PART I

Item 1. Business

General

We were incorporated under the laws of the State of Israel in
January1992, commenced operations in October 1992 and commenced sales of our
products in the fourth quarter of 1994. Before that time, our operations
consisted primarily of research and development and recruiting personnel. We are
a public limited liability company under the Israeli Companies Law 1999 and
operate under this law and associated legislation. Our registered offices and
principal place of business are located at 24 Raoul Wallenberg Street, Tel Aviv
69719, Israel. Our address on the Internet is www.radvision.com. The information
on our website is not incorporated by reference into this annual report.

With over a decade in business, RADVISION is the industry's leading
provider of high quality, scalable and easy-to-use products and technologies for
videoconferencing, video telephony, and the development of converged voice,
video and data over IP and 3G networks. Hundreds of thousands of end-users
around the world today communicate over a wide variety of networks using
products and solutions based on or built around RADVISION's multimedia
communication platforms and software development solutions.

We have approximately 450 customers worldwide including Alcatel, Cisco,
FastWeb, NTT/DoCoMo, Philips, Panasonic, Samsung, Shanghai Bell, Siemens, Sony
and Tandberg.

In the beginning of 2001, we created two separate business units
corresponding to our two product lines to enable our product development and
product marketing teams to respond quickly to evolving market needs with new
product introductions.

Our Networking Business Unit, or NBU, offers one of the broadest and
most complete set of multimedia communication and videoconferencing network
solutions for IP, ISDN, SIP and 3G-based networks, supporting most end points in
the industry today. These products are sold primarily to resellers and OEMs who
use this infrastructure to develop and install advanced IP and ISDN-based
communication systems for enterprise customers. The NBU also provides service
providers, both 3G wireless and wireline, with integrated solutions that enable
the delivery of converged IP-based multimedia streaming and video telephony
applications to corporate customers as a managed service, residential broadband
customers, and 3G subscribers worldwide.

Our Technology Business Unit, or TBU, is a one-stop-shop of voice and
video over IP and 3G Development toolkits. The TBU provides protocol development
tools and platforms, as well as associated solutions such as testing platforms
and IP phone toolkits that enable equipment vendors and service providers to
develop and deploy new IP and 3G-based converged networks, services, and
technologies. Our TBU also provides professional services to our customers,
assisting them to integrate our technology into their products.
RADVISION's TBU

solutions include developer toolkits for SIP, MEGACO/H.248, MGCP, H.323, and
3G-324M. It also includes RADVISION's ProLab(TM) Test Management Suite and IP
phone toolkit. Today you may find RADVISION toolkits implemented in a wide range
of environments from chipsets to simple user devices like IP phones, and from
integrated video systems through carrier class network devices like gateways,
switches, soft switches and 3G multimedia gateways.

Our Strategy

Our goal is to be the leading provider of innovative products and
technologies that enable real-time multimedia collaboration (voice, video and
data) communication over packet networks. We provide solutions at every level -
protocol developer toolkits, professional services, network infrastructure, and
even integrated solutions that compliment the communication solutions of other
vendors such as those from Cisco and Microsoft. We believe that the combination
of offering IP-centric networking products and software toolkits uniquely
positions us as a key enabling vendor in the evolution of IP communication. Both
of our product lines are essential for building IP networks that support real
time voice and video communication with full interoperability with legacy
ISDN/PSTN networks and technologies. Key elements of our strategy include the
following:

o Maintain and Extend our Technology Leadership. We believe that we have
established ourselves as a technology leader in providing
core-enabling technology for a broad range of IP and 3G communication
products and services, such as our announcement in 2003 of support for
SIP in our infrastructure products - one of the first in the industry
to do so. We have accumulated extensive knowledge and expertise as
designers and developers of commercial products and technology for
real-time packet-based communication. We place considerable emphasis
on research and development to expand the capabilities of our existing
products, to develop new products and to improve our existing
technology and capabilities. We believe that our future success will
depend upon our ability to maintain our technological leadership, to
enhance our existing products and to introduce on a timely basis new
commercially viable products addressing the needs of our customers. We
intend to continue to devote a significant portion of our personnel
and financial resources to research and development.

o Enable the Migration of Visual Communication from the conference room
(videoconferencing) to the desk top, the home, and on the road over 3G
(video telephony and multimedia communication). We have been working
with leading technology vendors such as Cisco and Microsoft as well as
aggressively developing partnerships with broadband and wireless
service providers to transform videoconferencing from a meeting room
application to a new mode of personal communication.

o Strengthen and Expand our Relationships with OEM Customers. We have
established and continue to maintain collaborative working
relationships with many OEMs in the IP communication market, including
Cisco, Samsung, Siemens, Sony and Tandberg. We work closely with our
OEM customers to integrate our products and core technology into their
solutions. Our core technology and our system design expertise enable
us to assist these customers in the development of complete solutions
that contain enhanced features and functionality compared to
competitive alternatives. We strive to establish long-term

relationships with our OEM customers by starting with a few products
and subsequently expanding these relationships by increasing the
number and range of products sold to these customers. We intend to
expand the depth and breadth of our existing OEM relationships while
initiating similar new relationships with leading OEMs focused on the
IP communication market.

o Become a Key Enabling Technology Solution for IP Communication. We
continue to strive to ensure that our infrastructure solutions are key
enabling components in larger solution vendors' portfolios. To that
end, in 2003, we announced that our viaIP multimedia communication
platform supports multipoint and multidevice functionality within
Microsoft's Office Live Communication Server 2003 platform for desktop
communication. Additionally, RADVISION is the key enabling technology
in a number of telecom equipment vendors' 3G communication platforms -
enabling real-time multimedia services.

o Continue to Offer New and Enhanced Products and Features. We believe
we have consistently been either first, or among the first, to market
products that support real-time voice, video and data communication
over packet networks. We were the first-to-market with IP gateways
that provide combined voice, video and data functionality, first to
market with software development kits for the development of
H.323-compliant IP communication products and applications, and this
year, the first to announce support for SIP (Session Initiation
Protocol) in our infrastructure platform. We intend to utilize our
technological expertise as a basis for market leadership by striving
to be first-to-market with new and enhanced products and features that
address the increasingly sophisticated needs of our customers and the
evolving markets they serve. In addition, we believe that our
participation in the drafting of industry standards gives us the
ability to quickly identify emerging trends enabling us to develop new
products and technologies that are at the forefront of technological
evolution in the IP communication industry.

In 2003, our TBU expanded its product offering to include a new
direction for our company with the first of our toolkits that not only provide
protocol developer suites but actual reference designs. The first product is an
IP Phone toolkit, which provides all the functionality and call control, as well
as supporting multiple signaling protocols, that enables developers to more
easily develop IP phones. Additionally, in 2003, we announced a number of
upgrades to our toolkits to maintain our lead in supporting the latest versions
of signaling standards. TBU also announced in 2003 that it had ported its
developer solutions to a number of new emerging platforms including Linux and an
embedded chip operating system. Finally, in 2003 we launched our Professional
Services division, which features a team of highly skilled developers who are
available to assist clients in developing products using RADVISION toolkits and
protocol stacks. These introductions have helped us maintain our position as the
premier, one-stop-shop for all voice and video technologies over IP and 3G. We
also believe that they reinforce RADVISION's leadership position as a protocol
toolkit technology expert.

In 2003, our NBU introduced a number of very significant new
technologies and platforms for videoconferencing and multimedia communication.
These introductions included an MCU version 3.2 (Multipoint Conferencing Unit)
which broke ground in both

price and performance as well as in its support of SIP and the new H.264
compression standard. We also introduced new versions of our INVISION platform
for enterprise communication as well as new scheduling and network management
tools. Finally, and perhaps most importantly, we announced full support of
Microsoft's Live Communication architecture, a powerful new desktop
communication architecture for converged voice, video, and data collaboration

We expect to continue to introduce new or enhanced products in 2004,
including upgrades to our software toolkits and improvements to our
videoconferencing and multimedia communication product lines that include added
functionality. In addition, we plan to:

o Deepen the Distribution Channels for our Products. We intend to
continue to focus our sales and marketing efforts on deepening the
relationship with our distribution channels. Channel partners provide
us feedback from their customers, the end-users of our products, which
gives us valuable insight into evolving industry trends and customer
requirements. OEMs, resellers and systems integrators are all
important channel partners for our products. They provide us with
increased market presence through their distributor relationships and
existing customer base. In addition, endorsements by key channel
partners strengthen our brand name awareness.

o Leverage Service Provider Opportunities. We are working closely with
telecom equipment provides, 3G mobile carriers, and wireline service
providers to enable multimedia communication in the home and on the
road. We are seeing initial success and expect to continue to help
grow that market - particularly in the 3G space where we are in
several active trials globally.

o Enable Desktop Conferencing and Communication Through Strategic
Partners. We will continue our efforts to maintain our position as a
key enabling solution provider for major vendors' activities to drive
visual communication beyond the meeting room and onto the desktop. We
intend to strengthen our relationship with Microsoft and its sales
channels. We also expect to leverage our close relationship with Cisco
and what they are doing in enterprise video telephony by virtue of our
AVVID certification announcement in early 2004.

o Continue our Active Involvement in Shaping Industry Standards for IP
Communication. We actively participate in and contribute to the
formulation of standards for IP communication. We intend to continue
our active involvement in the organizations that define the standards
for real-time communication over next generation packet networks. Our
knowledge and expertise gained in participating in the development of
these industry standards enable us to be among the first to market our
products and technology based on new standards adopted. We are
continually improving, enhancing and expanding our core competency in
real time IP communication protocols including H.323, SIP, MGCP and
MEGACO. Because of our involvement in defining these IP communication
standards, we believe that we are well-positioned to quickly develop
enhanced functionality and new products based on multiple protocols.

The following discussion of our business is separated into two sections:
the first addresses our videoconferencing network infrastructure section, or
NBU, and the second addresses our software developer toolkit business, or TBU.
In each section we will provide an overview of our products, our competitive
advantage, and industry trends that are beneficial to our business.

and Results of Operations for financial information relating to our NBU.

NBU Product Benefits

While our products thoroughly support ISDN, we believe that the
principal competitive advantage of our family of solutions is our IP expertise.
Our products are the leading visual communication infrastructure solutions in
the industry today by virtue of our unmatched technological innovation in five
key areas:

Native IP Routing. All competing solutions come from the legacy ISDN
world, with an ISDN-based switching fabric (TDM backplane). This means that for
an IP end point to IP end point session, every IP stream has to be translated to
"ISDN" in order to be switched by the system, and then translated back to IP to
be forwarded on. In contrast, we offer an IP backplane, meaning IP sessions are
routed natively, with no translation. RADVISION solutions all perform flawlessly
in supporting ISDN-only or hybrid IP/ISDN networks, providing an ideal platform
as a network migrates from ISDN to IP while preserving the customer's earlier
investment in legacy equipment.

Distributed Architecture. The capacity of the viaIP400 is unmatched in
the industry. Because of its unique architecture, the viaIP system is not
limited to a single chassis. As a result, a single MCU (multiconferencing unit)
can support up to six gateway boards, achieving a capacity of up to 600 hundred
simultaneous calls on the same chassis and limitless calls on a stacked
multi-chassis system. Additionally, due to the system's IP architecture, the
entire infrastructure does not need to be mounted in a single integrated rack
but can be distributed throughout a network. By distributing intelligence
throughout the network, the enterprise benefits with increased redundancy,
network traffic optimization, resource management, and high scalability.

Full Protocol Support. In addition to supporting both ISDN and H.323,
our solution also supports SIP and 3G-324M - two emerging protocols for desktop
and mobile communication.

Specialized Network Architecture Provides Unparalleled Redundancy.
RADVISION has taken advantage of advanced chipsets to put an entire voice and
video processing matrix, with multiple chips, on a single board. Each board
supports a portion of the total calls. The boards are wired in parallel over a
shared backplane. In the event of a board failure, the system would

shift ongoing calls to another board, thereby reducing the overall capacity of
the device but not dropping any calls.

Advanced Chips Provide Superior Performance and Functionality at a Lower
Cost. As an IP-centric platform with ISDN interworking, the RADVISION solution
is able to take advantage of the advances in integrated IP multifunction chip
technology. The system's on-board CPU is a PPC 400Mhz. We also use Texas
Instrument's revolutionary C6x programmable 100Mhz chipset for call
functionality.

IP Protocol Expertise. RADVISION is a leader in developing and
delivering advanced voice and video protocols over IP networks, primarily H.323
and SIP. As a result, our solutions support the most recent versions of each of
the signal protocols with the associated features they enable. Also, as most IP
videoconferencing endpoints in the market use RADVISION protocol stacks, our
solutions are completely interoperable with virtually every standards-based end
point on the market today.

Specific Breakdown of Features and Functionality

o Greater port density for IP video and voice calls - The RADVISION
platform supports 48 IP video calls at 384Kbps and 150 voice calls on
a single MCU card.

o Powerful Price/Performance - RADVISION doubled the port capacity of
768 Kbps calls in its MCU without any associated increase in product
list price. The new list price for a 768 Kbps call now starts at
$1,354 per port - a new benchmark in the industry.

o Number of conferences - A conference with RADVISION is a logic entity.
As such, there can be as many conferences as the number of calls to
the MCU.

o Multiple layouts - RADVISION supports a maximum of 23 layouts.

o In addition to ISDN (H.320) and IP (H.323, SIP), RADVISION's platform
also supports a wide variety of additional voice and video protocols,
including MEGACO and 3G-324M (for 3G wireless videoconferencing).

Visual Communication Market Trends

Evolution in the Way People Communicate. With the need for greater
efficiency and the importance of accurate communication, companies are turning
to new ways of communicating to enable remote parties to interact as if they
were in the same room. Conference calls and e-mail usage have increased
dramatically and Instant Messaging (IM) is being adopted increasingly in the
enterprise and home. This trend to new forms of communication has also sparked
enterprises to explore multimedia applications that provide advanced voice,
video and data experiences to maximize information flow, whether in a group
meeting or person to person.

Major Vendors Providing Video Telephony and Desktop Multimedia
Communications. 2003 saw the entry of Microsoft into the desktop multimedia
communications space with the

launch of its Live Communications server and Windows Messenger. It also saw
Cisco's acquisition of Latitude and its flagship product MeetingPlace. Both of
these architectures are for personal (desktop) multimedia conferencing and
communications. RADVISION - due to its unique IP-based architecture and support
of standards such as SIP - is in a strong position to provide complementary
solutions and/or capitalize on the strong marketing and solution trends that
these two large companies, as well as others in the industry, including Nortel
with its own desktop solution, are offering to the IT manager and CEO/CIO/CTO.

The Spread of Video Telephony Beyond the Enterprise and into the Home
and on the Road. End users are beginning to use multimedia applications for
their communication not only in the enterprise through meeting rooms and
desktops, but also at home and on the road. RADVISION is experiencing this trend
and is realizing sales from service providers as they are beginning to use our
technology to deliver video telephony services to residential homes as just
another broadband application like Internet access and video-on-demand.
Additionally, 3G wireless providers are increasingly looking to deliver
real-time multimedia content to their mobile subscribers. RADVISION is well
suited to play a role in this market with its 3G-324M architecture and
multimedia services support.

The Evolution from ISDN to IP. Traditional (legacy) videoconferencing
systems are ISDN-based. This means expensive technology, a separate high-speed
line into the office for video only, and a separation between video running over
ISDN and data running over IP. However, IP-based videoconferencing recently has
been gaining greater acceptance. As companies put voice over their IP networks
(VoIP), they are also beginning to put video over their IP networks. RADVISION
is the pioneer in videoconferencing over IP. Because its technology is sited in
the core of the IP network, RADVISION's solutions enable network managers to
leverage their installed high speed data networks, merge video with voice and
data applications (running over the same IP connection) and centrally manage a
host of video end points, from meeting room to desktop to PC based systems, and
eventually to wireless video phones.

Technology Business Unit

RADVISION's TBU provides standards-based toolkits and testing systems
for the development of real-time voice, video and data communication solutions
over packet networks and 3G networks.

TBU Products

As a driving force behind evolving technologies of real-time IP
communication, RADVISION is in the advantageous position of offering one of the
most complete sets of Ensemble Development toolkits. RADVISION sells the core
enabling technology for real-time IP and 3G-based communication in the form of
software development kits. Communication equipment providers and developers
seeking to create and market industry standard compliant IP telephony and
multimedia products, systems and applications need core IP communication
protocol software to develop their IP-centric solutions. The same holds true for
developers of 3G-based multimedia solutions. Rather than dedicate in-house
resources to developing this core technology, these providers seek to build upon
RADVISION's proven enabling technologies.

RADVISION toolkits enable customers to focus on their core competencies and
dramatically reduce the time to market of industry standard compliant IP
communication products, systems and applications.

RADVISION SIP Development Toolkit

SIP is a relatively new signaling protocol for initiating, managing and
terminating voice and video sessions across packet networks. SIP was designed,
from conception, for building high performance user agents. The "SIP toolkit"
enables the development of products that require full user/agent functionality.
The SIP Toolkit is designed to provide high scalability and extensibility for
both small and large-scale projects. It enables the implementation of all types
of feature rich SIP entities such as application servers, softswitches, IP-PBXs,
gateways and conferencing bridges. RADVISION has developed a SIP Server toolkit
to target the specific needs of customers developing infra-structure devices
based on the SIP protocol.

RADVISION H.323 Development Toolkit

H.323 is currently the most widely deployed standard for real-time IP
communication. All components of an H.323-compliant network, including
terminals, gateways, gatekeepers and conferencing bridges, use the H.323
protocol to communicate. RADVISION's H.323 software development kits provide
developers with the core software building blocks needed to develop
H.323-compliant products, systems and applications. The RADVISION H.323 software
development kit is an integrated set of software programs that execute the H.323
protocol and perform the functions necessary to establish and maintain real-time
voice, video and data communication over packet-based networks. The RADVISION
H.323 software development kits can be used to develop a broad spectrum of
products, including gateways, gatekeepers, conferencing bridges, IP telephones
and other H.323-compliant products.

RADVISION MGCP Development Toolkit

Media gateway control protocol, commonly referred to as MGCP, provides
functions that complement H.323 and has been developed for large packet networks
operated by telecommunication carriers and service providers that require
gateways that can support a high number of calls. MGCP is the protocol by which
a centralized gateway controller communicates with and controls the numerous
gateways throughout a packet network and manages the network traffic through
those gateways. MGCP has been adopted by large telecommunication companies and
Internet service providers as well as by cable television companies building IP
communication solutions over their networks. The RADVISION MGCP software
development kit is used to build MGCP compliant media gateways controllers and
media gateways.

RADVISION MEGACO Development Toolkit

MEGACO/H.248 is the official industry standard media gateway control
protocol for large-scale IP-centric communication networks. Like MGCP, it is an
internal protocol used between "intelligent" centralized gateway controllers and
numerous "dumb" media gateways that handle voice and video media streams. The
standard is the result of a unique collaborative effort between the IETF and ITU
standards organizations. Derived from MGCP, MEGACO/H.248 offers several key
enhancements including support for multimedia and conferencing calls,

improved handling of protocol messages and a formal process for creating
extensions to support advanced functionality. RADVISION's MEGACO/H.248 Toolkit
includes a unique Media Device Manager to greatly simplify application
development and reduce development time by eliminating the need for developers
to write code for interpreting MEGACO/H.248 messages.

3G-324M Developer Toolkit

There is a newly approved standard, called 3G-324M, which supports the
real-time streaming of multimedia broadband wireless communication over 3G by
routing traffic over the circuit switched network. Because it is
circuit-switched based, the standard is well suited for streaming real-time
multimedia. 3G-324M enables the development, deployment and support of a wide
variety of delay-sensitive applications immediately. These include multimedia
conferencing with other 3G mobile end points and wire lined H.323 or SIP
terminals, video streaming, cell phone TV, video-on-demand (news, sports, etc.),
and multimedia, multi-participant gaming, to name a few. RADVISION was one of
the first companies to introduce a toolkit for the development of 3G-324M-based
products.

IP Phone Toolkit

RADVISION recently introduced a product for the manufacture of IP
Phones. The toolkit bundles TBU toolkits along with call control and endpoint
management software to provide an IP Phone application for any IP protocol (such
as H.323 and SIP). RADVISION is working with key silicon manufacturers in the
industry, including Texas Instruments, to provide pre-integrated packages
including the IP Phone Toolkit running on the OEM's chipset platform.

RADVISION ProLab Test Manager

RADVISION's ProLab is designed for debugging and simulating numerous
testing scenarios. Based on RADVISION's award-winning SIP and H.323 Protocol
Toolkit, this testing tool simulates a full VoIP network with a professional
quality assurance laboratory, enabling developers or QA specialists to test SIP
and H.323 version compliance, version upgrade compliance, stress and load. The
ProLab(TM) Test Manager is a highly scalable tool designed to be aware of any
changes to the SIP and H.323 standards. It provides the:

o capability to run the same tests on the application each time the
underlying protocol version is upgraded;

o flexibility to mix and match scenarios to develop a broad range of
testing possibilities; and

o ability to define numerous scripts and scale up the test scenario by
linking them as the test plan progresses.

TBU Product Benefits

Market Leading Technology for Standards - Based Real-time IP
Communication. We were one of the original five members of the ITU-T committee
responsible for defining the H.323 standard, which has been adopted worldwide
for real-time packet-based communication. We believe our technology is
recognized as the market-leading implementation of the H.323 industry standard
for real-time voice, video and data communication over packet networks. We also
believe that our technology is recognized as one of the market-leading
implementations of the Session Initiation Protocol, or SIP, and other protocols
such as MGCP and MEGACO/ H.248. We have been actively involved in the
development of protocols for real-time communication since the inception of the
industry in 1994 and believe that we were the first-to-market with enabling
products and technology for voice, video and data communication over IP
networks. We continue to be actively involved in the specification of evolving
IP communication protocols and offer a complete suite of IP communication
software toolkits to developers of IP-centric products, applications and
services. We believe that our technology has become the technology of choice
among developers of standards-compliant IP communication systems. Because we
believe we were first to market and have achieved broad market penetration, our
customers benefit from our ability to develop and provide them market-tested,
proven products and technology. Using our products and technology, our customers
can develop unique capabilities with increased functionality that will
differentiate their IP communication solutions in the market. We believe that
the accumulated knowledge that we have gained participating in the development
of industry standards provides us with a competitive advantage, and positions us
to be among the first to market products and technology based on the latest
technological advances.

Interoperability. We provide our customers with products and technology
that are interoperable across a broad range of IP communication systems. Our
products and technology have been integrated into IP communication systems
developed by hundreds of communication equipment providers. Because our products
and technology are broadly deployed across various segments of the IP
communication industry, we believe that the interoperability of our products and
technology with products from different vendors is virtually assured. We believe
that our long-standing involvement in the definition of standards and
accumulated experience with product development across our broad customer base
provides us with a competitive advantage in addressing interoperability needs.
We continue to participate actively in defining industry standards by working
closely with industry consortia on a broad spectrum of IP communication

protocols to ensure continued interoperability of our products and technology

Real-time Voice, Video and Data Communication Functionality. We are one
of the few companies that offer IP communication products which support both
voice-only, as well as combined voice, video and data communication. We believe
that this dual functionality is attractive to enterprises and service providers
that seek a flexible IP communication solution, which can provide enhanced
multimedia functionality in addition to IP telephony capabilities. We believe
our products enable developers of IP communication solutions to offer features
and functions generally unavailable in competitive solutions.

Improved Time to Market. Our customers rely on our accumulated expertise
with communication standards and core technology to significantly reduce their
development cycle and improve time to market. Communication equipment providers
seeking to market standards-compliant systems for real-time voice and video

our customers with flexibility to design individual products and applications or
complete systems. Our customers can build a complete network solution for
real-time IP communication using our full suite of products or integrate
RADVISION products with their own products or other vendor products into their
real-time IP communication solution. Similarly, our technology has been designed
to enable the development of a broad range of products and applications, from
those that can service single users, including hand held devices and residential
IP phones, to multi-user products, like highly complex, powerful carrier class
gateways. Taken together, our products and technology provide all of the key
network components necessary to build a real-time IP communication solutions.

Industry Trends That Benefit RADVISION's Developer Toolkits:

Growth in Communication

In the 1990's communication networks experienced dramatic growth in
traffic. After a decline in growth in the last three years due to what we
perceive as an industry trend, we believe this growth will resume within a few
years due to a number of factors, including:

o an increasing need for enterprises to expand their networks to enable
them to send, access and receive information quickly, economically and
globally;

o an increasing use of the Internet and other packet networks for
communicating and engaging in commercial transactions;

o an increase in available bandwidth at declining prices; and

o the introduction of new voice, video and data communication services
and applications.

Limitations of Traditional Networks

Traditionally, circuit-switched networks have been the principal medium
for the transmission of communication. Circuit-switched technology dedicates a
circuit with a fixed amount of bandwidth for the duration of the connection,
regardless of a user's actual bandwidth usage. The growth in data communication
traffic, particularly the growth in the number of Internet users, has placed
significant strains on the capacity of traditional circuit-switched networks.
Circuit-switched networks were initially deployed to handle only voice
communication. These networks were not designed to handle data efficiently and
cannot scale cost-effectively to accommodate the growth in data traffic.
Moreover, circuit-switched networks were built based on proprietary, complex
technologies, which have historically limited the entrance of new competitors
and hindered the development and introduction of new services.

Advantages of Packet-based Networks

While circuit-switched networks were principally designed to handle
analog voice traffic, packet-based networks were principally designed for
transmitting digital information. Packet-based networks, including IP networks,
transmit voice, video and data information in the form of small digital packages
called packets. Voice, video and data packets are sent over a single network
simultaneously and reassembled at the destination. Packet switching enables more
efficient utilization of available network bandwidth than circuit-switching,
allowing more calls to travel through a packet network at the same time.
Moreover, packet networks allow for the cost-efficient expansion of capacity as
communication traffic increases. In addition, packet networks are built using
open standards, like IP, which promote competition by allowing different vendors
to build products and applications that can interoperate with one another. By
using packet technologies based on open standards, new services can be deployed
rapidly and economically.

The Need for Products that Deliver Industry Standards for Real-time IP
Communication

Originally, enterprises and communication service providers deployed
packet networks primarily for handling data traffic and not for real-time IP
communication. Technical barriers initially hampered the use of packet networks
for real-time communication. For example, packet networks were not designed to
guarantee the sequential delivery of packets and packets could be lost. In
addition, the time of delivery of packets was dependent upon the amount of
packet traffic being transmitted over the network. For real-time communication,
it is critical that the packets associated with a specific voice or video
communication be transmitted in the correct sequence and in a timely manner.
Early attempts at real-time IP communication solved these technical problems by
using proprietary solutions developed by individual vendors. However,
proprietary

solutions from different vendors meant that different vendor products could not
interoperate with one another.

To enable the global deployment of real-time IP communication networks,
industry standards and protocols were developed to promote interoperability of
real-time communication over packet networks. H.323 is currently the most widely
deployed protocol for real-time IP communication. H.323 was developed by a team
of computing, telephony and networking experts under the auspices of the
International Telecommunication Union, or ITU-T, a United Nations organization,
with the goal of specifying a universal real-time standard that would ensure
interoperability of rich-media communication on packet-based networks. H.323
provides the technical framework for developing standards-compliant products and
systems for real-time voice and video communication over packet networks. All
components of an H.323 compliant network, including terminals, gateways,
gatekeepers and conferencing bridges, use the H.323 protocol to communicate.

Additionally, many companies are beginning to develop SIP-based
products. RADVISION is one of the leading vendors in this space, providing
solutions for the development of SIP phones and devices, SIP servers and
registrars, IP-PBX's and a wide variety of other SIP-based communication
devices.

Our leadership position stems from the pioneering work we began in 1993.
We were the first to develop and demonstrate commercially viable technology for
establishing real-time voice, video, and data on IP networks. Since our
inception, we have been helping to develop the industry standards that are
driving the emergence and growth of the use of packet networks for real-time
communication. RADVISION was an original member of the ITU (International
Telecommunication Union) team that defined the H.323 standard, and we continue
to work closely with the ITU, the IETF, IMTC, and other industry consortia to
define a broad spectrum of IP telephony protocols for voice and video
communication including, Session Initiation Protocol (SIP), Media Gateway
Control Protocol (MGCP) and MEGACO/H.248.

Our protocol toolkits provide the underpinning technology required for
the rapid development of next generation products and applications for real-time
VoIP. Industry giants and emerging technology companies use our family of IP
communication protocol toolkits to reduce their time to market for developing
interoperable, standards-compliant V2oIP products, applications and services.
Today you will find RADVISION protocols implemented in a wide range of
environments from chipsets to simple user devices like IP phones and video
systems through carrier class network devices like gateways, switches and
softswitches.

Growth in Real-time Voice and Video IP Communication

Due to the inherent benefits of packet networks and the advent of new
technologies and standards that have enabled real-time communication over these
networks, the use of packet networks for real-time voice, video and data
communication is expected to grow dramatically. This anticipated growth in
real-time IP communication is expected to be driven primarily by enterprises and
communication service providers migrating to packet networks. As enterprises
move from centralized organizations to distributed networks of employees,
customers, suppliers and business partners, they require more effective
communication capabilities to support their

operations and remain competitive in a global and rapidly changing market.
Packet networks are well suited for enterprises because they provide enterprises
with the following advantages:

o cost-effective increases in capacity to meet increasing communication
traffic demands;

o support for new communication applications, like video conferencing
and data collaboration, for improved workforce productivity;

o interoperability with different network configurations of their
customers, suppliers and partners; and

o cost savings associated with simplified network management resulting
from creating a single network that handles all communication, rather
than having to maintain separate telephone and computer networks.

Communication service providers have also begun to deploy packet
networks in an effort to compete more effectively in a deregulated market.
Global deregulation and rapid technological advances have resulted in the
emergence of many new communication service providers, increased competition
among traditional telecommunication carriers, lower prices, innovative new
product and service offerings and accelerated customer turnover. To remain
competitive, communication service providers must be able to develop and
introduce new services to differentiate themselves in the market and attract and
maintain customers. Packet networks are well suited to accomplish these
objectives because they enable the rapid deployment of new and differentiated
solutions. In addition, packet-based technology allows new competitors to enter
the market quickly without substantial investment in infrastructure.

Broadband Wireless

There has been a tremendous rush to acquire and roll out 3G broadband
wireless services in key markets. While these efforts have slowed significantly
in North America, Asia has already rolled out its first WCDMA network and Europe
is close behind.

Both 3G standards bodies, 3GPP and 3GPP2, envision 3G as running
entirely over an IP-based communication network (the Internet). However, the
prevailing business environment has pushed this vision out by quite a few years.
The current telecom downturn may further extend the length of time until 3G is
entirely IP-based.

The main problem is that today's IP network (the Internet) is not
sufficiently robust for delay sensitive applications and, in fact, will not be
so until service providers move to IPv6 and SIP-based IP communication. IP, with
its variant transmission delays (many hops routing and congestion effects) and
packet overheads, is ill equipped at this time to provide high quality, real
time multimedia delivery over 3G (WCDMA and CDMA2000) networks.

While the vision of a true IP-based 3G network has been delayed, the
promise of a feature-rich, multimedia wireless experience has not. This is due
to the emergence of a standard, called 3G-324M, which addresses and supports the
real-time streaming of multimedia broadband wireless communication by routing
traffic over the circuit switched network. Being circuit-switched based, the
standard has all the hallmarks of a protocol ideal for streaming real-time

multimedia, including a fixed delay, low overhead of CODECS, and no IP/UDP/RTP
header overheads.

3G-324M, based on ITU H.324M and specified in detail by 3GPP (3GPP TS
26.112 and 3GPP TS 26.111 Working Groups), enables the development, deployment
and support of a wide variety of delay-sensitive applications immediately.
Enabled applications include multimedia conferencing with other 3G mobile end
points, and wire lined H.323 or SIP terminals, video streaming, cell phone TV,
video-on-demand (news, sports, etc.) and multimedia, multi-participant gaming.

RADVISION has taken a pioneering role in providing 3G-324 developer
toolkits that enable equipment developers to develop products, ranging from 3G
handsets to gateways and media servers, that will deliver real time multimedia
services over 3G.

Customer Care and Support

Our ability to provide our customers with responsive and qualified
customer care and support services globally is essential to attract and retain
customers, build brand loyalty and maintain our leadership position in the
market. We believe our customer care and support organizational structure
enables us to provide superior technical support and customer service on a cost-
and time-efficient basis.

We provide global customer care and support for our products and
technology. Our customer care and technical support teams are located in Tel
Aviv, Israel, Glen Rock, New Jersey, Sunnyvale, California, Hong Kong and China
and recently went to a 24x7x365 support timeline to better serve our networking
customers who desire the expanded service. We assist our networking customers
with the initial installation, set-up and training. In addition, our technical
support team trains and certifies our networking customers to provide local
support in each of the geographical areas in which our products are sold. In
2003, we developed and rolled out a customer support model where service
contracts are mandatory for each new customer.

In addition, customers who purchase our TBU software development kits
generally request that we provide them with ongoing engineering and technical
support services to

integrate our technology into their products, although these services are not
essential for the use of our software development kits. Our standard software
development kit contract provides for one year of support services, renewable
annually at the customer's option. Customers who have contracted for support
services receive all relevant software updates and enhancements as well as
access to our customer care and technical support teams.

Additionally, in 2003, we launched our Professional Services Division,
which provides development expertise to our TBU customers that might require not
only our developer solutions/toolkits but also our deep protocol experience and
development skill. In this case we work hand-in-hand with the customer
throughout the entire process, providing a full range of consulting, engineering
and software development services to support our customers in bringing
innovative voice and video products to market on time using the RADVISION
Ensemble suite of developer toolkits and RADVISION's protocol and development
expertise. The Professional Services team handles the complete project
life-cycle from design, throughout the product development, and even on-site
deployment

Intellectual Property

We rely on copyright, trademark and trade secret laws, confidentiality
agreements and other contractual arrangements with our customers, third-party
distributors, employees and others to protect our intellectual property.

Despite our efforts to protect our proprietary rights, unauthorized
parties may attempt to copy aspects of our products and technology or obtain and
use information that we regard as proprietary. Policing unauthorized use of our
products and technology is difficult. In addition, the laws of some foreign
countries in which we currently or may in the future sell products do not
protect our proprietary rights to as great an extent as do the laws of the
United States. Our means of protecting our proprietary rights may not be
adequate and our competitors may independently develop similar technology,
duplicate our products or design around our intellectual property.

We rely on certain technology that we license from third parties,
including software that is integrated with internally developed software and
used in our products to perform key functions. For example, we license T.120
data collaboration software from Data Connection Limited and voice compression
technology from Siemens. If we are unable to continue to license any of this
software on commercially reasonable terms, we will face delays in releases of
our products or will be required to reduce the functionality of our products
until equivalent technology can be identified, licensed or developed, and
integrated into our current products.

Research and Development

We place considerable emphasis on research and development to expand the
capabilities of our existing products and technology, to develop new products
and to improve our existing technologies and capabilities. We believe that our
future success will depend upon our ability to maintain our technological
leadership, to enhance our existing products and technology and to introduce on
a timely basis new commercially viable products and technology addressing the
needs of our customers. Our gross investment in research and development for the
years ended

December 31, 2001, 2002 and 2003 was $17.9 million, $15.3 million and $14.6
million, respectively. We intend to continue to devote a significant portion of
our personnel and financial resources to research and development. As part of
our product development process, we seek to maintain close relationships with
our customers to identify market needs and to define appropriate product
specifications.

As of December 31, 2003, our research and development staff consisted of
approximately 114 employees. Our research and development activities are
conducted at our facilities in Tel Aviv, Israel. To introduce new, high quality
products, we deploy procedures for the design, development and quality assurance
of our new product developments. Our team is divided according to our existing
product lines. Each product line team is headed by a team leader and includes
software or hardware engineers and quality control technicians.

Competition

We compete in a new, rapidly evolving and highly competitive and
fragmented market. We expect competition to intensify in the future. We believe
that the main competitive factors in our market are time to market, product
quality, features, cost, technological performance, scalability, compliance with
industry standards and customer relationships.

The principal competitors in the market for our products and software
development kits currently include:

Networking Products Software development kits
-------------------------------------- -------------------------------

o DynamicSoft Inc.
o Polycom Networks, a division
of Polycom Inc., which was o Trillium Digital Systems,
formerly known as Accord Networks acquired by Continuous
Computing.
o Tandberg
o Hughes Software Systems
o CUseeMe Networks Inc. (formerly
known as White Pine Software Inc., o DCL
which merged with First Virtual
Communication) o Dylithium

In the 3G market: o In-house developers
o Erickson employed by manufacturers
o Dylithium of telecommunication
equipment and systems

Additional competitors may enter any of our markets at any time.

Both Vovida Networks (now part of Cisco Systems, Inc.) and OpenH323
offer H.323 source code for free. In addition, Vovida offers MGCP and SIP source
code for free. If our customers choose to use the free source code offered by
these organizations instead of

purchasing our technology, our revenues from the sale of our software
development kits will decline.

Manufacturing

Our manufacturing operations consist of materials planning and
procurement, out-sourcing of sub-assemblies, final assembly, product assurance
testing, quality control and packaging and shipping. We assemble our products in
a subcontractor's facilities in Israel and test our products at our facilities
in Tel Aviv, Israel. We test our products both during and after the assembly
process using internally developed product assurance testing procedures. We have
a flexible assembly process that enables us to configure our products at the
final assembly stage for customers who require that our products be modified to
bear their private label. This flexibility is designed to reduce our assembly
cycle time and reduce our need to maintain a large inventory of finished goods.
We use an enterprise resource planning, or ERP, system that we purchased from
BAAN Systems that we modified to our specific needs. This system allows us to
use just in time procurement and manufacturing procedures. We believe that the
efficiency of our assembly process to date is largely due to our product
architecture and our commitment to assembly process design. We manufacture our
software development kits on CD-ROMs and package and ship them accompanied by
relevant documentation.

As part of our commitment to quality, we have been certified as an ISO
9002 supplier. The ISO 9002 standard defines the procedures required for the
manufacture of products with predictable and stable performance and quality. We
are continuously trying to improve our quality based on the guidelines dictated
by the ISO 9002 standard.

Employees

As of December 31, 2003, we had 258 employees worldwide, of whom 114
were employed in research and development, 94 in sales and marketing, 30 in
management and administration and 20 in operations. We have standard employment
agreements with all of our employees located in Israel. Of our employees, 180
are based in Israel, 52 are based in the United States, 19 are based in Hong
Kong and China and 7 are based in the United Kingdom.

Our relationships with our employees in Israel are governed by Israeli
labor legislation and regulations, extension orders of the Israeli Ministry of
Labor and Welfare and personal employment agreements. Israeli labor laws and
regulations are applicable to all of our employees in Israel. The laws concern
various matters, including severance pay rights at termination, notice period
for termination, retirement or death, length of workday and workweek, minimum
wage, overtime payments and insurance for work-related accidents. We currently
fund our ongoing legal severance pay obligations by paying monthly premiums for
our employees' insurance policies.

In addition, Israeli law requires Israeli employees and employers to pay
specified sums to the National Insurance Institute, which is similar to the
United States Social Security Administration. Since January 1, 1995, such
amounts also include payments for national health insurance. The payments to the
National Insurance Institute that include health insurance fees are
approximately 14.5% of wages, of which the employee contributes approximately
66.0% and the

employer contributes approximately 34.0%. The majority of our permanent
employees are covered by life and pension insurance policies providing customary
benefits to employees, including retirement and severance benefits. We
contribute 13.3% to 15.8%, depending on the employee, of base wages to such
plans and the employee contributes 5.0%. RADVISION and its employees are not
parties to any collective bargaining agreements. However, certain provisions of
the collective bargaining agreements between the Histadrut, the General
Federation of Labor in Israel, and the Coordination Bureau of Economic
Organizations, including the Manufacturers' Association of Israel, are
applicable to our employees by "extension orders" of the Israeli Ministry of
Labor and Welfare. These provisions principally concern periodic cost of living
adjustments, procedures for dismissing employees, travel allowances,
recuperation pay and other conditions of employment.

At the start of their employment, our employees in North America
generally sign offer letters specifying basic terms and conditions of employment
as well as non-disclosure agreements. At the start of their employment, our
employees in Israel generally sign written employment agreements that include
confidentiality and non-compete provisions.

RISK FACTORS

Investing in our ordinary shares involves a high degree of risk and
uncertainty. You should carefully consider the risks and uncertainties described
below before investing in our ordinary shares. If any of the following risks
actually occurs, our business, prospects, financial condition and results of
operations could be harmed. In that case, the value of our ordinary shares could
decline, and you could lose all or part of your investment.

Risks Relating to Our Business

Until 2001, we had a history of losses and we cannot assure you that we will
continue to operate profitably in the future.

Although we operated profitably in 2003 we cannot assure you that we
will continue to operate profitably in the future. We incurred significant
losses in every fiscal year from our inception until 1999, and we incurred
operating losses in 2000 and 2001. As of December 31, 2003, our accumulated
deficit was $6.5 million.

Our quarterly financial performance is likely to vary significantly in the
future. Our revenues and operating results in any quarter may not be indicative
of our future performance and it may be difficult for investors to evaluate our
prospects.

Our quarterly revenues and operating results have varied significantly
in the past and are likely to continue to vary significantly in the future.
Fluctuations in our quarterly financial performance may result from the fact
that we may receive a small number of relatively large orders in any given
quarter. Because these orders generate disproportionately large revenues, our
revenues and the rate of growth of our revenues for that quarter may reach
levels that may not be sustained in subsequent quarters. In addition, some of
our products have lengthy sales cycles. For example, it typically takes from
three to twelve months after we first begin discussions with a prospective
customer before we receive an order from that customer. We also have a limited
order backlog, which makes revenues in any quarter substantially dependent upon
orders we deliver in that quarter. Because of these factors, our revenues and
operating results in any quarter may not meet market expectations or be
indicative of future performance and it may be difficult for investors to
evaluate our prospects.

Unless our revenues grow in excess of our increasing expenses, we will not be
profitable.

We expect that our operating expenses will increase significantly in the
future, both to finance the planned expansion of our sales and marketing and
research and development activities and to fund the anticipated growth in our
revenues. However, our revenues may not grow apace or even continue at their
current level. If our revenues do not increase as anticipated or if expenses
increase at a greater pace than our revenues, we will not be profitable. Even if
we achieve profitability, we may not be able to sustain or increase
profitability on a quarterly or annual basis.

If the use of packet-based networks as a medium for real-time voice, video and
data communication does not continue to grow, the demand for our products and
technology will slow and our revenues will decline.

Our future success depends on the growth in the use of packet-based
networks, including the Internet and other IP networks, as a medium for
real-time voice, video and data communication. If the use of packet-based
networks does not expand, the demand for our products and technology will slow
and our revenues will decline. Market acceptance of packet-based networks as a
viable alternative to circuit-switched networks for the transmission of
real-time voice and video communication is not proven and may be inhibited by
concerns about quality of service and potentially inadequate development of the
necessary infrastructure.

We must develop new products and technology and enhancements to existing
products and technology to remain competitive. If we fail to do so, we may lose
market share to our competitors and our revenues may decline.

The market for our products and technology is characterized by rapid
technological change, new and improved product introductions, changes in
customer requirements and evolving industry standards. Our future success will
depend to a substantial extent on our ability to:

o timely identify new market trends; and

o develop, introduce and support new and enhanced products and
technology on a successful and timely basis.

If we fail to develop and deploy new products and technology or product
and technology enhancements on a successful and timely basis, we may lose market
share to our competitors and our revenues may decline.

We are currently developing new products and technology and enhancements
to our existing products and technology. We may not be successful in developing
or introducing these or any other new products or technology to the market.

We have invested, and will continue to invest, in products and technology that
comply with those industry standards that we believe have been, or will be,
broadly adopted. If one or more alternative standards were to gain greater
acceptance than the standards that we believe have or will be broadly adopted,
sales of our products and technology might suffer.

Currently, we offer networking products that comply with the H.323
industry standard for real-time voice, video and data communication over packet
networks. During 2000, we expanded our enabling technology product family to
include additional key IP protocols. Our current suite of IP communication
protocol toolkits include H.323, SIP, MGCP, MEGACO and H.324M. We believe that
IP networks will be designed with components built around each of these
protocols. If these expectations ultimately prove to be incorrect, our
investments may be of little or no value.

We rely on a small number of marketing partners who distribute our products
either under our name or as private label products for a significant portion of
our business.

We rely in great measure on OEMs, systems integrators and value added
resellers, or VARs, to sell our products. Our OEM customers purchase our
products to integrate with products that they developed in-house to build
complete IP communication solutions. Our systems integrator customers either
purchase our full suite of products or integrate our individual products of
other manufacturers to build complete IP communication solutions. Our VAR
customers purchase our products to resell to end-users as separate units, or as
part of a family of related product offerings, either under our RADVISION label
or under their private label. If we are unable to maintain these marketing
partners or obtain new marketing partners, our future revenues and profitability
will be affected and we may lose market share.

Competition in the markets for our products and technology is intense. We may
not be able to compete effectively in these markets and we may lose market share
to our competitors.

The markets for our products and technology are highly competitive and
we expect competition to intensify in the future. We may not be able to compete
effectively in these markets and we may lose market share to our competitors.
The principal competitors in the market for our NBU products currently include
Polycom Inc., which acquired Accord Networks Inc., First Virtual Communication,
which merged with CUseeMe Networks Inc. (formerly known as White Pine Software
Inc.). The principal competitors in the market for our TBU products currently
include Hughes Software Systems, DynamicSoft, Dylithium, and in-house developers
employed by manufacturers of telecommunication equipment and systems. Additional
competitors may enter each of our markets at any time. Moreover, our customers
may seek to develop internally the products that we currently sell to them and
compete with us.

Major solutions providers who currently work with us might compete with us in
the future.

We currently provide our technology to major solutions providers
including Cisco, Siemens, Microsoft and Tanldberg. If these providers choose to
develop their own technologies, acquire technologies from our competitors, or
acquire such competitors, our financial condition and operating results could be
adversely impacted and we may face increased levels of competition from these
major companies.

Our software development kit revenues will decrease if our customers choose to
use source code that is available for free.

Both Vovida Networks, Inc. (part of Cisco Systems Inc.) and OpenH323
offer H.323 source code for free. In addition, Vovida offers MGCP and SIP source
code for free. If our customers choose to use the free source code offered by
these organizations instead of purchasing our technology, our revenues from the
sale of our software development kits will decline. Other companies, including
Microsoft, may offer similar development kits as part of their product
offerings.

Most of our competitors have greater resources than we do. This may limit our
ability to compete effectively with them and discourage customers from
purchasing our products and technology.

Most of our competitors have greater financial, personnel and other
resources than we do, which may limit our ability to compete effectively with
them. These competitors may be able to respond more quickly to new or emerging
technologies or changes in customer requirements. These competitors may also:

o benefit from greater economies of scale;

o offer more aggressive pricing; or

o devote greater resources to the promotion of their products.

Any of these advantages may discourage customers from purchasing our
products and technology. If we are unable to compete successfully against our
existing or potential competitors, our revenues and margins will decline.

Our agreements with our customers generally do not have minimum purchase
requirements. If our customers decrease or cease purchasing our products and
technology, our revenues will decline.

Our agreements with our customers generally do not have minimum purchase
requirements nor do they require our customers to purchase any products from us.
If any or all of our customers cease to purchase or reduce their purchases of
our products and technology at any time, our revenues will decline. We cannot
assure you that our customers will not choose to independently develop for
themselves, or purchase from others, products and technology similar to our
products and technology. Moreover, if our customers do not successfully market
and sell the systems and products into which they incorporate our products and
technology, the demand of these customers for our products and technology will
decline. Our customers' sales of systems and products containing our products
and technology may be adversely affected by circumstances over which we have no
control and over which our customers may have little, if any, control.

We are dependent upon a limited number of suppliers of key components. If these
suppliers delay or discontinue manufacture of these components, we may
experience delays in shipments, increased costs and cancellation of orders for
our products.

We currently obtain key components used in the manufacture of our
products from a single supplier or from a limited number of suppliers. We do not
have long-term supply contracts with our suppliers. Any delays in delivery of or
shortages in these components could interrupt and delay manufacturing of our
products and result in the cancellation of orders for our products. In addition,
these suppliers could discontinue the manufacture or supply of these components
at any time. We may not be able to identify and integrate alternative sources of
supply in a timely fashion or at all. Any transition to alternate suppliers may
result in delays in shipment and increased expenses and may limit our ability to
deliver products to our customers. Furthermore,

if we are unable to identify an alternative source of supply, we would have to
modify our products to use a substitute component, which may cause delays in
shipments, increased design and manufacturing costs and increased prices for our
products.

We intend to manufacture and maintain an inventory of customized products for
some customers who will have no obligation to purchase these products. If these
customers fail to purchase these products, our financial results may be harmed.

To satisfy the timing requirements of some of our larger customers, we
intend to manufacture and maintain an inventory of some of our products that we
will customize to the specifications of these customers. The size of this
inventory will be based upon the purchasing history and forecasts of these
customers, which we currently estimate to be approximately two months of sales
to these customers. These customers will have no obligation to purchase the
inventoried products at any time. If the customers for whom the inventoried
products are manufactured do not purchase them, we may be required to modify the
products for sale to others and we may be unable to find other purchasers. In
either case, the value of the products may be materially diminished which may
have a negative impact on our financial results.

Undetected errors may increase our costs and impair the market acceptance of our
products and technology.

Our products and technology have occasionally contained, and may in the
future contain, undetected errors when first introduced or when new versions are
released. Our customers integrate our products and technology into systems and
products that they develop themselves or acquire from other vendors. As a
result, when problems occur in equipment or a system into which our products or
technology have been incorporated, it may be difficult to identify the cause of
the problem. Regardless of the source of these errors, we must divert the
attention of our engineering personnel from our research and development efforts
to address the errors. We cannot assure you that we will not incur warranty or
repair costs, be subject to liability claims for damages related to product
errors or experience delays as a result of these errors in the future. Any
insurance policies that we may have, may not provide sufficient protection or
coverage should a claim be asserted. Moreover, the occurrence of errors, whether
caused by our products or technology or the products of another vendor, may
result in significant customer relations problems and injury to our reputation
and may impair the market acceptance of our products and technology.

We rely on third party technology licenses. If we are unable to continue to
license this technology on reasonable terms, we may face delays in releases of
our products and may be required to reduce the functionality of our products
derived from this technology.

We rely on technology that we license from third parties, including
software that is integrated with internally developed software and used in our
products to perform key functions. For example, we license T.120 data
collaboration software from Data Connection Limited and voice compression
technology from Siemens. If we are unable to continue to license any of this
software on commercially reasonable terms, we will face delays in releases of
our products or will be required to reduce the functionality of our products
until equivalent technology can be identified, licensed or developed, and
integrated into our current products.

Third parties may infringe upon or misappropriate our intellectual property,
which could impair our ability to compete effectively and negatively affect our
profitability.

Our success depends upon the protection of our technology, trade secrets
and trademarks. Our profitability could suffer if third parties infringe upon
our intellectual property rights or misappropriate our technology and other
assets or the intellectual property rights licensed from third parties. To
protect our rights to our intellectual property, we rely on a combination of
trade secret protection, trademark law, confidentiality agreements and other
contractual arrangements. We rely on third parties to protect their intellectual
property which is licensed to us, but we do not generally investigate to what
extent such intellectual property is protected. The protective steps we have
taken may be inadequate to deter infringement or misappropriation. We may be
unable to detect the unauthorized use of our intellectual property or take
appropriate steps to enforce our intellectual property rights. Policing
unauthorized use of our products and technology is difficult. In addition, the
laws of some foreign countries in which we currently or may in the future sell
our products do not protect our proprietary rights to as great an extent as do
the laws of the United States. Failure to adequately protect or to promptly
detect unauthorized use of our intellectual property could devalue our
proprietary content and impair our ability to compete effectively. Further,
defending our intellectual property rights could result in the expenditure of
significant financial and managerial resources, whether or not the defense is
successful.

Our products may infringe on the intellectual property rights of others, which
could increase our costs and negatively affect our profitability.

Third parties may assert against us infringement claims or claims that
we have infringed a patent, copyright, trademark or other proprietary right
belonging to them. For example, in 1998, Lucent alleged that some products
manufactured by us infringed specified Lucent patents. See "Item 3. Legal
Proceedings." Any infringement claim, even if not meritorious, could result in
the expenditure of significant financial and managerial resources and could
negatively affect our profitability.

We are dependent on our senior management. Any loss of the services of our
senior management could negatively affect our business.

Our future success depends to a large extent on the continued services
of our senior management and key personnel. We do not carry key-man life
insurance for any of our senior management. Any loss of the services of members
of our senior management or other key personnel could negatively affect our
business.

Our failure to retain and attract personnel could harm our business, operations
and product development efforts.

Our products require sophisticated research and development, marketing
and sales, and technical customer support. Our success depends on our ability to
attract, train and retain qualified research and development, marketing and
sales and technical customer support personnel. We intend to increase
substantially the number of our employees who perform these functions.
Competition for personnel in all of these areas is intense and we may not be
able to

hire sufficient personnel to achieve our goals or support the anticipated growth
in our business. The market for the highly-trained personnel we require is very
competitive, due to the limited number of people available with the necessary
technical skills and understanding of our products and technology. If we fail to
attract and retain qualified personnel, our business, operations and product
development efforts would suffer.

Our non-competition agreements with our employees may not be enforceable. If any
of these employees leaves us and joins a competitor, our competitor could
benefit from the expertise our former employee gained while working for us.

We currently have non-competition agreements with our key employees in
Israel. These agreements prohibit those employees, if they cease to work for us,
from directly competing with us or working for our competitors. Under current
U.S. and Israeli law, we may not be able to enforce these non-competition
agreements. If we are unable to enforce any of these agreements, our competitors
that employ our former employees could benefit from the expertise our former
employees gained while working for us. In addition, we do not have
non-competition agreements with our employees outside of Israel.

Government regulation could delay or prevent product offerings, resulting in
decreased revenues.

Our products are designed to operate with local telephone systems
throughout the world and therefore must comply with the regulations of the
Federal Communication Commission and other regulations affecting the
transmission of voice, video and data over telecommunication and other media.
Each time we introduce a new product, we are required to obtain regulatory
approval in the countries in which it is offered. In addition, we must
periodically obtain renewals of the regulatory approvals for the use of our
products in countries where we have already obtained approval. We cannot assure
you that regulatory approval for our current products will be renewed or that
regulatory approval for future products will be obtained. If we do not obtain
the necessary approvals and renewals, we may be required to delay the sales of
our products in those countries until approval for use is granted or renewed.
This could result in decreased revenues.

Risks Relating to Our Location in Israel

Conditions in Israel affect our operations and may limit our ability to produce
and sell our products, which could decrease our revenues.

We are incorporated under the laws of Israel, and most of our offices
and our production facilities are located in the State of Israel. As a result,
the political, economic and military conditions in Israel directly influence us.
Any major hostilities involving Israel or the interruption or curtailment of
trade between Israel and its present trading partners could have a material
adverse effect on our business, financial condition and results of operations.
Since the establishment of the State of Israel in 1948, a state of hostility has
existed, varying in degree and intensity, between Israel and the Arab countries
in the region. While Israel has entered into peace agreements with both Egypt
and Jordan and several other countries have announced their intentions to
establish trade and other relations with Israel, Israel has not entered into any

additional peace agreements with such countries or with Syria or Lebanon. Peace
talks between Israel and the Palestinian Authority began in the early 1990s, but
broke down in mid-2000. Attacks on Israel by Palestinian terrorists, and
military responses by Israel, have accelerated considerably since late 2000. The
continued hostilities between the Palestinian community and Israel and the
failure to settle the conflict has had and continues to have a material adverse
effect on the Israeli economy and may have a material adverse effect on our
business and us. Further expansion of hostilities might require more widespread
military reserve service by some of our employees, which may have a material
adverse effect on our business. We cannot predict whether or when the peace
process will resume, whether a full resolution of these problems will be
achieved, the nature of any such resolution or the consequences that any of
these factors may have on us.

The economic conditions in Israel have not been stable in recent years.

As a result of political instability, the increased level of hostilities
with the Palestinian Authority and the world-wide economic crisis in the
high-tech and communication industries, the Israeli rate of economic growth
deteriorated in 2001 and 2002, the Israeli currency was devalued and the rate of
inflation increased. The Israeli Government has proposed certain budgetary cuts
and other changes. Although with the assistance of the U.S. Government economic
stability was reached in 2003 and the rate of inflation was negative for the
first time in 2003 since the establishment of the State, we cannot assure you
that the Israeli Government will be successful in its attempts to stabilize the
Israeli economy or to maintain Israel's current credit rating. Should Israel's
credit rating decline, the ability of the Israeli government to generate foreign
financial and economic assistance may be adversely affected. Economic decline as
well as price and exchange rate instability may have a material adverse effect
on us.

Some of our directors, officers and employees are obligated to perform annual
military reserve duty in Israel. We cannot assess the potential impact of these
obligations on our business.

Our directors, officers and employees who are male adult citizens and
permanent residents of Israel under the age of 48 are, unless exempt, are
obligated to perform annual military reserve duty and are subject to being
called to active duty at any time under emergency circumstances. We cannot
assess the full impact of these requirements on our workforce or business if
conditions should change, and we cannot predict the effect on our business in
the event of an expansion or reduction of these obligations.

Because most of our revenues are generated in U.S. dollars or are linked to
the U.S. dollar while a portion of our expenses are incurred in new Israeli
shekels, our results of operations would be adversely affected if inflation in
Israel is not offset on a timely basis by a devaluation of the new Israeli
shekel against the U.S. dollar.

Most of our revenues are in dollars or are linked to the dollar, while a
portion of our expenses, principally salaries and the related personnel
expenses, are in new Israeli shekels, or NIS. As a result, we are exposed to the
risk that the rate of inflation in Israel will exceed the rate of devaluation of
the NIS in relation to the dollar or that the timing of this devaluation lags
behind inflation in Israel. This would have the effect of increasing the dollar
cost of our

operations. In 1999 and 2000 while the rate of inflation was low, there was a
devaluation of the dollar against the NIS. In the years 2001 and 2002 the rate
of devaluation of the NIS against the dollar exceeded the rate of inflation. In
2003 there was a devaluation of the dollar against the NIS. We cannot predict
any future trends in the rate of inflation in Israel or the rate of devaluation
of the NIS against the dollar. If the dollar cost of our operations in Israel
increases, our dollar-measured results of operations will be adversely affected.

The tax benefits that we currently receive from our approved enterprise programs
require us to satisfy specified conditions. If we fail to satisfy these
conditions, we may be required to pay additional taxes and would likely be
denied these benefits in the future.

The Investment Center of the Israeli Ministry of Industry and Trade has
granted approved enterprise status to several investment programs at our
manufacturing facility. The portion of our income derived from these approved
enterprise programs commencing when we begin to generate net income from these
programs will be exempt from tax for a period of two years and will be subject
to a reduced tax rate for an additional five to eight years, depending on the
percentage of our share capital held by non-Israelis. The benefits available to
an approved enterprise program are dependent upon the fulfillment of conditions
stipulated in applicable law and in the certificate of approval. If we fail to
comply with these conditions, in whole or in part, we may be required to pay
additional taxes during the period in which we would have benefited from the tax
exemption or reduced tax rates and would likely be denied these benefits in the
future.

It may be difficult to enforce a U.S. judgment against us and most of our
officers and directors or to assert U.S. securities laws claims in Israel or
serve process on most of our officers and directors.

We are incorporated in Israel. Many of our executive officers and
directors are nonresidents of the United States, and a substantial portion of
our assets and the assets of these persons are located outside the United
States. Therefore, it may be difficult for an investor, or any other person or
entity, to enforce a U.S. court judgment based upon the civil liability
provisions of the U.S. federal securities laws in an Israeli court against us or
any of those persons or to effect service of process upon these persons in the
United States. Additionally, it may be difficult for an investor, or any other
person or entity, to enforce civil liabilities under U.S. federal securities
laws in original actions instituted in Israel.

Risks Relating to Our Ordinary Shares

Holders of our ordinary shares who are United States residents face income tax
risks.

There is a risk that we will be classified as a passive foreign
investment company, or PFIC. Our treatment as a PFIC could result in a reduction
in the after-tax return to the holders of our ordinary shares and would likely
cause a reduction in the value of such shares. For U.S. Federal income tax
purposes, we will be classified as a PFIC for any taxable year in which either
(i) 75% or more of our gross income is passive income, or (ii) at least 50% of
the average value of all of our assets for the taxable year produce or are held
for the production of passive income. For this purpose, passive income includes
dividends, interest, royalties, rents, annuities and the

excess of gains over losses from the disposition of assets that produce passive
income. If we were determined to be a PFIC for U.S. federal income tax purposes,
highly complex rules would apply to U.S. Holders owning ordinary shares.
Accordingly, you are urged to consult your tax advisors regarding the
application of such rules.

As a result of our substantial cash position, if the value of our stock
declines, there is a substantial risk that we will be classified as a PFIC under
the asset test described in the preceding paragraph. Based on an independent
third party opinion, we believe that we were not deemed to be classified as a
PFIC in 2002, and as a result of the increase in the value of our stock, we
believe that we were not deemed to be classified as a PFIC in 2003. We have,
however, no assurance that the U.S. Internal Revenue Services will accept this
determination and there can be no assurance that we will not be classified as a
PFIC in the future.

United States residents should carefully read "Item 10E. Additional
Information - Taxation, United States Federal Income Tax Consequences" for a
more complete discussion of the U.S. federal income tax risks related to owning
and disposing of our ordinary shares.

Our share price has been volatile in the past and may decline in the future.

Our ordinary shares have experienced significant market price and volume
fluctuations in the past and may experience significant market price and volume
fluctuations in the future in response to factors such as the following, some of
which are beyond our control:

o quarterly variations in our operating results;

o operating results that vary from the expectations of securities
analysts and investors;

o changes in expectations as to our future financial performance,
including financial estimates by securities analysts and investors;

o announcements of technological innovations or new products by us or
our competitors;

o announcements by us or our competitors of significant contracts,
acquisitions, strategic partnerships, joint ventures or capital
commitments;

o changes in the status of our intellectual property rights;

o announcements by third parties of significant claims or proceedings
against us;

o additions or departures of key personnel;

o future sales of our ordinary shares; and

o stock market price and volume fluctuations.

Domestic and international stock markets often experience extreme price
and volume fluctuations. Market fluctuations, as well as general political and
economic conditions, such as a

recession or interest rate or currency rate fluctuations or political events or
hostilities in or surrounding Israel, could adversely affect the market price of
our ordinary shares.

In the past, securities class action litigation has been brought against
a company following periods of volatility in the market price of its securities.
We could potentially in the future be the target of similar litigation.
Securities litigation could result in substantial costs and divert management's
attention and resources.

Anti-takeover provisions could negatively impact our shareholders.

The new Israeli Companies Law provides that an acquisition of shares in
a public company must be made by means of a tender offer if as a result of the
acquisition the purchaser would become a 25% shareholder of the company. This
rule does not apply if there is already another 25% shareholder of the company.
Similarly, the Israeli Companies Law provides that an acquisition of shares in a
public company must be made by means of a tender offer if as a result of the
acquisition the purchaser would become a 45% shareholder of the company. There
is an exception to this provision, if someone else is already a majority
shareholder of the company. Regulations under the Companies Law provide that the
Companies Law's tender offer rules do not apply to a company whose shares are
publicly traded outside of Israel, if pursuant to the applicable foreign
securities laws and stock exchange rules there is a restriction on the
acquisition of any level of control of the company, or if the acquisition of any
level of control of the company requires the purchaser to make a tender offer to
the public shareholders.

Finally, Israeli tax law treats certain acquisitions, particularly
stock-for-stock swaps between an Israeli company and a foreign company, less
favorably than United States tax law. Israeli tax law may, for instance, subject
a shareholder who exchanges his company shares for shares in a foreign
corporation to immediate taxation.

Item 2. Properties

Our headquarters and principal administrative, finance, sales and
marketing and promotion operations are located in approximately 60,079 square
feet of leased office space in Tel Aviv, Israel at an approximate rental cost of
$1,164,000 in 2003. The lease for our principal offices expires in June 2005. In
the United States, we lease approximately 10,380 square feet of office space in
Glen Rock, New Jersey expiring in July 2004 and approximately 3,156 square feet
in Sunnyvale, California expiring in April 2004. We are in the final process of
signing a lease expiring in September 2007 for a 11,605 square foot building in
Fairlawn, New Jersey at a total annual rental of $191,499. We also lease
approximately 2,651 square feet in Hong Kong expiring in May 2004 and
approximately 800 square feet in the United Kingdom expiring in October 2005.
The aggregate annual rent for our sales and service offices in the United
States, Hong Kong, China and the United Kingdom was approximately $450,000 in
2003.

Item 3. Legal Proceedings

In January 2001, we entered into an agreement with Zohar Zisapel
Properties Inc. and Yehuda Zisapel Properties Inc. (entities that are wholly
owned by Zohar Zisapel, our Chairman of the Board and a principal shareholder,
and Yehuda Zisapel, a principal shareholder and our former Chairman,
respectively) to lease approximately 24,000 feet square of office space in

Paramus, New Jersey for a period of 5 years, which space we subsequently
surrendered. The parties disagreed as to the extent of damages caused by this
action, if any. In December 2003, the parties proceeded to binding arbitration
before Judge Robert E. Tarleton (retired) in Hackensack, New Jersey. The claim
filed against us was in the range of $1,500,000 and appropriate provision was
taken for such amount. Judge Tarleton issued his final ruling on February 12,
2004 stating the amount owed to Zisapel Properties is $400,000. This ruling will
not have a negative impact on our financial condition or results of operations.

Other than the above, we are not involved in any legal proceedings that
are material to our business or financial condition. From time to time we
receive requests from third parties to determine if we need to take out a
license to certain technology for which such third party may hold a patent or
other intellectual property right. We check such requests in the ordinary course
of business.

In 1998, Lucent sent correspondence to our affiliate, RAD Data
Communication Ltd., alleging that some products manufactured by RAD and some of
its affiliates, including us, infringe upon specified Lucent patents and
offering to license these patents to RAD and its affiliates. In subsequent
correspondence, RAD requested that Lucent specifically substantiate each
allegation of infringement before RAD or any of its affiliates considers
entering into any licensing arrangements. RAD has recently received further
correspondence from Lucent in which Lucent has reiterated its claims. RAD does
not believe Lucent has substantiated its claims and has communicated this belief
to Lucent. RAD advises us that the alleged infringement claims are unresolved.

The elements of our products that Lucent has alleged infringe upon its
patents are contained within components which we obtain from a third party
manufacturer. We believe that the third party manufacturer has a license to use
these patents and that we may be entitled to the benefits of this license.

In addition, based on Lucent's fee and royalty schedule for licensing
the relevant patents, we believe that any licensing fee and royalty payments
that we may be required to pay for the right to use Lucent's patents would not
have a material impact on our earnings. As a result, we do not believe that
Lucent's allegations will have a material adverse effect upon us, our business,
financial condition or liquidity.

Item 4. Submission of Matters to a Vote of Security Holders

No matters were submitted to a vote of securities holders during the
fourth quarter of the fiscal year ended December 31, 2003.

PART II

Item 5. Market for Registrant's Common Equity and Related Stockholder Matters

Our ordinary shares have traded on the Nasdaq National Market under the
symbol RVSN since our initial public offering on March 14, 2000. Since October
20, 2002, our ordinary shares have also traded on the Tel Aviv Stock Exchange.

The following table sets forth, for the periods indicated, the high and
low sale prices of our ordinary shares as reported by the Nasdaq National Market
and the Tel Aviv Stock Exchange:

Nasdaq National Market Tel Aviv Stock Exchange
---------------------- -----------------------
High Low High Low
---- --- ---- ---

----
First Quarter....... $7.90 $5.39 $ -- $ --
Second Quarter...... 6.80 4.40 -- --

Third Quarter....... 9.00 6.50 8.99 6.81
Fourth Quarter...... 13.26 7.81 12.97 7.99

As of March 8, 2004 we had approximately 2,523 beneficial shareholders
including 50 holders of record.

We have never paid dividends on our ordinary shares since our inception
and we do not anticipate paying any dividends in the foreseeable future. If we
were able to distribute cash dividends out of income that had been exempt from
tax because of our investment program's Approved Enterprise status (for
description of such status please refer to the section entitled "Effective
Corporate Tax Rate" in "Item 7. Management's Division and Analysis of Financial
Conditions and Results of Operations") such income would become subject to
Israeli corporate tax.

If we were to declare dividends in the future, we would declare those
dividends in NIS but pay those dividends to our non-Israeli shareholders in U.S.
dollars. Because exchange rates between NIS and the dollar fluctuate
continuously, a U.S. shareholder would be subject to currency fluctuation
between the date when the dividends were declared and the date the dividends
were paid.

Exchange Controls

Israeli law and regulations do not impose any material foreign exchange
restrictions on non-Israeli holders of our ordinary shares. In May 1998, a new
"general permit" was issued under the Israeli Currency Control Law, 1978, which
removed most of the restrictions that previously existed under such law, and
enabled Israeli citizens to freely invest outside of Israel and freely convert
Israeli currency into non-Israeli currencies.

Non-residents of Israel who purchase our ordinary shares will be able to
convert dividends, if any, thereon, and any amounts payable upon our
dissolution, liquidation or winding up, as well as the proceeds of any sale in
Israel of our ordinary shares to an Israeli resident, into freely repatriable
dollars, at the exchange rate prevailing at the time of conversion, provided
that the Israeli income tax has been withheld (or paid) with respect to such
amounts or an exemption has been obtained.

Dual Listing

In addition to trading on Nasdaq, on October 20, 2002, our ordinary
shares began trading on the Tel Aviv Stock Exchange. According to a publication
of the Israeli Tax Authorities, sales of securities of an industrial company,
such as us, by individuals and companies to whom Chapter B of the Inflationary
Law does not apply will continue to enjoy benefits of a lower Israeli capital
gains tax after a dual listing.

Taxation of Non-Resident Holders of Shares

Non-residents of Israel are subject to income tax on income accrued or
derived from sources in Israel. These sources of income include passive income,
such as dividends, royalties and interest, as well as non-passive income from
services provided in Israel. On distributions of dividends other than bonus
shares or stock dividends, income tax is withheld at the source. Unless a
different rate is provided in a treaty between Israel and the shareholder's
country of residence, the withholding rate is as follows:

Dividends not generated by an
approved enterprise
---------------------------------------------
U.S. company
Dividends generated by holding 10% or Other
an approved enterprise more of our shares non-resident
------------------------ ------------------------ ------------------
15% 12.5% 25%

Under an amendment to the Inflationary Adjustments Law, non-Israeli
corporations may be subject to Israeli taxes on the sale of publicly traded
securities of an Israeli company, subject to the provisions of any applicable
double taxation treaty.

Item 7. Management's Discussion and Analysis of Financial Condition and Results
of Operations

Operating Results

The following discussion of our results of operations should be read
together with our consolidated financial statements and the related notes, which
appear elsewhere in this annual report. The following discussion contains
forward-looking statements that reflect our current plans, estimates and beliefs
and involve risks and uncertainties. Our actual results may differ materially
from those discussed in the forward-looking statements. Factors that could cause
or contribute to such differences include those discussed below and elsewhere in
this annual report.

All of our revenues are generated in U.S. dollars or are linked to the
dollar and a majority of our expenses are incurred in U.S. dollars.
Consequently, we use the dollar as our functional currency. Transactions and
balances in other currencies are re-measured into dollars according to the
principles in Financial Accounting Standards Board Statement No. 52. Gains and
losses arising from re-measurement are reflected in the statements of operations
as financial income or expenses as appropriate.

Overview

We are a leading designer, developer and supplier of products and
technology that enable real-time voice, video and data communication over packet
networks, including the Internet and other IP networks. We were incorporated in
January 1992, commenced operations in October 1992 and commenced sales of
our products in the fourth quarter of 1994. Before that time, our operations
consisted primarily of research and development and recruiting personnel. In
1995, we established a wholly owned subsidiary in the United States, RADVISION
Inc., which conducts our sales and marketing activities in North America.
We currently have sales offices in the United States and Israel and marketing,
representative and liaison offices in Brazil, China, Hong Kong, India, Japan and
the United Kingdom.

Critical Accounting Estimates

We have identified the following policies as critical to the
understanding of our financial statements. The preparation of our financial
statements requires management to make estimates and assumptions that affect the
reported amounts of assets and liabilities and disclosure of contingent assets
and liabilities at the date of the financial statements and the reported amounts
of sales and expenses during the reporting periods. Areas where significant
judgments are made include, but are not limited to, inventory valuation,
warranty and revenue recognition. Actual results could differ materially from
these estimates. Our consolidated financial statements have been prepared in
accordance with accounting principles generally accepted in the United States.

Inventories. Inventories are stated at the lower of cost or market. Cost
is determined by the moving average method, inventory write-offs and write-down
provisions are provided to cover risks arising from slow-moving items or
technological obsolescence.

Revenue Recognition. We recognize revenues in respect of products when,
among other things, we have delivered the goods being purchased and we believe
collectibility to be reasonably assured. We do not grant a right of return to
our customers. We perform ongoing credit evaluations of our customers' financial
condition and we require collateral as deemed necessary. We maintain allowances
for doubtful accounts for estimated losses resulting from the inability of our
customers to make payments. In judging the adequacy of the allowance for
doubtful accounts, we consider multiple factors including the aging of our
receivables, historical bad debt experience and the general economic
environment. Management applies considerable judgment in assessing the
realization of receivables, including assessing the probability of collection
and the current creditworthiness of each customer. If the financial condition of
our customers were to deteriorate, resulting in an impairment of their ability
to make payments, additional allowances may be required.

Warranty Reserves. Upon shipment of products to our customers, we
provide for the estimated cost to repair or replace products that may be
returned under warranty. Our warranty period is typically 12 months from the
date of shipment to the end user customer. For existing products, the reserve is
estimated based on actual historical experience. For new products, the
warranty reserve is based on historical experience of similar products until
such time as sufficient historical data has been collected on the new product.
Factors that may impact our warranty costs in the future include our reliance on
our contract manufacturer to provide quality

products and the fact that our products are complex and may contain undetected
defects, errors or failures in either the hardware or the software. Warranty
reserves amounted to $550,000 and $350,000 at December 31, 2003 and 2002,
respectively.

Revenues

We generate revenues from sales of our networking products that are
primarily sold in the form of stand-alone products, and our technology products
that are primarily sold in the form of software development kits, as well as
related maintenance and support services. We generally recognize revenues from
the sale of our products upon shipment and when collection is probable. Revenues
generated from maintenance and support services are deferred and recognized
ratably over the period of the term of service. We price our networking products
on a per unit basis, and grant discounts based upon unit volumes. We price our
software development kits on the basis of a fixed-fee plus royalties from
products developed using the software development kits. We sell our products and
technology through direct sales and various indirect distribution channels in
North America, Europe, the Middle East and Far East. For the year ended December
31, 2003, approximately 46.2% of our revenues were generated in the United
States.

Significant Costs and Expenses

Cost of Revenues Our cost of revenues consists of component and material
costs, direct labor costs, subcontractor fees, overhead related to manufacturing
and depreciation of manufacturing equipment. Our gross margin is affected by the
selling prices for our products as well as the proportion of our revenues
generated from the sale of our technology products as compared to our networking
products. Our revenues from the sale of our technology products have higher
gross margins than our revenues from the sale of our networking products and we
offer greater discounts to our high volume OEM customers. As the relative
proportion of our revenues from our networking products increases as a
percentage of our total revenues and we generate a higher percentage of our
revenues from sales to our high volume OEM customers, our gross margins will
decline.

Research and development expenses, net. Our research and development
expenses consist primarily of compensation and related costs for research and
development personnel, expenses for testing facilities and depreciation of
equipment.

Research and development costs, net are charged to operations as
incurred. Software development costs are considered for capitalization when
technological feasibility is established according to SFAS No. 86, "Accounting
for the Costs of Computer Software to be Sold, Leased or Otherwise Marketed."
Costs incurred after achievement of technological feasibility in the process of
software production have not been material. Therefore, we have not capitalized
any of our research and development expenses and do not anticipate that our
development process will differ materially in the future.

Historically our research and development expenses were presented net of
payments received from the Office of the Chief Scientist of Israeli Ministry of
Industry and Trade, or the Chief Scientist. In 2000 we voluntarily repaid
$3,666,000 in future royalty payments to the Chief Scientist and discontinued
our relationship with the Chief Scientist in order to reduce certain
restrictions on our business and to avoid paying increased interest rates in the
future on royalty payments. We do not currently intend to apply for grants from
the Chief Scientist in the future. However, we expect to continue to make
substantial investments in research and development.

Marketing and selling expenses, net. Our marketing and selling expenses
consist primarily of compensation and related costs for sales personnel,
marketing personnel, sales commissions, marketing programs, public relations,
promotional materials, travel expenses, trade show exhibit expenses and
royalties paid to the Government of Israel. Marketing and selling expenses until
December 31, 1999 are presented net of marketing grants received from the
Government of Israel. We do not intend to apply for any grants from the
Government of Israel in the future.

General and administrative expenses. Our general and administrative
expenses consist primarily of salaries and related expenses for executive,
accounting and human resources personnel, professional fees, provisions for
doubtful accounts and other general corporate expenses.

Operating expenses also include amortization of stock-based
compensation, which is allocated among research and development expenses,
marketing and selling expenses and general and administrative expenses based on
the division in which the recipient of the option grant is employed.
Amortization of stock-based compensation results from the granting of options to
employees with exercise prices per share determined to be below the fair market
value per share of our ordinary shares on the dates of grant. The stock-based
compensation is being amortized to operating expenses over the vesting period of
the individual options.

Financial income, net. Our financial income consists primarily of
interest earned on bank deposits and other liquid investments, gains and losses
from the re-measurement of monetary balance sheet items denominated in
non-dollar currencies into dollars and interest expense incurred on outstanding
debt.

Taxes. Israeli companies are generally subject to income tax at the
corporate tax rate of 36%. However, several of our investment programs at our
manufacturing facility in Tel Aviv have been granted approved enterprise status
and, therefore, we are eligible for tax benefits. These benefits should result
in income recognized by us being tax exempt or taxed at a lower rate for a
specified period after we begin to report taxable income and exhaust any net
operating loss carry-forwards. However, these benefits may not be applied to
reduce the tax rate for any income derived by our U.S. subsidiary.

Results of Operations

The following discussion of our results of operations for the years
ended December 31, 2001, 2002 and 2003, including the percentage data in the
following table, is based upon our statements of operations contained in our
financial statements for those periods, and the related notes, included in this

Year Ended December 31, 2003 as Compared with Year Ended December 31, 2002

Revenues. Revenues increased 4.5% from $49.1 million for the year ended
December 31, 2002 to $51.3 million for the year ended December 31, 2003. This
increase was due to increased sales of networking products. Revenues from
networking products increased 4.7% from $36.3 million for the year ended
December 31, 2002 to $38.1 million for the year ended December 31, 2003. The
increase in revenue from networking products is attributable to an increase in
demand for these units as customers moved from integrated services digital
networks, or ISDN, to IP-based networks. Revenues from technology products
increased 3.8% from $12.8 million for the year ended December 31, 2002 to $13.2
million for the year ended December 31, 2003. This slight increase in revenues
from technology products was primarily attributable to approximately $900,000 in
research and development services by our Professional Services Division, which
we began to offer in the first quarter of 2003.

Revenue from sales to customers in the United States decreased from
$24.1 million, or 49.0% of revenue, for the year ended December 31, 2002, to
$23.7 million, or 46.2% of revenue, for the year ended December 31, 2003, a
decrease of $400,000, or 1.7%. Revenue from sales to customers in Europe
decreased from $12.0 million, or 24.5% of revenue, for the year ended December
31, 2002, to $11.2 million, or 21.8% of revenue, for the year ended December 31,
2003, a decrease of $800,000, or 6.7%. This decrease in sales to customers in
Europe was primarily attributable to the ongoing softness in enterprise spending
in Europe. Revenue from sales to customers in the Far East increased from $10.2
million, or 20.8% of revenue, for the year ended December 31, 2002, to $12.7
million, or 24.8% of revenue, for the year ended December 31, 2003, an increase
of $2.5 million, or 24.5%. This increase in sales to customers in this region

was primarily attributable to increased sales efforts for our networking
products. Revenue from sales to customers in Israel increased from $2.3 million,
or 4.6% of revenue, for the year ended December 31, 2002, to $3.0 million, or
5.8% of revenue, for the year ended December 31, 2003, an increase of $700,000,
or 30.4%. This increase in sales to customers in Israel was primarily
attributable to increased sales efforts for our networking products.

Cost of Revenues. Cost of revenues increased from $10.9 million for the
year ended December 31, 2002 to $11.4 million for the year ended December 31,
2003, an increase of $500,000, or 4.6%. Gross profit as a percentage of revenues
increased from 77.7% for the year ended December 31, 2002 to 77.9% for the year
ended December 31, 2003.

Research and Development. Research and development expenses decreased
from $15.3 million for the year ended December 31, 2002 to $14.6 million for the
year ended December 31, 2003, a decrease of $700,000, or 4.6%. We have decreased
our research and development personnel consistent with the scope of our research
and development programs. Research and development expenses as a percentage of
revenues decreased from 31.2% for the year ended December 31, 2002 to 28.4% for
the year ended December 31, 2003.

Marketing and Selling. Marketing and selling expenses increased from
$18.6 million for the year ended December 31, 2002 to $20.0 million for the year
ended December 31, 2003, an increase of $1.4 million, or 7.5%. We increased our
marketing and selling expenses in response to current and expected continued
improvement in the market for our networking products. Marketing and selling
expenses as a percentage of revenues increased from 37.9% for the year ended
December 31, 2002 to 38.9% for the year ended December 31, 2003.

General and Administrative. General and administrative expenses
decreased from $4.1 million for the year ended December 31, 2002 to $4.0 million
for the year ended December 31, 2003, a decrease of $100,000, or 2.4%. This
decrease was primarily attributable to a decrease in personnel expenses. General
and administrative expenses as a percentage of revenues decreased from 8.4% for
the year ended December 31, 2002 to 7.9% for the year ended December 31, 2003.

Financial Income, Net. Financial income decreased from $2.7 million for
the year ended December 31, 2002 to $2.1 million for the year ended December 31,
2003 principally as a result of lower interest rates.

Year Ended December 31, 2002 as Compared with Year Ended December 31, 2001

Revenues. Revenues increased from $46.2 million for the year ended
December 31, 2001 to $49.1 million for the year ended December 31, 2002. This
increase was due to increased sales of networking products. Revenues from
networking products increased from $29.7 million for the year ended December 31,
2001 to $36.3 million for the year ended December 31, 2002. The increase in
revenue from networking products is attributable to an increase in demand for
these units as customers moved from integrated services digital networks, or
ISDN, to IP-based networks, as well as from the sale of an integrated
videoconferencing solution to FastWeb, a Milan-based service provider that
provides bundled broadband voice, video and data services to consumers and
businesses throughout Italy. Revenues from technology products decreased from

$16.5 million for the year ended December 31, 2001 to $12.8 million for the year
ended December 31, 2002. This decrease in revenues from technology products was
primarily attributable to decreased market demand as budgets for these products
declined due to the worldwide economic downturn.

Revenue from sales to customers in the United States decreased from
$28.3 million, or 61.3% of revenue, for the year ended December 31, 2001, to
$24.1million, or 49.0% of revenue, for the year ended December 31, 2002, a
decrease of $4.2 million, or 14.8%. Revenue from sales to customers in Europe
increased from $8.1 million, or 17.5% of revenue, for the year ended December
31, 2001, to $12.1 million, or 24.5% of revenue, for the year ended December 31,
2002, an increase of $4.0 million, or 49.4%. This increase in sales to customers
in Europe was primarily attributable to increased market demand for our products
in this region and due to the FastWeb sale. Revenue from sales to customers in
the Far East increased from $6.9 million, or 15.0% of revenue, for the year
ended December 31, 2001, to $10.2 million, or 20.8% of revenue, for the year
ended December 31, 2002, an increase of $3.3 million, or 47.8%. This increase in
sales to customers in this region was primarily attributable to increased sales
efforts for our networking products. Revenue from sales to customers in Israel
increased from $1.9 million, or 4.2% of revenue, for the year ended December 31,
2001, to $2.3 million, or 4.6% of revenue, for the year ended December 31, 2002,
an increase of $400,000, or 21.1%. This increase in sales to customers in Israel
was primarily attributable to increased sales efforts for our networking
products.

Cost of Revenues. Cost of revenues increased from $10.4 million for the
year ended December 31, 2001 to $10.9 million for the year ended December 31,
2002, an increase of $500,000, or 4.8%. Gross profit as a percentage of revenues
increased from 77.6% for the year ended December 31, 2001 to 77.7% for the year
ended December 31, 2002.

Research and Development. Research and development expenses decreased
from $17.9 million for the year ended December 31, 2001 to $15.3 million for the
year ended December 31, 2002, a decrease of $2.6 million, or 14.5%. We have
decreased our research and development personnel consistent with the scope of
our research and development programs. Research and development expenses as a
percentage of revenues decreased from 38.8% for the year ended December 31, 2001
to 31.2% for the year ended December 31, 2002.

Marketing and Selling. Marketing and selling expenses increased from
$16.7 million for the year ended December 31, 2001 to $18.6 million for the year
ended December 31, 2002, an increase of $1.9 million, or 11.4%. We increased our
sales and marketing expenses in response to current and expected continued
improvement in the market for our networking products. Marketing and selling
expenses as a percentage of revenues increased from 36.2% for the year ended
December 31, 2001 to 37.9% for the year ended December 31, 2002.

General and Administrative. General and administrative expenses
decreased from $4.4 million for the year ended December 31, 2001 to $4.1 million
for the year ended December 31, 2002, a decrease of $300,000, or 6.8%. This
decrease was primarily attributable to a decrease in personnel expenses. General
and administrative expenses as a percentage of revenues decreased from 9.6% for
the year ended December 31, 2001 to 8.4% for the year ended December 31, 2002.

Financial Income, Net. Financial income decreased from $4.7 million for
the year ended December 31, 2001 to $2.7 million for the year ended December 31,
2002 principally as a result of lower interest rates.

Consolidated Balance Sheet Data

Trade Receivables. Trade receivables decreased from $9.5 million at
December 31, 2002 to $8.7 million at December 31, 2003, a decrease of $800,000,
or $8.4%. This decrease was primarily attributable to one-time event associated
with the FastWeb deal in the fourth quarter of 2002 that was paid in the first
quarter of 2003.

Allowance for Doubtful Accounts. Allowance for doubtful accounts
increased from $1,593,000 at December 31, 2002 to $1,704,000 at December 31,
2003, an increase of $111,000, or 7.0% due to increased sales in the last two
quarters of 2003 compared to revenues for the last two quarters of 2002.
Allowance for doubtful accounts as a portion of trade receivables decreased from
14.4% as of December 31, 2002 to 16.4% as of December 31, 2003.

Other Receivables and Prepaid Expenses. Other receivables and prepaid
expenses decreased from $2.8 million at December 31, 2002 to $2.7 million at
December 31, 2003, a decrease of $100,000, or 3.6%.

Inventories. Inventories remained relatively constant at approximately
$1.0 million at December 31, 2002 and December 31, 2003. Our management of
inventory levels improved in 2003 as measured by our increased level of sales
and the number of inventory days outstanding, which decreased from 29 days at
December 31, 2002 to 26 days at December 31, 2003.

Trade Payables. Trade payables decreased from $ 3.3 million at December
31, 2002 to $1.3 million at December 31, 2003, a decrease of $2.0 million, or
60.6%, primarily due to the one time FastWeb deal that increased our trade
payables and trade receivables balances at December 31, 2002 and were paid in
2003.

Other Payables, Accrued Expenses and Deferred Revenues. Other payables
and accrued expenses increased from $15.2 million at December 31, 2002 to $19.1
million at December 31, 2003, an increase of $3.9 million, or 25.7%. This
increase was primarily attributable to an increase of accruals relating to the
purchase of material and an increase in deferred income related to technology
sales that will be recognized in the future upon providing maintenance service.

Quarterly Results of Operations

The following tables present consolidated statements of operations data
for each of the eight fiscal quarters ended December 31, 2003, in dollars and as
a percentage of revenues. In management's opinion, this unaudited information
has been prepared on the same basis as our audited consolidated financial
statements and includes all adjustments, consisting only of normal recurring
adjustments, necessary for fair presentation of the unaudited information for
the quarters presented. The results of operations for any quarter are not

We expect our operating results to fluctuate significantly in the future
as a result of various factors, many of which are outside our control.
Consequently, we believe that period-to-period comparisons of our operating
results may not necessarily be meaningful and, as a result, you should not rely
on them as an indication of future performance.

Liquidity and Capital Resources

From our inception until our initial public offering in March 2000, we
financed our operations through cash generated by operations and a combination
of private placements of our share capital and borrowings under lines of credit.
Through December 31, 1999, we raised a total of approximately $12.2 million in
aggregate net proceeds in four private placements. In March 2000, we sold
4,370,000 of our ordinary shares in an initial public offering and 590,822
ordinary shares in a private placement to Samsung Venture Investment
Corporation, a member of the Samsung group, and Siemens Aktiengesellschraft. We
received net proceeds of $89.2 million from the public offering and private
placement.

As of December 31, 2003, we had approximately $16.4 million in cash and
cash equivalents, $35.0 million in short term investments and our working
capital was approximately $43.4 million. Taking into account long-term liquid
investments, we had $99.9 million in cash and liquid investments as of December
31, 2003.

Another financial measure that our management believes is important in
assessing our company's financial condition is days sales outstanding, or DSOs.
In 2003, we achieved

significant success in reducing the number of DSOs from 64 days at December 31,
2002 to 43 days (well below our target of 55 days) at December 31, 2003.

Capital expenditures for the years ended December 31, 2001, 2002 and
2003 were approximately $2.0 million, $1.7 million and $1.3 million,
respectively. These expenditures were principally for research and development
equipment, motor vehicles, office furniture and equipment and leasehold
improvements. We currently do not have significant capital spending or purchase
commitments, but we expect to continue to engage in capital spending consistent
with anticipated growth in our operations, infrastructure and personnel. Net
cash provided by operating activities was approximately $7.5 million for the
year ended December 31, 2003. This amount was primarily attributable to a net
profit of $3.5 million, an increase of $3.2 million in deferred revenues, a
decrease of $820,000 in trade receivables and an increase in depreciation of
$1.9 million. These increases in cash provided by operating activities were
offset in part by a decrease in trade payables of $2.1 million.

Net cash used in investing activities was approximately $9.6 million for
the year ended December 31, 2003. For the year ended December 31, 2003, $75.3
million of cash provided by investing activities were from sales of bank
deposits and marketable securities and $83.7 million were invested in long term
investments. During the year ended December 31, 2003, $1.3 million of cash used
in investing activities was for purchases of property and equipment.

On February 28, 2001, we announced that our board of directors
authorized the repurchase of up to 10% of our outstanding shares in open market
transactions at prevailing market prices. We completed the share repurchase
program in the first fiscal quarter of 2002, having purchased 1,866,117 ordinary
shares at a total cost of $11.8 million, or an average price of $6.30 per share.

On August 28, 2002, we announced that our board of directors authorized
the repurchase of up to $10 million or 2 million of our ordinary shares in the
open market from time to time at prevailing market prices. During April 2003, we
started to repurchase our ordinary shares based on the instruction of our board
of directors. As of December 31, 2003, we had purchased 14,000 ordinary shares
at a total cost of $78,000, or an average price of $5.55 per share.

Net cash provided by financing activities was $4.6 million for the year
ended December 31, 2003, as compared to $4.1 million in the year ended December
31, 2002. For both years, cash provided by financing activities was principally
attributable to the issuance of ordinary shares and treasury stock for cash upon
exercise of options.

As of December 31, 2003, our principal commitments consisted of
obligations outstanding under operating leases. Our capital requirements are
dependent on many factors, including market acceptance of our products and the
allocation of resources to our research and development efforts, as well as our
marketing and sales activities. In the last three years, we have experienced
substantial increases in our expenditures as a result of the growth in our
operations and personnel. We intend to increase our expenditures in the future
consistent with our anticipated growth. We anticipate that our cash resources
will be used primarily to fund our operating activities, as well as for capital
expenditures.

As of December 31, 2003, we had an unused $2.5 million line of credit.

Effective Corporate Tax Rate

Israeli companies are generally subject to income tax at the corporate
tax rate of 36%. However, several investment programs at our manufacturing
facility in Tel Aviv have been granted approved enterprise status and we are,
therefore, eligible for tax benefits under the Law for the Encouragement of
Capital Investments, 1959. We have derived, and expect to continue to derive, a
substantial portion of our income from the approved enterprise programs at our
manufacturing facility.

Subject to compliance with applicable requirements, the portion of our
income derived from the approved enterprise programs will be eligible for the
following tax benefits commencing in the first year in which it generates
taxable income:

Year after we
begin generating
taxable income Tax benefit
------------------- ------------------------------------------------
1-2............... Tax-exempt
3-7............... Corporate tax of up to 25%
8-10.............. Corporate tax of up to 25% if more than 25% of
our shares are held by (per Israeli Tax
Authorities' position - invested by) non-Israeli
investors

The period of tax benefits for our approved enterprise programs has not
yet commenced, because we have yet to realize taxable income. These benefits
should result in income recognized by us being tax exempt or taxed at a lower
rate for a specified period after we begin to report taxable income and exhaust
any net operating loss carry-forwards. However, these benefits may not be
applied to reduce the tax rate for any income derived by our U.S. subsidiary.

As of December 31, 2003, our net operating loss carry-forwards for
Israeli tax purposes amounted to approximately $16.5 million. Under Israeli law,
these net-operating losses may be carried forward indefinitely and offset
against future taxable income. We expect that, during the period in which these
tax losses are utilized, our income will be substantially tax-exempt. Therefore,
there will be no tax benefit available from these losses and no deferred income
taxes have been included in our financial statements. Deferred taxes for other
temporary differences are immaterial.

As of December 31, 2003, the net operating loss carry-forwards of our
U.S. subsidiary for U.S. tax purposes amounted to approximately $14.0 million.
These losses are available to offset any future U.S. taxable income of our U.S.
subsidiary and will expire in the years 2010 through 2022.

Impact of Inflation and Currency Fluctuations

The dollar cost of our operations is influenced by the extent to which
any inflation in Israel is offset on a lagging basis, or is not offset by the
devaluation of the NIS in relation to the dollar. When the rate of inflation in
Israel exceeds the rate of devaluation of the NIS against the

dollar, companies experience increases in the dollar cost of their operations in
Israel. Unless offset by a devaluation of the NIS, inflation in Israel will have
a negative effect on our profitability as we receive payment in dollars or
dollar-linked NIS for all of our sales while we incur a portion of our expenses,
principally salaries and related personnel expenses, in NIS.

The following table presents information about the rate of inflation in
Israel, the rate of devaluation of the NIS against the U.S. dollar, and the rate
of inflation of Israel adjusted for the devaluation:

Israeli
Israeli Israeli inflation
Year ended inflation devaluation rate adjusted for
December 31, rate % % devaluation %
------------ --------- ---------------- -------------
1996 10.6 3.7 6.6
1997 7.0 8.8 (1.7)
1998 8.6 17.6 (7.7)
1999 1.3 (0.1) 1.3
2000 0.0 (2.7) 2.8
2001 1.4 9.3 (7.8)
2002 6.5 7.3 (0.7)
2003 (1.9) (7.6) 6.1

We cannot assure you that we will not be materially and adversely
affected in the future if inflation in Israel exceeds the devaluation of the NIS
against the dollar or if the timing of the devaluation lags behind inflation in
Israel.

A devaluation of the NIS in relation to the dollar has the effect of
reducing the dollar amount of any of our expenses or liabilities which are
payable in NIS, unless these expenses or payables are linked to the dollar. This
devaluation also has the effect of decreasing the dollar value of any asset
which consists of NIS or receivables payable in NIS, unless the receivables are
linked to the dollar. Conversely, any increase in the value of the NIS in
relation to the dollar has the effect of increasing the dollar value of any
unlinked NIS assets and the dollar amounts of any unlinked NIS liabilities and
expenses.

Because exchange rates between the NIS and the dollar fluctuate
continuously, with a historically declining trend in the value of the NIS,
exchange rate fluctuations and especially larger periodic devaluations will have
an impact on our profitability and period-to-period comparisons of our results.
The effects of foreign currency re-measurements are reported in our consolidated
financial statements in current operations.

Off-Balance Sheet Arrangements

We are not a party to any material off-balance sheet arrangements. In
addition, we have no unconsolidated special purpose financing or partnership
entities that are likely to create material contingent obligations.

Tabular Disclosure of Contractual Obligations

The following table summarizes our minimum contractual obligations and
commercial commitments, including obligations of discontinued operations, as of
December 31, 2003 and the

effect we expect them to have on our liquidity and cash flow in future periods.

Contractual Obligations Payments due by Period

Research and development activities are vital for our continued success.
In 2003, we expended $14.6 million for research and development and believe that
our expenditures in 2004 will not change materially.

Item 7A. Qualitative and Qualitative Disclosures About Market Risk

We are exposed to a variety of risks, including changes in interest
rates and foreign currency fluctuations.

Interest Rate Risk

As of December 31, 2003, we had cash and cash equivalents and short-term
investments of $51.4 million. We invest our cash surplus in time deposits, cash
deposits, U.S. federal agency securities and corporate bonds with an average
credit rating of A2. These investments are not purchased for trading or other
speculative purposes. Due to the nature of these investments, we believe that we
do not have a material exposure to market risk.

Our exposure to market risks for changes in interest rates is limited
since we do not have any material indebtedness.

Foreign Currency Exchange Risk

We develop products in Israel and sell them in North America, Asia and
several European countries. As a result our financial results could be affected
by factors such as changes in foreign currency exchange rates or weak economic
conditions in foreign markets.

Our foreign currency exposure with respect to our sales is mitigated,
and we expect it will continue to be mitigated, through salaries, materials and
support operations, in which part of these costs are denominated in NIS.

Since the beginning of 2003, the NIS has revalued approximately 7.6%
against the dollar. Among the factors contributing to the revaluation are the
low interest rate for US$ investments compared to the higher interest rate for
NIS investments. The revaluation has resulted in a

deflation in Israel, which was approximately 1.9% for the year 2003 compared to
an annual inflation rate of 6.5% for 2002.

Since most of our sales are quoted in $, and a portion of our expenses
are incurred in NIS, our results may be adversely affected by a change in the
rate of inflation in Israel or if such change in the rate of inflation is not
offset, or is offset on a lagging basis, by a corresponding devaluation of the
NIS against the dollar and other foreign currencies.

During 2002 we entered into one foreign exchange contract. The foreign
exchange contract was for 400,000 Euros and was closed in early 2003 at a slight
loss.

Item 8. Financial Statement and Supplementary Data

See Index to Financial Statements on page F-1 for a list of the
financial statements being filed therein.

Item 9. Changes in and Disagreements with Accountants on Accounting and
Financial Disclosure

Not applicable.

Item 9A. Controls and Procedures

During the year 2003, we carried out an evaluation, under the
supervision and with the participation of our management, including our chief
executive officer and chief financial officer, of the effectiveness of the
design and operation of our company's disclosure controls and procedures
pursuant to Rule 13a-14 of the Securities Exchange Act of 1934. Based upon that
evaluation, our chief executive officer and chief financial officer concluded
that our company's disclosure controls and procedures are effective in timely
alerting them to material information relating to our company required to be
included in our company's periodic SEC filings.

There have been no significant changes in our internal controls or other
factors which could significantly affect internal controls subsequent to the
date we carried out the evaluation.

It should be noted that any system of controls, however well designed
and operated, can provide only reasonable, and not absolute, assurance that the
objectives of the system are met. In addition, the design of any control system
is based in part upon certain assumptions about the likelihood of future events.
Because of these and other inherent limitations of control systems, there can be
no assurance that any design will succeed in achieving its stated goals under
all potential future conditions.

Election of Directors

Pursuant to our articles of association, all of our directors, other
than our outside directors, are elected at our annual general meeting of
shareholders by a vote of the holders of a majority of the voting power
represented and voting at such meeting. Outside directors are elected for a
three-year term. All the members of our Board of Directors, except the outside
directors, may be reelected upon completion of their term of office. In the
intervals between annual general meetings of the company, our Board of Directors
may elect new directors, whether to fill vacancies or in addition to those of
their body, but only if the total numbers of directors shall not at any time
exceed any maximum number, if any, fixed by or in accordance with our articles
of association. Five of our directors currently in office were elected by our
shareholders at our 2002 annual general meeting of shareholders.

Independent and Outside Directors

The Israeli Companies Law requires Israeli companies with shares that
have been offered to the public in or outside of Israel to appoint at least two
outside directors. No person may be appointed as an outside director if the
person or the person's relative, partner, employer or any entity under the
person's control has or had, on or within the two years preceding the date of
the person's appointment to serve as outside director, any affiliation with the
company or any entity controlling, controlled by or under common control with
the company. The term affiliation includes:

o an employment relationship;

o a business or professional relationship maintained on a regular basis;

o control; and

o service as an officer holder.

No person may serve as an outside director if the person's position or
other activities create, or may create, a conflict of interest with the person's
responsibilities as an outside director or may otherwise interfere with the
person's ability to serve as an outside director. If, at the time outside
directors are to be appointed, all current members of the Board of Directors are
of the same gender, then at least one outside director must be of the other
gender.

Outside directors are elected by shareholders. The shareholders voting
in favor of their election must include at least one-third of the shares of the
non-controlling shareholders of the company who are present at the meeting. This
minority approval requirement need not be met if the total shareholdings of
those non-controlling shareholders who vote against their election represent 1%
or less of all of the voting rights in the company. Outside directors serve for
a three-year term, which may be renewed for only one additional three-year term.
Outside directors can be removed from office only by the same special percentage
of shareholders as can elect them, or by a court, and then only if the outside
directors cease to meet the statutory qualifications with respect to their
appointment or if they violate their duty of loyalty to the company.

Any committee of the board of directors must include at least one
outside director and the audit committee must include all of the outside
directors. An outside director is entitled to compensation as provided in
regulations adopted under the Companies Law and is otherwise prohibited from
receiving any other compensation, directly or indirectly, in connection with
such service.

In addition, the Nasdaq Stock Market requires us to have at least three
independent directors on our Board of Directors and to establish an audit
committee, at least a majority of whose members are independent of management.
Our current audit committee complies with the Nasdaq rules.

Audit Committee

Our audit committee, established in accordance with Section 114 of the
Israeli Companies Law and Section 3(a)(58)(A) of the Securities Exchange Act of
1934, assists our board of directors in overseeing the accounting and financial
reporting processes of our company and audits of our financial statements,
including the integrity of our financial statements, compliance with legal and
regulatory requirements, our independent public accountants' qualifications and
independence, the performance of our internal audit function and independent
public accountants, finding any defects in the business management of our
company for which purpose the audit committee may consult with our independent
auditors and internal auditor, proposing to the board of directors ways to
correct such defects, approving related-party transactions as required by
Israeli law, and such other duties as may be directed by our board of directors.

Our audit committee is currently composed of Joseph Atsmon, Liora
Katzenstein and Efraim Wachtel, each of whom satisfies the requirement
applicable to members of audit committees. Joseph Atsmon has been elected as the
Chairperson of the Audit Committee. The audit committee meets at least once each
quarter. Our Audit Committee charter is available on our website at
www.radvision.com.

Under Israeli law, an audit committee may not approve an action or a
transaction with a controlling shareholder, or with an office holder, unless at
the time of approval two outside directors are serving as members of the audit
committee and at least one of the outside directors was present at the meeting
in which an approval was granted.

Our Audit Committee is authorized generally to investigate any matter
within the scope of its responsibilities and has the power to obtain from the
internal auditing unit, our independent auditors or any other officer or
employee any information that is relevant to such investigations.

Our Audit Committee has adopted and our Board of Directors has approved
a company-wide Code of Business Ethics which appears on our company's website.

Audit Committee Financial Expert

Our board of directors has determined that Joseph Atsmon meets the
definition of an audit committee financial expert, as defined in Item 401 of
Regulation S-K.

Other Committees

In addition to our audit committee, our board of directors has
established an option committee and an executive committee.

Our option committee, whose members are Zohar Zisapel, Efraim Wachtel
and Gad Tamari, administers our consultants option plan. The Board of Directors
serves as the compensation committee of our board directors and sets the annual
compensation for Gad Tamari, our chief executive officer. Mr. Tamari does not
participate in any discussions or decisions that involve any aspect of his
compensation.

Internal Audit

The Israeli Companies Law also requires the board of directors of a
public company to appoint an internal auditor nominated by the audit committee.
A person who does not satisfy the Companies Law's independence requirements may
not be appointed as an internal auditor. The role of the internal auditor is to
examine, among other things, the compliance of the company's conduct with
applicable law and orderly business practice. Our internal auditor complies with
the requirements of the Companies Law. Our Internal Auditor is currently Mr.
Gideon Duvshani, C.P.A. of Schwartz, Lerner, Duvshani & Co.

Approval of Related Party Transactions Under Israeli Law

The Companies Law codifies the fiduciary duties that "office holders",
including directors and executive officers, owe to a company. An "office holder"
is defined in the Companies Law as a director, general manager, chief business
manager, deputy general manager, vice general manager, other manager directly
subordinate to the managing director or any other person assuming the
responsibilities of any of the foregoing positions without regard to such
person's title. An office holder's fiduciary duties consist of a duty of care
and a duty of loyalty. The duty of care requires an office holder to act at a
level of care that a reasonable office holder in the same position would employ
under the same circumstances. This includes the duty to utilize reasonable means
to obtain (i) information regarding the appropriateness of a given action
brought for his approval or performed by him by virtue of his position and (ii)
all other information of importance pertaining to the foregoing actions. The
duty of loyalty includes avoiding any conflict of interest between the office
holder's position in the company and his personal affairs, avoiding any
competition with the company, avoiding exploiting any business opportunity of
the company in order to receive personal gain for the office holder or others,
and disclosing to the company any information or documents relating to the
company's affairs which the office holder has received due to his position as an
office holder. Each person identified as a director or executive officer in the
first table in the section is an office holder. Under the Companies Law and our
Articles of Association, all arrangements as to compensation of office holders
who are not directors require approval of our Audit Committee and Board of
Directors if the transaction is an "extraordinary transaction", or if such
transaction is not an "extraordinary transaction," the approval of our General
Manager according to guidelines of the Board of Directors. The compensation of
office holders who are directors must be approved by our Audit Committee, Board
of Directors and shareholders.

The Companies Law requires that an office holder promptly disclose any
personal interest that he or she may have and all related material information
known to him or her, in connection with any existing or proposed transaction by
us. In addition, if the transaction is an extraordinary transaction, that is, a
transaction other than in the ordinary course of business, other than on market
terms, or likely to have a material impact on the company's profitability,
assets or liabilities, the office holder must also disclose any personal
interest held by the office holder's spouse, siblings, parents, grandparents,
descendants, spouse's descendants and the spouses of any of the foregoing, or by
any corporation in which the office holder or a relative is a 5% or greater
shareholder, director or general manager or in which he or she has the right to
appoint at least one director or the general manager. Some transactions, actions
and arrangements involving an office holder (or a third party in which an office
holder has an interest) must be approved by the board of directors or as
otherwise provided for in a company's articles of association, as not being
adverse to the company's interest. In some cases, such a transaction must be
approved by the audit committee and by the board of directors itself (with
further shareholder approval required in the case of extraordinary
transactions). An office holder who has a personal interest in a matter, which
is considered at a meeting of the board of directors or the audit committee, may
not be present during the board of directors or audit committee discussions and
may not vote on this matter, unless the majority of the members of the board or
the audit committee have a personal interest, as the case may be, in which case
such transaction will also require the approval of shareholders.

The Companies Law also provides that some transactions between a public
company and a controlling shareholder, or transactions in which a controlling
shareholder of the company has a personal interest but which are between a
public company and another entity, require the approval of the board of
directors and of the shareholders. The Companies Law defines a controlling
shareholder as a person who holds 25% or more of the voting rights at the
company's general meeting, provided there is no other person that holds more
than 50% of the voting rights in the company; for purposes of holding, two or
more persons who hold voting rights in the company and each of whom has a
personal interest in the approval of the same transaction up for approval by the
company shall be deemed one holder. Moreover, an extraordinary transaction with
a controlling shareholder or the terms of compensation of a controlling
shareholder, or an extraordinary transaction with another person in whom the
controlling shareholder has a personal interest must be approved by the audit
committee, the board of directors and shareholders. The shareholder approval for
an extraordinary transaction must include at least one-third of the shareholders
who have no personal interest in the transaction and are present at the meeting.
The transaction can be approved by shareholders without this one-third approval,
if the total shareholdings of those shareholders who have no personal interest
and voted against the transaction do not represent more than one percent of the
voting rights in the company.

In addition, a private placement of securities that will increase the
relative holdings of a shareholder that holds 5% or more of the company's
outstanding share capital or that will cause any person to become, as a result
of the issuance, a holder of more than five percent of the company's outstanding
share capital, requires approval by the board of directors and the shareholders
of the company. The Companies Law provides that an acquisition of shares in a
public company must be made by means of a tender offer if as a result of the
acquisition the purchaser would become a 25% shareholder of the company. This
rule does not apply if there is already another 25% shareholder of the company.
Similarly, the Companies Law provides that

an acquisition of shares in a public company must be made by means of a tender
offer if as a result of the acquisition the purchaser would become a 45%
shareholder of the company, unless there is a 50% shareholder of the company.
Regulations under the Companies Law provide that the Companies Law's tender
offer rules do not apply to a company whose shares are publicly traded outside
of Israel, if pursuant to the applicable foreign securities laws and stock
exchange rules there is a restriction on the acquisition of any level of control
of the company, or if the acquisition of any level of control of the company
requires the purchaser to make a tender offer to the public shareholders.

Indemnification of Directors and Officers

The Companies Law provides that an Israeli company cannot exculpate an
office holder from liability with respect to a breach of his duty of loyalty,
but may exculpate in advance an office holder from his liability to the company,
in whole or in part, with respect to a breach of his duty of care. Our Articles
of Association provide that, subject to any restrictions imposed by the
Companies Law, we may enter into a contract for the insurance of the liability
of any of our office holders with respect to:

o a breach of his duty of care to us or to another person;

o a breach of his duty of loyalty to us, provided that the office holder
acted in good faith and had reasonable cause to assume that his act
would not prejudice our interests; or

o a financial liability imposed upon him in favor of another person in
respect of an act performed by him in his capacity as an office
holder. In addition, we may indemnify an office holder against:

o a financial liability imposed on him in favor of another person by any
judgment, including a settlement or an arbitrator's award approved by
a court in respect of an act performed in his capacity as an office
holder; and

o reasonable litigation expenses, including attorneys' fees, expended by
such office holder or charged to him by a court, in proceedings we
institute against him or instituted on our behalf or by another
person, or in a criminal charge from which he was acquitted, all in
respect of an act performed in his capacity as an office holder.

These provisions are specifically limited in their scope by the Israeli
Companies Law, which provides that a company may not indemnify an office holder,
nor enter into an insurance contract that would provide coverage for any
monetary liability incurred as a result of any of the following:

o a breach by the office holder of his duty of loyalty unless the office
holder acted in good faith and had a reasonable basis to believe that
the act would not prejudice the company;

o a breach by the office holder of his duty of care if such breach was
done intentionally or in disregard of the circumstances of the breach
or its consequences;

o any act or omission done with the intent to derive an illegal personal
benefit; or

o any fine levied against the office holder as a result of a criminal
offense.

Under the Companies Law, our shareholders may amend our Articles of
Association to include either of the following provisions:

o Prospectively undertake to indemnify an office holder of the company,
provided that the undertaking is limited to types of events which our
board of directors deems to be anticipated and limited to an amount
determined by the board of directors to be reasonable under the
circumstances.

o Retroactively indemnify an office holder of the company.

In addition, pursuant to the Companies Law, indemnification of, and
procurement of insurance coverage for, our office holders must be approved by
our Audit Committee and our Board of Directors and, in specified circumstances,
by our shareholders.

On January 18, 2000, our shareholders agreed to indemnify our office
holders to the fullest extent permitted under the Companies Law. We have
obtained directors and officers liability insurance for the benefit of our
office holders.

Code of Ethics

We have adopted a Code of Business Conduct Ethics for Executive and
Financial Officers and which applies to all of our employees. The Code of
Business Conduct is publicly available on our website at www.radvision.com and
we will provide shareholders with a written copy upon request. If we make any
substantive amendments to the Code of Business Conduct or grant any waivers,
including any implicit waiver, from a provision of these codes to our chief
executive officer, chief financial officer or corporate controller, we will
disclose the nature of such amendment or waiver on our website.

any action by our board of directors which will alter or impair the rights of an
option holder requires the prior consent of that option holder.

Consultants Option Plan

Termination and Amendment

2000 Stock Option Plan

Our 2000 Employee Stock Option Plan, or the 2000 Plan, currently
authorizes the grant of options to purchase up to 4,865,839 ordinary shares.
Employees and consultants of our company and its subsidiaries are eligible to
participate in the 2000 Plan. The 2000 Plan also provides for the grant of
options equal in the amount of up to 4% of our share capital, on a fully diluted
basis, in each subsequent year following the year 2000 for issuance under the
2000 Stock Option Plan. An additional 894,945 ordinary shares were authorized
for grant in 2001 based on 4% of our share capital at December 31, 2000, an
additional 887,630 ordinary shares were authorized for grant in 2002 based on 4%
of our share capital at December 31, 2001, an additional 748,997 ordinary shares

future grants. Awards under the 2000 Plan may be granted in the form of
incentive stock options as provided in Section 422 of the U.S. Internal Revenue
Code of 1986, as amended, non-qualified stock options, options granted pursuant
to Section 102 of the Israeli Tax Ordinance and options granted pursuant to
Section 3.(9) of the Israeli Tax Ordinance.

Plan Administration

The option and compensation committee appointed by the Board of
Directors administers the 2000 Plan, subject to Board ratification. Subject to
the provisions of the 2000 Plan and applicable law, the option and compensation
committee has the authority to recommend to the Board:

o the persons to whom such awards are granted;

o the form, terms and conditions of the written stock option agreement
evidencing the option, including the type of option and the number of
shares to which it pertains, the option price, the option period and
its vesting schedule, and exercisability of the option in special
cases (such as death, retirement, disability and change of control);
and

o the form and provisions of the notice of exercise and payment of the
option.

Subject to the provisions of the 2000 Plan and applicable law, the Board
has the authority to:

o nominate a trustee for options issued under Section 102 of the Israeli
Tax Ordinance;

o adjust any or all of the number and type of shares that thereafter may
be made the subject of options, the number and type of shares subject
to outstanding options, and the grant or exercise price with respect
to any option, or, if deemed appropriate, make provision for a cash
payment to the holder of any outstanding option in order to prevent
dilution or enlargement of the benefits or potential benefits intended
to be made available under the 2000 Plan in the event of any dividend
or other distribution, recapitalization, stock split, reverse stock
split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase, or exchange of shares or other securities;

o interpret the provisions of the 2000 Plan; and

o prescribe, amend, and rescind rules and regulations relating to the
2000 Plan or any award thereunder as it may deem necessary or
advisable.

Neither the Board of Directors nor the option and compensation committee
may, without the consent of the optionee, alter or in any way impair the rights
of such optionee under any award previously granted. Neither the termination of
the 2000 Plan nor the change of control of our company, except to the extent
provided in the 2000 Plan, will affect any option previously granted.

The option price per share may not be less than 100% of the fair market
value of such share on the date of the award; provided, however, that in the
case of an award of an incentive stock option made to a 10% owner, the option
price per share may not be less than 110% of the fair market value (as such term
is defined in the 2000 Plan) of such share on the date of the award.

An option may not be exercisable after the expiration of ten (10) years
from the date of its award. No option may be exercised after the expiration of
its term. In the case of an award of incentive stock options made to a 10%
owner, such options may not be exercisable after the expiration of five (5)
years from its date of award.

Options are not assignable or transferable by the optionee, other than
by will or the laws of descent and distribution, and may be exercised during the
lifetime of the optionee only by the optionee or his or her guardian or legal
representative; provided, however, that during the optionee's lifetime, the
optionee may, with the consent of the option and compensation committee transfer
without consideration all or any portion of his options to members of the
optionee's immediate family (as defined in the 2000 Plan), a trust established
for the exclusive benefit of members of the optionee's immediate family, or a
limited liability company in which all members are members of the optionee's
immediate family.

options.

Item 12. Security Ownership of Certain Beneficial Owners and Management

The following table sets forth certain information, as of the date of

result, such shareholders may be able to exercise control with respect to the
election of directors.

Item 13. Certain Relationships and Related Transactions

The RAD-BYNET Group

Zohar Zisapel our chairman and Yehuda Zisapel, our former director and
chairman, are principal shareholders of our company. Individually or together,
they are also directors and principal shareholders of several other companies
which, together with us and the other subsidiaries and affiliates, are known as
the RAD-BYNET group. These corporations include but not limited to:

AB-NET Ltd. Ceragon Networks Ltd. RADWARE Ltd.
Axerra Networks Inc. RAD-BYNET Properties and Services RADCOM Ltd.
BYNET Data Communication Ltd. (1981) Ltd. RADWIN Ltd.
BYNET Electronics Ltd. Modules INC. RIT Technologies Ltd.
BYNET Properties Ltd. RAD Data Communication Ltd. Sanrad Inc.
BYNET SEMECH Outsourcing Ltd. RAD-OP Inc. SILICOM Ltd.
BYNET Systems Applications Ltd. E-BEAT Software and Internet WISAIR Inc.
BYNET Personal Computers Ltd. Services Ltd.

In addition to engaging in other businesses, members of the RAD-BYNET
group are actively engaged in designing, manufacturing, marketing and supporting
data communication products, none of which currently compete with our products.
Some of the products of members of the RAD-BYNET group are complementary to, and
may be used in connection with, our products.

Members of the RAD-BYNET group provide us with human resource and
administrative services, and we reimburse each company for its costs in
providing these services. The aggregate amount of these reimbursements was
approximately $54,000 and $28,000 in 2002 and 2003, respectively.

Agreement with Axerra Ltd. (formally named IP RAD Ltd)

In September 2000, we entered into an agreement to license our MGCP MG
software to Axerra Ltd., an affiliated company controlled by Yehuda and Zohar
Zisapel and a member of the RAD-BYNET group. The agreement, which was based on
our standard form, provides for an aggregate fee of $80,000. This fee includes
maintenance and support services for one year. In addition, the agreement
provides that Axerra has an option to extend the maintenance and support
services for additional annual periods.

Supply Arrangement

We purchase from RAD Data Communication components that we integrate
into our multimedia RADVISION products. The aggregate purchase price of these
components was approximately $133,000 for the year ended December 31, 2002 and
$23,000 for the year ended December 31, 2003.

We generally ascertain the market prices for goods and services that can
be obtained at arms' length from unaffiliated third parties before entering into
any transaction with a member of the RAD-BYNET group for those goods and
services. In addition, all of our transactions to date with members of the
RAD-BYNET group were approved unanimously by our shareholders. As a result, we
believe that the terms of the transactions in which we have engaged and are
currently engaged with other members of the RAD-BYNET group are beneficial to us
and no less favorable to us than terms which might be available to us from
unaffiliated third parties. Any future transactions and arrangements with
entities, including other members of the RAD-BYNET group, in which our office
holders have a personal interest will require approval by our audit committee,
our board of directors and, if applicable, our shareholders.

Voting Agreement

Upon the completion of the private placement which took place
contemporaneously with our March 2000 initial public offering, Siemens and some
of our existing shareholders, including our current chairman of the board, our
former chief executive officer, the Evergreen Group, Clal Venture Capital Fund
LP and Yehuda Zisapel, entered into a voting agreement. The voting agreement
provided that, in the election of our directors, the shareholders party to the
agreement will nominate and vote for a nominee of Siemens to serve as a director
and as many other nominees as the other shareholders party to the agreement
shall unanimously propose to serve as directors. However, the number of
directors that the other shareholders propose to serve as directors shall at a
minimum be equal to the number of directors which these shareholders appointed
to the board prior to March 2000. If all directors, except for one director,
decide that the continuation of a director on our board may damage our business
prospects, then the director shall be removed from our board.

The voting agreement expired in March 2003, but was subject to automatic
extensions for two additional one-year periods unless any of the parties to the
agreement provided notice to the other parties 60 days before the expiration
date of the then current term that such party wishes to terminate the agreement.
The voting agreement continues in effect at present and 3,837,554 ordinary
shares, representing approximately 19.6% of our outstanding shares, are
currently subject to the voting agreement.

Item 14. Principal Accountants Fees and Services

The following table sets forth, for each of the years indicated, the
fees paid to our independent public accountants and the percentage of each of
the fees out of the total amount paid to the accountants:

Year ended December 31,
----------------------------------------------------
2002 2003
----------------------- ------------------------
Services Rendered Fees Percentages(*) Fees Percentages(*)
--------------------- ------- -------------- ------- --------------
Audit (1)............ $50,000 49.0% $43,000 53.8%
Audit-related (2).... 5,000 4.9 5,000 6.2

Other (4)............ 30,000 29.4 - -
Total................ 102,000 100.0 80,000 100.0
--------------
(1) Audit fees consist of services that would normally be provided in
connection with statutory and regulatory filings or engagements,
including services that generally only the independent accountant can
reasonably provide.

(2) Audit-related fees relate to assurance and associated services that
traditionally are performed by the independent accountant, including
consultation concerning financial accounting and reporting standards.

(3) Tax fees relate to services performed by the tax division for tax
compliance, planning, and advice.

(4) Other fees include services related to valuation study and related
opinion.

Pre-Approval Policies and Procedures

The Audit Committee has adopted a policy and procedures for the
pre-approval of audit and non-audit services rendered by our independent public
accountants, Kost Forer Gabbay & Kasierer, a member of Ernest & Young Global.
The policy generally pre-approves certain specific services in the categories of
audit services, audit-related services, and tax services up to specified
amounts, and sets requirements for specific case-by-case pre-approval of
discrete projects, those which may have a material effect on our operations or
services over certain amounts. Pre-approval may be given as part of the Audit
Committee's approval of the scope of the engagement of our independent auditor
or on an individual basis. The pre-approval of services may be delegated to one
or more of the Audit Committee's members, but the decision must be presented to
the full Audit Committee at its next scheduled meeting. The policy prohibits
retention of the independent public accountants to perform the prohibited
non-audit functions defined in Section 201 of the Sarbanes-Oxley Act or the
rules of the SEC, and also considers whether proposed services are compatible
with the independence of the public accountants.

REPORT OF INDEPENDENT AUDITORS

To the Shareholders of

RADVISION LTD.

We have audited the accompanying consolidated balance sheets of Radvision
Ltd. (the "Company") and its subsidiaries as of December 31, 2002 and 2003, and
the related consolidated statements of operations, changes in shareholders'
equity and cash flows for each of the two years in the period ended December 31,
2003. Our audits also included the financial statement schedule listed in the
Index at Item 15(a). These financial statements and schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and schedule based on our audits. The
financial statements of Radvision Ltd. as of December 31, 2001 and for the year
then ended, were audited by other auditors who have ceased operations as a
foreign associated firm of the Securities and Exchange Commission Practice
Section of the American Institute of Certified Public Accountants and whose
report dated January 30, 2002, expressed an unqualified opinion on those
statements and schedule.

We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
the Company and its subsidiaries as of December 31, 2002 and 2003, and the
consolidated results of their operations and their cash flows for each of the
two years in the period ended December 31, 2003, in conformity with accounting
principles generally accepted in the United States. Also, in our opinion, the
related financial statement schedule, when considered in relation to the basic
financial statements and schedule taken as a whole, present fairly in all
material respects the information set forth therein.

cash flows for each of the three years in the period ended December 31, 2001.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

We conducted our audits in accordance with auditing standards generally accepted

made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of
RADVISION Ltd. and its subsidiaries as of December 31, 2000 and 2001, and the

RADVISION LTD. AND ITS SUBSIDIARIES
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
--------------------------------------------------------------------------------
U.S. dollars in thousands, except share and per share data

NOTE 1:- GENERAL

Radvision Ltd. ("the Company"), an Israeli corporation, designs,
develops and supplies products and technology that enable real-time
voice, video and data communications over packet networks, including
the Internet and other networks based on the Internet protocol.

The Company's products and technology are used by its customers to
develop systems that enable enterprises and service providers to use
packet networks for real-time IP ("Internet Protocol") communications.

Commencing in 2001, the Company operates under two reportable
segments: 1) the "networking" business unit (or "NBU"), which focuses
on a networking product and is responsible for developing networking
products for IP-centric voice, video and data conferencing services;
and 2) the "technology" business unit (or "TBU"), which focuses on
creating developer toolkits for the underlying IP communication
protocols and testing tools needed for real-time voice and video over
IP.

The Company has four wholly-owned subsidiaries: Radvision Inc., in the
United States, Radvision B.V., in the Netherlands, Radvision HK in
Hong Kong, and Radvision U.K. in the United Kingdom. The subsidiaries
are primarily engaged in the sale and marketing of the Company's
products and technology.

Revenues derived from the Company's largest customer in 2003,
represented 21% of total sales (see Note 10c).

NOTE 2:- SIGNIFICANT ACCOUNTING POLICIES

The consolidated financial statements are prepared according to United
States generally accepted accounting principles ("U.S. GAAP").

a. Use of estimates

The preparation of financial statements in conformity with
generally accepted accounting principles requires management to
make estimates and assumptions that affect the amounts reported
in the financial statements and accompanying notes. Actual
results could differ from those estimates.

b. Principles of consolidation:

The consolidated financial statements include the accounts of the
Company and its wholly-owned subsidiaries. Intercompany
transactions and balances have been eliminated upon
consolidation.

F-8

NOTE 2:- SIGNIFICANT ACCOUNTING POLICIES (Cont.)

c. Financial statements in U.S. dollars:

The Company and its subsidiaries' revenues are generated in U.S.
dollars ("dollar"). In addition, a significant portion of the
Company and its subsidiaries' costs is incurred in dollars. The
Company's management believes that the dollar is the primary
currency of the economic environment in which the Company and its
subsidiaries operate. Thus, the functional and reporting currency
of the Company and its subsidiaries is the dollar.

Accordingly, the Company and its subsidiaries' transactions and
balances denominated in dollars, are presented at their original
amounts. Non-dollar transactions and balances have been
remeasured into dollars in accordance with Statement of the
Financial Accounting Standard No. 52 "Foreign Currency
Translation" ("SFAS No.52"). All transaction gains and losses
from remeasurement of monetary balance sheet items denominated in
non-dollar currencies, are reflected in the statements of
operations as financial income or expenses, as appropriate, and
have not been material for all periods presented.

d. Cash equivalents:

Cash equivalents are short-term highly liquid investments that
are readily convertible to cash with maturities of three months
or less at the date acquired.

e. Marketable securities:

The Company accounts for investments in debt securities in
accordance with Statement of Financial Accounting Standard No.
115, "Accounting for Certain Investments in Debt and Equity
Securities" ("SFAS No. 115"). Management determines the
appropriate classification of its investments in debt and equity
securities at the time of purchase and reevaluates such
determinations at each balance sheet date. Debt securities are
classified as held-to-maturity when the Company has the positive
intent and ability to hold the securities to maturity and are
stated at amortized cost. The amortized cost of held-to-maturity
securities is adjusted for amortization of premiums and accretion
of discounts to maturity. Such amortization, accretion and
decline in value judged to be other than temporary and interest
are included in financial income, net.

f. Short-term bank deposits:

Short-term bank deposits are deposits with maturities of more
than three months but less than one year. The deposits are in
dollars and bear interest at an average rate of 3.75% at December
31, 2003. The short-term deposits are presented at their cost,
including accrued interest.

g. Long-term bank deposits:

Bank deposits with maturities of more than one year are presented
at their cost plus accrued interest. The deposits are in dollars
and bear interest at an average rate of 2.25% at December 31,
2003.

F-9

NOTE 2:- SIGNIFICANT ACCOUNTING POLICIES (Cont.)

h. Inventories:

Inventories are stated at the lower of cost or market value.

Inventory write-offs and write-down provisions are provided to
cover risks arising from slow-moving items or technological
obsolescence. The Company and its subsidiaries periodically
evaluate the quantities on hand, relative to current and
historical selling prices, and historical and projected sales
volume and aging inventory. Based on this evaluation, provisions
are made when required to write inventory down to its market
prices. As a result of adjusted forecast of revenues for the
years 2003 and 2004, and the decision to discontinue selling
certain products, the Company and its subsidiaries wrote off
excess inventories in order to adjust the inventory level to the
new revenue expectations. The Company's provision for slow-moving
items or technological obsolescence was $ 2,914, $ 3,310 and $
2,452 as of December 31, 2001, 2002 and 2003, respectively.

Cost is determined as follows:

Raw materials - using the average cost method.
Work-in-progress - represents the cost of subcontractors.
Finished products - on the basis of subcontractors' costs, with
the addition of raw materials.

i. Property and equipment:

Property and equipment are stated at cost, net of accumulated
depreciation. Depreciation is calculated using the straight-line
method over the estimated useful lives of the assets, at the
following annual rates:

%
--------------------------
Computers and peripheral equipment 15-33
Office furniture and equipment 7-15
Motor vehicles 15
Leasehold improvements Over the term of the lease

j. Impairment of Long-Lived Assets:

The Company and the subsidiaries' long-lived assets are reviewed
for impairment in accordance with Statement of Financial
Accounting Standard No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets" ("SFAS No. 144") whenever events
or changes in circumstances indicate that the carrying amount of
an asset may not be recoverable. Recoverability of assets to be
held and used is measured by a comparison of the carrying amount
of an asset to the future undiscounted cash flows expected to be
generated by the assets. If such assets are considered to be
impaired, the impairment to be recognized is measured by the
amount by which the carrying amount of the assets exceeds the
fair value of the assets. As of December 31, 2003, no impairment
losses have been identified.

F-10

NOTE 2:- SIGNIFICANT ACCOUNTING POLICIES (Cont.)

k. Severance pay:

The Company's liability for severance pay is calculated pursuant
to Israeli severance pay law based on the most recent salary of
the employees multiplied by the number of years of employment, as
of the balance sheet date. Employees are entitled to one month's
salary for each year of employment or a portion thereof. The
Company's liability for all of its employees is fully provided by
monthly deposits for insurance policies and by an accrual. The
value of these policies is recorded as an asset in the Company's
balance sheet.

The deposited funds include profits accumulated up to the balance
sheet date. The deposited funds may be withdrawn only upon the
fulfillment of the obligation pursuant to Israeli severance pay
law or labor agreements. The value of the deposited funds is
based on the cash surrendered value of the policies and includes
immaterial profits.

Severance pay expenses for the years ended December 31, 2001,
2002 and 2003, amounted to approximately $ 279, $ 748 and $ 390,
respectively.

l. Revenue recognition:

The Company and its subsidiaries generate revenues mainly from:
1) sales of systems; 2) licensing the rights to use its software
products royalty income; 3) maintenance and support; and 4)
customization projects. The Company and its subsidiaries sell
their hardware products through OEMs, system integrators and
value added resellers, all of whom are considered end-users.

Software licensing, royalties and other revenues:

The Company accounts for software sales in accordance with
Statement of Position 97-2,"Software Revenue Recognition," ("SOP
97-2"). SOP 97-2 generally requires revenue earned on software
arrangements involving multiple elements to be allocated to each
element based on the relative fair value of the elements. In
addition the Company has adopted Statement of Position 98-9,
"Modification of SOP 97-2, Software Revenue Recognition with
Respect to Certain Transactions", ("SOP 98-9"). SOP 98-9 requires
that revenue be recognized under the "residual method" when
vendor specific objective evidence (VSOE) of fair value exists
for all undelivered elements, VSOE does not exist for all of the
delivered elements and all other SOP 97-2 revenue recognition
criteria are met. Under the residual method any discount in the
arrangement is allocated to the delivered element.

Revenue from license fees is recognized when persuasive evidence
of an agreement exists, delivery of the product has occurred, no
significant obligations with regard to implementation remain, the
fee is fixed or determinable and collectibility is probable.

Maintenance and support revenue included in multiple element
arrangements is deferred and recognized on a straight-line basis
over the term of the maintenance and support agreement. The VSOE
of fair value of the undelivered elements (maintenance and
support fees) is determined based on the price charged for the
undelivered element when sold separately.

F-11

NOTE 2:- SIGNIFICANT ACCOUNTING POLICIES (Cont.)

In agreements for which the customer requires a 30-day acceptance
provision, the Company and its subsidiaries defer the recognition
of revenues until the receipt of the acceptance confirmation.

Certain royalty agreements provide for per unit royalties to be
paid to the Company based on the shipments by customers of units
containing the Company's products. Revenues under such agreements
are recognized at the time of shipments by the customers as they
are reported to the Company by these customers on cash basis.
Non-refundable payments on account of future royalties from
similar agreements are recognized upon payment, provided that no
future obligation exists.

Revenues from professional services are recognized based on
Statement of Position No. 81-1 "Accounting for Performance of
Construction - Type and Certain Production - Type Contracts"
("SOP 81-1"), using contract accounting on a percentage of
completion method, based on completion of agreed-upon milestones
and in accordance with the "Output Method" or based on the time
and material basis. After delivery of milestone, if uncertainty
exists about customer acceptance, revenue is not recognized until
acceptance. Provisions for estimated losses on uncompleted
contracts are recognized in the period in which the likelihood of
such losses is determined. As of December 31, 2003, no such
estimated losses were identified.

Deferred revenue includes unearned amounts received under
maintenance and support contracts, and amounts received from
customers but not recognized as revenues.

The Company offers a one-year warranty for all of its products.
The specific terms and conditions of those warranties vary
depending upon the product sold and country in which the Company
does business. For products sold in the United States, the
Company provides a basic limited warranty, including parts and
labor, for all products for a period of one year. The Company
estimates the costs that may be incurred under its basic limited
warranty and records a liability in the amount of such costs at
the time product revenue is recognized. Factors that affect the
Company's warranty liability include the number of installed
units, historical and anticipated rates of warranty claims, and
cost per claim. The Company periodically assesses the adequacy of
its recorded warranty liabilities and adjusts the amounts as
necessary.

Sales of system:

Revenues from product sales are recognized in accordance with
Staff Accounting Bulletin No.104, "Revenue Recognition" ("SAB
No.104"), when delivery has occurred, persuasive evidence of an
agreement exists, the vendor's fee is fixed or determinable, no
further obligation exists and collectibility is probable.

F-12

NOTE 2:- SIGNIFICANT ACCOUNTING POLICIES (Cont.)

The Company and its subsidiaries generally do not grant a right
of return to its customers. When returns are expected and
estimated, the Company defers revenue until the probability for
such returns expires, at which time revenue is recognized
provided that all other revenue recognition criteria are met. The
Company maintains provision for product returns; based on its
experience in accordance with Statement of Financial Accounting
Standard No. 48, "Revenue Recognition When Right of Return
Exists". The provision has been immaterial for the years ended
December 31, 2001, 2002 and 2003.

In November 2002, the Emerging Issues Task Force ("EITF") of the
FASB reached a consensus on EITF Issue No. 00-21, "Revenue
Arrangements with Multiple Deliverables" related to the timing of
revenue recognition for arrangements in which goods or services
or both are delivered separately in a bundled sales arrangement.
The consensus requires that when the deliverables included in
this type of arrangement meet certain criteria they should be
accounted for separately. This may result in a difference in the
timing of revenue recognition but will not result in a change in
the total amount of revenue recognized over the life of the
arrangement. The allocation of revenue to the separate
deliverables is based on the relative fair value of each item in
a bundled sales arrangement. If the fair value is not available
for the delivered items, the residual method must be used. This
method requires that the amount allocated for the undelivered
items in the arrangement be recorded at their full fair value.
This results in the discount, if any, being allocated to the
delivered items. This consensus is effective prospectively for
arrangements entered into in fiscal periods beginning after June
15, 2003. The adoption of EITF Issue No. 00-21 did not have a
material impact upon the Company's financial position, cash flows
or results of operations.

m. Research and development costs:

Research and development costs are charged to the statement of
operations, as incurred. Statement of Financial Accounting
Standard No. 86 "Accounting for the Costs of Computer Software to
be Sold, Leased or Otherwise Marketed", requires capitalization
of certain software development costs subsequent to the
establishment of technological feasibility.

Based on the Company's product development process, technological
feasibility is established upon completion of a working model.
Costs incurred by the Company between completion of the working
models and the point at which the products are ready for general
release have been insignificant. Therefore, all research and
development costs have been expensed.

n. Non-royalties bearing grants:

The Company received grants from the Israel U.S Binational
Industrial Research and Development Foundation and the Chief
Scientist Office (see Note 7a). These grants are recognized at
the time the Company is entitled to such grants on the basis of
the costs incurred and included as a deduction of research and
development costs.

F-13

NOTE 2:- SIGNIFICANT ACCOUNTING POLICIES (Cont.)

o. Income taxes:

The Company and its subsidiaries account for income taxes in
accordance with Statement of Financial Accounting Standards No.
109, "Accounting for Income Taxes" ("SFAS No. 109"). This
Statement prescribes the use of the liability method whereby
deferred tax assets and liability account balances are determined
based on differences between financial reporting and tax bases of
assets and liabilities and are measured using the enacted tax
rates and laws that will be in effect when the differences are
expected to reverse. The Company and its subsidiaries provide a
valuation allowance, if necessary, to reduce deferred tax assets
to their estimated realizable value.

p. Fair value of financial instruments:

The Company and its subsidiaries, in estimating the fair value of
their financial instruments used the following methods and
assumptions for disclosures of financial instruments:

The carrying amount reported in the balance sheet for cash and
cash equivalents, short-term bank deposits, trade receivables and
trade payables approximate their fair values due to the
short-term maturities of such instruments.

The fair value of held to maturity marketable securities is based
on amortized cost, which does not differ significantly from the
quoted market prices (see Note 3).

q. Accounting for stock-based compensation:

The Company accounts for stock-based compensation in accordance
with the provisions of Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" (APB No. 25) and
FASB interpretation No. 44, "Accounting for Certain Transactions
Involving Stock Compensation" ("FIN No. 44") in accounting for
its employee stock options. Under APB No. 25, when the exercise
price of the employee's options equals or is higher than the
market price of the underlying Company share on the date of
grant, no compensation expense is recognized.

The Company adopted the disclosure provisions of Financial
Accounting Standards Board Statement No. 148, "Accounting for
Stock-Based Compensation - Transition and Disclosure" ("SFAS No.
148"), which amended certain provisions of Statement of Financial
Accounting Standard No.123 "Accounting for Stock-Based
Compensation" ("SFAS No. 123") to provide alternative methods of
transition for an entity that voluntarily changes to the fair
value based method of accounting for stock-based employee
compensation, effective as of the beginning of the fiscal year.
The Company continues to apply the provisions of APB No. 25, in
accounting for stock-based compensation.

Pro forma information regarding the Company's net income (loss)
and net earnings (loss) per share is required by SFAS No. 123 and
has been determined as if the Company had accounted for its
employee stock options under the fair value method prescribed by
SFAS No. 123.

F-14

NOTE 2:- SIGNIFICANT ACCOUNTING POLICIES (Cont.)

The fair value of these options is amortized over their vesting
period and estimated at the date of grant using a Black-Scholes
multiple option pricing model with the following weighted average
assumptions; risk-free interest rates of 2.5%, 3% and 2.37% for
2001, 2002 and 2003, respectively; a dividend yield of 0.0% for
each of those years; a volatility factor of the expected market
price of the Company's Ordinary shares of 0.98 for 2001, 0.48 for
2002 and 0.771 for 2003; and a weighted-average expected life of
the option of 2.9 years for 2001, 2002 and 2003.

The weighted average fair values on the grant date, for the years
ended December 31, 2001, 2002 and 2003 amounted to $ 3.29, $ 2.03
and $ 4.25, respectively.

The following table illustrates the effect on net income (loss)
and net earnings (loss) per share, assuming that the Company had
applied the fair value recognition provision of SFAS No. 123 on
its stock-based employee compensation:

Year ended December 31,

r. Concentration of credit risk:

Financial instruments that potentially subject the Company and
its subsidiaries to concentrations of credit risk consist
principally of cash and cash equivalents, marketable securities,
short-term bank deposits, trade receivables and long-term bank
deposits.

F-15

NOTE 2:- SIGNIFICANT ACCOUNTING POLICIES (Cont.)

The majority of the Company's cash and cash equivalents,
short-term and long-term bank deposits are invested in dollar
investments with major banks in Israel and the U.S. Such cash and
cash equivalents, short-term and long-term bank deposits in the
United States may be in excess of insured limits and are not
insured in other jurisdictions. However, management believes that
the financial institutions that hold the Company's investments
are financially sound and accordingly, minimal credit risk exists
with respect to these investments.

The marketable securities of the Company and its subsidiaries
include investments in debentures of U.S corporations, and state
and political subdivisions. Management believes that the
portfolio is well diversified, and accordingly, minimal credit
risk exists with respect to these marketable securities.

The trade receivables of the Company and its subsidiaries related
to NBU business are derived from sales to large and solid
organizations located mainly in North America, Europe, Far East
and Israel. The Company and its subsidiaries perform ongoing
credit evaluations of their customers and to date have not
experienced any material losses. An allowance for doubtful
accounts is determined with respect to those amounts that the
Company and its subsidiaries have determined to be doubtful of
collection and by a general reserve. In certain circumstances,
the Company and its subsidiaries may require letters of credit,
other collateral or additional guarantees.

The Company and its subsidiaries' trade receivables related to
TBU business are derived from sales to emerging companies located
mainly in North America, Europe, the Far East and Israel. The
Company and its subsidiaries perform ongoing credit evaluations
of their customers and when uncertainty of collectibility exists,
the Company and its subsidiaries defer revenues until such
uncertainty expires.

As of December 31, 2003, the current balance of one customer
accounted for 21.7% of the Company's trade receivables for a
total of approximately $ 1,884.

The Company and its subsidiaries do not have significant
off-balance-sheet concentration of credit risk, such as foreign
exchange contracts, options contracts or other foreign hedging
arrangements.

s. Basic net earnings (loss) per share:

Basic net earnings (loss) per share is computed based on the
weighted average number of Ordinary shares outstanding during the
year. For the same periods, diluted net earnings (loss) per share
further includes the effect of dilutive stock options outstanding
during the year, all in accordance with SFAS No. 128, "Earnings
per Share".

Options outstanding to purchase approximately 2,226,906 and
1,202,258 Ordinary shares for the years ended December 31, 2002
and 2003, respectively, were not included in the computation of
diluted net earnings per share, because option exercise price
were greater than the average market price of the Ordinary shares
and therefore their inclusion would have been anti-dilutive.

NOTE 7:- COMMITMENTS AND CONTINGENCIES

a. In connection with its research and development, the Company
received and accrued participation payments from the Israel U.S.
Binational Industrial Research and Development Foundation
(BIRD-F), in the total amount of approximately $188. In return
for the participation, the Company is committed to pay royalties
at a rate of 2.5% of proceeds from the first year's sales and 5%
of the proceeds from the succeeding years' sales, up to the
amount of the grant. Once the amount of the grant has been
repaid, royalties will be payable at the rate of 2.5% of
proceeds, until additional royalties equal to one half of the
grant amount have been repaid. The Company's total commitment for
royalties payable with respect to future sales, based on BIRD-F
participations received or accrued, net of royalties paid or
accrued, totaled approximately $ 276 as of December 31, 2002 and
2003. Royalties paid or accrued to the BIRD-F amounted to $ 0
during the year 2003.

b. The Company and its subsidiaries operate from leased premises in
Israel, United States, China, the United Kingdom and Hong Kong.
The leases expire through October 2005 (some with renewal
options). The Company rents their vehicles under operating lease
agreements that expire on various dates, the latest of which is
in 2005.

Annual minimum future rental payments due under the above
agreements, at the exchange rate in effect on December 31, 2003,
are approximately as follows:

2004 $ 1,788
2005 869
-------------

$ 2,657
=============

For the years ended December 31, 2001, 2002 and 2003, rent
expenses were $ 1,424, $ 1,556 and $ 1,608, respectively.

F-18

NOTE 7:- COMMITMENTS AND CONTINGENCIES (Cont.)

c. The Company is committed to pay royalties to two third parties
for the integration of these third parties' technologies into the
Company's products. Royalties are payable based on the sales
volume of these products, as long as the Company uses these
technologies.

The rates of royalties to one of the third parties are based on a
fixed amount per product sold by the Company ranging from $ 1.00
to $ 5.00 (in dollars) per unit sold.

The agreements pursuant to which the royalties are payable have
no expiration date. Annual minimum future royalty payments are
approximately as follows as of December 31, 2003:

2004 $ 25
==============

The Company paid royalties in the amount of $ 25 in 2003.

d. In 1998, a third party sent correspondence to the Company's
affiliate alleging that some products manufactured by the Company
infringe upon patents held by the third party and offered to
license these patents to the Company. In subsequent
correspondence, the Company's affiliate requested that the third
party specifically substantiate each allegation of infringement
before the Company's affiliate would be prepared to enter into
any licensing arrangements. The Company does not believe that
these allegations will have a material adverse effect upon its
business, financial position, results of operations or liquidity.
The Company's affiliate has received further correspondence from
the third party, in which the third party has, among other
things, reiterated its claims. The Company's affiliate does not
believe the third party has substantiated its claims and has
communicated this belief to the third party. The Company's
affiliate has advised the Company that the alleged infringement
claims are unresolved. The Company's management is unable to
determine with any certainty the ultimate outcome of the
allegations, and its effect on the Company's business, results of
operations and financial condition.

e. In January 2001, the Company entered into an agreement with

any. In December 2003, the parties proceeded to binding
arbitration. The presiding arbitrator issued his final ruling on
February 12, 2004 stating the amount owed by the Company is $
400. The Company accrued sufficient funds for the outcome of this

NOTE 8:- SHAREHOLDERS' EQUITY

The Ordinary shares of the Company are traded on the NASDAQ National
Market.

Since October 20, 2002, the Ordinary shares of the Company have also
been traded on the Tel Aviv Stock Exchange.

The Ordinary shares confer upon their holders the right to receive
notice to participate and vote in general meetings of the Company, and
the right to receive dividends, if declared.

a. The Company had an authorized share capital of 15,530 deferred
shares of par value NIS 0.1 each. The deferred shares conferred
no rights or privileges on their holders, except for the right to
receive, upon dissolution or liquidation, the par value of the
deferred shares. In October 2002, special shareholders meeting
approved a conversion of the deferred shares to Ordinary shares.

b. In February 2001, the Company announced that its Board of
Directors authorized the purchase of up to 10% of its outstanding
Ordinary shares in the open market, from time to time, at
prevailing market prices. No time limit was given with respect to
the duration of the share purchase program.

On August 28, 2002, the Board of Directors authorized an
additional purchase of up to $ 10,000 or 2,000,000 of the
Company's outstanding Ordinary shares in the open market.

As of December 31, 2003, the remaining amount of purchased
Ordinary shares was 807,196, at a cost of $ 5,075.

Such repurchases of Ordinary shares are accounted for as treasury
stock and result in a reduction of stockholders' equity. When
Treasury shares are reissued, the Company accounts for the
re-issuance in accordance with Accounting Principles Board No. 6
"Status of Accounting Research Bulletins" ("APB No. 6") and
charges the excess of the repurchase cost over issuance price
using the weighted average method to retained earnings. In case
the repurchase cost is lower than the issuance price, the Company
credits the difference to additional paid-in capital.

c. The Company adopted a key employee share incentive plans which
provides for the grant by the Company of option awards to
purchase up to an aggregate of 7,484,072 Ordinary shares to
officers, employees, directors and consultants of the Company and
its subsidiaries and affiliates. The options vest ratably over
vesting periods ranging from three to five years. The options
expire 5 to 10 years from the date of issuance. The incentive
plan provides for the grant of options equal in the amount of up
to 4% of the Company's share capital on a diluted basis.

On April 8, 2003, the Company authorized the issuance of up to
748,997 additional Ordinary shares, of NIS 0.1 par value per
share.

On December 22, 2003, the Board of Directors authorized the
issuance of up to 250,000 additional shares to qualify for future
grants.

F-20

NOTE 8:- SHAREHOLDERS' EQUITY (Cont.)

As of December 31, 2003, 50,098 shares qualify for future grant.
Options that are cancelled or forfeited before expiration become
available for future grant.

NOTE 14:- TAXES ON INCOME

a. Tax benefits under the Law for the Encouragement of Capital
Investment, 1959 ("the Law"):

The Company's investment program totaling $ 122 has been granted
Approved Enterprise status under the Law for Encouragement of
Capital Investments, 1959. In addition, the Company was granted
Approved Enterprise status for an expansion of a previous program
totaling $ 459. The Company has chosen to enjoy "Alternative plan
benefits", according to which the Company is entitled to a tax
benefit period of seven years, on income derived from these
programs, as follows: a full income tax exemption for the first
two years and a reduced income tax rate of 25% (instead of the
regular rate of 36%) for the remaining five year period. If
foreign shareholdings in the Company exceed 25%, the period for
which the Company is entitled to a reduced income tax is extended
to eight years, and subject to corporate taxes at the reduced
rate of 10%-25% (depending on the level of non-Israeli
investments in the Company).

F-25

RADVISION LTD. AND ITS SUBSIDIARIES

NOTE 14:- TAXES ON INCOME (Cont.)

The period of tax benefits detailed above is subject to limits of
12 years from the year of commencement of production, or 14 years
from the date of granting the approval, whichever is earlier.
Given the aforementioned conditions, under the first expansion
program, the period of benefits for the production facilities,
which has not yet commenced, will terminate in the year 2010, and
under the second expansion program the period of benefits for the
production, which has yet commenced, will terminate in the year
2012.

As the Company currently has no taxable income, the benefits have
not yet commenced for all programs since inception.

In addition, in July 2003, the Company received a letter of
approval for a second expansion of an approved plan. The approved
investment amounted to $ 180, which is to be carried out by July
27, 2005.

The tax-exempt income attributable to the "Approved Enterprise"
can be distributed to shareholders without subjecting the Company
to taxes only upon the complete liquidation of the Company. If
these retained tax-exempt profits are distributed in a manner
other than in the complete liquidation of the Company they would
be taxed at the corporate tax rate applicable to such profits as
if the Company had not elected the alternative system of
benefits, currently between 25% for an "Approved Enterprise". As
of December 31, 2003, the accumulated deficit of the Company does
not include tax-exempt profits earned by the Company's "Approved
Enterprise".

The benefits from the Company's approved enterprise programs are
dependent upon the Company fulfilling the conditions stipulated
by the Law for Encouragement of Capital Investments, 1959 and the
regulations published under this law, as well as the criteria in
the approval for the specific investment in the Company's
"Approved Enterprise" programs. If the Company does not comply
with these conditions, the tax benefits may be canceled, and the
Company may be required to refund the amount of the canceled
benefits, with the addition of linkage differences and interest.
As of the date of these financial statements, the Company's
management believes that it has complied with these conditions.

By virtue of this law, the Company is entitled to claim
accelerated depreciation on equipment used by the "Approved
Enterprise" during five tax years.

Income from sources other than the "Approved Enterprise" during
the benefit period will be subject to tax at the regular
corporate tax rate of 36%.

b. Tax reform:

On July 24, 2002, Amendment 132 to the Israeli Income Tax
Ordinance ("the Amendment") was approved by the Israeli
parliament and came into effect on January 1, 2003. The principal
objectives of the Amendment were to broaden the categories of
taxable income and to reduce the tax rates imposed on the
employees' income.

F-26

RADVISION LTD. AND ITS SUBSIDIARIES
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
--------------------------------------------------------------------------------
U.S. dollars in thousands

NOTE 14:- TAXES ON INCOME (Cont.)

The material consequences of the Amendment applicable to the
Company include, among other things, imposing a tax upon all
income of Israeli residents, individuals and corporations,
regardless of the territorial source of income and certain
modifications in the qualified taxation tracks of employee stock
options.

c. Measurement of taxable income under the Income Tax (Inflationary
Adjustments) Law, 1985:

Results for tax purposes are measured and reflected in real terms
in accordance with the change in the Israeli Consumer Price Index
("CPI"). As explained in Note 2c the consolidated financial
statements are presented in dollars. The differences between the
change in the Israeli CPI and in the NIS/U.S. dollar exchange
rate causes a difference between taxable income or loss and the
income or loss before taxes reflected in the consolidated
financial statements. In accordance with paragraph 9(f) of SFAS
No. 109, the Company has not provided deferred income taxes on
this difference between the reporting currency and the tax bases
of assets and liabilities.

d. Tax benefits under Israel's Law for the Encouragement of Industry
(Taxation), 1969:

The Company is an "industrial company", as defined by the law for
the Encouragement of Industry (Taxes), 1969, and as such, is
entitled to claim public issuance expenses, and accelerated
depreciation on equipment used by the "Approved Enterprise", over
five tax years.

e. As of December 31, 2003, the Company's net operating loss
carryforwards for tax purposes amounted to approximately $
16,500. These net operating losses may be carried forward
indefinitely and offset against future taxable income. The
Company expects that during the period in which these tax losses
are utilized its income would be substantially tax-exempt.
Accordingly, the income tax rate of the Company during the
tax-exempt period will be zero, and there will be no tax benefit
available from these losses and no deferred tax asset has been
included in these financial statements. Deferred taxes in respect
of other temporary differences are immaterial.

f. The U.S. subsidiary's carryforward tax losses through December
31, 2003, amounted to approximately $ 14,000. These losses are
available to offset any future U.S. taxable income of the U.S.
subsidiary and will expire in the years 2010 through 2022. In
light of the subsidiary's recent history of operating losses, the
Company has recorded a valuation allowance for all its deferred
tax assets.

Utilization of U.S. net operating losses may be subject to
substantial annual limitation due to the "change in ownership"
provisions of the Internal Revenue Code of 1986 and similar state
provisions. The annual limitations may result in the expiration
of net operating losses before utilization.

g. Deferred income taxes:

Deferred income taxes reflect the net tax effects of net
operating loss carryforward between the carrying amounts of
assets and liabilities for financial reporting purposes and
amounts used for income tax purposes. Significant components of
the Company's deferred tax assets resulting from tax loss
carryforward are as follows:

December 31,

-------------- --------------

Net operating loss carryforward $ 9,540 $ 11,540
Valuation allowance (9,540) (11,540)
-------------- --------------
$ - $ -
============== ==============

The Company and its subsidiaries provided valuation allowances in
respect of deferred tax assets resulting from tax loss
carryforwards and other temporary differences. Management
currently believes that it is more likely than not that the
deferred tax regarding the loss carryforwards and other temporary
differences will not be realized. The change in the valuation
allowance as of December 31, 2003 was $ 2,000.

h. The Company's total income (loss) before provision for income
taxes is as follows:
