TEL AVIV, Israel (August 31, 2010) – RADVISION Ltd. (Nasdaq & TASE: RVSN) announced today that at an Extraordinary General Meeting of Shareholders held on Tuesday, August 31, 2010, its shareholders approved a self tender offer to purchase 5.0% of its voting power (currently, 976,906 RADVISION shares) for $7.30 per share, net to the seller in cash, less any required withholding taxes and without interest. In accordance with Israeli law, the offer was approved by a special majority, which required the affirmative vote of the holders of a majority of the RADVISION shares present, in person or by proxy, and voting on the matter, and such majority included at least one-third of the votes of disinterested shareholders voting on the matter (not including abstentions).

As required by Israeli law, if the conditions to the offer have been satisfied (or waived, to the extent permitted by applicable law) as of the completion of the initial offer period, RADVISION will provide an additional period of five calendar days during which shareholders may tender their shares. However, shareholders will have no withdrawal rights during such additional five calendar day period.
