                                       25

NOTE 1:  SIGNIFICANT ACCOUNTING POLICIES

     a.   The significant  accounting  policies  applied in the annual financial
          statements  of  the  Company  as of  December  31,  2001  are  applied
          consistently  in  these  financial  statements.

     b.   Recently issued  accounting  standards:  In August 2001, the Financial
          Accounting  Standards Board issued  Statement of Financial  Accounting
          Standards  No.  144,  "Accounting  for the  Impairment  or Disposal of
          Long-Lived Assets" ("FAS 144"), which addresses  financial  accounting
          and reporting for the impairment or disposal of long-lived  assets and
          superseded SFAS No. 121,  "Accounting for the Impairment of Long-Lived
          Assets  and  for  Long-Lived  Assets  to  be  Disposed  Of",  and  the
          accounting and reporting  provisions of APB Opinion No. 30, "Reporting
          the Results of Operations  for a Disposal of a Segment of a Business".
          FAS 144 is effective  for fiscal years  beginning  after  December 15,
          2001, with earlier application encouraged. The Company adopted FAS 144
          as of January 1, 2002 and it does not expect that the  adoption of the
          Statement  will have a  significant  impact if any,  on the  Company's
          financial position and results of operations.

          FASB  recently  also  issued  SFAS  No.  146   "Accounting  for  Costs
          Associated  with Exit or Disposal  Activities"  (SFAS 146").  SFAS 146
          addresses financial accounting and reporting for costs associated with
          exit or disposal  activities and nullifies  Emerging Issues Task Force
          (EITF) Issue No. 94-3,  "Liability  Recognition  for Certain  Employee
          Termination  Benefits  and Other Costs to Exit an Activity  (including
          Certain  Costs  Incurred  in  a  Restructuring)".  SFAS  146  improves
          financial   reporting  by  requiring  that  a  liability  for  a  cost
          associated  with  an exit  or  disposal  activity  be  recognized  and
          measured  initially at fair value only when the liability is incurred.
          The  provisions  of  SFAS  146 are  effective  for  exit  or  disposal
          activities  that are initiated  after  December 31, 2002.  Adoption of
          SFAS 146 is not  expected to have a material  effect on the  Company's
          financial position or operating results.

NOTE 2: UNAUDITED INTERIM FINANCIAL STATEMENTS

          The accompanying  unaudited interim consolidated  financial statements
          have been prepared in accordance  with generally  accepted  accounting
          principles for interim financial information. Accordingly, they do not
          include  all the  information  and  footnotes  required  by  generally
          accepted accounting principles for complete financial  statements.  In
          the  opinion of  management,  all  adjustments  (consisting  of normal
          recurring accruals)  considered necessary for a fair presentation have
          been included.

Item 2. Management's  Discussion and Analysis of Financial Condition and Results
        of Operations

The following is management's discussion and analysis of certain significant
factors which have affected our financial position and operating results during
the periods included in the accompanying condensed consolidated financial
statements.

The discussion and analysis which follows in this quarterly report may contain
trend analysis and other forward-looking statements within the meaning of
Section 21E of the Securities Exchange Act of 1934 which reflect our current
views with respect to future events and financial results. These include
statements regarding our earnings, projected growth and forecasts, and similar
matters that are not historical facts. We remind shareholders that
forward-looking statements are merely predictions and therefore are inherently
subject to uncertainties and other factors that could cause the future results
to differ materially from those described in the forward-looking statements.
These uncertainties and other factors include, but are not limited to, the
uncertainties and factors included in the "Risk Factors" contained in our Annual
Report on Form 10-K for the fiscal year ended December 31, 2001.

Overview

We are a leading designer, developer and supplier of products and technology
that enable real-time voice, video and data communications over packet networks,
including the Internet and other IP networks.

We were incorporated in January 1992, commenced operations in October 1992 and
commenced sales of our products in the fourth quarter of 1994. Before that time,
our operations consisted primarily of research and development and recruiting
personnel. In 1995, we established a wholly owned subsidiary in the United
States, RADVision Inc., which conducts our sales and marketing activities in
North America. In 2000, we established a wholly owned subsidiary in Hong Kong,
RADVision HK Ltd, which conducts our marketing activities in Asia Pacific. In
2001, we established a wholly owned subsidiary in the United Kingdom, RADVision
(UK) Ltd, which conducts our marketing activities in England.

Critical Accounting Policies

The following discussion and analysis of our financial condition and results of
operations are based upon our condensed consolidated financial statements, which
have been prepared in accordance with accounting principles generally accepted
in the United States of America. The preparation of these financial statements
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amounts of
sales and expenses during the reporting periods. Areas where significant
judgments are made include, but are not limited to: inventory valuation and
revenue recognition. Actual results could differ materially from these
estimates.

Inventories. Inventories are stated at the lower of cost or market. Cost is
determined by the moving average method, inventories write-offs and write-down
provisions are provided to cover risks arising from slow-moving items or
technological obsolescence.

Revenue Recognition. Revenues from sales of products and technology are
recognized in accordance with Statement of Position (SOP) 97-2, as amended by
SOP 98-9, upon delivery, when collection is probable, the vendor's fee is fixed
or determinable and persuasive evidence of an arrangement exists. Provided that
all other elements of SOP 97-2 are met, revenues are recognized upon delivery,
whether the customer is a distributor or the final end user. Revenues for
maintenance and support services are deferred and recognized ratably over the
service period.

In accordance with SOP 97-2, revenues for multi-element arrangements, that is,
sales of products or technology in conjunction with post-contract customer
support services, are segregated. Revenues allocated to the delivered elements
are recognized upon delivery, provided that the other elements of SOP 97-2 are
satisfied. Revenues allocated to the undelivered elements (post-contract
customer support services) are deferred and recognized ratably over the service
period. The portion of the fee for multi-element arrangements allocated to the
undelivered elements (post-contract customer support services) is based on
vendor-specific objective evidence determined, in the case of post-contract
customer support services, based on the annual renewal rate for such services
actually charged to customers for years subsequent to the first year following
sale. The remaining portion of the fee is allocated to the delivered elements
based on the residual value method.

Revenues from products sales are recognized in accordance with Staff Accounting
Bulletin No. 101 "Revenue Recognition in Financial Statements" ("SAB No. 101")
when the following criteria are met: persuasive evidence of an arrangement
exists, delivery of the product has occurred, the fee is fixed or determinable
and collectibility is probable. The Company has no obligation to customers after
the date on which products are delivered. Revenues from maintenance and updates
are recognized over the term of agreement.

Deferred revenues include unearned amounts received under maintenance contracts,
and amounts billed to customers but not yet recognized as revenues.


Revenues

We generate revenues from sales of our networking products that are primarily
sold in the form of stand-alone products, and our technology products that are
primarily sold in the form of software development kits, as well as related
maintenance and support services. We generally recognize revenues from the sale
of our products upon shipment and when collection is probable. Revenues
generated from maintenance and support services are deferred and recognized
ratably over the period of the term of service. We price our networking products
on a per unit basis, and grant discounts based upon unit volumes. We price our
software development kits on the basis of a fixed-fee plus royalties from
products developed using the software development kits. We sell our products and
technology through direct sales and various indirect distribution channels in
North America, Europe, the Far East and Israel.

Three Months  Ended September 30, 2001 Compared with Three Months Ended
September 30, 2002

Revenues. Revenues increased from $10.2 million for the three months ended
September 30, 2001 to $12.2 million for the three months ended September 30,
2002, an increase of $2.0 million, or 19.6%. This increase was due to a $2.9
million, or 46.8%, increase in sales of our networking products, and a decrease
of $900,000, or 22.5%, in sales of technology products.

Revenues from networking products increased from $6.2 million for the three
months ended September 30, 2001 to $9.1 million for the three months ended
September 30, 2002. The increase in revenues from networking products is
attributable to an increase in demand for these units as customers moved from
integrated services digital networks, or ISDN, to IP-based networks.

Revenues from technology products decreased from $4.0 million for the three
months ended September 30, 2001 to $3.1 million for the three months ended
September 30, 2002. This decrease in revenues was primarily attributable to
decreased market demand as budgets for these products declined due to the
worldwide economic downturn.

Revenues from sales to customers in the United States decreased from $5.8
million, or 56% of revenues, for the three months ended September 30, 2001, to
$5.4 million, or 44.3% of revenues, for the three months ended September 30,
2002, a decrease of $400,000, or 6.9%. This decrease in sales was primarily as a
result of the ongoing softness in enterprise spending in the United States.

Revenues from sales to customers in Europe increased from $2.5 million, or 24.5%
of revenues, for the three months ended September 30, 2001, to $3.0 million, or
24.5% of revenues, for the three months ended September 30, 2002, an increase of
$500,000, or 20.0%. This increase in sales was primarily attributable to
increased sales efforts in this region.

Revenues from sales to customers in the Far East increased from $1.6 million, or
15.7% of revenues, for the three months ended September 30, 2001, to $3.3
million, or 27.0% of revenues, for the three months ended September 30, 2002, an
increase of $1.7 million, or 106.2%. This increase in sales was primarily
attributable to increased sales efforts in this region.

Revenues from sales to customers in Israel increased from $0.3 million, or 2.9%
of revenues, for the three months ended September 30, 2001, to $0.5 million, or
4.1% of revenues, for the three months ended September 30, 2002, an increase of
$200,000, or 66.7%.

Cost of Revenues. Cost of revenues increased from $2.1 million for the three
month period ended September 30, 2001 to $2.6 million for the three months ended
September 30, 2002, an increase of $500,000, or 23.8%. Gross profit as a
percentage of revenues decreased slightly from 79.4% for the three months ended
September 30, 2001 to 78.5% for the three months ended September 30, 2002.

Research and Development. Research and development expenses, decreased from $4.3
million for the three months ended September 30, 2001 to $3.8 million for the
three months ended September 30, 2002, a decrease of $500,000, or 11.6%. This
decrease was primarily attributable to a decrease in the number of research and
development personnel whom we employed. We have decreased our research and
development personnel consistent with the scope of our research and development
programs. Research and development expenses as a percentage of revenues
decreased from 42.3% for the three months ended September 30, 2001 to 31.4% for
the three months ended September 30, 2002.

Marketing and Selling. Marketing and selling expenses increased from $3.7
million for the three months ended September 30, 2001 to $4.6 million for the
three months ended September 30, 2002, an increase of $900,000, or 24.3%. We
increased our sales and marketing expenses in response to current and expected
continued improvement in the market for our products. Marketing and selling
expenses as a percentage of revenues increased from 36.2% for the three months
ended September 30, 2001 to 38.2% for the three months ended September 30, 2002.

General and Administrative. General and administrative expenses remained
constant at a slightly less than $1.1 million for both periods. General and
administrative expenses as a percentage of revenues were 10.3% for the three
months ended September 30, 2001 and 8.8% for the three months ended September
30, 2002.

Operating Income (Loss). We had an operating loss of $1.0 million for the three
months ended September 30, 2001 compared to operating income of $15,000 for the
three months ended September 30, 2002 principally as a result of our increased
revenues.

Financial Income. We had financial income of $1.1 million for the three months
ended September 30, 2001 compared to $635,000 for the three months ended
September 30, 2002. This income was principally derived from the investment of
the proceeds of our March 2001 initial public offering and private placement.
Our financial income declined principally as a result of lower interest rates
and the use of a portion of our invested funds in connection with our 2001 stock
repurchase program.

Net Income(Loss). Net income for the quarter was $650,000 compared with net
income of $160,000 for the third quarter of 2001.

Nine months Ended  September 30, 2001 Compared with Nine months Ended  September
30, 2002

Revenues. Revenues decreased slightly from $35.5 million for the nine months
ended September 30, 2001 to $35.4 million for the nine months ended September
30, 2002, a decrease of $110,000.

Revenues from networking products increased from $22.1 million for the nine
months ended September 30, 2001 to $25.9 million for the nine months ended
September 30, 2002. The increase in revenues from networking products is
attributable to a global increase in demand for these units as customers moved
from integrated services digital networks, or ISDN, to IP-based networks, as
well as from new OEM agreements that generated additional product sales.

Revenues from technology products decreased from $13.4 million for the nine
months ended September 30, 2001 to $9.5 million for the nine months ended
September 30, 2002. This decrease in revenues was primarily attributable to
decreased market demand.

Revenues from sales to customers in the United States decreased from $22.9
million, or 64.5% of revenues, for the nine months ended September 30, 2001, to
$19.8 million, or 55.9% of revenues, for the nine months ended September 30,
2002, a decrease of $3.1 million, or 13.5%. This decrease in sales to customers
in the United States was primarily attributable to the ongoing softness in
enterprise spending in the United States.

Revenues from sales to customers in Europe increased from $6.4 million, or 18%
of revenues, for the nine months ended September 30, 2001, to $6.6 million, or
18.6% of revenues, for the nine months ended September 30, 2002, an increase of
$200,000, or 3.1%.

Revenues from sales to customers in the Far East increased from $4.8 million, or
13.5% of revenues, for the nine months ended September 30, 2001, to $7.4
million, or 20.9% of revenues, for the nine months ended September 30, 2002, an
increase of $2.6 million, or 54.2%. This increase in sales was primarily
attributable to increased sales efforts in this region.

Revenues from sales to customers in Israel increased from $1.4 million, or 3.9%
of revenues, for the nine months ended September 30, 2001, to $1.6 million, or
4.5% of revenues, for the nine months ended September 30, 2002, a increase of
$200,000, or 14.3%.

Cost of Revenues. Cost of revenues decreased from $8.1 million for the nine
months ended September 30, 2001 to $7.7 million for the nine months ended
September 30, 2002, a decrease of $400,000, or 4.9%. Gross profit as a
percentage of revenues increased from 77.3% for the nine months ended September
30, 2001 to 78.1% for the nine months ended September 30, 2002, due to the
increased level of networking products sales that generate a higher level of
profitability.

Research and Development. Research and development expenses decreased from $13.6
million for the nine months ended September 30, 2001 to $11.7 million for the
nine months ended September 30, 2002, a decrease of $1.9 million, or 13.9%. This
decrease was primarily attributable to a decrease in the number of research and
development personnel whom we employed. Research and development expenses as a
percentage of revenues decreased from 38.4% for the nine months ended September
30, 2001 to 33.1% for the nine months ended September 30, 2002.

Marketing and Selling. Marketing and selling expenses increased from $12.9
million for the nine months ended September 30, 2001 to $13.7 million for the
nine months ended September 30, 2002, an increase of $800,000, or 6.2%. We
increased our sales and marketing expenses in response to current and expected
continued improvement in the market for our products. Marketing and selling
expenses as a percentage of revenues increased from 36.3% for the nine months
ended September 30, 2001 to 38.7% for the nine months ended September 30, 2002.

General and Administrative. General and administrative expenses decreased from
$3.5 million for the nine months ended September 30, 2001 to $3.1 million for
the nine months ended September 30, 2002, a decrease of $0.4 million or 11.4%.
This decrease was primarily attributable to a decrease in personnel expenses.
General and administrative expenses as a percentage of revenues was 9.9% for the
nine months ended September 30, 2001 and 8.8% for the nine months ended
September 30, 2002.

One Time Charge. We recorded a one time charge of $3.0 million in the first nine
months of 2001 for severance costs associated with a 13% workforce reduction as
part of our plan to reduce operating expenses.

Operating Loss. Our operating loss decreased from $5.6 million for the nine
months ended September 30, 2001 to $900,000 for the nine months ended September
30, 2002.

Financial Income. Financial income decreased from $3.9 million for the nine
months ended September 30, 2001 to $2.1 million for the nine months ended
September 30, 2002, principally as a result of lower interest rates we derived
from the investment of the proceeds of our March 2001 initial public offering
and private placement and the use of a portion of our invested funds in
connection with our 2001 stock repurchase plan.

Net Income(Loss). Net income for the first nine months of 2002 was $1.2 million
compared with a net loss of $1.8 for the first nine months of 2001.

Liquidity and Capital Resources

From our inception until our initial public offering in March 2001, we financed
our operations through cash generated by operations and a combination of private
placements of our share capital and borrowings under lines of credit. Through
December 31, 1999, we raised a total of approximately $12.2 million in aggregate
net proceeds in four private placements. In March 2000, we sold 4,370,000 of our
ordinary shares in an initial public offering and 590,822 ordinary shares in a
private placement. We received net proceeds of $89.2 million from the public
offering and private placement. As of September 30, 2002, we had approximately
$14.6 million in cash and cash equivalents and our working capital was
approximately $36.2 million.

Net cash provided by operating activities was approximately $3.8 million for the
nine months ended September 30, 2002. This amount was primarily attributable to
an increase of $2.8 million in other payables and accrued expenses, depreciation
expenses of $1.8 million and a decrease in inventories of $800,000. These
increases in cash provided by operating activities were offset in part by an
increase in trade receivables of $1.5 million and increase in other accounts
receivables and prepaid expenses of $900,000.

The decrease in inventory at September 30, 2002 was primarily due to our efforts
to manage our inventory to correspond with the expected need of the networking
market. The increase in accounts receivable at September 30, 2002 was primarily
the result of increased sales in the quarter compared to the lower level of
sales during the last months of 2001.

Net cash provided by investing activities was $5.8 million for the nine months
ended September 30, 2002. During the nine months ended September 30, 2002, $1.0
million of cash used in investing activities was for purchases of property and
equipment.

Net cash used in financing activities was $1.7 million for the nine months ended
September 30, 2002, those funds were primarily used for stock repurchases.

As of September 30, 2002, we had an unused $2.5 million line of credit.

Our capital requirements are dependent on many factors, including market
acceptance of our products and the allocation of resources to our research and
development efforts, as well as our marketing and sales activities. We
anticipate that our cash resources will be used primarily to fund our operating
activities, as well as for capital expenditures. We do not believe that our
capital expenditures and lease commitments will increase for the foreseeable
future due to the anticipated slowdown in the growth of our operations,
infrastructure and personnel. Nevertheless, we may establish additional
operations as we expand globally.

On February 28, 2001, we announced that our Board of Directors authorized the
repurchase of up to 10% of our outstanding ordinary shares in the open market
from time to time at prevailing market prices. We completed the share repurchase
program in the first quarter of 2002, having repurchased a total of 1,866,115
ordinary shares at a cost of $11.8 million. We may use the repurchased shares
for issuance upon exercise of employee stock options or other corporate
purposes.

On August 28, 2002, we announced that our Board of Directors authorized the
repurchase of up to $10 million or 2 million of the company's outstanding
ordinary shares in the open market from time to time at prevailing market
prices. We are awaiting court approval in order to initiate the repurchase
program.

Item 3. Quantitative and Qualitative Disclosure About Market Risk

We currently do not invest in, or hold for trading or other purposes, any
financial instruments subject to material market risk. We invest our cash
surplus in time deposits, cash deposits, U.S. federal agency securities and
corporate bonds with an average credit rating of A2. We currently pay interest
on our equipment term loan facility based on the London interbank offered rate.
As a result, changes in the general level of interest rates directly affect the
amount of interest payable by us under this facility. However, because our
outstanding debt under this facility has never exceeded $218,000, we do not
expect our exposure to market risk from changes in interest rates to be
material.

We cannot assure you that we will not be materially and adversely affected in
the future if inflation in Israel exceeds the devaluation of the NIS against the
dollar or if the timing of the devaluation lags behind inflation in Israel.

Item 4.  Controls and Procedures

Within the 90 days prior to the date of the filing of this Form 10-Q, the
company carried out an evaluation, under the supervision and with the
participation of the company's management, including the company's chief
executive officer and its chief financial officer, of the effectiveness of the
design and operation of the company's disclosure controls and procedures
pursuant to Securities Exchange Act of 1934 Rule 13a-14. Based upon that
evaluation, the company's chief executive officer and chief financial officer
concluded that the company's disclosure controls and procedures are effective in
timely alerting them to material information relating to the company required to
be included in the company's periodic SEC filings.

There have been no significant changes in the Company's internal controls or
other factors which could significantly affect internal controls subsequent to
the date the Company carried out its evaluation.
