               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.

               The  Company  operates  under  two  reportable  segments:  1) the

               voice and video over IP.

               The Company has six wholly-owned subsidiaries:  Radvision Inc. in

               holding company.

               Following  a bidding  process  held  under the  supervision  of a
               United   States    Bankruptcy   Court,   the   Company   acquired
               substantially  all of the assets of First Virtual  Communications
               and its wholly-owned subsidiary, CUseeMe Networks, Inc. on an "as

               provided  for by a  cash  purchase  price  of $  7,496  including
               transaction costs.

               The  acquisition  was  accounted  under  the  purchase  method of
               accounting. Accordingly, all assets and liabilities were recorded
               at their  estimated  market values as of the date  acquired,  and
               results  of  FVC's   operations   have  been   included   in  the

          c.   Restatement of previously-issued financial statements:
               ------------------------------------------------------

               As described in Note 13 to the annual financial statements and in
               Form 20-F for the year ended  December 31, 2004, in January 2001,
               the Company  entered into a lease  agreement with related parties
               for a period of five years. Subsequently, the Company surrendered
               the property  before  inception of the lease.  The parties to the
               lease  agreement  disputed  the extent of damages  caused by this
               action  and  agreed  to  proceed  to  binding  arbitration.   The
               presiding  arbitrator  issued his ruling on  February  12,  2004,
               stating  the amount the Company  owed was $ 400.  The Company had
               previously  accrued  a  liability  of $1,461  in  respect  of the
               aforementioned dispute.

               Prior to the issuance of the arbitration  ruling, the Company had
               announced its 2003 financial  results,  but had not yet filed its
               annual report on Form10-K for the year ended December 31, 2003.

               In the 2003 audited financial  statements the arbitration  ruling
               was  treated  as a "Type  II" event as  defined  in AU 560 of the
               PCAOB  auditing  standards  ("AU  560")  and,   accordingly  full
               disclosure  concerning the event was provided in the 2003 audited
               financial  statements  while no  revision  was made to the $1,461
               accrual.

               In the process of preparing the financial statements for the year
               ended  December 31, 2004, the  accounting  treatment  relating to
               this event was  reconsidered  and  consequently  it was concluded
               that  the   arbitration   ruling  issued  on  February  14,  2004
               represents a "Type I" event  according to AU 560, due to the fact
               that the above ruling,  which became available  subsequent to the
               period  covered  by the 2003  financial  statements,  but  before
               issuance  of  such  financial  statements,   provided  additional
               evidence with respect to conditions  that existed on December 31,
               2003 and affected  estimates used in preparing the 2003 financial
               statements. Consequently, the estimated provision relating to the
               aforementioned  dispute is being  revised  from $1,461 to $400 in
               the 2003  fiscal  year and the  financial  statements  are  being
               restated accordingly.

               As  a  result  of  this   restatement,   the   Company   recorded
               restructuring  income of $1,061 in the year  ended  December  31,
               2003,  resulting in increased  net income and  decreased  accrued
               expenses in that amount.

          d.   New accounting pronouncements:

               In December 2004, the Financial Accounting Standards Board issued
               Statement  of  Financial   Accounting   Standards   No.   123(R),
               "Share-Based Payment" ("Statement No. 123R"), which is a revision
               of Statement  No. 123 and  supersedes  APB No. 25. The  Statement
               addresses the accounting for  transactions in which an enterprise
               receives employee services in exchange for (a) equity instruments
               of the enterprise or (b)  liabilities  that are based on the fair
               value  of the  enterprise's  equity  instruments  or that  may be
               settled by the issuance of such equity instruments. The Statement
               eliminates  the ability to account for  share-based  compensation
               transactions  using  APB No.  25,  and  generally  would  require
               instead that such  transactions  be  accounted  for using a grant
               date fair-value  based method.  Companies will now be required to
               recognize an expense for compensation cost related to share-based
               payment  arrangements  including stock options and employee stock
               purchase  plans.  In March  2005,  the  Securities  and  Exchange
               Commission  ("SEC")  issued  Staff  Accounting  Bulletin No. 107,
               "Share-Based   Payment"  ("SAB  107"),   which  provided  further
               clarification  on the  implementation  of Statement  No. 123R. In
               April 2005, the SEC announced a deferral of the effective date of
               Statement No. 123R for calendar year  companies  until January 1,
               2006.  It is expected  that the new rules of  Statement  No. 123R
               will be applied on a modified  perspective  basis. The Company is
               currently   evaluating   option   valuation   methodologies   and
               assumptions  in light of Statement No. 123R and SAB 107.  Current
               estimates  of option  values using the  Black-Scholes  method (as
               shown  above) may not be  indicative  of results  from  valuation
               methodologies ultimately adopted by the Company.

NOTE 2:- SIGNIFICANT ACCOUNTING POLICIES

          The significant  accounting  policies  applied in the annual financial
          statements  of  the  Company  as of  December  31,  2004  are  applied
          consistently in these financial statements.

          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.   For  further  information,  refer to the  consolidated  financial
               statements as of December 31, 2004.

          c.   Accounting for stock-based compensation:

               The  Company has elected to follow  Accounting  Principles  Board
               Opinion No. 25,  "Accounting for Stock Issued to Employees" ("APB
               No.  25") and FASB No.  Interpretation  No. 44,  "Accounting  for
               Certain Transactions Involving Stock Compensation" ("FIN No. 44")
               in accounting for its employee stock option plans.  Under APB No.
               25, when the exercise  price of the  Company's  stock  options is
               less than the market price of the  underlying  shares on the date
               of grant, compensation expense is recognized.

               Under  Statement  of  Financial   Accounting  Standard  No.  123,
               "Accounting for Stock-Based  Compensation  ("SFAS No. 123"),  pro
               forma information regarding net income and net earnings per share
               is  required,  and has  been  determined  as if the  Company  had
               accounted  for its employee  stock  options  under the fair value
               method of SFAS No.  123.  The fair  value for  these  options  is
               amortized  over their vesting period and estimated at the date of
               grant  using a Black - Scholes  Option  Valuation  Model with the
               following weighted-average assumptions for the three months ended
               March 31, 2005 and 2004:

2.   Management's  Discussion and Analysis of Financial Condition and Results of
     Operations
     ---------------------------------------------------------------------------

This information should be read in conjunction with the condensed consolidated
financial statements and notes included in Condensed Consolidated Financial
Statements for the Quarterly Period ended March 31, 2005 above and the audited
financial statements and notes thereto and Item 5. Operating And Financial
Review And Prospects contained in our 2004 Annual Report on Form 20-F. The

Overview

We are 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 Internet Protocol, or IP,
and 3G networks. We have approximately 420 customers worldwide including
Alcatel, Cisco, FastWeb, NTT/DoCoMo, Philips, Panasonic, Samsung, Shanghai Bell,
Siemens, Sony and Tandberg. 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 our multimedia communication platforms and software
development solutions.

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

                                       14






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. We are currently in the
process of separating the NBU into two separate business units. The Enterprise
Business Unit will focus on the sale of multimedia communication and
videoconferencing network solutions for enterprise customers, including desktop
applications. The Service Providers Business Unit will provide products and
solutions for service providers, both 3G wireless and wireline, to allow these
customers to provide high scale, large capacity multimedia communication and
video conferencing within their chosen environment.

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
with integrating 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.

Following a bidding process held under the supervision of a United States
Bankruptcy Court, we acquired substantially all of the assets of First Virtual
Communications, Inc, or FVC, and its wholly owned subsidiary, CUseeMe Networks,
Inc. on an "as is" basis. The transaction closed on March 15, 2005. The
transaction, provided for a cash purchase price of $7,150,000. Due to certain
cash adjustments the actual purchase price was less then $7,000,000. We have
hired approximately thirty-one former employees of FVC that were based in
Nashua, New Hampshire and hired the former Chief Executive Officer of FVC on a
consulting basis. The newly hired employees will be involved in marketing,
selling and supporting the acquired FVC products. We acquired leading software
products that enable interactive voice, video and data collaboration over
IP-based networks. The products provide cost-effective, integrated end-to-end
solutions for large-scale deployments from the desktop to the conference room
and also enable best-of-breed collaborative conferencing solutions to be
extended to ISDN and ATM networks. FVC's Click to Meet(TM) product provides
integrated and scalable desktop conferencing solutions. Click to Meet products
are fully integrated with a single software architecture consisting of the
Conference Server, the Conference Client and the Middleware to tie them
together. Click to Meet products are widely deployed worldwide and offer a
robust set of functionalities.

Our Strategy

Our goal is to be the leading provider of solutions that enable real-time
multimedia (voice, video and data) collaboration and communication over packet
networks. We provide solutions at every level - protocol developer toolkits,
professional services, network infrastructure, as well as integrated solutions
that compliment the communication solutions of other vendors such as those from
Cisco, Sony, Microsoft and Alcatel. We believe that the combination of offering
IP-centric networking products, along with software toolkits, positions us as a
key enabling vendor in the evolution of IP communications. Both of our product
lines are essential for building IP networks

                                       15




that support real time voice and video communication with full interoperability
with legacy ISDN/PSTN networks and technologies.

Three  Months  Ended March 31, 2005  Compared  with Three Months Ended March 31,
2004

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 the Far East.

Our revenues increased from $14.3 million for the three months ended March 31,
2004 to $16.3 million for the three months ended March 31, 2005. This increase
was due to a $500,000 increase in sales of our networking products, and a $1.5
million increase in sales of our technology products. The results reflect better
than expected sales with increased sales in North America, Europe, the Middle
East and Asia Pacific.

Revenues from networking products increased from $10.2 million for the three
months ended March 31, 2004 to $10.7 million for the three months ended March
31, 2005, an increase of $500,000 or 5.5%.

Revenues from technology products increased from $4.1 million for the three
months ended March 31, 2004 to $5.6 million for the three months ended March 31,
2005. Revenues from

                                       16




licenses increased from $1.7 million in the three months ended March 31, 2004 to
$2.5 million in the three months ended March 31, 2005. Revenues from royalties
increased from $900,000 in the three months ended March 31, 2004 to $940,000 in
the three months ended March 31, 2005. Maintenance revenues increased from $1.0
million in the three months ended March 31, 2004 period to $1.5 million in the
three months ended March 31, 2005. Revenues from professional services with
respect to research and development increased from $400,000 in the three months
ended March 31, 2004 to $535,000 in the three months ended March 31, 2005.

Revenues from sales to customers in the United States increased from $8.0
million, or 56.0% of revenues, for the three months ended March 31, 2004 to $8.5
million, or 52.1% of revenues for the three months ended March 31, 2005, an
increase of $500,000, or 6.1%. This increase in sales to customers in the United
States was primarily attributable to increased sales to non-Cisco channels and
due to initial revenues from Click to Meet.

Revenues from sales to customers in Europe and the Middle East increased from
$4.0 million for the three month period ended March 31, 2004, or 27.7% of
revenues, to $4.7 million, or 28.6% of revenues, for the three months ended
March 31, 2005.

Revenues from sales to customers in the Asia Pacific region increased from $2.3
million, or 16.2% of revenues, for the three months ended March 31, 2004 to $3.1
million, or 19.3% of revenues, for the three months ended March 31, 2005, an
increase of $800,000 or 35.9% due to strong growth and increased market demand
for our NBU products, particularly in China.

Cost of Revenues. Cost of revenues decreased from $3.1 million for the three
month period ended March 31, 2004 to $2.8 million for the three months ended
March 31, 2005, a decrease of $300,000, or 10.4%. Gross profit as a percentage
of revenues increased from 78.3% for the three months ended March 31, 2004 to
82.9% for the three months ended March 31, 2005, due to the increased proportion
of TBU product sales that have higher profit margins and due to a different mix
of NBU product sales.

Research and Development. Research and development expenses increased from $3.8
million for the three months ended March 31, 2004 to $4.7 million for the three
months ended March 31, 2005, an increase of $900,000 or 23.1%. This increase was
primarily attributable to an increase in the number of research and development
personnel.

Marketing and Selling. Marketing and selling expenses remain constant at
approximately $5.8 million for the three months ended March 31, 2004 and 2005.
Marketing and selling expenses as a percentage of revenues decreased from 40.9%
for the three months ended March 31, 2004 to 35.4% for the three months ended
March 31, 2005. In addition to the temporary savings related to a freeze on new
recruitment, we decreased our marketing and selling expenses in the Asia Pacific
region, where we streamlined operations, reduced the number of distributors and
initiated direct sales to some accounts, thereby reducing commission expenses.

General and Administrative. General and administrative expenses remain constant
at approximately $1.2 million for the three months ended March 31, 2004 and
2005. General and administrative expenses as a percentage of revenues were 8.7%
for the three months ended March 31, 2004 and 7.1% for the three months ended
March 31, 2005.

                                       17




Operating Income. We recorded operating income of $307,000 for the three months
ended March 31, 2004 as compared to operating income of $1.9 million for the
three months ended March 31, 2005.

Financial Income. We recorded financial income of $412,000 for the three months
ended March 31, 2004 compared to $561,000 for the three months ended March 31,
2005. This income was principally derived from the investment of the proceeds of
our March 2000 initial public offering and private placement. Our financial
income increased principally as a result of higher prevailing interest rates.

Liquidity and Capital Resources

We generated $1.7 million from operating activities for the three months ended
March 31, 2005 compared to $2.4 million in the same period in 2004. This amount
was primarily attributable to net income of $2.5 million, a $700,000 decrease in
other receivables and prepaid expenses, and depreciation and amortization
expenses of $450,000. These increases in cash generated by our operating
activities were offset in part by a $1.3 million decrease in other payables,
deferred revenues and accrued expenses and $300,000 increase in trade
receivables.

Net cash used in investing activities was approximately $12.5 million for the
three months ended March 31, 2005. Of the cash used in investing activities
during the three months ended March 31, 2005, $7.0 million was used to acquire
substantially all of the assets of FVC and its wholly owned subsidiary, CUseeMe
Networks, Inc. on March 15, 2005, and $600,000 was used for purchases of
property and equipment.

Our financing activities generated $2.8 million for the three months ended March
31, 2005 compared to $1.3 million in the same period in 2004. This amount is
attributable to proceeds from the exercise of employee stock options.

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. We plan to
pursue strategic initiatives and make operating investments in 2005 as we
position our company to realize on what we perceive to be increasing market
opportunities in the coming years. We anticipate that our cash resources will be
used primarily to fund our operating activities, as well as for capital
expenditures. We may establish additional operations as we expand globally.

On February 28, 2001, we announced that our board of directors had authorized
the repurchase of up to 10% of our outstanding shares in open market
transactions from time to time at prevailing market prices. We completed the
share repurchase program in the first fiscal quarter of 2002, having purchased
1,866,115 ordinary shares at a total cost of $11.8 million, or an average price
of $6.30 per share. At the beginning of 2003, we began to reissue the
repurchased shares upon exercise of employee stock options.

On August 28, 2002, we announced that our board of directors had 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

                                       18




ordinary shares at a total cost of $78,000, or an average price of $5.55 per 
share.  We did not repurchase any shares in 2004.

As of December 31, 2004 we reissued all of the ordinary shares purchased under
our repurchase programs.

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.

Second Quarter 2005 Guidance

o    Second quarter net sales are expected to be approximately $18.0 million, an
     increase of approximately $2.3 million, or 14.6%,  compared with the second
     quarter of 2004.

o    Net income is expected to increase to  approximately  $2.7 million or $0.12
     per share, a 140% increase compared with the second quarter of 2004.

These projections are subject to substantial uncertainty that could cause our
future results to differ materially from the guidance we have provided.



3.   Quantitative And Qualitative Disclosure About Market Risks
     ----------------------------------------------------------

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

Interest Rate Risk

As of March 31, 2005, we had cash and cash equivalents and short-term
investments of $75.3 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 AA. 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.

                                       19






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 2005, the NIS has appreciated approximately 1.2% against
the dollar. The appreciation has resulted in a deflation rate in Israel, which
was approximately 0.6% in the first three month of 2005 compared to an annual
inflation rate of 1.2% in 2004 and to an annual deflation rate of 1.9% in 2003.

Since most of our sales are quoted in dollars, 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.
