Proxy Procedure

         Only holders of record of our ordinary shares, par value of NIS 0.1 per
share, as of the close of business on May 9, 2006, are entitled to notice of,
and to vote in person or by proxy at, the Meeting.

         Shares eligible to be voted and for which a proxy card is properly
signed and returned and actually received by our transfer agent or at our
registered office in Israel at least forty-eight (48) hours prior to the
beginning of the Meeting will be voted as directed. If directions are not given
or directions are not in accordance with the options listed on a signed and
returned proxy card, such shares will be voted FOR the nominees for director and
outside director and each proposition for which the Board of Directors
recommends a vote FOR. Unsigned or unreturned proxies, including those not
returned by banks, brokers or other record holders, will not be counted for
quorum or voting purposes.

         We will bear the cost of soliciting proxies from our shareholders.
Proxies will be solicited by mail and may also be solicited personally or by
telephone by our directors, officers and employees. We will reimburse brokerage
houses and other custodians, nominees and fiduciaries for their expenses in
accordance with the regulations of the U.S. Securities and Exchange Commission
concerning the sending of proxies and proxy material to the beneficial owners of
stock.

         You may vote by submitting your proxy with voting instructions by mail
if you promptly complete, sign, date and return the accompanying proxy card in
the enclosed self-addressed envelope to our transfer






agent or to our registered office in Israel at least forty-eight (48) hours
prior to the appointed time of the Meeting. You may revoke your proxy at any
time prior to the exercise of authority granted in the proxy by giving a written
notice of revocation to our Company Secretary, by submitting a subsequently
dated, validly executed proxy, or by voting in person.

Quorum and Voting

         As of May 9, 2006, the record date for determination of shareholders
entitled to vote at the Meeting, there were outstanding 22,200,364 ordinary
shares. Each ordinary share entitles the holder to one vote.

         The presence of at least two shareholders, holding at least one-third
(1/3) of our issued share capital, represented in person or by proxy at the
Meeting, will constitute a quorum. An affirmative vote of the holders of a
majority of the ordinary shares represented at the Meeting, in person or by
proxy, entitled to vote and voting thereon, is required to approve each of the
proposals, except as otherwise stated in the proposal.

         I. REELECTION OF ANDREAS MATTES AS A CLASS B DIRECTOR TO SERVE
              UNTIL OUR 2009 ANNUAL GENERAL MEETING OF SHAREHOLDERS
                           (Item 1 on the Proxy Card)

         In accordance with our Articles of Association, our Board of Directors
is divided into three classes (other than outside directors), each consisting of
a number of directors equal as nearly as practicable to one-third of the total
number of non-outside directors. Generally, at each annual meeting of
shareholders one class of directors is elected for a term of three-years by a
vote of the holders of a majority of the voting power represented and voting at
such meeting. All the members of our Board of Directors, except the outside
directors (as detailed in Item II below) 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, provided that the total number
of directors will not at any time exceed any maximum number.

         Messrs. Dan Barnea and Gadi Tamari, our former Chief Executive Officer,
were elected to serve as Class A directors until our 2008 annual general meeting
of shareholders. Mr. Tamari resigned from the position of Chief Executive
Officer and director effective as of December 31, 2005. Mr. Andreas Mattes was
elected to serve as a Class B director to serve until our 2006 annual general
meeting of shareholders. Messrs. Zohar Zisapel and Efraim Wachtel were elected
to serve as Class C directors until our 2007 annual general meeting of
shareholders.

         Our directors, other than our outside directors (see Item II below),
are nominated by a majority of our independent directors, as such term is
defined under NASDAQ Marketplace Rules. Our independent directors met in
executive sessions and have proposed the reelection of Mr. Andreas Mattes to
serve as a Class B director for an additional term of three years until the
annual general meeting of shareholders to be held in 2009 or until his successor
is elected and qualified.

         In the event that such named director nominee would be unable to serve,
the proxies will be voted for the election of such other person as shall be
nominated by the independent directors of our company and ratified by our Board
of Directors. We do not have any understanding or agreement with respect to the
future election of the named nominee.

         Set forth below is information about the nominee, including principal
occupation, business history and other directorships held (if any).

         Andreas Mattes has served as a director of our company since February
2000. Since April 1999, Mr. Mattes has served as the president of enterprise
networks of Siemens ICN. From October 1998 until April 1999, Mr. Mattes served
as the president of central sales of Siemens ICN. From June 1997 until October
1998, Mr. Mattes served as the president of international sales of Siemens PN.
From January 1996 until June 1997, Mr. Mattes served as the vice president of
product management of Siemens PN. From October 1985 until January 1996, Mr.
Mattes held various sales, marketing and business administration positions at
Siemens.

                                        2



         The affirmative vote of the holders of a majority of the ordinary
shares represented at the Meeting, in person or by proxy, entitled to vote and
voting thereon, is required to elect the nominee for director.

         The Board of Directors recommends a vote FOR the election of the
nominee for Class B director.

         For the biographies of the directors continuing in office (other than
outside directors, see Item II below), see Item 6.A. "Directors, Senior
Management and Employees -- Directors and Senior Management" of our Annual
Report on Form 20-F for the year ended December 31, 2005 (filed with the U.S.
Securities and Exchange Commission on April 4, 2006), which may be viewed on our
website at www.radvision.com or through the EDGAR website of the Securities and
Exchange Commission at www.sec.gov.

                      II. ELECTION OF TWO OUTSIDE DIRECTORS
                           (Item 2 on the Proxy Card)

         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: an employment relationship; a
business or professional relationship maintained on a regular basis; control;
and service as an officer holder, excluding service as an outside director of a
company that is offering its shares to the public for the first time. In
addition, 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 a company's board of
directors are of the same gender, then at least one outside director must be of
the other gender.

         According to a March 2005 amendment to the Israeli Companies Law,
effective as of January 2006 at least one of the outside directors must be an
accounting and financial expert and all other outside directors must be
professional experts, as such terms are defined by regulations promulgated under
the Israeli Companies Law. This requirement does not apply to outside directors
appointed prior to the March 2005 amendment, however a company can not renew the
appointment of any such outside director for an additional term unless the
outside director is (i) an accounting and financial expert or (ii) a
professional expert and at the time the appointment is to be renewed, an outside
director who is an accounting and financial expert serves on the board of
directors and such other number of directors who are accounting and financial
experts serve on the board of directors as determined by the board of directors
of the company.

         Outside directors are elected by the shareholders. Outside directors
serve for an initial 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 an outside director ceases to meet the statutory qualifications
with respect to his or her appointment or if the outsider director violates his
or her duty of loyalty to the company.

         Any committee of the board of directors that is authorized to exercise
powers vested in the board of directors must include at least one outside
director and the audit committee must include all of the outside directors.

         Prof. Liora Katzenstein was reelected to serve as an outside director
of our company at our 2003 annual general meeting of shareholders for one
additional three-year term until December 2006, following which the service of
Prof. Liora Katzenstein as an outside director may not be extended. Mr. Joseph
Atsmon was elected to serve as an outside director of our company at our 2003
annual general meeting of shareholders for an initial three-year term until
April 2006, following which the service of Mr. Joseph Atsmon as an outside
director may be renewed for only one additional three-year term.

         Accordingly, at the Meeting, shareholders will be asked to reelect Mr.
Joseph Atsmon as an outside director of our company for one additional
three-year term until our 2009 annual general meeting of

                                       3



shareholders or until his successor is elected and qualified. At the Meeting,
shareholders will also be asked to elect Ms. Liora Lev as an outside director of
our company for an initial three-year term, effective upon the expiration of the
service of Prof. Liora Katzenstein as an outside director on December 1, 2006
and until our 2009 annual general meeting of shareholders or until her successor
is elected and qualified. Our Board of Directors has determined that Mr. Joseph
Atsmon and Ms. Liora Lev each qualifies as an outside director within the
meaning of the Israeli Companies Law. Our Board of Directors has further
determined that Mr. Joseph Atsmon qualifies as an accounting and financial
expert and that Prof. Liora Katzenstein and Ms. Liora Lev both qualify as
professional experts, as such terms are defined by regulations promulgated under
the Israeli Companies Law.

         Set forth below is information about each of the nominees for outside
director, including principal occupation, business history and other
directorships held (if any).

         Joseph Atsmon has served as an outside director of our company since
June 2003. Since July 2001, Mr. Atsmon has served as a member of the board of
directors and audit committee of Nice Ltd. and Ceragon Networks Ltd. and
currently also serves as a member of the board of directors, audit committee and
compensation committee of VocalTec Communications Ltd. From July 2001 until
November 2002, Mr. Atsmon served as Chairman of Discretix Ltd. From 1995 until
2000, Mr. Atsmon served as chief executive officer of Teledata Communication
Ltd., a public company acquired by ADC Telecommunication Inc. in 1998. From 1986
until 1995, Mr. Atsmon served in various positions at Tadiran Ltd., among them
as division president and corporate vice president for Business Development. Mr.
Atsmon received a B.Sc. in Electrical Engineering, summa cum laude, from the
Technion, Israel Institute of Technology.

         Liora Lev is the founder and has served as general partner of Ascend
Technology Ventures since 1999. Of the portfolio companies of Ascend Technology
Ventures, Ms. Lev currently serves as chairperson of Columbus Application
Provider and as a member of the board of directors of SintecMedia Ltd.,
Intellinx Ltd. and Can-Fite BioPharma Ltd. (publicly traded on the Tel Aviv
Stock Exchange). From 1994 until 2000, Ms. Lev served as Commissioner of the
Israel Securities Authority and as a member of the Israeli Accounting Standards
Board. From 1992 until 1998, Ms. Lev served as chief financial officer and was
in charge of the chief information officer of Ashtrom Group. Ms. Lev is a
certified public accountant in Israel, with over 20 years of experience in
business management, information systems management and finance of public and
private companies. Ms. Lev holds a B.A. in Accounting and Economics and a M.Sc.
in Management Science, specializing in information systems, both from Tel Aviv
University. Ms. Lev is also a graduate of the Advanced Management Program,
Harvard Business School.

         The election of each of the nominees for outside director requires the
affirmative vote of a majority of ordinary shares represented at the Meeting, in
person or by proxy, entitled to vote and voting on the matter, provided that
either (i) the shares voting in favor of such resolution include at least
one-third of the shares of non-controlling shareholders who vote on the matter
(excluding the vote of abstaining shareholders), or (ii) the total shareholdings
of the non-controlling shareholders who vote against such proposal do not
represent more than 1% of the voting rights in our company. As of the date
hereof, we do not have any controlling shareholders within the meaning of the
Israeli Companies Law.

         We are not aware of any reason why either of the nominees, if elected,
would be unable or unwilling to serve as an outside director. In the event that
either of the named nominees for outside director would be unable to serve, the
proxies will be voted for the election of such other person or persons as shall
be nominated by the independent directors of our company and ratified by our
Board of Directors.

         The Board of Directors recommends a vote FOR the election of each of
the nominees for outside director.

Outside Director Continuing in Office Until December 2006

         Prof. Liora Katzenstein was elected in December 2000 to serve as an
outside director of our company for an initial term of three years and was
reelected to serve as an outside director of our company at our 2003 annual
general meeting of shareholders for one additional three-year term until
December 2006. A brief biography of Prof. Liora Katzenstein follows.

         Liora Katzenstein specializes in business administration and
entrepreneurship. In 1996, Prof. Katzenstein founded the Israel School of

       III. APPROVAL OF REMUNERATION OF MS. LIORA LEV, AN OUTSIDE DIRECTOR
                           (Item 3 on the Proxy Card)

         The remuneration of outside directors of an Israeli company is
regulated by the Israeli Companies Law, the Companies Regulations (Rules
Regarding Compensation and Expenses to Outside Directors), 2000, as amended, or
the Regulations, and the Companies Regulations (Alleviation for Public Companies
whose Shares are Traded on a Stock Exchange Outside of Israel), 2000, as
amended. Under the Israeli Companies Law and the Regulations, a company must pay
its outside directors compensation in the form of an annual fee and a per
meeting attendance fee in the manner set forth in the Regulations.
Alternatively, instead of payment of the annual and per meeting attendance fees,
a company may elect to compensate its outside directors in proportion to the
compensation paid to the company's "other directors," within the meaning of the
Regulations, provided that the company has at least two "other directors," such
as our company. The term "other director" generally refers to a director who is
not an outside director, a controlling shareholder, an employee or service
provider of the company, an employee, director or service provider of an entity
that is a controlling shareholder of the company or of an entity controlled by a
controlling shareholder of the company, and a director who is not compensated by
the company (compensation in the form of securities does not constitute
compensation for these purposes). The proportionate compensation paid to the
outside directors may not be less than the compensation paid to any "other
director" nor may it exceed the average compensation paid to all of the "other
directors," and shall be paid at the same time that compensation is paid to the
"other directors." A company may also reimburse an outside director for certain
expenses set forth in the Regulations.

         In addition, a company may pay its outside directors compensation in
the form of shares or rights to purchase shares of the company. Such securities
must be granted within the framework of a benefit plan for all of the company's
officers and directors that are not outside directors, except that directors who
are controlling shareholders may be excluded from the grant of such securities.
The amount of securities granted to outside directors and the conditions of
grant (including, among other things, vesting terms, exercise price and exercise
terms) may not be less than those granted to any "other director" nor may they
exceed the average amount of securities and their conditions granted to all of
the "other directors." For this purpose "other director" means a director that
does not receive any other compensation from the company including in the form
of securities.

         A nominee for outside director must be informed of the compensation to
be paid by the company (and in the case of a grant of securities, also the terms
of grant) prior to the nominee's consent to serve in such capacity, and such
compensation may not be changed during any three-year term of service as an
outside director. Also, the compensation paid to each of a company's outside
directors must be the same, regardless of the form of compensation. However, at
the time a new outside director is appointed, a company may decide that at the
end of the term of a serving outside director, the new outside director will
receive compensation that is less than the serving outside director, provided
that the nominee for outside director will be informed of such new compensation
prior to the nominee's consent to serve in such capacity.

         Subject to the election of Ms. Liora Lev as an outside director for an
initial three-year term (see Item II) and shareholder approval of this Item III,
our independent directors and Board of Directors have

                                       5



elected to pay to her, effective as of her appointment as an outside director
and for the duration of her service in such capacity, compensation in the form
of a proportionate fee and to set the amount of such fee at zero.

         In addition, subject to the election of Ms. Liora Lev as an outside
director for an initial three-year term (see Item II) and shareholder approval
of this Item III, our independent directors and Board of Directors have approved
to pay to her, effective as of her appointment as an outside director and for
the duration of her service in such capacity, compensation in the form of a
grant of options to purchase 30,000 of our ordinary shares. In accordance with
the terms of grant, the options are exercisable at a purchase price equal to the
closing price of our ordinary shares on the NASDAQ National Market on the last
trading date prior to December 1, 2006 (the effective date of Ms. Lev's
appointment as an outside director). The options shall vest on a quarterly basis
over a period of four years, in sixteen equal quarterly increments, commencing
on March 1, 2007 (four months after Ms. Lev's appointment as an outside
director), and are exercisable until Ms. Lev's resignation or the termination of
her position as a director of our company, at which time any options that have
not previously been exercised will expire.

         Accordingly, it is proposed that at the Meeting the following
resolutions be adopted:

         "RESOLVED, subject to and effective as of the appointment of Ms. Liora
         Lev as an outside director and for the duration of her service in such
         capacity, to pay to her compensation in the form of a proportionate fee
         and to set the amount of such fee at zero; and

         FURTHER RESOLVED, subject to and effective as of the appointment of Ms.
         Liora Lev as an outside director and for the duration of her service in
         such capacity, to pay to her compensation in the form of a grant of
         options to purchase 30,000 ordinary shares. The terms of such option
         grant, including the exercise price, shall be as described in the Proxy
         Statement for the 2006 Annual Meeting of Shareholders."

         The affirmative vote of the holders of a majority of the ordinary
shares represented at the Meeting, in person or by proxy, entitled to vote and
voting thereon, is required for the approval of the foregoing resolutions.

         The Board of Directors recommends a vote FOR the foregoing resolutions.

                 IV. RATIFICATION OF APPOINTMENT OF INDEPENDENT
                         REGISTERED PUBLIC ACCOUNTANTS
                           (Item 4 on the Proxy Card)

         Our Board of Directors first appointed Kost Forer Gabbay & Kasierer,
registered independent public accountants, a member of Ernst & Young Global, as
our independent public accountants in July 2002 and has reappointed the firm as
our independent public accountants since such time.

         At the Meeting, shareholders will be asked to approve the reappointment
of Kost Forer Gabbay & Kasierer as our independent registered public accountants
for the fiscal year ending 2006, pursuant to the recommendation of our Audit
Committee and Board of Directors. At the Meeting, the shareholders will also be
asked to authorize our Board of Directors to delegate to our Audit Committee the
authority to fix the compensation of our independent registered public
accountants in accordance with the volume and nature of their services. With
respect to fiscal year 2005, we paid Kost Forer Gabbay & Kasierer approximately
$159,000 for audit services, approximately $34,000 for tax-related services and
approximately $10,500 for other services mainly related to implementation of
incentive laws in Israel.

         The following resolution will be offered by our Board of Directors at
the Meeting:

         "RESOLVED, to appoint Kost Forer Gabbay & Kasierer, a member of Ernst &
         Young Global, as the independent registered public accountants of
         RADVISION Ltd. to conduct the annual audit of its financial statements
         for the year ending December 31, 2006; and further resolved to
         authorize the Board of Directors to delegate to the Audit Committee the
         authority to fix the compensation of such independent registered public
         accountants in accordance with the volume and nature of their
         services."

         If the appointment of Kost Forer Gabbay & Kasierer is not approved by
our shareholders, or if Kost Forer Gabbay & Kasierer ceases to act as our
independent registered public accountants, or if the Audit

                                       6


Committee removes Kost Forer Gabbay & Kasierer as our independent registered
public accountants, the Audit Committee will recommend another independent
registered public accounting firm. The engagement of a new independent
registered public accounting firm for year 2006 will be subject to approval by
our shareholders at our 2007 Annual Meeting of Shareholders.

         The affirmative vote of the holders of a majority of the ordinary
shares represented at the Meeting, in person or by proxy, entitled to vote and
voting thereon, is required to approve the foregoing resolution.

         The Board of Directors recommends a vote FOR the foregoing resolution.

         V. REVIEW AND DISCUSSION OF DIRECTORS' REPORT, AUDITOR'S REPORT
            AND THE CONSOLIDATED FINANCIAL STATEMENTS OF THE COMPANY
                      FOR THE YEAR ENDED DECEMBER 31, 2005

         At the Meeting, our Directors' Annual Report to Shareholders, auditor's
report and the audited Consolidated Financial Statements for the year ended
December 31, 2005 will be presented. We will hold a discussion with respect to
the financial statements at the Meeting. This Item will not involve a vote of
