant difficulties to date in obtaining adequate quantities of raw
materials and component parts.

The Corporation uses in-house vendor supply relationships to gain access to key
parts needed in the manufacturing process on a "just-in-time" basis.  The
Corporation has implemented a number of in-house vendor supply relationships to
date and will continue to establish such relationships in the future in order to
decrease vendor lead times and reduce on-hand inventory.

Business Combinations
---------------------

On July 9, 1999, the Corporation consummated a merger with Convergence, a
Georgia corporation, whereby Convergence became a wholly-owned subsidiary of the
Corporation.  The merger will enable the Corporation to offer an integrated
package of network management and support services and products.  The expertise
of Convergence in enabling high-speed digital data transmission and Internet
access over HFC networks by providing network design, activation and support
services will augment the Corporation's existing technical service capabilities.
In the merger, each outstanding share of common stock of Convergence was
converted into one share of the Corporation's common stock for an aggregate of
1,433,323 shares of the Corporation's common stock.  Each outstanding warrant to
acquire Convergence common stock was converted into a warrant to acquire the
Corporation's common stock for an aggregate of warrants to acquire 366,930
shares of the Corporation's common stock. The merger was accounted for under the
pooling-of-interests method of accounting.

On September 17, 1999, the Corporation consummated a merger with SVCI, a
California corporation, whereby SVCI became a wholly-owned subsidiary of the
Corporation. This acquisition will enable the Corporation to broaden and
strengthen its network distribution product offering by adding advanced fiber
optic products to its existing RF and fiber optic products. In particular, the
product offering will be strengthened with respect to headend fiber optic
equipment. As consideration in the merger, each outstanding share of common
stock of SVCI was converted into the right to receive .094534 shares of the
Corporation's common stock for an aggregate of 1,542,215 shares of the
Corporation's common stock (subject to reduction pursuant to certain escrow
arrangements). Outstanding stock options and warrants to acquire SVCI common
stock were converted into stock options and warrants to acquire the
Corporation's common stock, using the same conversion ratio (with appropriate
adjustment to the exercise price) for an aggregate of stock options and warrants
to acquire 387,227 shares of the Corporation's common stock. The merger was
accounted for under the pooling-of-interests method of accounting.

For additional information on Business Combinations, see the subsequent event
discussion in the Corporation's 1999 Annual Report to Shareholders, Note S,
incorporated herein by reference.

DISCONTINUED OPERATIONS

Digital Fiber Optics Transmission Products Segment
--------------------------------------------------

On July 10, 1997, the Corporation announced the discontinuance of its Digital
Fiber Optics Transmission Products segment in a nine-month, wind-down process.
The Corporation completed the wind-down of this operation as of March 1998.  The
Digital Fiber Optics Transmission Products segment provided products for long-
distance, point-to-point video, voice and data signal transmission applications,
primarily for telephony, distance-learning and other non-CATV markets.
Customers were primarily telephone companies, major broadcast companies and
educational institutions. The decision to discontinue this segment was based on
an assessment of the potential return on continued funding of product
development for the Corporation's proprietary digital technology versus other
opportunities for investments in the Corporation's core business, especially AM
fiber optics technology.

Research and development expenditures for this segment were $4,005,000 in fiscal
year 1997.

This business segment has been accounted for as a discontinued business segment,
and its results have been excluded from continuing operations for all periods
presented in the Corporation's consolidated financial statements, incorporated
herein by reference to pages 22 through 25 of the Registrant's 1999 Annual
Report to Shareholders.
