                           I. APPOINTMENT OF AUDITORS
                           (Item 1 on the Proxy Card)

     Our company's Audit  Committee and Board of Directors have  recommended the
appointment  of Kost Forer Gabbay & Kasierer,  a member of Ernst & Young Global,
registered independent public accountants,  as our independent auditors for year
2005.

     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 recommended by our company's Audit Committee and the Board
     of Directors of the company, as the independent  auditors of our company to
     conduct the annual audit of our  financial  statements  for the year ending
     December  31,  2005,  and to  authorize  the Audit  Committee  to fix their
     remuneration."

     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  auditors,  or if the Audit  Committee  removes  Kost Forer Gabbay &
Kasierer as our independent auditors, the Audit Committee will recommend another
independent  public accounting firm. The engagement of a new independent  public
accounting firm for year 2005 will be subject to approval by our shareholders at
the 2006 Annual Meeting of the Shareholders.

     The  affirmative  vote of the holders of a majority of the ordinary  shares
represented at the Meeting in person or by proxy and entitled to vote and voting
thereon  will  be  necessary  for   shareholders'   approval  of  the  foregoing
resolution.

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


                     II. ELECTION OF TWO CLASS "A" DIRECTORS
                           (Item 2 on the Proxy Card)

     At our 2004  annual  general  meeting  of  shareholders,  our  shareholders
approved  an  amendment  to  our   Articles  of   Association   to  provide  for
classification of the non-external  members of our Board of Directors into three
classes.  Gadi Tamari,  our Chief  Executive  Officer,  was elected as a Class A
director to serve for a one year term until our 2005 annual  general  meeting of
shareholders.  Andreas  Mattes was  elected as a Class B director to serve for a
term ending as of our 2006 annual general meeting of shareholders. Zohar Zisapel
and Efraim  Wachtel were elected as Class C directors to serve for a term ending
as of our 2007 annual general meeting of  shareholders.  Liora  Katzenstein will
serve as an outside director pursuant to the provisions of the Israeli Companies
Law, for her second  three-year  term,  until our 2006 annual general meeting of
shareholders,  following  which the  service  of Ms.  Katzenstein  as an outside
director may not be extended.  Joseph Atsmon will serve for a three-year term as
an outside  director  pursuant to the  provisions  of the Israeli  Companies Law
until our 2006  annual  general  meeting of  shareholders,  following  which his
service as an outside director may be renewed for only one additional three-year
term.

     In accordance with the new NASDAQ Marketplace  Rules,  effective as of July
31,  2005,  all  directors  of the  Company are  nominated  by a majority of our
independent directors. The independent directors of the Company met in executive
sessions  and have  proposed  the  election of Mr.  Tamari and Mr. Dan Barnea to
serve as Class A directors  for a term of three  years until the annual  general
meeting of shareholders to be held in 2008 or until their successors are elected
and  qualified.  Notwithstanding  the  foregoing,  Mr.  Tamari  will  serve as a
director  of the  Company  so long as he is the Chief  Executive  Officer of the
Company.  The  election of Mr.  Barnea as an  independent  director  (within the
meaning of the NASDAQ  Marketplace  Rules) of the Company will allow the Company
to have a Board of Directors consisting of a majority of independent  directors,
as required by the new NASDAQ Marketplace Rules.

     Gadi  Tamari,  age 59, has served as our chief  executive  officer and as a
director since April 2001. From November 1999 to April 2001, Mr. Tamari was vice
president,  international  operations, of the OpenNet Softswitch organization of
Lucent  Technologies.  Prior  thereto  and  since  1996,  Mr.  Tamari  was chief
operating officer of Excel Switching Corporation,  responsible for international
sales,  operations,  marketing and customer support.  Mr. Tamari also served for
many years in senior management positions

                                       2





with a number of telecommunications  companies.  Mr. Tamari holds a B.Sc. degree
in mechanical  engineering and a M.Sc. degree in industrial engineering from the
Technion,  Israel  Institute of Technology,  and attended  Harvard  University's
Advanced Management Program.

     Mr.  Barnea,  age  60,  is  the  senior  vice  president  of  Research  and
Development,  BMC Software, Inc. a leading provider of enterprise management. In
this  position,  Mr.  Barnea is  responsible  for all product and  technological
related  functions  that  align  around BMC  Software's  core  competencies  and
high-potential  businesses.  Mr.  Barnea  joined BMC  Software  in 1999 upon its
acquisition of New Dimension  Software where he held the post of Chief Executive
Officer.  He is credited with the  significant  turnaround  within New Dimension
Software,  a success  that  catapulted  the company  into the  forefront  of the
systems  management  industry.  Mr.  Barnea has held several  senior  management
positions in technology  companies  including,  Chief Executive Officer of Laser
Industries,  general  manager for Indigo,  and vice  president  of research  and
development  for  Elscint.  Mr.  Barnea  holds  a  B.Sc.  degree  in  Electrical
Engineering  and a M.Sc.  degree in  Computer  Science,  both from the  Technion
Israel Institute of Technology.

     The  affirmative  vote of the holders of a majority of the ordinary  shares
represented at the Annual Meeting in person or by proxy and entitled to vote and
voting  thereon will be  necessary  for the  election of each  director.  Should
either of the nominees for director not be available for  election,  the proxies
will be voted for a substitute nominee  designated by the independent  directors
of the Board of  Directors.  It is not expected that either of the nominees will
be unavailable.

     The Board of  Directors  recommends a vote FOR the election of the nominees
for Director.


      III. APPROVAL OF REMUNERATION FOR DAN BARNEA, AN INDEPENDENT DIRECTOR
                           (Item 3 on the Proxy Card)

     As required by the Israel  Companies  Law,  the terms of  remuneration  for
directors of a company requires shareholder approval.  Our independent directors
and Board of  Directors  has  approved  the grant of options to  purchase  up to
50,000 ordinary shares to Mr. Dan Barnea, an independent  director.  This option
grant has the following  terms:  the exercise  price shall be the closing market
price of our  ordinary  shares on the last  trading  date prior to the  Meeting;
quarterly vesting over sixteen (16) calendar  quarters  beginning June 19, 2005;
exercisable until the earlier of Mr. Barnea's  resignation or the termination of
his position as a director of the Company; and expiration of the options, if not
exercised or expired earlier, on June 19, 2015.

     The following resolution will be offered at the Meeting:

          "RESOLVED,  to approve the grant of options to Mr.  Barnea to purchase
     up to 50,000 ordinary shares of our company with the following  terms:  the
     exercise price shall be the closing market price for our company's ordinary
     shares on the last  trading date prior to the  Meeting;  quarterly  vesting
     over sixteen (16) calendar  quarters  beginning June 19, 2005;  exercisable
     until the earlier of Mr.  Barnea's  resignation  or the  termination of his
     position as a director of our company;  and  expiration of the options,  if
     not exercised earlier, on June 19, 2015."

     The  affirmative  vote of the holders of a majority of the ordinary  shares
represented at the Meeting in person or by proxy and entitled to vote and voting
thereon  will  be  necessary  for   shareholders'   approval  of  the  foregoing
resolution.

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


                                IV. OTHER MATTERS


     The Board of  Directors  does not  intend to bring any  matters  before the
Meeting  other  than  those  specifically  set forth in the Notice of the Annual
