RADVISION to Begin Reporting Annual Reports on Form 20-F

Business Wire, March 14, 2005

FAIR LAWN, N.J. -- RADVISION (Nasdaq: RVSN) announced today that it will begin filing its Annual Reports with the U.S. Securities and Exchange Commission on Form 20-F for foreign private issuers, effective with the year ended December 31, 2004. Previously the Company, which is headquartered in Israel, had voluntarily filed its Annual Reports on Form 10-K. Despite this change, the Company intends to continue to report its financial results on a schedule consistent with its current disclosure practices. The Company also plans to timely furnish its quarterly financial statements to the Securities and Exchange Commission under Form 6-K.

RADVISION noted that it is taking this action to avail itself of the extended deadline for compliance with Section 404 of the Sarbanes-Oxley Act granted by the Securities and Exchange Commission to foreign private issuers that file on Form 20-F.

RADVISION further noted that it believes it has appropriate management controls over financial reporting and that it intends to fully meet its new deadline for compliance with Section 404, which will apply to its year ending December 31, 2006.
