RADVISION Reports Strong First Quarter 2007 Results

Wednesday May 2, 8:00 am ET

Revenues Reach First Quarter Record of $24.3 Million

GAAP Diluted EPS Is $0.15; Non-GAAP Diluted EPS Is $0.21 before FAS123R Effect

TEL AVIV, Israel--(BUSINESS WIRE)--RADVISION(R) (Nasdaq: RVSN - News) today
announced that revenues for the first quarter of 2007 reached a record for the
quarter of $24.3 million, a 21% increase from $20.1 million reported in the
first quarter of 2006.

Operating income for the first quarter of 2007 was $1.8 million, in line with
the first quarter of 2006. Excluding the effects of stock-based compensation
expense related to the adoption of FAS123R in both periods, the Company achieved
non-GAAP operating income of $3.2 million compared with $2.9 million in the same
period of 2006.

Net income for the first quarter of 2007 was $3.5 million, or $0.15 per diluted
share compared with $2.9 million or $0.13 per diluted share in the 2006 first
quarter. Excluding the effect of stock-based compensation expense which amounted
to $1.3 million or $0.06 per diluted in the 2007 first quarter and $1.0 million
or $0.04 per diluted share in 2006 first quarter, non-GAAP net income for the
first quarter of 2007 was $4.9 million or $0.21 per diluted share compared with
$3.9 million or $0.17 per diluted share reported in the first quarter of 2006.

The Company had forecast that 2007 first quarter revenues would approximate
$23.5 million and that net income would approximate $3.0 million or $0.13 per
diluted share including stock-based compensation expense. Excluding the effect
of stock-based compensation expense, the Company expected first quarter 2007
non-GAAP net income to be $4.4 million or $0.19 per diluted share.

Business unit revenues for the first quarter of 2007 consisted of $18.3 million
in Networking Business Unit (NBU) sales, representing an increase of 30% from
the first quarter of 2006, and $6.0 million in Technology Business Unit (TBU)
sales, which were level with the first quarter of 2006. TBU revenues met the
Company's forecast while NBU revenues exceeded it.

The Company ended the first quarter of 2007 with approximately $155.8 million in
cash and liquid investments, equivalent to $6.98 per basic share, and an
increase of $10.2 million from December 31, 2006. The increase reflects cash
flow from operations of $7.2 million and cash flow from the exercise of options
of $3.8 million offset in part by $800,000 of capital expenditures.

Boaz Raviv, Chief Executive Officer, commented: "Our first quarter growth was
driven by continued strong demand for our SCOPIA(TM) video platform in the room
conferencing market and the success of our channel partner relationships led by
Cisco. In total, our room conferencing revenues were almost double those of the
first quarter last year as were our revenues through Cisco. This was accompanied
by a substantial increase in our room conferencing sales through other channels.
In addition, we recognized $1.3 million in revenues in the first quarter from
the final delivery of products to the DVS II project with Northup Grumman, which
we announced at the end of 2005.

"We have now introduced SCOPIA(TM) Desktop, which we believe represents another
major advance in the Unified Communications market place. SCOPIA Desktop is a
simple solution that extends the reach of traditional room conferencing to
remote users without complex software installations, licensing fees or firewall
transversal problems. It is bundled with our SCOPIA MCU and was developed using
elements from our Click to Meet(R) desktop software. Initial market response has
been very exciting.






"Revenues directly from Click to Meet, which integrates advanced video into a
variety of desktop environments, totaled $1.1 million in the first quarter,
including continued sales to the Federal market. We also completed installation
of Click to Meet for Lotus Sametime at two IBM centers in the first quarter. A
service provider in Europe, which is standardizing on the Microsoft Windows
Communicator and Live Meeting, has initiated a trial using Click to Meet as the
video solution. With the introduction of SCOPIA Desktop, we expect the
distinction between our room conferencing and desktop sales to be increasingly
blurred.

"In the 3G mobile market, we continued to see strong traction for our SCOPIA(TM)
Interactive Video Platform, which enables rapid development and deployment of
video services by mobile operators and application service providers, as well as
additional sales of our SCOPIA(TM) 3G Video Gateway. Total 3G revenues were $1.8
million for the first quarter.

"Our Technology Business Unit achieved on-target revenues in the first quarter.
With the introduction of new tools and testing solutions in accordance with our
roadmap, we continued advancing our technology leadership and penetrating new
market segments."

Mr. Raviv concluded: "The strong first quarter gave us a good start to 2007. We
plan to continue our progress throughout the year."

Guidance

The following statements are forward-looking, and actual results may differ
materially.

The Company expects revenues for the second quarter of 2007 to be approximately
$25.0 million and net income to approximate $3.7 million or $0.16 per diluted
share. This includes stock-based compensation expense related to the adoption of
FAS123R of $1.4 million or $0.06 per diluted share. Excluding this item, second
quarter 2007 non-GAAP net income is expected to be $5.1 million or $0.22 per
diluted share. That compares to second quarter 2006 revenues of $22.0 million
and net income of $3.2 million or $0.14 per diluted share. This includes
stock-based compensation expense related to the adoption of FAS123R of $1.2
million or $0.06 per diluted share. Excluding this item, net income for the
second quarter of 2006 was $4.4 million or $0.19 per diluted share. (Full
details are available on the Company's web site at www.radvision.com.)

GAAP versus NON-GAAP Presentation

To supplement the consolidated financial statements presented in accordance with
generally accepted accounting principles ("GAAP"), the Company uses non-GAAP
measures of operating results, net income and earnings per share, which are
adjusted from results based on GAAP to exclude the expenses recorded for stock
compensation in accordance with SFAS 123(R). These non-GAAP financial measures
are provided to enhance overall understanding of the current financial
performance and prospects for the future. Specifically, the Company believes the
non-GAAP results provide useful information to both management, and investors as
these non-GAAP results exclude the expenses recorded for stock compensation in
accordance with SFAS 123(R) that the Company believes are not indicative of the
core operating results. Further, these non-GAAP results are one of the primary
indicators management uses for assessing the Company's performance, allocating
resources and planning and forecasting future periods. These measures should be
considered in addition to results prepared in accordance with GAAP, but should
not be considered a substitute for or superior to GAAP results. These non-GAAP
measures may be different than the non-GAAP measures used by other companies.
