PART I

ITEM 1. BUSINESS

VideoServer, Inc. ("VideoServer" or "the Company") is a leading supplier of
networking equipment and associated software used to create multimedia
conferences that connect multiple users over wide area networks and allow them
to interact as a group. The Company's products, Multimedia Conference Servers
(MCSs), provide multipoint conferencing, as well as applications for conference
control, network management and bandwidth management. VideoServer's products
enable interoperability between dissimilar communications networks, video
conferencing systems and the encoding technologies used by those systems. The
Company's products, which combine audio, video and data information, are
positioned to become a key enabler of communications networks supporting
emerging collaborative multimedia applications.

VideoServer's objective is to expand its leadership position in the
conferencing market by developing and supplying products that enable multipoint
conferencing, whether through end-user multimedia networks or carrier-provided
conferencing services.

The Company provides Multimedia Conference Servers to a wide variety of
technology and distribution partners, including leading videoconferencing
equipment suppliers, telephone carriers, private conferencing service providers,
computer companies and PBX suppliers. The Company believes that it was the
largest supplier in annual shipments of multimedia conference servers in 1994,
1995, and 1996.

In March 1997, the Company entered into a definitive purchase agreement with
Promptus Communications to acquire certain assets comprising Promptus' network
access card business, for approximately $21,000,000 in cash and stock. The
transaction is expected to close in the second calendar quarter of 1997.
Promptus manufactures and markets a comprehensive line of digital network access
products used for a variety of applications, including videoconferencing, ISDN
Internet access, remote LAN access, and high-speed file transfer. Network
access technology is an important component of the Company's MCS products, and
Promptus is a significant supplier to the Company.

INDUSTRY BACKGROUND

VIDEOCONFERENCING

The multimedia conferencing market has evolved from videoconferencing. In
the late 1980s, with increasing numbers of conferencing endpoints installed and
customers desiring to connect multiple locations into the same conference,
videoconferencing equipment suppliers introduced multipoint control units (MCUs)
to transfer video and audio signals between all conference participants.
However, because of the proprietary nature of the encoding used, video terminals
and associated multipoint control units from different manufacturers were not
interoperable. In December 1990, the International Telecommunications Union
(ITU) introduced the H.320 standards for videoconferencing over switched digital
circuit networks to provide a framework for equipment from different
manufacturers to communicate with each other. Compatibility is particularly
important for communication via these networks, since the advantage of these
services is dial-up communications without regard to the type of equipment being
used at the receiving ends of the transmission.

In recent years, lower-priced, standards-based products emerged that have
expanded the market for videoconferencing systems. Room systems that were once
priced in the $100,000 to $200,000 range are now priced as low as $8,000. In
addition, increasing competition between network carriers, and increasing demand
for applications such as Internet access, are leading to wider availability and
significantly declining costs of digital lines.

With the introduction of chip sets incorporating ITU standards, a growing
number of companies have entered the desktop videoconferencing market, either
with stand-alone complete PC-based systems or with board sets that plug into
personal computers. Companies shipping H.320 compliant desktop conferencing
products include

3
4
British Telecom, Compression Labs, IBM, Intel, Olivetti, PictureTel, VTEL and
VCON. The costs of such desktop conferencing products have rapidly declined with
the introduction of more powerful chip sets and further miniaturization of
components such as cameras and monitors. Since early 1994, desktop conferencing
subsystems have dropped in price from $6,000 per seat to less than $1,500, with
some products available for as low as $1,000. As with the decrease in the price
of room systems, this decrease in price has fueled demand for desktop endpoints.

Extending the reach of conferencing, in November 1995 the ITU introduced the
H.324 standard for low bit rate video, enabling videoconferencing over analog
lines using PCs or videophones. This is expected to bring conferencing
capability to an entirely new segment of end users, including those in smaller
businesses and homes. PC vendors such as AST, Compaq, Hewlett-Packard, IBM,
Sony, and Toshiba, and modem suppliers such as Boca Research and U.S. Robotics
began offering H.324 conferencing capabilities late in 1996.

In May 1996, another important expansion of conferencing standards was
realized with the introduction of the H.323 standard governing real-time
collaboration over local area networks, intranets, and the Internet. Enabling
conferencing over traditional business networks provides a foundation for the
adoption of this application as a mainstream business tool. Vendors such as
Intel, PictureTel, and Microsoft have announced their intention to introduce
H.323 based endpoints in 1997.

Each of these endpoints, whether room systems or desktop systems, require
server resources to conduct a multipoint conference. A larger installed base of
endpoints is expected to lead to more multipoint conferencing, and therefore to
a greater demand for the Company's MCS products.

COLLABORATIVE MULTIMEDIA APPLICATIONS

Concurrent with advances in videoconferencing, significant investments have
been made in software to extend traditional desktop computing applications into
conference enabled real-time information sharing tools. Collaborative data
conferencing applications are emerging that redefine the way groups can work
together. With the ability to see and hear one another over telecommunications
lines and share a common desktop application like a white board, spreadsheet or
word-processing document, participants can share ideas and collaborate in real
time to improve the work product.

In response to the emerging customer demand for multimedia applications, in
February 1996 the ITU extended the T.120 standards for collaborative multimedia
conferencing wherein video, audio and data information can be shared between
endpoints in a multipoint setting. In 1996 Microsoft bundled a standards-based
realtime voice and data conferencing package, NetMeeting, into its Windows
operating system. This product will provide an embedded collaborative capability
for potentially millions of PC users. In addition, Intel and IBM are offering
collaborative desktop applications with optional audio and video capabilities
sold through retail computer channels. Fundamental to the architecture of these
products is the presence of a multimedia conference server to provide the
multipoint link and data distribution mechanism among all the endpoints.

CARRIER-PROVIDED SERVICES

The intense competition among carriers has increased the demand for
technologies that allow carriers to provide additional value-added services.
Multimedia conferencing technology offers such an opportunity, and carriers are
initiating collaborative multimedia conferencing services that provide on-demand
multipoint conferencing capability allowing users to connect their terminals to
multimedia conference servers located in the carriers' central offices.

A NEW CLASS OF NETWORK EQUIPMENT

These trends -- the growth in room systems and desktop videoconferencing,
growth in collaborative desktop conferencing and expansion in services offered
by carriers -- are driving the need for sophisticated, networked multimedia
conference servers.

THE VIDEOSERVER SOLUTION

VideoServer was founded in 1991 to develop a new generation of networking
equipment architected for the videoconferencing market as well as the emerging
multimedia conferencing market. The VideoServer MCS product line is built on an
industry standard hardware and software platform that combines a powerful set of
real-time conferencing applications with management tools and network
connectivity features that address today's customer requirements and are
positioned to meet emerging requirements. These requirements include:

INTEROPERABILITY. VideoServer's Multimedia Conference Servers today provide
transparent interoperability among many different kinds of endpoints such as
room videoconferencing systems, desktop video terminals, and regular telephones
in the same conference, using combinations of voice, video, and data. In the
future, this level of interworking will be expected to encompass emerging
conferencing endpoint technologies such as data conferencing computers,
audio-graphics systems and videophones. Similarly, interoperability must be
provided between the many different brands of equipment and applications. The
technology also must be able to accommodate various encoding algorithms used to
compress multimedia information. The Company has expended substantial effort to
make its MCS interoperable with the products of virtually all suppliers of
standards-based videoconferencing terminals. In many cases this has required
subtle accommodations in the MCS for the specific characteristics of each brand
of endpoint due to the manufacturer's implementation of the ITU standards and
product performance. When different encoding technology is employed in terminals
for audio algorithms, the MCS provides the transcoding needed to deliver the
audio mix to each endpoint in the proper algorithm for that endpoint.

CONNECTIVITY. Conference servers must be able to provide gateways between
diverse network services and between multiple carriers. While today's servers
provide connectivity largely to T-1, ISDN, private digital networks, and analog
voice networks, in the future, endpoints are expected to be connected to
ethernet and token ring local area networks, the Internet, and to advanced
networks based on ATM. In addition, as carriers add features to their networks,
conference servers must be able to support them.

FUNCTIONALITY. In addition to video switching and audio mixing, application
features are needed to facilitate ease of operation, perform centralized
processing, interconnect with traditional data network servers and deliver many
new kinds of network information. These network servers will be required to
scale throughout the enterprise, provide redundancy for high reliability and
incorporate network management capabilities.

PRODUCTS

The Company provides technology advances to its OEM and carrier customers
through products that incorporate rapid standards deployment, extensive feature
content, scalability, network flexibility and interoperability. The Company
believes that its technology leadership enables its customers to reduce their
time-to-market and their own product costs, and that the Company's technology
relationships with customers allow it to anticipate market requirements critical
to its products.

The Company's products have been designed within a scaleable, modular
architecture to allow the customer to add capacity, processing power and
conferencing features as the customer's network and application requirements
grow. Using a common set of hardware and software building blocks, customers can
choose from a wide range of product configurations that differ in capacity,
price, network connectivity and features, all of which


5
6
share the same operating software user interface. The product may be configured
for use in customer premises environments or may be configured with specialized
packaging for use in a telephone carrier's central office setting.

The MCS product line includes a number of basic platform configurations that
are expanded by the customer's selection of optional processing modules and
software applications. The platforms, configured for the typical end-user, range
in list price from under $25,000 to more than $200,000. Each MCS configuration
is built from a common set of processing modules, network interfaces, software
systems and optional features.

The following table lists the basic chassis configurations offered by the
Company and the typical target market and application in which each is used. In
this table, user capacity is a measure of the number of simultaneous conference
participants that can be connected to the MCS.

The VideoServer MCS can be directly connected to public networks (either T-1
or ISDN networks, or both) or private networks. The T-1 interface can be
configured as either a full or fractional T-1 (FT-1). If FT-1 service is
selected, multiple FT-1 circuits may be multiplexed and delivered by the network
to the MCS in a single T-1 pipe. ISDN Primary Rate Interface (PRI) support
allows the MCS to cost-effectively support multiple basic rate terminal
connections across a single interface. ISDN Basic Rate Interface (BRI) support
offers a cost effective solution for customer premise applications not requiring
PRI. The MCS supports the various ISDN network protocols used in the United
States, the United Kingdom, France, Germany, Japan, Australia and the
European-wide standard, and thus can be used worldwide.

The Company offers add-on software to its installed base in the form of
either major new software releases or unbundled software options. Customers may
purchase new software releases on an as-needed basis or as part of a maintenance
agreement. Unbundled software options are priced separately and are not part of
maintenance agreements.

MARKETS AND CUSTOMERS

VideoServer markets its products to Original Equipment Manufacturers (OEMs),
which generally resell the Company's products to end-users, and to service
providers, including public and private telephone carriers, which generally
offer conferencing services based on the Company's products. This distribution
strategy focuses on four types of customers: conferencing equipment
manufacturers and resellers, telephone companies as conferencing service
providers, computer systems and workstation companies, and PBX and network
equipment suppliers.

Traditional videoconferencing equipment suppliers have historically
represented the primary market for delivering conferencing equipment to users.
The Company has relationships with most of the significant videoconferencing
suppliers around the world, including Compression Labs, Inc. (CLI) and
PictureTel Corporation in the United States, and British Telecom, GPT Video
Systems (a division of the UK-based GPT Limited), and Societe Anonyme de
Telecommunications (a division of the French-based Sagem Group), three of the
leading European suppliers of conferencing products. Each is offering the
Company's products to its customers under private label. The Company also has
agreements with leading Japanese manufacturers, including Sony Corporation,
which resells the products globally, as well as NEC America Inc., Fujitsu
Business Communications Systems, Inc. and Panasonic Corporation, which remarket
the products primarily in English-speaking countries worldwide.

Telecommunication service providers are increasingly seeking to
differentiate themselves by offering multimedia conferencing services to
customers who desire on-demand conferencing capability without installing their
own conference servers. The Company markets its products and services directly
to public and private telecommunications service providers, including
Interexchange Carriers (IXCs) such as AT&T, MCI and Sprint, Regional Bell
Operating Companies (RBOCs) such as BellSouth and Southwestern Bell, a number of
private conferencing service providers in the U.S. such as Link VTC and
1-800-Video On, and to international Post Telephone and Telegraph companies
(PTTs) in Europe and Asia, such as British Telecom, Deutsche Telekom, France
Telecom, and NTT.

As conferencing moves to desktop computing, computer systems companies are
beginning to address the emerging collaborative multimedia market. The Company
believes these companies view multimedia applications as a strategic technology
thrust that will fuel demand for computing resources and network bandwidth.
Since late 1993, Intel Corporation and VideoServer have participated in joint
development and marketing of products for the conferencing market. In late 1996,
the Company and Compaq Computer announced their intention to work closely with
Compaq's value-added resellers in North America to incorporate VideoServer
technology into Compaq servers.

With the continued expansion of standards, network equipment and PBX
companies, whose products form the data and telecommunications backbone of the
enterprise network, are beginning to incorporate conferencing technology into
their product lines. In late 1996, the Company announced an OEM arrangement with
Cisco Systems, initially under which the Company will provide standards-based
conferencing gateways to Cisco for integration into certain of its enterprise
routers. Additionally, major PBX companies such as Nortel and Siemens/Rolm, who
are expanding their traditional audio-based offerings to include video and data
capabilities, have begun to resell the Company's MCS products.

The Company's agreements with its customers generally do not include minimum
purchase requirements and are non-exclusive. In 1994, CLI and British Telecom
accounted for 55% and 12% of net sales. In 1995, CLI, PictureTel, who became a
customer during 1995, and BellSouth accounted for 23%, 19% and 18% of net sales.
In 1996, PictureTel and CLI accounted for 43% and 10% of net sales. Sales to
international customers accounted for 29%, 25% and 32% of the Company's net
sales for the years ended December 31, 1994, 1995 and 1996.

VideoServer conducts its sales and marketing activities from its principal
offices in Burlington, Massachusetts, as well as from four other North American
sales offices and its European headquarters located in the United Kingdom.

RESEARCH AND PRODUCT DEVELOPMENT

The Company believes that its future success depends on its ability to
continue to enhance and expand its existing products and to develop new products
which maintain its technology leadership. VideoServer has invested, and expects
to continue to invest heavily, in the development of products and core
technologies. Extensive product development input is obtained from OEM partners,
from service providers, from end users, and through the Company's active
participation and leadership in industry groups responsible for establishing
technical standards such as the ITU and the IMTC .

Since its founding, the Company's research and development effort has been
directed towards the development of standards-based conference server
technology. In concert with the evolution of industry standards, these efforts
currently are focused on extending the breadth of network services supported
beyond switched digital services to include local area networks, corporate
intranets, the Internet, and ATM. This includes the development of multipoint
products for particular network platforms and gateway products to provide
interoperability between dissimilar network types. Development is also underway
to support emerging data conferencing applications, provide additional
conferencing management capabilities including enhanced user interfaces, and to
add higher capacities to the product family. The Company is extending and
accelerating its



8
9
efforts through development relationships with its customers. The Company
receives funding under certain of these arrangements which, when earned, is
recorded as a reduction of research and development expense in the Company's
financial statements.

At December 31, 1996, VideoServer's research and development staff consisted
of 77 employees, including 65 software engineers and 12 hardware engineers. The
Company's net research and development expenditures were $3.3 million, $5.3
million and $7.8 million in 1994, 1995 and 1996, representing 21%, 19% and 16%
of net sales in those years. Development funding from customers of $340,000,
$1,000,000 and $1,150,000 was recorded as a reduction of research and
development costs in 1994, 1995 and 1996. All software development costs have
been expensed as incurred because costs eligible for capitalization have not
been material to date.

In January 1997, the Company began to establish an international development
operation in the United Kingdom.

CUSTOMER SUPPORT AND SERVICE

The Company provides technical support and services to its resellers and
customers. A high level of continuing service and support is critical to the
Company's objective of developing long-term relationships with customers. The
Company's resellers install, maintain and provide on-site and headquarters-level
technical support of products to their end-user customers, and VideoServer
provides comprehensive problem management, training, diagnostic tools, repair
services and spare parts to facilitate and supplement these efforts. The Company
installs, maintains and directly supports products sold to its direct customers.

The Company offers a technical support hotline to its resellers and
customers. Network support engineers answer technical support calls placed by
the support engineers of the Company's resellers and by its direct customers.
The engineers generally provide same-day responses to questions that cannot be
resolved during the initial call. The products are designed with advanced remote
diagnostic capabilities that permit a reseller's or the Company's support
engineers to immediately begin the process of diagnosing any problems in the
field, thereby reducing both response time and cost. When necessary, however,
support engineers are dispatched to the customer's facility.

The Company warrants its software products for 90 days. During this 90-day
warranty period, the Company will investigate all reported problems and will
follow escalation procedures to provide resolution. The Company warrants its
hardware products for 12 months. During this warranty period, the Company will
repair or replace any failed hardware component. The Company also offers
post-warranty support programs ranging from services on a time-and-materials
basis to full-service contracts on a 24-hour, 7-days-a-week basis, and a full
suite of training courses.

MANUFACTURING

The Company's manufacturing operations consist primarily of materials
planning and procurement, quality control of materials, components and
subassemblies and final product configuration and testing. The Company designs
the significant hardware subassemblies for its products and uses independent
third-party contract assembly companies to perform printed circuit board
assembly. The Company configures and tests the hardware and software in
combinations to meet a wide variety of customer requirements. The Company uses
automated testing equipment, "burn-in" procedures and comprehensive inspection
and statistical process control testing intended to assure the quality and
reliability of its products. The Company has received the International Standard
Organization (ISO) 9002 certification for quality.


9
10
Although the Company generally uses standard parts and components for
its products, certain components, including key digital signal processors from
Texas Instruments, are presently available only from single sources or from
limited sources. The Company has no supply commitments from its vendors,
including Texas Instruments, and generally purchases components on a purchase
order basis as opposed to entering into long term procurement agreements with
vendors. The Company has been able to obtain adequate supplies of components in
a timely manner from current vendors, or when necessary to meet production
needs, from alternate vendors. The Company believes that, for the Texas
Instruments digital signal processors in particular, alternative sources of
supply would be difficult to develop over a short period of time and an
interruption in supply or a significant increase in the price of these
components would adversely affect the Company's operating results and business.

Because of the generally short cycle between order and shipment and because
the majority of the Company's sales in each quarter results from orders booked
in that quarter, the Company does not believe that its backlog as of any
particular date is indicative of future sales levels.

COMPETITION

The market for communications products is intensely competitive and is
subject to rapid technological change. Although to date the Company has
experienced limited competition from products with comparable capabilities, the
Company expects competition to increase significantly in the future. Currently,
the Company's principal competition from producers of multipoint control units
comes from Lucent Technologies, and to a lesser extent from VTEL Corporation.
Other companies such as Multilink, Teleos (a division of Madge Networks) Accord,
Databeam, and Outreach, have introduced or announced their intention to
introduce products which could be competitive with the Company's products.
Furthermore, PictureTel Corporation, currently the Company's largest customer,
and Radvision have announced their intention to introduce products related to
the new H.323 standards which may be competitive with products the Company
currently has under development, and others are expected to enter the H.323
conferencing market. This additional competition could adversely affect the
Company's sales and profitability through price reductions and loss of market
share. In particular, should one or more of the Company's current customers,
including videoconferencing equipment suppliers, telecommunications carriers or
traditional network equipment vendors choose to provide or distribute
competitive products (including their own products) and services, the Company's
business could be materially adversely affected. Many of the Company's current
and potential competitors have substantially greater financial, marketing and
technical resources than the Company.

The principal competitive factors in the market for multimedia conference
servers are, and are expected to continue to be, breadth of network services
supported, conformance to industry standards, price per port, performance,
network management capabilities, transcoding capabilities, reliability and
customer support. While the Company believes it presently competes favorably in
all of these areas, there can be no assurance that it will continue to do so.

PROPRIETARY RIGHTS

While the Company has applied for several patents, it currently holds only
one U.S. patent relating to its existing products, and relies on a combination
of contractual rights, trade secrets and copyright laws to establish and protect
its intellectual property rights. The Company believes that, because of the
rapid pace of technological change in the data communications and
telecommunications industries, the intellectual property protection for its
products is a less significant factor in the Company's success than the
knowledge, abilities and experience of the Company's employees, the frequency of
its product enhancements, its relationships with its partners, the effectiveness
of its marketing activities, and the timeliness and quality of its support
services.


10
11
The Company is subject to the risk of adverse claims and litigation
alleging infringement of the intellectual property rights of others. In December
1994, the Company settled a patent infringement litigation brought against it by
Datapoint Corporation (Datapoint) for a cash payment by the Company of $500,000.
There can be no assurance that additional third parties will not assert claims
against the Company in the future with respect to the Company's current or
future products or that any such claims would not require the Company to enter
into license arrangements or result in protracted and costly litigation,
regardless of the merits of such claims. No assurance can be given that the
Company would prevail with respect to any such claim, or that a license to
third-party rights, if needed, would be available on acceptable terms.

Patent infringement litigation still exists between Datapoint and two of the
Company's largest customers. In addition, Datapoint has written inquiry letters
to a significant number of others in the videoconferencing market offering to
sell them nonexclusive licenses under certain Datapoint patents in the
videoconferencing field (the Datapoint Patents). While the validity or scope of
the Datapoint Patents has not been adjudicated by a court, Datapoint has, in
effect, asserted that the Datapoint Patents cover certain aspects of multipoint
videoconferencing operations involving terminals and multipoint control units,
including the Company's MCSs. As a result of the December 1994 settlement, the
Company obtained a nonexclusive license for its MCS under the Datapoint Patents,
which license includes limited rights for the products and services of the
Company's customers. However, the conferencing market in general, and the
Company's future sales and operating results in particular, could be adversely
affected as a result of ongoing uncertainties regarding the Datapoint Patents.
Such uncertainty, and any related potential impact, is likely to exist until the
validity of the patents is adjudicated.

EMPLOYEES

At December 31, 1996, the Company employed a total of 193 persons, including
77 in research and development, 73 in sales, marketing and customer support, 24
in manufacturing and 19 in finance and administration. Thirteen of the Company's
employees were located in the United Kingdom and the remainder were located in
the United States. None of the Company's employees are represented by a labor
organization and the Company believes that its relations with employees are
good.

Competition for qualified personnel in the computer networking and
communications industry is intense. VideoServer believes that its future success
will depend on its continued ability to attract and retain qualified personnel.
